Journal of Xi'an Jiaotong University(Medical Sciences) 1981;0(03):-
In this paper, Paraffin and Frozen sections of cysticercus cellulosae cysts were used as antigens in IFA for diagnosis of cysticercosis. The results showed that the positive rates of 92 sera and 51 sera from the patients with cysticercosis that had been confirmed were 90% and 94%. respectively, Both of them have no significant difference This shows that both the paraffin and Frozen section have the same sensitivity. The former also has the advantages of convenience in production, and there is no need for low temperature equipment. When using the two section antigens, there were cross reactivity between the sera from patients of cysticercosis and the sera from patients of hydatidosis and clonorchiasis, while the tested 30 sera from healthy persons were negative reaction.

Objective To isolate and identify the putative Japanese encephalitis virus (JEV) re-ceptors from C6/36 and Vero cells. Methods Molecules binding with JEV were isolated from C6/36 and Vero cells by co-immunoprecipitation (Co-IP) approach, identified by mass spectrometry, and detected by Western blot. The location of putative JEV receptor on cells membrane and the binding with JEV were ob-served by laser scanning confocal microscopy (LCM). Results Several molecules binding with JEV were isolated from C6/36 and Vero cells by Co-IP, and only one molecule was identified as heat shock cognate 70 (HSC70) by mass spectrometry. Antibody against HSC'70 was able to detect a 74 ×103 protein isolated by Co-IP from C6/36 and Vero cells membrane in Western blot assays. It was observed by LSCM that when JEV attached on the surface of C6/36 cells, JEV and HSCT0 protein were co-localization. Conclusion 74 x 103 molecular identified as HSC70 protein from C6/36 cells may be JEV receptor.

ObjectiveTo investigate the karyotypes of amiotic fluid cells and compare the incidence of chromosomal abnormality as well as to evaluate the clinical significance of abnormal karyotypes. MethodsA total of 13 648 pregnant women came to Shanghai Jiai Genetics and IVF Institute, Obstetrics and Gynecology Hospital, Fuclan University to do amniocentesis from September 1998 to November 2010, and 13 795 amniotic fluid specimens were successfully extracted and cultured, thus 13 795 fetuses received karyotype diagnosis. These fetuses were grouped according to different indications. If maternal age was ≥ 35, the fetuses were grouped into the advanced maternal age group (4065) ; and if maternal serum screening test revealed high-risk of trisomy 18 or trisomy 21, the fetuses were grouped into the high-risk serum screening group (6462) ; and those with abnormal signs of ultrasound screening were grouped into the abnormal ultrasound signs group (1539); and if either of the parents was with chromosome abnormalities, the fetus was grouped into the paternal/maternal abnormality group ( 108 ) ; whereas the remainder were grouped in other factors group ( 1621 ). The amniotic fluid cells were in-situ cultured on coverslips, harvested by conventional G-banded methods, and then analyzed by two doctors. In order to get rapid diagnosis, some pregnant women whose gestational age ≥26 weeks accepted fluorescense in situ hybridization (FISH). FISH was done on 78 uncultured amniotic fluid specimens using probes located at chromosome 13,18,21, X,Y. Some parents were required to analyze lymphocyte karyotype to help judging the origin of abnormal karyotype. Results( 1 ) Classification and composition of abnormal karyotypes in each group : a total of 388 abnormal karyotypes were found among 13 795 fetuses, and the abnormal rate was 2. 813% (388/13 795).Of the 388 fetuses, aneuploidy was the most common pattern which was up to 59. 8%(232/388);autosomal structural abnormality rate was 24. 7% ( 96/388 ) ; mosaicism was 12.4% (48/388). Other uncommon abnormal karyotypes included marker chromosome (5/388,1.3%), sex chromosomal structural abnormality (4/388,1.0%) and triploid (3/388, 0. 8% ). Aneuploidy was the most common in most groups except the patemal/matemal abnormality group. There were four cases of rare aneuploid in the advanced maternal age group,the high-risk serum screening group and the abnormal ultrasound signs group respectively. Every type of abnormality could be found in the abnormal ultrasound signs group, and autosomal structural abnormalities were concentratedin paternal/maternalabnormality group. Mosaicism mainly distributed in the high-risk serum screening group, accounting for 20. 0% (29/145) of abnormalities in this group. (2) Abnormal types and the incidence: the most common type was trisomy 21 ( 138/388,35.6% ),followed by autosomal balanced structural rearrangements( 80/388, 20. 6% ), mosaicism(48/388,12. 4% )and trisomy 18 (44/388,11.3% ). Others included non-balanced autosomal structural rearrangements (16/388,4. 1% ), 45 ,X0 ( 16/388,4. 1% ) and 47 ,XXY( 15/388,3.9% ). (3) Lymphocyte karyotype analysis of the couples: parents of 153 fetuses were analyzed to determine the origin of abnormal karyotype. Fifty-eight familial and 95 de novo abnormalities were found. FISH results were the same with G-banding karyotype, and two of these were trisomy 21. Conclusions Abnormal karyotype composition is different according to different maternal amniocentisis indications. There is a variety of abnormal karyotypes in the second trimester pregnancy, and the risk of fetal malformation is related with the kind of abnormal karyotype.

This study aims to investigate the effect of total flavones of Fructus Chorspondiatis (TFFC) on the mRNA and protein expression of collagen type I and III of rat cardiac fibroblasts (CFs) induced by angiotensin II (Ang II), and explore its anti-myocardial fibrosis molecular mechanism. Neonatal rat CFs were prepared from Sprague-Dawley rats (1-3 d after birth). The expression of collagen type I and III mRNA and protein were measured by RT-PCR and Western blotting, respectively. The study showed that stimulation of neonatal rat CFs with 100 nmol.L-1 of Ang II for 72 h resulted in a significant increase of the expression of collagen type I and III mRNA and protein. The changes on the expression level were blocked by TFFC. The results demonstrated that TFFC can inhibit myocardial fibrosis induced by Ang II in rats, which is probably associated with the collagen type I and III mRNA and protein levels up-regulated by Ang II, and TFFC was shown to decrease the expression levels of collagen type I and III mRNA and protein.

Objective To further determine their possible synergistic effect on accelerating wound healing, adenovirus vector containing recombinant human hPDGF-A and hBD2 genes was constructed and the expression of exogenous genes in transformed mesenchymal stem cells derived from rat bone marrow was observed. Methods By putting IRES in the middle of hPDGF-A and hBD2, these two genes were expected to be expressed individually. The shuttle vector was named as pAdTrack-hPDGF-A-IRES2-hBD2, which homologously recombinated with Adeasy-1 in BJ5183 cells and formed the mammalian expression vector pAdeasy-hPDGF-A-IRES2-hBD2. Furthermore, the recombinant vector was packaged in 293 cells into infectious recombinant adenovirus, which were used to infect BMSCs. The expression of hPDGF-A and hBD2 in BMSCs was detected by RT-PCR. Results We successfully constructed recombinant adenovirus vector that simultaneously expressed hPDGF-A and hBD2. The expressions of hPDGF-A and hBD2 were confirmed by RT-PCR on transformed BMSCs. Conclusion The established BMSCs that overexpressed hPDGF-A and hBD2 provide a new strategy of combining cell therapy and gene therapy to promote wound healing, especially the chronic one.
