The fermentation conditions of alkaline lipase producing by Pseudomonas cepacia PCL-3 were optimized.Based on the analysis of single factorial experiments,dextrin was the most suitable carbon source,peptone and urea were the suitable compound nitrogen sources among the examined materials.Three significant factors(urea,inoculum and initial pH) were selected from the eight factors related to lipase production by Plaekett-Burman method,and were further optimized with response surface analysis.And then,steepest ascent procedures were applied to define the optimal response region of the three factors.The obtained optimal conditions were urea 0.15%,inoculum 3.05% and initial pH 8.38,under which conditions,the enzyme activity was improved from 25.37 U/ml to 48.88 U/ml,enhanced 1.93 folds.Starting from the flask conditions,the highest lipase activity of 47.69U/ml was achieved by batch fermentation in a 10 L fermentor after 52 h of the cultivation.

Objective:Three-dimensional (3D) ultrasound (US) is increasingly being introduced in the clinic,both for diagnostics and image guidance.Although dedicated 3D US probes exist,because of its expensive cost,3D US can also be acquired with the still frequently used two-dimensional (2D) US probes.Methods:Obtaining 3D volumes with 2D US probes is a two-step process.First,a positioning sensor must be attached to the probe for 2D image matching;second,a reconstruction of a 3D volume can be performed into a regular voxel grid.Results:This paper presents a way to realize the 3D US in irled-based Image Guided Radiotherapy using a homemade 2D US.Conclusions:The experiments demonstrate a method of saving costs and having advantages in clinic application.

Objective To evaluate the efficacy of radiosynovectomy with 32P colloid in haemophilic synovitis of adolescents. MethodsRadiosynovectomy with 32P colloid was primary performed on 26 male haemophilic patients(26 joints),whose average age was 16 years(11 to 21 years).The average dose of 32P colloid was 2.1 mCi(1.0 to 3.0 mCi). Results After 6-month interval,haemarthrosis was reduced by no less than 30% in 23 patients,with a total efficacy of 88.5%.The mean frequency of haemarthrosis was reduced from 1.9 per month of presynovectomy to 0.3 per month of postsynovectomy(P

Objective To investigate the prevalence and risk factors of atherosclerotic renal artery stenosis (ARAS) in patients with ischemic stroke (IS).Methods A total of 596 consecutive patients with ischemic stroke underwent cerebrovascular and renal angiography at our hospital from January 2008 to March 2013.Renal artery stenosis was defined as at least one of renal artery narrowing ≥ 50% of luminal diameter.Multivariate logistic regression analysis was performed to investigate the association of the clinical variables with ARAS.Results Intracranial arterial stenosis (ICAS) was identified in 203 patients (34.1%),including 108 cases (18.5%) with arteriostenosis ≥ 50%.Extracranial arterial stenosis (ECAS) was identified in 250 patients (41.9%),including 149 cases (25.0%) with arteriostenosis ≥ 50%.The prevalence of ECAS was higher than that of ICAS(x2 =7.86,P < 0.05).ARAS was identified in 77 patients (12.9%),and the prevalence of ARAS in patients with ECAS ≥50% was higher than that in with ICAS ≥50% (30.2 % vs.18.5%,x2 =4.52,P <0.05).Multivariate analysis showed that the age≥ 60 y (OR:2.48,P < 0.05) and ECAS ≥ 50% (OR:5.37,P < 0.05) were independent risk factors for prevalence of ARAS.Conclusion ARAS is a relatively common finding among patients with ischemic stroke,suggesting that renal angiography should be performed in elderly IS patients,especially for those combined with severe ECAS.

Objective To investigate the feasibility and safety of primary closure of common bile duct following laparoscopic common bile duct reexploration and choledocholithotomy for recurrent or residual choledocholithiasis in patients with prior biliary surgery.Methods We retrospectively studied the clinical data of 31 patients who were diagnosed recurrent or residual common bile duct (CBD) stones after prior bile duct surgery.All of 31 patients had undergone primary closure following laparoscopic common bile duct reexploration between Jan 2010 and Jan 2014.Results In all the 31 patients,there was no conversion to open surgery.There were no complications due to port placement,postoperative bleeding and mortality.The operation time was (106 ±32) min; the volume of intraoperative blood loss was (52 ± 16) ml; the time of postoperative gastrointestinal function recovery and postoperative hospital stay were (23 ± 3) h,(5.5 ± 1.5) d respectively.Duodenal injury was found and repaired intraoperatively laparoscopically in one patient.Bile leakage occurred in 2 cases recovered by conservative therapy.No postoperative stricture of bile duct,recurrent or residual stones were observed during a period of 1 month to 1 year (mean follow-up 6 months).Conclusions Primary closure following laparoscopic common bile duct reexploration for patients with a past history of biliary tract operation is safe,feasible,and effective procedure in hands of experienced laparoscopic surgeons.

Objective To explore the effects of lifestyle intervention on index of early artery diseases in nondiabetic patients with metabolic syndrome (MS). Methods Eighty-seven nondiabetic patients with MS were randomly assigned to the intervention group ( n =47) and the control group ( n =40).The patients in the intervention group received health education,diet control,regular physical exercises,and unhealthy habit correction; however,the control group did not receive any intervention.All the patients were followed up for 9 months.Body mass index (BMI),waist circumference (WC),systolic blood pressure (SBP),diastolic blood pressure (DBP),triglyceride (TG),total cholesterol (TC),high-density lipoprotein cholesterol ( HDL-C ),low-density lipoprotein cholesterol ( LDL-C ),fasting blood glucose (FBG),HbAlc,fasting insulin (FINS),HOMA-IR,high sensitivity C-reactive protein (hs-CRP),carotid intima-media thickness (IMT),brachial-ankle pulse wave velocity (baPWV) and ankle-brachial index(ABI) were measured at baseline and at 9 months.ResultsAfter 6 or 9 months' intervention,BMI,WC,SBP,TG,HDL-C,FPG,HbAlc,FINS,HOMA-IR and hs-CRP of the intervention group were improved (all P < 0.05). HDL-C,FPG,HbAlc,FINS,HOMA-IR and hs-CRP of the intervention group were further improved at 9 months when compared to 6 months ( all P < 0.05 ). In comparison with the control group,BMI,WC,HDL-C,FPG,HbA1 c,FINS,HOMA-IR and hs-CRP were significantly improved in the intervention group at 9 months ( all P < 0.05 ).After 6 or 9 months' intervention,baPWV and ABI were significantly changed ( both P < 0.05 ) in the intervention group although IMT of the carotid did not changed (P >0.05). BaPWV and ABI were significantly changed in the intervention group when compared with those in the control group at 9 months ( both P < 0.05).The abnormal rate of baPWV in the intervention group at 9 months was 44.68%. BaPWV and ABI were associated with hs-CRP and HOMA-IR.ConclusionsIn nondiabetic MS patients, health management could significantly improve insulin resistance,modify metabolic disorders,and prevent the development of atherosclerosis.
