Recent studies have shown that Gal-9 is highly expressed in the liver and can help to maintain intrahepatic immune homeostasis and perform biological functions in various liver diseases. This article reviews the immunomodulatory functions of Gal-9 and its role in different liver diseases. Studies have shown that Gal-9 has important biological functions in different liver diseases through multiple pathways. Research on the specific immunomodulatory mechanisms and functions of Gal-9 may help to discover the therapeutic role of Gal-9 in liver diseases.

Objective To investigate the clinical efficacy of modified Fuzheng Yiliu Decoction(composed of Astragali Radix,Codonopsis Radix,Ligustri Lucidi Fructus,Hedyotis Diffusae Herba,Moutan Cortex,Visci Herba,etc.)combined with XELOX regimen(Oxaliplatin plus Capecitabine)for the treatment of postoperative patients with advanced gastric cancer of qi and yin deficiency type.Methods A total of 80 postoperative patients with advanced gastric cancer of qi and yin deficiency type were randomly divided into the Chinese medicine group and the control group,with 40 cases in each group.Both groups received chemotherapy with XELOX regimen,while the Chinese medicine group was given modified Fuzheng Yiliu Decoction.Three weeks constituted a course of treatment,the medication of Chinese medicine decoction lasted for two weeks or more in each course of treatment,and a total of 8 courses of treatment were performed.The incidence of adverse reactions during chemotherapy was monitored and changes in serum tumor markers of serum carcinoembryonic antigen(CEA),carbohydrate antigen 199(CA199)and alpha-fetoprotein(AFP)were observed in the two groups before and after treatment.Moreover,the patients'quality of life was assessed by the scores of Karnofsky's Performance Status(KPS)and World Health Organization Quality of Life Measurement Scale(WHOQOL-100).Long-term follow-up was carried out for the evaluation of the prognostic indicators such as overall survival and one-year and 2-year overall survival rates.Results(1)Patients in the two groups were all followed up,and the median follow-up time was 27 months(95%CI:23.59-27.86).(2)After treatment,the levels of serum CEA and AFP in the Chinese medicine group were significantly lower than those before treatment(P＜0.05 or P＜0.01),while serum CA199 tended to decrease compared with those before treatment,but the difference was not statistically significant(P＞0.05);in the control group,the levels of serum CEA,CA199,and AFP were not significantly decreased after treatment(P＞0.05).The intergroup comparison showed that the decrease of serum CEA,CA199 and AFP levels in the Chinese medicine group was significantly superior to that in the control group(P＜0.05 or P＜0.01).(3)The adverse reactions during chemotherapy in the two groups mainly involved bone marrow suppression,gastrointestinal reactions and liver function abnormalities,etc.The incidences of all adverse reactions in the Chinese medicine group tended to be lower than those in the control group,but the differences were not statistically significant(P＞0.05).(4)After treatment,the KPS scores of patients in both groups were improved compared with those before treatment(P＜0.01),and the improvement in the Chinese medicine group was significantly superior to that in the control group(P＜0.01).(5)After treatment,the scores of the four dimensions of WHOQOL-100 such as health status,mobility,life feelings,and other activities of daily life in the Chinese medicine group were significantly improved compared with the pre-treatment(P＜0.05),whereas there was no significant improvement in the control group(P＞0.05).The intergroup comparison showed that the improvement of the scores of each dimension of the WHOQOL-100 in the Chinese medicine group was significantly superior to that in the control group(P＜0.05 or P＜0.01).(6)The median survival in the Chinese medicine group was 29.0 months(95%CI:25.95-31.70)and that in the control group was 22.0 months(95%CI:19.67-25.58),indicating that the median survival was significantly prolonged in Chinese medicine group(P＜0.01).The one-year and 2-year postoperative survival rates were 97.5%and 77.5%in the Chinese medicine group and 92.5%and 47.5%in the control group,respectively.The intergroup comparison showed that the one-year and 2-year postoperative survival rates in the Chinese medicine group were higher than those in the control group(P＜0.01).Conclusion Modified Fuzheng Yiliu Decoction can effectively alleviate the adverse reactions during adjuvant chemotherapy for postoperative patients with advanced gastric cancer of qi and yin deficiency type,improve the quality of life of patients,and prolong the survival time of patients.

Objective To compare the influence between self-monitoring of blood gluocose(SMBG)combined with digital diabetes management and traditional management mode on the related clinical indexes in the patients with type 2 diabetes mellitus(T2DM).Methods A total of 100 patients with T2DM treated in the endocrinology and metabolism outpatient department of this hospital from January 2022 to June 2022 and meeting the inclusion criteria of this study were successively included.They were divided into the experimental group and control group.The experimental group was managed by SMBG combined with digital diabetes man-agement mode,while the control group adopted the traditional management mode,the outpatient clinic follow up once a month.After 6 months of follow-up,fasting blood glucose,glycosylated hemoglobin(HbA1c),low density lipoprotein cholesterol(LDL-C)and urinary microalbumin/creatinine ratio(UACR)were compared between the two groups.Results The FBG,HbA1c,LDL-C,and UACR of the experimental group decreased after intervention when compared with baseline.Compared with the control group,the FBG[8.7(7.7,9.2)mmol/L vs.10.8(8.8,12.7)mmol/L,Z=-4.660,P＜0.001],HbA1c[6.3％(5.3,7.8)％vs.8.5％(7.2,10.0)％,Z=-5.130,P＜0.001],LDL-C[2.6(1.8,3.1)mmol/L vs.3.3(2.6,4.0)mmol/L,Z=-4.112,P＜0.001],UACR[16.1(3.5,46.5)mg/g vs.58.4(11.9,108.0)mg/g,Z=-2.220,P=0.026]for patients in the expriemental group after intervention were significantly decreased.Conclusion SMBG combined with digital diabetes management model can significantly improve the clinical indicators of patients.

Objective To investigate the changes of macular microcirculation and aqueous humor cytokine expression in patients with diabetic macular edema(DME)after anti-vascular endothelial growth factor(VEGF)treatment,and analyze the relationship with efficacy.Methods A total of 62 patients(91 eyes)with DME who were treated in the First Hospital of Nanchang from October 2021 to August 2023 were selected and treated with intravitreal injection of conbercept.According to the reduction of central macular thickness(CMT),they were divided into efficacy significant group(CMT reduction≥100μm,59 eyes)and non-efficacy significant group(CMT reduction＜100μm or increase,32 eyes).The changes of CMT,vessel density(VD)of superficial capillary plexus(SCP),fovea avascular area(FAZ),VEGF,interleuki(IL)-6,IL-8,and IL-10 after anti-VEGF treatment were analyzed.Receiver operating characteristic(ROC)curve was used to evaluate the predictive value of each index.Results Before treatment,the levels of VEGF and IL-10 in aqueous humor in efficacy significant group were significantly higher than those in non-efficacy significant group,and the level of IL-8 was significantly lower than that in non-efficacy significant group(P＜0.05).After treatment,levels of VEGF,IL-6,IL-8 and IL-10 in aqueous humor in both groups were significantly lower than before treatment(P＜0.05).The levels of VEGF,IL-6 and IL-8 in aqueous humor in efficacy significant group were significantly lower than those in non-efficacy significant group,and the level of IL-10 was significantly higher than that in non-efficacy significant group(P＜0.05).Before and after anti-VEGF treatment,there were no significant changes in FAZ area and SCP-VD in both groups(P＞0.05).Correlation analysis showed that VEGF(r=0.571,P＜0.001)and IL-10(r=0.382,P=0.008)in aqueous humor at baseline were positively correlated with CMT reduction,IL-8 was negatively correlated with CMT reduction(r=-0.689,P＜0.001).IL-6,FAZ area and SCP-VD were not correlated with CMT reduction(P＞0.05).Cytokine levels were not correlated with FAZ area and SCP-VD(P＞0.05).ROC curve results showed that area under the curve of IL-8,VEGF and IL-10 at baseline predicting anti-VEGF efficacy were 0.825,0.813 and 0.676,respectively.Conclusion The levels of VEGF,IL-8,and IL-10 in aqueous humor at baseline in DME patients were correlated with anti-VEGF efficacy and could predict the efficacy of anti-VEGF.

Objective To explore and compare the clinical efficacy of orthopedic robot assisted femoral neck system(FNS)and traditional manual FNS in the treatment of femoral neck fractures in middle-aged and young people.Methods The clinical data of 62 consecutive patients with femoral neck fracture and age less than 65 years old admitted to the Intelligent Or-thopaedic Department of Beijing Jishuitan Hospital from June 2021 to June 2022 were retrospectively analyzed.According to whether orthopedic robot-assisted surgery the patients were divided into two groups:30 patients aged 34 to 56 years old were treated with orthopedic robot assisted FNS internal fixation after closed or limited open reduction(experimental group);32 pa-tients aged 33 to 54 years old underwent FNS internal fixation after closed or limited open reduction(control group).The age,gender,time from injury to admission,average hospital stay,surgical duration,intraoperative bleeding volume,and intraopera-tive fluoroscopy frequency of two groups of patients were analyzed and compared.The hip joint function in both groups of pa-tients was evaluated using the Harris hip joint scoring standard at 6 months after surgery.Results All 62 patients with femoral neck fractures successfully completed the surgery.There was no significant difference(P＞0.05)between the experimental group and the control group in terms of baseline data such as age,gender,time from injury to admission,time from admission to surgery and the intraoperative bleeding.The surgical duration of the experimental group was significantly shorter than that of the control group[42.1(28.5,50.7)min vs.53.4(36.9,62.5)min,Z=-2.338,P=0.019].The intraoperative X-ray fluoroscopy frequency of the experimental group was significantly lower than that of the control group[8.0(6.0,11.0)times vs.15.0(13.0,17.0)times,Z=-5.960,P＜0.001].In terms of postoperative hip joint function,there was no significant difference in Harris score between the two groups of patients at 6-month follow-up(P＞0.05).Conclusion Compared with manual operation of FNS,orthopedic robot assisted FNS in the treatment of femoral neck fractures can help shorten surgical time,reduce intraop-erative fluoroscopy frequency,and have similar therapeutic effects on long-term hip joint function recovery.

Objective To investigate the clinical characteristics of female migraine patients with patent foramen ovale(PFO)and design a risk prediction model for PFO in female migraine patients(migraineur patients PFO risk prediction model,MPRPM).Methods Female migraine patients who visited Zhongshan Hospital,Fudan University from Jun 1,2019 to Dec 31,2022 were included.Preoperative information and follow-up results after discontinuation of medication were collected.Patients were divided into PFO-positive and PFO-negative groups based on transesophageal echocardiography results.A multivariate Logistic regression model and a random forest model were constructed,and the random forest model was validated multidimensionally.Key features were selected based on the mean decrease accuracy(MDA)to construct MPRPM.Results A total of 305 female patients were included in the study,with 204 patients in the PFO-positive group and 101 patients in the PFO-negative group.Multivariate Logistic regression analysis showed that age at migraine onset,attack frequency,severe impact on life during attacks,exercise-related headaches,menstruation-induced headaches,aura migraines,and a history of cryptogenic stroke were predictive factors for PFO positivity.The random forest model effectively predicted the incidence of PFO in female migraine patients,with an AUC of 0.895(95%CI:0.847-0.943).MPRPM demonstrated a sensitivity of 71.6%and specificity of 91.1%(AUC:0.862,95%CI:0.818-0.906,P<0.001).The optimal cut-off value was 2.5 points.Patients correctly classified by the model showed a higher rate of symptom improvement compared to incorrectly classified patients(94.3%vs.82.0%,P=0.023).Conclusion We identified predictive factors for PFO in migraine patients.MPRPM can provide guidance in the diagnostic process and therapeutic decision-making for female migraine patients,assist in patient triage,and reduce the healthcare burden.

Objective To investigate the associations of reproductive health indicators with lung function and chronic obstructive pulmonary disease(COPD)among women aged 40 years and above.Methods From Jul to Sep,2021,female subjects aged 40 years and above were randomly selected from the Shanghai Suburban Adult Cohort and Biobank for COPD screening.A questionnaire was used to obtain information on demographic characteristics and reproductive health indicators.Linear regression was used to analyze the effects of reproductive health indicators on forced vital capacity(FVC)and forced expiratory volume in the first second(FEV1).Logistic regression was also used to analyze the effects of reproductive health factors on FVC as a percentage of the predicted value(FVC%Pred)and FEV1%Pred as well as on COPD.Results A total of 1876 women aged 40 years and above were enrolled with mean age of(62.1±8.2)years old,among them,78.1%were menopausal,and 40.9%had been pregnant≥3 times.Multivariate analysis showed that FVC and FEV1 decreased in postmenopausal women,but menopause was not associated with a decrease in their percentage of predicted values.Pregnancies≥3 times was a risk factor for COPD(for 3 times,OR=4.92,95%CI:1.48-19.95,P<0.05;for≥4 times,OR=9.06,95%CI:2.32-41.57,P<0.01),while pregnancies of 2 times did not increase the risk of COPD.Conclusion In women aged 40 years and above,menopause is associated with poorer FVC and FEV1,and excessive pregnancy(≥3 times)is a risk factor for COPD.

Lung cancer has the highest morbidity and mortality in China.Guiding by Chinese medical master ZHOU Dai-Han and based on the experience of diagnosis and treatment of lung cancer in the past 40 years,the authors believe that phlegm is the key to the pathogenesis of lung cancer,and then put forward the phlegm-toxin pathogenesis theory according to the clinical characteristics of lung cancer.Lung cancer is a disease of deficiency in origin and excess in superficiality.Qi deficiency of lung and spleen leads to the formation of phlegm-toxin,and phlegm-toxin is the key pathogenic factor for the development and progression of lung cancer.Based on the phlegm-toxin pathogenesis,the treatment of lung cancer with the method of replenishing qi and removing phlegm(abbreviated as Yiqi Chutan method)is proposed.The clinical practice of the research team in recent years has shown that Yiqi Chutan method is effective in the treatment of middle-to-advanced lung cancer,in particular the middle-to-advanced lung cancer in the elderly,which can prolong the survival time of patients with advanced lung cancer,improve the quality of life of lung cancer patients,relieve lung cancer related symptoms,enhance the efficacy and reduce the toxicity of anti-tumor treatment,and prevent and treat early lung cancer.The study on the anti-tumor mechanism of Yiqi Chutan method showed that the anti-tumor mechanism of Yiqi Chutan Formula was related to the inhibition metastasis of lung cancer,regulation of cell cycle,inhibition of epithelial-mesenchymal transition,regulation of the apoptosis and autophagy of cells,and improvement of the EGFR-TKIs resistance.

Pharmacokinetics of traditional Chinese medicine(TCM)is a discipline that adopts pharmacokinetic research methods and techniques under the guidance of TCM theories to elucidate the dynamic changes in the absorption,distribution,metabolism and excretion of active ingredients,active sites,single-flavour Chinese medicinal and compounded formulas of TCM in vivo.However,the sources and components of TCM are complex,and the pharmacodynamic substances and mechanisms of action of the majority of TCM are not yet clear,so the pharmacokinetic study of TCM is later than that of chemical medicines,and is far more complex than that of chemical medicines,and its development also confronts with challenges.The pharmacokinetic study of TCM originated in the 1950s and has experienced more than 70 years of development from the initial in vivo study of a single active ingredient,to the pharmacokinetic and pharmacodynamic study of active ingredients,to the pharmacokinetic study of compound and multi-component of Chinese medicine.In recent years,with the help of advanced extraction,separation and analysis technologies,gene-editing animals and cell models,multi-omics technologies,protein purification and structure analysis technologies,and artificial intelligence,etc.,the pharmacokinetics of TCM has been substantially applied in revealing and elucidating the pharmacodynamic substances and mechanisms of action of Chinese medicines,research and development of new drugs of TCM,scientific and technological upgrading of large varieties of Chinese patent medicines,as well as guiding the rational use of medicines in clinics.Pharmacokinetic studies of TCM have made remarkable breakthroughs and significant development in theory,methodology,technology and application.In this paper,the history of the development of pharmacokinetics of TCM and the progress of cutting-edge research was reviewed,with the aim of providing ideas and references for the pharmacokinetics of TCM and related research.
