Objective: To create a prediction model for stroke risk among middle-aged and elderly populations, so as to provide a basis for early identification of high-risk population for stroke. Methods: From October to December 2023, residents aged ≥45 years in Chongchuan District, Nantong City, Jiangsu Province were selected using a multi-stage stratified random sampling method. The demographic information, life behavior, and chronic disease data were collected through a questionnaire survey. The standardized prevalence of stroke was calculated using data from the seventh National Population Census. The subjects were randomly divided into the training set and the internal validation set according to the ratio of 8∶2. The basic demographic information, life behavior, and chronic diseases of residents aged ≥45 years in Rugao City were collected from July to August 2023 as the external validation set. Predictive factors were selected using multivariable logistic regression model, and a nomogram for stroke among residents aged ≥45 years was established. The prediction effect was evaluated using the area under the curve (AUC) of the receiver operating characteristic (ROC), calibration curve, and Hosmer-Lemeshow goodness of fit test. Results: A total of 6 290 residents aged ≥45 years were included, including 2 975 males (47.30%) and 3 315 females (52.70%). The average age was (61.90±10.20) years. The prevalence of stroke was 3.80%, and the standardized prevalence was 3.36%. The multivariable logistic regression showed that age, smoking, hypertension, and hyperlipidemia were predictors of stroke risk among residents aged ≥45 years, and the prediction model was ln[p/(1-p)]=-4.619+0.046×age+0.383×smoking+0.887×hypertension+0.678×hyperlipidemia. The AUC values of the training set, internal validation set, and external validation set were 0.748, 0.755, and 0.738, respectively. The consistency indexes were 0.748, 0.755, and 0.738, respectively. The Hosmer-Lemeshow goodness of fit test showed a good fitting effect (P>0.05). Conclusion The prediction model based on age, smoking, hypertension, and hyperlipidemia has good discrimination and calibration, and can be used to predict the risk of stroke among middle-aged and elderly populations aged ≥45 years.

Objective:To examine the burden and trends of acute viral hepatitis in Guangdong Province from 1990 to 2019, and provide reference evidences for hepatitis prevention and control in the province.Methods:Data on acute viral hepatitis (hepatitis A, B, C, and E) in Guangdong from 1990 to 2019 were extracted from the Global Burden of Disease Study 2019 database. The incidence, prevalence, mortality, and disability-adjusted life years (DALY) data were analyzed by age and gender, and the estimated annual percentage change (EAPC) was calculated to describe the changing trends in disease burden.Results:From 1999 to 2019, the standardized incidence, prevalence, mortality, and DALY of acute viral hepatitis in Guangdong were higher than the national averages. In 2019, 51.43% (2 245 087/4 365 221) of acute viral hepatitis cases in Guangdong Province were mainly attributed to hepatitis B, and 77.18% (106/138) of deaths were due to acute hepatitis B. In different age groups, except for acute hepatitis B, which was more common in adults, the incidence rates of other types of viral hepatitis such as hepatitis A, B, and E showed an overall decreasing trend with age. The mortality rates of different types of acute viral hepatitis, except for the <5 age group, increased with age. The overall incidence and mortality rates of acute viral hepatitis were higher in men than in women.Conclusions:The overall burden of acute viral hepatitis in Guangdong declined in 2019, but remained higher than the national level. Further efforts are needed to strengthen hepatitis prevention and screening in different population in Guangdong Province, especially in children and the elderly.

【Objective】 To research the genetic polymorphism of HPA 1-6/10/15/21 in platelet donors in Zhongshan area, and establish a gene bank of platelet donors with HPA locus. 【Methods】 The HPA 1-6/10/15/21 system genotyping was performed by Real time fluorescent PCR combined with TaqMan probe technology on 192 platelet donors in Zhongshan area, and the genotype frequency and gene frequency were calculated. 【Results】 Only HPA-aa genotype was found within HPA-4/10, and no allele HPA-b had been detected. The majority of HPA-1, 2, 5, 6 and 21 genotypes were aa. HPA-3 and HPA-15 showed high heterozygosity, with genotype frequency of 0.307 3, 0.494 8 and 0.197 9 for HPA- 3aa, HPA-3ab and HPA-3bb, while 0.270 8, 0.505 2 and, 0.224 0 for HPA -15aa, HPA-15ab and HPA-15bb, respectively. 【Conclusion】 The distribution characteristics of HPA 1-6 /10/15/21 of platelet donors in Zhongshan shows regional differences compared with similar researches from other regions.

Balancing the risks and benefits of organophosphate pesticides(OPs)on human and environmental health relies partly on their accurate measurement.A highly sensitive fluorescence anti-quenching multi-residue bio-barcode immunoassay was developed to detect OPs(triazophos,parathion,and chlorpyrifos)in apples,turnips,cabbages,and rice.Gold nanoparticles were functionalized with monoclonal antibodies against the tested OPs.DNA oligonucleotides were complementarily hybridized with an RNA fluorescent label for signal amplification.The detection signals were generated by DNA-RNA hybridization and ribonuclease H dissociation of the fluorophore.The resulting fluorescence signal en-ables multiplexed quantification of triazophos,parathion,and chlorpyrifos residues over the concen-tration range of 0.01-25,0.01-50,and 0.1-50 ng/mL with limits of detection of 0.014,0.011,and 0.126 ng/mL,respectively.The mean recovery ranged between 80.3％and 110.8％with relative standard deviations of 7.3％-17.6％,which correlate well with results obtained by liquid chromatography-tandem mass spectrometry(LC-MS/MS).The proposed bio-barcode immunoassay is stable,reproducible and reliable,and is able to detect low residual levels of multi-residue OPs in agricultural products.

To observe the clinical efficacy of dopamine modulator methylphenidate (MPH) of extended-release formulations (MPH-ER) augmentation of ongoing fluvoxamine treatment in refractory obsessive-compulsive disorder (OCD) and its effects on patient's anxiety and sleep quality.
 Methods: A pilot randomized, placebo-controlled, and double-blind trial was conducted at an outpatient, single-center academic setting. Participants included 44 adults with serotonin reuptake inhibitor treatment-refractory OCD and they received a stable fluvoxamine pharmacotherapy with Yale-Brown Obsessive Compulsive Scale (Y-BOCS) scores higher than 20. The 44 patients were randomly assigned into a study group and a control group, with 22 patiencs in each group. Fluvoxamine and MPH-ER were given to the study group, while fluvoxamine and placebo were given to the control group, with 8 weeks of the treatment course. Y-BOCS, Hamilton Anxiety Scale (HAMA) were used to assess the efficacy, Pittsburgh Sleep Quality Index (PSQI) was used to evaluate the sleep quality, and Treatment Emergent Symptom Scale (TESS) was used to evaluate the side effects. Data were analyzed in the intention-to-treat sample.
 Results: The improvement in the Y-BOCS total score, Y-BOCS obsession subscale score and HAMA score were more prominent in the study group than those in the control group (P<0.001). There was no significant difference in PSQI score and TESS score between the two groups. MPH-ER was well tolerated.
 Conclusion: Fluvoxamine combined with MPH-ER is effective in the treatment of refractory obsessive-compulsive disorder. It can improve anxiety and has no adverse effect on sleep quality.

[ ABSTRACT] AIM: To investigate the differential expression of human leukocyte antigen-G ( HLA-G) isoforms and its receptors in human monocyte line THP-1 after human cytomegalovirus ( HCMV) infection for exploring the role of HLA-G in HCMV escaping the immune response of the organism .METHODS: THP-1 cells were infected with HCMV Towne strain.The expression of HLA-G isoforms at mRNA and protein levels was determined by RT-PCR and Western blot, respectively.The surface expression of HLA-G and its receptors ILT2/ILT4 and the cell viability were analyzed by flow cytometry.The levels of soluble HLA-G (sHLA-G) and IL-10 were measured by ELISA.RESULTS:After infection of the THP-1 cells with HCMV , no obvious apoptosis in the cells was observed , and the viability of the cells was high .A significant up-regulation of HLA-G1,-G3,-G4 and-G5 at mRNA expression level 1 d after infection was found , while the protein expression of HLA-G1 and HLA-G5 isoforms was mainly detected .The expression of HLA-G/ILT2/ILT4 was evi-dently up-regulated 1 d after infection .The level of sHLA-G was significantly increased 1 d after infection as compared with control group (P<0.01).The expression of IL-10 was obviously up-regulated 1 d post-infection as compared with control group.CONCLUSION:The differential expression of HLA-G isoforms and secretion of the receptors ILT 2/ILT4 and IL-10 in the THP-1 cells are induced after HCMV infection .This study provides experimental evidence for evaluating the immune mechanism of HCMV infection .

OBJECTIVETo describe the status of prevalence, awareness, treatment, and control of hypertension among half a million adults in 10 regions under the China Kadoorie Biobank (CKB) cohort.

METHODSThe baseline survey of CKB was performed in 10 areas across China during 2004-2008, included 512 891 adults aged from 30 to 79 years. Regional differences of prevalence, awareness, treatment and control of hypertension were compared after adjustment for age and/or sex.

RESULTSThe overall prevalence of hypertension from the CKB was 35.2% (180 612/512 891), with the highest as 44.4% in Zhejiang and the lowest as 22.0% in Haikou. Prevalence in the rural areas (35.1%) was higher than that in the urban areas (32.1%), with statistical significance (P<0.001). Among all the participants with hypertension, 59 703 (33.1%) were aware of hypertension, 65 172 (36.1%) were receiving anti-hypertension treatment and 22 329 (12.4%) were under controll. However, only a small part of those receiving treatment were under controll (30.5%, 19 884/65 172) in this study. The control of hypertension and of those receiving treatment were higher in Suzhou for males (17.4%, 39.1%), while were higher in Liuzhou for females (23.5%, 42.6%) than those in other regions.

CONCLUSIONSParticipants under the CKB presented relatively high prevalence of hypertension, but lower rates on awareness, treatment and control of hypertension. Distribution of awareness, treatment, and control of hypertension varied greatly among the ten areas, under the CKB.

Objective:To investigate the associations of major depressive disorder with coronary heart disease (CHD)and stroke in Chinese adults aged 30 -79 years.Methods:In 2004 -2008,China Ka-doorie Biobank was conducted in 1 0 geographically defined regions (5 urban and 5 rural)of China.A to-tal number of 51 2 891 participants aged 30 -79 years were recruited in the baseline survey.A laptop-based electronic questionnaire was administrated face-to-face by trained health workers,collecting the general demographic and socio-economic status,dietary and other lifestyle behaviours (e.g.smoking,al-cohol drinking,physical activity),medical history and family history of common chronic diseases.Major depressive episodes (MDE)in the past 1 2 months were assessed with the World Health Organization composite international diagnostic interview-short form (CIDI-SF).The physical measurements included the heights and weights,which were used to calculate the body mass indexes (BMI).Chi squared and t test were used to compare the differences in participants characteristics according to their major depressive disorder.Logistic models were employed to estimate the odds ratios (OR)and 95% CI of their major de-pressive disorder with prevalent coronary heart disease and stroke.Results:Among the 51 2 891 partici-pants,3 281 (0.6%)showed an MDE in the preceding 1 2 months,1 5 472 (3.0%)reported prevalent CHD,and 8 884 (1 .7%)reported prevalent stroke.Major depressive disorder was significantly associa-ted with an increased risk of CHD and risk of stroke.Age-and gender-adjusted ORs (95% CI)were 1 . 80 (1 .53 -2.1 2)for CHD and 2.53 (2.09 -3.05)for stroke.The associations were significant after further adjustment for potential confounders,such as other socio-demographic status,smoking,alcohol drinking,physical activity,and BMI,prevalent hypertension,diabetes as well as family history of cardio-vascular diseases (OR =1 .83,95% CI =1 .54 -2.1 8 for CHD;OR =2.1 9,95% CI =1 .79 -2.69 for stroke).Moreover,gender significantly interacted with MDE on prevalent stroke (P for multiplicative in-teraction =0.01 3).The men with an MDE in the past 1 2 months had the highest risk of stroke in the joint analyses of gender and depression disorder (OR =5.02,95% CI =3.70 -6.82).Conclusion:The findings from this large cross-sectional study suggest that the presence of MDE is a risk factor for both CHD and stroke in Chinese adults aged 30 -79 years,but further prospective studies are warranted to validate the results.

Objective To explore the relationship between the HLA-G 14 bp insertion/deletion polymorphism and the infection of Epstein-Barr virus(EBV) for children.Methods The study genotyped HLA-G 14 bp insertion/deletion polymorphism of 102 infectious mononucleosis children and 165 normal controls by PCR-PAGE,detected the plasma sHLA-G level of 51 infectious mononucleosis children and 146 normal controls by ELISA.Results A significant difference was observed for the frequencies of the HLA-G 14 bp genotype between the two groups( x2 =6.742,P=0.034 ),and a significant difference was also observed for the 14 bp allele frequencies between the two groups( x2 =6.672,P=0.01 ).The plasma sHLA-G levels in the infectious mononucleosis children were dramatically higher than that in normal controls,and a significant difference was observed between the two groups( Z=-9.472,P＜0.01 ).Among the infectious mononucleosis children,levels of sHLA-G was find a significant difference between the three genotypes of HLA-G 14 bp insertion/deletion polymorphism( H=6.09,P =0.048 ),and the level of s HLA-G with 14 bp+/+ genotype was markedly lower than that of the two other genotypes (Z=-2.376,P=0.01 8).Conclusion There was a relationship between the HLA-G 14 bp insertion/deletion polymorphism and the susceptibility to the infectious mononucleosis for children.Children who carried the 14 bp-/- genotype or deleted the 14 bp allele may have a significantly increased risk of the infection of EBV.The plasma sHLA-G might be considered as an index for auxiliary diagnosis infectious mononucleosis.
