Astaxanthin for Dyspepsia and Helicobacter pyloriDyspepsia is the general term given to a variety of digestive problems localized in the upper abdominal region. Typical symptoms for example include stomach pain, gas, acid-reflux or bloating. Dyspepsia is like the stomach version of the irritable bowel syndrome and its symptoms may appear at any age or to any gender. The medical approach to dyspepsia involves looking for treatable causes and addressing them if identified. Failing that, doctors suggest treatments by trial-and-error. The problem associated with this non-standardized approach involves drugs that may not work, may cause side effects and exacerbate the patient’s condition brought on by stressful attempts to cure symptoms. To understand the benefits of astaxanthin in dyspepsia, it is necessary to categorize specific types; most common forms are either non-ulcer dyspepsia or gastric dyspepsia. Non-ulcer dyspepsia problems usually do not have an identifiable cause, but fortunately, for most cases it is non-disease related and therefore temporary. On the other hand, gastric type dyspepsia is more severe and linked to identifiable causes. For example, the bacterial infection of Helicobacter pylori is a commonly known cause. Pathological symptoms of H.pylori infection include high levels of oxidative stress and inflammation in the stomach lining and symptoms like gastric pain and acid reflux., H.pylori can contribute to mild and severe kinds of symptoms, but on the other hand, people who are H.pylori positive can remain asymptomatic whereas others may develop into clinical problems. It is still unclear what triggers the severe form of infection and how the bacteria is passed on, but scientists suggested using strong antioxidants like astaxanthin for therapy and better long term protection. in mice lowered inflammation after 10-days of treatment (in vivo), and also inhibit H. pylori growth (in vitro). The mice treated with astaxanthin (10 mg/kg body weight) had the same effect as vitamin C (400 mg/Kg) which significantly lowered gastric inflammation and lipid peroxidation (Figure 4) compared to infected control mice; which continued to develop severe gastritis.

【摘 要】目的：探讨检测血清降钙素原（procalcitonin，PCT）、C-反应蛋白（C-reactive protein，CRP）水平对指导细菌感染引起慢性阻塞性肺疾病急性加重期（acute exacerbation of chronic obstructive pulmonary disease，AECOPD）患者临床诊治中的意义。方法对AECOPD患者58例(A组)及COPD稳定期患者31例（B组），采用免疫发光法测定其血清PCT及CRP水平,并进行诱导痰细菌定量培养；以痰中下呼吸道潜在病原菌(PPM)浓度107CFU/mL作为诊断AECOPD细菌感染的标准，将AECOPD患者分为有细菌感染组(A1组35例)、无细菌感染组(A2组23例)。结果 AECOPD有细菌感染组血清PCT（0.22±0.03）ng/mL，CRP（59.79±10.23）mg/mL水平高于无细菌感染组PCT（0.11±0.02）ng/mL，CRP（18.34±3.15）mg/mL及稳定期组PCT（0.08±0.01）ng/mL，CRP（10.06±1.63）mg/mL，差异有统计学意义(P<0.05)。COPD急性加重期无细菌感染组PCT（0.11±0.02）ng/mL水平高于稳定期组PCT（0.08±0.01）ng/mL，差异无统计学意义(P>0.05)，急性加重期无细菌感染组CRP（18.34±3.15）mg/mL水平高于CRP（10.06±1.63）mg/mL，差异有统计学意义(P<0.05)。结论 COPD患者PCT水平升高可能与细菌感染有关、而CRP水平升高可能提示急性加重，联合检测血清PCT及CRP可以帮助了解AECOPD的细菌感染及指导抗生素应用。%Objective To evaluate the clinical significance of concurrent determination of serum procalcitonin (PCT) and C-reactive

降钙素原与C反应蛋白联合检测的临床意义

摘要：目的 探讨降钙素原（PCT）与C反应蛋白（CRP）联合检测在局部细菌感染和脓毒血症诊断中的临床应用价值。方法 分别对来自医院重症监护室的40例脓毒血症患者和来自医院住院病房的50例局部细菌感患者进行降钙素原和C-反应蛋白检测；同时收集20例体检中心健康人群标本作为对照组进行检测。结果

40例全身细菌性感染患者降钙素原和C反应蛋白检测结果均显著高于20例健康对照组标本检测结果差异显著（P<0.01），有统计学意义。50例局细菌感染患者降钙素原检测结果与健康对照组降钙素原检测结果相比无显著差异（P>0.05），无统计学意义；50例局部细菌感染患者C反应蛋白检测结果显著高于健康对照组C反应蛋白检测结果（P<0.01），差异显著，有统计学意义。结论 降钙素原与C反应蛋白联合检测有助于临床医师诊断患者是否存在局部细菌感染或全身性细菌感染，为临床合理使用抗生素提供依据。
