负压封闭引流联合输氧冲洗治疗骨科术后感染性伤口的研究

目的 探讨负压封闭引流联合输氧冲洗治疗骨科术后感染性伤口的临床效果,为研究骨科及相关外科术后感染性伤口方面提供参考。方法 选择2020年10月—2022年6月蚌埠医学院第二附属医院收治的骨科术后感染性伤口患者28例,按照随机数字表法分为实验组和对照组,每组各14例。对照组给予负压封闭引流联合生理盐水冲洗治疗;实验组在对照组基础上给予联合输氧冲洗治疗,2组分别于术前、术后5～10 d使用无菌伤口测量尺测量并计算创面肉芽组织覆盖率、伤口体积缩小率、创面愈合率及愈合时间、细菌清除率,之后视创面情况决定二期手术或重新填入(更换)敷料继续封闭引流,直至愈合。结果 干预5～10 d后,实验组肉芽组织覆盖率、体积缩小率、细菌清除率[(93.03±4.05)%、(42.92±9.20)%、(95.93±4.19)%]均高于对照组[(74.73±5.08)%、(35.18±9.46)%、(87.20±2.35)%],差异均有统计学意义(t=-10.535、-2.193、-6.796;均P<0.05);实验组治疗愈合率为85.71%(12/14),高于对照组的78.57%(11/14),差异无统计学...     

Effect of thyroid hormone level on the expression of synaptotagmin Ⅰ in adult rat hippocampus

Objective To observe the effect of different thyroid hormone level on the expression of synaptotagmin Ⅰ(Syt Ⅰ) in adult rat hippocampus. Methods All 28 adult male SD rats were assigned randomly into hypothyroid, hyperthyroid and control group, hypothyroid group was established by daily intraperitoneal injections with propylthiou raci(PTU, 10.0 mg/kg body weight) for 6 weeks and hyperthyroid group with L-Thyroxine (L-T4, 0.5 mg/kg body weight) for 3 weeks. Radioimmunity method was used to assay the levels of serum T3 and T4, immunohistochemical S-P technology to assay the levels of Syt Ⅰ protein in hippoeampus CA1, CA3 and dentate gyrus (DG). The layers analyzed in the different subfields include the polymorphic cell layer(the stratum oriens, SO), pyramidal cell layer(PCL), stratum radiatum (SR), lacunosum-molecular layer (SLM) in CA1 and CA3, granular cell layer(GL) and molecular layer(ML) in DG. Results The levels of serum T3 and T4[(0.34±0.12), (41.03± 11.37)nmol/L]in the hypothyroid rats were significantly lower than those in the control group[(0.65±0.15), (55.20±10.68)nmol/L, P < 0.01 or < 0.05], and the positive granule of Syt Ⅰ was significantly lower in PCL and SR of CA1 and CA3, GL of DG. The average optical value responsible for Syt Ⅰ immunoreactivity was obviously reduced in SO(0.048±0.007), PCL(0.299±0.035), SR(0.042±0.007), SLM(0.038±0.006) of CA1, PCL(0.085± 0.019), SR(0.040±0.011), SLM (0.038±0.006) of CA3, GL (0.076±0.019) of DG than normal controls (0.068± 0.014, 0.376±0.053, 0.053±0.008,0.056±0.009,0.118±0.026,0.052±0.010,0.053±0.009,0.099±0.015; P< 0.01 or < 0.05). Serum T3 and T4 levels [(1.43±0.30), (157.18±19.95)nmol/L]of hyperthyroid rats were significantly higher than those of control group(P < 0.01). The value was reduced in PCL(0.322±0.050), SR(0.039±0.006), SLM (0.042±0.006) of CA1, PCL(0.098±0.034), SR(0.046±0.013), SLM(0.046±0.010) of CA3 and GL(0.085± 0.024), ML (0.042±0.009) of DG (P < 0.05 or < 0.01). Conclusion Adult-onset of hypothyroidism and hyperthyroidism can reversibly decrease the expression of Syt Ⅰ in CA1, CA3 and DG regions of hippocampus.
