OBJECTIVETo investigate the prevalence and relevant factors on the echocardiographic left ventricular hypertrophy (LVH).

METHODA cross-sectional study was conducted among the hypertensive patients in an urban community.

RESULTSThe prevalence of LVH was 29.2% in 1 686 hypertensive patients, with 25.4% in males and 34.5% in females, respectively. The prevalence was significantly higher in females than in males (chi(2) = 16.17, P < 0.01). The rate was increasing with age and significantly higher prevalence was observed in 45-, 55-, 65- age groups of females (P < 0.05). Moreover, elevated systolic blood pressure and higher BMI were related to the LVH in hypertensive patients, while higher education level seemed a protective factor.

CONCLUSIONThese results implied that a comprehensive intervention should be taken in the prevention of LVH.

Objective To analyze projects completed at the end of 2017 and funded by National Natural Science Foundation of China (NSFC) in the field of skin and its appendages,in order to provide references for preparing concluding reports and making discipline development strategies in the future.Methods The concluding reports of projects completed at the end of 2017 and funded by National Natural Science Foundation of China in the field of skin and its appendages were collected from the Internet-based Science Information System.The achievements were analyzed,including journal articles,patents,talent training and monographs.Results A total of 91 projects were completed at the end of 2017 in the field of skin and its appendages,and the total cost of funds was 43.51 million RMB Yuan.A total of 452 journal articles were published,including 324 articles in the Science Citation Index (SCI)-indexed journals and 42 in the A Guide to the Core Journal of China-indexed journals.Additionally,0.74 SCI journal article and 0.10 Chinese core journal article could be produced per 100 000 RMB Yuan.The average impact factor of journals publishing these SCI articles was 3.972,and in average,100 000 RMB Yuan yielded 1 article in the journal with an impact factor of 2.92.Of the 324 published articles,46 and 102 were published in journals ranked within the first (Q1) and second (Q2) quartile,respectively,by Chinese Academy of Sciences.In all the SCI articles,14 were published in journals with impact factor of ＞ 10.There were 4 institutions with more than 5 completed projects,and a total of 129 (39.84％) SCI articles were published.Published SCI articles in the field of immune skin diseases accounted for the highest proportion (148/324,45.68％).A total of 152 talents were trained.Conclusions The support of NSFC in basic researches in the field of skin and its appendages has led to substantial achievements.More attention should be paid to the writing of concluding reports.Innovation consciousness should be raised,and project leaders should make more original and leading achievements in the future.

Objective:To assess the prevalences of hypertension, rates of medication recommendations and failure rates of blood pressure(BP)control in Chinese elderly patients(≥65 years old).Methods:We used data from the 2011 China Health and Nutrition Survey(CHNS). A total of 2, 391 Chinese adults aged≥65 years with complete information comprising BP measurements repeated three times and antihypertensive medication use were included for analysis.Results:The mean age of subjects was 72.6±6.2 years, and females accounted for 53.1%.The numbers of patients with hypertension were 1784(74.6%)and 1221(51.1%)according to the definitions from 2017 ACC/AHA guideline and the 2010 Chinese guideline, respectively.There was a significant difference in the prevalence of hypertension in the subgroup with a cardiovascular disease(CVD)history according to the definitions from the two guidelines( χ2=23.70, P<0.01). The BP thresholds for drug therapy recommendations were the same as those set in the diagnostic criteria of hypertension based on the two guidelines.Therefore, the rates for medication recommendations were 74.6% and 51.1%, respectively.The numbers of patients with BP above the target levels were 622(88.2%)and 346(49.1%), respectively, according to the definitions from the two guidelines.There was no significant difference in failure rate of BP control due to age( χ2=5.36, P>0.05), gender( χ2=0.12, P>0.05)or a CVD history( χ2=0.07, P>0.05)according to analyses using the definitions from the two guidelines. Conclusions:Compared with the 2010 Chinese hypertension guideline, the prevalence of hypertension and rate of medication recommendations are higher in the Chinese elderly population when the 2017 ACC/AHA hypertension guideline is used.Hypertension management and antihypertensive drug treatment should be reinforced to improve the control rate of hypertension.

We analyzed the project results of preventive medicine from the National Natural Science Foundation of China (NSFC) finished in 2017 based on the project-ending reports and data on science fund sharing service network. A total of 406 projects in this field were completed in 2017. A total of 3 122 published articles supported by these projects, including 1 789 articles in science citation index (SCI) journals and 525 articles in Chinese core journals. In addition, there were 224 patent application/software copyright and 589 trained postgraduates. The top three sub-disciplines of project were non-communicable disease epidemiology, human nutrition and hygienic toxicology, accounting for 45.32% of the total number of completed projects. There were 12 institutions which had more than 10 finished projects, accounting for 41.87%. During the recent 5 years, the number of SCI articles and patents/software copyrights per project showed a general uptrend. It should be noted that the number of articles in Chinese core journals and postgraduates decreased in recent two years. Our analyses demonstrated that the project results should be guided by the new era policy of science fund to promote sustainable development of scientific research.

Objective To explore the relationship between socioeconomic status and the risk factors of cardiovascular diseases in retirees from a community in Shanghai. Methods Observational study involved 9 943 retirees aged 50 and over in Shanghai. Both single factor and multi-factor analyses methods were used to describe the correlation between factors as:educational level,marital status,annual household income and risk of hypertension,coronary heart disease,stroke etc. A new defined compound index was used to assess the relevance of socioeconomic status on the risk of cardiovascular diseases,based on logistic regression model. Results After adjusted for age,the risk of cardiovascular diseases in these retirees was influenced by socioeconomic status. In general, opponent correlations in education levels and prevalence of hypertension were found between female and male. Compared with those having received college or higher education,the risk of hypertension increased in females when the education level declined,with OR as 1.08(95%CI:0.89-1.30). For those having had senior high school junior high school or elementary education,the risks of hypertension were 1.26(95%CI:1.05-1.51),1.34(95%CI:1.08-1.65),0.72(95%CI:0.59-0.87),0.78 (95%CI:0.64-0.94),and 0.70(95%CI:0.52-0.92)for males,respectively. The risk of cardiovascular diseases increased with annual household income. Compared with high level of socioeconomic status, lower socioeconomic status might decline the risk of cardiovascular diseases in males by approximately 30%,with OR for medium being 0.72(95%CI:0.61-0.84)and for lower ones it was 0.70(95%CI:0.57-0.87). However,similar correlations were not found in females. No significant relationship was found between marital status and the prevalence of cardiovascular diseases in this study. Conclusion The risks of cardiovascular diseases varied with different socioeconomic status, indicating that tailored interventions should be conducted in different socioeconomic groups.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
