BACKGROUND
Diabetes mellitus is associated with carbohydrate, lipid and protein metabolism abnormalities. Uncontrolled hyperglycaemia can result in dysfunction of various organs such as eyes, kidneys, nerves, and heart and blood vessels leading to long-term complications like nephropathy, neuropathy, retinopathy, stroke and ischaemia. The main objective of the study was to identify critical factors in Type 2 diabetes mellitus (Type 2 DM) with metabolic syndrome (mets) compared with Type 2 DM without mets and their association in the development of Type 2 DM to Type 2 DM with mets and cardiovascular complications. This can aid in improving the clinical management and the consequences of the disease.
MATERIALS AND METHODS
The present study was conducted in the Department of Biochemistry, a tertiary care centre in Northern India. All patients who were aged between 35 and 65 years of age were enrolled. Enrolled subjects were divided into three groups, Group I: 50 healthy people; Group II: 50 Type 2 DM without mets; and Group III: 50 Type 2 DM with mets. These patients were subjected to Anthropometric and biochemical parameter assessment.
RESULTS
On comparing Group III with control and Group II significant difference was observed in these parameters, that is, elevated TGs ( = 0.001), reduced high-density lipoprotein (HDL) level ( = 0.001), elevated high-sensitivity C-reactive protein (hs-CRP) (0.011), high serum insulin fasting ( = 0.010), weight ( = 0.021), waist circumference ( = 0.001) and BMI ( = 0.001). In the control group, head circumference was significantly lower compared to Group II ( = 0.001) and Group III ( = 0.001).
CONCLUSION
On the basis of observed observation, it has been suggested that low enzymatic activity with poor glycaemic control may further progress Type 2 DM into Type 2 DM with metabolic syndrome and cardiovascular complications. High hs-CRP concentration and high fasting insulin can be independent predictor of cardiovascular complications.

INTRODUCTION AND PURPOSE
Ensuring proper femoral component alignment post-Total Knee Arthroplasty (TKA) is crucial for normal patellofemoral (PF) kinematics. However, the customary 3° external rotation relative to the Posterior Condylar Axis (PC Axis) may not universally apply, and the expected final femoral component rotation remains unclear in functionally aligned knees. This study examines the relation between the Transepicondylar Axis (TEA) and PC axis, known as Posterior Condylar Angle (PCA) in Indian patients along with factors influencing PCA, and the feasibility of reproducing patient-specific PCA using image-guided Cuvis joint robot.
METHODS
Forty patients (52 Knees) with primary osteoarthritis and varus deformity were prospectively evaluated. Native PCA was determined using CT-based J planner. Pre-operative patellar shape, PF tilt, PF shift, final femoral component rotation (representing post-operative PCA), final patellar tracking, and post-operative functional and radiological assessment at 3 months were recorded.
RESULTS
Study participants averaged 64.3 years of age, with a female-to-male ratio of 23 to 17. Varus deformities varied, with IA2 being most prevalent, and sagittal plane deformities included fixed flexion (34.6 %) and hyperextension (44.2 %). The average PCA was 1.9° (range: 0°-7.3°), with most knees (41 out of 52) below 3°. The majority had Wiberg type 1 patellae, with pre-operative patellar tilt averaging 5.63°, reducing post-operatively to 4.43°. Most patients (37 out of 40) achieved excellent Knee Society functional scores at the 3-month mark. Complications included one case of delayed wound healing and one femoral array pin breakage. Notably, our study revealed a significant deviation in PCA from the commonly reported 3° in Western literature, underscoring the need for region-specific considerations in TKA planning.
CONCLUSION
PCA of our population is statistically different from customary 3° followed with jig system. Image guided Robotics helps to identify patients specific PCA and reproducing the same was more commonly possible in patients with reducible Varus deformity.

Contrast-enhanced FLAIR fat-suppressed (CE-FLAIR-FS) imaging can potentially increase the diagnostic accuracy of uveal diseases and ultimately provide better patient management. This study aimed to determine the diagnostic value of CE-FLAIR-FS imaging versus contrast-enhanced T1-weighted imaging (CE-T1WI) in the assessment of pediatric patients with uveitis. Twenty-one children with uveitis who underwent whole brain magnetic resonance imaging (MRI), including CE-FLAIR-FS and CE-T1WI, were retrospectively included in the study. We evaluated the presence of uveal tract contrast enhancement with thickening, vitreous humor signal abnormality, and accompanying brain abnormalities. The uveal enhancement intensity was assessed semiquantitatively as mild, moderate, and marked uveitis compared to CE-T1WI and CE-FLAIR-FS images. Panuveitis (61.9%) was the most frequent anatomic location, and most of them were idiopathic (47.6%). Of the 42 eyes with clinical uveitis, enhancement of the uveal tract was observed on CE-FLAIR-FS images in 21 eyes (50%), while in 5 eyes (11.9%) on CE-T1WI. The sensitivity of CE-FLAIR-FS in panuveitis was detected to be quite high (80.8%). The number of affected eyes and enhancement degree were found to be higher on CE-FLAIR-FS ( < 0.001). In assessing the severity of uveitis, CE-FLAIR-FS grades were significantly higher and more sensitive than CE-T1WI ( < 0.001, : -4.347). Three patients had vitreous abnormal signals on CE-FLAIR-FS images, but none on CE-T1WI. CE-FLAIR-FS plays a significant role in the diagnosis of pediatric uveitis, identifying the involvement and severity of the uveal inflammation and guiding the appropriate management. It would be beneficial to add it as a standard sequence to the routine MRI protocol for uveal pathologies.

Premenstrual dysphoric disorder (PMDD), a severe form of premenstrual syndrome (PMS), is a serious health disorder that affects patient moods. It is caused by cyclic psychological symptoms and its pathogenesis is still unclear. Abnormalities in the basolateral amygdala (BLA) orexin system, which are important causes of the development of depressive mood, have not been reported in PMDD, so exploring its intrinsic mechanisms is meaningful for enriching the pathomechanisms of PMDD. High performance liquid chromatography was used for the determination of the active ingredients of Jingqianshu granules. Developing a rat model of premenstrual depression using the forced swimming test (FST). The experiment consisted of two parts. In Part 1, the rats were divided into the control group, the model group, the model + Jingqianshu group, and the model + fluoxetine group. The FST, open field test, and elevated plus maze test, were used to assess the behavior of the rats as well as to evaluate the effect of drug intervention. Immunofluorescence and RT-qPCR were used to detect the expression of orexin and its receptors OX1R and OX2R genes and proteins. The expression of Toll-like receptor 4, nuclear factor kappa-B, tumor necrosis factor-α, interleukin 6, and interleukin-1β in the BLA brain region was detected by Western-Blot. In part 2, the rats were injected intracerebrally with orexin-A. Observe the behavioral activities of rats in the control group, model group, and model+orexin-A group. Immunofluorescence was used to detect microglia in the BLA area of rats, and the expression levels of the above inflammatory factors were detected by Western-Blot. The five components of Jingqianshu granules are: paeoniflorin, erulic acid, liquiritin, hesperidin, and paeonol. During the estrous cycle, rats exhibited depressive-like behavior during the non-receptive phase of the behavioral test, which disappeared during the receptive phase. Immunofluorescence and RT-qPCR showed reduced gene and protein expression of orexin, OX1R, and OX2R in the BLA region of rats in the model group.WB showed elevated levels of inflammatory factors. All returned to control levels after drug treatment. In part 2, injection of orexin-A into the BLA brain region of model rats resulted in reduced immunoreactivity of microglia and decreased expression levels of inflammatory factors. Jianqianshu granules can achieve the purpose of treating premenstrual depression by regulating orexin-mediated inflammatory factors, which provides a new idea for further research on the pathogenesis of PMDD. However, the current study is still preliminary and the pathogenesis of PMDD is complex. Therefore, more in-depth exploration is needed.

BACKGROUND AND PURPOSE
Two basic methods for genu valgum correction are osteotomy and internal fixation or external fixator assited correction. External fixators have the advantage of stabilizing fragments before osteotomy allowing better control of fragments and preventing secondary displacements. The purpose of this study was to evaluate the efficacy and complications of fixator assisted correction for genu valgum and internal fixation, using the AO distal femur pediatric osteotomy plate.
MATERIALS AND METHODS
Thirty-six limbs in 26 patients (age 10-16 years) underwent osteotomy in the distal femur at CORA. Open lateral wedge osteotomy was done; the desired position obtained was temporarily stabilized by connecting the pins with the AO external fixator and stabilized with 90 degrees AO distal femur pediatric locking plate and gap grafted with hydroxyapatite bone granules.
RESULTS
Translation of distal fragment was required in 17 osteotomies (53.12%). Osteotomies united within 12 weeks; no non-union was observed. The range of motion was full in all patients. The mean tibiofemoral angle was corrected by 12 degrees and the mean mechanical LDFA was corrected to 87 degrees. There was no secondary deformity, either in the rotational or sagittal plane.
CONCLUSION
This method combines the modularity of external fixator and the advantages of internal fixation.

OBJECTIVE
Cantrell syndrome, a rare congenital disorder, is characterized by a unique collection of defects on the midline abdominal wall, the lower sternum, the anterior diaphragm, and the diaphragmatic pericardium in addition to some form of intracardiac defect. So far, most of the reports on fetuses with Cantrell syndrome worldwide are either case reports or literature reviews, and few comprehensive studies on fetuses with Cantrell syndrome have been reported, especially in domestic literature. This study aims to provide a detailed analysis of 15 cases of Cantrell syndrome fetuses, focusing on their prenatal ultrasound manifestations and postnatal examination outcomes.
METHODS
A retrospective analysis was conducted with 15 cases of fetuses diagnosed with Cantrell syndrome via prenatal ultrasound examinations between March 2018 and July 2023. Ultrasound examinations were performed in accordance with the Guidelines for Obstetric Ultrasound in China, including first-trimester fetal ultrasound scan and routine second-trimester fetal ultrasound scan. Gestational age was evaluated and nuchal translucency (NT) was measured during first-trimester fetal ultrasound scan at 11 to 13+6 weeks. The diagnostic criterion for NT thickening was NT≥3.0 mm and the screening of severe fetal structural malformations was performed, including the screening of the head, the neck, the thorax, the abdominal content, the abdominal wall, the limbs and other structures. During routine second-trimester fetal ultrasound scan, the fetal biometry was assessed and an anatomy survey was performed. Post-induction and postnatal outcomes of fetuses diagnosed with Cantrell syndrome by prenatal ultrasound were followed up by postnatal observation, inquiries with the electronic medical record system, or telephone follow-up. The prenatal ultrasound imaging manifestations and features of the fetuses with Cantrell syndrome, as well as their post-induction or postnatal examination results were comprehensively summarized and analyzed.
RESULTS
The study involved pregnant women of the average age of 30.1±3.5 years, with ultrasound diagnoses made between 11 to 26 weeks of gestation (mean: 13.4±4.0 weeks). Among the 15 cases, there were 10 singleton pregnancies and 5 cases of one twin in a pair of twins. These twins comprised 3 monochorionic diamniotic twins and 2 dichorionic diamniotic twins, with Cantrell syndrome present in one of the twins in all 5 cases. Thirteen cases were diagnosed by fetal ultrasound scan conducted in the first trimester, with 10 being singleton pregnancies and 3 being twin pregnancies (1 monochorionic diamniotic twins and 2 dichorionic diamniotic twins). One case was missed in the first-trimester ultrasound scan, resulting in a missed diagnosis rate of 7.1%. Two cases were diagnosed in second-trimester fetal ultrasound scan, both involving monochorionic diamniotic twins. One case was a referral from another hospital at 19 weeks, while the other was initially not diagnosed for Cantrell syndrome and was diagnosed at 26 weeks. Prenatal ultrasound examinations revealed a consistent pattern of abnormalities across all 15 fetuses, including manifestations of ectopic cordis combined with abdominal protrusion mass. Specifically, 4 cases were diagnosed with omphalocele, 4 with gastroschisis, and the remaining 7 had uncertain coverage of the membrane on the surface of the abdominal protrusion mass. Six fetuses had complete ectopic cordis, while nine had partial ectopic cordis. Fetal echocardiography was performed in 5 cases, revealing intracardiac malformations in 4 cases (80%). Notably, 2 cases were diagnosed in the second trimester, including one with right ventricular hypoplasia accompanied by interventricular septal defect and another with double outlet right ventricle accompanied by interventricular septal defect. Additionally, 2 cases were diagnosed in the first trimester, one with single atrium and single ventricle, and the other with complete transposition of the great arteries. Of the 15 cases of fetuses with Cantrell syndrome, 13 (86.7%) exhibited concomitant malformations in other systems. These included 7 cases of spinal malformations, 4 limb abnormalities, 3 umbilical cord abnormalities, 2 central nervous system malformations, 1 facial malformation, and 2 fetal hydrops. Spinal malformations were the most prevalent concomitant malformation, accounting for 46.7% of all cases. Among the 14 fetuses undergoing NT examination, 7 (50%) had increased NT, and 5 of them had cystic hygroma. All 10 singleton pregnancies underwent induced abortion, and the appearance of the induced fetuses was consistent with the prenatal ultrasound manifestations. In the twin pregnancies, 2 cases experienced intrauterine fetal death, while 2 underwent selective reduction. Notably, 3 of these cases exhibited postnatal appearances consistent with prenatal ultrasound manifestation, while 1 case showed an indistinct appearance after selective reduction during delivery. One case was lost to follow-up. Genetic testing was conducted for 4 induced fetuses, none of which yielded any relevant pathogenic or potentially pathogenic variants.
CONCLUSION
In conclusion, Cantrell syndrome manifests prenatally with ectopic cordis combined with abdominal protrusion mass, often accompanied by intracardiac malformations and other concomitant malformations. While most cases can be diagnosed in the first trimester, there remains the possibility of missed diagnoses, which underscores the importance of close follow-up in the second trimester.

OBJECTIVE
To determine the humoral immunity in advanced maternal-age women with recurrent spontaneous abortion (RSA).
METHODS
A retrospective study was performed between January 2022 and October 2023 in the Department of Reproductive Immunity of Shanghai First Maternity and Infant Hospital. Women with RSA were recruited and multiple autoantibodies were tested. Multivariate logistic regression was performed to compare the associations between different age groups (20 to 34 years old in the low maternal-age group and 35 to 45 years in the advanced maternal-age group) and multiple autoantibodies, while controlling for three confounding factors, including body mass index (BMI), previous history of live birth, and the number of spontaneous abortions. Then, we investigated the differences in the humoral immunity of advanced maternal-age RSA women and low maternal-age RSA women.
RESULT
A total of 4009 women with RSA were covered in the study. Among them, 1158 women were in the advanced maternal-age group and 2851 women were in the low maternal-age group. The prevalence of antiphospholipid syndrome, systemic lupus erythematosus, Sjogren's syndrome, rheumatoid arthritis, and undifferentiated connective tissue disease was 15.6% and 14.1%, 0.0% and 0.1%, 0.9% and 0.9%, 0.3% and 0.0%, and 23.7% and 22.6% in the advanced maternal-age group and low maternal-age group, respectively, showing no statistical difference between the two groups. The positive rates of antiphospholipid antibodies (aPLs), antinuclear antibody (ANA), extractable nuclear antigen (ENA) antibody, anti-double stranded DNA (dsDNA) antibody, anti single-stranded DNA (ssDAN) antibody, antibodies against alpha-fodrin (AAA), and thyroid autoimmunity (TAI) were 19.1% and 19.5%, 6.6% and 6.6%, 9.2% and 10.5%, 2.0% and 2.0%, 2.2% and 1.2%, 5.1% and 4.9%, and 17.8% and 16.8%, respectively. No differences were observed between the two groups. 1.6% of the women in the advanced maternal-age group tested positive for lupus anticoagulant (LA), while 2.7% of the women in the low maternal-age group were LA positive, with the differences being statistically significant (odds ratio=0.36, 95% confidence interval: 0.17-0.78). In the 4008 RSA patients, the cumulative cases tested positive for the three antibodies of the aPLs spectrum were 778, of which 520 cases were positive for anti-β2 glycoprotein Ⅰ antibodies (β2GPⅠ Ab)-IgG/IgM, 58 were positive for aCL-IgG/IgM, 73 were positive for LA, 105 were positive for both β2GPⅠ Ab-IgG/IgM and aCL-IgG/IgM, 17 were positive for both β2GPⅠ Ab-IgG/IgM and LA, 2 were positive for both aCL-IgG/IgM and LA, and 3 were positive for all three antibodies.
CONCLUSION
Our study did not find a difference in humoral immunity between RSA women of advanced maternal age and those of low maternal age.

OBJECTIVE
Infertility affects approximately one-sixth of the people of childbearing age worldwide, causing not only economic burdens of treatment for families with fertility problems but also psychological stress for patients and presenting challenges to societal and economic development. Premature ovarian insufficiency (POI) refers to the loss of ovarian function in women before the age of 40 due to the depletion of follicles or decreased quality of remaining follicles, constituting a significant cause of female infertility. In recent years, with the help of the rapid development in genetic sequencing technology, it has been demonstrated that genetic factors play a crucial role in the onset of POI. Among the population suffering from POI, genetic studies have revealed that genes involved in processes such as meiosis, DNA damage repair, and mitosis account for approximately 37.4% of all pathogenic and potentially pathogenic genes identified. FA complementation group M () is a group of genes involved in the damage repair of DNA interstrand crosslinks (ICLs), including -. Abnormalities in the genes are associated with female infertility and gene knockout mice also exhibit phenotypes similar to those of POI. During the genetic screening of POI patients, this study identified a suspicious variant in . This study aims to explore the pathogenic mechanisms of the genes of the FA pathway and their variants in the development of POI. We hope to help shed light on potential diagnostic and therapeutic strategies for the affected individuals.
METHODS
One POI patient was included in the study. The inclusion criteria for POI patients were as follows: women under 40 years old exhibiting two or more instances of basal serum follicle-stimulating hormone levels>25 IU/L (with a minimum interval of 4 weeks inbetween tests), alongside clinical symptoms of menstrual disorders, normal chromosomal karyotype analysis results, and exclusion of other known diseases that can lead to ovarian dysfunction. We conducted whole-exome sequencing for the POI patient and identified pathogenic genes by classifying variants according to the standards and guidelines established by the American College of Medical Genetics and Genomics (ACMG). Subsequently, the identified variants were validated through Sanger sequencing and subjected to bioinformatics analysis. Plasmids containing wild-type and mutant genes were constructed and introduced into 293T cells. The 293T cells transfected with wild-type and mutant human plasmids and pEGFP-C1 empty vector plasmids were designated as the EGFP - group, the EGFP - group, and the EGFP group, respectively. To validate the production of truncated proteins, cell proteins were extracted 48 hours post-transfection from the three groups and confirmed using GFP antibody. In order to investigate the impact on DNA damage repair, immunofluorescence experiments were conducted 48 hours post-transfection in the EGFP WT group and the EGFP -MUT group to examine whether the variant affected FANCM's ability to localize on chromatin. Mitomycin C was used to induce ICLs damage in both the EGFP - group and the EGFP - group, which was followed by verification of its effect on ICLs damage repair using γ-H2AX antibody.
RESULTS
In a POI patient from a consanguineous family, we identified a homozygous variant in the gene, c.1152-1155del:p.Leu386Valfs*10. The patient presented with primary infertility, experiencing irregular menstruation since menarche at the age of 16. Hormonal evaluation revealed an FSH level of 26.79 IU/L and an anti-Müllerian hormone (AMH) level of 0.07 ng/mL. Vaginal ultrasound indicated unsatisfactory visualization of the ovaries on both sides and uterine dysplasia. The patient's parents were a consanguineous couple, with the mother having regular menstrual cycles. The patient had two sisters, one of whom passed away due to osteosarcoma, while the other exhibited irregular menstruation, had been diagnosed with ovarian insufficiency, and remained childless. Bioinformatics analysis revealed a deletion of four nucleotides (c.1152-1155del) in the exon 6 of the patient's gene. This variant resulted in a frameshift at codon 386, introducing a premature stop codon at codon 396, which ultimately led to the production of a truncated protein consisting of 395 amino acids. experiments demonstrated that this variant led to the production of a truncated FANCM protein of approximately 43 kDa and caused a defect in its nuclear localization, with the protein being present only in the cytoplasm. Following treatment with mitomycin C, there was a significant increase in γ-H2AX levels in 293T cells transfected with the mutant plasmid (<0.01), indicating a statistically significant impairment of DNA damage repair capability caused by this variant.
CONCLUSIONS
The homozygous variant in the gene, c.1152-1155del:p.Leu386Valfs*10, results in the production of a truncated FANCM protein. This truncation leads to the loss of its interaction site with the MHF1-MHF2 complex, preventing its entry into the nucleus and the subsequent recognition of DNA damage. Consequently, the localization of the FA core complex on chromatin is disrupted, impeding the normal activation of the FA pathway and reducing the cell's ability to repair damaged ICLs. By disrupting the rapid proliferation and meiotic division processes of primordial germ cells, the reserve of oocytes is depleted, thereby triggering premature ovarian insufficiency in females.

Sleep is an essential behavior that is still poorly understood. Sleep abnormalities accompany a variety of psychiatric and neurological disorders, and sleep can serve as a modifiable behavior in the treatment of these disorders. Zebrafish () has proven to be a powerful model organism to study sleep and the interplay between sleep and these disorders due to the high conservation of the neuro-modulatory mechanisms that control sleep and wake states between zebrafish and humans. The zebrafish is a diurnal vertebrate with a relatively simple nervous system compared to mammalian models, exhibiting conservation of sleep ontogeny across different life stages. Zebrafish larvae are an established high-throughput model to assess sleep phenotypes and the biological underpinnings of sleep disturbances. To date, sleep measurement in juvenile and adult zebrafish has not been performed in a standardized and reproducible manner because of the relatively low-throughput nature in relation to their larval counterparts. This has left a gap in understanding sleep across later stages of life that are relevant to many psychiatric and neurodegenerative disorders. Several research groups have used homemade systems to address this gap. Here, we report employing commercially available equipment to track activity and sleep/wake patterns in juvenile and adult zebrafish. The equipment allows researchers to perform automated behavior assays in an isolated environment with light/dark and temperature control for multiple days. We first explain the experimental procedure to track the sleep and activity of adult zebrafish and then validate the protocol by measuring the effects of melatonin and DMSO administration. Key features • Allows an isolated and controllable environment to carry out activity and sleep assays in juvenile and adult zebrafish. • Measures activity of zebrafish in life stages later than early development, which requires feeding animals during the assay. • Requires use of a commercially available equipment system and six tanks. • The activity of zebrafish can be tracked for five days including an acclimation step.
