Objective To investigate the clinical effect of ulinastatin in preventing pancreatitis after endoscopic retrograde cholangiopancre-atography (ERCP).Methods The Cochrane Library,PubMed,EMBASE,CNKI,VIP,and Wanfang Data were searched for randomized controlled trials (RCTs)on ulinastatin for the prevention of post -ERCP pancreatitis published from 1970 to June 2016.Two researchers se-lected RCTs,extracted data,and evaluated methodological quality independently,and RevMan 5.3 software was used for the meta -analy-sis.The chi -square test was used for the heterogeneity analysis of RCTs included,and the funnel plots were used to evaluate publication bi-as.Results A total of six RCTs with 923 patients were included in this analysis.Compared with the placebo,ulinastatin had significantly better effects in preventing post -ERCP pancreatitis (OR =0.26,95%CI:0.13 -0.53,P =0.000 2),hyperamylasemia (OR =0.47, 95%CI:0.33 -0.67,P <0.001),and abdominal pain (OR =0.56,95%CI:0.34 -0.91,P =0.020).Compared with gabexate,uli-nastatin had similar effects in preventing post -ERCP pancreatitis,hyperamylasemia,and abdominal pain (P =0.52,0.13,and 0.79);low -dose ulinastatin also had similar effects as gabexate in preventing post -ERCP pancreatitis and hyperamylasemia (P =0.49 and 0.25).The funnel plots based on the effect of ulinastatin in preventing post -ERCP pancreatitis were slightly asymmetric,which suggested the presence of publication bias.Conclusion Ulinastatin (≥15 ×104 U)can effectively prevent post -ERCP pancreatitis,hyperlipi-demia,and abdominal pain in the general population and it is recommended to start using this drug before surgery.

Objective To investigate the properties of the abilities of spontaneous counterfactual thinking(SCFT) and induced counterfactual thinking(ICFT) produced by undergraduate students with depressive symptoms.Methods Undergraduates were induced to produce SCFT after recalling a negative event and ICFT after reading a story about a traffic event.Then the undergraduates were demanded to complete the counterfactual inference test(CIT).The amount and rationality of CFT and the scores of CIT were analyzed.Results Mild depressive students(MDS) generated a higher amount of SCFT than non-depressive students(NDS),midrange depressive students and severe depressive students(SVDS)(P0.05).The rationality of SCFT generated by four groups were significantly different(P

OBJECTIVETo study the ischemic times of the main artery injury in the limbs and the influence on the limbs survival rate, and to analyze the reasons for the formation of the ischemia time.

METHODSFrom June 1996 to November 2012, 83 patients with completely severed limb main artery treated in our hospital were retrospectively studied. There were 77 males and 6 females, including 81 adults (ranging in age from 16 to 52 years old, with a median age of 35 years old) and 2 children (4 and 5 years old respectively). Seventy-five patients were treated with end to end anastomosis, 7 patients were treated with great saphenous vein transplantation, and 1 patient was treated with artificial blood vessel transplantation. The prior to admission ischemia time, after admission ischemia time and total ischemia time for successful and unsuccessful patients, as well as the causes of the formation of the ischemia time were studied. Limb survival rate of different ischemic time was counted. Sharpness injury or blunt injury ischemia time and amputation rate were researched statistically. All data were analyzed using SPSS statistical software.

RESULTSThere were 72 limbs survived, 11 amputated. The average ischemia time was (7.45±5.94) h for limb-salvage group and (13.73±14.00) h for amputation group. Prior to admission ischemia time between amputation and limb-salvage group had no significant difference. After admission the ischemia time in amputation group was longer than limb-salvage group. The amputation rate for ischemia time 21 to 44 h group was higher than other three groups (≤ 5 h, 6 to 10 h, 11 to 20 h) (P=0.023, 0.038, 0.044). Amputation reasons can be divided into anastomosis failure in the operation, vascular thrombosis 2 to 4 days after operation and late infection.

CONCLUSIONVascular injury limbs can tolerate longer ischemia time and the limb salvage succeed. Only too long ischemia time (> 20 h), limb amputation rate increases significantly. The main cause of long time ischemia is delayed diagnosis in the hospital. Whether limb-salvage success mainly depends on the degree of trauma and the quality of the anastomosis than ischemia time.

Objective To evaluate the results of endovascular intervention for infrapopliteal arterial occlusion in 40 patients. Methods There were 41 affected limbs in these 40 patients receiving 44 times of endovascular intervention for infrapopliteal arterial occlusion during Nov. 2006 and Dec. 2007. The average age was 76±6. The ABI(ankle brachial index)before intervention was 0.39±0.20 in anterior tibial artery and 0.39±0.23 in posterior tibial artery. CLI (critical limb ischemia) was 80.49% (33/41). Results The after intervention ABI increased by 0.43±0.22 (P<0.01) in anterior tibial artery and 0.43±0.25(P<0.01)in posterior tibial artery. 35 patients (36 limbs) were followed-up for (6±3) months. The limbs of Fontaine Ⅰ and Fontaine Ⅱ A were 28 (77.78%), CLI decreased to 19.44% (7/36) (P<0.01). At follow-up the ABI in anterior tibial artery was 0.63±0.22 and 0.56±0.22 in posterior tibial artery. The difference were all significant when compared with that before intervention and after intervention. The perioperative amputation rate was 0. The perioperative mortality rate was 2.5%. The total mortality rate was 15%. The limb salvage rate were 100%. Conclusion The effect of endovascular intervention for infrapopliteal arterial occlusion is satisfactory.

Objective To observe the effect and safety of treating senile abnormal lipid metabolism with LU Zhi-zheng's dampness-removing,turbid-resolving and heart-communicating formula.Methods 60 patients were randomly divided into a treatment,treated with LU's formula,one dosage per day,and a control group,treated with gypenosides,60mg/tablet,three times per day,with 30 patients in each group.Both groups were treated two therapeutic courses,which were 8 weeks.Results Except HDL-C,other indexes including TC,TG,LDL-C in the treatment group were all obviously improved after the treatment [the statistical values were (5.81 ± 1.70) mmol/L,(3.05±2.30) mmol/L,(3.39± 1.11 ) mmol/L respectively,P＜0.01 or 0.05],which were also better than the control group [the statistical values were ( 6.16 ± 1.91 ) mmol/L,( 3.03 ± 1.89 ) mmol/L,(3.81±0.63) mmol/L,P＜0.01 or 0.05].Symptoms improvement such as chest oppression,dizziness,heaviness of head,headache,sticky mouth without thirsty,constipation,nausea and vomiting,and heaviness of limbs in the treatment group were also better than the control group,with mean rank were 23.83、38.10、36.10、34.70、36.77、39.82、33.38、34.17 respectively.No abnormal changes were found in indexes of blood routine,urinary routine,stool routine,ECG,ALT,AST and Cr.Conclusion LU Zhi-zheng's dampness-removing,turbid-resolving and heart-communicating formula improved clinical symptoms and signs of abnormal lipid metabolism patients,its therapeutic effects were better than gypenosides.

Objective To investigate the value of extravascular lung water (EVLW) in predicting the prognosis of sepsis acute lung injury (ALI) / acute respiratory distress syndrome (ARDS).Methods Relevant published articles concerned with EVLW both in Chinese and in English from 1991-2011 were searched,and Meta-analysis was carried out with Stata software. Results Seven articles were selected for Meta-analysis according to the inclusion and exclusion criteria.The results indicated EVLW of dead patients group kept in a high level,while EVLW showed a down-trend in the survival group.The difference in level of EVLW between the two groups became more obvious with the day ( SMDd1＜ SMDd2 ＜ SMDd3 ) ( the 1st day:SMDd1=0.29,95％CI:0.047-0.532; the2nd day:SMDd2=1.64,95％CI:0.14-3.13; the 3rd day:SMDd3 =1.83,95％ CI:0.56-3.10).Conclusions EVLW and its dynamic change in the early stage of sepsis ALI/ARDS could predict the prognosis.This suggested the sustained high level would lead to high mortality.

Objective To investigate the value of plasma soluble triggering receptor expressed on myeloid cells-1 as a diagnosis marker of sepsis.Methods Articles on plasma soluble triggering receptor expressed on myeloid cells-1 as a marker of sepsis which were public published in the PubMed,Ovid,Springer,Wanfang database from 1991-2012 were searched and conducted a meta-analysis by MetaDiSc and Stata.Results Seven articles were selected to the meta-analysis according to the inclusion criteria,of which cut-off values varied signicantly from studies.Due to the data heterogeneity (I2 ＞ 50％,P ＜0.05),random model was used to pool the effect sizes.The overall combined effect sizes:sensitivity =81％ (95％CI:0.76-0.86); specificity =81％ (95％ CI:0.76-0.86); DOR =30.03 (95％ CI:7.89-114.37) ; AUC of SROC =0.905 9; Q*-0.837 6.Deek' s funnel plot showed little publication bias.Conclusions Plasma soluble triggering receptor expressed on myeloid cells-1 may be a useful adjunctive tool for the diagnosis of sepsis.However,further studies are needed in order to identify the best cut-off value in the diagnosis of sepsis.

BACKGROUND:With the development of industry and agriculture, organotin compounds have been widely used in China. Organotin compounds cause a common occupational poisoning. The toxicity of organotin was reported in animal studies; however the reports about human organotin intoxication are very rare. In this study we retrospectively analyzed the clinical manifestations of 15 organotin-poisoned patients who had been treated at our hospital from 2002 through 2007. METHODS:Fifteen patients with organotin poisoning were admitted to Sir Run Run Shaw Hospital Affiliated to Zhejiang University School of Medicine from 2002 to 2007. They were 9 males and 6 females, aged from 25 to 52 years. Clinical manifestations and Glasgow Coma Scales showed that the poisoning was mild in 4 patients, moderate in 6 and severe in 5. The severe patients were given glucocorticoid after hospitalization by intravenous guttae of 500 mg methylprednisolone for the first day, followed by 160 mg methylprednisolone per day for three days, and then 80 mg methylprednisolone per day for another three days. Potassium glutamate and sodium glutamate were intravenously dripped to reduce blood ammonia; intravenous guttae plus oral administration of potassium 9 g/day was used to correct intractable hypokalemia; sodium bicarbonate was used to correct metabolic acidosis, and sedatives were used to control spasm and twitch; mechanical ventilators were used in 4 patients with dyspnea. RESULTS:Most of the patients showed elevated level of blood ammonia, decreased level of blood potassium and metabolic acidosis, but some had demyelination changes shown by CT and MRI. Treatments included correction of metabolic acids, blood potassium and ammonia, and mechanical ventilation when necessary. For patients with injuries of the nervous system, glucocorticoids were given immediately after hospitalization. These patients showed intractable hypokalemia and metabolic acidosis during the treatment. Forteen patients recovered completely without long-term side-effect. One patient in the aphasiac stage restored the linguistic capacity during a 6-month follow-up. CONCLUSIONS:Elevated level of blood ammonia, decresed level of blood potassium, and metabolic acidosis are common in patients with organotin poisoning. Demyelination can be observed in patients with severe poisoning. The abnormalities of the patients are reversible after suitable treatments.

OBJECTIVETo study the influence of actual defect length and gap width of the limbs main artery on the method selection of repairing and reconstruction.

METHODSRetrospective study was carried out for 32 patients with extremity main artery injury from 1996 to 2009, including 30 males and 2 females; 30 adults with an average age of 36 years old ranging from 18 to 51 years, 2 children of 4 and 5 years old respectively. Injured body parts involved axillary artery in 4 cases,brachial artery in 7 cases,radial artery in 2 cases, femoral artery in 4 cases, popliteal artery in 13 cases, posterior tibial artery in 2 cases. Main arterial injury defect gap width of all cases were observed and the reasons were analyzed. All cases were repaired by the method of end to end anastomosis after vessels stretch.

RESULTSThe artery defect width was 3 cm to 7 cm with an average of (4.375 +/- 1.200) cm. Defect width of the upper extremity brachial artery and axillary artery group was (5.73 +/- 0.63) cm,the lower extremity femoral and popliteal artery group (3.80 +/- 0.73) cm, the posterior tibial artery group (3.25 +/- 0.35) cm, the radial artery group (3.00 +/- 0.00) cm. Defect width of upper extremity brachial artery and axillary artery group was larger than that of the other three groups (P < 0.01). End to end anastomosis was performed successfully in all cases. Blood supply recovered well. Because of the severe limb infection 2 patients had amputation in the late. All patients received follow-up. The patients without fracture were followed up to 2 weeks postoperatively, all patients with fractures were followed up to 1 year at least. Limb blood supply was good in all patients during the follow-up.

CONCLUSIONBlood vessel defect gap width is different from the actual vessel defect, but is larger than the actual vessel defect. Misjudgment of the vascular defect length will lead to more vascular transplantation. The vast majority of vascular defect can be directly repaired by the method of end to end anastomosis after the vessel free and stretch.

Objective To analyze the therapeutic outcomes and adverse effects of high-dose intravenous immunoglobulin (hd-IVIg) in the treatment of some severe skin diseases (toxic epidermal necrolysis, drug hypersensitivity syndrome, connective tissue disease, autoimmune bullous disease, acute graft-versus-host disease). Methods Twenty-five cases of severe skin diseases were treated with hd-IVIg (0.4 g/kg/day for a course of 5 days). Results The therapeutic outcomes were different from each other. Of all the cases, 21 improved, especially those of acute onset of toxic epidermal necrolysis and drug hypersensitivity syndrome; 1 adult dermatomyositis and 2 elder bullous pemphigoid were not relieved. A patient with acute graft-versus-host disease died. Three patients presented with minor adverse effects (headache and blood pressure rising). Conclusions hd-IVIg is effective and safe in the treatment of some severe skin diseases. More importantly, it has a substantial effect on shortening disease course and decreasing the dosage of glucocorticoids and immunosuppressants as well as on preventing infections.
