Objective To explore the effect of lysolecithin choline (LPC) on blood-brain barrier(BBB) permeability in rats with acute pancreatitis. Methods Acute pancreatitis rat model was produced and rats were randomly divided into:(1)Test group-AP, rats received LPC by tail vein injection; (2)control group I, AP rats were given normal saline by tail vein injection; (3)control group II, sham operation without AP, but LPC was given by tail vein injection.Horseradish peroxidase(HRP) was used as a tracer to determine BBB permeability 7~10 days later.Results The test group showed local extravascular effusion of HRP, indicating that BBB permeability was markedly increased,while both control groups showed no apparent increase of BBB permeability,which were statistically significant(P

Objective: to examine the relationship between emotional states and skin conductance response during lie- detection and to provide evidence for improvement of lie- detection technique. Methods: 38 university students participat- ed in the study. They were provided with antisocial behavior materials that elicited different levels of emotional arousal. Results: Significant difference in skin conductance response was observed with the high emotionality items eliciting the highest skin conductance response. Conclusion: Under a certain level of pressure, individuals’emotional state has direct impact on skin conductance. High emotionality questions are better for detecting lies and honesty than low emotionality questions. In addition to lying, the questions themselves have direct impact on subjects’emotional responses, which in turn lead to skin conductance response. When cues for emotionality are obvious, related events tend to receive greater at- tention by subjects and thus lead to special skin conductance response.

Objective To discuss the methods of specification and quantification of thinking process of syndrome differentiation and treatment of old and famous TCM practitioners; To inherit the clinical experience and ideas of TCM practitioners more effectively. Methods Based on one typical case of Professor Lv Renhe treating chronic nephritis, indexing the prescriptions with TCM Subject Headings thesaurus and analyzing them with “Chinese medicine prescription intelligence analysis system” (“CPIAS” for short), relative dose, comprehensive property, comprehensive taste, comprehensive channel tropism, and prescription efficacy were under quantitative analysis. Results The typical case included two prescriptions of initial diagnosis and six diagnosis. CPIAS quantitative analysis showed that relative dose, comprehensive property, comprehensive taste, comprehensive channel tropism, and prescription efficacy were in accordance with syndrome differentiation and treatment of Professor Lv Renhe for chronic nephritis. Conclusion This method has guiding significance for studying and inheriting the speculative regularities and academic thoughts of Professor Lv Renhe.

Objective To summarize the treatment of 10 aortic coarctation cases ,who receive the surgery from ascending aorta to thoracic descending aorta with the prosthetic graft, discuss the valuable and appliable of this method. Methods Cardiac surgery, Chinese Acdemy of Medical Sciences, Peking Union Medical College Hospital department treated 10 patients who got the aortic coarctation from Jan. 2006 to Dec. 2015 Seven male patients and 3 cases of female patients consist of the sample, aged from 14 to 35 years old, the median age was 27. One cases consolidated aortic valve deformity and aortic root expansion, the others were simple aortic coarctation. Their upper limbs blood pressure was 20 mmHg higher compared with the low limb. Meanwhile, there was no sign of surgery contraindication. Ten cases received this operation under cardiopulmonary bypass situation. And the patient who consolidate aortic valve deformity and aortic root expansion receive the Bentall surgery at the same time. Results There was no death during perioperative time, no spinal cord ischemic and other serious complications. Those patients went back to outpatient department after discharging from hospital 3 to 6 months. The differential pressure between upperlimbs and low limbs were less than 20 mmHg, and the CTA results indicated no aneurysms. Conclusion Using artificial blood vessels to make a graft from the ascending aorta to the descending aorta is an effective method for treatment of thoracic aorta.

BACKGROUNDTo investigate the expression level and its clinical significance of the multi-drug resistance (MDR) associated protein in lung cancer specimens.

METHODSThe expression levels of Pgp, MRP, GST-π and TopoII of MDR associated protein were detected in 60 lung cancer samples and 30 paracancerous tissues by S-P immunohistochemistry method.

RESULTSThe positive rate of Pgp, MRP, GST-π and Topo II in the lung cancer tissues was 40.0% (24/60), 61.7% (37/60), 45.0% (27/60) and 81.7% (49/60) respectively, which was significantly higher than those in paracancerous tissues (P < 0.01). No significant correlation was observed among the expression of multi-drug resistance-related protein and TNM staging, pathological type, cell differention and lymph node metastasis status (P > 0.05).

CONCLUSIONSLung cancer has overexpression of multi-drug resistant-related genes during the oncogenesis. Combined detection of these genes may be useful for guiding the lung cancer chemotherapy.

Objective: To analyze the sero-epidemiological characteristics of hepatitis B virus among people born during 1994-2001, conducted by the national hepatitis B sero-epidemiological surveys in 2006 and 2014. Methods: Based on the data of the two national hepatitis B sero-epidemiological surveys in 2006 and 2014, people born during 1994-2001 were included into our analysis as this study subjects. The two surveys were conducted in 160 disease surveillance points of 31 provinces (not including Hong Kong, Macao and Taiwan) in China. Face-to-face interviews with the subject by door to door or on the investigation site were conducted by trained staff using standard questionnaires to obtain basic information including birth date, sex, ethnicity, resident place and so on. And then 5 ml venous blood was collected. Enzyme-linked immunosorbent assay (ELISA) reagents were used for HBsAg, anti-HBs and anti-HBc measurements and Abbott micro-particle enzyme immunoassay (MEIA) reagents was used to confirm test. We analyzed HBsAg, anti-HBs and anti-HBc positive rate by gender, ethnicity, urban/rural, eastern/central/western region, birth years and compared the distribution of serum epidemiological characteristics in 2006 and 2014.
