Objective:To explore the feasibility of fetal intelligent navigation echocardiography (FINE) in automatic quantitation of cardiac axis (CA).Methods:A total of 62 pregnant women of which 2 with twins′ pregnancy in the second and third trimesters from May to June 2020 in Sir Run Run Shaw Hospital Zhejiang University College of Medicine were enrolled in this non-selective and prospective study. After excluding those who could not be analyzed, they were assigned into four groups according to their CA measuring methods: ①Group with manual measuring CA in systole (CAS); ②Group with manual measuring CA in diastole(CAD); ③Group with CA measured by FINE in three-steps; ④Group with CA measured by FINE in seven-steps. The CAS among groups were compared in order to analyze the consistency and correlation of CAS achieved by different methods, meanwhile, the intra-observer and inter-observer consistency and repeatability were also evaluated.Results:A total of 64 fetuses with 187 volume data were collected, of which 60 cases of fetal data can be included in the study, 57 cases of normal CA, 3 cases of abnormal CA, a total of 158 volume data can be used for data analysis, the success rate was about 84.5%. Because of the small number of abnormal CA cases (3 cases), only 57 cases of normal CA were statistically analyzed in this study. Three-step and seven-step FINE automatic quantitative CA showed significantly different from those obtained with manual measurements of CAD ( P=0.005, P<0.001). There were no significant differences in quantitative analysis of CA between three-step or seven-step FINE and manual measurements of CAS ( P=0.458, 0.883), however, there was no correlation between CA using three-step FINE and manual measurement of CAS ( rs=0.056, P=0.679), but there was a positive correlation between CA using seven-step FINE and manual measurement of CAS ( rs=0.599, P<0.001). The linear regression equation was constructed as follows: Y=10.96+ 0.73 X ( R2=0.431, P<0.001). There was no correlation between three-step method and seven-step method for automatic quantitative CA ( rs=0.158, P=0.241). There was significant difference( P<0.001), but strong correlation between manual measurement of CAS and manual measurement of CAD ( rs=0.973, P<0.001), the average difference was ΔCA=(4.5± 3.8)°. The linear regression equation was constructed as follows: Y=-2.94+ 0.96 X ( R2=0.950, P<0.001). Intra-observer and inter-observer measurements had shown no significant difference in consistency and repeatability (all P>0.05). Conclusions:The measurement of fetal CA by seven-step FINE is superior to the three-step FINE when the fetal CA is in normal range. This may be considered a promising aspect that seven-step FINE automatic quantitation of fetal CA can replace the manual measurement of CAS. Future research is needed to deliminate the reliability of automatic quantification of fetal CA by seven-step FINE with the CA in abnormal range.

Objective To explore the value of blood inflammatory load in predicting overall survival of elderly patients with epithelial ovarian cancer (EOC). Methods Elderly patients with EOC were selected, and their clinical data and peripheral blood parameters were collected. We constructed an inflammation-related blood scoring system using univariate and multivariate Cox regression analysis. The Kaplan-Meier method was used for survival analysis. We used Cox proportional hazards analysis to identify the independent prognostic factors. A nomogram model was constructed based on independent prognostic factors, and the receiver operating characteristic curve, C-index, and calibration curve were used to evaluate the model. Results Patients with high blood inflammatory load had worse prognosis (P=0.002). Compared with the low inflammatory load group, patients with high inflammatory load had later clinical stages and larger ascites volume (P<0.05). Cox regression analysis showed that ACCI, CA125, residual lesions, and blood score were independent factors affecting overall survival (P<0.05). Conclusion The blood inflammatory load is the biomarker for the prognosis of elderly patients with EOC. Scoring the inflammatory load in the blood can assist in efficacy monitoring and treatment intervention of ovarian cancer patients.

Objective: To observe the effects of functional training combined with self-made hand flexing training band in treatment of scar contracture after burn injury of dorsal hand. Methods: Forty-six patients with scar contracture after deep partial-thickness or full-thickness burn injury of dorsal hand hospitalized in our department from March 2013 to February 2015 were divided into routine training group (RT, n=18) and comprehensive training group (CT, n=28) according to their willingness. Two weeks after the wounds were healed, patients in group RT were treated with functional training of hands and self-made pressure gloves, while patients in group CT were treated with self-made hand flexing training band (consisting of nylon strap, flexing band, and velcro) on the basis of those in group RT. All patients were treated for 3 months. Before and after treatment, scar condition of affected hands was assessed with Vancouver Scar Scale (VSS). The range of motion of joints of affected hands was measured by Total Active Movement (TAM) Scale. The function of affected hands was evaluated by Carroll Upper Extremity Function Test. Data were processed with t test, chi-square test, and Mann-Whitney U test. Results: (1) The score of VSS in patients of group RT was (10.0±1.9) points before treatment and (4.4±1.4) points after treatment, with the improved score of (5.6±1.0) points. The score of VSS in patients of group CT was (10.5±1.8) points before treatment and (4.6±1.4) points after treatment, with the improved score of (5.9±1.2) points. There was no statistically significant difference in the improved score of patients between the two groups (t=0.834, P>0.05). The score of VSS in patients of groups RT and CT after treatment was significantly lower than that before treatment (with t values respectively 14.014 and 10.003, P values below 0.01). (2) Before treatment, the ratios of excellent and good results according to TAM were 2/9 in patients of group RT and 3/14 in group CT, with no statistical differences between them (χ²=2.140, P>0.05). After treatment, the ratio of excellent and good results according to TAM in patients of group CT (6/7) was higher than that in group RT (5/9, χ²=0.023, P=0.038). The ratios of excellent and good results according to TAM in patients of groups RT and CT after treatment were significantly higher than those before treatment (with Z values respectively -2.023 and -4.780, P values below 0.05). (3) The improved score of hand function in patients of group CT was (26±12) points, which was higher than (15±7) points in group RT (t=3.278, P=0.002). The score of hand function in patients of groups RT and CT after treatment was significantly higher than that before treatment (with t values respectively 2.628 and 6.125, P values below 0.05). There were no significant differences in grades of hand function of patients between the two groups before treatment (Z=-0.286, P>0.05). After treatment, the grade of hand function in patients of group CT was higher than that in group RT(Z=-1.993, P=0.046). The grades of hand function in patients of groups RT and CT after treatment were significantly higher than those before treatment (with Z values respectively -2.717 and -4.998, P values below 0.01). Conclusions For patients with scar contracture after burn injury of dorsal hand, early functional training combined with hand flexing training band can improve the range of motion of hand joints and functional recovery of hand, and the result was better than functional training alone.

Objective:To explore the application value of fetal heart quantification (fetal HQ) in evaluation of fetal cardiac function and morphology in fetuses with left ventricular outflow tract obstruction (LVOTO).Methods:Twenty-five fetuses with LVOTO diagnosed by fetal echocardiography in Sir Run Run Shaw Hospital, Zhejiang University Medical College from April to July 2020 were enrolled. The end-diastolic basal apical length(BAL), transverse length (TL), global spherical index (GSI) of fetal four-chamber view, and the left and right ventricular end-diastolic area, long diameter, 24-segment end-diastolic transverse length (ED) and its Z-scores adjusted by gestational age and 24-segment spherical index(SI) were calculated by using fetal HQ. Subsequently the Z-scores of left and right ventricle fractional shortening (FS) in 24 segments were obtained by gestational age.Results:SI of 24-segments of left ventricles in fetuses with LVOTO were significantly different from that of right ventricles (all P<0.05). There was significant difference between left and right ventricular areas ( P<0.05). There was no significant difference between left and right ventricular lengths ( P>0.05). There were significant differences between the 24-segment Z-scores of left and right ventricular ED(all P<0.05). The ratios of RVED to LVED of 24 segments were analyzed by box diagram. The results showed that the transverse length of right ventricle was significantly higher than that of left ventricle. The highest value was 1.49(1.26-1.86), and the lowest value was 1.40(1.26-1.86), both significantly higher than the normal value of 1.19. There were no significant differences between the 1-19-segment Z-scores of left and right ventricular FS( P>0.05). There were significant differences between the 20-24-segment Z-scores of left and right ventricular FS( P<0.05). Conclusions:Fetal HQ can be used to quantitatively analyze left ventricular shape, size and function of fetuses with LVOTO, which provides a new method for quantitative analysis of fetal heart function.

Objective: To evaluate the clinical efficacy of modified lateral window for maxillary sinus floor augmentation (MSFA). Methods: Fifty-five patients who visited the Stomatology Hospital Affiliated to Zhejiang University School of Medicine between June 2012 and October 2014 were enrolled in the study. Patients underwent MSFA with Bio-Oss grafts based on modified access window. During the operation the vertical height of the bony window was reduced from 6-8 mm of conventional oval window to 4-5 mm of slot-shaped window. The sinus membrane was detached completely via the lateral access and large particle Bio-Oss graft was placed in the sub-mucosal space. The implant survival, graft height, graft volume and resorption rates were measured. Intra-op and post-op complications were recorded. Results: There were 86 implants inserted. The 2-4 year cumulative survival rates were 97.67% by implant-based analysis and 96.36% by patient-based analysis. The residual bone height was (4.7±2.6) mm and bone width was (8.4±2.7) mm. The bone height of implantation site immediately after operation was (16.1±2.5) mm and it was (16.2±2.2) mm at restoration. The bone heights at 1 and 2 years after operation were (14.9±2.5) mm and (13.6±2.6) mm, respectively. The graft height was (10.6±2.8) mm and the graft volume was (1569±745) mm³ immediately after operation. The resorption rate of graft height 6 months after operation was 3.79% and that of graft volume was 7.87%. The 1-year accumulative resorption rate of graft height was 6.63% and that of graft volume was 10.89%. The 2-year accumulative resorption rate of graft height was 7.58% and that of graft volume was 15.26%. Small membrane perforation during MSFA was observed in 5 cases and all were successfully repaired by a collagen Bio-Gide membrane. Conclusion: The modified lateral technique obtains high implant survival rate, excellent graft stability and low complication rate at 2-4 year clinical follow-up, indicating that it is a safe, predictable and minimally invasive surgical method for severe atrophic maxillary posterior dentition.
