Journal of Kunming Medical University 2013;(9):46-50
Objective To study the changes of SUR1-regulated NCCa-ATP channels in core area during focal cerebral ischemia and reperfusion in rats, and to explore the therapeutic window of focal cerebral ischemia. Methods Adult male Wistar rats were rendered to undergo 120 minutes of the left middle cerebral artery occlusion (MCAO) by the intraluminal thread technique before reperfusion. The core area of the left hemisphere cortex ischemia/reperfusion at different times (reperfusion:R3 h, 6 h, 8 h, 12 h and 24 h) was taken to be tested the level of mRNA and protein expression of sulfonylurea receptor 1 (SUR1) using RT-PCR and Western-blot techniques. SUR1 of the ischemic brain microvascular endothelial cells were observed by immunofluorescence double staining at the peak expressing time point of SUR1. Results We found the up-regulation of SUR1 mRNA and SUR1 protein in ischemic infarcts tissues for R3 h, 6 h, 8 h and 12 h, peaked at R8 h, compared with the sham-operation group ( <0.05) . However, SUR1 expression increased was observed at R12 h by double immunofluorescence in microvascular endothelium. Conclusion SUR1-regulated NCCa-ATP channel may take part in cerebral ischemic damage during focal cerebral ischemia and reperfusion. The expressions of SUR1 mRNA and SUR1 protein were up-regulated in ischemic infarcts tissues. The data suggested that the best time to apply SUR1 inhibitor is within 8-12 hours after ischemia and reperfusion.

Objective:To establish a method for the content uniformity ( CU) of fennel oil in Weitongning tablets to study the CU of fennel oil in Weitongning tablets. Methods: Methyl salicylate as the internal reference, the content of trans-anethole in fennel oil was determined by GC. The separation was performed on a DB-FFAP capillary column (30 m × 0. 32 mm, 0. 25 μm) at 145℃, the injection part temperature was 180℃ and the FID detector temperature was 230℃, nitrogen with high purity was used as the carrier gas at the flow rate of 0. 8 ml·min-1 . The air flow rate was 400 ml·min-1 and that of hydrogen was 35 ml·min-1 . The methodology validation was carried out, and the samples from different companies with different batches were determined. Results:Significant differ-ence showed in the CU of fennel oil in the samples with different batches from the same manufacturer or from different companies. The trans-anethole showed linear correlation within the range of 2. 189-35. 030 μg · ml-1 ( r =0. 999 9 ) and the average recovery was 100. 06% (RSD=0. 5%, n=9). Conclusion:The method is simple and quick. It is accurate in the CU determination of fennel oil and can be used for the quality control of Weitongning tablets.

Chinese Journal of Diabetes 2015;(4):345-348
Objective To explorethe relationship between serum uric acid (SUA ) and transcutaneousoxygenpressure(TcPO2)inpatientswithT2DM.Methods 622hospitalizedpatients with T2DM were recruited and divided into high SUA (HUA) group and normal SUA (T2DM) group.The differences in TcPO2 (initial value ,stable value ,initial value‐stable value ,leg‐raising initial value and leg‐raising maximum value)were compared between two groups.The correlations between SUA and TcPO2 were evaluated. Results The levels of TcPO2 were lower in HUA group than in T2DM group [initial value:left (34.05 ± 13.17) vs (39.26 ± 15.82) ,right (34.71 ± 14.90) vs (40.15 ± 16.23);stable value:left (38.93 ± 12.23) vs(45.19 ± 13.40) ,right (39.98 ± 12.34) vs (45.90 ± 16.77) ,P<0.05]. Pearson correlation analysis showed that the SUA levels negatively related with the stable TcPO2 value of leftor right side ,and with the change between the initial value and the stable value of TcPO2 (P<0.05 or P<0.01). The multiple linear regression analysis showed that SUA level was the impact factorof the left TcPO2 stable value. Conclusion HUA may be one of the risk factors microcirculation disorder in T2DM patients.

OBJECTIVE:To construct surgery base drug management system,and to realize efficient and accurate drug man-agement in surgery room. METHODS:The functions of surgery base drug management system exploited by our hospital were intro-duced,and the effect of the system was evaluated in department of anesthesiology. RESULTS&CONCLUSIONS:The system pos-sesses the functions of surgery drug automated affiliated charge,standardized narcotics prescription autogeneration,discarded nar-cotics prescription auto-prescribing,and drug information summary statisticing and checking,etc. After the application of the sys-tem,nonstandard rate of prescription decreased from 12.7% of handwritten prescription to 0.1% of electronic prescription;the time of drug requisition and checking decreased from(8.5±1.6)min to 0 min and(7.6±1.0)min to(2.9±0.9)min(P<0.05 or P<0.01). The system standardizes medication behavior of physicians and improve their work efficiency,avoid the loophole of drug charge management,realize the consistency between the accounts and the real numbers of narcotics,improve the rate of quality pre-scriptions and narcotics management, and realize integration,automation,intellectualization and whole-course supervision of drug management in pharmacy and clinical departments.

With the development of world-wide integration in the field of education and under the Bologna Process of Russia, Russian high medical colleges have begun actively searching a new way to reform medical education. However, they have encountered many problems due to the unique feature of Russian higher medical education. To analyze those problems will help us to deepen the understanding of Russian high medical colleges and strengthen Sino-Russia exchanges and cooperation.

Orthopedic Journal of China 2006;0(08):-
[Objective]To explore the effective treatment method of the articular fracture in distal radius.[Method]Severely comminuted AO type-C3 intra-articular fractures of the distal end of the radius were treated with combined internal and external fixation.The Gartland and Werley system and the Green and O'Brien system were used for comparison of the pre-operative and after operative evaluation.Total articular congruity had been assessed with both clinical rating systems.[Result]At a mean of ninteen months following-up,the mean arc of flexion-extension was 78% of that on the uninjured side and the mean grip strength was 82% of that on the uninjured side.The mean total articular incongruity(the gap plus the step-off)averaged 2 mm,and the radial length was restored to a mean of 11 mm.According to the Gartland and Werley demerit-point system,seventeen of the patients had a good or excellent result.According to the modified Green and O'Brien clinical rating system,eleven had a good or excellent result.Postoperative total articular incongruity had a moderately strong correlation with the outcome as assessed with both clinical rating systems.[Conclusion]Open reduction and combined internal and external fixation of AO type-C3 fractures can restore radiographic parameters to nearly normal values,maintain reduction throughout the period of fracture-healing,and provide satisfactory functional results.

An acidic xylanase gene,named xyl3,was cloned from the genomic library of enviromental microbes constructed by using shotgun cloning strategy,and submitted to GeneBank with accession number of gb:AY300805.BLAST analysis indicated that the gene xyl3 has low similarity with other xylanase genes and the encoded xylanase,sorted as Glycosyl hydrolases family 10,has 77% similarity with the intra-cellular xylanase from Geobacillus stearothermophilus at amino acid level.Treated with T4 DNA polymerase,the gene xyl3 was ligated with the linearized Pichia pastoris expression vector pHBM905 produced by digestion of restriction endonuclease CpoI and NotI to generate the recombinant plasmid pHBM706.Then the plasmid pHBM706,digested by restriction endonuclease SalI,was transformed into P.pastoris GS115 to obtain the recombinant P.pastoris GS115(pHBM706),which was induced to produce the recombinant xylanase with 0.5% methanol at 28℃.At the 36th hours of induction,the porduced crude enzyme was detected to reach the higest enzyme activity of 0.177 IU/mL.The optimal pH and temperature of the enzyme activity is 5.5 and 50℃ respectively.
