Objective: To investigate the clinical outcomes of selective major aortopulmonary collaterals(MAPCAs) unifocalization and report histopathological findings in patients with pulmonary atresia with ventricular septal defect and major aortopulmonary collaterals(PA/VSD/ MAPCAs). Methods: The study enrolled 6 MAPCAs/VSD/PA patients with age ranged from 6 to 96 months and body weight ranged from 5.0 to 23.0 kg. These patients underwent selective MAPCAs unifocalization and primary repairs. Preoperative cardiac catheter, selective arteriography, cardiac CTA and intraoperative pathology were performed to identify different function, anatomic distribution and histopathology of MAPCAs. Results: 6 MAPCAs/VSD/PA patients underwent selective MAPCAs unifocalization and primary repair. No death occurred after operation and at follow-up which lasted for 1 to 20 months. Preoperative cardiac catheter, selective arteriography and intraoperative histopathology demonstrated distribution of functional MAPCAs similar to native pulmonary artery arborization and participating in arterial gas exchange. Functional MAPCAs were classified into elastic arteries according to histopathology. Conclusion There are two histological type of MAPCAs which play different roles. Selective unifocalization to functional MAPCAs which are classified into elastic arteries like native pulmonary artery is a safe and effective treatment approach for PA/VSD/MAPCAs.

Objective To investigate the clinical performance of ultrasound screening for fetal structural anomalies at 11-13+6 weeks of gestation and to evaluate the relation of structural anomalies with karyotypes and copy number variations. Methods A retrospective analysis was conducted on fetuses with structural anomalies detected by ultrasound examination at 11-13+6 gestational weeks in First Affiliated Hospital of Sun Yat-Sen University from January 2013 to December 2017. Karyotype and chromosomal microarray analysis(CMA) were offered to these fetuses and ultrasound scans were repeated at 16-18 gestational weeks. All fetuses were followed up to termination or birth. Fisher's exact test was used for statistical analysis. Results A total of 362 fetuses with structural anomalies were studied including 101 (27.9%) fatal malformations, 253 (69.9%) major malformations and eight (0.2%) minor malformations. Cardiac malformation (32.6%, 118/362), central nervous system anomalies (24.9%, 90/362) and anterior abdominal wall defects (20.9%, 76/362) were the three most common abnormalities. Invasive prenatal test was performed in 107 cases including 25 fatal, 79 major and three minor malformations. Thirty (28%) out of the 107 cases had abnormal karyotypes, which were chromosomal aneuploidies (n=28) and chromosomal fragment abnormalities (n=2). Among the 99 cases received CMA, 25 had abnormal karyotypes, and copy number variations were identified in eight [three (4.05%) were pathogenic variations] out of the rest 74 with normal karyotypes. The incidence of chromosomal abnormalities in fetuses with major malformations was higher than that of fetuses with fatal malformation [32.9% (26/79) vs 12.0% (3/25), P=0.045]. Altogether, 117 cases repeated second-trimester ultrasound among which 16 (13.7%) were normal; 19 (16.2%) had cardiac defect which was discordant with the first-trimester evaluation and five (4.2%) were found to have additional malformations. Diagnosis of the other 77 cases were consistent with the first-trimester ultrasound findings. After the second-trimester ultrasound scanning, 49 pregnancies were terminated; 39 twin pregnancies and four triplet pregnancies underwent selective fetal reduction; 25 continued to delivery with good neonatal outcomes. Out of the 23 699 cases without abnormal ultrasound findings at 11-13+6 gestational weeks, 20 182 (85.2%) were successfully followed up, among which structural abnormalities were found in 178 during the second trimester and in 31 after birth. Conclusions A detailed ultrasound examination at 11-13+6 weeks of gestation is important to identify fetal structural defects. However, it could not replace the second-trimester ultrasound. There is a high risk of chromosomal abnormalities in fetuses with early-detected structural defects. CMA is able to identify pathogenic copy number variations with a relatively low detection rate.

Objective: To discuss the application principle in tuina manipulation for lumbar intervertebral disc herniation (LIDH) in Chinese literatures published in recent 30 years. Methods: The three major Chinese databases, Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP) and China National Knowledge Infrastructure (CNKI), were searched to collect the studies of tuina manipulations in treatment of LIDH published in recent 30 years. Clustering analysis was applied to analyze the top 20 tuina manipulations for LIDH. Results: The top 20 most frequently used manipulations for LIDH were Gun-rolling, Rou-kneading, Dian-digital pressing, oblique Ban-pulling, An-pressing, Tanbo-plucking, Bashen-pulling and extending, horizontal Tui-pushing, Na-grasping, Anrou-pressing and kneading, Dou-shaking, Yao-rocking, Ca-scrubbing, Pai-patting, post-extension Ban-pulling, Mo-rubbing, Zhen-vibrating, Nie-pinching, fist-back Ji-tapping, and dorsal Shen-extending methods. The involved manipulations can be divided into two categories by the treated body areas. One category is applied to the soft tissues, including Gun-rolling, Rou-kneading, Dian-digital pressing, An-pressing, Tanbo-plucking, horizontal Tui-pushing, Na-grasping, Anrou-pressing and kneading, Ca-scrubbing, Pai-patting, Mo-rubbing, Zhen-vibrating, Nie-pinching, and fist-back Ji-tapping methods. The other category is applied to bones and joints, including oblique Ban-pulling, Bashen-pulling and extending, Dou-shaking, Yao-rocking, post-extension Ban-pulling, and dorsal Shen-extending methods. Conclusion: Based on the treated body area, the tuina manipulations applied to treat LIDH are predominated by the ones performed on soft tissues, assisted by those on bones and joints. From the way of force exertion, the involved manipulations are majorly the swinging methods, followed by squeezing and pressing ones. The manipulations applied to bones and joints are predominated by the Ban-pulling ones, followed by the Bashen-pulling and extending ones.

Objective To observe the effect of different dosage combinations of nalbuphine and sufentanil on postoperative analgesia in patients undergoing abdominal hysterectomy surgeries. Methods One hundred and twenty-five patients scheduled for selective abdominal hysterectomy surgeries in Affiliated Huaian Hospital of Xuzhou Medical University from January 2015 to January 2018 were randomly divided into sufentanil 100 μg group (group S), sufentanil 75 μg combined with nalbuphine 25 mg group (group NS1), sufentanil 50 μg combined with nalbuphine 50 mg group (group NS2), sufentanil 25 μg combined with nalbuphine 75 mg group (group NS2) and nalbuphine 100 mg group (group N). The analgesic pump was set in the five groups as follows: loading dose 3 ml, continuous dose 2 ml/h, bolus dose 0.5 ml, lockout time 15 min, total volume 100 ml. The scores of incision pain and visceral pain of 4, 8, 12, 24 and 36 h of NRS, Ramasy sedation score, number of analgesia pump compressions and incidence of adverse reactions were recorded respectively in patients after operation. Results Compared with those in group NS3 and group N,the scores of incision pain of NRS were significantly lower 4 and 8 h after surgery in group S, group NS1 and group NS2 (P < 0.05). Compared with those in group S and group NS1, the scores of visceral pain of NRS was significantly lower at the time 4 and 8 h after surgery in group NS2, group NS3 and group N (P<0.05). Compared with group NS2, the number of analgesia pump compression was significantly higher in group S, group NS1, group NS3 and group N, (3.0 ± 1.7), (3.0 ± 1.5), (2.9 ± 1.8), (2.9 ± 1.6) times vs. (1.7 ± 1.0) times, P<0.05. Compared with those in group S, the nausea and vomiting were lower in group NS2,group NS3 and group N, nausea: 8%(2/25), 8%(2/25), 4% (1/25) vs. 20% (5/25), vomiting: 8% (2/25), 8% (2/25), 8% (2/25) vs. 20% (5/25), P < 0.05. Conclusions The optimal ratio of nalbuphine to sufentanil in postoperative analgesia after abdominal hysterectomy surgeries was 1∶1, because it has good analgesic effect and low incidence of adverse reactions.

Vacuum sealing drainage (VSD) is frequently used in abdominal surgeries. However, relevant guidelines are rare. Chinese Trauma Surgeon Association organized a committee composed of 28 experts across China in July 2017, aiming to provide an evidence-based recommendation for the application of VSD in abdominal surgeries. Eleven questions regarding the use of VSD in abdominal surgeries were addressed: (1) which type of materials should be respectively chosen for the intraperitoneal cavity, retroperitoneal cavity and superficial incisions? (2) Can VSD be preventively used for a high-risk abdominal incision with primary suture? (3) Can VSD be used in severely contaminated/infected abdominal surgical sites? (4) Can VSD be used for temporary abdominal cavity closure under some special conditions such as severe abdominal trauma, infection, liver transplantation and intra-abdominal volume increment in abdominal compartment syndrome? (5) Can VSD be used in abdominal organ inflammation, injury, or postoperative drainage? (6) Can VSD be used in the treatment of intestinal fistula and pancreatic fistula? (7) Can VSD be used in the treatment of intra-abdominal and extra-peritoneal abscess? (8) Can VSD be used in the treatment of abdominal wall wounds, wound cavity, and defects? (9) Does VSD increase the risk of bleeding? (10) Does VSD increase the risk of intestinal wall injury? (11) Does VSD increase the risk of peritoneal adhesion? Focusing on these questions, evidence-based recommendations were given accordingly. VSD was strongly recommended regarding the questions 2-4. Weak recommendations were made regarding questions 1 and 5-11. Proper use of VSD in abdominal surgeries can lower the risk of infection in abdominal incisions with primary suture, treat severely contaminated/infected surgical sites and facilitate temporary abdominal cavity closure.

OBJECTIVE: To clone the promoter sequence of acute monocytic leukemia new antigen gene.MLAA-34 and identify its promoter core region. METHODS: The full-length fragment of MLAA-34 gene promoter region was amplified by PCR, then was ligated into pGL3-Basic vector, and the recombinant plasmid was cloned. Constructed a series of MLAA-34 gene promoter 5' flanking region truncated plasmid. These recombinant plasmids were transfected into U937 and HEK293 cells, and the dual luciferase reporter gene was used to detect the promoter activity of each fragment to determine the minimum active region. Transcription factor binding sites were analyzed by bioinformatics methods. RESULTS: The recombinant plasmid containing MLAA-34 promoter sequence and its truncated plasmid were successfully constructed, and the promoter activity was significantly increased as compared with the empty vector (P＜0.001). The minimal active region of MLAA-34 located between 402 bp and 200 bp. It contained multiple transcription factor binding sites such as E2F1, MZF-1, SP1, USF2 and STAT3. CONCLUSION The promoter of luciferase reporter gene has been successfully constructed with different deletion fragments of MLAA-34, and its core promoter region may contain multiple transcription factor sequence.
