Objective To investigate the relationship between Livin and Ki-67 proteins, and the expres-sion and clinical significance of Livin and Ki-67 proteins in cholangiocarcinoma. Methods Fifty-five samples of cholangiocarcinoma tissue were collected in Shengjing Hospital from January 2002 to December 2003. The expres-sion of Livin and Ki-67 proteins in the 55 samples of cholangiocarcinoma tissue and 12 samples of chronic cholan-gitis tissue were detected by immunohistochemical assay. The relationship between the expression of Livin and Ki-67 proteins and the clinicopathological parameters of cholangiocarcinoma was analyzed. The results were analyzed by Spearman rank correlation coefficient, chi-square test and t test. Results The positive expression rate of Livin protein in cholangiocarcinoma was 71% (39/55), which was significantly higher than 0 (0/12)in chronic cholan-girls tissue (χ2=20.361, P<0.01). The expression of Livin protein was influenced by the differentiation of cholangiocarcinoma and the lymph node metastasis (χ2=4.193, 4.245, P <0.05). The positive expression rate of Ki-67 protein was 96% (53/55) in cholangiocarcinoma. The label index of Ki-67 in patients in clinical stage Ⅰ,Ⅱ,Ⅲ,Ⅳ,were 22%±16%, 33%±12%, 43%±15%, and 49%±10%, respectively. There was signifi-cant difference in the label index of Ki-67 between patients in clinical stage Ⅰ and those in clinical stages Ⅱ, Ⅲ,Ⅳ(t=2.307, 2.871, 3.957, P<0.05). The label index of Ki-67 was 43%±13 % in patients with local lymph node metastasis, and 34%±16% in patients without local lymph node metastasis, with statistical difference between the 2 groups (t=2.334, P<0.05). The expression of Livin protein in cholangiocarcinoma was positively correlated with the label index of Ki-67 (r=0.502, P<0.01). Conclusions Livin protein plays an important role in the pathogenesis and development of eholangiocarcinoma, and it also has correlation with the proliferating activity of cholangiocarcinoma cells. Combined detection of the expression of Livin and Ki-67 proteins may be helpful in judging the malignancy of cholangiocarcinoma and determining the prognosis of patients.

Objective To identify the correlation factors associated with cerebral intragenic ischemia after temporary parent arterial occlusion in intracranial aneurysm surgery. Methods One hundred and eighteen patients who underwent temporary arterial occlusion in the 120 aneurysms (from a group of 324 consecutive aneurysm patients treated from 1996 to 2002) were reviewed retrospectively. These variables included sex, age, presence of preoperative subarachnoid hemorrhage (SAH), neurological clinical grade, operational timing, duration of arterial occlusion, numbers of temporary occlusion, mode of arterial occlusion, intraoperative aneurysm rupture, hypertension, the location of temporary occlusion, aneurysm size, hyperglycemia, atheromatous mass. Univariate and multivariate were used to investigate the relationship between the variates and postoperative ischemic changes. Results The total times of temporary occlusion were 156, with an average of 1.30. The duration of arterial occlusion ranged from 1 to 45 min (9.75?7.75). Seventeen patients (14.4%) demonstrated evidence of new infarction in the vascular territory subjected to temporary arterial occlusion. Conclusion In the univariate analysis, age, presence of preoperative SAH, duration of arterial occlusion, atheromatous mass are all significantly correlated with postoperative ischemic injuries. Multivariate logistic regression revealed that the age, older more than 60 (P= 0.010 3 , relative risk=4.335), and the duration of arterial occlusion, lasting more than 20 min (P= 0.032 9 , relative risk=4.177), have significant correlation with the injuries. Based on these findings, temporary occlusion is safe and useful in aneurysm surgery and the postoperative cerebral ischemia is less likely to occur when the duration of clipping is shorter than 20 min.

Objective To understand the status of soil?transmitted nematode infections in rural residents so as to provide the evidence for formulating the guidance for prevention and control of the diseases. Methods The national surveillance sites of soil?transmitted nematode infections were established in Shuyang County,Suqian City,Jiangsu Province from 2006 to 2015. At least 1 000 fecal samples of residents aged 3 years or above were collected in every autumn,and the intestinal helminth eggs were detected with the Kato?Katz technique and the Enterubius vermicularis eggs were detected by the cellophane tape method for children aged 3-12 years. The soil samples were collected from vegetable fields,lavatories,courtyards and kitchens to exam?ine Ascaris lumbricoides eggs and larvae of hookworm. Results The infection rates of soil?transmitted nematodes in residents and E. vermicularis in children reduced from 1.81%(19/1 049)and 4.72%(5/106)in 2006 to 0.25%(3/1 180)and 0(0/263) in 2015,respectively,in the surveillance sites. The infection intensity was mild in all the infected cases. The soil samples were negative for detecting A. lumbricoides eggs and hookworm larvae. Conclusion The infection rates of soil?transmitted nema?todes in the residents and E. vermicularis in the children show a decreasing trend and keep at a low level of prevalence in Shuy?ang County.

Objective To explore the long-term predictive value of serum concentration of N-terminal prosoma brain natriuretic peptide (NT-proBNP) in the early acute coronary syndrome (ACS). Methods The 164 patients firstly hospitalized and finally diagnosed as acute myocardial infarction (AMI) were selected, and then the serum concentration of NT-proBNP was determined in less than 12 hours. According to the 75 percentage points of serum concentration of NT-proBNP, the patients were divided into two groups: low concentration group (n = 123) and high concentration group (n = 41 ). The major adverse cardiac events (MACEs) were followed and compared at one month, six months and twelve months between low group and high group. Results At 1-, 6-, 12-month follow-up, the odds ratio (OR) of death event were 4.1, 5.6 and 4.0 in high group respectively, and the nonfatal heart failure occurred in 4, 4 and 7 patients in high group. Multiple factor logistic regression analysis showed that NT-proBNP was an independent risk factor of the MACEs at different periods including short time, middle time and long time in ACS patients (P＜0. 05). Conclusions NT-proBNP is a strong predictor of the long-term MACEs in patients with early ACS.

Since epileptic seizure is unpredictable and paroxysmal, an automatic system for seizure detecting could be of great significance and assistance to patients and medical staff. In this paper, a novel method is proposed for multichannel patient-specific seizure detection applying the earth mover's distance (EMD) in scalp EEG. Firstly, the wavelet decomposition is executed to the original EEGs with five scales, the scale 3, 4 and 5 are selected and transformed into histograms and afterwards the distances between histograms in pairs are computed applying the earth mover's distance as effective features. Then, the EMD features are sent to the classifier based on the Bayesian linear discriminant analysis (BLDA) for classification, and an efficient postprocessing procedure is applied to improve the detection system precision, finally. To evaluate the performance of the proposed method, the CHB-MIT scalp EEG database with 958 h EEG recordings from 23 epileptic patients is used and a relatively satisfactory detection rate is achieved with the average sensitivity of 95.65% and false detection rate of 0.68/h. The good performance of this algorithm indicates the potential application for seizure monitoring in clinical practice.
