OBJECTIVE:To evaluate the effects of clinical pharmacists participating in disease management of chronic heart failure(CHF). METHODS:A total of 180 CHF inpatients selected from cardiovascular medicine department of our hospital during Jan. 2013 to Dec. 2014 were divided into control group and pharmacist management group according to random number table,with 90 cases in each group. The control group was given routine treatment. The pharmacist management group additionally received indi-vidualized pharmaceutical care,such as pharmaceutical monitoring,psychological counseling,medication education and 6-month follow-up. The comprehensive self-care ability of the 2 groups were compared on admission and on discharge;re-hospitalization and mortality were compared between 2 groups within 6 months after discharged;the patients’NYHA classification,LVEF,plas-ma level of NT-proBNP and quality of life were compared between 2 groups on admission and 6 months after discharge. RE-SULTS:There was no statistical significance in the cognition of patients to disease,self-care ability,medication compliance score and total comprehensive self-care ability score between 2 groups on admission (P>0.05). Each score and total score of 2 groups were better on discharge than on admission,and the pharmacist management group was better than control group,with statistical significance(P<0.05). Within 6 months after discharge,re-hospitalization rate of pharmacist management group was significantly lower than that of control group,with statistical significance (P<0.05). There was no statistical significance in mortality rate be-tween 2 groups (P>0.05). There was no statistical significance in NYHA classification,LVEF,plasma level of NT-proBNP be-tween 2 groups on admission(P>0.05). 6 months after discharge,the above 3 indexes of pharmacist management group as well as NYHA classification and plasma level of NT-proBNP of control group were improved significantly compared to on admission;NYHA classification,LVEF and plasma level of NT-proBNP of pharmacist management group were better than those of control group at corresponding period,with statistical significance (P<0.05). There was no statistical significance in social limit,mood, symptom score and total score of life quality between 2 groups on admission(P>0.05). 6 months after discharge,each score and total score of 2 groups were all better than on admission,and the pharmacist management group was better than control group, with statistical significance (P<0.05). CONCLUSIONS:The participation of clinical pharmacists in the disease management of CHF can significantly improve comprehensive self-care ability,decrease re-hospitalization rate,ameliorate cardiac function and en-hance the quality of life.

Objective To study the expression and significance of Th17 cells from peripheral blood of patients with rheumatoid arthritis (RA). Methods Intracelluar flow cytomete detection of IL-17/IFN-γ and IL-17/IL-6 was established using anti-CD3/Anti-CD28/IL-23 as stimulators after isolation of untouched human CD4~+T cells from PBMC. There were three groups in the present study: ①healthy controls group; ② RA stable group; ③RA active group. Results The isolation of untouched human CD4~+T cells from PBMC was effective and its purity was over 90%. The percentage of intracelluar IL-17 in CD4~+ T cells from RA patients was increased significantly. Such percentage in active group (1.54±0.41) was higher than that of stable group (0.70±0.21, P<0.01) and both of them were higher than those of healthy controls (0.42±0.12, P<0.01). Under anti-CD3/Anti-CD28/IL-23 stimulation, the percentage of intracelluar IL-17 was also increased significantly(P<0.01). The porcentage of intracellular IFN-γ was similar to that of IL-17, while that of IL-6 was not significantly different. There is an correlation between IL-17 and IFN-γ or IL-6. Conclusion There is an abnormal expression of IL-17 and IFN-γ in human CD4~+T cells in RA patients, which is related to disease activity . Th17 cells may be used as a new marker for the assessment of RA activity.

Objective To study the expression of IL-17, RORγt in CD4+T cells from patients with ankylosing spondylitis (AS). Methods The specimens of venous blood PBMC were collected from 28 patients with AS and 15 healthy subjects. Intracellular flow cytometry detection of IL-17 was established after isolation of human CD4+ T cells from PBMC. The expression level of IL-17, RORγt mRNA in CD4+ T cells was determined from 28 AS patients and 15 healthy controls by real-time fluorescence quantitative RT-PCR using Anti -CD3/Anti -CD28 as stimulators or not. Analysis of variance and Pearson correlation were selected. Results The isolation of human CD4+ T cells from PBMC was effective and its purity reached 90%. The percentage of intracellular IL-17 in CD4+ T cells from AS pati-ents in the AS active group was higher than that of the AS stable group and healthy control group (P<0.01). The expression level of IL-17, RORγt mRNA in CD4+ T cells was significantly higher in patients with AS than in controls. After stimulated with anti-CD3/ anti-CD28 stimulation, the percentage of IL-17, RORγt mRNA was increased significantly (P<0.01). The percentage of IL-17, RORγt mRNA in the 12 h group was higher than that of the 24 h group, while both of them were higher than those without stimulation (P<0.05). Conclusion There is an abnormal expression of IL-17, RORγt in human CD4+ T cells from AS patients. Our results indicate that the abnormal expression of IL-17 might play a role in the development and progression of AS.

The LEAFY (LFY) homologous gene of Dendrobium moniliforme (L.) Sw. was cloned by new primers which were designed based on the conservative region of known sequences of orchid LEAFY gene. Partial LFY homologous gene was cloned by common PCR, then we got the complete LFY homologous gene Den LFY by Tail-PCR. The complete sequence of DenLFY gene was 3 575 bp which contained three exons and two introns. Using BLAST method, comparison analysis among the exon of LFY homologous gene indicted that the DenLFY gene had high identity with orchids LFY homologous, including the related fragment of PhalLFY (84%) in Phalaenopsis hybrid cultivar, LFY homologous gene in Oncidium (90%) and in other orchid (over 80%). Using MP analysis, Dendrobium is found to be the sister to Oncidium and Phalaenopsis. Homologous analysis demonstrated that the C-terminal amino acids were highly conserved. When the exons and introns were separately considered, exons and the sequence of amino acid were good markers for the function research of DenLFY gene. The second intron can be used in authentication research of Dendrobium based on the length polymorphism between Dendrobium moniliforme and Dendrobium officinale.

OBJECTIVETo analyze the clinical features, therapeutic methods and prognosis of primary breast lymphoma (PBL).

METHODSTwenty-one PBL patients treated in Ruijin Hospital from January 2003 to December 2013 were included in this study, with 17 diffuse large cell lymphoma (DLBCL), 1 mucosa-associated lymphoid tumor (MALT), 1 follicular lymphoma (FL), 1 Burkitt lymphoma and 1 subcutaneous peniculitis T-cell lymphoma according to the WHO 2008 classification. Of 21 patients, only one patient with MALT has bulged tumor mass (>7 cm), other patients had tumor mass <5 cm. Six patients had core needle biopsy of tumor, 2 modified radical operation, and others tumor excision for diagnosis. All the patients received chemotherapy. The impacts of surgery, rituximab and prophylaxis with lumbar puncture on the outcomes of patients were analyzed. Survival was estimated using Kaplan-Meier method and compared by log-rank test. All the results were analyzed by SPSS 10.0.

RESULTSAmong 21 PBL patients, 19 achieved complete remission (CR), 1 partial remission (PR) and 1 disease progression (PD). Followed-up till July 2014, with median follow-up of 14 months (6-75 months), only one patient died, with 3-year survival of 92.3%. Compared with chemotherapy alone, the progression-free survival (PFS) of combination therapy (surgery plus chemotherapy) was significant longer (P=0.015), but without statistic differences of CR rate and overall survival (OS) between two groups. Among the 20 patients with CD20-positive tumor cells, 17 received Rituximab. PFS and OS, as well as CR rate of PBL had no difference between the treatment with and without Rituximab. The incidence of central nervous system (CNS) infiltration had no difference between patients with and without CNS prophylaxis through lumber-puncture and intrathecal injection.

CONCLUSIONWith the common subtype of DLBCL, PBL patients had good outcome. Surgery, as a method to obtain tumor samples for diagnosis, could not prolong OS of patients. Therefore, radical operation shouldn't be recommended. PBL was reported to have high risk of CNS events, but prophylaxis with lumber puncture and intrathecal injection couldn't decrease the incidence of CNS infiltration.

OBJECTIVETo investigate the role of TRB3 in the inhibitory effect of fenofibrate against the proliferation of glomerular mesangial cell induced by high glucose.

METHODSRat glomerular mesangial cells (MCs) were cultured in the presence of 5.5 mmol/L glucose (normal control), 25 mmol/L glucose (high glucose group), or high glucose along with 10, 50, or 100 µmol/L fenofibrate. Cell counting kit-8 (CCK-8) assay was used to evaluate cell proliferation, and Hoechst 33258 staining was employed to determine chromatin distribution in the MCs. Flow cytometry was performed to analyze the cell cycle changes in different groups. The expressions of TRB3 and P-AKT in different groups were detected using immunocytochemistry and Western blotting.

RESULTSHigh glucose induced obvious proliferation of the MCs (P<0.001), which was significantly inhibited by fenofibrate in a concentration-dependent manner (P<0.001). The MCs exposed to fenofibrate presented with typical apoptotic morphologies and cell cycle arrest at G1/S phase. Low levels of TRB3 expression was detected in the normal control and high glucose groups, whereas in the 3 fenofibrate groups, TRB3 expression increased and P-AKT expression decreased as fenofibrate concentration increased.

CONCLUSIONFenofibrate can promote TRB3 expression in rat MCs. TRB3 causes cell cycle arrest at G1/S phase by inhibiting AKT phosphorylation to result in suppressed proliferation of the MCs.
