Objective: To observe the clinical efficacy of warm needling combined with iontophoresis of Chinese medicine for temporomandibular joint disorder (TMD). ＜br> Methods: A total of 100 TMD cases were randomly allocated into a treatment group and a control group, 50 in each group. Cases in the treatment group were treated with warm needling combined with iontophoresis of Chinese medicine, whereas cases in the control group were treated with Western medication. The therapeutic efficacies in two groups were assessed after three courses of treatment. ＜br> Results: The recovery rate and total effective rate were 54.0% and 98.0% respectively in the treatment group, versus 30.0% and 82.0% in the control group, showing significant differences (bothP＜0.05). The recovery rates in the treatment group were higher than those in the control group respectively after 1, 2 and 3 courses of treatment, indicating that warm needling combined iontophoresis of Chinese medicine could substantially shorten the course of treatment. ＜br> Conclusion: Warm needling combined with iontophoresis of Chinese medicine is remarkably effective for TMD and deserves further clinical application.

The effects of DMSO and nifedipine on experimental myocardial infarction induced by isoproterenol(ISP)were investigated.The results showed a significant reduction in myocardial FFA and MDA contents in DMSO and nifedipine-treated groups, as compared with the ischemic group, and a beneficial effect on activity of SOD,GSH-px and Ca~(2+)-Mg~(2+)-ATPase. The effects of OH. and Ca~(2+) in myocardialg infarction were further analysed in this study.

AIM: To observe the pathologic changes in lung and the role of p38 MAPKinase signal pathways in pulmonary alteration in diabetic rats. METHODS: Diabetic rats were induced by intraperitoneally injected streptozotozin (STZ). After 4 weeks,we observed the pathologic changes in lungs,tested protein kinase C (PKC) activities by isotope in lungs of model rats,tested transforming growth factor (TGF-?_1) by Western blotting and immunohistochemical analysis,and determined the expression of p38 MAPKinase mRNA using in situ hybridization.RESULTS: After STZ administration for 4 weeks,we observed thickened pulmonary capillary basal lamina and increased number of fibre in Diabetes mellitus (DM) rats. TGF-?_1 levels,PKC and p38 MAPK activities were also found increased. CONCLUSION: The increased activities of TGF-?_1 and p38 MAPK suggeste that TGF-?_1 may play an important role in diabetic lung,and hyperglycemia-PKC-p38 MAPK signal pathways may be involved in the pathogenesis of diabetes.

Objective To study the effect of Toll-like receptor 4(TLR4)on the expression of IRF-3 and IFN-β during the inflammatory reaction induced by cerebral ischemia reperfusion in mice.Methods Totally 144 mice were randomly divided into 3 groups:(1)ischemia reperfusion group(I group):the mice were subjected to 12 minutes ischemia by bilateral common carotid arteries(CCA)occlusion,and reperfusion without additional intervention;(2)TLR4 blocking group(T group):after 10 minutes of bilateral CCA occlusion,TLR4 antibody was injected slowly into right CCA within 2 minutes;(3)sham group(S group):no CCA occlusion was performed.At 1,2,3 and 4 d after ischemia reperfusion,the expression levels of TLR4,IRF-3 and IFN-β protein in the cortex was respectively examined by Western blot.Results In the right cortex,the expression levels of TLR4,IRF-3 and IFN-β of I group were distinctly higher than that of S and T gtoup(P<0.05);the expression levels of the 3 protein of T group were significantly higher than those of S group(P<0.05).Conclusion The cerebral ischemia reperfusion could activate TLR4 expression in the cortex of the mice.TLR4 might participate in the cerebral ischemia reperfusion through upregulating the expression of IRF-3 and IFN-β.

Objective To discuss the techniques of ventricular endoscopy for obstructive hydrocephalus.Methods A total of 33 patients with obstructive hydrocephalus were treated by ventriculostomy using ventricular endoscopy from June 2003 to December 2006.The patients had received CT,MRI,and 99mTc-DTPA cistern SPECT before the surgery.Results Endoscopic third ventriculostomy was performed successfully in 32 patients,the other patient died of hemorrhage under the third ventricle fistula.Postoperative fever occurred in 13 patients.One patient developed bilateral chronic subdural hematoma 6 months after the operation,and was cured by drill and drainage.Three patients developed subdural hydroma 6 months postoperation without showing symptoms.They were monitored without any treatment.The 32 patients were followed up for 2-42 months(mean,16.7 months),all of them achieved clinical relieve.In the patients,the intracranial pressure(ICP) was 26(16-39) cm H2O before the operation,and was significantly decreased to 22(12-28) cm H2O 7 days after the operation(t=2.903,0.005

Objective To investigate the effects of Topiramate(TPM) on activity of SOD and concentration of MDA in blood serum and the changes of the nerve function scores after cerebral ischemia/perfusion in rats. Methods Male Sprague-Dawley rats were randomly divided into ischemia/perfusion group, TPM group and sham-operation group. Rat models of transient focal cerebral ischemia were made by 2 h occlusion of right middle cerebral artery occlusion and reperfusion for 24 h.Rats in TPM group were injected TPM(8 mg/ml,80 mg/kg)in the beginning of the artery occlusion and the reperfusion. The rats were sacrificed after they were evaluated by the nerve function deficiency scores. The activity of SOD and concentration of MDA in blood serum were measured.Results The activity of SOD and concentration of MDA in blood serum in ischemia/perfusion group were (157.72?19.04)U/ml and (7.45?0.84 )nmol/ml, those in TPM group were ( 171.25?15.72)U/ml and (( 6.10?0.98) nmol/ml,those in sham-operation group were (179.74?7.95)U/ml and (5.90?0.72 )nmol/ml. Compaired with sham-operation and TPM groups, the activity of SOD in ischemia/perfusion group was significantly lower, the concentration of MDA was obviously higher (all P

Objective To investigate the neuroprotective effects of Topiramate (TPM) on rat brain with ischemia-reperfusion damage and its mechanisms.Methods The 30 male SD rats were randomly assigned to sham operated group, ischemia-reperfusion group and TPM treated group.The cerebral ischamia and reperfusion model was made by suture occlusion of right middle cerebral artery(MCAO).Rats in TPM treated group were intraperitoneally injected TPM (80 mg/kg) twice. At 24 h following onset of MCAO,the nerve function score was evaluated with Neurological Grading Scale. The infarction volume was measured with TTC staining. The contents of glutamate (Glu) and gamma-aminobutyric acid (GABA) of cerebral cortex were tested by the high performance liquid chromatography with fluorescent detection. GABAA receptors were observed by immunohistochemistry.Results (1) Compared with the ischemia-reperfusion group, the Neurological Grading Scale of TPM treated group was significantly higher(P

Objective To explore the protection effects of the reduced form of nicotinamide-adenine denucleotid(NADH) on cardiac fibroblasts apoptosis induced by hydrazine in vitro.Methods Cardiac fibroblasts isolated from neonate rats were divided into four groups.In NADH pretreatment before hydrazine treatment group,the cardiac fibroblasts were cultured first in the medium containing 400?g/ml NADH for 2 hours,and then cultured in the medium containing 400?g/ml NADH plus 2mmol/L hydrazine for 72 hours;in hydrazine treatment group,the cardiac fibroblasts were cultured first in normal medium containing 400?g/ml NADH for 2 hours and then cultured in the medium containing 2mmol/L hydrazine for 72 hours;in control group,the cardiac fibroblasts were cultured only in normal medium for 72 hours;and in NADH pretreatment control group,the cardiac fibroblasts were cultured in medium containing 400?g/ml NADH for 72 hours.After the treatments mentioned above,the changes in nuclear of apoptotic cardiac fibroblasts as stained by Hoechst33258 were observed under fluorescence microscope,the apoptotic and necrosis rates of cardiac fibroblasts stained by AnnexinⅤ/PI were assayed by flow cytometry,the mitochondria membrane potential of cells stained by rhodamine123 was also assayed by flow cytometry.Results Hydrazine could induce apoptosis of the cardiac fibroblasts.After NADH pretreatment,the number of apoptotic cardiac fibroblasts with pyknosis of nuclear was lowered,the rates of apoptosis and necrosis decreased,and the mitochondria membrane potential of cells was elevated.Conclusion NADH pretreatment could reduce the apoptosis induced by hydrazine by improving the function of mitochondria.
