Ginseng and its effective components are famous for their influence to enhance human immunity, regulate endocrine and antioxidant action. However, the different effects of different components are not clear. In this study, Wistar rats were used to study the effects of main components of ginseng, including total ginsenoside, panaxadiol saponins, panaxtrol saponin and ginseng polysaccharide. The results showed that the effects of panaxadiol saponins and ginseng polysaccharide on improving animal immune organ weight, plasma interleukin 2 (IL-2), interleukin 6 (IL-6), plasma gamma-interferon (IFN-γ), tumor necrosis factor alpha (TNF-α) were better than that of the other groups. Total ginsenoside and panaxtrol saponin can effectively increase the concentration of spleen NK cells (NKC) while panaxadiol saponins and ginseng polysaccharide can significantly increase the concentrations of rat plasma adrenocorticotrophic hormone (ACTH), corticosterone (CORT) and thyroid stimulating hormone (TSH). As for the effect of increasing organization nitric oxide (NO) and superoxide dismutase (SOD), glutathione (GSH) and malondialdehyde (MDA), total ginsenoside is better than that of other groups. In brief, different components in ginseng possess different effects on enhancing immunity, regulating endocrine and resisting oxidation. Panaxadiol saponins and ginseng polysaccharide are better in enhancing immune, and total ginsenoside shows advantages in resisting oxidation and stress.

Objective:To systematically evaluate the predictive value of neutrophil-lymphocyte ratio (NLR) in acute kidney injury (AKI).Methods:All studies about the predictive effect of NLR on AKI were searched in the National Medical Library of the United States PubMed Database, the Embase database in the Netherlands, the Chinese Biology Medicine disc (CBMdisc) and the Chinese Evidence Based Medicine Cochrane Centre Database (CEBM/CCD). The data updated by October 2020, and regardless of language, region or whether blind method was used. Two authors independently extracted data and evaluated the quality of the studies. Data extracted from the studies were analyzed with RevMan 5.3 to assess the predictive value of NLR on AKI. A subgroup Meta-analysis was conducted to assess the predictive value of NLR on AKI according to different countries, different disease types (cardiovascular surgery, infectious diseases, other diseases including burns, cirrhosis, and emergency), and different sample sizes (≤ 300 cases and > 300 cases). The publication bias of included studies about the predictive effect of NLR on AKI were assessed by funnel plots.Results:A total of 11 studies were included in this Meta-analysis, including 4 997 patients, 1 308 patients in AKI group, and 3 689 patients in non-AKI group. The Meta-analysis results showed that: increased NLR had predictive value for the occurrence of AKI [mean difference ( MD) = 2.73, 95% confidence interval (95% CI) was 1.78-3.68, P < 0.000 01]. Subgroup analysis showed that increased NLR had predictive value for the occurrence of AKI in patients from Southeast Asia ( MD = 4.04, 95% CI was 1.09-6.99, P = 0.007) and Eurasia ( MD = 2.51, 95% CI was 1.12-3.90, P = 0.000 4). Increased NLR had predictive value for the occurrence of AKI in patients undergoing cardiovascular surgery ( MD = 0.77, 95% CI was 0.34-1.20, P = 0.000 4), infectious diseases ( MD = 4.74, 95% CI was 1.51-7.96, P = 0.004) and other diseases ( MD = 8.53, 95% CI was 6.26-10.80, P<0.000 01). Increased NLR had predictive value for the occurrence of AKI in studies with a sample size of ≤ 300 cases ( MD = 6.02, 95% CI was 4.90-7.14, P <0.000 01) and > 300 cases ( MD = 1.32, 95% CI was 0.61-2.03, P = 0.000 3). There was no significant publication bias in the included studies assessed by funnel plots. Conclusion:NLR is an important predictive tool for AKI.

AIM:To optimize formulation of Xiao'er Magan Orally Disintegrating Tablet by central composite design-response surface methodology. METHODS:By two factors and five levels central composite design,independent variables were the proportion of optimized microcrystalline cellulose 50 and mannitol and the pressure,while disintegrating time and tensile strength were dependent variables. Binary linear and quadratic models were used to estimate the relationship between the dependent and the indepedent variables,and to delineate response surface method and overlay contour plots in order to select the optimal formulations. RESULTS:The binomial regression equation were TS =0. 096 88X1 + 0. 027 6X1X2(r = 0. 759),DT = 9. 845 4X1 -63. 196X2 + 40. 092 9X22 (r = 0. 838) which indicated the quantitative relationship between the factors and the evaluation indexes was characterized. The optimal formulation were the ratio of microcrystalline cellulose 50 and mannitol in the range of 0. 35 and 0. 6,and the pressure was in the range of 6 and 8 KN. CONCLUSION:The optimized formulation validation is close to the estimated value,indicating that the method has a good predictability and reliability.

Objective To investigate the clinical effect of preoperative nutritional treatment and perioperative nutrition support for the patients with esophageal cancer.Methods According to the digital table,90 patients with esophageal cancer were divided into the control group(15 cases),preoperative nutrition group(25 cases),postoperation nutrition group(25 cases)and preoperative nutrition + postoperation nutrition group(25 cases).The postoperative quality of life and the complications were compared.Results Postoperative quality of life in the preoperative nutrition group,postoperation nutrition group and preoperative nutrition + postoperation nutrition group were all better than that in the control group(t =14.76,15.13,17.87,all P ＜ 0.05).The incidence rate of postoperative complications in patients received nutritional intervention significantly decreased than in the control group(x2 =9.17,12.13,19.18,all P ＜ 0.05).Conclusion The preoperative nutrition and postoperation nutrition can improve the postoperative quality of life and reduce the incidence rate of the complications.

AIM:To investigate the myocardial protective effect of endometrial stem cell ( EnSC)-derived cyto-kine cocktail ( EdCC) on myocardial ischemic reperfusion injury and the MEK-ERK signaling pathway.METHODS: A mouse model of myocardial ischemic reperfusion injury was established.Infarct area, cell apoptosis, and expression of cleaved caspase-3 and phosphorylatied ERK1/2 were determined by TTC/Evans blue staining, TUNEL assay and Western blot, respectively.RESULTS:The mesenchymal characteristics were observed in the EnSCs with expressing CD90 and in absence of CD34 and CD45.EdCC contained (6 811 ±312) ng/g epidermal growth factor (EGF) protein.The phospho-rylation of ERK1/2 markedly increased after injection of EdCC, but was abolished by MEK1 inhibitor PD98059 ( 5 mg/kg) .EdCC decreased the infarct area and apoptotic cell number in the border zone and inhibited caspase-3 activation. However, the effects were abolished by MEK1 specific inhibitor PD98059.EGF did not decrease the infarct area, but the EGF receptor antagonist AG-1487 (6 mg/kg) partly abolished the myocardial protective effect of EdCC.CONCLUSION:EdCC protects the myocardium from ischemic reperfusion injury via activating MEK1-ERK signaling pathway, indicating an essential role in the transmission of stem cell therapy from the cell transplantation to cytokine based strategy.

This study is to investigate the protective effect of mangiferin on NF-kappaB (P65) and IkappaBalpha expression in peripheral blood mononuclear cell (PBMC) in rats with cigarette smoke induced chronic bronchitis. The rat model with chronic bronchitis was established by cigarette smoke. Real-time fluorescence RT-PCR was executed for evaluating the NF-kappaB (P65) and IKkappaBalpha gene expression in mononuclear cell, and flow cytometry for their protein expression. The serum hs-CRP (high-sensitivity C-reactive proteins) and TNF-alpha (tumor necrosis factor-alpha) were detected by enzyme-linked immunosorbent assay. The histopathological score was obtained from lung tissue HE staining slides of lung tissue. The results showed that mangiferin could markedly suppress the NF-kappaB (P65) mRNA and protein expression in mononuclear cell, while promote the IkappaBalpha mRNA and protein expression. Furthermore, mangiferin could lower serum hs-CRP and TNF-alpha level, and reduce the chronic inflammatory damage of bronchiole. These results suggested that mangiferin could notably ameliorate chronic bronchiole inflammation induced by cigarette smoke, and this protective effect might be linked to the regulation of NF-kappaB (P65) and IkappaBalpha expression in mononuclear cell.
