ABSTRACT
Objective To investigate the modified method of intracavernous cannulation in monitoring intracavernous pressure (ICP) of rats.Methods The present study was conducted from October to December 2014.Twenty male Sprague-Dawley rats were randomly divided into 2 groups,the conventional group (cannulated in the crus of the penis) and the modified group (cannulated in the corporal body of the penis).The erectile function of the rats was assessed by measuring ICP/MAP (mean arterial pressure) ratio.The electrical-stimulation (ES) parameters were 5 V,15 Hz,5 ms,and 60 s for each stimulation.Results The differences in the basic ICP (14.9 ± 2.7 versus 15.5 ± 3.1 mmHg),ES-ICP (87.6 ± 7.5 versus 85.0 ± 6.2 mmHg),and ICP/MAP (71.3％ ± 6.6％ versus 72.5％ ± 6.3％) were not significant between the 2 groups (P ＞0.05 for all).Compared with the conventional group,the modified group could accurately cannulate the corpus cavernosum under direct vision,with an improved successful rate (100％ versus 80％),but there was no significant difference (P ＞ 0.05) in intracavernous pressure measurement.Conclusion The modified method of cannulating in the corpus cavernosum could have the advantage of higher successful rate,suggesting a feasible way for basic research of erectile dysfunction in rats.
ABSTRACT
The present case report was designed to summarize the clinical experience of operative technique. lung preservation, lung perfusion, and perioperative management. Of 7 cases who underwent allogenic single lung transplantation (LT), 3 were idiopathic pulmonary fibrosis, 2 were chronic obstructive pulmonary disease, 1 was silicosis, emphysema, and bulla, and I was tuberculosis in both sides and presented with destroyed lung in one side. All donors were already brain death. Donor lungs were well preserved utilizing Euro-Colins liquid or low-potassium dextran solution. Donors and recipients were matched in blood type. Of 7 cases selected,5 received single right lung transplantation, and 2 received single left LT. End-to-end anastomosis was performed for pulmonary branches and pulmonary arteries. while atrium-to-atrium anastomosis was performed for pulmonary vein. Antibiotics and immunosuppressants were routinely used prior to and subsequent to LT. Following LT, heart and lung function, usage of antibiotics, and adjustment of immunosuppressant were monitored. Stomal complications regarding bronchus and pulmonary artery and vein did not appear in any patient. Five cases survived for about 2 months, one for approximately 1 year, and one for nearly 2 years. Four cases died of multi-organ failure caused by pulmonary infection, and one of severe pulmonary hemorrhage caused by aspergillus sydowi infection. Rejection occurred in 6 cases. One case sufiered from rejection three times. Selection of indication, selection and preservafton of donor lung, LT operation and pre-and post-operative management of LT have acquired satisfactory achievements. High mortality occurred in patients with preoperative poor cardiac and pulmonary functions and postoperative severe infections accompany with application of immunosuppressant.
ABSTRACT
Objective To explore the curative mechanism of Yugong Qili Duoming Capsule for cerebral hemorrhage. Methods The model rats were established by being injected its blood to its own basal segmental, which induced cerebral bleeding. Bc1-2 was determined with immunohistochemical method and was used to evaluate the effect of Yugong Qili Duoming Capsule on the treatment group and other comparative group. Results The Bc1-2 cells in brain issue of model groups began to increase at the 1st day, reached its highest level at the 2nd day and decreased greatly at the 7th day. However, the Bcl-2 cells of the treatment group were much more than those of the model groups in the 2nd, 4th and 7th day. Conclusion Yugong Qili Duoming Capsule can increase expression of Bc1-2 in brain tissue of cerebral bleeding model rats.
ABSTRACT
<p><b>OBJECTIVE</b>To Summarize the clinical experience in the treatment of late-stage emphysema by lung volume reduction (LVR) in 5 years.</p><p><b>METHODS</b>We retrospectively studied the indications, contraindications, operation procedures and complications of LVR in 22 patients.</p><p><b>RESULTS</b>Before operation, the average FEV(1) was 24.5%, RV 196.8%, and TLC 130.5%; after operation they were 27.8%, 148.8% and 112.5%, respectively. 16 patients needed inhaling oxygen before operation, and 5 after operation. 16 patients finished 6-minute walking test with an average of 198 m, all patients walked much longer with an average of 256 m after operation. 3-degree lung function was observed in 14 patients, and 4-degree before operation in 8 patients; but 2-degree lung function in 5 patients, 3-degree in 13, and 4-degree in 4 after operation.</p><p><b>CONCLUSIONS</b>Heterogeneous type emphysema with clear target area, especially bullous emphysema is the best indication for LVR. Lung function and life quality could be much improved postoperatively. Homogeneous type could also be treated with LVR in highly selected cases. TLCO < 20% is not an absolute contraindication, others standards need further investigation. Video-assistant thoracoscopic surgery (VATS) with subaxillary small incision for LVR is safe, reliable and effective. Application of stapler buttressing with bovine pericardia could decrease air leakage postoperatively.</p>
