Clinical Anslysis of Primary Adrenal NK/T-Cell Lymphoma / 中国实验血液学杂志

OBJECTIVE@#To investigate the clinical characteristics, diagnosis, and treatment of one patient with primary adrenal natural killer/T-cell lymphoma (PANKTCL), and to strengthen the understanding of this rare type of lymphoma.@*METHODS@#The clinical manifestations, diagnosis and treatment process, and prognosis of the patient admitted in our hospital were retrospectively analyzed.@*RESULTS@#Combined with pathology, imaging, bone marrow examination， etc, the patient was diagnosed with PANKTCL (CA stage, stage II; PINK-E score 3, high-risk group). Six cycles of "P-GemOx+VP-16" regimen（gemcitabine 1 g/m2 d1 + oxaliplatin 100 mg/m2 d 1 + etoposide 60 mg/m2 d 2-4 + polyethylene glycol conjugated asparaginase 3 750 IU d 5） was performed, and complete response was assessed in 4 cycles. Maintenance therapy with sintilimab was administered after the completion of chemotherapy. Eight months after the complete response, the patient experienced disease recurrence and underwent a total of four courses of chemotherapy, during which hemophagocytic syndrome occurred. The patient died of disease progression 1 month later.@*CONCLUSION@#PANKTCL is rare, relapses easily, and has a worse prognosis. The choice of the "P-GemOx+VP-16" regimen combined with sintilimab help to improve the survival prognosis of patient with non-upper aerodigestive tract natural killer /T-cell lymphoma.

Progress of researches on mechanism of acupuncture for traumatic brain injury / 针刺研究

Acupuncture therapy has been shown to have a positive effect in treating symptoms of patients with traumatic brain injury (TBI) in China. The present paper summarizes findings of recent researches on the underlying mechanisms of acupuncture intervention for improving TBI from 1) inhibiting inflammatory response, 2) regulating neurotransmitters, 3) promoting nerve repair and regeneration, 4) antioxidation, 5) inhibiting intracellular calcium overload, 6) regulating aquaporin content, 7) regulating cellular energy metabolism, 8) improving brain circulation, and 9) inhibiting cell apoptosis.

Genetic distribution and forensic evaluation of multiplex autosomal short tandem repeats in the Chinese Xinjiang Mongolian group / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

To further enrich the genetic data of the Chinese Xinjiang Mongolian group, the genetic distribution and forensic parameters of 19 autosomal short tandem repeats (STRs) were investigated. Altogether, 249 alleles were observed in these 19 STRs. The mean values of the polymorphism information content (PIC), match probability (MP), discrimination power (DP), and probability of exclusion (PE) for these 19 STRs were 0.7775, 0.0699, 0.9301, and 0.6085, respectively. Additionally, the cumulative DP and PE values obtained in the Mongolian group were 0.999 999 999 999 999 999 999 995 67 and 0.999 999 992 163, respectively. Furthermore, population genetic analysis of the Mongolian group and 20 published populations was conducted based on the population data of 15 overlapping STRs. Genetic distances indicated that the Mongolian group had closer genetic similarities with the Uyghur, Xibe, and other Chinese populations rather than the other continental populations. Multidimensional scaling analysis further revealed that the Mongolian group possessed similar genetic distributions as most Chinese populations. To sum it all up, these STRs could be used as an extremely efficient tool for forensic applications in the Xinjiang Mongolian group.

Genetic Polymorphisms of 30 InDel Loci in Ewenki Ethnic Group from Inner Mongolia / 法医学杂志

OBJECTIVES@#To study the genetic polymorphisms of 30 insertion/deletion （InDel） loci and evaluate their forensic application in Ewenki ethnic group from Inner Mongolia.@*METHODS@#Peripheral blood samples were collected from 87 unrelated healthy individuals in Ewenki ethnic group. Genomic DNA were extracted, and 30 InDel loci of the samples were multiplex amplified and genotyped. Hardy-Weinberg balance tests were preformed for all loci and genetic parameters were calculated by modified PowerStats v1.2 software. The linkage disequilibrium between loci were tested by SNPAnalyzer v2.0 software. Based on the allele frequencies of 30 InDel loci, the genetic relationships between Ewenki ethnic group and other populations were evaluated by analysis of molecular variance, principal component analysis and phylogenetic reconstruction.@*RESULTS@#After correction, 30 InDel loci conformed to Hardy-Weinberg equilibrium. It was found that the pairwise InDel loci were in linkage equilibrium after Bonferroni correction. The results of population genetics indicated that Ewenki ethnic group had close genetic relationships with Henan Han and Beijing Han populations; whereas it was significantly different from several populations in Europe and Mexico.@*CONCLUSIONS@#There are relatively high genetic polymorphisms on 30 InDel loci of Ewenki ethnic group from Inner Mongolia, which can be used as a helpful supplement application for STR detection system.
