Objective To systematically evaluate the diagnostic value of TERC gene on high-grade squamous intraepithelial lesion (HGSIL) of the cervix. Methods Such databases as PubMed, EMbase, and The Cochrane Library were searched by March 31, 2012. According to the inclusion and exclusion criteria, the literature was screened and the data were extracted. The quality was evaluated in accordance with the quality assessment tool for diagnostic accuracy studies (QUADAS) and the meta-analysis was conducted by using Meta-Disc 1.4 software. Result A total of 12 studies involving 7 894 cases were included. The results of meta-analysis showed that the sensitivity, specificity and diagnostic odds ratios of TERC gene on HGSIL of cervix were 0.81 (95%CI 0.80 to 0.82), 0.83 (95%CI 0.82 to 0.84), 17.37 (95%CI 8.77 to 34.41), respectively. Conclusions The diagnostic value of TERC gene were medium in diagnosing HGSIL of the cervix alone, and it can be used as an optional method in clinical diagnosis.
Objective To investigate the association of central obesity (Waist-to-Hip Ratio) and carotid intima-media thickness (IMT) in Han, Uygur and Kazak female adults in Xinjiang. Methods Four-stage stratified cluster random sampling was used to select adult samples aged over 35 years in different districts in Xinjiang, and then a study was conducted using a questionnaire, physical exams (including blood pressure, height, weight, waist length, and hip length) and lab biochemical tests, while IMT was measured by ultrasound. According to WHR, the people were divided into two groups (WHR≥0.9 group and WHRlt;0.9 group). Results 14 618 cases had been surveyed, including 7 294 female adults (Han: 2 793 cases; Uygur: 2 490 cases; and Kazak: 2 011 cases). Among the same nationality, the WHR≥0.9 group had higher levels of systolic pressure, diastolic pressure, urea nitrogen, fasting blood-glucose, triglyceride and total cholesterol than the WHRlt;0.9 group, with significant differences (P=0.000). The two groups were the same in creatinine, high-density lipoprotein cholesterol and low density lipoprotein with no significant differences (Pgt;0.05). Among all people, the WHR≥0.9 group had slightly thicker IMT than the WHRlt;0.9 group (P=0.17). Among the Han nationality, the two groups were the same in IMT (P=0.23). Uygur’s IMT and Kazak’s IMT in the WHR≥0.9 group were thicker than that in the WHRlt;0.9 group (P=0.00). Among different populations, in the WHR≥0.9 group, Kazak’s IMT was the thickest, while Uygur’s IMT was the thinner, with significant differences (P=0.00). Within the WHR≥0.9 group, in different age groups, Kazak’s IMT was the thickest; except in the group of aged over 75 years, there were significant differences among other subgroups, the Han group, and the Uygur group (all Plt;0.05). The result of logistic regression showed that, WHR≥0.9 was an independent risk factor of IMT thickening among the three groups. Conclusion WHR increase is positively associated with IMT among the three nationalities. Also, WHR≥0.9 was an independent risk factor of IMT in all the three nationalities.
Objective To systematically evaluate effectiveness and safety of nerve block therapy for neck pain. Methods Databases including CENTRAL, PubMed, Ovid, ISI, EBSCO, CBM and CNKI were searched from the date of their establishment to November 2011, and relevant references were also retrieved manually to collect both domestic and abroad randomized controlled trials (RCTs) about nerve block therapy for neck pain. According to the inclusion and exclusion criteria, two researchers independently screened literature, extracted data, and assessed the quality of the included studies. Then the meta-analysis was conducted using RevMan 5.0 software. Results A total of 10 studies involving 625 participants were included. The results of qualitative analysis showed that: a) The short-term effectiveness of the nerve block therapy group was markedly superior to the placebo group, the cognitive therapy group and the transcutaneous electric nerve stimulation (TENS) group; and b) The short-term effectiveness of the combined nerve block therapy was markedly superior to the single nerve block therapy. The results of meta-analysis demonstrated that: a) There was no significant difference between the greater occipital nerve (GON) block group and the C2/3 nerve block group in neither short-term (SMD=−0.13, 95%CI −0.58 to 0.32, P=0.58) nor medium-term effectiveness (SMD=−0.01, 95%CI −0.46 to 0.44, P=0.98); and b): There was no significant difference between the injection with steroids group and the injection without steroids group in both short-term (SMD=0.16, 95%CI −0.13 to 0.44, P=0.28) and long-term effectiveness (SMD=0.27, 95%CI −0.02 to 0.55, P=0.07). Conclusion Current evidence shows nerve block therapy for neck pain is safe and especially good in short-term effectiveness. The combined nerve block therapy is probably more effective, but the effectiveness is not obviously improved by injection with or without steroids, and by different block methods. Due to the limitation of quality, quantity and total sample size of the included studies, this conclusion still needs to be proved by conducting more high quality and large scale studies.
Objective To compare the effects of arthroplasty with that of intenal fixation for displaced femoral neck fractures in the elderly. Methods We searched for all randomized controlled trials and quasi-randomized controlled trials of hip arthroplasty versus internal fixation for displaced femoral neck fractures in the elderly by electronically searching MEDLINE( 1966 to September, 2006),EMbase(1966 to September, 2006), Cochrane Library( Issue 4 2006), CBM( up to September, 2006) and CNKI (September, 2006) and handsearching grey literatures. The quality of the trials was assessed and meta-analyses were conducted using The Cochrane Collaboration’s RevMan 4.2.8 software. The quality of the trials was assessed. And meta-analysis was conducted by using RevMan4.2.8 software. Results A total of 228 papers were retrieved, but only 15 published randomized controlled trials involving a total of 2 254 patients were suitable for inclusion in the review. Based on the meta-analyses, hip arthroplasty showed obvious advantages over internal fixation in terms of the incidences of major complications after 2 years (RR 0.15 ; 95%CI 0.09 to 0.23) and after 5 years (RR 0.18 ; 95%CI 0.11 to 0.30) as well as re-operation rate (RR0.12 ; 95%CI 0.08 to 0.18) after 2 years, and after 5 years (RR0.11 ; 95%CI 0.06 to 0.22), there was an advantage to performing hip asthroplasty. After one year, the mortality was the same in both groups with RR 1.05 and 95%CI 0.89 to 1.23. Conclusion There is an evidence base to support arthroplasty as a treatment for displaced femoral neck fractures in the elderly. Arthroplasty can not only decrease the rate of re-operation, but can also reduce the incidence of complications, with similar one-year mortality when compared to internal fixation.
目的 探讨阿托伐他汀钙对颈动脉粥样硬化患者血管内皮的保护作用。 方法 选取2010年10月－2011年8月颈动脉粥样硬化患者80例，随机分为治疗组和对照组。对照组给予阿司匹林肠溶片0.1 g，早饭后口服1次；治疗组在此基础上给予阿托伐他汀钙20 mg，每晚口服1次，10个月为1个疗程。分别在治疗前后进行颈动脉彩色多普勒超声检测颈动脉中膜厚度及颈动脉粥样硬化斑块面积，测定甘油三酯（TG）、总胆固醇（TC）、低密度脂蛋白胆固醇（LDL-C）、高密度脂蛋白胆固醇（HDL-C）、一氧化氮（NO）、血管内皮素-1（ET-1）水平。两组患者在1个疗程治疗结束后停药12周，测定TG、TCH、LDL-C、HDL-C、NO、ET-1水平。 结果 与治疗前比较，治疗组患者的TG、TC、LDL-C、ET-1水平显著降低，HDL-C、NO水平显著升高（P＜0.01）。颈动脉中膜厚度和颈动脉粥样硬化斑块面积明显变小（P＜0.05）。对照组无明显变化。治疗组停药12周后与停药时比较，TG、TC、LDL-C、ET-1水平显著升高，HDL-C、NO水平明显降低（P ＜0.05）。对照组无明显变化。 结论 阿托伐他汀钙能显著改善颈动脉粥样硬化斑块患者的血管内皮功能、血脂水平，稳定颈动脉粥样硬化斑块，促进斑块逆转，且需要长期坚持服用。
目的 探讨阳性激发点推拿联合依托芬那酯凝胶治疗对颈肩背肌筋膜炎的临床疗效。 方法 收集2011年2月－10月确诊为颈肩背肌炎的患者52例，采用随机对照试验,其中26例采用依托芬那酯凝胶加阳性激发点推拿（治疗组），另外26例采用传统推拿进行常规推拿手法治疗（对照组）。对两组患者5次治疗后的疗效率、每次治疗后的疼痛面谱量化评分、7个月后随访疼痛复发率等疗效进行对照分析。 结果 治疗组和对照组经连续治疗5次后，总有效率分别为96.15%和80.77%，差异均有统计学意义（P＜0.05）；疼痛面谱量化评分治疗组在第一次治疗后就较对照组改善明显，差异有统计学意义（P＜0.05）；7个月后随访疼痛复发人数治疗组较对照组少，差异有统计学意义（P＜0.05）。 结论 阳性激发点推拿联合依托芬那酯凝胶治疗方案对改善颈肩背肌筋膜炎引发的颈肩背部疼痛不适等症状优于传统推拿组，值得临床推广运用。

目的:探讨老老年患者颈动脉中层厚度(IMT)及其相关危险因素的关系,为老老年患者心脑血管疾病的预防及治疗提供临床参考。方法:根据年龄将139例老老年患者纳入分析,有血糖、血压、血脂代谢紊乱的123例作为观察组,无血糖、血压、血脂代谢紊乱的16例作为对照组,分别进行颈动脉超声检查、动态血压监测、糖化血红蛋白及血脂等生化指标检查,并结合临床资料进行分析。结果: 老老年患者均无一例外地存在着IMT增厚,在相同的年龄情况下,吸烟史、血脂紊乱、糖调节异常、血管炎症反应与IMT的增厚呈正相关,各组未显示出统计学差异,IMT的发生发展与年龄、性别、吸烟史、血糖、血压控制水平及血脂紊乱等因素在两组对照中均未显示出统计学差异,多因素Logistic回归分析,显示年龄、吸烟史及病程为危险因素(OR为0500～1196)。结论:老老年患者均不同程度地存在着IMT增厚,其中增龄是其最主要的危险因素,但是对合并有血糖、血压、血脂代谢紊乱的老老年患者也应该积极重视对各种危险因素的筛选和干预,特别在疾病发生发展的早期可能对延缓病变的进展和减少心脑血管事件有一定意义,可是其用药的安全性在该类患者就显得尤为重要。
