Ulcerative colitis is a chronic relapsing inflammatory bowel disease. Modern research indicates that immune dysregulation resulting from disruptions in circadian rhythm is closely associated with its pathogenesis. Both Western chronomedicine and traditional Chinese medicine（TCM）" treatment based on temporal factors" emphasize the temporal relationship between natural rhythms and human physiology and pathology. The " midnight-noon and ebb-flow " theory represents the concrete application and deepening of TCM " treatment based on temporal factors" within the realm of chronomedicine. This article correlates the onset time of ulcerative colitis with specific periods in the " midnight-noon and ebb-flow"theory：the Mao period（05：00-07：00），when the yangming large intestine meridian of hand is dominant； the Si period（09：00-11：00），when the taiyin spleen meridian of foot is dominant； and the You period（17：00-19：00），when the shaoyin kidney meridian of foot is dominant. According to this perspective，if the disease manifests during the Mao period，the pathogenesis is attributed to dampnessheat accumulation and disorder of qi and blood. Treatment should focus on clearing heat，resolving dampness，and harmonizing qi and blood，using modified formulas such as Shaoyao Decoction or Baitouweng Decoction. If it occurs during the Si period，the pathogenesis involves spleen deficiency with dampness obstruction and disharmony of qi and blood. Treatment should focus on strengthening the spleen，eliminating dampness，and restoring qi and blood，using modified formulas such as Huangya Decoction or Shenling Baizhu Powder. If it presents during the You period，the pathogenesis is characterized by fire failing to warm earth，and consumption resulting in qi and blood leakage. Treatment should focus on warming the kidney and spleen，and securing qi and blood，using modified formulas such as Sishen Pill or Tianhun Decoction. In addition to oral administration of Chinese herbal medicine，comprehensive therapies including acupuncture，herbal enemas，and acupoint application can provide novel insights for the clinical diagnosis and treatment of ulcerative colitis.

Objective To observe the therapeutic efficacy of foot fumigation with Wen Jing Tong Luo (warming and unblocking meridians and collaterals) powder plus auricular point sticking with magnetic pearls in treating headache after craniocerebral injury. Method Two hundred patients with craniocerebral injury were randomized into a treatment group and a control group. The control group was given regular intervention, while the treatment group was given foot fumigation with Wen Jing Tong Luo powder plus auricular point sticking with magnetic pearls. The pain intensity, the use of analgesics,and satisfaction degree with the treatment were evaluated in 1-4 d after the craniocerebral injury. Result The pain intensity in the treatment group during 1-4 d after the injury was significantly lower than that in the control group (P< 0.01); the total dosage of analgesics used in the treatment group was significantly smaller than that in the control group (P<0.05); the satisfaction degree in the treatment group during 1-4 d after the injury was significantly higher than that in the control group (P<0.01),and the satisfaction degree in the treatment group on the first day after the injury approached to that in the control group on the 4th day after the injury. Conclusion Foot fumigation with Wen Jing Tong Luo powder plus auricular point sticking with magnetic pearls can significantly improve the headache after craniocerebral injury, reduce the use of analgesics,promote the release of headache, and enhance the satisfaction and comfort degree with the analgesic effect, hence, it’s a simple effective assistant method for headache after craniocerebral injury.
