1.Discussion on the path of legal education
Chinese Journal of Medical Education Research 2012;11(4):367-370
The Socialist legal construction needs to strengthen the legal education.It is significant to seek for the path of legal education in order to enhance the actual effect of legal education.The path of legal cducation includes traditional education,utilitarian education,reasonable education,legitimate education and feeling education,etc.We can get a better actual effect of legal education if different paths of legal education (traditional education,utilitarian education,reasonable education,legitimate education and feeling education) can be integrated,infiltrated and complemented.

The tumorigenesis of breast cancer is a multistep process with many factors.The microRNAs (miRNA) participates in the development and distance metastasis of tumor by regulating proliferation,apoptosis and migration of tumor cells.The study of the mechanisms that miRNA impacting breast cancer cell proliferation and metastasis may provide new ideas for the diagnosis and treatment of breast cancer.

Objective To investigate the gene polymorphism of HLA-DR locus and feature of HLA haplotypes of Han Population in Tianjin area.Methods Reverse PCR-SSOP typing results of HLA-DR alleles of 3000 cord blood units from Han population pregnant women in Tianjin area were compared to those of European Caucasian and the Han populations in Xi’an area.Results DRB1 *15, allele presented the highest frequency,followed by DRB1 *09,DRB1 *07,DRB1 *12,and DRB1 *04.The main haplotypes were A *02-DRB1 *09,A *02-DRB1 *15,B *13-DRB1 *07,A *02-DRB1 *12,A *30-DRB1 *07 and B *46-DRB1 *09 in sequence.The frequencies of DRB1 *12 and DRB1 *09 alleles were significantly higher than in European Caucasian,while the frequencies of DRB1*01 and DRB1 *03 alleles were significantly lower than those in European Caucasian.As compared with that of the Han population in Xi’an,there was not significantly difference except a decrease in frequencies of DRB1 *04 and DRB1 *13 alleles.Conclusions Distribution of the allelic polymorphism of HLA-DR locus was similar to those in northern Han population,such as in Xi’an area,and it was obviously different from those in European Caucasian.

Objective To explore the influences of indoor and outdoor sources of air pollutants on NO 2 concentra tions in indoor air.Methods The dynamic variations of NO 2 concentrations in indoor and outdoor air were continuously monitered by ML 9841B chemiluminescence continuous monitoring analyzer in2families of White haven town of west Cumbrra,UK.Results During the period of indoor air monitoring,typical background concentrations of NO 2 in air in the center of White haven were between19and28?g /m 3 (10min-mean),and rose to38-47?g /m 3 (10min-mean)during the morning and evening rush of traffic.NO 2 concentration increased about 190?g /m 3 (10min-mean)after the use of a gas cooker in the kitchen A1-hour mean concentration of253?g /m 3 was recorded in the kitchen air of one of the houses,which substantially exceeded the NAQS standard of200?g /m 3 .Conclusion The increase of NO 2 concentration in kitchen air induced by the use of gas appliances played a more important role in influencing the indoor air quality than outdoor air did.

Oxidative damage theory is currently one of the predominant theories on the mechanisms of aging. Previous research has shown that antioxidants can extend the lifespan in the model organism by scavenging free radicals,inducing the expression of stress related genes and hormesis. However, recent studies have suggested that these pharmaceuticals may cause serious side effects,such as promoting oxidation,increasing the risk of cancer,and destroying the metabolic balance. The low absorption and targeting property also limit the efficiency of most antioxidants. As a result ,the correlation between antioxidants and lifespan extension remains to be demonstrated. We reviewed the research progress in the field of lifespan extension by antioxidants in recent years and provided references for future research in related areas.

Objective To compare the operation effect of esophageal foreign body removal with transparent cap-assisted endoscopic technique and traditional method. Methods Ninety-six patients with foreign body incarcerated in esophageal were randomly divided into two groups, and they were underwent transparent cap-assisted endoscopic esophageal foreign body removal or traditional endoscopic esophageal foreign body removal respectively. The clinical data of the two groups were collected, and the success rate, the operation time, the endoscopic vision clarity and the complication rate of the two groups were all recorded and analyzed. Results The success rate in transparent cap-assisted endoscopic technique group was 100% compared with 95.83% in traditional method group, and two cases of failure were transferred to transparent cap-assisted endoscopic technique and finally succeed. The mean operation time were (8.58±3.21) min in transparent cap-assisted endoscopic technique group, and (10.64 ± 5.45) min in traditional method group, and there was no significant difference in two groups (P > 0.05). Forty-five cases got A level and three got B in transparent cap-assisted endoscopic technique group in endoscopic vision clarity, in contrast to 35 A, 11 B and two C in traditional method group. The difference between the two groups was statistically significant (P = 0.020). There was no case with serious complications such as bleeding, perforation or death in two groups. Conclusions Transparent cap-assisted endoscopic technique for body removal is safety and efficacy, and this technique can provide better endoscopic operation field of vision and help improve the success rate of esophageal foreign body removal.

Objective To observe polyclonal antibodies immobilized on magnetic submicron particles (MSP) as affinity adsorbents and test the reliability of predicted maximum adsorption activity of an enzyme/mutant from a cell lysate (Vs) in recognizing positive mutants.Methods Escherichia coli alkaline phosphatase (ECAP) and Pseudomonas Aeruginosa arylsulfatase (PAAS) were purified by affinity chromatography to serve as immunogens for the preparation of their antisera, which after fractionation by 33% ammonium sulfate and DEAE-cellulose chromatography yielded the respective polyclonal antibodies.After activation of COOH on MSP, polyclonal antibodies of each enzyme were immobilized to give MSP-polyAb.Activities of an adsorbed enzyme were measured with a chromogenic substrate of 4-nitrphenol by determining absorbance at 405nm after the termination of reaction by alkali.Based on the response curve of activities of the adsorbed enzyme to protein quantities of a lysate, Vs was predicted for comparison.Results The maximum adsorption quantity of ECAP or PAAS on the respective MSP-polyAb was about 2.0mg/g.Specific activity of ECAP after affinity purification was about 70-fold of that of PAAS.ECAP mutant R168K showing about 50% activity improvement versus ECAP was recognized by comparison of Vs predicted with only 2.5μg of MSP-polyAb;with PAAS mutant G138S as the starting one, the use of 10.0μg of MSP-polyAb to predict Vs recognized the mutants bearing more than 20% activity improvement.Conclusion With an optimized quantity of MSP-polyAb to predict Vs, weak positive mutants of an enzyme of low activity can be recognized when activities of the adsorbed enzyme/mutant are reliably measured.

ObjectiveTo investigate the therapeutic effect of narrow band ultraviolet B ( NB VUB)and its influence on the expression of IL23/Th17 axis in peripheral blood of patients with Psoriasis vulgaris,and to further explore the mechanism of action of NB UVB.MethodsForty - eight cases of Psoriasis vulgaris were treated with NB-UVB irradiation for 20 times,the therapeutic effect was evaluated by the Psoriasis Area and Severity Index (PASI) scores.Peripheral blood was obtained from normal healthy controls and patients with Psoriasis vulgaris before and after NB-UVB irradiation.Three color flow cytometry was carried out to quantify Thl7 cells,and ELISA was used to examine the levels of serum IL17 and IL23.Results The mean PASI scores were significantly decreased after treatment with NB UVB irradiation[ (8.12±4.05)score vs (3.98±2.03) score,P<0.01 ].Levels of Th17[ (2.78 ± 1.93)% vs (0.98±0.56)% ],IL-17[ (23.85±7.98) pg/ml vs (6.53±4.26) pg/ml] and IL-23 [ (29.73 ± 12.08)pg/ml vs ( 16.73±8.91 )pg/ml] were significantly higher in patients with Psoriasis vulgaris than that in healthy controls ( P <0.01 ).After treatment with NB-UVB irradiation,levels of Th17 [ ( 1.13 ± 0.51 ) % ],IL-17 [ ( 8.03±5.01 )pg/ml ],and IL-23 [ ( 17.03 ± 9.85 )pg/ml ] were significantly decreased than before ( P < 0.01 ),and were positively correlated with PASI ( P <0.05).ConclusionsNB-UVB may affect IL23/IL17 to achieve its therapeutic effect on patients with Psoriasis vulgaris.
