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.

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 multiple painless needle insertion skills in clinic combined with own experience, the authors propose the opinion that different painless needle insertion methods need to be used according to the positions where acupoints are. The appropriate needle insertion mean must be selected in accord with the anatomical characteristic of acupoint position, namely, tapping insertion is applied in scalp part, skin-pinching up needle insertion is used in forehead and superficial nerve trunk, fingernail-pressure needle insertion in ocular region and positions where large blood vessels distribute, flying acupuncture insertion in face and finger tip, vibrating needle in occipitonuchal region, quivering insertion in abdomen, quick pricking by single hand in the four limbs and back, and chop acupuncture in palm and pelma. The insertion methods are systematically discussed in terms of preparation, acupoint position, manipulation and attention, etc, so that to provide the reference for painless needle insertion.

Caloric restriction has been practiced over 500 years as a method for increasing both the length and quality of life.Experimental work confirming the success of this approac h in animals has accumulated in the last 100 years.Since 2000,emerging evidence in humans has shown that caloric restriction can delay the onset of age related diseases including reduced risk of obesity,diabetes,cardiovascular disease,cancer,and neurodegenerative disorders.The mechanisms and clinical applications have been extensively studied.

Objective To investigate the changes of peripheral benzodiazepine receptors (PBRs)in rat spinal cord synaptosomes during ageing and to explore the correlation between PBRs in spinal cord synaptosomes and PBRs on platelet membranes.Methods A total of 24 Sprague-Dawley rats were divided into 3-month group and 24-month group (n=6 males and 6 females for each).All animals were sacrificed by decapitation and the spinal cords were immediately removed.Synaptosomal fractions from spinal cords were isolated by gradient centrifugation.The platelet membranes were prepared from venous blood by the method of hypotonic haemolysis.The specific binding of the radioactive PBRs antagonist [3H]PK11195 to membranes was determined.Results No significant differences in [3H] PK11195 binding activity in spinal cords and platelet membranes were observed between male and female rats in the same group (all P＞0.05).[3H] PK11195 binding activity in spinal cords and platelet membranes were higher in 3-month group than in 24 month group [(213.94±10.65) fmol/mg pro.vs.(50.65± 2.74) fmol/mg pro.,(104.97± 2.24) fmol/mg pro.vs.(56.20±5.36) fmol/mg pro.,respectively,t=51.418,29.041,both P＜ 0.001].There was a positive correlation between [3H]PK11195 binding activity in platelet membranes and in spinal cord synaptosomes (r=0.985,P＜0.001).Conclusions The level of PBRs is gradually decreased in rat spinal cord synaptosomes with ageing.[3H] PK11195 binding activity of platelet membranes can reflect the changes of PBRs in spinal cords.

With the neonatal intensive care techniques developing,the survival rate of preterm infants has increased markedly.However,these survival preterm infants are extremely vulnerable to develop various diseases,of which brain injury is the most important cause of the disability in preterm infants.At present,encephalopathy of prematurity,the incidence of which is rarely reported in domestic and national reports,mainly refers to white matter injury (WMI).This article reviews the different domestic and national reports about the incidence of encephalopathy of prematurity.

[Summary] Epidemiologic evidence favors strong correlations between low thyrotropin(TSH) and high bone turnover, low bone mineral density ( BMD), and high fracture risk in hyperthyroid patients. Even subclinical hyperthyroidism, in which TSH is low and thyroid hormones are normal, is associated with osteopenia and osteoporosis. These evidences indicate that action of TSH on bone metabolism is independent of thyroid hormones and thus support the theory of the pituitary-bone axis. TSH plays its osteoprotective effect by binding TSH receptor on osteoclasts and inhibiting TNF-α expression. Physicians should screen the BMD in patients with overt and subclinical hyperthyroidism, especially the elderly, and make early diagnosis and better management for the underlying osteopenia and osteoporosis.

Adhesion molecules (AM) are a class of molecules that can mediate cell-to-cell and cell-to-matrix interaction. They participate in the cellular recognition, signal transduction, cell proliferation and differentiation, cell stretching and movement through ligand-to-receptor interaction. AM are the molecular basis of immune response, inflammation, blood coagulation, tumor metastasis, wound healing and a series of physiological and pathological processes. Kawasaki disease (KD) is an acute systemic small vasculitis syndrome, mainly affecting coronary artery. KD is the main cause for acquired heart disease in children. To study the relationship between AM and pathogenesis of KD is important in the understanding of KD pathogenesis, prevention and treatment of coronary artery lesions complicated with KD. This review focused on the relationship between AM and pathogenesis of KD.
