Aim To investigate the effect of low molecular N-trimethyl chloride chitosan(LMTC) on the growth of bovine vascular smooth muscle cells(BVSMCs) in vitro. Methods The antiproliferation activities of LMTC were evaluated in BVSMCs by means of crystal violet staining and MTT assay. The morphological changes of LMTC in BVSMCs were observed under transmission electron microscope. Cell survival ratio influenced by LMTC was assessed by flow cytometer. [WTHZ]Results After BVSMCs were treated by LMTC for 72 h,the growth of the cells was inhibited in vitro and was dependent on concentration; there were some changes of apoptosis by transmission electron microscope and flow cytometer. Conclusion LMTC can inhibit the proliferation of BVSMCs and induce their apoptosis.

Objective To explore the acquired deficiencies of vitamin K-dependent coagulation factors in etiology, clinical characteristics and treatment. Methods Retrospective analysis was performed on the data of etiology, clinical manifestations of 45 patients with acquired deficiencies of vitamin K-dependent coagulation factor. All patients were treated with Vitamin K1 10 -40 mg/d, i. v. , for three months. Some patients with severe blooding were additionally treated with fresh freezing plasma or prothromibin complex. Prothrombin time(PT) and activated partial thromboplastic time(APTT) were measured using Stago automatic blood coagulation analyzer before and after treatment. Ⅱ , Ⅶ, Ⅸ and Ⅹ were measured in some patients. Results Among the 45 cases, no certain cause was found in 19 cases (42.2%), anticoagulant rodenticides poison was a common cause ( 11 cases,42.3% ). The main presentations was hemorrhage, the most common bleeding sites were mucosa (77.8%) (35/45)and hematuria (46.7%) ( 21/45 ). After vitamin K1 treatment, PT and APTT had shortened remarkably from ( 110.35 ± 35.36 ) s,(98.91 ±48.98)s to (13.48 ±2. 17)s,(33.25 ±6.95)s,respectively(t=19.10 and 6.19,Ps <0.01)and the activities of factor Ⅱ、Ⅶ、Ⅸ、Ⅹ had rapidly increased from ( 17.48 ± 10.93 ) %, ( 10.23 ± 5.68 )%, ( 11.98 ±4.69)%,(12.93±7.48)% to (70. 12 ±21.31)%,(92.76 ±29. 15)%,(88.64 ±40. 21)%,(63.97 ±20.11)%(t=12.13,14.43,13.27and9. 74,respectively,Ps<0. 01).Conclusions The histories of patients with acquired deficiencies of vitamin K-dependent coagulation factors are usually hiding, therefore it is easily misdiagnosed. It is worth of detecting PT and APTT in diagnosis and monitoring. Using vitamin K1 10 -40 mg/d is effective and safety.

Objective To study the perioperative nursing methods in patients with OSAHS and type 2 diabetes mellitus.Methods From March 2009 to December 2010,a total of 46 patients with OSAHS and type 2 diabetes mellitus were randomly divided into the control group and the experimental group with 23 cases in each group.Conventional care was given to the control group,while the experimental group received systematic,phased and individualized nursing.The sleep quality before and after the operation was compared.The oropharynx wound healing and possible complications,pain were observed after operation.Results In the control group,there was one patient with bleeding during operation,one patient happened blood lost after operation and 2 patients had postoperative infection.The hyperglycemia was found in 3 patients and hypoglycemia occurred in 2 patients.But in the experimental group,all of the patients did not suffer complication.The scores of sleep quality on the day before surgery were significantly higher than those scores on admission,and the scores on discharge from hospital were significantly lower than those scores on admission.There were statistical differences.The scores of the experimental group were significantly improved compared to those of the control group.The score of pain was the highest at the day of surgery,and then gradually decreased.The score of pain of the experimental group was significantly lower than that of the control group,and the difference was statistically significant.Conclusions This comprehensive nursing method during operation period for patients with OSAHS and type 2 diabetes mellitus not only can reduce risk of postoperative complication,but also can improve operation efficacy,quality of nursing and life quality of patients as well as can speed recovery.It approved that this standardized,systematic nursing method during the whole period is practical and effective in OSAHS and type 2 diabetes mellitus treatment and care.

Objective To investigate the effects of ulinastatin on pulmonary and hepatorenal function of elderly patients undergoing resection of esophageal cancer. Methods The clinical data of 40 elderly patients with esophageal cancer who had been admitted to Southwest Hospital from January 2005 to January 2008 were retrospectively analyzed. All the patients were randomly divided into control group (n = 20) and ulinastatin group (n = 20) according to random number table. Patients were administered with total parenteral nutrition, and patients in ulinaslatin group were additionally instilled with 4×10~5 U/d of ulinastatin. The levels of PaO_2, PaCO_2, PaO_2/FiO_2, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (Tbil), blood urea nitrogen, creatinine and uric acid were detected preoperatively and at postoperative day 2 and day 6. All the data were analyzed by t-test and chi-square test. Results The levels of PaO_2 and PaO_2/FiO_2 were (87.3±4.2) mm Hg (1 mm Hg =0.133 kPa) and (416±20)mm Hg in ulinastatin group, which were significantly higher than (79.0±4.3)mm Hg and (376±20)mm Hg in control group (t =6.2, 6.2, P <0.05). The levels of ALT, AST and Tbil were (23±7)U/L, (38±8)U/L and (13.4±3.0) μmol/L in ulinastatin group, and (39±8) U/L, (50±9) U/L and (24.5±6.0) μmol/L in control group, with significant difference between the 2 groups (t = 7.0, 4.4, 7.6, P < 0.05). The levels of uric acid, blood urea nitrogen and creatinine were (279±84) μmol/L, (4.1±1.7) mmol/L and (66±12) μmol/L in ulinastatin group, and (386±67)μmol/L, ( 8.9±2.7) mmol/L and (95±38) μmol/L in control group, with significant difference between the 2 groups (t = 4.4, 6.4, 3.3, P < 0.05). The recurrence of complications in ulinastatin group was significantly lower than that in control group (χ~2 = 4.8, P <0.05). Conclusion Postoperative supplementation of ulinastatin and total parenteral nutrition is helpful in improving the pulmonary and hepatorenal function of elderly patients undergoing resection of esophageal cancer.

A suitable ultra-high performance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS) method was developed for the determination of 11 mycotoxins with isotope internal standard in malt. The mycotoxins in malt were extracted and purified by one-step ultrasonic extraction procedure using acetonitrile/water/acetic acid (80 : 19 : 1), and then detected and confirmed by UPLC-MS/MS, and quantified by isotope labeled AFB1 ([13C17]-AFB1) and ZEN ([13C18]-ZEN) internal standards. Rapid separation of the 11 mycotoxins was successfully achieved on a Phenomenex Kinetex C18 column (100 mm x 2.1 mm, 2.6 μm) with gradient elution using the mobile phase of methanol containing 0.1% formic acid and 2 mmol x L(-1) ammonium acetate in water. Simultaneous acquisition was performed in multiple reaction monitoring (MRM) mode with electrospray ionization (ESI) source operated in both positive and negative ionization modes. The established method provided a good linearity for the 11 mycotoxins within their respective linear ranges with correlation coefficients all higher than 0.999 1. The average recoveries ranged from 75.0% to 117.0% with relative standard deviations (RSDs) below 5.1%. The limits of detection (LODs) and quantitation (LOQs) ranged from 0.05 to 30 μg x kg(-1) and 0.15 to 87.5 μg x kg(-1), respectively, which were below the maximum residue levels (MRLs) set by the European Union. Twenty malt samples were analyzed and nine samples were detected with mycotoxins, which were confirmed according to the same fragment ions found in positive samples and the standards at the same retention time. This study has demonstrated that the one-step extraction procedure of mycotoxins from complex matrices coupled to UPLC-MS/MS method is simple, quick, accurate and sensitive for quantitative and qualitative analysis of multiple mycotoxins in malt.
