Objective To investigate the three-dimensional morphological characteristics of tibial plateau based on CT image post-processing technique and analyze its significance in preoperative planning of tibial plateau fractures.Methods Multi-slice spiral CT data of 98 humans (56 males and 42 females) with normal tibial plateau and 30 patients (15 males and 15 females) with tibial plateau fractures were extracted.Morphological measurements of the tibial plateau were achieved by means of a three-dimensional measurement method based on points,lines and surfaces.Differences in threedimensional parameters between genders in normal tibial plateau and differences between normal tibial plateau and tibial plateau fractures were analyzed.Results Differences of males and females were significant in width of tibial plateau [(73.2 ± 3.7) mm,(65.5 ± 3.7) mm],anteroposterior dimension of medial tibial plateau [(39.8 ± 3.5) mm,(34.8 ± 2.6) mm] and anteroposterior dimension of lateral tibial plateau [(34.0 ± 3.3) mm,(29.8 ± 3 5) mm] (P ＜ 0.05),but not in varus inclination of tibial plateau [(3.19 ± 1.98) °,(3.16 ± 1.89) °],medial plateau posterior slope [(7.31 ± 3.04) °,(8.16 ± 2.46)°] and lateral plateau posterior slope [(5.23 ±2.35)°,(5.60 ±2.55)°] (P ＞0.05).Above parameters in three-dimensional morphological measurements of tibibial plateau fractures varied compared to the normal reference value (P ＜ 0.05).Intraclass correlation coefficient (ICC) for intra-observe and inter-observer agreement in normal tibial plateau measurement was excellent.Conclusions Present research provides a series of scientific and objective data for preoperative planning of tibial plateau fractures.Measurements of tibial plateau can assist the evaluation of reduction of tibial plateau fractures.

Objective To explore the impact of prenatal diagnosis on the early treatment and short and medium term outcome of neonatal pulmonary atresia with intact ventricle septum (PA/IVS) or critical pulmonary stenosis with intact ventricle septum (CPS/IVS). Methods According to the case-control method, twenty-eight neonates with (PA/IVS) or (CPS/IVS) who had percutaneous pulmonary balloon valvuloplasty (PBPV) surgery indications, were divided into the prenatal diagnosis group (n?=?15) and the postnatal diagnosis group (n?=?13). The prenatal diagnosis group was diagnosed in fetal period and the intervention program was since developed . The postnatal diagnosis group was referred from other hospitals, and the intervention program was developed after conifrmation of the diagnosis. All the neonates accepted the PBPV surgery after the hemodynamic parameters stable. All neonates were followed-up at 1 month, 3 months, 6 months, 1 year, and 2 years after surgery. Clinical situations, echocardiography results, and interventional cardiology measurements were compared between two groups. Result The average age and weigh was 7.53?±?3.18 days and 3102.32?±?708.40 g respectively at the time of PBPV surgery in 28 neonates. Among them, 9 neonates were PA/IVS and 19 neonates were CPS/IVS. The mean follow-up time was 18.8?±?5.22 months and there were no death. The ages at admission and at the ifrst treatment were signiifcantly younger in the prenatal diagnosis group than those in the postnatal diagnosis group (P??0.05). Conclusion Prenatal diagnosis is helpful for the early intervention in neonates with PA/IVS and CPS/IVS, and can reduce the complications after surgery.

italic>Artemisia argyi (A. argyi) is a Chinese herbal medicine in China. The main active components are volatile oils, flavonoids, and other compounds, which have various pharmacological activities. Methoxylated flavonoids are the main active ingredients in A. argyi. Flavonoid O-methyltransferase (FOMT) is a key enzyme in the O-methylation of flavonoids. In order to further understand the function and characteristics of FOMT proteins, this paper carried out the whole genome mining and identification of FOMT genes in A. argyi and performed phylogenetic, chromosomal localization, gene sequence characterization, subcellular localization prediction, protein structure, gene structure analysis, and expression pattern analysis. The results showed that a total of 83 FOMT genes were identified in the genome of A. argyi. The phylogenetic tree shows that FOMT genes are divided into two subgroups, CCoAOMT (caffeoyl CoA O-methyltransferase) subfamily (32 genes) and COMT (caffeic acid O-methyltransferase) subfamily (51 genes). Gene sequence analysis showed that the number of amino acids encoded by FOMT was 70-734 aa, the molecular weight was 25 296.55-34 241.3 Da, and the isoelectric point was 4.51-9.99. Compared with 32 members of the CCoAOMT subfamily, nearly 1/3 of the 51 members of the COMT subfamily were hydrophobic proteins and 2/3 were hydrophilic proteins. Subcellular localization prediction showed that more than 80% of CCoAOMT subfamily members were located in the cytoplasm, and 96% of COMT subfamily members were located in the chloroplast. COMT subfamily members have more motifs than CCoAOMT subfamily members. The N-terminal motifs of COMT subfamily proteins are relatively variable, while the C-terminal motifs are relatively conserved. Expression pattern analysis showed that CCoAOMT subfamily members were mainly expressed in roots, while COMT members were mainly expressed in leaves. Some FOMTs showed the tissue expression specificity by real-time quantitative PCR analysis, especially in leaves. In this study, we identified and analyzed the FOMT gene family in A. argyi, and provided a theoretical basis for further research on the function of FOMTs and the biosynthesis of methylated flavonoids in A. argyi.
