Objective To identify the key factors triggering medical disputes induced by differences in cognition between doctors and patients in order to control the occurrence and development of medical disputes. Methods From 2002 to 2006,the outpatients,inpatients and medical staff of 3 hospitals in Shanghai(class 3 first level general hospital,n=2;class 3 first level special hospital,n=1) were investigated,and random sampling method was employed for the research analysis. Results There were significant differences between doctors and patients in cognition of influential factors triggering medical disputes such as health law,medical services,rights and obligations. Conclusion The differences in cognition between doctors and patients are important causes for medical disputes,and effective prevention and intervention measures must be taken.

Objective To evaluate the efficacy of thoracic cavity perfusion with cisplatin combined with mannan peptide in nasopharyngeal carcinoma patients with malignant pleural effusion.Methods 47 cases of nasopharyngeal carcinoma patients with malignant pleural effusion with a median age of 50 years old (41-70 years old) were enrolled.Pleural effusion occurred at 38.5 months on average after diagnosis,unilateral effusion was seen in 45 patients (95.7 ％),bilateral effusion was seen in 2 patients (4.2 ％).Cisplatin combined with mannan peptide was administered through pleural puncture by PICC center vein pipe after drainage.Data of survival complications and response to the treatment were reviewed.Results 17 patients (36.1％) had a complete remission (CR),21 patients (44.6 ％) had partial remission (PR),and the total remission rate (CR+ PR) was 80.9 ％.The median survival time was 10.5 months.Patients with pleural fluid pH ≥ 7.2,glucose ≥ 60 mg/L,and lactic dehydrogenase (LDH) ＜ 600 U/L showed association with good efficacy,the efficacy rates were 85.0 ％ (34/40),86.5 ％ (32/37),89.5 ％ (34/38),the median survival time were 11.5,12.0,12.5 months.Pleural fluid pH ＜ 7.2,glucose ＜ 60 mg/L,and LDH ≥ 600 U/L showed association with poor efficacy,the efficacy rates were 42.8 ％ (3/7),50.0 ％ (5/10),44.4 ％ (4/9),the median survival time were 6.5,6.5,6.0 months (P ＜ 0.05).The curative effect of the patients with bone metastasis and (or) pulmonary metastasis without liver metastasis was more similar with that of the patients with liver metastases [(47.0 ％ (16/34) vs 57.1％ (4/7),x2 =0.01,P =0.29].But median survival time had significant difference (11.0 vs 6.0 months,P =0.02).The Cox multi-factor analysis confirmed that the LDH value of effusion was an independent factor as prognosis evaluation.Major side effects of the treatment included fever,chest pain,nausea and vomiting.Conclusion Thoracic cavity perfusion using cisplatin combined with mannan peptide is effective in the treatment of malignant pleural effusion in nasopharyngeal carcinoma patients with pleural effusion,with relatively low toxicity.LDH value is a predictive factor for survival.The patients with liver metastases appeare poor median survival time.

A total of 1342 individuals underwent physical examinations according to the criteria of metabolic syndrome of International Diabetes Federation (IDF) in 2005.And 314 patients with metabolic disorders were screened for diabetes by standard meal and methods oral glucose tolerance test (OGTT).Newly diagnosed diabetics was 12 (4.1％ ) vs.17 (5.8％) respectively.No significant difference existed between two methods (P =0.332).Kendall's (τ)b =0.313,Kendall's (τ)c =0.208 and Gamma coefficient =0.580 (P =0.000).The mixed meal method was correlated with OGTT,Kappa =0.258 (P =0.000) and two methods were consistent.Diabetic screening should be stressed in the subjects with metabolic abnormalities.And the detecting efficiency of postprandial plasma glucose is similar to OGTT.

Objective To investigate the effect of natural killer (NK) cells treated by serum of severe preeclampsia patient on the function of endothelial cells.Methods Fifteen patients with severe preeclampsia and 15 normal pregnant women from the Obstetrics department,Shengjing Hospital,China Medical University were admitted into this case-control study from January 1,2006 to December 31,2008.NK cells from healthy non-pregnant woman were incubated with 20% serum from severe preeclampsia patients or normal pregnant women for 20 hours.Then,human umbilical vein endothelial cells ( HUVEC) and serum-treated NK cells were co-incubated for 24 hours.Apoptosis of HUVEC was checked by flow cytometry and electronic microscope.Endothelin-1 (ET-1) levels in the supernatants of HUVEC and NK cells were examined by radioimmunologic method.Results In severe preeclampsia group,the percentage of early apoptosis cell (Annexin V-FITC+ /PI+ ) was (23.81±4.79)%,that of late apoptosis cell (AnnexinV-FITC+/PI+ ) was (3.29±1.04) %,while those were (16.59±5.13)% and (2.24±0.72)% respectively in normal pregnant group (P＜0.01).There was no significant difference in dead cells (Annexin V-FITC- /PI+ ).Under electronic microscope,typical morphologic changes of apoptosis were shown in severe preeclampsia group.Level of ET-1 in

Totally 1136 individuals aged over 40 underwent health check up in March to May 2009. Fasting blood glucose, 2-h post-challenge blood glucose, glycated hemoglobin A1c ( HbA1c), total cholesterol, triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and serum uric acid were measured. The diagnosis of metabolic syndrome was based on the International Diabetes Federation Criteria. The results shows that total body fat, region body fat indices, blood pressure, blood glucose and serum uric acid levels increased with the age ( P < 0.01) . The prevalence rate of metabolic syndrome in this group of individuals were 15. 1% (171/1136) , and increased with age (P<0.01). The most common combination of metabolic syndrome was central obesity-hypertension-dyslipidemia (40. 9% , 70/171). Unconditional logistic regression revealed that waist-hip-ratio, body mass index and uric acid were the risk factors for metabolic syndrome.

Objective To summarize the clinical and pathological characteristics of primary gallbladder carcinoma, analyze factors such as surgical procedures, tumor stages that associated with prognosis, and standardize the diagnosis and treatment strategy for primary gallbladder carcinoma.Methods From January 1986 to October 2009, 197 patients of primary gallbladder carcinoma were treated in Peking Union Medical College Hospital (PUMCH). A retrospective study was performed basing on clinical data of these patients, statistical analysis carried out using SPSS version 13.0, Kaplan-Meier estimate employed for the survival analysis and Log-rank test for the group comparisons. Results One hundred and ninety-seven patients were enrolled (73 male and 124 female) with the mean age of 64.4±1.1years. Abdominal pain (77.3%) , obstructive jaundice (33.6%) and fever (19.5%) were the main symptoms of primary gallbladder carcinoma, with accompanying cholecystolithiasis in 99 cases. B-mode ultrasonic examination and CT scan were important for preoperative diagnosis. Nevin stages and surgical modalities were independent prognosis factors. For stage Ⅰ and Ⅱ patients the survival terms were not different between those receiving radical cholecystectomy and simple cholecystectomy. However, for stage Ⅲ, Ⅳ and Ⅴ patients the survival terms were of statistically different between those in radical cholecystectomy group and simple cholecystectomy group. Conclusions For stage Ⅰ and Ⅱ patients, simple cholecystectomy is a good surgical procedure. For those at more advanced stages, radical cholecystectomy is the choice of therapy, while simple cholecystectomy also improves the prognosis compared with laparotomy only.

Objective To explore risk factors for type 2 diabetes mellitus complicated with gallstone disease. Methods The clinical data of 429 type 2 diabetes mellitus patients complicated with gallstone disease (case group) and 2145 type 2 diabetes mellitus patients without gallstone disease (control group) were collected from the Health Center of Peking Union Medical College Hospital from January 2007 to May 2010. According to sure (SBP), diastolic blood pressnre (DBP), fasting blood glucose (FBG), total cholesterol (TC), Triglyceride (TG), high-density lipoprotein cholesterol (HDL-CH), low-density lipoprotein cholesterol (LDL-CH) and body mass index (BMI) were statistically analyzed by fourfold table chi-square test or conditional Logistic regression.Results Univariate analysis showed that there was a significant difference in the levels of SBP, FBG, TC, HDL-CH and BMI between the case group and the control group (x2 =20.323, 4.365, 4.028, 7.049, 7.319, P＜0.05). Multivariate analysis confirmed that SBP, TC, HDL-CH and BMI were risk factors for gallstone disease in patients with type 2 diabetes mellitus (x2 = 18. 047, 6. 905, 12. 884, 7. 557, P ＜ 0. 05). Conclusion Increased SBP, TC and BMI and decreased HDL-CH may be the risk factors for type 2 diabetes mellitus complicated with gallstone disease.
