Objective To investigate surgical methods of treating secondary glaucoma due to tumescent senile cataract.Methods Sixty two inpatient cases(62 eyes)who suffered from secondary glaucoma due to tumescent senile cataract underwent extracapsular cataract extraction(ECEE)or phacoemulsification combined with intraocular lens implant.The changes of the eye axis,intraocular pressure(IOP),anterior chamber angle and the depth of anterior chamber were observed.Resuls The mean eye axis length of patients suffering from secondary slaucoma due to tumescent senile cataract was significanly longer than controls.The mean iotraocular pressure of inpatients had reduced from(26.02±4.38)mm Hg preoperatively to(14.46±4.54)mm Hgpostoperatively.Anterior chamber angle was opening and depth of anterior chamber was increased after operation.Conclusioo The tnain reason of secondary glaucoma due to tumescent senile cataract is that cataract inflation leads to structural change of anterior chamber angle.This kind of glaucoma patients can be treated by purely extracapsular cataract extraction(ECCE)or phacoemulsification combined with intraoctdar lens implant without slaloms operation.

Objective To analyze the relationship between plasma copeptin level and prognosis in patients with severe acute pancreatitis(SAP).Methods The clinical data of 48 SAP patients from January 2010 to October 2014 were collected and another 48 patients who accepted healthexamination dur-ing the same period were selected as controls.Difference in plasma copeptin level was compared between groups.The results of APACHEⅡ,Ranson and modified Marshall scores were also collected to evaluate the severity of disease and the existence of MODS.The prevalence of pancreas and peripancreatic tissues effusion,necrosis,pancreas and peripancreatic abscess,pancreatic pseudocyst and mortality of the experi-mental group were recorded to analyze the relationship among plasma copeptin,complications and mortali-ty.Results The plasma level of copeptin of the experimental group was 0.83 ~5.49ng/ml,with a mean of(3.48 ±1.32)ng/ml;while in the control group,it was 0.09 ~1.46ng/ml,with a mean of(0.23 ± 0.06)ng/ml.There was significant difference between the groups(P <0.05).Patient with a high plasma copeptin level may have a higher risk for local complication,MODS and mortality,and there was significant difference between the groups(P <0.05).A ROC curve identified that a plasma copeptin level >4.02 ng/mL predicted in-hospital mortality of patients,with a sensitivity of 72.7%and a specificity of 81.0%(AUC =0.831,95%CI =1.051 ~1.679,P <0.001).Conclusion SAP patients have elevated levels of plasma copeptin,and higher copeptin levels predict high risks of complications and mortality.

Background It is determined that the patients with thyroid-associated ophthalmopathy (TAO) often occur dry-eye related symptoms due to increasing tear evaporation caused by exophthalmos.However,more than half of thyroid dysfunction patients without TAO appear ocular surface inflammation.It is very important for us to understand the association of thyroid dysfunction patients without TAO with ocular damage.Objective This study was to observe the ocular surface changes in thyroid dysfunction patients without TAO.Methods A prospective cohort study was performed.Thirty-one patients who were initially diagnosed as thyroid dysfunction without TAO were included in the Second Hospital of Tianjin Medical University from January 2015 to May 2016 as the thyroid dysfunction group,and 16 helthy subjects were simutenniously selected as the control group under the informed consent of all the individuals.The peripheral blood was collected to detect the thyroid function-related indexes.Then the patients with thyroid dysfunction were divided into thyroid stimulating hormone (TSH) reduced group (18 patients) versus TSH elevated group (13 patients) and thyrotrophin receptor antibody (TRAb)+ group (20 patients) versus TRAb-group (11 patients).Exophthalmos degree,Schirmer I test (S I t),tear film break-up time (BUT),fluorescent integral,ocular surface disease index (OSDI) and corneal inflammation index were examined and intergrouply compared.The correlations of thyroid function indexes with ocular surface examination results were analyzed.Results There were no significant differences in exophthalmos degree and S I t values between thyroid dysfunction group and control group (t =0.037,P =0.971;t =0.815,P =0.419).The BUT values were (7.74 ± 1.45) seconds and (10.56± 1.40) seconds,fluorescent integral scores were 5.00 (1.50) and 2.50 (2.38),OSDI scores were 45.58 ± 9.23 and 19.47 ± 6.25,and corneal inflammation index scores were 0.11 (0.22) and 0.00 (0.06) in the thyroid dysfunction group and the control group,respectively,showing significant differences between the two groups (all at P＜0.01).There were not significant differences in exophthalmos degree,S I t,BUT and corneal inflammation index scores between the TSH elevated group and TSH reduced group (t =0.473,P =0.640;t =0.650,P=0.521;t=1.634,P=0.l13;Z=0.270,P=0.787).The fluorescent integral scores were 4.00 (2.00) and 5.00 (1.00),and OSDI scores were 40.08±9.91 and 47.11±9.75 in the TSH elevated group and TSH reduced group,repectively,with statistically significant differences between these two groups (all at P＜0.01).The exophthalmos degrees,S I t,BUT and corneal inflammation index scores were not considerably different between TRAb-group and TRAb+ group (all at P＞0.05);and significant differences were seen in fluorescent integral scores (4.00[1.50] vs.5.50 [1.50]) and OSDI scores ([39.18±6.25] vs.[46.78±8.76]).Corneal inflammation index scores were positive correlated with serum TSH (R2 =0.520,P =0.000),and fluorescent integral scores,OSDI scores and corneal inflammation index scores were positive correlated with serum TRAb (R2 =0.587,P =0.000;R2 =0.329,P =0.024;R2 =0.400,P=0.005).Conclusions Thyroid dysfunction patients without TAO have ocular surface dysfunction,which probably is associated with abnormal serum TSH and TRAb.
