Objective:To explore the clinical efficacy of Bulleyaconitine A combined with pregabalin in the treatment of herpes zoster neuralgia (HZN), and its effects on serum neuropeptide, interleukin-17 (IL-17), CXC chemokine ligand 10 (CXCL10), and nuclear factor-κB (NF-κB) levels.Methods:A total of 114 HZN patients admitted to the Second Hospital of Tianjin Medical University from January 2021 to December 2022 were selected and divided into observation group ( n=57) and control group ( n=57) by random number table method. The control group was treated with oral pregabalin capsules, and the observation group was treated with Bulleyaconitine A on the basis of the control group for 4 weeks. The clinical efficacy of the two groups was observed. The Visual Analogue Scale (VAS) score for pain, total score of Pittsburgh Sleep Quality Index (PSQI), total score of The MOS 36 Item Short form Health Survey (SF-36), as well as serum neuropeptide [substance P (SP), neuropeptide Y (NPY), β-endorphin (β-EP)] and IL-17, CXCL10, NF-κB levels were compared between the two groups before and after treatment. The occurrence of adverse reactions in the two groups was recorded. Results:The total effective rate of the observation group [82.46%(47/57)] was significantly higher than that of the control group [64.91%(37/57), P<0.05]. Before treatment, there were no significant differences in VAS score, total PSQI score, and total SF-36 score between the two groups (all P>0.05); after treatment, the VAS score and total PSQI score of both groups were significantly decreased (all P<0.05), the total SF-36 score was significantly increased (all P<0.05), and the above indicators in the observation group were better than those in the control group (all P<0.05). Before treatment, there were no significant differences in serum SP, NPY, and β-EP levels between the two groups (all P>0.05); after treatment, serum SP and NPY levels in both groups were significantly decreased (all P<0.05), serum β-EP levels were significantly increased (all P<0.05), and serum SP and NPY levels in the observation group were lower than those in the control group (all P<0.05), serum β-EP levels were higher than those in the control group ( P<0.05). Before treatment, there were no significant differences in serum IL-17, CXCL10, and NF-κB levels between the two groups (all P>0.05); after treatment, serum IL-17, CXCL10, and NF-κB levels in both groups were significantly decreased (all P<0.05), and serum IL-17, CXCL10, and NF-κB levels in the observation group were lower than those in the control group (all P<0.05). There was no significant difference in the adverse reaction rate between the observation group [7.02%(4/57)] and the control group [12.28%(7/57)] ( P>0.05). Conclusions:Bulleyaconitine A combined with pregabalin has good efficacy and safety in the treatment of HZN, which can effectively reduce the degree of neuropathic pain and improve sleep and quality of life. Its mechanism may be related to further regulating the level of neuropeptide and inhibiting the inflammatory state in the body.

AIM:To observe the effects of Huangqi-Danggui mixture(HQDG)on the pyroptosis of brain tis-sues in rats with middle cerebral artery occlusion/reperfusion(MCAO/R),and to explore the mechanism of neuroprotec-tion provided by HQDG.METHODS:Sixty-four SD rats were randomly divided into 4 groups:sham group,model group,HQDG group,and Xuesaitong(XST)group.The infarct volume of brain tissues was observed by 2,3,5-triphenyl-tetrazolium chloride staining,while hematoxylin-eosin staining was used to observe the pathological changes of brain tis-sues.Immunofluorescence was employed to assess the expression of nucleotide-binding oligomerization domain-like recep-tor protein 3(NLRP3),cleaved caspase-1 and gasdermin D(GSDMD)in the ischemic penumbra of brain tissues.The se-rum levels of interleukin-1β(IL-1β)and IL-18 were measured using ELISA.Western blot was used to detect NLRP3,cleaved caspase-1,apoptosis-associated speck-like protein containing a caspase recruitment domain(ASC),IL-1β and IL-18 in brain tissues.RESULTS:Compared with sham group,the neurological deficit scores of the rats in model group were significantly increased(P<0.01),while those in HQDG and XST groups were significantly reduced compared with model group(P<0.01).The cerebral infarct volume ratio was significantly reduced in HQDG and XST groups compared with model group(P<0.01).The pathological damage of brain tissue in HQDG and XST groups was significantly reduced compared with model group.The positive rates of NLRP3,cleaved caspase-1 and GSDMD in the ischemic penumbra of brain tissues were significantly decreased in HQDG group compared with model group(P<0.01).The expression of pyrop-tosis-related proteins,NLRP3,cleaved caspase-1 and ASC,in the ischemic penumbra of brain tissues was significantly el-evated in model group compared with sham group(P<0.01),and significantly decreased in HQDG group compared with model group(P<0.01).The serum levels of IL-1β and IL-18 were significantly increased in model group compared with sham group(P<0.01),and significantly reduced in HQDG group compared with model group(P<0.01).CONCLU-SION:The HQDG effectively attenuates brain tissue injury in rats with MCAO/R,and its mechanism may be related to the inhibition of neural cell pyroptosis.

Objective To explore the traditional Chinese medicine(TCM)syndrome characteristics of patients with Chikungunya hemorrhagic fever and to provide empirical data to support the application of TCM in diagnosing and treating Chikungunya hemorrhagic fever.Methods A cross-sectional survey was conducted to collect clinical data(sex,age,days since onset,and comorbidity underlying disease conditions)and TCM with four-examination information(symptoms,tongue manifestations,and pulse manifestations)from 255 patients with Chikungunya hemorrhagic fever who visited Lecong Hospital of Shunde,Foshan,the Third People's Hospital of Shunde District of Foshan,Shunde Hospital of Southern Medical University Affiliated Chencun Hospital between July 23 and July 29,2025.Factor and cluster analyses were used to summarize TCM syndrome characteristics and analyze core pathogenesis in conjunction with clinical features.Results Among the 255 patients with Chikungunya hemorrhagic fever,131 were male and 124 were female,with a age of(49.05±17.93)years and a disease duration of(3.26±1.78)days.Among the four types of examination information in TCM,35 items exhibited a frequency exceeding 10%.The most prevalent symptoms were arthralgia(180 patients,70.59%),exanthem(153 patients,60.00%),fatigue(99 patients,38.82%),anhidrosis(98 patients,38.43%),pruritus(96 patients,37.65%),and fever(92 patients,36.08%).Tongue and pulse manifestations were primarily white fur(155 patients,60.78%),pink tongue(111 patients,43.53%),slippery pulse(143 patients,56.08%),and greasy fur(134 patients,52.53%).Patients with disease onset≤3 d had a higher incidence of arthralgia,fatigue,fever,aversion to cold,generalized muscle pain,aversion to wind,insomnia,headache,sweating,low-grade fever,poor appetite,loose stool,hyperhidrosis,and red tongue than those with disease onset≥4 d(P<0.05).Patients with disease onset≥4 d had a higher incidence of pink tongue and thick fur than those with disease onset≤3 d(P<0.05).The syndrome elements in patients with Chikungunya hemorrhagic fever predominantly manifested on the defensive exterior,with involvement of the sinew-bone joints,skin-muscle,and spleen.Pathogenic factors were primarily characterized by external winds,dampness,and heat.Factor and cluster analysis result indicated three TCM pathogenesis progression patterns:imbalance of the defensive exterior with wind-dampness conflict and heat transformation;dampness-heat flowing into muscles and meridians causing joint obstruction and qi blood stasis;and dampness-heat congelation resulting in qi mechanism obstruction,consumption of body fluids,and infiltration of the skin.Conclusion Patients with Chikungunya hemorrhagic fever primarily present with fever,joint pain,and rashes.In TCM,this condition falls under the category of"dampness-warmth"syndrome.Its etiology is attributed to pathogens,with transmission occurring through mosquito bites.The core pathogenesis of TCM is the invasion of the defensive exterior and dampness-toxic heat accumulation.The therapeutic principles focus on clearing heat pathogens,resolving dampness pathogens,dispersing wind pathogens,and promoting the resolution of rashes.

OBJECTIVES: To assess the effectiveness of the comparison between pit and fissure sealants and fluoride varnishes, as well as various types of sealants, in preventing caries on the occlusal surface of children's first permanent molars (FPM). METHODS: Conduct a comprehensive search of literature published between January 1, 1988, and May 30, 2024, in the following databases: China National Knowledge Infrastructure, Web of Science, Cochrane Library, Embase, PubMed, China Science Periodical Database and China Biology Medicine database. Meta-analysis and subgroup analyses were performed on the literature that met the inclusion criteria. RESULTS: A total of 5 618 pieces of literature were retrieved, resulting in the inclusion of 14 in the study. Meta-analysis showed that there was no statistically significant difference in the efficacy between varies pit and fissure sealants compared to fluoride varnishes, and between varies types of sealants in preventing caries on the occlusal surface of children's first permanent molars within 24 months post-surgery (P>0.05). CONCLUSIONS Within 24 months, there was no significant difference in the effectiveness of using resin-based or glass iomomer pit and fissure sealants compared with fluoride varnishes in preventing occlusal caries in FPM in children; within 24 months, there was no significant difference in the effectiveness of using resin-based sealants compared with ART sealants in preventing occlusal caries in FPM in children. ART sealants are recommended over resin-based sealers for children who have no conditions for chair-side manipulation or who are poorly co-operative.

Objective: To investigate the effects of “Three Methods and Three Acupoints” (TMTP) Tuina therapy on spinal microcirculation in sciatic nerve injury (SNI). Methods: Thirty-six Sprague–Dawley rats were randomly assigned to four groups: normal, sham operation, model, and TMTP Tuina. Successful model induction was confirmed by observable hind limb lameness. After 20 sessions, hind limb grip strength and motor nerve conduction velocity (MNCV) were measured at baseline and following the 10th and 20th intervention. CD31 and α-SMA in the ventral horn of SNI model rats were detected using immunofluorescence. Motor neurons in the ventral horn were detected by Nissl staining. PTEN levels in the ventral horn were measured by ELISA, and PI3K, Akt, BDNF, VEGF, and HIF-1α expression was determined by RT-PCR. Spinal cord microcirculation was evaluated by western blotting analysis of the levels of Akt, p-Akt, BDNF, and VEGF. Results: Hind limb grip strength and MNCV significantly improved in the TMTP Tuina group compared to the model group (both P < .001). Morphology of ventral horn motor neurons in the TMTP Tuina group improved compared to the model group, with increased expressions of α-SMA (P = .002) and CD31 (P = .006). Western blot analysis indicated increased expression of VEGF (P = .005), p-Akt (P < .001), and BDNF (P = .008) in the ventral horn following Tuina treatment. RT-PCR analysis revealed increased expression of PI3K, Akt, BDNF, VEGF and HIF-1α (all P < .05). In contrast, expression of PTEN decreased compared to the model group (P < .001). Conclusion TMTP Tuina therapy may restore motor function in rats, enhance ventral horn motor neuron morphology, and promote angiogenesis and vascular smooth muscle proliferation. The mechanism may involve the activation of the PI3K/Akt signaling pathway.

Objective: To investigate the personnel allocation, structure, and mobility situation of the disease prevention and control (CDC) institutions in Jinhua City, Zhejiang Province from 2018 to 2024, so as to provide insights into strengthening the construction of the talent team within CDC institutions. Methods: Basic information of the personnel in the CDC institutions, Jinhua City were collected through the Basic Information Subsystem of the China Disease Control and Prevention Information System. Composition of age, gender, educational background, major, professional title of the in-service and officially employed personnel, as well as the situation of personnel mobility were analyzed using descriptive methods. Results: A total of 10 CDCs were established in Jinhua City by the end of 2024, including 1 municipal CDC and 9 county (city, district) CDCs, with an approved staffing of 672 people and 621 in-service and officially employed staff. Compared with 2018, the approved number of staff positions in the CDC institutions of Jinhua City increased by 21.30% in 2024, and the number of in-service and officially employed staff members increased by 22.73%. From 2018 to 2024, the number of CDC staff per 10 000 permanent residents in the CDC institutions of Jinhua City, the municipal CDC, and the county (city, district) CDCs were 0.764 to 0.932, 0.142 to 0.173, and 0.623 to 0.759, respectively. From 2018 to 2024, the overall male-to-female ratio in both the municipal CDC and the county (city, district) CDCs decreased from 1.04∶1 and 0.84∶1 to 0.95∶1 and 0.75∶1, respectively. In the municipal CDC, the proportion of staff aged 25-<45 years old increased from 57.45% to 69.02%; the proportion of staff with a bachelor's degree or above increased from 79.79% to 93.81%; the proportion of staff majoring in public health increased from 37.23% to 49.56%; the proportions of staff with various professional titles were relatively stable; 51 staff members joined, all of whom had a bachelor's degree or above; 32 staff members left, among whom 24 retired and 6 were admitted to civil service positions or other units. In the county (city, district) CDCs, the proportion of staff aged 22-<35 years old increased from 30.59% to 37.40%; the proportion of staff with a bachelor's degree or above increased from 71.85% to 89.76%; the proportion of staff majoring in public health increased from 46.60% to 54.33%; the proportion of staff with a junior professional title or below increased from 34.47% to 43.50%; 198 staff members joined, and 194 of them had a bachelor's degree or above; 102 staff members left, among whom 67 retired and 28 were admitted to civil service positions or other units. Conclusions From 2018 to 2024, the number of in-service and officially employed staff in Jinhua CDC institutions increased the academic qualifications and professional composition continue to improve. There are still problems with the number of CDC staff per 10 000 permanent residents being lower than the standard for the personnel establishment in Zhejiang CDCs, a lack of high-level talents, and insufficient personnel stability.

Objective　To conduct an epidemiological investigation and analysis on one imported cholera case in Shenzhen in 2024, providing a reference for cholera prevention and control. Methods　A cholera case and 86 close contacts in 2024 were investigated using methods of field epidemiological investigation. Real-time RT-PCR was employed for Vibrio cholerae nucleic acid detection and typing of collected specimens, followed by isolation culture, whole genome sequencing and analysis. Results　One severe cholera case was confirmed in an Indian businessman, who recovered and was discharged after rescue and rehabilitation. The pathogen was identified as the toxigenic strain of Vibrio cholerae O1 serotype Ogawa, and genetic evolution analysis showed that it had a very close genetic relationship with Vibrio cholerae isolated from multiple countries such as Bangladesh and Pakistan. Among the 86 close contacts under medical observation, no abnormalities were found. A total of 75 close contact specimens and 38 environment smear specimens from epidemic sites were collected, all testing negative. Conclusion　This is an imported cholera epidemic originating from India. The sensitivity of medical institutions to monitoring key infectious diseases such as cholera needs to be improved.

Objective: To investigate the value of the Chinese visceral adiposity index (CVAI) in predicting hypertension risk, so as to provide a tool for the early assessment of hypertension risk. Methods: Health examination individuals aged ≥18 years were selected from four medical institutes in Jinhua City, Zhejiang Province in 2022. Data on basic information, lifestyle, disease history, body mass index, waist circumference, blood pressure, and blood biochemical indicators were collected through questionnaire surveys and physical examinations. CVAI was calculated to assess levels of visceral fat accumulation, divided by quartiles into Q1, Q2, Q3, and Q4 groups. The relationship between CVAI and hypertension was analyzed using a multivariable logistic regression model, and their dose-response relationship was examined using a restricted cubic spline model. The value of CVAI in predicting hypertension risk was evaluated using receiver operating characteristic (ROC) curve. Results: A total of 23 791 individuals were enrolled, with a median age of 68.00 (interquartile range, 14.00) years. Among them, 10 178 (42.78%) were males and 13 613 (57.22%) were females. The median CVAI was 111.40 (interquartile range, 48.23). Hypertension was identified in 15 563 cases, with a prevalence of 65.42%. After adjusting for lifestyle, disease history, and blood biochemical indicators, the multivariable logistic regression analysis revealed that hypertension risk in the CVAI Q2, Q3, and Q4 groups were 2.012 (95%CI: 1.865-2.170), 3.059 (95%CI: 2.826-3.311), and 5.099 (95%CI: 4.672-5.565) times that of the Q1 group, respectively. The restricted cubic spline model revealed a non-linear relationship between CVAI and hypertension risk (Pnon linearity<0.05). Hypertension risk increased more rapidly when the CVAI was ≥81.03. The area under the ROC curve for CVAI in predicting hypertension risk was 0.691, with an optimal cutoff value of 106.01, which falls within the Q2 group. Conclusions There was a nonlinear dose-response relationship between CVAI and hypertension. CVAI can predict the risk of hypertension, and 106.01 can serve as an early warning threshold for risk screening.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.
