Objective To explore the relationship between metabolic syndrome(MS) and cerebral stroke type,complication and prognosis.Methods Clinical data of 568 cerebral stroke patients with MS(MS group) and 209 cerebral stroke patients without MS(no-MS group) were compared and analyzed.Results In MS group,the incidence of cerebral infarction was significantly higher(93.0%) than that in the no-MS group(85.2%)(P

Objective To analyze the second time blood screening results of ALT deferred donors,and to evaluate the importance of alanine aminotransferase(ALT) testing on the improvement of blood safety.Methods The ALT testing results of 565 360 blood donors from Feb.2006 to Jan.2008 of Shanghai Blood Center were studied retrospectively.The screening results and donation intervals of such donors who delayed their donation just because of their former unqualified ALT level were also analyzed.Results A total of 32 042 donors(5.67%) failed in ALT testing among 565 360 donors.And 3 395 ALT deferred donors participated the second time blood donation,among which 2 205(64.95%) passed the blood screening tests,while the other 1 190(35.05%) failed.Among the 1 190 unqualified blood donors,1 151(33.90%)failed again in ALT testing,and 11(0.32%) in Syphilis,12(0.35%) in HBsAg,7(0.21%) in anti-HCV and 1 in anit-HIV(0.03%).Meanwhile,donors failed both in ALT testing combined with HBsAg,anti-HCV,and anit-HIV sero-converted were 1(0.03%),2(0.06%) and 1(0.03%),respectively.And 72.64% of ALT deferred donors participated the second time blood donation within 6 months.The average donation intervals of donors with qualified ALT level but sero-converted were 140 days(from 24 to 267 days),and those with both unqualified ALT level and sero-converted were 158 days(from 91 to 220 days).Conclusion Before the new methods such as NAT were applied to blood donation screening system,ALT test could prevent the window-period failure of ELISA screening so as to improve the blood safety.

Objective: To compare setup errors between patients using the customized Klarity AccuCushion® with a thermoplastic fixation mask and patients using a thermoplastic fixation mask or vacuum fixation cushion alone while receiving radiotherapy. Methods: A total of 66 patients with head and neck (H&N) tumors (n=27) or thoracic and abdominal tumors (T&N) tumors (n=39) were included during Jaurnary 2018 to December 2019. 15 H&N cancer patients using only a single head-neck-shoulder mask were categorized into group A; 12 patients using a customized Klarity AccuCushion® and head-neck-shoulder mask were categorized into group B. Among T&A cancer patients, 19 patients using only a vacuum fixation cushion were classified into group A; the remaining 20 patients using a customized Klarity AccuCushion® and thermoplastic fixation mask were classified into group B. Cone-beam computed tomography was performed, and the setup errors were evaluated. The setup errors in the left-right (LR) direction, superior-inferior (SI) direction, anterior-posterior (AP) direction, and for rotation were compared between groups A and B. Results: Among H&N cancer patients, the setup errors in group B in the LR direction, SI direction, and for rotation were 0.06±0.06 cm, 0.08±0.07 cm, and 0.12±0.17°, respectively, which were smaller than those in group A (0.10±0.11 cm, 0.13±0.14 cm, and 0.25±0.47°, respectively). The differences in setup errors in the LR direction, SI direction, and for rotation were significant between the two groups (P<0.05), while no significant difference was found in setup errors in the AP direction (P>0.05). For T&A cancer patients, significant differences were found in setup errors between the two groups (P<0.05) in the LR direction (group B vs. group A: 0.10±0.08 cm vs. 0.14±0.12 cm) and for rotation (group B vs. group A: 0.09 ± 0.18° vs. 0.22 ± 0.39°). No significant differences were observed in the setup errors in the SI and AP directions. Conclusions: Compared with the immobilization techniques using only a thermoplastic mask and only a vacuumed fixation cushion, the technique using a customized Klarity AccuCushion® with a thermoplastic fixation mask can improve repeatability, stability, and setup errors in radiotherapy.

Objective To assess the prevalence of c-Kit and FLT3 gene mutations in core binding factor related acute myeloid leukemia (CBF-AML) and analyze the karyotype characteristics of the CBF-AML patients. Methods Mutations of c-Kit, FLT3-ITD and FLT3-TKD were detected by genomic DNA PCR and sequencing, and the karyotype changes were analyzed in 48 newly diagnosed CBF-AML patients. Results c-Kit aberrations were detected in 13(27.1 %) out of 48 patients, including 5 cases with exon 8 mutation and 8 cases with exon 17 mutation. c-Kit was more prominent in t(8;21) AML patients than in inv(16) AML patients [(33.3 %(9/27) vs 19.0 %(4/21), P<0.05]. Only 1 case (2.1 %) had FLT3-ITD mutation (FLT3-ITD+) and 3 cases (6.3 %) had FLT3-TKD mutation (FLT3-TKD +). Prevalence of RUNX1-RUNX1T1 with additional chromosome abnormality was as high as 25.9 %(7/27), in which sex chromosome elimination was the most common one, while prevalence of CBFβ-MYH11 with additional chromosome abnormality was low. Conclusion c-Kit gene mutations and RUNX1-RUNX1T1 additional chromosome abnormalities are common in patients with CBF-AML and would be helpful for individualized treatment studies.
