The indicators required to determine the ANI include AST, ALT, MCV, gender, height, and weight. Clinical parameters of height, weight, waist circumference, and blood pressure were recorded on the admission day, while serum samples were collected during the following morning after fasting for 12 hours. The biochemical indicators, including AST, ALT, MCV, GGT, total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), and fasting blood glucose (FBG), were detected by the Hitachi 7180 automatic biochemical analyzer (Hitachi, Tokyo, Japan) and supporting reagents. The ANI value was calculated with an online calculator provided by the Mayo Clinic (Rochester, MN, USA, official website: http://www.mayoclinic.org/gi-rst/mayomodel10.html).

Urinary total protein (Pyrogallol red-molybdate method) was measured by 7180 automatic biochemical analyzer (Hitachi). For proteinuria, there was 1 missing value in patient with negative serum anti-PLA2R antibody and positive glomerular PLA2R deposition. Serum total protein (Biuret method), serum albumin (Bromcresol green method), serum creatinine (Jaffe method), and serum urea (Urease methods) were measured by Synchron DXC800 automatic biochemical analyzer (Beckman Coulter). Estimated glomerular filtration rate (eGFR) levels were calculated using the Chronic Kidney Disease Epidemiology Collaboration equation recommended by the Kidney Disease Improving Global Outcomes.[9 (link)]

Comprehensive Metabolic Profiling of Fasting Patients

Check if the same lab product or an alternative is used in the 5 most similar protocols
The venous blood was collected from the peripheral forearm of the enrolled patients after an overnight fast of 8–12 hours. TC, TG, HDL, LDL, liver, kidney function tests, and other biochemical indices were measured using the Hitachi 7180 automatic biochemical analyzer. HBA1c was determined by high-pressure liquid chromatography. An OGTT, insulin release test, and glucagon release test were performed. Patients were inhibited from using insulin secretagogue three day before the blood draw. 75 g glucose was administered orally after an overnight fast of 12 hours. Venous blood from the forearm was collected at 0, 30, 60, 120, and 180 mins, respectively, to evaluate the FBG and 2hPBG, insulin and glucagon levels. The glucose oxidase method was used to assess glucose levels. Insulin was measured by electrochemical luminescence (Roche, Germany), and glucagon was measured by nonequilibrium radioimmunity.

Serum was collected after the mice were sacrificed and was centrifugated at 3000 × g for 10 min. Then, the serum was subjected to liver and kidney function analysis using the Hitachi 7180 automatic biochemical analyzer (Tokyo, Japan). The rate method was used to measure aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH); the hexokinase method was used to measure glucose (GLU); the enzymatic method was used to measure creatinine (Cr) and UREA; the uricase ultraviolet method was used to measure uric acid (UA); the bromocresol green method was used to measure albumin (ALB); the biuret method was used to measure total protein (TP) and globulin (GLOB).

Among the 14 routine methods, three were from foreign companies (Roche, Diasys, and Wako), and the others were from Chinese companies (Sichuan Maccura, Beijing Strong, DIRUI, Leadman, Mindray, Shanghai Fosun Long March, Kehua, Reebio, Biosino, Long March I (OCPC), and Long March II [the azo arsenic III method]). All tests were completed on a Hitachi 7180 automatic biochemical analyzer and the parameters were set in accordance with the manufacturer's instructions. Calibration was performed with supporting calibrators before the measurements. All of the samples were detected twice, and their order of measurement was reversed in the replicate run.

Biochemical Analysis of Hepatitis B

Check if the same lab product or an alternative is used in the 5 most similar protocols
A Hitachi 7180 automatic biochemical analyzer (Japan) performed routine biochemical tests during therapy at the follow-up point. Serum HBsAg levels, antibody to HBsAg (HBsAb), HBeAg, and antibody to HBeAg (HBeAb) were determined by an Architect I2000SR electrochemistry luminescence immunity analyzer (U.S.A). HBsAg and HBsAb levels were expressed in IU/mL and mIU/mL and had dynamic detection ranges which are 0–124,950 IU/mL and 0–1000 mIU/mL, respectively. HBeAg and HBeAb were determined semi-quantitatively and expressed as the signal-to-cut-off ratio (S/CO). Liver stiffness measurement (LSM) was assessed by FibroScan-502 (Echosens, Paris, France), equipped with an M-type probe at 3.5 MHz. The result for LSM was presented in kPa.

After four rounds of OPGMN weekly medication in 5-week-old C57BL/6 mice, serum and liver were harvested to assess liver function and toxicity. The collected serum was analyzed for a liver function index, including albumin, total protein, total bilirubin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP), using a Hitachi 7180 automatic biochemical analyzer. Liver toxicity was analyzed using hematoxylin and eosin (H&E) staining.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
