Objective To investigate the therapeutic efficacy of minimally invasive modified transforaminal lumbar interbody fusion (TLIF) combined with unilateral nail holding system in patients with extreme lateral lumbar disc herniation.Methods Thirty-eight patients with extreme lateral lumbar disc herniation were divided into minimally invasive modified TLIF combined with unilateral nail holding system group (observation group) and conventional open TLIF group (control group) with 19 cases each according to random digital table method.The therapeutic efficacy was compared between 2 groups.Results Surgery was completed successfully in 2 groups,and there was no perioperative complications.The amount of bleeding and hospital stay length in observation group were significantly less than those in control group:(152 ± 82) ml vs.(258 ± 104) ml and (6.5 ± 2.3) d vs.(12.7 ± 3.6) d,and the rate of fusion and score of Japan Orthopaedic Association 6 months after surgery in observation group were significantly higher than those in control group:18/19 vs.10/19 and (14.5 ± 2.1) scores vs.(12.6 ± 1.9) scores.There were statistical differences (P ＜ 0.01).There was no statistical difference in complications between 2 groups (P ＞ 0.05).Conclusion Minimally invasive modified TLIF combined with unilateral nail holding system in patients with extreme lateral lumbar disc herniation has less blood loss and shorter hospital stay,and it is effective and safe.

Objective To evaluate the left ventricular systolic dyssynchrony in patients with left ventricular apical ballooning syndrome (LVABS) quantitatively by real-time three-dimensional echocardiography(RT-3DE) and its correlation with left ventricular ejection fraction(LVEF).Methods 7patients with LVABS were enrolled in this study.The images of left ventricle in full volume mode were obtained by RT-3DE in the different time (just after admission,4 weeks and 8 weeks).Post-processing software of 4D LV Volume Tom-Tec was used for calculation of EF and 16-segmental time-volume curves was obtained.The time to the point with minimal systolic volume(Tmsv) of each segment was calculated and by which the following indexes of systolic dyssynchrony were derived:Tmsv16-SD/Dif,Tmsv-basalSD/Dif,Tmsv-mid-SD/Dif and Tmsv-apical-SD/Dif.The correlation between systolic dyssynchrony index (SDI) and LVEF was analysed.Results ① The Tmsv16-SD/Dif,Tmsv-basal-SD/Dif,Tmsv-mid-SD/Dif and Tmsv apical-SD/Dif of left ventricle in the patients of 4 weeks and 8 weeks were smaller than those of the patients just after admission.There were significant differences among them(all P ＜0.05).②The more SDI increased,the more LVEF decreased,and vice versa.SDI was negatively associated with LVEF in the different time of admission (just after admission:r =-0.758; 4 weeks:r =-0.831 ; 8 weeks:r =-0.889;all P ＜0.05).Conclusions Left ventricular systolic dyssynchrony of severe degree is observed in patients with LVABS just after admission.But the condition of dyssynchrony has been improved gradually after 4 weeks and 8 weeks.SDI is negatively correlated with LVEF.

Objective:To explore the clinical efficacy of dual-kidney transplantation from infant donors to adult recipients.Methods:From December 2012 to November 2020 in Organ Transplant Center First Affiliated Hospital Sun Yat-sen University, rertrospective reviews were conducted for clinical data of 25 pairs of infant donors and adult recipients. The survival rates were calculated for both recipients and transplanted kidneys at Year 1/3/5 post-transplantation. And the postoperative recovery status and the postoperative incidence of adverse events of recipients were observed.Results:The survival rates of recipients were all 95.8% at Year 1/3/5 and those of transplanted kidney and dealth-cancelling transplanted kidney all 87.2%. One case died due to acute inferior-wall cardiac infarction while three others lost renal functions for vascular thrombosis, ureteral stenosis and urinary fistula. Except for loss of renal function and death, the postoperative estimated golmerular fitration rate was (99.35±21.78), (103.11±29.20) and (114.99±28.55) ml/(min·1.73 m 2) at Year 1/2/3 respectively. Conclusions:Selecting proper recipients, standardizing donor acquisition and surgical procedures and strengthening perioperative managements may expand the donor pool. The overall outcomes are excellent for adult recipients with dual-kidney transplantation from donations after infants' death.

Intramesorectal lymph node metastasis after radical surgery of prostate cancer is rare in clinical practice. This paper reported 2 cases of intramesorectal lymph node metastasis and resection after operation for prostate cancer. Patient 1 underwent laparoscopic radical prostatectomy 5 years ago, who was followed up closely after surgery, and was diagnosed with mesorectal lymph node metastasis by MRI examination. Patient 2 underwent robot-assisted laparoscopic radical prostatectomy 2 months ago, who was followed up by pelvic MRI and mesorectal lymph node metastasis was revealed. Both patients underwent fluorescence laparoscopic mesenteric lymphadenectomy in our department. With 4 to 6 month of follow-up after surgery, MRI examination showed no recurrence of tumor.

Objective To explore the clinical outcome of renal transplantation and analyze the risk factors influencing the kidney allograft survival after transplantation.Methods The clinical data of 524 cases of renal transplantation between January 2007 and December 2015 were retrospectively analyzed.Serum creatinine was determined,and glomerular filtration rate(GFR) was estimated.The 1-,2-and 3-year patient and graft survival after transplantation was calculated.Adverse events were recorded.Results The median follow-up time was 17.2 months.The 1-,2-and 3-year graft survival rate after transplantation was 97％,95.8％ and 95.3％,respectively.The 1-,2-and 3-year patient survival rate after transplantation was 97.8％,97％ and 97％,respectively.The eGFR was (67.6 ± 24.1),(68.9±24.2) and (72.7 ± 26.2) ml·min-1 ·1.73 m-2 at 1st,2nd and 3rd year after transplantation.The incidence of delayed graft function(DGF) was 20.6％ (108/524).Multivariate analysis revealed donor type (P =0.005) and the terminal creatinine (P＜0.001) were the independent risk factors of DGF.Elder recipients (P =0.004),recipients with diabetes(P =0.031),preoperative positivity of panel reactive antibody(PRA) (P =0.023),and donor with hypertension (P =0.046) were risk factors influencing the kidney allograft survival.Conclusion Kidney transplantation showed good outcomes at 3rd year after transplantation.The recipient age,recipient's history of diabetes,preoperative PRA and donor's history of hypertension are independent risk factors for renal graft survival.

Objective To analyze the 10-year survival outcome and failure patterns for patients with nasopharyngeal carcinoma (NPC) after intensity-modulated radiotherapy (IMRT),aiming to provide reference for optimized treatment for NPC.Methods Clinical data of 866 patients with NPC receiving IMRT from January 2001 to December 2008 were retrospectively analyzed.Survival analysis was performed using the Kaplan-Meier estimator.Univariate analysis was carried out by log-rank test and multivariate analysis was performed using Cox proportional hazards model.Results The median follow-up time was 132 months.The 10-year local recurrence-free survival (LRFS),distant metastasis-free survival (DMFS),progression-free survival (PFS) and disease specific survival (DSS) were 92.0％,83.4％,75.7％ and 78.6％,respectively.A total of 210 patients died including 124 patients (59.0％) from distant metastasis,which was the primary cause of death,and 47 (22.3％) from local regional recurrence.Independent negative factors of DSS included age＞50 years (P=0.00),LDH ≥ 245 IU/L (P=0.00),Hb＜ 120 g/L (P=0.01),T2-T4 staging (P=0.00),N1-N3 staging (P=0.00) and GTV-nx＞20 cm3(P=0.00).The 10-year LRFS,DMFS and DSS of stage Ⅱ NPC patients did not significantly differ after IMRT alone and chemoradiotherapy (P=0.83,0.22,0.23).For patients with stage Ⅲ NPC,the 10-year LRFS and DSS in the chemoradiotherapy arm were significantly higher than those in the IMRT alone (P=0.01,0.01),whereas no statistical significance was observed in the DMFS between two groups (P=0.14).The overall survival of stage Ⅳa+Ⅳb NPC patients is relatively poor.Conclusions IMRT can improve the long-term survival of NPC patients.Distant metastasis is the primary failure pattern.Patients with stage Ⅰ-Ⅱ NPC can obtain satisfactory survival outcomes after IMRT alone.The addition of chemotherapy can further enhance the LRFS and DSS of stage Ⅲ NPC patients.However,the optimal therapeutic strategy remains to be urgently investigated for stage a+ Ⅳb NPC patients.

Objective:To evaluate the effectiveness and safety of ultrasound-guided hydrostatic reduction for pediatric acute intussusception.Methods:One thousand eight hundred and thirty patients with acute intussusception diagnosed by ultrasound in Shenzhen Children′s Hospital from September 2017 to July 2020 were treated with ultrasound-guided hydrostatic reduction method. The therapeutic effects, complications and ultrasonic features were observed.Results:Among 1 830 cases, 1 791 cases were diagnosed as primary intussusception, and 39 cases were secondary intussusception. The overall rate of successful ultrasound enema reduction were 1 780/1 830(93.7%) patients. All 50/1 830(2.7%) patients underwent surgery after unsuccessful enema reduction, including 42 cases of primary intussusception, and 8 cases of secondary intussusception. The complication of intestinal perforation occurred in 3 cases (0.16%), and there were no deaths.Conclusions:Ultrasound-guided enema reduction for pediatric acute intussusception is an effective and safe method without radiation exposure, and can be used as the preferred method for non-operative treatment of intussusception.
