Objective To study the effect of Shengmai injection on the platelet parameters and CD4+CD25+cells in peripheral blood of patients with chronic lymphocytic leukemia,and to explore the optimal regimen for patients with chronic lymphocytic leukemia.Methods One hundred and twenty patients with chronic lymphocytic leukemia were enrolled in this study from January 2012 to December 2014.(D1),vincristine 4mg(d1),prednisone 60 mg/d(d1-5)were given to the CHOP regimen in the control group: cyclophosphamide 600 mg/m2(d1),doxorubicin 25 mg/m2(d12)28d a course of treatment,a total of 4 courses,the observation group of patients in the control group of patients treated on the basis of Shengmai injection,compared the two groups of patients with chemotherapy,platelet parameters and serum CD4+CD25+T cells and Th17 cells.Results After treatment,the PLT,MPV and PDW of the observation group were(215.4± 31.7),(9.5±2.5)and(16.9±2.4),respectively,which were significantly higher than those of the control group.The CD4+CD25+T cells in the observation group were(1.5±0.8)The total effective rate of the control group was 35.0%,the total effective rate was 35.0%,and the total effective rate of the control group was 35.0%.There were significant difference between the control group and the control group(P<0.05),The difference was statistically significant.Conclusion Shengmai injection combined with CHOP regimen in chronic lymphocytic leukemia patients can improve immune function,promote platelet growth,improve platelet clinical parameters,and help improve the efficiency of chemotherapy,compared with CHOP alone Program treatment is better,worthy of clinical application.

OBJECTIVETo establish a method for the prenatal diagnosis of 22q11 microdeletion syndrome.
METHODSBACs-on-Beads (BoBs) and fluorescence in situ hybridization (FISH) were performed on a fetus for whom amniotic chromosomal culturing has failed and a pair of twin fetuses suspected for 22q11 deletion syndrome.
RESULTS22q11 microdeletion was detected in all 3 fetuses by prenatal BoBs as well as FISH, with only one red signal detected at the DiGeorge/VCFS N25 site and two green signals on the 22q13.3 ARSA site.
CONCLUSIONThe combination of prenatal BoBs and FISH can provide a method for the prenatal diagnosis of 22q11 microdeletion.

OBJECTIVE:
To analyze the prenatal ultrasonic characteristics and genetic features of 14 fetuses with chromosome 22q11 microdeletion syndrome (22q11DS).
METHODS:
4989 fetuses were analyzed by using single nucleotide polymorphism array (SNP array) in the Fujian Maternal and Child Health Hospital from November 2016 to November 2019.
RESULTS:
SNP array showed that 11 fetuses had classic 3 Mb microdeletion in 22q11 region, one fetus had 2.0 Mb microdeletion, and two fetuses had 1.0 Mb microdeletion. The 1.0 Mb microdeletion in 22q11 region contains SNAP29 and CRKL genes, which may increase the risk of congenital renal malformation and cardiovascular malformation.
CONCLUSION
Prenatal ultrasonic characteristics of fetuses with 22q11 microdeletion syndrome vary, and SNP array is a powerful tool to diagnose such diseases, which can provide accurate genetic diagnosis and enable prenatal diagnosis.

OBJECTIVE:
To analyze the intrauterine phenotype and genotype of eight fetuses carrying a 16p11.2 microdeletion.
METHODS:
5100 fetuses undergoing routine prenatal diagnosis were subjected to single nucleotide polymorphism-based microarray (SNP-array) analysis. Fetuses harboring a 16p11.2 microdeletion were analyzed for their ultrasonographic characteristics.
RESULTS:
Eight fetuses were found to harbor a microdeletion in the 16p11.2 region. Among these, six had a typical 500-600 kb deletion, while the remaining two had an atypical 220 kb deletion at the distal part of 16p11.2. Four fetuses showed vertebral malformations, two had mild left ventriculomegaly, one had hydrocephalus, and one had pulmonary valve stenosis with regurgitation. The parents of five fetuses have accepted pedigree verification, and the results confirmed that the 16p11.2 microdeletions carried by fetuses all had a de novo origin.
CONCLUSION
The intrauterine phenotypes of fetuses carrying a 16p11.2 microdeletion may be variable, and the deletion can be effectively detected with the SNP-array assay.

OBJECTIVE:
To analyze the ultrasonographic phenotype and result of genetic testing in six fetuses carrying a 17q12 microdeletion.
METHODS:
Chromosomal microarray analysis (CMA) was carried out for 6200 pregnant women undergoing prenatal diagnosis from December 2016 to May 2021.
RESULTS:
CMA has identified 6 fetuses with a microdeletion in the 17q12 region, which spanned approximately 1.4 Mb and encompassed at least 13 OMIM genes. All fetuses have shown bilateral renal parenchymal echo enhancement. Four fetuses also had other ultrasonographic phenotypes. The parents of 4 fetuses had refused parental verification, whilst the remaining two fetuses were confirmed to be de novo in origin.
CONCLUSION
The prenatal ultrasonographic phenotype of 17q12 microdeletion is mainly enhanced bilateral renal parenchymal echos. CMA can facilitate detection of the 17q12 microdeletion.
