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).

Objective To promote the development of oncologic nursing by establishing the accreditation standards for oncologic nursing professional training base.Methods In the early stage Delphi method was used to make a consultation with 21 experts for the construction of accreditation standards for oncologic nursing professional training base.Then the weights of each level was determined by using Analytic Hierarchy Process (AHP).Results Five first-level indicators were established,including oncologic nursing,clinical practice teaching staff,training management,the basic conditions of the department and the basic conditions of the hospital,their weights were 0.385 5,0.248 4,0.160 0,0.121 3 and 0.084 9.Conclusions The accreditation standards for oncologic nursing professional training base is constructed by AHP.It can make the accreditation standards more scientific and reliable to provide a quantitative basis for the review.

Objective:To study the differences of ventilation function in patients between chronic right heart failure secondary to pulmonary arterial hypertension and chronic whole heart failure secondary to left heart diseases.
Methods:A total of 102 patients with clinical stable chronic heart failure (CHF) were studied. The patients were divided into 2 groups:Whole heart failure (WHF) group, n=41 and Right heart failure (RHF) group, n=61. The ventilation function test at rest and cardiopulmonary exercise test (CPX) were conducted and compared between 2 groups.
Results: The rest ventilation function was similar between 2 groups. For CPX examination, compared with WHF group, RHF group had the lower peak minute ventilation (VE), higher anaerobic threshold and peak minute ventilation/CO2 production (VE/VCO2), higher peak dead space volume/tidal volume (VD/VT), all P<0.05.
Conclusion:At exercise condition, RHF patients had decreased ventilation function and ventilation index due to severe abnormality of ventilation/perfusion (V/Q).

F0.01(1,5)=16. 30,P0. 05). Conclusion Laboratory results thus suggest that infection intensity is related to snail size per se, whereas prevalence in the field is related to snail size only through the correlation between size and age. In addition, under these experimental conditions, infected snails were no larger than uninfected snails, so the gigantism snails observed in the field might not be attributable to Trichobilharzia-induced effect.

OBJECTIVE To investigate the distribution and drug resistance status to pathogens from urinary tract and offer scientific evidence for reasonable usage of antibiotics.METHODS Totally 389 isolates derived from infected urinary tract in mountain area of western Hubei Province from 2002 to 2005 were identified and antibiotic susceptibility test was performed.RESULTS Escherichia coli accounted for 66.1% ranking the first.The isolates were all susceptible to imipenem and vancomycin.The ratio of ESBLs in E.coli and Klebsiella pneumoniae was 23.7% and 25.9%,respectively.CONCLUSIONS The drug resistance rate in isolates derived from infected urinary tract of patients in mountain area was lower than in plain region of Hubei Province.

Objective To investigate the ecological habit and characteristics of Trichobilharzia cercariae in the Huaihe river system. Methods During June of 2002-May of 2003, Radix auricularia snails were collected monthly in Yaohe Fishery of the branch of the Huaihe River. The cercariae, released from the positive snails and collected by Shade Drop Bottle, were examined by direct press. Ducklings were infected by cercariae with different ages and examined for the infection by miracidia hatching method.Results The results showed a typical seasonal fluctuation in infection rate of the snails, i.e. the cercariae detection rate was 0.81% in July, 0.65% in June, 0.07%-0.26% in April, May, August, September and October respectively, with a significant difference (? 2=26.73, P

BACKGROUND:Studies about low-frequency pulsed electromagnetic fields interfering with bone marrow mesenchymal stem cells proliferation and differentiation are many, but the Raman spectra of single stem cells irradiated in electromagnetic fields analyzed by surface Raman spectroscopy analysis are rarely reported. OBJECTIVE:To compare the difference in Raman spectra of bone marrow mesenchymal stem cells with or with no irradiation of 3 000 Hz pulsed electromagnetic fields. METHODS:Bone marrow mesenchymal stem cells isolated from Sprague-Dawley rats were cultured and identified. Passage 3 cells were inoculated into 6-wel plates and divided into two groups:pulsed electromagnetic field irradiation group and blank control group. After cultured for 7 days, cells in the two groups were transferred to physiological saline, and 30 cells were randomly col ected from each group. Four Raman spectra were harvested from each celland the average relative intensity of Raman spectra was calculated and compared between two groups. RESULTS AND CONCLUSION:There were the same Raman peaks in the two groups, and the waveforms were basical y same in the two group based on the curve mapping by origin 7.0 software. The peak value in the irradiation group was decreased compared with the blank control group. Laser optical tweezers Raman spectroscopy can be applied to study the biochemical changes of a single stem cellat the molecular level. The Raman spectra of bone marrow mesenchymal stem cells irradiated by 3 000 Hz pulsed electromagnetic fields differ from those without irradiation, and the peak also lowered after irradiation.
