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.

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

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 efficacy of the systemic sanitary monitoring of nosocomial infection(NI) disinfection and sterilization in NI management and performance of related NI standards of Ministry of Health in hospital.METHODS To review and treat statistically spot sampling results in 12 seasons from 2004 to 2006,and to observe performance of continued improvement after taking measures.RESULTS The qualified rate of 1647 samples including autoclave sterilizer,sterilized pack,sterilized endoscope and attachment,solution for dialysis and 2% glutaraldehyde solution was 100% from 2004 to 2006;3411 bacteriological monitoring samples of air,surface of object,hands etc and 1284 samples of all kinds of disinfectants were monitored.The annual statistical results of above mentioned samples were significantly different(?2=4.11-27.37,P
