RESUMO
Danggui Sinitang is first recorded in the Treatise on Cold Damage written by ZHANG Zhongjing in the Han dynasty. It is composed of Angelicae Sinensis Radix， Cinnamomi Ramulus， Paeoniae Radix Alba， Asari Radix et Rhizoma， Glycyrrhizae Radix et Rhizoma， Tetrapanacis Medulla， and Jujubae Fructus and serves as a classic formula for treating the syndrome of blood deficiency and cold reversal. This study systematically reviews the records of Danggui Sinitang in ancient Chinese medicine books of various dynasties and the modern clinical applications to probe into the composition， plant species， processing， dosage， decocting method， and indications of Danggui Sinitang， aiming to provide a reference for the development and clinical application of this classic formula. The review of the records showed that there were a variety of records of Danggui Sinitang with different composition， and the composition of this formula listed in the Treatise on Cold Damage has a significant impact on later generations and has been used by medical practitioners throughout history. Although the dosage of some drugs decreased during the Ming and Qing dynasties， the medical practitioners continued to use the original formula. In terms of processing， although there were slight changes in the processing of Angelicae Sinensis Radix， Paeoniae Radix Alba， Glycyrrhizae Radix et Rhizoma， and Tetrapanacis Medulla， the original processing method was inherited. In terms of indications， Danggui Sinitang was designed to treat cold reversal due to blood deficiency and dysentery. Furthermore， it was used to treat headache， convulsive disease， infantile convulsion， and private part adduction in the Ming and Qing dynasties. Nowadays， this formula is mostly used to treat diabetes peripheral neuropathy， rheumatoid arthritis， dysmenorrhea， Raynaud's disease and other diseases. In terms of precautions， ancient physicians believed that Danggui Sinitang should not be taken by pregnant women and should only be used for limb chills caused by blood deficiency and cold coagulation. For limb chills caused by other reasons， this formula should not be used indiscriminately. Modern research has not reported any serious adverse reactions related to this formula. Danggui Sinitang has a definite therapeutic effect. In subsequent research and development， quality control standards of Danggui Sinitang should be established while its safety is ensured， and the related preparations should be developed and applied.

Considering the existence of large individual differences and unclear mechanisms of action in the clinical application of progestins, this paper aims to provide an overview of the current clinical application status, efficacy, hormone resistance, and its mechanisms in the context of hormone therapy.
RESUMO
Simmering method is one of the traditional processing methods of Chinese materia medica， which has been documented in the herbal literature and medical books of the past dynasties and has a great variety， but at present， there are not many specific varieties of Chinese materia medica involved， and there are few related researches. By reviewing the ancient and modern related information， the authors have organized and analyzed the historical evolution， processing purpose， modern representative Chinese materia medica（processing technology， quality evaluation， pharmacological research） of simmering method. After sorting out， it was found that the simmering method was widely used in ancient times， which was first seen in Huashi Zhongzangjing of the Eastern Han dynasty， and was enriched and developed through the Tang， Song， Jin， Yuan， Ming and Qing dynasties， and entered its heyday in Ming and Qing dynasties along with the economic prosperity and development of the Ming dynasty， involving as many as 159 varieties of Chinese materia medica， and gradually perfecting the processing theory of the simmering method. However， the number of varieties that still use the simmering method in modern times significantly decreased. The main purposes of using simmering method in modern Chinese materia medica are to reduce adverse reactions， moderate medicinal properties， enhance therapeutic effects， remove non-medicinal parts， and facilitate further processing， etc. This paper combed the key information of simmering methods for Chinese materia medica from ancient to modern times， which can provide a literature basis for the clinical application and modern research of simmered products of Chinese materia medica.
RESUMO
Huangqitang comes from the Taiping Huimin Hejiju Fang of the Song dynasty. It consists of four medicinal materials: Astragalus membranaceus var. mongholicus, Citrμs reticμlata， Cannabis sativa， and Apis cerana. It is a classic prescription for treating constipation in the elderly. This study systematically collated the literature records about Huangqitang in ancient Chinese medicine books and combined it with the current status of modern clinical applications to conduct in-depth analysis and research on the origin，composition， dosage, processing, preparation and administration, drug base, main symptoms， and other key information of the formula, so as to provide a strong reference for the development and clinical application of the classic Huangqitang compound preparation. Through systematic combing and textual research on the previous literature of Huangqitang， it can be seen that the formula of Huangqitang was first recorded in the Taiping Huimin Hejiju Fang， and the medical books of the past dynasties mostly adopted this formula. In terms of drug base， the dried roots of the leguminous plant Astragalus membranaceus var. mongholicus are used， and for tangerine， the dried outer peel of the Rutaceae plant Citrus reticμlata and its cultivated varieties are used. The Moraceae plant Cannabis sativa with the peel removed is selected, and the Apis cerana is selected from the honey brewed by Apis cerana， an insect of the Apidae family. In terms of dosage， although the dosage of some drugs changed during the Ming and Qing dynasties, the dosage records basically followed the original prescriptions from the Song dynasty. In terms of processing, preparation, and usage， although the drug processing， preparation， and usage of Huangqitang in the medical books of the past dynasties have changed slightly， they are basically the same as the original prescription of the Song dynasty. In terms of main symptoms, Huangqitang is designed to treat constipation in the elderly. From the Song dynasty to the Qing dynasty， it was mostly used to treat constipation， secret congestion, asthenia， etc. in the elderly. In modern times， it is clinically used to treat constipation due to Qi deficiency， functional constipation， irritable bowel syndrome， and other diseases in the elderly. No adverse reactions have been found yet. In the subsequent research and development， it is necessary to carry out mass spectrometry analysis of Huangqitang， in-depth exploration of its prescription efficacy and mechanism of action， and other multi-omics scientific research. At the same time， it is important to establish quality control standards to provide a reliable scientific basis for the research and development, clinical treatment， and drug supervision of Huangqitang compound preparations.

RESUMO
Photodynamic therapy (PDT) is a new modality for cancer therapy, which has been used in the clinical treatment for various tumors, such as skin cancer, bladder cancer and prostate cancer. Most photosensitizers have the disadvantages of hydrophobic, low bioavailability and the limited tumor targeting ability. The nanoscale delivery systems can improve the solubility of photosensitizers and enhance their accumulation at the tumor sites. The multifunctional nano-delivery systems are prepared in combination with other anti-tumor drugs to enhance the anti-tumor effect. In addition to addressing the issues of poor solubility and the insufficient tumor targeting ability, the nanoscale delivery systems need to improve the pharmacokinetic properties of photosensitizers, facilitating their rapid accumulation at the tumor sites and quick elimination in vivo, and reducing the skin phototoxicity. This review summarizes the recent clinical application of PDT of cancer, the development of photosensitizers, the delivery systems for photosensitizers and the combinatorial application with other therapeutic methods. The goal is to present an understanding of knowledge on the design of new types of photosensitizers and its clinical application in PDT of cancer.
