microRNAs (miRNAs)are endogenous non-coding RNAs,which play important roles in the regulation of gene terms.miRNAs affect almost every physiological process of the body,and many diseases are related to the disorders of miRNAs.Current studies show that the abnormal expressions of miRNAs are closely relate to the tumorigenesis,diagnosis,treatment and prognosis of gastric cancer.So miRNAs can be used as potential biomarkers and therapeutic targets for the gastric cancer.

Objective To analyze the rented factors leading to successful treatment of ectopic pregnancy by conservative therapy and to explore importance of this therapy. Methods 152 patients with ectopic pregnancy performed with conservative treatment were randomly recruited into a methotrexate plus Chinese medicine group, a 5-fluorouracil plus Chinese medicine group and a exclusive Chinese medicine group. The curative rate and side effect were observed in groups, and the relation between the treatment condition and the curative rate was analyzed. Results There was no difference in curative rate among groups, while the side effect in the exclusive Chinese medicine group was lower than other groups. It showed high curative rate in patients with two or more conditions of having mass less than 3 cm, the level of bloodβ-hCG less than 1000 IU/L, and the depth of posterior fomix effusion less than 1 cm. Conclusion Among the treatments of ectopic pregnancy, Chinese medicine has fewer side effects. Fully evaluation on the treatment condition can improve the curative rate.

Objective To test the reliability and validity of the brief International Classification of Functioning, Disability and Health (ICF) core sets for Chinese stroke patients using Rasch model analysis. Methods The body functions of 38 Chinese stroke patients were measured using the brief ICF core sets. The qualifiers of the 20items were measured by two raters and analyzed using FACETS statistical software. The intra-rater reliability and validity were tested by using the separation index and separation reliability and fit analysis. Results The brief ICF core sets had good internal consistency and reliability (person separation index = 6.02, person separation reliability = 0.94 ) with these Chinese patients. The raters showed significantly different strictness in rating, but their ratings had good internal self-consistency. The construct validity was good for the body functions of the ICF component ( separation index = 10.50, separation reliability = 0.80) , but misfitting and overfitting were found in items b117, b152and b755. Conclusion The body function of the brief ICF core sets has good reliability and validity for Chinese stroke patients. A many-facet Rasch measurement model can provide comprehensive information and has good application prospects for testing the reliability and validity of ICF core sets.

AIM:To evaluate the availability and our experience of intraoperative image-guidance in endoscopic nasocular operation.METHODS:Seven cases of endoscopic nasal surgery with intraoperative image-guidance were retropectively reviewed,including 3 cases of optic nerve injury;3 cases of foreign object of optic behind the eyeball;1 case of retrobulbar tumor(angeioma).RESULTS:The preoperative preparatory time would take 15 minutes,including coordination,head holder localization,conventional instrument registration.In our cases,the localization accuracy between 3-D image landmarks of navigation system and actual anatomical landmarks was less than 1.3mm.The optic nerve and other anatomical points could be orientated accurately in intraoperative procedures.No complication occurred.CONCLUSION:Nasal endoscope combined with imageguidance systems provides accurate anatomical localization of anterior skull base with enlarged operation field.It is possible for surgeons to observe important anatomical structures during endoscopic surgery.It could increase the effectiveness and decrease surgical complications,especially in complicated cases.

Objective To identify International Classification of Functioning,Disability and Health (ICF) core categories most applicable to patients with dysphagia.Methods Swallowing dysfunction rating scales were searched through Embase,MEDLINE and CNKI covering the period between August 2005 and August 2015.All the scales found were classified and matched with different dimensions of the ICF so as to select the most applicable core sets.Results A total of 57 ICF items were included in the core set designed for dysphagia,including 27 body function items,13 body structure items,7 activity and participation items and 10 environmental factor items.Conclusions The ICF core categories selected for dysphagia through this systematic review provide a more comprehensive framework for future assessment and treatment of dysphagia.

Objective To investigate clinical signifieances of serum levels of vascular endothelial growth factor (VEGF) in patients with diffuse large B-cell lymphoma (DLBCL) and to analyze the relationships with international prognostic index (IPI). Methods Serum levels of VEGF were measured by ELISA in 26 cases with newly diagnosed DLBCL and 9 cases with relapsed DLBCL. The clinical data of 26 patients were collected. According to the IPI, 26 patients were divided into two group: low risk group (IPI＜2) and moderate to high risk group (IPI≥2). Results Compared with the normal controls, newly diagnosed and relapsed DLBCL had significantly higher VEGF serum levels (P ＜0.01). In the patients responding to CHOP or RCHOP regimen a significantly decrease in VEGF serum levels occurred, while in the patients who did not achieve complete remission(CR) there was no significant decrease. Furthermore, pretreatment serum levels of VEGF were significantly lower in CR group than in partial remission (PR) and no remission (NR) group. In addition, serum levels of VEGF were significantly elevated in the high risk group than those at the low risk group(P＜0.01). Conclusion The serum levels of angiogenic factor VEGF are related to the development and progression of DLBCL. The VEGF combined with IPI can be used for evaluating the prognosis of DLBCL.

Objective To screen and identify International Classification of Functioning,Disability and Health (ICF) core sets for spasticity and make a dedicated and comprehensive assessment tool for spasticity after stroke.MethodsFifty patients with spasticity after stroke were involved in this study.Information about them was collected by clinical investigation and self-completed questionnaires.The ICF scale was used to assess the severity of each item.Each item's frequency was calculated and those items with frequencies ≥ 30％ were selected as the first ICF core set for spasticity.The ICF check list was designed as a questionnaire and 8 doctors and 5 therapists were consulted.Items with frequency ≥50％ were chosen as the second level ICF core set for spasticity.The two results (termed ICF core sets Ⅰ and Ⅱ) were integrated with the initial ICF core sets for spasticity and sent to 42 experts in the area of neurological rehabilitation.Items with a frequency ≥80％ were chosen as the final ICF core set for spasticity.ResultsA total of 32 ICF items were included in the ICF core set for spasticity after stroke.There were 10body function items,4 body structure items,13 activity and participation items and 5 environmental items involved.ConclusionThe ICF core set for spasticity was identified in this study.The selected items covered content broader than other common spasm assessment scales.The result is a comprehensive description of spasticity.

Objective: To construct eukaryotic expression vector pSecTag2/HygroB-DAF of human decay accelerating factor (DAF) and transfect NIH/3T3 cells after encapsulated by chitosan. Methods:The human DAF fragments were obtained by PCR form DAF-pGEM-T Easy Vector, cloned into the eukaryotic expression vector pSecTag2/HygroB, and identified by restriction endonuclease’s digestion and DNA sequencing. After the particles of pSecTag2/HygroB-DAF were encapsulated by chitosan, the NIH/3T3 cells were transfected by chitosan-DAF nanoparticles and detected DAF expression by immunohistochemistry stain. Results:The DAF fragment was 1049 bp. Its sequence was as same as DAF cDNA in Genebank. After having been transfected by chitosan-DAF nanoparticles 24 hours, the NIH/3T3 cells showed diffusely positive in cytoplasms by anti-DAF immunohistochemistry. Conclusion:Eukaryotic expression vector of human DAF were constructed successfully and transfected it to NIH/3T3 cells after encapsulated by chitosan.
