The results showed that the combining therapy of methylprednisolone and methotrexate was effective for the patients with moderate-to-severe GO. Selenium supplement did not further improve the remission of GO.

Objective To investigate the treatment and prevention strategies of hematomas in operation area after anterior approach surgery for cervical spondylosis.Methods A retrospective review was conducted on 12 with hematoma compression in operation area out of 785 patients managed by anterior cervical surgery from January 2007 to July 2013,including 10 males and 2 females at age ranging from 40-71 years (mean 56.8 years).Surgery method was anterior cervical corpectomy and interbody fusion using titanium mesh cage plus plate and intraoperative blood loss was 300-1 200 ml.Primary clinical manifestations were neurological dysfunction in 5 patients,dyspnea in 6,and both neurological dysfunction and dyspnea in 1.There were 10 patients with the presence of symptoms at postoperative 0.5-22 hours,1 at postoperative 73 hours,and 1 at postoperative 74 hours.All the 12 patients underwent a second anterior cervical exploration.Results There were 5 patients with epidural hematoma,6 with subcutaneous hematoma,and 1 with both hematomas.After surgical interventions,the patients presented improvement in respiratory and neurological function,with inapparent respiratory abnormality and improved neurological function at discharge.One patient was died of cardiovascular-associated disease after being discharged from hospital.The left 11 patients were followed up for mean 19.8 months (range,6-43 months),with improved Japanese Orthopedic Association (JOA) score at final follow-up.Conclusions Hematoma took place frequently in the early period,especially within 24 hours in operation area after anterior approach to cervical disorders and close attention should be paid to respiratory and limb sensation and motion functions.Early detection and early surgical interventions are the key countermeasures to avoiding the severe results.

Objective To investigate the methods and effects of posterior fixation and fusion in treatment of complete thoracolumbar fracture and dislocation.Methods The study enrolled 8 cases of complete thoracolumbar fracture and dislocation treated by posterior fixation and fusion with pedicle screwrod system between January 2006 and December 2012.There were 7 males and 1 female,at mean age of 31.9 years (range,19-49 years).Mean time interval between injury and surgery was 8.1 days (range,4-12 days).Fracture-dislocation classification was AO type C,Denis three-column injury,and Meyerding grade V.According to American Spinal Injury Association (ASIA),there 5 cases at grades A,1 at grade B,1 at grade C 1 at grade E.Fracture-dislocation segments included T5-T6 in 1 case,T12-L1 in 3,L1-L2 in 2,L3-L4 in 1 and L4-L5 in 1.Results Mean duration of surgery was 220.6 minutes (range,135-335 minutes) and mean intraoperative blood loss was 1 150 ml (range,500-2 400 ml).Seven cases sustained dural laceration during the operation,which were sutured or covered with autologous fat grafts,but 3 of them were subjected to cerebrospinal fluid leakage and healed after conservative therapy.Anatomic reduction was achieved in 6 cases,partial reduction in 1 and non-reduction in 1.Mean Cobb angle improved from 29.3 ° (range,8 °-51 °) preoperatively to 1.9 ° (range,-5°-10 °) postoperatively.After a mean follow-up of 39.3 months (range,2-76 months),2 cases were recovered from preoperative ASIA grade A and B to C respectively and 6 cases (4 A,1 C,1 E) revealed no significant improvement.There was no implant loosening or breakage.One case was died of lung-related complications at postoperative 4 years.One case sustained lumbar deep infection at postoperative 3 weeks and managed by debridement,irrigation,drainage and implant retention.Conclusion Posterior fixation and fusion is the general treatment principle for complete thoracolumbar fracture and dislocation,but the degree of reduction depends on severity of the injured spinal cord.

Objective • To investigate the effect of V-set domain containing T cell activation inhibitor 1 (VTCN1) on long noncoding RNAs (lncRNAs) and mRNAs expression in colon cancer cells. Methods • VTCN1 was overexpressed by lentivirus plasmid in colon cancer cell line SW1116. RNA was extracted and sequenced. The differentially expressed lncRNAs and mRNAs were compared with the negative control group. The accuracy of RNA sequencing was verified by real-time quantitative PCR (qRT-PCR) using three differentially expressed lncRNAs and two mRNAs. BLAST2GO and Kyoto Encyclopedia of Genes and Genomes (KEGG) were used to analyze and predict the functions of these differentially expressed lncRNAs and mRNAs. The online platform GEPIA18 (Gene Expression Profiling Interactive Analysis) was used to analyze the correlation between differentially expressed lncRNAs and survival of patients with colorectal cancer. Results • A total of 167 differential genes, i.e., 39 lncRNAs and 128 mRNAs, were identified by RNA sequencing in VTCN1 overexpressed SW1116 cells. The results of qRT-PCR were consistent with those of RNA sequencing. Bioinformatics analysis showed that these different genes regulated by VTCN1 may be involved in endoplasmic reticulum protein processing and RNA monitoring signaling pathways. In addition, three lncRNAs (DNA JC9-AS1, HCG27, and RP11-339B21.13), which were significantly up-regulated in colorectal cancer cells overexpressing VTCN1, were also independent predictors of overall survival of colorectal cancer patients. Conclusion • In colon cancer cells, VTCN1 regulates several downstream lncRNAs and mRNAs, which may be involved in endoplasmic reticulum protein processing and mRNA monitoring signaling pathways.

Objective • To investigate the clinicopathological features, diagnosis and prognosis of rectal neuroendocrine neoplasms (R-NENs). Methods • The clinical data of 113 cases of R-NENs, from January 2008 to June 2017, were collected in Renji Hospital, Shanghai Jiao Tong University School of Medicine, and the clinicopathological features and prognostic factors were retrospectively analyzed. The expression of synapsin (Syn), neural cell adhesion molecule (CD56), and chromogranin A (CgA) were observed by immunohistochemistry in the R-NENs specimens. The specimens were also observed after hematoxylin-eosin staining. Results • In 113 cases of R-NENs, there were 59 males and 54 females, and their ages ranged from 25 to 83 with an average age of (52.3±13.3) years old. All the patients had no obvious clinical manifestations. The main symptoms included changes in bowel habits (21.3%), abdominal pain (8.9%) and anal symptoms (6.2 %), and 63.7% of cases were found in routine medical examinations. The R-NENs were diagnosed as G1 (79.6%), G2 (11.5%), and G3 (8.8%). Immunohistochemistry results demonstrated that 94.7% of tumors were positive for Syn, 80.9% for CD56, and 48.6% for CgA. Till November 2017, the median survival time was 33.10 months (0.40-114.67 months), with 1-year, 3-year, and 5-year survival rates of 93.8%, 90.0%, and 85.9%, respectively. The pathological grade, depth of tumor invasion, lymph node metastasis or distant metastasis, tumor size, and age were all associated with prognosis of patients with R-NENs. Conclusion • Most of R-NENs are low-grade malignant tumors with good overall prognosis and have a lack of specificity in clinical manifestations.

Multi-drug resistance is a major clinical challenge today. The good antibacterial effect of gold nanoparticles (AuNPs) based on their unique physical and chemical properties make such systems ideal for application as antibacterial drug carriers or self-modified therapeutic agents both in vitro and in vivo. AuNPs also have good clinical application prospects for their broad antibacterial spectrum, various antibacterial mechanisms and good biocompatibility. However, their structural stability in vivo, antibacterial mechanism, long-term safety and cytotoxicity of the surface modification have yet to be further explored and improved through subsequent studies.
