Objective To observe the effect of tai chi chuan on anneal dyspnea and endurance stamina of patients with chronic obstructive pulmonary disease (COPD).Methods 80 COPD patients were randomly divided into control group (n=40) and training group (n=40). The common therapy of two groups was the same; but the training group was added with Chen style tai chi chuan training for 30 minutes one day. At the same time, all patients were evaluated about the dyspnesa exponent before and after 3 months training.Results There were no significant differences in FEV1(%), FEV1/FVC(%),heart rate and breath frequency/minute before and after treatment (P>0.05) between two groups, but in dyspnea exponent, there was a significant difference between two groups (P<0.05).Conclusion Tai chi chuan training can reduce the symptom of COPD patients.

The liquid-chromatography-mass technology was used in the metabolomic analysis of mouse's blood 1 hour after exhaustive exercise,in order to explore the potential mechanism of Rhodiola in fatigue elimination of exhaustive exercise mouse.The exhaustive mouse model was made by loaded-swimming.A total of 24 mice were randomly divided into theRhodiola + exercise group,exercise group andno-exercise group.The dose of Rhodiola was 0.4375 g·kg-1·d-1.The loaded-swimming was conducted after two successive weeks of medication.Blood was collected 1 h after swimming for the sample preparation.The enzyme assay and anthrone colorimetry were used to test blood lactate acid and glucose,respectively.UFLC-Q-TOF was used to detect metabolic profiles of each group.The principal component analysis (PCA),orthogonal partial least squares discriminant analysis (OPLS-DA) and heat map analysis were used to compare differences among groups with score chart and to obtain the characteristics biomarkers by load chart.The results showed that the blood lactate acid level of theRhodiola+ exercise group was significantly lower than that of theexercise group.And the glucose level of theRhodiola+ exercise group was significantly higher than that of theexercise group.The metabolomic analysis showed that there were no obvious changes on 1,25-(OH)2D3,diacylglycerol (DG) and inositol triphosphate (IP3).All three materials in theRhodiola + exercise group were significantly lower than those of theexercise group.They were much closer to theno-exercise group.And all three materials were related to the increasing of muscle tension.It was concluded that Rhodiola had the function of promoting fatigue eliminating.This effect may be related to cell membrane protection,regulation of 1,25-(OH)2-D3→IP3,DG pathway,and relieving of muscle tension after exercises.

Background Phlyctenular ophthalmia is a delayed hypersensitivity reaction to some microprotein and affected mainly by adolescent in high incidence.Objective This study was to investigate the microscopy findings of phlyctenular ophthalmia and evaluate the histological changes by laser scanning confocal microscope.Methods Twenty-nine eyes suffered from phlyctenular ophthalmia and twenty normal eyes were examined using laser scanning confocal microscope.The pictures were taken by a CCD camera.All the cases had initially chest X-ray,tuberculin test,bacterial and mycobacteria culture.Results Dendritic and inflammatory cells were increased and concentrated in conjunctiva,and epithelial cells were deformed and squamatizated.The capillaries engorged and the goblet cells were injured.The corneoscleral Vogt meshing of the phlyctenular keratitis was obscured and dendritic cells were intruded into the corneas.The corneal epithelium of phlyctenular keratitis was absent and the subepithelial nerve plexus were bended and fractured,and the dendritic and inflammatory cells were intruded.Scarring of corneal stroma was seen under the laser scanning confocal microscope.Conclusions Laser scanning confocal microscopy is valuable for basic research and clinical diagnosis of phlyctenular ophthalmia.

Objective To investigate the adjustment of miRNA-155 on CD4+ CD25+ Treg regulative T cell in peripheral blood in patients with acute cerebral infarction (ACI) and its pathogenesis. Methods Sixty patients with ACI were divided into three groups according to clinical neurological deficit score. Twenty healthy volunteers were enrolled into the control group. The expression levels of plasma miR-155 mRNA and Foxp3 mRNA were detected by real-time quantitative PCR(qRT-PCR). IL-10 levels in plasma were detected by ELISA. Results Expression of miR-155, Treg, Foxp3 mRNA and levels of IL-10 were significantly increased in patients with ACI compared with normal control group, with statistical differences; Expression of miR-155, Treg, Foxp3 mRNA and levels of IL-10 were gradually increased. The values showed significant statistical difference among the mild, moderate and severe ACI groups (P < 0.01). Among the patients,the levels of miR-155, Treg, Foxp3 mRNA and levels of IL-10 in the survival group were obviously lower than those in the non (P<0.05 or P<0.01). There was a positive correlation between miR-155 and Treg, Foxp3 mRNA (P < 0.01). Conclusion This study suggests that miR-155 is involved in the cell proliferation regulation of CD4+ CD25+ Treg cells,and plays some role in the immunological dissonance with ACI.

Objective To investigate the clinical and pathological characteristics of normotensive pheochromocytomas ( NP) . Methods This retrospective study included 97 patients with a pathological diagnosis of pheochromocytoma at the Drum Tower Hospital Affiliated to Nanjing University Medical School during January 2004 to December 2013. All available clinical, biochemical, and radiological records were reviewed in these patients who were then categorized into hypertensive pheochromocytomas (HP) (n=64) and NP (n=33) groups. 97 cases of Adrenal Gland Scale Score of pheochromocytoma were examined, including tissue microscopic pathology assessment, ki67 and phenylethanolamine-N-methyltransferase ( PNMT ) immunohistochemistry and catecholamine type. Biochemical examinations of 95 subjects with primary hypertension ( PH) were recorded for comparative study. Results The patients with NP showed lower proportion of clinical triad than HP, inapparent metabolic disorders, and lower urinary catecholamine levels than HP, but showed higher results than primary hypertension. The weight of tumor was positively correlated with 24 hour urinary norepinephrine level in patients with HP(Y=1. 376+0. 653X,R2=0. 118, P=0. 028), but not in patients with NP;and the size or diameter of the tumor was negatively correlated with PNMT immunohistochemistry in patients with NP(Y=0. 940-0. 356X, R2=0. 494, P=0. 005), but not in patients with HP, indicating that NP may be misdiagnosed clinically. Conclusion Patients with NP have distinct clinical, biochemical, and pathological phenotypes; the phenotypic changes are closely related with the expression levels of catecholamine pathway products during the occurrence and development of the tumors.

Objective To explore the recuperative effect of immunological function and nutritional status on the patients treated by immune enteral nutrition in early stage after severe multiple injury (SMI). Method The patients with SMI,in department of Trauma Surgery,Tongji Hospital,Tongji Medical College, Huazhong University of Science and Technology,between January 2006 to May 2007 were randomly divided into 2 groups: immune enteral nutrition group (IEN group, 20 cases), enteral nutrition group (EN group, 20 cases). The health persons served as the control group(15 cases) .Since 1st postinjury day, all patients were treated with nutritional support. The T-cell subgroup in periphera blood were detected by FCM and the level of PA, RBP, IL-2 and IL-4 in blood serum were detected by ELASA on the 1st, 3rd,5th, 8th postinjury day. Results After the treatment of IEN and EN,the serum levels of PA, RBP and the proportion of T-cell subgroup were significantly increased on the 8th postinjury day compared with on 1st postinjury day (P ＜ 0.01), but there were no differences between IEN group and EN group. The level of IL-4 were significantly decreased and the level of IL-2 were significantly increased in each group on 8th postinjury day, at same time, the level of IL-2 were significantly increased in IEN group compared with EN group (P ＜ 0.05), and the level of IL-4 were significantly decreased in IEN group compared with EN group (P ＜ 0.05). The duration of SIRS was transient and the infected complication was low on the patients treatment by IEN than EN. Conclusions On the patients with severe multiple injury, IEN was most ascendant than EN to improve the immunosuppression and clinical prognosis.

Objective To explore the effects of PDCA-based self-management intervention model on health behavior and medication adherence in aged patients with percutaneous coronary intervention (PCI). Methods Totally 130 aged patients treated by PCI were randomly divided into the intervention group and the control group with 65 patients. The patients in the control group received routine health education, and the patients in the intervention group received PDCA-based self-management intervention model. All patients were investigated with Coronary Heart Disease Self-Management Behavior Scale (CSMS) and Health Promoting Lifestyle Profile (HPLP) and Medication Compliance Scale (MMAS-8) 3 months and 6 months after discharge. Results Six months after discharge, the score of self-management and healthy behavior and medication adherence were 96.98 ± 14.12, 131.86 ± 16.53, 7.18 ± 0.69 respectively in the intervention group, and the score of them were 86.04 ± 11.78, 105.33 ± 10.97, 5.69 ± 1.29 respectively in the control group, and the difference was statistically significant (t=10.981, 10.793, 7.438, P<0.05 or 0.01). Conclusions PDCA-based self-management intervention model is a patient-centered, problem-oriented, dynamic and interactive health education intervention. It may be helpful in improving PCI patients′ health behavior and medication adherence after discharge. And it may establish lasting self-management skills, and is worthy of application and promotion.
