RESUMO
Phyllanthus emblica is a fruit widely consumed in subtropical areas, which is rich in polyphenols and other nutrients. There are increasing evidences that as a daily and nutritious fruit, it may have a positive role in controlling diabetic complications. According to the new study, its mechanisms include enhancing the functioning of insulin, reducing insulin resistance, activating the insulin-signaling pathway, protecting ß-cells, scavenging free radicals, alleviating inflammatory reactions, and reducing the accumulation of advanced glycation end products. Owing to its few side effects, and low price, it should be easily accepted by patients and has potential for preventing diabetes. Taken together, Phyllanthus emblica may be an ideal fruit for controlling diabetic complications. This review highlights the latest findings of the role of Phyllanthus emblica in anti-diabetes and its complications, especially clarifies the molecular mechanism of the chemical components related to this effect, and prospects some existing problems and future research directions.

BACKGROUND: Adrenal vein sampling (AVS) is the preferred method for subtyping patients with primary aldosteronism, while the procedure is technically challenging. This study evaluated the feasibility and effectiveness of a single-catheter approach for AVS. METHODS: A retrospective analysis of 106 consecutive patients who underwent AVS was performed to determine the procedural success and complication rates. Bilateral AVS procedures were performed using a single 5-Fr Tiger catheter with repeated manual reshaping. RESULTS: We successfully advanced the catheter into the bilateral adrenal veins of all patients and reached a 90.6% procedural success rate of AVS. The procedural period was 33.0 ± 8.2 min, the fluoroscopy period was 5.8 ± 1.7 min, and the diagnostic contrast used was 17.3 ± 5.5 ml. Only one patient (0.9%) had a hematoma at the femoral puncture site. No other complications were observed. The operation period gradually shortened as the cumulative number of operations increased. The number of procedures required to overcome the learning curve was about 33 cases. CONCLUSIONS: The single-catheter approach is feasible and effective for AVS. Moreover, this approach required a relatively short learning curve for an inexperienced trainee.

BACKGROUND: Catheter-based renal denervation (RDN) has been introduced to treat resistant hypertension. Although the technology of RDN has been largely improved, denervation of tortuous renal arteries remains challenging. CASE PRESENTATION: This is a case report of a 49-year-old man with drug resistant hypertension. The patient was selected for RDN after ruling out possible causes of secondary hypertension. Computed tomography angiography showed a highly tortuous left renal artery. An Iberis multielectrode ablation catheter failed to reach the target vessel with a regular guiding catheter. A 5-French extension catheter was introduced into the proximal segment of the main left renal artery to provide extra support force, which enabled successful ablation of the highly tortuous left renal artery. His ambulatory blood pressure was significantly decreased at 1 month follow-up. CONCLUSIONS: It is feasible and effective to use a guide extension catheter for denervation of highly tortuous renal arteries. The present study provides a useful method to ablate tortuous and angled renal arteries and branches.

Kiwifruit is moderately sweet and sour and quite popular among consumers; it has been widely planted in some areas of the world. In 2019, the crown gall disease of kiwifruit was discovered in the main kiwifruit-producing area of Guizhou Province, China. This disease can weaken and eventually cause the death of the tree. The phylogeny, morphological and biological characteristics of the bacteria were described, and were related to diseases. The pathogenicity of this species follows the Koch hypothesis, confirming that A. fabacearum is the pathogen of crown gall disease of kiwifruit in China. In this study, Loop-mediated isothermal amplification (LAMP) analysis for genome-specific gene sequences was developed for the specific detection of A. fabacearum. The detection limit of the LAMP method is 5 × 10-7 ng/µL, which has high sensitivity. At the same time, the amplified product is stained with SYBR Green I after the reaction is completed, so that the amplification can be detected with the naked eye. LAMP analysis detected the presence of A. fabacearum in the roots and soil samples of the infected kiwifruit plant. The proposed LAMP detection technology in this study offers the advantages of ease of operation, visibility of results, rapidity, accuracy and high sensitivity, making it suitable for the early diagnosis of crown gall disease of kiwifruit.

Indigo Naturalis( IN) is mainly composed of 10% organic matter and 90% inorganic matter,with a poor wettability and strong hydrophobicity. Indigo,indirubin and effective ingredients are almost insoluble in water. And how it exerts its effect after oral administration still needs to be revealed. For this reason,this study put forward the hypothesis that " Indigo Naturalis forms a slightly soluble calcium carbonate carrier in a strong acid environment of gastric fluid,and organic substances are solubilized in the bile environment of intestinal fluid",and then verified the hypothesis. First,the dissolution apparatus was used to simulate the change process of IN in different digestive fluid,and the effects of low-dose and normal bile on the dissolution of inorganic substances and the release of organic substances were compared. After the surface morphology and element changes of IN in different digestive fluid were observed,it was found that bile is the key to promoting the dissolution of organic and inorganic substances in IN. Furthermore,the rat fever model induced by 2,4-dinitrophenol was used to study the antipyretic effect of IN in normal rats and bile duct ligation rats. It was found that the antipyretic effect of IN on normal rats was better than that of bile duct ligation rats. The above results indicated that after oral administration of IN,the calcium carbonate carrier was transformed into a slightly soluble state in acidic gastric fluid,and a small amount of organic matter was released. When IN entered the intestinal fluid mixed with bile,the carrier dissolved in a large amount,and indigo and indirubin were dissolved in a large amount,so as to absorb the blood and exert the effect. This study has a certain significance for guiding clinical application of IN. For patients with insufficient bile secretion( such as bile duct resection),oral administration with IN may not be effective and shall be paid attention.

As an effective antipyretic medicine,Indigo Naturalis has a long history of application in the field of Chinese medicine.The content of organics,mainly indigo and indirubin,is about 10%. However,the active ingredients and mechanism of its antipyretic effect have not yet been fully elucidated. In view of this,they were investigated in this study with the rectal temperature change as an indicator and 2,4-dinitrophenol-induced fever rats as subjects. The content of PGE2 and c AMP in the hypothalamus and the serum levels of TNF-α,IL-1ß and IL-6 were determined by ELISA. Moreover,the plasma samples of fever rats were analyzed by metabonomics in combination with UPLC-Q-TOF-MS for the exploration of potential biomarkers and the discussion on the antipyretic mechanism of Indigo Naturalis and its active ingredients. The results showed that the rising trend of rectal temperature in rats was suppressed 0. 5 h after the treatment with Indigo Naturalis,organic matter,indigo or indirubin as compared with the rats of model group( P < 0. 05),among which Indigo Naturalis and organic matter had better antipyretic effect. ELISA results showed that organic matter and indigo can inhibit the expression of PGE2 and c AMP( P<0. 01),while Indigo Naturalis and organic matter were effective in curbing the increase in TNF-α( P<0. 05). A total of 21 endogenous metabolites were identified from the plasma samples of the Indigo Naturalis,organic matter,indigo and indirubin groups,which were mainly involved in glycerophospholipid metabolism.

Protocatechuic acid is a natural phenolic acid, which widely exists in our daily diet and herbs. It is also one of the main metabolites of complex polyphenols, such as anthocyanins and proanthocyanins. In recent years, a large number of studies on the pharmacological activities of protocatechuic acid have emerged. Protocatechuic acid has a wide range of pharmacological activities including antioxidant, anti-inflammatory, neuroprotective, antibacterial, antiviral, anticancer, antiosteoporotic, analgesia, antiaging activties; protection from metabolic syndrome; and preservation of liver, kidneys, and reproductive functions. Pharmacokinetic studies showed that the absorption and elimination rate of protocatechuic acid are faster, with glucuronidation and sulfation being the major metabolic pathways. However, protocatechuic acid displays a dual-directional regulatory effect on some pharmacological activities. When the concentration is very high, it can inhibit cell proliferation and reduce survival rate. This review aims to comprehensively summarize the pharmacology, pharmacokinetics, and toxicity of protocatechuic acid with emphasis on its pharmacological activities discovered in recent 5 years, so as to provide more up-to-date and thorough information for the preclinical and clinical research of protocatechuic acid in the future. Moreover, it is hoped that the clinical application of protocatechuic acid can be broadened, giving full play to its characteristics of rich sources, low toxicity and wide pharmacological activites.

Primary open-angle glaucoma (POAG) is a leading cause of irreversible vision loss worldwide, with elevated intraocular pressure (IOP) a major risk factor. Myocilin (MYOC) dominant gain-of-function mutations have been reported in â¼4% of POAG cases. MYOC mutations result in protein misfolding, leading to endoplasmic reticulum (ER) stress in the trabecular meshwork (TM), the tissue that regulates IOP. We use CRISPR-Cas9-mediated genome editing in cultured human TM cells and in a MYOC mouse model of POAG to knock down expression of mutant MYOC, resulting in relief of ER stress. In vivo genome editing results in lower IOP and prevents further glaucomatous damage. Importantly, using an ex vivo human organ culture system, we demonstrate the feasibility of human genome editing in the eye for this important disease.

Background: Arterial pressure volume index (API) and arterial velocity pulse index (AVI) contribute to the development of vascular damage and cardiovascular disease. However, the relationship between common API/AVI trajectories and cardiovascular outcomes in hypertensive patients with heart failure with preserved ejection fraction (HFpEF) is unknown.Methods: A total of 488 consecutive hypertensive patients with HFpEF who repeatedly underwent API/AVI measurements were prospectively examined. We then applied API/AVI measurements into actual clinical practice. Latent mixture modeling was performed to identify API/AVI trajectories. Hazards ratios (HRs) were measured using Cox proportional hazard models.Results: We identified four distinct API/AVI trajectory patterns: low (7.6%), moderate (43.8%), high (28.9%), and very high (19.7%). Compared with the low group, higher API trajectories were associated with increased risk of total cardiovascular events (high group, adjusted HR: 2.91, 95% confidence interval [CI]: 1.97-4.26; very high group, adjusted HR: 2.46, 95%CI: 1.18-3.79). Consistently, higher AVI trajectories were also associated with a higher risk of total cardiovascular events (high group, adjusted HR: 2.58, 95%CI: 1.23-5.47; very high group, adjusted HR: 3.12, 95%CI: 1.83-6.08), compared with the low trajectory group.Conclusion: High API/AVI trajectories are strong predictors of cardiovascular risk in hypertensive patients with HFpEF. Among these patients, measuring API/AVI may improve risk stratification and provide additional information to tailor treatment strategies.

OBJECTIVE: To study the possible immunological mechanism of wheezing attack in children with cytomegalovirus (CMV) infection. METHODS: A total of 25 under-5-year-old children with wheezing following CMV infection were enrolled. The expression of serum regulatory T cells (Treg)/T helper 17 (Th17) cytokines interleukin (IL)-10, IL-6, and IL-17, and peripheral blood lymphocyte subsets were determined. Twenty age-matched healthy children were selected as the control group. RESULTS: The wheezing group had a significantly reduced serum IL-10 level, significantly increased IL-6 and IL-17 levels, significantly reduced levels of natural killer cells, and significantly increased levels of CD8+ T cells and CD19+ B cells, as compared with the control group. CONCLUSIONS: Wheezing children with CMV infection have Treg/Th17 imbalance and cellular immune dysfunction, which may be an important immunological mechanism of the development of wheezing in children after CMV infection.

OBJECTIVE: To analyze the clinical features and laboratory indicators in patients with solid malignant tumor-associated venous thromboembolism (Ta-VTE), and to study the risk factors for Ta-VTE. METHODS: The hospitalized patients with VTE in Guizhou Provincial People's Hospital from January to December 2020 were enrolled, and they were divided into Ta-VTE group and pure VTE group based on the presence or absence of solid malignant tumor. The differences in clinical data and laboratory indicators between the two groups were analyzed, and the indicators with significant differences were included in logistic regression model to analyze the risk factors of Ta-VTE. RESULTS: A total of 288 patients with VTE were included in this study, including 64 cases in Ta-VTE group and 224 cases in pure VTE group, respectively. There were significant differences in the following indexes between the two groups, including the hospitalization time (14.20±15.29 d vs 10.05±6.90 d, t=3.112, P =0.002), pain (35.94% vs 65.18%, χ2=17.554, P =0.000), recent surgery (75.00% vs 37.50%, χ2=28.196, P =0.000), D-dimer [2.8 (0.92, 7.55) µg/ml vs 5.69 (2.25, 13.91) µg/ml, Z=-2.710, P =0.007], PLR[198.59 (139.54, 312.16) vs 149.76 (114.08, 233.66), Z=-2.924, P =0.003] and TBIL[10.90 (7.63, 15.68) µmol/L vs 12.90 (9.33, 18.28) µmol/L, Z=-2.066, P =0.039]. There was no significant difference in the other indicators (P >0.05). The result of multivariate logistic regression analysis showed that elevated PLR (OR =1.003, 95%CI : 1.000-1.006, P =0.027), recent surgery (OR =4.312, 95%CI : 2.093-8.885, P =0.000) and prolonged hospitalization (OR =1.037, 95%CI : 1.002-1.074, P =0.038ï¼were independent risk factors for Ta-VTE. However, pain (OR =0.274, 95%CI : 0.133-0.564, P =0.000) was a protective factor. CONCLUSION: Elevated PLR level, recent surgery and prolonged hospital stay are independent risk factors for Ta-VTE patients, and rational use of these indicators is helpful for the clinical diagnosis and treatment of Ta-VTE patients.

Metallic biomaterials activate tumor ferroptosis by increasing oxidative stress, but their efficacy is severely limited in tumor microenvironment. Although interferon gamma (IFN-γ) can promote tumor ferroptosis sensitivity by inhibiting the antioxidant system and promoting lipid accumulation, this effect limited by the lack of IFN-γ accumulation in tumors. Herein, we report a near-infrared (NIR)-responsive HCuS nanocomposite (HCuS-PE@TSL-tlyp-1) that can stimulate immunogenic cell death (ICD)-mediated IFN-γ secretion through exogenous oxidative stress, thereby achieving cascaded ferrotherapy by mutually reinforcing ferroptosis and systemic immunity. Upon laser irradiation, the dissolution of the thermal coating, and the introduction of Cu ions and piperazine-erastin (PE) simultaneously induce oxidative stress by reactive oxygen species (ROS)/lipid peroxide (LPO) accumulation and deplete cystine-glutamate transporter (xCT)/GSH. The onset of oxidative stress-mediated ferroptosis is thus achieved, and ICD is triggered, significantly promoting cytotoxic T-cell (CTL) infiltration for IFN-γ secretion. Furthermore, IFN-γ induces immunogenic tumor ferroptosis by inhibiting xCT-antioxidant pathways and enhancing the ACSL4-fatty acid recruitment pathway, which further promotes sensitivity to ferroptosis in cells. These HCuS nanocomposites combined with aPD-L1 effectively in inhibiting tumor metastasis and recurrence. Importantly, these cascade ferrotherapy results broadens the application of HCuS biomaterials.

Background: Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease characterized by inflammatory cell infiltration, which can lead to chronic disability, joint destruction and loss of function. At present, the pathogenesis of RA is still unclear. The purpose of this study is to explore the potential biomarkers and immune molecular mechanisms of rheumatoid arthritis through machine learning-assisted bioinformatics analysis, in order to provide reference for the early diagnosis and treatment of RA disease. Methods: RA gene chips were screened from the public gene GEO database, and batch correction of different groups of RA gene chips was performed using Strawberry Perl. DEGs were obtained using the limma package of R software, and functional enrichment analysis such as gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), disease ontology (DO), and gene set (GSEA) were performed. Three machine learning methods, least absolute shrinkage and selection operator regression (LASSO), support vector machine recursive feature elimination (SVM-RFE) and random forest tree (Random Forest), were used to identify potential biomarkers of RA. The validation group data set was used to verify and further confirm its expression and diagnostic value. In addition, CIBERSORT algorithm was used to evaluate the infiltration of immune cells in RA and control samples, and the correlation between confirmed RA diagnostic biomarkers and immune cells was analyzed. Results: Through feature screening, 79 key DEGs were obtained, mainly involving virus response, Parkinson's pathway, dermatitis and cell junction components. A total of 29 hub genes were screened by LASSO regression, 34 hub genes were screened by SVM-RFE, and 39 hub genes were screened by Random Forest. Combined with the three algorithms, a total of 12 hub genes were obtained. Through the expression and diagnostic value verification in the validation group data set, 7 genes that can be used as diagnostic biomarkers for RA were preliminarily confirmed. At the same time, the correlation analysis of immune cells found that γδT cells, CD4+ memory activated T cells, activated dendritic cells and other immune cells were positively correlated with multiple RA diagnostic biomarkers, CD4+ naive T cells, regulatory T cells and other immune cells were negatively correlated with multiple RA diagnostic biomarkers. Conclusions: The results of novel characteristic gene analysis of RA showed that KYNU, EVI2A, CD52, C1QB, BATF, AIM2 and NDC80 had good diagnostic and clinical value for the diagnosis of RA, and were closely related to immune cells. Therefore, these seven DEGs may become new diagnostic markers and immunotherapy markers for RA.
RESUMO
This study aimed to explore whether the combined application of desflurane and dexmedetomidine (Dex) reduces the occurrence of postoperative neurocognitive disorders (PND) in patients. We selected patients in our hospital who underwent surgery under general anesthesia, and divided them into two groups: Dex and desflurane (Dex + Des) and desflurane (Des) groups. The data of patients were collected and the Mini-Mental State Examination (MMSE) score was used to assess cognitive status. The blood cell counts were determined preoperatively and on postoperative days 1, 3, and 6, and the percentage of neutrophils and lymphocytes were also recorded. The statistical methods used were the independent-samples t-test and the χ 2 test. Pearson's correlation was used to analyze the correlation between PND and inflammation. The incidence of PND in the Dex + Des group was lower than that in the Des group. The postoperative MMSE scores in the Dex + Des group were higher than those in the Des group (p = 0.032). The percentage of neutrophils in the Dex + Des group was significantly lower than that in the Des group on the first and third days after surgery (p = 0.007; p = 0.028). The MMSE scores on the first day after surgery were negatively correlated with the multiple changes in white blood counts and the percentage of neutrophils (r = -0.3038 and -0.3330). Dex combined with Des reduced the incidence of PND and reduced the postoperative inflammatory cell counts.
RESUMO
Simultaneous mutations in Janus kinase 2 (JAK2), calreticulin, and myeloproliferative leukemia (MPL) genes are generally not considered for characterizing Philadelphia-negative myeloproliferative neoplasms (MPNs), leading to misdiagnosis. Sanger sequencing and quantitative polymerase chain reaction were used to detect gene mutations in patients with MPN. We retrospectively screened the data of patients with double mutations in our center and from the PubMed database. Two patients tested positive for both JAK2V617F and CALR mutations (2/352 0.57%) in our center, while data of 35 patients from the PubMed database, including 26 patients with essential thrombocythemia (ET), 6 with primary myelofibrosis (PMF), 2 with unexplained thrombosis, and 1 with polycythemia vera were screened for double mutations. Among these mutations, co-mutation of JAKV617F-CALR constituted the majority (80.0%), when compared with JAKV617F-MPL (17.1%) and CALR-MPL (2.9%) mutations. Moreover, patients with concurrent mutational myeloproliferative neoplasm (MPN) were relatively older (P = .010) with significantly higher platelet counts than their counterparts with single gene mutations (P < .001). The occurrence of palpable splenomegaly (P < .001) and leukocyte count (P = .041) were also significantly different between patients with single and simultaneous gene mutations. These 4 risk factors also showed significant test effectiveness in the ET and PMF cohorts (P < .05). In terms of clinical characteristics of patients with ET, those with JAK2V617F-CALR mutation had higher but normal hemoglobin levels (P = .0151) than those carrying JAK2V617F-MPL mutation. From a clinical perspective, patients with multiple mutational MPN are different from those with single gene mutations. The poor treatment response by patients in our center and unfavorable indicators for patients with co-mutations in published literature indicate that customized treatment may be the best choice for patients with MPN carrying co-mutations.

BACKGROUND: To systematically evaluate the clinical efficacy of physical and mental exercise on cognitive performance in middle-aged people with mild cognitive impairment (MCI). METHODS: Computer searches of PubMed, Web of science, Embase, Cochrane Library, China Biomedical Literature Service, Wanfang database, China Knowledge Network, and VIP full-text database of Veep journals were conducted to obtain clinical randomized controlled trials on physical and mental exercise interventions in middle-aged and elderly people with MCI. The literature was screened according to inclusion and exclusion criteria, and the final included literature was subjected to data extraction and risk of bias assessment. Meta-analysis was performed using Review Manager 5.4.1 software, and publication bias test was performed using stata17.0 software. RESULTS: A total of 27 publications with a total of 2565 cases of elderly people with MCI were included. The control group was conventional care, health education, or blank control, and the physical and mental exercise group was exercises including Tai Chi, dance, orthopraxia, and qigong for 30 to 90 minutes each time, 3 to 6 times per week, for a total duration of 8 to 36 weeks. Meta-analysis results showed that Montreal cognitive assessment scores (mean difference [MD] = 2.33, 95% CI [1.55, 3.10], P < .00001), the mini-mental state examination score (MD = 1.73, 95% CI [0.60, 2.86], P = .003), trail making test-A score (MD = -4.00, 95% CI [-6.75, -1.25], P = .004), trail making test-B score (MD = -18.46, 95% CI [-23.87, -13.06], P < .00001), global deterioration scale score (MD = -0.72, 95% CI [-1.09, -0.34], P = .0002), Wechsler Logical Memory Scale score (MD = 2.07, 95% CI [0.03, 4.10], P = .05), berg score (MD = -0.70, 95% CI [0.32, 1.07], P < .0003), cerebrospinal fluid Tau protein level (MD = -166.69, 95% CI [-196.93, -136.45], P < .00001), and cerebrospinal fluid levels of αß1-42 protein (MD = 180.39, 95% CI [134.24, 226.55], P < .00001).

ETHNOPHARMACOLOGICAL RELEVANCE: Traditional Chinese medicine and ethnic medicine together play an important value in the modern medicine system that is different from that of chemical drugs. Chinese medicine and ethnic medicine with hemostatic effect have unique advantages and development potential in the prevention and treatment of clinical hemorrhagic diseases, reflecting multi-component, multi-target and multi-pathway effects. AIM OF THE STUDY: In this paper, the active ingredients related to the hemostatic effect of traditional Chinese medicine and ethnic medicine are taken as the starting point, and the traditional Chinese medicine and ethnic medicine with traditional hemostatic purposes are reviewed, and the existing research progress on the active ingredients and their mechanism of action of these drugs is systematically expounded, aiming to provide theoretical reference for the development of traditional hemostatic drugs, the discovery of hemostatic active ingredients and the research of new hemostatic methods. MATERIALS AND METHODS: Hemostatic chinese medicine and ethnic medicine were collected and summarized from the classic books of Materia Medica, public literature database and doctoral or master's thesis repositories. At the same time, we discussed the classification of various types of hemostatic active ingredients of traditional Chinese medicine and ethnic medicine according to the different mechanisms of hemostasis. RESULTS: A total of 436 traditional Chinese medicine and ethnic medicine with hemostatic effects have been collected, and their hemostatic active ingredients include alkaloids, quinones, flavonoids, phenylpropanoids, organic acids, amino acids, terpenoids, steroids, phenols, tannins, esters, polysaccharides and herbal extracts, etc. These active ingredients accelerate the formation of hemostasis by improving endogenous and exogenous hemostatic pathways mainly through enhancing vascular wall contraction, increasing platelet aggregation, promoting coagulation system activation and inhibiting fibrinolysis. CONCLUSIONS: This article reviews the previous data on various aspects of the hemostatic effect of traditional Chinese medicine and ethnomedicine. Many traditional hemostatic drugs have been discovered and many active ingredients and mechanisms have been reported. However, although there are a large number of drugs with traditional hemostatic effects, there are still few developed and applied. At the same time, the hemostatic components of many drugs still remain in the study of the activity of their total extracts, and the potential link between some drug components achieving hemostatic effects through different mechanisms remains to be elucidated.
