Ginsenoside Rg_2(GRg2) is a triterpenoid compound found in Panax notoginseng. This study explored its effects and mechanisms on diabetic retinopathy and angiogenesis. The study employed endothelial cell models induced by glucose or vascular endothelial growth factor(VEGF), the chorioallantoic membrane(CAM) model, the oxygen-induced retinopathy(OIR) mouse model, and the db/db mouse model to evaluate the therapeutic effects of GRg2 on diabetic retinopathy and angiogenesis. Transwell assays and endothelial tube formation experiments were conducted to assess cell migration and tube formation, while vascular area measurements were applied to detect angiogenesis. The impact of GRg2 on the retinal structure and function of db/db mice was evaluated through retinal thickness and electroretinogram(ERG) analyses. The study investigated the mechanisms of GRg2 by analyzing the activation of Yes-associated protein(YAP) and Toll-like receptors(TLRs) pathways. The results indicated that GRg2 significantly reduced cell migration numbers and tube formation lengths in vitro. In the CAM model, GRg2 exhibited a dose-dependent decrease in the vascular area ratio. In the OIR model, GRg2 notably decreased the avascular and neovascular areas, ameliorating retinal structural disarray. In the db/db mouse model, GRg2 increased the total retinal thickness and enhanced the amplitudes of the a-wave, b-wave, and oscillatory potentials(OPs) in the ERG, improving retinal structural disarray. Transcriptomic analysis revealed that the TLR signaling pathway was significantly down-regulated following YAP knockdown, with PCR results consistent with the transcriptome sequencing findings. Concurrently, GRg2 downregulated the expression of Toll-like receptor 4(TLR4), TNF receptor-associated factor 6(TRAF6), and nuclear factor-kappaB(NF-κB) proteins in high-glucose-induced endothelial cells. Collectively, GRg2 inhibits cell migration and tube formation and significantly reduces angiogenesis in CAM and OIR models, improving retinal structure and function in db/db mice, with its pharmacological mechanism likely involving the down-regulation of YAP expression.

Since the promulgation of the first Drug Administration Law of the People's Republic of China 40 years ago in 1984, China has undergone four main stages in the traditional Chinese medicine(TCM) regulation: the initial establishment of TCM regulation rules(1984-1997), the formation of a modern TCM regulatory system(1998-2014), the reform of the review and approval system for new TCM drugs(2015-2018), and the construction of a scientific regulation system for TCM(2019-2024). Over the past five years, a series of milestone achievements of TCM regulation in China have been achieved in the six aspects, including its strategic objectives and the establishment of a science-based regulatory system, the reform of the review and approval system for new TCM drugs, the optimization and improvement of the TCM standard system and its formation mechanism, comprehensive enhancement of regulatory capabilities for TCM safety, international harmonization of TCM regulation and its role in promoting innovation. Looking ahead, centered on advancing TCMRS to establish a sound regulatory framework tailored to the unique characteristics of TCM, TCM regulation will evolve into new reform patterns, advancing and extending across eight critical fronts, including the legal framework and policy architecture, the review and approval system for new TCM drugs, the quality standard and management system of TCM, the comprehensive quality & safety regulation and traceability system, the research and transformation system for TCMRS, AI-driven innovations in TCM regulation, the coordination between high-quality industrial development and high-level regulation, and the leadership in international cooperation and regulatory harmonization. In this way, a unique path for the development of modern TCM regulation with Chinese characteristics will be pioneered.

Objective To explore the Helicobacter pylori (Hp) infection rate and antibody typing of 1111 physical examination people in plateau area, and to analyze the risk factors of Hp infection by logistics regression analysis. Methods 1111 healthy people with physical examination in plateau area from January 2022 to December 2022 were selected as the research subjects. The Hp infection rate and antibody typing were calculated, and the risk factors of Hp infection were analyzed by logistics regression analysis. Results The Hp infection rate of physical examination people in plateau area was 62.47% (694/1 111). The infection rate of type I HP in infected patients was higher than that of type Ⅱ HP(75.50% vs 24.50%) (χ2=361.141, P<0.001). The AUC of CagA in the diagnosis of Hp infection was higher than that of antibody VacA or Ure positive diagnosis alone (Z=6.740, 7.608, P<0.001). The proportions of people with male gender, often eating pickled or barbecued foods, history of chronic gastric disease and family members living together≥4 in infected group were higher than those in uninfected group (χ2=4.418, 8.708, 16.565, 32.583, P=0.036, 0.003, <0.001, <0.001) while the proportion of people with regular garlic consumption was lower than that in uninfected group (χ2=5.153, P=0.023). Often eating pickled or barbecued foods [OR (95%CI)=2.038 (1.049-3.961)], history of chronic gastric disease [OR(95%CI)=1.706 (1.132-2.569)] and family members living together≥4 [OR (95%CI)=1.857 (1.135-3.037)] were risk factors of Hp infection, and regular garlic consumption [OR (95%CI)=0.559 (0.346-0.903)] was a protective factor (P=0.036, 0.011, 0.014, 0.018). Conclusion The Hp infection rate and antibody Ure positive rate are higher in physical examination people in plateau area, and chronic gastric disease history and often eating pickled or barbecued foods are risk factors of Hp infection.

Protein phosphorylation modification is one of the key regulatory mechanisms in cellular signaling transduction and metabolic processes. The phosphorylation state of target proteins is regulated by specific protein kinases and phosphatases, which add or remove phosphate groups. Histidine phosphorylation (pHis) plays a crucial role in both prokaryotes and eukaryotes life activities and is linked to various pathological processes. Unlike the stable phosphorylation of proteins via phosphate ester bonds, histidine phosphorylation is linked through phosphoramide bonds, making it highly sensitive to high temperatures and low pH. This sensitivity has historically impeded progress in identifying and studying histidine phosphorylation. In recent years, the development of new techniques in phosphoproteomics and the emergence of pHis-specific antibodies have promoted the identification and functional research of pHis-modified substrates. For the first time, more than 700 pHis-modified proteins have been identified in mammalian cells, and pHis-modified substrates such as focal adhesion kinase (FAK) and phosphoglycerate mutase 1 (PGAM1) have been found to promote tumor development. This article mainly reviewed the key mechanisms and functions of histidine kinases and histidine phosphatases in regulating the histidine phosphorylation of specific substrates, and highlights their significant roles in human physiological and pathological processes, aiming to provide guidance for further research into the biological functions of histidine phosphorylation.

ObjectiveTo evaluate the expression level of DNA damage repair gene FANCI in hepatocellular carcinoma (HCC) and its relationship with prognosis, clinical stage and immune infiltration. MethodsIn this study, TCGA, GTEx, TIMER2.0, HPA database and qRT-PCR, western blot and immunohistochemistry were used to analyze the expression of FANCI in HCC and its correlation with different clinical stages; Kaplan-Meier Plotter database was used to explore the relationship between FANCI and the prognosis of HCC; the TISIDB database was used to analyze the relationship between FANCI and immune cell infiltration and immune checkpoints in HCC; the STRING database was used to detect the protein binding with FANCI; the TCGA and GTEx databases were used for GO and KEGG enrichment analysis; Cell experiments were used to explore the role of FANCI in HCC. ResultsCompared with normal tissues, the mRNA and protein expression levels of FANCI in tumor tissues were up-regulated (P<0.001); and HCC patients with high expression of FANCI had poor prognosis (P<0.001); the expression of FANCI in tumor tissues was positively correlated with the number of activated CD4+ T cells, the number of Th2 cells and the expression of immune checkpoints, and B-cell and macrophage infiltration was significantly lower in the FANCI high expression group (P<0.01); GO and KEGG enrichment analysis showed that FANCI-related genes were enriched in various biological processes such as amino acid transmembrane transporter activity; Cell experiments showed that knockdown of FANCI could inhibit the proliferation, invasion and migration of HCC (P<0.05). ConclusionsFANCI is highly expressed in hepatocellular carcinoma tissues, which may play a role in suppressing anti-tumor immunity and acting on pathways such as amino acid transmembrane transport, and is associated with poor prognosis. The proliferation, invasion and migration ability of hepatocellular carcinoma are inhibited after knocking down FANCI.

Objective: To explore the relationship between sleep/physical activity and metabolic syndrome (MS) in urban population of Xinjiang. Methods: This is a prospective, cross-sectional study. From July 2019 to September 2021, a two-stage random sampling method was used to randomly select residents aged 30-74 years from two communities in Urumqi of northern Xinjiang and Korla of southern Xinjiang. General situation questionnaire, Pittsburgh Sleep Quality Index Scale (PSQI) survey, International Physical Activity Questionnaire (IPAQ) survey, physical examination, physiological and biochemical indicators were obtained and analyzed. The dose-response curves of healthy sleep score and physical activity with metabolic syndrome were plotted using restricted cubic spline curves. Multivariate logistic regression model was used to analyze the independent and combined effects of sleep quality and physical activity on MS risk. Results: A total of 10 209 participants were included. The mean age of the subjects was (47.1±9.1) years, and males accounted for 51.3% (5 275/10 209). The prevalence of MS was significantly associated with the healthy sleep score and physical activity. Compared to the subjects with healthy sleep, OR (95%CI) of MS with intermediate, and poor sleep were 1.20(1.06-1.35), 1.23(1.04-1.45), respectively. Compared to the subjects with high physical activity, OR (95%CI) of MS with medium, low physical activity was 1.34(1.15-1.56), 1.42(1.19-1.70), respectively. There was a significant interaction between sleep and physical activity in MS (P for interaction=0.002). Compared to the subjects with high physical activity and healthy sleep, OR (95%CI) of MS with poor sleep and high physical activity was 2.03 (1.24-3.33, P for trend=0.016). Conclusion: Poor sleep quality and lack of physical activity are not only independent risk factors for an increased risk of MS but also have a combined effect with an increased risk of MS.

OBJECTIVE:
To study the effect of propofol used for painless gastroscopy and colonoscopy on psychomotility recovery.
METHODS:
One hundred adult patients undergoing painless gastroscopy and colonoscopy were recruited, aged 18-72 years, with American Society of Anesthesiologist (ASA) physical status Ⅰ-Ⅱ. According to age, the patients were divided into youth group (20-39 years old, 27 cases), middle age group (40-54 years old, 37 cases), and elder group (55-64 years old, 36 cases). Propofol was continuously infused according to the patients' condition to mantain the bispectal index (BIS) score 55-64. All the patients received psychomotility assesment 30 min before the operations when the discharge criteria were met including number cancellation test, number connection test and board test. The heart rate, blood pressure, saturation of pulse oximetry, electrocardiograph and BIS were monitored during the operation. The operating time, recovery time, total volume of propofol and discharge time were recorded. If the results obtained were inferior to those before operation, a third assessment was taken 30 minutes later until the results recovered or being superior to the baseline levels.
RESULTS:
All the patients completed the first and second assessments, and 25 patients had taken the third assessment. There was no statistically significant difference in the results of psychomotility assessment when the patients met the discharge standard. Furthermore, the results were analyzed by grouping with age, and there was no statistical difference in the test results of the youth and middle age groups compared with the preoperative group, among which, the efficiency of the number cancellation test was significantly better than that before operation in the youth group (P < 0.05). However, in the elderly patients the number cancellation efficiency, number connection test and board test were significantly inferior to that before operation (P < 0.05). There was no significant difference in the accuracy of number cancellation compared with that before operation. The patients who needed the third test in the elder group were significantly more than in the other groups (P < 0.05). Compared with the preoperative results, there was no statistical difference in the test results of those who completed the third test.
CONCLUSION
The psychomotility function of the patients who underwent painless gastroscopy and colonoscopy was recovered when they met discharge criteria. The elderly patients had a prolonged recovery period.
