Schwann cells (SCs) have potently neuroprotective and myelinization abilities. They are one of the earliest and the most frequently used cells that are applied to therapeutic studies in spinal cord injury. At present, SCs are usually used as a platform for therapeutic alliance to integrate various interventions. This review will mainly discuss the issues met in therapeutic alliances with SCs for spinal cord injuries, results of various therapeutic alliances with SCs, positive effects of co-transplantation with SCs on neural stem cells, survival, migration of SCs after transplantation and roles of endogenetic SCs in repairing spinal cord injury.

Objective To observe the effect of Yishen Paizhuo Decoction(Decoction for reinforcing the kidney and discharging the turbid)on chronic renal failure(CRF)patients.Methods The 82 CRF patients were randomized into observation group(42 cases) and control group(40 cases).In addition to the routine treatment,the observation group was administered modified Yishen Paizbuo Decoction,and the control group was given coated aldehyde oxystarch.The course of treatment was 6 months for both groups. Changes of clinical symptoms,renal functions,blood fat,and hemoglobin were observed,and the linear regression evaluation and renal survival evaluation were employed to evaluate the development of CRF.Results The improvement of observation group in renal func- tions and blood fat was remarkable with the increased renal survival rate,compared with the control group,the difference was signifi- cant(P

Objective To explore the relationship of the ADAM33 gene Q-1,T2 single nucleotide polymorphism (SNP) and suffering from chronic obstructive pulmonary disease (COPD) in Xinjiang Kazakh and Han population. Methods Peripheral blood samples to extract DNA, and the single nucleotide polymorphisms of Q-1 and T2 in ADAM33 gene were detected by SNaPshot SNP genotyping. Results Case group compared with the control group, frequencies of Q-1 locus genotypes and alleles were significant differences in Kazak (P<0.05). In patient group, there were significant differences in ADAM33 gene Q-1 locus genotypes FEV1% predicted, FEV1/FVC of clinical indicators lung function in Kazak, Han(P < 0.05). Kazak Q-1 locus AA genotype,Han GA genotype than GG genotype were significant difference.Compare Kazak AA genotype,Han GA genotype with GG genotype is more likely to cause COPD in Q-1 locus(P<0.05). In the comparison of the case and control group the two ethnic, there was no significant difference between the frequencies of T2 locus genotypes and the frequencies of Q-1,T2 the alleles (P > 0.05). There were no significant differences in T2 locus genotypes and clinical indicators of lung function FEV1% predicted and FEV1/FVC in patient group (P > 0.05). Conclusion The ADAM33 gene Q-1 locus may be related to the COPD susceptibility in Xinjiang Kazak, Han.

Immortalized human precartilaginous stem cells (IPSCs) were established to provide stable cell resource for the study of the molecular mechanism of gene targeting on the differentiation of PSCs. Plasmid pCMVSV40T/PUR containing simian virus 40 large T antigen gene (SV40Tag) was transfected into human PSCs by using lipofectin transfection. Colonies were isolated by puromycin selection and expanded by multiple passages. Immunohistochemistry, RT-PCR and Southern blotting were used to identify the transfected cells and to detect the expression and integration of SV40Tag in expanded cell lines. The positive colonies were isolated and subcultured, designated immortalized precartilaginous stem cells (IPSCs), which were confirmed as fibroblast growth factor receptor-3 (FGFR-3) positive cells by immunohistochemistry and RT-PCR. SV40Tag cDNA was found in cultured IPSCs of passage 8 by Southern blotting, and the expressions of SV40Tag mRNA and protein were confirmed by RT-PCR. These findings suggested that IPSCs strain with SV40Tag was constructed successfully.

Objective To investigate the effect of TanshinoneⅡA on nerve conduction of oxaliplatin induced peripheral neuropathy in rats. Methods Fifty Wistar rats were randomly divided into normal control group, model group, treatment group, prevention group, prevention and treatment group. Except for those in model group, Wistar rats were injected i.p. with oxaliplatin (20 mg/kg). The electrophysiological instrument were employed to detect the sciatic nerve conduction velocity, latency, amplitude 6 h, 24 h, 72 h and 7 d after modeling. Results In the model group, velocity of sciatic nerve conduction slowed, and latency prolonged 24 h after modeling (P<0.05) which continued to slow and prolong until 7 d after modeling (P<0.05). After the application of Tanshinone ⅡA, nerve conduction velocity became faster and latency shorter significantly (P <0.05), especially in the prevention and treatment group, in which no significant difference was found when compared with those in the normal control group (P > 0.05). Conclusions During the chemotherapy with oxaliplatin , TanshinoneⅡA can increase the conduction velocity of sciatic nerve , shorten the disease duration and play a protective role for peripheral nerve.

In 2013 Shanghai took the lead to carry out the specialist standardized training which is common in the international medical education. This paper first gives a picture of the general condition of the standardized training on specialists of obstetrics and gynecology in Shanghai. Then from the perspectives of strategic deployment, department management, clinical skill training and the training of examiners, the paper explores the assessment model in which both the assessment of train-ing process and the scores of the final examination are considered whereas the process assessment is given more weight. This paper is aimed to provide experience and suggestions for the further advance of the specialists standardized training in the field of obstetrics and gynecology.

Dermatology and venerology is a clinical discipline characterized by morphology.With the development of the internet and the application of internet in education,the features and advantages of internet teaching are gradually recognized including high flexibility,rich information and good student-teacher interaction.This article focused on the establishment and practice of internet teaching to improve teaching quality.

Objective To evaluate tumor angiogenesis and clinical significance by contrast-enhanced CT in case of non-small cell lung cancer (NSCLC). Methods 30 patients with NSCLC underwent dynamic thoracic CT, and histopathological slides were carefully prepared for VEGF immunohistochemical staining. Maxium attenuations of dynamic CT were compared with VEGF expression levels and lymph-node metastases. Results The mean peak attentation was (36.28?6.41)HU, VEGF positive expressions were in 21 patients, and negative expressions were in 9 patients. VEGF expression levels in patients with NSCLC stage II and III were higher than those in stage I , and in lymph node metastases group, the expression levels of VEGF were also higher than those in non-metastatic nodes. CT enhancement of NSCLC was positively related to VEGF expression,neoplasm stage and lymph-node metastases. Conclusion CT enhancement of NSCLC can reflect tumor angiogenesis and correlate to lymph-node metastases closely, help lung cancer diagnoses,neoplasm stage, and serve as a supplement to the present staging system for lung cancer in biological behavior.
