OBJECTIVE To optimize the extraction process of standard decoction of Longan seed. METHODS The amount of water added， extraction time and extraction times as the influencing factors， using the extract yield， gallic acid content， corilagin content， ellagic acid content， half clearance concentration （IC50） of 1，1-diphenyl-2-picryl-hydrazyl （DPPH） free radical and IC50 of 2，2′-azino-bis （3-ethylbenzothiazoline-6-sulfonic acid） ammonium salt （ABTS） free radical as the evaluation indexes， the analytic hierarchy process （AHP）， criteria importarue though inter-criteria correlation （CRITIC） and AHP-CRITIC method were used to calculate the weight values of each index； the extraction process of Longan seed standard decoction was optimized by single factor test combined with orthogonal experiment； validation test was also performed. RESULTS According to the AHP-CRITIC method， the weights of the above indicators were determined to be 9.224%， 11.784%， 19.320%， 11.206%， 20.597%， 27.869%， respectively. The best process of standard decoction of longan seed was to add 14 times water for the first extraction and extract for 30 minutes； and 12 times water for the second and third extractions， and extract for 20 minutes. Average comprehensive score of the 3 times validation experiments was 97.96 and the RSD was 0.97% （n＝3）. CONCLUSIONS The process is simple to operate， stable and feasible， which can provide a experimental basis for the further development and utilization of standard decoction of longan seed.

ObjectiveTo investigate the influencing factors for traditional Chinese medicine （TCM） syndromes in pancreatic cancer by analyzing 608 cases， and to provide a theoretical reference for TCM syndrome differentiation and standardized treatment of pancreatic cancer. MethodsA total of 608 patients with a pathological or clinical diagnosis of pancreatic cancer who were admitted to Shanxi Institute of Traditional Chinese Medicine， The Affiliated Hospital of Shanxi University of Chinese Medicine， and Shanxi Provincial Hospital of Integrated Traditional Chinese and Western Medicine from January 2019 to December 2023 were enrolled， and TCM syndrome differentiation was performed. The chi-square test was used for comparison of categorical data between groups. The clinical data with statistical significance between groups were included in the regression analysis， and the unordered polytomous logistic regression model was used to investigate the influencing factors for the TCM syndrome of pancreatic cancer.

ConclusionSex， course of the disease， clinical stage， presence or absence of lymph node metastasis， surgery， chemotherapy， radiotherapy， and immunotherapy are the main influencing factors for the TCM syndrome of pancreatic cancer.

Objective To evaluate the surgical efficacy of unilateral pneumonectomy for the treatment of tuberculous destroyed lung, analyze the causes of severe postoperative complications, and explore clinical management strategies. Methods A retrospective analysis was conducted on the clinical data of patients with tuberculous destroyed lung who underwent unilateral pneumonectomy at the Public Health Clinical Center of Chengdu from 2017 to 2023. Postoperative severe complications were statistically analyzed. Patients were divided into a non-severe complication group and a severe-complication group, and the causes, management, and outcomes of complications were analyzed. Results A total of 134 patients were included, comprising 69 males and 65 females, with a mean age of 17-73 (40.43±12.69) years. There were 93 patients undergoing left pneumonectomy and 41 patients undergoing right pneumonectomy. Preoperative sputum smear was positive in 35 patients, all of which converted to negative postoperatively. There were 58 patients with hemoptysis preoperatively, and none experienced hemoptysis postoperatively. Postoperative incisional infection occurred in 8 (5.97%) patients, and postoperative pulmonary infection in 26 (19.40%) patients. Severe postoperative complications occurred in 17 (12.69%) patients, including empyema in 9 (6.72%) patients, bronchopleural fistula with empyema in 1 (0.75%) patient, severe pneumonia in 3 (2.24%) patients, postpneumonectomy syndrome in 1 (0.75%) patient, chylothorax in 1 (0.75%) patient, ketoacidosis in 1 (0.75%) patient, and heart failure with severe pneumonia in 1 (0.75%) patient. Perioperative mortality occurred in 2 (1.49%) patients, both of whom underwent right pneumonectomy. Multivariate logistic regression analysis revealed that a history of ipsilateral thoracic surgery, concomitant Aspergillus infection, and greater blood loss were independent risk factors for severe complications following unilateral pneumonectomy for tuberculous destroyed lung (P<0.05). Conclusion Unilateral pneumonectomy for patients with tuberculous destroyed lung can significantly improve the clinical cure rate, sputum conversion rate, and hemoptysis cessation rate. However, there is a certain risk of severe perioperative complications and mortality, requiring thorough perioperative management and appropriate management of postoperative complications.

OBJECTIVE To evaluate the efficacy， safety and cost-effectiveness of toripalimab （Tor） combined with chemotherapy （CT） in the treatment of locally advanced or metastatic non-small cell lung cancer （NSCLC）. METHODS PubMed， the Cochrane Library， Embase， Web of Science， CBM， CNKI， Wanfang Data， and Health Technology Assessment （HTA） related websites were searched to collect the HTA reports， systematic reviews/meta-analyses and pharmacoeconomic studies of Tor+CT in the treatment of locally advanced or metastatic NSCLC from database/website inception to March 31， 2025. After data extraction and quality evaluation， the results of the included studies were analyzed descriptively. RESULTS A total of eleven studies were included， involving five systematic reviews/meta-analyses， and six pharmacoeconomic studies. Among the five systematic reviews/ meta-analyses， two were of high quality， while there was one each of moderate， low， and very low quality. All six pharmacoeconomic studies were of good quality. In terms of efficacy， compared with CT， Tor+CT significantly improved patients’ progression-free survival （PFS） and overall survival （P＜0.05）. In addition， compared with ipilimumab+CT， durvalumab， durvalumab+tremelimumab and sugemalimab+CT， Tor+CT could also improve the PFS （P＜0.05）. In terms of safety， there was no significant difference in the incidence of grade≥3 adverse events between patients receiving Tor+CT and CT （P＞0.05）； while Tor+CT had a lower incidence of grade≥3 adverse E-mail： events， compared with camrelizumab+CT， pembrolizumab+ 3233255290@qq.com ipilimumab， nivolumab+CT and atezolizumab+CT （P＜0.05）.In terms of cost-effectiveness， Tor+CT treatment had certain cost-effectiveness advantages， compared with CT. CONCLUSIONS Compared with CT， other programmed death-1/programmed death-ligand 1 inhibitors alone， or their combination with CT， Tor+CT for the treatment of locally advanced or metastatic NSCLC has good efficacy， safety and cost-effectiveness.

The rapid emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants that evade immunity elicited by vaccination has posed a global challenge to the control of the coronavirus disease 2019 (COVID-19) pandemic. Therefore, developing countermeasures that broadly protect against SARS-CoV-2 and related sarbecoviruses is essential. Herein, we have developed a lipid nanoparticle (LNP)-encapsulated mRNA (mRNA-LNP) encoding the full-length Spike (S) glycoprotein of SARS-CoV-2 (termed RG001), which confers complete protection in a non-human primate model. Intramuscular immunization of two doses of RG001 in Rhesus monkey elicited robust neutralizing antibodies and cellular response against SARS-CoV-2 variants, resulting in significantly protected SARS-CoV-2-infected animals from acute lung lesions and complete inhibition of viral replication in all animals immunized with low or high doses of RG001. More importantly, the third dose of RG001 vaccination elicited effective neutralizing antibodies against current epidemic XBB and JN.1 strains and similar cellular response against SARS-CoV-2 Omicron variants (BA.1, XBB.1.16, and JN.1) were observed in immunized mice. All these results together strongly support the great potential of RG001 in preventing the infection of SARS-CoV-2 variants of concern (VOCs).

Soil cadmium pollution can adversely affect the cultivation of the ornamental plant, Coleus scutellarioides. Upon cadmium contamination of the soil, the growth of C. scutellarioides is impeded, and it may even succumb to the toxic accumulation of cadmium. In this study, we investigated the effects of arbuscular mycorrhizal fungi (AMF) on the adaptation of C. scutellarioides to cadmium stress, by measuring the physiological metabolism and the degree of root damage of C. scutellarioides, with Aspergillus oryzae as the test fungi. The results indicated that cadmium stress increased the activity of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT), and the content of malondialdehyde (MDA) and proline (Pro) within the cells of C. scutellarioides, but inhibited mycorrhizal infestation rate, root vigour and growth rate to a great degree. With the same cadmium concentration, the inoculation of AMF significantly improved the physiological indexes of C. scutellarioides. The maximum decrease of MDA content was 42.16%, and the content of secondary metabolites rosemarinic acid and anthocyanosides could be increased by up to 27.43% and 25.72%, respectively. Meanwhile, the increase of root vigour was as high as 35.35%, and the DNA damage of the root system was obviously repaired. In conclusion, the inoculation of AMF can promote the accumulation of secondary metabolites, alleviate root damage, and enhance the tolerance to cadmium stress in C. scutellarioides.

Hepatocellular carcinoma(HCC)is one of the cancers with the highest incidence and mortality rates in China and often presents with insidious early clinical manifestations.This frequency results in the majority of patients being diagnosed at middle and advanced stage of the disease,thereby missing the opportunity for potentially curative surgical interventions.For patients who are ineligible for radical surgical resection,a variety of therapeutic approaches,including systemic antitumor therapy,local radiotherapy,interventional treatment,and liver transplantation,have been employed.Moreover,neoadjuvant therapies have transformed a subset of initially unresectable HCC cases into operable ones.Nevertheless,many patients fail to benefit from these treatments,underscoring the urgent need for novel therapeutic targets.Cancer-associated fibroblasts(CAFs),a principal component of the solid tumor microenvironment,play a pivotal role in the proliferation,migration,invasion,and treatment resistance of cancer cells.This review delineates the origins of CAFs and their mechanisms of action in the pathogenesis and progression of HCC and discusses potential therapeutic strategies targeting CAFs.

With the advent of an aging society,Alzheimer's disease(AD)has gradually become a major ailment affecting the elderly.AD is a neurodegenerative disorder associated with cognitive impairments.In AD patients,brain network connections are disrupted,and their topological properties are also affected,leading to the disintegration of anatomical and functional connections.Anatomical connections can be tracked and evaluated using structural magnetic imaging(MRI)and diffusion tensor imaging(DTI),while functional connections are detected through functional MRI to assess their connectivity status.This review incorporates the findings of previous scholars and summarizes the current research of AD.It mainly discusses the imaging characteristics of large-scale brain network changes in AD patients,so as to provide researchers with scientific and objective imaging markers for AD prediction and early diagnosis,as well as future research.

OBJECTIVE To evaluate the therapeutic effects of Fuzheng jiedu therapy of traditional Chinese medicine （TCM） in the treatment of advanced non-small cell lung cancer （NSCLC）. METHODS Randomized controlled trials on the treatment of NSCLC with Fuzheng jiedu therapy of TCM+conventional chemotherapy （trial group） versus conventional chemotherapy （control group） were collected by searching PubMed， CBM， China Periodicals Full Text Database， VIP and Wanfang data service platform during the inception-Oct.Two researchers respectively screened the literature and extracted data， evaluated the quality according to Cochrane 5.4 tool， and used RevMan 5.3 software to perform meta-analysis on the data. RESULTS Nineteen pieces of literature were finally included in the study； meta-analysis showed disease control rate [RR＝1.15， 95%CI （1.07， 1.23）， P＝ 0.000 1]， objective remission rate [RR＝1.47， 95%CI （1.29， 1.67）， P＜0.000 01]， Karnofsky performance scores [WMD＝6.11， 95%CI （2.97， 9.25）， P＝0.000 1]， the levels of immune function indexes （CD3+， CD4+， CD4+/CD8+）， inflammatory factor indicators [interleukin-2 （IL-2）， interferon-γ （IFN-γ）] and lung function indexes （forced vital capacity， forced expiratory volume in the first second and peak expiratory flow） in the trial group were higher than control group （P＜0.05）. The symptomatic score [WMD＝－2.83， 95%CI （－4.42， －1.24）， P＝0.000 5]， the levels of IL-6 [WMD＝－11.20， 95%CI （－21.75，－0.64）， P＝ 0.04]， and the incidence of ADRs （myelosuppression， hepatic and renal injury， gastrointestinal reactions in trial group were all lower than control group （P＜0.05）. In addition， the levels of natural killer cells in the trial group were higher than the control group， but the results were not statistically significant （P＞0.05）. CONCLUSIONS Compared with conventional chemotherapy， Fuzheng jiedu therapy of TCM combined with conventional chemotherapy has obvious advantages in increasing the disease control rate and objective remission rate， improving the quality of life， promoting TCM syndrome and inflammatory status，enhancing immunity and lung function， and decreasing the incidence of ADRs in NSCLC patients.

Background The staff in centers for disease control and prevention (CDC) were at a great risk for psychological distress when they were faced with outbreak-related prevention and control work and routine tasks during the COVID-19 period. Psychological resilience and burnout are two key influencing factors on psychological distress. Objective To explore the status and mechanisms of psychological resilience, burnout, and psychological distress among CDC staff. Methods From September to October 2022, a cross-sectional survey was conducted in all CDC staff in Beijing, and 2228 CDC staff from 17 units (including 1 municipality-level CDC and 16 district-level CDCs) participated the questionnaire survey. The basic information questionnaire, Connor-Davidson Resilience Scale (CD-RISC-10) Chinese version, Maslach Burnout Inventory-General Survey (MBI-GS) Chinese version, and the 10-item Kessler Psychological Distress Scale (Kessler10) Chinese version were selected in our study. Mann-Whitney U test or Kruskal-Wallis H test was used to analyze the differences in the scores of psychological resilience, burnout, and psychological distress by demographic and sociological characteristics. The correlations among the three elements were analyzed by Spearman correlation analysis. Potential influencing factors of psychological distress of the CDC staff were evaluated by multiple linear regression. A potential mediating effect of psychological resilience-burnout-psychological distress was analyzed by the mediation package of R 4.2.0, and validated by Bootstrap method. Results Of 2228 questionnaires distributed, 2022 valid questionnaires were collected, and the recovery rate was 90.75%. The median (P₂₅, P₇₅) psychological distress score of CDC staff was 13.00 (8.00, 24.00), and the number of participants with psychological distress levels of 1, 2, 3, and 4 was 358 (17.71%), 546 (27.00%), 362 (17.90%), and 756 (37.39%), respectively. The median (P₂₅, P₇₅) psychological resilience score was 24.00 (20.00, 30.00) and the median (P₂₅, P₇₅) burnout score was 38.00 (25.00, 50.00). The results of the multiple linear regression showed that psychological resilience, burnout, caring for the elderly, having a chronic disease, and monthly income had independent influences on psychological distress (P<0.05), and emotional exhaustion, cynicism, and reduced personal accomplishment (reversed) in the case of burnout had a great effect on psychological distress (P<0.05). After controlling general demographic characteristic variables, total burnout score exerted a partial mediation effect on the relationship between psychological resilience and psychological distress, with a mediation effect value of −0.439 (95%CI: −0.483, −0.397), and a total mediation effect contribution rate of 60.89%. The two dimensions of burnout (emotional exhaustion and cynicism) played a partial mediating role between psychological resilience and psychological distress, with mediating effect contribution rates of 42.44% and 41.41%, respectively. Conclusion Psychological distress among CDC staff in Beijing was prominent during COVID-19. Psychological resilience can act directly on psychological distress or indirectly on psychological distress through burnout. Both emotional exhaustion and cynicism dimensions of burnout have a partial mediating role between psychological resilience and psychological distress. Increasing psychological resilience and decreasing burnout may reduce the occurrence of psychological distress.
