Objective To explore the effectiveness of short-term integrated intervention to reduce discrimination against people living with HIV/AIDS(PLWHA)among medical students.Methods A quasi-experimental survey was conducted.Two medical schools in Beijing,one as intervention group and the other as control group were selected by convenience sampling,from which 123 undergraduate students or interns of medical and nursing specialties were recruited,62 in the intervention group and 61 in the control group.The intervention group was provided with 13 hour long antidiscrimination intervention by increasing HIV/AIDS related knowledge,sympathy and skill in dealing with people living with HIV/AIDS,while the control group was deprived of any intervention.The attitude of the students in the 2 groups were assessed by questionnaire survey in 5 time points after the intervention.Results Compared with the control group,at 4 time points after the intervention students in the intervention group had less discrimination against PLWHA in general;and significantly less discrimination in dealing with them as patients(P

Objective To investigate the effect of rapamycin(RPM)on hepatic interleukin-10(IL-10)gene and acute liver injury in rats with postburn Staphylococcus aureus sepsis.Methods Fifty male Wistar rats were randomly divided into four groups:normal control group,scald control group,postburn sepsis group,and RPM treatment group.Tissue samples from liver and plasma were collected to determine IL-10 mRNA and protein expressions,and liver function parameters were also measured.Results Compared to postburn Staphylococcus aureus sepsis group,in RPM treatment group hepatic IL-10 mRNA expression and plasma IL-10 were significantly increased at 0.5 hour after RPM treatment(P

Objective To analysis the effect of compound betamethasone injection combined with radiation on keloid in frontal facial region. Methods 60 cases of keloid patients in zhejiangprovincial people's hospital from January 2014 to January 2016 were selected,all patients were treated with surgery,the patients were randomly divided into observation group and control group,30 cases in each group,radiotherapy was used in the control group,the observation group was treated with local injection of compound betamethasone on the basis of the control group,the therapeutic effects, pain scores, adverse reactions and complications were compared between the two groups. Results The recurrence rate of the observation group was 3.33% which was significantly lower than that of the control group 10%,the improvement rate of the observation group 93.33% was significantly higher than the control group 80%,the difference was statistically significant (P<0.05).one,two and three months after operation,the pain scores in the observation group were significantly lower than those in the control group at the same time point,the difference was statistically significant (P<0.05).The adverse reaction rate was 6.66% (2/30) in the observation group and 23.33% (7/30) in the control group, there was no significant difference between the two groups.The incidences of skin sag, pigmentation, incision delayed union and telangiectasia in the observation group were significantly lower than those in the control group (P<0.05). Conclusion Compound betamethasone injection combined with radiation on the frontal facial keloid patients with significant effect,can significantly reduce the recurrence rate,improve the rate of improvement,reduce pain and complications in patients.

Objective To investigate the correlation between pathogens and spectrum of disease in infants with human cytomegalovirus(HCMV) active infection.Methods A total of 378 cases of HCMV infection diagnosed by the identification of HCMV IgM or PP65 antigen of HCMV.HCMV gB genotyping was carried out by nested PCR and restriction fragment length polymorphism(RFLP) in 107 cases.The results of pathogen,spectrum of disease and clinic feature were analyzed.Results In all 378 infant patients with HCMV,27.78% were systemic infection and 72.22% involved just single organ.Hepatitis,HCMV inclusion disease,thrombocytopenic purpura,pneumonia were pre- dominant with 33.07%,27.78%,13.49%,6.35% respectively.The rate of HCMV inclusion dis ease in infants younger than 2 weeks was higher than in those aged from 3 12 weeks(P ~ 0.05) and children older than 12 weeks(P＜0.01).Infants with higher rate of PP65 antigen positive cells were apt to systemic infection than those with lower rate of PP65 positive cells(P＜0.01).Infants,who were positive by detections of all three methods,were apt to systemic infection than others(P＜0.01). Moreover,infants positive of IgM and PP65 antigen were apt to systemic infection than those just positive by one of the two methods(P＜0.01).The result of gB genotype analysis in 107 cases showed 53 cases of gBⅠ,20 of gBⅡ.18 of gBⅢ.7 of gBⅠ+gBⅡ,5 of gBⅠ+gBⅢand 4 of gBⅡ+gBⅢ,and gBⅣwas not found.Conclusion HCMV could infect multiple organs and have some different clinic features.Combination of different methods can increase the sensitivity to detect the pathogen.The gBⅠgenotype is most prevalent in these infants.

Availability of appropriate drugs for children has been a bottleneck both at home and abroad for years.As a result, drugs for adults that are market available emerge a choice of convenience for children's treatment instead.For unique physiological and psychological characteristics of children, these drugs must be dispensed on individual basis before usage to children in question.Such drugs play a key role in children's treatment, and incur many problems on the other hand in their use and practice, such as drug stability, dosage accuracy, potential risks, as well as legitimacy in drug dispensing and use.A safe, reasonable and normalized use of such drugs calls for an orchestrated effort among pharmacists, trade associations and drug regulators as well.

The ultimate goal of post-genome research is to understand a complete set of proteins in a living organism for their expression pattern and biological function,which is called proteomics.One of the major challenges in proteome research is to study the protein-protein interactions,and the emerging bioinformatics approaches present us tremendous advantages when dealing with protein interaction networking and data analysis.Useful bioinformatics tools include protein-protein interaction network mapping,topology of the network,structure of the module and comparison of the network.The technology advancement in this field brings further understandings to the structure and function of cells at the proteome level,which may eventually lead to the discovery of new drug targets and design methods.This paper attempts to review the current researches on protein-protein interaction with an emphasis on bioinformatics intervention,and also summarizes some widely used methods for network analysis.

AIM: To determine the ultimate preservation time of murine cardiac grafts in 4℃ Ringer's solution. METHODS: Murine cardiac grafts were implanted to the abdominal vessels heterotopically 2, 4, 6, 8 and 10 hours after cold preservation. Graft survival rate and histological morphological changes, as well as the neutrilphil, T cell, macrophage infiltration, ICAM expression were determined by immunohistochemistry. RESULTS: The cardiac function-recovery rate and 1-week graft survival rate were 100% and 83.3% in 6-hour preservation group. Compared with non-preservation control group, no more apparent histological damages, cell infiltration and ICAM expression were found. CONCLUSION: The ultimate preservation time of murine cardiac graft in 4℃ Ringer's solution was 6 hours. [

To study the quantitative structure-activity relationship (QSAR) between the stuctures of 29 flavonoids and the inhibitory activity of their multidrug resistance-associated protein (MRP) 1 and 2 by using the comparative molecular similarity index analysis (CoMSIA). By studying the impact of the combination of different molecular force fields, researchers obtained the molecular force fields that played an important role in inhibiting the activity of MRP1 and MRP2, built the optimized QSAR model, and discussed the structural modification method for flavonoids' multidrug resistance-associated protein inhibitor. The results of the study could not only provide the guidance for new drug R&D, but also help partially discuss the synergy mechanism between MRP1 and MRP2 receptors and traditional Chinese medicines containing flavonoids.
