Objective To describe the status of adherence to antiretroviral therapy (ART) in low endemic area,and to explore the factors affecting ART adherence so as to provide evidence for behavior management program.Methods A cross-sectional study was conducted in 53 patients receiving free ART in Chuanying and Yongji of Jilin Province.Structured face-to-face interview was carried out to determine sociodemographic characteristics,medical treatment information,medication adherence behaviors,health belief and self-efficacy,doctor-patient relationships and health service information.Results Among 53 patients,3 reported drug discontinuance.Of the other 50 patients,41 (82.0％) obeyed the request of the doctors (to be defined as adherence).All the participants had high levels of perceived benefits of adherence,perceived severity of non-adherence and self-efficacy.94.3％ of them reported using medication reminders,88.7％ reported receiving directly observed therapy (DOT),and 73.6％ reported falling into the habit of drug administration.Conclusions HIV/AIDS patients show relatively good adherence to medical treatment.Local comprehensive education and supportive programs may contribute to patients' good adherence to ART.

Alveolar soft part sarcoma (ASPS) is a kind of extremely rare malignant soft tissue sarcoma, which was first discovered and defined by American scholars in 1952. Its main manifestation is painless and slow growth mass, and distant metastasis often occurs in lung, bone, brain, liver with poor prognosis. In recent years, with the accumulation of the number of cases and the development of related technology, the diagnosis and treatment of ASPS have been improved greatly. However, the primary intracranial ASPS is still rare, this paper reviews the progress of primary intracranial ASPS, in order to provide help for its clinical diagnosis and treatment.

Objective To investigate the protective effect of genistein on endotoxin-induced acute lung injury in rats,and explore the underlying mechanisms.Methods Thirty-two male Sprague-Dawley rats were randomly divided into four experimental groups: saline control(S), genistein alone(G),lipopolysaccaride(LPS) alone(L),and genistein pretreatment(G+L).Each treatment group consisted of eight animals.Animals were observed for 6h after LPS challenge,and the wet/dry(W/D) weight ratio of the lung and the protein contents of the bronchoalveolar lavage fluid(BALF) were used as indexes of lung injury.Neutrophil recruitment and activation were evaluated by BALF cellularity and myeloperoxidase(MPO) activity.RT-PCR analysis was performed with lung tissue to assess the gene expression of ICAM-1.The histopathologic changes were also observed using the H&E stains of lung tissue.Results Lung injury parameters,including the wet/dry weight ratio and protein content in BALF,were significantly higher in the L group than in the S group(P

Objective To study the relationship of soluble LAIR (sCD305 and CD3060) expression in recipient serum with cytomegalovirus (CMV) pneumonitis after renal transplantation. Methods Nineteen serum specimens from recipients were divided into CMV pneumonitis group (n=10) and control group (n=9). Then the concentrations of sCD305 and CD3060 were quantitated with sandwich ELISA. The data were analyzed by using student t test. Results sCD305 was skewness distributed in both 2 groups, was 0.000-3.039 μg/L in CMV pneumonitis group and 0.000-8.375 μg/L in con-trol group. CD3060 was skewness distributed in CMV pneumonitis group and the concentration was 0.000-0.017μg/L. CD3060 was mormally distributed in control group and the concentration was 0.046±0.035 μg/L. There was significant difference of CD3060 (P=0.000) concentrations and no sig-nificant difference of sCD305(P=0.316) concentrations in 2 groups, respectively. Conclusions The concentration of CD3060 is low in CMV pneumonitis patients. The combination of CMV PP65 antigen detection and CD3060 detection is helpful for the early and precise diagnosis of CMV pneumonitis in renal transplantation patients.

OBJECTIVE To study characteristics of changing T lymphocytes in epidemic hemorrhagic fever(EHF) patients during acute phase and find out the pathogenesis,in order to elevate the level of early diagnosis.METHODS The anticoagulant blood from 30 cases of EHF patients and 50 normal healthy blood donors was collected.T lymphocyte subsets were detected by flow cytometry.RESULTS Compared with those of normal persons,CD4+ T cell counts of EHF patients decreased,CD8+T cell and double CD4+CD8+ cell(double positive cells,DP cell) counts of EHF patients increased obviously,and 25 cases of EHF in recovery stage returned to normal.And in comparison with HIV,CMV and EBV patients,DP cell counts of EHF patients increased obviously.CONCLUSIONS T lymphocytes of EHF decrease obviously but could be resumed,detection of amounts of lymphocyte subsets and CD4+CD8+ cells can provide an early diagnosis method to EHF.

[ ABSTRACT] AIM:To evaluate the effects of 1α, 25-dihydroxyvitamin D3 on T helper cell 17 ( Th17 cells) and its related cytokines in a mouse model of corneal allograft transplantation.METHODS:C57BL/6 mice were transplanted with corneal grafts from BALB/c mice and treated intraperitoneally with 1.0μg 1α, 25-dihydroxyvitamin D3 or soybean oil every other day after operation.The transparency of the corneal grafts was evaluated for potential rejection signs by slit lamp biomicroscopy and histopathology.The expression levels of IL-17, RORγt and IFN-γin the spleen were measured by real-time PCR.Moreover, the protein expression of RORγt and IL-17 in the peripheral blood was analyzed by Western blotting. IL-17 and IFN-γin peripheral blood were measured by flow cytometry.RESULTS:1α, 25-dihydroxyvitamin D3 signifi-cantly inhibited the rejection of the corneal allograft and reduced the numbers of inflammatory infiltrates in the corneal graft. In the spleen, 1α, 25-dihydroxyvitamin D3 treatment reduced the expression levels of IL-17, RORγt and IFN-γ.In the pe-ripheral blood, 1α, 25-dihydroxyvitamin D3 treatment downregulated the expression levels of RORγt, IL-17 and IFN-γ. CONCLUSION:The effects of 1α, 25-dihydroxyvitamin D3 on suppressing corneal transplantation-induced allograft rejec-tion in mice are closely associated with its modulation on IL-17 and related cytokine RORγt.

UNLABELLEDOBJECTIVE To investigate an operative method of combined resection of preseptal fat: and partial retro-orbicularis oculus fat (ROOF) for correction of upper eyelid heaviness, and evaluate the efficacy and safety of the method.

METHODSPreseptal fat lies widely under the orbicularis oculi in the upper eyelid, and retro-orbicularis oculus fat (ROOF) lies in the lateral supraorbital area. Combined resection of preseptal fat and partial ROOF was performed in patients selected by examination. The efficacy and safety were evaluated by follow-up study.

RESULTSFrom May 2011 to July 2013, 38 selected patients received the treatment with 3 months to 28 months follow up. The heaviness of upper eyelid improved in all cases. One patient developed postoperative hematoma, and another patient had a transient numbness over the lateral upper brow region. 37 patients were satisfied with the result.

CONCLUSIONSCombined resection of preseptal fat and partial ROOF was effective in reducing the heaviness of upper eyelid, without major complications. The operative method should be an important adjunct for selected patients undergoing blepharoplasty.

BACKGROUND:Cytotoxic T lymphocyte-associated antigen 4 is a newly discovered costimulatory molecule. It has been studied more in tumor and autoimmune diseases, less in the field of kidney transplantation.
OBJECTIVE:To explore the role of cytotoxic T lymphocyte-associated antigen 4 in acute rejection after renal transplantation.
METHODS:Fifty patients undergoing renal transplantation were divided into acute rejection group (20 cases) and stable graft function group (30 cases). Another 30 healthy persons served as control group. Blood samples were extracted from the peripheral blood. Cytotoxic T lymphocyte-associated antigen 4 was detected by enzyme linked immunosorbent assay and flow cytometry.
RESULTS AND CONCLUSION:The expression of cytotoxic T lymphocyte-associated antigen 4 in the serum showed significant differences in the acute rejection group, stable graft function group and healthy control group (F=70.008 1, P=0.000 0), but showed no difference in peripheral blood lymphocytes of three groups (F=1.865 6, P=0.161 7). Compared with the healthy control group, the expression levels of cytotoxic T lymphocyte-associated antigen 4 in peripheral blood lymphocytes of acute rejection group and stable graft function group were significantly decreased (P=0.000 0). In addition, the acute rejection group had a lower cytotoxic T lymphocyte-associated antigen 4 expression than the stable graft function group (P=0.000 0). In renal transplant rejection, the expression of cytotoxic T lymphocyte-associated antigen 4 in serum was reduced, showing some correlation with acute rejection after renal transplnatation. Cytotoxic T lymphocyte-associated antigen 4 might be involved in the rejection.
