Based on analyzing and evaluating ability of social skill of an child with learning disability, this research designed a 3-month project to teach social skill for the child. Through educational propaganda before the teaching, peer-participation, activities of cell-teaching and combining with various strategies to facilitate apperception of social skills. The result indicated that teaching social skill in regular class for learning disability is effective and useful.

OBJECTIVE: To observe the effect of formaldehyde inhalation on the allergic rhinitis mice model. METHOD: Forty-eight male BALB/C mice in six experimental group were exposure to (A) saline control; (B) Der p1; (C) formaldehyde (3.0 mg/m3); (D) Derp1 + formaldehyde (1.5 mg/m3); (E) Der p1 + formaldehyde (3.0 mg/M3); (F) Der p1+ formaldehyde (6.0 mg/m3). The concentrations of IL-4, IL-10 and IFN-γ in the peripheral serum were measured by enzyme-linked immunosorbent assay(ELISA). Nasal mucosal inflammation was evaluated by HE staining. Result: Formaldehyde exposure could increase the number of allergic rhinitis mice with sneezing and rubbing nose. The levels of IL-4 and IL-10 in group B, D, E and F were higher than that ingroup A (P < 0.05). Compared with the group C, the group D, E and F could effectively increase serum IL-4 and IL-10. The concentration of IL-4 in group E and F was higher than that of group B, while the group C was lower (P < 0.05). The concentration of IL-10 in group D, E and F was higher than that in group B (P < 0.05). The expression of IFN-γ in group B, D, E and F was lower than that in group A. While, the IFN-γ expression in group B was lower than that of group C and higher than that in group F (P < 0.05). Moreover, the concentration of IFN-γ in group D, E and F was lower compared with group C (P < 0.05). The nasal mucosa HE staining showed that the density of EOS increased simultaneously in formaldehyde exposure allergic rhinitis groups. CONCLUSION The study showed that formaldehyde exposure can promote Th2 cytokines and eosinophil infiltration and then aggravate the allergic rhinitis symptoms.

Ischemic stroke is one of the diseases with the highest morbidity and disability.Hypertension is recognized as the most important independent risk factor for ischemic stroke.Vascular remodeling during the development of hypertension is the pathological basis of causing ischemic stroke.Studies have shown that vascular smooth muscle cell proliferation and apoptosis will lead to vascular remodeling.In addition,cerebral ischemia-reperfusion can result in neuronal damage and apoptosis.Recent research has shown that vascular remodeling and neuronal apoptosis are associated with chloride channels.At least 3 chloride channels including volume regulated chloride channel,calcium activated chloride channel and cystic fibrosis transmembrane conductance regulator are involved in these processes.This article reviews the roles of the 3 chloride channels in vascular remodeling,neuronal apoptosis,and ischemic stroke.

The Doctor Practical Technique Test is one of the two important parts in the Doctor Qualification Tests.The article expounds its importance and complication as well as how to grasp each point of the test.It also makes a statistic analysis of its test results in Chongqing,the feedback information of which will be an enlightenment and help to the reforms in medical education and the standarlized training of clinical residents.

Aim To explore the protective role of schisandrin B (SchB)against HK-2 damage induced by Cisplatin and the probable mechanism.Methods Cultivated HK-2 was interacted by Cisplatin and SchB with different concentrations.Invert microscope showed cellular form change and Flow Cyto Meter told apopto-sis.Combined with test result on the change of L-DH, MDA and LPO,probable protective effect of SchB on HK-2 was studied and analyzed.Result Cisplatin in-hibited cells′growth and induced apoptosis.20 μmol · L-1 SchB significantly reduced apoptosis of Cispla-tin-induced HK-2,and offered the best protection. SchB could reduce MDA,LPO,LDH significantly in-creased by cisplatin.Conclusion SchB can be an ef-fective inhibition agent of Cisplatin-induced renal tubu-lar epithelial cell apoptosis (HK-2 ).The mechanism can be the inhibition of Cisplatin-induced oxidative stress by antioxidant effect.

As a series of multifunctional cells,recent studies indicate that most of the CD4 + T lymphocyte subsets involve in the tumor angiogenesis and invasion,the apoptosis of tumor cells,and the expressions of acute phase proteins and cancer-promoting genes by activating or inhibiting the innate immune cells,the adaptive immune cells and non-immune cells,thus function as tumor promoters or inhibitors in hepatocellular carcinoma (HCC).

Objective To study the various clinical manifestations of niemann pick disease, and to improve the ability of diagnosis and differential diagnosis in order to reduce misdiagnosis or missed diagnosis.Methods The onset and diagnostic procedure of a seven-month-old infant with niemann pick disease were reported and relative literature were reviewed and studied.Results The infant demonstrated severe hepatosplenomegaly, abnormity of liver function, anemia and development backwardness.Bone marrow examination indicated storage cells suggestive of niemann pick cells.Conclusion Niemann pick disease is a group of rare diseases with various clinical manifestations. Clinical suspected cases need further bone marrow examination, pathologcal biopsy and gene tests.

High mobility group protein box 1 (HMGB1) is a typical nonhistone chromosomal protein. It has many celular functions in nucleus. Studies in recent years have showed that HMGB1 can be released to the outside of cels to exert a wide range of cytological effects. Ischemic stroke is one of the diseases with the highest morbidity and disability. More and more evidence has shown that HMGB1 plays a variety of important roles in the occurrence and development process of ischemic stroke. This article reviews the roles of HMGB1 in ischemic stroke.

Moyamoya disease is a chronic progressive cerebrovascular disease. Its main manifestation is bilateral internal carotid artery progressive stenosis w ith abnormal vascular netw ork formation of the compensatory hyperplasia in brain base. The pathological mechanism of moyamoya disease is not clear. Grow ing evidence has suggested that immune inflammation may play an important role in its occurrence and development process. Abnormal expression of various inflammatory cytokines and immune proteins can be observed in patients w ith moyamoya disease. This article review s the possible mechanism of immune inflammation in moyamoya disease in recent years.

Objective To investigate the laboratory ifndings, clinical manifestations and treatment in hemolytic disease caused by red cell immune antibodies in neonates. Methods The laboratory and clinical data from 4 cases of hemolytic disease of neonates caused by red cell immune antibodies were retrospectively analyzed. Results IgG antibody were detected in all mothers of 4 cases during pregnancy and they were anti-E, anti-D, anti-Jkb and the autoantibody with the titer being 16, 2048, 1 and 16 respectively. The four neonates were all full-term. The jaundice appeared 6 h to 3 d after birth with varying degrees of skin stained yellow, with or without anemia. Serology and elution test found the existence of antibody same as the one on their maternal red cells and the titer was 4, 512, 0, and 2, respectively. All neonates were treated by phototherapy. Two servere cases were also treated by whole blood exchange and red blood cells transfusion. The prognosis were good in all neonates. Conclusions Prenatal immune hematological tests facilitated early detection of irregular erythrocyte antibodies and thus assessment of the risk of hemolytic dis-ease of the fetus and neonates.
