RESUMO
Unpredicted variability in temperature is associated with frequent extreme low-temperature events. Wheat is a leading crop in fulfilling global food requirements. Climate-driven temperature extremes influence the vegetative and reproductive growth of wheat, followed by a decrease in yield. This review describes how low temperature induces a series of modifications in the morphophysiological, biochemical, and molecular makeup of wheat and how it is perceived. To cope with these modifications, crop plants turn on their cold-tolerance mechanisms, characterized by accumulating soluble carbohydrates, signaling molecules, and cold tolerance gene expressions. The review also discusses the integrated management approaches to enhance the performance of wheat plants against cold stress. In this review, we propose strategies for improving the adaptive capacity of wheat besides alleviating risks of cold anticipated with climate change.
RESUMO
Objective To evaluate the effect of the lactate clearance rate as a guide of the fluid resuscitation in multiple trauma patients with hemorrhage shock .Methods Sixty‐three multiple trauma patients with hemorrhage shock were divided into two groups ,which were group A (32 patients) and group B (31 patients) .In group A ,the central venous pressure (CVP) between8 and 12 mm Hg ,and the mean arterial pressure (MAP) (65 ± 5) mm Hg served as the goals of the fluid resuscitation .The B group ap‐plied the same goals of the CVP and MAP as group A .In addition ,the calculated lactate clearance rate (≥10% ) was used as the treatment target .The percent of patients reaching resuscitation goals and the ratio of the lactate clearance rate (≥10% ) at 2 hours after surgery ,the volume difference of infusion during the first 24 hours ,the incidences of organ dysfunction ,and the average days in ICU were compared between the two groups .Results The percent of patients reaching resuscitation goals at 2 hours after sur‐gery of group A was significantly higher than that of group B(P0 .05) .The incidence of organ dysfunction of group A was higher than that of group B (P<0 .05) .The average days in ICU of group A were longer than that of group B(P<0 .01) .Conclusion Based on monitoring CVP and MAP ,fluid resuscitation under the guidance of the lactate clearance rate(≥10% )may decrease the incidences of organ dysfunction and the days of patients in ICU .
RESUMO
Objective To study the characteristics and clinical significance of the coronary plaques in patients with benign prostatic hyperplasia (BPH).Methods A total of 91 patients undergoing coronary artery angiography (CAG) were selected and divided into two groups according to with or without BPH,56 cases in BPH group,46 cases in control group.The qualitative and quantitative characteristics of 102 lesions area were analyzed by intravascular ultrosound (IVUS),including external elastic membrane-cross-sectional area (EEM-CSA),minimal lumen area (MLA),plaques area (PA),plaques burden (PB),reference external elastic membrane-cross-sectional area (REEM-CSA),reference minimal lumen area (RMAL),reference plaques area (RPA) and reference plaques burden (RPB).Results IVUS showed a higher rate of area stenosis than did the CAG [(58.2± 7.1)％ vs.(55.9 ± 5.2)％,P＜0.01].BPH group had more soft plaques,eccentric plaques,positive remodeling and less calcified than did the control group (P＜0.05).The MLA and RMAL of BPH group were smaller than those of control group:MAL [(5.61±0.96) mm2 vs.(6.06±0.75) mm2,P＜0.05],RMAL[(9.26±1.05) mm2 vs.(10.02±1.10) mm2,P＜0.05]； while the EEM-CSA,PA,PB,RPA,RPB were larger than those of control group:EEM-CSA[(14.51±1.10)mm2 vs.(13.37±1.02)mm2],PA[(8.90±1.24) mm2 vs.(7.31±1.04) mm2],PB[(61.26±6.53)％ vs.(54.53±5.69)％],RPA[(4.26±1.15) mm2 vs.(3.73±1.33) mm2],RPB [(31.30±8.37) ％ vs.(26.81±8.75) ％,P＜0.05].Conclusions IVUS has a higher value on evaluation of mild to moderate coronary artery stenosis.Evidence of myocardial ischemia in patients with BPH needs further excludeing coronary heart disease.
