Objective To investigate the effects of terazosin on expressions of matrix metalloproteinase-9 (MMP-9) and monocyte chemotactic protein 1 (MCP-1) in a rat model of atherosclerosis and to explore the mecha-nism for reducing atherosclerosis by terazosin. Methods Normal rats were fed with high lipid feedstuff to set up a rat model of atherosclerosis. Blood lipid indexes were measured and the expressions of MMP-9 and MCP-1 in aorta were detected and further quantified by immunohistochemistry after 12-week high lipid feedstuff. Results The plasma concentration of TG, TC, LDL in the terazosin group were significantly lower than those in the high cholesterol-diet group (P<0.01). The expressions of MMP-9 and MCP-1 in the high cholesterol-diet group and in the terazosin group were significantly higher than those in the normal-diet group (P < 0.01), but expressions of MMP-9 and MCP-1 in the terazosin group were significantly lower than those in the high cholesterol-diet group (P<0.01). Conclusion Terazosin can lower the concentration of TC, LDL but increase the HDL concentration. The anti-atherosclerotic mechanism of terazosin is associated with the decrease of the expressions of MMP-9 and MCP-1 and plasma lipoprotein.

BACKGROUND: In a series of recent studies it was demonstrated thatpolysaccharides play important roles in many physiologic and pathologicprocessions, such as infection, inflammation, inter-cell adherence and sig nal conduction, immune identification, cell proliferation and differentiation, as well as maintenance of cell structure and function. But the protectiveeffect of plant polysaccharides on gastrointestinal mucosa needs further re search. OBJECTIVE: To observe the effect of the total polysaccharides of SijunziDecoction (SJZD) (TPSJ) in different concentrations on the proliferation ofrat intestinal epithelial cell line IEC-6. DESIGN: Observational controlled trial. SETTING: Central Laboratory, Guangdong Hospital of Traditional ChineseMedicine. MATERIALS: ①Cell line: The IEC-6 of normal rats (Catalog No. RL 1592) was purchased from American Type Culture Collection (ATCC). IEC6 cells were originated mainly from intestinal crypt cells. ②Reagents anddrugs: DMEM medium, bovine insulin, gentamicin, fetal bovine serum (FBS) and DPBS were purchased from GIBCO Ltd. Cell proliferation kit(MTT) was purchased from Roche Ltd. Indomethacin was purchased fromSigma Company. SJZD was composed of Dangshen (Codonopsis pilosula),Baizhu (Atractylodes macrocephala), Fuling (Poria cocos) and Gancao (Glycyrrhizae uralensis), and these four drugs were in same ratio as Pharmacopoeia. The four herbs were boiled in water, extracted twice for 8 hours.Extract was combined, decompressed, concentrated, centrifugated with high speed to take out insoluble substance, put in glass paper to receive reverse lotic water dialysis for 2 hours. The final decoction was concentrated by heating followed by extraction with 80% ethanol. After overnight precipitation at room temperature and combination of sedimen, the total polysaccharide was obtained by deproteinating with the Sevag method.METHODS: ①The IEC-6 cell line was maintained in T-150 flasks with DMEM culture solution, and then put in CO2 incubator at 37 ℃, at saturated humidity, cultured at 0.05 volume fraction CO2, after being taken out from dry ice and defrosted rapidly in water-bath at 37 ℃. Flasks were incubated at 37 ℃ in 5% CO2· Stock cells were subcultured at a dilution of1:7 every 5-7 days and the medium was changed once every 2 days. The cells in passage 15-20 were used for testing. ②IEC-6 cells were inoculated at a density of 1×l04 cells/well in 96-well plates. Cultured were supplemented with TPSJ in a final concentrations ranging from 50, 100 and 200 mg/L after 6 hours, which was 3 TPSJ groups. One plate would be taken out for the examination of cell proliferation using MTT assay everyday. The cells that not administrated by any intervention were used as normal control group and cell proliferation was assayed using MTF at corresponding time points. ③IEC-6 cells were inoculated at a density of1×104 cells/well in 96-well plates, and then cultured in the DMEM supplemented with no serum from the following day for 24 hours. For the examiation of mucosal restitution, indomethacin at concentration of 40 mmol/L was employed to induce IEC-6 cells injured, which was indomethacin group. The three concentration of TPSJ was 50, 100 and 200 mg/L, respectively, which was 50,100,200 mg/L TPSJ groups. After drug action for 20 hours, the proliferation of cells was measured using MTT according to the manufacturer's instructions. IEC-cells without any intervention were used in the normal control group. Cell proliferation was determined with TT method at corresponding time points.MAIN OUTCOME MEASURES: MTT assay was used to examine the effects of TPSJ on IEC-6 cell proliferation in different times. MTT assay was used to detect the effect of TPSJ on IEC-6 cell proliferation inhibited by indomethacin.RESULTS: TPSJ could accelerate IEC-6 cells growth at different doses and in different time. After the cells were treated by 40 mmol/L indomethacin for 24 hours, the absorbance (A) of IEC-6 cells apparently declined compared with that in the normal control group (0.17±0.02,0.31±0.03; P < 0.01). The A of IEC-6 cells treated by TPSJ in 100 mg/L group was apparently higher compared with indomechacin group (0.25±0.04, 0.17±0.02; P < 0.01). The A of IEC-6 cells treated by TPSJ did not restored to the normal level, but there was no insignificant difference compared with normal group (P > 0.05).CONCLUSION: TPSJ can accelerate the proliferation of IEC-6 cells. TPSJ can exert regulatory function both in intestinal mucosa absorption and immunity by affecting intestinal epithelial cells.

Objective To evaluate the feasibility and application of histopathology diagnosis of endometrial tissues obtained by endometrial cell collector (Jingyou, SAP-1). Methods One hundred and ninety-three patients whose endometrial lesions should be excluded were selected. First, endometrial tissue were obtained from the patients by Jingyou, then they underwent comprehensive curettage under hysteroscopy. The histopathology diagnosis was performed respectively. The specimen satisfaction rate and diagnostic accuracy was analyzed and compared. Results The specimen satisfaction rate of curettage under hysteroscopy was 95.85%(185/193). The specimens of 8 cases were not satisfied because the tissues were not enough. The specimen satisfaction rate of Jingyou was 82.38% (159/193). The specimens of 34 cases were not satisfied, among whom in 10 cases scratches did not throughout the whole palace antrum, and in 24 cases tissues quality were poor. The endometrial thickness in unsatisfactory specimen by Jinyou was significantly thinner than that in satisfactory specimen:(0.64 ± 0.18) cm vs. (0.97 ± 0.43) cm, and there was statistical difference (P<0.05). The diagnostic accordance rate between Jingyou and curettage under hysteroscopy was 79.87%(127/159). The sensitivity of Jingyou from high to low was 94.19% (81/86) in normal menstrual endometrial, 7/10 in endometrial carcinoma/ atypical hyperplasia, 67.86%(38/56) in endometrial hyperplasia and 1/7 in endometrial polyps. Missed diagnosis of jingyou inluded 2 cases of endometrial carcinoma and 4 cases of endometrial atypical hyperplasia. The misdiagnosed rate of high grade endometrial lesions was 6/16, and the patients were misdiagnosed because the tissues were not enough. Four cases of endometrial atypical hyperplasia had underwent conservative treatment of repeated curettage. Conclusions Application of Jingyou can obtain micro endometrial tissues, and the accordance rate of histopathology diagnosis is high with curettage under hysteroscopy. When the collector makes a comprehensive collection to the uterine cavity specimen, it can accurately screen endometrial carcinoma and atypical hyperplasia. The patients who have endometrial atypical hyperplasia and receive conservative treatment and curettage repeatedly curettage, thin endometrium and ultrasonic highly suspected endometrial polyps, are not recommend to use Jingyou to obtain specimen. When the specimen is not satisfied using the collector, additional hysteroscopy should be performed to avoid misdiagnosis of high grade endometrial lesions.
