Objective To observe the preventive efficacy and safety of dexmedetomidine with parecoxib sodium on the patients with postoperative hyperalgesia induced by remifentanil. Methods A total of 100 female patients undergoing elective surgery under general anesthesia were as-signed into four groups according to the table of random number:the control group (group C),the parecoxib sodium group (group P),the dexmedetomidine group (group D)and the parecoxib sodium combined with the dexmedetomidine group (group DP).The vital signs were monitored and the total intravenous anesthesia was performed.All the patients were give intravenous injection of 0.2μg·kg-1 ·min-1 remifentanil and 4-12 mg·kg-1 ·h-1 propofol to maintain the anesthesia.Patients in group P were given 40 mg parecoxib sodium 30 minutes before the end of the operation.Patients in group D were give intravenous injection of 0.6μg·kg-1 ·min-1 dexmedetomidine consistently till 30 min before the end of the operation.Patients in group DP were given 0.6 μg·kg-1 ·min-1 till 30 min before the end of the operation and were given 40 mg parecoxib sodium.The VAS scores were re-corded at 1,2,6,12,24 hours.The cases of agitation,rigors,nausea and vomiting and increasing of analgesics were recorded.Results The postoperative VAS scores in group P,group D and group DP were significantly lower than group C(P <0.05).The postoperative VAS scores in group DP were significantly lower in group P and group D (P<0.05).Cases of agitation and rigors in group D and group DP were less than group C(P <0.05).The increasing of analgesics in group DP was much higher than other groups(P<0.05).Conclusion After induced,patients were given intravenous in-jection of 0.6 μg·kg-1 ·min-1 dexmedetoniding consistently till 30 min before the end of the opera-tion were given 40 mg parecoxib sodium can effectively prevent hyperalgesia after remifentanil anes-thesia without significant increase in revival time and obtain a better sedation.

Background Age-related cataract is one of the common causes of blindness.Although the pathophysiology of age-related cataract is far from clearly understood,it is well accepted that DNA damage plays an important role in the disease pathogenesis.Objective The purpose of this study was to quantitatively evaluate the DNA damage in peripheral lymphocytes of age-related cataract.Methods A cross-sectional study was carried out.This study complied Declaration of Helsinki and approved by Ethic Committee of Affiliated Hospital of Nantong University.Written informed consent was obtained from each subject.Two hundred and eleven patients with agerelated cataract and 147 normal subjects were enrolled from a “ Jiangsu Eye Study:Funing 2011 Eye Disease Epidemic Survey”.All the subjects aged from 50 through 80 years with matched age and gender between the two groups.The percentage of tail DNA and Olive tail moment (OTM) were detected by comet assay to assess the extent of DNA damage in peripheral lymphocytes.Statistical analyses were performed with SPSS 17.0 software,and the differences of the percentage of tail DNA and OTM were compared between the age-related cataract group and normal control group by independent sample t test as well as among the 50-59 years group,60-69 years group and ≥70 years group by one-way analysis of variance.Results Comet assay showed a round lymph cell with the clear border in the normal group;while in the age-related cataract group,the cell was bigger with a comet-like tail.The percentage of tail DNA and OTM in peripheral lymphocytes were (21.75 ± 3.51) ％ and 6.54 ± 1.65 in the age-related cataract group,and those in the normal control group were (9.31 ±3.60)％ and 2.18 ± 1.10,respectively,with significant differences between them (t =32.67,P =0.00 ; t =28.02,P =O.00).In the 50-59 years subgroup of the age-related cataract group,the percentage of tail DNA and OTM in peripheral lymphocytes were (20.04±2.86) ％ and 5.92± 1.14,and in the 60-69 years subgroup of the age-related cataract group,the percentage of tail DNA and OTM in peripheral lymphocytes were (20.77 ±2.93) ％ and 6.13 ± 1.14,which were significantly reduced in comparison with (22.79 ± 3.67)％ and 6.95±1.91 of the ≥70years subgroup(TailDNA％:q=2.75,P=0.00; q=2.02,P=0.00;OTM:q=1.03,P =0.02 ; q =0.82,P =0.00).Conclusions The pathogenesis and development of age-related cataract probably is associated with DNA damage.

0.05).At different time points after ischemia-reperfusion,the expression of cytochrome C and activation of caspase-3 were lower in the transgen mice than that in the wild type rats.Conclusions Under standard condition,overexpression of bcl-xl could significantly reduce the infarct area and improve neurological function in transgene mice than those in the wild type rats.The effect of overexpression of bcl-xl might be realized through inhibiting the apoptosis of neuron,and the mechanism might be that the overexpression of bcl-xl inhibit the release of cytochrome C and the activation of caspase-3.

Objective:Increased reactive oxygen species (ROS) formation and by which in turn promotes cardiomyocytes apoptosis is associated with the pathogenesis and progression of various cardiac diseases. Small heat shock protein 27(Hsp27) could protect different cells from oxidative damage. By using tissue nonspecific overexpression Hsp 27 transgenic model, other investigators demonstrated that Hsp27 suppressed successfully kainate-induced seizures and hippocampal cell death in intact transgenic mice, and attenuated mimic ischemia/reperfusion injury in Langendorff-perfused isolated mice heart. As there are complicated and long distance neuro-humoral regulation associated with the development of cardiac diseases, it is better to choose a cardiac-specific overexpression transgenic model to study the effects of Hsp27 in hearts in vivo.Methods:A cDNA encoding human Hsp27 was subcloned into pBSII-SK+ containing the ?-myosin heavy chain (?-MHC) promoter (generously provided by Dr. J. Robbins, Children’s Hospital of Cincinnati, Ohio). BamHI-digested linear transgene consistent with the ?-MHC promoter, Hsp27 cDNA, and poly (A) of human growth hormone (hGH) was microinjected into the fertilized eggs from CBA/BL6 mice. Mice containing the transgene were identified by polymerase chain reaction. Founders revealed by this screening were used to establish independent transgenic lines. Following successful transmission, a range of tissues including heart, lung, liver, brain, skeleton muscle, spleen and kidney was screened by Western blot to confirm the cardiac specific expression of the transgene. Results and Discussion:Transgenic mice expressed Hsp27 under the control of a-MHC promoter. Cardiac tissues from independent TG line expressed abundant Hsp27, and as expected, Hsp27 expressed in cardiac tissues only, whereas none in liver, spleen, lung, kidney, brain and skeleton muscle. Surprisingly, Hsp25, the endogenous isoform of Hsp27 in murine, was downregulated by Hsp27 overexpression (data not shown), which is in contrast to the result of Hollander’s [1]. It needs to determine in future whether Hsp27 expression profile in heart could exert any effect on the regulation of Hsp25.Conclusion: The TG mice overexpression human Hsp27 specifically in the heart by using ?MHC- promotor were created. All TG mice expressed Hsp27 abundantly and cardiac-specifically. To our knowledge, it is the first report of creation of transgenic mice which overexpressing Hsp27 cardiac specifically. This current model suggests that the Hsp27 cardiac-specific over-expression of transgenic mouse remains a robust genetic tool for dissecting molecular and genetic events involving Hsp27, which could be a therapeutic target in heart failure.

To propose a formula method of medicated diet based on medicinal property combination patterns in this paper under the context of lack of innovation in medicated diets. By analyzing the property combination patterns of traditional Chinese medicine and commonly used foods recorded in the pharmacopoeia, medicated diet formulae were optimized by using the greedy algorithm, with the property combination patterns of classical formulae based on the syndrome differentiation and treatment. In this paper, the Baihu Rensheng decoction, which is a classical formula for treating lung and stomach heat-derived diabetes, was taken for example in the formula design. As a result, totally 18 medicated diet formulae were developed and proved to be rational in the analysis on traditional Chinese medicines and nutriology. This method expands the way of thinking for personalized diet therapies and provides theoretical basis the industrial development and clinical application of medicated diets.

Objective To determine the effect of mitochondria on the protection of heat-shock proteins B1(HSPB1) from oxidative damage in rat cardiac cell.Methods HSPB1 gene-transfected rat cardiomyocytes cell line H9c2 (HSPB1 H9c2) and empty vector transfected H9c2 (control) were established,and treated by 0-1000?mol/L H_2O_2 for 2h.And then the cell morphology, mitochondrial membrane potential and endogenous reactive oxygen species (ROS) were detected. Results (1)HSPB1 inhibited the morphological changes induced by H_2O_2 markedly.(2)HSPB1 inhibited the loss of mitochondrial membrane potential induced by H_2O_2.Following the stimulation of 0,75,150,300,500,1000?mol/L H_2O_2,mitochondrial membrane potential in HSPB1 and control H9c2 cells were (10.0?0.11)vs (7.01?0.26),(9.11?0.17)vs (6.05?0.19),(7.69?0.28)vs (5.14?0.28),(6.95?0.13)vs (4.66?0.11),(6.61?0.20)vs (1.85?0.35),(6.60?0.05)vs (1.19?0.01),respectively (all P0.05).Conclusions HSPB1 protects rat cardiomyocytes cell line(H9c2) from oxidative damage,which suggests that stabilization of mitochondrial membrane potential and the decreased endogenous reactive oxygen species after oxidative stress may be involved in the protection of HSPB1 against oxidative stress in H9c2.
