OBJECTIVE: To compare the impact of different peroneus longus tendon (PLT) stump management techniques on ankle function following arthroscopic anterior cruciate ligament (ACL) reconstruction with autologous PLT grafts. METHODS: A retrospective analysis was conducted on 60 patients with ACL rupture who met the inclusion criteria between August 2020 and July 2024. All patients underwent arthroscopic ACL reconstruction using the autologous PLT grafts. Patients were assigned to group A [PLT stump sutured to peroneus brevis tendon (PBT), n=30] or group B (no stump intervention, n=30). The two groups showed no significant difference ( P>0.05) in baseline data, including gender, age, body mass index, injury mechanism, affected side, preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score, ankle muscle strength, ankle range of motion, and arch-related angles. Postoperative outcomes were assessed using the AOFAS score, ankle muscle strength (eversion and first-ray plantar flexion), arch-related angles (medial/lateral longitudinal and anterior/posterior arch), ankle range of motion (eversion, inversion, dorsiflexion, plantarflexion), and limb symmetry index (LSI). Change values in muscle strength, arch-related angles, and range of motion from preoperative to 12 months postoperatively were calculated for intergroup comparison. RESULTS: Groups A and B had comparable PLT graft lengths and diameters ( P>0.05). All patients were followed up 13-16 months (mean, 14.5 months). Postoperative complications included 1 case of incision infection, 1 case of deep vein thrombosis, and 1 case of knee stiffness in group A, 1 case of knee stiffness in group B. There was no significant difference in the overall complication incidences between groups ( P>0.05). No significant difference was found in the AOFAS scores between different time points and between groups ( P>0.05). At 12 months after operation, neither group showed significant changes from preoperative baseline in ankle strength, range of motion, or arch-related angles, and there was no significant difference in these change values between groups ( P>0.05). There was no significant difference in LSI between the two groups at 6 or 12 months postoperatively ( P>0.05). CONCLUSION Both suturing and leaving the PLT stump untreated during arthroscopic ACL reconstruction provided comparable ankle outcomes and well-preserved foot and ankle function.

Objective:To explore the hypothesis of "pathogen storage pool" by analyzing the local microbial community of adenoids. Methods:Under the guidance of a 70° nasal endoscope, sterile swabs were used to collect secretions from the adenoid crypts of the subjects. The samples were sent to the laboratory for DNA extraction and standard bacterial 16S full-length sequencing analysis. Results:At the species level, the top three microbial communities in adenoid crypts were Bacillus subtilis（18.78%）, Fusobacterium pyogenes（11.42%）, and Streptococcus pneumoniae（9.38%）. Conclusion:The local microbial community of adenoids exhibits a high degree of diversity, including microbial communities from the oral cavity and gastrointestinal tract. Our research results support the hypothesis that adenoids act as a " pathogen reservoir".

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 explore the mediating effect of self-management efficacy between social support and self-management behavior in cancer patients treated with proton-heavy ions.Methods:From April 2020 to April 2021, convenience sampling was used to select 674 cancer patients in Shanghai Proton and Heavy Ion Center as the research subject. The patients were investigated with the General Information Questionnaire, Chronic Disease Self-Management Study Measures (CDSMS) , Chinese-version Strategies Used by People to Promote Health (C-SUPPH) , and Medical Outcome Study Social Support Survey (MOS-SSS) . Statistical analysis was performed using SPSS 24.0 and AMOS 24.0 software. Pearson correlation was used to calculate the correlation between variables, and a structural equation model was constructed to test the relationship between variables. A total of 674 questionnaires were distributed, 610 valid questionnaires were recovered, and the valid recovery rate was 90.5% (610/674) .Results:The total scores of self-management behavior, self-management efficacy, and social support in 610 cancer patients treated with proton heavy ions were (18.38±7.64) , (94.30±22.72) and (73.97±13.94) , respectively. Pearson correlation analysis showed that except for the dimension of life support with dimension of exercise, all the other dimension scores and the total score of patients' social support were positively correlated with all the dimension scores and the total score of self-management behaviors ( P<0.05) ; the dimension scores and the total score of patients' social support were positively correlated with the dimension scores and the total score of self-management efficacy ( P<0.05) ; the dimension scores and the total score of patients' self-management efficacy were positively correlated with the dimension scores and the total score of self-management behavior ( P<0.05) . Self-management efficacy had a partial mediating effect between social support and medical staff communication behavior, with an effect value of 23.4% ( P<0.05) . Conclusions:Cancer patients treated with proton-heavy ions have poor levels of self-management behavior. Nurses can improve the patients' self-efficacy and enhance the impact of social support on the patients' self-management behavior, so as to promote the precise realization and timely completion of proton heavy ion therapy.

Objective:To investigate the related factors affecting intraoperative blood loss in patients with spinal tumors undergoing preoperative selective arterial embolization.Methods:The clinical data of 90 patients with spinal tumors who underwent preoperative selective arterial embolization in the Affiliated Hospital of Jining Medical College and the Second Affiliated Hospital of Shanxi Medical University from January 2017 to December 2020 were retrospectively analyzed. The influencing factors of intraoperative bleeding were analyzed by using multiple linear regression.Results:There were statistically significant differences in intraoperative blood loss of spinal tumor patients undergoing preoperative selective arterial embolization with different blood supply abundance and the number of tumors involving vertebral body (all P < 0.05). There were no significant differences in age, gender, body mass index, interval after embolization, operation time, pathological type, tumor site, embolization degree, the number of embolized vessels, preoperative Frankel grade among different groups (all P > 0.05). Multiple linear regression analysis showed that the number of tumors involving vertebral body and tumor blood supply abundance were factors affecting intraoperative blood loss, and vertebra number and tumor blood supply were positively correlated with intraoperative blood loss (all P < 0.05). Conclusion:For patients with spinal tumors undergoing preoperative selective arterial embolization, the number of tumors involving vertebral body and the abundance of the tumor blood supply are factors affecting the amount of intraoperative bleeding.

Objective:To investigate the effects of chest pain center construction in basic-level hospitals on treatment time and short-term prognosis in patients with acute ST-elevation myocardial infarction.Methods:A total of 162 patients with acute ST-elevation myocardial infarction who received percutaneous coronary intervention (PCI) in The First People's Hospital of Jiande between November 2014 and November 2018 were included in this study. Among them, 66 patients who received treatment in The First People's Hospital of Jiande between November 2014 and October 2016 were included in the control group. The remaining 96 patients who received treatment between November 2016 and November 2018 were included in the study group. The underlying diseases, PCI success rate, first medical contact-to-balloon time, door-to-balloon time, in-hospital mortality, incidence of heart failure on the next day of PCI, length of hospital stay, hospital medical cost were retrospectively analyzed.Results:There were no significant differences in underlying disease composition ratio and PCI success rate between the two groups (both P > 0.05). There were significant differences in first medical contact-to-balloon time [(185.2 ± 53.7) minutes vs. (108.6 ± 46.4) minutes, t = 6.128], door-to-balloon time [(121.5 ± 23.2) minutes vs. (68.7 ± 14.3) minutes, t = 7.341], length of hospital stay [(10.3 ± 3.5) days vs. (7.2 ± 2.8) days, t = 5.128], hospital medical cost [(43 582.0 ± 7 186.5) yuan vs. (35 479.0 ± 4 213.1) yuan, t = 8.361], in-hospital mortality [6.1% vs. 3.1%, χ2 = 4.784], the incidence of heart failure on the next day of PCI [13.6% vs. 4.2%, χ2 = 8.253] between the control and study groups (all P < 0.05). Conclusion:Establishment of a standardized chest pain center construction in basic-level hospital can greatly shorten the first medical contact-to-balloon time, door-to-balloon time and length of hospital stay, improve the cardiac function and prognosis of patients with myocardial infarction, and reduce medical cost.

Objective:To compare the short-term clinical effect of arthroscopic and open reduction and internal fixation with Herbert screws in treatment of Mason type II radial head fractures.Methods:A retrospective case-control study was conducted to analyze the clinical data of 38 patients with unilateral radial head fractures (Mason type II) admitted to Shanghai Zhongye Hospital from January 2017 to December 2018, including 22 males and 16 females, aged from 20 to 65 years [(37.4±12.6)years]. Twenty patients were treated by arthroscopic reduction and internal fixation with Herbert screw (Group A), and eighteen by open reduction and internal fixation with Herbert screw (Group B). The operation time and fracture healing time were recorded. The visual analogue scale (VAS), elbow flexion and extension range, forearm rotation range and Mayo elbow function score were compared between the two groups before and at 1, 3, 6, and 12 months after operation. The results of Mayo elbow performance score (MEPS) and upper limb function assessment using the disabilites of the arm, shoulder, and hand (DASH) score were compared between the two groups. Complications including screw breakage or fracture displacement were also evaluated.Results:All patients were followed up for 12-14 months [(12.3±2.3)months]. There was no significant difference in operation time between the two groups ( P>0.05). The fracture healing time was (8.9±0.6)weeks in Group A and (8.7±0.6)weeks in Group B ( P>0.05). There was no significant difference in VAS between the two groups before operation ( P>0.05). The VAS was (4.8±0.5)points at 1 month after operation in Group A, lower than (6.0±0.7)points in Group B ( P<0.05). There was no significant difference in VAS between Group A and Group B at 3, 6, and 12 months after operation ( P>0.05). There was no significant difference in elbow flexion and extension range between the two groups before operation ( P>0.05). The elbow flexion and extension range in Group A was (110.4±3.8)° and (137.1±4.0)° at 1, 3 months after operation, which was significant greater than (90.6±4.7)° and (125.1±3.5)° in Group B ( P<0.05). There was no significant difference in elbow flexion and extension range between the two groups at 6 and 12 months after operation ( P>0.05). There was no significant difference in the range of forearm rotation between the two groups before operation ( P>0.05). The range of forearm rotation in Group A was (107.1±2.8)° and (138.1±2.9)° at 1, 3 months after operation, significantly greater than (95.5±3.9)°, (121.5±3.0)° in Group B ( P<0.05). There was no significant difference in forearm rotation range between the two groups at 6 and 12 months after surgery ( P>0.05). There was no significant difference in MEPS between the two groups before operation ( P>0.05). The MEPS in Group A was (50.4±3.8)points at 1 month after operation, higher than (40.6±4.7)points in Group B ( P<0.05). There was no significant difference in MEPS between the two groups at 3, 6, and 12 months after operation ( P>0.05). There was no significant difference in DASH score between the two groups before operation ( P>0.05). The DASH score was (57.1±2.8)points at 1 month after surgery in Group A, higher than (42.5±3.9)points in Group B ( P<0.05). The DASH score was not significantly different between the two groups at 3, 6, and 12 months after operation ( P>0.05). There was no screw loosening or fracture after operation, and one patient in each group had fracture displacement ( P>0.05). Conclusion:For Mason type II radial head fractures, arthroscopic Herbert screw fixation has the advantages of less trauma, less pain and faster functional recovery of the affected limb compared with open reduction and Herbert screw fixation.

Objective:To compare the curative efficacy in the treatment of humeral surgical neck fractures between open reduction and locking plating versus closed reduction and interlocking intramedullary nailing.Methods:From July 2018 to July 2020, 60 patients with humeral surgical neck fracture were treated at Department of Orthorpaedic Trauma, Jiangmen Wuyi Hospital of Traditional Chinese Medicine. They were 24 males and 36 females, aged from 40 to 70 years and injured at the left side in 35 cases and at the right side in 25 ones. Of them, 30 underwent open reduction and locking plating (open group) and the other 30 closed reduction and interlocking intramedullary nailing (closed group). The 2 groups were compared in terms of operation time, intraoperative blood loss, surgical incision length, fracture healing time, Neer shoulder function scoring 3 months after surgery, and postoperative complications.Results:There were no statistically significant differences between the open and closed groups in preoperative general data, showing they were comparable ( P>0.05). The length of surgical incision [(5.2±1.1) cm], operation time [(34.3±12.7) min], intraoperative blood loss [(52.5±7.3) mL] and fracture healing time [(9.2±1.5) weeks] in the closed group were significantly better than those in the open group [(11.1±2.5) cm, (69.4±21.4) min, (123.5±5.2) mL and (14.2±3.4) weeks)] ( P<0.05). The excellent and good rate by Neer shoulder function scoring at 3 months after operation in the closed group (93.3%, 28/30) was significantly higher than that in the open group (66.7%, 20/30) ( P<0.05). There were no postoperative complications in either group. Conclusion:In the treatment of humeral surgical neck fractures, the curative efficacy of closed reduction and interlocking intramedullary nailing is better than that of open reduction and locking plating.

Objective:To analyze the prevalence and associated factors of malnutrition among children under 6 years of age in Hunan province.Methods:This study was a cross-sectional study. A combination of multistage stratified cluster sampling and systematic sampling approach was used to recruit 10 442 children aged 0-71 months from 144 communities (villages) across 48 streets(towns) in 24 districts(counties) from Hunan province between August and November 2019. Data concerning the children and their mothers, caregivers, and family conditions was collected using unified questionnaire, with the lengths/heights and weights of the children being measured using unified instruments. The length/height for age, weight for age, weight for length/height, and body mass index for age Z scores were calculated and used to evaluate the prevalence of children′s stunting, underweight, and wasting. The chi-square test was used to compare the prevalence of malnutrition among children with different characteristics. The multivariate Logistic regression model was used to conduct multivariate analysis for childrens′ malnutrition.Results:The prevalence of protein-energy malnutrition (PEM) among children under 6 years of age was 6.8% (710/10 442), and the prevalence of stunting, underweight, and wasting were 3.1% (328/10 442), 2.7% (280/10 442), and 3.3% (343/10 442), respectively. Rural areas ( OR=1.60), older age of children (compared with children of 0-11 months, the OR for 12-23, 24-35, 36-47, 48-59, and 60-71 months were 1.42, 1.75, 1.55, 1.70, and 1.88, respectively), low birth weight ( OR=2.72), caregivers of minority ethnicity ( OR=1.95), and large family size ( OR=1.25) were risk factors for children′s PEM. Rural areas and low birth weight were risk factors for stunting in children ( OR=2.13 and 3.28). Rural areas, low birth weight, caregivers of minority ethnicity, and large family size were risk factors for underweight in children ( OR=2.57, 3.34, 1.86, and 1.32). Rural areas ( OR=1.43), older age of children (compared with children of 0-11 months, the OR for 24-35, 36-47, 48-59, and 60-71 months were 1.63, 1.80, 1.84 and 2.17, respectively), low birth weight ( OR=2.36), caregivers of minority ethnicity ( OR=2.88), and large family size ( OR=1.42) were risk factors for children′s wasting. Higher education level of caregivers was a common protective factor for PEM, stunting, and underweight ( OR=0.85, 0.76, and 0.82). Conclusions:The prevalence of stunting, underweight, and wasting among children under 6 years of age in Hunan province were all at a low level. Nevertheless, the urban-rural differences still existed, with these prevalence being affected by children age, birth weight, ethnicity of caregivers, education level, and family size.
