Objective To discuss the value of contrast-enhanced ultrasound and color Doppler in diagnosing esoph-ageal varices( EV) among patients suffering from portal hypertension. Methods The control group consisted of twenty nine patients without EV. Sixty patients with EV diagnosed by endoscopy were divided into two groups equal in number according to grade of EV. One being mild,the other was moderate to severe. All patients underwent color Doppler flow imaging and contrast-enhanced ultrasound, and the dynamic angiography data were collected. Time-in-tensity curves were drawn by software. The quantitative parameters including arrival time of hepatic artery ( HAAT) ,hepatic vein ( HVAT) and portal vein ( PVAT) ,damping index ( DI) of hepatic vein and portal vein ve-locity( PVV) were compared. Results The difference of PV-HV, PV-HA, PVV, DI showed statistically signifi-cant among the three groups(F=72.63,14.97,6.71,13.74,P<0.01). A comparison of the control and moderate to severe group among the above four parameters was statistically significant (P<0.01). PV-HV, PV-HA, DI in moderate to severe group showed statistically significant compared with mild group (P<0.01),however there exis-ted no significant difference grouping PVV between the two groups. Mild group contrasted to the control group,the differences of PV-HA were statistically significant (P<0.01), whereas PV-HV, DI, PVV displayed no significant difference. Conclusion Contrast-enhanced ultrasound and color Doppler are helpful in diagnosing EV,which is ex-pected to become a new noninvasive method.

BACKGROUND/AIMS: In recent years, greater assessment accuracy after transjugular intrahepatic portosystemic shunt (TIPS) to ascertain prognosis has become important in decompensated cirrhosis due to portal hypertension. The aim of this study was to assess the ratio of the portal pressure gradient (PPG) pre-TIPS (pre-PPG) to albumin (PPA), which influence ascites formation in cirrhotic patients in the 6-months after TIPS placement, and is a metric introduced in our study. METHODS: This was a retrospective cohort study of 58 patients with decompensated cirrhosis admitted to an academic hospital for the purpose of TIPS placement. We collected the following data: demographics, laboratory measures, and PPG during the TIPS procedure. Then we analyzed the association between the above data and ascites formation post-TIPS in cirrhosis patients. RESULTS: Twenty-two patients with ascites and 28 without ascites were evaluated. Univariate and binary logistic regression analysis were adjusted for the following variables: to determine prognosis; Child-Pugh scores, lymphocyte count, platelet count, hemoglobin level, albumin level and pre-PPG or PPA. The outcome showed that PPA was better than pre-PPG and albumin for predicting ascites according to area under receiver operating characteristic curves and a statistical model that also showed PPA’s influence 6-months post-TIPS. CONCLUSIONS: The combined measurement of pre-PPG and albumin, defined as PPA, may provide a better way to predict post-TIPS ascites in decompensated cirrhosis, which underlines the need for a large clinical trial in the future.

Objective:To explore the method of sequential sector scan with 2D ultrasound through oral fissure (SSTOF) and its utilization in the cleft palate screening.Methods:Based on features of oral anatomy and ultrasonic beam, SSTOF was designed to screen cleft palate and the accuracy had been verified using specimens of aborted fetuses. This study recruited 7 154 women with singleton pregnancy who were screened for fetal malformations during 20-28 gestational weeks in the First Affiliated Hospital of Anhui Medical University from May 2020 to October 2020. In medical addition to routine screening, these subjects also underwent SSTOF to further verify its feasibility and imaging performance. Follow-up was performed by telephone and medical record review.Results:Clear images of the upper palate were acquired in five specimens of induced fetuses using SSTOF. Except for 56 cases lost to follow-up, a total of 7 098 fetuses were finally enrolled, of which 6 885 acquired satisfactory images using SSTOF, 213 did not due to inappropriate position, with a success image rate of 97%. SSTOF found cleft palate in 31cases, which were all confirmed after birth or induction, noting an accuracy rate of 100%.Conclusion:Sequential sector scan through oral fissure has a high clinical value on cleft palate screening in the second trimester with advantages of clear image, easy operation, and access to section views.

Objective:To investigate the prevalence of depression and to analyze its determinants among centenarians in Hainan.Methods:A cross-sectional study on centenarians was conducted in Hainan from June 2014 to December 2016.A total of 910 centenarians, including 166 males and 744 females, were interviewed in their domiciles by trained investigators.A 15-item Geriatric Depression Scale(GDS-15)was used to assess depression for centenarians, and general sociodemographic details, sleep quality, cognitive function, activities of daily living, and lifestyles were recorded.Multivariate logistic regression analysis was used to determine major related factors for depression in centenarians.Results:Of the 910 centenarians, 292 were regarded as depressed and the prevalence was 32.1%.Univariate analysis showed that there were significant differences in gender, education, marital status, self-reported health, incontinence, dietary habits, sleep quality, activities of daily living, cognitive function, outdoor activities, watching TV, and social engagement between subjects with and without depression( P<0.05). Multivariate logistic regression analysis showed that living conditions, self-reported health, activities of daily living, and sleep quality were independent related factors for depression in centenarians( P<0.05). Among the above related factors, living with families( OR=0.50, P=0.026)and good sleep quality( OR=0.67, P=0.010)were protective factors for depression, whereas poor self-reported health( OR=3.34, P<0.001)and disability( OR=2.37, P=0.002)were risk factors for depression in centenarians. Conclusions:Living conditions, self-reported health, activities of daily living, and sleep quality were independently correlated with depression in Hainan centenarians.This study provides empirical evidence for depression interventions and mental health improvement in centenarians.

Objective:
To investigate the value of left ventricular global longitudinal strain( LVGLS) in predicting early chemotherapy related cardiotoxicity in breast cancer patients after chemotherapy.
Methods :
Eighty-six breast cancer patients were enrolled in this study and received 6 cycles of doxorubicin + cyclophosphamide.Conventional echocardiography parameters were measured before chemotherapy ( T0 ) ,immediately after chemotherapy ( T1 ) ,6 months(T2) and 12 months after chemotherapy ( T3 ) . LVGLS was obtained by 2D speck tracing imaging (2DSTI) ,and the relative change of LVGLS( △LVGLS) was calculated at T1.With the occurrence of cardiotoxicity as
the clinical outcome,receiver operating characteristic ( ROC) curve was plotted.The parameters were analyzed at T1 to evaluate the value of △LVGLS in predicting cardiotoxicity.
Results:
① Although the change in LVEF was not different between T0 and T1 (P >0. 05) ,LVEF decreased significantly at T2 and T3 (P <0. 05) . ② Compared with T0,LVGLS decreased at T1,which was further damaged at T2 and T3 (P<0. 05) . ③ Seven patients (8. 1% ) developed chemotherapy-related cardiotoxicity.LVGLS and △LVGLS were correlated with cardiotoxicity at T1 stage ,and △LVGLS was more significant ( r = 0. 64,P <0. 001 ) . ROC curve analysis showed that a △LVGLS >12% at T1 predicted cardiotoxicity,with sensitivity of 92. 2% ,specificity of 76% ,and area under the curve was 0. 88.
Conclusion
The LVGLS decreased earlier than LVEF in breast cancer patients after doxorubicin treatment. △LVGLS >12% is a good predictor of cardiotoxicity in patients with breast cancer.
