Mechanistic insights into Qiteng Xiaozhuo Granules' regulation of autophagy for chronic glomerulonephritis treatment: Serum pharmacochemistry, network pharmacology, and experimental validation.

ETHNOPHARMACOLOGICAL RELEVANCE: Qiteng Xiaozhuo Granules (QTXZG), a traditional Chinese medicine prescription, is widely acknowledged for its therapeutic efficacy and lack of discernible toxicity in clinical practice, substantiating its potential in the treatment of chronic glomerulonephritis (CGN). Nevertheless, the specific effectiveness and underlying mechanisms of QTXZG remain insufficiently explored. AIM OF THE STUDY: The purpose of this study was to explore the mechanism of the QTXZG in the treatment of CGN via targeting autophagy based on serum pharmacochemistry, network pharmacology, and experimental validation. METHODS: Serum samples from SD rats orally administered QTXZG were analyzed using UPLC-QE/MS to identify contained compounds. Network and functional enrichment analyses elucidated QTXZG's targets and biological mechanisms. Reliability was ensured through molecular docking, in vivo and in vitro experiments. RESULTS: After oral administration of QTXZG, 39 enriched compounds in serum samples collected 1 h later were identified as potential active agents, with 508 potential targets recognized as QTXZG-specific targets. Through integration of various databases, intersection analysis of QTXZG targets, CGN-related genes, and autophagy-related targets identified 10 core autophagy-related targets for QTXZG in CGN. GO and KEGG analyses emphasized their roles in autophagy, inflammation, and immune processes, particularly emphasizing the enrichment of the AMPK/mTOR signaling pathway. Molecular docking results demonstrated strong binding affinities between QTXZG's key compounds and the predicted core targets. In animal experiments, QTXZG was found to ameliorate renal tissue damage in CGN model mice, significantly reducing serum creatinine (Scr) and blood urea nitrogen (BUN) levels. Importantly, both animal and cell experiments revealed QTXZG's ability to decrease excessive ROS and inflammatory factor release in mesangial cells. Furthermore, in vitro and in vivo experiments confirmed QTXZG's capacity to upregulate Beclin1 and LC3II/I expression, decrease p62 expression, and induce CGN autophagy through modulation of the AMPK/mTOR pathway. CONCLUSIONS: This study indicated that QTXZG can induce autophagy in CGN by affecting the AMPK/mTOR pathway, and induction of autophagy may be one of the possible mechanisms of QTXZG's anti-CGN.

Work Productivity Among Younger Breast Cancer Survivors: The Impact of Behavioral Interventions for Depression.

OBJECTIVES: The Pathways to Wellness randomized controlled trial found that 2 behavioral interventions, mindfulness awareness practices and survivorship education, reduced depressive symptoms in younger breast cancer survivors (BCSs) compared with wait-list control. This secondary analysis examines whether the interventions led to reduced loss of work productivity among younger BCSs and whether such reductions were mediated by reductions in depressive symptoms. METHODS: The Work Productivity and Activity Impairment scale was used to measure work productivity loss at 4 assessment time points. Correlates of productivity loss at enrollment were examined using multivariable linear regression. Differences in change over time in productivity loss between each intervention group and control were assessed using linear mixed models. Reduced depressive symptoms were tested as a mediator of reduced productivity loss. RESULTS: Of 247 trial participants, 199 were employed and included in the analyses. At enrollment, higher productivity loss was associated with chemotherapy receipt (P = .003), younger age (P = .021), more severe cognitive problems (P = .002), higher musculoskeletal pain severity (P = .002), more depressive symptoms (P = .016), and higher fatigue severity (P = .033). The mindfulness intervention led to significantly less productivity loss compared with control at all 3 postintervention assessment points (all P < .05), with about 54% of the effect mediated by reduction in depressive symptoms. Survivorship education was not associated with reduced loss of productivity. CONCLUSIONS: These findings suggest that addressing depressive symptoms through behavioral interventions, such as mindfulness, may mitigate impacts on work productivity in younger BCSs.

Andrographolide Attenuates Oxidized LDL-Induced Activation of the NLRP3 Inflammasome in Bone Marrow-Derived Macrophages and Mitigates HFCCD-Induced Atherosclerosis in Mice.

Andrographolide (AND) is a bioactive component of the herb Andrographis paniculata and a well-known anti-inflammatory agent. Atherosclerosis is a chronic inflammatory disease of the vasculature, and oxidized LDL (oxLDL) is thought to contribute heavily to atherosclerosis-associated inflammation. The aim of this study was to investigate whether AND mitigates oxLDL-mediated foam cell formation and diet-induced atherosclerosis (in mice fed a high-fat, high-cholesterol, high-cholic acid [HFCCD] diet) and the underlying mechanisms involved. AND attenuated LPS/oxLDL-mediated foam cell formation, IL-1[Formula: see text] mRNA and protein (p37) expression, NLR family pyrin domain containing 3 (NLRP3) mRNA and protein expression, caspase-1 (p20) protein expression, and IL-1[Formula: see text] release in BMDMs. Treatment with oxLDL significantly induced protein and mRNA expression of CD36, lectin-like oxLDL receptor-1 (LOX-1), and scavenger receptor type A (SR-A), whereas pretreatment with AND significantly inhibited protein and mRNA expression of SR-A only. Treatment with oxLDL significantly induced ROS generation and Dil-oxLDL uptake; however, pretreatment with AND alleviated oxLDL-induced ROS generation and Dil-oxLDL uptake. HFCCD feeding significantly increased aortic lipid accumulation, ICAM-1 expression, and IL-1[Formula: see text] mRNA expression, as well as blood levels of glutamic pyruvic transaminase (GPT), total cholesterol, and LDL-C. AND co-administration mitigated aortic lipid accumulation, the protein expression of ICAM-1, mRNA expression of IL-1[Formula: see text] and ICAM-1, and blood levels of GPT. These results suggest that the working mechanisms by which AND mitigates atherosclerosis involve the inhibition of foam cell formation and NLRP3 inflammasome-dependent vascular inflammation as evidenced by decreased SR-A expression and IL-1[Formula: see text] release, respectively.

Pilot study of a Spanish language measure of financial toxicity in underserved Hispanic cancer patients with low English proficiency.

Background: Financial toxicity (FT) reflects multi-dimensional personal economic hardships borne by cancer patients. It is unknown whether measures of FT-to date derived largely from English-speakers-adequately capture economic experiences and financial hardships of medically underserved low English proficiency US Hispanic cancer patients. We piloted a Spanish language FT instrument in this population. Methods: We piloted a Spanish version of the Economic Strain and Resilience in Cancer (ENRICh) FT measure using qualitative cognitive interviews and surveys in un-/under-insured or medically underserved, low English proficiency, Spanish-speaking Hispanics (UN-Spanish, n = 23) receiving ambulatory oncology care at a public healthcare safety net hospital in the Houston metropolitan area. Exploratory analyses compared ENRICh FT scores amongst the UN-Spanish group to: (1) un-/under-insured English-speaking Hispanics (UN-English, n = 23) from the same public facility and (2) insured English-speaking Hispanics (INS-English, n = 31) from an academic comprehensive cancer center. Multivariable logistic models compared the outcome of severe FT (score > 6). Results: UN-Spanish Hispanic participants reported high acceptability of the instrument (only 0% responded that the instrument was "very difficult to answer" and 4% that it was "very difficult to understand the questions"; 8% responded that it was "very difficult to remember resources used" and 8% that it was "very difficult to remember the burdens experienced"; and 4% responded that it was "very uncomfortable to respond"). Internal consistency of the FT measure was high (Cronbach's α = 0.906). In qualitative responses, UN-Spanish Hispanics frequently identified a total lack of credit, savings, or income and food insecurity as aspects contributing to FT. UN-Spanish and UN-English Hispanic patients were younger, had lower education and income, resided in socioeconomically deprived neighborhoods and had more advanced cancer vs. INS-English Hispanics. There was a higher likelihood of severe FT in UN-Spanish (OR = 2.73, 95% CI 0.77-9.70; p = 0.12) and UN-English (OR = 4.13, 95% CI 1.13-15.12; p = 0.03) vs. INS-English Hispanics. A higher likelihood of severely depleted FT coping resources occurred in UN-Spanish (OR = 4.00, 95% CI 1.07-14.92; p = 0.04) and UN-English (OR = 5.73, 95% CI 1.49-22.1; p = 0.01) vs. INS-English. The likelihood of FT did not differ between UN-Spanish and UN-English in both models (p = 0.59 and p = 0.62 respectively). Conclusion: In medically underserved, uninsured Hispanic patients with cancer, comprehensive Spanish-language FT assessment in low English proficiency participants was feasible, acceptable, and internally consistent. Future studies employing tailored FT assessment and intervention should encompass the key privations and hardships in this population.

[Effects of shading intensity on growth and quality of Artemisia stolonifera].

The purpose of this study was to analyze the effects of shading intensity on the growth, yield, and quality of Artemisia stolonifera so as to provide references for the artificial cultivation of A. stolonifera. The seedlings of A. stolonifera with consistent growth underwent shading treatment at four shading intensity levels(0, 55%, 85%, and 95%) with different layers of black shading nets. The agronomic indexes, yield, moxa yield, total ash, quality characteristics of moxa during combustion and pyrolysis, main volatile components, flavonoids, and phenolic acids were measured. The results showed that under shading conditions, the stem diameter, leaf width, 5-leaf spacing, branch number, and yield of A. stolonifera decreased significantly, while the plant height, leaf length, leaf number, chlorophyll content, and moxa yield increased first and then decreased with the increase in shading intensity. The burning performance of moxa under natural light was better than that under moderate and severe shading conditions. The content of eucalyptol first increased and then decreased with the increase in shading intensity. The humulene content was negatively correlated with shading intensity. Other major volatile components showed no significant difference under various shading conditions. The content of neochlorogenic acid, cryptochlorogenic acid, isoschaftoside, and isochlorogenic acid B was positively correlated with shading intensity, while the content of chlorogenic acid, isochlorogenic acid A, and isochlorogenic acid C decreased first and then increased with the increase in shading intensity. To sum up, A. stolonifera is a light-loving plant, and shading can greatly reduce the yield, the content of internal components, and the burning performance of moxa. It is the main reason why A. stolonifera is mainly distributed in the forest edge, open forest, roadside, and wasteland grass in the middle and high mountains in the wild. For artificial domestication and cultivation of A. stolonifera, it is better to select plots with sufficient light.

[Comparison of growth and quality of wild and cultivated Artemisia stolonifera].

This paper aims to compare the difference of growth and quality between wild and cultivated Artemisia stolonifera, thereby providing references for further development and utilization of A. stolonifera. The wild and cultivated A. stolonifera from different altitudes were collected, and the agronomic characters, moxa yield, volatile components, flavonoids, and phenolic acids were determined. The results showed that the cultivated species were taller and stronger, with more leaves and branches, than the wild species. The moxa yield and combustion quality of wild products were higher than those of cultivated products. The content of main volatile components in cultivated products was higher than that in wild products. The content of flavonoids and phenolic acids in wild products was higher than that in cultivated products. At high altitude, the ignition performance, combustion persistence, comprehensive combustion performance, and heat release during combustion of the wild and cultivated A. stolonifera. were optimal. At middle altitude, the content of main characteristic volatile components and flavone phenolic acids in the leaves of the cultivated and wild A. stolonifera were the highest. At low altitude, the combustion quality and the content of the above components of the cultivated A. stolonifera decrease significantly. Considering the combustion quality and the content of the internal components of the leaf lint, the middle and high altitude areas are suitable for the artificial cultivation of A. stolonifera.

[Distinguishing between Artemisia stolonifera and A. argyi by specific PCR of leaves and non-glandular trichomes].

Artemisia stolonifera is a relative of A. argyi. The two species are difficult to be distinguished due to the similarity in leaf shape and have even less distinctive features after processing. This study aims to establish a method to quickly distinguish between them. At the same time, we examined the reasonability and applicability of the specific polymerase chain reaction(PCR) method. The C/T single nucleotide polymorphism was detected at the position 202 of the sequence, based on which specific primers were designed to identify these two species. The PCR with the specific primer JNC-F and the universal primer ITS3R produced a specific band at 218 bp for A. argyi and no band for A. stolonifera, which can be used to detect at least 3% of A. argyi samples mixed in A. stolonifera samples. The PCR with the specific primer KY-F and the universal primer ITS3R produced a specific band at 218 bp for A. stolonifera and no band for A. argyi, which can be used to detect at least 5% of A. stolonifera samples mixed with A. argyi. The limit of detection of the established method was 5 ng DNA. The established PCR method can accurately distinguish between A. stolonifera and A. argyi, which provides an experimental basis for the quality control of A. stolonifera and determines whether the herbs are adulterated.

Antipruritic effects of geraniol on acute and chronic itch via modulating spinal GABA/GRPR signaling.

BACKGROUND AND PURPOSE: Itch (pruritus) is a common unpleasant feeling, often accompanied by the urge of scratching the skin. It is the main symptom of many systemic and skin diseases, which can seriously affect the patient's quality of life. Geraniol (GE; trans-3,7-dimethyl-2,6-octadien-1-ol) is a natural monoterpene with diverse effects, including anti-inflammatory, antioxidant, neuroprotective, anti-nociceptive, and anticancer properties. The study aims to examine the effects of GE on acute and chronic itch, and explore the underlying mechanisms. METHODS: Acute itch was investigated by using Chloroquine and compound 48/80 induced model, followed by manifestation of diphenylcyclopropenone (DCP)-induced allergic contact dermatitis and the acetone-ether-water (AEW)-induced dry skin model in mice. The scratching behavior, skin thickness, c-Fos expression, and GRPR protein expression in the spinal cord were subsequently monitored and evaluated by behavioral tests as well as pharmacological and pharmacogenetic technologies. RESULTS: Dose-dependent intraperitoneal injection of GE alleviated the acute itch, induced by chloroquine and compound 48/80, as well as increased the spinal c-Fos expression. Intrathecal administration of GE suppressed the GABAA receptor inhibitor bicuculline-induced itch, GRP-induced itch, and the GABAergic neuron inhibition-induced itch. Furthermore, the subeffective dose of bicuculline blocked the anti-pruritic effect of GE on the chloroquine and compound 48/80 induced acute itch. GE also attenuated DCP and AEW-induced chronic itch, as well as the increase of spinal GRPR expression in DCP mice. CONCLUSION AND IMPLICATIONS: GE alleviates both acute and chronic itch via modulating the spinal GABA/GRPR signaling in mice. Findings of this study reveal that GE may provide promising therapeutic options for itch management. Also, considering the pivotal role of essential oils in aromatherapy, GE has great application potential in aromatherapy for treating skin diseases, and especially the skin with severe pruritus.

The pulmonary biopharmaceutics and anti-inflammatory effects after intratracheal and intravenous administration of Re-Du-Ning injection.

BACKGROUND: Re-Du-Ning injection (RDN) is a renowned heat-clearing traditional Chinese medicine for the treatment of respiratory diseases owing to its anti-inflammatory effects. However, very little is known about the pulmonary distribution and lung exposure-efficacy relationships. This study aimed to investigate the pulmonary distribution and biopharmaceutics concerning lung penetrability and affinity and the local anti-inflammatory effects after intravenous and pulmonary administration of RDN. METHODS: Two iridoids and seven phenolic acid components were selected as the chemical markers in RDN. The in vitro pulmonary distribution and biopharmaceutics were conducted by evaluating the binding and disassociation kinetics of chemical markers in lung tissue explants whereas the in vivo evaluation was performed by determining the time-dependent concentrations of chemical markers in plasma, lung epithelial lining fluid (ELF), lung tissues and immune cells in the ELF after intratracheal and intravenous administrations of RDN. The inhibitory effects on tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) production were used to evaluate the anti-inflammatory effect of RDN on lung tissues in vitro and on mice with LPS-induced lung inflammation. RESULTS: The chemical markers of RDN exhibited excellent lung penetrability but poor lung affinity in vitro and in vivo. After intravenous administration, the chemical markers appeared to rapidly penetrate through the lung tissue to reach the ELF, leading to markedly higher drug exposure to ELF and immune cells in the ELF than to lung tissues. Compared to intravenous injection, the intratracheal instillation of RDN increased drug exposure to lung tissue and immune cells in the ELF by up to > 80-fold, leading to improved anti-inflammatory potency and prolonged duration of action. CONCLUSION: The drug exposure to immune cells in the ELF was correlated with the lung-targeted anti-inflammatory effects of RDN and pulmonary delivery has the potential to replace intravenous injection of RDN for the treatment of respiratory diseases.

Synthesis of selenophene-based chalcone analogs and assessment of their biological activity as anticancer agents.

Selenium is an essential micronutrient that is beneficial to human health. Selenium-containing drugs have been developed as antioxidants, anti-inflammatory, and anticancer agents. However, the synthesis of selenium-containing chalcones has not been fully explored. Therefore, we report the synthesis of novel selenophene-based chalcone analogs and reveal their biological activities as anticancer agents. Among the seven synthesized molecules, compounds 6, 8, and 10 exhibited anticancer activity with IC50 values of 19.98 ± 3.38, 38.23 ± 3.30, and 46.95 ± 5.68 µM, respectively, against human colorectal adenocarcinoma (HT-29) cells. Clonogenic assays and Western blot analysis tests further confirmed that compound 6 effectively induced apoptosis in HT-29 cells through mitochondrial- and caspase-3-dependent pathways.

Andrographolide Inhibits Lipotoxicity-Induced Activation of the NLRP3 Inflammasome in Bone Marrow-Derived Macrophages.

Andrographolide is the major bioactive component of the herb Andrographis paniculata and is a potent anti-inflammatory agent. Obesity leads to an excess of free fatty acids, particularly palmitic acid (PA), in the circulation. Obesity also causes the deposition of ectopic fat in nonadipose tissues, which leads to lipotoxicity, a condition closely associated with inflammation. Here, we investigated whether andrographolide could inhibit PA-induced inflammation by activating autophagy, activating the antioxidant defense system, and blocking the activation of the NLRP3 inflammasome. Bone marrow-derived macrophages (BMDMs) were primed with lipopolysaccharide (LPS) and then activated with PA. LPS/PA treatment increased both the mRNA expression of NLRP3 and IL-1[Formula: see text] and the release of IL-1[Formula: see text] in BMDMs. Andrographolide inhibited the LPS/PA-induced protein expression of caspase-1 and the release of IL-1[Formula: see text]. Furthermore, andrographolide attenuated LPS/PA-induced mtROS generation by first promoting autophagic flux and catalase activity, and ultimately inhibiting activation of the NLRP3 inflammasome. Our results suggest that the mechanisms by which andrographolide downregulates LPS/PA-induced IL-1[Formula: see text] release in BMDMs involve promoting autophagic flux and catalase activity. Andrographolide may thus be a candidate to prevent obesity- and lipotoxicity-driven chronic inflammatory disease.

Clinical effects of fractional carbon dioxide laser combined with minimally invasive scar release in the treatment of post-acne atrophic scars / 中华烧伤杂志

Objective: To explore the clinical effects of fractional carbon dioxide laser combined with minimally invasive scar release in the treatment of post-acne atrophic scars. Methods: A retrospectively observational study was conducted. From January to June 2021, 60 patients with grade 3 and 4 post-acne atrophic scars who met the inclusion criteria were admitted to the First Affiliated Hospital of Henan University of Traditional Chinese Medicine. According to the adopted treatment methods, 30 patients treated with fractional carbon dioxide laser combined with minimally invasive scar release were included in combined treatment group (19 males and 11 females, aged (26±4) years), and 30 patients treated with fractional carbon dioxide laser alone were included in laser alone group (18 males and 12 females, aged (25±6) years). All the patients received the treatment once every two months, totally 3 times. Before the first treatment and 2 months after the last treatment, the scars were assessed by échelle d'évaluation clinique des cicatrices d'acné (ECCA). In 2 months after the last treatment, the curative effect was evaluated and the total effective rate was calculated according to the ECCA score. The adverse reactions of patients during the treatment were recorded. Data were statistically analyzed with independent sample t test, Wilcoxon rank-sum test, Mann-Whitney U test, chi-square test, and Fisher's exact probability test. Results: Before the first treatment, the ECCA scores of patients in the two groups were similar (P>0.05). In 2 months after the last treatment, the ECCA scores of patients in combined treatment group were significantly lower than those of laser alone group (Z=-2.89, P<0.05). The ECCA scores of patients in combined treatment group and laser alone group in 2 months after the last treatment were both significantly lower than those before the first treatment (with Z values of -4.81 and -4.79, respectively, P<0.05). In 2 months after the last treatment, the treatment in laser alone group cured the scars in 2 patients, and were markedly effective in 13 patients, effective in 7 patients, and ineffective in 8 patients; the treatment in combined treatment group cured the scars in 4 patients, and were markedly effective in 22 patients, effective in 3 patients, and ineffective in one patients. The total effective rate of scar treatment in combined treatment group (96.67%, 29/30) was significantly higher than 73.33% (22/30) in laser alone group (P<0.05). During treatment, in combined treatment group, 3 patients had pain, one patient had redness and swelling, and one patient had pigmentation. In laser alone group, one patient had pain, and 2 patients had pigmentation. No infection occurred in the wounds of all the patients in the two groups. Conclusions: Compared with fractional carbon dioxide laser alone, fractional carbon dioxide laser combined with minimally invasive scar release for post-acne atrophic scars can result in a higher total effective rate, with simple operation and good effect, so it is worthy of clinical application.

Resource and Reimbursement Barriers to Comprehensive Cancer Care Delivery: An Analysis of Association of Community Cancer Centers Survey Data.

PURPOSE: Comprehensive cancer care (CCC) delivery is recommended in guidelines and considered essential for high-quality cancer management. Barriers, such as insufficient reimbursement, prevent consistent access to and delivery of CCC. Association of Community Cancer Centers conducted a national survey to elucidate capacity and barriers to CCC delivery to inform policy and value-based payment reform. METHODS: Survey methodology included item generation with expert review, iterative piloting, and cognitive validity testing. In the final instrument, 27 supportive oncology services were assessed for availability, reasons not offered, and coverage/reimbursement. RESULTS: 204 of 704 member programs completed survey questions. Despite most services being reported as offered, a minority were funded through insurance reimbursement. The services least likely to obtain reimbursement were those that address practical and family/childcare needs (0.7%), caregiver support (1.5%), advanced care directives (1.7%), spiritual services (1.8%), and navigation (2.7%). These findings did not vary by region or practice type. CONCLUSION: There is a lack of sufficient reimbursement, staffing, and budget to provide CCC across the United States. Care models and reimbursement policies must include CCC services to optimize delivery of cancer care.

Dyadic versus individual delivery of a yoga program for family caregivers of glioma patients undergoing radiotherapy: Results of a 3-arm randomized controlled trial.

BACKGROUND: Despite their significant distress, supportive care interventions for caregivers of glioma patients are generally lacking. And, whether caregivers are more likely to benefit from interventions targeting patient-caregiver dyads or caregivers individually is unknown. This pilot randomized controlled trial compared the feasibility and preliminary efficacy of a dyadic yoga (DY) versus an individual caregiver yoga (CY) intervention as a supportive care strategy for family caregivers. METHODS: Patient-caregiver dyads were randomized to a DY, CY or usual care (UC) arm. DY and CY interventions were delivered over 15 sessions. Caregivers completed assessments of their depressive symptoms, quality of life (QOL), and caregiving reactions at baseline, 6 weeks, and 12 weeks, and a subset completed qualitative interviews at 12 weeks. RESULTS: With a consent rate of 63%, 67 dyads were randomized. Attendance in the DY was higher than in the CY group (session means, DY = 12.23, CY = 9.00; p = 0.06). Caregivers (79% female; 78% non-Hispanic White; mean age, 53 years) reported significantly more subjective benefit in the CY arm than in the DY arm (d = 2.1; p < .01), which was consistent with the qualitative assessment. There were medium effect sizes for improved mental QOL (d = 0.46) and financial burden (d = 0.53) in favor of the CY over the UC group. Caregivers in the CY group reported more caregiving esteem (d = 0.56) and less health decline (d = 0.60) than those in the DY group. CONCLUSION: Individual rather than dyadic delivery may be a superior supportive care approach for this vulnerable caregiver population. A larger, adequately powered efficacy trial is warranted.

The pulmonary pharmacokinetics and anti-inflammatory effects after intratracheal and intravenous administration of Chuankezhi injection.

BACKGROUND: Chuankezhi injection (CKZ) is a traditional Chinese medicine for the treatment of respiratory diseases and has been often used off-label as a nebulization therapy. However, little is known about the aerosolization performance and pulmonary fate of the inhaled CKZ. This study aimed to evaluate the aerodynamic characteristics of nebulizer generated aerosols and to compare the properties of pharmacokinetics, lung distribution and anti-inflammation effects of CKZ after intratracheal and intravenous administration. METHODS: The nebulization performance was evaluated in vitro based on the aerodynamic particle size distribution and aerosol output. The concentrations of epimedins A, B, C and icariin, the main active ingredients of CKZ, in plasma, bronchoalveolar lavage fluids (BALF) and lung tissues were measured by LC-MS/MS analysis. The pulmonary anti-inflammatory efficacy were tested using LPS-induced pulmonary inflammation mice model as indicated by the total cells counts, and the levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in BALF. RESULTS: The aerosols of CKZ generated by a commercial nebulizer showed excellent aerodynamic properties and delivery output. Following intratracheal instillation of CKZ, epidemins A, B and C, and icariin, were absorbed into the bloodstream with the mean absorption time varying from 101.8 min to 271.8 min, and their absolute bioavailabilities ranging from 26.4 % to 104 %. The instillation of CKZ increased the lung to plasma concentration ratios by 25.5-718 folds compared to intravenous administration, leading to improved and prolonged local anti-inflammatory effects. CONCLUSION: Nebulization therapy of CKZ could be a promising alternative to the injectable counterpart.

Evaluation of the Efficacy of a Smoking Cessation Intervention for Cervical Cancer Survivors and Women With High-Grade Cervical Dysplasia: Protocol for a Randomized Controlled Trial.

BACKGROUND: The prevalence of smoking among cervical cancer survivors is strikingly high, yet no smoking cessation interventions to date have specifically targeted this population. This paper describes the study design, methods, and data analysis plans for a randomized clinical trial designed to evaluate the efficacy of a theoretically and empirically based Motivation And Problem Solving (MAPS) approach for promoting and facilitating smoking cessation among cervical cancer survivors. MAPS is a comprehensive, dynamic, and holistic intervention that incorporates empirically supported cognitive behavioral and social cognitive theory-based treatment strategies within an overarching motivational framework. MAPS is designed to be appropriate for all smokers regardless of their motivation to change and views motivation as dynamically fluctuating from moment to moment throughout the behavior change process. OBJECTIVE: This 2-group randomized controlled trial compares the efficacy of standard treatment to MAPS in facilitating smoking cessation among women with a history of high-grade cervical dysplasia or cervical cancer. METHODS: Participants (N=202) are current smokers with a history of high-grade cervical dysplasia or cervical cancer recruited nationally and randomly assigned to one of two treatment conditions: (1) standard treatment (ST) or (2) MAPS. ST consists of repeated letters referring participants to their state's tobacco cessation quitline, standard self-help materials, and free nicotine replacement therapy when ready to quit. MAPS has all ST components along with 6 proactive telephone counseling sessions delivered over 12 months. The primary outcome is abstinence from tobacco at 18 months. Secondary outcomes include abstinence over time across all assessment points, abstinence at other individual assessment time points, quit attempts, cigarettes per day, and use of state quitlines. Hypothesized treatment mechanisms and cost-effectiveness will also be evaluated. RESULTS: This study was approved by the institutional review boards at the University of Texas MD Anderson Cancer Center, the University of Oklahoma Health Sciences Center, and Moffitt Cancer Center. Participant enrollment concluded at Moffitt Cancer Center in January 2020, and follow-up data collection was completed in July 2021. Data analysis is ongoing. CONCLUSIONS: This study will yield crucial information regarding the efficacy and cost-effectiveness of a MAPS approach for smoking cessation tailored to the specific needs of women with a history of high-grade cervical dysplasia or cervical cancer. Findings indicating that MAPS has substantially greater efficacy than existing evidence-based tobacco cessation treatments would have tremendous public health significance.

Exploring the mechanism of Jianpi Qushi Huayu Formula in the treatment of chronic glomerulonephritis based on network pharmacology.

This study was to explore the effective components, potential targets, and pathways of Jianpi Qushi Huayu Formula (JQHF) for the treatment of chronic glomerulonephritics (CGN). First, the Chinese Medicine System Pharmacology Database and Analysis Platform (TCMSP), GeneCards, and OMIM databases were used to collect the major active components of JQHF and potential therapeutic targets of CGN. Then, functional enrichment analysis was performed to clarify the mechanisms of the JQHF on CGN. Subsequently, molecular docking was simulated to assess the binding ability of key targets and major active components. Finally, quantitative real-time PCR and western blot were performed for experimental verification of cells in vitro. A total of 55 active ingredients contained and 220 putative identified targets were screened from JQHF, of which 112 overlapped with the targets of CGN and were considered potential therapeutic targets. Then, we found quercetin and kaempferol are two key ingredients of JQHF, which may act on the top 10 screened targets of PPI, affecting CGN through related signal transduction pathways. Subsequently, molecular docking predicted that quercetin and kaempferol bind firm with the top 10 core targets of PPI. Further experiment verified some results and showed that JQHF has protected glomerular mesangial cells from lipopolysaccharide-induced inflammation by inhibiting expressions of IL6, TNF-α, and AKT1, and activating expressions of VEGFA. Based on network pharmacology, we explored the multi-component, multi-target, and multi-pathway characteristics of JQHF in treating CGN, and found that JQHF could act on IL6, TNF-α, VEGFA, and AKT1 to exert the effect of anti-CGN, which provided new ideas and methods for further research on the mechanism of JQHF in treating CGN.

14-Deoxy-11,12-Didehydroandrographolide Ameliorates Glucose Intolerance Enhancing the LKB1/AMPK[Formula: see text]/TBC1D1/GLUT4 Signaling Pathway and Inducing GLUT4 Expression in Myotubes and Skeletal Muscle of Obese Mice.

14-Deoxy-11,12-didehydroandrographolide (deAND), a bioactive component of Andrographis paniculata, has antidiabetic activity. AMP-activated protein kinase (AMPK) regulates glucose transport and ameliorates insulin resistance. The aim of the present study was to investigate whether activation of AMPK is involved in the mechanism by which deAND ameliorates insulin resistance in muscles. deAND amounts up to 40 [Formula: see text]M dose-dependently activated phosphorylation of AMPK[Formula: see text] and TBC1D1 in C2C12 myotubes. In addition, deAND significantly activated phosphorylation of LKB1 at 6 h after treatment, and this activation was maintained up to 48 h. deAND increased glucose uptake at 18 h after treatment, and this increase was time dependent up to 72 h. Compound C, an inhibitor of AMPK, suppressed deAND-induced phosphorylation of AMPK[Formula: see text] and TBC1D1 and reversed the effect on glucose uptake. In addition, the expression of GLUT4 mRNA and protein in C2C12 myotubes was up-regulated by deAND in a time-dependent manner. Promotion of GLUT4 gene transcription was verified by a pGL3-GLUT4 (837 bp) reporter assay. deAND also increased the nuclear translocation of MEF-2A and PPAR[Formula: see text]. After 16 weeks of feeding, the high-fat diet (HFD) inhibited phosphorylation of AMPK[Formula: see text] and TBC1D1 in skeletal muscle of obese C57BL/6JNarl mice, and deactivation of AMPK[Formula: see text] and TBC1D1 by the HFD was abolished by deAND supplementation. Supplementation with deAND significantly promoted membrane translocation of GLUT4 compared with the HFD group. Supplementation also significantly increased GLUT4 mRNA and protein expression in skeletal muscle compared with the HFD group. The hypoglycemic effects of deAND are likely associated with activation of the LKB1/AMPK[Formula: see text]/TBC1D1/GLUT4 signaling pathway and stimulation of MEF-2A- and PPAR[Formula: see text]-dependent GLUT4 gene expression, which account for the glucose uptake into skeletal muscle and lower blood glucose levels.
