Polygonatum sibiricum， as a traditional Chinese medicine with both medicinal and edible properties， has attracted considerable attention due to its functions of nourishing Yin and moistening the lungs， tonifying the spleen and benefiting Qi， and nourishing the kidneys and filling essence. Recent studies have demonstrated that Polygonatum sibiricum plays a significant role in regulating the immune system， effectively enhancing and improving the morphology and function of immune organs， stimulating the proliferation and activation of immune cells， and regulating the secretion and release of immune factors， thereby enhancing the immune function of the body and improving various immune-related diseases. Although a large number of studies have explored the pharmacological effects and mechanisms of P. sibiricum， there has been no systematic review and summary of its immune regulatory activity and mechanisms. Therefore， this article comprehensively reviews the research achievements of P. sibiricum polysaccharides and saponins in the field of immune regulation in recent years， and further sorts out the immune regulatory mechanisms of P. sibiricum in multiple aspects： including increasing the organ index of the spleen and thymus， increasing the number and activity of tumor-suppressive bone marrow hematopoietic stem cells， improving intestinal flora imbalance， regulating the quantity and proportion of T lymphocyte subsets， increasing the level of immunoglobulin， promoting the proliferation of macrophages， enhancing the activity of natural killer cells， increasing the number of white blood cells， and promoting the maturation of dendritic cells， providing a solid theoretical basis and scientific evidence for the research and application of P. sibiricum， and promoting its development and application in traditional Chinese medicine immune enhancers and various functional products.

Objective To evaluate the safety and feasibility of remote robot-assisted thoracoscopic surgery utilizing 5G technology. Methods Clinical data from five patients who underwent 5G remote robot-assisted thoracoscopic surgery at the Thoracic Surgery Center of Gansu Provincial People's Hospital from May to October 2024 were retrospectively analyzed. Results Finally, five patients were included. There were 2 males and 3 females at median age of 50 (42-63) years. All five surgeries (including 1 patient of lobectomy, 3 patients of partial lung resection and 1 patient of mediastinal lesion resection) were successfully completed without conversion to thoracotomy, complications, or mortality. The median intraoperative signal delay across the patients was 39 (37-42) ms. The median psychological load score for the surgeons was 9 (3-13). The median operation time was 100 (80-122) minutes with a median intraoperative blood loss of 100 (30-200) mL. Catheter drainage lasted a median of 4 (3-5) days, and the median drainage volumes on the first, second, and third postoperative day were 200 (100-300) mL, 150 (60-220) mL, and 80 (30-180) mL, respectively. The median postoperative hospital stay was 4 (3-7) days, and the median pain scores on the third postoperative day were 3 (1-4), 3 (0-3), and 1 (0-3), respectively. Conclusion 5G remote robot-assisted thoracoscopic surgery is safe and effective, with good surgical experience, smooth operation and small intraoperative delay.

OBJECTIVE To investigate the inhibitory effect and mechanism of Modified qifang weitong granules on gastric cancer based on in vitro and in vivo experiments. METHODS Human gastric cancer HGC-27 cells were divided into the following groups: control group （treated with fetal bovine serum）， 10% drug-containing serum group， 15% drug-containing serum group， 20% drug-containing serum group， and 5-fluorouracil （5-Fu） group （positive control， 3.90 μg/mL）. After culturing the cells in each group with the corresponding serum/drug solution， their proliferation， migratory and invasive abilities， as well as the cell cycle， were assessed. Additionally， the expression levels of epithelial-mesenchymal transition （EMT）-related proteins [E-cadherin， N-cadherin， and vimentin] in the cells were measured. Logarithmic-phase HGC-27 cells were harvested and subcutaneously injected into the right axillary region of nude mice to establish a subcutaneous xenograft tumor model in nude mice. The successfully modeled tumor-bearing nude mice were randomly divided into model group， low-， medium- and high-dose groups of Modified qifang weitong granules （17.65， 35.29 and 70.58 g/kg， respectively）， and 5-Fu group （25 mg/kg）， with 5 mice in each group. After 14 days of treatment with the corresponding drugs in each group， the histopathological morphology of the tumor tissues in the nude mice was observed. Immunohistochemistry and Western blot assay were employed to detect the expression levels of EMT- related proteins in the tumor tissues of the nude mice. RESULTS In the cell experiment， compared with the control group， the cell proliferation rate， migration rate， number of invasive cells， as well as the expression levels of N-cadherin and vimentin proteins， and the percentage of cells in the G2/M phase were all significantly decreased/reduced in the 15% drug-containing serum group， 20% drug-containing serum group （P＜0.05）. Conversely， the percentage of cells in the G0/G1 phase and the expression level of E- cadherin protein were significantly increased （P＜0.05）. In animal experiment， compared with the model group， the high-dose group of Modified qifang weitong granules exhibited significantly reduced tumor mass and expression levels of N-cadherin and vimentin proteins in the tumor tissues of nude mice （P＜0.05）， while the expression level of E-cadherinprotein in the tumor tissues was significantly increased （P＜0.05）. Additionally， the tumor cells varied in size and showed extensive necrosis. CONCLUSIONS Modified qifang weitong granules effectively inhibit gastric cancer in both in vitro and in vivo models， and the mechanism of action is related to the suppression of EMT.

Allergen-specific immunotherapy（AIT） remains the only therapeutic approach with the potential to modify the natural course of allergic rhinitis（AR）. Nevertheless, considerable inter-individual variability exists in patients'responses to AIT. To facilitate more reliable assessment of treatment efficacy, the China Rhinopathy Research Cooperation Group（CRRCG） convened young and middle-aged nasal experts in China to formulate the present consensus. The recommended subjective outcome measures for AIT comprise symptom scores, medication scores, combined symptom and medication scores, quality-of-life assessments, evaluation of disease control, and assessment of comorbidities. Objective indicators may supplement these measures. Currently available objective approaches include skin prick testing, nasal provocation testing, and allergen exposure chambers. However, these methods remain constrained by practical limitations and are not yet appropriate for routine implementation in clinical efficacy evaluation. In addition, several biomarkers, including sIgE and the sIgE/tIgE ratio, sIgG4, serum IgE-blocking activity, IgA, cytokines and chemokines, as well as immune cell surface molecules and their functional activity, have been shown to have associations with AIT outcomes. While these biomarkers may complement subjective assessments, they are subject to significant limitations. Consequently, large-scale multicenter trials and real-world evidence are required to strengthen the evidence base. The present consensus underscores the necessity of integrating patients'subjective experiences with objective testing throughout the treatment process, thereby providing a more comprehensive and accurate framework for efficacy evaluation. Looking forward, future investigations should prioritize the incorporation of multi-omics data and artificial intelligence methodologies, which hold promise for overcoming current limitations in assessment strategies and for advancing both the standardization and personalization of AIT.

Objective:To investigate the effect of the number of positive preoperative serological tumor markers on the surgical approach and prognosis of patients with intrahepatic cholangiocarcinoma.Methods:This is a retrospective case-series study. Data from 548 patients with intrahepatic cholangiocarcinoma after radical resection from October 2010 to April 2019 were retrospectively collected in 10 hospitals of China. There were 277 males and 271 females with an age of (57.8±10.2)years(range:23 to 84 years). Four hundred and twenty-six patients(77.7%) had at least one positive preoperative serum tumor marker. The data collection included the results of 4 preoperative serological tumor markers,other preoperative indicators(5 prodromal symptoms, 6 medical history,8 preoperative serological indicators,5 preoperative imaging indicators,and 14 preoperative pathological examination indicators),baseline data (gender and age),surgical methods,and prognostic follow-up data. Four preoperative results of serologic tumor marker and surgical procedure were converted into categorical variables. The number of positive preoperative serum tumor markers was used as the treatment variable,the surgical method was used as the mediating variable,and the survival time was used as the outcome variable. Univariate and multivariate analysis were used to screen for other preoperative indicators which were independent factors that influenced the surgical procedure and the prognosis of patients as covariates to analyze the mediating effect.Results:Of the 548 patients included in the study, 176 patients (32.1%) underwent partial hepatectomy,151 patients(27.5%) underwent hemihepatectomy, and 221 patients(40.3%) underwent partial hepatectomy or hemihepatectomy combined with other treatments. The results of the univariate and multivariate analysis showed that the number of positive serum tumor markers,intrahepatic bile duct dilatation,portal vein invasion,pathological differentiation,pathological type,vascular invasion,T stage,N stage and maximum tumor diameter were independent factors influencing the surgical procedure(all P<0.05). Intrahepatic bile duct dilatation,pathological differentiation and T stage were independent prognostic factors for patients with intrahepatic cholangiocarcinoma(all P<0.05). Intrahepatic bile duct dilatation,differentiation and T stage were included as covariates in the mediation effect model. The results showed that the number of positive serum tumor markers before surgery had a negative predictive effect on the survival time of patients with intrahepatic cholangiocarcinoma ( β=-0.092, P=0.039),and had a positive predictive effect on the surgical method ( β=0.244, P<0.01). The number of positive serum tumor markers had a negative predictive effect on the survival time of patients with intrahepatic cholangiocarcinoma ( β=-0.151, P=0.002). Direct and indirect effects accounted for 71.3% and 28.7% of total effects,respectively. Conclusions:The higher the positive number of preoperative tumor markers,the worse the prognosis of patients with intrahepatic cholangiocarcinoma. The number of positive cells not only directly affects the prognosis of patients,but also indirectly affects the prognosis of patients by affecting the surgical method.

Objective　To understand the impact of early and timely treatment and initial antiviral treatment regimen on mortality and attrition of antiretroviral therapy. Methods A retrospective cohort study was conducted using download data on antiretroviral therapy for HIV-infected patients in Liuzhou City, Guangxi Province, from the database of the Basic Information System for AIDS Control and Prevention (BISAC) from 2010 to 2020. The Cox proportional risk regression model was used to analyze the influencing factors of mortality and attrition. Results A total of 15 713 infected patients were included, including 53.4% aged 18-<50 years, 69.4% male, 61.0% farmer, 75.1% CD4 count <350 cells /μL before initial antiviral treatment, the overall mortality rate was 4.30/100 person-years, and the overall attrition was 2.42/100 person-years. The results of Cox regression analysis showed that the influencing factors of mortality were pretreatment CD4 counts of 350-<500 cells/μL(AHR=0.72, 95%CI: 0.63-0.81) and ≥500 cells/μL (AHR= 0.64, 95%CI: 0.55-0.76); duration from diagnosis to initial antiviral treatment 91-180 days (AHR=1.25, 95%CI: 1.08-1.45), 181-365 days (AHR=1.26, 95%CI: 1.08-1.47), and ≥365 days (AHR=1.26, 95%CI: 1.11-1.44); initial antiviral treatment regimens of D4T+3TC+EFV/NVP (AHR=1.47, 95%CI: 1.32-1.63) and AZT/D4T/TDF+3TC+LPV/r (AHR=1.73, 95%CI: 1.50-1.99). Factors affecting attrition were pretreatment CD4 counts of 350-499 cells/μL (AHR=1.32, 95%CI: 1.16-1.50) and ≥500 cells/μL (AHR=1.28, 95%CI: 1.10-1.50); interval from HIV positivity confirmation to initial dosing ≥365 days (AHR=1.21, 95%CI: 1.04-1.40), initial antiviral treatment regimens of TDF+3TC+NVP (AHR=1.32, 95%CI: 1.13-1.55), AZT+3TC+EFV/NVP (AHR=1.43, 95%CI: 1.26-1.62) and AZT/D4T/TDF+3TC+LPV/r (AHR=1.33, 95CI%: 1.06-1.67). Conclusions　Early and timely treatment and the initial antiviral treatment regimen of TDF+3TC+EFV have good efficacy, but attention should be paid to the high risk of attrition of HIV-infected people with high CD4 count before treatment.

Objective:To analyze the incidence trend and epidemiological characteristics of typhoid fever in Fujian Province from 2011 to 2022, and understand the high-incidence population and hotspot areas, and provide evidences to develop more targeted prevention and control measures.Methods:The surveillance data of typhoid fever during 2011-2022 in Fujian Province were obtained from the National Disease Reporting Information System and analyzed with SAS 9.4. The spatial autocorrelation analysis of typhoid fever incidence at county/district levels was performed with ArcGlS 10.8.Results:A total of 5 126 cases of typhoid fever were reported in Fujian Province from 2011 to 2022, with an average annual incidence rate of 1.10/100 000. The average annual incidence rate was 0.96/100 000 from 2011 to 2015, 1.49/100 000 from 2016 to 2019, and 0.81/100 000 from 2020 to 2022. The disease occurred all the year round, with high epidemic season from May to September. A total of 23.59% (1 209/5 126) of the cases occurred at the age of 0-4, and 9.62% (493/5 126) at the age of 5-9. The male to female ratio of the cases was 0.97∶1 (2 524∶2 602) for the whole population, 1.19∶1 (925∶777) for people under 10 years old, 0.75∶1 (1 060∶1 404) for people between 10 and 54 years old, and 1.28∶1 (539∶421) for people over 55 years old. Cases in Ningde City accounted for 30.65% (1 571/5 126) of the total cases. Most hotspots were occurred in Ningde City. Recurrent and clustered cases were found in family members.Conclusions:Typhoid fever was prevalent at a low level in Fujian Province during 2011-2022, indicating that strengthening the prevention and control measures should target key areas and populations. The incidence of typhoid fever in Fujian Province showed spatial aggregation phenomenon, and most cases gathered in Ningde City. Intensive study for the influencing factors of spatial clustering should be conducted.

Objective To analyze the characteristics of pattern elements and the distribution of patterns of femoral head necrosis, hip osteoarthritis, and hip rheumatoid arthritis, in order to provide a theoretical basis for the "different diseases with the same pattern" of chronic bone diseases. Methods A cross-sectional survey was conducted to select patients with femoral head necrosis Association Research Circulation Osseous Ⅰ-Ⅱ stages, hip osteoarthritis Kellgren & Lawrence Ⅰ-Ⅱ stages, and acute or subacute hip rheumatoid arthritis who visited the Minimally Invasive Arthrology Department, Traumatology Department, and Rheumatology and Immunology Department of Beijing University of Chinese Medicine Third Affiliated Hospital from June 2020 to June 2022. The " case report form - traditional Chinese medicine pattern manifestation scale" previously developed by our team was used to collect the pattern manifestations, which were included into an Excel 2020 spreadsheet to establish a database. SPSS 20.0 software was used for factor analysis and cluster analysis to extract pattern element information, such as disease nature and location, in order to summarize the characteristics of pattern elements, the distribution of patterns, and the similarities and differences of the three kinds of early hip joint diseases.Results A total of 410 patients were included, including 150 patients with femoral head necrosis, 160 patients with hip osteoarthritis, and 100 patients with hip rheumatoid arthritis. The pattern elements of the disease nature of femoral head necrosis include phlegm (dampness), blood stasis, yang deficiency, essence deficiency, and qi deficiency. The pattern types were initially divided into four categories: syndrome of meridian obstruction (43.33％), syndrome of phlegm and blood stasis blocking collaterals (38.00％), syndrome of liver and kidney deficiency (12.00％), and syndrome of kidney essence deficiency (6.67％). The pattern elements of the disease nature of hip osteoarthritis include phlegm (dampness), blood stasis, qi deficiency, essence deficiency, yang deficiency, and cold (dampness). The pattern types were preliminarily divided into five categories: syndrome of spleen and kidney deficiency (37.50％), syndrome of meridian obstruction (26.87％), syndrome of cold and dampness obstruction (18.75％), syndrome of phlegm and blood stasis obstruction (9.38％), and syndrome of liver and kidney deficiency (7.50％). The pattern elements of the disease nature of hip rheumatoid arthritis include phlegm (dampness), blood stasis, qi deficiency, yin and yang deficiency, cold (dampness), and essence deficiency. The pattern types were preliminarily divided into four categories: syndrome of phlegm and blood stasis obstruction (34.00％), syndrome of cold and dampness obstruction (28.00％), syndrome of blood stasis blocking collaterals (23.00％), and syndrome of liver and kidney deficiency (15.00％). Overall, the top five pattern manifestations of the three kinds of hip joint diseases were hip joint pain (96.59％), tenderness (93.90％), fixed pain (87.56％), heavy joints (85.37％), and sourness of lower limbs (75.37％). The pattern elements of the disease nature include phlegm (dampness), blood stasis, qi deficiency, etc. The pattern types were preliminarily divided into five categories: syndrome of phlegm stasis blocking collaterals (33.17％), syndrome of meridian obstruction (31.95％), syndrome of cold dampness obstruction (21.46％), syndrome of liver and kidney deficiency (7.32％), and syndrome of spleen and kidney deficiency (6.10％). There were 21 similar pattern manifestations in the three kinds of early hip joint diseases, with blood stasis and spleen deficiency being the main pattern.Conclusion The common pattern characteristics of three kinds of early hip joint diseases are spleen deficiency and blood stasis. In addition, femoral head necrosis is accompanied with phlegm-dampness pattern, hip osteoarthritis is accompanied with kidney deficiency and phlegm-dampness pattern, hip rheumatoid arthritis is accompanied with kidney deficiency and cold-dampness pattern.
