Objective To construct and apply an intelligent follow-up information system for patients with cancer pain,providing references for improving the efficiency of hospital follow-up and promoting pain management of patients at home.Methods The intelligent discharge follow-up system for patients with cancer pain includes 2 platforms,namely a patient self-report platform and an administrator operation platform.The administrator operation platform consists of 5 modules,namely the workbench module,the follow-up plan module,the follow-up results module,the health education module and the data statistics module.In January 2022,the system was officially put into clinical application.The use of the system was analyzed,and patients'completion rate,medication compliance,incidence of moderate and severe pain and satisfaction with pain control were compared before(from January 2020 to December 2021)and after(from January 2022 to November 2023)the application of the system.Results At present,this system has been applied in 95 cancer-related wards of our hospital.From January 2022 to November 2023,the number of people who should be followed up was 4 248,and the number of people who actually completed the follow-up was 4 127;the rate of follow-up completion was 97.2%;the rate of timely completion of the follow-up was 94.9%;the rate of automatic follow-up by the system was 40.1%;the rate of patient abnormality report was 31.9%;the rate of timely treatment of patient abnormality report was 89.1%.After the application of the system,the completion rate of pain follow-up was increased,and the difference was statistically significant(P<0.001).After the application of the system,the medication compliance rate of patients with cancer pain increased from 86.9%to 91.0%;the incidence of moderate and severe pain decreased from 6.8%to 5.2%;the satisfaction with pain control increased from 81.0%to 83.5%(P<0.05).Conclusion The intelligent discharge follow-up system for patients with cancer pain can effectively improve the discharge follow-up efficiency and promote the management of patients with cancer pain at home.

A 28-year-old woman presented with a 4-year history of fatigue and sleepiness and was found to have central hypothyroidism and mood disorder. The patient had normal thyroid volume and did not show any other pituitary axis involvement. Over the course of the disease, her symptom improvement matched with the free thyroxine (FT 4) rebound and the adjustment of antipsychotic medication. The patient′s grandmother had central hypothyroidism, and her mother and uncle had lowered or inappropriately normal thyroid stimulating hormone. Hence, genetic involvement was highly suspected, but whole exon sequencing did not reveal a pathogenic variant. Levothyroxine tablets were prescribed to maintain a normal median level of FT 4, and mood disorder medications were adjusted by specialists. Isolated central hypothyroidism is extremely rare, and we report this case aiming to raise awareness of this condition.

Objective To construct a risk prediction model by integrating the molecular subtypes of pan-creatic ductal adenocarcinoma(PDAC)and immune-related genes.Methods With GSE71729 data set(n=145)as the training set,the differentially expressed genes and differential immune-related genes between the squamous and non-squamous subtypes of PDAC were integrated to construct a regulatory network,on the basis of which five immune marker genes regulating the squamous subtype were screened out.An integrated immune score(IIS)model was constructed based on patient survival information and immune marker genes to predict the clinical prog-nosis of PDAC patients,and its predictive performance was tested with 5 validation sets(n=758).Results PDAC patients were assigned into high risk and low risk groups according to the IIS.In both training and validation sets,the overall survival of patients in the high risk group was shorter than that in the low risk group(both P＜0.001).The multivariable Cox regression showed that IIS was an independent prognostic factor for PDAC(HR=2.16,95％CI=1.50-3.10,P＜0.001).Conclusion IIS can be used for risk stratification of PDAC patients and may become a potential prognostic marker for PDAC.

OBJECTIVE To study the regulation effects and mechanism of liquiritin （LIQ） on immune function in gastric cancer-bearing mice based on the Janus kinase 2 （JAK2）/signal transducer and activator of transcription 3 （STAT3） pathway. METHODS Gastric cancer cells MFC were injected subcutaneously to establish gastric cancer-bearing model of mice. The model mice were divided into model group， LIQ low-dose group （LIQ-L group， 20 mg/kg）， LIQ high-dose group （LIQ-H group， 40 mg/kg）， and high-dose LIQ+JAK2 activator coumermycin A1 group （LIQ-H+coumermycin A1 group， 40 mg/kg LIQ+1 mg/kg coumermycin A1）， with 12 mice in each group. Another 12 mice without modeling were set as normal group. Mice in each group were given the corresponding drug or normal saline by intragastric administration/intraperitoneal injection， once a day， for consecutive 14 days. After the last administration， the volume and mass of gastric cancer tumor and organ index were measured. The percentages of CD4+ and CD8+T lymphocytes were detected in peripheral blood. The histopathological morphology of gastric cancer tumor tissues was observed， and the expression levels of JAK2/STAT3 signaling pathway-related proteins and interleukin-6 （IL-6） protein in gastric cancer tumor tissues were detected. RESULTS Compared with the normal group， the thymus index， spleen index， and the percentage of CD8 T lymphocyte in the peripheral blood of mice were obviouslyincreased in model group （P＜0.05）， while the percentage of CD4+T lymphocyte in the peripheral blood were decreased （P＜0.05）. Compared with model group， the above indexes in LIQ-L group and LIQ-H group were significantly reversed （P＜0.05）， while the volume and mass of gastric cancer tumor， the phosphorylation levels of JAK2 and STAT3 protein and the expression level of IL-6 protein were significantly decreased in tumor tissue （P＜0.05）， and the effect of LIQ was in a dose-dependent manner （P＜0.05）； the tumor cells showed varying degrees of loose arrangement， vacuolization， and uneven distribution. JAK2 activator coumermycin A1 weakened the improvement effect of LIQ on the immune function of gastric cancer-bearing mice and its inhibitory effect on gastric cancer tumors （P＜0.05）. CONCLUSIONS LIQ can improve the immune function of gastric cancer-bearing mice by inhibiting the activation of JAK2/STAT3 signaling pathway， thus playing an anti-tumor role.

The clinical manifestations of colorectal polyps are consistent with the characteristics of dampness, stickiness and heaviness. The TCM constitutions in the prone population are mostly related to dampness. The pathological changes of intestinal flora imbalance, intestinal micro inflammation, neuroendocrine immune network and abnormal aquaporin in colorectal polyps are consistent with the research results of modern mechanism of dampness pathogen. This article believed that the TCM pathogenesis of colorectal polyps caused by damp pathogen is the accumulation of spleen deficiency and dampness caused by improper diet, poor emotion and other factors, and the interweaving of various diseases and pathogens to form tangible foreign bodies. According to the pathogenic characteristics of damp pathogen and the pathogenic factors of colorectal polyps, the influence of damp pathogen on the pathogenesis of colorectal polyps was discussed, in order to provide an effective TCM theoretical basis for the diagnosis and treatment of colorectal polyps in clinic.

Pyroptosis, an inflammatory caspase-dependent programmed cell death, plays a vital role in maintaining tissue homeostasis and activating inflammatory responses. Orthodontic tooth movement (OTM) is an aseptic force-induced inflammatory bone remodeling process mediated by the activation of periodontal ligament (PDL) progenitor cells. However, whether and how force induces PDL progenitor cell pyroptosis, thereby influencing OTM and alveolar bone remodeling remains unknown. In this study, we found that mechanical force induced the expression of pyroptosis-related markers in rat OTM and alveolar bone remodeling process. Blocking or enhancing pyroptosis level could suppress or promote OTM and alveolar bone remodeling respectively. Using Caspase-1^-/- mice, we further demonstrated that the functional role of the force-induced pyroptosis in PDL progenitor cells depended on Caspase-1. Moreover, mechanical force could also induce pyroptosis in human ex-vivo force-treated PDL progenitor cells and in compressive force-loaded PDL progenitor cells in vitro, which influenced osteoclastogenesis. Mechanistically, transient receptor potential subfamily V member 4 signaling was involved in force-induced Caspase-1-dependent pyroptosis in PDL progenitor cells. Overall, this study suggested a novel mechanism contributing to the modulation of osteoclastogenesis and alveolar bone remodeling under mechanical stimuli, indicating a promising approach to accelerate OTM by targeting Caspase-1.
