Objective To observe the effects of autologous myoblast transplantation on endplate regeneration and neuromuscular function restoration following direct nerve implantation (DNI) in rats so as to offer experimental basis for the use of myoblasts in neural regeneration area and further lay foundation for the research using myoblasts as transgenic carriers. Methods A total of 20 male SD rats were randomly divided into experimental group and control group,with 10 rats in each group.Models of DNI in rat gastrocnemius were established.The experimental group was injected with primarily cultured autologous myoblasts to the DNI location,while the control group was injected with isometric medium without autologous myoblasts.The effects of myoblasts on the neuromuscular function recovery following DNI were studied by detecting the tibial functional index (FTI),neuro-electrophysiology and pathohistology.Results The experimental group displayed faster tibial nerve function recovery than the control group (P ＜ 0.01 ).The peak to peak value (PPV) of gastrocnemius neuro-electrophysiology,area under the curve and regenerated endplate number of the experimental group had statistical significances as compared with the control group ( P ＜ 0.01 ). Conclusion Myoblast autotransplantation accelerates the recoveryof neuromuscular function after rat DNI and increases the number of the regenerated endplates.

Objective To investigate the effects of local wet hyperthermia combined with microwave ablationon tumor growth and serum levels of interferon-β(IFN-β)and interleukine-12(IL-12).Methods An experimental mouse model beating mammary carcinoma was established in Balb/c mice and then treated with microwave ablation after 14 d.Seven d after ablation,local wet hyperthermia was administered once weekly for 2 weeks.Tumor growth and lung metastasis,as well as the survival of bearing tumor mice were observed.The serum levels of IFN-β and IL-12 were detected with enzyme-linked immuno sorbent assay(ELISA). Results When local wet hyperthermia was combined with microwave ablation tumor growth and lung metastasis were significantly less than when microwave ablation or local wet hyperthermia was used alone(P＜0.05).Furthermore,the survival of bearing tumor mice in combined therapy group prolonged significantly compared with those receiving either therapy alone(P＜0.05).Serum levels of IFN-β and IL-12 were also significantly higher in combined therapy group compared with the other groups (P＜0.05). Conclusions Local wet hyperthermia combined with microwave ablation is more effective than either local wet hyperthermia or microwave ablation alone in retarding tumor growth,which may be related to the enhanced immune response.

Objective To observe the effect of electroacupuncture (EA) and acupuncture (A) on the proliferation of stem cells in the subependymal zone (SPZ) of the lateral ventricle and the frontal lobe cortex in hyperlipemia(HL) combined with cerebral ischemia (CI) rats. Methods A total of 72 male SD rats were randomized into control,HL,HL+ EA,CI,CI+A,HL+CI,HL+CI+EAⅠ and HL+CI+EAⅡgroups (n= 9 /group).HL model was established by feeding the animals with high fat forage for 6 weeks and CI model was established by FeCl3-induced occlusion of the unilateral middle cerebral artery. EA was applied to "Sanyinjiao" (SP 6) and "Fenglong" (ST 40) once daily for 17 days for HL+ EA group; and acupuncture to "Baihui" (GV 20) and "Shuigou" (GV 26) once daily for 7 days for CI+A group. For HL+CI+EA Ⅰ group,EA was applied to SP 6+ST 40 first before CI,once daily for 10 days,followed by EA of SP 6+ST 40 and acupuncture of GV 20+GV 26 for 7 days after CI. For HL+CI+EA Ⅱ group,no treatment was given before CI,then,acupuncture of GV 20+GV 26 and EA of SP 6+ST 40 were given once daily for 7 days after CI.The immunoactivity of Nestin and proliferation cell nuclear antigen (PCNA) of SPZ was detected by immunohistochemistry.Results In comparison with normal control group,the numbers of both Nestin and PCNA immunoreaction (IR) positive cells in the dorsolateral extension and the wall of the lateral ventricle of the brain increased significantly in CI and HL+CI groups (P0.05). Conclusion EA can upregulate Nestin and PCNA expression of the dorsolateral extension and the wall of the lateral ventricle of the brain on the ischemic side in rats with CI,and with HL+CI,which may contribute to its effects in promoting the proliferation and migration of neural stem cells in the brain.

Objective To study the change of maternal serum human chorionic gonadotropin(MShCG) in preterm labor and the relationship between hCG and placental pathological changes. Metheds The preterm labor patients were chosen as the research subjects, the normal late-pregnancy women with the same gestational age were chosen as controls. MShCG level were measured by radioimmunoassy (RIA), placental tissue of preterm labor women was examined histologically. hCG in placental tissue was examined by semiquantiative immunohistochemistry. Results MShCG in preterm labor was significantly higher than that of control P

Objective To explore the relationship between plasma prothrombin activity (PTA) and histopathological lesion of the liver in patients with viral hepatitis. Methods A retrospective review of plasma PTA level and hepatohistological grading was performed in 234 patients with chronic hepatitis B (CHB) and 54 patients with severe hepatitis diagnosed both clinically and pathologically. Results PTA level was obviously negatively correlated with the hepatohistological Ishak score (P

Objective To explore the effect of preventive antibacterial treatment on spontaneous bacterial peritonitis (SBP) in the patients with severe hepatitis. Methods 120 cases of the patients with severe hepatitis were divided into two groups randomly. The patients in group A (n=62) received preventive antibacterial treatment except therapy for protecting liver. The patients in group B (n=58) only received therapy for protecting liver and served as control. Results In the group A and group B, the SBP frequency was 27.4% (17/62) and 44.8%(26/58) respectively (? 2=3.95,P

OBJECTIVE To investigate clinical characteristics of spontaneous bacterial peritonitis(SBP) in patients with severe type of viral hepatitis.METHODS A retrospective review of 120 cases of SBP associated with severe type of viral hepatitis was performed.RESULTS Clinical manifestations were as follows:fever 85.0%,abdominal tenderness 51.6%. 63.3% of the total white blood cells count in the ascitic fluid under 0.5×109／L,85.0% of polymorphonuclear cell ratio above 0.50.The positive culture of the ascitic fluid 24.2%,whereas 42.9% of the isolated microorganisms were Escherichia coli.CONCLUSIONS Clinical manifestations in SBP may be non-specific or absent.The total white blood cells count in the ascitic fluid are often under criteria for diagnosis.E.coli was the most common culture isolate.PMN ratio is the reliable parameter for the diagnosis of SBP.

Medical physics is the important basic for rapid development of model medical theory and technology.Innovation to physical education prompts the progress of high-level medical education.This study based on relevant educational practice will be beneficial to the progress of high-level medical education through primarily exploring the reforming of educational objective,educational model,educational instrument and educational teaching content.
