Diabetes,a metabolic disease stemming from impaired or defective insulin secretion,ranks among the most severe chronic illnesses globally.While several approved drugs exist for its treatment,they often come with multiple side effects.Therefore,there is a pressing need for safe and effective anti-diabetic medications.Traditional Chinese medicine has recognized Lycium barbarum(LB;goji berry)plant,commonly known as"wolfberry fruit"in China,for over 2,000 years.Natural compounds derived from LB show promise in reducing diabetes levels.Although research on the impact of LB on diabetes is still limited,our review aims to explore the potential of LB in reducing the risk of diabetes and examine the underlying mechanisms involved.LB can modulate diabetes through various pathways,such as inhibitingα-amylase and α-glucosidase activities,promoting β-cell proliferation,stimulating insulin secretion,inhibiting glucagon secretion,improving insulin resistance and glucose tolerance,and enhancing anti-oxidant and anti-inflammatory activities.Additionally,LB improves gut flora and immunomodulation,further aiding diabetes management.These findings highlight the potential clinical utility of LB in managing diabetes and its complications within the framework of evidence-based modern medicine.

AIM:To evaluate the value of ultra-sound-guided erector spinae plane block(ESPB)combined with opioid-sparing anaesthesia in extra-corporeal shock wave lithotripsy(ESWL)for pancre-atic stones.METHODS:A total of 96 patients(60 males and 36 females,aged 20-65 years,ASA Ⅰ-Ⅱ,BMI 16-30 kg/m2)undergoing elective extracorpo-real shock wave lithotripsy for pancreatic duct stones were selected in our hospital from March 2022 to April 2023.The patients were randomly di-vided into conventional intravenous anesthesia group(group C,48 cases)and ESPB+opioid-sparing group(group E,48 cases).Patients in group C un-derwent general anesthesia with target-controlled infusion of propofol and remifentanil with sponta-neous breathing.Patients in group E underwent ul-trasound-guided bilateral ESPB before intravenous general anesthesia.The changes of hemodynamic indexes(HR,MAP)in the two groups were ob-served and recorded.The anesthetic effect,dosage of remifentanil,quality of anesthesia recovery,postoperative analgesic effect and incidence of perioperative adverse reactions(respiratory depres-sion,nausea and vomiting,pruritus,etc.)were ob-served in the two groups.RESULTS:Compared with group C,the incidence of intraoperative respiratory depression was significantly decreased,the intraop-erative consumption of remifentanil was de-creased,and the postoperative recovery time was shortened in group E(P＜0.05).The VAS scores of rest and cough pain and the incidence of postoper-ative nausea and vomiting were significantly de-creased in group E(P＜0.05).There was no signifi-cant difference in HR and MAP between the two groups(P＞0.05).CONCLUSION:Ultrasound-guided ESPB in ESWL for pancreatic duct stones is satisfac-tory and can save opioids with few complications.

Natural killer cells(NK)are important innate immune cells that do not require prior antigen exposure and can directly recognize and attack virus-infected cells and tumor cells.The activation and effector functions of NK cells are regulated by a balance of signals delivered through their surface activating receptors and inhibitory re-ceptors,which bind to ligands on target cells to achieve cytotoxicity via"induced self"and"missing self"recogni-tion models.The killing mechanisms of NK cells primarily include release of cytotoxic granules such as perforin and granzymes to induce target cell lysis,death receptor-mediated apoptosis,secretion of various cytokines,chemokines and growth factors to coordinate with other immune cells in killing tumor cells,thereby generating secondary im-mune responses and antibody-dependent cellular cytotoxicity(ADCC).

Objective To investigate the correlations of serum stromal cell-derived factor-1(SDF-1),chemokine receptor 7(CXCR7)and vascular density in the optic disc area with clinical stages in patients with normal-tension glaucoma(NTG).Methods A total of 157 patients with NTG were included in the NTG group and divided into stage Ⅰ group(n=29),stage Ⅱ group(n=88),and stage Ⅲ group(n=40)based on different clinical stages;additionally,56 healthy individuals with physical examinations in the same period were selected as control group.Serum SDF-1 and CXCR7 levels were compared between the NTG group and the control group;changes in vascular den-sity in the optic disc area among patients with different clinical stages were analyzed;the multivariate Logistic regression analysis was conducted to explore the risk factors for NTG.Results Compared with the control group,the NTG group had significantly increased serum levels of SDF-1 and CXCR7(P＜0.05).Compared with the control group,patients in the NTG group showed significantly decreased densities of large vessels,capillaries,and the entire area,as well as significantly increased density of avascular areas(P＜0.05).The densities of capillaries and the entire area were significantly lower in the stage Ⅱ group and stage Ⅲ group than the stage Ⅰ group,while the density of avascu-lar areas was significantly higher(P＜0.05).The densities of large vessels(r=-0.503,P=0.006),capillaries(r=-0.546,P＜0.001),and the entire area(r=-0.553,P＜0.001)were negatively significantly correlated with clinical stages,while the density of avascular area was positively significantly correlated with clinical stages(r=0.521,P=0.002).The proportions of patients with hypertension,history of alcohol consumption,family history of glaucoma,and high ser-um levels of SDF-1 and CXCR7 in the NTG group were significantly higher than those in the control group(P＜0.05).Multivariate Logistic regression analysis revealed that hypertension,family histo-ry of glaucoma,history of alcohol consumption,and high serum levels of SDF-1 and CXCR7 were risk factors for NTG(P＜0.05).Conclusion Patients with NTG have significantly increased ser-um levels of SDF-1 and CXCR7.The densities of large vessels,capillaries,and the entire area are negatively correlated with clinical stages,while the density of avascular areas is positively correlated with clinical stages.Serum levels of SDF-1 and CXCR7 can serve as effective reference indicators for the diagnosis and clinical staging of NTG.

The operation time was 60.0-150.0 min, intraoperative blood loss was 5-10 mL, pain score on the 3rd day after surgery was 0 points, and postoperative hospital stay was 2-3 days. All patients achieved complete resection of the masses and thymus without perioperative complications. Conclusion The tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device technique optimizes surgical visualization and instrument maneuverability while avoiding complications related to conventional anesthesia and tubing, thereby markedly enhancing the minimally invasive profile of anterior mediastinal masses resections. In addition to maintaining procedural safety, this approach effectively reduces postoperative pain and accelerates patient recovery, highlighting its potential for widespread clinical adoption.

Objective:To investigate the effects of psychological state on the setup errors of radiotherapy for breast cancer patients.Methods:A prospective cohort study was conducted. A total of 193 breast cancer patients in Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College from October 2022 to May 2023 were selected. Radiotherapy was performed after fixation with an integrated multi-functional device for the head, chest and abdomen. Psychological status of patients was assessed by using 9-item health questionnaire (PHQ-9) and generalized anxiety disorder 7 self-rating scale (GAD-7) before first radiotherapy, the 10th radiotherapy and the last radiotherapy. Based on the results of the questionnaires, patients were divided into psychological problem (anxiety or depression) group and non-psychological problem group. The general data and setup errors of radiotherapy in both groups were compared.Results:All the 193 patients were female, with a median age of 47 years. There were 53 patients in psychological problem group and they underwent a total of 507 image-guided procedures, with setup errors [ M ( Q1, Q3)] of 0.18 (0.07, 0.33), 0.20 (0.10, 0.33) and 0.19 (0.09, 0.30) in the left-right (X), superior-inferior (Y), and anterior-posterior (Z) directions, respectively; the remaining 140 patients in non-psychological problem group underwent 1 240 image-guided procedures, with setup errors [ M ( Q1, Q3)]of 0.17 (0.08, 0.30), 0.20 (0.10, 0.30) and 0.18 (0.09, 0.28) in the X, Y, and Z directions, respectively, and the differences were statistically significant ( Z values were -3.78, -2.00; P < 0.001, P = 0.046). Conclusions:Anxiety and depression have an influence on the setup errors of radiotherapy in patients with breast cancer. In the processs of radiotherapy for breast cancer, it is important to pay attention to the psychological status of patients.

Artificial intelligence (AI) technologies are being widely applied in radiotherapy. However, the integration of AI into clinical workflows of radiotherapy faces a series of challenges, such as poor model interpretability, domain shifts between clinical application and training data, and the inherent model uncertainties. Therefore, case-specific quality assurance (QA) is essential before deploying AI models in clinical practice. This paper reviews and summarizes QA methodologies for the application of AI models in radiotherapy across four key areas: image registration, image generation, region of interest segmentation, and treatment planning.

Objective:To evaluate the feasibility of using the domestic ArcherQA system for fast and simplified independent verification of CyberKnife (CK) stereotactic radiotherapy (SRT) plans.Methods:SRT plans of 57 patients treated with CK at Tianjin Medical University Cancer Institute and Hospital from August 2021 to August 2022 were retrospectively analyzed, including 15 intracranial, 30 pulmonary, and 12 abdominal tumors cases. Point-dose and planar-dose verifications were performed using an ionization chamber and radiochromic films embedded in a homogeneous phantom, and the results were compared with those calculated by the treatment planning system (TPS). The localization CT images and corresponding SRT plans were imported into the ArcherQA system for independent dose verification and analysis. The correlation between ArcherQA results and phantom measurements was analyzed, with comparisons of target mean dose differences and γ pass rates.Results:Phantom measurement results showed, the measured point-dose differences for intracranial, lung, and abdominal plans were -0.94% ± 3.22%, 1.92% ± 2.05%, and 2.12% ± 0.77%, respectively. The mean dose differences in target dose calculation between ArcherQA and TPS: intracranial in the gross tumor volume (GTV) regions were 0.34% ± 2.21%, lung tumor GTV were -2.47% ± 2.46%, and abdominal tumor GTV were 0.80% ± 2.61%, respectively. Among them, the abdominal GTV region showed the highest correlation between ArcherQA and measured results ( r=0.78). The average two-dimensional γ pass rates (2 mm/2%, threshold=10%) measured using phantom films were 95.92% ± 2.35% for intracranial, 95.70% ± 2.74% for lung, and 96.74% ± 3.41% for abdominal tumors plans, respectively. The three-dimensional ArcherQA results showed comparable γ pass rates (1 mm/2%, threshold=10%) for lung and abdominal GTV and PTV regions, with similar medians and data dispersion to film measurements. Conclusions:The ArcherQA system enables rapid and efficient independent dose verification of CK SRT plans without the need for additional hardware. The verification results show good correlation with phantom measurements, supporting its potential as an auxiliary quality assurance tool in clinical CK SRT implementation.

This study investigated international standard systems for radiotherapy, focusing on the comparison of the radiation protection standards for medical linear accelerators adopted in China, the UK, and the USA. Despite some specific differences, the standards for radiotherapy rooms in the three countries generally adhere to the basic principles set by the International Commission on Radiological Protection (ICRP) and the International Atomic Energy Agency (IAEA). Regarding the zoning principle of radiotherapy rooms, the definitions of the controlled areas are similar in China, the UK, and the USA, while the classification of areas beyond the controlled areas differs across the three countries. In terms of measurement conditions, all the three countries require measurements under the maximum output dose of the radiotherapy equipment, with only minor differences in details. For dose limits and compliance criteria for radiation shielding of radiotherapy rooms, China adopts the highest instantaneous dose rate as the control threshold. In contrast, the UK and the USA base their standards on dose limits evaluated over certain time intervals (annual, weekly, and daily), assessing compliance through workload calculation. In terms of method for deducing and calculating effective dose limits, UK standards stipulate that annual personnel exposure should be calculated using instantaneous dose rates. In comparison, the USA provides specific method for calculating dose rates per week and any one hour from instantaneous dose rates. The comparative analysis indicates that China′s method, which is based on the maximum instantaneous dose rates, may lead to increased construction costs of radiotherapy rooms under the same conditions, hindering the application and development of novel radiotherapy technologies. To address these concerns while maintaining radiation safety, it is recommended that China consider introducing method based on average instantaneous dose rates or calculating the annual personnel exposure doses. This will help optimize protection standards and advance radiotherapy technology.
