RESUMEN

Transcatheter arterial chemoembolization (TACE) combined with tyrosine kinase inhibitors (TKIs) and camrelizumab (collectively: T-T-C) is a novel treatment strategy for unresectable hepatocellular carcinoma (HCC). The present systematic review and meta-analysis aimed to evaluate the efficacy and safety of T-T-C compared with TACE combined with TKIs only (T-T) in the treatment of patients with unresectable HCC. A systematic literature search was conducted on T-T and T-T-C using PubMed, Embase and the Cochrane Library. Data regarding the clinical outcome, including overall survival (OS), progression-free survival (PFS), tumor response and adverse events (AEs), were independently extracted and analyzed by two researchers using standardized protocols. In total, 7 cohort studies, including 1,798 patients (T-T-C, 838; T-T, 960), were included in the meta-analysis. The results of the present study demonstrated that the T-T-C group had significantly prolonged OS [hazard ratio (HR), 0.38; 95% confidence interval (CI), 0.29-0.50; I2=61.5%; P=0.016)] and PFS (HR, 0.37; 95% CI, 0.30-0.46; I2=44.5%; P=0.109), and showed significantly higher objective response rates [risk ratio (RR), 0.82; 95% CI, 0.69-0.96; I2=25.1%; P=0.237)] and slightly higher disease control rates without a significant difference (RR, 0.96; 95% CI, 0.89-1.03; I2=0.0%; P=0.969). In addition, grade 3/4 AEs were more common in the T-T group, including hypertension (RR, 1.15; 95% CI, 0.85-1.56), vomiting or nausea (RR, 0.88; 95% CI, 0.44-1.76) and pain (RR, 0.74; 95% CI, 0.45-1.21); however, these results were not statistically significant. In conclusion, compared with T-T combination therapy, T-T-C demonstrated a notable advantage in terms of OS, PFS, ORR and DCR in patients with unresectable HCC. For manageable AEs, although the results were not statistically significant, the incidence of AEs in the T-T group was higher than that in the T-T-C group in terms of event probability.

RESUMEN

BACKGROUND: Salvage liver transplantation (SLT) is an effective treatment option for recurrent hepatocellular carcinoma (rHCC) following primary curative treatment (CUR). However, its efficacy remains controversial compared to that of CURs, including repeat liver resection (RLR) and local ablation. This meta-analysis compared the efficacy and safety of these procedures. METHODS: A systematic literature search of the PubMed, Embase, Web of Science, and Cochrane Library databases for studies investigating SLT and CUR was performed. Outcome data, including overall and disease-free survival, tumor response, and operative and postoperative outcomes, were independently extracted and analyzed by two authors using a standardized protocol. RESULTS: Fifteen cohort studies comprising 508 and 2050 patients with rHCC, who underwent SLT or CUR, respectively, were included. SLT achieved significantly longer overall survival than both CUR (hazard ratio [HR]: 0.56, 95 % confidence interval [CI]: 0.45-0.68; I2 = 34.6 %, p = 0.105) and RLR (HR: 0.64, 95 % CI: 0.49-0.84; I2 = 0.0 %, p = 0.639). Similar significantly better survival benefits were observed compared with CUR (HR: 0.30, 95 % CI: 0.20-0.45; I2 = 51.1 %, p = 0.038) or RLR (HR: 0.31, 95 % CI: 0.18-0.56; I2 = 65.7 %, p = 0.005) regarding disease-free survival. However, SLT resulted in a longer operative duration and hospital stay, larger amount of blood loss, higher rate of transfusion and postoperative morbidity, and slightly higher postoperative mortality than CUR. CONCLUSION: SLT was associated with better long-term survival than CUR or RLR in patients with rHCC after primary curative treatment.

RESUMEN

Celluloid, the predecessor to plastic, was synthesized in 1869, and due to technological advancements, plastic products appear to be ubiquitous in daily life. The massive production, rampant usage, and inadequate disposal of plastic products have led to severe environmental pollution. Consequently, reducing the employment of plastic has emerged as a pressing concern for governments globally. This review explores microplastics, including their origins, absorption, and harmful effects on the environment and humans. Several methods exist for breaking down plastics, including thermal, mechanical, light, catalytic, and biological processes. Despite these methods, microplastics (MPs, between 1 and 5 mm in size) continue to be produced during degradation. Acknowledging the significant threat that MPs pose to the environment and human health is imperative. This form of pollution is pervasive in the air and food and infiltrates our bodies through ingestion, inhalation, or skin contact. It is essential to assess the potential hazards that MPs can introduce. There is evidence suggesting that MPs may have negative impacts on different areas of human health. These include the respiratory, gastrointestinal, immune, nervous, and reproductive systems, the liver and organs, the skin, and even the placenta and placental barrier. It is encouraging to see that most of the countries have taken steps to regulate plastic particles. These measures aim to reduce plastic usage, which is essential today. At the same time, this review summarizes the degradation mechanism of plastics, their impact on human health, and plastic reduction policies worldwide. It provides valuable information for future research on MPs and regulatory development.

RESUMEN

BACKGROUND: Programmed death-1 inhibitors plus lenvatinib and transarterial chemoembolization (TACE) (P-L-T) is a novel combination strategy. This systematic review and meta-analysis aimed to evaluate the efficacy and safety of P-L-T compared with lenvatinib and TACE (L-T) therapy in patients with unresectable hepatocellular carcinoma. METHODS: A systematic literature search of the PubMed, Embase, Web of Science and Cochrane Library databases for studies investigating P-L-T therapy was performed. Data regarding outcome data, including overall survival (OS), progression-free survival (PFS), tumor response, and adverse events (AEs), were independently extracted by two authors using a standardized protocol. RESULTS: Eight cohort studies comprising 847 patients (P-L-T: 416, L-T: 431) were included in the meta-analysis. The P-L-T group exhibited significantly longer OS (hazard ratio (Page et al.) 0.51 [95% confidence interval (CI) 0.42-0.62]; I2 = 9.8%; p = 0.354] and PFS (HR 0.51 [95% CI 0.43-0.61]; I2 = 0%; p = 0.824), and higher objective response rate (risk ratio [RR] 1.54 [95% CI 1.33-1.78]; I2 = 0%, p = 0.858]) and disease control rate (RR 1.27 [95% CI 1.17-1.38]; I2 = 17.3%; p = 0.467). Grade 3/4 AEs were more prevalent in the P-L-T group, including hypertension (RR 1.91 [95% CI 1.16-3.15]), vomiting or nausea (RR 2.29 [95% CI 1.01-5.19]), and hypothyroidism (RR 12.21 [95% CI 1.63-91.23]). CONCLUSION: Compared with L-T combination therapy, P-L-T demonstrated a significant advantage in terms of OS, PFS, objective response rate, disease control rate, and manageable AEs.

RESUMEN

Integrating hematite nanostructures with efficient layer double hydroxides (LDHs) is highly desirable to improve the photoelectrochemical (PEC) water oxidation performance. Here, an innovative and facile strategy is developed to fabricate the FeTi-LDH overlayer decorated Fe2 O3 /Fe2 TiO5 photoanode via a surface self-transformation induced by the co-treatment of hydrazine and NaOH at room temperature. Electrochemical measurements find that this favorable structure can not only facilitate the charge transfer/separation at the electrode/electrolyte interface but also accelerate the surface water oxidation kinetics. Consequently, the as-obtained Fe2 O3 /Fe2 TiO5 /LDH photoanode exhibits a remarkably increased photocurrent density of 3.54 mA cm-2 at 1.23 V versus reversible hydrogen electrode (RHE) accompanied by an obvious cathodic shift (≈140 mV) in the onset potential. This work opens up a new and effective pathway for the design of high-performance hematite photoanodes toward efficient PEC water oxidation.

RESUMEN

Both collagen fibres and nanohydroxyapatite crystals have anisotropic magnetisation, which allows them to be oriented by a high magnetic field. Highly oriented nanohydroxyapatite/collagen composites were prepared using a high magnetic field combined with in situ synthesis. These highly oriented composites were investigated and compared with conventional composites. The results showed that the collagen fibres in the magnetically induced highly oriented nanohydroxyapatite/collagen composites had a preferred orientation and smaller molecular spacing, while the nanohydroxyapatite crystals were tightly adhered along the collagen fibre surface. The magnetically induced composites exhibited superior resistance to swelling and degradation along with high compressive strength. This artificial composite, with a structure and composition similar to natural bone, represents a new idea for improving materials for vertical or horizontal bone augmentation.

RESUMEN

A stable 3d-4f heterometallic cluster, namely, {Dy4Ni5L10(NO3)4(CO3)4(CH3OH)2}·CH3CN (Dy4Ni5, HL = 8-hydroxyquinoline), has been solvothermally synthesized and structurally characterized. The compound exhibits an interesting structure in which a tetrahedron based on 4f ions interpenetrates with a square pyramid based on 3d ions. Besides, a unique intermolecular interaction was found in Dy4Ni5, giving rise to its high stability not only when it is in the solid state but also when it dissolves in organic solvents. In addition, the magnetic behavior of solid Dy4Ni5 and the magneto-optical activity of the Dy4Ni5 solution were also studied.

RESUMEN

Pueraria thomsonii has long been used in traditional Chinese medicine. Isoflavonoids are the principle pharmacologically active components, which are primarily observed as glycosyl-conjugates and accumulate in P. thomsonii roots. However, the molecular mechanisms underlying the glycosylation processes in (iso)flavonoid biosynthesis have not been thoroughly elucidated. In the current study, an O-glucosyltransferase (PtUGT8) was identified in the medicinal plant P. thomsonii from RNA-seq database. Biochemical assays of the recombinant PtUGT8 showed that it was able to glycosylate chalcone (isoliquiritigenin) at the 4-OH position and glycosylate isoflavones (daidzein, formononetin, and genistein) at the 7-OH or 4'-OH position, exhibiting no enzyme activity to flavonones (liquiritigenin and narigenin) in vitro. The identification of PtUGT8 may provide a useful enzyme catalyst for efficient biotransformation of isoflavones and other natural products for food or pharmacological applications.

RESUMEN

Bile acids (BAs) are a major component of bile salt, which plays a vital role in the metabolism of lipids in humans. Ninety-five percent of bile acids are recycled by the enterohepatic circulation (EHC), and therefore EHC is essential for bile acid homeostasis. There are four transporters that mediate the transmembrane transport of bile acids, each of which plays an important role in the enterohepatic circulation. Gene defects in bile acid transporters can lead to disorders of the enterohepatic circulation, ultimately leading to clinical phenotypes such as metabolic diseases and even death. Bile transporter expression is altered in patients with various metabolic disease states, suggesting that disruption of bile acid transporters may be a pivotal pathological mechanism for the development of metabolism diseases. Thus, many drugs targeting bile acid transporters are being developed. We provide a concise overview of the progress of bile acid transporters research, discuss the relationship between different bile acid transporters and disease development, and summarize the current progress in drug development targeting bile acid transporters.

RESUMEN

PURPOSE: To evaluate the safety and outcomes of primary posterior continuous curvilinear capsulorhexis (PPCCC) combined with phacoemulsification in postvitrectomy eyes. DESIGN: Retrospective case series. METHODS: Twenty-one postvitrectomy eyes of 21 patients with cataract between April 2017 and December 2019 were enrolled. PPCCC through the cornea incision was performed before in-the-bag intraocular lens implantation. All patients were followed up for at least 3 months postoperatively. The outcome measures were corrected distance visual acuity (CDVA), intraocular pressure (IOP), corneal endothelium cell counts (CECC), central macular thickness (CMT), the occurrence of intraoperative or postoperative complications, and the incidence of posterior capsular opacification (PCO). RESULTS: The mean age was 56.14 ± 9.76 years (ranging from 31 to 68). The mean Snellen CDVA was 20/400 preoperatively and improved to 20/67 postoperatively (P < 0.001). No significant differences were found between IOP (P = 0.96) and CMT (P = 0.42) preoperatively and postoperatively. The mean CECC was 2571.8 ± 319.3 cells/mm2 preoperatively and 2498.2 ± 346.3 cells/mm2 postoperatively (P < 0.05). Lens epithelium cells proliferation was confined to the peripheral capsular bag during a mean follow-up of 12.9 ± 10.5 months (ranging from 3 to 28 months). Intraoperative posterior capsule extension occurred in 1 eye (4%), although it did not affect the patient's vision. No serious complications, including retinal detachment or endophthalmitis, were detected in any of the 21 cases. CONCLUSION: PPCCC through cornea incision combined with phacoemulsification may be a safe and practical alternative to prevent PCO in postvitrectomy eyes with cataract.

RESUMEN

The acrosome reaction is a prerequisite for fertilization, and its signaling pathway has been investigated for decades. Regardless of the type of inducers present, the acrosome reaction is ultimately mediated by the elevation of cytosolic calcium. Inositol 1,4,5-trisphosphate-gated calcium channels are important components of the acrosome reaction signaling pathway and have been confirmed by several researchers. In this study, we used a novel permeabilization tool BioPORTER® and first demonstrated its effectiveness in spermatozoa. The inositol 1,4,5-trisphosphate type-1 receptor antibody was introduced into spermatozoa by BioPORTER® and significantly reduced the calcium influx and acrosome reaction induced by progesterone, solubilized zona pellucida, and the calcium ionophore A23187. This finding indicates that the inositol 1,4,5-trisphosphate type-1 receptor antibody is a valid inositol 1,4,5-trisphosphate receptor inhibitor and provides evidence of inositol 1,4,5-trisphosphate-gated calcium channel involvement in the acrosome reaction in human spermatozoa. Moreover, we demonstrated that the transfer of 1,4,5-trisphosphate into spermatozoa induced acrosome reactions, which provides more reliable evidence for this process. In addition, by treating the spermatozoa with inositol 1,4,5-trisphosphate/BioPORTER® in the presence or absence of calcium in the culture medium, we showed that the opening of inositol 1,4,5-trisphosphate-gated calcium channels led to extracellular calcium influx. This particular extracellular calcium influx may be the major process of the final step of the acrosome reaction signaling pathway.

RESUMEN

The type and frequency of simple sequence repeats( SSRs) in the genomes was investigated using the DNA sequence data of Pueraria lobata and P. thomsonii. Based on these SSRs,20 pairs of SSR primers were designed and 5 high polymorphism primer pairs were selected to analyze genetic diversity of 9 cultivars of P. thomsonii in Jiangxi province. The results showed that the 5 pairs of primers could generate 16 polymorphic alleles bands. The average polymorphism information content( PIC) of each SSR primer pair was 0. 600 7.According to the genetic similarity coefficients,the 9 cultivars of P. thomsonii can be classified into 6 germplasms. This study established DNA identity cards with 5 pairs of SSR primers for different germplasm resources of P. thomsonii in Jiangxi province,which provided reference information for the selection of fine germplasms of P. thomsonii and the theoretical basis for the study of Dao-di herbs.

RESUMEN

PURPOSE: To evaluate the safety, efficacy, and outcomes of early bicanalicular silicone intubation in the treatment of acute purulent dacryocystitis. METHODS: This prospective interventional case series focused on acute purulent dacryocystitis from February 2010 to March 2014. Of the 21 cases, 16 cases were treated at the Fujian Provincial Hospital, and five cases were treated at the Lianjiang Hospital. Bicanalicular silicone intubation was inserted in the original lacrimal duct within 10 days after abscess decompression by pus aspiration method and systemic antibiotic application. Data collection included demographic profiles, perioperative and postoperative complications, and revision surgery. Resolution of signs and symptoms of acute purulent dacryocystitis, as well as successful anatomical patency assessed by irrigation, was evaluated. Follow-up times were more than 12 months, and ranged from 14 to 63 months. RESULTS: All patients showed remarkable improvement of pain and swelling within 48 hours. Resolution of the erythema and edema was observed within one week after bicanalicular silicone intubation combined with topical antibiotic lavage. No intraoperative and postoperative complications were observed. After initial bicanalicular silicone intubation, anatomical success was observed in 66.7% (14/21) of the patients. Of the remaining seven patients who presented with severe reflux in irrigation, two patients chose re-intubation and five patients underwent standard external dacryocystorhinostomy. All patients had anatomical success at last follow-up. CONCLUSION: Early bicanalicular silicone intubation appears to be a safe, effective, and simple procedure, which offers a reasonable option in the treatment of acute purulent dacryocystitis, especially for those developing and underdeveloped areas.

RESUMEN

Objective:To explore the clinical effect of "Bian Que flying rescue" system for patients with chest pain in pre-hospital care.Methods:160 patients with acute chest pain were randomly divided into observation groups (80 cases) and control group (80 cases). The patients of observation group received the treatment of "Bian Que flying rescue" system and the patients of control group received the routine pre-hospital emergency measures. A series of indicators including the diagnosis time of pre-hospital, the time span between attack and beginning treatment, clinical curative effect, occurrence of complication and hospital stay time were compared and recorded.Results:The diagnosis time of pre-hospital, diagnosis time of intra-hospital and the time between attack and beginning treatment of observation group were significantly shortened, and the differences of these indicators between two groups were significant (t=14.095,t=9.997,t=4.230,P<0.05), respectively. The numbers of the attack of various complication of observation group were significantly reduced, and the differences of cardiac failure, cardiogenic shock, malignant arrhythmia and myocardial infarction between the two groups were statistically significant (x2=10.230,x2=9.141, x2=5.223,x2=5.096,P<0.05).And the prognosis of observation group was significantly enhanced, and the number of die in one week was significantly reduced, and the differences of these indicators between the two groups were significantly(x2=12.172,P<0.05). Besides, the time of hospital stay and the total cost of hospital stay of observation group were, respectively, significantly shortened and decreased, and the left ventricular ejection fraction (LVEF) of observation group was significantly increased.
