This study is to explore the interventional effects of fluvastatin on anti-beta2GPI/beta2GPI-induced activation in THP-1 mononuclear cells. In vitro, human mononuclear cells THP-1 were treated with fluvastatin, LPS and anti-beta2GPI/beta2GPI, then the TF expression on THP-1 cells was detected by real-time quantitative PCR (RT-qPCR) or TF activity was detected by kit. TNF-alpha mRNA and its protein expression were investigated by RT-PCR and ELISA kit. The expression of phospho-NF-kappaB p65 and inhibitory protein of NF-kappaB (IkappaB-alpha) were measured by Western blotting. The results suggested that the expression of TF and TNF-alpha on THP-1 cells was significantly up-regulated with treatment of anti-beta2GPI/beta2GPI complex (100 mg x L(-1)), compared with that of untreated cells (P < 0.05). Fluvastatin (50 mg x L(-1)) could decrease TF (mRNA and activity) expression and the level of TNF-alpha (mRNA and protein) in THP-1 cells with anti-beta2GPI/beta2GPI complex. The expression of TF and TNF-alpha was shown in a concentration-dependent manner. Moreover, anti-beta2GPI/beta2GPI complex could downregulate IkappaB-alpha levels and increase the levels of phospho-NF-kappaB p65. And these effects of anti-beta2GPI/beta2GPI complex could be blocked by fluvastatin. In conclusion, fluvastatin may interfere the expression and regulation of NF-kappaB signal transduction pathway, thereby inhibit the effects of anti-beta2GPI/beta2GPI on activation of THP-1 cells, by decreasing the expression of TF and TNF-alpha.

AIM:To study whether inhibition of forkhead box protein M1(FoxM1) sensitizes leukemia K562 cells to homoharringtonine ( HHT ) .METHODS: K562 cells were incubated with HHT at different concentrations ( 0μmol/L, 0.015 μmol/L, 0.030μmol/L and 0.045μmol/L) for different time (0 h, 24 h, 48 h and 72 h).The mRNA and protein levels of FoxM1 were detected by real-time PCR and Western blot.FoxM1 siRNA was transfected into K562 cells with 0.015μmol/L HHT after 6 h.After 72 h incubation, the cell proliferation was detected by cell counting and soft agar assay, and the proportion of apoptotic K562 cells was determined by flow cytometry.The expression of c-Myc and Sp1 were detected by real-time PCR and Western blot.RESULTS:FoxM1 expression was reduced time-dependently and dose-dependently, suggesting that HHT mediated the downregulation of FoxM1 in K562 cells.In K562 cells, treatment with FoxM1 siRNA and HHT inhibited the cell proliferation and promoted the apoptosis significantly.Therefore, inhibition of FoxM1 sensitized leukemia K562 cells to HHT.The expression of c-Myc and Sp1 was positively regulated by FoxM1. CONCLUSION:HHT inhibits Forkhead box protein M1 expression in K562 cells.Inhibition of FoxM1 sensitizes K562 cells to HHT.

Objective To investigate the clinical efficacy of prucalopride in the treatment of severe chronic constipation.Methods The clinical data of 60 patients with severe chronic constipation [slow transit constipation (STC), functional defecation disorder (FDD) and constipation-predominant irritable bowel syndrome (IBS-C)] who were admitted to the Third Affiliated Hospital of Nanjing University of Chinese Medicine from February to August 2014 were prospectively analyzed.A prospective, clinical observational study was performed.Treatment plans included that patients withdrew the initial treatments of laxative and exema and took orally 2 mg prucalopride once daily for 2 weeks, and continued to be treated by oral prucalopride if frequency of the spontaneous complete bowel movement (SCBM) per week was satisfactory (or improvement of symptoms was more than 50％) till 4 weeks, and then were followed up after stopping prucalopride.If improvement of symptoms was less than 50％ after 2-week treatment, other treatment plans were performed according to symptoms of patients from week 3 to week 6 : (1) for patients with STC, prucalopride + two chain bacillus subtilis probiotic capsules were administered orally if patients were satisfied with frequency of SCBM per week and without improvement of abdominal distension;prucalopride + Chinese herb decoction were administered orally if patients had improvement of frequency of SCBM per week with abdominal distension or poor stool output;oral prucalopride + acupuncture were administered if patients were unsatisfied with frequency of SCBM per week or less bowel movements and without improvement of abdominal distension or poor stool output.(2) For patients with FDD, oral prucalopride + acupuncture + biofeed-back therapy were administered.(3) For patients with IBS-C, prucalopride + two chain bacillus subtilis probiotic capsules were administered orally if patients had abdominal distension;prucalopride Chinese herb decoction were administered orally if patients had improvement of frequency of SCBM per week and no improvement of abdominal distension or poor stool output.All patients used a diary for recording the frequency of SCBM per week, stool consistence, exertion in defecation and adverse reactions, which was submitted to doctors for inputting data at the return visit weekly.Results There was good overall medicine compliance in patients.Of 60 patients, 43 patients completed treatments (21 with STC, 11 with FDD and 11 with IBS-C).After 2-week treatment, there were 19 patients with satisfied therapeutic effects, 14 with improvement of constipation and 10 with poor therapeutic effects.After 4-week treatment, constipation in 17 patients was cured, constipation in 18 patients was improved,and constipation in 8 patients was not improved.Nineteen of 60 patients were complicated with adverse reactions within 1 week of the medication, including 6 patients dropping out of the trial due to medication withdrawal and others with improvement by symptomatic treatment or spontaneous remission.Conclusions Prucalopride is effective for the treatment of severe chronic constipation with a good toleration, and it can improve the overall satisfaction of patients combined with Chinese herb decoction and acupuncture.

Objective:To analyze the structure modes of general practice teams in community health care cen-ters in order to provide empirical evidence for the transformation of the community health service mode. Method:Pur-posive sampling was adopted. Twelve community health service centers in Beijing, Shanghai, Zhengzhou and Cheng-du, where the transformation of the community health service mode was piloted earlier and representative, were se-lected as the field survey sites. The qualitative method was used to collect the data accompanied by the quantitative method. Results:The structure models of general practice teams could be divided into four types:1) general practi-tioner+nurse+nurse assistant+pharmacist, 2) physician (general practitioner, herbalist physician) +nurse+com-munity volunteers, 3 ) physician ( general practitioner/herbalist physician ) +nurse +assistant +community volun-teers, and 4) general practitioner+nurse+assisting team (professionals of public health and maternal care, etc) +supportive team ( pharmacists, health technician, etc) . Conclusion:The paper verified the common sense conclusion that general practitioners should play an essential role in general practice teamwork. The four general practice team models analyzed above positively contributed to the improvement of efficiency and quality, the relationship between health professionals and patients, the promotion of community participation, and the combination between preventive care and clinical care.

Hepatitis B virus (HBV) is a major cause of chronic liver disease, and frequently results in hepatitis, cirrhosis, and ultimately hepatocellular carcinoma. HBV polymerase (Pol) is an essential viral protein that is important for HBV replication and might be involved in the development of hepatocellular carcinoma. Protein-protein interactions appears to be crucial for its role. The aim of this study was to screen and identify the proteins that interact with Pol using a co-immunoprecipitation-based LC-MS/MS identification technique. The HBV Pol gene was amplified by polymerase chain reaction (PCR) and cloned into pCDNA3.1(+). The recombinant plasmid pCDNA3. 1(+)-Pol-flag was transfected into HeLa cells. Liquid chromatography and tandem mass spectrometry (LC-MS/MS) identified 45 proteins that co-immunoprecipitated with flag-tagged HBV Pol. Eleven of these have previously been reported as proteins that interact with HBV Pol. A proof-of-concept-based Ingenuity Pathway Analysis (IPA, www.ingenuity.com) was used to characterize the functions and pathways of these 45 identified proteins and HBV Pol. Among these proteins, four proteins may play a role in three major molecular cellular networks, and are therefore worthy of further investigation.
