Objective To do analysis of sequence and identify a novel HLA-A allele in Chinese hematopoietic stem cell do-nors.Methods A rare HLA-A allele was initially detected by Luminex PCR-SSO typing,then the sample was sequenced by sequence-based typing (SBT)and the group-specific sequencing primer (GSSP)to confirm the mutation allele and locus.Re-sults The sequence of the sample results showed that the allele compared with the highest homologous allele HLA-A*24∶02∶01∶01 was the difference in the exon 3 at position 544 G>A,resulting in an amino acid sequence of HLA-A*24∶02∶01∶01 at position 158 change Ala to Thr.Conclusion This allele is a new HLA-A allele and has been designated as HLA-A*24∶327 by the HLA Nomenclature Committee of World Health Organization (WHO).

BACKGROUND:Induced pluripotent stem cel s have great prospects in tissue repair, due to the characteristic of self-renewal, multi-directional differentiation, no immunological rejection and ethics controversy.
OBJECTIVE:To summarize the differentiation of induced pluripotent stem cel s towards cardiomyocytes and endothelial cel s, and their applications in the cardiovascular diseases.
METHODS:The first author performed a data retrieval of PubMed and CNKI databases from 2000 to 2015 to search articles addressing the differentiation of induced pluripotent stem cel s towards cardiomyocytes and endothelial cel s, and reviewed the literatures systematical y. Final y, 78 articles were chosen for further analysis.
RESULTS AND CONCLUSION:Induced pluripotent stem cel s can differentiate into cardiovascular cel s through a variety of methods. Factors such as cyclosporin A and ascorbic acid C may improve myocardial differentiation of induced pluripotent stem cel s, while vascular endothelial growth factor and basic fibroblast growth factor may improve the endothelial differentiation of induced pluripotent stem cel s. Cardiovascular cel s derived from induced pluripotent stem cel s can be applied to build disease models in vitro, transplantation in vivo and drug screening.

OBJECTIVE: To evaluate the physical and mental health status of post-linguistic cochlear implantees, and then to explore the effectiveness on of different rehabilitation programs. METHOD: Mandarin hearing in noise test (MHINT), personal report of communication apprehension (PRCA-24) and Nijmegen cochlear implant questionnaire (NCIQ) were used to measure the hearing ability, mental health degree and the health related life quality in 36 post-linguistic cochlear implant users, respectively. The improvement of subjects' physical and mental health levels was compared with among different rehabilitation programs, including family training program, auditory habilitation program and psychological intervention program. RESULT: (1) Family training program only can improve the subject's hearing ability (P < 0.05), but failed to ease the communication apprehension; ((2) Auditory habilitation program can both significantly improve the subjects' hearing ability (P < 0.01) and ease the fear of talking face to face (P < 0.01); (3) Psychological intervention program can significantly increase the auditory abilities (P < 0.01), reduce the communication apprehension (P < 0.01) and improve the quality of life. CONCLUSION Post-linguistic cochlear implantees had obvious mental symptoms. It was very important to design an effective rehabilitation program to improvement the living quality of hearing loss people.

OBJECTIVE: To evaluate the mental health level of the post-linguistic deafen adult, to analyze factors affecting the mental health level. METHOD: Fifty-two adult patients with severe to extremely severe post-linguistic hearing loss were randomly selected to participate the study. A self-reporting questionnaire drew up by researchers was used to collect sociological data of the participants. The self-rating anxiety scale (SAS), self-rating depression scale (SDS) and personal report of communication apprehension (PRCA-24) were used to measure the mental health degree of 52 post-linguistic hearing loss adults. To analyze related factors affecting the mental health in post-linguistic deafen adult. RESULT: (1) Majority of post-linguistic deafen adult have mental symptoms, including 24 subjects (46.15%) with anxiety feeling, 18 subjects (34.61%) with depression feeling and 45 subjects (86.54%) with communication apprehension. (2) Gander, with/without tinnitus, duration of hearing loss, education background and family support had significant correlation with the mental health level of subjects. Higher incident rate of mental symptoms were found in male (OR = 2.246), with tinnitus (OR = 0.536), short duration (OR = 1.397, 1.530), high education background (OR = 0.323) and poor family support (OR = 1.724). CONCLUSION The mental health of the post-linguistic deafen adult was worse than that of the normal people, pathological feature and sociological factors were significantly correlated to the psychological evaluation. It is very important to pay attention on mental health and to give effective counseling of hearing loss people.

Objective:To study the expression of CXCL 8 in the serum and CXCL8 mRNA in the peripheral blood mononuclear cells(PBMCs) of the children with Mycoplasma pneumoniae pneumonia (MPP) and its clinical significance.Methods: Forty-eight children(severe cases 12,light cases 36) with MPP were recruited from October 2013 to March 2015 in the Maternal and Child Health-Care Hospital of Huainan.The concentration of the CXCL8 in serum and the level of CXCL8 mRNA in the PBMCs were measured by enzyme linked immunosorbent assay ( ELISA) and polymerase chain reaction ( PCR).Taking GAPDH as the internal reference ,the ratio of lgcDNA/lgGAPDH was regarded as the extreme level of CXCL 8 mRNA.Results: The serum level of CXCL8 and expression of CXCL8 mRNA in PBMCs in the children with MPP were ( 298.917 ±51.860 ) pg/ml and ( 1.848 ±0.525 ) lgcDNA/lgGAPDH.Compared with the normal control ,there were significant differences between the two groups ( P<0.05 ) .Further observation showed that the levels of CXCL8 in serum were no significant difference between in light cases and severe illness (P>0.05).However, the expression of CXCL8 mRNA in peripheral blood of the children with severe illness was significantly higher than those in light cases (P<0.05).Intravenous infusion of Erythromycin was provided in the acute phase for seven to ten days ,so that the children′s condition could be significantly controlled , and the symptoms of pulmonary inflammation were also relieved .Followed by the use of sequential therapy of Azithromycin for about two to three weeks ,the children′s condition were gradually from acute stage to recovery stage .At this time,the CXCL8 and its mRNA levels in peripheral blood of the sick children were all significantly decreased comparing with those in the acute stage(P<0.05).Conclusion: The expression of CXCL8 and its mRNA were increased in the peripheral blood of the sick children with Mycoplasma pneumonia ,and also correlated with the severity of the disease .CXCL8 can participate in the pathogenesis of Mycoplasma pneumonia ,and has a certain cue effect on the severity and prognosis of the disease .Azithromycin can reduce the content of CXCL8 in serum of the sick children via the pathway of inhibiting the proliferation of Mycoplasma pneumoniae ,and down regulate the expression of mRNA ,so that the immune injury mediated by Mycoplasma pneumoniae may be gradually inhibited .

Objective To observe the outcomes of fast track surgery program applied in thoracoscopic/laparoscopic esophagectomy.Methods From March 2010 to December 2012,99 esophagus cancer patients were randomly allocated to receive thoracoscopic/laparoscopic esophagectomy[minimally invasive esophagectomy (MIE) group,50 cases] and open esophagectomy [open esophagectomy (OE) group,49 cases].Same fast track surgery program was applied in both groups.Perioperative data of all patients were collected and analysized.Results The baseline of both groups was similar.Compared with OE group,MIE group got more abdominal lymph nodes resection,13(6-40) vs.4(0-20),P ＜0.05.In both groups,the level of the total albumin,hemoglobin and total cholesterol in the 8th postoperative day was higher than that of the 1 st postoperative day,P ＜0.05.Statistical difference was observed in the 48 h patient controlled analgesia usage,24 h and 48h visual analogue scales score of motion and less motion,postoperative creatine kinase level,the white cell count and C-reaction protein level in the 8th postoperative day,of which the MIE group got better results,P ＜ 0.05.Patients in MIE group took less time to begin oral nutrition (6 days vs.9 days P ＜ 0.05),besides,the parenteral nutrition duration [(7.9 ± 2.4) days vs.(8.6 ± 2.9)days,P ＜ 0.05] and postoperative hospital stay [(12.5 ± 3.1) days vs.(17.1 ± 6.3) days,P ＜ 0.05] were also shorter,P ＜0.05.Conclusion Fast track surgery program is safe and feasible for patients receiving esophagectomy.MIE combined with fast track surgery program can promote early rehabilitation by easing pain,reducing inflammatory response,improving nutrition state,lowering postoperative morbidity,shortening hospital stays,and as a result,have more obviously advantages.

Objective To investigate the effect of interferon-γ(IFN-γ) on the expression of indoleamine 2,3-dioxygenase(IDO),and tryptophanyl-tRNA-synthetase (TTS) in thyrocytes; and to study the relevant immunopathological significance in Graves' disease.Methods The expressions of IDO and TTS genes in IFN-γ stimulated Nthy-ori3-1 cell line and human thyrocytes,as well as in human thyroid tissues were determined by realtime quantitative PCR.Results IDO and TTS genes were expressed slightly in both Nthy-ori3-1 cell line and human thyrocytes,and were significantly up-regulated after IFN-γ stimulation(P＜0.01).Compared to healthy controls,TTS mRNA level was higher in thyroid tissues of patients with Graves' disease (P =0.018 2),while IDO mRNA level showed no difference,but was notably correlated with IFN-γ mRNA level (R2 =0.716,P =0.002).Conclusion In the early stage of Graves' disease,thyrocytes may decompose local tryptophan by enhancing the expression of IDO and TTS under IFN-γstimulation,thus inhibit auto-reactive function of lymphocytes and balance excessive autoimmune reaction.
