The effects of butyric acid on cloned human lung cancer cells (PLA-801D) were observed with flow cytometry (FCM) and the conventional methods to identify the biological characteristics of cell lines. Butyric acid ( 2 or 3 mmol/L)treatment could result in an inhibition of the cell division and the growth rate of the cells,the blocking of the cell cycle progression in the Gl phase,a prolongation in doubling time, a shortening in saturation time, a decrease of saturation densities,and a reduction of plating efficiency. At the same time,there were some normal phenotypes of the cells such as flattening, tendency to grow in a monolayer,weakening of surface membrane activities, regularization of nuclei, and increasing of intercellular junctions.These findings suggest that after the treatment of butyric acid, the cancer cells (PLA-801D) appeared to acquire relatively normal growth properties and phenotypes. Thus, butyric acid, to a certain extent, can induce differentiation of PLA-801D cells, and be a potential anticancer agent.

[Objective] To explore the clinical effect of Buyang Huangwu Decoction and Guipi Decoction together on BTS. [Method] Select 48 cases of BTS in accordance of diagnosis standard, divide them into treatment group 48 cases(take revised Buyang Huangwu Decoction and Guipi Decoction ) and control one 20(routine western medicine), judge their cure effect after 2~4 courses. [Result] The cure rate and total effective rate were respectively 60.42%and 87.50% for treament group, for control one, they were respectively 30.00% and 65.00%; with χ2 test, their differences were respectively of marked statistical meaning and statistical meaning. [Conclusion] Buyang Huangwu Decoction and Guipi Decoction together had definite cure effect on BTS.

Objective To evaluate the imaging features of ulcer-like projections (ULP)and penetrating atherosclerotic ulcers (PAU)of intramural hematoma(IMH)using dual-source CT (DSCT).Methods Retrospectively analysis of DSCT imaging data of 1 12 patients in our hospital was performed.The shape of hematoma and location of ULP and PAU were evaluated Stanford A and B IMH depicting on DSCT images.The maximum diameter of aorta,maximum thickness of hematoma,deepness of ulcer were com-pared between in patients of IMH with or without ULP and PAU.Results IMH manifested as circular or crescent high density on plain scan and without contrast enhancement on DSCT images in 1 12 cases.Among of them,68 cases(68/1 12,61%)of IMH had ULP or PAU,in which there were 21 cases(21/1 12,1 9%)with ULP and 47 cases(47/1 12,42%)with PAU,the mean maximum depth was (0.48±0.1 5)cm in ULP and (1.08±0.56)cm in PAU.There were 4 cases with ULP and 9 cases with PAU in 29 cases of Stanford type A,while 1 7 cases with ULP and 38 cases with PAU in 83 cases of Stanford type B.There were 14 cases with single ULP and 7 cases with multiple ULP in 21 patients with ULP,while there were 27 cases with single PAU and 20 cases with multiple PAU in 47 patients with PAU.There were 1 9 cases with both PAU and ULP.There was statistical significance that PAU occurred more likely in the descending aorta and distal aorta than that in ULP (P =0.028).Conclusion IMH patients are susceptible to ULP and PAU,DSCT can objectively evaluate CT features of ULP and PAU of IMH.

In order to verify the origin relations of Zhouhou Emergency and modern clinical medicine in emergency treatments,we choose Zhouhou Emergency as study object,and try to verify four treatments including artificial respiration,urethral catheterization,surgical infection and hemostasis. Through tracing back to the initiation and developing history of modern medical technique,it fixes its position in modern emergency treatments,and affirms the important roll of Chinese ancient books in promoting the techniques of modern emergency science.

在地震中,颅脑外伤极为常见,其救治过程特点为:发生突然、时间急、伤员多、伤情复杂、抢救难度大。治疗细节决定救治的成败。在早期治疗中,主要是维持生命体征,为原发性脑损伤提供恢复条件,避免继发性脑损伤。尽早转运到后方专科医院治疗,减少死亡及伤残率。

To observe the changes of interferon-γ (IFN-γ) and interleukin-4 (IL-4), factors related to T helper 1/T helper 2 (Th1/Th2), in airway inflammation in an asthmatic model of mice and the effects of Pingchuan Formula (PCF), a compound traditional Chinese herbal medicine.

ObjectiveTo investigate the expression of heme oxygenase-1 (HO-1) in lung tissue of mice with acute paraquat poisoning, and discuss its pathological mechanism.Methods Fifty-eight healthy male mice were randomly divided into control group (n = 8) and poisoned group (n = 50). The mice in poisoned group were lavaged with 20% paraquat (50 mg/kg), and those in control group with equal amount of normal saline. The mice were sacrificed on the day of experiment in control group, and those in poisoned group at 6 hours and 1, 3, 7, 14 days after poisoning. The lung tissue was harvested to observe the changes in pathology of lung with hematoxylin and eosin (HE) staining. The positive expression of HO-1 was determined with immunohistochemistry, and the protein expression of HO-1 was determined with Western Blot. The contents of superoxide dismutase (SOD) and malonaldehyde (MDA) were determined.Results The mice showed shortness of breath and signs of exhaustion 1 hour after poisoning, getting worse on 3-5 days, but returned to normal 14 days after poisoning. Under the light microscope, it showed that the control group had no significant pathological changes in lung tissue. One day after the ingestion, pulmonary alveolar structure disorder, obvious hemorrhage, edema and infiltration of inflammatory cells were found. At 3 days, the pathological changes in the lung tissue were more pronounced. They were less pronounced on 7 days, and inflammatory changes disappeared on 14th day, but alveolar structure disorder remained. Immunohistochemical test showed that HO-1 was seldom expressed in the lung tissue, and a little amount was expressed in the mucosal epithelial cells of the airway in control group. It was shown that inflammatory cell and endothelial were mainly distributed in the mucosal epithelial cells of airway 1 day after poisoning followed by a gradually decrease tendence, and came to normal level of control group 7 days after poisoning. It was shown by Western Blot that HO-1 (gray value) in lung tissue increased 6 hours after poisoning (2.438±0.467 vs. 0.475±0.167,P< 0.01), peaked at 1 day (9.200±0.940 vs. 0.475±0.167,P< 0.01), continued to increase till 7 days after poisoning, and it lowered to normal level thereafter (0.825±0.260 vs. 0.475±0.167,P> 0.05). The SOD activity (μU/L) in lung tissue was lowered 6 hours after poisoning, and it was significantly lower than that of control group (649.681±13.951 vs. 1 167.051±15.744,P< 0.01), and it continued to decrease up to 14 days after poisoning (859.733±121.079 vs. 1 167.051±14.744,P< 0.01). MDA content (μmol/L) in the lung tissue homogenate was elevated 6 hours after poisoning with significant difference compared with that of the control group (4.542±0.266 vs. 3.705±0.176,P< 0.01). It peaked on day 1 (5.956±0.281 vs. 3.705±0.176,P< 0.01), then it declined and reached normal level 3 days after poisoning (4.134±0.168 vs. 3.705±0.176,P> 0.05).Conclusion HO-1 expression was increased significantly in lung tissue of mice with acute paraquat poisoning, which may be considered as an important protection mechanism against paraquat poisoning.
