to observe the infarction volume.Nitrate reductase assay was used to detect the level of NO in brain tissue of the rats.The level of S100βin brain was detected by ELISA method.Results Compared with model group,the brain infarction volumes of the rats 24 and 72 h after cerebral ischemia reperfusion in curcumin group were significantly decreased (P<0.05).Compared with sham operation group,the NO and S100βlevels in the brain tissue 24 and 72 h after cerebral ischemia reperfusion of the rats in model group were significantly increased(P<0.05);compared with model group,the levels of NO in the brain tissue 24 and 72 h after cerebral ischemia reperfusion in curcumin group were remarkably decreased (P<0.05);compared with modee group,the level of S100βin the brain tissue 72 h after cerebral iscemia reperfusion in curcumin group was remarkably decreased (P < 0.05 ). Conclusion Curcumin can significantly reduce the degree of ischemia reperfusion injury in the rats and reduce the levels of NO and S100βin brain tissue,which suggests that the decrease of NO and S100βlevels in brain tissue may be associated with the neuroprotective effect of curcumin.
4. Placental mesenchymal dysplasia: a case report and literature review
Chinese Journal of Perinatal Medicine 2019;22(10):729-734
Objective:
To summarize the clinical, sonographic and pathological characteristics, and the perinatal outcomes of pregnancies complicated by placental mesenchymal dysplasia (PMD).
Methods:
We reported the diagnosis and treatment of a case of PMD in Tianjin Union Medical Center. Pertinent Chinese literatures on PMD were reviewed to analyze the clinical features and the outcomes for mothers and infants.
Results:
(1) Case report: The patient was admitted to our hospital with elevated blood pressure in July 2011 and underwent caesarean section at 30+1 gestational weeks indicated by severe preeclampsia and fetal distress. PMD was diagnosed by placental pathological examination. The patient was discharged from the hospital after oral antihypertensives treatment with stabilized blood pressure. Both the mother and the child were healthy during follow-ups until August 2018. (2) Literature review: A total of 14 cases of PMD were reported domestically including the index case. The average maternal age was 27.9(23-42). Of all the 14 fetuses, half were born alive and half were died in the uterus; two were male, 10 were female and two of unknown sex. Sonographic findings of 10 cases showed thickened placenta with hypoechoic areas. Human chorionic gonadotropin (hCG) was tested in five cases, and the results were all normal. One case was tested for maternal serum alpha fetoprotein (AFP), which was increased. Among the 14 cases, there were two of preeclampsia, six of intrauterine death, three of fetal distress and one of the premature rupture of fetal membranes. Four out of the seven live births were born prematurely. According to the medical record, the average weight of placentas of seven gravidas was 665 g, and eight placentas were larger than the gestational age in size. Pathological examinations showed 11 placentas were covered with grape-like cystic vesicles. No trophoblastic proliferation or stromal trophoblastic inclusion was observed in 12 cases under the microscope.
Conclusions
PMD is mainly characterized by enlarged and cystic placenta with hypoechoic areas in sonographic findings as well as elevated AFP and normal hCG concentrations in serum. It is more likely to occur in female fetuses with normal karyotype. Placentas with significantly increased size and weight and grape-like cystic vesicles are typical features of PMD that can be detected by pathological examinations. Some gravidas may develop hypertensive disorders of pregnancy and deliver prematurely due to fetal distress, but the maternal and neonatal outcomes are usually good. Close monitoring of the gravidas and fetuses with PMD may help to improve pregnancy outcomes.

Objective:
To analyze the clinical data of a family with early-onset familial Alzheimer′s disease and to analyze the mutation of the pathogenic gene in the family.
Methods:
The clinical data of a proband who was clinically diagnosed as early-onset Alzheimer′s disease in the Department of Neurology, People′s Hospital of Zhengzhou University in October 2018 and her family members were collected. Moreover, whole exome sequencing was performed on blood sample from the proband, then its deleterious effects were assessed according to the Standards and guidelines for the interpretation of sequence variants, a joint consensus recommendation of the American College of Medical Genomics. Subsequently, the strong pathogenic mutation was validated by Sanger sequencing in the some members of the family and 50 sporadic Alzheimer′s disease and 50 normal individuals of the family. Apolipoprotein E (APOE) typing of 10 family members was all epsilon 3/epsilon 3.
Results:
The proband in this family showed decreased memory, visual space disorder, verbal repetition, personality change and abnormal mental behavior. The mutation at codon 717 of exon 17 of the proband amyloid precursor protein gene was detected by gene detection. The mutation at codon 717 of exon 17 of the proband beta-amyloid precursor protein gene was also found in the other five members of the family. The mutation was not found in 50 sporadic Alzheimer′s disease patients and 50 normal individuals outside the family. The proband′s head magnetic resonance imaging (MRI) showed bilateral hippocampal atrophy on plain scan, especially on the left side. No obvious abnormality was found in the head magnetic resonance angiography. The head MRI of the proband′s sister showed brain atrophy and bilateral hippocampal atrophy.
Conclusions
The study identified the pathogenic mutation of the beta-amyloid precursor protein gene p.V717I in six patients of a family with early-onset familial Alzheimer′s disease, and the mutation showed a phenomenon of family segregation. This finding is of great significance to the study of early-onset Alzheimer′s disease in Chinese population.
