0.05),the relative bioavailability of the capsules was(95.43?15.47)%.CONCLUSION:2preparations were bioequivalent.

OBJECTIVE To evaluate the effect of air disinfection methods to improve air quality in dental clinic.METHODS Electrostatic attraction method was used to disinfect air in dental clinic.Air samples here collected before,during and after daily and treatments compared.Bacterial colonies were counted. The air effect of disinfection was compared with undisinfected control group in terms of total number of germs.RESULTS Bacterial count of disinfected group was lower than that of undisinfected group(P

Objective To examine the relationship between inflammatory response induced by cardiopulmonary bypass and postoperative cognitive dysfunction.Methods Twenty-five patients undergoing elective cardiac valve replacement under cardiopulmonary bypass were randomly divided into two groups:ulinastatin group(group U,n=13) and control group(group C,n=12).In group U,ulinastatin 12 000 U/kg Was given intravenously immediately after induction of anesthesia,6 000 U/kg ulinastatin Was added to the priming solution,and 6000 U/kg ulinastatin was given at 5 min before the aortic decamping.In group C,normal saline was given instead of ulinastatin.Venous blood samples were taken after induction of anesthesia,at the end of CPB,and 24 h after operation for determination of plasma IL-6 concentration and neutrophils NF-kB expression.The cognitive function of the patients was evaluated by Mini-Mental State Examination(MMSE) before and 3 d,7 d after operation.Results The concentraion of IL-6 and neutrophils NF-kB expression were lower in group U than in group C(P<0.05 or 0.01).There wag no significant difference in the incidence of postoperative cognitive dysfunction between group C and U.Conclusion Inflammatory response induced by cardiopulmonary bypass is not related to postoperative cognitive dysfunction.

Objective: To evaluate the effects of lotensin on sympathetic responses following cervical plexus block and to explore the mechanism of cardiovascular responses and sympathetic nervous system activity according to plasma catecholamine concentration. Method: Sixty adult patients were randomly divided into two groups (n = 30):Group A and group B. In group B lotensin 0.15mg/kg was taken orally at night before surgery and 2h before anesthesia separately. Hemodynamics was determined before anesthesia(T_1), 5min(T_2), 10min(T_3), 15-20min(T_4)and 30min (T_5) after cervical plexus block. For measurement of plasma catecholamine concentration, blood was collected at T_1,T_3,T_4 and T_5. The study was finished before beginning of surgery and infusion. Result: In group A after anesthesia SP,DP, MAP,HR,RPP and plasma noradrenalinc level rose markedly(P0.05). All parameters were lower in group B compared with group A(P

Objective: To evaluate Raven's Standard Progressive Matrices (RSPM) for assessing validity of test performance. Methods: To compare the results of RSPM between head injured patients with and without malingering. Results:①There were significant differences in the performance between the two groups of patients in subtests A,B,C and D of RSPM. There was no significant difference on subtest E. ②Based on p

Objective:To study the validity of Binomial Forced-Choice Digit Memory Test(BFDMT) in detecting dissimulation of intellectual deficit.Methods:64 subjects with compensable head injury were assessed by BFDMT,experiential judgment and Raven's Standard Progressive Matrices (RSPM),and were finally diagnosed on intellectual deficit degrees.Results:(1)The rate of malingering was 78.1% judged by BFDMT,and 43.8% by experiential judgment.(2)All of the 16 uncertain cases by experiential judgment were assessed as malingering by BFDMT.(3)Only one case in 64 was considered as a faulted diagnosis by follow-up.Conclusion:BFDMT is useful for detecting dissimulation of intellectual deficit particularly for the difficul cases in clinical experiential judgment.

Objective To observe the effects of Tangnaikang on interleukin 6 (IL-6) and minor necrosis factor-α(TNF-α) levels of Diabetic KKAy mice. Methods After diabetic KKAy mice were treated with Tangnaikang for 8 weeks,FBG was determined by glucose test-paper, IL-6 and TNF-αconcentratious in serum and adipocytes were determined by ELISA. Results IL-6 and TNF-α levels were reduced in serum and adipocytes of KKAy mice. Conclusion Tangnaikang can significantly reduce the levels of IL-6 and TNF-α in Diabetic KKAy mice, and the reduction of them can help to decrease FBG level.

Objective To investigate and compare the effect of cyclosporine A (CsA) vs. tacrolimus (TAC)-based immunosuppressive regimen on chronic allograft nephropathy. Methods Ninety-six patients who received a cadeveric kidney transplantation in our unit during Jan. 1995 to Jan. 2004 more than 12 months prior to study enrollment and who were being treated with CsA-based immunosuppressive treatment were included. All patients received allograft biopsy and were diagnosed as CAN. Patients were differentiated according to following regimen. Patients were either converted to tacrolimus (TAC group, n=58) or remained on their initial CsA-based immunosuppression (CsA group, n=39). The clinical data at study entry and after 3, 6 and 12 months including serum total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), high density lipoprotein (HDL), blood urea nitrogen (BUN), creatinine (SCr), albumin were recorded during a follow-up of over 12 months. Results Though TC, TG and LDL levels remained unchanged in CsA group, while statistically reduced in TAC group respectively ( 6.60? 1.34 mmol/L vs. 5.20? 0.75 mmol/L, 3.00? 1.40 mmol/L vs. 1.90? 0.86 mmol/L, and 3.70? 0.93 mmol/L vs. 3.00? 0.72 mmol/L, P

Subcutaneous injection of 1.0 mg/kg cadmium chloride in 0.8% solution was given to rabbits weighing 1.7~2.5kg 3 times a week for 10 weeks.An equal volume of normal saline was injected to the rabbits of the control group.Blood specimen from the auricle vein and 24-hour-urine of every rabbit were collected once a week.Ten weeks later the renal cortex of the rabbits WES resected,processed routinely and examined under optical microscopy,The level of guanidinoacetic acid (GAA) of the serum and urine was determined with HPLC.It was found that the serum level of GAA increased after 3 weeks of cadmium administration while urinary excretion of GAA increased slightly in the first week and decreased significantly in the second week of cadmium injection and thereafter.

The changes of the activities of serum CK,LDH,HBKH and AST of 11 soldiers having stayed in simulated 3500m and 4500m were observed.It was found that the activities were significantly increased in the order of CK,LDH and HBDH because of hypoxia but the changes of AST was of no statistical significance.CK/LDH ratio and pulse rate showed similar charges to serum enzymes but the changes of arterial oxygen saturation and working efficiency were the opposite to those of serum enzymes.These findings suggest that serum CK and LDH are the indicators of choice to evaluate human reactions to high altitude.
