The effect of rosiglitazone and advanced glycation end products (AGEs) on the expression of fractalkine in cultured human renal mesangial cells (HRMC) were investigated. Rosiglitazone inhibits the upregulation of fractalkine induced by AGEs in HRMC.

AIM:To study whether or not Huangshao Yinxue Granula(HYG) has the therapeutic effect on experimental psoriasis. METHODS: The mice were treated with HYG 3.125,6.25,12.5,and 25 g/kg(i.g.) for 1 or 2 weeks.We studied the effects of HYG on mitosis in mice vagina epithelium,the formation of granular layer in scale epidermis of mice tails,the changes in CD3, CD4 and CD8 factors of the serum in psoriasis-like mice and guinea-pigs. RESULTS: HYG could inhibit the mitosis in mice vagina epithelium,promote the formation of granular layer in scale epidermis of mice tails.It could also diminish the value of serum CD4/CD8 of mice to regulate abnormal immune reaction.HYG had evident therapeutic effect on the ear skin damaged with 5% propanolol in psoriasis-like guinea-pigs. CONCLUSION: HYG has therapeutic effect on psoriasis-like animal models.

Objective To investigate the functional characteristic of adolescents with conduct disorder (CD) in the resting state.Methods Resting-sate fMRI (rs-fMRI) scans were administered to 28 male adolescents with CD and 28 age-,gender-and IQ-matched healthy controls (HCs).The rs-fMRI data were subjected to amplitude of low-frequency fluctuation (ALFF) analysis and ALFF values were compared between the two groups.Additionally,the region ROIs showed significant difference and correlation analysis was conducted between ALFF in each ROI and Barratt's scores.Results ① Compared to HCs,the CD group showed decreased ALFF (P＜0.005) bilaterally in the superior frontal gyrus,right middle frontal gyrus,right posterior cingulate gyrus,right inferior parietal lobule (MNI coordinates:-21,48,27;21,24,48;36,24,33 6,-36,39;48,-45,57 respectively) as well as increased ALFF (P＜O.005) in the left thalamus and left lingual gyrus (MNI coordinates:-15,-27,-3;-18,-87,-12 respectively).② There was no significant correlation between ALFF and Barratt's scores in ROIs.Conclusion The results suggest that CD is associated with abnormal intrinsic brain activity,mainly in frontal-parietal-occipital-limbic cortices,which is related to emotional and cognitive processing and behavioral functions.

Immunoglobulins ( Ig ) , also called antibodies, are important components in humoral -mediated immunity. Ig can bind with their receptors, called immunoglobulin receptors ( IgR ) , trigger biologic activities respectively. Different sub-types of Igs show different function. And IgRs have been treated as therapeutic targets in inflammation and immunity related dis-eases for many years. This article reviewed the recent progresses in the study of IgR function and its therapeutic role in inflamma-tion and immunity related diseases.

BACKGROUND: In clinical, the research on the method and the material of the soft tissue defect of the operation area has been in depth. It wil have a positive impact on our exploration and research in this field through the establishment of reliable experimental animal oral soft tissue defect model. OBJECTIVE: To establish a rabbit model of oral soft tissue defects for oral treatment of soft tissue defects in-depth study. METHODS: Eighteen 3-month-old male New Zealand rabbits were enrol ed. A tissue ring cutting dril of 5 mm diameter was used to prepare round ful -thickness soft tissue defects in the front part of the hard palate and, respectively, from the back of the maxil ary incisors, about 2 mm from the hard palate mucosal edge. Morphology and histology were observed at 3, 7, 14, 21, 28 and 56 days after model establishment. RESULTS AND CONCLUSION: (1) Morphological observation: After 3 and 7 days, the wound’s inflammatory reaction was obvious. As the time goes, the inflammatory response subsided, the wound gradual y healed. Scar formation was observed at 21, 28 and 56 days after surgery. (2) Histological observation: 3 and 7 days after injury, many inflammatory cel s were infiltrating, and tissue necrosis area was larger. At 7 days after surgery, with the extensive formation of connective tissue proliferation and new blood capil aries, the wound gradual y shaping completely. (3) Results indicated that a rabbit model of oral soft tissue defects was successful y established, which was in line with the physical laws of wound healing and the characteristics of human oral soft tissue defects healing.

BACKGROUND:Previous studies have found that platelet-rich fibrin has a good ability to induce gingival soft tissue repair and regeneration.
OBJECTIVE:To observe the effects of platelet-rich fibrinversus colagen membrane on gingival soft tissue healing, and to evaluate the ability of platelet-rich fibrin to repair gingival defects.
METHODS:Twenty-two patients (2 premolar teeth and 20 molars) scheduled for premolar or molar removal or ridge preservation due to various reasons were selected and randomized into two groups. Bio-Oss was implanted into the extraction socket folowed by covering with platelet-rich fibrin or colagen membrane. Healing time and healing rate of gingival defects were detected to evaluate the ability of platelet-rich fibrin to promote gingival tissue healing at 1-2 weeks after Bio-Oss implantation.
RESULTS AND CONCLUSION:The healing time was (12.17±2.25) days in the platelet-rich fibrin group and (17.30±2.58) days in the colagen group. The healing rate of the platelet-rich fibrin group was notably higher than that in the colagen membrane group at 1 and 2 weeks after Bio-Oss implantation. These findings indicate that platelet-rich fibrin is better than colagen membrane to improve the healing of gingival soft tissues with a shorter healing time.

Objective To investigate the clinical efficacy and safety of the cytokine-induced killer cells (CIK) treated in patients with advanced pancreatic cancer. Methods 74 cases (hospitalized from January 2012 to December 2013) with advanced pancreatic cancer (Ⅲ ~ Ⅳ stage) were selected. The patients were randomly divided into two groups: CIK cells treated group (38 patients) and chemotherapy group (36 cases). Patients in CIK cells group received CIK cell infusion therapy , and patients in chemotherapy group received only gemcitabine. The efficacy and safety of all patients were observed. Results The efficacy rate of CIK cells group was 29.0%, with no statistical significance compared to chemotherapy alone group (16.7%). Disease control rate was 63.2%, with statistical significance compared to the chemotherapy group (38.9%). The PFS was 3 months (95%CI:2.5 ~ 3.5), OS 6.8 months (95%CI:6.1 ~ 7.5). 6-month survival rate 41.7%, with statistically significance compared to chemotherapy group. Conclusion CIK cells treated in patients with advanced pancreatic cancer is feasible and safe , and can improve disease control rate , improve immunity and produce clinical benefit in patients.

Aerospace medicine has paid more and more attention to abnormal changes of physiological functions induced by weightlessness and studies on their prevention during space flight. In this paper, the effect of space weightlessness on cognitive functions was introduced. We tried to analyze the correlation between the cognitive function changes and relevant Chinese medical syndromes, thus providing a potential available way to prevent and treat weightlessness induced cognitive deficit during space flight.

The dynamic of endophytic bacteria at different growth stage of tomato and use of these endophytic bacteria to control tomato bacterial wilt were studied. The results showed that endophytic bacteria could be found in the tomato seeds and their quantities reached the highest peak in the adult plants both in resistant and susceptible cultivars. The amount of endophytic bacteria in adult plants of resistant tomato cultivars was 2.43?10~5CFU/g FW in the root and 22.9?10~4 CFU/g FW in the stem, while the amount of endophytic bacteria in adult plants of susceptible tomato cultivars was 9.8?10~4CFU/g FW in the root and 13.4?10~4CFU/g FW in the stem respectively. Seventeen strains of endophytic bacteria from resistant cultivars and only seven strains from susceptible cultivars were found to be antagonistic to Ralstonia solanacearum. In addition, some strains of endophytic bacteria had the abilities of promoting tomato seed germination and controlling tomato bacterial wilt, among which, strain 5R and 3R had better control effect of 91.7% and 81.3% respectively.
