ObjectiveTo observe the difference in analgesia effects of ropivacaine with fentanyl used intraarticularly after the single knee arthroscopy procedure.Methods40 patients performed knee arthroscopy under combined spinal-epidural anaesthesia( CSEA),were randomly divided into 4 groups (n =10),at the end of operation 10mlof different drug at the group F,R,FR and N(fentanyl 10μg,0.5％ ropivacaine,fentanyl 10μg +0.5％ ropivacaine,normal saline)were injected intra-articularly.The antalgic effects of four groups based on standard of VAS were observed at the 2,4,8,12 and 24h after operation.ResultsThe 2h postoperative VAS scores were lower in four groups,the differences in four groups were not significant.The 4,8,12,24h postoperative VAS scores of F,R and FR group were much lower than that of N group ( all P ＜ 0.05 ).Moreover,VAS scores of FR group were much lower than that of F and R group( all P ＜ 0.05 ).No other adverse effects were observed.ConclusionIntra-articular administration of ropivacaine with fentanyl could provide superior postoperative analgesia without side effects.It was an excellent regimen for analgesia after knee arthroscopy.

Objective To analyze the serum level of 25-hydroxy vitamin D [25-(OH) D] in pregnant women in Nanjing and its relationship with age,gestational week,pre-pregnancy body mass index (BMI) and season,so as to provide some guidance on clinical application of vitamin D measurement and supplementation.Methods 880 pregnant women (in 21-36 gestational weeks) regularly visiting antenatal clinic in Obstetrics and Gynecology Hospital Affiliated to Nanjing Medical University were selected from January to December 2015.Their serum 25-(OH)D concentrations were measured by enzyme-linked immunosorbent assay (ELISA).Results The mean serum 25-(OH) D concentration in these pregnant women was (42.03 ± 19.22) nmol/L and sufficient in only 42 (4.77％).Vitamin D levels showed seasonal variation (P =0.0164),with the levels in summer [(44.61 ±23.57) nmol/L] and autumn [(43.43 ± 19.31) nmol/L] being higher than spring [(39.68 ± 16.91) nmol/L] and winter [(39.65 ± 13.36) nmol/L].There was no statistically significant difference in serum vitamin D level among different gestational weeks (P =0.929 4).There was statistically significant difference in serum vitamin D level among different age groups (P =0.038 3).Vitamin D level was not associated with pre-pregnancy BMI.Conclusions Vitamin D deficiency is highly prevalent among pregnant women in Nanjing.We suggest vitamin D testing be carried out more actively.

Objective To master the actual work efficiency situation of emergency inspection,analyze the existing problems,and provide objective basis for continuous improvement through the statistic analysis of intra-laboratory turn-around time (TAT) median,coincidence rate of inspection report within the specified time limit,report timeout reasons and other indexes of different items of emergency inspection group in 2015.Methods All kinds of original data from the different items of emergency inspection groupswere derived from LIS system,according to the different types of projects in different segments.Microsoft Excel2003 software was used to count the actual TAT time of various items,and function was used to calculate TAT median;The non-conformance rate (inspection report timeout rate) and coincidence rate within the prescribed time limit by inspection report were calculated,and gather the statistical analysis on the timeout reasons of daily recorded report.Results With the exception of electrochemical luminescence class,the TAT of other items decreased in different degrees of emergency inspection group in 2015 when compared with 2014.The average coincidence rate of inspection report of various items within the time limit was 94.8%,non-conformance rate of inspection report of prescribed time limit was 5.2%.The top four inspection timeout reasons of various items were more number of submitted samples(59.6%),redo the reinspection (12.4%),smear reinspection (12.0%) and equipment failure (10.0%) in turn.Conclusion The time limit of the emergency report meets the specified requirements and statistical analysis of the causes of overtime can find out the problems and take appropriate measures to provide an objective basis for continuous improvement.

Objective To explore the immunomodulatory effects of 1,25-dihydroxyvitamin D3 (1,25 (OH)2D3) in the treatment of experimental colitis induced by dextran sulfate sodium (DSS) in mice.Methods According to random number table,thirty BALB/c mice were randomly divided into control group,model group,low dose,moderate dose,and high dose intervention group.Mice of model group,low dose,moderate dose and high dose intervention group drank 5％ DSS solution for seven days to create colitis model.On the 1st,3rd,5th,7th day,the mice of low dose,moderate dose and high dose intervention group were intraperitoneal injected with low,moderate,and high dose of 1,25(OH)2D3 (50,100 and 200 ng/each mouse,respectively).Mice of control group and model group were intraperitoneal injected with sterile soybean oil as control.The observed indicators included disease activity index (DAI) and colonic histopathological score (HPS).On the 8th day,all mice were sacrificed.The expression of interferon (IFN)-γ,interleukin (IL-17) and IL-21 in mice colon tissues and spleens at mRNA and protein level were measured by reverse transcription-polymerose chain reaction (RT-PCR) and flow cytometry,respectively.The data were analyzed by one way ANOVA.LSD-test or Tamhane test were performed for comparison in groups.Results Compared with the control group,the DAI and colitis HPS of mice in the model group significantly increased (0.33±0.52 vs 7.33±1.03,0.17±0.41 vs 12.00±0.63).Compared with the model group,the DAI and colonic HPS of intervention groups treated with 1,25 (OH)2 D3 declined with varying degrees (2.83 ± 0.40,2.83±0.75,2.33±0.52 and 10.83±0.98,7.50±0.84,6.67±0.52,LSD-t=0.39 and 0.41,all P＜0.01).The expression of IFN-γ,IL-17 and IL-21 of the model group were significantly higher than those of the control group.The expressions of IFN-γ,IL-17 and IL-21 of intervention group were signifiantly lower than that of the model group (mRNA:LSD-t =0.12,0.13,0.09; protein:F =20.61,22.46,4.80,all P＜0.01).Conclusion 1,25 (OH)2D3 might have a direct role on T-cell phenotype,down-regulate effective cytokines IFN-γ,IL-17 and IL-21 and then play an interventional role.

Objective To study the effectiveness and safety of different endoscopic papillary balloon dilation time in treatment of common bile duct stones. Methods 45 patients with common bile duct stones received ERCP treat﹣ment, and they were randomly divided into short-term and long-term balloon dilatation group, then compared opera﹣tive time, intraoperative and postoperative complication rate, hospitalization days and the total cost of hospitalization between the two groups. Results Short-term group included 22 people, the long term group included 23 people, there were no significant difference in stones' size, number and diameter of common bile duct between the two groups (P> 0.05), however, the success rate of surgery, time of stones' extraction, intraoperative complications and postoperative fistula were significant differences (P<0.05). Conclusion Long-term balloon dilation during ERCP for treatment of common bile duct stones can improve the success rate of stone removal and reduce complications.

Background:The incidence of inflammatory bowel disease(IBD)is increasing recently. However,the pathogenesis has not been fully clarified. Aims:To investigate the expressions and significance of interleukin-22( IL-22),matrix metalloproteinase-9(MMP-9)and macrophage migration inhibitory factor(MIF)in peripheral blood of patients with IBD. Methods:A total of 80 patients with IBD admitted from May 2011 to Nov. 2014 at the First Affiliated Hospital of Soochow University were enrolled,in which 43 cases were Crohn’s disease(CD),37 cases were ulcerative colitis(UC). Forty healthy subjects were served as normal controls. Peripheral levels of IL-22,MMP-9 and MIF were detected by ELISA. Multivariate Logistic regression model was used to analyze IL-22,MMP-9 and MIF in active CD and UC and ROC curve was used to evaluate the diagnostic performance of these markers for screening of active CD and UC. Results:Compared with normal control group,peripheral levels of IL-22,MMP-9 and MIF increased significantly in CD and UC groups(P <0. 05),while no significant difference was found between CD and UC groups(P > 0. 05). Peripheral levels of IL-22, MMP-9 and MIF in active CD and UC were significantly higher than those in remission stage(P < 0. 05). For screening of active IBD,the area under ROC curve(AUC)of combined detection of IL-22 and MMP-9(0. 853 for CD,0. 867 for UC) was superior to that of IL-22,MMP-9 or MIF only(0. 747,0. 770 and 0. 699 for CD,0. 774,0. 815 and 0. 761 for UC). Conclusions:Peripheral levels of IL-22,MMP-9 and MIF increase markedly in IBD patients,which are correlated closely with the activity of IBD. Combined detection of IL-22 and MMP-9 might greatly increase the accuracy for screening of active IBD.
