ObjectiveTo review surgical management of the complications caused by iatrogenic endoscopic sphincterotomy(EST).MethodsEleven patients with complications of EST were surgically treated, including 4 patients with hemorrhage, 3 patients with perforation, 3 patients with perforation plus hemorrhage, and one patient with perforation plus severe pancreatitis. ResultsTwo patients with perforation plus hemorrhage and the patient with perforation plus severe pancreatitis died, other patients survived.ConclusionEarly diagnosis and surgical intervention was very important to lower the mortality. For patients suffering from perforation and hemorrhage or pancreatitis, it′s very important to make an unobstructed peritoneal drainage as well as other maneuvers.

Objective To validate the analytical performance of four LP(a)reagents with Immunoturbidimetry method used on the automatic biochemistry analyzer for preliminary clinical application.Methods The performance of four LP(a)reagents (labeled as A,B,C,D)with method from RANDOX,Zhejiang Kuake Co.,Beijing Leadman Co.and Beijing Jiuqiang Co.on Olympus AU5800 automatic biochemistry analyzer were assessed.The precision,linearity range,accuracy,disturbance (vita-min C,bilirubin,hemoglobin,TG)were assessed.Results The within-run CVs of the four reagents (A,B,C and D)were 0.64%~1.18%,3.59%~4.75%,1.33%~3.05% and 1.43%~2.01% respectively.The between-run CVs in A,B,C and D were 1.04%~1.7%,3.81%~4.93%,2.16%~4.76% and 2.33%~3.21% respectively,lower than the stated.The lin-earity range was 82~923 mg/L (r2 =0.997),130~935 mg/L (r 2 =0.996 4),120~1025 mg/L (r 2 =0.992 1)and 117~943 mg/L (r2 =0.999 5)in the four reagents,which demonstrated a sound linear correlation.For interference tests,no re-markable interferences (<±10%)of reagent A and reagent D were detected when Vitamin C≤10 mg/dl,hemoglobin≤200 mg/dl,bilirubin≤40 mg/dl and TG≤500 mg/dl.Interference of reagent B was found when VC≥5 mg/dl,TG≥250 mg/dl and when TG≥250 mg/dl reagent C was interfered significantly.The four LP(a)reagents were used to detect the lipid con-trol,and the deviations of the target value were - 8.07%,1.34%,- 8.05% and 7.38% respectively.Conclusion When used in automatic biochemical analyzer,the four LP(a)reagents showed high precision.The four reagents are all able to meet clinical test requirements,nevertheless,anti-interference capability were different.

More than 85% of all cancers express telomeras e activity. Human telome rase has been proposed as a novel and potentially highly selective target for ca ncer therapy. Inducers of differentiation are involved in regulation of telomera se activity. In the present review, the effects of retinoids, vitamin D3 compo unds, tea catechins and matrine on telomerase activity in malignant cells were r eviewed.

Objective To assess the quality of life(QOL) in rheumatoid arthritis(RA) patients treated with 12weeks of aerobic exercise(AE) plus medication(methotrexate, MTX, and NSAIDs). Methods The research design was a randomized controlled trial. The patients in AE group received AE plus MTX and NSAIDs, and the patients in the control group received drug therapy only. Results One hundred and twenty six patients completed the trial, AE patients with improvement of 12%～28% from the baseline were better than medicine treated patients in the physical, social, emotional function, self recognized health status and total QOL. Conclusion AE is effective for the patients with RA in the improvement of QOL.

To investigate the chemical constituents of the roots of Aconitum taipaicum, silica gel column chromatography was used for the isolation and purification of compounds. A new norditerpenoid alkaloid, isodelelatine (1), along with five known alkaloids, atisine (2), delfissinol (3), liangshanine(4), hypaconitine (5) and delelatine (6) were isolated and identified. The structure of the new compound was elucidated on the basis of spectral data.

Objective:To determine the effects of ginsenoside Rg1 on the expression levels of bone gla protein(BGP) and cytokine interleukin-6(IL-6) in the periodontium of experimental periodontitis rats.Methods:One hundred 160-200 g Wistar rats were randomly divied into ten groups.Group A used as control were killed at the beginning of the experiment.Group B-J were experimental periodontitis models.Group B-E received the therapy of ginsenoside Rg1 were killed at 1st,2nd,3rd and 4th weeks.Group F-J received no treatment as periodontitis control were killed at 0,1st,2nd,3rd and 4th weeks.The expression levels of BGP and IL-6 in the periodontium were measured by immunohistochemistry.Results:The expression levels of BGP in the group F were significantly lower than that in the group A,the expression levels of IL-6 in the group F were much higher than that in the group A(P
