[Screening of bioactive components endowing hawthorn with turbidity-eliminating and lipid-lowering functions and development of quality control method of hawthorn].

Hawthorn has the efficacy of eliminating turbidity and lowering the blood lipid level, and it is used for treating hyperlipidemia in clinic. However, the bioactive components of hawthorn are still unclear. In this study, the spectrum-effect relationship was employed to screen the bioactive components of hawthorn in the treatment of hyperlipidemia, and then the bioactive components screened out were verified in vivo. Furthermore, the quality control method for hawthorn was developed based on liquid chromatography-mass spectrometry(LC-MS). The hyperlipidemia model of rats was built, and different polar fractions of hawthorn extracts and their combinations were administrated by gavage. The effects of different hawthorn extract fractions on the total cholesterol(TC), triglycerides(TG), and low-density lipoprotein-cholesterol(LDL-C) in the serum of model rats were studied. The orthogonal projections to latent structures(OPLS) algorithm was used to establish the spectrum-effect relationship model between the 24 chemical components of hawthorn and the pharmacodynamic indexes, and the bioactive components were screened out and verified in vivo. Finally, 10 chemical components of hawthorn, including citric acid and quinic acid, were selected to establish the method for evaluating hawthorn quality based on LC-MS. The results showed that different polar fractions of hawthorn extracts and their combinations regulated the TG, TC, and LDL-C levels in the serum of the model rats. The bioactive components of hawthorn screened by the OPLS model were vitexin-4″-O-glucoside, vitexin-2″-O-rhamnoside, rutin, citric acid, malic acid, and quinic acid. The 10 chemical components of hawthorn, i.e., citric acid, quinic acid, rutin, gallic acid, vitexin-4″-O-glucoside, vitexin-2″-O-rhamnoside, malic acid, vanillic acid, neochlorogenic acid, and fumaric acid were determined, with the average content of 38, 11, 0.018, 0.009 5, 0.037, 0.017, 8.1, 0.009 5, 0.073, and 0.98 mg·g~(-1), respectively. This study provided a scientific basis for elucidating the material basis of hawthorn in treating hyperlipidemia and developed a content determination method for evaluating the quality of hawthorn.

Chinese expert consensus on the diagnosis and treatment of chronic cough after lung surgery / 中国胸心血管外科临床杂志

@# In recent years, the number of lung surgeries has increased year by year, and the number of patients with postoperative cough has also increased gradually. Chronic cough after lung surgery seriously affects patients' quality of life and surgical outcome, and has become one of the clinical problems that clinicians need to solve. However, there is currently no guideline or consensus for the treatment of chronic cough after lung surgery in China, and there is no standardized treatment method. Therefore, we searched databases such as PubMed, Web of Science, CNKI, and Wanfang databases ect. from 2000 to 2023 to collected relevant literatures and research data, and produced the first expert consensus on chronic cough after lung surgery in China by Delphi method. We gave 11 recommendations from five perspectives including timing of chronic cough treatment, risk factors (surgical method, lymph node dissection method, anesthesia method), prevention methods (preoperative, intraoperative, postoperative), and treatment methods (etiological treatment, cough suppressive drug treatment, traditional Chinese medicine treatment, and postoperative physical therapy). We hope that this consensus can improve the standardization and effectiveness of chronic cough treatment after lung surgery, provide reference for clinical doctors, and ultimately improve the quality of life of patients with chronic cough after lung surgery.

Identifying the active ingredients of carbonized Typhae Pollen by spectrum-effect relationship combined with MBPLS, PLS, and SVM algorithms.

Typhae Pollen (TP) and its carbonized product (carbonized Typhae Pollen, CTP), as cut-and-dried herbal drugs, have been widely used in the form of slices in clinical settings. However, the two drugs exhibit a great difference in terms of their clinical efficacy, for TP boasts an effect of removing blood stasis and promoting blood circulation, while CTP typically presents a hemostatic function. Since the active ingredients of CTP, so far, still remain unclear, this study aimed at identifying the active ingredients of CTP by spectrum-effect relationship approach coupled with multi-block partial least squares (MBPLS), partial least squares (PLS), and support vector machine (SVM) algorithms. In this study, the chemical profiles of a series of CTP samples which were stir-fried for different duration (denoted as CTP0∼CTP9) were firstly characterized by UHPLC-QE-Orbitrap MS. Then the hemostatic effect of the CTP samples was evaluated from the perspective of multiple parameters-APTT, PT, TT, FIB, TXB2, 6-keto-PGF1α, PAI-1 and t-PA-using established rat models with functional uterine bleeding. Subsequently, MBPLS, PLS and SVM were combined to perform spectrum-effect relationship analysis to identify the active ingredients of CTP, followed by an in vitro hemostatic bioactivity test for verification. As a result, a total of 77 chemical ingredients were preliminarily identified from the CTP samples, and the variations occurred in these ingredients were also analyzed during the carbonizing process. The study revealed that all the CTP samples, to a varying degree, showed a hemostatic effect, among which CTP6 and CTP7 were superior to the others in terms of the hemostatic effect. The block importance in the projection (BIP) indexes of MBPLS model indicated that flavonoids and organic acids made more contributions to the hemostatic effect of CTP in comparison to other ingredients. Consequently, 9 bioactive ingredients, including quercetin-3-O-glucoside, kaempferol-3-O-rutinoside, quercetin, kaempferol, isorhamnetin, 2-methylenebutanedioic acid, pentanedioic acid, benzoic acid and 3-hydroxybenzoic acid, were further identified as the potential active ingredients based on PLS and SVM models as well as the in vitro verification. This study successfully revealed the bioactive ingredients of CTP associated with its hemostatic effect, and also provided a scientific basis for further understanding the mechanism of TP processing. In addition, it proposed a novel path to identify the active ingredients for Chinese herbal medicines.

Sodium butyrate ameliorates diabetic retinopathy in mice via the regulation of gut microbiota and related short-chain fatty acids.

BACKGROUND: Diabetic retinopathy (DR) development is associated with disturbances in the gut microbiota and related metabolites. Butyric acid is one of the short-chain fatty acids (SCFAs), which has been found to possess a potential antidiabetic effect. However, whether butyrate has a role in DR remains elusive. This study aimed to investigate the effect and mechanism of sodium butyrate supplementation on DR. METHODS: C57BL/6J mice were divided into three groups: Control group, diabetic group, and diabetic with butyrate supplementation group. Type 1 diabetic mouse model was induced by streptozotocin. Sodium butyrate was administered by gavage to the experimental group daily for 12 weeks. Optic coherence tomography, hematoxylin-eosin, and immunostaining of whole-mount retina were used to value the changes in retinal structure. Electroretinography was performed to assess the retinal visual function. The tight junction proteins in intestinal tissue were evaluated using immunohistochemistry. 16S rRNA sequencing and LC-MS/MS were performed to determine the alteration and correlation of the gut microbiota and systemic SCFAs. RESULTS: Butyrate decreased blood glucose, food, and water consumption. Meanwhile, it alleviated retinal thinning and activated microglial cells but improved electroretinography visual function. Additionally, butyrate effectively enhanced the expression of ZO-1 and Occludin proteins in the small intestine. Crucially, only butyric acid, 4-methylvaleric acid, and caproic acid were significantly decreased in the plasma of diabetic mice and improved after butyrate supplementation. The deeper correlation analysis revealed nine genera strongly positively or negatively correlated with the above three SCFAs. Of note, all three positively correlated genera, including norank_f_Muribaculaceae, Ileibacterium, and Dubosiella, were significantly decreased in the diabetic mice with or without butyrate treatment. Interestingly, among the six negatively correlated genera, Escherichia-Shigella and Enterococcus were increased, while Lactobacillus, Bifidobacterium, Lachnospiraceae_NK4A136_group, and unclassified_f_Lachnospiraceae were decreased after butyrate supplementation. CONCLUSION: Together, these findings demonstrate the microbiota regulating and diabetic therapeutic effects of butyrate, which can be used as a potential food supplement alternative to DR medicine.

This study was aimed at identifying the bioactive components of the crude and stir-baked hawthorn for invigorating spleen and promoting digestion, respectively, to clarify the processing mechanism of hawthorn by applying the partial least squares(PLS) algorithm to build the spectrum-effect relationship model. Firstly, different polar fractions of crude and stir-baked hawthorn aqueous extracts and combinations of different fractions were prepared, respectively. Then, the contents of 24 chemical components were determined by ultra-high performance liquid chromatography-mass spectrometry. The effects of different polar fractions of crude hawthorn and stir-baked hawthorn aqueous extracts and combinations of different fractions were evaluated by measuring the gastric emptying rate and small intestinal propulsion rate. Finally, the PLS algorithm was used to establish the spectrum-effect relationship model. The results showed that there were significant differences in the contents of 24 chemical components for different polar fractions of crude and stir-baked hawthorn aqueous extracts and combinations of different fractions, and the gastric emptying rate and small intestinal propulsion rate of model rats were improved by administration of different polar fractions of crude and stir-baked hawthorn aqueous extracts and combinations of different fractions. The bioactive components of crude hawthorn identified by PLS models were vitexin-4″-O-glucoside, vitexin-2″-O-rhamnoside, neochlorogenic acid, rutin, gallic acid, vanillic acid, citric acid, malic acid, quinic acid and fumaric acid, while neochlorogenic acid, cryptochlorogenic acid, rutin, gallic acid, vanillic acid, citric acid, quinic acid and fumaric acid were the bioactive components of stir-baked hawthorn. This study provided data support and scientific basis for identifying the bioactive components of crude and stir-baked hawthorn, and clarifying the processing mechanism of hawthorn.

The specificity of body surface temperature of relevant back-shu points in patients with chronic persistent asthma based on infrared thermal imaging technology / 中国针灸

OBJECTIVE@#To detect the body surface temperature of the relevant back-shu points in patients with chronic persistent asthma by infrared thermal imaging technology, and observe the specific changes of the body surface temperature of the relevant back-shu points under the condition of lung disease.@*METHODS@#Forty-five patients with chronic persistent asthma (observation group) and 45 healthy subjects (control group) were selected. The body surface temperature of bilateral Feishu (BL 13), Geshu (BL 17), Pishu (BL 20) and Shenshu (BL 23) were measured by BK-MT02A medical infrared thermography.@*RESULTS@#The body surface temperature of bilateral Feishu (BL 13), Geshu (BL 17), Pishu (BL 20) and Shenshu (BL 23) in the observation group was higher than that in the control group (P<0.01, P<0.05). The body surface temperature of bilateral Feishu (BL 13) and Geshu (BL 17) was higher than that of ipsilateral Pishu (BL 20) and Shenshu (BL 23) in the two groups (P<0.01, P<0.05). There was no statistically significant difference in body surface temperature between ipsilateral Feishu (BL 13) and Geshu (BL 17), between ipsilateral Pishu (BL 20) and Shenshu (BL 23) (P>0.05).@*CONCLUSION@#The pathological increase of body surface temperature of Feishu (BL 13), Geshu (BL 17), Pishu (BL 20) and Shenshu (BL 23) in patients with chronic persistent asthma indicates that above acupoints have specificity in reflecting lung diseases. The Feishu (BL 13) and Geshu (BL 17), which have significantly increased body surface temperature, not only provide objective basis for the pathological pathogenesis of "deficiency in origin and excess in symptom" in patients with chronic persistent asthma, but also reflect the different expressions of different acupoints on the same meridian for the lung diseases.

Difference of lipid-lowering efficacy of "Xinjianqu" before and after fermentation and its mechanism based on LKB1-AMPK pathway and 16S rDNA sequencing technology / 中国中药杂志

On the basis of establishing the prescription of Xinjianqu and clarifying the increase of the lipid-lowering active ingredients of Xinjianqu by fermentation, this paper further compared the differences in the lipid-lowering effects of Xinjianqu before and after fermentation, and studied the mechanism of Xinjianqu in the treatment of hyperlipidemia. Seventy SD rats were randomly divided into seven groups, including normal group, model group, positive drug simvastatin group(0.02 g·kg~(-1)), and low-dose and high-dose Xinjianqu groups before and after fermentation(1.6 g·kg~(-1) and 8 g·kg~(-1)), with ten rats in each group. Rats in each group were given high-fat diet continuously for six weeks to establish the model of hyperlipidemia(HLP). After successful modeling, the rats were given high-fat diet and gavaged by the corresponding drugs for six weeks, once a day, to compare the effects of Xinjianqu on the body mass, liver coefficient, and small intestine propulsion rate of rats with HLP before and after fermentation. The effects of Xinjianqu before and after fermentation on total cholesterol(TC), triacylglyceride(TG), high-density lipoprotein cholesterol(HDL-C), low-density lipoprotein cholesterol(LDL-C), alanine aminotransferase(ALT), aspartate aminotransferase(AST), blood urea nitrogen(BUN), creatinine(Cr), motilin(MTL), gastrin(GAS), and the Na~+-K~+-ATPase levels were determined by enzyme-linked immunosorbent assay(ELISA). The effects of Xinjianqu on liver morphology of rats with HLP were investigated by hematoxylin-eosin(HE) staining and oil red O fat staining. The effects of Xinjianqu on the protein expression of adenosine 5'-monophosphate(AMP)-activated protein kinase(AMPK), phosphorylated AMPK(p-AMPK), liver kinase B1(LKB1), and 3-hydroxy-3-methylglutarate monoacyl coenzyme A reductase(HMGCR) in liver tissues were investigated by immunohistochemistry. The effects of Xinjianqu on the regulation of intestinal flora structure of rats with HLP were studied based on 16S rDNA high-throughput sequencing technology. The results showed that compared with those in the normal group, rats in the model group had significantly higher body mass and liver coefficient(P<0.01), significantly lower small intestine propulsion rate(P<0.01), significantly higher serum levels of TC, TG, LDL-C, ALT, AST, BUN, Cr, and AQP2(P<0.01), and significantly lower serum levels of HDL-C, MTL, GAS, Na~+-K~+-ATP levels(P<0.01). The protein expression of AMPK, p-AMPK, and LKB1 in the livers of rats in the model group was significantly decreased(P<0.01), and that of HMGCR was significantly increased(P<0.01). In addition, the observed＿otus, Shannon, and Chao1 indices were significantly decreased(P<0.05 or P<0.01) in rat fecal flora in the model group. Besides, in the model group, the relative abundance of Firmicutes was reduced, while that of Verrucomicrobia and Proteobacteria was increased, and the relative abundance of beneficial genera such as Ligilactobacillus and Lachnospiraceae＿NK4A136＿group was reduced. Compared with the model group, all Xinjianqu groups regulated the body mass, liver coefficient, and small intestine index of rats with HLP(P<0.05 or P<0.01), reduced the serum levels of TC, TG, LDL-C, ALT, AST, BUN, Cr, and AQP2, increased the serum levels of HDL-C, MTL, GAS, and Na~+-K~+-ATP, improved the liver morphology, and increased the protein expression gray value of AMPK, p-AMPK, and LKB1 in the liver of rats with HLP and decreased that of LKB1. Xinjianqu groups could regulate the intestinal flora structure of rats with HLP, increased observed＿otus, Shannon, Chao1 indices, and increased the relative abundance of Firmicutes, Ligilactobacillus(genus), Lachnospiraceae＿NK4A136＿group(genus). Besides, the high-dose Xinjianqu-fermented group had significant effects on body mass, liver coefficient, small intestine propulsion rate, and serum index levels of rats with HLP(P<0.01), and the effects were better than those of Xinjianqu groups before fermentation. The above results show that Xinjianqu can improve the blood lipid level, liver and kidney function, and gastrointestinal motility of rats with HLP, and the improvement effect of Xinjianqu on hyperlipidemia is significantly enhanced by fermentation. The mechanism may be related to AMPK, p-AMPK, LKB1, and HMGCR protein in the LKB1-AMPK pathway and the regulation of intestinal flora structure.

Chinese medicinal resources are the cornerstone of the sustainable development of traditional Chinese medicine industry. However, due to the fecundity of species, over-exploitation, and limitations of artificial cultivation, some medicinal plants are depleted and even endangered. Tissue culture, a breakthrough technology in the breeding of traditional Chinese medicinal materials, is not limited by time and space, and can allow the production on an annual basis, which plays an important role in the protection of Chinese medicinal resources. The present study reviewed the applications of tissue culture of medicinal plants in the field of Chinese medicinal resources, including rapid propagation of medicinal plant seedlings, breeding of novel high-yield and high-quality cultivars, construction of a genetic transformation system, and production of secondary metabolites. Meanwhile, the current challenges and suggestions for the future development of this field were also proposed.

Chinese multidisciplinary expert consensus on the management of adverse drug reactions associated with savolitinib / 中华肿瘤杂志

MET gene is a proto-oncogene, which encodes MET protein with tyrosine kinase activity. After binding to its ligand, hepatocyte growth factor, MET protein can induce MET dimerization and activate downstream signaling pathways, which plays a crucial role in tumor formation and metastasis. Savolitinib, as a specific tyrosine kinase inhibitor (TKI) targeting MET, selectively inhibits the phosphorylation of MET kinase with a significant inhibitory effect on tumors with MET abnormalities. Based on its significant efficacy shown in the registration studies, savolitinib was approved for marketing in China on June 22, 2021 for the treatment of advanced non-small cell lung cancer with MET 14 exon skipping mutations. In addition, many studies have shown that MET TKIs are equally effective in patients with advanced solid tumors with MET gene amplification or MET protein overexpression, and relevant registration clinical studies are ongoing. The most common adverse reactions during treatment with savolitinib include nausea, vomiting, peripheral edema, pyrexia, and hepatotoxicity. Based on two rounds of extensive nationwide investigations to guide clinicians, the consensus is compiled to use savolitinib rationally, prevent and treat various adverse reactions scientifically, and improve the clinical benefits and quality of life of patients. This consensus was prepared under the guidance of multidisciplinary experts, especially including the whole-process participation and valuable suggestions of experts in Traditional Chinese Medicine, thus reflecting the clinical treatment concept of integrated Chinese and western medicines.

DUS testing guidelines for new varieties of Chinese medicinal plants / 中国中药杂志

A rich diversity of wild medicinal plant resources is distributed in China, but the breeding of new plant varieties of Chinese medicinal plants started late and the breeding level is relatively weak. Chinese medicinal plant resources are the foundation for new varieties breeding, and the plant variety rights(PVP) are of great significance for the protection and development of germplasm resources. However, most Chinese medicinal plants do not have a distinctness, uniformity, and stability(DUS) testing guideline. The Ministry of Agriculture and Rural Affairs has put 191 plant species(genera) on protection lists, of which only 30 are medicinal species(genera). At the same time, only 29 of 293 species(genera) plants in the Protection List of New Plant Varieties of the People's Republic of China(Forest and Grass) belong to Chinese medicinal plants. The number of PVP applications and authorization of Chinese medicinal plants is rare, and the composition of variety is unreasonable. Up to now, 29 species(genera) of DUS test guidelines for Chinese medicinal plants have been developed. Some basic problems in the breeding of new varieties of Chinese medicinal plants have appeared, such as the small number of new varieties and insufficient utilization of Chinese medicinal plant resources. This paper reviewed the current situation of breeding of new varieties of Chinese medicinal plants and the research progress of DUS test guidelines in China and discussed the application of biotechnology in the field of Chinese medicinal plant breeding and the existing problems in DUS testing. This paper guides the further application of DUS to protect and utilize the germplasm resources of Chinese medicinal plants.

Male Infertility Responding Specifically to Traditional Chinese Medicine / 中国实验方剂学杂志

In recent years，with the change in lifestyle and social environment and the increase in pressure in both life and work，male fertility has decreased significantly in China，and the incidence of male infertility has increased year by year，which has brought great challenges to andrologists. Traditional Chinese medicine （TCM） has a definite curative effect in the treatment of male infertility and is widely applied in clinical practice. In order to clarify the role of TCM in different types and each stage of male infertility，the China Association of Chinese Medicine （CACM） invited outstanding young andrologists in the clinic of TCM and western medicine to discuss topics such as idiopathic oligospermia and teratospermia，abnormal semen liquefaction，varicocele，immune infertility，improving success ratio of assisted reproductive technology，and ameliorating depression or anxiety. They conducted in-depth discussions on the advantages，characteristics，disadvantages，diseases responding specifically，and advantageous aspects of TCM treatment. The causes of male infertility and related links of treatment were summarized. Due to the unclear etiology and complex pathogenesis of male infertility，western medicine cannot achieve a good curative effect，while TCM，taking the holistic view as the core，specializes in improving functional diseases and can correspond to multiple targets and factors，with comprehensive treatments such as internal treatment and external treatment. This study summarized the advantageous diseases and advantageous stages of TCM treatment alone and integrated TCM and western medicine treatment and put forward suggestions for the treatment of the diseases by TCM and western medicine in order to promote the therapeutic effects and advantages of TCM among andrologists，increase mutual learning and communication between TCM and western physicians，provide patients with excellent and personalized treatment plans in clinical practice，and improve the curative effect of male infertility and fertility of males in China.

Contributions and strategies of eco-agriculture of Chinese medicine services for carbon dioxide peaking and carbon neutrality / 中国中药杂志

Carbon dioxide peaking and carbon neutrality have become hot issues of political and economic activities in China and abroad. The structure and development of various industries in China will be profoundly affected in the process of accomplishing "Dual Carbon" goals. Eco-agriculture of Chinese medicine(EACM) highlights the balance and sustainable development of the ecosystem while producing high-quality medicinal materials. With chemically synthesized fertilizers, pesticides, and growth regulators prohibited, EACM emphasizes the recycling of agricultural and sideline products and the reduction of waste output, which results in the minimal negative impact on the ecological environment. Therefore, it is typical agriculture with low-carbon sources and high-carbon sinks. This study reviewed the mechanism and potential of EACM in carbon dioxide peaking and carbon neutrality, analyzed the specific ways of EACM in reducing carbon sources and increasing carbon sinks based on the typical ecological planting pattern, and proposed the point of view to strengthen EACM as well as the "Dual Carbon" theory and research methods, so as to direct low-carbon and efficient deve-lopment. Furthermore, this study advocated to comprehensively promote the transformation of Chinese medicine production from chemical agriculture to eco-agriculture to improve the comprehensive benefits of contribution rate of carbon neutrality, explore and establish carbon sink compensation mechanism to ensure the sustainable and healthy development of EACM, and strengthen the training of EACM and "Dual Carbon" theory and technologies to continuously improve the capacity of EACM in sustainable development. This study is expected to provide a reference for the development of ecological functions in EACM and the development of economic functions through ecological functions.

Components of drugs in acupoint sticking therapy and its mechanism of intervention on bronchial asthma based on UPLC-Q-TOF-MS combined with network pharmacology and experimental verification / 中国中药杂志

UPLC-Q-TOF-MS combined with network pharmacology and experimental verification was used to explore the mechanism of acupoint sticking therapy(AST) in the intervention of bronchial asthma(BA). The chemical components of Sinapis Semen, Cory-dalis Rhizoma, Kansui Radix, Asari Radix et Rhizoma, and Zingiberis Rhizoma Recens were retrieved from TCMSP as self-built database. The active components in AST drugs were analyzed by UPLC-Q-TOF-MS, and the targets were screened out in TCMSP and Swiss-TargetPrediction. Targets of BA were collected from GeneCards, and the intersection of active components and targets was obtained by Venny 2.1.0. The potential targets were imported into STRING and DAVID for PPI, GO, and KEGG analyses. The asthma model induced by house dust mite(HDM) was established in mice. The mechanism of AST on asthmatic mice was explored by pulmonary function, Western blot, and flow cytometry. The results indicated that 54 active components were obtained by UPLC-Q-TOF-MS and 162 potential targets were obtained from the intersection. The first 53 targets were selected as key targets. PPI, GO, and KEGG analyses showed that AST presumedly acted on SRC, PIK3 CA, and other targets through active components such as sinoacutine, sinapic acid, dihydrocapsaicin, and 6-gingerol and regulated PI3 K-AKT, ErbB, chemokine, sphingolipid, and other signaling pathways to intervene in the pathological mechanism of BA. AST can improve lung function, down-regulate the expression of PI3 K and p-AKT proteins in lung tissues, enhance the expression of PETN protein, and reduce the level of type Ⅱ innate immune cells(ILC2 s) in lung tissues of asthmatic mice. In conclusion, AST may inhibit ILC2 s by down-regulating the PI3 K-AKT pathway to relieve asthmatic airway inflammation and reduce airway hyperresponsiveness.

Mechanism of Prunellae Spica Against Breast Diseases： A Review / 中国实验方剂学杂志

Prunellae Spica is the dry ear of the labiaceae plant Prunella vulgaris， which is a traditional medicine and food plant with many functions. Prunellae Spica can clear liver-fire， improve eyesight， disperse knot detumescence. It owns hot and bitter flavors and cold property. It goes to the liver， gallbladder meridian， and is a kind of commonly-used antifebric. Prunellae Spica has been used in the treatment of mammary gland diseases since ancient times.The mammary abscess， mammary nodules， mammary carcinoma of traditional Chinese medicine all belong to breast disease， and the liver meridian is most closely related to these diseases. With the development of social life， breast disease has gradually become the most primary health problem for women. Modern pharmacological studies show that Prunellae Spica contains terpenoids， phenolic acids， flavonoids and other biological active components， which have anti-inflammatory， antibacterial， hormone regulation， anti-tumor and other effects. Prunellae Spica inhibits the p38 mitogen-activated protein kinase （p38 MAPK）/nuclear factor kappa-B （NF-κB） pathway to play an anti-mastitis role， interferes with the effects of estrogen receptors or regulates lipid levels to treat breast hyperplasia， and treats breast cancer through promoting the apoptosis of breast cancer cells， inhibiting the migration of breast cancer cells， regulating the division of breast cancer cells and other ways. While referring to the relevant literature， it was found that Prunellae Spica often exerted pharmacological effects through multi-channels and multi-target regulation， but most of the studies did not specify the specific target of its effect， which needs further study. In this review， the effects and mechanisms of Prunellae Spica in the treatment of various breast diseases were summarized， so as to provide a reference for further research on the wider clinical therapeutic effects of Prunella subtilis and its therapeutic effects on breast diseases.

Clinical Research on Treatment of Benign Prostatic Hyperplasia with Traditional Chinese Medicine： A Review / 中国实验方剂学杂志

Benign prostatic hyperplasia （BPH）， a common disease in urology and andrology， is mainly manifested as enlarged prostate glands， bladder outlet obstruction， and lower urinary tract symptoms（LUTS）， which seriously affects the quality of life of middle-aged and elderly men. This disease falls into the categories of "retention of urine" and "prostatic hypertrophy" in traditional Chinese medicine （TCM）. In recent years，many doctors have put forward their understandings of BPH based on academic classics and their clinical experience. Clinical research on the treatment of BPH with TCM has become increasingly abundant. The basic pathogenesis of BPH lies in the disturbance of Qi transformation in the bladder and poor blood circulation due to kidney Qi deficiency in the aged. The disease is located in the kidney and the bladder and is related to the dysfunction of the lung and the kidney. It is basically characterized by deficiency in origin and excess in superficiality. A large number of clinical research reports have proved that TCM is efficient in alleviating the clinical symptoms of BPH patients， improving their quality of life， reducing the volume of the prostate， and decreasing postoperative complications. In addition， the external treatment methods of TCM， such as acupuncture therapy， moxibustion， hot water bathing， acupoint application， anal suppository， and enema therapy， are also widely used in clinical practice， demonstrating the diverse ways of TCM in treating BPH. TCM and western medicine complement each other's advantages in the treatment of BPH， thus enhancing the clinical efficacy and reducing the occurrence of long-term complications. This study reviewed the etiology， pathogenesis， and treatment progress of BPH with TCM in recent years， and summarized the current research status. From three aspects of producing high-quality clinical research， standardizing the clinical diagnosis and treatment of TCM， and combining cutting-edge research to explore the mechanism of TCM， it provided suggestions for clinical research on the treatment of BPH with TCM to promote the development and application of TCM in the treatment of this disease.

Tissue-Specific Gamma-Flicker Light Noninvasively Ameliorates Retinal Aging.

Aging is a risk factor for multiple retinal degeneration diseases. Entraining brain gamma oscillations with gamma-flicker light (γFL) has been confirmed to coordinate pathological changes in several Alzheimer's disease mouse models and aged mice. However, the direct effect of γFL on retinal aging remains unknown. We assessed retinal senescence-associated beta-galactosidase (ß-gal) and autofluorescence in 20-month-old mice and found reduced ß-gal-positive cells in the inner retina and diminished lipofuscin accumulation around retinal vessels after 6 days of γFL. In immunofluorescence, γFL was further demonstrated to ameliorate aging-related retinal changes, including a decline in microtubule-associated protein 1 light chain 3 beta expression, an increase in complement C3 activity, and an imbalance between the anti-oxidant factor catalase and pro-oxidant factor carboxymethyl lysine. Moreover, we found that γFL can increase the expression of activating transcription factor 4 (ATF4) in the inner retina, while revealing a decrease of ATF4 expression in the inner retina and positive expression in the outer segment of photoreceptor and RPE layer for aged mice. Western blotting was then used to confirm the immunofluorescence results. After mRNA sequencing (NCBI Sequence Read Archive database: PRJNA748184), we found several main mechanistic clues, including mitochondrial function and chaperone-mediated protein folding. Furthermore, we extended γFL to aged Apoe-/- mice and showed that 1-m γFL treatment even improved the structures of retinal-pigment-epithelium basal infolding and Bruch's membrane. Overall, γFL can orchestrate various pathological characteristics of retinal aging in mice and might be a noninvasive, convenient, and tissue-specific therapeutic strategy for retinal aging.

A multifunctional nanodiamond-based nanoplatform for the enhanced mild-temperature photothermal/chemo combination therapy of triple negative breast cancer via an autophagy regulation strategy.

Owing to its aggressive biological behavior, the lack of specific targets, and the strong therapeutic resistance of triple negative breast cancer (TNBC), current therapeutic strategies are still limited. The combination of multiple treatments has been confirmed as a promising strategy for TNBC therapy. However, the efficacy of combination therapy can be restricted due to increasing therapeutic resistance to various treatments. Herein, we constructed a nanodiamond (ND)-based nanoplatform for augmented mild-temperature photothermal/chemo combination therapy against TNBC, weakening the therapeutic resistance via autophagy inhibition enabled by the NDs. A layer-by-layer self-assembly approach was utilized to construct the ND-based nanoplatform. First, the NDs were modified with protamine sulphate (PS). Meanwhile, the photosensitizer indocyanine green (ICG) and the HSP70 small molecule inhibitor apoptozole (APZ) could be synchronously incorporated to form positively charged PS@ND (ICG + APZ). Then negatively charged hyaluronic acid (HA) was assembled onto the outer face of PS@ND (ICG + APZ) to form the NPIAs. Finally, the positively charged small molecule anti-cancer drug doxorubicin (DOX) could be adsorbed onto the surface of the NPIAs through electrostatic interactions (NPIADs). The resulting NPIADs could be triggered by NIR laser irradiation to exhibit enhanced mild-temperature photothermal therapy (PTT) effects via suppressing the expression of HSP70, and PTT combined with chemotherapy could further enhance the anti-tumor efficacy. Subsequently, the sensitivity of MDA-MB-231 cells could be significantly improved through the weakening of the thermal/drug resistance via autophagy inhibition, leading to augmented combination therapy that is efficient both in vitro and in vivo. Furthermore, the NPIADs could be used as a theranostic nanoplatform for fluorescence (FL) and photoacoustic (PA) imaging. Taken together, this study demonstrated a multifunctional ND-based nanoplatform for FL/PA imaging-guided augmented mild-temperature photothermal/chemo combination therapy via an autophagy regulation strategy against TNBC.
