Background::The increasing incidence of inflammatory bowel disease (IBD) presents significant medical and societal challenges. A well-designed IBD database is crucial for both epidemiological studies and clinical management. However, inconsistencies between regional databases hinder cross-institutional and international research, especially between Eastern and Western societies.Methods::We developed a new IBD database, the 301 IBD database, integrating the IBD clinical characteristics from the Penn IBD database (USA) and the latest IBD guidelines and consensus and clinical practices of the Chinese PLA General Hospital (PLAGH). We applied this database to analyze clinical data of IBD inpatients at PLAGH from 2008 to 2023.Results::The 301 IBD database contains 490 items in 6 sections including demographic characteristics, personal history, clinical phenotype, disease activity, laboratory tests and examinations, and treatment. Features of the 301 IBD database include inpatient focus, biochemical indicators and opportunistic infection focus, and more about ulcerative colitis (UC)-associated complications. Single-center analysis revealed an increasing hospitalization trend, from 2.35% in 2008 to 3.94% in 2023. We found that the clinical characteristics of our UC inpatients are predominantly male (62.5%), extensive lesions (55.1%), low usage of biologics (4.1%), and a high incidence of UC-CRC (3.0%). The clinical characteristics of CD inpatients included male predominance (68.39%), early onset age (35.43 ± 14.75-year-old), and high rate of surgery (25.81%).Conclusion::The 301 IBD database, integrating Eastern and Western clinical data, provides a valuable tool for IBD clinical research. Future international, multicenter collaborations are expected to further enhance its utility.

Objective:To evaluate the safety and effectiveness of dual-plane breast augmentation via endoscopic assisted axillary approach.Methods:A retrospective analysis was conducted on 215 female patients who underwent dual-plane breast augmentation via endoscopic assisted axillary approach from March 2019 to March 2021 (15 cases at Longhua Maternal and Child Health Hospital and 200 cases at Chongqing Huamei Hospital). The patient′s age was 22-45 (32.32±5.67) years. 42 cases underwent dual-plane breast augmentation via endoscopic assisted axillary approach, by using a combination of blunt and sharp methods to separate the cavity; while 173 cases used sharp methods to separate cavities. The complications related to breast augmentation were evaluated during a follow-up period of 6 to 18 months.Results:None of the 215 patients experienced wound infection, postoperative hematoma formation, or skin burns. The long-term complications included 1 case (0.46%) of grade Ⅰ capsule contracture, 1 case (0.46%) of grade Ⅲ capsule contracture, and 12 cases (5.58%) of nipple areola sensory impairment or reduction. A patient with grade Ⅲ capsule contracture underwent right capsulotomy and replacement of the prosthesis.Conclusions:The endoscope-assisted transaxillary dual-plane breast augmentation surgery has higher safety and satisfactory, worthy of clinical promotion and application.

Objective To evaluate the effect of CT guided permanent 125I seeds implant brachytherapy on early non-small cell lung cancer (NSCLC) that is not suitable for operation.Methods 18 patients with early stage of NSCLC (stage Ⅰ and Ⅱ) were treated with CT guided permanent seeds 125I implantation from December 2002 to December 2006.The prescribed dose (PD)was 110 Gy,the median activity of 125I seed source was 0.7 mCi.The chest CT detection was performed at 1,2,6 months and 1 year after treatment.The tumor size and the clinical effect were compared before and after treatment.Results The minimum PD in target tumor was (107.7±5.3)Gy,D90 was (113±3.7) Gy,and D9o was more than mPD.The chest CT showed that complete relief (CR) was achieved in 7 patients (38.9％),partial relief (PR) was in 9 patients (50％),stable disease (SD) was in 2 patients (11.1％),no progress disease (PD) was found.The effective rate (CR rate + PR rate) was 92.9％ (16 cases),and local control rate was 88.9％ (16 cases) within one year.During the follow-up to December 2011,the 1,3 and 5 years cumulatively survival rate was 94.4 ％ (17 cases),72.2％ (13 cases),66.7％ (12 cases),56.8％ (10 cases) respectively.Median survival time was 58 months.Conclusions CT-guided permanent 125I seeds implant brachtherapy is effective in the treatment of early non-small cell lung cancer that is not suitable for operation.

With the development of bio-technological drugs, drug immunogenicity evaluation has become key factor of clarifying safety and efficacy of these drugs. It has become the focus to establish a stable and reliable evaluation system. Due to the advantages such as continuous real-time monitoring, surface plasmon resonance (SPR) technology has been widely used in bio-technological drugs immunogenicity assessments. Our study applied this technology to detect anti-drug antibody (ADA) of a recombinant human anti-rabies monoclonal antibody NM57 in the sera of 48 volunteers admitted in phase I clinical trials. This method could satisfy the basic requirements of detection of ADA.
