Objective To compare the effectiveness of femoral neck system(FNS)and inverted triangle cannulated screws(ITCS)in the treatment of femoral neck fractures in young adults.Methods A retrospective study was conducted on 106 young and middle-aged patients who had been surgically treated for femoral neck fracture at our hospital from December 2020 to June 2022.The patients were assigned to FNS group(57 cases)or ITCS group(49 cases)according to the different internal fixations.The operation time,intraoperative fluoroscopy frequency,intraoperative blood loss,extra assisted reduction procedures(Kirschner wire prying reduction or open reduction),hospital stays,healing time,complications,postoperative recovery,and follow-up duration were compared between the two groups.Results The operation time,fluoroscopy frequency,and healing time in the FNS group were less than those in the ITCS group(P<0.001).The shortening degree and length of femoral neck in moderate and severe patients of the FNS group were lower than those of the ITCS group(P<0.001).The Harris score of the FNS group was higher than that of the ITCS group 12 months after surgery(P<0.001).There was no significant difference in intraoperative blood loss,reduction assistance,Garden index,or hospital stays between the two groups(P>0.05).Conclusion FNS is a better choice for internal fixation in patients with femoral neck fractures than ITCS,with faster recovery and less postoperative complications.

OBJECTIVE To systematically evaluate the efficacy and safety of different chemotherapy combination regimens for first-line treatment of metastatic colorectal cancer （mCRC）. METHODS PubMed， Cochrane Library， Embase and Web of Science were electronically searched to collect randomized controlled clinical trial （RCT） on first-line treatment for mCRC from January 1， 2000 to February 16， 2025. Two reviewers independently screened literature， extracted data and assessed the risk of bias of the included studies. Network meta-analysis was performed by using R4.4.3 and Stata 17.0 software. RESULTS A total of 28 RCTs， involving 16 intervention measures， were included. In terms of prolonging progression-free survival （PFS） and overall survival （OS）， FOLFOX （5-fluorouracil+oxaliplatin+calcium folinate regimen）+cetuximab had the highest probability of ranking first. In terms of improving objective response rate （ORR）， FOLFOXIRI （5-fluorouracil+oxaliplatin+irinotecan+calcium folinate regimen）+ bevacizumab and FOLFOX+bevacizumab+nivolumab had the highest probability of ranking first； in terms of the incidence of grade 3 or higher adverse reactions， FOLFOXIRI+panitumumab had the highest probability of ranking first； in subgroup analysis of KRAS wild-type patients， FOLFIRI （5-fluorouracil+irinotecan+calcium folinate regimen）+panitumumab and FOLFIRI+bevacizumab had the highest probability of ranking first in terms of prolonging PFS and OS， respectively； in terms of ORR， FOLFOXIRI+ cetuximab had the highest probability of ranking first. CONCLUSIONS In first-line treatment for mCRC， FOLFOX combined with targeted therapy has advantages in terms of efficacy and safety. However， individualized treatment strategies should be formulated based on the KRAS gene status and tumor location of patients.

Objective:To construct a sensitive quality index system for ophthalmic day surgery nursing.Methods:Based on the "structure-process-outcome" three-dimensional quality model, a preliminary screening of sensitive quality indicators for ophthalmic day surgery nursing was conducted through the literature review, survey of current situation, and group meeting. Purposive sampling was used to select 29 members of the expert pool of the Ophthalmology Nursing Committee of Chinese Nursing Association for two rounds of Delphi expert consultation from August to September 2023.Results:In the two rounds of expert consultation, 29 and 23 questionnaires were distributed respectively, and 23 and 21 valid questionnaires were recovered respectively, with effective recovery rates of 79.31% and 91.30% respectively. The expert authority coefficients were both 0.88. The Kendall's coefficient of concordance for the importance of indicators was 0.111 and 0.127, respectively (both P<0.01). The final formed sensitive quality index system for ophthalmic day surgery nursing included three primary indicators, nine secondary indicators, and 40 tertiary indicators. Conclusions:The sensitive quality index system for ophthalmic day surgery nursing constructed in this study is scientific, reliable, and practical, which can provide a reference for evaluating the quality of nursing in ophthalmic day surgery.

Objective To understand the residual levels of eugenol in aquatic products sold in 4 cities in Hubei Province and timely discover potential food safety hazards, and to provide a scientific basis for supervision of eugenol in aquaculture and transportation of aquatic products. Methods From 2021 to 2023, 124 samples of aquatic products were randomly collected from supermarkets and farmers’ markets in Yichang, Xiantao, Jingmen, and Ezhou cities in Hubei Province. The ultra-high performance liquid chromatography-mass spectrometry was used to detect the residues of eugenol. Results Eugenol was detected in 51 out of 124 samples, with a detection rate of 41.13%，and a concentration range of N.D. - 2601μg/kg. Among them, 19 out of 40 samples were detected in 2021, with a detection rate of 47.50%; 12 out of 40 samples were detected in 2022, with a detection rate of 30.00%; and 20 out of 44 samples were detected in 2023, with a detection rate of 45.45%. There was no statistically significant difference in the detection rates in different years (P>0.05). The detection rates of eugenol in aquatic products sold in Yichang City, Xiantao City, Jingmen City, and Ezhou City were 22.58%, 35.48%, 41.94%, and 64.52%, respectively, and the differences were statistically significant (P<0.05). The detection rates of samples in supermarkets and farmers' markets were 35.56% and 44.30%, respectively, and the difference was not statistically significant (P>0.05). The detection rate of eugenol in bighead carp was the highest at 66.67%, followed by grass carp with a detection rate of 61.22%, which was significantly higher than other fish (P<0.05). Conclusion At present, the widespread use and arbitrary addition of eugenol should be paid attention to by relevant departments.

Objective:To explore the effects of anhedonia, childhood abuse, and depression on suicidal ideation, and the mediating role of anhedonia in adolescents.Methods:A total of 7 431 middle school students were invited to participate in the study. Suicidal ideation, depression, childhood abuse, and anhedonia were assessed by the Positive and Negative Suicide Ideation Scale (PANSI), Self-Rating Depression Scale (SDS), Childhood Trauma Questionnaire (CTQ) and Temporal Experience of Pleasure Scale (TEPS); according to the score of suicidal ideation, a total score of 36 was used as the cut-off score, all students were divided into the group with suicidal ideation ( n=1 265) and the group without suicidal ideation ( n=6 166). Difference test was performed using independent sample t-test and χ 2 test; Correlation analysis was performed by Pearson correlation; The process macro program compiled by Hayes was used to conduct the regulated mediation model analysis; The mediation effect values and 95%bootstrap confidence intervals of depressive symptoms between childhood maltreatment and suicidal ideation were analyzed by the bootstrap method; Simple slope analysis was utilized to examine the interaction effects for depression and anhedonia. Results:The detection rate of adolescent suicidal ideation was 17.02% (1 265/7 431);Childhood abuse significantly positively predicted depression ( β=0.56, P<0.001); depression significantly positively predicted suicidal ideation ( β=0.59, P<0.001); depression and anhedonia interaction significantly predicted suicidal ideation ( β=-0.05, P<0.001); simple slope analysis indicates that low anhedonia depression predicted suicidal ideation ( β=0.51, P<0.001) than the high anhedonia group ( β=0.47, P<0.001). Conclusion:Depression partially mediates the effects of childhood abuse on suicidal ideation, and anhedonia modulates the effects of childhood abuse on suicidal ideation. As the level of anhedonia gradually increases, the predictive effect of depression on suicidal ideation gradually decreases.
