Objective To observe the effects of dexmedetomidine on inflammatory responses and insulin resistance during cardiac operations with cardiopulmonary bypass(CPB).Methods Fifty patients scheduled for elective cardiac valve replacement with CPB were equally and randomly divided into two groups using a random number table:observation group and control group(n =25).A loading dose of dexmedetomidine 1.0 μg/kg was injected intravenously over 1 5 min after induction,followed by continuous infusion at 0.4 μg·kg-1 ·h-1 until the end of CPB in doservation group.While the e-qual volume of normal saline was given in control group.After induction(T1 ),at 30 min after the be-ginning of CPB(T2 ),at the end of CPB(T3 ),and at 2 h after the end of CPB(T4 ),the jugular venous blood samples were taken for determination of serum concentrations of TNF-a,IL-6,insulin and blood glucose.The insulin sensitivity index (ISI ) = 1/(glucose × insulin )was obtained. Results Compared with control group,the serum TNF-a and IL-6 concentrations at T2-T4 were sig-nificantly decreased in observation group(P <0.05),the serum insulin and blood glucose concentra-tions at T2 ,T3 were significantly decreased in observation group(P <0.05 ),the ISI at T2 ,T3 were significantly increased in observation group(P <0.05).Conclusion Dexmedetomidine can reduce in-flammatory responses,thus reducing insulin resistance and blood glucose during cardiac operations with CPB.

Objective:To establish an HPLC method for the determination of genistein in genistein-loaded Eudragit nanoparticles. Methods:The HPLC analysis was carried out on a DiamonsilTM C18(250 mm ×4.6 mm,5μm)column with the mobile phase of meth-anol-water (85∶15) at the flow rate of 1. 0 ml·min-1 . The detection wavelength was set at 261nm and the column temperature was 25℃. Results: A good separation was displayed between the drug peak and the excipient peaks. An excellent linearity range for genistein was obtained from 1.0 μg·ml-1 to 100.0 μg·ml-1(r =0.999 8). The recovery of genistein was 99.85%(RSD =0. 65%,n=9). Conclusion:The method is simple, rapid, accurate and specific, which is suitable for the determination of content and encapsulation efficiency of genistein-loaded nanoparticles.

OBJECTIVE:To provide reference for developing the implementation path of patent standardization for pharmaceuti-cal industry. METHODS:For the situation that pharmaceutical industry is still in the exploratory stage and lacks of viable experi-ence,the mature experiences of electronic communication industry in patent leading standardization implementation,authoritative organizations helping implementing patent standardization and industry alliance to promote the development of patent standardiza-tion were used as reference,combining with standard development cycle,trying to develop the implementation path of patent stan-dardization that met characteristics of pharmaceutical industry. RESULTS & CONCLUSIONS:The implementation path of patent standardization for pharmaceutical industry was divided into standard formation stage,promotion stage and upgrade stage. The main path in each stage was from patent to registration standards officially formed,guiding by policies and regulations of Food and Drug Administration to conduct standard promote by drug generation,and upgrading the drug standard by patent replacement.

Objective To observe the effect of silencing Snail gene on the invasion and proliferation ability of human pancreatic cancer cell line PANC1.Methods Lentiviral vectors that can express small hairpin RNA(shRNA) targeting human Snail gene(shRNA-Snail) or shRNA sequence that did not match any known mRNA(shRNA-NC) were constructed,and transfected into PANC1 cells.Untransfected cells served as control.mRNA and protein expression of Snail,α-smooth muscle actin (α-SMA) and E-cadherin was determined by real time quantitative PCR and Western blotting,respectively.In vitro invasion ability was tested by Transwell model.Proliferation ability was measured by CCK-8 assay.Results Compared with those in shRNA-NC group,Snail mRNA (0.27 ± 0.02 vs 0.92 ± 0.03) and protein level (0.26 ± 0.02 vs 0.80 ± 0.02),and α-SMA mRNA (0.33 ±0.04 vs 0.97 ±0.07) and protein level (0.31 ±0.04 vs 0.74 ±0.06) in shRNA-Snail group were obviously decreased,but E-cadherin mRNA (1.57 ± 0.45 vs 0.95 ± 0.08) and protein level (0.86 ± 0.03 vs 0.20 ± 0.03) were greatly increased.The number of cells permeating the septum of transwell [(6.80 ± 0.73)/400 magnification vs (26.80 ± 2.52)/400 magnification,P ＜0.01] was significantly decreased,and cell proliferation was inhibited (0.74 ± 0.05 vs 1.47 ± 0.04,P ＜ 0.01).All the differences above were statistically significant (all P ＜ 0.01).No significant differences were observed between shRNA-NC and normal control group.Conclusions Silencing Snail gene may restrain the invasion and proliferation ability of PANC1 cells to a certain degree.

Objective To determine the expression of TM4SF1 mRNA in 5 human pancreatic cancer cell lines,and investigate its effect on the proliferation,migration and invasion of pancreatic cancer cells.Methods The expression of TM4SF1 mRNA in MPanc96,MiaPaCa-2,PANC1,AsPC-1,HPAC cells was determined by qRT-PCR,and the results were compared with that of human pancreatic ductal epithelial (HPDE) cells.RNA interference method was used to transiently transfect siRNA targeting at TM4SF1 and negative control siRNA into MPanc96,MiaPaCa-2 cells.The proliferation of cells were measured by MTS method,and migration and invasion of cells were determined by Transwell.Results The expression levels of TM4SF1 mRNA in pancreatic cancer cell lines MPanc96,MiaPaCa-2,PANC1,AsPC-1 and HPAC were 1.205 ± 0.073,1.096 ± 0.260,1.382 ± 0.075,1.374 ± 0.363 and 0.744 ± 0.096,which were significantly highly than that in HPDE (0.020 ± 0.003,P ＜ 0.01).Compared with cells transfected with negative control siRNA,the proliferation of MPanc96 and MiaPaCa-2 cells transfected with siRNA targeting at TM4SF1 was not significantly changed,but the migration abilitiy was decreased by (62.5 ± 7.6) ％ and (72.8 ± 4.0) ％,and invasion abilitiy was decreased by (69.5 ± 5.7) ％ and (78.6 ± 6.3) ％.Conclusions TM4SF1 is highly expressed in pancreatic cancer cells and appears to promote the migration and invasion abilities of the cancer cells.
