RESUMO

Objective: This systematic comparative analysis aimed to assess the efficacy of metformin (MET) versus insulin (INS) in the treatment of gestational diabetes mellitus (GDM), providing valuable insights for future GDM management strategies. Methods: We conducted a comprehensive search of clinical studies related to MET and INS interventions in GDM through online literature databases, applying predefined inclusion and exclusion criteria. The quality of the included studies was rigorously evaluated. Data on fasting plasma glucose (FPG), glycosylated hemoglobin (HbA1c), pregnancy weight gain (PWG), premature delivery rate (PDR), and neonatal outcomes among GDM patients were extracted and analyzed using Review Manager 5.3 software. Results: We identified eleven high-quality studies comprising 8679 participants following careful screening and assessment. Our meta-analysis revealed a significant reduction in the incidence of excessive PWG and neonatal hypoglycemia in the MET treatment group (research group) compared to the INS treatment group (control group) (P < .05). Conclusions: Our findings support the effectiveness and safety of MET in achieving optimal blood glucose control in GDM. These results suggest the potential for broader clinical adoption of MET in GDM management.

RESUMO

CONTEXT: Family caregivers face significant challenges when providing care to individuals with advanced cancer. Spiritual coping strategies may support caregivers in addressing these challenges. OBJECTIVES: We evaluated spiritual coping levels among Chinese family caregivers of patients with advanced cancer and explored associated factors. METHODS: This cross-sectional study recruited 358 family caregivers of patients with advanced cancer. The Spiritual Coping Scale was used to evaluate spiritual coping levels, while various scales, including the Caregiver Reaction Assessment Scale, General Self-Efficacy Scale-Schwarzer, and Perceived Social Support Scale, were used to identify influencing factors. T-tests and analysis of variance were used for group comparisons. Pearson's correlation and multivariate linear regression were used to analyze the associated factors. RESULTS: Chinese family caregivers of patients with advanced cancer had moderate spiritual coping levels. Differences in spiritual coping levels were observed in sex, religion, and the presence or absence of anxiety and depression (p < 0.05). Women and caregivers who identified as religious had higher levels, while those with anxiety or depression had lower levels. Spiritual coping was positively correlated with self-efficacy and spiritual health (p < 0.01). Multiple linear regression analysis revealed that religion, anxiety, depression, self-efficacy, and spiritual health were statistically significant associated factors for spiritual coping scores, explaining 43.3% of the variance in scores (F = 53.769, p < 0.001). CONCLUSION: The spiritual coping of Chinese family caregivers should be considered by health care providers, who should focus on alleviating their anxiety and depression while improving self-efficacy and spiritual health, especially among nonreligious caregivers.

RESUMO

Endo-1,4-ß-galactanase is an indispensable tool for preparing prebiotic ß-galacto-oligosaccharides (ß-GOS) from pectic galactan resources. In the present study, a novel endo-1,4-ß-galactanase (PoßGal53) belonging to glycoside hydrolase family 53 from Penicillium oxalicum sp. 68 was cloned and expressed in Pichia pastoris GS115. Upon purification by affinity chromatography, recombinant PoßGal53 exhibited a single band on SDS-PAGE with a molecular weight of 45.0 kDa. Using potato galactan as substrate, PoßGal53 showed optimal reaction conditions of pH 4.0, 40 °C, and was thermostable, retaining >80 % activity after incubating below 45 °C for 12 h. Significantly, PoßGal53 exhibited relatively conserved substrate specificity for (1 â†’ 4)-ß-D-galactan with an activity of 6244 ± 282 U/mg. In this regard, the enzyme is in effect the most efficient endo-1,4-ß-galactanase identified to date. By using PoßGal53, ß-GOS monomers were prepared from potato galactan and separated using medium pressure liquid chromatography. HPAEC-PAD, MALDI-TOF-MS and ESI-MS/MS analyses demonstrated that these ß-GOS species ranged from 1,4-ß-D-galactobiose to 1,4-ß-D-galactooctaose (DP 2-8) with high purity. This work provides not only a highly active tool for enzymatic degradation of pectic galactan, but an efficient protocol for preparing ß-GOS.

RESUMO

Postherpetic neuralgia (PHN) seriously affects the quality of life of the elderly population. This study aimed to evaluate the efficacy of ozonated autohemotherapy (O3-AHT) combined with pulsed radiofrequency (PRF) in the treatment of thoracic PHN in older adults. The medical records of patients with thoracic PHN aged 65 years and older from June 2018 until March 2021 in Shengli Oilfield Central Hospital were reviewed. They were assigned into two groups: PRF alone (PRF group, n = 107) and PRF combined with O3-AHT (PRF + O3-AHT group, n = 109). Visual Analogue Scale for pain was evaluated at pre-treatment, 1 day, 1, 3 and 6 months after treatment. Quality of life and sleep quality were assessed using Short-Form 36 Health Survey and Athens Insomnia Scale at pre-treatment and 6 months post-treatment, respectively. The median age of patients in the PRF and PRF + O3-AHT groups were 69 (67-73) years and 68 (67-72) years, respectively. The former included 62 females and the latter included 51 females. Compared with pre-treatment, the Visual Analogue Scale scores of two groups declined at post-treatment. Patients in the PRF + O3-AHT group showed obviously lower Visual Analogue Scale scores compared with those in the PRF group at 1, 3, and 6 months after treatment and they had earlier withdrawal time for drugs. However, dizziness, tachycardia, sleepiness, and nausea were presented after combination therapy. These symptoms resolved spontaneously after a period of rest. Additionally, O3-AHT combined with PRF was associated with a significant decrease in the Athens Insomnia Scale score and with a significant improvement in every dimension of the Short-Form 36 Health Survey. To conclude, O3-AHT combined with PRF is an effective way to relieve thoracic PHN in older patients.

RESUMO

Objective: To identify the representative attributes of the five elements of a person with a qualitative methodology and provide the basis for the clinical diagnosis and treatment of "people with the five elements in traditional Chinese medicine (TCM)." Methods: Data collected from the literature review, two sessions of brainstorming of experts with related experience in "people with the five elements in TCM" from October 2020 to December 2020, and six rounds of in-depth interviews with 30 participants who had various attributes of the five elements from March 2021 to October 2021 were analyzed. Triangulation was used in this study, and theming and synthesizing were used to analyze the data. Results: A total of 31 experts and 30 interviewees participated in this study. The median age of the experts and interviewees were 48.0 and 38.5 years, respectively; 51.66% and 54.8% of experts and interviewees, respectively, were men. The descriptors of facial diagrams of "people with the five elements in TCM" were complexion, shape, distribution state of facial bones, convergence trend of facial muscles, and facial expression. A theoretical model of "people with the five elements in TCM" was shaped based on these findings. Conclusion: The study suggests a possibility for bridging the gap between personality and bodily state, identifying an avenue for personality research from the perspective of TCM.

RESUMO

BACKGROUND: Tumor treatment still remains a clinical challenge, requiring the development of biocompatible and efficient anti-tumor nanodrugs. Carbon dots (CDs) has become promising nanomedicines for cancer therapy due to its low cytotoxicity and easy customization. RESULTS: Herein, we introduced a novel type of "green" nanodrug for multi-level cancer therapy utilizing Fe-doped carbon dots (Fe-CDs) derived from iron nutrient supplement. With no requirement for target moieties or external stimuli, the sole intravenous administration of Fe-CDs demonstrated unexpected anti-tumor activity, completely suppressing tumor growth in mice. Continuous administration of Fe-CDs for several weeks showed no toxic effects in vivo, highlighting its exceptional biocompatibility. The as-synthesized Fe-CDs could selectively induce tumor cells apoptosis by BAX/Caspase 9/Caspase 3/PARP signal pathways and activate antitumoral macrophages by inhibiting the IL-10/Arg-1 axis, contributing to its significant tumor immunotherapy effect. Additionally, the epithelial-mesenchymal transition (EMT) process was inhibited under the treatment of Fe-CDs by MAPK/Snail pathways, indicating the capacity of Fe-CDs to inhibit tumor recurrence and metastasis. CONCLUSIONS: A three-level tumor treatment strategy from direct killing to activating immunity to inhibiting metastasis was achieved based on "green" Fe-CDs. Our findings reveal the broad clinical potential of Fe-CDs as a novel candidate for anti-tumor nanodrugs and nanoplatform.

RESUMO

BACKGROUND AND OBJECTIVE: Consensus methods are crucial in developing clinical guidelines. Different methods, such as the Delphi and nominal group techniques, are commonly used, but there is a lack of detailed instructions on how to implement them effectively. The survey aims to explore the opinions and attitudes of the chair, panel and working group on the critical elements of the consensus methods during guideline development. METHODS: We used a cross-sectional design to conduct this study and sent a structured questionnaire to stakeholders, including the chair, panel members, and working group participants, through the popular mobile phone application WeChat.We selected participants using a combination of purposive and snowball sampling. The questionnaire gathered information on demographics, experiences, opinions, and concerns regarding consensus methods and guideline development. RESULTS: The sample comprised 290 participants representing 31 provinces or municipalities. Among them, the most significant number of respondents (n = 107, 36.9%) were from Beijing. Most participants, specifically 211 (72.76%), held senior professional titles, while 186 (64.14%) adhered to ongoing guidelines. The Delphi method was the most commonly used consensus method (n = 132, 42.31%), but the respondents had only a preliminary understanding of it (n = 147, 47.12%). The consensus process also revealed the insufficiency of involving pharmacoeconomists, patients, and nurses. CONCLUSIONS: Consensus methods have to be standardised and used consistently in the guideline development process. The findings of this study offer insights into diverse roles and more effective ways to apply the consensus process during guideline development.

RESUMO

This systematic review and meta-analysis aims to: assess the effectiveness and safety of orally administered Chinese herbal medicines (CHMs) as adjuncts to the post-surgical management of chronic rhinosinusitis (CRS); inform clinicians of the current evidence; identify the best available evidence; and suggest directions for further research. Randomised controlled trials (RCTs) were identified from searches of nine databases plus clinical trial registries. Participants were adults and/or children diagnosed with sinusitis or rhinosinusitis, with or without nasal polyps, who had received surgery. Interventions were CHMs used orally following surgery for CRS as additions to conventional post-surgical management. Controls received conventional post-surgical management without CHMs. Studies reported results for Sino-Nasal Outcome Test (SNOT), visual analogue scales (VAS), Lund-Mackay computed tomography score (LM), Lund-Kennedy endoscopic score (LK), mucociliary transport time (MTT), mucociliary transport rate (MTR), mucociliary clearance (MC) or quality of life (QoL). Twenty-one RCTs were included. All used oral CHMs following functional endoscopic sinus surgery (FESS). The pooled results showed no significant difference between groups for SNOT-20 at the end of treatment (EoT) but there was a significant difference at follow up (FU) in favour of additional CHMs. The VAS for total nasal symptoms (VAS-TNS) showed greater improvements in the CHM groups at EoT and FU. Only FU data were reported for LM which showed greater improvement in the CHM groups. LK showed greater improvements at EoT and FU. The measures of mucociliary transport (MTT, MTR, and MC) each showed significantly greater improvement at EoT in the group that received additional CHMs. No study reported QoL. Adverse events were not serious, but reporting was incomplete. The meta-analyses suggested the addition of oral CHMs to conventional management following FESS may improve recovery. However, most studies were not blinded, and substantial heterogeneity was evident in some meta-analyses. Blinded studies are required to further investigate the roles of oral CHMs in post-surgical recovery. Systematic review registration number: The protocol was registered in PROSPERO (CRD42019119586).

RESUMO

This study presents a novel approach for converting cottonseed hulls (CSHs) into valuable proanthocyanidins (PAs) through deep eutectic solvent (DES)-based ultrasound-assisted extraction (UAE-DES). Response surface methodology (RSM) was applied to optimize and model this process, resulting in maximum yields of 78.58 mg/g. The ideal PA extraction conditions were determined to be a liquid-to-material ratio of 36.25 mL/g, a water content of 33.21%, and an extraction period of 7.4 min. Molecular dynamic simulations (MDS) were performed to study the interactions between the solvent and target chemicals. Increased van der Waals forces and stronger interactions between DES and the target chemical catechin (CA) compared to those observed with methanol or water were observed. Furthermore, the optimized extract exhibited a higher PA content than can be obtained with conventional extraction methods and demonstrated antioxidant activity in vitro. The cottonseed hulls residues (CSRs) remaining after the extraction process can be used to produce activated carbon (ACCSR), which has some capacity to adsorb methylene blue (MB) contaminants. This study offers a reference for the fruitful transformation of waste biomass into high-value products.

RESUMO

Objective: To assess the utility of magnetic resonance imaging (MRI) medical technology in the perioperative management of brain gliomas and its impact on anesthesia and prognosis. Methods: An observational, retrospective comparative study was conducted. We selected 60 patients who underwent glioma resection at our hospital from January 2019 to January 2020. Patients were divided into two groups based on admission order: the experimental group (EG) and the control group (CG), with 30 cases each. Patients in the CG underwent conventional intracranial tumor surgery, while those in the EG underwent supratentorial craniotomy for tumor resection with the assistance of MRI medical technology. We compared perioperative parameters, hemodynamic indices, tumor resection outcomes, postoperative complications, and postoperative physical function between the two groups. Results: Compared to the CG, the EG had significantly longer surgery preparation time, anesthesia time, and surgery time (P < .001). However, there were no significant between-group differences in infusion volume and intraoperative blood loss (P > .05). Postoperative hemodynamic indicators were significantly higher in the EG than in the CG (P < .001), and postoperative tumor volume was markedly smaller in the EG (P < .001). The EG also achieved a significantly larger volume of tumor resection and a higher tumor resection rate (P < .001), a significantly lower total incidence of postoperative complications (P < .05), and notably higher Karnofsky Performance Status (KPS) scores (P < .001). Conclusions: Compared to conventional intracranial tumor surgery, the utilization of MRI medical technology in brain glioma surgery, although it prolongs surgery and anesthesia times, enhances the tumor resection rate, and offers significant advantages in improving the prognosis of patients with brain glioma.

RESUMO

Radix aconiti carmichaeli is a widely used traditional Chinese medicine that has been found to be effective in treating cardiovascular diseases and metabolic disorders. Patients with these diseases often experience a heat generation disorder, which is characterized by chilliness and can worsen the progression of the disease. This study established an in vitro screening model combining the examination of cellular mitochondrial membrane potential and mitochondrial temperature to screen drugs with thermogenic activity. After differentiation and determination of the content of characteristic metabolites of the drug-containing serum blood components, it was found that Fuziline (FZL) is the key thermogenic property in Radix aconiti carmichaeli, responsible for its thermogenic effects with a high relative importance of 33%. Experiments were conducted to evaluate the thermogenic activity of Radix aconiti carmichaeli and FZL in vivo by assessing temperature changes in various organs, including the rectum, liver, and brown adipose tissue. Moreover, the effects of intracellular ß3-adrenergic receptor (ß3-AR) agonistic effects were evaluated using transient ß3-AR transfection and dual-luciferase assay systems. The molecular mechanism by which FZL promotes thermogenesis and improves mitochondrial function was investigated by verifying the ß-adrenergic receptors (ß-AR) downstream signaling pathway. The results suggest that FZL activates ß-AR nonselectively, which in turn activates the downstream cAMP-PKA signaling pathway and leads to an increase in liver glycogenolysis and triglyceride hydrolysis, accompanied by enhancing mitochondrial energy metabolism. Consequently, the liver and brown adipose tissue receive energy to generate heat. In summary, these findings provide insight into the therapeutic application of Radix aconiti carmichaeli for metabolic disorders associated with heat generation disorders.

RESUMO

Acpuncture as a branch of traditional Chinese medicine is popular in China. It can regulate the running of meridian qi to stimulate the ocular nerve activity and increase blood supply. Periocular acupuncture treatment is very frequent, but it can lead to safety hazards that cannot be ignored. For instance, ocular trauma may develop if done improperly, resulting in impaired vision and even blindness. We report a rare case of perforating ocular injury caused by acupuncture.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Gliomas are common malignant intracranial tumors that have worse prognosis and pose a serious threat to human health. The Kangliu pill (KLP) is an innovative herbal compound from Xuanwu Hospital of Capital Medical University that has been clinically used for the treatment of gliomas for more than 40 years, and is one of the few drugs for primary treatment of this disorder. But the fundamental molecular mechanisms and pathways of KLP are not clear. AIM OF THE STUDY: To investigate the therapeutic mechanism of KLP in the treatment of gliomas. MATERIALS AND METHODS: An in situ xenograft model of red fluorescent protein-labeled human glioma cell line (U87-RFP) in BALB/c-nu mouse was established, and the therapeutic effect of KLP on gliomas was assessed by tumor weights and fluorescence areas. A quantitative proteomics approach using tandem mass tags combined with liquid chromatography-tandem mass spectrometry was performed to explore differentially expressed proteins (DEPs) in glioma tissues, and bioinformatics analyses including Gene Ontology analysis, pathway analysis, and network analysis were performed to analyze the proteins involved in the network therapeutic mechanisms responsible for key metabolic pathways. Cytological experiments corroborated the above analysis results. RESULTS: Network pharmacology approach screened 246 bioactive compounds contained in KLP, targeting 724 proteins and 173 potential targets of KLP for glioma treatment. The important targets obtained after visualizing the PPI network were AKT1, INS, GAPDH, SRC, TP53, etc. The KEGG enrichment results showed that 9 proteins were related to cancer, including Pathways in cancer, PI3K/AKT signaling pathway, etc. KLP had antitumor activity in gliomas, which reduced tumor weights and fluorescence areas. A number of DEPs possibly associated with gliomas were identified through quantitative proteomic techniques. Among these DEPs, 50 (25 upregulated and 25 downregulated) were identified that might be associated with KLP action. Bioinformatics showed that these 50 DEPs were mainly focused on focal adhesion, extracellular matrix (ECM)-receptor interactions, and the PI3K-Akt signaling pathway. Cytological experiments revealed that KLP significantly inhibited the proliferation and promoted apoptosis of U87-MG human glioma cells, and its mechanism was through the inhibition of PI3K/AKT signaling pathway. CONCLUSION: Therapeutic effect of KLP was regulation of multiple pathways in the treatment of gliomas. In specific, it interacts through the PI3K-Akt signaling pathway. This work may contribute proteomic insights for further research on the medical treatment of glioma using KLP.

RESUMO

Salt homeostasis is orchestrated by both neural circuits and peripheral endocrine factors. The colon is one of the primary sites for electrolyte absorption, while its potential role in modulating sodium intake remains unclear. Here, we revealed that a gastrointestinal hormone, secretin, is released from colon endocrine cells under body sodium deficiency and is indispensable for inducing salt appetite. As the neural substrate, circulating secretin activates specific receptors in the nucleus of the solitary tracts, which further activates the downstream paraventricular nucleus of the hypothalamus, resulting in enhanced sodium intake. These results demonstrated a previously unrecognized gut-brain pathway for the timely regulation of sodium homeostasis.

RESUMO

Ferroptosis is a non-apoptotic programmed cell death caused by the accumulation of lipid peroxide. System Xc-/glutathione peroxidase 4 (GPX4) axis and iron axis are two main pathways regulating ferroptosis. Simultaneously, multiple pathways are also involved in the ferroptosis regulation. Ferroptosis is an intense area of the current study. With the improvement of the regulatory mechanisms that underlie ferroptosis, a variety of drugs associated with ferroptosis have been discovered and developed for cancer therapy. Among them, traditional drugs were developed initially. Small molecule compounds that regulate ferroptosis signaling pathway and iron complexes that promote the Fenton reaction have become important drugs for inducing ferroptosis. In recent years, the emerging development of nanotechnology has promoted the research of ferroptosis nanodrugs. Iron-based nanomaterials are extensively tested as ferroptosis-inducing agents. Furthermore, nanoscale drug delivery systems offer a suitable scaffold for traditional drug therapies. Traditional drugs and nanodrugs are complementary, each with their own strengths and limitations. This review describes the latest studies on the regulation of ferroptosis in tumor cells and focuses on the entanglement between traditional drugs and nanodrugs. To conclude, the challenges and perspectives in this field are put forward.

RESUMO

This systematic review aims to assess the effects and safety of Chinese herbal medicines (CHMs) in the management of rhinosinusitis (RS); inform clinicians of the current state of the evidence; identify the best available evidence; and suggest further directions for research. Five English and four Chinese language databases, and four clinical trial registries were searched. Eligible studies were randomised controlled trials (RCTs). Participants were diagnosed with RS based on established criteria. Test interventions were CHMs administered orally and/or nasally, excluding injections and displacement techniques. Control interventions included placebos, no additional treatment, and conventional non-invasive treatments including pharmacotherapies and/or nasal irrigation, and/or inhalations. Polyposis and post-surgical recovery were excluded. Outcomes were Sino-Nasal Outcome Test (SNOT), visual analogue scales (VAS), Lund-Mackay computed tomography score (LM), Lund-Kennedy Endoscopic score (LK), Mucociliary transport time (MTT), Mucociliary transport rate (MTR), quality of life and adverse events (AEs). Risk of bias used the Cochrane tool. Meta-analysis in Review Manager 5.4.1 used random effects for mean difference (MD) or risk ratio (RR) with 95% confidence intervals. Heterogeneity was assessed as I2. Thirty-four RCTs were included, 30 of chronic RS (CRS) and four of acute RS (ARS). These enrolled 3,752 participants. Five RCTs blinded participants. For CRS, comparisons with placebo showed greater improvements in the CHM groups for SNOT-20 and VAS-TNS (total nasal symptoms). Blinded comparisons with pharmacotherapies showed no differences between groups in the degree of improvement for SNOT-20, VAS-TNS, and LM, suggesting these CHMs had similar effects, at least in the short term. In ARS, pooled results found improved scores on VAS-TNS and LK suggesting a benefit for combining these CHMs with pharmacotherapies. Limitations included inadequacies in study design and methodological reporting, and insufficient reporting of AEs. Heterogeneity in some pooled results precluded strong conclusions. Further well-designed studies are needed to test whether the results are replicable. Systematic review registration number: PROSPERO (CRD42019119586).

RESUMO

Killing tumor cells efficiently with photothermal therapy remains a huge challenge. In this study, we successfully prepared a novel polymer with photothermal conversion capability via a condensation reaction, and then subjected it to Polyethylene glycol (PEG) modification and ultrasonic nanocrystalline treatment to make it suitable forin vivophotothermal therapy applications. The conjugated polymer demonstrated good biocompatibility and photothermal conversion ability and was shown in cell experiments to be effective in killing tumor cells after laser irradiation. In addition, the conjugated polymer-based photothermal therapy, guided by photoacoustic real-time imaging and mediated by laser irradiation, of a tumor-bearing mouse model could effectively inhibit the growth of tumor tissue and demonstrated goodin vivobiosafety. Thus, photothermal therapy based on the conjugated polymer synthesized in this study provides a new idea and strategy for the treatment of lung cancer.
