Objective To investigate the effectiveness of interventional therapy for the atherosclerotic renal artery occlusion (ARAO). Methods During the period of June 2001-Dec. 2007, 16 patients with ARAO (total of 16 occluded arteries) underwent interventional managements, including percutaneous endovascular renal artery revascularization, balloon dilatation angioplasty and stent placement. Follow-up survey was made at regular intervals. The patent condition of the renal artery was evaluated with ultrasonography and digital subtraction angiography. The blood pressure and the renal function were determined and the data were statistically analyzed in order to assess the intermediate and long-term effect of the interventional therapy. Results Of 16 patients, technical success was achieved in 15 (93.8%) and failure occurred in one. During a follow-up period of 9 - 24 months, 3 patients died. According to the data obtained at each patient’s last follow-up survey, the hypertension fell to normal in 3 (25.0%), was improved in 7 (58.3%) and showed no marked change in 2 patients (16.7%), with a clinical efficacy of 83.3% (10 / 12). The renal function was improved in 2 (16.7%), stabilized in 6 (50%) and deteriorated in 4 patients (33.3%), with an effective rate of 66.7% (8 / 12). Conclusion For the treatment of atherosclerotic renal artery occlusion, the interventional therapy carries high successful rate and can effectively lower the blood pressure level, in addition, it can also protect the renal function in a certain degree.

ObjectiveTo investigate the effect of cardiopulmonary bypass (CPB) on the secretory function of islet cells in rabbits.MethodsTwenty adult New Zealand white rabbits of both sexes,weighing 2.5-3.0kg,were randomly divided into 2 groups ( n =10 each):sham operation group (group S) and CPB group.The rabbits were anesthetized with 3% pentobarbital sodium 30 mg/kg.Blood samples were collected from the left femoral artery at 5 min after anesthesia (T1),immediately before CPB (T2 ),immediately after aortic clamping (T3 ),and at 5,35 and 75 min after aortic unclamping (T4-6) in the two groups for determination of levels of blood glucose,insulin and glucagons.Insulin resistance index was calculated.ResultsCompared with group S,the blood glucose concentration and levels of insulin and glucagons and insulin resistance index at T3-6 were significantly increased in group CPB ( P < 0.05).ConclusionAlthough increase in blood glucose enhances the secretion of insulin in islet β cells,hyperglycemia cannot be compensated completely by the increased insulin during CPB in rabbits.The increase in blood glucose may be related to islet α cell resistance.

Objective To evaluate the effects of Achilles tendon lengthening on talipes equinus in children with spastic cerebral palsy. Methods From December, 2013 to June, 2014, seventeen spastic cerebral palsy children with talipes equinus (34 feet) received Achilles ten-don lengthening. Ankle dorsiflexion range of motion (ROM) and surface electromyography from tibialis anterior and medial head of gastroc-nemius were measured before and 8 to 12 months after operation, respectively. ROM of passive and active dorsiflexion, root mean square (RMS) of tibia muscle group and co-contraction ratio (CR) when standing were compared. Results The ROM of ankle passive and active dorsiflexion increased (Z>4.867, P<0.001), while the RMS of gastrocnemius muscle decreased when ankle passively dorsiflex (t=4.31, P<0.001). RMS of tibialis anterior and gastrocnemius muscle changed little when standing (Z<1.291, P>0.05), while CR reduced (t=2.38, P<0.05). Conclusion Achilles tendon lengthening can improve the coordination of tibia muscle group to increase the ROM of ankle for chil-dren with talipes equinus after spastic cerebral palsy.

Scientific research output of clinical trials in Chinese medicine (CM) is insufficient, but international papers hold an important scientific position in China. Based on the current situation, we analyzed the present publication situation of international medical papers in our country, and the feasibility and urgency of publishing international papers on clinical trials of CM. Finally, we proposed to use the PDCA (plan-do-check-action) cycle method to improve the quality control and management of CM clinical trials. Moreover, by combining our experience in relevant scientific research launched at our department, we expounded strategies for improving the quantity and quality of international papers in CM.

Objective To investigate the role of mitochondrial permeability transition pore (mPTP) in attenuation of myocardial ischemia-reperfusion (I/R) injury by delayed preconditioning with sevoflurane in rats.Methods Eighty male SD rats, weighing 250-300 g, were randomly assigned into 5 groups ( n = 16 each): Ⅰsham operation group (group S), Ⅱ group I/R, Ⅲ sevoflurane delayed preconditioning group (group SP), Ⅳ the mPTP opener atractyloside + sevoflurane delayed preconditioning group (group A + SP), and Ⅴ atractyloside group (group A). Myocardial I/R was induced by ligation of anterior descending branch of left coronary artery for 30 min followed by 120 min of reperfusion in group I/R, SP, A + SP and A. In group SP and A + SP, 2.5%sevoflurane was inhaled for 1 h, while pure oxygen was inhaled for 1 h in the other groups, and then myocardial ischemia was performed 24 h later. In group A + SP and A, atractyloside 5 mg/kg was injected intravenously via caudal vein 15 min before ischemia. Blood samples were taken from carotid arteries for detection of serum cardiac troponin-Ⅰ (cTnI) concentrations at the end of reperfusion. Then the rats were sacrificed and hearts removed. The myocardial infarct size (IS) and expression of Bcl-2 and Bax in the myocardium were determined. Myocardial ultrastructure was examined with the electron microscope. Results Serum cTnI concentrations and Bax expression were significantly higher, the myocardial IS was significantly larger and Bcl-2 expression was significantly lower in the other groups than in group S ( P < 0.05). Serum cTnI concentrations and Bax expression were significantly lower, the myocardial IS was significantly smaller and Bcl-2 expression was significantly higher in group SP than in group I/R ( P < 0.05). Microscopic examination showed less damage in group SP than in group I/R. The protection provided by sevoflurane preconditioning was abolished by atractyloside. Conclusion Inhibition of mPTP opening can result in an up-regulation of Bcl-2 expression and down-regulation of Bax expression, which plays a role in attenuation of myocardial I/R injury by delayed preconditioning with sevoflurane in rats.

Objective To observe the influence of local-anaesthetic combined with dezocine on brachial plexus block and postoperative analgesia.Methods 60 patients scheduled for unilateral upper limb operation were randomly divided into two groups of C group and D group with 30 cases in each group.The brachial plexus block was performed under ultrasound guiding.Two groups received a bolus injection of local anesthetic 30ml,but the local bolus injection of D group consisted of Dezocine 10mg.The tine of sensory blocked producing effect,anesthesia effect,sensory blocked duration were observed.Two hours after sensory nerve recovered,the scores of VAS pain and Ramsay Sedation were recorded.Adverse reactions of perioperation were also observed(nausea,vomiting,dizzy,respiratory,urine retention,pruritus).Results The sensory blocked duration in D group was(7.1±1.1)h,which was significantly longer than that of C group[(4.5±0.8)h](t=10.47,P<0.01);Two hours after sensory nerve recovered,the score of VAS pain in D group was(1.7±0.7)points,and significantly lower than that of C group[(3.9±1.0)points](t=9.87,P<0.01).Both two groups had no adverse reactions.Conclusion Addition dezocine 10mg to local anesthetic solutions for interscalene brachial plexus block,it could prolong the sensory block duration,provide satisfactory postoperative analgesia,have no adverse reactions.
