AIM
The naturally fermented yak yogurt of pastoralists in the Tibetan Plateau, China, because of its unique geographical environment and the unique lifestyle of Tibetan pastoralists, is very different from other kinds of sour milk, and the microorganisms it contains are special. subsp. HFY14 (LLSL-HFY14) is a new lactic acid bacterium isolated from naturally fermented yak yogurt. The purpose of this study was to study the inhibitory effect of the bacterium on constipation.
METHODS
Constipation was induced in ICR mice with diphenoxylate, and the constipated mice were treated with LLSL-HFY14. The weight and feces of the mice were visually detected. Colonic tissues were observed on hematoxylin and eosin-stained sections. Serum indices were detected with kits. mRNA expression in the colon was determined by quantitative polymerase chain reaction assay.
RESULTS
Constipation caused weight loss, the number of defecation granules, defecation weight, fecal water content decreased, and the first black stool excretion time increased. LLSL-HFY14 alleviated these symptoms, and the effects were similar to those of lactulose (drug). The pathological examination revealed that constipation caused pathological changes in the colon, and LLSL-HFY14 effectively alleviated the disease. LLSL-HFY14 increased serum levels of motilin, gastrin, endothelin, substance P, acetylcholinesterase, and vasoactive intestinal peptide (VIP) and decreased serum levels of somatostatin in constipated mice. In addition, LLSL-HFY14 upregulated VIP, cAMP, protein kinase A, and aquaporin 3 expression in colonic tissues of constipated mice in a dose-dependent manner.
CONCLUSION
LLSL-HFY14 inhibited constipation, similar to lactulose, and has the potential to become a biological agent.

This study compares the prevention effects of Shuidouchi with different fermentation times on constipation in mice. Shuidouchi is a short-time fermented soybean product. By improving its processing technology, it can incur better biological activity and become a health food. The Shuidouchi-treated mice were evaluated using constipation-related kits, quantitative polymerase chain reaction (qPCR), and Western blot assays. After the mice were fed 72-h-fermented Shuidouchi (72-SDC) for 9 d, the defecation time to excrete the first black stool was lower than that of the control and 24-SDC and 48-SDC groups, but was much higher than that of the normal group. The gastrointestinal (GI) transit of the small intestine of the 72-SDC group was higher than that of the control and the 24-SDC and 48-SDC groups, but lower that of the normal group. Meanwhile, 72-SDC could significantly increase the levels of , endothelin-1 (ET-1), vasoactive intestinal peptide (VIP), and acetylcholinesterase (AchE) in the serum of constipated mice compared to the levels in mice in the control group. Moreover, 72-SDC could raise , stem cell factor (), glial cell-derived neurotrophic factor (), neuronal nitric oxide synthase (), and endothelial nitric oxide synthase () messenger RNA (mRNA) and protein expression levels, and reduce transient receptor potential cation channel subfamily V member 1 () and inducible nitric oxide synthase () expression levels in small-intestinal tissue compared to the levels in the control group. Meanwhile, 72-SDC also raised mRNA expression in gastric tissue and transient receptor potential ankyrin 1 () mRNA expression in colon tissue compared to the control group mice; these effects were stronger than those of 24-SDC and 48-SDC. Shuidouchi has good preventative effects on constipation and performs best when fermented for at least 72 h.

A high volume of ileostomy output in patients with extensive bowel resection can be hard to manage. This leads to extensive loss of fluids and electrolytes along with malabsorption. Medications have traditionally controlled it by delaying intestinal transit and decreasing intestinal and gastric secretion using opiates, loperamide, diphenoxylate, omeprazole, somatostatin, and octreotide. However, many patients depend on parenteral nutrition and fluid and electrolyte infusions, even with optimal drug therapy. Despite the best possible care, they may develop renal failure. Teduglutide is a glucagon-like peptide-2 (GLP-2) analog given as a daily subcutaneous injection, and it has been promising in managing short bowel syndrome. It has been effective in decreasing the dependence on parenteral nutrition. However, improving fluid and electrolyte balance can precipitate cardiac failure in some patients, especially those with borderline cardiac functions, hypertension, and thyroid disorders. This usually presents in the first few months of the initiation of teduglutide therapy and may require stopping the medication. We present the case report of an elderly female with a high-output stoma on parenteral nutrition on teduglutide. There was a significant decrease in stoma output, and parenteral nutritional support could be stopped. However, she presented with worsening dyspnea and was diagnosed with cardiac failure with an ejection fraction of 16%-20%. The baseline ejection fraction was 45%, done six months before this. Coronary angiography showed no stenosis in any vessels, and the decline in left ventricular ejection fraction and fluid overload was attributed to teduglutide therapy.

This study assessed the efficacy and mechanism of action of Yangyin Runchang decoction (YRD) in the treatment of slow-transit constipation (STC). ICR mice were randomly divided into four groups ( = 10/group) and treated with saline (normal control; NC), atropine/diphenoxylate (model control; MC; 20 mg/kg), or atropine/diphenoxylate plus low-dose YRD (L-YRD; 29.6 g/kg) or high-dose YRD (H-YRD; 59.2 g/kg). Intestinal motility was assessed by evaluating feces and the intestinal transit rate (ITR). The serum level of stem cell factor (SCF) and changes in interstitial cells of Cajal (ICCs) were also evaluated. Additionally, the expression of SCF and c-kit and the intracellular Ca concentration [Ca] were investigated. Fecal volume and ITR were greater in the L-YRD and H-YRD groups than in the MC group. The serum SCF level was lower in the MC group than in the NC group; this effect was ameliorated in the YRD-treated mice. Additionally, YRD-treated mice had more ICCs and elevated expression of c-kit and membrane-bound SCF, and YRD also increased [Ca] in isolated ICCs. YRD treatment in this STC mouse model was effective, possibly via the restoration of the SCF/c-kit pathway, increase in the ICC count, and enhancement of ICC function by increasing [Ca] .

BACKGROUND
The - (ZhiShi, ZS-) (BaiZhu, BZ) pairs are often found in herbal formulas for constipation. The volatile oils of ZS and BZ (ZBVO) have good pharmacological activity against constipation, but the mechanism for treatment of slow transit constipation (STC) remains unclear.
METHOD
A rat model using diphenoxylate tablets was constructed to investigate if transdermal administration of ZBVO would mediate intestinal microorganisms and fecal metabolites and improve STC symptoms. The regulatory effects of ZBVO at 0.15, 0.30, and 0.60 mL kg d on STC rats were assessed by measuring fecal water content, intestinal propulsion rate, histopathology, expression of gastrointestinal hormones, brain and intestinal peptides, and inflammatory factors. The changes in intestinal flora of STC rats were analyzed by 16S rRNA gene sequencing. Moreover, the untargeted fecal metabolomics analysis was performed by ultraperformance liquid chromatography quadrupole time-of-flight mass spectrometer (UPLC-Q-TOF-MS) technology.
RESULTS
The results showed that ZBVO had a modulating effect on STC by increasing the fecal water content and intestinal propulsion rate. Transdermal administration of ZBVO decreased serum levels of interleukin 6 (IL-6) and tumor necrosis factor- (TNF-) and increased the levels of gastrin (GAS) and substance P (SP). In addition, ZBVO increased 5-hydroxytryptamine (5-HT) levels and decreased vasoactive intestinal peptide (VIP) levels in colon and hippocampus tissues. The results of intestinal microbiota showed that ZBVO improved the diversity and abundance of intestinal microbiota and changed the community composition by decreasing and increasing , , and . And the feces metabolomics found that nicotinate and nicotinamide metabolism, purine metabolism, citrate cycle (TCA cycle), pyruvate metabolism, arachidonic acid metabolism, pyrimidine metabolism, and primary bile acid biosynthesis were modulated.
CONCLUSION
These findings suggest that ZBVO can alleviate STC symptoms by promoting intestinal peristalsis, increasing fecal water content, regulating gastrointestinal hormone level, reducing the inflammatory response, and regulating brain and intestinal peptides after transdermal administration. And structural changes in the intestinal microbiota are closely related to host metabolism and intestinal microbiota destroyed in STC modeling could be significantly improved by the ZBVO, which provides a reference for the development of aromatic drug macrohealth products.

Diphenoxylate-atropine (Lomotil) intoxication incidence was significantly high in the past, but seeing such cases in the present day of modern and advanced medicine, hints about the gaps in the practice of medicine. In our case, a general physician maltreated an infant for diarrhea with an adult dose of diphenoxylate-atropine (Lomotil), a Food and Drug Administration (FDA) unapproved drug, which caused labored breathing and pinpoint pupils. After being maltreated, at the time of presentation to the emergency room (ER), she was being misdiagnosed as a case of dehydration until doctors noticed miosis and reached the diagnosis of diphenoxylate-atropine (Lomotil) toxicity. Her condition completely reversed with a single dose of naloxone. Hence, this case highlights the need for basic knowledge about the dosage of drugs for different age groups, especially infants, along with the importance of adherence to the evaluation protocols for accurate management.

The effect of bisacodyl on the treatment of rats with slow transit constipation (STC) was studied. Forty-five female Wister rats were divided into control group, STC group, and STC bisacodyl group. The immunohistochemical method was used to determine interstitial cells of Cajal (ICC) and the expression of c-Kit protein. Body mass and the number of defecations were significantly decreased in the STC group compared with the control group on the 100th day after diphenoxylate administration, while dry weight of feces was significantly increased and the intestinal transit time was prolonged. There were significant differences in the number of defecations, dry weight of feces, and intestinal transit time among the three groups. The number of defecations was higher, dry weight of feces was lower, and intestinal transit time was shorter in the STC bisacodyl group compared to the STC group. In addition, ICC basement membrane dissolution occurred in the colon wall of the STC group. The connection between ICC and surrounding cells was destroyed, and the nucleus shrunken to different degrees. Moreover, c-Kit expression in the STC group was significantly lower than the control group. The connection between ICC and surrounding cells in the STC bisacodyl group was significantly stronger than the STC group, and the number of ICC and the expression of c-Kit were increased. Bisacodyl could reduce the severity of STC in rats by increasing the number of ICC and the expression of c-Kit.

Banana resistant starch (BRS) was extracted to investigate the structural properties of BRS, its effects on the gastrointestinal transit, and dejecta of normal and experimentally constipated mice. The mouse constipation model was induced by diphenoxylate administration. The BRS administered mice were divided into three groups and gavaged with 1.0, 2.0, or 4.0 g/kg body weight BRS per day. The small intestinal movement, time of the first black dejecta, dejecta granules, weight and their moisture content, body weight, and food intake of mice were studied. Results showed that the BRS particles were oval and spindly and some light cracks and pits were in the surface. The degree of crystallinity of BRS was 23.13%; the main diffraction peaks were at 2(θ) 15.14, 17.38, 20.08, and 22.51. The degree of polymerization of BRS was 81.16 and the number-average molecular weight was 13147.92 Da, as determined by the reducing terminal method. In animal experiments, BRS at the dose of 4.0 g/kg body weight per day was able to increase the gastrointestinal propulsive rate, and BRS at the doses of 2.0 and 4.0 g/kg body weight per day was found to shorten the start time of defecation by observing the first black dejecta exhaust. However, there were no influences of BRS on the dejecta moisture content, the dejecta granules and their weight, body weight, or daily food intake in mice. BRS was effective in accelerating the movement of the small intestine and in shortening the start time of defecation, but did not impact body weight and food intake. Therefore, BRS had the potential to be useful for improving intestinal motility during constipation.

Review
Following extended colon resections, it may not always be possible to perform colorectal anastomosis. The Deloyers procedure, which involves the transposition of the right colon, has been identified as a viable solution. This report aims to discuss the circumstances under which the Deloyers procedure was performed, as well as to evaluate the early and late postoperative outcomes, by reviewing cases conducted between 2010 and 2023. In a 22-year-old female patient who suffered major organ and tissue loss (with injuries to the sigmoid colon, descending colon, transverse colon, and mesentery) due to a firearm injury, the Deloyers procedure was applied during restorative surgery following initial damage control surgery. The procedure involved mobilizing the cecum and right colon, performing a cranio-caudal rotation over the ileocolic artery pedicle, followed by an appendectomy, and creating a colorectal anastomosis using circular staplers. There were no complications during the postoperative follow-ups. By the 14th postoperative day, the patient was discharged and experienced bowel movements four times a day, managed with 2.5 mg of diphenoxylate hydrochloride and 0.025 mg of atropine sulfate. At the 6-month follow-up, the frequency of bowel movements had decreased to twice daily without the need for medical treatment. Given the functional outcomes in patients after extended left colectomies, the Deloyers procedure, with its low associated morbidity, stands out as a viable option.

In clinical trials, rhubarb extract (Rb) was demonstrated to efficiently alleviate constipation. We would like to find out the underlying mechanism of rhubarb relieving constipation. However, there are few studies on the effects of rhubarb on colonic mucus secretion and constipation. The aim of this study was to investigate the effects of rhubarb on colonic mucus secretion and its underlying mechanism. The mice were randomly divided into four groups. Group I was the control group and Group II was the rhubarb control group, with Rb (24 g/kg body weight [b.w.]) administered through intragastric administration for three days. Group III mice were given diphenoxylate (20 mg/kg b.w.) for five days via gavage to induce constipation. Group IV received diphenoxylate lasting five days before undergoing Rb administration for three days. The condition of the colon was evaluated using an endoscope. Particularly, the diameter of blood vessels in the colonic mucosa expanded considerably in constipation mice along with diminishing mucus output, which was in line with the observation via scanning electron microscope (SEM) and transmission electron microscope (TEM). We also performed metagenomic analysis to reveal the microbiome related to mucin gene expression level referring to mucin secretion. In conclusion, Rb relieves constipation by rebuilding mucus homeostasis and regulating the microbiome.
