Objective To explore the clinical curative effects of hip replacement in the treatment of femoral neck fracture and femoral head necrosis in elderly patients and the existing problems.Methods A total of seventy-five aged patients with femoral neck fracture or femoral head necrosis who were treated by hip replacement were selected as study objects.They were divided into fracture group and femoral head necrosis group according to disease type,all the patients were treated with hip replacement.The surgical time,intraoperative blood transfusion volume,length of hospital stay,in-bed time,perioperative complications and postoperative complications were observed and recorded.The Harris score was used to evaluate hip function of preoperation and postoperation.Results All patients were followed up for 6 ～ 24 months,no incision infection and severe perioperative complications.The volume of intraoperative blood loss,operation time,hospitalization time,in-bed time of the fracture group were (334.9 ± 90.4) mL,(91.7 ± 14.3) min,(19.5 ± 7.5) d,(5.9 ± 1.6) d,respectvely,which of the femoral head necrosis group were (362.9 ± 71.5) mL,(93.5 ± 7.8) min,(20.5 ± 4.2) d,(6.3 ± 1.4) d,respectvely,the differences between the two groups were not statistically significant (all P ＞ 0.05).At the end of the follow-up,the Harris scores of the two groups were higher than before operation,and the score of the fracture group (89.0 ± 7.4) points was significantly higher than (84.0 ± 9.2) points of the femoral head necrosis group (t =19.639,P ＜ 0.05).In the fracture group,1 year after surgery,1 patient appeared delayed fracture healing,2 cases with postoperative pain when walking the affected area.In the femoral head necrosis group,1 case with femoral nerve injury,1 case of death due to its original diseases,1 case of postoperative sore pain when walking,the two groups had no prosthesis loosening or dislocation phenomenon.Conclusion Hip replacement in the treatment of femoral neck fracture and femoral head necrosis in elderly patients can be used as a clinical treatment option with short in-bed time,less intraoperative blood loss,short operation time,less perioperative complication and good treatment effect,and it is worth to be promoted.

AIM: To study the effect of IL-12 on T lymphocytes apoptosis, the expression of Fas/FasL and TNFR/TNF?. METHODS: Terminal dUTP nick end labeling(TUNEL) and Annexin V assay were used. Anti-TNFR were labeled with FITC, anti-CD95 was labeled with PE and Anti-FasL with biotin. Three kinds of T cells (HTB176,TIB152 and human normal T cells) were analysed through flow cytometry. RESULTS: At 1st hour after being treated with IL-12, the expression of FasL protein and FasL mRNA in HTB176 and TIB152 began to increase and reached peak value in 24 hours. In the normal T cells, FasL just began to increase in 1 hour and maintained stability in 6, 12 and 24 hours through the later experiment period. All three kinds of T cells displayed no change in the expression of CD95 and TNFR/TNF? under the stimulation of IL-12. CONCLUSION: Expression of such apoptosis regulating factors were different in the apoptosis of T cells induced by IL-12.

Objective: To investigate the efficacy of multistage surgery in patients with functional single ventricle (FSV) and risk factors of postoperative death. Methods: The clinical data of all consecutive patients with FSV undergoing multistage single ventricle palliation surgery in Guangzhou women and children's medical center from January 2008 to December 2017 were retrospectively reviewed. The study included 289 patients. The age was 10.0 (6.0, 35.4) months,and there were 198 male and 91 female patients. The patients were followed up at outpatient clinic. Survival rates were calculated with Kaplan-Meier. Multivariate Cox regression analysis was made to determine the risk factors of postoperative death. Results: Seventy-nine patients required the first stage palliation surgery, 232 patients received the Glenn shunt surgery, and 162 patients completed the Fontan procedure. Overall, postoperative death occurred in 39 patients including 21 after the first stage palliation surgery (early stage 13 cases, late stage 8 cases) , 10 after the Glenn shunt surgery (early stage 5 cases, late stage 5 cases) , and 8 following the Fontan procedure (early stage 6 cases, late stage 2 cases) . Kaplan-Meier analysis showed that survival rate of the entire cohort was 90.2% (95%CI 86.7%-93.7%) , 85.9% (95%CI 81.8%-90.0%) ,and 84.6% (95%CI 79.7%-89.5%) at 1 year, 5 years and 10 years post operation. Survival rate was 74.4% (95%CI 64.8%-84.0%) , 73.0% (95%CI 63.2%-82.8%) , and 73.0% (95%CI 63.2%-82.8%) at 1 year, 5 years, and 10 years post the first stage palliation surgery, 97.8% (95%CI 95.8%-99.7%) , 95.2% (95%CI 92.3%-98.1%) , and 95.2% (95%CI 92.3%-98.1%) at 1 year, 5 years, and 10 years post Glenn shunt surgery, 95.6% (95%CI 92.5%-98.7%) and 93.7% (95%CI 88.8%-98.6%) at 1 year and 5 years post Fontan surgery. Multivariate Cox regression analysis revealed that total anomalous pulmonary venous connection (HR=5.47, 95%CI 2.71-11.04, P<0.001), atrioventricular valve regurgitation more than moderate (HR=2.52, 95%CI 1.32-4.79, P=0.005), systemic ventricular outflow tract obstruction (HR=3.47, 95%CI 1.30-9.29, P=0.013), and required the first palliation surgery (HR=3.12, 95%CI 1.59-6.15, P=0.001) were risk factors of postoperative death. Conclusions The multistage surgery can effectively improve the survival of patientswith functional single ventricle and is associated with satisfactory long-term prognosis. Total anomalous pulmonary venous connection, atrioventricular valve regurgitation more than moderate, systemic ventricular outflow tract obstruction, and required the first palliation surgery are risk factors of postoperative death in these patients.

Objective: To review the early and mid-term results of end-to-side anastomosis technique for interrupted aortic arch in neonates and infants. Methods: Clinic data of 46 patients were diagnosed as interrupted aortic arch in Department of Cardiac Surgery, Guangzhou Women and Children′s Medical Center between January 2010 and December 2016 were analyzed retrospectively. Twenty-six cases were neonates. The median age underwent surgery was 23 days (range: 2 days to 8 years). Anatomical subtypes included 36 cases of type A and 10 cases of type B. There was no type C case. The reconstruction of the aortic arch was completed by an extended end-to-side anastomosis technique between the descending aorta and the undersurface of the proximal aortic arch. In 42 patients, all with intracardiac anomalies, had concomitant complete repair of intracardiac anomalies through a median sternotomy. The remaining 4 patients, all without intracardiac anomalies, an end-to-side anastomosis was constructed through a left thoracotomy. During follow-up, aortic arch recurrent obstruction, left ventricular outflow tract obstruction (LVOTO) and tracheal stenosis were focused. Results: There were 3 surgical deaths, with amortality rate of 6.5%. The remaining 43 patients survived after surgery. In 39 of these patients, deep hypothermic cardiac arrest (DHCA) strategy was used for brain protection, and the mean time of DHCA was (16±3) minutes. Eight patients underwent delayed sternal closure. The mean mechanical ventilation time and ICU stay time were (3.4±1.6) days (range: 2 to 12 days) and (6.4±2.7) days (range: 3 to 16 days) respectively. In 16 patients, all with tracheal or bronchial stenosis before surgery, mechanical ventilation was successfully evacuated, and no new airway stenosis occurred. There was no residual pressure difference between upper and lower extremity arterial blood pressure at discharge. Echocardiography showed normal arterial blood flow velocity in aortic arch. At a mean follow-up of (36.2±18.9) months (range: 6 months to 7 years), there were two patients lost and one late date. Four patients developed a recurrent stenosis at the aortic arch, of which two were severe, and the other two were mild. In 2 patients, both with mild LVOTO before surgery, no significant increase in the degree of obstruction was found during the follow-up. Two patients developed new mild to moderate LVOTO without clinical symptoms, and continued to follow up. In all patients, the tracheal or bronchial stenosis were extenuated, and there was no new progressive airway stenosis by regular bronchoscopy. Conclusions The end-to-side anastomosis technique for the reconstruction of the aortic arch achieved excellent early and mid-term results in neonates and infants suffered from interrupted aortic arch. Reducing the anastomotic tension by extensive mobilization is the key to prevent postoperative early complications and late recurrent arch obstruction.

Objective: To evaluate the early- and mid-term outcomes of surgical atrioventricular valve (AVV) intervention in patients with functional single ventricle (FSV). Methods: The clinical data of 40 consecutive FSV patients who underwent surgical AVV intervention between January 2008 and December 2017 at Department of Cardiac Surgery, Guangzhou Women and Children′s Medical Center, Guangzhou Medical University were reviewed retrospectively. There were 25 male and 15 female patients. The median age at AVV intervention was 4.5 to 204.0 months (M(Q_R): 42.5 (59.7) months), and the median body weight was 6.0 to 55.4 kg (M(Q_R): 13.8 (8.1) kg). The systemic AVV morphology included common AVV in 21 patients, mitral valve in 7 patients, tricuspid valve in 3 patients, and both mitral and tricuspid valve in 9 patients. At first surgical intervention, 15 patients had severe, 25 patients had moderate AVV regurgitation. The timings of the initial surgical intervention were at the first palliative, Glenn, between Glenn and Fontan, and Fontan stage in 5, 23, 4, and 8 patients, respectively. The methods of the initial surgical intervention were AVV repair in 31 patients, AVV replacement in 9 patients. Actuarial survivals were estimated by the Kaplan-Meier method. Prognosis factors for atrioventricular valve reoperation were analyzed using the Cox regression hazard model. Results: There were 6 early deaths, with a mortality of 15.0%. Thirty-four survival patients received a follow-up of 1 to 117 months (M(Q_R): 44 (34) months). Survival of patients after the initial surgical intervention were 85.0% (95% CI: 74.0% to 95.9%), 79.3% (95% CI: 66.6% to 92.0%), and 79.3% (95% CI: 66.6% to 92.0%) at 1 year, 5 years and 10 years, respectively. In all, only 13 patients completed the Fontan procedure. Six patients underwent 8 reoperations, including AVV replacement in 5 patients, redo AVV repair in 3 patients. Freedom from AVV reoperation at 1 and 5 years was 89.8% (95% CI: 78.8% to 100%) and 79.4% (95% CI: 64.7% to 94.1%), respectively. Multivariate Cox regression analysis revealed that common AVV (HR=3.53, 95% CI: 1.63-7.67, P=0.020) was the prognosis factors for AVV reoperation. Conclusions The early- and mid-term outcomes of surgical AVV intervention in FSV patients are not satisfactory. The mortality and reoperation rate are still high, and common AVV predicts the AVV reoperation after the initial surgical intervention.

Objective: To examine the early- and midterm outcomes of pulmonary artery banding as an initial palliation in patients with single ventricle associated with unrestricted pulmonary blood flow. Methods: Between January 2008 and December 2017, 49 patients with single ventricle and unrestricted pulmonary blood flow underwent pulmonary artery banding at Department of Cardiac Surgery, Guangzhou Women and Children′s Medical Center, Guangzhou Medical University. There were 29 males and 20 females. The age at the time of surgery was 5.6 (11.5) months (M(Q_R)), and the weight was 5.2 (3.9) kg. The medical records and results after pulmonary artery banding (death/reoperation, transition to the Glenn procedure) and subsequently after the Glenn procedure (death, transition to the Fontan procedure) were reviewed retrospectively. Actuarial survivals were estimated by the Kaplan-Meier curve. Relative factors for affecting outcomes were analyzed using the Cox regression hazard model. Results: There were 8 early deaths, with a mortality of 16.3%, including 4 cases who received simultaneous arch repair. There were 5 late deaths. During the follow-up of 47(62) (M(Q_R)) months, 11 patients (22.4%) underwent pulmonary artery banding adjustment, 29 patients (59.2%) underwent the Glenn procedure, 21 patients (42.8%) underwent the Fontan procedure. The survival of patients after the initial pulmonary artery banding were 77.4% (95%CI: 65.6% to 89.2%) and 72.6% (95%CI: 59.9% to 85.3%) at 1 year and 5 years, respectively. Multivariate Cox regression analysis revealed that systemic ventricular outflow tract obstruction (HR=4.25, 95%CI: 1.50 to 12.03, P=0.006) and total anomalous pulmonary venous connection (HR=6.49, 95%CI: 3.24 to 12.98, P=0.000) were relative factors for death. Conclusions The early and midterm outcomes of pulmonary artery banding as an initial palliative strategy is not satisfactory. Systemic ventricular outflow tract obstruction and total anomalous pulmonary venous connection are associated with high mortality.

Objective To review the early-and mid-term results of anatomic repair or Fontan pathway for congenitally corrected transposition of the great arteries(ccTGA) in a single institution of China.Methods Hospital records over a 9-year period(2009-2017) were reviewed to identify patients with ccTGA who underwent anatomic repair or Fontan pathway.Pa-tient-and procedure-related variables were reviewed.Results We identified 37 patients.Group 1 consisted of 10 anatomic re-pairs, of which 4 required prior pulmonary artery banding.Median age at anatomic repair was 1.0 years( range: 0.3 -7.8 years).There was one early death, and one patients experienced ECMO support.The mean follow-up was(3.0 ±2.8)years (range:0.7-8.4 years).Five(55.5％) patients showed arrhythmias, and one required permanent pacemaker implantation during follow-up.Group 2(27 patients) underwent Fontan palliation, of which 23(85.2％) underwent prior bidirectional Glenn shunt.Median age at Fontan completion was 3.8years(range:2.2-14.3 years).there was one early death with a mor-tality of 3.7％.The mean follow-up was(2.8 ±1.6) years(range:0.8-8.2 years).There was 4(15.4％) cases of arrhyth-mias, but none required reintervention.The arrhythmias incidence in Fontan group was significantly lower than the anatomic re-pair group.The early-and mid-term survival rate were 90.0％ and 96.3％in the two groups.The difference was not statistical-ly significant(P=0.458).Conclusion Patients with ccTGA do well with both anatomic repair and the Fontan pathway in the medium term.Pulmonary artery banding can be used effectively for morphological left ventricular retraining , and extenuate tri-cuspid regurgitation.Excellent outcomes with reduced early complication and arrhythmias incidence can be achieved for this co-hort of patients when a strategy of avoiding complex anatomic repair in favor of the Fontan pathway is used .

Objective: To review current-era palliation outcomes of patients with heterotaxy and functional single ventricle in a single institution. Methods: The clinical data of 70 consecutive patients with heterotaxy undergoing multistage single ventricle palliation in Guangzhou Women and Children′s Medical Center from January 2008 to December 2017 were retrospectively reviewed, and the prognosis factors for mortality were analyzed. There were 53 male and 17 female patients.The median age was 13.3 months (range: 6 days to 150 months). Single ventricle multistage palliation included 1^st stage palliation surgery, 2^nd bidirectional Glenn shunt, and 3^rd stage modified Fontan.The Kaplan-Meier method was used to estimate the probability of survival. Multivariate analysis was performed by Cox regression model. Results: Sixty-two patients had right atrial isomerism while eight had left atrial isomerism. Eighteen patients (25.7%) required the first stage palliation. Fifty-five patients received the Glenn shunt, and the Fontan procedure was completed in 27 patients. Overall, mortality occurred in 17 patients (24.3%) including 9 after the first stage palliation, 6 after the Glenn shunt, and 2 following the Fontan procedure. Survival estimates for the entire cohort following surgery were 81% (95%CI: 72% to 90%), 74%(95%CI: 64% to 85%), and 74% (95%CI: 64% to 85%) at 1 year, 5 years and 10 years, respectively. Survival estimates following the first stage palliation were 56% (95%CI: 33% to 79%) and 49% (95%CI: 26% to 73%) at 1 year and 5 years, respectively. Multivariate Cox regression analysis revealed that total anomalous pulmonary venous connection (TAPVC) (HR=6.16, 95%CI: 1.65 to 22.95, P=0.007), atrioventricular valve regurgitation more than moderate (HR=3.81, 95%CI: 1.32 to 10.94, P=0.013) and required the first palliation surgery (HR=4.58, 95%CI: 1.34 to 15.72, P=0.016) were prognosis factors for overall mortality. Conclusions The management of heterotaxy patients with functional single ventricle remains challenging, and the outcomes are continously improving in china. TAPVC, atrioventricular valve regurgitation more than moderate and required the first palliation surgery still are prognosis factors for overall mortality in heterotaxy syndrome.

Objective: To investigate the indication, feasibility, and safety of da Vinci robotic surgical system in pharyngolaryngeal tumor resection. Methods: Thirty patients were diagnosed with pharyngolaryngeal tumors and treated with a transoral robotic surgery (TORS) in Beijing Anzhen Hospital from June 1, 2016 through November 30, 2017. Inclusion criteria included lesions of the oropharynx (n=13), parapharyngeal space (n=7), larynx (n=6) and hypopharynx (n=4). Twenty cases were males and ten cases were females. The median age was 56 years old (ranging from 30 to 81 years). Results: The robotic surgeries were performed successfully on 30 patients. One patient (3.3%) underwent TORS combined with a neck incision. The mean operative time was 40.7 min. The mean blood loss was 15.8 ml. The mean recovery time for oral intake was 5.3 days. The mean hospital stay was 9 days. None of the patients underwent tracheotomy or mandible split. Postoperative pathological examination showed that 18 cases (60.0%) were malignant and 1 case (5.6%) had positive surgical margin. Sixteen cases received neck dissection. No serious complications occurred during or after the operation. There was no local recurrence, metastasis or death except for regional recurrences in 2 cases (11.1%) with a follow-up of 1 to 18 months(median 13 months). Conclusion Transoral robotic surgery is a feasible, safe and effective surgical procedure with clear operation field, rapid surgical access, minimally invasive surgery, lesser hemorrhage, good cosmetic effect and fast recovery.
