AlM:To compare the results of lOL Master, contact and immersion A-scan ultrasound measurements for anterior chamber depth ( ACD ) , and evaluate the difference and consistency.METHODS:Fifty-eight cases (98 eyes) with age-related cataract during July to October in 2013 did the A-scan ultrasound with contact and immersion measurements and lOL Master to get the results of ACD. Difference in measurements between methods was assessed using the variance analysisi. Consistency was assessed using Bland-Altman.RESULTS:The ACD measured by lOL Master was 2. 31~3. 90mm, the mean was 3. 03 ± 0. 38mm. The ACD measured by contact A- scan ultrasound was 1. 51 ~4. 06mm, the mean was 2. 88 ± 0. 56mm. The ACD measured by immersion A-scan ultrasound was 1. 99 ~4. 17mm, the mean was 3. 17±0. 38mm. The results of lOL Master and contact A - scan ultrasound had statistical differences (P=0. 022<0. 05). The results of lOL Master and immersion A - scan ultrasound had statistical differences (P=0. 031<0. 05). The results of contact A-scan ultrasound and immersion A-scan ultrasound had statistical differences (P=0. 000<0. 05). The consistency between three methods was poor. CONCLUSlON: The rank of ACD of patients with cataract is immersion A-scan ultrasound, lOL Master and contact A-scan ultrasound. The consistency is poor, and the three methods can’t be interchanged clinically.

Prostate cancer is one of the most common malignant tumors in the male urinary system as well as the second leading cause of cancer death in men. Prostate specific antigen (PSA) screening is the main method for the early diagnosis of prostate cancer, but has a low specificity for its detection. In recent years, a variety of tumor markers with high sensitivity and specificity have been found. This review focuses on some of the more promising tumor biomarkers such as prostate cancer antigen 3, early prostate cancer antigen, prostate-specific membrane antigen, alpha-methylacyl-CoA racemase, and vascular endothelial growth factor.

Objective To study the effects of staphylococcal enterotoxin B(SEB) on the proliferation of tumor infiltrating lymphocytes(TILs) from rectum adenocacinoma.Methods The TILs from patients with rectum adenocacinoma were stimulated with SEB and interleukin 2(IL-2) respectively,and then the proliferation of TILs,the secretion of IL-2 and tumor necrosis factor-?(TNF-?) were determined.Results SEB presented profound stimulating effect on the TILs from rectum adenocarcinoma both the proliferation of TILs and the secretion of cytokines.Compared with the IL-2,SEB stimulated TILs more quickly,and SEB acted more effectively in the early stage but weakly in the late stage.Conclution SEB was an effective TIL stimulator.

AlM:To evaluate the value of color Doppler ultrasound in the diagnosis of traumatic retinal detachment.
METHODS: All 50 cases ( 56 eyes ) of suspicious traumatic retinal detachment from January to June in 2013 were enrolled in this study. All first received the two-dimensional ultrasound, then the color Doppler ultrasound, finally, these results were compared with the results of surgery.
RESULTS: All 56 eyes were observed intravitreal abnormal spots by the two-dimensional ultrasound, and 39 eyes were observed color blood signal by the color Doppler ultrasound. Forty eyes were approved retinal detachment by surgery.
CONCLUSlON: lt is better to display the intravitreal abnormal spots and color blood signal by the color Doppler ultrasound than by the two - dimensional ultrasound, so there is important clinical significance of the color Doppler ultrasound in the diagnosis of traumatic retinal detachment.

Irritable bowel syndrome(IBS) is a quite common disease,and it is a functional enteropathy that characterized by abdomen discomfort or pain,diarrhea,constipation or the mix of both.At present the clinical diagnosis refers to the Roman Ⅱ standard,but it is easy to create leaks examines.In 2006,the new Roman Ⅲ standard let clinician have a more objective basis regarding diagnosis of children with IBS.Its treatment is a complex therapy based on the symptom and serious degree of the symptom.The author will introduce children with IBS with emphasis on the diagnosis and treatment progress.

Objective:To compare the bone dimensional changes following tooth extraction alone with extraction plus ridge preservation ( using deproteinized boving bone mineral Bio-Oss? and bioresorbable collagen mambrane Bio-Gide?) in periodontal compromised extraction sockets .Methods: Eighteen molars of sixteen subjects requiring tooth extraction because of periodontal destruction were enrolled in this study .The subjects were assigned to the control group ( extraction alone , EXT) or to the test group ( ridge-preservation procedure with Bio-Oss? and Bio-Gide?, RP) .Parallel periapical X-rays and cone-beam computed tomography ( CBCT ) scans were taken immediately after tooth extraction alone or plus ridge-preservation ( baseline ) and 6 months later .The changes of horizontal ridge width and vertical ridge height were assessed .Results:At the central buccal aspect , the ridge height increased 2 .9 mm in RP group, and reduced 1.0 mm in EXT group.At the distal buccal aspect , the ridge height increased 1.45 mm in RP group, and reduced 1.45 mm in EXT group.The differences between the groups reached statistical significance (P<0.05).The mean ridge width increased at the 1 mm below the crest (the horizontal ridge width was measured with grafting material at three levels at 1 mm below the most coronal aspect of the crest,HW1), which amounted to 3.40 to 5.80 mm in RP group, and 1.45 to 2.90 mm in EXT group.The mean ridge increased at the 4 mm below the crest ( the horizontal ridge width was measured with grafting material at three levels at 4 mm below the most coronal aspect of the crest ,HW4 ) , which amounted to 0.40 to 3.50 mm in RP group, and reduced 0.10 to increased 0.15 mm in EXT group.The test group and the control group were not significantly different (P>0.05).Conclusion:The ridge-preservation approach using Bio-Oss? in combination with Bio-Gide? can significantly increase vertical ridge height and horizontal ridge width after tooth extraction compared with extraction alone in periodontal compromised molars .
