OBJECTIVE To evaluate the cost-utiliby of capivasertib combined with fulvestrant for the second-line treatment of hormone receptor-positive/human epidermal growth factor receptor-2-negative （HR+/HER2－） advanced breast cancer from the perspective of the Chinese healthcare system. METHODS A partitioned survival model was constructed using clinical data from the CAPItello-291 trial. Costs and quality-adjusted life years （QALYs） were used as the output indicators of the model， and the incremental cost-effectiveness ratio （ICER） was used as the evaluation indicator of the model. Using three times the per capita gross domestic product （GDP） of China in 2024 as the willingness-to-pay threshold （WTP）， this study analyzed the cost-utility of capivasertib combined with fulvestrant versus fulvestrant monotherapy in the treatment of HR+/HER2－ advanced breast cancer， and conducted sensitivity analysis and scenario analysis under conditions where the price of capivasertib was reduced by 50%， 60%， 70% and 95%， respectively. RESULTS The results of the basic analysis showed that compared with the fulvestrant monotherapy regimen， the ICER of capivasertib combined with fulvestrant was 843 038.46 yuan/QALY， which was higher than the WTP（287 247 yuan/QALY）. The one-way sensitivity analysis revealed that the top three factors with the most substantial influence on ICER were the utility value in the progression disease state， the price of capivasertib， and the utility value inthe progression free survival state. Probabilistic sensitivity analysis demonstrated the robustness of the basic analysis results. Scenario analysis revealed that even if the price of capivasertib were reduced by 95%， capivasertib combined with fulvestrant did not exhibit cost-effectiveness at the current WTP. CONCLUSION At a WTP of three times China’s GDP per capita in 2024， compared to fulvestrant monotherapy， capivasertib combined with fulvestrant as the second-line treatment for HR+/ HER2－ advanced breast cancer is not cost-effective.

Background::Mild traumatic brain injury (mTBI) is a common neurological trauma that can lead to cognitive impairment. The sirtuin-1 (SIRT-1)/peroxisome proliferator-activated receptor gamma coactivator-1α (PGC-1α) pathway has been reported to have neuroprotective effects in rats with craniocerebral injury. We evaluated potential mechanisms underlying electroacupuncture-mediated recovery of cognitive function after mTBI, focusing on the SIRT-1/PGC-1α/mitochondrial pathway.Methods::We included forty 6-week-old male Sprague-Dawley rats in this study. Rats were randomly divided into four groups: controlled cortical impactor (CCI, n = 10), sham operation (sham, n = 10), electroacupuncture-treated CCI (CCI+EA, n = 10), and electroacupuncture-treated sham (sham+EA, n = 10) group. Randomization was performed by assigning a random number to each rat and using a random number table. The mTBI rat model was established using a controllable cortical impactor. Electroacupuncture therapy was performed on the back of rats, by inserting acupuncture needles to the specific acupoints and setting appropriate parameters for treatment. We evaluated spatial learning and memory functions with the Morris water maze test. We performed quantitative real-time polymerase chain reaction (qRT-PCR), western blotting, adenosine triphosphate (ATP) determination, and mitochondrial respiratory chain complex I (MRCC I) determination on rat hippocampal tissue. We analyzed SIRT-1/PGC-1α expression levels and the results of mitochondrial function assays, and compared differences between groups using bilateral Student’s t-tests. Results::Compared with the sham group, SIRT-1/PGC-1α expression was downregulated in the hippocampus of CCI group ( P <0.01). Although this expression was upregulated following electroacupuncture, it did not reach the levels observed in the sham group ( P <0.05). Compared with the sham group, MRCC I and ATP levels in the CCI group were significantly reduced, and increased after electroacupuncture ( P <0.01). In the Morris water maze, electroacupuncture reduced the incubation period of rats and increased average speed and number of crossing platforms ( P <0.05). Conclusion::Electroacupuncture may improve cognitive function in the mTBI rat model by regulating the SIRT-1/PGC-1α/mitochondrial pathway.

Objective To discuss the clinical application of coronary CT angiography(CCTA)-derived fractional flow reserve(CT-FFR)in evaluating the risk stratification of the coronary artery stenosis and atherosclerotic plaque quantitative parameters.Methods A total of 122 patients,who received CCTA examination at the Xuzhou Municipal Central Hospital of China,were enrolled in this study.The patients were divided into non-ischemia group(CT-FFR＞0.8,n=66)and ischemia group(CT-FFR0.8,n=56).The characteristics of atherosclerotic plaque were compared between the two groups.Logistic regression analysis was used to analyze the correlation between plaque characteristics and ischemic lesions.Results There were 218 vessels having a CT-FFR＞0.8 and 174 vessels having a CT-FFR ≤0.8.Statistically significant differences in the total plaque volume,calcified plaque volume,plaque length,and stenosis ratio＞50％existed between the two groups(all P＜0.05).Logistic regression analysis indicated that the total plaque volume,calcified plaque volume,plaque length,and stenosis ratio＞50％were the risk factors for myocardial ischemia.Conclusion CT-FFR can be used for the risk stratification of coronary stenosis and atherosclerotic plaque characteristics,which can evaluate the local myocardial blood supply condition from the anatomical stenosis and functional level so as to optimize the diagnosis and treatment measures.

Abstract: Objective　To compare and analyze the clinical characteristics, diagnosis, and treatment of different subtypes of severe influenza in neonates to provide a reference for the diagnosis and treatment of neonatal severe influenza. Methods A cohort of 40 neonates with severe influenza who were hospitalized in the neonatology ward of Children's Hospital Affiliated to Zhengzhou University between January 2019 to December 2023 were selected and divided into two groups based on the virus subtype: influenza A (n=23) and influenza B (n=17). A retrospective analysis was conducted to compare general information, clinical manifestations, auxiliary examinations, complications, and treatment outcomes of neonates with severe influenza A and B infection. Results The number of days of hospitalization was longer in cases of influenza A than that of influenza B. The proportion of neonates with severe influenza A who exhibited fever was higher than that for influenza B, and a higher percentage of those with fever had peak temperatures ranging from 38.1 ℃ to 39 ℃. Gastrointestinal symptoms, including vomiting and diarrhea leading to dehydration, were more evident in severe influenza B cases. The proportion of influenza A cases with abnormal creatine kinase-MB isoenzyme levels (>25 U/L) was higher than that of influenza B, and the differences were statistically significant (P<0.05). There were no significant differences between the two types of influenza in other clinical manifestations, the incidence of pneumonia/respiratory failure complications, peripheral blood leukocyte count and classifications, the proportion of abnormal aspartate aminotransferase (AST) (>40 U/L), alanine aminotransferase (ALT) (>40 U/L), and creatine kinase (CK) (>200 U/L), and lactate dehydrogenase (LDH) values (all P>0.05). In terms of treatment, neonates treated with Oseltamivir within 48 hours of onset mainly suffered from influenza A. Among those treated with Oseltamivir, the proportion of influenza A cases whose body temperature returned to normal within 24 hours was relatively higher, whereas, for those whose temperature returned to normal within 24-72 hours, the proportion was relatively higher in influenza B cases. These differences were statistically significant (all P<0.05). Conclusions Severe neonatal influenza usually occurs in winter and spring. After severe infection, fever is more obvious in neonates with influenza A, which is more likely to cause myocardial cell damage. Neonates with influenza A can be treated with Oseltamivir earlier and return to normal body temperature faster than those with influenza B after Oseltamivir treatment. Gastrointestinal symptoms are more common in neonates with severe influenza B.

Objective:To construct a rehabilitation scheme for patients with elbow joint injury based on the theoretical framework of International Classification of Functioning, Disability and Health (ICF) and to explore its application effect.Methods:The simple random sampling method was used to select 154 patients with elbow joint injuries who were treated in Zhengzhou Orthopedic Hospital from January 2019 to June 2021. According to the random number table method, they were divided into the control group and the observation group, with 77 cases in each group. The control group adopted the conventional rehabilitation model, while the observation group adopted the rehabilitation program based on the ICF theoretical framework. The elbow joint function, recovery and satisfaction were compared between the two groups before and after the intervention.Results:Before the intervention, there was no statistically significant difference in the pain, function, range of motion, muscle strength, flexion deformity, stability, score reduction items and total score between the two groups ( P>0.05) . After the intervention, the pain, function, range of motion, muscle strength, flexion deformity, stability scores and total scores of the two groups of patients were all higher than those before the intervention, and the scores of score reduction items were lower than those before the intervention ( P<0.05) . After intervention, the pain, function, range of motion, muscle strength, flexion deformity, stability scores and total scores of the observation group were higher than those of the control group, and the scores of score reduction items were lower than those of the control group ( P<0.05) . The disappearance time of pain and swelling in the observation group were shorter than those in the control group ( P<0.05) . The total satisfaction of the observation group was higher than that of the control group ( P<0.05) . Conclusions:The rehabilitation program for patients with elbow joint injury based on the ICF theoretical framework can improve the elbow function and satisfaction of patients and speed up the rehabilitation.

Results Among the 120 patients with liver cirrhosis, Child-Pugh A grade was in 39 cases, Child-Pugh B grade in 28 cases, and Child-Pugh C grade in 53 cases. The LSM in Child-Pugh B grade patients and C grade patients were significantly higher than that in Child-Pugh A grade patients: (20.2 ± 1.1) and (30.8 ± 1.2) kPa vs. (15.7 ± 1.4) kPa, the LSM in Child-Pugh C grade patients was significantly higher than that in Child-Pugh B grade patients, and there were statistical differences (P<0.05). Among the 103 patients with hepatitis-B virus-related cirrhosis, Child-Pugh A grade was in 33 cases, Child-Pugh B grade in 24 cases, and Child-Pugh C grade in 46 cases. The LSM in Child-Pugh B grade patients and C grade patients were significantly higher than that in Child-Pugh A grade patients: (18.7 ± 0.9) and (26.9 ± 0.6) kPa vs. (12.6 ± 1.7) kPa, the LSM in Child-Pugh C grade patients was significantly higher than that in Child-Pugh B grade patients, and there were statistical difference (P<0.05). Among the 57 patients associated ascites, Child-Pugh B grade was in 11 cases, and Child-Pugh C grade in 46 cases. The LSM in Child-Pugh C grade patients was significantly higher than that in Child-Pugh B grade patients:(42.3 ± 1.4) kPa vs. (35.1 ± 1.0) kPa, and there was statistical difference (P<0.05). Among the 103 patients with hepatitis-B virus-related cirrhosis, associated ascites was in 49 cases, Child-Pugh B grade was in 10 cases, and Child-Pugh C grade in 39 cases. The LSM in Child-Pugh C grade patients was significantly higher than that in Child-Pugh B grade patients: (40.6 ± 0.9) kPa vs. (33.2 ± 1.5) kPa, and there was statistical difference (P<0.05). Conclusions The LSM values of patients with liver cirrhosis are higher with the elevation of liver function Child-Pugh grade. There is a correlation between LSM values and Child-Pugh scores. The LSM can partly evaluate the severity of liver disease in patients with liver fibrosis.

Objective To estimate the clinical effect of fuzhenghuayu capsule in treatment of early hepatocirrhosis by liver instantaneous elastic imaging. Methods Eighty patients with early hepatocirrhosis were divided into experiment group and control group according to the treatment method with 40 cases each. All the patients in 2 groups were given the same antiviral treatment with entecavir dispersible tablets, and the patients in experiment group combined with fuzhenghuayu capsule. All treatment lasted for 6 months. The liver stiffness measurement (LSM) was measured before treatment and 1, 3 and 6 months after treatment by liver instantaneous elasticity imaging. The serum hyaluronic acid was measured, and the Child-Pugh score was evaluated at the same time. Results The LSM, hyaluronic acid and Child-Pugh scores 6 months after treatment in experiment group were significantly lower than those in control group:(19.3 ± 0.9) kPa vs. (29.6 ± 1.3) kPa, (215.6 ± 59.3)μg/L vs. (344.4 ± 39.6)μg/L and (2.1 ± 1.3) scores vs. (3.9 ± 0.9) scores, and there were statistical differences (P<0.05). No obvious adverse reactions related to the use of fuzhenghuayu capsule were found during the course of treatment. Conclusions Liver instantaneous elasticity imaging can be used to evaluate and monitor early hepatocirrhosis. Fuzhenghuayu capsule on patients with early hepatocirrhosis has a certain degree of curative effect.
