Objective To observe the Influence of Daotan decoction on nonalcoholic steatohepatitis (NASH) in Rats, and its relative mechanisms was analyzed. Methods The rat nonalcoholic steatohepatitis model was induced by high fat diet. The rats of therapeutic groups were treated with small, middle and high dose Daotan decoction respectively. Their general condition, liver index, and the fat change and inflammation of liver were observed. The serum ALT、triglyceride(TG), total cholesterol(TCH), low density lipoprotein(HCL-C), high density lipoprotein(LDL-C)were determined respectively. Results The liver index of therapeutic groups were markedly reduced respectively compared with those of model group(P0.05).

To analysis of Dengzhan Xixin injection (DZI) in treatment of cerebral infarction (EBHM) in the real world population characteristics and concomitant medication. By selecting the 20 hospital information system (HIS) used in the database of DZI and primary diagnosis of 2 484 cases of cerebral infarction patients information, use the Apriori algorithm to construct the model, using Clementine 12.0 analysis, cerebral infarction complicating diseases, commonly used drug combination analysis of DZI. The results showed that patients with more males than females (1.63: 1); age > 46 in older persons, treatment 7-14 days accounted for the majority of patients with hypertension, cerebral infarction, diabetes, coronary heart disease and other diseases; common drug combination can be divided into seven categories: medicine of antiplatelet therapy (aspirin, clopidogrel hydrogen), hypolipidemic drugs (atorvastatin, probucol), calcium channel blockers (cinepazide), cerebral protection drugs (laci staw), to improve cerebral circulation drugs (alprostadil), other traditional Chinese medicine injection (Shuxuetong injection, Xueshuantong), treatment with underlying disease: nifedipine, metoprolol, isosorbide dinitrate etc. The clinical cure rate and improvement rate of 97.60%. The next step needs to be combined with clinical practice, carry out analysis of effectiveness and safety of the combination scheme, and provide reference for clinical rational drug use.

BACKGROUND:Topping-off technique can be used for fixation treatment through the combination of fusion and interspinous dynamic device, in order to prevent or slow down the adjacent lumbar segment degeneration.
OBJECTIVE:To obverse the protective effect of Topping-off technique (posterior lumbar interbody fusion
procedure combined with the fixation of dynamic interspinous device Coflex) for the degenerative intervertebral disc. METHODS:A total of 32 patients with degenerative lumbar diseases who had been treated with Topping-off technique were included in this study. The Oswestry disability index, the Japanese Orthopaedic Association scores, range of motion for Coflex implanted segment and during the relative signal intensity of the Coflex implanted segment in MRI image were recorded and calculated preoperatively and the entire fol ow-up period.
RESULTS AND CONCLUSION:Al patients were fol owed-up for 20.6 months averagely. Up to the last fol ow-up, the Oswestry disability index and Japanese Orthopaedic Association scores were significantly improved when compared with those before treatment (P<0.001). There was no significant difference in the range of motion for Coflex implanted segment before and after treatment (P=0.19). The relative signal intensity of the Coflex implanted segment was significantly improved when compared with that before treatment (P<0.01). The clinical application of the Topping-off technique showed a protective effect on the intervertebral disc.

Objective To study the inhibitory effect of panax notoginseng saponins (PNS) on 3-nitrotyrosine (3-NT) formation in brain induced by heme/NO2 -/H2O2 or ONOO - pathways in vitro. Methods According to the two major pathways of 3-NT formation in vivo, the models of protein nitration induced by heme/NaNO2/H2O2 or ONOO-system were established, respectively, in vitro. Bovine serum albumin (BSA)/rat plasma protein or rat brain homogenate protein were utilized as reactive substrates in both systems. Samples were divided into blank-control group, 3-NT group and PNS group (including low-, medium-and high-concentration subgroups). In 3-NT group, samples were exposed to heme/NaNO2/H2O2 or ONOO-system, respectively, at 37℃for 30 min, whereas in PNS group, samples were pre-incubated with PNS (at final concentrations of 50 mg/L, 100 mg/L, and 200 mg/L) at 37℃for 5 min before the nitrating system exposure. The 3-NT level in each group was detected by Western blot assy. Results Compared with the blank-control group, both heme/NaNO2/H2O2 and ONOO-system can induce significant 3-NT generation in BSA/rat plasma protein or rat brain homogenate protein (P<0.05). Compared with model group, PNS pre-treatment markedly inhibited 3-NT expression in BSA/rat plasma protein in a dose-dependent manner (P<0.05), the inhibitory effect of low intervention on the level of 3-NT in rat brain homogenate protein was not significant (P>0.05). Medium- and high-concentrations of PNS pre-treatment markedly inhibited 3-NT accumulation, with maximum effect at the concentration of 200 mg/L (P<0.05). Conclusion Medium- and high-concentrations of PNS can inhibit 3-NT formation in brain tissue mediated by either heme/NO2-/H2O2 or ONOO-pathways, implying that potential neuroprotective action against 3-NT involves pathological conditions, like trauma, stroke, and neurodegenerative diseases.

This article was aimed to study the effect ofXiao-Qing-LongDecoction (XQLD) on plasma AngⅡ, ALD, Na+-k+-ATPase content, and plasma AT1 and AT2 mRNA expressions in Cor pulmonale rats, in order to further explore the mechanism of ventilating lung qi for diuresis. A total of 60 Wistar rats were randomly divided into the normal group, model group and XQLD, with 20 rats in each group. The enzyme-linked immunosorbent assay (ELISA) method was used to determine the AngⅡ, ALD and Na+-k+-ATPase content. The fluorescence quantitative PCR was used to detect the AT1 and AT2 mRNA expression. The results showed that compared with the normal group, the AngⅡ, ALD and Na+-k+-ATPase contents in the model group were significantly increased (P< 0.05, orP< 0.01). Compared with the model group, the AngⅡ, ALD and Na+-k+-ATPase contents in the XQLD group were obviously decreased (P< 0.05). Compared with the normal group, AT1 mRNA expression was increased; and AT2 mRNA expression was decreased in the model group (P<0.05, orP< 0.01). Compared with the model group, AT1 mRNA expression was decreased; and AT2 mRNA expression was increased in the XQLD group (P < 0.01). It was concluded that XQLD can effectively regulate the AT1 and AT2 mRNA expressions, influence ALD content to ventilate lungqi for dieresis.

Objective To study the effect of Shuanghuanglian injection on CRP, PCT and IL-6 in pneumonia children.Methods 68 cases of pneumonia children were selected and divided into the control group and the experiment group.33 case in the control group and 35 cases in the experiment group.The two groups were treated with conventional symptomatic treatment and anti infection treatment for the two groups were implemented routine symptomatic treatment and anti infection treatment.The control group were treated with cefotaxime sodium injection, the experiment group were treated on the base with Shuanghuanglian injection.CRP, PCT and IL-6 in serum were compared before and after the treatment.Results Compared with the control group, the level of CRP in serum was lower(P<0.05), the level of PCT in serum was lower(P<0.05), the level of IL-6 in serum was lower(P<0.05).Conclusion Shuanghuanglian injection has a good clinical effect on children’s pneumonia.It is speculated that the mechanism is related to the decrease of serum CRP and IL-6 level.
