Hepatocellular carcinoma (HCC) is a leading cause of cancer-associated death globally. Liver transplantation (LT) has emerged as a key treatment for patients with HCC, and the Milan criteria have been adopted as the cornerstone of the selection policy. To allow more patients to benefit from LT, a number of expanded criteria have been proposed, many of which use radiologic morphological characteristics with larger and more tumors as surrogates to predict outcomes. Other groups developed indices incorporating biological variables and dynamic markers of response to locoregional treatment. These expanded selection criteria achieved satisfactory results with limited liver supplies. In addition, a number of prognostic models have been developed using clinicopathological characteristics, imaging radiomics features, genetic data, and advanced techniques such as artificial intelligence. These models could improve prognostic estimation, establish surveillance strategies, and bolster long-term outcomes in patients with HCC. In this study, we reviewed the latest findings and achievements regarding the selection criteria and post-transplant prognostic models for LT in patients with HCC.

Objective:To analyze the short-term clinical efficacy and safety of arsenic trioxide (ATO) combined with a modified N7 induction regimen in the treatment of children with high-risk neuroblastoma (NB).Methods:This study was a prospective, single-arm, multicenter phase Ⅱ clinical study. Sixty-seven high-risk NB children from eight units of Sun Yat-sen Memorial Hospital of Sun Yat-sen University, Wuhan Children′s Hospital of Tongji Medical College of Huazhong University of Science and Technology, First Affiliated Hospital of Guangxi Medical University, Hainan General Hospital, Affiliated Hospital of Guangdong Medical University, Kunming Children′s Hospital, Tongji Hospital of Tongji Medical College of Huazhong University of Science and Technology, and Guangdong Provincial Agricultural Reclamation Center Hospital were enrolled from January 2019 to August 2023 and were treated with ATO combined with a modified N7 induction regimen. The efficacy and adverse effects at the end of induction chemotherapy were assessed and analyzed, and the differences in the clinical characteristics were further compared between the treatment-responsive and treatment-unresponsive groups by using the Fisher′s exact test.Results:Among 67 high-risk NB children, there were 40 males (60%) and 27 females (40%), with the age of disease onset of 3.5 (2.6, 4.8) years. Primary NB sites were mostly in retroperitoneum (including adrenal gland) (56/67, 84%) and the common metastases sites at initial diagnosis were distant lymph node in 25 cases (37%),bone in 48 cases (72%),bone marrow in 56 cases (84%) and intracalvarium in 3 cases (4%). MYCN gene amplification were detected in 28 cases (42%). At the end of induction, 33 cases (49%) achieved complete remission, 29 cases (43%) achieved partial remission, 1 case (1%) with stable disease, and 4 cases (6%) were assessed as progressive disease (PD). The objective remission rate was 93% (62/67) and the disease control rate was 94% (63/67). The percentage of central system metastases at the initial diagnosis was higher in the treatment-unresponsive group than in the treatment-responsive group (2/5 vs. 2% (1/62), P=0.013), whereas the difference in MYCN gene amplification was not statistically significant between two groups (3/5 vs.40% (25/62), P=0.786). Grade Ⅲ or higher adverse reactions during the induction chemotherapy period were myelosuppression occurred in 60 cases (90%), gastrointestinal symptoms occurred in 33 cases (49%), infections occurred in 20 cases (30%), hepatotoxicity occurred in 4 cases (6%), and cardiovascular toxicity occurred in 1 case (2%). There were no chemotherapy-related deaths. Conclusion:ATO combined with N7-modified induction regimen had a superiority in efficacy and safety, which deserved further promotion in clinical practice.

Objective To explore the birthdate circuit qi endowment of the five circuit phases and six climatic factors in the female patients with benign and malignant breast tumors,and to analyze the benign and malignant tendency of breast tumors.Methods The birth date information of 723 patients with breast malignant tumor(breast cancer)and 1 595 patients with benign breast tumor were collected from the electronic medical record system of the First Affiliated Hospital of Guangzhou University of Chinese Medicine.SPSS 25.0 statistical software was used to analyze the circuit qi information of the two groups of patients.Results(1)The analysis of suiyun(yearly evolutive phase)showed that the patients born in the years of excessive wood phase,excessive fire phase,and deficiency earth phase tended to suffer from breast cancer,while the patients born in the years of deficiency gold phase,deficiency wood phase,and excessive water phase tended to suffer from benign breast tumors.(2)The analysis of dominant qi(regular yearly circuit qi)showed that the patients born at the time of shaoyin monarch fire were more likely to suffer from breast cancer,while patients born at the time of jueyin wind-wood and taiyin damp-earth were more likely to suffer from benign breast tumors.(3)The analysis of guest qi(alterable yearly circuit qi)showed that the patients born at the time of jueyin wind-wood and yangming dry-gold were more likely to suffer from breast cancer,and the patients born at the time of shaoyang ministerial fire and taiyang cold-water were more likely to suffer from benign breast tumors.(4)The analysis of birth season showed that the patients born in spring were more likely to suffer from breast cancer.(5)The analysis of the combination of circuit and qi(circuit phases and climatic factors)showed that the patients born in the year of xiaoni(circuit phases generating climatic factors),buhe(circuit phases restricting climatic factors),and tianxing(sitian climatic factors restricting the predominant circuit phases)tended to suffer from breast cancer,and patients born in the year of suihui(yearly heavenly-stem circuit phase accorded with the yearly earthly-branch circuit qi)and tongsuihui(deficiency yearly circuit phase in accordance with the second half of the alterable yearly circuit qi)tended to suffer from benign breast tumors.(6)The analysis of celestial control-terrestrial effect showed that the combination of celestial control-terrestrial had no significant effect on the incidence of breast cancer or benign breast tumors(P＞0.05).Conclusion(1)Certain differences and tendencies of birthdate circuit qi endowment exist between benign breast tumors and breast cancer.(2)The birthdate circuit qi endowment of breast cancer is characterized by wind and heat,and mainly involves liver,spleen,heart and kidney.Compared with patients with benign breast tumors,patients with breast cancer usually have the excess and heat biased constitution endowment.

Objective:To analyze the expression of B-cell development-related genes in acute B lymphoblastic leukemia (B-ALL),and to explore the relationship between B-cell development-related genes and the prognosis of B-ALL patients.Methods:The GEO and TARGET databases were integrated to analyze the differential expression of B-cell development-related genes between the healthy persons and B-ALL patients and their differential expression in the B-ALL relapse and non-relapse groups.Cox single factor regression and Lasso regression were used to constructe a B-ALL specific prognosis model of B-cell development-related genes.The prognostic value of this model was analyzed by Cox multiple factor regression.The risk scores of different subtypes of B-ALL was analyzed.In the real world,the correlation between the prognostic model of B-cell development-related genes and clinical outcomes was verified through the transcriptome sequencing results of B-ALL patients.In addition,the correlation between this prognostic model and other B-ALL prognostic models was also analyzed.At last,Metascape was used to evaluate the pathway and function enrichment status related to the prognosis model.Results:There were 1097 genes specifically expressed in B-ALL and related to B cell development,27 of which were up-regulated in the B-ALL relapse group,and 37 genes were down-regulated in the B-ALL relapse group.14 genes were further selected to be included in the B-cell development-related prognosis model (CDC25B,CKAP4,DSTN,IGF2R,NDUFA4,ODC1,PAX5,SH3BP4,SLC27A5,APAF1,ARRB2,HHEX,IL13RA1,UVRAG)based on Cox single factor regression and Lasso regression.Risk scoring of patients with B-ALL based on the 14 genes prognosis model,the prognosis of 134 patients in the low-risk scoring group (score>0.11) was better than those in the patients with high-risk scores (score≤0.11 ).Multivariate analysis showed that the risk score of B-cell development-related genes was an independent prognostic factor.And the proportion of hyperdiploid positive children in the low-risk scoring group was significantly higher than that in the high-risk scoring group,while the proportion of TCF3/PBX1 positive children in the high-risk scoring group was significantly higher than that in the low-risk scoring group.At the same time,the real-world data showed that the prognosis of patients with B-ALL in the high-risk scoring group was worse than those of the patients with low-risk scores in Xi'an Children's Hospital.And the risk score of B-cell development-related genes in patients with B-ALL death was higher than that in patients with B-ALL non-death.In addition,there is a positive correlation between the risk score calculated by the metabolic-related gene prognostic scoring system and the risk score calculated by the B-cell developmental-related gene prognostic model.At last,differential gene enrichment analysis suggested that the prognosis risk was related to the process of embryonic development and differentiation to various systems,especially to the B cell receptor signaling pathway.Conclusion:The specific expression of B-cell development-related genes in B-ALL is related to the prognosis of B-ALL.The prognosis model composed of 14 genes is expected to be a new prognostic marker for children with B-ALL.

Objective:To compare the efficacy and safety of red light and daylight photodynamic therapy in the treatment of facial common acne.Methods:From March 2019 to November 2019, 52 patients with facial common acne who received 5-aminolevulinic acid photodynamic therapy in the Department of Dermatology, Chongqing Hospital of Traditional Chinese Medicine were enrolled, including 34 males and 18 females, aged 18-35 years, with an average age of 23.2 years. A 5% concentration of 5-aminolevulinic acid was applied to the entire face, with the right side of the face being exposed to red light for 20 minutes and the left side to daylight for 2 hours. The treatment was administered once a week for a total of 4 sessions. After the treatment, the acne remission, adverse reactions, and patient satisfaction on both sides of the face were compared.Results:Compared with before treatment, the number of inflammatory and non-inflammatory lesions on both sides of the face in the enrolled patients decreased, and there was no significant difference in the clearance rate of skin lesions between the two sides [53.7% (28/52) vs 59.1% (31/52), χ 2=0.89, P>0.05]. The overall effective rate on the red light side was 88.5% (46/52), and 82.7% (43/52) on the daylight side, with no significant difference between the two (χ 2=0.38, P>0.05). In terms of adverse reactions, mild erythema was common, and it was less on the daylight side than on the red light side [34.6% (18/52) vs 19.2% (10/52), χ 2=5.98, P<0.05]. During the treatment period, the pain score on the daylight side decreased compared to the red light side [(7.6±2.3) vs (4.1±1.3), t=13.10, P<0.001]. Overall satisfaction with the daylight side was reported in 49 cases (94.2%), and with the red light side in 37 cases (71.2%), with the daylight side being higher than the red light side, and the difference was statistically significant (χ 2=9.60, P<0.05). Conclusion:Daylight photodynamic therapy is as effective as red light photodynamic therapy for common acne, but it produces fewer adverse reactions and higher patient satisfaction.

To study the residue and dietary risk of propiconazole in Panax notoginseng and the effects on physiological and bioche-mical properties of P. notoginseng, we conducted foliar spraying of propiconazole on P. notoginseng in pot experiments. The physiolo-gical and biochemical properties studied included leaf damage, osmoregulatory substance content, antioxidant enzyme system, non-enzymatic system, and saponin content in the main root. The results showed that at the same application concentration, the residual amount of propiconazole in each part of P. notoginseng increased with the increase in the times of application and decreased with the extension of harvest interval. After one-time application of propiconazole according to the recommended dose(132 g·hm~(-2)) for P. ginseng, the half-life was 11.37-13.67 days. After 1-2 times of application in P. notoginseng, propiconazole had a low risk of dietary intake and safety threat to the population. The propiconazole treatment at the recommended concentration and above significantly increased the malondialdehyde(MDA) content, relative conductivity, and osmoregulatory substances and caused the accumulation of reactive oxygen species in P. notoginseng leaves. The propiconazole treatment at half(66 g·hm~(-2)) of the recommended dose for P. ginseng significantly increased the activities of superoxide dismutase(SOD), peroxidase(POD), and catalase(CAT) in P. notoginseng leaves. The propiconazole treatment at 132 g·hm~(-2) above inhibited the activities of glutathione reductase(GR) and glutathione S-transferase(GST), thereby reducing glutathione(GSH) content. Proconazole treatment changed the proportion of 5 main saponins in the main root of P. notoginseng. The treatment with 66 g·hm~(-2) propiconazole promoted the accumulation of saponins, while that with 132 g·hm~(-2) and above propiconazole significantly inhibited the accumulation of saponins. In summary, using propiconazole at 132 g·hm~(-2) to prevent and treat P. notoginseng diseases will cause stress on P. notoginseng, while propiconazole treatment at 66 g·hm~(-2) will not cause stress on P. notoginseng but promote the accumulation of saponins. The effect of propiconazole on P. notoginseng diseases remains to be studied.
