Objective:To investigate the expression of immunoglobulin A (IgA) in human mesangial cells (HMCs).Methods:The HMCs were cultured.The subcellular location of IgA was detected by immunofluorescence staining;the transcripts of Ig α,Ig κ and Ig λ constant region were detected by reverse transcription-polymerase chain reaction (RT-PCR) and further analyzed by DNA sequencing.The expressions of Igαt and Ig λ were detected at transcription level by Western blot after the cytoplasmic protein extraction.The culture supernatant was collected to explore whether IgA could be secreted out of the cell and the protein was further analyzed by mass spectrometry after being purified by affinity chromatography with jacalin-sepharose.The results of DNA sequencing and mass spectrometry were aligned with the mRNA and amino acid sequences in the National Center of Biotechnology Information (NCBI) data-base.Results:By immunofluorescence staining,we detected the presence of IgA heavy chain Ig α,light chain,both Ig κ and Ig λ in expressions of transcripts of Ig α1,Ig α2,Ig κ and Ig λ in the HMCs and the alignment of the sequences of the RT-PCR products with those of the Ig Cα1,Ig Cα2,Ig κ and Ig λ mRNA in the NCBI database exhibited that the similarities were 99％,97％,98％ and 97％,respectively.Western blot showed Ig α and Ig λ expressions in the cell lysate and secretion of Ig α1 and Ig α2 heavy chains in cell culture supernatant.To further explore the protein that secreted into the supernatant,after supernatant affinity chromatography with jacalin-sepharose,the proteins were separated by sodium dodecyl sulfonate-polyacrylamide gel electrophoresis (SDS-PAGE) and the band approximating to 65 000 was cut and sent to mass spectrometry.The results were aligned with the amino acid sequences of Ig α1 and Ig α2 constant region in NCBI database,showing that amino acids between No.52 and No.104,amino acids between No.154 and No.221,amino acids between No.276 and No.327 from Ig Cα1 and amino acids between No.52 and No.113,amino acids between No.151 and No.204,amino acids between No.251 and No.314 from Ig Cα2 were the same with those derived from B cells.Conclusion:Our findings suggested that HMCs could synthesize and secret IgA.

OBJECTIVETo investigate the distribution of abnormal hilit syndromes in traditional Uighur medicine (TUM) among human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) patients, and to find out the clinical characteristics of abnormal savda syndrome type HIV/AIDS patients.

METHODSBetween June and July in 2012, 307 eligible HIV/AIDS patients from in-patient department and out-patient clinics of Xinjiang Uighur Autonomous Region the Sixth People's Hospital in Urumqi were investigated. TUM syndrome differentiation was performed by a senior TUM physician. Each participant completed a Sign and Symptom Check-List for Persons Living with HIV/AIDS (SSC-HIV) questionnaire. Depression was evaluated by using Hamilton Rating Scale for Depression Questionnaire. Blood specimen was collected from each participant to test the levels of blood chemicals.

RESULTSOf 307 HIV/AIDS patients, 189 (61.6%) were abnormal savda syndrome type, 118 (38.4%) were non-abnormal-savda syndrome type. Mean CD4 counts of abnormal savda syndrome type patients was (227.61±192.93) cells/µL, and the prevalence of anemia, thrombocytopenia, and elevated cystatin C were 49.7%, 28.6%, and 44.7%, which were significantly higher than those in the non-abnormal-savda syndrome type patients (26.3%, 16.0% and 25.0%,P<0.05). In addition, depression (79.9%) and HIV/AIDS-related symptoms such as fatigue (42.3%), back aches (40.7%), lack of appetite (33.9%), night sweats (31.7%) were more common among abnormal savda syndrome patients (P<0.05).

CONCLUSIONAbnormal savda syndrome is the dominant syndrome among HIV/AIDS patients, and they present a more sever clinical manifestation.

OBJECTIVE: To investigate the function of RAS protein on the progression of the T-ALL cell lines in vitro. METHODS: The DNA of the T-ALL cells was purified then amplified the coding regions of three RAS genes (KRAS, NRAS, HRAS) by PCR reaction. After T-A cloning, the coding regions of KRAS, NRAS and HRAS were sequenced by Sanger Sequencing. The siRNA oligonucleotides were cloned into the pSEH-361 vector, which were then packaged into retroviral together with pAMPHO and pVSVG in the HEK-293T cells. The T-ALL cells were infected with the retrovirus. The gene expressions were detected by qRT-PCR and Western blot. The T-ALL cells were stained with Annexin V-PE/7-AAD and the apoptotic cells were detected by flow cytometry. The T-ALL cells were stained with Hoechst 33258, and the cell cycle distribution was determined by flow cytometry. The expression of cleaved-Caspase 3 was stained with antibody and observed with fluorescence microscope. RESULTS: For RAS genes, beside the Loucy and the P12-ICH cells harbored KRAS c.6187G>A (p.KRAS^G12D) homozygous mutant, no missense mutation of RAS was found in other T-ALL cells genome. The pan RAS inhibitor compound 3144 showed toxicity to all tested T-ALL cells, except PEER (IC₅₀=47.916 μmol/L). Similarly, Tipifarnib induced apoptosis of multiple T-ALL cell lines except for the PEER cells (IC₅₀=94.2265 μmol/L). After KRAS knock-down, the T-ALL cells showed significant apoptosis and an arrested cell cycle. CONCLUSION The KRAS protein is vital for the progression of the T-ALL cells in vitro, it is a potential therapeutic target for T-ALL patients.

The mammalian epididymis not only plays a fundamental role in the maturation of spermatozoa, but also provides protection against various stressors. The foremost among these is the threat posed by oxidative stress, which arises from an imbalance in reactive oxygen species and can elicit damage to cellular lipids, proteins, and nucleic acids. In mice, the risk of oxidative damage to spermatozoa is mitigated through the expression and secretion of glutathione peroxidase 5 (GPX5) as a major luminal scavenger in the proximal caput epididymidal segment. Accordingly, the loss of GPX5-mediated protection leads to impaired DNA integrity in the spermatozoa of aged Gpx5
