Objective: To investigate the prevalence of major chronic diseases among residents in Xiamen City, Fujian Province, so as to provide insights into enhancing the prevention and control of chronic diseases. Methods: The residents aged 18 years and older and lived for 6 months and more were selected from 6 districts in Xiamen City from 2021 to 2022 using the stratified random sampling method. Demographic information, disease history, blood pressure, fasting blood glucose and blood cholesterol were collected through questionnaire surveys, physical examination and laboratory tests. The prevalence rates of hypertension, diabetes and hypercholesterolemia were calculated and standardized using the 2020 National Population Census data, and were analyzed by age and gender. Results: Totally 22 289 residents were investigated, including 10 444 males (46.86%) and 11 845 females (53.14%). The prevalence rates of hypertension, diabetes and hypercholesterolemia were 15.35%, 4.30% and 10.45%, and the standardized prevalence rates were 16.25%, 4.81% and 10.21%, respectively. The standardized prevalence rates of hypertension, diabetes and hypercholesterolemia in males were 19.20%, 5.71% and 9.97%, respectively, and were higher than those in females, which were 13.62%, 4.03% and 10.29%, respectively (all P<0.05). The crude prevalence rates of hypertension and diabetes in males aged 18 to 59 years were higher than those in females, the crude prevalence rate of hypercholesterolemia in males aged 18 to 49 years was higher than that in females, and the crude prevalence rate of hypercholesterolemia aged 50 years and over in males was lower than that in females (all P<0.05). Conclusion From 2017 to 2022, the prevalence rates of hypertension, diabetes, and hypercholesterolemia in males were higher than those in females in Xiamen City, while the prevalence rate of hypercholesterolemia in females was higher than that in males after the age of 50 years.

Sequences analysis revealed Grass carp reovirus (GCRV) s10 was 909 nucleotides coding a 34 kDa protein denoted as VP7, which was determined to be a viral outer capsid protein (OCP). To obtain expressed OCP in vitro, a full length VP7 gene was produced by RT-PCR amplification, and the amplified fragment was cloned into T7 promoted prokaryotic expression vector pRSET. The recombinant plasmid,which was named as pR/GCRV-VP7,was then transformed into E.coli BL21 host cells. The data indicated that the expressed recombinant was in frame with the N-terminal fusion peptide. The over-expressed fusion protein was produced by inducing with IPTG, and its molecular weight was about 37kDa, which was consistent with its predicted size. In addition, the fusion protein was produced in the form of the inclusion body with their yield remaining steady at more than 60% of total bacterial protein. Moreover,the expressed protein was able to bind immunologically to anti-his-tag monoclonal antibody (mouse) and anti-GCRV serum (rabbit). This work provides a research basis for further structure and function studies of GCRV during entry into cells.

Objective: To examine the correlation between anxiety and perceived stress among medical personnel in a tertiary specialized cancer hospital, so as to provide the evidence for improving psychological health among medical personnel. Methods: In-service doctors, nurses and technicians were sampled from a tertiary specialized cancer hospital, and their demographics, perceived stress and sources of stress were collected using self-designed questionnaires. Anxiety was evaluated using the Self-rating Anxiety Scale (SAS), and the associations of anxiety with perceived stress and source of stress were examined using a multivariable logistic regression model. Results: A total 800 questionnaires were allocated and 655 valid questionnaires were recovered, with an effective recovery rate of 81.88%. The respondents included 160 men (24.43%) and 495 women (75.57%), and 297 respondents (45.34%) were at ages of 30 to 39 years. There were 14 respondents with no or low level of stress (2.14%), 245 with general level of stress (37.40%), 289 with high level of stress (44.12%), and 107 with extremely high level of stress (16.34%). The prevalence of anxiety was 36.64% among respondents. Multivariable logistic regression analysis identified perceived stress at work (OR=2.205, 95%CI: 1.657-2.675), doctor-patient relationship (OR=2.259, 95%CI: 1.561-3.282) and interpersonal relationship (OR=2.272, 95%CI: 1.387-3.693) as a factor affecting anxiety among medical personnel. Conclusion The anxiety correlates with stress at work, doctor-patient relationship and interpersonal relationship among medical personnel in a tertiary specialized cancer hospital.

OBJECTIVEThe interrelation of yield and agronomic traits of Gentiana rigescens was studied for the germplasm and breeding variety of this species.

METHODTwelve agronomic traits, root diameter, root length, root number, root biomass, stem diameter, plant height, the first branch number, leaf length, leaf width, leaf length/leaf width ratio, calyx length, and calyx number of G. rigescens from 26 wild populations in Yunnan were determined for correlation analysis, multiple stepwise regression analysis and path analysis.

RESULTCorrelation analysis showed that there were significantly positive correlation between the traits of aboveground part and the length, diameter, number, and biomass of the root. Multiple stepwise regression analysis showed that length, width, and number of root, plant height, the first branch number, and the calyx number were the main factors that affected the root biomass. Path analysis showed that the diameter, length, and number of the root, the stem height, and the first branch number had a direct positive effect on the root biomass.

CONCLUSIONThe traits, such as high and strong stem, high number of first branch number and shrubby shape could be selected for the breeding and high yielding of G. rigescens.

Objective To investigate the association of serum ubiquitin carboxy-terminal hydrolase L1 (UCH-L1) level with severity,progression and prognosis of traumatic brain injury (TBI).Methods Sixty TBI patients,admitted to our hospital from March 2012 to June 2013,were chosen in our study,and divided into moderate TBI group (Glasgow coma scale [GCS] scores:9-12,n=30) and severe TBI group (GCS scores:3-8,n=30);30 healthy controls were chosen.The serum UCH-L1 levels 12 and 24 h,and 2,3 and 5 d after TBI were detected using enzyme-linked immunosorbent assay (ELISA).Additionally,the correlations between serum UCH-L1 level and both imaging data and prognosis of TBI were analyzed.Results As compared with that in the control group,the mean serum UCH-L1 level in moderate TBI group and severe TBI group 12 and 24 h,and 2 and 3 d after TBI was significantly increased (P＜0.05);as compared with that in the moderate TBI group,the serum UCH-L1 level in severe TBI group 12 and 24 h,and 2 and 3 d after TBI was significantly increased (P＜0.05).The serum UCH-L1 level in the moderate TBI group reached the peak at 12 h after TBI,then gradually declined and presented no significant difference 5 d after TBI in comparison with controls.In severe TBI group,serum UCH-L1 level reached the first peak at 12 h,then gradually decreased,and rose again for the second peak 3 d after TBI.Serum UCH-L1 level was closely related with imageological changes and negatively correlated with prognosis of TBI (r=-0.412,P=0.030).Conclusion Serum UCH-L1 level appears to have potential clinical utility in providing valuable information about severity,progression and prognosis of TBI.

OBJECTIVES: The long-term trends of cognitive function and its associations with physical performance remain unclear, particularly in Asian populations. The study objectives were to determine cognitive trajectories in middle-aged and elderly Chinese individuals, as well as to examine differences in physical performance across cognitive trajectory groups. METHODS: Data were extracted from the China Health and Retirement Longitudinal Study. A total of 5,701 participants (47.7% male) with a mean age of 57.8 (standard deviation, 8.4) years at enrollment were included. A group-based trajectory model was used to identify cognitive trajectory groups for each sex. Grip strength, repeated chair stand, and standing balance tests were used to evaluate physical performance. An ordered logistic regression model was employed to analyze differences in physical performance across cognitive trajectory groups. RESULTS: Three cognitive trajectory groups were identified for each sex: low, middle, and high. For both sexes, higher cognitive trajectory groups exhibited smaller declines with age. In the fully adjusted model, relative to the low trajectory group, the odds ratios (ORs) of better physical performance in the middle cognitive group were 1.37 (95% confidence interval [CI], 1.17 to 1.59; p<0.001) during follow-up and 1.40 (95% CI, 1.20 to 1.64; p<0.001) at the endpoint. The ORs in the high trajectory group were 1.94 (95% CI, 1.61 to 2.32; p<0.001) during follow-up and 2.04 (95% CI, 1.69 to 2.45; p<0.001) at the endpoint. CONCLUSIONS Cognitive function was better preserved in male participants and individuals with higher baseline cognitive function. A higher cognitive trajectory was associated with better physical performance over time.
