As the number of patients with compromised immune function increases and fungal resistance develops, so does the risk of contracting deadly fungi in humans. Both fungi and humans are eukaryotes, so identifying unique targets for antifungal drug development is difficult. In addition, the existing antifungal drugs are limited by toxicity, drug interaction and drug resistance in practical application, which leads to the increasing incidence and fatal rate of fungal infections. Therefore, it is urgent to develop new antifungal drugs. The semi-synthetic technology using microbial fermentation products from natural sources as lead compounds has become the most used method in structural modification of antifungal drugs due to its advantages of few reaction steps and easy operation. This paper will introduce the current status of natural antifungal drugs in clinical use, as well as the latest progress in the research and development of new semi-synthetic antifungal drugs, and summarize their mechanism of action, structural modifications, advantages and disadvantages, so as to provide reference for the subsequent development of new antifungal drugs.

To summarize the clinical experience of Professor LIU Shangyi in treating pruritus vulvae. It is believed that women have the physiological characteristics of liver and kidney as the root， and their pubic area is easily attacked by wind-dampness pathogenic qi， so the core mechanism of pruritus vulvae is proposed as wind-dampness accumulation and deficiency of liver and kidney. The core treatment method is to dispel wind-dampness and nourish the liver and kidneys， and modify the Danggui Decoction （当归饮子） to form a self-prescribed Yinyang Formula （阴痒方） as the basic prescription to treat pruritus vulvaen.

BACKGROUND:The specific mechanism of Gushukang,as a Chinese traditional patent medicine for the treatment of postmenopausal osteoporosis of kidney deficiency and blood stasis,needs further studies. OBJECTIVE:To investigate the effect of Gushukang on serum sex hormones,bone microstructure and estrogen receptor in postmenopausal osteoporosis. METHODS:Firstly,network pharmacological analysis was performed.The active ingredients and action targets of Gushukang and the targets of postmenopausal osteoporosis were obtained respectively.Cytoscape was used to construct the active ingredient-target network.STRING database and Cytoscape were used for protein-protein interaction analysis and screening of core targets.DAVID database was used for Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses of intersection targets.Then the ovariectomized Sprague-Dawley rats were used in the animal experiment.Gushukang was administered by gavage for 3 months.The serum estrogen level was detected by ELISA,the bone microstructure was detected by microCT,and the protein expression of estrogen receptor α and estrogen receptor β in bone tiusse was detected by western blot. RESULTS AND CONCLUSION:The network pharmacological research results identified 132 active ingredients and 150 targets of Gushukang and 1155 targets of postmenopausal osteoporosis.After intersections with 1155 postmenopausal osteoporosis targets,87 targets of active ingredients of Gushukang against postmenopausal osteoporosis were obtained.By constructing the active ingredient-target network,it was found that the active ingredients at the core were quercetin,kaempferol,luteolin,naringin and isorhamnetin,and the targets at the core were NCOA2,ESR2,AR,F2,ESR1 and PTGS1.The final targets obtained after the protein-protein interaction analysis and screening included MAPK8,ESR1,JUN,R3C1,RELA and FOS,of which ESR1 was the common core target obtained from the two analyses.KEGG enrichment analysis showed estrogen,tumor necrosis factor,apoptosis and other signaling pathways.Therefore,animal experiments focused on the effect of Gushukang on different subtypes of estrogen receptors in the estrogen signaling pathway.The results showed that in the Gushukang group,bone microstructure was significantly improved,serum estrogen level had no significant change,but the protein expression of estrogen receptor α and β in bone tissue was significantly increased.All the findings indicate that the mechanism of Gushukang in the treatment of postmenopausal osteoporosis may be related to its hormone-like effect and the enhancement of estrogen receptor expression.

ObjectiveTo investigate the impact of early intervention with Yishen Huazhuo prescription （YHP） on the learning and memory of accelerated aging model mice， as well as its underlying mechanism. MethodForty-eight 3-month-old male SAMP8 mice were randomly assigned into four groups， including the model group， low-dose YHP group， high-dose YHP group， and donepezil group. Additionally， 24 SAMR1 mice of the same age were divided into a control group and a YHP treatment control group， each consisting of 12 mice. The YHP groups received YHP at doses of 6.24 g·kg^-1 and 12.48 g·kg^-1， while the donepezil group was treated with donepezil at a dose of 0.65 mg·kg^-1. The model group and control groups were given physiological saline. The mice were gavaged once daily for a duration of four weeks. Spatial learning and memory abilities of mice were assessed using the Morris water maze test. Immunofluorescence staining was employed to evaluate neuronal density as well as expression levels of M1 microglial （MG） polarization marker inducible nitric oxide synthase （iNOS） and M2 MG polarization marker arginase-1 （Arg-1） in the hippocampus region. Enzyme-linked immunosorbent assay （ELISA） was used to measure serum levels of pro-inflammatory factor interleukin 1β （IL-1β） and anti-inflammatory factor transforming growth factor-β₁ （TGF-β₁）. Furthermore， Western blot analysis was conducted to determine expressions of amyloid β peptide1-42 （Aβ_1-42） along with triggering receptor expressed on myeloid cells 2 （TREM2）/nuclear factor kappa B （NF-κB） signaling pathway-related proteins TREM2， phospho （p）-NF-κB p65， and phospho-inhibitory kappa B kinase β （IKKβ） in the hippocampus. ResultCompared with the control group， the model group exhibited a significantly prolonged escape latency （P<0.01）， a significant reduction in neuron-specific nuclear protein （NeuN） expression in the hippocampus， a significant increase in iNOS expression in MG， and a significant decrease in Arg-1 expression. The serum IL-1β content was significantly increased， while the TGF-β₁ content was significantly decreased. Additionally， there was a significant decrease in TREM2 expression in the hippocampus and significant increases in p-NF-κB p65， p-IKKβ， and Aβ_1-42 expressions （P<0.05， P<0.01）. However， no significant changes were observed in escape latency， times of crossing the platform， and hippocampal NeuN expression in the YHP treatment control group. Conversely， iNOS expression in MG as well as the hippocampal p-NF-κB p65， p-IKKβ， and Aβ_1-42 expressions were significantly decreased. Furthermore， TREM2 expression was significantly increased （P<0.05， P<0.01）. In comparison to the model group， the low-dose YHP group showed a significantly shortened escape latency and an increased number of crossing the platform （P<0.05， P<0.01）. In the high-dose YHP group， the escape latency was significantly shortened （P<0.05）. In the low-dose YHP group， high-dose YHP group， the expression of NeuN in the hippocampus was significantly increased， the expression of iNOS in MG was significantly decreased， and the expression of Arg-l was significantly increased. The serum IL-1β content was significantly decreased， while the TGF-β₁ content was significantly increased. Furthermore， the expression of TREM2 in the hippocampus was significantly increased， and the expressions of p-NF-κB p65， p-IKKβ， and Aβ_1-42 were significantly decreased （P<0.01）. ConclusionEarly YHP intervention may promote the transformation of hippocampal MG from M1 to M2 by regulating the TREM2/NF-κB signaling pathway， reduce the release of neuroinflammatory factors， protect hippocampal neurons， and reduce the deposition of Aβ_1-42， and finally delay the occurrence of learning and memory decline in SAMP8 mice.

ObjectiveTo evaluate the clinical effectiveness and safety of Bairui Granules （百蕊颗粒） in the treatment of acute pharyngitis with wind-heat syndrome. MethodsA multicenter， double-blind， double-simulation， randomised controlled trial was conducted， in which 162 patients with acute pharyngitis and wind-heat syndrome from 7 centers were recruited， and each center was divided into trial group and control group on the ratio of 2∶1. In the trial group， 108 cases were orally administered with Bairui Granules plus Reyanning Granules （热炎宁颗粒） simulant， and in the control group， 54 cases were orally administered with Reyanning Granules plus Bairui Granules simulant for 5 days， with a follow-up visit on the 6th day. Full analysis set （FAS） analysis and per protocol set （PPS） were used for analysis， respectively. The primary efficacy index was the disappearance rate of sore throat after 5-day treatment； the secondary efficacy indexes were the disappearance rate of sore throat after 3-day treatment， as well as the visual analogue score （VAS） of sore throat before treatment， every day during the treatment， and follow-up on day 6， and the traditional Chinese medicine （TCM） syndrome score was performed before treatment and at the follow-up on day 6. The effectiveness on TCM syndrome was evaluated at the follow-up on day 6， and the changes of vital signs， blood routine， urine routine， liver functions， kidney function， the adverse events before and after the treatment were recorded， and safety analysis set （SS） was analysed. Results162 patients entered the FAS and SS analyses， and 158 cases （105 cases in the trial group and 53 cases in the control group） entered the PPS analysis. FAS analysis showed that the disappearance rate of sore throat after 5-day treatment was 80.56% （87/108） in the trial group and 64.81% （35/54） in the control group， and the difference between groups was statistically significant （χ² = 5.10， P = 0.0239）. PPS analysis showed that the disappearance rate of sore throat after 5-day treatment was 80.00% （84/105） in the trial group and 64.15% （34/53） in the control group， and the difference between groups was statistically significant （χ² =4.85， P = 0.0277）. FAS and SS analyses both showed that the difference in disappearance rate of sore throat between groups on 3-day treatment was not statistically significant （P＞0.05）. Compared with those before treatment， the VAS scores of sore throat were lower in both groups during treatment on day 2， 3， 4， 5， and follow-up on day 6 （P＜0.01）， but the difference between groups at each time point was not statistically significant （P＞0.05）. TCM syndrome scores of both groups at the follow-up were lower than that before treatment， and those of the trial group were lower than those of the control group （P＜0.01）. The cure rate and effective rate of TCM syndrome of the trial group were significantly higher than those of the control group （P＜0.01）. There was no significant difference in blood routine， urine routine， liver function， kidney function between groups before and after treatment （P＞0.05）， and no serious adverse events occured in both groups. ConclusionBairui Granules showed clinical effectiveness in the treatment of acute pharyngitis of wind-heat syndrome， and it could significantly improve the clinical symptoms， accelerate the disappearance time of sore throat with good safety.

ObjectiveIt was reported that the transthyretin (TTR) has a neuroprotective effect on Alzheimer’s disease (AD), which is manifested by the ability of TTR to inhibit the pathological aggregation of amyloid beta protein (Aβ). In this work, we investigated the mechanism of the interactions between TTR and Aβ at the molecular level to reveal the neuroprotective effect of TTR on AD. MethodsProtein-protein docking was used to explore the models of interaction between different structural forms of TTR and Aβ, and molecular dynamics simulation was further applied to investigate the dynamic process of the interaction between the two. ResultsBoth TTR tetramer and monomer can interact with Aβ monomer, and the thyroxine-binding channel of TTR tetramer is the main binding site of Aβ monomer. In addition, the EF helix and EF loop of TTR tetramer were also able to bind Aβ monomer. When the TTR tetramer dissociates, the hydrophobic site of the internal TTR monomer is exposed, which has a strong affinity for Aβ monomer. For the interaction between Aβ aggregates and TTR, a higher degree of aggregation can be formed between TTR monomer and Aβ aggregates due to the β-sheet-rich property of TTR monomer and Aβ aggregates, which may therefore reduce the cytotoxicity of Aβ aggregates. ConclusionBoth TTR tetramer and monomer can inhibit Aβ aggregation by “sequestering” Aβ monomer, while TTR monomer can reduce the cytotoxicity of Aβ aggregates by forming large co-aggregation with Aβ aggregates. This work can provide an important theoretical basis for the design and discovery of anti-AD drugs based on the neuroprotective effects of TTR.

Tumor is one of the major diseases that endanger people’s health. At present, the treatments used for tumor include surgery, chemotherapy, radiotherapy and so on. Nonetheless, the traditional treatments have some disadvantages, such as insufficient treatment effect, liable to cause multidrug resistance, toxicity and side effect. Further research and exploration of tumor treatment schemes are still necessary. As the energy converter of cells, mitochondria are currently considered to be one of the most important targets for the design of new drugs for tumor, cardiovascular and neurological diseases. Nano-drug delivery carriers have the characteristics of being easily modified with active targeting groups, and it can achieve accurate targeted drug delivery to cells and organelles. This paper reviews the application of mitochondrial targeted nanoparticles in tumor diagnosis and treatment from the aspects of inhibiting tumor cell proliferation, promoting tumor cell apoptosis, inhibiting tumor recurrence and metastasis, and inducing cell autophagy.

Background Stroke patients commonly experience varying degrees of psychological distress.Previous studies have shown that the psychological distress of stroke patients is closely related to their coping styles and resourcefulness.However,the path of wisdom in coping style and psychological pain of stroke patients is still unclear.Objective To explore the path of resourcefulness between coping styles and psychological distress in stroke patients,so as to provide insights for interventions targeting psychological distress.Methods A total of 350 patients who met the diagnostic criteria for stroke according to the Diagnostic Criteria of Cerebrovascular Diseases in China(version 2019)and were admitted to the neurology departments of two tertiary grade-A hospitals in Luzhou City from January to May 2023 were selected as the research subjects.Basic information was collected using a self-designed questionnaire,and Resourcefulness Scale(RS),Medical Coping Mode Questionnaire(MCMQ)and Distress Thermometer(DT)were used for assessment.Pearson correlation analysis was conducted to examine the correlation between the scores of each scale.Model 4 of the Process 3.4.1 program was employed to analyze the path of resourcefulness between coping styles and psychological distress,and the Bootstrap method was used to test the mediation effects.Results The DT score showed a negative correlation with the confrontation and RS scores(r=-0.581,-0.716,P<0.01),and a positive correlation with the avoidance and resignation scores(r=0.432,0.758,P<0.01).The confrontation score was positively correlated with RS score(r=0.700,P<0.01),while the avoidance and resignation scores were negatively correlated with RS score(r=-0.460,-0.566,P<0.01).Resourcefulness might serve as a mediating path between confrontation,avoidance,resignation,and psychological distress,with the effect value of-0.359,0.203 and 0.183,accounting for 81.78%,62.65%and 27.07%of the path effect,respectively.Conclusion The coping styles of stroke patients can directly affect their psychological distress,and can also indirectly influence it through resourcefulness.Resourcefulness may play a mediating role between coping styles and psychological distress.
