Immunohistochemical and electron microscopic techniques and image analysis were employed to investigate the regulation of cardiac AT1A and AT2 subtype receptors in rats during cardiac remodeling following myocardial infarction (MI). Positive immunostaining for AT1A and AT2 receptors was observed in myocytes and vessels with AT1A being more than AT2. Three days after MI, disappearance of myocardial cross striation and fibroblast hyperplasia were found with electron microscopy. AT1A receptor protein expression in myocardial noninfarcted portion notably increased compared with that in sham-operated control rats (P<0.001). No apparent changes were observed in AT2 receptor (P>0.05). Two weeks after MI, myocyte cross striation and collagen deposition were found. Meanwhile, AT1A receptor staining decreased compared with that of three days after MI (P<0.01), but there was still more than that of the control (P<0.05). AT2 receptor was significantly increased compared with that of the sham-operated control rats (P<0.001). These results suggust that both AT1A and AT2 receptor protein expression was upregulated in noninfarcted myocardium after MI, and the regulation of AT1A and AT2 receptors after MI may be involved in post-infarction cardiac remodeling.

Objective To observe the anatomic and imaging morphology ofjugnlar bulb and its relationship with the surrounding structures, and to investigate the classification ofjugnlar bulb and its clinical significance. Methods We dissected 30 human temporal bones and studied multi-slice spiral CT imaging data of temporal bone of 120 cases and blood vessel cast mould specimen of the jugular bulb of 6 cases, to observe the morphology of jugnlar bulb and its spatial relationship with the surrounding structures. We made an imagined sagittal plane on the medial well of the tympanic cavity, with a horizontal tangent line of the proximal wall of the tympanic cavity and a vertical tangent line of the posterior wall of the tympanic cavity as coordinate axes (X axis and Y axis), respectively, so the 4 quadrants ( Ⅰ , Ⅱ, Ⅳ, Ⅳ) were formed. The jugular bulb was classified intro 4 types according to the quadrant where its top was projected and subtyped according to its position on the inner or outer side of the plane. The operation via mastoid approach was simulated on specimen to observe the effect of jugnlar bulb on the operation route. Results Some jugular bulbs were flat type and others were prominent types. The classification in the group of CT image: type Ⅰ , 11 case (9%);type Ⅱ, 63 cases (53%);type Ⅲ, 25 cases (21%);type Ⅳ, 21cases (17%). The classification in the group of specimen: type Ⅰ, 1 case (3%);type Ⅱ, 11 cases (37%);type Ⅲ, 8 cases (27%);type Ⅳ, 10 cases (33%). Each type of the jugular bulb had different effects on the operative approach. Conclusions The classification method with the 4 quadrants is a simple and three-dimensional way to describe the position of the jugular bulb for imaging diagnosis or operative scheme design.

OBJECTIVETo investigate CT and MRI characteristics of primary spinal large B cell lymphoma.
METHODSCT and MRI data of 23 patients with primary spinal large B cell lymphoma confirmed by histopathology were retrospectively analyzed from March 2011 to August 2015. Among them, including 14 males and 9 females aged from 28 to 70 years old with an average of 53.4 years old. The clinical manifestation mainly focus on pain around spinal and minority peripheral nerve symptom. The courses of disease ranged from 2 weeks to 3 months with an average of 9 weeks. Nine patients underwent CT plain scan, 8 patients underwent plain and enhanced CT; 21 patients underwent MRI plain scan and enhanced; 15 patients underwent CT and MRI examination. The location, bone changes, shape, density, signal intensity and enhancement characteristics of lesions were observed and compared with pathology.
RESULTSLocation and size of lesion showed cervical vertebrae in 1 case, thoracic vertebrae in 16 cases, lumbar vertebrae in 2 cases, and sacral vertebrae in 4 cases. Mass was larger, the largest cross-sectional size of group was up to 73 mm× 125 mm. CT examination showed that 11 cases with "cloud and mist" shape change, 6 cases with compression fractures, and with "floating ice" shape change, 9 cases with "oversleeve" shape change, 11 cases with spinal stenosis; enhancement scan showed obvious reinforcement. MRI showed slightly low signal on T1WI and T2WI were slightly high signal, and signal was uneven, and enhancement scan showed obvious reinforcement, 13 of 16 cases with spinal canal stenosis changed like "oversleeve", intervertebral space showed no significant stenosis. Comparison of CT and MRI showed the manifestation of bone destruction by CT was superior than that of MRI, but the range of lesion, and related surrounding structures were not better than MRI. MRI displayed the range of lesion usually bigger than CT. Pathology results showed that 23 patients were all primary spinal large B cell lymphoma.
CONCLUSIONSPrimary spinal large B cell lymphoma has certain features in age, location and imaging findings. The "cloud and mist", "floating ice" and "oversleeve" shape bony destruction by CT and MRI has certain significance to diagnosis of primary spinal large B cell lymphoma.

OBJECTIVETo evaluate the surgical therapeutic strategy and prognostic factors for non-small cell lung cancer (NSCLC) with mediastinal lymph node metastasis (N2).
METHODSThe survival rate of 117 patients with N2 NSCLC treated surgically from January 1999 to May 2003 were analyzed. There were 88 male cases and 29 female cases, aged from 29 to 79 years. The procedure of operation (lobectomy, pneumonectomy and palliative resection), histological classification (squamous cell carcinoma, adenocarcinoma, mixed carcinoma, and large cell carcinoma and others), T primary tumor status, and adjuvant therapy were analyzed to determine their impact on the 5-year survival rate.
RESULTSThe median survival time was 22 months, and the over-all 3- and 5-year survival rate was 28.1% and 19.0%. Survival was higher in patients with lobectomy than with palliative resection, with T1 and T2 than with T4. The 5-year survival rate had no deference in age, sex and different histological classification. The 5-year survival rates of lobectomy and pneumonectomy (22.2% and 25.0% respectively) was higher than palliative resection (9.1%).
CONCLUSIONSSurgical procedures (especially lobectomy) is the best choice for N2 NSCLC patients with T1 or T2. But it can not prolong T4 patients' life significantly.

OBJECTIVETo investigate whether terbutaline affects alveolar liquid clearance after oleic acid-induced lung injury in rats.
METHODSForty healthy Wistar rats (weighing 250-280 g) were randomly divided into five groups (n=8 in each group): the normal control group (control group), oleic acid injury group (injury group), terbutaline-treated group (terbutaline group), terbutaline plus amiloride-treated group (terbutaline+amiloride group) and terbutaline plus ouabain-treated group (terbutaline+ouabain group). Acute lung injury model was induced by intravenous oleic acid (0.25 ml/kg body weight). 24 hours later, 1.5 microCi (125) I-labeled 5% albumin solution (5 ml/kg body weight) was dripped into the lungs through trachea. The alveolar liquid clearance rate, extravascular lung water content, and arterial blood gas were measured 1 hour thereafter.
RESULTSAt 24 hours after infusion of oleic acid, the rats developed pulmonary edema and severe hypoxemia, with the alveolar liquid clearance rate decreased by 49.2% and the extravascular lung water content elevated by 47.9%. Compared with the rats in the injury group, terbutaline (10(-4) mol/L) significantly increased the alveolar liquid clearance rate, decreased the extravascular lung water content and improved hypoxemia. The effect of terbutaline was partly blocked by amiloride and ouabain, which were inhibitors of sodium transport. Terbutaline increased the alveolar liquid clearance rate by 63.7%, and amiloride and ouabain reduced the alveolar liquid clearance rate by 54.7% and 56.8%, respectively.
CONCLUSIONSTerbutaline can accelerate alveolar liquid clearance through increasing sodium transport to attenuate pulmonary edema, thus improving gas exchange, which may have therapeutical effect on pulmonary edema after acute lung injury.
