Background Excessive deposition of extraceUular matrix （ECM） in the kidney is the hallmark of diabetic nephropathy. Increased matrix synthesis has been well documented but the effects of diabetes on degradative pathways, particularly in the in vivo setting. The renal protective effect of these pathways on matrix accumulation has not been fully elucidated. The present study was understaken to investigate the activity of matrix metalloproteinase-2 （MMP-2）, the expression of MMP-2 and tissue inhibitor of metalloproteinase-2 （TIMP-2） in kidney tissues of diabetic rats, and to explore the degradative pathway of type Ⅳ collagen （Ⅳ-C） and the renal protective effects of ACE inhibition- benazepril.

Mammalian target of rapamycin(m TOR) inhibitor as an attractive drug target with promising antitumor effects has been widely investigated. High quality clinical trial has been conducted in liver transplant(LT) recipients in Western countries. However, the pertinent studies in Eastern world are paucity. Therefore, we designed a clinical trial to test whether sirolimus can improve recurrence-free survival(RFS) in hepatocellular carcinoma(HCC) patients beyond the Milan criteria after LT. This is an open-labeled, single-arm, prospective, multicenter, and real-world study aiming to evaluate the clinical outcomes of early switch to sirolimus-based regimens in HCC patients after LT. Patients with a histologically proven HCC and beyond the Milan criteria will be enrolled. The initial immunosuppressant regimens are center-specifc for the frst 4-6 weeks. The following regimens integrated sirolimus into the regimens as a combination therapy with reduced calcineurin inhibitors based on the condition of patients and centers. The study is planned for 4 years in total with a 2-year enrollment period and a 2-year follow-up. We predict that sirolimus conversion regimen will provide survival benefts for patients particular in the key indicator RFS as well as better quality of life. If the trial is conducted successfully, we will have a continued monitoring over a longer follow-up time to estimate indicator of overall survival. We hope that the outcome will provide better evidence for clinical decision-making and revising treatment guidelines based on Chinese population data.

目的:探讨血管紧张素转换酶抑制剂苯那普利对糖尿病大鼠肾脏病变的保护作用及其机制。方法:24只健康雄性Wistar大鼠随机分成正常对照组(NC组,n=8)、糖尿病未治疗组(DM组,n=8)和糖尿病苯那普利治疗组(DL组,n=8)。应用链脲佐菌素(STZ)诱导糖尿病模型,造模成功后,用苯那普利10 mg/(kg.d)对DL组进行治疗性灌胃,其余2组均用等量自来水灌胃。4周后,将所有大鼠一次性处死,摘取肾脏。用明胶酶谱分析法检测肾组织基质金属蛋白酶-2(MMP-2)活性;用免疫组化法检测肾组织IV胶原(IV-C)、MMP-2、基质金属蛋白酶组织抑制因子-2(TIMP-2)蛋白的表达,并利用计算机图像分析系统进行半定量图像分析;用逆转录-聚合酶链反应测定肾组织中MMP-2、TIMP-2mRNA的表达。同时进行肾组织透射电镜检查。结果:糖尿病组与正常对照组比较,尿量、Upro、BUN、Ccr显著增高(P均<0.01),肾小球MMP-2活性、mRNA及蛋白表达均降低,而TIMP-2 mRNA及蛋白表达升高,IV-C胶原表达亦增加;苯那普利治疗组Upro、BUN、Ccr较糖尿病组均有不同程度的降低(P均<0.05),肾小球MMP-2活性、mRNA及蛋白表达升高,而TIMP-2 mRNA及蛋白表达I、V-C胶原表达均减少。结论:苯那普利对糖尿病大鼠肾功能和肾组织形态学具有保护作用,其作用机制可能与上调肾小球MMP-2的表达和下调TIMP-2的表达,提高MMP-2活性,从而减轻肾小球细胞外基质沉积有关。

We present weakly interacting massive particles(WIMPs) search results performed using two approaches of effective field theory from the China Dark Matter Experiment(CDEX), based on the data from both CDEX-1B and CDEX-10 stages. In the nonrelativistic effective field theory approach, both time-integrated and annual modulation analyses were used to set new limits for the coupling of WIMP-nucleon effective operators at 90% confidence level(C.L.) and improve over the current bounds in the low mχregion. In the chiral effective field theory approach, data from CDEX-10 were used to set an upper limit on WIMP-pion coupling at 90% C.L. We for the first time extended the limit to the m_(χ)<6 GeV/c^(2) region.

We operated a p-type point contact high purity germanium(PPCGe)detector(CDEX-1B,1.008 kg)in the China Jinping Underground Laboratory(CJPL)for 500.3 days to search for neutrinoless double beta(0νββ)decay of ^(76)Ge.A total of 504.3 kg⋅day effective exposure data was *** anti-coincidence and the multi/single-site event(MSE/SSE)discrimination methods were used to suppress the background in the energy region of interest(ROI,1989–2089 keV for this work)with a factor of 23.A background level of 0.33 counts/(keV⋅kg⋅yr)was *** lower limit on the half life of^(76)Ge 0νββdecay was constrained as T_(1/2)^(0ν)>1.0×10^(23)yr(90%C.L.),corresponding to the upper limits on the effective Majorana neutrino mass:<3.2–7.5 eV.
