Occupational disease diagnostician (ODD) is the core technology professional who is responsible for occupational disease diagnosis and identification and the main inspection work for occupational medical examination. The implementation of regular assessment management for ODDs is a key component of standardized workforce management, which facilitates dynamic evaluation of professional competence, regulation of medical practice, and assurance of medical safety. Since January 2025, Guangdong Province has implemented regular assessment management for ODDs within its administrative region. The assessment adopts an integrated model consisting of three components including professional competency evaluation, performance appraisal, and professional ethics evaluation, with each assessment cycle lasting three years. ODDs who passed all three components are classified as qualified ODD, whereas those who failed to pass any one of the three components result in an unqualified assessment outcome. In the implementation of ODD regular assessment management, Guangdong Province has emphasized integrating assessment with quality evaluation, strengthening full-cycle supervision of ODDs′ professional conduct, optimizing assessment strategies for special groups of ODDs, and reinforcing the primary management responsibility of medical institutions. Meanwhile, ODDs′ professional competence, service quality, and professional integrity have been continuously promoted by adopting human-computer interactive assessments, information-based assessment management, and "elimination" mechanism.

Background Although hand-arm vibration syndrome has traditionally been reported more frequently in colder northern regions, recent cases in Guangdong Province, a subtropical region in the south, exhibit a certain degree of clustering in terms of industry distribution and company size, and for a period of time, they account for a high proportion of the total number of cases reported nationwide. Objective To describe the occupational exposure profile of hand-transmitted vibration (HTV) in Guangdong Province in 2025 and to compare exposure levels across industries, enterprise sizes, and occupational categories. Methods Data were sourced from the Guangdong Provincial Occupational Health Quality Control Platform, to which occupational health technical service institutions across Guangdong Province submitted relevant reports in 2025. The dataset included employers with documented HTV hazards, measurement results, and the number of exposed workers. Exposure levels were categorized into four grades according to the 4-h energy-equivalent frequency-weighted vibration acceleration: Grade I (<1 m·s⁻²), Grade II (1-2.5 m·s⁻²), Grade III (>2.5-5 m·s⁻²), and Grade IV (>5 m·s⁻²). Results A total of 12468 employers with identifiable HTV exposure were identified through the platform in 2025, of which 11710 (93.92%) were in the manufacturing sector. By enterprise scale, 274 (2.20%) were large, 934 (7.49%) were medium-sized, 8 749 (70.17%) were small, and 2511 (20.14%) were micro-sized enterprises, with small enterprises accounting for the largest proportion. Among 22298 job posts with identified HTV exposure, grinding, assembly, polishing, burnishing, and welding were the most common tasks. The M (P₂₅, P₇₅) 4-h energy-equivalent frequency-weighted acceleration [a(4)] was 2.1 (1.5, 2.7) m·s⁻², with values ranging from 0.1 to 16.2 m·s⁻². Exposure levels were distributed as follows: Grade I, 2835 posts (12.71%); Grade II, 12761 posts, (57.23%); Grade III, 6690 posts, (30.00%); and Grade IV, 12 posts (0.05%), with Grade Ⅱ posts accounting for the largest proportion. Within the manufacturing sector, 21013 exposed job posts were identified, accounting for 94.24% of all exposed posts. Twelve job posts exceeded the occupational exposure limit, of which nine were polishing positions. A total of 115955 workers were exposed to HTV, primarily in manufacturing (110879; 95.62%). Among the exposed workers, 21237, 23454, 65047, and 6217 were employed in large, medium, small, and micro-sized enterprises, respectively. Grinding, assembly, polishing, deburring, and welding were the five most common occupational categories among the exposed workers. The distribution of worker by exposure grade was similar to that of exposed posts: Grade I, 11921 workers (10.28%); Grade II, 65463 workers (56.46%); Grade III, 38447 workers (33.16%); and Grade IV, 124 workers (0.11%). Conclusion In Guangdong Province, HTV exposure is mainly concentrated in the manufacturing sector, particularly in metal product manufacturing, and commonly involves tasks such as grinding, assembly, and polishing. Both exposed enterprises and exposed workers are predominantly concentrated in small enterprises. Grade II exposure accounts for the largest proportion of both exposed job posts and exposed workers, and some workers are at a risk of developing hand-arm vibration syndrome. These findings suggest that targeted occupational management and comprehensive control measures should be strengthened to reduce HTV exposure and prevent hand-arm vibration syndrome.

Objective:To investigate the completion rate of tumor evaluation at initial assessment and after neoadjuvant therapy for mid and low rectal cancer patients in the national multicenter real-world database.Methods:The prospective real-world study was conducted. The clinicopathological data of 1 074 patients who underwent surgical treatment for mid and low rectal cancer in 47 national medical institutions, including Peking Union Medical College Hospital et al, from May 12,2023 to May 11,2024 were collected. Observation indicators: (1) clinical characteristics of patients with mid and low rectal cancer; (2) initial colonoscopy and pathologic evaluation of tumors in patients with mid and low rectal cancer; (3) initial imaging evaluation of patients with mid and low rectal cancer; (4) imaging evaluation after neoadjuvant therapy for patients with mid and low rectal cancer. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M( Q1, Q3). Count data were described as absoluter numbers and/or percentages. Results:(1) Clinical characteristics of patients with mid and low rectal cancer. Of the 1 074 patients, there were 713 males and 361 females, aged 63(56,70)years. The body mass index of 1 074 patients was 24(21,26)kg/m 2.For American Society of Anesthesiologists classification, there were 147 cases of stage Ⅰ, 641 cases of stage Ⅱ, 157 cases of stage Ⅲ, 2 cases of stage Ⅳ, and there were 127 cases missing data. (2) Initial colonoscopy and pathologic evaluation of tumors in patients with mid and low rectal cancer. Of the 1 074 patients, there were 787 cases (73.28%) undergoing complete colonoscopy, and there were only 197 cases (18.34%) undergoing immunohistochemical evaluation of all four mismatch repair proteins. (3) Initial imaging evaluation of patients with mid and low rectal cancer. Of the 1 074 patients, there were 842(78.40%) patients completing magnetic resonance imaging (MRI) or ultrasound evaluation, and there were 914(85.10%) patients completing chest, abdomen, and pelvis enhanced computed tomography (CT) evaluation. In the 149 patients completing rectal ultrasound evaluation, there were 122 cases (81.88%) comple-ting T staging evaluation, and there were 81 cases (54.36%) completing N staging evaluation. In the 808 patients completing rectal MRI evaluation, there were 708 cases (87.62%) completing T staging evaluation, and there were 590 cases (73.02%) completing N staging evaluation. (4) Imaging evalua-tion after neoadjuvant therapy for patients with mid and low rectal cancer. Of the 388 patients with neoadjuvant therapy, there were 332 patients (85.57%) completing MRI or ultrasound evaluation, and there were 327 patients (84.28%) completing chest, abdomen, and pelvis enhanced CT evalua-tion. In the 70 patients completing rectal ultrasound evaluation, there were 65 cases (92.86%) com-pleting T staging evaluation, and there were 49 cases (70.00%) completing N staging evaluation. In the 327 patients completing rectal MRI evaluation, there were 246 cases (75.23%) completing T staging, and there were 228 cases (69.72%) completing N staging evaluation. Conclusion:The com-pletion rate of tumor imaging evaluation at initial assessment and after neoadjuvant therapy for mid and low rectal cancer patients on a national scale is relatively good.

Objective:To compare the prognostic impact of complete mesocolic excision (CME) versus D2 lymphadenectomy in patients with stage III right-sided colon cancer.Methods:A retrospective cohort study was conducted. Clinical data of 263 patients with stage III colon cancer undergoing right hemicolectomy in the Division of Colorectal Surgery, Department of General Surgery, Peking Union Medical College Hospital (January 1, 2016 to August 8, 2023) were included. Of the 263 patients, 152 underwent CME and 111 received D2 dissection. Propensity score matching (PSM) was employed to balance baseline characteristics between the two groups. Continuous variables were compared using the Mann-Whitney U test or Student's t-test; categorical variables were compared using the χ2 test or Fisher exact test. Survival curves were constructed using the Kaplan-Meier method, and the Log-Rank test was used to compare disease-free survival (DFS) and overall survival (OS) between groups. Cox proportional hazards models were utilized to analyze prognostic factors, with subgroup analyses performed.Results:Patients undergoing CME surgery were younger (proportion >75 years: 4.6% vs. 25.2%, P<0.001), had a lower burden of comorbidities (Charlson comorbidity index ≥ 1: 25.0% vs. 36.9%, P=0.045), The rates of open surgery and converted open surgery were lower [0.6% (1/152) vs. 4.5% (5/111) and 0.6% (1/152) vs. 2.7% (3/111), respectively; P=0.040].They also had a higher rate of receiving adjuvant therapy (92.7% vs. 76.0%, P<0.001). In terms of short-term postoperative outcomes, the CME group had a greater number of harvested lymph nodes (median: 30 vs. 25, P<0.001) and less blood loss (median: 20 ml vs. 20 ml, P=0.041). There were no significant differences between the groups in terms of the number of metastatic lymph nodes, operation time, and the incidence of postoperative complications. Survival analysis demonstrated significantly longer DFS in the CME group both before and after PSM. CME was an independent favorable prognostic factor for DFS (pre-PSM: HR=0.53, 95%CI: 0.31-0.91, P=0.022; post-PSM: HR=0.50, 95%CI: 0.26-0.97, P=0.042). No significant difference in OS was detected between the two groups across models. The subgroup analysis based on clinicopathological features revealed DFS benefits associated with CME in patients with tumor deposits (HR=0.41, 95%CI: 0.18-0.94, P=0.035), moderately-to-well-differentiated adenocarcinoma(HR=0.48, 95%CI: 0.26-0.90, P=0.023), proficient mismatch repair tumors (HR=0.55, 95%CI: 0.32-0.94, P=0.030), and pN2 stage disease (HR=0.43, 95%CI: 0.19-0.95, P=0.036). Conclusion:An extended lymph node dissection, as exemplified by CME, may confer a DFS advantage in patients with stage III right-sided colon cancer, especially those exhibiting a substantial burden of lymph node metastases.

Objective:To compare the impact of different treatment strategies on the survival outcomes in rectal cancer patients with poor response to neoadjuvant therapy, and to explore the survival-related influencing factors.Methods:A retrospective cohort study was conducted. Between January 2018 and November 2022, the clinical, pathological, and follow-up data of 106 rectal cancer patients who received neoadjuvant therapy and were evaluated as grade 4 or 5 based on the Magnetic Resonance Tumor Regression Grade (mrTRG) from the rectal cancer database at Peking Union Medical College Hospital were retrospectively collected. Based on the post-neoadjuvant therapy assessment, patients were classified into three groups: the chemotherapy-radiotherapy group (23 patients), the consolidation therapy group (18 patients), and the standard treatment group (65 patients). General condition, pathological findings, selection of neoadjuvant therapy, comorbidities, as well as 3-year expected DMFS and OS were observed in the three groups.Results:All 106 patients were followed up, with a median follow-up time of 28 (21, 38) months. The overall 3-year DMFS rate was 60%, and the 3-year OS rate was 74%. The 3-year DMFS in the standard treatment and consolidation therapy groups were 74% and 72%, respectively; the 3-year OS were 84%, 81%, respectively. The Log-rank test showed that there was no significant difference in the 3-year expected DMFS and OS between the standard treatment group and the consolidation therapy group (both P>0.05), but both groups had better survival outcomes than the chemotherapy-radiotherapy group (10% and 39%, respectively; all P<0.001). Multivariate Cox regression analysis indicated that the chemotherapy-radiotherapy only regimen was an independent risk factor for DMFS (HR=12.425, 95% CI: 4.436–34.594, P<0.001), and the independent risk factors for OS were chemotherapy-radiotherapy only regimen (HR=8.991, 95%CI:2.220–36.403, P=0.002) and age≥65 years (HR=3.495, 95%CI: 1.017–12.009, P=0.047). Stratified analysis showed that chemotherapy-radiotherapy only regimen was the independent risk factors for DMFS and OS in patients with extramural vascular invasion (EMVI) positive ( n=66) and mesorectal fascial invasion (MRF) positive (n=56) (all P<0.05). Whether consolidation therapy was added to the standard neoadjuvant treatment regimen was not an independent factor affecting 3-year expected DMFS or OS in rectal cancer patients with poor response to neoadjuvant therapy. Further comparisons between the standard neoadjuvant treatment and consolidation therapy groups showed no statistically significant differences in spincter-preservation rate or postoperative complication rates (both P>0.05). However, the consolidation therapy group had a longer interval between the end of radiotherapy and surgery [80.1 (50.8, 109.4) days vs. 61.8 (48.8, 74.8) days, P<0.001], and a higher incidence of chemotherapy-related adverse effects ([10/18] vs. 26.2% [17/65], P=0.018). Conclusion:In rectal cancer patients with poor response to neoadjuvant therapy and clear adverse prognostic features before surgery (locally advanced stage, MRF positive or EMVI positive), the addition of short- or long-course chemotherapy-based systemic therapy does not provide short- or long-term survival benefits. Moreover, an extended chemotherapy duration increases the incidence of chemotherapy-related adverse effects.

Objective:To analyze the types and characteristics of post-operative complications in colorectal cancer patients aged over 85 years undergoing laparoscopic surgery, and to summarize peri-operative management strategies.Methods:This was an observational study. Inclusion criteria: pathologically confirmed adenocarcinoma; tumor located in ileocecum, ascending colon, transverse colon, descending colon, sigmoid colon, or rectum; undergoing laparoscopic radical resection for colorectal cancer; complete clinical data. Exclusion criteria included distant metastasis, synchronous resection of multiple primary cancers, simultaneous liver metastasis surgery, and follow-up duration <1 month. A retrospective analysis was conducted on 191 patients of colorectal cancer patients aged over 85 years who underwent laparoscopic radical surgery in the General Surgery Department at Peking Union Medical College Hospital from January 2019 to January 2024. Among 191 patients, 107 patients (56.0%) had colon cancer and 84 (44.0%) rectal cancer. All patients received "home-based prehabilitation" and post-operative "enhanced recovery after surgery" protocols. Patient characteristics, peri-operative complication types, treatments, and outcomes were analyzed.Results:Post-operative complications occurred in 97 patients (50.8%), including 53 colon cancer patients (54.6%) and 44 rectal cancer patients (45.4%). Comorbidities existed in 88 patients (90.7%), with 93 patients (95.9%) classified as ASA II-III pre-operatively and 86 (88.7%) having nutritional risks. Surgical procedures included Dixon procedure (38 patients, 39.2%), right hemicolectomy (33 patients, 34.0%), sigmoidectomy (10 patients, 10.3%), and 17 patients (17.5%) received prophylactic stomas. Complication types comprised non-anastomotic infections (38 patients, 19.9%), intestinal flora disorder (26 patients, 13.6%), anastomotic/wound/stoma-related complications (16 patients, 8.4%), thrombotic/hemorrhagic events (6 patients, 3.1%), and others (11 patients, 5.8%). By Clavien-Dindo classification: Grade I (12 patients, 6.3%), Grade II (69 patients, 36.1%), Grade III (12 patients, 6.3%), and Grade IV (4 patients, 2.1%). Except for 5 patients (2.6%) requiring unplanned re-operation, all complications resolved with conservative treatment. The median duration of post-operative hospitalization was 9.5 days (7–13).Conclusion:Non-anastomotic infections and intestinal flora disorder constitute predominant complications after laparoscopic surgery in colorectal cancer patients aged over 85 years, mostly manageable with conservative treatment. Strengthened peri-operative management incorporating pre-operative prehabilitation and post-operative enhanced recovery after surgery protocols is crucial for patients aged over 85 years.

Objective To explore the protective effects and mechanism of Shenqi Qiangjing granules containing serum on hydrogen peroxide(H2O2)induced oxidative damage and ferroptosis in mouse spermatogonia(GC-1 spg).Methods Thir-ty SPF grade healthy male SD rats were selected and randomly divided into blank group,levocarnitine group,and Shenqi Qiangjing granules group.After 7 days of intragastric administration,drug-containing serum was collected from each group.Using mouse sper-matogonia as a cell model,they were randomly divided into the normal control group,the model control group,blank serum group,levocarnitine containing serum group,and Shenqi Qiangjing granules containing serum group.Except for the normal control group,the other groups used hydrogen peroxide at a concentration of 600 μmol·L-1 to induce injury to mouse spermatogonia for 4 hours,and then established oxidative stress injury models,after 24 hours of medication intervention in each group.The survival rate of cells was detected using CCK-8 method;The levels of intracellular reactive oxygen species(ROS),malondialdehyde(MDA),catalase(CAT),glutathione(GSH),and superoxide dismutase(SOD)were detected by ELISA;The intracellular iron level was detected by iron ion colorimetry;The activities of Caspase-3 and Caspase-9 were detected by colorimetry;The mRNA levels of glu-tathione peroxidase 4(GPX4)and ACSL4 were determined by qRT-PCR.Results Compared with the normal control group,the cell proliferation activity of the model control group decreased significantly,the levels of ROS,MDA and Fe3+were significantly increased,while the activities of CAT,GSH and SOD were significantly decreased in the model control group,however,Caspase-3 and Caspase-9 activities were significantly increased,the results showed significant difference(P＜0.05).Compare with the model control group,Shenqi Qiangjing granules containing serum could significantly increase the cell proliferation activity,decrease the levels of ROS,MDA and Fe3+,increase the activities of CAT,GSH and SOD,and decrease the activities of Caspase-3 and Caspase-9,the results showed significant difference(P＜0.05).The qRT PCR results showed that compared with the model control group,the expression of GPX4 mRNA was upregulated and ACSL4 mRNA was downregulated in blank serum group containing Shenqi Qiangjing granules,and the differences were statistically significant(P＜0.05).Conclusions Shenqi Qiangjing granules have significant protective effects on hydrogen peroxide-induced oxidative stress injury and ferroptosis of spermatogonia in mice.The mechanism may be related to the decrease of Caspase-3 and Caspase-9 activities and the inhibition of oxidative stress injury and ferroptosis.

Objective To analyze the prescription patterns of Professor Chen Bin in treating chronic superficial gastritis(CSG)with data mining methods.Methods Prescription data from effective medical records of outpatients with CSG treated by Professor Chen Bin at the First Affiliated Hospital of Guangzhou University of Chinese Medicine from October of 2022 to April of 2023 were collected.R language,SPSS,and IBM SPSS Modeler were used to perform frequency statistics,association rule analysis,and systematic cluster analysis on the prescription data,and then the medication and prescription patterns of Professor Chen Bin in treating CSG were explored.Results A total of 64 outpatient prescriptions formulated by Professor Chen Bin were included,involving 95 Chinese herbal medicines.The top 10 frequently-used herbs were Glycyrrhizae Radix et Rhizoma Praeparata cum Melle(Zhigancao),Bupleuri Radix(Chaihu),Pinelliae Rhizoma Praeparatum(Fabanxia),Jujubae Fructus(Dazao),Zingiberis Rhizoma(Ganjiang),Codonopsis Radix(Dangshen),Scutellariae Radix(Huangqin),Paederiae Herba(Jishiteng),Citri Reticulatae Pericarpium(Chenpi),and Taraxaci Herba(Pugongying).Most of the herbs were warm,cold,and mild in nature,and were sweet in flavor.And the herbs mainly had the meridian tropism of spleen,stomach,and liver meridians,and had the primary therapeutic effects of strengthening the spleen and replenishing qi,regulating qi,and resolving dampness.Based on the results of association rule analysis,a total of 21 core herb combinations were screened out,and cluster analysis yielded 4 clustered prescriptions.Combining the results of high-frequency herb statistics and cluster analysis and based on the traditional Chinese medicine theory,the core herbs for treating CSG was identified as Zhigancao,Chaihu,Fabanxia,Dazao,Ganjiang,Dangshen,Huangqin,Jishiteng,Chenpi,and Pugongying.Conclusion In treating CSG,Professor Chen Bin adheres to the treatment principle of replenishing qi and regulating the pivot,and the therapeutic methods of regulating qi movement,strengthening the spleen and harmonizing the stomach are applied with Xiaochaihu Decoction as the fundamental prescriptions.His view of treatment by focusing on the spleen and stomach,emphasizing the combination of herbs with cold and warm properties and based on syndrome differentiation will provide a reference for the clinical application of traditional Chinese medicine in treating CSG.
