Objective To explore the prognostic value of 24 h ambulatory blood pressure monitoring (ABPM)for target organ damage (TOD) in the elderly hypertension patients. Methods Two hundred and thirty two elderly hypertension patients who were involved at least one target- organ damage experienced 24 h ABPM. All subjects were randomly divided into 3 groups according to the number of TOD and the clinical situation of cardiovascular, cerebrovascular and renal complications. 24 h ABPM recordings of each group were compared with one another. Results The number of TOD were highly correlated with 24 h average systolic pressure, nighttime average diastolic pressure, abnormal circadian rhythm and pressure burden. The difference was significant between patients involved 3 TOD and those with 1 TOD(P

Objective To analyse the mitral annular abnormal motion in patients with myocardial infarction by using M-mode and freguency spectrum Doppler tissue imaging (DTI-M), and study its clinical value in assessing the LV function. Methods The total systolic annular displacement (MD), early diastolic displacement (MDe), late diastolic displacement (MDa) of posterier valve of mitral annular, systolic and diastolic motion velocilies (V S,V E,V A), time velocity integrals (TV IS,TV IE,TV IA) of the lateral wall of the mitral annulus were determined with DTI-M mode and freguency spectrum from apical four-chamber view in 28 cases of patients with myocardial infarction. Results The MD, MDe, MDe/MDa in patients with myocardial infarction were found to be decreased significantly (P

Objective To evaluate the effect of nebulized budesonide and oral prednisolone in treatment of idiopathic pulmonary fibrosis(IPF).Methods Forty-two patients with IPF were randomized to divide into two groups,nebulised budesonide groups and oral prednisolone groups.Symptoms,signs,pulmonary function,arterial blood gases analysis and the adverse effects were measured.ResultsThere were significant improvement of VC and PaO2 of nebulized budesonide and oral prednisolone groups,but there were no significant differences between of nebulized budesonide groups and oral prednisolone groups.The adverse effects in nebulised budesonide group were obviously less than those in oral prednisolone groups.Conclusion Nebulized budesonide was an effective method in treatment of idiopathic pulmonary fibrosis.

As social views on disability changed,how to support intellectual disabled adult so they can be involved in ordinary social life is not only the hot topic of special education and rehabilitation service system,but also the concern of psychologists.For the improvement of social inclusion,psychologists should provide assessment,intervention and support for intellectual disabled adults at personal and social supportive levels,and relative policy advices for the government should be included.

A large number of starring biomedical industry clusters are emerged in recent years with the develop-ment of biomedical industry. The information access approaches of users in biomedical industry clusters consisting of higher education institutions, scientific research institutions and enterprises, the types of biomedical information they need, the transformation ways of their achievements, and the major barriers of information access were thus in-vestigated in this paper with questionnaires. The different information behaviors were compared between the users of scientific research group and enterprise group. The characteristics of information need of users in biomedical indus-try clusters were summarized, and following suggestions were put forward, namely establishing information service platform, perfecting institution-oriented information service model, and improving information service system for bi-omedical industry clusters.

Aplastic anemia (AA) is a Tlymphocyte-mediated autoimmune disease. The research on AA was focused on three areas, which were the pathogenesis of immune dysfunction, hematopoietic stem cell damage and abnormal hematopoietic microenvironment. In recent years, more attentions have been paid on abnormal immune mechanisms in the blood. There are complex intracellular cytokine and signal transduction pathway of pathogenesis in AA. And T-bet/IFN-γ signaling pathway plays an important role in development and progression of AA. This article aimed to review T-bet/IFN-γ signaling pathways in AA.

Extraction of teeth is the most basic and widely used operation of oral and maxillofacial surgery. According to characteristics of extraction of teeth, the author views medical ethics principles which in the diagnoses and treatments process from the aspect of medical ethics, they are,①Doctors must intensify their own quality and self - cultivations and establish the idea of " People First ". ②Doctors must carry on the overall and systematic inspection, make the plan of diagnoses and treatments synthetically toimplement the idea of " People First ". ③Doctors should pay attention to interact with patient, meet different patients' demands and create the harmonious medical environment.

Objective To evaluate the role of ATP-sensitive potassium (KATP) channel in spinal dorsal horn neurons in hyperalgesia after thoracotomy in rats.Methods Twenty-eight Sprague-Dawley rats,aged 7-9 weeks,weighing 250-350 g,in which intrathecal catheters were successfully implanted without complications on 14th day after chronic post-thoracotomy pain was induced,were randomly divided into 4 groups (n =7 each):control group,the solvent dimethyl sulfoxide (DMSO) group,KATP channel opener pinacidil group (group P) and KATP channel blocker glibenclamide group (group G).10％ DMSO 10 μl,pinacidil 10 μg/10 μl and glibenclamide 50μg/10μ1 were injected intrathecally in groups DMSO,P and G at 5 day after the intrathecal catheter was implanted,respectively.Paw withdrawal threshold to von Frey filament stimulation was measured before intrathecal administration and at 10,30 and 60 min after intrathecal administration and the acetone test was performed.Coldinduced pain threshold was measured.Results There was no significant difference in paw withdrawal threshold to yon Frey filament stimulation at each time point among the four groups (P ＞ 0.05).Compared with C and DMSO groups,cold-induced pain threshold was significantly increased in group P and decreased in group G (P ＜ 0.05).There was no significant difference in cold-induced pain threshold between C and DMSO groups (P ＞ 0.05).Conclusion KATP channel in spinal dorsal horn neurons is involved in the maintenance of hyperalgesia after thoracotomy in rats.

Objective To study the expression and significance of Ezrin in triple negative breast cancer tissues .Methods We selected 102 cases ,including 24 ones of triple negative breast cancer ,58 ones of non‐triple negative breast cancer ,and 20 of benign breast disease .The expression of Ezrin in all the specimens was detected by SP immunohistochemistry .We observed whether there was any difference between the positive expression rates of Ezrin in the three groups . We also analyzed the correlation between Ezrin expression and clinicopathologic parameters of triple negative breast cancer .Results The positive expression rate of Ezrin in groups of triple negative breast cancer , non‐triple negative breast cancer , and benign breast disease was 15 .00% ,48 .28% and 75 .00% ,respectively . The difference between the three groups differed significantly ( P < 0 .01 ) . The high expression of Ezrin in triple negative breast cancer had relationship with histological grading and clinical TNM staging (P< 0 .05 ) , but not with patients' age , tumor size , or axillary lymph node metastasis ( P > 0 .05 ) . Conclusion Ezrin is highly expressed in triple negative breast cancer tissues ;therefore , it can be used as an important indicator of poor prognosis of triple negative breast cancer .

Purpose To compare the value of contrast-enhanced ultrasound (CEUS), contrast-enhanced CT (CECT) and contrast-enhanced MRI (CEMRI) in the diagnosis of renal space-occupying lesions. Materials and Methods Seventy-eight patients whose 80 kidney space-occupying lesions were conifrmed by traditional ultrasound underwent CEUS examination. Among those patients, 39 patients also underwent CECT, 28 had CEMRI, and 5 had CECT and CEMRI examination together. Taken pathologic findings as gold standard, the value of conventional ultrasound, CEUS, CECT and CEMRI was compared in the diagnosis of renal space-occupying lesions. Results Among 80 renal masses, 57 lesions were malignant and the rest 23 lesions were benign. The diagnostic sensitivity, speciifcity, positive predictive value and negative predictive value were 93.0%, 69.6%, 88.3%, 80.0%for CEUS;those for CECT were 96.4%, 72.7%, 90.0%, 88.9%respectively;and for CEMRI were 86.4%, 66.7%, 90.5%, 57.1%respectively;and the diagnostic value among the three means showed no difference (P>0.05). Conclusion CEUS, CECT and CEMRI are all effective in the diagnosis of renal space-occupying lesions, We may select suitable examination means for patients according to their features. A combination of these techniques provides more information for the diagnosis of renal space-occupying lesions.
