Evaluation of Disease Activity of Systemic Lupus Erythematosus by D-dimer Combined with Red Blood Cell Distribution Width.

Background: To investigate the value of D-dimer combined with red blood cell distribution width (RDW) in evaluating the disease activity of systemic lupus erythematosus (SLE).

Methods: A total of 105 SLE patients confirmed in our hospital from July 2018 to September 2020 were collected as the SLE group, and 60 healthy persons matched in age and gender during the same period were collected as the control group. According to the SLEDAI score, SLE patients were divided into SLE active group and SLE inactive group, and RDW and D-Dimer levels were detected.

Diagnostic value of urinary microprotein concentration for patients with negative urinary protein test results and positive urinary casts on microscopic examination.

Objective: To analyze the association between positive urinary casts on microscopic examination and urinary microprotein concentration in the case of negative urinary protein test results. This study also investigated the diagnostic value of urinary microprotein examination.

Subjects: A total of 949 samples that were analyzed with a UF-1000i Urine Analyzer and returned cast alarm results were categorized into two groups, a positive and negative group, according to qualitative urinary protein sulfosalicylic acid test results.

[Influence of human activities on groundwater environment based on coefficient variation method].

Groundwater system in the plain area of Beijing can be divided into six subsystems. Due to the different hydrogeological conditions of the subsystems, the degrees to which human activities affect the subsystems are also diverse. In order to evaluate the influence of human activities on each subsystem, the first and second aquifer with relatively poor water quality were chosen to be the evaluating positions, based on the data of groundwater sampled in September, 2011.

N'-(3-Hy-droxy-benzyl-idene)-4-methyl-benzohydrazide.

The title compound, C(15)H(14)N(2)O(2), was obtained from the reaction of 3-hy-droxy-benzaldhyde and 4-methyl-benzo-hydrazide in methanol. In the mol-ecule, the benzene rings form a dihedral angle of 2.9 (3)°.
