Objective:To investigate the expression and significance of programmed death ligand 1 (PD-L1) and programmed death 1 (PD-1) in colorectal cancer complicated by schistosomiasis.Methods:A total of 134 patients with colorectal cancer who received treatment in Xuancheng People's Hospital during 2014-2021 were included in this study. These patients consisted of 74 patients with colorectal cancer combined with schistosomiasis (patient group) and 60 patients with only colorectal cancer (control group). The expression of PD-L1 and PD-1 in colorectal cancer tissue was detected by an immunohistochemical method. The differences in PD-L1 and PD-1 expression were compared between the two groups. The relationships between PD-L1 and PD-1 expression and clinical pathological characteristics were determined.Results:The positive expression rates of PD-L1 and PD-1 in cancer cells and interstitial lymphocytes were 55.4% and 60.8% respectively in the patient group and they were 35.0% and 40.0% respectively in the control group. The positive expression rates of PD-L1 and PD-1 were significantly higher in the patient group than the control group ( χ2 = 5.55, 5.74, both P < 0.05). The expressions of PD-L1 and PD-1 in the patient group were correlated with lymph node metastasis and high tumor-node-metastasis stage ( P < 0.05). Conclusion:PD-L1 and PD-1 are highly expressed in colorectal cancer complicated by schistosomiasis and are related to their invasive behavior. PD-1/PD-L1 singaling pathway may be involved in the molecular mechanism underlying the occurrence and development of colorectal cancer complicated by schistosomiasis. Blocking PD-1/PD-L1 signaling pathway may be a new strategy for immunotherapy of colorectal cancer complicated by schistosomiasis.

ObjectiveTo systematically analyze the typical mental health conditions and psychological disorders of children with intellectual and developmental disabilities (IDD), to construct a mental health service system and psychological interventions to these mental health conditions of children with IDD . MethodsBased on the framework of the World Health Organization Family International Classifications (WHO-FICs), the mental health conditions and related functioning were analyzed, and the mental health service framework and proposed mental health interventions were constructed.There were six main categories of mental health conditions for children with IDDConclusionThis study systematically analyzed the typical mental health status and related psychological functional impairments of children with IDD. Based on the World Health Organization health service system, a mental health service framework for children with IDD was constructed. Referring to the WHO's continuum of health services, a system of psychological intervention methods for children with IDD was established. Furthermore, the WHO-FICs were used to describe and code the functions of children with IDD, and the ICHI-β3 was applied to code and analyze the related psychological interventions. Resultsmood disorders (anxiety and depression), behavioral disorders (disruptive disorders and challenging behaviors, aggressive behaviors), traumatic disorders (post-traumatic stress disorder), mental disorders (schizophrenia), suicide and self-harm, and learning disabilities (developmental learning disabilities, attention deficit hyperactivity disorder). Mental health services for children with IDD involved in six dimensions: leadership and governance, fundraising, human resources, service delivery, mental health technologies, and information and research. Mental health services went through the continuum of health services from prevention, treatment, rehabilitation to health promotion. We delivered mental health services for children with IDD in three aspects: identifying and diagnosing mental health problems or conditions, analyzing the main factors caused mental health problems, and analyzing the environmental factors. Mental health service interventions mainly covered five categories: antidepressants, psychotherapy, stress management training, physical exercise training, healthy lifestyle education, consultation and support. Children with IDD may obtain the mental health services in hospitals, rehabilitation institutions, community and school settings.

OBJECTIVE: To evaluate the effects of the pestle needling therapy on the vibration perception threshold (VPT) and the quality of life (QOL) in the patients of high-risk diabetic foot. METHODS: A total of 132 patients of high risk diabetic foot were randomized into an observation group and a control group, 66 cases in each one. In the control group, the routine treatment and nursing for diabetes were applied. In the observation group, on the base of the treatment as the control group, the pestle needling therapy was used at , , , Zusanli (ST 36), Yongquan (KI 1), Sanyinjiao (SP 6) and Taixi (KI 3). The intervention with the pestle needling therapy was given once every day, consecutively for 4 weeks. The follow-up visit was conducted in 3 months and 6 months after the intervention. Vibration perception threshold (VPT) was observed before and after intervention in the two groups. Separately, before intervention, at the end of intervention, 3 months after intervention and 6 months after intervention, the type 2 diabetes mellitus quality life scale (DMQLS), the revised edition was adopted to compare the QOL between the two groups. The effects were evaluated in the two groups. RESULTS: After intervention, the VPT and QOL were all improved in the two groups (<0.01, <0.05). In the observation group, after intervention, VPT at the first toes and the dorsum of the feet was lower than the control group at the same time point (all <0.01). In the observation group, the total scores and the score of each dimension item in the DMQLS of the revised edition were all lower than the control group correspondently at the end of intervention, 3 months after intervention and 6 months after intervention (<0.01, <0.05). The repeated ANOVA results showed that the differences were significant in the total scores and the score of each dimension in the aspects of time, inter-group and interaction effect (<0.01, <0.05). The total scores and score of each dimension item in the DMQLS were lower than those the earlier time point (<0.01, <0.05). The total effective rate was 100.0% in the observation group, which was superior to 95.1% (59/62) in the control group (<0.05). CONCLUSION The pestle needling therapy reduces the foot VPT and improves the sensory nerve function of the foot and the QOL in the patients of high-risk diabetic foot.

Tumor cells use glycolysis to provide material and energy under hypoxic conditions to meet the energy requirements for rapid growth and proliferation， namely the Warburg effect. Even under aerobic conditions， tumor cells mainly rely on glycolysis to provide energy. Therefore， glucose transporter protein 1（GLUT1）， which is involved in the process of glucose metabolism， plays an important role in tumorigenesis， development and drug resistance， and is considered to be one of the important targets in the treatment of malignant tumors. In recent years， research on tumor glucose metabolism has gradually become a hot spot. It has been shown that various factors are involved in the regulation of tumor energy metabolism， among which the role of GLUT1 is the most critical. In this paper， the authors reviewed the latest research progress of GLUT1-targeted traditional Chinese medicine（TCM） active ingredient nano-delivery system in tumor therapy， aiming to reveal the feasibility and effectiveness of this system in the delivery of chemotherapeutic drugs. The GLUT1-targeted TCM active ingredient nano-delivery system can overcome the bottleneck of the traditional targeting strategy as well as the high-permeability long retention（EPR） effect. In summary， the authors believe that the GLUT1-targeted TCM active ingredient nano-delivery system provides a new strategy for targeted treatment of tumors and has a broad application prospect in tumor prevention and treatment.
