Objective To explore the clinical value of transvaginal three-dimensional color Doppler ultrasound in assessing effects of Chinese herbal drugs on improving endometrial receptivity in patients with thin endometrium.Methods A total of 76 cases of patients diagnosed with thin endometrium in Jiangbei District Hospital of Traditional Chinese Medicine from June 2015 to October 2016 were selected and treated with Chinese herbal prescription for three months.The endometrial thickness,endometrial volume and blood flow indexes before and after treatment were measured by using transvaginal three-dimensional color Doppler ultrasound.Results After 3 months treatment,the endometrial thickness and endometrial volume were increased,and the pulse index (PI) and resistance index (RI) of endometrial blood flow were decreased,compared with those before treatment,there were statistically significant differences(P＜0.05).The results of three-dimensional color Doppler ultrasound indicates that after 3 months treatment the vascularization index (VI),flow index (FI) and vascularization flow index (VFI) were significantly higher than those before treatment,there were statistically significant differences (P＜0.05).Conclusion The Chinese herbal prescription could increase the thickness and volume of endometrium,augment blood supply,and improve endometrial receptivity significantly.Transvaginal color three-dimensional Doppler ultrasound is a convenient and objective method for evaluating clinical efficacy of Chinese herbal prescription in patients with thin endometrium,which has high practical value.

Objective To determine the risk factors associated with early allograft dysfunction (EAD) after liver transplantation. Methods We retrospectively analyzed the records of 138 patients who underwent liver transplantation from January 2006 to October 2016 in our department. Transplant recipients were divided into two groups:those who met the diagnostic criteria of EAD (EAD group) and those who did not (non-EAD group). We compared blood flow into the transplanted livers and other clinical features between the two groups using univariate and multivariate analysis. Results Intraoperative portal vein flow (PVF) maximum was significantly different between the two groups. Multivariate analysis revealed that intraoperative PVF maximum ＜1 600 mL/min was the only independent risk factor for the occurrence of EAD after liver transplantation in this cohort. Conclusion Intraoperative PVF maximum ＜1 600 mL/min is an independent risk factor for the occurrence of EAD after liver transplantation. Measuring intraoperative blood flow into the transplanted liver in liver transplant recipients may help identify patients at risk for developing EAD.

Objective:To study the sequence characteristics and genetic variation of a human respiratory syncytial virus (HRSV) subtype A genome in Beijing.Methods:The genomic RNA of HRSV from nasopharyngeal aspirate samples was sequenced and obtained a whole genome sequence of HRSV A subtype. The phylogenetic tree was constructed with reference sequences of other HRSV strains. The major proteins were compared and single nucleotide polymorphism analyzed. In addition, the N-glycosylationsites of F and G protein were predicted.Results:Phylogenetic tree and homology analysis results suggest that the HRSV strain (RSVA/Beijing-China/2017) was the A subtype ON1 genotype. Nucleotide and amino acid variation analysis showed that G protein, F protein and L protein had some substitutions. Analysis of amino acid variation sites showed that amino acid substitution (L142S) occurred at position 142 of G protein. For F protein, there were two substitutions, which were S105N in the P27 peptide (110-136aa) and C69Y in the antigen sites ? (62-69 aa and 196-210 aa). The prediction of N-glycosylation sites revealed that there were 5 N-glycosylation sites of F protein and 4 N-glycosylation sites of G protein in this strain.Conclusions:The HRSV strain obtained in Beijing belongs to A subtype ON1 genotype. The G, F and L proteins have large variations, and 22 amino acid substitutions have occurred in the G and F proteins.
