Objective To explore the molecular mechanism of Xiaojin Pills in the treatment of breast cancer using an integrated network pharmacology and experimental verification.Methods The chemical components and potential targets of Xiaojin Pills were obtained from TCMSP,TCM-ID,ETCM and SwissTargetPrediction databases.Breast cancer related targets were collected from GeneCards,OMIM and KEGG databases.The overlapped targets were imported into STRING database to analysis a protein-protein interaction(PPI).The key targets of PPI networks were screened based on node topology parameter values through Cytoscape 3.8.0.DAVID database was used to analyze the GO and KEGG pathway enrichment to build drug-chemical components-key targets-signaling pathway network.The breast cancer cell lines MDA-MB-231 and SK-BR-3 were used to study the effects of Xiaojin Pills extract on cell apoptosis,migration and invasion,and to verify the key pathway obtained by enrichment analysis.Results Totally 181 chemical components in Xiaojin Pills were obtained,including quercetin,myricetin,pinocembrin and β-sitosterol.615 potential targets were identified for the anti-breast cancer effects of Xiaojin Pills.After overlapping,170 key targets against breast cancer were identified based on the topological analysis,which included SRC,ERK1/2,AKT1,EGFR,etc.KEGG analysis enriched pathways including pathways in cancer,MAPK signaling pathway,endocrine resistance,PI3K-AKT signaling pathway,EGFR tyrosine kinase inhibitor resistance,apoptosis,and HIF-1 signaling pathway,which may play important roles in the therapeutic effects of Xiaojin Pills against breast cancer.GO enrichment was involved in protein phosphorylation,inflammatory response,negative regulation of apoptosis,and positive regulation of ERK1 and ERK2 cascades.Cell experiments showed that Xiaojin Pills further induced mitochondria-dependent apoptosis by inhibiting the activation of MAPK and PI3K-AKT pathways.At the same time,the expressions of ZO-1 and β-catenin increased,and the epithelial-mesenchymal transformation process was reversed to inhibit the metastasis of breast cancer cells.Conclusion The key targets and signaling pathways of Xiaojin Pills in the treatment of breast cancer are studied through network pharmacology combined with in vitro experiments,which provided a basis for further study of its pharmacodynamic material basis,mechanism of action and clinical application.

Objective:To compare the short-term efficacy and the safety of microwave ablation (MWA) and radiofrequency ablation (RFA) in the treatment of benign thyroid nodules (BTNs).Methods:This prospective randomized controlled trial, performed from December 2019 to September 2021, included 36 patients with solid or predominantly solid BTNs who met the eligibility criteria and provided written informed consent at the Nanjing sub-center (Affiliated Hospital of Integrated Traditional Chinese and Western Medicine, Nanjing University of Chinese Medicine). Patients were assigned to either the MWA group or the RFA group (18 patients in each group) at a ratio of 1∶1 using a block randomization design and allocation concealment using sealed envelope randomization. The independent-sample t-test and χ2 test were used to compare the volume reduction rates (VRRs), effective rates (VRRs≥50%), cosmetic scores, and complication rates at 1, 3, and 6 months after treatment between the two groups. Results:The clinical characteristics of the two groups of patients were comparable. After ablation, the nodule volume was significantly reduced in both groups. At 1, 3, and 6 months, there was no significant difference in the volume between the two groups (all P>0.05). At 3 months, the RFA group had a larger VRRs than that in the MWA group (62.08%±12.46% vs. 46.90%±23.16%, t=-2.45, P=0.021). However, at 1 and 6 months, no statistical significance was observed (both P>0.05). No significant difference was observed in the effective rates at the last follow-up (14/18 vs. 18/18, P=0.104). However, the RFA group had a lower cosmetic score than that in the MWA group (1.78±0.43 vs. 2.17±0.51, t=-2.47, P=0.019). There was no statistically significant difference in the complication rates between the two groups (all P>0.05). Conclusions:Both MWA and RFA were effective and safe treatments for BTNs, with no significant differences in short-term efficacy and safety. In addition, the RFA group showed slightly more favorable outcomes than the MWA group in terms of cosmetic improvement.

Objective To observe the efficacy of ruiyun procedure for hemorrhoids(RPH)combined with conformal suture in the treatment of severe prolapsed hemorrhoids.Methods Seventy-eight patients with severe prolapsed hemorrhoids admitted to the First People's Hospital of Xuzhou from June 2021 to August 2022 were selected and divided into observation group and control group according to random number table method,with 39 cases in each group.Patients in observation group were treated with RPH combined with conformal suture,and patients in control group were treated with external peeling and internal ligation.Operation duration,intraoperative blood loss,postoperative complications,wound healing time,anal function and overall satisfaction were compared between two groups.Results The intraoperative blood loss in observation group was significantly less than that in control group,hospital stay was significantly shorter than that in control group(P<0.05).Postoperative pain,bleeding,anal edema and the formation of anal skin pad in observation group were significantly better than those in control group(P<0.05).At 12 weeks after surgery,Wexner anal incontinence scores in both groups were significantly lower than before surgery(P<0.05),and the Wexner anal incontinence score in observation group was significantly lower than that in control group(P<0.05).The cure rate of observation group was significantly higher than that of control group(92.31%vs.74.36%,χ2=55.46,P=0.03),and the overall satisfaction with treatment was significantly higher than that of control group(χ2=58.57,P=0.02).Conclusion RPH combined with conformal suture is effective in treatment of severe prolapsed hemorrhoids,which can reduce the pain of patients,shorten the length of hospital stay,reduce complications,and improve the comfort and satisfaction of patients.

Background::Intrauterine valvuloplasty is an innovative therapy, which promotes ventricular growth and function in some congenital heart diseases (CHDs). The technique remains challenging and can only be performed in a few centers. This study aimed to assess the feasibility and mid-term outcomes of fetal cardiac intervention (FCI) in fetuses with critical CHD in an experienced tertiary center.Methods::Five fetal aortic valvuloplasty (FAV) or fetal pulmonary valvuloplasty (FPV) procedures were performed in our fetal heart center between August 2018 and May 2022. Technical success was defined as crossing the aortic or pulmonary valve and balloon inflation, followed by evidence of increased blood flow across the valve and/or new regurgitation. Follow-up clinical records and echocardiography were obtained during the prenatal and postnatal periods.Results::Five fetuses received FAV or FPV, including critical aortic stenosis ( n = 2) and pulmonary atresia with intact ventricular septum ( n = 3). The mean maternal age was 33.0 ± 2.6 years. The median gestational age (GA) at diagnosis was 24 weeks (range, 22-26 weeks). The median GA at intervention was 29 weeks (range, 28-32 weeks). All five cases underwent successful or partially successful procedures. One patient had pulmonary valve perforation without balloon dilation. No procedure-related deaths or significant complications occurred. However, one neonatal death occurred due to heart and renal failure. The median follow-up period was 29.5 months (range, 8.0-48.0 months). The four surviving patients had achieved biventricular circulation, exhibited improved valve, and ventricular development at the last follow-up visit. Conclusion::Intrauterine FCI could be performed safely with good prognosis in critical CHD.

Objective:To study the distribution and antibiotics resistance of the main pathogens of neonatal purulent meningitis in different regions of China.Methods:A retrospective descriptive clinical epidemiological study was conducted in children with neonatal purulent meningitis which admitted to 18 tertiary hospitals in different regions of China between January 2015 to December 2019. The test results of blood and cerebrospinal fluid, and drug sensitivity test results of the main pathogens were collected. The distributions of pathogenic bacteria in children with neonatal purulent meningitis in preterm and term infants, early and late onset infants, in Zhejiang Province and other regions outside Zhejiang Province, and in Wenzhou region and other regions of Zhejiang Province were analyzed. The chi-square test was used for statistical analysis.Results:A total of 210 neonatal purulent meningitis cases were collected. The common pathogens were Escherichia coli ( E. coli)(41.4%(87/210)) and Streptococcus agalactiae ( S. agalactiae)(27.1%(57/210)). The proportion of Gram-negative bacteria in preterm infants (77.6%(45/58)) with neonatal purulent meningitis was higher than that in term infants (47.4%(72/152)), and the difference was statistically significant ( χ2=15.54, P=0.001). There were no significant differences in the constituent ratios of E. coli (36.5%(31/85) vs 44.8%(56/125)) and S. agalactiae (24.7%(21/85) vs 28.8%(36/125)) between early onset and late onset cases (both P>0.05). The most common pathogen was E. coli in different regions, with 46.7%(64/137) in Zhejiang Province and 31.5%(23/73) in other regions outside Zhejiang Province. In Zhejiang Province, S. agalactiae was detected in 49 out of 137 cases (35.8%), which was significantly higher than other regions outside Zhejiang Province (11.0%(8/73)). The proportions of Klebsiella pneumoniae, and coagulase-negative Staphylococcus in other regions outside Zhejiang Province (17.8%(13/73) and 16.4%(12/73)) were both higher than those in Zhejiang Province (2.9%(4/137) and 5.1%(7/137)). The differences were all statistically significant ( χ2=14.82, 12.26 and 7.43, respectively, all P<0.05). The proportion of Gram-positive bacteria in Wenzhou City (60.8%(31/51)) was higher than that in other regions in Zhejiang Province (38.4%(33/86)), and the difference was statistically significant ( χ2=6.46, P=0.011). E. coli was sensitive to meropenem (0/45), and 74.4%(32/43) of them were resistant to ampicillin. E. coli had different degrees of resistance to other common cephalosporins, among which, cefotaxime had the highest resistance rate of 41.8%(23/55), followed by ceftriaxone (32.4%(23/71)). S. agalactiae was sensitive to penicillin, vancomycin and linezolid. Conclusions:The composition ratios of pathogenic bacteria of neonatal purulent meningitis are different in different regions of China. The most common pathogen is E. coli, which is sensitive to meropenem, while it has different degrees of resistance to other common cephalosporins, especially to cefotaxime.

Background/Aims: Epstein-Barr virus-associated gastric cancers (EBVaGCs) have unique molecular and clinicopathological characteristics. The cyclic GMP-AMP synthase-stimulator of interferon genes (STING) pathway is recently recognized as the critical innate immunity against pathogens and tumors. STING is also a master regulator in the cancer-immunity cycle and targeting STING could synergize with existing immune-checkpoint therapies. However, the role of STING in GC, especially in EBVaGC, and its correlation with programmed death-ligand 1 (PD-L1) remain largely unclear. Methods: We collected 78 cases of EBVaGCs and 210 cases of EBV-negative GC (EBVnGC) from a total of 1,443 cases of GC analyzed by EBV-encoded small RNA in situ hybridization. We investigated STING and PD-L1 expression and their concomitant prognostic value in EBVaGCs and EBVnGCs using tissue microarray and immunohistochemistry. The effects of STING and PD-L1 expression on the overall survival of patients with EBVaGC or EBVnGC were assessed by univariate and multivariate analysis. Results: We found that both STING and PD-L1 exhibited significantly higher expression in the EBVaGCs than that in the EBVnGCs. The expression of STING was positively correlated with that of PD-L1 in EBVaGCs. Simultaneous negative expression of STING and PD-L1, and positive expression of STING were independent prognostic risk factors for EBVaGC and EBVnGC, respectively. Conclusions This is the first prognostic retrospective study of STING and PD-L1 expression and the prognosis among EBVaGC and EBVnGC. The expression and prognostic value of STING and PD-L1 are different in the two types of GCs. STING and PD-L1 are promising prognostic biomarkers and therapeutic targets for EBVaGC and EBVnGC.

Objective To study the clinical features and risk factors of acute pulmonary reperfusion injury after operation in neonates with severe pulmonary stenosis or pulmonary atresia.Method From February 2014 to February 2018,a retrospective analysis was performed in patients with critical pulmonary stenosis or pulmonary atresia who received percutaneous balloon pulmonary valvuloplasty (PBPV) in the neonatal intensive care unit of our hospital.Clinical characteristics,perioperative cardiac structure,hemodynamic data and biochemical results were collected.The neonates were assigned into injury group if they had acute lung reperfusion injury,and non-injury group if not.The risk factors of acute lung reperfusion injury were analyzed using multi-variate Logistic regression model.Result A total of 32 patients (24 prenatal diagnosis and 8 postnatal diagnosis) with severe pulmonary stenosis or pulmonary atresia with intact ventricular septum were enrolled.The main manifestations were dyspnea and cyanosis.Intravenous prostaglandin E was administered to keep the ductus arteriosus open.The age of operation ranged from 1 to 52 days and the median age was 7.5 days.Postoperative acute lung reperfusion injury occurred in 7 cases (21.9％).Preoperative and intraoperative pulmonary valve annulus diameter,balloon diameter,preoperative hemoglobin,hematocrit and blood albumin were significantly lower in the injury group.The operation duration,total length of hospital stay and postoperative duration were longer than in the non-injury group,the differences were statistically significant (P ＜ 0.05).Multi-variate Logistic regression analysis showed that the diameter of pulmonary valve annulus (OR =5.814,95％CI 1.106 ～30.568),preoperative blood albumin (OR =1.361,95％ CI 1.063 ～ 1.742),and hematocrit (OR =1.173,95％ CI 1.010 ～ 1.363) were risk factors of acute lung reperfusion injury,with statistically significant differences (P ＜ 0.05).Conclusion Acute lung reperfusion injury is one of the common complications after the operation of severe pulmonary stenosis or pulmonary atresia.The severity of pulmonary valve annulus stenosis,preoperative hematocrit and blood albumin level may be the risk factors of postoperative acute lung reperfusion injury.

Objective To investigate the changes of sex hormone levels in male patients with metabolic syndrome and its clinical significance.Methods From January 2012 to January 2016,a total of 186 male patients in the Integrated Chinese and Western Medicine Hospital Affliated to Nanjing University of Traditional Chinese Medicine were enrolled,and they were divided into MS group(n =112) and non-MS group(n =74) according to the definition of adult metabolic syndrome.All of patients were measured blood pressure,blood glucose,blood lipid,pancreas islet function and sex hormone,such as testosterone (TT),sex hormone binding globuli (SHBG),progestin (P),prolactin (PRL),luteinizing hormone (LH),follicle-stimulating hormone (FSH),estradiol (E2),dehydroepiandrosterone (DHEA).The sex hormone level and the correlation of components of metabolic syndrome between the two groups were compared.Results Compared with those in the non-MS group,the BMI,blood pressure,lipid levels in the MS group were significantly increased,the fasting blood glucose,HbA1c,FINS HOMA-IR in the MS group were significantly increased[(8.74 ± 1.93) mmol/L vs.(7.49 ± 2.39) mmol/L,(10.86 ±2.45)％ vs.(9.09 ±2.61)％,(13.62 ± 6.37) mIU/L vs.(6.88 ±5.05)mIU/L,(5.53 ±2.28) vs.(3.24 ±1.35),t=5.76,4.49,2.47,2.81,all P ＜ 0.05],and TT,SHBG in the MS group significantly decreased [(18.95 ± 9.51) nmol/L vs.(10.10 ±2.97)nmol/L,(35.86±27.93)nmol/Lvs.(25.56±19.90)nmol/L,t=3.18,5.46,allP＜0.05].Conclusion MS was associated with hypogonadism,and the more components of metabolic syndrome,the more hypogonadism.

Objective To investigate the prevalence of iron deficiency(ID)and iron deficiency anemia (IDA) in pregnant women in urban areas of China. Methods The study was a national cross-sectional survey conducted from September 19th, 2016 to November 20th, 2016. According to the classification of the National Bureau of Statistics, all survey sites were set up in 6 regions of the country. Pregnant women were continuously selected using multistage stratified sampling. A total of 12 403 pregnant women were collected and examined for serum ferritin and hemoglobin levels. Results The median serum ferritin level during pregnancy was 20.60 μg/L(11.78-36.98 μg/L), the hemoglobin level was(118±12)g/L. With the progress of pregnancy, the levels of serum ferritin and hemoglobin decreased gradually. The median serum ferritin levels in the first, second trimester and third trimester were 54.30 μg/L(34.48-94.01 μg/L), 28.60 μg/L(16.40-50.52 μg/L), and 16.70 μg/L(10.20-27.00 μg/L)respectively(P<0.01). The mean hemoglobin levels were(127 ± 10)g/L,(119 ± 11)g/L and(117 ± 11)g/L respectively(P<0.01). The prevalence of ID in urban pregnant women was 48.16%(5 973/12 403), and IDA prevalence was 13.87% (1 720/12 403). The prevalence of IDA in the first, second trimester and third trimester were 1.96% (20/1 019), 8.40%(293/3 487)and 17.82%(1 407/7 897), respectively(P<0.01). The prevalence of standardized ID and IDA were significantly different in various regions of China(P<0.01). The standardized prevalence of ID were relatively higher in East China and Northeast China, 57.37% and 53.41% respectively, while it was the lowest in Southwest China, 30.51%. The standardized prevalence of IDA in South Central, Northwest, and East China were relatively high, 21.30%, 16.97% and 17.53% respectively, and the standardized prevalence of IDA in Southwest China was the lowest, 5.44%,the differents in various regions were significant(all P<0.01). Conclusion The current phenomenon of ID and IDA in pregnant women is still very common,and nutrition and health care during pregnancy should be strengthened.
