Objective To investigate the mental health and its correlated factors for senile dementia caregivers in nursing homes in Shenyang. Methods Questionnaire survey was conducted among 174 senile dementia caregivers recruited from the Nursing Home of Shenyang and Shenyang Social Welfare Institute by using Symptom Check-List-90 (SCL-90), Social Support Rating Scale (SSRS) and self-designed general information questionnaire and to analyze the scores of self rating scale of nursing staff, the total score of social support scale, and the factors affecting the mental health status of nursing staff. Results The SCL-90 scores of senile dementia caregivers with education levels from illiteracy, primary school or junior high school, high school or secondary school, college or above were 130.50 ± 10.11, 132.70±12.55, 135.06±9.15, 129.24±8.83, the difference was statistically significant (F=15.05, P<0.01). The SCL-90 scores of senile dementia caregivers with poor, general and good perceived health status were 133.40±10.52, 132.60±11.32, 128.00 ±10.02, the differences were statistically significant (F=9.07, P<0.01). The SCL-90 scores of family monthly income of 1001 to 3000 yuan, 3001 to 5000 yuan and more than 5001 yuan were 132.90 ± 10.39, 132.80 ± 11.52, 131.50 ± 8.20, the difference was statistically significant (F=12.11, P<0.01). The multivariate linear regression analysis showed that the regression coefficient of perceived health status was-0.168 (t=2.880, P<0.01), monthly family income was-0.145 (t=-2.512, P<0.05), SSRS was 0.121 (t=2.112, P<0.05). Conclusions Mental health status of senile dementia caregivers in Shenyang is poor. The health sector should take some measures to improve the degree of social support, nursing staff wages and to ensure their health in order to promote physical and mental health of nursing staff and the nursing level so as to improve the quality of life of the senile dementia elderly.

Objective To study the relationship between the MRI features and pathological types of intracranial meningiomas. Methods MRI findings of intracranial meningiomas in 63 cases proved by operation and pathology were analyzed retrospectively.Results Of 63 cases,62 cases were singular and one case was multiple lesions. The lesions were located in frontal,parietal and occipital regions nearby the convexity of the brain in 30 cases,in sellar region in 10,at sphenoidal crest in 8 , at olfactory sulcus in 5 and at other regions in 10. Isointense or slightly hypointense signal on T 1WI was found in 87.27% cases of meningiomas . On T 2WI, tumors had isointense or slightly hyperintense signal in 69.84%, obviously hyperintense signal in 19.05%,heterogenous texture signal in 7.94% and slightly low intense signal in 3.17%. Pathological type was included meningiomas meningothelial(n=29), meningiomas fibrous(n=11) , meningiomas psammomatous(n=8),angioblastic meningiomas (n=5) and meningiomas angiomatous(n=10). Conclusion It is great value in diagnosis of meningiomas with MRI. Meningiomas angiomatous show effecting of blood-vessel flowed empty with MR imaging.

BACKGROUND:In the perspective of traditional Chinese medicine, few studies have focused on the compound preparations though there are many investigations. The present study was undertaken to investigate the effect of Zhenwu Tang Granule on chronic pressure-overloaded left ventricular hypertrophy in rats. METHODS:The study was performed at the laboratory of Guangzhou Institute of Respiratory Disease. Male SD rats were divided randomly into 3 groups:sham operation group (n=8), operation group (n=15) and traditional Chinese medicine (TCM) group (n=15).The model of myocardial hypertrophy was made by gradually constricting the abdominal aorta. Sixteen weeks later, cardiac ultrasonography was performed in all groups in order to ascertain post-operational left ventricular (LV) hypertrophy. And Zhenwu Tang Granule was added at a dose of 12 g/kg in the mixed feedstuff for 8 weeks in the TCM group. In the 24th week, weight, structure as well as function of the heart in each group were measured by high-frequency ultrasonography, and Masson's staining was performed on the cardiac muscles. Meanwhile, total collagen volume fraction (CVF-T) and non-coronary vessel collagen volume fraction (CVF-NV) were analyzed. RESULTS:There was an increase in the weight of the heart in the operation group, with the left ventricule dominated (P<0.05). The heart was enlarged, with diastolic interventricular septal distance (IVSd) and left ventricular posterior wal distance (LVPWd) dominated (P<0.01).There was a significant decrease in the cardiac function (P<0.05). The weight (P<0.01) and volume of the heart decreased in the TCM group compared with the operation group, with IVSd and systolic left ventricular posterior wal dominated (P<0.01). And the cardiac function was improved (P<0.05). Significant interstitial and col agen hyperplasia was shown in the operation group based on pathological analysis, and various improvements were proved in the TCM group, i.e. there was a significant decrease in CVF-T and CVF-NV (P<0.01) compared with the operation group; but no difference (P>0.05) was found when compared with the pseudo-operation group. CONCLUSION:Zhenwu Tang Granule could reduce the weight and volume of the heart, improve the cardiac function, inhibit hyperplasia of collagen, and reverse myocardial hypertrophy in rats with pressure-overloaded left ventricular hypertrophy.

OBJECTIVE: To investigate the potential risk factors and management of excessive epistaxis after endoscopic endonasal surgery (EES). METHOD: Six hundred and forty-one patients who underwent EES in our hospital from December 2011 to December 2012 were reviewed retrospectively. Factors which potentially affect the incidence of excessive epistaxis after EES were analyzed with univariate and multivariate logistic regression model. RESULT: The incidence rate of excessive epistaxis after EES was 8.4% in our study. Multivariate logistic regression analysis revealed that history of previous EES, along with other four factors, correlated significantly with the occurrence of excessive epistaxis after EES. CONCLUSIONS Previous EES, along with other three factors, may increase the chance of excessive epistaxis after EES, while pre-operative corticosteroid therapy may reduce the risk to some extent.

OBJECTIVETo evaluate the effect of milkvetch injection (MI) on immune function of children with tetralogy of Fallot (TOF) after radical operation.

METHODSForty-children with TOF were divided into two groups, the 20 in the control group treated with conventional treatment alone and the 20 in the treated group treated with conventional treatment plus 15 ml of MI every 12 hrs for 14 days. Changes of immunoglobulin, complements, lymphocyte phenotypes and cytokines were observed.

RESULTSIn the treated group, the abnormally increased levels of IgG, IgM, C3, C4, CD8+ and CD19+ began to lower at lst-2nd week after treatment, and basically restored to the levels of normal at 3rd-4th week; while the decreased levels of IgA, CD3+, CD4+, CD4+/CD8+ ratio, CD3+/HLA-DR+ and CD3+/CD16+ -CD56+ raised gradually from the 1st week and restored to normal range at 2nd-3rd week. The IL-6 and tumor necrosis factor-alpha (TNF-alpha) levels in the plasma and supernatant, produced in vitro by peripheral blood mononuclear cells (PBMC) decreased gradually at 1st week and restored to the normal level at 3rd-4th weeks. The different value before and after treatment of the above-mentioned indexes in the treated group were superior to those in the control group (P<0.05 or P<0.01).

CONCLUSIONMI could significantly improve the immune function of children with TOF after radical operation.
