Introduction: Many new objective tests to assess the function of specific structures of the vestibular organ are currently adopted in vestibular clinics. One of the objective assessments include the video head impulse test (vHIT) where gain & velocity responses of eye relative to the head movements are recorded using an infrared camera. Methods: Thirty normal hearing subjects age between 18 to 25 years old participated in this study. At least ten Lateral, Left Anterior Right Posterior (LARP), and Right Anterior Left Posterior (RALP) responses were recorded for each participant by making small and rapid unpredictable head movements. Results: The average velocity gain for Lateral responses at 40 ms, 60 ms and 80 ms were 1.05 ± 0.003, 1.03 ± 0.002 and 1.01 ± 0.003 respectively. The LARP average velocity regression were 1.01 ± 0.24 for Left Anterior and 1.05 ± 0.25 for Right Posterior, with an average gain asymmetry of 5.13%. The RALP average velocity regression were 1.08 ± 0.31 for Right Anterior and 1.12 ± 0.30 for Left Posterior, with an average gain asymmetry of 5.87%. One sample T-test were conducted to compare Lateral responses to a previous study by Mossman et al. (2015) where significant differences in velocity gain at 60 ms and 80 ms between studies were found where, t (59) = 5.56, p <0.01 and t (59) = 2.86, p < 0.01 respectively. Conclusion: This indicates the importance of establishing on-site norms for every clinical settings as techniques used and equipment differences could affect the results.

Aframomum melegueta (Zingiberaceae) seeds are used in West Africa, as a remedy for variety of ailments such as stomach ache, snakebite, diarrhea and anti-inflammatory properties. The hypoglycaemic effects of crude leaf extract of Aframomum melegueta on the treatment of alloxan induced diabetes in male rats and non-diabetic rats (control) were examined in this study. Results obtained from the experiment showed that the elevated blood glucose level caused by oral administration of 250 mg / kg body weight of alloxan was reduced significantly (p < 0.01) by oral administration of Aframomum melegueta leaf extract doses of 50, 100 and 200 mg/kg with the exception of 20 mg/kg when compared to control groups. The non-diabetic groups that received the extract showed reduction in blood sugar level as the dose increases when compared to their control group. There was a final weight gain and organ restoration for both the diabetic and non-diabetic rats after treatment when compared with their controls. This study showed that the extract have hypoglycemic and prophylactic effects.

This study was carried out to evaluate environmental factors at Ha Nam General Hospital. The result showed that: about 640 kg of solid waste is generated everyday of which 22% is toxic. The equipments and infrastructure are under ability for treating this waste. Almost of the microclimatic parameters are in the normal value, but the illumination is a little low. The physical and chemical parameters in supplied water at the hospital are within the permitted standard. The hospital need to equip tools and equipment for collecting, transportation and treatment this waste according to the standards of Viet Nam Ministry of Health, standard waste bins

A study of environmental sanitation in Bac Ninh General Hospital was carried out in 2004 with certain objects: 145 patients and their relatives, 37 people living near the hospital, 35 health workers, and 5 managers of the hospital… The hospital delivered about 1570 kg of waste daily; 340 kg of them was dangerous and must be treated in special way. The hospital implemented medical solid waste management and treatment well; the incinerator had worked effectively in making the hospital’s environment fresh. The medical solid waste treatment system of this hospital was a good sample

Hepatocellular carcinoma (HCC) is the second largest cause of cancer deaths worldwide.TLRs signal transduction pathways are related to the progress of HCC.As an innate immune recognition receptors on the surface of the cell,TLRs are involved in the ligand-mediated activation of various cells and the secretion of cytokines in liver through signal transduction,which is part of the cause and development of HCC.A better understanding of TLRs and these signaling pathways in the liver will help us understand the mechanism of hepatocarcinogenesis and provide a new therapeutic target for HCC.

Objective To introduce a new technique of one-stage auricular reconstruction by using the retroauricular fascial flap. Methods The retroauricular fascial flap was designed to cover a cartilage framework for auricular reconstruction. Results Seventeen cases who had injured over two years and received no surgical treatment, underwent auricular construction. In 3-month to 2-year follow-up, all patients obtained satisfactory appearance of the reconstructed ears that possess delicate structure and close color to adjacent skin. Conclusion For retroauricular fascial flap has adequate blood supply, it makes operating procedure simple and the occurrence rate of complication reduced. It is proven that this is a good method of auricular reconstruction.

Objective To investigate the differentiation of mesenchymal stem cells(rMSCs) of young rat into neuron-like cells with Ligustrazin hydrochloride. Methods rMSCs were separated from femurs marrow flushed out with DMEM(low glucose) by using a needle and syringe, then planted in plastic culture flask. Through expanded to 5 passages, rMSCs were induced to differentiate into neuron-like cells with Ligustrazin hydrochloride. Anti-neurofilament(NF-M), nestin, neuron-specific enolase(NSE), MAP-2,GAP-43 and glial fibrillary acidic protein(GFAP) antibodies were detected by immunohistochemistry. Results rMSCs were comprised a single phenotypic population and displayed a fibroblast-like morphology after 5 passage in culture. With 10*!?g/L bFGF pre-induce for 24*!h, then the medium was replaced with induction medium containing Ligustrazin hydrochloride. The induced-rMSCs exhibited neuronal morphological characteristics from the first half an hour to 5*!h. The neuron-like cells expressed NF-M, NSE, MAP-2,GAP-43 and nestin positive, but didn't express glial astrocyte marker GFAP.Conclusion rMSCs can be induced to differentiate into neuron like cells with Ligustrazin hydrochloride in vitro.

Objective To explore the electrophysiological characteristics and the expression of mRNA and protein of L-type calcium channel in rat bone mesenchymal stem cells(MSCs). Methods MSCs were isolated,cultured and purified.RT-PCR was used to detect the mRNA expression of ?1C,?1D,?1H,?1S.The protein expression of L-type calcium channel(?1C) was testified by immunohistochamical.Ion currents were recorded in MSCs using whole-cell patch clamp technques.Results CD29,CD44,CD106 expressed in about 93% MSCs and CD14,CD34,CD45 expressed negatively.A high expression of mRNA in ?1C was detected by RT-PCR but no expressions were observed in ?1D,?1G,?1H,?1S.Immunofluorescent double labeling showed an expression of ?1C subunits in MSCs.Moreover,inward currents were recorded in 16 of 36 cells using whole-cell patch clamp techniques.The currents were activated around-30?mV and peaked at 0 to 10?mV and were blocked by nifedipine(10??mol/L).These cells had larger currents with Ba~(2+)(10?mmol/L) in bath solution than with Ca~(2+)(2?mmol/L).Conclusion The results indicated that adult rat MSCs expresse functional L-type calcium channels.It is possible that this channel plays a role on the proliferation and differentiation of MSCs.
