Objective To analyze the clinical application of high?throughput gene sequencing technolo?gy and STR in chromosome karyotype analysis of the villus tissues of spontaneous abortion. Methods In 27 ca?ses of spontaneous abortion after pregnancy,classic cell of villus tissues culture and chromosomal karyotype anal?ysis,and high ?throughput gene sequencing technology and STR were performed,and then compared the analysis results of two methods. Results ( 1) The successful rate of cell of villus tissues culture and chromosomal karyo?type analysis was 85%( 23/27) ,of high?throughput gene sequencing technology and STR was 96%( 26/27) ,and the difference was not significant( P>0. 05) ( 2) In the 4 cases that failed in karyotype analysis,there were 3 ca?ses showed abnormal chromosomal number variation( CNV) in high?throughput gene sequencing technology and STR. ( 3) Of the 23 cases,chorionic villus was successfully cultured in 10 cases,abnormal karyotypes were iden?tified in 13 cases,the positive rate was 57%. Of the 26 cases,high?throughput gene sequencing technology and STR was successfully checked in 3 cases,abnormal CNV were identified in 23 cases,the positive rate was 85%, the difference was significant(χ2=6.387,P<0.05). (4)The rates of chromosomal number abnormality were 52%( 12/23) and 50% ( 13/26) of karyotype analysis and chromosome aberration detection,respectively. In 10 cases of normal cell culture karyotype,there were 7 cases in the presence of micro deletion / micro repetition de?tected by high?throughput gene sequencing technology and STR. Conclusion The method of massively parallel sequencing in chromosome analysis,compared with the method of cell of villus tissues culture and chromosome a?nalysis,can be accurate and quick,and has high successful rate in detecting the chromosome of non aneuploid and deletion/duplication abnormality,which can be a good complementary and alternative method of the classic cell of villus tissues culture and chromosome karyotype analysis.

Objective To evaluate the quality of intraoperative wake?up test in the patients undergoing scoliosis correction surgery under etomidate?based anesthesia. Methods Thirty patients of both sexes, aged 13-32 yr, weighing 40-65 kg, of ASA physical statusⅠorⅡ, undergoing elective scoliosis correction surgery, were randomly assigned into etomidate group ( group E, n=15 ) or propofol group (group P, n=15) using a random number table. Anesthesia was induced with etomid 0.3 mg∕kg (group E) or propofol 2mg∕kg ( group P ) injected intravenously, midazolam, fentanyl and rocuronium. The patients were mechanically ventilated after naso?tracheal intubation. Etomidate 0.6-1. 2 mg · kg-1 · h-1 and propofol 8- 10 mg·kg-1 ·h-1 were infused intravenously during surgery in E and P groups, respectively. Both remifentanil and cisatracurium were used for maintenance of anesthesia in the two groups. Cisatracurium infusion was stopped before wake?up test. The infusion rate of propofol was adjusted to 4 mg·kg-1 ·h-1 at 15 min before wake?up test. After the scoliotic angle was corrected, infusion of etomidate and propofol was stopped, and the infusion rate of remifentanil was adjusted to 0.025μg·kg-1 ·min-1 in both groups. The wake?up time was recorded, and the quality of wake?up was assessed. Mean arterial pressure (MAP) and heart rate were recorded before anesthesia ( T0 ) , immediately before the patients were awakened ( T1 ) , when the patients responded to commands from doctors ( T2 ) , and after anesthesia was deepened ( T3 ) . At T0 , the end of surgery ( T4 ) , and 24 h after surgery ( T5 ) , blood samples were collected from the internal jugular vein for determination of plasma cortisol concentrations. Results The patients were awakened successfully in the two groups, and there were no significant differences in the wake?up time, quality of wake?up, and MAP, HR and plasma cortisol concentrations at each time point between the two groups. MAP and HR were significantly higher at T2 than at T0 in the two groups. MAP and HR were within the normal range during wake?up test, and no patients developed severer cardiovascular events in the two groups. Conclusion Etomidate?based anesthesia provides better quality of intraoperative wake?up test in the patients undergoing scoliosis correction surgery, which is similar to that of propofol?based anesthesia.
