OBJECTIVE To compare the long-term cost-effectiveness of gonadotrophin-releasing hormone analogue （GnRHa） combined with recombinant human growth hormone （rhGH） （combination therapy regimen） versus GnRHa monotherapy （monotherapy regimen） in the treatment of central precocious puberty （CPP）. METHODS From the societal perspective and based on a real-world study conducted at West China Second Hospital of Sichuan University， the cost-effectiveness analysis was performed to compare the long-term cost-effectiveness of two pharmacotherapy regimens for CPP girls， with final height as outcome indexes， using per capita disposable income of rural residents and urban residents （20 133-49 283 yuan） in 2022 as the social willing-to-pay （WTP） threshold. The robustness of the basic analysis result was verified by using one-way sensitivity analysis and probability sensitivity analysis， and the cost-effectiveness of different combinations of long-acting preparations was compared using scenario analysis. RESULTS The basic analysis result showed that the combination therapy regimen required an additional cost of 25 193.49 yuan for every one-centimeter improvement in the final height of girls with CPP compared with the monotherapy regimen， which was not cost-effective for residents in rural areas， but it was cost-effective for residents in urban areas. One-way sensitivity analysis showed that the uncertain factors with potential impacts on the results were， in order， the price of rhGH， the final height of pediatric patients in the combination therapy regimen group， the course of rhGH in the combination therapy regimen group， and the final height of pediatric patients in the monotherapy regimen group. Probabilistic sensitivity analysis indicated that the probability of the combination therapy regimen being cost-effective was higher than that of the monotherapy regimen when WTP was more than 26 010 yuan/cm. When GnRHa long-acting preparation was used for intramuscular injection every 3 months， the combination therapy regimen was not cost-effective for rural residents， but was cost-effective for urban residents； when rhGH long-acting preparation was injected subcutaneously once a week， the combination therapy regimen was not cost-effective for residents in both rural areas and urban areas. CONCLUSIONS The combination of GnRHa and rhGH is only recommended for CPP children with better affordability to improve final height. The benefits， risks， and affordability of treatment should be comprehensively considered before the decisions on pharmacotherapy， to avoid abuse of rhGH due to the blind pursuit of height growth.

Elderly end-of-life patients often experience distress due to being caught in dilemmas of contemplation and decision-making. Narrative wills， grounded in life values and premised on respecting individual wishes and needs， present an individual’s unique life story through narrative forms， conveying their overall experience， interpretation of meaning， and understanding of life. They are preserved and passed on in a way that meets individual expectations， thereby promoting human exploration， reflection， and growth regarding the meaning of life through interpersonal interactions that transcend space and time. This paper explored the concept of narrative wills among elderly end-of-life patients， the ethical value and ethical principles of narrative wills， and the moral and ethical risks. It also provided specific ethical interpretations， assisting in the application and development of narrative wills in elderly end-of-life patients.

The coronary artery disease is a frequent severe disease of cardiovascular system in recent years. Meanwhile, lung cancer, with its high morbidity and mortality, is the most frequent malignant tumor of respiratory system in the world. Clinical studies have shown that the incidence of coronary artery disease and lung cancer is high throughout the year, and comorbidities are becoming more common, especially in elderly patients. The incidence of lung cancer and coronary heart disease may be related. This article summarizes the common risk factors (smoking and environmental pollution, fibrinogen, estrogen, and age), and treatment (surgical treatment, neoadjuvant therapy, and targeted therapy) progress of the two diseases, providing a theoretical basis for clinical prevention and treatment.

Purpose To establish a nomogram based on conventional ultrasound combined with contrast-enhanced ultrasound(CEUS)for predicting the probability of cervical central lymph node metastasis(CLNM)in clinical lymph node-negative(CN0)papillary thyroid carcinoma(PTC)patients.Materials and Methods A retrospective study was performed on 359 patients with single CN0 PTC,all of whom underwent thyroid surgery and prophylactic central compartment neck dissection in the First Affiliated Hospital of Shihezi University from September 2015 to March 2022.According to the postoperative pathological results,there were 116 cases with CLNM(+)and other 243 cases with CLNM(-).The indicators of gender,age,conventional ultrasound and CEUS were recorded,and multivariate stepwise Logistic regression was performed to screen out risk predictors to construct prediction models for CLNM in CN0 PTC.The receiver operating characteristic curves of prediction models were drawn,and the area under the curve(AUC)was further compared.The preferable prediction model was selected to establish the risk probability nomogram,and the prediction performance and clinical applicability of the nomogram model were assessed.Results Multivariate analysis showed that gender,age,the maximum diameter of nodule,capsule invasion and enhancement pattern on CEUS were risk factors for CLNM in CN0 PTC(all P<0.05).The AUC of prediction model 1 including the above five indicators was 0.753,and the AUC of prediction model 2 excluding CEUS indicator was 0.704.There were statistically significant difference in AUCs between the two models(Z=2.473,P=0.013).Prediction model 1 was selected to construct a risk probability nomogram for predicting CLNM in CN0 PTC.The nomogram had a C-index of 0.753 and showed well consistency on the calibration curve.Clinical decision curve analysis indicated that the nomogram could achieve ideal net benefit when the threshold probability was between 10.7%to 81.5%.Conclusion Gender,age,the maximum diameter of nodule,capsule invasion and enhancement pattern on CEUS may be the risk predictors for CLNM in CN0 PTC.The nomogram model based on the above indicators can predict the probability of CLNM effectively,and the CEUS indicators can substantially improve the prediction performance of the model.

Objective:To detect pathogenic mutation in a Chinese family affected with isolated bilateral microtia.Methods:During 2022 June to December, one Chinese Han family with non-syndromic bilateral microtia was recruited at the First Hospital of Shanxi Medical University. The clinical data and peripheral blood samples were collected from the family members. Whole genome sequencing (WGS) was performed in the proband to screen all candidate variants. Quantitative PCR was applied to identify the candidate copy number variation (CNV) among the proband, the unaffected wife and the affected son to demonstrate the association between candidate variant and phenotype.Results:The patients in the family had non-syndromic bilateral concha-type microtia. WGS detected the duplication in the intergenic region of HMX1 and CPZ gene in the proband, which involved the evolutionarily conserved region (ECR). Both the proband and his affected son carried the CNV, while his unaffected wife did not have this variation.Conclusion:Duplications involving the long range HMX1 enhancer ECR are associated with the bilateral concha-type microtia in this family.

With the improvement of living standards,at least a quarter of the global population has non-alcoholic fatty liver disease(NAFLD),which is considered to be an important cause of the increased incidence of hepatocellular carcinoma(HCC)in recent years.Finding effective means for disease prevention and/or treatment largely relies on deep understanding of the mechanisms of NAFLD to HCC,which needs to con-struct the stable experimental models to simulate the entire process of disease progression in human NAFLD-HCC.This paper summarizes the animal models which are currently used to study NAFLD-HCC and their ad-vantages and disadvantages,in order to provide a basis for the selection of animal models and accelerate the transition from basic study to clinical study.

Objective:To investigate the effects of dexmedetomidine and urapidil on postoperative extubation stress response, postoperative shivering, and cerebral oxygen metabolism in patients with hypertensive intracerebral hemorrhage.Methods:A total of 120 patients with hypertensive intracerebral hemorrhage admitted to the Seventh People′s Hospital of Hebei Province from January 2021 to December 2022 were selected as the research subjects. They were randomly divided into an observation group (60 cases) and a control group (60 cases) according to the random number table method. All patients underwent intracranial hematoma removal surgery under general anesthesia combined with bone flap decompression surgery for treatment. The observation group patients received sedation and analgesia with dexmedetomidine and urapidil after surgery, while the control group patients received sedation and analgesia with dexmedetomidine after surgery. The differences in vital signs, stress indicators, cerebral oxygen and cerebral glucose metabolism, and adverse reactions between two groups of patients were compared.Results:There was no statistically significant difference in heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and bispectral index (BIS) between the two groups after entering the room (T 0) and before anesthesia medication (T 1) (all P>0.05). The HR, SBP, DBP, and BIS of the observation group were significantly lower than those of the control group at extubation (T 2), immediately after extubation (T 3), 1 minute after extubation (T 4), and 3 minutes after extubation (T 5), and the differences were statistically significant (all P<0.05). There was no statistically significant difference in various stress indicators between the two groups of patients at T 0 (all P>0.05), while the stress indicators of the observation group were significantly lower than those of the control group at T 5 (all P<0.05). There was no statistically significant difference in the cerebral oxygen uptake rate (CERO 2) and cerebral arteriovenous blood glucose difference (AVDG) between the two groups of patients at T 0 (all P>0.05), while the CERO 2 and AVDG in the observation group at T 5 were significantly higher than those in the control group (all P<0.05). There was no statistically significant difference in the incidence of hypoxemia, hypotension, and bradycardia between the two groups of patients after surgery (all P>0.05). The incidence of postoperative shivering in the observation group was lower than that in the control group ( P<0.05). The Glasgow Coma Index of both groups of patients after surgery was higher than that before surgery (all P<0.05), and there was no statistically significant difference in Glasgow Coma Index between the two groups before and after surgery (all P>0.05). Conclusions:Dexmedetomidine and Urapidil have significant improvement effects on postoperative extubation stress response, postoperative shivering, and cerebral oxygen metabolism in patients with hypertensive intracerebral hemorrhage. It is recommended to promote them clinically.

OBJECTIVE To evaluate the effectiveness， safety， economy， innovation， suitability and accessibility of recombinant Mycobacterium tuberculosis fusion protein （EC）， and to provide evidence for selecting skin detection methods for tuberculosis infection diagnosis and auxiliary diagnosis of tuberculosis. METHODS The effectiveness and safety of EC compared with purified protein derivative of tuberculin （TB-PPD） were analyzed by the method of systematic review. Cost minimization analysis， cost-effectiveness analysis and cost-utility analysis were used to evaluate the short-term economy of EC compared with TB-PPD， and cost-utility analysis was used to evaluate the long-term economy. The evaluation dimensions of innovation， suitability and accessibility were determined by systematic review and improved Delphi expert consultation， and the comprehensive score of EC and TB-PPD in each dimension were calculated by the weight of each indicator. RESULTS The scores of effectiveness， safety， economy， innovation and suitability of EC were all higher than those of TB-PPD. The affordability scores of the two drugs were consistent， while the availability score of EC was lower than those of TB-PPD. After considering dimensions and index weight， the scores of effectiveness， safety， economy， innovation， suitability， accessibility and the comprehensive score of EC were all higher than those of TB-PPD. CONCLUSIONS Compared with TB-PPD， EC performs better in all dimensions of effectiveness， safety， economy， innovation， suitability and accessibility. However， it is worth noting that EC should further improve its availability in the dimension of accessibility.
