Cigarette smoking is the most important preventable cause of death in Korea. Smoking should be considered as a chronic disease attributed to nicotine dependence which needs a long term care. Nicotine dependence and withdrawal symptoms are major barriers to smoking cessation and can be successfully managed by pharmacotherapy. There are two types of pharmacotherapy for nicotine dependence, nicotine-replacement therapy(NRT) and nonnicotine-replacement therapy. Nicotine, which can be administered by patch, gum, inhaler, and nasal spray, doubled the smoking cessation rate. NRTs are usually well tolerated. Sustained-release bupropion, an antidepressant, doubled the smoking cessation rate when combined with counselling. Bupropion can induce seizure in less than 0.1% by lowering the seizure threshold. Nortriptyline and clonidine can be used as second line drugs for smoking cessation. They are similar in efficacy compared to NRT or bupropion but they frequently have adverse drug reactions. Combination of bupropion with NRT is more efficacious than NRT alone but not more effective than bupropion alone. There is no convincing evidence to recommend a specific drug for smoking cessation in women. NRT and bupropion can be useful in special situations for adolescent smokers, but evidence is not enough to recommend pharmacotherapy for adolescent smokers. Weight gain is the main barrier to smoking cessation, especially in women. Vigorous exercise reduced weight gain. Nicotine gum, bupropion also temporarily reduced weight gain after smoking cessation, but only while the drug was being administered. As there are sound evidences for the effect of pharmacotherapy in smoking cessation, it is necessary for physicians to integrate it into their daily practices.

Objective To study the effect of femoral offset reconstruction ON the Harris hip score and the hip ROM (range of motion) after artificial hip replacement in femoral neck fractures. Methods Follow-ups were conducted for 47 patients who had undergone artificial hip replacements for their unilateral femoral neck fractures. We took X-ray pictures to compare the femoral offsets at the affected and unaffected hips. The operated hips were evaluated by the Harris hip score. Statistical analyses were performed with SPSS l2.0 software. Results The Harris hip score of the operated hip was positively related to femoral offset reconstruction(t=7.25,P＜0.001).There was a significant and positive correlation between femoral offset and the hip abductor ROM(r=0.80,P＜0.001).The rate of femoral offset reconstruction had no significant difference between total hip arthroplasty and bipolar hip arthroplasty (χ2=0,P＞0.05).Conclusions Reconstruction of femoral offset after artificial hip replacement in the femoral neck fractures can improve funetional recovery and ROM of the hip. Femoral offset reconstruction is uncorrelated to the selection of total hip arthroplasty or bipolar hip arthroplasty.

Objective To evaluate the performance alarms and parameters generated by hematology analyzer during detection of circulating sezary cells of peripheral blood smears.Methods Blood samples from patients with Sezary syndrome (n=21) were studied with Sysmex XN-9000 analyzer,and compared to patients with benign or tumoral skin lesions (n=48) and patients with chronic lymphoproliferative B-cell diseases (n=55) and normal person (n=45) used as control.Results In present series,the value of structural lymphoid parameters (ly-x and ly-z) and the alarm Blast/Abn Lympho were statistically higher in Sezary cases than in control cases (U=37,40,44,55,38,41,all P＜0.05).Screening Sezary cells critical values of ly-x and ly-z determined by ROC curve were greater than or equal to 86 and was more than or equal to 68.The combination of above three indexes up (i.e.alarm Blast/Abn Lympho＞ 100,ly-x=86 and ly-z＞68) sensitivity and specificity respectively for 100 ％ and 92.1 ％,in order to get the best screening Sezary cells diagnostic efficiency.In addition,the value of ly-x was associated to the count of circulating Sezary cells and value of ly-z to the presence of large Sezary cells,both parameters described as prognostic factors.Conclusion The combination of alarm Blast/Abn Lympho and structural parameters (ly-x/ ly-z/ly-y) may allow to define rule of blood slide review to screen circulating Sezary cells.

Objective: To evaluate the efficacy and safety for the application of low-dose vitamin K antagonist (VKA) during whole pregnancy and low-molecular-weight heparin/heparin at early pregnancy in patients after mechanical heart valve replacement. Methods: We searched the Cochrane library (2016 Issue 2), PubMed, EMbase, CBM, Tsinghua Tongfang (CNKI), Wanfang and VIP databases to collect the literatures for the application of low-dose VKA during whole pregnancy and low-molecular-weight heparin/heparin at early pregnancy up to 2016-06. The literatures were independently screened by 2 reviewers and Meta-analysis was performed using RevMan 5.3 software. Results: 12 studies were finally enrolled. Meta-analysis presented that compared with the application of low-molecular-weight heparin/heparin at early pregnancy, low-dose VKA during whole pregnancy showed decreased valvular thrombosis rate (OR=0.26, 95% CI 0.13-0.54, P<0.001), lower spontaneous abortion rate (OR=1.99, 95% CI 1.21-3.26, P=0.006) and increased fetal abnormality rate (OR=3.39, 95% CI 1.11-10.37, P=0.03); while the maternal mortality (OR=0.79, 95% CI 0.24-2.58, P=0.70), peri-natal bleeding rate (OR=0.56, 95% CI 0.27-1.18, P=0.13) and the incidence of stillbirth (OR=1.80, 95% CI 0.94-3.44, P=0.07) were similar between two conditions. Conclusion: Current evidence indicated that the application of low-doseVKA during whole pregnancy decreased the rates of valvular thrombosis and spontaneous abortion in patients after mechanical heart valve replacement, while increased the rate of fetal abnormality. Further investigation is needed to confirm the above conclusion.
