摘要：
BACKGROUND: Rosacea, a common chronic inflammatory skin disease worldwide, is currently incurable with complex pathogenesis. Dendrobium polysaccharide (DOP) may exert therapeutic effects on rosacea via acting on the NF-κB-related inflammatory and oxidative processes. MATERIALS AND METHODS: In this study, an LL-37-induced rosacea-like mouse model was established. HE staining was used to assess the skin lesions, erythema severity scores, pathological symptoms, and inflammatory cell numbers of mice in each group. The inflammation level was quantitatively analyzed using enzyme-linked immunosorbent assay (ELISA) and reverse transcription-quantitative real-time polymerase chain reaction (RT-qPCR). The expression levels of TLR4 and p-NF-κB were finally detected. RESULTS: DOP improved skin pathological symptoms of rosacea mice. DOP also alleviated the inflammation of rosacea mice. Moreover, the TLR4/NF-κB pathway was observed to be inhibited in the skin of mice after DOP application. These findings evidenced the anti-inflammatory effects of DOP on the LL-37-induced rosacea mouse model. DOP could inhibit NF-κB activation, suppress neutrophil infiltration, and reduce pro-inflammatory cytokines production, which may be the reason for DOP protecting against rosacea. CONCLUSION: This study may propose an active candidate with great potential for rosacea drug development and lay a solid experimental foundation for promoting DOP application in rosacea therapy.

AIMS: This work aims to analyse the current state of the professional identity of Chinese nurses; examine the relationship amongst regulatory focus, organizational silence and professional identity and determine how regulatory focus affects the relationship between professional identity and organizational silence. DESIGN: This study conducted a cross-sectional survey. METHODS: From June to August 2023, 420 nurses from six hospitals in Hunan Province, China, were selected through convenience sampling and surveyed by using a general information questionnaire, the regulatory focus scale, the organizational silence scale and the professional identity scale. The relationship amongst the regulatory focus, organizational silence and professional identity of nurses was examined by utilizing SPSS 25.0 and the mediating role of regulatory focus between organizational silence and nurses' professional identity was examined by applying AMOS 24.0. RESULTS: Nurses had a moderate level of professional identity. Professional identity was positively correlated with regulatory focus and negatively correlated with organizational silence. Regulatory focus was negatively correlated with organizational silence. Mediation effect studies revealed that organizational silence and professional identity were partially mediated by regulatory focus. CONCLUSION: In accordance with research showing that nurses' organizational silence can indirectly affect professional identity via regulatory focus, clinical nursing managers should concentrate on the interaction amongst these three variables to strengthen professional identity. IMPACT: The results of this study serve as a reminder to nurses to select a preventive or promotive focus based on their career objectives and to effectively express their views to enhance their professional identity. This also reminds nursing managers assess nurse-led regulatory focus, identify their underlying qualities and understand their professional aspirations and career orientation, create a good atmosphere for advice and encourage nurses to express their views, so as to improve nurses 'professional identity.

摘要：
ETHNOPHARMACOLOGICAL RELEVANCE: Anxiety disorders leads to a decline in quality of life and increased risk of morbidity and mortality. The Baihe Dihuang decoction (BDD) is a classic Chinese medical formula that has been widely used to treat anxiety disorders for thousands of years in China. However, the pharmacodynamic material that is responsible for the antianxiety of BDD remains unclear. AIM OF THE STUDY: To screen the main ingredients of anti-anxiety in BDD based on the establishment of spectrum-effect relationship and verified experiment. METHODS: The UPLC-Q-TOF/MS technique was utilized to establish fingerprints of various fractions of BDD and identify the main compounds. The anti-anxiety effects of BDD were comprehensively evaluated through multiple assessments, including the open field test, elevated plus maze test, and neurotransmitters tests. Then, the spectrum-effect relationship was established through Pearson correlation analysis, gray correlation analysis, orthogonal partial least squares regression analysis. The spectrum-effect relationship results were confirmed through various measures on an anxiety condition cell model, induced by a corticosterone and lipopolysaccharide intervention. These measures included assessing neuronal cell viability, morphology, apoptosis, synaptic damage, and the expression of neurotransmitters and inflammatory factors. RESULTS: In the UPLC-Q-TOF-MS fingerprint, 46 common peaks were identified. The pharmacological results indicated that different fractions of BDD have strong effects on improving anxiety-like behavior and regulating neurotransmitters. Among them, butanol fraction has the highest comprehensive evaluation score of anti-anxiety efficacy, which is main active fraction of BDD for anti-anxiety. The analysis of the spectrum-effect relationship revealed that the 46 peaks exhibited varying degrees of correlation with the anti-anxiety efficacy indicators of BDD. Among them, 14 components have a high correlation with the anti-anxiety efficacy indicators, which may be the potential anti-anxiety efficacy components of BDD. The in vitro activity verification of active components verified our prediction, regaloside A, B, C, D, H, acteoside, and isoacteoside improved neuronal cell viability, cell morphology, apoptosis, and synaptic damage. Additionally, regaloside A, B, C, D, H and acteoside regulated the neurotransmitter levels, while regaloside A, B, C, D, acteoside and isoacteoside inhibited the levels of inflammatory cytokines. CONCLUSION: The butanol fraction was found to be the main active fraction of BDD, and 14 compounds were the major anxiolytic active components. The results of verifying the major active components were consistent with the predicted results of the spectrum-effect analysis. The developed spectrum-effect analysis in this study demonstrates high accuracy and reliability for screening active components in TCMs.

摘要：
Background: Common symptoms of Chronic Non-atrophic Gastritis (CNAG) include nausea, stomach distension, and abdominal pain. The Houtou Jianweiling Tablet (HTJWT) is a chinese patent medicine (CN1368229A) and it has been used clinically for more than 20years with proven clinical efficacy in treating CNAG, prompted us to establish the clinical efficacy and safety of HTJWT on patients with mild to moderate CNAG symptoms in Pakistani population. Methods: This phase II, double-blind, randomized, parallel-controlled trial was conducted in a single center between November 2022 and February 2023 in Pakistan. In a ratio of 1:1, total 240 CNAG patients with erosion identified by pathological biopsy and gastroscopy were randomly assigned to control (Omeprazole) group (n = 120) and the treatment (HTJWT) group (n = 120). Patients in the treatment group received orally four HTJWT (0.38g/tablet), three times a day and one placebo of Omeprazole enteric-coated tablet prior to breakfast, daily. On the other hand, patients in the control group received one Omeprazole enteric-coated tablet (20 mg/tablet) prior to breakfast and four placebo of HTJWT, thrice a day. The patients consumed the investigated drugs (i.e., treatment and control) treatment regimen was followed for a duration of 28days. The safety of the patients were evaluated through adverse events, serious adverse events and laboratory tests such as blood biochemistry, urine analysis, liver and renal function tests. Vital signs like; blood pressure, pulse rate, body temperature, respiratory rate for all the patients were recorded. The cardiac status of the patients were assessed through electrocardiogram (ECG). The primary efficacy indicators were the improvement rate of gastric distention and gastralgia as the main clinical symptoms. Secondary indicators were visual analogue score (VAS); improvement rate of secondary clinical symptoms and signs; improvement rate of total clinical signs and symptoms; the disappearance/remission rate of Gastric pain and, remission/disappearance time of gastric distension; and the negative conversion rate of Helicobacter pylori (H. pylori). The outcomes among each group were compared using the chi-square test. Results: Patients in both groups had good drug compliance (80%-120%), and there was no statistically significant difference in the patients' baseline characteristics. The clinical improvement rate was found to be 91.1% in the treatment group and 91.0% in the control group with negligible variation among the two groups (p = 0.9824; 95% confidence interval: -0.0781-0.0798). Similarly, hardly no difference was found in the negative conversion rate of H. pylori between the treatment group and the control group (i.e., 70.1% and 71.8% respectively, p = 0.8125). There were no significant differences in respiratory rate, vital signs, blood pressure, laboratory results for blood biochemistry, urine analysis, liver and renal function tests between the two groups. The ECG assessment carried out for the treatment and control group revealed no considerable difference. Margin variation in the disappearance time of gastric pain (p = 0.1860) and remission rate (p = 0.5784) between the two groups were observed. The control group exhibited a faster remission period for gastrointestinal discomfort indications as compared to treatment group (p = 0.0430). Only one patient in the control group experienced mild to moderate adverse events, namely,; epigastric pain and dyspepsia. The results were consistent with the intention-to-treat and per-protocol analysis that included patients who were 100% compliant to the assigned therapy. Conclusion: The lower limit of confidence interval (CI, 95%) for the differences in the effective rate between the treatment and the control groups was found to be -0.0781 which is greater than -0.15, hence the treatment group is non-inferior to the control group. The therapeutic dosage used in the trial and treatment period did not cause any significant adverse event, and there were no obvious changes in the ECG profile, vital signs and biochemistry of the patients. Based on the clinical efficacy evaluation and reported adverse events, it can be concluded that the HTJWT is a safe and effective traditional chinese medicine for the treatment of patients suffering from chronic non-atrophic gastritis with mild to moderate symptoms.

Acute mastitis;Blood-milk barrier;Lipopolysaccharides;Prunella vulgaris L.
摘要：
ETHNOPHARMACOLOGICAL RELEVANCE: According to ancient literature, Prunella vulgaris L. (P vulgaris) alleviates mastitis and has been used in China for many years; however, there are no relevant reports that confirm this or the mechanism of its efficacy. AIM OF THE STUDY: To explore the anti-acute mastitis effect and potential mechanism of P vulgaris extract. MATERIALS AND METHODS: First, the active ingredients and targets of P vulgaris against mastitis were predicted using network pharmacology. Next, the relevant active ingredients were enriched using macroporous resins and verified using UV and UPLC-Q-TOF-MS/MS. Lastly, a mouse model of acute mastitis was established by injecting lipopolysaccharides into the mammary gland and administering P vulgaris extract by oral gavage. The pathological changes in mammary tissue were observed by HE staining. Serum and tissue inflammatory factors were measured by ELISA method. MPO activity in mammary tissue was measured using colorimetry and MPO expression was detected by immunohistochemistry. The expression of tight junction proteins (ZO-1, claudin-3, and occludin) in mammary tissue was detected by immunofluorescence and Western blot. iNOS and COX-2 in mammary tissue were detected by Western blot. MAPK pathway and NF-κB pathway related proteins were also detected by Western blot. RESULTS: Network pharmacology predicted that phenolic acids and flavonoids in P vulgaris had anti-mastitis effects. The contents of total flavonoids and total phenolic acids in P vulgaris extract were 64.5% and 29.4%, respectively. UPLC-Q-TOF-MS/MS confirmed that P vulgaris extract contained phenolic acids and flavonoids. The results of animal experiments showed that P vulgaris extract reduced lipopolysaccharide-induced inflammatory edema, inflammatory cell infiltration, and interstitial congestion of mammary tissue. It also reduced the levels of serum and tissue inflammatory factors TNF-α, IL-6, and IL-1β, and inhibited the activation of MPO. Furthermore, it downregulated the expression of MAPK and NF-κB pathway-related proteins. The expressions of ZO-1, occludin, and claudin-3 in mammary gland tissues were upregulated. CONCLUSIONS: P vulgaris extract can maintain the integrity of mammary connective tissue and reduce its inflammatory response to prevent acute mastitis. Its mechanism probably involves regulating NF-κB and MAPK pathways.

triple negative breast cancer;RhoA;ROCK1;Ezrin;scutellaria barbata D.Don extract
摘要：
Background
Triple-negative breast cancer (TNBC) lacks effective therapeutic targets. Scutellaria barbata D.Don (SB) has been revealed to have anti-breast cancer (BC) effect, but the effect of SB extract in TNBC is still unclear. Herein, this research delves into the underlying mechanism.
Methods
SB was extracted by solvent extraction, and the main components were identified using an Agilent 6,520 HPLC-Chip/Q-TOF (Chip/Q-TOF) MS system. In vitro cell experiments were conducted. The effects of SB extract alone, SB extract plus EGF, GSK alone, GSK plus Ezrin overexpression, or SB extract plus Ezrin overexpression on cell viability, invasion, migration, and apoptosis were examined by cell function experiments. The apoptosis- and RhoA/ROCK1 pathway-related protein levels were analyzed by western blot assay.
Results
Mass spectrometry analysis exhibited that SB extract mainly contains long-chain fatty acids and ursolic acid. SB extract mitigated TNBC cell biological phenotypes, apoptosis- and RhoA/ROCK1 pathway-related marker expressions, which were reversed by EGF. The further results found that GSK obviously weakens TNBC cell biological behaviors, apoptosis- and RhoA/ROCK1 signaling-related protein levels, while oe-Ezrin treatment reverses the effect of GSK on TNBC cells. Moreover, SB extract regulated Ezrin-mediated function of TNBC cells by impeding the RhoA/ROCK1 pathway.
Conclusion
Our findings demonstrated that SB extract regulated Ezrin-mediated proliferation, migration, invasion, and apoptosis of TNBC cells via suppressing the RhoA /ROCK1 signaling. Our results offer the experimental foundation for further investigation of the anti-cancer role of SB in TNBC cells.
Highlights
SB extract inhibits the biological phenotypes of TNBC cells. SB extract inhibits the biological behaviors of TNBC cells through the RhoA/ROCK1 pathway. SB extract modulates Ezrin-mediated TNBC cell proliferation, migration, invasion, and apoptosis via restraining the RhoA/ROCK1 signaling.

摘要：
Salvianolic acid B (Sal B) is the primary water-soluble bioactive constituent derived from the roots of Salvia miltiorrhiza Bunge. This research was designed to reveal the potential mechanism of Sal B anti-liver injury from the perspective of macrophages. In our lipopolysaccharide-induced M1 macrophage model, Sal B showed a clear dose-dependent gradient of inhibition of the macrophage trend of the M1 type. Moreover, Sal B downregulated the expression of lactate dehydrogenase A (LDHA), while the overexpression of LDHA impaired Sal B's effect of inhibiting the trend of macrophage M1 polarization. Additionally, this study revealed that Sal B exhibited inhibitory effects on the lactylation process of histone H3 lysine 18 (H3K18la). In a ChIP-qPCR analysis, Sal B was observed to drive a reduction in H3K18la levels in the promoter region of the LDHA, NLRP3, and IL-1β genes. Furthermore, our in vivo experiments showed that Sal B has a good effect on alleviating CCl(4)-induced liver injury. An examination of liver tissues and the Kupffer cells isolated from those tissues proved that Sal B affects the M1 polarization of macrophages and the level of histone lactylation. Together, our data reveal that Sal B has a potential mechanism of inhibiting the histone lactylation of macrophages by downregulating the level of LDHA in the treatment of liver injury.
