OBJECTIVE To evaluate the long-term cost-effectiveness of canagliflozin or semaglutide in patients with type 2 diabetes mellitus（T2DM）poorly controlled with metformin. METHODS Based on the perspective of China’s health system， a Markov model was used to calculate the long-term costs and utilities of canagliflozin or semaglutide combined with metformin for T2DM patients in China for 30 years based on the data from SUSTAIN 8 study. The incremental cost-effectiveness ratio（ICER） and incremental net monetary benefit （INMB） were calculated using one time the 2024 per capita gross domestic product（GDP） as the willingness-to-pay（WTP） threshold. One-way sensitivity analysis， probability sensitivity analysis and scenario analysis were conducted to confirm the stability of the conclusions. RESULTS Compared with canagliflozin + metformin， ICER of semaglutide combined with metformin was 260 485.67 yuan/quality-adjusted life year （QALY），which was higher than the WTP threshold set in this study （95 749 yuan/QALY），and the corresponding INMB was －61 576.24 yuan，indicating that the canagliflozin + metformin regimen was more cost-effective. The cost of diabetes without complications treatment in the semaglutide + metformin group had the greatest influence on INMB，but changes in parameters within the selected range did not drive decision reversal. With the increasing of WTP threshold，the economic acceptability of semaglutide + metformin regimen increased. Under the current WTP threshold，the annual cost of semaglutide should be reduced by 42.95% to make the semaglutide + metformin regimen more cost- effective. CONCLUSIONS From the perspective of China’s health system， canagliflozin + metformin is more cost-effective than semaglutide + metformin for T2DM patients yueru. with poor glycemic control with metformin alone.

Multiple sclerosis (MS) is a neuroinflammatory demyelinating disease, mediated by pathogenic T helper 17 (Th17) cells. However, the therapeutic effect is accompanied by the fluctuation of the proportion and function of Th17 cells, which prompted us to find the key regulator of Th17 differentiation in MS. Here, we demonstrated that the triggering receptor expressed on myeloid cells 2 (TREM-2), a modulator of pattern recognition receptors on innate immune cells, was highly expressed on pathogenic CD4-positive T lymphocyte (CD4⁺ T) cells in both patients with MS and experimental autoimmune encephalomyelitis (EAE) mouse models. Conditional knockout of Trem-2 in CD4⁺ T cells significantly alleviated the disease activity and reduced Th17 cell infiltration, activation, differentiation, and inflammatory cytokine production and secretion in EAE mice. Furthermore, with Trem-2 knockout in vivo experiments and in vitro inhibitor assays, the TREM-2/zeta-chain associated protein kinase 70 (ZAP70)/signal transducer and activator of transcription 3 (STAT3) signal axis was essential for Th17 activation and differentiation in EAE progression. In conclusion, TREM-2 is a key regulator of pathogenic Th17 in EAE mice, and this sheds new light on the potential of this therapeutic target for MS.

Objective:To explore the recurrence pattern and prognosis of cervical cancer after radical chemoradiotherapy.Methods:Clinical and follow-up data of 1 359 patients with stage Ⅰ-ⅣA (International Federation of Gynecology and Obstetrics 2009 staging) who received radical radiotherapy in Zhejiang Cancer Hospital from August 2011 to December 2017 were retrospectively analyzed. The survival and prognostic factors of 249 patients with recurrence / metastasis with detailed data were analyzed. The primary endpoint was post-recurrence / metastasis survival time. Kaplan-Meier method was used to calculate the survival rate, log-rank test was used for single factor analysis, and Cox model was used for multi-factor analysis.Results:The distant metastasis rate of 249 patients was 77.5%, and the local recurrence rate was 36.9%. According to the location of metastasis and recurrence, 56 cases with recurrence in the field of radiotherapy alone were assigned into group A, 157 cases with recurrence outside the radiation field alone were allocated into group B (56 cases with lymph node recurrence in group B1, 78 cases with blood metastasis in group B2, and 23 cases with lymph node and blood metastasis simultaneously in group B3), and 36 cases with combined recurrence and metastasis in and out of the field of radiotherapy were assigned into group C. The median survival time of patients in groups A, B1, B2, B3 and C was 13, 24, 13, 11 and 9 months, respectively (all P<0.001). According to the interval from initial diagnosis to recurrence / metastasis, 110 cases were classified in ≤1 year group, 74 cases in >1-2 years group, and 65 cases in >2 years group. The median survival time of patients in the three groups was 11, 14, and 22 months, respectively (all P<0.001). According to the management of recurrence / metastasis, 138 cases received palliative treatment, 15 cases received local treatment, 45 cases received systemic treatment, and 51 cases received combined treatment. The median survival time of patients among four groups was 9, 37, 20 and 32 months, respectively (all P<0.001). The results of multi-factor analysis showed that age, recurrence / metastatic site, retreatment methods, time interval between initial treatment and recurrence /metastasis were the independent prognostic factors affecting the survival (all P<0.05). Conclusions:Distant metastasis is the main failure pattern after radical radiotherapy. Patients with metastasis out of irradiated regions, especially those with only lymph node metastasis, have good prognosis. Active retreatment and time interval between initial diagnosis and recurrence / metastasis are important prognostic factors.

Objective To explore the general surgery patients with postoperative incision infection(SSI)of pathogenic microorganism distribution characteristics and serum lactate dehydrogenase(LDH),interleukin(IL)-6 to the predictive value of infection.Methods A total of 100 patients who underwent surgery in the General Surgery Department of the hospital from January 2021 to June 2023 were selected as the research ob-jects.According to the occurrence of postoperative infection,the patients were divided into infection group(28 cases)and non-infection group(72 cases).The basic data of the patients were collected,including age,gender,operation type,operation time,incision type,and incision healing.Bacterial culture and pathogen identification were performed on the incision secretion of patients under sterile conditions.At the same time,the serum LDH and IL-6 levels of the patients on the first and third day after operation were detected,and the differences of LDH and IL-6 levels between the infection group and the non-infection group were compared.Pearson cor-relation analysis was used to analyze the correlation between serum LDH level and IL-6.Multivariate Logistic regression analysis was used to analyze the influencing factors of SSI.The receiver operating characteristic(ROC)curve was drawn to analyze the diagnostic efficacy of serum LDH and IL-6 levels for SSI.Results A-mong the 100 patients,28 patients developed SSI,and the infection rate was 28％.There were significant differences in age,operation time,and incision type between the infection group and the non-infection group(P＜0.05).The results of bacterial culture showed that a total of 35 strains of bacteria were isolated from the patients in the infection group,of which Gram-positive bacteria accounted for 54.29％and Gram-negative bac-teria accounted for 45.71％,mainly Staphylococcus aureus(14 strains),Pseudomonas aeruginosa(7 strains),and Escherichia coli(5 strains).The serum levels of LDH and IL-6 in the infection group were higher than those in the non-infection group on postoperative days 1 and 3(P＜0.05).The serum level of LDH in the in-fection group was positively correlated with IL-6(r=0.512,P＜0.001).Multivariate Logistic regression a-nalysis showed that age,operation time,type of incision,and serum LDH and IL-6 levels on postoperative day 3 were independent risk factors for SSI(P＜0.05).ROC curve analysis showed that serum LDH and IL-6 lev-els had a high diagnostic efficacy for SSI,with an area under the curve of 0.89 and 0.88,the best cut-off values of 210 U/L and 15 pg/mL,the sensitivity of 82.14％and 85.71％,and the specificity of 78.57％and 80.36％,respectively.Conclusion Staphylococcus aureus and Pseudomonas aeruginosa are the main pathogenic micro-organisms of SSI in general surgical patients.Serum LDH and IL-6 levels can be used as predictors of SSI,which is of great significance for early diagnosis and treatment of infection.

To explore the level of hsa_circ_0001588 in plasma of patients with gastric cancer and to analyze the relationship between the plasma level of hsa_circ_0001588 and clinical characteristic,toll like receptors 4(TLR4)and T lymphocyte subsets,this study enrolled 124 gastric cancer patients who were treated in our hospital from March 2021 to May 2022 as study group.Simultaneously,another 130 patients diagnosed with superficial gastritis by gastroscopy were selected as benign group,and 130 healthy individuals were set as control group.The plasma hsa_circ_0001588 level was measured by quantitative real-time polymerase chain reaction,the plasma level of TLR4 was detected by double antibody sandwich ELISA,and plasma CD3+,CD4+,CD8+,and CD4+/CD8+levels were tested by Wmini5146 flow cytometry.Then the diagnostic efficacy of plasma hsa_circ_0001588,TLR4 and T lymphocytes for gastric cancer was evaluated,and the correlation between the level of hsa_circ_0001588 in plasma and the level of TLR4 and T lymphocytes in gastric cancer patients was verified.Data showed that the levels of hsa_circ_0001588,TLR4 and CD8+in plasma of study group were higher than those of benign group and control group,while the levels of CD3+,CD4+and CD4+/CD8+were lower than those of benign group and control group(P＜0.05).Furthermore,a decrease was observed in plasma hsa_circ_0001588 level in gastric cancer patients after surgery compared to baseline data.Among gastric cancer patients of different clinicopathological characteristics,patients with high clinical stage,high degree of infiltration,poor differentiation and distant metastasis had high plasma hsa_circ_0001588 level(P＜0.05).Diagnostic analysis denoted that the separate test of plasma hsa_circ_0001588,TLR4 and T-lymphocytes all had good diagnostic efficacy for gastric cancer,while combined test showed the highest diagnostic efficacy.Comparison among gastric cancer patients revealed that high hsa_circ_0001588 expression group had lower expression of CD3+,CD4+and CD4+/CD8+,and higher expression of TLR4 and CD8+than those of low hsa_circ_0001588 expression group(P＜0.05),suggesting that plasma hsa_circ_0001588 level was negatively correlated with CD3+,CD4+and CD4+/CD8+expression,but positively correlated with TLR4 and CD8+.In conclusion,the level of hsa_circ_0001588 in plasma is elevated in patients with gastric cancer,and it has a negative correlation with CD3+,CD4+and CD4+/CD8+,but positive correlation with TLR4 and CD8+expression.

Objective To understand the implementation of the nursing group standards for oxygen inhalation therapy in clinical practice,and to provide a reference for improving the nursing practice of oxygen therapy.Methods A convenience sampling method was used to investigate nurses from 902 hospitals in 24 provinces and municipalities directly under the central government using a self-designed questionnaire from December 15th,2022,to January 14th,2023.The content of questionnaire included whether they had implemented the recommendations of the oxygen therapy standards,the knowledge of safety related to oxygen therapy,and the components of oxygen therapy prescriptions,the indications used for patients receiving oxygen therapy and practice status of oxygen therapy.Results A total of 10481 questionnaires were returned,of which 10447 were valid,with a valid questionnaire recovery rate of 99.68%.63.14%of the nurses indicated that the hospital had organized training on oxygen therapy standards.Only 47.82%of nurses know the correct use of the Venturi mask.41.90%of nurses could indicate the correct indicator of flow adjustment.31.88%of the nurses stated that they will adjust the oxygen flow rate based on the oxygenation status of carbon dioxide storage patients.Only 19.56%of nurses indicated that humidification is applied in oxygen therapy based on the oxygen flow and duration.Conclusion Even though nurses had received training related to oxygen therapy standards,the level of knowledge of oxygen therapy standards was still low;therefore continuous systematic training was needed,and the implementation of the content of oxygen therapy standards needed to be further standardized.Healthcare institutions would focus on organizing systematic training and maintaining the training effect,enhancing infrastructure and providing support for implementation.Recommendation to the nursing administration is to explore how to comprehensively and continuously implementing the oxygen therapy nursing standards with the ultimate goal of providing patients safer and more accurate oxygen therapy.

The use of digital means has made the public health emergency management more efficient and convenient. However, in the practice of managing public health emergencies, there are dilemmas in the protection of personal health information, such as the imperfect legal system, the weakened right of informed consent and control, the lack of reasonable norms in the collection and use of information, and the disclosure of personal health information. To solve the dilemma of personal health information protection, it is necessary to improve the corresponding legal mechanism, strengthen the classification of health information, standardize the behavior of health information collection and use, enhance the technical support of personal health information protection, build a system combining law and technology, and protect the security of personal health information.

Objective:To explore the application potential of 18F-Asp-Glu-val-Asp (DEVD)-Cys(StBu)-PPG(CBT)-AmBF 3 ( 18F-1; PPG: propargyl-glycine; CBT: 2-cyanobenzothiazole; AmBF 3: ammoniomethyl-trifluoroborate) PET imaging in early monitoring of triple-negative breast cancer (TNBC) radiotherapy response. Methods:Ten MDA-MB-231 tumor bearing nude mice models were constructed and divided into radiotherapy group ( n=5) and non-radiotherapy group ( n=5) by random sampling method. The radiotherapy group was treated with single irradiation at a dose of 8 Gy. 18F-1 microPET imaging was performed in the radiotherapy and non-radiotherapy groups, and the tumor uptake and muscle uptake in 2 groups at different time points (2.5, 7.5, 12.5, 17.5, 22.5, 27.5, 32.5, 37.5, 42.5, 47.5, 52.5, 57.5 min after injection) were analyzed. The specific uptake of the probe in apoptotic cells was verified by radioautography, HE staining and immunofluorescent staining. Repeated measures analysis of variance and one-way analysis of variance were used to analyze data. Results:18F-1 microPET imaging showed that there was significant difference between tumor uptake and muscle uptake in radiotherapy group ( F=20.27, P=0.011). The uptake of radiotherapy group was the highest at 7.5 min after injection ((4.64±0.35) percentage activity of injection dose per gram of tissue(%ID/g)). There was no significant difference between tumor uptake and muscle uptake in the non-radiotherapy group ( F=1.81, P=0.215). The tumor/muscle (T/M) ratio of radiotherapy group was higher than that of non-radiotherapy group ( F=31.95, P=0.005), with the highest at 47.5 min after injection (2.49±0.46). Radioautography showed that the tumor radioactivity in radiotherapy group was higher than that of muscle in radiotherapy group, and was also higher than tumor and muscle radioactivies in non-radiotherapy group ( F=116.79, P<0.001). HE staining and immunofluorescent staining verified that 18F-1 could specifically detect the activity of caspase-3 activated in tumor cells after radiotherapy. Conclusion:18F-1 can specifically recognize the activated caspase-3 after TNBC radiotherapy, and monitor radiotherapy response at the molecular level by apoptosis PET imaging.
