Objective:To investigate the clinicopathological characteristics and prognostic influencing factors in young breast cancer patients.Methods:A retrospective case series study was conducted. The clinical data of 408 young patients with breast cancer in the Fifth Medical Center of Chinese PLA General Hospital from January 2005 to December 2020 were retrospectively analyzed. The clinical characteristics and prognostic influencing factors of patients were observed. The Kaplan-Meier method was used to analyze overall survival (OS) and disease-free survival (DFS) of patients. Univariate analysis of prognostic factors was conducted by using the log-rank test, and multivariate analysis was performed by using Cox proportional risk model.Results:The median age [ M ( Q1, Q3)] of 408 young female patients with breast cancer was 36 (33, 39) years; the 5-year OS and 5-year DFS rates were 89.9%, 84.0% of 387 breast cancer patients in early and middle stage (except for stage Ⅳ). There were statistically significant differences in the 5-year OS and 5-year DFS rates (excluding stage Ⅳ of DFS) of patients with different clinical staging and molecular subtypes (all P < 0.05). The differences were statistically significant in the 5-year DFS rate of patients with different pathological types and histological grades (all P < 0.05). There were no statistically significant differences in the 5-year OS and DFS rates between the patients receiving breast-conserving surgery or mastectomy (all P > 0.05). The results of multivariate Cox regression analysis indicated that clinical staging ( HR = 3.121, 95% CI: 2.301-4.233, P < 0.001) and molecular classification ( HR = 1.441, 95% CI: 1.126-1.845, P = 0.004) were independent prognostic factors for OS. Additionally, clinical staging ( HR = 3.001, 95% CI: 2.174-4.141, P < 0.001) was identified as an independent prognostic factor for DFS. Conclusions:The prognosis of young breast cancer patients is closely related to clinical staging and molecular subtype. The later the clinical stage is, the poorer prognosis is. Luminal-type breast cancer has a better prognosis than other subtypes. For early-stage breast cancer patients who meet the criteria for breast-conserving surgery, breast-conserving surgery is the first-choice alternative.

Objective To investigate the relationship between cystatin C(CysC)/prealbumin(PAB)ratio and lung function and chronic obstructive pulmonary disease(COPD)assessment test(CAT)score in patients with COPD.Methods A total of 216 COPD patients admitted to the hospital from February 2021 to February 2024 were selected as the study group,and 150 healthy subjects were selected as the control group during the same period.CysC and PAB levels were detected by immunoturbidimetry,CysC/PAB ratio was calculated,lung function was detected and CAT scores were recorded.Pearson correlation was used to analyze the rela-tionship between CysC/PAB ratio,lung function and CAT score in COPD patients.Results The CysC and CysC/PAB ratio in the study group was significantly higher than that in the control group,and the level of PAB was significantly lower than that in the control group,with statistical significance(P＜0.05).The forced expiratory volume in the first second as a percentage of predicted value(FEV1％pred),the percentage of pre-dicted forced vital capacity(FVC％pred)and the ratio of the first second forced expiratory volume to forced vital capacity(FEV1/FVC)of the study group were lower than those of the control group,and the CAT score of the study group was higher than that of the control group,with statistical significance(P＜0.05).The Cy-sC/PAB ratio and CAT score of COPD patients with the global initiative for chronic obstructive lung disease(GOLD)grade 4 were significantly higher than those with GOLD grade 3,GOLD grade 2 and GOLD grade 1,and the difference was statistically significant(P＜0.05).The ratio of CysC/PAB in very severely affected pa-tients was higher than that in severely affected,moderately affected and mildly affected patients,while the ra-tio of FEV1％pred,FVC％pred and FEV1/FVC was lower than that in severely affected,moderately affected and mildly affected patients,and the difference was statistically significant(P＜0.05).In COPD patients,Cy-sC/PAB ratio was negatively correlated with FEV1％pred,FVC％pred,FEV1/FVC,and positively correlated with CAT score(P＜0.05).Conclusion CysC/PAB ratio is highly expressed in COPD patients,and its level is related to lung function and CAT score,which can reflect the degree of disease and quality of life in COPD patients to a certain extent.

This study evaluates the safety and early clinical outcomes of a novel 3D-printed titanium alloy "sleeve" component for revising fractured femoral stem prostheses in distal femoral megaprostheses without removing the fractured stem. The six patients included 2 males and 4 females, with an age range of 8-57 years. They were treated at Peking University People's Hospital between August 2020 and December 2023 and underwent revision surgery using the customized sleeve. A self-designed 3D-printed titanium alloy "sleeve" component was used for revision without removing the fractured stem, in the form of an external sleeve around the stem. Postoperative imaging was performed every three months to assess implant stability and bone integration. Functional outcomes were evaluated using the Musculoskeletal Tumor Society (MSTS)-93 score. All six patients successfully completed the surgery and follow-up, with surgical durations ranging from 120 to 230 minutes and intraoperative blood loss ranging from 150 to 800 ml. The follow-up period ranged from 6 to 46 months. At three months postoperatively, X-ray and CT imaging showed cortical bridging between the host bone and the "sleeve" component. By six months, full integration of the host cortical bone with the metal trabecular interface of the "sleeve" was observed. At the final follow-up, MSTS-93 scores ranged from 26 to 29 points, with no complications such as wound healing issues, implant loosening, fracture, infection, or degenerative arthritis. These findings suggest that 3D-printed titanium "sleeve" provide an effective, bone-preserving solution for femoral stem revision in oncologic megaprostheses, leading to favorable early stability and functional recovery.

Objective:To observe the improving effect of acupuncture and Tuina(Chinese therapeutic massage)combined with Ba Duan Jin(Eight-brocade Exercise)on motor function in patients with Parkinson disease(PD)in the early and middle stages.Methods:Seventy patients with early-or middle-stage PD were randomly divided into a control group and an observation group,with 35 patients in each group.The control group was given conventional treatment such as oral levodopa hydrochloride tablets;the observation group was treated with acupuncture,Tuina,and Ba Duan Jin in addition to the control group's treatment.Acupuncture and Tuina were administered twice a week,and Ba Duan Jin was performed five times a week.Each course of treatment lasted 4 weeks,and a total of 3 courses were completed.The changes in the unified Parkinson disease rating scale Ⅲ(UPDRS Ⅲ)score,Berg balance scale(BBS)score,15-meter walking speed,and 6-minute walk distance were compared between the two groups.Results:The total effective rate in the observation group was 93.6%,which was significantly higher than 45.7%in the control group(P<0.01).After 4,8,and 12 weeks of treatment,the UPDRS Ⅲ score in the observation group was significantly lower than the previous score(P<0.05);the BBS score was significantly higher than the previous score(P<0.05),and the 6-minute walk distance also significantly increased compared to the previous result(P<0.05).After 8 and 12 weeks of treatment,the 15-meter walking speed in the observation group was significantly higher than that before treatment and the previous measurement(P<0.05).In comparison with the control group,the observation group showed significantly lower UPDRS Ⅲ scores after 8 and 12 weeks of treatment(P<0.05).Additionally,after 4,8,and 12 weeks of treatment,the observation group had significantly higher BBS scores,15-meter walking speed,and the 6-minute walk distance than the control group(P<0.05).There were no significant differences in the above indicators before and after treatment in the control group(P>0.05).Conclusion:The addition of acupuncture,Tuina,and Ba Duan Jin to Western medication treatment can effectively improve motor function,balance ability,and walking ability in patients with early-or middle-stage PD.

Objective To explore prescription medication rules and potential mechanism of traditional Chinese medicine(TCM)in the treatment of alcoholic liver disease(ALD)based on the technology of data mining and network pharmacology.Methods The prescriptions related to the treatment of ALD were retrieved in Chinese National Knowledge Infrastructure,Wanfang,Chinese Biomedical Literature and VIP databases.After the data were collated according to the filter criteria,IBM SPSS Statistics 27.0 and IBM SPSS Modeler 18 software were used to analyze the prescription rules and association rules.Then,the medication rules of TCM in the treatment of ALD were summarized,and the core drug combinations were obtained.Active ingredients in the core drug combinations for ALD and their targets were screened by network pharmacology.GO and KEGG analysis were performed on the main targets,and molecular docking technique was used to verify the binding ability of active ingredients to main targets.Results A total of 143 prescription for ALD were screened,involving 222 Chinese medicine,among which 28 high-frequency Chinese medicine were used with a frequency≥25 times.Eight core drug combinations were obtained by associations rule analysis.It has been found that there are 215 intersection targets between"Poria-Atractylodis macrocephalae Rhizoma-Hearba Artemisiae Scopariae"and ALD,including six core targets of AKT1,TNF,VEGFA,IL-1β,SRC,EGFR.One hundred and sixty-eight of signaling pathways are involved,including cancer pathways,PI3K/AKT signaling pathways,chemical carcinogenesis-reactive oxygen species,lipid and atherosclerosis,etc.Molecular docking results showed that the main active components including cerevisterol,genkwanin and demethoxycapillarisin had good binding ability to AKT1.Conclusion The main active ingredients in"Poria-Atractylodis macrocephalae Rhizoma-Hearba Artemisiae Scopariae"can participate in the regulation of key signaling pathways such as PI3K/AKT by acting on key target proteins(AKT1,TNF,and VEGFA).Subsequently,they play a role in inhibiting inflammatory response and apoptosis,slowing down liver fibrosis,and promoting hepatocyte repair.This study provides data support and theoretical guidance for the study of TCM in the treatment of ALD.

Diabetic nephropathy(DN)is one of the most serious microangiopathies in diabetes mellitus and the leading cause of death in patients with end-stage renal disease.Ferroptosis,as a mode of programmed cell death,is mainly manifested by excessive accumulation of intracellular lipid peroxides and iron.Ferroptosis is involved in a series of pathological processes such as damage to DN renal podocytes,mesangial cells,and renal tubular epithelial cells.Chinese materia medica has the characteristics of significant therapeutic effects and minimal adverse reactions in the treatment of diseases,and has been widely used in the prevention and treatment of DN.This article summarized the key factors regulating ferroptosis in DN,as well as the active components and TCM formulas targeting the inhibition of ferroptosis in the prevention and treatment of DN,providing reference for the development of DN targeted drugs.

Objective:To explore the efficacy of secondary targeted percutaneous vertebroplasty (PVP) for the treatment of refracture of injured vertebrae after vertebral augmentation for osteoporotic vertebral compression fracture (OVCF).Methods:A retrospective case series study was performed on the clinical data of 25 patients with refracture of injured vertebrae after vertebral augmentation for OVCF admitted to Honghui Hospital, Xi′an Jiaotong University from January 2019 to January 2022, including 10 males and 15 females, aged 62-86 years [(73.8±5.2)years]. The fractured segments involved T 10 in 1 patient, T 11 in 2, T 12 in 10, L 1 in 10 and L 2 in 2. All the patients were treated with secondary targeted PVP. The operation time and the amount of bone cement injected were recorded. The visual analogue scale (VAS) of lower back, Oswestry disability index (ODI), vertebral body index (VBI) and kyphotic angle (KA) were compared before surgery, at 1 day, 6 months after surgery and at the last follow-up. Odom criteria were used to evaluate the efficacy of the surgical procedure at the last follow-up. The intraoperative bone cement leakage and new vertebrae fracture during follow-up were observed. Results:All the patients were followed up for 23-59 months [(36.8±7.6)months]. The operation time was 35-60 minutes [(42.6±5.2)minutes], with the amount of bone cement injected for 3-5 ml [(3.6±0.8)ml]. The VAS scores of lower back at 1 day, 6 months after surgery and at the last follow-up were 3.1(2.0, 4.0)points, 1.7(1.0, 2.0)points and 0.6(0.0, 1.0)points respectively, significantly lower than 7.6(7.0, 9.0)points before surgery ( P<0.01), and a statistically singnificant decrease was found over follow-up time ( P<0.01). The ODI values at 1 day, 6 months after surgery and at the last follow-up were (49.5±5.9)%, (28.5±4.6)% and (19.2±4.8)% respectively, significantly lower than (78.8±6.8)% before surgery ( P<0.01), and a statistically singnificant decrease was found over follow-up time ( P<0.01). The VBI values at 1 day, 6 months after surgery and at the last follow-up were (76.6±4.5)%, (76.3±4.0)% and (76.1±3.8)% respectively, significantly higher than (58.9±5.8)% before surgery ( P<0.01), while there were no significant differences among those at 1 day, 6 months after surgery and at the last follow-up ( P>0.05). The KA values at 1 day, 6 months after surgery and at the last follow-up were (12.4±2.7)°, (12.6±2.5)° and (12.8±2.9)° respectively, significantly lower than (20.8±3.6)° before surgery ( P<0.01), while there were no significant differences among those at 1 day, 6 months after surgery and at the last follow-up ( P>0.05). According to the Odom criteria, 20 patients were rated excellent and 5 good at the last follow-up, with an excellent and good rate of 100%. Intraoperative asymptomatic bone cement leakage occurred in 3 patients (12%), including 2 with intervertebral leakage and 1 with lateral vertebral leakage. No adjacent vertebral body or other vertebral fracture was observed during the follow-up. Conclusions:For patients with refracture of injured vertebrae after vertebral augmentation for OVCF, the secondary targeted PVP has advantages of attenuation of the lower back pain, improvement of the quality of life, restoration of the height of refractured vertebrae, correction of the local kyphosis, and a low incidence of complications.
