Objective To assess the left ventricular(LV)segmental function by velocity vector imaging(VVI)in uremic patients with diffferent quantity of parathyroid hormone(PTH).Methods Sixty patients with uremia were divided into 2 groups according to the value of PTH:group A with PTH less than 3 times of upper normal limit,group B with PTH more than 3 times of upper normal limit.Normal control group was 30 healthy subj ects.All people were evaluated by VVI.The parameters,including the longitudinal systolic strain rate(SSR),diastolic strain rate(DSR),were analysed among the three groups.Results Compared with normal group,in group A and B,SSR,DSR in all segments were lower.Compared with group A,in group B,DSR were all significantly lower(P＜0.05),SSR in apex of laternal wall,medium of anterior septum wall,posterior wall,medium and apex of posterior septum wall and superior wall,base,medium and apex of anterior wall were significantly lower(P＜0.05).There was no statistically significant difference of left ventricular ejection fraction between the two groups(P＞0.05).Conclusions VVI is a viable objective tool to quantitatively assess LV segmental function damaged by different quantity of PTH.

Objective To investigate the clinical outcome and prenatal diagnosis feasibility of fetal congenital cardiac diventiculum.Methods The data of 12 fetuses with congenital cardiac diventiculum were retrospectively reviewed.The prenatal and postnatal medical records,including the characteristics of diverticulum,presence of abnormalities,karyotype and the outcomes of each pregnancy were collected.Results The overall incidence of cardiac diventiculum was 0.03％ (12/40 564) and the rate of incidence between left and right ventricle was 2 ∶ 1.Mean size of diventiculum was (69.75 ± 28.73)mm2,mean diameter of the diventiculum neck was (3.58 ± 0.80) mm and mean thickness of diventiculum wall was (1.54± 0.29)mm.Seven cases (58.4％) as an isolated malformation,5 cases (41.6％) combined with cardiac defect and extracardiac abnormalities,2 cases (16.7 ％) with chromosomal abnormalities.Five cases underwent termination of pregnancy,1 case died in uterus and 6 cases were born live.The mean follow-up periods was (62.33±-36.52)month.Of the 6 follow-up cases,4 cases (66.7％) remained asymptomatic,one case underwent drug therapy because of arrhythmia and one case combined with VSD underwent operation.Conclusions Echocardiography could be an useful tool to demonstrate and monitor congenital cardiac diventiculum prenatally and postnatally.The outcome of cardiac diventiculum depends on the size,progression,and the combined abnormalities and complications.

OBJECTIVE: To evaluate the cardiac function of fetuses with intrauterine growth retardation (IUGR) by using tissue Doppler imaging (TDI). METHODS: Peak velocity in early (E) and late (A) diastole were measured by pulsed-wave Doppler, and the peak annular velocities in systole (S'), early (E') and late (A') diastole were measured by TDI. Isovolumetric contraction time (ICT), ejection time (ET), isovolumetric relaxation time (IRT) were recorded. The ratios E/A, E'/A', E/E', E/(E'× S') and myocardial performance index (MPI) were calculated. RESULTS: Compared with the control group, E', A', S' and E'/A' were obviously lower (P<0.05) while E/E', E/(E'× S') and MPI were obviously higher (P<0.05) in the IUGR group; although E, A and E/A were slight lower in the IUGR group, the change was not significant (P>0.05). CONCLUSION Both diastolic and systolic heart function were jeopardized in IUGR fetuses.

Objective To summarize the clinical characteristics of adult patients with residual yolk duct,and to explore the diagnosis and treatment strategy of residual vitelline duct in adults.Methods A retrospective analysis on 11 adult cases with residual vitelline duct in our hospital between June 2012 and May 2017 was carried out.Results 8 cases were males,3 cases were females,and median age was 50 years (18-57 y).2 cases were vitelline cyst,9 cases were Meckel diverticulum.2 cases were with ectopic tissue,3 cases with ulcer bleeding,1 case with secondary intra-abdominal hernia and intestinal obstruction,2 cases with secondary infection.The pathological diagnosis of Meckel diverticulum was consistent with preoperative diagnosis.There were no major postoperative complications.The patients were followed up from 6 months to 2 years.Conclusion Most of the residual vitelline duct in adults are Meckel diverticulum and vitelline duct cyst.Resection of residual vitelline duct is the main treatment method.

Objective To summarize the clinical characteristics of hepatic lymphoepithelioma-like carcinoma,and to explore the diagnosis and treatment strategies of hepatic lymphoepithelioma-like carcinoma.Methods A retrospectively analysis on 13 patients with liver lymphoepithelioma-like carcinoma in Union Hospital,Tongji Medical College,Huazhong University of Science and Technology,between March 2005 and May 2019 were carried out.Results 8 cases were male,5 were female,median age was 45years (27 to 68 y).There were 8 cases of intrahepatic cholangiocytic lymphoepithelioma-like carcinoma,4cases of hepatocytic lymphoepithelioma-like carcinoma,and 1 case of mixed hepatocytic and cholangiocytic lymphoepithelioma-like carcinoma.All patients received partial hepatectomy and postoperative comprehensive treatment.The patients were followed from 6 months to 7 years.Only one patient died,and the other patients were all in a tumor-free state.Conclusion Primary hepatic lymphoepithelioma-like carcinoma is a rare liver cancer.It is confirmed mainly by pathological examination and immunohistochemistry.With surgery as the main treatment,prognosis is usually fair.

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.

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.

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.
