Outbreaks of hand-foot-mouth disease (HFMD) have occurred many times and caused serious health burden in China since 2008.Application of modem information technology to prediction and early response can be helpful for efficient HFMD prevention and control.A seasonal auto-regressive integrated moving average (ARIMA) model for time series analysis was designed in this study.Eighty-four-month (from January 2009 to December 2015) retrospective data obtained from the Chinese Information System for Disease Prevention and Control were subjected to ARIMA modeling.The coefficient of determination (R2),normalized Bayesian Information Criterion (BIC) and Q-test P value were used to evaluate the goodness-of-fit of constructed models.Subsequently,the best-fitted ARIMA model was applied to predict the expected incidence of HFMD from January 2016 to December 2016.The best-fitted seasonal ARIMA model was identified as (1,0,1)(0,1,1)12,with the largest coefficient of determination (R2=0.743) and lowest normalized BIC (BIC=3.645) value.The residuals of the model also showed non-significant autocorrelations (PBox-Ljung (Q)=0.299).The predictions by the optimum ARIMA model adequately captured the pattern in the data and exhibited two peaks of activity over the forecast interval,including a major peak during April to June,and again a light peak for September to November.The ARIMA model proposed in this study can forecast HFMD incidence trend effectively,which could provide useful support for future HFMD prevention and control in the study area.Besides,further observations should be added continually into the modeling data set,and parameters of the models should be adjusted accordingly.

OBJECTIVETo evaluate the clinical efficacy of bladder gasification and stasis dispersion combined with antibiotic therapy in the treatment of III A chronic prostatitis.

METHODSWe conducted a randomized controlled clinical study on 120 III A prostatitis patients that all met the diagnostic criteria. We divided the patients into groups A, B and C of equal number to receive oral medication of sparfloxacin, sparfloxacin + tamsulosin, and sparfloxacin + herbal decoction, respectively, all for a course of 4 weeks. We evaluated the primary therapeutic indexes according to the total scores of the patients on traditional Chinese medicine (TCM) syndrome and NIH-CPSI and the secondary therapeutic indexes based on the count of white blood cells (WBC) in the expressed prostatic secretion (EPS).

RESULTSAfter treatment, the total scores on TCM syndrome and NIH-CPSI were significantly reduced in groups B (42.15 +/- 10.29 and 13.25 +/- 6.04) and C (41.26 +/- 11.25 and 12.38 +/- 7.19) than in A (49.43 +/- 11.09 and 17.62 +/- 5.84) ( P < 0.05), and so was the WBC count in EPS in group C (7.76 +/- 15.73) than in groups A (11.45 +/- 10.33) and B (12.28 +/- 13.81) (P < 0.05). The difference between pre- and post-treatment scores on TCM syndrome was more significant in group C (12.65 +/- 11.76) than in B (8.55 +/- 10.15) (P < 0.05).

CONCLUSIONBladder gasification and stasis dispersion combined with antibiotic therapy is effective for the treatment of III A chronic prostatitis, and therefore deserves wide clinical application.

OBJECTIVETo study the resistant related molecules of human leukemia drug resistant K562 cells (K562/HHT) induced by homoharringtonine (HHT).

METHODSGene expression profiles on K562/HHT, K562 and K562/HHT/RU486 (K562/HHT reversed by RU486) cells were detected by DNA microarray. The bone marrow tyrosine kinase gene in chromosome X (BMX) which changed dynamically among the three cells was confirmed by RT-PCR and Western blot. Then, BMX was transfected into K562 and K562/HHT cells, and the changes of daunorubicin (DNR) concentrations in these two cells were observed for BMX overexpression.

RESULTSAs compared with K562, there were changes in 117 gene expressions in K562/HHT, 57 of which were up-regulated and 60 down-regulated. The mdrl gene was significantly up-regulated. When compared with K562/HHT, 50 significantly differently expressed genes were screened out in the K562/HHT/RU486 cells, of which up- and down-regulated genes were 13 and 37 respectively. These genes involved in drug resistance, cell signaling, cell differentiation, cell proliferation, transcription regulator, ion transport and so on. Four genes [NM-001721 (BMX), NM-031459 (SESN2), NM-033642 (FGF13) and AL-049309 (SFRS12)] expressed significantly differently in the two group cells, BMX gene expression was higher in K562/HHT, than in K562, but lower than in K562/HHT/RU486 as confirmed by RT-PCR and Western blot. After the plasmid pCI-neo-BMX was transfected into K562 and K562/HHT cells, DNR concentration was significantly lower (79.28 +/- 4.04, 29.84 +/- 2.67) than those before transfection (158.52 +/- 8.08, 58.58 +/- 6.53).

CONCLUSIONBMX is associated with multi-drug resistance of K562/HHT cell line.

OBJECTIVETo study the maturation effect of CpG2006 and phosphodiester oligonucleotides on leukemia-derived dendritic cells.

METHODSLeukemia cells K562/A02 were induced into dendritic cells by rhGM-CSF and rhIL-4. After 7 days induction, the cell-morphology was observed, the immunophenotype of cells was detected by flow cytometry and the cell function was evaluated by allogeneic mixed lymphocyte reactions, CTL responses and secretion of IL-12 and IL-6. Then a CpG oligonucleotide CpG2006, two synthetic bacterial phosphodiester oligonucleotides A-ODN and T-ODN were added to these leukemia-derived DCs. Three days later, the DCs were re-detected by the above-mentioned methods.

RESULTSAfter induced by CpG2006, A-ODN or T-ODN, the leukemia-derived DCs with typical dendritic morphology were increased. The expressions of CD83, HLA-DR and CD86 were (65.5 +/- 8.4)%, (32.0 +/- 4.3)% and (18.6 +/- 3.2)% respectively in day 7 leukemia-derived DCs, raised to (88.9 +/- 3.6)%, (53.9 +/- 3.2)% and (39.9 +/- 7.3)% respectively after exposing CpG2006 for 3 days; increased to (97.0 +/- 5.3)%, (63.9 +/- 7.3)% and (40.2 +/- 7.4)% respectively after treated by A-ODN; and further increased to (93.26 +/- 4.65)%, (58.3 +/- 5.6)% and (36.2 +/- 6.8)% respectively after treated by T-ODN. These results was markedly different than unaffected cells did. These DCs induced by the above-mentioned three oligonucleotides could upregulate significantly the capacity for stimulating allogeneic T cells. They could also induce CTL to generate specific cytotoxic activity against K562/A02 cells. The secretion of IL-6 and IL-12 was increased remarkably.

CONCLUSIONCpG2006, as well as two phosphodiester oligonucleotides can induce leukemia-derived DCs maturation.

OBJECTIVETo study whether progestogen antagonist mifepristone could reverse multidrug resistance of K562/A02 cells and its mechanisms.

METHODSMTT was used to study the proliferation of K562/A02 cells and sensitivity of K562/A02 cells to ADM after 72 hours treatment with mifepristone. Flow cytometry was used to assay the expression of P-glycoprotein and the mean fluorescent intensity of intracellular daunorubicin. The expressions of apoptosis related proteins (bcl-2, Bax and caspase-3) were assayed by immunohistochemistry and the glucosylceramide synthase mRNA expression by RT-PCR before and after mifepristone treatment.

RESULTSMTT assay revealed that 2.5, 5.0 and 10 micromol/L mifepristone did not affect the proliferation of K562/A02 cells, but enhanced the sensitivity of K562/A02 cells to ADM, by 1. 68-, 4.17- and 10.71- fold increase, respectively. Expression of P-gp in K562/A02 cells was (49.03 +/- 5.32)%, and was decreased to (28.60 +/- 2.13)% (P < 0.01) after 10 micromol/L mifepristone treatment for 72 hours. and intracellular DNR accumulation in K562/A02 was (61.07 +/- 8.61)%, and was increased to (92.72 +/- 3.48)% (P < 0.01). After 10 micromol/L mifepristone treatment, the expression of bcl-2 protein was decreased from (56 +/- 9)% to (37 +/- 6)% (P < 0.05), Bax and caspase-3 proteins was increased from (40 +/- 5)% to (87 +/- 10)% (P < 0.01), and from (36 +/- 7)% to (89 +/- 6)% (P < 0.01) respectively. RT-PCR analysis revealed that expression of glucosylceramide synthase mRNA was higher in K562/A02 than in K562 cells, whereas 10 micromol/L mifepristone significantly down-regulated its expression in K562/A02 cells.

CONCLUSIONMifepristone at 10 micromol/L could dose-dependently reverse the multidrug resistance of K562/A02 cells. The possible mechanisms are related with decreasing the expression of P-gp, regulating the expression of apoptosis related proteins and decreasing the expression of glucosylceramide synthase.

Within two weeks after treatment, the rebleeding rate was 3.3% (6/180). Within three months after treatment, the rebleeding rate was 7.2% (13/180). No serious complications occurred. The incidence of overall complication was 37.8% (68/180). Conclusion Endoscopic selective varies devascularization has good efficacy and safety, and is worth promoting.

OBJECTIVE To explore the anti-atherosclerotic effect of the extract of traditional Chinese medicine formula Dan-yi-lian(DYL)and the related mechanism.METHODS Atherosclerosis(AS)mod-el was established in ApoE(-/-)mice with a western diet. The mice were orally administered with differ-ent doses of DYL or vehicle daily for 28 d.The anti-atherosclerotic effect was evaluated by measuring the aortic atherosclerotic lesion area and media thickness with ultrasound imaging and histological sec-tions staining method. The effect on blood lipid was investigated by determining TC, TG, LDL, HDL, Apo-A1, Apo-B, etc. The anti-oxidative activity as assessed by determining the level of SOD, CAT, GSH,GSH-Px and MDA.Western blot analysis was used to determine the effect on ICAM-1,VCAM-1, MMP-2 and TNF-α. RESULTS In Dan-yi-lian administered ApoE(-/-)mice,the plaque area and media thickness were significantly reduced. Meanwhile, serum TC, TG, LDL and Apo-B were decreased, in contrast to the increased level of HDL and Apo-A1.On the other hand,SOD,CAT,GSH and GSH-Px were increased, while MDA was reduced in liver homogenate. In addition, the expression of ICAM-1, VCAM-1,MMP-2 and TNF-α was obviously inhibited by Dan-yi-lian.CONCLUSION Dan-yi-lian exhibit-ed potent anti-athero-sclerotic efficacy,in which the lipid-regulating,anti-oxidative and anti-inflammato-ry mechanism might be involved.

OBJECTIVETo study the clinical effect of Chinese drugs administered by both oral intake and retention enema on inflammatory bowel diseases (IBD).

METHODSAdopting a randomized controlled design, 78 patients were assigned to three groups: 26 patients in group A treated with Chinese drugs given by both oral intake and retention enema, 27 in group B with Chinese drugs given by retention enema only, and 25 in group C with given Western medicine. The changes before and after a 30-day treatment of the patients' symptoms (including diarrhea, abdominal pain, mucous or pus-bloody stool), colonoscopic examination scores and histopathology of the colonic membrane were observed.

RESULTSGroup A showed the best outcomes in all the aspects of clinical comprehensive effectiveness. Improvements in the main symptoms, colonoscopic scores and histopathology of the colonic membrane were significantly different from those in groups B and C, respectively (P<0.05). Meanwhile comparisons between groups B and C showed insignificant differences (P>0.05); group B was better in ameliorating tenesmus (P<0.05).

CONCLUSIONThrough the use of Chinese drugs administered by both oral intake and retention enema to treat IBD, which combined external-internal therapies for both overall regulation and local management, it was confirmed that the Chinese medicine could embody the therapeutic principle of attending to both disease-diagnosis and syndrome-differentiation.
