Objectives:To investigate the effect and mechanism of adventitia applied slow-releasing triptolide on proliferation and apoptosis of VSMCs of the autologous vein graft. Methods:Twenty-four healthy rabbits were made external jugular vein to common carotid artery models and then were divided into 3 equal groups at random:Blank-control group received no management on adventitia of the vein graft;F-127 pluronic gel control group received local application of 0.5 ml 20% F-127 pluronic gel containing 0.1ml DMSO on adventitia;and experimental group received local application of 0.5 ml F-127 pluronic gel containing triptolide 300?g on adventitia. Vein graft samples were harvested at 2 weeks after the operation. Histomorphologic methods were used to detect the degree of intima hyperplasia of the samples. The expressions of proliferating cell nuclear antigen(PCNA) and bcl-2 of the samples were detected by immunohistochemistry. The apoptosis of vascular smooth muscle cells(VSMC) was detected by TUNEL. Results:Two weeks after vein grafting, compared with blank-control group and F-127 control group,intima hyperplasia was markedly inhibited by applying triptolide 300?g on adventitia(P

Objective To give a systematic reviews on effect of taking blood gas via cephalic artery for infants.Methods Meta-analysis were used to analyze literatures about taking blood gas via cephalic artery for infants.Results 11 studies were included.The rate of successful puncture was 87.5％～98.0％ in the intervention group and 55.3％ ～94.6％ in the control group.The rate of successful puncture via cephalic artery were higher.Conclusions Effect of taking blood gas via cephalic artery for infant was better than that via other artery.Successful rate was high,while the incidence rate of local side effects was low.

Objective To prevent data transfer or loss in application development when dealing with data exchange between Oracle database with different server's character set.Methods Environment variable is set to update Oracle client's character set so as to solve data transfer or loss caused by character set transformation.Results It was the environment variable not the register list that was reset,so Oracle databases with different server's character set were not connected at the same time.Conclusion An adaptive method for different server's character set is given to solve this problem.

Objective To study the clinical effect of psychological intervention combined with oral administration of aminoglucose hydrochloride capsules combined with intra-articular injection of sodium hyaluronate combined with functional exercise in the treatment of knee osteoarthritis.Methods Forty-eight patients with knee osteoarthritis were randomLy divided into control group and study group(n=39).The patients were randomLy divided into control group and study group.The control group was given intraperitoneal injection of sodium hyaluronate combined with functional exercise, the study group on the basis of the control group to give psychological intervention and oral administration of aminoglucose capsules combined therapy.Comparison of two groups of Lysholm knee function score and postoperative efficacy.Results The scores of Lysholm knee function were significantly improved after treatment, but the improvement rate of the study group was significantly better than that of the control group (P<0.05).The clinical effect of the study group was significantly better than that of the control group(94.87% vs 43.59%).The difference was statistically significant (P<0.05).Conclusion The combination of psychological intervention combined with oral administration of aminoglucose capsules with intraperitoneal injection of sodium hyaluronate combined with functional exercise in the treatment of knee osteoarthritis can significantly improve the clinical efficacy, improve the knee function and improve the prognosis, worthy of clinical application and promotion.

Objective To explore the clinical effect of calcium and calcium combined with psychological intervention on elderly patients with osteoporosis and pain.Methods The control group was given routine drug treatment (Miacalcic+Caltrate D), the study group of osteoporosis pain in patients with psychological intervention in the conventional miacacic+Caltrate D treatment on the basis of records of two groups of VAS, SDS, SAS, SF-36 scale score changes (before and after treatment).Results After treatment, two groups of SF-36 scale scores were significantly increased than before, while the VAS scale was significantly lower than before, the quality of life of the study group the degree of pain, improve the effect of better (P<0.05);the research group after treatment SDS, SAS score than before the decline than the control group (P<0.05).Conclusion The application of calcium dense combined with psychological intervention in the treatment of elderly patients with osteoporosis pain is beneficial to achieve more satisfactory pain relief effect, and significantly alleviate the corresponding negative emotions.

Network theory is applied to the optimization study on field medical equipment allocation with patient flow and its rate in wartime analyzed. With the application of queuing theory and linear programming, different optimized combinations of evacuation tools are studied, and then static model and dynamic model are established. A calculating table on queue length, service intensity and service desk is put forward to realize rapid evaluation of quantities of required field medical equipment for PLA. Some suggestions are provided to modify the current standard of PLA's basic medical equipment.

Objective To discuss the pattern of pre-hospital and in-hospital first aid of craniocerebral injury. Methods A retrospective study was carried out on 4 311 cases with craniocerebral injuries, who were directly sent into the emergency room of the department of neurosurgery, classified and cured by special doctors according to corresponding procedures. Results A total of 2 992 mildly and mediumly injured cases were cured. In 1 319 severely injured cases, 164 died within 24 hours and the other 1 155 were evaluated by GOS, showing that 750 got good recovery plus moderate disability (64.94%), 132 resulted in severe disability (11.43%), 44 in vegetation (3.81%) and 229 died (19.83%). The total fatality rate was 29.80%. Conclusions It is beneficial to cure of the severe craniocerebral injury by utilizing the following ways, ie, pre-hospital care, immediate sending into the wards, special diagnosis according to first aid procedures, operation and ICU.

Objective To investigate the inhibitory effect of appling slow-releasing triptolide on adventitia on the intima hyperplasia of autologous vein graft.Methods In 24 male New Zealand rabbits, external jugular vein to common carotid artery models were established, and then were divided into 3 equal groups at random: blank-control group, receiving no management on adventitia of the vein graft; F-127 control group, receiving local application of 0.5 mL of 20 % F-127 on adventitia of the vein graft; experiment group, receiving local application of 0.5 mL of 20 % F-127 containing triptolide 300?g. Vein graft specimens were harvested at 2 weeks after the operation. Histomorphologic methods were used to detect the degree of intima hyperplasia of the specimens. The expression of bcl-2 and Fas of the specimens was detected by immunohistochemistry. The apoptosis vascular smooth muscle cells (VSMC) were detected by TUNEL.Results Two weeks after vein grafting, compared to blank-control group and F-127 control group, intima hyperplasia of experiment group [intima thickness (29.9?7.6)?m, I/M 0.56?0.08] was markedly inhibited (P
