Objective:To establish an early warning model to assess the mortality risk of patients with heat stroke disease.Methods:The case data of patients diagnosed with heat stroke disease admitted to the comprehensive ICU of Shanshan County from January 2016 to December 2020 were selected. According to the short-term outcome (28 days) of patients, they were divided into death group (20 cases) and survival group (53 cases) . The relevant indicators with statistically significant differences between groups within 24 hours after admission were selected. By drawing the subject work curve (ROC) and calculating the area under the curve, the relevant indicators with the area under the curve greater than 0.7 were selected, Fisher discriminant analysis was used to establish an assessment model for the death risk of heat stroke disease. The data of heat stroke patients from January 1, 2021 to December 2022 in the comprehensive ICU of Shanshan County were collected for external verification. Results There were significant differences in age, cystatin C, procalcitonin, platelet count, CKMB, CK, CREA, PT, TT, APTT, heart rate, respiratory rate and GLS score among the groups. Cystatin C, CKMB, CREA, PT, TT, heart rate AUC area at admission was greater than 0.7. Fisher analysis method is used to build a functional model.Results:The diagnostic sensitivity, specificity and AUC area of the functional model were 95%, 83% and 0.937 respectively. The external validation results showed that the accuracy of predicting survival group was 85.71%, the accuracy of predicting death group was 88.89%.Conclusion:The early warning model of heat stroke death constructed by ROC curve analysis and Fisher discriminant analysis can provide objective reference for early intervention of heat stroke.

OBJECTIVE: To explore the effectiveness of arthroscopic treatment of scaphoid fracture nonunion with bone graft and Kirschner wire combined with screw fixation. METHODS: The clinical data of 14 patients with scaphoid fracture nonunion who met the selection criteria between February 2021 and September 2022 were retrospectively analyzed. There were 13 males and 1 female with an average age of 32 years ranging from 17 to 54 years. The time from injury to operation ranged from 6 to 15 months, with an average of 9.6 months. According to the Slade-Geissler classification of scaphoid fracture nonunion, there were 3 cases of grade Ⅲ, 8 cases of grade Ⅳ, and 3 cases of grade Ⅴ. The preoperative visual analogue scale (VAS) score was 5.9±1.0, and the modified Mayo wrist score was 53.2±9.1. There were 2 cases of scaphoid nonunion advanced collapse, both of which were stage Ⅰ. All patients were treated with arthroscopic bone graft and Kirschner wire combined with screw fixation, and the fracture healing was observed by X-ray film monthly after operation, and the effectiveness was evaluated by VAS score and modified Mayo wrist score before and after operation. RESULTS: All patients were followed up 6-14 months, with an average of 8.4 months. All fractures healed in 4-8 months, with an average of 6.3 months. The postoperative pain symptoms and wrist function of the patients significantly improved when compared with those before operation, and the VAS score at last follow-up was 2.4±1.3, and the modified Mayo wrist score was 87.1±6.7, which were significantly different from those before operation ( t=12.851, P<0.001; t=-14.410, P<0.001). According to the modified Mayo wrist evaluation, 9 cases were excellent, 3 cases were good, and 2 cases were fair. CONCLUSION Arthroscopic bone graft and Kirschner wire combined with screw fixation is an effective surgical method for the treatment of scaphoid fracture nonunion.

Objective To establish an efficient method for isolating migrasomes from RAW264.7 macrophages and identifying these isolated migrasomes. Methods Scanning electron microscopy was used to observe the morphological characteristics of migrasomes produced by RAW264.7 cells. A 0.45 μm filter was employed for reverse filtration and elution to isolate the migrasomes. The morphological characteristics of the migrasomes were then observed using transmission electron microscopy. Western blot analysis was performed to determine the expression of characteristic markers of the migrasomes. The RNA carried by the migrasomes was analysed by using LabChip bioanalyzer. Results Scanning electron microscopy revealed that the migrasomes, with membranous structures, were attached to the tip or bifurcation of the retraction fiber formed in the tail of RAW264.7 cells. Transmission electron microscopy showed that the isolated migrasomes had a typical oval vesicle-like structure with wrinkled membrane surfaces. Western blot analysis confirmed the expression of the characteristic markers phosphatidylinositol glycan anchor biosynthesis class K (PIGK), epidermal growth factor domain-specific O-linked N-acetylglucosamine transferase (EOGT) and tetraspanin 4 (TSPAN4) in the migrasomes, while the EV (extracellular vesicle) markers tumor susceptibility gene 101 (TSG101) and Arabidopsis homolog of apoptosis-linked gene 2-interacting protein X (ALIX) were not detected. Furthermore, the isolated migrasomes were found to be rich in small RNA, which were approximately 25-200 nt in length. Conclusion A method for the extraction of well-structured and high quality migrasomes from macrophages is established.

Objective:To study the population distribution of Pomacea spp. in Shandong Province and the risk of angiostrongyliasis cantonensis in the local population, and to provide a basis for scientific prevention and control of related diseases. Methods:From July to December 2021, Yanzhou District of Jining City, Ningyang County of Taian City, and Dongying District of Dongying City were selected as surveillance sites to investigate the population and distribution range of Pomacea spp., live snail samples were collected for morphological and genetic identification, and Pomacea spp. infected with the larva of Angiostrongylus cantonensis was detected by lung test. At the same time, sentinel hospital case surveillance was carried out in Yanzhou District, Jining City, and questionnaire was used to study the local residents' awareness of angiostrongyliasis cantonensis and their personal health behaviors. Results:A total of 312 live snail samples were collected. After morphological identification, they were all Pomacea spp.. After gene sequencing, two populations of Pomacea canaliculata and Pomacea maculata were found. No positive snails infected with Angiostrongylus cantonensis were found. A total of 126 patients with headache as the main neurological symptom were admitted to the sentinel hospital, but there were no monitoring cases that met the inclusion criteria. Among the survey population, 48.38% (134/277) of the respondents had heard of angiostrongyliasis cantonensis, 44.77% (124/277) knew that eating Margarya melanioides might cause angiostrongyliasis cantonensis, and 83.39% (231/277) had no related unhealthy eating behavior. Conclusion:Pomacea spp. is found and reported for the first time in Shandong Province, and there is a risk of population infection with angiostrongyliasis cantonensis.

Malignant tumor ranks as a leading cause of human death. Guanylate binding protein 5 (GBP5) belongs to the family of interferon-γ-inducible large GTPase superfamily and participates in various pathological and physiological processes. A growing number of studies have indicated that GBP5 is involved in the malignant progression of tumors. This article mainly reviews the biological characteristics of GBP5 and its expression, regulation and function in tumors, in the hope of providing a theoretical basis for the diagnosis and treatment of tumors.

Obesity and type 2 diabetes (T2DM) are all the metabolic diseases with high incidence rate. There is a clear correlation between the them. Weight-loss surgery is the important treatment of surgical method for obesity and T2DM.However, the mechanism of T2DM for weight loss surgery is not yet clear.The secretion level of glucagon like peptide-1 (GLP-1) was affected after weight loss surgery. The secretion of GLP-1 can delay gastric emptying, increase satiety, improve insulin resistance (IR) and promote β insulin release, inhibition of glucagon synthesis and secretion, and improvement of pancreatic function β cell function. All of these changes were conducive to glycemic control. Therefore, this paper aims to summarize and describe the relationship between the effect of laparoscopic sleeve gastrectomy (LSG) on blood glucose and GLP-1/dipeptidyl peptidase-4 (DPP-4) pathway in obese T2DM patients.

Lung cancer is one of the most common malignancies with the highest incidence rate and mortality rate worldwide, and non-small cell lung cancer (NSCLC) accounts for about 85%. Only 5% NSCLC patients are anaplastic lymphoma kinase (ALK) rearrangement positive NSCLC, but the prognosis of these patients is poor, and treatment is urgent. Ensartinib (X-396), a next-generation ALK tyrosine kinase inhibitor (ALK-TKI), has shown greater potency on inhibiting ALK activity and controlling brain metastases than crizotinib, which is indicated for the treatment of crizotinib-resistant, ALK-positive NSCLC patients. Several phase I to III clinical trials included both healthy volunteers and NSCLC patients have been conducted both in China and abroad. In this review, we briefly summarized the results of these trials, and preliminary efficacy, safety, pharmacology and pharmacokinetics/pharmacodynamics of ensartinib were discussed.

Blastocystis sp. is a kind of protozoa living in the intestinal tract of human and animals, which will cause intestinal diseases such as diarrhea, abdominal distension and vomiting. This paper was aimed to understand the infection of Blastocystis sp. In golden monkeys and the transmission path in North China. Thirty-seven feces samples from golden monkeys and 116 cockroach samples from Shijiazhuang Zoo were collected from July to October 2019 for PCR analysis of Blastocystis sp. Genetic diversity analysis was further conducted on the samples with positive PCR results. The results showed that the infection rate was 48.7% (18/37) in golden monkeys and 82.8% (96/116) in cockroaches, respectively. The genetic evolution analysis based on small subunit ribosomal RNA demonstrated that three subtypes (ST) of Blastocystis sp. including ST1, ST2, and ST3 existed in the intestinal tract of golden monkeys, while only ST2 was detected in the intestinal tract of cockroaches. This paper may provide supports for the quarantine and control of Blastocystis sp. for the zoo in Northern China.
