Acute myocardial infarction(AMI)is a common cardiovascular emergency in clinic.Early reperfusion is a typical and effective method for the treatment of AMI.However,the recovery of blood supply after reperfusion therapy will accelerate the damage of ischemic myocardium and cause myocardial ischemia-reperfusion injury(MI/RI).In recent years,studies have found that TCM has the unique advantages of multi-component,multi-channel and multi-target in the intervention of MI/RI.Janus tyrosine kinase/signal transducer and activator of transcription(JAK/STAT)signaling pathway is closely related to MI/RI,which can reduce MI/RI process by regulating inflammation,oxidative stress,cell proliferation,differentiation and apoptosis.This article reviewed the mechanism of JAK/STAT signaling pathway in MI/RI and the research of TCM targeting this pathway,in order to provide references for the prevention and treatment of MI/RI and further drug development.

Objective:To investigate the effect of microwave on human adenovirus type 2 (HAdV-2) capsid protein in simulated infectious wastes.Methods:Droplets of HAdV-2 virus suspension were added to medical disposable gloves to simulate infectious waste, irradiated under different microwave conditions, the temperature change was recorded, and the irradiated viral supernatant was treated with Dnase I and detected by PCR and qPCR to determine the effect of microwave on the integrity of the viral capsid. ELISA was used to detect the effect of microwave irradiation on the structure of viral hexon protein. The virus was treated alone at the highest temperature during microwave irradiation to investigate whether there were non-thermal effects during microwave disinfection.Results:The maximum temperature during microwave irradiation was 76 ℃, and the PCR and qPCR result showed that Dnase I could significantly damage the viral nucleic acid after microwave irradiation, while the virus control group and heat treatment group were not significantly affected, indicating that microwave irradiation could destroy the integrity of the viral capsid. The result of ELISA showed that microwave irradiation could significantly weaken the binding ability of Hexon protein and antibody, and the result of heat treatment group were similar.Conclusions:Microwave irradiation can destroy the integrity of the HAdV-2 capsid and the structure of Hexon protein, in which the damage to the integrity of the capsid is mainly due to non-thermal effects, and the structural changes of hexon protein are mainly due to thermal effects.

Malignant tumors have surpassed stroke and coronary heart disease to become the main cause of death before the age of 70 in the world. The incidence of malignant tumors is increasing year by year， which seriously affects the living standards and social and economic development of Chinese people. Surgery， radiotherapy， chemotherapy， targeted therapy， and immunotherapy are the main means of Western medicine to intervene in tumors， which are of great significance for prolonging the survival time of patients. However， there are many disadvantages such as adverse reactions and drug resistance. Traditional Chinese medicine has become a research hotspot in recent years because of its definite curative effect and wide application in tumor treatment. Xiao Chaihutang is derived from the Treatise on Febrile and Miscellaneous Diseases. It is composed of Bupleuri Radix， Scutellariae Radix， Ginseng Radix， Pinelliae Rhizoma， Glycyrrhizae Preparata Radix， Ginger， and Jujube. It has the effects of reconciling Shaoyang， reconciling cold and heat Yin and Yang， soothing the liver， and relieving depression. This prescription and the prescriptions based on it are widely used in various stages of tumors. This study summarized the Chinese and foreign research of Xiao Chaihutang in the field of tumors in the past 10 years and explored the role and mechanism of Xiao Chaihutang in blocking precancerous lesions， controlling the development of malignant tumors， reducing the occurrence of adverse reactions after intervention， and alleviating common complications， with a view to expanding the clinical medication ideas.

Objective To investigate the therapeutic effect and underlying mechanism of Qishishenshu Capsule on renal fibrosis in mice with early diabetic nephropathy(DN).Methods A DN mouse model was established by multiple injections of streptozotocin.The mice were randomly divided into a normal group(NC),model group(DN),and Qishi group(QS)(0.9 g/(kg·d)),with eight mice in each group.Mice were gavaged continuously for 4 weeks,and fasting blood glucose(FBG)was measured weekly.Four weeks later,urinary albumin/creatinine(UACR),serum creatinine,and blood urea nitrogen were measured.Hematoxylin-eosin,periodicacid-Schiff,and Sirius red staining were used to analyze renal pathological changes.Real-time fluorescence quantitative reverse-transcription polymerase chain reaction was used to detect the mRNA levels of fibronectin(FN),collagen type Ⅰ alpha 1(Col1a1),and α-smooth muscle actin(α-SMA).Immunohistochemistry and Western blot were performed to detect FN,collagen type Ⅰ(Collagen Ⅰ),collagen typeⅢ(Collagen Ⅲ),α-SMA,Podocin,Nephrin,and transforming growth factor-β1/SMAD family member2/3(TGF-β1/Smad2/3)pathway-related proteins.Results Compared with mice in the NC group,those in the DN group showed significantly higher levels of FBG and UACR(P＜0.001),and mesangial hyperplasia,basement membrane thickening,and collagen deposition in the renal tissue.The mRNA levels of FN,Col1a1,and α-SMA were increased(P＜0.05).Protein levels of Podocin and Nephrin were decreased(P＜0.05).The levels of FN,Collagen I,Collagen Ⅲ,α-SMA,and TGF-β1/Smad2/3 pathway proteins were increased(P＜0.05).Compared with the DN group,the QS group's level of UACR was decreased(P＜0.05),their renal pathological injury was alleviated,and mRNA levels of FN,Collagen Ⅰ,andα-SMA were attenuated(P＜0.05);whereas their protein levels of Podocin and Nephrin were elevated(P＜0.05).The levels of FN,Collagen Ⅰ,Collagen Ⅲ,α-SMA,and TGF-β1/Smad2/3 pathway proteins were also decreased(P＜0.05).Conclusions Qishishenshu Capsule improved renal fibrosis in DN mice,probably through the inhibition of the TGF-β1/Smad2/3 signaling pathway.

Objective : To analyze the expression and immune infiltration levels of the BMP7 gene ( BMP7) in e- sophageal squamous cell carcinoma(ESCC) ． Methods : Initially，in 274 cases of ESCC and 242 cases of normal tissues，the level of BMP7 was verified by immunohistochemistry ，and the relationship between the expression difference and the survival cycle and clinical pathological characteristics of patients with ESCC was explored，and BMP7 overexpression plasmid transfection of ESCC cells was established，and the effect of BMP7 on the biological behavior of ESCC cells was examined by CCK-8，Clone，and Transwell. Results : BMP7 expression in normal e- sophageal tissues was higher than that of ESCC(P＜0. 001) ，the expression level of BMP7 was correlated with the degree of differentiation of patients(P = 0. 006) and TNM staging(P ＜0. 001) ，and the survival of patients with high expression of BMP7 exceeded that of patients with low BMP7 (P = 0. 041) ，and the experiments of CCK-8 and Clone showed that the proliferation effect of cells in the overexpressed BMP7 group was lower than that of the control group．Transwell experiments confirmed that the cell invasion migration capacity of the overexpressed BMP7 group was less than that of the control one．The immune infiltration results showed that BMP7 was positively correlated with macrophages(P = 0. 008) and negatively correlated with γ-δT cells(P = 0. 028) ． Conclusion BMP7 is low in ESCC and associated with poor prognosis and immune infiltration levels in patients.

Objective:To study the inactivation effects of microwave on human adenovirus 2 (HAdV-2) in simulated infectied wastes, and to explore its molecular mechanism.Methods:25 μl of HAdV-2 virus suspension was dripped with medical disposable gloves, masks and cotton swabs to simulate infectied wastes, and irradiated under different microwave conditions: gloves and masks were irradiated for 30 s, 60 s, and 90 s at 300 W, 500 W, and 700 W, respectively. Cotton swabs irradiate 60 s, 90 s, 120 s at 500 W and 700 W respectively. Temperature changes were recorded, and the inactivation logarithmic values were calculated by the 50% endpoint method to evaluate the microwave inactivation effects, and the proliferation ability of the virus was detected by qPCR. The damage of Penton, Fiber, Hexon and E2 B genes was detected by PCR. The virus was treated with the highest temperature of 76 ℃ during microwave irradiation to study whether there was non-thermal effect during microwave disinfection. Results:After microwave irradiation of infectied waste, the temperature of masks and gloves carriers rises rapidly, with the highest temperature of 76 ℃. The temperature of the cotton swab carriers rose slowly, and the highest temperature is 65 ℃. The inactivation effect of microwave on HAdV-2 was positively correlated with microwave power and irradiation time. In the mask and glove group, microwave power of 700 W irradiated for 60 seconds, and the inactivation logarithm value could reach 3.0, In the cotton swab group, microwave power of 700 W irradiated for 120 seconds, and the inactivation logarithm value was still less than 3.0. This indicated that there were differences in the conditions for microwave inactivation of the virus in different carriers. The qPCR result showed that microwave irradiation could weak the proliferation ability of the virus. Microwave irradiation had no effect on the virus's Penton and Fiber genes, but caused some damage to the Hexon and E2 B genes. The inactivation effect of individual heat treatment on HAdV-2 was weaker than that of microwave irradiation, and there was no damage to the Hexon, Penton, Fiber, and E2 B genes. This indicated the presence of non thermal effects during the microwave inactivation process. Conclusions:Microwave irradiation can inactivate HAdV-2 in simulated infectied wastes through thermal and non-thermal effects, and its damage to viral DNA is one of the mechanisms of virus inactivation.

OBJECTIVE: To investigate the correlation between early-stage blood pressure indexes and prognosis in sepsis patients. METHODS: A retrospective cohort study was conducted on the medical records of patients diagnosed with sepsis from 2001 to 2012 in the Medical Information Mart for Intensive Care-III (MIMIC-III) database. Patients were divided into survival group and death group according to the 28-day prognosis. General data of patients and heart rate (HR) and blood pressure at admission to ICU and within 24 hours after admission were collected. The blood pressure indexes including the maximum, median and mean value of systolic index, diastolic index and mean arterial pressure (MAP) index were calculated. The data were randomly divided into training set and validation set (4 : 1). Univariate Logistic regression analysis was used to screen covariates, and multivariate Logistic stepwise regression models were further developed. Model 1 (including HR, blood pressure, and blood pressure index related variables with P < 0.1 and other variables with P < 0.05) and Model 2 (including HR, blood pressure, and blood pressure index related variables with P < 0.1) were developed respectively. The receiver operator characteristic curve (ROC curve), precision recall curve (PRC) and decision curve analysis (DCA) curve were used to evaluate the quality of the two models, and the influencing factors of the prognosis of sepsis patients were analyzed. Finally, nomogram model was developed according to the better model and effectiveness of it was evaluated. RESULTS: A total of 11 559 sepsis patients were included in the study, with 10 012 patients in the survival group and 1 547 patients in the death group. There were significant differences in age, survival time, Elixhauser comorbidity score and other 46 variables between the two groups (all P < 0.05). Thirty-seven variables were preliminarily screened by univariate Logistic regression analysis. After multivariate Logistic stepwise regression model screening, among the indicators related to HR, blood pressure and blood pressure index, the HR at admission to ICU [odds ratio (OR) = 0.992, 95% confidence interval (95%CI) was 0.988-0.997] and the maximum HR (OR = 1.006, 95%CI was 1.001-1.011), maximum MAP index (OR = 1.620, 95%CI was 1.244-2.126), mean diastolic index (OR = 0.283, 95%CI was 0.091-0.856), median systolic index (OR = 2.149, 95%CI was 0.805-4.461), median diastolic index (OR = 3.986, 95%CI was 1.376-11.758) were selected (all P < 0.1). There were 14 other variables with P < 0.05, including age, Elixhauser comorbidity score, continuous renal replacement therapy (CRRT), use of ventilator, sedation and analgesia, norepinephrine, norepinephrine, highest serum creatinine (SCr), maximum blood urea nitrogen (BUN), highest prothrombin time (PT), highest activated partial thromboplastin time (APTT), lowest platelet count (PLT), highest white blood cell count (WBC), minimum hemoglobin (Hb). The ROC curve showed that the area under the curve (AUC) of Model 1 and Model 2 were 0.769 and 0.637, respectively, indicating that model 1 had higher prediction accuracy. The PRC curve showed that the AUC of Model 1 and Model 2 were 0.381 and 0.240, respectively, indicating that Model 1 had a better effect. The DCA curve showed that when the threshold was 0-0.8 (the probability of death was 0-80%), the net benefit rate of Model 1 was higher than that of Model 2. The calibration curve showed that the prediction effect of the nomogram model developed according to Model 1 was in good agreement with the actual outcome. The Bootstrap verification results showed that the nomogram model was consistent with the above results and had good prediction effects. CONCLUSIONS The nomogram model constructed has good prediction effects on the 28-day prognosis in sepsis patients, and the blood pressure indexes are important predictors in the model.

Myocardial infarction （MI） is a common cardiovascular disease in clinical practice and one of the main causes of cardiovascular mortality. Its pathogenesis is complex and associated with oxidative stress reactions. Nuclear factor E₂-related factor 2 （Nrf2） is a key factor in regulating oxidative stress reactions. It can regulate the expression of heme oxygenase-1 （HO-1）， playing a role in maintaining the oxidative-reductive homeostasis in the body. During the course of MI， the biological activity and levels of Nrf2 and HO-1 decrease， leading to weakened tissue antioxidant and anti-inflammatory capabilities， endothelial damage in myocardial blood vessels， release of vascular cell adhesion factors， and impaired endothelial function. In recent years， many basic research studies have explored the role and mechanisms of traditional Chinese medicine （TCM） in treating MI by modulating the Nrf2/HO-1 signaling pathway. The results have indicated that the Nrf2/HO-1 signaling pathway is an important potential target for TCM in the treatment of MI. This article reviewed the mechanism of the Nrf2/HO-1 signaling pathway in MI and the research progress of TCM in targeting and regulating this pathway， aiming to provide a theoretical basis for the prevention and treatment of MI and further drug development.
