Objective To investigate serological blood typing of the ABO locus which contradict to general law of inheritance in parentage,and the underlying reasons for severe hemolytic disease of newborn(HDN).Methods To research the family whose newborn is AB phenotypes,mother is O phenotypes and father is AB phenotypes.The familiy were genotyped by parentage tests, serological tests,PCR-SSP and direct DNA sequencing at exons 6 and 7 of ABO gene.At the salne time,HDN was detected by micro column gel Coombs (MGCT), and the primary fingerposts of the routine blood tests. Biochemical tests were dynamically observed.Results The results of parentage tests showed that three-generation pedigree have parent-child relationship. The red blood cell(RBC)of this AB phenotypes of this family members strongly agglutinated(4+)with diverse monoelonal anti-A and anti-B antibodies,and their serum did not contain anti-A and anti-B antibodies in blood anti-typing.PCR-SSP can not detect their A and B gene,but DNA sequencing at exons6 and 7 of ABO gene revealed that it had the B(A)803C→G mutation.Conclusions The genetm basis of this parentage are B(A)803G blood gene which harbored both A and B difunctionality of glyeosyhransferases.This was the first report that severe HDN resulting from a large number of A and B antigens in RBC of B(A)phenotype of a newborn,which has clinical significance on ABO locus.

AIM:To study the effect of posterior sub - Tenon's capsule injection of triamcinolone acetonide ( TA ) in treatment of patients with diffuse diabetic macular edema ( DME) before panretinal photocoagulation ( PRP) .

AlM: To investigate the association between the degree of anterioruveitis and related factors including inflammatory markers as well as sacroiliac joint imaging in patients with ankylosing spondylitis ( AS) .
METHODS: Anterior changes evaluated by slit lamp, erythrocyte sedimentation rate ( ESR ) , C - reactive protein ( CRP ) and magnetic resonance imaging of 55 cases with AS associateduveitis were retrospectively analyzed. A modified endotoxin-induced uveitis ( ElU ) clinical standard was used for uveitis grading. SPARCC sacroiliac scoring was used to evaluate bone edema of sacroiliac joint. The correlation between the degree of uveitis and sacroiliitis was assessed.
RESULTS: ln the 55 patients with AS, ElU grading scored 2-10, and SPARCC index scored 0-22. Further analysis showed that the severity of uveitis was significantly correlated with ESR (r=0. 869, P<0. 001) and CRP (r=0. 485, P<0. 001). The degree of anterior uveitis in AS patients was not correlated with inflammation of sacroiliac joint (r=0. 237, P=0. 081).
CONCLUSlON: Local autoimmunity of uveitis and sacroiliac joint inflammation with subsequent bone formation in AS might be mutually independent processes.

Methods A total of 657 people of Hei Yi Zhuang nationality aged 40 years and over were surveyed. Blood pressure, body height, body weight, serum lipid and apolipoprotein levels were measured, and both body surface areas and body mass index were calculated. The results were compared with those in 520 people of Han nationality who also live in that district. Results The prevalence of hypercholesterolemia, hypertriglyceridemia, and hyperlipidemia in Hei Yi Zhuang vs. Han population were 28.9% vs. 35.8%(P0.05), and 36.2% vs. 42.3%(P0.05) respectively. Conclusions Prevalence of hyperlipidemia of Hei Yi Zhuang is lower than that of Han ethnic group, which might results from different dietary habit, life style, physical activity, and even genetic background.

OBJECTIVETo study the expressions of tumor necrosis factor alpha-induced protein 3(TNFAIP3) and mammary serine protease inhibitor (Maspin) in the radiotherapy of nasopharyngeal carcinoma and explore the differences in radiosensitivity and radioresistance,the relation with the occurrence and development of radioresistance.

METHODSThe TNFAIP3 and Maspin mRNA expressions were detected by using TNFAIP3 and Maspin multi-point labeled DIG probes in situ hybridization.

RESULTSIn radiosensitivity and radioresistance of nasopharyngeal carcinoma,the moderately and strongly positive TNFAIP3 mRNA expression rates were 27.50% and 48.33% (P=0.037), and the moderately and strongly positive Maspin mRNA expression rates were 67.50% and 46.67% (P=0.040). In the radioresistance of nasopharyngeal carcinoma,TNFAIP3 mRNA moderately and strongly positive expressions were positively correlated with TNM stage (P=0.005). In distant metastasis and no distant metastasis (70.00% and 37.50%, P=0.018), the expression rates had statistical significance. The Maspin mRNA moderately and strongly positive expressions were positively correlated with TNM stage (P=0.039) and T stage (P=0.021). In distant metastasis and no distant metastasis (65.00% and 37.50%, P=0.044), the expression rates had statistical significance.

CONCLUSIONTNFAIP3 may be involved in the development of radioresistant nasopharyngeal carcinoma,and Maspin may be related with the invasion and metastasis of radioresistant nasopharyngeal carcinoma.

Objective: To investigate the dynamic regulation of self-assembled aggregations (SAA) in Coptidis Rhizoma decoction on the permeability of intestinal tissue and the mechanism underlying. Methods: The effects of SAA on berberine (Ber) absorption were respectively analyzed in an in situ intestinal perfusion model and in an Ussing Chamber jejunum model with or without Peyer's patches (PPs). The expression levels of ZO-1, Occludin and Claudin-1 were detected by immunofluorescence to evaluate the tight junction (TJ) between intestinal epithelium cells. The expression levels of T-box-containing protein expressed in T cells, signal transducers and activators of tranion-6, retinoic acid receptor-related orphan receptor γt and forkhead box P3 in PPs were detected by the reverse transcription-polymerase chain reaction and the secretions of interferon-γ (IFN-γ), interleukin-4 (IL-4), interleukin-17 (IL-17) and transforming growth factor-β (TGF-β) in PPs were evaluated by immunohistochemistry, to reflect the differentiation of T lymphocyte in PPs to helper T (Th) cell 1, Th2, Th17 and regulatory T (Treg) cell. To confirm the correlation between SAA in Coptidis Rhizoma decoction, PPs-associated immunity and intestinal epithelium permeability, SAA were administrated on an Ussing Chamber jejunum model with immunosuppressed PPs and evaluated its influences on intestinal tissue permeability and TJ proteins expression. Results: SAA in Coptidis Rhizoma decoction could dose-dependently promote Ber absorption in jejunum segment, with the participation of PPs. The dose-dependent and dynamical regulations of SAA on permeability of intestinal tissue and TJ proteins expression level between intestinal epithelium cells occurred along with the dynamically changed T lymphocyte differentiation and immune effectors secretion in PPs. The administration of SAA on immunosuppressed PPs exhibited dose-dependent PPs activation, inducing dynamic promotion on intestinal tissue permeability and inhibition on TJ proteins expression. Conclusion: SAA can improve the Ber absorption in small intestine, through the PPs-associated immunity induced dynamic regulation on intestinal tissue permeability and TJ proteins expression. These findings might enlighten the research of traditional Chinese medicine decoction.

PURPOSE: The universal organic solvent dimethyl sulfoxide (DMSO) can be used as a differentiation inducer of many cancer cells and has been widely used as a solvent in laboratories. However, its effects on breast cancer cells are not well understood. The aim of this study is to investigate the effect and associated mechanisms of DMSO on mouse breast cancer. METHODS: We applied DMSO to observe the effect on tumors in a mouse breast cancer model. Tumor-associated macrophages (TAMs) were tested by flow cytometry. Ex vivo tumor microenvironment was imitated by 4T1 cultured cell conditioned medium. Enzyme-linked immunosorbent assays were performed to detect interleukin (IL)-10 and IL-12 expression in medium. To investigate the cytotoxicity of DMSO on TAMs, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays were performed. RESULTS: We found that DMSO produced tumor retardation when injected into mouse peritoneal cavities in a certain concentration range (0.5-1.0 mg/g). Furthermore, as detected by flow cytometry, TAM subtypes were found to be transformed. We further imitated a tumor microenvironment in vitro by using 4T1 cultured cell conditioned medium. Similarly, by using low concentration DMSO (1.0%-2.0% v/v), TAMs were induced to polarize to the classically activated macrophage (M1-type) and inhibited from polarizing into the alternatively activated macrophage (M2-type) in the conditioned medium. IL-10 expression in tumors was reduced, while IL-12 was increased compared with the control. Furthermore, we reported that 2.0% (v/v) DMSO could lead to cytotoxicity in peritoneal macrophages after 48 hours in MTT assays. CONCLUSION: Our findings suggest that DMSO could exert antitumor effects in 4T1 cancer-bearing mice by reversing TAM orientation and polarization from M2- to M1-type TAMs. These data may provide novel insight into studying breast cancer immunotherapy.
