Objective To research the relationship between binocular acuity and monocular acuity,and their effect on the evaluation of visual impairment and disability. Methods 1006 patients, aged between 18 and 60 years, are measured monocular and binocular acuities after the best lens correction. Results Binocular vision is higher than, equal to and less than monocular vision, three accounted for 27.14%, 70.78% and 70.78% respectively. Interocular difference has certain correlation with binocular interactions (χ2=54.939,P<0.05,r=0.228). Thirty-three patients have same binocular acuity but different monocular acuity. Conclusion Binocular acuity associated with the monocular acuity and the better eye vision plays a special role in visual disability evaluation.

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.

Objective To investigate the risk factors of gallbladder carcinoma,so as to provide theoretical base for the prevention of gallbladder carcinoma.Methods The clinical data of 153 patients with gallbladder carcinoma (gallbladder carcinoma group) who were admitted to the Peking Union Medical College Hospital from January 2000 to December 2010 were retrospectively analyzed. A total of 300 patients with cholecystolithiasis (cholecystolithiasis group) and 300 patients without gallbladder carcinoma or cholecystolithiasis (control group)were collected and matched at the ratio of 1∶2 to conduct the controlled study.Data were statistically analyzed by the Chi-square test and conditional Logistric regression.Results Univariate analysis showed significant difference in age,history of cholecystolithiasis,postmenopausal age,accumulated menstrual period,giving birth or not and number of birth between gallbladder carcinoma group and control group ( x2 =58.22,180.14,9.59,24.30,18.66,15.17,P <0.05).Age,history of cholecystolithiasis,accumulated menstrual period and number of birth were the independent risk factors of gallbladder carcinoma (x2 =55.76,180.95,24.30,8.54,P < 0.05).The risk of having gallbladder carcinoma in patients who had a history of cholecystolithiasis was 34 times higher than those who did not have the history of cholecystolithiasis (OR =34.22).Late postmenopausal age (51 -55 years old),longer accumulated menstrual period ( ≥30 years),and the number of birth ( 3 times) were associated with higher risk of gallbladder carcinoma (OR =3.96,9.68,3.51 ). Age,course of cholecystolithiasis and accumulated menstrual period and number of birth were the risk factors of gallbladder carcinoma when comparing patients who have history of cholecystolithiasis in the gallbladder carcinoma group with those in the cholecystolithiasis group (x2 =70.66,16.66,11.59,4.69,P < 0.05 ).Age,course of cholecystolithiasis and accumulated menstrual period were the independent risk factors of gallbladder carcinoma ( x2 =64.29,8.82,5.58,P < 0.05).The risk of gallbladder carcinoma increased as the increase of age and course of cholecystolithiasis. The accumulated menstrual period ≥ 30 years was also a risk factor of gallbladder carcinoma. Conclusions Age,history of cholecystolithiasis,course of cholecystolithiasis,accumulated menstrual period and number of birth may be the risk factors of gallbladder carcinoma.For patients with age above 60 years and course of cholecystolithiasis above 3 years,cholecystectomy should be conducted to reduce the incidence of gallbladder carcinoma,and great importance should be attached to female patients with indications mentioned above.

Objective To analyze the clinicopathological features of gallbladder adenosquamous carcinoma.Methods The clinical data of 8 patients with gallbladder adenosquamous carcinoma who were admitted to the Peking Union Medical College Hospital from January 2000 to December 2010 were retrospectively analyzed.The clinicopathological features,diagnosis and treatment strategies were summarized.The survival curve was drawn by Kaplan-Meier method,and the survival of the patients was analyzed by Log-rank test. Results The clinical manifestation of the 8 patients was non-specific,and all the patients were misdiagnosed as with primary gallbladder cancer complicated with cholecystolithiasis or chronic cholecystitis.The levels of carcinoembryonic antigen and γ-glutamyl transferase of 3 patients were higher than the normal,the level of alkaline phosphatase of 2 patients was higher than the normal,the level of aspartate transaminase of 1 patient was higher than the normal,the level of CA242 of 3 patients was higher than the normal and the level of CA19-9 of 4 patients was higher than the normal.The levels of aspartate transaminase,total bilirubin and direct bilirubin were in the normal range. Different surgical approaches were selected according to different tumor positions.The mean diameter of the tumor was (5 ±3)cm. Lymph node metastasis was detected at the hepatic hilar,hepatoduodenal ligament and area behind pancreatic head. Postoperative pathological examination confirmed that all the patients were with gallbladder adenosquamous carcinoma. All patients were followed up till April 2011. Two patients survived with no discomfort,and the survival time was 2-3 months.Six patients died of tumor recurrence or metastasis,and their median survival time was 8 months (range,4-13 months). Conclusions The clinical manifestation of gallbladder adenosquamous carcinoma is non-specific, and definite diagnosis depends on the results of postoperative pathological examination.Surgical treatment is the only effective method in improving the prognosis of patients with gallbladder adenosquamous carcinoma,and the prognosis of patients is poor.
