Objective To demonstrate in vivo that there is different degree myocardium apoptosis during acute ischemia and reperfusion and to explore prelimarily the relations between myocardium apoptosis and the expression of Bcl 2/Bax protein in rats. Methods The morphologic features of apoptotic cardiocytes were pursuited by transmission electron microscopy.DNA extracted from cardiocytes were used to identify the apoptotic DNA ladder by agarose gel eletrophoresis. DNA fragmentation was identified histochemically by TUNEL staining. Expression of Bcl 2/Bax protein in apoptotic myocardium was observed by means of immunohistochemistry and analysed by image analysis system. Results In both ischemia and reperfusion groups morphologic features of apoptotic myocardium were observed by transmission electron microscopic and the apoptotic cardiocytes were detected by the TdT mediated dUTP nick end labeling (TUNEL) staining. However, the apoptotic DNA ladder was observed only in the 2 hour reperfusion group. The reperfusion group showed a decrease in OD value of the Bcl 2 protein( P

OBJECTIVE: Previous opinions consider the secondary diffuse osteoporosis as the very cause of vertebral fractures in patients with ankylosing spondylitis (AS). However, recent studies on bone mineral density (BMD) and vertebral fractures in AS patients reveal that there is no relation between the two. This article aims at investigating the association of lumbar vertebral fractures with clinical, laboratory, and imaging indexes in AS patients.METHODS: A contrast observation was performed between 65 AS patients and 62 healthy physical examinees, whose lumbar vertebral plain radiographs were taken for checking vertebral fractures. Disease activity evaluation indexes included C-reactive protein, erythrocyte sedimentation rate, finger-to-ground distance, Schobar's index score, Bath AS radiology index (BASRI) and syndesmophyte score. Dual energy X-ray absorptiometry technique was used to measure BMD levels of lumbar vertebras and femurs.RESULTS: Out of the total 65 AS patients, 10 ones (15.4%) had lumbar vertebral fractures, with 4 ones with wedge deformities and the other 6 ones with biconcave deformities. BMD levels of Lumbar vertebras and femurs in AS patients were significantly lower than those in controls (P < 0.01). There were significant differences in Schober's index scores, finger-to-ground distance scores, Bath scores, syndesmophyta scores and intertrochanter BMD values between AS patients with and without vertebral fractures (P < 0.01 ). Multiple logistic regression analyses revealed that intertrochanter BMD values were independently associated with lumbar vertebral fractures in AS patients (P =0.043).CONCLUSION: There is a correlation between low femoral BMD levels and the risk of lumbar vertebral fractures in patients with AS, especially at the intertrochanter area.

Objective To investigate the efficacy of volume target pressure control(VTPC)and synchronized intermittent mandatory ventilation(SIMV)in treating severe neonatal respiratory distress syndrome(NRDS). Methods Fifty - six admitted cases with severe NRDS hospitalized in Jiangmen Central Hospital from October 2012 to March 2015 were randomly divided into 2 groups:28 cases in VTPC group were treated by VTPC and SIMV,and 28 cases in pressure control ventilation(PCV)group were treated by PCV and SIMV. There was no significant difference between 2 groups in terms of gender,gestational age,and birth weight(all P ﹥ 0. 05). Artery blood gas analysis was performed at 6 hours,12 hours,24 hours,and 48 hours respectively after ventilation. The following parameters were observed:the time of invasive mechanical ventilation,duration of oxygen therapy,mortality and the incidence rates of hypocapnia,pneumo-thorax,ventilator associated pneumonia( VAP),grade Ⅲ - Ⅳ periventricular intraventricular hemorrhage( PVH -IVH),periventricular leukomalacia(PVL)and bronchopulmonary dysplasia(BPD). Results No case in 2 groups withdrew from the test. There was no significant difference between 2 groups in terms of the first treatment time and total doses of poractant alfa injection(all P ﹥ 0. 05). The time of invasive mechanical ventilation in VTPC group[(71. 75 ± 9. 82)h]was shorter than that in PVC group[(97. 89 ± 16. 88)h](t = 7. 083,P = 0. 000). Hypocapnia incidence of four blood gas analysis in VTPC group[(19. 64 ± 14. 20)% ]was lower than that in PCV group[(47. 32 ± 18. 43)% ] (t = 6. 294,P = 0. 000). Incidence rates of VAP and PVL in VTPC group were lower than those in PCV group(χ2 =5. 197,P = 0. 023;χ2 = 4. 766,P = 0. 029). However,duration of oxygen therapy,mortality and the incidence rates of pneumothorax,Ⅲ - Ⅳ PVH - IVH and BPD were not significantly different between 2 groups( all P ﹥ 0. 05). Conclusion VTPC + SIMV has a better efficacy than PCV + SIMV in the treatment of NRDS.

Objective To explore DSA findings curative measures and effects of bronchial arterial embolization(BAE)of bronchiectasis with massive hemoptysis. Methods 35 patients with massive hemoptysis due to bronchiectasis were performed selective bronchial arterial DSA and BAE referring to image data of chest plain film and CT. Embolic materials were polyvinyl alcohol(PVA)and/or gelatinum sponge particles. Curative effects were followed-up for 3 months to 3 years. Results ①DSA revealed bronchial artery as being the only abnormal vessel accounted for 74.3%,bronchial artry combined with nonbronchial systemic artery as 22.9% and only non-bronchial artery involved 2.9%. Abnormal vessel number was 1 -5(mean 1.8) per case. Direct and indirect bleeding sign was displayed as 25.7% and 100% respectively. ②Curative and embolization effects were shown as 61 target vessels of 34 patients being embolized and total effective rate reaching 85.3%; of which 16 cases were adopted super-selective technique,1 case was failure of stopping bleeding for two times within 3 days,4 cases recurred within 3 months and 2 cases recurred over 3 months; with recurrent rate of 20.6%,but no serious complications such as spinal cord injury. Conclusions DSA examination and selective BAE of bronchiectasis with massive hemoptysis could provide high positive angiographic features and reliable curative effect.
