Two hundred male and 200 female patients with type 2 diabetes mellitus admitted from January 2007 to April 2008 were enrolled in the study. Of them, 267 were diagnosed as non-alcoholic fatty liver disease (NAFLD) by ultrasonography. The measurements included:body mass index (BMI) ,waist-to-hip ratio (WHR) ,fasting blood glucose( FBG), ALT, AST, total bilirubin(TBIL), cholesterol(CHO),triglyceride(TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol ( LDL-C) ,serum creatinine (Cr), supersensitive C-reactive protein (hsCRP) and urine albumin/creatinine. The relationship of above factors with NAFLD was determined. Our data showed that male NAFLD patients were in general younger than female. The BMI ( t = 11. 361, P = 0. 000), waist circumference ( t = 9. 771, P =0. 000), hip circumference (t = 10. 469, P =0. 000) ,TG(t =7. 352, P =0. 000) and hsCRP (t =2. 242,P =0. 026) of NAFLD patients were significantly higher than those without NAFLD. The hsCRP of patients with central obesity was also significantly higher than those without central obesity (t = 0. 266, P = 0. 045 ).BMI and TG were positively correlated with NAFLD. Waist circumference was an independent factor of NAFLD in male patients, same as hip circumference with NAFLD in female patients. In conclusion, gender,central obesity and dyslipidemia may be risk factors for NAFLD in patients with type 2 diabetes mellitus.

Objective To observe the effect of insulin glargine plus mefformin on inflammatory factors(IF) in the treatment of patients with newly diagnosed type 2 diabetes(T2DM).Methods 110 patients with newly diagnosed T2DM were given insulin glargine(beginning dose:10 U/d) and mefformin(0.5 g,tid) for 12 weeks;while 100 cases selected for the same period from the normal healthy population were taken as control group.Baseline fasting blood glucose(FPG),2 h postprandial blood glucose(2 hPG),glycosylated hemoglobin (HbA_1c),C-reactive protein(CRP),TNF-α and IL-6 were observed.Results Before treatment,FPG,2 hPG,HbA_1c and IF in T2DM group were obviously higher than those in control group(P＜0.05),but there was no difference in other clinical data (P＞0.05).After 12 weeks treatment,in T2DM group there was a significant improvement in blood glucose targets [FPG from (14.8±3.9) mmol/L to (6.6±2.1) mmoL/L;2 hPG from (17.6±3.3) mmol/L to (8.3±1.2)mmol/L;HbA1c from (9.6±2.7)% to (6.5±0.8)%,t=7.40,8.37,3.98,P＜0.05],and the level of IF also decreased significantly [CRP from (8.8±2.5) mg/L to (5.5±1.4) mg/L;TNFα from (2.9±0.6) ng/L to (1.6±0.2) ng/L;IL-6 from(170.3±22.2) pg/L to (105.9±14.6) pg/L,t=4.61,3.52,5.68,P＜0.05].Conclusions Insulin glargine and mefformin combined therapy can improve glucose metabolism in patients with newly diagnosed T2DM,and decrease the levels of IF.

T-lymphoblastic lymphoma (T-LBL) is a rare form of non-Hodgkin lymphoma (NHL),which is biologically similar to T-acute lymphoblastic leukemia(ALL),and occurs most frequently in childhood and adolescence.T-LBL progresses fast.The treatment of LBL with conventional chemotherapy regimens for NHL has shown relatively low rates of complete remission and of disease-free survival.Now,it is reasonable to treat patients with LBL with the current ALL-type protocols,and hematopoietic stem cell transplantation may yield a more favorable overall survival (OS) in T-LBL patients,especial in relapsed or refractory LBL patients.

Objective To investigate the effect of low-intensity ultrasound on intraocular hypertension and its mechanicsm.Methods The intraocular hypertension rabbits were treated with ultrasound.The intraocular pressure(IOP),trabecular meshwork HE staining,EM microscopy,extracellular matrix through immunohistochemistry were performed.Results After treatment,IOP was descended and trabecula interspace was wider than the control eye.The expression of collagen I,laminin and fibronectin was inhibited.Conclusion Low-intensity ultrasound can decrease IOP.It may be related with the change of histologic structure of trabecular meshwork.

Objective: To investigate the correlation of serum adiponectin and hepatic adiponectin receptor (adipoR) expression with pathological changes of the liver in the rats with non-alcoholic fatty liver diseases (NAFLD). Methods: The NAFLD model was induced by an oral administration of high fat diet. The rats were sacrificed at 2, 4, 8, and 12 weeks. ELISA was used to measure the serum adiponectin and other biochemical parameters. The liver index was also examined. AdipoR mRNA expression in the liver were measured by RT-PCR. Liver slices were observed with Sudan III staining, H-E staining and Masson staining for pathological changes. Results: The serum adiponectin in the model group were gradually decreased during the 2nd, 4th 8th and 12th week, and were all significantly lower than those in the control group at corresponding time points (P<0.01). Serum adiponectin level was found negatively correlated with the liver index (r=-0.383, P=0.015) hepatic inflammation scale (r= 0.475, P=0.002), and hepatic fibrosis scale (r=-0.353, P=0.025). The hepatic adipoR1 mRNA expression in the model group was gradually increased (P<0.01 from the 4th week) and adipoR2 mRNA expression was gradually decreased compared with the control group (P<0.01 from the 2nd week). AdipoR2 mRNA expression was negative correlated with liver index(r=-0.431, P=0.006) and hepatic fibrosis scale (r=-0.353, P=0.025). Conclusion: The hepatic adipoR mRNA expression is abnormal in rats with NAFLD; the serum adiponectin level is decreased and negatively correlated with liver inflammation and fibrosis scale, indicating that the decreased serum adiponectin level, pathological hepatic adipoR expression, especially the decreased AdipoR2 expression in the liver may be related to the pathogenesis of NAFLD.

Aim To explore the modulation of Salvia miltiorrhiza on hyperpolarization-activated current (Ih) channels in dorsal root ganglion (DRG) neurons of rats and identify the mechanism of Salvia miltiorrhiza in alleviating pain and inhibiting calcium overload. Methods The effect of Salvia miltiorrhiza injection on Ih channels in DRG neurons of rats were examined by using whole-cell patch clamp technique. Results The experimental results showed that the amplitude of Ih evoked by -150 mV was (-1.06±0.18) nA. The Ih could be fitted well into the single kinetics and the time constant of activation, τ was clearly voltage-dependent with τ=(322.14±28.81) ms at -100 mV, decreasing to τ=(62.51±9.78) ms at -150 mV. The reversal potential of Ih was (-35.03±1.12) mV measured from tail currents. But no significant differences were found between the DRG neurons in the absence and presence of Salvia miltiorrhiza injection (10%, 25%, 50%) in the current amplitude, the time constant of activation and the reversal potential. The only difference between the DRG neurons in the absence and presence of Salvia miltiorrhiza injection was the half-activation potential of Ih. In control recordings the half-activation potential was (-106.07±3.59) mV. By comparison, the half-activation potentials changed to (-111.59±3.79) mV (n=31 neurons, P＜0.05), (-119.37±4.96) mV (n=31 neurons, P＜0.05) and (-121.23±3.86) mV (n=31 neurons, P＜0.05) in the presence of 10%, 25%, 50% Salvia miltiorrhiza injection, respectively. Conclusion Only the half-activation potential of Ih in the arthritic and neuropathic rat models shifted in the depolarizing direction, which increased the electrophysiological activity of Ih and made it related to peripheral hyperalgesia. The selective inhibition of Salvia miltiorrhiza on the electrophysiological activity of Ih may be one of the mechanisms underlying its analgesic effects.

BACKGROUND: There has been no definite cause for Bell's palsy. Different kinds of causes and courses always lead to different outcomes. Up to now there has not been to accord on the relationship between assessment of facial muscle function and prognosis of Bell's palsy.OBJECTIVE: To explore the relationship between level diagnosis, blink reflex(BR) , electroneurography(ENoG) and prognosis in order to find the timing for treatment of Bell's palsy.DESIGN: A self-control study.SETTING: Department of otolaryngology, Beihai People's Hospital,Guangxi Zhuang Autonomous Region.PARTICIPANTS: There were 42 cases of Bell's palsy that were in accordance with the diagnosis criteria and hospitalized in the Beihai People's Hospital from January 1989 to December 1999. Thirty-six cases out of the 42 were well documented and thus were studied here.METHODS: Level diagnosis, BR and EnoG test as well as facial muscle assessment were conducted on thirty-six patients with Bell's palsy.RESULTS: Patients with facial function score under 11 and with the lesion at D segment had poor results in BR and ENoG test. The outcome of conservative treatment for these patients was also bad. That would be improved by facial nerve decompression. The results of examination within one month after palsy onset were correlated with prognosis ( P ＞ 0. 05) . Two cases received decompression on the 40th day onset and recovered completely. Two cases Received decompression in the 2nd month, one recovered completely and decompression and recovered partially.CONCLUSION: Patients with the following manifestations may make conplete recovery after conservative treatment: lesion distal to segment D, facial function over 11 marks, presence of R1 wave by BR test in the 1st month and fiber deprivation ＜ 90% by ENoG. Facial nerve decompression should be taken for patients in a condition other than that.

Objective To investigate whether there are different effects of electric stimulation of vagus nerve,peripheral nerve(sciatic nerve and trigeminal nerve),and motor cortex on pentylenetetrazol (PTZ)induced convulsion in rats.Methods The vagus nerve and sciatic nerve were exposed in rats.The stimulation electrodes were placed on the vagus nerve,sciatic nerve,trigeminal nerve,and motor cortex,respectively.After electric stimulation,PTZ(50 mg/kg)was intraperitoneally injected into the rats.The pattern and latency of the convulsion seizure were observed and recorded.Results Racine's grade Ⅰ-Ⅴ grade convulsion seizure Was present in 9 rats(9/10)in the control group after the injection of PTZ.However,this intensity Was reduced to Ⅰ-Ⅲ grade differentially in all the rats by electric stimulation of the vagus nerve(5/10)or peripheral nerve(6/10 and 5/10).Furthermore,in the group of rats stimulated at motor cortex,there Was completely no convulsion.On the other hand,when pathological changes appeared in cortex or hippocampus(i.e.epileptic model was set up by 7 weeks stimulation),the same stimulation of motor cortex was not able to inhibit the convulsion seizure induced by injection of PTZ and all these rats showed Ⅳ-Ⅴ grade seizure(10/10).Conclusions In physiological condition,all of the four types of stimulation differentially reduced intensity of convulsion seizure triggered by PIZ injection and motor cortex stimulation has the best effect.However.when rats were in pathological status and epileptic nidus appeared in their brains.stimulatiion of motor cortex has no effect on PTZ induced convulsion seizure.
