bstract: Objective To elucidate the distribution characteristics of mosquito species and the population genetic diversity of important mosquito species in the Wuyi Mountain Nature Reserve, with the aim of providing a scientific basis for the prevention and control of mosquito-borne diseases in the region. Methods Within Wuyi Mountain Nature Reserve 2022- 2023, 16 sampling sites were selected, where larvae were collected using the pipette method and adult mosquitoes were collected using the mosquito trap lamp method. Mosquito species identification was accomplished by integrating morphological characteristics and molecular identification techniques based on CO Ⅰ and CO Ⅱ gene sequences. Software tools such as ClustalX, DnaSP v5.0, and Network v4.6.1.0 were utilized to analyze the genetic differentiation (Fst), gene flow (Nm) among populations of Aedes japonicus, Aedes albopictus and Armigeres subalbatus. Results The mosquito specimens collected from the Wuyi Mountain Nature Reserve were identified as 30 species belonging to 8 genera within the Culicidae family. Among them, there were 10 species of Aedes, 13 species of Culex, 1 species each of Armigeres, Orthopodomyia, Uranotaenia, Tripyeroides, and Anopheles, and 2 species of Toxorhynchites. Analysis of the genetic structure of important mosquito populations showed that the haplotype diversity index (Hd) of Ae. japonicus was 0.994 7, with a generally moderate degree of differentiation between populations and a higher degree of genetic differentiation between populations 6 and 12; Aedeslbopictus had a haplotype diversity index of 0.634 0, with significant genetic differentiation between populations 1 and 2 compared to other groups; Armigeres subalbatus had a haplotype diversity index of 0.703 3, with substantial genetic differentiation and limited gene flow between population 2 and populations 3, 4, 6, and 7. Conclusions The mosquito species are rich in Wuyi Mountain Nature Reserve. A comprehensive survey of the composition and distribution of mosquito populations was carried out, and the characteristics of the population genetic structure of the important species of Ae. japonicus, Ae. Albopictus, and Ar. subalbatus populations were analyzed, providing valuable scientific data reference for local mosquito-borne ecological research and disease prevention and control.

ObjectiveTo analyze the characteristics of hospitalized unintentional injuries and to provide evidence for formulating injury prevention and control strategies. MethodsDescriptive analysis was conducted on injury information of unintentional injury cases reported from 22 monitoring hospitals during 2017 to 2020 by injury surveillance system. The composition ratio index was used to analyze and explore the distribution（population， time and place）of injuries related to different causes. The disease burden was described by the length of hospital stay and hospitalization cost. ResultsA total of 32 716 hospitalized unintentional injury cases were reported from 22 monitoring hospitals. The male to female ratio was 1.18∶1. The majority of males were aged 15‒64 years and the majority of females were aged over 45 years. The top three causes of injuries were falls， traffic-related and blunt injury. Injuries occurred more frequently in July and August. 42.81% of the cases occurred at home. Fracture cases accounted for 75.79%. The median length of hospital stay was 10 days and the median cost was 15 431.50 yuan. The share of both falls and non-motor vehicle accidents increased year by year. ConclusionFalls among elderly people and road traffic injuries are the main causes of hospitalized unintentional injuries， and sharp or blunt instrument injuries are more severe in the male workforce. Considering high direct and indirect economic losses from injuries， steps should to be taken to improve injury surveillance system and to implement injury prevention and control strategies targeted on key groups and key injuries.

Objective:To analyze and compare the survival rate between patients with screen-detected and non-screening detected colorectal cancer in Shanghai from 2013 to 2015. Methods:Patients with screen-and non-screening detected colorectal cancer from 2013 to 2015 were collected from Shanghai Colorectal Cancer Screening Program and the Population-Based Cancer Registry.The results presented were based on data collected by December 31,2020.Survival rates were stratified by year of diagnosis,gender,site,age-group,stage at diagnosis and histopathologic category when analyzed.The 5-year observed survival rates were calculated based on the life table,and then the cumulative expected survival rates were calculated according to the Ederer Ⅱ method.Finally,the 5-year relative survival rate was calculated.The COX proportional hazard regression model was used for the multivariate analysis. Results:2 108 patients with screening-detected colorectal cancer and 14 154 patients with non-screening colorectal cancer from 2013 to 2015 were included in the analysis,and the proportions of phase Ⅰ were 35.53％and 9.33％,respectively.The stage distribution of colorectal cancer was significantly different between patients with screen-detected and non-screening detected colorectal cancer(P＜0.05).The 5-year relative survival rates of patients with screen-detected and non-screening detected colorectal cancer were 84.66％(95％confidence interval:82.87％-86.45％)and 63.51％(95％confidence interval:62.64％-64.38％),respectively.The patients with screen-detected colorectal cancer had a significantly improved 5-year relative survival rate in comparison with the patients with non-screening detected colorectal cancer.The survival rates of females in both groups were higher than those of males.The relative survival rate decreased with the increase of age and gradually decreased with the increase of stage at diagnosis.The relative survival rate of patients with non-screening detected colon cancer was significantly lower than that of patients with rectal cancer. Conclusion:Patients with colorectal cancer found at screening had a significantly improved survival rate compared to patients with non-screening detected colorectal cancer.Staging at diagnosis is a key factor,which indicates that enhancing screening and early diagnosis has important meaning to further improve the survival of patients with colorectal cancer and reduce the burden of disease.

Objective:To predict and analyze the incidence trend of mumps using the Autoregressive integrated moving average model (ARIMA) in Jiangxi Province.Methods:The ARIMA was used to model the number of mumps cases per month from 2015 to 2019 in Jiangxi Province. The number of mumps cases in 12 months was predicted and was compared with the actual reported cases in 2020, 2021, and 2022, respectively.Results:The optimal model was ARIMA (0,2,1)(1,2,0) 12. The predicted number of cases was significantly higher than that reported in 2020, 2021 and 2022. The number of reported cases of mumps in 2020, 2021, and 2022 decreased by 54.02%, 63.40%, and 66.09% compared with the forecast. Conclusions:From 2020 to 2022, the reported incidence of mumps in Jiangxi Province was significantly lower than the predicted incidence. Considering that it was related to non-drug intervention measures and changes in immunization strategies, it was suggested to strengthen mumps surveillance further to better cope with the epidemic situation of mumps.

Schizophrenia is a serious mental disease. The diagnosis of schizophrenia so far relies heavily on subjective evidence, including self-reported experiences by patients, manifestations described by relatives, and abnormal behaviors assessed by psychiatrists. The diagnosis, monitoring of the disease progression and therapy efficacy assessment are challenging due to the lack of established laboratory biomarkers. Based on the current literature, clinical consensus, guidelines, and expert recommendations, this review highlighted evidence-based potential laboratory biomarkers for the diagnosis of schizophrenia, including genetic biomarkers, neurotransmitters, neurodevelopmental-related proteins, and intestinal flora, and discussed the potential future directions for the application of these biomarkers in this field, aiming to provide an objective basis for the use of these biomarkers in the early and accurate diagnosis, treatment, and prognosis and rehabilitation assessment of schizophrenia.

To ensure the safety of medications, it is vital to accurately authenticate species of the Apocynaceae family, which is rich in poisonous medicinal plants. We identified Apocynaceae species by using nuclear internal transcribed spacer 2 (ITS2) and psbA-trnH based on experimental data. The identification ability of ITS2 and psbA-trnH was assessed using specific genetic divergence, BLAST1, and neighbor-joining trees. For DNA barcoding, ITS2 and psbA-trnH regions of 122 plant samples of 31 species from 19 genera in the Apocynaceae family were amplified. The PCR amplification for ITS2 and psbA-trnH sequences was 100%. The sequencing success rates for ITS2 and psbA-trnH sequences were 81% and 61%, respectively. Additional data involved 53 sequences of the ITS2 region and 38 sequences of the psbA-trnH region were downloaded from GenBank. Moreover, the analysis showed that the inter-specific divergence of Apocynaceae species was greater than its intra-specific variations. The results indicated that, using the BLAST1 method, ITS2 showed a high identification efficiency of 97% and 100% of the samples at the species and genus levels, respectively, via BLAST1, and psbA-trnH successfully identified 95% and 100% of the samples at the species and genus levels, respectively. The barcode combination of ITS2/psbA-trnH successfully identified 98% and 100% of samples at the species and genus levels, respectively. Subsequently, the neighbor joining tree method also showed that barcode ITS2 and psbA-trnH could distinguish among the species within the Apocynaceae family. ITS2 is a core barcode and psbA-trnH is a supplementary barcode for identifying species in the Apocynaceae family. These results will help to improve DNA barcoding reference databases for herbal drugs and other herbal raw materials.
