ObjectiveTo observe the effectiveness and safety of Jiuzihuichun decoction combined with spleen- strengthening moxibustion in patients with asthenospermia infertility with spleen-kidney deficiency pattern. MethodsA total of 82 patients with asthenospermia of spleen-kidney deficiency pattern in Shanghai Seventh People's Hospital were included. The patients were randomly divided into an observation group and a control group， with 41 patients in each group. The control group received oral administration of WuziYanzong pills combined with spleen-strengthening moxibustion. The dosage of Wuzi Yanzong pills was 1 bag each time， and it was taken twice a day. The spleen-strengthening moxibustion was carried out once a week. The observation group， on the other hand， took Jiuzi Huichun decoction orally combined with spleen-strengthening moxibustion. The Jiuzi Huichun Decoction was taken 200 mL each time， twice a day， with one dose in the morning and one in the evening. The spleen-strengthening moxibustion for the observation group was also performed once a week. The treatment course for both groups was 12 weeks， and they were followed up for an additional 12 weeks. During the treatment process，12 cases were either lost to follow-up or excluded. Eventually， 70 cases were available for evaluation，with 35 cases in the control group and 35 cases in the observation group. The pregnancy status of the patients' spouse within 6 months was recorded. The traditional Chinese medicine （TCM） syndrome scores of spleen-kidney deficiency pattern before and after treatment were evaluated. The semen volume，semen routine parameters，normal sperm morphology，sperm DNA fragmentation index，seminal plasma fructose，seminal plasma acid phosphatase， and seminal plasma α-glucosidase levels of the two groups were detected before and after treatment. In addition， the safety indicators related to liver and kidney functions of the two groups were detected before and after treatment. ResultsDuring the 6-month observation period， when compared with the situation before treatment in their respective groups，the semen volume of the observation group and the control group increased. In contrast， the sperm concentration，sperm motility，proportion of a+b-grade sperm，normal sperm morphology，seminal plasma fructose，seminal plasma acid phosphatase，seminal plasma α-Glucosidase，the proportion of a-grade sperm，linear sperm motility，linear sperm concentration， and linear sperm count all increased significantly（P<0.05）. At the same time， the sperm DNA fragmentation index and the TCM syndrome scores of the spleen-kidney deficiency pattern decreased significantly（P<0.05）. When the observation group was compared with the control group after treatment， the clinical efficacy of the observation group was better（Z=-2.276，P<0.05）. The pregnancy rate of the observation group's spouses was 14.3%，which was higher than the 2.9% of the control group. The sperm motility， the proportion of a+b-grade sperm，seminal plasma fructose，the proportion of a-grade sperm，normal sperm morphology，α-glucosidase， and linear sperm motility in the observation group were higher than those in the control group （P<0.05）. Moreover， the sperm DNA fragmentation index and the TCM syndrome scores of spleen-kidney deficiency pattern in the observation group were lower than those in the control group （P<0.01）. No serious adverse reactions occurred in the two groups，and no abnormalities were found in the safety indicators after treatment. ConclusionJiuzi Huichun decoction combined with spleen-strengthening moxibustion can enhance sperm viability and sperm concentration. It can also improve the TCM-related symptoms of asthenospermia of spleen-kidney deficiency pattern and sperm morphology. Additionally， it can reduce the sperm DNA fragmentation index and regulate the level of seminal plasma bioenzyme in patients with male asthenospermia infertility of spleen-kidney deficiency pattern. Therefore， it is worthy of further promotion and application in clinical practice.

Objective To explore the association between oral microbiota and esophageal carcinogenesis. Methods A case-control study design was employed. A total of 309 subjects were recruited, consisting of 159 healthy controls, 32 cases of esophageal basal cell hyperplasia, 32 cases of low-grade intraepithelial neoplasia, 14 cases of high-grade intraepithelial neoplasia, and 72 cases of esophageal squamous cell carcinoma. Tongue swab samples were collected for 16S rRNA sequencing. The α-diversity and β-diversity of the microbiota were analyzed, and the characteristics of the microbial communities at different stages of esophageal carcinogenesis were compared. The strength of the association was expressed by odds ratio (OR) and 95% confidence interval (CI). Results α-diversity analysis indicated significant differences in the observed species number (Sobs) index across various stages of esophageal cancer progression (P<0.001). After adjusting for confounding factors such as age, gender, smoking, and alcohol consumption, the Simpson index was positively correlated with carcinogenesis (P=0.006). β-diversity analysis revealed differences in microbiota structure among the groups. After ordered multinomial logistic regression analysis and adjustment for multiple confounding factors, the relative abundance of Peptostreptococcus (OR: 2.06, 95%CI: 1.22–3.60), Patescibacteria (OR: 1.31, 95%CI: 1.04–1.67), Capnocytophaga (OR: 1.24, 95%CI: 1.05–1.54), and Bacteroidota (OR: 1.02, 95%CI: 1.00–1.05) was positively correlated with carcinogenesis. The relative abundance of Stomatobaculum (OR: 0.57, 95%CI: 0.30–1.00) and Actinobacteriota (OR: 0.95, 95%CI: 0.92–0.98) was negatively correlated with carcinogenesis. Conclusion Specific oral microbiotas are significantly associated with esophageal carcinogenesis, and synergistic or antagonistic interactions may be observed among the microbiota.

Objective:To analyze and discuss the clinical significance of preoperative planning and guidance based on three-dimensional reconstruction of perigastric vessels in precision surgery for gastric cancer.Methods:A prospective study was conducted to analyze the data of 50 patients with gastric cancer who received surgical treatment in Jiangyin People′s Hospital from December 2020 to December 2022, including 35 males and 15 females, aged from 38 to 79 years old, with an average age of 66.3 years old. All patients were divided into control group ( n=25) and experimental group ( n=25) according to random number table method. Both groups underwent enhanced multi-slice spiral CT scan of the chest, abdomen and pelvis before surgery. The experimental group underwent 3D reconstruction based on CT data for preoperative planning and guidance, while the control group did not undergo 3D reconstruction. Patients in both groups received radical surgery for gastric cancer. Operation time, intraoperative blood loss, total postoperative drainage volume, postoperative hospital stay, number of lymph node dissection and postoperative complications were compared between the two groups. The statistical software SPSS27.0 was used to obtain the relevant data analysis results. Results:The intraoperative blood loss, total drainage volume and postoperative hospital stay of the experimental group were lower than those of the control group( P<0.05). The operative time, number of lymph node dissection and postoperative complications of the experimental group were not significantly different from those of the control group( P>0.05). Conclusions:Preoperative three-dimensional reconstruction of gastric perivascular with CT data can provide better preoperative evaluation, surgical planning and intraoperative guidance, reduce intraoperative accidental vascular injury, blood loss, total postoperative drainage and postoperative hospital stay. It has positive clinical application value to complete accurate radical resection of gastric cancer.

Objective:To investigate effect of vitexin on macrophage polarization and its impact on tumor growth in a mouse model of prostate cancer.Methods:C57BL/6J male mice were used to establish RM-1 prostate cancer xenograft model.Mice were ran-domly divided into model group,vitexin-low,medium and high doses groups(40,80,160 mg/kg),and cisplatin group as positive control.After continuous administration for 16 days,mice were euthanized and tumor mass was measured.HE staining was performed to observe tumor morphology.Immunohistochemistry was used to detect Ki67 positive rate.Flow cytometry was conducted to measure expressions of CD86+CD11b and CD206+CD11b in tumor-associated macrophages.CCK8 assay was performed to assess cytotoxic effect of vitexin on RAW264.7 macrophages to determine suitable concentrations.RT-qPCR was used to measure mRNA expressions of M2 macrophage markers,including arginase-1(ARG-1),Fizz1 and Ym1.Results:Vitexin inhibited tumor volume and weight,induced tumor tissue necrosis,suppressed Ki67 protein expression,increased expression of CD86+CD11b+M1 macrophages,and inhibited CD206+CD11b+M2 macrophage expression in mouse tumor tissues in vivo.Vitexin at concentrations of 10～20 μmol/L showed no cyto-toxicity on RAW264.7 macrophages in vitro,and promoted expression of iNOS in IL-4-induced M2 macrophages while inhibiting CD206 expression,as well as suppressed mRNA expressions of ARG-1,Fizz1 and Ym1.Conclusion:Vitexin effectively inhibits tumor growth in a mouse model of prostate cancer,possibly by regulating M2 macrophages towards an M1 phenotype and exerting immunomodulatory effects.

Objective:To observe any effect of percutaneous tibial nerve stimulation (PTNS) combined with electro-acupuncture on detrusor overactivity after a spinal cord injury.Methods:Forty spinal cord injury survivors with neurogenic detrusor overactivity were randomly assigned to a control group or an observation group, each of 20. Both groups received routine bladder training and electro-acupuncture modulating 3 sacral spinal nerves. The observation group also received 20 minutes of bilateral PTNS five times a week for 8 weeks. The frequency was 10Hz with a pulse width of 200μs. Before and after the treatment, both groups′ urination frequency, incontinence and average daily urine volume were assessed using a urodynamics analyzer, bladder diaries and an incontinence quality of life questionnaire (I-QOL).Results:After treatment, the average involuntary detrusor contraction volume (IDCV), maximum detrusor pressure at filling time (P det·max), bladder compliance (BC), residual volume and the TL value of the electromyogram of the urethral sphincter (LgTLR) had all improved significantly in both groups. The 1st IDCV, BC and LgTLR of the observation group were then significantly better than in the control group, on average, with the average P det·max and residual volume significantly lower than in the control group. The average daily single urine output and I-QOL score of both groups had increased significantly, while the average daily urination frequency and frequency of urinary incontinence had decreased significantly. Both were again significantly better in the observation group. Conclusion:Combining percutaneous electrical stimulation of the tibial nerves with electro-acupuncture can effectively inhibit detrusor overactivity after a spinal cord injury, reducing urinary incontinence.

Objective:To investigate the prognostic value of myocardial flow reserve (MFR) measured by SPECT myocardial blood flow (MBF) quantitative technique in patients with intermediate stenoses of coronary arteries.Methods:From September 2019 to May 2021, patients with intermediate stenoses (50% to 80%) identified by invasive coronary angiography in Fuwai Hospital, Chinese Academy of Medical Sciences, Fuwai Center China Cardiovascular Hospital, and TEDA International Cardiovascular Hospital were prospectively included. All patients underwent a one-day rest/stress SPECT myocardial perfusion imaging (MPI) and SPECT MBF quantification. The radioactivity distribution of each segment of the MPI bullseye polar maps were obtained according to the standard 5-point method to obtain the summed stress score (SSS) and the summed difference score (SDS) to determine the existence of abnormality. ROC curve analysis was used to obtain the optimal prognostic cut-off value for MFR. The primary endpoint was defined as cardiovascular endpoint events. Survival and prognostic analyses were conducted by Kaplan-Meier method and Cox proportional hazard models. The difference of AUCs was analyzed by Delong test.Results:A total of 314 patients (194 males, 120 females; age (59.4±8.6) years) were enrolled. Over a median follow-up duration of 754 (range: 628-914) d, 54 patients had endpoint events. ROC curve showed that the prediction ability of MFR was significantly better than that of conventional MPI (AUCs: 0.713 and 0.512; z=3.76, P<0.001). The optimal prognostic cut-off value for MFR to predict endpoint events in patients with intermediate stenoses was 2.04. Cox multivariate analysis showed that MFR (hazard ratio ( HR)=0.434, 95% CI: 0.282-0.669, P<0.001) was an independent predictor of endpoint events in patients with intermediate stenoses. Kaplan-Meier survival analysis showed that the prevalence of endpoint events in patients with MFR≤2.04 was significantly higher than that in patients with MFR>2.04 (25.4%(43/169) vs 7.6%(11/145); χ2=21.27, P<0.001). Conclusion:The MFR measured by SPECT MBF quantitative technique has an independent predictive value for cardiovascular endpoint events in patients with intermediate stenoses.

OBJECTIVE To investigate the role of solute carrier family 1 member 4(SLC1A4) in platinum-based chemotherapy resistance in ovarian cancer. METHODS The expression of SLC1A4 in ovarian cancer or platinum-resistant ovarian cancer was analyzed by GEO and TCGA database analysis tools. The expression of SLC1A4 in platinum-treated ovarian cancer cell lines was analyzed by GEO database. The relation of SLC1A4 expression and overall survival(OS) or progression free survival(PFS) in ovarian cancer patients were analyzed by Kaplan Meier-plotter. Correlation between SLC1A4 gene effect and sensitivity to chemotherapeutic agents in ovarian cancer was analyzed through DepMap platform. Low expression of SLC1A4 mediates cisplatin resistance in ovarian cancer cells as verified by flow cytometry and tumor cell clone colony formation assays; prediction of microRNAs(miRNA) targeting SLC1A4 was conducted using TargetScan then validated their correlation in TCGA ovarian cancer samples. Used COREMINE tool to analyze the biological processes of SLC1A4 mediating chemoresistance in ovarian cancer. RESULTS SLC1A4 was significantly reduced in ovarian cancer patients and platinum-resistant ovarian cancer(P<0.05) and significantly correlated with OS and PFS in ovarian cancer patients(P<0.05). SLC1A4 expression was increased in ovarian cancer cells with platinum treatment. The genetic effect of SLC1A4 on ovarian cancer was positively correlated with platinum drug sensitivity. Overexpression of SLC1A4 increased cisplatin-induced apoptosis and reduced tumor cell colony formation in ovarian cancer cells. Hsa-let-7c-5p was targeted to SLC1A4 and significantly negatively correlated in samples from drug-resistant ovarian cancer patients. CONCLUSION Low expression of SLC1A4 mediates platinum drug resistance in ovarian cancer and is potentially associated with hsa-let-7c-5p regulation.

Objective:To investigate the correlation of human epidermal growth receptor 2 (HER2) with clinicopathological characteristics and its postoperative prognostic value in patients with gastric cancer.Methods:The clinicopathological data of 543 patients with gastric cancer who underwent open radical gastrectomy were retrospectively analyzed in the Gastrointestinal Surgery Department of Jiangyin People′s Hospital Affiliated to Southeast University from June 2011 to December 2016, including 404 males and 139 females, aged from 26 to 84 years old. According to the results of HER2 immunohistochemical staining, gastric cancer patients were divided into HER2 0+ group ( n=427), HER2 1+ group ( n=56), HER2 2+ group ( n=29) and HER2 3+ group ( n=31), and the differences in clinicopathological indicators of the four groups were compared. Furthermore, HER2 0+ and 1+ gastric cancer patients were classified as HER2-negative group( n=26), and HER2 3+ as HER2-positive group( n=26). Propensity score matching method was used to balance the basic data variables related to prognosis of the two groups, and Kaplan-Meier method was used for survival analysis. Cox risk regression model was used to analyze the risk factors associated with postoperative survival in patients with HER2-positive gastric cancer. Results:The overexpression rate of HER2 in gastric cancer patients was 5.7% (31/543). The expression level of HER2 was significantly correlated with gender ( χ2=8.30, P=0.040), tumor longitudinal location ( χ2=22.86, P=0.029) and histological differentiation ( χ2=13.27, P=0.004). There was no significant correlation between median survival time and HER2 expression level( χ2=5.44, P=0.142). After propensity score matching, the median survival time of gastric cancer in the HER2-positive group was 23 months. Univariate and multivariate analysis showed that ABO blood group ( HR: 1.619, 95% CI: 1.081-2.423, P=0.019) was an independent risk factor for prognosis of HER2-positive gastric cancer. Conclusion:The expression of HER2 is higher in men, cardia fundus and high and medium differentiated gastric adenocarcinoma, but there is no significant correlation between the expression level of HER2 and the median survival time of gastric cancer. ABO blood group may be an independent risk factor for the survival of HER2-positive gastric cancer.
