Objectives:
. This study aimed to explore the role of the Pcdh15 gene in hearing maintenance and to examine the effects of its deficiency on cochlear structure, cochlear function, and hearing loss in mice.
Methods:
. CRISPR/Cas9 technology was used to generate Pcdh15 knockout (KO) mice. Auditory function was evaluated using hearing tests, while histological approaches were employed to assess morphological changes in cochlear hair cells and spiral ganglion neurons (SGNs). RNA sequencing (RNA-seq) was performed on cochlear tissue from postnatal day 18 (P18) wild-type (WT) and Pcdh15 KO mice to identify differentially expressed genes (DEGs). These DEGs were subjected to functional annotation and pathway analysis, with particular emphasis on oxidative phosphorylation (OXPHOS). Reactive oxygen species (ROS) levels were quantified using flow cytometry and DCFH-DA assays.
Results:
. Pcdh15 KO mice exhibited progressive sensorineural hearing loss, which worsened to profound deafness by P18. Notably, cochlear hair cells and SGNs showed substantial loss and pronounced morphological abnormalities, particularly within the basal high-frequency region. RNA-seq analysis identified 1,359 DEGs, including 1,024 downregulated and 335 upregulated genes. Pathway analysis indicated that Pcdh15 deficiency was associated with inhibition of the OXPHOS pathway, potentially disrupting mitochondrial respiratory chain complexes I, III, IV, and V and thereby impairing energy production and ATP metabolism. In addition, early-stage cochleae from KO mice demonstrated elevated ROS levels and increased oxidative stress, suggesting that redox imbalance may contribute to hearing damage.
Conclusion
. Pcdh15 plays a critical role in hearing maintenance. Its deficiency is associated with severe hearing loss and marked cochlear abnormalities, which are linked to inhibition of OXPHOS, disruption of energy metabolism, and exacerbation of oxidative stress. Together, these findings provide new insights into the mechanisms underlying hearing loss and suggest potential targets for therapeutic intervention.

Objective To systematically evaluate the efficacy and safety of traditional Chinese medicine (TCM) compound in treating pulmonary nodules, providing evidence-based medical evidence for TCM intervention in pulmonary nodules. Methods Computer search of PubMed, CNKI, Wanfang, VIP, and SinoMed was conducted to select randomized controlled trials (RCTs) of TCM compound intervention in pulmonary nodules, with the retrieval time from the inception to November 29, 2023. The Cochrane bias risk assessment tool was used to evaluate the quality of the included studies, and Review Manager 5.4 was used for Meta-analysis. Results A total of 18 RCTs were included, covering 8 provinces across the country, with a total sample size of 1301 patients. The TCM compounds used in the included studies all incorporated the method of dissolving phlegm and dissipating nodules. There was a high risk of bias uncertainty in the included studies. Meta-analysis results suggested that TCM compound could significantly reduce the diameter of pulmonary nodules [MD=−1.41, 95%CI (−1.70, −1.13), P<0.001], decrease the number of nodules [MD=−0.37, 95%CI (−0.73, −0.01), P=0.05], alleviate clinical symptoms [MD=−4.84, 95%CI (−6.04, −3.64), P<0.001], and improve lung function [forced expiratory volume in one second (FEV1), MD=0.55, 95%CI (0.09, 1.01), P=0.02; FEV1/forced vital capacity, MD=6.12, 95%CI (4.47, 7.78), P<0.001]. However, there was no statistically significant difference in the probability of malignancy between the experimental group and the control group [MD=−0.01, 95%CI (−0.01, 0.00), P=0.09]. Conclusion TCM compound can significantly reduce the diameter of pulmonary nodules, decrease the number of nodules, alleviate clinical symptoms, and improve lung function, but future multicenter, large-sample, high-quality RCTs are still needed to further explore and verify this conclusion.

Background:
s/Aims: Non-invasive models stratifying clinically significant portal hypertension (CSPH) are limited. Herein, we developed a new non-invasive model for predicting CSPH in patients with compensated cirrhosis and investigated whether carvedilol can prevent hepatic decompensation in patients with high-risk CSPH stratified using the new model.
Methods:
Non-invasive risk factors of CSPH were identified via systematic review and meta-analysis of studies involving patients with hepatic venous pressure gradient (HVPG). A new non-invasive model was validated for various performance aspects in three cohorts, i.e., a multicenter HVPG cohort, a follow-up cohort, and a carvediloltreating cohort.
Results:
In the meta-analysis with six studies (n=819), liver stiffness measurement and platelet count were identified as independent risk factors for CSPH and were used to develop the new “CSPH risk” model. In the HVPG cohort (n=151), the new model accurately predicted CSPH with cutoff values of 0 and –0.68 for ruling in and out CSPH, respectively. In the follow-up cohort (n=1,102), the cumulative incidences of decompensation events significantly differed using the cutoff values of <–0.68 (low-risk), –0.68 to 0 (medium-risk), and >0 (high-risk). In the carvediloltreated cohort, patients with high-risk CSPH treated with carvedilol (n=81) had lower rates of decompensation events than non-selective beta-blockers untreated patients with high-risk CSPH (n=613 before propensity score matching [PSM], n=162 after PSM).
Conclusions
Treatment with carvedilol significantly reduces the risk of hepatic decompensation in patients with high-risk CSPH stratified by the new model.

Objective:To analyze the effects of parenting care map of premature infants on parenting competence and parenting stress of primipara, with a view to providing a theoretical basis for the development, implementation and modification of clinical interventions.Methods:Convenient sampling method was used to select primigravid women who gave birth in Lishui Maternal and Child Health Hospital from January 2023 to January 2024 for randomized controlled study, which was divided into the observation group and the control group according to the random number table. The control group received routine nursing, and the observation group guided the parents of premature infants to draw the child care map together on the basis of the control group. The scores of Chinese version of parenting sense of competence scale ( C-PSOC ) and Chinese version of Simplified Parenting Stress Index ( PSI-SF ) before and after intervention were compared.Results:A total of 120 cases of primiparous women who met the inclusion and exclusion criteria were enrolled, 60 cases in the control group and 60 cases in the observation group. The age of the control group was (26.25 ± 3.93) years, and the age of the observation group was (25.86 ± 4.22) years. Before the intervention, the difference between the C-PSOC dimension scores and total scores, PSI-SF dimension scores and total scores of the 2 groups was not statistically significant (all P>0.05). After the intervention, the maternal C-PSOC efficacy, satisfaction dimension scores and total scores of primiparous women in the observation group were (32.05 ± 6.27), (40.29 ± 8.19), and (72.23 ± 9.39) points, respectively, which were higher than those of the control group, which were (28.46 ± 6.47), (37.08 ± 8.06), and (65.53 ± 10.24) points, and the differences between the 2 groups were all statistically significant ( t = 3.09, 2.16, 3.74, all P<0.05). After the intervention, the PSI-SF scores and total scores of primiparous women in the observation group on the dimensions of parental distress, personal interaction disorder, and difficult child were (24.43 ± 5.44), (27.51 ± 6.53), (29.47 ± 5.82), and (81.54 ± 10.38) points, respectively, which were lower than those of the control group (28.57 ± 5.52), (30.19 ± 7.02), (32.78 ± 5.37), and (90.97 ± 10.12) points, and the differences between the 2 groups were all statistically significant ( t = 4.41, 2.17, 3.23, 5.04, all P<0.05). Conclusions:Premature child care map can effectively improve the parenting sense of competence of primiparas and reduce their parenting pressure. It is a convenient and effective nursing intervention tool.
