In recent decades, the development of the neurosurgery has changed from the traditional anatomical model to the modern anatomical-functional model. The nerve functions are maximally protected while lesions are removed as far as possible. Neurophysiological monitoring especially somatosensory evoked potentials (SEPs) and motor evoked potentials (MEPs) can directly reflect the integrity of the sensory and motor nerve conduction pathways of the nervous system. At present, it has been widely used in the neurosurgery, spinal surgery, vascular surgery and other surgical fields. In recent years, more and more clinical surgeries involved spinal surgery, intraoperative neurophysiological monitoring could timely find any reversible spinal cord damage such as mechanical stretch, ischemia, and anesthetic drugs, which not only improve the quality of surgery, reduce iatrogenic spinal cord injury, but also greatly improve the prognosis of patients and reduce postoperative neurological dysfunction and complications. In this paper, the research progress of neural electrophysiological monitoring techniques in spinal cord surgery is reviewed.

Objective To explore the effect of psychological rehabilitation on patients with limb motor dysfunction. Methods 136 cases of hospitalized patients who needed rehabilitation therapy and training were divided into observation group and control group. The control group received conventional rehabilitation, and the observation group received psychological rehabilitation (psychotherapy and medicine) in addition. Symptom Checklist-90 (SCL-90), Fugl-Meyer Assessment (FMA) and modified Barthel Index (MBI) were assessed before and 8 weeks after treatment. Results Most of the 136 patients were involved in psychological problems, including anxiety, depression, somatization,fear, hostility. There was no difference in the scores of SCL-90, FMA and MBI between 2 groups before treatment (P>0.05). After 8 weeks treatment, the scores of SCL-90 were lower, except psychotism (P>0.05), in the observation group than in the control group (P<0.05),the scores of FMA and MBI were higher in the observation group than in the control group (P<0.01). Conclusion The psychological rehabilitation plays an important role in rehabilitation of limb motor dysfunction.

Aim To investigate the effect of intrauterine injection of rat fetal hepatocytes on homograft rejection reaction. Methods The skin graft from a male LOU/CN rat was transplanted to a female recipient CHN rat of 7 to 9 weeks after parturition, and then survival time of the graft was observed. Simultaneously, homograft rejection reaction was examined by mixture lymphocyte culture. Results As compared with control group, survival time of transplanted skin graft was obviously prolonged. Mixure lymphocyte culture demonstrated that homograft rejection reaction was inhibited markedly. Conclusion Intrauterine injection of rat fetal hepatocytes wuld obviously inhibite homograft rejection reaction, thus prolonging survival time of the graft.

Immunological rejection is the major barrier to successful transplantation.The immune response to an allograft is an ongoing dialogue between the innate and adaptive immune system that will lead to the rejection of allograft.Activation of elements of the innate immune system,triggered as a consequence of tissue injury sustained during cell isolation or organ retrieval and ischemia reperfusion,will initiate and amplify the adaptive response.Identifying the molecular pathways that trigger tissue injury,signal transduction and rejection facilitates the identification of targets for the development of immunosuppressants.

Objective To explore the clinical effect of transjugular intrahepatic portosystemic shunt (TIPS) and percutaneous transhepatic variceal embolization (PTVE) on the treatment of cirrhosis with esophageal gastric varices bleeding. Methods The data of 61 patients of liver cirrhosis combined with esophageal gastric varices bleeding who underwent the interventional treatment were included in the retrospective analysis. Patients were divided into two groups, PTVE treatment group (n=42), and TIPS treatment group (n=19). The success rate of clinical treatment, the rebleeding rate, the alleviation of varicose veins, the incidence of hepatic encephalopathy, survival rate and liver function parameters were compared between two groups. Results Two groups of surgery were successful. The portal vein pressure decreased obviously in TIPS group. The rebleeding rate was higher in PTVE group (78.6%) than that in TIPS group (63.2%). The total alleviation rate of esophageal gastric varices was significantly lower in PTVE group (50.0%) than that in TIPS group (89.5%, P<0.05). The incidence rates of hepatic encephalopathy were 14.3% and 26.3% for PTVE group and TIPS group respectively. The two-year cumulative survival rates of PTVE group and TIPS group were 95.2% and 89.5% respectively, and there was no statistically significant difference between two groups. After surgery, the liver function parameters were not significantly different from those determined before the treatment in PTVE group. At 1 month and 3 months after TIPS, the liver functions were declined obviously. At 6 and 12 months after the treatment, the liver functions were not significantly different from those determined before the treatment in PTVE group. Conclusion The surgery of TIPS is safe and ideal interventional treatment for cirrhosis with esophageal gastric varices bleeding, which has the lower rebleeding rate, better esophageal gastric varices alleviation rate and long term less influence in liver function.

Objective To study the therapeutic effect and mechanism of Dicliptera chinensis polysaccharide ( DCP) on liver injury induced by antituberculosis drugs. Methods Sixty mice were randomly divided into six groups, namely normal control group, model group, glucurolactone group (in the dosage of 200 mg·kg-1·d-1), and high-, middle- and low-dose DCP groups ( in the dosage of 600, 400, 200 mg·kg-1·d-1, respectively). Except for the normal control group, the rats in the other groups were given intragastric administration of isoniazid and rifampicin ( 100 mg/kg) to induce liver injury model, and were simultaneously treated with corresponding agents, once a day. On the experiment day 30, the blood and liver tissue were sampled. The serum levels of alanine aminotransferase ( ALT) , aspartate aminotransferase ( AST) , alkaline phosphatase ( AKP) and microsomal nitric oxide ( NO) were detected by biochemical method. The contents of tumor necrosis factor alpha (TNF-α) and interleukin 6 (IL-6) in liver tissue were determined by enzyme-linked immunosorbent assay ( ELISA) , and the hepatic histopathology was observed after HE staining. Results In DCP groups, the hepatic pathological changes of the mice were improved, the number of the inflammatory cells was reduced, and the activities of serum ALT, AST and AKP as well as the contents of hepatic TNF-α, IL-6 and NO were reduced ( P<0.05 or P<0.01 compared with those in the model group). Conclusion Dicliptera chinensis polysaccharide is effective for liver injury induced by antituberculosis drug, and the mechanism may be associated with its anti-inflammatory action.

Objective To prove the prophylactic function of absorbable gelatin sponge and bioprotein glue for prevention of epidural and nerve root scar adhesions after laminectomy. Methods We excised the L6 vertebral plates of 36 adult New Zealand male rabbits,to make vertebral plate excision model and to find nerve root. Then divided them into 3 groups based on different materials:gelatin sponge and bioproten glue (group A),gelatin sponge (group B) and saline solution (group C). The morphological changes of the scars were observed grossly and histologically at 2 and 8 weeks after operation. We also measured the orbit of the nerve root. Results Gelatin sponge combining with bioprotein glue can reduce adhesion obviously(P

Objective: To construct eukaryotic expression vector pSecTag2/HygroB-DAF of human decay accelerating factor (DAF) and transfect NIH/3T3 cells after encapsulated by chitosan. Methods:The human DAF fragments were obtained by PCR form DAF-pGEM-T Easy Vector, cloned into the eukaryotic expression vector pSecTag2/HygroB, and identified by restriction endonuclease’s digestion and DNA sequencing. After the particles of pSecTag2/HygroB-DAF were encapsulated by chitosan, the NIH/3T3 cells were transfected by chitosan-DAF nanoparticles and detected DAF expression by immunohistochemistry stain. Results:The DAF fragment was 1049 bp. Its sequence was as same as DAF cDNA in Genebank. After having been transfected by chitosan-DAF nanoparticles 24 hours, the NIH/3T3 cells showed diffusely positive in cytoplasms by anti-DAF immunohistochemistry. Conclusion:Eukaryotic expression vector of human DAF were constructed successfully and transfected it to NIH/3T3 cells after encapsulated by chitosan.
