Background Measurement of ciliary sulcus distance is important for phakic intraocular lens implantation.Suowei panoramic 50-MHz digital ultrasound biomicroscopy makes it possible for the direct measurement of ciliary sulcus distance.Objective The aim of this study was to investigate the correlation between anterior chamber(AC)angle diameter and ciliary sulcus distance in different AC depth population and offer a clinical guide.Methods The anterior chamber angle diameter and ciliary sulcus distance were measured in 30 right eyes with shallow anterior chamber caused by suspect glaucoma and 30 right eyes with deep anterior chamber dut to the high myopia with Suowei panoramic 50-MHz digital ultrasound biomicroscopy.Three horizontal B-scans with the focal plane approximately at a depth corresponding to the iris plane were acquired for each eye.The differences of the anterior chamber angle diameter and ciliary sulcus distance were calculated and compared between the two groups.The correlation of the anterior chamber angle diameter and ciliary sulcus distance were evaluated in respective group.Results In shallow AC group,the mean angle diameter was(11.49+0.75)mm,the mean ciliary sulcus distance was (10.97±0.86)mm with the mean standard deviation of the difference of(-5.14± 0.55)mm,showing a statistically significant difference(t =-5.092,P =0.000).In shallow AC group,linear regression analysis showed a statistically significant correlation between ciliary sulcus distance and angle diameter(R2=0.593,P=0.000)and the Pearson's correlation coefficient was 0.767.In deep AC group,the angle diameter was(12.69±0.67)mm;while ciliary sulcus distance was(12.31 ± 0.61)mm with the mean slandard deviation(-0.38 ± 0.17)mm,which was statistically significantly different(t=-5.531,P=0.000).The ciliary sulcus distance was found to be linear correlation with the angle diameter(R2 =0.699,P=0.000)and Pearson' s correlation coefficient of 0.836.Conclusions Panoramic ultrasound biomicroscopy is an useful tool to the measurement of ciliary sulcus distance.This study exhibited that the ciliary sulcus distance is significant associated with the anterior chamber angle diameter,which may offer a guide for phakic intraocular lens implantation.

Objective To assess the effect of radioiodine-131 (131Ⅰ) on treatment of pulmonary metastases from differentiated thyroid carcinoma and the main prognostic factors. Methods Five databases were retrieved and all published studies which analyzed the effect of 131Ⅰ on pulmonary metastases from differentiated thyroid carcinoma and the main prognostic factors were systematically reviewed. The data about the impact of 131Ⅰ treatment and the main prognostic factors on the 5-yr and 10-yr survival rates of the patients were abstracted. RevMan 4.2 software was used to statistically analyze. Results Eleven retrospective cohort studies were included. The pooled results suggested that the 5-yr survival rates of the patients who received 131Ⅰ therapy and who did not received 131Ⅰl therapy were 74.9% and 27.1% , respectively ;The lO-yr survival rates(P<0.01)of the two groups were 60.8% % 12.2% , respectively;The difference between them had statistical significance (P<0.01). The 5-yr and 10-yr survival rates of the patients only with pulmonary metastases were higher than those of the patients with multiple metastases (P<0.01). The 5-yr (P = 0.01) and 10-yr (P = 0. 002)surviv10al rates of the patients only with papillary thyroid carcinoma were higher than those of the patients with follicular thyroid carcinoma. The 5-yr and 10-yr survival rates of male and female patients were similar(P>0.05). Conclusions 131Ⅰ treatment increases the 5-yr and 10-yr survival rates of patients with pulmonary metastases from differentiated thyroid carcinoma. The extent of metastases and the histologie type of differentiated thyroid carcinoma are two main predicting factors of prognosis. The 5-yr and 10-yr survival rates of patients are not influenced by gender.

Objective To evaluate two treatment methods for bilateral upper urinary tract transitional cell carcinomas (TCCs). Methods Clinical data of 43 patients with bilateral upper urinary tract TCCs treated in our hospital from 1994 to 2006 were analyzed retrospectively. Of them, 13 patients underwent bilateral nephroureterectomy and the rest 30 patients received unilateral nephroureterectomy and contralateral organ-preserving surgery, including partial nephrectomy, partial pelvectomy, partial ureterectomy+end-to-end ureteral anastomosis, distal ureterectomy+reimplantation and endoscopic resection. The data were analyzed and compared between the two groups using SPSS software. Results There were no statistical differences between two groups in age, gender, incidence of hematuria, low back pain and abdominal pain, smoking, number of tumor, tumor stage, tumor grade, recurrence time, recurrence rate, survival time, survival rate, or taking aristolochic acid drugs (P>0.05). Significantly higher post-surgical costs and lower survival condition satisfaction score were found among the patients undergoing bilateral nephroureterectomy, showing a significant statistical difference between the two groups (P<0.001). Conclusions For synchronous or metachronous bilateral upper urinary tract TCCs, bilateral nephroureterectomy results in similar clinical outcomes compared with that of unilateral nephroureterectomy + contralateral organ-preserving surgery, but the latter costs lower postoperative expenses and higher life quality, therefore it is worthy to be popularized.

Radioiodine therapy of carcinoma could be mediated by transferring the genes which participate in the process of iodine metabolism in thyroid. The correlative genes are sodium/iodine symporter gene, thyroid peroxidase gene and the specific thyroid transcription factors, and others. The objective gene can specifically express in carcinoma by inserting the tissue-specific promoter/enhancer upstream of them, so radioiodine could be used to treat varied carcinomas. The radioiodine uptake in carcinoma cells was obviously increased and the radioiodine therapy of carcinoma was effective after those genes had expressed in carcinoma cells. The main problem was that the effective half-time of radioiodine in cells was too short to produce the ideal effect of radioiodine therapy. Moreover, 211At and 188Re could be transferred by sodium/iodine symporter and they could be used to treat the carcinoma that is capable of radioiodine uptake.
