Background The prevalence of low back pain among workers using vibrating tools in the automobile manufacturing industry is high; however, research on associated risk factors remains limited. Objective To investigate the association between use of vibrating tools and low back pain among automobile manufacturing workers, and to estimate related population attributable risk percentage (PAR%). Methods A cross-sectional survey was conducted using the Chinese Musculoskeletal Disorders Questionnaire among workers with over one year of service in an automobile manufacturing enterprise. Workers were categorized into an exposed group (vibrating tool users) and a control group (non-users) based on their use of vibrating tools during work. The variables showing statistically significant differences between the two groups were selected as covariates for matching by 1∶2 nearest-neighbor propensity score. Chi-square test was used to compare the prevalence of low back pain between the matched exposed and control groups. Log-binomial regression model was employed to calculate the prevalence ratio (PR), and the PAR% of low back pain attributable to vibrating tool use was subsequently determined. Results A total of

ObjectiveThis study aims to investigate the therapeutic effects of Wenweishu granule (WWSG) on functional dyspepsia (FD) with spleen-stomach deficiency cold syndrome in rats by integrating network pharmacology, molecular docking, and animal experiments. MethodsActive components and corresponding targets of WWSG were collected from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and the Bioinformatics Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine (BATMAN-TCM). Disease-related targets for FD with spleen-stomach deficiency cold syndrome were screened using GeneCards and the Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine (TCMIP). Core therapeutic targets were identified via Cytoscape and validated by molecular docking. A rat model of FD with spleen-stomach deficiency cold syndrome was established using vinegar gavage combined with tail-clamping. The rats were randomly divided into a model group, low-, medium-, and high-dose WWSG groups (2.0, 4.0, 8.0 g·kg-1), a domperidone group (3.0 mg·kg-1), a Fuzi Lizhong pillwan (0.8 g·kg-1), and a normal control group (n=10 per group). Drugs were administered once daily by gavage for 14 consecutive days. After treatment, body weight, symptom scores, and gastrointestinal motility indices were recorded. Gastric and duodenal pathologies changes were observed via hematoxylin-eosin (HE) staining. Brain-gut peptides were measured in serum and tissue using enzyme-linked immunosorbent assay (ELISA). Immunohistochemistry and Western blot were performed to assess stem cell factor (SCF) and receptor tyrosine kinase (c-Kit) protein expression in gastric tissues. ResultsA total of 305 drug targets, 1 140 disease targets, and 116 overlapping targets were identified. Cytoscape analysis revealed 104 core targets. Enrichment analysis indicated that the SCF/c-Kit signaling pathway was the key mechanism. Molecular docking confirmed a strong binding affinity between active components of WWSG and SCF/c-Kit proteins (binding energy<-5.1 kcal·mol-1). Compared with the normal group, model rats exhibited slower weight gain (P<0.05), reduced gastric emptying and intestinal propulsion (P<0.01), mild gastric mucosal shedding, duodenal inflammatory cell infiltration, decreased levels of gastrin (GAS), 5-hydroxytryptamine (5-HT), and vasoactive intestinal peptide (VIP) (P<0.05, P<0.01), and elevated somatostatin (SS) expression (P<0.05, P<0.01). WWSG treatment ameliorated weight gain, symptom scores, and low-grade inflammation in gastric/duodenal tissues. High-dose WWSG significantly improved gastric emptying and intestinal propulsion, upregulated GAS, 5-HT, and VIP, and downregulated SS expression in serum and tissues (P<0.05, P<0.01). Immunohistochemistry and Western blot demonstrated that SCF and c-Kit protein expression was decreased in the model group (P<0.05, P<0.01), which was reversed by WWSG intervention (P<0.05). ConclusionWWSG exerts therapeutic effects on FD with spleen-stomach deficiency cold syndrome in rats, potentially by regulating the SCF/c-Kit signaling pathway to enhance gastrointestinal motility.

OBJECTIVE To systematically evaluate the methodological quality of the postoperative chemotherapy guidelines/ consensuses for ovarian epithelial tumor. METHODS A search was conducted across databases including PubMed, Embase, Web of Science, CBM, VIP, Chinese Medical Journal Data, Wanfang Data, and CNKI, as well as the official websites of GIN, NICE, Medlive, AHRQ, CSCO, ASCO, and NCCN. The search period was from the establishment of the databases/websites to March 10, 2025. The quality of the included guidelines/consensus was evaluated by using the AGREE-Ⅱ tool. RESULTS A total of 16 guidelines/consensuses were included. The domain scores of AGREE-Ⅱ evaluation were as follows: scope and purpose of 85.07%, participants of 47.92%, rigor of development of 57.49%, clarity of presentation of 88.02%, applicability of 8.20%, and independence of 53.39%. Among them, 14 were recommended at grade B and 2 were recommended at grade C. The subgroup analysis by different countries/regions and different types of studies showed that the scores for participants, rigor of development, and independence of the guidelines/consensuses in China were significantly lower than foreign countries (P<0.05); the scores for participants and rigor of development of the guidelines were significantly higher than consensuses (P<0.05). The guideline/ consensus recommendation results indicated that grade B guidelines/consensus recommend platinum-based combination chemotherapy as the preferred adjuvant chemotherapy regimen for stage Ⅰ high-grade serous carcinoma patients;platinum-based combination chemotherapy±bevacizumab was recommended as the preferred adjuvant chemotherapy regimen for stage Ⅱ-Ⅳ high- grade serous carcinoma patients and for platinum-sensitive recurrent high-grade serous carcinoma patients; non-platinum single- agent chemotherapy±bevacizumab was recommended as the preferred chemotherapy regimen for platinum-resistant recurrent high- grade serous carcinoma patients. CONCLUSIONS The overall quality of postoperative chemotherapy guidelines/consensuses for ovarian epithelial tumor is not high. The methodological quality of guidelines/consensuses in China is still lagging behind that of foreign countries. The recommendations differ from those in foreign countries. It is recommended to improve the aspects of participants, rigor of development, and independence, to recommend treatment plans based on the different stages of ovarian cancer, and develop guidelines/consensuses that align with China’s national conditions.

Objective To analyze the factors influencing the occupational health literacy (OHL) level among workers in key industries from the perspectives of both individual workers and enterprises. Methods A total of 32 336 front-line workers from 12 key industries in the secondary industry in Guangdong Province were selected as the research subjects by a stratified cluster random sampling method. Their OHL level was investigated using Occupational Health Literacy Questionnaire of National Key Populations, and the influencing factors were analyzed. Results The OHL level of the research subjects was 48.5%. The OHL level of the research subjects in four dimensions from high to low was basic knowledge of occupational health protection, occupational health practice and behavior, legal knowledge of occupational health, and basic skills of occupational health protection (80.7%, 61.2%, 48.3% and 29.5%, respectively). The multivariable logistic regression analysis showed that the OHL level of female workers was lower than that of males (P<0.05). Lower OHL was also associated with older age, lower education level, lower personal monthly income of workers (all P<0.01). The workers with length of service < 3 years and ≥ 20 years had lower OHL level than those with length of service 3-<10 years and 10-<20 years, respectively (all P<0.05). Workers in larger enterprises had higher OHL levels (all P<0.01). The OHL level of workers in the sixth category of industries with occupational injuries had higher occupational injury risks than those in the third and fourth categories (all P<0.05). The OHL levels of workers in state-owned enterprises, private enterprises, foreign-funded enterprises, and other enterprises were higher than that of workers in public institutions (all P<0.05). Conclusion The influencing factors of workers′ OHL in key industries of the secondary industry include individual factors (gender, age, education level, personal monthly income, length of service) and enterprise factors (enterprise size, enterprise nature and industry injury risk category). Female, older workers, those with lower education or income, and those with short length of service represent priority groups for OHL interventions, while small and micro enterprises are priority units for future workplace health promotion intervention.

The pharmaceutical industry faces challenges in quality digitization for complex multi-stage processes, especially in small-sample systems. Here, an intelligent quality prediction and diagnostic (IQPD) framework was developed and applied to Tong Ren Tang's Niuhuang Qingxin Pills, utilizing four years of data collected from four production units, covering the entire process from raw materials to finished products. In this framework, a novel path-enhanced double ensemble quality prediction model (PeDGAT) is proposed, which combines a graph attention network and path information to encode inter-unit long-range and sequential dependencies. Additionally, the double ensemble strategy enhances model stability in small samples. Compared to global traditional models, PeDGAT achieves state-of-the-art results, with an average improvement of 13.18% and 87.67% in prediction accuracy and stability on three indicators. Additionally, a more in-depth diagnostic model leveraging grey correlation analysis and expert knowledge reduces reliance on large samples, offering a panoramic view of attribute relationships across units and improving process transparency. Finally, the IQPD framework integrates into a Human-Cyber-Physical system, enabling faster decision-making and real-time quality adjustments for Tong Ren Tang's Niuhuang Qingxin Pills, a product with annual sales exceeding 100 million CNY. This facilitates the transition from experience-driven to data-driven manufacturing.

Objective:To investigate and compare the clinical outcomes of the arterial pre-occlusion technique(APOT) and the traditional technique in the surgery of locally advanced pancreatic cancer with arterial involvement after conversion therapy.Methods:This is a retrospective cohort study. The clinical data of 145 patients with locally advanced pancreatic cancer with arterial involvement admitted to the Department of Hepato-Biliary-Pancreatic Surgery of the First Hospital Affiliated to Naval Medical University,from January 2020 to December 2022 were retrospectively analyzed. All patients completed neoadjuvant therapy for tumors, and the feasibility of radical surgical treatment was determined by a multidisciplinary collaborative team evaluation before surgery. According to whether the intraoperative artery was pre-occluded, 145 patients were divided into two groups, including 28 cases in the APOT group(16 males, 12 females, aged (59.0±9.4) years), and 117 cases in the routine surgery group(76 males, 41 females, aged (55.1±8.2) years). To ensure comparability of baseline data between the APOT group and the routine surgery group, a 1∶2 match was performed using the propensity score matching method, and the caliper value was 0.006 45. The t-test,the Mann-Whitney U test, χ2 test or Fisher′s exact test were used to compare the data between the two groups,respectively. Results:After matching the propensity score,there were 28 cases in the APOT group and 56 cases in the routine surgery group. There were no significant differences in gender,age,preoperative comorbidities,preoperative body mass index,surgical approaches,chemotherapy regimen,stereotactic body radiation therapy ratio,tumor markers,and type of invaded artery between the two groups (all P>0.05).The arterial occlusion time M(IQR) in the APOT group was 7.0(3.8)minutes(range:3 to 15 minutes),and no ischemic manifestations were observed in the distal target organs that blocked blood vessels after surgery. The operation time was (170.3±57.7)minutes in the APOT group and (235.0±80.2)minutes in the routine surgery group,and the difference was statistically significant ( t=-3.800, P<0.01). The APOT group also experienced less intraoperative blood loss(650(588)ml vs. 800(600)ml; U=1 026.500, P=0.021). No significant differences were found between the groups in combined vein resection and reconstruction,celiac trunk resection,early postoperative complications, readmission rates at 30 days,and postoperative length of stay(all P>0.05). Extra-arterial dissection was performed in all patients,with arterial resection and reconstruction in 3 cases: 2 cases in the APOT group(1 case involving the superior mesenteric artery and 1 case involving the common hepatic artery) and 1 case in the routine group(involving the common hepatic artery). Postoperative abdominal bleeding occurred in 4 cases,with 3 cases in the routine group,1 case in the routine group. The R0 resection rate was 85.7%(24/28) in the APOT group and 80.4%(45/56) in the routine group,without significant differences between the groups( P=0.763). The median overall survival time was 27.6 months for the APOT group and 22.5 months for the routine group,while the median disease-free survival was 11.7 months and 16.8 months,respectively,with no significant differences between the two groups( P=0.532, P=0.927). Conclusion:The arterial pre-occlusion technique can be used for extra-arterial dissection in patients with locally advanced pancreatic cancer involving the arteries,reducing surgery time and intraoperative blood loss.
