ObjectiveTo observe the effect of electroacupuncture at Neiguan (PC6) and Shenmen (HT7) on heart rate variability (HRV) in patients with post-cerebral-infarction sequelae.MethodEighty patients were randomized into two groups, 40 cases in each group. The control group was intervened by anti-platelet aggregation and other ordinary symptomatic treatment based on Western medicine, while the treatment group was by electroacupuncture at Neiguan and Shenmen in addition to the treatments given to the control group.ResultThere were no significant differences in comparing the HRV indexes between the two groups before intervention (P>0.05); while the HRV indexes in the treatment group were superior to that in the control group after intervention (P<0.05). HRV indexes were improved after intervention in the treatment group (P<0.05); of the indexes, only SDNN was improved after intervention in the control group (P<0.05), and the rest indexes were insignificantly changed (P>0.05).Conclusion Electroacupuncture at Neiguan and Shenmen can significantly reduce HRV in patients with post-cerebral infarction sequelae.

Background and purpose:MicroRNAs are endogenous small RNAs and involved in target gene regulation in post-transcription level. As a tumor suppressor, microRNA-335 (miR-335) was participated in the occurrence and progression in many types of human tumors. This study aimed at investigating whether miR-335 can regulate cell migration and invasion by negative targeting Rho associated coiled-coil forming protein kinase (ROCK1) in human osteosarcoma cell line MG-63.Methods:The speciifc binding ability of miR-335 to ROCK1 3’-untranslated region (UTR) was theoretically predicted and detected by the luciferase reporter gene assay. Western blot and real-time PCR were used to evaluate the effect of miR-335 on the expression of ROCK1 at protein and mRNA levels. Cell migration and invasion assays were performed by transwell chambers in MG-63 cells intervened by over-expression of miR-335 and knockdown of ROCK1.Results:Luciferase reporter gene assay showed that miR-335 could target ROCK1 3’-UTR. Lower miR-335 but higher ROCK1 was expressed in MG-63 cells. The results of Western blot showed that ROCK1 protein expression was decreased by transfection of miR-335 mimic or siROCK1. Transwell chambers results showed decreased cells invading through the substrate membrane after over-expression of miR-335 or knockdown ofROCK1 gene.Conclusion:miR-335 inhibits the migration and invasion ability of MG-63 human osteosarcoma cell line, which may through targeting ROCK1 3’-UTR and subsequent down-regulating ROCK1 expression.

Objective To investigate the expression and correlation of microRNA‐335(miR‐335) and ROCK1 in osteosarco‐ma tissue and osteosarcoma cell lines MG‐63 and U2‐OS .Methods Eighteen paired tissue specimens of osteosarcoma and matched normal tissue were chosen clinically .Two osteosarcoma cell lines MG‐63 and U2‐OS were chosen as experimental group while the human osteoblast cell line hFOB 1 .19 as control group ,Quantitative real‐time PCR were used to evaluate the different expression of miR‐335 and ROCK1 mRNA in osteosarcoma tissue and cell lines;miR‐335 mimic was transfected into MG‐63 and U2‐OS ,while Quantitative real‐time PCR and Western blot were used to evaluate the effect of over‐expressed miR‐335 on ROCK1 mRNA and protein level .Results The result of real‐time PCR indicated a special lower expression of miR‐335 but higher ROCK1 ,and the cor‐relation between miR‐335 and ROCK1 was negative .Western blot showed that miR‐335 could decrease ROCK1 protein expression . miR‐335 mRNA showed a hyper‐expression while lower ROCK1 mRNA and protein after transfection of miR‐335 mimic .Conclusion The expression of miR‐335 and ROCK1 shows a negative correlation in both tissue and cell level;over‐expression of miR‐335 can decrease ROCK1 expression .

Objective To clone, express and purify human PIF1 protein and analyze its ATPase activity. Methods The PIF1 cDNA was amplified by PCR from HeLa cell cDNA library and inserted to pET24b with histidine tag at its terminus to form pET24b-PIF1 plasmid. The recombinant pET24b-PIF1 plasmid was transformed to RosettaTM 2 (DE3) and the expression of PIF1 protein was monitored by SDS-PAGE analysis. By using fast protein liquid chromatograph (FPLC) system, the PIF1 protein was purified by affinity chromatograph and gel filtration. The ATPase activity of PIF1 was checked by thin layer chromatograph(TLC). Results The PIF1 protein was successfully cloned and expressed in E.coli. Conclusions The purification procedure of PIF1 protein was established using FPLC. The overexpressed and the purified PIF1 helicase has DNA and Mg2+ dependent ATPase activity.

Objective] To explore the treatment of Lanshi Micang disease with tumors related diagnosis and treatment method, in order to have a more comprehensive understanding of anal fistula, so as to broaden the mind, improve the clinical efficacy. [Method] FromLanshi Micang-Anal Fistulaof eight prescriptions for treatment of hemorrhoids and analysis, on the basis of combining the characteristics of compatibility with tumors inDongyuan effect testand the specific prescription, made analysis of anal fistula, diagnosis and treatment of anal fistula for the study of LI Dongyuan thought. [Results] LI Dongyuan from dampness, heat, wind, dryness four on the treatment of anal fistula, with angelica, Gentiana and blood dryness of medicine, to Shufeng pain, Xinrun and blood on regulation of syndrome treatment, paid attention to diet to restore the anal fistula. [Conclusion] LI DongyuanLanshi Micangis rich in content, the treatment of anal fistula has experience, as of today, the diagnosis and treatment on anorectal diseases of clinical thought still has important guiding significance.

SCI-E and SSCI covered papers on psychiatry published from 2002 to 2011 by authors of China, USA and Japan were analyzed using bibliometrics and the number, relative impact power and international cooperation of these papers were compared among the 3 countries, which showed that both the number and impact power of SCI-E and SSCI covered papers on psychiatry published by authors of China increased, the number of papers published by authors of China was catching up with that published by authors of Japan, and the impact power of papers published by authors of China was higher than that published by authors of Japan.However, they were significantly lower than those published by authors of USA.It is quite important to publish papers in journals with a high academic level and to strengthen international cooperation for increasing the domestic scientific research level in psychiatry.
