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 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 study the influence of dietary restriction on the expression of insulin signaling pathway genes in mouse adipose tissue. Method:Twenty four C57BL/6 male mice of 2 w age were subjected to either AL (ad libitum) or DR (dietary restriction, 40% from AL) randomly until sacrificed.Then the epididymis fat pads were weighed, and their insulin signaling gene expression was detected by Oligo Insulin Signaling Pathway Microarray (SuperArray), and two of the differentially expressed genes, NPY and AKT3 were validated by Real Time PCR. Results:Dietary restriction significantly reduced the weight of epididymis fat pads and 31 (20 up, 11 down regulation) of 96 insulin signaling pathway genes were differentially expressed. The results of Microarray coincided with that of Real Time PCR. Conclusion:The differential regulation on the expressions of insulin signaling pathway gene may be the important molecular basis of dietary restriction.

The contents and features of medical imaging technology and medical image processing course are introduced in this paper,relationship of the two courses and their different parts are mainly discussed.Contents and the multimedia courseware are then designed.

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.

Objective To explore the relationship between subclinical hypothyroidism(SCH)and microvascular complications(diabetic nephrop-athy and diabetic retinopathy)in type 2 diabetic patients. Methods According to the condition of complicating with SCH,157 patients with type 2 diabetes were divided into SCH group(40 cases)and the euthyroid group(117 cases). The age,sex,duration of diabetes,smoking status,blood pressure,body mass index(BMI),glycosylated hemoglobin(HbA1c),blood lipid,renal function,thyroid function,urine albumin/urine creatinine, and fundus examination were analyzed and compared between the two groups. The relationship between SCH and microvascular complications in type 2 diabetic patients was explored. Results There was no significant difference of age,sex,duration of diabetes,smoking,blood pressure,BMI, HbA1c,blood lipid,or serum creatinine between the two groups. The incidence of diabetic retinopathy in SCH group was significantly higher than those in euthyriod group(32.5%vs 14.5%,P=0.044);however there was no difference in the incidence of diabetic nephropathy. After adjustment for potential confounding factors(age,sex,duration,blood pressure,BMI,HbA1c,diabetic nephropathy)by multivariate logistic regression analy-sis,SCH was still the risk factor of diabetic retinopathy(OR=2.210,95%CI 1.512-4.117,P=0.032)in type 2 diabetic patients. Conclusion SCH could be a risk factor of diabetic retinopathy in type 2 diabetic patients,and there was no significant effect on diabetic nephropathy.

Drawing on recently published foreign literature, this paper comprehensively analyses the research status of medical tourism from the concept of decision-making factors and risks for tourists, as well as the impacts of medical tourism. For future research, it proposes a greater focus on medical tourists, caregiver-companions and medi-cal tourism facilitators. To promote the development of Chinese medical tourism, a development model must be con-structed, international medical services, consummate policies, and regulations must be in place, and medical tourism personnel must be trained and welcomed.
