OBJECTIVE: To explore the genetic etiology of 46 Chinese pedigrees affected with Hereditary multiple exostoses (HME) and provide genetic counseling and reproductive intervention. METHODS: Whole-exome sequencing and Sanger sequencing were carried out on 87 patients from the 46 pedigrees to analyze the variants of EXT1 and EXT2 genes. Pathogenicity of the variants was assessed based on the guidelines from the American College of Medical Genetics and Genomics and Association for Molecular Pathology (ACMG/AMP). Prenatal diagnosis and preimplantation genetic testing (PGT) were provided for couples with identified pathogenic mutations. This study was approved by the Medical Ethics Committee of the hospital (Ethics No.: LL-SC-SG-2014-010). RESULTS: In total 17 and 22 pathogenic variants were respectively identified in the EXT1 and EXT2 genes, among which 5 EXT1 and 12 EXT2 variants were unreported previously. Three patients with no family history were found to harbor de novo variants of the EXT1 gene. Twenty nine couples had opted for PGT or underwent prenatal diagnosis following natural conception, and 17 healthy babies were born. CONCLUSION This study has clarified the genetic etiology of 45 HME pedigrees and identified 17 novel variants, which has enriched the mutational spectrum of the EXT1 and EXT2 genes. Reproductive intervention through PGT and prenatal diagnosis have prevented the recurrence of HME in these families.

Purpose: Esophagojejunal anastomotic leakage (EJAL) represents a severe postoperative complication following total or proximal gastrectomy. Treatment strategies include conservative management, endoscopic interventions, and surgery; however, comparative data remain limited. This study aimed to compare clinical outcomes of different strategies to identify the optimal approach based on anastomotic defect size. Materials and Methods: This retrospective study reviewed 100 patients diagnosed with EJAL between January 2015 and October 2024. Patients were categorized into four groups:conservative management, endoscopic vacuum-assisted closure (E-VAC), other endoscopic treatments, and surgery. The primary outcomes were leakage duration and length of hospital stay after EJAL diagnosis, whereas the secondary outcome was time to C-reactive protein normalization. Subgroup analyses were performed according to defect size. Results: Among the 100 patients, 76 were male and 24 were female, with a mean age of 65.7 years. Conservative treatment was the most common modality (53%), followed by other endoscopic treatments (19%), E-VAC (14%), and surgery (14%). In patients with a defect size <1 cm, conservative treatment was associated with significantly shorter leakage duration (P=0.035) and earlier resumption of diet (P=0.029) compared with endoscopic treatment.Among those with defects ≥2 cm, E-VAC demonstrated the most favorable median outcomes across all variables; however, statistical significance was not achieved because of the small sample size. Conclusions Conservative treatment appears to be the most effective treatment strategy for EJAL with anastomotic defects <1 cm. For larger defects (≥2 cm), E-VAC may offer clinical benefit, although further studies are needed to confirm its efficacy. These findings highlight the importance of individualized treatment selection based on defect size.

Objective: To evaluate the prognostic impact of radiologic and pathologic features in patients with interstitial lung disease (ILD) other than idiopathic pulmonary fibrosis (IPF), and to identify the factors associated with the development of progressive pulmonary fibrosis (PPF) and survival. Materials and Methods: This study retrospectively enrolled 75 patients diagnosed with ILD other than IPF who underwent surgical lung biopsy between January 2004 and December 2020. Three chest radiologists independently reviewed the CT features and extent of fibrosis on preoperative and follow-up CT scans. Two pathologists reviewed the histopathological features, including the presence of interstitial pneumonia. The time to PPF and overall survival were estimated using the Kaplan-Meier method. The associations of CT and pathological features with PPF and all-cause mortality were examined using standard Cox regression and time-dependent Cox models, respectively. Results: A total of 75 non-IPF ILD patients (mean age ± standard deviations 56.4 ± 13.2 years; range, 40–88 years) were enrolled. The median follow-up duration was 75.3 months (range, 7.8–189.8 months). Traction bronchiectasis on CT (adjusted hazard ratio [HR], 6.40; P = 0.003) and body mass index (adjusted HR per 1-kg/m2 increase, 0.82; P = 0.002) were found to be significantly associated with PPF in multivariable analysis. Radiological progression (adjusted HR, 18.44;P < 0.001), symptomatic progression (adjusted HR, 4.19; P = 0.011), and age (adjusted HR for 1-year increase, 1.12; P < 0.001) were significantly associated with death. Conclusion Traction bronchiectasis on CT was a significant predictor of PPF, while radiologic and symptomatic progression and older age were associated with poorer survival in patients with ILD other than IPF. These findings indicate that careful radiological evaluation and symptom monitoring may help to predict disease progression and outcomes in patients with nonIPF ILD.

ObjectiveTo understand the epidemiological characteristics and post-exposure prophylaxis of rabies exposure cases in Suqian City of Jiangsu Province from 2021 to 2024, providing a reference for optimizing the allocation of health resources and formulating scientific prevention and control measures. MethodsData on individuals exposed to rabies and treated at Suqian’s rabies post-exposure prophylaxis (PEP) clinics from 2021 to 2024 were collected. Descriptive epidemiological methods were used to analyze patient characteristics, exposure classification, animal species responsible for injuries, wound management, and vaccination status. ResultsBetween 2021 and 2024, the number of outpatient visits for rabies PEP clinics in Suqian City totaled 333 450. The median age and the 25th and 75th percentiles of exposed individuals was 23 (9, 47) years. The highest proportion of exposed individuals was recorded in 2023 (27.09%); the majority were female (52.22%), aged 5‒9 years (17.49%), and in other occupations (37.05%). The rabies exposure rate in Suqian City from 2021 to 2024 was 16.75‰. The overall rabies exposure rate showed an upward trend (χtrend2=1 994.80, P<0.001). The exposure rate among males was lower than that among females (χ²=890.43, P<0.001). The highest exposure rate was observed in the 5‒9 age group (χ²=67 063.20, P<0.001). The number of individuals seeking medical care for rabies exposure exhibited a weak bimodal distribution, with the primary peak occurring in August and the secondary peak in January. The primary animal responsible for injuries was the cat (53.70%), and the source of these animals was predominantly domestic pets (88.90%). The proportion of exposed individuals bitten by cats showed an upward trend from 2021 to 2024 (χtrend2=548.44, P<0.001). Grade Ⅲ exposure accounted for the highest proportion (53.53%), and 301 652 cases (90.46%) presented within 24 hours of exposure. The coverage rate of rabies vaccine was 98.18% (13 625/13 877) for those with Grade Ⅰ exposure and 99.95% (319 413/319 573) for those with Grade Ⅱ and Ⅲ exposures; 64 042 individuals received rabies immunoglobulin or anti-rabies serum; 8 360 exposed individuals received tetanus vaccine, with the usage rate of tetanus vaccine among exposed individuals was only 2.51%, though the rate was on the rise (χtrend2=618.26, P<0.001). ConclusionBetween 2021 and 2024, the overall incidence of rabies exposure in Suqian City showed an upward trend, with a higher incidence among women than men. The incidence was particularly high among children and adolescents aged 14 and under, with the majority of injuries caused by cats; most injuries were inflicted by domestic animals. The overall uptake of tetanus vaccines showed an upward trend. Suqian City should step up health education on rabies exposure during January and August each year, with a particular focus on raising awareness of rabies exposure prevention among people aged 14 and under and women. It should also strengthen the management of domestic animals and ensure that they receive regular rabies vaccinations, particularly for pet cats. Preventive measures against tetanus should be strengthened for individuals exposed to rabies. Medical staff at rabies PEP clinics should receive enhanced training on the management of rabies exposures and the completion of information system reports to ensure the standardized operation of these clinics.

Objective To analyze the incidence and influencing factors of workplace violence (WPV) against nurses in tertiary hospitals in Western China, and to conduct a qualitative exploration based on the lived experiences of nurses who have suffered WPV. Methods A total of 1 294 nurses from 21 tertiary hospitals across 12 provinces, autonomous regions, and municipalities in western China were selected as the research subjects using a convenience sampling method. Investigation was performed among the nurses using the Hospital Workplace Violence Questionnaire and the Implementation Status of Hospital Violence Prevention Measures Questionnaire. Additionally, a total of 18 nurses who had experienced WPV were selected for semi-structured qualitative interviews. Results The overall incidence of WPV among the nurses was 47.5%, with incidences of psychological, physical, and sexual violence at 42.0%, 7.3%, and 3.5%, respectively. Binary logistic regression analysis showed that male nurses had a higher risk of experiencing WPV than female nurses (P<0.01); widowed/divorced nurses had a higher risk than unmarried nurses (P<0.05); both head nurses and department head nurses had a higher risk than general nurses (both P<0.01); and nurses with lower trust in hospitals had a higher risk than those with higher trust (P<0.01). Qualitative interviews revealed that WPV often stemmed from the accumulation of patients′ negative emotions during medical care, exacerbated by poor communication and unmet treatment expectations. Nurses tended to adopt avoidance and tolerance strategies when facing conflict, lacking effective coping skills. Following WPV incidents, nurses frequently experienced anxiety and burnout, relying mainly on self-regulation or confiding in colleagues to cope with the impact of WPV. Hospital responses to WPV are largely passive, with insufficient dedicated departments and psychological support mechanisms, indicating a need for improved institutional frameworks. Conclusion WPV among nurses in tertiary hospitals in Western China remains a serious concern. Hospital management should prioritize high-risk groups such as male and widowed/divorced nurses, and strengthen psychological support systems and standardized reporting procedures to mitigate WPV and to enhance nursing quality.

Purpose: This study aimed to define an optimal age cutoff for early-onset gastric cancer (EOGC) and compare its characteristics with those of late-onset gastric cancer (LOGC) using nationwide survey data. Methods: Using data from a nationwide survey, this comprehensive population-based study analyzed data spanning 3 years (2009, 2014, and 2019). The joinpoint analysis and interrupted time series (ITS) methodology were employed to identify age cutoffs for EOGC based on the sex ratio and tumor histology. Clinicopathologic characteristics and surgical outcomes were compared between the EOGC and LOGC groups. Results: The age cutoff for defining EOGC was suggested to be 50 years, supported by joinpoint and ITS analyses. Early gastric cancer was predominantly present in the EOGC and LOGC groups. Patients with EOGC comprised 20.3% of the total study cohort and demonstrated a more advanced disease stage compared to patients with LOGC. However, patients with EOGC underwent more minimally invasive surgeries, experienced shorter hospital stays, and had lower postoperative morbidity and mortality rates. Conclusion This study proposes an age of ≤50 years as a criterion for defining EOGC and highlights its features compared to LOGC. Further research using this criterion should guide tailored treatment strategies and improve outcomes for young patients with gastric cancer.

Purpose: Multidisciplinary treatment (MDT) in gastric cancer is an effective approach for establishing treatment plans.However, the appropriateness of using “ratio of MDT” as an item for evaluating the adequacy of gastric cancer treatment in Korea has not been previously researched. The purpose of this study is to verify whether the “ratio of MDT” is appropriate as an item for gastric cancer adequacy evaluation from the surgeon’s perspective. Methods: This study involved 142 patients who received MDT at our hospital between December 2015 and January 2023.Patients were divided into 2 groups based on the date when gastric cancer adequacy evaluation was implemented; there were 71 patients before and after the evaluation was conducted, respectively. Based on electronic medical records, the initial plan prepared before the MDT clinic and the final plan prepared after the clinic were compared to determine whether the plan was changed. Results: The average age of patients who received MDT before and after the evaluation was 64.8 and 62.2 years, respectively. Overall, 50 and 21 patients were male (70.4%) and female (29.6%), respectively, in both groups. Before the evaluation, 26 patients (36.6%) who received MDT changed their treatment plans after visiting the clinic, and 15 patients (21.1%) who received MDT after the evaluation had their treatment plans modified. Groups who received MDT and changes in treatment plans were significantly correlated (P = 0.042). Conclusion Our findings suggest that including the “ratio of MDT” as an item of gastric cancer adequacy evaluation needs reassessment.

The differences in chemical quality characteristics between Xinjiang Rehmannia glutinosa and R. glutinosa were analyzed to provide a theoretical basis for the introduction and quality control of R. glutinosa. In this study, the high performance liquid chromatography(HPLC) fingerprints of 6 batches of Xinjiang R. glutinosa and 10 batches of R. glutinosa samples were established. The content of iridoid glycosides, phenylethanoid glycosides, monosaccharides, oligosaccharides, and polysaccharides in Xinjiang R. glutinosa and R. glutinosa was determined by high performance liquid chromatography-diode array detection(HPLC-DAD), high performance liquid chromatography-evaporative light scattering detection(HPLC-ELSD), and ultraviolet-visible spectroscopy(UV-Vis). The determination results were analyzed with by chemical pattern recognition and entropy weight TOPSIS method. The results showed that there were 19 common peaks in the HPLC fingerprints of the 16 batches of R. glutinosa, and catalpol, aucubin, rehmannioside D, rehmannioside A, hydroxytyrosol, leonuride, salidroside, cistanoside A, and verbascoside were identified. Hierarchical cluster analysis(HCA) and principal component analysis(PCA) showed that Qinyang R. glutinosa, Mengzhou R. glutinosa, and Xinjiang R. glutinosa were grouped into three different categories, and eight common components causing the chemical quality difference between Xinjiang R. glutinosa and R. glutinosa in Mengzhou and Qinyang of Henan province were screened out by orthogonal partial least squares discriminant analysis(OPLS-DA). The results of content determination showed that there were glucose, sucrose, raffinose, stachyose, polysaccharides, and nine glycosides in Xinjiang R. glutinosa and R. glutinosa samples, and the content of catalpol, rehmannioside A, leonuride, cistanoside A, verbascoside, sucrose, and glucose was significantly different between Xinjiang R. glutinosa and R. glutinosa. The analysis with entropy weight TOPSIS method showed that the comprehensive quality of R. glutinosa in Mengzhou and Qinyang of Henan province was better than that of Xinjiang R. glutinosa. In conclusion, the types of main chemical components of R. glutinosa and Xinjiang R. glutinosa were the same, but their content was different. The chemical quality of R. glutinosa was better than Xinjiang R. glutinosa, and other components in R. glutinosa from two producing areas and their effects need further study.

OBJECTIVE: To investigate the clinical effect and adverse reactions of dapoxetine hydrochloride versus paroxetine in the treatment of primary premature ejaculation by cross-comparison. METHODS: Based on the clinic-visit time, we equally randomized 148 patients with primary premature ejaculation into groups A and B for a cross-comparison test, the former treated with paroxetine at 20 mg once nightly and the latter with dapoxetine hydrochloride at 30 mg on demand, both for 6 successive weeks, during which we observed the therapeutic effects and adverse reactions. Following 4 weeks of drug discontinuance, we administered dapoxetine hydrochloride at 30 mg on demand for group A and paroxetine at 20 mg once nightly for group B, both for another 6 successive weeks, followed by observation and comparison of the therapeutic effects and adverse reactions. RESULTS: There were no statistically significant differences in the initial characteristics of the two groups of patients (P > 0.05). Compared with the baseline, the mean intra-vaginal ejaculation latency time (IELT) was dramatically improved after treatment in both groups A (4.43 min) and B (7.12 min), increased by 3.99% and 6.72%, respectively (P<0.001). The patients treated with paroxetine showed significantly longer IELT than those taking dapoxetine hydrochloride in both groups (P<0.001). Findings of the Premature Ejaculation Profile (PEP) and spouses' conditions indicated significant improvement after treatment in the average scores of the four indicators of PEP, that is, perceived control over ejaculation, ejaculation-related personal distress, satisfaction with sexual intercourse and ejaculation-related interpersonal difficulty, as well as in the overall experience and partner's satisfaction and orgasm frequency. Adverse reactions to medication were found in 20.8% of the cases in group A and 9.7% in group B, but none was serious. Preference survey following drug withdrawal revealed a preference for paroxetine (61.9%) over dapoxetine (26.8%), and that only a few of the patients thought of the two drugs as comparable or both ineffective. CONCLUSION In term of overall effectiveness, paroxetine was superior to dapoxetine in the treatment of primary premature ejaculation. And the patients obviously preferred the former to the latter, which might be partly attributed to the higher price of dapoxetine.
