Objective To construct a model combining with traditional Chinese medicine(TCM)syndrome for predicting the risk of disease progression in patients with idiopathic membranous nephropathy(IMN)by machine learning methods,thus to quantitatively evaluating the value of TCM syndrome in the prediction of the risk of disease progression in IMN.Methods Monofactor analysis,recursive feature elimination(RFE)and multivariate binary Logistic regression analysis were used to screen the independent related factors affecting the risk of disease progression of IMN,and then a risk prediction model was constructed.A total of 102 patients with IMN were randomly assigned to the training set and the test set in a ratio of 65∶35,and then the comparison was conducted in the performance indicators of accuracy,sensitivity,specificity,F1 value,and area under the receiver operating characteristic(ROC)area under the curve(AUC)of the risk prediction model with or without the inclusion of the TCM syndrome information.Results Before the inclusion of TCM syndrome information,12 clinical characteristic variables for patients with MN were obtained after monofactor analysis combined with RFE screening,and they were age,hemoglobin quantification,urinary occult blood,24-hour urine protein quantification,urine protein-creatinine ratio,estimated glomerular filtration rate(eGFR),creatinine,uric acid,alanine transaminase,anti-phospholipase A2 receptor antibody(PLA2R-Ab),total cholesterol,and low-density lipoprotein cholesterd.A risk cholesterol prediction model containing the above variables was constructed.The multivariate binary Logistic regression analysis showed that the differences of the clinical variables mentioned above between the training-set group and test-set group were statistically significant,and the risk prediction model presented good sensitivity and predictability.Monofactor analysis combined with RFE screening was performed again after the inclusion of TCM syndrome information,and then 14 variables were obtained,which included blood stasis syndrome and dampness obstruction syndrome.The sensitivity and specificity of the model with the inclusion of the TCM syndrome information were significantly improved when compared with those without the inclusion of TCM syndrome information.Conclusion The results of the study initially indicate that TCM syndrome can be used as an important supplementary variable for predicting the risk of disease progression in IMN,and will provide a reference for intelligent diagnosis through the integration of traditional Chinese and western medicine information,and will supply the guidance for the treatment of IMN with TCM.

Objective To analyze the effect of modified sitting Baduanjin based on the theory of"moving to generate Yang"in promoting the recovery of patients after lung cancer surgery.Methods A total of 92 patients with lung cancer who were admitted to Haian Traditional Chinese Medicine Hospital between January 2022 and December 2024 were enrolled in this prospective study.The patients were assigned to control group(n=46,conventional nursing)or observation group(n=46,conventional nursing and modified sitting Baduanjin based on the theory of"moving to generate Yang")using random number table method.After one month of intervention,the incidence of complications was recorded.Chinese version of Anderson Symptom Assessment Scale(MDASI-C)and Perioperative Lung Symptom Scale(PSA-Lung)were used to assess the severity of symptoms.Pulmonary function indexes(forced expiratory volume in first second[FEV1],FEV1/FVC[forced vital capacity]),diaphragm thickness(DTei),peripheral blood indexes(interleukin[IL]-6,IL-8,vascular endothelial growth factor[VEGF],Apelin levels),quality of life(assessed by SF-36 questionnaire and Lung Cancer Therapeutic Function Assessment Scale[FACT-L])and metabolomic changes before and after intervention were analyzed.Results After intervention,MDASI-C score,PSA-Lung score,IL-6,IL-8,VEGF,and Apelin levels were decreased in both groups,while SF-36 score,FACT-L score,FVC,and FEV1/FVC were increased;the changes of these indexes were greater in the observation group as compared with the control group(P<0.05).There was no significant difference in the DTei between the two groups(P>0.05).Liquid Chromatogram-mass spectrometry showed that after intervention,α-glucose,creatinine and alanine increased,while alanine/glutamine,glycerol,threonine,isoleucine,low density lipoprotein,3-hydroxybutyric acid,very low density lipoprotein,and cholesterol decreased in both groups;the changes of these indexes were greater than those in the control group(P<0.05).The total incidence of adverse reactions in observation group was lower than that in control group(8.70%vs.26.09%,P<0.05).Conclusion The modified sitting Baduanjin based on the theory of"moving to generate Yang"can promote the alleviation of symptoms in patients with lung cancer after surgery,reduce the levels of IL-6,IL-8,VEGF and Apelin in peripheral blood,enhance metabolomics and lung function,improve quality of life,and is associated with a lower incidence of adverse reactions.

Objective:To explore the relevant factors affecting the accuracy of scanning glucose monitoring (FGM) technology in critically ill patients.Methods:A total of 53 patients who were admitted to the Intensive Care Unit (ICU) of the Second Affiliated Hospital of Soochow University and used FGM glucose monitoring from September 2022 to December 2023 were selected by means of a convenience sampling method. The paired data of arterial blood glucose and FGM glucose were analysed. The accuracy of FGM blood glucose measurement in critically ill patients was evaluated using Bland-Altman analysis. The blood glucose data were divided into two groups: the FGM monitoring accuracy group and the FGM monitoring non-accuracy group.. The t-test and χ2 test were used for the comparison of one-way analysis of arterial versus FGM accuracy among critically ill patients with different demographic characteristics. Logistic regression analysis was used to analyze the factors influencing the accuracy of FGM. Results:The results of Bland-Altman analysis of the 53 patients indicated that the mean bias value of FGM blood glucose was elevated at 1.215 mmol/L in comparison with arterial-blood gas analysis blood glucose values. An incidence of exceeding the upper and lower limits of the range was observed, amounting to 6.349%. The discrepancy between the studies was found to be statistically significant (95% CI:1.0394~1.3908, P<0.001). The effects of the changes in height ( OR=0.877, 95% CI:0.780~0.987, P=0.029), changes in leukocyte counts( OR=0.917, 95% CI:0.868~0.969, P=0.002), changes in C-reactive protein( OR=1.009, 95% CI:1.002~1.017, P=0.016), changes in albumin counts( OR=0.986, 95% CI:0.974~0.999, P=0.031), and whether or not sepsis ( OR=3.937, 95% CI:1.192~13.008, P=0.025) on the accuracy of FGM had a statistically significant. Conclusion:The mean bias value of the accuracy of FGM was relatively higher compared with that of arterial blood gas analysis blood glucose values, and the influencing factors involved height, white blood cells, C-reactive protein, albumin, and whether or not sepsis was present. With the development of science and technology, applying the FGM system to critically ill patients has an absolute advantage in determining the overall glycemic trend, and the application value of FGM technology deserves further study.

Objective:To explore the application of contrast-enhanced ultrasound in the preoperative evaluation of carotid body tumor (CBT).Methods:The clinical data of 13 CBT patients undergoing contrast enhanced ultrasound test and surgical treatment at Peking Union Medical College Hospital from Nov 2017 to Aug 2021 was retrospectively analyzed.Results:Among the 13 patients, 7 patients had bilateral lesions. 18 tumors were identified by contrast enhanced ultrasound, which showed rich blood supply, with marked enhancement in 13 tumors and moderate enhancement in 5 tumors. The origins of the arterial supply for tumors were identified by contrast enhanced ultrasound. Time-intensity curve analysis showed that the tumors had enhancement characteristics of fast wash in and slow wash out. The mean contrast wash in time was (3.33±1.40) s, the mean peak intensity was (10.41±1.74) dB, and the mean wash out time was (56.47±22.28) s. A total of 13 cases underwent successful surgical removal. Five cases of external carotid artery ligation and 2 cases of internal carotid artery reconstruction were performed during surgery. Postoperative transient neurological injury occurred in 5 cases. There were no cases of cerebral infarction or death in the perioperative period. Mean postoperative follow-up was 14.31 months. Five cases of neurological injury had satisfactory recovery and no other adverse events occurred.Conclusions:Contrast enhanced ultrasound is an effective method of preoperative imaging assessment for CBT, which helps the surgical planning and preoperative preparation.

Background and purpose:Next generation sequencing-identified genetic alterations of diffuse large B cell lymphoma(DLBCL)and baseline SUVmax detected by 18F-FDG PET/CT were correlated with patients'prognosis.However,their relationship and the associations with R-CHOP response of DLBCL are still unclear.This study aimed to analyze the association bewteen genetic alterations and 18F-FDG PET/CT SUVmax and their correlations with clinicopathological characteristics and R-CHOP response of DLBCL.Methods:A total of 225 cases of primary DLBCL detected by next generation sequencing using 481 lymphoma gene panel and examined by 18F-FDG PET/CT before treatment between 2022 and 2023 were collected.This study was approved by the Ethics Committee of Fudan University Shanghai Cancer Center(Ethical No.:050432-4-2307E)and acquired the informed consent of the patients.The translocations of BCL2,BCL6 and MYC were identified by fluorescence in situ hybridization.The clinicopathological characteristics and the PET/CT scan after R-CHOP chemotherapy were collected.Results:Finally,191 patients were enrolled in this study.The frequency of MYD88 mutation,TP53 mutation,copy number variations of CDKN2A/2B,CD79B mutation in the 191 DLBCL patients were 24.6%,27.2%,32.5%and 16.8%,respectively.The range of baseline SUVmax was 5.10-63.10(24.44±10.70,median 22.80).The baseline SUVmax of MYD88L265P DLBCL was significantly higher than that of MYD88 wild type(P=0.039).There were no significant associations of SUVmax with other gene alterations including TP53 mutation,CDKN2A/B loss,CD79B mutation,KMT2D mutation,TNFAIP3 mutation,B2M mutation,EZH2 mutation,BTG1/2 mutation,CREBBP mutation,gene translocations of MYC,BCL2 and BCL6.The higher SUVmax before treatment was correlated with higher serum lactate dehydrogenase(LDH)level(P=0.012)and non-germinal center B-cell-like(non-GCB)DLBCL(P=0.040).However,there was no significant association of SUVmax with R-CHOP response(P=0.714).TP53 mutation was significantly associated with the poor response of R-CHOP(P=0.001)and was an independent predictor of non-complete metabolic response(non-CMR).TP53 mutation combined with Ann Arbor stage,International Prognostic Index(IPI)score and serum LDH level could better predict R-CHOP response than each factor alone.Conclusion:MYD88L265P DLBCL had higher baseline 18F-FDG PET/CT SUVmax.The baseline SUVmax was not associated with R-CHOP response.However,TP53 mutation was significantly correlated with poor response of R-CHOP in DLBCL patients.TP53 mutation combined with clinicopathological characteristics could better predict R-CHOP response.The associations of gene alterations and SUVmax with prognosis of DLBCL patients needed to be explored in the future.

Objective To evalutate changes in laboratory indicators and clinical efficacy of roxadustat(Rox)in treating anemia patients after advanced kidney transplantation.Methods A retrospective analysis of 101 patients with anemia after kidney transplantation admitted to the Center of Kidney Diseases and Hemodialysis of Shaanxi Provincial People's Hospital from March 2020 to March 2023 was performed.Among them 48 cases were treated with roxadustat(Rox group)and 53 cases were treated with recombinant human erythropoietin(rhEPO)(rhEPO group).Both groups were treated with polyferose,methycobal and folic acid.The change of red blood cell(RBC),hemoglobin(Hb),erythropoietin(EPO),serum ferrin(SF),transferrin saturation(TSAT),and hepcidin(HePc),tacrolimus trough concentration(Tac CO),cyclosporine A trough concentration(CsA CO),mycophenolic acid area under curve(MPA-AUC),lymphocyte(Lym),T lymphocyte subgroup Th/Ts ratio(Th/Ts),serum creatinine(Scr)and blood urea nitrogen(BUN)were observed in the 1st,3rd and 6th month after treatment respectively.The incidence of side effect induce by medicine during 6 months between the two groups were analysed.Results Before the beginning treatment,there was no significant difference in RBC,Hb,EPO,SF,TSAT,HePc,Tac CO,CsA CO,MPA-AUC,Lym,Th/Ts,Scr and BUN between the two groups and the differences were not statistisally significant(t=-0.319～2.024,all P＞0.05).After the 1st,3rd and 6th month of treatment,the RBC,Hb,EPO,SF,TSAT of the two groups of patients were increased compared to before treatment,while HePc was decreased compared to before treatment,and there were significant differences within the groups(F=234.890,219.907;256.171,201.231;138.023,89.247;92.89,215.780;189.198,179.092;112.132,76.127,all P＜0.05).The RBC,Hb and SF levels in the Rox group were higher than those in the rhEPO group(F=9.672,8.165,139.360),while EPO and HePc levels were lower than those in the rhEPO group(F=124.437,78.147),and the differences were significant(all P＜0.05).There was no significant difference in TSAT between the two groups(F=7.118,P=0.119).Tac CO,CsA CO,MPA-AUC,Lym,Th/Ts showed no significant changes between groups compared to before treatment,the Scr and BUN showed a slight increase compared to before treatment,but there were no statistically significant differences in intra group and between two groups comparisons(F=0.665,1.167,1.097,1.343,5.219,0.696,1.106,all P＞0.05).There was no statistically significant difference in the incidence of adverse reactions between the two groups(x2=0.083,P=0.773).Conclusion Roxadustat has better clinical efficacy in the treatment of patients with anemia after kidney transplantation,which can effectively improve anemia and regulate iron metabolism in the body.There is no significant impact on the immune status of the transplant recipients,and the transplanted kidney function is stable and safe.

Objective: To explore the association of tobacco/alcohol-excessive Internet usage and insufficient sleep with depressive symptoms among middle school students, so as to provide a reference for improving mental health of middle school students. Methods: In accordance with the cluster random sampling method, a total of 18 484 middle school students in Shanghai were surveyed from September to November 2022. Tobacco/alcohol-excessive Internet usage and sleep duration with depressive symptoms were assessed using the relevant scale items included in the questionnaire of Surveillance for Common Disease and Health Risk Factors among Students. The χ 2 test was used for inter group comparison, Logistic regression analysis and likelihood ratio test were used to analyze the independent and aggregated associations of tobacco/alcohol-excessive Internet use and insufficient sleep wiht depressive symptoms. Results: Self reported rates of tobacco/alcohol-excessive Internet usage, insufficient sleep and depressive symptoms among adolescents were 14.7%, 73.5% and 16.3%, respectively. Tobacco/alcohol-excessive Internet usage ( OR=2.69, 95%CI =2.44-2.97) and insufficient sleep ( OR=1.76, 95%CI =1.58-1.95) were associated with depressive symptoms ( P <0.05). Compared to middle school students with no tobacco/alcohol-excessive Internet usage and sufficient sleep, those with both tobacco/alcohol-excessive Internet usage and insufficient sleep showed the higher rate of depressive symptoms ( OR=4.71, 95%CI =4.08-5.44, P <0.05). Further stratified analysis results showed that, compared to the boys and the high school students, the separate and joint association of tobacco/alcohol-excessive Internet usage and insufficient sleep with depressive symptoms were more pronounced in the girls and the middle school students [ OR (95% CI ) for tobacco/alcohol-excessive Internet usage were 3.09 (2.68-3.56) and 4.74 (3.86-5.83), respectively; OR (95% CI ) for insufficient sleep were 1.86 (1.60-2.17) and 2.00 (1.58-2.53), respectively; and the OR (95% CI ) for the joint association were 6.05 (5.01-7.31) and 9.15 (6.98-11.99), respectively, P <0.05]. Conclusions Tobacco/alcohol-excessive Internet usage and insufficient sleep are associated with depressive symptoms in middle school students. Prevention and control strategies for adolescent mental health should be developed with consideration of health related behaviors, and also need to be tailored by focusing on gender and grade differences.

With the improvement of people's living standards and the increasing aging population， the incidence of cardiovascular diseases has sharply risen， making it the leading cause of death and a major "killer" for humans. The prevention and treatment of cardiovascular diseases still face severe challenges. Shenmai injection （SMI）， a Chinese medicinal preparation， is widely used in the prevention and treatment of cardiovascular diseases because of its individualized advantages in syndrome differentiation and definite efficacy. Meanwhile， its pharmacological effects and related mechanism are becoming increasingly clear. Modern research shows that SMI can exert cardioprotective effects by reducing myocardial inflammatory response， alleviating oxidative stress， inhibiting myocardial cell apoptosis， improving microcirculatory dysfunction after myocardial ischemia-reperfusion， protecting mitochondrial structure and function， inhibiting ventricular remodeling， reducing drug-induced cardiotoxicity， and possessing antiviral properties. Additionally， it can produce cardiovascular protection by relaxing blood vessels， protecting endothelial cells， and promoting angiogenesis. Furthermore， SMI can lower blood viscosity and lipid levels， thus improving blood rheology. In the future， more clinical trials and basic research are needed to clarify its therapeutic efficacy and target mechanism to further confirm the effectiveness and safety of its clinical application.
