The researches on attention provide a promising framework for studying bipolar disorder pathophysiology and treatment.Previous findings have shown the negative attention bias maybe a risk factor for bipolar disorder.The current review discusses this issue in several aspects,including attention bias toward emotional information in bipolar disorder is state or trait,and whether shows mood-congruent bias;the character of attention bias in the different episodes of bipolar disorder.The article also puts forward an intervention of attention bias modification for treating bipolar disorder.

Objective To establish a carotid artery stenosis model by endovascular technique suitable for neuro-interventional therapy.Methods Twelve dogs were anesthetized, the unilateral segments of the carotid arteries' tunica media and intima were damaged by a corneous guiding wire of home made. Twenty-four carotid artery stenosis models were thus created. DSA examination were performed on postprocedural weeks 2, 4, 8, 10 to estimate the changes of those stenotic carotid arteries. Results Twenty-four carotid artery stenosis models were successfully created in twelve dogs. Conclusions Canine carotid artery stenosis models can be created with the endovascular method having variation of pathologic characters and hemodynamic changes similar to human being. It is useful for further research involving the new technique and new material for interventional treatment.

Objective To investigate the relationship between recurrent vulvovaginal candidiasis (RVVC) and personal behavior and life style.Method Seventy-two patients with RVVC and 72 normal healthy women were studied with questionnaire by case-control design.Results Analysis by univariate unconditional logistic regression showed that contraception (OR=0.266), frequently changing and washing one’s underpants (OR=0.378), vaginal douche (OR=1.881), sharing bath towel with others (OR=1.872), sharing underpants with others (OR=6.163) and cigarette smoking or passive smoking (OR=3.164) were significantly associated with RVVC at significance level of 0.05. Analysis by multivariate unconditional logistic regression showed that contraception (OR=0.219), frequency of sexual intercourse (OR=1.806), use of sanitary napkins without guaranteed quality (OR=1.844), self-vaignial douche (OR=1.911) and cigarette smoking or passive smoking (OR=2.875) were associated with RVVC at significance level of 0.15.Conclusions Poor personal hygiene and unhealthy life style were important factors attributed to RVVC. It is suggested to promote correct personal hygienic behavior and healthy life-style in women by health education in order to reduce RVVC.

Objective To discuss the surgical skills and clinical value of laparoscopic splenectomy with a safe approach to the splenic hilum through first mobilizing the lower pole of the spleen.Methods A total of 88 patients with hypersplenism secondary to liver cirrhosis who underwent laparoscopic splenectomy in our department from September 2015 to September 2016 were selected into this study.And these patients were divided into two groups based on whether to take the safe approach to the splenic hilum through first mobilizing the lower pole of the spleen in laparoscopic splenectomy.The control group included 40 cases who underwent the traditonal laparoscopic splenectomy,while the observation group included 48 cases who took the safe approach to the splenic hilum through first mobilizing the lower pole of the spleen in laparoscopic splenectomy.The clinical data were collected retrospectively by medical clinical records review.Results There was no mortality occurred in this study.The blood loss of the observation group was (247.50±135.89)mL,which was obviously lower than (361.75±144.43)mL of the control group,and the difference was statistically significant (P<0.05).The operation time of the two groups were (194.69±47.99)min and (232.75±45.26)min respectively,and the difference was statistically significant (P<0.05).No significant difference was found in terms of rate of conversion to laparotomy,rate of intraoperative blood transfusion,postoperative hospital stay and complications (P>0.05).Conclusion It is very crucial for a safe approach to the splenic hilum through first mobilizing the lower pole of the spleen to establish a tunnel behind the splenic hilum in laparoscopic splenectomy.It is safe and feasible to perform a safe approach to the splenic hilum through first mobilizing the lower pole of the spleen in laparoscopic splenectomy.The technique is generalized in clinics,especially for freshmen.

Sera were collccted from mice immunized separately with schizonts, merozoitcs or different parasite stages, or from mice which had been recovered from Plasmodium yoelii yoelii infection. The effect of protection of cach serum against P. y. infection was assayed by passivc transfer technique. It was shown that only sera collected from mice which either had been trcated with chloroquine or had been naturally recovcred from P. y. infections can transfer certain dcgree of resistance to normal mice. The cffectivc sera delayed the appearance and the peak of parasitemia, and prolonged the survival time of the challenged mice. After these sera were fractionatcd by 50%(NH4)2SO4 precipitation, the prccipitated fraction showed similar degree of protection as the non-fractionated sera. Chloroquine-treated serum was shown to be able to inhibit the invasion of new erythrocytes by marozoite in vitro. 35S-methionine-labelcd antigens were precipitated by protective or non-protective sera and the bands were compared on SDS-PAGE and autoradiogram. Since thc antigcn bands of 245, 210, 190, 156 and 130 KD can only bc precipitated by protective sera but not by non-protectivc sera, it is possible that the protection of chloroquine-treated serum is induced by the specific antibodies against the above antigens.

Osteosarcoma is the most common maligant in skeletal system.Its treatment is always the focus of most clinical research workers.This article is a brief overview of the research progress of the therapy for osteosarcoma.In addition to neoadjuvant chemotherapy,surgical treatment,this article also includes molecular targeted therapy,gene therapy,and immune therapy.These new advances will contribute to the clinical work.

Aim To study the protective effects of curcumin on myocardial reperfusion injury in rats.Methods Myocardial ischemia reperfusion injury model was established through occluding the left anterior descending branch of coronary artery for 60 min and removing the ligation later to reperfuse for 30 min in vivo.Different doses of curcumin were administered through intravenous injection 5 min before the onset of ischemia.The changes of hemodynamics were recorded and myocardial infarct sizes were measured.Results Curcumin(20,40 mg?kg~(-1))improved the hemodynamics during myocardial ischemia reperfusion in a dose-dependent manner,as shown by the significant increase in LVSP and?dp/dt_(max) and the decrease in LVEP.Moreover,curcumin reduced the myocardial infarct sizes.Conclusion Curcumin exerts protective effects on myocardial ischemia reperfusion injury.

Objective To evaluate the scan technique and clinical value of multi-slice spiral CT angiography(MSCTA) of coronary artery.Methods MSCTA was performed in 86 patients,and 25 of them were also investigated with selective coronary angiography(SCA).The imaging quality of MSCTA in different scanning condition were analyzed.The patency of coronary artery and other branches were examined.The distribution and extent of coronary arterial stenoses were assessed.The findings demonstrated on MSCTA were compared with those seen on SCA.Results(1)The imaging quality on MSCTA of coronary artery was significant better in patients with a heart rate below 60 beats per minute,contrast flowing rate 3.0~3.5 ml/s,volume 120~150 ml and delayed time 22~25 s;(2)in 25 cases,of 71 coronary artery and branches without stenoses examined with MSCTA,68 had identical appearance on both MSCTA and SCA.The distribution and extent of 19 coronary arterial stenoses revealed by MSCTA were correlated exactly with SCA in 29 coronary arterial stenoses.The negative and positive predicted value were 95.8% and 65.5% respectively.Sensitivity,specificity and accuracy were 86.4%,87.2% and 87.0% respectively.Conclusion MSCTA as a noninvasive examination is a valuable method in detecting diseases or variations of coronary artery.
