红外热成像对蚕沙外熨辅助治疗糖尿病胃轻瘫的疗效评价研究

Efficacy evaluation of infrared thermal imaging assisted by hot compressing with silkworm excrement in the treatment of diabetic gastroparesis

目的研究采用蚕沙外熨腹部的方法辅助治疗糖尿病胃轻瘫的有效性,探讨治疗过程中红外热成像对临床疗效评价的作用。方法将110例糖尿病胃轻瘫患者随机分为治疗组55例、对照组55例。其中治疗组脱落3例,完成病例观察52例,脱落率为5.45%;对照组脱落5例,完成病例观察50例,脱落率为9.09%。2组均予基础治疗,治疗组在基础治疗上辅以蚕沙外熨治疗,对照组在基础治疗上辅以热水袋外熨。在入组时、2周及4周随访时进行红外热成像检测及彩超胃排空率检测。比较2组胃脘部、中脘穴、大腹部、左右足三里绝对温度、相对温度以及彩超胃排空率。结果 2组彩超胃排空率在治疗2周时及随访时,与治疗前比较差异均有统计学意义(P<0.05);重复测量方差分析结果显示:T_(3),△T_(1),△T_(4)在组别和观察时间的交互作用有统计学意义(P<0.05)。2组组间比较显示:治疗组△T_(3)较对照组下降,差异有统计学意义(F_(组间)=6.48,P<0.05)。结论蚕沙外熨法辅助治疗能够改善糖尿病胃轻瘫患者彩超胃排空率,降低红外热成像检测时大腹部的相对温度。红外热成像检测能够评估糖尿病胃轻瘫的临床疗效。

Objective To observe the efficacy of the treatment of diabetic gastroparesis(DGP) assisted by hot compressing with silkworm excrement and to investigate the role of infrared thermal imaging in its efficacy evaluation. Methods One hundred and two patients with DGP were assigned to the control group(n=55) and treatment group(n=55). In the treatment group, 3 cases were abscessed, and 52 cases were observed with an abscission rate of 5.45%.In the control group, 5 cases were abscessed and 50 cases were observed with an abscission rate of 9.09%.Both groups received Western conventional treatment of diabetes. The treatment group received hot compressing with silkworm excrement, while the control group received hot compressing with a hot water bag. Both groups were examined by gastric emptying rate testing, infrared thermal imaging when they participated in the project at 2 weeks and 4 weeks. The absolute temperature(T) and relative temperature(ΔT) of the stomach cavity region, Zhongwan acupoint, abdominal region, the left and right Zusanli acupoints of the 102 patients were measured. The differences in T, ΔT and gastric emptying rate of the two groups were compared. Results Compared with before treatment, the gastric emptying rate was significantly improved after treatment and during follow-up(P<0.05).Repeated measurement analysis of variance showed that: As for the T_(3),△T_(1),△T_(4), the interaction between groups and observation time was statistically significant(P<0.05).Compared with the control group, △T_(3) was lower in the treatment group than in the control group, and the difference was statistically significant(P<0.05).Conclusions The treatment of DGP by hot compressing with silkworm excrement can improve the gastric emptying rate of patients with DGP. Meanwhile, the relative temperature of abdomen region appears to increase in the infrared thermal imaging. Infrared thermal imaging can assess the clinical efficacy of DGP.
