Objective To explore the clinical and pathological features of primary IgA nephrology in patients of different gender.Methods The clinical manifestations,laboratory examination and renal pathology results were compared in 192 IgA nephrology patients.Results Not only the onset age of the male patients was older than that of the female ones (P<0 .05 ),but also the course of disease before the kidney biopsy of male patients was longer than that of the female ones (P<0.05).Besides,the proportion of edema in the male patients was lower (P<0.05).The mean arterial pressure,hemoglobin and 24 h urine protein levels were higher in the male patients at the time of kidney biopsy.Besides,the proportions of high blood pressure,hyperuricemia and hypertriglyceridemia were all higher in the male patients.Furthermore,eGFR of the male patients was lower than that of the female ones (P<0 .05 ).There was a significant difference in the gender distribution of clinical and pathological types (χ2=12.666,P<0.05),and the male and female patients also significantly differed in the 24 h urine protein and CKD grouping (Z=-3.118,Z=-3.246,P<0.05).However,there was no significant sex difference in Lee pathology grading or immunofluorescence type (Z=-1.881,χ2 =-0.187,P>0.05 ).Patients of different gender significantly differed in the renal-interstitial lesions grading (Z=-3.0432,P<0.05);to be more specific,the scores of glomerulosclerosis and renal tubule interstitia were higher in the male patients (P<0.05).Conclusion Patients of different gender differ in the clinical and pathological features of primary IgA nephrology.And clinical pathology of male patients is worse than that of female ones.

Wound infections, secondary to acute and chronic wounds caused by mechanical, thermal, chemical factors, etc, not only delay wound healing but also may lead to mortality. The prolonged or inappropriate use of antibiotics lead to the growth of drug-resistant bacteria, resulting in refractory wound infections and poor treatment outcomes, which highlights the urgent need for effective therapies. Bacteriophages show great promise in treating drug-resistant wound infections due to their effectiveness in killing drug-resistant bacteria, their good resistance against bacterial biofilm (BBF) and their absence of cytotoxicity to eukaryotic cells. However, the mechanisms underlying bacteriophages′ resistance against BBF remain incompletely understood and their antibacterial efficacy for wound infections may also vary. For this purpose, the authors reviewed the biological characteristics and mechanisms of bacteriophages and their application in antibacterial therapies for wound infections, aiming to provide a reference for further research and application of bacteriophages in the treatment of wound infections.
