Objective: To analyze the effect of colorectal cancer screening in the general population in Guangzhou, and provide evidence for the for development of colorectal cancer screening policy and strategy. Methods: The data of colorectal cancer screening in Guangzhou during 2015- 2016 were collected. The participation, the positive rate of fecal occult blood test, the detection rate of colonoscopy and screening effect of colonoscopy were evaluated. Results: A total of 220 834 residents aged 50-74 years received the screening, and the positive rate of the screening was 16.77% (37 040 cases). Colonoscopy was performed for 7 821 cases (21.12%). Colorectal lesions were found in 4 126 cases (52.76%), of which 614 (7.85%) and 73 (0.93%) and 230 (2.94%) were identified as advanced adenoma, severe dysplasia lesions and colorectal cancers, respectively. The detection rates of all colorectal lesions were higher in men than in women (all P<0.01). The diagnostic rate of early lesion was 87.24%, and 99 early cancer cases were found, accounting for 46.26% of the total cases. The overall screening detection rate of colorectal cancer was 104.15/100 000, higher than the incidence rate (81.18/100 000) in colorectal cancer surveillance (P<0.001), but age group <70 years had higher detection rate, age group ≥70 years had higher incidence rate. Conclusions: The colorectal cancer screening strategy in Guangzhou is effective in the detection of the population at high risk, increase the detection rate of colorectal lesions, early diagnosis rate of precancerous lesions and diagnosis rate of early colorectal cancer. The benefit in those aged ≤69 years was more obvious than that in those aged 70-74 years. It is necessary to improve the compliancy of colorectal cancer screening in population at high risk.

Objective: To investigate the rates on prevalence, awareness, treatment and control of hypertension in population older than 15 years of age in Beijing, 2013-2014. Methods: A cross-sectional survey was conducted in Beijing between 2013-2014. Stratified multistage random sampling method was used to select representative sample of 13 057 Chinese individuals aged over 15 years, from the general population. Blood pressure was measured for three readings at sitting position after resting for at least five minutes with an average reading recorded. A standardized structured questionnaire was developed to collect history of hypertension and antihypertensive treatment. Results: A total of 4 663 community residents aged over 15 years were hypertensive among the 13 057 individuals, with the standardized prevalence rate as 32.7%, in Beijing area. The age-standardized prevalence rates of hypertension appeared 34.6% in men and 30.8% in women. The age-and sexstandardized prevalence of hypertension rates were 33.3% in urban and 24.6% in rural areas. The prevalence of hypertension increased with age and appeared higher in men than in women, in urban than in rural residents. Among the hypertensive patients, rates of awareness, treatment and control were 66.8%, 64.6% and 31.6%, respectively. Conclusion: High prevalence of hypertension with low rates on awareness and treatment and control, appeared in the general population of Beijing. Related strategies should be developed regarding prevention, control and management of hypertension, to reduce the burden of this disease.

Objective: To analyze the prevalence and co-prevalence of cardio metabolic (CM) risk factors in adults in China. Methods: The project data of 2015 Nutritional Status and Health Transition of Chinese Residents were used, and 5 456 adults aged 18-59 years with complete socio-demographic, anthropometric, and blood biochemical data were selected as the study subjects. The definition released by the International Diabetes Federation in 2005 were used to define each CM risk factors, including central obesity, elevated TG, reduced HDL-C, elevated blood pressure and elevated FPG. The co-prevalence of the risk factors was defined as adults having ≥2 risk factors. Multivariable logistic regression analysis was performed to evaluate the relationship between CM risk and socio-demographic factors. Results: About 80.8% of adults had at least 1 risk factor, and 54.0% had co-prevalence of risk factors. Gender, age, education level and living area were significantly associated with the prevalence of major metabolic risk factors. After adjusting for other factors, compared with men, women were more likely to have central obesity and reduced HDL-C, but not more likely to have elevated blood pressure, elevated FPG and elevated TG (P<0.01). Compared with adults aged 18-44 years, adults aged 45-59 years were more likely to have central obesity, elevated blood pressure, elevated FPG and elevated TG (P<0.01). The odds of having central obesity, elevated blood pressure and elevated fasting plasma glucose in the adults in eastern China were significantly higher than those in the central and western China. Conclusions: In 2015, less than 20% of the adults aged 18-59 years in China had no cardio metabolic risk factors, and more than half of them had two or more risk factors. Gender, age and living areas were the major influencing factors. It is necessary to take effective intervention measures targeting adults at high-risk for the early prevention of cardiovascular disease.

Airway edema, stenosis, obstruction and even asphyxia are easy to occur in patients with extensive burn, deep burn of head, face, and neck area, inhalation injuries, etc., which threaten life. Timely tracheotomy and intubation is an important treatment measure, but lack of knowledge and improper handling in some hospitals resulted in airway obstruction. The technique of percutaneous tracheotomy and intubation provides convenience for emergency treatment of critical burns and mass burn. The Burn and Trauma Branch of Chinese Geriatrics Society organized some experts in China to discuss the indications, timing, methods, extubation, and precautions of tracheotomy and intubation for burn patients.

Objective: To analyze the mortality and years of life lost (YLL) trends of cervical cancer in Tianjin, and provide references for the research and prevention programs of cervical cancer. Methods: Mortality rate, standard mortality rate, cumulative rate (0-74 years-old) and truncated rate (35-64 years-old) of cervical cancer from 1999 to 2015 were calculated. The annual percentage change of the mortality rate and YLL rate were analyzed by using Joinpoint regression analysis, and the trend in different age-groups were analyzed. Results: From 1999 to 2015, 1 741 cases died of cervical cancer in Tianjin, the average crude mortality rate was 2.15/100 000. The average age-standardized rate of (ASR) China and ASR world were 1.47/100 000 and 1.50/100 000 respectively. The average YLL was 3 347.97 person-years. Deaths occurred in those aged 0-34 years, 35-64 years and 65 years and over accounted for 3.10%, 57.84% and 39.06% of the total, respectively. The mortality rate of cervical cancer in urban area was higher than that in rural area, with a ratio of 1.37∶1 between urban area and rural area. The age-specific mortality rate of cervical cancer during 1999-2015 increased with age. Two peaks of mortality rate were observed in those aged 50 years and aged 75 years, during 2014-2015. From 1999 to 2011, the mortality rate of cervical cancer was stable (APC=-0.2%, P=0.80), but there was a rapid increase from 2011 to 2015 (APC=21.6%, P<0.01). But group aged 20-49 years, it showed an upward trend from 1999 to 2015 (APC=6.9%, P<0.01). For group aged 50-69 years, it showed a downward trend from 1999 to 2007 (APC=-9.2%, P<0.01), and an upward trend from 2007 to 2015 (APC=14.5%, P<0.01). For group aged 70 years and over, it showed a downward trend from 1999 to 2009 (APC=-10.2%, P<0.01), but the difference in the mortality were not significant from 2009 to 2015 (APC=7.8%, P=0.10). Since 2008, the YLL rate of cervical cancer in group aged 50-70 years had exceeded that in group aged >70 years and the gap gradually widened. Conclusions: There had been a rapid increase trend of cervical cancer mortality since 2011 in Tianjin. Women aged 50-70 years were the main group of life loss.

8.Status in clinical and molecular characteristics of differentiated thyroid carcinoma in children and adolescents.
Chinese Journal of Surgery 2023;61(9):744-748
The epidemiological, clinical, and molecular characteristics of differentiated thyroid carcinoma (DTC) in children and adolescents are different from those in adults. The incidence of DTC in children and adolescents is very low, with high rates of lymph node metastasis, extra-thyroidal extension and recurrence, but mortality is lower than that in adults. Younger children with DTC tend to show a higher rate of recurrence, more lymph node metastases, and more extra-thyroidal extension. Furthermore, studies on molecular characteristics suggest that the diversity of gene mutations causes the clinical manifestations of DTC in children and adolescents that are different from those in adults. The incidence of gene fusion is significantly higher than in adults, while the incidence of point mutations is lower than in adults, which may be closely related to clinicopathological characteristics such as high tumor aggressiveness and poor prognosis.

OBJECTIVE:To systematically evaluate the efficacy and safety of Kuanxiong aerosol in the treatment of coronary heart disease angina ,and to provide evidence-based reference for climical drug use . METHODS :Retrieved from Cochrane Library,PubMed,Embase,CKNI,Wanfang data ,VIP,and CBM ,randomized controlled trials (RCTs)about Kuanxiong aerosol (trial group )versus nitroglycerin (control group )in the treatment of coronary heart disease angina were collected during the inception to Mar. 20th,2020. After literature screening and data extraction ,quality assessment was performed using the bias risk assessment tool recommended by the Cochrane System Evaluator Manual 5.1.0. Meta-analysis was performed by using Rev Man 5.3 statistical software. Sensitivity analysis was conducted for the stability of the result ,and trial sequential analysis (TSA)was performed by using TSA 0.9 software. RESULTS :A total of 11 RCTs were included ,with a total of 1 847 cases. Meta-analysis showed that improvement rate of angina pectoris (within 3 min)[RR=1.11,95%CI(1.02,1.22),P=0.02] and total response rate of angina pectoris (within 5 min)[RR=1.04,95% CI(1.01,1.07),P=0.01] in trial group were significantly higher than control group;the incidence of ADR [RR=0.44,95%CI(0.35,0.57),P<0.000 01] in trial group was significantly lower than control group. There was no statistical significance in total response rate of ECG [RR=1.02,95%CI(0.97,1.09),P=0.42] or the level of NO after treatment [SMD =-0.08,95%CI(-0.61,0.45),P=0.76] between 2 groups. The results of sensitiv ity analysis and TSA showed that the efficacy evidence of Kuanxiong aerosol in the treatment of coronary heart disease pectoris was not accurate ,but the evidence of safety was accurate. CONCLUSIONS :Kuanxiong aerosol can improve the efficacy in patients with coronary heart disease angina ,and the safety is better ,but the conclusions of efficacy needs to be further confirmed by enlarging sample size.

Previous studies showed that crude antigens from Trichinella spiralis adult worms
(AW) can be recognized by mouse infection sera at 8 days post infection. The aim of this study
was to identify the early diagnostic antigenic bands in soluble proteins from T. spiralis AW by
Western blot using early infection sera. The affecting factors of adult recovery were firstly
observed in this study, and the results showed that the maximum number of adults was
collected from small intestine when the female BALB/c mice were orally infected with 4000
ML and sacrificed at 3 days post infection. The results of Western blot analysis showed that
seven protein bands (31, 35.1, 39, 40.6, 41.9, 47 and 50.6 kDa) could be recognized by early
infection sera as early as at 8-10 days post infection, and were strongly reacted with mouse
infection sera at 11-12 days post infection. Our results suggested that the seven protein
bands of T. spiralis AW soluble proteins might be the early expressed antigens during the
intestinal stage of Trichinella infection and therefore have potential value for the early
diagnosis of trichinellosis.
