Radiopharmaceuticals operate by combining radionuclides with carriers. The radiation energy emitted by radionuclides is utilized to selectively irradiate diseased tissues while minimizing damage to healthy tissues. In comparison to external beam radiation therapy, radionuclide drugs demonstrate research potential due to their biological targeting capabilities and reduced normal tissue toxicity. This article reviews the applications and research progress of radiopharmaceuticals in cancer treatment. Several key radionuclides are examined, including ²²³Ra, ⁹⁰Y, Lutetium-177 (¹⁷⁷Lu), ²¹²Pb, and Actinium-225 (²²⁵Ac). It also explores the current development trends of radiopharmaceuticals, encompassing the introduction of novel radionuclides, advancements in imaging technologies, integrated diagnosis and treatment approaches, and equipment-medication combinations. We review the progress in the development of new treatments, such as neutron capture therapy, proton therapy, and heavy ion therapy. Furthermore, we examine the challenges and breakthroughs associated with the clinical translation of radiopharmaceuticals and provide recommendations for the research and development of novel radionuclide drugs.

Objective:To investigate the relationships among coping styles,negative life events,meaning in life,and psychological resilience in adolescents.Methods:A total of 1 434 adolescents aged 13 to 17 years comple-ted online questionnaire survey.The Simplified Coping Style Questionnaire(SCSQ),Adolescent Self-Rating Life E-vents Checklist(ASLEC),Chinese Meaning in Life Questionnaire(C-MLQ),and Connor-Davidson resilience scale(CD-RISC)were used to assess coping styles,perceived impact of negative life events,experience and pursuit of meaning in life,and ability to cope with and adapt to adversity,respectively.Logistic regression was used to explore the associations among these variables.Results:A total of 723 students(50.4％)tended to adopt negative coping styles when facing adverse events.Positive coping styles were negatively associated with being in senior high school(OR=0.62,P＜0.05)and impact of life events(OR=0.97,P＜0.001),while positively associated with sense of meaning in life(OR=1.04,P＜0.001)and psychological resilience(OR=1.04,P＜0.001).Conclusion:Among adolescents,positive coping styles are inversely associated with impact of negative life events,and positively associ-ated with both the sense of life meaning and psychological resilience.

Depression and anxiety are the two most common mental disorders, which have severe negative impacts on individuals and society. Early and accurate identification of these disorders is crucial for symptom control and positive prognosis. Traditional identification approaches such as scale screening and interviews rely on patients' self-reporting and the comprehensive judgment of psychiatrists. These methods inherently have limitations such as subjectivity and dependence on the availability and convenience of medical resources. Therefore, seeking objective means to assist in the identification of depression and anxiety disorders has become a research focus in recent years. Electroencephalogram (EEG), which describes changes in potential difference on the scalp surface, offers advantages such as objectivity, quantification and high temporal resolution. EEG has become one of the potential objective indicators for identifying depression and anxiety disorders.Machine learning algorithms are key technologies for extracting EEG signal features and improving identification accuracy. The combination of EEG collection and machine learning algorithms is expected to become a new method for identifying depression and anxiety disorders. In addition, portable EEG collection provides the possibility for rapid identification of mental disorders and large-scale screening activities. This article reviews the application of EEG for depression and anxiety disorders identification, providing a reference for scholars in related fields, with the aim of promoting the development of mental disorder identification towards objectivity and visualization in China.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To determine the risk factors for development of combined hepatocellular-cholangiocarcinoma (CHC) and intrahepatic cholangiocarcinoma (ICC).Methods:The clinical data of patients with ICC or CHC confirmed by pathology at Henan Provincial People's Hospital from January 2012 to December 2018 were retrospectively analyzed. Of 225 patients with ICC or CHC, there were 90 males and 135 females, aged (58.7±10.4) years old. Based on the pathological type, there were 172 patients in the ICC group and 53 patients in the CHC group. The healthy control group was selected from 450 individuals who underwent routine health examination in the same hospital, and there were 189 males and 261 females, aged (56.7±9.3) years old. Univariate and multivariate logistic regression were used to analyze the risk factors of ICC and CHC.Results:The risk factors of ICC included hepatitis B surface antigen (HBsAg) (+ )/hepatitis B core antibody (anti-HBc) (+ ) ( OR=9.373, 95% CI: 4.784-18.363, P<0.001), hepatitis C virus antibody (HCV-Ab) (+ ) ( OR=7.151, 95% CI: 1.195-42.776, P=0.031), diabetes mellitus ( OR=3.118, 95% CI: 1.733-5.612, P<0.001) and hepatolithiasis ( OR=18.650, 95% CI: 5.210-66.767, P<0.001). The risk factors of CHC included HBsAg (+ )/anti-HBc(+ )( OR=54.891, 95% CI: 17.434-172.822, P<0.001) and HCV-Ab (+ ) ( OR=37.785, 95% CI: 5.720-249.611, P<0.001). Conclusion:HBV infection, HCV infection, hepatolithiasis, diabetes mellitus and cirrhosis were risk factors for ICC. HBV and HCV infection were risk factors of CHC.

Objective: To investigate the changes of ³¹P-MRS in denervated skeletal muscle at 7.0 T MR system. Methods: In the experiment group, a total of 18 male Sprague-Dawley rats aged 6-8 weeks old and weighing 200-250 g were obtained. The right posterior femoral nerve were transected, and the proximal stumps were ligated by using 5-0 nylon stitches to preclude spontaneous repair. A sham surgery (incision and exploration of the nerve) was performed at the same time (n=6). Before rat model established and at varying times after initial surgery (3 d, and 1, 2, 4, 6, and 8 weeks). ³¹P-MR spectra of rat quadriceps femoris were acquired on 7.0 T Agilent small animal MR imaging system. We quantified the phosphocreatine (PCr), adenosine triphosphate(β-ATP), and inorganic phosphate (Pi) using Creatine phosphate disodium salt(10 mmol/L) as an external standard. The ratios, include PCr/Pi, Pi/β-ATP, PCr/β-ATP, PCr/(PCr+Pi) and Pi/(PCr+Pi) were quantified in jMRUI. All data were analyzed by one way analysis of variance (ANOVA) with posttest inter-group comparisons using Bonferroni test. Comparative analysis methods between the experimental and control group were performed via independent samples t test. P<0.05 was considered as statistically significance. Results: The average measured concentrations of β-ATP, PCr, and Pi in control groups were (6.654±0.178) μmol/g, (25.656±0.738) μmol/g, and (1.594±0.096) μmol/g, respectively. There were significant statistically differences in β-ATP, PCr, Pi, PCr/Pi, PCr/PCr+Pi,Pi/PCr+Pi between the study and control group(P<0.05) at any measurement time point after denervation. Pi/β-ATP,PCr/β-ATP and pHi in the experimental group significantly statistically differed from those of the control group (all P<0.05)at each time point except on day 3 after operation. The total concentrations of β-ATP and PCr were reduced by 11.5% and 19.7% respectively on day 3. Thereafter, β-ATP and PCr declined rapidly by 63.1% and 68.8% at week 4 respectively, then decreased slowely by 74.0%和82.3% till week 10. The change of PCr/Pi is similar to β-ATP and PCr, but more remarkable. Pi, Pi/PCr+Pi, Pi/ATP showed a progressively increase till week 10. The intra-cellular pH (pHi) of normal rat muscles was 7.033±0.017, While the pHi gently in experiment rat muscles decreased during the entire experiment. Conclusion ³¹P-MRS with 7.0 T can quantify the temporal changes of energy metabolism and pHi in normal and denervated rat muscles. It shows that the dysfunction of energy metabolism are progressive with time and that they begin within a short period following the nerve section, the change of β-ATP, PCr, PCr/Pi take place primarily within 4 weeks after denervation. β-ATP, PCr, and PCr/Pi may be potential biomarkers of energy metabolism in the evaluation of denervated muscle atrophy.
