OBJECTIVE: To investigate the potential protective role of Cistanche extracts on 1-methyl-4-phenylpyridinium ion (MPP(+))-induced Parkinson's disease (PD) cellular model, and to find out whether this effect is achieved through the regulation of growth arrest- and DNA damage-induced gene 153 (GADD153). METHODS: MPP(+))-induced cellular injury and the protective effect of Cistanche extracts on the SH-SY5Y cell line viability treated by MPP(+)) were investigated by using methyl thiazolyl tetrazolium (MTT) assay. The mRNA of GADD153 in SH-SY5Y cell line treated by MPP(+)) and Cistanche extracts were evaluated by reverse transcriptase-polymerase chain reaction (RT-PCR). The protein level of GADD153 in SH-SY5Y was assessed by Western blotting. RESULTS: Cistanche extracts (100 mug/ml) increased the cell viability (P<0.01). And the mRNA of GADD153 in the Cistanche extracts pretreatment group was much less than that in the MPP(+)) group (P<0.01). The result of Western blotting showed that GADD153 had a lower level in the Cistanche extracts pretreatment group, compared with MPP(+)) group, especially in the 100 microg/ml group (P<0.01). CONCLUSION: Cistanche extracts pretreatment has a protective effect on the MPP(+))-treated SH-SY5Y cell line, and its down-regulation of GADD153 may contribute to the effect.

Objective To optimize extraction process of flavonoids from Toosendan Fructus.Methods Three parameters that significantly affect the extraction rate of flavonoids, ratio of material to water, extraction time and ethanol concentration, were taken into consideration for extraction ratio of flavonoids from Toosendan Fructus. Based on the results of single-factor experiment, the extraction parameters of flavonoids from Toosendan Fructus were optimized by Box-Behnken of response surface methodology (RSM).Results The optimum extraction conditions were as follow: material to water ratio was 1:35; extraction time should be 3 h; ethanol concentration was 70%. The extraction ratio was up to 0.587 3% in the optimum extraction conditions.Conclusion The actual value is highly matching the theoretically value of RSM model. The results indicated that this method can rationally optimize extraction process of flavonoids from Toosendan Fructus.

Objective To investigate the effect of early rehabilitation on neurological function and cerebral blood flow of patients with acute cerebral infarction.Methods100 cases of acute cerebral infarction were randomly divided into the rehabilitation group(53 cases) and control group(47 cases).Both groups received the routine treatment;besides,patients in the rehabilitation group were treated with early rehabilitation training.The treatment efficacy was assessed by neurological function deficit evaluation,and the cerebral blood flow was measured by transcranial Doppler(TCD) before and 30 days after treatment.ResultsThe scores of neurological function deficit evaluation of all patients in each group decreased after treatment,but the scores of the rehabilitation group were obviously lower than that of the control group(P<0.01);and the results of TCD of the rehabilitation group were also superior to that of the control group(P<0.01).ConclusionEarly rehabilitation training may obviously improve neurological function and cerebral blood flow of patients with acute cerebral infarction.

We predicted the anti-hepatitis B virus (HBV) active components and mechanism of Salvia miltiorrhiza based on network pharmacology. The active components of S. miltiorrhiza were obtained through TCMSP, PubChem database and literature research. The potential targets of the active components and HBV infection were predicted by SwissTargetPrediction and GeneCards databases, respectively. The protein-protein interaction (PPI) network was constructed by String database. Cytoscape software was adopted to construct a visual network of active component-disease target and perform topological analysis. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed using DAVID platform. The molecular docking of key components and core targets was carried out by AutoDock Vina software. We screened out a total of 38 active components and 178 disease-component overlapping targets. Enrichment analyses obtained 405 related GO items and 68 signaling pathways, such as T/B cell receptor signaling pathways, PI3K/AKT signaling pathway, and mTOR signaling pathway. According to the results of molecular docking, most characteristic components of S. miltiorrhiza (miltionone Ⅱ, miltirone, protocatechuic acid, lithospermic acid, protocatechualdehyde) showed good affinity with the key targets (PIK3CA, APP, STAT3,AKT1 and mTOR). Furthermore, the anti-HBV activity of lithospermic acid, the representative active component of S. miltiorrhiza, and its regulation on PI3K/AKT and mTOR signaling pathways were investigated in an HBV replicating mouse model. Animal welfare and experimental procedures follow the regulations of the Animal Ethics and Welfare Committee of Hubei University. The results showed that lithospermic acid significantly inhibited HBV DNA replication, reduced serum HBsAg and HBeAg levels, and decreased the phosphorylation protein expression levels of AKT and mTOR in liver, indicating that lithospermic acid might exert the anti-HBV activity by regulating PI3K/AKT and mTOR signaling pathways.

BackgroundDiabetic retinopathy (DR) is the result of the cytokine network disorders,the imbalance of angiogenic factor and vascular inhibitory factor is the start factor.ObjectiveTo analyze the levels of CXC chemotatic factors of type 2 diabetes mellitus patients,evaluate the clinical application value of them in different clinical types of DR using receiver operating characteristic (ROC)analysis and to approach the new way of individualized treatment.Methods This was a prospective research.The gold standard was ophthalmolscope and fundus fluorescein angiography.The levels of CXC chemotatic factors and multiplicaiton factors were measured in 96 cases with type 2 diabetes mellitus (66 cases with retinopathy and 30 cases without retinopathy as control).The assessment tasks were performed for these index and courses of DR with ROC curve.Results The expression of age,course of disease has significant difference in different courses of DR ( F =8.507,P =0.001 ; F =28.143,P =0.000).Compared with the control group,the expression of growth-related oncogene-α ( GROα ) ( t =- 2.172,P =0.035,AUC =0.625 ),whole blood viscosity 200 ( t =- 3.724,P =0.001,AUC =0.904 ) and neutrophilic leukocyte (t=-2.562,P =0.013,AUC =0.577 ) has significant difference in the group of mild NPDR.Compared with the control group,the expression of interferon-γ-inducible protein 10 ( IP-10 ) ( t =-3.591,P =0.001,AUC =0.592 ),platelet derivation growth factor-BB ( PDGF-BB ) ( t =- 3.233,P =0.003,AUC =0.735 ),vascular endothelial growth factor(VEGF) ( t =- 3.617,P =0.001,AUC =0.776 ),C peptide ( t =- 3.366,P =0.002,AUC =0.962 ),leukocyte ( t=-3.201,P =0.003,AUC =0.852) and neutrophilic leukocyte(t =-4.201,P=0.000,AUC =0.852) has significant difference in the group of moderate and severe NPDR.ConclusionsCXC chemotatic factors may act as reactivator in the pathogenesis of DR,GROα and IP-10 may be useful for clinical monitoring of the severity of DR,and evaluating the imbalance state of chemotatic factors maybe a new approach to clinical monitoring and prognosis of DR.
