Background: Homozygosity at HLA-I locus has been reported to be an unfavorable predictive biomarker of second-line or beyond immunotherapy in patients with different types of cancer. The linkage between HLA-I zygosity and survival in NSCLC patients treated with first-line immunotherapy with or without chemotherapy has not been reported.
Methods: Next generation sequencing with HLA genotyping was performed on patients with advanced NSCLC treated with immune checkpoint inhibitors with or without chemotherapy as first-line (N = 29). Progression free survival was compared between HLA-I homozygous (defined as homozygosity in at least one locus A, B, or C) and heterozygous patients. Kaplan-Meier curves were built, and log-rank test was used.
Results: Among 29 enrollees, 25 patients (86.2%) were HLA-I heterozygous and four patients (13.8%) were HLA-I homozygous. Treatment response was not available in five patients with HLA-I heterozygosity. Among 20 patients with HLA-I heterozygosity, five patients (20.0%) had partial response, 10 patients (50.0%) had stable disease, two patients (8.0%) had non-complete response/non-progressive disease, and three patients (12.0%) had progressive disease. Among four patients with HLA-I heterozygosity, one patient (25.0%) had partial response, one patient (25.0%) had stable disease, and two patients (50.0%) had progressive disease. The median progression free survival was not reached in heterozygous group and was 2.97 months in homozygous group (Log-rank p = 0.68).
Conclusions: We observed a trend toward an inverse association between HLA-I homozygosity and survival outcomes in patients with NSCLC treated with first-line therapy in conjunction with immunotherapy. Further prospective studies to validate aforementioned relationship are warranted.

This was an original article, and the objective of this study was to investigate the effects of bipolar transurethral plasma kinetic prostatectomy (TUPKP) on urodynamics and sexual function in benign prostatic hyperplasia (BPH) patients. One hundred and four BPH patients were divided into a control group and an intervention group. The control group received transurethral resection of prostate, while the intervention group received TUKEP.

This study examined the effects of a combination of plan-do-check-action (PDCA) and enhanced recovery after surgery (ERAS) on patients undergoing cesarean section. One hundred and thirty patients undergoing caesarean section at the Second Affiliated Hospital of Nantong University comprised the study group. They were randomly divided into a control group (CG) and an intervention group (IG).

Giant ovarian cysts (GOCs) have become less common in developed countries due to routine health screenings, but they remain prevalent in economically underdeveloped regions. Treatment options for GOCs depend on factors such as age, cyst characteristics, and pregnancy status. Minimally invasive single-port laparoscopic surgery has largely replaced traditional open surgery due to its aesthetic advantages and effectiveness.

This study sought to compare bacterial abundance and diversity in milk and feces of healthy lactating women with patients suffering from lactation mastitis, explore the pathogenesis of lactation mastitis, and develop new ideas for its treatment and prevention from a microbiological perspective. A total of 19 lactating mastitis patients and 19 healthy lactating women were recruited. Milk and fecal Specimens were obtained from both groups, and microbial community structure was analyzed using 16S rRNA gene sequencing.

Background: Weighted blankets have recently introduced in the treatment on insomnia as a nonpharmacological integrative therapy. Here we prospectively evaluated the effects of weighted blankets on the sleep structure and heart rate variability (HRV) in patients with primary psychophysiological insomnia.
Methods: In this prospective polysomnographic (PSG) study between August 2021 and August 2022, patients were given weighted blankets (~10% of body weight) to use at home for 10 nights consecutively.
