Anti-tumor traditional Chinese medicine has a long history of clinic application, in which the star molecules have always been the hotspot of modern drug research, but they are limited by the solubility, stability, targeting, bioactivity or toxicity of the monomer components of traditional Chinese medicine anti-tumor star molecules and other pharmacokinetic problems, which hinders the traditional Chinese medicine anti-tumor star molecules for further clinical translation and application. Currently, the nanosystems prepared by supramolecular technologies such as molecular self-assembly and nanomaterial encapsulation have broader application prospects in improving the anti-tumor effect of active components of traditional Chinese medicine, which has attracted extensive attention from scholars at home and abroad. In this paper, we systematically review the research progress in preparation of supramolecular nano-systems from anti-tumor star molecule of traditional Chinese medicine, and summarize the two major categories and ten small classes of carrier-free and carrier-based supramolecular nanosystems and their research cases, and the future development direction is put forward. The purpose of this paper is to provide reference for the research and clinical transformation of using supramolecular technology to improve the clinical application of anti-tumor star molecule of traditional Chinese medicine.

AIM To investigate the ameliorative effects of Schisandrol A(Sol A)in Suhuang antitussive capsule on post-infectious cough(PIC).METHODS The in vivo mouse PIC model was established by intratracheal instillation of lipopolysaccharide(LPS)combined with cigarette smoke exposure.The mice were randomly divided into the control group,the model group,the Suhuang antitussive capsule group(14 g/kg),the montelukast sodium positive control group(3 mg/kg),and low and high dose Sol A groups(10,30 mg/kg).The in vitro PIC model was established by stimulating human bronchial epithelial cells(BEAS-2B)with LPS.The cells were divided into the control group,the model group,the Suhuang antitussive capsule group(10 μg/mL)and low and high dose Sol A groups(3,10 μmol/L).HE and Masson staining were used to detect the pathological changes of the lung and bronchial tissues.ELISA was used to detect the levels of IL-1β,IL-6,TNF-α,ROS,MDA,SOD and GSH in the lung tissues.RT-qPCR was used to detect the IL-1β,IL-6 and TNF-α mRNA expressions in BEAS-2B cells.And Western blot was applied to detect the protein expressions of p-PI3K,p-Akt,NOX4,SIRT1,p-ERK,Fibronectin,E-cadherin,Vimentin and α-SMA in mouse lung tissue and BEAS-2B cells.RESULTS Compared with the model group,the groups intervened with Sol A or Suhuang antitussive capsule displayed prolonged cough latency(P＜0.01);reduced cough frequency(P＜0.01);relieved pulmonary inflammatory cell infiltration and collagen deposition in PIC mice;decreased pulmonary levels of IL-1β,IL-6,TNF-α,ROS,MDA and protein expressions of Fibronectin,Vimentin,α-SMA,p-ERK,p-PI3K,p-Akt,and NOX4(P＜0.05,P＜0.01);increased pulmonary levels of SOD and GSH and protein expressions of E-cadherin and SIRT1(P＜0.05,P＜0.01);decreased ROS level,IL-1β,IL-6,TNF-α mRNA expressions and p-ERK,p-PI3K,p-Akt,NOX4 protein expressions in vitro(P＜0.05,P＜0.01);and increased SIRT1 protein expression in vitro as well(P＜0.01).CONCLUSION Being the main antitussive component of Suhuang antitussive capsule upon the PIC model,Sol A inhibits the inflammation via SIRT1/ERK signaling pathway and relieve the oxidative stress via PI3K/Akt/NOX4 signaling pathway.

AIM To explore the effects of praeruptorin A from Suhuang antitussive capsules on cough variant asthma(CVA).METHODS The rats were randomly divided into the normal group,the model group,the dexamethasone group(0.5 mg/kg),the Suhuang antitussive capsules group(7 g/kg)and the low,medium and high dose praeruptorin A groups(15,30 and 60 mg/kg).The rat model of CVA was established by intraperitoneal injection of sensitizer(1 mg/mL ovalbumin and 10 mg/mL aluminum hydroxide)and aerosol inhalation of 1%ovalbumin followed by the corresponding dosing of drugs by gavage initiated on the 14th day.Another 14 days later,the rats had their pathological pulmonary changes observed by HE,Masson and PAS stainings;their number of inflammatory cells in bronchoalveolar lavage fluid(BALF)detected by hematology analyzer;and their levels of IL-4,IL-5,IL-13 and MUC5AC in BALF detected by ELISA.The RAW264.7 cell inflammatory model induced by lipopolysaccharide(LPS)was treated with 4,8,16 μmol/L praeruptorin A or 0.25 mg/mL Suhuang antitussive capsules,respectively.And the cells had their NO level detected by Griess method,and their ROS expression observed using fluorescence microscopy.The detections of the pulmonary and cellular mRNA expressions of IL-6,IL-1β,COX-2,iNOS and PPAR-γ by RT-qPCR;and the protein expressions of p-P65,P65,p-IκBα,IκBα,NLRP3,caspase-1(p20)and IL-1β by Western blot were conducted in both the cells and the rats.RESULTS The in vivo result showed that praeruptorin A reduced the cough frequency(P＜0.01);prolonged the cough latency(P＜0.05,P＜0.01);reduced the number of eosinophils and neutrophils in BALF(P＜0.05,P＜0.01);decreased the levels of IL-4,IL-5,IL-13 and MUC5AC in BALF and the pulmonary mRNA expressions of IL-6,IL-1β,COX-2 and iNOS(P＜0.05,P＜0.01);and decreased the phosphorylation of P65 and IκBα protein and NLRP3,caspase-1(p20)and IL-1β protein expressions(P＜0.05,P＜0.01)as well.The in vitro result showed that praeruptorin A inhibited the release of LPS-induced NO and reduce the ROS level(P＜0.01);decreased the mRNA expressions of IL-1β,COX-2 and iNOS(P＜0.05,P＜0.01);increased PPAR-γ mRNA expression(P＜0.05),and decreased the phosphorylation of P65 and IκBα protein and the expression of NLRP3 protein(P＜0.05,P＜0.01).CONCLUSION Praeruptorin A,one of the main antitussive components of Suhuang antitussive capsules,may improve CVA because of its anti-inflammatory and antitussive role by inhibiting the activation of NF-κB signaling pathway and reducing the expression of NLRP3 inflammatory corpuscles.

OBJECTIVE: To derive the Chinese medicine (CM) syndrome classification and subgroup syndrome characteristics of ischemic stroke patients. METHODS: By extracting the CM clinical electronic medical records (EMRs) of 7,170 hospitalized patients with ischemic stroke from 2016 to 2018 at Weifang Hospital of Traditional Chinese Medicine, Shandong Province, China, a patient similarity network (PSN) was constructed based on the symptomatic phenotype of the patients. Thereafter the efficient community detection method BGLL was used to identify subgroups of patients. Finally, subgroups with a large number of cases were selected to analyze the specific manifestations of clinical symptoms and CM syndromes in each subgroup. RESULTS: Seven main subgroups of patients with specific symptom characteristics were identified, including M3, M2, M1, M5, M0, M29 and M4. M3 and M0 subgroups had prominent posterior circulatory symptoms, while M3 was associated with autonomic disorders, and M4 manifested as anxiety; M2 and M4 had motor and motor coordination disorders; M1 had sensory disorders; M5 had more obvious lung infections; M29 had a disorder of consciousness. The specificity of CM syndromes of each subgroup was as follows. M3, M2, M1, M0, M29 and M4 all had the same syndrome as wind phlegm pattern; M3 and M0 both showed hyperactivity of Gan (Liver) yang pattern; M2 and M29 had similar syndromes, which corresponded to intertwined phlegm and blood stasis pattern and phlegm-stasis obstructing meridians pattern, respectively. The manifestations of CM syndromes often appeared in a combination of 2 or more syndrome elements. The most common combination of these 7 subgroups was wind-phlegm. The 7 subgroups of CM syndrome elements were specifically manifested as pathogenic wind, pathogenic phlegm, and deficiency pathogens. CONCLUSIONS There were 7 main symptom similarity-based subgroups in ischemic stroke patients, and their specific characteristics were obvious. The main syndromes were wind phlegm pattern and hyperactivity of Gan yang pattern.

The present study aimed to investigate the composition of the terpene synthase(TPS) gene family in Gynostemma pentaphyllum and its role in abiotic stresses. The G. pentaphyllum TPS gene family was identified and analyzed at the genome-wide level using bioinformatics analysis, and the expression patterns of these family members were analyzed in different tissues of G. pentaphyllum as well as under various abiotic stresses. The results showed that there were 24 TPS gene family members in G. pentaphyllum with protein lengths ranging from 294 to 842 aa. All of them were localized in the cytoplasm or chloroplasts and unevenly distributed on the 11 chromosomes of G. pentaphyllum. The results of the phylogenetic tree showed that the G. pentaphyllum TPS gene family members could be divided into five subfamilies. As revealed by the analysis of promoter cis-acting elements, TPS gene family members in G. pentaphyllum were predicted to respond to a variety of abiotic stresses such as salt, low temperature, and dark stress. The analysis of gene expression patterns in different tissues of G. pentaphyllum revealed that nine TPS genes were tissue-specific in expression. The qPCR results showed that GpTPS16, GpTPS17, and GpTPS21 responded to a variety of abiotic stresses. This study is expected to provide references in guiding the further exploration of the biological functions of G. pentaphyllum TPS genes under abiotic stresses.

Wound healing is a slow and complex biological process, including inflammatory reaction, cell proliferation, cell differentiation, cell migration, angiogenesis, extracellular matrix deposition, tissue remodeling, and so on. Wnt signaling pathway can be divided into classical pathway and non-classical pathway. Wnt classical pathway, also known as Wnt/β-catenin signaling pathway, plays an important role in cell differentiation, cell migration, and maintenance of tissue homeostasis. Many inflammatory factors and growth factors are involved in the upstream regulation of this pathway. The activation of Wnt/β-catenin signaling pathway plays an important role in the occurrence, development, regeneration, repair and related treatment of skin wounds. This article review the relationship between Wnt/β-catenin signaling pathway and wound healing, meanwhile summarizes its effects on important processes of wound healing, such as inflammation, cell proliferation, angiogenesis, hair follicle regeneration, and skin fibrosis, as well as the role of inhibitors of Wnt signaling pathway in wound healing.

Objective:To investigate the clinical efficacy of electrical stimulation, biofeedback, and radiofrequency therapy in combination for the treatment of pelvic floor dysfunction.Methods:A total of 144 patients with pelvic floor dysfunction who received treatment in Lianyungang Maternal and Child Health Hospital from June 2020 to June 2022 were included in this prospective randomized controlled study. They were randomly assigned to undergo electrical stimulation combined with biofeedback (electrical stimulation group, n = 48), treatment with a novel radiofrequency technique (radiofrequency therapy group, n = 48), or electrical stimulation, biofeedback, and treatment with a novel radiofrequency technique (combined group, n = 48). Pelvic floor dysfunction, stress urinary incontinence, and pelvic floor myofascial pain were compared among the three groups. Pelvic organ prolapse quantification was compared among the three groups before and after treatment. Quality of life was evaluated. Results:The effective rates of treatment against pelvic floor dysfunction, stress urinary incontinence, and pelvic floor myofascial pain in the combined group were 95.83% (46/48), 97.92% (47/48), and 93.75% (45/48), respectively, which were significantly higher than 79.17% (38/48), 79.17% (38/48), 77.08% (37/48) in the radiofrequency group, and 75.00% (36/48), 77.08% (37/48), 72.92% (35/48) in the electrical stimulation group ( χ2 = 8.40, 9.77, 7.66, all P < 0.05). After treatment, the severity of pelvic organ prolapse in the combined group was significantly milder than that in the novel radiofrequency technique group and electrical stimulation group (both P < 0.05). The scores of the pelvic floor dysfunction questionnaire and urinary incontinence questionnaire in the combined group were significantly lower than those in the radiofrequency therapy group and the electrical stimulation group (both P < 0.05). Conclusion:Electrical stimulation, biofeedback, and radiofrequency therapy in combination can greatly strengthen the muscle strength of the pelvic floor, relieve urinary incontinence, reduce pelvic floor myofascial pain, and improve the quality of life of patients with pelvic floor dysfunction.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

Objective:To observe the effect of Ba Duan Jin(Eight-brocade Exercise)plus Tuina(Chinese therapeutic massage)in treating primary dysmenorrhea due to cold-induced blood stasis in female college students and on the score of fatigue scale-14(FS-14). Methods:Seventy-two female college students with primary dysmenorrhea due to cold-induced blood stasis were randomized into a Tuina group and a joint group,with 36 cases in each group.The Tuina group only received Tuina manipulations.In the joint group,besides the same Tuina manipulations,patients practiced Ba Duan Jin.For both groups,the once-daily intervention was conducted from 6 d before the menstrual period until menstrual day 1 for 3 menstrual cycles.Changes in the scores of COX menstrual symptom scale(CMSS),visual analog scale(VAS),and FS-14 after the intervention were observed.Clinical efficacy was also estimated. Results:During the process,1 case dropped out in the Tuina group,and 35 cases completed the intervention;2 cases dropped out in the joint group,and 34 cases completed the intervention.The total effective rate was 94.1%in the joint group,higher than 88.6%in the Tuina group(P<0.05).After treatment,the symptom duration and intensity scores in the scores of CMSS,VAS,and FS-14 declined in both groups(P<0.05 or P<0.01);the CMSS symptom duration score and FS-14 score were lower in the joint group than in the Tuina group(P<0.05). Conclusion:Tuina manipulations alone or combined with Ba Duan Jin practice can effectively treat primary dysmenorrhea due to cold-induced blood stasis in female college students;when combined with Ba Duan Jin practice,Tuina manipulations can more significantly improve pain duration and fatigue,suggesting the advantages of combining Tuina Gongfa and manipulations.
