Abstract Introduction: nutritional status and platelet-to-lymphocyte ratio (PLR) have been found to be associated with prognosis in patients with hepatocellular carcinoma (HCC) undergoing transcatheter arterial chemoembolization (TACE). Objectives: to evaluate the association between nutritional status and PLR in patients with HCC undergoing TACE. Methods: a total of 152 HCC patients received TACE were enrolled. The nutritional status was evaluated by Patient-Generated Subjective Global Assessment (PG-SGA). Patients with PG-SGA A and PG-SGA (B or C) were classified as the well-nourished and malnourished groups. Results: according to the PG-SGA, 130 (85.5 %) patients were malnourished. The median PLR was significantly different between well-nourished and malnourished groups (p = 0.008). A positive correlation was found between PLR and PG-SGA score (r = -0.265, p = 0.001). The optimal PLR cutoff value was 102.165 to predict malnutrition, with a sensitivity of 65.4 %, specificity of 72.7 %, and an area under the curve (AUC) of 0.677 (95 % confidence interval (CI): 0.550-0.804; p = 0.008). A logistic stepwise regression model showed that the PLR was associated with nutritional status in Model 1 without adjustment, as well as if adjusted by age, sex, type of TACE (c-TACE/DEB-TACE) and Child–Pugh stage (odds ratio, 0.190; 95 % CI: 0.062-0.582; p = 0.004). Conclusions: nutritional status measured by PG-SGA was significantly associated with PLR in patients with HCC undergoing TACE.

Resumen Introducción: se ha encontrado que el estado nutricional y el índice plaquetas-linfocitos (PLR) se asocian con el pronóstico en pacientes con carcinoma hepatocelular (CHC) sometidos a quimioembolización transarterial (TACE). Objetivos: evaluar la asociación entre el estado nutricional y la PLR en pacientes con CHC sometidos a TACE. Métodos: se evaluaron 152 pacientes con CHC que recibieron TACE. El estado nutricional fue evaluado por Evaluación Global Subjetiva Generada por el Paciente (PG-SGA). Los pacientes con PG-SGA A y PG-SGA (B o C) se clasificaron como los grupos bien nutridos y desnutridos. Resultados: según la PG-SGA, 130 (85,5 %) pacientes estaban desnutridos. La mediana de PLR fue significativamente diferente entre los grupos bien nutridos y desnutridos (p = 0,008).

Un modelo de regresión logística escalonada mostró que el PLR se asoció con el estado nutricional en el Modelo 1 sin ajuste, así como cuando se ajustó por edad, sexo, tipo de TACE (c-TACE/DEB-TACE) y etapa Child-Pugh (odds ratio, 0,190; IC 95 %: 0,062-0,582; p = 0,004). Conclusiones: el estado nutricional medido por PG-SGA se asoció significativamente con PLR en pacientes con CHC sometidos a TACE.

Abstract Background Stroke is a major global public health problem, affecting 13.7 million people worldwide. Previous studies have found a neuroprotective effect of hypothermia therapy and the efficacy and safety of combined hypothermia and mechanical thrombectomy or thrombolysis in the treatment of ischemic stroke have also attracted attention. Objective In the present research, the authors conducted a meta-analysis to comprehensively assess the safety and efficacy of hypothermia combining mechanical thrombectomy or thrombolysis in the treatment of ischemic stroke. Methods Articles published from January 2001 to May 2022 were searched from Google Scholar, Baidu Scholar and PubMed to evaluate the clinical significance of hypothermia treatment in ischemic stroke. Complications, short-term mortality, and the modified Rankin Scale (mRS) in the full text was extracted. Results 89 publications were selected and 9 among them were included in this study with sample size of 643. All selected studies are in accordance with the inclusion criteria. Forest plot of clinical characteristics was as follows: complications (RR = 1.132, 95% CI 0.942‒1.361, p = 0.186, I2= 37.2%), mortality within 3 months (RR = 1.076, 95% CI 0.694‒1.669, p = 0.744, I2= 0.00%), mRS ≤ 1 at 3 months (RR = 1.138, 95% CI 0.829‒1.563, p = 0.423, I2= 26.0%), mRS ≤ 2 at 3 months (RR = 1.672, 95% CI 1.236‒2.263, p = 0.001, I2=49.6%) and mRS ≤ 3 at 3 months (RR = 1.518, 95% CI 1.128‒2.043, p = 0.006, I2= 0.00%). The funnel plot suggested that there was no significant publication bias in the meta-analysis on complications, mortality within 3 months, mRS ≤ 1 at 3 months and mRS ≤ 2 at 3 months. Conclusion In summary, the results showed that hypothermia treatment was correlated with mRS ≤ 2 at 3 months, but not linked with complications and mortality within 3 months.

Abstract Prediction of the development stage of flat peach is very important to determine the harvest time and guarantee high quality peach fruit. The objective of this study was to predict the development stage of flat peach by applying the SVR model based on characteristic taste attributes changes. Seven development stages were divided into immaturity stage (F1-F5) and maturity stage (F6-F7) according to PIs analysis. Both human sensory evaluation and electronic tongue showed that sourness and bitterness significantly decreased, while sweetness increased during seven development stages (P < 0.05). PCA result revealed that sourness and sweetness attributes had a high correlation between human sensory evaluation and electronic tongue. HCA classified seven development stages as two clusters, which was consistent with the PIs analysis. Seven development stages of flat peach were accurately predicted by the SVR model and the correct rate (CR) was 93.9%. The mean squared error (MSE) of each evaluation index was around 0.14 and the squared correlation coefficient (SCC) was over 0.99, which indicated the model performed well. This study proved that taste attribute could be used as an index combined with the SVR model to accurately predict the development stage of flat peach.

Abstract Spices have long been used in many countries to enhance or modify the flavor of meat and meat products. In general, different cooking treatments of spices can produce significantly different flavor. Jiao-ma chicken (JMC), as a traditional and characteristic cuisine in China, is prepared by boiled chicken seasoned with its exquisite flavor sauce. The delicious flavor of its sauce has won great popularity, and fried chili pepper (Capsicum annuum L.) oil (CPO) and pricklyash peel (Zanthoxylum bungeanum M.) oil (PPO) are its essential ingredients. To investigate the effects of CPO and PPO on the formation of aroma characteristics of JMC, the volatiles of CPO and PPO with and without chicken soup (CS) were analyzed by SPME/GC-MS. A total of 69 and 64 volatiles were identified in semi-finished JMC sauce (CS, CPO, and PPO) and final JMC sauce, respectively. GC-MS results showed that the composition and proportions of volatiles were significantly changed. Adding CPO and PPO to the basic CS generated several terpenes, and caused significant decreases in alcohols, aldehydes, and ketones, resulting in an exquisite spicy flavor of JMC sauce. Combined with GC-O and principal component analysis (PCA) results, it was found that 23 volatiles positively involved in the aroma formation, and might be significantly contributed to the unique flavor of JMC sauces.

Objective: This study investigated the prevalence of generalized anxiety disorder (GAD) in Taiwanese patients with type 2 diabetes mellitus (T2DM). Methods: This retrospective observational study was conducted with a random sample of patients from the entire population of National Health Insurance enrollees during 2000-2010 and used ICD-9-CM diagnostic codes to identify T2DM patients and GAD. The prevalence of GAD was compared between T2DM patients and the general population. Results: Between 2000 and 2010, the prevalence of GAD was significantly greater in the T2DM patients than the general population, while the increase of GAD was higher in the general population (from 0.25 to 0.63%) than among T2DM patients (from 0.81 to 1.03%). In T2DM patients, GAD was associated with female gender, a Charlson Comorbidity Index ≥ 1, diabetes mellitus duration > 9 years, and the following comorbidities: congestive heart failure, peripheral vascular disease, and depressive disorder. The prevalence of GAD among T2DM patients was negatively associated with rapid-acting insulin injection therapy and with the use of metformin and sulfonylureas. Conclusion: Since the prevalence of GAD was greater among T2DM patients than the general population, public health initiatives are needed to prevent and treat GAD in T2DM patients, specifically those with the above mentioned risk factors.

SUMMARY OBJECTIVE To study factors affecting the liver regeneration after hepatectomy METHODS With 3D reconstitution technology, liver regeneration ability of 117 patients was analysed, and relative factors were studied. RESULTS There was no statistically difference between the volume of simulated liver resection and the actual liver resection. All livers had different degrees of regeneration after surgery. Age, gender and blood indicators had no impact on liver regeneration, while surgery time, intraoperative blood loss, blood flow blocking time and different ways of liver resection had a significant impact on liver regeneration; In addition, the patients’ own pathological status, including, hepatitis and liver fibrosis all had a significant impact on liver regeneration. CONCLUSION 3D reconstitution model is a good model to calculate liver volume. Age, gender, blood indicators and biochemistry indicators have no impact on liver regeneration, but surgery indicators and patients’ own pathological status have influence on liver regeneration.

A series of carbon nanotube (CNTs)-supported copper-cobalt catalysts were prepared and investigated in a slurry reactor for their ability to selectively convert syngas into higher carbon number alcohols. The 7.5Cu7.5Co/CNTs catalyst achieved superior selectivity towards the formation of ethanol (30.1%) and C2+ alcohols (57.7%), while the 10Co5Cu/CNTs catalyst exhibited the largest alcohol space-time yield (372.9 mg gcat -1 h-1). However, the pure Cu (15Cu/CNTs) catalyst displayed negligible activity. Cobalt reduction was enhanced in the presence of copper. In addition to the Cu0-Co0 center, Co0-Co2+ also presented dual active sites for higher alcohols synthesis, the Co2+ site could terminate carbon chain growth to produce alcohols. The ratio of Cu/Co considerably influences the metal particle properties-synergistically effecting the active species.

Long non-coding RNAs (lncRNAs) play an important role in the pathogenesis of cardiovascular diseases, especially in myocardial infarction and ischemia/reperfusion (I/R). However, the underlying molecular mechanism remains unclear. In this study, we determined the role and the possible underlying molecular mechanism of lncRNA-ROR in myocardial I/R injury. H9c2 cells and human cardiomyocytes (HCM) were subjected to either hypoxia/reoxygenation (H/R), I/R or normal conditions (normoxia). The expression levels of lncRNA-ROR were detected in serum of myocardial I/R injury patients, H9c2 cells, and HCM by qRT-PCR. Then, levels of lactate dehydrogenase (LDH), malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione peroxidase (GSH-PX) were measured by kits. Cell viability, apoptosis, apoptosis-associated factors, and p38/MAPK pathway were examined by MTT, flow cytometry, and western blot assays. Furthermore, reactive oxygen species (ROS) production was determined by H2DCF-DA and MitoSOX Red probes with flow cytometry. NADPH oxidase activity and NOX2 protein levels were measured by lucigenin chemiluminescence and western blot. Results showed that lncRNA-ROR expression was increased in I/R patients and in H/R treatment of H9c2 cells and HCM. Moreover, lncRNA-ROR significantly promoted H/R-induced myocardial injury via stimulating release of LDH, MDA, SOD, and GSH-PX. Furthermore, lncRNA-ROR decreased cell viability, increased apoptosis, and regulated expression of apoptosis-associated factors. Additionally, lncRNA-ROR increased phosphorylation of p38 and ERK1/2 expression and inhibition of p38/MAPK, and rescued lncRNA-ROR-induced cell injury in H9c2 cells and HCM. ROS production, NADPH oxidase activity, and NOX2 protein levels were promoted by lncRNA-ROR. These data suggested that lncRNA-ROR acted as a therapeutic agent for the treatment of myocardial I/R injury.

The mortality of patients with mycotic aneurysms is high, especially in East Asia, and infection by Salmonella species is the most common. Our study aimed to improve prognosis of adult mycotic aneurysms with early diagnosis and accurate treatment. Four adult patients with mycotic aneurysm caused by Salmonella were included and analyzed by single-center retrospective analysis. Cases reported in the literature during the past 10 years were also summarized. The average age of the 4 male patients was 61.25 years, while that of the 53 cases reported in the literature was 65.13 years. Hypertension, diabetes, and atherosclerosis were common complications. Most patients presented fever and experienced pain at the corresponding position of the aneurysm. Laboratory examination found an increased number of white blood cells accompanied by an increase in inflammatory markers. Most aneurysms were found in the abdominal aorta, while the rupture of an aneurysm was the most common complication. The mortality rates were 21.43 and 7.14% after open surgery or endovascular aneurysm repair (EVAR) intervention, respectively. The recurrence rates of infection were 0 and 17.85% for both treatments, respectively. The mortality rate of mycotic aneurysm caused by Salmonella infection was high in middle-aged males with hypertension, diabetes, and atherosclerosis. The possibility of a Salmonella-infected aneurysm should be considered in these high-risk groups presenting chills, fever, chest, and back pain. Open surgery was superior to EVAR treatment in the clearance of infected foci and the reduction of postoperative recurrence. The recurrence of postoperative infection can be prevented by intravenous antibiotic therapy for 6 weeks post-surgery.

Abstract Dynamic compression behaviors of density-homogeneous and density-graded irregular honeycombs are investigated using cell-based finite element models under a constant-velocity impact scenario. A method based on the cross-sectional engineering stress is developed to obtain the one-dimensional stress distribution along the loading direction in a cellular specimen. The cross-sectional engineering stress is contributed by two parts: the node-transitive stress and the contact-induced stress, which are caused by the nodal force and the contact of cell walls, respectively. It is found that the contact-induced stress is dominant for the significantly enhanced stress behind the shock front. The stress enhancement and the compaction wave propagation can be observed through the stress distributions in honeycombs under high-velocity compression. The single and double compaction wave modes are observed directly from the stress distributions. Theoretical analysis of the compaction wave propagation in the density-graded honeycombs based on the R-PH (rigid-plastic hardening) idealization is carried out and verified by the numerical simulations. It is found that stress distribution in cellular materials and the compaction wave propagation characteristics under dynamic compression can be approximately predicted by the R-PH shock model.

Los parámetros anatómicos acumulados podrían ser de significativo valor para un certero diagnóstico clínico y tratamiento de enfermedades de los sacos lagrimales.

The palladium catalyst supported on agarose-alumina composite and its utilization in the Suzuki reaction have been investigated. The agarose-alumina composite was prepared and modified with organofunctional groups by reacting with the coupling reagent 3-aminopropyltriethoxysilane (APTES) through Al−O−Si bonds. Palladium was efficiently loaded on the composite by the amino groups. The Suzuki coupling reaction can proceed successfully at room temperature under air. High yields of various aryl-aryl products have been obtained. Recycling studies have shown that the catalyst can be easily recovered and reused several times. The yields decreased from 95% to 85% in five cycles.

The aim of this study was to enhance the production of vitamin K2 by using N-methyl-N-nitro-N-nitroso-guanidine (NTG) and low energy ion beam implantation and optimizing the fermentation medium. Mutation resulted in 1.66-fold higher production of vitamin K2 than that of the parentl strain. The production by the mutant BN-P15-11-1was increased 55% and reached 3.593±0.107 mg/L by using the Plackett-Burman and Box-Behnken designs to optimize the fermentation medium. The optimal fermentation culture medium was composed of (g/L) glycerol 69.6, sucrose 34.5, K2HPO4 4.0, peptone 20, yeast extract 25 and fermented at 37 °C and 150 rpm for 72 h. The results showed that the NTG and low energy ion beam implantation mutations and optimizing fermentation medium were effective methods to enhance vitamin K2production.
