Objective This paper explored the effect of the early clinical exposure in im-proving medical students' cognitive aspects of the doctor-patient relationship. Methods (1)From 280 undergraduate students of Grade 2010 who participated in early clinical exposure of Xi'an Jiaotong University College of Medicine and 280 undergraduate students of Grade 2011 who did not participate in the early clinical exposure, we selected 140 students respectively to conduct a simple random sam-pling survey. The results were analyzed by SPSS after using Microsoft Excellsoftware for entry. Statis-tical methods selected χ2-test/Fisher exact test(P<0.05). (2)We had an interview to students,teachers leading the project, instructor,experts engaging in the study of the doctor-patient relationship by using focus group discussion and in-depth interview, and then using thematic analysis to analyze the data. (3)The main aspects of questionnaires and interviews were: details, activity participation/interest, general cognitive on the doctor-patient relationship, passion for profession, choice of career, the effect in improving medical students' cognitive aspects of the doctor-patient relationship and the suggestions and comments. Results The effective questionnaires collected from Grade 2010 were 134, and124 from Grade 2011.The participation rate of the undergraduates of Grade 2010(participating group) was 94.0%(126/134), while the interest rate of undergraduates of Grade 2011 (control group) was only 76.6%(95/124). Participating group had a better cognitive understanding of doctor-patient relationship than control group(P=0.0192). The activities had significant effects on choice of career(P=0.0002), and no effect on passion for profession(P=0.7372). There was statistically significant difference on their views of employment(P=0.0002). The key words for the interview were: not enough preparation before activity, not reasonable timing, teachers leading the project, stimulation of professional pride. Conclusions Early clinical exposure activities can be effective in improving medical students' awareness of the current doctor-patient relationship. Still we have some shortages in the activity, some more exploration and amelioration should be made in late stage.

Background:
The testis has been reported to be a naturally O 2 -deprived organ, dimethyloxaloylglycine (DMOG) can inhibit hypoxia inducible factor-1alpha (HIF-1α) subject to degradation under normal oxygen condition in cells.
Objectives:
The objective of this study is to detect the effects of DMOG on the proliferation and differentiation of spermatogonial stem cells (SSCs) in Bama minipigs.
Methods:
Gradient concentrations of DMOG were added into the culture medium, HIF-1αprotein in SSCs was detected by western blot analysis, the relative transcription levels of the SSC-specific genes were analyzed using quantitative reverse transcription polymerase chain reaction (qRT-PCR). Six days post-induction, the genes related to spermatogenesis were detected by qRT-PCR, and the DNA content was determined by flow cytometry.
Results:
Results revealed that the levels of HIF-1α protein increased in SSCs with the DMOG treatment in a dose-dependent manner. The relative transcription levels of SSCspecific genes were significantly upregulated (p < 0.05) by activating HIF-1α expression. The induction results showed that DMOG significantly increased (p < 0.05) the spermatogenesis capability of SSCs, and the populations of haploid cells significantly increased (p < 0.05) in DMOG-treated SSCs when compared to those in DMOG-untreated SSCs.
Conclusion
We demonstrate that DMOG can promote the spermatogenesis activity of SSCs.

Objective To investigate the effect of depression symptoms on surgical outcome of posterior decompression among cervical spondylotic myelopathy (CSM) patients. Methods Between October 2006 and October 2011 in our hospital, lami?nectomy or laminoplasty was performed in 396 cases that were enrolled in the study. There were 132 males and 264 females with an average age of 60.2 years(ranged,39-84 years). All patients were divided into depression group and non?depressed group by the 21?item Beck Depression Inventory (BDI). There were no statistically significant differences between groups in age, sex, smok?ing status, duration of symptoms, and employment status (whether in the current working). The Japanese Orthopedic Association (JOA) scores, Neck disability index (NDI) and visual analogue scale (VAS) were compared after 1.5 months postoperatively. Re?sults All of 396 cases were followed up. The mean follow up duration was 32 months (range,24-50 months). There were no statistically significant differences in the CCI decline (7.1%±2.1% versus 6.8%±1.5%), expansion degree[(130.9±7.0) mm2 versus (150.8 ± 5.2) mm2] and the drift?back distance of the spinal cord [(5.7 ± 1.2) mm versus (6.2 ± 0.8) mm]. However, pa?tients with continuous depression showed poorer improvement than non?depressed patients in the surgery outcome: JOA im?proved (1.42±0.56 versus 6.76±3.12); NDI declined (7.31±2.18 versus 21.11±11.36); and VAS lightened (16.08±19.76 versus 23.85±20.79). Conclusion Depression contributed a dissatisfied surgery outcome after posterior decompression on functional re?covery, disability index and pain scores among patients of the cervical spondylotic myelopathy.

OBJECTIVE: Ambulance personnel who witness trauma experienced by patients have been reported to experience positive changes, known as vicarious posttraumatic growth (VPTG). We examined VPTG and its relationship with social support and resilience among ambulance personnel. METHODS: The sample (n=227) was recruited from six emergency centers in China. The measures included the Posttraumatic Growth Inventory (PTGI), the Social Support Rating Scale (SSRS), and the 10-item Connor-Davidson Resilience Scale (CD-RISC-10). Structure Equation Modeling (SEM) and the bootstrapping procedure were used to examine indirect effects. RESULTS: The participants' mean score for VPTG was 68.96 (SD=15.51). Social support had significant direct effects on resilience (β=0.51, p < 0.001) and VPTG (β=0.25, p=0.001), and resilience (β=0.58, p < 0.001) had a significant direct effect on VPTG. Furthermore, social support had a significant indirect effect (0.51×0.58=0.30, p < 0.001) on VPTG through resilience. CONCLUSION: Although the nature of the work of ambulance personnel is not expected to change, the negative effects of the trauma they encounter can be reduced by providing them with more support resources and interventions to foster their resilience, which in turn, promote VPTG.
