Objective To study the correlation between chemotherapy drug sensitivity and the expression of P-glycoprotein protein(P-gp),lung resistant-related protein(LRP)in different esophageal carcinoma patients,which will offer experimental evidence for clinical individualized chemotherapy of esophageal carcinoma patients.Methods Selected fresh esophageal carcinoma's tissue,Common used drugs and chemoscheme for esophageal carcinoma were used for chemosensitivity testing of the primary cultured tumor cells.At the same time,immunohistochemistry method was used to detect the expression of P-gp and LRP of esophageal carcinoma cells.Results The chemotherapy drug sensitivity of single drug was different(P<0.05).The combination of Tax and DDP had the best effect.DDP and NVB combination had a better effect than DDP and 5-FU combination.The sensitivity of DDP had no significant correlations with expression intensity of P-gp(P>0.05),and it had significant correlation with expression intensity of LRP(P<0.05).There were significant correlations between sensitivity of both NVB group and Tax group and expression intensity of P-gp and LRP(P<0.05).There was no significant correlations between sensitivity of 5-FU and expression intensity of P-gp and LRP(P>0.05).Conclusion The esophageal carcinoma chemosensitivity in vitro can indicate the sensitive drug of different patients,and guide individualized chemotherapy.The expression of P-gp and LRP has relationship with several chemotherapy drugs,which can provide base for individualized chemotherapy in clinic.

Objective To sum up clinical experiences of intractable temporal lobe epilepsy by microsurgery. Methods A retrospective review was conducted in 50 cases with epilepsy,and temporal lobe was resected by microsurgery from June 1996 to Oct. 2003. Results Follow-up patients from six months to five years.The follow up showed healing outcome in 25 cases,good results in 13 cases,unsatisfactory outcome in 9 cases,no improvement in 3 cases.Slight paresis 6 cases,divagation 8 cases,psychosis 5 cases and no death case. Conclusions Application of microsurgery can obvously improve the clinical result of patients with temporal lobe epilepsy and decrease the complication after operation.

Objective To evaluate the short-term efficacy of combination of 125 I seed brachytherapy and cetuximab in postoperation recurrent rectum cancer.Methods From July 2014 to June 2018,at Affiliated Hospital of Shandong Academy of Medical Sciences,57 patients with postoperation recurrent rectal cancer were recruited.According to therapy the patients were divided into two groups:the radiotherapy group (30 cases) treated with radioactive 125I seeds alone and the combination treatment group (27 cases) treated with combination of radioactive 125I seeds and cetuximab.The tumor size,pain relief and adverse reactions were observed in both groups.Chi-square test were performed for statistical analysis.Results After treatment for six months,the total efficacy rate and local control rate of combination treatment group were 54.2% (13/24) and 87.5% (21/24),respectively;and which were higher than those of radiotherapy group (17.9%,5/28 and 39.3%,11/28),and the differences were statistically significant (x2 =15.01 and 2.55,both P < 0.05).At one month after treatment,the pain relief rate of radiotherapy group and combination treatment group was 70.0% (21/30) and 85.2% (23/27),respectively,and there was no statistically significant difference between the two groups (P > 0.05).After treatment for six months,the rates of adverse reactions of radiotherapy group and combination treatment group were 46.7 % (14/30) and 63.0% (17/27),respectively,there was no statistically significant difference between the two groups (P > 0.05).The symptoms of patients with radiation injury significantly improved after symptomatic treatment.Conclusion The short-term efficacy of combination of 125 I seed brachytherapy and cetuximab is better than that of 125 I seed brachytherapy alone in patients with postoperation recurrent rectum cancer.
