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.

Objective To explore skeletal‐related events (SREs) clinical factors and analysis prognosis factors on patients with non‐small cell lung cancer(NSCLC) with bone metastases .Methods We collected clinical data of pathology confirmed 383 patients with non‐small cell lung cancer between April 2007 and January 2007 in the third affiliated hospital of the third military medical uni‐versity .It was used to screening for Emission Computed Tomography (ECT ) for bone metastases .And then it was need to con‐firmed for CT ,MRI or PET‐CT or pathology .Statistics in patients between clinical features and the SREs prediction factor with Univariate and Multivariate .And Kaplan‐Meier method analysis of survival in the non‐small cell lung cancer patients with bone me‐tastases .Results Out of 383 patients with bone metastases ,178 patients with SREs .The incidence was 46 .5% .Univariate analysis showed that women ,adenocarcinoma ,never smoking history ,single bone metastases ,bisphosphonate therapy ,targeted therapy in patients with bone metastases are less likely to have SREs ,it was considered statistically significant (P<0 .05) .Multivariate analy‐sis showed multiple bone metastases and no bisphosphonate therapy is independent risk factors for SREs .Median survival time was 14 .5 months in non‐small cell lung cancer patients with bone metastases ,1 year survival rate was 46 .5% ,2 years survival rate was 15 .9% .The survival analysis shows that more bisphosphonate treatment and bisphosphonate with EGFR‐TKI therapy on the prog‐nosis of patients with statistically significance (P<0 .05) .Conclusion It was likely to occur SREs in NSCLC patients with bone metastases .No bisphosphonate and multiple bone metastases are independent risk factors for SREs .Bisphosphonate treatment may prevent or reduce occur SREs for NSCLC patients with bone metastases ,and it may prolong survival ,it speculated that bisphospho‐nate may have resistant NSCLC cell activity .

Objective To discuss the clinical effect of transurethral cystitis glandularis electrocision combined with treating the diseases under bladder outlet in female.Methods One hundred and two female cases of cystitis glandularis who received transurethral electrical resection of the bladder mucosa combined with treating the diseases under bladder outlet were selected as experimental group,and another 78 female cases were selected as control group,who only received transurethral electrical resection of the bladder mucosa.The visual analogue score (VAS) was observed before and after a 12-week treatment,and the efficacy was evaluated by analysis of non parameter RIDIT.Results The operation time in experimental group and control group were 15-40 (26 ± 13) min and 8-19 (13 ± 5) min,respectively,and there was significant difference between two groups (P ＜ 0.05).Two groups cases urinated smoothly after the removal of catheter,without the occurrences of urinary fistula and incontinence.During the 12-weeks of follow-up,44 cases were cured,31 cases improved,15 cases were effective and 12 cases unimproved in experimental group; 26 cases were cured,21 cases improved,16 cases were effective and 15 cases unimproved in control group.There was significant difference between two groups (R =0.576,95％ CI0.519-0.633,P＜ 0.05).Conclusion Although the operation time is lengthened by transurethral cystitis glandularis electrocision combined with treating the diseases under bladder outlet in female,this method obviously improves curative effect.

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.

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.
