ABSTRACT
Objective:To study the clinical characteristics of cornual pregnancy and compare the effects of various surgical methods on the outcomes.Methods:This was a single-center retrospective study. The clinical records of patients with cornual pregnancy who underwent surgery in Peking Union Medical College Hospital from June 2012 to December 2020 were collected. Surgical interventions included curettage (guided by ultrasound or monitored by laparoscope), and cornuostomy/cornectomy (the surgical approach by laparoscopy or laparotomy). The baseline data, perioperative treatment and whether persistent ectopic pregnancy (PEP) occurred after surgery were collected and analyzed statistically.Results:A total of 109 patients with cornual pregnancy diagnosed by surgical treatment were included in this study, whose average age was (32.9±4.8) years. Among them, the incidence of postoperative PEP was 16.5% (18/109). The risk of PEP in multipara was significantly higher than that in nulliparous women ( OR=7.639, 95% CI: 2.063-28.279, P=0.001). The risk of PEP in patients with the maximum diameter of lesion<1.5 cm was significantly higher than that in patients with the maximum diameter of lesion≥1.5 cm ( OR=8.600, 95% CI: 2.271-32.571, P=0.002). Among all surgical approaches for cornual pregnancy, the proportion of PEP in curettage under ultrasound monitoring was the highest (56.0%, 14/25), which was higher than that in curettage under laparoscope monitoring (1/10; χ2=6.172， P=0.013); the proportion of PEP in curettage group (42.9%, 15/35) was higher than that in cornuostomy/cornectomy group (4.1%, 3/74; χ2=25.950， P<0.01). Neither salpingectomy in the operation nor the routine use of methotrexate (MTX) in perioperative period could significantly reduce the incidence of PEP (all P>0.05). Conclusions:Among the patients with cornual pregnancy, multipara, the maximum diameter of lesion<1.5 cm and ultrasound-guided curettage are the risk factors of PEP after operation. Cornuostomy or cornectomy is recommended for patients with cornual pregnancy. If the patients would perform the curettage operation, laparoscopic monitoring is recommended. For patients with possible satisfactory operation outcome, it is not recommended to use MTX as a routine preventing measure.
ABSTRACT
AIM:To provide rational evidence for the administration of warfarin in clinic by investigating the utilization of warfarin in our hospital.METHODS:By retrospective analysis,the prescription of warfarin in our hospital was obtained from November 2016 to February 2017 from the system for clinical pharmacist.The general situation of the inpatient,the diagnosis of disease,the use of warfarin,and the combination of drugs and the number of International Normalized Ratio (INR) were statistically and descriptively analyzed.RESULTS:In this investigation,200 patients were included,of whom 53％ were males and 47％ were females with an average age of (55.28 ± 13.56) years.Only 21％ of the average INR values reached the predicted range (2 ＜ INR ＜ 3) during hospitalization and the average dose of warfarin was (2.62 ± 0.60)mg.In patients with INR ＜ 2,there were 66.92％ of patients combined with more than one kind of drugs,which decreased the effect of warfarin.In patients with INR ＞ 3,there were 80％ of patients combined with more than one kind of drugs,which increased the effect of warfarin.CONCLUSION:The rate of warfarin compliance is low and the warfarin-drug interactions exert a great influence on the patients whose INR value did not reach the predicted range.Thus,to keep the drug safety of patients,more attention should be paid on drug interactions and direct personalized medicine using professional knowledge of pharmacy.
ABSTRACT
Objective To identify the differentially expressed genes in cardinal ligament between patients with pelvic organ prolapse ( POP) and postmenopausal women without POP by Human Genome Expression Chip and explore the potential molecular mechanism involved in POP.Methods From January to May,2007,cardinal ligament samples were obtained from 3 postmenopausal patients with POP-Q stage Ⅲ and 3 postmenopausal patients underwent hysterectomy due to other benign gynecologic diseases without POP in Peking Union Medical College Hospital.HE and Masson's trichrome staining was used to verify tissue origin and inspect histological changes.Those differentially expressed genes in cardinal ligaments were identified by Human Genome Chip and further interrogated with Gene Ontology (GO) and Pathway Analysis.Those remarkable expressed genes were confirmed by qRT-PCR.Results Alterations of ligament architecture in POP patients included disarrangement and collapse of smooth muscle bundles and collagen fibers.A total of 179 differentially expressed genes were screened between POP and non-POP cardinal ligament tissue,including 20 functional unknown genes.A total of 107 genes were upregulated in POP group,while 72 genes downregulated.Those differentially genes were revealed associated with multiple functional proteins and metabolic pathways by biological analysis.Among these,Wnt signaling pathway exhibited the most remarkable changes.Real-time quantitative PCR showed the genes of COL1Al,DKK1,SFRP1,FZD5,WNT16b in POP group (2.98 ±1.40,3.03 ±0.48,8.13 ±4.42,5.19 ±3.50,12.40± 3.88) were upregulated significantly compared with non-POP group (1.09 ±0.08,1/20 ±0.18,0.41 ± 0.51,0.87 ±0.24,1.40 ±0.47; P < 0.05 ).Conclusions The pathophysiology of POP is complex and associated with multiple functional proteins and metabolic pathways.Among these,the antagonist DKK1,SFRP1 in Wnt signaling pathway may contribute to a neurodegenerative role in POP development.
