Background Combination of cataractopiesis with intraocular lens (IOL) is believed to improve the patient' s quality of life. However, 1OL power and axial length measured by traditional method in silicone-filled eye is normally bias to the actual levels. The optical coherence biometry technology has been widely used in the measurement of IOL, but little studies have been conducted to demonstrate the IOL power difference between those methods. Objective This study was to evaluate the predictability of IOL power calculations using the IOLMaster and adjusting contact ultrasound A-scan method in silicone oil-filled eyes. Methods Forty-four silicone-filled eyes of 42 patients were divided into 2 groups according to the intraocular pressure (IOP) ( group A: ≥ 10 mmHg group,29 eyes;group B:<10 mmHg group, 15 eyes). IOLMaster and ocular ultrasonic measurement were used to measure the axis length before and after silicone oil was removed. The preoperatively measured eye axis and cornea curve were used to calculate the theoretical IOL. Results In normal IOP group ( T≥ 10 mmHg,29 eyes), the precision and stability of IOLMaster for axial length ( AL ) measurements and IOL power calculations were better than adjusted ultrasound A-scan( ZIOLMasterdependent = -2. 236, P = 0. 025 ), although in low IOP group ( T< 10 mmHg, 15 eyes),there were too much differences in axial length mesurement and IOL power calculation between the IOLMaster and adjusted ultrasound A-scan, so the post-operative imformation was not predicted accurately. Conclusion For anticipatory normal postoperative IOP eyes, the refractive outcome in cataract surgery in silicone oil-filled eyes can be predicted reliably and accurately with IOLMaster. But for complicated or anticipatory unstable postoperative IOP eyes,secondary implantation of IOL would be better.

Objective: Small-cell esophageal cancer (SCEC) is a rare malignant tumor. Radiotherapy and chemotherapy have been considered as standard treatments for limited-stage SCEC (LS-SCEC). This study aimed to analyze the comprehensive treatment and prognosis of extensive-stage SCEC (ES-SCEC). Methods: We retrospectively analyzed the clinical data of 35 Patients with ES-SCEC from the Cancer Hospital of Tianjin Medical University between January 1989 and April 2012. Results:A total of 33 patients (94.3%) participated in follow-up visits. The overall survival of the patients ranged between 0.6 and 42.4 months with a median of 9.5 months. All of the patients suffered from extensive metastasis. Among these patients, 33 manifested metastasis at diagnosis and 2 showed metastasis after surgery. One-and two-year survival rates were 27.2%(9/33) and 9.0%(3/33), respectively. Univariate and mul-tivariate analysis results revealed that the number of chemotherapy cycles (≥4) is a risk factor of OS (P=0.02) and the only indepen-dent risk factor (P=0.049). Conclusions:ES-SCEC is a malignant tumor with poor prognosis. Radiotherapy could not improve patient survival. Chemotherapy combined other therapeutic procedures could be considered as an effective treatment.

Objective To assess the absorbance rate of the fat after the operation of breast augmentation of the repeated injection of low volume, using ultrasonic imaging method. Methods Thirty three patients were injected with low volume of autologous fat (50-60 ml per time) to bilateral breasts for 1-5 times and breast sonographic examination was performed to evaluate the grafted fat tissues. The thickness of the retromammary fat layer before and after each injection was measured to calculate the absorbance index. Results The 264 points of breast were measured in this study. The fat was distributed in the retro-mammary fat layers at 224 points of the breast and in the pectoralis major muscle layer at 32 points of the breast, and the others distributed in the mammary gland layer.The average thickness of the retromammary fat layer increased gradually from 0.2 cm before the first operation to 1. 0 cm after the fifth operation. The average absorbance index one month after each operation was 34 %-66 %. Conclusion The present study demonstrates that breast augmentation by repeated autologous fat graft with low volume injection at each time is applicable and satisfactory and that breast ultrasound is an accurate and simple method to e-valuate the absorbance index.

Objective To investigate the role of two-dimensional ultrasound (2DUS) and three-dimensional ultrasonography (3DUS) in the measurement of fetal frontomaxillay facial (FMF) angle. Methods FMF angle in fetuses at 11~(+0) to 13~(+6) weeks were measured with 2DUS and 3DUS respectively. The difference between measurements and reproducibility were compared, and the relationship between FMF angle measured with 3DUS and crown-rump length (CRL) was assessed.Results FMF angle was obtained in 37 fetuses. Assessable fetuses increased with increased CRL, while the values of FMF angle decreased. Qualified 3D volumes were obtained from 30/37 (81.08%) fetuses, while qualified 2D measurements were available in 18/37 (48.65%) fetuses. For the same fetus, the difference between two measurements with 3DUS was significantly less than that with 2DUS (1.68°±1.01° vs 2.78°±1.95°, P<0.01). For the 11 fetuses assessed with both methods, the values of FMF angle obtained with two methods were not significant different. There was significant negative correlation between FMF angle and fetal CRL (r=-0.540,P<0.01).Conclusion FMF angle in fetuses at 11~(+0) to 13~(+6) weeks can be achieved rapidly and accurately with 3DUS.

Objective To investigate the diagnositic value of ultrasonography in fetuses with cystic biliary malformation. Methods Three cases of cystic biliary malformation diagnosed in our hospital by prenatal ultrasound were followed up until surgery after birth. Results In all three cases.an anechoic cystic lesion was detected in the right upper abdomen at 16,26,34 weeks' gestation respectively, which were diagnosed as biliary cystic malformation by prenatal ultrasound. Two cases were confirmed as choledochal cyst by surgery, one case as biliary atresia. The maximum diameter during pregnancy of choledochal cyst were 3. 9 cm and 4.2 cm respectively, which increased steadily as gestational age advanced, with normal gallbladder in continuity with the choledochal cyst. But the largest diameter of the cyst in congenital biliary atresia was 1.7 cm and remained unchanged throughout the remaining pregnancy, the gallbladder could not be detected or an irregular small gallbladder was shown. Excision of the cyst and Roux-en-Y hepaticojejunostomy were successfully performed in all three cases. Postoperative course were uneventful. Conclusions Cyst diameter, change in size, gallbladder ultrasound pattern may allow to make a prenatal differential diagnosis of biliary tree cystic malformation. Small and stable cyst with an undetected gallbladder or small gallbladder is more suggestive of biliary atresia than choledochal cyst. Precise imaging may facilitate prenatal counseling and perinatal management. The outcomes had improved with earlier operations.
