CD8+T cell-based immune-therapeutics,including immune checkpoint inhibitors and adoptive cell therapies(tumor-infiltrating lymphocytes(TILs),T cell receptor-engineered T cells(TCR-T),chimeric antigen receptor T cells(CAR-T)),have achieved significant successes and prolonged patient survival to varying extents and even achieved cure in some cases.However,immunotherapy resistance and tumor insusceptibility frequently occur,leading to treatment failure.Recent evidences have highlighted the ponderance of tumor cells metabolic reprogramming in establishing an immunosuppressive milieu through the secretion of harmful metabolites,immune-inhibitory cytokines,and alteration of gene expression,which suppress the activity of immune cells,particularly CD8+T cells to evade immune surveillance.Therefore,targeting tumor cell metabolic adaptations to reshape the immune microenvi-ronment holds promise as an immunomodulatory strategy to facilitate immunotherapy.Here,we summarize recent advances in the crosstalk between immunotherapy and tumor reprogramming,focusing on the regulatory mechanisms underlying tumor cell glucose metabolism,amino acid meta-bolism,and lipid metabolism in influencing CD8+T cells to provide promising metabolic targets or combinational strategies for immunotherapy.

Acute Gelsemium poisoning is a systemic disease primarily affecting the central nervous system and respiratory symptoms caused by the ingestion of a substantial amount of Gelsemium within a short period. It manifests as sudden onset and rapid progression, primarily caused by accidental ingestion due to misidentification, and posing significant health risks. The compilation of the Technical Plan for Emergency Health Response to Acute Gelsemium Poisoning describes in detail the specialized practice and technical requirements in the process of handling acute Gelsemium poisoning, including accident investigation and management, laboratory testing and identification, in-hospital treatment, and health monitoring. The guidelines clarify key procedures and requirements such as personal protection, investigation elements, etiology determination, medical rescue, and health education. The key to acute Gelsemium poisoning investigation lies in promptly identifying the toxin through exposure history, clinical manifestations, and sample testing. Because there is no specific antidote for Gelsemium poisoning, immediate removal from exposure, rapid elimination of the toxin, and respiratory monitoring are critical on-site rescue measures. Visual identification of food or herbal materials, followed by laboratory testing to determine Gelsemium alkaloids in samples is a rapid effective screening method. These guidelines offer a scientific, objective, and practical framework to support effective emergency responses to acute Gelsemium poisoning incidences.

Objective:To explore the effects of vitamin D supplementation combined with suspended lumbar abdominal muscle training on rehabilitation and bone metabolism indexes of patients after OVCF.Methods:A total of 140 patients with osteoporotic vertebral compression fractures (OVCF) treated at Yantaishan Hospital from Jun. 2021 to Jun. 2024 were included in this study. Patients were randomly assigned to a control group and an observation group using a random number table, with 70 patients in each group. The control group received suspension lumbar and abdominal muscle training, while the observation group received vitamin D supplementation combined with suspension lumbar and abdominal muscle training. Outcomes evaluated included VAS scores, Oswestry Disability Index (ODI) , Cobb Angle, lumboabdominal muscle strength, and serum levels of 25-hydroxyvitamin D [25 (OH) D], bone mineral density T value, and bone metabolism markers [serum osteocalcin (OC) , calcitonin (CT) , total type I collagen amino-terminal propeptide (tPINP) , type I collagen carboxy-terminal peptide β special sequence (β-CTX) , intact parathyroid hormone (iPTH) , and bone-specific alkaline phosphatase (BALP) ] measured by chemiluminescence.Results:In comparison with the control group, the VAS and ODI scores in the observation group were lower after treatment ( t=13.66, t=9.87, P < 0.05) . Compared to the control group, the lumbar muscle strength score of the observation group, the 25 (OH) D level and bone mineral density T value was higher after treatment ( t=57.63, t=6.64, t=5.01, P < 0.05) , and the Cobb Angle was smaller ( t=9.21, P < 0.05) .Compared with the control group, the bone metabolism indexes OC, CT, tPINP, and BALP were higher in the observation group after treatment ( t=4.21, t=3.05, t=2.66, t=3.16, P < 0.05) , while the iPTH and β-CTX were lower ( t=7.28, t=3.50, P < 0.05) . Conclusions:Vitamin D supplementation combined with suspended lumbar and abdominal muscle training can promote postoperative rehabilitation of OVCF patients and improve the level of bone metabolism indexes after surgery.

OBJECTIVES: Major depressive disorder (MDD) patients with anhedonia tend to have a poor prognosis. The underlying imaging basis for anhedonia in MDD remains largely unknown. The relationship between nodal properties and anhedonia in MDD patients need to be further investigated. Herein, this study aims to explore differences of cerebral functional node characteristics in MDD patients with severe anhedonia (MDD-SA) and MDD patients with mild anhedonia (MDD-MA) before and after the antidepressant treatment. METHODS: Ninety participants with current MDD were recruited in this study. 24-Item Hamilton Depression Scale (HAMD-24) and Snaith-Hamilton Pleasure Scale (SHAPS) were used to assess the severity of depression and anhedonia at baseline and the end of 6-months treatment. The MDD patients who scored above the 25th percentile on the SHAPS were assigned to an MDD-SA group (n=19), while those who scored below the 25th percentile were assigned to an MDD-MA group (n=18). All patients in the 2 groups received antidepressant treatment. Functional magnetic resonance imaging (fMRI) images of all the patients were collected at baseline and the end of 6-months treatment. Graph theory was applied to analyze the patients' cerebral functional nodal characteristics, which were measured by efficiency (e_i) and degree (k_i). RESULTS: Repeated measures 2-factor ANCOVA showed significant main effects on group on the e_i and k_i values of left superior frontal gyrus (LSFG) (P=0.003 and P=0.008, respectively), and on the e_i and k_i values of left medial orbital-frontal gyrus (LMOFG) (P=0.004 and P=0.008, respectively). Compared with the MDD-MA group, the significantly higher e_i and k_i values of the LSFG (P=0.015 and P=0.021, respectively), and the significantly higher e_i and k_i values of the LMOFG (P=0.015 and P=0.037, respectively) were observed in the MDD-SA group at baseline. Meanwhile, higher SHAPS scores could result in higher e_i and k_i values of LSFG (P=0.019 and P=0.026, respectively), and higher e_i value of LMOFG (P=0.040) at baseline; higher SHAPS scores could result in higher e_i values of LSFG (P=0.049) at the end of 6-months treatment. The multiple linear regression analysis revealed that sex were negatively correlated with the e_i and k_i values of LSFG (r= -0.014, P=0.004; r=-1.153, P=0.001, respectively). The onset age of MDD was negatively correlated with the k_i value of LSFG (r=-0.420, P=0.034) at the end of 6-months treatment. We also found that SHAPS scores at baseline were positively correlated with the HAMD-24 scores (r=0.387, P=0.022) at the end of 6-months treatment. CONCLUSIONS There are obvious differences in nodal properties between the MDD-SA and the MDD-MA patients, such as the high e_i of LSFG in the MDD-SA patients, which may be associated with the severity of anhedonia. These nodal properties could be potential biomarkers for the prognosis of MDD. The increased e_i and k_i values in the LSFG of MDD-SA patients may underlie a compensatory mechanism or protective mechanism. The mechanism may be an important component of the pathological mechanism of MDD-SA. The poor prognosis in the MDD-SA patients suggests that anhedonia may predict a worse prognosis in MDD patients. Sex and onset age of MDD may affect the nodal properties of LSFG at baseline and the end of 6-months treatment.

The existing regulations and systems of the Swedish Medical Products Agency (MPA) have clear provisions on the definition, classification and listed on the market procecure of pharmaceutical products, and the supervision strictly follows the EU standards. Traditional Chinese Medicine (TCM) products belong to the category of Swedish Herbal Medicine Products (HMP) or Traditional Herbal Medicine Products (THMP) and are under the supervision of Swedish Pharmaceutical Products Administration (MPA). This paper analyzes the classification, relevant regulations and registration procecures of TCM products in Sweden. It is suggests that TCM enterprises should fully understand the EU regulations and guidance regulations before listed on the market of TCM products. They should also clarify the product category, and provide sufficient and accurate evidence. In the application process, they should pay attention to strengthening communication with the drug administration units of Sweden.

The Hedgehog (Hh) signalling pathway is essential for cellular proliferation and differentiation during embryonic development. Gain and loss of function of Hh signalling are known to result in an array of craniofacial malformations. To determine the critical period for Hh pathway antagonist-induced frontal bone hypoplasia, we examined patterns of dysmorphology caused by Hh signalling inhibition. Pregnant mice received a single oral administration of Hh signalling inhibitor GDC-0449 at 100 mg•kg or 150 mg•kg body weight at preselected time points between embryonic days (E)8.5 and 12.5. The optimal teratogenic concentration of GDC-0449 was determined to be 150 mg•kg. Exposure between E9.5 and E10.5 induced frontal bone dysplasia, micrognathia and limb defects, with administration at E10.5 producing the most pronounced effects. This model showed decreased ossification of the frontal bone with downregulation of Hh signalling. The osteoid thickness of the frontal bone was significantly reduced. The amount of neural crest-derived frontal bone primordium was reduced after GDC-0449 exposure owing to a decreased rate of cell proliferation and increased cell death.

Objective To explore the value of DWI and ADC in differential diagnosis of benign prostatic hyperplasia (BPH)and prostatic cancer(PCa).Methods The data of 43 patients with BPH or PCa proven by histopathology were retrospectively reviewed. There were 21 patients with PCa and 22 patients with BPH.All of the patients were examined by DWI at 1.5T MRI.On the DWI,signal intensities in ROI were measured at the b value of 800 s/mm2 and 1 600 s/mm2 ,respectively.On the ADC map,ADC values in ROI were measured.The differences of the ADC values and the signal intensities of DWI were compared between the benign BPH and the PCa by using independent sample tGtest.Diagnostic efficiency of the signal intensity and the ADC value for PCa were analyzed by using ROC curve.Results There were statistically significant differences of the ADC values and the signal intensities of DWI at the b value of 800 s/mm2 and 1 600 s/mm2 between the BPH and the PCa (P＜0.05).The ADC at the b value of 1 600 s/mm2 had the highest diagnostic efficiency,the DWI at the b value of 1 600 s/mm2 took a second place,and the DWI at the b value of 800 s/mm2 was worst.Conclusion DWI and ADC are helpful for the diagnosis of PCa,and ADC at b value of 600 s/mm2 has the highest diagnostic efficiency.
