目的探讨右美托咪定(DEX)在0.1%甲醛诱导的急性炎性痛中的作用。方法将30只ICR雌性小鼠随机分成生理盐水对照(NS)组、甲醛(F)组、右美托咪定+甲醛(DEX+F)组。向右后爪足底注射25μl 0.4%甲醛建立小鼠急性炎性痛模型,在甲醛注射前1 h,DEX+F组小鼠腹腔注射DEX,NS组和F组小鼠腹腔注射等体积生理盐水。以小鼠舔咬足累计时间评价自发痛行为。采用免疫组织化学法和Western blotting检测脊髓星形胶质细胞标记物胶质纤维酸性蛋白(GFAP)的表达。结果自发痛评分结果显示,与NS组相比,F组小鼠出现典型的双相痛反应;与F组相比,DEX+F组小鼠的第Ⅰ时相痛(P<0.001)和第Ⅱ时相痛(P<0.001)累计时间明显减少。免疫组织化学结果显示,与NS组相比,F组小鼠脊髓后角GFAP阳性细胞数目明显增多(P<0.001);与F组相比,DEX+F组小鼠脊髓后角GFAP阳性细胞数目明显减少(P<0.001)。Western blotting结果显示,与NS组相比,F组小鼠脊髓GFAP表达明显增加(P<0.05);与F组相比,DEX+F组小鼠...     

雌激素促大鼠急性心肌梗死后心肌血管生成及受体介导机制

目的探讨雌激素对去卵巢大鼠心肌梗死后心脏雌激素受体表达及血管生成的影响。方法结扎去卵巢Sprague-Dauley(SD)大鼠左冠状动脉制作急性心肌梗死模型,给予不同剂量苯甲酸雌二醇干预治疗。放免法测定心肌梗死前和心肌梗死后4周血清雌二醇水平,免疫组化法测定心肌梗死4周后心肌组织中新生毛细血管的数量,Western blot测定心肌组织中细胞核蛋白雌激素受体α、β的表达。结果去卵巢后大鼠血清雌二醇水平显著降低,不同剂量雌二醇干预后各组血清雌二醇水平升高。去卵巢心肌梗死组新生血管数目显著低于保留卵巢急性心肌梗死组及去卵巢后雌激素干预各组,其中,雌激素替代组新生血管数目最高。各实验组雌激素受体α、β蛋白表达均有差异,雌激素替代组表达最高,去卵巢组表达最低。结论体内雌激素同心肌梗死后血管再生有关,雌激素替代治疗有助于增加去卵巢大鼠心肌梗死模型的心肌血管生成,其机制可能是调节心脏雌激素受体α、β介导来发挥作用。

Application of acupuncture in the emergency department for patients with ileus: A pilot prospective cohort clinical study

Acupuncture can be conveniently used for pain control in patients with a variety of conditions, and it has obvious effects on various acute pains. In 2018, we implemented a program for emergency treatment with Chinese medicine to promote the integration of Chinese and Western medicine at the Emergency Department (ED). Ileus is a common cause of abdominal pain among patients in the ED, and it is an indication for emergency treatment with Chinese medicine. This study investigated the efficacy of acupuncture as a traditional Chinese medicine (TCM)-based treatment method for the treatment of patients with ileus in the ED. We analyzed data of patients with ileus, who visited ED between January and December 2019, and compared the length of ED stay between the Western medicine group and the Western medicine plus acupuncture group. Furthermore, pain intensity was measured by a visual analogue scale before and after acupuncture. We found that the length of ED stay was 10.8 hours lesser in the Western medicine plus acupuncture group than in the Western medicine group (P = .04), and the visual analogue scale score decreased by 2.0 on average from before to after acupuncture treatment (P = .02). Acupuncture treatment was effective and rapid in relieving the symptoms and discomfort in patients with ileus and in reducing their length of stay in the ED.     

Early Life Low-Calorie Sweetener Consumption Impacts Energy Balance during Adulthood

Children frequently consume beverages that are either sweetened with sugars (sugar-sweetened beverages; SSB) or low-calorie sweeteners (LCS). Here, we evaluated the effects of habitual early life consumption of either SSB or LCS on energy balance later during adulthood. Male and female rats were provided with chow, water, and a solution containing either SSB (sucrose), LCS (acesulfame potassium (ACE-K) or stevia), or control (no solution) during the juvenile and adolescent periods (postnatal days 26–70). SSB or LCS consumption was voluntary and restricted within the recommended federal daily limits. When subsequently maintained on a cafeteria-style junk food diet (CAF; various high-fat, high-sugar foods) during adulthood, ACE-K-exposed rats demonstrated reduced caloric consumption vs. the controls, which contributed to lower body weights in female, but not male, ACE-K rats. These discrepant intakes and body weight effects in male ACE-K rats are likely to be based on reduced gene expression of thermogenic indicators (UCP1, BMP8B) in brown adipose tissue. Female stevia-exposed rats did not differ from the controls in terms of caloric intake or body weight, yet they consumed more SSB during CAF exposure in adulthood. None of the SSB-exposed rats, neither male nor female, differed from the controls in terms of total adult caloric consumption or body weight measures. The collective results reveal that early life LCS consumption alters sugar preference, body weight, and gene expression for markers of thermogenesis during adulthood, with both sex- and sweetener-dependent effects.
