摘要
As the pace of society increases and lifestyles change, the incidence and mortality rates of breast cancer continue to rise. Targeted therapies are now promising in the treatment of breast cancer, and a variety of protein targets have been identified to play an important role in the development of breast cancer. Among them, signal transducer and activator of transcription (STAT) proteins constitute a crucial group that serves as important targets for transducing cellular transcriptional information, which can regulate downstream cell proliferation, apoptosis, cell migration, invasion, angiogenic factors, etc. and then affect the progression of breast cancer. The STAT family is closely associated with the inflammatory response to tumors and plays a landmark role in tumor development as well as in diagnosis and prognosis. The "inflammation-cancer" transformation refers to the process in which the inflammatory microenvironment caused by uncontrolled inflammation promotes normal cells to become cancerous. According to the theory of Chinese medicine, "heat toxicity" in "cancer toxicity" corresponds to inflammation, which is closely related to tumor development. As a major link associated with the inflammatory response, the STAT family has a promising role in the development and treatment of a variety of tumors, but its relevance to breast cancer remains inadequately explored. Chinese medicine has been shown to have good efficacy in the prevention and treatment of breast cancer, and some current studies have shown that the active ingredients and compounds of Chinese medicine have certain intervention effects on breast cancer-related STAT proteins, but there has not been a systematic review. In order to better sort out and summarize the studies on the effects of Chinese herbal medicines based on the STAT family interventions in breast cancer, this paper reviewed the studies on Chinese herbal medicines acting on the STAT family in recent years, aiming to provide new ideas for clinical applications in breast cancer and to provide thoughts for the development of STAT protein-based drugs.

摘要
The transcription factor ZNF24 (also known as ZNF191 or KOX17) is a member of the Krüppel-like zinc finger transcription factor family, with a leucine-rich (Leu) SCAN domain (also known as LeR domain) at the N-terminus and four consecutive typical Kruppel-like zinc finger modities at the C-terminus. ZNF24 is a multifunctional transcription factor involved in the regulation of kinase transcriptional activity, vascular proliferation and development, especially in tumorigenesis and tumor progression. ZNF24 plays an important and complex dual-directional regulation role (promoting and inhibiting) in tumor development, invasion and metastasis by regulating the transcriptional expression of different target genes (such as VEGF, Wnt8B, Twist1, β-catenin and DGL1, etc.) and the competitive binding with protein factors (such as β-catenin). Therefore, elucidating the mechanism of ZNF24 in tumors would provide clues and ideas for the treatment of tumors. The researches status of ZNF24 in tumors were summarized in this paper.

摘要
Esophageal cancer is a digestive tract malignancy with high morbidity and mortality and mainly occurs in males. The 5-year survival rate is lower than 20%. In China, the morbidity and mortality of esophageal cancer rank the first in the world, seriously threatening national health. The pathogenesis of esophageal cancer is diverse, which is generally considered as the consequence of environmental-genetic-gene interaction. In addition to genetic factors and regional characteristics, gene mutation, RNA interference, DNA damage repair, tumor microenvironment, dietary habit, chronic adverse stimulation, and inflammatory reaction are all involved in the occurrence and development of esophageal cancer. However, there is no unified and accurate conclusion. Clarifying the exact pathogenesis of esophageal cancer is of great significance for its early screening, diagnosis, prevention, treatment, and prognosis. Surgery, radiotherapy, and chemotherapy are the three effective methods for the treatment of esophageal cancer. However, due to the atypical early symptoms, most patients have missed the best operation period when diagnosed, resulting in poor clinical prognosis. Moreover, radiotherapy and chemotherapy will cause side effects such as loss of appetite, low immune function, esophagitis, pneumonia, and malnutrition, which is not conducive to the prognosis and treatment maintenance of patients. With definite efficacies on esophageal cancer, traditional Chinese medicine (TCM), which is flexible and diverse in the treatment, can primarily or alternatively be involved in the treatment of esophageal cancer. TCM can eliminate postoperative complications and postoperative infections and relieve adverse gastrointestinal reactions, weakened immune function, and organ damage caused by radiotherapy and chemotherapy. It can enhance clinical efficacy and improve the quality of life of patients. Therefore, it is necessary to systematically summarize the clear pathogenesis or risk factors of esophageal cancer and review the clinical characteristics of TCM in the prevention and treatment of esophageal cancer to facilitate the early screening, diagnosis, and treatment of esophageal cancer and promote the application of TCM in the prevention and treatment of esophageal cancer and related adverse reactions.

Objective:To analyze the changes of metabolic indexes and other characteristics in patients with primary aldosteronism (PA) and improve the understanding of PA.Methods:From January 2017 to August 2020, 91 PA patients who were clearly diagnosed and met the inclusion conditions in Tangshan workers Hospital, Hebei Medical University were selected as the observation object (PA group), and 112 patients diagnosed as essential hypertension (EH) in the same period were included as the control (EH group). A retrospective case-control study was conducted to compare the differences of blood glucose, blood lipid, homocysteine, blood potassium, creatinine, uric acid, aldosterone, renin, plasma aldosterone to renin ratio (ARR), blood pressure and waist circumference between the two groups. The measurement data of normal distribution were compared by independent sample t-test. The non normal distribution data are represented by M (Q 1, Q 3), and the rank sum test is used for inter group comparison. Comparison of counting data χ2 inspection. Logistic regression was used in multivariate analysis. Results:Univariate analysis showed that serum potassium, renin and ARR were (3.37±0.39) mmol/L, 1.61 (0.34, 7.23) ng/L and 96.85 (26.06, 506.10) in PA group and (3.91±0.59) mmol/L, 12.81 (1.90, 82.45) ng/L and 13.22 (1.06, 54.63) in EH group ( t=3.35, z=6.24, z=55.40, all P<0.001). In PA group, systolic blood pressure was (190.80±20.30) mmHg, diastolic blood pressure was (117.70±12.89) mmHg, waist circumference was (91.67±9.38) cm, and in EH group, systolic blood pressure was (177.01±12.89) mmHg, diastolic blood pressure was (101.39±9.34) mmHg, waist circumference was (86.59±9.07) cm. There were significant differences between the two groups ( t=5.88, 10.44, 3.90; all P<0.001). Multivariate logistic regression analysis showed that waist circumference (OR=1.065, 95% CI 1.007-1.118, P<0.001), systolic blood pressure (OR=1.053, 95% CI 1.034-1.077, P<0.001), diastolic blood pressure (OR=1.054, 95% CI 1.031-1.077, P<0.001), and ARR (OR=1.170, 95% CI 1.115-1.228, P<0.001) were the risk factors for PA. Conclusion:Compared with essential hypertension, PA patients have higher blood pressure, ARR and waist circumference, lower blood potassium and renin levels. Systolic blood pressure, diastolic blood pressure, ARR and waist circumference are the risk factors of PA. Strengthening the screening and treatment of PA in high-risk groups is helpful to better avoid the risk of target organ damage.
摘要
Endoplasmic reticulum (ER) is an important organelle responsible for protein, steroid, lipid and carbohydrate synthesis and calcium-dependent signal transduction in eukaryotic cells. ER homeostasis is essential for normal cell function. ER homeostasis imbalance can induce ER stress (ERS), which participates in the occurrence and development of diseases of the digestive system, respiratory system, circulatory system, nervous system, reproductive system, and endocrine system, and affects body health. Among various diseases, cancers seriously endanger people′s health due to its high mortality rate, disability rate, and recurrence rate. Due to the survival characteristics of unlimited proliferation, tumor cells are often exposed to various internal and external stimuli such as hypoxia, ischemia, excessive proliferation, and starvation, which destroy intracellular protein balance and induce ERS to some extent for survival. ERS plays a major role in various tumors and has dual functions in the survival of tumor cells: promoting the survival of tumor cells by activating a series of adaptive responses, while inducing ERS-related apoptosis pathways, so as to promote tumor cell death and inhibit tumor growth and invasion. As multiple functions of ERS in tumors are reported, many scholars have tried to intervene in the progress of tumors from the perspective of ERS. The therapeutic effect of traditional Chinese medicine (TCM) on tumors has been widely recognized. TCM can participate in the regulation of tumors from many aspects, including ERS, chemoradiotherapy resistance, gastrointestinal adverse reactions caused by chemotherapy, postoperative recurrence and metastasis. Since there are few reports on the antitumor effect of TCM from the perspective of ERS, this paper expounds the influence of ERS on tumorigenesis and development and the progress of TCM intervention in tumor through ERS, in order to provide a new direction for tumor treatment.

摘要
Based on the clinical characteristics of chronic atrophic gastritis in traditional Chinese and Western medicine, the domestic and foreign relevant literature reports and animal models of chronic atrophic as well as the clinical diagnostic indicators of traditional Chinese and western medicine, chronic atrophic gastritis evaluation standard was summarized to evaluate and analyze the coincidence degree of clinical symptoms of the existing chronic atrophic gastritis animal models. The statistical results found that modeling methods with a higher coincidence degree with the existing chronic atrophic gastritis animal models are disease and syndrome combination mode-ling, surgical modeling, multifactor comprehensive modeling and MNNG modeling. Although the animal models were reproduced by such methods as etiology, pathogenesis and disease and syndrome combination similar to those of human beings, there is still a big gap with the natural disease state. Further in-depth studies and improvement shall be made in clinical practice in the hope to provide refe-rence for clinical practice and experimental studies of chronic atrophic gastritis.

摘要
Knee osteoarthritis(KOA) is a common orthopedic disease. Its main symptoms include pain in the medial knee, aggravated knee pain during walking, limited movement, and joint deformity, which seriously affect the daily life of patients. The replication of animal models consistent with clinical symptoms is the premise of KOA-related experimental research. Based on the clinical characteristics of KOA and Western medicine, this paper discusses the existing KOA animal model, and analyzes the clinical anastomosis of the existing model based on the clinical diagnostic criteria of KOA. Through analysis and comparison, it can be seen that most of the existing modeling methods are single-factor animal models, which have a certain gap with the characteristics of KOA caused by clinical multi-factors and interaction. Moreover, modeling methods are mostly guided by Western medicine, and traditional Chinese medicine pathogenic factors are absent in the modeling process. Only cold stimulation method takes cold and wet into account. In the evaluation of the model, knee swelling, pain and articular rickets were the main evaluation criteria, which were different from the diagnostic criteria of Chinese and Western medicine in KOA. In terms of syndrome differentiation and classification, KOA is divided into kidney vacuity and deficiency of marrow, Yang vacuity and cold coagulation, and blood stasis and arrest in traditional Chinese medicine. The exis-ting animal models often confuse KOA with each other. Only cold stimulation method is used to establish KOA of Yang vacuity and cold coagulation. Therefore, in this paper, based on KOA clinical symptoms between Chinese and Western medicine features, analysis of the existing animal models, for further improving KOA animal models, the standardization of the model to evaluate suggestions, in order to improve the animal models and clinical inosculation between Chinese and Western medicine, the KOA animal model to better serve the scientific research work, promote the related mechanism, pathological changes and drug screening.

The pathogenesis of chloasma is complex and diverse. Traditional Chinese medicine (TCM) believes that it is mostly related to liver, spleen and kidney, with hematogenous impassability as the standard and pigmentation on the face or body surface as the main symptom. Western medicine believes that it is closely related to family inheritance, ethnic differences and ultraviolet radiation. At present, there are various clinical therapies, mainly including prevention of ultraviolet radiation, local whitening agent and chemical skin. In addition, TCM plays an important role in the treatment of chloasma, often involving internal use, topical use, acupuncture and moxibustion. Modern studies have shown that TCM therapies mainly regulate the metabolism of antioxidant, endocrine and melanin in vivo. Although the mechanism of action could not explained to some extent, there are still some restriction in the discussions on the mechanism of external use of TCM in controlling chloasma. As the skin nerve-endocrine-immune (NEI) network is proposed and further studied, the role of NEI network in realizing overall functional regulation with cytokines, hormones and neurotransmitters as information molecules has been widely verified and recognized. This paper symmetrically reviewed the pathogenesis of chloasma and the progress of the regulatory effect of TCM, and proposed the possible local efficacy of TCM for external use in treating chloasma by regulating surface NEI network. This is worth further study and exploration in the expectation of providing new ideas for the treatment of chloasma and the studies on the mechanisms of action of TCM for external use.
摘要
With a clear efficacy in external treatment of diseases, traditional Chinese medicine(TCM) has been widely applied in surgery, in acute, pediatric, gynecological, internal medicine and other departments. Its advantages include easy use, direct access to lesions, and prevent of the first-pass effect of the liver. However, its mechanism of action is still unclear, which impacts its clinical promotion. This article makes analysis and summary on the clinical application of TCM in external treatment of diseases, the characteristics of commonly used TCM in treatment of diseases, and the relationship of the common externally treated diseases and the "neurological-endocrine-immune network". The findings showed that TCM for external treatment were widely used, with exact curative effects; the pathogenesis of commonly used TCM for externally treating diseases is closely related to the "neuro-endocrine-immune network". Moreover, the modern pharmacological effects of TCM for externally treating diseases were found to be 100%related to the "neuro-endocrine-immune network". According to the analysis of the relationship between the common diseases externally treated with TCM and the "neuro-endocrine-immune network", the pathogenesis of the treatment with TCM is closely related to the "neuro-endocrine-immune network". Therefore, we believe that the "neuro-endocrine-immune network" system is probably one of the main mechanisms of action of TCMs for externally treating diseases. The verification of this mechanism requires the joint efforts of various departments in conducting clinical or experimental verification in the future, so as to provide a reference for clarifying the mechanism of TCM for external use, and basis for the promotion and application of TCM for external use.
摘要
With the rapid rise of modern drug-derived diseases, the external treatment has received extensive attention at home and abroad, due to its small adverse reactions, convenient application and accurate efficacy.At present, although there are many clinical applications of Chinese medicine external treatment, there are few unified norms and strong arbitrariness in related external treatment techniques, for example, external methods, dosage forms, means, dosage, time, etc.As a result, the development of Chinese medicine external treatment is slow and chaotic, and it can not serve the clinic well.It also hinders the development and expansion of external treatment techniques.This paper discusses the current status of external treatment techniques, and clarifies the development trend of Chinese medicine external treatment, in order to pointing out the direction for the development of Chinese medicine external treatment, it will promote the standardization of Chinese medicine external treatment techniques, and it will be better servicing the clinical practice.
摘要
The external treatment of traditional Chinese medicine(TCM) is the earliest known treatment method for diseases. It originated in pre-Qin dynasty, grew up in Han and Tang dynasties, innovated in Song and Yuan dynasties, and developed in Ming and Qing dynasties. It has made outstanding contributions to the human health.With the rapid rise of modern drug-derived diseases, the external treatment of drugs has attracted wide attention at home and abroad due to its small adverse reactions, convenient application and accurate curative effect. With the increasing of TCM for external use drugs, dosage form, method, the clinical application of TCM has been expanding unceasingly, it has been widely applied to the pediatric, gynecological, internal medicine, oncology, however, there has not many specifications for amount, usage, time, and course of treatment, which are more arbitrary. Topical use of TCM can play a direct role in the treatment of local lesions. The external use of TCM is mainly explained by "the principle of external treatment is the principle of internal treatment", and the internal use function can only be explained from the theoretical part of TCM on its external treatment characteristics, and most can not well guide the corresponding clinical application of TCM. There are few reports on the mechanism of external use of TCM, and most of them are from theory to theory, lacking the confirmation and support of modern studies. There are also related reports on transdermal absorption of scattered TCM for external use. However, most of the external use of TCM are crude preparations such as pulverising, decocting in water and alcohol extraction, and its more random which the dose, dosage type, course of treatment, external use methods, coupled with its complex ingredients and low content, it is difficult to explain the mechanism of external use simply from transdermal absorption, nor does it meet the facts of clinical application of TCM. The mechanism of external use is not clear, and restricted the development of TCM for external use. This article through the extensive experimental research, literature research and database research, and proposed that TCM for external use through adjustment of neural-endocrine-immune network disorders, through local micro effect, micro stimulation, micro absorption, that's the "three fine tuning balances", and exert external use curative effect, so as to achieve the purpose of treating diseases.
