Cervical artificial disc replacement (CADR) as a new method for the treatment of cervical spondylosis, is becoming a basic and clinical research. Compared with the anterior cervical discectomy and fusion (ACDF), the biggest difference of CADR lies in the reconstruction of the cervical vertebra height and physiological curvature, retaining the spinal physiological function maximally and reducing the degenerative changes in adjacent segments. A large number of clinical investigation have suggested that ACDR can become an operation method to replace the ACDF. However, the complications and the problems of prosthesis itself are gradually exposed, such as that the prosthesis, can't completely simulate the biological effects of human intervertebral disc, the other factors and including the operation methods and prosthesis itself. At the same time, the problem that how to prevent complications and problems is required to be solved. Whether, the effect of CADR on the activity of the operation segment, and the prevention of adjacent segment degeneration can be guaranteed for a long time has drawn more and more attention from scholars.

Objective To investigate Bcl-2 expression in the peripheral blood mononuclear cells and its clinical significance of liver fibrosis (LF). Methods Tested Bcl-2 protein levels in T, B cells of 47 patients (male 17, female 30) with LF, 35 patients (male 24, female 11) with chronic hepatitis B and no LF and 41 cases (male 29, female 12) normal controls by two color cytofluorography. Results Among them, LF patients, chronic hepatitis B without LF and normal controls, the proposition of T cells (including CD3~+, CD4~+ and CD8~+ subgroups) and CD19~+ B cells expressed Bcl-2 protein increased significantly in LF patients (P

Lung cancer has the highest morbidity and mortality rate among malignant tumors. Early diagnosis and effective treat-ment are the keys to improving the survival of lung cancer patients. A type of endogenous, highly conserved, non-coding small mole-cule RNA (i.e., miRNA) was found to play an important role in the occurrence and development of this disease. Research on this molec-ular marker miRNA for the diagnosis, treatment and prognosis of lung cancer has rapidly progressed. This paper reviews the research work on miRNA as a molecular marker in the early diagnosis, treatment efficacy, and prognosis of lung cancer and explores some ques-tions related to this disease.

Objective This report investigate the intervention effect of the water extract of Alpinia oxyphylla Miq. fruit (AOF)on memory impairment and the mechanism in cerebral ischemia rats. Methods 48 Rats were randomly divided into sham-operated group(n=12), ischemia group(n=12), AOF group Ⅰ( n= 12)and AOF group Ⅱ (n= 12). The model of transient cerebral ischemic/reperfusion was made by bilateral occlusion of common carotid arteries in rats and combination with reducing blood pressure with an abdominal injection of so-dium nitroprusside. Learning-memory ability was observed by step through test. The content of NO and the activi-ties of NOS were measured in hippocampus. Results In step through test,the latency in ischemia group[(143.8±65.2)s]significantly decreased, the number of errors (8.9±4.2 ) significantly increased compared with sham-operated group [latency: (257.2±67.1 ) s; number of errors: (1.7±1.1 ), P<0.01 ]. The latency in AOF group Ⅰ and AOF group Ⅱ[(186.5±46.2) s, (193.4±43.7 ) s ] significantly increased, the number of errors (6.1±2.9,5.2±2.1 ) significantly decreased compared with ischemia group(P<0.05, P<0.01). In hippocampus, the content of NO and the activities of NOS in ischemia group [(56.53±27.42) nmol/mg prot, (17.23±5.64) nmol/mg prot] significantly increased compared with sham-operated group[ (40.02±17.9 ) nmol/mg prot, ( 10.46±6.15)nmol/mg prot], and in AOF group Ⅰ and AOF group Ⅱ [content of NO:group Ⅰ (46.60 ±20. 26)nmol/mg prot,group Ⅱ (42.38±21.23) nmol/mg prot ;activities of NOS:group Ⅰ (13.98±5.13 ) nmol/mg pint,group Ⅱ(13.61±5.27) nmol/mg prot] significantly decreased compared with ischemia group(P<0.05). Conclu-sion AOF could significantly ameliorate the memory impairment in cerebral ischemic rats. Its effects may be in-volved in the decrease of content of NO and activities of NOS in hippocampus.

Objective To investigate the expression of programmed cell death-1(PD-1)ligands on HepG2 cell and 2.2.15 cell.Methods Culture HepG2 cell and 2.2.15 cell in vitro and stain the cells with fluorescence-labeled monoclonal antibodies specifically against PD-L1 and PD-L2,respectively.Isolate total RNA of HepG2 cell and 2.2.15 cell and detect the mRNA expressions of PD-L1 and PD-L2 by RT-PCR.Results The expression of PD-L1 on 2.2.15 cell was upregulated on the levels of both proteins and mRNA.The expression of PD-L2 in 2.2.15 cell was not detected.And neither the PD-L1 nor PD-L2 was detected in HepG2 cell.Conclusion HBV infection can upregulate the expression of PD-L1 on hepatocyte,which might contribute to the immune evasion of HBV.

ObjectiveTo evaluate the feasibility of detecting the mutations of KRAS,EGFR in nonsmall-cell lung cancer and colorectal cancer patients with high resolution melting curve analysis. MethodsAt first,the mutations in KRAS exon 2 and EGFR exons 18 to 21 of 5 patients with non-small cell lung cancer and 5 patients with colorectal cancer were detected by high resolution melting curve analysis.Then the results were confirmed with direct sequencing. ResultsBy high resolution melting curve analysis,1 of 10 patients was found to carry EGFR 19 mutation who was harboring 2236-2250del mutation.By direct sequencing,consistent results of the patients with mutations orwithout mutations were got. Conclusion s The new high resolution melting curve analysis was more efficient,more convenient than direct sequencing.Moreover,it was a low-cost test,which was suitable for clinic test.

Objective:To study the clinical efficacy of vitrectomy combined with cataract surgery enin the treatmt of proliferative diabetic retinopathy.Methods:90 patients of proliferative diabetic retinopathy who were treated from January 2013 to June 2016 in our hospital were selected.According to random number table,those patients were divided into the observation group (n=45) and the control group (n=45).The control group was treated with vitrectomy+lentectomy,while the observation group was treated with vitrectomy+ phacoemulsification.Then the best corrected visual acuity,tear interleukin (IL)-2,fluorescein (FL),breakup time of tear film (BUT) and Schirmer test(SIt) and incidence of complications were compared.Results:After operation,the best corrected visual acuity of observation group was better than that of the control group(P＜0.05);the tear IL-2 level in the observation group was significantly higher than that of the control group (P＜0.05);the FL in the observation group was significantly lower than that of the control group,the BUT and SIt were significantly higher than those of the control group (P ＜ 0.05);the incidence rate of capsular opacity,iris neovascularization,corneal edema,xerophthalmia in the observation group was significantly lower than that of the control group (P ＜0.05).Conclusion:Vitrectomy combined with phacoemulsification was effective for proliferative diabetic retinopathy,which could promote the recovery of visual acuity after surgery,improvement of tear secretio and decrease the complications.
