This paper primarily investigated the protective effects and potential mechanisms of total saponins from Ginseng Radix et Rhizoma and Notoginseng Radix et Rhizoma in alleviating isoprenaline(ISO)-induced hypertrophy and damage in H9c2 cardiomyocytes. Initially, H9c2 cardiomyocytes were used as the research subject to analyze the effects of ISO at different concentrations on cell hypertrophy and damage. On this basis, the H9c2 cardiomyocytes were divided into blank, model, and high-dose(200 μg·mL~(-1)), medium-dose(100 μg·mL~(-1)), and low-dose(50 μg·mL~(-1)) groups of total saponins from Ginseng Radix et Rhizoma and Notoginseng Radix et Rhizoma. Cell hypertrophy and damage models were induced by treating cells with 400 μmol·L~(-1) ISO for 24 hours. The Incucyte live-cell analysis system was utilized to observe the status, size changes, and confluence of the cells in each group. Cell viability was detected by using the CCK-8 assay. Western blot analysis was employed to detect the expression of Ras-associated protein 7A(RAB7A), sequestosome 1(SQSTM1/p62), autophagy-related protein Beclin1, and microtubule-associated protein 1 light chain 3(LC3). Immunofluorescence was used to detect the expression level of the autophagy marker Beclin1 in H9c2 cells. The results demonstrated that compared with the blank group, the model group showed a significant reduction in cell viability(P<0.01) and a marked increase in cell hypertrophy, with an average cell length growth of 13.53%. Compared with the model group, the high-dose, medium-dose, and low-dose groups of total saponins from Ginseng Radix et Rhizoma and Notoginseng Radix et Rhizoma exhibited reduced hypertrophy, with respective growths of 6.89%, 8.30%, and 8.49% and a significant decrease in growth rates(P<0.01). Cell viability in the high-dose of total saponins from Ginseng Radix et Rhizoma and Notoginseng Radix et Rhizoma was also significantly increased(P<0.01). Western blot and immunofluorescence results indicated that compared with the blank group, the model group showed changes in Beclin1, RAB7A, and p62 expression, as well as the LC3Ⅱ/LC3Ⅰ ratio, although most changes were not statistically significant. In the groups treated with total saponins from Ginseng Radix et Rhizoma and Notoginseng Radix et Rhizoma, the expression of autophagy-related proteins Beclin1 and RAB7A and the LC3Ⅱ/LC3Ⅰ ratio were significantly increased(P<0.05), while p62 expression significantly decreased(P<0.05). These findings collectively suggested that pretreatment of cells with total saponins from Ginseng Radix et Rhizoma and Notoginseng Radix et Rhizoma significantly enhanced autophagy activity in cells. In summary, total saponins from Ginseng Radix et Rhizoma and Notoginseng Radix et Rhizoma inhibit ISO-induced hypertrophy and damage in H9c2 cells by promoting autophagy, demonstrating potential cardioprotective effects and providing new insights and scientific evidence for their preventive and therapeutic use in cardiovascular diseases.

Nonobstructive azoospermia (NOA), one of the most severe types of male infertility, etiology often remains unclear in most cases. Therefore, this study aimed to detect four biallelic detrimental variants (0.5%) in the minichromosome maintenance domain containing 2 ( MCMDC2 ) genes in 768 NOA patients by whole-exome sequencing (WES). Hematoxylin and eosin (H&E) demonstrated that MCMDC2 deleterious variants caused meiotic arrest in three patients (c.1360G>T, c.1956G>T, and c.685C>T) and hypospermatogenesis in one patient (c.94G>T), as further confirmed through immunofluorescence (IF) staining. The single-cell RNA sequencing data indicated that MCMDC2 was substantially expressed during spermatogenesis. The variants were confirmed as deleterious and responsible for patient infertility through bioinformatics and in vitro experimental analyses. The results revealed four MCMDC2 variants related to NOA, which contributes to the current perception of the function of MCMDC2 in male fertility and presents new perspectives on the genetic etiology of NOA.

OBJECTIVE:
Serological and molecular biological analysis of a B(A) subtype family was carried out to explore the underlying mechanism of B(A) subtype and clinical safe blood transfusion strategies.
METHODS:
The ABO blood type of the proband and her four family members were identified by serological methods, and serological experiments such as anti-H, anti-A1 and absorption-elution tests was added. In addition, the exons 6 and 7 of the ABO gene were sequenced by PCR-SSP (polymerase chain reaction - sequence specific primer).
RESULTS:
The serological results showed that the agglutination intensity of the proband, her mother and her maternal grandmother was imbalanced during forward typing, showing weak A and strong B antigens, and there were strong H antigens and their intensity were higher than that of normal B type. The results of reverse typing indicated the presence of weak anti-A1 antibodies, and human anti-A was positive in the absorption-elution test. Genetic sequencing revealed a characteristic mutation of c.700 C>G in all three individuals. The sequencing results showed that the proband was B(A)02/B01, her mother was B(A)02/O02, and her maternal grandmother was B(A)02/O01 . According to the compatibility principle, 1.5 units of type O washed red blood cells were transfused intraoperatively, resulting in no adverse reactions.
CONCLUSION
The c.700 C > G mutation on exon 7 is the molecular basis for the formation of B(A)02, and pedigree analysis shows that the B(A)02 allele was inherited from the proband's maternal grandmother to the proband's mother and then to the proband, showing a stable cis-inheritance pattern rather than a spontaneous mutation. For patients with B(A)02 subtype, type O washed red blood cells and type AB plasma can be transfused according to the principle of compatibility.

OBJECTIVE:
This study aims to analyze the influence factors of lower urinary tract symptoms (LUTS) in patients receiving radical prostatectomy for prostate cancer, and to explore effective nursing strategy in order to provide a theoretical basis for improving the postoperative quality of life of patients.
METHODS:
A retrospective study was conducted on 103 elderly male patients who underwent radical prostatectomy for prostate cancer in the Department of Urology at General Hospital of Eastern Theater Command from August 2022 to August 2024. The patients were categorized into two groups based on whether LUTS occurred. Demographic and clinical characteristics, perioperative parameters, follow-up data, and participation in pelvic floor muscle training were analyzed to identify risk factors associated with postoperative LUTS.
RESULTS:
The incidence of postoperative LUTS in the patients with LUTS before the operation was significantly higher than that in the patients without LUTS before the operation (68.42% vs 32.61%, P=0.001). Additionally, the use of larger catheters (22F) was closely associated with an increased incidence of postoperative LUTS(P<0.01). Pelvic floor exercises demonstrated a significant protective effect, with patients who engaged in pelvic floor exercises exhibiting a lower incidence of postoperative LUTS (38.60% vs 60.87%, P=0.040). Regression analysis further revealed that pelvic floor exercises was the protective factor for postoperative LUTS (OR=0.215, 95%CI: 0.091-0.508, P<0.01).
CONCLUSION
Preoperative LUTS and catheter size are significant risk factors for the occurrence of postoperative LUTS following radical prostatectomy. Pelvic floor muscle exercise after surgery has a protective effect. Postoperative personalized nursing interventions are necessary for different patients to achieve optimal recovery outcomes.

The underlying cause of low response rates to existing immunotherapies is that tumor cells dominate tumor immune escape through surface antigen deficiency and inducing tumor immunosuppressive microenvironment (TIME). Here, we proposed an in situ tumor cell engineering strategy to disrupt tumor immune escape at the root by restoring tumor cell MHC-I/tumor-specific antigen complex (MHC-I/TSA) expression to promote T-cell recognition and by silencing tumor cell CD55 to increase the ICOSL+ B-cell proportion and reverse the TIME. A doxorubicin (DOX) and dual-gene plasmid (MAC pDNA, encoding both MHC-I/ASMTNMELM and CD55-shRNA) coloaded drug delivery system (LCPN@ACD) with tumor targeting and charge/size dual-conversion properties was prepared. LCPN@ACD-induced ICD promoted DC maturation and enhanced T-cell activation and infiltration. LCPN@ACD enabled effective expression of MHC-I/TSA on tumor cells, increasing the ability of tumor cell recognition and killing. LCPN@ACD downregulated tumor cell CD55 expression, increased the proportion of ICOSL+ B cells and CTLs, and reversed the TIME, thus greatly improving the efficacy of αPD-1 and CAR-T therapies. The application of this in situ tumor cell engineering strategy eliminated the source of tumor immune escape, providing new ideas for solving the challenges of clinical immunotherapy.

Attention deficit hyperactivity disorder (ADHD), a prevalent neurodevelopmental disorder influenced by both genetic and environmental factors, remains poorly understood regarding how its polygenic risk score (PRS) impacts functional networks and symptomology. This study capitalized on data from 11,430 children in the Adolescent Brain Cognitive Development study to explore the interplay between PRSADHD, brain function, and behavioral problems, along with their interactive effects. The results showed that children with a higher PRSADHD exhibited more severe attention deficits and rule-breaking problems, and experienced sleep disturbances, particularly in initiating and maintaining sleep. We also identified the central executive network, default mode network, and sensory-motor network as the functional networks most associated with PRS and symptoms in ADHD cases, with potential mediating roles. Particularly, the impact of PRSADHD was enhanced in children experiencing heightened sleep disturbances, emphasizing the need for early intervention in sleep issues to potentially mitigate subsequent ADHD symptoms.

OBJECTIVE:
To explore and quantify the association of hot night exposure during the sperm development period (0-90 lag days) with semen quality.
METHODS:
A total of 6,640 male sperm donors from 6 human sperm banks in China during 2014-2020 were recruited in this multicenter study. Two indices (i.e., hot night excess [HNE] and hot night duration [HND]) were used to estimate the heat intensity and duration during nighttime. Linear mixed models were used to examine the association between hot nights and semen quality parameters.
RESULTS:
The exposure-response relationship revealed that HNE and HND during 0-90 days before semen collection had a significantly inverse association with sperm motility. Specifically, a 1 °C increase in HNE was associated with decreased sperm progressive motility of 0.0090 (95% confidence interval [ CI]: -0.0147, -0.0033) and decreased total motility of 0.0094 (95% CI: -0.0160, -0.0029). HND was significantly associated with reduced sperm progressive motility and total motility of 0.0021 (95% CI: -0.0040, -0.0003) and 0.0023 (95% CI: -0.0043, -0.0002), respectively. Consistent results were observed at different temperature thresholds on hot nights.
CONCLUSION
Our findings highlight the need to mitigate nocturnal heat exposure during spermatogenesis to maintain optimal semen quality.

AIM: To compare the outcome of C3F8 versus silicone oil tamponade after pars plana vitrectomy(PPV)and inverted internal limiting membrane(ILM)for the treatment of highly myopic macular hole retinal detachment(MHRD).METHODS: Retrospective clinical study. Totally 45 patients(45 eyes)with highly myopic MHRD who visited our hospital between January 2019 and August 2022 were selected as the research subjects. The patients were divided into two groups according to different intraocular tamponade agents: C3F8(22 eyes)and silicone oil(23 eyes)groups. All patients underwent conventional three-incision PPV, ILM was tamped, a venous blood clot was placed on the tamped ILM, and 15% C3F8 and silicone oil were used as tamponade, respectively. The best corrected visual acuity(BCVA), multifocal electroretinogram(mfERG), the closure of the macular hole, retinal reattachment and the complications were observed.RESULTS: The macular hole closure rate was 77% in the C3F8 group and 83% in the silicone oil group, respectively(P>0.05), and retinal reattachment rates were 95% and 96%, respectively(P>0.05). The visual acuity of the two groups significantly improved, which was 0.99±0.34 and 1.22±0.37, respectively, and the C3F8 group was better than that of the silicone oil group(t=-2.156, P=0.037). After operation, the response density of the first ring of P1 wave in the first order kernel in mfERG was 114.27±26.37 nV/deg2 for the C3F8 group and 98.08±24.36 nV/deg2 for the silicone oil group, and the response density of the second ring of P1 wave was 80.45±14.94 nV/deg2 for the C3F8 group and 67.73±15.33 nV/deg2 for the silicone oil group, all of which were significantly higher compared to pre-operation [the response density of the first ring of P1 wave: 58.13±13.96 nV/deg2 for the C3F8 group and 55.30±10.48 nV/deg2 for the silicone oil group, the response density of the second ring of P1 wave: 51.18±8.19 nV/deg2 for the C3F8 group and 47.43±11.97 nV/deg2 for the silicone oil group](all P<0.05). It was found that the response density of the first ring of P1 wave was lower in the silicone oil group than in the C3F8 group(P<0.05). There was no statistically significant difference in the incidence of complications between the two groups(P>0.05).CONCLUSION: Silicone oil tamponade or C3F8 tamponade after PPV combined with ILM can both promote retinal reattachment and macular hole closure in patients with MHRD, and the C3F8 tamponade was superior to silicone oil in visual function recovery.

Objective:To observe the effects of kidney-tonifying and mind-calming acupuncture therapy on sleep,mood,sex hormone levels,and traditional Chinese medicine(TCM)symptoms in patients with perimenopausal insomnia(PMI). Methods:A total of 90 patients with PMI were randomly divided into a treatment group and a control group,with 45 cases in each group.Patients in the treatment group were treated with acupuncture at Shenshu(BL23),Taixi(KI3),Baihui(GV20),and Anmian(Extra).The control group was treated with sham acupuncture.Both groups were treated 3 times a week for 4 weeks.Pittsburgh sleep quality index(PSQI)and insomnia severity index(ISI)were used to evaluate the sleep quality of the subjects before treatment,after treatment,and 1 month after treatment(follow-up).Beck depression inventory(BDI)and Beck anxiety inventory(BAI)were used to evaluate the depression and anxiety of the subjects before treatment,after treatment,and at 1-month follow-up.The TCM symptom scale was used to evaluate the TCM symptoms of the subjects before treatment,after treatment,and 1 month after treatment.Serum levels of estradiol(E2),follicle-stimulating hormone(FSH),and luteinizing hormone(LH)were measured before and after treatment. Results:During the study,2 cases dropped out of the treatment group,and no cases dropped out of the control group.The PSQI scores of the treatment group were significantly lower after treatment and at 1-month follow-up compared with those before treatment(P<0.05),and the difference was statistically significant compared with that of the control group(P<0.05).In the control group,the PSQI score was significantly lower after treatment compared with before treatment(P<0.05),and the difference was not statistically significant at 1-month follow-up compared with before treatment(P>0.05).Compared with the pre-treatment,the ISI,BDI,BAI,and TCM symptom scale scores of the treatment group were lower after treatment and at 1-month follow-up(P<0.05),and the differences with the control group at the same time point were statistically significant(P<0.05).The differences in ISI,BDI,BAI,and TCM symptom scale scores of the control group before treatment,after treatment,and at 1-month follow-up were not statistically significant(P>0.05).After treatment,the serum E2 level in the treatment group was significantly higher than that before treatment(P<0.05),and the difference with the control group was statistically significant(P<0.05).The difference in the serum E2 level before and after treatment in the control group was not statistically significant(P>0.05).The differences in the serum FSH and LH levels between before and after treatment were not statistically significant in either group of subjects(P>0.05). Conclusion:Kidney-tonifying and mind-calming acupuncture therapy can improve sleep quality,relieve anxiety and depression,delay the decrease of serum E2 level,and improve related TCM symptoms in patients with PMI.
