Objective To assess the effect of video-assisted thoracoscopic thymectomy in treatment of myasthenia gravis (MG) and the factors associated with clinical efficacy. Methods 183 patients with MG who underwent video-assisted thoracoscopic thymectomy from January 2011 to May 2016 were enrolled, and the clinical data were retrospectively analyzed. Therapeutic efficacy was evaluated based on the MGFA. Furthermore, the potential factors associated with the clinical efficacy were analyzed using univariate analysis and Cox's proportional hazards regression model. Results 173 in 183 patients completed the whole follow-up. Among whom, 115 patients achieved complete stable remission (66.5%), 13 patients achieved pharmacologic remission (7.5%), 2 patients achieved minimal manifestations (1.2%), 20 patients had no changes (11.6%), 8 patients showed recurrent MG (4.6%), and 3 patients died (1.7%). Further analysis shown age (RR = 1.53, P = 0.031), pathological type of thymus (RR = 5.84, P = 0.022) and MGFA classification (RR = 3.72, P = 0.028) were main factors associated with the therapeutic efficacy. Conclusions Thoracoscopic expand resection is effective in the treatment of MG patients with satisfactory therapeutic efficacy, and age, pathological type and MGFA type were the main factors associated with the therapeutic efficacy.

A sensitive and selective method using high-performance liquid chromatography coupled with elec-trospray ionization tandem mass spectrometry (HPLC–ESI–MS) to determine the concentration of tor-asemide in human plasma samples was developed and validated. Tolbutamide was chosen as the internal standard (IS). The chromatography was performed on a Gl Sciences Inertsil ODS-3 column (100 mm ? 2.1 mm i.d., 5.0 mm) within 5 min, using methanol with 10 mM ammonium formate (60:40, v/v) as mobile phase at a flow rate of 0.2 mL/min. The targeted compound was detected in negative io-nization at m/z 347.00 for torasemide and 269.00 for IS. The linearity range of this method was found to be within the concentration range of 1–2500 ng/mL (r?0.9984) for torasemide in human plasma. The accuracy of this measurement was between 94.05%and 103.86%. The extracted recovery efficiency was from 84.20% to 86.47% at three concentration levels. This method was also successfully applied in pharmacokinetics and bioequivalence studies in Chinese volunteers.

Electrospray ionization (ESI) and atmospheric pressure chemical ionization (APCI) techniques for liquid chromatography–tandem mass spectrometry (LC–MS/MS) determination of levonorgestrel were evaluated. In consideration of difference in ionization mechanism, the two ionization sources were compared in terms of LC conditions, MS parameters and performance of method. The sensitivity for detection of levonorgestrel with ESI was 0.25 ng/mL which was lower than 1 ng/mL with APCI. Matrix effects were evaluated for levonorgestrel and canrenone (internal standard, IS) in human plasma, and the results showed that APCI source appeared to be slightly less liable to matrix effect than ESI source. With an overall consideration, ESI was chosen as a better ionization technique for rapid and sensitive quantification of levonorgestrel. The optimized LC–ESI–MS/MS method was validated for a linear range of 0.25–50 ng/mL with a correlation coefficient≥0.99. The intra-and inter-batch precision and accuracy were within 11.72%and 6.58%, respectively. The application of this method was demonstrated by a bioequivalence study following a single oral administration of 1.5 mg levonorgestrel tablets in 21 Chinese healthy female volunteers.

When growing and metabolizing through carbon resources of hydrocarbon, Pseudomonas 23-1 produces acidicacid and gas. The amount of acidic acid is 0. 015mol/L The output of gas,which thd main composition is CO2 and CH4, is 20ml/L. The organic acid and gas is the important reasons of decreasing the viscosity, enhancing the flow and improving the product of oil.

This paper reports 17 cases of traumatic bilateral epidural hematomas. The incidence of these cases was 8.7% of all cases of epidural hematoma. The hematomas in 15 cases were across the midline, and in the other 2 cases were at different location on either side. The mechanism and clinical features of bilateral epidural hematomas were discussed. The indications for early diagnosis were stressed.

Pseudomonas 23-1 Can metabolize hydrocarbon to produce the surfactant which is glycolipid outside the cell. The glycolipid, whose content is 1.25g / L, is composed of rhamnose and tencarbon fatry acid. It's critical micella concentration is 200g/L. It has the good ability to emulsify the oil. The main reason of improving the product of oil, decreasing the viscosity and enhancing the flow of oil is the effect of surfastant-glycolipid.

Objective To investigate the association of lipoprotein lipase gene Hind Ⅲ and S447X polymorphisms with metabolic syndrome. Methods PCR-RFLP was used to detect lipoprotein lipase Hind Ⅲ and S447X genotypes in 401 subjects(including 201 controls, 200 metabolic syndrome patients). Results ( 1 ) The levels of waist circumference ( WC ) , hip circumference ( HC ) , waist-to-hip ratio ( WHR ) , body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure ( DBP) , total cholesterol ( TC) , triglyceride (TG), high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C), and fasting plasma glucose (FPG) were significantly different between metabolic syndrome group and control group (all P< 0.05). (2)The frequencies of H+H+ genotype,H+allele,SS genotype, and S allele for metabolic syndrome were all significantly higher than those for controls( H+H+ genotype:66. 5% vs 54.2% ,P=0.012; H+ allele:78.0% vs 71.4%, P=0.031;SS genotype:89.5% vs 77. 1% , P = 0.001; Sallel:94.5% vs 87. 56% , P = 0.001). (3) The levels of WC, HC, WHR, BMI, SBP, DBP, TG, LDL-C, and FPG in H + H-/H-H- genotype were significantly lower than those in H+H+ genotype, HDL-C was significantly higher than that in H+H+ genotype ( all P<0. 05). The levels of WC, HC, WHR, BMI, SBP, DBP, TC, TG, and FPG in SX/XX genotype were significantly lower than those in SS genotype, HDL-C was significantly higher than that in SS genotype ( all P< 0.05). (4)Multi-way logistic regression analysis suggested that risk factors for metabolic syndrome were smoking, drinking, and SS genotype (OR value was 4.289,2.268, and 2. 597, respectively ). (5) Result of interaction analysis among different factors indicated that the risk for metabolic syndrome in smoker with SS genotype was 3. 996 times of non-smokers with SX/XX genotype. Conclusions The lipoprotein lipase gene S447X polymorphism is associated with metabolic syndrome risk in Kazakh, and SS genotype and S allele may serve as genetic risk factors of metabolic syndrome, H + H-/H-H- and SX/XX genotypes yield beneficial effect for lipid and blood pressure. SS genotype and smoking may exist additive effect.

Objective: To observe the characteristics of serum homocysteine (Hcy) distribution and the epidemiological characteristics of high serum level of Hcy (HHcy) in Kazakh population.
Methods: The stratiifed cluster random sampling method was used to investigate 1003 kazakh individuals in Xinyuan county of Xinjiang including 433 male and 570 female, and they were individuals into 5 age groups:①(25-34) years, n=333,②(35-44) years, n=306, ③(45-54) years, n=230, ④(55-65) years, n=90, ⑤>65 years, n=44. The questionnaire survey, physical check-up and blood biochemical examination were performed and compared among different groups.
Results: ① The geometrical mean of Hcy was 13.3μmol/L, and the male was higher than female as 16.0μmol/L vs 11.6μmol/L. ②By age stratiifcation, the serum levels of Hcy elevated with the increased age accordingly. Except for those with the age>65 years, the serum levels of Hcy were all higher in male than female in other 4 age groups. ③The average rate of HHcy prevalence was 31.5%, and the male was higher than female as 49.9%vs 17.5%.④The average rate of H type hypertension prevalence was 35.1%, and the male was higher than female as 44.3%vs 28.1%.
