This study was aimed to compare and investigate protective effects of metformin and rosiglitazone on cardiac dysfunction in experimental diabetic cardiomyopathy (DC) model rats. The experimental DC rat model was induced by feeding high calorie diet plus single intraperitoneal injection of small dosage of streptozotocin (STZ). Then, intragastric administration of metformin (140 mg·kg-1) or rosiglitazone(2 mg·kg-1) was given to DC rats for consecutive 6 weeks. Parameters of general signs, eating amount, blood sugar, blood lipids, heart function, heart structure and lipometabolism of myocardial tissues were measured. The results showed that both metformin and rosiglitazone can obviously improve the myocardial injury of DC model rats and reduce the CK value (P < 0.01). Metformin can obviously increase the cardiac output of DC model rats (P < 0.01). Rosiglitazone can improve the maximum rate of myocardial contraction and diastole of the model rat's left ventricle (P < 0.05). Both metformin and rosiglitazone can decrease interventricular septal thickness (IST) value (P < 0.01). Metformin can obviously im-prove general signs of DC rats, inhibit body weight loss and reduce water intake (P < 0.05). Metformin can obvi-ously reduce the blood sugar level (FBG, GSP, HbA1c and FMN) of DC rats (P < 0.05, or P < 0.01) as well as the concentration of TG (P < 0.01). Rosiglitazone can reduce the concentration of FBG and HbA1c (P < 0.05). Meanwhile, rosiglitazone can significantly reduce the concentration of TG and LDL as well as obviously increase the myocardial FA-β-oxidase (P < 0.05). It was concluded that both metformin and rosiglitazone can recover the cardiac dysfunction and myocardial injury of DC rats on certain level. Metformin showed more effects on eating amount and body weight improvements of DC rats.

This study was aimed to observe the influence of Catalpol on real-time gait analysis of early recovery after permanent middle cerebral artery occlusion (pMCAO) in rats to evaluate its effect on the improvement after cerebral ischemia. Rats were randomly divided into 6 groups, which were the normal control group, model group, Tianbaoning group, Catalpol 15, 30, 60 mg·kg-1 group. Rats were trained on the gait instrument for 7 days before pMCAO, 3 times/day. After the training, pMCAO model was made. And continuous infusion was performed from the 3rd to the 14th day after the operation. Then, the real-time gait behavior was detected on the 14th day. The re-sults showed that 14 days after the surgery, compared with the normal control group, the models had a significant extending in the duty cycle (P < 0.01), and obvious increasing of the average body angle of absolute value (P <0.05), the shortening of the two feet supporting time (P < 0.05), and extending of three feet supporting time (P <0.01), and increasing of the coordination index (P < 0.01). Compared with the model group, the Catalpol of 30 mg·kg-1 and 60 mg·kg-1 group has obviously decreased duty cycle and average body angle of absolute value (P <0.05, or P < 0.01). The Catalpol of 30 mg·kg-1 can obviously reduce the coordination index of the right front foot relative to the other three feet (P < 0.05), which improved the coordination of cerebral ischemia animals. It was concluded that Catalpol can improve the real-time gait behavior changes of cerebral ischemia model rats. There-fore, Catalpol have a neural protective effect on cerebral ischemia.

Objective To investigate the effects of different doses of ulinastatin on severe thermal injuryinduced myocardial damage in rats. Methods One hundred and eighty female SD rats weighing 180-220 g were usedin this study. Thirty percent of the total body surface (TBS) was shaved chemically with 20% sodium sulphate and then exposed to 92 ℃ water for 18 s. The animals with third degree thermal injury involving 30% of the TBS were randomly divided into 3 groups (n = 60 each): group Ⅰ thermal injury (group TI); group Ⅱ and Ⅲ received intraperitoneal ulinastatin 40 000 and 80 000 U/kg respectively immediately after thermal injury (group U1 , U2). The TI group received equal volume of normal saline IP instead of ulinastatin. Blood samples were taken from abdominal aorta before (baseline) and at 1, 3, 6, 12 h after thermal injury for determination of serum concentrations of cTnI, IL-1β, IL-6, IL-10 and TNF-α (10 samples at each time points). Ten animals were sacrificed at each time point after blood sampling. The myocardial specimens were obtained for microscopic examination and measurement of MDA content and SOD activity. Results Compared with group TI, the serum concentrations of cTnI, IL-1β, IL-6 and TNF-α and MDA content in myocardium were significantly decreased and the myocardial SOD activity was significantly increased in group U1 , while in group U2 the senum concentrations of cTnI, IL-Iβ, IL-6 and TNF-α and myocardial MDA content were significantly increased and the myocardial SOD activity was significantly decreased. There was no siginificant difference in the serum concentrations of IL-10 among the three groups. Microscopic examination showed that myocardial damage was accentuated in group U2 as compared with group U1. Conclusion Ulinastatin 40 000 U/kg can ameliorate severe thermal injury-induced myocardial injury through inhibition of inflammatory response and lipid peroxidation response, whereas ulinastatin 80 000 U/kg accentuates myocardial damage.

ObjectiveTo evaluate the curative effect of reconstruction of the hand and foot defects with bones and tendons exposure using free medial sural artery perforator flap(MSAP). MethodsRadiographs of 2 cadavers injected with a modified lead oxide-gelatin mixture were digitally analyzed. Between April 2007 and December 2010, thirty-four patients with soft tissue defects in the distal limb were treated with the free MSAP flap transplantation. The sizes of the defect ranged 6 cm × 4 cm-13 cm × 8 cm, and the flaps ranged 7 cm× 5 cm-14 cm × 9 cm. These clinical cases included 25 hands and 9 feet, all of them with bones and tendons exposure.In these defects,twenty-two were clean,twelve got infections.In our cases, twenty-three flaps were nourished with single perforator vessel and else 11 with two;perforator vessel fifteen flaps were dissected one superficial vein to anastomose with that of the recipient sites in addition to accompanying vein anastomosis;The sensation of 9 flaps recovered the hands were reconstructed with cutaneous nerve anastomosis. ResultsA partition of the calf skin blood vessels,and three-dimensional reconstruction image of the sural artery were obtained.All flaps survived,five of them appeared partially violet and bubbles. Followed up 6-21 months, the cosmetic results were satisfactory and without apparent bulkiness.The flap colors were similar to recipient sites. The flap senses reconstructed with neural anastomosis recover to S2-S3. ConclusionThe new flap is very suitable to repair the soft tissue defect in the distal limbs,because the fairly constant perforator vessel,the reliable blood supply and the cosmetic shape of the MSAP flap are all advantages of it in addition to no damage to low leg chief artery and gastrocnemius.
