    Weiqing ZHANG;Jinhuan ZHANG;Zhulin WU;Lisheng PENG;

    [Objectives] To make a systematic evaluation of the clinical efficacy and safety of Shenqi Fuzheng Injection in the treatment of colorectal cancer. [Methods] Databases,such as China National Knowledge Infrastructure( CNKI),Wanfang,China biomedical literature service system( CBM),CQVIP,Medline,and Cochrane,were searched for the time before April 2017. The randomized controlled trial( RCT) that met the inclusion criteria was screened. Then,quality evaluation was made based on the modified Jadad scale. Data were extracted and meta-analysis was made with the aid of Review Manager 5. 3. [Results] Finally,21 papers met the inclusion criteria,including 2 high quality papers. The average Jadad score was 2. 5 points,1 589 patients were included. Meta-analysis results showed that the intervention of the experimental group could improve the quality of life[OR = 3. 32,95% CI( 2. 33,4. 74),P < 0. 000 01]; improve the short-term efficacy[OR =1. 68,95% CI( 1. 26,2. 24),P =0. 000 4]; reduce the incidence of adverse chemotherapy reactions such as reducing the gastrointestinal reactions[OR = 0. 33,95% CI( 0. 25,0. 43),P < 0. 000 01],reducing myelosuppressive reactions[OR = 0. 33,95% CI( 0. 24,0. 46),P < 0. 000 01]; improve the immune functions,such as increasing CD4/CD8 cell ratio[WMD = 1. 19,95% CI( 0. 24,0. 41),( P <0. 000 01) ],and increasing the number of NK cells[WMD =1. 72,95% CI( 5. 62,14. 30),( P <0. 000 01) ]. [Conclusions]The clinical effect of Shenqi Fuzheng Injection in the treatment of colorectal cancer is better than that of chemotherapy alone,but it needs more highquality RCTs to improve the level of research.

    [Objectives] To evaluate the effects of Huanglian Jiedu Decoration( HLJD) on the treatment of rat gingivitis with excess internal heat through injecting lipopolysaccharide( LPS) in tooth-supporting tissues. [Methods]Gingival inflammation was established by LPS injection. Male SD rats were randomly divided into 7 groups: normal control group( no treatment group),solvent control group,model group( LPS injection),HLJD low dose group( 0. 25 g/kg),HLJD medium dose group( 0. 50 g/kg),HLJD high dose group( 1. 00 g/kg),and metronidazole and fenbufen capsule( MFC) group. Water intake and urine volume were observed through metabolic cage feeding; gingival tissue protein expressions were detected by LC-ESI-MS/MS method; oxidative stress-related molecules such as total superoxide dismutase( T-SOD) and hydrogen peroxidase catalase( CAT) were detected by the biochemical kit combined with a microplate reader; expressions of TSC related with energy metabolism-related signaling pathway were detected by western blotting. [Results]When rat gingivitis was injected by LPS,both water intake and urine volume were decreased,the levels of T-SOD and CAT were decreased,and the expressions of fructose-bisphosphate aldolase C,triosephosphate isomerase 1 and TSC2 were increased. Huanglian Jiedu Decoration can increase water intake and urine volume,increase the levels of T-SOD and CAT,reduce the expressions of fructose-bisphosphate aldolase C and triosephosphate isomerase 1,and inhibit the expression of energy metabolism-related pathway molecule TSC2. [Conclusions] Huanglian Jiedu Decoration can treat rat gingivitis through inhibiting energy metabolism and oxidative stress such as TSC signal pathway and glycolysis related molecules.

  • Effects of Yupingfeng Polysaccharides on the Spleen Tissue Structure of Acute and Chronic Immunocompromised Mice

    Hua DENG;Hong YANG;

    [Objectives] To study the protective and recovery effects of Yupingfeng polysaccharides( YPF-P) on spleen tissue structure of acute and chronic immunocompromised mice. [Methods]First,90 mice in the protective group were injected with cyclophosphamide to replicate the chronic immunosuppressive model,and observe the protective effects of different doses of YPF-P on the spleen; 120 mice in the recovery group were injected with cyclophosphamide continuously to replicate the acute immune injury model,to observe the effects of YPF-P on spleen recovery. Besides,YPF-P positive control group was established to observe its effects on the spleen structure and function of normal mice. Testing indicators include spleen morphology and tissue structure,body mass,and spleen index. [Results]In the protective group and the recovery group,the spleen volume of the mice with different YPF-P doses increased significantly,and lymphocytes proliferated,showing obvious structural compensation and repair,and showing a dose-effect relationship. In the positive control group,the spleen function of the normal mice was significantly enhanced,and the spleen lymphoid tissue showed significant orderly proliferation. [Conclusions]Yupingfeng polysaccharides can effectively protect the function and structure of spleen,improve acute and chronic immune damage induced by cyclophosphamide,greatly promote the recovery of spleen structure and function after immune injury,and also can significant enhance the spleen structure and function of normal mice.

    [Objectives] The aim was to investigate the intervening effect of sodium aescinate on pulmonary fibrosis in rats with acute lung injury( ALI). [Methods] The rats were randomly divided into normal group,model group and sodium aescinate group. The rat model of ALI was induced by administration of oleic acid. The rats in the sodium aescinate group were intravenously injected with sodium aescinate according to the amount of 4 mg/kg for 14 consecutive d. Then,11 rats were selected randomly from each group and slaughtered on Day 1 and Day 14,respectively after last administration. The body mass index,arterial partial pressure of oxygen( PaO_2),oxygenation index( PaO_2/FiO_2),lung index,wet/dry mass ratio of lung,serum IL-1β,TNF-α,PC Ⅲ and TGF-β1 levels of the rats were analyzed. [Results]No significant differences were found in body mass index,lung index or lung wet/dry mass ratio among different groups. Compared with the model group,the PaO_2 and PaO_2/FiO_2 ratio increased significantly( P < 0. 05),the serum IL-1β,TNF-α,PC Ⅲ and TGF-β1 levels declined significantly( P <0. 05),the lung histopathological damage was reduced,and the semi-quantitative histological score( IQA) of damaged lung tissue decreased significantly( P < 0. 01). [Conclusions]Sodium aescinate can reduce the levels of inflammatory factors in rats with ALI,with certain intervening on pulmonary effect.

    Yunfeng XIAO;Yuanyan ZHANG;Wenyan LI;Yuhua WANG;

    [Objectives] To study the effects of Roudoukou-8 San extract on hydrogen peroxide( H_2O_2) induced cardiomyocyte injury of rats and explore its action mechanism. [Methods] The cardiomyocytes of neonatal rats were isolated and cultured,and the H_2O_2 induced cardiomyocyte injury model was established. Methyl thiazolyl tetrazolium( MTT) assay was used to detect the protective effects of Roudoukou-8 San extract on H_2O_2 induced cardiomyocyte. The effects of Roudoukou-8 San on cardiomyocyte morphology were observed under inverted microscope. The contents of lactate dehydrogenase( LDH),creatine kinase( CK) and aspartate aminotransferase( AST) in cell culture medium were determined by automatic biochemical instrument; the levels of malondialdehyde( MDA),superoxide dismutase( SOD) and nitric oxide( NO) in the cells were detected by kit method. The apoptotic morphology of cardiomyocytes was observed by Hoechst fluorescence staining.Cell apoptosis were measured by Annexin V and PI double staining and flow cytometer. [Results]100 μmol/L of H_2O_2 acting 2 h could cause about 50% of cardiomyocyte injury. H_2O_2 model group showed increased cell gap,decreased cell count,cell cytoplasmic vacuoles and other obvious damages. Compared with H_2O_2 model group,in Roudoukou-8 San extract dose groups,cardiomyocyte morphology showed different degrees of improvement,Roudoukou-8 San extract can significantly reduce the content of LDH,CK and AST in H_2O_2 injured myocardial cell culture solution,significantly reduce content of MDA and NO in H_2O_2 injured myocardial cells,increase the SOD activity,and significantly inhibit the apoptosis of H_2O_2 injured myocardial cells. [Conclusions]Through improving the cell survival status,increasing the cell viability,reducing oxidative stress injury,inhibiting inflammatory responses,and inhibiting apoptosis,Roudoukou-8 San extract can improve the state of H_2O_2 induced cardiomyocyte injury,so as to protect H_2O_2 injured myocardial cells.
