Objective To know about care experience and medical care demands of caregivers of retinopathy of prematurity children in order to provide reference for clinic. Methods A total of 11 caregivers were interviewed by qualitative research methodology. Data and subjects were refined by Colaizzi methodology. Results Totally 3 subjects about care experience were extracted, which were high psychological pressure, heavy caregiver burden, desire for medical and nursing support. Conclusions Medical care personnel should improve treatment system of retinopathy of prematurity and provide information and psychological support in order to improve quality of life of children.

Objective:To observe the effects of Qingluotongbi granule(QLT) on the changes of cytokines in adjuvant induced arthritis(AIA) model of rats.Methods:The AIA model of rats were induced by complete Freunds adjuvant. Various doses of QLT were given by gavage once daily for 21 days.Results:QLT〔7.2,14.4 g/(kg?d).ig〕markedly decreased the levels of IL-1 and TNF-? in AIA rats.Conclusion:QLT has modulating effects on the alternations of cytokines of AIA model.

Objective To compare and analyze the biochemical detection results of separated se- ra with the separation gel coagulation promoting tubes and the drying tubes. Methods Venous blood samples was collected from identical blood donors and randomly poured into the separation gel vacuum collective tubes (test group) and traditional drying collective tubes (control group). After serum sepa- ration, timely biochemical detection was performed. The detection results were compared and ana- lyzed. The samples of test group were detected once again after storage for 24 h at 4 ℃. The results were compared with those of timely biochemical detection with separation gel separated sera. Results The results from the test group and those from the control group had no significant difference. The most results from the sera storaging for 24 h at 4 ℃ and those from the fresh serum of the test group had good correspondence. Only a few of biochemical indicators had significant difference. Conclusion The biochemical detection with sera obtained by separation gel tubes and those collected by drying tubes has good correspondence. The separation gel tubes provide the clinical laboratory optimal blood samples and more accurate results.

The establishment of induced pluripotent stem (iPS) cells is considered as one of the most important progresses in science and technology nowadays. In recent years, the iPS cells have been used in the construction of cellular model for hereditary heart disease, and the successful treatment in animal model of myocardial infarction, which brings a bright future for exploring the pathogenesis and therapy of hereditary heart disease.

AIM: To observe the effect of Qingluo Tongbi Granule(QLTBG)——containing serum on the proliferation of osteoblasts(OB) and osteoclasts(OC),the activity of AKP of OB. METHODS: (1) OB were separated from the skull of SD rats aged 1 d and OC from the thighbone and shinbone of SD rats aged 5 d.(2) The proliferation of OB and OC was detected by MTT method,and the activity of AKP of OB was examined by diazol method. RESULTS: The proliferation capability of OB was strengthened markedly by the rat sera containing 7.2,14.4 g/kg QLTBG,which could reinforce the activity of AKP obviously as well,while the proliferation of OB was inhibited remarkably by the rat sera containing 3.6,7.2,14.4 g/kg QLT. CONCLUSION: The sera containing QLTBG could enhance the proliferation of OB and the activity of AKP,restrain the proliferation of OC simultaneously.

Objective:To investigate the effects of Qingluotongbi granule(QLT) on RANKL(receptor activator of nuclear factor-?B ligand) expression in peripheral blood T lymphocytes of RA patients.Methods:RANKL expression of peripheral blood T lymphocyts was examined using flow cytometry.Six cases of RA patients were enrolled with six healthy volunteers as the control.Meanwhile examination for the level of RANKL expression in T cells after incubation in presense of QLT-contained serum was observed.Results:RANKL expression of peripheral blood T lymphocytes was much higher in active state RA patients than in healthy people(P

Objective:To study the mechanism of Qingluo Tongbi Compound (QLT) treating rheumatoid arthritis(RA)by observing miRNA Network of QLT on collagen-induced arthritis ( CIA) mice.Methods:The model of RA was induced by collagenⅡin DBA/1 mice and randomly divided into control group , CIA group, QLT group.Differently expressed miRNAs were detected by miRCURYTM LNA Array.Real-time PCR was applied to verify the reliability of miRNA array.Results:The bioinformatics software and database were applied to predict and analyze target genes.MiRNA array results showed that 221 miRNAs changed in CIA group compared with the control group ,and 169 miRNAs changed in QLT group compared with CIA group.And the results of real-time PCR were consistent with the array.Compared with the control group ,miR-143 was significantly reduced in CIA group ,intervention of QLT obviously upregulated the expression of miR-143.The target genes of miR-143 were significantly stored in VEGF , T cell receptor, MAPK,signaling pathway.Conclusion: Multiple abnormal expression of miRNAs involved in the pathological process of CIA.QLT affected the expression of various miRNAs ,which might be related to immunity ,inflammation,pain pathological process of RA and miR-143 could be a potential target in the treatment.

In this study, we applied generalized autoregressive conditional heteroskedasticity (GARCH) model to conditional fluctuation characteristics of heart rate variation (HRV) series (congestive heart failure, Normal), with all the data from PhysioNet ECG database. Research results proved the existence of condition fluctuation characteristic in the series of changing rate of HRV. In the GARCH model family, threshold GARCH (1,1)(TGARCH (1,1)) model performs best in fitting changing rate of HRV. Although the structure of ARCH (1) model is simple, its error is the closest to that of TGARCH (1, 1) model. The results also showed that the difference was obvious between disease group and normal group. All these results provide a new method to the research and clinical application of HRV.

Objective To observe the effect of non-ablative treatment combined intense pulse light (IPL) and Q switched Nd :YAG laser on hyperpigmented skin diseases. Methods Total 250 cases of Fitzpatrick skin types Ⅲ and Ⅳ with hyperpigmented skin disorders received 4 treatments with combined 560nm IPI. and 532 nm Q switched Nd :YAG laser. The interval between two treat-ments was I month. After 3 months the effect of IPL was observed. If it was not good, we used the Q switched Nd :YAG laser. Efficacy and adverse effects were evaluated 3-6 months after the final treat-ment. Results 3-6 months after the last treatment, 50%-70% of patients had their telangiectasia, enlarged pores, hyperpigmentation and wrinking of facial photoaging improved. The degree of im-provement was more than 60 %. Common side effects were minor blistering and erythema. Conclusion Combined IPI. and Q switched Nd :YAG laser treatment is an idea non-ablative therapy for telangi-ectasia, enlarged pores, hyperpigmentation and wrinking of facial photoaging in Fitzpatrick skin types Ⅲ and Ⅳ in Asian.
