BACKGROUND: We have paid more attention on the effects of growth factors on tendon healing and adhesion formation, especially on the correlation of transforming growth factor with tissue adhesion and scar formation. OBJECTIVE: To investigate the expression of transforming growth factor beta-1 mRNA in the zone Ⅱ flexor tendon of wound-healing rabbit models. DESIGN: Randomized controlled animal study. SETTING: Department of Orthopaedics, Affiliated Hospital of Medical College, Qingdao University. MATERIALS: Sixty clean adult New Zealand white rabbits weighting 4.0-4.5 kg, of either sex, were provided by Qingdao Animal Experimental Center. Left forelimbs of each animal were as experimental side, and right forelimbs of each animal were as control. There were 6 time points, namely at days 1, 7, 14, 21, 28 and 56, 10 rabbits in each time point. Of the 10 rabbits, 6 rabbits received the in situ hybridization and 4 rabbits received the immunohistochemical staining. Animal intervention met the animal ethical standard. METHODS: Experiments were performed at the Animal Experimental Center of Hospital Affiliated to Medical College of Qingdao University from September 2005 to July 2006. After anesthesia, each rabbit underwent complete transection of the profundus middle flexor tendon in zone Ⅱ, and then the tendon was repaired by the Kessler method. Rabbits in the control group did not receive any intervention. Rabbits were anesthetized and killed 1, 7, 14, 21, 28 and 56 days after the surgery. Skin was incised along the original incision at the experimental sides to obtain tendons and tendon sheaths. The same measurements were performed in the control group. MAIN OUTCOME MEASURES: Tenocytes and tendon sheath cells were detected with the in situ hybridization and the immunohistochemical staining to observe the expression of transforming growth factor beta-1. RESULTS: Sixty rabbits were involved in the result analysis. ①The in situ hybridization results: Expression of transforming growth factor beta-1 mRNA was increased at day 1 after tendon injury in the experimental group, reached a peak at days 14-21 after tendon injury, reduced at day 28 and was still in a high level at day 56. Expression of transforming growth factor beta-1 mRNA was high in tendon sheath cells around the repaired region. At the same time point, the expression of transforming growth factor beta-1 mRNA was higher in tendon sheath cells than in tenocytes. Low expression of transforming growth factor beta-1 mRNA was found in tenocytes and tendon sheath cells in the control group. The expression of transforming growth factor beta-1 mRNA in tenocytes and tendon sheath cells was higher in the experimental group than in the control group at each time point (P < 0.05). ②Immunohistochemical staining results: Expression of transforming growth factor beta-1 protein was elevated at day 1 after the surgery, reached the peak at days 14-21 and was still in a high level at day 56 in the experimental group. Low expression of transforming growth factor beta-1 protein was seen in the control group. CONCLUSION: The normal uninjured tenocytes and tendon sheath cells produce transforming growth factor beta-1. The cytokine is activated in the injured tendon. The increase of this cytokine in both tenocytes and tendon sheath fibroblasts are coincidence with both extrinsic and intrinsic mechanisms for tendon repair.

Objective To observe the effect of parecoxib united with local anaesthesia analgesia system on analgesia after radical resection of liver cancer. Methods Ninety patients undergoing elective radical resection of liver cancer were randomly assigned to three groups, with 30 patients in each group. The patients in parecoxib group (P group) received parecoxib 40 mg through vein before the end of operation for 30 min, and were injected parecoxib 40 mg at 12 h, 24 h and 46 h after operation. The patients in local anethsia analgesia system group (L group) received embedding hypodermic pervasion canal in incision subcutaneously, then connected the pump with 0.25% ropivacaine 250 ml, with infusion speed of 4 ml/h.The patients in united group(U group)receiced the same methods with those in P group and L group. When the patients'visual analogue scale (VAS) scores were higher than 5 scores, they were given muscle injection of pethidine 50 mg. The VAS scores and Ramsay sedation scores at the time of tracheal extubation (T0), postoperative 2 h(T1), 6 h(T2), 12 h(T3), 24 h(T4) and 48 h(T5), the adverse reaction rate, dosage of pethidine, and analgesia satisfaction were compared. Results The resting and movement of VAS scores and Ramsay sedation scores at each time in P group and L group had no significant difference (P>0.05). The resting and movement of VAS scores and Ramsay sedation scores at each time in U group were significantly better than those in P group and L group (P<0.05). The rate of nausea and vomiting in three groups had no significant difference among three groups (P > 0.05). The rate of drowsiness in U group was significantly lower than that in P group and L group:6.67%(2/30) vs. 26.67%(8/30) and 23.33%(7/30), P < 0.05. The analgesia satisfaction in U group was significantly higher than that in P group and L group:93.33%(28/30) vs. 56.67%(17/30) and 53.33%(16/30), P<0.05. Conclusions The analgesia effect of the parecoxib united with local anaesthesia analgesia system for radical resection of liver cancer is perfect.

BACKGROUND:As bone marrow mesenchymal stem cel s can be differentiated into osteoblasts under certain induction conditions, autologous bone marrow mesenchymal stem cel s can be implanted into the bone nonunion site of bone fracture. This new technology garners increasing attention of orthopedic clinicians.
OBJECTIVE:To summarize the clinical efficacy of transplantation of bone marrow mesenchymal stem cel s in the treatment of bone nonunion of limb fractures.
METHODS:A computer-based search of Foreign Medical Journal Ful-Text Service and CNKI databases was performed for articles related to bone marrow mesenchymal stem cel s for treatment of bone nonunion of limb fractures published from 1998 to 2014 using the keywords of“bone marrow stem cel s (BMSCs), stem cel transplantation (SCT), nonunions, tissue engineering”in English and Chinese, respectively. Literatures with repetitive content and lack of originality were excluded. A total of 36 literatures were obtained for further analysis. RESULTS AND CONCLUSION:Bone marrow mesenchymal stem cel s are transplanted into the end of bone nonunion, and then can be induced to differentiate into osteoblasts to repair bone nonunion and bone defects,
laying a theoretical basis for clinical application. Bone marrow mesenchymal stem cel s can repair bone defects, which provides an effective method and material to promote fracture healing. Transplantation of bone marrow mesenchymal stem cel s is safe and effective for treatment of bone nonunion of limb fracture.

In recent years, the incidence of pancreatic cancer shows rising trend and higher mortality. Pancreatic cancer lacks early diagnostic methods with high sensitivity and specificity, and the surgical resection rate is 10 %-20 % with high operation mortality, poor long-term curative effect and less than 5 %survival rate within 5 years. At present, researchers indicate that radiotherapy can improve the quality of life, increase tumor local control rate and prolong the overall survival time of patients with pancreatic cancer in different levels. Diffusion weighted imaging (DWI), as a functional imaging technology of magnetic resonance imaging (MRI), is the only way to react cell levels. This paper will summarize the application of DWI in radiotherapy of pancreatic cancer.
