Purpose To investigate the diagnostic value of fetal echocardiography in total anomalous pulmonary venous connection (TAPVC),and to analyze the reasons ofmisdiagnosis so as to improve accuracy of prenatal diagnosis.Materials and Methods The prenatal echocardiographic data of 24 cases of TAPVC confirmed by postnatal echocardiography and prenatal MRI from October 2001 to December 2015 in Children's Hospital Affiliated to Nanjing Medical University and Shanghai Children's Medical Center Affiliated to Shanghai Jiaotong University School of Medicine were retrospectively analyzed.Results In 24 cases,there were 14 fetuses of supracardiac type,7 cases of intracardiac type,2 cases of infracardiac type,and 1 case of mixed type.15 fetuses had TAPVC only,whereas 9 cases were associated with other cardiovascular anomalies,most commonly including bilateral right atria,single atrium,single ventricle,common atrioventricular valve and pulmonary stenosis.On 4-chamber views,the common sonographic sign was absent of pulmonary venous return to the left atrium in 24 cases (100.0％),and the presence of venous confluence between left atrium and descending aorta was observed in 22 cases (91.7％).In all 24 cases,1 case was missed diagnosis,and 3 cases were misdiagnosed as persistent left superior vena cava,common pulmonary vein atresia and patent left atrial cardinal vein.Conclusion TAPVC can be accurately diagnosed by fetal echocardiography,but it is prone to be misdiagnosed.

Objective Analyse the causes,diagnosis and treatment for delayed hemorrhage after distal radical gastrectomy.Methods Retrospective study on 45 patients combined with intro-abdominal hemorrhage after distal radical gastrectomy from January 2008 to June 2013.Results Thirteen patients combined with delayed hemorrhage in these 45 patients,all of 13 patients had intro-abdominal hemorrhage in 1week to 4 weeks after operation.And 5 of the 13 patiens were intermittent intro-abdominal hemorrhage 1 week after operation,these patients were demonstrated the blood come from gastroduodenal artery pseudoaneurysm fracture by CT and DSA examine,and they were cured by interventional embolization.Other 8 patients were marginal ulcer hemorrhage diagnosed by gastroscope,and they stoped bleeding with the help of gastroscope.Conclusions The causes of delayed hemorrhage after distal radical gastrectomy were complicated,and CT,DSA and endoscope can use for diagnosis.What was more,interventional embolization and endoscope were helpful for curing the intro-abdominal hemorrhage,avoiding re-operation.

Purpose To explore the correlation between fetal cardiac function and interventricular septal thickness in fetuses of gestational diabetes mellitus (GDM) mothers. Materials and Methods Thirty-nine GDM mothers were involved in the study and divided into group MH (fetuses of GDM mothers with interventricular septal hypertrophy) and group NMH (fetuses of GDM mothers with normal interventricular septal thickness). Ultrasonic cardiogram was performed for both groups to assess such variables as interventricular septum thickness at end diastole (IVSd), left ventricular ejection fraction (LVEF), left ventricular fraction shortening (LVFS), right ventricular fraction shortening (RVFS), the ratio of E and A of mitral flow (E/AMV), the ratio of E and A of tricuspid flow (E/ATV), peak velocity of aortic valve (VPAO), peak velocity of pulmonary valve (VPPA) and myocardial performance index (MPI). The results were further compared with those of control group. Results The VPAO, VPPA, LVEF and LVFS in group NMH were significantly higher than those in control group (P<0.05). The VPAO, VPPA, LVEF, LVFS and RVFS in group MH were significantly higher than those in control group whilst the E/AMV and E/ATV significantly lower than those in control group (P<0.05). The LVEF, LVFS and RVFS in group MH were significantly higher than those in group NMH whilst the E/AMV and E/ATV significantly lower (P<0.05). MPI in group MH was significantly higher than that in group NMH (P<0.05), whilst both were significantly higher than that in control group (P<0.05). The LVEF, LVFS, RVFS, VPAO and VPPA were positively correlated with IVSd (r=0.48, 0.51, 0.45, 0.30, 0.30;P<0.05). Conclusion Cardiac function in fetuses of GDM mothers may be associated with interventricular septal thickness.

Objective To find out the risk factors of postoperative low cardiac output syndrome(LCOS) of patients undergoing cardiac valvular surgery in ICU in order to provide basic for prevention and control measures.Methods Ninety-six valve replacement patients with valvular heart disease were enrolled as our subjects and they were hospitalized in ICU of the First People's hospital of Yichang from Jan.2008 to May.2013.The patients postoperative LCOS (Dopamine ＞ 10 μg/(kg · min)) were served as observation group (n =41),and the other were control groups(n =55).All data of the patients were recorded.Non-conditions Logistic regressions analysis were adopted to analyze the independent risk factors which resulted in LCOS undergoing cardiac valvular surgery.Results Of 96 patients undergoing cardiac vavular surgery,41cases (42.7％) had postoperative LCOS.Single factor analysis showed that hepatomegaly (P =0.007),course of diseases ≥ 15 years (P =0.042),cardiopulmonary bypass ≥ 120 min (x2 =3.937,P =0.047),pre-operative cardiac function ≥ Ⅲ degree (P =0.003) were the independent risk factors of postoperative LCOS undergoing cardiac valvular surgery.The Logistic multi factor regression analysis showed that the independent risk factors of postoperative LCOS undergoing cardiac valvular surgery included course of diseases ≥ 15 years (OR =2.825,95％ CI =(1.015-7.861)),Pre-operative cardiac function ≥ Ⅲ degree (OR =7.306,95％ CI =(2.050-26.035),P=0.002).Conclusion Course of diseases ≥15 years and Pre-operative cardiac function≥ Ⅲ-Ⅳ degree are the independent risk factors of LCOS undergoing cardiac valvular surgery.

Panax notoginseng (BurK.) F.H.Chen is a traditional Chinese medicinal material with a time-honored history of cultivation.There are a series of problems,such as high pesticide residues,serious disease and pest,and continuous cropping obstacles in the process of the cultivation of notoginseng.Pollution-free cultivation is an effective strategy for the sustainable development of notoginseng industry.We herein summarized three points of the pollution-free cultivation of notoginseng in this review.The standard of lands suitable for the cultivation of notoginseng was established on the basis of the analysis of medicinal plants around global producing areas.The integrated measures of soil improvement were put forward by cfficient rotation and soil disinfection with new varieties breeding combined with the management of water,light and fertilization,and the safe and low-toxic methods of disease and pest control.Additionally,the mode of wild tending should be carried out when the marker-assisted breeding of new varieties was developed,and the platform of comprehensive disease and pest control was founded.Above-mentioned points can effectively perfect and optimize the pollution-free cultivation of notoginseng and promote sustainable development of notoginseng industry.

Objective To analyze the level of cardiac troponin I (cTnI) in children with left-to-right shunt congenital heart disease (CHD). Methods In this study, 146 children with secundum atrial septal (ASD) defect, 132 children with ventricular septal defect (VSD) and 300 healthy children were recruited. The levels of cTnI and N-terminal pro-brain natriuretic peptide (NT-proBNP) were measured and their correlation with clinical data was analyzed. Results The serum cTnI and NT-proBNP levels in both ASD and VSD patients were signiifcantly higher than those in normal children (H=3.89 and 5.27, P<0.01). The serum cTnI and NT-proBNP levels in VSD patients were signiifcantly higher than those in ASD patients (P<0.05). The ratio of pulmonary to systemic arterial pressure (Pp/Ps), pulmonary vascular resistance index (PVRI) and standardized left ventricular end diastolic volume in VSD patients were signiifcantly higher than those in ASD patients (P<0.05). Multiple regression analysis showed that Pp/Ps was signiifcantly correlated with cTnI in VSD patients. (β=0.81, SE=0.03, P=0.000). Conclusions Signiifcant volume and pressure overload due to a left-to-right shunt induce myocardial injury and could lead to irreversible myocardial remodeling in children with CHD. The serum cTnI level is a sensitive biomarker for myocardial damage in VSD patients.

The purpose of education is to cultivate talents who can master the ability of self-learning lifelong. With the rapid development of multimedia technology, the knowledge carrier represented by micro curriculum plays a very important role in improving students' self-learning ability. In traditional Chinese medicine college, due to the short of time, weak learning foundation, the ability of self-learning is hard to improve in the modern medical courses such as biochemistry. This is not conducive to the cultivation of modern talents of Chinese medicine. In this paper, we chose the biochemistry teaching in TCM college as an example, and discuss how we can make the application of micro courses reasonably in the teaching process. This study was regarded as a starting to improve the students' self-learning ability effectively.
