Objective To investigate chromosomal aneuploidy of chorionic villior tissue from embryo arrestor spontaneous miscarriage by the method of multiplex ligation-dependent probe amplification(MLPA), and to provide genetic etiology data for recurrent spontaneous abortion(RSA) and embryo arrest.Methods The clinical retrospective analysis was used during November 2013 to October 2016 in Shenzhen Maternity and Child Healthcare Hospital.The genomic DNA of 7 036 chorionic villi or tissue samples from embryo arrestor pregnancy loss were extracted by resin and Proteinase K, following detected by multiplex ligation-dependent probe amplification, and then analyzed by descriptive and frequency statistic using SPSS17.0 software.Results Totally 2 984 samples (42.41%) with chromosomal aneuploidy were detected, of which, the top five were trisomy 16(826)11.74%, monosomy X (Turner,401)5.70%, trisomy 22(247)3.51%, trisomy 13(149)2.12% and trisomy 21(144)2.05%.Aneuploidy 19 or 17 were rare,just 1 and 3 cases respectively.The aneuploidy of chromosome 1 was not discovered yet.There were 161 samples (2.28%) for segmental deletion and/or duplication cases.Besides of the monosomy X(Turner,401), monsomy 21 was also high frequency(17,0.24%).In addition, 56 samples(0.80%)were double trisomic,while 2 samples(0.03%)were tris-trisomy.Thirteen samples(0.18%)were heterosome trisomy,and five samples(0.07%)were Turner combined trisomy.Fifteen samples(0.21%) were unbalanced translocation of the arm,while 20 samples(0.28%) were nonhomologous chromosome translocation.Conclusions Trisome and monosome were the majority of chromosome abnormality (above 90%), as well as the main cause of spontaneous miscarriage.Meanwhile the chromosome aneuploidy (including segment deletion or duplication) could be screened by MLPA quickly, thoroughly and efficiently, further more discover the carrier of balanced translocation in couples and provide valuable genetic information for next pregnancy.

Object To determine the diumal changes of photosynthesis, its relationships with light intensities and temperatures, and the contents of chloroophyll in leaves of Dendrobium candidum Wall. ex. Lindl., D. wilsonii Rolfe and D. hercoglossum Reichb. f. Methods The net photosynthetic rate (NPR) was measured at intervals of 1.5 h during daytimes 7:30—16:30, under the photosynthetic affective rates 0—140 mmol/(m 2?s), and under the temperatures 29.6—38.2 ℃; contents of chlorophyll a and b in leaves were measured. Results NPR, light saturation point and compensation point were low in each of the three Dendrobium L. species. The NPR peaked during 8:00 and 10:00 am, and thereafter decreased rapidly as the temperature and light intensity increased. Content of chlorophyll b was high in the leaves. Conclusion These results indicated that the Dendrobium L. species, which are sciophyte plants, have great adaptations to their growing habitats.

Objective To survey and analyze the etiology of pericardial effusion in different age patients. Methods The data of 450 patients who were diagnosed as pericardial effusion were studied retrospectively. The pathogenesis of pericardial effusion were analyzed and compared among the five age groups : juvenile group (0-19 years),young group (20-39 years),middle age group (40-59 years), aged group (60-79 years) and existed advanced age group (≥80 years). Results The different pathogenesis of pericardial effusion existed in different age groups. The first three causes are tumor, tuberculous, heart failure in all patients. As a pathogeny, cardiopulmonary insufficiency induced pericardial effusions constitute the majority (about 50%) in the advanced age group. Tumor, heart failure are the main causes in aged group. In middle age group, tumor and tuberculous are the most frequent pathogenesis, while the tuberculous is the principal causes in juvenile and young groups. Conclusions The rate of tumor, heart failure, lung infection raised along with the age increasing in the patients with pericardial effusion, meanwhile the cases of tuberculoses declined. Attention should be given to this tendency on the diagnosis and treatment of the patients with pericardial effusions.

Objective To investigate the changes of plasma adrenomedullin(ADM) and C-type natriuretic peptide(CNP) levels with elderly hypertension(HPE).Methods The plasma levels of ADM and CNP were measured by radioimmunoassay in 136 cases of the HPE(group A) compared with that of in 40 cases healthy elders(group B).Results The plasma levelsof ADM and CNP increased significantly in group A compared with group B(P

Objective To observe the changes of plasma adrenomedullin(ADM) and endothelin-1(ET-1),angiotension Ⅱ(Ang-Ⅱ) levels and their clinical significance in the patients with elderly hypertension(HPE).Methods The plasma levels of ADM and ET-1,Ang-Ⅱ were measured by radioimmunoassay in 136 patients with HPE compared with that of in 40 casers of health elders.Results The plasma levels of ADM and ET-1,Ang-Ⅱ were increased significantly in HPE compared with health elders(P

Objective To evaluate evidence-based practice of catheter removal strategy in patients with short-term indwelling catheter after partial nephrectomy. Try to apply the best evidence into practice, and further to improvethe quality of clinical nursing through quality review. Methods Two rounds of quality review were carried out in the 2 wards from July to December in 2016. Using the 5 review criteria of best evidence, we reviewed baseline of catheter removal strategies for patients with short-term indwelling catheter after partial nephrectomy and developed appropriate evidence-based practice. Further, the best evidence was integrated into clinical nursing practice, and the prognosis was reviewed after then. Results In the baseline review, the compliance of the 5 review criteria was 0. However, after introducing the best evidence into nursing practice,the compliance was up to 100%. The mastering of evaluation knowledge of catheter removal of nurses increased from 73.00 ± 9.35 to 94.81 ± 3.38 with significant difference (t=12.72, P<0.01). The indwelling time of catheter shorted from (5.69±0.79) d to(4.24±0.82) d. The difference was significant (t=5.47, P<0.01). Conclusions Evidence-based nursing practice improvesthe strategies of short-term catheter removal after partialnephrectomy, while closer cooperation between nurses and doctors are still needed to promote the continuous improvement of nursing quality.

Objective To discuss the application effect of brain natriuretic peptide (BNP)and QRS wave in nursing intervention of postmenopausal women with heart failure.Methods 85 postmenopausal women with heart failure in our department were chosen.43 patients in the control group were given routine nursing,42 patients in the observation group were given pertinent nursing according to BNP concentration and QRS wave.The alleviation rate of symptoms,reoccurrence rate of heart failure,mortality rate,NP concentration and QRS wave time limit and hospitalization days were compared between two groups.Results The reoccurrence rate of heart failure,mortality rate,NP concentration and QRS wave time limit and hospitalization days in the observation group were lower than those of the control group,but the alleviation rate of symptoms was higher than that of the observation group.Conclusions To give pertinent nursing according to BNP concentration and QRS wave for postmenopausal women with heart failure can alleviate symptoms,decrease attack of heart failure,shorten hospitalization days,improve cardiac function and prognosis,which is worthy of clinical application.

Objective Detection of single nucleutide polymorphisms in CD31-563 codon by denaturing high-performance liquid chromatography(DHPLC). Methods The eighth exon fragments of CD31 code gene in chromosome 17q23 were amplified by PCR. The fragments were analysed with DHPLC and were sequenced and compared with the sequences available in National Center for Biotechnology Information ( NCBI) database. Results The length of the amplified fragments is 203bp. There are three kinds of pictures when the fragments are analysed by DHPLC, after comparing with direct sequencing, the pictures of G/G homozygous、A/A homozygous、G/A heterozygous are obviously different, thus the individuals with the three kinds of genetype can be distinguished accurately. In 74 healthy people studied,the gene frequencies of CD31-563S(AGC) is 0.514, the gene frequencies of CD31-563N( AAC) is 0. 486. Conclusion DHPLC can effectively, economically and accurately detect the single nucleutide polymorphisms in CD31 -563 codon.
