Objective To explore the clinical and laboratory characteristics of langerhans cell histiocytosis (LCH) in children, so as to improve diagnosis level and decrease misdiagnosis rate.Methods Twenty-five cases of LCH from Jan.1996 to Feb.2006 were analyzed by retrospective study. The clinical data were collected and abstracted for information regarding clinical symptom, physical sign, laboratory examination, imaging,pathology,diagnosis and treatment.Results Some laboratory findings in hemogram, bone marrow examination and chest X-ray were non-specific.The X-ray characteristic of skeleton was osteolysis. Computerized tomography and magnetic resonance imaging were important in defining the extent of lesion in fundus cranii and sella.Seven cases were examined for anti-Epstein-Barr virus(EBV) IgM, 3 cases were positive;5 and 3 cases out of 10 cases showed humoral and cellular immunity abnormality,respectively. The misdiagnosis rate was 52%,1 case had been misdiagnosed for 7 years. Chemotherapy was effective in the future.Conclusions The clinical manifestations of LCH varies widely, leading to high rate of misdiagnosis.The etiology of LCH is unclear,and some of our patients show the evidence of EBV infection or immunity abnormality. Definitive diagnosis of LCH is based on pathology. Ultrastructure and immunophenotype should be done to improve diagnosis level.

[Summary] It has been believed that both environmental and genetic effects play roles in the pathogenesis of type 2 diabetes. Genetic factors may influence the effect of environmental factors on risk of developing type 2 diabetes. This review focused on the latest evidence of the interaction effect of genes and the environmental factors on type 2 diabetes.

Objective To Analyze the examination meaning of b-type brain natriuretic peptide precursor (NT-proBNP),homocysteine and coagulation-fibrinolysis indexes for patients with acute cerebral infarction.Methods Selected 40 patients with acute cerebral infarction (experimental group) to hospital from March 2014 to May 2015 and 40 healthy check-up cases (control group).Then,compared the indicators in blood between the two groups of patients,namely homocysteine (Hcy),NT-proBNP,activated clotting time live enzymes enzyme (APTT),original activator inhibitory factor (PAI-1) and tissuetype fibrinolytic enzyme original activator (tPA).Meanwhile,also compared these indicators for the experimental group before and after treatment.Results Before treatment,the levels of Hcy,t-PA,NT-proBNP,PAI-1 and ATPP for experiment group were 17.7±3.6 μmol/L,29.4±7.9 μmol/L,3 212.8±2 511.4 ng/L,130.1±17.8 μmol/L and 37.8±4.5 s,respectively.The levels of Hey,t-PA,NT-proBNP,PAI-1 and ATPP for control group were 7.2± 2.1 μmol/L,15.1 ± 3.7 μmol/ L,198.7 ± 1 14.8 ng/L,67.8 ± 7.9 μmol/L and 37.8 ± 4.5 s,respectively.After treatment,the levels of Hcy,t-PA,NT-proBNP,PAI-1 and ATPP for experiment group were 12.2±1.5 μmol/L,18.2±2.3 μmol/L,348.7±194.8 ng/L,78.6±9.8 μmol/L and 32.2±4.5 s,respectively.Before treatment,the indicator of APTT for experiment patients was significantly shorter than it after treatment and that of the control group.The other four indicators were significantly higher than them after treatment and those of the control group.The differences were statistically significant (P <0.05).Conclusion Hcy,NT-proBNP,APTT,PAI-1,and t-PA had closely relation with the occurrence of acute cerebral infarction development,and they can be helpful to evaluate disease progression and predict prognosis for patients with acute cerebral infarction.

OBJECTIVETo explore the effect of Shenxiong Huayu Capsule (SHC) on the cerebral ischemia-reperfusion (IR) injury and the expression of growth associated protein 43 (GAP43) after total cerebral IR in the hippocampal CA1 region of rats.
METHODSTotally 100 male adult SD rats were randomly divided into five groups, i.e., the control group, the model group, the group A (by taking SHC once daily), the group B (by taking SHC twice daily), and the group C (by taking SHC thrice daily), 20 in each group. The total IR model was prepared by improved Pulsinelli's 4-vessel occlusion method. Morphological changes of the hippocampal CA1 region were observed by HE staining at day 1, 3, 7, and 14. The expression of GAP43 in the hippocampal CA1 region was detected using immunohistochemical assay at day 1, 3, 7, and 14. Meanwhile, the behavioral score was determined. The expression of GAP43 in the hippocampal CA1 region was detected using Western blot at day 14.
RESULTSCompared with the control group, the expression of GAP43 increased in the model group, the behavioral score was elevated, degenerated neurons increased, and survival neurons decreased in the model group (all P < 0.05). Compared with the model group, the expression of GAP-43 increased (with the most significant difference seen in the group C, P < 0.01), the behavioral score significantly decreased, degenerated neurons decreased, and survival neurons increased in each HSC group (all P < 0.05). Survival neurons obviously increased at day 14, of which, most number of survival neurons and highest contents of GAP43 protein could be seen in the group C, showing statistical difference when compared with those of the group A and the group B (P < 0.01).
CONCLUSIONSHC had protective effect on total cerebral IR in the hippocampal CA1, which might be associated with increased expression of GAP43.

Background Dacryocystitis is one of the most common infectious eye diseases.The gold standard for the identification of bacteria causing dacryocystitis is bacterial culture.The combination of regular culture method with molecular biology techeniques will generate more reliable results.However,very few research data are available in ophthalmological studies in this area.Objective This study was to identify the genera and species of the dacryocystitis-causing bacteria by PCR amplification of the 16S rRNA sequences.Methods Ten cases of qualified standardized bacteria samples were taken,and the nucleic acids were released in the heating process of the PCR procedure.The 16S rRNA genes were amplified and sequenced,and the genera and species were identified using BLAST from GenBank,and the results were used to compare with the results from biochemical identification to test the reliability of this method.The cultured bacterial species from the lacrimal sac secretions from 30 cases of dacryocystitis patients were identified with the above method.Results The outcome of the PCR identification for the 10 cases of quality control standard bacterial specimens was consistent with the results from the biochemical identification.The identification of the 30 cases of dacryocystitis through sequencing the 16S rRNA revealed there were 13 cases of Staphylococcus epidermidis infection,2 cases of Staphylococcus warneri infection,1 case of Staphylococcus hominis infection,5 cases of Corynebacterium macginleyi infection,3 cases of Streptococcus pneumonia infection,2 cases of Bacillus cereus infection,1 case of Micrococcus luteus infection,1 case of Moraxella catarrhalis infection,1 case of Moraxella osloensis infection and 1 case of Pseudomonas aeruginosa infection.Conclusions Sequencing the 16S rRNA is an accurate and specific way for the identification of the genera and species of bacteria that cause dacryocystitis in patients.This sequencing method is feasible in monitoring a variety of dacryocystitis-causing pathogens.More information and epidemiological statistics about dacryocystitis can be obtained from 16S rRNA sequencing.
