Henoch-Sch?nlein purpura(HSP)is an IgA-associated leukocytoclastic small-vessel vasculitis, commonly occurred in children.Recent studies have shown that its pathogenesis is closely related to the disturbance of humoral immune response mediated by B cells.CD4 + T cells have the function of help B cells.Each subgroup of CD4 + T cells has unique functions of promoting or regulating immune inflammatory response.There are abnormal changes in the proportion of CD4 + T cells subsets in HSP patients, including the imbalance of Th1/Th2, increasing numbers of Th17 and Tfh cells, together with decreasing Treg cell numbers.The changes are closely related to the occurrence, development and the clinical phenotype of HSP.It is suggested that the detection of CD4 + T cells plays critical roles in guiding the evaluation of HSP, and is expected to provide a new idea for the clinical diagnosis and individualized treatment of HSP.

Edema, as one of common clinical diseases, could be treated by taking medicines and adopting external therapies with traditional Chinese medicines (TCM). In recent years, there have been many clinical and basic studies concerning external therapies with TCM on edema Data showed that the external therapies are mostly composed of such purgating drugs as Rhei Radix et Rhizoma, Natrii Sulfas and Pharbitidis Semen, heat-clearing drug such as Phellodendri Chinensis Cortex and resuscitation-inducing drug such as Borneolum Syntheticum. The study showed that ingredients of external therapies did not pass through hilum and hepatic system, and thus avoided the first pass effect of livers. They enabled effective components of drugs to be rapidly absorbed through pores and skins, strengthened the effect against edema, shortened the treatment course, decreased side effects, and were convenient and inexpensive. External therapies with TCM could play unique advantages in inhibiting edema in the future clinical studies.

Objective:To analyze two different kinds of mouse model with immune thrombocytopenic purpura for the immune mechanisms.Methods:Immune thrombocytopenic purpura was induced by either injection of polyclonal antibody or immunized inoculation with rat platelets.Results:The two kinds of model all induced decrease of platelets,while immunization with platelets of rat induced alloantibodies in the mice.Conclusion:Immunization with platelets of rat can mimic the production process of autoantibodies in human and lead to immune thrombocytopenic purpura in mice.

Objective: To study the periapical microleakage of the root canals filled with four kinds of sealers using two obturation techniques. Methods: Sixty-four extracted first maxillary premolars were randomly divided into four groups. All the root canals were prepared with Protaper rotary instruments and filled with two obturation techniques: warm vertical condensation and cold lateral condensation. Four kinds of sealers included: Cortisomol, nano-zinc oxide, Apexit and calcium hydroxide which were indivi-dually used for four groups. After the teeth were dyed for 7days with Indian ink, dyeing lines were measured with digital camera under steromicroscope to reflect the microleakage. Results: In cold lateral condensation groups, dyeing lines of calcium hydroxide group had an average length of (1.75?0.22) mm, which was significantly longer than that of Cortisomol group (1.40?0.15 mm) and nano-zinc oxide group [(1.56?0.25) mm, P0.05], which were significantly shorter than that of cold lateral condensation groups (P

ObjectiveTo observe the effect of early rehabilitation on poststroke anxiety and depression.Methods137 stroke patients with hemiplegia were divided into the rehabilitation group (70 cases) and control group (67 cases). All patients in both two groups were given routine clinical treatment, but the patients in the rehabilitation group were given regular early rehabilitation. All patients were evaluated with Bathel Index (BI), Fugl-Meyer Motor Scale (FMMS), Hamilton Depression Scale (HAMD) and Hamilton Anxiety Scale (HAMA) before and 3 months after treatment.ResultsAfter 3 months treatment, the scores of HAMD, HAMA, BI and FMMS of patients in the rehabilitation group increased significantly compared with those before treatment ( P<0.05～0.01), and those in the control group ( P<0.05). The scores of BI and FMMS of patients in the control group after treatment also increased significantly compared with those before treatment ( P<0.05). The incidences of depression and anxiety of the rehabilitation group were 22.86% and 5.71%, those of the control group were 40.30% and 16.42%, there was a significant difference between two groups( P<0.05).ConclusionThe early rehabilitation can obviously decrease anxiety and depression of stroke patients with hemiplegia.

Objective To analyze the clinical and radiographic features of short stature combined with skeletal deformity in children,and to diagnose exactly and cure promptly in children.Methods One hundred and twenty children were collected,included 69 males and 51 females.All of the children were collected detail medical history including history of birth,feeding,growth and development and family history and taken both physical and X ray examination that bone age could be evaluate by Gruelich-Pyle method.The children were taken a laboratory examination including calcium,phosphours,alkaline phosphatase,chromosome karyotype,and so on.Results Among 120 children,there were 36 cases(30.0%) of achondroplasia,20 cases(17.0%)of Turner syndrome,10 cases(8.0%)of multiple epiphyseal dysplasia,1 case(0.8%)of spondyloepiphseal dysplasia congenital,7 cases(5.8%) of spondyloepiphyseal dysplasia tarda,2 cases(1.6%) of osteogenesis imperfecta,1 case(0.8%) of cleidocranial dysplasia,5 cases(4.2%)of mucopolysaccharide Ⅳ,5 cases(4.2%) of pseudoachondroplasia,9 cases(7.5%)of hypophosphatemic ricket,24 cases(20%)of short limb dwarf.Among 120 cases,27 were regularity dwarfism(22.5%),93 cases were irregularity dwarfism(77.5%);Among 93 cases of irregularity dwarfism,80 cases were short limb dwarfism including 36 cases of short upper limb(short upper arm 35 cases,shortforearm 1 case),20 cases of short lower limb,24 cases of proportional short stature,13 cases of short trunk.X ray bone age lag 46 cases,ahead of schedule 15 cases(12.5%),normal 59 cases.Conclusions The main causes of short stature combined with skeletal deformity are genetic bone disease.To analyze the feature of clinical and radiographic is a valuble instrument for the children diagnosis of short stature combined with skeletal deformity.Part of them skeletal age were lagged.

Objective: To observe the effect of aqueous extract from roots of Arctium lappa (AERAL) on vascular remolding in hypertensive rats. Methods: The hypertensive rat model was induced by N-nitro-L-arginine from 50 female Wistar rats, and randomly divided into model control group, positive control group (15 mg/kg), low-, mid-, and high-dose AERAL (0.5, 1.0, and 2.0 g/kg), groups. After six weeks of continuous gavage administration, rat tail artery systolic pressure, angiotensin II (Ang-II), endothelin-1 (ET-1), tumor necrosis factor-α (TNF-α), left ventricular mass index (LVWI), and thickness of thoracic aortic tunica media (TTATM) were detected. Results: Compared with the normal control group, Ang-II, ET-1, TNF-α, LVWI, and TTATM were increased and rat tail artery systolic pressure was elevated in the model control group, with significant differences between the two groups (P < 0.05); Compared with the model control group, rat tail artery systolic pressure in each treatment groups declined, serum Ang-II, ET-1, TNF-α, LVWI, and TTATM were all lowered, showing significant differences among them (P < 0.05). Conclusion: AERAL can significantly improve vascular remolding in rats with hypertension.
