Background： Nontraumatic osteonecrosis of the femoral head （NONFH） is a debilitating disease that represents a significant financial burden for both individuals and healthcare systems. Despite its significance, however, its prevalence in the Chinese general population remains unknown. This study aimed to investigate the prevalence of NONFH and its associated risk factors in the Chinese population. Methods： A nationally representative survey of 30,030 respondents was undertaken from June 2012 to August 2013. All participants underwent a questionnaire investigation, physical examination of hip, and bilateral hip joint X-ray and/or magnetic resonance imaging exalnination. Blood samples were taken after overnight fasting to test serum total cholesterol, triglyceride, and high-density lipoprotein （HDL） and low-density lipoprotein （LDL） levels. We then used multivariate logistic regression analysis to investigate the associations between various metabolic, demographic, and lifestyle-related variables and NONFH. Results： NONFH was diagnosed in 218 subjects （0.725%） and the estimated NONFH cases were 8.12 million among Chinesepeople aged 15 years and over. The prevalence of NONFH was significantly higher in males than in females （1.02% vs. 0.51%, x^2 = 24.997, P 〈 0.001 ）. Among NONFH patients, North residents were subjected to higher prevalence of NONFH than that of South residents （0.85% vs. 0.61%,x^2= 5.847, P = 0.016）. Our multivariate regression analysis showed that high blood levels oftriglycerides, total cholesterol, LDL-cholesterol, and non-H DL-cholesterol, male, urban residence, family history of osteonecrosis of the femoral head. heavy smoking, alcohol abuse and glucocorticoid intake, overweight, and obesity were all significantly associated with an increased risk of NONFH. Conclusions： Our findings highlight that NONFH is a significantpublic health challenge in China and underscore the need for policy measures on the national level. Furthermore, NONFH shares a n

基于对影响非线超声性检测因素的探讨,考察了应用非线性检测无损评价HR3C烟侧腐蚀的可行性。结果表明:脉冲激励串个数n≤2df/c,加汉宁窗有助于降低系统干扰,此外,样品表面粗糙度对非线性系数β产生显著的影响。随腐蚀时间的延长,非线性系数呈现阶段性的递增趋势。腐蚀初期(腐蚀时间在50h以内),非线性系数增幅不足20%;然而,腐蚀至150h,非线性系数显著增加;相对于未腐蚀样品,腐蚀200h时的非线性系数增幅达260%。非线性系数的单调变化与腐蚀损伤的加剧相一致,因此,应用超声非线性无损评价HR3C的烟侧腐蚀是可行的。

The investigation of the painting materials (pigments, binders and varnish) of Agarbiciu wooden church painted walls was done by employing both nondestructive (XRF and reflection FTIR spectroscopy for pigments) and destructive methods (FTIR spectroscopy and GC-MS spectrometry for pigments and binders). The digital restoration of the interior of the wooden church was done using the physical-chemical composition of the painting layer, a metadata set that describes the timeline, detailed photographic documentation and the 3D scanned interior of the church.

Background: Acute kidney injury (AKI) is a common in community and a serious outcome in hospital setting. Despite the progress of dialytic and non-dialytic therapeutic means, its mortality remains high. Our objective was to contribute to a better knowledge of how AKI managed in an emergency medical ward in an African country located in the southern part of the Sahara. Patients and Methods: We conducted a retrospective study from January 1 to December 31, 2019, conducted at the emergency department of the University Teaching Hospital of Bouake, on cases of AKI. Results: During the study period, we collected 221 cases of AKI out of a total of 1778 files giving a prevalence of 12.4%. The mean age was 54 ± 19 years. A male predominance with a sex ratio of 1.4 was observed. The main past histories were hypertension in 40.4%, cardiac disease in 16.9%, and diabetes in 14.3%. The patients in were classified in 63.8% of cases as stage I, in 22.1% as stage II and in 14.1% as stage III according to the AKIN criteria. AKI was functional in 93.2% of cases. Hemodialysis was indicated in 15 (6.8%) patients, but only 3 (1.4%) underwent it. The mortality rate was 45.2%. Factors associated with mortality were: creatinine level greater than or equal to 30 mg/l, sepsis and impaired vigilance. Conclusion: Acute renal failure was frequent in subjects under 60 years old. Its mechanism of occurrence is functional and therefore it can be prevented by vascular filling. The majority of patients were seen at AKIN Stage I. The outcome was favorable in more than one third of the cases and the mortality rate remains high.

Background: Viral hepatitis C is a major public health problem in the world. The advent of direct-acting antivirals has revolutionized the taking in charge and prognosis of patients infected with the hepatitis C virus. The interest of this presentation is to draw attention to the problem of therapeutic care posed by viral hepatitis C in kidney transplant patients in C?te d’Ivoire, a country with limited resources where all direct-acting antivirals are not yet available. Patient observation: We report the case of a kidney transplant of 52 years old, chronic bearer of viral hepatitis C virus who after his kidney transplant presented, decompensated active cirrhosis. A treatment based on Sofosbuvir 400 mg/Ledipasvir 90 mg in this patient with genotype 2 for 12 weeks was initiated. A sustained virological response was observed 12 weeks after the end of treatment. Conclusion: Direct-acting antivirals offer the possibility of antiviral C treatment without interferon or ribavirin in cirrhotic renal transplant.

阿多诺关注音乐在意识及社会生活的心理文化中所扮演的角色,揭示音乐具有社会教育功能。蒂亚·德诺拉在此基础上进而思考音乐如何源于行为,以及音乐如何参与音乐事件的问题,这些问题使人们开始广泛关注不同类型的音乐材料如何在不同的时间为不同的演员提供不同的事物,以创造各种可能性的音乐事件。这使音乐学和社会学超越了两者学科之间的传统界限,转而更为紧密地结合在一起,从社会学的角度关注音乐文化,从而形成一种新型的跨学科的研究课题。

以‘凯特’杧果为材料,研究了栽培中果实套袋至采果时、采前除袋和除袋后喷钙3种处理对采后果皮着色、果实品质和耐贮性的影响。结果表明:3种处理的果实采后果皮的花青苷和类黄酮含量显著降低,总酚含量在青熟时显著低于对照,但完熟后显著高于对照;3种处理不仅加速果皮由绿色向黄色转变,显著提高果皮和果肉的钙含量,而且显著降低果实采后软化速率并抑制果实病情发展,其中除袋后喷钙处理效果最佳;3种处理果实在青熟时果肉淀粉含量显著高于对照,而蔗糖和维生素C含量显著低于对照,但完熟后果实蔗糖、还原性糖、可滴定酸和维生素C含量与对照没有显著差异。3种处理均有利于改善果实的外观品质,并提高果实的耐贮性。
