Investigator initiated trial （IIT） represents a primary format for clinical research in traditional Chinese medicine （TCM）. As key implementation sites for TCM-based IIT targeting malignant tumors， western medicine institutions often face unique challenges in conducting such studies， which limit their feasibility and standardization. This paper reviews the registration status of TCM-based IIT for malignancies conducted in western medical institutions and analyzes key difficulties， including complex project initiation and management processes， limited TCM knowledge and skills among western medicine physicians， and relatively low patient acceptance of TCM. From a practical perspective， the study proposes several optimization strategies. These include improving the review and management mechanisms of TCM-related IIT within western medical institutions， establishing multidisciplinary clinical research teams that integrate TCM and western medicine， and enhancing investigators' training in TCM theory and clinical skills. Additionally， the study suggests standardizing IIT operational procedures， objectifying the collection of TCM diagnostic information， refining subject recruitment methods， and increasing TCM involvement in patient follow-up and management. These investigator-oriented， TCM-featured， and operable strategies aim to promote the high-quality development of TCM-based IIT in western medicine institutions and enhance the clinical application of TCM.

Objective To investigate the correlation of solute carrier protein 17 family member 1 (SLC17A1) gene single nucleotide polymorphisms (SNPs) and susceptibility to hyperuricemia (HUA) in automotive manufacturing workers. Methods A total of 192 Han male workers diagnosed with HUA were selected as the case group, 192 Han male workers without HUA from the same enterprises were selected as the control group. These workers were determined by the matching factor of age, total length of service, and body mass index by the 1∶1 case-control study method. Peripheral venous blood from the workers was collected for DNA extraction. Two SNPs of SLC17A1 were genotyped by MassArray system. Results The gene frequency distributions of SLC17A1 rs2096386 and rs1183201 of workers in the control group were in consistent with the Hardy-Weinberg equilibrium test (both P>0.05). The allele frequency distribution of rs2096386, and the genotype and allele frequency distribution of rs1183201 were significantly different between workers in the two groups (all P<0.05). There was no significant difference in genotype frequency distribution of rs2096386 between workers in the two groups (P>0.05). The results of conditional logistic regression analysis showed that workers with G allele at rs2096386 increased the risk of HUA [odds ratio (OR)=1.43, 95% confidence interval (CI)=1.01-2.04], workers with T allele at rs1183201 increased the risk of HUA (OR=2.03, 95%CI =1.29-3.19), after adjusting for confounding factors such as serum creatinine, blood urea nitrogen, alanin aminotransferase and aspartate aminotransferase. While workers with TA and TA+AA genotypes at rs1183201 had a lower risk of HUA than those with TT genotype (OR=0.51, 95%CI =0.30-0.85; OR=0.50, 95%CI =0.30-0.83), workers with TA genotype at rs1183201 had a lower risk of HUA than those with TT+AA genotype (OR=0.53, 95%CI =0.32-0.88). Conclusion The polymorphisms at rs2096386 and rs1183201 of SLC17A1 gene may be correlated with HUA susceptibility among automobile manufacturing workers in Guangzhou City.

ObjectiveTo investigate the attenuating effect of Dioscoreae Bulbiferae Rhizoma（DBR） processed with Phaseoli Radiati Semen（PRS） juice， and explore the attenuating mechanism based on ferroptosis of the main toxic target organ. MethodSixty male ICR mice were randomly divided into blank group， DBR group， water roasted DBR group（hereinafter referred to as water group）， PRS juice-roasted DBR group 1（DBR-PRS 10∶1， stuffy moistening for 40 min， stir-fried at 130 ℃ for 18 min， hereinafter referred to as group 1）， PRS juice-roasted DBR group 2（DBR-PRS 10∶1， stuffy moistening for 80 min， stir-fried at 100 ℃ for 14 min， hereinafter referred to as group 2）， PRS juice-roasted DBR group 3（DBR-PRS=20∶3， stuffy moistening for 40 min， stir-fried at 160 ℃ for 14 min， hereinafter referred to as group 3）. The raw and processed groups of DBR were gavaged with their corresponding 95% ethanol extract at a dose of 3 g·kg^-1·d^-1， while the blank group was gavaged with an equal volume of 0.5% sodium carboxymethyl cellulose， once a day for 14 consecutive days. Hematoxylin-eosin（HE） staining was used to observe the histopathological changes of mouse liver. Alanine aminotransferase（ALT） and aspartate aminotransferase（AST） levels in serum， as well as malondialdehyde（MDA）， ferrous ions（Fe²⁺）， reduced glutathione（GSH） and superoxide dismutase（SOD） levels in liver tissue were detected by the biochemical detection. Western blot was used to detect the expression of iron key proteins such as ferritin heavy chain 1（FTH1） and glutathione peroxidase 4（GPX4）. ResultHE staining results showed that the liver tissue structure of the blank group was clear， the morphology of hepatocytes was normal， the cytoplasms of hepatocytes in the DBR group and water group were loose and vacuolar， with obvious pathological damages， and the pathologic damages of mice in the group 1-3 were significantly improved. Compared with the blank group， the levels of ALT， AST， MDA and Fe²⁺ in mice from the DBR group were significantly increased（P<0.01）， while GSH and SOD levels were significantly reduced（P<0.01）， and the protein expression levels of FTH1 and GPX4 were significantly decreased（P<0.01）. Compared with the DBR group， the ALT， AST，MDA and Fe²⁺ levels of mice in the group 1-3 were significantly reduced（P<0.05， P<0.01）， the GSH and SOD levels and the protein expression levels of FTH1 and GPX4 were significantly increased（P<0.01）. Compared with the water group， the AST and MDA levels of mice in the group 1-3 were significantly reduced（P<0.05， P<0.01）， the SOD level significantly increased（P<0.05， P<0.01）， the FTH1 protein expression significantly increased（P<0.01）， and the serum ALT level of mice in the group 2-3 significantly reduce（P<0.01）， Fe²⁺ level significantly reduced（P<0.01）， GSH level significantly increased（P<0.05， P<0.01）， and GPX4 protein expression significantly increased（P<0.05， P<0.01）. Among the group 1-3， the group 3 had the best detoxification effect. ConclutionProcessing with PRS juice can reduce the liver injury induced by DBR， and the mechanism may be related to the inhibition of ferroptosis in the liver.

Objective:To confirm the potential etiological factors of congenital aortic stenosis(AS)by genetic analysis on prenatal diagnostic results of the fetus with AS.Methods:Amniocentesis for chromosomal G-band karyotyping combinated with single nucleotide polymorphism array(SNP-array)analysis was conducted on the amniotic fluid collected from a 25-week pregnant woman diagnosed as"fetus AS";chromosome karyotyping was also performed on the peripheral blood of the fetal parents.Results:The fetal karyotype analysis showed a chimeric Y-chromosome isobaric double-adherent granules.The SNP-array analysis results revealed a 11.2 Mb duplication in the Yp11.31q11.21 region and a 14.8 Mb deletion in the Yq11.21q11.23 region.Both the parents presented a normal karyotype,suggesting it was a newfound mutation.After extensive genetic counseling,the pregnant woman and her family chose to terminate the pregnancy locally.Conclusion:The chromosomal karyotype of the chimeric Y-chromosome isobaric double-adherent granules may be a contributing factor to the AS phenotype in the male fetus.The combined use of chromosomal karyotyping and SNP-array analysis on the amniotic cells is instrumental in the early diagnosis of the disease.

Objective To analyze the clinical characteristics and regularity of aristolochic acid nephropathy (AAN) induced by drugs containing aristolochic acid. Methods The clinical data of 111 patients with AAN induced by aristolochic acid were reviewed. The clinical features, medication and treatment of AAN were analyzed. Results Among 111 patients, there were more females than males (2.58∶1), 101 cases (90.99%) were over 50 years old； the mean age was (63.70±11.67) years old;the average duration of medication was (8.08±6.94) years. The drugs involved were Guanxinsuhe pill and Longdanxiegan pill in 106 cases (95.50%). Serum creatinine increased in 108 cases, urea nitrogen increased in 106 cases and hemoglobin decreased in 103 cases, most of which were hypogravity urine, mild to moderate proteinuria and occult blood. Ultrasonic examination revealed that the kidneys were damaged to varying degrees. Pathological biopsy of kidney showed renal tubular damage. Most patients had an insidious onset and varying degrees of progression, which were not proportional to the age and the duration of taking the medicine. In clinical, the renal function was progressively damaged, most of which were irreversible and with a poor prognosis. Conclusion Patients with renal impairment differed greatly individually, and the renal damage was not paralleled with the medication duration and dose of drugs containing aristolochic acid.AAN progressed rapidly, and the disease still progressed even after stopping taking drugs containing aristolochic acid. Strengthening pharmacovigilance, implementing early diagnosis and effective intervention could help to reduce the occurrence of AAN and attenuate its development.

ObjectiveTo investigate the entrance surface dose （ESD） of digital radiography （DR）adult examinees in a grade A tertiary hospital in Shanghai， to analyze the dose level of the DR adult examinees， and to provide data for the development of DR typical dose reference. MethodsA DR equipment in the hospital was selected and the irradiation parameters and dose were determined in two randomly selected age groups （15‒39 years and 40‒69 years） of DR adult examinees. The examinations included chest PA， chest LAT， abdominal AP， pelvic AP， lumbar AP， lumbar LAT， thoracic AP， and thoracic LAT. The number of examinees in each exposure position was 20. ESD and effective dose were calculated for each age group and each position. ResultsA total of 320 examinees were investigated. The 75th percentiles of ESD in different exposure positions were as follows： chest PA 0.19 mGy；chest LAT 0.96 mGy；abdominal AP 3.63 mGy；pelvic AP 3.16 mGy；lumbar AP 9.27 mGy；lumbar LAT 18.29 mGy；thoracic AP 6.85 mGy；and thoracic LAT 13.40 mGy. ConclusionsThe differences between the estimated ESD and effective dose were large in different exposure positions、in the same exposure positions、and in the same positions with different exposure types， and there were statistically significant differences in ESD of examinees with different exposure positions. The estimated typical values of different exposure positions were apparently lower than the diagnostic reference level.

Objective:To compare Al 18F-1, 4, 7-trizacyclononane-1, 4, 7-triacetic acid (NOTA)-fibroblast activation protein inhibitor (FAPI)-04 PET/CT with 18F-FDG PET/CT in the evaluation of patients with initial gastric cancer. Methods:Twenty patients (13 males, 7 females, age: 27-77 years) with histologically proven gastric cancer were recruited prospectively between March 2021 and July 2022 in the First Affiliated Hospital of Zhengzhou University. Each patient underwent both 18F-FDG and Al 18F-NOTA-FAPI-04 PET/CT within one week. SUV max, tumor background ratio (TBR) and positive detection rate of the two methods were compared (Wilcoxon signed rank sum test, McNemar χ2 test). Results:Al 18F-NOTA-FAPI-04 showed higher SUV max and TBR than those of 18F-FDG in primary tumors (10.2(8.0, 13.7) vs 5.2(3.3, 7.7), z=-3.47, P=0.001; 7.6(5.6, 10.3) vs 2.4(1.8, 3.0), z=-3.85, P<0.001). For the detection of primary gastric cancer, the positive detection rate of Al 18F-NOTA-FAPI-04 PET/CT showed the trend of being higher than that of 18F-FDG PET/CT (95%(19/20) and 75%(15/20); χ2=2.25, P=0.125). For assessing lymph node metastasis, the detection rate of Al 18F-NOTA-FAPI-04 PET/CT was higher than that of 18F-FDG PET/CT (78.9%(101/128) vs 64.8%(83/128); χ2=13.47, P<0.001). The SUV max and TBR of Al 18F-NOTA-FAPI-04 in lymph node were higher than those of 18F-FDG (5.3(3.5, 9.2) vs 2.8(1.8, 4.7), z=-7.31, P<0.001; 4.6(2.6, 6.5) vs 1.7(1.0, 3.0), z=-8.44, P<0.001). For the detection of peritoneal carcinomatosis, Al 18F-NOTA-FAPI-04 PET/CT showed higher peritoneal cancer index (PCI), SUV max, and TBR compared to 18F-FDG PET/CT (PCI: 12.0(3.0, 29.8) vs 5.5(0.5, 17.5), z=-2.22, P=0.026; SUV max: 8.2(4.4, 12.5) vs 2.7(1.9, 4.0); z=-2.52, P=0.012; TBR: 5.1(2.9, 13.3) vs 1.1(0.9, 2.0); z=-2.52, P=0.012). Conclusion:Al 18F-NOTA-FAPI-04 PET/CT outperforms 18F-FDG PET/CT in primary and metastatic lesions of gastric cancer and might be a potential novel modality for imaging patients with gastric cancer.

The Wnt signaling pathway plays an important role in maintaining liver homeostasis and liver regeneration.In healthy livers,the Wnt signaling pathway is mostly inactive,but it is continuously overactivated during cell renewal or regeneration processes,as well as in certain pathological conditions,diseases,precancerous states,and cancers.Persistent liver cell injury often leads to chronic liver diseases such as liver fibrosis,liver cirrhosis,and liver cancer.This article summarizes the basic structural features of the Wnt signaling pathway and analyzes its important role in the pathological progression of various liver diseases,so as to provide new ideas for the prevention and treatment of liver diseases in clinical practice.

Objective This article aims to investigate the association between hypertension and the risk of GSD by conducting a national multicenter study,a systematic review,and a meta-analysis.Methods The study was conducted in three stages.In the first stage,subjects were recruited for health examination in four hospitals in Chengdu,Tianjin,Beijing,and Chongqing,China,from 2015 to 2020,and the multivariate logistic regression analysis was used to investigate the association between hypertension and the risk of GSD in each center.In the second stage,Embase,PubMed,Wanfang Data,VIP,and CNKI databases were searched for related studies published up to May 2021,and a meta-analysis was conducted to further verify such association.In the third stage,the random effects model was used for pooled analysis of the results of the multicenter cross-sectional study and the findings of previous literature.Results A total of 633 948 participants were enrolled in the cross-sectional study,and the prevalence rate of GSD was 7.844%.The multivariate logistic regression analysis showed that hypertension was positively associated with the risk of GSD(P＜0.05).Subgroup analysis showed that there was no significant difference in the association between hypertension and GSD between individuals with different sexes,ages,and subtypes of GSD.A total of 80 articles were included in the systematic review and the meta-analysis,and the results showed that the risk of GSD was increased by 1.022 times for every 10 mmHg increase in diastolic pressure and 1.014 times for every 10 mmHg increase in systolic pressure.Conclusion Hypertension significantly increases the risk of GSD,and the findings of this study will provide a basis for the etiology of GSD and the identification of high-risk groups.
