Objective:To investigate the therapeutic effect of modified Zhuyujingkang decoction combined with glucosamine sulfate on cervical spondylosis and its influence on the serum level of thromboxane B2(TBX 2). Methods:From June 2017 to June 2019, 82 patients with cervical spondylosis in the Maternal and Child Health Hospital of Zhoushan were selected, and they were divided into control group and observation group according to the random digital table method, with 41 cases in each group.The control group was treated with glucosamine sulfate, and the observation group was treated with modified Zhuyujingkang decoction on the basis of the control group.The course of treatment in both two groups was 4 weeks.The therapeutic effects of the two groups were compared.The changes of VAS, NDI and TBX 2 before and after treatment were compared. Results:The total effective rate of the observation group was 92.68%, which was higher than 70.73% of the control group(χ 2=6.609, P<0.05). After treatment, the VAS score of the observation group was (3.82±0.42)points, which was lower than (4.52±0.38)points of the control group( t=8.479, P<0.05). The NDI score of the observation group was (22.31±2.68)points, which was lower than (27.39±1.89)points of the control group( t=9.919, P<0.05). The serum level of TBX 2 in the observation group was (57.84±3.19)ng/L, which was lower than (65.74±2.48)ng/L in the control group( t=12.519, P<0.05). Conclusion:The therapeutic effect of modified Zhuyujingkang decoction combined with glucosamine sulfate on cervical spondylosis is good.It can reduce the pain, improve the related function of neck and shoulder, and reduce the level of TBX 2, which is worthy of clinical reference.

Objective:To evaluate the effectiveness of integrated pediatric training course of extracorporeal membrane oxygenation(ECMO)based on simulation teaching.Methods:The instructors of ECMO team of Children′s Hospital of Fudan University developed the teaching curriculum.Team members as a unit were recruited to study simulation-based courses, whose theoretical knowledge, skills and teamwork were assessed, and feedback from the trainees were gathered.Results:Since May 2018, 22 teams of pediatric specialized hospitals or general hospitals have taken part in our ECMO simulation, with totally 132 participants, including 45 ICU doctors(34.1%), 60 ICU nurses(45.5%), 23 thoracic surgeons(17.4%) and four anesthesiologists(3.0%). Twelve of them(9.1%)had a little ECMO experience.After training, the trainees had a high evaluation on each part of the course, with average score more than four, of which the theoretical score was lowest.Their self-evaluation on the theory, skills, teamwork and confidence in the implementation of ECMO had been significantly improved.Most(80.3%)of the trainees were confident to carry out ECMO in their local hospitals.The trainees′ baseline score of theoretical knowledge was 55.2±7.6, and increased to 67.1±7.3 after training( P<0.001). The average teamwork score of the 22 teams was 70.2±8.2, and the qualified rate was up to 86.4%.The most prominent skill problems in operation assessment were no albumin and blood priming(90.9%), non-skill problems were extremely anxious during the overall assessment(84.8%)of the participants, poor team work(74.2%), poor leadership(68.2%). For the feedback of the whole course, 97.0% and 94.7% of the trainees thought that integrated training and simulation teaching were the highlights of the course.At present, 13(59.1%)units have successfully developed ECMO technology after the course, and the number of children treated has been up to 83, with a survival rate of discharge of 54.2%.However, it was found that the skill level of some participants decreased about 2 weeks after the course. Conclusion:As a new attempt of ECMO teaching, this curriculum has achieved certain efficiency in both teaching and clinical practice.At the same time, our study also plays a role in promoting the development of ECMO in pediatrics.

Objective To discuss the necessity of closing the peritoneum during the operation of ileal conduit after the radical cystectomy.Methods We retrospectively analyzed the clinical data of 395 patients with bladder cancer who received radical cystectomy from Jan.2014 to Sep.2016.The amount of male was 327,female was 68.The mean age was (65.8 ± 9.7) years old.Patients were divided into four groups according to the surgical method of cystectomy and urinary diversion.In group A,patients,including 78 males and 9 females,were received open radical cysectomy (ORC) with extraperitoneal ileal conduit.The mean age was (67.8 ± 9.2) years old.In the preoperative clinical staging,66 cases were less than T2 and 21 cases were more than T2.Preoperative pathological grade in 83 cases and low grade in 4 cases.In group B,patients,including 31 males and 2 females,were accepted ORC with ileal conduit without peritoneum closure.The mean age was (67.3 ± 8.7) years old.Preoperative clinical staging showed less than T2 in 25 cases,more than T2 in 8 cases,The preoperative pathological grade showed high grade in 33 cases.In group C,patients,including 112 males and 27 females,were accpeted LRC with ileal conduit without peritoneum closure.The mean age was (64.3 ± 10.5)years old.The preoperative clinical staging showed less than T2 in 107 cases and more than T2 in 32 cases.The preoperative pathological grade showed high grade in 135 cases and low grade in 4 cases.In group D,patients,including 106 males and 30 females,were accepted RARC with ileal conduit without peritoneum closure.The mean age was (65.9 ±10.0)years old.Preoperative clinical staging showed less than T2 in 103 cases and more than T2 in 33 cases.The preoperative pathological grade showed high grade in 132 cases and low grade in 4 cases.Ileal conduit without peritoneum closure means completely open the peritoneum after anastomosis of the ureter and intestine in the urinary diversion surgery without shutting down the peritoneum,which is different from the extraperitoneal ileal conduit.The operating time,blood loss,blood transfusion rate,recovery time of intestinal function and perioperative complications and rate of hydronephrosis were analyzed.Results The 395 cases completed operation successfully,no LRC or RARC had been converted to ORC.The operative time was (280.1 ± 92.3) min,(233.6 ± 99.4) min,(304.8 ± 108.9) min,(364.6 ± 86.4) min in four groups,respectively (P ＜ 0.05).The blood loss in four groups were (489.1 ± 285.6) ml,(431.8 ± 233.1) ml,(373.0 ±213.7) ml,(205.6 ± 137.8) ml,respectively (P ＜0.05).The transfusion rate in four groups were 18 (20.7％),16 (48.0％),15 (10.8％),14 (10.3％),respectively (P ＜ 0.05).The mean time to flatus in four groups were (3.7 ±1.8)d,(3.6±1.0)d,(3.5±1.2)d,(2.2±1.7)d,respectively (P ＜ 0.05).While ileal obstruction rate had no statistical difference in four groups [group A 17 cases(19.5％),group B 6 cases(18.2％),group C 27 cases(19.4％),group D 19 cases(14.0％),P =0.678].Urine leakage,intestinal leakage,lymphocyst were only occurred in group A [7 cases (8.0％),2 cases (2.3％),2 cases (2.3％)].Pyelonephritis was noticed in each group,including 14 cases(16.1％)in group A,2 cases(6.1％)in group B,9 cases (6.5％)in group C,6 cases(4.4％)in group D (P ＜ 0.05).Hydronephrosis 6 months after surgery was observed in four groups,including 15 cases(17.2％)in group A,3 cases(9.1％)in group B,7 cases(5.0％)in group C,5 cases(3.7％)in group D (P ＜ 0.05).Conclusions Ileal conduit without peritoneum closure would not increase the incidence of complications,on the contrary,it would relieve the tension of anastomosis,and reduce the occurrence of complications such as urine leakage.

Objective To investigate the therapeutic effect of post-traumatic complex posterior urethral stricture in the male patients.Methods Clinical data of 479 male patients with post-traumatic complex posterior urethral stricture were reviewed.One-stage resection of the stenosis and end-to-end anastomosis was performed in 422 patients and scrotal flap with blood pedicle posterior urethroplasty in 57.Results The mean operation time was 115 minutes(range,90-140 minutes).The mean blood loss was 225 ml(range,100-300 ml).No intraoperative blood transfusion was needed.The mean follow-up time was 15 months(range,12-24 months).Among the 422 patients performed end-to-end anastomosis,386 patients had good voiding and 36 had dysuria because of the formation of anastomotic stoma valve(21 patients)or stricture ring(15 patients).The problem was resolved by transurethral valve/stricture ring resection.Among 57 patients undergone posterior urethroplasty,45 patients had good voiding nine patients were found with anterior urethra-skin tube anastomotic stoma stricture,of which four patients were treated by urethral dilatation and five by endourethrotomy; three patients were found with posterior urethra-skin tube anastomotic stoma stricture,of which one patient was treated by urethral dilation and two by endourethrotomy.Conclusions One-stage resection of the stenosis and end-to-end anastomosis is the main treatment for post-traumatic complex posterior urethral stricture.If the condition of the patients does not allow the end-to-end anastomosis,posterior urethroplasty can be an alternative.
