Objective To observe the characteristics of morphosis parameter of the optic disc of physiologie large cup. Methods 100 eyes with physiologic large cup and 74 eyes with normal cup were examined by Heidelberg Retina Tomograph(HRT).The differences of morphosis parameters between two groups were analyzed comparatively on disc area(DA),cup volume(CV),cup/disc area ratio(C/DR),rim area(RA),cup volume(CV),rim volume(RV),mean cup depth(MeCD),maximum cup depth (MxCD),cup shape measure(CSM),height variation contour(HVC),mean retinal nerve fiber layer thickness(mRNFLt),and retinal nerve fiber layer cross-section area(RNFLcsa).The characteristics of the inferior.superior,nasal,and temporal quadrants of the physiologic large cups were analyzed.Results DA,CA,C/DR,CV,MeCD,CSM(P=0.00.respectively)and MxCD(P=0.04)were significantly larger in eyes with physiologic large cup than in eyes with normal cup.RA,RV,HVC,mRNFLt,RNFLcsa(P=0.00,respectively)were significantly smaller in eyes with physiologic large cup than in eyes with normal cup.The temporal quadrant of RV of the physiologic large cup is the narrowest.RNFLcsa decreased as the following order:superior,inferior,nasal,and temporal(P＜0.05).Conclusions Morphosis parameter of the optic discs of physiologic large cup has its own representation on characteristics.Compared to normal cups,physiologic large cups had larger discs but smaller mRNFLt.The nasal quadrant of DA was larger than the inferior quadrant.

AIM　To study the effect of desipramin e (DMI) on proliferation inhibition and apoptosis induction of rat glioma C6 cel ls. METHODS　Cell proliferation w as measured by MTT colorimetric assay and cells undergoing apoptosis were determ ined by electron microscope and flow cytometry. The expression of bcl-2 was eva luated by immunohistochemistry. RESULTS　DMI could result in the c oncentration-dependent inhibition of C6 cell proliferation and lead to arrest i n G0～G1 phase of cell cycle. The value of IC50 and 95% confidence lim its were 20.7(17.3～24.2) μmol*L－1.DMI（40 μmol*L－1）-indu ced apoptosis showed classical apoptotic morphology and the hypodiploid peak ap peared on the histogram of FCM in a concentration-dependent manner, which could be abrogated by cycloheximide(1.8 μmol*L－1). Meanwhile, DMI (10 μmol *L－1) could down-regulate the expression of apoptosis associated gene b cl-2. CONCLUSION　DMI could inhibit cell proliferation in a con centration dependent manner and induce typical apoptosis of C6 cells.

BACKGROUND: Three-dimensional printing to prepare a digital model can improve the accuracy of orbital fracture repair, and has a good clinical prospect.OBJECTIVE: To evaluate the effect of individualized titanium mesh based on the digital model in the reconstruction of orbital fracture.METHODS: Twelve cases of orbital fracture were admitted at the Hospital of Stomatology, Southwest Medical University from January 2014 to October 2015. CT scanning in axial, coronal, sagittal planes and three-dimensional reconstruction were performed routinely in all cases preoperatively. Digital model was designed by 3D printing technology according to the CT data. Individualized titanium mesh was shaped based on the digital model and used to repair orbital fracture. The accuracy of the reconstructed orbit was assessed based on the postoperative CT scan.RESULTS AND CONCLUSION: Postoperative CT scans showed that the implanted individualized titanium meshes were capable of accurately reconstructing the fractured orbit in all the 12 patients, and there was no infection, and titanium mesh loosening, prolapse, and rejection. With healthy eyes as controls, 11 cases of eyeball retraction were corrected completely, and only 1 case was still under correction. Diplopia symptoms disappeared in the 8 of 9 cases, and relieved in the 1 of 9 cases. Seven cases of eye movement limitation recovered postoperatively. To conclude, the individualized titanium mesh has great accuracy to repair orbital fractures in patients without serious complications,which has achieved good clinical outcomes in the orbital reconstruction.

OBJECTIVEThis study aims to evaluate the effect of customized titanium mesh, which was designed by mirror imaging and rapid prototyping technique, with Medpor applied for orbital fracture with enophthalmos.

METHODSOrbital axial, coronal, and sagittal CT scan, and three-dimension CT examination were performed routinely in. 18 cases of orbital fracture with enophthalmos preoperatively. Based on the CT data, prosthesis model was designed by reverse engineering and rapid prototyping technique. The customized titanium mesh and Medpor were applied for orbital reconstruction and enophthalmos correction. Orbital reduction and globe projection were evaluated by postoperative CT scan and clinical follow-up visits.

RESULTSCT scans revealed that the customized titanium mesh with Medpor had great accuracy to reconstruct the orbital fracture and correct the enophthalmos in all patients without serious complications. The eye and facial appearance and function recovered significantly. No serious complication occurred in the operation and after operation.

CONCLUSIONThe customized titanium mesh, based on mirror imaging and rapid prototyping technique, can accurately reconstruct the orbital fractures with enophthalmos. The application of Medpor can effectively correct enophthalmos and eyeball mobility malformation.

Objective Inhibitor of growth 1 ( ING1 ) gene has been identified as a novel candidate of tumor suppressor gene .Over-expression of ING1 plays well-established roles in numerous cell processes ,inclu-ding DNA repair and cell apoptosis .Our study is to investigate the clinical significances of expression of ING 1 in colorectal cancer ( CRC) .Methods The mRNA level of ING1 in 82 matched samples comprising primary CRC and paired non-cancerous mucosa were detected and compared by quantitative RT -PCR.Then the correlations of mRNA level of ING1 with the clinicopathological characteristics and prognosis of patients with CRC were ana -lyzed.Results (1)In the same matched tissues,the expression level of ING1 was significantly higher in normal tissues than that in cancer tissues.(2)mRNA expression of ING1 was associated with certain clinical -pathologic variables such as tumor infiltrating level ,lymphatic metastasis,distant metastasis and advancing TNM stage .(3) We obtained the expression levels ratio of cancer tissue and normal tissue and found the lower ratio has a lower Disease-Free Survival(DFS)(P<0.0001).(4)ING1,as a candidate of tumor suppressor gene ,remained a sta-tistically-significant prognostic marker in the Cox regression analysis .Conclusion Down-regulation of ING1 may be correlated tightly with the occurrence and progression of sporadic colorectal cancer .Its expression level can be used to predict prognosis of CRC .

OBJECTIVE:To observe the clinical efficacy and safety of edaravone combined with early rehabilitation in the treat-ment of cerebral hemorrhage,and to provide clinical evidence for rehabilitation management and drug treatment of cerebral hemor-rhage patients. METHODS:168 patients with cerebral hemorrhage,collected from neurology department of our hospital during Jan. 2012 to Dec. 2014,were randomly divided into observation group and control group with 84 cases in each group. Both groups re-ceived routine treatment;observation group was additionally given edaravone intravenously on the basis of routine treatment,and be-gan to receive standardized rehabilitation treatment within 48 hours after the onset of symptom;control group began to receive stan-dardized rehabilitation treatment 2 weeks after the onset of symptom. NIHSS and MMSE score of 2 groups were conducted before re-habilitation treatment,and after 4 and 12 weeks of treatment. RESULTS:There was no statistically significant difference in lesion site and clinical manifestations between 2 groups on admission(P>0.05);both NIHSS and MMSE score of observation group were better than those of control group after 4 and 12 weeks of treatment,there was statistical significance(P<0.05). CONCLUSIONS:Edaravone associated with early rehabilitation can obviously improve the prognosis of patients with cerebral hemorrhage.
