AIM: To study the effects of taurine on ATP sensitive potassium channel (IK_~-ATP ) during hypoxia in single ventricular myocyte. METHODS: The model of myocardial hypoxia was induced by unmixed and saturated nitrogen. IK_~-ATP activities were measured by whole-cell patch clamp recording. RESULTS: Activities of IK_~-ATP in the cell membrane of hypoxia ventricular myocyte significantly increased, compared to that in the normal. Extracellular injection of taurine (5,10,20 mmol/L) inhibited the increase in the IK_~-ATP activity in the hypoxia myocardium in a concentration-depend manner. Injection of taurine also recovered shorten APD during hypoxia. CONCLUSIONS: Taurine produces its cardioprotective effect by inhibiting the activity of IK_~-ATP in the hypoxia cardiomycytes of guinea pig. The results suggest that the depletion of taurine during myocardial hypoxia contributes to the early activation of the K_~ATP channel. [

To explore the audiological features in children who were sever sensorineural hearing loss infected with rubella virus. There were two cases of rubella virus infection in children who were deaf, they conducted the distortion product otoacoustic emission, ABR and auditory steady-state evoked response (ASSR) examination, then analyzed the results comprehensively. Two patients' mothers were prompted to have infected rubella virus during the early three months pregnant period by history and laboratory tests. The two patients were not detected deafness gene mutation. Audiology results implied the two patients were very severe binaural sensorineural deafness, so they were recommended to equipped with hearing aids and cochlear implant surgery. Early pregnancy women infected with rubella virus can cause very severe offspring sensorineural deafness. The crowd whose mother were suspected to infect with rubella virus in early pregnancy, that should be tracked and detected hearing in order to achieve early detection, early intervention and early treatment.

Acupuncture therapy for regaining consciousness activates soreness, numbness, distention, heaviness, radiating and moving, electric shock and ant climbing sensations at the specific acupoints in the stroke patients. Radiating and moving sensations are the summary of needling sensations such as soreness, numbness and twitching presenting during lifting and thrusting manipulation. These sensations are the essential factors of the therapeutic effect of regaining consciousness. Radiating sensation refers to the conduction along meridians and radiation of soreness and numbness. Moving sensation refers to the local muscular twitching at acupoints and the involuntary movement of limbs, joints and the distal. Acupuncture at the specific acupoints achieves radiating and moving sensations for promoting the circulation in meridians, regulating qi and mind and balancing yin and yang in stroke patients. This therapy was introduced in the paper in view of acupoint location, needle insertion and manipulation.

Background Oxidative stress is a major mechanism underlying the pathogenesis of cardiovascular disease. It can trigger inflammatory cascades which are primarily mediated via nuclear factor-κB (NF-κB). The NF-κB transcription factor family includes several subunits (p50, p52, p65, c-Rel, and Rel B) that respond to myocardial ischemia. It has been proved that persistent myocyte NF-κB p65 activation in heart failure exacerbates cardiac remodeling. Mechods A recombinant adeno-associated virus serotype 9 carrying enhanced green fluorescent protein and anti-NF-κB p65 ribozyme (AAV9-R65-CMV-eGFP) was constructed. The cells were assessed by MTT assay, Annexin V–propidium iodide dual staining to study apoptosis. The expression of P65 and P50 were assessed by Western blot to investigate the under-lying molecular mechanisms. Results After stimulation with H2O2 for 6 h, H9c2 cells viability decreased significantly, a large fraction of cells underwent apoptosis. We observed a rescue of H9c2 cells from H2O2-induced apoptosis in pretreatment with AAV9-R65-CMV-eGFP. Moreover, AAV9-R65-CMV-eGFP decreased H2O2-induced P65 expression. Conclusions AAV9-R65-CMV-eGFP protects H9c2 cells from oxidative stress induced apoptosis through down-regulation of P65 expression. These observations indicate that AAV9-R65-CMV-eGFP has the potential to exert cardioprotective effects against oxidative stress, which might be of great importance to clinical efficacy for cardiovascular disease.

[Objective] To detect the expression levels of connexin43(Cx43),P-gp and COX-2 in bone marrow of patients with acute leukemia (AL),and investigate their relationship with the pathogenesis,prognosis and resistance of this condition.[Methods]Using SYBR green real-time quantitativereverse transcription polymerase chain reaction (SYBR-RT-PCR),the expression of Cx43,P-gp and COX-2 mRNA were detected in 77 AL patients at different phases,including 36 initially-treated,20 complete-remission (CR)and 20 relapsed.A follow-up was done in those initially lreated.[Results]Expression levels of Cx43,P-gp and COX-2 mRNA from initially-treated were 0.52±0.57,1.42 ±1.06,1.14±0.95;those from relapse AL patients were 0.20±0.40,2.29 ±1.11,1.69±0.81,respectively,those from CR patients were 0.95±0.37,0.93±-0.73,0.79±0.58,respectively,those from normal patients were 1.16 ±0.67,0.86±0.63,0.61±0.57.Expression levels of Cx43 mRNA in initially-treated and relapse AL patients were significantly lower than those in normal patients and CR patients(initially-treated P were 0.001,0.005;relapse patients were P＜0.001),while the comparison between normal patients and CR patients showed no statistical significance(P=0.185).Cx43mRNA expression level was negatively correlated with P-gp and COX-2 mRNA,and a negative correlation was noted of both two expressions in initially-treated and relapse groups (Cx43 mRNA and P-gp mRNA r were -0.471,-0.362,-0.526;Cx43 mRNA and COX-2 mRNA r were -0.479,-0.344,-0.471).A follow-up of four months was conducted in 36 initially-treated patients,eight of them died.The expression Cx43 in those who died was lower than that who survived.The difference was significant(t=2.16,P=0.042).[Conclusion] Cx43mRNA expression levels of initially-treated and relapse AL patients were lower than those in normal patients and CR patients,P-gp and COX-2 mRNA expression levels of initially-treated and relapse AL patients were higher than those in normal patients and CR patients.Cx43 expre-ssion probably is a favorable prognostic factor.Cx43 is participation in the genesis,development and drug resistance of AL.
