OBJECTIVE To analyze the safety and efficacy of vonoprazan （VPZ） in the treatment of peptic ulcer （PU） and post-endoscopic submucosal dissection （ESD） ulcers， providing evidence-based pharmaceutical evidence for clinical practice and medical decision-making. METHODS Retrieved from CNKI， Wanfang， VIP， CBM， PubMed， Embase， Web of Science， and the Cochrane Library， meta-analyses/systematic reviews related to VPZ in the treatment of PU and post-ESD ulcers were collected. Two researchers independently performed literature screening， data extraction， quality assessment of included studies， and evaluation of literature overlap. By employing the umbrella review analysis， a fresh meta-analysis was conducted on all relevant raw research data when a high degree of overlap was identified among the included studies. RESULTS A total of 17 meta-analyses were included， with quality ranging from high to very low； all outcome measures involved showed a very high level of overlap in the included meta-analyses （corrected covered area： 22.22%-100%）. In the treatment of post-ESD ulcers， compared to proton pump inhibitor （PPI）， VPZ significantly improved the ulcer healing rate at 4 weeks post-ESD [RR＝1.27， 95%CI （1.03， 1.56）， Z＝2.21， P＝ 0.027] and the ulcer contraction rate post-ESD [MD＝0.08， 95%CI （0.00， 0.16）， Z＝2.09， P＝0.037]， while significantly reducing the ulcer recurrence rate in patients with a history of PU [RR＝0.49， 95%CI （0.32， 0.73）， Z＝3.49， P＝0.001]； the delayed bleeding rate in the VPZ group was significantly lower than that in the lansoprazole subgroup [RR＝0.47， 95%CI （0.25， 0.90）， Z＝2.28， P＝0.02]. In the treatment of PU， the incidence of adverse events with VPZ was significantly higher than that with PPI in the duodenal ulcer subgroup [RR＝1.13， 95%CI （1.02， 1.26）， Z＝2.38， P＝0.017]. CONCLUSIONS For post-ESD ulcers， VPZ demonstrates superior therapeutic efficacy compared to PPI and can reduce ulcer recurrence rates in patients with a history of PU. However， it does not offer advantages in terms of safety for duodenal ulcer treatment.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

Objective:To compare minimally invasive surgery with traditional open surgery, analyze the current application status of health economic evaluations in the treatment of digestive tract cancers, such as esophageal cancer, gastric cancer, and colorectal cancer by minimally invasive surgery and provide evidence for the rational selection of clinical treatment, alleviation of disease-related economic burdens, and rational allocation of healthcare resources.Methods:By using five databases, i.e. China National Knowledge Infrastructure, Wanfang data, Chinese Biomedical Literature Database, PubMed, and Embase, a database was established to retrieve all the papers about health economic studies of minimally invasive surgery for esophageal cancer, gastric cancer, and colorectal cancer published until December 31, 2023. Literature was analyzed by using software NoteExpress 3.8, and data were processed using Excel 2021. The quality of included papers was evaluated using the CHEERS 2022 checklist, and Meta-analysis was conducted by using software Stata 17.0.Results:A total of 10 919 relevant papers were retrieved, and 59 studies were included. Only 14 studies (23.7%) used standard health economic evaluation methods. Meta-analysis results revealed no significant differences in direct medical expenditure and total expenditure between minimally invasive surgery and open surgery. However, the expenditure for minimally invasive surgery exhibited a significant increase [mean difference ( MD)=5 973.12 yuan, P<0.001], while hospital stay and indirect expenditure significantly decreased ( MD: -4.85 days and -733.79 yuan, P<0.001). In China, for gastric cancer, the direct medical expenditure of endoscopic surgery was lower than that of open surgery ( MD=-33 000.00 yuan) with no significant difference ( P<0.001). In colorectal cancer cases, the direct medical and surgical expenditures for laparoscopic surgery were higher than those for open surgery ( MD: 4 277.94 yuan and 4 267.80 yuan, P<0.001), while the indirect and total medical expenditures decreased ( MD: -768.34 yuan and -159.10 yuan). Hospital stays in patients who had minimally invasive surgery for all three types of cancer were shorter than those who had open surgery ( P<0.001). Conclusions:In the treatment of gastrointestinal cancer, compared with open surgery, minimally invasive surgery shows higher expenditure, but has advantages, such as shorter hospital stay and lower indirect expenditure, and there were no significant differences in direct medical and total expenditures between the two approaches. When conducting health economic evaluation, factors such as postoperative complications, hospital stay, and patient's economic status should be considered for their impact on total medical expenditure. It is necessary to pay attention to the application of health economic evaluations in healthcare decision-making.

Objective:To evaluate the efficacy and safety of Janus kinase (JAK) inhibitors in the treatment of acute severe ulcerative colitis (ASUC).Methods:A retrospective cohort study was conducted. Patients with ASUC treated with JAK inhibitors at the First Affiliated Hospital of Air Force Medical University between January 2021 and March 2024 were enrolled. The primary endpoints were clinical response rate at 1 week and colectomy rate at 90 days. The secondary endpoints were clinical response rate and clinical remission rate at 8 weeks, and adverse events rate at 90 days.Results:A total of 15 patients with ASUC (7 men, 8 women; mean age, 42.47±9.92 years) were included. Eight patients were treated with upadacitinib, and 7 with tofacitinib. The clinical response rate at 1 week was 53.3% (8/15), the colectomy rate at 90 days was 20.0% (3/15), the clinical response rate at 8 weeks was 60.0% (9/15), and the clinical remission rate at 8 weeks was 33.3% (5/15). During the 90-day follow-up, only 1 patient (6.7%) treated with tofacitinib experienced a mild leukopenia.Conclusion:JAK inhibitors are effective for ASUC with the high safety.

Aim To observe the interventional effects of Polygala fallax Hemsl.(PFH)on diabetic kidney disease(DKD)rats and the regulatory mechanism of ferroptosis.Methods Thirty-six SD rats were ran-domly divided into the control group,DKD group,fer-rostatin-1(Fer-1)group,PFH-L group,PFH-M group,and PFH-H group,with six rats in each group.Model-ing was induced by a one-time intraperitoneal injection of 35 mg·kg-1 streptozocin(STZ)in combination with high-sugar and high-fat feed.Ferrostatin-1(25μmol·kg-1)was injected intraperitoneally in Fer-1 group.The PFH-L,PFH-M,and PFH-H groups were gavaged with 50,100 and 200 mg·kg-1 of alcoholic extracts of PFH respectively,and the control and DKD groups were gavaged with an equal volume of distilled water once a day for eight weeks.At the end of drug administration,blood glucose,24h-UP,BUN and Scr levels were measured in each group of rats.HE stai-ning and Masson staining were used to observe renal histopathological changes.ELISA was employed to de-termine the levels of total iron,MDA and GSH activity.IHC was used to observe the expression of Nrf2,SLC7A11,and GPX4 in renal tissues.Western blot was used to detect the protein expression of COL1A1,α-SMA,TGF-,FTH-1,TFR-1,Nrf2,SLC7A1 1,GPX4,in renal tissues.RT-qPCR was used to detect the ex-pression levels of Nrf2,SLC7A11,GPX4 mRNA in re-nal tissues.Results Compared with the control group,blood glucose,24h-UP,BUN,Scr increased(P＜0.05);glomerular volume increased,tubular dilata-tion and collagen fiber deposition were obvious;total i-ron,MDA content increased and GSH activity de-creased(P＜0.05);there was increased protein ex-pression of COL1A1,α-SMA,TGF-β,TFR-1 and de-creased protein expression of FTH-1(P＜0.01);there was decreased mRNA and protein expression of Nrf2,SLC7A11,GPX4 in DKD group rats(P＜0.01).Compared with the DKD group,blood glucose,24h-UP,BUN and Scr decreased(P＜0.05);renal tissue le-sions were significantly reduced;total iron and MDA content decreased,and GSH activity increased(P＜0.05);COL1A1,α-SMA,TGF-β,and TFR-1 protein expression decreased and FTH-1 protein expression in-creased(P＜0.05,P＜0.01);Nrf2,SLC7A11,GPX4 mRNA and protein expression increased in Fer-1 and PFH dose groups(P＜0.05,P＜0.01).Conclusions PFH attenuates renal histopathological injury in DKD rats,and the mechanism may be related to the regula-tion of the Nrf2/SLC7A11/GPX4 signaling pathway.

The scaphoid bone is one of the important bone of hand,which is frequently injured and difficult to treat in clinical practice.Therefore,it is very important to deeply study the microstructure and biomechanical characteristics of the scaphoid bone for understanding its injury mechanism and optimizing treatment scheme.Microcomputed tomography(micro-CT)provides high-resolution imaging of bone tissue,while finite element analysis can help to simulate the stress distribution and behavioral patterns of the scaphoid bone under various physiological and pathological states.The high-resolution three-dimensional image of the scaphoid bone obtained by micro-CT technology can be used to construct finite element models of real anatomical structure of the scaphoid bone,thus achieving accurate simulation of the mechanical properties of the scaphoid bone.The fusion of these two advanced technologies provides a new perspective for revealing the structural and functional relationships and injury mechanism of the scaphoid bone.Therefore,this paper reviews the anatomical characteristics of the scaphoid bone and its biomechanical behavior in different states,emphasizing the specific applications and advantages of micro-CT and finite element analysis techniques in the study of the scaphoid bone.By summarizing the research findings in recent years,this paper provides novel scientific basis and methods for the diagnosis,treatment,and prevention of scaphoid bone-related disorders.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To investigate the clinical features, diagnosis and treatment of adult eosinophilic gastroenteritis (EGE).Methods:A retrospective study was conducted to analyze the clinical manifestations, laboratory examinations, endoscopic manifestations, histopathological characteristics, treatment and prognosis of 29 adult patients with EGE admitted to Xijing Hospital from August 2008 to August 2024.Results:Among the 29 adult EGE cases investigated in this study, 17 cases were male and 12 were female. The mean age was (43±19) years old. The main clinical manifestations included abdominal pain (75.9%), diarrhea (58.6%), and weight loss (44.8%). The median absolute value of white blood cells in peripheral blood of the 29 patients was 7.47(6.66,12.47)×10 9/L, and the white blood cell count increased in 11 cases (37.9%). The median absolute value of eosinophil was 0.98 (0.21,4.76)×10 9/L, and the eosinophil counts increased in 18 cases (62.1%). The main endoscopic manifestations were mucosal hyperemia edema, erosion and roughness. The histopathological manifestations were characterized by abnormal infiltration of eosinophils. In addition, the most commonly involved locations were the ileocecal junction and colorectum. The treatment methods included food elimination, anti-secretory, anti-histamine, and corticosteroids. All patients were alleviated after treatment, but some patients relapsed after drug withdrawal. Conclusions:The main clinical manifestations of adult EGE were abdominal pain, diarrhea and weight loss. Some patients had elevated peripheral blood eosinophilia, and the main endoscopic manifestations were mucosal hyperemia and edema, erosion, and roughness. The histopathological manifestations were characterized by abnormal infiltration of eosinophils. Finally, EGE can be relieved by diet and drug therapy, but it is easy to relapse.
