Objective To evaluate the efficacy and safety of postoperative analgesia in continuous Interscalene brachial plexus block by different strength ropivacaine mesylate combined with sufentanil.Methods Ninety cases of upper limb surgery in continuous peripheral nerve block (CPNB) were selected.The patients after the operation were divided randomly into three groups (A,B,and C):A group was treated with 0.158％ ropivacaine mesylate + 0.5 μg/ml sufentanil,B group with 0.238％ ropivacaine mesylate + 0.5 μg/ml sufentanil,and C group with 0.238％ ropivacaine mesylate.20 minutes before the end of surgery,controlled analgesia device was connected with infusion rate 0.05 ml/(kg · h),PCA 1 ml,and lock time 15 min.The pain visual analog score (VAS),Ramesay sedation score,and postoperative motor nerve block recovery ratings (modified Bromage classification) were recorded at the 4,8,16,32,48 h time point postoperatively.The times of using PCA and the frequency of the adverse reaction were also recorded.Results Three groups all got good analgesic effect at 4,8,16,32,48 h time point postoperatively (VAS 1.58 ± 9 ; 1.90 ± 0.8 ; 1.62 ± 0.6 ; 1.59 ± 0.7 ; 1.53 ± 0.7) (P ＞ 0.05) ; There were no significant difference among the three groups in Ramesay score,modified Bromage score,limb discomfort,nausea,vomiting,lethargy,pruritus and respiratory depression (P ＞ 0.05),but the time of using PCA in A group were significantly more than that in B or C group (P ＜ 0.05).Conclusions Sufentanil can enhance the analgesic effect significantly when the ropivacaine mesylate is in low concentrations (0.158％ ～0.238％),but when the ropivacaine mesylate concentration get up 0.238％,there will be similar analgesic efficacy and safety between ropivacaine mesylate only and ropivacaine mesylate combined with sufentanil.

Objective To evaluate the value of (1 ,3)‐β‐D‐glucan(G test) in the diagnosis of invasive pulmonary fungal infection (IPFI)in patients with chronic obstructive pulmonary disease (COPD) .Methods 96 COPD patients with high risk of IPFI were en‐rolled in the study ,and were divided into IPFI group and non‐IPFI group .The G test were performed on those people while the tra‐ditional methods sputum smear and fungal culture were also performed .The (1 ,3)‐β‐D‐glucan concentrations of IPFI group and non‐IPFI group were compared ,and then the areas under receiver operating characteristic curve (ROC) were calculated .The sensi‐tivity ,specificity ,positive predictive value ,negative predictive value ,and the area under ROC of the two methods (G test and tradi‐tional methods) were compared .Results The sensitivity ,specificity ,positive predictive value ,negative predictive value of G test were 89 .5% ,89 .6% ,68 .0% ,97 .2% ,respectively ,when 20 pg/mL was the critical value .Areas under curve were 0 .942 for G test ,and 0 .790 for traditional method .Conclusion The detection of (1 ,3)‐β‐D‐glucan might be faster and with higher positive rate than traditional method ,and could be used for the early diagnosis of IPFI ,provide reference for the treatment .

Objective To study the relationship between cognitive dysfunction and depression and event-related potential(ERP) in patients with silent brain infarction(SBI).Methods 68 SBI patients were tested by the Hamilton Depression Rating Scale for Depression(HAMD),scale of mini mental state examination(MMSE)and ERP;and the results were compared with those in 55 patients without cerebral infarction(control group).Results In the SBI group,the HAMD score was ≥17 in 31(45.6%)cases(depression subgroup)and

OBJECTIVE:To observe the effect of cefoperazone on the surgical haemostastic outcome so as to offer reference for preoperative anti-infection medication.METHODS:A total of 60 patients undergoing laparotomy were randomly divided into medication group(cefoperazone)or control group.The blood coagulation functional parameter changes of the 2 groups before and after operation were observed,and the intraoperative blood loss volume,blood infusion volume,and the haemostatic time were recorded.RESULTS:The thrombin time,the prothrombin time,partial prothrombin time were all longer,and the intraoperative blood loss volume and blood infusion volume and the haemostatic time were all more in cefoperazone-treated group than in control group(P

Objective To study the interactive debridement methods in treatment and nursing of the wound in patients with abdominal surgical incision infection.Methods In May 2010 to December 2013 in West China hospital of Sichuan University,54 patients with postoperative incision infection accompanied with tissue necrosis after gastrointestinal surgery were divided into two groups,23 cases who accepted interactive debridement treatment were set as the observation group,31 cases with traditional dressing hypertonic saline gauze debridement were named as the control group.The wound debridement completion time,wound healing velocity,wound healing time,dressing change frequency and cost were compared between two groups of patients.Results Compared with those of the control group,in the observation group,the wound debridement completion time was shorter,wound healing velocity was faster,dressing change frequency was longer.Although single dressing change cost was higher in the observation group,but the total dressing change cost was lower compared with the control group.Conclusions The interactive debridement methods used in treatment and nursing of patients with abdominal surgical incision infection showed good effect and safety,which is worthy of wide clinical application.

Objective To analyze the clinical and pathological features of limb-girdle muscular dystrophy2B(LGMD2B).Methods The clinical and pathological features of 7 patients with LGMD2B were analyzed retrospectively.Results Seven patients had a slow onset,and progressive proximal muscle weakness,muscle atrophy,progressive,and incresed serum creatine phosphokinase; muscle biopsy showed different degree of muscle fiber degeneration,necrosis; stromal and inflammatory cell infiltration in muscle fiber; monoclonal antibody immunohistoehemical staining:showed expression of Dysferlin protein was not found in muscle cell membrane,Dystrophin,Sarcoglycans protein expression was normal.Monoclonal antibody immunohistochemical staining the proteins were expressed in normal cell membrane.Conclusions LGMD2B is a slow onset,progressive proximal muscle weakness,muscle atrophy.Histochemical staining on the basis of further immunohistochemical staining,to detect the membrane protein and Dysferlin protein expression,that is a necessary means to diagnose LGMD2B and inflammatory myopathies.

OBJECTIVE To discuss the reasonable application of multi-enzyme abluent in the process of endoscopic cleaning and disinfecting.METHODS The multi-enzyme abluent was reasonably used to clean the endoscope in the pre-cleaning and disinfection process at thebedside,to enable it to achieve the best cleaning effect.RESULTS The reasonable application of multi-enzyme abluent could enhance the effect of endoscope cleaning to ensure the success of endoscopic disinfection.CONCLUSIONS Multi-enzyme abluent can protect the successful endoscopic disinfection and prevent the iatrogenic infection.

Objective To analyze the prevalence season and trend of meningococcal disease in China by epidemic years from 2004 to 2008 in order to provide scientific basis for making strategies of meningococcal disease prevention and control.Methods The incidence numbers of meningococcal disease were calculated by weeks,epidemic years and areas.The seasonality and prevalence trends of meningococcal disease were analyzed by circular distribution.Results The incidence trend of meningococcal disease had obvious seasonality in China (P
