Herbal Textual Research on Polygonati Rhizoma in Famous Classical Formulas / 中国实验方剂学杂志

By consulting ancient Chinese herbal medicines and medical books， combined with modern documents， the textual research of Polygonati Rhizoma has been conducted to verify the name， origin， bitter-flavored Polygonatum species， Latin name evolution， origin， quality evaluation， harvesting and processing changes， so as to provide reference and basis for the development and utilization of the famous classical formulas. Through textual research， it can be seen that there are many other names for Polygonati Rhizoma， and Huangjing is the correct name since Mingyi Bielu. Based on the original research， it is concluded that P. sibiricum and P. cyrtonema were the mainstream of Polygonati Rhizoma before the Tang dynasty， and P. kingianum was added in the Qing dynasty. According to the shape of medicinal materials， these Polygonatum species were called Jitou Huangjing， Jiangxing Huangjing and Dahuangjing. The harvest time of Polygonati Rhizoma is spring and autumn. After harvest， it is steamed and dried in the sun， and its processing method is mainly "nine steaming and nine storms". Bitter-flavored Polygonatum is mainly P. cirrhifolium， P. zanlanscianense， P. curvistylum and P. verticillatum， which are not suitable for medicine. Based on textual research， it is recommended that when developing famous classical formulas and health products with Polygonati Rhizoma as the main raw material， the origin and producing area should be clear and fixed， and P. sibiricum or P. cyrtonema with clear origin should be used. It is necessary to conduct germplasm survey and sampling in the producing area， establish a planting base and a traceability system for Polygonati Rhizoma， in order to control the quality and stabilize the efficacy of the products. The processing method of Polygonati Rhizoma can be determined according to the product function positioning.

Herbal Textual Research on Pheretima in Famous Classical Formulas / 中国实验方剂学杂志

By consulting ancient herbal medicines and medical books， combined with modern documents and field investigations， the textual research of Pheretima has been conducted to verify the name， origin， producing area， quality， harvesting and processing changes， and sort out the relationship of origin between ancient and modern times， so as to provide reference and basis for the development and utilization of the related famous classical formulas. Through textual research， it is known that there are many aliases for Pheretima， the rectification of name was "Qiuyin" or "Baijing Qiuyin" in materia medica books. In the Song dynasty and later prescription books， the prescription name is mostly Dilong. From the beginning of Yaowu Chuchanbian （《药物出产辨》）， Dilong was used as the rectification of name. It is widely distributed in our country， which is produced all over the country and mostly wild. According to ancient Pheretima with "Baijing Dilong"， "Jingbai Shenzi" and "Datiao" as the principles of medicine， combined with historical origin， producing area and easy access， it is confirmed that Pheretima used in ancient times to the present is mainly Pheretima aspergillum， and it also has many other Qiuyin as Pheretima for medicinal purposes. Chinese Pharmacopoeia has unified the origin of the Pheretima since the 1995 edition based on historical origins and actual harvesting conditions. The medicinal material processed by P. aspergillum was called Guangdilong， and the medicinal materials processed by P. vulgaris， P. guillelmi and P. pectinifera were called Hudilong. Since then， all the herbal books published in the future are in line with Chinese Pharmacopoeia that was implemented at that time. The authentic production areas of Guangdilong are Guangdong and Guangxi， and the authentic production areas of Hudilong is Jiangsu， Shanghai， Zhejiang and Anhui. The Guangdilong produced in Guangdong and Guangxi has the best quality. After harvesting， remove the soil and offal， wash and dry. Clinically cut into sections for medicine， or prepare medicine according to prescription. The Pheretima in ancient used "Baijing Dilong"， "Jingbai Shenzi" and "Datiao" as the mainstream quality evaluation standards. According to historical origins， P. aspergillum should be the main source of Pheretima， and its quality is better than other species. Therefore， it is recommended that Pheretima in Shentong Zhuyutang use P. aspergillum， which is produced in Guangdong， Guangxi and other places. After harvest， the abdomen was opened in time to remove the viscera and sediment， washed and dried.

Market survey of Caryophylli Flos specifications / 中国中药杂志

The present study aimed to regulate the market circulation of Caryophylli Flos and formulate standards for commodity specifications and grades of Caryophylli Flos. Market survey was carried out in four major medicinal material markets with 48 samples of Caryophylli Flos collected. The property, 100-seed weight, impurity percentage, moisture, and eugenol content in Caryophylli Flos of different specifications from different producing areas were determined and analyzed. The results showed that 27.1% of the samples surveyed on the markets did not meet the requirements of Chinese Pharmacopoeia(2020 edition). The 100-seed weight and the property are important factors for the classification of Caryophylli Flos specifications. There were significant differences in the property, 100-seed weight, impurity percentage, and eugenol content in Caryophylli Flos samples of different specifications from different producing areas, and also differences in the proportions of different specifications in Caryophylli Flos samples from different producing areas. The African-originated Xiaohong(medium grade) and Guangxi-originated Xiaohong(medium grade) accounted for 70% and 66.7% respectively, the Indonesian-originated Dahong(top grade) for 56.2%. In conclusion, there are many problems in the circulation of Caryophylli Flos at present, mainly including the loss of origin information, no standards for specifications, non-implementation of grade standards, excessive impurities, and no evidence for authenticity identification. According to the classification of Caryophylli Flos specifications in this study, the average eugenol content of Xiaohong is significantly higher than the Dahong by 4.74%.

Assessing Adverse Effects of Aroclor 1254 on Perinatally Exposed Rat Offspring / 生物医学与环境科学（英文）

To assess the neurotoxic effects and redox responses of Aroclor 1254 (A1254) on perinatally exposed rat offspring, A1254 was administered by gavage from gestational day (GD) 6 to postnatal day (PND) 21. Neurobehavioral development, antioxidant enzyme activities, lipid peroxidation (LPO), nitric oxide (NO), and NO synthase (NOS) levels were analyzed in the offspring. Neurobehavioral development analysis revealed delayed appearance of the righting reflex, negative geotaxis, and cliff drop test responses in A1254 exposed group. Developmental A1254 exposure also caused oxidative stress in the brain of PND 22 offspring via reductions in the activity of SOD and GSH-Px, and by promoting a rise in the levels of NO and NOS.
