Target of the treatment for advanced pancreatic carcinoma is always palliative without prolongation of survival time almost, therefore the aims of treatment should be concentrated on improving the quality of life and alleviateing the disease-related symptoms. We do not call for the treatment and medicines that can incur obvious adverse reaction with limited effectiveness. Interventional therapy provides superexcellent short term efficacy with alleviating the disease-related symptoms significantly, and without severe side effects and thus coincides to the principle of the treatment for advanced pancreatic carcinoma. The surpassing advantages provide popular recommendation for this very kind of therapy in the recent years.

Late intraocular lens dislocation is one of the most severe late complications after phacoemulsification.It often occurs 3mo after the surgery.Different from early intraocular lens dislocation, late intraocular lens dislocation is caused by zonular dehiscence and contraction of the capsular bag many years after phacoemulsification.In recent years, the incidence of late intraocular lens dislocation gradually increases, having a risk of 0.1% after 10a and 1.7% after 25a.In the long-term follow-up patients who underwent cataract surgery, 90% had zonular insufficiency and capsular contraction.Among the multiple factors which may contribute to zonular weakness and capsular contraction, pseudoexfoliation is the most common cause, accounting for 50% of all the cases.Other risk factors include aging, high myopia, uveitis, trauma, previous vitreoretinal surgery, retinitis pigmentosa, diabetes mellitus, atopic dermatitis, previous acute angle-closure glaucoma attack, and connective tissue disorders.The understanding of these predisposing factors will suggest necessary preventions for high-risk patients in the future.

Objective To explore the risk factors of esophageal cancer and these factors' interaction Methods 472 new diagnosed cases of esophageal cancer in 2004—2005 and 472 controls were investigated by case-control study. Etiological fractions and interactions between family history of esophageal cancer and other risk factors of esophageal cancer were analyzed. Results The significant independent risk factors included taking hot-meal, preferring pickled-vegetables, preferring dry-rigidity-food, being irritable, drinking polluted-water perennially, family history of esophageal cancer and drinking alcohol a great deal. The etiologic fractions attributable to interaction were 0.855, 0.758, 0.683, 0.464, 0.459, 0.343 and 0.108 respectively. The synergy indexes of family history of esophageal cancer with taking hot-meal and with preferring dry-rigidity-food were both 0.86. Concludes The interactions between family history of esophageal cancer and ill life-behavior-style or drinking polluted-water perennially were particularly significant in the development of esophageal cancer in Dongping County.

Objective To study clinical significance of S-100B protein in umbilical cord blood of asphyxial neonates with hypoxic-ischemic encephalopathy(HIE).Methods Forty-three cases of healthy infants were regarded as control group(group 1).Sixty cases of asphyxial neonates were divided into two groups(44 cases without HIE as group 2;another 16 cases with HIE as group 3).S-100B protein levels in umbilical cord blood of three groups were measured with enzyme-linked immunosorbent assay retrospectively. Results Levels of S-100B protein in group 1,group 2 and group 3 were(1.055?0.356) ?g/L,(1.572?0.533) ?g/L and(2.394?(0.943) ?g/L,) respectively.S-100B protein levels in umbilical cord blood of group 2 and group 3 were significantly higher than that of group 1(t=2.306,7.991 P

Objective To evaluate the value of the mRECIST criteria in assessing the efficacy of transcatheter arterial chemoembolization(TACE) combined with sorafenib in the treatment of hepatocellular carcinoma (HCC).Methods A total of 35 patients who were treated with a combination of TACE and sorafenib for unresectable hepatocellular carcinoma fulfilled the mRECIST and RECIST criteria in our hospital from June 2011 to November 2012.Enhanced CT and/or enhanced MRI were used before (baseline) and after (3 month reexamination) combination treatment in our hospital.The mRECIST and RECIST criteria were used to evaluate the efficacy,and these efficacy assessments were compared.Results In the RECIST criteria,complete remission (CR) was 0％,partial remission (PR) was 2.9％,stable disease (SD) was 85.7％％,and progressive disease (PD) was 11.4％％.In the mRECIST criteria,CR was 8.6％,PR was 51.4％,SD was 34.3％,and PD was 5.7％.For the RECIST criteria,the objective response rate (CR+-PR) was 2.9％,the disease control rate (CR+PR+SD) was 88.6％,and the disease progression rate was 11.4％.For the mRECIST criteria,the objective criteria was 60％,the disease control rate was 94.3％,and the disease progression rate was 5.7 ％.The difference between the efficacy assessment results of mRECIST and RECIST was statisti cally significant(P＜0.001).Conclusion The mRECIST criteria can evaluate the efficacy of target le sions based on viable tumors,which is more adaptive to TACE and targeted drugs with new mecha nisms.

Objective To evaluate the efficacy of transarterial interventional therapy (TAIT) in treating patients with metastatic liver cancer, and to investigate the factors influencing the prognosis of patients. Methods From January 1997 to June 2000, 470 patients with metastatic liver cancer had undergone TAIT 1231 times in the Cancer Hospital of the Chinese Academy of Medical Sciences. The clinical data of the patients were retrospectively analyzed. The short-term and long-term efficacy and the side effect of TAIT were assessed. The potential factors influencing the prognosis of the patients were determined by Cox regression analysis. Results Complete remission was observed in 94 patients, and partial remission in 143. The total effective rate was 50.4% (237/470). The median survival time was 13.5 months. The O. 5-, 1-, 2-, 3-, 5-year survival rates were 86.4%, 66. 8%, 35.6%, 16.9%, 7.3%, respectively. No severe complication occurred. The factors influencing the prognosis of the patients were: the resection of the primary tumor, blood supply of the tumor, multiple metastases of liver cancer, thrombus in the portal vein, adjuvant chemotherapy after TAIT, tumor originated from breast cancer, tumors invading multiple lobes, concurrent metastasis in other sites (X2= 17. 322, 12. 593, 8.721, 8.573, 8.492, 7. 838, 5. 623, 5. 463, P < 0.05). Conclusions TAIT is an effective palliative therapy for metastatic liver cancer which cannot be resected. The factors mentioned above influence the prognosis of patients after TAIT.
