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.

AIM To evaluate the chemical constituent consistency in formula granules and traditional decoctions of Gouteng Jiangya Formula.METHODS HPLC characteristic chromatograms were established,the analysis was performed on a 30 ℃ thermostatic YMC-Triart C18 column(4.6 mm× 250 mm,5 μm),with the mobile phase comprising of acetonitrile-0.2％phosphoric acid flowing at 1.0 mL/min in a gradient elution manner,and the detection wavelength was set at 240 nm.Puerarin was used as an internal standard to calculate the relative correction factors of 3'-methoxy puerarin,puerarin apioside,magnolflorine,paeoniflora,daidzin,baicalin,palmatine,berberine,wogonoside and benzoylpaeoniflorin,after which the content detemination was made by quantitative analysis of multi-components by single-marker(QAMS).RESULTS The characteristic chromatograms of 9 batches of formula granules and 15 bacthes of traditional decoctions demonstrated the similarities of more than 0.90 at the detection wavelengths of 192,210,240,260,280,300,320,360 nm,along with similar total peak areas.Eleven constituents showed good linear relationships within their own ranges(r＞0.999 0),whose average recoveries were 97.27％-101.64％with the RSDs of 0.36％-1.11％,the result obtained by QAMS and external standard method demonstrated no significant differences(P＞0.05).The contents of various constituents in the formula granules approximated those in the traditional decoctions.CONCLUSION The consistent kinds and contents of various constituents are obversable in formula granules and traditional decoctions of Gouteng Jiangya Formula,which can provide a reference for the reasonable clinical application of this formula.

Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

OBJECTIVE: Recaticimab (SHR-1209) significantly reduces low-density lipoprotein cholesterol levels. However, its effect on glucose metabolism remains unclear. This study aimed to evaluate its effect on glycemic parameters in a Chinese population. METHODS: Recaticimab versus placebo was administered in a 5:1 ratio to 110 hyperlipidemia patients who were followed up for 24 weeks. Glycated hemoglobin (HbA1c) levels were measured at baseline every 12 weeks. Fasting plasma glucose (FPG) levels were measured at baseline at week 1, 3, 5, 8, 12, 16, 20, and 24. Repeated-measures mixed-effects models were used to determine the longitudinal association between reacticimab and FPG and HbA1c levels. RESULTS: Among the 81 participants with normal glucose metabolism, HbA1c levels significantly decreased ( F = 4.568, P = 0.036). In the 29 participants with abnormal glucose metabolism, a significant time effect was observed for FPG levels ( F = 2.492, P = 0.016). For participants with normal and abnormal glucose metabolism, no significant group × time interaction effects on FPG or HbA1c levels were identified. CONCLUSION Recaticimab showed no adverse glycemic effects in participants with normal or abnormal glucose metabolism, indicating its safety in patients with or without diabetes.

Objective:To analyze the operational effectiveness of a multi-medication management and consultation service platform for elderly patients based on quality function deployment (QFD) and “Internet+”.Methods:It was a non-randomized controlled trial. A total of 100 elderly patients were selected from the Department of Neurology of the First Affiliated Hospital of Wenzhou Medical University from September to November 2023 with convenience sampling method. The medication management was carried out through the multiple medication management and counseling service platform for the patients based on QFD and “Internet+”. The core modules included reminder module, evaluation module, consultation module and popularization module. A self-designed satisfaction questionnaire was used to collect the satisfaction scores of hospital service quality, medication adherence, medication knowledge, and medication safety before and one month after the platform was implemented. A total of 100 questionnaires were distributed, and 100 valid questionnaires (100%) returned. The t-test was used to analyze the differences between the satisfaction scores before and after the operation of the platform to evaluate the operation effects. Results:Among the 100 elderly patients with multiple medications included in the analysis, 65 were male and 35 were female, 84 patients had a combination of ≥2 chronic diseases. The patients aged (68.73±5.99) years, and the number of medications they were taking was (7.65±1.04). The scores of hospital service quality, medication adherence, medication knowledge, and medication safety after the application of the platform were all significantly higher than those before the launch of the platform [(3.66±0.48) vs (2.91±0.70) points, (3.90±0.30) vs (1.30±0.46) points, (3.39±0.49) vs (3.02±0.63) points, (3.75±0.44) vs (1.48±0.59) points](all P<0.05). Conclusion:The multiple medication management and consultation service platform for elderly patients based on QFD and “Internet+” can enhance the scientific management of multiple medication in elderly patients, reduce the burden of medication, improve the quality of medical services, and promote the development of intelligent elderly care services.

Objective:To compare the clinical efficacy between microscopic varicocelectomy and laparoscopic varicocelectomy in the treatment of varicocele(VC)with male infertility.Methods:A total of 307 patients who were diagnosed with VC complicated with male infertility and admitted to the Affiliated Hospital of Qingdao University from October 2018 to October 2022 were recruited for retrospective analysis.The patients were divided into the microscopic group(180 cases)and laparoscopic group(127 cases)according to the surgery method.The pre-and postoperative clinical data of these two groups were analyzed,including the degree of dilatation and reflux time of internal spermatic vein,hemodynamic parameters of testicular capsular artery,proportion of progressive motility spermato-zoa(PR),concentration of spermatozoa,proportion of normal morphology sperm,the pregnancy outcome of spouses and the incidence of complications related with surgery within 2 years postoperatively.Results:All the surgeries for the 307 patients in this study were successful.There was no significant difference in operation time,hospitalization time and management expenses between the microscop-ic group and the laparoscopic group(P＞0.05).Compared to the patients in laparoscopic group,the patients in the microscopic group received a better improvement in venous diameter,reflux time of spermatic veins and hemodynamic parameters of testicular capsular ar-tery(P＜0.05).Moreover,the semen analysis showed that the PR,spermatozoa concentration and proportion of normal morphology sperm in the microscopic group were also obviously increased than those in the laparoscopic group(P＜0.05).During the 2-year fol-low-up period,the conception rate of spouses in the microscopic group was 67.2％,while only 47.2％in the laparoscopic group,in which the difference was statistically significant(P＜0.05).Besides,the time-to-pregnancy(TTP)within 2 years postoperatively in the microscopic group was significantly shorter than that in the laparoscopic group(P＜0.05).Meanwhile,the incidence of adverse pregnancy outcomes in the microscopic group was also significantly lower than that in the laparoscopic group(P＜0.05).It is worth mentioned that the spontaneous conception rate of spouses with successful pregnancy in the microscopic group was also significantly higher than that in the laparoscopic group(P＜0.05).Severe complication such as testicular atrophy,bleeding and infection did not appear in both of two groups.However,the incidences of testicular hydrocele and recurrence of VC postoperatively in the laparoscopic group were significantly higher than those in the microscopic group(P＜0.05).Conclusion:Both microscopic varicocelectomy and laparoscopic varicocelectomy can be applied to the management of VC combined with male infertility.But microscopic varicocelectomy showed better clinical efficacy in improving the testicular hemodynamic parameters,semen quality,pregnancy outcome and postopera-tive complications,which is worthy of further clinical applications.

Aim To investigate the effects of breast cancer-related depression model on microglial activa-tion and neuronal function via the NLRP3-COX-2 sig-naling pathway.Methods In the cell experiment,BV2 and HT22 cells were co-cultured to observe the polarization of BV2 cells and the injury of HT22 cells.In the animal experiment,behavioral experiments were used to evaluate the depressive behaviors of mice.HE staining and tumor weight were used to evaluate the changes of axillary tumors.ELISA was used to detect the contents of CA153,CA125,CEA,as well as the changes in the contents of 5-HT,DA and others in the serum and hippocampus.RT-qPCR and immunohisto-chemistry were used to detect the mRNA and protein expression of IL-1 β,IL-18 and other indicators,re-spectively.Immunofluorescence was used to detect CD1 1b and Iba-1.Nissl staining and transmission elec-tron microscopy were used to observe the hippocampal neurons.Results The results of cell experiments showed that compared with the model group,the pro-tein contents and mRNA expression levels of NLRP3,COX-2,and IL-1 β in the NLRP3 knockdown group were all decreased.The results of animal experiments showed that compared with the model group,the be-havioral performance of the experimental group was im-proved,and the mRNA and protein expression levels of IL-1 β,IL-18,and NLRP3 were decreased.Conclu-sion BCRD may mediate the polarization of microglia and the injury of hippocampal neurons through the NL-RP3-COX-2 signaling pathway.

Soy is a vital source of plant carbohydrates.However,it poses significant allergenic risks,particularly to young children and animals.Among the various proteins in soy,β-conglycinin,which con-stitutes approximately 30％of total soy carbohydrates,is a primary allergen.Undigested β-conglycinin can lead to intestinal damage by inhibiting cell growth,disrupting the cytoskeleton,and inducing apopto-sis.It can also enter the lymphatic and circulatory systems,triggering allergic reactions.Conventional ELISA methods for detecting β-conglycinin rely on polyclonal or monoclonal antibodies,which are limited by their large molecular weight,difficulty in accessing the protein core,and sensitivity to acidic and bas-ic conditions.To address these limitations,this study aimed to develop nanobodies(Nbs)against β-con-glycinin.Nbs,derived from the variable regions of heavy-chain antibodies found in camelids,have a mo-lecular weight approximately one-tenth that of conventional antibodies.They offer advantages such as small size,stable structure,high specificity,and strong affinity.A female alpacas was immunized five times using β-conglycinin,which showed a heavy chain antibody potency of 1∶16 000 by ELISA.Pe-ripheral blood lymphocytes were subsequently isolated and total RNA was extracted.The variable region of the heavy-chain antibody was amplified via PCR,and recombinant plasmids were constructed and transformed into the E.coli competency strain ER2738.The resulting library contained about 3.5×108 CFU/mL,which increased to 1.15×1012 PFU/mL after phage rescue,with a 100％Nbs gene insertion rate,indicating high diversity.Its Nbs phage output was significantly enriched by four rounds of solid-phase elution with an enrichment rate of 155.9.Four rounds of solid-phase panning yielded 35 positive clones,all of which shared the same amino acid sequence upon sequencing.The selected Nb was ex-pressed in a prokaryotic system,and its binding ability to β-conglycinin was confirmed using Western blotting and ELISA.The results demonstrated excellent specificity and affinity.This research lays the groundwork for developing a rapid and efficient detection method for β-conglycinin using Nbs,potentially enhancing food safety and allergen management.
