Objective To explore the relationship between Helicobacter pylori(Hp) infection and serum homocysteine(Hcy) level ,carotid intima-media thickness and plaque stability in carotid atherosclerosis cases .Methods 206 carotid atherosclerosis pa-tients were collected between March 2012 and January 2013 in our hospital .According to the results of 14C urea breath test ,all the subjects were divided into Hp infection group and non-Hp infection group .And according to the degree of carotid artery atheroscle-rosis ,patients with Hp infection were divided into carotid intima-media thickness thickening group ,stable plaque group and unstable plaque group .The serum Hcy level was detected by enzymatic cycling method ,and the relationship between Hp infection and serum Hcy level ,carotid intima-media thickness and plaque stability in carotid atherosclerosis cases were analyzed .Results Serum Hcy level and carotid carotid intima-media thickness of patients with carotid atherosclerosis in Hp infection group were higher than those in non-Hp infection group(P<0 .01) .The differences in constitution ratio of patients with different types of carotid atherosclerosis in Hp infection group and non-Hp infection group was statistically significant(χ2 =15 .939 ,P=0 .000 3) .In Hp infection group , there were statistically of serum Hcy levels among carotid intima-media thickness thickening group ,stable plaque group and unsta-ble plaque group(P<0 .01) .Linear correlation analysis showed that the serum Hcy level and carotid intima-media thickness were positively correlated in Hp infection group(r=0 .731 ,P<0 .01) .Conclusion Hp infection is likely to promote the development and progression of atherosclerosis through influencing Hcy metabolism and increasing carotid intima-media thickness and instability of carotid atherosclerotic plaque .

Objective To explore the feasibility and validity of Satir model on compulsory drug rehabilitation for female drug users in closed settings. Methods Satir Model-based group psychotherapy was adopted in the treatment on 33 female drug users. Results The findings are that the pre-treatment SCL-90 scores were all higher than norm,indicating very high significant differences(P＜0.01) ; while the post-treatment SCL-90 scores,except the score of somatization, were approximate to norm, showing no statistical differences(P ＞0. 05). Conclusion Satir model played a positive role in the process of female drug users mental health recovery.

Objective To compare the clinical efficacy and safety following the topical application of pazufloxacin mesylate eye drops with levofloxacin eye drops (LOFX) for bacterial conjunctivitis.Methods A multicenter,randomized,investigator-masked,parallel-controlled clinical trial was performed.Five hundred and twenty eyes of 520 patients with bacterial conjunctivitis were enrolled from March to October 2008 in seven ophthalmic centers in China.The patients were randomized into trial group and control group in 3 ∶ 1 ratio with the 390 eyes in the trial group and 130 eyes in the control group.Pazufloxacin mesylate eye drops was topically used 4 times per day for consecutively 7-14 days in the trial group,and levofloxacin eye drops was used in the same way in the control group.Microbiological cultures for conjunctiva sac secretions and drug sensitive test were carried out before and at the end of the administration of eye drops.The signs and symptoms were observed and scored before treatment and 0,3,7 and 14days after treatment.The adverse events following the administration of the eye drops were evaluated and compared.Results The intention to treat analysis (ITT) showed that the cure rate was 59.38％ in the trial group and 60.47％ in the control group,with the effective rate 88.80％ and 86.05％,respectively,with an insignificant difference between the two groups (x2 =0.12,P =0.72).The clinically evaluable analysis (CE) exhibited that the cure rates were 63.48％ in the trial group and 63.87％ in the control group,with the effective rate 92.46％ and 88.24％,whichwas not significantly different between them (x2 =0.54,P=0.46).The modified-ITT analysis (mITT) showed that the cure rates were 60.57％ in the trial group and 62.07％ in the control group,with the effective rate 90.32％ and 88.51％,without significant difference between the two groups (P＞0.05).Based on microbiologically evaluable analysis (ME),the clinical cure rates were 63.71％ and 63.41％ in the trial group and control group,and the effective rates were 93.44％ and 90.24％,respectively.There was no significantly difference between the both groups (P＞0.05).In the trial group and control group,the bacterial eradication rate was 89.42％ and 90.80％ based on ITT,90.11％ and 92.77％ based on CE,respectively.There was no significant difference in incidences of adverse events following the administration of the drug between the trial group and control group,including ocular tolerance,burning sensation,pricking and itching (P =0.34).Conclusions The effectiveness and adverse response were resemble between Pazufloxacin mesylate eye drops and LOFV following the topical application for bacterial conjunctivitis,which indicate that Pazufloxacin mesylate eye drops is effective and safe.
