ABSTRACT
Objective To investigate the prevalence of high-risk HPV subtypes in different pathological types of cervical cancer, and analyze the attribution of carcinogenic HPV subtypes in different pathological types. Methods A total of 1 541 patients with cervical cancer were treated between February 2009 and October 2016 in Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College. The median age at diagnosis was 49 years (ranged 20-82 years old). The numbers of patients with cervical cancer from North China, Northeast China, East China, Central China and other regions (including Northwest, Southwest and South China) were 961, 244, 175, 87 and 74 cases, respectively. Pathological types: 1 337 cases of squamous cell carcinoma (SCC), 87 usual adenocarcinoma (ADC), 23 adenosquamous carcinoma (ASC), 20 mucinous carcinoma (MC), 19 clear cell carcinoma (CCC), 12 endometrioid carcinoma (EC), 25 neuroendocrine carcinoma (NEC), 9 serous carcinoma (SC), 5 villous adenocarcinoma (VADC) and 4 minimal deviation adenocarcinoma (MDAC). The prevalence of high-risk HPV in different regions, age groups at diagnosis and pathological types in cervical cancer were analyzed. The attribution of 13 high-risk HPV subtypes in different pathological types of cervical cancer based on proportional attribution method, and the attribution of high-risk HPV subtypes prevented by 9-valent HPV vaccine in SCC and ADC were calculated. Results (1) The prevalence of high-risk HPV in 1 541 patients with cervical cancer was 86.6% (1 335/1 541). The multiple high-risk HPV infection rate in patients with SCC ≥60 years old (23.0%, 37/161) was significantly higher than those in patients aged 45-59 years old and≤44 years old [11.4% (85/747) vs 11.7% (50/429), P<0.01], and the high-risk HPV infection rates of patients with cervical cancer in North China, Northeast China, East China, Central China and other regions were respectively 86.8% (834/961), 87.7% (214/244), 83.4% (146/175), 83.9% (73/87) and 91.9% (68/74). SCC (86.8%, 1 337/1 541) and ADC (5.6%, 87/1 541) were the most common pathological types in cervical cancer. The high-risk HPV prevalence of SCC, ADC, ASC, MC, NEC and VADC were 90.1% (1 205/1 337), 74.7% (65/87), 87.0% (20/23), 65.0% (13/20), 72.0% (18/25) and 5/5 respectively. The high-risk HPV infection rates of SC, EC, CCC and MDAC were 4/9, 3/12, 2/19 and 0/4 respectively. (2) According to proportional attribution, HPV 16 (69.5%), HPV 18 (5.6%), HPV 58 (2.2%), HPV 31 (1.9%), HPV 52 (1.4%) and HPV 33 (1.3%) were the six common high-risk HPV subtypes in SCC. While, HPV 18 (44.1%), HPV 16 (20.5%), HPV 52 (2.3%), HPV 58 (1.2%) and HPV 51 (1.2%) were the main carcinogenic subtypes in ADC. The main carcinogenic high-risk HPV subtypes of ASC, NEC and MC were HPV 18 and HPV 16. The total attribution of HPV 16, 18, 31, 33, 45, 52 and 58 prevented by 9-valent HPV vaccine in SCC and ADC were 82.6% and 68.1% respectively; the attribution of HPV 45 in SCC and ADC were only 0.8% and 0. Conclusions SCC and ADC are the main pathological types in cervical cancer. SCC, ADC, ASC, MC, NEC and VADC are closely related to high-risk HPV infection. HPV 16 is the main carcinogenic genotypes of SCC. HPV 18 maybe play an important role in the pathogenesis of ADC.
ABSTRACT
Objective@#To know the incidence of heat stroke and explore it's prediction model in Pudong New Area of Shanghai. @*Methods@#An epidemiological investigation was conducted on heat stroke cases in Pudong New Area of Shanghai from 2013 to 2017. Daily temperature data during this period were collected to explore it’s influence. @*Results@#246 heat stroke cases were reported and investigated, 70.3% (173/246) of them were male. 170 cases are severe heat stroke, accounting for 69.1%. 28 patients died, accounting for 11.4% of all cases of heat stroke, and 16.5% (28/170) of severe heat stroke cases. Thermoplegia (56.5%, 96/170) was the most popular type among severe heat stroke cases. Heat prostration, heat cramps and mixed type account for 17.1% (29/170) , 12.4% (21/170) and 14.0% (24/170) respectively. Scatter plot and linear regression demonstrated that there was a significant linear relation between number of high temperature days and number of heat stroke cases (P<0.01) . And the prediction model is: Predictive number of annual heat stroke cases=β×Number of annual high temperature days+Intercept. Leave-one-out cross validation result shows that the predictive number of annual heat stroke cases from 2013 to 2017 were 85.7%, 90.9%, 83.3%, 91.9 and 84.3% respectively. @*Conclusion@#There was a significant linear relation between number of high temperature days and number of heat stroke cases in Pudong New Area. The related work arrangement for heat stroke prevention could be well planed according to the prediction model.

OBJECTIVE:To investigate the application of fuzzy comprehensive evaluation in formulation screening. METH-ODS:Taking Compound paracetamol and chlorphenamine maleate granules as model drug,based on single factor experiment,L9(34) orthogonal test was used to screen the formulation with the amount of aspartame,hawthorn powder essence,milk powder essence and saccharose as factors,using dissolution rate of caffeine as index. The granules prepared by 9 kinds of formulation in orthogonal test were evaluated with fuzzy comprehensive evaluation in terms of taste,aroma,color and dissolubility. The optimized formula-tion was validated and compared with original formulation. RESULTS:The formulation 5 was the optimal choice in both orthogo-nal test and fuzzy comprehensive evaluation,and obtained same results. Compared with sensory comprehensive score (63.12) and dissolution rate of caffeine (91.3%) in original formulation,two indicators of optimized formulation in 3 tests were 84.00 and 99.07% in average (RSD<2.0%,n=3). CONCLUSIONS:Fuzzy comprehensive evaluation can be used for the formulation screening of sensory evaluation index. It is scientific and accurate.
ABSTRACT
Objective To explore the relationship between high-sensitivity C-reactive protein (hsCRP)and obesity/metabolic syndrome(MetS)related factors in children. Methods 403 children aged 10-14 and born in Beijing were involved in this study. Height,weight,waist circumference,fat mass percentage(Fat%),blood pressure(BP),hsCRP,triglyceride(TG),total cholesterol(TC), fasting plasma glucose(FPG),high and low density lipoprotein cholesterol(HDL-C,LDL-C)were observed among these children. hsCRP was transformed with base 10 logarithm(lgCRP). MetS was defined according to the International Diabetes Federation 2007 definition. Associations between MetS related components and hsCRP were tested using partial correlation analysis,analysis of covariance and linear regression models. Results 1) lgCRP was positively correlated with BMI,waist circumference,Fat%,BP,FPG,LDL-C and TC while negatively correlated with HDL-C. With BMI under control,the relationships disappeared,but LDL-C(r=0.102). 2)The distributions of lgCRP showed obvious differences in all the metabolic indices,in most groups,respectively. With BMI under control,close relationships between lgCRP and high blood pressure/high TG disappeared and the relationship with MetS weakened. 3) Through linear regression models, factors as waist circumference,BMI,Fat% were the strongest factors related to hsCRP,followed by systolic BP, HDL-C,diastolic BP,TG and LDL-C. With BMI under control,the relationships disappeared,but LDL-C (β=0.045). Conclusion hsCRP was correlated with child obesity,lipid metabolism and MetS. Waist circumference was the strongest factors related with hsCRP. Obesity was the strongest and the independent influencing factor of hsCRP.

ABSTRACT
<p><b>OBJECTIVE</b>To describe the trend of multiple pregnancies and to compare the results with single pregnancy in Beijing from 1996 to 2010. Prevalence rates of pregnancy complications were compared between multiple and single pregnancies.</p><p><b>METHODS</b>In 1996, 1997, 1998, 1999, 2000, 2005, 2010, live births in two hospitals in Beijing were included to describe the trend of multiple and single pregnancy. Case-retrospective analyses were used. Information was collected, including maternal age, fetus number, delivery mode, with/without pregnancy induced diseases as hypertension, diabetes or anemia, gender of the baby, birth-weight and gestation etc. Linear regression analyses were applied to assess the trend of birth-weight and the rates of prevalence.</p><p><b>RESULTS</b>63 661 babies and 62 895 puerperal were involved in this study. From 1996 to 2010, prevalence of multiple pregnancies increased by 0.02%, prevalence of cesarean delivery among multiple pregnancy women increased by 2.25% and the proportion of women older than 30 years increased by 3.52% and 2.89% among multiple or single pregnancy women, annually. However, the birth-weight did not show obvious change in both multiple and single birth babies. No obvious change was observed in the prevalence of low birth weight. Prevalence rates of premature birth increased by 1.62% and 0.16% among multiple and single pregnancy women, annually. From 1996 to 2010, the mean values of birth-weight among single birth babies were larger than 3 250 grams and under 2 500 gram among multiple birth babies. Rates of prevalence on pregnancy induced hypertension and anemia were higher in multiple pregnancy women than in single pregnancy women. Differences of rates on prevalence rates of pregnancy diabetes between multiple and single pregnancy women were not statistically significant.</p><p><b>CONCLUSION</b>Prevalence of multiple pregnancies increased from 1995 to 2010 in Beijing. Mothers of multiples were more likely to get pregnancy complication than the single pregnancy women.</p>

<p><b>OBJECTIVE</b>To analyze the trends on the prevalence rates of obesity and cardiometabolic among children and adolescents in Beijing, during 2004-2013.</p><p><b>METHODS</b>Data was collected from three cross-sectional studies among children and adolescents, aged 7-17 years old in Beijing. Two studies in 2004 and 2013 were conducted in general population, and one was among obese children in 2007. Data on anthropometric measurements including weight, height, and age was collected from all the subjects. The obese children from all three studies underwent a clinic examination that containing blood pressure, fasting plasma glucose, lipid profile (TC, TG, LDL-C, HDL-C), and acanthosis nigricans. Liver transaminases detection (ALT and AST) and liver ultrasound examination were performed in obese children from surveys in 2007 and 2013.</p><p><b>RESULTS</b>The prevalence of severe obesity increased from 1.86% in 2004 to 4.17% in 2013, with an annual increase rate as 0.26%. The proportion of severe obesity in obesity increased from 18.92% in 2004 to 25.15% in 2013. After adjusting for age and gender, the prevalence of IFG, hypertriglyceridemia and low HDL-C in both obese children and adolescents increased during 2004-2013 (all P < 0.05). The prevalence rates of hypertension, dyslipidemia, hypertriglyceridemia, and acanthosis nigricans in severe obese children were higher than those in moderate obesity. The proportion of children with 2 or more cardiometabolic risk factors in severe obese children was higher than in moderate obese children.</p><p><b>CONCLUSION</b>The prevalence rates of obesity and cardiometabolic risk factors among children and adolescents in Beijing showed an increase during 2004-2013.</p>
