ObjectiveTo investigate the effect and mechanism of polysaccharide in water extract of Cyclocarya paliurus （CPWP） in inhibiting benign prostatic hyperplasia （BPH）. MethodsCPWP was obtained by heating reflux， aqueous extraction， alcohol precipitation， and freeze drying. The chemical composition and structural properties of CPWP were analyzed by high performance liquid chromatography with 1-pheny-3-methyl-5-pyrazolone pre-column derivatization and infrared spectroscopy. Male SD rats were randomly assigned into control， model， finasteride （ig 5 mg·kg^-1）， and low-， medium-， and high-dose （ig 50， 75， 100 mg·kg^-1） CPWP groups， with 8 rats in each group. The BPH model was established by subcutaneously injecting propionate testosterone in castrated rats. The rats in the drug intervention groups were administrated with corresponding drugs， and those in the control group were administrated with an equal volume of normal saline each day. After 30 consecutive days， the rats were sacrificed， and the prostate tissue was separated and weighed. The effects of drug interventions on the body weight， prostate wet weight， and prostate index of rats were examined. The prostate tissue was stained with hematoxylin-eosin （HE） for observation of pathological changes. Enzyme-linked immunosorbent assay was employed to measure the level of dihydrotestosterone （DHT）， and immunohistochemical staining was used to detect the expression of steroid 5 alpha-reductase 2 （SRD5A2） and Ki67 in the prostate tissue. ResultsCPWP was identified as a saccharide， with characteristic absorption peaks of saccharides. CPWP showed the total sugar content of 44.15% and molecular weight within the range of 5.5-78.8 kDa， being composed of mannose， rhamnose， galacturonic acid， glucose， galactose， xylose， and arabinose. Compared with the control group， the model group had significantly increased prostate wet weight and prostate index （P<0.01）， thick and tall prostate epithelial cells， increased internal wrinkles， papillary expansion into the cavity， an elevation in DHT level in the serum， and up-regulated expression of SRD5A2 and Ki67 in the prostate tissue （P<0.05， P<0.01）. Compared with the model group， both the finasteride and CPWP groups showed decreases in prostate wet weight and prostate index （P<0.05， P<0.01）， thinned prostate epithelial cells， with only a small portion of internal wrinkles and papillary expansion into the cavity， shortened papillary protrusions， lowered DHT level in the serum， and down-regulated expression of SRD5A2 and Ki67 in the prostate tissue （P<0.01）. Moreover， CPWP exerted effects in a dose-dependent manner. ConclusionCPWP inhibits BPH by regulating the expression of SRD5A2.

Objective To explore the effectiveness of MACE rehabilitation system based on international classification of functioning,disability and health for children and youth(ICF-CY)in improving the function of children with cerebral palsy,and to provide a more targeted comprehensive plan for rehabilitation of children with cerebral palsy.Methods Sixty-six children with cerebral palsy admitted to the Second Affiliated Hospital of Wenzhou Medical University from October 2022 to December 2023 were selected as the research objects and randomly divided into experimental group and control group,with 33 cases in each group.The experimental group received comprehensive rehabilitation intervention based on the MACE rehabilitation system of ICF-CY,and control group received traditional rehabilitation treatment.Modified Ashworth scale score,knee joint range of motion,functional independence measure for children(WeeFIM)score,gross motor function measure(GMFM)and fine motor function measure(FMFM)score of two groups of children after intervention were evaluated and compared.Results After intervention,the modified Ashworth scale scores of two groups of children were significantly lower than those before intervention in this group,the range of motion of knee joint was significantly better than that before intervention in this group,and the WeeFIM score,GMFM score and FMFM score were significantly higher than those before intervention in this group(P＜0.05).The modified Ashworth scale score of children in experimental group was significantly lower than that of children in control group,the range of motion of knee joint was significantly better than that of children in control group,and the WeeFIM score,GMFM score and FMFM score were all significantly higher than those of children in control group(P＜0.05).Conclusion The MACE rehabilitation system based on ICF-CY can effectively improve the muscle tone and joint range of motion of children with cerebral palsy,and enhance functional independence and motor function.

Objective:To analyze the current status, hotspots, and trends of community integration (CI) at home and abroad, providing directions for subsequent research.Methods:The China National Knowledge Infrastructure and the Web of Science Core Collection data were used, and CiteSpace software was employed to analyze the publication, countries, disciplines, and keywords of CI.Results:A total of 932 Chinese and 2 319 English hits were included. The publication of CI had shown an increasing trend both domestically and internationally. Sociology and rehabilitation were the main disciplines in CI domestically and internationally, respectively. Domestically, CI research primarily focused on the community integration of migrant workers, floating populations, and accompanying family members. Internationally, the emphasis was on the integration of individuals with disabilities and other special groups. Future research directions in China were likely to focus on group work, the elderly, and relocated populations. Internationally, CI research would continue to concentrate on CI experiences and intervention methods for individuals with disabilities and special populations.Conclusion:CI is increasingly gaining attention both domestically and internationally. However, domestic research remains insufficient and needs to be expanded through more empirical studies in various vertical subfields. Future domestic scholars should continue to focus on CI of the elderly and engage in interdisciplinary research.

【Objective】 To explore the effect of metaphors based on children′s games on the negative emotion and behavior of children during the recovery period of traumatic brain injury, in order to provide reference for making intervention strategy for these children. 【Methods】 From May 2021 to October 2022, a total of 60 children aged 6-12 years who underwent rehabilitation in the rehabilitation center of the Second Affiliated Hospital of Wenzhou Medical University were selected into this study, and were randomly divided into experimental group and control group, with 30 cases in each group.The control group was given routine nursing, while the experimental group was given metaphorical intervention based on children′s games.The scores of social living ability, abnormal behavior detection rate, depression score, anxiety score and cognitive function were compared between the two groups. 【Results】 The scale score of the two groups was not significantly different before intervention(P>0.05).After intervention, the infant-junior high school students′ social living ability score, Mini-Mental State Examination and the Loewenstein Occupational Therapy Cognitive Assessment score in the experimental group were higher than those in the control group (t=3.175, 5.265, 7.835, P<0.001).The scores of Child Behavior Checklist (CBCL), the children′s depression inventory and the screen for child anxiety related emotional disorders in the experimental group were lower than those in the control group (Z=7.823, t=6.398, 6.248, P<0.001). 【Conclusions】 Metaphorical intervention based on children′s games can reduce the negative emotions of anxiety and depression in children with traumatic brain injury, improve their social life ability, reduce the CBCL score, and improve the cognitive function.

Objective:To evaluate the long-term outcomes and prognostic factors of locally advanced gastric cancer with serosa-invasion.Methods:This study is a retrospective cohort study. The clinical and pathological data of 495 patients with locally advanced gastric cancer with serosa-invasion who underwent laparoscopic radical gastrectomy in Department of General Surgery, the First Hospital Affiliated to Army Medical University from October 2012 to October 2018 was analyzed retrospectively. There were 356 males and 139 females with an age ( M(IQR)) of 59 (16) years (range: 18 to 75 years). Observation indicators included postoperative results and long-term prognosis. The survival curve was drawn by the Kaplan-Meier method. Univariate and multivariate prognostic analysis was performed using the Cox proportional hazards model. Results:Among the 495 patients, a total of 57 patients (11.5%) were lost to follow-up, with a follow-up time of 89 (40) months (range: 23 to 134 months). The 5-year disease-free survival rate (DFS) and the 5-year overall survival rate (OS) were 56.0% and 58.2%, respectively. The 5-year DFS for patients with stage ⅡB, ⅢA, ⅢB, ⅢC were 71.2%, 60.5%, 51.6%, 33.3%, respectively. The 5-year OS for patients with stage ⅡB, ⅢA, ⅢB, ⅢC were 71.2%, 62.2%, 54.1%, 39.3%, respectively. Multivariate analysis showed that age >65 years (DFS: HR=1.402, 95% CI: 1.022 to 1.922, P=0.036; OS: HR=1.461, 95% CI: 1.057 to 2.019, P=0.022), lymph node dissection number less than 25 (DFS: HR=1.348, 95% CI: 1.019 to 1.779, P=0.036; OS: HR=1.376, 95% CI: 1.035 to 1.825, P=0.028), pathological stage Ⅲ (DFS: HR=2.131, 95% CI: 1.444 to 3.144, P<0.01; OS: HR=2.079, 95% CI: 1.406 to 3.074, P<0.01), and no postoperative chemotherapy (DFS: HR=3.127, 95% CI: 2.377 to 4.113, P<0.01; OS: HR=3.768, 95% CI: 2.828 to 5.020, P<0.01) were independent prognostic factors for the decrease in DFS and OS rates. Conclusions:Laparoscopic radical gastrectomy for locally advanced gastric cancer with serosa-invasion could achieve satisfactory long-term oncological outcomes. More lymph node dissection and standardized postoperative adjuvant chemotherapy are expected to further improve the prognosis of patients with locally advanced gastric cancer with serous invasion after laparoscopic radical surgery.

Objective:To explore and analyze the efficacy of preoperative intravenous tranexamic acid (TXA) in reducing bleeding and alleviating early postoperative pain in elderly patients with proximal humeral fractures (PHF) who underwent minimally invasive plate osteosynthesis (MIPO) approach with open reduction and locking plate internal fixation.Methods:A retrospective analysis was conducted on the data of 165 elderly patients with partial or partial PHF who underwent open reduction and locking plate internal fixation via MIPO approach at the Yixing People′s Hospital from June 2018 to June 2021. According to whether TXA was used intravenously 30 minutes before surgery, patients were divided into a TXA group (77 cases) and a control group (88 cases). The surgical time, hemoglobin decrease, total blood loss (TBL), intraoperative blood loss (IBL), postoperative drainage volume, visible blood loss (VBL), hidden blood loss (HBL), blood transfusion status, Visual Analogue Scale (VAS) score for surgical site pain 24 hours after surgery, postoperative hospital stay, shoulder Constant-Murley function score at 1 and 3 months after surgery, and complications were recorded and compared between the two groups.Results:The TBL, VBL, IBL, HBL, postoperative drainage volume, hemoglobin decrease, transfusion rate, postoperative VAS score at the surgical site, and hospital stay in the TXA group were all lower than those in the control group, and the differences were statistically significant (all P<0.05). The VAS score at the surgical site 24 hours after surgery was positively correlated with TBL and HBL in two groups of patients ( r=0.402, 0.418, P<0.001). Compared with the control group, the TXA group had a higher shoulder Constant-Murley function score at 1 month after surgery, and the difference was statistically significant ( P=0.002). There was no statistically significant difference in shoulder Constant-Murley function score and incidence of complications between the two groups at 3 months after surgery (all P>0.05). Conclusions:For elderly patients with partial or partial PHF who underwent open reduction and locking plate internal fixation using MIPO approach, intravenous infusion of TXA 30 minutes before surgery can help alleviate postoperative pain at the surgical site, reduce intraoperative and postoperative bleeding, lower transfusion rates, shorten hospital stay, and do not increase the incidence of complications such as incision abnormalities and thrombosis, which is beneficial for promoting early and rapid recovery of patients.

Objective:To explore the independent risk factors for the occurrence and aggravation of lower back pain (LBP) in patients with Parkinson′s disease (PD), in order to provide reference for clinical diagnosis and treatment.Methods:A retrospective analysis was conducted on the case data of 309 PD patients who visited the Affiliated Yixing Hospital of Jiangsu University from June 2018 to May 2020. The KING Parkinson′s Disease Pain Scale (KPPS) was used to quantitatively evaluate the LBP of PD patients, who were divided into LBP group and Non LBP group. The general clinical data, PD related data, and imaging data of the two groups were compared and analyzed. Binary logistic regression analysis was used to evaluate independent risk factors for LBP in PD patients. Pearson correlation analysis was conducted between KPPS scores and various factors, and linear regression analysis was used to identify the relevant risk factors that exacerbate LBP in PD patients.Results:Compared with the Non LBP group, the LBP group had lower bone mineral density (BMD) and a lower proportion of patients who engaged in daily exercise. The difference between the two groups was statistically significant (all P<0.05). Compared with the Non LBP group, patients in the LBP group had a longer course of illness, higher stiffness scores, a higher proportion of patients with fluctuating symptoms, higher UPDRS-Ⅲ scores, and a higher proportion of patients with thoracolumbar fascial injury (TLFI) and lumbar sagittal imbalance. The differences between the two groups were statistically significant (all P<0.05). The results of binary logistic regression analysis showed that combined TLFI ( OR=2.773, 95% CI: 1.219-6.309, P=0.015), combined lumbar sagittal imbalance ( OR=4.835, 95% CI: 2.244-10.421, P<0.001), and lower BMD ( OR=2.818, 95% CI: 1.767-4.493, P<0.001) were risk factors for LBP in PD patients. The KPPS score was correlated with BMD and TLFI ( r=-0.146, 0.294, all P<0.05). The linear regression results showed that the merged TLFI ( B=2.271, β=0.285, P<0.001) was positively correlated with KPPS score, indicating a risk factor. Conclusions:The combination of TLFI, lumbar sagittal imbalance, and lower BMD is closely related to the occurrence of LBP in PD patients, and the combination of TLFI is an independent risk factor for exacerbating LBP symptoms. Clinical attention should be paid to the prevention and treatment of TLFI in PD patients.
