Objective In order to understand the current resistance status of Aedes albopictus(Ae. albopictus) adult population to commonly used insecticides and the resistance dynamics development in Zhejiang Province and provide a theoretical basis for the scientific and rational use of hygienic insecticides. Methods Resistance determination was carried out using the diagnostic dose method(GB/T 26347-2010)recommended by WHO in the adult mosquito contact cylinder method to monitor the resistance of Ae. albopictus field populations in 11 cities and districts in Zhejiang Province in 2024. Results The monitoring result showed that adult Ae. albopictus in 11 areas were resistant or suspected resistant populations to both cis-cypermethrin and permethrin; suspected and resistant populations to the organophosphate insecticide malathion were as high as 81.82%; while suspected resistance to the carbamate insecticide residual carbofuran accounted for 45.45%, and the rest of the monitoring sites were sensitive to it. Conclusions The result suggest that the generalized resistance of Ae. albopictus populations to pyrethroids and organophosphorus insecticides in the field in Zhejiang Province needs to be highly emphasized. In future mosquito vector and mosquito-borne disease control, insecticides should be selected based on the resistance monitoring information, while following scientific guidelines for insecticide use.

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.

ObjectiveTo elucidate the critical role of rehabilitation medical records (including electronic records) in rehabilitation medicine's clinical practice and management, comprehensively analyzed the structure, core content and data standards of rehabilitation medical records, to develop a standardized medical record data architecture and core dataset suitable for rehabilitation medicine and to explore the application of rehabilitation data in performance evaluation and payment. MethodsBased on the regulatory documents Basic Specifications for Medical Record Writing and Basic Specifications for Electronic Medical Records (Trial) issued by National Health Commission of China, and referencing the World Health Organization (WHO) Family of International Classifications (WHO-FICs) classifications, International Classification of Diseases (ICD-10/ICD-11), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Interventions (ICHI Beta-3), this study constructed the data architecture, core content and data standards for rehabilitation medical records. Furthermore, it explored the application of rehabilitation record summary sheets (home page) data in rehabilitation medical statistics and payment methods, including Diagnosis-related Groups (DRG), Diagnosis-Intervention Packet (DIP) and Case Mix Index. ResultsThis study proposed a systematic standard framework for rehabilitation medical records, covering key components such as patient demographics, rehabilitation diagnosis, functional assessment, rehabilitation treatment prescriptions, progress evaluations and discharge summaries. The research analyzed the systematic application methods and data standards of ICD-10/ICD-11, ICF and ICHI Beta-3 in the fields of medical record terminology, coding and assessment. Constructing a standardized data structure and data standards for rehabilitation medical records can significantly improve the quality of data reporting based on the medical record summary sheet, thereby enhancing the quality control of rehabilitation services, effectively supporting the optimization of rehabilitation medical insurance payment mechanisms, and contributing to the establishment of rehabilitation medical performance evaluation and payment based on DRG and DIP. ConclusionStructured rehabilitation records and data standardization are crucial tools for quality control in rehabilitation. Systematically applying the three reference classifications of the WHO-FICs, and aligning with national medical record and electronic health record specifications, facilitate the development of a standardized rehabilitation record architecture and core dataset. Standardizing rehabilitation care pathways based on the ICF methodology, and developing ICF- and ICD-11-based rehabilitation assessment tools, auxiliary diagnostic and therapeutic systems, and supporting terminology and coding systems, can effectively enhance the quality of rehabilitation records and enable interoperability and sharing of rehabilitation data with other medical data, ultimately improving the quality and safety of rehabilitation services.

The nucleus tractus solitarius (NTS) is the primary brain region for receiving and integrating cardiovascular afferent signals. It plays a crucial role in maintaining balance of autonomic nervous system and regulating blood pressure through cardiovascular reflexes. Neurons within the NTS form complex synaptic connections and interact reciprocally with other brain regions. The NTS regulates autonomic nervous system activity and arterial blood pressure through modulating baroreflex, sympathetic nerve activity, renin-angiotensin-aldosterone system, and oxidative stress. Dysfunctions in NTS activity may contribute to hypertension. Understanding the NTS' role in centrally regulating blood pressure and alterations of neurotransmission or signaling pathways in the NTS may provide rationale for new therapeutic strategies of prevention and treatment. This review summarizes the research findings on autonomic nervous system regulation and arterial blood pressure control by NTS, as well as unresolved questions, in order to provide reference for future investigation.

The present study aimed to explore whether hydrogen sulfide (H2S) improved hypoxic pulmonary hypertension (HPH) in rats by inhibiting aerobic glycolysis-pyroptosis. Male Sprague-Dawley (SD) rats were randomly divided into normal group, normal+NaHS group, hypoxia group, and hypoxia+NaHS group, with 6 rats in each group. The control group rats were placed in a normoxic (21% O2) environment and received daily intraperitoneal injections of an equal volume of normal saline. The normal+NaHS group rats were placed in a normoxic environment and intraperitoneally injected with 14 μmol/kg NaHS daily. The hypoxia group rats were placed in a hypoxia chamber, and the oxygen controller inside the chamber maintained the oxygen concentration at 9% to 10% by controlling the N2 flow rate. An equal volume of normal saline was injected intraperitoneally every day. The hypoxia+NaHS group rats were also placed in an hypoxia chamber and intraperitoneally injected with 14 μmol/kg NaHS daily. After the completion of the four-week modeling, the mean pulmonary artery pressure (mPAP) of each group was measured using right heart catheterization technique, and the right ventricular hypertrophy index (RVHI) was weighed and calculated. HE staining was used to observe pathological changes in lung tissue, Masson staining was used to observe fibrosis of lung tissue, and Western blot was used to detect protein expression levels of hexokinase 2 (HK2), pyruvate dehydrogenase (PDH), pyruvate kinase isozyme type M2 (PKM2), nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3), GSDMD-N-terminal domain (GSDMD-N), Caspase-1, interleukin-1β (IL-1β) and IL-18 in lung tissue. ELISA was used to detect contents of IL-1β and IL-18 in lung tissue. The results showed that, compared with the normal control group, there were no significant changes in all indexes in the normal+NaHS group, while the hypoxia group exhibited significantly increased mPAP and RVHI, thickened pulmonary vascular wall, narrowed lumen, increased collagen fibers, up-regulated expression levels of aerobic glycolysis-related proteins (HK2 and PKM2), up-regulated expression levels of pyroptosis-related proteins (NLRP3, GSDMD-N, Caspase-1, IL-1β, and IL-18), and increased contents of IL-1β and IL-18. These changes of the above indexes in the hypoxia group were significantly reversed by NaHS. These results suggest that H2S can improve rat HPH by inhibiting aerobic glycolysis-pyroptosis.

The renin-angiotensin-aldosterone system (RAAS) is crucial for regulating blood pressure and maintaining fluid balance, while clock genes are essential for sustaining biological rhythms and regulating metabolism. There exists a complex interplay between RAAS and clock genes that may significantly contribute to the development of various cardiovascular and metabolic diseases. Although current literature has identified correlations between these two systems, the specific mechanisms of their interaction remain unclear. Moreover, the interaction patterns under different physiological and pathological conditions need further investigation. This review summarizes the synergistic roles of the RAAS and clock genes in cardiovascular diseases, explores their molecular mechanisms and pathophysiological connections, discusses the application of chronotherapy, and highlights potential future research directions, aiming to provide novel insights for the prevention and treatment of related diseases.

ObjectiveTo elucidate the correlation between alterations in digestion and absorption functions and hepatic deficiency states in aging rats based on the R-spondin1/Wnt3a signaling pathway, and reveal the intervention mechanism of Bugansan. MethodsForty-eight SPF-grade male SD rats were randomly assigned to six groups: blank control, model, low-, medium-, and high-dose (7.03, 14.06, 28.12 g·kg-1, respectively) Bugansan, and vitamin E (suspension, 27 mg·kg-1), with 8 rats in each group. The rat model of aging was established by intraperitoneal injection of D-galactose (400 mg·kg-1), while the blank control group was injected with normal saline. Since the day of modeling, rats in intervention groups received corresponding agents by gavage, and those in blank control and model groups received an equal volume of normal saline (10 mL·kg-1). General biological features such as fur color, activity, body mass, water intake, and food intake were observed. Meanwhile, the content of malondialdehyde (MDA) and the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in the serum were measured to assess aging. Grip strength and the content of total bile acids (TBA) and the activity of α-amylase (AMY) in the serum were measured to evaluate hepatic deficiency states. The activity of β-galactosidase (β-gal) in the duodenum was measured to evaluate intestinal senescence. The levels of glucagon-like peptide-1 (GLP-1), vasoactive intestinal peptide (VIP), and D-xylose in the serum were determined to assess digestion and absorption functions of the small intestine. Hematoxylin-eosin staining was conducted to observe pathological changes of the duodenum to assess the small intestine damage. Immunohistochemical staining was employed to visualize the expression of B-cell-specific Moloney murine leukemia virus integration site 1 (Bmi1) and leucine-rich repeat-containing G protein-coupled receptor 5 (Lgr5) in the duodenal tissue. Moreover, Real-time quantitative polymerase chain reaction (Real-time PCR) was utilized to quantify the mRNA levels of Ki67, Bmi1, and Lgr5 to assess proliferation and regeneration of the small intestine. Additionally, the mRNA levels of R-spondin1, Wnt3a, β-catenin, and glycogen synthase kinase-3β (GSK-3β) and the protein levels of R-spondin1, Wnt3a, β-catenin, and phosphorylated GSK-3β (p-GSK-3β) in the duodenum were determined by Real-time PCR and Western blot, respectively, to analyze the mechanisms of intestinal digestion and absorption dysfunction in aging rats and the regulatory characteristics of Bugansan. ResultsCompared with blank control group, the model group showed decreases in body mass, water intake, food intake, grip strength, activities of SOD, GSH-Px, and AMY in the serum and content of GLP-1, VIP and D-xylose in the serum (P<0.05), increases in the content of MDA and TBA in the serum and β-gal activity in the duodenum (P<0.05), reductions in villus length, villus width, crypt depth, and villi/crypt (V/C) value, down-regulated mRNA and protein levels of Ki67, Lgr5, Bmi1, R-spondin1, Wnt3a, β-catenin, and up-regulated level of GSK-3β, phosphorylation (p)-GSK-3β (P<0.05). Compared with the model group, Bugansan increased the body mass, water intake, food intake, grip strength, and activities of SOD, GSH-Px, and AMY and levels of GLP-1, VIP and D-xylose in the serum (P<0.05), while decreasing the content of MDA and TBA in the serum and β-gal activity in the duodenum (P<0.05). Furthermore, Bugansan increased the villus length, villus width, crypt depth, and V/C value, up-regulated the mRNA and protein levels of Ki67, Lgr5, Bmi1, R-spondin1, Wnt3a, β-catenin, and down-regulated the level of GSK-3β and p-GSK-3β (P<0.05). ConclusionAging rats exhibit obvious impairments in digestion and absorption functions, accompanied by a state of hepatic deficiency. The traditional Chinese medicine approach of tonifying liver Qi effectively ameliorates aging-related changes by modulating the R-spondin1/Wnt3a signaling pathway to mitigate intestinal senescence and enhance digestion and absorption functions, ultimately contributing to the delay of aging.
