Objective To evaluate the safety and efficacy of dosage-escalated sorafenib in pa-tients with metastatic renal cell carcinoma. Methods Twelve male patients and 4 female patients with median age of 53 (37-71 years) were included in this study. They were with refractory meta-static renal-clear-cell carcinoma and received sorafenib from 800 mg/d to 1200mg/d or 1800 mg/d gradually until intolerable or disease progression occurred. Overall response rate, toxicity and progres-sion free survival (PFS) were recorded and analyzed. Results The median follow-up was 11 months (9-16 months). The overall rate of objective response and disease control rate were 44%(7/16)and 81%(13/16), respectively. Serious adverse effects (≥Grade Ⅲ) included hand-foot skin reaction (25%, 4/16), mucositis (19%, 3/16), diarrhea (19%, 3/16), hypertension (12%, 2/16) and my-elosuppression (12%, 2/16). PFS for high risk patient was 9.2 months at the end of this study. Conclusions The dosage-escalated sorafenib could obtain a high response rate and prolong PFS of high-risk patients. The toxicities are tolerable for metastatic renal cell carcinoma patients treated with sorafenib.

AIM: To investigate the effect of ischemic preconditioning(IPC) on expression of nitric oxide synthase(NOS) in rat smallfor-size liver graft and its significance.METHODS: Sixty SD rats were randomly divided into 3 groups(n=10 pairs/group): nonwarm ischemia group(NWI);warm ischemic group(WI);and ischemic preconditioning group(IPC).The models of rat small-for-size liver transplantation were set up by two-cuff technique.Expression of eNOS mRNA and iNOS mRNA in hepatic tissue were detected by fluorescence-quantitating-PCR.RESULTS: Heptic expression of eNOS mRNA post-IPC was higher than that pre-IPC(P0.05).It was higher in IPC group than that in NWI and WI group(P

Objective: To explore the correlation between umbilical artery blood erythropoietin (EPO) level and perinatal factors in premature infants and its clinical significance. Methods: Umbilical artery blood samples from 107 premature infants born in the Eastern Branch of Shanghai First Maternity and Infant Hospital of Tongji University between Jan. 2019 and Jun. 2019 were collected. The levels of EPO and ferritin were measured by ELISA and chemiluminescence assay, respectively. The 107 infants were divided into three groups according to the quartile EPO level: low level group, medium level group and high level group. The relationship between umbilical artery blood EPO level and gestational age, birth body mass and other perinatal factors, the incidence of anemia of prematurity (AOP), necrotizing enterocolitis (NEC), patent ductus arteriosus (PDA) and atrial septal defect (ASD) in premature infants, and the clinical characteristics of pregnant mothers was analyzed. Results: The EPO level of umbilical artery blood in 107 newborn premature infants was 5.94-137.18 mU/mL, and the median level was 23.51 (14.60, 51.28) mU/mL. There were 26 cases in the low level group (the EPO level 14.60 mU/mL), 54 in the medium level group (14.60-51.27 mU/mL), and 27 cases in the high level group (≥51.28 mU/mL). Univariate analysis showed that the gestational age of the infants in the low level group was significantly lower than those in the medium level group and the high level group (both P < 0.05), the age of the pregnant mothers was significantly higher than those in the medium level group and the high level group (both P < 0.05), the natural pregnancy rate was significantly lower than that in the high level group (P < 0.05), and the continuous positive airway pressure (CPAP) usage rate of the infants was significantly higher than that in the medium level group (P < 0.05). The ferritin level of umbilical artery blood was significantly higher in the midium level group than that in the high level group (P < 0.05). The incidence of AOP in the high level group was significantly higher than that in the midium level group (P < 0.05). Multiple linear regression analysis showed that the EPO level of umbilical artery blood was positively correlated with the gestational age of newborn premature infants and the natural pregnancy rate of pregnant mothers (both P < 0.01). Multivariate logistic regression analysis showed that the higher the natural pregnancy rate, the higher the level of EPO in umbilical artery blood, and the higher the natural delivery rate, the lower the level of EPO in umbilical artery blood. The risks of PDA and NEC decreased and the risk of ASD increased with the increase of EPO level in umbilical artery blood (all P < 0.05). Conclusion: Conception method and delivery mode are the influencing factors of EPO level in umbilical artery blood. Monitoring the EPO level of umbilical artery blood is helpful to diagnose the common complications such as AOP, PDA, ASD and NEC in premature infants.

Objectives To analyze the diagnosis and management of steroid-resistant nephrotic syndrome (SRNS) accompanied with irreversible leukoencephalopathy in children. Methods The clinical, laboratory and imaging data were retrospectively analyzed in a SRNS child accompanied with irreversible leukoencephalopathy. A literature review was performed. Results After clinical diagnosis of SRNS, glucocorticoid, immunosuppressant, and hemodialysis were administrated for 10 months. During the course of treatment, the seizures, visual problems, and hypertension were repeatedly occured. The cranial MRI showed bilateral occipital parietal lobe hyperintensity and right frontotemporal lobe hyperintensity on T2-weighted imaging and bilateral occipital parietal lobe hypointensity on T2-Flair imaging, which indicated that encephalomalacia was accompanied with gliosis. Conclusions A variety of reasons may induce leukoencephalopathy in children. The accompanied irreversible leu-koencephalopathy should be strongly considered in management of SRNS.

Objective To investigate the optimal window width and window level for measuring the airway dimensions with spiral CT scan in Japanese white big-ear rabbits so as to lay the foundation for airway stenting in animal experiments. Methods Multi-slice spiral CT scanning of cervico-thoracic region was performed in 30 healthy adult Japanese white big-ear rabbits, the anteroposterior and transversal diameter of the thoracic trachea, the anteroposterior diameter of the right and left bronchus were measured with lung window, mediastinum window and special fat window separately. The revealing rate of the tracheal wall and the measuring results in different windows and levels were recorded and compared with the anatomical data. The differences of the relevant data were statistically analyzed. Results With lung window, the tracheal wall was well demonstrated, but the relevant data were smaller than that with mediastinum window. With mediastinum window, the data were bigger and the tracheal wall border appeared blurred. The results obtained with fat window were close to the actual anatomical data. Conclusion For accurately measuring the anteroposterior and transversal diameter of the thoracic trachea in Japanese white big-ear rabbits with multi-slice spiral CT scan, fat window should be adopted, which is helpful for the preparation of tracheal and bronchial stents.

Aim To investigate the antitumor and antiangiogenic effects of combined low-dose cyclophosphamide(CTX)and recombined VEGF protein vaccine.Methods In this experiment,H22 hepatocellular carcinoma model was established in BALB/c mice.Mice were randomly divided into four groups: control group,CTX group(CTX),VEGF protein vaccine group(V2)and CTX plus V2 group(CTX+V2).The anti-tumor efficacy and antiangiogenic effect were investigated using a subcutaneous tumor model and an intradermal tumor model.Western blot and ELISAwere further adopted to detect the specific anti-VEGF antibody.Results CTX+V2 group displayed a lower tumor volume and tumor weight than either the single therapy group in the subcutaneous tumor model(P<005 vs V2,P<001 vs CTX).Meanwhile,CTX+V2 was more effective for antagonizing tumor-associated angiogenesis compared with either the single therapy(P<005 vs V2,P<001 vs CTX).After CTX+V2 immunization,high titer of anti-VEGF antibody was detected by ELISA and verified by Western blot.Conclusion The therapy of CTX combined with V2 has significant synergistic effect against H22 hepatocellular carcinoma.

AIM: To investigate the molecular mechanism by which hypoxia affect the endothelial nitric oxide synthase (eNOS) expression in cerebral artery endothelial cells (CAECs). METHODS: Primary cultured porcine CAECs were exposed to hypoxia for 2 h, 6 h, 12 h, 24 h and 48 h. The eNOS mRNA level was determined by RT-PCR. The level of eNOS protein was detected by Western blotting. After specific PKC inhibitors BIM Ⅰ(1 ?mol/L) and G6983 (1 ?mol/L) were added, CAECs were exposed to hypoxia for 24 h. The effect of hypoxia on eNOS mRNA stability was analyzed after actinomycin D was added. RESULTS: After exposure to hypoxia for 2 h, the levels of eNOS mRNA and protein in CAECs were increased. The levels of eNOS mRNA and protein reached peak after 12 h of hypoxia (about 2 5 fold and 2 0 fold, respectively, compared to control), and remained at higher level even after 48 h of hypoxia. Moreover, hypoxia did not change the stability of eNOS mRNA. The specific PKC inhibitors BIM Ⅰ and G6983 attenuated significantly the effects of hypoxia on eNOS gene expression. CONCLUSION: These results suggest that hypoxia may enhance the expression of eNOS gene in CAECs through PKC signaling pathway, which might be one of the mechanisms of cerebral artery dilation and neuroprotection during cerebral hypoxia.
