Objective To investigate the expressions and significance of cyclinD1 in oral squamous cell carcinoma (OSCC). Methods The published studies were searched in the Cochrane Library,Embase,PubMed,CNKI,VIP,Wanfang and CBM databas-es,the quality of the included studies was assessed.Revman5.0.1 software was adopted to test for heterogeneity of the selected re-search literature and analyze the correlation of cyclinD1 and OSCC by calculating OR and 95%CI .Results A total of 31 case-con-trol studies were included in the study,the case group (OSCC group)was 1 604 cases and the control group was 864 cases (inclu-ding normal oral mucosa tissue 452 cases and precancerous lesions 412 cases).The Meta analysis of results showed that the expres-sion of CyclinD1 in oral squamous cell carcinoma was significantly higher than normal tissue[OR (95%CI )at 11.92 (6.71 -21.18)].CyclinD1 was related to differentiated degree,lymph node metastasis and clinical stage of OSCC positively(P <0.05),but was not related to age and gender (P >0.05).Conclusion According to the current relevant research,the over expression of cy-clinD1 is closely related to occurrence and development of OSCC,which might be valuable for the early diagnosis,treatment,and prognosis of OSCC.

Objective:To observe whether transforming growth factor-beta 1 (TGF-?1) can improve the mechanical properties of tissue engineered heart valve (TEHV) prepared by TGF-?1 and myofibroblasts.Methods:Myofibroblasts were isolated,cultured,identified,and seeded onto the decellularized aortic valve leaflet.In the experimental group,TEHV were cultured with DMEM containing 10 ng/ml TGF-?1 for 14 days.In the control group,TEHV were cultured with DMEM only for 14 days.The contents of lysyl oxidase (LOX) and hydroxyproline,the expression of LOX and COLL-1 mRNA,and the mechanical properties of the TEHVs were analyzed in each group.Results:The contents of LOX and hydroxyproline,expression of LOX and COLL-1 mRNA,Max-load,and Max-stress were significantly higher in the experimental group than those in the control group (all P

ObjectiveTo analysis the clinical characteristics and the high risk factors of children with cerebral palsy.MethodsClinical data of 100 children with cerebral palsy were retrospectively analyzed.Results51% of children were born with asphyxia, 42% were born prematurely, 39% were low birth body weight. 85.7% of children involved had mental retardation, 12% had hearing loss and 7% had visual impairment. 88% of children involved had abnormal cranial CT results and 46.1% had abnormal EEG. 50.0% of the children had abnormal brain stem auditory evoked potentials.ConclusionAsphyxia, prematurely birth and low birth body weight are high risk factors of cerebral palsy. Most of the children with cerebral palsy in this group are mental retarded.

Objective:To investigate the effects of survivin antisense oligonucleotide (ASODN) on expression of survivin and ACC-M cell apoptosis. Methods: A phosphorothioate antisense oligonucleotide (ASODN) of specific target survivin was designed and synthesized and then transferred to ACC-M cell line by lipofectin. At the same time blank control group, sense oligonucleotide (SODN) group were set up for comparison. MTT assay was used to detect cytotoxicity. Apoptosis was observed by flow cytometry. Survivin expression was determined by RT-PCR and Western-Blotting. Results: Compared with control group and SOND group, in ASODN groups, the expression of survivin mRNA and protein were obviously weak, apoptosis rate apparently increased, cells growth was inhibited. There was no obviously difference in SODN and control groups.Conclusion:ASODN can down-regulate the expression of survivin gene in ACC-M cell line specifically. It plays an important role in inducing tumor apoptosis and suppressing cell proliferation.

Objective:To study the changes of upper airway dimension and morphology in Class Ⅱ mandibular retrusion children af-ter functional treatment by Twin-block appliance.Methods:The Cone-Beam CT(CBCT)data of upper airway of the subjects were measured with Dolphin 11.5 software before and after fuctional treatment by Twin-block appliance.The comparison of upper airway di-mension and morphology between pre-treatment and post-treatment was performed by paired t-text.Results:After functional treatment the volume of total upper airway,velopharyngeal airway,glossopharyngeal airway,laryngopharyngeal airway,oropharyngeal airway,the sectional area of the inferior of the soft palate(SP),tip of the epiglotti(TE),the sagittal diameter of SP,the lateral diameter of SP and TE increased(P <0.05)in the children;the airway's shape of SP was attended to be rounder and TE to be more flat.Conclusion:Functional treatment is effective in the treatment of skeletal Class Ⅱ mandibular retrusion of children by increase of the upper airway and improvement of respiration.

Objective · To investigate the prevalence of passive smoking among pregnant women in Shanghai and to analyze its influencing factors and to provide the basis and suggestion for making related intervention measures to reduce the harm of secondhand smoke on the health of pregnant women. Methods · From July to October 2014, pregnant women and their spouses were recruited for a questionnaire investigation at the antenatal care clinics of 3 maternity hospitals and 3 community hospitals in Shanghai. The questionnaire included demographic information, family basic situation and cognitive status of passive smoking. Results · The passive smoking rate before pregnancy in the 2831 pregnant women, who were involved in the investigation, was 17.1%. The passive rate during pregnancy was 7.8%. The difference between these two rates was statistically significant (P<0.05). 71.0% of the pregnant women have passive smoking for 15~59 min each day. Relative to home and work place, the passive smoking rate of pregnant women in public place was the highest (P<0.05). The passive smoking rate of pregnant women was significantly associated with the educational level of smoking spouses and the attitude of pregnant women when they faced the smokers. Conclusion · The passive smoking rate of pregnant women is influenced by the educational level of their spouses and the pregnant women's feedback to the smokers face to face. Public places are the most important exposure places to secondhand smoke for pregnant women. In order to reduce the harm from passive smoking to pregnant women and their fetuses, the related measures of smoking control at home education and smoking ban in public place should be made.

As one of the major geriatric syndromes,frailty exerts adverse effects on life expectancy and quality of life of the elderly.Because of its importance,a number of methods and tools have been introduced for the assessment of frailty.Malnutrition,as an independent risk factor,interacts with frailty and is involved in its progression.This article reviews recent studies on frailty and malnutrition.

Objective To retrospectively analyze the treatments of nonvalvular atrial fibrillation (nvAF) in elderly patients aged 80 years and over,and to investigate the influencing factors for occurrence of stroke and transient ischemic attack(TIA)and relationships between antithrombotic therapy and stroke or TIA.Methods 101 elderly patients with nvAF were enrolled and grouped according to the occurrence of stroke/TIA and antithrombotic-correlated bleeding.The influencing factors were retrospectively analyzed and antithrombotic schemes were compared.Results Incidence rate of stroke/TIA was 28.7％ (29/101).Among all patients,70 cases were treated with antiplatelet therapy,19 cases were treated with anticoagulation therapy,while 12 cases received no antithrombotic (antiplatelet or anticoagulation) therapy before stroke.Both the nvAF time course and the antithrombotic strategy were significantly different between post-AF stroke/TIA group and non-postAF stroke/TIA group(both P＜0.05).The difference was reflected in ratios of antiplatelet therapy/anticoagulation therapy.The proportion of anticoagulation therapy was higher in non stroke/TIA group(x2 =5.778,P =0.016).Different antiplatelet therapy scheme significantly affected occurrence of stroke/TIA(P＜0.05).There was no significant effect of antithrombotic schemes on hemorrhagic events(x2=0.708,P =0.702).Multiple logistic regression analysis showed that hypertension,coronary heart disease,cancer,diabetes and previous stroke history,as well as nvAF duration were the independent risk factors for post-AF stroke/TIA(OR=1.351,95 ％CI:1.129-1.617).Conclusions Currently,the proportion using anticoagulation therapy is low,and single antiplatelet therapy is the main regimen in the elderly patients with nvAF.For elderly patients with nvAF,anticoagulation therapy has a protective effect against the occurrence of post-nvAF stroke/TIA,meanwhile there is no significantly increased risk of bleeding,which makes anticoagulation therapy advisable in the elderly.The nvAF time course is one of the risk factors,which is worth experts' attention in risk evaluation of thrombus in elderly patients.
