Objective:To understand the prevalence of herpes zoster and its influencing factors in population in China, and provide reference for the development of herpes zoster prevention strategies.Methods:A survey was conducted in 27 868 study participants in 25 provinces in China from July to September 2024. The prevalence of herpes zoster was calculated, and multivariate logistic regression analysis was conducted to identify influencing factors.Results:The overall prevalence of herpes zoster in population in China was 6.15% (95% CI: 5.87%-6.43%) and the weighted overall prevalence was 5.89% (95% CI: 5.61%-6.17%). The prevalence in women (6.74%, 95% CI: 6.32%-7.15%) was higher than that in men (5.56%, 95% CI: 5.18%-5.94%). The prevalence increased with age, and the prevalence was 1.33% (95% CI: 1.05%-1.62%) in age group 0-17 years and 12.95% (95% CI: 11.77%-14.13%) in age group ≥70 years. The prevalence in urban population (6.95%, 95% CI: 6.54%-7.37%) was higher than that in rural population (5.30%, 95% CI: 4.92%-5.67%). The prevalence varied in people with different educational levels and increased with the increase of educational level. The prevalence had significant differences among people with different income levels. The prevalence of herpes zoster in adults with chronic diseases (11.09%, 95% CI: 10.45%-11.72%) was higher than that in those without chronic diseases (4.60%, 95% CI: 4.24%-4.97%). Multivariate logistic regression analysis showed that the risk for herpes zoster in women was 1.28 (95% CI: 1.15-1.42) times higher that in men. Older age, higher educational level, urban residence, and suffering from chronic diseases were all associated with increased risk for herpes zoster. Conclusions:The prevalence of herpes zoster was high in population in China. In the prevention and treatment of herpes zoster, it is necessary to take targeted protection measures for key populations, such as women, patients with chronic diseases, middle-aged and elderly people.

Objective To compare the effects of preserving and releasing the inferior pulmonary ligament (IPL) during thoracoscopic right upper lobe apical segment resection for non-small cell lung cancer patients, and to explore appropriate management methods for intraoperative IPL. Methods According to the prospective and open principle, the patients with non-small cell lung cancer who underwent thoracoscopic right upper lobe apical segment resection in the Cardiothoracic Surgery Department of Ningbo Second Hospital from January 2020 to November 2022 were selected and divided into two groups: a release group (receiving IPL release during thoracoscopic right upper lobe apical segment resection) and a retention group (receiving the same right upper lobe apical segment resection, but retaining IPL during operation). The clinical data of the two groups were compared. Results A total of 70 patients were included in this study, including 33 males and 37 females, aged 35-76 years. There were 35 patients in the release group with an average age of (57.02±9.25) years; 35 patients in the retention group with an average age of (56.81±9.94) years. The surgical time in the release group was statistically longer than that in the retention group (P=0.017). There was no statistical difference between the two groups in terms of intraoperative bleeding, duration of postoperative air leakage, time to achieve lung recruitment, drainage flow rate of the chest tube, retention time of the chest tube, incidence of postoperative complications, postoperative hospitalization days, or residual cavity rate one month after the surgery (P>0.05). Conclusion Compared to releasing IPL during thoracoscopic right upper lobe apical segment resection, preserving IPL can simplify surgical procedures, shorten surgical time and reduce trauma, and does not increase postoperative adverse effects. This further reflects the concept of minimally invasive surgery and can be applied to clinical practice.

Background Arsenic, cobalt, barium, and other individual metal exposure have been confirmed to be associated with the incidence of kidney stones. However, there are few studies on the association between mixed metal exposure and kidney stones, especially in occupational groups. Objective To investigate the association between mixed metal exposure and kidney stones in an occupational population from a metal smelting plant. Methods A questionnaire survey was conducted to collect sociodemographic characteristics, medical history, and lifestyle information of 1158 mixed metal-exposed workers in a metal smelting plant in Guangdong Province from July 2021 to January 2022. Midstream morning urine samples were collected from the workers, the concentrations of 18 metals including lithium, vanadium, chromium, manganese, cobalt, nickel, copper, zinc, arsenic, selenium, strontium, molybdenum, cadmium, cesium, barium, tungsten, titanium, and lead were measured by inductively coupled plasma mass spectrometry, and the urinary mercury levels were measured by cold atomic absorption spectroscopy. Based on predetermined inclusion criteria, a total of 919 mixed metal-exposed workers were included in the study, including 117 workers in the kidney stone group and 802 workers in the non-kidney stone group. With a detection rate of urinary metals greater than 80% as entry criterion, 16 eligible metals were finally included for further analysis. Parametric or non-parametric methods were used to compare the differences between continuous or categorical variables of the non-kidney stone group and the kidney stone group. Logistic regression models were constructed to explore the association between individual metal exposures and kidney stones. Weighted quantile sum (WQS) regression models were used to evaluate the association between mixed metal exposure and kidney stones, as well as the weights of each metal on kidney stones. Then Bayesian kernel machine regression (BKMR) models were used to explore the overall effect of mixed metal exposure on renal calculi and the potential interactions between metals. Results We found that there were significant differences in sex, age, length of service, and body mass Index (BMI) between the non-kidney stone group and the kidney stone group (P<0.05). The urinary concentrations of molybdenum and barium in the kidney stone group were higher than those in the non-kidney stone group, and the differences were statistically significant (P<0.05). The logistic regression models demonstrated that urinary cobalt, arsenic, molybdenum, and barium were positively correlated with the risk of kidney stones (P_trend<0.05). The WQS regression models showed that the mixed exposure to vanadium, cobalt, arsenic, molybdenum, and barium was positively associated with the risk of kidney stones (P<0.05). Among them, molybdenum, arsenic, and barium accounted for 0.391, 0.337, and 0.154, respectively. The BKMR results revealed a positive association between metal mixture exposure and the risk of kidney stones (P<0.05). When other metals were fixed at the 25th, 50th, or 75th percentile, arsenic, molybdenum, cobalt, and barium exhibited significant positive effects on the risk of kidney stones (P<0.05), while vanadium showed a significant negative effect (P<0.05). The interaction analysis demonstrated interactions between barium and cobalt, as well as between vanadium and cobalt (P<0.05). Conclusion In the occupational population of this smelter, occupational mixed metal exposure could increase the risk of kidney stones, and the main metals are molybdenum, arsenic, barium, and cobalt.

Objective:To investigate the clinical benefit and application value of the Da Vinci robotic surgical system through bilateral axillary areolar approach in cervical lymph node dissection in obese thyroid carcinoma patients.Methods:The clinical data of 117 patients with thyroid cancer admitted to the thyroid and breast surgery Department of the 960th Hospital of the Chinese PLA Joint Logistic Support Force from January 2018 to June 2023 were retrospectively analyzed. There were 55 males and 62 females, aged from 17 to 64 years, with an average age of (36.05±8.77) years. According to body mass index (BMI), patients were divided into normal group (18.5 kg/m 2≤BMI< 24 kg/m 2, n=60) and obese group (BMI≥28 kg/m 2, n=57). Gender, age, BMI, operation time, postoperative drainage fluid volume, tumor diameter, central lymph node dissection and number of metastasis, cervical lymph node dissection and number of metastasis, postoperative hospital stay, postoperative aesthetic satisfaction score and surgical complications of the two groups were analyzed. SPSS 26.0 statistical software was used to analyze the data. Results:All of patients completed the operation successfully, and neither group was transferred to open surgery. The BMI of obese group was higher than that of normal group [(31.35±3.08) kg/m 2vs (22.53±0.82) kg/m 2, t=20.97, P<0.05]. The maximum tumor diameter in the obese group was greater than that in the normal group [(13.81±10.70) mm vs (10.42±5.53) mm, t=2.17, P<0.05]. There were no significant differences in operation time, number of central lymph node dissection and metastasis, number of cervical lymph node dissection and metastasis and postoperative complications between the two groups ( P>0.05). Conclusions:Utilization of the Da Vinci robotic surgical system via the BABA approach demonstrates both safety and feasibility in obese patients with thyroid carcinoma undergoing lateral cervical lymph node dissection. Importantly, this technique does not increase the risk of surgical complications, thus providing a novel alternative for lateral cervical lymph node dissection in obese thyroid carcinoma patients.

Objective:To study the clinical effect of balloon compression closure kyphoplasty in the treatment of fresh single-segment vertebral compression fracture.Methods:A retrospective study was used to analyze the clinical data of 80 patients with osteoporotic vertebral compression fracture (OVCF) admitted to Gansu Provincial Hospital of Traditional Chinese Medicine from June 2019 to June 2021. They were divided into two groups according to the surgical methods: the simple percutaneous kyphoplasty (PKP) group and the percutaneous kyphoplasty compression group, with 40 patients in each group. The PKP group was routinely treated with PKP, and the PKP compression group was treated with balloon compression occlusion technology on the basis of the PKP group. The amount of bone cement injected, the leakage of bone cement, the height of the anterior edge of the injured vertebra, the Cobb angle of kyphosis, the visual analogue score (VAS) and the Oswestry dysfunction index (ODI) were compared between the two groups. The measurement data conforming to the normal distribution were expressed as ( ± s), and the comparison between the two groups was conducted by t-test; The counting data were expressed by n(%) and the comparison between the two groups adopts Chi-square or Fisher exact probability. Results:The amount of bone cement injected and the leakage rate of bone cement in the PKP compression group were significantly higher than those in the simple PKP group ( P<0.05). The height of the anterior edge of the injured vertebra in the two groups was significantly higher than that before the operation on the first day and three months after the operation ( P<0.05). The Cobb angle, VAS score and ODI index of the injured vertebra in the two groups were significantly lower than that before the operation on the first day and three months after the operation ( P<0.05). The height of the anterior edge of the injured vertebra in the PKP compression group was significantly higher than that in the PKP group ( P<0.05). The Cobb angle of kyphosis in the PKP compression group was significantly lower than that in the simple PKP group at 1 day and 3 months after operation ( P<0.05). There was no significant difference in VAS score between PKP compression group and PKP group on 1 day after operation ( P>0.05), and compared with PKP group on 3 months after operation ( P<0.05). There was no significant difference in the ODI index between the PKP compression group and the two groups 1 day and 3 months after PKP ( P>0.05). Conclusion:Balloon compression closure technology can significantly reduce the leakage of bone cement in PKP and increase the amount of bone cement injected, which is beneficial to reduce the pain of vertebral body and improve the function of OVCF patients, and can improve the clinical treatment effect, which is worth promoting.
