Objective UPLC-Q-TOF-MS integrated molecular network strategy was used to rapidly analyze and identify the chemical components of Yuye detoxification Particle. Methods The secondary mass spectrometry data of compounds were obtained using mass spectrometry scanning in both positive and negative ion mode. The similarity of MS/MS fragmentation patterns was calculated to create the global natural product social molecular networking (GNPS) platform. The major components in Yuye detoxification Particle were quickly identified according to the molecular clusters with similar structures in GNPS. Manual analysis and identification of other compounds were performed according to the mass fragment ion information of the primary and secondary mass spectrum data and related references by using the molecular feature extraction (MFE) function of Agilent Masshunter Qualitative Analysis workstation and traditional Chinese Medicine composition database (TCM-DATA). Results A total of 89 compounds in Yuye detoxification Particle were identified by LC-MS,including 22 phenoliacids,21 flavonoids and their glycosides,6 iridoid glycosides,28 triterpenoid saponins and 12 other types of ingredients. Conclusion UPLC-Q-TOF-MS/MS integrated molecular network technology can be used for rapid and systematic identification of chemical components of Yuye detoxification Particle,which provides theoretical basis for its quality control and clinical application. The established molecular network can provide reference for rapid qualitative analysis of components of traditional Chinese medicine compound.

Objective:
To analyze the clinical phenotype and genomic abnormality of an adult featuring congenital heart defect and multiple developmental disorders.
Methods:
The patient was subjected to conventional G-banding chromosomal karyotyping and single nucleotide polymorphism microarray (SNP-array) analysis.
Results:
The patient showed a normal karyotype, while SNP-array revealed a 42.7 Mb mosaic uniparental disomy (UPD) in the 11p15.5p12 region ([hg19] chr11: 491 333 - 43 189 376).
Conclusion
The mosaicism of UPD of 11p15.5p12 region probably underlies the congenital heart defect and developmental disorders in the patient.

The pharmaceutical co-crystal has attracted a lot of attention in recent years as a new direction in the research of polymorphism drugs. The research on pharmaceutical co-crystal has scientific significance for improving the solubility, bioavailability and physical or chemical stability of drugs. In this paper, from the perspective of drugs for the treatment of cardiovascular diseases(including five major types: heart failure, hypertension, coronary heart disease and arrhythmia, stroke) , the latest research results of pharmaceutical co-crystal reported in recent years are reviewed, hope to provide reference for the follow-up research and promote the development of pharmaceutical co-crystal in China.

Objective:To explore the clinical efficacy of a retrograde pubic ramus intramedullary nail (RPRIN) in the treatment of anterior pelvic ring fractures.Methods:A retrospective study was conducted to analyze the 14 patients with anterior pelvic ring fracture who had been treated and followed up at Department of Traumatic Surgery, Tongji Hospital From June 2020 to February 2021. There were 10 males and 4 females with an age of (44.8±12.5) years. By the AO/OTA classification for pelvic fractures, 5 cases were type 61-A, 4 cases 61-B, and 5 cases type 61-C; by the Nakatani classification, 1 case belonged to unilateral zone Ⅰ fracture, 5 cases to unilateral zone Ⅱ fracture, 2 cases to unilateral zone Ⅲ fracture, 3 cases to right zone Ⅱ and left zone Ⅲ fracture, 2 cases to zone Ⅲ fracture on both left and right sides, and 1 case to zone Ⅱ fracture on both sides. The time from injury to operation was (7.8±1.8) days. All the anterior pelvic ring fractures were fixated with a RPRIN. The time and fluoroscopic frequency for placement of every single RPRIN, quality of fracture reduction, and pelvic function and incidence of postoperative complications at the last follow-up were recorded.Results:A total of 18 RPRINs were placed in the 14 patients. For placement of each RPRIN, the time was (35.9±8.6) min, and the fluoroscopic frequency (22.8±1.9) times. No complications such as infection occurred at any surgical incision after RPRIN placement. According to the Matta scoring, the quality of postoperative fracture reduction was assessed as excellent in 7 cases, as good in 5 cases and as fair in 2 cases. The 14 patients were followed up for (18.1+1.5) months. Their X-ray and CT images of the pelvis at the last follow-up showed that the fractures healed well and the intramedullary nails were placed in the cortical bone of the anterior ring of the pelvis. According to the Majeed scoring at the last follow-up, the pelvic function was assessed as excellent in 10 cases, as good in 3 cases and as fair in 1 case. One patient reported discomfort during squatting 2 months after operation but the symptom improved 3 months later without any special treatment. No patient experienced such complications as displacement or slippage of RPRIN, or pain at the insertion site.Conclusion:RPRIN is effective in the treatment of anterior pelvic ring fractures, showing advantages of small surgical incision, limited intraoperative fluoroscopy and short operation time.
