Cytokine induced killer (CIK)cells are immune effector cells generated from mononuclear cells induced by many cytokines.CIK cells have several advantages, such as rapid proliferation, broad spectrum killing activity, high tumoricidal activity and non-major histocompatibility complex restriction.Recently, cord blood derived CIK cells have attracted extensive concerns because of its faster proliferation, higher tumoricidal activity and lower incidence of GVHD compared with adult peripheral blood derived CIK cells. This paper will review the biological characteristics, clinical application and research advances of cord blood derived CIK cells.

Objective To investigate the clinical pathway in the health education for prevention of postpartum urinary retention and effect evaluation. Methods 150 cases who completed delivery in our hospital were set as the observation group, they received health education of clinical pathways. 150 pregnant women who completed delivery in our hospital in the past were named as the control group, they were given traditional health education. The incidence rate of urinary retention was compared between the two groups. Results 7 cases, accounting for 4.67% of urinary retention occurred in the observation group, 24 patients, accounted for 16.00% of urinary retention occurred in the control group, the incidence of urinary retention in the experimental group was significantly lower than the control group. Conclusions Application of clinical pathway in the health education for prevention of postpartum urinary retention has good clinical value, can largely reduce the incidence of urinary retention.

Objective To effectively manage the archives of medical equipment and realize the sharing of archives information resources.Methods Multi-way management mode integrating internet management platform and intranet was involved in classification management according to the requirements of medical equipment and consumables archives management.Results Distribution company was involved in hospital management as the user,and the workload of the equipment department was relieved effectively.The staff could inquire and input information by logging in the website,and precision and dynamic management of medical equipment electronic archives was realized.Conclusion Network-based medical equipment archives management contributes to the collection and application of the archives.

Objective:To investigate the clinical value of rapid supraclavicular subclavian catheterization during cardiopulmonary resuscitation. Methods:218 patients with cardiac arrest were randomly divided into central and peripheral intravenous groups for drug administration. We compared the effect of two pathways for drug administration during CPR. Results:There were no significant differi-ence in time of catheterization and success rate of catheterizaiton between the two groups. The RSC time in group C was shorter and early success rate was significantly higher than that of group P. Conclusion : Supraclavicular approach to subclavian catheterization for drug administration increased the success rate of CPR at an early stage and proves beneficial to cerebral resuscitation. It will provide the best pathway for drug administration during CPR.

Objective:To investigate the expression of Trophinin gene in the mouse endometrium during the period of blastocyst implantation.Methods:By reverse transcription-polymerase chain reaction(RT-PCR),Trophinin gene in the mouse endometrium of 1～6 day normal pregnancy was detected.Results:The Trophinin mRNA was not detected in endometrium of nonpregnant and 1～2 day pregnant mouse.But in 3～5 day normal pregnancy it was strongly expressed.The Trophinin gene was scarcely detected in the endometrium of the 6 day pregnancy.Conclusion:Expression time of Trophinin mRNA in mouse endometrium coincides with blastocyst implantation.This suggests Trophinin participate in the adhesion of blastocyst and endometrium.

Objective:To study the analgesic effect of rofecoxib on patients with advanced carcinoma.Methods:In a randomized clinical trial,108 pathologically diagnosed cancer patients were treated with rofecoxib(dose 25～50mg/d) and the pain relief was observed among all the patients.Results:Rofecoxib was effective in control of cancer related pain in an oral dose of 25～50mg/day with a total effective rate of 84.26%.The main adverse reactions such as drowsiness,dizziness,nausea,vomiting,discomfort in stomach and constipation were slight.Conclusion:Rofecoxib is effective for relieving cancer related pain with sustained duration and slight in adverse reaction and convenient for administration.

Objective; To study the efficacy, side effect and economic value of morphine controlled - release tablets plus diclofenac sodium and antidepressive drugs in the treatment of pain caused by metastatic bone carcinoma. Methods: 83 patients with pain of meta-static bone carcinoma were randomly divided into two groups. Group I was treated only with morphine controlled - release tablets, Group II with morphine controlled - release tablets, diclofenac sodium and amitriptyline. The dosage of morphine controlled - release tablets, the adverse reaction and the medical cost were observed. Results: The dosage of morphine controlled - release tablets and the medical cost in Group II were obviously lower than those in Group I. The side effects were not significantly different between the two groups. Conclusions: Morphine controlled - release tablets plus diclofenac sodium and antidepressive drugs can treat the pain of metastatic bone carcinoma effectively, relieve the economic burden of the patient while not to increase the side effects.

Objective To compare influence of several biotic elicitors(yeast extract,(oligogalactu-)ronides,and fungal elicitor) and abiotic elicitors(Ag~+,Co~(2+),and ?-amino isobutyric acid) on tanshinone production in the hairy root culture of Salvia miltiorrhiza.Methods The contents of three tanshinones were(analyzed) by high performance liquid chromatography.Results Biotic elicitors increased effectively the yield of tanshinones and there were difference among different elicitors' effects.The highest content of tanshinones was achieved by fungal elicitor at 100 ?g/mL,which was(0.42 mg/g),4.7-fold of the control.The elicitation effects of abiotic elicitors were relatively lower than those of biotic elicitors,with Co~(2+) at 50 ?mol/L giving the highest content of tanshinone(1.75 mg/g,4.1-fold of the control) among abiotic elicitors.Biotic and abiotic elicitors showed the selectivity of elicitation.All biotic elicitors notably increased the crypotanshinone content and all abiotic elicitors selectively enhanced the tanshinone I content.And in most cases,the elicitors added did not cause any obviously inhibitory effect on the hairy root growth. Conclusion Adding different biotic and abiotic elicitors may selectively promote tanshinone accumulation and not affect the hairy root growth in the hairy root cultures of S.miltiorrhiza.

Objective: To establish an in vitro screening system for testing effects of MAD2 gene of embryonic cell genome.Methods: In order to construct the plasmid expressing MAD2-GFP fusion plasmid,the target gene fragment was obtained by RT-PCR amplification and inserted into pEGFP-N1 reporter vector.The structure of constructed plasmid was confirmed by electrophoresis analysis and DNA sequencing.The function of construct was confirmed by lipofectamine-mediated transient expression in HepG2 cells.Results: DNA sequencing showed that the inserted fragment of the constructed plasmid was the same as the template MAD2 genome.The HepG2 cells transfected with the constructed plasmid could express reporter gene of gfp.Conclusions: the plasmid expressing gfp gene controlled by MAD2 gene is successfully constructed and an in vitro testing system for evaluating founction of MAD2 gene in separation of cell is established.
