Objective To investigate the effects of Sox30 gene mutations on spermatogenesis and sperm functionality.Methods CRISPR-Cas9 technology was used for gene editing to generate Sox30P636S mutant mice,and their genotypes were confirmed by Sanger sequencing.Sperm count,computer-assisted sperm analysis,hematoxylin-eosin(H&E)staining,and immunofluorescence were em-ployed to investigate the effects of Sox30 mutation on spermatogenesis and sperm viability in the mice.Results Compared to wild-type Sox30+/+mice,heterozygous Sox30P636S/+and homozygous Sox30P636S/P636S mice did not show statistically significant differences in testicu-lar size,weight,or mature sperm count(P＞0.5).Sperm motility analysis revealed that the proportion of motile sperm in homozygous Sox30P636S/P636S mice was approximately 10％ lower than that in wild-type Sox30+/+mice(P＜0.05),but no obvious abnormalities were observed in sperm formation process of the homozygous mice.Conclusion Although the Sox30P636S point mutation did not significantly impact the spermatogenesis process in mice,it moderately impaired their sperm motility to some extent.

Objective: To investigate and summarize the effect of narrative nursing on anxiety and depression in patients undergoing coronary artery bypass grafting, and to provide reference for the formulation of clinical nursing plan. Methods: A total of 61 patients underwent coronary artery bypass grafting were selected. 31 cases of narrative nursing were taken as the research group, and routine nursing was used in the other 30 cases as control group. Depression and anxiety were assessed by Self-rating Depression Scale (SDS) and Self-rating Anxiety Scale (SAS) before, 7 days after and 14 days after surgery. Results: Totally 61 patients were successfully operated and no case died during hospitalization. There was no significant difference in SAS and SDS scores between the 2 groups before surgery. The SAS scores in the study group were 57.9±4.2, 50.8±4.9, 47.1±5.0 on the day of admission,7 days after operation and 14 days after operation, respectively, while those in the control group were 58.4±3.7, 57.9±5.2, 55.7±6.2. There were significant differences between the two groups after intervention (t=5.490, 5.973, P<0.01). The SAS score of the study group decreased 7 days after operation and 14 days after operation compared with that of the admission day (t= 6.125, 9.209, P < 0.01). The SDS scores in the study group were 54.3±4.6, 49.4±4.7, 42.7±4.8 on the day of admission,7days after operation and 14 days after operation, respectively, while those in the control group were 54.1±5.1, 52.3±5.6, 51.6±5.2. There were significant differences between the two groups after intervention (t=2.194, 6.949, P<0.01). SDS scores in the study group decreased 7 days after operation and 14 days after operation compared with the day of admission in this group, with significant differences (t=4.148, 9.715, P < 0.01). Conclusions Narrative nursing is helpful to relieve anxiety and depression in patients undergoing coronary artery bypass grafting.

Objective To investigate the timing of early naso-jejunum nutritional support on severe acute pancreatitis(SAP) patients and its feasibility and safety. Methods 72 patients with SAP were enrolled and randomized into experiment group and control group according to random number. EN (enteral nutrition) was administrated in the experiment group when the patients' circulation were relatively stable, abdominal distention decreased and the bowel sound could be heard; while EN was administrated in the control group when the patients' vital signs were stable, and peristalsis recovered with exhaust and sense of hunger, without obvious abdominal distention. The cultivation of secretions, hospital stay and overall cost of hospitalization were evaluated in the two groups of patients. Results The throat swabs, sputum culture, mid-portion urine culture of the two group were not significantly different. But the fecal culture in the experiment group was significantly lower than those of the control group (5.6% vs. 33.3%, P ＜ 0. 01); the hospital stay and overall cost of hospitalization in the experiment group was (26.0 ± 15.2)d and (78910 ± 77734)Yuan, which were significantly lower than those in the control group [(32.9 ± 22.3) d and (149528 ± 145936) Yuan, P ＜0.05]. Conclusions Appropriately bringing forward EN is safe and feasible, which can shorten clinical course and reduce the cost of hospitalization.
