Thoracolumbar spine fracture often leads to severe pain, functional impairments, and neurological deficits, for which open reduction and internal fixation can effectively restore the spinal structural stability. Open decompression and reduction with internal fixation can help relieve spinal cord compression and improve spinal function in cases of concomitant cord injury. Although spinal stability can be restored through surgery, patients often face chronic pain and functional impairments postoperatively. A postoperative rehabilitation program is critical in optimizing therapeutic outcomes, reducing complications, and minimizing the risk of secondary injuries. However, current rehabilitation methods, such as physical therapy, functional training, and pain management, are confronted with problems in clinical practice, including significant variation in efficacy, poor patient adherence, and prolonged rehabilitation period. There is an urgent need for a unified rehabilitation strategy to address these problems. To this end, the Spinal Trauma Group of the Orthopedic Physicians Branch of the Chinese Medical Association and the Spine Health Professional Committee of the Chinese Human Health Technology Promotion Association organized experts from relevant fields to formulate Evidence-based guidelines for rehabilitation treatment after internal fixation of thoracolumbar spine fracture in adults ( version 2025) by integrating evidences from clinical researches and advanced rehabilitation concepts at home and abroad. A total number of 14 recommendations concerning the rehabilitation treatment with multimodal analgesia, psychological intervention, deep vein thrombosis prevention, core muscle and extremity exercise, appropriate use of braces, early weight-bearing, device-aided rehabilitation exercise, neuroregulatory therapy, rehabilitation team were put forward, aiming to standardize the post-operative rehabilitation process following internal fixation, promote the functional recovery, and enhance patients′ quality of life.

Objective:To investigate the long-term efficacy, safety and prognostic factors of intraoperative radiotherapy (IORT) for narrow-margin (resection margin < 1 cm) hepatectomy in patients with hepatocellular carcinoma (HCC) during radical surgery.Methods:A retrospective cohort study was conducted. The data of primary HCC patients undergoing radical surgery and narrow-margin hepatectomy IORT in the Cancer Hospital of the Chinese Academy of Medical Sciences from November 2009 to February 2019 were collected. IORT applied 6 MeV or 9 MeV electron beams and a single irradiation was given to the margin. Kaplan-Meier method was used for the overall survival (OS) and disease-free survival (DFS) analysis; log-rank test was used for survival comparison among subgroups. The recurrence patterns and adverse reactions were recorded. Univariate and multivariate Cox proportional hazards models were used to analyze the factors influencing the OS and DFS.Results:A total of 64 patients were enrolled, with the median age [ M ( Q1, Q3)] of 57 years (49, 63) years. All patients included 55 males (85.9%) and 9 females (14.1%). The median dose of IORT was 15 Gy (range: 12-17 Gy). The median follow-up time was 83.3 (64.4, 91.9) months. The 1-year, 3-year, 5-year, 7-year, 10-year OS rates were 90.4%, 80.6%, 75.5%, 71.4% and 47.6%, respectively; the 1-year, 3-year, 5-year, 7-year,10-year DFS rates were 77.8%, 68.1%, 59.6%, 57.6% and 38.4%, respectively. Univariate Cox regression analysis indicated that preoperative serum alpha-fetoprotein (AFP) > 400 ng/ml was an independent risk factor for poor OS (> 400 ng/ml vs. ≤ 400 ng/ml: HR = 6.57, 95% CI: 2.16-19.96, P < 0.001), while not the independent influencing factor of poor DFS ( HR = 1.71, 95% CI: 0.65-4.52, P = 0.277). The age ≤ 60 years or not, gender, viral hepatitis or not, American Joint Committee on Cancer stage, tumor diameter (> 5 cm or not), tumor number, degree of tumor differentiation, microvascular invasion or not, microsatellite nodules or not, anatomical liver resection or not, and the dose of IORT ≤15 Gy or not were not the independent influencing factors of poor OS and DFS (all P > 0.05). Kaplan-Meier method analysis showed that patients with preoperative serum AFP ≤ 400 ng/ml (48 cases) had better OS compared with those with preoperative serum AFP>400 ng/ml (16 cases) (5-year OS rate: 84.8% vs. 44.9%; 7-year OS rate: 79.9% vs.37.4%), and the difference was statistically significant ( P = 0.002). There was no statistically significant difference in the DFS between the 2 groups ( P = 0.134). During the follow-up, 28 patients (43.8%) relapsed, including 17 cases (26.6%) of early recurrence and 11 cases (17.2%) of late recurrence. No marginal recurrence was observed. There were 22 cases (34.4%) of intrahepatic recurrence alone, 2 cases (3.1%) of extrahepatic recurrence and 4 cases (6.3%) of stimutaneous recurrence inside and outside the liver. The 1-, 3-, 5- and 7-year cumulative recurrence rates inside the liver were 19.0%, 27.2%, 37.4% and 39.3% respectively, and the cumulative recurrence rates outside the liver were 6.4%, 8.0%, 9.6% and 9.6% respectively. There were no adverse reactions above grade 3 in the entire group. There were no surgery-related deaths within 30 d after the operation, and no radiation-induced liver disease occurred. Conclusions:Narrow-margin IORT helps HCC patients receiving hepatectomy to achieve favorable long-term survival and adverse reactions are tolerable. It can be used as a safe and effective adjuvant therapy alternative.

A qualitative analysis by high-performance liquid chromatography coupled with time-of-flight mass spectrometry (HPLC-QTOF-MS/MS) was performed for the identification of main constituents in Gentiana veitchiorum. High-performance liquid chromatography (HPLC) was developed for the quantification of seven major components, including loganic acid (1), swertiamarin (2), gentiopicroside (3), sweroside (4), isoorientin (5), isoscoparin (6), and gentiournoside A (7). A total of 42 compounds, including 31 flavonoids, and 11 Iridoids, were identified based on their retention behaviors, and MS fragment information. Furthermore, regression equations for these seven chemical components were established, with good linear relationships (r2 > 0.9999), and the sample recovery rate was 97.02%-103.08%. This method was successfully applied for simultaneous determination of seven components in 7 batches of G. veitchiorum samples by HPLC-UV method. The method established in this study is simple and reliable, capable of qualitatively and quantitatively analyzing the main chemical components of G. veitchiorum, and is applicable to its quality evaluation.

Objective To explore the chain mediating effect of interpersonal promotion and calling on work autonomy and work engagement of medical staff.Methods From June to July 2023,a total of 310 medical staff from 5 tertiary public hos-pitals in Hangzhou were selected by convenience sampling.The questionnaire included work autonomy scale,interpersonal promo-tion scale,calling scale and work engagement scale for accurate and effective investigation,and data analysis was conducted using SPSS2 6.0 and AMOS 26.0.Results A total of 310 questionnaires were distributed and 257 were recovered with a recovery rate of 82.90％.There were statistically significant differences in work engagement among medical staff with different ages,marital status,working time,titles and positions(all P＜0.05).Calling partially mediated the effect of work autonomy on work engage-ment(95％CI[0.090,0.291],P＜0.001),and interpersonal promotion and calling played a partially chain mediating role be-tween work autonomy and work engagement(95％CI[0.016,0.103],P＜0.001).Conclusion Interpersonal promotion and calling play a partially chain mediating role between work autonomy and work engagement of medical staff.Work autonomy of medical staff not only has an indirect effect on work engagement through the mediating role of calling,but also enhances calling through interpersonal promotion and ultimately affects work engagement.

Objective:To discuss the regulatory effect of berberine(BBR)on fatty acids in the human glioma T98G cells and its effect on the cell proliferation,migration,and invasion,and to clarify its potential mechanism.Methods:The T98G cells at logarithmic growth phase were divided into control group and different concentrations(25,50,and 100 mg·L-1)of BBR groups.Cell wound healing assay was used to detect the migration rates of the cells in various groups;Transwell chamber assay was used to detect the invasion rates of the cells in various groups.The T98G cells at logarithmic growth phase were divided into control group and 100 mg·L-1 BBR group,and Mass spectrometry was used to detect the fatty acid contents in the cells in two groups.The T98G cells at logarithmic growth phase were divided into control group and different concentrations(50,100,and 150 mg·L-1)of BBR groups;Western blotting method was used to detect the expression levels of phosphatidylinositol 3-kinase(PI3K),phosphorylated PI3K(p-PI3K),protein kinase B(AKT),phosphorylated AKT(p-AKT),sterol regulatory element-binding protein 1(SREBP-1),and fatty acid synthase(FASN)in the cells in various groups.The expression of FASN was suppressed by gene silencing technology,and the T98G cells at logarithmic growth phase were divided into control group,shFASN1 group,and shFASN2 group.Western blotting method was used to detect the expression levels of FASN protein in the cells in various groups;clone formation assay was used to detect the clone formation of the cells in various groups;cell wound healing assay was used to detect the migration rates of the cells in various groups.Results:Compared with control group,the migration rates and invasion rates of the cells in different concentrations of BBR groups were decreased in a concentration-dependent manner(P<0.01),and the fatty acid content in the cells in 100 mg·L-1 BBR group was significantly decreased(P<0.01).Compared with control group,the expression levels of p-PI3K,p-AKT,SREBP-1,and FASN proteins in the cells in 150 mg·L-1 BBR group were significantly decreased(P<0.05 or P<0.01),and the expression level of SREBP-1 protein in the cells in 100 and 150 mg·L-1 BBR groups were significantly decreased(P<0.01).After suppression of FASN expression,compared with control group,the expression levels of FASN protein in the cells in shFASN1 and shFASN2 groups were significantly decreased(P<0.01),and the expression level of FASN protein in the cells in shFASN2 group was lower than that in shFASN1 group(P<0.05);compared with control group,the numbers of clone formation and migration rates of the cells in shFASN1 and shFASN2 groups were significantly decreased(P<0.01),and the migration rate of the cells in shFASN2 group was significantly lower than that in shFASN1 group(P<0.05).Conclusion:BBR interferes with fatty acid synthesis in the glioma T98G cells by reducing the expression of the PI3K/AKT/SREBP-1/FASN pathway related proteins,and decrease their migration and invasion capabilities.

ObjectiveTo present the exploration and application of a prospective follow-up research method for acute infectious disease surveillance based on natural community populations， using COVID-19 infection as an example， and to provide a reference for improving the infectious disease surveillance and early warning system. MethodsA multi-stage probability proportional sampling method was employed to sample residents from all communities of 16 administrative districts in Shanghai， with households as the units. A cohort for acute infectious diseases based on natural community populations was established. The baseline survey was conducted for all cohort subjects， and COVID-19 antigen test kits were distributed. From December 21， 2022 to September 30， 2023， prospective follow-up monitoring of COVID-19 antigen and nucleic acid was carried out on the study subjects on a weekly basis. The baseline characteristics and follow-up information of the cohort subjects were described. ResultsThe cohort for acute infectious diseases included a total of 12 881 subjects， comprising 6 098 males （47.3%） and 6 783 females （52.7%）. The baseline survey revealed that 35.2% （4 540/12 881） of the subjects had a history of COVID-19 infection. During the follow-up period from December 21， 2022 to September 30， 2023， the average incidence density in the cohort was 0.61/person-year， with a higher incidence density in females （0.63/person-year） compared to males （0.59/person-year）. Individuals aged 60 and above （0.64/person-year） and those with underlying health conditions （0.67/person-year） had a higher incidence density. Healthcare workers showed a notably higher incidence density （0.84/person-year） than that in other occupational groups. As of September 30， 2023， a total of 340 subjects in the cohort experienced secondary infections， with a median interval of 170 days between the first and second infections. ConclusionThis study applies cohort study method to acute infectious disease surveillance， providing crucial data support for estimating infection rates and forecasting alerts for acute infectious diseases in the community. This method can be promoted and applied as a new approach for acute infectious disease surveillance.
