Objective To evaluate the short-term efficacy and safety of catheter-directed thrombolysis(CDT)via femoral vein access and via anterior tibial vein access for lower extremity deep vein thrombosis(LEDVT).Methods The clinical data of 86 LEDVT patients,who were treated with CDT via healthy-side femoral vein access or via affected-side anterior tibial vein access at the Second Affiliated Hospital of Nanjing Medical University of China between January 2019 and December 2021,were retrospectively analyzed.Of the 86 patients,via femoral vein access was adopted in 40(FV group)and via anterior tibial vein access was adopted in 46(ATV group).The primary endpoints were the technical success rate and the thrombus removal rate.The secondary endpoints included the operation time and the complications.Results In the FV group and ATV group,the technical success rates were 92.5％and 100％respectively(P=0.097),the thrombus removal rates were(68.9+25.9)％and(78.3±21.0)％respectively(P=0.067),and the differences between the two groups were not statistically significant.The operation time in the FV group and ATV group was(64.1±14.8)min and(72.0±19.9)min respectively(P=0.037),and the difference between the two groups was statistically significant.The incidence of complications in the FV group and ATV group was 22.5％and 10.9％respectively(P=0.145),and the difference between the two groups was not statistically significant.Conclusion CDT therapy,regardless of via femoral vein access or via anterior tibial vein access,can effectively treat LEDVT with quite same clinical short-term efficacy and safety.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

Objective To investigate the effect of Yiqi Jiedu Recipe(YQ)on the proliferation,migration,and invasion of nasopharyngeal carcinoma cells,and to explore its mechanisms of action on proliferation,migration,and invasion through the TGF-β1/SMAD3 signaling pathway.Methods(1)The 5-8F cells were divided into four groups:solvent control group,YQ 0.5 mg·mL-1 group,YQ 1.0 mg·mL-1 group,and 5-fluorouracil 2 μg·mL-1 group.Cell proliferation was monitored using real-time cell analysis(RTCA).Wound healing experiment was conducted to assess cell migration.After 24 hours of drug intervention,transwell assay was employed to measure cell invasion.The protein expression levels of β-catenin,E-cadherin,N-cadherin,TGF-β1,and SMAD3 in the cells were evaluated using the Western Blot method.(2)The 5-8F cells were divided into five groups:solvent control group,TGF-β1 10 ng·mL-1 group,TGF-β1 10 ng·mL-1+YQ 1.0 mg·mL-1 group,YQ 1.0 mg·mL-1 group,and LY3200882 10 μmol·L-1 group.Cell proliferation was monitored using RTCA.Wound healing experiment was conducted to assess cell migration.After 24 hours of drug intervention,transwell assay was employed to measure cell invasion.The protein expression levels of β-catenin,E-cadherin,N-cadherin,TGF-β1,and SMAD3 in the cells were evaluated using Western Blot.(3)The nude mice were randomly assigned into the model group,YQ group,and 5-fluorouracil group.Subcutaneous injection of 5-8F cell suspension was performed to establish the xenograft nude mouse model of nasopharyngeal carcinoma.After the tumors reached a certain size,the 5-fluorouracil group received intraperitoneal injection of 5-Fu once every 2 days,while the other groups were orally administered corresponding drugs once a day for three consecutive weeks.Tumor volume was measured every 3 days.Western Blot was conducted to assess the protein expression levels of β-catenin,E-cadherin,and N-cadherin in the tissues of each group.Results Compared with the solvent control group,the proliferation curves of 5-8F cells in the YQ(0.5 mg·mL-1,1.0 mg·mL-1)groups showed a decrease.The migration and invasion abilities of the cells were both reduced(P＜0.05,P＜0.01).Additionally,the expression of E-cadherin protein significantly increased(P＜0.01),while the protein expression of β-catenin,N-cadherin,TGF-β1,and SMAD3 all decreased(P＜0.05,P＜0.01).Compared with the model group,the transplanted tumor volume of nasopharyngeal carcinoma in the YQ group significantly decreased(P＜0.05).Furthermore,the protein expression of β-catenin and N-cadherin in the transplanted tissues of the YQ group was significantly downregulated(P＜0.05,P＜0.01),while the expression of E-cadherin protein was significantly upregulated(P＜0.01).After the addition of the activator and inhibitor of TGF-β1 signaling pathway,compared with the YQ 1.0 mg·mL-1 group,the TGF-β1 10 ng·mL-1+YQ 1.0 mg·mL-1 group showed a significant increase in the expression of TGF-β1,SMAD3,β-catenin,and N-cadherin proteins(P＜0.05,P＜0.01)and obvious enhancement of the abilities of cell proliferation,migration,and invasion(P＜0.01).Conclusion Yiqi Jiedu Recipe can inhibit the proliferation,migration,and invasion by regulating the TGF-β1/SMAD3 signaling pathway.

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.

BACKGROUND: Most Chinese migrants have been faced with obstacles to getting access to local public health services. Young migrants among internal migrants make a major contribution to the economy. However, the establishment of their health records has been ignored. This research was aimed at exploring the status and associated factors of the establishment of health records among young Chinese migrants. METHODS: Data were obtained from the 2017 China Migrants Dynamic Survey (CMDS). Chi-square test and binary logistic regression were performed to investigate the associated factors of the establishment of health records among young Chinese migrants. RESULTS: Approximately 30.2% of young migrants had their health records established in inflow communities. Urban residence, medical insurance (insured), and lower average monthly household income were attributed to the establishment of more health records. Young migrants who were in northeast China and across provinces and immigrated for working or engaging in trade were less likely to have health records established. Young migrants who participated in social activities and public affairs activities and took type of people in touch as natives in the inflow area showed a higher possibility of establishing health records. Meanwhile, receiving health education and hearing about national basic public health services (BPHSs) were beneficial for establishing the health records of more young migrants. CONCLUSION This study showed that the health records of young migrants had a relatively low establishment rate. Sociodemographic and migration characteristics, health status, public health services, and social integration factors were all related to the health record establishment of young Chinese migrants.

Objective:To study the biological behavior of nasopharyngeal carcinoma stem cells and to explore the activation of Ras signaling pathway regulated by CD44.Methods:CNE2-SC and 5-8F-SC were nasopharyngeal carcinoma stem cells and obtained by serum-free suspension culture. Cell counting kit-8 (CCK-8) assay, colony formation assay, Transwell migration assay, cell adhesion array were used to investigate the growth, proliferation, migration and adhesion of nasopharyngeal carcinoma stem cells. Western blot test was used to detect the expressions of Ras signaling pathway related proteins and siRNA-mediated interference was used to determine the activation of Ras signaling pathway regulated by CD44.Results:The growth rates of CNE2-SC and 5-8F-SC cells were significantly lower than those of nasopharyngeal carcinoma cells at 24, 48 and 72 hours after inoculation ( P<0.05). After 14 days of implantation, the colony formation rates of CNE2-SC (44.5±1.9)% and 5-8F-SC (47.4±1.8)% were higher than those of CNE2 (34.9±1.5)% and 5-8F (37.2±1.7)%, respectively( P<0.01). The migration cell number of CNE2-SC was (87.6±7.8), 3.97 times higher than that of CNE2 ( P<0.01). The migration cell number of 5-8F-SC was (67.2±5.7), 3.07 times higher than 5-8F ( P<0.01). The adhesion rates of CNE2-SC and CNE2 cells were (42.1±7.6)% and (8.9±2.0)%, respectively at 3 hours after inoculation and were (82.4±5.0)% and (12.1±2.2)% at 6 hours after inoculation, respectively. The adhesion rate of CNE2-SC cells was higher than that of CNE2 cells (all P<0.01). The adhesion rates of 5-8F-SC and 5-8F cells were (53.6±6.1)% and (7.3±1.5)% at 3 hours after inoculation, and (90.7±3.6)% and (11.0±1.2)% at 6 hours after inoculation, respectively. The adhesion rate of 5-8F-SC cells was higher than that of 5-8F cells ( P<0.01). The expression levels of CD44, Ras and N-cadherin were significantly higher, while phosphatase and tensin homolog deleted on chromosome 10 (PTEN), E-cadherin in nasopharyngeal carcinoma stem cells were lower than those of the nasopharyngeal carcinoma cells. Furthermore, the levels of phosphorylated mitogen extracellular kinase1/2 (p-MEK1/2) and phosphorylated extracellular signal-regulated protein kinase1/2 (p-ERK1/2)were significantly increased in nasopharyngeal carcinoma stem cells ( P<0.01). Correlation analysis showed that the protein expression levels of CD44 was highly positively correlated with RAS in nasopharyngeal carcinoma stem cells( r=0.985, P=0.002; r=0.962, P=0.038). Deletion of CD44 in CNE2-SC decreased the expression levels of HER-2, Ras and p-ERK1/2, p-Akt and phosphorylated protein kinase C-δ(p-PKCδ) ( P<0.01). Conclusions:Despite compare to the nasopharyngeal carcinoma cell, nasopharyngeal carcinoma stem cells grows at a relatively slow rate, the capacities of clone formation, migration, adhesion are promoted. This may be related to the CD44-regulated abnormal activation of Ras signaling pathway.

BACKGROUND: Limited published research has examined the relationships of negative life events and coping styles with sleep quality in Chinese junior high school students. We aimed to investigate the prevalence of poor sleep quality and to clarify the role of coping styles between negative life events and sleep quality. METHODS: A cross-sectional study of 3081 students was conducted in Ganzhou City, Jiangxi Province, Southeastern China. Adolescent Self-Rating Life Events Checklist, Simplified Coping Style Questionnaire, and Pittsburg Sleep Quality Index were applied to assess negative life events, coping styles, and sleep quality, respectively. Descriptive analyses, independent-samples t tests, one-way analyses of variance, Pearson correlation analyses, and structural equation modeling (SEM) were applied to analyze the data. RESULTS: The prevalence of poor sleep quality was 26.7%. Negative life events (B = 0.038, P < 0.001) and negative coping style (B = 0.049, P < 0.001) demonstrated a positive association with poor sleep quality, while positive coping style indicated a negative association with poor sleep quality (B = -0.029, P < 0.001). Interactions of negative life events and coping styles with sleep quality were not found (all P > 0.05). The association between negative life events and sleep quality was mediated by negative coping styles. CONCLUSIONS Our results indicated that poor sleep quality was common in these Chinese adolescents. Negative life events and negative coping style were associated with an increased prevalence of poor sleep quality, while the positive coping style was related to a decreased prevalence of poor sleep quality. A negative coping style mediated the association between negative life events and sleep quality.
