ABSTRACT
ABSTRACT Purpose: To compare the effectiveness and safety of marketed oral drugs for overactive bladder based on a systematic review and network meta-analysis approach. Methods: Pubmed, Embase, Web of Science, and the Cochrane Register of Clinical Trials databases were systematically searched. The search time frame was from database creation to June 2, 2022. Randomized controlled double-blind trials of oral medication for overactive bladder were screened against the protocol's entry criteria. Trials were evaluated for quality using the Cochrane Risk of Bias Assessment Tool, and data were statistically analyzed using Stata 16.0 software. Result: A total of 60 randomized controlled double-blind clinical trials were included involving 50,333 subjects. Solifenacin 10mg was the most effective in mean daily micturitions and incontinence episodes, solifenacin 5/10mg in mean daily urinary urgency episodes and nocturia episodes, fesoterodine 8mg in urgency incontinence episodes/d and oxybutynin 5mg in voided volume/micturition. In terms of safety, solifenacin 5mg, ER-tolterodine 4mg, mirabegron, vibegron and ER-oxybutynin 10mg all showed a better incidence of dry mouth, fesoterodine 4mg, ER-oxybutynin 10mg, tolterodine 2mg, and vibegron in the incidence of constipation. Compared to placebo, imidafenacin 0.1mg showed a significantly increased incidence in hypertension, solifenacin 10mg in urinary tract infection, fesoterodine 4/8mg and darifenacin 15mg in headache. Conclusion: Solifenacin showed better efficacy. For safety, most anticholinergic drugs were more likely to cause dry mouth and constipation, lower doses were better tolerated. The choice of drugs should be tailored to the patient's specific situation to find the best balance between efficacy and safety.
ABSTRACT
@# Objective To investigate the drug resistance of Enterobacter cloacae isolated from blood samples in 75 member units of the Bacterial Drug Resistance Monitoring Network in Hebei, 2016- 2021, so as to provide a basis for rational drug use in clinic. Methods WHONET 5.6 software was used to retrospectively analyze drug susceptibility of Enterobacter cloacae isolated from 32 secondary hospitals and 43 tertiary hospitals. SPSS19.0 software was used for statistical analysis. Results After removing the duplicate strains, 1 225 strains of E. cloacae were isolated from blood samples of 75 hospitals during 6 years, including 157 strains from secondary hospitals and 1 068 strains from tertiary hospitals. In this study, the resistance of Enterobacter cloacae to 16 kinds of antibiotics was analyzed. The drug resistance rates to cefuroxime (52.4%-67.8%), piperacillin (27.4%-31.2%), ceftazidime (27.8%-35.5%), ceftriaxone (29.5%-45.0%), aztreonam (22.2%-32.3%), cotrimoxazole (21.6%-28.7%) were higher; the resistance rates to amikacin and tobramycin were lower than 15.0%. The resistance rates to imipenem and meropenem were 3.6%-12.3% and 5.1%-11.4%, respectively. The resistance rate to ciprofloxacin in tertiary hospitals was 22.4%, and the resistance rate to cotrimoxazole was 23.9%. Except for these two antimicrobials, the resistance rates to other antimicrobial drugs in tertiary hospitals were higher than that in secondary hospitals. A total of 121 carbapenem-resistant Enterobacter cloacae strains were detected in the past 6 years, with an increasing detection rate (χ2trend=6.305, P=0.012). Conclusions Enterobacter cloacae has great differences in antimicrobial resistance to different antibiotics, and is sensitive to carbapenems. The drug resistance in tertiary hospitals is generally higher than that in secondary hospitals. Drug resistance monitoring and drug resistance mechanism research should be strengthened to better guide clinical drug use and curb the rise of drug resistance.
ABSTRACT
@#[摘 要] 目的：探讨结直肠癌（CRC）组织中磷酸甘油酸变位酶1（PGAM1）的表达及其与患者预后的关系，研究PGAM1对CRC细胞增殖、迁移和侵袭的影响。方法：选择2003年3月至2008年11月间在天津医科大学肿瘤医院手术切除的30例CRC患者的肿瘤组织标本及临床资料，采用免疫组织化学染色法检测CRC组织中PGAM1蛋白的表达，分析PGAM1表达与患者临床病理特征的关系，Kaplan-Meier生存分析法比较PGAM1高表达与低表达患者的OS、PFS来评价PGAM1表达与患者预后的关系。利用RNA干扰技术分别将si-PGAM1及si-NC质粒转染至HCT-116和SW480细胞，WB法检测转染细胞中PGAM1蛋白的表达水平，CCK-8、Transwell实验分别检测敲低PGAM1对CRC细胞增殖、迁移和侵袭的影响。结果：30例CRC组织中PGAM1阳性染色定位于CRC细胞的细胞质，其中33.3%（10/30例）呈高表达。虽然PGAM1高表达与CRC患者年龄、性别、组织学类型、肿瘤大小、淋巴结转移、远处转移及临床TNM分期无关（均P>0.05），但是PGAM1高表达与低表达患者相比其OS、PFS显著缩短。在CRC细胞中敲低PGAM1后，细胞的增殖、迁移和侵袭能力均显著降低（均P<0.05）。结论：CRC组织中PGAM1呈高表达，PGAM1高表达的患者预后较差；敲低PGAM1后细胞的增殖、迁移及侵袭能力均显著降低，提示PGAM1可能是CRC患者预后的生物标志物。
ABSTRACT
Trust in automation plays a leading role in human-automation interaction. As there lack of scales measuring trust in automation in China, the purpose of this study was to adapt the trust between People and Automation Scale (TPAS) into Chinese and to demonstrate its psychometric properties among Chinese adults. A total of 310 Chinese adults were randomly selected as sample 1, and 508 Chinese adults as sample 2. Results of the item analysis revealed that each item had a good quality, and the exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) suggested that the two-factor model with 12 items was the best fitting model. In addition, the TPAS was positively correlated with Interpersonal Trust Scale (ITS), proving good evidence based on relations to other variables to support the TPAS. In sum, the study suggested that the Chinese version of the TPAS could be used as an effective tool to assess trust in automation in the Chinese context.

Abstract Purpose Patients with diabetes are vulnerable to myocardial I/R (ischaemia/reperfusion) injury, but are not responsive to IPO (ischaemic post-conditioning). We hypothesized that decreased cardiac Adiponectin (APN) is responsible for the loss of diabetic heart sensitivity to IPO cardioprotecton. Methods Diabetic rats were subjected to I/R injury (30 min of LAD occlusion followed by 120 min of reperfusion). Myocardial infarct area was determined by TTC staining. Cardiac function was monitored by a microcatheter. ANP, 15-F2t-isoprostane, nitrotyrosine and MDA were measured by assay kits. Levels of p-Akt, total-Akt and GAPDH were determined by Western Blot. Results Diabetic rats subjected to myocardial IR exhibited severe myocardial infarction and oxidative stress injury, lower APN in the plasma and cardiac p-Akt expression ( P <0.05). IPO significantly attenuated myocardial injury and up-regulated plasma APN content and cardiac p-Akt expression in non-diabetic rats but not in diabetic rats. Linear correlation analysis showed that the expression of adiponectin was positively correlated with p-Akt and negatively correlated with myocardial infarction area ( P <0.01). Conclusion Protective effect of IPO was tightly correlated with the expression of adiponectin, exacerbation of I/R injury and ineffectiveness of IPO was partially due to the decline of adiponectin and inactivation of Akt in diabetes mellitus.

@# Objective: To investigate the effect of myeloid-derived suppressor cells (MDSCs) from mice bearing breast cancer on the function of normal B cells. Methods:ABABL/c mouse 4T1 breast cancer model was established. The spleen MDSCs of tumor-bearing mouse and normal mouse spleen B cells were sorted by magnetic beads, and the sorted MDSCs and B cells were co-incubated. Flow cytometry was used to test the effect of MDSCs on the expressions of B cell surface molecules, including PD-1, PD-L1, CTLA-4, CCR6, CD62L and MHCⅡ; ELISA assay was used to detect the secretion of IgA, IgM and IgG by B cells; BrdU kit was used to detect B cell proliferation; andAnnexin V/PI staining was used to detect B cell apoptosis. B cells in the co-culture system were again sorted by magnetic beads and were then co-cultured with T cells; BrdU kit was used to detect T cell proliferation, and Annexin V/PI was used to detect T cell apoptosis. Results: Compared with B cell control group, the expression of PD-L1 on B cells in B+MDSC group was increased (P<0.01), while the expressions of PD-1, CTLA-4, CCR6, CD62L and MHC Ⅱ were all decreased (all P<0.01); The IgA, IgM and IgG secreted by B cells were significantly increased (all P<0.01); the proliferation of B cells was increased (P<0.01) and the apoptosis was decreased (P<0.01). Compared with the T cell control group, the proliferation of T cells in the B+MDSC (1:5) +T group was significantly reduced (P<0.01); however, there was no significant difference in T cell apoptosis. Conclusion: MDSCs from breast cancer bearing mice promotes B cell proliferation and inhibits B cell apoptosis, and the MDSC-induced B cells can inhibit T cell proliferation.
ABSTRACT
Esophageal cancer is a common malignant tumor,whose pathogenesis and prognosis factors are not fully understood.This study aimed to discover the gene clusters that have similar functions and can be used to predict the prognosis of esophageal cancer.The matched microarray and RNA sequencing data of 185 patients with esophageal cancer were downloaded from The Cancer Genome Atlas (TCGA),and gene co-expression networks were built without distinguishing between squamous carcinoma and adenocarcinoma.The result showed that 12 modules were associated with one or more survival data such as recurrence status,recurrence time,vital status or vital time.Furthemaore,survival analysis showed that 5 out of the 12 modules were related to progression-free survival (PFS) or overall survival (OS).As the most important module,the midnight blue module with 82 genes was related to PFS,apart from the patient age,tumor grade,primary treatment success,and duration of smoking and tumor histological type.Gene ontology enrichment analysis revealed that "glycoprotein binding" was the top enriched function of midnight blue module genes.Additionally,the blue module was the exclusive gene clusters related to OS.Platelet activating factor receptor (PTAFR) and feline Gardner-Rasheed (FGR) were the top hub genes in both modeling datasets and the STRING protein interaction database.In conclusion,our study provides novel insights into the prognosis-associated genes and screens out candidate biomarkers for esophageal cancer.
ABSTRACT
<p><b>OBJECTIVES</b>To investigate the prevalence of hepatitis B virus (HBV) genotypes and the association with hepatocellular carcinoma (HCC) or basal core promoter (BCP) mutation in Qidong, China.</p><p><b>METHODS</b>The whole genome of HBV or X gene sequences were obtained from serum samples of HBV infected patients by using PCR and direct sequencing methods. Phylogenetic tree was constructed to determine the genotypes or subgenotypes of HBV.</p><p><b>RESULTS</b>According to the phylogenetic tree constructed from full-length sequence of HBV, genotype C2 was predominant in Qidong area. It was prevalent in 44 out of the 48 cases (91.7%), whereas genotype B2 only existed in 4 cases (8.3%). No other genotypes or recombinant types were found in Qidong patients. The result of genotyping based on X gene sequence confirmed the above observation. In a total of 182 samples, 169 (92.9%) showed genotype C2 and 10 (5.5%) showed genotype B2. There were 3 (1.6%) patients showed a coinfection with C2 and B2. The infection rate of genotype C in Qidong was significantly higher than that in neighboring city Shanghai (chi(2) = 12.252, P less than 0.01). There was no significant difference of genotype distribution between HCC and chronic hepatitis groups (P is more than 0.05). The frequency of T1762/A1764 double mutation in genotype C2 (70.3%) was significantly higher than that in genotype B2 (30.8%, P less than 0.05). The other two types of point mutation which also occurred in BCP, i.e. T1766 and A1768, were only seen in genotype C2.</p><p><b>CONCLUSION</b>(1) Genotype C2 is the predominant genotype in Qidong, China. (2) There is no association between genotype C and HCC in Qidong. (3) Genotype C has a higher prevalence of BCP mutation than genotype B.</p>
