Cost-utility analysis of trastuzumab deruxtecan versus trastuzumab emtansine in the second-line treatment for HER2-positive metastatic breast cancer / 中国药房

OBJECTIVE To evaluate the cost-effectiveness of trastuzumab deruxtecan（T-DXd） versus trastuzumab emtansine （T-DM1） in the second-line treatment of HER2-positive metastatic breast cancer， and to provide a basis for the selection of clinical medication regimen and medical and health decisions. METHODS Based on the clinical trial DESTINY-Breast03， a partitioned survival model was constructed， with a cycle of 3 weeks as the simulation of patients’ lifetime. The incremental cost-effectiveness ratio （ICER） was calculated by using quality-adjusted life years （QALY） as output indicators， and sensitivity analysis was used to verify the robustness of the basic analysis results； the cost-effectiveness of the second-line treatment for HER2-positive metastatic breast cancer was compared between T-DXd and T-DM1. RESULTS Under the premise of taking 3 times China’s per capita gross domestic product （GDP） in 2022 as the willingness-to-pay threshold （257 094 yuan/QALY）， the T-DXd group also needed to pay more cost compared with T-DM1 group while obtaining incremental utility （0.69 QALYs）， and the ICER value was 1 850 478.40 yuan/QALY. The results of univariate sensitivity analysis showed that progression-free survival state utility value， T-DXd price， cost discount rate were factors that had a great influence on ICER value， but these parameters could not flip the basic analysis results within a reasonable range. In the probability sensitivity analysis， when the threshold of willingness-to-pay rose to 1 500 400 yuan/QALY， the probability of economic activity was 50% in the T-DXd regimen. The results of the scenario analysis also verified the robustness of the original research results. CONCLUSIONS Under the premise of 3 times China’s per capita GDP as the WTP threshold， compared with T-DM1， T-DXd is not cost-effective in the second-line treatment of HER2-positive metastatic breast cancer.

Long-term outcomes and influencing factors of idiopathic nephrotic syndrome in children / 中华肾脏病杂志

Pediatric idiopathic nephrotic syndrome (INS) is characterized by massive albuminuria, hypoproteinemia, edema and hyperlipidemia, with a long course and high probability of relapse and prolongation. Long-term complications caused by long-term usage of hormones and immunosuppressants in children with INS seriously affect their physical and mental health and quality of life. Most children with steroid-sensitive nephrotic syndrome can be cured before adulthood, while some of them relapse in adulthood. Long-term prognosis of children with steroid-resistant nephrotic syndrome is poor. There have been few studies in China followed the long-term outcomes and its related factors of children with INS over 10 years. The paper reviewed the literatures on the long-term outcomes of children with INS, including renal survival, growth, mental health, learning and work, marriage and fertility, disease recurrence and long-term related complications, to explore the factors related to the poor long-term outcomes of children with INS and to assist in clinical decision-making and follow-up management.

Intracranial activity of first-line immune checkpoint inhibitors combined with chemotherapy in advanced non-small cell lung cancer / 中华医学杂志(英文版)

BACKGROUND@#Immune checkpoint inhibitors (ICIs) are increasingly used as first-line therapy for patients with advanced non-small cell lung cancer (NSCLC) harboring no actionable mutations; however, data on their efficacy among patients presenting with intracranial lesions are limited. This study aimed to explore the efficacy and safety of ICIs combined with chemotherapy in advanced NSCLC patients with measurable brain metastasis at initial diagnosis.@*METHODS@#Our study retrospectively analyzed clinical data of a total of 211 patients diagnosed with driver gene mutation-negative advanced NSCLC with measurable, asymptomatic brain metastasis at baseline from Hunan Cancer Hospital between January 1, 2019 and September 30, 2021. The patients were stratified into two groups according to the first-line treatment regimen received: ICI combined with chemotherapy ( n = 102) or chemotherapy ( n = 109). Systemic and intracranial objective response rates (ORRs) and progression-free survival (PFS) were analyzed. Adverse events were also compared between the groups.@*RESULTS@#Compared with the chemotherapy-based regimen, the ICI-containing regimen was associated with a significantly higher intracranial (44.1% [45/102] vs . 28.4% [31/109], χ2 = 5.620, P = 0.013) and systemic (49.0% [50/102] vs . 33.9% [37/109], χ2 = 4.942, P = 0.019) ORRs and longer intracranial (11.0 months vs . 7.0 months, P <0.001) and systemic (9.0 months vs . 5.0 months, P <0.001) PFS. Multivariable analysis consistently revealed an independent association between receiving ICI plus platinum-based chemotherapy as a first-line regimen and prolonged intracranial PFS (hazard ratio [HR] = 0.52, 95% confidence interval [CI]: 0.37-0.73, P <0.001) and systemic PFS (HR = 0.48, 95% CI: 0.35-0.66, P <0.001). No unexpected serious adverse effects were observed.@*CONCLUSION@#Our study provides real-world clinical evidence that ICI combined with chemotherapy is a promising first-line treatment option for driver gene mutation-negative advanced NSCLC patients who present with brain metastasis at initial diagnosis.@*CLINICAL TRIAL REGISTRATION@#https://www.clinicaltrials.gov/ , OMESIA, NCT05129202.

Effects of Body Weight and Waist Circumference on Balance Function in Overweight and Obese Adults / 中山大学学报(医学科学版)

ObjectiveTo explore the effects of body weight and waist circumference on static and dynamic balance function in overweight and obese adults. MethodsParticipants （n=103） were selected by cluster random sampling from the Hypoglycemic Weight Loss Clinic of the Endocrinology Department of the Third Affiliated Hospital of Sun Yat-sen University. All participants were assessed for basic data collection， biochemical test， body weight， waist circumference and height measurement， static balance function assessed by balance error scoring system （BESS） and dynamic balance function assessed by functional reach test （FRT）. The BESS score and FRT distance of all participants were compared among groups according to different BMI grades and WC grades. Multivariate linear regression was used to analyze the influencing factors of participants' dynamic and static balance functions. Results① With the increase of BMI grading， the BESS score showed an upward trend， and the difference between groups was statistically significant （P = 0.004）. The BESS score of normal WC patients was lower than that of central obesity patients （P < 0.001）， which indicated that compared with normal BMI， overweight and obese people had poor dynamic and static balance ability； ② With the BMI grading， the FRT distance increased， showing a downward trend （P < 0.001）. The FRT distance in normal WC patients was significantly higher than that in central obesity patients （P < 0.001）， which indicated that the static and dynamic balance ability of central obesity patients was worse than that of normal WC patients； ③ In BMI overweight group， the FRT distance decreased significantly with the increase of WC （P = 0.02）. The results showed that under the condition of no difference in BMI， Compared with normal WC， the dynamic and static balance ability of central obese patients was worse； ④ The influence of BESS score on BMI（B=4.12，P =0.027， 95% CI=0.48-7.75）and WC（B = 3.47，P = 0.046， 95% CI = 0.07 - 6.88）was significant. The influence of FRT distance on BMI（B = -5.68，P = 0.001， 95% CI = -8.95 - 2.41）and WC（B = -4.71，P = 0.003， 95% CI = -7.83 to -1.61）was significant， which indicated that the static and dynamic balance ability of obese people was worse with the increase of BMI， and the ability of dynamic and static balance of central obesity was worse than that of normal WC. ConclusionWaist circumference is an independent factor affecting the dynamic and static balance function of overweight and obese people. Under similar BMI， the dynamic balance function of central obese people is worse than that of people with normal waist circumference， leading to higher risk of falling.

Objective:To study the effects of plan-do-check-action (PDCA) cycle in quality improvement of neonatal resuscitation.Methods:From 2016 to 2020, the clinical data of neonates born in our hospital were analyzed. Neonates born during 2016 to 2017 were pre-PDCA group and neonates born during 2018 to 2020 were post-PDCA group. PDCA quality improvement included step-by-step, high-frequency and low-dose training, strengthening teamwork and adding equipment.Results:A total of 7 728 live-birth neonates were delivered before PDCA with 319 cases (4.1%) of asphyxia. 10 174 live-birth neonates were delivered after PDCA with 422 cases (4.1%) of asphyxia. The asphyxia rates showed no significant difference between the two groups ( P>0.05). The incidences of severe asphyxia before and after PDCA were both 0.8% without significant difference ( P>0.05). The success rates of resuscitation for severe asphyxia before and after PDCA was 27.9% and 44.9%, respectively, and the differences were statistically significant ( P<0.05). The mortality rates within 7 d before and after PDCA were 0.5‰ and 0.1‰ respectively, without significant differences ( P>0.05). Conclusions:The implementation of PDCA cycle and step-by-step, high-frequency, low-dose neonatal resuscitation training can effectively improve the success rate of resuscitation in newborns with severe asphyxia.

Objective:To investigate the effects of alum ice nanoemulsion on VEGF and TGF-β1 in hypertrophic scar based on Notch signaling pathway.Methods:Totally 144 SD rats were divided into blank control group, model group, triamcinolone acetonide group and alum ice nanoemulsion low-, medium- and high-dose groups according to random number table method, with 24 rats in each group. Except for the blank control group, the rats in other groups were prepared with deep Ⅱ ° burn models. 24 hours after the successful modeling, the model group was given the same amount of normal saline, the rats in alum ice nanoemulsion low-, medium- and high-dose groups were given 8.15, 6.30 and 32.60 mg/ml alum ice nanoemulsion respectively, and the triamcinolone acetonide group was given triamcinolone acetonide twice a day, 0.2 ml each time, for 35 consecutive days. At 14, 21, 28 and 35 d, the collagen fiber surface density was calculated by VG staining. The protein expressions of vascular endothelial growth factor (VEGF), transforming growth factor-β1 (TGF-β1), Notch1 and Jagged1 were detected by Western Blot. The expressions of Notch1 mRNA and Jagged1 mRNA were detected by RT-PCR.Results:Compared with model group, triamcinolone acetonide and different doses of alum ice nanoemulsion groups could decrease collagen fiber surface density, protein expressions of VEGF, TGF-β1, Notch1, Jagged1 and mRNA expressions of Notch1, Jagged1 in different degrees ( P<0.05). Compared with the triamcinolone acetonide group, the collagen fiber surface density, protein expressions of VEGF, TGF-β1, Notch1 and Jagged1 and mRNA expressions of Notch1, Jagged1 in the alum ice nanoemulsion medium-dosage group decreased ( P<0.05). Conclusion:Alum ice nanoemulsion can inhibit hypertrophic scar formation, and its mechanism is related to down-regulating Notch signal pathway related molecules Notch1, Jagged1 protein and mRNA levels, and then down-regulating VEGF and TGF-β1 protein expressions.

Establishment and validation of clinical prediction model for steroid-resistant nephrotic syndrome in children / 中华儿科杂志

Objective: To identify the clinically relevant factors of steroid-resistant nephrotic syndrome (SSNS) in children and establish a predictive model followed by verifying its feasibility. Methods: A retrospective analysis was performed in a total of 111 children with nephrotic syndrome admitted to Children's Hospital of ShanXi from January 2016 to December 2021. The clinical data of general conditions, manifestations, laboratory tests, treatment, and prognosis were collected. According to the steroid response, patients were divided into SSNS and steroid resistant nephrotic syndrome (SRNS) group. Single factor Logistic regression analysis was used for comparison between the 2 groups, and variables with statistically significant differences were included in multivariate Logistic regression analysis. The multivariate Logistic regression analysis was used to identify the related variables of children with SRNS. The area under the receiver operating characteristic curve (ROC), the calibration curve and the clinical decision curve were used to evaluate its effectiveness of the variables. Results: Totally 111 children with nephrotic syndrome was composed of 66 boys and 45 girls, aged 3.2 (2.0, 6.6) years. There were 65 patients in the SSNS group and 46 in the SRNS group.Univariate Logistic regression analysis showed that the 6 variables, including erythrocyte sedimentation rate, 25-hydroxyvitamin D, suppressor T cells, D-dimer, fibrin degradation products, β2-microglobulin, had statistically significant differences between SSNS and SRNS groups (85 (52, 104) vs. 105 (85, 120) mm/1 h, 18 (12, 39) vs. 16 (12, 25) nmol/L, 0.23 (0.19, 0.27) vs. 0.25 (0.20, 0.31), 0.7 (0.6, 1.1) vs. 1.1 (0.9, 1.7) g/L, 3.1 (2.3, 4.1) vs. 3.3 (2.7, 5.8) g/L, 2.3 (1.9,2.8) vs. 3.0 (2.5, 3.7) g/L, χ2=3.73, -2.42, 2.24, 3.38, 2.24,3.93,all P<0.05), were included in the multivariate Logistic regression analysis. Finally, we found that 4 variables including erythrocyte sedimentation rate, suppressor T cells, D-dimer and β2-microglobulin (OR=1.02, 1.12, 25.61, 3.38, 95%CI 1.00-1.04, 1.03-1.22, 1.92-341.04, 1.65-6.94, all P<0.05) had significant correlation with SRNS. The optimal prediction model was selected. The ROC curve cut-off=0.38, with the sensitivity of 0.83, the specificity of 0.77 and area under curve of 0.87. The calibration curve showed that the predicted probability of SRNS group occurrence was in good agreement with the actual occurrence probability, χ2=9.12, P=0.426. The clinical decision curve showed good clinical applicability. The net benefit is up to 0.2. Make the nomogram. Conclusions: The prediction model based on the 4 identified risk factors including erythrocyte sedimentation rate, suppressor T cells, D-dimer and β2-microglobulin was suitable for the early diagnosis and prediction of SRNS in children. The prediction effect was promising in clinical application.

Value for combination of T1WI star -VIBE with TWIST -VIBE dynamic contrast -enhanced MRI in distinguishing lung nodules / 中南大学学报(医学版)

OBJECTIVES@#With the increasing detection rate of lung nodules, the qualitative problem of lung nodules has become one of the key clinical issues. This study aims to evaluate the value of combining dynamic contrast-enhanced (DCE) MRI based on time-resolved imaging with interleaved stochastic trajectories-volume interpolated breath hold examination (TWIST-VIBE) with T1 weighted free-breathing star-volumetric interpolated breath hold examination (T1WI star-VIBE) in identifying benign and malignant lung nodules.@*METHODS@#We retrospectively analyzed 79 adults with undetermined lung nodules before the operation. All nodules of patients included were classified into malignant nodules (n=58) and benign nodules (n=26) based on final diagnosis. The unenhanced T1WI-VIBE, the contrast-enhanced T1WI star-VIBE, and the DCE curve based on TWIST-VIBE were performed. The corresponding qualitative [wash-in time, wash-out time, time to peak (TTP), arrival time (AT), positive enhancement integral (PEI)] and quantitative parameters [volume transfer constant (Ktrans), interstitium-to-plasma rate constant (Kep), and fractional extracellular space volume (Ve)] were evaluated. Besides, the diagnostic efficacy (sensitivity and specificity) of enhanced CT and MRI were compared.@*RESULTS@#There were significant differences in unenhanced T1WI-VIBE hypo-intensity, and type of A, B, C DCE curve type between benign and malignant lung nodules (all P<0.001). Pulmonary malignant nodules had a shorter wash-out time than benign nodules (P=0.001), and the differences of the remaining parameters were not statistically significant (all P>0.05). After T1WI star-VIBE contrast-enhanced MRI, the image quality was further improved. Compared with enhanced CT scan, the sensitivity (82.76% vs 80.50%) and the specificity (69.23% vs 57.10%) based on MRI were higher than that of CT (both P<0.001).@*CONCLUSIONS@#T1WI star-VIBE and dynamic contrast-enhanced MRI based on TWIST-VIBE were helpful to improve the image resolution and provide more information for clinical differentiation between benign and malignant lung nodules.

Objective:To analyze the prevalence of malnutrition among human immunodeficiency virus-exposed uninfected (HEU) children and to identify the associated factors in Hunan Province.Methods:All children born to human immunodeficiency virus (HIV)-infected mothers retrieved from Information System of Prevention of Mother-to-Child Transmission of human immunodeficiency virus Management (IPMTCT) in Hunan Province between July 2013 and June 2019 were included. Information including maternal demographic characteristic, maternal comorbidities/complications, anti-retroviral therapy during pregnancy, anti-retroviral prophylaxis for children, birth weight, and disease during follow-up was collected. The length and weight of children at one, three, six, nine, 12 and 18 months of follow-up time points were detected, and the prevalences of stunting, underweight, wasting and malnutrition among HEU children were evaluated. The generalized estimating equation was used to fit the logistic regression model to analyze the associated factors for malnutrition.Results:A total of 656 HEU children were finally included. The prevalences of stunting, underweight, wasting, and malnutrition among HEU children were highest at one month of age, which were 11.9%(78/656), 9.1%(60/656), 7.0%(45/656) and 21.0%(138/656), respectively. Maternal comorbidities/complications (adjusted odds ratio (a OR)=2.30, 95% confidence interval ( CI) 1.48 to 3.58), mono/dual anti-retroviral therapy during pregnancy (a OR=2.38, 95% CI 1.54 to 3.68), birth weight <2 500 g (a OR=2.66, 95% CI 1.69 to 4.21) and disease during follow-up (a OR=1.73, 95% CI 1.10 to 2.70) were the risk factors for malnutrition among HEU children (all P<0.050). Both taking zidovudine (a OR=0.60, 95% CI 0.38 to 0.94) and nevirapine (a OR=0.31, 95% CI 0.18 to 0.52) for anti-retroviral prophylaxis were the protective factors for malnutrition among HEU children (both P<0.050). Conclusions:The prevalence of malnutrition among HEU children is high. The prevalence of malnutrition is affected by maternal comorbidities/complications, anti-retroviral therapy during pregnancy, and birth weight, diseases during follow-up and anti-retroviral prophylaxis for children.

Objective:To investigate the clinical effect of enteral nutrition support in the transformation therapy of advanced gastric cancer.Methods:Eighty-two patients with advanced gastric cancer treated by transformation in Zhejiang Provincial People′s Hospital from September 2019 to August 2021 were analyzed retrospectively. 41 patients in the observation group were treated with enteral nutrition support on the basis of routine transformation treatment; 41 patients in the control group received only routine transformation treatment. The nutritional related indexes such as prealbumin, total serum protein and albumin and immune related indexes such as CD4 + , CD8 + , CD4 + /CD8 + were detected before treatment and on the 7th day after the end of 3-cycle transformation treatment, and the above indexes and transformation success rate of the two groups were compared. Results:There was no significant difference in prealbumin, total serum protein, albumin, CD4 + , CD8 + , CD4 + /CD8 + between the two groups before treatment (all P>0.05). On the 7th day after three cycles of transformation treatment, the above indexes in the observation group were higher than those in the control group, with significant difference (all P<0.05). The success rate of transformation in the observation group was higher than that in the control group ( P<0.05). Conclusions:The rational use of enteral nutrition support in the transformation treatment of patients with advanced gastric cancer can significantly improve the nutritional status and immune function of patients, increase the tolerance to chemotherapy and improve the success rate of transformation.

Quantitative evaluation for payment policy of diagnosis-related groups in China based on PMC index model / 中国药房

OBJECTIVE To quantitatively evaluate the existing payment policies of diagnosis-related groups （DRGs）in China ， so as to provide reference for the formulation and improvement of policies. METHODS Totally 58 documents related to DRGs payment issued by the national and provincial medical security bureaus from 2017 to 2022 were processed by text mining method. PMC index evaluation model of DRGs payment policy was established. Nine typical DRGs payment policies were quantitatively evaluated and analyzed by 10 primary variables and 40 secondary variables. RESULTS Among the 9 policies，5 were excellent and 4 were acceptable. The average score of PMC index was 6.882. Generally ，there was still room for improvement because of the acceptable level. By comparing the two representative policies ，it was found that the main reasons was a lack of consideration in terms of supervision and management ，incentives and constraints when facing policy changes ，reason of the lower level of urban development. CONCLUSIONS Although DRGs payment policy in China is basically perfect ，there is still a lot of room for improvement in terms of extending the time limit of the policy ，summarizing and spreading the successful experience of pilot cities.

Research Progress of Immunotherapy for Non-small Cell Lung Cancer with Drive Gene Mutation / 中国肺癌杂志

Lung cancer is the most lethal malignancy around the world and non-small cell lung cancer (NSCLC) accounts for 80% of all cases. Most of the NSCLC patients has "driver gene mutations" and targeted therapy achieved a relatively good efficacy, but some patients progressed or relapsed after treatment. Previous studies demonstrated that immune checkpoint inhibitor could improve the prognosis of advanced-stage NSCLC and prolong the survival time. However, the efficacy of immune therapy varies in NSCLC patients with different immune and molecular features. The efficacy of immune therapy was controversial in NSCLC patients with driver gene mutation. The present review will summarize the immune characteristics of NSCLC patients with driver mutation and the directions of immunotherapy for patients with driver mutation.

Cost-utility analysis of sintilimab combined with chemotherapy in first-line treatment of advanced or recurrent non-small cell lung cancer / 中国药房

OBJECTIVE From the perspective o f China ’s h ealth service system ，to ev aluate the cost-effectiveness of sintilimab combined with chemotherapy in the first-line treatment of advanced or recurrent non-small cell lung cancer （NSCLC），so as to provide reference for the selection of clinical medication plan and medical and health decision-making. METHODS Based on the ORIENT-11 study data ，a partitioned survival model was established ，and the model period was 21 days to simulate the death of 99％ of the patients. Using quality-adjusted life years （QALY）as an output indicator ，the cost-effectiveness of sintilimab combined with chemotherapy （trial group ）versus chemotherapy alone （control group ）in the first-line treatment of advanced or recurrent NSCLC was evaluated. Cost and utility were discounted using 5％ discount rate ；sensitivity analysis and scenario analysis were used to verify the robustness of the underlying analysis results. RESULTS Under the premise that 3 times of the per capita gross domestic product （GDP）of China in 2020 was used as the threshold of willingness-to-pay （WTP），the patients in the trial group obtained more utility （0.482 QALY）and also spent nearly twice as much as the control group. The incremental cost-effectiveness ratio（ICER）was 334 974.41 yuan/QALY. Univariate sensitivity analysis showed that progression-free survival status utility value ， pemetrexed price ，utility discount rate ，cost discount rate and sintilimab price had a greater impact on ICER. The results of probability sensitivity analysis showed that when the WTP threshold was 3 times of China ’s per capita GDP in 2020，the probability of the trial group ’s plan being cost-effective was 6.5％. The results of the scenario analysis verified the robustness of the underlying analysis results. CONCLUSIONS On the premise of taking 3 times of China ’s per capita GDP in 2020 as the WTP threshold ， sintilimab combined with chemotherapy is not cost-effective for first-line treatment of advanced or recurrent NSCLC compared with chemotherapy alone.

SPSS 25.0 statistical software was used for analysis. Independent t test was used for the measurement data of normal distribution, Mann-Whitney U test was used for the measurement data of skewed distribution, and categorical variables were compared by chi-square test. Results:In the reading scores of MRI, the scores of the experimental group and the control group were (82.53 ± 5.72) points and (77.38 ± 6.14) points respectively, and the number of students in the experimental group whose reading scores were between 80-100 segment was 63.6% higher than that in the control group, with significant differences between the two groups ( P < 0.001), but without significant differences in theoretical average scores between the two groups ( P > 0.05). In addition, in the course evaluation, except for the index of learning burden, there were significant differences in other indexes between the experimental group and the control group ( P < 0.05). Conclusion:In the teaching of MRI, the application of the CBL helps non-imaging clinical professional postgraduates improve their MRI diagnostic thinking and independent reading ability.

Study on iodine nutrition and related influencing factors of children aged 8-10 in Wuhan / 中国学校卫生

Objective@#To understand the status of iodine nutrition and its related influencing factors of school-age children in Wuhan, so as to provide the basis for adjusting the strategies of IDD prevention and control.@*Methods@#In 5 districts of Wuhan (Hongshan, Hanyang, Hannan, Jiangxia, Dongxihu), non-boarding students aged 8-10 years old were selected from each of the five sample areas in the east, west, south, north and middle. Samples of urine and the cooking salt from their home were randornly colleted among children. Height, weight measurement and a self-administered questionnaire were conducted at the same time. A total of 942 valid questionnaires were collected, including 484 boys and 458 girls.@*Results@#The median of iodine content of children s household salt was 23.20 mg/kg, the median of urinary iodine of children in the city was 251.00 μg/L. Children s random urine iodine concentration was related to gender, whether kelp was consumed the day before the survey, the frequency of consuming milk, and whether they received radiological examinations(P<0.05). Male (OR=1.38, 95%CI=1.04-1.82), consumption of kelp the day before the survey (OR=1.67,95%CI=1.13-2.47) and radiological examination (OR=1.26,95%CI=1.05-1.52) were risk factors for children with urinary iodine concentration higher than the upper limit of the appropriate value(P<0.05). The awareness rate of children s iodine deficiency disease prevention knowledge in Wuhan was 69.64%.@*Conclusion@#The iodine nutritional status of children aged 8-10 years in Wuhan was higher than the appropriate level recommended by international organizations. The random urine iodine concentration of children was affected by many factors and the awareness rate of children s iodine deficiency disease knowledge in Wuhan was low. Therefore, health education for children and residents on iodine deficiency disorders should be strengthened, and they should be properly guided and intervened to ensure that iodine deficiency is prevented while iodine excess is avoided.

Comparison of clinical utility of 18F-FAPI-42 and 18F-FDG PET/CT imaging in the diagnosis of newly diagnosed lung cancer / 中华核医学与分子影像杂志

Objective:To compare the clinical utility of 18F-fibroblast activating protein inhibitor (FAPI)-42 and 18F-fluorodeoxyglucose (FDG) PET/CT imaging in newly diagnosed lung cancer patients. Methods:From May 2020 to September 2021, the images of 43 lung cancer patients (32 males, 11 females, age: 37-80 years) who pathologically confirmed and received 18F-FDG and 18F-FAPI-42 PET/CT within 2 weeks in the First Affiliated Hospital of Guangzhou Medical University were prospectively analyzed. The maximum standardized uptake value (SUV max) of 18F-FDG and 18F-FAPI-42 and the number of lesions detected by 2 imaging methods were compared by using paired t test and Wilcoxon rank sum test. Results:The 43 newly diagnosed lung cancer patients included 35 adenocarcinoma, 2 squamous cell carcinoma, 4 small cell lung cancer, and 2 high-grade neuroendocrine tumors. 18F-FAPI-42 had a very high tumor uptake (SUV max: 12.24±3.97) and lesion detection rate (positive rate: 100%(37/37)) in primary lung adenocarcinoma and squamous cell carcinoma. The uptake of 18F-FAPI-42 in lymph node (10.13±5.43), pleura (6.75(4.96, 8.58)) and bone lesion (7.18(4.33, 9.66)) were significantly higher than those of 18F-FDG (6.35±3.30, 2.69(1.81, 5.00), 4.38(2.96, 6.36); t=12.19, z values: 5.47, 5.79, all P<0.001). In lung adenocarcinoma and squamous cell carcinoma, although the uptake of 18F-FAPI-42 in brain metastases was significantly lower than that of 18F-FDG (0.72(0.15, 1.82) vs 6.53(4.65, 9.34); z=6.42, P<0.001), the tumor/background (T/B) ratio was significantly higher than that of 18F-FDG (3.54(1.15, 14.88) vs 0.96(0.77, 1.04); z=6.05, P<0.001). In lung adenocarcinoma and squamous cell carcinoma, the number of lesions detected by 18F-FAPI-42 PET/CT was significantly more than that of 18F-FDG (lymph node: 6.0(2.3, 11.5) vs 4.5(2.0, 10.8); brain: 2.0(1.0, 3.0) vs 0.0(0.0, 0.0); pleura: 6.0(2.8, 10.0) vs 4.0(0.8, 5.5); z values: 2.16, 3.10, 2.04, all P<0.05). However, in high-grade neuroendocrine tumors and small cell lung cancer, the SUV max of 18F-FAPI-42 in primary lesions (8.05±2.60), lymph node lesions (5.98±2.21) and brain lesions (0.44(0.13, 0.82)) were lower than those of 18F-FDG (16.28±5.17, 12.30±5.47, 4.94(4.84, 6.25); t values: 3.58, 7.52, z=3.06, all P<0.05). Conclusions:In lung adenocarcinoma and squamous cell carcinoma, 18F-FAPI-42 has a very high tumor uptake and lesion detection rate in primary tumor. In addition, compared with 18F-FDG PET/CT, 18F-FAPI-42 PET/CT shows clearer tumor contours and more lesions. Therefore, 18F-FAPI-42 is more suitable for preliminary staging of lung adenocarcinoma and squamous cell carcinoma than 18F-FDG, while the opposite is true in small cell lung cancer and high-grade neuroendocrine tumors.
