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 investigate the effect of different doses of dexmedetomidine(Dex)on sevoflurane consumption in patients undergoing laparoscopic oophorocystectomy.Methods Eighty ASA Ⅰ or Ⅱ patients aged 25-50 yr with body mass index 18-25 kg/m2 undergoing laparoscopic oophorocystectomy were randomly divided into 4 groups (n =20): control group (group C),low dose Dex group(group DL),medium dose Dex group(group DM) and high dose Dex group(group DH).Normal saline 20 ml and Dex 0.3,0.6,0.9μg/kg was infused iv over 10 min at 10 min before skin incision in groups C,DL,DM and DH,respectively.End-tidal sevoflurane concentration (ETsev) was recorded before Dex administration(T1 ),skin incision(T2 ),immediately after pneumoperitoneum (T3 ),10 min of pneumoperitoneum(T4 ) and the end of surgery (T5 ).Duration of anesthesia,consumption of sevoflurane,emergence time,extubation time were recorded and restlessness at 10 min after extubation was also recorded.The concentrations of blood glucose and corticosteroid were measured by quickly by glucose analyzer and radio-immunity gefore anethesia induction (T0) and at T3,T4,T5 respectively.Results The consumption of sevoflurane per hour,ETsev at T2-5,concentrations of blood glucose and corticosteroid at T3-5 were decreased gradually in groups C,DL,DM and DH ( P ＜ 0.05).The emergence time and extubation time were shorter and the incidence of restlessness was lower in groups DL,DM and DH than in group C ( P ＜ 0.05 ).Conclusion Dexmedetomidine can reduce the consumption of sevoflurane in a dose-dependent manner in patients undergoing laparoscopic oophorocystectomy.

Objective To compare magnetic resonance spectroscopy (MRS) characteristics and changes before and after 5-Fu interventional thermochemotherapy (ITC) as well as to analyze the correlation of Cho/Lip and apoptosis index (AI) in hepatic VX2 carcinoma animal model.Methods 20 rabbit models of hepatic VX2 carcinoma were implanted successfully.Ten days later,as tumor diameter≥ 10 mm,routine scan and 1H-MRS were performed before one day and after 14 days on all of rabbits by Philips 1.5T MR scanner.The changes of Cho peak,Lip peak and the ratio of Cho/Lip before and after the treatment were analyzed.Specimens of AI were examined and compared with the ratio of Cho/Lip.Results The Cho peak and Lip peak were increased before ITC.After ITC,the Cho peak and the ratio of Cho/Lip decreased than before.The Lip peak was further increased than that of before.AI was correlated negatively with the ratio of Cho/Lip (r =-0.56,P =0.02).Conclusions The metabolites of different ROI are matched with the levels and scopes of AI.1H-MRS can be used to evaluate tumor cell apoptosis and energy metabolism changes of the rabbit models of hepatic VX2 carcinoma with the treatment.
