OBJECTIVE: To establish headspace capillary gas chromatography for the content determination of 3 kinds of residual organic solvent (furanidine,methanol and ethanol) in betamethasone sodium phosphate raw material.METHODS: The sample was dissolved in water and n-propanol was used as internal standard.The residual solvent in betamethasone sodium phosphate was separated on HP-INNOWAX (PEG) capillary column with column temperature set at 60 ℃.The injector temperature and FID detector temperature were controlled at 180 ℃ and 250 ℃,respectively.The carried gas was nitrogen at flow rate of 1.0 mL?min-1.The splitting-ratio was 10 ∶ 1.The containers of head-space injector were in equilibrium at 80 ℃ for 30 min.Injection time was 1 min.RESULTS: With this chromatographic condition,those solvents could be separated completely.The linear range were 0.014 4～0.071 8 mg?mL-1 for furanidine,0.060～0.300 mg?mL-1 for methanol and 0.099 3～0.497 mg?mL-1 for ethanol.The average recovery were 103.7% (RSD=0.53%,n=6),95.8% (RSD=0.30%,n=6) and 95.0% (RSD=0.48%,n=6) respectively.The minimum quantitation limit were 0.057 3 ?g?mL-1,0.486 ?g?mL-1,0.145 ?g?mL-1,respectively.3 kinds of residual organic solvents were all in line with the standard stated in Chinese Pharmacopeia.CONCLUSION: The established method is simple,sensitive and accurate for the content determination of residual solvents in betamethasone sodium phosphate raw material.

Objective To investigate the experiences in the diagnosis and treatment of space-occupying lesions of the head of pancreas.Methods The clinical data of 247 patients with space-occupying lesions of the head of pancreas who were admitted to the First Affiliated Hospital of Chinese Medical University from January 2011 to April 2014 were retrospectively analyzed.All the patients received enhanced computed tomnography and (or) magnetic resonance imaging of the pancreas.The levels of alpha-fetal protein (AFP),CA19-9,CA125 and carcinoembryonic antigen (CEA) were detected,and the serum level of IgG4 was detected in patients who were suspected of autoimmune pancreatitis.Intraoperative pathological examination was applied to patients who were diagnosed as with cancer of the head of pancreas.Pancreaticoduodenectomy,extended pancreaticoduodenectomy or bilio-jejunostomy or (and) gastrointestinal anastomosis were applied to patients according to the stage and infiltration of the tumor.Duodenum-preserving pancreatic head resection or pancreaticoduodenectomy could be selected after informed consent.The adjacent tissues and organs should be preserved on the premise of complete tumor resection for patients with benign and low-grade malignancy.Results A total of 194 patients had solid spaceoccupying lesions of the head of pancreas,including 125 with pancreatic head cancer,45 with mnass in the head of pancreas,9 with chronic pancreatitis with mass in the head of pancreas,11 with autoimmune pancreatitis,4 with insulinoma.Fifty-three patients were with cystic space-occupying lesions,including 12 with mucinous cystadenoma,8 with serous cystadenoma,17 with pancreatic cyst,12 with solid-pseudopapillary tumor of pancreas and 4 with intraductal papillary mucinous neoplasm.The positive rates of AFP,CA19-9,CA125 and CEA of the 71 patients who were confirmed as with pancreatic cancer by pathological examination were 7.0％ (5/71),94.4％ (67/71),42.3％ (30/71) and 0,respectively.The positive rates of AFP,CA19-9,CA125 and CEA of the 12 patients with chronic pancreatitis with mass in the head of pancreas were 1/12,4/12,1/12 and 0,respectively.Seventynine patients with pancreatic head cancer,mass in the head of pancreas and chronic pancreatitis with mass in the head of pancreas received intraoperative pathological examination.A total of 119 patients received operation,including 71 with pancreatic head cancer,7 with chronic pancreatitis with mass in the head of pancreas,4 with insulinoma,1 with pancreatic tuberculosis,8 with mucinous cystadenoma,4 with serous cystadenoma,6 with pancreatic pseudocyst,1 with huge lymphangioma,1 with lymphoepithelial cyst,12 with solid-pseudopapillary tumor of pancreas and 4 with intraductal papillary mucinous neoplasm.Of the 247 patients with space-occupying lesions of the head of pancreas,61 received pancreaticoduodenectomy,4 received duodenum-preserving pancreatic head resection,4 received pancreatic head and neck resection,2 received partial resection of the uncinate process of the pancreas,9 received enucleation of the tumor,38 received bilio-jejunostomy or (and) gastrointestinal anastomosis,22 received endoscopic retrograde cholangio-pancreatography + stent installation,18 received percutaneous transhepatic cholangial drainage + stent installation,1 received exploratory lapartomy and the other 88 patients were untreated.Conclusions The diagnosis and differential diagnosis of the space-occupying lesions of the head of pancreas depend on the clinical presentation,medical history,laboratory examination,sonography,computed tomography or magnetic resonance imaging.Individualized treatment plan based on the feature of the tumor and kinds of the lesions combined with intraoperative pathological examination is helpful for selecting the surgical procedures.

Objective Non small cell lung cancer( NSCLC) is a common tumor and the blood of NSCLC patients is generally in a state of high coagulation.However, as a predictor of coagulation, few study has been done on the role of D-dimer level in lung cancer.This article aimed to analyze the prognostic value of plasma D-dimer level in patients with advanced NSCLC and its relation with pulmonary embolism Methods The study collected patients with lung cancer treated in Tianjin Chest Hospital from January 1, 2013 to October 31, 2015.The serum levels of D-dimer were measured by enzyme-linked immunosorbent assay.Based on different lev-els, the patients were divided into high expression group and normal expression group.The relationship between D-dimer level and the prognosis of lung cancer patients were analyzed by Kaplan-Meier method and Log-rank test univariate analysis.T test was used to ana-lyze the difference of D-dimer between patients with and without pulmonary embolism. Results In all the enrolled subjects,103 ca-ses (73.75%) of plasma D-dimer were normal, while 37 patients (26.25%) were elevated.Survival analysis showed that the patho-logical status, tumor size and D-dimer were independent prognostic factors; and the D-dimer in patients with pulmonary embolism was 5.37 ±1.23 μg/mL, while the patients without pulmonary embolism was 0.43 ±0.73μg/mL, D-dimer in patients with pulmonary embol-ism was high than the patients without pulmonary embolism, showing significant difference (P<0.05). Conclusion Plasma D-dimer is an independent prognostic factor for the prognosis of lung cancer, which is obviously higher in patients with lung cancer and pulmonary embolism than in patients without pulmonary embolism.

Objective To examine plasma levels of protease C1 inhibitor (SERPING1) in adult patients with latent autoimmune diabetes (LADA), and their clinical significance thereof. Methods The levels of SERPING1 were detected and compared between LADA, type 1 diabetes (T1DM), type 2 diabetes (T2DM) and healthy control groups. The correlation between plasma levels of SERPING1 and other clinical indicators such as age, disease course, glycosylated hemoglobin (HbA1c), fasting blood glucose (FPG), 2 h postprandial plasma glucose (2 hPG), fasting c-peptide (FCP) and 2 h postprandi-al C peptide (2 hCP) was analyzed. Multi-factor regression analysis and receiver operating characteristic (ROC) were used to evaluate the predictive effect of SERPING1 in LADA at the early stage. Results The level of SERPING1 was significantly higher in LADA group than that of T2DM group and control group (P < 0.05). There was a negative correlation between SERPING1 and FCP, and a positive correlation between SERPING1 and HbA1c, FPG and 2 hPG (P<0.05). There were no significant correlation between SERPING1 and age, disease course and 2 hCP. FCP was analyzed by regression equation (P<0.05), and which was the main influence factor of the plasma level of SERPING1. The area under the ROC curve (AUC) of SERPING1 was 0.613 (P<0.05), 95%CI 0.514-0.712. The optimal cut-point of SERPING1 for early prediction of LADA was 289.71 mg/L, and the sensitivity and specificity were 69%and 48%respectively. Conclusion SERPING1 combined with other indicators will be useful for identifying LADA from T2DM at the early stage.
