Purpose: The aim of the present study was to investigate the expression of breast cancer resistance protein (BCRP) in primary breast carcinoma and to determine whether such expression can predict survival. Methods: Expression of BCRP in 60 breast cancer patients was determined by immunohistochemistry on formalin-fixed, paraffin-embedded tumor section. The relationship between the expression of BCRP with the clinicphathological characteristics and the prognosis of breast cancer patients were also analyzed. Results: ①BCRP expression was observed in 21 of 60 (35%) cases.② BCRP expression was more frequently observed in patients with lymph node metastasis or hormone receptor (P 0. 05) .③Kaplan-Meier analyses revealed that BCRP expression associated only with disease-free survival (DFS) (P 0. 05) . ④In univariate and multivariate Cox regression analyses, tumor size, lymph node metastasis and estrogen receptor (ER) was associated with DFS and OS (P

One-and-a-half syndrome with facial diplegia, also referred to as the fifteen-and-a-half syndrome, is an extremely rare clinical entity caused by involvement of bilateral tegmentum of pons. Herein, we report a 52-year-old male who presented with one-and-a-half syndrome with left facial paralysis, which was consistent with the so-called eight-and-a-half syndrome. Brain magnetic resonance imaging showed pontine infarction. Five days after initiation of antiplatelet therapy, the patient developed right facial paralysis, a diagnosis of fifteen-and-a-half syndrome was made, repeat MR imaging revealed bilateral pontine tegmentum infarction. Fifteen-and-a-half syndrome is a newly proposed concept associated with pontine infarction. The clinicoradiological features of this specific disease are as yet unclear due to its extreme rarity. The current case would help advance the current understanding of the disease spectrum of pontine infarction.

To examine the actual clinical diagnosis capability,the import of computer-based case simulations ( CCS ) technology in medical education is very important.The CCS examination system that integrated the ASP.NET and CCS technology can simulate doctor's clinical course more realistically and realize the students' practical skills evaluation.The system has a good prospect in medical education and clinical skills training.

Objective To explore the correlation between non-Hodgkin lymphoma (NHL) and hepatitis C virus (HCV) infection.Methods HCV infection of 208 NHL patients was investigated from the Affiliated Tumor Hospital of Zhengzhou University.Patients with leukemia or other tumors,and healthy people were used as the control and were pair matched on age and gender.ELISA method was used to detect the HCV-antibody in serum.Results HCV-antibody positive rate in NHL patients [11.5 ％ (24/208)] was significantly higher than those in leukemia patients [3.8 ％ (8/208)] (x2 =8.667,P =0.003),patients with other tumors (6/208,2.9 ％) (x2 =11.639,P =0.001) and healthy people [1.0 ％ (2/208)] (x2 =19.856,P =0.000).Conclusion HCV infection is related to NHL in Henan area.

Background and purpose:Thermal ablation (radiofrequency ablation, RFA/microwave ablation, MWA) is the most commonly used minimally invasive technique for the treatment of liver cancer. Real-time shear wave elastography (SWE) is a new type of ultrasonic imaging technology, which was used in our study to monitor thermal ablation of liver cancer. This study aimed to investigate the stiffness change of liver cancer and that of surrounding liver parenchyma before and after thermal ablation, and to evaluate the application of SWE for monitoring thermal ablation for liver cancer.Methods:From Oct. 2014 to Apr. 2015, a total number of 36 patients, with 39 lesions, were treated with RFA or MWA and got complete response. SWE examination was performed before and after ablation. The SWE-mean, SWE-min, SWE-max, SWE-SD of lesions and the surrounding liver parenchyma were measured. Statistical analysis was made to compare the stiffness changes of liver cancer with those of the surrounding liver parenchyma before and after thermal ablation, and to determine whether there were differences between two different ablation modes.Results:Before and after ablation, the SWE-mean of lesions was (30.09±11.67) kPavs (52.11±17.56) kPa,SWE-min was (10.46±8.22) kPavs (20.57±11.42) kPa, SWE-max was (51.50±20.84) kPavs (88.54±27.75) kPa, SWE-SD was (10.63±4.30) kPavs (16.89±7.72) kPa; There were statistically signiifcant differences (P<0.05). Before and after ablation, the SWE-mean of surrounding liver parenchyma was (8.84±2.82) kPavs (8.91±2.78) kPa, SWE-min was (4.77±1.95) kPavs (4.69±1.90) kPa, SWE-max was (13.82±3.79) kPavs (14.34±3.97) kPa, SWE-SD was (3.24±1.32) kPavs (3.37±1.29) kPa; There were no statistically signiifcant differences (P>0.05). After ablation, the SWE-mean of RFA and MWA was (45.55±10.91) kPavs (60.59±20.99) kPa, SWE-min was (18.95±8.86) kPavs (25.93±10.93) kPa, SWE-max was (76.58±15.51) kPavs (104.01±32.59) kPa, SWE-SD was (13.82±3.52) kPavs (20.85±9.77) kPa; There were statistically signiifcant differences (P<0.05).Conclusion:SWE can quantitively analyze the stiffness of lesions. The ablation zone became stiffer after RFA or MWA, and the ablation zone of MWA was stiffer than that of RFA. Two kinds of ablation methods did not signiifcantly affect the stiffness of liver parenchyma around the lesion. SWE could potentially be used to monitor thermal ablation of liver cancer.

Objective To understand and analyse the epidemic status of human intestinal nematode infection in Jiangsu Province, so as to provide basis for making control measures. Methods The typical thirty-nine spots in thirteen counties among the sampling spots of National Investigation on Distribution of Human Parasites in 1990 were selected and investigated according to the Methods of National Investigation Scheme on Human Principal Parasites in 2004. Results The total prevalence was 3.88%, which decreased by 46.92% compared with the investigation in 2002 (7.31%). The infection rates of hookworm, Ascaris and Trichuris were 1.14%, 1.06% and 1.73%, respectively, and the proportion of light infection was 91.75%. The rate of multiple infections was 9.40%. The proportion of hookworm infection was 78.06% in Southern Jiangsu and the proportion of Ascaris or Trichuris was 89.03% in Northern Jiangsu. The infection rate of Enterobius was 3.72% among children aged less than 12 years. Conclusions The prevalence of intestinal nematodes has decreased to lower level in Jiangsu Province. The difference of prevalence in different regions has a relationship with the disease control and social-economic, culture and health levels. The principal control work should be still put in the northern part of Jiangsu Province. The preschool children and the middle and old age peasants are high-risk population. The different control measures should be taken in accordance with the situation of different regions in the future.

Objective To investigate and analyze the changes of Ascaris lumbricoides infection in rural residents of Jiangsu Province during 13 years and its influencing factors in order to provide the basis of making practical policies for ascariasis control in future. Methods The data were analyzed about the rates of Ascaris infection and mass chemotherapy, per capita income, and the rates of the use of running water and hygienic toilets in the southern part, the middle part and the northern part of Jiangsu Province from 1990 to 2002, and the main influencing factors for Ascaris infection were explored. Results The prevalence rate of Ascaris infection decreased continuously during 13 years, from 39.51% to 2.14%, and the decrease rate was 94.58%. In 2002, the infection rate was the lowest, only 0.41%, decreased by 98.92% in the middle part of Jiangsu Province, and the infection rate was the highest, 5.09%, decreased by 89.97% in the northern part of Jiangsu Province. The accumulated rates of mass chemotherapy were 159.00% in middle part of Jiangsu Province,103.00% in the southern part of Jiangsu Province and 105.00% in the northern part of Jiangsu Prvince.The per capita income, the use of running water and hygienic latrines increased gradually from the northern part to the southern part and there were significant differences in the 3 survey regions. Conclusion The Ascaris infection rate is influenced by mass chemotherapy, economics and health conditions in rural residents, especially the mass chemotherapy.

Objective To evaluate the impact of the project diverting the Yangtze River water to the Northern Jiangsu on transmission towards the north of Oncomelania hupensis snails, in order to provide the scientific basis for the South-North Water Diversion Project (east route). Methods The running situation of the water diversion project, the data on hydrology of the waterway and the distribution of snails and schistosomiasis were investigated with the methods of epidemiology、hydrology and field test. Results There was no significant correlation between the region of waterhead and water supply on the change of snail areas. There was no significant correlation between the snail areas of the region of water supply and the volume of water diversion, either. The snail habitat was stable at the Gaoyou segment along the Grand Canal. The snail habitat in the natural place of the north of 33?15′ north latitude on the east route has not been discovered yet. Conclusion There is no sign of transmission towards north on the snail habitat at the Gaoyou segment along the Grand Canal since the project was constructed in 1961. There is no evidence that the project leads to the spread of snails and schistosomiasis, either.

Objective To detect the impact of Diltiazem on the major adverse cardiac events (MACE) in six months after percutaneous coronary intervention (PCI).Methods A total of 192 patients after PCI with coronary atherosclerotic heart disease were enrolled in this study.The patients were randomly divided into Diltiazem therapy group (101 patients) and non-Diltiazem therapy group (91 patients).The high-sensitivity C-reactive protein (hs-CRP) was assessed before and 24 h after PCI,and the incidence of Major adverse cardiovascular events(MACEs) were assessed at the sixth month after PCI.Results Compared with before PCI,hs-CRP level increased significantly in both group after PCI (P＜0.01),but hs-CRP level was lower in Diltiazem therapy group than in non-Diltiazem therapy group (P＜0.05).Compared with non-Diltiazem therapy group,there was lower incidence of MACEs during six months follow-up in Diltiazem therapy group.Conclusions Diltiazem can decrease the incidence of MACEs during six months after PCI.
