Objective To discuss the etiology and treatment of extrahepatic biliary stenosis due to iatrogenic bile duct injuries. Methods A total of 12 cases of extrahepatic biliary stenosis after iatrogenic bile duct injuries(including 5 cases of open cholecystectomy and 7 cases of laparoscopic cholecystectomy) from January 1998 to January 2005 in this hospital was reviewed.After the establishment of a percutaneous transhepatic access,choledochoscopic stone removal,balloon dilatation,and drainage stent placement were performed for treating biliary stenosis.Results A F_(20) Gruntzig balloon catheter was employed for bile duct dilatation.The plastic drainage stent at 6~8 mm in diameter was successfully placed after 2 times of dilatation in 8 cases and after 3 times of dilatation in 4 cases,for 6~12 months of indwelling.Follow-up observations in the 12 cases for 2~3 years (mean,2.6 years) found no abdominal pain,fever,or jaundice.B-ultrasonography and MRCP findings showed no biliary stenosis and recurrent stones.Conclusions Choledochoscopic stone removal,balloon dilatation,and drainage stent placement are minimally invasive,safe,and effective in the treatment of extrahepatic biliary stenosis.

Objective To investigate methods and effects of percutaneous choledochoscopy via cholangio-jejunal anastomotic stoma in the treatment of recurrent intrahepatic biliary duct stones. Methods Eight cases of recurrent intrahepatic biliary duct stones after a Roux-en-Y cholangiojejunostomy from January 2000 to February 2005 were treated with percutaneous choledochoscopy. An enterostomy was made at the afferent jejunal loop. Then a choledochoscope was introduced into the intrahepatic biliary ducts by way of the cholangio-jejunal anastomotic stoma for stone removal and intrahepatic duct or anastomotic stoma dilatation. Results The intrahepatic stones were thoroughly removed in all the 8 cases. The biliary duct stenosis in 4 cases and the anastomotic stoma stenosis in 2 cases were relieved. Follow-up checkups in the 8 cases for 1~3 years revealed no recurrence of intrahepatic stones or stenosis. Conclusions Percutaneous choledochoscopy via cholangio-jejunal anastomotic stoma is minimally-invasive, safe, feasible, and effective in the treatment of recurrent intrahepatic biliary duct stones.

ObjectiveTo explore the therapeutic effect of continuous veno-venous hemofiltration (CVVH) on the treatment of severe acute pancreatitis (SAP).MethodsAll data about forty-five patients with SAP admitted to the intensive care unit (ICU) from June 2005 through June 2010 were reviewed.These 45 patients were randomly (random number ) divided into routine treatment group (n =22 )and comprehensive treatment group ( n =23 ).In control group,patients were rapidly given with a suffficient liquid support,vasoactive drug to increase organ perfusion,trypsin secretion inhibitor,broad-spectrum antibiotics,enteral nutrition with intestine membrane protective agent in early stage.In the comprehensive treatment group,patients received CVVH integrated with routine treatment.On admission and 72 h posttreatment,the scores of acute physiology and chronic health evaluation Ⅱ ( APACHE Ⅱ ) and multiple organ dysfunction syndrome (MODS),and the results of standard bettery of biochemistry tests indcluding blood urea nitrogen (BUN),serum cratinine (Scr),total bilirubin (TBIL),alanine aminotransferase (ALT),amylase (AMS),C-reactive protein (CRP),TNF-α,IL-6,IL-8 were observed.Time of mechanical ventilation support,length of ICU stay,and survival rate were compared between two groups.ResultsOn admission between the two groups,no statistical significance was seen in the APACHE Ⅱ and MODS score,BUN,Scr,TBIL,ALT,AMS,CRP,TNF-α,IL-6,IL-8 (P ＞ 0.05).But APACHE Ⅱ and MODS score were decreased significantly in comprehensive treatment group than in the routine treatment group,as well as the the level of BUN,Scr,TBIL,ALT,AMS,TNF-α,IL-6,IL-8 and CRP after 72h post-treatment (P＜0.05 ).In routine treatment group and comprehensive treatment group,the time of respirator intervention and length of stay in ICU were (7.6±3.4) d vs.(11.5±4.7) d,(12.3±7.8) dvs.(17.6±9.2) d respectively,the statistical significance was shown ( P ＜ 0.05 ).Compared to the comprehensive treatment group ( 86.96％ ),the survival rate ( 59.09％ ) were lower in routine treatment group ( P ＜ 0.05 ).ConclusionsCVVH combined with routine treatment,which can remove inflammatory agents and toxins,maintain homoeostasis,and improve oxygenation,is effective in treatment of SAP and can improve patient survival rate.

Objective To compare the effect of 4 different cold and hot properties of traditional Chinese medicine (TCM) on body temperature and related factors of yeast induced fever rats,and discuss the thermoregulatory mechanism of cold and hot properties of TCM.Methods 108 male SD rats were randomly divided into a normal group,a yeast-induced group,a R.palmatum treated group,a C.chinensis treated group,a Euodia ruticarpa treated group,and a Alpinia officinarum Hance treated group,with 18 rats in each group.Pyrexia model was induced by injecting yeast suspension subcutaneously on rat.At the 4h,8h and 12h after injection of yeast,the rats were sacrificed,and the blood and hypothalamus were collected.The levels of prostaglandin E2 (PGE2),cyclic adenosine 3',5'-monophosphate (cAMP) and arginine vasopressin (AVP) in hypothalamus and plasma were detected by ELISA assay.Results At the 4h after injection of yeast,the temperature of rats in the model group began to rise,and it reached the peak at 8h,while RheumpalmatumL and Coptis chinensis could significantly reduce the body temperature of yeast-induced rat (P＜ 0.01 or P＜ 0.05).At 8h,the levels of PGE2 and cAMP in hypothalamus increased significantly [respectively (31.55 ± 9.88) pg/mg and (0.17±0.03) pmol/mg] compared with the normal group,while the level of AVP (0.14±0.02) pmol/ml in plasma reduced (P＜0.05).Compared with model group,at 8h RheumpalmatumL and Coptis chinensis could significantly lowered PGE2 [respectively (113.65± 18.60) pg/mg and (127.72 ± 15.75) pg/mg,P＜ 0.01 or P＜0.05],and cAMP [respectively (0.69±0.08) pmol/mg and (0.74±0.10) pmol/mg,P＜0.05] in hypothalamus,and increased AVP levels [respectively (1.08 ± 0.12) pmol/ml and (0.91 ±0.01) pmol/ml,P＜0.05 or P＜0.01] in plasma.Euodia ruticarpa and Alpinia officinarum had no significant effect on both body temperature and the levels of inflammatory factors.Conclusion The two cold property traditional Chinese medicines,R.palmatum and C.chinensis,could significantly reduced the body temperature of yeast-induced rats,which may be related to its effective regulation on levels of PGE2 and cAMP in hypothalamus and AVP in plasma,however,the two hot property traditional Chinese medicine,Euodia ruticarpa and Alpinia officinarum Hance,had no related effects.

Objective To investigate the clinical features and effective treatment of patients with severe type A H1N1 flu in Wenzhou. Methods The clinical data of 42 hospitalized patients with severe type A H1N1 flu were analyzed and the clinical features were summarized. Results A total of 42 patients with severe type A H1N1 flu all began with fever and cough. The symptoms of expectoration, pharyngalgia, chilly accounted for 92. 9%, 90. 5% and 42. 9%, respectively. The peripheral leucocyte counts were normal or reduced. C-reactive protein and erythrocyte sedimentation rate levels both increased in 30 patients (71.4%). About 95.2% (40/42) patients had changes of pulmonary imaging. All of the patients were treated with oseltamivir and effective antibiotic drugs as well as symptomatic management. No patients was treated with glucocorticoid. The patients with underlying diseases were given proper treatment. Three cases were treated with antifungal therapy and 3 pregnant patients were timely terminated of pregnancy. Conclusions Severe type A H1N1 flu progresses rapidly and the lower respiratory tract is involved soon after onset. Therefore, the patient should be diagnosed early and treated promptly after presenting fever, which will lead to good prognosis.

Objective To explore the effect of entire process nursing intervention during nebulization treatment of acute wheezing episodes in school-age children.Methods One hundred and forty-one children with acute wheezing episodes were divided into the experimental group (75 patients) and the control group (66 patients) by whether willing to accept nursing intervention or not,respectively.Routine nursing such as cognition of wheezing knowledge and respiration instruction was given to both groups,while specialists accompanied the whole procedure of inhalation treatment and they gave nursing intervention such as respiration,saliva swallow,expiration through nose,grasp of inhalation tank and body position maintenance to the experimental group.The improvement of wheezing and subjective sense by the patients,transcutaneous oxygen saturation (SaO_2),and the compliance of patients were measured and evaluated.Results Improvement of wheezing and comfort feeling were found in 97.3% of the experimental group,while 80.3% of the control group.And SaO_2 value (higher than 95%) was 92.0% in the experimental group,75.8% in the control group.The compliance of the experimental group was also better than the control group.Conclusions Entire process nursing intervention during nebulization treatment can improve clinical effect and the compliance of wheezing children.

Objective To observe the morphology of ethanol-wet dentin surfaces and detect their nano-scale adhesion force (Fad) by atomic force microscopy (AFM) in order to explore the potential mechanism of ethanol-wet bonding in improving clinical dentin bonding effectiveness.Methods Dentin slices from human premolar roots were prepared into flat ones, polished, and then randomly divided into five groups.All the specimens were acid-etched, rinsed, and left moist.They were then treated with 100％ ethanol for 0s (control group), 20s, 60s, 3×60s, or stepwise ethanol application.Afterwards, each group was scanned for the morphology in air and the Fad was probed by AFM.One-way ANOVA followed by Tukey`s test was employed for multiple comparisons using SPSS16.0.Results Compared with control group, ethanol-wet dentine produced a less undulating and relatively smooth surface topography.Ethanol-wet protocol significantly decreased the value of Fad in the experimental groups (P<0.001), in which 3×60s and stepwise ethanol application groups showed the lowest Fad.No difference was found between these two groups (P>0.05).Conclusion When using AFM in air, ethanol-wet protocol with longer time can produce a less undulating and relatively smooth surface topography and decrease the Fad, whichindicates that the water saturated in dentin matrix was replaced more thoroughly by longer ethanol application time.This will benefit hydrophobicity of the dentin bonding interface.

Objective To evaluate the surgical technique and the clinical effect of applying free superficial palmar branch of the radial artery flap to repair soft tissue defect of finger pulp.Methods From June,2011 to December,2013,12 cases of soft tissue defect of finger pulp and bone exposed were treated with free superficial palmar branch of the radial artery flap.The flap was designed from the proximal end of palmar wrist and the donor site was sutured directly.The size of the harvested flaps was between 2.5 cm × 1.0 cm and 6.2 cm × 3.8 cm,and the sensation of the flap was reconstructed via median nerve cutaneous branch.Results All transfering flaps survived and all cases were followed up for 4 to 17 months.The donor site got primary healing with a straight car.The appearance and texture of the flaps were satisfactory.2-point discrimination ranged from 6 to 11 mm.The pain sensation,warmth sensation and touch sensation of the flap got better.Conclusion The free superficial palmar branch of the radial artery flap is easy to harvest and anastomose,which is masked and a small incision for the donor site.The appearance and sensation of the flap which has sensory nerve branched for sensory reconstruction is satisfactory.It is an ideal method for the repairment of finger pulp defects.
