Objective To explore the incidence, age distribution and change tendency of female breast cancer in urban Shenyang from 2000 to 2009. Methods The incidence data of female breast cancer recorded in Shenyang Center for Disease Control and Prevention from 2000 to 2009 were collected, and the incidence and standardized incidence of breast cancer were analyzed by using SPSS 16.0 software. The incidence trend was analyzed by means of χ2 trend test and linear regression. Results The annual average crude incidence rate of female breast cancer in urban Shenyang from 2000 to 2009 was 46.03/100 000, while the annual average standardized incidence rate was 35.63/100 000, increased by 160.41% and 109.39% respectively during past 10 years, and the annual average increase was 11.22% and 8.56%, respectively. Both crude incidence rate and standardized incidence rate were in increasing trends with statistical significance (Plt;0.001). The crude incidence rate of the female at age of 50-64 showed a perpendicular rise trend, increased by 271.97%, and the annual average increase was 15.72%. The χ2 trend test and linear regression showed a significant difference (χ2=276.743, P=0.000; y= –22 355.560+11.205x, P=0.000). Conclusion The incidence of female breast cancer in urban Shenyang tends to rise with a younger-aged trend, and the female at age of 50-64 are commonly affected.
Objective To systematically assess the correlation between smoking and the risk of endometriosis, so as to offer scientific basis to health education and preventing decision. Methods A literature search was performed in The Cochrane Library, Pubmed, Embase, CBM, CNKI and Wanfang database to collect the case control studies on the correlation between smoking and endometriosis. Two reviewers independently screened the literatures according to the inclusion and exclusion criteria, extracted the data, assessed the quality, and then conducted Meta-analyses on the 13 included RCTs by using RevMan 5.0 software, with calculation of the OR value and 95%CI. Results A total of 13 case control studies involving 14260 cases were included, of which 1900 ones were endometriosis. The quality assessment indicated that 2 studies were in quality of Level A, 4 were Level B, 7 were Level C, totally meant low quality. Meta-analyses showed that compared with non-smokers, there was no increasing possibility of endometriosis in smokers (OR= 0.91, 95%CI 0.82 to 1.02). The geographical subgroup analyses showed there was no significant difference in the incidence of endometriosis between the non-smokers and smokers in North America (OR=0.96, 95%CI 0.84 to 1.08), but a significant difference was found between non-smokers and smokers in Europe (OR=0.72, 95%CI 0.54 to 0.97). Conclusion There is no causative relationship between smoking and incidence of endometriosis. However, more high-quality trials are expected for further study because of the heterogeneity and poor quality of the current included studies.
Objective To investigate the incidence of urolithiasis in infants aged 0-3 years old fed by milk powder tainted with melamine in the middle area of the Anhui province, as well as its relationship to gender, age, milk powder consumption and drinking water. Methods Questionnaires were distributed to 1079 infants who were screened for urolithiasis by ultrasound examination from September 25, 2008 to October 17, 2008. Data was collected by Epidata and analyzed by SPSS 13.0 software. Results A total of 646 (59.87%) male infants and 433 (40.13%) female infants underwent ultrasound examination in Anhui Provincial Hospital. Of these, 86 infants were diagnosed with urolithiasis with an incidence of 7.97%, including 62 males (72.09%) and 24 females (27.91%). The mean age of those infants with urolithiasis was 1.85±0.77, and all of calculus was located in kidney. The relationship between the incidence of urolithiasis and gender, age, drinking water, feeding bottle sanitation, birth status, as well as the amount of milk powder intake was assessed by using the Pearson Chi-square test. Results showed that significant differences were noted in the incidence of urolithiasis among infants of different genders or with different drinking water sources (Plt;0.05). The result of multiple logistic regression analyses indicated that gender was related to the incidence of urolithiasis (Plt;0.05). The incidence of urolithiasis in female infants was only 58.7% of that in male infants (OR 0.587, 95%CI 0.359 to 0.959). Conclusion The incidence of urolithiasis in infants aged 0-3 years of old in the middle area of Anhui province is relatively high and has anatomical specificity. Further data during the follow-up of these cases should be collected.
摘要:目的:分析本院住院城镇及农村患者的乙型肝炎病毒感染及免疫情况,推测不同区域发病及免疫状况,为免疫预防及临床提供参考。方法:收集我科2000年度,2004年度,2008年度住院患者的乙肝五项检测报告,按患者长期居住地分为农村组及城镇组,对比分析两组患者乙型肝炎病毒感染、具有免疫力及无免疫力年度变化情况及不同组别的差异。结果:同农村组相比,城镇组乙型肝炎病毒感染率、无免疫率低于农村组,免疫率高于农村组。年度对比乙型肝炎病毒感染率及免疫率呈上升趋势,无免疫率呈下降趋势。结论:近年来乙型病毒性肝炎发病有上升趋势,农村地区免疫普及率相对较低,仍为发病及预防免疫的重点区域,应给予足够重视。Abstract: Objective: To observe the disposition of infection and immunifaction on type B hepatitis in patients from hospital, suppose the disposition of infection and immunifaction in differently region, and provide information for immunifaction and clinical treatment. Methods: Reports of type B hepatitis from patients in hospital were collected, and were divided into town group and country group according to the habitation of patients. The difference of infection, immunifaction and no immunifaction were compared between two groups. Results: In comparison with the country group, the percentage of infection and no immunifaction was lower in town, and immunifaction was higher, attack rate of type B hepatitis had a tendency to increasing and no immunifaction was decreased by contrasting with annum. Conclusion: Recent years, attack rate of type B hepatitis has a tendency to increasing, and the popular rate of immunifaction is lower in country, so country is still the focal point of immunifaction and infection, and sufficient attention must be paid.
目的：分析我院近10年来异位妊娠发生率、发病年龄、诊断和治疗。方法：以5年为一个时间段回顾分析我院1997年1月至2006年12月异位妊娠发生率、发病年龄、诊断和治疗。结果：我院1997年1月至2006年12月共收治异位妊娠740例。异位妊娠数与同期宫内妊娠数之比，由1997年1月至2001年12月的1∶23.99上升为2002年1月至2006年12月的1∶11.60（P＜0.01）。≤25岁异位妊娠的发病率由1997年至2001年的14.7%上升到2002年至2006年的289%，其中≤20岁妇女及合并不孕者有增多趋势。异位妊娠的早期诊断率增高，发生异位妊娠破裂者由1997年至2001年的120例（45.3%）下降至2002年至2006年的85例（17.9%）（P＜0.01）。经腹行输卵管切除仍为主要治疗手段，但腹腔镜手术及保守性手术逐渐增多，非手术治疗明显增多。结论：异位妊娠发生率呈上升趋势，发病年龄年轻化，近年早期诊断率增高，减少误诊及异位妊娠破裂发生，经腹手术仍为主要治疗手段，但腹腔镜和保守治疗上升。
Objective To summarize the recent pathogenetic researches on the acute pancreatitis. Methods Relevant references about the pathogenesis of acute pancreatitis, which were published recently domestic and abroad were collected and reviewed. Results Recent experimental data indicated that the synthesis and release of pro-inflammatory cytokines and chemotactic factors were responsible for local injury and systemic dissemination of the inflammatory mediators. Experimental studies also provided evidences implying that the immune system might play a role in the development of pancreatitis, such as the activation of lymphocyte and neutrophil. Additionally, the pancreas may completely recover or become fibrotic after an attack of acute pancreatitis and the presence of pancreatic stellate cell was known as a crucial factor in the fibrogenesis. Conclusion The pathogenesis of acute pancreatitis is very complicated, the factors that determine the ultimate severity of the attack are still unknown.
