OBJECTIVE To study the safety of Shuangshu decoction in rats and its efficacy in improving functional dyspepsia （FD） in rats. METHODS In safety test， 40 rats were divided into blank control group， Shuangshu decoction low-dose， medium- dose and high-dose groups [108， 216， 324 g/（kg·d）， calculated by raw medicine， the same applies below]； they were given relevant medicine intragastrically， for continuous 14 days. The mortality and toxic reactions of rats were recorded， and the organ indexes of the liver， kidney， spleen， lung and heart of rats were calculated； the pathological morphological changes in the liver， kidney， spleen， lung， heart， stomach， duodenum， and colon were observed to evaluate the acute toxicity of Shuangshu decoction. Another 40 rats were grouped and administered in the same way for 30 consecutive days. The mortality and toxic reactions of the rats were recorded， and the corresponding organ indexes were calculated. The pathological morphological changes in the corresponding organs were observed， and blood routine and serum biochemical indicators were measured， in order to assess the subacute toxicity of Shuangshu decoction. In pharmacodynamic experiments: 50 rats were divided into blank control group， model group， and Shuangshu decoction low-， medium-， and high-dose groups （9.45， 18.9， 37.8 g/kg）， with 10 rats in each group. Except for blank control group， rats in all other groups were used to establish the FD rat model by subcutaneous injection of loperamide （3.5 mg/kg）. Rats in each group were administered the corresponding drug solution/normal saline intragastrically， once a day， for 14 consecutive days. After the last medication， fecal moisture content， intestinal propulsion rate， gastric emptying rate and serum level of motilin were all detected， and interstitial cell of Cajal （ICC） ultrastructure of rats was observed in colon tissue. RESULTS The safety experiments showed that no death occurred in each dose group， and no significant difference was found in organ coefficient， routine blood and serum biological index， compared to blank control group （P＞0.05）； no abnormality was found in organ appearance and pathological sections. The results of the pharmacodynamic experiments showed that， compared with the blank control group， the fecal moisture content， gastric emptying rate， intestinal propulsion rate， and serum motilin levels in the model group were significantly decreased （P＜0.05）； in the colonic tissue， the mitochondria in the ICC exhibited severe swelling with the disappearance of cristae， and the endoplasmic reticulum was dilated. Compared with model group， the rats in Shuangshu decoction high-dose group showed significant increases in the above quantitative indicators （P＜ 0.05）； additionally， there was a large number of mitochondria in the ICC of the colonic tissue， with clear cristae and regular arrangement. CONCLUSIONS Shuangshu decoction is safe and has a beneficial improving effect on FD rats； its mechanism of action may be related to the regulation of gastrointestinal hormone expression to promote gastric emptying and intestinal propulsion， as well as the repair of mitochondrial structure in ICCs to restore gastrointestinal function.

Objective:To investigate the prevalence of infertility and the factors affecting it in women of reproductive age in Qinghai Province.Methods:From July to December 2024, a multi-stage stratified cluster random sampling approach was used to recruit women aged 20-49 years in 10 districts across 8 cities in Qinghai Province for a questionnaire survey assessing the prevalence of infertility. Univariate and multivariate binary logistic regression analyses were then performed to identify factors associated with infertility in Qinghai Province.Results:A total of 3 925 questionnaires were distributed, with 3 837 valid responses ultimately collected. Preliminary screening identified 581 infertility cases, yielding an infertility rate of approximately 15.1%. Among these, 170 cases were primary infertility and 411 were secondary infertility, accounting for 29.26% and 70.74% of infertility cases, respectively. The highest infertility rate was observed in Yushu City, Yushu Prefecture, at 26.1% (71/272), followed by Chengxi District, Xining City at 25.3% (174/688). The lowest infertility rate was recorded in Delingha City, Haixi Prefecture, at only 2.9% (9/311). Univariate analysis revealed that household registration status ( P<0.001), age ( P=0.016), age at marriage ( P=0.001), highest educational attainment ( P<0.001), per capita annual income ( P=0.001), body mass index (BMI, P=0.005), altitude ( P<0.001), age at menarche ( P=0.011), menstrual regularity ( P<0.001), menstrual cycle ( P=0.001), menstrual duration ( P<0.001), presence of blood clots ( P<0.001),whether the women smoking ( P=0.008), whether the women staying up late ( P=0.022), and whether the husband staying up late ( P<0.001) were independent factors for infertility. Multivariate binary logistic regression analysis revealed that non-agricultural household registration ( OR=1.637, 95% CI: 1.304-2.054, P<0.001), BMI≥24.0 kg/m2 ( OR=1.326, 95% CI: 1.077-1.632, P=0.008), age at menarche >14 years ( OR=1.405, 95% CI: 1.158-1.705, P=0.001), irregular menstrual cycles ( OR=1.512, 95% CI: 1.127-2.029, P=0.006), menstrual cycle <21 d ( OR=1.572, 95% CI: 1.237-1.998, P<0.001), menstrual duration <7 d ( OR=2.080, 95% CI: 1.529-2.831, P<0.001), and smoking ( OR=2.359, 95% CI: 1.056-5.271, P=0.036) were independent risk factors for infertility. Age and altitude were not independent risk factors for infertility in Qinghai Province. Conclusion:The prevalence of infertility in Qinghai Province is approximately 15.1%. Non-agricultural household registration, BMI≥24.0 kg/m2, age at menarche >14 years, irregular menstrual cycles, menstrual cycle <21 d, menstrual duration <7 d, and smoking are factors influencing infertility, while high altitude does not increase the risk of infertility among women in Qinghai Province.

Objective:To explore the clinical efficacy of Wenshen Chushi Decoction combined with low intensity pulsed ultra-sound(LIPUS)on erectile dysfunction(ED)caused by renal deficiency and phlegm-dampness syndrome.Methods:One hundred and twenty ED patients were included from the Department of Andrology in the First Hospital of Hunan University of Traditional Chinese Medicine.The patients in control group were treated with Wenshen Chushi Decoction.While the patients in observation group were trea-ted with Wenshen Chushi Decoction combined with LIPUS for 8 consecutive weeks.After the treatment,the efficacy was evaluated using the International Index of Erectile Function-5(IIEF-5)score,Penile Flow Index(PFI),Traditional Chinese Medicine Syndrome Score,Self-Rating Depression Scale(SDS)score,and Self-Rating Anxiety Scale(SAS)score.Safety was also observed.And the ef-ficacy was followed up 4 weeks after the end of treatment.Results:Fifty-seven cases were enrolled into control group finally with 55 cases in the treatment group.After the treatment,all the patients in both of groups showed an improvement in IIEF-5 scores(P＜0.01).Compared with the control group(19.09±2.22),the IIEF-5 score in observation group(20.42±2.39)increased signifi-cantly(P＜0.01).After the treatment,the scores of PFI,TCM syndrome and SDS in both groups decreased(P＜0.01,P＜0.05,P＜0.01).Compared with the control group([3.77±1.21],[9.91±1.71]and[39.88±2.63]points),the observation group([2.92±1.08],[4.78±1.45],and[34.51±2.09]points)showed a more significant decrease(P＜0.01).There was no significant difference in total effective rate between the two groups(P＞0.05).During follow-up,the IIEF-5 scores of both groups of patients were higher than those before(P＜0.05,P＜0.01),and the observation group score was higher than that in the control group([17.15±3.37]vs[13.63±1.96],P＜0.01).No adverse reaction and abnormality of indicators occurred in both of two groups.Conclusion:Wenshen Chushi Decoction has a significant therapeutic effect on ED caused by renal deficiency and phlegm-dampness syndrome.It can not only improve the quality of erection,but also improve the physical and mental symptoms associated with ED,which makes therapeutic effect lasting longer.

OBJECTIVE To investigate the effect and potential mechanism of Ziyin Mingmu Formula in treating age-related mac-ular degeneration(AMD)by combining network pharmacology with animal model validation.METHODS Active ingredients of Ziyin Mingmu Formula were obtained from the TCMSP and BATMAN databases,and their targets were searched using the PharmMapper da-tabase.AMD disease targets were identified using the GeneCards,DrugBank,OMIM,and TTD databases.Venny analysis was per-formed to identify the intersection of active ingredient and disease targets.A protein-protein interaction(PPI)network was constructed using the String database,and core targets were screened using Cytoscape 3.9.0 software.KEGG pathway enrichment analysis was per-formed using the DAVID database.Molecular docking of key active ingredients with core targets was performed using Autodock software.A laser-induced mouse choroidal neovascularization(CNV)model was used.Optical coherence tomography angiography(OCTA)was used to assess CNV area in vivo,immunofluorescence staining was used to assess CNV area on choroidal flat mounts,and Western blot analysis was used to examine the expression of proteins involved in the vascular endothelial growth factor(VEGF)pathway.RESULTS Network pharmacology analysis identified 221 active ingredients in the Ziyin Mingmu Formula.PPI analysis i-dentified 29 core targets,including SRC,protein kinase B(AKT1),mitogen-activated protein kinase 1(MAPK1),and heat shock protein 90α family class A member 1(HSP90AA1).KEGG analysis revealed that the VEGF signaling pathway was the most highly en-riched.Molecular docking revealed that the core targets SRC,AKT1,MAPK1,and HSP90AA1 had good binding affinity with the main active ingredients,diosmetin,catechin,vestitol,and licochalcone A.Animal experiments showed that the Ziyin Mingmu Formula significantly reduced CNV area in model mice,downregulated VEGF protein expression,decreased VEGFR2,p38,and ERK1/2 pro-tein phosphorylation levels,and inhibited the VEGF signaling pathway.CONCLUSION Ziyin Mingmu Formula may inhibit CNV for-mation by regulating the VEGF signaling pathway.

Objective:This article introduces a novel technique for totally laparoscopic, right thoracic approach, esophagojejunostomy for digestive tract reconstruction.Methods:A retrospective analysis was conducted on the clinical data of patients with adenocarcinoma of the esophagogastric junction who successfully underwent totally laparoscopic esophagojejunostomy via the right thoracic approach at Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, between February 2022 and March 2022.The surgical procedure was performed as follows:(1)Following total laparoscopic resection of the gastric tumor and lymph node dissection, the specimen was transected distal to the tumor margin. The specimen was then placed into a retrieval bag and extracted through the umbilical observation port.(2)Dissection was continued through the esophageal hiatus to mobilize the esophagus. The tumor-bearing tissue, along with the esophagus, was delivered into the thoracic cavity via the esophageal hiatus.(3)The jejunum was transected 20 cm distal to the ligament of Treitz. The distal Jejunum was mobilized for 15-20 cm and subsequently delivered into the thoracic cavity through the esophageal hiatus.(4)A Roux-en-Y jejunojejunostomy was constructed 45-50 cm distal to the cut end of the distal jejunal limb; the mesenteric defect was closed, and the duodenal stump was reinforced.(5)The patient was repositioned into the left lateral decubitus position. Port placement was established as follows: the observation port at the 7th intercostal space (ICS) in the right midaxillary line, the main operating port at the 4th ICS in the anterior axillary line, and the assistant operating port at the 9th ICS in the scapular line.(6)The main operating port incision was enlarged. Using a purse-string instrument, the esophagus was clamped and transected at least 5 cm proximal to the upper tumor margin, and the specimen was removed. (7)The distal jejunum was delivered into the thoracic cavity via the esophageal hiatus. Under total laparoscopic visualization, esophagojejunostomy was completed.Results:Both patients who underwent totally laparoscopic esophagojejunostomy via the right thoracic cavity successfully completed the procedure without conversion to laparotomy, unplanned reoperation, or any intraoperative/postoperative complications. The patients recovered well postoperatively, with no evidence of abdominal or thoracic hemorrhage. Postoperative computed tomography (CT) scans of the chest and abdomen confirmed the absence of anastomotic leakage or other related complications.Conclusions:The esophagojejunostomy was performed totally laparoscopically via the right thoracic cavity. This approach overcomes the drawback of significant trauma associated with open surgery while ensuring safe esophageal resection margins and thorough lymph node dissection. This technique offers advantages including minimal invasiveness, accelerated postoperative recovery, and a reduced incidence of reflux esophagitis. To our knowledge, no similar method of digestive tract reconstruction has been reported in the literature. Its novelty and clinical potential may offer new therapeutic options for patients with Siewert type II adenocarcinoma of the esophagogastric junction (AEG).

Objective To elucidate the effects and mechanisms of Biejiajian pill(BJJP)-containing serum on the malignant biological behaviors of hepatocellular carcinoma Huh7 cells.Methods This research knocked down CKLF-like MARVEL transmembrane domain containing 6(CMTM6)expression using a CMTM6-specific small interfering RNA(siRNA).Healthy Sprague-Dawley rats were used to prepare normal rat serum and low-(0.55 g/kg),medium-(1.1 g/kg),and high-(2.2 g/kg)BJJP-containing.Huh7 cells were cultured with normal fetal bovine serum(BC),normal rat serum(NC),and low-,medium-,and high-dose BJJP serum(LBJJP,MBJJP,and HBJJP,respectively).BJJP-containing serum and si-CMTM6 were applied to Huh7 cancer cells,and the proliferation,migration,and invasion abilities were evaluated by CCK-8 and Transwell assays,respectively.Protein expression levels of proliferating cell nuclear antigen(PCNA),epithelial-mesenchymal transition(EMT)markers,and CMTM6 were detected by Western blot.Results CMTM6 knockdown significantly reduced the mRNA and protein expression level of CMTM6 in Huh7 cells(P＜0.05).There were no significant differences between the BC and NC groups in terms of cell proliferation,migration,invasion,expression levels of PCNA,EMT markers,and CMTM6(all P＞0.05).BJJP-containing serum markedly inhibited Huh7 cell proliferation,migration,and invasion(P＜0.05),downregulated PCNA,CMTM6,N-cadherin,and Vimentin expression,and upregulated E-cadherin compared with the NC group(all P＜0.05).CMTM6 knockdown suppressed malignant behaviors,with reduced PCNA,Vimentin,and N-cadherin and elevated E-cadherin expression(all P＜0.05).Conclusions BJJP-containing serum can significantly inhibit Huh7 cell growth,invasion,migration,and EMT progression,potentially mediated via CMTM6 suppression.
