To explore the mechanism of Modified Qingre Shenshi Decoction（清热渗湿汤化裁）regulating TLR4/NF-κB signaling pathway in improving ulcerative colitis.

A total of150 patients with ulcerative colitis admitted to the hospital from January 2021 to January 2024 were selected and divided into control group（75 cases，treated with mesalazine enteric-coated tablets）and observation group（75 cases，treated with Modified Qingre Shenshi Decoction）according to a random number table.The efficacy and adverse reactions of the two groupswere compared.TCM syndrome scores，disease evaluation，serum factor and mRNA expressions of TLR4 and NF-κB in two groups were observed.

After treatment，the total effective rate of the observation group was higher than that of the control group（P<0.05）.Before treatment，the scores of lower abdomen fullness and pain，burning anus，strong anal distension，diarrhea，mucus，pus and blood stool，heavy limbs，chest tightness and fever，dry mouth and bitter mouth and short urine red were not significant between the two groups（P>0.05）.After treatment，the scores of the above symptoms were all lower than those before treatment.In addition，the scores in the observation group were significantly lower than those in the control group（P<0.05）.Before treatment，the scores of Baron endoscopy and mucosal histology were not significant between the two groups（P>0.05）.After treatment，the scores of Baron endoscopy and mucosal histology in the two groups were lower and the scores in the observation group were significantly lower than those in the control group（P<0.05）.Before treatment，the levels of interleukin-1β，tumor necrosis factor-α，endotoxin and D-lactic acid were not significant between the two groups（P>0.05）.After treatment，the levels of interleukin-1β，tumor necrosis factor-α，endotoxin and D-lactic acid in both groups were lower than those before treatment，and the levels in the observation group were significantly lower than those in the control group（P<0.05）.Before treatment，the mRNA expressions of TLR4 and NF-κB not significant between the two groups（P>0.05）.After treatment，the mRNA expressions of TLR4 and NF-κB in the two groups were lower than those before treatment，and the expressions in the observation group were significantly lower than those in the control group（P<0.05）.There were no adverse reactions in both groups during the treatment.

By regulating TLR4/NF-κB signaling pathway，Modified Qingre Shenshi Decoction can improve the clinical symptoms of patients with ulcerative colitis，plays an anti-inflammatory role and promotes the recovery of patients，which is worthy of clinical application.

To investigate the effects of preparation and processing methods on the contents of oil components in Dihuang（Rehmanniae Radix）and clarify the correlation between oil components with medicinal properties，in order to provide guidance for processing research and clinical application.

The extraction of volatile oil refers to the volatile oil determination method A in the 2020 edition of Chinese Pharmacopoeia，and the Soxhlet method was used to extract fatty oil.Gas Chromatography Mass Spectrometry（GC-MS）was used to identify the oil components and their relative contents.Thermographic analysis was used to clarify the characteristics of the influence of different preparation and processing methods on oil components.Combined with literature review，the correlation of processing，preparation，components and properties was discussed.

The oil components weremainly fatty acids.The order of the extraction rate of fatty oil was fresh Dihuang（Rehmanniae Radix）>raw Dihuang（Rehmanniae Radix）>steaming with wine≈stewing with wine>steaming and exposing nine times with Sharen（Amomi Fructus）>steaming without ingredients，and the order of the volatile oil extraction rate was stewing with wine>steaming with wine>steaming and exposing nine times with Sharen（Amomi Fructus）>raw Dihuang（Rehmanniae Radix）≈steaming without ingredients>fresh Dihuang（Rehmanniae Radix）.The heatmap analysis of fatty oil and volatile oil showed that Shudihuang（Rehmanniae Radix Praeparata）stewing with wine and that steaming and exposing nine times with Sharen（Amomi Fructus）were clustered one category.

The changes and adjustments of the types and relative contents of oil componentswere important material basis for the differences in medicinal property of Dihuang（Rehmanniae Radix）processed products.Adding wine，Sharen（Amomi Fructus）or increasing steaming and exposing times were helpful in reducing the cold nature of Dihuang（Rehmanniae Radix），and the greasy nature of Shudihuang（Rehmanniae Radix Praeparata），and enhance thewarming-reinforcing effect.The volatile oil components in different products of Dihuang（Rehmanniae Radix）were the material basis of their“Qiwei”.

To study the clinical study of Jingu Tongxiao Pill（筋骨痛消丸）combined with arthroscopy in the treatment of knee osteoarthritis（cold coagulation blood stasis syndrome）.
