Objective To investigate the expression of extracellular matrix metalloproteinase inducer (EMMPRIN) in pancreatic cancer and its relationship with P-glycoprotein (P-gp) and vascular endothelial growth factor (VEGF),and to study its correlation with invasion,metastasis and drug re- sistance.Methods The expressions of EMMPRIN,P-gp and VEGF in 34 cases of pancreatic cancer were detected by immunohistochemistry.The correlation analysis and Chi squared test were been used by SPSS 10.0.Results The positive rates of EMMPRIN,P-gp and VEGF in pancreatic cancer were 61.8%,55.9% and 64.7% respectively.EMMPRIN,P-gp and VEGF were associated with lymph node metastasis (P＜0.05),but not associated with sex,age,size of tumor and degree of differentia- tion (P＞0.05).There were close relationship between EMMPR1N and P-gp,VEGF respectively (r= 0.398,r=0.432,P＜0.05).Conclusions EMMPRIN,P-gp and VEGF were higher expressed in pancreatic cancer.EMMPRIN express was correlated with both P-gp and VEGF.It has indicated that during the progression of pancreatic cancer,there are close relationship between invasion,metastasis and drug resistance,and EMMPRIN may play key role in this process.

Objective To investigate the significance of plasma D-dimer in systemic lupus erythematosus (SLE) with secondary antiphospholipid syndrome(APS). Methods The levels of plasma D-dimer in 104 SLE patients and 50 normal individuals were measured by immunoturbidimetry. Results The level of D-dimer in SLE was obvious higher than that in normal individuals(t=5.172,P0.05). Conclusion The level of plasma D-dimer in patients with SLE rised obviously. Its rise was associated with disease activity and secondary APS in SLE.

Objective : To investigate the prevalence of dyslipidemia among overweight and obese primary and middle school students in Tongzhou District, so as to provide the evidence for the implementation of comprehensive health education and early interventions for overweight and obese students. Methods : The basic information, physical examinations and blood lipid testing results were collected from the primary and middle school students in Tongzhou District from 2015 to 2019 through the nutrition and health monitoring project among students in Tongzhou District. The epidemiological characteristics of overweight and obese students with dyslipidemia were descriptively analyzed. Results : Among the 1 483 primary and middle school students detected, the overall prevalence rates of overweight, obesity and dyslipidemia were 12.68% ( 188 students ), 20.43% ( 303 students ) and 20.57% ( 305 students ), respectively. The prevalence of dyslipidemia was higher in overweight and obese students ( 24.44% ) than in students with normal weight ( 18.65%, P<0.05 ), and the prevalence of dyslipidemia was higher in male overweight and obese students than in female overweight and obese students (29.00% vs. 18.92%, P<0.05), while higher prevalence of dyslipidemia was seen in middle school students than in primary school students ( 37.72% vs. 20.32%, P<0.05 ). In addition, the prevalence of dyslipidemia was higher in students with daily exercise of less than a hour than in students with daily exercise of a hour or longer ( 27.88% vs. 18.44%, P<0.05 ). Conclusions The prevalence of dyslipidemia is high among overweight and obese primary and middle school students in Tongzhou District. Health educations should be reinforced to male, middle school students with daily exercise of less than a hour.

For screening the potential drugs as anti-liver fibrosis candidates, we established a high- throughput drug screening cell model based on COL1A1 promoter. The activity of COL1A1 promoter and luciferase reporter gene can be elevated by TGF-β1, and inhibited by candidate drugs. We constructed a recombined plasmid with COL1A1 promoter and luciferase reporter gene pGL4.17, the activity of COL1A1 promoter was reflected by fluorescence intensity. COL1A1 promoter activity was detected by Dual-Luciferase Reporter Assay System, it came that the relative luciferase activity of COL1A1 promoter was 15.98 times higher than that of control group induced by TGF-β1, showing the recombined plasmid could be used in cell model. The recombined plasmid was transfected into human hepatic stellate cells LX2, detected the effect of potential drugs, and obtained a stable expression system through stable transfection and monoclonal cell culture. A sample which could reduce COL1A1 promoter activity signally by our cell model, decreased collagen I mRNA and protein expression detected by real-time RT-PCR and Western blotting. It indicates this novel cell model can be used in high-throughput drug screening of potential anti-liver fibrosis drugs.

Objective Postictal language testing can provide useful diagnostic information for seizure lateralization.However no such a study based on non-English language was done previously.We investigated the latency of language recovery in Chinese patients with temporal lobe epilepsy (TLE).Methods Complex partial seizures in patients with TLE were extracted from our video-electroencephalogram (EEG) database.For all patients,consciousness testing started as soon as seizures were detected.When they were alert and cooperative,they were asked to read out a sentence “昨晚他们听到老在电台里讲话”which was printed on a card.When the patients were able to read the sentence correctly,the language function was considered recovered.Results Totally 65 complex partial seizures from 22 cases of TLE (11 left and 11 right) were included.Patients were cooperative to language testing in 54 seizures (83％).The latency for consciousness recovery (CRL) and latency for consciousness language recovery (LRL) were not associated with seizure duration,but the seizure lateralization.The CRL (median,161 s) and LRL (281 s) in the left TLE were statistically significantly longer than that in the right TLE (30 s,54 s respectively).Using 150 s recovery time as bound language recovery ratio was 87％ (27/31) in right TLE and 13％ (3/23) in left TLE.Conclusion Postictal language testing based on ideographic Chinese words helps to establish seizure lateralization in patients with TLE.

The sequences of ITS, matK, rbcL and psbA-trnH of 9 Gynostemma species or variety including 38 samples were compared and analyzed by molecular phylogeny method. Hemsleya macrosperma was designated as outgroup. The MP and NJ phylogenetic tree of Gynostemma was built based on ITS sequence, the results of PAUP phylogenetic analysis showed the following results: (1) The eight individuals of G. pentaphyllum var. pentaphyllum were not supported as monophyletic in the strict consensus trees and NJ trees. (2) It is suspected whether G. longipes and G. laxum should be classified as the independent species. (3)The classification of subgenus units of Gynostemma plants is supported.

Aim of the present study is to investigate activation effect of nobiletin on cystic fibrosis transmembrane conductance regulator (CFTR) chloride channel activity. CFTR-mediated iodide influx assay and patch-clamp tests were done on FRT cells stably co-transfected with human CFTR and EYFP/H148Q. Nobiletin potently activated CFTR chloride channel activity in a dose- and time-dependent manner. The CFTR blocker CFTR(inh)-172 could completely reverse the effect. Preliminary mechanism study indicated that nobiletin activated CFTR chloride channel through a direct binding way. In addition, ex vivo tests done on mice trachea showed that nobiletin time-dependently stimulated submucosal gland fluid secretion. Nobiletin may be a therapeutic lead compound in treating CFTR-related diseases including disseminated bronchiectasis.

Data were analyzed from self-filled questionnaires for the students who took the elective course of general practice in China Medical University. 95.5% of students thought it was necessary to study general practice in the college. 0-10 was used to score the degree of how they want to choose general practice as a career, the median was 0 before they had the class and the median was 5 after the class (Wilcoxon rank test, P<0.01). But there were still some places need to be improved in terms of curriculum design, teaching methods and community practice. The General Practice teaching need to be innovated and the teaching mode should be different from the traditional one.
