【Objective】 To summarize the clinicopathological features and prognosis of young patients (18-40 years old) with non-clear cell renal cell carcinoma (nccRCC) treated in a single center to provide reference for the diagnosis and treatment of similar patients. 【Methods】 Clinical data of 113 nccRCC patients treated during Jan. 2012 and Aug. 2022 were retrospectively analyzed, including 57 males (50.4%) and 56 females (49.6%). The average age of onset was (31.6±5.8) years. Among all patients, 57 had lesions (50.4%) on the left side, and 56 (49.6%) on the right side. Young patients undergoing renal cancer surgery accounted for approximately 12.4% of the total number of renal cancer patients undergoing surgery, and nccRCC accounted for 34.8% of the total number of cases. 【Results】 Minimally invasive surgery (laparoscopic or robot-assisted) was performed in 102 cases (90.3%), and open surgery in 11 cases (9.7%). Fifty-five cases (48.7%) underwent partial nephrectomy and 58 (51.3%) radical nephrectomy. Among them, 11 patients (9.7%) developed tumor thrombi. All surgeries were successful with no serious complications. The pathological types included 32 cases (28.3%) of chromophobe renal cell carcinoma, 25 cases (22.1%) of MiT family translocation renal cell carcinoma, and 20 cases (17.7%) of papillary renal cell carcinoma. The total proportion of the three pathological subtypes reached 68.1%. After 46 (2-115) months of follow-up, 8 cases (7.8%, 8/102) developed tumor metastasis and 2 died. 【Conclusion】 The nccRCC is rare in young patients. The major pathological type is chromophobe, and the major treatment method is minimally invasive surgery. Most pathological types have good long-term prognosis, while patients with tumor thrombi have a high risk of metastasis and poor prognosis.

Objective: To investigate the effect of the AML1-ETO (AE) fusion gene on the biological function of U937 leukemia cells by establishing a leukemia cell model that induces AE fusion gene expression. Methods: The doxycycline (Dox) -dependent expression of the AE fusion gene in the U937 cell line (U937-AE) were established using a lentivirus vector system. The Cell Counting Kit 8 methods, including the PI and sidanilide induction, were used to detect cell proliferation, cell cycle-induced differentiation assays, respectively. The effect of the AE fusion gene on the biological function of U937-AE cells was preliminarily explored using transcriptome sequencing and metabonomic sequencing. Results: ①The Dox-dependent Tet-on regulatory system was successfully constructed to regulate the stable AE fusion gene expression in U937-AE cells. ②Cell proliferation slowed down and the cell proliferation rate with AE expression (3.47±0.07) was lower than AE non-expression (3.86 ± 0.05) after inducing the AE fusion gene expression for 24 h (P<0.05). The proportion of cells in the G(0)/G(1) phase in the cell cycle increased, with AE expression [ (63.45±3.10) %) ] was higher than AE non-expression [ (41.36± 9.56) %] (P<0.05). The proportion of cells expressing CD13 and CD14 decreased with the expression of AE. The AE negative group is significantly higher than the AE positive group (P<0.05). ③The enrichment analysis of the transcriptome sequencing gene set revealed significantly enriched quiescence, nuclear factor kappa-light-chain-enhancer of activated B cells, interferon-α/γ, and other inflammatory response and immune regulation signals after AE expression. ④Disorder of fatty acid metabolism of U937-AE cells occurred under the influence of AE. The concentration of the medium and short-chain fatty acid acylcarnitine metabolites decreased in cells with AE expressing, propionyl L-carnitine, wherein those with AE expression (0.46±0.13) were lower than those with AE non-expression (1.00±0.27) (P<0.05). The metabolite concentration of some long-chain fatty acid acylcarnitine increased in cells with AE expressing tetradecanoyl carnitine, wherein those with AE expression (1.26±0.01) were higher than those with AE non-expression (1.00±0.05) (P<0.05) . Conclusion: This study successfully established a leukemia cell model that can induce AE expression. The AE expression blocked the cell cycle and inhibited cell differentiation. The gene sets related to the inflammatory reactions was significantly enriched in U937-AE cells that express AE, and fatty acid metabolism was disordered.

In the context of the reform of group payment related to disease diagnosis, a tertiary first-class hospital focused on the needs of patients and guided by value-based healthcare, established a professional and normalized refined anti-tumor drug management system, setted up a multidisciplinary diagnosis and treatment team, and promoted " Internet plus pharmaceutical services" in December 2018.From 2019 to 2021, the proportion of hospital drugs were 30.8%, 30.1%, and 27.3%, respectively. The amount of money spent on anti-tumor drugs were 83.25 million yuan, 76.41 million yuan, and 62.48 million yuan, respectively, showing a decreasing trend year by year. The practice of refined management of anti-tumor drugs fully reflected the core concept of value based healthcare, achieving closed-loop management of the entire process of drugs, improving the level of rational drug use, reducing the economic burden on patients, and providing reference for improving the level of rational use of anti-tumor drugs in public hospitals.

This study aimed to provide scientific evidence for predicting quality markers(Q-markers) of Elephantopus scaber by establishing UPLC fingerprint of E. scaber from different geographical origins and determining the content of 13 major components, as well as conducting in vitro anti-cancer activity investigation of the main components. The chromatographic column used was Waters CORTECS UPLC C_(18)(2.1 mm×150 mm, 1.6 μm), and the mobile phase consisted of acetonitrile and 0.1% formic acid solution(gradient elution). The column temperature was set at 30 ℃, and the flow rate was 0.2 mL·min~(-1). The injection volume was 1 μL, and the detection wavelength was 240 nm. The UPLC fingerprint of E. scaber was fitted using the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine(2012 edition) to determine common peaks, evaluate similarity, identify and determine the content of major components. The CCK-8 assay was used to explore the inhibitory effect of the main components on the proliferation of lung cancer cells. The results showed that in the established UPLC fingerprint of E. scaber, 35 common peaks were identified. Thirteen major components, including neochlorogenic acid(peak 1), chlorogenic acid(peak 2), cryptochlorogenic acid(peak 3), caffeic acid(peak 4), schaftoside(peak 6), galuteolin(peak 9), isochlorogenic acid B(peak 10), isochlorogenic acid A(peak 12), isochlorogenic acid C(peak 18), deoxyelephantopin(peak 28), isodeoxyelephantopin(peak 29), isoscabertopin(peak 31), and scabertopin(peak 32) were identified and quantified, and a quantitative analysis method was established. The results of the in vitro anti-cancer activity study showed that deoxyelephantopin, isodeoxyelephantopin, isoscabertopin, and scabertopin in E. scaber exhibited inhibition rates of lung cancer cell proliferation exceeding 80% at a concentration of 10 μmol·L~(-1), higher than the positive drug paclitaxel. These results indicate that the fingerprint of E. scaber is highly characteristic, and the quantitative analysis method is accurate and stable, providing references for the research on quality standards of E. scaber. Four sesquiterpene lactones in E. scaber show significant anti-cancer activity and can serve as Q-markers for E. scaber.

OBJECTIVE: To retrospectively analyze clinical data of patients under 40 years old who underwent surgical treatment for renal tumors with tumor thrombus from January 2016 to December 2022 at Peking University Third Hospital, and to evaluate the surgical effect and investigate the relationship between clinicopathological characteristics and prognosis. METHODS: The clinical data of 17 young patients with renal tumor thrombus were retrospectively analyzed, and the clinicopathological features and prognosis were summarized. The patients were grouped according to the presence or absence of symptoms, 2017 American Joint Committee on Cancer (AJCC) clinical stage, and postoperative combined adjuvant therapy. Kaplan-Meier method was used to plot the survival curve, and Log-rank test was used to compare the differences in postoperative survival time and progression-free survival time between the different groups. The relationship between clinicopathological features and prognosis was analyzed. RESULTS: All the 17 patients received venous tumor thrombectomy, including 16 patients (94.1%) who underwent radical nephrectomy and 1 patient (5.9%) who underwent partial nephrectomy. Twelve patients (70.6%) had symptoms and 5 (29.4%) had no symptoms before operation. A total of 17 renal tumors were observed, with 2 patients (11.8%) identified as benign and 15 patients (88.2%) classified as malignant. Among the malignant tumors, 1 patient (6.7%) was diagnosed as clear cell carcinoma, while the remaining 14 patients (93.3%) were categorized as non-clear cell carcinoma. In terms of tumor stage, 8 patients (53.3%) were classified as stage Ⅲ according to the AJCC classification, while 7 patients (46.7%) were categorized as stage Ⅳ. Additionally, 6 patients (40%) received multiple adjuvant therapy, while 9 patients (60%) did not undergo such treatment. The follow-up period ranged from 2 to 78 months, with a median follow-up of 41 months. During this time, 3 patients (20%) died. The median survival time after surgery was 39.0 (2.3, 77.8) months, and the progression-free survival time was 16.4 (2.3, 77.8) months. There was no significant difference in postoperative survival time and progression-free survival time among young patients with renal tumor with tumor thrombus, based on the presence of symptoms before surgery (P=0.307, P=0.302), clinical stage of AJCC (P=0.340, P=0.492), and postoperative adjuvant therapy (P=0.459, P=0.253) group. CONCLUSION The pathological types of young patients with renal tumor with tumor thrombus are more complex and varied due to symptoms, and the proportion of non-clear cell carcinoma in malignant tumor with tumor thrombus is higher. Symptomatic and non-clear cell carcinoma may be potentially associated with poor prognosis. Surgical operation combined with adjuvant therapy is a relatively safe and effective treatment for young patients with renal tumor and tumor thrombus.

Three kinds of excipients were selected to investigate the anti-bitterness effect on the extremely bitter characteristics of Andrographis Herba decoction, and the optimal combined anti-bitterness formula was obtained. The preparation principle of different excipients was clarified by virtual screening and experimental verification to explore the advantages of the three kinds of excipients in the combined anti-bitterness effect. Sensory evaluation showed that mPEG_(2000)-PLLA_(2000), γ-cyclodextrin(γ-CD), and aspartame all had good anti-bitterness effect, which reduced the bitterness intensity of Andrographis Herba decoction by 0.5, 6, and 3 points, respectively. The anti-bitterness effect was superior when 0.15% mPEG_(2000)-PLLA_(2000), 1.60% γ-CD, and 0.04% aspartame were combined, and the taste score of the Andrographis Herba decoction decreased from 8 points(severe bitterness) to 1 point(almost no bitterness). Quantum chemistry calculations showed that mPEG_(2000)-PLLA_(2000) reduced the electrostatic potential of bitter groups, which spontaneously combined with it and formed a physical barrier, hindering the binding of bitter components to receptors. The interaction between γ-CD and bitter components was studied. It was found that the surface area and free energy of γ-CD decreased and the dipole moment increased, indicating that γ-CD included bitter components and self-assembled to form supramolecules. Molecular docking showed that hydroxy at position 14 and carbonyl at position 16 of andrographolide, and hydroxy at position 3 and 4, carbonyl at position 14, and five-membered lactone ring of dehydrated andrographolide were possibly the main bitter groups. The binding free energies of aspartame to bitter receptors TAS2 R10, TAS2 R14, and TAS2 R46 were-3.21,-1.55, and-2.52 kcal·mol~(-1), respectively, indicating that aspartame competed to inhibit the binding of bitter groups to bitter receptors. The results of content determination showed that the free amounts of andrographolide and dehydrated andrographolide in Andrographis Herba decoction were 0.23% and 0.28% respectively, while after adding flavor masking excipients, the dissociation amount of andrographolide and dehydrated andrographolide in the decoction decreased to 0.13% and 0.20%, respectively. The above results show that mPEG_(2000)-PLLA_(2000) involves some bitter components into it through micellar self-assembly to reconcile the entrance bitterness, and γ-CD includes the remaining bitter components in the real solution to control the main bitter taste. Aspartame further competes to inhibit the combination of bitter components and bitter receptors, and improves the taste to be sweet. Multi-excipients combined with anti-bitterness strategy significantly reduces the free concentration of bitter substances in Andrographis Herba decoction, and optimizes the taste of the decoction.
