The tobacco epidemic is a problem with serious consequence for public health in the whole world. Reducing the tobacco harm and protecting public health have become a crucial topic for ethics. This paper, firstly, presents some facts related to the tobacco epidemic. Based on these facts, then, it analyzes the issue from ethical perspectives. And finally, it discusses the moral responsibilities for reducing the tobacco epidemic.

OBJECTIVETo observe the clinical effect of Shugan Yiyang Capsules combined with sertraline in the treatment of premature ejaculation (PE).

METHODSWe randomly assigned 192 PE patients to receive sertraline hydrochloride 50 mg qd (control group, n = 96) or sertraline hydrochloride 50 mg qd plus Shugan Yiyang Capsules at the dose of 4 capsules tid ( combination therapy group, n = 96) , both for 6 weeks. We compared the intravaginal ejaculatory latency time (IELT) and Chinese Index of Premature Ejaculation ( CIPE) scores between the two groups of patients before and after medication and at 6 weeks after drug withdrawal.

RESULTSCompared with the baseline, the IELT was significantly increased after 6 weeks of medication in the combination therapy group ([1.41 ± 0.53] vs [6.69 ± 3.56] min, P < 0.05) and the control group ([1.43 ± 0.48] vs [5.37 ± 2.91] min, P < 0.05), and so was the CIPE score in the former (9. 80 ± 2.06 vs 21.62 ± 4.76, P < 0.05) and the latter group ([9.41 ± 1.97] vs [20.85 ± 4.83] , P < 0.05). In comparison with the pre-medication indexes, the IELT ([3.77 ± 1.63] min) and CIPE score (16.92 ± 3.37) of the combined therapy group were remarkably improved at 6 weeks after drug withdrawal (P < 0.05), but not those of the control ([1.19 ± 1.34] min and 10.59 ± 2.38, P > 0.05).

CONCLUSIONShugan Yiyang Capsules combined with sertraline have a definite and lasting effect on premature ejaculation.

Objective To investigate the effect of different stimulating culture conditions and detecting methods on the frequency of Th17 cells and to set up and optimize the experimental method for detecting the frequencies of human Th 17 cells in peripheral blood by flow cytometry (FCM ) .Methods The peripheral blood in the healthy people was performed the stimulating culture by phorbol myristate acetate (PMA) at different final concentrations(50 ,100 ,150 ,200 ,250 ,300 ng/mL) and ionomycin 1 μg/mL .The frequencies of Th17 cells were assessed by FCM after different stimulating time points (4 ,6 ,8 ,10 ,12 h) .The mean fluorescence in-tensity(MFI) and percentage of the ratio of CD4 positive cells on the cellular surface and inside cell membrane were measured be-fore and after PMA stimulation .Results The frequency of Th17 cells was highest with the good stimulation effect under the condi-tion of PMA 150 ng/mL and ionomycin1μg/mL stimulation for 6 h (P<0 .05) .MFI of CD4 inside cellular membrane after stimula-tion was lower than that in the cells with stimulation after labeling membrane surface CD 4(P<0 .05) ,and the Th17 cell frequencies and the ratio of CD4 positive cells were higher than those in the latter ,but the differences were not statistically significant (P>0 .05) .Conclusion After stimulating whole blood with the final concentration of PMA 150ng/mL and ionomycin1μg/mL for 6 h , measuring intracytoplasm CD4 and IL-17 levels is the simple and effective method for detecting the frequency of human Th 17 cells .

[Objective]To investigate the chondrogenic ability and feasibility of bone mesenchymal stem cells(BMSCs) in three kinds of cellular carrier.[Method]BMSCs were separated and cultured into the third generation,which were cultivated in three knids of carriers by multi-point injection into and dropping on the surface of carriers(fibrin collagen sponge,group A;fibrin collagen sponge and FGF,group B and gelatin sponge,group C).All samples were analyzed after four weeks.[Result]There were a few chondrogenic cells in group A,much more chondrogenic cells in group B,and no cells in group C.According to analysis with SPSS 10.0 software,There were more cartilage cells(92.75?10.57) in group B than in group A(36.45?8.34).It was statistical different(P

Objective To study the effect of thoraco-tumba fracture with pedicle scre system. Methods Forty-two cases with thorac-lumbar fractute treated with pedicle scre system were reviewed,their clinical featuers,x-ray and CT images before and after operation were analyzed. Results With follow-up of two months to three years after operntion,height of vertebra was completely restored on thirty-four cases,neurological function recovered in various degree according to the Frankel criteria in all cases. Conclusion Pedicle scre system is an effective method for treatment of thoraco-tumbar fracture.

Objective To investigate the correlation between the expression of human leukocyte antigen B27(HLA-B27)antigen and ankylosing spondylitis(AS),and its implications for the diagnosis and differential diagnosis of AS.Methods Flow cytometry was used to detect HLA-B27.354 suspected AS patients,35 patients final diagnosed with AS and 30 patients diagnosed with rheu-matoid arthritis(RA)were enrolled in the study.Results The positive rate of HLA-B27 in 354 patients with suspected AS was 22.0%,in patients diagnosed with AS was 85.7%,which was higher than the RA group(P <0.05).In AS patients,Males accoun-ted for 77.1%,females accounted for 22.9%,and the patients′age mainly concentrated in youth.The sensitivity and specificity of HLA-B27 test was 85.7% and 100.0% respectively in the diagnosis of AS.Conclusion HLA-B27 antigen detection is important for early diagnosis and differential diagnosis of AS patients.
