β2-adrenergic receptor (β2-AR) agonists are widely used as first-line drugs in the treatment of bronchial asthma (hereinafter referred to as “asthma”), but long-term use can lead to β2-AR desensitization and reduce its clinical efficacy, resulting in poor symptom control of some asthma patients. The mechanism of β2-AR desensitization induced by β2-AR agonists mainly includes slow hyposensitization (related to the decrease of β2-AR density in airway mucosa) and rapid hyposensitization (related to the mechanism of stimulatory G protein decoupling). Cyclic adenosine monophosphate(cAMP)-protein kinase A and cAMP- exchange protein activated by cAMP signaling pathways are closely related to β2-AR desensitization. Glucocorticoids, peroxisome proliferator-activated receptor-gamma agonists, ASM-024, Chinese medicine monotherapies and formulations, when combined with β2-AR agonists, can improve the sensitivity of β2-AR, so as to better control asthma symptoms.

Objective:
To examine the causal relationship between body mass index (BMI) and 25 types of autoimmune diseases (ADs) using Mendelian randomization (MR) study method.
Methods:
The genome-wide association study (GWAS) data for BMI and 25 types of ADs were obtained from IEU OPEN GWAS database. Single nucleotide polymorphisms (SNPs) related to BMI were used as instrumental variables, 25 types of ADs were used as study outcomes, and MR analysis was performed using inverse variance weighted (IVW) method. Heterogeneity was evaluated using Cochran's Q test, horizontal pleiotropy was tested using MR-Egger regression and MR-PRESSO, and results robustness was verified with leave-one-out method.
Results:
Cochran's Q test showed heterogeneity of MR analysis results (P<0.05), and a random effect model was employed. The results of MR analysis showed that elevated BMI increased the incidence risks of type 1 diabetes mellitus (OR=1.519, 95%CI: 1.281-1.801), IgA nephropathy (OR=1.227, 95%CI: 1.134-1.327), adult Still disease (OR=1.002, 95%CI: 1.001-1.003), multiple sclerosis (OR=1.303, 95%CI: 1.115-1.523), narcolepsy (OR=1.029, 95%CI: 1.017-1.040), Hashimoto thyroiditis (OR=1.561, 95%CI: 1.391-1.751), autoimmune hepatitis (OR=1.481, 95%CI: 1.076-2.038), rheumatoid arthritis (OR=1.209, 95%CI: 1.054-1.386), psoriasis vulgaris (OR=1.719, 95%CI: 1.427-2.070) and pernicious anemia (OR=1.001, 95%CI: 1.000-1.002). No causal relationship was found with other ADs (all P>0.05). MR-Egger regression identified no horizontal pleiotropy of instrumental variables (all P>0.05), while MR-PRESSO test identified partial horizontal pleiotropy (all P<0.05), which remained consistent with the original results after adjustment (P>0.05). Leave-one-out analysis showed results robustness.
Conclusion
There are causal relationship among BMI and type 1 diabetes mellitus, IgA nephropathy, adult Still disease, multiple sclerosis, narcolepsy, Hashimoto thyroiditis, autoimmune hepatitis, rheumatoid arthritis, psoriasis vulgaris and pernicious anemia.

Rituximab is currently used as a first-line therapy for phospholipase A 2 receptor-associated membranous nephropathy due to its good efficacy and safety. Although the remission rate after rituximab treatment is more than 60%, nearly 40% patients still do not respond to treatment. We used obinutuzumab to treat 3 cases of rituximab resistant PLA 2R-associated membranous nephropathy. After the first dose of 1 000 mg with or without additional dose, the amount of anti-PLA 2R antibody and urinary protein decreased significantly and the adverse reactions were mild. The results show that obinutuzumab has a certain therapeutic effect on rituximab resistant PLA 2R-associated membranous nephropathy, but the time of follow-up observation is short and can only be used as individual cases, which needs to be confirmed by a large sample and high-quality prospective cohort study.

The paper reports a rare case of alkaptonuria (AKU) with IgA nephropathy, and analyzes its clinical manifestations, imaging findings, pathological features, gene diagnosis and treatment process, so as to provide reference for the diagnosis and treatment of the disease. The clinical symptoms of the patient were mainly black urine, microscopic hematuria and proteinuria. Renal pathology showed mild mesangial hyperplasia IgA nephropathy, and renal tubular epithelial cytochrome deposition. Genetic analysis indicated that a pathogenic mutation was detected on the AKU-related homogentisate 1, 2-dioxygenase gene possibly associated with the phenotype of the patient. Genetic testing and renal pathology were effective methods to make a definite diagnosis for the case.

Objective:To calculate the single-event dose-averaged specific energy of particles delivered in spherical domains based on the track structure model and using triple integration, and to investigate the influence of the domain shape on the key model parameters of microdosimetric kinetic model (MKM) and its corresponding physical significance.Methods:The domains are assumed to be cylinders and spheres, respectively. With α 0, domain radius, rd, and nucleus radius, Rn, as undetermined coefficients, the nuclear charge numbers, kinetic energies and their corresponding LETs of three kinds of charged particles ( 3He, 12C, 20Ne) as independent variables, D10 as dependent variable, the mean value of squared residuals, J2, between the D10 calculated values and D10 experimental values as the optimization objective, the final fitting values of the above undetermined coefficients of human salivary gland (HSG) cells and Chinese hamster lung (V79) cells obtained after iteration by the robust least square method are the optimal model parameter values of MKM. Results:For HSG cells, cylindrical domain: α 0=0.073/Gy, rd=0.29 μm, Rn=4.1 μm, J2=0.039 7 Gy 2; spherical domain: α 0=0.023/Gy, rd=0.29 μm, Rn=4.4 μm, J2=0.039 3 Gy 2; For V79 cells, cylindrical domain: α 0=0.114/Gy, rd=0.25 μm, Rn=3.8 μm, J2=0.097 4 Gy 2; spherical domain: α 0=0.095/Gy, rd=0.26 μm, Rn=4.1 μm, J2=0.096 9 Gy 2. Conclusions:For the same type of cells, cylindrical and spherical domains were selected respectively, and there are significant differences in MKM parameters obtained by fitting. The fitting values of the domain radius, rd of the two shapes of domains show no significant difference, while the fitting values of α0 of spherical domains are smaller than those of cylindrical domains, the fitting values of nucleus radius, Rn, of spherical domain are larger than those of cylindrical domains, closer to the nucleus radius observed by fluorescence microscopy. In the low LET (<20 keV/μm) region, D10 calculated according to the parameters of the two different shapes of domains are different, so the selection of the domain shape will cause differences in the relative biological effectiveness(RBE) calculation of proton in the region near Bragg peak.
