Objectives:To compare the effect of glial cell line-derived neurotrophic factor(GDNF) and methylprednisolone(MP) on intracellular free calcium(［Ca2+］i) and capacity of containing water(CCW) after spinal cord injury(SCI).　Methods:Forty-two SD rats were divided into four groups： control, GDNF,MP and GDNF+MP.GDNF and MP were supplied through subarachnoid cavity, tail vein and both of the above after T12 segments spinal cord injury by modified Allen crush method. Animals were executed and specimens were collected at 24 h, 72 h and 168 h after SCI.［Ca2+］i and CCW were measured using Fura-2 method.　Results:Both ［Ca2+］i and CCW of injured spinal cord in GDNF,MP, and GDNF+MP groups were lower than that of the control group at 24 h and 72 h after SCI(P<0.01).Levels of ［Ca2+］i and CCW in GDNF group was much higher than that of MP and MP+GDNF groups(P<0.01),but there was no difference between MP group and MP+GDNF group(P>0.05) 24 hours after SCI. Seventy-two hours after SCI,［Ca2+］i in GDNF group was higher than that in MP group, MP group was higher than MP+GDNF group(P<0.05).CCW of GDNF group exceeded that of MP and MP+GDNF group(P<0.01).［Ca2+］i in GDNF group was higher than that in MP group, and MP group was higher than MP+GDNF group(P<0.01) 7 days postoperatively, but for CCW, there were no differences among GDNF,MP and MP+GDNF groups(P>0.05).　Conclusions: Both GDNF,MP and GDNF + MP groups might reduce ［Ca2+］i and CCW of injured spinal cord. The curative effect of MP for SCI preponderate over that of GDNF, the effect of MP could be enhanced by adding GDNF.

This article was aimed to study the distribution and effects of apolipoprotein E (ApoE) gene polymorphism of different constitutional types among coronary heart disease (CHD) patients with blood stasis syndrome on vascular endothelial cell (VEC) function. The whole gene sequencing method was used to identify genotypes of ApoE gene among 556 CHD patients with blood stasis syndrome, in order to analyze the relationship between polymorphism of ApoE gene and the level of VEC function. The results showed that the frequency of E3/3 genotype of each physical group was significantly lower than that of the healthy group; and the frequency of E3/4 genotype was significantly higher than that of the healthy group. In addition, the frequency of E3/3 genotype in qi deficiency constitution group was higher than that of blood stasis constitution group and yang deficiency constitution group; but the frequency of E3/4 genotype in blood stasis constitution group and yang deficiency constitution group was higher than that of the qi deficiency constitution group. The levels of ET and ET/NO in each of genotype groups of blood stasis constitution, yang deficiency constitution, qi deficiency constitution of CHD patients with blood stasis syndrome were higher than that of the healthy group (P < 0.05). In the genotype group of blood stasis constitution of CHD patients with blood stasis syndrome, the frequency of E3/4+E4/4 genotype ET was higher than that of other genotypes (P < 0.01). The levels of ET, NO, ET/NO in genotype groups of yang deficiency constitution and qi deficiency constitution of CHD patients with blood stasis syndrome were not significantly different. It was concluded that ApoE genotype E3/4, E3/3 may be the susceptible genotypes of blood stasis syndrome in CHD. There is a certain difference among different constitutional types. CHD with blood stasis syndrome patients, who are the constitution of blood stasis, carrying the ApoE gene polymorphism of E4 allele may have the function of increasing the ET level.

Objective To study the distribution of body constitutions of CHD patients with blood stasis syndrome;To explore the relationship between different body constitutions and their blood lipid levels.Methods WANG’s Constitutional Classification was used to diagnose body constitutions of 600 CHD patients with blood stasis syndrome, and analyze the relationship between the different body constitutions and triglyceride (TG) level, low density cholesterol (LDL-C) level, high density cholesterol (HDL-C) level.Results The four most common body constitutions of CHD patients with blood stasis syndrome in Taiyuan area were the constitutions of blood stasis, yang deficiency, qi deficiency and yin deficiency. The TG levels of the four body constitutions were higher than those of healthy people (P<0.01), but there was no obvious difference among TG levels of different body constitutions. The LDL-C level of the patients with the body constitution of blood stasis was higher than that of patients with other body constitutions and healthy people (P<0.01). Compared with healthy people, there was no obvious difference among HDL-C levels of different body constitutions (P>0.05).Conclusion There is a certain difference among the blood lipid levels in different body constitutions of CHD patients with blood stasis syndrome, and the patients of blood stasis syndrome with high LDL-C level are more dangerous than patients with other body costitutions.

Anelectrochemicallyreducedgrapheneoxide/goldnanoparticle-chitosan(ERGO/AuNP-CS) composite film modified glassy carbon electrode ( GCE) was constructed by directly electrochemical reduction of GO, and then assembly of AuNP-CS polycation on the surface. The surface morphologies of different modified electrodes including bare GCE, GCE/GO, GCE/ERGO and GCE/ERGO/AuNP-CS were characterized by scanning electron microscopy ( SEM ) . The differential pulse voltammetric behaviors of the electrodes were investigated, and the results indicated that the composite of ERGO/AuNP-CS exhibited excellent electrocatalytic oxidation activity to uric acid ( UA) molecule. In 0. 10 mol/L of phosphate buffer solution (pH=6. 5) with a scanning rate of 100 mV/s, the proposed composite film modified electrode showed a linear electrochemical response to UA in the range of 0 . 05-110 μmol/L with a detection limit of 12. 4 nmol/L ( S/N = 3 ). The electrode displayed good selectivity, reproducibility and stability in the determination of UA in human serum and urine samples with a recovery of 93 . 8%-104 . 1%. The detection results were agreed with those of conventional spectrophotometry and uricase Kit methods.

To study the effect of pulchinenoside (PULC) on the Frizzled (FZD) expression of adjuvant arthritis ( AA) rats. AA rats were prepared through the toe injection with complete Freund's adjuvant to culture fibroblast-like synoviocytes (FLS). The effect of the oral administration with PULC on the FZD8 expression was detected by the real time qPCR. The effect of FZD8 knockout on the expressions of IL-1, IL-6, IL-8 were detected by MTT and ELISA. The role of miR-375 in the abnomal expression of FZD8 was detected by the real time qPCR. The results showed signfiicant decrease in the FZD8 expression among AA rats, FLS proliferation ater FZD8 knockout and IL-1, IL-6, IL-8 expressions and notable increase in miR-375 expression after the oral administration with PULC. The up-regulated miR-375 expression can inhibit the FZD8 expression. PULC may inhibit the FZD8 expression by up-regulating the miR-375 expression.

The role of pulchinenoside (PULC) in the regulation of MeCP2 expression was investigated in RA model rats. Adjuvant arthritis rats were used as RA model rats, and fibroblast-like synoviocytes (FLS) from the RA model rats were cultured. The effect of 100 mg x kg(-1) PULC gavage treatment on the MeCP2 expression and the effect of MeCP2 siRNA on the expression of SFRP2 and β-catenin were detected by real time qPCR and Western blotting. The role of PULC in the FLS proliferation was detected by MTT. The results showed that the MeCP2 expression was down-regulated, the SFRP2 expression was up-regulated and the FLS proliferation was inhibited in FLS after therapy. MeCP2 siRNA significantly inhibited the MeCP2 expression, up-regulated the SFRP2 expression and inhibited the β-catenin expression in FLS from RA model rats. PULC may increase the SFRP2 expression, inhibit the Wnt signaling and inhibit the FLS proliferation in FLS from the RA model rats by inhibiting the MeCP2 expression.

The study investigated the effects of heat shock protein 70 (HSP70) antisense oligonucleotide (ASODN) on the proliferation and apoptosis of a human hepatocellular carcinoma cell line (SMMC-7721 cells) in vitro. HSP70 oligonucleotide was transfected into SMMC-7721 cells by the mediation of Sofast transfection reagent. Inhibition rate of SMMC-7721 cells was determined by using MTT method. Apoptosis rate and cell cycle distribution were measured by flow cytometry. Immunocytochemistry staining was used to observe the expression of HSP70, Bcl-2 and Bax. The results showed that HSP70 ASODN at various concentrations could significantly inhibit the growth of SMMC-7721 cells, and the inhibition effect peaked 48 h after transfection with 400-nmol/L HSP70 ASODN. Cytometric analysis showed the apoptotic rate was increased in a dose- and time-dependent manner in the HSP70 ASODN-treated cells. The percentage of cells in the G(2)/M and S phases was significantly decreased and that in the G(0)/G(1) phase increased as the HSP70 ASODN concentration was elevated and the exposure time prolonged. Immunocytochemistry showed that treatment of SMMC-7721 cells with HSP70 ASODN resulted in decreased expressions of HSP70 and Bcl-2 proteins, and an increased expression of Bax protein. It was concluded that the HSP70 ASODN can inhibit the growth of the SMMC-7721 cells and increase cell apoptosis by down-regulating the expression of HSP70. HSP70 ASODN holds promise for the treatment of hepatocellular carcinoma.
