Ginsenoside Rg1 ( Rg1 ) is a monomer isolated from ginseng, which has a variety of pharmacological activities. Rg1 can obviously regulate hematopoietic stem cells, mesenchymal stem cells, neural stem cells and endothelial progenitor cells proliferation, differentiation, aging, secretion and so on by mul-tiple mechanisms. Rg1 has important therapeutic effects on the reparation of tissues, organs damage and aging. This review de-scribes the current knowledge on the effects of Rg1 on the char-acteristics and functions of adult stem cells.

thoracic. No immunoreactive product was seen in the ventral horn. The possible functions of CGRP in substantia gelatinosa of the spinal dorsal horn were discussed.

Objective To investigate the effect of lipid soluble fraction in the radix of Salvia miltiorrhiza (FSM) on conditioned place preference (CPP) in mice induced by morphine and preliminarily identify the fraction in the radix of S. miltiorrhiza. MethodsMorphine or NS was sc injected every other day to induce the obvious CPP in mice for 6 d. Before 30 min of sc injecting morphine, mice were ip administered different doses of lipid soluble fraction in the radix of S. miltiorrhiza. RP-HPLC method was used to identify the major component in the lipid soluble fraction in the radix of S. miltiorrhiza. ResultsThe staying time in morphine-paired white compartment was significantly prolonged. After treatment with lipid soluble fraction in the radix of S. miltiorrhiza (40 mg/kg, ip), the staying time in morphine-paired white compartment was significantly shortened (P

Objective To determine an early and noninvasive predictor of chronic kidney diseaase(CKD),by detecting the correlation between the urinary Col-Ⅳ concentration,the renal tissue and renal lesions in patients with CKD Col-Ⅳ expression.Methods 98 CKD patients proved by renal biopsy were selected and 76 healthy people were enrolled as control.Urinary and serum Col-Ⅳ concentration were examined by enzyme-linked immunosorbent assay(ELISA).Renal Col-Ⅳ expression was detected by immunohistochemistry.Renal injury grade was semiquantitative by CMIAS image analysis system.The association between urinary Col-Ⅳ level and renal Col-Ⅳexpression,as well as renal lesion was analyzed,meanwhile the proteinuria and glomerular filtration rate(GFR)were analysed simultaneously.Results Urinary Col-Ⅳ level in patients with CKD was significantly higher than that in control,however,there was no difference in blood Col-Ⅳ level.Expression of Col-Ⅳ could be found in the sclerosing glomeruli and tubulointerstitial tissue,and Col-Ⅳ expression degree was consistent with lesion degree.Urinary Col-Ⅳ level was correlated positively with renal Col-Ⅳ expression,as well as with density of glomerular basement membrane and interstitial damage.Elevated urinary Col-Ⅳ concentration was observed in patients with mild renal sclerosis prior to the change of GFR.No correlation between urinary Col-Ⅳ concentration and proteinuria was observed.Conclusions These results suggested urinary Col-Ⅳ concentration reflected renal Col-Ⅳ expression and renal sclerosis,and could predict the progression of CKD.

Objective To analyze characteristics of severe liver trauma and efficacy of different surgical procedures. Methods Clinical data of 109 patients with severe liver trauma treated in the recent 10 years were retrospectively analyzed. Debriding suture was performed in 32 patients, gauze tamponade in 5, debridement hepatectomy in 59 and anatomical hepatectomy in 13 patients. Results In all the 109 patients, 92 were cured and 17 died. The dead patients included 3 with grade Ⅲ trauma,9 with grade Ⅳ trauma, and 5 with grade V trauma. Among the dead patients, there were 3 patients with simple liver injury (17.6%) and 14 with associated injury (82.4%). Conclusion Right hepatic serious damage is the main type of severe liver trauma and is always complicated with associated injury and needs emergency treatment. Application of the most appropriate surgical approach according to the traumatic condition is important to promote the successful rate of treatment.

Objective To comfirm the anti-fibrotic effect of spironolactone and investigate the influence of spironolactone on concentration of angiotensinⅡ(AngⅡ) in rat hepatic fibrosis. Methods Ninety male Sprague-Dawly rats were randomly divided into three groups: control group (8 rats, subcutaneous injection of pure peanut oil, normal diet), model group (42 rats, subcutaneous injection of 40% CCl 4, 0.3 mL/100 g, twice a week, high cholesterol and low protein diet, 5% alcohol as the drink), and spironolactone group (40 rats, same dosage of CCl 4, high cholesterol and low protein diet, gastropufusion of spironolactone at the dose of 100 mg?kg -1?d -1). The animals were sacrificed at 2, 4, 6 and 8 weeks of administration. AngⅡ was assayed by radioimmunoassay. The liver tissues were stained, coded and examined. Results ① The general conditions of the rats of spironolactone group were better than those of the model group. The degree of fibrosis and the area of collagen in the liver of spironolactone group were less than those of the model group after the 4th week (P

Promotion of outstanding people to head nurses is key to hospital nursing management.In view of the current shortcomings in the analysis of appraisal data and the interpretation of appraisal results,the analysis of means(ANOM)method is introduced to the process of hospital human resource management.The proposed method aims to solve the problem when the score differences between interviewers are great and the score differences between candidates are small.An example for head nurses' promotion appraisal in a hospital is offered to demonstrate that statistical tools can provide the decision support for hospital personnel selection.Finally,the application differences between ANOM and analysis of variance(ANOVA) in human resources appraisal are compared.

Objective To assess the value of SYNTAX score to predict major adverse cardiac and cerebrovascular events (MACCE) among patients with three-vessel or left-main coronary artery disease undergoing percutaneous coronary intervention.Methods 190 patients with three-vessel or left-main coronary artery disease undergoing percutaneous coronary intervention (PCI) with Cypher select drug-eluting stent were enrolled.SYNTAX score and clinical SYNTAX score were retrospectively calculated.Our clinical Endpoint focused on MACCE,a composite of death,nonfatal myocardial infarction (MI),stroke and repeat revascularization.The value of SYNTAX score and clinical SYNTAX score to predict MACCE were studied respectively.Results 29 patients were observed to suffer from MACCE,accouting 18.5％ of the overall 190 patients.MACCE rates of low ( ≤ 20.5 ),intermediate ( 21.0-31.0 ),and high ( ≥ 31.5 ) tertiles according to SYNTAX score were 9.1％,16.2％ and 30.9％ respectively.Both univariate and multivariate analysis showed that SYNTAX score was the independent predictor of MACCE.MACCE rates of low ( ≤ 19.5 ),intermediate( 19.6-29.1 ),and high( ≥29.2) tertiles according to clinical SYNTAX score were 14.9％,9.8％ and 30.6％ respectively.Both univariate and multivariate analysis showed that clinical SYNTAX score was the independent predictor of MACCE.ROC analysis showed both SYNTAX score ( AUC =0.667,P =0.004) and clinical SYNTAX score ( AUC =0.636,P =0.020) had predictive value of MACCE.Clinical SYNTAX score failed to show better predictive ability than the SYNTAX score.Conclusions Both SYNTAX score and clinical SYNTAX score could be independent risk predictors for MACCE among patients with three-vessel or left-main coronary artery disease undergoing percutaneous coronary intervention.Clinical SYNTAX score failed to show better predictive ability than the SYNTAX score in this group of patients.

Objective To compare the application of Goldman , CARPREG and ZAHARA in predicting cardiac outcomes in pregnant women with congenital heart disease. Methods A retrospective analysis of 144 pregnant women with CHD , enrolled in The Third Affiliated Hospital of Guangzhou Medical University between Jan 1992 and June 2015 was conducted. The mortality and the incidence of cardiac events were counted by three risk estimation methods. The sensitivity and calibration of three systems were compared by using Hosmer-Lemeshow goodness of-fit analysis and Aera Under Curve (AUC). Results In terms of mortality rates, the sensitivity of CARPREG was higher than that of Goldman (AUC:0.874 and 0.889 respectively;P = 0.568 >0.05);. In terms of the incidence of cardiac events, the sensitivity of ZAHARA was higher than that of Goldman (AUC:0.912 and 0.773 respectively;P = 0.063 > 0.05); Conclusions All 3 risk estimation methods have good performance in sensitivity of predicting the incidence of cardiac events and mortality in pregnant women with CHD. The ZAHARA has a better calibration in predicting the incidence of cardiac events , and we recommend ZAHARA as the first choice of evaluation system for this kind of patients.
