Objective To observe the changes of malondialdehyde (MDA), superoxide dismutase (SOD-1) in serum and plasma endothelin (ET)and angiotensin II(AⅡ) in patients with severe closed head injury before and after being treated with hyperbaric oxygenation (HBO). Methods Fifty patients were recruited. Thirty-two patients were treated with HBO in addition to the conventional management (HBO group) and the other eighteen patients without HBO except for conventional management served as the controls (control group). Thirty healthy volunteers served as normal controls (normal group). Activities of MDA ,SOD-1,ET and AII were measured with spectrometry and radioimmunoassay in all the subjects, respectively, during the study. Results Before treatment, there was a significant difference between the normal group and HBO group as well as the control group in regard to the activities of the 4 parameters(P0.05) as the 4 parameters were concerned. The patients scored 3-5 with GCS in the control group were significantly different from those scored the same with GCS in the normal group in terms of the SOD-1 and MDA. Higher GCS was found in patients with low activities of MDA, ET and AII but high SOD-1 levels. Favourable changes of GCS and GOS were observed in patients in the HBO group as compared with those in the control group (P

FOXP3,a member of the forkhead/winged-helix family,exerts its immunosupression effect by regulating the development,differentiation and maturation of CD4+ CD25+ regulatory T cells(Treg).Treg plays an important role in immune escape mechanism in oncology research.This article reviews the expression of FOXP3 in various types of tumors and its role in tumor immunology and immunotherapy.

This paper reviewed the policies on private medical institutions in Henan province since the new healthcare reform.Combined with relevant statistical data,the authors found that conceptual obstacles,policy implementation,lack of unified management and restriction of human resource flow as important constraints of the development of such institutions in the province.In view of this finding,the authors made in-depth study of the development positioning,general role of planning and market functions,as well as support and regulation in parallel of such institutions,in order to promote the healthy and sustainable development of private medical institutions in China.

Objective To discuss the uhrasonography and hemodynamic characteristics of carotid atherosclerosis in elderly patients with coronary heart disease (CHD).Methods The 548 people were divided into CHD group (n = 373) and control group (n = 175) by the coronary angiography.And the patients in CHD group were sorted into myocardial infarction (MI) group (n= 160) and non-MI group (n= 213).All patients were above 60 years of age, and underwent carotid artery ultrasound examination.The data of carotid sonography and hemodynamics were classified and analyzed using SPSS 10.0 software.Results The carotid intima-media thickness (IMT), plaque thickness and score were much more in CHD group than in control group [(0.96±0.24) mm vs.(0.78±0.11) mm, (1.90±0.36) mm vs.(1.66±0.13)mm, (2.2±0.7) vs.(1.9±0.4), t= 14.81, 27.89 and 27.83, all P=0.00].A total of 161 (43.2%) patients had atherosclerotie plaques in CHD group, and there were 7 (4.0%) people with plaques in healthy control group(χ~2 =337.18, P =0.00).And there were 81.3% of patients with plaques in MI group, it was more than non-MI group, in which there were 12.9% of patients with plaques (χ~2 =60.88, P=0.00).The carotid peak systolic velocity (PSV) and resistance index (RI) were both higher in CHD group than in control group [(77.0±11.9) cm/s vs.(65.2±3.1) cm/s and 0.77±0.06 vs.0.67±0.08, (t= 12.26 and 50.43, P=0.00)].Conclusions Carotid ultrasonography could evaluate not only CHD, but also CHD severity in the elderly.

Objective To observe temporal expression of matrix metalloproteinases(MMP-13) and tissue inhibitor of metalloproteina-ses-1 (TIMP-1) in lung of newborn rats with hyperoxia induced chronic lung disease (CLD),and to explore the relationship of CLD with MMPs.Methods The neonatal rats within 24 hours after birth were randomly divided into hyperoxia-exposed group(n=40) and control group(n=40).On postnatal 1,3,7,14 and 21 days,lung tissue of rats in 2 groups were collected.Lung histological changes were evaluated by hematoxylin and eosin and Masson stain;Collagen Ⅰ was detected by enzyme linked immunoadsorbent assay;MMP-13 and TIMP-1 were identifide by immunohistochemistry.Results Exposured to hyperoxia enviroment for 21 days,the number of alveolar decreased,terminal air space enlarged,inter-alveolar septa thickened,and deposition of interstitial collagen fibers.On 14 and 21 days,collagen Ⅰ in the lung of hyperoxia-exposed group increased significantly compared with that of control group(P0.05),obviously decreased on 21 day(P

Objective To investigate the diagnostic value of anti-cyclic citrullinated peptides ( CCP ) antibodies combined rheumatoid factors (RF) on elderly patients with rheumatoid arthritis.Methods From January 2012 to December 2014, 29 cases of elder patients in our hospital with rheumatoid arthritis (elder RA group, age >60 year), 47 cases of elderly health control group (elder RA group, age≥60), and 48 cases of elder patients without rheumatoid arthritis (non-elder RA group, age<60 year) were selected.The anti-CCP antibodies and rheumatoid factor (RF) levels of three groups were detected, and the significance of anti-CCP antibody combined RF on the diagnosis of elderly rheumatoid arthritis was analyzed.Results Diagnostic positive rate of anti-CCP antibodies +RF was significantly higher than that of anti-CCP antibodies, and the difference was significant (χ2 =7.632, P =0.006).Diagnostic positive rate of anti-CCP antibodies +RF was higher than that of RF, but the difference was not statistically significant (χ2 =3.107, P=0.078).The diagnostic positive rate of anti-CCP antibodies, RF, and anti-CCP antibodies +RF for diagnosis of elderly rheumatoid arthritis had no statistically difference with that of non-elderly RA group.The sensitivity and negative predictive value of anti-CCP antibodies +RF was higher than that of only anti-CCP antibodies and RF.The area under the ROC curve of detecting anti-CCP +RF was 0.786, which was higher than that of anti-CCP antibodies (0.699) and RF (0.663), indicated that the reliability of anti-CCP antibodies +RF was higher than that of anti-CCP antibodies and RF.Conclusion The anti-CCP antibodies and RF can diagnose elderly rheumatoid arthritis, and anti-CCP antibodies combined RF has more clinical significance.

Objective:To investigate the influencing factors for orthostatic hypotension(OH)in elderly patients with hypertension.Methods:This was a case-control study.A total of 224 patients with hypertension aged over 65 years were included.After resting for more than 5 minutes, subjects had their blood pressures measured in the supine and standing position at 0 min, 1 min, 2 min and 3 min.OH was defined as a fall in systolic BP of more 20 mmHg(1 mmHg=0.133 kPa)and/or diastolic BP below 10 mmHg of baseline within 3 min in the upright position.Subjects were divided into the OH group( n=34)and the non-OH group( n=190). Baseline data, comorbidities and differences in medications were compare between the OH group and the non-OH group, and the influencing factors for OH were analyzed. Results:The proportion of drinkers was higher in the OH group than in the non-OH group(29.4% or 10/34 vs.7.4% or 14/190, χ2=14.649, P<0.01). Both systolic pressure(139.0±22.1 mmHg vs.124.5±16.3 mmHg, t=-3.661, P<0.01)and diastolic pressure(77.6±6.3 mmHg vs.69.2±9.0 mmHg, t=-6.696, P<0.01)in the supine position were higher in the OH group than in the non-OH group.The proportions of patients with diabetes(47.1% or 16/34 vs.25.3% or 48/190, χ2=6.731, P<0.05)and stroke(41.2% or 14/34 vs.24.2% or 46/190, χ2=4.233, P<0.05)were higher in the OH group than in the non-OH group.The proportion of patients receiving α receptor blockers was higher in the OH group than in the non-OH group(23.5% or 8/34 vs.4.2% or 8/190, χ2=16.228, P<0.01). After adjusting for factors such as alcohol consumption, diabetes, stroke and other differences between the OH and non-OH group, logistic regression found patients with alcohol intake( OR=5.274, 95% CI: 1.990~13.982, P<0.01), diabetes( OR=2.744, 95% CI: 1.213~6.208, P<0.05)and using α receptor blockers( OR=8.812, 95% CI: 2.835~27.383, P<0.01)had a higher risk of OH. Conclusions:OH is very common in elderly patients with hypertension.Alcohol consumption, diabetes mellitus and the application of α receptor blockers can increase the risk of OH.
