Objective To gain insights into the biological characteristics of different populations of Culex tritaeniorhynchus within and around the Yellow Sea wetland from the perspective of the occurrence of resistance, we investigated the levels of resistance to deltamethrin and kdr gene mutation in the wetland and its peripheral areas. Methods Specimens were collected from Cx. tritaeniorhynchus populations at two monitoring sites in the Rare Bird National Nature Reserve and Tiaozi Ni Wetland Scenic Area, and also from two populations in Yancheng City and the Liuhe District of Nanjing, and the resistance of these mosquitoes to deltamethrin was determined using the CDC biotest bottle method. For each concentration of deltamethrin assessed, a random subset of exposed specimens was selected for amplification of the kdr gene fragment, followed by Sanger sequencing to identify and analyze resistance-associated mutations. Results The LC50 levels of deltamethrin among mosquitoes from the four populations in Luhe, Yancheng, the Rare Bird National Nature Reserve and the Tiaozi Ni Wetland Scenic Area were 2.048 5, 7.798 2, 3.473 3, and 17.695 5 mg/mL, respectively, with corresponding concentrations of deltamethrin ranging from 0.005 to 5.000,0.050 to 50.000,0.050 to 25.000 and 0.050 to 50.000 mg/mL, respectively. Furthermore, the ranges of the KT50 values were 11.76-107.43, 67.05-216.30,29.77-107.43 and 28.40-329.51 min; the 1-h knockdown rates were 34.58%-99.15%, 9.52%-43.80%, 55.09%-73.01%, and 10.09%-68.07%; and the 24-h mortality rates were 12.15%-67.52%,9.52%-79.56%,13.17%-82.21%, and 11.01%-78.99%, respectively. With respect to kdr gene mutation, we assayed a total of 63,70,59, and 57 mosquitoes for the four populations, for which we detected L1014F mutation frequencies of 14.29%, 35.00%, 20.34%, and 31.58%, respectively, with a majority of these mutations being heterozygous for resistance. In addition, five adult mosquitoes were identified has having synonymous mutations at site 1011[i. e. , AAT(asparagine)mutation to AAC(asparagine)]. Conclusions Our findings revealed the clear resistance of Cx. tritaeniorhynchus to deltamethrin in the Yancheng region of the Yellow Sea wetland, and the resistance phenotype and kdr frequency of Cx. tritaeniorhynchus in the wetland environment were comparable to those of Cx. tritaeniorhynchus in the wetland environment, thereby indicating that the resistance of different populations of Cx. tritaeniorhynchus was homogeneous under the pressure of different insecticide selection within and around the wetland. However, the underlying mechanisms need to be further studied.

Objective:To explore the clinical efficacy of transcranial ultrasound stimulation combined with low-frequency neuromuscular electrical stimulation on the treatment of cognitive and motor function deficits in stroke patients.Methods:Ninety patients with cerebral hemorrhage in the rehabilitation department from July 2023 to July 2024 were selected and divided into control group( n=44)and observation group( n=46)randomly.The control group received conventional rehabilitation methods and low-frequency neuromuscular electrical stimulation rehabilitation treatment, while the observation group received transcranial ultrasound treatment in addition.Mini-mental state examination (MMSE), simplified Fugl-Meyer assessment (SFMA), modified Barthel index (MBI) and Brunnstrom movement therapy phase were used to evaluate the effectiveness of cognitive and motor rehabilitation treatment for all stroke patients.The data were analyzed by paired t-test, independent sample t-test, and Mann-Whitney U test using SPSS 26.0 software. Results:After treatment, the scores of MMSE (observation group: 26.12±2.24, control group: 23.08±1.56), SFMA(observation group: 24.83±9.02, control group: 17.24±9.51), and MBI(observation group: 68.00±7.03, control group: 49.66±7.98) of both groups were significantly higher than those before treatment(MMSE(observation group: 21.32±2.11, control group: 21.56±1.96), SFMA(observation group: 10.43±8.05, control group: 10.56±7.63), MBI (observation group: 32.34±7.65, control group: 32.00±9.73)), and the differences were all statistically significant ( t=-18.13--2.31, all P<0.05).The scores of MMSE, SFMA, and MBI in observation group were all higher than those of the control group, with statistically significant differences( t=-4.45, -4.51, -5.59, all P<0.05). After treatment, the observation group had more patients with Brunstrom stage Ⅳ or above in the affected upper limb ( Z=-6.236, P=0.045) and lower limb ( Z=-6.589, P=0.036) compared to the control group. There were more patients in both two groups with grade Ⅳ or above in the affected lower limb than in the affected upper limb ( P<0.05). Conclusion:The combination of transcranial ultrasound stimulation therapy and low-frequency neuromuscular electrical stimulation therapy can significantly improve cognitive and motor dysfunction in stroke patients. It can be used for the rehabilitation treatment of cognitive and motor dysfunction in stroke patients.

Objective To investigate the relationship of benign prostatic hyperplasia(BPH) with abnormal glucose and lipid metabolism in the elderly. Methods A total of 152 elderly patients with BPH were selected as study subjects. The levels of fasting plasma glucose (FPG), 2-hour postprandial glucose (2 hPG), fasting insulin (FINS), total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), blood uric acid (UA), and prostate-specific antigen (PSA) were measured. Their systolic blood pressure (SBP) and diastolic blood pressure (DBP) were also measured. Prostate volume (PV) and annual prostate growth rate were calculated, and the International Prostate Symptom Score (IPSS) was assessed. Based on blood glucose, blood lipids, and IPSS, the patients were divided into normal blood glucose group(99 cases) and hyperglycemia group(53 cases), normal blood lipid group(112 cases) and dyslipidemia group(40 cases), and moderate symptom group(91 cases) and severe symptom group(61 cases). The clinical characteristics of patients in each group were compared, and the relationships of abnormal glucose and lipid metabolism with the severity of lower urinary tract symptoms in patients with BPH were analyzed. Results Compared with the normal blood glucose group, patients in the hyperglycemia group had higher age, SBP, annual prostate growth rate, IPSS, and levels of FPG, 2 hPG, FINS, and PSA, larger PV, and lower HDL-C level (

Background::The correlation between metals and hypertension, such as sodium, zinc, potassium, and magnesium, has been confirmed, while the relationship between aluminum and hypertension is not very clear. This study aimed to evaluate the correlation between plasma aluminum and hypertension in electrolytic aluminum workers by the Bayesian networks (BN).Methods::In 2019, 476 male workers in an aluminum factory were investigated. The plasma aluminum concentration of workers was measured by inductively coupled plasma mass spectrometry. The influencing factors on the prevalence of hypertension were analyzed by the BN.Results::The prevalence of hypertension was 23.9% in 476 male workers. The risk of hypertension from plasma aluminum in the Q2, Q3, and Q4 groups was 5.20 (1.90-14.25), 6.92 (2.51-19.08), and 7.33 (2.69-20.01), respectively, compared with that in the Q1 group. The risk of hypertension from the duration of exposure to aluminum of >10 years was 2.23 (1.09-4.57), compared without aluminum exposure. Area under the curve was 0.80 of plasma aluminum and the duration of exposure to aluminum was based on covariates, indicating that aluminum exposure had important predictive value in the prevalence of hypertension in the occupational population. The results of the study using the BN model showed that if the plasma aluminum of all participants was higher than Q4 (≥47.86 μg/L) and the participants were drinking, smoking, diabetes, central obesity, dyslipidemia, and aged >50 years, the proportion of hypertension was 71.2%.Conclusions::The prevalence of hypertension increased significantly with the increase of plasma aluminum level.

Both anti-glomerular basement membrane (GBM) disease and the anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) are common causes of pulmonary-renal syndrome. Organizing pneumonia (OP), a special pattern of interstitial lung disease, is extremely rare either in AAV or anti-GBM disease. We report an old woman presented with OP on a background of co-presentation with both ANCA and anti-GBM antibodies.

This study analyzed the anemia status and change trend of 219 835 pregnant women in eight provinces from 2016 to 2020 in the Maternal and Newborn Health Monitoring Program(MNHMP). The results showed that from 2016 to 2020, the anemia rate of pregnant women in eight provinces was 41.27%, and the rates of mild, moderate and severe anemia were 28.56%, 12.59% and 0.12% respectively; the anemia rates in eastern, central and western regions were 41.87%, 36.09% and 44.63% respectively, and the anemia rates in urban and rural areas were 39.87% and 42.23%. From 2016 to 2020, the anemia rate of pregnant women decreased from 44.93% to 38.22%, with an average annual decline of 3.86% (95%CI:-5.84%, -1.85%). The anemia rate among pregnant women of the eastern region (AAPC=-6.16%, 95%CI:-9.79%, -2.38%) fell faster than that among pregnant women of the central region (AAPC=0.71%, 95%CI:-6.59%, 8.57%) and western region (AAPC=-1.53%, 95%CI:-5.19%, 2.28%). From 2016 to 2020, the moderate anemia rate in pregnant women decreased from 14.98% to 10.74%, with an average annual decline of 8.72% (95%CI:-12.90%, -4.34%), with a statistically significant difference (P<0.05); AAPC for mild and severe anemia in pregnant women was 1.56% (95%CI: 3.44%, 0.36%) and 18.86% (95%CI: 39.88%, 9.52%), respectively, without statistically significant difference (P>0.05).

Recent population studies have significantly advanced our understanding of how age shapes the gut microbiota.However,the actual role of age could be inevitably confounded due to the complex and variable environmental factors in human populations.A well-controlled envi-ronment is thus necessary to reduce undesirable confounding effects,and recapitulate age-dependent changes in the gut microbiota of healthy primates.Herein we performed 16S rRNA gene sequenc-ing,characterized the age-associated gut microbial profiles from infant to elderly crab-eating maca-ques reared in captivity,and systemically revealed the lifelong dynamic changes of the primate gut microbiota.While the most significant age-associated taxa were mainly found as commensals such as Faecalibacterium,the abundance of a group of suspicious pathogens such as Helicobacter was exclusively increased in infants,underlining their potential role in host development.Importantly,topology analysis indicated that the network connectivity of gut microbiota was even more age-dependent than taxonomic diversity,and its tremendous decline with age could probably be linked to healthy aging.Moreover,we identified key driver microbes responsible for such age-dependent network changes,which were further linked to altered metabolic functions of lipids,carbohydrates,and amino acids,as well as phenotypes in the microbial community.The current study thus demon-strates the lifelong age-dependent changes and their driver microbes in the primate gut microbiota,and provides new insights into their roles in the development and healthy aging of their hosts.
