Objective To explore the effect of peripheral nerve electrical stimulation on axon regeneration after spinal cord injury (SCI) in rats. Methods Nighty-two healthy Sprague-Dawley rats were randomly divided into blank control group (n=12), control group (n=40) and experimental group (n=40). All groups were suffered NYU impaction to prepare T8 SCI models, the control group and the experimental group implanted stimulating electrode on the sciatica nerve. The experimental group received electric intervention in addition. They were evaluated with BBB score one day, one week, two weeks, four weeks and eight weeks after modeling; and with motor evoked potentials (MEP) one week, two weeks, four weeks and eight weeks after modeling. Morphological changes and the expression of neurofilament pro-tein (NF)-200 and glial fibers acid protein (GFAP) were observed by HE staining and immunohistochemistry one week, two weeks, four weeks and eight weeks after modeling. Results There was no significant difference in BBB scores among three groups (P>0.05) in all the time points except eight weeks (P<0.05). There was no significant difference in the amplitudes and latencies among three groups one week after modeling (P>0.05), however, there was significant difference two weeks, four weeks and eight weeks after modeling (P<0.05). All the groups showed syringomyelia and glial scar formation one week, two weeks, four weeks and eight weeks after modeling. There was no sig-nificant difference in NF-200 axon count among three groups one week after modeling (P>0.05), but was different two weeks, four weeks and eight weeks after modeling (P<0.05). There was no significant difference in GFAP area count among three groups in all the time points (P>0.05). Conclusion Implantable peripheral nerve electrical stimulation can improve conduction function and motor function in rats with SCI. And it may promote axonal regeneration of the injured segments.

Objective To observe and analyze the therapeutic effect of focal uterine adenomyosis treated with percutaneous microwave ablation by contrast-enhanced ultrasound and dynamic contrast enhanced MRI (DCE-MRI).Methods From January 2013 to July 2016,42 patients with focal uterine adenomyosis voluntarily underwent percutaneous microwave ablation in the tumor hospital of Liaocheng.Contrast-enhanced ultrasound and DCE-MRI were performed before and after percutaneous microwave ablation.The therapeutic effects of percutaneous microwave ablation in treatment of uterine adenomyosis lesions were observed.Results After percutaneous microwave ablation of the 42 cases,the ablated zone showed no enhancement with contrast-enhanced ultrasound and DCE-MRI.Contrast-enhanced ultrasound showed that the volume and ablation rate of ablated zone were (49.0±29.5) cm3 and (91.6± 7.1)％,and that of DCE-MRI were (49.4 ± 29.9)cm3 and (91.9 ± 6.7)％,respectively.The results showed that percutaneous microwave ablation could cure focal uterine adenomyosis at the rate over 90％.Contrast-enhanced ultrasoundand DCE-MRI are in accordance in observing the ablation rate.Conclusions Contrast-enhanced ultrasound can accurately show the ablation rate of focal uterine adenomyosis treated with percutaneous microwave ablation,which is quite consistent with DCE-MRI.Contrast-enhanced ultrasound has its advantages such as identifying the lesions which need immiedately supplemental ablation.

Objective To analyze and evaluate neoadjuvant chemotherapy's value and significance in combining with surgical treatment for limited small cell lung cancer(LD-SCLC).Methods A total of 94 LD-SCLC patients underwent complete resections combined with chemotherapy between January 2000 and January 2011 in Shanghai Pulmonary Hospital.Among these cases,initial two cycles of neoadjuvant chemotherapies were performed for all pathologically confirmed patients (Group A),and initial operations followed by adjuvant chemotherapy were administered to patients without pathology (Group B).The survival rate was analyzed by log-rank test and Kaplan-Meier method.Multivariate analysis of the prognostic factors was performed using Cox's regression model.Results Group A included 43 cases and Group B included 51 cases.The mean age was (56.37 ± 10.18) years.According to the 6th edition of Tumor,Node,Metastasis(TNM) classification of lung cancer,54 cases were at stage Ⅰ or Ⅱ,40 cases were at stage Ⅲ.Overall 5-year survival(5-YS) was 27％.The 5-YS for patients with stage Ⅰ-Ⅱ was notably better than that of stage Ⅲ (34％ vs 20％,P =0.033).For patients with stage Ⅲ,the 5-YS of Group A was significantly better than that of Group B(34％ vs 12％,P =0.020),besides median overall survival for Group A and Group B were 46 and 15 months(P =0.009).Furthermore,the results of multivariate analysis showed that neoadjuvant chemotherapy,surgery and histopathology of SCLC were independent factors that strongly affected survival and prognosis.Conclusion In combined surgical treatment for LD-SCLC,neoadjuvant chemotherapy obviously improved the prognosis of patients with stage Ⅲ.Therefore,it was very important and necessary that pre-surgical neoadjuvant chemotherapy was administered to resectable stage Ⅲ LD-SCLC patients.
