40 cases of parotidectomy were reviewed.Anterograde approach(group A)and retrograde approach(group B)for facial nerve dissection were used in 1 7 and 23 cases respectively.1 patients in group A and 8 in group B presented symptoms of temporary facial nerve paralysis(P <0.05).The anterograde method is safer and quicker.

Objective To analyze causes for postoperative fixation-related complications of femoral in- tertrochanteric fractures treated with dynamic hip screws(DHS)and dynamic condylar screws(DCS).Methods From January 1995 to December 2004,215 cases of intertrochanteric fracture were treated with DHS/DCS.Their postoperative fixation-related complications were analyzed to find out the causes.Results All cases were followed up for 13 to 72 months(mean,32 months).The rate of excellent and good functional recovery of hip was 94.0%. Postoperative internal-fixation-related complications occurred in 31 cases,including hip varus in 14 cases who had posterior intertrochanteric fragments,delayed union of fracture in 12 cases who had fractured calcar and lesser trochanter and massive dissection of soft tissues,and cutting-out of lag screws in five cases,three of whom had to receive prosthetic replacement.Conclusions Unsuitable implant selection is an important factor leading to postoperative fixation-related complications.Unstable fracture,serious osteoporosis and unsatisfactory reduction will increase the incidence of complications.

Objective To explore the optimal power of experimental pancreatic endoscopic ultrasonography (EUS)-guided radiofrequency ablation (RFA) therapy.Methods Six healthy live minipigs were randomly divided into two groups according to random number table,which received RFA under EUS or in laparotomy.Each pig in each group was randomly allocated to received RFA at different power (5 W,10 W,15 W).The impedance was monitored and the time for each therapy was recorded.The width diameter of coagulation necrosis from RFA was measured by EUS and gross pathology.Results RFA was completed in all pigs smoothly with stable life signs and without complications.Gross and micro pathologic observation confirmed formation of coagulation necrosis lesions.The width diameter of lesions from EUS-RFA was similar to that from surgery RFA,both having a maximum value at 10 W power (11 nun VS 10 mm).Conclusion The optimal power of experimental pancreatic EUS-RFA in pig is 10W,which should be further explored for the clinical purpose.

Based on the strain breeding theory and metabolic engineering theory, A high-yield mutant of Lactobacillus Thermophilus ATCC8317 was obtained through the compound inducements by the original Acetic acid-Sodium acetate plate and the productivity increased 210%.The best media components included saccharifying corn,malt powder 30g/L,peptone 5g/L.Based on the variety of specific cell growth rate and specific L-lactic acid production rate at different temperatures, the strategy of temperature control was obtained. The total product of L-lactic acid reached 135g/L besides the rate of glucose consumed and the average L-lactic acid productivity were up to 95% and 2.25g/(L?h) respectively.

97 cases of jaw bone fractures were treated with rigid internal fixation.16 cases had malocclusion postoperation.The etiology was analyzed and the prevention methods were proposed.Intermaxillary elastic traction or fixation and craniomaxillofacial fixation or craniomentum elastic traction were performed to treat the malocclusion.By this way,14 cases were cured.1 case was operated again to resume the normal occlusion,1 case received occlusal adjustment.Incomplete reduction,incorrect operative performance,deficiency of postoperative intermaxillary fixation and incorrect intermaxillary fixation were the main causes to malocclusion.So anatomic in time reduction,correct operative performance,intermaxillary fixation,application of craniomaxillofacial fixation or craniomentum elastic traction instead of intermaxillary fixation for some special cases are effective methods to correct postoperative malocclusion.

Objective To evaluate skin barrier function in children with atopic dermatitis (AD) as well as healthy children from two communities in Shanghai and to assess the relationship between skin barrier function and AD severity.Methods Totally,169 children with AD and 142 healthy children aged 3-12 years were recruited from two communities (Changning Xining community and Jiading Juyuan community) in Shanghai,China.Transepidermal water loss (TEWL) and stratum corneum hydration were measured in normal appearing nonlesional skin at four body sites (dorsal and volar forearm,cheek and anterior shin) of the patients,as well as in normal skin at the same sites of the controls.AD severity was evaluated by using the severity scoring of atopic dermatitis (SCORAD) index.Results Compared with the healthy children,the patients with AD showed higher TEWL value at all of the four body sites (all P ＜ 0.05),but lower water content in stratum corneum at dorsal forearm and anterior shin (both P ＜ 0.05).In patients with AD,the SCORAD index was positively correlated with mean TEWL value,but negatively correlated with the mean water content in stratum corneum.Conclusion Skin barrier function may serve as an index for evaluating the severity of AD.

Objective To evaluate angiography and interventional embolization in diagnosis and treatment of massive hemobilia.Methods During 10 years,9 patients with massive hemobilia underwent emergency selective hepatic artery angiography to find the bleeding points,and then embolized the feeding branches.Results All cases demonstrated clearly on angiography about the arterial hemorrhage,and extravasation of contrast-medium.Hemorrhage was stanched immediately after embolization of the feeding branches of the hepatic artery.Conclusion Selective hepatic angiography and interventional embolization for massive hemobilia is a safe and efficient diagnostic and therapeutic method.(J Intervent Radiol,2006,15:213-214)

Objective: To study the effect of Shenxiong Xintong Pill(SXP) on cardiac hemodynamics. Methods: Parameters of cardiac hemodynamics were examined in anesthetic chest-opened dogs medicated with various doses of SXP. Results: After intraduodenal administration of SXP of 2.0g/kg, the coronary blood flow was raised, coronary resistance decreased, heart rate slowed and the left ventricular diastolic end pressure fallen in the dogs. No obvious changes were found in the contraction , works and ejection of left ventricle. Conclusion: The mechanism of SXP in relieving angina pectoris was probably related to the dilatation of coronary artery and increase of coronary flow with the increase supply of oxygen.

Objective To evaluate the efficacy and safety and to analyze related complications and potential prognostic factors of allogeneic hematopoietic stem cell transplantation(allo-HSCT ) on hematological malignancies .Methods Patients with hemato-logical malignancies who underwent allo-HSCT from June 2010 to June 2015 were investigated in this retrospective study .Accord-ing to the donor types ,it was divided into compatriots sibling-matched transplantation group (n = 52) and haploid transplantation group (n= 98) .The preconditioning regimens were busulfan/cyclophosphamide ,and anti-thymocyte globulin were needed in haploid transplantation group .Short-term methotrexate + cyclosporine A + mycophenolate mofetil were used for prevention of graft-ver-sus-host disease .The efficacy and safety and related complications of allo-HSCT were analyzed .Results All patients achieved full donor type engraftment ,which was identified by blood type ,chromosome test and DNA polymorphism .The mean times of neutro-phil and platelet engraftment were 12 d and 16 d in compatriots sibling-matched transplantation group and 13 d and 16 d in haploid transplantation group ,respectively .59 cases (39 .3% ) patients were oral mucosa ulcer ,47 patients (31 .3% ) were bacteria and/or fungal infection ,41 cases (27 .3% ) patients were CMV infection ,48 cases (32 .0% ) were acute GVHD ,43 patients (28 .7% ) were chronic GVHD .The median follow-up time of 23 months (1 - 60 months) ,115 patients (76 .7% ,115/150) were disease-free sur-vival ,including 38 cases (73 .1% ,38/52) in compatriots sibling-matched transplantation group ,77 cases (78 .6% ,77/98) in haploid transplantation group ;35 cases (23 .3% ,35/150) patients were died ,including 14 cases (26 .9% ,14/52) in compatriots sibling-matched transplantation group ,21 cases (21 .4% ,21/98) in haploid transplantation group .Death cause analysis showed that 12 ca-ses (8 .0% ) complications from transplantation related death ,of which 5 cases (3 .3% ) were severe infection ,7 cases (4 .7% ) caused by acute GVHD ,23 cases (8 .7% ) patients died because of the primary disease recurrence .The survival rate and mortality was similar between the two groups (P> 0 .05) .Conclusion Allo-HSCT is safe and effective treatment in hematological malignan-cies .The curative effect and security with haploid transplantation were similar to compatriots sibling-matched transplantation .It is necessary to prevent prognostic impact factors such as acute GVHD and infection early .
