1.Research updates on strabismus associated with congenital cataract
Chinese Journal of Experimental Ophthalmology 2021;39(4):346-350
Patients with congenital cataract often present strabismus simultaneously.Strabismus is closely related to the occurrence of cataract, and is one of the main threats for the development of binocularity and the therapeutic effect of amblyopia.In addition, strabismus negatively affects the appearance and psychological well-being of patients.The influencing factors of strabismus associated with congenital cataract include bilateral or unilateral congenital cataract, type of cataract, timing of cataract surgery, cataract surgery techniques, type of optical correction of aphakia and so on.Visual rehabilitation after congenital cataract surgery is inseparable from the treatment of strabismus.In this article, recent progress on the incidence, pathogenesis, influencing factors, timing of surgery and prognosis of strabismus associated with congenital cataract were reviewed, which might help to understand its clinical features and relevant treatment strategy.

The most common metastatic site of prostate cancer is the bone, followed by the lung, bladder, liver, and adrenal gland. We report on a rare case of pancreatic metastasis from prostate cancer. A 52-year-old patient was admitted to the hospital with epigastric pain for 20 days. PET-CT showed malignant lesions in the prostate and pancreas, and prostate and pancreas puncture biopsies were performed, respectively. The patient was diagnosed as prostate cancer with pancreatic metastasis according to the pathological findings. After undergoing androgen deprivation therapy and docetaxel chemotherapy for 6 cycles, reexamination revealed that the pancreatic metastases had disappeared.

Objective To investigate the impact of sample typeon the detection of c-KIT exon 17 mutation in acute myeloid leukemia (AML) patients. Methods A retrospective study was conducted on 51 bone marrow samples collected from 37 AML patients [17 maleand 20 female, with a median age of 33 (range from 1 to 82)] at diagnosis or after treatment from June 2016 to August 2018. Of the 37 cases of AML, 24 were t(8; 21) AML, 11 were inv(16)/t(16;16) AML and 2 were non-CBF-AML. RNA and DNA were simultaneously extracted from every sample. PCR followed by Sanger sequencing were used to screen c-KIT exon 17 mutation, and the comparisons were made between paired cDNA and DNAsamples. Results (1) Of the 51 paired samples, 14 pairs were simultaneously detected positive for c-KITmutation in both of cDNA and DNA samples, but 17 pairs were detected negative in both, and the remaining 20 pairswere only detected positive for the mutation in cDNA but not in DNA, with an inconsistency rate of 39.2%. The positive rate of detecting c-KITmutation was significantly higher in cDNA than in DNA samples (66.7%vs 27.5%,P=0.000073). (2)Inconsistent mutation results between paired cDNA and DNA samples occurred in t(8;21)AML, inv(16)AML and non-CBF-AML patients with the inconsistency rate of 36.4%(12/33), 27.2%(3/11) and 71.4% (5/7), respectively. (3)The inconsistency rate was significantly higher in samples collected after treatment compared with those collected at diagnosis (72.7%vs 13.8%, P=0.00003). (4) All 5 serially monitored patients with c-KITmutation had inconsistency in mutation detection between cDNA and DNA samples during follow up. Conclusion cDNA improves the detection of c-KIT exon 17 mutation in AML patients compared with DNA, which is especially common after treatment.

Objective:
To investigate the clinical significance of monitoring ETV6-RUNX1 fusion gene in children with acute lymphoblastic leukemia (ALL) after allogeneic stem cell transplantation (allo-HSCT) .
Methods:
Clinical data of 13 children received allo-HSCT in Peking University Institute of Hematology from May 2009 to March 2016 were retrospectively collected. The ETV6-RUNX1 gene was examined by real-time quantitative polymerase chain reaction (RQ-PCR) . The correlation between its expression level and the disease status was analyzed.
Results:
Of 13 enrolled ALL cases, the ETV6-RUNX1 expression of 7 patients converted to positive after transplant at a median time of 137 days (range, 28-270 days) . The expression level of the first positive sample was 0.034% (range, 0.004%-0.061%) . The duration from ETV6-RUNX1 positive to hematological relapse was 196 days (range, 28-666 days) . Four patients experienced relapse at a median time of 294 days (range, 104-803 days) after allo-HSCT. The ETV6-RUNX1 expression converted to positive prior to MRD. Patients with positive ETV6-RUNX1 gene expression pre-transplantation would be more likely to relapse.
Conclusion
Monitoring ETV6-RUNX1 by RQ-PCR could be used to evaluate MRD status after allo-HSCT. Patients with positive ETV6-RUNX1 after transplant had a poor prognosis.
