Tripterygium wilfordii polyglycosides are one of the most commonly used Tripterygium wilfordii preparations, which have anti-inflammatory and immune-regulating effects. Their unique therapeutic effect on some autoimmune diseases and kidney diseases is almost irreplaceable by other similar drugs, but the possible reproductive damage is the bottleneck that hinders their clinical application. In clinical use, female patients often suffer from menstrual cycle disorders, decreased menstrual flow, even amenorrhea, infertility, and other symptoms, and the main toxic mechanism lies in damaging the reproductive and endocrine functions of the ovary and inhibiting the growth and development of follicles. Therefore, it is particularly necessary to understand the toxic and side effects of Tripterygium wilfordii polyglycosides on female reproduction and master the detoxification methods during clinical use. However, there is no clear solution to these problems. According to the theory of traditional Chinese medicine, "kidney governs reproduction", and the relationship between kidney Yin, kidney essence, and female ovum is close. Therefore, by considering that the damage to the reproductive system caused by Tripterygium wilfordii polyglycosides belongs to the category of kidney deficiency, Yin damage, and essence deficiency, the "strengthening kidney Yin" method is proposed. It points out that the reproductive toxicity damage of Tripterygium wilfordii polyglycosides on the female can be effectively alleviated by tonifying kidney and Yin essence in clinical use. The relevant research on traditional Chinese medicine, classical prescription, test prescription, and acupuncture is summarized to verify the necessity of the "strengthening kidney Yin" method, so as to provide a theoretical basis for the safe and rational clinical use of Tripterygium wilfordii.

Objective We aimed to investigate the relationship between microscopic pattern of blood stasis and renal pathological grade and related physical and chemical indexes in children with Henoch-Sch?nlein purpura nephritis(HSPN).Methods We conducted a retrospective analysis of 800 HSPN children from the medical records of the First Affiliated Hospital of Henan University of Chinese Medicine.Laboratory indicators(blood routine test,urine routine test,coagulation test,liver function)and renal pathological indicators of them were collected.According to the severity of renal pathological microscopic lesions,the microscopic pattern of blood stasis was divided into three types,including choroidal discord,dead blood coagulation and intracarenal disease accumulation.The classification of renal microscopic pattern of blood stasis and the correlation between laboratory indexes and renal pathological index were analyzed by Spearman grade correlation and binary Logistic regression analysis.Results(ⅰ)There was no statistical difference of the distribution of the renal microscopic pattern of blood stasis in the different traditional Chinese medicine patterns.(ⅱ)There were significant differences in the contents or the grade of albumin and fibrinogen in the HSPN children with different microscopic pattern of blood stasis(all P<0.05).(ⅲ)The maximum area under the receiver operating characteristic(ROC)curve between fibrinogen and intracarenal disease accumulation was 0.594(95%CI from 0.540 to 0.633,P<0.001);sensitivity was 0.447,specificity was 0.725;the best threshold on the ROC curve of 0.172 was 3.755 g/L.(ⅳ)There were positive correlations between the content of fibrinogen,ISKDC grade and Bohle A grade respectively with the scores of intracarenal disease accumulation type(r=0.176,r=0.315,r=0.656;all P<0.001).(ⅴ)There were positive correlations between the content of fibrinogen,ISKDC grade and Bohle A grade respectively with the renal microscopic pattern of blood stasis(r=0.157,r=0.377,r=0.429;all P<0.001).Conclusion The microscopic renal pattern of blood stasis can not only reflect the severity of renal blood stasis,but also reflect the severity and long-term prognosis of renal diseases.Albumin and urinary protein grade can reflect the early stage of the microscopic renal pattern of the blood stasis(choroidal discord).The content of fibrinogen increases with the aggravation of renal microscopic pattern of blood stasis,reflecting the end-stage of HSPN,which has the correlation with the formation and severity of related indexes.Fibrinogen can be used as a laboratory indicator to assist in the diagnosis of irreversible lesionsin the renal pathology of HSPN children.

Objective:To investigate the association of R-loop binding proteins with prognosis and chemotherapy efficacy in lung adenocarcinoma.Methods:The data related to R-loop regulatory genes were obtained from literature of R-loop proteomics and relevant databases.We used 403 cases of lung adenocarcinoma in the Cancer Genome Atlas as training set,and two datasets GSE14814 and GSE31210 in Gene Expression Omnibus as validation sets.The weighted gene co-expression network analysis(WGCNA)was employed to identify R-loop genes with a significant impact on the clinical phenotype of lung adenocarcinoma.Least absolute shrinkage and selection operator(LASSO)regression analysis was utilized to eliminate genes exhibiting multicollinearity.A multivariate Cox regression analysis was employed to scrutinize clinical variables and R-loop characteristic genes that exert independent prognostic effects on patient survival.Subsequently,a risk score model was constructed.The predictive capacity of this model for the prognosis of patients was analyzed and validated.Additionally,the performance of risk model on the anti-tumor drug sensitivity was assessed.The mutations of R-loop genes were analyzed by maftools.The effect of PLEC expression on anti-tumor drug sensitivity was tested on non-small cell lung adenocarcinoma H1299 and A549 cells in vitro.Results:A collection of 1551 R-loop genes were obtained,and 78 genes exhibited significant effects on the clinical phenotype shown on WGCNA.The LASSO regression analysis retained fourteen R-loop genes.A multivariate Cox regression analysis further identified three R-loop genes(HEXIM1,GLI2,PLEC)and a clinical variable(tumor grading)that were associated with patient prognosis.Risk prediction model was established according to the regression coefficients of each parameter.Kaplan-Meier survival analysis showed that the prognosis of high-risk group was significantly worse than that of low-risk group(P<0.01).The time-dependent ROC curve showed that the risk model had good predictive ability in both training and validation sets.Predictive analyses of anti-neoplastic drug sensitivity indicated a diminished responsiveness to both chemotherapy and targeted treatment drugs among high-risk patients.The expression of PLEC was strongly correlated with sensitivity to gefitinib,a classical EGFR inhibitor.Conclusion:R-loop binding proteins have been identified as significant determinants in the prognosis and therapeutic strategies for lung adenocarcinoma,which indicates that therapeutic interventions targeting these specific R-loop binding proteins might contribute to a better survival of the patients.

Objective:To investigate the correlations between the bone mineral densities and biomechanical properties on different layers of the cancellous bone in the proximal tibia.Methods:Quantitative CT was conducted of the 15 specimens of adult male tibia. Based on the artificial destruction levels at the trabecular bone on the tibial plateau, the 15 specimens were randomly divided into 3 groups ( n=5): group A (cancellous bone on the 1.5 cm layer below the articular cartilage), group B (cancellous bone on the 3.0 cm layer under the articular cartilage) and group C (cancellous bone on the 0 to 3 cm range of the subchondral bone). After standing positions were simulated in the 3 sets of specimens, they were connected to a biomechanical testing machine. Twenty-four sites were selected and subjected to a vertical load of 600 N. Strain values and overall displacement values of the specimens were recorded before and after trabecular bone destruction. The correlations were analyzed between bone density and displacement values in groups A and B. The strain values before and after trabecular bone destruction, as well as the overall deformation values of the specimens were compared between the 3 groups. Results:The bone densities of specimens in groups A and B were negatively correlated with the displacement values before and after destruction ( P<0.05). Comparisons of strain values at the 24 sites before and after trabecular bone destruction within 3 groups: There were statistically significant differences in the strain values at 8 sites between before and after trabecular bone destruction in group A ( P<0.05). Of the 8 sites, 6 showed increased strains which were mainly concentrated around the insertion point of the anterior cruciate ligament and the medial tibial plateau. There were statistically significant differences in the strain values between before and after trabecular bone destruction at 3 sites in group B ( P<0.05). The strains at all the 3 sites increased, mainly concentrated behind the surface below the level of destruction. There were statistically significant differences in the strain values at 10 sites in group C between before and after trabecular bone destruction ( P<0.05). Of the 10 sites, 5 showed a decrease in the strain which was concentrated above the destruction plane, and 5 showed an increase in the strain which was concentrated below the destruction plane. The overall deformation values of the specimens in groups A, B, and C were (0.033±0.003) mm, (0.015±0.003) mm, and (0.066±0.007) mm, respectively, showing statistically significant differences between the 3 groups ( P<0.05) as well as between any 2 groups ( P<0.05). Conclusions:Bone mineral density in the cancellous bone of the proximal tibia has some value in assessment of the bone strength. Destruction of the proximal tibial cancellous bone can significantly change the strain distribution on the proximal tibia. The proximal cancellous bone of the tibia plays a key role in stress support and load conduction.

Hyperglycemia is a common complication of critical patients. Currently, clinical assessment of the changes in the blood glucose of critical patients is mainly based on the intermittent monitoring of peripheral blood glucose at a certain time point. This method cannot get the true blood glucose fluctuation, and it is more difficult to find asymptomatic hyperglycemia and hypoglycemia, so the guiding value of blood glucose control is limited. Arterial blood is the most accurate sample of blood glucose monitoring, so it is urgent to ensure the accuracy of arterial blood sample. A continuous arterial blood glucose monitoring equipment was independently developed by general surgical intensive care unit (ICU) of the First Affiliated Hospital of Nanjing Medical University, and National Utility Model Patent of China was obtained. It could greatly improve the efficiency of medical staff, and provide accurate and dynamic statistic data that would be an important basis for doctors' clinical decision-making. The continuous arterial blood glucose monitoring equipment was mainly composed of arterial pressure measuring monitor, program-controlled dynamic blood glucose meter, wire, electric switch, integrated collecting syringe, electric clip, rotary electric bracket, and blood glucose test strips, etc., which could be continuously and dynamically monitor patient blood glucose levels and perform various additional value-added functions such as automatic recording and alarming.

Objective To investigate the effect of diabetes mellitus (DM) on adenosine postcondi-tioning-induced reduction of myocardial ischemia-reperfusion (I∕R) injury in rats. Methods Adult male Sprague-Dawley rats, weighing 230-260 g, were used in the study. Type 2 DM was induced by high-fat diet and intraperitoneal l% streptozocin 35 mg∕kg and confirmed by fasting blood glucose concentration>16. 7 mmol∕L 72 h later. Eighteen rats with type 2 DM were divided into 3 groups (n= 6 each) using a ran-dom number table: sham operation group (DS group), I∕R group (DI∕R group) and adenosine postcondi-tioning group (DAP group). Eighteen healthy nondiabetic rats were selected and randomly divided into 3 groups (n= 6 each): sham operation group (NS group), I∕R group (NI∕R group) and adenosine postcon-ditioning group (NAP group). Myocardial I∕R was induced by 30 min occlusion of the left anterior descend-ing branch of coronary artery followed by 2 h of reperfusion. Venous blood samples were collected from the femoral vein at 2 h of reperfusion for measurement of plasma cardiac troponin I (cTnI) and creatine kinase-MB (CK-MB) concentrations (by enzyme-linked immunosorbent assay). The rats were then sacrificed im-mediately after blood sampling for determination of the myocardial ischemic area and infarct size. Results The plasma cTnI and CK-MB concentrations were significantly increased, and the percentage of myocardial infarct size was increased after myocardial I∕R in nondiabetic and diabetic rats. Adenosine postconditioning significantly decreased plasma cTnI and CK-MB concentrations and percentage of myocardial infarct size in nondiabetic and diabetic rats (P<0. 05). Compared with group NAP, the plasma concentrations of cTnI and CK-MB were significantly increased, and the percentage of myocardial infarct size was increased in group DAP (P<0. 05). Conclusion DM can weaken cardioprotection induced by adenosine postcondition-ing in rats.
