Diabetic nephropathy (DN), as one of the most common complications of diabetes, is a primary cause of end-stage renal disease. The pathogenesis of DN encompasses processes such as chronic inflammation, recruitment and activation of immune cells, tubular and glomerular injury, and renal fibrosis. These processes are highly correlated with the activation of the nucleotide-binding oligomerization domain-like receptor pyrin domain containing 3 (NLRP3) inflammasome and the resulting pyroptosis it mediates. Previous studies have shown that the release of pro-inflammatory cytokines, leakage of damage-associated molecular patterns (DAMPs), recruitment and activation of immune cells can be reduced by regulating the NLRP3 inflammasome and its mediated pyroptosis, thereby slowing the diffusion of inflammatory responses in adjacentcells, fibrosis, and tissue remodeling processes. Ultimately, these process can improve renal injury and dysfunction caused by diabetic nephropathy. This article summarizes the molecular regulatory mechanisms of the NLRP3 inflammasome and its mediated pyroptosis at different pathological stages of DN, proposes potential targets for regulating their activation, aiming to provide a new direction for personalized treatment of DN.

Objective: To summarize the laboratory findings of a case of hemolytic disease of the fetus and newborn (HDFN) caused by Rh system anti-c antibodies and to review the literature, so as to explore the characteristics of anti-c HDFN. Methods: The ABO blood type, Rh blood type, direct antiglobulin test (DAT) results, and the presence of unexpected antibodies and their titers were determined by serological methods. The cases of anti-c HDFN in our laboratory in China and abroad were statistically analyzed, and the incidence of severe HDFN caused by anti-c, anti-D and anti-E was compared. Results: The blood type of the child was B (Rh CcDee) with a positive DAT. Anti-c antibody was detected in both serum and eluate, with a serum antibody titer of 4. The mother’s blood type was AB (Rh CCDee) with a negative DAT, and anti-c antibody was detected in the serum with a titer of 128. Among 20 cases of anti-c HDFN, 17 were DAT positive, and 9 (45%, 9/20) underwent blood transfusion or exchange transfusion. The incidence of severe HDFN was 47.60% (10/21) for anti-c, 47.60% (10/21) for anti-D and 31.30% (5/16) for anti-E. Conclusion: Maternal pregnancy and/or blood transfusion are the main reasons for the production of Rh alloantibodies such as anti-c. The prevention and management of anti-c should be similar to that of anti-D. Rh antigen-matched (five antigens of Rh blood group) transfusion is necessary for women of childbearing age to avoid antibody production, and Rh typing and antibody screening during prenatal examination is recommended to ensure early detection, intervention and treatment.

PURPOSE: Self-management is critical to improve health outcomes of elderly patients with coronary heart disease (CHD). Sense of coherence (SOC) is found to be linked with self-management behaviors. However, their deeper relationship is not clear. The purposes of this study were to investigate the association between SOC and self-management behaviors among elderly CHD patients in China, and whether confrontation mediates this association. METHODS: A cross-sectional design was used. A total of 275 elderly patients with CHD recruited from the cardiology department in a general hospital in North China were surveyed from October 2015 to April 2016. SOC, confrontation, and self-management behaviors were measured using the Chinese version of the SOC scale, subscale of Medical Coping Modes Questionnair—Confrontation, and the CHD self-management scale, respectively. Correlation analysis and path analysis were conducted to analyze the data. RESULTS: The mean (±standard deviation) scores of SOC, confrontation, and self-management behaviors were 62.20 (±9.61), 19.55 (±3.15), and 76.17 (±10.63), respectively. Correlation analysis showed that SOC, confrontation, and self-management behaviors were significantly correlated with each other. Path analysis indicated that SOC exerted a direct effect on self-management behaviors, whereas could affect self-management indirectly via confrontation. Bootstrap test result showed that confrontation played a mediating role (β = .20, p < .001) in the relationship between SOC and self-management behaviors. CONCLUSION: SOC was related to self-management behaviors, whereas confrontation mediated the effect of SOC on self-management behaviors. In practice, the role of confrontation coping should be valued when developing strategies to strengthen SOC and to improve self-management practice among elderly CHD patients.

OBJECTIVE This study was conducted to analyze the underlying bacterial pathogens of the tonsils and adenoids in children with sleep-disordered breathing(SDB).METHODS The core tissue from the tonsils and/or adenoids of 163 SDB children was cultured aerobically. Of the 163 cases, 120 children underwent adenoidectomy and tonsillectomy simultaneously(A+T), 39 children underwent adenoidectomy(A) and 4 tonsillectom(T) only. 124 children who underwent tonsillectomy were subdivided into two groups based on history(with or without a history of recurrent tonsillitis). 71 children with the history were enrolled in the 'recurrent tonsillitis group' and 53 children without the history were enrolled in 'non- recurrent tonsillitis group'.RESULTS Of the total 120 cases who underwent A+T, 114(95.00%) cases had same distribution of bacteria detected in both sides in the same patient. Besides this, 17 cases in whom mixed organisms were identified in both sites shared common pathogen. No significant difference in the detection rates of staphylococcus aureus and haemophilus influenzae were found when we compared seasons(Tonsil:χ2=8.538,P=0.201; Adenoid:χ2=5.427, P=0.490). No significant difference in the type and detection rate of essential bacteria was found when we compared between recurrent tonsillitis group and 'non-recurrent tonsillitis group' (χ2=3.028,P=0.387).CONCLUSION The bacterial isolates from the tonsils and adenoids are virtually identical in type and detection rate in the same SDB patient. The bacterial distribution of the tonsillar and adenoidal core is unaffected by the seasonal variation and history of recurrent tonsillitis.
