Through the investigation on medical students' understanding of hospice care and their cognition and attitudes on voluntary services in hospices in Wenzhou,this paperconcluded that medical students accepted hospice care highly but knew little about it,and medical students were willing to participate in hospice care but actually rarely attended it.It is also suggested that universities should strengthen the propaganda and education of hospice care and volunteer service,joint efforts should also be given to expand the service opportunities and channels,and trainings should be provided to improve the development of hospice care volunteer services among medical students.

Objective To investigate the clinical efficacy of warm needling plus palm pressing spine reduction technique in treating postpartum thoracic facet joint disorder.Methods Forty patients with postpartum thoracic facet joint disorder were randomly allocated to treatment and control groups, 20 cases each. The treatment group received warm needling plus palm pressing spine reduction technique and the control group, warm needling alone. The numeric pain rating scale (NPRS) score, the Oswestry Disability Index (ODI) score and the Quality of Life Scale score were recorded in the two groups before and after treatment and the clinical therapeutic effects were compared between the two groups.Results The total efficacy rate was 95.0% in the treatment group and 75.0% in the control group; there was a statistically significant difference between the two groups (P<0.01). There were statistically significant pre-/post-treatment differences in the NPRS score and the ODI score in the treatment group (P<0.01). There was a statistically significant pre-/post-treatment difference in the NPRS score in the control group (P<0.01). There were statistically significant post-treatment differences in the NPRS score and the ODI score between the treatment and control groups (P<0.01,P<0.05). There were statistically significant pre-/post-treatment differences in the SF-36 PF, RP, BP, VT, SF and MH scores in the treatment group (P<0.01,P<0.05). There were statistically significant pre-/post-treatment differences in the SF-36 PF BP, SF and MH scores in the control group (P<0.01,P<0.05).Conclusion Warm needling plus palm pressing spine reduction technique is an effective way to treat postpartum thoracic facet joint disorder.

Objective To analyze the present situation of technical efficiency in TCM hospitals throughout the country, discuss the influencing factors causing inefficiency and propose corresponding suggestions. Methods The technical efficiency in 60 TCM hospitals in the country was analyzed using the stochastic frontier cost model for panel data and the influencing factors causing inefficiency were discussed using the multiple stepwise regression method. Results The average technical inefficiency was 22.59% and inefficiency showed an upward trend as the areas shifted from the eastern through the middle to the western regions. Five factors, including the utility rate of beds and the proportion of health technicians among the entire hospital staff, were statistically significant so far as the effect on the increase of the overall cost was concerned. Conclusion The stochastic frontier cost model for panel data is the best method for evaluating the technical efficiency in TCM hospitals. On the basis of the above analysis, suggestions for strengthening scientific management, improving the utility rate of resources and reducing unnecessary waste are put forward.

Objectives To explore the effects and mechanism of acupuncture treatment in emergent of acute hypertension by studying the acupuncture treatment on acute hypertension rats. Method The acute hypertension rat model was made by injecting adrenalin into the abdomen. After probing specific points, NO, ET-1, angiotensin and rennin levels were tested. Results Acupunctured for 30 minutes, the experimental group's diastolic pressure dropped and NO level rose, and these changes were statistically significant regarding those of the medicine control group. After the acupuncture treatment, the rennin level of the medicine control group and the experimental group were statistically different with the control group, but no significant difference was found between the medicine control group and the experimental group. Conclusion Probing Quechi, Taichong, Sanyinjiao and Neiguan may lead to the improved performance of the vessel endoderm, the rise of NO level and the decrease of angiotensin content, and consequently reduce the blood pressure of acute hypertension rats.

BACKGROUND: Studies have confirmed that nerve growth factor can promote wound tissue to release al kinds of endogenous growth factors and growth factor receptors, which play a positive regulatory role. The nerve growth factor can promote cel proliferation and accelerate wound healing, thus making the wound healing developed from the passive waiting healing to active control healing. OBJECTIVE: To investigate the effects of local application of nerve growth factor on the expressions of transforming growth factor β1 and basic fibroblast growth factor in rat burn wounds. METHODS: Twenty-four adult Sprague Dawley rats were used in the study, and Ⅱ degree deep burn wound was made on the back of rats. Then, these rats were randomly divided into four groups. After burn wound debridement, the wounds were covered with gauzes containing 1, 2.5 and 5 μg/mL nerve growth factor solution and normal saline respectively. At 3, 5, 9 and 14 days after treatment, the wound healing time and percentage of residual wound were observed. Then, wound tissues were cut for histological examination, in order to detect the expressions of transforming growth factor β1 and basic fibroblast growth factor in wounds, as wel as the cel ular DNA cycle. RESULTS AND CONCLUSION: The wound healing time in the treatment groups was shorter than that in the control group, especial y in 5 ug/mL nerve growth factor treatment group (P < 0.01), and the percentage of residual wound in the treatment groups was less than that in the control group. The histological examination showed the number of nucleated cells in the superficial dermis of the treatment groups was significant increased when compared with that in the control group; the expressions of transforming growth factor β1 and basic fibroblast growth factor in the treatment groups at different time points were stronger than those in the control group, and the expressions at 5 and 9 days were stronger than those at 3 and 14 days; percentage of cells in S phase of the treatment groups was significantly increased, especial y in 5 mg/L nerve growth factor group (P < 0.01). The results indicate that local application of nerve growth factor can accelerate wound healing by increasing the expressions of transforming growth factor β1 and basic fibroblast growth factor, stimulating mitosis and promoting proliferation.

Objective To analyse the factors influencing the death of patients with aortic dissection (Stanford type A arota dissection) who underwent urgent surgery.Methods The clinical data of 197 patients with aortic dissection (Stanford type A arota dissection) treated with urgent surgery from the First Affiliate Hosiptal of Xinjiang Medical University were retrospectively analyzed between January 2009 and June 2015 in order to determine the factors influencing the early-mortality.Results Of them,23 patietns dead.In univariant analysis,the rate of mortality was 11.68％.The following factors at admission were independetly associated with early-mortality:hypertension,coronary atherosclerotic heart disease,LVEF ≤ 50％,time consumed for CPB ≥ 180 min,time required for cross-clamping aorta ≥ 120 min,Cr ≥ 130 μmol/L,rethoracotomy for hemostasis (P ＜0.05).The preoperative renal failure (Cr≥130 μmol/L) and time consumed for cross-clamping aorta ≥ 120 min were strongly associated with the early-mortality based on the logistic regression analyses.Conclusions The risk of aortic dissection surgery is very high,and it is mondatory to carefully evaluate the patient' s general condition and the indications during peroperative period,and to take active measures to shorten the time of clamping aorta and total operation time in order to reduce the risk of operation and increase the survival rate of patients.
