Objective: This study aimed to compare outcomes and adverse events of patients with locally advanced cervical cancer (LACC) undergoing concurrent chemoradiotherapy (CCRT) with cisplatin single-agent chemotherapy vs. CCRT with cisplatin combined with paclitaxel dualagent therapy. The primary outcomes are overall survival (OS), progression-free survival (PFS), local recurrence (LR), distant metastasis (DM) and the occurrence of adverse events. Methods: This retrospective cohort study included patients with FIGO 2009 stage IB1-IVA cervical squamous cell carcinoma undergoing radical CCRT. Patients were divided into groups A and B, treatment outcomes were compared between the two groups after 1:1 proportional propensity score matching. Results: Medical records of 1,203 patients were reviewed and 572 patients were finally included for propensity score matching. After propensity score matching, 121 pairs of patients were selected for analysis. The OS, PFS, LR and DM rates were 78.5% and 83.5% (p=0.417), 73.3% and 78.5% (p=0.312), 6.6% and 2.5% (p=0.123), 19% and 15.7% (p=0.497) for groups A and B, respectively. Further subgroup analysis according to stage and lymph node metastatic status showed no difference in survival between the two groups. The incidence of grade 3–4 acute haematological toxicities was different between the two groups (p<0.05). Conclusion Cisplatin combined with paclitaxel CCRT couldn’t improve the survival rates of patients with LACC. However, the hematological toxicity of combination chemotherapy is more severe but controllable. Cisplatin single-agent therapy remains the first choice for CCRT. Further prospective studies are indicated to provide evidence for the efficacy of cisplatin plus paclitaxel in dual-agent concurrent therapy.

Background::Cerebrovascular disease (CVD) ranks among the foremost factors responsible for mortality on a global scale. The mortality patterns of CVDs and temporal trends in China need to be well-illustrated and updated.Methods::We collected mortality data on patients with CVD from Chinese Center for Disease Control and Prevention’s Disease Surveillance Points (CDC-DSP) system. The mortality of CVD in 2020 was described by age, sex, residence, and region. The temporal trend from 2013 to 2019 was evaluated using joinpoint regression, and estimated rates of decline were extrapolated until 2030 using time series models.Results::In 2019, the age-standardized mortality in China (ASMRC) per 100,000 individuals was 113.2. The ASMRC for males (137.7/10 5) and rural areas (123.0/10 5) were both higher when stratified by gender and urban/rural residence. The central region had the highest mortality (126.5/10 5), the western region had a slightly lower mortality (123.5/10 5), and the eastern region had the lowest mortality (97.3/10 5). The age-specific mortality showed an accelerated upward trend from aged 55-59 years, with maximum mortality observed in individuals over 85 years of age. The age-standardized mortality of CVD decreased by 2.43% (95% confidence interval, 1.02-3.81%) annually from 2013 to 2019. Notably, the age-specific mortality of CVD increased from 2013 to 2019 for the age group of over 85 years. In 2020, both the absolute number of CVD cases and the crude mortality of CVD have increased compared to their values in 2019. The estimated total deaths due to CVD were estimated to reach 2.3 million in 2025 and 2.4 million in 2030. Conclusion::The heightened focus on the burden of CVD among males, rural areas, the central and western of China, and individuals aged 75 years and above has emerged as a pivotal determinant in further decreasing mortalities, consequently presenting novel challenges to strategies for disease prevention and control.

Objective:To develop three tDCS protocols based on the gait-related brain networks:the frontoparietal net-work(FPN),the dorsal-attention network(DAN),and the default network(DN),with the aim of specifical-ly modulating gait speed and gait variability and improving walking function. Method:In this study,healthy adults were recruited and randomly divided into 3 groups receiving different stimulation protocols:simultaneously enhancing the excitability of FPN and suppressing the excitability of DN(i.e.,FPN+/DN-tDCS),enhancing the excitability of DAN and suppressing the excitability of DN(i.e.,DAN+/DN-tDCS),and sham stimulation(Sham group).Normal,fast and dual-task gait tests were performed immediately before/after electrical stimulation,and spatiotemporal parameters and variability indicators of gait were collected.Two-way repeated measures ANOVA was used to assess the effects of three stimulation on gait characteristics under different conditions. Result:A total of 72 subjects were included in this study,64 of whom completed all tests.There were no significant interaction effects observed on gait spatiotemporal parameters in three conditions(normal,fast,dual-task walking conditions)and gait variability in normal walking between pre-and post-intervention assessments.In the fast gait task,there were significant interaction effects observed for stride length variability(F=3.671,P=0.031)and double support time variability(F=3.879,P=0.026).In the dual-task gait task,there were signif-icant interaction effects observed for stride width variability(F=3.940,P=0.025),gait speed variability(F=3.936,P=0.025),and double support time variability(F=4.913,P=0.011). Conclusion:The DAN+/DN-tDCS protocol were effective in reducing gait variability and improving gait stabili-ty during complex tasks in healthy adults.However,the FPN+/DN-tDCS protocol did not specifically improve gait speed under different conditions.

AIM To investigate the flavor technology for Jiannaoning Mixture based on electronic tongue combined with preference index.METHODS Artificial sensory evaluation method was employed to screen the type of flavor agents,electronic tongue was applied to screening the consumption of flavor agents,and double-bottle preference test was adopted in the analysis of effects of rat gender and body weight on taste sensitivity,after which acceleration test was conducted.RESULTS Sucrose,stevioside and xylitol were taken as flavor agents,whose optimal consumptions were 15%,0.08%and 15%,respectively.Male rats demonstrated stable taste perception with the body weights of 220-280 g,and 0.08%stevioside displayed the best flavoring effect.After placed under accelerated condition for 3 months,the preparation exhibited stable appearance,pH value and contents of lobetyolin,salvianolic acid B,schizandrin,ruscogenin.CONCLUSION This stable and reliable method can provide reference for improving the terrible tastes of Jiannaoning Mixture and other oral liquid preparations of traditional Chinese medicines.

Objective To analyze the impact of mini plate and cannulated screw internal fixation on joint function recovery in patients with posterior malleolus fracture.Methods A total of 150 patients with posterior malleolus fractures,treated at our hospital from March 2021 to June 2023,were included in this study.They were divided into two groups using the odd-even number method.The control group consisted of 75 patients who underwent cannulated screw internal fixation,while the study group comprised 75 patients who received mini plate internal fixation.Clinical indicators,ankle range of motion,ankle function,and health status were compared and analyzed between the two groups.Additionally,levels of inflammatory factors,postoperative complications,and clinical efficacy were assessed.Results In terms of operation time and intraoperative blood loss,there was no statistically significant difference between the two groups(P＞0.05).However,the study group exhibited shorter ambulation days,fracture healing time,and hospitalization days compared to the control group(P＜0.05).Moreover,the study group demonstrated significantly improved ankle dorsiflexion,ankle plantar flexion,foot varus and foot valgus range of motion compared to the control group(P＜0.05).Additionally,higher AOFAS score and KPS score were observed in the study group as compared to the control group(P＜0.05).Furthermore,levels of IL-6,IL-8 and CRP were lower in the study group than in the control group(P＜0.05).The incidence of postoperative complica-tions was also lower in the study group than in the control group(P＜0.05).Conclusion Mini plate internal fixa-tion for posterior malleolus fracture yields ideal outcomes by promoting improvement in clinical indicators and ankle range of motion while effectively enhancing ankle function,reducing inflammatory reaction as well as minimizing postoperative complications.

Bone formation and deposition are initiated by sensory nerve infiltration in adaptive bone remodeling. Here, we focused on the role of Semaphorin 3A (Sema3A), expressed by sensory nerves, in mechanical loads-induced bone formation and nerve withdrawal using orthodontic tooth movement (OTM) model. Firstly, bone formation was activated after the 3rd day of OTM, coinciding with a decrease in sensory nerves and an increase in pain threshold. Sema3A, rather than nerve growth factor (NGF), highly expressed in both trigeminal ganglion and the axons of periodontal ligament following the 3rd day of OTM. Moreover, in vitro mechanical loads upregulated Sema3A in neurons instead of in human periodontal ligament cells (hPDLCs) within 24 hours. Furthermore, exogenous Sema3A restored the suppressed alveolar bone formation and the osteogenic differentiation of hPDLCs induced by mechanical overload. Mechanistically, Sema3A prevented overstretching of F-actin induced by mechanical overload through ROCK2 pathway, maintaining mitochondrial dynamics as mitochondrial fusion. Therefore, Sema3A exhibits dual therapeutic effects in mechanical loads-induced bone formation, both as a pain-sensitive analgesic and a positive regulator for bone formation.
