Objective To study the anti-neuroglioma effect of methyl-mercuric chloride(MMC) by observing the morphological changes of apoptotic neuroglioma cells induced with MMC in rats with brain neuroglioma.Methods The rat models of neuroglioma were established,and divided into two groups.The rats in experimental group were lavaged with MMC 1 week after injected with C6 glioma cells,10 mg?kg-1every day,the rats in control group were treated with sodium chloride at the same dose.24 d after inoculation all rats were sacrificed except natural death,the brain tissues were obtained,and the pathohistological changes were observed under light microscope and transmission electron microscope.Results The macropathological result showed that the tumor volume in experimental group was smaller than that in control group.Under light microscope,in experimental group the growth density of C6 ghioma cells was lower than that in control group,and the apoptotic cells with smaller volume and karyopyknosis were found.The result of transmission electron microscope showed that in experimental group,the glioma cells had some changes such as karyopyknosis,chromoplasm margination,nuclear fragmentation and vacuolar degeneration and so on.Conclusion MMC has inhibitory effect on the proliferation of C6 glioma in rats in vivo,its mechanism may be related to inducing the apoptosis of neuroglioma cells.

For more than 40 years primary hepatocytes culture technique has been utilized extensively for assessing effects of drug on metabolizing enzymes (especially cytochromes P450), drug metabolism, drug-drug interactions, and the mechanisms of cytotoxicity and genotoxicity. Human derived primary hepatocytes reserve the metabolism function and enzyme activity of liver. Therefore, this technique has been widely used as a reliable and efficient tool in the drug and xenobiotics evaluation and screen in vitro. This review focuses on primary culture technique of hepatocytes and its application in drug metabolism and toxicology research and evaluation.

Objective:The significant role of long non-coding RNAs (lncRNAs) in early diagnosis and predicting prognosis has been recognized in various cancers recently.However,the prognostic value of HOXA transcript at the distal tip (HOTTIP),a vital lncRNA in tumorigenesis,remains unclear.In this study,we evaluated its prognostic value by analyzing the correlation of HOTTIP expression with overall survival (OS),lymph node metastasis (LNM) and distant metastasis (DM) in different cancer types by meta-analysis.Methods:We performed a systematic search in PUBMED,MEDLINE,Web of Science and Cochrane Library update to November of 2016.A total of 604 patients from 6 studies were included in final analysis and went through a quantitative meta-analysis by Review manager 5.3.Results:We demonstrated that high expression of HOTTIP had a significant correlation with poor OS (hazard ratio [HR] =2.37,95％ confidence interval [CI] =1.81-3.10,p＜0.001),high LNM rate (odds ratio [OR]=2.29,95％CI=1.54-3.40,p＜0.001) as well as more DM occurrence (OR=3.30,95％CI=1.78-6.12,p＜0.001).Conclusion:Our results indicated that long non-coding RNA HOTTIP may serve as a potential prognostic biomarker in cancer progression.

Objective To explore the effect of Bailing capsule on epithelial-mesenchymal transition( EMT) in rats with adenine-in-duced tubulointerstitial fibrosis. Methods Tubulointerstitial fibrosis animal models were established and SD rats were divided into mo-del group ( n = 30), treatment group ( n = 30) and control group( n = 30), randomly. Experimental rats were harvested at 7 w, 12 w,17 w after onset of experiment and functional evaluations were performed. Histology, immunohistology were examined to investigateboth histolopathology changes and the expression of bone morphogenic protein-7 (BMP-7), transforming growth factor-β1 (TGF-β1 )and a-smooth muscle actin (α-SMA) in kidneys at three time points mentioned above, respectively. Results Compared with controlgroup, 24 h urinary protein in model group lost increasingly and significantly difference appeared at three time points relative to controlgroup ( P ＜ 0.01 ). Urinary NAG in model group was markedly higher than that in control group from 7 w after onset (P ＜ 0.01 ) andwas increasingly raised at 12 w and 17 w (P＜0.01). The value of blood BUN and Cr in model group increased at 7 w (P＞0.05) rel-ative to control group. There was significant difference at 12 w and 17.w (P ＜ 0.01 ). Histologically, kidneys in model group, at 7 w,exhibited tubular casts and gently tubular dilation, granuloma in cortex, mononuclear cells infiltration in tubulointerstitial areas, andmild interstitial fibrosis. At 12 w, the degree of tubular injury and tubulointerstitial fibrosis gradually aggravated. Up to 17 w, diffusetubular dilation or atrophy was observed and focal tubules disappear. Diffuse interstitial fibrosis was exhibited. In normal kidneys, im-munohistochemistry suggested that the light expression of BMP-7 was detected in proximal renal tubular epithelial cells and marked ex-pression was identified in distal tubule, collecting duct, and renal tubular epithelial in junction area between cortex and medulla. How-ever, the expression of BMP-7 in kidneys of model group significantly decreased with increasing tubulointerstitial fibrosis and was nega-tive correlation with the expression of TGF-β1(r = -0. 981 P＜0.01) and α-SMA (r= -0.975 P＜0.01). Bailing capsule ad-ministration protected the expression of BMP-7 and reduced TGF-β1 and α-SMA expression before 12 w(P＜ 0.01 ). Conclusions Ourstudy shows an anti-fibrotic reno-protective function of Bailing capsule in rats with tubulointerstitial fibrosis via prevention of epithelial-mesenchymal transition at early stage. However, the beneficial effect lost with increasing tubulointerstitial fibrosis.

ObjectiveTo summarize prenatal ultrasound image features of Cantrell′s syndrome (Cantrell′s pentalogy).MethodsFrom January 2007 to December 2013 in Shenzhen Maternity & Child Healthcare Hospital, there were twenty cases diagnosed and conifrmed by postmortem as Cantrell′s syndrome. The prenatal ultrasound image features and outcomes were analyzed.ResultsAmong the twenty cases, eighteen were singleton and two were twins with the other normal fetus. Prenatal ultrasound image: two obvious ultrasound image features of ectopic heart and hight omphalocele (seventeen cases) or gastroschisis (three cases) were appeared in prenatal ultrasound of twenty cases. Fourteen cases were complete ectopic heart (Ectopic heart was located within the omphalocele in one case, ectopic heart was completely exposed in amniotic lfuid in thirteen cases), six cases were incomplete ectopic heart, three cases were ventricular septal defect in which one was associated with pulmonary stenosis, two cases were single atrium and single ventricle in which one was associated with a single arterial trunk, one case was tetralogy of Fallot, and six cases were without signiifcant heart abnormalities. Associated with other abnormalities: seventeen cases were associated with other abnormalities in twenty cases, in which eleven cases were spinal abnormalities, nine cases were umbilical cord abnormalities (short umbilical cord in six cases, single umbilical artery in two cases, short umbilical cord associated with single umbilical artery in one case), ifve cases were neurological abnormalities (exencephalia in four cases, encephalocele in one case), four cases were limb abnormalities, three cases were cheilopalatognathus, one case was giant bladder. Three cases weren′t associated with other abnormalities. Nuchal Translucency: in eight cases, nuchal translucency were measured in early pregnancy. Nuchal translucency of ifve cases were thick, one case was cervical hygroma in one of the two twins. Chromosome examination results: only three cases had chromosome examination in twenty cases, in which one case was trisomy 21, another two were chromosome normal. Fetal outcome and examination results: in twenty cases, one of the two twins can′t survive after birth, and the other one of two twins was reduced in intrauterine, so the specimen could not be obtained. Eighteen cases of singleton underwent labor induction. The results of postmortem appearance (nineteen cases) and autopsies (ifve cases) were all consistent with prenatal ultrasound scan.ConclusionsEctopic heart and hight omphalocele or gastroschisis appearing at the same time was the characteristic of Cantrell′s syndrome in prenatal ultrasound and other abnormalities may be part of the Cantrell′s syndrome spectrum. It is beneift to detect and diagnose Cantrell′s syndrome by prenatal ultrasound in the ifrst trimester.

two-dimensional strain echocardiography can observe dynamic change of regional systolic function,combined with the two methods can more accurately assess the treatment results of coronary artery bypass surgery.

Objective To find biological markers to predict the mathematical cognitive ability in order to set patients free from the pain and time-consuming behavioral tests. Methods 86 patients with stroke or brain traumatic injuries were recruited and acquired T1 and rest-ing-state functional MRI imaging data. And a mathematical task (7 calculation items, 2 counting items) and a word-reading task (140 items) was also finished. The partial correlative analysis was made between the score of mathematical task and the amplitude of low frequency fluc-tuation of each voxel of the whole brain with the word-reading performance as controlling task, and AlphaSim correction method was used with corrected P<0.05 (single voxel level:P<0.05;cluster size:>110 voxels). Results There were 5 cerebral regions whose amplitude of low frequency fluctuation significantly correlated with mathematical performance:left inferior parietal lobule (161 voxels, rpeak=0.34), left precu-neus/superior parietal lobule (141 voxels, rpeak=0.31), left middle temporal gyrus (359 voxels, rpeak=0.34), left middle frontal gyrus (491 vox-els, rpeak=0.36), and right middle frontal gyrus (156 voxels, rpeak=0.32). Conclusion The amplitude of low frequency fluctuation of left inferior parietal lobule, precuneus/superior parietal lobule, middle temporal gyrus, middle frontal gyrus, and right middle frontal gyrus could be used as predictors of mathematical cognitive ability for brain-damaged patients.

Objective To evaluate MRI diagnostic value for single lesion characteristics in the splenium of corpus callosum.Methods MRI features,clinical data,and parts of follow-up results of 9 cases with single lesion in the splenium of corpus callosum were analyzed retrospectively.Results (1)Clinical manifestations:headache and dizziness occurred in 4 cases,syncope in 3 cases,fever in 2 cases, physical activity barriers in 2 cases.(2)Clinical diagnosis:hypoglycemic encephalopathy were rescaned one month later in 3 cases, in which the previous lesion completely disappeared.Clinical experience of encephalitis were improved after treatment in 2 cases. Cerebral infarction,epilepsy,brain injury and degeneration were diagnosed respectively in each one case,in which lesion still existed after treatmented.(3)Image findings:despite the different clinical manifestations,image features of all cases were quite similar. Round or foliated like lesions of slightly long T1 and long T2 signals in the splenium of corpus callosum were presented in all cases. High signals on diffusion weighted imaging and low signals on the ADC were showed with same lesions,andno obvious enhancement after contract media injected was seen.Conclusion Single lesions in the splenium of corpus callosum are showed in many diseases. The image features of hypoglycemic encephalopathy or encephalitis have certain characteristics (single lesion is reversible).Accurate diagnosis need to combine with clinical data and medical history.
