Aim To investigate the effect of the GABAA receptor on the analgesia,hypnosis and amnesia induced by GABA in mice.Methods GABA was intracerebroventricularly(icv) injected and securinine,a GABAA receptor antagonist,was intravenously(iv) injected after the GABA intracerebroventricularly injection.Then four techniques including hot-plate test,acetic acid-induced writhing test,awaken test as well as step-through test & step-down test were employed to evaluate the effects on the pain index in hot-plate test(HPPI),the writhing times,the sleeping time(ST) and the latency & the number of errors.Results GABA increased the HPPI and ST,but decreased writhing times and the latency & increased the number of errors in conscious mice;the above effects are dose-dependent.Securinine could antagonize the effects stimulated by GABA.Conclusion GABA lead to analgesia,hypnosis and amnesia.GABAA receptor might be the important target for these effects.

Objective To report two cases of familial Gitelman syndrome and literature review regarding the updates of relevant genes,classification,treatment,and prognosis.Methods The clinical data of two sisters with Gitelman syndrome were retrospectively analyzed.Results Their blood pressures were within normal range.Hypokalaemic alkalosis,hypomagnesemia,and hypocalciuria were corrected almost completely after three days of intravenous magnesium and potassium infusion,spirolactone and indometacin.However,the maintenance of normal potassium was unsuccessful over one year.Conclusion Hypokalaemic alkalosis,hypomagnesemia,and hypocalciuria were normalized in Gitelman syndrome.There was some debate in regard to using PGE2 synthetase inhibitors.Tolerance of long-term medication will be the big challenge for curative effect.

OBJECTIVETo investigate the regulation of Cha Gan Beng Ga on the activity of biomarker PGC-1α in vivo and in vitro, and lay the foundation for studying the efficacy result of Cha Gan Beng Ga on xenograft tumor model and extracting active constituents.
METHOD(1) The coarse powder of Cha Gan Beng Ga was extracted with 70% ethanol solution through heating and refluxing, and finally was used to freeze dry powder. (2) 50 mg x kg(-1) of freeze-dried power was orally administrated to KM and C57BL/6J mice once daily, lasting for 5 consecutive days; different concentrations of extracted materials was given to non-small cell lung cells A549. (3) The expression level of PGC-1α mRNA was quantitatively determined in lung tissue of mice and non-small cell lung cells A549.
RESULTThe expression levels of PGC-1α in lung tissue of different mice strains had an increasing tendency. Furthermore, the expression levels of PGC-1α in non-small cell lung cells A549 also had an increasing tendency, showing dose and time-dependent relationships.
CONCLUSIONMongolian Medicine Cha Gan Beng Ga could induce the over-expression of PGC-1α mRNA in lung tissue of mice and in non-small cell lung cells A549. The present results will lay foundation for studying the efficacy result of antitumor and active constitutes in future.

Objective To establish a new processing method for gait data on Matlab to evaluate the hindlimbs behavior of non-human primates. Methods Gait analysis was tested on three rhesus monkeys 6 weeks after spinal cord injury, and kinematics data of hindlimbs were obtained using the VICON system. The raw data of kinematics were filtered and extracted, which were achieved through VICON 3D motion capture system with the Excel link combining Matlab with Microsoft Excel, and calculated in the Matlab environment. Results The kinematic parameters such as step length, step height, knee joint angle, and malleolus joint angle were gained by calculating. The mean values of step length (F=2.869, P=0.088) and step height (F=1.148, P=0.344) showed no significant difference at three speeds, which implied a higher repeatability of the data model. Angle-time curve reflected the joint function and movement. This system initially described the foot gait trajectory which could be used in gait repetitive analysis, and also generated the gait 2D/3D trajectories of hindlimbs. Conclusion The implement of these functions makes the post-processing of data more flexible and open whitout VICON system, and the calculated parameters and space tracing of gait trajectory basically meet the need of hindlimb behavior evaluation for nonhuman primate.

Objective RNPC1 may act as an oncogene or suppressor gene in human tumors and its role in human renal cell carcinoma (RCC) remains unclear.The objective of this study was to investigate the role of RNPC1 in the development of RCC.Methods Over-expression of RNPC1 gene group (RNPC1 group) and short hairpin RNA interfering RNPC1 gene expression (shRNPC1 group) were respectively built in RCC CAKI-1 and CAKI-2.The blank control group (NC group) and negative control group (SCR group) were built as well.The qRT-PCR and western blot (WB) were used to detect the expression levels of RNPC1 mRNA and RNPC1 protein in RCC cells.Lentivirus infection was applied to establish stable expressed RCC cell lines of RNPC1 over-expression and interference.Detection was made on mRNA and protein expression levels in RNPC1 stable RCC cell lines.The effects of RNPC1 on cell proliferation, colony formation assay, migration, and invasion were detected by CCK-8 cell differentiation test, clone test, scratch test, and migration and invasion test.WB was applied to detect the change of protein expression in the EMT path of RNPC1 stable RCC cell lines and explore the molecular mechanism of RNPC1 effect on the biological function of RCC cells.Results The expression levels of RNPC1 mRNA and protein were found lower in shRNPC1 group than those in SCR group, while the expression levels of RNPC1 mRNA and protein in SCR group were higher than those NC group (P<0.05).The capability of proliferation in shRNPC1 group was stronger than that in SCR group, while the capability of proliferation in shRNPC1 group was weaker than that in NC group (P<0.05).The capabilities of cell migration and invasion were stronger in shRNPC1 group than those in SCR group, while the capabilities of cell migration and invasion in RNPC1 group were weaker than those in NC group (P<0.05).RNPC1 could inhibit the proliferation capability of RCC cells and might up-regulate the protein expression of E-cadherin and down-regulate the protein expression of β-catenin and vimentin, thus inhibiting EMT path and the capabilities of migration and invasion off RCC cells (P<0.05).Conclusion RNPC1 acts as a tumor suppressor in RCC and has the potential for the prediction of RCC prognosis.
