Follicular lymphoma (FL) is a kind of indolent non-Hodgkin lymphoma (iNHL), which origins from follicle germinal center. Multiple researches reported the latest development about treatment of FL in the 58th American Society of Hematology (ASH) Annual Meeting. The outcomes of clinical trials in which GAl01 combined with chemotherapy and bendamustine in combination with 90Y-ibritumomab tiuxetan for the advanced stage FL were exciting. Relapsed/refractory FL patients who receive tandem autologous followed by nonmyeloablative allogeneic transplantation could acquire preferable remissions. With the emerging of novel drugs including inhibitor of bcl-2 or PI3K and antibody drug conjugate, more and more improvements of efficacy and remission were made in the treatment of relapsed/refractory FL therapy and remission.

Objective To investigate the value of distinguishing small clear cell renal cell carcinoma and high-attenuation renal cysts by applying unenhanced CT value and homogeneity of the esions.Methods Retrospective analysis of 38 cases of small renal cell carcinoma confirmed by operation and pathology and 58 cases of high-attenuation renal cyst that were confirmed by enhanced CT,and measured CT value and homogeneity of each mass,and did statistical analysis for corresponding datas.Results The CT value of small clear cell renal cell carcinoma was (35.5±10.1)HU (range 20-60.3 HU).The CT value of high-attenuation renal cysts was (70±1 5.2)HU (range 29-95 HU).Difference of the two groups had statistical significance (P <0.001).For high-attenuation re-nal cysts,uniform density often can be seen(47 cases,81.03%).For small clear cell renal cell carcinoma,uneven density often can be seen (29 cases,76.32%).Difference of the two groups had statistical significance (P <0.001).When optimal cut-off of CT value determined by ROC was 5 1.5 HU,the sensitivity and specificity were 89.7% and 92.1%,respectively.Conclusion Unenhanced CT may be helpful in distinguishing small clear cell renal cell carcinoma and high-attenuation renal cysts,which can provide reasona-ble suggestions on the next identification examinations.

Objective To explore the relationship between retinal nerve fiber layer (RNFL) thickness and central corneal thickness (CCT) in myopia eyes.Methods 91 cases (91eyes) were selected from ophthalmological outpatients including 28cases with low myopia ( spherical equivalence [ SE ] ＞ -3.0D), 33 cases with moderate myopia (SE -0.3D ～ -6.0D) and 30 cases with high myopia (SE ＜ -6.0D).All patients received ocular standard examination including intraocular pressure, refraction, slitlamp biomicroscopy and fundus examination.Other ocular diseases except refractive error were excluded.RNFL thickness and CCT were measured by RTVue Fourior-OCT ( Optovue Inc, USA).Refraction diopter was shown as SE.Results The mean RNFL thickness and CCT was ( 108.5 ± 10.1 ) μm, (524.7 ±36.8)μm respectively.These were no significantly different among low, moderate and high myopia ( P ＞ 0.05 ).Temporal RNFL thickness( tl1 ,tu1 ) was significantly positive related with CCT( r =0.281,0.093 of tl1, r= 0.352,0.167 of tu1 respectively in single and multiple variable analysis; P ＜ 0.05 ), nasal ( nl2, nu2)and inferior nasal RNFL thickness( in2,in1 )was significantly positive related with SE( P ＜0.05), inferior temporal RNFL thickness( it2)was significantly negative related with SE( P ＜0.05), and RNFL thickness in other regions were not significant related with CCT and SE ( P ＞ 0.05 ) in single and multiple variable regressive analysis.Conclusion Relationship between RNFL thickness of local paradisc region and CCT in myopia eyes suggested that CCT should be correlative with some sensible structural parameters in glaucomatous neuropathy and might be important in the diagnosis and therapy of glaucoma.

BACKGROUND:With the extensive application of cone-beam CT in oral and craniofacial surgery, a clear hyoid bone position indicator for normal population has important implications for the change of hyoid bone position before and after orthodontics. OBJECTIVE:To determine the cone-beam CT measurement range of hyoid bone position in populations aged 6-19 years from Shandong, so as to provide a reference marker for the change of hyoid bone position before and after orthodontics in local children and adolescents. METHODS:Totaly 254 healthy children (120 males and 134 females) aged 6-19 years from Shandong Province were subjected to cone-beam CT scan of the hyoid bone. Mimics10.01 was used to evaluate the linear and angular measurements of hyoid bone position, and then the normal value range was confirmed. Independent-samplet-test was used for analysis of gender difference and 95% confidence interval was calculated. RESULTS AND CONCLUSION: There were gender differences in a part of indicators of hyoid bone position among 14-15 years, 16-17 years, 18-19 years groups (P < 0.05). For children aged 12-13 years, the hyoid bone position vertical to the base of skul and upper jaw bone is lower in males than in females. For children aged 14-15 years and 18-19 years, the hyoid bone horizontal to the cervical spine is more forward in males than in females.
