Forty-three cases of malignant tumors with metastases to serous cavites were treated by interventional chemotherapy under ultrasound guidance and monitoring. 43 cases (83 injections) were all successfully operated and followed up. After peritoneoclysis, besides the common side effects of chemotherapyie nausea and vomiting, 3. 8% of the patients had abdominal pain and 75. 5% had abdominal distention. No complication of hemorrhage, infection, drug leakage or organ injury oceurred. It is suggested the method is safe easily to be used especially for the intracavitary chemotherapy of malignaant tumors and deserves to be widely employed.

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.

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.

Chinese prescription is composed of Chinese herbal medicines according to "seven compatible relations" and "sovereign, minister, assistant and courier" principles. There are many methods in the research on combination and composition of Chinese herbal medicines. These methods are classified into traditional model and modern model. For the time being, compatibility study of traditional Chinese herbal medicines has developed from traditional model to modern model. The traditional model mainly studies the effects and mechanisms of the whole and split formulae in medical crude drug level, while the modern model mainly studies the effects and mechanisms of Chinese herbal medicine compositions in components combination level. Moreover, quantitative analysis becomes probable by modern model method. Now, setting up of new components combination model and optimal composition methods will not only develop the combination and the composition of Chinese herbal medicines from medicinal crude drug level to components composition level, but also get new formulae which have clear components and effects, and action targets and mechanisms. It will effectively promote the development of Chinese medicine formula.

The elderly patients with diabetes often have a high prevalence of hypertension.Meanwhile,hypertension is a major vascular risk factor in this population.The benefit of proper management of hypertension in elderly patients with diabetes has been well recognized.According to the IDF Global Guideline for Managing Old People with Type 2 Diabetes,lifestyle interventions are recommended to form the first step in managing hypertension in elderly patients with diabetes.Pharmacological therapy should be initiated in addition to lifestyle interventions after 6 weeks during which non-pharmacological therapy has failed to achieve blood pressure targets.ACE-inhibitors are the first choice for initial medication,especially in the presence of diabetic nephropathy.ARBs can be used in people who cannot tolerate ACE-inhibitors.Diuretics or calcium channel blockers can be used as the first add-on therapy to ACE-inhibitors or ARBs if they fail to achieve target blood pressure.β-blockers should be considered for combination therapy in people with tachycardia or coronary artery disease.The generally recommended blood pressure target for older people with diabetes should be less than 140/90 mmHg(1 mmHg=0.133 kPa).

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.

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.
