Objective To evaluate the effects combining in situ amniotic fluid culture with chromosomal microarray analysis(CMA)in prenatal diagnosis of fetal chromosomal abnormalities.Methods A retrospective analysis was conducted on 3 133 pregnant women who underwent amniocentesis at Huaihua Maternal and Child Health Hospital from October 2018 to February 2023 due to different indica-tions for prenatal diagnosis.The detection rates and differences of in situ amniotic fluid culture and CMA in detecting fetal chromosomal abnormalities were compared.Results Among the 3 133 samples,the detection rates increased by 0.95％(in situ culture)and 2.36％(CMA)in the double-indication group compared with the single-indication group.The combined testing detected 796 abnormal cases(25.41％),including 300 cases(9.58％)by in situ culture and 706 cases(22.53％)by CMA.Both techniques detected 145 aneu-ploidies and 31 large segmental structural abnormalities,while CMA additionally detected 169 copy number variants(CNV),loss of heterozygosity(LOH),absence of heterozygosity(AOH)/region of homozygosity(ROH)and uniparental disomy(UPD),and in si-tu culture additionally detected 11 balanced rearrangements.They jointly detected 23 cases of mosaicism(0.73％).Conclusion In si-tu amniotic fluid culture and CMA complement each other.Their combined application can significantly improve the detection rate of fe-tal chromosomal abnormalities and provide more detailed and accurate information for prenatal genetic counseling,thus facilitating preg-nant women to decide continuing or terminating the pregnancy.

Day surgery, as a new perioperative management model that is safe, efficient, and consumes a small amount of medical resources, has been widely recognized in recent years. With the requirements of China's new healthcare system reform and the promotion of national policies, there is a significant increase in hospitals carrying out day surgery, and they are about to enter a new stage of rapid development. Adequate preoperative evaluation of patients undergoing day surgery is an important link in improving perioperative care during day surgery. This article reviews the importance, location and personnel, methods, timing and content of day surgery preoperative evaluation, and current situation of day evaluation in China, in order to provide reference for clinical workers related to day surgery.

Objective:To retrieve, evaluate, and integrate the best evidence for preoperative evaluation and management of adult day surgery patients.Methods:The guidelines, evidence summary, systematic review, expert consensus and randomized controlled trial on preoperative evaluation and management of adult day surgery patients were systematically searched on Guidelines International Network, Chinese Clinical Guidelines Library, Clinical Practice Guideline of Canadian Medical Association, Scottish Intercollegiate Guidelines Network, Yimaitong, New Zealand Guidelines Group, China Ambulatory Surgery Alliance, National Institute for Health and Clinical Excellence, Chinese Medical Journal Network, Agency for Healthcare Research and Quality, UpToDate, Cochrane Library, Australian Joanna Briggs Institute Evidence-Based Healthcare Center Database, British Medical Journal (BMJ) Best Practice, PubMed, Web of Science, CINAHL, Elsevier, Embase, Medline, WanFang Data, China National Knowledge Infrastructure, China Biomedical Literature Database and other databases. After conducting methodological quality evaluation, evidence was extracted and integrated based on the theme. The search period was from the establishment of the database to May 15, 2023. Two researchers trained in evidence-based knowledge conducted a rigorous literature quality evaluation, evidence extraction, and integration of all included literature.Results:A total of 12 articles were included, including two guidelines, six evidence summaries, three expert consensus and one randomized controlled trial. A total of 24 pieces of evidence were collected from five aspects, including evaluation timing and evaluation method, evaluation personnel, evaluation location, evaluation content, education and training, and quality improvement.Conclusions:The best evidence for preoperative evaluation and management of adult day surgery patients provides evidence basis for clinical medical and nursing staff to conduct preoperative evaluation and management comprehensively and effectively.

OBJECTIVETo observe the biological characteristic and the prognoses in patients with acute erythroleukemia (AEL).

METHODSThe results of 167 patients with newly diagnosed AEL, from January 2003 and June 2013 in the First Affiliated Hospital of Soochow University, were reviewed by MICM.

RESULTSFlow cytometry analysis indicated that CD13(96.1%), CD33(95.1%), CD117(87.4%) and CD34 (79.4%) were highly expressed in AEL. 56 of 148 (37.8%) AEL patients had a variety of cytogenetic abnormalities, 27 of 148(18.2%) patients were complex karyotype (abnormalities involving 3 or more chromosomes), the abnormalities of chromosomes 3, 5, 7 and 8 were more frequently involved and the most common one was ＋8, accounting for 35.7% of all abnormal karyotype, followed by 5q- (17.9%). Mutation analysis showed CEBPA mutation ratio of AEL patients was 44.0% (11/25), that of NPM1 as 15.4% (4/26). Initial induced remission rate of AEL was 56.6% (30/53), compared by 33.3% (4/12) of MDSM6. Survival analysis showed that the overall survival in female was better than that in male (P=0.047). The overall survival time of transplantation group is significantly longer than chemotherapy group (P=0.000). The OS of 13-39 years old group was the best, 40-49 years old group took second place, >50 years old group appeared to be the worst.

CONCLUSIONAEL had its own unique biological features, and allogeneic hematopoietic stem cell transplantation could significantly improve its poor prognosis.
