Analysis of influencing factors of caregiver preparedness at discharge of patients with chronic heart failure based on the individual and family self-management theory / 中国实用护理杂志

Objective:A structural equation model of the influencing factors on caregiver preparedness at discharge of patients with chronic heart failure was constructed based on the individual and family self-management theory, and the main paths influencing caregiver preparedness were explored.Methods:This study was a cross-sectional survey. A total of 345 caregivers of patients with chronic heart failure who were hospitalized in the Fourth Affiliated Hospital of China Medical University from October 2020 to August 2021 were selected as research objects by convenience sampling method, and they were investigated by Caregiver Preparedness Scale, Family APGAR Index, Herth Hope Index, Social Support-Rating Scale, Simplified Coping Style Questionnaire. The influencing factors on caregiver preparedness at discharge of patients with chronic heart failure were analyzed.Results:The total score of Caregiver Preparedness Scale, Family APGAR Index, Herth Hope Index, Social Support-Rating Scale, and Positive and Negative Coping Subscale of Simplified Coping Style Questionnaire in patients with chronic heart failure was (20.79 ± 4.92), (8.05 ± 1.43), (35.34 ± 4.47), (43.89 ± 6.56), (24.38 ± 5.21), (11.21 ± 4.26) points. Caregiver preparedness in patients with chronic heart failure was positively correlated with family function, hope, positive coping and social support ( r values were 0.213-0.383, all P<0.01), and negatively correlated with negative coping ( r=-0.546, P<0.01). Family function and social support in patients with chronic heart failure could directly or indirectly affect caregiver preparedness (total effect value: 0.380, 0.212), hope and negative coping directly affected caregiver preparedness (total effect value: 0.200, -0.433), and could account for 39% of the total variation in caregiver preparedness. Conclusions:Caregiver preparedness of patients with chronic heart failure needs further improvement. The effective ways to improve caregiver preparedness are to pay attention to family function, improve hope level, increase social support and reduce negative coping.

Effects of Bushen Yiqi Huoxue Decoction in Treatment of Patients with Diminished Ovarian Reserve: A Randomized Controlled Trial / 中国结合医学杂志

OBJECTIVE@#To explore the therapeutic effect of Bushen Yiqi Huoxue Decoction BYHD) in patients with diminished ovarian reserve (DOR).@*METHODS@#A total of 180 patients with DOR diagnosed from December 2013 to December 2014 were equally assigned into progynova and duphaston (E+D) group, Zuogui Pill group and BYHD group with 60 cases in each by computerized randomization. Patients received E+D, Zuogui Pill or BYHD for 12 months, respectively. Follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), anti-Müllerian hormone (AMH), antral follicle count (AFC), ovarian volume, endometrial thickness, and the resistance indices (RIs) of ovarian arteries and uterine arteries were observed before and after treatment.@*RESULTS@#Nine women (4 from the E+D group, 3 from the Zuogui Pill group, and 2 from the BYHD group) withdrew from the study. After 6 months, Zuogui Pill and BYHD significantly decreased FSH and LH and increased endometrial thickness and AMH (all P<0.01). BYHD also resulted in E2 elevation (P<0.05), ovary enlargement (P<0.05), AFC increase (P<0.01), and RI of ovarian arteries decrease (P<0.05). After 12 months, further improvements were observed in the Zuogui Pill and BYHD groups (all P<0.01), but BYHD showed better outcomes, with lower FSH, larger ovaries and a thicker endometrium compared with the Zuogui Pill group (all P<0.01). However, E+D only significantly increased endometrial thickness (P<0.01) and no significant improvements were observed in the RI of uterine arteries in the three groups.@*CONCLUSIONS@#BYHD had a favorable therapeutic effect in patients with DOR by rebalancing hormone levels, promoting ovulation, and repairing the thin endometrium. The combination of tonifying Shen (Kidney), benefiting qi and activating blood circulation may be a promising therapeutic strategy for DOR.

Manufacture and application of laparoscopic extraperitoneal sigmoid colostomy / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the safety and feasibility of laparoscopic extraperitoneal sigmoid colostomy.</p><p><b>METHODS</b>Thirty-six patients with low rectal cancer undergoing laproscopic abdominoperineal resection from July 2011 to July 2012 were prospectively enrolled in the study and randomly divided into extraperitoneal colostomy group(EPC, n=18) and internal peritoneal colostomy group(IPC, n=18). Follow-up period was 4-16 (median, 7) months and postoperative complications were compared between two groups.</p><p><b>RESULTS</b>One case in EPC group was converted to IPC because of poor blood supply of the proximal sigmoid, who was eliminated from the subsequent analysis. Compared with the IPC group, the surgery time was longer in EPC group [(25.3±8.5) min vs. (14.7±6.4) min], while the difference was not statistically significant(P>0.05). Each group had 1 case of stoma ischemia, who both received the colostomy reconstructive surgery. The incidence of stoma edema was significantly higher in EPC group[35.3%(6/17) vs. 0, P<0.05). The early postoperative complications rate did not significantly different between the two groups[58.8%(10/17) vs. 27.8%(5/18), P>0.05]. The late postoperative complications rate was 22.2%(4/18) in IPC group, including 1 case of stoma prolapse, 1 case of stoma stenosis and 2 cases of parastomal hernia. No later postoperative complication occurred in EPC group.</p><p><b>CONCLUSION</b>Extraperitoneal sigmoid colostomy is an easy and safe procedure with lower late complications as compared to internal peritoneal sigmoid colostomy.</p>
