Objective Based on the disadvantages of NUSS procedure, we design a new type of funnel chest orthodontic steel bars for clinical application to simplify surgery operation , reduce the surgical trauma, improve operation effect, enhance the safety of operation, and relieve the suffering of the patients, etc.Methods From June 2010 to July 2015, 1020 patients used the new type of funnel chest orthodontic metal plates, including 706 cases of males and 314 cases of females, aged 3-40(aver-age age 11.38 ±5.31).Haller index of 3.36 to 15.45(average index 4.97 ±1.58).668 symmetrical funnel chest cases, 281 cases of asymmetry and 71 recurrent funnel chest cases are involved.Surgical steel bars, having 15 specifications, are arc-shaped, the lengths of which are from 12cm to 26cm.The two ends of steel bars have fixed piece, one end of the bar was fused with a stabilizer and the other end connected to an introducer or a stabilizer and use screws to fix two ends .Steel plates, as the design product, are finalized in the factory.Therefore we need not make intraoperative reprocess.Front tip of introducer and the back-end can be connected to the metal plate.Patients were placed supine position under general anesthesia.Two inci-sions, with length about 2cm and deep to the rib periosteum were made along axillary midline line on the both sides .In the di-rection of high blunt slightly medial free for subcutaneous tunnel to the highest point .Fixed wires were worn around the ribs on both sides.A thoracoscope to guide the bar was inserted from the highest point on the right side of the rear of the medial by sternum low into the chest from the left corresponds to the highest point of the medial , remove the introducer to connect another stator, use screws to fix the connection, with a fixed stator and steel plate stabilized.At the end of the surgery, the stabilizer on either side was secured with sutures.Results The median first operation time was 23 -45(32.31 ±3.57)min, second op-eration time was about 34-147(68.27 ±30.25)min..The bleeding volume(first operation) was 0-2(0.40 ±0.36)ml, the bleeding of second operation time was 1-630(144.00 ±57.00)ml.The hospital stay was 3-9(4.22 ±0.61)days after the operation.All the cases were followed up for 34-48(34.4 ±6.1)months.Steel plate was fixed at the bottom of the sternum in 957 of them,with slight shifting in 58 patients.There was another 5 cases who need re-operation because of the obvious shift-ing.Conclusion The new type of funnel chest orthodontic steel bars simplify surgery operation, reduce the surgical trauma, improve operation effect, relieve the suffering of the patients and enhance the safety of operation.

Objective To summarize the experience of patient positing,port placements setting and robot cart docking in pediatric robot-assisted laparoscopic upper urinary tract operations.Methods From March 2017 to December 2017,140 robot-assisted laparoscopic upper urinary tract procedures were performed in our institution,including 110 cases of pyeloplasty,15 upper pole heminephroureterectomy,12 simple nephrectomy and 3 adrenalectomy.There were 103 males and 37 females with a range age from 1 month to 18 years.The assistant surgeon was adjacent to the instrument nurse,and patients were placed in a supine position with 60°-80° inclination and keep the legs low to the body.Room setup and patient positioning were similar to the traditional laparoscopic surgery.Semi-hidden incision technique was used in 140 patients:the camera port was placed umbilicus,two additional arm ports (one 5 mm and one 8 mm) were placed under direct vision,the 8 mm arm port was placed on the line of a Pfannenstiel incision and the 5 mm arm port was placed below the Xiphoid along the midline.Finally,a 3 or 5 mm assistant port was placed approximately 3 cm lateral to the inferior arm port,the line of a Pfannenstiel incision.Results The average time was (11.5 ± 3.2) min (10.5-16.5 min) from skin incision to robot cart docking completed.All surgeries were successfully completed without open conversion.One patient required an additional assist port for severe adhesion after the previously open surgery,there was no injury to other viscera.Average operative time was (146.9 ± 48.7)min (78-259 min) and average post-operative hospitalization time was (5.7 ± 1.4) d(4-10 d),respectively.There was no visual scar on abdominal 6 weeks postoperatively,and all parents made comments about their satisfaction with the cosmetic appearance.All operations got complete success at a mean follow up of 6 (1-9) months.Conclusions A good room setup,patient positioning and the semi-hidden incision technique port placements are maintaining the safety of the patient,avoiding compression injuries,allowing maximum mobility of the robotic arms,and facilitating a smooth and efficient surgery,and improving post-operative recovery.

Objective:To analyze the hot topics and trends in the field of humanistic education in pediatrics in China, and to provide a reference for the development and research of pediatric humanistic education.Methods:Relevant literature was retrieved throughout the China National Knowledge Infrastructure between database establishment and September 20, 2023, using fuzzy matching and key information. CiteSpace 6.1.6 software was used to perform a visual analysis of the year of publication, core authors, issuing institutions, and research themes.Results:A total of 284 pieces of literature were included. Research in the field of pediatric humanistic education is at the second stage of scientific literature growth. There are 8 high-frequency authors (2.14%), contributing a total of 25 articles (8.80%). The majority of articles were issued by hospitals. Humanistic care in pediatric nursing practice is one of the earliest and ongoing major research topics. Themes such as "doctor-patient communication", "humanistic literacy", and "humanistic nursing" are attracting growing attention.Conclusions:In the field of pediatric humanistic education, core groups of authors and institutions have not yet formed, and collaboration between authors and institutions is insufficient. Research hotspots in pediatric humanistic education are changing over time. Strengthening interdisciplinary and interinstitutional collaborations can help build core research teams, produce more research output, and thereby promote the development of pediatric humanistic education in China.

Objective    To explore the feasibility and efficacy in therapy of pectus excavatum using novel modified Nuss procedure after congenital heart disease (CHD) operation. Methods    Thirty-six children (including 22 males and 14 females with an average age of 4.5±2.2 years ranging 2.8-18.0 years) with pectus excavatum after CHD operation from January 2011 to March 2015 were selected as an observation group. Thirty-eight pectus excavatum children (including 24 males and 14 females with an average age of 4.0±2.5 years ranging 2.8-20.0 years) without CHD from July to September 2013 were selected as a control group. The novel modified Nuss procedure was performed on the patients in both groups. The operation time, intraoperative blood loss, hospital stay as well as postoperative complications between two groups were reviewed and analyzed. Results    In the observation group, the operation time was 50-72 (60.50±3.60) min and hospital stay was 4-6 (4.41±0.80) d. Meanwhile, the intraoperative blood loss was 5-10 (5.82±0.35) ml. In the control group, the operation time was 12-45 (20.15±0.68) min, hospital stay was 4-7 (4.61±0.63) d and the intraoperative blood loss was 3-8 (4.62±0.28) ml. The operation time was significantly longer in the observation group than that in the control group (P<0.05). But there was no significant difference in intraoperative blood loss or hospital stay between the two groups (P>0.05). No cardiac rupture happened in the two groups. Conclusion    The novel modified Nuss procedure is safe and feasible for pectus excavatum after CHD operation with optimal outcomes.
