Osteosarcoma (OS) is the most prevalent primary malignant bone tumor affecting children and adolescents. Despite ongoing research efforts, the 5-year survival rate has remained stagnant for many years, highlighting the critical need for novel drug development to enhance current treatment protocols. Ziyuglycoside II (ZYG II), a triterpenoid saponin extracted from S. officinalis, has recently demonstrated antitumor properties. This study evaluates the antitumor effect of ZYG II on osteosarcoma and elucidates its mechanism of action through the co-regulation of p53 and estrogen-related receptor gamma (ESRRG), which inhibits disease progression. The research employs in vitro experiments using multiple established osteosarcoma cell lines, as well as in vivo studies utilizing a nude mouse model of orthotopic xenograft osteosarcoma. Additionally, ESRRG shRNA was used to construct stable ESRRG-reducing OS cell lines to investigate the molecular mechanism by which ZYG II exerts its anti-osteosarcoma effects through the co-regulation of ESRRG and p53. Results indicate that ZYG II administration led to decreased OS cell viability and reduced tumor volumes. Furthermore, cell cycles were arrested at the G₀/G₁ phase, while the proportion of apoptotic cells increased. Expression of p53, ESRRG, p21, Bax, Cleaved Caspase-9, and Cleaved Caspase-3 proteins increased, while expression of CDK4, Cyclin D1, and Bcl-2 proteins decreased. Multiple ZYG II and ESRRG docking patterns were simulated through molecular docking. Comparing the pharmacodynamic response of ZYG II to OS cell lines with reduced ESRRG and normal expression demonstrated that ZYG II inhibits osteosarcoma progression, induces cell cycle arrest, and promotes cell apoptosis through the coordination of p53 and ESRRG. In conclusion, ZYG II inhibits osteosarcoma progression, leads to cell cycle arrest, and promotes cell apoptosis through synergistic regulation of p53 and ESRRG.

Purpose To investigate the clinicopathological significance and prognostic value of oral cancer overexpressed 1(ORAOV1)in esophageal squamous cell carcinoma(ESCC).Methods The mRNA expression of ORAOV1,ERK1 and ERK2 in 140 ESCC and 39 esophageal squamous intraepithelial neoplasia(ESIN)and 140 adjacent normal mucosal tissues were detected by RT-PCR.The relationship between their overexpres-sion and clinicopathological features was analyzed in ESCC pa-tients.Spearman correlation analysis was used to explore the correlation between ORAOV1 and ERK1 and ERK2.Results The expression level of ORAOV1 mRNA(13.158±2.246)with ESCC was significantly higher than that of low-grade ESIN(4.974±1.317),high-grade ESIN(7.398±1.891)and adja-cent tissues(1.000±0).The differences were significant(P＜0.01).High expression of ORAOV1 mRNA was positively cor-related with ESCC clinical stage and lymph node metastasis(all P＜0.05).Spearman analysis showed that the expression level of ORAOV1 mRNA was positively correlated with the expression levels of ERK1 mRNA and ERK2 mRNA in ESCC.Kaplan-Meier survival curve analysis showed that the overall survival of ESCC patients with high expression of ORAOV1 was significantly lower than that of patients with low expression,and the differ-ence was significant(P＜0.05).Conclusion The expression level of ORAOV1 gradually increases during the occurrence and development of ESCC,which is an independent prognostic factor of ESCC and is expected to become a new molecular target for early diagnosis and treatment of ESCC.

ObjectiveTo explore the influence of electroacupuncture combined with point bloodletting and cupping for facial nerve function recovery in acute stage of idiopathic facial palsy （IFP）. MethodsEighty patients with IFP in the acute stage were randomly divided into 40 cases each in the treatment group and the control group. In the control group， oral prednisone acetate tablets were administered during the acute stage when the disease duration was less than 10 days； and electroacupuncture and flash cupping were provided during the recovery stage when the disease duration was more than 10 days， five times a week. For treatment group in acute stage， the stellate ganglion， vagus nerve stimulation point in the auricular cavity， Yifeng （TE 17） and Tinghui （GB 2） were needled on the affected side on the basis of the treatment of control group， with Yifeng and Tinghui connecting to electroacupuncture apparatus， once a day； point bloodletting and then cupping in Yifeng 2 times a week； in recovery stage， the treatment was the same as that of the control group. Both groups were treated until the 45th day from onset. The primary outcome was the Toronto facial grading system （SFGS）， and the secondary outcomes included house-brackmann （H-B） grade， facial disability index （FDI） score， and number of H-B grade-Ⅰ cases. Adverse events were recorded in both groups. ResultsThe SFGS scores of the patients in both groups were higher on the 10th， 30th and 45th days after onset of disease compared with those before the treatment （P＜0.05）； the H-B grade was lower on the 30th and 45th days after the onset of the disease compared with those before the treatment （P＜0.05）； and the facial disability index physical function （FDIP） and facial disability index social function （FDIS） scores were higher on the 30th and 45th days after onset of disease （P＜0.05）. SFGS scores of patients in the treatment group were significantly higher than those of the control group on the 30th and 45th days after onset （P＜0.05）； H-B grade was significantly lower than that of the control group on the 30th and 45th days after onset （P＜0.05）； and FDIP scores on the 45th day after onset， and FDIS scores on the 30th and 45th days after onset were significantly higher than those of the control group （P＜0.05）. At the end of treatment， 77.50% （31 cases） achieved H-B grade-Ⅰ in the treatment group， which was more than 55.00% （22 cases） in the control group （P＜0.05）. No adverse events occurred in either group. ConclusionElectroacupuncture combined with point bloodletting and cupping for IFP in acute stage can improve the recovery degree of facial nerve function， improve effectiveness， and show a high degree of safety.

Objective:To explore the potential categories of psychological distress in spousal caregivers of stroke patients and differences in quality of life between categories, in order to provide a theoretical basis for early clinical identification and provision of individualized and targeted interventions for psychological distress in spousal caregivers of stroke patients and improvement of their quality of life.Methods:A total of 207 spouse caregivers of stroke patients hospitalized in three class 1-Grade A hospitals in Yinchuan city of Ningxia Hui Autonomous Region, who met the inclusion and exclusion criteria were selected from December 2020 to July 2021 by convenience sampling method as study subjects. The general information questionnaire, Kessler Psychological Distress Scale, and the Mos 36-Item Short from Health Survey were used for a cross-sectional survey.Results:A total of 203 spousal caregivers of stroke patients were finally investigated, 46 males and 157 females with a age of (58.65 ± 9.66) years. Psychological distress among spousal caregivers of stroke patients was categorized into 3 potential categories:no distress group (40%, 81/203), listlessness group (45%, 91/203) and helplessness and restlessness group (15%, 31/203). The psychological distress subgroup was a factor influencing the quality of life of spousal caregivers of stroke patients ( t=-10.03, P<0.05), explaining 33.0% of the variance in quality of life. Conclusions:Psychological distress in spousal caregivers of stroke patients is significantly heterogeneous. Those in the helplessness and restlessness group have the lowest quality of life and should be given focused attention and early intervention.

Background: The purpose of this study is to describe the kinematic characteristics of manual weaving related to the biomechanical risk factors for musculoskeletal disorders. Methods: Twelve professional female weavers participated in this study. The video recording of their workstations was performed perpendicularly in the sagittal and transverse planes in a synchronized manner, at about 2.45 m and for 5 minutes. The videos were then analyzed using the Kinove software. Statistical processing by the statistical SPSS 22 software. Results: The results identified a succession of cycles, each with two important phases called the “interlacing” phase and the “winding/adjustment” phase. The average cycle time is 127.9 ± 11.7 seconds. The “interlacing” phase is the longest and concerns an average 80% of the cycle time or 103.5 ± 35.9 seconds. The segmental movements are mainly flexion-extension type with angular variations constantly above the acceptable limits. It is the same for the repetitiveness of the movements which solicit the upper limb and the trunk particularly. Conclusions These results recommend one of the actions to prevent musculoskeletal disorders including instructions on postures and frequencies of weaving movements as well as physical exercises adapted to the physical needs of practitioners.
