Summary:The optimal assisted reproductive treatment strategy for infertile women with unilateral tubal obstruction remains *** investigate the role of intrauterine insemination(IUI)in the treatment of infertile women with unilateral tubal occlusion,the data of 148 couples were retrospectively collected and ***-eight infertile women with unilateral occlusion diagnosed by hysterosalpingography(HSG)were categorized as the study group and 70 others with unexplained infertility as the control *** study group was divided into a proximal occlusion subgroup and a mid-distal occlusion subgroup for further *** main outcomes,namely the clinical pregnancy rate(CPR),ongoing pregnancy rate(OPR),and live birth rate(LBR)per cycle,were *** results showed a tendency of lower CPR,OPR,and LBR in the study group than in the control group,without statistical *** investigations revealed that the unilateral proximal occlusion subgroup had similar CPR,OPR,and LBR as the control group,while the unilateral mid-distal occlusion subgroup had significantly lower CPR(5.1%vs.20.0%,P=0.035),OPR(5.1%vs.20.0%,P=0.035),and LBR(5.1%vs.20.0%,P=0.035)than the control *** conclusion,the clinical outcomes of IUI were worse in patients with unilateral tubal occlusion than in those with unexplained *** might be primarily caused by the worse outcome of patients with unilateral mid-distal tubal occlusion instead of proximal occlusion.

Objective To assess the effect of treatment with a combination of the tamoxifen citrate and testosterone undecanoate on sperm variables in men with idiopathic azoospermia or oIigozoospermia. Methods Four men with idiopathic azoospermia and 8 men with idiopathic oligozoospermia were collected in this retrospective and self control trial. All patients were treated with testosterone undecanoate of 80 mg/d and tamoxifen citrate of 20 mg/d. Sperm characteristics and pregnancy incidence were measured every month during 4 months medication. Results Tamoxifen citrate plus testosterone undecanoate treatment produced a satisfactory improvement of total sperm number, motility after 2 and 3 months whereas serum FSH, LH levels increased after 2 or 3 months. Conclusion The combination of tamoxifen citrate with testosterone undecanoate could improve significantly sperm count. The combination could be used in men with idiopathic azoospermia or serious oligozoospermia.

AIM： To examine the sensitivity and accuracy of real-time polymerase chain reaction （PCR） for the quantification of hepatitis B virus （HBV） DNA in semen. METHODS： Hepatitis B viral DNA was isolated from HBV carriers＇ semen and sera using phenol extraction method and QIAamp DNA blood mini kit （Qiagen, Germany）. HBV DNA was detected by conventional PCR and quantified by TaqMan technology-based real-time PCR （quantitative polymerase chain reaction （qPCR））. The detection threshold was 200 copies of HBV DNA for conventional PCR and 10 copies of HBV DNA for real time PCR per reaction. RESULTS： Both methods of phenol extraction and QIAamp DNA blood mini kit were suitable for isolating HBV DNA from semen. The value of the detection thresholds was 500 copies of HBV DNA per mL in the semen. The viral loads were 7.5×10^7 and 1.67×10^7 copies of HBV DNA per mL in two HBV infected patients＇ sera, while 2.14×10^5 and 3.02×10^5 copies of HBV DNA per mL in the semen. CONCLUSION： Real-time PCR is a more sensitive and accurate method to detect and quantify HBV DNA in the semen.

OBJECTIVE To evaluate the efficacy of rituximab combined with CHOP-like regimen with or without IFN in patients newly diagnosed diffuse large B-cell Non-Hodgkin＇s lymphoma （DLBCL）.METHODS From January 2003 to July 2008, 51 patients received CHOP-like chemotherapy （cyclophosphamide 750 mg/m2, epirubicin 80 mg/m2, vindesine 2.8 mg/m2 on day 1, and prednisolone 100 mg/day on day 1 to day 5）. Thirty-one patients received CHOPR-like treatment （rituximab 375 mg/m2 1 day before CHOP-like chemotherapy）. Twenty patients received CHOP-like regimen in combination with peginterferon （pegIFN）（1μg/kg on day 5） and rituximab （on day 6）.RESULTS -The CR （complete remission） rate in the CHOPR-like （with or without pegIFN） group and in the CHOP-like group was 78.4% and 45.1% （P = 0.005）, respectively. The estimated mean time of overall survival （OS） in the CHOPR-like group and CHOP- like group was 58.7 ± 2.8 and 36.4 ±3.4 months, respectively （P = 0.002）. The rates of CR and OR （overall remission） in CHOPR- like with IFN arm were 85.0% and 95.0%, and the rates of those in CHOPR-like without IFN arm were 74.2% and 87.0% （P 〉 0.05）. The estimated mean time of 4-year-PFS （progression- free survival） in CHOPR-like with IFN arm and in CHOPR-like without IFN arm was 62.9 ±3.0 months and 51.0 ± 4.6 months （P = 0.092）, respectively. In the CHOPR-like with IFN arm, no patient relapsed after achieving CR, while the estimated rate of 4-year- DFS （disease-free survival） in the patients who reached CR in the CHOPR-like without IFN arm was （63.4 ± 19.3）% （P = 0.061）. CONCLUSION Rituximab combined with CHOP-like chemotherapy improved the prognosis of DLBCL patients. The IFN may help to improve the quality and duration of response of DLBCL patients treated with rituximab and CHOP-like regimen.

目的:探讨亚硒酸钠对糖尿病肾病大鼠肾脏脂联素表达的影响及二者间的关系,从而研究亚硒酸钠和脂联素在糖尿病肾病中的作用机制。方法:通过链脲佐菌素法并给予高脂饮食诱导模拟大鼠糖尿病肾病模型,实验设空白对照组、糖尿病肾病对照组、亚硒酸钠干预组,每组10只。亚硒酸钠干预组每日给予亚硒酸钠溶液1μg/kg灌胃,其他各组给予等量盐水溶液灌胃。灌胃10周后处死大鼠,取大鼠血、尿标本测相关生化指标。快速切取小块肾皮质组织,4%戊二醛固定,制电镜切片扫描电镜观察超微结构。取肾脏组织标本制石蜡切片光镜下观察病理改变及免疫组化分析定位蛋白表达,定量PCR法检测脂联素的mRNA表达、蛋白质印迹法检测脂联素蛋白表达。结果:亚硒酸钠干预组大鼠基本状况和生化指标较糖尿病肾病对照组明显改善,光镜下亚硒酸钠干预组病理改变和电镜下超微结构较糖尿病肾病对照组明显减轻。免疫组化分析,亚硒酸钠干预组脂联素蛋白着色较糖尿病肾病对照组明显增强,且肾小管、肾小球内均有着色。亚硒酸钠干预组脂联素mRNA是空白对照组的2.043倍,糖尿病肾病对照组脂联素mRNA是空白对照组的1.373倍。亚硒酸钠干预组脂联素蛋白表达水平高于糖尿病肾病对照组及空白对照组,差异有统计学意义(P<0.05)。结论:亚硒酸钠通过抗氧化应激、增加外周组织对胰岛素的敏感性从而促进肾脏脂联素表达,表明亚硒酸钠和脂联素在延缓和防治糖尿病肾病的发生发展中可能起重要作用。

Dear Editor, Phenotypic drug discovery, which observes compound effects on physiology,has given way to targeting specific molecules, but has revived by using modern methods to find drugs based on therapeutic outcomes in disease models(Vincent et al., 2022). Osteoarthritis(OA) is a prevalent chronic joint disorder, primarily affecting knee joints, with osteoclast activation due to low-grade inflammation resulting in increased bone resorption and structural changes in the joint(Katz et al.,2021).
