  • Incidence Trend of Female Breast Cancer in Urban Shenyang from 2000 to 2009

    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.

  • Smoking and Risk of Endometriosis: A Meta-Analysis of Case Control Studies

    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.

  • Investigation on the Incidence of Urolithiasis in Infants Fed by Milk Powder Tainted with Melamine in the Middle Area of Anhui Province

    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.

  • Epidemiological Characteristics and Trends of Malignant Tumors in Chengdu

    Objective To investigate the morbidity and mortality of malignant tumors in Chengdu, and get to know their epidemiological characteristics and trends, so as to provide evidence for the policy-making of tumor prevention and control. Methods The ICD-10 coding method was used to analyze the morbidity and mortality of malignant tumors in different ages, genders, areas and types, based on the surveillance data in Chengdu collected from 1990 to 2010. Results The reporting morbidity rose from 32.29/100 000 in 1990 to 171.63/100 000 in 2010, while the reporting mortality rose from 87.03/100 000 in 1990 to 177.51/100 000 in 2010. Liver cancer was seen with the highest morbidity and mortality rate in Chengdu in 2010. The mortality of cancer was higher in male than in female (233.49/100 000 vs. 121.12/100 000). No significant differences were observed between city and rural areas (177.84/100 000 vs. 176.95/100 000). Conclusion The morbidity and mortality rates of tumor are rising year by year, and tumor has become the main disease threatening people’s health. It is suggested that earlier prevention and control measures should be implemented as soon as possible.

  • Effect of Vitamin A Supplementation on Morbidity and Mortality in Children with Infectious Diseases

    Objective To evaluate the effect of vitamin A (Vit A) supplementation on the morbidity and mortality in children with infectious diseases. Methods We searched Cochrane Library (Issue 1, 2004), MEDLINE (1966-2004.3) and The PedsCCM Evidence-Based Journal Club (1992-2002). Relevant systematic reviews and randomized controlled trials (RCTs) of Vit A supplementation on morbidity and mortality in children with infectious diseases were obtained. Results We collected 107 studies and identified 13 systematic reviews or RCTs. The evidence showed that the effect of Vit A supplementation on morbidity and mortality was affected by the nutritional status of the children. Vit A supplementation given to Vit A deficient children could reduce the morbidity of diarrhea and mortality of measles. However, Vit A supplementation would increase the morbidity of diarrhoea and respiratory infections in children with sufficient nutrition. Conclusions The nutritional status of children correlates with morbidity and mortality of some infectious diseases, and the nutritional status and serum Vit A level should be evaluated before Vit A supplementation applied.
