ObjectiveTo compare the efficacy and health economics between open choledocholithotomy and endoscopic sphincterotomy (EST) these two operations on patients with choledocholithiasis. Methods177 patients (aged 20-75 yrs, with simple choledocholithiasis on medical imaging,who had not been treated with either biliary tract surgery or EST, and had no severe complications)were treated electively at the Beijing Friendly Hospital and Beijing Jishuitan Hospital from 2002 to 2009. These patients were divided into two groups according to the treatment they received: open operation (n=62), or EST (n=115). There was no significant difference in sex, age, ASA class,symptoms before operation, and complications before operation between the 2 groups. The following data were compared: operation time, blood loss, size and number of stone, duration of postoperative ileus, duration of abdominal pain, incidence of postoperative complications, duration of hospitalization, cost of hospitalization and operation, and incidence of residual stones. ResultsFor the open operation group, the operation time was 50-300 min (M=110), the blood loss was 10-300 ml (M=60), the duration of post-operative ileus was 24-96 h(M=48), the duration of abdominal pain was 0-96 h(M=48), the duration of hospitalization was 8-70 d(M=21), the duration of hyperamylasemia after operation was 8.1％ and the cost for operation was 546-2498 yuan (M=1503. 2). For the EST group, the operation time was 10-120 min (M=25), the blood loss was 2-40 ml (M=10),the duration of post-operative ileus was 1-48 h (M=3), the duration of abdominal pain was 0-144 h (M-0), the period of hospitalization was 5-56 d (M=17), the duration of hyperamylasemia after operation was 40％ and the cost for operation was 2028-5728 yuan (M=2028). There were significant differences in every aspect between these 2 groups of patients. Conclusions EST has a significantly shorter operation time, less blood loss, shorter duration of postoperative ileus, shorter duration of abdominal pain, shorter duration of hospitalization. However, EST had a significantly higher incidence of hyperamylasemia after operation and the cost was higher than open operation.

[Objective]To recommend the detailed operative skill of lower cervical transpedicle screw and peri-operative experience.[Method]From July 2004 to April 2006,based on anatomical research of cadaver,15 cases involved lower cervical had been treated by transpedicle screws and plate or rod,which assisted in fluoroscopic moniter.Lateral mass needed be revealed completely,thus basilar part of superior articular process could be recognized.The central point of screw inserted were laid on the surface of lateral mass: 5mm inner to the outside border of lateral mass;3mm below to the inferior of superior articular process.Ball-like burr was used to de-cortical.Made a pathway with 2 mm hand-drill paralleled with the upper end-plate cartilage of the vertebra and maintain abduction angle about 40?～45? with middle line of the vertebra,self-designed pedicle probe was used to ensure safety tunnel of cancellated bone.3.5 mm cortical screws were adoption and thread was not recommend.[Result]Eightysix lower cervical pedicle screws had been inserted successfully in C3～7 vertebra,exclude a failed C4 screw.Average screws length was(26 + 1.6)mm and abduction angle based on postoperative CT scan was 37.9??5.4?.Abundant bleeding was occurred while built the pedicel pathway in 2 screws,and there were 6 screws showed perforation of the pedical wall refer to postoperative CT scan. No evidence indicated the complication about injury of vessel or nerve structure.[Conclusion] The technique of lower cervical transpedicle screw are relatively safet.Successful screw insertion depends on subtile sense of operation doctor's hand.

Objective To investigate the polymorphism of the vitamin D receptor(VDR)gene in relation to primary hyperparathyroidism(PHPT). Method Polymerase chain reaction and restriction analysis were used to determine VDR genotypes in 30 patients with PHPT and in normal subjects.ResultsThe frequency distribution of VDR genotypes in PHPT patients was 0 in BB,1(3.3%) in Bb, 29(96.7%) in bb; and in normal persons was 2(3.3%) in BB, 11(18.4%) in Bb, and 47(78.3%) in bb. There was a significant difference between PHPT patients and normal persons in distribution of BB, Bb, bb genotypes (P≤0.05).ConclusionsThere is some distribution alterations of VDR gene polymorphism in PHPT patients.

ObjectiveTo explore the biological features of colorectal adenoma with chicken-skin mucosa ( CSM ) and its clinical significance.MethodsExpression of cell proliferation markers ( Ki-67 and COX-2) and apoptosis-related factors ( survivin and caspase-3) in normal colorectal mucosa,colorectal adenoma without CSM,colorectal adenoma with CSM and colorectal adenocarcinoma were detected by immunohistochemistry SP method and enzyme-linked immunosorbent assay (ELISA).ResultsImmunohistochemical results revealed a decreased trend in expressions of Ki-67 and COX-2 from colorectal adenocarcinoma through colorectal adenoma with and without CSM to normal colorectal mucosa,while the expressions of survivin and caspase-3 showed an increased trend.By ELISA,the expressions of Ki-67,COX-2,surviving and caspase-3 showed no significant difference (P ＞ 0.05 ) between colorectal adenoma with CSM and coloreetal adenocarcima,while these variables were significantly different (P ＜ 0.05) between coloreetal adenoma with and without CSM,so as well between normal colorectal mucosa and other 3 groups.ConclusionThe biological characteristics of colorectal adenoma with CSM are different from those without,showing an activated cell proliferation and inhibited cell apoptosis with increased carcinogenesis risk.

Objective To investigate the effect of delighted thinking on improving negative emotion of depression patients. Methods 100 depression patients were randomly divided into the observation group and the control group with 50 in each according to admission sequence. Both groups was executed antidepressionant drugs treatment and routine psychiatric care simultaneously. The observation group was given delighted thinking training on the basis of above treatment. The emotional recovery of two groups was observed. Results There was significant difference on facial expression, communication and limbs language after executing delighted thinking training in the observation group. And there was significant difference on scores of Hamilton depression rating scale (HAMD) at discharge. Scores of Nurses' Observation Scale during early, middle and late stage of delighted thinking training greatly improved compared with those before training. Conclusions Delighted thinking contributes to throw off negative thinking pattern of self-denial, stimulate positive passion threshold, improve depressed mood and raise treatment effect for depression patients.

Objective To summarize the experience on diagnosis and treatment of primary hyperparathyroidism(PHPT).Methods Clinical data of 91 PHPT patients treated in Beijing Jishuitan Hospital from November 1992 to December 2008 were analyzed retrospectively.Results Among 91 PHPT cases,88 were diagnosed as parathyroid adenoma(96.7%),3 were diagnosed as parathyroid carcinoma (3.3%).Serum calcium and PTH levels increased in all cases.Main clinical manifestations were osteodynia and kidney stones.The accuracy rate of preoperative B-ultrasound.CT and ECT~(99m)Tc-MIBI on location was 83.5%(76/91),60.9%(14/23)and 98.6%(69/70)respectively.Parathyroidectomy was performed in all but one cases,in which parathyroid carcinoma was managed by ipsilateral hemithyroidectomy and modified neck dissection.The cure rate of primary operation was 97.8%(89/91).Ninety cases were followed-up from 8 months to 14 years postoperatively,87 cases with parathyroid adenoma achieved complete remission,2 with parathyroid carcinoma suffered from tumor recurrence and 1 died.Conclusion Patients with chronic bone diseases,repeatedly recurrent nephrolithiasis,peptic ulcer disease should be a suspect of PHPT.The routine examinations of serum calcium and phosphorus are to be conducted.UItrasonography and ECT~(99m)Tc-MIBI should be considered as the methods of first choice for preoperative localization.
