RESUMO

PURPOSE: To evaluate the efficacy and safety of immune checkpoint inhibitor combination therapy in advanced renal cell carcinoma (RCC). METHODS: We searched PubMed/Embase/Cochrane Library for relevant randomized controlled trials (RCTs). Clinical outcome measures including overall survival (OS), progression-free survival (PFS), objective response rates (ORRs), and adverse events (AEs) were analyzed by Stata 15.1 software. RESULTS: Seven RCTs involving 3461 patients were included. The pooled hazard ratios of OS and PFS for combination therapy were 0.67 (0.53-0.82, p < 0.001) and 0.68 (0.52-0.83, p < 0.001), respectively. Longer OS and PFS for combination therapy was also observed in the PD-L1 expression leve ≥1% group. The pooled odds ratios of ORRs and grade 3 or higher AEs were 2.31 (1.61-3.32, p < 0.001) and 0.94 (0.65-1.37, p = 0.753), respectively. CONCLUSIONS: Immune checkpoint inhibitor combination therapy showed more clinical benefit in the first-line treatment for advanced RCC, with a safety profile.

RESUMO

The design of artificial photocatalytic devices that simulates the ingenious and efficient photosynthetic systems in nature is promising. Herein, a metal-organic cage [Pd6(NPyCzPF)12]12+ (MOC-PC6) integrating 12 organic ligands NPyCzBP and 6 Pd2+ catalytic centers is designed, which is well defined to include organic dye fluorescein (FL) for constructing a supramolecular photochemical molecular device (SPMD) FL@MOC-PC6. Photoinduced electron transfer (PET) between MOC-PC6 and the encapsulated FL has been observed by steady-state and time-resolved emission spectroscopy. FL@MOC-PC6 is successfully heterogenized with TiO2 by a facile sol-gel method to achieve a robust heterogeneous FL@MOC-PC6-TiO2. The close proximity between the Pd2+ catalytic site and FL included in the cage enables PET from the photoexcited FL to Pd2+ sites through a powerful intramolecular pathway. The photocatalytic hydrogen production assessments of the optimized 4 wt % FL@MOC-PC6-TiO2 demonstrate an initial H2 production rate of 2402 µmol g-1 h-1 and a turnover number of 4356 within 40 h, enhanced by 15-fold over that of a homogeneous FL@MOC-PC6. The effect of the MOC content on photocatalytic H2 evolution (PHE) is investigated and the inefficient comparison systems, such as MOC-PC6, MOC-PC6-TiO2, FL-sensitized MOC-PC6/FL-TiO2, and analogue FL/MOC-PC6-TiO2 with free FL, are evaluated. This study provides a creative and distinctive approach for the design and preparation of novel heterogeneous SPMD catalysts based on MOCs.

RESUMO

BACKGROUND: Male fertility impaired by exogenous toxins is a serious worldwide issue threatening the health of the new-born and causing infertility. However, the metabolic connection between toxic exposures and testicular dysfunction remains unclear. RESULTS: In the present study, the metabolic disorder of testicular dysfunction was investigated using triptolide-induced testicular injury in mice. We found that triptolide induced spermine deficiency resulting from disruption of polyamine biosynthesis and uptake in testis, and perturbation of the gut microbiota. Supplementation with exogenous spermine reversed triptolide-induced testicular dysfunction through increasing the expression of genes related to early and late spermatogenic events, as well as increasing the reduced number of offspring. Loss of gut microbiota by antibiotic treatment resulted in depletion of spermine levels in the intestine and potentiation of testicular injury. Testicular dysfunction in triptolide-treated mice was reversed by gut microbial transplantation from untreated mice and supplementation with polyamine-producing Parabacteroides distasonis. The protective effect of spermine during testicular injury was largely dependent on upregulation of heat shock protein 70s (HSP70s) both in vivo and in vitro. CONCLUSIONS: The present study linked alterations in the gut microbiota to testicular dysfunction through disruption of polyamine metabolism. The diversity and dynamics of the gut microbiota may be considered as a therapeutic option to prevent male infertility. Video Abstract.

RESUMO

Aortic dissection (AD) is a catastrophic cardiovascular emergency with a poor prognosis, and little preceding symptoms. Abnormal lipid metabolism is closely related to the pathogenesis of AD. However, comprehensive lipid alterations related to AD pathogenesis remain unclear. Moreover, there is an urgent need for new or better biomarkers for improved risk assessment and surveillance of AD. Therefore, an untargeted lipidomic approach based on ultra-high-performance liquid chromatograph-mass spectrometry was employed to unveil plasma lipidomic alterations and potential biomarkers for AD patients in this study. We found that 278 of 439 identified lipid species were significantly altered in AD patients (n = 35) compared to normal controls (n = 32). Notably, most lipid species, including fatty acids, acylcarnitines, cholesteryl ester, ceramides, hexosylceramides, sphingomyelins, lysophosphatidylcholines, lysophosphatidylethanolamines, phosphatidylcholines, phosphatidylinositols, diacylglycerols, and triacylglycerols with total acyl chain carbon number ≥54 and/or total double bond number ≥4 were decreased, whereas phosphatidylethanolamines and triacylglycerols with total double bond number <4 accumulated in AD patients. Besides, the length and unsaturation of acyl chains in triacylglycerols and unsaturation of 1-acyl chain in phosphatidylethanolamines were decreased in AD patients. Moreover, lysophosphatidylcholines were the lipids with the largest alterations, at the center of correlation networks of lipid alterations, and had excellent performances in identifying AD patients. The area under the curve of 1.0 and accuracy rate of 100% could be easily obtained by lysophosphatidylcholine (20:0/0:0) or its combination with lysophosphatidylcholine (17:0/0:0) or lysophosphatidylcholine (20:1/0:0). This study provides novel and comprehensive plasma lipidomic signatures of AD patients, identifies lysophosphatidylcholines as excellent potential biomarkers, and would be beneficial to the pathogenetic study, risk assessment and timely diagnosis and treatment of AD.

RESUMO

BACKGROUND: Association between tea consumption and incident hypertension remains uncertain. This study conducted to examine the health effects of tea consumption on blood pressure progression and hypertension incidence. METHODS: A population-based cohort of 38,913 Chinese participants without hypertension at baseline were included in the current study. Information on tea consumption was collected through standardized questionnaires. Associations of tea consumption with blood pressure progression and incident hypertension were analyzed using logistic regression models and Cox proportional hazards regression models, respectively. RESULTS: During a median follow-up of 5.9 years, 17,657 individuals had experienced progression to a higher blood pressure stage and 5,935 individuals had developed hypertension. In multivariate analyses, habitual tea drinkers (≥ 3 times/week for at least six months) had a 17% lower risk for blood pressure progression [odds ratio (OR) = 0.83, 95% CI: 0.79-0.88] and a 14% decreased risk for incident hypertension [hazard ratio (HR) = 0.86, 95% CI: 0.80-0.91] compared with non-habitual tea drinkers. Individuals in different baseline blood pressure groups could obtain similar benefit from habitual tea drinking. In terms of tea consumption amount, an inverse, linear dose-response relation between monthly consumption of tea leaves and risk of blood pressure progression was observed, while the risk of incident hypertension did not reduce further after consuming around 100 g of tea leaves per month. CONCLUSIONS: Our study demonstrated that habitual tea consumption could provide preventive effect against blood pressure progression and hypertension incidence.

RESUMO

Theory identifies factors that can undermine the evolutionary stability of mutualisms. However, theory's relevance to mutualism stability in nature is controversial. Detailed comparative studies of parasitic species that are embedded within otherwise mutualistic taxa (e.g., fig pollinator wasps) can identify factors that potentially promote or undermine mutualism stability. We describe results from behavioral, morphological, phylogenetic, and experimental studies of two functionally distinct, but closely related, Eupristina wasp species associated with the monoecious host fig, Ficus microcarpa, in Yunnan Province, China. One (Eupristina verticillata) is a competent pollinator exhibiting morphologies and behaviors consistent with observed seed production. The other (Eupristina sp.) lacks these traits, and dramatically reduces both female and male reproductive success of its host. Furthermore, observations and experiments indicate that individuals of this parasitic species exhibit greater relative fitness than the pollinators, in both indirect competition (individual wasps in separate fig inflorescences) and direct competition (wasps of both species within the same fig). Moreover, phylogenetic analyses suggest that these two Eupristina species are sister taxa. By the strictest definition, the nonpollinating species represents a "cheater" that has descended from a beneficial pollinating mutualist. In sharp contrast to all 15 existing studies of actively pollinated figs and their wasps, the local F. microcarpa exhibit no evidence for host sanctions that effectively reduce the relative fitness of wasps that do not pollinate. We suggest that the lack of sanctions in the local hosts promotes the loss of specialized morphologies and behaviors crucial for pollination and, thereby, the evolution of cheating.

RESUMO

The design of photochemical molecular devices (PMDs) for photocatalytic H2 production from water is a meaningful but challenging subject currently. Herein, a Pd2 L4 type metal-organic cage (denoted as MOC-Q2) is designed as a PMD, which consists of two catalytic centers (Pd2+ ) and four photosensitive ligands (L-2) with four pyridine anchoring groups. Subsequently, the MOC-Q2 is combined with TiO2 to form TiO2 -MOC-Q2 hybrid materials with different MOC-Q2 contents by a facile sol-gel method, which have micro/mesoporous structures and large surface areas. The optimized TiO2 -MOC-Q2 (6.5 wt%) exhibits high H2 production activity (7.9 mmol g-1 h-1 within 5 h) and excellent durability, giving a TON value of 23477 or 11739 (based on MOC-Q2 or Pd moles) after recycling for 7 rounds. By contrast, the pure MOC-Q2 only shows an ordinary photocatalytic H2 production rate (0.84 mmol g-1 h-1 within 5 h) in the homogeneous system. It can be deduced that TiO2 drives the photocatalysis and simultaneously acts as the structure promoter. This study presents a meaningful and distinctive attempt of a new approach for the design and development of MOC-based heterogeneous photocatalysts.

RESUMO

The development of artificial devices that mimic the highly efficient and ingenious photosystems in nature is worthy of in-depth study. A metal-organic cage (MOC) Pd2(M-4)4(BF4)4, denoted as MOC-Q1, integrating four organic photosensitized ligands M-4 and two Pd2+ catalytic centers is designed for a photochemical molecular device (PMD). MOC-Q1 is successfully immobilized on graphitic carbon nitride (g-C3N4) by hydrogen bonds to obtain a robust heterogeneous direct Z-scheme g-C3N4/MOC-Q1 photocatalyst for H2 generation under visible light. The optimized g-C3N4/MOC-Q1 (2 wt %) system shows high hydrogen evolution activity (4495 µmol g-1 h-1 based on the catalyst mass) and exhibits stable performances for 25 h (a turnover number of 19,268 based on MOC-Q1), significantly outperforming pure MOC-Q1, g-C3N4, and comparsion materials Pd/g-C3N4/M-4, which is the highest one of all reported heterogeneous MOC-based photocatalysts under visible irradiation. This enhancement can be ascribed to the synergistic effects of high-efficient electron transfer, extended visible-light response region, and good protective environment for MOC-Q1 arising from an efficient direct Z-scheme heterostructure of g-C3N4/MOC-Q1. This rationally designed and synthesized MOC/g-C3N4-based heterogeneous PMD is expected to have great potential in photocatalytic water splitting.

RESUMO

Microtuning the substrate-binding pocket (SBP) of EHs has emerged as an effective approach to manipulate their enantio- or regio-selectivities and activities towards target substrates. Here, the enantioselectivity (enantiomeric ratio, E) of AuEH2 towards a racemic (rac-) ortho-trifluoromethyl styrene oxide (o-TFMSO) was improved via microtuning its SBP. Based on the analysis on the crystal structure of AuEH2, its specific residues I192, Y216, R322 and L344 lining the SBP in close to the catalytic triad were identified for site-saturation mutagenesis. After screening, five single-site mutants were selected with E values elevated from 8 to 12-25 towards rac-o-TFMSO. To further improve E, four double-site mutants were constructed by combinatorial mutagenesis of AuEH2R322V separately with AuEH2I192V, AuEH2Y216F, AuEH2L344A and AuEH2L344C. Among all the mutants, AuEH2R322V/L344C possessed the largest E of 83 with activity of 67 U/g wet cell. The kinetic resolution of 200 mM rac-o-TFMSO was conducted at 0 °C for 5.5 h using 80 mg/mL wet cells of E. coli/Aueh2R322V/L344C, a transformant expressing AuEH2R322V/L344C, retaining (S)-o-TFMSO with 98.4 % ees and 49.3 % yields. Furthermore, the molecular docking simulation analysis indicated that AuEH2R322V/L344C more enantiopreferentially attacks the terminal carbon (Cß) in the oxirane ring of (R)-o-TFMSO than AuEH2.

RESUMO

PURPOSE: Combination therapies with immune checkpoint blockade demonstrate promising antitumor activity and safety in Non-small Cell Lung Cancer (NSCLC). However, whether the combination therapy is superior to their monotherapies, and which combination regimen is most efficacious remain unknown. This meta-analysis aims to synthesize the current available evidences on the efficacy and safety of combination immunotherapy in patients with NSCLC. METHODS: PubMed, Embase and Cochrane Library were searched. Randomized controlled trials (RCTs) investigating combination therapy with immune checkpoint inhibitors in NSCLC were included. RESULTS: We identified nine RCTs including a total of 5,142 patients. The study showed that the pooled hazard ratios (HRs) of overall survival (OS) and progression-free survival (PFS) for combination therapy were 0.74 (95% CI: 0.63-0.86, p = 0.001) and 0.65 (95% CI: 0.56-0.73, p = 0.004); the pooled odds ratios (ORs) of objective response rates (ORRs) and grade 3 or higher adverse events (AEs) were 1.51 (95% CI: 1.02-1.99, p < 0.001) and 1.30 (95% CI: 1.03-1.57, p = 0.007). Subgroup analysis showed that the OR of grade 3 or higher AEs for immunotherapy plus chemotherapy was higher than that of chemotherapy alone, but did not reach statistical significance (p = 0.061) , and there was PFS and OS benefit for either immunotherapy plus chemotherapy, double agent immunotherapy or immunotherapy plus targeted plus chemotherapy combination regimens. CONCLUSIONS: Combination therapy with immune checkpoint inhibitors showed more clinical benefit for patients with NSCLC, with increased grade 3 or higher AEs, but toxicities were manageable.

RESUMO

OBJECTIVES: Moderate to vigorous physical activity is recommended to prevent hypertension according to the current guidelines. However, the degree to which the total physical activity (TPA) and its changes benefit normotensives and hypertensives is uncertain. We aimed to examine the effects of TPA and its changes on the incidence, progression, and remission of hypertension in the large-scale prospective cohorts. METHODS: A total of 73,077 participants (55,101 normotensives and 17,976 hypertensives) were eligible for TPA analyses. During a mean follow-up of 7.16 years (394,038 person-years), 12,211 hypertension cases were identified. TPA was estimated as metabolic equivalents and categorized into quartiles. Cox proportional hazards regression and multivariable logistic regression were used to estimate associations of TPA and changes in TPA with incident hypertension and progression/remission of hypertension. RESULTS: Compared with the lowest quartile of TPA, normotensives at the third and the highest quartile had a decreased risk of incident hypertension, with hazard ratios (HRs) of 0.86 [95% confidence interval (CI): 0.81-0.91] and 0.81 (95% CI: 0.77-0.86), respectively. Hypertensives at the highest quartile of TPA demonstrated a decreased risk of progression of hypertension [odds ratio (OR) = 0.87, 95% CI: 0.79-0.95], and an increased probability of hypertension remission (OR = 1.17, 95% CI: 1.05-1.29). Moreover, getting active from a sedentary lifestyle during the follow-up period could reduce 25% (HR = 0.75, 95% CI: 0.58-0.96) risk of incident hypertension, whereas those becoming sedentary did not achieve benefit from initially being active. CONCLUSIONS: Our findings indicated that increasing and maintaining TPA levels could benefit normotensives, whereas higher TPA levels were needed to effectively control progression and improve remission of hypertension. Physical activity played undoubtedly an essential role in both primary and secondary prevention of hypertension.

RESUMO

Asian countries are facing an increasing prevalence of metabolic syndrome (MetS), which may aggravate the burden of cardiovascular diseases in this region. MetS is closely associated with ambulatory blood pressure (BP). Patients with MetS, compared to those without, had a twofold higher risk of new-onset office, home, or ambulatory hypertension. Furthermore, the risk of new-onset MetS in patients with white-coat, masked and sustained hypertension was also doubled compared to normotensives. High-risk masked hypertension and blunted nighttime BP dipping are common in patients with MetS, suggesting perfect 24-hour BP control with long-acting antihypertensive drugs and early initiation of combination therapy might be especially important for patients with MetS.

RESUMO

OBJECTIVE: Both pembrolizumab and lenvatinib demonstrate antitumor activity and safety in cancers. However, whether their combination is safer and more effective than monotherapies remains unknown. A systematic review was performed to assess the safety and efficacy of pembrolizumab plus lenvatinib versus their respective monotherapies in solid cancers. METHODS: PubMed, Embase, and Cochrane Library were searched. Forty-two clinical trials with 8155 patients were included. RESULTS: The total ≥grade 3 adverse events (AEs) and objective response rates (ORRs) among pembrolizumab plus lenvatinib and pembrolizumab or lenvatinib monotherapies in solid cancers were 68.0% vs 17.7% vs 68.5% and 40.6% vs 20.8% vs 43.3%, respectively. The most common AEs of pembrolizumab plus lenvatinib were hypertension (20-61.1%), fatigue (12-59.1%), diarrhea (9-51.9%), hypothyroidism (25-47%), and proteinuria (8-17%). Good ORRs for combination therapy were observed in renal cell carcinoma (70%), gastric cancer (69%), melanoma (48%), head and neck squamous cell carcinoma (46%), and endometrial cancer (38-53%), while these rates were reported as 27%, 11.6-22%, 26-37%, 14.6-23%, and 11-14.3% for monotherapies, respectively. Longer median progression-free survival (mPFS) and median overall survival (mOS) were observed for hepatocellular carcinoma (mPFS 9.3 months, mOS 22.0 months), renal cell carcinoma (mPFS 19.8 months), gastric cancer (mPFS 7.1 months, mOS not reached), and endometrial cancer (mPFS 7.4 months, mOS 16.7 months). CONCLUSIONS: Compared with their monotherapies, pembrolizumab plus lenvatinib showed more promising antitumor activity and resulted in higher ORRs and significant survival benefits in the above cancers. Toxicities were manageable, with no unexpected safety issues.

RESUMO

Background: The relationships between dietary intake of soybean products and incident hypertension were still uncertain. This study aimed to illustrate the associations between intake of soybean products with risks of incident hypertension and longitudinal changes of blood pressure in a prospective cohort study. Methods: We included 67, 499 general Chinese adults from the Project of Prediction for Atherosclerosis Cardiovascular Disease Risk in China (China-PAR). Information about soybean products consumption was collected by standardized questionnaires, and study participants were categorized into the ideal (≥ 125 g/day) or non-ideal (< 125 g/day) group. Hazard ratios (HRs) and corresponding 95% confidence intervals (95% CIs) for incident hypertension were calculated using Cox proportional hazard models. Among participants with repeated measures of blood pressure, generalized linear models were used to examine the relationships between soybean products consumption and blood pressure changes. Results: During a median follow-up of 7.4 years, compared with participants who consumed < 125 g of soybean products per day, multivariable adjusted HR for those in the ideal group was 0.73 (0.67-0.80). This inverse association remained robust across most subgroups while significant interactions were tested between soybean products intake and age, sex, urbanization and geographic region (P values for interaction < 0.05). The mean systolic and diastolic blood pressure levels were 1.05 (0.71-1.39) mmHg and 0.44 (0.22-0.66) mmHg lower among participants in the ideal group than those in the non-ideal group. Conclusions: Our study showed that intake of soybean products might reduce the long-term blood pressure levels and hypertension incidence among Chinese population, which has important public health implications for primary prevention of hypertension.

RESUMO

The utilization of solar energy to produce hydrogen from water is showing increased importance and desirability in the field of artificial photosynthesis to produce clean and sustainable fuels. In a typical three-component dye-sensitized semiconductor system for photocatalysis, the dye sensitizer plays an essential role of energy antenna for harvesting visible light and promoting the reduction reaction to generate hydrogen. In recent decades, a lot of attention has focused on metal-free organic sensitizers, which have the advantages of low cost, high molar extinction coefficient, good modifiability and, most importantly, ability to avoid the use of noble metal ions. This Review enumerates the design strategies, specific properties and photocatalytic performances of metal-free sensitizers in the past 30 years and concludes their evolution process. The advantages of different types of metal-free sensitizers are highlighted and the instructively enlightening experiences are systematic summarized.
