A group adopted patient controlled epidura analgesia(PCEA) micro-injection pump;B group using patient controlled intravenous analgesia(PCIA) mi-cro-injection pump,patients were observed and recorded for their pain, vomit disgustingly, exsufflation and the time of first urination or accidentally tube pull-out. Results The time of average surgery for A, B group were (53.5±8.5) min, (54.7±8.2) min, between the two groups was not significant (t=1.524, P>0.05) ; A group of visual Analog score (1.49±0.43) points were significantly higher than B group (1.13±0.56) points(t=2.119,P<0.05) ;the incidence of headache, dizziness, nausea and vomiting, skin itching(30.0%, 16.0% ,6.0%) in A group were signifi-candy higher than B group(16.0%,8.0% ,2.0%) (t=2.223, t=2.313, t=2.283, all P>0.05) ; the time of A first exhaust,voiding time[(24.56±8.77) h, (6.51±1.57) h] in A group were significantly higher than B group [(19.29±8.16)h,(4.06±1.76)h](t=2.445,t=2.415,P<0.05). Conclusion PCIA method was safe,effec-tive and allowed patients to have early activities after treatment and to promote early rehabilitation. It should be promo-ted for cesarean section.

Objective To investigate the streptomycin(SM)-resistance of Mycobacterium tuberculosis (MTB) in urine and to examine their relationships with the mutation of rspL gene. Methods 47 strains of MTB were isolated from the urine of patients with renal tuberculosis.The mutation of rspL gene were analyzed by PCR-SSCP with silver-staining,and the strains were tested for the sensitivity to streptomycin. Results All the 47 strains had positive expression of rspL gene of MTB,with 28 SM-resistant and 19 SM-sensitive.Among the 28 SM-resistence strains 19(68%) had rspL gene mutation by SSCP testing.The 19 strains of SM-sensitive had no mutation. Conclusions Detecting mutation of MTB rspL gene in urine by PCR-SSCP can rapidly and exactly identify the MTB's sensitivity to streptomycin,which is significantly important in clinical treatment of anti-tuberculosis.

Objective To evaluate the effectiveness of epidural saline washout on regression of sensory and motor block after epidural anesthesia in elderly patients.Methods A total of 70 males with ASA Ⅰ or Ⅱ who were subjected lumbar epidural anesthesia with 10 ml of 1.73% bicarbonate-lidocaine and fentanyl 50 μg (1 ml).At the end of transurethral surgery,the washout group (35 cases) received an epidural bolus of 20 ml saline while the control group(35 cases) did not,extracted the epidural catheter after 10 minutes.Results Mean times of 3-dermatomal sensory regression for pinpric, 1-grade of motor block, and the rate of 1 h motor block were significantly shorter in the washout group than those in the control group [(24.6 ± 15.9) min vs(32.8 ± 16.7) min, (32.7 ± 13.4) min vs(47.9 ± 22.6) min,5 cases (14.3%) vs 14 cases (40.0%)](P < 0.05 or < 0.01 ).There was no difference in pain-killer utilization, postoperative pain scores no more than 3 scores and side effects between the two groups (P > 0.05).Conclusion It suggests that epidural washout facihtates regression of both sensory and motor block following epidural anesthesia without reducing the postoperative analgesic benefit.

Objective To investigate the MRI features of pilomyxoid astrocytoma ( PMA ) in children.Methods MRI features of seven children with pathologically proven PMA in 2011-2013 were retrospectively analyzed.The ages of the patients ranged from 10 months to 32 months at initial diagnosis.Results All tumors were well-circumscribed masses.Six tumors were located in the hypothalamic-chiasmatic-third ventricular region , two tumor involved the bilateral temporal lobe , and one tumor was associated with NF-I.One occurred in the basal ganglia region.Four tumors were solid masses , whereas the other three showed cystic components.Six tumors were hypointense and one was isointense on T 1-weighted image.Five tumors were hyperintense and three were isointense on T 2-weighted image.Four tumors were hypointense , one was iso-hypointense and one was isointense on DWI.After contrast administration , four tumors enhanced homogenously and three tumors enhanced heterogeneously , with intratumoral irregular hypointense region in two tumors and rim enhancement in one tumor.Cerebrospinal fluid ( CSF ) dissemination, hydrocephalus and peritumor edema were observed in 2, 4 and 1 of cases, respectively.Proton magnetic resonance spectrum of two PMA showed elevated Cho /Cr ratios and decreased NAA/Cr ratios.Conclusions The imaging features of pilomyxoid astrocytoma include common origination from the midline of the neuroaxis in younger children about 2-3 years old.The CSF dissemination is common.The presence of hemorrhage and peritumor edema is not common.

Objective To investigate the association of red cell distribution width (RDW) with outcome in patients with septic shock.Methods A retrospectively study was performed on a total of 156 cases with septic shock who hospitalized in the Affiliated Hospital of North China University of Science and Technology from January 2012 to December 2014.All cases were divided into two groups according to the outcome:survivor group and non-survivor group.The data of general information,combined disease,RDW,acute physiology and chronic health score(APACHE Ⅱ) were collected and compared between the two groups.All cases were divided into three subgroup in regard of RDW,group A was ≤ 14.0％,group B was 14.1％-15.9％,group C was ＞16.0％.Multiple Logistic regression analysis was performed to analyze the related factor of mortality.ROC analysis was used to test the predictive effect of RDW for the outcome of septic shock.Results Sixty-nine cases died in 156,with a mortality rate of 44.2％(69/156).The RDW in non-survivor group was significantly higher than that of survivor group((15.79±2.64) ％ vs.(12.69±3.09) ％,P＜0.001).Mortality rate in each sub-group were 21.5％ (14/65) in group A,49.0％ (25/51) in group B,75.0％ (30/40) in group C,respectively,and the difference among the three groups was statistically significant (x2 =29.396,P ＜ 0.001).Logistic regression analysis showed RDW was independently associated with mortality of septic shock.In reference with group A,the risk of mortality was 3.504 (95％ CI:1.563-7.858,P =0.002) in group B and 10.924 (95％ CI:4.314 -27.661,P＜0.001) in group C.Conclusion Red cell distribution width is a risk factor of mortality in patients with septic shock.

Objective To explore the expressions of stromal cell derived factor 1 α (SDF-1α) and cysteine-X-cysteine chemokine receptor 4 (CXCR4) in the peripheral blood of patients with systemic lupus erythematosus (SLE).Methods Forty hospitalized SLE patients were recruited and twenty healthy volunteers were enrolled as normal controls.The percentage of CD3+CD4+CXCR4+,CD3+CD8+CXCR4+ and the plasma concentration level of SDF-1α in the control group and SLE patients were detected by flow cytometry and ELISA.The relationship between SDF-1α/CXCR4 and SLEDAI was explored.Kruskal-Wallis H,Pearson's and Mann-Whitney U test were used for statistical analysis.Results the expression of SDF-1α [329 (127,539) pg/ml] and CXCR4 [CD3+CD4+CXCR4+:4.20(2.01,6.35)％,CD3+CD4+CXCR4+:2.70(1.68,4.20)％] were significantly elevated in SLE patients when compared to the normal controls (Z=-6.277,-5.707,-4.885,respectively,all P=0.000),and were significantly increased in highly active SLE patients than less active SLE (Z=-5.414,-5.256,-5.312,P＜0.01).The expression of SDF-1α and CXCR4 in the butterfly erythema group,anemia group and proteinuria group were significantly higher than the normal group (P＜0.05).Both SDF-1αand CXCR4 were positively correlated with SLEDAI (r=0.857,0.830,0.861,respectively,all P＜0.01).Conclusion The expressions of SDF-1α and CXCR4 increase significantly in the peripheral blood of SLE patients and there is close relationship between SDF-1α/CXCR4 and disease activity,organ damage.The results of this study suggestthat SDF-1α/CXCR4 may play an important role in the pathogenesis of SLE.

The concentrations of borneol in the serum and brain tissue of rats were determined by gas chromatography. Using brain tissue as a relatively independent system, PHARMFIT and PCNONLIN softwares are applied for the kinetic analysis of the infracorporal process of borneol in order to find out and compare the pharmacokinetic characteristics of borneol in the brain and serum. The results showed that borneol was absorbed very rapidly in the gastrointestinal tract and readily permeates the blood-brain barrier into brain tissue. There was a higher specific value of borneol concentration in the brain and serum. Moreover, the half life of distribution phase of borneol in the brain was three times higher than that in the serum. But the constants of elimination rate of borneol in the brain and serum decreased simultaneously and parallelly, hence the accumulation of borneol in brain will not be found.
