Functional dyspepsia (FD) is a prioritized disease category where traditional Chinese medicine (TCM) demonstrates distinct therapeutic advantages. The current western medicine treatment for FD is mainly based on proton pump inhibitors and prokinetic agents, with digestive enzymes, probiotics and antidepressants serving as adjuvant medication, yet such therapies still have certain limitations. TCM treatment for FD includes oral administration of Chinese herbal formulas and Chinese patent medicines, as well as external TCM therapies such as acupuncture and moxibustion, acupoint application, hot medicinal compress therapy, rubbing with ointment, medicinal iontophoresis, auricular acupoint therapy and tui na (Chinese medical massage). The combined treatment of FD with integrated TCM and western medicine can significantly improve clinical effectiveness and reduce adverse reactions. The common mechanisms underlying the therapeutic effects of both TCM and western medicine revolve around the core pathological processes of FD, mainly focusing on restoring gastrointestinal motility, regulating the levels of brain-gut peptides, modulating intestinal microecology, and ameliorating inflammatory status. The differential mechanisms lie in the precise targeting feature of western medicine versus the holistic-regulating and multi-target characteristics of TCM, and the two approaches exert a synergistic effect to enhance efficacy. This paper proposes to leverage the advantages of TCM in holistic regulation and the strengths of western medicine in targeted treatment, so as to provide personalized and comprehensive treatment regimens for FD patients.

ObjectiveThe accuracy of Y-chromosome haplogroup assignment is crucial for tracing paternal lineage in male samples. With the advancement of high-throughput sequencing technologies, high-density Y-SNP genotyping from whole-genome or array-based data has become a standard method for determiningY-chromosome haplogroups. This study systematically evaluated the performance of 4 commonly used high-density SNP genotyping systems—namely, the Global Screening Array (GSA), Chinese Genotyping Array (CGA), Affymetrix array, and the 1240K capture panel—for haplogroup assignment. This work provides a reference for data comparison across different systems. MethodsWe extracted genotype data for the 4 Y-SNP panels from 30× whole-genome sequencing (WGS) data of 1 590 male samples from the 1000 Genomes Project. Additionally, GSA array genotype data from 384 relative pairs (spanning 1st- to 12th-degree relationships) from 109 Chinese Han families were collected. Haplogroup assignment was performed using Y-LineageTracker v1.3.0 software. We assessed the concordance and resolution of haplogroup assignments between the four Y-SNP panels and the WGS data. The consistency and resolution of haplogroup assignments were also evaluated for both the 1000 Genomes Project samples and the 109 family samples collected in this study. Furthermore, the impact of varying numbers of Y-SNPs on haplogroup assignment was examined. ResultsThe GSA and CGA panels demonstrated superior resolution and discrimination of haplogroup subclades compared with the other two panels. The haplogroup assignments from the GSA, CGA, and 1240K panels showed high concordance with WGS data, with consistency rates exceeding 88.70%, whereas the Affymetrix platform exhibited a significantly lower consistency rate of 61.89%. Specifically, the GSA and CGA panels consistently demonstrated superior performance compared with the other two panels in the assignment of haplogroups O-M175 and H-L901, achieving complete concordance (100%) for both haplogroups. In contrast, the Affymetrix panel erroneously assigned all individuals belonging to haplogroup O-M175 to haplogroup K2-M526. Furthermore, its accuracy for haplogroup H-L901 was exceedingly low, at merely 1.41%. This poor performance was characterized by the misassignment of 98.59% of H-L901 samples—specifically, 1.41% to J-M304 and a predominant 97.18% to F-M89. For haplogroup R-M207, all four panels exhibited uniformly high levels of consistency, with concordance values exceeding 94.00%. Notably, for haplogroup E-M96, the 1240K and Affymetrix panels outperformed the GSA and CGA panels in terms of concordance, representing the first instance in which these two panels surpassed the latter. Conversely, for haplogroups J-M304, Q-M242, and I-M170, all 4 panels showed relatively elevated misclassification rates, with the Affymetrix array demonstrating the poorest overall performance. None of the four panels showed any discordant haplogroup assignments among the familial relative pairs analyzed. A positive correlation was observed between the number of Y-SNPs (ranging from 1 000 to 10 000) and classification consistency; however, classification consistency plateaued when the number of Y-SNPs exceeded 10 000. Furthermore, a random sampling analysis conducted on the GSA and CGA panels demonstrated that the haplogroup misclassification rate exhibited negligible fluctuation across the Y-SNP range of 500 to 1 000. Conversely, a marked enhancement in classification consistency was observed as the number of markers increased from 1 000 to 5 000, ultimately reaching a plateau within the interval of 5 000 to 8 000 markers. ConclusionThese findings indicate that the GSA and CGA panels provide high resolution and concordance, delivering reliable Y-haplogroup assignment for forensic investigations.

Investigator-initiated clinical trials (IIT) are an important part of scientific and technological activities involving human study participants. Among them, high-quality IIT can be used to support the marketing and registration application of drugs, medical devices, and other products when conditions permit. Currently, there is a huge gap between IIT and industry-initiated clinical trials. The use of unlisted products in IIT has problems, such as lack of regulatory support, insufficient research funding support, the need to improve the ability of clinical research management departments, the weakness of professional clinical research teams, and the difficulty of ethics review to match the demands. The challenges could be addressed by improving regulations and conducting pilot trials on a small scale, guaranteeing adequate research funding, strengthening the construction of clinical research management systems, building professional clinical research teams, ensuring the quality of ethical reviews and strict follow-up reviews, shifting from ethical reviews to a system for protecting research participants, and reinforcing training for researchers. Ethics committees should strictly review key points, such as the risk-benefit ratio, informed consent, research funding, compensation for damages, qualifications and equipment of research team members, and management of conflict of interest.

Objective:To summarize the clinical characteristics, diagnosis and treatment experience of salivary pleomorphic adenoma in children. Methods:Thirty patients with salivary pleomorphic adenomas treated in Beijing Childrens Hospital from January 2008 to December 2022 were retrospectively reviewed, including 11 boys and 19 girls, with the age ranging from 0.3 to 14.4 years(median age 10.4 years). Initial presentation, medical history, imaging workups, surgical approaches, complications, rates of recurrence were evaluated. Results:Major salivary gland lesions were most common(n=24, 80%); 53.3%(16 of 30) arising in the submandibular glands and 26.7%(8 of 30) in the parotid. Minor salivary gland lesions(n=6, 20%) were removed from the palate, tongue, face, trachea, nasopharynx, and upper mediastinumand. Preoperative imaging was reviewed in all patients and consisted of 26 ultrasound exams, 2 computerized tomography(CT) exams, and 15 magnetic resonance imaging(MRI) exams. Fine needle aspiration biopsy was performed in 12 patients. Surgical excision was performed in all patients. Postoperative complications included transient facial paresis(n=3), Pneumonia and pleural effusion(n=1). Average length of follow-up was 36.7 months; confirmed recurrence occurred in one patients. Conclusion:The symptoms of salivary gland pleomorphic adenoma in children are different according to the location of the tumor. The treatment is complete surgical resection, and a small amount of normal tissue around the tumor should be removed to reduce recurrence.

Objective:
To investigate an outbreak of acute gastroenteritis at a vocational and technical school in Shaanxi Province in 2024, ao as to provide the reference for the handling of school outbreaks.
Methods:
The conducted case searches, individual case investigations, and on-site hygienic investigations were established in accordance with the Guidelines on outbreak investigation, prevention and control of Norovirus infection (2015). The potential risk factors were analyzed by case-control study. Anal swab samples from cases and all canteen staff, as well as environmental swab samples were collected to detect common intestinal pathogens. All reserved food samples in canteen were collected to test for common pathogenic bacteria.
Results:
From October 26 to November 5, 2024, a cumulative total of 53 cases were reported, with an attack rate of 1.47%. The main clinical symptoms included vomiting (83.02%), abdominal pain (56.60%), diarrhea (30.19%), and fever (26.42%). The epidemic curve suggested an intermittent common-source outbreak, with no obvious clustering characteristics in terms of the population and spatial distribution of cases. The case-control analysis revealed that having dinner at the rice-with-dishes-on-top stall on the first floor of the canteen on October 28 was a risk factor for illness (OR=11.025, 95%CI: 2.186-55.601). GⅡ norovirus was detected as positive in anal swab samples from 6 cases and 2 asymptomatic infected canteen staff, as well as in 3 environmental swab samples from the rice-with-dishes-on-top stall. The test results for common pathogenic bacteria in the reserved food samples were all negative.
Conclusions
This outbreak was caused by an acute gastroenteritis epidemic induced by GⅡ norovirus infection, with a transmission pattern consistent with an intermittent homologous outbreak. The possible source of infection was asymptomatic infected canteen staff mainly through foodborne trasmission, and having meals at the rice-with-dishes-on-top stall was the primary risk factor for this outbreak.

Objective:To compare the arthroscopic autologous osteochondral transfer (AOT) and arthroscopic subscapularis augmentation (ASA) in the treatment of recurrent anterior shoulder dislocation complicated with scapular glenoid bone injury less than 20%.Methods:A retrospective analysis was conducted of the clinical data of 42 patients who had been treated at Department of Orthopaedics, The Second Hospital of Lanzhou University for recurrent anterior shoulder dislocation complicated with scapular glenoid bone injury less than 20% from January 2022 to January 2023. There were 30 males and 12 females, with an age of (32.2±15.2) years. Altogether 12 left shoulders and 30 right shoulders were affected. The patients were divided into 2 groups according to their surgical methods: an AOT group in which 15 cases were treated with AOT and an ASA group in which 27 cases treated with ASA. The Rowe score, American Shoulder and Elbow Surgeons (ASES) score, visual analogue scale (VAS), and shoulder range of motion were compared between groups at the last follow-up. All the above indexes were compared between pre-surgery and post-surgery in each group. The incidence of complications in the 2 groups was recorded.Results:There were no statistically significant differences in the preoperative general data between the 2 groups, indicating comparability ( P > 0.05). A total of 42 patients were followed up for (17.2±5.9) months after surgery. At the last follow-up, in the ASA group and the AOT group respectively, the Rowe score was (97.0±4.4) points and (98.3±2.4) points, the ASES score (97.9±5.2) points and (99.1±3.7) points, and the VAS score 0 (0, 0) point and 0 (0, 1) point, showing no significant difference between the 2 groups ( P > 0.05). The above items in the 2 groups were significantly improved compared with those before surgery ( P < 0.05). At the last follow-up, in ASA group and AOT group respectively, shoulder abduction was 169.2°±3.0° and 168.3°±3.1°, and flexion 171.9°±4.0° and 173.3°±4.1°, showing no significant difference between the 2 groups ( P > 0.05); the abduction 90° external rotation was 67.3°±3.2° in the AOT group, significantly better than that in the ASA group (64.4°±3.5°) ( P < 0.05). The above items in the 2 groups were significantly improved compared with those before operation ( P < 0.05). Follow-ups revealed no infection or osteoarthritis. After surgery, 1 case of shoulder re-dislocation and 6 cases of shoulder pain occurred in the ASA group, while no cases of shoulder re-dislocation or shoulder pain occurred in the AOT group. There was no significant difference between the 2 groups in the incidence of complications ( P > 0.05). Conclusions:In the treatment of patients with recurrent anterior shoulder dislocation complicated with scapular glenoid bone injury less than 20%, both AOT and ASA can improve shoulder function, but AOT is superior to ASA in 90° external rotation.

Objective:To evaluate the clinical efficacy of endoscopic treatment of superficial non-ampullary duodenal adenoma.Methods:A retrospective analysis was performed on the clinical data and follow-up information of patients diagnosed with superficial duodenal non-ampullary adenomas via preoperative endoscopy and treated endoscopically at Peking University First Hospital between January 2013 and January 2024. The overall en bloc resection rate, complete resection rate of the lesion, perioperative complications, and recurrence rates were evaluated. Patients were categorized into three groups based on their treatment modality: endoscopic mucosal resection (EMR)( n=46), endoscopic submucosal dissection (ESD)( n=16), and modified ESD (ESD with snare, ESD-S)( n=24). Comparative analyses were conducted to evaluate operative time, en bloc resection rate, and complete resection rate among the three groups. Results:Among 86 patients, the overall en bloc and complete resection rates were 87.2% (75/86) and 86.0% (74/86), respectively. No case of delayed bleeding was observed during the perioperative period. Intraoperative perforation occurred in two patients, both of whom improved following conservative management. Delayed perforation was noted in four patients, and three of them were successfully managed with surgical intervention, while one case was resolved after conservative treatment. During the follow-up period, local recurrence was identified in two patients. Following re-treatment with endoscopy and continuous surveillance, no further recurrence was observed. The operative times for the EMR group, ESD-S group, and ESD group were 4 (1-36) minutes, 25 (5-190) minutes, and 46 (5-150) minutes, respectively. Significant differences were observed in operative times among the three groups ( Hc=49.892, P<0.001). The en bloc resection rates for the EMR, ESD-S, and ESD groups were 80.4% (37/46), 91.7% (22/24), and 100.0% (16/16), respectively. The complete resection rates were 80.4% (37/46), 91.7% (22/24), and 93.8% (15/16) for the respective groups. Conclusion:Endoscopic treatment demonstrates favorable efficacy and safety for superficial non-ampullary duodenal adenoma. In addition to traditional EMR and ESD, ESD-S is also an effective procedure for endoscopic treatment of non-ampullary duodenal adenoma.
