RESUMO
Solitary fibrous tumor is a rare mesenchymal tumor associated with NAB2-STAT6 fusion gene, which is rarely seen in kidney. A 16-year-old boy was hospitalized because of left back pain for more than 3 years. Abdominal CT/MRI identified a huge space-occupying lesion in the left kidney. Laparoscopic radical left nephrectomy was performed initially. Nevertheless, laparoscopic-to-open procedure was adopted due to the huge size of the tumor. The pathological diagnosis was renal solitary fibrous tumor. The symptoms of the patient disappeared and no recurrence was observed at the 2-month follow-up after the surgery.

RESUMO
@#The study aims to investigate different pharmacokinetic profilesof anthraquinones after oral administration of Rhei Radix et Rhizoma and Niuhuang Jiedu Tablets(NHJDT)in rats, respectively. Rats were administrated with 96 mg/kg of Rhei Radix et Rhizoma(1. 83 mg/kg of total anthraquinone, equivalent to 0. 28 mg/kg of rhein, 0. 30 mg/kg of emodin, 0. 81 mg/kg of chrysophanol, 0. 23 mg/kg of aloe-emodin and 0. 20 mg/kg of physcion)or 250 mg/kg of NHJDT(equal dose of total anthraquinone as Rhei Radix et Rhizoma, equivalent to 0. 33 mg/kg of rhein, 0. 38 mg/kg of emodin, 0. 71 mg/kg of chrysophanol, 0. 24 mg/kg of aloe-emodin and 0. 17 mg/kg of physcion), respectively. Followed by protein precipitation with methanol, the anthraquinones in plasma samples were determined by LC-MS/MS. The pharmacokinetic parameters were calculated by WinNonlin 7. 0. The cmaxof rhein were(121±103)and(474±251)μg/L, and the AUC0-twere(275±176)and(406±194)μg ·h/L for Rhei Radix et Rhizoma and NHJDT, respectively. The cmaxof chrysophanol isomer were(2 325±1 390)and(3 580±2 169)μg/L, and the AUC0-twere(8 170±2 661)and(8 856±4 023)μg ·h/L, respectively. Emodin in very low levels was only detected in rat plasma samples after oral gavage of NHJDT. The cmax, AUC and t1/2 of rhein, as well as Vd and CL of chrysophanol isomer were observed with a much increased degree in comparison with Rhei Radix et Rhizoma counterparts. However, much shorter tmaxwas found in NHJDT group. Therefore, NHJDT with co-existing components enhanced the absorption and influenced the pharmacokinetic behaviors of active ingredients in Rhei Radix et Rhizoma.
RESUMO
Objective To investigate the association between interleukin-17 A (IL-17 A) gene promoter polymorphism and blood lipid and inflammatory factors in coronary heart disease.Methods A total of 241 patients with coronary heart disease who were admitted to hospital from April 2010 to December 2016 were enrolled in this study.68 cases of healthy subjects were collected.IL-17 gene promoter rs8193036 genotype,blood lipid and inflammatory factors were detected and compared.Results Compared with the control group,the genotype CC,CT and TT of the rs8193036 genotype in the coronary heart disease group were significantly different (P＜0.05),and the frequency of C allele in the coronary heart disease group was significantly higher than that in the control group (P＜0.05).The levels of triglyceride,low-density lipoproteinCholesterol,high density lipoprotein cholesterol,interleukin-17a,interleukin-6,interleukin-8 and tumor necrosis factor alpha in CC genotype of tumor necrosis factor alpha group were significantly higher than those in tumor necrosis factor alpha group (P＜0.05),high density lipoprotein cholesterol decreased significantly (P＜0.05).Total cholesterol and low-density lipoprotein cholesterol had no significant differences (P ＞ 0.05).Conclusion The rs8193036 polymorphism of IL-17A gene promoter is associated with the pathogenesis of coronary heart disease.The C allele is an important genetic marker of coronary heart disease.The polymorphism of IL-17A promoter rs8193036 might affect coronary heart disease by increasing blood lipids and inflammation factors.
RESUMO
BACKGROUND: Cardiac stem cells can differentiate into cardiomyocytes in vitro under induction of pilose antlerpolypeptides, which provides a new therapeutic idea for myocardial injury.OBJECTIVE: To explore the effect of pilose antler polypeptides on the apoptosis rate and membrane stability ofmitochondria in cardiac stem cells.METHODS: We chose healthy male Wistar rats born 2 days to extract cardiac stem cells. The culture dish was used asthe experimental unit, and extracted cells were divided into the following four groups (n=12). Blank control group: Thesame amount of buffer was added for induction; 5-azacytidine group: induced with 5-azacytidine (3 μmol/L); pilose antlerpolypeptides group: induced with pilose antler polypeptides (800 mg/L); combined group: induced with pilose antlerpolypeptides (800 mg/L) and 5-azacytidine (3 μmol/L). After 48 hours induction, apoptosis rate of cardiac stem cells ineach group was detected with flow cytometry. The membrane potential of mitochondria in cardiac stem cells wasdetected with immunofluorescence. The expression level of Nkx 2.5, GATA4, ATF-2, and MEF-2C in cardiac stem cellswas detected using western blot assay.RESULTS AND CONCLUSION: There were small, round and bright cells after 2 weeks culture, and cell colonies ofcardiac stem cells formed. The apoptosis rate of cardiac stem cells in the 5-azacytidine group increased significantly (P 0.05). The expression level of MEF-2C in each group was at a middle level, and there were no significantdifferences among groups (P > 0.05). To conclude, our experimental findings indicate that pilose antler polypeptidescould decrease the apoptosis rate and improve membrane stability of mitochondria in cardiac stem cells. Themechanism may be related to the increased expression of Nkx 2.5, but whether the mechanism is related to GATA4,ATF-2 and MEF-2C needs to be further studied.

Objective To study the efficacy and safety of intravesical chemotherapy combined with intravenous chemotherapy for high grade T1 (T1G3) bladder cancer after transurethral resection of bladder tumor(TURBT).Methods From January 2012 to December 2015,111 patients with high grade T1 (T1 G3) bladder cancer were retrospectively reviewed.Thirty-six patients received TURBT and intravesical chemotherapy and intravenous chemotherapy (group A),75 patients received TURBT and intravesical chemotherapy(group B).In group A,there were 28 males and 8 females,with average age 66.2 years;in group B,there were 59 males and 16 females,with mean age 67.9 years.There was no statistical difference between the two groups in age,sex,smoking history,tumor diameter,tumor number.1-year recurrence-free survival (RFS),1-year progression-free survival (PFS),intravenous chemotherapy adverse reaction were analyzed.Results All the patients were followed-up for 12 months.9 patients relapsed in group A,1-year RFS rate 75％,and the median RFS of the 9 patients was 9 (3-11) months.36 patients relapsed in group B,1-year RFS rate 52％,and the median RFS of the 36 patients was 7 (3-11) months.There was statistically significant difference between the two group(P =0.02).One patient progressed in group A,1-year PFS rate 97.2％,and the PFS was 9 months.Six patients progressed in group B,1-year PFS rate 92％,and the median PFS was 9.5(6-12) months.There was no statistically significant difference (P =0.305) between the two group.Only 1 case (3％) appeared Ⅲ° or above intravenous chemotherapy adverse reaction.Conclusions Intravesical chemotherapy combined with intravenous chemotherapy offers a better RFS rate than the intravesical chemotherapy alone for patients with T1G3 bladder cancer after TURBT,and there are very low rates of serious side effects.Intravenous chemotherapy may be considered as a new therapy strategy for T1G3 bladder cancer after TURBT.
RESUMO
A sensitive and selective method was developed for the separation and characterization of related substances (RSs) in EVT-401 by hyphenated LC–MS techniques. Complete separation of the RSs was achieved with an Inertsil ODS-SP column (250 mm×4.6 mm, 5 μm) by linear gradient elution using a mobile phase consisting of 0.2% formic acid solution, methanol and acetonitrile. EVT-401 was found to be susceptible to acid, alkaline and oxidative stresses, while relatively stable under photolytic and thermal dry stress conditions. Fourteen RSs including six process-related substances and eight degradation products were detected and identified in EVT-401 with positive ESI high-resolution TOF-MS analysis of their parent ions and the corresponding product mass spectra elucidation, and some of them were further verified by chemical synthesis and NMR spectroscopy. The specific LC–MS method developed for separation, identification and characterization of RSs is valuable for EVT-401 manufacturing process optimization and quality control.
