Objective To explore the expression of CD14 and TLR4 ( Toll like receptor - 4) in peripheral blood monocytes during the different stage of cancer patients. Methods The expression of TLR4 and CD14 on peripheral blood monocytes was determined by flow cytometry in 50 healthy control group and 80 patients with malignant tumor who were divided into stable group and advanced group according to the change of the size of tumor measured by image and/or the outcome of tumor makers. Results No significant difference was found in the expression level of CD14 between the different stage of malignant tumor ( stable group and advanced group) and healthy controls [ (6. 1600% ? 2. 32217% ,5. 8629% ? 1. 91896% ) vs (5. 5580% ? 1. 42272% ) ]. The expression of TLR4 in stable group had no significant difference as compared with control group [ ( 10. 4444 ? 3. 16225 ) % vs (8. 8780 ? 5. 24612) % ]. The expression of TLR4 in advanced group was significantly higher than that in controls and stable group [ ( 14. 7286 ? 6. 95213 ) % vs ( (8. 8780 ? 5. 24612) % , ( 10. 4444 ? 3. 16225) % ) (P

Objective:To evaluate the nasal safety of gastrodin nasal temperature-sensitive in situ gel through the studies on cilia toxicity in toads and mucosal irritation in rats. Methods:The toads were randomly divided into four groups, saline group, gastrodin in situ gel group, blank gel matrix group and sodium deoxycholate group, and the cilia toxicity was observed in vivo by a toad palate meth-od. The rats were randomly divided into three groups, saline group, gastrodin in situ gel group and blank gel matrix group, and the mucosal irritation was studied in rats through the observation of nasal mucosal pathological changes and behavioral indices. Results:Compared with the saline group, gastrodin in situ and blank gel matrix showed no notable effect on the cilia movement function in toads, and the effect on cilia movement of sodium deoxycholate showed statistically significant difference when compared with that of sa-line, gastrodin in situ gel and blank gel matrix (P<0. 01). During and after the treatment, no sneezing appeared in the rats. Com-pared with that in the saline group, the number of scratching nose in the gastrodin in situ gel group and blank gel matrix group in-creased (P<0. 05) without difference between the groups (P>0. 05), and after the 2-day withdrawal, that in the gastrodin in situ gel group and blank gel matrix group decreased significantly when compared with that at the last administration (P<0. 05) and showed no notable difference when compared with that in the saline group (P>0. 05). The number of inflammatory cells in the nasal mucosa in the gastrodin in situ gel group and blank gel matrix group increased complicated with congestion and cilia falling off, and after the with-drawal, the mucosal morphology in the three groups showed no significant difference. Conclusion:The local application of gastrodin in situ gel has high security, which is valuable to be studied further.

Objective To detect chromosome translocation t (11;18)(q21;q21) and expression of BCL10 protein in gastric mucosa associated lymphoid tissue (MALT) lymphoma. Methods We, combining clinical and pathological data, detected API2 MLT fusion by reverse transcriptase polymerase chain reaction (RT PCR)as well as the expressions of BCL10 protein and Ki 67 by immunohistochemistry in cases of gastric MALT lymphoma and follicular gastritis (FG) and analyzed the relationships among them. Results API2 MLT fusion was detected in three cases (2 low grade and 1 low to high grade) out of 14 cases of gastric MALT lymphoma, and no in 8 cases of FG. BCL10 protein was weakly expressed in cytoplasm of B cells of germinal center in lymph follicles of FG; but abundantly in cytoplasm of tumor cells in gastric MALT lymphoma; 42.5% of the latter showed weak expression in nucleus. The expression of Ki 67 was significantly higher in low to high and diffuse large B cell lymphoma cases than in low grade cases( P 0.05), the frequency of nuclear expression of BCL10 increased with the increased expression of Ki 67. Conclusions Both API2 MLT fusion and BCL10 nuclear expression are associated with transformation of gastric MALT lymphoma from LG to HG. RT PCR technique used to detect API2 MLT fusion may be an important tool in identification of t(11;18)(q21;q21).

Zishi township of Jiangling city is located in the canal area inside embankment,a heavy endemic area of schistosomiasis japonica in Hubei province. The population and cattle preva-lence was 29.5% and 66.7% respectively in 1992. There are 66 canals and it covered a total area of 300000m2. 97.0% of the canals and 99.3% of the total area had snail inhabitants, and 7.6% of the snails distributed in canal was infected which covered 18.3% of the total area. The snails were mainly distributed in the main canal and their branches. The rate of snail distribution was 45.2% and 39.8% respectively. Cattle was pastured all year round in this area. Examination of scattered cattle feces and water revealed that the major factor of water contamination was scattered cattle feces. It explained why the infection rate of snail was high and the distribution of infected snail was extensive and how the major high rise area inside embankment was formed.

Methods Twenty rats were randomly and equally divided into two groups: control group and experiment group. Each rat in the experiment group received an ip injection of 2 ml normal saline containing 1.5?10 6 tachyzoites of T. gondii . On the 64th day after injection of T.gondii , the changes in T lymphocytes (TL) and their subgroups, the helper T lymphocytes (Th) and the suppressor T lymphocytes(Ts) in the peripheral blood of the rats with T.gondii were determined by the assay of the lymphocytes labeled with intercellular acid ? naphthyl acetate esterase. All the rats were killed and the atomic absorption method were used for detecting the level of trace elements in the spleen tissue. Results The number of TL and Th in experiment group was significantly lower than that of control ( P

Objective To explore the clinical features of systemic onset of juvenile idiopathic arthritis (SoJIA) with atlantoaxial subluxation as the initial manifestation. Methods The clinical data from one SoJIA patient with atlantoaxial subluxation as the initial manifestation were retrospectively analyzed. Results A 9-year-old boy presented the head and neck movement disorder as the ifrst symptom, developed fever on the third day, then rapidly progressed on 23rd day, with a sharp decline in red blood cell, platelet, and hemoglobin, blood coagulation dysfunction, and a large number of bilateral pulmonary exudation. Ultrasonography showed excess lfuid in abdomen, chest, and pericardium. According to the 2001 version of the revised International College of Rheumatology standard, the diagnosis of SoJIA combined macrophage activation syndrome was conifrmed. Then treated with hemoperfusion, ifltration, and methylprednisolone combined with cyclosporine A, the disease was in remission. Conclusion For children with spontaneous atlantoaxial subluxation accompanied by the systemic symptoms, with no obvious skeletal deformity or acute inlfammation etc., should be alerted to the consideration of systemic juvenile idiopathic arthritis.
