Objective To better understand the knowledge, attitude, practice status of sexual dysfunction (SD) in medical staffs in field of reproductive health in Tianjin. Methods Using random, stratified and clustered sampling ap-proach, we selected 507 medical staffs in field of reproductive healthcare in Tianjin. Self-administered questionnaire on sex-ual dysfunction KAP was employed to survey the general condition, to understand SD knowledge and their attitude to SD, to perceive SD prevalence of the medical staffs and their demand to sexual dysfunction training. Results The people who re-spond to our survey had high awareness to SD, but they are lack of knowlege in mechanism on sexual behavior and female SD related knowledge. Multiple-factor analysis indicated that young age group respondants(β=-0.827,P=0.018)and medical staffs from high-tier medical institutions (β=-0.223, P=0.048) showed higher awareness. When they suffered SD, 49.28%re-spondants would see doctor immediately, 36.85% informants chosen temporary observation, and 9.73% informants shown negative altitude. Minority (17.14%) of medical staff are able to confirmed SD to themselves and 90.48% of medical staff de-mand training on SD related knowledge. Conclusion It’s necessary to perform continuing education to medical staffs via different intervention, so as to improve their cognitive level and attitude to SD, and these can help them providing better ser-vice to their patients and the public.

Objective To investigate the expression and clinical significance of BRMS1 ( breast cancer metastasis suppressorl ) protein in colon cancer.Methods The expression of BRMS1 protein was detected by using EliVision immunohistochemical techniques in 46 cases of colon cancer,and adjacent non cancerous colon tissues.The clinical significance with histopathologic records was aralyzed.Results The expression levels of BRMS1 ( 34.8％ ) in the colon cancer tissues was significantly lower than those of adjacent non cancerous colon tissues( x2 =23.92,P ＜0.01 ).The expression of BRMSl was significantly correlated with tumor size,clinical stage,and lymph node status (x2 =6.02,4.28,4.35,all P＜0.01) ;BRMS1 had no correlation with age,pathological type.Conclusion BRMS1 might synergistically promote the metastasis of colon cancer.Detection of the expression of BRMS1 may be hdpful in determineing the prognosis of colon cancer.

Objective To compare the pros and cons of endoscopic papillary balloon dilation (EPBD) with those of endoscopic sphincterotomy (EST) in the treatment of common bile duct stones.Methods We searched The Cochrane library,Medline,Pubmed,Embase,CBM,CNKI,VIP and Wan Fang database in any language.RCTs that compared EPBD with EST for the removal of common bile duct stones were included from January 1983 to September 2012 and qualities of the trials were evaluated.Statistic analyses were carried out using RevMan 5.1 software.Results A total of 18 randomized trials with 2385 participants met our inclusion criteria.EPBD compared with EST resulted in similar outcomes with regards to stone removal on 1 st attempt,overall stone removal,perforation,total short-term complication,long-term cholangitis or mortality.EPBD carries a higher risk of pancreatitis (RR =1.99,95％ CI:1.41-2.81) and severe pancreatitis (RR =4.68,95 ％ CI:1.36-16.11),and requires higher rates of mechanical lithotripsy (RR =1.31,95％ CI:1.14-1.50).Conversely,EPBD not only has statistically significant lower rates of bleeding (RR =0.14,95％ CI:0.06-0.34),but also leads to significantly less long-term cholecystitis (RR =0.38,95％ CI:0.19-0.76),long-term stone recurrence (RR =0.67,95％ CI:0.47-0.96) and total longterm complications (RR =0.52,95 ％ CI:0.40-0.67).Conclusion On the basis of lower rates of bleeding or long-term complications,EPBD should be the preferred strategy over EST for endoscopic management of common bile duct stones,however,the rate of pancreatitis,especially the severe pancreatitis is higher with EPBD.

Objective To analyse the CT features of solitary bronchioalveolar carcinoma(SBAC) so that to improve the CT diagnostic accuracy.Methods CT findings of 39 cases with SBAC proved by operation and pathology were studied,and an analysis as compared with 48 cases other type of peripheral pulmonary carcinoma.Results CT findings included lobulations in 32,spiculation in 33,pleural tags in 25,bronchovascular bundles in 14,vacuole or/and bronchiologram in 18 and ground glass changs in 8 cases.Conclusion The characteristic CT manifestations of SBAC are:(1)Vacuole or/and bronchiologram;(2)Long spiculation;(3)Ground-glass.It is important to recognize the CT appearances of SBAC in order to improve diagnostic ability.

OBJECTIVETo assess the clinical outcomes of balloon kyphoplasty assisted with calcium phosphate cement (CPC) in treating osteoporotic vertebral fractures (OVF).

METHODSFrom January 2009 to January 2011, 26 patients with osteoporotic vertebral fractures were treated with balloon kyphoplasty assisted with CPC, including 31 vertebrae. There were 15 males and 11 females with an average age of (71.67 +/- 4.36) years old (ranged from 60 to 89 years). Course of disease was from 0.5 to 7 days with an average of 3.2 days. Clinical outcomes were assessed by the visual analogue scale (VAS) and the oswestry disability index (ODI). Vertebral height loss and kyphotic angle were measured by X-rays.

RESULTSAll patients were followed up for 10 to 24 months with an average of 18 months. Before operation, 24 hours after operation and at final follow-up, VAS scores were 7.91 +/- 1.20, 3.22 +/- 1.12, 1.92 +/- 0.83, respectively; ODI scores were 40.00 +/- 1.15, 17.00 +/- 2.12, 13.00 +/- 1.42, respectivesly; vertebral heights were (18.21 +/- 3.21), (23.82 +/- 3.10), (21.85 +/- 3.24) mm, respectivesly; vertebral kyphosis angles were (18.21 +/- 3.21) degrees, (7.42 +/- 3.13) degrees, (10.01 +/- 3.11) degrees, respectivesly. There was significant difference between preoperation and 24 hours after operation, and between final follow-up and preoperation (P < 0.05). There was no significant difference between final follow-up and 24 hours after operation (P > 0.05).

CONCLUSIONBalloon kyphoplasty assisted with calcium phosphate cement (CPC) is effective for the treatment of osteoporotic vertebral fractures (OVF), which can expeditiously relieve pain and effectively rebuild height of vertebral body and kyphotic angle, and also has advantages of minimal trauma and good security.

ObjectiveTo evaluate the late-phase enhancement of carotid artery in patients with cerebral infarction by contrast-enhanced ultrasonography.MethodsSixty-eight patients whose bilateral carotid artery plaques were both wider than 1.5 mm with treatment in Zhejiang Provincial People?s Hospital from April to July in 2013 were enrolled in this study. Among the enrolled patients, there are 50 patients with cerebral infarction including 30 patients with unilateral cerebral infarction and 20 patients with bilateral cerebral infarction, and 18 patients without cerebral infarction. The enrolled patients underwent conventional and contrast-enhanced ultrasonography. The time-intension curve was obtained till 6 minutes after the injection of contrast agent. The late-phase enhancement intensity and relative intensity of maximal carotid plaque was measured and calculated. The differences of late-phase enhancement intensity and relative intensity between patients with cerebral infarction and patients without cerebral infarction, and between ipsilateral and contralateral side of cerebral infarction in patients with cerebral infarction were compared using two samplet test.ResultsThe late-phase enhancement intensity of carotid plaque in patients with cerebral infarction and in patients without cerebral infarction was (6.0±1.5) and (4.9±1.2) dB, respectively, and the relative late-phase enhancement intensity of carotid plaque was 0.9±0.2 and 0.8±0.2, respectively. The late-phase enhancement intensity and the relative intensity of carotid plaque was higher in patients with cerebral infarction compared with patients without cerebral infarction, and the differences had statistical significance (value oft was 2.132 and 2.258 respectively, value ofP were both less than 0.05). The late-phase enhancement intensity of carotid plaque in ipsilateral and contralateral side of cerebral infarction was (7.1±1.8) and (4.9±1.2) dB, respectively, and the relative late-phase enhancement intensity of carotid plaque was 1.2±0.3 and 0.8±0.2, respectively. The late-phase enhancement intensity and the relative intensity of carotid plaque was higher in ipsilateral side of cerebral infarction compared with contralateral side of cerebral infarction in patients with cerebral infarction, and the differences had statistical signiifcance (value oft was 3.132 and 2.953 respectively, value ofP were both less than 0.01).ConclusionThe late-phase enhancement of carotid plaque in patients with cerebral infarction is significantly different from that in patients without cerebral infarction.
