Objective: To evaluate the relation between preoperative anxiety and pain threshold in patients with hysteromyoma, and to investigate the effect of anxiety on postoperative analgesia. Methods: Fifty patients with hysteromyoma were included and evaluated the anxiety level with the Self-Rating Anxiety Scale (SAS) 1 day before hysterectomy. Threshold of heat pain and cold pain of all patients were also assessed by quantitative sensory testing (QST) at the same time. All patients received hysterectomy under the combined spinal epidural anesthesia,and 2 mg morphine were injected to their epidural spaces 10 min before the end of surgery. Visual analgesia scores (VAS, 0～10) were performed to evaluate the level of pain at 0 h, 2 h, 6 h and 12 h after the operation. The time of first ambulation after operation were also recorded to help assess the effect of postoperative analgesia. Results:The average SAS scores of all these 50 patients was (48.7±10.3) . And 13 cases (26%) were with mild anxiety (SAS=50-59), whereas 5 cases (10%) were with moderate or severe anxiety (SAS≥60) . The threshold of heat pain and cold pain were (37.8±3.1)℃ and (15.8±3.6)℃.VAS at all investigated time points was 0,(1.4±1.1), (3.3±1.6) and (4.4±2.1) . There was significantly negative correlation between the SAS scores and the pain threshold of all patients with anxiety (r=-0.67, -0.56; Ps<0.001). But for these patients, the correlations between the SAS scores and VAS scores at 6h and 12h after the operation were positive (r=0.48,0.55, Ps<0.001) . Furthermore, the average time of first ambulation after operation in those anxious patients was later than that in the patients with no anxiety (SAS<50) [(46.6±7.1) h vs.(39.8±9.3) h, P <0.05].Conclusion: The higher level of preoperative anxiety in patients with hysteromyoma is correlated to higher level ofpain threshold, less effect of analgesia and longer time to recovery. It indicates that it is necessary to assess preoper-ative anxiety in patients with hysteromyoma.

Objective To study the angiographic characteristics of coronary heart disease(CHD) in CHD patients with type 2 diabetes mellitus.Methods Analysis was carried out in terms of blood chemistry test result and angiographic data in 454 patients who received selective coronary angiography.Results Compared with the simple CHD patients without type 2 diabetes mellitus,CHD patients with type 2 diabetes mellitus showed higher blood triglyceride(TG) level and lower apoA level.Their coronary angiography showed more four-branch(17.3% vs 9.5%,P

Objective To evaluate the effect of remifentanil preconditioning on hepatic ischemiarepeffusion (I/R) injury in rats with liver cirrhosis.Methods Healthy male Sprague-Dawley rats,weighing 160180 g,received 40％ tetrachloride carbon 3 ml/kg (in peanut oil) intragastrically twice a week for 8 weeks to induce liver cirrhosis.Thirty-five rats with liver cirrhosis were randomly divided into 5 groups (n =7 each) using a random number table:sham operation group (group S),group I/R,and preconditioning with different does of remifentanil groups (R1,R2 and R3 groups).Hepatic I/R injury was induced by clamping the branches of hepatic artery,portal vein and common bile duct in the left and median hepatic lobes for 30 min followed by 90 min reperfusion in anesthetized rats with liver cirrhosis.In R1,R2 and R3 groups,remifentanil was infused intravenously at 0.4,2.0 and 10.0 μg· kg-1· min-1 for 15 min,respectively,and the rats were exposed to ischemia for 30 min followed by 30 reperfusion starting from 10 min after infusion was stopped.At 90 min of reperfusion,blood samples were collected from the abdominal aorta for determination of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities.The rats were then sacrificed and livers were removed for determination of superoxide dismutase (SOD) activity,malondialdehyde (MDA) content,and expression of activated caspase-3 (using immunohistochemistry and Western blot analysis) and for detection of cell apoptosis in hepatic tissues.Apoptotic index was calculated.Results Compared with group S,the serum ALT and AST activities,MDA content and apoptotic index were significantly increased,SOD activity was decreased,and the expression of activated caspase-3 was up-regulated in I/R,R1,R2 and R3 groups.Compared with group I/R,no significant changes were found in the indexes mentioned above in group I/R,and the serum ALT and AST activities,MDA coment and apoptotic index were significantly decreased,SOD activity was increased,and the expression of activated caspase-3 was down-regulated in R2 and R3 groups.Conclusion Remifentanil preconditioning can reduce hepatic I/R injury in rats with liver cirrhosis,and the mechanism is related to inhibition of the lipid peroxidation and cell apoptosis.

ObjectiveTo evaluate the efffects dexamethasone (DEX) administration at different times on intestinal ischemia-reperfusion(I/R) injury and inducible nitric oxide synthase(iNOS) activity in mice.Methods Tirty-five healthy male Kunming mice weighing 20-24 g were randomly divided into 5 groups( n =7 each): Sham operation group (group Ⅰ ); intestinal I/R group (group Ⅱ ); DEX administration before ischemia group (group Ⅲ ); DEX administration during ischemia group ( group Ⅳ) and DEX administration at the begining of reperfusion group (group Ⅴ ).Intestinal I/R injury was induced by clamping the superior mesenteric artery for 30 min.Normal saline10 mg/kg,DEX 10 mg/kg was injected iv at 30 min before ischemia in groups Ⅱ and Ⅲ respectively.DEX 10 mg/kg was injected iv at 5 min of ischemia in groupⅣ and immediately at the begining of reperfusion in group Ⅴ.The mice were sacrificed at 3 h of reperfusion,and then the small intestinal tissues were taken for determination of intestinal pathological score( Chiu score),iNOS activity and nitric oxide (NO) content.ResultsChiu score was significantly higher in groups Ⅱ - Ⅴ,and iNOS activity and NO content were sinificantly higher in groups Ⅱ,Ⅳ and Ⅴ than in group Ⅰ ( P ＜ 0.05).Chiu score,iNOS activity and NO content were sinificantly lower in group Ⅲ,and were higher in group Ⅴ than in group Ⅱ ( P ＜ 0.05).There was no significant difference in the indexes mentioned above between groups Ⅱ and Ⅳ ( P ＞ 0.05).ConclusionDEX administration before ischemia can reduce intestinal I/R injury by inhibiting iNOS activity; DEX administration during ischemia has no effcet on intestinal I/R injury and iNOS activity; DEX administration at the begining of reperfusion aggravates intestinal I/R injury by enhancing iNOS activity.

AIM and METHODS: A study of radioimmunoimaging was carried out on Kcnming mice - uterine cervical cancer (U14) using 99mTc labeled monoclonal Au14-1 with a modified Schwartaz method. RESULTS: The bio - distribution showed that radioactivity accumulated in tumor tissue at 12h after 99mTc - Au14- 1 injection in tail vein. The uptake by tumor was 4. 12 % ID/g at 2h and 8. 79 % ID/g at 24h respectively. The tumor/non - tumor (T/NT) radiocativity ratios for organs except kidneys were ranged from 2.02 to 6.71 at 24h post - injection. The image of tumor showed at 12h and clearer at 24h after injection. CONCLUSION: The quality of tumor image was relevant to the T/NT radioactivity ratios. It was demonstrated that 99mTc- Au14-1 has a good capability of localization for tumor.

Objective To investigate the correlation between BMI and insulin dose in diabetic patients after short-term continuous subcutaneous insulin infusion (CSII). Methods Three hundred patients with type 2 diabetes mellitus (T2DM) were enrolled and randomized into the normal weight (BMI < 23 kg/m2) group, overweight (BMI 23 ~ 25 kg/m2) group and obesity (BMI≥25 kg/m2) group. The metabolic and anthropometric parameters of each group were compared and the related factors which may influence insulin dose were analyzed. Results The insulin dose per weight in the overweight group or in the obesity groups was significantly lower than that in the normal weight group. Weight and BMI were negatively correlated with the insulin dose per weigh. Conclusions Differences of glycemia level , β-cell function and insulin resistance exist in Chinese type 2 diabetes patients with different BMI. The stratification of BMI should be considered before estimating the insulin dose by body weight in CSII therapy.

OBJECTIVETo investigate the metabolic profile of hydrocortisone-induced 'Kidney-yang deficiency syndrome'in rats and the intervention effects of Morinda officinalis.

METHODProton nuclear magnetic resonance (1H-NMR) technique was used to analyze the rat metabonome in serum. Orthogonal partial least squares discriminant analysis (OPLS-DA) were processed to analyze the metabonome difference between the control and hydrocortisone treated samples. Twelve potential biomarkers were selected, via the parameter of variable importance in the projection (VIP). Principal components analysis (PCA) was employed to process the data from the M. officinalis. treatment group and the intervention effects of M. officinalis, was investigated through the selected potential biomarkers.

RESULTAfter hydrocortisone treatment, the energy metabolism, amino acids metabolism and gut microflora environment were seriously disturbed and transmethylation was surpressed. M. officinalis could effectively alleviate the disturbance of energy and amino acids metabolism and enhance transmethylation, but could not modulate the gut microflora environment.

CONCLUSIONThe results obtained suggested that metabonomic studies could better reflect the whole status of metabolism in bio-systems, and could be treated as a potential powerful approach in pharmacological studies and investigation of the essence of 'syndrome' in traditional Chinese medicine.
