Objective To evaluate the clinical value of ulinastatin on the treatment of systemic inflammatory response syndrome in severe acute panereatitis. Method Eighty-four patients with severe a-cute pancreatitis were randomly divided into two groups. In the treatment group (42 cases),on the base of routine treatment, ulinastatin was administered intravenously for seven days after hospitalization, while in the control group only routine treatment was given (42 cases) to. Inflammatory factors in serum, the change of liver function and renal function were measured in two groups before and after the treatment, and the clinical efficacy were observed. Results There was significant difference, in the serum level of tumor necrosis factor-α, interleukin-1, interleukin-6, alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen and creatinine on the 7th day between two groups (P < 0.05 or < 0.01 ) ,there were significant differences in the incidence of complications, hospitalization time, incidence of multi-organ failure between two groups [14.3%(6/42) vs 38.1%(16/42), (29.4 ± 1.5)d vs (34.4 ± 1.8)d, 28.6%(12/42) vs 47.6%(20/42), P<0.01 or <0.05 ]. Conclusions Ulinastatin can suppress the secretion and release of some inflammatory factors, protect the important viscera functions and reduce the incidence of complications, and it has favorable clinical efficacy.

Objective:To evaluate the uncertainty in carbamazepine ( CBZ) determination in human plasma by HPLC-MS/MS. Methods:The whole process of CBZ determination was analyzed and the uncertainty sources were established, and then the uncertainty was evaluated and combined, and the expanded uncertainty was also calculated. Results: The expanded uncertainty of CBZ with low (7.46 ng·ml-1) and high (745 ng·ml-1) levels was 0.410 ng·ml-1 and 33.400 ng·ml-1, respectively (P=95%, k=2). Conclusion:The uncertainty in CBZ determination in human plasma by HPLC-MS/MS is mainly caused by recovery, sample prepara-tion and matrix effect for low concentration, and by sample preparation and repeatability for high concentration.

Objective To study the skills of facial nerve preservation in acoustic neuroma microsurgery. Methods Seventy four cases of acoustic neuromas treated microsurgically by suboccipital retrosigmoid transmeatus approach were analyzed retrospectively, including their clinical symptoms and characteristic image, the pathological anatomic relationships of facial nerve and tumor, microsurgical technique. Results Total resection of the tumor was achieved microsurgically in 72 cases, subtotal resection in 2 cases. Facial nerve was kept anatomic intact in 67(90.5%) of the patients. Intracranial end to end anastomosis of the facial nerve was performed in 4 cases. No patient died in this series. Conclusions Microneurosurgical technique is a safe and effective method for total resection of acoustic neuroma. It is key point for keeping facial nerve anatomic intact to understand the pathological anatomic relationships of facial nerve and tumor.

OBJECTIVE:To establish and validate the method for the determination of carbamazepine (CBZ) in human plas-ma,and to apply the method for external quality assessment. METHODS:After precipitated with acetonitrile,the plasma sample was determined by LC-MS/MS. Using loratadine as internal standard,the determination was performed on Kromasil C18 column with mobile phase consisted of water (containing 0.1% formic acid)-acetonitrile (gradient elution) at flow rate of 0.6 ml/min and column temperature of 40 ℃. The ion transitions under MRM mode by ESI+ ionization were performed at m/z 237.1→194.0 and m/z 383.1→267.0 for CBZ and internal standard,respectively. RESULTS:The linear range of CBZ were 5-1 000 ng/ml (r>0.998). The limit of quantitation was 5 ng/ml. RSDs of inter-day and intra-day were 1.00%-6.42%;relative deviation were -6.93%-0.32%. The external quality assessment of 5 samples were 679.0,475.0,104.0,29.2 and 26.2 ng/ml,respectively. The pass rate of assess-ment result was 100%. CONCLUSIONS:The method is sensitive,accurate and specific. The method is applicable for the plasma concentration determination and external quality assessment of CBZ.

Objective To analyze the clinical features of hepatic veno-occlusive disease (HVOD) and to explore the diagnosis criteria and treatment.Methods A total of 50 cases of HVOD administrated at The First Affiliated Hospital of College of Medicine,Zhejiang University from August 2008 to August 2011 were analyzed for etiology,clinical manifestation,laboratory examination,image,pathological features and treatment.Results Among the 50 HVOD cases,38 cases (76%)had a history of taking Gynura segetum.The main clinical manifestations were ascites,hepatomegaly,right upper quadrant pain,jaundice,and weight gain.Laboratory examinations indicated liver function injury and increased serum CA125 level.Color Doppler ultrasound showed hepatomegaly,decrease in diameter of hepatic vein and slow blood flow.The computed tomography scan suggested hepatomegaly,enhanced scan showed liver inhomogeneous enhancement at portal and delayed phase,map-like changes and markedly decrease in diameter of hepatic vein.Pathological examination suggested hepatic sinusoid congestion,central vein stenosis and vessel wall thickening.The main therapy was anticoagulant treatment.One case cured,33 cases improved,13 cases uncured and three cases died.Conclusions HVOD because of taking Gynura segetum is common in Zhejiang Province,which can be diagnosed according to medical history,clinical manifestations, and typical image characteristic.However,diagnosis of the atypical cases still needs liver biopsy.Anticoagulation therapy can achieve better efficacy.

Objective To report the results of balloon catheter dilation in 13 infants with anastomotic stenosis after surgical correction of esophageal atresia. Methods Thirteen cases of anastomotic stenosis after surgical correction of esophageal atresia were enrolled, age ranging from 3 to 10 years. Barium esophagography before balloon dilation showed the diameter of esophageal stenosis ranging 1 to 3 mm and the stenosis was dilated by using balloons of 6 to 12 mm diameter. Results All the 13 cases obtained complete resolution of the stenosis after dilation for twice or thrice. There was no esophageal perforation or other complications with a period of clinical symptomless of 6 to 30 months. Conclusions Ballon catheter dilation is a simple, safe and reliable method for treating anastomotic esophageal stenosis in infants.

Objective To evaluate the role of interventional therapy in Wilm's tumor, renal vascular lesions and ureter stricture in children. Methods Thirty-eight cases were analysed, including 18 cases of Wilm's tumor treated with preprocedural chemotherapy and embolization through renal artery, and 13 cases of unknown-reason hypertension with selective renal arterial angiography for venous blood renin including undergone some patients PTA. Six cases of ureter stricture were dilated with balloon and 1 with hematurea by small aerial embolization. Results After embolization, Wilm's tumors showed reduction in vascularization and reduction in size too. The surrounding tissue of the tumor had a clear demarcation with the normal tissue, decreasing the dissemination to blood and distal metastasis. Renal vascular hypertension was clearly diagnosed and treated, and the increase of renin was helpful to the diagnosis of unknown-reason hypertension. And the obstruction of ureter was improved. Conclusions Interventional therapy is feasible in the application of urinary system diseases with great significance clinically.
