Objective To observe the recovery efficiency of sufentanil and oxycodone hydrochloride in neurosurgical operation.Methods Total of 120 patients scheduled for microvascular decompression under general anesthesia were randomly divided into 4 groups to receive 0.03 mg·kg-1 oxycodone (group H1), 0.05 mg·kg-1 oxycodone (group H2), 0.08 mg·kg-1 oxycodone (group H3), and 0.08 μg·kg-1 sufentanil (group S).Each patient accepted 4 ng·mL-1 of remifentanil and 5-6 mg·kg-1·h-1 of propofol after induction to maintain bispectral index (BIS) value at 40-60.On starting to suture dura mater, oxycodone or sufentanil was given in various doses through intravenous route.The BIS value, the amount consumption of propofol, anesthesia and operation duration, and the drug delivery time of each group were recorded.The time of spontaneous breath recovery, awaking and extubation, verbal rating score (VRS) and sedation score (SS) at 10 min, 20 min, 30 min after operation as well as side-effects were also recorded.Results The VRS scores had no statistic difference among the groups at 10 min after operation, while the average scores of H1 were higher than those of H2 and H3 at 20, 30 min after operation.No statistic difference of the SS scores was showed among 4 groups at 10 min after operation, but it was lower in group H1 than those in group H3, and lower in group S than those in H2 at 20 min after operation;group H3 had a significantly higher SS scores than H1, H2 and S at 30 min after operation.Conclusion Oycodone hydrochloride 0.05 mg·kg-1 or sufentanil 0.08 μg·kg-1 can both provide satisfactory recovery quality in neurosurgical operation.

Objective To observe the clinical effects and intubation condition of different doses of domestic cisatricurium(CA) in children. Methods Forty-five peadiatric patients aged 2 to 12 years old scheduled for selective surgery were randomized to three groups of 2 ED_(95) CA(0. 08 mg/kg), 3ED_(95) CA(0. 12 mg/kg) and 4ED_(95) CA(0. 16 mg/kg) (C_2, C_3, C_4 groups). Neuromuscular blockade was monitored with TOF-Guard. The conditions for trachea[intuDation were scored and the onset time, clinical duration, recovery index were recored. ResultsTracheal intubation was performed successfully in all patients. The conditions for tracheal intubation were scored greater 5 points in groups of C_3 and C_4 ,which was only 33. 3% of patients in group C_2. The onset time was shortened and the duration of action was prolonged as the dose of CA increased. But the recovery index of three groups were smilar. Conclusion An increase of CA dosage can shorten the onset time and prolong the duration of action and 3ED_(95) CA is suitable for tracheal intubation in children.

Objective To investigate the effect of thiopental on lipopolysaccharide(LPS)-induced activation of nuclear factor kappa B(NF-κB) under different concentration or after different time in rat glioma cells in vitro.Methods The rat C 6 glioma cells were treated with,in the presence or Absence of various concentrations(10-3 mol/L,10-4 mol/L and 10-5 mol/L)of thiopental for 1 h.30 min before harvest,the cells were exposed to LPS(10 ng/ml).The other C 6 cells were treated with 10-5 mol/L thiopental with different time(0.5 h,1 h,2 h,4 h).30 min before harvest,the cells were exposed to LPS(10 ng/ml).Nuclear extracts from C 6 cells were harvested using standard procedures,and the LPS-induced NF-κB expression was determined with electrophoretic mobility shift assays(EMSA) and measured with densitometry(Bio-Rad).Results The width of the bands of NF-κB under thiopental with different concentrations were similar,but they were narrower than that of the control(treated only with LPS),the density was less than that of the control(P<0.05).The width of the bands of NF-κB under thiopental with different time decreased with the time(P<0.05),and they were much narrower and shallower than that of the control(P<0.05),and the density was significantly less than that of the control(P<0.05).Conclusion Thiopental suppressed the activation of transcription factor NF-κB,and the inhibition was concentration-independent but time-dependent.

The rate of blinding caused by high myopic maculopathy is high, vitrectomy is the most common treatment. However, the effectiveness of vitrectomy for high myopic patients who have serious posterior scleral staphyloma is not ideal. Recent years, posterior scleral reinforcement is used as a supplementary method with vitrectomy in clinical, treating for high myopic maculopathy. lt achieves a positive curative effect especially in macular foveoschisis and macular hole cases. ln this article, we introduced a review of history, current situation, material and surgery operand of scleral reinforcement. lt also makes a further discussion of its prospects used in retina surgery.

Objective To investigate the potential role of FoxP3-expressing CD4+CD25+ regulatory T cells in children with asthma.Met-hods Intracellular 3-colour flow cytometry and real time PCR were used to assess the expression of FoxP3 in peripheral blood mononuclear cell(PBMC)of asthma,repectively.Results There were similar frequencies of CD4+ CD25+ T cells in peripheral blood of asthma patients and healthy subjects.However,the percentage of CD4+CD25high and CD4+CD25+FoxP3+ in asthma group were lower than those in healthy subjects(Pa

Objective To assess the effects of different doses of oxycodone hydrochloride on spontaneous breathing and consciousness level of patients,so as to provide theoretical basis for its clinical application.Sixty patients undergoing elective surgery were randomly divided into 3 groups:0.05 mg · kg-1 oxycodone group (group P1),0.1 mg· kg-1 oxycodone group (group P2),0.2 mg· kg-1 oxycodone group (group P3).Changes of respiratory rate (RR),end tidal carbon dioxide partial pressure (PETCO2),saturation of blood oxygen (SpO2) and bispectral index (BIS) were recorded in patients before injection (t0) and 1-15 min after injection (once per min);the Observer's Assessment of Alertness/Sedation Scale (OAA/S) were recorded.At the same time,the adverse reactions were observed after drug injection in each group.Results In 10 min after injection there were no significant differences in the RR,SpO2,PETCO2,BIS and OAA/S in group P1 as compared with those before injection (P＞0.05).The patients had no respiratory depression in group P1.In group P2,RR had a significant decrease (P＜0.05),BIS had decreased but were greater than 85;there were no significant differences in the SpO2,PETCO2 and OAA/S (P＞0.05).The P2 group had 3 cases with respiratory frequency＜10 per min,but SpO2 were all greater than 94％.In group P3,There were significant differences in the RR,SpO2,PETCO2,BIS and OAA/S (P＜0.05).The P3 group had 12 cases of respiratory frequency ＜10 per min,at the same time there were 8 patients with SpO2 less than 94％.With the increasing dose,the frequency of respiratory inhibition increased,and there were statistical differences (P＜ 0.05).In 15 min after injection,RR,SpO2,PETCO2,BIS and OAA/S were not significantly different in group P1 and P2 as compared with those before injection (P＞0.05).In group P3,RR was significantly different after injection (P＜0.05).There were no significant differences in the SpO2,PETCO2,BIS and OAA/S in group P3 after injection (P＞0.05).No patients complained with chest wall stiffness,nausea and vomiting,cough and other adverse reactions in group P 1 and P2.In group P3,three patients had nausea 5 min after injection,two patients complained of chest skin itching but no skin flushing.Conclusion With the increasing dose,effect of oxycodone hydrochloride on breathing and consciousness level of patients gradually increased.Injection of oxycodone hydrochloride 0.05 mg · kg-1 had no obvious effect on breathing and consciousness.After injection of oxycodone hydrochloride 0.1 and 0.2 mg · kg-1 for 5 to 10 min,respiration inhibition and sedative effect were the most obvious.Fifteen min after injection,the 0.1 mg · kg-1 dose group recovered to the level before,the respiratory rate of the 0.2 mg · kg-1 dose group was still lower than that before the injection.

Objective:To observe the curative effect of cervical chiropractic for cervical spondylosis of vertebral artery type (CSA) and to explore its possible mechanism.Methods:Sixty CSA patients were randomly divided into two groups.Thirty patients in the treatment group were treated with chiropractic manipulation for cervical vertebrae,once every other day,7 treatments in total.The other 30 patients in the control group received oral administration of flunarizine hydrochloride,10 mg per night,for 14 d.Cervical vertigo and functional assessment scale and transcranial cerebral Doppler (TCD) were measured before treatment and 7 days after treatment.Results:The total effective rate was 96.7％ in the treatment group and 83.3％ in the control group.The curative rate was 66.7％ in the treatment group and 20％ in the control group.The differences between the two groups in the total effective rate and the curative rate were statistically significant (both P＜0.05).The scores of cervical vertigo symptom and functional assessment after treatment in both groups were significantly higher than those before treatment (both P＜0.01);the difference between the two groups was statistically significant (P＜0.05).After treatment,the maximum systolic velocity (Vs),the maximum diastolic velocity (Vd),the mean velocity (Vm),the pulsatility index (PI) and the vascular resistance index (RI) in both groups were significantly improved compared with those before the treatment (all P＜0.01);there were significant differences between the two groups (all P＜0.05).Conclusion:Cervical chiropractic is an effective method for CSA,and its curative effect is better than that of flunarizine hydrochloride alone.Its mechanism may relate to correcting cervical instability.

Objective To study the protective effect of garlicin on radiation injury in mice. Methods Sixty mice were randomly divided into five groups:model control group, solvent control group and garlicin treatment groups[0.17, 0.33, 1.00 g/(kg?d)]. After treated by gavage for 20 consecutive days, the mice were exposed to 60Co-? irradiation for one time and the effect of the irradiation on the amounts of WBC in peripheral blood, the ratio of micronucleus cells in marrow, the content of DNA in marrow cells and the superoxide dismutase (SOD) activity were measured. Results Compared with the exposure group, garlicin increased the amounts of WBC, decreased the micronucleus frequency of marrow cells, increased the content of DNA in marrow cells and increased the SOD activity in mice. Conclusion Garlicin shows a protective effect on irradiation injury in mice.

Objective To study the effects of overdose fluoride on blood lipid and hemorheology in rabbits and the protective effect of selenium. Methods Twenty male rabbits were divided into 4 groups: normal group,fluorine group(100 mg/L),selenium group(1 mg/L) and selenium (1 mg/L) plus fluorine (100 mg/L) group. After 6 months of treatment,whole blood rheology,blood serum TC,TG,HDL-C,LDL-C,SOD activity,GSH-Px activity,the content of MDA were determined. Results The whole blood rheology of rabbit in fluorine group was abnormal. Compared with the normal group,significant increase of blood serum TC,HDL-C,LDL-C was seen,decrease of SOD activity and GSH-Px activity and increase of the content of MDA in fluorine group was found. The results of selenium plus fluorine group was more close to the normal group compared with fluorine group. Conclusion Fluorosis can induce hemorheology and lipid metabolism disorder and decrease the capacity of antioxidase and moderate selenium intake may have some protective effect.
