OBJECTIVETo study the rehabilitation effects ergometry on COPD patients.

METHODSThirty COPD out-patients in our Hospital were randomly divided into 2 groups. Rehabilitation group, 15 patients, performed leg ergometry exercise of 80% peak Watt x 30min/d x 3d/w x 12w. Another 15 patients were control group without exercise. All patients received conventional therapy. Pulmonary function testing (PFT), cardiopulmonary exercise testing (CPET), arterial blood gas analysis (ABG), Borg and CAT sores were done at both baseline and 12 w.

RESULTSThere was no statistically difference in lung function testing, blood gas analysis and cardiopulmonary exercise test when pre- exercises between 2 sub-groups. The IC, peak VO2 and peak, W of rehabilitation group significantly increased (P < 0.05); and Borg and CAT.scores significantly decreased (P < 0.05) from baseline; and other PFT and ABG did not change (P > 0.05). While there was no difference in control group (P > 0.05).

CONCLUSIONLeg submaximal ergometry rehabilitation improves health condition and ameliorate dyspnea symptoms in COPD patients.

Using the mongolian gerbil model of transient forebrain ischemia by bilateral carotid arteries occlusion, the levels of phosphorylation and the amount of DARPP-32 in striatum were measured by back-phosphorylation and Western-blotting assay in vitro. Transient forebrain ischemia had no effect on the immunoreaction of DARPP-32 in striatum, but the state of phosphorylation of DARPP-32 showed a significant change. The ［32P］ phosphate incorporation in DARPP-32 decreased after 2, 7 or 10 min of ischemia, but increased after a 5-min ischemia. In contrast, the result of back-phosphorylation in vivo was opposite to that obtained in vitro.

Objective To explore the endoscopic and clinicopathological characteristics of upper gastrointestinal tract metastasis,it can improve the diagnosibility of endoscopists and pathologists. Methods Three cases of upper gastrointestinal tract metastasis and seven cases in the related literature were studied, and its endoscopy and clinicopathological findings were analyzed with a review of the literature, whose gastrointestinal symptoms were the first manifestation. Results Case 1 endoscopic detection of esophageal ulcer lesions, pathological diagnosis of metastatic cancer, considering the source of the lung, confirmed by imaging examination; Case 2 showed that the gastric body was prominent, and the pathological diagnosis was squamous cell carcinoma. It was suggested that the clinical examination should be carried out without metastasis, and then confirmed by imaging examination and bronchoscopy biopsy; Case 3 endoscopic examination revealed multiple polypoid lesions in the stomach and duodenum, and was pathologically diagnosed as metastatic renal cell carcinoma. 3 patients were correctly diagnosed, thus avoiding unnecessary radical surgical treatment. 7 cases of patients in the literature were aged, they were also in a variety of gastrointestinal symptoms and the first diagnosis, no previous history of cancer, endoscopic lesions in the stomach or duodenum, supplemented by immunohistochemical staining in pathological diagnosis were diagnosed as metastases, the primary tumor site without organ specific. Conclusion The metastasis of upper gastrointestinal tract is rare, especially when the gastrointestinal symptoms were the first manifestation,it is usually missed and misdiagnosed. The diagnosis relies on the endoscopic and pathological examination, supplemented by the imaging examination, so the patients could get effective treatment in time.

BACKGROUNDDifferential diagnosis of isolated calf muscle vein thrombosis (ICMVT) and gastrocnemius hematoma is essential for early identification of deep vein thrombosis (DVT). This study aimed to investigate the diagnostic value of high-frequency color Doppler ultrasound for differential diagnosis of ICMVT and gastrocnemius hematoma.

METHODSA retrospective case series of 35 ICMVT (M:F, 21:14; mean age (64.5 ± 10.6) years) and 23 gastrocnemius hematoma (M:F, 16:7; mean age (75.4 ± 11.8) years) patients with bilateral/unilateral lower limb pain was conducted between January 2006 and September 2012. Characteristics and the morphology of high-frequency color Doppler ultrasonography of the lower limb deep vein, great saphenous vein, calf muscles, skin, and soft tissue were examined.

RESULTSICMVT hypoechoic signals were characterized by long, tube-like masses on longitudinal sections and oval masses on transverse sections, with apparent muscle thrombosis boundaries, distal and proximal venous connections, and, often, lower limb DVT. Gastrocnemius hematoma hypoechoic signals were characterized by large volumes, enhanced posterior hematoma echo, hyperechoic muscle boundaries, no hematoma blood flow, and no DVT, and clear differences in trauma/exercise- and oral anticoagulant-induced hematomas were readily apparent. According to the measurement, the ratio of long diameter/transverse diameter (D/T) in ICMVT patients was about less than 2.0, whereas in gastrocnemius hematoma patients the ratio was more than 2.0. Early stage isoechoic and hypoechoic signals were detected with gradually increasing ovular anechoic areas. Partial muscle fibers in the hematoma due to muscle fractures were apparent.

CONCLUSIONHigh-frequency color Doppler ultrasound was found to be a sensitive and reliable method for differential diagnosis of ICMVT and gastrocnemius hematoma due to trauma and exercise or prolonged oral anticoagulant use.

OBJECTIVETo investigate the effects of di-(2-ethylhexyl) phthalate (DEHP) on the expressions of Caspase-3 and Caspase-9 genes in rat Leydig cells and the apoptosis of the cells in vitro.

METHODSLeydig cells were isolated from male SD rats, primarily cultured and treated with DEHP at a low (10 nmol/L), a medium (50 nmol/L) and a high dose (100 nmol/L) for 24 hours. Then the mRNA expressions of Caspase-3 and Caspase-9 genes in the Leydig cells were detected by real time PCR, their protein expressions determined by Western blot, and the apoptosis of the Leydig cells measured by flow cytometry.

RESULTSCompared with the DMSO control group, the low-, medium- and high-dose DEHP groups showed significantly upregulated expressions of Caspase-3 mRNA (1.69 +/- 0.38 vs 3.82 +/- 0.39, 6.91 +/- 0.40 and 15.47 +/- 0.40, P < 0.05), Caspase-3 protein (0.18 +/- 0.0.09 vs 0.32 +/- 0.10, 0.61 +/- 0.08 and 0.89 +/- 0.09, P < 0.05), Caspase-9 mRNA (2.24 +/- 0.41 vs 5.16 +/- 0.43, 9.61 +/- 0.45 and 19.22 +/- 0.43, P < 0.05) and Caspase-9 protein (0.26 +/- 0.07 vs 0.40 +/- 0.08, 0.68 +/- 0.09 and 0.96 +/- 0.08, P < 0.05), as well as increased apoptosis rate of Leydig cells (4.36 +/- 1.11 vs 7.52 +/- 1.09, 12.72 +/- 1.10 and 24.59 +/- 1.11, P < 0.05), all in a dose-dependent manner.

CONCLUSIONDEHP can induce the apoptosis of rat Leydig cells by activating the apoptosis Caspase pathway, and consequently affect the function of Leydig cells.

OBJECTIVETo investigate the mechanical character, microleakage and mineralizing potential of nano-hydroxyapatite (nano-HAP)-added glass ionomer cement(GIC).

METHODS8% nano-HAP were incorporated into GIC as composite, and pure GIC as control. Both types of material were used to make 20 cylinders respectively in order to detect three-point flexural strength and compressive strength. Class V cavities were prepared in 120 molars extracted for orthodontic treatment, then were filled by two kinds of material. The microleakage at the composite-dentine interface was observed with confocal laser scanning microscope (CLSM) after stained with 1% rhodamin-B-isothiocyanate for 24 hours. Class V cavities were prepared in the molars of 4 healthy dogs, filled with composite, and the same molars in the other side were filled with GIC as control. The teeth were extracted to observe the mineralizing property with polarimetric microscope in 8 weeks after filling.

RESULTSThree-point flexural strength and compressive of nano-HAP-added GIC were increased compared with pure GIC (P < 0.001, P < 0.05). The nanoleakages and microleakages appeared at the material-dentine interface in the two groups, but there were more microleakages in control group than in experiment group (P = 0.004). New crystals of hydroxyapatite were formed into a new mineralizing zone at the interface of tooth and nano-HAP-added GIC, while there was no hydroxyapatite crystals formed at the interface of tooth and pure GIC.

CONCLUSION8% nano-HAP-added GIC can tightly fill tooth and have mineralizing potential, and can be used as liner or filling material for prevention.
