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 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.

ObjectivesTo analyze the spatial and temporal clustering characteristics and related influencing factors of late diagnosis of HIV/AIDS in Lanzhou, to identify its high-risk areas and time trends in Lanzhou, and to provide a theoretical basis for developing targeted HIV/AIDS prevention and control strategies in Lanzhou. MethodsThe subjects of this study were adult HIV/AIDS cases reported in Lanzhou City between 2011 and 2018. Data used in the study were sourced from the Lanzhou Center for Disease Control and Prevention and the Lanzhou Statistical Yearbook. To analyze the spatial distribution characteristics and influencing factors of the relative risk (RR) of late HIV/AIDS diagnosis, Bayes spatial-temporal model was used. ResultsA total of 1984 new HIV/AIDS cases were reported in Lanzhou from 2011 to 2018, with an mean age of 37.51 years and predominantly male (91.8%). The number of late diagnosis cases was 982, with an mean age of 39.67 years and a predominance of males (91.8%). Late diagnosis was more common in older individuals and women with HIV/AIDS. Chengguan District (51.1%), Anning District (50.3%) and Yuzhong County (51.9%) had an above-average proportion of late diagnosis of HIV/AIDS. The proportion of late diagnosis cases in Lanzhou showed a fluctuating upward trend from 2011 to 2018. The results of Bayes spatial-temporal model showed that the risk of late HIV/AIDS diagnosis in Lanzhou had fluctuated from 2011 to 2015, and then increased rapidly after 2015 [RR (95% credibility interval, 95%CI) increased from 1.01 (0.84, 1.23) to 1.11 (0.77, 1.97)]; the trends of risk of late diagnosis in Honggu district and three counties were similar to the overall trend in Lanzhou city, while the risk of late diagnosis in Chengguan District and Qilihe District showed a decreasing trend. The regions with the RR for late diagnosis greater than 1 included Yongdeng County (RR=1.07, 95% CI: 0.55, 1.96), Xigu District (RR=1.04, 95% CI: 0.67, 1.49), Chengguan District (RR=2.41, 95% CI: 0.85, 6.16), and Qilihe District (RR=2.03, 95% CI: 1.10, 3.27). Besides, the heatmap analysis showed that Chengguan District and Qilihe District were the hot spots. The influencing factors analysis showed that the higher GDP per capita (RR=0.65, 95% CI: 0.35, 0.90) and the larger proportion of males with HIV/AIDS cases (RR=0.53, 95% CI: 0.19, 0.92) could lead to the lower the relative risk of late HIV/AIDS diagnosis. However, the higher the population density (RR=1.35, 95% CI: 1.01, 1.81) caused the higher the risk of late diagnosis. ConclusionOur study shows the risk of late diagnosis of HIV/AIDS in Lanzhou was on the rise, and there are significant regional differences. GDP per capita, the proportion of males in HIV/AIDS cases and population density are influencing factors in the late diagnosis of HIV/AIDS. Therefore, for regions with a high risk of late diagnosis or related risk factors, targeted HIV screening and prevention services should be given priority in order to reduce the proportion and risk of late diagnosis of HIV/AIDS.

With the optimization of surgical technologies and postoperative management regimens, the number of lung transplantation has been significantly increased, which has become an important treatment for patients with end-stage lung disease. However, due to the impact of comprehensive factors, such as bronchial ischemia and immunosuppression, the incidence of airway stenosis after lung transplantation is relatively high, which severely affects postoperative survival and quality of life of lung transplant recipients. In recent years, with the improvement of perioperative management, organ preservation and surgical technologies, the incidence of airway stenosis after lung transplantation has been declined, but it remains at a high level. Early diagnosis and timely intervention play a significant role in enhancing clinical prognosis of patients with airway stenosis. In this article, the general conditions, diagnosis, treatment and prevention of airway stenosis after lung transplantation were reviewed, aiming to provide reference for comprehensive management of airway stenosis after lung transplantation and improving clinical prognosis of lung transplant recipients.

ObjectiveTaking Shengxuebao as the model traditional Chinese medicine(TCM), this study aims to explore the methodologies and transfer patterns in the composition changes of TCM compound preparations from liquid to solid dosage forms. MethodBased on the previously established ultra-high performance liquid chromatography(UPLC) qualitative and quantitative methods for Shengxuebao, the fingerprint profiles of three preparations of Shengxuebao(homemade decoction, commercially available granules and mixtures) were established, and nineteen components were quantitatively analyzed. The similarities of fingerprint profiles among these three preparations were assessed using the Similarity Evaluation System for Chromatographic Fingerprint of TCM(2012 edition) and the total quantum statistical moment similarity method, respectively. The molecular connectivity index (MCI) and the average molar MCI of the chemical components in the three preparations were calculated. Seventy-two MCI values across 0-8 orders, including 8 subclasses, were calculated. The average molar MCI of 0-3 orders was used to study the "imprint template" structural characteristics and transfer patterns of the medicinal component groups. ResultThe similarities of the fingerprint profile of the decoction with those of the control, granules, and mixtures were 0.971, 0.888 and 0.799, respectively, indicating that the chemical composition of the granules and mixtures differed from that of the decoction, and that the 19 components were able to basically respond to the overall situation of the component group of Shengxuebao decoction. The total mass fractions of the detectable major components in Shengxuebao decoction, granules and mixtures was measured to be 5.498 6, 2.282 0, 1.416 6 mg·g-1, respectively. The average molar MCI of 0-3 orders showed a gradual decrease across the three preparations, with the trend of decoction>granules>mixtures, indicating subtle changes in the overall structural characteristics of the chemical components in the samples of the three preparations. ConclusionAmong the three formulations of Shengxuebao, the traditional decoction contained the highest variety and quantity of components and carried the most substantial amount of component information, with a decreasing order observed in the granules and mixtures. This study further validates that traditional decoction is a reliable and fundamental dosage form, providing a reference for the modernization of TCM dosage forms and the quality consistency evaluation of compound preparations.
