ABSTRACT
Objective To investigate the feasibility of self-made capacitation liquid for in vitro fertilization of Mongolian gerbils, and to provide a reference for gerbil embryo cryopreservation. Methods In vitro fertilization of Mongo?lian gerbil was performed with the self?prepared capacitation solution and semen, and the 2?cell embryos of Mongolian ger?bils were cultured in vitro using an improved KSOM culture medium. Results The in vitro fertilization rate of gerbils was over 60%, and some gerbil 2?cell embryos could develop further in vitro. Conclusions An in vitro fertilization and embry?o development system of Mongolian gerbil has been established, but it needs further optimization.
ABSTRACT
Objective To study the intra-articular injection of tranexamic acid combined with drainage effectiveness and safety of clamping 6 hour program of perioperative blood loss of primary total knee replacement patients. Methods 76 cases of unilateral total knee replacement in our hospital for the study. In the control group, Sodium Chloride Solution was injected into the joint cavity to keep the drainage tube open. The experimental group underwent intra-articular injection of tranexamic acid combined with drainage clamping 6 hour treatment. The total blood loss and complications of the experimental group and the control group were compared and analyzed. Results There were no serious adverse reactions in the experimental group and the control group, the incidence rate was 5.26% and 7.89% respectively, and there was no significant difference (P<0.05). The total blood loss in the experimental group was (526.78 ± 229.09) mL, significantly less than that in the control group, and the total blood loss was (879.03 ± 246.80) mL, with statistical difference (P<0.05). The postoperative blood loss in the control group was (489.08 ± 267.80) mL, and the postoperative blood loss in the experimental group was (287.90 ± 245.78) mL, the difference was statistically significant (P<0.05). On the 7 day after operation, the patients in the experimental group and the control group received venous color Doppler ultrasonography, but no venous thrombosis was found. Conclusion The intra-articular injection of tranexamic acid combined with drainage clamping 6 hour scheme in reducing the initial application of patients with single knee arthroplasty, the clinical effect is ideal, can significantly reduce blood loss, high safety, has clinical significance.
