Objective:To study the effect of sufentanil combined with dezocine on the PCIA after abdominal operation. Methods:Totally 110 patients undergoing abdominal operation were randomly divided into the experimental group and the control group with 55 cases in each. The two groups were both treated with electronic analgesia pump for the PCIA after the operation. The control group was given dezocine 0. 3 mg·kg-1 ,and the experimental group was given sufentanil injections 0. 1 g·kg-1 plus dezocine 0. 3 mg·kg-1 . The VAS score,adverse drug reactions,Ramesay scores,press number of patient controlled analgesia,exhaust time,recovery time of bowel sounds and bowel audio rate index in the two groups were compared to evaluate the effect of PCIA. Results:All the observed in-dices in the experimental group were significantly better than those in the control group(P<0. 01). The incidence of adverse reactions in the experimental group was significantly higher than that in the control group(P<0. 01). Conclusion:Sufentanil combined with dezocine for the PCIA after abdominal operation shows significantly analgesic and sedative effects,and can notably improve the clinical symptoms,which is worthy of clinical application.

To investigate the immunological activities of the recombinant human phosphatase D2 (rhPLD2) in vitro and in vivo, especially its ability to reduce inflammatory reactions, the cDNA fragment encoding rhPLD2 was cloned into prokaryotic expression vector pET30a by RT-PCR and the recombinant protein rhPLD2 expressed in E.coli was purified from the inclusion bodies, while the anti inflammatory activity of rhPLD2 was determined by the amount of eosinophils in bronchoalveolar fluid(BALF) and blood and the expression of IL-5 and MMP-9 in lung tissues of guinea pig model of chronic asthma. It was found that the rhPLD2 recombinant protein was obtained from human Daudi cells by cloning to E.coli, which contained no membrane-binding site and signal peptide. The cDNA sequence encoded 631 amino acid residues (GenBank Accession Number: AY178289). The purity of the rhPLD2 approached up to 76% with a bioactivity of 50.9745 units/L (0.9212 g/L). In addition, the anti inflammatory effect of rhPLD2 protein could be demonstrated in the guinea pig model of chronic asthma after treatment with rhPLD2 protein, such as down regulation in the expression of the inflammatory cytokine IL-5. It is concluded that the anti-inflammator activity of the recombinant human truncated PLD2 protein produced from the E.coli plasmid can be demonstrated both in vitro and in vivo.

[Objective] To construct a database for the genetic polymorphism of 18 STR loci (D8S1179, D21S11, D7S820, CSFIPO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, VWA, TPOX, D18S51, D5S818, FGA, PentaE, PentaD, SE33) in Hart population from Zhejiang province. To investigate the application of 18 STR loci in the field of paternity testing and prenatal diagnosis. [Methods] Fluorescent dye labeling multiplex STR-PCR, capillary electrophoresis and DNA sequencer GeneScan were adopted in genotyping 598 unrelated samples collected from Han population in Zhejiang province. 18-STR database was established and analyzed. Population comparison was conducted between Han population in Zhejiang province and 8 other population. 15-STR and 18-STR identification system were compared in 497 paternity testing cases. [Results] We observed the distribution of 18 STR loci in Han population meet Hardy-Weinberge equilibrium and was different from other 8 population (X~2 test, P>0.05). Statistical results showed that the heterozygosis (He) ranged from 0.630 to 0.942. The combined power of discrimination was>0.9999999999. Compared with 15-STR identification system, higher paternity index scores and higher exclusion rate were obtained with 18-STR identification system in dual-case paternity test and mutation identification. One trisomy 21 fetus was found in a prenatal paternity test case which had two characteristic genotypes in 2 STR loci of D21S11 and Penta D. [Conclusions] The 18 loci were relatively highly genetic polymorphic in Zhejiang Han population and could be used for paternity testing. Some STR loci could be used in prenatal diagnosis for aneuploidy.
