ObjectiveTo compare the protective effects of water extracts from fresh and dried Dendrobium huoshanense on gastric mucosa in chronic atrophic gastritis (CAG). MethodsMale SD rats (n=72) were randomly divided into 9 groups, with 8 rats in each group, which were normal group, model group, Yangwei Shu (4 g·kg-1) group, low-, medium-, and high-dose fresh D. huoshanense (3.5, 7, and 14 g·kg-1) groups, and low-, medium-, and high-dose dried D. huoshanense (0.7, 1.4, 2.8 g·kg-1) groups. The CAG rat model was successfully established by inducing with N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) and other factors for a total of 11 weeks. Then, the rats were intervened with fresh and dried D. huoshanense for 4 weeks. The serum and gastric tissues of the rats were collected. The changes in gastric juice secretion volume and gastric acid pH value in each group were observed. The gastric mucosal injury was observed by naked eyes and hematoxylin-eosin(HE) staining. The gastric mucus secretion level was determined by Alcian blue and periodic acid-Schiff staining(AB-PAS) staining. The expression levels of tight junction proteins Occludin and ZO-1 in gastric tissues were determined by immunofluorescence. The expression levels of serum pepsinogen Ⅰ (PG Ⅰ), pepsinogen Ⅱ (PG Ⅱ), gastrin 17 (G-17), interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) were determined by enzyme-linked immunosorbent assay (ELISA). The expression levels of aquaporin 1 (AQP1), aquaporin 3 (AQP3), and aquaporin 4 (AQP4) in gastric tissues were determined by Western blot. ResultsCompared with the normal group, the model group showed an obviously reduced gastric juice secretion volume (P0.05), significantly increased gastric acid pH value (P0.01), gastric mucosa with obvious atrophy, and a significantly reduced gastric mucus secretion volume (P0.01). The expression of Occludin and ZO-1 in the gastric mucosal barrier was significantly decreased (P0.01). The levels of PG Ⅰ and PG Ⅱ in the serum were obviously decreased (P0.05, P0.01), and the levels of G-17, IL-1β, IL-6, and TNF-α were significantly increased (P0.01). The expression level of AQP1 in the gastric tissue was significantly upregulated (P0.01), and the expression levels of AQP3 and AQP4 were significantly downregulated (P0.01). Compared with the model group, each drug administration group could improve the gastric mucosal atrophy of CAG model rats to varying degrees, obviously increase the gastric juice secretion volume of the model rats (P0.05, P0.01), significantly decrease the gastric acid pH value (P0.01), obviously increase the gastric mucus secretion volume (P0.05, P0.01), obviously decrease the expression levels of G-17, IL-6, IL-1β, and TNF-α (P0.05, P0.01), obviously increase the expression levels of Occludin, ZO-1, PG Ⅰ, and PG Ⅱ (P0.05, P0.01), obviously upregulate the expression levels of AQP3 and AQP4 (P0.05, P0.01), and obviously downregulate the expression level of AQP1 (P0.05, P0.01). ConclusionThe water extracts of fresh and dried D. huoshanense can exert therapeutic effects on CAG by improving gastric mucosal injury, reducing inflammation, and regulating water metabolism. Moreover, the dried D. huoshanense has a better effect.

Methods:
Data of newly reported HIV/AIDS cases aged 15 years and older in Shangcheng District from 2006 to 2022 were collected through HIV/AIDS Comprehensive Control System of Chinese Disease Prevention and Control Information System. Population distribution and transmission routes were analyzed, and changing trends in case number were analyzed using average annual percent change (AAPC) and annual percent change (APC).
Results:
A total of 4 409 HIV/AIDS cases aged 15 years and older were newly reported in Shangcheng District from 2006 to 2022, including 3 932 males (89.18%). There were 3 447 cases (78.18%) under 50 years old and 962 cases (21.82%) being 50 years and older. Sexual contact was a predominant transmission route, with 4 326 cases accounting for 98.12%, including 2 626 cases (59.56%) with homosexual contact and 1 700 cases (38.56%) with heterosexual contact. The number of HIV/AIDS cases showed an overall upward trend from 2006 to 2022 (AAPC=13.038%, P<0.05), with an upward trend from 2006 to 2015 (APC=42.578%, P<0.05) and a downward trend from 2015 to 2022 (APC=-19.713%, P<0.05). The increase in the number of cases aged 50 years and older group was faster than that of cases aged under 50 years (AAPC=22.641% vs. 11.162%, both P<0.05). The increase in the number of cases with homosexual contact transmission was faster than that of cases with heterosexual contact transmission (AAPC=20.417% vs. 7.455%, both P<0.05).
Conclusions
The number of newly reported HIV/AIDS cases aged 15 years and older in Shangcheng District performed an overall upward trend from 2006 to 2022. The cases aged 50 years and older and transmitted through homosexual contact increased rapidly, which should be taken seriously.

Objective Recent studies have indicated potential anti-inflammatory effects of glucagon-like peptide-1 receptor agonists(GLP-1RAs)on asthma,which is often comorbid with type 2 diabetes mellitus(T2DM)and obesity.Therefore,we conducted a meta-analysis to assess the association between the administration of glucagon-like peptide-1(GLP-1)receptor-based agonists and the incidence of asthma in patients with T2DM and/or obesity. Methods PubMed,Web of Science,Embase,the Cochrane Central Register of Controlled Trials,and Clinicaltrial.gov were systematically searched from inception to July 2023.Randomized controlled trials(RCTs)of GLP-1 receptor-based agonists(GLP-1RA,GLP-1 based dual and triple receptor agonist)with reports of asthma events were included.Outcomes were computed as risk ratios(RR)using a fixed-effects model. Results Overall,39 RCTs with a total of 85,755 participants were included.Compared to non-GLP-1 receptor-based agonist users,a trend of reduced risk of asthma was observed in patients with T2DM or obesity using GLP-1 receptor-based agonist treatments,although the difference was not statistically significant[RR=0.91,95%confidence interval(CI):0.68 to 1.24].Further Subgroup analyses indicated that the use of light-molecular-weight GLP-1RAs might be associated with a reduced the risk of asthma when compared with non-users(RR=0.65,95%CI:0.43 to 0.99,P=0.043).We also performed sensitivity analyses for participant characteristics,study design,drug structure,duration of action,and drug subtypes.However,no significant associations were observed. Conclusion Compared with non-users,a modest reduction in the incidence of asthma was observed in patients with T2DM or obesity using GLP-1 receptor-based agonist treatments.Further investigations are warranted to assess the association between GLP-1 receptor-based agonists and the risk of asthma.

Objective:To analyze the incidence and prognosis of epilepsy in frontotemporal lobe glioma.Methods:The clinical data of 208 patients with frontotemporal lobe gliomas in Sanbo Brain Hospital Capital Medical University from 2019 to 2021 were analyzed retrospectively. According to the 2016 World Health Organization (WHO) classification of tumors of the central nervous system, the incidence of epilepsy, Modified Rankin Scale (MRS) score, and Engel Outcome Scale of patients with different grades of tumors were calculated.Results:Among all the patients with frontotemporal lobe gliomas, there was more males than females, and it was more common in the 40 -59 age group. The incidence of epilepsy associated with WHO grade Ⅰand Ⅱ glioma was 100.0% (33/33) and 60.9% (14/23), respectively, while that of WHO grade Ⅳ glioma was 19.0%(19/100). The average follow-up time was (22 ± 9) months. During the follow-up period, the incidence of WHO grade Ⅰ, Ⅱ and Ⅲ glioma-related epilepsy decreased significantly. There was no significant difference in the incidence of glioma-related epilepsy between the total and subtotal resection groups ( P>0.05). There was no statistical correlation between the side of tumor occurrence and the occurrence of epilepsy ( P>0.05), also between the gene phenotype and the occurrence of epilepsy ( P>0.05). There was no significant difference in the Engel Outcome Scale among different grades of gliomas ( P>0.05). The prognosis of patients with Engel Outcome Scale Class 1 was significantly better than that of other grades. Conclusions:The incidence of glioma-related epilepsy is negatively correlated with tumor grade. Age and sex are risk factors for glioma-related epilepsy. The incidence of postoperative epilepsy in patients with low grade glioma is significantly lower than that in patients with high grade glioma, and the prognosis is better. However, there is no significant difference in the Engel Outcome Scale among different grades of gliomas.

Based on the current laws and regulations framework of China, combined with practical cases, this paper systematically and comprehensively analyzes the supervision attributes, clinical trial supervision model and existing problems of tumor neoantigen vaccine, aiming to provide reference for the construction of the supervision system of clinical trial of tumor neoantigen vaccine in China. The results showed that, at present, the clinical trials of tumor neoantigen vaccine in China adopt a dual-track supervision model: clinical trials initiated by pharmaceutical enterprises and clinical trials initiated by researchers. This supervision model lags behind the development speed of the industry, mainly in the following aspects: challenges brought by dual- track supervision; the clinical trial data initiated by researchers are not effectively connected with new drug research applications; the guiding principles of clinical trial supervision need to be improved. Relevant medical institutions, regulatory authorities and cooperative enterprises can help the development of the regulatory system for clinical trials of tumor neoantigen vaccine in China from the above aspects.

Objective:To investigate the clinical characteristics and prognosis of acute myeloid leukemia (AML) patients with positive TLS-ERG fusion gene.Methods:The clinical data of 9 AML patients with positive TLS-ERG fusion gene in the First Hospital of Jilin University from June 2013 to August 2020 were retrospectively analyzed, and the relevant literature was reviewed.Results:Among 9 patients with positive TLS-ERG fusion gene, there were 5 males and 4 females, with a median age of 16 years old (6-40 years old). Five patients received chemotherapy alone, 3 patients received allogeneic hematopoietic stem cell transplantation (allo-HSCT), and 1 patient did not receive systematic treatment. Among 8 patients with systematic treatment, 1 patient had complete remission after the first induction chemotherapy and 5 patients had complete remission after induction therapy. The median overall survival time of 5 patients with chemotherapy alone was 1.5 months (1-11 months), of which 3 patients did not respond to the first course of treatment and died of infection, and 2 patients died after relapse. The median overall survival time of 3 patients with allo-HSCT was 16 months (13-17 months), of which 2 patients died after relapse and 1 patient had sustained molecular complete remission by the end of follow-up.Conclusions:AML with positive TLS-ERG fusion gene has low incidence rate and poor induction efficacy. Hematopoietic stem cell transplantation may partially improve the survival prognosis of patients, but it cannot overcome the adverse effect of positive TLS-ERG fusion gene on prognosis.
