Treatment of all the cases were based on differential diagnosis of zheng. Oral medicines were given to the cases in two groups, the damp - heat type and the type of Yin - deficiency blood - heat together with dampness. Of the 15 cases, 14 were markedly effective, a relapsed case was ineffective, the average days of antipyresis was 5 days, demonstrating that the therapy was rather satisfactory and helpful to their convalescence.

Objective:To explore characteristics of TCM syndrome differentiation of graft versus host disease(GVHD)after transplantation of the hemopoietic stem cell,so as to provide basis of clinical syndrome differentiation for further studying on treatment of this disease.Methods:62 cases of GVHD were grouped according to acute or chronic GVHD,and a total of 85 cases-times were investigated for TCM syndrome differentiation.Results:in 50 cases-times of acute GVHD,damp heat type accounted for 68% and 50% have jaundice due to hepatic injury;blood-heat and Yin-deficiency accounted for 32%,with more patients of more severe condition.In 35 cases times of chronic GVHD,damp heat type accounted for 25.7% with more patients companied with Yin- deficiency,blood stasis and Yin-deficiency rate accounted for 74.3%.Conclusion:Commonly-seen basic TCM syndrome types of GVHD are damp-heat and Yin-deficiency types.Damp-heat type was more common in acute GVHD and blood-heat and Yin- deficiency type was.more frequently found in severe patients;chronic GVHD manifest mainly as Yin-deficiency type and with exacerbation of condition and prolongation of disease course,Yin-deficiency type tends to increase.

Objective To investigate early reduction of the dose of immunosuppressive drug after allogeneic peripheral blood stem cell transplantation(allo-PBSCT)for patients with refractory or relapsed leukemia.Methods Between Janaury 2004 and December 2006,15 patients with relapsed or refractory leukemia in Department of Hematology,the First Affiliated Hospital,Sun Yat-Sen University and Institute of Hematology & Blood Diseases Hospital,CAMS & PUMC,received allo-PBSCT from their relatives,12 from HLA-identical siblings.The preparative regimens included BuCy and TBICy with or without cytarabine.Cyclosporine A(CsA)or tacrolimus was used for graft-versus-host disease(GVHD)prophylaxis,with rapid decreasing starting on day 30 of post transplant if no GVHD appeared in receipts of matched sibling tranplantation.Results(1)Faster engraftment was achieved in all patients.Grade Ⅰ~Ⅱ acute GVHD appeared in 5 patients.Chronic GVHD occured in 7 of 11 evaluable patients.(2)Of 9 patients with an lower CsA or tacrolimus dosage,only 1 developed grade Ⅰ acute GVHD,4 chronic GVHD,2 extramedullary relapse.(3)After a median follow-up of 328 days,8 patients has leukemia-free-survival(LFS),4 relapsed,and only 1 had transplantation-related mortality(TRM)in the first 3 months post-transplant.The estimated LFS at 1 year and 2 years was 51% and 25%,respectively.Conclusion Patients with advanced leukemia might benefit from allo-PBSCT with significant lower treatment failure incidence.Dose reductions of CsA and tacrolimus in early transplant might enhance graft-versus-leukemia effect,and improve long-term LFS.

OBJECTIVE To investigate the distribution and resistance of fungi isolated from hemopathy patients,and to provide the laboratorial data in order to prevent and treat infection caused by fungi more effectively.METHODS Strains were isolated from the upper respiratory tract,lower respiratory tract,genitourinary tract,alimentary tract;and perianal region,perineum,and the soft tissue and skin wounds.Antimicrobial susceptibility of clinical isolates was tested by broth microdilution susceptibility test.RESULTS Candida albicans,Aspergillus,tropicalis,C.krusei,and C.glabrata were the main fungi of total 3104 detected isolates.The resistance rates of C.albicans and C.tropicalis to fluconazole,itraconazole and 5-flucytosine were no more than 1.4%.The MIC50-MIC90 range of C.tropicalis for itraconazole was narrow(0.25-0.5 mg/L),but that was wide for fluconazole(0.25-4.0 mg/L).CONCLUSIONS C.albicans,Aspergillus,C.tropicalis,C.krusei,and C.glabrata are possibly the most common pathogens causing endogenous and exogenous fungi infection.The main infection sites of Aspergillus are the upper respiratory tract and lower respiratory tract,which may be associated possibly with ward's air quality.The MIC50to MIC90 range of C.tropicalis is wider for fluconazole than for itraconazole,which is possibly correlated with overexpression of CtMDR1 in C.tropicalis caused by the widely application of fluconazole in therapy.

A microcapsule is a spherical, with a diameter that can be controlled in the range of 200 -1500 μm and biocompatible semipermeable membrane, which allows the bidirectional diffusion of nutrients,oxygen, secreted therapeutic product, and waste but prevents the penetration of high molecular weight substances from the microcapsule, such as antibodies and immunocytes. In comparison to monolayer culture and multicellular tumor spheroid model, orthotopic injection of microencapsulated tumor cells has uncomparable advantages in cell proliferation, mimicking the in vivo situation, making orthotopic tumor model and distant organ metastases model. Microencapsulated tumor assay has the potential of being widely used for in vitro anticancer drug screening and evaluation of the effects. This article mainly reviews the advantages of microencapsulated tumor assay and its application.

Objective To investigate the effects of cytarabine(Ara-C) on expression of B7 molecules and immunogenicity of acute leukemia (AL) cells. Methods The expression of B7 molecules on fresh AL ceils and on the Ara-C exposed leukemia ceils was detected by FACS cytometer. B7 mRNA in Ara-C treated HL-60 cells were detected by reverse RT-PCR. The stimulation of proliferation of allogeneic PBMC by Ara-C treated HL-60 cells was detected by MTT method. Results B7-2 was weakly expressed in four and positive in three, whereas BT-1 was positive in only one of fourty AL patiens. Ara-C significantly enhanced B7 molecules expression on AL cells. Ara-C could induce higher expression of B7 mRNAs on HL-60 cells.Ara-C treated HL-60 cells could stimulate PBMC proliferation and promote their IFN -γ production.Conclusion Fresh AL cells express low level of B7 molecules. Ara-C enhances the B7 molecules expression on AL cells. The Ara-C treated leukemia cells can significantly stimulate the proliferation of allogeneic PBMC and induce their secretion of IFN-γ.

Objective To analyze the susceptibilities of Escherichia coli isolates collected from blood and the prevalence of ESBLs encoding genes.Methods A total of 121 Escherichia coli isolates collected from blood during 2012 were analyzed for antimicrobial susceptibilities by software of WHONET 5.6,the production of ESBLs was confirmed by confirmatory pheno-typic testing,PCR and DNA sequence were further implemented to analyze the ESBLs-encoding genes.Results 121 E.coli isolates displayed high resistance towards broad spectrum penicillin and 2nd or 3rd generation cephalosporins,levofloxacin and cotrimoxazole,with the resistance rates being more than 40%,susceptibilities to imipenem,piperacillin/tazobactam,ami-kacin were observed,with the resistance rates to be less than 12%,86(88.7%)out of 121 isolates were found to produce ESBLs.Among them,59.5% (72),38.8% (47)and 4.1% (5)were confirmed to carry blaCTX-M,blaTEM and blaSHV genes.Additionally,2(1.7%)isolates carried all the genes detected,30(24.8%)isolates carried both of blaCTX and bla-TEM,1(0.8%)isolate carried both of blaSHV andblaTEM.Conclusion Most of the E.coli isolates from the blood culture in Nanjing Gulou Hospital produce ESBLs,and displayed resistance towards most of the penicillins,cephalosporins and sin-gle amide antimicrobial agents should be chosen according to susceptibility results.

As a component of traditional Chinese medical therapies, the therapeutic effects of acupuncture for some nervous system diseases have been proven by a large number of clinical and experimental studies. But, the electrophysiological techniques of the commonly used EEG and evoked potentials are still not sufficient to reveal the functional mechanism of acupuncture therapy. The recording technique of microelectrode array (MEA), a kind of electrophysiological technique originated from the overseas biological electrical signal monitoring technique, can be used to record multiple electrical signals of the nervous cells in vivo or in vitro, and maintain the accuracy and stability of the recorded information at the same time, which greatly enriches the means of electrophysiological study. This technique has been already applied in the basic study and clinical treatment abroad, but it is very seldom used in the study of acupuncture field. In order to guide the application of MEA in the research field of acupuncture science, a general survey about the application of MEA technique in vivo was done, and the present situation and prospects of the application of the technique in acupuncture science was briefly analyzed.

Objective To explore the therapeutic effects and mechanism of bone marrow mesenchymal stem cells (MSC) transplantation in mice autoimmune hepatitis (AIH).Methods AIH model was established in 44 C57BL/6 mice,which were induced by homologous series liver-specific antigen S-100 and Freund's complete adjuvant.After modeling,six mice were collected for AIH model confirming.The other 38 mice were divided into three groups.Fourteen mice of MSC transplantation group (group A) were treated by MSC tail vein injection,12 mice of dexamethasone (DXM) group (group B) were treated by DXM intraperitoneal injection,and 12 mice of PBS control group (group C) received phosphate buffer saline (PBS) intraperitoneal injection.Eighteen mice of healthy control group (group D) weren't modeled and received no treatment.At the 5th and 9th week,the mice weights and serum alanine aminotransferase (ALT) level were tested,mice liver tissues of each group were estimated by pathological examination and Knodell scoring,and spleen T lymphocytes of mice were isolated for proliferation-inhibition examination.The data were analyzed by rank sum test,ANOVA and t test.Results After treatment,mice weights of both group A and B showed upward trend (F=15.678,P＜0.01; F=3.730,P=0.037).Before and after treatment,there was no significant difference in group C (P＞0.05).At the 5th and 9th week,the ALT level of group A and B gradually decreased,there was statistical significance between the time points (F=20.267,P＜0.01; F=4.277,P=0.034).Before and after treatment,there was no significant difference in ALT level of group C (P＞0.05).At the 5th and 9th week,the degree of mice serum ALT reduction of group A was larger than that of group B,and the difference was statistically significant (t=3.566 and 3.218,both P＜0.05).At the 5th and 9th week,the Kondell scores of group A and B gradually decreased,there was statistical significance between the time points (F=8.070,P=0.003; F=6.547,P=0.009).Before and after treatment,there was no significant difference in Kondell scores of group C (P＞0.05).At the 9th week,there was statistical significance in Kondell scores among group A,group B and group C (F =4.477,P =0.029).The in vitro spleen lymphocytes proliferation-inhibition experiment demonstrated that the supernatant of MSC could significantly inhibit the proliferation of T lymphocytes stimulated by S-100 antigen and concanavalin A,the absorbance values were0.267±0.167 vs.0.217±0.128 and0.165±0.187 vs.0.082±0.051 respectively,the differences were statistically significant (t =7.187 and 4.602,both P＜ 0.01).Conclusion MSC transplantation may play a therapeutic role in mice AIH through inhibiting T lymphocyte proliferation.
