ABSTRACT

Objective:To understand the knowledge, attitude and practice of edema in patients with critically illness of ICU nurses, and to analyze its influencing factors.Methods:After developing the Knowledge-Attitude-Practice Scale of Edema Status in Critically Ill Patients for ICU nurses by Delphi expert consultation method, the level of knowledge, attitude and practice of edema status of ICU nurses in six tertiary hospitals in Shanghai City was investigated by using convenience sampling method.Results:A total of 292 ICU nurses were investigated by questionnaire. The total scores of knowledge dimension, attitude dimension and practice dimension of critical patients with edema in ICU nurses were 38.27 ± 5.52, 58.33 ± 8.34 and 43.04 ± 8.05, respectively. Multiple stepwise regression analysis showed that age ( β=0.28, P<0.05) was the main factor affecting ICU nurses′ knowledge about edema state of critically ill patients; age( β=0.20, P<0.05) and education ( β=0.28, P<0.05) were the factors affecting ICU nurses' attitude towards edema state of critically ill patients; and years of nursing work ( β=0.28, P<0.05) was the factor affecting the practice of critically ill patients of ICU nurses. Conclusions:The level of knowledge and attitude towards edema in critically ill patients of ICU nurses is good, but the level of behavior is general. Nursing managers should strengthen the training related to edema for ICU nurses, further to form a standardized prevent-treatment plan and nursing process in order to actively improve the nursing practice of edema in critically ill patients.

ABSTRACT

Objective:To provide a promising and optimal laboratory susceptibility-testing method for the clinical usage of antibiotic (polymyxin), four susceptibility-testing methods were performed and the broth microdilution (BMD) was chosen as the gold standard.Methods:A total number of eighty-eight nonduplicate clinical Enterobacteriaceae specimes were collected from January to December of 2019 in the First Affiliated Hospital, Fujian Medical University. Among the clinical specimens, of which six strains were positive for mcr-1. The minimal inhibitory concentration (MIC) of polymyxin of the clinical specimens were examined by the following methods: (1) broth microdilution, (2) colistin broth disk elution, (3) Vitek-2?, (4)BD PhoenixTM,(5)commercial broth microdilution. With BMD as reference, essential agreement (EA), categorical agreement(CA), very major error(VME) and major error (ME) of polymyxins for different methods were analyzed. The Kappa-consistency testing, paired Chi-square testing and the Spearman-rank correlation testing were used to analyze the consistency between the four antimicrobial susceptibility testing methods and the gold standard.Results:Taking broth microdilution as reference, the EA of colistin broth disk elution, Vitek-2?, BD PhoenixTM, commercial broth microdilution were 94.32% (83/88), 92.05% (81/88), 90.90% (80/88), and 96.59%(85/88), respectively. The CA of all the four methods were 100% (88/88). No VME and ME were recorded for four methods. Moreover, the consistency between four susceptibility testing methods and the gold standard is acceptable (Kappa values=1, P<0.001, McNemar test P=1 and r>0.5, P<0.05). Conclusions:In the present work, four susceptibility testing methods all met the standards recommended jointly by the Clinical and Laboratory Standards Institute and European Committee on Antimicrobial Susceptibility Testing, of which the performance of the commercial broth microdilution and CBDE fared relatively well. Thus, these four methods could be routinely used in clinical microbiology laboratory of our hospital for colistin and polymyxin B susceptibility testing.

ABSTRACT

OBJECTIVE@#To determine the chromosomal karyotype of a fetus with copy number variation (CNV) of the X chromosome signaled by non-invasive prenatal testing (NIPT).@*METHODS@#NIPT was performed on the peripheral blood sample taken from the pregnant women. Amniotic fluid and cord blood samples were subjected to conventional G banded karyotyping, and were further analyzed by high-throughput sequencing for chromosome microdeletion/microduplication. The results were then verified by fluorescence in situ hybridization (FISH) on metaphase cells.@*RESULTS@#The NIPT test of pregnant women suggested low risk for 21-trisomy, 18-trisomy, and 13-trisomy, whilst indicated the number of chromosome X to be low. The G banded karyotype of the amniotic fluid and cord blood cells was 46,XX. The result of high-throughput sequencing chromosome microdeletion/microduplication detection was seq[hg19](X)× 1, (Y)× 2. FISH showed a clear red signal at each end of a whole chromosome, and a green signal on the other chromosome, with a karyotype of 46,X,ish idic(Y) (q11.23) (SRY++, DXZ1+). C banding showed that there is a dense and a slightly loose centromere at both ends of the Y chromosome, and the parachromatin region was missing. The karyotype of amniotic fluid and cord blood cells was finally determined to be 46,X, pus idic(Y) (q11.23).@*CONCLUSION@#For chromosome anomalies suggested by auxiliary report of NIPT, conventional karyotyping combined with high-throughput sequencing for chromosome microdeletion/microduplication should be adopted for the prevention and reduction of the rate of chromosome microdeletion/microduplication syndromes.

ABSTRACT

Objective To explore the direction value of endovascular pressure differences in endovascular management of subclavian steal syndrome (SSS).Methods Eleven SSS patients accepted endovascular management,admitted to our hospital from January 2016 to December 2017,were collected in this study.Before and after operation,pressure-sensing wire was used to measure endovascular pressure differences (mean distal stenosis pressure minus mean proximal pressure),digital substraction angiography (DSA) was used to assess the stenotic rate,transcranial doppler (TCD) was used to assess the steal degrees,and electronic sphygmomanometer was used to measure the systolic pressure differences between bilateral brachial arteries.The pressure differences before and after endovascular management were compared.Before operation,the relations of pressure differences with stenotic rate,steal degrees and systolic pressure differences between bilateral brachial arteries were analyzed.After operation,the relations of pressure differences with stealing and clinical symptom improvements were analyzed.The predictive values of pressure differences and residual stenosis in clinic success were compared.Results (1) After operation,the blood stealing disappeared and the clinical symptoms improved in 10 patients;although residual stenotic rate of one patient decreased obviously,blood stealing and clinical symptoms still existed after operation;the clinic success rate was 90.9%(10/11).(2) Pressure differences before surgery ([11.2±5.7] mmHg) were significantly higher as compared with those after the surgery ([2.5±5.3] mmHg,P<0.05).(3) Before operation,pressure differences were significantly correlated with stenotic rate (r=0.757,P=0.007) and bilateral systolic pressure differences (r=0.701,P=0.016).Six patients had pressure differences of 6-9 mmHg,enjoying degree I and Ⅱ of stealing,and 5 patients had pressure differences ≥ 10 mmHg,enjoying degree Ⅲ of stealing.(4) After operation,pressure difference was 18 mmHg in one patient without clinic success,but pressure differences were ≤ 3 mmHg in 10 patients with clinic success.(5) Significant difference was noted between the two clinic success indexes (residual stenotic rate ≤ 30% by DSA and pressure differences ≤ 3 mmHg,P<0.05).Conclusion Endovascular pressure differences can reflect the hemodynamic changes before and after endovascular management;as compared with residual stenosis,it is better to predict the clinic success after operation;it is useful to guide the endovascular management in the SSS patients.

ABSTRACT

OBJECTIVE@#To analyze the clinical and molecular biological characteristics of a neonate with myeloid proliferation related to Down syndrome (DS).@*METHODS@#The neonate, who was suspected for Down syndrome, was analyzed in terms of clinical feature, peripheral blood cell morphology, fluorescence in situ hybridization (FISH), immunological classification and other laboratory tests. On hundred and fourteen leukemia-related genes were subjected to next-generation sequencing (NGS).@*RESULTS@#Laboratory test revealed obvious abnormal liver function and coagulation function, anemia, and extreme leukocytosis. Cell smear indicated significantly increased progenitor cells, which conformed to proliferation of megakaryocytes. FISH showed trisomy 21. By NGS, c.220+dupT, a novel mutation, was identified in exon 2 of the GATA1 gene, which encodes a N-terminal activation domain and has a frequency of 95.8%. No mutation was identified among the remaining 113 genes.@*CONCLUSION@#The neonate had DS and GATA1 gene mutation. High percentage of circulating blasts should be considered as transient myelodysplasia but not congenital leukemia.

ABSTRACT

OBJECTIVE@#To explore the effect of small interfering RNA (siRNA)-mediated CEP55 gene silencing on the proliferation of mouse spermatogonia.@*METHODS@#Six patients with azoospermia diagnosed to have maturation arrest (3 cases) or normal spermatogenesis (3 cases) based on testicular biopsy between January 1 and December 31, 2017 in our center were examined for differential proteins in the testicular tissue using isobaric tags for relative and absolute quantitation (iTRAQ), and CEP55 was found to differentially expressed between the two groups of patients. We constructed a CEP55 siRNA for transfection in mouse spermatogonia and examined the inhibitory effects on CEP55 expressions using Western blotting and qPCR. The effect of CEP55 gene silencing on the proliferation of mouse spermatogonia was evaluated with CCK8 assay.@*RESULTS@#In the testicular tissues from the 6 patients with azoospermia, iTRAQ combined with LC/MS/MS analysis identified over two hundred differentially expressed proteins, among which CEP55 showed the most significant differential expression between the patients with maturation arrest and those with normal spermatogenesis. The cell transfection experiment showed that compared with the cells transfected with the vehicle or the negative control sequence, the mouse spermatogonia transfected with CEP55 siRNA showed significantly lowered expressions of CEP55 mRNA and protein ( < 0.05) and significantly decreased proliferation rate as shown by CCK8 assay ( < 0.05).@*CONCLUSIONS@#CEP55 may play a key role in spermatogenesis and may serve as a potential therapeutic target for non-obstructive azoospermia with maturation arrest.

ABSTRACT

OBJECTIVE@#To explore the causes of oocyte vitrification and its application in assisted reproduction.@*METHODS@#We retrospectively analyzed the data of 26 patients with 27 cycles of oocyte vitrification cryopreservation undergoing intracytoplasmic sperm injection (ICSI) and embryo transfer between January, 2008 and October, 2018. The causes of oocyte vitrification and the outcomes of ICSI and clinical pregnancy were analyzed.@*RESULTS@#The causes of oocytes vitrification included mainly azoospermia or severe spermatogenesis disorder of the husband, failure to obtain sperms from the husband, failure of the husband to be present on the day of oocyte retrieval and acute diseases of the husband to not allow sperm collection. A total of 274 oocytes were frozen in 27 oocyte retrieval cycles, and 217 eggs were thawed in 19 cycles with a survival rate of 81.11% (176/217). The normal fertilization rate, cleavage rate and high-quality embryo rate was 74.81% (98/131), 89.80% (88/98) and 36.73% (36/98), respectively. Fifteen patients underwent embryo transfer, and the clinical pregnancy rate and live birth rate was 53.33% (8/15) and 33.33% (5/15), respectively. Compared with patients below 35 years of age, the patients aged above 35 years had significantly lower oocyte survival rate after thawing (82.76% 74.42%, =0.211), clinical pregnancy rate (77.78% 16.67%, =0.041) and live birth rate (55.56% 0, =0.044).@*CONCLUSIONS@#Oocytes vitrification can be used as a remedy for infertile couples who fail to provide sperms due to male factors on the day of oocyte retrieval. Vitrification of the oocytes does not significantly affect the fertilization rate or the clinical pregnancy rate. The survival rate of the thawed oocytes is related to the age of the wife, and an age younger than 35 years can be optimal for achieving favorable clinical pregnancy outcomes after oocyte vitrification.

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the deletion region for two fetal cases with large Yq deletions in order to provide genetic counseling and prenatal diagnosis.</p><p><b>METHODS</b>For both cases, amniotic fluid samples were cultured and analyzed with G banding and fluorescence in situ hybridization (FISH). Multiplex polymerase chain reaction was also carried out to amplify 15 sequence tagged sites (STS) of azoospermia factor (AZF) on the Y chromosome.</p><p><b>RESULTS</b>For both samples, the karyotypes were determined as 46,X,del(Y)(pter→q11:). No heterochromatin was found in C band. The karyotypes of their fathers were 46,XY, and heterochromatin was found in C band. STS analyses suggested that only sY82, sY84 and sY86 in AZFa were amplifiable while the other 12 STS were negative in amniotic fluid for the first case, which indicated deletions of AZFb, AZFd and AZFc. No AZF deletion was found in its father. For the second case, all 15 STS were amplifiable in the amniotic fluid, suggesting no AZF deletion. No AZF deletion was found in its father too.</p><p><b>CONCLUSION</b>Conventional karyotyping combined with FISH and molecular genetics techniques can enable characterization of AZF microdeletions and facilitate genetic counseling and prenatal diagnosis.</p>

ABSTRACT

Objective To investigate the clinical features of internal carotid steal syndrome. Methods The clinical manifestations, CT or MRI, digital subtraction angiography, and blood flow compensation in 6 patients with internal carotid steal syndrome were analyzed. Results Of the 6 patients, 2 had unilateral internal carotid artery stenosis, 4 had severe stenosis (in which 2 were on the left side, 1 was on the right side, and 1 was on both sides). The clinical manifestations of the patients with internal carotid steal syndrome were watershed infarction and transient ischemic attack. Four patients had posterior circulation ischemia and 2 had anterior circulation ischemia. Digital subtraction angiography demonstrated that collateral circulation was established in all the 6 patients. The anterior communicating artery, posterior communicating artery, and pial artery were the common compensatory vessels. Conclusions Internal carotid artery steal syndrome can be presented as anterior or posterior circulation ischemia, and the collateral circulation plays an important role in the compensation.
