健康体检人群幽门螺杆菌感染与白蛋白尿的相关性CSCD

Objective To investigate the correlation between Helicobacter pylori (H.pylori) infection and albuminuria inphysical examination population. Methods It was a cross‑sectional study. All the adults who received physical examination and underwent 13C‑urea breath test at the Physical Examination Center in Tongji Hospital in 2021 were selected as the study subjects. General data (such as demographic information and past medical history) were documented. The physical measurement and blood biochemical indicators were checked too. Multivariate analysis was used to analyze the relationship between H. pylori infection and albuminuria. Results A total of 30 311 subjects were included in this analysis. There were 17 123 males and 13 188 females with an age of (44.51±12.17) years. The positive rate of H. pylori infection was 27.3%. The incidence of albuminuria in subjects with H. pylori infection was 6.7%, and it was 6.1% in the subjects without H. pylori infection (P=0.031). After adjusting for the confounding factors such as gender, age, diabetes and hypertension, H. pylori infection was independently associated with the risk of albuminuria (odds ratio (OR)=1.133, 95%CI: 1.018-1.261, P=0.022). Conclusion H. pylori infection is positively correlated with the occurrence of albuminuria in the physical examination population. © 2021 Chinese Medical Journals Publishing House Co.Ltd.     

99Tc-亚甲基二膦酸盐对胶原诱导性关节炎大鼠滑膜及软骨凋亡相关因子的影响

Objective Collagen induced arthritis (CIA) rats is an animal model of human rheuma-toid arthritis (RA). It is widely used in research of the pathogenesis and the therapeutic targets of RA. This paper was to investigate the therapeutic action of 99Tc-methylene diphosphonic acid (MDP) on CIA rats and its effects on the expression of apoptosis associated factor bcl-2 and bax in synoviocytes and articular chon-drocytes. Methods CIA rat models were carried out by subcutaneous injection with bovine collagen Ⅱ and incomplete Freud's adjuvant. Rats were divided into four groups: control group, CIA model group (the CIA rats were infused with physiological saline via tail vein daily), 99Tc-MDP group (the C1A rats were injected with 99Tc-Mi)P 0.04 μg 99Tc/kg via tail vein daily) and methotrexate (MTX) group (the CIA rats were in-jected with MTX 1 mg/kg via tail vein weekly). The signs of arthritis were evaluated by arthritis index (AI) scores. Immunohistochemistry was performed to detect the expression of bcl-2 and bax in synoviocytes and articular chondrocytes. SPSS 13.0 was used for data analysis. Results (1) The signs of arthritis, AI scores and pathological changes of arthrosynovitis in CIA rats were significantly improved by 99Tc-MDP orMTX. (2) The expression of bcl-2 and box in the synoviocytes of CIA model group [(39.30 ± 0.53) %, (27.37 ±2.45)%] was significantly increased compared with control group [(7.56 ± 1. 18)% , (6.14 ± 1.71) % ; q = 46.27, 24.57, all P < 0.001]. In the synovioeytes of 99Tc-M DP group and MTX group, the level of bcl-2 was remarkably decreased [(30.24 ± 2.09) %, (27.25 ± 3.33) %] compared with CIA model group (q = 13.20, 17.56, all P <0.001), while the level of bax was slightly increased and the ratio of bcl-2/bax was significantly decreased. (3)The expression level of bcl-2 and bax in the articular chondro-cytes of CIA model group [(20.20 ± 2.78) %, (36.40 ± 1.67) %] was significantly higher than control group [(9.91±4.09)%, (6.71 ±3.50)%; q=10.51, 37.01, allP<0.001]. Compared with CIA model group, the expression level of bcl-2 in articular chondrocytes of 99Tc-MDP group [(26. 58 ± 2. 52) %] and MTX group [(27.06 ± 1.92) %] was remarksbly increased [(24.26 ± 2.75) %, (23.53 ± 0.74) % ; q = 6.53, 7.01, all P < 0.001]. And the expression level of bax was significantly decread (q = 15.12, 16.04, all P <0. 001) and the ratio of bcl-2/bax was significantly increased. Conclusions The ab-normal expression of apoptosis associated factor bcl-2 and bax in synoviocytes and articular chondrocytes was closely related to the occurrence and progression of signs in CIA rats. 99Tc-MDP could improve the signs of arthritis, meanwhile regulate the expression of bcl-2 and bax in synoviocytes and articular ehondrocytes, suggesting that one of the therapeutic mechanisms of 99Tc-MDP might be related to stimulated synoviocytes apoptosis and reduced articular chondrocytes apoptosis.     

系统性红斑狼疮外周血单个核细胞DcR3 mRNA表达研究

目的研究凋亡相关基因诱骗受体3(DcR3)在系统性红斑狼疮患者(SLE)外周血单个核细胞(PBMCs)中的mRNA表达水平。方法应用半定量逆转录-聚合酶链反应(RT-PCR)检测38例SLE患者(21例活动期,17例缓解期)和15例正常人PBMCs中DcR3 mRNA的表达水平,分析其与狼疮活动指数(SLEDAI)的相关性。结果SLE患者PBMCs中,DcR3mRNA表达水平明显高于正常人(P<0.01),但疾病不同病期(活动期与缓解期)其表达水平无统计学差异(P>0.05);DcR3 mRNA表达与SLEDAI不相关(r=-0.024,P>0.05)。结论SLE患者PBMCs DcR3 mRNA表达增加,提示DcR3可能与SLE免疫细胞凋亡异常和免疫调节的紊乱有关,参与了SLE的发病过程。

目的:探讨自体外周血造血干细胞移植(APBSCT)治疗难治性系统性红斑狼疮(SLE)的临床疗效。方法:用APBSCT治疗4例难治性SLE。干细胞动员应用环磷酰胺(CTX)4g/m2,分两天应用和粒细胞集落刺激因子(G-CSF)5~10μg/kg·d-1;预处理方案包括CTX(50mg/kg·d-1,-6、-5、-4、-3d),抗胸腺细胞球蛋白(ATG15~20mg/kg·d-1,-2、-1、 1、 2d)。结果:4例患者均获得造血重建,中性粒细胞>0.5×109/L,血小板>20×109/L的中位数时间分别是9d,10d;SLE的临床表现明显减轻,尿蛋白减少或消失,自身抗体转阴或滴度减低,泼尼松用量<10mg/d;无移植相关死亡。结论:APBSCT治疗难治性SLE近期疗效显著,造血重建恢复迅速,安全有效,远期疗效尚需进一步观察。     

系统性红斑狼疮伴发假性肠梗阻十例分析

目的了解系统性红斑狼疮(SLE)伴发假性肠梗阻(IPO)的临床特征,提高对该病的诊治水平。方法收集武汉同济医院2001年7月至2005年7月收治随访的10例SLE伴发IPO的临床资料,按1:2比例选择20例同期收治性别、年龄相配,无IPO伴发的SLE病例对比分析。并搜寻国内、国外(仅限于英文)相关病例40例一并综述。结果10例IPO中,以IPO为首发表现的病例数、IPO合并泌尿系统损害及治疗后稳定病例数分别为1、5和4例,综述文献三者比例分别为46%,64%和46%。与不伴有IPO的单纯SLE病例相比,伴发IPO者其外周血白细胞数相对较高(8.1±5.2vs4.0±1.8,P<0.05),而SLE疾病活动指数(SLEDAI)评分则较低(6.1±2.2vs9.6±1.8,P<0.01),其他病情观察指标差异均无统计学意义。结论IPO可为SLE的首发表现,但往往也是SLE病程中的一种并发症,它常与泌尿系统的病变相关联。激素和免疫抑制剂能够迅速改善病人的临床症状和预后。
