TÓM TẮT Mục tiêu: Mô tả đặc điểm lâm sàng, cận lâm sàng và tình hình điều trị bệnh nhân viêm khớp dạng thấp tại khoa Cơ xương khớp Bệnh viện Hữu nghị Đa khoa Nghệ An. Phương pháp: Phương pháp nghiên cứu mô tả cắt ngang được thực hiện trên 103 bệnh nhân viêm khớp dạng thấp tại khoa cơ xương khớp Bệnh viện hữu nghị đa khoa Nghệ An. Kết quả: Nữ giới chiếm 89,32% và 45,63% có độ tuổi từ 30 - 59 tuổi; Vị trí khớp khởi phát viêm hay gặp là khớp cổ bàn ngón tay (47,57%); 85,44%có thời gian cứng khớp buổi sáng ≥ 1h; 87,38%bệnh ở mức độ hoạt động mạnh; 91,26% có tốc độ máu lắng tăng và 97,07% có CRP dương tính; 54,37% có thiếu máu; 87,38 % có RF dương tính và 91,67% có anti-CCP dương tính cao; 53,40% số bệnh nhân có tổn thương gai đoạn 2 trên x-quang; 46,22% số bệnh nhân không tuân thủ điều trị thường xuyên tại thời điểm nghiên cứu và chỉ có 8,74% số bệnh nhân được điều trị bằng thuốc sinh học. Kết luận: Nghiên cứu đã cho thấy một số đặc điểm lâm sàng và cận lâm sàng của bệnh nhân viêm khớp dạng thấp điều trị tại khoa cơ xương khớp bệnh viện hữu nghị đa khoa Nghệ An. Có 87,38% số bệnh nhân bệnh có mức độ hoạt động mạnh theo thang điểm DAS. Có 46,22% số bệnh nhân không tuân thủ điều trị thường xuyên và chỉ có 8,74% số bệnh nhân được điều trị bằng thuốc sinh học. Từ khóa: Lâm sàng, cận lâm sàng, điều trị, viêm khớp dạng thấp ABSTRACT CLINICAL, SUBCLINICAL FEATURES AND TREATMENT SITUATION OF RHEUMATOID ARTHRITIS PATIENTS AT NGHE AN FRIENDSHIP GENERAL HOSPITAL Objective: To describe the clinical, subclinical features and treatment situation of patientswith rheumatoid arthritis at the rheumatology Department of Nghe An friendshipgeneral Hospital. Methods: The cross-sectional, descriptive study was conducted on 103 patients with rheumatoid arthritis at the rheumatology Department of Nghe An friendshipgeneralHospital. Results: Females account for 89,32% and 45,63% of patients are aged from 30 to 59 years old; The most common joint site of inflammation onset is the wrist, hand and finger joints (47,57%); 85,44% of patients have morning joint stiffness that was greater than 1h; 87,38% of the patients had a strong level of disease activity; 91,26% of patients had an increased erythrocyte sedimentation rate and 97,07% of patients had a positive CRP; 54.37% of patients have anemia; 87,38% of patients have positive RF test and 91.67% have high positive anti-CCP test; 53.40% of patients have stage 2 lesions on x-ray; 46,22% of patients did not adhere to regular treatment and only 8,74% of patients were treated with biologic drugs. Conclusion: The study showed some clinical and subclinical characteristics of patients with rheumatoid arthritis at the rheumatology Department of Nghe An friendshipgeneral Hospital. There are 87,38% of patients who had the strong level of disease activity according to DAS scale. There were 46,22% of patients who did not adhere to regular treatment and only 8,74% of patients were treated with biological drugs. Keywords: Clinical, subclinical, treatment, rheumatoid arthritis

Conventionally, Cu is preferred over Al to fabricate integrated inductors with higher quality factors on either silicon or sapphire substrates, profiting from its lower resistivity. However, after investigating and comparing these two kinds of metal multilayers in terms of fabrication process, electrical conductivity, in-depth profile analysis and performance of actual inductors, the Al-based metal multilayer exhibits competitive ability in fabricating thin-film inductors on sapphire compared to Cu-based multilayers. This is attributed to the degradation in electrical conductivity out of oxidation of Cu-based metal sublayers or forming alloys between them. Furthermore, in order to avoid complicated de-embedding procedures in the characterization of the on-chip inductors, a six-element equivalent physical model, which takes the parasitic effect of radio-frequency (RF) test structures into account, is proposed and validated by matching well with embedded measurement results.

Introduction: To determine the effects of non-treated seronegative rheumatoid arthritis (RA) on proximal renal tubule, sensitivity of Alanine aminopeptidase (AAP), g-glutamyltransferase (g--GT), β2 microglobulin in urine β2M), as well as relation with rheumatoid factor (RF) and C-Reactive protein (CRP), DAS 28 disease activity index. Methods: RF was determined by agglutination test (Latex RF test, while kinetic methods were used for determination of Alanine aminopeptidase (AAP) and g-glutamyltransferase (g-GT), as well as MEIA (Micro particle Enzyme Immunoassay) to determine β2 microglobulin in urine. Samples (serum and urine) of 70 participants were examined (35 RA not treated, 35 health control group). Results: In 35 RF negative RA, AAP enzymuria was present in 12 (34.28%) patients, g-GT was present in 7 patients (20%), while β2 microglobulin was present in 3 patients (8.57%). In the healthy control group, 4 patients showed AAP positivity (11.42%), 2 patients g-GT positivity (5.71%) and 1 patient showed presence of β2 microglobulin in urine (2.85). RF was not present in any patient (0%). Conclusion: AAP has a higher sensitivity of g-GT and b2 microglobulin in the detection of asymptomatic renal lesions in non treated seronegative RA.
