Objective This study was designed to analyze the proteome differences between cancer tissue and surrounding-cancer tissue using Two-Dimensional Gel Electrophoresis (2-DE) in patients with HBV relative HCC.Methods Immobile phase pH gradients (IPGs) for isoelectric focusing of proteins were used as the first dimension,and SDS-polyacrglamide gel electrophoresis(PAGE) as the second dimension. The gels were stained by silver, scanned by ImageScanner, analyzed with ImageMast software.Results Average spots expressed in cancer tissue,cirrhosis tissue and chronic hepatitis tissue were significantly different(P

Objective:To analyze and evaluate the degassing effect of vacuum degassing apparatus through the determination of ox-ygen content in pure water, gas pressure and air volume, and compare with suction filtration, boiling and ultrasonic methods to choose the appropriate degassing method for dissolution medium and guide the daily inspection work. Methods: The water residual oxygen, gas pressure and air volume were determined using a single water quality on-line monitoring instrument and a Carbo QC Anton Pear in-strument. The degassing effect of the vacuum degassing apparatus was detected under the conditions of negative pressure and certain de-gassing time. The degassing effect was also compared with that of suction filter, boiling and ultrasonic methods. Results: Under the conditions of 0. 06 MPa negative pressure, 41℃ medium temperature and 30 min degassing time, the degassing effect of the vacuum degassing apparatus was obvious. The degassing effect of suction filter and boiling methods was similar to that of the vacuum degassing apparatus, while that of ultrasonic method wasn't obvious. Conclusion:The use of vacuum degassing apparatus is simple and efficient with obvious degassing effect, which is suitable for the degassing process of dissolution medium.

Objective To establish a polarographic method for detecting fluoroacetamide.Methods On the condition of strong basic solution with high temperature fluoroacetamide was decomposed to form a decomposed product ALC-La-F - complex.In a pH4.90buffer solution containing KNO 3 and hexamethylenetetramine,the decomposed product was determined with com-plex-adsorptive wave at-0.67V by polarography.Re sults The detection limit and linear range of the method was2.0?10 -8 mol/L and5.0?10 -8 -1.2?10 -6 mol/L respectively.The regressive equation was y=3.49x+0.042with a correlation coefficient r=0.9996.The method had been applied to the determination of fluoroacetamide in wheat flour samples satisfyingly.Conclu-sion This method was simple and suitable for the determination of fluoroacetamide in flour.

OBJECTIVE:To provide reference for rational use of human serum albumin for surgical inpatients. METHODS:The utilization of human serum albumin for surgical inpatients in a hospital during Jan.-Mar. 2014 was analyzed and evaluated by UHC Guidelines for the Use of Album,Nonprotein Colloid,and Crystalloid Solutions(2010 edition)and European Immune Globu-lin and Albumin Use Recommendation. RESULTS:Among the 556 patients,totally 895 human serum albumin application were con-ducted,mainly involving development of gastrointestinal surgery(29.7%),hepatobiliary surgery(25.9%)and cardiothoracic sur-gery(13.1%). The main reasons were correcting hypoalbuminemia(62.9%),followed by albumin supplemented during major sur-gery(7.9%)and alleviating ascites in patients with cirrhosis(4.4%);only 95 applications(10.6%)were considered appropriate. The most prevalent inappropriate reason was for correcting hypoalbuminemia. CONCLUSIONS:Human serum albumin in the surgi-cal inpatients in the hospital shows a large amount,and low consistent rate between indications and guidelines. The rational stan-dardized utilization of human serum albumin should be strengthened.

AIM: To survey the pathogenesis, clinical characteristics and surgical treatment for the correction of A-pattern exotropia.METHODS: The case history and surgical effect of 62 A-pattern exotropia in 1825 strabismus were studied. The superior oblique muscles weakening or the horizontal muscles procedures were performed in all patients according to the dysfunction of the superior oblique muscles, horizontal deviation, with or without binocular vision. Follow-up after surgery was 6-18months with mean duration of 9 months.RESULTS: A-pattern exotropia accounts for 3.4% of all strabismus. A-pattern exotropia accounts for 21.2% of A-V syndrome. After surgery, 52 cases got alignment, 56 cases gained A-sign correction and 54 cases recovered binocular vision.CONCLUSION: A-pattern exotropia is a common type in strabismus, its etiology is mainly oblique muscle dysfunction.Different surgical procedures should be selected according to overaction degrees of oblique muscle and binocular vision function, which can acquire the satisfied results.

Objective: To establish the quality standards for Jifukang Oral Solution. Methods: Fructus Corni, Fructus Ligustri Lucidi, Herba Epimedii were identified by TLC, and the content of astragalin A was determined by TLC scanning. Results: The Fructus Corni, Fructus ligustri licidi, Herba Epimedii could be identified by TLC. Astragalin A showed a good linear relationship at a range of 1.065～5.325?g,r=0.9991. The average recovery was 95.1%, and RSD was 2.0%. Conclusion: The methods are accurate and can be used for the quality control of Jifukang Oral Solution.

Objective To investigate the effects of dexmedetomidine on hemodynamics and tra-cheal intubation facility in general anesthetized patients.Methods Forty gynecological patients of se-lective operation under general anesthesia were randomly arranged into 2 groups:group D and group C.With high flow mask oxygen inhalation(5 L/min),dexmedetomidine was intravenously pumped in-to the patients in group D at 0.6μg/kg in 10 minutes while in group C saline were given instead.Both groups were then proceeded with rapid sequence induction (RSI)immediately.The values of MAP, HR,PaO2 and PaCO2 were recorded every minute from pumping start till 15 minutes,the bucking, intubation time and glottis exposure were evaluated as well.Results No significant differences were found in intubation time or glottis exposure between these two groups.After tracheal intubation group D showed higher MAP value than group C at 14,15 minutes,and a lower HR value (P <0.05).Even no significant differences were found in values of SpO2 and PaO2 ,the group D showed less bucking than the group C (P<0.05).Conclusion Dexmedetomidine administration at 0.6μg/kg in RSI can diminish the variation in hemodynamics and facilitate the tracheal intubation by less buc-king,but no affect the oxygen reserve.

0.05).CONCLUSIONS There is high frequency of C.albicans in the elderly.There is no significant difference rate of detection rate among three groups.Mucosa swab sampling method may be a convenient and effective method for clinical study.

Objective To explore the effects of piperine on cell proliferation and migration in angiotensin Ⅱ (Ang Ⅱ)-treated rat airway smooth muscle cells (ASMCs).Methods The primary ASMCs of rats were cultured by improved tissue-piece digestion inoculation and trypsin digestion.MTT assay was used to detect the effects of Ang Ⅱ and Ang Ⅱ receptor antagonist losartan on cell proliferation activity.After treatment with Ang Ⅱ and piperine, the cell proliferation activity, the cell cycle distribution and the cell migration were detected by MTT, flow cytometry and Transwell assay respectively.ERK1/2 inhibitor PD98059 and losartan were then applied to determine the expression of cyclin D1, MMP-9, p-ERK1/2, ERK1/2, and β-actin proteins by Western blot assay.Results After 24 h culture, Ang Ⅱ treatment promoted the cell proliferative activity in rat ASMCs (P<0.05), and the promotive effect of 10-7 mol/L Ang Ⅱ was the most significant.Additionally, losartan blocked the Ang Ⅱ-induced cell proliferative activity in rat ASMCs (P<0.05).10-7 mol/L Ang Ⅱ treatment resulted in the elevated cell proliferative activity, higher S phase fraction, increased migrated cell number, and enhanced expression of cyclin D1, MMP-9and p-ERK1/2 proteins (P<0.05);these effects were dose-dependently reversed by piperine.Both PD98059 and losartan blocked Ang Ⅱ-induced expression of p-ERK1/2, cyclin D1 and MMP-9 proteins in rat ASMCs.Conclusions Piperine may inhibit Ang Ⅱ-induced cell proliferation and cell migration via ERK1/2 signaling pathway in rat ASMCs.
