ABSTRACT
Objective:To investigate Shenqi Fuzheng Injection combined with nimodipine in the treatment of convalescent-phase cerebral infarction and its effects on neurocognitive function, hemorheology and T cell subsets. Methods:A total of 108 patients with cerebral infarction in the convalescent phase who received treatment in Hangzhou Hospital of Traditional Chinese Medicine, China between April 2016 and December 2019 were included in this study. They were randomly assigned to receive either nimodipine treatment (control group, n = 54) or treatment with Shenqi Fuzheng Injection combined with nimodipine (study group, n = 54). Curative effects and changes in neurocognitive function, hemorheology and T cell subsets after treatment relative to before treatment were compared between the control and study groups. Results:Total effective rate in the study group was significantly higher than that in the control group [90.74% (49/54) vs. 75.93% (41/54), χ2 = 4.267, P = 0.039]. After 2 weeks of treatment, whole blood viscosity at a high shear rate, whole blood viscosity at a low shear rate, plasma viscosity in the study group were (4.17 ± 0.24) mPa/s, (9.27 ± 1.98) mPa/s, (1.07 ± 0.19) mPa/s, respectively, which were significantly lower than those in the control group [(4.52 ± 0.31) mPa/s, (13.69 ± 2.13) mPa/s, (1.34 ± 0.23) mPa/s, t = 6.560, 11.169, 6.651, all P < 0.05]. The proportion of CD 3+ cells, CD 4+ and CD 4+/CD 8+ in the study group was (48.59 ± 4.59) %, (44.24 ± 6.17) % and (1.91 ± 0.17) respectively, which were significantly higher than those in the control group [(44.97 ± 5.31) %, (39.55 ± 5.13) %, (1.47 ± 0.22), t = 3.790, 4.295, 11.629, all P < 0.05]. The proportion of CD 8+ cells in the study group was significantly lower than that in the control group [(23.13 ± 5.62) % vs. (26.97 ± 4.26) %, t = 4.001, P < 0.05]. Mini-Mental State Examination score in the study group was significantly higher than that in the control group [(28.87 ± 0.85) points vs. (27.91 ± 1.45) points, t = 4.197, P < 0.05]. National Institute Health of Stroke Scale score in the study group was significantly lower than that in the control group [(9.63 ± 2.19) points vs. (15.27 ± 1.97) points, t = 14.070, P < 0.05]. Conclusion:Shenqi Fuzheng Injection combined with nimodipine can remarkably improve the neurocognitive function, hemorheology and T cell subsets in patients with cerebral infarction in the convalescent phase. The combined method is safe and reliable, and its curative effect is stable.
ABSTRACT
Objective To investigate the expressions of KLF2 mRNA and KLF4 mRNA in the acute lung injury (ALl) rats induced by lipopolysaccharide (LPS),and to analyze the correlation between KLF2,KLF4 and ALI.Methods A total of 100 SD rats were randomly divided into 2 groups:normal control group and LPS treated group,then the latter group was randomly further divided into 3 subgroups as per the serum and lung tissue samples taken separately at 2,4 and 24h after modeling.The ALI model was made by injecting 5mg/kg LPS into tail vein.The pathological changes of lung tissue were observed in each group,and the expressions of KLF2,KLF4 mRNA in serum and lung tissue were detected by RT-PCR.The data of laboratory findings were analyzed with SPSS 17.0 software for statistical analysis.Results The histopathological changes showed the most obvious damage of lung tissue occurred at 4 hours after modeling.The expressions of KLF2 mRNA and KLF4 mRNA in the lung tissue and serum of control group were significantly higher compared to LPS treated subgroups (P ＜0.01).The expression of KLF2 mRNA in LPS treated subgroup at 2 hours was lower than that in LPS subgroups at 4 hours and 24 hours (P ＜ 0.01),while the expression of KLF4 mRNA in LPS treated subgroup at 4 hours was lower than that in LPS treated subgroups at 2 hours and 24 hours (P ＜ 0.01).Conclusions The expression of KLF2 mRNA was occurred earlier than the pathological changes in acute lung injury,while the expression of KLF4 was emerged synchronously,and both KLF2 and KLF4 could be used as candidates of predictive and diagnostics molecular markers of ALI.
