Introduced in the paper is the development and building of motor medical equipment in China,namely vehicle-mounted field hospitals,cabin hospitals,hospital ships,and rescue helicopters among others.It is pointed out that such development falls far from complete in the country,as evidenced in the poor development for airborne,and an integrated medical rescue system covering land, sea and air needs to be further enhanced in the future.

OBJECTIVE: To study the effects of Shengji Huayu Recipe (a traditional Chinese medicine compound recipe for resolving stagnation and promoting granulation) and its decomposed formulas (Huayu Recipe for resolving stagnation and Shengji Recipe for promoting granulation) on the synthesis of collagen types I and III in granulation tissue of rats in early wound healing. METHODS: Twenty-four male Sprague-Dawley (SD) rats with full-thickness skin lesion were randomized into 4 groups: Shengji Huayu Recipe-treated group, Shengji Recipe-treated group, Huayu Recipe-treated group and untreated group. Collagen types I and III in granulation tissue of the rats were tested with immunohistochemical methods and image analysis. RESULTS: On the third day of wound healing, collagen I of the rats in both Shengji Huayu Recipe-treated group and Shengji Recipe-treated group was higher than that in the untreated group, and collagen I of the rats in Huayu Recipe-treated group was lower than that in the untreated group (P<0.05). Collagen III of the rats in the three treated groups were lower than that in the untreated group (P<0.05). On the seventh day of wound healing, Collagen I of the rats in both Shengji Huayu Recipe-treated group and Shengji Recipe-treated group was higher than that in the untreated group (P<0.05), and collagen III of the rats in both Shengji Recipe-treated group and Huayu Recipe-treated group was higher than that in the untreated group (P<0.05). CONCLUSION: Resolving stagnation and promoting granulation therapy can promote the wound healing in rats.

BACKGROUND: It has been reported that magnesium sulfate(Mg2SO4)treatment has a satisfactory effect on brain ischemia-reperfusion injury, but its effect on spinal cord ischemic injury remains unclear.OBJECTIVE: To evaluate the effects of intravenous administration of Mg2SO4 on spinal cord ischemia-reperfusion injury and further probe into its mechanism.DESIGN: Randomized controlled repeatedly measuring design based on the experimental animals.SETTING: Central research laboratory of a university hospital.MATERIALS: The experiment was conducted in the Central Research Laboratory, Medical College of Xi' an Jiaotong University from April 2003 to June 2004. Twenty-seven New Zealand white rabbits with body mass of 1.9to 2. 5 kg were included. The rabbits were randomly divided into Mg2SO4group, normal saline group and sham-operation group with 9 rabbits in each group.METHODS: The lower segment of the kidney under abdominal aorta was occluded for 30 minutes and 48-hour reperfusion was performed to establish ischemia-reperfusion model of lumbosacral segment of spinal cord. Mg2SO4group (Group A, n = 9) received Mg2SO4 at the dose of 0. 25 mL/kg per hour throughout this procedure; the same volume of saline solution was used in normal saline group(Group B, n=9) . Animals of sham-operation group (Group C, n = 9) were anesthetized and received laparotomy without aortic occlusion. The somatosensory evoked potential(SEP) was detected before ischemia, 30 minutes after ischemia, and 1, 2, 8, 16 and 24 hours after reperfusion. Motor function score was assessed in Mg2SO4 and saline groups 24 and 48 hours after reperfusion. After reperfusion for 48 hours, the animals were killed and histopathological test was performed on the spinal cord.MAIN OUTCOM MEASURES: Motor function score, SEP monitoring and spinal histopathological test.RESULTS: The latency of SEP(Nt) was markedly longer 30 minutes after ischemia in Mg2SO4 group. It was obviously recovered during the first two hours after reperfusion compared with during ischemia, but was obviously prolonged after that. Waveform disappeared 30 minutes after ischemia in normal saline group. SEP amplitudes and latencies in sham-operation group did not change remarkably during the procedures and all the animals recovered without neurological deficits. At each reperfusion time point, the recovery of SEP(N1) latency was better in Group A than that in Group B( P ＜ 0.05). The average motor function score at 24 hours and 48 hours after reperfusion was significantly higher in Group A[ (3.7 ±0.5) and(3.4 ±0.7) points] than that in GroupB [(3.0±0.7) and (2.6±0.9) points](P ＜0.05). The normal nerve cell counting of spinal cord 48 hours after reperfusion in Mg2SO4 group(23. 4 ± 3. 4) was significantly higher than that in saline group (12.3 ±3.2)(P ＜ 0.01).CONCLUSION: Intravenous Mg2SO4 administration may reduce spinal cord injury and preserve neurological function in transient spinal cord ischemia in rabbits.

BACKGROUND:As a conventional internal fixation method, anatomic plate has some shortcomings. Recently locking plate has been widely used in treatment of Pilon fracture. How to effective reconstruct articular facet at the distal tibia and to reduce soft tissue damage have attracted increasing attentions. OBJECTIVE:To compare the curative effect of locking compression plate versus anatomic plate internal fixation in treatment of Pilon fracture. METHODS:A retrospective analysis was performed among 72 patients of Ruedi-Al gower II and III Pilon fracture, who were selected from Sanshui People’s Hospital of Foshan between January 2010 and August 2014. The involved patients were randomly divided into two groups:36 patients of observation group were treated with locking compression plate internal fixation, and 36 patients of control group were given anatomic plate internal fixation. The average operation time, postoperative recovery time, postoperative complications, curative effect and postoperative fracture situation were compared between the two groups. RESULTS AND CONCLUSION:The average operation time and the average postoperative recovery time of observation group were significantly better than that of control group (P<0.05). In terms of postoperative complications, there were less cases of delayed healing and non-union in the observation group than in the control group. 26 cases of observation group and 22 cases of control group recovered wel after internal fixation, observation group was better than control group. There was no significant difference in the radiological evaluation results of postoperative recovery between the two groups (P>0.05). Compared with the anatomic plate internal fixation, locking compression plate internal fixation can shorten the operation time and postoperative recovery time, reduce the incidence of delayed healing and nonunion after internal fixation, and improve clinical curative effect in treatment of Pilon fracture.
