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 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 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 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.

Objective:To investigate the characteristics of event-related potentials(ERPs)P300 in the development of attention cognitive function of school-age children.Methods:A total of 180 school-age children were divided into 3 groups according to their ages (7-8 years old group with 48 cases, 9-10 years old group with 44 cases and 11-12 years old group with 48 cases). All of the participants completed an Oddball task, and their behavioral data, P3a and P3b components of ERPs were analyzed by SPSS 21.0.Results:(1)The differences of hit numbers(49(47.25, 50), 50(49, 50), 50(50, 50) ), correct reaction time((533.37±56.94) ms, (486.91±61.12) ms, (411.55±51.97) ms), and Omission errors (2(1, 4), 2(1, 3), 1(0, 2) ) among the three groups were statistically significant( F/χ 2=20.635, 54.477, 13.169, all P<0.01). (2)There was a main effect of age( F=3.884, P=0.023) and an interaction effect between age and condition( F=3.314, P=0.038) on the amplitude of P3a, while the main effect of condition was not significant( F=0.111, P=0.740). The amplitude of P3a component in 11-12 years old group ((11.02±6.00)μV) was significantly larger than that of 7-8 years old group ((7.36±4.48)μV) and 9-10 years old group ((7.76±5.17)μV, both P<0.05). However, there was no significant interaction effect between age and condition on P3a latency, P3b amplitude and latency ( P>0.05). Conclusion:P3a may be a sensitive indicator of cognitive function in school-age children, and the age of 11-12 years old is a sensitive period for the development of children's attention orientation and selection ability, which may be related to the development of brain network.

Objective:To explore the association between platelet/lymphocyte ratio (PLR) and frequent peritoneal dialysis (PD) - associated peritonitis (PDAP) in PD patients.Methods:The data of PD patients with PDAP from Guizhou Provincial People's Hospital between January 2015 and June 2019 were analyzed retrospectively. The patients were divided into mono group (only once PDAP occurred in one year) and frequent group (2 or more PDAP occurred in one year) according to the frequency of PDAP. The demographic data including gender, age, height and weight, the clinical data including blood pressure, duration of PD, causes of peritonitis, the laboratory data at the first time of PDAP and the prognosis of PDAP were compared between two groups. Logistic regression analysis method was applied to analyze the relationship between PLR and frequent PDAP. The predictive power of PLR was evaluated by receiver operating characteristic curve (ROC).Results:A total of 78 PD patients with PDAP were enrolled, including 53 males and 25 females, with average age of 45.2 years. The total person-year was 765.1 person-years and the incidence of peritonitis was 0.10 case/person-year during the median follow-up of 16 months. All patients were divided into two groups: 53 patients in mono group and 25 patients in frequent group. Compared with mono group, the patients in frequent group had lower body mass index, longer dialysis duration, higher systolic blood pressure level, higher PLR level, lower uric acid level, and higher rate of drug-resistant bacteria in peritoneal effusion (all P<0.05). The extubation rate of the frequent group was 44.0%(11/25), which was significantly higher than that [15.1%(8/53)] of mono group ( P<0.05). Multivariate logistic regression analysis showed that higher PLR level was an independent related factor for frequent PDAP( OR=1.006, 95% CI 1.002-1.010, P=0.003), and the area under the ROC curve of PLR was 0.783(95% CI 0.663-0.904, P<0.001). Conclusions:High PLR level is an independent related factor of frequent PDAP for PD patients, and PLR can be a potential predictor of frequent PDAP.

Objective To investigate the risk factors of acute kidney injury following coronary artery bypass graft(CABG).Methods Twenty-six patients suffering from acute kidney injury following CABG as the patient group and 59 individuals without impairment of renal function as the control from January 2008 to September 2012 in the First People's Hospital of Yichang according to a retrospective case-control study and nonconditional multivariable Logistic regression analysis method..Results Among the 85 patients undergoing CABG,26 suffered acute kidney injury following CABG with a morbidity rate of 30.59％.Identified risk factors for acute kidney injury following CABG included pre-operative mederale-sever cardiac insufficiency,prolonged mechanical ventilation,prolonged stay in ICU and anemia before surgery.The identified independent risk factor of acute kidney injury following CABG was pre-operative mederale-sever cardiac insufficiency (OR =3.206,95％ CI:1.067-9.631).Condusion Pre-operative mederale-sever cardiac insufficiency was an independent risk factor of acute kidney injury following CABG.

Objective To investigate the expression and the effects of tissue inhibitor of metalloproteinases-1 (TIMP-1) on lungs of rats with sepsis.Methods Forty Sprague-Dawley (SD) rats were randomly divided into two groups,namely sham group (n =8) and sepsis model group (n =32).The rats of model group were modeled by cecal ligation and puncture (CLP),and were further divided into four subgroups as per the time after modeling,namely 6 h (n =8),12 h (n =8),24 h (n =8),48 h (n =8)subgroups.Blood and lung samples were taken 6 h,12 h,24 h and 48 h after modeling.The histological changes in lungs of the rats were observed under light microscope.Expressions of TIMP-1 mRNA,Bax mRNA and Bcl-2 mRNA in lungs were measured by RT-PCR.The immunohistochemistry was used to label the CD18 in lungs during different phases of sepsis.The data were processed by t test.Results Compared with sham group,the lung tissues of rats in model group were injured to a certain extent after CLP.The expression of TIMP-1 mRNA and the number of CD18 positive cells increased at the same time (P ＜ 0.01),and peaked 24 hours later (P ＜ 0.01).While the expression of Bax mRNA in model group decreased markedly 12-48 hours after modeling (P ＜ 0.01-0.05),and reached minimum 48 hours later (P ＜ 0.01).The expression of Bcl-2 mRNA in model group changed unnoticeable.The positive correlation between variations in number of CD18 positive cells and expression of TIMP-1 mRNA was found in model group (r =0.426,P ＜ 0.01).Conclusions The increase in expression of TIMP-1 mRNA in lungs is closely associated with the lung injury of sepsis.The mechanism of lung injury is likely attributed to the preservation of inflammatory cells from apoptosis,and the persistent inflammation response causes tissue damage,leading to organ dysfunction.

Objective The study was to find the application effect of high quality nursing service in perioperative treatment of patients with coronary heart disease.Methods Eighty patients were randomly divided into the comfort nursing group and the routine nursing group with 40 patients in each group.The comfort nursing group was given high quality nursing service,and the routine nursing group received the conventional care.The effect in two groups was compared after rehabilitation.The statistical software of SPSS 17.0 was used to analyze the data.Results The degree of anxiety was lower,the number of patients with complication was less,the degree of satisfaction was higher and the time in hospital was less in the comfort nursing group.Conclusions The comfortable nursing care should be used in peri-operative treatment of coronary heart disease,which can make patients keep the best mental state to accept and cooperate with the surgical treatment.It also can improve the care quality and patients' satisfaction degree and shorten the hospital stay.
