Aim To quantitatively analyze the lymphocyte proliferation using the time-series data of carboxyfluorescein diacetate succinimidyl ester(CFSE).Methods The model of immune suppression in mice was created by cyclophosphamide and CFSE dye was used for staining the lymphocyte of both control group and treatment group animals. The data were analyzed through mathematical model-fitting.Results The first generation of cell proliferation of the control group and treatment group were 27.17 h and 22.88 h; cell death rates in each division were respectively 20% and 40%; the half-life of cells before the proliferation was respectively 31.53 h and 43.32 h.Conclusions The mathematical fitting of CFSE data can quantitatively analyze the mechanism of the drugs attecting the proliferation of lymphocyte.In this experiment the mechanism of cyclophosphamide inhibiting lymphocyte proliferation may be due to the increase of cell death rate of each division caused by cyclophosphamide.

Objective To find the source of CA 125 in serum and the values of the expression of CA125 in serum, ascites and tissue in patients with epithelial ovarian cancer. Methods Detected the expression of CA125 in the primary lesions of epithelial ovarian cancer and the metastasis in abdominopelvic cavity (peritoneal and omental metastatic lesions) by S-P immunohistochemical methods. Compared the expression of CA 125 in tuberculose focus and acute inflammation focus in abdominopelvic cavity and detected CA125 in serum and ascites by ELISA. Results The levels of CA125 in serum of the patients with epithelial ovarian cancer [(523.66±158.02)kU/L],benign epithelial ovarian tumor [(138.11±26.52)kU/L] and tuberculosis of abdominopelvie cavity [(486.56±147.10)kU/L] were higher than that with the normal ovary [(17.48±3.37)kU/L], and there were significant differences (P<0.05).The levels of CA125 in serum of the patients with epithelial ovarian cancer and tuberculosis of abdominopelvic cavity were significantly higher than that with benign epithelial ovarian tumor, and there were significant differenees (P<0.01). The levels of CA125 in ascites of the patients with epithelial ovarian cancer [(996.85±337.87)kU/L] and tuberculosis of abdominopelvic cavity [(596.78±197.10)kU/L] were higher than that with benign epithelial ovarian tumor [(179.48±63.08)kU/L] and normal ovary [(177.70±51.72)kU/L], and there were significant differences (P<0.01).The level of CA125 in ascites of the patients with epithelial ovarian cancer was higher than that with tuberculosis of abdominopelvic cavity, and there was significant difference (P<0.01). By correlation analysis, the relationship of the level of CA 125 in serum and in ascites of the patients with epithelial ovarian cancer was positive correlation(r=0.687). Conclusion Besides the original and metastatie lesions (greater omenta and peritoneum) of epithelial ovarian cancer can express CA 125, the second Maller canal, for example the peritoneum mesothelial cell can be stimulated to express CA125 by ascites, which results in the increase of CA125 in serum.

Using the weight-average molecular weight 50 000 polylactic acid (PLA) as a carrier, and a certain proportion of erythromycin (EM) and prednisone acetate (PNA) to mixed prepare the compound erythromycin sustained release preparation (sustained-release tablets). Using ultraviolet spectrophotometry and high performance liquid chromatography (HPLC) to detect separately the release amount of EM and PNA in vitro medium. The sustained-release tablets release for about 21 days, the average content of EM is 99.7 mg/table, RSD = 0.82%; and the average content of PNA is 10.03 mg/table, RSD = 0.93%. Within 21 days, the cumulative releases of EM and PNA are 86.1% and 78.3%, respectively. The drug release is steady and slow after 5 days, the burst release phenomenon in early stage is more significant. The results showed that the sustained-release tablet preparation method is feasible, the release performance is good and the clinical efficacy is significant.

Objective To explore the diagnostic values of dual energy lung perfusion in the diagnosis of pulmonary embolism by using dual-source CT (DSCT). Methods Thirty patients with clinically suspected pulmonary embolism underwent dual-energy scanning with dual-source CT. The scanned data were integrated into three groups including 140, 80 kV and coefficient of 0.3. According to the CT pulmonary angiography (CTPA) of the fusion data, the patients were divided into pulmonary embolism group and normal group. The thin-slice reconstruction of data was analyzed using dual-energy perfusion imaging analysis software. The lung field was divided into upper, middle and lower part to make quantitative analysis of lung tissue perfusion. Paired t-tests were used in the normal patients to compare bilateral lungs, and independent samples t-tests were applied to compare the embolism group and normal group, while minimum intensity projection images (MinIP) were utilized in the assessment of lung ventilation. Results Dual energy CT showed symmetrical homogeneous perfusion in 16 normal cases, without significant perfusion defects. Quantitative analysis showed that left and right lung perfusion were (27 ± 7) and (28 ± 8 ) HU respectively, and no significant difference was found between the two sides ( t=-1.73, P >0.05 ).Perfusion of the left upper, middle and lower lung was ( 23 ± 6), (24 ± 6), and (28 ± 8) HU respectively, while the perfusion of right upper, middle and lower lung was (26 ±8), (27 ±8), and (28 ±9) HU respectively, showing no statistical significant difference between the two sides (t=-1.91, -1.96,-1.73 ,P>0.05 ). Angiography of pulmonary embolism group(14 cases)showed filling defects in the pulmonary trunk, segments and sub-segments. Pulmonary perfusion imaging showed low perfusion or defectsin lung field that dominated by embolic vessels. Quantitative analysis showed that the perfusion of the whole lung and the middle and lower lung were (22 ±5), (22 ±8), and (21 ±8) HU in the embolism group,which were significantly different from the normal group (t=-2. 10, -2.32, -2.63, P<0.05).Minimum intensity projection images showed a good consistency of abnormal ventilation zone area and perfusion abnormalities. Conclusions Pulmonary perfusion status, especially pulmonary embolism, can be analyzed by dual energy CT scanning. It helps to early discover and precisely locate the embolism.

Objective To study the gait footprint parameters of the normal children and the cerebral palsy (CP) children, and to explore its clinical value. Methods A total of 2 800 normal children aged 3 to 10 years and 139 spastic CP children aged 3 to 5 years were recruited in this study. The normal children were divided into seven groups with one year interval, and were measured with regard to the length of foot and step, step width and foot angle of footprint of every age group with self made oil printed carpet. The footprint of the CP children were measured and compared with that of the normal children at the same age. Results It was revealed that there was significant difference between the normal and the CP children ( P
