Objective To explore the effect of interaction model of client health behavior (IMCHB) on self-management ability and quality of life in patients with ulcerative colitis (UC). Methods A total of 84 UC patients hospitalized from June 2016 to January 2018 were enrolled by convenience sampling method. They were randomly divided into observation group and control group with 42 cases in each group. Based on routine drug treatment, the control group received routine nursing intervention, while the observation group applied IMCHB to guide nursing intervention. Before intervention and 3 months after the intervention, the patients' self-management ability was assessed with the Inflammatory Bowel Disease Self-efficacy Scale (IBD-SES) and self-designed Self-Management Behavior Questionnaire, and the patients' quality of life was assessed with the Inflammatory Bowel Disease Questionnaire (IBDQ). Results At the end, 40 cases in the observation group and 41 cases in the control group were included in the study. There was no statistically significant difference in IBD-SES and IBDQ scores between the two groups before intervention (P> 0.05). After intervention, the scores of "stress and emotional management" in IBD-SES scale and "maintenance management in remission period" in observation group were (78.83±10.37), (46.83±3.58) respectively, higher than those in control group [(70.27±10.82), (44.27±3.61)], the scores of systemic symptoms and emotional ability in observation group were (20.25 ±2.68), (60.65±4.24) respectively, higher than those in control group [(18.32±3.01) and (58.37±4.82)]and the differences were statistically significant (P< 0.05). After intervention, the qualified rates of dietary records and exercise records in the observation group were 80.00%(32/40) and 85.00%(34/40), respectively, which were higher than those in the control group [51.22%(31/40) and 60.98%(25/40)] with statistical significance (P<0.05). Conclusions IMCHB can promote the self-management ability and quality of life of UC patients.

Objective:To investigate the current situation and influencing factors of patients′ satisfaction with nursing humanistic care, and to provide reference for improving the quality of such care provided by hospitals.Methods:From July to August 2022, outpatients and inpatients in 30 provinces were selected by multi-stage stratified sampling as the survey objects. A cross-sectional survey was conducted on an online platform, using the general information questionnaire and Chinese version of methodist health care system nurse caring instrument revised by the research group. The latter instrument consists of 12 dimensions. namely care coordination, competence, teaching/learning, emotional support, respect for individuality, physical comfort, availability, helping/trusting relationship, patient/family engagement, physical environment, spiritual environment and outcomes. Descriptive analysis was performed on the data collected by the questionnaires, and independent sample t-test and one-way ANOVA were used to analyze the influencing factors of patient satisfaction. Results:A total of 107 hospitals were selected for questionnaire survey, including 86 tertiary hospitals and 21 secondary hospitals, and 29 108 valid questionnaires were recovered. The patient satisfaction with nursing humanistic care scored (5.40±0.86); the top three dimensions were competence (5.50±0.89), emotional support (5.47±0.88) and helping/trusting relationship (5.46±0.86); the lowest scoring dimensions were teaching/learning (5.38±1.01), spiritual environment (5.36±1.04) and patient/family engagement (5.11±1.28). Differences with gender, age, marital status, child status, educational level, occupation, place of residence, economic region, per capita monthly income of the family, type of medical insurance, medical department visited and surgery or not presented significant differences on the patient satisfaction with nursing humanistic care scores ( P<0.05). Conclusions:The satisfaction of patients with hospital′s nursing humanistic care in China was at the middle to upper level. In the future, health education for patients should be strengthened, and a mode of family-engaged nursing humanistic care should be constructed in line with the Chinese cultural background. In the process of nursing services, the particularity of patient groups should be considered to better meet their needs.

ObjectiveTo investigate the effect and mechanism of Nongsuo Dangguiwan in improving ovarian oxidative stress in rats with ovarian dysfunction. MethodThirty-six adult female SD rats were randomly divided into normal group, model group, positive drug group (Femoston, 0.3 mg·kg-1), and high-, medium-, and low-dose groups of concentrated Nongsuo Dangguiwan (2.08, 4.16, 8.32 g·kg-1), with six rats in each group. Rats, except for those in the normal group, were injected with 80 mg·kg-1 vinyl cyclohexene dioxide (VCD) per day for 14 consecutive days to induce ovarian dysfunction. From the 15th day, rats were treated with corresponding drugs by gavage, while those in the model group received 2 mL·kg-1 saline, once daily for 28 consecutive days. The ovarian index, levels of related hormones including estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and anti-mullerian hormone (AMH) in serum, as well as superoxide dismutase (SOD) activity and glutathione (GSH) content in serum were measured by enzyme-linked immunosorbent assay (ELISA). The malondialdehyde (MDA) content in serum was detected by the thiobarbituric acid (TAB) method. Ovarian morphology was observed by hematoxylin-eosin (HE) staining. The expression of nuclear factor E2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), SOD2, and SOD1 in ovarian tissues was detected by immunohistochemistry (IHC) and Western blot. ResultCompared with the normal group, the model group showed a significant reduction in growing follicles in the ovary, loose arrangement of granulosa cells in the follicle, decreased body weight, ovarian index, and serum AMH and E2 levels, increased LH and FSH levels (P<0.01), reduced levels of SOD and GSH in serum (P<0.01), and increased MDA level (P<0.01). Compared with the model group, the groups with drug intervention showed increased ovarian index (P<0.05, P<0.01), increased serum E2 level (P<0.05, P<0.01), decreased FSH, AMH, and LH levels (P<0.05, P<0.01), increased number of growing follicles in the ovary, potentiated SOD activity in serum, increased GSH content, decreased MDA content (P<0.05, P<0.01), and up-regulated expression levels of Nrf2, HO-1, SOD2, and SOD1 proteins in ovarian tissues (P<0.05, P<0.01). ConclusionNongsuo Dangguiwan can regulate serum hormone levels, increase the expression of Nrf2, HO-1, SOD2, and SOD1 in ovarian tissues, and improve ovarian antioxidant capacity to resist oxidative stress injury, thereby improving ovarian reserve function.

ObjectiveTo explore the mechanism of Jianpi Yishen Huazhuo prescription in the improvement of ovarian function in polycystic ovary syndrome (PCOS). MethodSeventy female SD rats in SPF grade were randomly divided into 6 groups, 15 in the blank group and 15 in the model group, 10 in the metformin group (0.1 g·kg-1·d-1), and 10 in the low (1.275 g·kg-1·d-1), medium (2.55 g·kg-1·d-1), and high-dose (5.10 g·kg-1·d-1) Jianpi Yishen Huazhuo prescription groups. The blank group was given normal saline (10 mL·kg-1·d-1) by gavage and ordinary feed, and the other groups were given letrozole (1 mg·kg-1·d-1) by gavage combined with high-fat feed for 21 days to induce the model of PCOS. After modeling, the blank group and model group were given equal volume normal saline by gavage, and each drug group was given the corresponding dose of the drug by gavage for 30 days. The changes in body mass and fasting blood glucose (FPG) of rats before and after modeling were compared. Hematoxylin eosin (HE) staining was used to observe the morphological change in the ovaries of rats in each group. The serum levels of follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T), anti-Mullerian hormone (AMH), and estradiol (E2) were measured by enzyme-linked immunosorbent assay (ELISA), and the LH/FSH ratio was calculated. Immunohistochemical staining (IHC) and Western blot were used to detect the protein expression levels of nucleoside binding oligomerization domain protein like receptor 3 (NALP3), apoptosis-associated speck-like protein (ASC), cysteine protease-1 (Caspase-1), nuclear transcription factor-κB (NF-κB), interleukin-1β (IL-1β), interleukin-18 (IL-18), and interleukin-6 (IL-6) in the rat ovaries. ResultAs compared with the blank group, large follicles with polycystic expansion were found in the ovaries of the model group, no dominant follicles were found, the granular layer of follicles decreased and arranged loosely, and the number of corpus luteum decreased significantly. Serum T, LH, AMH and LH/FSH increased in the model group (P<0.05, P<0.01), while FSH and E2 decreased (P<0.05, P<0.01). The relative protein expression levels of NALP3, ASC, Caspase-1, NF-κB, IL-1β, IL-18, and IL-6 increased (P<0.05, P<0.01) in the ovaries of the model group. Compared with the model group, the low, medium, and high-dose Jianpi Yishen Huazhuo prescription groups and the metformin group showed growing follicles and corpus luteum at all levels, the number of cystic expanding follicles decreased, the thickness of follicular granular layer increased, the number of follicular fluid increased, mature follicles were visible, and the local morphology of oocytes was complete. Serum T, LH, AMH, and LH/FSH in these groups decreased (P<0.05, P<0.01), while E2 and FSH increased (P<0.05). The relative protein expressions of NALP3, ASC, Caspase-1, NF-κB, IL-1β, IL-18, and IL-6 in the ovaries of these groups decreased (P<0.05, P<0.01). There was no significant difference among the treatment groups. ConclusionBy inhibiting the activation of NLRP3 inflammasome, Jianpi Yishen Huazhuo prescription reduces the release of NALP3, ASC, Caspase-1, NF-κB, IL-18, IL-1β, and IL-6 inflammatory factors in ovarian tissues, regulates endocrine level, and effectively reduces PCOS inflammatory statu, so as to play a role in improving ovarian function.
