至阳八阵穴隔附子饼灸治疗糖尿病胃轻瘫临床研究

目的观察至阳八阵穴隔附子饼灸治疗脾胃气虚型糖尿病胃轻瘫的疗效及对胃泌素(GAS)、胃动素(MTL)和血管活性肠肽(VIP)水平的影响。方法86例脾胃气虚型糖尿病胃轻瘫患者随机分为对照组和治疗组,每组43例。治疗组给予至阳八阵穴隔附子饼灸;对照组口服枸橼酸莫沙必利片。治疗12周后观察胃轻瘫主要症状指数量表症状积分改善情况、胃排空率及血清GAS、MTL、VIP水平。结果治疗组治疗后在胃轻瘫主要症状指数量表症状积分及胃排空率方面明显高于对照组,差异均有统计学意义(P<0.05)。治疗组治疗后血清GAS、MTL水平明显高于对照组,血清VIP水平明显低于对照组,差异均有统计学意义(P<0.05)。治疗组总有效率为90.7%,明显高于对照组的72.1%(P<0.05)。结论采用至阳八阵穴隔附子饼灸能快速促进糖尿病胃轻瘫患者胃功能的恢复,改善症状和体征,其作用机制可能与升高患者血清GAS和MTL水平,降低VIP水平有关。     

重灸中脘穴对脾胃虚寒型糖尿病胃轻瘫患者胃肠激素、胃动力学的影响

目的观察重灸中脘穴对脾胃虚寒型2型糖尿病胃轻瘫患者胃肠激素、胃动力学的影响。方法选取符合纳入标准的88例脾胃虚寒型糖尿病胃轻瘫患者,按随机数字表法分为治疗组和对照组,每组44例。对照组采用常规药物治疗,治疗组采用重灸中脘穴治疗。疗程结束后记录并对比分析两组临床疗效、胃肠激素[胃泌素(GAS)、胃动素(MTL)]、胃动力学(胃收缩频率、胃排空时间、胃排空率)、主要临床症状评分等变化。结果治疗组临床疗效明显优于对照组,差异具有统计学意义(P<0.05);两组治疗后GAS、MTL均明显优于治疗前(P<0.05),且治疗组明显优于对照组(P<0.05);两组治疗后胃收缩频率、胃排空时间、胃排空率均明显优于治疗前(P<0.05),且治疗组明显优于对照组(P<0.05);两组治疗后主要临床症状评分均明显优于治疗前(P<0.05),且治疗组明显优于对照组(P<0.05)。结论在常规药物治疗基础上重灸中脘穴治疗脾胃虚寒型2型糖尿病胃轻瘫,可调节胃肠激素,改善胃肠动力,促进胃肠功能恢复。     

Clinical implications of gastric complications on levodopa treatment in Parkinson's disease

Disorders of the gastrointestinal (GI) tract are common and distressing nonmotor symptoms of Parkinson's disease (PD) that can adversely affect levodopa absorption and lead to OFF periods, also known as motor fluctuations. Gastroparesis, which is primarily defined as delayed gastric emptying (DGE), and Helicobacter pylori infection, which is present with increased frequency in PD, are among the most common and important GI disorders reported in PD that may impair oral levodopa absorption and increase OFF time. Symptoms of gastroparesis include nausea, vomiting, postprandial bloating, fullness, early satiety, abdominal pain, and weight loss. DGE has been reported in a substantial fraction of individuals with PD. Symptoms of H. pylori infection include gastritis and peptic ulcers. Studies have found that DGE and H. pylori infection are correlated with delayed peak levodopa plasma levels and increased incidence of motor fluctuations.Therapeutic strategies devised to minimize the potential that gastric complications will impair oral levodopa absorption and efficacy in PD patients include treatments that circumvent the GI tract, such as apomorphine injection, levodopa intestinal gel delivery, levodopa inhalation powder, and deep brain stimulation. Other strategies aim at improving gastric emptying in PD patients, primarily including prokinetic agents.     

胃大部切除术后残胃胃瘫综合征临床分析

目的探讨胃大部切除术后残胃胃瘫综合征(PGS)的病因、诊断及治疗。方法对20例胃大部切除术后发生胃瘫综合征的发病因素、临床表现、诊断方法及治疗手段进行分析。结果术前流出道梗阻和胃肠吻合方式是术后PGS的高危因素。胃镜、X线口服造影对PGS的诊断有价值。经非手术治疗,术后PGS在术后6周内一般可以恢复。结论胃大部切除术后残胃胃瘫综合征在术前流出道梗阻、胃肠毕Ⅱ式吻合的病人中发病率较高,患者经过6周的非手术治疗后,多数可以缓解恢复,从而避免了二次手术的痛苦。     

Rapid improvement in post-infectious gastroparesis symptoms with mirtazapine

We report the case of a 34-year-old woman with severe post-infectious gastroparesis who was transferred from an outside medical facility for a second opinion regarding management.This patient had no prior history of gastrointestinal symptoms.However,in the aftermath of a viral illness,she developed two months of intractable nausea,vomiting,and oral intake intolerance that resulted in numerous hospitalizations for dehydration and electrolyte disturbances.A solid-phase gastric emptying scan had confirmed delayed emptying,confirming gastroparesis.Unfortunately,conventional pro-kinetic agents and numerous anti-emetic drugs provided little or no relief of the patient’s symptoms.At our institution,the patient experienced a cessation of vomiting,reported a significant reduction in nausea,and toler-ated oral intake shortly after taking mirtazapine.Based on mirtazapine’s primary action as a serotonin(5-HT)1a receptor agonist,we infer that this receptor system mediated the clinical improvement through a combination of peripheral and central neural mechanisms.This report highlights the potential utility of 5-HT1a agonists in the management of nausea and vomiting.We conclude that mirtazapine may be effective in treating symptoms associated with non-diabetic gastroparesis that are refractory to conventional therapies.     

经口内镜幽门肌切开术在治疗胃轻瘫中的应用及研究现状

【摘要】胃轻瘫,也称胃无力、胃麻痹,是一种以胃排空延迟为特征的的临床症候群,显著影响患者的生活质量,而有效的治疗方法非常有限。2013年第一例经口内镜幽门肌切开术(G-POEM)的报道,为治疗顽固性胃轻瘫带来了新的思路。其安全性和有效也在随后的病例系列报道中得到证实。作为一种新兴的经自然孔道腔内内镜手术(NOTES)方法,G-POEM越来越多地被研究与关注。现谨对G-POEM方法及在治疗胃轻瘫中的应用及研究现状做一综述。
