Over-fertilization has caused significant phosphorus(P)accumulation in Chinese greenhouse vegetable production(GVP)*** study,for the first time,quantified profile P accumulation directly from soil P measurements,as well as subsoil P immobilization,in three alkaline coarse-textured GVP soil profiles with 5(S5),15(S15),and 30(S30)years of cultivation in Tongshan,Southeast *** each profile,soil samples were collected at depths of 0-10(topsoil),10-20,20-40,40-60,60-80,and 80-100 *** accumulation was estimated from the difference in P contents between topsoil and parent material(60-100 cm subsoil).Phosphorus mobility was assessed from measurements of water-soluble P concentration(P_(Sol)).Finally,P sorption isotherms were produced using a batch sorption experiment and fitted using a modified Langmuir *** total P contents of 1980(S5),3190(S15),and 2330(S30)mg kg^(-1) were measured in the topsoils versus lower total P content of approximately 600 mg kg^(-1) in the 80-100 cm ***,topsoil PSol values were very high,varying from 6.4 to 17.0 mg L^(-1).The estimated annual P accumulations in the topsoils were 397(S5),212(S15),and 78(S30)kg ha^(-1) year^(-1).Sorption isotherms demonstrated the dominance of P desorption in highly P-saturated topsoils,whereas the amount of adsorbed P increased in the 80-100 cm subsoils with slightly larger P adsorption *** total P adsorption capacity of the 80-100 cm subsoils at a solution P concentration of0.5 mg L^(-1) was 15.7(S5),8.7(S15),and 6.5(S30)kg ha^(-1),demonstrating that subsoils were unable to secure P concentrations in leaching water below 0.5 mg L^(-1) because of their insufficient P-binding capacity.

【目的】农田中施用腐秆剂能否有效地促进秸秆腐解和养分释放,进而提高作物产量一直存在争议。在全国尺度上,整合分析腐秆剂田间施用的秸秆促腐和作物增产效果,探明不同气候和土壤状况、秸秆特征以及还田条件下腐秆剂施用对还田秸秆降解和作物产量的影响,为科学合理地使用腐秆剂提供指导。【方法】本研究利用整合分析的方法（meta-analysis）,系统分析了2001—2019年公开发表的腐秆剂田间应用相关研究论文（共89篇,含腐秆剂促腐秸秆数据63条、腐秆剂提高作物产量数据207条）,探讨了气候类型、还田条件、秸秆种类、还田初始碳氮比（C/N）、土壤pH和土壤有机质（SOM）含量等6方面因素对腐秆剂促腐和增产作用的影响。【结果】研究发现,与不施腐秆剂相比,施用腐秆剂总体上可有效促进还田秸秆的降解,但在温带大陆性气候地区,秸秆还田初始C/N≤15以及土壤为中性时,腐秆剂的促腐效应却不显著,效应值的范围分别为-0.010—0.716、-0.302—0.568和-1.01—0.475;还田条件、秸秆种类和SOM含量会显著影响腐秆剂的促腐作用强度。类似地,腐秆剂的田间施用对作物产量的作用总体也表现为显著提升,但在土壤为中性时腐秆剂的增产作用并不稳定,其效应值范围为-0.284—0.751;除了还田环境、SOM含量外,其余4方面因素均会显著改变腐秆剂的增产幅度。此外,线性拟合结果显示秸秆促腐率与作物增产率之间呈现显著正相关关系（R2=0.307,P<0.0001）。【结论】施用腐秆剂可有效促进秸秆腐解和增加作物产量,且在温带季风性气候条件下,将玉米秸秆于旱地条件下还田,在还田初始C/N大于30以及土壤呈酸或碱性时配施腐秆剂效果最佳。

Prostate cancer affects over 200000 men annually in the United States *** role of conventionally fractionated external beam radiation therapy (RT) is well established as a treatment option for eligible prostate cancer patients; however,the use of stereotactic body radiotherapy (SBRT) in this setting is less well *** the past decade,there have been a number of studies investigating the feasibility of SBRT as a potential treatment option for prostate cancer *** has been well studied in other disease sites,and the shortened treatment course would allow for greater convenience for *** may also be implications for toxicity as well as disease *** this review we present a number of prospective and retrospective trials of SBRT in the treatment of prostate *** focus on factors such as biochemical progression-free survival,prostate specific antigen (PSA) response,and toxicity in order to compare SBRT to established treatment *** also discuss future steps that the clinical community can take to further explore this new treatment *** conclude that initial studies examining the use of SBRT in the treatment of prostate cancer have demonstrated impressive rates of biochemical recurrencefree survival and PSA response,while maintaining a relatively favorable acute toxicity profile,though long-term follow-up is needed.

Resolution of 2nd, 3rd or 4th interdigital space incomplete, simple syndactyly using a random vascularity flap

引用

Plastic and Aesthetic Research 2017年第4期4卷 70-75页

作者： Heriberto Garza de la Llave yusef Jiménez Murat Alejandroángel Corona Figueroa Hand Surgery Clinic Plastic and Reconstructive Surgery DepartmentHospital General Dr.Manuel Gea GonzálezMexico City 14080Mexico Facultad Mexicana de Medicina Universidad La SalleMexico City 14000Mexico.

Syndactyly consists of a variable fusion of soft tissue or of bone in adjacent fingers. This has important aesthetic and functional impacts on the development of the child due to the abnormal appearance of the hand. When the 1st web space is affected, it compromises grasp and development of the clamp function. Affliction of the 2nd, 3rd or 4th webspaces hinder the independent movement of the fingers adjacent to it. Current syndactyly release techniques have inherent disadvantages such as the use of skin from both the interdigital halves of the syndactylized fingers, the need to skin graft the donor site, postoperative flexion contracture, and need of 2 or more surgical procedures to obtain the desired result. The authors present 7 cases with incomplete simple 2nd, 3rd or 4th webspace syndactylies of multiple etiologies. All cases were treated at the unit of the corresponding author. The flap used in the treatment for all 7 cases did not require skin grafting of the flap donor site and used only skin from one of the fingers, while achieving a webspace dimension similar to normality, with a short recovery period. Furthermore, there were no postoperative finger contractures, diminishing the risk of future relapse.

Relationship between Radiological Lung Findings and Laboratory Ferritin and D-Dimer Levels in Patients with COVID-19 Infection

引用

International Journal of Clinical Medicine 2022年第10期13卷 468-477页

作者： Mona F. Kardus Rana A. Hallak Ahmed Alakedi Noha yusef Sindi Hadeel Abdullah Alhawas Shine Rashed Hessa Al-Twalah Ibrahim Khoja Department of Laboratory Medicine Dr. Sulaiman Al Habib Hospital—ARRYAN Riyadh Saudi Arabia Department of Laboratory Medicine King Saud Medical City Riyadh Saudi Arabia

Introduction: Pulmonary symptoms of COVID-19 infection range from asymptomatic infection to severe pneumonia. Pathogenesis and severity of symptoms were found to be related to the body’s immune response. Objectives: Ferritin and D-Dimer in COVID-19 confirmed cases can predict lung injury and possible poor patient prognosis. Materials and Methods: Patients who had been admitted to Dr. Sulaiman Alhabib-Arryan Hospital with positive COVID-19 polymerase chain reaction (PCR) tests between March 2020 and December 2021 were studied for blood ferritin and D-Dimer levels in relation to pulmonary radiological findings. Results: A total of 494 cases are included in this study. Male patients represent 74.1% of the cases, and the mean age is 51.68 ± 13.37 years. Increased age, ferritin, D-Dimer levels, and respiratory symptoms are factors that showed a statistically significant association with positive computed tomography (CT) findings. Receiver operator characteristic curve (ROC) showed that ferritin has a higher capability than D-Dimer to detect CT findings and that both are equal in predicting possible patient mortality. Suggested cutoff values for Ferritin > 336 ng/mL, with 78.21% sensitivity and 86.42% specificity and for D-Dimer > 0.55 mg/L FEU, with sensitivity of 74.82% and specificity of 75.31%. For mortality, the suggested cutoff point for ferritin is >864.6 ng/mL, which gives a sensitivity of 80.26 and a specificity of 64.83%. The suggested cutoff point for D-Dimer is >1.46 mg/L FEU, which gives a sensitivity of 65.79% and a specificity of 78.23%. Conclusion: Laboratory markers such as Ferritin and D-Dimer can be an accurate predictor of lung injury in COVID-19 patients and their increased values can predict the poor patient prognosis and possible mortality if aggressive hospital care is not provided.
