Objective: To observe the effect of Haobie Yangyin Ruanjian Decoction (HYRD) on rats with hepatic fibrosis induced by CCl4 composited factor. Methods: Wistar rats were randomly divided into seven groups: control group, model group, HYRD groups of low, medium, and high doses, positive groups of Fufang Biejia Rungan Tablets, and colchicin. Model of hepatic fibrosis was induced by CCl4 composited factor. Malondialdehyde (MDA), total protein (TP), albumin (ALB) in serum and hydroxyproline (Hyp) in liver were detected by chromatometry; MMP-2 and MMP-9 activities in liver were detected by gelatin zymography; α-SMA expression in liver was evaluated by immunohistochemical method. Results: MDA in serum and Hyp in liver were decreased gradually in HYRD groups compared with those of model group; TP and ALB in serum were increased gradually in HYRD groups compared with those of model group; MMP-2 activity in liver was decreased in HYRD groups compared with those of model group; MMP9 activity had no significant change in each group and α-SMA expression was decreased gradually in HYRD groups compared with those of model group. Conclusion: HYRD can antagonize the hepatic fibrosis induced by CCl4 composited factor.

Objective: To explore the antifibrotic effect of echinacoside on carbon tetrachloride (CCl4)-induced hepatic fibrosis in rats. Methods: Male Wistar rats were randomly divided into normal control (n = 8), model (n = 14), and echinacoside treatment (n = 14) groups. The hepatic fibrosis model was induced by CCl4 compositor. The rats were ig administered with echinacoside at a daily dose of 50 mg/kg. The anti-oxidant status, liver function parameters, and hepatic hydroxyproline content were detected by chromatometry. The serum levels of hyaluronic acid (HA), type IV collagen (CIV), type III precollagen (PIIIP), and laminin (LN) were assayed with radioimmunoassay. The hpatic injury was detected by haematoxylin-eosine staining. The deposition of collagen was observed with Masson staining. Results: Echinacoside increased the superoxide dismutase activity and reduced the levels of malondialdehyde, aspartate aminotransferase, alanine aminotransferase, HA, CIV, PIIIP, and LN in serum. Echinacoside could also reduce the hydroxyproline content in liver, alleviate hepatic injury, and inhibit collagen deposition. Conclusion: Echinacoside possesses antihepatic fibrosis effect. © 2013 Tianjin Press of Chinese Herbal Medicines.

Objective To investigate the value of single photon emission computed tomography (CT) imaging and transmis‐sion CT imaging (microSPECT‐CT ) bremsstrahlung imaging for the solid tumor mesenchymal implantaion of 32 P‐chromic phos‐phate‐paclitaxel‐poly‐L‐lactic acid (32 P‐CP‐PSP‐PLLA) sustained release seeds and to investigate the 32 P in vivo biodistribution and degradation sustained release churacteristics .Methods The animal model of prostate cancer subcutaneously transplanted tumor was established .32 P‐CP‐PSP‐PLLA sustained‐release seeds were intratumorally implanted by the mediation of microSPECT‐CT brems‐strahlung imaging and the 32 P distribution in bearing tumor mouse was verified by the imaging and biological distrubtion tests .The ultrastructural changes of 32 P seeds were observed by the scanning electron microscope .Results The MicroSPECT/CT brems‐strahlung imaging could effectively guide the intratumoral implantation operation of the 32 P sustained‐release seeds with clear visu‐alization .Partial sustained‐release 32 P was remained in the tumor tissues with little distribution in important organs of spleen and liver ,which was proved by the biodistribution results .The particle surface and inside micropores and tunnels formation ,their pro‐gressive increase ,fusion and connection were found by the electronic microscope after the 32 P sustained‐release seeds intratumoral implantation .Conclusion The MicroSPECT/CT bremsstrahlung imaging can effectively monitor the 32 P sustained‐release seeds and their in vivo biodistribution and lays a foundation for the sustained‐release seeds prostatic targeted implantation .

ObjectiveTo investigate the alteration of behavior,such as spontaneous movement,spatial memory ability and cholinergic M receptors in the brain of mice subjected to chronic mild stress (CMS). And to determine whether Ningshen Ling (NSL)and dehydroepiandrosterone(DHEA)could reverse the cognitive impairment in this model.MethodsForty mice were divided into four groups: control group,CMS group,CMS+NSL(p.o.5g·kg-1·d-1) group and CMS+DHEA (i.p.5 mg·kg-1·d-1) group. Morris water maze procedure was used to determine the spatial memory ability. M receptor binding activity was measured with radioactivity assay by3 H-QNB.ResultsAfter 3 weeks CMS,the mice exerted a decrease in spontaneous movement test,and the latency in Morris water maze was obviously prolonged. Treating CMS mice with NSL and DHEA for 1 weeks could improve the spontaneous movement and latency declined. Whereas the3 H-QNB binding ability to M receptor showed a significantly decrease in cerebral cortex and hippocampus of CMS mice (P<0.05),the decreased ability of M receptor binding was reversed by NSL treatment in hippocampus(P<0.05).ConclusionNSL and DHEA can alleviate the stress response and reversed cognitive impairment induced by CMS,and it may be concerned with the central cholinergic M receptors activity.

OBJECTIVETo explore the correlation between electronic bronchus mirror and Chinese medical syndrome typing of Mycoplasma pneumonia children.

METHODSTotally 198 Mycoplasma pneumonia children inpatients were assigned to three syndrome types according to Chinese medical syndrome typing and self-formulated typing standards of electronic bronchus mirror, i.e., Fei-qi accumulation of damp and heat syndrome, Fei-qi accumulation of toxicity and heat syndrome, deficient vital qi leading to lingering of pathogen syndrome. The correlation between electronic bronchus mirror and Chinese medical syndrome typing was explored.

RESULTSAs for comparison between electronic bronchus mirror and Chinese medical syndrome typing, Kappa value (K^) was 0.645 and Spearman coefficient correlation (r) was 0.653 (P < 0.01) for Fei-qi accumulation of damp and heat syndrome; K^ was 0.724 and r(s) was 0.727 (P < 0.01) for Fei-qi accumulation of toxicity and heat syndrome; K^ was 0.506 and r(s) was 0.515 (P < 0.01) for deficient vital qi leading to lingering of pathogen syndrome.

CONCLUSIONChinese medical syndrome typing of Mycoplasma pneumonia children was moderately in line with inspection typing under electronic bronchoscope with significant correlation.

ObjectiveTo assess the clinical efficacy and safety of donepezil in treating the mild to moderate cognitive impairment of vascular dementia.Methods60 patients with vascular dementia were randomly divided into therapy group (donepezil 5 mg/d for 4 weeks, and then increased to 10 mg/d) and control group (piracetan 800 mg,3/d). All patients were assessed with Mini Mental State Examination (MMSE), Wechsler Adult Intelligence Revised in China (WAIS-RC), Activities of daily living (ADL), and Clinical Global Impression (CGI), before and 12 weeks after treatment. ResultsMMSE scores improved significantly in both groups after the treatment. The therapy group produced significantly better scores than the control groups on the MMSE(P<0.05). WAIS-RC scores improved significantly in the therapy groups(P<0.01), but there was no significant difference for control groups(P>0.05), before and after treatment. Severity Improvement(SI) score of ADL and CGI in the both groups decreased. The total efficiencies of donepezil and piracetan groups were 86% and 56% respectively. There was no significant difference in adverse effects between two groups. ConclusionDonepezil can improve the cognitive function of patients with vascular dementia, which seems better than that of piracetan, and it is fairly safe for vascular dementia patients to take donepezil 10 mg a day.

Incision of the spinal cord (myelotomy) after spinal cord injury (SCI) is a surgical treatment which is mainly performed within 24 hours after SCI. However, many patients are fi rst seen outside the established time window of 24 hours. Furthermore, little attention has been given to its effi cacy and mechanism after 24 hours. In this study, dorsal longitudinal incision of spinal cord on SCI rats was performed at 72 hours after SCI to remove the liquefi ed necrotic gray matter. The results indicated that after myelotomy, locomotor function of hindlimbs signifi cantly improved from 21st day after SCI. There was also increased residual white matter area at the rostral and caudal segments to the injury center when examined at day 42 after the injury. These results suggested that myelotomy at 72 hours after injury has protective effect on the spinal cord.

Objective To assess the prognostic value of tumor burden measured by 18F-fluorodeoxy glucose-positron emission tomography ( FDG PET) imaging for stage Ⅲ NSCLC). Methods Fifty-six patients with lung cancer were analyzed, to whom staging PET-CT scans before treatment concurrent chemoradiotherapy and 2-year follow-up were performed. , Relationship between overall survival (OS) and metabolic tumor volume (MTV) and maximum standardized uptake value (SUVmax) were determined.Results The estimated median OS for the cohort were 14. 5 months. Kaplan-Meier analysis showed that MTV had a significant effect on OS (x2 =5.42 ,P =0. 014). No significant relationship was found between SUVmax and OS ( x2 = 0. 74, P = 0. 391 ). According to multivariate Cox regression analysis, MTV and SUVmax wereassociatedwithincreaseddeath ( x2 = 5.54, P = 0.019; x2 = 4.47, P = 0.031 ). Conclusions This study shows that higher tumor burden assessed by PET MTV is an independent unfavorable prognostic factor in lung cancer, MTV is valuable for predicting overall survival and could be a prognostic factor.
