Objective To explore the effect of adenovirus-mediated bcl-2 transfer on the regeneration and repair of peripheral nerves in rats. Methods The sciatic nerve-transected model was selected and sutured end to end with epineurium. Then, adenovirus/sense-B-lymphoma/leukemia-2 (Ad/s-bcl-2), adenovirus/anti-sense-B-lymphoma/leukemia-2 (Ad/as-bcl-2), adenovirus/?-galactosidase (Ad/LacZ) and normal saline (NS) were injected into the sciatic nerve 0.5 cm away from the sutured point respectively. The rats were perfused with 4% paraformaldehyde at the 48th hour, 7th, 15th and 30th days respectively after operation. The spinal cords L 4-6 were harvested, frozen sectioned and given x-gal staining, bcl-2 in situ hybrid and immunohistochemical staining and GAP-43 immunohistochemical staining. The postoperative functional recovery of the rear limbs of rats was dynamically observed by using sciatic nerve functional index (SFI). Results The GAP-43 expression in the motor neurons of anterior horn of spinal cord in group Ad/s-bcl-2 was higher than that in other groups (P0.05). Conclusions Gene transfer of bcl-2 can promote regeneration and functional recovery of the peripheral nerves following sciatic nerve injury.

ObjectiveTo observe the effect of auricular acupuncture combined with physical therapy on motor function of stroke patients.Methods40 stroke patients were divided randomly into trial group and control group with 20 cases in each group. Patients of trail group were treated with auricular acupuncture combined with physical therapy; cases of control group were treated only with physical therapy. Motor function of all patients were assessed with Fugl-Meyer Assessment (FMA) before and after treatment.ResultsFMA scores of patients of trial group increased significantly compared with that of control group (P<0.01).ConclusionEffect of auricular acupuncture combined with physical therapy is better than that of single physical therapy on motor function of the stroke patients.

Objective: To evaluate the biocompatibility of 3 kinds of artificial, biodegradable graft materials, including T20 [Poly (butylene terephthalate)-co-poly (cyclohexylene dimethanol terephthalate)-b-poly (ethylene glycol)], PHBV (Poly3-hydroxybutyrate-Poly3-hydroxyvalerate) and PEGT/PBT [Poly (butylene terephthalate)/poly (ethylene glycol) terephthalate], and to study their effects on canine smooth muscle cells(SMCs) growth after surface modification. Methods: The contact angles were measured to compare the hydrophilicity of T20, PHBV, and PEGT/PBT scaffolds. Then SMCs were cultivated on these biodegradable scaffolds; their proliferation and growth were assayed by MTT assay, FITC and electron microscopic observation for evaluation of their in vitro biocompatibility. The growth of SMCs was also assayed on the 3 scaffolds after they were pretreated with gelatin or Poly-1-lysine. Results: The contact angles of 3 scaffolds were all less than 90°(PEGT/PBT>T20>PHBV). MTT assay showed that SMCs adhered to and grew well on T20, PHBV, and PEGT/PBT scaffolds. The cell viability began to increase 24 h after cultivation (PEGT/PBT>T20>PHBV, P<0.01), followed by a decrease, but increased again 72 h after cultivation (T20>PEGT/PBT>PHBV, P<0.01). FITC observation showed that SMCs grew well and electron microscopic observation showed a confluent growth of SMCs with abundant extracellular matrix. The viability of SMCs was significantly higher on scaffolds pretreated with gelatin or Poly-1-lysine than on those without pretreatment(P<0.01). Conclusion: T20, PHBV, PEGT/PBT have good in vitro biocompatibility; the scaffolds made of these materials can obviously improve cell attachment after surface modification.

Objective To approach rehabilitation nursing measures in using the allogeneic ten-don to re-establish the anterior cruciate ligament of knee through the tibia twin tunnel under arthroscopy.Methods Mental nursing and direct functional exercises was given to 30 patients who received this kind of operation from November,2006 to July,2007,and functional exercises of flection and extention of knee joint by steps,functional exercises of muscle force of quadficeps muscle and back muscle group of legs and the correct using of artificial brace of knee joint.Results Range of joint motion could reach 95°after 2 weeks and 125°after 4 weeks postoperation.Score of joint function(Lysholm)could reach(74.8±5.7)after 6 weeks,(80.0±2.3)after 9 weeks,(91.8±3.4)after 12 weeks, and(94.5±2.2)after 1 year.Conclusion Selective perioperative rehabilitation nursing instruction is the important guarantee of function recovery.

OBJECTIVE:To investigate the effects of levocarnitine on peripheral blood T cell subsets and inflammatory factors in diabetic patients underwent peritoneal dialysis. METHODS:A total of 100 diabetic patients underwent peritoneal dialysis in se-lected as research objects were divided into conventional therapy group and levocarnitine group according to random number table, with 50 cases in each group. Conventional therapy group received peritoneal dialysis and conventional therapy. Levocarnitine group was additionally given levocarnitine 1.0 g added into 0.9% Sodium chloride injection 20 mL intravenously,3 times a week,on the basis of conventional therapy group for 12 weeks. CD3+,CD4+,the proportion of Th1 and Th2,the contents of TNF-α,INF-γ, IL-10 and IL-4 in supernatant were all detected before and after treatment. The expression of T-bet and GATA-3 were compared be-tween 2 groups. RESULTS:After treatment,CD3+,CD4+,Th2 cells,GATA-3 expression and IL-10,IL-4 levels were significantly increased,the expression of Th1 cells,T-bet content and TNF-αand INF-γwere significantly reduced,and levcarnitine group was sig-nificantly better than conrentional therapy group,with statistically significant (P<0.05). CONCLUSIONS:Levocarnitine can im-prove inflammatory reaction and the expression of related transcription factors by promoting T cell subsets and Th1/Th2 cell subsets.

All patients were given FOLFOX4, and the effects were evaluated according to World Health Organization criteria. Results The overall response rates to chemotherapy was 46%, expression of the 6 mtdtidrug resistance gene in 35 cases of stomach cancer tissues were as follows:GST-π was 40% ,LRP was 69% ,MRP was 34% ,Topo Ⅱ was 37% ,P-gp was 86%, TS was 40%, expression of the 6 muhidrug resistance gene did not change during neoadjuvant chemotherapy; GST-π、LRP、MRP、Topo Ⅱ、P-gp were not correlated with chemotherapy sensitivity(P > 0.05), while TS was significantly correlated with chemotherapy sensitivity (P = 0.0048). Conclusion FOLFOX4 does not effect a change in the expression of the 6 muhidrug resistance gene: GST-π、LRP、MRP、Topo Ⅱ、P-gp and TS, while TS is significantly correlated with gastric cancer chemotherapy sensitivity.

Objective To investigate the biological effect of 50 Hz sinusoidal electromagnetic fields at 1 mT on the proliferation of the human osteosarcoma cell line MG-63.Methods Osteosarcrma MG-63 cells were divided into control and experimental groups.The control group was incubated without an electromagnetic field; the experimental group was incubated in a 50 Hz,1.0 mT sinusoidal electromagnetic field.On the 2nd,4th and 6th day,their proliferation was determined using a cell counting kit-8(CCK-8)assay.Variations in the cell cycle were detected with flow cytometry(FCM).Semi-quantitative reverse transcription-polymerase chain reaction(RT-PCR)was used to measure cyclin B1 and cyclin D1 mRNA.Results Compared with the control group,proliferation of the experimental group cells was reduced significantly.The percentage of cells at G0-G1 phase increased,and the mRNA expression of cyclin B1 and cyclin D1 was significantly reduced.Conclusions A 50 Hz sinusoidal electromagnetic field at 1.0 mT can inhibit the proliferation of osteosarcoma cell line MG-63 significantly.
