1.Integration of Micro Sensors with Mobile Devices for Monitoring Vital Signs of Sleep Apnea Patients.
Chinese Journal of Medical Instrumentation 2019;43(1):29-31
This paper demonstrates a BSN-based portable monitor integrating micro sensors with mobile devices for monitoring and diagnosing obstructive sleep apnea syndrome (OSAS) at home. The system uses a micro hot-film flow sensor to detect respiratory flow, uses tri-axis micro accelerometer to detect body posture and motion intensity, and uses a micro photoelectric sensor to detect oxygen saturation of blood. The real-time vital signs are detected and transmitted wirelessly to a mobile device. The transmitted data are processed and analyzed in the mobile device and can be further transmitted to a remote medical center and physicians through mobile cellular networks or Internet for comprehensively analyzing, assessing, and diagnosing to the diseases.

OBJECTIVE:
To explore the genetic basis of three children with unexplained mental retardation/developmental delay.
METHODS:
Peripheral venous blood samples were collected for routine G-banding karyotyping analysis and chromosomal microarray analysis (CMA). Whole exome sequencing (WES) was also carried out for patient 3.
RESULTS:
The karyotypes of the 3 children were normal. The result of CMA analysis of patient 1 was arr[GRCh37]: 2q22/3(145 128 071-145 159 029)×1, with a 31 kb deletion, which was predicted to be a pathogenic copy number variation. The deletion has involved exons 8 to 10 of the ZEB2 gene. Patient 2 was arr[hg19]:2q22.3 (145 071 457-146 881 759)×1, with a 1.81 Mb deletion involving the ZEB2 and GTDC1 genes. Patient 3 was arr[GRCh37]: 9p23p23(11 698 261-12 106 261)×1, with a 408 kb deletion containing no disease-associated gene. WES has identified a c.2102C>A (p.Ser701*) variant in exon 8 of the ZEB2 gene, which was included in ClinVar database and rated as pathogenic, and verified by Sanger sequencing as a de novo variant.
CONCLUSION
For the substantial clinical and genetic heterogeneity of Mowat-Wilson-syndrome, CMA and WES are helpful to identify the etiology of children with developmental delay/mental retardation of unknown causes, particularly those with peculiar facial features and multiple congenital malformations.

OBJECTIVE:
To analyze the genotype and clinical phenotype of a 3-month-old female infant featuring unresponsiveness.
METHODS:
The infant was subjected to genetic testing, and her clinical features were compared with syndromes associated with variants of the candidate gene.
RESULTS:
The patient has featured long fingers, long and overlapped toes, musk-like face, blepharophimosis, ptosis, and lacrimal duct anomaly. She was found to harbor a heterozygous de novo variant NM_012330.3: c.3040C>T (p.Gln1014*) in exon 16 of the KAT6B gene. Her clinical phenotype and genotype have both conformed to Say-Barber-Biesecker-Young-Simpson syndrome (SBBYSS).
CONCLUSION
The child was diagnosed with SBBYSS syndrome due to the c.3040C>T (p.Gln1014*) variant of the the KAT6B gene. Discovery of the unique features has expanded the phenotypic spectrum of this syndrome.

Based on a non-competitive and selective PTP1B inhibitor reported by us previously, thirty-nine benzamido derivatives were designed and synthesized as novel PTP1B inhibitors. Among them, twelve compounds exhibited IC values at micromolar level against human recombinant PTP1B, and most of them exhibited significant selectivity to PTP1B over TC-PTP and CD45. Further evaluation of the most potent compound on high-fat diet (HFD)-induced insulin-resistant (IR) obese mice indicated that could modulate glucose metabolism and ameliorate dyslipidemia simultaneously.
