Objective To investigate the effect of smoking on the semen quality in infertile men.Methods A total of 360 male infertility patients were enrolled and divided into the smoking group(n=190)and non-smoking group(n=170)based on whether they smoked or not.Furthermore,the smoking group was subdivided into group A(≤10 sticks/d,n=63),group B(11～20 sticks/d,n=80),and group C(>20 sticks/d group,n=47)according to the amount of smoking.Semen volume,liquefaction time,sperm concentration,motility,DNA fragmentation rate and normal morphological rate were observed and compared between and within the groups.Results There were significant differences in semen volume,liquefaction time,sperm motility,normal morphological rate and DNA fragmentation rate between the smoking group and the non-smoking group(P<0.05).The semen volume,sperm motility and normal morphological rate of the smoking group were lower than those in the non-smoking group,and the DNA fragmentation rate and semen liquefaction time were higher than those in the non-smoking group.And with the increase of smoking volume,sperm motility and normal morphological rate decreased,semen liquefaction time and DNA fragmentation rate increased,and there was no significant difference in the sperm concentration between the smoking group and non-smoking group(P>0.05).There was no significant difference in the semen volume between the three groups with different smoking amounts(P>0.05).Conclusion Smoking has a negative impact on the sperm quality parameters such as semen volume,sperm motility,normal morphological rate,sperm motility,liquefaction time and DNA fragmentation,and the effect of heavy smoking is particularly obvious.We should strengthen the comprehensive health education,promote the healthy lifestyles and reduce smoking.

Objective To explore the effect of transcranial direct current stimulation(tDCS)based on music therapy on insomnia. Methods From July,2023 to April,2024,70 patients with insomnia in the Fourth Affiliated Hospital of Soochow Univer-sity were randomly divided into control group(n=35)and observation group(n=35).Both groups accepted mu-sic therapy;moreover,the observation group accepted tDCS,and the control group accepted sham tDCS,for four weeks.They were assessed with Pittsburgh Sleep Quality Index(PSQI)total score and sub-score,Hamilton De-pression Scale 17-item(HAMD-17),Hamilton Anxiety Scale(HAMA),Chinese version of Stress Perception Scale(CPSS);and the relative power of resting-state electroencephalography(EEG)and mean blood flow veloci-ty(Vm)of each cerebral artery with transcranial Doppler were measured before and after treatment. Results Five cases dropped down in the control group,and four in the observation group.PSQI total score and sub-score,HAMD-17 score,HAMA score and CPSS score(|t|>3.503,P<0.01)in the observation group decreased after treatment,and were less in the observation group than in the control group(|t|>2.304,P<0.05),except sleep duration,sleep efficiency and CPSS scores.The relative power of δ and θ increased in the observation group,and decreased in α,β and γ(|t|>6.468,P<0.001),and were better in the observation group than in the control group(|t|>2.395,P<0.05).The Vm of each artery increased in the observation group(|t|>4.624,P<0.001),and were more in the observation group than in the control group(|t|>2.147,P<0.05). Conclusion tDCS based on music therapy may further improve sleep quality and EEG activity,increase cerebral blood flow velocity,and reduce adverse emotions in insomnia patients.

As the largest cancer in the world, breast cancer has both benefits and risks from its diversified treatments. Shared decision-making can respect the patient's right to information and autonomy, consider their preferences and value orientations, and help patients obtain the most suitable treatment plan, it also can reduce their decision-making difficulties and improve their disease knowledge awareness and decision-making satisfaction. This paper reviews the definition of shared decision-making, the influencing factors, steps, tools and clinical effects of shared decision-making in the treatment decision-making of breast cancer patients, in order to provide reference for the research of shared decision-making in breast cancer patients in China.

Purpose: This study identified risk factors for neurogenic lower urinary tract dysfunction (NLUTD) in patients with acute ischemic stroke (AIS) through multidimensional analysis of the medical records of patients, aiming to reduce the incidence of NLUTD, improve prognosis, and facilitate rehabilitation. Materials and Methods: In this case-control study, patients with AIS were recruited from two tertiary general hospitals in Shenzhen, China, from March 2021 to October 2023. Patients were divided into NLUTD and non-NLUTD groups based on the presence and absence of NLUTD, respectively. Comparative analysis was performed using the Mann–Whitney U and chi-square tests, with significant variables being included in logistic regression analysis. Results: Of the 652 participants enrolled in this study, 119 participants (18.3%) developed NLUTD. Bivariate analysis showed that 39 of 54 screened factors exhibited a significant correlation (p<0.05) with the incidence of NLUTD after AIS. Significant variables identified through logistic regression analysis included Glasgow coma scale (GCS) and National Institutes of Health Stroke Scale (NIHSS) scores, anemia, aphasia, pneumonia, brainstem involvement, multiple lesions, urine clarity (CLA), random venous blood glucose (GLU) and hemoglobin (HGB) levels, and white blood cell (WBC) count. Conclusions A total of 11 risk factors for NLUTD were identified in this study. This finding provides valuable guidance for reducing the incidence of NLUTD after AIS and improving the quality of life of patients.

ObjectiveTo explore the possible mechanisms of Tongfengning （痛风宁， TFN） in treating hyperuricemia （HUA） of spleen deficiency with exuberance of dampness syndrome. MethodsTen of 60 mice were randomly selected， and were fed with regular diet as the control group， while the remaining 50 mice were fed with high-fat and high-sugar diet combined with excessive exercise and potassium oxonate-allopurinol suspension to establish an HUA animal model of syndrome of spleen deficiency with exuberance of dampness. After the successful modeling， in order to better observe the effects of TFN on the intestinal microbiota of the model mice， a mixed antibiotic suspension was administered by gavage to induce further dysbiosis of the intestinal microbiota in the model mice. Fifty sucessfully modeled mice were randomly divided into model group， TFN group， allopurinol group， probiotics group， and an allopurinol + probiotics group， 10 in each group. The TFN group was administered TFN liquid at a dosage of 19.11 g/（kg·d） by gavage. The allopurinol group was administered allopurinol suspension at a dosage of 78 mg/（kg·d） by gavage. The probiotics group was administered live combined Bifidobacterium and Lactobacillus tablets suspension at a dosage of 3 g/（kg·d） by gavage. The allopurinol + probiotics group was administered allopurinol at a dosage of 78 mg/（kg·d） and live combined Bifidobacterium and Lactobacillus tablets suspension at a dosage of 3 g/（kg·d） by gavage. The control group and model group were administered normal saline at a dosage of 19.11 ml/（kg·d） by gavage. The interventions were continued for 21 days. In order to maintain a stable high blood uric acid state， all groups but the control group continued modeling while receiving drug intervention. The changes in spleen deficiency syndrome scores， blood uric acid levels， microbial community structure， acetic acid and butyric acid content in intestinal lavage fluid， adenosine deaminase （ADA） and xanthine oxidase （XOD） content in small intestine tissue， as well as ATP-binding cassette transporter G2 （ABCG2）， glucose transporter 9 （GLUT9） protein and mRNA expression in the small intestine tissue were compared among the groups of mice. ResultsCompared with the control group， the model group showed increased spleen deficiency syndrome scores， blood uric acid levels， relative abundance of phylum Firmicutes， Firmicutes/Bacteroidetes ratio， abundance of Bacteroides genus， Klebsiella genus， and Enterococcus genus， acetic acid content in intestinal lavage fluid， ADA and XOD content in small intestine tissue， as well as GLUT9 protein and mRNA expression （P<0.05）. The number of operational taxonomic units （OTUs） of intestinal microbiota， relative abundance of Bacteroidetes phylum， abundance of Lactobacillus genus and uncultured Bacteroides genus， butyric acid content in intestinal lavage fluid， and ABCG2 protein and mRNA expression in small intestine tissue were significantly decreased （P＜0.05）. Compared with the model group， in the group treated with TFN， probiotics， and allopurinol + probiotics， the spleen deficiency syndrome score， blood uric acid level， relative abundance of Firmicutes， acetic acid content in intestinal lavage fluid， ADA and XOD content in small intestine tissue， GLUT9 protein and mRNA expression significantly decreased. The number of gut microbiota OTUs， relative abundance of proteobacteria， butyric acid content in intestinal lavage fluid， ABCG2 protein and mRNA expression in small intestine tissue significantly increased （P＜0.05）. In the probiotics group， the ratio of Firmicutes to Bacteroidetes decreased. In the TFN group， the abundance of Lactobacillus and uncultured Bacteroidetes significantly increased， while the abundance of Parabacteroides， Klebsiella， and Enterococcus significantly decreased （P＜0.05）. Compared with the TFN group， allopurinol group and the probiotics group showed elevated blood uric acid levels， abundance of Bacteroidetes， ADA and XOD levels in intestinal tissue， and GLUT9 mRNA expression. The relative abundance of Firmicutes， abundance of lactobacilli， and ABCG2 mRNA expression significantly decreased. The probiotics group showed elevated GLUT9 protein expression in intestinal tissue. The probiotics group and the allopurinol plus probiotics group showed significantly higher scores for spleen deficiency syndrome in mice， and lower levels of butyric acid in mouse intestinal lavage fluid. The allopurinol group showed decreased numbers of OTUs in mouse intestinal flora， decreased abundance of proteobacteria， and butyric acid levels in intestinal lavage fluid. The allopurinol group also showed decreased ABCG2 protein expression in intestinal tissue， increased acetic acid levels in intestinal lavage fluid， increased abundance of Klebsiella， and significantly elevated GLUT9 protein expression （P＜0.05）. ConclusionsThe treatment of HUA with TFN may be associated with the regulation of intestinal probiotics （such as lactobacilli） and pathogenic bacteria （such as Klebsiella）， as well as the production of bacterial metabolites such as acetic acid and butyric acid. It may also involve reducing the expression of ADA and XOD in the intestines， decreasing intestinal uric acid production， upregulating the expression of intestinal epithelial urate transporter ABCG2， downregulating GLUT9 expression， and promoting intestinal uric acid excretion. These factors are related to the syndrome of spleen deficiency with exuberance of dampness.

Objective:To explore the effect of supportive care in elderly breast cancer patients undergoing chemotherapy.Methods:From October 2020 to October 2021, a total of 66 elderly breast cancer patients undergoing chemotherapy from the First Affiliated Hospital of Dalian Medical University were enrolled as research objects using the convenience sample method, and were divided into the observation group and the control group with 33 cases in each group according to coin toss. The control group received routine nursing, and the observation group received supportive care based on the control group. Supportive care needs, symptom burden, and quality of life scores were compared between the two groups.Results:After intervention, there was no significant difference in sexual need dimension score between the two groups ( P>0.05). After intervention, the scores of physiological and daily life needs, psychological needs, care and support needs, health information needs and total average score of supportive care needs of the observation group were lower than those of the control group, and the differences were statistically significant ( P<0.05). After intervention, the total average score of symptom burden of the observation group was lower than that of the control group, and the difference was statistically significant ( P<0.05). After intervention, the total average score of quality of life of the observation group was higher than that of the control group, and the difference was statistically significant ( P<0.05) . Conclusions:Supportive care can reduce the needs of elderly breast cancer patients undergoing chemotherapy, reduce the burden of symptoms, and improve the quality of life, which is worthy of clinical application.

Objective:To explore the relationship among emotional intelligence, narrative competence, and clinical communication competence of undergraduate nursing students.Methods:From March to April 2022, 211 undergraduate nursing students from two affiliated hospitals of universities in Dalian were selected as the research subject by convenience sampling. The survey was conducted using the General Information Questionnaire, Emotional Self-Awareness Questionnaire (ESQ), Narrative Competence Scale (NCS), and Clinical Communication Competence Scale of the Nursing Students. SPSS 25.0 software and Process 3.1 plugin were used for mediating effect testing. Multiple linear stratified regression analysis was used to test the moderating effects.Results:A total of 211 questionnaires were distributed and 207 valid questionnaires were obtained. Among 207 undergraduate nursing students, the scores of the ESQ, NCS, and Clinical Communication Competence Scale of the Nursing Students were (124.18±13.22), (140.38±18.70), and (82.88±10.43), respectively. The emotional intelligence, narrative competence, and clinical communication competence of undergraduate nursing students were positively correlated ( P<0.05). The narrative competence of undergraduate nursing students played a complete mediating effect between emotional intelligence and clinical communication competence, with the mediating effect accounting for 72.5% of the total effect. The narrative competence of undergraduate nursing students had a moderating effect on emotional intelligence and clinical communication competence ( P<0.01) . Conclusions:The narrative competence of undergraduate nursing students is a mediating and moderating variable between emotional intelligence and clinical communication competence. Nursing educators should develop targeted interventions to improve students' narrative competence and thus enhance their clinical communication competence.
