  • Protective Effects of Aescin on Rat Liver in Acute Pancreatitis

    【Abstract】Objective To study the liver injury and effects of aescin on liver in rats with acute pancreatitis. Methods The rats were divided into 3 groups (control group, AP group and aescin group). The serum alanine aminotransferase (ALT), serum lactate dehydrogenase (LDH), hepatic cellular energy charge (EC) and adenosine triphosphate (ATP) were detected. The pathologic changes in pancreas and liver were also observed. Results The serum levels of ALT and LDH in aescin group were significantly lower than those of the AP group. The EC and ATP levels were significantly higher in aescin group than that of the AP group. Conclusion Introvenous injection of aescin can alleviate the liver injury in rats with acute pancreatitis.

  • ARTHROSCOPICALLY ASSISTED TREATMENT OF ACUTE TIBIAL INSERTION AVULSION FRACTURE OF POSTERIOR CRUCIATE LIGAMENT VIA POSTEROMEDIAL INCISION

    Objective To investigate the effectiveness of arthroscopically assisted treatment of acute tibial insertion avulsion fracture of the posterior cruciate ligament (PCL) via posteromedial incision. Methods Between January 2010 and January 2012, 22 patients with acute tibial insertion avulsion of the PCL underwent arthroscopic reduction and fixation via posteromedial incision. There were 14 males and 8 females with an average age of 32 years (range, 18-48 years). The injury causes included traffic accident injury in 14 cases, sport injury in 4 cases, and falling injury in 4 cases. The disease duration ranged from 7 to 16 days (mean, 10 days). Of 22 patient, 14 had simple PCL injury, 6 had PCL injury with meniscus injury, and 2 with cartilage injury. The results of posterior drawer test were positive in all patients. The preoperative Lysholm score was 51.1 ± 3.4. Results All incisions healed by first intention without infection, deep venous thrombosis of lower limbs, or vessel and nerve injuries. All patients were followed up 12-24 months (mean, 18.4 months). X-ray films showed that all fractures healed with the healing time of 2-4 months (mean, 3 months). The Lysholm score was improved to 96.0 ± 2.2 at 6 months after operation, showing significant difference when compared with preoperative score (t=43.020, P=0.000). Conclusion Arthroscopically assisted treatment of acute tibial insertion avulsion fracture of the PCL via posteromedial incision is a safe, easy, and effective method.

  • MULTI-SPOT SUTURE FIXATION UNDER ARTHROSCOPE FOR TREATING TIBIAL INTERCONDYLAR ANTERIOR EMINENCE FRACTURE

    Objective To explore the surgical method and effectiveness of multi-spot suture fixation under arthroscope in treating tibial intercondylar anterior eminence fracture. Methods Between February 2006 and January 2010, 15 patients with tibial intercondylar anterior eminence fracture were treated with multi-spot suture fixation under arthroscope after fracture reduction. There were 14 males and 1 female with a median age of 33 years (range, 7-55 years). The injury causeswere traffic accident in 9 cases, sport in 2 cases, and fall ing in 4 cases. The anterior drawer test, Lachman test, and pivot shift test in all the cases turned out to be positive. The Lysholm score was 64.7 ± 1.3. According to Meyers-McKeever classification, 5 cases were classified as type II, 7 cases as type III, and 3 cases as type IV. Of them, 13 cases had fresh fracture and 2 cases had old fracture. Assisted with anterior cruciate l igament-aimer, bone tunnels (2 mm in diameter) were built through the fracture fragments after fracture reduction, through which Ethibond 2 polyester sutures were guided into the joint by No.18 spine needles; after knot of 2 sutures or knot of only 1 suture was made, the other ends of sutures were fastened together outside the joint. Results The incisions of all the cases healed by first intention with no compl ication of infection or deep venous thrombosis. Fifteen patients were followed up 14-48 months with an average of 24.2 months. The X-ray examination indicated fractures healed in all the cases at 2-4 months (mean, 3 months). At 6 months after operation, 14 cases showed negative results of Lachman test and anterior drawer test but 1 case positive, while all the cases showed negative results in pivot shift test. The extension and flexion spheres of knee activity were normal in 13 cases and were l imited in 2 cases. The Lysholm score was 95.1 ± 2.1, showing significant difference when compared with the preoperative score (t=43.020, P=0.000). Conclusion Multi-spot suture fixation under arthroscope is an effective method with small invasion, rel iable fixation, and simple operation for treating tibial intercondylar anterior eminence fracture.

  • STUDY ON EVALUATING SEX DETERMINING REGION OF THE Y AS A ENGRAFTING TRACK OF BMSCs TRANSPLANTATION FOR REPAIRING OSTEONECROSIS OF THE FEMORAL HEAD OF RABBIT

    Objective To evaluate sex determining region of the Y (Sry) as a engrafting track of the transplanted BMSCs survival and new bone formation in the osteonecrosis of the femoral head (ONFH) of rabbit. Methods Fortynine 4-5-month-old New Zealand White rabbits were included, weighing 2.0-2.5 kg, 48 females and 1 male. BMSCs of the rabbits were isolated by density gradient separation method, the third passage cells were marked by 1, 1’-dioctadecyl-3, 3, 3’, 3’-tetramethyl indocarbocyanine perchlorate (DiI) and the concentration of cell suspension was 2.5 × 108/ mL. The animal model of ONFH were establ ished with 48 female rabbits by injecting l iquid nitrogen, and femoral head was not dislocated.The animal model were divided into 3 groups, 16 rabbits in each group. Group A only establ ished animal model as control. Autologous BMSCs (4 μL) marked by DiI was transplanted in the ONFH models of the group B. Allogenic BMSCs (4 μL) marked by DiI was transplanted in ONFH models of the group C. The femoral head were observed by X-ray, HE staining and Masson staining, and the regenerating trabecular volume percentages was determined at 2, 4, 6 and 8 weeks after operation respectively. The examples of the heart, lung, l iver, spleen and kidney were obtained. The transplanted BMSCs were traced by fluorescence microscope, the Sry gene expression was detected by PCR for cells survival. Results All rabbits survived till the end of experiment. The X-ray showed gradual necrosis in the femoral head of group A. HE and Masson staining results indicated that compared with the group A, the recovery condition of the necrotic femoral head in the groups B and C was better. At each time of groups B and C, the regenerating trabecular volume percentages were higher than that of the group A significantly (P lt; 0.01). There was no significant difference between groups B and C (P gt; 0.05). The cells marked by DiI were not founded in the tissues of the heart, lung, l iver, spleen and kidney in groups B and C at each time. PCR showed that the expression of Sry gene were not observed at the heart, lung, l iver, spleen and kidney of three groups at each time. The expression of Sry gene was clearly identified in the femoral head of all 16 rabbits in the group C at each time point. Conclusion Allografting of BMSCs transplanted into the femoral head can survive and induce new bone formation without redistribution.
