OBJECTIVE Toinvestigatethedifferenceofcytotoxiceffectsofhydroxycamptothecin(HCPT)onhuman lungcancercelsA549andhumanembryolungfibroblastcelsMRC-5.METHODS A549celsandMRC-5celswere treated with HCPT 20-200 μmol·L-1 for 24,48 and 72 h,or pulse treated with HCPT 50-400 μmol·L-1 for 24 h along with 5 d release.cellsurvival was detected by MTT assay.Morphological changes for both types of cells were observed under an inverted phase-contrast microscope.cellcycle and apoptosis in both cells treated with HCPT 50 μmol·L-1 for 48 h weredeterminedbyflowcytometry.RESULTS HCPT20-200μmol·L-1inhibitedthesurvivalofbothcelsinaconcen-tration-dependent manner and more cytotoxicity was observed in A549 cells for 48 h.The concentration-effect correlation coefficient(r)of HCPT in A549 and MRC-5 cells for 48 h was 0.898 (P=0.015)and 0.996 (P=2.56E-5)respectively. The inhibition rates were significantly different between A549 and MRC-5 cells with treatment of HCPT 20,50,80,1 00, 1 60 and 200 μmol·L-1 for 48 h (P<0.05).The IC50 of HCPT on A549 and MRC-5 cells was (24.00 ±0.69)μmol·L-1 and (1 23.63 ±3.89)μmol·L-1 respectively,indicating that A549 cells were 5-fold more sensitive to HCPT than MRC-5 cells at 48 h.After exposure to HCPT 50 μmol·L-1 for 48 h,some A549 cells were rounded up and shrank dramatical y, and some cells underwent membrane blebbing or lysing while MRC-5 cells had no obvious changes.cellcycle and apop-tosis analysis showed that A549 cells were arrested at both S and G2/M phases and apoptosis occurred but MRC-5 cells were just arrested at S phase.In the recovery growth curve,the growth of A549 cells was inhibited to a larger extent than MRC-5 cells and the growth retardation stil existed for 24 h in both cells.The survival of MRC-5 cells was faster than that ofA549cels,althoughtherewasnocompleterecoveryineithercel.CONCLUSION A549celsaremoresensitiveto HCPT than MRC-5 cells due to the fact that HCPT induces cellcycle arrest at both S and G2/M phases and apoptosis in A549 cells,but only triggers S phase arrest in the MRC-5 cells.

Objective·To study the hemodynamic parameters of uterine at midluteal phase in patients with early recurrent spontaneous abortion (ERSA) and the effect of aspirin on them. Methods·Transvaginal color Doppler ultrasonography was used to measure the parameters of uterine blood flow and the endometrial thickness at midluteal phase of 271 women with ERSA (ERSA group) and 66 women without a history of recurrent spontaneous abortion (control group). Then ERSA group were administered with aspirin 50 mg/d orally for 2 months and other individualized treatment, and the effect of aspirin on parameters of uterine blood flow and the early pregnancy outcome of them were observed. Results·At midluteal phase, the endometrium was significantly thinner in ERSA group than that in control group. Pulsatility index (PI) of endometrial blood flow and mean PI (mPI), mean resistance index (mRI), and mean systolic/diastolic ratio value (mS/D) of uterine arteries were statistically significantly higher in ERSA group in comparison to control group (P<0.05). Following aspirin treatment, resistance to uterine blood flow reduced significantly in ERSA group (P=0.000), and the endometrial thickness increased in the patients with endometrial thickness less than 7 mm (P=0.000). Only 163 ERSA patients were re-examined by transvaginal color Doppler ultrasonography after aspirin treatment, among whom 136 women was pregnant after individualized treatment. Among these pregnant patients, 97 cases were pregnant for more than or equal to 12 weeks, while 10 cases aborted during the first 12 weeks, and the early pregnancy outcomes of the other 29 cases were still unclear. Conclusion·In comparison with normal fertile women, ERSA patients have significantly higher resistance to uterine blood flow and thinner endometrium. Aspirin can improve uterine blood perfusion, which improves early pregnancy outcome.
