Objective To evaluate the clinical efficacy of endourologic treatment of benign uret-erointestinal anastomotic strictures in patients with urinary diversion. Methods Nine cases of benign ureterointestinal anastomotic strictures with a length of 1-3 cm following radical cystectomy and uri-nary diversion accepted endourologic treatment. 8 cases were treated by antegrade percutaneous ap-proach, 1 case by retrograde ureteroscopic approach. The strictures received balloon dilation, and ure-teral stents indewelled. Results In a follow up of 0.5-5.0 years, 1 case received percutaneous ne-phrostomy for complete ureterointestinal anastomotic atresia and refused to open operation reconstruc-tion. 5 cases had no recurrence after 2-3 endoscopic sessions. 3 cases needed long time ureteral stents indwelled. Conclusion Endourological technique for ureterointestinal strictures following urinary di-version avoided the disadvantages of open operation.

Objective: To assess the effect of balloon angiopl asty on circulating endothelin (ET) and TNF-α levels and tissue endothelin in experimental atherosclerosis in rabbits. Methods: After 20 New Z ealand rabbits had a high cholesterol diet for at least 8 weeks, successful ball oon angioplasty was performed in rihgt iliac arteries in 18 rabbits. Circulatin g levels of ET and TNF-α were measured before as well as immediately and 24 h after balloon angioplasty. Tissue endothelin immunoreactivity in atherosclerotic iliac artery wall after balloon angioplasty was assessed by immunohistochemica l technique. Results: Plasma levels of ET and TNF-α were signi ficantly increased immediately after ballon angioplasty (76.40±13.58)pg/ml vs (92.67±11.38) pg/ml and (31.35±6.23) U/ml vs (56.26±7.37) U/ml, resp ectively (P<0.05) .There was no change in plasma ET and TNF-α levels 24 h after balloon angioplasty (77.13±12.87) pg/ml vs (76.40±13.58) pg/ml and (33.41±6.79) U/ml vs (31.35±6.23) U/ml, respectively (P>0.05). T issue endothelin immunoreactiuvity was markedly increased in right iliac artery wall after balloon angioplasty than that in opposite iliac artery wall. Conclusion: The increase of plasma ET, TNF-α levels and tissue ET-IR in iliac artery wall after balloon angioplasty may be associated with the injury of l ocal vascular intima, suggesting that ET and TNF-α may take part in the corona ry constriction and the development of coronary restenosis after percutaneous tr ansluminal coronary angioplasty.

Objective:To observe the effect of percutaneous tr ansluminal coronary angioplasty (PTCA) on coronary circulating tumor necrosis fa ctor-α (TNF-α) activity. Methods: Plasma TNF-α levls were measured with radioimmunoassay and bioactive assay respectively. Result s: Plasma TNF-α activity in femoral artery (AO) was significantly incr eased immediately after PTCA [(15.86±3.75) U/ml vs (41.32±4.36) U/ml, P<0.01], and plasma TNF-α activity in coronary sinus was remarkably incre ased immediately after PTCA [(16.72±4.14) U/ml vs (65.61±6.25) U/ml, P<0.01]. There was no change in plasma TNF-α activity in AO 24 h after PT CA [(18.32±5.12) U/ml vs (15.86±3.75) U/ml, P>0.05]. Conclu sion: The increase in plasma TNF-α activity after PTCA may be associat ed with the injury of coronary artery caused by PTCA, suggesting that TNF-α ma y be involved in the coronary occlusion and the development of coronary restenos is after PTCA.

OBJECTIVETo observe metabolomic changes in urine of chronic superficial gastritis (CSG) patients with Pi-qi deficiency syndrome (PQDS) or Pi-Wei dampness-heat syndrome (PWDHS), thereby providing scientific evidence for syndrome typing of them.
METHODSUrine samples were collected from CSG patients with PQDS/PWDHS and healthy volunteers, 10 in each group. Proton nuclear magnetic resonance spectroscopy (1H-NMR) based metabonomic analysis was performed on urine samples. Contents of related biomarkers were analyzed by principal component analysis (PCA), partial least square discriminant analysis (PLS-DA), and urivariate statistical analysis.
RESULTSPLS-DA analysis showed that metabolites among CSG patients with PQDS/PWDHS and healthy volunteers could be mutually distinguished. Seven differentially identified metabolites were screened from urines of CSG patients with PQDS and healthy volunteers included glutamate, methionine, α-oxoglutarate, dimethylglycine, creatinine, taurine, and glucose. Four differentially identified metabolites were screened from urines of CSG patients with PWDHS and healthy volunteers included 2-hydroxybutyric acid, trimethylamine oxide, taurine, and hippuric acid. Eleven differentially identified metabolites were screened from urines of CSG patients with PQDS and PWDHS included fucose, β-hydroxybutyric acid, alanine, glutamate, methionine, succinic acid, citric acid, creatinine, glucose, hippuric acid, and lactic acid.
CONCLUSIONThe metabolic differences of CSG patients PQDS and PWDHS mainly manifested in glycometabolism, lipid metabolism, and amino acids catabolism, and 1H-NMR based metabonomics may be used in classified study of Chinese medical syndrome typing.

OBJECTIVETo investigate the effect of tranilast on myocardial fibrosis in mice with viral myocarditis (VMC).
METHODSMale balb/c mice (n=72) were randomly divided into control, VMC and tranilast groups (n=24 each). In the VMC and tranilast groups, the mice were infected with Coxsackie virus B3 (CVB3) to prepare VMC model, while the control group was treated with Eagle's medium. After modeling, the tranilast group was administrated with tranilast [200 mg/(kg.d)] until the day before sampling. On days 7, 14 and 28 after CVB3 or Eagle's medium infection, heart specimens (n=8) were taken and examined after Toluidine blue staining and Nissl staining for counts of mast cells (MC), hematoxylin-eosin staining for myocardial pathological changes, and Masson staining for myocardial fibrosis. The expression of CTGF and type I collagen (Col I) in the myocardial tissue was measured by RT-PCR and Western blot. The correlations of CTGF mRNA expression with MC counts and Col I expression were analyzed.
RESULTSThe myocardial pathological changes and collagen volume fraction in the VMC group were significantly higher than in the control group at all three time points (P<0.05). Tranilast treatment significantly decreased the myocardial pathological changes and collagen volume fraction compared with the VMC group (P<0.05). The mRNA and protein expression of CTGF and Col I increased in the VMC group compared with the control group, and the increases were reduced with tranilast treatment (P<0.05). The number of MC was positively correlated to CTGF mRNA expression on the 7th day and 14th day (r=0.439, P=0.049) in the VMC group. There were positive correlations between the mRNA expression of Col I and CTGF on the 7th day and 14th day (r=0.646, P=0.007) and the 28th day (r=0.326, P=0.031).
CONCLUSIONSTranilast may inhibit the aggregation of MC and down-regulate the expression of CTGF, relieving myocardial fibrosis of mice with VMC.

Objective: To evaluate the tolerance and safety of a human-mouse chimeric anti-CD20 monoclonal antibody IBI301 in Chinese patients achieved objective response with CD20(+) B-cell non-Hodgkin's lymphoma (NHL). Methods: Nine patients with CD20(+) B-cell NHL received dose-escalating IBI301 infusions (250 mg/m(2), n=3; 375 mg/m(2), n=3; 500 mg/m(2), n=3, respectively). The data of all patients were collected for safety analyses. The median exposures of 125 mg/m(2), 375 mg/m(2), 500 mg/m(2) dose groups were 243, 690 and 980 mg, respectively. Safety and tolerability were evaluated by monitoring adverse events (AE). The ratios of CD19(+), CD20(+) B cells and the levels IgG and IgM were detected to evaluate the pharmacodynamics. Results: Totally 52 events of AE were observed, including 18 events of AE in 125 mg/m(2) group, 14 events of AE in 375 mg/m(2) group and 20 events of AE in 500 mg/m(2) group, respectively. There were 26 adverse reactions of 52 cases of AE, 22 reactions were judged to be probably related to IBI301, and 4 reactions were not probably related to IBI301, all disappeared or returned to baseline levels. Common AE in this study included decreased WBC, upper respiratory infection, decreased neutrophil count, dyspepsia, hyperuricemia, paresthesia, oral mucositis and dizziness. No patients quitted or trial discontinued. No severe AE (SAE) were reported. No dose-limiting toxicity (DLT) events were observed in the study. The ratio of CD20(+) and CD19(+) B cells decreased in all subjects. There was no significant changes of the levels of IgG and IgM. Conclusions: The single dose of IBI301 injection was well tolerated, and the AE occurred in the patients recovered. No SAE were reported, No DLT events were observed in the study. The IBI301 caused an elimination of the peripheral CD20-expressing B cells in all patients. Clinical trial registration: Chinadrugtrials, CTR20140762.

OBJECTIVETo study the genetic aberrations of ocular extranodal marginal zone B-cell lymphomas of mucosa-associated lymphoid tissue (MALT) type occurring in patients from southern China.
METHODSFifty seven paraffin-embedded ocular MALT lymphoma specimens from patients in southern China were studied by interphase fluorescence-in-situ hybridization (FISH) for genetic aberrations including t(11;18)(q21;q21)/API2-MALT1, t(1;14)(p22;q32)/IgH-bcl-10, t(14;18) (q32;q21)/IgH-MALT1 and bcl-6/FOXP1 gene translocations.
RESULTSAmongst the 57 cases studied, 9 cases (15.8%) showed chromosome translocations, including 4 cases (7.0%) of t(11;18)(q21;q21)/API2-MALT1, 1 case (1.8%) of t(14;18) (q32;q21)/IgH-MALT1, 1 case (1.8%) of bcl-6 gene-related chromosome translocation and 3 cases (5.3%) of IgH-unknown translocation partner. FISH revealed 17 cases (29.8%) with 3 copies of bcl-6 gene, 21 cases (36.8%) with 3 copies of MALT1 gene and 12 cases (21.1%) with 3 copies of both genes.
CONCLUSIONSThe MALT lymphoma-associated chromosome translocations t(11;18)(q21;q21)/API2-MALT1 and t(14;18) (q32;q21)/IgH-MALT1 are demonstrated in ocular MALT lymphomas of southern Chinese patients. The prevalence is significantly different from that reported in northern Chinese and northern American patients, indicating a geographic heterogeneity in the MALT lymphoma-associated genetic aberrations. The presence of 3 copies of bcl-6 and MALT1 genes is the commonest genetic abnormalities observed in ocular MALT lymphomas, suggesting a possible role in MALT lymphomagenesis.

The present study was aimed to investigate the effects of ginsenoside Rb1 on okadaic acid (OA)-induced Tau hyperphosphorylation in hippocampal neurons of Sparague-Dawley rat and to explore its possible mechanism. Animals were randomly divided into four groups. Group 1 received dimethysulphoxide (DMSO) injection (vehicle group), group 2 only received OA injection (OA group), group 3 was pretreated with Rb1 and then received OA injection (Rb1 pretreatment group), and the group 4 was an intact control group. The animals in group 3 were injected intraperitoneally with various doses of Rb1 at 5, 10, and 20 mg/kg (once a day for 14 d). On the thirteen day of pretreatment, animals in Rb1 pretreatment group as well as animals in OA group received a bolus injection of 0.483 microg of OA (1.5 microl of solution in DMSO) at right dorsal aspect of hippocampus to induce Tau hyperphosphrylation. The brains were harvested one day after the last treatment. In all groups, the morphology of neurofibrils, phosphorylation of Tau protein, and the activity of phosphatase 2A (PP2A) were investigated. In OA group, the Bielschowski's assay revealed darkened and uneven neurofibrils staining in the hippocampus. The immunohistochemistry results showed a significant increase in Thr(231) phosphorylation of Tau protein in OA group relative to the control group (P<0.01). OA injection also markedly decreased PP2A activity (P<0.01). Western blot confirmed Thr(231) phosphorylation of Tau protein and it also detected phosphorylation of Ser(396) of Tau protein. The animals with Rb1 pretreatment displayed even staining of neurofibrils and normal pattern of fiber organization. Rb1 pretreatment also attenuated Thr(231) and Ser(396) hyperphosphorylations of Tau protein, and restored PP2A activity compared to the OA group (P<0.01). These results indicate that OA-induced hyperphosphorylation of Tau protein in rat hippocampal neurons can be attenuated by the pretreatment of ginsenoside Rb1. These data also implicate that Rb1 has potential neuroprotective effects on Tau-related neuropathology.
