Objective: To construct the item framework and weight coefficients of Toddler Anal Function Assessment Scale for children aged 1 to 3 years, so as to provide a tool for evaluating anal function in this age group. Methods: The items of the anal function assessment scale for infants and toddlers were developed through theoretical deduction, literature review, and interviews. After three rounds of screening and discussion within the research working group, a preliminary assessment framework comprising 4 dimensions and 12 items was established. Two rounds of Delphi expert consultation were conducted with experts specializing in pediatrics, traditional Chinese medicine proctology, and perianal imaging for infants and toddlers. The quality of the expert consultation was evaluated using the response rate, authority coefficient, and degree of agreement among experts. Items were screened based on importance scores, full-score ratio, accuracy scores, and coefficient of variation. The weights of the indicators were determined using the analytic hierarchy process. Results: A total of 18 experts participated in the consultation, including 9 males and 9 females. The mean age of the experts was (51.17±9.36) years and the mean years of practice was (26.56±9.95) years. Eleven held a master's degree or higher, and 17 held senior or above professional titles. The response and return rates for two rounds of Delphi consultation were 100%. The authority coefficients were 0.810 and 0.825, respectively. Kendall's coefficients were 0.096 and 0.131 (both P<0.05); and the coefficients of variation ranged from 0.14 to 0.28 and 0.12 to 0.32, respectively. The scale includes 4 dimensions and 10 items. The dimensions are the assessment of fecal control capability, impact on daily life, defecation status, and interventions and perianal appearance, with weight coefficients of 0.520 7, 0.222 4, 0.144 3, and 0.112 6, respectively. Among the items, those with higher weights are soiling, fecal control capability, control over solid stool, control over watery or loose stool, and activity restriction, with weights of 0.101 2, 0.064 7, 0.058 8, 0.046 4, and 0.035 4, respectively. Conclusion The constructed scale for assessing anal function in toddlers, comprising 4 dimensions and 10 items, can be applied to clinical evaluation or efficacy assessment of anal function in toddlers aged 1 to 3 years.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

Objective: To evaluate the effect of traditional Chinese medicine (TCM) on anthracycline-induced car-diotoxicity (AIC) in animal models. Methods: Separate systematic searches for preclinical studies were performed in the PubMed, EMBASE, Web of Science, Chinese National Knowledge Infrastructure, Chinese Biomedical Database, Chinese Sci-entific Journal Database, and Wanfang Data from inception to August 2019. The primary outcomes were echocardiography, serum assays for myocardial enzymograms, histological assessments, and electro-cardiograms. The secondary outcomes mainly included body weight and safety evaluations. The protocol is registered on PROSPERO (CRD42019145819). RevMan (V.5.3) was used for meta-analysis. Results: We identified 10 studies from 9 international scientific publications describing the efficacy of TCM on AIC animal models. All the included studies reported that, compared with animal model without any intervention, TCM significantly improved ventricular function, cardiac biomarkers, electrocardio-graph results, and cardiac fibrosis. Improved survival rates and body mass indices were also observed with TCM. We further pooled the available data from four studies (63 animals) for the meta-analysis and the results showed that, compared with models without any intervention, TCM significantly increased the ejection fraction by 14.13％ (95％ CI, 9.96-18.29) and fraction shortening by 8.66％ (95％ CI, 6.05-11.26). Creatine kinase-MB (SMD = -2.49, 95％ CI: -3.12 to -1.85) and lactate dehydrogenase (SMD =-2.78, 95％ CI:-3.45 to-2.12) were also significantly decreased by TCM. Conclusions: TCM is effective in improving AIC in animal models and has tremendous potential to be translated to treat AIC in clinical practice. Additionally, the systematic review and meta-analysis of an-imal experiments may be valuable in enhancing and guiding animal experiments and promoting the transformation of the results.

Objective To investigate the impact of paced QRS duration (pQRSd) on heart function in patients with right ventricular apical pacing. Methods Seventy-six patients with Ⅲ° atrioventricular block received pacemaker treatment were enrolled and randomized into group A (pQRSd < 190 ms, n = 52) and group B(pQRSd≥ 190 ms, n = 24). The concentration of brain natriuretic peptide (BNP),parameters of left atrial diameter (LAD), left ventricular ejection fracetion (LVEF), left ventricular end diastolic diameter (LVEDD), left ventricular end systolic dimension (LVEDD) were measured before operation, at 12 months and 24 months after implanting, respectively. The parameters of echocardiography assay, the concentration of BNP and the incidence of heart failure event after implantation were compared between two groups. Results At 12 months after implanting, LVEF of the patients in the group B decreased significantly compared with that of group A (P < 0.05). However, the echocardiography paramenters and the concentration of BNP were not significantly different between the two groups (P > 0.05). At 24 months after implanting, LAD、LVEDD、LVESD of group B increased significantly compared with those of group A [LAD,( 44.5 ± 6.2) mm vs (41.6 ± 5.1) mm, LVEDD, (52.7 ± 9.3) mm vs (48.2 ± 7.5) mm, LVESD, (37.5 ± 5.6) mm vs (33.8 ± 4.9)mm, each P < 0.05, respectively]. The concentration of BNP of group B increased significantly [(408.2 ± 102.1)ng / L vs (243.7 ± 92.8)ng / L, P < 0.001], and LVEF of the patients in group B decreased significantly compared with those of group A [(46.3 ± 6.8)% vs (51.6 ± 5.2)%, P < 0.001], respectively. No significant difference in the incidence of heart failure event (41.7% vs 26.9%, P > 0.05)between two groups during 24-month follow-up. Conclusion The prolonged paced QRS duration has a detrimental effect on long-term cardiac function during RVA pacing in patients with Ⅲ°atrioventricular block.

Objective: This study was to develop an experimental rat model of subcutaneous fistula induced by bacteria infection and treat it with thread-dragging therapy. Methods: A spring-gauze was surgically implanted into 24 male Sprague-Dawley rats' dorsal muscles, respectively, then mixed Staphylococcus aureus and Escherichia coli were injected into the spring-gauze. After 45 d, all the spring-gauzes were removed from the rats under anesthesia. X-ray and ultrasound were performed to assess the fistula tract. Each rat was examined by a fistula probe and four rats were randomly selected for histological assessment. The residual rats were randomly divided into two groups. Group A was treated with thread-dragging therapy, and group B was treated with fistulotomy. The healing time and body weight of the two groups were compared. Results: On the 45th day of the spring-gauze implantation, imaging assessment proved a tract with two openings in all rats and histological results proved that lumen and surrounding granulation tissue with epithelium were similar to the features of fistula in human beings. The mean healing time of rats in group A was shorter than that of the rats in group B (P<0.01). The body weight of rats in group A was heavier than that of the rats in group B on the 7th and 14th day after surgery, respectively (P<0.05). Conclusion: A rat model of subcutaneous fistula induced by mixed Staphylococcus aureus and Escherichia coli infection was successfully established. Traditional Chinese medicine thread-dragging therapy is less invasive and safer than fistulotomy.
