Through a comprehensive analysis combining network pharmacology prediction and transcriptomics, this study systematically explained the multi-target mechanism of Cyanotis arachnoidea(CA) Gel in improving melasma. A melasma model was induced in female SD rats by progesterone injection combined with ultraviolet B(UVB) irradiation for 40 consecutive days, while the blank control group was only fed routinely. After successful model establishment, the rats were randomly divided into five groups and administered different doses of CA ethanol extract gel(high, medium, and low doses) or arbutin Gel(positive control), which were applied once daily for 28 consecutive days. Subsequently, the levels of superoxide dismutase(SOD), malondialdehyde(MDA), and tyrosinase(TYR) in the skin, serum, and liver tissues were measured. Hematoxylin-eosin(HE) staining and Masson-Fontana staining were used to observe the pathological changes in the tissues. Network pharmacology combined with transcriptomics was employed to identify core targets and pathways, and the differential gene expression was validated by quantitative real-time PCR(qPCR). Pharmacodynamic experiments showed that CA Gel significantly increased SOD activity and decreased MDA and TYR levels in the skin, serum, and liver of model rats. It also improved epidermal thickening, inflammatory infiltration, collagen loss, and melanin deposition. Network pharmacology analysis showed that CA mainly regulated core targets such as signal transducer and activator of transcription 3(STAT3), epidermal growth factor receptor(EGFR), and interleukin-6(IL-6), and modulated the phosphatidylinositol 3-kinase(PI3K)-protein kinase B(AKT) and interleukin-17(IL-17) signaling pathways. Transcriptomic analysis showed that CA Gel significantly downregulated the gene expression of heat shock protein 90β family member 1(Hsp90b1), heat shock protein 90α family member 1(Hsp90aa1), and the key steroid synthesis enzyme cytochrome P450 family 17 subfamily A member 1(Cyp17a1), while upregulating thioredoxin 1(Txn1). qPCR results confirmed that CA Gel regulated oxidative stress and inflammatory response by inhibiting the IL-17 signaling pathway and steroid hormone synthesis. This study, for the first time, reveals the molecular mechanism of CA Gel in improving melasma through multi-target synergistic regulation of oxidative stress, inflammatory response, and hormone metabolism pathways, providing a scientific basis for the treatment of pigmentation diseases with traditional Chinese medicine.

In most types of erectile dysfunction, particularly in advanced stages, typical pathological features observed are reduced parenchymal cells coupled with increased tissue fibrosis. However, the current treatment methods have shown limited success in reversing these pathologic changes. Recent research has revealed that changes in autophagy levels, along with alterations in apoptosis and fibrosis-related proteins, are linked to the progression of erectile dysfunction, suggesting a significant association. Autophagy, known to significantly affect cell fate and tissue fibrosis, is currently being explored as a potential treatment modality for erectile dysfunction. However, these present studies are still in their nascent stage, and there are limited experimental data available. This review analyzes erectile dysfunction from a pathological perspective. It provides an in-depth overview of how autophagy is involved in the apoptotic processes of smooth muscle and endothelial cells and its role in the fibrotic processes occurring in the cavernosum. This study aimed to develop a theoretical framework for the potential effectiveness of autophagy in preventing and treating erectile dysfunction, thus encouraging further investigation among researchers in this area.

OBJECTIVES: To investigate the clinicopathological characteristics and prognostic factors of pediatric Hodgkin lymphoma (HL). METHODS: A retrospective analysis was conducted on the clinical data of children with newly diagnosed HL from January 2011 to December 2023 at four hospitals: Fujian Medical University Union Hospital, Fujian Medical University Zhangzhou Hospital, First Affiliated Hospital of Xiamen University, and Fujian Children's Hospital. Patients were categorized into low-risk (R1), intermediate-risk (R2), and high-risk (R3) groups based on HL staging and pre-treatment risk factors. The patients received ABVD regimen or Chinese Pediatric HL-2013 regimen chemotherapy. Early treatment response and long-term efficacy were assessed, and prognostic factors were analyzed using the Cox proportional hazards regression model. RESULTS: The overall complete response (CR) rates after 2 and 4 cycles of chemotherapy were 42% and 68%, respectively. Compared with the ABVD regimen group, patients treated with the HL-2013 regimen in the R1 group showed significantly higher CR rates after both 2 and 4 cycles (P<0.05). However, no statistically significant differences in CR rates were observed between the two regimens in the R2 and R3 groups (P>0.05). The 5-year event-free survival (EFS) rate, overall survival rate, and freedom from treatment failure rate were 83%±4%, 97%±2%, and 88%±4%, respectively. Cox analysis indicated that the presence of a large tumor mass at diagnosis and failure to achieve CR after 4 cycles of chemotherapy were independent risk factors for lower EFS rates (P<0.05). CONCLUSIONS Pediatric HL generally has a favorable prognosis. The presence of a large tumor mass at diagnosis and failure to achieve CR after 4 cycles of chemotherapy indicate poor prognosis.

To investigate the protective effects and underlying mechanisms of Qin-Zhu-Liang-Xue decoction (QZLX) in atopic dermatitis (AD) and glucocorticoid resistance, we conducted a single-blinded, randomized controlled clinical trial to evaluate the efficacy and safety of this concoction. Network pharmacology analysis was performed and validated through clinical studies. The efficacy, safety, and mechanism of action of QZLX and glucocorticoid receptor (GR) α recombinant protein were assessed in AD mice induced by 2,4-dinitrofluorobenzene (DNFB). Correlation analysis was performed to determine the clinical relevance of GRα. The trial demonstrated that patients who received QZLX showed considerable improvements in their Scoring Atopic Dermatitis (SCORAD) and Dermatology Life Quality Index (DLQI) scores compared with those who received mizolastine at week 4. Network pharmacological analysis identified GRα as a key target for QZLX in AD treatment. QZLX administration increased the serum GRα expression in AD patients, alleviated AD symptoms in mice, decreased inflammatory cytokine expression, and increased GRα expression without affecting liver or kidney function. In addition, GRα recombinant protein improved AD-like skin lesions in DNFB-induced mice. A negative correlation was observed between GRα expression and clinical parameters, including SCORAD, DLQI, and serum IgE levels. QZLX alleviates AD symptoms through the upregulation of GRα and thus presents a novel therapeutic strategy for the prevention of glucocorticoid resistance in AD management.

BACKGROUND: Spinal cord injury (SCI) survivors often experience constipation, which contributes to a reduced sense of well-being and a lower quality of life. Acupressure offers a non-pharmacological and non-invasive alternative therapy for treating constipation. OBJECTIVE: This study examined the effects of home-based acupressure on constipation and subjective well-being among SCI survivors. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: This randomized controlled trial randomly assigned 80 adults from Hong Kong with SCI to two study groups. Using a video demonstration filmed by a registered traditional Chinese medicine practitioner, the intervention group performed home-based acupressure (self-administered or caregiver-assisted) twice daily, 15 min/session, for 10 consecutive days. The control group performed manual light touching of the abdomen with the same frequency and duration as the intervention group. Both groups received defecation education through a structured booklet. MAIN OUTCOMES MEASURES: The primary outcome was constipation severity. Secondary outcomes included bowel habits, psychological well-being, and quality of life. Focus group interviews were conducted after the intervention to collect subjective feedback from participants. RESULTS: Significant group-by-time interaction effects on constipation severity (P = 0.005) and quality of life (P = 0.001) revealed that home-based acupressure produced better results than the control. These treatment effects persisted at the one-month follow-up and continued to have a large effect size (Cohen's d > 0.8). Compared to the control group, the acupressure group also had improvements in anxiety (Cohen's d = 0.69) and depression (Cohen's d = 0.72) at the end of the intervention period. Three qualitative categories were identified from the focus group interviews: improvements in bowel function and management; reduced psychological distress following relief from constipation; and acceptability of home-based acupressure. CONCLUSION: Acupressure effectively relieves constipation, enhances psychological well-being, and improves quality of life in people with SCI. These data provide novel evidence supporting the use of home-based acupressure as an acceptable and effective therapy for treating constipation after SCI.

Berberine (BBR) is the main pharmacological active ingredient of Coptidis, which has hypoglycemic effect, but its clinical application is limited due to its poor oral bioavailability. Polyphenols, derived from cinnamon, are beneficial for type 2 diabetes mellitus (T2DM). The combination of both may have an additive effect. The aim of this study was to investigate the hypoglycemic effect and mechanism of combined medication in diabetic rats. The modeling rats were randomly divided into 5 groups (berberine group, cinnamon group, combined group, metformin group, diabetic control group) and normal control group. The animal experiments were approved by the Animal Ethics Committee (approval number: HMUIRB2022003). The subjects were given orally, and the control group was given equal volume solvent and body weight was measured weekly. Thirty days after administration, oral glucose tolerance test and insulin sensitivity test were performed, and fasting blood glucose (FBG), glycated serum protein (GSP), and serum insulin (INS) levels were detected; high-throughput sequencing technology was used to detect intestinal microbiota structure; real-time quantitative PCR (RT-qPCR) and Western blot were used to detect G protein-coupled receptor 5 (TGR5) and glucagon-like peptide-1 (GLP-1) expression levels. The results showed that, compared with the diabetic control group, the levels of FBG (P < 0.01) and GSP (P < 0.01) in the combined group were lower, and the insulin resistance was improved, which was better than that in the berberine group. Combined treatment increased the relative abundance of Bacteroides, Prevotella and Lactobacillus, reversed the decrease in Lactobacillus in the berberine alone induction group, and the combination of the two could promote the expression of TGR5 and GLP-1. In summary, the combined application of cinnamon and berberine can regulate glucose metabolism better than the application of berberine alone. Berberine combined with cinnamon can improve the function of pancreatic islet β cells in diabetes mellitus type 2 rats by changing the intestinal microbiota, increasing the expression of TGR5 and GLP-1 proteins, and thereby better regulating glucose metabolism.

Objective To investigate the effects of remifentanil and dexmedetomidine controlled hypotension on coagulation function,cerebral oxygen metabolism and amino acid neurotransmitter levels in elderly patients undergoing orthopedic surgery.Methods The elderly patients who underwent lower extremity orthopedic surgery were divided into group A(given dexmedetomidine for hypotension),group B(given remifentanil for hypotension)and group C(given remifentanil combined with dexmedetomidine for hypotension)according to different anesthetic drugs.Systolic blood pressure(SBP),diastolic blood pressure(DBP)and heart rate(HR)were compared among the 3 groups.Cerebral oxygen metabolism[arterial oxygen content,(CaO2),oxygen saturation of internal jugular vein(SjvO2),oxygen content of internal jugular vein(CjvO2)],coagulation function[activated partial thromboplastin time(APTT),prothrombin time(PT),thrombin time(TT),plasma fibrinogen(FIB)],amino acid neurotransmitters[glutamic acid(Glu),aspartate(Asp),gamma-aminobutyric acid(GABA)]were compared,and the occurrence of adverse drug reactions during the trial were compared.Results At 12 h after anesthesia,the APTT of group A,group B and group C were(17.26±2.77),(17.37±2.92)and(31.11±4.74)s,respectively.GABA were(18.74±2.71),(19.22±2.60)and(23.37±2.59)mmol·L-1,respectively.3 min after withdrawal,CaO2 in group A,group B and group C were(139.31±9.03),(140.90±8.70)and(131.75±10.11)mL·L-1,respectively;SjvO2 were(63.59±2.23)％,(63.40±2.44)％and(68.82±3.36)％,respectively.The above indexes of group C were compared with those of group A and group B,and the differences were statistically significant(all P＜0.05).The incidence of adverse drug reactions in group A,B and C were 12.82％,27.50％and 7.32％,respectively.The incidence of adverse drug reactions in group C were lower than that in group A and group B(P＜0.05).Conclusion Remifentanil combined with dexmedetomidine for controlled hypotension in elderly orthopedic surgery has better blood pressure control effect,can improve postoperative coagulation function,maintain cerebral oxygen metabolism balance,reduce cognitive function injury and anesthesia adverse drug reactions.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

AIM To establish a two reference substances for determination of multiple components(TRSDMC)method for the simultaneous content determination of neochlorogenic acid,chlorogenic acid,cryptochlorogenic acid,luteolin-7-O-glucuronide,isochlorogenic acid B,isochlorogenic acid A,isochlorogenic acid C,deoxyelephantopin,isodeoxyelephantopin,isoscabertopin and scabertopin in Elephantopus scabre L..METHODS The analysis was performed on a 35℃thermostatic Waters Symmetry C18,Phenomenex C18,Agilent ZORBAX Eclipse Plus C18 columns(4.6 mm×250 mm,5.0 μm),with the mobile phase comprising of acetonitrile and 0.1%phosphoric acid flowing at 1.0 mL/min in a gradient elution manner,and the detection wavelengths were set at 220,326 nm.Chlorogenic acid was used as an internal standard to calculate the relative correction factors of neochlorogenic acid,cryptochlorogenic acid,luteolin-7-O-glucuronide,isochlorogenic acid B,isochlorogenic acid A and isochlorogenic acid C,while isodeoxyelephantopin was used as an internal standard to calculate the relative correction factors of deoxyelephantopin,scabertopin and isoscabertopin,after which the content determination was made.Subsequently,cluster analysis,principal component analysis and orthogonal partial least squares-discriminant analysis were conducted.RESULTS Eleven constituents showed good linear relationships within their own ranges(r≥0.999 0),whose average recoveries were 95.3%-103.4%with the RSDs of 0.32%-3.45%.The result obtained by TRSDMC approximated those obtained by external standard method.Isochlorogenic acid A,isochlorogenic acid C,isochlorogenic acid B,chlorogenic acid,luteolin-7-O-glucuronide and cryptochlorogenic acid were taken as quality differential constituents.CONCLUSION This reliable and stable method can be used for the quality control of E.scabre.

Objective To study and verify the function of de novo interferon regulatory factor(IRF8)frameshift mutation detected in an etiology screening of the cohort of children with recurrent pneumonia at the molecular level.Methods The recombinant overexpression plasmids with wildtype or mutated IRF8 genes were constructed to transiently transfect HEK293T cells,or packed into lentivirus to infect two kinds of immune cell lines.Q-PCR,Western blot,immunofluorescence and other experimental assays were performed to explore the differences of expression and the regulatory effect on downstream genes associated with inflammation.Results The recombinant vectors with wildtype or mutated IRF8 genes were constructed successfully,and the efficiency of transfection by plasmids and infection by packed lentivirus was remarkable as well.Compared with wildtype,the molecular weight of IRF8 variant was slightly increased,while the expression level presents in opposition,even if on transcription level.Moreover,the localization of IRF8 variant was detected in abundance in nucleus rather than cytoplasm,and its inhibition effect was enhanced on the downstream ISRE element in comparison with the wildtype IRF8 protein.Conclusion The de novo frameshift mutation was presumed as gain-of-function(GOF)mutation.
