Objective To investigate the effect of desflurane anesthesia on the autonomic nervous system in patients at high risk for coronary artery disease.Methods Thirty patients at high risk for coronary artery disease scheduled for elective abdominal operation were selected. Heart rate variability (HRV) was assessed at preoperation, inhalation of 05,10,15 and 20 MAC of desflurane with Holter electrocardiography Results Low-frequency component increased markedly inhaling low concentration of desflurane. With the increase of the concentration of desflurane, both the high-frequency and low-frequency components decreased significantly (P0 05).Conclusions Desflurane balanced anesthesia dose not increase the activity of sympathetic nervous system.

Long-term tachycardia may cause tachycardiomyopathy(TCM),clinical manifestation is similar to the dilated cardiomyopathy.But,after treatment,cardiac function can be partially or completely recovered.By the explanation of definition,etiology,pathogenesis,diagnosis and treatment progress of TCM,the aim of the thesis is to enrich the knowledge of clinician about the diagnosis and treatment of TCM.

Objective:To explore the propagable experience and methods of controlling the rate of cesarean sec-tion through the summary of the innovative measures in four counties. Methods:The cases of natural birth and cesare-an section from 2009 to 2013 in four counties were analyzed respectively. The interventions of controlling cesarean section rate have been summarized. Results:The average cesarean section rate of four counties in five years is on the decline, since 2009 the rate were 60. 2%,62. 3%,59. 3%,51. 4%,48. 1%. Conclusions: The interventions really worked, but did not do the best. Improving the social attention on these innovative measures, strengthening surveil-lance mechanism, regulating the medical behaviors of delivery hospitals, enhancing the midwifery training and promo-ting the interventions under the coordination of local government can further reduce the rate of cesarean section.

Toxoplasma gondii is a globally distributed Apicomplexan Protozoa which can infect all warm-blooded animals and cause serious diseases in immunocompromised host.More attention has been paid to wide distribution and opportunistic pathogenesis of T.gondii.This paper is summarized the history,the lastest hotspots in Toxoplasma and future challenges in toxoplasmosis control.

Objective To express P38 of Schistosoma japonicum in Escherichia coli BL21 and develop the monoclonal antibodies (McAb) against rSjP38. Methods The recombinant plasmid pET32(a)-P38 was transformed into E.coli BL21(DE3). 1 mmol/L IPTG (isopropyl-beta D-thiogalactopyranoside) was used to induce the expression of the recombinant rSjP38. The rSjP38 was soluble in supernatant after sonication and further purified by His-Ni chromatography. BALB/c mice were immunized with the purified rSjP38 and hybridomas were generated with traditional technique. McAbs were screened by ELISA with limited dilution. The subtype and specificity of McAb were identified by kit and Western blot respectively. Results Eight hybridoma cell lines secreting monoclonal antibodies to rSjP38 were obtained. The subtype of all the 8 McAbs are IgG1. Western blotting showed that the 8 McAbs reacted strongly and specifically with native antigen (P38) of Schistosoma japonicum. Conclusions Eight hybridoma cell lines secreting highly specific McAbs against P38 have been established.

Objective:To prepare and identify the monoclonal antibody against hPPAR?2.Methods:cDNA of hPPAR?2 was obtained from pMD18-T/hPPAR?2.hPPAR?2 was expressed in prokaryocyte and purified successfully.The anti-hPPAR?2 monoclonal antibodies (mAbs) 1B4,3H2,3H10,10D6 and 10D8 were produced by immunization with purified hPPAR?2.The specificity of the antibodies was identified by ELISA,Western blot assay and immunocytochemistry.Results:Five novel murine monoclonal antibodies only against hPPAR?2 were harvested,and they were all specific to hPPAR?2.Conclusion:The antibodies obtained provide more useful tools for following research and settling the basis for screening new drugs and mechanism.

Retinopathy of prematurity (ROP) is a potentially blinding retinal vascular disease that occurs in premature infants and low birth weight infants.Along with the development of perinatal medicine,the incidence of ROP has increased.If infants with ROP could get treatment in time,the disability rate due to ROP would significantly reduce.Now,the present situation and advances in treatment of ROP were reviewed.

500 thousands people died from gastric cancer in China over 2015,shortage of clinical medicines and therapeutic methods is one of the reasons for the high mortality.Tumor immunotherapy is the hottest area of research over the past decade,whose success in hematological malignancies makes people raised their confidence to “cure” cancer.In recent years,gastric cancer immunotherapy research has made some achievements,while clinical outcomes still need improvement.In this paper, the progress of clinical research of common immunotherapeutic drugs and methods in several fields of gastric cancer research are reviewed to discuss the development prospects of immunotherapy for gastric cancer .

As a member of PARP superfamily, PARP3 shares a high homology with PARP1 and PARP2, which are all DNA-dependent enzymes that are catalytically activated by DNA strand breaks.Compared to PARP1 and PARP2, PARP3 exerted some special properties in tissue expression pattern and biological function.The evidence has shown that PARP3 could be activated by DNA double strand breaks and special DNA single strand breaks and synthesize mono(ADP-ribose) (MAR) covalently attached to target proteins including itself.PARP3 plays an important role in DNA double strand breaks, DNA single strand breaks, activation of PARP1 and development of nervous system.It has been reported that PARP3 is associated with glioma and breast cancers.In this review, PARP3 structure, activation mechanism, biological function and its relationship with diseases will be presented.
