Fluid therapy plays an important role in maintaining the stability of vital signs and the good perfusion of tissues.Therefore,it is the basis for treatment of diseases.The purpose of fluid therapy is to keep the patient's effective circulating volume,increase cardiac output,and ensure adequate tissue perfusion,which may facilitate the transport of oxygen and nutrients.Perioperative fluid therapy has gone through the progress from choosing the type of liquid to reforming the mode of fluid treatment.Since the concepts of fast track surgery and precision medicine appeared,the anesthesiologists and surgeons have pay more attention to the goal-directed fluid therapy(GDFT).GDFT aims to maintain organ perfusion and oxygen transport of tissues by regulating the amount of fluid on basis of a physiological index.As a new fluid therapy,GDFT contributes to maintaining oxygen delivery and reducing both morbidity and mortality.This article reviews the progress and challenges for GDFT.

For pharmaceutical industries, clinical data is one of the most valuable deliverables. It is also the basis of analysis, submission, approval, labeling and marketing of a drug product. To ensure the integrity and reliability of clinical data, a scientific standardized quality control (QC) has to be established at each step of a clinical trial. Data validation is conducted to ensure the reasonability and compliance of clinical data by checking data quality before the data is statistically analyzed. This paper focuses on purpose of data validation, creation of data validation plan, rationale of data validation, types of data validation and performance of user acceptance testing on clinical database.

Objective Perioperative fluid therapy has always been the most basic and important measure to maintain the stability of patients'cyclic system.Colloid and crystalloid,as common perioperative fluid,play different roles in clinical application due to the different molecular sizes.In the recent years,besides their contribution to maintain the stability of cyclic system,scientists have begun to pay attention to the effect on coagulation,especially their comparison.This paper mainly discusses the study status of the influence on coagulation produced by different liquids.

Objective To explore the expression and significance of phosphatidylinositol-3 kinase (PI3K)in ovarian cancer,and the effect of combined PI3K inhibitor(LY294002)therapy with cisplatin on epithelial ovarian carcinoma,and to explore if there is a synergistic effect between the two therapies. Methods The expression levels of PI3K p85 subunit proteins and mRNA were evaluated by western blot and RT-PCR in normal ovarian tissue(G1),ovarian benign tumor tissue(G2),ovarian borderline tumor tissue(G3)and ovarian cancer tissue(G4),and the relevant clinical pathological parameters were analyzed.SKOV3 ceils were isolated and cultured by enzymolysis method.SKOV3 cells were treated with culture medium only,LY294002(1,10,30,50,100 ?mol/L),cisplatin(0.33,1.25,2.5,5, 10 ?mol/L),LY294002(50 ?mol/L)+cisplatin(10 ?mol/L)for 2 days,respectively.The effect of LY294002 and cisplatin on the growth of SKOV3 cells was measured by methyl thiazolyl tetrazolium assay. Results There was no positive expression of PI3K p85 subunit proteins in G1 and G2,while the expression was 2/6 in G3,and 85%(33/39)in G4.PI3K p85 subunit mRNA expression levels were 0.178?0.102 in G1,0.643?0.112 in G2,0.847?0.058 in G3,1.689?0.423 in G4;there was a significant difference between G1,G2,G3 and G4(P0.05).Significant differences were noted between protein expression levels in G4(Ⅲ,Ⅳ)and G4(Ⅰ,Ⅱ;P

Diabetes,characterized by chronic increase of blood glucose,is a group of metabolic diseases.It is usually treated by oral administration with antidiabetic drug and insulin with western medicine.Diabetes is called consumptive thirst in TCM.Professor NAN Zheng thought the pathogenesis of consumptive was yin defi ciency and dryness-heat at the early stage,and at the protracted stage it was usually characterized by qi defi ciency,blood stasis,pathogen intruding into collateral and poison damaging zang and fu.He established a series of treatment plan,involving diet,movement,and the Chinese materia medica.Professor NAN opposed to abusing insulin and the insulin multi-purpose theory,and proposed the treatment should start from change of bad life style and combine with application of Chinese medicine to regulate yin-yang and qi-blood of fi ve viscera,treat triple diabetes at the same time.So long as syndrome differentiation was accurate,the Chinese materia medica may replace the insulin and prolong the life.In conclusion,this article enumerates 3 typical cases diabetes withdrawal of insulin with TCM by Professor NAN Zheng.

180 min and arterial blood pressure instability are independent determinats for cerebral complication. Conclusion No single risk factor explained the onset of cerebral complication. Rather, a combination of factors, especially longer CPB time, postoperative arterial blood pressure instability produced the highest odds of deficit.

OBJECTIVE To find out the status of and impact factors on bacterial concentration in clean operating room.METHODS Set a questionnaire to the staff in the operating room of 24 tertiary 3A hospitals.RESULTS The 9 basic questions got correct and accordant answers.The answers for the 5 questions which were related to the characteristic of clean operating room had biger errors and difference.CONCLUSIONS The investigatees know about the basic requirements of the detecting method for bacterial concentration,but lack for the exact cognition of special requirements in clean operating room(e.g.State standard).The sticking point of the current problem is the misunderstanding on the 5 key questions.In order to make sure the excellent air condition in the cleaning operating room,the training of correlative specialty is very important.

Objective To establish and stabilize a new HLA-B locus typing strategy, reference strand mediated conformation analysis(RSCA)system and to conform its advantages.Methods Of 27 hematopoitic stem cell transplant patients and 63 potential donors DNA samples were extracted from peripheral blood cells and HLA-B loci were both typed by RSCA and PCR-SSP methods. The (ambi)-(guous) results were identified by using DNA sequencing. Results Among 90 samples, 87/90 ((96.7) %) cases could be designated definitely, but one of them was disagreement with the SSP result which was confirmed by sequencing, and 67/90 ((74.4) %) cases could be typed to allelic level. 1/90 ((1.1) %) case could not be identified by RSCA for its bad PCR results. Only one allele of each 2 samples could be designated and the other could not be identified by RSCA, which were further confirmed by sequencing method, and the results confessed which were known as alleles, but there were no corresponding data in RSCA database. Twenty samples were randomly selected to identify the replication rate of RSCA, and the results demonstrated that the replication rate was 100 %. Among PCR-SSP typing results, about 10 % samples might be typed for 1-3 times to confirm their types. Conclusion RSCA had some advantages such as high resolution, high sensitivity, high accuracy, high replication, finding new alleles, large scale and low cost, and was especially suitable for unrelated donor-recipient (screening).

ObjectiveTo study the effects of angiogenesis on the development of endometrial carcinoma. Methods Hysterectomy specimens were stained immunohistochemically by the marker of factor Ⅷ-related antigen for endothelium vessels in normal controls, patients with endometrial hyperplasia and with endometrial carcinoma. Results The microvascular density(MVD) in tumour increased gradually from normal endometrium to endometrial hyperplasia and to endometrial carcinoma(P<0.01). MVD correlated with the mvometrial invasion, histologic grades and the stages.ConclusionMYD in endometrial hyperplasia increases. MVD can be used as a prognostic factor.
