Huang Lian Jie Du Tang attenuates paraquat-induced mitophagy in human SH-SY5Y cells: A traditional decoction with a novel therapeutic potential in treating Parkinson's disease.
Huang Lian Jie Du Tang (HLJDT) is a traditional Chinese medical decoction for heat-fire clearing and detoxication. Theoretically, the cause of Parkinson's disease (PD) has been attributed to the dysregulations of internal wind, phlegm, fire, and stasis. Thus, HLJDT has been used to treat PD. However, the molecular mechanism is unknown. Besides, paraquat (PQ) as an herbicide has been known to impair midbrain dopaminergic neurons, resemblance to the pathology of PD. Thus, the molecular mechanism of HLJDT in treating PD and PQ-induced in vitro PD model was investigated in this study. Primarily, the dose-response of PQ (0.1∼1 mM)-induced neurotoxicity for 24 h was performed in the human neuroblastoma SH-SY5Y cells. The LD of PQ is around 0.3 mM and was applied throughout the following experiments. The neutral red assay was used to estimate cell viability. Co-transfection of the mitochondrial marker and proapoptotic factor genes were applied to measure the release of mitochondrial proapoptotic factors during PQ intoxication and HLJDT protection. The fluorescent dyes were used to detect mitochondrial membrane potential and free radical formation. Western blot and dot-blot analysis and immunocytochemistry were used to estimate the level of proteins related to apoptosis and mitophagy. PINK1 gene silencing was used to determine the significance of mitophagy during PQ intoxication. In this study, HLJDT attenuated PQ-induced apoptosis in SH-SY5Y cells. HLJDT reversed PQ-induced decreased mitochondrial membrane potential and suppressed PQ-induced increased cytosolic and mitochondrial free radical formations and mitochondrial proapoptotic factor releases. Furthermore, HLJDT mitigated PQ-induced increases in full-length PINK1, phosphorylations of Parkin and ubiquitin, mitochondrial translocation of phosphorylated Parkin, and mitophagy. PINK1 gene silencing attenuated PQ-induced neurotoxicity. Therefore, HLJDT attenuated PQ-induced cell death by regulating mitophagy.

Fisch. is used in large quantities in traditional Chinese medicine. It contains flavonoids, saponins, and polysaccharides, with flavonoids being the main active ingredients. In this study, flavonoids were isolated from the roots of Fisch. grown in 21 areas in China by water extraction, alcohol precipitation, polyamide resin separation, and other methods. Fingerprints were established by high performance liquid chromatography (HPLC). There were 15 common peaks in the fingerprints by similarity evaluations of the chromatographic fingerprints. The spectrum-effect relationships between the HPLC fingerprints and pharmacological activities of flavonoids in Fisch., including the heat clearing, detoxifying effects, cough relief, and phlegm elimination effects, were assessed by gray relational analysis and partial least squares regression. After HPLC-quadrupole time-of-flight mass spectrometry and standard comparison, these five identified compounds (liquiritin apioside, neoisoliquiritin, licochalcone A, licochalcone B, and licochalcone C) could be used to evaluate licorice quality with regard to its efficacy. This research provides a scientific basis for improving licorice quality and also establishes a model for modernization of traditional Chinese medicines.

Review
OBJECTIVE
To investigate the correlation between traditional Chinese medicine (TCM) body constitution and ischemic stroke (IS).
METHODS
Literature search was conducted in databases including Wanfang database, Chongqing VIP, China National Knowledge Infrastructure, Embase, and PubMed from inception to November 16, 2020. Observational studies evaluating the association between TCM body constitution and IS were included for analysis. The distribution of body constitutional types in IS patients was pooled into meta-analysis. The correlation between constitution and IS was presented by the odds ratio (OR) and 95% CI through the comparison between IS and the general population.
RESULTS
41 studies involving 11,211 participants were included. Among the nine constitution types, qi-deficiency constitution (QDC), phlegm-dampness constitution (PDC), and blood stasis constitution (BSC) are the common types, accounting for 25% [0.22, 0.29], 23% [0.20, 0.29], and 17% [0.13, 0.22], respectively, in IS patients. The proportion of PDC and QDC among IS patients is 2.34 times and 3.47 times higher than that in the general population, respectively (OR and 95% CI: 2.34 [1.39, 3.94], 3.47 [1.61, 7.50], respectively).
CONCLUSION
PDC and QDC are the common constitutions in IS patients and may have a potential correlation with the incidence of IS. Due to the low or moderate quality of included studies, more well-designed prospective studies are warranted to further evaluate the relationship between TCM constitutions and IS.

Review
Baihe Gujin decoction is one of the most commonly used decoction in traditional Chinese medicine for the treatment of lung cancer. It can nourish yin and moisten the lung as well as prevent phlegm from forming and stop coughing. On the one hand, Baihe Gujin decoction is characterized with extensive application, proven efficacy, a long history, and high safety. On the other hand, Baihe Gujin decoction can induce apoptosis of tumor cells, improve immune function and inhibit inflammation. The main anti-tumor components of this include kaempferol, quercetin, isorhamnetin, glycyrrhizin and β-sitosterol. Clinically, Baihe Gujin decoction can improve the adverse reactions caused by radiotherapy, chemotherapy and immunotherapy for lung cancer, enhance the quality of life of patients, and prolong their survival time. At present, there are a large number of clinical and basic researches on the treatment of lung cancer with Baihe Gujin decoction. In this paper, we mainly discussed the treatment of lung cancer with Baihe Gujin decoction through analyzing basic and clinical researches at home and abroad in the past 20 years. Through the discussion, we aimed to probe deeper into Baihe Gujin decoction for the treatment of lung cancer, thereby providing a broader idea for clinical diagnosis and treatment of lung cancer.

BACKGROUND
The Asthma Daytime Symptom Diary (ADSD) and the Asthma Nighttime Symptom Diary (ANSD) were developed to meet the need for standardized patient-reported measures of asthma symptoms to assess treatment trial outcomes in adults and adolescents.
OBJECTIVE
To determine scoring and evaluate the measurement properties of the ADSD/ANSD.
METHODS
Adolescents (12-17 years) and adults (18+ years) with asthma completed draft 8-item electronic versions of the ADSD/ANSD for 10 days alongside the Adult Asthma Symptom Daily Scales (AASDS) and a Patient Global Impression of Severity (PGIS). Using classical and modern psychometric methods, initial analyses evaluated the performance of ADSD/ANSD items to inform scoring. Subsequent analyses evaluated the reliability and validity of ADSD/ANSD scores.
RESULTS
A demographically and clinically diverse sample (n = 130 adolescents; n = 89 adults) was recruited. Item performance was generally strong. However, items assessing chest pressure and mucus/phlegm demonstrated redundancy and poorer performance and were removed. Principal-components analysis, confirmatory factor analysis, and item response theory supported combining items to form 6-item total ADSD/ANSD scores. Internal consistency (α = 0.94-0.95) and test-retest reliability (intraclass correlation coefficient = 0.86-0.95) were strong. Strong correlations (r = 0.72-0.80) were observed between ADSD scores and AASDS items assessing asthma symptom frequency, bother, and impact on activities. Significant differences (P < .001) in mean ADSD/ANSD scores were observed between groups categorized by asthma severity (PGIS), asthma control, inhaler use, nebulizer use, activity limitations, and nighttime awakenings.
CONCLUSIONS
The ADSD/ANSD items and scores demonstrated strong reliability and validity. Implementation of the measures in interventional studies will enable the evaluation of responsiveness and meaningful within-patient change.

BACKGROUND
Recently, two naval pilots in a two-seat trainer jet were forced to eject urgently due to sudden mechanical failure during night-time training. They were both successfully rescued and sent to the hospital for emergency treatment. In this study, we investigate their ejection injuries and recovery process.
CASE SUMMARY
We analyzed the clinical data of the traumatic condition and recovery process from ejection injuries of two pilots who ejected from a failed trainer jet and survived. After being successfully rescued and sent to the hospital, they were diagnosed with multiple ejection injuries, including eye trauma, limb bone and joint injury, rib and spine injury, and so on. Both cases underwent fluid replacement, acid suppression, nutritional support, hemostasis, bone metabolism improvement, phlegm elimination, psychological measurement, blood circulation promotion and detumescence, physical therapy, and external fixation with braces for 1 mo before being discharged from hospital. They then recuperated in a sanatorium for 2 mo, and the related laboratory tests and supplementary examinations show that they recovered from all the above injuries. After successfully passing the psychological test and physical examination, they returned to flight duty 3 mo after ejection.
CONCLUSION
The causes and conditions of ejection injury in the pilots were very complex. Although they finally recovered quickly and were released, it also serves as a reminder that attention should be paid to pilots' ejection and parachute training in order to significantly reduce ejection injury and improve the ejection success rate. In addition, air defense support personnel should strengthen search and rescue and on-site emergency measures, and locate and rescue pilots in distress as early as possible to reduce subsequent injuries.

AIMS
To observe the clinical efficacy of self-made Lifei Dingchuan decoction combined with western medicine in the treatment of cough variant asthma (phlegm-heat accumulation in the lung syndrome).
MATERIALS AND METHODS
The clinical data of 90 patients with cough variant asthma who were hospitalized in the Department of Respiratory Medicine of our hospital from January 2020 to April 2022 were selected as the research objects, and they were equally divided into the observation group and the reference group according to different treatment methods, 45 cases in each group. The group was treated with traditional montelukast sodium chewable tablet and salmeterol fluticasone mixed powder inhalation, and the observation group was treated with self-made Lifei Dingchuan decoction on the basis of the control group, saturation, pH, partial pressure of oxygen in arterial blood, partial pressure of carbon dioxide, length of stay, and hospitalization costs.
RESULTS
After the patients underwent self-made Lifei Dingchuan decoction, there were significant differences between the observation group and the reference group in terms of heart rate, respiratory rate, blood oxygen saturation, pH value, arterial blood oxygen partial pressure, carbon dioxide partial pressure, and within the group. There was a statistical difference ( < 0.05). The adverse reactions in patients with cough variant asthma after treatment showed that the red throat, shortness of breath, chest tightness, and dry mouth in the observation group were significantly different from those in the control group ( < 0.05). After investigation, follow-up, and statistics, the hospitalization time, hospitalization cost, asthma exacerbation control time, effective rate, and recurrence rate were compared between the two groups, and the differences between the two groups were statistically significant ( < 0.05).
CONCLUSION
The study on the clinical efficacy and low hospitalization cost of the self-prepared lung and asthma-restorative soup in patients with cough variant asthma significantly improved the patients' arterial oxygen saturation, acid-base value, arterial partial pressure of oxygen, and partial pressure of carbon dioxide and effectively controlled the heart rate and respiratory rate with high safety, which is worth further promotion.

INTRODUCTION
The incidence of Alzheimer's disease is on the rise, early detection of cognitive impairment of the elderly is very important. In traditional Chinese medicine, constitution is related to the susceptibility of the human body to diseases. Based on the theory of constitution of traditional Chinese medicine (TCM), the human population can be classified into 9 constitutions. However, little is known about the characteristics of medical constitution and related biomarkers in subjects with mild cognitive impairment (MCI).
METHODS
We measured the TCM Constitution of 214 subjects by using the Constitution in Chinese Medicine Questionnaire (CCMQ). MMSE and MoCA were used to assess cognitive function. The subjects were divided into mild cognitive impairment group (MCI, n = 152) and normal control group (NC, n = 62). The levels of serum Hcy and serum/urine 8-iso-PGF 2α were determined.
RESULTS
1) It was found that there was a significant difference in constitution types between MCI and NC. There were significant differences in MMSE and MoCA score, serum Hcy and serum/urine 8-iso-PGF 2a levels between the two groups. 2) In logistic regression analysis, the variables with statistical significance were TCM Constitution of Yang-Deficient, Phlegm-Dampness, Blood-Stasis and abnormal increase of Hcy (OR>1). 3) The MoCA scores had a positive correlation with the MMSE. A statistically significant inverse association was found between serum Hcy, blood and urine 8-iso-PGF 2a and scores of cognitive assessment in MCI.
CONCLUSION
Constitution types (Yang-Deficient, Phlegm-Dampness and Blood-Stasis) and abnormal serum Hcy elevation can be used as risk factors for MCI. MoCA scores can serve to detect MCI at early stage. Serum/urine 8-iso-PGF 2α has a certain relationship with MCI. Higher levels of serum/urine 8-iso-PGF 2α are more likely to be associated with MCI risk.

OBJECTIVE
To investigate the influence and possible targets of Dangua Fang on tricarboxylic acid (TCA) cycle and respiratory chain to enrich the prescription's mechanism of effective intervention on glycolipid metabolic diseases such as type 2 diabetes.
METHODS
After interventional rats were fed with high glucose and high fat diet ad libitum for 4 weeks, intraperitoneally injected streptozotocin to induce diabetic model. According to blood glucose level,28 diabetic rats were selected and continued to be fed with high glucose and high fat diet, were stratified by body weight, and divided randomly by blood glucose into Model group (was given sterile water by gastric perfusion and injected aquae pro injection intraperitoneally), Dangua group [Dangua liquor 20.5 g·kg·d by perfusion and aquae pro injection intraperitoneally], Inhibitor group [sterile water by perfusion and nicotinamide phosphoribosyl transferase (Nampt) specific blocker GEN-617 1.25 mg/kg intraperitoneally], DanInhit group (Dangua liquor and GEN-617 synchronously). Control group were continuously fed with ordinary diet. The intervention was last for 10 weeks. Body weight (BW), liver index (LI), glycosylated hemoglobin (HbA1c), TC, TG, free fatty acids (FFA), creatinine (Cr), and A-ketoglutarate (α-KG), Iso-citric acid (ICA), oxaloacetic acid (OAA) were tested. The cytochrome C oxidase (COX) and Succinate dehydrogenase (SDH) were evaluated by Colorimetry; Nampt protein, Adenosine triphosphate (ATP) synthase (ATPs), Nicotinamide adenine dinucleotide (NAD)and its reduced (NADH) in liver were measured by enzyme linked immunosorbent assay. The expressions of Nampt and mitochondrialnadhdehydrogenase-1 (mt-ND1) gene in liver was assessed by real-time polymerase chain reaction. Hepatic tissue staining was also completed.
RESULTS
The levels of BW, ICA, α-KG and Nampt-mRNA in the Model group are lower than that in the Normal group ( 0.05), conversely, liver weight, LI, TC, HbA1c, SDH and ATPs, mt-ND1-mRNA, and Nampt protein in the Model group are higher ( 0.01, 0.05). Compared with Model group, the levels of ICA, Nampt-mRNA and Nampt in Dangua group are significantly increased, and FFA obviously raised ( 0.01 and 0.05); liver weight, BW, SDH are obviously lower, and HbA1c decreased significantly ( 0.01, 0.05). TG, FFA and Nampt protein increased in the DanInhit group, TC, TG, BW obviously increased in the Inhibitor group, but SDH is decreased in both the two groups ( 0.05, 0.01). Compared with Dangua group, DanInhib group has the lower levels of ICA, mt-ND1-mRNA, Nampt-mRNA, and the higher level of BW, LI and HbA1c. In the Inhibitor group, ICA and Nampt protein decreased, BW and LI, HbA1c and TG increased ( 0.01 or 0.05). Tissue staining display that, in the model group there is obvious pathologic changes ie: fibrosis, steatosis and inflammatory cell infiltration. Lesions in the Dangua group are mild, and those of Inhibitor group are more obvious than the Model group, and DanInhit group is intermediately affected compared to Dangua group and Inhibitor group.
CONCLUSION
Dangua Fang increases the metabolic flux of TCA cycle and optimizes respiratory chain function by up-regulating Nampt expression.

Dysfunctional breathing (DB) is characterized by abnormal breathing patterns and often results from psychogenic causes in the absence of organic diseases. Although acupuncture and herbal treatments have been suggested as alternative therapies for DB, few studies have addressed the relationship between DB and pathological patterns from a diagnostic perspective. We asked 237 college students (130 men aged 21.4 ± 1.9 years; 107 women aged 21.4 ± 3.0 years) to complete the Korean version of the General Health Questionnaire-30 (K-GHQ-30) and four validated pathological pattern questionnaires regarding qi and yin deficiencies, phlegm, and cold-heat patterns. The Korean version of the Nijmegen Questionnaire was used to classify participants into DB and non-DB groups. Effects of age, gender, and DB on pathological patterns were examined using simple regression and two-way MANCOVA models. Age had an effect on all pattern scores except heat pattern scores (: 0.154-0.098). DB group showed a moderate main effect ( = 0.167) on pathological patterns, while gender showed a minimal main effect ( = 0.096); qi and yin deficiencies, phlegm, and cold-heat pattern scores in DB and female groups were higher than those in non-DB and male groups. The K-GHQ-30 scores showed significant positive correlations with the pathological pattern scores (: 0.243-0.533), indicating that disruption of pathological patterns could be associated with patients' psychological disturbance. In conclusion, these questionnaires may help to identify pathological patterns related to DB and determine individually tailored alternative therapies.
