中医药防治多器官功能障碍综合征探讨

多器官功能障碍综合征(MODS)是创伤及感染后最严重的并发症。近年来,现代医学对MODS发生机制的认识已有长足进步,相对而言,临床疗效就不那么令人满意了。尽管全力采取积极复苏、器官支持、抗感染、介质拮抗等手段,其病死率仍居高不下。因此,越来越多的有识之士认为,运用中医药防治MODS是今后的一个重要发展方向。1　中医药防治MODS的简要回顾中医药治疗MODS是从治疗单一脏器衰竭起步的。王今达等于1972年用血府逐瘀汤治疗天津首例确诊DIC获成功。1976年根据ARDS多有苔黄燥、脉洪大、腹胀满、大便秘结之阳明腑实证,选凉膈散为主方…     

CCL2-2518λ������̬������֢��������71�͸�Ⱦ������о�

??Objective To investigate the relationship between CCL2-2518A/G gene polymorphism and severity of enterovirus 71??EV71?? infection. Methods CCL2 gene polymorphism in 188 EV71-infected patients and 235 healthy controls were detected by the improved multiplex ligation detection reaction technique??iMLDR??. The level of CCL2 in two groups was determined by enzyme-linked immunosorbent assay??ELISA??. Results No significant differences were found in the distribution of genotype CCL2-2518A/G between EV71-infected patients and the healthy control group??P??0.05??. The G allele??genotypes AG or GG?? in the CCL2-2518A/G??P??0.001?? was more frequent in patients with severe EV71 infection. The level of CCL2 in infected patients was higher than that of the heathy controls ??P??0.05???? the severe cases had higher level of CCL2 than that of the slight cases and healthy controls??P??0.05??. The level of CCL2 in GG gene group was significantly higher than that in AG gene group and the level of CCL2 in AG gene group was significantly higher than that in AA gene group.The people with CCL2-2518G allele??GG+AG?? had higher level of CCL2 than those only with CCL2-2518A allele??AA????P??0.05??. Conclusion The G carrier of the CCL2-2518A/G is found to be associated with severity of EV71 infection??and could be susceptibility factors in the development of EV71 infection.     

Hypertension and diabetes synergistically strengthen the association with cataracts among Chinese

AIM: To examine the relationship between age-related cataracts (ARC) and comorbid hypertension and diabetes. METHODS: We analyzed the administrative records of 6,467 patients aged 50 years and older admitted to the ophthalmological department of a tertiary hospital from January 1st, 2011 to May 20th, 2017. With either eye considered, an ARC (n=3,343) was defined as the presence of lens opacity or previous cataract surgery without evidence of trauma, congenital anomalies or using certain medications. Patients admitted to the same department during the same period due to ocular traumas without clinical evidence of cataracts (n=379) were recruited as the cataract-free controls. Unconditional logistic regressions were obtained the odds ratio (OR) of hypertension and diabetes among ARC patients adjusted for age, sex and health care accessibility. RESULTS: Hypertension was diagnosed in 29.54% of men with any type of cataracts, in 30.12% of men with an ARC, and 10.82% of men of cataract-free controls. Diabetes was diagnosed in 16.64% of men with any type of cataracts, in 16.48% of men with ARC and 4.22% of men of cataract-free controls. Similar patterns were observed among women. After adjusting for age, sex, and health care accessibility, hypertension was weakly [OR=1.83 (95%CI: 1.23, 2.74)] and diabetes was strongly [3.38 (1.86, 6.15)] associated with ARCs. The adjusted OR of comorbid hypertension and diabetes among adults with ARC was 18.20 (4.38, 75.59). CONCLUSION: Hypertension and diabetes were independently associated with ARC. Hypertension and diabetes, if co-existing, multiplicatively strengthened the association with ARC.

孤束核损毁术后艾灸足三里穴对胃黏膜损伤模型大鼠TNF-α、NO和HSP70表达的影响

目的:观察孤束核捣毁术后艾灸"足三里"穴对胃黏膜损伤模型大鼠肿瘤坏死因子α(TNF-α)、血清一氧化氮(NO)与热休克蛋白(HSP70)表达的影响,并分析在艾灸保护胃黏膜损伤的神经通路中孤束核所起的作用。方法:将SD大鼠48只随机分为正常组(A组)、模型组(B组)、艾灸+模型组(C组)、艾灸+模型+孤束核损毁组(D组),每组12只,无水乙醇灌胃造成胃黏膜损伤,并用阿司匹林混悬液连续灌胃3d维持损伤(A组予0.9%氯化钠注射液灌胃),按Guth法计算胃黏膜损伤指数(UI),采用ELISA法检测胃黏膜细胞凋亡相关因子TNF-α、NO含量,并采用Western-blot法检测大鼠胃黏膜组织中保护蛋白HSP70的含量。结果:B组胃黏膜出现明显损伤,表明采用无水乙醇灌胃及阿司匹林悬浊液灌胃法造模成功(P0.05);C、D组UI指数较B组均有不同程度的下降(P0.01,P0.05),D组UI指数较C组高(P0.01)。C、D组胃黏膜组织中TNF-α含量较B组均有不同程度的下降,NO含量均有上升(P0.05,P0.01);D组胃黏膜组织中TNF-α含量较C组高,而NO含量较C组低(P0.01)。胃黏膜保护蛋白HSP70的表达C、D组较B组均有明显上升(P0.01),同时D组的表达较C组低(P0.05)。结论:艾灸足三里穴对胃黏膜损伤有明显的保护性调节作用,而孤束核损毁后其保护效应受到明显抑制,证明对大鼠足三里穴进行温和灸后产生胃黏膜保护机制非常重要的传导中枢是孤束核。

Qiangli Wuhu mixture alleviates LPS-induced pneumonia by inhibiting the TLR4/NF-κB/NLRP3 pathway: a study based on network pharmacology

ContextQiangli Wuhu (QLWH) mixture is a concoction approved and registered by Ningxia Medical Products Administration. It has therapeutic effects on various types of pneumonia.ObjectiveTo clarify the mechanisms of QLWH in treating pneumonia.Materials and methodsThe potential targets of QLWH in the treatment of pneumonia were predicted by network pharmacology. Male, Institute of Cancer Research (ICR) mice were randomly divided into five groups of 12 mice, control, vehicle, QLWH (10 and 20 mg/kg) and dexamethasone (DXM), and orally treated twice daily with normal saline, QLWH or DXM. The pneumonia model was established by tracheal instillation of lipopolysaccharide (LPS). After treatment five days, ELISA, H&E staining and Western blot were used to investigate protective effects of QLWH.ResultsNine hundred and ninety-four active ingredients were found through network pharmacology, corresponding to 135 targets for the treatment of pneumonia; compared to the vehicle group, QLWH (10 and 20 mg/kg) significantly decreased the levels of TNF-α (14.3% and 28.8%), IL-1β (23.9% and 42.8%) and IL-6 (13.2% and 16.1%), increased the levels of IL-10 (134.3% and 172.9%); in terms of mechanism, QLWH down-regulated TLR4/NF-κB/NLRP3 axis related proteins in lung tissue of pneumonia model mice (p < 0.05).Discussion and conclusionsThis study combined network pharmacology and animal experiments, providing effective evidence for the clinical promotion of QLWH. Meanwhile, it is of significance for further development.
