BACKGROUND: Schwann cells play an important role in axonal growth and myelin sheath formation of the peripheral nerve. Whether Schwann cells play the same role in the spinal cord had attracted considerable attention. Microencapsulation technology as an effective immune isolation technique can effectively keep Schwann cell activity to play the repair effect of Schwann cell in the spinal cord.OBJECTIVE: To observe the changes of myelin sheath in the injured transection of rats after transplantation of the alginic acid microencapsulated Schwann cells.DESIGN, TIME AND SETTING: The randomized controlled animal experiment was performed at the Basic Medical School of Nanchang University from March 2005 to February 2008.MATERIALS: Sciatic nerve trunk was obtained from adult rabbits to harvest Schwann cells in vitro using repeatedly differential velocity adherent technique, and to prepare Schwann cell suspension and microencapsulated Schwann cell suspension.METHODS: A total of 146 adult Sprague Dawley rats were used to establish models of right hemi-transection damage at T_(10) level and randomly assigned to four groups: simple injury group (n=44), cell transplantation group (n=44), microencapsulated cell transplantation group (n=44) and normal control group (n=14). At 1, 3, 7,14 and 28 days following surgery, 8 rats were selected from each group at each time point (2 from the normal control group) for perfusion and fixation. Spinal cord tissue was collected to make paraffin section, and then subjected to hematoxylin-eosin staining and Loyez myelin staining. In addition, 2 rats were selected from each group at 2 and 8 weeks. The spinal cord tissue was fixed, embedded in Epon816, stained using uranyl acetate and aluminum citrate, and then observed using an electron microscope.MAIN OUTCOME MEASURES: Neuron number and survival were observed surrounding the damaged region. Structural changes in the myelin sheath from spinal cord white substance at the damage site were measured.RESULTS: At 1 and 3 days following spinal cord injury, spinal neurons were degenerated and necrotic at damaged site, with reduced number of myelin sheath, loose structure, but above-mentioned was rare in the cell transplantation and microencapsulated cell transplantation groups. At 7 days, the reduced number of myelin sheath, with damaged structure was seen. The microencapsulated cell transplantation group was light. At 14 days, number of neurons was increased, with increased cell body, especially in the microencapsulated cell transplantation group. At 28 days, neurons gradually recovered, myelin sheath was gradually complete, with increased number in the microencapsulated cell transplantation group. There were significant differences compared with the simple injury and cell transplantation groups (P < 0.01). At 8 weeks, abundant myelin sheath was repaired, with new myelin sheath in the microencapsulated cell transplantation group.CONCLUSION: Microcapsule has immune isolation effects. Microencapsulated rabbit Schwann cells can promote the repair of rat spinal cord neurons and axonal myelinization.

Objective To investigate the effect of HCV RNA on virological and immunological response to highly active antiretroviral therapy (HAART),liver function and blood lipid levels in HIV/HCV co-infected patients.Methods In a cohort study,275 HIV/HCV co-infected former blood donors receiving HAART were followed up every six month in Henan province in China.HCV RNA,HIV RNA,CD+4 T cell counts,indexes of liver function and lipid levels were periodically tested.The differences of HIV viral load suppression,immunological response,liver injury and blood lipid levels between HCV RNA positive group and negative group were compared by x2 test and two independent-samples tests.Result There was no significant difference of HIV viral load suppression between HCV RNA positive group and HCV RNA negative group six-month treatment (45.6% vs.38.5% ,X2=1.150,P>0.05) and CD+4 T cell counts before (286 cells/μ1 vs.209 cells/μ1,Z=0.734,P=0.463)and after 6-month (310 cells/μ1 vs.362 cells/μl,Z=0.562,P=0.574) ,12-month(378 cells/μ1 vs.289 cells/μ1,Z=1.091,P=0.275),18-month(363 cells/μ1 vs.288 cells/μl,Z=1.435,P=0.151) ,24-month(413 cells/μ1 vs.348 cells/μ1,Z=0.939,P=0.348) HAART.The mean levels of serum ALT (55.0 U/L vs.29.5 U/L,Z=6.789,P<0.01),AST(46.0 U/L vs.33.0 U/L,Z=4.890,P<0.01)、TBIL(9.3 mmol/L vs.7.2 mmol/L,Z=3.748,P<0.01)were significantly higher in HCV RNA positive group than that in HCV RNA negative group.HCV RNA was the independent variables associated with liver injury after HAART (aOR=3.8,P<0.01).The serum triglyceride level was higher in HCV RNA positive group than that in HCV RNA negative group(1.2 mmoL/L vs.1.4 mmol/L,Z=1.936,P=0.043) .The serum HDL level was higher in HCV RNA positive group than that in HCV RNA negative group (1.5 mmol/L vs.1.3 mmol/L,Z=2.251,P=0.024).Conclusions HCV RNA does not affect HIV virological responses to HAART and CD+4 T recovery.HCV RNA is an independent risk factor associated with liver injury in HIV/HCV co-infected patients receiving HAART,but appears to provide significant protection against HAART-ieduced hyperlipidemia.

Objective To investigate the effects of long non-coding RNA 00894(LINC00894)gene on prolifera-tion and metastasis of human gastric cancer cells,and to verify the regulatory relationship of LINC00894,miR-205-5p and ZEB1 in gastric cancer.Methods The expression level of LINC00894 in gastric cancer cell lines,normal gastric lines,clinical gastric cancer and normal gastric tissue samples were determined by RT-qPCR.Through fol-low-up,the relationship between the expression level of LINC00894 and the prognosis of gastric cancer patients was explored.LINC00894 knockdown cell lines and overexpression cell lines were constructed,and the knockdown and overexpression efficiency was detected by RT-qPCR.Cell proliferation and metastatic capacity were determined by CCK 8,clone formation and Transwell assays.Dual-luciferase reporter assays,RT-qPCR assays and Western blot assays were used to examine the targeted regulatory relationships of LINC00894,miR-205-5p and ZEB1.Results The expression of LINC00894 gene in gastric cancer tissues or cells was significantly higher than that in normal gas-tric tissues or cells,moreover,gastric cancer patients with high LINC00894 gene expression had a worse prognosis.The knockdown of LINC00894 inhibited the viability,clonogenesis,migration and invasion ability of gastric cancer cells,and conversely,the overexpression of LINC00894 obtained the opposite results.LINC00894 promoted ZEB1 expression by targeted downregulation of miR-205-5p expression.LINC00894 promoted the expression of ZEB1 by targeting miR-205-5p and down-regulating its expression.Conclusion LINC00894 serves as an oncogene in gastric cancer and may promote proliferation and metastasis of gastric cancer cells via regulating miR-205-5p/ZEB1 axis.

Objective To evaluate the effect of intrathecal oxytocin on neuropathic pain in rats.Methods Thirty-six SPF male Sprague-Dawley rats,aged 4-6 weeks,weighing 100-150 g,were divided into 4 groups (n =9 each) using a random number table:control group (group C),neuropathic pain group (group NP),neuropathic pain plus normal saline group (group NPN) and neuropathic pain plus oxytocin group (group NPO).The neuropathic pain model was made by partial sciatic nerve injury in NP,NPN and NPO groups.In group NPO,oxytocin l0 μl (0.1 μg) was intrathecally injected on the day of establishing the model and 1 and 2 days after establishing the model,and then normal saline 10 μl was given for tube sealing at 9 a.m.and 4 p.m.every day.In group NPN,normal saline 20 μl was given for tube sealing at the corresponding time points.The mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured at 1 day before establishing the model and 1,2,3,4,5,6 and 7 days after establishing the model.The expression of the astrocyte marker glial fibrillary acidic protein (GFAP) and a specific marker of microglia ionized calcium-binding adaptor molecule 1 (IBa-1) was detected by Western blot at 1 day before establishing the model and 3 and 7 days after establishing the model.Results Compared with group C,the MWT was significantly decreased,TWL was shortened and the expression of GFAP and IBa-1 was up-regulated at each time point in NP and NPN groups (P＜0.05).There was no significant difference in MWT,TWL GFAP and IBa-1 at each time point between group NPN and group NP (P＞0.05).Compared with NP group,MWT was significantly increased at 2-4 days after establishing the model,TWL was prolonged at 1-4 days after establishing the model,the expression of IBa-1 was down-regulated on 3 days after establishing the model,and the expression of GFAP was downregulated on 3 and 7 days after establishing the model in group NPO (P＜0.05).Conclusion Oxytocin can reduce neuropathic pain,and the mechanism may be related to inhibiting activation of glial cells in the spinal cord of rats.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.
