OBJECTIVE:To investigate the correlation of patients with end stage renal disease(ESRD)and antibiotics encepha-lopathy after giving ceftazidime. METHODS:Data of 20 ESRD patients with antibiotics encephalopathy were retrospectively ana-lyzed and included into observation group,and also 20 ESRD patients with no antibiotics encephalopathy were included into con-trol group. Patients with no improved conditions in observation group were given hemodialysis associated with hemoperfusion after 2-5 days of ceftazidime withdrawal. The hemoglobin(Hb),albumin(Alb),serum creatinine(Scr),blood urea nitrogen(BUN), total cholesterol(TC),triglyceride(TG),parathyroid hormone(PTH),use time and cumulative dose of ceftazidime in observa-tion group were detected and compared with control group. RESULTS:The age,use time and cumulative dose of ceftazidime in ob-servation group were significantly higher than control group,Alb level was lower than control group,the differences were statisti-cally significant(P<0.05). 19 patients in remission and 1 died in observation group. CONCLUSIONS:The antibiotic encephalopa-thy in ESRD patients has correlation with elderly,hypoalbuminemia,use time and cumulative dose of ceftazidime.

In order to definitude the influence caused by the different sampling in voice assessment.Method:We comparing the results acquired by total section and subsection sampling.Result:The results acquired by subsection tended to normal more than those acquired by total section. Conclusion:Subsection sampling voice assessment might conceal the drgree of the disease state of patients

OBJECTIVE To construct a prokaryotic expression plasmid encoding HPV16E7-HSP70 fusion gene for further study on the immunity of HPV16E7- HSP70 fusion protein against laryngeal carcinoma. METHODS HPV16E7 was PCR-amplified,digested by NheI and SacI,and ligated into pET28a. HSP70 was cloned into pGEMTeasy,then recut from the vector by SalI and NotI and ligated into pET28a-HPV16E7. PCR amplification, restrict enzyme digestion, DNA sequencing, IPTG induction and Western Blot were used to identify the recombinant plasmid. RESULTS Double digestion and PCR amplification of the recombinant plas- mid have shown that the size of the inserted fragment is as expected. Sequence analysis has demonstrated that the inserted fragment encodes for the HPV16E7- HSP70 fusion gene. IPTG induction and Western Blot have shown that the fusion protein is expressed suc- cessfully in the prokaryotic expression plasmid. CONCLUSION The recombinant prokaryotic expression plasmid pET28a-HPV16E7-HSP70 has been con- structed successfully.

OBJECTIVE To study the expressions of heat shock protein 70 and human papillomavirus16E7 protein in human laryngeal squamous cell carcinoma, and their relationship in the genesis of human laryngeal squamous cell carcinoma. METHODS The expressions of HSP70 and HPV16E7 protein were detected by the immunohistochemical method in 78 specimens with laryngeal squamous cell carcinoma, 24 specimens with vocal cord polyps and 10 specimens of normal laryngeal tissues. RESULTS In human laryngeal squamous cell carcinoma, vocal cord polyps and normal laryngeal tissues, the positive expression rates of HSP70 were 69.2 % , 8.3 % and 0 % respectively, with those of HPV16E7 protein being 43.6 % 4.2% and 0 % respectively. There was a significant difference of the expression rate of HSP70 or HPV16E7 protein between the laryngeal squamous cell carcinoma and the vocal cord polyps(P
