There has been increasing evidence that transcription of non-coding genome sequence is important to life:Relative to the protein coding sequence and a variety of small molecule RNA.IncRNA research is still only in its infancy.Its function and regulation need to be of further studied.In this paper,the current relationship between the tumor and the IncRNA is reviewed.IncRNA may provide new basis and targets for cancer diagnosis and treatment.

The suppressive effects of T. reglii on mouse cellular and humoral immune responses were studied. Lymphocyte proliferation effect induced with ConA,and PFC and OHS reactions with TD Ag(TNP-SRBC)were effectively suppressed by the drug. But the similar effects on LPS and TI Ag (TNP-SRBC) have not been found. The results shown that target cells of T. reglii effects may be T lymphocytes and the drug may not have a direct effect on B cells. The drug also shown a suppressive effect on IL-2 production by mouse spleen cells. The phenomenon suggests that the suppressive effects of T. reglii on humoral immune response may be indirectly mediated through suppressing helper T cells.

Glioma is an important cause of death in adults and children among the most common neural malignancies,with high morbidity and mortality in primary brain tumors.Despite advances in radiation and chemotherapy following surgical resection of the tumor,the median survival time of glioma remains poor.The effects of miR-21expression on tumor growth and invasion via regulating the pathways in human glioma cells,which regulate the expression of some small molecule.This review is mainly focused on the discovery of the correlation between microRNA-21 (miR-21) and glioma and the important role in the resistance of cancer cells to radiation and chemotherapeutic agents.

An enzyme linked immunosorbent assay ( ELISA ) and a flow cytometry assay ( FCA ) based on Wil2-S cells were developed and systematically compared for quantification of recombinant anti-CD20 humanized monoclonal antibody ( rh-anti-CD20zumab) in biological matrix. The specificity, precision and accuracy of each method at correspondingly different linear range showed good results. For ELISA, the precisions of intra-day and inter-day were both <19 . 5%, the relative error was from-18 . 2% to 17 . 6%;For FCA, the precisions of intra-day and inter-day were both <19. 0%, the relative error was from -18. 9% to 18. 4%. The sensitivity of ELISA was significantly higher than that of FCA. The quantitative ranges of ELISA and FCA methods were 0. 04-5. 0 mg/L and 3. 1-200 mg/L, respectively. The concentrations in serum samples and pharmacokinetics analysis were determined by both of two methods after vein drip administration of rh-anti-CD20zumab in rhesus monkeys. Pharmacokinetics data showed that there was excellent consistency between results obtained by two methods at the given dose. We believe that the novel FCA with high speed and high sensitivity can be used to perform PK and PD study of cell surface antigen-targeted antibody derivatives.

Objective To explore the differences of curative effect and short-term prognosis to severe traumatic brain injury patients with three different early postoperative nutritional supports.Methods A retrospective study was performed on 60 severe traumatic brain injury patients received in Neurosurgical Intensive Care Unit of Northern Jiangsu People's Hospital from July 2014 to July 2016.A total of 60 cases were randomly divided into the early enteral nutrition support therapy group,the early parenteral nutrition group,and the early compound nutrition group.The clinical indicators such as basic clinical characteristics before treatment,the nutrition data in two weeks,the length of stay in the Neurosurgical Intensive Care Unit,complications and GCS scores between the three groups were observed and analyzed.Results The indicators of early compound nutrition group were fasting blood-glucose (5.74 ± 0.64) mmol/L,prealbumin(203.80 ± 10.45) mg/L,total serum protein(61.99 ± 1.34) g/L,blood hemoglobin (114.53 ± 2.69) g/L,C-reactive protein(0.37 ± 0.06) mg/dl.The length of stay in Neurosurgical Intensive Care Unit was (11.6 ± 0.42) days in the compound nutrition group while those in the early enteral nutrition group was (13.20 ±0.42) days and those in the early parenteral nutrition group was(14.65 ± 0.42) days.The postoperative complications of the compound nutrition group were significantly lower than other two groups.The GCS scores of early compound nutrition group was(11.40 ± 1.60),which was the best in three groups.The differences were statistically significant (P ＜ 0.05).Conclusions Early compound nutrition support has an exact curative effect on postoperative severe traumatic brain injury patients in Neurosurgical Intensive Care Unit.It can obviously improve the nutrition status of patients with less complications,shorter length of stay in Neurosurgical Intensive Care Unit,higher safety and lower degree of coma,worth clinical promotion.

Objective To investigate the magnetic resonance imaging (MRI) and computerized tomography (CT) imaging findings of hepatic angiomyolipoma (AML).Methods Twelve cases of hepatic AML,which were confirmed by pathologists between 2009 and 2011 in our hospital,were retrospectively analyzed.Results There were 3 males and 9 females with an average age of 44.17 years (range,34 to 60 years).There were 14 lesions,8 in left lobe,6 in right lobe.All of 12 cases were confirmed as angiomyolipoma by pathologists.Nine cases were performed with MRI,2 with CT,and 1 with both CT and MRI.The border of lesions were clear in 8 cases.Fat contents were shown on CT and/or MRI in 8 cases.After administrated with contrast medium,the lesion enhancement was still apparent or slightly decreased in 9 lesions from portal phase to delayed phase.The suppression of portal vein and inferior vena cava by tumor were seen in 5 lesions.Abnormal vascular distortion was seen in 6 lesions.None of 12 lesions were found with portal vein thrombosis.Conclusion The diagnosis of hepatic angiomyolipoma should be considered when CT and MRI show good boundaries,intratumoral fat content,delayed lesion enhancement,and vascular distortion.

Objective To construct a lentiviral vector containing mir-7-3 gene and green fluorescent protein (GFP) gene,and to detect the expression of mir-7-3 gene in U251 cells.Methods The fragments containing all the mir-7-3 gene were amplified by RT-PCR and were cloned into the lentivirus vectors labeled with GFP,which was transfected together with the packaging plasmids into 293T cells by CaC12.The supernatant was collected,concentrated,identified,and was transfected to U251 cells of gliomas.Fluorescent microscopy was used to observe the fluorescence in the 293T cell,and real time RT-PCR was used to examine the relative contents of mir-7-3 in U251 cells.Results Electrophores was shown that the sequence of the RT-PCR product was consistent with the data of mir-7-3 by DNA sequence analysis,indicating that the mir-7-3 gene was successfully cloned,and strong green fluorescence was observed by fluorescent microscopy.The supernatant of lentivirus-transfected 293T cells effectively infected U251 cells and the relative content of mir-7-3 was observed in the transfected U251 cells.Conclusion It is concluded that the lentiviral vector containing mir-7-3 gene was constructed successfully,which provides a basis for further study of mir-7-3 function.

Objective To investigate the value of bispectral index and intracranial pressure monitoring in evaluation of postoperative consciousness and short-term prognosis in patients with severe traumatic brain injury.Methods A simple random sampling method was used in 30 cases of brain trauma coma patients in the People's Hospital of Northern Jiangsu Province from January 2014 to December 2014.Glasgow coma scale (GCS) were evaluated at intervals of 8 hours,GCS were recorded for 3 days after surgery,The bispectral index value and intracranial pressure value are recorded at the same time.According to GCS,the patients were divided into two groups,group A (3≤GCS≤5) and group B(5 ＜ GCS≤8).The 21-days natural survival rate was counted.The Kaplan-Meier Method and Log-rank test were used to analyze the relationship between Bispectral index and intracranial pressure.Results The bispectral index value of group A was 45.3 ± 3.8,the intracranial pressure value of group A was (18.6 ± 2.8) mmHg,The bispectral index value of group B was 32.2 ± 8.2,the intracranial pressure value of group B was (33.4 ±4.6) mmHg.The 21-days survival rate of group A was 55％,and 21-days survival rate of group B was 30％.The Spearman rank correlation method was used to analyze the values.Bispectral index value was positively correlated with coma degree after operation in patients with severe traumatic brain injury,and was negatively correlated with intracranial pressure value (r =0.532,P ＜ 0.05;r =0.521,P ＜ 0.05).The more severer the patient's craniocerebral injury.,the more severer the condition,the higher the intracranial pressure,the lower the bispectral index value,the worse the prognosis is.Conclusion Combined monitoring of bispectral index and intracranial pressure has high application value in evaluating the coma degree and prognosis of patients with severe craniocerebral injury after operation.
