We report a case of NF2 presenting with a pathogenic somatic mutation in the NF2 gene in a woman harboring a germline splicing mutation in the NF1 gene. This case emphasizes the importance of sequence analy¬sis by using tumor tissues and the need to elucidate the role of a NF1 splicing mutation.

We experienced a patient with multiple myeloma whose urine contained a considerable amount of Bence Jones protein (BJP), which demonstrated poor thermal reactivity in heat coagulation test. The mechanism for this phenomenon was assessed.

Immunoelectrophoretic analyses reveal that a band corresponding to BJP in the urine had 2,600 Dalton by reduction after glycosidase treatment, but not after sialidase treatment. 2-Aminoethanethiol mouse In addition, the glycosidase-treated urine tested positive in heat coagulation test.

Glycosylation of the immunoglobulin light chain, which has rarely been seen, is the cause of the unexpected behavior of this patent's BJP in heat coagulation tests.

Chest CT is widely used in clinical diagnosis and efficacy evaluation of CAP. While repeated chest CT examinations to evaluate dynamic changes in chest CT images in a short period of time is a common phenomenon, it causes a lot of waste of medical resources, and due to the large dose of CT radiation, it can cause some harm to the human body. The purpose of this study is to establish a new model to predict the dynamic chest CT image changes of CAP patients by analyzing the age, smoking history, and serum inflammatory markers.

This is a retrospective study. All patients had received chest CT scan and serum inflammatory indexes were measured, including procalcitonin (PCT), high-sensitivity C-reactive protein (hs-CRP), white blood cell (WBC) and erythrocyte sedimentation rate (ESR). The second chest CT examination was performed after a week of treatment. General information on the medical record was also recorded (including age, smoking history, drinking history, and others). Main outcome measures were the chnsitivity in predicting dynamic CT changes in adult CAP patients.

To determine the diagnostic value of preoperative inflammatory biomarkers and CA199, alone or in combination, in diagnosing pancreatic cancer (PCC).

This retrospective study was comprised of 75 PCC patients and 83 healthy controls (HC). The participant's medical data was mined from the electronic records of the First Affiliated Hospital of Guangxi Medical University. The data included the preoperative circulating albumin/fibrinogen ratio (AFR), the platelet/lymphocyte ratio (PLR), the lymphocyte/monocyte ratio (LMR), the neutrophil/lymphocyte ratio (NLR), and the derived NLR (dNLR). The receiver operating characteristic (ROC) curve and the area under the ROC curve (AUROC) were used to evaluate the diagnostic efficacy of these candidate biomarkers for PCC.

A single AFR significantly distinguished PCC from the healthy controls (AUROC 0.903, 95% CI 0.846 - 0.945) and had a significantly higher sensitivity and larger AUROC than CA199 (AUROC 0.814, 95% CI 0.774 - 0.871). The combinations of AFR with CA199 (AUROC 0.932, 95% CI 0.881 - 0.966), RDW with CA199 (AUROC 0.905, 95% CI 0.849 - 0.946), Alb with CA199 (AUROC 0.869, 95% CI 0.806 - 0.917), and Fib with CA199 (AUROC 0.921, 95% CI 0.868 - 0.958) also yielded higher sensitivities and larger AUROCs than CA199 alone.

Circulating AFR was an effective biomarker in diagnosing PCC. Combining AFR, RDW, Alb, and Fib with CA199 could improve the diagnostic efficacy for PCC.

To establish the reference intervals of GIR, HOMA, and QUICKI index and to identify the clinical value of the three indexes for newly diagnosed diabetes mellitus.

The results of fasting glucose and insulin were acquired for 123 healthy individuals using Roche cobas-8000 to establish reference intervals of GIR, HOMA, and QUICKI based on Clinical and Laboratory Standards Institute (CLSI) EP28-A3. Meanwhile, 36 newly diagnosed type 1 and type 2 diabetes mellitus (DM) patients were enrolled to judge the effect of insulin resistance/insufficiency using the three indexes based on clinical initial treat-ment procedures. All the data were acquired from Wangjing Hospital, China Academy of Traditional Chinese Medicine.

The reference intervals of GIR, HOMA, and QUICKI were 5.83 - 21.15, 0.87 - 4.22, and 0.309 - 0.392, respectively. Concerning to GIR, HOMA, and QUICKI, there were 57.7% (15/26), 80.8% (21/26), and 80.8% (21/26) outside of the reference limit among type 2 DM patients, respectively; The area under the curve (AUC) of the GIR > 10.937, HOMA < 5.436, and QUICKI > 0.299 were 0.937 (95% CI 0.681 - 1.000), 0.689 (95% CI 0.510 - 0.868), and 0.689 (95% CI 0.510 - 0.868) by ROC curves when insulin insufficiency was judged based on whether insulin was included in initial treatment procedures. There concordance rates were 77.8% (28/36), 50% (18/36), and 50% (18/36) using the three indexes, GIR, HOMA, and QUICKI, respectively.

We established reference intervals for GIR, HOMA, and QUICKI. HOMA and QUICKI were more reliable indexes to identify insulin resistance among type 2 DM patients, but GIR was a more reliable index to identify insulin relatively or absolutely insufficiency than HOMA and QUICKI among DM patients.

In December 2019, a novel coronavirus (SARS-CoV-2) causing symptomatic illness (COVID-19) occurred in Wuhan, China. Travel-associated cases were reported in many other countries leading to epidemic transmission. The number of cases has increased rapidly but laboratory diagnosis is limited.

We collected samples from two groups of patients diagnosed with COVID-19 for experiments. In one group, 63 serum samples were analyzed IgG and IgM antibodies by enzyme-linked immunosorbent assay (ELISA) and 35 healthy serum samples were served as controls. In the other group, 91 plasma samples were analyzed by colloidal gold-immunochromatographic assay (GICA) for IgG and IgM antibodies and 35 healthy plasma samples were served as controls. Throat swab samples for nucleic acids retest were collected from 81/91 of these participant.

The sensitivity of the combined ELISA IgM and IgG detection was 55/63 (87.3%). Sensitivity of the com-bined GICA IgM and IgG detection was 75/91 (82.4%). Both methods were negative for healthy controls and had a specificity of 100%.
