Objective To study the possibility of fetal cardiac rhabdomyoma diagnosed by ultrasonography,and the relationship between the fetal cardiac rhabdomyoma and family tuberous sclerosis. Methods High resolution ultrasonic equipment with fetal cardiac software was used. The main cross section of four chamber view was studied mainly. The location, the number of the tumor and the outflow tract of left and right ventricular cordis were scanned carefully, the maternal abdominal scan was performed as well. Results Five cases of fetal cardiac rhabdomyoma were found by routine prenatal ultrasonography, and were confirmed by autopsy. Among them, one case were associated with maternal tuberous sclerosis. Conclusions Fetal cardiac rhabdomyoma associated with tuberous sclerosis. Fetus with cardiac rhabdomyoma frequently die of cardiac failure; since the prognosis of the tuberous sclerosis with neural sclerosis was very poor, when the fetal cardiac rhabdomyoma was detected prenatally, the possibility of tuberous sclerosis should be considered, also relative examination must be performed to the mother to decrease the perinatal mortality.

Aim To investigate the effect of resveratrol (Res)on septic mice and LPS-insulted H9c2 cells,as well as its involved mechanisms.Methods By use of a mouse cecal ligation and puncture-induced septic model (CLP),the survival of septic mice was evalua-ted after resveratrol treatments.H9c2 cells were insul-ted by LPS and then treated with resveratrol,the mR-NA expressions of TNF-α,SIRT1 and other class III HDAC members were detected using RT-PCR and real-time PCR,Finally,the protein levels of nuclear p65, an important subunit of NF-κB,were measured in H9c2 cells using Western blot assay,to reveal the effect of resveratrol on LPS-induced nuclear transloca-tion of NF-κB.Results Compared with the control septic animals,intraperitoneal injection of resveratrol (1 or 5 mg·kg -1 ·d -1 )significantly increased the survival of septic mice.Furthermore,resveratrol signif-icantly increased mRNA expressions of SIRT1,SIRT2, SIRT6 and SIRT7 in LPS-insulted H9c2 cells.Res-veratrol also remarkably inhibited LPS-induced nuclear translocation of NF-κB.Conclusion An appropriate dose of resveratrol protects septic mouse hearts from the injury induced by LPS through the activation of SIRT family members and the inhibition of NF-κB pathway.

Objective To explore the influence of group psychotherapy on the alleviation of psychiatric nurses' compassion fatigue.Methods A total of 190 psychiatric nurses were investigated by compassion fatigue scale.Forty psychiatric nurses were selected to accept group psychotherapy for 10 times.The scores of compassion fatigue scale were compared before and after group psychotherapy and the influencing factors of therapeutic effect were analyzed.Results Thirty-eight psychiatric nurses had accomplished the intervention and follow-up.Compared with before group psychotherapy,the total scores of compassion fatigue scale and the scores of mental tension,passive behavior,doubtful ability and loss of morale among 6 dimensions after group psychotherapy were improved:(83.28±7.01) scores vs.(102.60±7.24) scores,(2.66±0.42) scores vs.(3.11±0.49) scores,(2.02±0.36) scores vs.(2.55±0.41) scores,(1.99±0.33)scores vs.(2.65±0.38) scores,(1.69±0.34) scores vs.(2.76±0.44) scores,and there were significant differences,P＜0.05.Regression analysis found that the work life,education level were correlated with the deduction rate of the total scores of compassion fatigue scale,t=2.858,3.099,P＜0.01.Conclusion Group psychotherapy can help psychiatric nurses to alleviate their compassion fatigue.

Objective To investigate the protective effects of astragalus preconditioning on the tolerance of ischemia time of mouse small intestine . Methods C57BL/6 mice were randomly divided into 5 groups (n = 7): sham operation group (Sham group),intestinal ischemia reperfusion group (IR group) and astragalus preconditioning group (ASIR group). IR group and ASIR group include 2 sub-groups respectively, specifically, 2 h reperfusion was performed 45 min (ASIR1) and 60 min (ASIR1) after blocking superior mesenteric artery. Intestinal terminal morphology was observed by light microscope after HE coloration . Serum levels of LPS , DAO and intestinal mucosa TNF-α were measured by ELISA. Intestinal Cyto C expression were detected by immunofluorescence. Results Astragalus preconditioning reduces Chiu′s score significantly. Expression of Cyto C was significantly down-regulated in astragalus preconditioning groups, and levels of LPS, DAO and TNF-αsignificantly decreased. The damages in IR2 group is obviously severe than in IR1, but there were no significant differences between this two groups after pretreatment with astragalus. Conclusion Astragalus preconditioning has obvious protective effects to intestinal ischemia reperfusion, and enhances the tolerance to longer time of ischemia.

ObjectiveTo study the prevalence rate of post-stroke depression (PSD) of the elderly in the community and analyze risk factors of them. MethodsThe elders of the age of 60 or over were sampled as subjects from a community. Zung (SDS) was used as screening instruments and Hamilton rating scale for depression (HRSD-24) as evaluating scales. The prevalence rate of PSD was surveyed. A structured questionnaire was used and physical examination was carried out. Risk factors measured included baseline information, daily habits, and history of main diseases (hypertension, coronary heart disease, diabetes mellitus, myocardial infarction, and so on). The relationship between risk factors and PSD was analyzed.ResultsThe prevalence of PSD was 9.5%. The risk factors for PSD were life quality and age. ConclusionPost-stroke depression disturbs elder's health and rehabilitation. The prevalence rate and harm of PSD are higher than depression without stroke.

Objective The clinical value of ifrst-trimester standard ultrasound views in screening for fetal structural abnormalities. Methods From September 2008 to March 2011, transabdominal sonographic screening by standard ultrasound views was performed in 3 134 viable singleton pregnancies during the ifrst trimester at Beijing Obstetrics and Gynecology Hospital. Used the following views:(1) Fetal proifle;(2) Neck sagittal;(3) Skull and brain;(4) Thorax;(5) Abdomen;(6) Bladder;(7) Upper limbs, and (8) Lower limbs. The women underwent 20-to 24-week and 28-to 32-week ultrasound examination if the anatomical survey was normal during the ifrst trimester. Follow-up was obtained by reviewing of the birth records from hospital charts. Results Sixteen prenatal abnormalities were detected at 11-to 13-week scan (including one case of encephalocele and meningoceles, one case of endothelial cushion defect and single umbilical artery, one case of ectopia cordis, gastroschisis, and spinal abnormalities, two cases of exencephaly, one case of anencephaly, one case of gastroschisis and lower limb malformation, two cases of omphalocele, one case of encephalocele, ectopia cordis, and gastroschisis, one case of single ventricle, one case of endothelial cushion defect, four cases of hyhrop). All of the 13 women decided on termination of pregnancy. Three suspected structural abnormalities (hydrops) detected at the ifrst-trimester scan were found as normal after birth. Seven cases were diagnosed at 20-to 24-week scan (including one case of dextrocardiac and double outlet right ventricle;two cases of endothelial cushion defects;one case of trisomy 21 with VSD;one case of omphalocele, one case of short ulna and radial with wrist distortion, and one case of club foot). One case of diaphragmatic hernia was detected at 32-week scan. Two cases (one case of cardiac defects and one case of ear deformity) were identified after birth. Of all the 3 134 fetuses, follow-up was obtained in 2 822 cases, 312 cases were excluded from the analysis because the outcome of their pregnancy could not be traced. Twenty-three fetuses with at least one major structural defect detected by prenatal ultrasonography were confirmed by follow-up. The sensitivity of the standard first-trimester ultrasound views was 56.5%(13/23), speciifcity was 99.9%(2 796/2 799), CR was 99.6%(2 812/2 822), and the false negative rate was 43.5%(10/23). Conclusions The standard views of the ifrst trimester are feasible and effective in screening the major fetal abnormalities including exencephaly, anencephaly, gastroschisis, omphalocele, ectopia cordis and single ventricle. However, ultrasound screening in early pregnancy still has some limitations, continuous scanning in different stages of pregnancy is necessary.

Objective To study the sonographic features of papillary thyroid carcinoma (PTC) associated with cervical lymph nodes metastasis for early diagnosis and prediction of the invaded cervical lymph nodes. Methods The sonographic features of 170 patients with pathologically confirmed PTC in First Afifliated Hospital of Harbin Medical University between 2011 and 2013 were retrospectively reviewed. There were 59 cases with neck lymph nodes metastases and 111 cases without neck lymph nodes metastases. Receiver operating characteristic (ROC) curve was aaplied to analyze the cut-off values of resistance index (RI) and peak systolic velocity (PSV) for judging the presence or absence of cercical lymph node metastasis. The Chi-square test and rank sum test were used to compare the different sonographic features between each group. The Logistic regression analysis was used to obtain the relevant factors of PTCs with cervical lymph node metastasis. Results ROC curve analysis showed that the cut-off values of RI and PSV were 0.735,13.95 cm/s. The primary tumor diameter, the existence of halo, the involvement of thyroid upper pole, the microcalciifcation, the blood suply classiifcation and the RI, PSV were statistically signiifcantly different between PTCs with and without cervical lymph node metastasis, whereas no statistical signiifcance was detected between the primary tumor echo pattern, boundary and the longitudinal/transveral ratio between the metastatic and nonmetastatic group. Logistic regression analysis showed that the PTC primary tumor diameter and PSV were independent factors coorelated with cervical lymph node metastasis. Conclusion Some sonographic features of PTC are closely correlated with lymph nodes metastasis, which are valuable in predicting the cervical lymph nodes metastasis in patients with PTC pre-operatively.

Objective To investigate the relationship between inflammatory factors, coronary artery dilation, and their clinical significance. Methods The cases undergone coronary angiography in our hospital last year were collected and divided into three groups: the first one included 11 patients whose angiography showed coronary artery dilation, the second group included 35 cases of atherosclerosis, and the third includes 24 cases with normal angiography. sES, MMP9 and TIMP1 were measured by ELISA method. Results Patients with coronary artery dilation were found to have significantly higher sES and MMP-9 level in comparison with atherosclerosis group and normal group[(153.7?152.7)ng/L,(90.1?54.2)ng/L,(76.5?37.2)ng/L, respectively](P
