The aim of this study was to explored the mechanism of inhibitory effect of chloroquine on IL-6 release induced synergistically by bacterial DNA and endotoxin. Before experiment mice were sensitized for 1 hour with D-GalN by I.P. injection. Mortality within seven days was observed after mice were challenged with CpG ODN or LPS with or without chloroquine treatment. ANA-1 cell line cells were cultivated in vitro. We investigated the influence of chloroquine on IL-6 release induced by both EC DNA and LPS. Expressions of TLR4 and TLR9 and activation of NF-?B p65 were investigated in cultured THP-1 cells pretreated with chloroquine and stimulated by EC DNA and LPS. The results showed that all mice died within 4 hours after challenged with CpG ODN and LPS. Only 4 or 5 mice pretreated with chloroquine (30mg/kg) died after challenged with CpG ODN and LPS (P

Objective To explore the effects of case method teaching in the medical postgraduate student of dermatology English teaching. Methods The experiment group was taught by case method teaching, and the control group was taught by traditional teaching model. The quantitative research and questionnaire investigation were used to evaluate the teaching methods. Results (1) There were significant differences in professional English test scores of Dermatology between the two groups;(2) The questionnaire investigation revealed that the case method teaching have achieved a higher evaluation from students in stimulating their enthusiasm of learning English,cultivating their ability of using language and improving capability of resolving clinical problem. Conclusion Case method teaching could help students cultivate the abilities to interpersonal communication and cooperation, raise the sense of innovation and innovation capacity,strengthen the relation between skills and theoretical knowledge, and improve the ability of self-management, learn cooperation and information literacy. But we should improve the case-based teaching and evaluation methods,in order to improve the teaching method of case teaching quality.

Objective To explore the security of spinal anesthesia by observing the pefioperation serum troponin T in the elderly patients with coronary heart disease who underwent spinal anesthesia.Methods 40 case8 were divided into two groups according to the elderly patients with or without the history of coronary heart disease.Group Ⅰ 0f 20 cases were the patients with the history of coronary heart disease.Group Ⅱ of 20 cases were the patients without the history of coronary heart disease.Both groups were undertaken single spinal anesthesia combined with epidural anesthesia.The blood samples were collected at the time of perioperation,the end of the operation and 24 hours after surgery.The serum troponin T Was tested by Roche fully automated ehemiluminescent analyzer E170.The symptoms and signs of the coronary heart disease in the patient were observed.And the age,operation time,anesthesia lever,the amount of bleeding and transfusion were recorded,and at the same time,electrocardiogram,heart rate,pulse,cerebral oxygen saturation were monitored.Results There was no significant difference between two groups in age,operation time,anesthesia lever,the amount of bleeding and transfusion,heart rate,pulse,cerebral oxygen saturation.There was no significant difference between two groups in seram troponin T.No symptoms and signs of the coronary heart disease were observed in two groups.There Was no significant difference between two groups in constituent ratio of positive rate of serum troponin T.There was one case in each group that serum lroponin T was more than reference value (0.010μg/L)during the perioperation while the patient was no discomfort.Conclusion Spinal anesthesia has no impact on the change of perioperative 8ertlm troponin T in the elderly patients with coronary heart disease.

Objective To investigate the roles of CpG motifs in the release of cytokines induced by bacterial DNA. Methods Mice were sensitized with injection of D GalN (600 mg/kg) into the abdominal cavity 1 h before experiment. Mortality was observed after purified Escherichia coli DNA(EC DNA), calf thymus DNA(CT DNA), phosphorothioate backbone CpG oligodeoxy nucleotides (CpG ODN) and CG sequence inverted oligodeoxy nucleotides (non CpG ODN) were injected venously into mice. The injection dosage of DNA given was 30 mg/kg but ODN was 10 nmol/mouse. THP 1 cell lines were cultured in vitro . After the above reagents were added into the culture, TNF ?, IL 6, IL 1? levels were detected to observe the different abilities of these reagents to induce the release of cytokines. Results EC DNA and CpG ODN could induce the death of mice and the large amount of release of cytokines, but CT DNA and Non CpG ODN could not. Conclusion CpG ODN has the ability to induce macrophage to release cytokines largely. CpG motifs, which may play an important role in the release of cytokines induced by bacterial DNA, may probably be the structural basis of bacterial DNA.

Objective: To investigate the childrens congenital and acquired nutritional status and the physical development among the different nationalities in Guizhou province; to find out the factors that greatly influence the childrens physical development. Methods: Investigations were carried out on the diet, height and the weight of the mothers during the early and late stage of their pregnancy and after the delivery of the babies. Results: The living conditions in the groups of Miao and Buyi were very poor. For the pregnant women among Han, Miao and Buyi groups, during their middle and late stage of the pregnancy, the intakes of protein, calcium and VB 2 did not reach 80% RDA. For the 2-4 years old children, the intake of protein was below 80% RDA. For those in Miao and Buyi groups, the chief source of protein was from cereals. There was a great insufficient intake of calcium and VB 2 in different age groups of the children mentioned above. With the increase of age, the infants of Buyi and Miao groups were gradually diverting from the standard criterion from 3rd or 4th month. The greatest difference was in Miao group, i.e. at the age of 6, the difference in height was 9.8 cm(male), 8.3 cm(female); the difference in weight was 1.64 kg(male), 1.92 kg(female). Conclusion: The physical development of the infants in Buyi and Miao groups is inferior to those in Han group. Besides the environmental influence, the quality and quantity of the protein in diet play an important role in physical development.

In this paper,we analyzed one case of primary multifocal extranodal non-Hodgkin's lymphoma and reviewed the related literatures.We investigated the clinical data of this case with primary multifocal extranodal lymphoma and retrospected the related references.The key words,primary extranodal lymphoma and multifocal,were used to search Pubmed and Wanfang Database,and finally only three cases were found.The 68-yea-old woman was confirmatively diagnosed as primary multifocal extranodal B cell non-Hodgkin's lymphoma.The positron emission tomography/computed tomography (PET/CT) scan showed multiple hypermetabolic lesions in the left humerus,both kidneys and ileum.The confirmative diagnosis was based on clinical manifestations and serological tests,imaging features of CT and PET/CT,and especially on the histopathological and immunohistochemical studies.After one cycle chemotherapy (rituximab,Vincristine and prednisone) and another cycle (rituximab,Vincristine,cyclophosphamide and prednisone),a repeat PET/CT scan showed a complete metabolic resolution of the lesions in the kidneys and ileum,and a partial metabolic resolution of the left humerus.After four cycles of chemotherapy,there were new extensive involvements of the right supraclavicular and intrapulmonary lymph nodes,bilateral pleural and pericardium,and the patient gave up chemotherapy.This case demonstrated the imaging findings of an uncommon primary multifocal extranodal lymphoma in left humerus,both kidneys and ileum,and highlighted the usefulness of CT and PET/CT scan in identifying the extent of disease involvement,in guiding a biopsy,and in assessing the treatment response of lymphoma.It is essential to differentiate between primary multifocal extranodal lymphoma and lymphoma extensive metastases.
