Objective:To investigate the relationship between FA,ET-1,Hcy and VEGF in patients with pregnancy induced hypertension.Methods:Selected 80 cases of patients with pregnancy induced hypertension who were treated in our hospital from January 2013 to September 2016,divided into A group (40 cases),and preeclampsia and preeclampsia B group (40 cases),60 cases of normal late pregnant women as C group,60 cases of normal non pregnant women as D group.The plasma levels of FA,ET-1,Hcy and VEGF in each group were detected,and the correlation analysis was performed.Results:The plasma levels of FA and VEGF of group B were lowest in the four groups (P<0.05),the plasma ET-1 and Hcy levels of group B were highest (P<0.05).The plasma FA and VEGF levels of women with pregnancy induce hypertension were lower than those of the healthy late pregnant women.The plasma ET-1 and Hcy levels were higher (P<0.05).The multivariate logistic regression analysis showed that FA,ET-1,Hcy and VEGF levels were risk factors for pregnancy induce hypertension.Conclusion:The elevation of plasma Hcy level caused by FA deficiency in pregnancy might be related to the development of the disease and the incidence of pregnancy induced hypertension syndrome,VEGF might be an important factor in the occurrence and development of pregnancy induced hypertension syndrome.

Objective:The result of influenza etiology surveillance in Chuxiong prefecture were analyzed to master the epidemic characteristics of influenza virus and provide scientific basis for influenza prevention and control.Methods:Real-time PCR assay and MDCK cell culture method were used to detect and separate influenza virus nucleic acids from influenza-like cases (ILI) and suspected influenza cases from 2017 to 2022 come from the sentinel hospitals.Results:From 2017 to 2022, a total of 7 302 cases of ILI and 1 079 cases were detected positive, with a positive rate of 14.78%. The positive rate in the six years was 14.71%、15.44%、20.11%、5.04%、10.90% and 21.08%, and the positive rate in 2020 was the lowest. Among them, the positive rate of influenza A was higher than that of influenza B, and higher in spring and winter than in summer and autumn., One H9N2 human infected with avian influenza virus was detected positive.The outbreak cases were mainly influenza B, followed by influenza A H3N2, and students were susceptible to it. The proportion of influenza-like cases in the 0~5 year old group was the highest (64.16%), and the protortion in 60~year old group was the lowest (0.05%).Conclusions:From 2017 to 2022, influenza A was predominant in Chuxiong prefecture, with high prevalence in winter and spring. The influenza strains presented diversity and each strain circulated alternately. The implementation of COVID-19 prevention and control measures can effectively reduce the infection rate of influenza virus .In addition, there are human cases of avian influenza infection in Chuxiong prefecture. So the surveillance of influenza-like cases should be strengthened an improved, and to expand the monitoring of human and avian influenza.

ObjectiveTo investigate the correlation between genetic polymorphism of heat shock proteins 70 (HSP70) and susceptibility to occupational noise-induced hearing loss (ONIHL). Methods A total of 229 ONIHL workers were selected as the case group and 229 healthy workers with similar age, years of noise exposure, and noise exposure levels were selected as the control group using the case-control study method. Occupational health examinations were conducted on both groups, and peripheral blood of individuals was collected for DNA extraction. The genotypes of three single nucleotide polymorphisms of the HSP70 were detected using the MassArray system. Results The allele frequency distribution of HSP70 rs2227956, rs1043618, and rs1061581 in the control group was in Hardy-Weinberg equilibrium (all P>0.05). The genotype and allele frequency distribution of rs2227956 was significantly different between the two groups (all P<0.05), while no significant difference was found for rs1043618 and rs1061581 (all P>0.05). After adjusting for age, years of noise exposure, individual noise exposure level, smoking, and drinking, individuals with AG and AG+GG genotypes of rs2227956 had a higher risk of ONIHL than those with AA genotype (all P<0.05). The risk of ONIHL was higher in individuals with G allele of rs2227956 than in those with A allele (P<0.05). No correlation was found between rs1043618 and rs1061581 polymorphisms and the risk of ONIHL (all P>0.05). Conclusion The rs2227956 polymorphism of the HSP70 gene is correlated with susceptibility to ONIHL in noise-exposed workers, and the G allele is a risk factor for ONIHL in this population.

Objective:To explore the organizational identity, sense of coherence, perceived social support, and work engagement of surgical nurses in a traditional Chinese medicine hospital and the relationships between them.Methods:From March to May 2022, 450 surgical nurses were selected by convenience sampling from Guangdong Provincial Hospital of Traditional Chinese Medicine for a survey with a general information questionnaire, the Organizational Identification Scale, the Sense of Coherence Scale, the Perceived Social Support Scale, and the Utrecht Work Engagement Scale-9. SPSS 24.0 was used to perform Pearson correlation analysis. AMOS 24.0 was used for structural equation modeling.Results:The nurses' scores of organizational identity, sense of coherence, perceived social support, and work engagement were (26.00±5.00), (53.58±7.50), (47.47±7.50), and (30.06±1.00), respectively. The correlation analysis revealed positive correlations between organizational identity, sense of coherence, perceived social support, and work engagement ( r=0.369-0.741, all P<0.001). Sense of coherence played a partial mediating role between perceived social support and work engagement, and the mediating effect was 0.07, accounting for 12.07% of the total effect. Organizational identity and sense of coherence produced a chain mediating effect between perceived social support and work engagement, in which the mediating effect was 0.11, accounting for 18.97% of the total effect. Conclusions:Organizational identity and sense of coherence produce a chain mediating effect between perceived social support and work engagement in the surgical nurses of the traditional Chinese medicine hospital.

OBJECTIVETo identify potential mutation of TRAPPC2 gene in a Chinese family affected with X-linked spondyloepiphyseal dysplasia tarda (X-SEDL), and explore its underlying molecular mechanism.
METHODSPeripheral blood samples were collected from 32 members of the family and 50 healthy adults to extract genomic DNA. DNA sequences of exons 3 to 6 and their exon/intron boundaries were amplified with PCR amplification. Direct bi-directional sequencing analysis was performed on the PCR products. The sequences were aligned to the reference sequences from the GenBank to determine mutation site and type.
RESULTSA nucleotide substitution of the splice-donor in TRAPPC2 intron 3, c.93+5G>A, was detected in the proband, but no sequence change was detected in TRAPPC2 exons 3 to 6. All of the 6 male patients and 8 female carriers from the family were detected to have carried this mutation. The same mutation was not found in the remaining 18 family members with a normal phenotype and 50 healthy controls.
CONCLUSIONWe have detected a c.93+5G>A mutation in the TRAPPC2 gene in a Chinese family affected with X-SEDL. Our results have expanded the spectrum of TRAPPC2 mutations and is helpful for presymptomatic and prenatal diagnoses of this disease.

To construct, express and purify Exendin-4 analogue and detect its biological activity in vivo. Insert gene sequence into fusion partner ofpED plasmid which is helped to purification, entitled the new recombinant plasmid 5 Exendin-4 analogue polypeptide gene and fusion partner gene was linked by acid hydrolysisgene, transformed to E. coli BL21 and the fusion protein was induced by lactose. After acid hydrolysis, the Exendin-4 analogue polypeptide separated from fusion chaperon. Anion charge chromatography were used to further purification. 6 to 8 week-old ICR mice were injected (s.c) with Exendin-4 analogue, blood glucose and plasma insulin level was detected in different period after oral glucose tolerance test. The results show that high expression of inclusion body was induced by lactose, which accounted for 40% of germ proteins, the Exendin-4 analogue was obtained with the purity of 91.8% after being purified by anion charge chromatography. Bioactivity assay showed that the level of blood glucose of mouse which treated with exendin-4 analogue was obviously decreased to normal (P < 0.01), and the level of plasma insulin was increased obviously (P < 0.01).
