epsis is a systemic inflammatory response syndrome triggered by infection， and its high mortality rate is closely associated with immune imbalance， particularly the imbalance in the differentiation of helper T cell （Th） cell subsets [Th1， Th2， Th17， regulatory T cell （Treg） ] . In recent years， traditional Chinese medicine （TCM）， with its characteristics of multi-component and multi-target actions， has demonstrated unique advantages in regulating Th cell differentiation and function， as well as correcting immune imbalances in sepsis， offering new perspectives for immunotherapy of sepsis. This review summarizes relevant studies on the regulation of Th cell differentiation for sepsis treatment by TCM monomers and active ingredients （such as Astragalus membranaceus ， Scutellaria baicalensis ， Coptis chinensis ， Rheum palmatum ， Ganoderma lucidum ， Ginkgo biloba ， and Cistanche deserticola ）， the alcohol extract of Dai Baijie， and TCM formulas and preparations categorized as blood-activating and stasis-removing， purgative and laxative， warming and tonifying yang， and tonifying qi and nourishing yin. The results indicate that these TCM monomers， active ingredients， extracts， formulas， and preparations can regulate the Th1/Th2 and Th17/Treg balance， target the differentiation balance of Th cell subsets， alleviate inflammatory responses， or improve immune suppression， thereby exerting therapeutic effects on sepsis.

Osteonecrosis of femoral head （ONFH） is a disease that causes osteocyte death due to interruption of blood supply of the femoral head， which may cause symptoms such as joint movement disorders， pain， and even femoral head collapse. Currently， the commonly used methods for treating ONFH in clinical practice are accompanied by problems such as long-term side effects， inaccurate efficacy， technical limitations， and complication risks. Traditional Chinese medicine （TCM） has shown unique advantages of holistic regulation， mild side effects， and symptom alleviation. A review of the related literature shows that Salviae Miltiorrhizae Radix et Rhizoma， as a representative Chinese herbal medicine for activating blood and resolving stasis， has the effects of activating blood， resolving stasis， dredging meridians， and relieving pain. Its active ingredients （such as salvianolic acid B， tanshinone Ⅱ_A， and tanshinone Ⅰ） interfere with bone metabolism balance， osteogenesis and differentiation， and improve bone microcirculation and bone microstructure. Salviae Miltiorrhizae Radix et Rhizoma is often combined with the herbal medicines with the effects of tonifying the liver and spleen or activing blood to form herb pairs （such as Salviae Miltiorrhizae Radix et Rhizoma-Angelicae Sinensis Radix， Salviae Miltiorrhizae Radix et Rhizoma-Chuanxiong Rhizoma， and Salviae Miltiorrhizae Radix et Rhizoma-Drynariae Rhizoma）， which enhances the efficacy through synergistic effects. In the application of TCM compound formulas， Bushen Huoxue prescription， Bushen Huoxue capsules， Gubi Tongxiao granules， and Shenggu Zaizao pills can regulate signaling pathways such as Wnt/β-catenin， Hedgehog， Notch， transforming growth factor（TGF）-β₁/Smads， and mitogen-activated protein kinase （MAPK） through multiple targets to significantly improve bone metabolism and hip joint function， playing an important role in preventing and treating ONFH. Through a review of available studies， this paper systematically explains the outstanding advantages of the active ingredients， herb pairs， and compound formulas of Salviae miltiorrhizae Radix et Rhizoma in the prevention and treatment of ONFH. The mechanisms may be related to factors such as promoting osteoblast generation and inhibiting osteoclast formation， increasing osteogenic differentiation， promoting angiogenesis， increasing bone density， inhibiting inflammatory response， and regulating signaling pathways. In the future， modern technology can be employed to optimize dosage forms， and high-quality clinical research should be conducted to further clarify its mechanism of action and promote the precise application of TCM. This review aims to provide more thinking directions for the application of Salviae miltiorrhizae Radix et Rhizoma in preventing and treating ONFH.

Sepsis is a systemic inflammatory response syndrome triggered by infection. It progresses rapidly and tends to develop into multiple organ dysfunction. Tanshinone ⅡA， one of the core active ingredients of Salvia miltiorrhiza， exerts remarkable targeted protective effects against sepsis-induced multiple organ dysfunction. This paper reviews the mechanisms by which tanshinone ⅡA alleviates sepsis-induced multiple organ dysfunction. Tanshinone ⅡA can relieve sepsis-induced lung injury by inhibiting the activity of Toll-like receptor 4/myeloid differentiation primary response protein 88/nuclear factor- κB， phosphatidylinositol 3-kinase/protein kinase B signaling pathways and maintaining mitochondrial homeostasis. It ameliorates sepsis- induced myocardial injury via suppressing the activation of NOD-like receptor family pyrin domain-containing 3/caspase-1 signaling pathway， downregulating the expression of inflammatory factors and regulating autophagy. It mitigates sepsis-induced renal injury by regulating oxidative stress imbalance and reducing the expression of apoptosis-related proteins. It alleviates sepsis-caused liver injury through inhibiting the release of inflammatory factors and hepatocyte apoptosis. It improves sepsis-induced intestinal barrier dysfunction by upregulating the expression of tight junction proteins and restraining inflammatory responses. Furthermore， it relieves sepsis-associated encephalopathy by activating peroxisome proliferator-activated receptor gamma coactivator-1α/nuclear respiratory factor 1/mitochondrial transcription factor A signaling pathway. Tanshinone ⅡA is expected to be a vital candidate drug for comprehensive prevention and treatment of sepsis. However， interdisciplinary research is required to break through current bottlenecks and realize the transformation from basic experiments to clinical application.

Abstract To analyze the current status of added sugar intake among children and adolescents and to explore its potential impact on their visual health, so as to provide a scientific basis for future research directions and policy formulation. Findings from animal experiments and cell based studies have suggested that added sugars might contribute to ocular axial growth and scleral remodeling by disrupting insulin/insulin like growth factor-1 signaling, thereby inducing oxidative stress and chronic inflammation, affecting neuroregulatory pathways, and diluting micronutrient intake. Further high quality prospective studies and intervention trials are warranted to clarify the specificity of the association and the underlying biological mechanisms, thereby providing evidence based support for public health strategies.

Objective To investigate the clinical efficacy of Guhong Injection for the treatment of patients with coronary microvascular dysfunction(CMD)of qi stagnation and blood stasis syndrome.Methods Sixty cases of patients with CMD of qi stagnation and blood stasis syndrome who were admitted to Guangdong Provincial Hospital of Chinese Medicine from June 2021 to August 2022 were randomly divided into the control group and the trial group according to the random number table method,with 30 cases in each group.The control group was treated with conventional western medicine,and the trial group was treated with Guhong Injection on the basis of treatment for the control group.The course of treatment for the two groups covered 10 days.The changes in traditional Chinese medicine(TCM)syndrome scores,and levels of lipid indicators,serum inflammatory factors and endothelial factors in the two groups were observed before and after treatment.After treatment,the clinical efficacy of the two groups was evaluated.Results(1)During the trial,three cases in the control group and two cases in the trial group fell off and a total of 55 cases were finally included in the statistical analysis of efficacy,including 27 cases in the control group and 28 cases in the trial group.(2)After 10 days of treatment,the total effective rate of the trial group was 89.29%(25/28),and that of the control group was 40.74%(11/27),and the intergroup comparison(tested by chi-square test)showed that the therapeutic efficacy of the trial group was significantly superior to that of the control group(P<0.01).(3)After treatment,the TCM syndrome scores of patients in both groups were decreased compared with those before treatment(P<0.05),and the decrease in the trial group was significantly superior to that in the control group(P<0.01).(4)After treatment,the levels of lipid indicators triglyceride(TG),total cholesterol(TC),and low-density lipoprotein cholesterol(LDL-C)in the two groups of patients were decreased compared with those before treatment(P<0.05),and the level of high-density lipoprotein cholesterol(HDL-C)was increased compared with that before treatment(P<0.05).The intergroup comparison showed that the decrease of TG,TC,and LDL-C levels as well as the increase of HDL-C level in the trial group was significantly superior to that in the control group(P<0.05 or P<0.01).(5)After treatment,the serum levels of inflammatory factors high-sensitivity C-reactive protein(hs-CRP),interleukin 6(IL-6)and tumor necrosis factor α(TNF-α)in the two groups of patients were decreased compared with those before treatment(P<0.05),and the decrease in the trial group was significantly superior to that in the control group(P<0.01).(6)After treatment,the serum level of endothelial factor nitric oxide(NO)in the two groups of patients was increased(P<0.05)and the serum endothelin 1(ET-1)level was decreased compared with that before treatment(P<0.05),and the increase of serum NO level,as well as the decrease of serum ET-1 level in the trial group was significantly superior to that in the control group(P<0.05 or P<0.01).Conclusion Based on the conventional treatment in western medicine,the application of Guhong Injection in the treatment of patients with CMD of qi stagnation and blood stasis syndrome exerts remarkable efficacy,which can effectively alleviate the symptoms,regulate the levels of blood lipids,reduce the inflammatory response,and improve the endothelial function.

Objective To analyze the changes in serum miR-205,miR-23b and miR-25 levels and their correlation with the prognosis of patients with different severities of sepsis.Methods A retrospective study was conducted in 86 patients with sepsis admitted to our hospital between September 2021 and September 2023.Based on the severity of illness,patients were divided into mild(52 cases)and severe(34 cases)groups.Eighty healthy individuals undergoing medical check-ups during the same period were selected as controls.The patients were follo wed-up for 28 days and were then categorized into a survival group(68 patients)and a death group(18 patients).Real-time polymerase chain reaction was used to detect the serum miR-205,miR-23b,and miR-25 levels in patients and analyze their corre-lation with prognosis.Multivariate Cox regression analysis was used to analyze the risk factors affecting patient prognosis.The diagnostic value of serum miR-205,miR-23b,and miR-25 levels in assessing sepsis and their predictive value for prognosis were analyzed using receiver operating characteristic curves.Results Serum miR-205,miR-23b,and miR-25 levels were significantly lower in the two groups of patients with sepsis than in the control group(P＜0.05),and were significantly higher in the survival group than in the death group(P＜0.05).Their levels negatively correlated with prognosis.Heart rate and APACHE Ⅱ score were risk factors for a poor prognosis of patients with sepsis,whereas high serum miR-205,miR-23b,and miR-25 levels were protective factors(P＜0.05).The areas under the curve(AUC)for individual serum miR-205,miR-23b,and miR-25 levels and their combination to assess sepsis were 0.794,0.786,0.768,and 0.926,respectively.The AUC for predicting poor prognosis for patients were 0.776,0.762,0.797,and 0.918,respectively.Conclusion Serum miR-205,miR-23b,and miR-25 levels were reduced in patients with sepsis,and were closely correlated with patient prognosis.Thus,they may serve as serological biomarkers for assessing disease and predicting prognosis.

Objective To use AI-assisted motor dysfunction assessment for quantitative evaluation of motor function in Parkinson's disease(PD)and multiple system atrophy-Parkinsonian type(MSA-P)in order to achieve accurate differential diagnosis.Methods A total of 105 participants aged ≥60 years were consecutively enrolled from the First and Third Medical Centers of Chinese PLA General Hospital between January and September 2024.Based on diagnostic criteria,they were divided into a PD group(48 cases),a MSA-P group(31 cases),and a control group(26 cases).The general information was collected,and the motor function was evaluated with Move-ment Dysfunction Assessment Software in order to assess the diagnostic value of the AI-assisted assessment in differentiating between PD and MSA-P.Results Significantly differences were observed among the three groups in terms of facial expression indicators,bilateral finger tapping frequency,bilateral hand movement frequency,right hand movement amplitude change rate,bilat-eral palm flipping frequency,bilateral toe tapping frequency,freezing load of bilateral toe tapping,bilateral leg flexibility frequency,right leg flexibility amplitude change rate,freezing load of bilat-eral leg flexibility,upright extension angular velocity,turnaround time,forward step frequency,backward step frequency,forward average stride length,backward average stride length,forward average walking speed,backward average walking speed,forward average step width,backward average step width,bilateral postural tremor frequency,bilateral postural tremor maximum am-plitude,bilateral action tremor frequency,bilateral action tremor maximum amplitude,and com-parison of bilateral resting tremor frequency(P＜0.05,P＜0.01).The MSA-P group exhibited significantly lower blink frequency,maximum amplitude and frequency of facial tremors,upright extension angular velocity,and step frequency,while higher ratio of mouth opening duration and longer turnaround time when compared with the PD group(P＜0.05,P＜0.01).The AUC value of the combined nine motor function indicators and the five facial expression indicators in differ-entiating PD from MSA-P was 0.943(95％CI:0.895-0.991,P=0.000)and 0.925(95％CI:0.870-0.981,P=0.000),respectively,both better than that of individual indicators.Conclusion Combi-nation assessment of facial expression,posture,gait with AI assistance can contribute to the dif-ferential diagnosis of PD and MSA-P.

Objective·To preliminarily investigate the value of high-order functional magnetic resonance imaging in the evaluation of benign and malignant bone and soft tissue tumors and the changes after chemotherapy.Methods·Patients clinically diagnosed with bone and soft tissue tumors at the Department of Orthopaedics,Shanghai Ninth People's Hospital,Shanghai Jiao Tong University School of Medicine,from October 2014 to December 2024 were enrolled.The patients were divided into a control group and an amide proton transfer-weighted imaging(APTw)group according to the imaging method.All patients underwent conventional magnetic resonance imaging(MRI),diffusion-weighted imaging(DWI),and dynamic contrast-enhanced imaging(DCE)before surgery.Patients in the APTw group received additional APTw imaging.Both groups were divided into non-malignant and malignant lesion subgroups according to pathological results.According to whether the patients received chemotherapy before enrollment,the patients with malignant lesions in the APTw group were further divided into malignant group without chemotherapy and malignant group with chemotherapy.Clinical and imaging data,including APT values,apparent diffusion coefficient(ADC),and time-intensity curves(TICs)from the largest tumor section,were collected and analyzed to assess the diagnostic performance of APTw,DWI,and DCE,and to evaluate changes after chemotherapy.Results·Eighty-five patients were enrolled,including 51 males and 34 females,with ages ranging from 10 to 84 years,and a mean age of(43.05±17.62)years.There were 51 patients in the control group(16 with non-malignant lesions and 35 with malignant lesions)and 34 patients in the APTw group(5 with non-malignant lesions and 29 with malignant lesions;23 malignant lesions without chemotherapy and 6 malignant lesions with chemotherapy).The clinical and imaging data showed that only the tumor margin of the control group and the maximum tumor diameter of the APTw group had statistically significant differences in their malignant and non-malignant lesion groups(P<0.05).In the APTw group,there was a statistically significant difference in APT values between the malignant lesion group and the non-malignant lesion group(P<0.001).Further analysis showed that the APT values in the malignant group without chemotherapy were significantly lower than that in the malignant group with chemotherapy(P<0.001).However,there were no statistically significant differences in APT values between the malignant group with chemotherapy and the non-malignant lesion group(P>0.05).There were no significant differences in ADC values and TIC types between malignant and non-malignant lesion groups in the control group and the APTw group(P>0.05).The area under the curve(AUC)of the diagnostic model in the APTw group(MRI+DWI+DCE+APTw)for distinguishing malignant from benign tumors was significantly higher than that of the control group(MRI+DWI+DCE)(P<0.05).The Youden index and specificity of the diagnostic model in the APTw group were higher than those in the control group.Conclusion·As a high-order functional MRI technique,APTw imaging is capable of evaluating the nature(benign or malignant)of bone and soft tissue tumors and detecting changes after chemotherapy.It serves as a valuable supplement to conventional MRI,DWI,and DCE imaging,providing a novel noninvasive tool for the diagnosis and treatment evaluation of bone and soft tissue tumors.

Objective:To construct a biosafety evaluation index system for major emergency public health events in medical institutions.Methods:Based on previous laboratory biosafety evaluation work, relevant regulations and standards on biosafety in China were collected through literature research and expert consultations. Candidate indicators for constructing the biosafety evaluation system for major emergency public health events in medical institutions were selected, and a framework was established. Two rounds of expert questionnaires were conducted to determine the content of the index system based on experts′ evaluation, and each indicator′s relevance and importance were scored. Finally, two rounds of Delphi consultations were carried out, and the Analytic Hierarchy Process (AHP) was applied to calculate the weights of indicators.Results:The response rates for the total four rounds of questionnaire surveys were all 100%. The first two rounds focused on determining the framework, while the latter two focused on determining the weights for each indicator. The authority coefficients of the expert consultations for the two rounds of weights were 0.65 and 0.70, respectively, indicating the reliability of the research results. In the final round of survey, the Kendall′s coefficients of concordance at each level were all greater than 0.1. Through statistical testing, the P-values were all less than 0.05, indicating good coordination of expert opinions. Ultimately, we established an operational biosafety evaluation system for major emergency public health events in medical institutions, consisting of 4 primary indicators, 26 secondary indicators, and 119 tertiary indicators, with additional deduction items, bonus items, unacceptable items, and monitoring indicators.Conclusions:Based on scientific theory, a biosafety evaluation system for major emergency public health events in medical institutions was constructed, achieving the integration of routine and emergency measures. This system can be used for self-assessment of laboratory biosafety during emergency public health events, addressing the lack of unified standards in biosafety evaluation. Through regular self-assessment, it can enhance the level of biosafety management in medical institution laboratories, to realize the value of application and dissemination.
