The theoretical system for medical knowledge transfer was studied by analyzing its main research researchers,bodies and contents presenting in different databases-covered papers on medical knowledge transfer from 2005 to 2015,which showed that the main researches on medical knowledge transfer are focused on individuals,teams,organizations and leagues,the main research bodies are doctors,nurses,medical and non-medical staff,patients and their mangers and educators,and the main research contents are the influencing factors and implementation mechanisms for medical knowledge transfer.Although foreign and domestic researches on medical knowledge transfer showed certain differences with some limitations,they are of great importance for perfecting its theoretical system and practical implementation.

OBJECTIVE To reduce the missing report rate of nosocomial infection(NI) by establishing relevant surveillance protocol,improve the early warming system of NI,and therefore prevent the outbreak and prevalence of NI.METHODS Based on Nosocomial Infection Diagnosis Standard published by Chinese Ministry of Health in 2001,116 213 patient data from Jan 2000 to Dec 2006 had been reviewed;factors associated with NI missing report rate had been reevaluated;measures to reduce the rate had been made;and the feedback information of NI control had been collected.Meanwhile,according to high risk factors provided by the hospital information system,the prospective investigations had been made.Surveillance protocol had been established as above.RESULTS By the implementation of the protocol,the missing report rate of NI had been under control,lower than the standard rate of 20% for tertiary hospitals.In 2005,the protocol was reinforced and the NI missing report rate had been reduced to 7.4% by 2006.CONCLUSIONS The real-time monitoring of NI cases is an effective way in reducing missing report rate of NI.

Objective To investigate the clinical features and the efficient therapy of acute promyelocytic leukemia(APL)with high initial white blood cell(WBC)count.Methods The clinical features of 66 newly diagnosed APL patients with high initial WBC and 152 patients without high initial WBC from the First Affiliated Hospital of Soochow University between October 1993 and August 2006 were retrospectively analyzed.Additionally,66 patients with high WBC were divided into different groups according to the different induction therapy and the therapeutic effects were compared.Results The early death rate and the incidence of disseminated intravascular coagulation(DIC)and retinoic acid syndrome(RAS)were 30.3%,57.6% and 31.8% respectively for the group with high initial WBC,which were higher than the indexes of 7.2%,38.1% and 21.05% respectively for the group without high initial WBC(P

Objective To optimize the medium for rhizomatous induction of Belamcanda chinensis in vitro. Methods By plant tissue culture technology, the effects of various carbon source, NAA, and active carbon at different concentration on the rhizomatous formation of B. chinensis in vitro were studied. Results MS+6-BA 2.0 mg/L+NAA 0.5 mg/L+6% white sugar was the optimal medium for the rhiz-omatous formation of B. chinensis in vitro. Active carbon should not be added to the medium. The germination rate of rhizomatous in vitro was 61.03% on the MS + BA 2.0 mg/L+3% white sugar. Conclusion Sugar concentration is the main factor of the influence on the rhizomatous formation of B. chinensis in vitro.

Objective To explore the minimal residual disease (MRD) and cellular chimerism in patients with hematopoietic malignancies after allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods From May 2001 to June 2005,83 patients received allo-HSCT,including 55 males and 28 females. Of them 49 patients received sibling HLA-matched bone marrow transplantation (BMT),3 HLA-matched peripheral blood stem cell transplantation,8 un-related BMT,9 nonmyeloablative stem cell transplantation (NST) and 14 related haploidentical transplantation. Among them,49 patients were diagnosed as having CML,16 having AML,16 having ALL,one having multiple myeloma and one having malignant lymphoma. Chimerism and MRD were monitored by fluorescence in situ hybridization (FISH) using X and Y specific centromeric probes or gene probes for BCR/ABL,MLL and AML1/ETO. 1000 cells were analyzed for each sample.Results Among 19 patients receiving sex-matched transplant,the former chromosome rearrangements were not found in 16 patients after transplantation,MRD was detected in 10 % of cells in one patient and 1 % of cells having MRD in 4th month after the reduction of immunotherapy,and the patients were still in remission one year after transplantation. Two patients were found having the former chromosomal rearrangement 1 and 4 months after transplantation,respectively,who did not achieve remission after chemotherapy. Over 99 % donor chimerisms were found in 50 patients on day 25,donor cells were at a low level ( 96.2 % ~ 98.7 % ) in 7 patients on day 25,and increased over 99 % later. They were in remission without relapse. The donor chimerisms were decreased gradually in other 7 patients,of them 3 patients with the host cells above 10 % showed hematologic relapse. Four patients with the host cells between 2 %~5 % had different outcomes: 2 patients died of severe GVHD after the reduction of cyclosporine A,one patient got a donor chimerism over 99 % after reduction of immunotherapy,and one patient was still in complete remission.Conclusions FISH could play a pivotal role in the detection of MRD and chimerism. It is helpful to the evaluation of graft and relapse and to the guide of intervention of early immunotherapy.

Objective To investigate activation of the phosphatidylinositol 3-kinase(PI3 K)/protein kinase B(Akt)pathway in the endometrium of women with polycystic ovary syndrome(PCOS)and its role in endometrium hyperplasia and carcinogenesis,and the factors affecting the activation of the PI3K/Akt pathway.Methods From Jan 2007 to Jun 2008,52 patients with PCOS who underwent dilatation and curettage were selected as experimental group matched with 32 non-PCOS patients as control group.Serous hormonal parameters,fasting blood glucose and insulin,body mass index(BMI),and endometrium pathology were measured and evaluated in all patients.The PCOS patients were divided into insulin resistance and non-insulin resistance group according to homeostasis model assessment-insulin resistance index (HOMA-IR).Meanwhile,the PCOS patients were grouped as normal,endometrial hyperplasia and carcinoma depending on outcome of pathology.The expression of Akt and phosphorylated Akt(p-Akt)were determined by western blot.Results(1)The expression of p-Akt was significantly higher in PCOS group [(46±18)％]than that in control[(33 ±9)％,P ＜0.01)].(2)The expression of p-Akt was significantly higher in group of endometrial hyperplasia and carcinoma[(56 ± 19)％]when compared with those in normal endometria group[(31 ± 12)％,P ＜ 0.05]; the expression of p-Akt was significantly higher in group of insulin resistance[(50 ± 19)％]compared with that in non-insulin resistance group [(34 ± 10)％,P ＜0.01].(3)There was a positive correlation between the expression level of p-Akt in endometrium with PCOS and HOMA-IR and BMI respectively(r =0.400,0.326,both P ＜ 0.05).Conclusions The PI3K/Akt pathway was over activated in endometrium with PCOS which may be associated with the formation of endometrial hyperplasia and carcinoma in PCOS patients.Insulin resistance and obesity may be high risk factors for over-activation of the PI3K/Akt pathway in endometrium with PCOS.

Objective To explore the clinicalpathological characteristics of Lynch syndrome associated ovarian cancer.Methods Totally 260 cases ovarian cancer patients were admitted to Tianjin Medical University General Hospital during Jan.2004 and Jan.2011,among which 10 patients( LS group) belonged to Lynch syndrome associated ovarian cancer according to Amsterdam Ⅱ criteria.One hundred ovarian cancer patients without any family cancer history were enrolled randomizely as control group (sporadic group).Results Lynch syndrome associated ovarian cancer accounted for 3.8％ ( 10/260),the incidence rate of ovarian cancer for female family members of Lynch syndrome was 8.7％ ( 10/115 ).Mean age at time of diagnosis in LS group was (46 ±7) years,significantly earlier than that in sporadic group [ (56 ±11 ) years,P ＜ 0.05 ].There was no statistical difference between two groups in histological type or International Federation of Gynecology and Obstetrics ( FIGO ) stage ( P ＞ 0.05 ).Most of the tissue differentiation in LS group were well or moderate differentiated,there was statistical difference between the two groups(9/10 vs.55％,P ＜0.05).The 3-year and 5-year survival rate in LS group were 87.5％ and 52.5％respectively,compared with 55.4％and 22.7％ in sporadic group(all P＜0.05).Conclusion Compared with sporadic ovarian cancer,Lynch syndrome associated ovarian cancer is more likely present as the clinicalpathological characteristics of early age of onset,serous adenocarcinoma,lower grade and better prognosis.

Objective:To investigate the site and characteristic ofp53 gene mutations in familial or early-onset breast cancer patients in part population of southern China.Methods:A total of 150 patients with familial and early-onset breast cancer in parts population of southern China were enrolled.Genomic DNA was isolated from each peripheral blood sample,and the entire coding sequence and exon and intron splicing region of p53 gene were amplificated by PCR in the 150 patients.The mutation analysis were detected by denaturing high performance liquid chromatography (DHPLC) and confirmed by DNA sequence analysis.Results:In the 150 patients with familial and early-onset breast cancer,6 mutations including one novel pathogenic mutation 869_888 ins20 (insert mutation) and 5 previously reported pathogenic mutations (deletion mutation 643_660de118 and 4 missense mutation 91G＞A,215C＞G,537T＞G,743G＞A) were identified in p53 gene encoding region in 9 patients of breast cancer.Moreover,one same sense mutation 141G＞A in exon 4,one 16 bases deletion in intron 3,and 9 single nucleotide polymorphisms in p53 gene introns were also identified.The total mutation frequency ofp53 gene in 150 patients with familial breast cancer and early-onset breast cancer from part population of southern China was 6.00％,and the mutation frequency of familial breast cancer and early-onset breast cancer was 6.81％ and 6.25％,respectively.Conclusion:The total mutation frequency ofp53 gene in 150 patients with familial breast cancer and early-onset breast cancer from partpopulation of southern China is higher than the frequency previously reported.The pathogenicity of the novel mutations (insert mutation) 869_888ins20 will be confirmed by function analysis in the future study.The deletion mutation 643_660de118 enriches the p53 gene mutation database among Chinese population,which is probably the specific mutation of breast cancer in Chinese population.
