Objective:To study the cardiac morphology and function of fetuses with different types of complete transposition of the great arteries（cTGA）by using fetal heart quantification（fetal HQ）.Methods:A retrospective study was conducted on 50 fetuses diagnosed with cTGA through fetal echocardiography at Sir Run Run Shaw Hospital，Zhejiang University School of Medicine from July 2020 to December 2024. These cases were categorized into simple cTGA group（ n=31）and complex cTGA group（ n=19）based on the presence of concomitant cardiac anomalies. A control group of 160 normal fetuses with matched gestational ages was selected for comparison. Utilizing fetal HQ technology，the cardiac longitudinal diameter，transverse diameter，area，global sphericity index（GSI），left and right ventricular end-diastolic area（LVEDA，RVEDA），left and right ventricular fractional area change（LVFAC，RVFAC），left and right ventricular global longitudinal strain（LVGLS，RVGLS），and segmental sphericity index of 24 segments for both left and right ventricles（LVSI，RVSI）were measured. The analysis focused on comparing the differences among the simple cTGA group，complex cTGA group，and the control group. Results:Compared to the control group，the simple cTGA group exhibited significantly lower fetal GSI，LVEDA，RVFAC，and RVGLS（all P<0.05）. Statistically significant differences were observed in LVSI segments 1-4 and 10-17，as well as RVSI segments 1-7，9，and 15-23 compared to the control group（all P<0.05）. In comparison with the control group，the complex cTGA group demonstrated significantly reduced fetal GSI，LVFAC，LVGLS，RVFAC，and RVGLS（all P<0.05）. Significant differences were noted in LVSI segments 5-8 and 10-14，along with RVSI segments 1-14 and 24 compared to the control group（all P<0.05）. When compared to the simple cTGA group，the complex cTGA group showed significantly lower LVFAC，LVGLS，RVFAC，and RVGLS（all P<0.05），while GSI and LVEDA were significantly higher（all P<0.05）. Statistically significant differences were observed in LVSI segments 3-4，6-8，and 17，as well as RVSI segments 10-19 between the complex cTGA group and the simple cTGA group（all P<0.05）. Conclusions:The comprehensive parameters provided by Fetal HQ facilitate the assessment of cardiac morphology and function in cTGA fetuses，enabling a deeper understanding of the alterations in cardiac structure and function across different types of cTGA. This advanced analysis offers valuable reference information for clinical guidance during pregnancy.

Objective To investigate the knowledge,attitude,and behavior(Knowledge-Attitude/belief-Practice,KAP)of residents in Hezhou City regarding the safety risks of using traditional Chinese medicine(TCM).Methods A stratified cluster random sampling method was used to select residents from different areas of Hezhou City.A questionnaire based on the KAP model was designed for the survey.Descriptive analysis,univariate analysis,and multiple linear regression analysis were conducted to explore the factors influencing the KAP of TCM safety behavior.Results Among the 2 000 questionnaires distribu-ted,all were conducted online.Of these,98 were incomplete,resulting in a total of 1 902 valid responses,with a valid response rate of 95.10％.In the survey of 2 000 residents of Hezhou City,the average knowledge score was(54.34±2.50),the average behavior score was(64.32±2.44),and the average attitude score was(62.44±3.07).The differences in knowledge scores among residents with different places of residence,educational levels,medical insurance status,monthly incomes,and other de-mographic characteristics were statistically significant(P＜0.05).The differences in behavior scores among residents with differ-ent medical insurance status and occupations were statistically significant(P＜0.05).The differences in attitude scores among residents with different monthly incomes and medical insurance status were also statistically significant(P＜0.05).Results of multiple linear regression analysis indicated that place of residence,medical insurance(self-paid),educational level(junior high school and below),and monthly income(below 2 000 yuan,2 001-4 000 yuan)were influencing factors for the knowledge score on safe use of proprietary Chinese medicines(P＜0.05).Medical insurance(self-paid)and occupation(enterprise work-er,freelancer,student)were influencing factors for the behavioral risk score regarding safe use of proprietary Chinese medicines(P＜0.05).Medical insurance(self-paid)and monthly income(below 2 000 yuan)were influencing factors for the attitudinal risk score regarding safe use of proprietary Chinese medicines(P＜0.05).Conclusion The overall KAP level regarding the safety of using traditional Chinese medicine among residents in Hezhou City is relatively low,and medication safety is closely re-lated to place of residence,medical insurance,monthly income,occupation,etc.

Objective:To evaluate the fetal heart shape and function in tetralogy of Fallot (TOF) by fetal heart quantitative analysis (fetal HQ).Methods:A total of 52 fetuses with TOF diagnosed by fetal echocardiography and 200 normal fetuses matched with their gestational weeks from March 2020 to March 2022 at Sir Run Run Shaw Hospital, Zhejiang University were retrospectively evaluated. The basic parameters of fetal cardiac blood vessels in the two groups were measured by fetal HQ technology and conventional M-mode ultrasound technology: aortic valve diameter(AV), pulmonary artery valve diameter(PV), main pulmonary artery diameter (MPA) and Z-score. The overall morphometric measurements including end-diastolic length diameter, transverse diameter, area, and global spherical index (GSI) of the fetal heart in the 4-chamber view(4CV), area and length of the right and left ventricles and their ratios. Measurements of left and right ventricular function included ejection fraction (EF), fraction area change rate (FAC), tricuspid annular plane systolic excursion (TAPSE), left and right ventricular global longitudinal strain (GLS), and left and right ventricular end-diastolic diameter (ED), spherical index (SI), and fractional shortening rate (FS) of 24-segments. The differences of above parameters between TOF group and control group were compared. In addition, the relationships between the absolute value of left and right ventricular GLS of TOF fetus and PV/AV, PV Z-score and MPA Z-score were analyzed. The optimal critical values of GSI, left ventricular EF and left ventricular FAC of TOF fetus were determined by ROC curve, and their corresponding sensitivity and specificity were obtained.Results:Compared with control group, there were significant differences in 4CV end-diastolic length, area, GSI, left ventricular area, left ventricular length, left ventricular EF, left ventricular FAC and left ventricular GLS in TOF group (all P<0.05). There were significant differences in ED between left ventricular 15-24 segments and right ventricular 1-21 segments (all P<0.05). There were significant differences in SI between left ventricular 1-16 segments, 21-24 segments and all segments of right ventricle (all P<0.05). The differences in FS were statistically significant (all P<0.05) when comparing all segments of the left ventricle and 1-2 segments of the right ventricular, and the remaining parameters were not statistically significant (all P>0.05). The left ventricular GLS absolute value of TOF fetuses was positively correlated with PV/AV, PV Z-score and MPA Z-score( rs=0.338, 0.441 and 0.458, all P<0.05), the right ventricular GLS absolute value of TOF fetuses was positively correlated with PV AV, PV Z-score and MPA Z-score( rs=0.418, 0.368 and 0.338, all P<0.05). The optimal critical values of GSI, left ventricular EF, and left ventricular FAC in the diagnosis of fetal TOF were 1.19, 59.05%, and 44.4%, respectively. At this time, the sensitivities of diagnosis of TOF were 0.78, 0.75, and 0.80, respectively. The specificities were 0.88, 0.88 and 0.83, respectively. The areas under ROC curve were 0.89, 0.88 and 0.89, respectively. Conclusions:Fetal HQ technology can provide a simple and reliable quantitative evaluation of fetal heart shape and function, and provide certain theoretical parameters for the study of fetal heart shape and function.

OBJECTIVETo evaluate the effect of aorta-iliac bypass total thoracoabdominal aorta aneurysm repair to spinal cord function.

METHODSThis was a prospective study. From June 2014 to April 2015, 31 patients underwent total thoracoabdominal aorta aneurysm repair were treated with aorta-iliac bypass technique. There were 23 male and 8 female patients with a mean age of (36±12) years. A 4-branched tetrafurcate graft was used. The aorta-iliac bypass was established, then distal descending aorta was perfused in a retrograde fashion via bypass graft. Thoracic and abdominal aorta were replaced in a staged fashion. Evoked potentials (EP) monitoring was adopted to assess the spinal cord ischemia throughout the procedure. The intraoperative evoked potentials results, clinical outcomes and follow-up results of this technique were evaluated.

RESULTSThe EP wave disappeared after proximal descending aorta clamped and gradually recovered after the patent segmental arteries reattached. Motor evoked potentials disappeared for (56±18) minutes, somatosensory evoked potentials disappeared for (50±19) minutes. The EP wave was restored to normal at the end of operation in all cases. The somatosensory evoked potentials remained unchanged in 2 cases (false negative). One case died after operation. There were acute kidney dysfunction in 3 cases, and pulmonary haemorrhage in 1 case. No spinal cord injure occurred. The median follow-up after operation was 8 months (ranging from 1 to 11 months). There was no delayed neurologic deficit or relative death.

CONCLUSIONSThere is a transient function loss of spinal cord during the aorta-iliac bypass total thoracoabdominal aorta aneurysm repair. But the process is reversible. The technique of the aorta-iliac bypass is practicable.
