Objective To summarize the methods of repairingthe urethral defect in the penis of an adult and the clinical application of the island skin flaps of the scrotum septum to the reparative treatment. Methods From January 2000 to November 2005, twenty-six cases of urethral defect in penis, including 16 cases of congenital urethral defect, 6 cases of traumatic urethral defect in middle penis, and 4 cases of distal urethral defect, were repairedby the local penis fascia flaps.The island skin flaps of the scrotum septum were transferred to cover the penis wound. The pedicle contained the artery of the posterior scrotum and the artery of the anterior scrotum. The flap taken from the scrotum septum was 2.5 cm×5.5 cm in area. Results After a follow-up of 7months to 4 years, all the 26 patients had the healing of the first intention without urethral fistula, urethral narrowness or penis curvature, except 4 patients who developedinfection and leakage of urine, but the wounds healed spontaneously 2-4 weeks after operation. Conclusion The penis fascia flaps and the island skin flaps of the scrotum septum can be used to repair the urethral defect in the penis of an adult. The blood supply to the flaps is sufficient and all theflaps can survive well. A good shape and function of the penis can be obtained.
ObjectiveTo investigate the efficacy and safety of the phase Ⅰ corpus callosotomy in the treatment of adult refractory epilepsy. MethodsWe conducted a retrospective analysis of 56 adults with intractable epilepsy in Tangdu Hospital from January 2011 to July 2016.All patients were treated for the phase Ⅰ total corpus callosotomy, followed up 1~5 years after surgery. Results14 cases (25.0%) patients achieved complete seizure free after surgery, 19 cases (33.9%) whose seizures reduced more than 90%, 10 cases (17.9%) reduced between 50%~90%, 7 cases (12.5%) between 30%~50%, 6 cases (10.7%) decreased below 30%; Drop attacks of 47 cases (83.9%) patients disappeared. Postoperative complications occurred in 13 cases(23.2%), and most of them recovered well. 5 cases(8.9%) had long-term sensory disassociation, no serious complications and death. The percentage of patients reporting improvement in quality of life was 67.9%. ConclusionsFor patients with intractable epilepsy who can not undergo focal resection, Ⅰ phase total corpus callosotomy has a certain effect on reducing seizure frequency, eliminating drop attacks, and improving the quality of life.
ObjectiveTo discuss whether there are some psychological changes in adult women patients when they first wear fixed orthodontic appliances. MethodsEighty adult women patients aged between 18 and 50 years old averaging 35, receiving fixed orthodontic treatment between January 2011 and August 2012 were selected as our study subjects. They completed a questionnaire regarding anxiety and depression at the first day when they came to the hospital and 7 days, one month, and three months after fixed appliance placement respectively. The scales of anxiety and depression of subjects were assessed according to the symptom checklist-90 (SCL-90). ResultsCompared with the norms, the SCL-90 scores of anxiety, depression and interpersonal relationship sensitivity were higher in these patients. The symptoms were more severe a week later, and were even more severe one month after the appliance placement. Three months later, the scores of all factors began to fall, but were still higher than those before the treatment. ConclusionThere is a certain extent of negative psychological influence on adult women patients during fixed orthodontic treatment. At the first week after the placement of fixed appliance, adult women patients may suffer from anxiety and depression.
Objective To discuss venous drainage types of median hepatic lobe and their guiding significances on the selection of grafts. Methods Between April 2005 and March 2009, 109 potential living donors underwent 3-dimensional reconstruction of computed tomography (CT) and the volume of graft was determined in the center of organ transplantation of Ruijin Hospital. The venous drainage types of median hepatic lobe of each donor were analyzed by the computer-based liver operation-planning system in detail to assign middle hepatic vein (MHV) types according to Marcos classification and venous types of Ⅳb segment according to Nakamura classification. Results The branching pattern of MHV was divided into 3 types: Type Ⅰ and Ⅱwere relatively more accounting for 44.0% （48/109）, 37.6% （41/109）, and type Ⅲ was fewest 〔18.3% （20/109）〕. There were no significant differences in volume of whole liver, volume of left liver or left liver/total liver volume ratio among various types of MHV of the donor (Pgt;0.05). Ⅳb vein was also divided into 3 types: The most common was type Ⅰ, accounting for 72.4% (79/109); Type Ⅱ 〔12.8% （14/109）〕, type Ⅲ 〔14.7% （16/109）〕 were relatively fewer. At last, 37 donors provided right liver, for Marcos Ⅰ, Ⅱ, and Ⅲ type of donors, donors remained with MHV was 12/17, 8/11, and 5/9; for Nakamura Ⅰ, Ⅱ, and Ⅲ type of donors, those number were 16/26, 4/6, and 5/5. Conclusion In adult-to-adult living donor liver transplantation, there may be great significances in accordance with Marcos and Nakamura typing results to harvest right lobe liver graft with or without MHV.
Objective To summarize the clinical experiences of venoarterial extracorporeal membrane oxygenation (ECMO) which provides temporary cardiopulmonary assist for critical patients, and preliminary analysis of the cause of failure. Methods From February 2005 to October 2008, 58 adult patients (male 42, female 16) undergoing cardiogenic shock required temporary ECMO support. Age was 44.8±17.6 years, and support duration of ECMO was 131.9±104.7 hours. There were 24 patients (41.4%) with coronary heart disease, 11 patients (19.0%) with cardiomyopathy, 10 patients (17.2%) with cardiac valve disease,and 9 patients (15.5%) with congenital heart disease. Results 22 patients died in hospital. 11 patients (50%) died of multisystem organ failure, 5 patients (22.7%) died of refractory heart failure despite the ECMO support. Another patients died of bleeding and severe pulmonary hypertension etc. The percentage for patients need cardiac resuscitation before ECMO support and patients with acute renal failure treated by continuous renal replacement therapy (CRRT) under ECMO support were obviously higher in dead patients than those in survivor patients (45.5% vs.19.4%, 40.9% vs. 5.6%; P=0.043，0.001). All of the discharged patients were reassessed, mean followup time were 15.6 months. Three patients died of refractory heart failure， 1 patient died of neurologic complications. The other 32 survivors were in good condition with cardiac symptom of New York Heart Association class Ⅰ or Ⅱ. Conclusion ECMO offers effective cardiopulmonary support in adults. Early intervention and control of complications could improve our results with increasing experience. Combining using CRRT during the ECMO support is associated with significantly higher mortality rate. Suffered cardiac arrest prior to ECMO also influences the survival.
Objective To study the effect of two cytokines, basic fibroblast growth factor(bFGF) and insulin-like growth factor-I(IGF-I), on cell proliferation in chondrocytes of adult rabbits. Methods The primary chondrocytes of adult rabbits were harvested and cultured with bFGF and IGF-I at different concentrations,respectively, as well as with the mixture of the two cytokines; the quantity of cultured chondrocytes was detected by MTT assay at the 24th, 48th and 72th hours; and the final fold increase of different groups was measured by cell count for the 3rd passage; and the proliferation index of the groups was recorded by flowing cytometer on the 14th day. Results ① The cultured chondrocytes with either bFGF, IGF-I or their mixture were significantly more than that of control group at the 24th, 48th and 72th hours (P＜0.01). ② After the 3rd passage, the final folds of proliferation were significantly higher in the groups with cytokinesthan in the control group (P＜0.01); and the final fold with the mixture ofcytokines was significantly higher than that of both IGF-I and bFGF (P＜0.01). ③ Theproliferation index was significantly higher in the groups with cytokines than in the control group (P＜0.01); the proliferation index with the mixture of cytokines was significantly higher than that of both IGF-I and bFGF (P＜0.05); besides, proliferation index was higher when cytokine was applied twice than once (P＜0.05). Conclusion bFGF and IGF-I could promote chondrocytes proliferation of adult rabbits obviously and they are synergistic in cell proliferation.
Objective To investigate the long-term clinical results of treatment of adult unicameral bone cyst with cancellous allograft. Methods From 1993 to 1998, 15 patients with unicameral bone cyst were treated by allograft with lyophilized cancellous bone. Among 15 patients, there were 5 males and 10 females, aging 19-41 years with an average of 27 years. The average follow-up time was 7.5 years (6-11 years). The X-ray films were taken and the CT scanning were carried out. Results The X-ray films showed that the allograft particles became vague 2-3 months after operation, that the allograft particles fused and began to form new bone and the bone density increased 5 months after operation, and that new bone formation completed after 7 months of operation. At the end of follow-up, remodelling in new bone occurred. Reoccurrence was not found in all patients. The symptom of pain disappeared or relieved obviously. Conclusion Allograft of lyophilized cancellous bone is an effective treatment for adult unicameral bone cysts.
Abstract: Objective To evaluate the longterm results of surgical treatment of tetralogy of Fallot (TOF) in adults and discuss the perioperative treatment skills. Methods From January 2000 to March 2008, 149 patients older than 14 years with tetralogy of Fallot received surgical treatment in Changhai Hospital. Among the patients, there were 78 males and 71 females with ages ranged from 14 years to 53 years and the average age was 26.3 years. Twenty patients had previous pulmonary arterial shunts before radical treatment. A total of 129 patients underwent primary radical treatment. Thirtyeight patients received a right ventricular outflow tract patch, 107 patients had transannular patch, and 4 patients had homograft aorta with valves. Results Hospital mortality was 4.0%(6/149). Four patients died of low cardiac output syndrome (LCOS), and multiple organ failure, and 2 patients died of acute renal failure. The postoperative complications included pleural effusion in 11 patients, pulmonary edema in 10 patients, severe LCOS in 9 patients, severe cardiac arrhythmia in 7 patients, reoperation for excessive bleeding in 7 patients, reintubation in 6 patients, and residual ventricular septal defect (VSD) in 5 patients (two of them had reoperation for residual VSD repair and 2 received transcatheter closure of VSD). One hundred and thirtyfour patients were followed up for 3 to 102 months (47.2±28.6 months) with a followup rate of 93.7%(134/143). Late death occurred in 2 patients, one of whom died of secondary infective endocarditis and the other had a sudden death 29 months after operation. During the followup, one patient had residual VSD (2 mm), but had a normal life. The peak systolic right ventricletopulmonary artery pressure gradient exceeded 40 mmHg in 4 patients. Two patients had severe pulmonary regurgitation. A total of 132 patients survived and had an improved life. One hundred and twentyone patients had class Ⅰ heart function (NYHA), and 11 patients in class Ⅱ. Conclusion The pathophysiologic conditions of the patients with tetralogy of Fallot in adults are very complicated due to longterm right ventricle outlet stricture and chronic hypoxia. Preoperative evaluations and postoperative treatment of complications are necessary. The systemicpulmonary arterial shunts should be performed when hypotrophy of the pulmonary arteries or left ventricles exists. Repair of tetralogy of Fallot in adults has acceptable morbidity and mortality rates with goodlongterm outcomes.
ObjectiveTo evaluate tip location of peripherally inserted central catheter (PICC) by using the carina as evaluation mark, so as to provide clinical references for blinding manipulation of PICC. MethodsA retrospective analysis about the effects of tip location of PICC by using the carina as evaluation mark on inpatients with malignant tumour was conducted in tumour centre of the West China Hospital from March 2013 to April 2014. Chest X radiography was applied to evaluate the tip location of PICC. Statistical analysis was performed using SPSS software (version 19.0) and the outcomes were presented by frequency and percentage. ResultsA total of 612 cases of blinding manipulation of PICC were evaluated, of which, 502 (82%) were located in the central venous and 110 (18%) were located in the noncentral venous. The numbers of those with the catheter tips located in the non-central venous were 38 in the right atrium, 33 in the internal jugular vein, 24 in the innominate vein, 8 in the axillary vein, and 7 in the subclavian vein, respectively. ConclusionThe effects of blinding manipulation of peripherally-inserted central catheter by using the carina as evaluation mark are relatively good. But it still needs to be improved.
To evaluate the development prevention and treatment of pneumonic injury after operation on aged patients with abdominal infection. We analyzed 77 aged patients (＞60 y) admitted from Jan. 1991 to Dec. 1992: 38 cases of which with abdominal infection (infection group), 39 cases without abdominal infection (non-infection group). All patients were given oxygen therapy and continuous SaO2 monitoring. Results: There were 28 patients with hypoxemia (SaO2＜95%) in infection group, with an occurrence rate of 73.7%. In non-infection group (12 patients), the rate of hyoxemia was 30.8%, which has significant difference between two groups (Ｐ＜0.001). All patients with hypoxemia were given oxygen therapy and 31 patients′ SaO2 was elevated. The efficient rate was 77.5%. Other 9 patients developed ARDS, the rate was 2.5% (9/40). In the infection group 8 patients developed ARDS with an occurrence rate of 21.1%. There was one patient with ARDS in the non-infection group, the rate was 2.6%. There was significant difference between two group (Ｐ＜0.05). Conclusions: The results suggest that hypoxemia is liable to occur in aged patients with abdominal infection after operation and these patients were liable to develop ARDS. Oxygen therapy and SaO2 monitoring is the important managements to these patients in prevention of pneumonic injury.
