Objective To assess the prediction value of nonbronchial systemic arterial supply in hemoptysis patients with non-enhanced CT. Methods Fifty-six consecutive patients with hemoptysis underwent non-enhanced CT. Thickness of pleural adjacent to parenchymal lesion larger than 3 mm was regarded as index of nonbronchial systemic arterial supply. Conventional angiography was used as the standard of reference. CT findings were compared with those of conventional angiography. The sensitivity, specificity, and accuracy of CT for predicting nonbronchial systemic arterial supply were assessed. Results The sensitivity, specificity and accuracy of CT for predicting nonbronchial systemic arterial supply were 72.73%, 95.00% and 91.11%, respectively. Sensitivity was higher when nonbronchial systemic arterial supply located in superolateral and posterolateral lung, and lower in anteromedial and inferior lung. Specificity and accuracy were high for predicting nonbronchial systemic arterial supply in every locations. Conclusion Non-enhanced CT can predict nonbronchial systemic arterial supply in patients with hemoptysis, which is helpful for selecting angiography and embolization.

Objective To explore the suicide ideation and related factors in elderly with depressive disorder.Methods A sample of 60 old patients meeting the criteria of ICD-10 for depressive disorder and 60 normal controls were assessed by the Self-rating Idea of Suicide Scale(SIOSS),Trait Coping Style Questionnaire (TCSQ),Self-Rating Anxiety Scale(SAS),Self-Rating Depression Scale(SDS) and Pittsburgh Sleep Quality Index(PSQI).Results The score of despair factor,optimistic factor,sleep factor,conceal factor and total score of SIOSS in patients with depressive disorders (6.22±3.28,2.43± 1.47,1.87± 1.58,1.17± 1.1 1 and 10.51±4.91,respectively) were significantly higher than those of normal controls(t=5.83-14.03,P＜0.01).The scores of SIOSS in patients were significantly positively related with the scores of SAS,SDS,PSQI and N C (r=0.311-0.792,all P＜0.05),but negatively related with the scores of PC(r=-0.761,P＜0.01).Moreover,regression analysis showed that the suicide ideation was increased in accordance with serious depression,anxiety,sleep quality,higher level of education and decreased ability to positive response in elderly with depressive disorder(R 2=0.853,F=62.768,P＜0.01).Conclusion The suicide ideation in elderly with depressive disorder is more serious than that of normal people,and may be influenced by depression,anxiety,sleep quality and coping style.

Objective To explore the effect of Latexin (Lxn) gene transfection on proliferation of CD13;MIAPaca-2 pancreatic cancer stem-like cells.Methods CD133+ MIAPaca-2 cells were isolated and sorted by magnetic activated cell sorting from pancreatic cancer MIAPaca-2 celt line.CD133+ MIAPaca-2 cells were cultured in serum-free medium and the capacity for proliferation,and tumorigenicity of CD133+ MIAPaca-2 cells was determined by the floating spheres test and tumor xenograft assays.The CD133+ MIAPaca-2 cells were transfected with Lxn plasmid (1,3,5 μg).After transfection,the protein and mRNA expression of Lxn in CD133+ and CD133+-MIAPaca-2 cells were detected by Western blotting and RT-PCR,respectively.Cell proliferation was assayed by CCK-8.Results CD133+ MIAPaca-2 cells were successfully isolated,and it grew into a ball-suspended way,the tumorigenicity rate in nude mice with subcutaneous injection 1 × 105 cancer cells was 100％.After Lxn plasmid transfection,the expression of Lxn in CD133+ MIAPaca-2 cells was increased in a dose dependent manner,the Lxn protein and mRNA expression of tumor cells transfected with 5 μg plasmid was 20.80 ±0.98,16.80± 2.73,which was significantly higher than that in non-transfected cells (1.02 ± 0.01,1.01 ± 0.01),and the difference between the two groups was statistically significant (P ＜ 0.05).After transfection,cellular proliferation activity also showed a transfection dose and culture time-dependent decrease,the inhibition rate of tumor cells transfected with 0.4 μg plasmid was 36.2％,which was significantly different from that in non-transfected cells (P ＜ 0.05).Conclusions CD133+ MIAPaca-2 pancreatic cancer cells have some characteristics of cancer stem cells.Lxn gene transfection can inhibit the proliferation of CD133+ MIAPaca-2 cells.

Purpose To study the expression of HNF-1β in different type ovarian carcinoma and to explore the diagnostic value of HNF-1β in the diagnosis of ovarian clear cell carcinoma. Methods Immunohistochemical EnVision method was used to detect the ex-pression of HNF-1βin 27 clear cell carcinomas, 35 high-grade serous carcinomas, 21 endometrioid adenocarcinoma, 10 mucious carci-nomas, 13 metastatic Krukenberg tumors, and 2 transitional carcinomas. Results All of ovarian clear cell carcinomas variably ex-pressed HNF-1β and the positive rate of HNF-1β in ovarian cleat cell carcinoma was 85. 2%. Of 21 ovarian serous carcinomas, the nuclear positive of HNF-1β was 4 and HNF-1βpositive rate was 2. 9%. There was 5 HNF-1βexpression in endometrioid adenocarci-noma and the positive rate of HNF-1β was 23. 8%. The positive rate of HNF-1β in mucious carcinoma and metastatic Krukenberg tumor was 60. 0% and 53. 8%, respectively. No HNF-1βexpression was seen in transtional cell carcinoma. The sensitivity and speci-ficity of HNF-1β in the diagnosis of ovarian clear cell carcinoma was 85. 2% and 76. 5%. Conclusions HNF-1β may be a higher sensitive marker for the diagnosis of ovarian clear cell carcinoma. The diffuse and strong positive of HNF-1βmay have higher specific for diagnosis of ovarian clear cell carcinoma.

Objective To evaluate clinical effects of integrated traditional Chinese and western medicine therapy for epilepsy after stroke. Methods Literatures about the treatment of epilepsy after stroke with the combination of traditional Chinese medicine and western medicine which come from the database such as CNKI, VIP, WanFang and Pubmed, were studied and all the randomized controlled trials on comparing therapeutic effects of treating epilepsy between combined treatment of TCM and western medicine and western medicine were enrolled. The Cochrane Collaboration's software RevMan 5 was used for meta-analysis. Results 7 articles were included in the study, there is homogeneity among these articles(P>0.05), The fixed effect model was used for the meta analysis. the combined results were OR=5.17, 95%CI(3.02, 8.82), the overall effect of test Z=6.01, P<0.01, the difference between the treatment group and the control groups was significant, that means the overall effect of the combination of traditional Chinese medicine and Western medicine treatment was better than western medicine treatment; Funnel plot graphic displayed asymmetrically, which indicated the literatures publication bias. Conclusion The current data indicate that the curative effect of TCM and west medicine combined treatment is better than pure western medicine therapy for epilepsy after stroke, but as the literature publication bias, clinical studies need more high quality large samples to prove this conclusion.
