【Objective】 To study the genotypes of ABO ambiguous blood group samples(n=20) and identify their molecular biological characteristics. 【Methods】 The serological phenotype of the samples was analyzed by serological techniques. Seven exons of ABO gene were amplified by polymerase chain reaction (PCR) and the PCR products were directly sequenced; the genotypes and sequences of ABO subtypes were analyzed. 【Results】 The serological phenotypes of 20 samples presenting ABO ambiguous blood group were as follows: weak A antigen (n=5), weak A antigen combined with anti-A1 antibody (n=5), normal A antigen combined with anti-A1 antibody (n=2), weak B antigen (n=8). The genotypes of them were as follows: Ax02/O01 (n=3), Ael07/O01 (n=2), B313/O01 (n=2), A204/O02 (n=1), A220/O01 (n=1), Ael07/O02 (n=1), Ael02/O01 (n=1), Ael02/O02 (n=1), Ax03/O01 (n=1), Ax03/O02 (n=1), B313/O02 (n=1), B302/O01 (n=1), B302/O02 (n=1), Bw19/O02 (n=1), A102/B313 (n=1) and A101/Bw37 (n=1). 【Conclusion】 ABO genotyping technology can accurately identify the ambiguous blood group of samples, provide definite genetic information of blood group and ensure the safety of clinical transfusion.

Genetic background can lead to differences in drug effects among different populations when they use the same drug. To delineate the pharmacogenomics and population genetic differences may help to clarify the role of polymorphisms of drug metabolism-related genes in drug effect heterogeneity among different populations. This article has summarized the latest progress on the polymorphisms of drug metabolism-related genes among different populations in China.

Genetic factors play a key role in human athletic ability, and endurance quality and explosive power quality are the important components of athletic ability. In this review, we aimed to reveal the biological genetic mechanism of human athletic ability at the molecular level through summarizing the relationship between genetic variants and human athletic ability, including endurance quality related genetic markers angiotensin converting enzyme (ACE) gene, creatine kinase MM (CKMM) gene and explosive power quality related genetic markers alpha actinin 3 (ACTN3) gene, angiotensinogen (AGT) gene and interleukin6 (IL6) gene. Meanwhile, we also summarized the distribution of allele frequencies among various populations.

Objective: To establish colorectal cancer LoVo and SW620 cell lines that stably interfere with the expression of LINC01224, and to explore the effect of down-regulating the expression of LINC01224 on cell apoptosis. Methods: The GEPIA2 database was used to analyze the expression of LINC01224 in colorectal cancer tissues; qPCR method was used to detect the expression of LINC01224 in 10 human colorectal cancer cells. Three different LINC01224 siRNAs were respectively transfected into human colorectal cancer LoVo cells, and the LINC01224 shRNA lentiviral vector was constructed with the siRNA sequence with the most obvious inhibitory effect of LINC01224 expression. Recombinant lentiviral particles were packaged in HEK293 T cells and then infected with LoVo and SW620 cells. After selection by puromycin, the monoclonal cells that stably interfere with LINC01224 were obtained by limiting dilution method. MTS method detects cell proliferation ability, and flow cytometry detects cell apoptosis rate. Results: The expression of LINC01224 in colorectal cancer tissues was higher than that in normal colorectal tissues, and its expression in 10 types of colorectal cancer cells was also higher than that in normal colorectal epithelial cells HCOEPic. The inhibition rate of siRNA-3 on the expression of LINC01224 in LoVo cells was higher than that of siRNA-1 and siRNA-2. Therefore, siRNA-3 was chosen to design LINC01224 shRNA.Compared with the control group(sh-NC group), the expression level of LINC01224 in the LoVo and SW620 cells of the stable interference LINC01224 group(sh-LINC01224 group) was reduced(P<0.01), and the cell growth rate was slowed down(P<0.01), the rate of apoptosis also increased(P<0.01). Conclusion The shRNA lentiviral interference vector of LINC01224 is successfully constructed, which can stably infect LoVo and SW620 cells, down-regulate the expression of LINC01224 and induce cell apoptosis.

A 53-year-old man was admitted to the hospital for verrucous hyperplasia on the circular sulcus for 2 years as well as erythematous painful swelling, ulcer and rupture of inguinal lymph nodes for more than 2 months. Physical examination revealed erythematous, indurated and painful swelling of bilateral inguinal lymph nodes. Fluctuation could be felt at the centre of the right swollen inguinal lymph nodes, where several pores were seen with yellowish-white purulent fluid flowing out, giving the appearance of a watering can. Multiple swollen or ulcerative lymph nodes were separated by the inguinal ligament forming the groove sign.There were irregular, indurated, verrucous, proliferative and keratinized lesions sized 1 cm × 2 cm on both sides of the circular sulcus. The right scrotum was obviously swelling. Erythematous, fluctuating swelling, ulcer and rupture of the glans fraenum were also observed with yellowish-white purulent exudates. Neither the secretion from the skin lesions on the surface of bilateral inguinal lymph nodes nor the puncture sample from the right groin was positive for multiple fungal or bacterial culture, acid-fast stain or first culture of C. trachomatis.However, the endogenous plasmid of Chlamydia was successfully amplified by PCR from these samples, and restriction fragment length polymorphism (RFLP) analysis of the major outer membrane protein (MOMP) suggested that the genotype of the Chlamydia strain was L3. Western blot revealed the presence of anti-MOMP antibodies and anti-Pmp H antibodies (titer: ＞ 1: 800) in serum. Culture of C. trachomatis also gave positive results after multiple passage. Biopsy of the verrucous hyperplasia on the right groin is consistent with well-differentiated squamous cell carcinoma of the skin. A diagnosis of lymphogranuloma venereum complicated by cutaneous squamous cell carcinoma was made.
