OBJECTIVES:
The diagnostic value of ultrasonographic quantitative indicators of umbilical cord coiling, such as the umbilical coiling index (UCI) and pitch value, in identifying hypercoiling and predicting adverse pregnancy outcomes remains controversial. This study aims to evaluate the predictive value of UCI, pitch value, and the cerebroplacental ratio in pregnancies complicated by umbilical cord hypercoiling.
METHODS:
Pregnant women with densely coiled umbilical cords identified by routine obstetric ultrasound at Changsha Maternal and Child Health Hospital between November 2022 and November 2024 were enrolled. Complete clinical data, including UCI, pitch value, and cerebroplacental ratio (CPR), were collected. Pregnancy outcome scores were calculated, and newborns were categorized into the normal outcome group (n=177) and adverse outcome group (n=85), with the latter further subdivided into mild (n=51), moderate (n=19), and severe (n=15) subgroups. Differences in baseline data, UCI, pitch value, and incidence of CRP<1 were compared between groups and among subgroups. Correlations between UCI, pitch value, and adverse pregnancy outcomes were analyzed. Receiver operating characteristic (ROC) curve were used to assess the predictive performance of UCI, pitch value, CPR<1, and their combinations.
RESULTS:
Compared with the normal outcome group, the adverse outcome group had higher age, parity, parity, incidence of CPR<1, and UCI, while gestational age at delivery and pitch values were lower (all P<0.05). The incidence of obesity, gestational diabetes mellitus, and hypertensive disorders of pregnancy did not differ significantly between the 2 groups (all P>0.05). The normal outcome group showed lower UCI and higher pitch values than all 3 adverse outcome subgroups (all P<0.05), while differences among the 3 adverse subgroups were not significant (all P>0.05). UCI was positively correlated with adverse pregnancy outcomes (rs=0.350, P<0.05), whereas pitch value was negatively correlated (rs=-0.286, P<0.05). ROC curve analysis showed that the area under the curve (AUC) values for predicting adverse outcomes were 0.837 for UCI, 0.886 for pitch value, and 0.610 for CPR<1, with sensitivities of 77.6%, 82.4%, and 27.1% and specificities of 78.5%, 83.6%, and 94.9%, respectively. The combined UCI+CPR<1 and pitch value+CPR<1 models yielded AUCs of 0.841 and 0.886, with sensitivities of 78.8% and 81.2% and specificities of 78.5% and 84.2%, respectively. No significant differences were found between the AUCs of UCI and pitch value (P>0.05), but both outperformed CPR<1 alone (both P<0.001). The combined models showed no significant improvement over UCI or pitch value alone (both P>0.05), though both were superior to CPR<1 alone (both P<0.001).
CONCLUSIONS
Most umbilical cord hypercoiling cases had favorable outcomes, with UCI, pitch value, CPR<1 and their combinations demonstrating significant predictive value for adverse pregnancy outcomes.

Objective:Interruption of aortic arch(IAA)is a rare congenital heart disease.This study aims to investigate echocardiographic features and pathological ultrastructural characteristics of fetal IAA and to further analyze its pathological evolution. Methods:A retrospective analysis was conducted on prenatal echocardiographic,post-surgical,or autopsy findings of fetuses prenatally diagnosed with IAA.Prenatal echocardiographic tracking was used to observe the internal diameters and Z-scores of different segments of the aortic arch and the changes in the narrowed section.These observations were combined with autopsy and pathological findings to explore the potential intrauterine evolution of IAA and its cytological basis. Results:The study included 34 fetuses with IAA,with 3,3,and 28 fetuses prenatally diagnosed with aortic arch dysplasia(AAD),coarctation of aorta(CoA),and IAA,respectively.The 3 AAD and 3 CoA fetuses chose termination of pregnancy 1 to 2 weeks after prenatal ultrasound diagnosis,and autopsy confirmed IAA.Among the 28 fetuses prenatally diagnosed with IAA,6 cases of CoA progressively worsened,eventually evolving into type A IAA as observed through echocardiographic follow-up.The remaining 22 cases were diagnosed as IAA on the first prenatal ultrasound.Postnatal surgery corrected 3 cases,while 27 cases opted for pregnancy termination,and 4 cases resulted in intrauterine death.Echocardiographic features of the fetal IAA included a significantly smaller left ventricle compared with the right or negligible difference on the four-chamber view,a significantly smaller aorta than the pulmonary artery on the three-vessel view,and a lack of connection between the aorta and the descending aorta on the three-vessel-trachea and aortic arch views.The aortic arch appears less curved and more rigid,losing the normal"V"shape between the aorta,ductus arteriosus,and descending aorta.Color Doppler ultrasound showed no continuous blood flow signal at the interruption site,with reversed blood flow visible in the ductus arteriosus.Transmission electron microscopy of 7 IAA fetuses revealed numerous disorganized smooth muscle cells between the elastic membranes near the aortic arch interruption site,significantly increased in number compared with the proximal ascending aorta.The elastic membranes were thicker and more twisted near the interruption site.The interruption area lacked normal endothelial cells and lumen,with only remnants of necrotic endothelial cells,disorganized short and thick elastic membranes,and randomly arranged smooth muscle cells. Conclusion:Prenatal echocardiography is the primary diagnostic tool for fetal IAA.Post-surgical follow-up and autopsy help identify complications and disease characteristics,enhancing diagnostic accuracy.Some fetal IAA may evolve from AAD or CoA,with potential pathogenesis related to ischemia,hypoxia,and migration of ductal constrictive components.

OBJECTIVES:
Hypertrophic cardiomyopathy (HCM) frequently leads to myocardial ischemia and cardiac dysfunction. Even genotype-positive/phenotype-negative (G+/P-) individuals, carriers of pathogenic sarcomere gene mutations without left ventricular hypertrophy, remain at risk of progression to clinical HCM. This study aims to evaluate myocardial perfusion and contractile function in familial HCM patients and their first-degree relatives using myocardial contrast echocardiography (MCE) and velocity vector imaging (VVI), in order to identify early myocardial dysfunction and at-risk individuals within families.
METHODS:
Thirty-five genetically confirmed HCM patients with left ventricular hypertrophy were assigned to a G+/P+ group. A total of 30 first-degree relatives carrying sarcomere mutations but without echocardiographic evidence of left ventricular hypertrophy were assigned to a G+/P- group. A total of 38 age- and sex-matched gene-negative healthy family members served as controls. All participants underwent MCE and VVI assessments. Myocardial perfusion parameters, including peak intensity (PI), time to peak concentration (TP), and the ratio of declining intensity and declining time (dI/dT), as well as strain parameters including global longitudinal strain (GLS), global radial strain (GRS), and global circumferential strain (GCS) were recorded and analyzed for differences and correlations.
RESULTS:
Compared to both the G+/P- and normal control groups, the G+/P+ group had significantly lower PI, dI/dT, GLS, and GRS, along with significantly increased TP (all P<0.05). GLS and GRS were positively correlated with PI (r=0.629 and r=0.613, respectively; both P<0.01) and negatively correlated with TP (r=-0.597 and r=-0.571, respectively; both P<0.01). Compared to the normal control group, the G+/P- group showed a significant reduction in GLS (P<0.05), but no significant differences in GRS, GCS, PI, TP, or dI/dT (all P>0.05).
CONCLUSIONS
Myocardial contractile dysfunction in HCM patients is closely related to impaired perfusion. Even in the absence of wall hypertrophy, sarcomere mutation carriers show early signs of subclinical left ventricular dysfunction. MCE and VVI can quantitatively assess myocardial perfusion and function, offering valuable tools for early detection and risk stratification in HCM patients and their relatives.

Abstract
OBJECTIVE To conduct a quality markers(Q-Markers) study on the treatment of cough with Feire Zhike granules based on the “five principles” of Q-Markers, combined with mass spectrometry, network pharmacology and cobweb model. METHODS Identification of the main chemical components in Feire Zhike granules by liquid mass spectrometry. The TCMSP database was searched to collect the active ingredients and corresponding targets of 11 herbs in the prescription of Feire Zhike granules. The GeneCards database was also searched to collect genes encoding cough-related proteins, and a herb-component-target network map was constructed. Assigning effectiveness to active ingredients based on the number of target sites. Check the pharmacopoeia and literature to obtain the measurable components of each herb. Determine the monarchical, ministerial and adjuvant attribution of the original herbs in the compound formula based on the principle of compatibility. The literature and TCMSP database were searched to screen the original herb for specificity components. RESULTS A total of 43 chemical components in the Feire Zhike granules were identified to be “delivered” to the formulation based on UHPLC-Q-TOF-MS/MS. The 124 active compounds were obtained from the TCMSP database and acted on 120 targets, 93 of which were associated with coughing. There were 6 components in the pharmacopoeia that specify quantitative methods. A total of 26 endemic components were found in 11 herbs in the compound formula. In addition, the above components were ranked according to the compatibility rules of monarch and minister and the scoring rules of cobweb model. The top 10 components were wogonin, baicalein, licochalcone A, nobiletin, acacetin, hesperidin, liquiritin, tuberstemonine, β-sitosterol and galangin, respectively. CONCLUSION The above 10 components can be identified as Q-Markers of Feire Zhike granules.

Objective:To explore the method of ultrasonography for detecting the fetal umbilical vein diameter, blood flow volume and normalized volume blood flow and establish normal reference ranges with umbilical vein diameter, blood flow volume and normalized blood flow and Z-scores for umbilical vein diameter and blood volume flow.Methods:This was a prospective study on 907 normal fetuses in the Second Xiangya Hospital, Central South University and Women and Children Healthcare Hospital of Zhuzhou from March 2019 to December 2020. The umbilical vein diameter (Duv), umbilical vein blood flow volume (Quv) and normalized volume blood flow (nQ = Quv/estimated fetal weight) of the free loop of umbilical vein (FUV) and fetal intra-abdominal umbilical vein (IUV) were collected. And the mean values and 90% confidence intervals of Duv, Quv and nQ in two segments of umbilical veins at different gestational ages were calculated. Regression analysis of Duv, Quv and nQ were performed with gestational age (GA), and the parameters of umbilical vein in different segments were compared. Finally, with gestational age (GA) as the independent variable, Z-scores of the Duv and Quv were built.Results:The mean values and 90% confidence intervals of Duv, Quv, and nQ in 858 (94.6%) normal fetal umbilical veins were successfully obtained. The Duv, Quv of the FUV and IUV increased as pregnancy progressed. The Quadratic curve of Duv and Linear curve of Quv were of the highest fitnesses, respectively( r=0.951, 0.941, 0.986, 0.982; all P<0.001). While nQ increased with GA followed by a decreased trend, and the Quadratic curve was the highest fitting curve of nQ( r=0.610, 0.611; all P<0.001). Duv-FUV was greater than Duv-IUV( P<0.001), nQ-FUV was bigger than Quv-IUV( P=0.001), and he difference was not statistically significant between Quv-FUV and Quv-IUV( P=0.133). Z-scores models of Duv and Quv were successfully established, and all Z-scores were Gaussian distribution. Conclusions:The normal ranges and Z-scores of umbilical vein parameters are useful to improve the evaluation of placental circulation and provide a strong basis for the monitoring of fetus-related diseases and the evaluation of pregnancy prognosis. The choice of FUV or IUV umbilical vein to evaluate placental circulation may depend on the actual situation in clinical application.

PURPOSE: Details of patients hospitalized for asthma exacerbation in mainland China are lacking. To improve disease control and reduce economic burden, a large sample survey among this patient population is indispensable. This study aimed to investigate the clinical characteristics and outcomes of such patients.METHODS: A retrospective study was conducted on patients hospitalized for asthma exacerbation in 29 hospitals of 29 regions in mainland China during the period 2013 to 2014. Demographic features, pre-admission conditions, exacerbation details, and outcomes were summarized. Risk factors for exacerbation severity were analyzed.RESULTS: There were 3,240 asthmatic patients included in this study (57.7% females, 42.3% males). Only 28.0% used daily controller medications; 1,287 (39.7%) patients were not currently on inhaled corticosteroids. Acute upper airway infection was the most common trigger of exacerbation (42.3%). Patients with severe to life-threatening exacerbation tended to have a longer disease course, a smoking history, and had comorbidities such as hypertension, chronic obstructive pulmonary disease (COPD), and food allergy. The multivariate analysis showed that smoking history, comorbidities of hypertension, COPD, and food allergy were independent risk factors for more severe exacerbation. The number of patients hospitalized for asthma exacerbation varied with seasons, peaking in March and September. Eight patients died during the study period (mortality 0.25%).CONCLUSIONS: Despite enhanced education on asthma self-management in China during recent years, few patients were using daily controller medications before the onset of their exacerbation, indicating that more educational efforts and considerations are needed. The findings of this study may improve our understanding of hospital admission for asthma exacerbation in mainland China and provide evidence for decision-making.

Objective:To investigate the ultrasonographic features and prognosis of fetal vascular anomalies.Methods:Thirty-one fetuses with vascular anomalies diagnosed from June 2013 to August 2018 in Changsha Hospital for Maternal and Child Health Care were retrospectively analyzed. The location, size, shape, internal echo and blood flow distribution of the lesions were observed by ultrasound carefully, and the prognosis was followed up and analyzed.Results:Among the 31 cases of fetal vascular anomalies, 10 cases were comfirmed by autopsy after induced labor, and 21 cases were confirmed by postpartum local observation or surgery and pathology. Among them, there were 4 cases of Klippel-Trenaunay syndrome (including 1 case of Parkes-Weber syndrome), 3 cases of hemangioma, 1 case of primary congenital lymphedema and 23 cases of lymphangioma. Thirty-one cases showed lesions coincident with ultrasound localization and diagnosis, including 9 cases of head and neck lesions, 15 cases of trunk lesions, 1 case of upper limb lesion and 6 cases of lower limb lesions. The blood flow spectra of arteriovenous fistulas were found in 3 cases of fetal lesions and no obvious blood flow signals were found in 28 cases of fetal lesions.Conclusions:Prenatal ultrasound examination and follow-up play an important role in the diagnosis and prognostic prediction of fetal vascular diseases. The prognosis of fetal vascular diseases is closely related to the location, size, effect on the surrounding tissue and shunt volume of the lesion.

Objective:To develop Z-scores for the aortic arch in normal fetuses as a reference for fetuses with suspected coarctation of aorta(CoA).Methods:The aortic arch inner diameters of 610 normal fetuses and 59 CoA fetuses from May 2010 to March 2015 in the Second Xiangya Hospital of Central South University were measured at the long axis of the aortic arch view. Gestational age(GA), femur length(FL) as the independent variable, the aortic arch inner diameters as the dependent variable, Z-scores were created relating the aortic arch inner diameters to the GA and FL. Z-score=[ln(measured diameter)-ln(predicted diameter)]/root MSE. Z-scores of the CoA fetuses were calculated with the above regression, and compared with the Z-scores of the control group.Results:A simple linear regression model was the best description of the data in each case and correlations between FL and the aortic arch inner diameters were excellent ( P<0.001). There was no significant difference in Z-scores calculated with FL or GA as independent variables ( P>0.05). Z-scores of the control group was between -2 and + 2, Z-scores of the CoA group was significantly lower and below -2( P<0.001). Conclusions:Z-scores of fetal aortic arch are sensitive indicators of fetal coarctation, and are of clinical importance for the diagnosis and follow-up study of CoA.
