    • 摘要: 目的:探讨黄连解毒汤对脑梗死合并胃损伤大鼠干细胞因子/酪氨酸激酶受体(SCF/C-kit)信号通路的影响。方法:将80只健康10周龄雄性Wistar大鼠随机分为模型组、黄连解毒汤组、奥美拉唑组、假手术组、正常组,以上各组再分设4 d组、7 d组,共10组。采用线栓法建立大脑中动脉梗死模型。黄连解毒汤组给予黄连解毒汤(27 mg/ml)混悬液,奥美拉唑组给予奥美拉唑(15 mg/ml)悬浊液,其余组给予1 ml 0.9%氯化钠溶液灌胃,4 d组连续灌胃4 d,7 d组连续灌胃7 d。采用HE染色法观察大鼠胃组织病理形态学变化,并进行病理损伤评分;采用实时荧光定量检测大鼠胃组织SCF、C-kit mRNA表达水平;采用Western blot检测大鼠胃组织中SCF、C-kit蛋白表达水平。结果:与正常组、假手术组比较,模型组、黄连解毒汤组、奥美拉唑组大鼠胃黏膜病理评分均明显升高(4、7 d组均P0.05)。与模型组比较,黄连解毒汤组、奥美拉唑组大鼠胃黏膜病理评分均显著降低(4、7 d组均P<0.01),胃组织SCF、C-kit mRNA和蛋白表达水平均明显升高(P<0.01)。与奥美拉唑组比较,黄连解毒汤组大鼠胃黏膜病理评分均明显降低(P<0.05),胃组织SCF、C-kit mRNA和蛋白表达水平均明显升高(P<0.05)。结论:黄连解毒汤对脑梗死合并胃损伤大鼠的胃黏膜具有一定的保护作用,其机制可能与黄连解毒汤升高大鼠胃组织SCF、C-kit mRNA及蛋白的表达水平有关。
    • 摘要: 1.忌酗酒无度。酒精本身可直接损害胃黏膜,加重胃的损伤,还可能引起肝硬化和慢性胰腺炎。2.忌嗜烟成癖。吸烟会刺激胃酸和蛋白酶的分泌,加重对胃黏膜的破坏。3.忌饥饱不均。饥饿时,胃酸、蛋白酶浓度较高,易造成胃黏膜的自我消化。而暴饮暴食也易损害胃肠自我保护机制,食物停留时间过长会造成胃损伤

    • 摘要: cqvip:胸腔置管引流术是结核性胸膜炎伴胸腔积液患者常用的治疗方法,患者容易接受,能减少反复胸腔穿刺给患者带来的痛苦及风险,还可以随时进行胸腔给药。一般胸腔置管引流术根据患者体位给予B超下定位,常见部位为腋后线第7~9肋间,因胸腔置管引流术误入胃腔的发生率极低,文献报道不多见^([1-2]),现报道1例胸腔置管引流误入胃腔病例。

    • 摘要: 本文对不同年份生普洱茶多酚的体外抗氧化效果及其对小鼠酒精性胃损伤的保护作用进行了研究.分别从2008年、2012年和2016年生普洱茶中提取总多酚物质,采用福林-酚法测定总多酚含量,分别测定3个年份生普洱茶多酚体外清除2,2'-联氨-双-3-乙基苯并噻唑啉-6-磺酸(2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid),ABTS)自由基、1,1-二苯基-2-三硝基苯肼(1,1-diphenyl-2-picrylhydrazyl,DPPH)、羟基自由基的能力以及测定其还原力.将50只清洁级昆明小鼠随机分为正常组、模型组、2008年组(200 mg/(kg· BW))、2012年组(200 mg/(kg·BW))和2016年组(200 mg/(kg· BW)),每组10只.采用60%乙醇溶液诱导小鼠急性胃损伤模型,测定小鼠胃液量和胃酸值,H&E染色观察小鼠胃黏膜的组织形态改变,测定小鼠血清谷胱甘肽(glutathione,GSH)含量、丙二醛(malondialdehyde, MDA)含量及超氧化物歧化酶(superoxide dismutase,SOD)活力,采用RT-qPCR测定小鼠胃组织中内皮型一氧化氮合酶(endothelial nitric oxide synthase,eNOS)、神经元型一氧化氮合酶(neuronal nitric oxide synthase,nNOS)和环氧合酶2(cyclooxygenase-2,COX-2)的mRNA表达水平.结果 表明,3个年份生普洱茶多酚对ABTS+自由基、DPPH自由基和羟基自由基清除能力均高于Vc阳性对照,同时还具有较强的还原力,综合比较抗氧化能力大小为:2016年生普洱茶多酚>2012年生普洱茶多酚>2008年生普洱茶多酚;3个年份的生普洱茶多酚均能明显改善胃黏膜损伤,减少胃液量分泌,维持正常胃酸值;3个年份生普洱茶多酚均可显著增加小鼠血清中SOD酶活力,增加GSH含量,降低MDA含量(p<0.05),还能显著增加小鼠胃组织中eNOS、nNOS的mRNA表达,降低COX-2的mRNA表达(p<0.05).综上,生普洱茶多酚对小鼠酒精性胃损伤具有一定的抑制作用,这可能与其抗氧化效果、抗炎及增强胃黏膜保护因子等作用有关.

mechanism of hydrogen-rich water (HRW) on ethanol-induced acute gastric injury.Methods The experimental study was conducted.Forty kunming mice were divided into the 4 groups by random number table method:normal control group [0.01 mL/g normal saline (NS)+ 0.03 mL/g NS],HRW group (0.01 mL/g NS +0.03 mL/g HRW),ethanol model group (0.01 mL/g 56°alcoholic drinks +0.03 mL/g NS),HRW treated group (0.01 mL/g 56°alcoholic drinks +0.03 mL/g HRW).Ten mice in each group were administrated twice a day for 7 days.Testing indicators:(1) gastric ulcer index was measured,(2) pathological examination of gastric tissues,(3) activity of serum superoxide dismutase (SOD) and expressions of malondialdehyde (MDA),interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α) were measured,(4) expressions of SOD and MDA in gastric tissues were measured,(5) protein expressions of apoptosis related factors (caspase-3,bax,caspase-9,fas and caspase-8) in gastric tissues were measured by immunohistochemistry,(6) relative expressions of mRNA of apoptosis related factors (caspase-3,bax,caspase-9,fas and caspase-8) in gastric tissues were measured by realtime polymerase chain reaction (RT-PCR).Measurement data with normal distriburion were presented as (x)±s.Comparisons among groups were done using the one-way ANOVA and comparison between groups was done using the LSD-t test.Results (1) Gastric ulcer index was measured:gastric ulcer index of mice in the normal control group,HRW group,ethanol model group and HRW treated group were respectively 0,0,10.40± 1.64 and 3.92 ± 0.23,with statistically significant differences (F=175.050,P<0.05).There was a statistically significant difference between the ethanol model group and normal control group or HRW treated group (t =19.835,12.352,P< 0.05).(2) Pathological examination pathological examination of gastric tissues:① Macropathology of gastric tissues:the surface of the gastric mucosa was normal and smooth in the normal control group and the HRW group,without ulcer,erosion and inflammation.The partial gastric mucosal erosion and ulcer in the ethanol model group was large and very severe.Compared with the ethanol model group,the area of gastric mucosal lesion was reduced in the HRW treated group.② Results of pathological examination of gastric tissues:gastric mucosa in the normal control group and HRW group were integrity.Compared with the normal control group,the partial gastric surface epithelium was degenerate and impaired in the ethanol model group.Compared with the ethanol model group,the gastric mucosal erosion and inflammatory cell infiltration were alleviated in the HRW treated group.(3) Expressions of serum SOD,MDA,IL-6 and TNF-α:expressions of serum SOD,MDA,SOD/MDA and IL-6 were respectively (70±6)U/mL,(7.52±0.23) μmol/L,9.40 ± 1.07,(6.3 ± 1.8) ng/L in the normal control group and (74 ± 4) U/mL,(7.61 ±0.91) μmol/L,9.91 ± 1.55,(5.1 ± 1.6)ng/ L in the HRW group and (101 ± 4) U/mL,(16.95 ±

the 4 groups (F=97.405,269.950,16.486,25.663,P<0.05).The serum TNF-α levels were respectively (53± 14) ng/L,(67± 17) ng/L,(52± 13) ng/L,(58±21) ng/L in the above 4 groups,with no significant difference (F=0.862,P>0.05).(4) Expressions of SOD and MDA in gastric tissues were measured:expressions of SOD and MDA and SOD/MDA were respectively (93 ± 18) U/mL,(7.90± 1.72) μmol/L,12.48±4.54 in

tissues:the results of immunohistochemistry showed that the levels of caspase-3,bax and fas were repectively 0.065 5± 0.003 7,0.065 7±0.003 0,0.225 4±0.024 3 in the normal control group and 0.065 7±0.002 7,0.064 9±0.003 0,0.246 0±0.022 3 in the HRW group and 0.330 7±0.017 3,0.335 4±0.033 3,0.397 0±0.028 5 in the ethanol model group and 0.096 7±0.003 0,0.084 8±0.001 7,0.375 0±0.035 6 in the HRW treated group,showing statistically significant differences among the 4 groups (F=1 004.222,309.171,48.555,P<0.05).The levels of caspase-9 and caspase-8 were respectively 0.049 2±0.000 4,0.151 5±0.010 2 in the normal control group and 0.047 9±0.002 0,0.154 00.013 5 in the HRW group and 0.047 0±0.003 7,0.157 2±0.006 2 in the ethanol model group and 0.048 7±0.000 8,0.153 9±0.006 3 in the HRW treated group,with no statistically significant difference among the 4 groups (F=0.998,0.297,P>0.05).(6) The mRNA expressions of apoptosis related factors in gastric tissues:resutls of RT-PCR showed that relative expressions of mRNA of caspase-3,bax,caspase-9 and fas were respectively 1.00±0.00,1.00±0.00,1.00±0.00,1.00±0.00 in the normal control group and 0.72±0.43,0.66±0.26,1.57±0.31,0.50±0.19 in the HRW group and 3.19±0.87,1.58±0.76,3.04± 1.15,2.84±0.98 in the ethanol model group and 0.49±0.16,0.69±0.25,2.98±0.85,0.53±0.24 in the HRW treated group,showing statistically significant differences among the 4 groups (F=32.106,5.038,9.706,23.387,P<0.05).The mRNA levels of caspase-8 were respectively 1.00±0.00,1.50±0.60,1.36±0.34,1.32±0.43 in normal control group,HRW group,ethanol model group and HRW treated group,with no significant difference among the 4 groups (F=1.337,P>0.05).Conclusions Hydrogen-rich water could alleviate ethanolinduced acute gastric injury by antioxidant,anti-inflammatory and anti-apoptosis.Hydrogen-rich water is safe and reliable,without toxic and side effects on the body.
