Enterovirus 71 (EV71) is a member of the Entero-virus genus of the Picornaviridae family and is the major cause of Hand,foot,and mouth disease (HFMD) in children.Different strains from Gansu were cloned and the P1 protein was sequenced and analysed.Results indicate that there are three kinds of EV71 infections prevalent in Gansu.The VP1 protein from one of these strains,55F,was expressed.The recombinant protein was expressed with high level and reacted specifically with the EV71 patient antibody,the recombinant protein was also applied to raise antiserum in rabbits and after the fourth injection a high titer of antiserum was detected by ELISA assay.These data are useful for further clarification of prevalent EV71 strains in the north of China at the molecular level and provide a basis for EV71 diagnosis.

This study was aimed to investigate the effects of extract from Tibetan medicine Berberis Cortex (TMBC) on expressions of protein kinase C (PKC-β), vascular endothelial growth factor (VEGF) and hypoxia-inducible factor (HIF-1α) in the retina of diabetic rats. Diabetic rats were established by one time intraperitoneal injection of strepto-zocin (STZ). Rats were randomly divided into the model group, low-dose TMBC group, medium-dose TMBC group, high-dose TMBC group, metformin group, calcium dobesilate group, berberine group and the normal control group. Intragastric administration was given. The medication amounts of TMBC in the low-dose, medium-dose and high-dose group were 5, 10, and 20 times to the adult medication dose. In the metformin group and the berberine group, 10 times of the adult medication dose were given. Distilled water was given in the model group and the normal con-trol group. After 6-week intragastric administration, all experimental rats were sacrificed. The expressions of PKC-β, VEGF and HIF-1α were examined by real-time fluorescence quantitative PCR assay and western blot. HIF-1α ex-pression was detected by immunohistochemistry. The results showed that compared with the normal control group, the mRNA and protein expression of PKC-β, VEGF and HIF-1α increased obviously in the retina of diabetic rats ( P<0.01). Compared with the model group, the mRNA expression of PKC-β, VEGF and HIF-1α in the high-dose and medium-dose TMBC group reduced obviously (P< 0.01). The protein expression levels of PKC-β, VEGF and HIF-1α were also obviously reduced (P< 0.05). The expressions of PKC-β, VEGF and HIF-1α in the low-dose TMBC group were obviously reduced (P < 0.05). It was concluded that TMBC can depress the expressions of HIF-1α, PKC-β and VEGF in the retina of diabetic rats, which can be served as a protective effect to prevent progress of di-abetic retinopathy.

BACKGROUND: At present the strategy of nerve regeneration and repairng are main promoting nerve intrinsic regeneration capacity and improving the micro-environment. Studies have shown a number of combined treatment which could promote the regeneration and growth of nerve axon.OBJECTIVE: To explore the feasibility and effect of rat spinal cord injury repaired by peripheral nerve combined growth factor. METHODS: Sixty healthy adult female SD rats were randomly divided into 4 groups: nerve graft group, nerve graft combined growth factor group, spinal cord transaction group and laminectomy group. Taking T_9 as the center, a longitudinal incision was conducted in rat skin, revealing dural sac, spinal cord was transected and removed 3 mm, 2-cm segment of the eighth to tenth intercostal nerve was obtained from nerve graft group and nerve graft combined with growth factor group, autologous intercostal nerve was cross-transplanted into spinal defect (proximal white matter and distal gray matter, distal white matter and proximal gray matter) after pruning appropriately. The transplanted intercostal nerves were fixed with fibrin glue in nerve graft group, while those in nerve graft combined growth factor group were fixed with fibrin glue containing 2.1 mg/L acidic fibroblast growth factor, followed by dural suture～ Stump of broken ends was done in spinal cord transection group, while laminectomy was performed in laminectomy group. RESULTS AND CONCLUSION: At 90 days post-surgery, somatosensory evoked potential (SEP) and motor evoked potential (MEP) were determined, the motor function of hind limbs was evaluated by the Basso. Beattie.Bresnahan (BBB) test at 70 days. Both SEP and MEP were led in the laminectomy group, but not lead in spinal cord transection group; in nerve graft group, 3 rats showed bilateral SEP, 4 led unilateral SEP, 4 led bilateral MEP, 3 led unilateral MEP; in nerve graft combined with growth factor group, 5 led bilateral SEP and 2 led unilateral SEP, 5 led bilateral MEP and 2 led unilateral MEP. The SEP and MEP latency and amplitude in the nerve graft group and nerve graft combined growth factor group were significantly superior to the spinal cord transection group (P < 0.01), autologous rib nerve graft group was better than nerve graft combined growth factor group (P <0.01). In the laminectomy group, awake rats following anesthesia returned to normal exercise, rats in spinal cord transection group continued to extend limbs and rotated within 3 months, rats in other two groups recovered functions obviously 3 weeks post-surgery and gradually restored throughout the entire observation period. Nerve graft group and nerve graft combined growth factor group showed significantly increased BBB score compared with spinal cord transection were (P < 0.01), and the nerve graft combined growth factor group was superior to nerve graft group (P < 0.01). The peripheral nerve graft can promote the spinal function following spinal cord injury, while the nerve combined growth factor can better restore the function.

BACKGROUND: Transforming growth factor (TGF)-β_1, a potent cell growth and proliferation regulatory proteins, plays an important role in development of anti-graft rejection and graft vascular disease. OBJECTIVE: To observe local injection of TGF-β_1 effects on transplant immune rejection following freezing disposal and nerve allograft. DESIGN, TIME AND SETTING: The randomized controlled animal study was performed at the Animal Experimental Center, Harbin Medical University from June 2007 to June 2008. MATERIALS: A total of 60 clean SD rats (recipients) were divided into 3 groups: autogenous nerve graft group, nerve allograft group, TGF-β_1 plasmid + nerve allograft group, 20 in each group. A total of 40 Wistar male rats served as donors. pAdTrack-CMV-TGF-β_1 plasmid, pAdEasy-1-Bj51833 cells were presented by the Orthopedic Laboratory of Fourth Hospital of Harbin Medical University. METHODS: Longitudinal posterolateral incision was made in 40 donor rats to expose sciatic nerve. The whole bilateral sciatic nerve was cut and placed in sterile frozen tubes for 1 week for use. Under the microscope, connective tissue was cut in the biceps muscle and semi-tendon and semi-membrane gap of recipient rats to expose the sciatic nerve. 1-cm sciatic nerve was cut 0.5 cm below the muscle from the plow-shaped hole. Transplantation of frozen autogenous nerve graft and nerve allograft (nerve at equal size) was separately performed in the autogenous nerve graft and nerve allograft groups. In the TGF-β_1 plasmid + nerve allograft group, pAdTrack-CMV-TGF-β_1 plasmid (40 μg) was injected into the local muscle and two sides of transected sciatic nerve of each rat following nerve allograft transplantation. MAIN OUTCOME MEASURES: Motor nerve conduction velocity, pathology and axonal counting were examined 3, 6, 9 weeks after surgery. RESULTS: Motor nerve conduction velocity was higher in the TGF-β_1 plasmid + nerve allograft group than in the nerve allograft group (P < 0.01), which did not show significant difference compared with the autogenous nerve graft group. Axonal counting was greater in the autogenous nerve graft and TGF-β_1 plasmid + nerve allograft groups compared with the nerve allograft group 9 weeks following surgery (P < 0.01). Using optical microscope and electron microscope, nerve fibers were normal and well arranged in the TGF-β_1 plasmid + nerve allograft group. Nerve fibers presented vascular proliferation, good myelin sheath. Abundant regenerated myelin sheath was found in nerve fiber. The number of Schwann cells was obviously increased, and there were prosperous cytoplasm, a large amount of rough endoplasmic reticulum, clear mitochondria. In regenerated axons, microfilament closely arranged, which was similar to the autogenous nerve graft group. In the nerve allograft group, the optical microscope and electron microscope showed a few nerve fibers, disorderly arranged, significant demyelination, axon degeneration and disappearance, without regenerated fibers. CONCLUSION: Local injection of TGF-β_1 plasmid could reduce immune rejection after cold sciatic nerve allograft transplantation.
