OBJECTIVE To investigate the effects of alirocumab combined with atorvastatin on clinical efficacy and safety of patients with acute coronary syndrome （ACS） who underwent percutaneous coronary intervention （PCI）. METHODS A total of 207 patients with ACS who underwent PCI in our hospital from January 2021 to December 2023 were randomly divided into alirocumab group， ezetimibe group and control group， with 69 cases in each group. All patients received routine thrombosis prevention and antihypertensive treatment after PCI. On this basis， patients in the control group were treated with atorvastatin （20 mg/time， once a day）； patients in the ezetimibe group were treated with ezetimibe （10 mg/time， once a day） + atorvastatin （20 mg/time， once a day）； patients in the alirocumab group were treated with alirocumab （75 mg/time， once every 2 weeks） + atorvastatin （20 mg/time， once a day）. All patients in the three groups were treated for 8 weeks and followed up for another 6 months after treatment. The levels of cardiac function and lipid metabolism indices before and after treatment， as well as the occurrence of major adverse cardiovascular event （MACE） and other adverse drug reaction （ADR） during the follow-up period were compared among the three groups. RESULTS After treatment for 8 weeks， the levels of cardiac function and lipid metabolism indices in the three groups were significantly improved compared with those before treatment （P＜0.05）. Compared with the control group and ezetimibe group， the left ventricular ejection fraction in the alirocumab group was significantly increased， and the left ventricular end-diastolic diameter （LVEDD） was significantly shortened （P＜0.05）. Compared with control group， LVEDD of ezetimibe group was significantly shortened （P＜0.05）， the levels of total cholesterol， triglyceride and low-density lipoprotein cholesterol in the alirocumab group and ezetimibe group were significantly decreased （P＜0.05）. During the follow-up period， there was no significant difference in the total incidence of MACE and the total incidence of other ADR such as headache and abdominal pain among the three groups （P＞0.05）. CONCLUSIONS Alirocumab combined with atorvastatin can significantly improve cardiac function and regulate lipid metabolism indices in patients with ACS after PCI without increasing the risk of MACE or other ADR.

ObjectiveTo observe and analyze the plasma metabolite differences among colorectal cancer patients with spleen-qi deficiency， damp-heat stasis-toxin syndrome（SRYD）， non-spleen-qi deficiency， damp-heat stasis-toxin syndrome（non-SRYD）， and normal human beings（Normal）， aiming to identify unique metabolites specific to SRYD colorectal cancer patients and their potential biomarkers. MethodsBased on the diagnostic criteria of SRYD and non-SRYD colorectal cancer， 30 patients were included， including 10 patients with SRYD colorectal cancer and 20 patients with non-SRYD colorectal cancer， while 10 individuals were recruited for the Normal group. Metabolome sequencing of plasma from the three groups was performed by ultra-performance liquid chromatography-quadrupole-electrostatic field orbitrap mass spectrometry（UPLC-Q-Exactive-Orbitrap-MS）. Multivariate statistical analysis were performed by principal component analysis（PCA） and partial least squares-discriminant analysis（PLS-DA）， and the intergroup differential metabolites were identified based on variable importance in the projection（VIP） value>1 and t-test P<0.05. And pathway enrichment analysis based on Kyoto Encyclopedia of Genes and Genomes（KEGG） was performed to explore the metabolites and metabolic pathways specific to SRYD colorectal cancer patients. ResultsMetabolome sequencing results showed some differences in metabolic profiles between the groups. A total of 111 plasma differential metabolites were found in the SRYD group and the Normal group， of which 31 were up-regulated and 80 were down-regulated， mainly including stearoyl lysophosphatidylcholine， indole-3-acrylic acid， and dehydroepiandrosterone sulfate（P<0.05）. The non-SRYD group exhibited 97 differentially expressed metabolites compared to the Normal group， with 36 up-regulated and 61 down-regulated， mainly including stearoyl lysophosphatidylcholine， sphingosine， and palmitoyl lysophosphatidylcholine（P<0.05）. And the SRYD group exhibited 19 differentially expressed metabolites compared to the non-SRYD group， of which 5 were up-regulated and 14 were down-regulated， mainly including dihydrosphingosine， palmitic acid， and linoleoylethanolamide（P<0.05）. The significant differential metabolites were subjected to KEGG analysis to obtain significantly enriched metabolic pathways in each group， and the results showed that 11 metabolic pathways such as primary bile acid synthesis， cholesterol metabolism and bile secretion were differential signaling pathways specific to SRYD colorectal cancer. Further retrieval of the above key signaling pathways showed that bile acids were up-regulated in both bile secretion and primary bile acid synthesis pathways， and there was a trend of up-regulation of glycochenodeoxycholic acid， taurochenodeoxycholic acid， and chenodeoxycholic acid. ConclusionPrimary bile acid synthesis， cholesterol metabolism， and bile secretion-related pathways may be differential signaling pathways specific to SRYD colorectal cancer， and bile acid is a core molecule in the metabolic pathway， which can serve as potential biomarkers closely related to the development and progression of SRYD colorectal cancer.

Qingfeitang， specialized in resolving phlegm to stop cough and producing fluid to moisten dryness， is a classic prescription inherited and developed by physicians of successive generations and has been included in the Catalogue of Ancient Classic Prescriptions （First Batch） published by the National Administration of Traditional Chinese Medicine （TCM） in 2018. Relevant ancient books data and modern literature were collected by bibliometrics to analyze the historic origin， formula composition， herb origin， preparation methods， processing methods， clinical effect， and indications of Qingfeitang. The key information of Qingfeitang was summarized to provide reference for the clinical application of the decoction. In this study， a total of 43 pieces of effective data on relevant ancient literature， including 35 ancient TCM books， were collected based on a systematic collation of relevant historic and modern literature. Results showed that "Qingfeitang" was originated from the "Renshen Qingfeitang" recorded in the Taiping Holy Prescriptions for Universal Relief from the Qing dynasty. The name of "Qinfeitang" was first recorded in the Yeshi Luyanfang written by YE Dalian in the Song dynasty. We suggested the modern dosage and usage of Qingfeitang as follows： "Scutellariae Radix of 5.60 g， Platycodon grandiflora， Poria， Tangerine， Fritillaria， and Cortex Mori of 3.73 g respectively， Angelicae Sinensis Radix， Asparagi Radix， Gardeniae Fructus， Armeniacae Semen Amarum， and Ophiopogonis Radix of 2.61 g respectively， Schisandra of 1 g， and Glycyrrhizae Radix et Rhizoma of 1.12 g， and they were taken 3 times daily. The above formula is recommended to be decocted with 400 mL of water， with 3.37 g ginger and 6 g jujubae fructus， to 320 mL， and taken after a meal， three times per day". Qingfeitang has the effect of resolving phlegm to stop cough and producing fluid to moisten dryness， specialized in treating cough， asthma， rash， and other symptoms in ancient times. Modern applications are mainly focused on the respiratory system， used for treating diseases such as bronchopneumonia and cough. The above research results provide a reference basis for the later development and research of Qingfeitang.

Objective: To analyze the correlation between the levels of vitamin A, vitamin D, vitamin E with body fat mass percentage(FMP) as well as lifestyle factors among primary school students, so as to provide references for exploring the vitamin nutritional status of primary school students and its potential influencing factors. Methods: From September 1 to October 30, 2021, a cluster sampling method was used to select 750 thirdgrade students from eight primary schools in Luohu District, Shenzhen. Their body composition was measured, and blood samples were collected to detect the serum levels of vitamin A, vitamin D, and vitamin E using a mass spectrometer. Dietary and exercise habits were collected through questionnaires. Mann-Whitney U test and Kruskal-Wallis H rank sum test were used for inter group comparisons, spearman correlation was used for correlation analysis,and Logistic regression model was used to analyze the association between lifestyle and vitamin content. Results: The overall level of vitamin A in school aged children was 0.4 (0.4, 0.5) mg/L, with a deficiency rate of 0 and a marginal deficiency rate of 5.1%; the level of vitamin D was 26.0 (22.0, 30.0) ng/mL, with a deficiency rate of 0.4% and an insufficiency rate of 12.7%; the content of vitamin E was 11.8 (10.1, 13.5) mg/L, with an insufficiency rate of 0.8%. Spearman correlation analysis showed that vitamin A was positively correlated with FMP in the total population, boys, girls, and normal weight population ( r =0.18, 0.18, 0.20, 0.10), and vitamin D was positively correlated with FMP in the total population and obese population ( r =0.08,0.16)(all P <0.05). Logistic regression analysis showed that marginal deficiency of vitamin A was associated with consumption of animal, snack, and dairy/egg/bean foods ( OR =0.45, 0.55, 0.59); whether vitamin D was deficient was influenced by gender ( OR =2.65) and exercise ( OR = 1.96 ) (all P <0.05). Conclusion Vitamin A, vitamin D and vitamin E levels are associated with body fat percentage, with significant variations in vitamin status among individuals of different body types, necessitating targeted supplementation.

This paper summarized the experience in treating flat warts by Professor XU Xian based on the theory of Bai Qi （白气） micro-discharge. Flat warts is considered as a minor skin disease. Wind-damp attacking the exterior and contention between the muscles are the prerequisites for its occurrence， and failure to diffuse due to wei （卫） constraint， and qi discharge to striae and interstices are the core pathogenesis. For treatment， the core principle is to treat minor diseases with minor adjustment， and therefore， the method of dispelling wind and overcoming dampness is used to produce slight sweating and relieve the symptoms， and by taking advantage of the situation， the constraint is unblocked with diffusion and dispersion. Simultaneously， it is paid attention to not over-damaging blood vessels during treatment to avoid causing other symptoms. Self-made Modified Maxing Yigan Decoction （麻杏薏甘汤） is recommended as the basic formula for flat warts， together with self-made Xi You Formula （洗疣方） in external administration to restore defense qi， eliminate pathogenic qi and remove the warts.

AIM: To understand the current status and differences in visual acuity of children of the same age from different regions of Xi'an, and to take an effective basis for the prevention of children's myopia.METHODS: Random stratified sampling was used to select the uncorrected distance visual acuity and computed dioptric data of 41 285 children aged 6-12 from 6 towns, 10 urban and rural areas and 112 country schools screened by Xi'an Central Hospital in December 2022.RESULTS: The myopia detection rate in different regions of Xi'an is 47.16% in towns, 38.59% in urban and rural areas, and 32.29% in the country, and the total myopia rate is 37.50%. The myopia rate of 6-12 years old in towns is higher than that in urban and rural areas, and that of urban and rural areas is higher than that of country; the myopia rate of girls is higher than that of boys; myopia rate increases with age; mild myopia: the myopia rate in towns is significantly higher than that of the urban and rural areas and the country; high myopia: the myopia rate in the country is significantly higher than that of the towns and the urban and rural areas. The total rate of deficient hyperopia reserves in different regions of Xi'an is 92.08% in towns, 93.67% in urban and rural areas, and 90.92% in the country, and the total rate of deficient hyperopia reserves is 92.09%. The rate of deficient hyperopia reserves at the age of 6-12 is higher in the urban and rural areas than in the towns, and higher in the towns than in the country; the total rate of deficient hyperopia reserve is higher in girls than in boys; it is the peak period of the development of hyperopia reserve rate before the age of 8.CONCLUSION: The total myopia rate and the total vision reserve deficiency rate of 6-12 years old in different regions of Xi'an are different, and 8-9 years old is the accelerated period of myopia development, and the peak of deficient hyperopia reserve is before the age of 8 years old. With the growth of age, the myopia rate shows a certain growth trend, and the rate of deficient hyperopia reserve shows a decreasing trend after reaching the peak. The total myopia rate and insufficient acuity reserve rate of girls are higher than those of boys.

Objective To investigate the predictive value of artificial intelligence(AI)-assisted high-resolution computed tomo-graphy(HRCT)in degree of invasion of early lung adenocarcinoma with subsolid nodules(SSN).Methods Ninety patients(a total of 90 SSN)with pulmonary SSN on AI-assisted HRCT scans were selected as the study subjects.According to the degree of invasion in pathology,the cases were divided into invasive adenocarcinoma(IAC)group(48 cases)and non-invasive adenocarcinoma(non-IAC)group(42 cases).The differences in general information,pulmonary SSN morphological characteristics,and related parameters were compared between the two groups.The influencing factors were analyzed using a multiple logistic regression model,and a nomo-gram prediction model was constructed.The diagnostic efficacy of the model was evaluated using receiver operating characteristic(ROC)curves,calibration curves,and clinical decision curves.Results Between the two groups,there were statistically significant differences in age,nodular nature,shape,tumor-lung interface,vacuole sign,burr sign,air-bronchial sign,vascular bunching sign and pleural indentation sign.Compared with the non-IAC group,the CT maximum value,energy,variance of CT value,CT average value,maximum surface area,mean long and short diameter,3D long diameter,surface area,volume,mass and entropy of the IAC group significantly increased,while the CT minimum value,compactness and sphericity of the IAC group significantly decreased.The results of multiple logistic regression model showed that burr sign,vascular bunching sign,tumor-lung interface,mass,pleural indentation sign,and CT average value were independent risk factors affecting the development of SSN into early IAC.Finally,a nomogram pre-diction model was constructed based on risk factors,and the results of ROC curves,calibration curves and clinical decision curves showed that the predictive model had good diagnostic efficacy.Conclusion HRCT imaging features assisted by AI have a high pre-dictive value for the degree of invasion in early lung adenocarcinoma with SSN,and focusing on the burr sign,vascular bunching sign,tumor-lung interface,mass,pleural indentation sign,and CT average value can improve clinical treatment and prognosis for patients.
