Angiogenesis is a key process in the development and progression of hepatocellular carcinoma （HCC） and can provide essential material conditions for the proliferation, invasion, and metastasis of HCC cells. Inhibition of angiogenesis has become a research hotspot in the field of HCC therapy. Traditional Chinese medicine has become a potential drug for HCC therapy due to its characteristics of multiple targets and pathways, enhancing efficacy and reducing toxicity, improving tumor prognosis, and prolonging survival time. Modern studies have confirmed that traditional Chinese medicine can inhibit tumor angiogenesis by inhibiting the expression of angiogenic factors, upregulating the levels of anti-angiogenic factors, inhibiting endothelial cell proliferation, reducing the microvascular density of HCC tissue, and regulating related signaling pathways, and therefore, traditional Chinese medicine has unique advantages in the treatment of HCC. By summarizing related articles in China and globally in recent years, this article analyzes the mechanism of action of traditional Chinese medicine on inhibiting HCC angiogenesis, in order to provide certain theoretical basis and reference for the optimization of HCC treatment strategies in clinical practice.

Based on the ambient air quality monitoring data of Xi′an from September to November in 2021,the pollution characteristics of regional PM2. 5 in Xi′an before, during and after the 14th National Games of the People′s Republic of China ＆ the National Games for Persons with Disabilities were analysed. In addition, the air mass transport pathways, potential source areas and their contributions to PM2. 5 mass concentrations were also determined by the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model, potential source contributing factor (PSCF) method and weighted concentration trajectory (CWT) method. The results showed that during the observation, Southeasterly winds dominated in Xi′an, and the PM2. 5 concentration was lowest during the 14th National Games of the People′s Republic of China (NG) and highest after the end of the National Games for Persons with Disabilities (PG）. The air mass transport pathways of PM2. 5 were dominated by the local transport near Southern Shaanxi, the proximity transport in the Easterly and Southerly directions, and the long-range transport in the Northwesterly direction. Potential source regions of PM2. 5 were mainly located in the cities and areas of Henan, Hubei, Guizhou, Sichuan, Chongqing, Xinjiang Uygur Autonomous Regions, Inner Mongolia Autonomous Region, Southern Shaanxi, and the junction of cities in Southern Shaanxi and neighboring provinces.

Objective To compare the diagnostic performance of gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB) enhanced magnetic resonance imaging (MRI)and multi-detector computed tomography (MDCT) in detecting liver metastases from metastatic colorectal cancer (mCRC). Methods We made a retrospective collection of 128 patients diagnosed with mCRC from May 2019 to June 2022 at Haikou Hospital, Xiangya School of Medicine, Central South University and Xijing Hospital, Air Force Military Medical University. All patients underwent Gd-EOB MRI and MDCT imaging. Three radiologists judged the accuracy, sensitivity, specificity, positive predictive value and negative predictive value of the two modalities for colorectal liver metastases, respectively. Results Of the 128 patients diagnosed with mCRC, a total of 462 lesions were obtained, with 424 positive and 38 negative metastases confirmed by pathology. In the interpretation of physician A, Gd-EOB MRI judged 404 positive and 38 negative liver metastases, with accuracy of 95.67%, sensitivity of 95.28%, specificity of 100.00%, a positive predictive value of 100%, and a negative predictive value of 65.52%. MDCT judged 337 positive and 37 negative liver metastases, with accuracy of 80.95%, sensitivity of 79.48% and specificity of 97.37%, a positive predictive value of 99.70%, and a negative predictive value of 29.84%. In the interpretation of physician B, Gd-EOB MRI judged 403 positive and 36 negative liver metastases, with accuracy of 95.02%, sensitivity of 95.05%, specificity of 94.74%, a positive predictive value of 99.51%, and a negative predictive value of 64.91%. MDCT judged 335 positive and 35 negative liver metastases, with accuracy of 80.09%, sensitivity of 79.01%, specificity of 92.11%, a positive predictive value of 99.11%, and a negative predictive value of 28.23%. In the interpretation of physician C, Gd-EOB MRI judged 406 positive and 38 negative liver metastases, with accuracy of 96.10%, sensitivity of 95.75%, specificity of 100.00%, a positive predictive value of 100.00%, and a negative predictive value of 67.86%. MDCT judged 352 positive and 34 negative liver metastases, with accuracy of 83.55%, sensitivity of 83.02%, specificity of 89.47%, a positive predictive value of 98.88%, and a negative predictive value of 32.08%. Gd-EOB MRI judged the nature of liver metastases with higher accuracy, sensitivity and negative predictive value than MDCT, and had better agreement with pathological examination results in the judgment of physician A and physician C (Kappa=0.770, 0.788). In physician B's judgment, the agreement with pathological findings was fair (Kappa=0.731), while the agreement between the results of MDCT examination and pathological findings was poor (Kappa=0.379, 0.378 and 0.400). Conclusion Gd-EOB MRI has higher accuracy, sensitivity and positive predictive rate than MDCT in diagnosing colorectal liver metastasis, and has higher diagnostic performance. Therefore, it can provide more valuable reference information for clinical differential diagnosis. Subcapsular lesions, peribiliary metastases and hepatic steatosis can reduce the diagnostic performance of MDCT, while Gd-EOB MRI detection can provide more accurate results than MDCT.

Objective To analyzes the morbidity, mortality and DALYs changes of upper respiratory tract infection in China from 1990 to 2019, and to provides data support for the formulation of relevant prevention and control strategies. Methods Joinpoint regression was used to analyze the trend changes of morbidity, mortality and DALYs in China from 1990 to 2019, the age-period-cohort model was used to estimate the age, period and cohort RR values of morbidity and mortality of upper respiratory tract infection. Results The incidence of upper respiratory tract infections in 2019 was higher than in 1990, but the incidence and standardized incidence were slightly lower than in 1990. The number of deaths, mortality, standardized mortality, DALYs, DALYs, and standardized DALY rates for upper respiratory tract infections in 2019 were lower than in 1990.From 1990 to 2019, the standardized mortality rate and standardized DALY rate showed a downward trend year by year, with an average annual decrease of 8.2% (95%CI: -8.7%--7.8%) and 2.4% (95%CI: -2.5%--2.2%), and the decline trend in women was more obvious than that in men. The results of the age-period-cohort model showed that the age-effect RR value of the incidence of upper respiratory tract infection in Chinese men from 1990 to 2019 showed a downward trend year by year, the age-effect RR value of female incidence showed an increasing trend, and the age-effect RR value of mortality showed a downward trend with the increase of age. The period effect of morbidity was at higher risk in women than in men, and the period RR of mortality decreases gradually over time. The birth cohort RR value for morbidity showed a downward trend in men, and conversely in women, the birth cohort RR value for mortality showed a decreasing trend year by year. Conclusion According to the relevant characteristics of the disease burden of upper respiratory tract infection in China, targeted measures are formulated to prevent the onset of upper respiratory tract infection.

Rhabdomyosarcoma (RMS) is the most common soft tissue tumor of childhood; about 80% of cases occur before the age of 21 with the remaining 20% evenly spread throughout the remaining decades. A primary paratesticular site is considered to have a good prognosis in comparison with other RMS sites. Histologically, any subtype of RMS, including alveolar, pleomorphic, embryonal, and mixed type, may occur in the paratesticular region, but only a relatively small number of cases are mixed and this variant has a poor prognosis. We report a case of paratesticular RMS (mixed embryonal and alveolar type) in a 16-year-old boy. more...

ζ-Carotene desaturase（ZDS）is one of the key enzymes regulating carotenoids biosynthesis. Here having the high-generation inbred broccoli（Brassica oleracea var. italica）line‘ZN09’as testing materials and BoZDS as target gene, then two target sites on the first exon of BoZDS were selected to construct CRISPR/Cas9 vector for stable genetic transformation. For the target site 1, the transformation efficiency and the mutation rate were 0.80% and 15.79%, respectively, and three heterozygous mutants were generated. For the target site 2, the transformation efficiency was 0.84%, and the mutation rate was 36.84%, and seven mutants were generated, including two homozygous, two heterozygous, and three chimeric mutants. All of the mutant plants showed albino or mottled phenotype. The L* and a* values of mutant plants were significantly higher than those of wild-type plants, while the b* value decreased. To sum up, a stable genetic system for CRISPR/Cas9- mediated gene editing in broccoli was established, and BoZDS was effectively edited. Our results provide the technical support for gene function study and germplasm innovation of broccoli by using gene editing technology. [ABSTRACT FROM AUTHOR] more...

In order to confirm the target traits and genetic stability of transgenic maize 2HVB5,Southern blot, ELISA, bioassay in laboratory and field, target herbicide-tolerance analysis and agronomic traits investigation were carried out on BC5S1 and BC5S2 transgenic maize 2HVB5 plants which had been backcrossed to Zheng 58. The results showed that the target genes cry2Ah-vp and bar were integrated into maize genome in the form of single copy and steady inheritance in 2HVB5 plants. Cry2Ah-VP and PAT proteins were expressed in different stages and different tissues in 2HVB5 plants, and the expressions in the leaves were relatively high, reaching 2-3.5 μg/g fresh weight (FW) and 8-17 μg/g FW respectively. The bioassay results in laboratory showed that 2HVB5 plants had high resistance to armyworm (Mythimna separate) and cotton bollworm (Helicoverpa armigera), the corrected mortality rates of armyworm and cotton bollworm larvae reached 100% on 4-5 d,and the 2HVB5 plants presented a significant weight inhibiton to fall armyworm (Spodoptera frugiperda). The bioassay results in field also showed that 2HVB5 plants had high resistances to armyworm and cotton bollworm, the average resistance indexes were 1.19-1.29 and 0.60-0.73, respectively. The transgenic maize 2HVB5 tolerated 4 times the recommended medium dose for glufosinate application in field, and there were no significant differences in agronomic traits compared with the control Zheng 58. These indicate that transgenic maize 2HVB5 is of genetic stability and high insect resistance and herbicide resistance. It can be used for the control of corn pests, especially Noctuidae pests, and has a prospect of commercial application. [ABSTRACT FROM AUTHOR] more...
