Microorganisms can affect the development of body immune system.Intestinal flora regulate immune function by promoting the intestinal immune system development,inducing T cell differentiation to avoid or reduce the incidence of immune-related diseases.Allergic diseases are related with the body's immune system hypoplasia and imperfect immune regulation mechanism.The immune system can be affected by intestinal flora,and the distribution of flora in the body between children with allergies and healthy children are significantly different,indicating that the occurrence of allergic diseases are associated with intestinal microflora.Studies have reported probiotic are helpful to the prevention and treatment of allergic disease,providing a new way for the prevention and treatment of allergic diseases.

Based on clinical features of refractory diseases and clinical practice experience for many years,the author expounded the therapeutic strategies from establishing individualized system of differentiation treatment,treatment strategies of refractory diseases,and the key for medication,and emphasized individual concerned therapy,separating primary and secondary treatment and grasping the physiological state to treat pathological changes.Thus complicated and changeable diseases can be treated clinically.

AIM: To investigate the effect of Guishen Capsule(Radix Angelicae Sinesis,Radix et Rhizoma Salivae Miltiorrhizae,etc) on mastoplasia and T-lymphocyte subsets of spleen in rats. METHODS: The model of mastoplasia was induced by benzoate estradiol intraperitoneal injection in SD female rats.The model rats were treated with low,middle and high dosages of Guishen Capsule,respectively.All rats were killed after 30 days,the tissue of second pair of mammary glands were observed.At the same time,the spleens were taken out for preparing single cells suspension.The ratio of CD~+_3,CD~+_4,CD~+_8,CD~+_4/CD~+_8 of splenic T-lymphocytes were determined by flow cytometry(FCM). RESULTS: Compared with normal group,the growth of weight was slow in model group,and its breast was swollen,and proliferation was obvious in mammary gland tissue,the ratio of CD~+_3,CD~+_4,CD~+_4/CD~+_8 reduced significantly in model group. Guishen Capsule could inhibit the breast swelling and mammary gland hyperplasia.It also could increase ratio CD~+_3,CD~+_4,CD~+_4/CD~+_8 of splenic T-lymphocytes remarkably. CONCLUSION: Guishen Capsule can inhibit mammary gland hyperplasia.It also has the function of immunologic enhancement and cellular immune regulation.

Objective To study the chemical constituents from the fungal fruiting bodies of Ganoderma sinense.Methods Individual constituents,isolated and repeatedly purified on silica gel and Sephadex LH-20 column chromatography,were identified by physicochemical constants and structurally elucidated by spectral methods.Results Four compounds were isolated and identified as: sinensoic acid(1),cerebroside D(2),poke-weed cerebroside(3),hemisceramide(4).Conclusion Compound 1 is a new compound,others are isolated from the fungus of Ganoderma for the first time.

Objective To investigate the clinical value of negative pressure vacuum cushion combined with thermoplastic body membrane in radiotherapy for Wilms tumor in children.Methods A total of 42 pediatric patients with Wilms tumor who received radiotherapy after surgery were enrolled in the study and were randomly divided into two groups according to the fixation positions:group A and group B.During radiotherapy, the patients in group A were fixed with negative pressure vacuum cushion, and those in group B were fixed by negative pressure vacuum cushion combined with thermoplastic body membrane.The setup errors, short-term effects, adverse reactions, and prognosis were compared between the two groups.ResultsGroup B showed significantly lower translational errors and rotational errors, as well as significantly higher rates of ≤3 mm and ≤5 mm errors, compared with the group A (P=0.04,0.04,0.04,0.03,0.00,0.04,0.04,0.00,0.04).Group B also showed significantly higher complete remission rates and response rates than group A (P=0.02,0.04).There were no significant differences in the adverse reaction rates (P=0.75) and the overall survival (OS) rates at 2 and 3 years (P=0.68,0.74) between the two groups.Group A had the MPTV values in left-right (LR) direction (x-axis), superior-inferior (SI) direction (y-axis), and anterior-posterior (AP) direction (z-axis) being 5.74 mm, 5.93 mm, and 5.94 mm, respectively, and group B had the MPTV values at LR, SI, and AP directions being 4.21 mm, 5.71 mm, and 4.61 mm, respectively.Conclusions In the radiotherapy positioning for Wilms tumor in children, fixation limbs with negative pressure vacuum cushion combined with thermoplastic body membrane effectively reduces the setup errors and improves the effect of radiotherapy, so it holds promise for clinical application.

Objective To evaluate retrospectively ECG -gating for the coronary angiography with MSCT. Methods 15 patients were studied with a multislice spiral CT on retrospective ECG -gating,0.5s rotation, and cardial segment reconstruction algorithm. Nine phases were chosen to reconstruct images of coronary arteries. Results In the 230 coronary artery segments,213 (91%)were best visualized at 70%. And 15 (6.4%), 9 (3.8%), and 3 (1.3%) were optimal at 80%, 40% , and 5% of the cycle respectively. Conclusion The coronary arteries usually are best visualized at 70% image reconstruction window of the cardial cycle.

Cellular functions like proliferation,differentiation,migration,morphogenesis and apoptosis are modulated by the extracellular matrix.Integrins are the prototypic heterodimeric transmembrane matrix receptors with competing affinities for individual extracellular matrix ligands.The intracellular integrin domain clusters cytoplasmic proteins into focal adhesion plaques for bidirectional(outside-in and inside-out) signaling.Integrin-linked kinase(ILK) is an intracellular serine/threonine protein kinase that interacts with the cytoplasmic domains of ?-integrins.ILK organizes the connections of the extracellular matrix via integrins to the cytoskeleton and is involved in adhesion plaque signaling,and it plays a crucial role in the pathogenesis of chronic renal fibrosis.High glucose induces the upregulation of the synthesis and activity of ILK in cultivated mouse podocytes and mesangial cells.The ILK protein level is significantly increased in diabetic glomeruli.ILK activity is likely to provide the basis for an effective therapeutic method for diabetic nephropathy.This review gives an introduction of ILK structure and function,followed by a summary of our current understanding of ILK in diabetic nephropathy with a special focus on glomerular cell-matrix interaction.

Abnormal endothelial growth factor receptor transportion was involved in the development of tumor so more and more researches focus it as a target of anti-tumor therapy. Based on the known mechanism in EGFR mis-localization this review summarized the latest research progress in the abnormality in signal of EGFR transportation and its role in tumori?genesis, anti-tumor drug and therapy that target to EGFR. It is aim to provide reference for the development of anti-tumor treatments which target EGFR and for the mechanism in resistance of anti-tumor.
