This study was aimed to analyze the composition principles of prescriptions for sequela of apoplexy collected in the CNKI by the Traditional Chinese Medicine Inheritance Platform (TCMIP), in order to provide a reference for clinical selection of medication. Prescriptions for the sequela of apoplexy treatment in CNKI were collected. Based on the TCMIP, the medication rules of prescription were analyzed by data mining method after data entry. A total of 190 prescriptions involving 204 herbs for sequela of apoplexy treatment were screened and studied. The herbs for blood-activating andqi-tonifying were used with higher frequency. There were 36 commonly used herbal pairs. The herb pair of Dang-Gui(Radix Angelicae Sinensis) andHuang-Qi (Radix Astragali) was with the highest frequency. The herbal combination with three types of herbs wasDi-Long (Pheretima),Dang-Gui andHuang-Qi. The herbal combination with four types of herbs wasChuan-Xiong (Rhizoma Chuanxiong),Di-Long,Dang-Gui andHuang-Qi. The analysis on association rule showed thatChuan-Xiong,Dang-Gui,Tao-Ren (Semen Persicae),Hong-Hua(Flos carthami) andHuang-Qiwere often combined with each other. A total of 48 core combinations and 11 new prescriptions were mined. It was concluded that the prescriptions for sequela of apoplexy were mainly composed with herbs for blood-activating,qi-tonifying and collateral-dredging. According to the flavor and meridian tropism theory of Chinese medicine, the herbal medication selection in the prescription was mostly warm and hot in nature, sweet and pungent flavor, and the meridian tropism of the liver and spleen meridian.

Objective To evaluate effects of artesunate on rosacea-like inflammation in mouse models.Methods Twenty-five male BALB/c mice aged 7 weeks were injected subcutaneously with 40 μ1 antibacterial peptide LL-37 into the back once every 12 hours for 4 sessions to establish mouse models with rosacea-like inflammation.These 25 mice were randomly and equally divided into 5 groups:after each injection of LL-37,model group were gavaged with sodium chloride physiological solution,treatment groups gavaged with 25,50 and 100 mg/kg artesunate solution separately,and positive control group gavaged with 30 mg/kg doxycycline hydrochloride solution.Another 5 healthy mice injected subcutaneously with pure water into the back for 4 sessions served as blank control group.Forty-eight hours after the initial injection of LL-37,changes in skin lesions and the intensity of erythema were assessed.Skin tissues at the dorsal injection site were resected and subjected to HE staining,the tissue structure was observed and the number of inflammatory cells was counted.Enzyme-linked immunosorbent assay (ELISA) was performed to estimate the activity of myeloperoxidase (MPO) in skin lesions.Results The model group showed obvious inflammatory reactions,and significantly increased erythema score (3.20 ± 0.84),inflammatory cell count (517.27 ± 99.43) and MPO activity (0.57 ± 0.08) compared with the blank control group (all P ＜ 0.01).The positive control group showed significantly decreased erythema score (1.60 ± 0.89),inflammatory cell count (270.93 ± 124.63) and MPO activity (0.40 ± 0.05) compared with the model group (P ＜ 0.05,0.01,0.01,respectively).Moreover,the erythema score,inflammatory cell counts and MPO activity were all significantly lower in 50-(1.80 ± 0.84,286.00 ± 33.72,0.43 ± 0.05,respectively) and 100-mg/kg artesunate groups (1.40 ± 0.55,258.00 ± 36.44,0.40 ± 0.06,respectively) than in the model group (P ＜ 0.05 or 0.01).However,there were no significant differences in the erythema score,inflammatory cell count and MPO activity between 50-or 100-mg/kg artesunate group and the positive control group (P ＞ 0.05).Conclusion Artesunate can inhibit rosacea-like inflammatory reactions in mouse models,especially the middle-and high-dose artesunate.

Objective:To evaluate the efficacy and safety of endoscopic submucosal dissection (ESD) for early hypopharyngeal carcinoma and precancerous lesions.Methods:Clinical data of 41 patients who received ESD for early hypopharyngeal carcinoma and precancerous lesions from August 2013 to August 2019 in the Department of Endoscopy of Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College were retrospectively analyzed. Main outcome measurements included operation completion rate, operation time, en bloc resection rate, R0 resection rate, complication rate and recurrence.Results:ESD was successfully completed in all 41 cases, with a success rate of 100.0% and a mean time of 49.1 min (ranged 10-110 min). Fifty-four lesions underwent en bloc resection, with an en bloc resection rate of 98.2% (54/55), of which 41 had negative horizontal and vertical margins, and the R0 resection rate was 74.5% (41/55). During the operation of 55 lesions, there was a small amount of blood oozing on the wound surface, and electrocoagulation with thermal biopsy forceps could successfully stop the bleeding. No perforation occurred, and 2 cases (4.3%) had delayed bleeding after ESD, and hemostasis was successful under emergency endoscopy. Postoperative endoscopy showed that 1 case (2.2%) had esophageal entrance stenosis, and the obstruction was relieved after repeated water balloon dilatation. The follow-up period ranged from 3 to 72 months, and the median time was 18 months. One case was found to have mucosal lesions in the same part of the hypopharynx and received ESD treatment again. Follow-up to October 2020, no residual lesions and recurrence were found.Conclusion:ESD is a safe and effective option for the treatment of early hypopharyngeal carcinoma and precancerous lesions, which is worthy of clinical application.
