目的研究疏血通注射液联合羟苯磺酸钙胶囊治疗单纯型糖尿病视网膜病变的临床疗效。方法选取2013年10月—2015年4月在秦皇岛市第一医院眼科诊治的单纯型糖尿病视网膜病变患者81例,随机分为对照组(40例)和治疗组(41例)。两组患者均给予常规治疗,控制血糖水平。对照组患者口服羟苯磺酸钙胶囊,0.5 g/次,3次/d。治疗组患者在对照组的基础上静脉滴注疏血通注射液,6.0 mL加入250 mL生理盐水中,1次/d。两组患者均连续治疗1个月。观察两组患者临床疗效,对比两组患者治疗前后的视力和血液流变学指标变化。结果治疗后,对照组和治疗组临床总有效率分别为75.00%、95.12%,两组比较差异具有统计学意义(P0.05)。治疗后,治疗组患者视力比对照组患者明显好转,两组比较差异具有统计学意义(P0.05)。治疗后,两组患者血液流变学指标均较同组治疗前降低(P0.05);且治疗组降低程度更显著,两组比较差异有统计学意义(P0.05)。两组间不良反应发生比较差异无统计学意义。结论疏血通注射液联合羟苯磺酸钙胶囊能够有效改善单纯型糖尿病视网膜病变患者的临床症状,降低血小板的聚集性和血浆黏度,并且不良反应发生率低,具有一定的临床应用推广价值。     

核因子-κB/抑制蛋白-κB信号通路介导的激素敏感型单纯性肾病患儿病毒基因反式激活

目的研究核因子-κB(NF-κB)/抑制蛋白-κB(IκB)信号通路在激素敏感型单纯性肾病(SRSNS)患儿病毒基因反式激活中的作用。方法采用电泳迁移率改变实验、逆转录-聚合酶链反应(RT-PCR)和酶标记免疫吸附分析法(ELISA)分别测定SRSNS、肾炎性肾病、继发性肾小球疾病、毛细支气管炎和正常儿童外周血单个核细胞(PBMCs)NF-κB活性、呼吸道病毒基因和血浆病毒抗体;同时采用Western blot和ELISA分别检测SRSNS和正常儿童IκBα蛋白质表达和血浆IL-8水平。结果与SRSNS缓解期和其他组比较,SRSNS活动期组NF-κB活性明显增加。NF-κB活性与呼吸道病毒检出阳性率呈正相关趋势。SRSNS活动期血浆IL-8水平增高,且与NF-κB活性呈正相关(r=0.88 P<0.001)。SRSNS活动期患儿IκBα蛋白质明显低于SRSNS缓解期和正常儿童,IκBα蛋白质水平与NF-κB活性呈负相关(r=-0.884 P<0.05)。结论NF-κB/IκB信号通路介导的病毒基因反式激活过程,可能是呼吸道病毒触发SRSNS的主要机制之一。

Factors Influencing Outcomes after Ulnar Nerve Stability-Based Surgery for Cubital Tunnel Syndrome: A Prospective Cohort Study

PurposeSimple decompression of the ulnar nerve has outcomes similar to anterior transposition for cubital tunnel syndrome; however, there is no consensus on the proper technique for patients with an unstable ulnar nerve. We hypothesized that 1) simple decompression or anterior ulnar nerve transposition, depending on nerve stability, would be effective for cubital tunnel syndrome and that 2) there would be determining factors of the clinical outcome at two years.ResultsPreoperatively, two patients were rated as mild, another 20 as moderate, and the remaining 19 as severe according to the Dellon Scale. At 2 years after operation, mean grip/pinch strength increased significantly from 19.4/3.2 kg to 31.1/4.1 kg, respectively. Two-point discrimination improved from 6.0 mm to 3.2 mm. The DASH score improved from 31.0 to 14.5. All but one patient scored good or excellent according to the modified Bishop Scale. Correlations were found between the DASH score at two years and age, pre-operative grip strength, and two-point discrimination.ConclusionAn ulnar nerve stability-based approach to surgery selection for cubital tunnel syndrome was effective based on 2-year follow-up data. Older age, worse preoperative grip strength, and worse two-point discrimination were associated with worse outcomes at 2 years.     

Deficiency in DNA mismatch repair increases the rate of telomere shortening in normal human cells

DNA mismatch repair (MMR) is essential for genome stability and inheritance of a mutated MMR gene, most frequently MSH2 or MLH1, results in cancer predisposition known as Lynch syndrome or hereditary nonpolyposis colorectal cancer (HNPCC). Tumors that arise through MMR deficiency show instability at simple tandem repeat loci (STRs) throughout the genome, known as microsatellite instability (MSI). The STR instability is dominated by errors that accumulate during replication in the absence of effective MMR. In this study we show that there is a high level of instability within telomeric DNA with a tendency toward deletions in tumor-derived MMR defective cell lines. We downregulated MSH2 expression in a normal fibroblast cell line and isolated four clones, with differing levels of MSH2 depletion. The telomere-shortening rate was measured at the Xp/Yp, 12q, and 17p telomeres in the MSH2 depleted and three control clones. Interestingly the mean telomere-shortening rate in the clones with MSH2 depletion was significantly greater than in the control clones. This is the first demonstration that MSH2 deficiency alone can lead to accelerated telomere shortening in normal human cells.     

The nature of the characteristic cementum-like matrix deposits in the walls of simple bone cysts

Baumhoer D, Smida J, Nathrath M & Jundt G
(2011) Histopathology 59 , 390–396 The nature of the characteristic cementum‐like matrix deposits in the walls of simple bone cysts Aims: Simple bone cysts (SBC) are benign tumour‐like lesions, generally occurring in the metaphyses of long bones before skeletal maturity. Remarkably, in 10–70% of cases, a peculiar, amorphous and hypocellular matrix is found in the walls of SBCs which is usually regarded to consist of (calcified) fibrin clots in the literature. Because these deposits are strongly fuchsinophilic in routine van Gieson stains, the aim of this study was to investigate a series of SBCs using immunohistochemistry and electron microscopy. Methods and results: A comprehensive panel of antibodies against fibrin as well as collageneous and non‐collageneous proteins of bone was used, and detected substantial amounts of collagen and decorin as the main components of the investigated matrix. Electron microscopy clearly underlined the immunohistochemical results and also showed abundant fibrils with a periodic banding characteristic of collagen. Adjacent to and in between these collagen deposits runx‐2‐ and osterix‐expressing cells were detectable, most probably representing immature osteoprogenitor cells. Conclusions: Although still stated in the literature and most current textbooks, we were not able to detect any evidence of fibrin as a component of the respective matrix deposits that seem to consist predominantly of collagen and decorin.
