Objective To investigate the effect of lung volume reduction surgery （LVRS） on messenger RNA expression levels of cytoskeletal proteins in diaphragmatic muscle tissues of emphysematous rabbits. Methods A total of 40 rabbits were randomly divided into 4 groups （10 rabbits in each group） ：normal control group, emphysema group, sham operation group and LVRS group. Rabbits in control group were intratracheally administered with 0.9% normal sodium, but those in other groups were intratracheally administered with 0.4% papain at the dose of 0.5 ml/kg and inhaled cigarette smoke to induce emphysema model. Then, rabbits in emphysema group were fed routinely, however, after median sternotomy , bilateral LVRS was performed in LVRS group but not in sham operation group. The mRNA expression levels of titin and nebulin in the diaphragmatic muscles of rabbits in each group were detected by reverse transcription-polymerase chain reaction（RT-PCR）. Results Compared with control group, the mRNA expression levels of titin and nebulin in the rabbit diaphragm of emphysema groups and sham operation group decreased significantly （P〈0.01 ）, so did those in LVRS group （P〈0.05）. But it increased significantly in LVRS group compared with emphysema group and sham operation group （P〈0.05）. Conclusion LVRS can increase the mRNA expression levels of titin and nebulin in diaphragmatic muscle tissues of emphysematous rabbits, which may be the associated mechanisms at the molecular level in restoring the functions of the emphysematous diaphragm by LVRS.
The main treatment methods of macular edema (ME) are intravitreal injection of anti-vacular endothelial growth factor drugs, corticosteroids, retinal laser photocoagulation and pars plana vitrectomy (PPV). However, recurrent ME, epiretinal membrane formation and drug resistance have occurred to a part of patients, which is called refractory ME (RME). PPV with internal limiting membrane peeling (ILMP) has the potential of treating and relieving RME. PPV combined with ILMP can treat and relieve RME by removing the posterior vitreous cortex, or removing the epiretinal membrane or internal limiting membrane at the same time during surgery to relieve the traction between the vitreous body and the retina. However, due to the complex pathogenesis of ME, the therapeutic effects of PPV combined with ILMP on ME caused by different etiologies still need clinical studies to explore the best surgical methods for ME caused by different etiologies.
Objective To explore the arterial origin and the distribution of the extracranial branches of the facial nerve. Methods Red latex or red chlorinated polyvinyl chloride was injected into the arteries of 15 fresh adult head specimens by both common carotid artery catheterization. The arterial origin and distribution of the extracranial branches of the facial nerve were observed. Results The nutrient arteries of the extracranial branches of the facial nerve originated from stylomastoid artery of the posterior auricular artery, the facial nervous branch of superficial temporal artery, transverse facial artery, superior and inferior facial nervous branches of external carotid artery and the posteriorand anterior facial nervous branches of external carotid artery. The outer diameters of them were (0.8±0.2) mm, (0.9±0.4) mm, (1.9±0.3) mm, (1.0±0.2) mm, (1.1±0.4) mm, (1.0±0.2) mm and (1.1±0.6) mm respectively. The sub-branches ofthe attendant artery of the facial nerve anastomosed each other in addition to supplying their own nerve, and a rich vascular network was formed between the facial nerve and adjacent tissue. Conclusion The study on blood supply of the extracranial segment of the facial nerve can provide anatomic basis for avoiding injury of the nutrient arteries of the facial nerve during operation of the parotidean and masseteric region clinically.
Objective To improve the operative effects of patients who had tetralogy of Fallot with aortopulmonary collateral arteries (TOF-APCAs) and evaluate the clinical effects of staging and onestop hybrid approach for TOFAPCAs. Methods From January 2003 to December 2007, thirty patients with TOF-APCAs had undergone combined therapy of APCAs embolization and complete surgical repair. Fifteen patients had APCAs embolization therapy before or after TOF radical operation(staging hybrid group ); Fifteen had onestop hybrid treatment(onestop hybrid group). Results Angiography revealed that there were 19 APCAs in staging hybrid group, and of which 15(78％) were embolized successfully. Five cases had complications and one died from respiratory circulating failure. The rest all recovered and discharged. And 22 APCAs were found in one-stop hybrid group, eighteen (82％) of them were embolized successfully. Only one case had pulmonary effusion. The time of hospitalization(median 37 d vs. 22 d, P=0.011),ICU staying（median 7.0 d vs. 4.7 d,P=0.029）and endotracheal intubation（median 131 h vs. 19 h,P=0.009） was obviously longer, and the hospitalization expenses（median 64 101 [CM(159mm]yuan vs. 48 021 yuan, P=0.033）were obviously higher in staging hybrid group than that in one-stop hybrid group.And there was no statistical significance in cardiopulmonary bypass time（P=0.126） and aortic clamping time（P=0.174） between two groups. Conclusion In comparison with traditional staging hybrid approach, one-stop hybrid approach can simplify the operative process for patients who have TOFAPCAs, improve the operative successful rate and cut down expenses.
Objective To explore the influence of dexmedetomidine on wake-up test during spinal orthopaedic surgery. Methods All 80 patients taking spinal orthopaedic surgery were randomly divided into the trial group and the control group, with 40 cases in each group. The endotracheal intubation anesthesia was adopted in both groups with same anesthesia induction. Additionally, dexmedetomidine 0.8 μg/ (kg·h) was infused within 10 min in the trial group before anesthesia induction, and then another 0.5 μg/ (kg·h) was also infused from the intraoperation to suture of incision. For the control group, the same amount of normal saline was infused, and all the narcotics were stopped pumping 15 min before the wake-up test, but then were continued pumping after the wake-up test. Finally, the following indexes were analyzed: wake-up time, wake-up quality, hemodynamic changes at the time of 15 min before wake-up (T1), recovery of spontaneous breathing (T2), wake-up (T3) and 15 min after wake-up (T4), dosage of narcotics, and the incidence of adverse events. Results There was no significant difference in the operation time before wake-up between the two groups (P=0.07). For the trial group, the dosage of sevoflurane (P=0.03) and sufentanil (P=0.00) used before wake-up was significantly lower, the wake-up time (P=0.04) and bleeding amount during wake-up (P=0.00) were significantly less, the wake-up quality (P=0.03) was significantly higher, the blood pressure (P=0.00) and heart rate (P=0.00) when wake-up were significantly lower, and the incidence of adverse events (P=0.04) was significantly lower, compared with the control group. Conclusion Dexmedetomidine adopted in spinal orthopaedic surgery can significantly improve patient’s wake-up quality, shorten wake-up time, reduce bleeding amount when wake-up and adverse events after wake-up, and maintain the hemodynamic stability, so it has better protective effects.
Objective To introduce the technique of surgical patch angioplasty for the treatment of patients with isolated left main coronary artery stenosis. Methods Retrospective investigation of results of surgical patch angioplasty in patients with isolated left main coronary artery disease. Results All 8 patients who underwent left main coronary artery patch angioplasty survived with no major perioperative complications. One patient had recurrent angina and required coronary artery bypass grafting 6 months after patch angioplasty. All other patients were symptom free and had normal activity, at a mean follow-up of 5. 3 years. Conclusions Patch angioplasty can be used as an alternative surgical technique in cases of isolated left main coronary artery stenosis with no distal coronary artery disease. However, it may not be suitable for patients with significant left main coronary artery calcification.
Objective To assess the value of pulmonary ventilation test in evaluating the prognosis of cardiac surgery patients. Methods Data were collected retrospectively from consecutive patients with coronary heart disease or valvular disease, who were prepared for cardiac surgery in Zhongshan Hospital from January 2007 to December 2008. The main outcome indices were mortality of surgery, the prolonging time of using artificial airway ( ≥3 days) , and the prolonging time in intensive care units ( ICU) ( ≥5 days) . Then the relationship between the poor outcome and ventilation disorder was analyzed. Results In the 422 cases,the incidence of ventilation disorder was 55% , included 27. 5% restrictive ventilation disorder, 15. 6% obstructive ventilation disorder, and 11. 8% mixed ventilation disorder. And the severity of pulmonaryventilation disorder was mild of 34. 6% , moderate of 15. 2% , and severe of 5. 2% . Among the 42 patients who gave up surgery,50% were due to ventilation dysfunction, and the patients were prone to give up surgery with the deterioration of pulmonary function( P lt; 0. 001) . But comparing with the patients with normal pulmonary function, the risk of poor outcome after surgery did not significantly increase in the patients with ventilation disorder ( P gt; 0. 05 ) . The logistic regression analysis indicated that cardiopulmonary bypass ( CPB) was an absolute risk factor ( P lt; 0. 05) . Conclusions The incidence of ventilation disorder in patients with cardiac disease is quite high. Severe pulmonary ventilation disorder is the significant cause of giving up surgery, but may be not the absolute contraindication of cardiac surgery.
