OBJECTIVE To screen the optimal compatibility ratio of Gentiana straminea Maxim.(G.S Maxim) and Rhodiola crenulata (Hook. f. et Thoms.) H. Ohba(R. crenulata), and explore its anti-hypoxia effect and possible mechanism through in vivo and in vitro experiments and network pharmacology. METHODS PC12 cells were divided into groups, and the cell hypoxia model was established by Na2S2O4, H2O2 and physical hypoxia methods, and the compatibility ratio of G.S Maxim-R. crenulata was initially screened. Eighty SPF male Kunming mice were randomly divided into blank group, model group, positive group, and different compatibility ratio groups of G.S Maxim-R. crenulata(2:8, 3:7, 4:6, 5:5, 6:4, 7:3, 8:2), with 8 mice in each group. Gastric drug delivery in 15 d in advance, in addition to the blank group, the rest of the groups were normal pressure hypoxia experiments. Groups of mice survival time was recorded. Detected the levels of inflammatory cytokines, MDA content, and SOD activity in the lung tissues of mice in the blank group, model group, positive group, G.S Maxim-R. crenulata 4:6 group and 3:7 group. The anti-hypoxia mechanism of G.S Maxim-R. crenulata was investigated by network pharmacology and molecular docking, and verified by qPCR. RESULTS In vitro experiments showed that G.S Maxim-R. crenulata had better anti-hypoxia activity. In vivo experimental results showed that the combination ratio of G.S Maxim-R. crenulata with 4:6 and 3:7 could significantly improve the survival time of mice, reduce the contents of NF-κB, IL-6, IL-1β and MDA in lung tissue, and increase the content of IL-10 and SOD activity, and the effect of G.S Maxim-R. crenulata 3:7 group was the best. Network pharmacological studies showed that the potential active components of G.S Maxim-R. crenulata in anti-hypoxia might be ursolic acid, oleanolic acid, and ethyl gallate, etc. The core targets included SRC, PIK3CA, MAPK3, etc., and its anti-hypoxia signaling pathways mainly included PI3K-Akt, HIF-1, etc. The results of qPCR showed that G.S Maxim-R. crenulata could increase the expression of PI3K, Akt, mTOR and p62 in the lung tissue of hypoxic mice. Molecular docking verification showed that the core targets SRC, PIK3CA, and p62 had good binding activity with potential active components such as oleanolic acid, kaempferol, ethyl gallate and quercetin. CONCLUSION G.S Maxim-R. crenulata has anti-hypoxia activity, which may be related to PI3K/Akt signaling pathway through anti-inflammatory, anti-oxidative stress and regulation of autophagy.

Objective:To evaluate the diagnostic value of contrast-enhanced ultrasound(CEUS) in renal atypical space occupying lesions.Methods:The images of conventional ultrasound and CEUS in 44 patients with 47 renal atypical space occupying lesions from May 2015 to June 2019 were retrospectively analyzed, including 26 males and 18 females. The mean age of patients was(55.9±13.7)years old, ranged from 27 to 79 years old. The mean size of the lesions in conventional ultrasound was (2.5±1.3)cm, ranged from 1.0 to 6.0 cm. The location, size, echo, boundary and color flew signals of renal lesions were observed by conventional ultrasound.The degree and the pattern of enhancement, presence or absence of a clear capsule sign were analyzed by CEUS. The ultrasound diagnosis results were compared with the pathological or clinical diagnosis.Results:Of the 47 lesions, 15 were malignant and 32 were benign. 19 lesions were diagnosed by operation pathology, including 13 renal cell carcinomas, 2 renal lymphomas, 3 renal cysts and 1 inflammatory granuloma; the other 28 benign tumors or pseudotumors were diagnosed by enhanced CT or MRI, and were followed up for more than 1 year, including 5 angiomyolipomas, 15 cysts, 3 renal junction cortex defects, 2 renal column hypertrophies, 1 local non-atrophic renal parenchyma, 1 hump kidney and 1 scar. Most of the renal cell carcinomas were hypoechoic (8/13), "fast wash-in and fast wash-out " (9/13), heterogeneous hypoenhancement (6/13), 9 with pseudocapsule and 6 with necrosis. 2 renal lymphomas were hypoechoic, "fast wash-in and fast wash-out" , 1 isoenhancement and 1 hypoenhancement. The angiomyolipomas were hyperechoic, "slow wash-in and slow wash-out" (4/5), 2 hypoenhancement, 2 hyperenhancement and 1 isoenhancement. Most renal cysts were anechoic(16/18). There was no enhancement in simple renal cysts. The wall or septum of complex renal cysts was thin and homogeneous enhanced, showing "slow wash-in and slow wash-out" with isoenhancement or hypoenhancement. Inflammatory granuloma was cystic-solid. The solid part was hypoenhancement. Renal column hypertrophy, hump kidney and local non-atrophic renal parenchyma were hypoechoic, showing the same enhancement pattern as renal parenchyma by CEUS. The junctional parenchyma defect and renal scar were hyperechoic, showing no enhancement. The sensitivity, specificity, accuracy and the area under the ROC curve of conventional ultrasound and CEUS in the diagnosis of benign and malignant lesions were 86.7%, 87.5%, 87.2%, 0.871 and 100.0%, 96.9%, 97.9%, 0.984.There were significant differences in the diagnosis of renal atypical space occupying lesions between two methods ( P=0.03). Conclusions:CEUS was better than conventional ultrasound in the diagnosis of renal atypical space occupying lesions. CEUS had advantages in the differential diagnosis of benign and malignant tumors, benign lesions and anatomical variants mimicking a renal tumor.

Objective: To verify the safety and efficacy of IONTRIS particle therapy system (IONTRIS) in clinical implementation. Methods: Between 6.2014 and 8.2014, a total of 35 patients were enrolled into this trial: 31 males and 4 females with a median age of 69 yrs (range 39-80). Ten patients had locally recurrent head and neck tumors after surgery, 4 cases with thoracic malignancies, 1 case with hepatocellular carcinoma, 1 case with retroperitoneal sarcoma, and 19 cases with non-metastatic prostate carcinomas. Phantom dose verification was mandatory for each field before the start of radiation. Results: Twenty-two patients received carbon ion and 13 had proton irradiation. With a median follow-up time of 1 year, all patients were alive. Among the 16 patients with head and neck, thoracic, and abdominal/pelvic tumors, 2, 1, 12, and 1 cases developed complete response, partial response, stable disease, or disease progression, respectively. Progression-free survival rate was 93.8% (15/16). Among the 19 patients with prostate cancer, biological-recurrence free survival was 100%. Particle therapy was well tolerated in all 35 patients. Twenty-five patients (71.4%) experienced 33 grade 1 acute adverse effects, which subsided at 1 year follow-up. Six (17.1%) patients developed grade 1 late adverse effects. No significant change in ECOG or body weight was observed. Conclusions IONTRIS is safe and effective for clinical use. However, long term follow-up is needed to observe the late toxicity and long term result.
