Objective:To explore the clinical phenotype and genetic etiology for a Chinese pedigree affected with Autosomal dominant polycystic kidney disease (ADPKD).Methods:A pedigree with ADPKD diagnosed at the Department of Gynaecology of the First Affiliated Hospital of Zhengzhou University in December 2020 was selected as the study subject. Clinical data of the pedigree was collected, and whole exome sequencing (WES) was carried out for the proband. Candidate variants were verified by Sanger sequencing of the proband and her relatives. This study was approved by the First Affiliated Hospital of Zhengzhou University (Ethics No. KS-2018-KY-36).Results:Fetal ultrasonography showed increased volume and parenchymal echogenicity in both kidneys. The fetus was found to harbor c. 11098C>T (p.R3700C) and c.11039T>C (p.F3680S) compound heterozygous variants of the PKD1 gene, which were respectively inherited from its mother and father. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), both variants were predicted to be likely pathogenic (PM1+ PM2_Supporting+ PP3). Conclusion:The c. 11098C>T (p.R3700C) and c. 11039T>C (p.F3680S) compound heterozygous variants of the PKD1 gene probably underlay the ADPKD in the fetus. Above finding has provided guidance for the genetic counseling and prenatal diagnosis for this pedigree.

Angiokinases, such as vascular endothelial-, fibroblast- and platelet-derived growth factor receptors (VEGFRs, FGFRs and PDGFRs) play crucial roles in tumor angiogenesis. Anti-angiogenesis therapy using multi-angiokinase inhibitor has achieved great success in recent years. In this study, we presented the design, synthesis, target identification, molecular mechanism, pharmacodynamics (PD) and pharmacokinetics (PK) research of a novel triple-angiokinase inhibitor WXFL-152. WXFL-152, identified from a series of 4-oxyquinoline derivatives based on a structure-activity relationship study, inhibited the proliferation of vascular endothelial cells (ECs) and pericytes by blocking the angiokinase signals VEGF/VEGFR2, FGF/FGFRs and PDGF/PDGFR simultaneously . Significant anticancer effects of WXFL-152 were confirmed in multiple preclinical tumor xenograft models, including a patient-derived tumor xenograft (PDX) model. Pharmacokinetic studies of WXFL-152 demonstrated high favourable bioavailability with single-dose and continuous multi-dose by oral administration in rats and beagles. In conclusion, WXFL-152, which is currently in phase Ib clinical trials, is a novel and effective triple-angiokinase inhibitor with clear PD and PK in tumor therapy.

Objective To investigate the effect of early involvement in clinical practice in improving comprehensive abilities of medical students and strengthening their occupational cognition. Methods The students in the 5-year class of 2014 of pediatrics in our university were enrolled as subjects, among whom 78 students who received early involvement in clinical practice and teaching were enrolled as experimental group and 81 students who did not receive such teaching were enrolled as control group. A questionnaire survey was performed for the students participating in the teaching, including basic information, pre-training quality evaluation, development of personal knowledge and abilities, and comments or suggestions. The two groups were compared in terms of the score of the theoretical course of pediatric surgery, so as to explore whether"early involvement in clinical practice"could improve the theoretical study of students. Finally, the performance of students in clinical practice was evaluated and compared between the two groups to assess the role of "early involvement in clinical practice" in improving comprehensive abilities and occupational cognition. Results More than 90%of the students were satisfied with early involvement in clinical practice and they thought this activity helped them to improve clinical thinking, strengthen occupational cognition, enhance learning interests, improve communication skills, and promote the combination of basic and clinical knowledge. In addition, the follow-up analysis found that compared with the control group, the experimental group had a significantly higher average score [(74.59 ±0.50) vs. (68.89 ±0.67)] and a significantly higher proportion of students with a score of >70, and no students failed. As for the score of clinical practice, the experimental group had significantly better clinical work proficiency, clinical thinking, operational ability,and doctor-patient communication ability than the control group. Conclusion Early involvement in clinical practice among medical students can improve their comprehensive abilities and help to cultivate clinical thinking and doctor-patient communication skills and strengthen their occupational cognition, which lays a good foundation for cultivating high-quality talents through medical education.

Objective To evaluate combination of cholcdochoscopy or duodenoscopy with therapeutic laparoscopy (LCDCS) in treatment of detail choledochus stones. Methods Laparoscopic cholecystectomy was firstly performed and followed by choledochoscopy or duodenoscopy. Procedures of therapeutic choledochoscopy were as follows: choledochoscopic exploration via cystic duct remnant, choledochotomy, electrohydralic lithothipsy, drainage of bile duct with ureteral catheter via cystic duct remnant, T-tube drainage, or the suture of duct incision. Procedures of therapeutic duodenoscopy were as follows: access to the common bile duct and duodenum through ureteric catheter and zebra guidewire via cholecystic duct remnant, duodenoscopy via oral cavity into the duodenum papilla, papillotomy with needle-knife or arch-like electro-knife along the ureteric catheter or zebra guidewire, and stone clearance in the common bile duct with the reticulation and balloon of duodenescopy. Results Combination therapy were given to 191 cholelithiasis patients with detail choledochus stones. Combined choledochoscopy were performed in 117 patients. Stones were completely removed and average operation time was 114 min. Bile leakage occurred in 7 cases, but was cured with drainage. Postoperative imaging showed 2 cases of bile duct stenosis at primary closure of duct incision. Combined duodenescopic procedures were performed in 74 patients. Papillotomy and stone clearance were successfully performed in 68 patients, 5 others of whom underwent successful papillotomy only, and another underwent other operations. Average operation time was 97 min. Post-operation mild acut pancreatitis developed in 6 patients. No perforation of intestine or bile duct, bleeding, severe pancreatitis, or death was observed in each group. Conclusion LCDCS was safe and effective with appropriate indications.
