The doctor-patient relationship is always the focus in the society. The relationship seems more complex and sensitive in the pediatric surgical ward because its patients are kids. However, the pediatric surgical residents' ability of doctor-patient communication is lack of systemic and norma-tive training, which is not good for the mutual understanding between doctors and patients. This study explores how to enhance the residents' doctor-patient communication skills from the perspective of awareness, professional knowledge and some specific skills. In the meantime, it discusses the need to train the teachers and set up a regular examination-assessment system.

AIM: To study the effect of oligonucleotides containing unmethylated CpG motif (CpG ODN) on mouse bone marrow-derived dendritic cells (BMDCs) in anti-HcaF cytotoxicity. METHODS: BMDCs were stimulated by CpG ODN in combination with tumor antigen (TAg). The expression of CD80 on BMDC surface was analyzed by FCAS. Level of IL-12 (p70) in supernatants of BMDC culture was detected by ELISA. The proliferation of T cells was examined by MTT assay. Cytotoxicity of CTL induced by CpG ODN combining with TAg was detected by MTT assay. RESULTS: CpG ODN combining or not combining with TAg up-regulated the expression of CD80 on BMDC surface and stimulated BMDCs to produce a high level of IL-12. CpG ODN-activated BMDC promoted the proliferation of T cells. CTL induced by CpG ODN in combination with TAg appeared strong specific cytotoxicity on Hca-F cells. CONCLUSION: CpG ODN may effectively induce the functional maturation of mouse BMDC in vitro. CpG ODN in combination with TAg can enhance the anti-HcaF cytotoxicity of CTL. [

Objective: To investigate the factors that affect the outcome of pregnancies complicated with critically heart disease admitted to obstetric Intensive Care Unit (ICU). Methods: A retrospective study was conducted for 188 pregnant and postpartum patientscomplicated with heart disease who were admitted to the ICU in West China Second University Hospital from July 2009 to March 2013. Results: During the 4 years, there were 619 cases of pregnancy complicated with heart disease hospitalization. Among them, 188 (30.37%) patients complicated with severe heart disease were admitted to the ICU, accounting for 39.17% of the total ICU admission (480); the mean maternal age was (28.45±6.08) years old and the mean gestational time was (36.03±4.19) weeks. 23 (12.23%) patients received regular antenatal care in our hospital. 61 (32.45%) patients never received antenatal care before hospitalization. Among them, 5 patients were dead. hTe ratio for diagnosis of heart disease before pregnancy, during pregnancy and atfer admission were 39.89%, 25.54% and 34.57%, respectively; the most common heart diseases during pregnancy were congenital cardiac disease (80, 42.55%) and rheumatic heart disease (45, 23.94%) followed by arrhythmias (20, 10.64%). The most common complication were pulmonary arterial hypertension (51, 27.13%), arrhythmias (47, 25.00%) and severe heart failure (30, 15.96%); the cardiac function of 164 (87.23%) patients was at stage I–II and 5 (2.66% ) patients died when discharged from hospital. 151 (80.32%) patients received multidisciplinary consultation and 34 (18.09%) used central venous catheterization to control central venous pressure (CVP). 21 (11.17%) patients required mechanical ventilation. 11 (5.85%) patients required emergency life support (cardiopulmonary resuscitation 9 + electric deifbrillation 3). Conclusion: Pregnancy complicated with heart disease is the leading reason for admission to ICU. hTe congenital cardiac disease, rheumatic heart disease and arrhythmias are the main heart diseases during pregnancy. Multidisciplinary cooperation and intensive care are the key measures to improve the outcomes of patients with critically illness. It is very important for reduction of the maternal mortality rate through strengthening preconception care and antenatal care.

Objective To evaluate the anti-tumor activity of interferon ? with different structures including pegylated interferon ?-1b (PEG IFN ?-1b), pegylated interferon ?-2b (PEG IFN ?-2b) and natural interferon ? (IFN ?) in male BALB/C nude mice with human renal adencarcinoma (ACHN) tumor. Methods Athymic BALB/C nude mice were received a subcutaneous injection of ACHN cells (2?106/0.2ml) on the rear flank. After four weeks, the size of tumor reached a mean volume of 50-100 mm3, and the interferon was administrated. The mice with tumor were divided into four groups, and were administrated with placebo (0.2ml/mouse thrice weekly), IFN ?-1b (50?g/mouse thrice weekly), PEG IFN ?-1b (150?g/mouse once weekly) and PEG IFN?-2b (150?g/mouse once every week), respectively, for five weeks. The tumor volumes were measured weekly prior to treatments until the end of the fifth week. All mice in each group were sacrificed to measure the weight of the residual tumor. The anti-tumor activity of IFN ? in vivo was evaluated by studying their ability to reduce the volume and weight of tumor. Results IFN ? may significantly reduce the volume and weight of ACHN tumor in mice. The average tumor weight was 0.422g in placebo group, while 0.263g, 0.235g and 0.219g in the groups treated with PEG IFN ?-1b, IFN ?-1b and PEG IFN ?-2b, respectively. No significant difference was found among the three groups treated with IFN ?. Moreover, the volume of tumor in three groups treated with IFN ? was significant reduced than that in placebo group. Conclusion IFN ? with different structures have showed the similar ability of ACHN tumor suppression at the dosage of 150?g per week.

Objective To prove the application of bilingual teaching in the child health care curriculum. MethodsEnglish dubbing and Chinese subtitling DVD coursewares of child growth and development were played to medical interns.The interns were asked to do questionnaires to examine feasibility and effectiveness. Results In 8-year program medical students,77.8% of them and 64.8% of the 5-year nutrition professional students could understand the contents of more than 90%.If there was no Chinese subtitles,the ratio were only 5.6% and 6.4%.Most students preferred English subtitles and dubbing,and endorsed the model of bilingual teaching. Conclusion DVD coursewares with Chinese subtitles and English dubbing can be widely used in the teaching of child health care.

AIM: To evaluate the effect of staphylococcal enterotoxin B (SEB) or staphylococcal enterotoxin C (SEC) combining with dendritic cells (DC) on T cell functions and in vitro anti-HcaF tumor cytotoxicity of activated T cells. METHODS: S-100 protein expression in DC was detected by immune histochemistry staining. The expressions of I-E~? and CD80 molecules on DC, the expression of CD69 molecule on T cells and the production of IL-2 and TNF-? by T cells were determined with flow cytometry. The proliferation of T cells and its cytotoxicity to HcaF tumor cells were detected by MTT assay. RESULTS: In vitro experiments showed that isolated DC expressed high level of S-100 protein. SEB or SEC-induced DC highly expressed I-E~? and CD80 molecules and that SEB or SEC-induced DC promoted the activation and proliferation of T cells. 100 ?g/L of SEB or SEC was the most effective concentrations to induce T cells to secret IL-2 and TNF-?. The T cells activated by SEB or SEC combined with DC showed significant cytotoxicity to HcaF cells, appearing a stronger role than tumor antigen combined with DC. There was no difference in the role for T lymphocytes between both SEB and SEC. CONCLUSIONS: The results indicate that SEB or SEC combined with DC is an effective way to enhance T cell functions, producing stronger cytotoxicity to HcaF tumor cells than tumor antigen-loaded DC used at present, which offers a forceful evidence for the possibility of superantigen SEB or SEC combining with DC to be applied to clinical tumor immunotherapy.

Statement of the REporting of studies conducted using routinely collected data (RECORD) and evaluating checklist of good research for comparative effectiveness (GRACE) were translated and introduced in this paper. The two evaluation tools would help researchers of Chinese medicine to conduct real world study in future. RECORD statement focus on unique aspects of studies conducted with routinely collected health data and the perceived need for better reporting of methodological issues. Researchers of comparative effectiveness research could refer to GRACE checklist. It was believed that researchers of Chinese medicines who were keen on real world studies would be benefited from the two tools.
