Objective:To explore the effects of mindfulness-based decompression therapy on fear of disease progression, quality of life and sleep quality in patients with acute ischemic stroke, in order to provide intervention measures to alleviate fear of the disease progression degree and improve sleep and quality of life in patients with acute ischemic stroke.Methods:This study was a randomized controlled study. Using the convenience sampling method, 98 patients with acute ischemic stroke who attended the Department of Neurology at the Third Hospital of Hebei Medical University from November 2021 to September 2022 were selected for the study, and the study population was divided into experimental group ( n=49) and control group ( n=49) using the random number table method. The control group received conventional care, and the experimental group received mindfulness-based stress reduction therapy for 8 weeks in addition to conventional care. Compared the scores of the Fear of Progression Questionnaire-Short Form (FoP-Q-SF), Stroke-Specific Quality of Life Scale (SS-QOL), and Pittsburgh Sleep Quality Index (PSQI) between the two groups of patients before and after intervention using two independent sample t-tests, and further compared the score spread of each scale before and after intervention between the two groups of patients using Mann-Whitney U test. Results:In the experimental group, 4 cases fell off and 3 cases had imperfect questionnaire information, while in the control group, 2 cases fell off and 5 cases had imperfect questionnaire information. Finally, 42 cases were included in each group. The 23 males and 19 females in the control group aged (48.31 ± 7.61) years old, while 25 males and 17 females in the experimental group aged (50.19 ± 8.64) years old. There was no significant difference in FoP-Q-SF, SS-QOL and PSQI scores between the two groups before intervention (all P>0.05). After intervention, the scores of FoP-Q-SF and PSQI in the experimental group (35.79 ± 7.04, 7.19 ± 2.58) were lower than those in the control group (38.52 ± 4.02, 9.45 ± 2.28), while the SS-QOL score (200.36 ± 21.75) was higher than that in the control group (185.41 ± 15.90), the differences were statistically significant ( t=2.19, -4.26, 3.60, all P<0.05). After intervention, the scores of FoP-Q-SF and PSQI in the experimental group were lower than those before intervention (39.69 ± 4.15, 10.00 ± 2.85), while the SS-QOL score was higher than that before intervention (176.93 ± 23.54), the differences were statistically significant ( t=4.80, 10.45, -11.43, all P<0.05). The score spreads of FoP-Q-SF, SS-QOL, and PSQI in the experimental group before and after intervention were 1.00 (0.00, 9.25), 20.00 (12.75, 32.75), 3 (1, 4), which were higher than 1.00 (-1.25, 2.00), 5.50 (1.00, 10.25), 0 (-1, 2) in the control group, the differences were statistically significant ( Z=-2.30, -5.74, -5.53, all P<0.05). Conclusions:Mindfulness-based decompression therapy can effectively relieve the fear of disease progression and improve the quality of sleep and life in patients with acute ischemic stroke.

Objective:To explore the potential of integrating virtual surgery with three-dimensional (3D) printed guides in the surgical management of mandibular benign tumors and subsequent reconstruction of bone defects.Methods:A retrospective analysis was conducted on the clinical data of patients who underwent computer-assisted resection and vascularized fibular flap reconstruction for benign mandibular tumors at the Department of Oral and Maxillofacial Surgery, First Affiliated Hospital of Zhengzhou University, from June 2013 to December 2020. According to the utilization of guide plates for mandibular and fibular osteotomy during surgical procedures or not, the patients were categorized into two cohorts: a guide plate cohort and a non-guide plate cohort. In the guide plate group, custom-designed gudie plates based on virtual surgical plans were fabricated using 3D printing technology and employed intraoperatively; In the non-guide plate group, surgery was exclusively performed based on virtual surgical plan and prebent titanium plate without any supplementary plating. The measured outcomes included fibular flap osteotomy, operation duration, and clinical flap survival. Computed tomography images obtained one week post-surgery were utilized to assess the intersegmental commissure degree between fibular segments as well as between fibular segments and mandible, commissure degree between fibular segments and prebent titanium plate, and condyle position. The satisfaction of patients with their facial appearance was evaluated 6 months after the surgery using a visual analogue scale. Statistical analysis was conducted using SPSS 21.0 software. Independent sample t-tests was utilized to compare the duration of operation and and postoperative evaluation of facial appearance, the Chi-square tests was utilized for condyle position, commissure degrees among interactions involving fibular segments, prebent titanium plates, bone segments( P<0.05 denoted statistical significance). Results:A total of 30 patients were enrolled, comprising 17 males and 13 females, with a median age of 24 years (16-64 years). The preparation process of fibular flaps proceeded smoothly. The required length of fibula was measured as (14.1 ± 1.9) cm (5.7-18.1 cm), while the number of fibular segments ranged from 2 to 4, averaging at approximately 2.9 ± 0.6. The mandibular defects were repaired using a single-layer fibula in 12 cases, a vascularized folded fibula in 7 cases and a combination of vascularized and non-vascularized fibula in 11 cases. The operation time for the guide plate group was recorded as ( 335.9 ± 64.0) min (240-433 min), while it was observed to be (470.7 ± 140.5 ) min (280-680 min) for the non-guide plate group.The postoperative follow-up duration ranged from 9 to 23 months, with an average period of 11 months. All fibular flaps demonstrated clinical survival. The number of patients with good commissure degree between fibular and mandibular segments, between prebent titanium plate and fibular and mandibular segments and the position of condyle were 15, 15 and 13 cases in guide plate group, 10, 13 and 11 cases in non-guide plate group respectively. The statistical analysis revealed a significant difference ( P<0.05) in the degree of commissure between the fibular and the mandibular segments (15/15 vs. 10/15) in the two groups. Both groups exhibited high levels of satisfaction regarding their postoperative facial appearance at the 6 months follow-up, observed to be 9.6±0.5 and 9.3±0.5 respectively, and the statisticla analysis revealed non-significant difference ( P>0.05). Conclusion:The integration of virtual surgery with 3D printed guide plates can effectively reduce operative time and improve precision in the repair and reconstruction of free-fibular flaps following resection of benign tumors of the mandible.

With the increasing life expectancy and lifestyle changes of patients with chronic hepatitis B (CHB), the significance of comorbidities of chronic non-communicable diseases (NCDs) in disease progression and health prognosis of CHB patients is gaining prominence. This study aims to explore the association between CHB and NCDs comorbidities, focusing on the impact of common metabolism-related diseases, such as metabolic syndrome and diabetes, on the health outcomes of CHB patients. We also summarize studies on integrating the management of comorbidities in CHB patients and provide relevant recommendations for effective management. The findings of this study serve as a foundation for understanding the clinical characteristics and prevalence trends, reducing the disease burden of comorbidities among CHB patients, and establishing a comprehensive and coordinated management system for comorbidities.

Objective:To search, review and summarize the best evidence on promoting maturation of autologous arteriovenous fistula (AVF) in patients undergoing maintenance hemodialysis (MHD) .Methods:In accordance with the relevant methods of evidence-based nursing, evidence was retrieved from relevant websites and databases according to the "6S" pyramid model, including clinical decision-making, guidelines, expert consensus, group standards, and systematic reviews. The search time limit was from April 20, 2012 to April 20, 2022. Two investigators assessed the quality of the evidence, and the evidence team extracted and summarized the evidence.Results:A total of 17 articles were included, including 1 clinical decision-making, 6 guidelines, 1 expert consensus, 1 group standard and 8 systematic reviews. Totally 28 best evidences were summarized from 6 aspects: team education, perioperative management, functional exercise, physical therapy, drug application, first puncture timing and scheme.Conclusions:The best evidence provides a reference for medical staff to standardize the management of AVF in MHD patients. It is recommended that medical staff develop individualized plans based on medical conditions, clinical judgment, and patient wishes when applying relevant evidence.

Objective:To understand the characteristics of sexualized drug use (SDU) among men who have sex with men (MSM) in Chengdu and classify their behavioral patterns by applying the two-step cluster (TSC) algorithm and by exploring the association between SDU patterns and high risk sexual behaviors, in order to provide a reference basis for the development of HIV prevention interventions.Methods:Supported by an MSM-friendly organization in Chengdu from December 2021 to February 2022, MSM were recruited by on-site survey and peer referral to collect information on sociodemographics, SDU characteristics, sexual behaviors, STD diagnosis, and HIV status. TSC was performed to classify the characteristics of SDU, and the differences between groups were compared. Chi-square test and multiple binary logistic regressions were used to identify the relationship between SDU clusters and HIV-related risk sexual behaviors.Results:A total of 727 MSM were surveyed, and 39.8% (289/727) of the respondents reported SDU experience with a same-sex partner in the last six months. TSC clustered SDU-MSM into three behavioral pattern groups. There were significant differences in monthly income, types of drugs used for SDU, mode, frequency, polydrug use, multiple sexual partners, non-adherence to condom use, and group sex among the three groups of SDU-MSM ( P<0.05). Multivariate binary logistic regression analysis showed that the third category of SDU-MSM was 2.22 (95% CI: 1.06-4.66) times more likely than the first category not to use condoms consistently; the third and second categories were 2.82 (95% CI: 1.18-6.77) times and 8.78 (95% CI: 3.42-22.42) times. Conclusions:The prevalence of SDU among MSM in Chengdu was more than 1/3, and different SDU clustering pattern was associated with high-risk sexual behaviors. MSM with higher SDU frequency, drug use, and polydrug abuse are more difficult to adhere to condom use and more likely to have group sex and high risk sexual behaviors, increasing the risk of STD and HIV infection, and need to strengthen SDU surveillance and intervention.

Objective: To investigate the willingness to use three types of pre-exposure prophylaxis (PrEP) and its associated factors among MSM in Chengdu. Methods: A total of 793 MSM were recruited through Chengdu Tongle Health Consultation Service Centre between November 2021 to January 2022. Data were collected, including demographic characteristics, sexual behaviors in the last six months, PrEP-related stigma, HIV anticipated stigma, MSM internalized stigma, and willingness to use three types of PrEP. Univariate and multivariate logistic regression models were conducted to investigate the associated factors of willingness in using the three types of PrEP. Results: Among 793 participants, willingness to take on-demand PrEP was higher (68.3%). Higher education and multiple sexual partners increased the willingness to use oral PrEP, higher education [compared with junior high school or below, high school or technical secondary school (aOR=2.43, 95%CI: 1.13-5.21), junior college (aOR=2.67, 95%CI: 1.27-5.61), bachelor degree (aOR=3.21, 95%CI: 1.52-6.74), master degree or above (aOR=3.77, 95%CI: 1.54-9.26)], multiple sexual partners (aOR=1.54, 95%CI: 1.12-2.11) were positively associated with daily oral PrEP. HIV anticipated stigma was positively associated with the willingness in using all three types of PrEP: daily oral PrEP (aOR=1.07, 95%CI: 1.02-1.12), on-demand PrEP (aOR=1.09, 95%CI: 1.03-1.15), and injectable PrEP every 8 week (aOR=1.06, 95%CI: 1.01-1.11). Conclusions: The overall willingness in using PrEP in MSM in Chengdu is relatively high, and the promotion of PrEP is highly feasible. In the future, we should continue to promote publicity and education on HIV and PrEP-related knowledge in this population, improve the cognitive level, and guide MSM to establish the correct motivation for PrEP use.
