ObjectiveTo analyze the temporal trend of knockdown resistance (kdr) gene mutations highly correlated with pyrethroid resistance in field populations of Aedes aegypti in Jinghong City of Yunnan Province, and to provide a scientific basis for formulating rational insecticide use strategies. MethodsAdult mosquito samples of Aedes aegypti from 2016 to 2023 and larvae mosquito samples from July 2022 to June 2023 were collected in Jinghong City of Yunnan Province. Allele specific PCR (AS-PCR) was used to measure kdr mutations at amino acid positions 989, 1016 and 1534 of the voltage-gated sodium ion channel (VGSC) gene. Data such as mutation rate and mutation allele frequency were calculated, SPSS software was used to perform trend chi square tests on mutation rate and mutation allele frequency with year and month, as well as comparison of mutation allele frequencies and genotype distributions between the dry and rainy seasons, thereby delineating the temporal trend of kdr gene mutations. ResultsAmong the 173 samples collected from 2016 to 2023, the mutation rates of S989P and V1016G were 100.00% for each year, while the mutation rate of F1534C ranged from 62.50% to 100.00%. The mutation rate and mutation allele frequency of F1534C were increased over the years (χ²=22.079, P<0.001; χ²=42.971, P<0.001). Concurrently, the proportion of the PPGGCC genotype was increased annually (χ²=60.790, P<0.001). Among the 288 samples collected from July 2022 to June 2023, the monthly mutation rates for S989P, V1016G, and F1534C were consistently 100.00%. There was only one type of mutation present, namely S989P+V1016G+F1534C. In the combinations of the three genotypes, the SPGGCC genotype accounted for 1.39% (4/288), the PPGGFC accounted for 2.78% (8/288), and the PPGGCC had the highest proportion at 95.83% (276/288). After tesiting the samples collected in August 2023, the mutation rates of 989, 1016 and 1534 sites of VGSC in females, males, and larvae of the same generation were all 100.00%. ConclusionSince 2016, the gene mutations at S989P and V1016G loci in the VGSC gene of wild Aedes aegypti in Jinghong City have remained consistently at 100.00%, while the mutation rate and mutant allele frequency of F1534C have increased year by year during the testing period. By 2023, the mutation rates at three loci in the VGSC gene of Aedes aegypti in Jinghong City had all reached 100.00%, and neither changes in insect developmental stage nor gender differences during transmission exerted a detectable impact on the mutation rates. In the control of Aedes aegypti in Jinghong City, the use of pyrethroid insecticides should be stopped or reduced, and regular monitoring of kdr genes should be carried out to promptly detect new mutations.

Objective To explore the neuroprotective effect and related mechanism of electroacu-puncture(EA)combined with tanshinone Ⅱ A(Tan ⅡA)for the treatment of rats with cerebral ische-mia-reperfusion(I/R)injury.Methods Model rats with cerebral I/R were established by the modi-fied Longa suture occlusion method and randomly divided into Model group,EA group,Tan Ⅱ A group,and EA+Tan Ⅱ A group,with 16 rats in each group.Rats in the Sham group(n=16)had their carotid arteries exposed and dissected but not occluded.Neurological deficit score and Morris wa-ter maze test were used to assess neurological impairment and cognitive function in rats.2,3,5-triph-enyltetrazolium chloride(TTC)staining was used to evaluate cerebral infarction volume.Hematoxylin-eosin(HE)staining and TUNEL staining were used to assess neuronal damage in the hippocampus.Western blot was used to detect apoptosis-related proteins and proteins related to the Hippo signaling pathway.Results Compared with the Sham group,the Model group showed increased neurological deficit score,percentage of cerebral infarction area,escape latencies during acquisition training,proportion of TUNEL-positive stained cells in brain tissue,Caspase-3 activity,expression of Cleaved Caspase-3 protein and Bax protein,and decreased expression of time spent in the target quadrant during probe training,the number of platform crossings within 60 s,Bcl-2 protein,Yes-associated protein(YAP),and transcriptional co-activator with PDZ-binding motif(TAZ)protein,and all the differences were significant(P＜0.05).Compared with the Model group,the EA group,Tan Ⅱ A group,and EA+Tan Ⅱ A group showed decreased neurological deficit score,percentage of cerebral infarction volume,escape latencies during acquisition training,time spent in the target quadrant during probe training,number of platform crossings within 60 s,proportion of TUNEL-positive stained cells in brain tissue,Caspase-3 activity,expression of Cleaved Caspase-3 protein and Bax protein,with the EA+Tan Ⅱ A group showing lower values than the EA group and Tan Ⅱ A group,and all the differences were significant(P＜0.05).Compared with the Model group,the EA group,Tan Ⅱ A group,and EA+Tan Ⅱ A group showed increased expression of Bcl-2,YAP,and TAZ proteins,with the EA+Tan Ⅱ A group showing higher protein expression levels than the EA group and Tan Ⅱ A group,and all the differences were significant(P＜0.05).Conclusion The combination of EA and Tan Ⅱ A for the treatment of cerebral I/R injury exhibits synergistic effect,and its mechanism may be related to the inhibition of Hippo pathway activity.

Objective To investigate the influencing factors of adverse pregnancy outcomes in patients with preeclampsia and the predictive value of serum trace elements in the second trimester.Methods A total of 98 patients with preeclampsia admitted to Qujing First People's Hospital from January 2019 to June 2022 were enrolled in the study.Patients were divided into poor outcome group and good outcome group according to whether they had adverse pregnancy outcomes.The clinical data of all patients enrolled in the study were col-lected and the serum levels of trace elements calcium,copper,zinc and iron were detected in the second trimes-ter.Univariate analysis and multivariate Logistic regression were used to analyze the influencing factors of ad-verse pregnancy outcomes in patients with preeclampsia.The levels of serum trace elements in the second tri-mester of pregnancy were compared between the poor outcome group and the good outcome group.The re-ceiver operating characteristic(ROC)curve was used to evaluate the predictive value of serum trace elements calcium,copper,zinc and iron for adverse pregnancy outcomes in patients with preeclampsia.Results Univari-ate analysis showed that compared with the good outcome group,the poor outcome group had significantly higher systolic blood pressure,24 h urinary protein quantitation,and D-dimer level(P＜0.05)and significantly less gestational age and platelet count at admission(P＜0.05).Multivariate Logistic regression analysis showed that 24 h urinary protein quantification,D-dimer and platelet count were the influencing factors of ad-verse pregnancy outcomes in patients with preeclampsia(P＜0.05).The levels of serum trace elements calci-um,copper,and zinc in the poor outcome group were significantly lower than those in the good outcome group(P＜0.05),and the level of iron was significantly higher than that in the good outcome group(P＜0.05).ROC curve analysis showed that the areas under the curves(AUCs)of serum calcium,copper,zinc,and iron in the second trimester of pregnancy for predicting adverse pregnancy outcomes in preeclampsia patients were 0.830(95％CI:0.780-0.880),0.855(95％CI:0.805-0.905),0.847(0.797-0.897)and 0.861(95％CI:0.811-0.911),respectively.Conclusion Adverse pregnancy outcomes in patients with preeclampsia are re-lated to 24 h urine protein,D-dimer and platelet count.The levels of serum trace elements calcium,copper,zinc and iron in the second trimester of pregnancy change significantly in patients with adverse pregnancy out-comes,which may become predictive markers of adverse pregnancy outcomes.

Objective To investigate the correlation between claudin-5 level and the risk of hemor-rhagic transformation(HT)in elderly stroke patients after thrombolysis.Methods A total of 192 elderly stroke patients hospitalized in our department from February 2021 to October 2022 were recruited,and divided into HT group(32 cases,including 14 of parenchymal hematoma type and 18 of hemorrhagic cerebral infarction type)and non-HT group(160 cases)according to the results of head CT or MRI 48 h after thrombolysis.The clinical data and serum claudin-5 level were com-pared between the two groups.Multivariate logistic regression analysis was used to identify the in-fluencing factors of HT risk after thrombolysis in elderly stroke patients.Restricted cubic splines were drawn to analyze the correlation between claudin-5 level and HT risk after thrombolysis.Re-sults The HT group had higher proportion of atrial fibrillation,longer onset to thrombolysis time,higher baseline NIHSS score,and fasting blood glucose and claudin-5 levels than the non-HT group(P＜0.05,P＜0.01).Multivariate logistic regression analysis showed that time from onset to thrombolysis(OR=2.589,95％CI:1.202-5.573,P=0.015),baseline NIHSS score(OR=1.415,95％CI:1.213-1.651,P=0.000),and fasting blood glucose(OR=1.552,95％CI:1.014-2.375,P=0.043)and claudin-5 levels(OR=1.174,95％CI:1.076-1.281,P=0.000)were risk factors for HT after thrombolysis in elderly stroke patients.Restricted cubic spline anal-ysis demonstrated that claudin-5 level had a nonlinear relationship with the risk of HT in the pa-tients after thrombolysis(x2=12.380,P=0.006).Conclusion Serum claudin-5 level is associated with HT after thrombolysis in elderly stroke patients,and shows a dose-response relationship with HT.

Objective:To investigate the effect of triglyceride-glucose index (TyG) on the severity of depression in patients with depression.Methods:The clinical data of 653 patients with depression admitted to Hebei General Hospital from January to December 2021 were retrospectively analyzed. The patients were categorized into mild-moderate depression group ( n=324) and severe depression group ( n=329) according to the 17-item Hamilton depression scale (HAMD-17) score. Patients' demographics and data on fasting plasma glucose (FPG), triglyceride (TG), total cholesterol, high-density lipoprotein, and low-density lipoprotein were extracted from the electronic medical records, and TyG was calculated. Statistical analyses were performed by SPSS 25.0 software.The Mann-Whitney U test was used to compare the differences between the two groups. Spearman correlation analysis and binary Logistic regression analysis were used to investigate the relationship between TyG level and depression severity. Results:(1) In the severe depression group, FPG( 956.9 (118.9) mg/L vs 865.0 (1 44.2) mg/L), TG(1 275.8 (1 027.8) mg/L vs 983.5 (766.4) mg/L), total cholesterol (2 007.0 (477.6) mg/L vs 1 730.5 (547.2) mg/L), high-density lipoprotein (514.3 (168.2) mg/L vs 464.0 (138.2) mg/L), low-density lipoprotein (1 264.5 (326.8) mg/L vs 1 088.6 (412.8) mg/L), and TyG (8.72 (0.77) vs 8.37 (0.78)) were higher than those in the mild-moderate depression group, and the differences were statistically significant (all P<0.05).(2) Both TyG level and HAMA score were positively correlated with HAMD-17 score ( r=0.231, 0.586, both P<0.05); (3) The results of binary logistic regression analysis showed that TyG ( B=1.116, OR=3.054, 95% CI=2.058-4.531, P<0.05) was a risk factor for the severity of depression in patients with depression. Conclusion:The higher the TyG, the more severe the severity of depression in patients. Insulin resistance may affect the severity of depression in patients with depression.

Mastering and making good use of the advantages and characteristics of communication in the all-media era will also provide more motivation and possibilities for strengthening ideological work. This paper expounded the significance of strengthening the dissemination of socialist ideology in hospitals, proposed the opportunities and challenges faced by hospitals in strengthening the dissemination of socialist ideology in the all-media era, and then put forward specific coping strategies combined with the actual situation of hospitals.

Traditional Chinese Medicine (TCM) treating allergic diseasesis effective and with few adverse reactions. The effects of TCM compound, TCM extracts and Chinese herbal monomers played the anti-allergic role in multiple stages. Such as reducing and preventing target cell degranulation, releasing biologically active mediators, and inhibiting the conduction of signal pathways. Recent studies have found that in addition to anti-allergic effects by regulating cellular and humoral immunity, TCM can also enhance the body’s non-specific immune function to different degrees and help eradicate certain intractable allergic diseases. The development of new therapeutic agents for allergic diseases with good effect and less adverse reactions from Chinese herbal medicine will become a trend in the future research and have broad medical prospects.

Objective:To explore the current status of deep vein thrombosis (DVT) prevention and nursing in Department of Orthopedics of China hospitals, and provide a basis for hospitals and related departments to promote systematic DVT prevention and nursing management.Methods:This study was a cross-sectional study, and convenience sampling method was used. In September 2019, the self-designed Domestic Orthopedic Deep Vein Thrombosis Prevention and Nursing Questionnaire was used to investigate the members of the Orthopedic Nursing Professional Committee who signed up for the China Health Promotion Foundation Orthopedic Venous Thromboembolism (VTE) Prevention and Nursing Management Forum. The survey subject came from 125 hospitals in 29 provinces, municipalities and autonomous regions across the country. Respondents completed the electronic questionnaire survey by scanning the quick response code, and 118 valid questionnaires were finally recovered.Results:The proportion of 118 hospitals carrying out in-hospital DVT special training was 82.2% (97/118) . Among the ways for nurses to acquire knowledge, the exchanges outside the hospital, literature review, and international exchange accounted for 70.3% (83/118) , 60.2% (71/118) and 14.4% (17/118) respectively. The proportion of establishing hospital DVT risk early warning information system was 57.6% (68/118) . The hospital-level professional group formulated a complete DVT prevention and nursing system process accounting for 44.1% (52/118) , and the department-level professional group formulated a complete DVT prevention and nursing system process accounting for 36.4% (43/118) . In the comprehensive evaluation of DVT prevention and nursing management, 65.3% (77/118) of hospitals rated it as excellent, and 34.7% (41/118) of hospitals rated it as fair and lacking.Conclusions:The Department of Orthopedics of China hospitals attaches great importance to DVT prevention, but in the construction of DVT prevention and nursing management system for orthopedic patients, the popularization of DVT risk early warning information system, the application of DVT preventive equipment measures, the improvement of DVT prevention and nursing related systems, and the implementation of professional management specifications needs to be further strengthened.
