胃脘痛肝郁脾虚证相关穴皮肤微循环流量变化

本研究采用激光多普勒微循环流量计对７３例胃脘痛肝郁脾虚证患者通过相关穴位测定其皮肤微循环流量改变，近取脾、胃经募穴、背俞穴；远取脾、胃经输穴、合穴。结果表明，胃脘痛肝郁脾虚证Ⅰ、Ⅱ型相关各穴皮肤微循环流量值均非常明显低于正常对照组，提示该病证病理机制之一在于微循环流量改变方面。其中，足三里穴具有相对特异性：１．该病证足三里穴流量值明显低于正常对照组；２．脾虚为主的Ⅱ型比肝郁为主的Ⅰ型该穴流量值明显减低；３．Ⅱ型组内各穴流量值以该穴为最低。可见该穴在微循环流量改变方面最为敏感，并为针灸治疗该病证优选穴位提供客观依据。

Effect of Soothing Gan (Liver) and Invigorating Pi (Spleen) Recipes on TLR4-p38 MAPK Pathway in Kupffer Cells of Non-alcoholic Steatohepatitis Rats

Objective: To investigate the mechanism of inflammatory-mediated toll-like receptor 4(TLR4)-p38 mitogen-activated protein kinase(p38 MAPK) pathway in Kupffer cells(KCs) of non-alcoholic steatohepatitis(NASH) rats and the intervention effect of soothing Gan(Liver) and invigorating Pi(Spleen) recipes on this pathway. Methods: After 1 week of acclimatization, 120 Sprague-Dawley male rats were randomly divided into 8 groups using a random number table(n=15 per group): normal group, model group, low-dose Chaihu Shugan Powder(柴胡疏肝散, CHSG) group(3.2 g/kg), high-dose CHSG group(9.6 g/kg), low-dose Shenling Baizhu Powder(参苓白术散, SLBZ) group(10 g/kg), high-dose SLBZ(30 g/kg) group, and low-and highdose integrated recipe(L-IR, H-IR) groups. All rats in the model and treatment groups were fed with a high-fat diet(HFD). The treatments were administrated by gastrogavage once daily and lasted for 26 weeks. The liver tissues were detected with hematoxylin-eosin(HE) and oil red O staining. Levels of liver lipids, serum lipids and transaminases were measured. KCs were isolated from the livers of rats to evaluate the mRNA expressions of TLR4 and p38 MAPK by real-time fluorescence quantitative polymerase chain reaction, and proteins expressions of TLR4, p-p38 MAPK and p38 MAPK by Western blot. Levels of inflammatory cytokines including tumor necrosis factor α(TNF-α), interleukin(IL)-1 and IL-6 in KCs were measured by enzyme-linked immunosorbent assay. Results: After 26 weeks of HFD feeding, HE and oil red O staining showed that the NASH model rats successfully reproduced typical pathogenesis and histopathological features. Compared with the normal group, the model group exhibited significant increases in body weight, liver weight, liver index, serum levels of total cholesterol(TC), triglyceride(TG), low-density lipoprotein cholesterol, and aspartate aminotransferase as well as TC and TG levels in liver tissues, and significant decrease in serum level of high-density lipoprotein cholesterol(P0.05 or P0.01), while those indices were significantly ameliorated in the H-IR group(P0.05 or P0.01). Higher levels of TNF-α, IL-1 and IL-6 in KCs were observed in the model group compared with the normal group(P0.01). Significant decreases in TNF-α, IL-1 and IL-6 were observed in the H-SLBZ, H-IR and L-IR groups compared with the model group(P0.05 or P0.01). The m RNA expressions of TLR4 and p38 MAPK and protein expressions of TLR4, p38 MAPK and p-p38 MAPK in KCs in the model group were significantly higher than the normal group(P0.01), while those expression levels in the L-IR and H-IR groups were significantly lower than the model group(P0.05 or P0.01). Conclusions: Inflammation in KCs might play an important role in the pathogenesis of NASH in rats. The data demonstrated the importance of TLR4-p38 MAPK signaling pathway in KCs for the anti-inflammatory effect of soothing Gan and invigorating Pi recipes.     

在医院中建立舒心服务模式的思考

“生物-心理-什会”新医学模式的提出已经20多年，但探索与之相通啦的医学提供方式或医学服务模式的成效仍然不显著。作者以新医学模式理论、马斯洛需求层次理论、医学社会学等理论作为指导，提出要践行新的医学模式就需要在医院中建立舒心服运务模式，在对病人身体疾患高品质诊治的同时，医疗服务要以病人的感知、体验是否舒心作为出发点或落脚点，注重病人心理及社会缺失的全面诊断或评估，并完整提供病人及其亲友参与、可定制、个性化、贴切的身心诊疗及人文化的服务方案。同时提出了建立舒心服务模式有待研究的问题。
