Cancer immunotherapy has emerged as a promising strategy. However, low response rates and immune-related side effects have plagued immunotherapy. Metallic nanoparticles, utilizing metals as their framework, are gaining prominence in cancer immunotherapy. Metal ions have shown the ability to modulate immune status by activating the cGAS-STING pathway and inducing immunogenic cell death (ICD), thereby enabling multidimensional activation of immunotherapy. Metallic nanoparticles offer significant advantages in cancer immunotherapy, leading to their increasing use in enhancing therapeutic outcomes. In view of the ever-increasing research on metallic nanoparticles, this review presents the construction, characterization, and enhanced cancer immunotherapeutic effects of different types of metal nanosystems from the perspective of the immunoregulatory mechanisms of metal ions. We delve into the current limitations and future directions of metallic nanoparticles in this rapidly evolving field. To the best of our knowledge, this review offers the most up-to-date and systematic analysis of metallic nanoparticles in immunotherapeutic applications. It is anticipated that this review of metallic nanoparticles will inspire a more refined and intelligent design of metallic nanoparticles for future research, paving the way for advancing their clinical applications.

Objective:To investigate the influence of cognitive-behavior therapy on the psychological status of family members of terminal cancer patients. Method:A total of 60 families of terminal cancer patients were selected and randomly divided into observation group (30 cases) and control group (30 cases). The observation group was treated with cognitive-behavior therapy, while the control group was given general supportive psychological care. The Hamilton Depression Scale ( HAMD) , Hamilton Anxiety Scale ( HAMA) and Pittsburgh Sleep Quality Index ( PSQL) were used to evaluate the family members of the two groups of patients before and after the intervention. Results: Before the intervention, there was no statistical significance difference in the scores of HAMA, HAMD and PSQI between the two groups (P>0. 05). After the intervention, the scores of HAMA, HAMD and PSQI in the observation group were significantly lower than those before the intervention ( P <0 . 05 ); and the scores of HAMA, HAMD and PSQI in the observation group were significantly lower than those in the control group ( P<0 . 05 ) . Conclusion:Cognitive-behavior therapy can significantly improve the negative emotions of depression, anxiety and sleep disorder among family members of terminal tumor patients.

Objective To describe an intelligent three-dimensional technique for automatic visualization of the fetal cranial mid-sagittal view to allow for the differential diagnosis of fetal midline anomalies.Methods Two hundred and twenty pregnant women with singleton pregnancies were imaged to display the mid-sagittal view of fetal head using a new 3D program (Smart MSP) developed by our team.Results The mid-sagittal view of the fetal head was successfully visualized in 190 normal cases (95％) and 18 abnormal cases (90％) by Smart MSP program.The total successful rate was 94.5％ (208/220).Conclusions Smart MSP is a novel and feasible method for the automatic visualization of fetal cranial midsagittal plane and may become a potential tool for routinely screening the fetal midline anomalies.

In order to improve the interfacial bonding strength of hydroxyapatite/polyurethane implanted material and dispersion of hydroxyapatite in the polyurethane matrix, we in the present study synthesized nano-hydroxyapatite/polyurethane composites by in situ polymerization. We then characterized and analyzed the fracture morphology, thermal stability, glass transition temperature and mechanical properties. We seeded MG63 cells on composites to evaluate the cytocompatibility of the composites. In situ polymerization could improve the interfacial bonding strength, ameliorate dispersion of hydroxyapatite in the properties of the composites. After adding 20 wt% hydroxyapatite into the polyurethane, the thermal stability was improved and the glass transition temperatures were increased. The tensile strength and maximum elongation were 6.83 MPa and 861.17%, respectively. Compared with those of pure polyurethane the tensile strength and maximum elongation increased by 236.45% and 143.30%, respectively. The composites were helpful for cell adhesion and proliferation in cultivation.

Objective To explore the Chinese massage therapy for the treatment of infantile anorexia of spleen and stomach type clinical curative effect.Methods 2 to 6 years old anorexia children treated from September 2010 to September 2012 for general treatment and health care in our hospital were randomly recruited into a Qi deficiency of both spleen and stomach group and a Yin deficiency of both spleen and stomach group with 25 cases in each group.Both groups were treated with chiropractic therapy.On this basis,Qi deficiency of both spleen and stomach group was applied point-massage on Weishu,Pishu,and Zusanli; Yin deficiency of both spleen and stomach group was applied point-massage on Weishu,Ganshu,and Shenshu.Results ① The comparison of disease and syndromes:the total effective rate was 92％ (23/25)and 88％ (22/25) in Qi deficiency of both spleen and stomach group and Yin deficiency of both spleen and stomach group separately,showing no significant difference (x2=0.886,P＞0.05); the total symptoms improving rate was 92％(23/25) and 76％(19/25)in Qi deficiency of both spleen and stomach group and Yin deficiency of both spleen and stomach group separately,the difference showing statistically significant (x2=0.625,P＜0.05).② Symptom score comparison before and after treatment:The main symptoms score and accompanied symptoms score before and after the treatment were [(18.32±2.42) ％,(4.12±0.17) points] and [(16.80±3.77) ％,(5.30 ±0.41) points] in the Qi deficiency group and [(18.18±2.10),(4.45±0.30) points] and [(19.66 ± 3.62)％,(6.01 ± 1.02) points] in the Yin deficiency group.Both groups showed obvious improvements in the main and accompanied symptom scores after the treatment (P＜0.01),but no significant difference between the two groups (P＞0.05).Conclusion The treatment of anorexia due to deficiency of both spleen and stomch with chiropractic and point-massage was effective.
