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 To study the expression of Vascular Endothelial Growth Factor (VEGF),Malondialdehyde (MDA),Hypoxia Inducible Factor-1 α (HIF-1 α) in the Non-Steroidal Anti-Inflammatory Drug (NSAID)-associated gastric mucosa injury tissue,and to understand the mechanism of NSAID induced gastric mucosa injury.Methods We collected 114 biopsy specimen of gastric mucosa under endoscope from patients admitted to our hospital,including 70 cases with NSAID-associated chronic erosive gastritis or gastric ulcer (NSAID group) and 44 cases with chronic superficial gastritis who never take NSAID as controls (the control group).Immunohistochemistry technique was used to detect the positive expressions of VEGF,MDA,HIF-1α in patients.Results The positive rate of VEGF expression in the NSADI group was significantly lower than that in the normal control group (25.7％ (18/70) vs.54.5％ (24/44),x2 =9.70,P ＜ 0.05).The positive rates of MDA and HIF-1α in the NSADI group were significantly higher than these in the normal control group (MDA:62.9％ (44/70) vs.27.3％ (12/44),x2 =13.70,P ＜0.05; HIF-1α:45.7％ (32/70) vs.13.6％ (6/44),x2 =12.50,P ＜ 0.05).Conclusion NSAID drugs may induce gastric mucosa injury by decreasing the expression of VEGF and increase the levels of MDA and HIF1-α in gastric mucosa tissue.

Objectives To investigate the significance of electronic bronchoscopy and bronchoalveolar lavage in diagno-sis and treatment in children with pulmonary mass lesion. Methods A total of 74 hospitalized children from January 2011 to June 2012 whose imaging examinations showed massive patchy shadow were examined and treated by electronic bronchoscopy and bronchoalveolar lavage. Their clinical data were retrospectively analyzed. Results The major cause for the massive shadow was infection according to electronic bronchoscopy examination (68/74, 91.89%), 65 cases of them were lobar pneumonia, 3 cas-es were pulmonary tuberculosis followed by 5 cases of foreign body (6.76%) and one case of pneumorrhagia (1.35%).The lower left lung was the most frequently seen site of infection, followed by lower right lung. The agreement between infection sites and imaging examination was 97.30%. Bronchoalveolar lavage fluid showed that the primary pathogen of lobar pneumonia infection is Mycoplasma pneumoniae (MP) (42/65, 64.62%). The highest detection rate of MP was found in preschool group and the detec-tion rate between different age groups indicated statistically significant difference (P<0.01). The imaging examination showed pulmonary lesions in 61.54%children with lobar pneumonia improved significantly in one week. The improvement rate of pul-monary lesions was higher in infected children with short duration (1-2 weeks, 90.91%) between disease onset and electronic bronchoscopy inspection than those with longer duration (2-3 weeks, 51.72% and >3 weeks, 35.71%) (P<0.05). Conclusions Electronic bronchoscopy and bronchoalveolar lavage play dual roles in etiological diagnosis and therapy in children with pulmo-nary mass lesion.
