Please translate the following sentences from Chinese to English. | 早期肠内营养对高血压性脑出血患者医院获得性肺炎的影响。目的 探讨早期肠内营养(EN)对重症高血压性脑出血患者医院获得性肺炎(HAP)的临床价值.方法 将140例重症高血压性脑出血患者按随机数字表法分成治疗组和对照组,治疗组(70例)术后48 h开始EN支持.对照组(70例)术后第2天开始全胃肠外营养(TPN)支持.观察两组HAP发生率、HAP持续时间、肺部二重感染发生率、呼吸机使用率、呼吸机使用时间以及HAP病死率.结果 治疗组HAP发生率、肺部二重感染发生率、呼吸机使用率分别为30.0%(21/70)、12.9%(9/70)、35.7%(25/70),显著低于对照组的47.1%(33/70)、27.1%(19/70)、47.1%(33/70)(P＜0.05);治疗组HAP持续时间、呼吸机使用时间分别为(6.4±2.3)、(6.4±0.5)d,显著短于对照组的(15.6±2.1)、(11.4±0.3)d(P＜0.01或＜0.05).治疗组HAP病死率(8.6%,6/70)显著低于对照组(18.6%,13/70)(P＜0.05).结论 早期EN不仅能有效降低重症高血压性脑出血患者HAP和肺部二重感染的发生率,还可以降低呼吸机使用率,缩短呼吸机使用时间,最终缩短了HAP的治疗时间,降低了HAP的病死率. | The effect of early enteral nutrition on hospital acquired pneumonia in patients with hypertensive cerebral hemorrhage. Objective To investigate the clinical value of early enteral nutrition (EN) on hospital acquired pneumonia (HAP) in postoperative patients with severe hypertensive cerebral hemorrhage.Methods One hundred and forty postoperative patients with severe hypertensive cerebral hemorrhage were divided into treatment group (70 cases) and controll group (70 cases) by random digits table. The treatment group was given EN from the second day after operation, while the control group was given total parenteral nutrition (TPN). The incidence and duration of HAP,the incidence of superinfection,the percent and duration of mechanical ventilation and the mortality rate of HAP was observed. Results The incidence of HAP, superinfection and using mechanical ventilation in treatment group [30.0% (21/70), 12.9% (9/70),35.7%(25/70)] were significantly lower than those in control group [47.1%(33/70) ,27.1%(19/70) ,47.1%( 33/70 )] (P ＜ 0.05 ). The duration of HAP and using mechanical ventilation in treatment group[(6.4 ± 2.3 ),(6.4 ± 0.5 ) d] were significantly lower than those in control group [( 15.6 ± 2.1 ), ( 11.4 ± 0.3 ) d] (P ＜ 0.01or ＜ 0.05 ). The mortality rate of HAP in treatment group was significantly lower than that in control group [8.6% (6/70) vs. 18.6% (13/70),P ＜0.05]. Conclusion Early EN not only effectively decreases the incidence of HAP and superinfection,but also decreases the incidence of mechanical ventilation, shortens the duration of mechanical ventilation and decreases the mortality rate of HAP. |

Serpentine heat-treated at 550, 900 ℃ was analyzed by X-ray diffraction. The dispersive property of serpentine powder in the lubricating oil was investigated using different dispersants. The wear characteristics of the metal friction pairs were explored by an MM-200 friction and wear tester. Base oil and oil containing two kinds of heat-treated serpentine powder were used as lubricants respectively. The surface topographies and composition of the worn surface of 45 steel rings lubricated with the three kinds of lubricating oil were analyzed by scanning electron microscopy and energy dispersive X-ray analysis spectrometer. The results indicate that the phase transformation of serpentine takes place after heating at 900 ℃. The serpentine powders modified by titanate coupling agent in the lubricant oil possess very good dispersibility. Both of the two kinds of heat-treated serpentine powder in lubricating oil can form protective film on the surface of the worn metals. The mechanism is that the rubbing action of the asperities between the two contact surfaces makes the surface of the powder generate a large number of dangling bonds during the friction. At the same time, an activated surface is formed on the contact metal friction pairs, these make the powder adhere to the worn metal surface. Under the action of shearing stress on the contact surfaces, the serpentine powder is spread on the worn metal surface to form self-repairing film. |

Independently photosensitive retinal ganglion cells (ipRGCs) are the third type of photoreceptor cells besides cones and rod cells, located in the inner retina. They contain melanopsin and have the unique ability to respond to light directly. Pupilary light reflex (PLR) is mainly mediated by ipRGCs. IpRGCs can generate PLR by directly sensing light signals from melanopsin, and can also be activated by signals from rods and cones. Because different photoreceptors play unique roles in PLR, light signals of different intensities and wavelengths can be used to selectively stimulate rods, cones, and melanopsin. Analysis of the generated PLR can indirectly reflect the functions of rods, cones, and ipRGCs containing melanopsin. This method is called chromatic pupillometry. This article reviews the pathways of ipRGCs-mediated PLR, the characteristics of PLR mediated by rod/cone cells and melanopsin, the measurement of chromatic pupillometry and their clinical applications, hoping to provide new ideas for the diagnosis and differential diagnosis of related ophthalmic diseases. |

Objective To observe the effects of ulinastatin on the expressions of tumor necrosis factor-α (TNF-α) in the lung tissues of rats with acute lung injmy induced by phosgene, and to explore the mechanism of ulinastafin in treating acute lung injury. Method Sixty-four clean grade healthy male SD rots were randomly divided(random number) into eight groups with eight in each group. Group A1 in which rats were exposed to air. Group A2 in which rots wereexposed to air and treated with saline. Group A3 in which rats were exposed to air and treated with dexamethasone. Group A4 in which mrs were exposed to air and treated with ulinastatin. Group B1 in which rots were exposed to phosgene without treatment. Group B2 in which rats were exposed to phosgene and treated with saline. Group B3 in which rats were exposed to phosgene and treated with dexamethasone. Group B4 in which rats were exposed to phosgene and treated with ulinastatin. The expressions of TNF-α in the lung tissues were measured by using immunohistocheistry. Lung tissues were observed grossly and under 200-fold light microscope to identify the positive expressions in kytoplasm. Results In group B1 and group B2, the wet weight, dry weight and wet/dry weight ratio og right lower lobe of lung were higher thai those in group A1 and group A4( P <0.01 ), and those in group B4 and group B3 were significantly lower than those in group B1(P<0.01 ), but still higher than those in group A1 and A4(P<0.01). The gross observation suggested that the surfaces of lung tissues in group A1and group A2 were slick and rose pink without congestion, dropsy or infarction; the surfaces of lung tissue in groups B1 and B2 appeared with congestion, dropsy and many petechia. The surfaces of lung tissue in groups B3 and B4 were similar to those in groups B1 and B2. Under the light microscope, the structure, of lungs in groups A1 and A2 were clear without congestion, effusion or inflammatory cell infiltration. In groups B1 and B2, the engorgement of lung capillary vessels, congestion and tiny thrombosis were found and there abundant edematous fluid and inflammatory cell infiltration in lung stroma and alveolus with focal pulmonary atelectasis in some lung tissue section. The tissues in groups B3 and B4 showed congestion, dropsy, tiny thrombosis and inflammatory cell infiltration, but these changes were slighter than those in groups B1 and B2. The expressions of TNF-α in groups B1, B2, B3, and B4 were significantly higher thanthose in groups A1 and A2( P < 0.01 ), but the expressions of TNF-α IN group B4 was lower than that in groups B1 and B2(P<0.01). Conclusions Ulinastatin could lessen the lung injury by reducing the expressions of pro-inflammatory cytokines such as TNF-α. |

For interlayer staggered zones revealed in Baihetan large-scale hydropower station,a preparation method of reconstituted specimens is explored to reflect in-situ stress of these zones with an alternative method of super particle processing.Meanwhile,the pre-consolidation pressure and consolidation time are controlled by the static loading.Based on unconsolidated and undrained triaxial tests on reconstituted specimens from the interlayer staggered zone under either different pre-consolidation pressures or different high confining pressures,in combination with tests of mineral composition analysis and scanning electron microscopy (SEM).The mechanical deformation characteristics of interlayer staggered zones under different pre-consolidation pressures are discussed in detail.Under different confining and pre-consolidation pressures,deviatoric stress-axial strain curves of interlayer staggered zones reconstituted specimens exhibit strain hardening,and the plastic failure shows as the waist-drum shape.Under the same pre-consolidation pressure conditions,the failure stress,deformation modulus and Poisson's ratio increase with the increase of confining pressure,and the expansion effect is highly obvious.However,under the same confining pressure,the failure stress,deformation modulus and Poisson's ratio gradually increase with the increase ofpre-consolidation pressure,while the Poisson's ratio decreases slightly.The cohesion decreases and the internal friction angle increases respectively,with consolidation pressure enhancing.The qualitative and quantitative microstructure analysis further reveal that the plastic deformation of the interlayer staggered zone,as rock materials containning fragments,mainly resulted from particle breakage and directional arrangement under high stress.Therefore,the pre-consolidation pressure is an important factor affecting the characteristics of the interlayer staggered zone. |
