To investigate the effect of calcium concentration in dialysate on the QT interval (QT) and QT interval dispersion (QTd) during hemodialysis(HD) in patients with end stage renal disease (ESRD), Ca 2+ concentrations of 1 25mmol/L (dCa 2+ 1 25), 1 5mmol/L (dCa 2+ 1 5) and 1 75mmol/L (dCa 2+ 1 75) in dialysate were given to 15 ESRD patients for five times. The QT and QTd were measured before and after the five HD sessions. The results showed: With the dCa 2+ 1 25 HD, serum Ca 2+ and plasma calcium were decreased (1 22?0 08 vs 1 17?0 07 mmol/L and 2 43?0 34 vs 2 28?0 16mmol/L, P 0 05). The changes in the QT correlated inversely with the changes in serum Ca 2+ and plasma calcium ( P

Objective] To observe the clinical effect of Yiyuan Shengjing Decoction on similar climacteric syndrome of breast cancer after treated with tamoxifen. [Method] Choose 60 cases of breast cancer, randomly divide them into control group 30 cases and treatment group 30 cases, the control one were treated with tamoxifen and oryzanol, the treatment one, with tamoxifen and Yiyuan Shengjing Decoction. After 4w, evaluate the efficacy, compare their clinical symptoms score, hormone levels and endometrium thickness, and calculate the clinical relieving rate. [Result] After treatment, both groups clinical symptoms were relieved more than before treatment, with difference of statistical meaning; comparing on clinical symptoms scores, the treatment was much less than control one, with statistical meaning; on clinical relieving rates, the treatment group reached 83.33%, while 26.67% for control one, both had difference of statistical meaning. The comparison of reproductive hormone levels and endometrium thickness, the difference had no statistical meaning. [Conclusion] Yiyuan Shengjing Decoction treating breast cancer similar climacteric syndrome after treated with tamoxifen had marked cure effect, without influencing reproductive hormone level and endometrium thickness.

Neovascular glaucoma is a rare and severe complication of hypoperfusion retinopathy.The appearance of hypoperfu- sion retinopathy complicating neovascular glaucoma in ophthalmolscopy and fundus fluorescein angiography shows a special feature. Neovascular glaucoma occurs when new fibrovascular tissues proliferate onto the chamber angle and obstruct the trabecular meshwork. The stenosis or occlusion of internal carotid artery is the most common reason of hypoperfusion retinopathy in elder people.Early recog- nition and treatment of patients with carotid occlusive diseases may prevent more serious complications.

Objective To analyze the safety and clinical efficacy of three types stents of transjugular intrahepatic portosystemic shunt (TIPS) in treatment of cirrhosis with portal hypertension.Methods Totally 1 086 patients with cirrhotic portal hypertension underwent TIPS for the first time.All patients were divided into bare stent group (group A),covered stent-group (group B) and combined stents group (group C).The rates of symptom improvement,shunt insufficiency,re bleeding,survival and major complications in 2 years after TIPS were analyzed and compared.Results Totally 1 690 stents were placed in 1 086 patients.The overall technical success rate was 100％;2.53％ (10/396) emergency patients dead due to uncontrolled gastrointestinal bleeding,and 2.78％ (11/396) emergency patients,0.84％ (5/593) bleeding stopped patients dead with acute liver funtional failure.In 2-year following-up,the overall survival rate of group A,group B,group C were 83.78％ (186/222),88.36％ (281/318),96.34％ (526/546),and the difference was statistical significant (x2=4.15,P=0.04).The shunt insufficiency rates of group A,group B,group C were 39.64％ (88/222),22.33％ (71/ 318),11.17％ (61/546),and the difference was statistical significant (x2 =4.15,P=0.04),The rates of rebleeding of group A,group B,group C were 31.53％ (70/222),16.89％ (54/318),7.14％ (39/546),and the difference was statis tical significant (x2 =9.91,P=0.01).The rates of hepatic encephalopathy of group A,group B,group C were 21.62％ (48/222),22.96％ (73/318),19.23％ (105/546),and the difference had no statistical significant (x2 =1.00,P=0.06).Conclusion TIPS is an effective way to relieve portal hypertension and complications in patients with cirrhosis.The safety and clinical efficacy can be improved by 8 mm shunt with double stent technique.

Objective To study the diagnostic value of double-balloon endoscopy (DBE) and capsule endoscopy (CE) for small intestinal bleeding. Methods Overall detection rates of small intestinal bleeding with DBE, CE and the whole alimentary tract barium meal were compared. Positive rates of bleeding detection with DBE and CE were compared within the same patients. Influence of CE on one-procedure rate of DBE was analyzed. Results In 105 cases of small intestine bleeding, DBE detected 24 cases of Crohn's disease, 15 adenocarcinoma, 12 chronic nonspecific inflammation, 10 small intestinal ulcer of unknown reason, 8 entero-mesenchymoma, 8 polypus, 6 vascular deformation hemorrhage, 5 ancylostomiasis, 5 Mechel's diverticula ( including multiple diverticula), 3 lymphoma and 9 of no evident abnormalities. The positive detection rate of DBE is 91.4% (96/105). Disease detection rates of CE and whole alimentary tract barium meal were 75.0% (30/40) and 33.3% (25/75), respectively. The one-procedure rate of DBE is 90% (36/40) based on CE results, but it was only 69. 2% (45/65) according to clinic features and the whole alimentary tract barium meal. Conclusion The main causes of small intestinal bleeding are benign ulcers (including Crohn's disease) and tumor, as well as chronic inflammation. Polyps, vascular deformation, parasitosis, Mechel's diverticulum and lymphoma are the secondary causes.DBE is superior to CE in diagnosis of small intestine bleeding, but CE can increase the one-procedure rate of DBE.

Objective To explore the preventive and therapeutic role of silencing type Ⅰ rat platelet-binding protein motifs depolymerization protein-like metalloproteinase 2(ADAMTS2)by siRNA on experimental liver fibrosis in vitro.By studying the mechanism of siRNA silencing of ADAMTS2,we also aim to evaluate the feasibility of ADAMTS2 as a target for anti-liver fibrosis therapy.Methods Three pairs of siRNAs targeting ADAMTS2 mRNA 2237,2597 and 690 targets were designed and synthesized by utilizing RNA design software.The most effective siRNA was chosen to transfect HSC-T6 cell line to test the tendency of hepatic stellate cell(HSC)activation and ex pression of ADAMTS2,COL1α1,COL(I),α-SMA,TGF-β1,MMP-2 and TIMP-3.These were quantified using real time-PCR,Western blotting,and MTT assays.Results Of the same dosage and time of injection,siRNA 2237 inhibited ADAMTS2 gene expression significantly more than other siRNAs.siRNA-ADAMTS2 2237 markedly inhibited ADAMTS2 gene and protein expression of HSCT6 with more than 80％ efficiency.Conversely,siRNA-ADAMTS2 2237 markedly reduced the gene and protein expressions of COL(I),α-SMA and TGF-β1 on HSC-T6 and inhibited the proliferation of HSC.Conclusions siRNA-ADAMTS2 2237 could effectively knockdown the gene and protein expression of ADAMTS2 in HSC-T6 cell lines.Silencing ADAMTS2 by siRNA significantly inhibited the activation,proliferation of HSC and the gene and protein expressions of COL(I),α SMA,and TGF-β1,and it may have a potential anti-fibrotic effect.ADAMTS2 might be an efficient target for anti-fibrotic therapy.
