Geraniin, a polyphenol derived from the fruit peel of Nephelium lappaceum L., has been shown to possess anti-inflammatory and antioxidant properties in the cardiovascular system. The present study explored whether geraniin could protect against an isoproterenol (ISO)-induced cardiac hypertrophy model. Mice in the ISO group received an intraperitoneal injection of ISO (5 mg/kg) once daily for 9 days, and the administration group were injected with ISO after 5 days of treatment with geraniin or spironolactone. Potential therapeutic effects and related mechanisms analysed by anatomical coefficients, histopathology, blood biochemical indices, reverse transcription-PCR and immunoblotting. Geraniin decreased the cardiac pathologic remodeling and myocardial fibrosis induced by ISO, as evidenced by the modifications to anatomical coefficients, as well as the reduction in collagen I/III á1mRNA and protein expression and cross-sectional area in hypertrophic cardiac tissue. In addition, geraniin treatment reduced ISO-induced increase in the mRNA and protein expression levels of interleukin (IL)-6, IL-1β and tumor necrosis factor-α, whereas ISO-induced IL-10 showed the opposite behaviour in hypertrophic cardiac tissue.Further analysis showed that geraniin partially reversed the ISO-induced increase in malondialdehyde and nitric oxide, and the ISO-induced decrease in glutathione, superoxide dismutase and glutathione. Furthermore, it suppressed the ISO-induced cellular apoptosis of hypertrophic cardiac tissue, as evidenced by the decrease in Bcell lymphoma-2 (Bcl-2)-associated X/caspase-3/caspase-9 expression, increase in Bcl-2 expression, and decrease in TdT-mediated dUTP nick-end labeling-positive cells.These findings suggest that geraniin can attenuate ISO-induced cardiac hypertrophy by inhibiting inflammation, oxidative stress and cellular apoptosis.

Objective:
To evaluate the impact of comprehensive nursing based on the behavioral goal attainment model on the clinical intervention effect among elderly female patients with stress urinary incontinence (SUI), so as to provide a basis for optimizing the nursing strategies for patients with SUI and improving their quality of life.
Methods:
A total of 190 elderly female patients with SUI who were treated in the Department of Gynecology of the First Hospital of Jilin University from January 2023 to August 2024 were selected and randomly divided into the intervention group and the control group. The control group received routine nursing care, while the intervention group received comprehensive nursing based on the behavioral goal attainment model. The 1-hour pad test was used to assess urinary incontinence symptoms. The bio-electrical stimulation feedback instrument was employed to detect the electromyogram (EMG) values in the pre-resting stage and slow-muscle stage for evaluating pelvic floor function. The bladder function scale was utilized to evaluate bladder function. The Chinese version of urinary incontinence ego-efficacy rating scales and incontinence quality of life assessment scale (IQOL) were used to assess self-efficacy and quality of life. The data on intervention compliance and nursing satisfaction were collected by a questionnaire survey. The differences between the two groups before and after the intervention were compared using the analysis of variance for repeated-measures data to evaluate the intervention effect.
Results:
There were 95 cases in the control group and 95 cases in the intervention group, with median ages were 64.00 (interquartile range, 23.50) and 64.50 (interquartile range, 19.50) years, respectively. The proportion of patients with cesarean section as the last delivery method was 21.05% in the control group and 12.63% in the intervention group. The proportion of patients with moderate disease severity was 67.36% in the control group and 58.95% in the intervention group. There were no statistically significant differences in age, body mass index, number of pregnancies, number of deliveries, marital status, educational level, mode of last delivery and severity of the disease between the two groups of patients (all P>0.05). The analysis of variance of repeated-measures data showed that there were significant interactions between time and group for the urine leakage volume in the 1-hour pad test, the EMG values in the pre-resting stage, the EMG values in the slow-muscle stage, the scores of the bladder function, the self-efficacy scores, and the IQOL scores (all P<0.05). After 12 weeks of intervention, the EMG values in the slow-muscle stage, the scores of the bladder function, the self-efficacy scores, the IQOL scores in the intervention group were higher than those in the control group, while the urine leakage volume in the 1-hour pad test and the EMG values in the pre-resting stage in the intervention group were lower than those in the control group (all P<0.05). The good compliance rate of intervention and the satisfaction rate of nursing in the intervention group were higher than those in the control group (83.16% vs. 60.00%, 90.53% vs. 75.79%, both P<0.05).
Conclusion
Comprehensive nursing based on the behavioral goal attainment model can improve urinary incontinence symptoms, pelvic floor function, bladder function, self-efficacy, quality of life, and intervention compliance of elderly female patients with SUI.

OBJECTIVE:
To observe the effects of acupoint catgut embedding (ACE) on gut microbiota and fecal short-chain fatty acids (SCFAs) levels in patients with Parkinson's disease (PD) with constipation.
METHODS:
A total of 80 PD patients with constipation were randomly divided into an observation group and a control group, 40 cases in each group. Additionally, 40 healthy individuals were recruited as a healthy control group. The control group received conventional Western medical treatment for PD combined with polyethylene glycol (PEG), once daily for eight weeks. The observation group received additional ACE treatment at bilateral Tianshu (ST25), Zusanli (ST36), and Shangjuxu (ST37), once every two weeks for eight weeks. The healthy control group received no intervention. The spontaneous bowel movements (SBMs) per week and patient assessment of constipation quality of life (PAC-QOL) scores were assessed at baseline and after treatment in the two groups. Fecal samples were collected at the end of treatment for the observation and the control groups and at baseline for the healthy control group. Gut microbiota composition and diversity were analyzed using 16S rRNA method, and SCFA levels were measured using high-performance liquid chromatography (HPLC).
RESULTS:
Compared before treatment, the observation group showed a significant increase in SBMs (P<0.01), and PAC-QOL scores including physical discomfort, psychosocial discomfort, worry and concern, and total score were significantly reduced (P<0.01) after treatment; the control group also showed a reduction in PAC-QOL total score after treatment (P<0.01). After treatment, the observation group had significantly more SBMs (P<0.01), and lower PAC-QOL physical discomfort, psychosocial discomfort, worry and concern scores, and total score (P<0.01), and higher PAC-QOL satisfaction score (P<0.01) than the control group. Compared with the healthy control group, the control group showed decreased Chao1 and Ace indices (P<0.01). Compared with the healthy control group, the relative abundance of Prevotella and Roseburia was increased (P<0.05), while that of Enterobacter and Ruminococcus torques (six species in total) was decreased (P<0.05) in the control group. Compared with the control group, the observation group had increased relative abundance of Dialister, Parabacteroides, and Ruminococcus torques (P<0.05), and decreased relative abundance of Prevotella and Eubacterium ruminantium (P<0.05). Compared with the healthy control group, the control group had increased fecal SCFA levels (P<0.05); compared with the control group, the observation group had reduced fecal SCFA levels (P<0.05). Compared with the healthy control group, acetic acid, propionic acid, and butyric acid levels were elevated in the control group (P<0.05); compared with the control group, acetic acid, propionic acid, and butyric acid levels were decreased in the observation group (P<0.05).
CONCLUSION
ACE could increase spontaneous bowel movements and improve the quality of life in PD patients with constipation, which may be related to the regulation of gut microbiota composition and SCFA levels.

Objective:To explore the mechanism by which Pien Tze Huang improves liver Kupffer cell damage induced by lipopolysaccharide (LPS) by regulating the expression of miR-155.Methods:LPS induced liver Kupffer cells to establish a cell injury model to simulate septic liver injury. RT-qPCR was used to detect the expression of miR-155 in damaged cells, and RT-qPCR, Western Blot, ELISA and flow cytometry were used to evaluate the inflammatory response and apoptosis of damaged cells. Then we treated LPS-induced Kupffer cells with Pien Tze Huang at different concentrations (0 mg/L, 5 mg/L, 10 mg/L and 15 mg/L), and detected the expression of miR-155 in the cells, the inflammatory response of the cells and Apoptosis rate. MiR-155 was silenced in the cell injury model, and RT-qPCR, Western Blot, ELISA and flow cytometry were used to evaluate the effect of miR-155 on inflammatory response and apoptosis of model cells. Overexpression of miR-155 in damaged cells treated with Pien Tze Huang was used to detect changes in cellular inflammatory response and apoptosis. Data are expressed in the form of mean ± standard deviation, and each group of data is analyzed using t test or one-way analysis of variance.Results:In the LPS-induced liver Kupffer cell injury model, the expression of miR-155 was significantly increased ( P<0.05), the expression levels of pro-inflammatory factors IL-6 and TNF-α were significantly increased, and the anti-inflammatory factor IL-10 was significantly increased. was inhibited ( P<0.05), and the cell apoptosis rate was significantly increased ( P<0.05). After Pien Tze Huang treatment, the expression of miR-155 in damaged liver cells was inhibited ( P<0.05), the levels of cellular inflammatory factors IL-6 and TNF-α were inhibited, and the expression of anti-inflammatory factor IL-10 was promoted ( P<0.05). Inhibit cell apoptosis ( P<0.05). Silencing miR-155 reduced the inflammatory response and apoptosis rate of cells ( P<0.05). Overexpression of miR-155 can reverse the effect of Pien Tze Huang on liver cell injury ( P<0.05). Conclusions:In the model of LPS-induced liver Kupffer cell injury, Pien Tze Huang can inhibite the inflammatory response and apoptosis of cells by inhibiting the expression of miR-155.

OBJECTIVE To excavate the adverse drug event (ADE) signals of three third-generation tetracycline antibiotics (tigecycline, omadacycline, eravacycline) based on FDA adverse event reporting system (FAERS), and to provide reference for the safe use of them. METHODS The ADE reports of tigecycline, omadacycline and eravacycline from the first quarter of 2005 to the second quarter of 2023 were retrieved from FAERS database. The ADE signals of 3 kinds of drugs were mined by the method of reporting odds ratio method and the proportional reporting ratio method. RESULTS Totally 2 538 ADE reports with tigecycline, omadacycline and eravacycline as the primary suspected drugs were obtained, including 2 135 tigecycline ADE reports, 349 omadacycline ADE reports and 54 eravacycline ADE reports. A total of 131 ADE positive signals of tigecycline were mined, involving 19 system organ classes (SOCs), mainly concentrated in investigations, hepatobiliary system, blood and lymphatic system, and gastrointestinal system, etc; the preferred terminologies (PT) with intense signal were hypofibrinogenaemia and blood fibrinogen decreased. Fourteen ADE signals were not mentioned in the drug instruction, such as renal failure, acute kidney injury and hemorrhage. Totally 24 ADE positive signals of omadacycline were mined, involving 6 SOCs, mainly concentrated in the gastrointestinal system and various examinations; the PTs with intense signals were tooth discoloration, jet-like vomiting and loose feces, etc. ADE signals were not mentioned in the drug instructions, included lip swelling, gastroesophageal reflux disease, eosinophilia, skin discoloration, feces softening, and night sweats. Five ADE positive signals of eravacycline were mined, involving 4 SOCs, mainly concentrated in various examinations, gastrointestinal system, etc. The most intense ADE signals were blood fibrinogen decreased and hypofibrinogenaemia. CONCLUSIONS ADE of the gastrointestinal system are mostly identified in the three third-generation tetracycline antibiotics, especially pancreatitis caused by tigecycline and gastroesophageal reflux disease caused by oral administration of omadacycline. The liver function, renal function (for tigecycline) and coagulation function (for tigecycline, eravacycline) should be monitored biyiliang@hotmail.com regularly during medication, so as to prevent the occurrence of serious ADE.
