Objective To discuss the ultrasound diagnosis on the apophysis lesions of the gallbladder. Methods A retrospective analysis was made in 51 cases of polypoid lesions of gallbladder ultrasound char-acteristics of cases, clinical symptoms and pathological types. Results There were 43 cases of benign le-sious (39 cases of cholesterol polyp, 3 cases of adenomyosis, 1 case of inflammatory polyps), 8 cases of tumor lesions (5 cases of adenomatous polyp, 3 cases of malignant tumors). Among those patients with out clinical symptoms (n = 32) were for cholesterol polyps (P < 0. 05) while in, with symptomatic patients (21 cases), 8 were complicated with stone, 4 with ulcerative disease. Three cases (100%) with adenomyosis and 4 cases (80%) with adenomatous polyposis shouwed symptoms (P < 0. 05). Patients with multiple pol-ypoid lesions (22 cases), were benign lesions, and 95.5% were pathologlicdly cholesterol polyp. Seven ca-ses of ultrasound diagnosis of gallbladder polyps were pathologically diagnosed having polyp diameter smaller than 0.3 cm. Ultrasound showed gallbladder wall thickening in 6 cases, 3 with adenomyosis (wall thickness 0. 5 - 1.8 cm), 3 with malignant lesions in gallbladder (wall thickness 0. 5 - 1.2 cm). Conclusions For those patients ultrasound showed asymptomatic or multiple polyps of the gallbladder, cholesterol polyps are the most common type of lesion. Ultrasound is not sensitive to polypoid lesions of the gallbladder with diame-ter less than 0. 3 cm. Those with limited ultrasonic gallbladder wall thickening (>0. 5 cm) should pay more attention to the possibility of having malignant tumors and adenomyosis.

This review summarizes the recent research progress of bismuth-based nanomaterials in tumor diagnosis, treatment and biosafety, which provides a theoretical basis for the design and exploitation of a new generation of bismuth-based nanomedicine systems.

Objective To analysis the cause of injury of traumatic optic neuropathy and explore the main factors affecting the prognosis of visual acuity. Methods We retrospectively collected clinical data of 104 cases (108) of traumat-ic optic neuropathy from January 2007 to December 2012 in the Renhe Hospital of Three Gorges University. We then ex-amined the cause of injury and analyzed risk factors for poor prognosis of visual acuity in traumatic optic neuropathy us-ing multivariate Logistic regression analysis. Results The mean age of patients was 33.6 ± 12.8 years and 95 cases (91.3%) were males. The injury was mainly caused by non-motor vehicle and motor vehicle accidents (84 cases, 80.8%). Most of the patients came to the hospital within 3 days after the injury (81 cases, 77.9%). Overall efficacy rate of treat-ment was 45.4%(49/108). The effective rate was 29.9%(20/67) for visual acuity without light perception and 70.7%(29/41) for visual acuity with light perception, respectively. Logistic regression analysis showed that the time to treatment≥24h, orbital hemorrhage or orbital fracture, ethmoid or sphenoid sinus bleeding and no light perception vision were an in-dependent prognostic factors. Conclusion Time to treatment time and severity of injury are the independent risk factors for poor visual prognosis of traumatic optic neuropathy whereas controlling these risk factors has important clinical signifi-cance to the treatment and prognosis of traumatic optic neuropathy.

Objective To discuss the combined value of gray-scale ultrasound ( GSUS) and contrast-enhanced ultrasound (CEUS) in the diagnosis of benign and malignant thyroid lesions and to explore the optimal diagnostic point of scoring method .Methods Ultrasound images of 178 thyroid lesions confirmed by pathology were synthetically reviewed by scoring 5 GSUS indicators including shape , orientation, interior echogenicity, halo sign, microcalcification and 6 CEUS indicators including relative arrival time of microbubbles in the periphery and interior, peak periphery and interior echogenicity, peripheral ring-enhancement, and homogeneity of enhancement .One positive indicator scored one point .The optimal diagnostic points and their clinical value were explored according to ROC curves .Results Scores of GSUS, CEUS and the combination of GSUS and CEUS were significantly different (Z =10.188,9.843,10.705,all P <0.001). Areas under ROC curves of GSUS, CEUS and the combination of GSUS and CEUS were 0.936, 0.919 and 0.964, respectively.Three or more positive GSUS indicators of five in a thyroid lesion predicted that the thyroid lesion was malignant , with the sensitivity of 79.6% and the specificity of 91.2%.Two or more positive CEUS indicators of six in a thyroid lesion predicted that the thyroid lesion was malignant , with the sensitivity of 91.8% and the specificity of 81.2%.Five or more positive GSUS and CEUS indicators of eleven in a thyroid lesion predicted that the thyroid lesion was malignant , with the sensitivity of 93.6%and the specificity of 92.3%.The areas under the ROC curve of GSUS and CEUS were 0.936 and 0.919.The area under the ROC curve of the combination of GSUS and CEUS was 0.964, larger than the areas under the GSUS ROC curve and the CEUS ROC curve.Conclusion Ultrasound is valuable in the differential diagnosis of benign and malignant thyroid lesions , and the combination of GSUS and CEUS is the most valuable with 5 points as the optimal diagnostic scoring method .

Objective:This study investigates the significance of human papilloma virus (HPV) subtype detection in opportunis-tic screening for cervical cancer in Uygur and Han women. Methods:Flow-through hybridization gene chip and thin-prep cytology test were used to detect HPV in cervical cell samples from 1140 females. A total of 428 patients had undergone cervical biopsies through colposcopy. The diagnostic results of the HPV subtype test for cervical lesions were evaluated on the basis of histology. Results:Total HPV infection rate for the 1140 cervical samples was 30.3%. The most common HPV subtypes were HPV16, HPV58, HPV52, HPV18, and HPV45. HPV52 infection rate was higher in Han women than in Uygur women, with statistically significant differences between the two (χ2=8.737, P=0.003). Among these cervical samples, the single HPV infection rate was 22.4%(255/1140), whereas the multiple HPV infection rate was 6.1% (69/1140). The sensitivity and specificity of the HPV subtype test for cervical lesions were 86.4% and 24.5%, respectively. The positive and negative predictive values were 58.5%and 59.3%. Conclusion:HPV infection subtypes in Ugyur and Han women have unique characteristics. Subtype detection is important in opportunistic screening for cervical cancer.
