ObjectiveTo observe the effect of Xiaoyao powder combined with prozac and psychological therapy on post-stroke depression (PSD).Methods85 PSD patients were randomly divided into the treatment group (n=43) and control group (n=42). All patients were treated with routine therapy, including prozac and psychological therapy. Patients in the treatment group were also given Xiaoyao powder. Scores of Hamilton Depression Scale (HAMD), modified Barthel index (MBI) and Scandinavian Stroke Scale (SSS) of all patients were evaluated before and after therapy.ResultsAfter treatment, the effective rate and MBI scores were significantly higher and scores of HAMD and SSS were significantly lower for patients of the treatment group compared with those of the control group (P<0.01).ConclusionXiaoyao powder combined with prozac and psychological therapy can improve depression and neural function of PSD patients significantly.

OBJECTIVETo analyze the fungal composition in Massa Medicata Fermentata based on culture dependent method and independent PCR-SSCP technique.

METHODFungi were directly isolated from Massa Medicata Fermentata samples. The obtained strains were identified according to morphology and DNA sequence. Meanwhile the total fungal DNA was extracted from Massa Medicata Fermentata samples, the cultural independent PCR-SSCP technique based on β-tubulin gene were used to identify the mycobiota.

RESULTAccording to cultural method, Aspergillus flavus and Rhizopus oryzae were present in Massa Medicata Fermentata samples, while A. flavus and A. niger were present in fried Massa Medicata Fermentata samples. In contrast, 5 species were obtained by PCR-SSCP technique, A. flavus was overlapped with fungal taxa derived from culture dependent method; A. ambiguu and A. s ivoriensis were dominant with relative abundance of 57% and 35% respectively, while the relative abundance of A. flavus was as low as 4%. None species was obtained from fried Massa Medicata Fermentata samples.

CONCLUSIONPCR-SSCP based on β-tubulin gene could distinguish fungi into species, culture dependent method combined with culture independent method could better understand the fungal composition associated with Massa Medicata Fermentata fermentation.

To prepare PLGA fiber scaffolds by electrospinning process and investigate the influence of preparation parameters on the structure of the scaffolds. With the compound of THF and DMF as the solvent, the PLGA fiber scaffolds with different surface morphology were fabricated via altering PLGA solution concentration, flowing rate and applied electric field strength. The morphology and diameter of the fibers were observed using a scanning electron microscope (SEM). The biocompatibility of cell-scaffold complex was also evaluated by seeding human dermal fibroblasts onto the PLGA fiber scaffolds, including cell adhesion and proliferation. The results show that the diameter of fibers and the bound of distributing increase with the increase in the concentration of PLGA solution. As the flowing rate increases, the diameter of fibers increases. However, with the increase in the applied electric field strength, no significant difference in the diameter of the fiber can be observed. Furthermore, both the increase in the concentration of PLGA solution and applied electric field strength in the volume range of current investigation can lead to the reduction in the beads formation within the scaffold. The results of in vitro cell culture on the PLGA scaffolds also confirm that the PLGA fiber can support the adhesion and proliferation of huaman dermal fibroblasts.

Synthetic biology research methods which design and build a new artificial biological systems (medicinal plants or microorganisms system) with specific physiological functions through clarifying and simulating the basic law of the biosynthesis of active components of traditional Chinese medicine, is considered to be a potential method to produce an abundant resources of bioactive components. Tanshinones is a kind of diterpene quinone compounds with important pharmacological activities from traditional Chinese medicine Salvia miltiorrhiza. This article systematically introduced the research progress of the synthetic biology of S. miltiorrhiza, in order to provide references for studies on other terpenoid bioactive components of traditional Chinese medicines, and give new research strategies for the sustainable development of traditional Chinese medicine resources.

OBJECTIVETo investigate the effects of dopamine (DA) and metabolite in striatum of Parkinson's disease (PD) rats treated by bone mesenchymal stem cells (MSCs) modified by plasmid pIRESneo-EGFP-BDNF.

METHODpIRESneo-EGFP-BDNF was transfected to MSCs with electroporation. The rat models of PD were set up by 6-OHDA and then divided into four groups randomly, which were Sham group, PD group, BDNF group. The rotating behavior of rat models induced by apomorphine (APO) intraperitoneally which transplanting bone MSCs or MSCs modified by plasmid pIRESneo-EGFP-BDNF through cerebral lateral ventricle after 2, 4 and 8 weeks. The levels of DA, homovanillic acid (HVA), dihydroxy-phenylacetic acid (DOPAC) were measured by high performance liquid chromatography (HPLC) in striatum of each group.

RESULTSThe rotation numbers (r/min) of MSCs group or BDNF group in the 2nd, 4th and 8th week after transplanting were significantly decreased compared with that of PD group (P < 0.05). Those of BDNF group were specially significant compared with those of MSCs group (P < 0.05). The levels of DA, HVA, DOPAC and the ratios of DA/HVA, DA/DOPAC in stratum after PD rats intervened by transplanting cells through cerebral lateral ventricle after eight weeks were increased significantly in BDNF group or MSCs group while compared with PD group, especially in BDNF group.

CONCLUSIONThe behavior of rat with PD was improved significantly by increasing the levels of DA and decreasing metabolic rate of DA in striatum while transplanting BDNF modified bone MSCs through cerebral lateral ventricle.

AIMTo investigate the antiepileptic effect of dizocilpine (MK-801) on amygdala kindling models in rats and the effects of its combination with general antiepileptic drugs.

METHODSTo establish amygdala kindling models in rats and observe the effect of dizocilpine on kindling models and its combination with general antiepileptic drugs (phenobarbital, valproate and nicardipine) at ineffective dose. The influence of dizocilpine on convulsions induced by semicarbazide (SCZ) in mice were also observed.

RESULTSDizocilpine (0.1-0.25 mg.kg-1, i.p.) was shown to dose-dependently inhibit amygdala kindled seizure, shorten the after discharge duration (ADD) and reduce the Racine's stage (P < 0.01). The combination of dizocilpine with phenobarbital, valproate, nicardipine at ineffective dose shortened ADD or reduced Racine's stages (P < 0.01). Dizocilpine (0.1-0.25 mg.kg-1, i.p.) significantly prolonged the latency and reduced the rate of convulsions and death in mice.

CONCLUSIONDizocilpine inhibits the seizure of the amygdala kindling and improve the antiepileptic activity of phenobarbital, valproate and nicardipine, indicating that these combination may provide a new approach for treating epilepsy.

OBJECTIVETo investigate the expression of forkhead box M1 (FOXM1) and its correlation with clinicopathological features and prognosis in patients with non-small cell lung cancer (NSCLC).

METHODSThe expression of FOXM1 in 68 cases of NSCLC was detected by immunohistochemistry. The FOXM1 expression in 6 tumor tissues (3 cases with negative and 3 cases with positive expression of FOXM1) was analyzed by Western blotting to confirm the immunohistochemical results. The correlation of the expression of FOXM1 with clinicopathalogical features and overall survival of the NSCLC patients was analyzed.

RESULTSThe expression of FOXM1 protein was detected in the nuclei or cytoplasms of the tumor cells. The positive expression rate of FOXM1 was 36.8% (25/68). Western blotting confirmed the immunohistochemical results. The expression level of FOXM1 in advanced stage cancer was significantly higher than that in early stage NSCLC (P = 0.001). The median OS was 23.0 months in patients with negative expression of FOXM1 and 13.0 months in those with positive expression (P = 0.001). Univariate analysis revealed that histological grade, lymph nodes status, TNM stage and FOXM1 expression were significantly associated with prognosis in the NSCLC patients (P < 0.05). The Cox multivariate analysis demonstrated that lymph nodes status, TNM stage and FOXM1 expression were independent poor prognostic factors (P < 0.05).

CONCLUSIONThe expression status of FOXM1 in NSCLC is an independent prognostic factor and negatively correlated with prognosis.
