目的探讨青少年抑郁症患者的人格特征与非自杀性自伤行为之间的相关性,以增进对抑郁症患者心理健康风险的理解。方法研究于2021年9月至2023年9月在武汉市精神卫生中心进行,共纳入138例首发中重度青少年抑郁症患者,将患者分为无自伤自杀行为组(n=25)、非自杀性自伤(nSSI)组(n=78)和自杀未遂(sa)组(n=35)。通过汉密尔顿焦虑量表(HAma)、汉密尔顿抑郁量表(HAMD)-24以及其他心理评估工具,收集一般资料和神经质人格得分、负性生活事件、情绪状态、社会心理因素等数据。采用统计学方法进行相关性和回归分析研究人格特征与非自杀性自伤行为之间的关系。结果无自伤自杀行为组、非自杀性自伤行为组和自杀行为组在内外倾向、精神质、神经质和掩饰性等人格特征方面存在显著差异,且非自杀性自伤行为组和自杀行为组的评分普遍高于无自伤自杀行为组(P<0.05);自伤行为评分在这三组中也有显著差异,尤其是自杀行为组评分最高,但在生活事件评分方面则无显著差异;焦虑、抑郁、童年期创伤、应激生活事件和自尊方面的评分在三组间均有显著差异,其中自杀行为组在焦虑、抑郁、童年期创伤和应激生活事件评分上最高,但在自尊评分上最低(P<0.05);内外倾向、精神质、神经质和掩饰性与非自杀性自伤行为显著相关,且多元回归分析结果显示这些因素以及焦虑、抑郁、童年期创伤、应激生活事件和自尊是非自杀性自伤行为的独立影响因素,且内外倾向的最佳预测阈值为-10.5%。结论研究揭示了青少年抑郁症患者人格特征与非自杀性自伤行为之间的相关性。对于临床实践和干预策略,了解这些关系有助于更好地识别高风险群体并提供个性化的心理健康支持。

Yields of rice (Oryza sativa L.) respond to complex interactions between the genotype and the environment;rice has the particularity of being a semi-aquatic crop, and as a result of this, it presents lower adaptation to the limiting water content of soil and is extremely sensitive to stress from drought;therefore, it is the most important limiting factor in rice production. The objective of this study was to research the physiological response of rice genotypes to water stress. The grain yield and its components, leaf area and transpiration efficiency under irrigation (I) and drought (D) were evaluated in eight advanced lines from the nursery of the Latin American Fund for Irrigated Rice (Fondo Latinoamericano para Arroz de Riego, FLAR) and a control variety of rice. The experiment was established in Campeche, in the 2015 autumn-winter cycle. The grain yield and its components, as well as the leaf area were greater under irrigation conditions than under drought. The transpiration from the water stress was reduced and the plants under drought increased their transpiration efficiency. The genotypes P-V 2006 and P-V 2009 were identified, with genealogies FL05392-3P-12-2P-2P-M and FL08224-3P-2-1P-3P-M, respectively, as the most outstanding compared to the rest of the genotypes in the grain yield and its components, leaf area, total root biomass, and transpiration efficiency.

Introduction: given the pharmacological change taking place in Spanish delivery rooms, we designed this study to compare the effectiveness and safety of misoprostol (25 mcg/4h) to 10 mg dinoprostone in its slow-releasing vaginalinsert form to induce at-term labor. Methods: In a prospective cohort study (2013-2015), 401 at-term pregnant women referred for induction (Bishop score ≤ 6), who gave birth at the Rey Juan Carlos Hospital in Móstoles (madrid, Spain), of whom 241 participants were induced with misoprostol and 160 with dinoprostone. Patients were recruited by non-probabilistic sampling of consecutive cases as the inductions in the Obstetrics Block during the study period were indicated. Results: The cesarean section rate was 14% for the misoprostol group and 19% for the dinoprostone group [RR = 1.38 (95%CI: 0.89 - 2.13), p = 0.145]. no differences were found in the vaginal birth rate in ng induction [44% vs. 53%, RR = 1.08 (0.90 - 1.29), p = 0.401], nor in the vaginal birth rate in ng oxytocin or meconium fluid, or for maternal-neonatal complications deriving from the method employed. The percentage of cesarean sections due to failed induction was lower in the misoprostol group (15% vs. 39%, p = 0.028). The time between induction and giving birth was shorter for the dinoprostone group (20 h vs. 23.4 h, p = 0.018). Conclusion: Inducing delivery by low-dose misoprostol offers similar effectiveness and safety to induction by dinoprostone in its slow-releasing vaginal-insert form. However, our sample is limited, and few studies are available on the subject. Further analyses to draw solid conclusions are required.

Hydrogen, serving as a clean, sustainable energy source, may be mainly produced from electrolysis water. Herein, we report cobalt disulphide encapsulated in self-catalyzed carbon nanotubes （S, n-CnTs/ CoS2@Co） serving as a bifunctional catalyst, which exhibits excellent hydrogen evolution reaction perfor-mance （10.0 macm^-2 at 0.112 V, and low Tafel slope for 104.9 mV dec^-1 ） and oxygen evolution reaction performance （10.0 macm^-2 at 1.57 V, and low Tafel slope for 76.1 mV dec^-1）, meanwbile with a strong stability at various current densities. In-depth study reveals that the excellent catalytic properties can be mainly attributed to the increased catalytic sites induced by S, n co-doping, the improved electronic con-ductivity derived from the carbon nanotubes, and Mott-Schottky effect between the metal cobalt and semiconductive cobalt disulfide. notably, when the bifunctional catalysts are applied to overall water splitting, a low potential of 1.633 V at the current density of 10.0 macm^-2 is achieved, which can com-pete with the precious metal catalyst benchmarks in alkaline media, demonstrating its promising prac-ticability in the realistic water splitting application. This work elucidates a practicable way to the design of transition metal and nano-carbon composite catalysts for a broad application in the fields of energy chemistry.

we demonstrate the generation of a Q-switching pulse train in an erbium-doped fiber laser （EDFL） cavity using a newly developed cadmium selenide （CdSe） based saturable absorber （sa）. The sa is obtained by embedding CdSe nanomaterials into a polymethyl methacrylate （PMma） microfiber. It is incorporated into an EDFL cavity to generate a Q-switched laser operating at 1533.6nm. The repetition rates of the produced pulse train are tunable within 37–64kHz as the pump power is varied from 34mw to 74mw. The corresponding pulse width reduces from 7.96μs to 4.84μs, and the maximum pulse energy of 1.16nJ is obtained at the pump power of 74mw.

This study investigated the effects of dietary supplementation of indigenous phytase producing live yeast cultures on growth performance, phytate degradation and blood biochemical parameters of weanling rabbits. Fifty-six rabbits (28 males and 28 females) were allotted randomly into four groups containing a control and three groups administrated each with the yeasts saccharomyces cerevisiae ADR1B1, Hanseniaspora jakobsenii ADR3E1, Hanseniaspora guilliermondii RD31 during 8 weeks. The results showed that the administration of the three yeast strains accelerated the weight gain and improved rabbits growth performance in comparison to the control group, but did not affect the serum biochemical and hematological parameters. The highest weight gain (1715.95 ± 236 g), and phytate degradation rate (73.82% ± 0.92%) and the lowest biochemical parameters (triglycerides, cholesterol, HDL and LDL) were observed on rabbits fed with the yeast Hanseniaspora jakobsenii ADR3E1. This indigenous yeast species, which is used for the first time in animal feeding provided the best beneficial effects in rabbit breeding. Therefore, based on this finding, Hanseniaspora jakobsenii ADR3E1 can be recommended to supplement rabbit diets for growth performance and profitability enhancement.
