To evaluate the application of intracavitary three-dimensional ultrasonography in the diagnosis of polycystic ovary syndrome ( PCOS). The three-dimensional volumes of ovary were measured by intracavitary ultrasonography in 40 PCOS patients and 40 normal controls. The diagnostic value of parameters derived from three-dimensional ultrasonography was evaluated by using the receiver operating characteristic (ROC) curve. The ovarian volume, stromal volume, and the stromal/total volume ratio in PCOS group were significantly higher than those in control group (both P < 0. 05 ) ; the area under ROC curve ( AUC ) of them were 0. 876, 0. 926, 0. 886 respectively. Among these parameters, stromal volume had the highest diagnostic value for PCOS, the cut-off value of which was 7.52 cm3 with a sensitivity of 88% and a specificity of 90%. Volume parameters of ovary measured by intracavitary three-dimensional ultrasonography can offer quantitative information for the diagnosis of PCOS.

Objective:To investigate the application of a video laryngoscope combined with a fiberoptic bronchoscope in emergency endotracheal intubation and its effects on pulmonary infection in patients with craniocerebral trauma.Methods:A total of 105 patients with craniocerebral trauma who received treatment in Yiwu Central Hospital from January 2020 to December 2020 were included in this study. They were randomly allocated to undergo endotracheal intubation with a video laryngoscope (control group, n = 50) or a video laryngoscope combined with a fiberoptic bronchoscope (observation group, n = 55). Glottic exposure, intubation, vital signs, lung infection rate during hospitalization, and incidence of complications were monitored/determined in each group. Results:Glottic exposure in the observation group was superior to that in the control group ( Z = 4.29, P < 0.001). First-pass success rate was significantly higher in the observation group than in the control group [96.36% (53/55) vs. 82.00% (41/50), χ2 = 5.76, P < 0.05]. The number of intubation attempts and the time to successful intubation were (1.07 ± 0.53) times and (85.12 ± 15.36) seconds, respectively in the observation group, which were significantly less or shorter than those in the control group [(1.92 ± 0.74) times, (106.13 ± 16.34) seconds, t = 6.81, 6.79, both P < 0.001). The changes in mean arterial pressure and heart rate during intubation were less in the observation group than in the control group (both P < 0.05). The amplitude of increase in blood oxygen saturation after intubation was greater in the observation group than in the control group ( P < 0.05). Lung infection rate was significantly lower in the observation group than in the control group [10.91% (6/55) vs. 30.00% (15/50), χ2 = 5.96, P < 0.05]. The incidence of complications was significantly lower in the observation group than in the control group [5.45% (3/55) vs. 18.00% (9/50), χ2 = 4.07, P < 0.05]. Conclusion:Application of a video laryngoscope combined with a fiberoptic bronchoscope in emergency endotracheal intubation can increase the first-pass success rate, reduce repeated intubation attempts, shorten time to successful intubation, help to maintain stable vital signs, prevent lung infection and complication. Therefore, the combined method is of clinical application value.

OBJECTIVE:
To analyze the phenotype and genetic variant in a pedigree affected with inherited protein C (PC) deficiency.
METHODS:
The proband and her family members (7 individuals from 3 generations) were tested for plasma protein C activity (PC:A), protein C antigen (PC:Ag) content and other coagulation indicators. All of the 9 exons and flanking sequences of the proband's PROC gene were amplified by PCR and sequenced. Suspected variants were verified by reverse sequencing of the proband and her family members. Bioinformatic software was used to analyze the pathogenicity and conservation of the variant site. Swiss-PdbViewer was used to analyze the three-dimensional model and the interaction with the mutant amino acid.
RESULTS:
The PC:A and PC:Ag of the proband, her grandmother, father and elder brother were decreased to 55%, 52%, 48%, 51% and 53%, 55%, 50%, 56%, respectively. Genetic analysis showed that the four individuals have all carried heterozygous c.1318C>T (p.Arg398Cys) missense mutation in exon 9 of the PROC gene. The score of MutationTaster was 0.991, PROVEAN was -3.72, and FATHMM was -2.49, all predicted it to be a harmful mutation. Phylogenetic analysis also showed that Arg398 was weakly conservative among homologous species. Protein model analysis showed that, in the wild type, Arg398 can form a hydrogen bond with Glu341 and Lys395 respectively, when it was mutated to Cys398, the hydrogen bond with Glu341 disappears and an additional hydrogen bond was formed with Lys395, which has changed the spatial structure of the protein.
CONCLUSION
The heterozygous missense mutation c.1318C>T (p.Arg398Cys) of the PROC gene probably underlay the decreased PC:A and PC:Ag in this pedigree.
