Objective To investigate prevalence of chronic diseases, and the awareness & attitudes, and the health demand of residents aged ≥18 yrs in Shanghai communities. Methods 2 320 residents aged over 18 yrs were selected from 19 communities by multiple stage cluster sampling and questioned by face to face survey. Results The standardized self-reported prevalence rate of whole chronic diseases was 28.4%, hypertension was 21.8%, osteoporosis was 7.0%, diabetes mellitus was 6.3%, respectively, which were ranked the top three. The awareness of the hypertension and diabetes mellitus were accounted to 89.3% and 86.0%. The demands for the convenient and comfortable clinical environment in residents accounted to 80.6%. Conclusion The prevalence of chronic diseases in Shanghai was high. It's suggested to enhance the control and prevention of chronic diseases, particularly on hypertension, and to do more health education in suburbs.

The newly reported HIV infected cases was collected, and HIV blood samples were detected to identify recent HIV infection in Tianjin during 2008-2015. Factors associated with HIV-1 infection were analyzed by the univariate and multivariate unconditional logistic regression. The recent HIV-1 infection proportion of homosexuals increased from 37.70% in 2008 to 83.68% in 2015. Those cases who aged ≤30 years (OR=1.53, 95%CI: 1.30-1.79), in han ethnic group (OR=1.40, 95%CI: 1.02-1.91), students (OR=1.79, 95%CI: 1.28-2.51) were more likely to be recent infected. The cases who had a high school education (OR=1.28, 95%CI: 1.05-1.56) or collage education (OR=1.23, 95%CI: 1.00-1.50) were more likely to be recent infected than those who had a primary school education. Compared with patients identified by hospitals, the recent HIV infections were more likely to be found through voluntary counseling and testing (VCT), STD outpatients, men who have sex with men (MSM) investigation and unpaid blood donors. Homosexual transmission has become the major route of HIV-1 recent infection in Tianjin.

Objective To evaluate the auxiliary diagnostic value of viral load test for samples with indeterminate HIV antibody detection results.Methods Thirty-two samples with indeterminate HIV antibody detection results collected from MSM were used for two viral load tests in Tianjin in 2015.Follow up was conducted for this population to confirm their HIV infection status.Results Virus loads were detected in the 2 viral load tests.In the follow-up survey,the results of HIV antibody test of all the samples were positive.The results of viral load test were completely consistent with those of HIIV antibody confirmation test.Conclusion The viral load test was effective in the auxiliary diagnosis of HIV infection in window phase,which can be used for the samples with indeterminate HIV antibody detection results.

Objective To understand the characteristics on the diversity of HIV subtypes and related transmission in Tianjin.Methods A total of 77 newly diagnosed ART-na(i)ve HIV infectors in 2015 were screened by CD4 +T cell counts ≥200 cells/μl.Viral RNAs were extracted from plasma samples.Reverse transcription PCR and nested PCR were used to analyze the amplification of pol and env gene fragments,sequencing,and related bioinformatics information.Results 46.03％ (29/63),30.16％ (19/63),11.11％ (7/63),4.76％ (3/63) and 7.94％ (5/63) of the individuals were infected under HIV subtypes CRF01_AE,CRF07_BC,B,CRF55_01B and URFs,with sexual transmission as the major mode of infection.CRF01_AE and CRF07_BC strains were predominant in both MSM and HST populations.The patterns of subtype distribution did not show statistical differences other than subtype B and CRF55_01B strain among HSTs.The proportion of CRFs increased significantly to 88.89％.8 new second-generation recombinant forms were identified the first time,including 3 CRF55_01B,2 AE/BC,1 AE/B and 1AE/B/C among MSMs and 1 AE/BC among HSTs.5.3％ of the NNRTI L100I HIV infectors transmitted the drug-resistant-mutation strain.3 linkages related to HIV transmission were confirmed through phylogenetic analysis with Bootstrap ≥98％ of pol and ≥80％of env.Conclusion The increasing complexity of HIV had been noticed in Tianjin,including the prevalence and transmission of second-generation recombinant and drug-resistant strains through different routes of transmission and in different regions.

Objective:To analyze the influenza vaccination status of chronic disease management patients in Qingpu district of Shanghai and the vaccination characteristics of different characteristic populations, so as to provide scientific basis for improving the influenza vaccination rate of chronic disease patients in the community.Methods:By comparing the data of Shanghai chronic disease management information system, immunization planning information system and medical association platform, 89 453 subjects who met the inclusion and exclusion criteria in Qingpu district were selected as the research objects. The vaccination coverage rate of the study subjects was calculated according to gender, age group, urban and rural distribution, occupation, chronic disease type and quantity, and the vaccination coverage rate of different subgroups was compared to analyze the influencing factors of vaccination coverage rate.Results:Most of the 89 453 patients with chronic diseases were 60 years old and above (71.93%). Patients with hypertension, diabetes, chronic obstructive pulmoriary disease (COPD) and three chronic diseases accounted for 87.12%, 28.67%, 8.71% and 1.83%, respectively. Influenza vaccination coverage in the 2016/2017 flu season was low, at 0.32%. Influenza vaccination coverage rate of women (0.37%) was higher than that of men (0.27%), which was 1.41 times respectively(95% CI: 1.16, 1.72) that of men patients. The coverage rate of influenza vaccination for the 70-79 year-old group was the highest (0.74%), which was 1.74 times respectively(95% CI: 1.39, 2.19) that of 60-69 year-old patients. The vaccination coverage rate of government departments and institutions was the highest (1.14%), which was 12.58 times respectively(95% CI: 4.52, 34.99) that of retirees. The vaccination rate of COPD patients (3.68%) was 2.50 times (95% CI: 1.66, 3.77) higher than that of patients without COPD.Conclusions:Influenza vaccination rate for chronic disease management patients in Qingpu district of Shanghai is low. Gender, occupation, age and types of chronic diseases are the influencing factors. Patients with chronic disease management should be included in the priority vaccination targets for influenza vaccines, and vaccination intervention for occupational chronic diseases such as non-retired agriculture and forestry patients, especially male patients, should be strengthened to improve influenza vaccination coverage rate.

OBJECTIVE: To explore the genetic basis for a child with mental retardation. METHODS: Whole exome sequencing was carried out for the child. Candidate variant was screened based on his clinical features and verified by Sanger sequencing. RESULTS: The child was found to harbor a c.995_1002delAGACAAAA(p.Asp332AlafsTer84) frameshift variant in the SYNGAP1 gene. Bioinformatic analysis suggested it to be pathogenic. The same variant was not detected in either parent. CONCLUSION The c.995_1002delAGACAAAA(p.Asp332AlafsTer84) frameshift variant of the SYNGAP1 gene probably underlay the mental retardation in this child. Above finding has expanded the spectrum of SYNGAP1 gene variants and provided a basis for the diagnosis and treatment for this child.

ObjectiveTo evaluate the effect of standardized blood pressure measurement in consulting room （SBPM） model on blood pressure screening of non-hypertensive patients in community. MethodsFour communities were randomly selected from Fengxian District of Shanghai， and non-hypertensive patients in the communities were included for screening. Based on the communities， participants were further classified into the intervention group and control group. A one-year intervention study was conducted from January 1， 2021 to December 31， 2021. The intervention group received the intervention measures of standardized measurement， and the control group remained the routine measurement. The distribution of blood pressure values and last digit of the values between the intervention group and control group were tested using Chi-square test and normality test. Then changes in abnormal blood pressure rate before and after the intervention were determined by double difference method. Statistical analysis was performed using SPSS 20.0. ResultsA total of 15 368 participants were included in the intervention group， and 19 811 participants in the control group. After the intervention， range of the last digit of blood pressure values in the intervention group was 9.55%‒10.41%， of which that of systolic and diastolic blood pressure were equally distributed （P=0.932 and 0.871， respectively）. The range of the last digit in the control group was 1.31%‒42.58%， of which that of systolic and diastolic blood pressure showed unequal distribution （P<0.001）. Through one-year standardized measurement intervention， the abnormal rate of blood pressure in the intervention group was 26.29%， which was 7.61 times as high as that in the control group （OR=7.55， 95%CI： 6.75‒8.57， P<0.001）. ConclusionStandardized blood pressure measurement in consulting room is suitable for the screening of blood pressure measurement in community， which has higher data quality than that of routine measurement.

Objective: To investigate the prognostic value of arterial blood lactate for patients with cardiogenic shock receiving extracorporeal membrane oxygenation(ECMO). Methods: A retrospective analysis was conducted. Twenty-three patients diagnosed with cardiogenic shock receiving veno-arterial(V-A) ECMO admitted to department of Emergency Intensive Care Unit(EICU) of Beijing Luhe Hospital Affiliated to Capital Medical University from January 2017 to December 2018 were enrolled. Results: There were 10 cases in the survival group and 13 cases in the death group. Compared with survival group, APACHE-Ⅱ score was higher, CRRT applied higher percentage, PH and oxygenation index was worse in the death group(P<0.05). The lactate of the death group was significantly higher than that of the survival group at initial time at EICU, 1 h before ECMO and 0h before ECMO(P<0.05). During the ECMO operation, lactate levels in the death group at 8 h and 12 h were significantly higher than those in the survival group(P<0.05). There was no statistically significant difference in lactate clearance rate between the two groups before and after ECMO operation in each observation period(P>0.05). On the 2nd day of ECMO operation, CRRT usage time was shorter and daily liquid balance was more negative in the survival group(P<0.05). APACHE-Ⅱscore, initial lactate at EICU, lactate at ECMO 8 h and lactate at ECMO 12 h had predictive value for 30-day death of patients. The area under ROC curve(AUC) of initial lactate at EICU was 0.845, and 95% confidence interval(95%CI)=0.653-1.000. The AUC of ECMO 8 h lactate was 0.836, 95%CI: 0.634-1.000. The AUC of ECMO 12 h lactate was 0.873, 95%CI: 0.697-1.000. The AUC of APACHE-Ⅱscore was 0.891, 95%CI: 0.717-1.000. The sensitivity and specificity of prognosis prediction were 72.7% and 100% when lactate was more than 7.3 mmol/L at the time of admission into EICU as the optimal critical value. Conclusion Arterial blood lactate could be used as an important marker for evaluating the prognosis of cardiogenic shock patients on ECMO. The value of lactate clearance rate may be affected by combined CRRT.

Objective: To evaluate the clinical application of a novel HIV-1 DNA reagent. Methods: HIV-1-infected and non-infected human blood samples were selected, as well as weakly positive samples, indeterminate samples, specific samples. Compared the result of HIV-1 DNA reagent with HIV-1 infection status (refer to the National Guideline for Detection of HIV/AIDS (2015)), the accuracy of the HIV-1 DNA reagent was evaluated in clinical application; Meanwhile, the commercially available RNA quantification kit was selected as reference reagent for parallel detection, and then the consistency and differences were evaluated between HIV-1 DNA reagent and RNA quantification reagent. Results: A total of 95 whole blood samples were tested by the HIV-1 DNA reagent. Taking the HIV-1 infection status as the reference standard, the result showed that the positive agreement rate was 100% (95%CI: 93.94%-100%), the negative agreement rate was 100% (95%CI: 90.26%-100%), and the overall agreement rate was 100% (95%CI: 96.19%-100%). The Kappa value was 1 (95%CI: 1.00-1.00). The HIV-1 DNA reagent could detect weakly positive samples and indeterminate samples of early infection, and could effectively distinguish false-positive samples tested by the Ag-Ab reagent. The specific samples had no false-positive result . Conclusions The result of HIV-1 DNA reagent were consistent with the HIV-1 infection status. It can be considered as equivalent to the HIV-1 detection reagent commercially available in our country. It can effectively identify the indeterminate samples in the early infection. Compared with the RNA quantification reagent, it can effectively detect HIV-1 DNA of virus reservoirs.

ObjectivesTo investigate characteristics and influencing factors of short-term variation of systolic blood pressure of community hypertension patients in Shanghai. MethodsBased on the standardized blood pressure measurement data of hypertensive patients in Shanghai （2018‒2021） and the noninfectious chronic disease management system database， coefficient of variation of systolic blood pressure （CV_S） was described and the influencing factors were analyzed. ResultsAmong 112 680 community hypertension patients， males accounted for 46.87% with a median age of 69 years. CV_S was 0.038 6 ± 0.035 0. Generalized linear model analysis showed the following influencing factors of CV_S： gender， females were higher than males， B=0.032， P<0.001； age group， 60‒69 years， 70‒79 years old group， and ≥80 years groups were all higher than <50 years group， B=0.042， 0.056， and 0.074 respectively with P values of 0.020， 0.002， and <0.001 respectively； smoking， smoking cessation and smoking everyday was lower than never smoking， B=-0.032 and-0.028 respectively with P values of 0.023 and 0.007 respectively； systolic blood pressure， 140‒159 mmHg group， 160‒179 mmHg group， and ≥180 mmHg group were lower then <140 mmHg group， B=-0.039， -0.091， and -0.175 respectively with P values all <0.001； and measurement season， autumn was lower than spring， （B=-0.056， P<0.001）. The paired test showed that CV_S calculated from the three measurements was 1.04% higher than that calculated from the two measurements （P<0.001）. ConclusionThe coefficient of variation of systolic blood pressure of community hypertension patients in Shanghai has large variation， and was influenced by many factors.
