OBJECTIVE From the perspective of China’s healthcare system, to evaluate the cost-effectiveness of tislelizumab in patients with locally advanced or metastatic squamous or non-squamous non-small cell lung cancer (NSCLC) whose disease progresses or is intolerable after receiving platinum-containing dual chemotherapy in the past. METHODS Rationale-303 research data were used to construct a partitioned survival model. The model period was set to be 21 days and simulated to 120 months. Using quality-adjusted life year (QALY) as a health output index, the incremental cost-effectiveness ratio (ICER) was calculated by discounting cost and health output with a discount rate of 5%. Single-factor sensitivity analysis and probability sensitivity analysis were performed to verify the robustness of the basic analysis results. RESULTS Cost-utility analysis results showed that the ICER of tislelizumab group was 65 653.52 yuan/QALY, compared with docetaxel group. This means that the regimen of tislelizumab was more cost-effective than the docetaxel regimen when the willingness-to-pay threshold (WTP) was 3 times China’s gross domestic product (GDP) per capita in 2023 (268 200 yuan/QALY). The results of single-factor sensitivity analysis showed that the three parameters that had a greater impact on ICER were the prices of tislelizumab, docetaxel and pemetrexed. The results of the probabilistic sensitivity analysis showed that the probabilities of the above two treatment regimens being cost-effective were both 50% when the WTP threshold was approximately 65 000 yuan/QALY. The probability of tislelizumab regimen being cost- effective was 100% when the WTP threshold was ≥134 000 yuan/QALY. CONCLUSIONS From the perspective of China’s healthcare system, when taking 3 times China’s GDP per capita in 2023 as the WTP threshold, tislelizumab is cost-effective for patients with locally advanced or metastatic squamous or non-squamous NSCLC after receiving platinum-containing dual chemotherapy in the past, compared with docetaxel.

BACKGROUND:
The potential impact of pre-existing coronary artery stenosis (CAS) on right ventricular (RV) function during acute pulmonary embolism (PE) episodes remains underexplored. This study aimed to investigate the association between pre-existing CAS and RV dysfunction in patients with acute PE.
METHODS:
In this multicenter, case-control study, 89 cases and 176 controls matched for age were enrolled at three study centers (Peking Union Medical College Hospital, Fuwai Hospital, and the Second Affiliated Hospital of Harbin Medical University) from January 2016 to December 2020. The cases were patients with acute PE with CAS, and the controls were patients with acute PE without CAS. Coronary artery assessment was performed using coronary computed tomographic angiography. CAS was defined as ≥50% stenosis of the lumen diameter in any coronary vessel >2.0 mm in diameter. Conditional logistic regression analysis was used to evaluate the association between CAS and RV dysfunction.
RESULTS:
The percentages of RV dysfunction (19.1% [17/89] vs. 44.6% [78/176], P <0.001) and elevated systolic pulmonary artery pressure (sPAP) (19.3% [17/89] vs. 39.5% [68/176], P = 0.001) were significantly lower in the case group than those in the control group. In the multivariable logistic regression model, CAS was independently and negatively associated with RV dysfunction (adjusted odds ratio [OR]: 0.367; 95% confidence interval [CI]: 0.185-0.728; P = 0.004), and elevated sPAP (OR: 0.490; 95% CI: 0.252-0.980; P = 0.035), respectively.
CONCLUSIONS
Pre-existing CAS was significantly and negatively associated with RV dysfunction and elevated sPAP in patients with acute PE. This finding provides new insights into RV dysfunction in patients with acute PE with pre-existing CAS.

Dysregulation of transforming growth factor β (TGF- β) signaling pathway is related to the occurrence and development of various pathological conditions, including tumors. In the early stage of tumorigenesis, TGF- β, as an anti- proliferation and pro-differentiation factor, plays an anticancer role. In advanced tumors, TGF-β can stimulate tumor progression and metastasis through its effect on the tumor microenvironment (such as promoting angiogenesis, fibrosis, immune suppression, and regulating cellular metabolism). A variety of TGF-β signaling pathway inhibitors have been tested in clinical trials, including monoclonal antibodies, ligand traps, small molecule inhibitors, antisense oligonucleotides, bispecial antibodies, and tumor vaccines, but no related drugs are currently approved for cancer treatment clinically. Accurately screening potential benefit patients and combining it with immune checkpoint inhibitors are its future development directions.

Objective:To construct a teaching ability evaluation system for diversified general medicine course teachers under the guidance of "one practice and three learning".Methods:A research group was established to search for relevant documents and literature. A framework of evaluation index system was established through drafting and repeated discussion and modification by members of the group, as well as further discuss and modification by experts in general medicine. The framework was used to develop an expert consultation questionnaire on the teaching ability evaluation system for diversified general medicine course teachers under the guidance of "one practice and three learning". Through two rounds of expert consultation, a teaching ability evaluation system for diversified general medicine teachers under the guidance of "one practice and three learning" was constructed. A questionnaire was developed according to the system. The rationality and scientificity of the evaluation index system were verified by questionnaire survey.Results:The teaching ability evaluation system for diversified general medicine teachers under the guidance of "one practice and three learning" included 3 first-level indicators, 15 second-level indicators, and 41 third-level indicators. The general medicine curriculum evaluation questionnaire developed on the system showed that the Cronbach's α coefficient of the overall evaluation system was 0.981. The Cronbach's α coefficients of first-level indicators, including general medicine teaching plan, diversified theory and practice teaching, and comprehensive ability cultivation under the guidance of "one practice and three learning" ideology, were 0.920, 0.919, and 0.923, respectively. The content validity index (S-CVI) of the system was 0.981, and the content validity index (I-CVI) of indicators were 0.826-1.000. The correlation coefficients of first-level indicators and the system were 0.837-0.942 (all P<0.05). The correlation coefficients of second-level indicators and their corresponding first-level indicators were 0.586-0.971 (all P<0.05). The correlation coefficients of third-level indicators and their corresponding first-level indicators were 0.412-0.904 (all P<0.05). Conclusions:Under the guidance of "one practice and three learning", the teaching ability evaluation indicators for diversified general medicine course teachers have high specificity, rationale structure, high feasibility, high reliability, and high practicability. This evaluation system can provide theoretical reference for the training of undergraduate students in general medicine.

Background Nonylphenol (NP) is a typical phenolic endocrine disruptor, and there are significant differences in NP concentration in different regions and water types. Objective To investigate the concentration of NP in three types (river, lake, and reservoir) of water sources in Hubei Province, and assess its ecological risk and population health risk. Methods Fifteen sampling points were set up at four river water sources (Liangtingshan Waterworks, Baishazhou Waterworks, Dijiao Waterworks, and Zongguan Waterworks), one lake water source (Liangzi Lake), and one reservoir water source (Fushui Reservoir). Water samples were collected from the 15 sampling points in June 2019 (wet season), October 2019 (level season), and December 2019 (dry season), respectively. The NP concentration in water samples was detected using ultra-high-performance liquid chromatography-tandem mass spectrometry, and the differences in NP concentration among groups were compared using variance analysis. The ecological risk and the health risk of NP were evaluated using risk quotient (RQ) and non-carcinogenic risk index (NCRI), respectively. Results The detection rate of NP was 100%, with an average concentration of (18.10±15.00) ng·L−1 (5.45-92.71 ng·L−1). The average concentrations of NP during the level, wet, and dry seasons were (11.52±5.31) ng·L−1, (23.86±22.08) ng·L−1, and (18.93±9.51) ng·L−1, respectively, and the maximum concentrations were 24.62 ng·L−1, 92.71 ng·L−1, and 42.38 ng·L−1, respectively. The variance analysis showed no statistical difference in the NP concentration in the samples from rivers, lakes, and reservoirs in different periods (P>0.05). Only the water samples from the water source serving the Zongguan Waterworks showed an RQ (0.19) greater than 0.1 during the wet season, indicating a moderate risk. The RQ values of other water samples were all less than 0.1, indicating an overall relatively low ecological risk. The highest NCRI values during the level, wet, and dry seasons were 0.1459, 0.5492, and 0.2511, respectively, all less than 1, indicating an acceptable health risk level. Conclusion The NP concentrations in all water sources in this study are at a relatively low level, which poses an acceptable risk level to human health.

Objective:To evaluate the effect of nursing specialist nurses′ assistance on the ability of nursing home nurses to maintain venous catheter under the vision of combination of medical care and nursing care, providing reference for carrying out specialized nursing assistance work in grassroots hospitals.Methods:This study was an experimental study. According to Miller′s pyramid theory, a model of specialist nurse assistance was established with specialized technology as the core. From January to December 2021, three nursing hospitals in Suzhou were assisted. Convenience sampling method was used to investigate the ability of intravenous catheter maintenance, the incidence of central venous catheter maintenance defects, the incidence of central venous catheter complications and unplanned extubation, and the satisfaction of doctors and patients before and after help.Results:Totally 86 nurses were included, aged (33.17 ± 2.31) years old. After the help, the theoretical and operational skill scores of nurses in the nursing home were (89.77 ± 2.11) and (92.75 ± 1.62) points, respectively, which were significantly higher than those before the help (60.84 ± 2.71) and (79.81 ± 1.68) points, and the differences were statistically significant ( t=-84.96, -52.12, both P<0.05). Among the maintenance defects of central venous catheter in nursing homes, incomplete labeling, film wrapping, blood seepage, catheter discounting, non-standard film fixing, and incomplete information of extended care were 9.95% (21/211), 8.53% (18/211), 2.84% (6/211), 6.16% (13/211), 4.74% (10/211), 2.37% (5/211) after help, all lower than 50.57% (89/176), 43.18% (76/176), 14.20% (25/176), 25.57% (45/176), 18.18% (32/176), 11.93% (21/176) before help. The differences were statistically significant ( χ2 values were 14.00 to 77.81, all P<0.05). The incidence of medical adhesive related skin injury, catheter obstruction complications and unplanned extubation were 4.44% (4/90), 3.33% (3/90) and 2.22% (2/90), respectively, which were lower than 20.51% (16/78), 15.38% (12/78) and 11.54% (9/78) before help. The differences were statistically significant ( χ2=8.81, 6.06, 4.50, all P<0.05). Doctors′ satisfaction with nurses and patients′ satisfaction with nursing work were 96.43%(27/28) and 93.75%(45/48), respectively, both higher than 71.43%(20/28) and 72.73%(32/44) before help, and the differences were statistically significant respectively ( χ2=4.77, 5.97, both P<0.05). Conclusions:From the perspective of combination of medical care and nursing care, the maintenance and assistance of intravenous catheters by the team of intravenous therapy nurses in nursing hospitals can effectively reduce the incidence of central venous catheter complications and unplanned extubation, improve the maintenance ability of intravenous catheters of nurses in nursing hospitals, and help to improve the quality of nursing care in nursing hospitals.
