Objective To observe the effect of thymalfasin on non-operative treatment of cervical cancer.Methods Seventy-eight patients with advanced cervical cancer were divided into two groups according to the digital table,each group in 39 cases.The two groups were treated with concurrent chemoradiotherapy.The observation group was given 1.6 mg of thymalfasin subcutaneously each Monday to Friday.While the control group received no additional treatment.And then the two groups were compared in terms of curative effects,adverse reactions,immune states and cellular immune functions.Results The results showed that the differences of curative effects[there were 23 patients in the control group,as compared with 31 patients in the observation group,achieved a complete response(CR),x2=3.852,P<0.05],adverse reactions(grade Ⅲ or Ⅳ radiation-induced enteritis occurred in 4 patients in the observation group,and 12 patients in the control group,x2=5.032,P<0.05;Grade Ⅲ or Ⅳ leukopenia occurred in 16 patients in the observation group,and 25 patients in the control group,x2=4.165,P<0.05;Grade Ⅲ or Ⅳ nausea,vomit occurred in 6 patients in the observation group,and 14 patients in the control group,x2=4.303,P<0.05),immune states and cellular immune functions between the two groups were significant[the counts of CD+3(t=9.236,P<0.05),CD+4(t=7.445,P<0.05),CD+4/CD+8(t=7.445,P<0.05) and NK(t=9.256,P<0.05)]were significantly higher in the observation group after treatment.Conclusion In the treatment of advanced cervical cancer,concurrent chemoradiotherapy combined with thymalfasin can improve the curative effect,reduce the side effects,improve the quality of life and enhance the immunity.

Objective To understand the current situation of medical postgraduates'!honesty edu-cation, find the weak point and explore new ways of the honesty education. Methods The honesty educa-tion survey questionnaire was designed and conducted to the postgraduates of Grade 2014 in Peking University Health Science Center. The research contents included the basic information of postgraduates, honesty cognition, clean and self-discipline, honesty education, the recommendation of honesty education and the application of honesty education carrier. 1 038 questionnaires of a total of 1 142 questionnaires were recovered and the recovery rate was 90.9%. EPIData3.0 software was used for double entry and database establishment, and SPSS 19.0 software for statistical treatment. Results 82.3% (854) of the postgraduates recognized the work of clean government, but only 62.1% (644) of the postgraduates concerned about it. 78.3% (813) of the postgraduates expressed hatred for the dishonest behavior and hoped to eliminate it. 77.6%(806) postgraduates often paid attention to honest education content which was pushed by the new media. 16.5% (171) postgraduates thought that the new media was very important to the honest cognition. Conclusions We should pay more attention to medical postgraduates'!honesty education, find its weak points according to the investigation and make full use of the network and new media. And at the same time we should combine the actual environment to establish a hierarchy of honesty education system, and carry out honesty education through total environment which contains the school administrators, instructors/head teachers and tutors.

BACKGROUND: Streptococcus mutans (S. mutans) is generally considered to be the principal aetiological agent for dental caries, thrS gene may relate to the virulence of S. mutans involved in the adherence, acidogenicity and acidodurance.OBJECTIVE: To investigate the conservation status of the thrS gene of S. mutans and to construct the homologous recombinant plasmid.METHODS: Southern Blot was used to analyze the distdbuUon of thrS gene in S. mutans. The upstream and downstream sequences of thrS gene were cloned respectively into multiple cloning sites of suicide plasmid pFW5 to construct the recombinant plasmid,RESULTS AND CONCLUSION: The thrS gene was conserved in 6 strains of S. mutans in this test. By PCR analysis and enzyme digesting, it was confirmed that S. mutans thrS gene homologous recombinant plasmid was successfully constructed,which can be used in future research of construction of thrS -negative mutans of S. mutans strain UA159.

Interleukin-6(IL-6)is associated with cancer staging, survival, apoptosis and the sensitivity to chemotherapeutic drugs, and it is overexpressed in the cancer tissue and serum of cancer patient.IL-6 Can regulate proliferation and differentiation of cancer cells through IL-6/STAT3 signaling pathway. Therefore, blocking IL-6/STAT3 signaling pathway has potential therapeutic implications for cancer.

Objective: To compare the phenotype of induced dendritic cell (DC) derived from peripheral blood of the healthy individuals and the patients with oral carcinoma. Methods:15 patients with oral carcinomal at stages II or above were assigned to study group and 15 cases of healthy volunteers were assigned to control group. Leukocyte were isolated by density centrifugation. Adherent fractions were incubated in present of GM-CSF,IL-4 and TNF-? for 7 days in vitro. The morphological change of the cultured cells was observed by light microscopy and electronic microscopy. The phenotype expressions of CD83,CD1a,CD86, CD80, HLA-DR were analysized by flow cytometry. Results:Typical DCs were obtained from two groups after 7 days culture. The expression rate of CD83,CD1a on DC from healthy volunteers was significantly higher than that from patients (P0.05). Conclusion:DC derived from oral cancer patient' s peripheral blood monocyte might be more matured and is a good cell model for further immunotherapy and research.

Background Neovascular diseases such as retinopathy of prematurity often leads to irreversible vision loss.The study on oxidative damage mechanism is becoming more and more important.Whether brain derived neurotrophic factor (BNDF) has protection to retinal ganglion cells(RGCs) has few research reports.Objective The study was to investigate the expression changes of BDNFin mouse retinas of oxygen-induced retinopathy (OIR).Methods Thirty SPF C57BL/6J immature rats were divided into OIR group and normal control group and to fifteen rats for each group.OIR models were established by raising 7-day-old (P7) mice together with maternal mouse in (75±3) ％ oxygen environment for 5 days and then returned to the normal air environment,and the mice of the normal control group were raised in the normal air environment.The P17 mice were sacrificed for retinal histopathological examination by hematoxylin and eosin staining, and the number of vascular endothelial cell nucleus extending the inner limiting membrane was counted.Whole retinal mounts were prepared after fluorescein isothiacyanate-dextran (FITC-dextran) (9 ml/kg) was retrosorbitally injected,and the distribution of retinal vessels was observed in P17 mice.The relative expression levels of BNDF in retinas were detected in P13, P15, P17 mice, and the results were compared between the normal control group and the OIR group.Results Histopathological examination showed that retinal inner limiting membrane was smooth in the normal control group, but a lots of vascular endothelial cell nucleus extending the inner limiting membrane were seen under the optical microscope in the OIR group.The number of the vascular endothelial cell nucleus extending the inner limiting membrane was 1.70±0.68 in the normal group and 45.3±3.13 in the OIR group, showing significant difference between them (t =86.5, P =0.00).Whole retinal mount revealed that normal retinal vessels and network-like capillaries were exhibited in the mice in the normal group, while tortuous vessels,capillary loss and non-perfusion areas were revealed in the OIR group on the whole retina mounts.The relative expressing levels of BDNF in retinas were 263.992±9.451 and 218.432±9.710 in P15 and P17 mice in the OIR group,which were significantly higher than 230.324±7.779 and 115.846±7.305 in the normal control group (t=14.2,42.3 ,P＜0.05).Conclusions OIR can be inhibited by increasing the expression of BNDF.

Objective To identify the influencing factors for pediatric nursese' reporting of adverse events at 3A hospitals in Beijing. Methods Adopting the random sampling of ten 3A hospitals with pediatric wards in Beijing and conducting an questionnaire survey of some nurses in those hospitals. Results The possibility of adverse events reporting increased with the awareness of adverse events which was related with their severity. Except for title, educational background, length of service, position and past experiences were not associated with the barriers. The major perceived barrier was fear of colleague relationship brokenup and some other undesirable consequence. Conclusions Better training of awareness of adverse events and changes of the punitive culture by the roots as well as some regulation or policy were the major solutions to improve incident reporting.

Many genetic events have been described to be involved in the development of tumor,but a lot of recent researches proved that epigenic events also played an important role in it.DNA methylation is one of the common modification of epigenic events,the binding of methyl-CpG binding domain proteins has been shown to lead to transcriptional repression of many tumor repressor genes.
