Chinese Journal of Tissue Engineering Research 2001;5(5):57-58
ObjectiveTo probe the alterated characteristic of reactive oxygen species, reduce glutathione and glutathione peroxidase (GSH - PX) in serum of persons. Method Under the controlled load by treadmill, correlative indexes were determined during resting state, sub - maximalload and exhaustive exercise. ResultROS level of serum increased significantly during sub- maximal load compaired with that of restingstate. The ROS level during exhaustive exercise was higher than that of sub - maximal load( P <0. 01 ) . GSH content and GSH - PX activity de-creased significantly( P <0. 001 ). GSH content and GSH - PX reactivity decreased significantly( P <0. 001 ) during sub - maxiaml load and in-creased after exhaustive exercise which was still lower that of resting state. Conclusion ROS increased with the enhancement of exercise intensityand the time. GSH and GSH - PX showed a significant decrease in content and activity respectively followed by apparent enhancement.

OBJECTIVE To study the usage of antibiotics in aseptic operation,and strengthen the management of antibiotics usage. METHODS We investgated the usage of antibiotics in aseptic operation retrospectively,then statistically analyzed. RESULTS Among all the 347 cases,343 cases were used for prophylaxis,the usage rate was 98.85%.The mean time of antibiotic therapy was 7.22 days.90.96% of the patients were treated with antibiotics for 3 days or more,53.35% of the patients were treated beyond 7 days.Ninety one patients were given antibiotics 0.5-2 hours before the operation(26.53%).There were 7 kinds of drugs used in the operation,the cephalosporin class accounted for 70.26%,moreover was third generation cephalosporin. CONCLUSIONS The prophylactic application of antibiotics in the aseptic surgery has some unreasonable phenomenon and must be strengthened.Training the doctor to use the antibiotics reasonably,and the effective surveillance management mechanism be established.

Objective To evaluate the effectiveness of EEG bispectral index (BIS) as the feedback control variable of target-controlled infusion (TCI) of propofol for sedation in patients undergoing laparoscopic hysterectomy under epidural anesthesia. Methods A total of 60 patients for selective operation of laparoscopic hysterectomy under epidural anesthesia were randomly divided into two groups: the feedback TCI group (FTCI) and the TCI group (TCI),with 30 patients in each group.The target blood concentration of propofol was set up at a level of 2 mg/L.It was maintained unchanged in the TCI group throughout the surgery.The BIS value,as the control variable,was set up at 70 in the FTCI group.The highest and lowest BIS values,mean arterial pressure (MAP) and HR during the operation,the standardized unit dose of propofol,time for orientation recovery,the degree of amnesia during the operation and patient's satisfaction were recorded and compared between the two groups. Results Of the two groups: the maximum of BIS values were 76 1?6 4 and 86 0?8 6,respectively,with statistically significant difference ( t = -5 058, P =0 000),and the minimal values were 69 0?4 5 and 60 9?11 8,respectively,with significant difference ( t =-3 513, P =0 000); the highest MAPs were (90 9?14 2) mm Hg and (100 4?11 6) mm Hg,respectively,with significant difference ( t =-2 838, P =0 006),and the lowest,(74 2?12 5) mm Hg and (63 8?13 8) mm Hg,respectively,with statistical significance ( t =-3 059, P = 0 003); the time for orientation recovery was (440 8?141 0)s and (576 4?120 5)s,respectively,with significant difference ( t = -4 004, P =0 000).Total dose of propofol in the FTCI group [(510 48?82 75)mg] was statistically lower than that in the TCI group [(620 65?76 79)mg; t =-5 345, P =0 000],the same was the standardized unit dose of propofol [FTCI: (5 08?1 26)mg,TCI:(6 02?0 86)mg; t =-3 375, P =0 001].No significant differences were seen between the two groups in the degree of amnesia during the operation and patient's satisfaction. Conclusions BIS is feasible to be used as a feedback control variable in propofol anesthesia.It offers less propofol consumption,appropriate sedation,rapid recovery of orientation and more stable blood pressure.

Objective To compare the effect of active compression-decompression cardiopulmonary resuscitation(ACD-CPR) with standard- cardiopulmonary resuscitation(S-CPR) on ventricular function in a canine ventricular fibrillation model. Methods Ventricular fibrillation was induced in anesthetized and instrumented canine. Twenty-four dogs were randomly assigned to either ACD-CPR group or S-CPR group.After 4 minutes of untreated VF,two-dimension echocardiography was used to evaluate the left ventricular end-diastolic volume(LVEDV),left ventricular end-systolic volume(LVESV) and left ventricular ejection fraction (LVEF) of every canine of the two groups when they were undergoing cardiopulmonary resuscitation. Results During ventricular fibrillation, both ACD-CPR group and S-CPR group showed decreased LVEDV compared with pre-ventricular fibrillation, but not statistically significant( P >0.05).LVEDV was increased in ACD-CPR group compared with S-CPR group, but not statistically significant (P> 0. 05). Both ACD-CPR group and S-CPR group showed significantly increased LVESV compared with pre-ventricular fibrillation,of which the difference was statistically significant ( P <0. 001). Both ACD-CPRgroup and S-CPR group showed significantly decreased LVEF compared with pre-ventricular fibrillation,of which the difference was statistically significant (P <0. 001). LVEF was increased in ACD-CPR group compared with S-CPR group,of which the difference was statistically significant ( P = 0.019). Conclusions Compared with S-CPR,ACD-CPR resulted in higher LVEF.

Objective To evaluate the role of interleukin-4 receptor (IL-4R) in renal fibrosis following renal ischemia-reperfusion (I/R) injury in mice.Methods Twelve male wild type BALB/C mice and 12 IL-4Rα gene-knockout mice,aged 8-10 weeks,weighing 20-30 g,were used in the study.The mice of either type were divided into 2 groups (n =6 each) using a random number table:sham operation group (group S) and group I/R.In group I/R,renal I/R was induced by occlusion of the right renal artery for 1 h with atraumatic microclips followed by 2 weeks of reperfusion.The right renal artery was only isolated in group S.At 2 weeks of reperfusion,blood samples were taken from the orbital vein for determination of the concentrations of serum blood urea nitrogen (BUN) and creatinine (Cr).The renal tissues were obtained,and the renal fibrosis area was measured by Sirius Red staining.The expression of fibronectin (FN),collagen Ⅰ (COL-Ⅰ) and α-smooth muscle actin (α-SMA) in renal tissues was detected by immunofluorescence.The expression of signal transducer and activator of transcription 6 (STAT6) and phospho-STAT6 in renal tissues was determined by Western blot.The ratio of phoshop-STAT6 to STAT6 was calculated to reflect the phosphorylation of STAT6.Results Compared with group S of wild type mice,the serum BUN and Cr concentrations and renal fibrosis area were significantly increased,the expression of FN,COL-Ⅰ and α-SMA in renal tissues was significantly up-regulated,and the phosphorylation of STAT6 in renal tissues was significantly increased in group I/R of wild type and IL-4Rα KO mice (P<0.05).Compared with group I/R of wild type mice,the serum BUN and Cr concentrations and renal fibrosis area were significantly decreased,the expression of FN,COL-Ⅰ and α-SMA in renal tissues was significantly down-regulated,and the phosphorylation of STAT6 in renal tissues was significantly decreased in group I/R of IL-4RαKO mice (P<0.05).Conclusion The mechanism of renal fibrosis following renal I/R injury is partially related to IL-4R,and IL-4R results in renal fibrosis through promoting activation of STAT6 signaling pathway in mice.
