Chinese Journal of Medical Imaging 2013;(6):428-430
Purpose To evaluate the application value of rapid exchange method in transnasal intestinal obstruction catheterization. Materials and Methods Fifty-eight patients with adhesive intestinal obstruction underwent transnasal catheterization under X-ray fluoroscopy, of which 31 cases were treated with rapid exchange catheterization method (group A) and the other 27 cases with traditional catheterization method (group B), success rate, operation time and complications were compared between the two groups. Results Catheterization success rate of group A and group B were 96.77%(30/31) and 77.78%(21/27) respectively, which was significantly higher in group A than in group B (χ2=4.907, P<0.05);operation time of group A and group B were (28.2±12.3) min and (25.4±15.7) min respectively, and the difference between them was not statistically significant (t=1.219, P>0.05); no operation associated injury occurred in group A and only one case in group B (3.70%) resulted in bilateral nasal edema with a small amount of bleeding because the operating time was too long, complication rate between the two groups was also not statistically significant (P>0.05). Conclusion Rapid exchange method can improve the success rate of transnasal intestinal obstruction catheterization, but the operation time and complications are comparative to those of the conventional method.

BACKGROUND:Trauma easily leads to the emergence of articular cartilage defects, which is a difficult problem in the orthopedics field. Tissue engineering technology provides a new method for cartilage repair. OBJECTIVE:To explore the feasibility of combining chitosan and bone marrow mesenchymal stem cels to repair injured articular cartilage in rabbits. METHODS: Cultured rabbit bone marrow mesenchymal stem cels were seeded onto chitosan scaffold, and then the composite material was implanted into the defect as experimental group. Rabbits with no treatment served as control group. Gross observation and toluidine blue staining were carried out at 6 and 12 weeks after operation. RESULTS AND CONCLUSION:At 6 weeks after operation, the control group had only fibrous tissue hyperplasia, and in the experimental group, cartilage-like tissues were generated at the defect site. At 12 weeks after operation, a smal amount of hyaline cartilage-like tissues were observed in the control group, and the defects in the experimental group were covered with smooth and hyaline cartilage tissues. After 12 weeks, the toluidine blue staining was light in the control group with a smal amount of cartilage tissues; in the experimental group, the toluidine blue staining was remarkable, and the defects were completely covered with hyaline cartilage tissues, and cartilage cels were increased in number. The findings indicate that chitosan-bone marrow mesenchymal stem cels composite material is better to induce cartilage tissue formation and promote cartilage defect repair.

BACKGROUND:With respect to mesenchymal stem cels from other sources, synovial mesenchymal stem cels are rich in source, and moreover, the synovial tissue can regenerate quickly after partial hepatectomy and lead to fewer complications, in recent year, which have become a hot spot in stem cel research. OBJECTIVE:To observe the proliferation and directional differentiation of synovial mesenchymal stem cels from osteoarthritis patients. METHODS:Synovial mesenchymal stem cels were isolated and cultured. MTT assay was used to detect cel proliferation ability. Alkaline phosphatase activity was detected quantitatively at 7 days of osteogenic induction, and osteogensis-related gene expression was measured at 7, 14, 21 days of osteogenic induction. Alizarin red staining was performed at 21 days of induction. RESULTS AND CONCLUSION:(1) Passage 3 synovial mesenchymal stem cels proliferated faster, which were in latent period at 1, 2 days after inoculation, in logarithmic growth phase at 3-6 days, and then entered into the plateau phase at 7 days. (2) The activity of alkaline phosphatase was significantly higher in the induction group than the control group at 3, 7, 10 days after osteogenic induction (P < 0.05). The cels were positive for alizarin red staining at 21 days of osteogenic induction, and there were calcium deposits and calcium nodules in the extracelular matrix. (3) Bone-binding protein and Runx2 were visible at 7 days of osteogenic induction, and reached the peak at 21 days. These findings indicate that synovial mesenchymal stem cels from patients with advanced osteoarthritis have strong proliferation ability, which can differentiate into osteoblasts under in vitro induction.

Objective To explore the reasons of biliary restenosis after interventional treatment for malignant obstructive jaundice caused by hepatic hilar cholangiocarcinoma and to discuss its management. Methods During the period from June 2010 to Sep. 2013 at authors’ hospital, a total of 36 patients with high biliary obstruction caused by Bismuth Ⅱ - Ⅳ type of hepatic hilar cholangiocarcinoma received percutaneous transhepatic cholangial stenting (PTCS), and as the patients developed biliary restenosis after PTCS percutaneous transhepatic cholangial drainage (PTCD) had to be carried out. All the patients had complete data. Serum total bilirubin, direct bilirubin, glutamyltranspetidase and alkaline phosphatase levels were determined on the operation day and at five days after PTCS and PTCD. The short - term remission of malignant obstructive jaundice produced by PTCS and PTCD were assessed. The causes of biliary restenosis were analyzed by comparing the CT and/or MRI images as well as the cholangiography and drainage test results which were performed at the first and second admission to hospital. Results The interval time from operation to restenosis was 31 - 468 days, with an average of 132.8 days. The effective rates of PTCS and PTCD for relieving jaundice were 77.8% and 75.0% respectively. The main causes of restenosis included the formation of biliary sludge, acute cholangitis and tumor growth. Conclusion PTCS is an effective means to relieve the malignant obstructive jaundice caused by hepatic hilar cholangiocarcinoma, however, the incidence of biliary restenosis after PTCS is higher, which may be mainly due to the tumor growth. Nevertheless, subsequent PTCD can effectively improve the liver function, control biliary infection, remit biliary obstruction and relieve the clinical symptoms.

OBJECTIVETo evaluate clinical outcomes of anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) reconstruction under arthroscopy and repair of the injured posteromedial complex structure of the knee joint in the treatment of posterolateral knee dislocation with multiple ligament injuries.
METHODSFrom March 2008 to August 2012,22 patients (16 males and 6 females, ranging in age from 20 to 53 years old, with an average of 30.5 years old) with posterolateral dislocation of the knee were treated with primary reconstruction of ACL and PCL, combined with the repair of injuries in the posteromedial complex and soft-tissue. Eight patients had injuries caused by sports,5 patients road accidents and 9 patients falling down. The ACL was reconstructed using the gracilis and semitendinosus tendons. The PCL was reconstructed using LARS artificial ligaments (14 cases), or gracilis and semitendinosus tendons (8 cases). Suture repair was performed in 17 patients with posteromedial ligament injuries,and self-semitendinosus strengthening operations were performed in 5 patients. Continuouspassive montion (CPM) and active exercises were executed after operation at early stage. The IKDC and Lysholm system were used to evaluate therapeutic effects.
RESULTSAll the patients were regularly followed up, and the duration ranged from 11 to 56 months (averaged, 39 months). According to the IKDC scale,9 patients got a grade A result, 10 got a grade B result, and 3 got a grade C result. The IKDC subject score was 89.6±3.1 and the Lysholm scores was 90.7±1.8 at the latest follow-up, which were both better than those before operation.
CONCLUSIONReconstructing the ACL and PCL and repairing injured posteromedial complex of the knee followed by an active rehabilitation is an effective method to treat posterolateral knee dislocation.
