OBJECTIVETo investigate the association between cervical curvature and cervical sympathetic symptoms.

METHODSThe clinical data of 318 patients with cervical spondylosis who underwent surgical treatment in our department between July 2003 and December 2007 were retrospectively analyzed. All patients were divided into group without sympathetic symptoms (n = 284) and group with sympathetic symptoms (n = 34) . The curvatures of both groups on cervical lateral radiographs were measured using Borden method and statistical analysis was performed.

RESULTSThe incidence of abnormal cervical curvature in group with cervical sympathetic symptoms were 67.6% (23/34), which was significantly higher than that in group without cervical sympathetic symptoms (50.7%, 144/284) (P < 0.05).

CONCLUSIONCervical curvature abnormality may be an independent factor that affects the cervical sympathetic symptoms.

Physiological monitoring devices in modern clinical area are basically used electrodes or sensors directly touching the surface of human subject body, which will increase physiological and psychological load of the subjects. In order to realize non-contact monitoring of respiration and heartbeat, firstly, the micro bioradar was used to detect human body motion signal. Then, the respiration signal and heartbeat signal was extracted from the body-motion signal by using signal and conditioning circuits, digital filter and signal processing. Finally, the results of heart rate and breathing rate was wirelessly transmitted. The experimental results showed that the device for non-contact monitoring of respiration and heartbeat waveforms has advantages of small volume, low power consumption, which can realize the monitoring of physiological parameters in real time.

Objective To investigate the influence of age on recent prognosis of elderly inpatients with acute myocardial infarction (AMI).Methods A total of 2535 inpatients with AMI were divided into different age groups.The influences of age and coexistent diseases on prognosis in AMI patients were analyzed retrospectively.Results The hospital mortality and 30-day mortality were higher in patients aged ≥80 years compared with patients aged 65-79 years and patients aged 60-64 years(χ2 =46.378,P<0.01 ;χ2 = 44.534, P<0.01).In 60-64 years old patients with AMI, the prevalences of old myocardial infarction (OMI), renal insufficiency, respiratory insufficiency were higher and the prevalence of angina pectoris was lower in death group than in survival group (all P<0.05).In 65-79 years old patients with AMI, the prevalences of OMI, hypertension, diabetes,cerebrovascular disease, renal insufficiency, respiratory insufficiency were higher and the prevalence of angina pectoris was lower in death group than in survival group(P<0.05).In 80-94 years old patients with AMI, the prevalences of OMI, diabetes, cerebrovascular disease, renal insufficiency, respiratory insufficiency were higher and the prevalence of angina pectoris was lower in death group than in survival group(P<0.05).The prevalences of OMI, hypertension, diabetes, cerebrovascular disease,respiratory insufficiency were significantly increased in 80-94 years old death group versus 60-64 and 65-79 years old death group(all P<0.05).Conclusions The mortality rate of elderly patients with AMI is increased with age and atypical angina pectoris should be paid more attention in these patients.

Objective To study the effects of a synthetic miR3619-5p mimics on bladder carcinoma cell lines of EJ and T24 in vitro.Methods EJ and T24 cells were cultured in vitro and treated with three different processing:negative control group(tinfection with dsControl),positive control group(infection with dsP21-322) and the experimental group(infection with miR-3619-5p)during October 2015 to March 2016.Real-time fluorescent quantitative PCR (qPCR) was performed to detect the expression of p21 mRNA,cell cycle protein D1 (CyclinD1) and cell cycle-dependent kinase (CDK4 and CDK6) mRNA.Western Blot method was conducted to evaluate the expression of p21,CyclinD1 and CDK4 and CDK6 proteins;the change of cell cycle was displayed by flow cytometric analysis.Colony formation assay was used to test the ability of single cancer cell clone proliferation.Cell proliferation assay(MTS) was implemented to observed the inhibitive effect of cell proliferative potential.Results qPCR results showed that miR-3619-5p upregulated p21 mRNA expression (P ＜ 0.05),while the expression of CyclinD1,CDK4 and CDK6 were a little lower(P ＜ 0.05) in EJ and T24cells,respectively.Western Blot analysis testified that the expressions of p21,CyclinD1,CDK4 and CDK6 were difference among groups.Flow cytometry displayed that,the G0/ G1 phase increased significantly after transfected with miR-3619-5p and dsP21-322,compared with dsControl group(P ＜ 0.05),indicating that the cell cycle block in G0/G1 phase.Cell colony formation assay certified that the colony formation rates were less in the groups of miR-3619-5p and dsP21-322 than in that of dsControl group(P ＜ 0.05).Cell proliferation assay demonstrated that,cell proliferation ability decreased obviously when transfected with miR-3619-5p and dsP21-322 (P ＜0.05),compared with dsControl group.Conclusions miR-3619-5p could up-regulate the expression of p21 by RNA activation pathway and remarkably induced cell cycle arrest in G0/G1 phase,inhibiting the proliferation of bladder cancer cells.

Group A,the differences among the three groups were statistically significant(P0.05). TCR,CCR,DAP,OD,BRC in Groups B and C showed trends of increasing,the differences in terms of the contents of BMP-RⅠamong the 3 phases were statistically significant(P0.05);the ER in Group B and C showed a trend of decreasing,thee difference between 4- and 8-week and 4- and 12-week were signifieantly dif- ferent(P0.05).Conclusion After application of glucocorticoid for a short term,pathological changes maintained and showed trends of inereasing in early stage.HBO can reverse these changes.The outcome of 3-course HBO therapy is better than that of 1-course therapy.

Objective To investigate the proliferation and identification of dendritic cells(DC)de- rived from peripheral blood of patients with bladder cancer in vitro.Methods The mononuclear cells were prepared from peripheral blood of patients with bladder cancer by Ficoll-Hypaque centrifugation method,and were induced by the recombinant cytokines hGM-CSF(50 ng/ml),hlL-4(10 ng/ml)and hTNF-?(50 ng/ ml)for 2 weeks.The growth and morphology of DC were observed through the phase contrast or electron mi- croscope,and their pheuotypes were determined by flow cytometry.The capacity of DC to activate T cell-de- pendent anti-tumor immune responses was tested by MTT method.Results The DC cultured in vitro turned into suspensive growth from adhesive situation on the 6th day,then the number of DC increased con- tinuously and the cells showed the irregular morphologic appearance of DC with veiled edges on the 8th day. Flow cytometry showed that the mature DC expressed high levels of specific markers such as CD_(1a),CD_(83), CD_(86)and HLA-DR.T cells activated by DC showed strong cytotoxicity to bladder cancer cell line BIU87 with a killing rate of(48.8?3.7)%,while the killing rate of T cells which were not activated by DC was(25.7?1.5)%;the difference of the rate between them was significant(P＜0.01). Conclusions The DC can be cultured from peripheral blood of patients with bladder cancer by induction of rhGM-CSF,rhIL-4 and hT- NF-?in vitro.This may lay an experimental foundation for further research on DC vaccine.
