Objective:Autoimmune gastritis (AIG) is characterized by the loss of acid-secreting glands, resulting in hypochlorhydria and hypergastrinemia, conditions that significantly increase the risk of developing gastric neuroendocrine tumors (NETs) and gastric adenocarcinoma. In recent years, AIG has garnered increasing attention in both clinical and research settings. However, comprehensive studies on the clinical and endoscopic characteristics of AIG particularly cases complicated by gastric neoplastic lesions remain limited in China. This study aims to comprehensively summarize the clinical and endoscopic features of AIG and its associated gastric neoplastic lesions.Methods:A retrospective analysis was conducted using medical records from patients with AIG diagnosed at Sichuan Provincial People′s Hospital between 2019 and 2024. Data collected included demographic information, medical history, serological test results, imaging findings, and endoscopic observations. The clinical and endoscopic features of AIG patients with gastric NETs or epithelial-derived tumors were compared to those without gastric neoplastic lesions to identify potential risk factors and diagnostic indicators for tumor development in AIG.Results:A total of 72 patients with AIG were included, of whom 62.5% (45/72) were female, with an age range of 30 to 79 years old (mean age: 57±11 years). Parietal cell antibody (PCA) positivity was observed in 93.1% (67/72), intrinsic factor antibody (IFA) positivity in 45.8% (33/72), and Helicobacter pylori ( H. pylori) co-infection in 48.6% (35/72). Endoscopically, 84.7% (61/72) showed prominent corpus-dominant advanced atrophy; 47.2% (34/72) had sticky adherent mucus; and 41.7% (30/72) displayed residual oxyntic mucosa in the gastric body or fundus. Only 23.6% (17/72) had normal antrum mucosa, and just 16.7% (12/72) showed a circular wrinkle-like pattern. Gastric neoplastic lesions were identified in 35 patients (48.6%), including 15 cases (20.8%) with NETs and 20 cases (27.8%) with epithelial-derived tumors (four adenocarcinomas, three adenomas, and 13 cases of intraepithelial neoplasia). No significant differences were found between tumor and non-tumor groups in terms of age, gender, PCA/IFA positivity, gastrin levels, anemia status, folic acid, or serum iron levels. However, patients with NETs had significantly lower vitamin B 12 levels compared to those without tumors (183±111 ng/L vs. 323±159 ng/L, t=2.47, P=0.042). Additionally, AIG patients with NETs were more likely to be H.pylori-negative compared to both the non-tumor group (66.7% vs. 35.1%, χ2=5.26, P=0.072) and the epithelial-derived tumor group (66.7% vs. 30.0%, χ2=5.80, P=0.055). The incidence of reverse atrophy in the epithelial-derived tumor group was significantly lower than that in the non-tumor group (65.0% vs. 91.9%, χ2=6.49, P=0.011) and the NETs group (65.0% vs. 93.3%, χ2=3.90, P=0.048).? Conclusion:In AIG patients with NETs, serum vitamin B 12 levels are significantly reduced, suggesting that vitamin B 12 deficiency may be a key risk factor or clinical indicator for NET development in AIG. Furthermore, NETs are more frequently observed in AIG patients without H.pylori infection, while epithelial-derived tumors are more commonly associated with H.pylori co-infection.

ObjectiveTo improve the response capabilities to disasters and prevent major epidemics， it is of practical use to study the capability evaluation system of the national emergency medical rescue team that combines theoretical training and practical exercises， to enhance the overall quality of the teams. MethodsFirst， a capability assessment system for the national emergency medical rescue team was constructed based on the INSARAG External Classification （IEC） standards of the national emergency medical rescue team. Then， based on the outcome based education （OBE） concept， we conducted innovative research on the curriculum design and exercise programs for team building and member training. Finally， an empirical analysis was conducted on the effectiveness of the evaluation system and training exercises based on the statistical analysis of the comprehensive quality evaluation of the Shanghai national emergency medical rescue team from 2020 to 2023， as well as the empirical analysis of the rescue exercise on the Cruise of spectrum. ResultsBased on the linear regression analysis of each core competency indicators， the five core competencies in the evaluation system， including rescue skills， medical and health knowledge， disaster coping ability， team cooperation ability， and mental resilience training， were positively correlated with the cumulative number of trainings （r=0.71， r=0.76， r=0.81， r=0.84， r=0.96，all P<0.05）， indicating that the training was effective and the course design was reasonable. Empirical cases showed that the three-dimensional rescue drill model had remarkable results in the actual combat application and ability improvement of team members. ConclusionThe training courses and drills designed based on the three-level assessment system are effective in improving the comprehensive capabilities of the national emergency medical rescue team.

Objective:To investigate the association between the local renin-angiotensin system (RAS) in human follicular fluid (hFF) and age, ovarian function, in vitro fertilization (IVF) laboratory outcome. Methods:A non-intervention observational study was designed. hFF and medical case history without personal identity of patients who received IVF simply because of male factor infertility in Reproductive Medicine Center, the First Affiliated Hospital of Soochow University during January 2021 and February 2022 were collected. The renin, angiotensin converting enzyme (ACE), ACE2, angiotensin (Ang)Ⅱ and Ang 1-7 levels were detected by enzyme-linked immunosorbent assay kit. The correlation between age and RAS in hFF was analyzed by simple linear regression, and multivariate linear regression was used to further analyze the correlation between the RAS and IVF laboratory outcome.Results:1) A total of 139 samples of analysable hFF were obtained. 2) There was a linear negative correlation between age and renin (Pearson's r=-0.313 3, P<0.001), angiotensin converting enzyme (ACE; Pearson's r=-0.183 6, P=0.031), angiotensinⅡ (AngⅡ; Pearson's r=-0.218 6, P=0.010), ACE/ACE2 (Pearson's r=-0.319 2, P<0.001), AngⅡ/Ang1-7 (Pearson's r=-0.224 3, P=0.008), while the linear relationship with ACE2 and Ang1-7 was not significant (all P>0.05). 3) Basal follicle-stimulating hormone was positively correlated with age ( β=0.636, P<0.001), ACE2 ( β=0.267, P=0.026) and AngⅡ ( β=0.268, P=0.001), while negatively correlated with ACE ( β=-0.320, P<0.001) and Ang1-7 ( β=-0.217, P=0.014). Basal luteinizing hormone was positively correlated with AngⅡ ( β=0.330, P=0.003), while negative correlated with Ang1-7 ( β=-0.395, P=0.002). Antral follicle count was positively correlated with Ang1-7 ( β=0.153, P=0.049), while negatively correlated with age ( β=-0.869, P<0.001) and ACE2 ( β=-0.082, P=0.004). Basal anti-Müllerian hormone was only negatively correlated with age ( β=-0.349, P<0.001). There was no correlation between RAS and basal estradiol, progesterone, prolactin, testosterone (all P>0.05). 4) Oocyte retrieval count was positively correlated with renin ( β=0.146, P=0.014), AngⅡ ( β=0.113, P=0.034) and Ang1-7 ( β=0.185, P=0.002), while negatively correlated with age ( β=-0.717, P<0.001); MⅡ oocyte maturation rate was positively correlated with AngⅡ ( β=0.207, P=0.019) and Ang1-7 ( β=0.217, P=0.026), while negatively correlated with age ( β=-0.518, P<0.001). There was no correlation between RAS and the rates of two pronuclei embryos, transplantable embryos, high-quality embryos (all P>0.05). Conclusion:The local RAS in ovarian follicles is affected by age and correlated with ovarian function and IVF laboratory outcome.

The rapid development of reproductive medicine has made outstanding contribution to the solution of population problem, but it still cannot satisfy all couples to become "complete parents" at the genetic level. As research progressed of regenerative medicine, it is found that the stem cells have the characteristics of promoting endogenous repair, improving oxidative stress level, regulating immune microenvironment, and so on. Therefore, the transplantation of stem cells is considered to be a new and effective therapy to restore the damaged reproductive function. The mesenchymal stem cells are considered as an ideal source for transplantation therapy because of the characteristics of wide source, easy acquisition and low immunogenicity. Furthermore, it has been proven effective in a large number of scientific and clinical researches in the reproductive field. This paper reviews the basic research progress on all kinds of mesenchymal stem cells in the field of reproductive medicine at home and abroad.

Objective:To explore the effect of hospital-community-family trinity linkage home visiting on quality of life of convalescent patients with traumatic brain injury.Methods:A total of 100 convalescence patients with traumatic brain injury admitted to Shanghai Yangzhi Rehabilitation Hospital from January 2019 to January 2020 were selected as the research objects, and randomly divided into the intervention group ( n=51) and the control group ( n=49) by random number table method. The control group received routine rehabilitation nursing guidance. Patients in the intervention group were treated with hospital-community-family triple linkage family visit for nursing intervention for 10 months. The Medical Outcomes Study 36-Item Short-Form (SF-36), General Self-Efficacy Scale (GSES) and Exercise of Self Care Agency Scale (ESCA) were used to compare the quality of life of 2 groups before intervention, 1, 4, 6, 8 and 10 months after intervention. Results:After 6 months of the intervention, eight dimensions of SF-36 such as physiological function, role-physical, body pain, general health, vitality, social function, role-emotional, and mental health scored 29.61 ± 9.21, 38.73 ± 14.42, 41.96 ± 8.25, 38.63 ± 8.43, 50.10 ± 8.03, 42.40 ± 18.28, 43.14 ± 15.34, 38.31 ± 8.88 in the intervention group, and 35.92 ± 8.02, 52.04 ± 14.29, 50.00 ± 11.90, 47.76 ± 9.08, 56.12 ± 7.66, 56.99 ± 19.40, 55.10 ± 16.03, 44.96 ± 7.73 in the control group. The difference between two groups showed significant difference ( t values were -5.21--3.81, all P<0.05). The GSES scores and ESCA scores after 1,4,6,8,10 months of the intervention showed an distinct advantage in the intervention group than the control group ( t values were -20.99-11.55, all P<0.05). Conclusions:The hospital-community-family trinity linkage home visiting could improve the quality of life, self-efficacy, and self-care ability of patients with traumatic brain injury, and promote their rehabilitation effect when they returned to family and society.

Objective:To investigate the effect of hospital-community-family transitional rehabilitation care model on patients with brain trauma and explore an economic, effective, all-sided rehabilitation approach.Methods:A total of 82 in-patients with brain trauma were recruited from January 2018 to June 2019 in Shanghai Yang Zhi Rehabilitation Hospital (Shanghai Sunshine Rehabilitation Center). The participants were allocated into 2 groups based on randomized digital tables. Forty patients in the observation group received the hospital-community-family transitional rehabilitation care, and forty-two patients in the control group received routine rehabilitation care. All the participants completed assessments with the Fugl-Meyer Assessment Scale (FMA), the Barthel Index for the Activities of Daily Living (BI) and the Hamilton Anxiety Scale (HAMA) before the intervention, at discharge, 1 month, 4 months, 6 months and 10 months after discharge, respectively.Results:Before the intervention, no statistical significance was identified in the total scores of FMA, BI and HAMA between the two groups ( P>0.05). Compared to the control group, the total scores of FMA, BI and HAMA in the observation group were significantly improved at the discharge, 1 month, 4 months, 6 months and 10 months after discharge, respectively ( t values were -13.82 - 10.28, all P<0.05). Significant differences were observed in the level of FMA, BI and HAMA between the two groups across 6 time points ( Ftime×group=20.34, 18.34, 19.55, Ftime=183.24, 184.30, 179.09, Fgroup=28.86, 32.19, 26.63, all P<0.05). Conclusions:The hospital-community-family transitional rehabilitation care model which is based on medical consortium effectively improved traumatic brain-injured patients′motor function, the level of activities of daily living, and patients′anxiety. In addition, the model also improved the quality of medical services.

Objective:To explore the application effects of the Doctor-nurse-therapist integrated Model on the patients with brain injury in the rehabilitation period.Methods:A total of 60 patients with brain injury from January 2016 to October 2017 were selected as the control group underwent interventions based on traditional treatment model involving medical treatment, nursing and rehabilitation, and then 56 patients with brain injury from January 2018 to October 2019 were aselected as the experimental group followed Doctor-Nurse-Therapist integrated model for rehabilitation treatment. All subjects were recruited from inpatients hospitalized in the Forth Department of Neurological Rehabilitation, Shanghai Yangzhi Rehabilitation Hospital (Shanghai Sunshine Rehabilitation Center). The differences of motor function, activities of daily life (ADLs), anxiety and depression scores between the two groups were compared.Results:After 6 weeks of interventions, the scores of motor function were 80.27±18.20 and 67.32±19.71, and ADLs scores were 73.14±19.18 and 64.59±20.33 for the experimental group and the control group, respectively. The differences of the motor function and ADLs scores showed statistical significance between the experimental group and the control group ( t values were 3.491, 2.105, P<0.05). The anxiety and depression scores were 44.68±12.29 and 42.61±17.95 in the experimental group, while 52.25±12.95 and 50.84±18.14 in the control group, respectively. Statistical significance was found according to differences of anxiety and depression scores between the experimental group and the control group ( t values were 2.965,-2.236, P<0.05). Conclusions:Under the integrated model, doctors, nurses and therapists can evaluate, discuss, formulate and implement the flow scheme of the model, which can significantly improve the motor function and daily life ability of patients with brain injury in the rehabilitation period as well as anxiety, depression and the quality of medical services, and reduce the burden of family and society.
