Objective:To investigate the efficacy of magnesium sulfate combined with labetalol on severe preeclampsia and the effects on serum levels of soluble intercellular adhesion molecule-1 (sICAM-1), vascular endothelial growth factor (VEGF) and pregnancy associated plasma protein-A (PAPP-A).Methods:Eighty-five patients with severe preeclampsia who received treatment in Jinhua Municipal Central Hospital between January 2019 and June 2020 were included in this study. They were randomly assigned to receive treatment either with magnesium sulfate (control group, n = 42) or magnesium sulfate combined with labetalol (observation group, n = 43). Before and after treatment, 24-hour dynamic blood pressure, 24-hour urinary protein excretion and umbilical artery hemodynamics were determined. In addition, serum levels of sICAM-1, VEGF and PAPP-A were detected. Results:After treatment, 24-hour mean arterial pressure, 24-hour urine protein excretion in the control and observation groups were significantly decreased compared with before treatment. After treatment, the 24-hour mean arterial pressure [(116.45 ± 9.63) mmHg vs. (120.74 ± 9.48) mmHg] and 24-hour urine protein excretion [(1.85 ± 0.52) g vs. (2.33 ± 0.75) g] were significantly lower than those in the control group ( t = 2.069, 3.436, both P < 0.05). The umbilical artery resistance index in the control group, and the peak systolic velocity/end-diastolic velocity ratio and the umbilical artery resistance index in the observation group were significantly decreased after treatment compared with before treatment (all P < 0.05). After treatment, the peak systolic velocity/end-diastolic velocity ratio in the observation group was significantly lower than that in the control group [(2.80 ± 0.50) vs. (3.01 ± 0.45), t = 2.034, P < 0.05]. After treatment, serum sICAM-1 and PAPP-A levels were significantly decreased, and serum VEGF level was significantly increased, in each group (all P < 0.05). After treatment, serum levels of sICAM-1 [(548.52 ± 102.74) mg/L vs. (647.52 ± 124.15) mg/L, t = 4.009, P < 0.05] and PAPP-A [(111.74 ± 28.52) U/L vs. (134.24 ± 35.96) U/L, t = 3.200, P < 0.05] in the observation group were significantly lower than those in the control group, and serum VEGF level in the observation group was significantly higher than that in the control group [(32.12 ± 7.45) ng/L vs. (28.17 ± 6.23) ng/L, t =2.659, P < 0.05]. There was no significant difference in the incidence of poor pregnancy outcome between the control and study groups ( P > 0.05). Conclusion:Magnesium sulfate combined with labetalol exhibits good therapeutic effects on severe preeclampsia. The treatment method can improve umbilical artery hemodynamics, and its mechanism may be related to its effect on vascular endothelial function.

Objective: To evaluate the efficacy of 3LL/GM-CSF tumor vaccine combined with pacilitaxel chemotherapy in treatment of mice bearing transplanted Lewis lung carcinoma. Methods: The tumor vaccine 3LL/GM-CSF was prepared by infecting Lewis lung carcinoma cell line 3LL with adenovirus encoding GM-GSF. Mice model of Lewis lung carcinoma was established by subcutaneous injection of 2?104 3LL cells into C57BL/6(H-2b)mice. The sensitivity of Lewis lung carcinoma cell line-3LL to the treatment of pacilitaxel was detected in vivo and in vitro. The mice tumor model was first treated with pacilitaxel chemotherapy and then with 3LL/GM-CSF, or first with 3LL/GM-CSF and then with pacilitaxel. Tumor growth and the long-term survival of mice were observed after treatment. The immune memory and cytotoxicity against target cells were studied in the mice. Results: Pacilitaxel at 100 nmol/L killed 32.10% 3LL cells after 24 hour in vitro; but pacilitaxel at 5-25 mg/kg only had a poor effect on growth of 3LL cells in vivo. The tumors rebated in 70% of mice treated with pacilitaxel chemotherapy and 3LL/GM-CSF vaccination successively, and the survival of these mice was obviously longer than that of pure pacilitaxel chemotherapy group (70.0 days vs 27.5 days). The killing rate of 3LL/GM-CSF after pacilitaxel chemotherapy was 41.35% on day 3. Meanwhile, the survival mice could resist the re-attack of 3LL cells (2?104). We also noticed that first treatment with 3LL/GM-CSF and then pacilitaxel chemotherapy had no effect on tumors. Conclusion: Application of tumor vaccine shortly after pacilitaxel chemotherapy can induce specific immune responses and prolong the survival of experimental mice, which provide a basis for future clinical practice.
