Daochisan is a pediatric famous classical formula in traditional Chinese medicine（TCM） specializing in clearing the heart， disinhibiting water and enriching Yin， which has been inherited and developed by medical experts of successive generations. The formula can be traced back to Xiaoer Yaozheng Zhijue written by QIAN Yi from Song dynasty， and most of the later-developed Daochisan（Daochitang） is based on this formula with additions and subtractions. So as to promote the literature excavation of this formula， this paper conducts a thorough textual research and analysis of the composition， processing， preparation methods， clinical applications of Daochisan based on a systematic collation of relevant ancient and modern literature in the method of bibliometrics. A total of 127 pieces of data involving 86 antient TCM books were collected. Statistical analysis showed that the drug origin of Daochisan is basically clear， we suggest that Rehmanniae Radix is the root tuber of Rehmannia glutinosa of Scrophulariaceae， Akebiae Caulis is the dry stem of Akebia quinata of Lardizabalaceae， Glycyrrhizae Radix et Rhizoma is the dry root and stem of Glycyrrhiza uralensis of legume， bamboo leaf is the dry leaves of Phyllostachys nigra var. henonis of gramineous plants. Four herbs are recommended to use its raw products. The key information of the dosage and decocting method is supposed to be "4.13 g each of raw Rehmanniae Radix， raw Glycyrrhizae Radix et Rhizoma， Akebiae Caulis， adding 300 mL of water， and then adding 4.13 g of bamboo leaf， decocting together to 150 mL， taking warmly after meal". Daochisan has the effect of clearing the heart and enriching Yin， disinhibiting water and relieving stranguria， and is widely used in treating symptoms such as heart vexed hotness， hydrodipsia and reddish complexion. Modern studies have showed that Daochisan are frequently used in treating oral ulcer， herpetic stomatitis， urinary tract infection， herpes zoster and other diseases. The above research results can provide scientific reference for the future development and research of Daochisan.

Yinchenhao Tang has definite clinical efficacy. It has been inherited and documented since the ancestor of Shanghanlun in the Eastern Han dynasty and is a classical formulas for clearing away heat， promoting diuresis， and eliminating jaundice adopted by medical experts of successive generations. It has been included in the Catalogue of Ancient Classical Formulas （the Second Batch of Han Medicine） published by the National Administration of Traditional Chinese Medicine （TCM） in 2023. By means of bibliometrics， 801 pieces of ancient literature data related to Yinchenhao Tang were collected， and 36 pieces of effective data were selected， involving 36 ancient books of TCM. The origin， name， composition， efficacy， formula and meaning analysis， drug origin， dosage， preparation method and usage， indications， and modern clinical application of Yinchenhao Tang were analyzed. It was suggested that the modern dosage and application of Yinchenhao Tang should be as follows： The 82.8 g of Artemisiae Scopariae Herba， 12.6 g of Gardeniae Fructus， and 27.2 g of Rhei Radix et Rhizoma. The formulas was prepared by firstly adding 2 400 mL of water into Artemisiae Scopariae Herba and boiling it to about 1 200 mL， then adding Gardeniae Fructus and Rhei Radix et Rhizoma to boil it for 600 mL， and removing the residue. It could be orally taken for 200 mL each time in warm conditions， three times a day. Yinchenhao Tang has the effect of clearing away heat， promoting diuresis， and eliminating jaundice， and it mainly treats symptoms of hygropyretic jaundice. In the formulas， Yinchenhao Tang is the monarch drug， which is mainly to remove dampness and jaundice. Gardeniae Fructus is the ministerial drug， which is mainly responsible for clearing the triple energizer and facilitating urination. Rhei Radix et Rhizoma is an adjuvant， mainly responsible for clearing away heat and eliminating jaundice. The modern application of this formulas involves the hepatobiliary system， skin system， endocrine system， digestive system， etc.， and it has more advantages in treating jaundice， icteric hepatitis， and hepatitis B. In this study， the ancient literature related to Yinchenhao Tang was sorted out to determine its key information， so as to provide a scientific reference for clinical application of classic formulas and new drug development.

This paper discussed the historic evolution of Juanbitang and similar decoctions， clarified the historic development of Yangshi Juanbitang and Chengshi Juanbitang， and probed into the key information of the meaning， original plants， processing methods， and modern dosage and usage of Chengshi Juanbitang. A total of 267 pieces of relevant information were collected from ancient traditional Chinese medicine （TCM） books， among which 53 pieces of effective data were included in this study. The results showed that both Chenshi Juanbitang and Yangshi Juanbitang were originated from Duhuo Jishengtang recoded in the Important Prescriptions Worth a Thousand Gold for Emergency （Bei Ji Qian Jin Yao Fang）. According to the standard of "1 qian roughly equals 3.73 g" in the measurement system of the Qing Dynasty， we suggest Chenshi Juanbitang is composed of 3.73 g Notopterygii Rhizoma et Radix， 3.73 g Angelicae Pubescentis Radix， 3.73 g Gentianae Macrophyllae Radix， 11.19 g Angelicae Sinensis Radix， 11.19 g Mori Ramulus， 2.61 g Chuanxiong Rhizoma， 1.87 g Cinnamomi Cortex， 1.87 g stir-fried Glycyrrhizae Radix et Rhizoma， 7.46 g Piperis Kadsurae Caulis， 2.98 g Olibanum， and 2.98 g Aucklandiae Radix， which should be decocted with 600 mL water to reach a volume of 300 mL. The decoction should be taken 3 times a day before meals. Juanbitang， a classical formula specialized for treating impediment diseases， has the effects of dispelling wind， removing dryness， and alleviating impediment to relieve pain. It can be used for treating vexing pain in body， spasm of nape and back， and heaviness in waists and legs. Modern studies have shown that Juanbitang can be used for treating rheumatoid arthritis， knee osteoarthritis， and periarthritis of shoulder. The above results served as a reference for the future development of Juanbitang.

The study aims to explore the effect of mesenchymal stem cells-derived exosomes (MSCs-Exo) on staurosporine (STS)-induced chondrocyte apoptosis before and after exposure to pulsed electromagnetic field (PEMF) at different frequencies. The AMSCs were extracted from the epididymal fat of healthy rats before and after exposure to the PEMF at 1 mT amplitude and a frequency of 15, 45, and 75 Hz, respectively, in an incubator. MSCs-Exo was extracted and identified. Exosomes were labeled with DiO fluorescent dye, and then co-cultured with STS-induced chondrocytes for 24 h. Cellular uptake of MSC-Exo, apoptosis, and the protein and mRNA expression of aggrecan, caspase-3 and collagenⅡA in chondrocytes were observed. The study demonstrated that the exposure of 75 Hz PEMF was superior to 15 and 45 Hz PEMF in enhancing the effect of exosomes in alleviating chondrocyte apoptosis and promoting cell matrix synthesis. This study lays a foundation for the regulatory mechanism of PEMF stimulation on MSCs-Exo in inhibiting chondrocyte apoptosis, and opens up a new direction for the prevention and treatment of osteoarthritis.

Enhancers activate transcription in a distance-, orientation-, and position-independent manner, which makes them difficult to be identified. Self-transcribing active regulatory region sequencing (STARR-seq) measures the enhancer activity of millions of DNA fragments in parallel. Here we used STARR-seq to generate a quantitative global map of rice enhancers. Most enhancers were mapped within genes, especially at the 5' untranslated regions (5'UTR) and in coding sequences. Enhancers were also frequently mapped proximal to silent and lowly-expressed genes in transposable element (TE)-rich regions. Analysis of the epigenetic features of enhancers at their endogenous loci revealed that most enhancers do not co-localize with DNase I hypersensitive sites (DHSs) and lack the enhancer mark of histone modification H3K4me1. Clustering analysis of enhancers according to their epigenetic marks revealed that about 40% of identified enhancers carried one or more epigenetic marks. Repressive H3K27me3 was frequently enriched with positive marks, H3K4me3 and/or H3K27ac, which together label enhancers. Intergenic enhancers were also predicted based on the location of DHS regions relative to genes, which overlap poorly with STARR-seq enhancers. In summary, we quantitatively identified enhancers by functional analysis in the genome of rice, an important model plant. This work provides a valuable resource for further mechanistic studies in different biological contexts.

Objective To establish and verify the fluctuation of reference intervals for biochestry parameters in routine physical exami-nation. Methods The results of biochemistry parameters,i.e., total protein (TP), albumin (Alb), total bilirubin (T-Bil), alanine aminotransferase (ALT), glucose (Glu), urea (Urea), creatinine (Cr), uric acid (UA), triacylglycerol (TG) and total cholesterol ( TC) from 2 089 healthy subjects in routine physical examination during consecutive 2014, 2015 and 2016 were randomly collected, in which all the results were within the reference range. The ratio (λ1) of the results of 2015 to those of 2014, and ratio (λ2) of the re-sults of 2016 to those of 2015 were calculated. λ1was analyzed statistically to establish the fluctuation of reference interval (CIλ). CIλ was verified by λ2.The personalized reference interval (CIp) was established by multiplying each result of 2015 and the upper and low-er limits of CIλ. The CIpwas verified by the results of 2016. The ratios of CIpto the upper and lower limits of conventional reference in-terval were calculated. Results The values of CIλwere as follows: TP: 0.91 to 1.08, Alb: 0.91 to 1.08, T-Bil: 0.58 to 1.74, ALT:0.49 to 1.99, Glu: 0.84 to 1.20, Urea: 0.67 to 1.50, Cr: 0.82 to 1.22, UA: 0.77 to 1.32, TG: 0.51 to 1.98 and TC: 0.80 to 1.26. Compared with conventional reference interval, the ratio of the upper and lower limits of CIp was lessened. Conclusion The personal-ized reference interval (CIp) which may increase the sensitivity of conventional reference intervals was established and verified.
