The classic formula Wuyaotang is the 49th of the 100 formulas in the Catalogue of Ancient Classic Prescriptions (First Batch) issued by the National Administration of Traditional Chinese Medicine, and is from the Secrets from the Orchid Chamber (《兰室秘藏》) by LI Dongyuan of the Jin Dynasty. It is composed of Angelicae Sinensis Radix, Glycyrrhizae Radix et Rhizoma, Aucklandiae Radix, Linderae Radix, and Cyperi Rhizoma, and has the effect of moving Qi, regulating meridians, and relieving pain. It is mainly indicated for Qi stagnation and blood stasis syndrome. Based on the ancient books on Wuyaotang, this study systematically reviewed the formula source, composition, dosage, preparation, usage, functions, indications, preparation principle, drug processing, modification, etc. of Wuyaotang with the bibliometrics method, explored its historical evolution, and determined the key information. Statistical analysis of its modern literature shows that there are few studies of the original formula of Wuyaotang, and the clinical studies mainly focus on modified Wuyaotang. It has a wide range of treatment scope and can be used for the treatment of dysmenorrhea, delayed menstrual cycle, hypomenorrhea, and menstrual fever, as well as ulcerative colitis, spleen distortion, sciatica, child intestinal spasm, and other internal, surgical, gynecological, and pediatric diseases. The pathogenesis in traditional Chinese medicine (TCM) is Qi stagnation. Through the analysis and research on ancient books and modern literature recording Wuyaotang, this study is expected to provide a scientific basis for the clinical application, in-depth research, and development of the classic formula Wuyaotang.

Historical Evolution and Modern Clinical Application of Danggui Liuhuangtang / 中国实验方剂学杂志

Danggui Liuhuangtang is the 47th of the 100 famous classical formulas published by the National Administration of Traditional Chinese Medicine， and is known as the holy medicine for night sweat. By bibliometrics， the authors collected the ancient books on Danggui Liuhuangtang and screened out 269 valid data， involving 156 ancient books of traditional Chinese medicine. The analysis on the historical origin， disease syndromes， pathogenesis， composition， dosage， preparation， usage， and processing of Danggui Liuhuangtang found that this famous classical formula originated from Secret Book of the Orchid Chamber （《兰室秘藏》） written by LI Dongyuan， and is composed of Angelicae Sinensis Radix， Rehmanniae Radix， Rehmanniae Radix Praeparata， Phellodendri Chinensis Cortex， Scutellariae Radix， Coptidis Rhizoma and Astragali Radix. It has the functions of nourishing Yin， reducing fire， consolidating exterior and stopping sweating， and mainly treats night sweat due to Yin deficiency and fire exuberance. In the later generations， disease syndromes are mostly treated based on LI Dongyuan's theory， and have expanded to more than 30 kinds （339 in total）， among which night sweat （208） was the most， accounting for 61.36% of the total disease syndromes， followed by spontaneous sweating （38）， accounting for 11.21%. Additionally， it was found that Danggui Liuhuangtang was widely used in modern clinical practice for various disease syndromes. Among them， endocrine disease （77， 28.21%） was predominant， followed by gynecological disease （48， 17.58%）， and pediatric disease （24， 8.79%）. Although Danggui Liuhuangtang treats many disease syndromes， their pathogenesis was always yin deficiency and fire exuberance. Through the systematic excavation of the ancient books on Danggui Liuhuangtang and the analysis of its modern clinical application， this paper probed into the historical evolution and confirmed the key information of the formula， providing detailed literature basis for the research and development application of famous classical formulas.

Historical Evolution and Modern Clinical Application of Shengyang Yiweitang / 中国实验方剂学杂志

Shengyang Yiweitang is one of the first 100 classical prescriptions published by the National Administration of Traditional Chinese Medicine. It originated from the Clarifying Doubts about Damage from Internal and External Causes by physician LI Dongyuan of Jin dynasty， and is composed of Astragali Radix， Ginseng Radix et Rhizoma， Glycyrrhizae Radix et Rhizoma， Atractylodis Macrocephalae Rhizoma， Poria， Pinelliae Rhizoma， Citri Reticulatae Pericarpium， Angelicae Pubescentis Radix， Saposhnikoviae Radix， Notopterygii Rhizoma et Radix， Bupleuri Radix， Paeoniae Radix Alba， Alismatis Rhizoma， and Coptidis Rhizoma. With the effects of replenishing Qi， promoting Yang， clearing heat and removing dampness， Shengyang Yiweitang is used to treat spleen-stomach weakness and dampness-heat accumulation syndrome. Using bibliometrics， the authors systematically sorted out the source，composition， dosage， preparation， efficacy， indications， principle of composition， origin and processing of drugs，and modern clinical application of the prescription， and explored its history and key information. Additionally， it was found that Shengyang Yiweitang was widely used in modern clinical practice and was suitable for multisystem diseases， of which digestive system （264） was the most common， accounting for 41.71%， followed by urogenital system （57， 9.00%） and nervous system （48， 7.58%）. Although the treatment scope was wide， the pathogenesis of the diseases in traditional Chinese medicine belongs to "spleen-stomach weakness"， which fully reflected Li's academic thought of "internal injury of spleen and stomach leads to various diseases". The key information of Shengyang Yiweitang was determined by summarizing the relevant ancient books and modern literature， so as to provide accurate reference for its rational clinical application and further research and development.

Characteristics and influencing factors of esophageal stenosis after endoscopic submucosal dissection for early esophageal carcinoma / 中华消化内镜杂志

Objective:To investigate the characteristics and influencing factors of esophageal stenosis after endoscopic submucosal dissection (ESD) for early esophageal carcinoma.Methods:Patients who underwent ESD in the Digestive Endoscopy Center of the Second Affiliated Hospital of Army Medical University from January 2011 to December 2018 were included. The data were obtained from medical records and follow-up. The influencing factors of stenosis were determined by single factor and Cox regression analysis.Results:A total of 654 patients underwent ESD and 79 (12.1%) of them developed postoperative esophageal stenosis. The median time of stenosis development was 27 (17, 43) days. The morphology and lesion circumferential proportion were independent factors for the occurrence of stenosis after ESD. The stenosis incidence of type Ⅱa was 6.601 times (95% CI: 1.518-28.709, P=0.012) compared with that of type Ⅱc. The incidence of stenosis in lesions with 75%-<100% and 100% circumference was 17.408 times (95% CI: 8.009-37.839, P<0.001)and 52.439 times (95% CI: 23.905-115.029, P<0.001) respectively compared with that of patients <75%. Among the 79 patients, 27 had severe stenosis, and the lesion circumferential proportion was an independent factor for stenosis. Compared with the group of lesion circumferential proportion of less than 75%, the incidences of stenosis of lesion circumferential proportion of 75%-<100% and 100% were 7.775 (95% CI: 1.977-30.577, P=0.003) and 70.062 (95% CI: 19.879-246.926, P<0.001) times respectively. Conclusion:The morphology and lesion circumferential proportion are two independent factors for the occurrence of esophageal stenosis after ESD. Additionally, lesion circumferential proportion is an independent factor for the occurrence of severe esophageal stenosis after ESD.

Research on feasibility and effectiveness of the bone-implant contact evaluation in dogs by micro-CT / 中华口腔医学杂志

Objective@#To discuss the feasibility and effectiveness of using micro-CT in bone-implant contact (BIC) evaluation in dogs, and to provide reference for clinical and scientific research.@*Methods@#Bilateral mandibular second premolar and first molar of six male Beagle dogs were extracted. After 3 months′ healing, eight implants were placed in bilateral mandible of each dog, four on each side. Dogs were sacrificed at 2 weeks, 4 weeks and 8 weeks after implant placement, two on each time point. Samples were scanned with micro-CT and digitally reconstructed. Bone-implant interface was analyzed at different analysis regions (25, 50 and 100 μm from implants′ surface), different detection range models were obtained (each time point consists 48 models), and BIC was evaluated, and the results were counted as micro-CT25, micro-CT50, and micro-CT100 groups. Then undecalcified slides were made (three slides for each sample) and stained with toluidine blue for observation and analysis of BIC using an optical microscope, and the results were counted as optical microscope groups. The advantages and disadvantages, evaluation efficiency and BIC of different methods were analyzed.@*Results@#To evaluate BIC of single sample, it took about 90 minutes by micro-CT, which was much lower than the time of 14 days by optical microscope. The success rates of modeling of micro-CT25, micro-CT50, and micro-CT100 groups all were 100.0% (48/48), and total success rate of micro-CT group was 100.0% (144/144). For optical microscope groups, the success rates of making slides 2, 4, 8 weeks were 89.6% (43/48), 93.8% (45/48) and 93.8% (45/48), respectively, and total success rates of optical microscope group was 92.4% (133/144). At 2, 4,8 weeks after implantation, BIC in micro-CT25 group was significantly smaller than that in optical microscope group at the same time point (P<0.05). However, at 2, 4,8 weeks after implantation, BIC of the micro-CT50 and micro-CT100 groups showed no significant difference with optical microscope groups at the same time point (P>0.05). A significant correlation (P<0.001, each) was seen between slides and micro-CT (25, 50, 100 μm groups) concerning BIC (r=0.680, r=0.892, r=0.713), and error bias was -19.4%, -0.9%, 3.0%, respectively. The probability within the 95% limits of agreement were 97.9%.@*Conclusions@#Micro-CT is a faster, simpler and more efficient way to analyze BIC at the implant-bone interface than optical microscope observation. BIC analysis by selecting 50 μm from implants′ surface as analysis region using micro-CT is in consistent with that using the optical microscope.
