Objective To investigate the relationship of plasma brain natriuretic peptide (BNP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels with the severity of heart dysfunction in elderly patients with heart failure. Methods BNP levels were measured by immunofluorescence in 106 hospitalized patients with heart failure, while NT-proBNP levels were measured by electrochemiluminescence immunoassay in 48 patients. The severity of heart dysfunction was determined by NYHA classification. The left ventricular ejection fraction (LVEF) measured by Color Doppler Ultrasound was used to show the left ventricular systolic function. Results In patients with BNP≤400 ng/L versus BNP>400 ng/L, the rates of LVEF≤45% were 16.4% versus 46.8% (χ~2= 13. 93, P=0. 001), the rates of E/A<1 were 62.3% versus 40. 4% (χ~2 =22. 19,P = 0.024) and the rates of Cr>107 μmol/L were 13.1% versus 38.3% (χ~2 = 11. 31, P = 0. 002) . In patients with NT-proBNP≤400 ng/L versus NT-proBNP>400 ng/L, the rates of LVEF≤45% were 25. 0% versus 58. 3% (χ~2 = 10. 00,P = 0. 019) and the rates of Cr>107 μmol/L were 20. 8% versus 50.0% (χ~2=8. 50,P = 0. 035). Conclusions BNP or NT-proBNP levels increase significantly along the deterioration of the heart failure severity, and it may be important to use BNP or NT-proBNP to predict left ventricular function.

Objective To evaluate the effectiveness of A type behavior in the development of essential hypertension.Methods The questionnaire of A type behavior were used to investigate 230 patients,divided into hypertension group (147) and no hypertension group (66). There are 89 patients and 14 patients of A type behavior in each group. 17 patients were eliminated. In some patients including A type (24 cases) and B type (26 cases), the level of norepinephrine (NE), renin (Ren) , angiotensin Ⅱ (AngⅡ), aldosterone (Ald) was tested. Results There were more A type behavior in hypertension group than no hypertension group, P 0.05).Conclusions The result confirmed that A type behavior has some influence on the development of essential hypetension and has some adverse effect on prognosis of patients.

Objective To investigate the clinical efficacy and safety of six-hole moxibustion box therapy for stable chronic obstructive pulmonary diseases(COPD).Methods Sixty patients with thoracic facet joint disorder were randomly allocated to treatment and control groups, 30 cases each. The control group inhaled tiotropium bromide inhalation powder spray and the treatment group received six-hole moxibustion box therapy in addition. The COPD Assessment Test (CAT) score and the dyspnea score were recorded and peripheral blood oxygen saturation was measured in the two groups before and after treatment. The adverse reactions were monitored in the two groups. Results There were statistically significant pre-/post-treatment differences in the CAT score and the dyspnea score in the two groups (P<0.05). There were statistically significant post-treatment differences in the CAT score and the dyspnea score between the treatment and control groups (P<0.05). There were statistically significant differences in pre-/post- treatment CAT score difference value and dyspnea score difference value between the two groups (P<0.05). There was a statistically significant pre-/post-treatment difference in peripheral blood oxygen saturation in the treatment group (P<0.05). There was a statistically significant post-treatment difference in peripheral blood oxygen saturation between the two groups (P<0.05).Conclusion Six-hole moxibustion box therapy plus tiotropium bromide inhalation powder spray is safe and effective in treating stable COPD.

Objective To explore the association between clinical pathological characteristics and the expressions of epidermal growth factor receptor (EGFR) and protein kinase B (AKT) in gastric carcinomas.Methods The expressions of EGFR and AKT were measured with immunohistochemical method in the cancer tissues and cancer-adjacent normal tissues from 153 cases of patients with gastric cancer.The association between clinical pathological characteristics and their expressions were analyzed.Results The expressions of AKT and EGFR in gastric cancer tissues had no relationship with gender,age,pathological type,and the degree of differentiation (P ＞ 0.05).A positive correlation was existed between the EGFR and TNM stages (x2 =5.43,P ＜0.05).The AKT was positively related to the size,T stage,and TNM stage of the tumor,respectively (x2 =4.73,4.95,5.32,P ＜0.05 orP ＜0.01).The levels of AKT (x2=4.83,4.75,P ＜0.05) and EGFR(x2 =4.67,4.58,P ＜0.05) in the gastric cancer tissues with lymph node and/or distant metastasis were significantly higher than the gastric cancer tissues without metastasis,respectively.Conclusions The over-expressions of AKT and EGFR would benefit the diagnosis and stages of a gastric cancer and the determination of its metastasis.

ObjecfiveTo investigate clinical features and imaging manifestation in patients with posterior reversible eneephalopathy syndrome (PRES) to improve its recognition.MethodsSix patients with PRES were enrolled,four women with history of end-stage renal disease,kidney transplantation,eclampsia,or systemic lupus erythematosus (SLE) and two men with history of chemotherapy or hypertension.All of them underwent multi-serial MR imaging (T1 WI,T2 WI,FLAIR) and post-contrast T1 WI.Three cases also underwent CT scan and gadolinium enhancement. ResultsAll the six cases of PRES had different inducing causes such as acute hypertension,preeclampsia or eclampsia, taking immunosuppressive agents or steroids.and their clinical symptoms were characterized by sudden occurrence of headache,eclampsia or seizure of epilepsy,altered melltal status,visual disturbances.Clinical symptoms were died out in about one week after prompt and appropriate treatments for high blood pressure.or removal of precipitating factors,or treatment for epileptic seizures or status epilepticus.MRI and CT scanning demonstrated multifocal subcortical white lesions in bilateral parieto-occipital lobes (six cases), bilateralfrontal lobes (two cases),bilateral post temporal lobes (two cases) and left cerebellum (one cases).and cortical involvement (two cases).All lesions appeared unenhanced with gadolinium enhancement. FoHow-up by MRI showed decreased abnormal signs and small infarct foci were left in the cortex-subeortex of one case.ConclusionsPRES is a clinico-neuroradiologieal transient condition, usually benign and reversible in nature.Completely clinical and radiographic recovery Can be achieved with prompt antihypertensive treatment or removal of precipitating factors and supportive care,but delayed diagnosis and therapy Can result in cerebral infarct with neurological sequelae.

Objective To assess and compare chemical and immunochemical fecal occult blood tests (FOBTs) in diagnosis of gastrointestinal hemorrhage and their clinical significance. Methods The FOBT was carried out in 4474 in-patients, out-patients or subjects who had annual physical examination using both hemoccult Ⅱ (CFOBT) and colloidal gold chromagraphy (IFOBT) methods.Those who was positive for FOBTs would be re-tested for 2 times and followed by gastroscopy and colonoscopy as well as other examinations in order to find the reason and location of gastrointestinal hemorrhage. Results FOBT was positive in 390 (8.22%) patients, of which 163 (41.8%) were detected by CFOBT, 100(25.6%) by IFOBT, and 127(32.6%) by both CFOBT and IFOBT. The clinical, endoscopic and other examinations revealed that upper and lower gastrointestinal bleeding were found in 235 (60.3%) and 136 (34.9%) patients, respectively. The detective rates of upper and lower gastrointestinal bleeding were 90.2% and 67.6% by CFOBT respectively, and 42.5% and 93.4% by IFOBT, respectively. The obvious gastrointestinal bleeding could be detected by both CFOBT and IFOBT. The diseases related to gastrointestinal bleeding involved acute gastric mucosal lesion, peptic ulcer, gastric cancer and colonic polyp,colorectal cancer and piles, etc. Conclusions It is demonstrated that FOBT is still important in screening and diagnosis of gastrointestinal hemorrhage.The CFOBT is superior to IFOBT in detecting upper gastrointestinal bleeding, whereas the IFOBT is superior to CFOBT in detecting lower gastrointestinal bleeding.

OBJECTIVE: To investigate the relationship between the expression of leptin, p-mTOR protein and the pathogenesis, development and clinicopathological features in colon carcinoma. METHODS: The expression of leptin and p-mTOR protein was evaluated by immunohistochemical methods in 40 normal colon mucosas, 40 colon adenomatous polyps and 108 cases of colon carcinomas. The relationship between the staining pattern and clinicopathogical features was examined. RESULTS: The positive rates of detection of leptin in normal colon mucosa, adenomatous polyps and colon carcinomas were 10% (4/40), 27.5% (11/40), and 71.3% (77/108), respectively; with significant differences among the three groups (P<0.05). The positive rates of p-mTOR protein in the normal colon mucosa, the adenomatous polyps, and the colon carcinomas were 2.5% (1/40), 20% (8/40), and 61.1% (66/108), respectively; with significant differences among the three groups (P<0.05). The expression of leptin and p-mTOR proteins were related to invasive depth, TNM stages, lymph node metastasis, distant metastasis and tumor differentiation (P<0.05), but not to age, sex, or site (P>0.05). In colon carcinoma tissues, leptin expression was positively correlated with p-mTOR expression (P<0.01). CONCLUSION Leptin and p-mTOR proteins may play important roles in the occurrence and development of colon carcinoma. The detection of leptin and p-mTOR may be helpful for evaluation of the prognosis of the patient with colon carcinoma.
