Objective:To explore the chain mediating effect of coping style and illness perception between intolerance of uncertainty and fear of disease progression in patients with intracranial aneurysm.Methods:A total of 270 patients with intracranial aneurysms admitted to the neurosurgery department of 2 hospitals in Guangzhou from October 2023 to June 2024 were selected by convenience sampling method. The general information questionnaire, intolerance of uncertainty scale-12, the brief disease perception questionnaire, medical coping mode questionnaire(MCMQ) and fear of progression questionnaire-short form were used to investigate the subjects. Statistical description and Spearman correlation analysis were performed using IBM SPSS 25.0 software, and AMOS 23.0 software was used to test and correct the structural equation models.Results:The total score of fear of disease progression in patients with intracranial aneurysms was 27.50(20.00, 34.00). The total score of intolerance of uncertainty was 23.50(19.75, 29.00). The sores of confrontation, avoidance and submission in MCMQ were 18.69±5.44, 12.00(10.00, 15.00) and 7.00(5.00, 9.00), respectively.The total score of illness perception was 37.23±11.60. Fear of disease progression was positively correlated with intolerance of uncertainty, submission and illness perception ( r=0.614, 0.696, 0.680, all P<0.01). The direct effect of intolerance of uncertainty on fear of disease progression was significant in patients with intracranial aneurysms ( β=0.431, P<0.001). Intolerance of uncertainty indirectly affected fear of disease progression through submission ( β=0.181, P<0.001) and illness perception ( β=0.092, P<0.001). Submission and illness perception played chain-mediating effect in the relationship between intolerance of uncertainty and fear of disease progression ( β=0.103, P<0.001). Conclusion:The intolerance of uncertainty in patients with intracranial aneurysms can positively predict the fear of disease progression. Submission and illness perception played a chain mediating role between intolerance of uncertainty and fear of disease progression in patients with intracranial aneurysms.

Objective:To explore the current situation and influencing factors of home care needs of primary caregivers of stroke patients based on the existence-relatedness-growth (ERG) need theory, so as to provide reference for the development of effective intervention programs in the future.Methods:The supplemental sequential mixed methods design was adopted. From December 2023 to June 2024, convenience sampling was used to select the primary home caregivers ( n=210) of stroke patients as study subjects in community health service centers in Guangzhou. The survey was conducted using the General Information Questionnaire, Barthel Index, and Professional Care Needs Questionnaire for Family Caregivers of Stroke. Multiple linear regression was used to analyze the influencing factors of home care need scores. In July 2024, 11 primary home caregivers of stroke patients were selected for semi-structured interviews using purposive sampling method. NVivo14.0 software was used for data storage and processing, and Colaizzi 7-step method was used for extracting and summarizing interview data. Results:In the quantitative study, 210 questionnaires were distributed and 202 were effectively collected, with an effective response rate of 96.19%. The total score for home care needs of 202 primary caregivers was (117.31±13.64). Multiple linear regression analysis showed that patients' marital status, history of falls, activities of daily living, caregiver's educational level, average daily caregiving time, and number of caregivers were the influencing factors of home care need score ( P<0.05). In the qualitative study, three themes were distilled, namely the need for disease knowledge and rehabilitation skills, the need for emotional and psychological interventions, and the need for social resource utilization and economic support. Integrating the results of quantitative and qualitative studies revealed that primary caregivers of stroke patients were characterized by congruence, complementarity, and expansiveness in the three dimensions of ERG needs, respectively. Conclusions:The home care needs of primary caregivers of stroke patients present multidimensional and hierarchical characteristics and are influenced by multiple factors such as the functional status of the patients and the characteristics of the caregivers. The quality of community care services should be strengthened, community resource allocation should be optimized, and training programs based on the hierarchy of needs should be constructed to meet the home care needs of primary caregivers of stroke patients.

Objective To investigate the therapeutic efficacy of granulocyte colony-stimulating factor in combination with tadalafil in patients with thin endometrium undergoing artificial cycle frozen-thawed embryo transfer(FET).Methods A prospective randomized clinical trial was conducted involving sixty patients with thin endo-metrium who underwent artificial cycle FET at the Reproductive Center of Qinhuangdao First Hospital between January 2021 and October 2023.The patients were randomly assigned to two groups:the control group(n=30)received tadalafil,while the study group(n=30)received granulocyte colony-stimulating factor in addition to tadalafil.Endometrial ultrasound characteristics,uterine artery blood flow parameters,and pregnancy outcomes were compared between the two groups before and after treatment.Results Before treatment,no significant differ-ences were observed between the research group and the control group in terms of endometrial thickness or endome-trial volume(P>0.05).Ultrasound assessments were repeated after 8 and 14 days of treatment.Compared with baseline measurements,both endometrial thickness and volume exhibited significant increases in both groups(all P<0.05).By day 14 post-treatment,the research group demonstrated significantly greater endometrial thickness and volume compared to the control group(P<0.05).With regard to endometrial patterns,no significant differences were noted between the two groups prior to treatment(P>0.05).After 14 days of treatment,the proportion of patients exhibiting a Type A endometrial pattern in the research group was significantly higher than that in the control group(P<0.05).Prior to treatment,no statistically significant differences were observed between the two groups in terms of pulsatility index(PI),resistance index(RI),systolic/diastolic ratio(S/D),vascularization index(VI),flow index(FI),or Vascularization Flow Index(VFI)(all P>0.05).Following 14 days of treatment,both groups showed significant increases in VI,FI,and VFI compared to baseline values(all P<0.05),along with significant reductions in PI,RI,and S/D(all P<0.05).At 14 days post-treatment,the S/D ratio in the research group was significantly lower compared to the control group,while the VFI was significantly higher(P<0.05).However,statistical analysis showed no significant differences between the two groups in terms of embryo implanta-tion rate,clinical pregnancy rate,early miscarriage rate,and live birth rate(P>0.05).Conclusion For patients with thin endometrium undergoing FET,the combination of granulocyte colony-stimulating factor and tadalafil is more effective than tadalafil alone in improving endometrial receptivity and uterine blood perfusion.

Objective:To investigate the correlation between transabdominal bowel ultrasongraphy (TBUS) parameters and disease activity of ulcerative colitis (UC).Methods:The results of TBUS, endoscopy and laboratory tests of 68 UC patients (108 examinations) who visited the Department of Gastroenterology of the Second Hospital (Eastern Campus) of Hebei Medical University From January 2022 to February 2024 were retrospectively analyzed. According to Mayo endoscopic score (MES), there were 10 cases of remission (MES=0) and 98 cases of active phase (MES>0); patients in active phase further classified into 16 cases of mild (MES=1), 19 cases of moderate (MES=2), and 63 cases of severe (MES=3). The TAUS parameters were compared between patients in remission and active phases. Spearman rank correlation analysis was used to analyze the correlation between the TBUS parameters including bowel wall thickness (BWT), Limberg score, wall layer stratification, fat wrapping and endoscopic activity score, laboratory inflammatory indicators. Receiver operating characteristic curve (ROC) analysis was applied to evaluate the predictive efficacy of the TBUS parameters and laboratory inflammatory indicators in identifying remission under endoscopy. Independent sample t-test and Fisher′s exact probability method were used to compare the two groups. Results:The BWT of patients in remission was significantly thinner than that of patients in active phase ((2.99±0.41) mm vs. (5.66±1.57) mm, t=-5.34, P<0.001). The proportions of patients in remisson with Limberg score ≤2, normal wall layer stratification, and absence of fat wrapping were significantly higher than those of patients in active phase (10/10 vs. 34/98, 10/10 vs. 48/98, 10/10 vs. 41/98, Fisher′s exact test, P<0.001, =0.002, =0.001). BWT, Limberg score, wall layer stratification, and fat wrapping were positively correlated with MES ( r=0.676, 0.677, 0.441, and 0.493, all P<0.001). BWT and Limberg score were moderate positively correlated with C-hypersensitive reactive protein, erythrocyte sedimentation rate and fecal calprotectin (BWT: r=0.561, 0.420 and 0.458, all P<0.001; Limberg score: r=0.576, 0.469 and 0.403, all P<0.001), and were negatively correlated with serum albumin and hemoglobin (BWT: r=-0.604 and -0.453, both P<0.001; Limberg score: r=-0.573 and -0.532, both P<0.001). The results of ROC analysis showed that BWT achieved the best predictive efficacy in identifying endoscopic remission, and the best cut-off value was 3.45 mm (area under the curve was 0.972, 95% confidence interval: 0.944 to 1.000, P<0.001), with a sensitivity of 93.9% and specificity of 100.0%. Conclusions:TBUS parameters can accurately reflect disease activity in UC. It is a powerful tool for UC monitoring. The BWT<3.45 mm is the best cut-off value in prediction of endoscopic remission.

Objective:To investigate the impact of intraoperative multimodal neurophysiological monitoring combined with blood pressure precise control on incidence of acute cerebral infarction after carotid endarterectomy.Methods:A retrospective study was peformed; 305 patients with atherosclerotic stenosis of the carotid artery admitted to and accepted carotid endarterectomy in Department of Vascular Neurosurgery, Dong'e County People's Hospital from January 2020 to September 2023 were selected. Intraoperative multimodal neurophysiological monitoring combined with traditional empirical modalities for blood pressure control was applied to 153 patients admitted to our hospital from January 2020 to December 2021 (control group), and intraoperative multimodal neurophysiological monitoring combined with blood pressure precise control (based on monitored sensory or motor wave amplitude changes) was applied to 152 patients admitted to our hospital from January 2022 to September 2023 (experimental group). Difference in postoperative acute cerebral infarction incidence between the 2 groups was compared.Results:The experimental group had significantly lower postoperative acute cerebral infarction incidence compared with the control group (4.6% vs. 13.0%, P<0.05). The experimental group had significantly lower postoperative asymptomatic acute cerebral infarction incidence compared with the control group (3.3% vs. 9.8%, P<0.05), while no significant difference was noted in postoperative symptomatic acute cerebral infarction incidence between the 2 groups ( P>0.05). Conclusion:Intraoperative multimodal neurophysiological monitoring combined with blood pressure precise control can reduce the postoperative acute cerebral infarction incidence in patients accepted carotid endarterectomy, especacailly postoperative asymptomatic acute cerebral infarction incidence, thereby enhancing surgical safety.

Objective To investigate the effects of granulocyte colony-stimulating factor(G-CSF)combined with tadalafil(TD)on endometrial receptivity and pregnancy outcomes in patients with thin endometrium(TE).Methods Patients with TE in the department of reproductive medicine of the First Hospital of Qinhuangdao from May 2020 to March 2023 were selected as the study subjects.They were divided into a experimental group(G-GSF combined with TD)and a control group(G-GSF)according to the different treatment regimens.The endometrial receptivity[endometrial thickness(EMT),endometrial volume(EMV),endometrial blood flow peak systolic flow rate/end diastolic flow rate(EBF-S/D),endometrial fractionation,endometrial blood flow fractionation,uterine artery pulsatility index(AUPI),uterine artery resistance index(AURI)and uterine arterial peak systolic flow rate/end diastolic flow rate(AU-S/D)]of the TE patients before and after treatment(the endometrial transition day)were compared;the endometrial receptivity on endometrial transformation day,post-treatment pregnancy outcomes[embryo implantation rate(EIR),clinical pregnancy rate(CPR),and early miscarriage rate(ABR)],and the incidence of adverse reactions during treatment were compared between the two groups.Results A total of 60 patients were included in the study,with 30 in each group.Before treatment,the difference in endometrial receptivity between the two groups was not statistically significant(P＞0.05).Compared with the pre-treatment period,the EMT,EMV,the proportion of type A endometrium and the proportion of type Ⅱ+Ⅲ endometrial blood flow significantly increased in the two groups after treatment on the endometrial transformation day increased significantly(P＜0.05),while the EBF-S/D,AUPI,AURI and AU-S/D significantly decreased(P＜0.05).EMT and EMV were greater in the experimental group than in the control group(P＜0.05),whereas EBF-S/D,AUPI,AURI and AU-S/D were less than those in the control group(P＜0.05).Compared with the control group,the differences in the proportion of endometrium,the proportion of endometrial blood flow,EIR,CPR and ABR in the experimental group were not statistically significant(P＞0.05).No adverse reactions occurred during treatment in both groups.Conclusion G-CSF combined with TD can improve endometrial receptivity in TE patients with high safety,but there is no effect on pregnancy outcome.
