BACKGROUND: Non-adherent mesenchymal stem cells (NA-MSCs) can form colony forming unit of fibroblasts and induce the differentiation into adipocytes, osteoblasts, and chondrocytes. OBJECTIVE: To determine the effect of epithelial growth factor (EGF) on colony formation of fibroblasts and differentiation into neuron-like cells from NA-MSCs.METHODS: Bilateral femur and tibia as well as total MSCs were separated, and repeated-transfer was employed to purify NA-MSCs. The fifth-passage total MSCs and NA-BMCs were induced in a medium containing EGF and basic fibroblast growth factor (b-FGF) for 2 weeks. Colony unit formation of fibroblasts, effect of EGF on colony-forming unit of fibroblasts, and relative protein expression detected by toluidine blue and immunocytochemical staining were observed. RESULTS AND CONCLUSION: Both total MSCs and NA-BMC could generate colony-forming unit of fibroblasts. After treatment of EGF, colony-forming unit of fibroblasts from NA-BMC was increased significantly. Immunocytochemical staining demonstrated that two weeks later both neuro-specific NeuN and NF-200 were observed in total MSCs and NA-BMC; while, toluidine blue staining indicated that neuron-specific Nissl body was observed in some cells. EGF can effectively promote colony-forming unit of fibroblast from NA-BMC, and repeated-transfer NA-BMC can induce differentiation into neuron-like cells.

Objective To investigate the changes in the expression of calcitonin gene-related peptide (CGRP), substance P (SP) and brain-derived neurotrophic factor (BDNF) in dorsal root ganglion (DRG) and the effect of electroacupuncture (EA) on morphine tolerance in rats with chronic inflammatory pain (CIP) and morphine tolerance. Methods Twenty-five 8-month-old male SD rats weighing 230-250 g in which intrathecal (IT)catheters were successfully implanted without complications were randomly divided into 5 groups ( n = 5 each):groupA CIP + normal saline (NS) 10 μl IT twice a day for 7 consecutive days; group B CIP + morphine 10 μg/kg ( 10 μl) IT twice for the first day only; group C CIP + morphine 10 μg/kg ( 10 μl) IT twice a day for 7 consecutive days; group D CIP + EA (intensity 2 mA, frequency 2 Hz, wave length 0.6 ms) + morphine 10 μ g/kg (10 μl) IT twice a day for7 consecutive days; group E CIP + EA (intensity 2 mA, frequency 15 Hz,wave length 0.4 ms) + morphine 10μg/kg (10 μl) IT twice a day for7 consecutive days. CIP was induced by injecting complete Freund's adjuvant (CFA) into the ankle joint of the left hindlimb. IT morphine or NS was started on the 4th day after induction of CIP. EA of Yanglingquan and Zusanli lasting 30 min was performed once a day after first IT administration of morphine for 7 days. Paw withdrawal latency (PWL) to a thermal nociceptive stimulus was measured before induction of CIP, 1 day before (baseline) and at day 1-7 after administration (T0-8) . The animals were sacrificed after the last PWL measurement. The DRGs of the lumbar segment (L4-6) were removed for determination of CGRP, SP and BDNF mRNA expression using RT-PCR. Results PWL was significantly shorter at T1 than at T0 in all groups, and at T3-8 than at T2 in group B-E, while longer at T2 than at T1 in group B-E ( P ＜0.05). PWL was significantly longer in group B-E and CGRP, SP and BDNF mRNA expression higher in group C than in group A ( P ＜ 0.05). PWL was significantly longer in group C-E than in group B ( P ＜ 0.05). PWL was significantly longer and CGRP, SP and BDNF mRNA expression lower in group D and E than in group C ( P ＜0.05). PWL was significantly lower and CGRP, SP and BDNF mRNA expression higher in group E than in group D ( P ＜ 0.05). Conclusion Up-regulation of the expression of CGRP, SP and BDNF mRNA in DRG is involved in the devepopment of morphine tolerance. EA can inhibit the devepopment of morphine tolerance by inhibiting the expression of CGRP2 SP and BDNF mRNA.

BACKGROUND:The treatment of calcaneal fractures using open surgery is likely to cause greater trauma. OBJECTIVE:To explore the clinical effect of steinmann pin poking closed reduction axial combined with lateral multiple hol ow screws internal fixation in repair of Sanders II, III type calcaneal fractures. METHODS:The clinical data of 73 patients with Sanders II, III type calcaneal fractures were retrospectively analyzed and divided into conventional group (n=36) and experimental group (n=37) according to the treatment method. Patients in these two groups were respectively treated with conventional open reduction internal fixation and steinmann pin poking closed reduction axial combined with lateral multiple hol ow screws internal fixation. RESULTS AND CONCLUSION:Compared with the conventional group, the hospital stays of patients in experimental group were shorter, hospital costs reduced. There were no obvious changes in the foot rating from the American Association of Ankle Injuries, B?hler angle and Gissane angle. The incidence of complications was significantly decreased. These results demonstrate that the treatment of Sanders II, III type calcaneal fractures with conventional open reduction and bone plate internal fixation and steinmann pin poking closed reduction axial combined with lateral multiple hol ow screws internal fixation can obtain the basic equivalent clinical effect, however, the treatment of steinmann pin poking closed reduction axial combined with lateral multiple hol ow screws internal fixation have more obvious advantages, such as a shorter hospital stays, less hospital costs, and also can effectively control the complications.

Objective To investigate the effect of the gene polymorphism of cholesterol ester transfer protein (CETP) on the serum lipid levels in renal transplant patients.Methods Serum total cholesterol (TC),triglyceride (TG),low density lipoprotein (LDL),high density lipoprotein cholesterol (HDLC),apolipoproteins (Apo A1,B,E) and lipoprotein(a) [Lp(a)] were measured. Polymerase chain reaction-restriction fragment length polymophism (PCR-RFLP) was used to detect CETP gene polymorphism in renal transplant recipients.Results Serum levels of TC,TG,HDLC,LDLC,ApoB,ApoE in the renal transplant recipients were increased significantly after transplantation. The allele frequency and the distribution of the TaqⅠ(intron 1) and MSPⅠ(intron 8) genotypes showed no significant difference between the controls and the renal transplant recipients. The serum TG level was significantly higher in renal transplant recipients with the genotype TaqⅠB1/B1 than those in the patients with genotype TaqⅠ B1/B2 and B2/B2. But there was no statistical difference among the serum lipid levels in renal transplant recipients with different MSPⅠgenotypes.Conclusion The serum lipid levels were increased significantly in transplant after transplantation,and the patients with CETP genotype TaqⅠB1/B1 liable to develop hypertrglyceridemia.

OBJECTIVE:To observe the other effects of cimetidine in the decompensated stage of chronic cardiopulmonary disease. METHODS: 72 patients with uncompensated chronic cardiopulmonary disease were assigned into therapy group and control group (n=36). Both groups were given routine treatment. Therapy group were additionally treated with cimetidine intravenously for 48 h. The changes of respiration frequency, arterial partial pressure of oxygen (PaO2), arterial partial pressure of carbon dioxide (PaCO2), intake of staple food and electrolytes in blood serum of 2 groups before and after treatment were determined. RESULTS:In therapy group, the respiration frequency, the level of PaCO2 and disorder of electrolytes in blood serum were decreased and the level of PaO2 and intake of staple food were increased. Above items of therapy group were all different from that of control group (P

Objective To explore the effects of fat on healing of porcine skin wounds so as to provide a new strategy to promote skin wound repair after injury. Methods Forty-eight full-thickness skin wounds were produced on both sides of the back in 6 male minipigs (8 wounds in each animal). These wounds were then randomly divided into 4 groups, i.e. saline control group, fat autografting group, fibroblast growth factor (bFGF) treatment group and epidermal growth factor (EGF) treatment group. On day 3, 7, 14 and 21 after wounding, the area and the volume of wounds were measured, and histological examination was performed to evaluate the speed and quality of wound healing in different groups. Results On days 3 and 7, the amount of granulation tissue and vessel density in fat treatment group were significantly more abundant compared with other groups. Wound area and volume in fat treatment wounds were markedly decreased compared with those in other groups (P
