Combination with other conventional treatments can improve the curative effect. It's a promising new method of gene therapy in head and neck neoplasms.

Purpose To study the morphological features, immunohistochemical phenotype, diagnosis and differential diagnosis of hep-atoblastoma in children. Methods The pathologic data of 58 child patients with hepatoblastoma were enrolled in this study, and histo-logical classification with distinct clinical associations were used. Prognostic data were also collected. Results Pure epithelial type was 33 cases, pure fetal type 18 cases, including 8 cases of low mitotic activity type, 9 cases of high mitotic activity, and 1 case of fo-cal pleomorphic type. 11 cases were embryonal type, 3 small undifferentiated type and 1 transitional liver cell tumor. All the 25 cases of mixed epithelial and mesenchymal type were without teratoid features, including fetal epithelial and mesenchymal type (6 cases), embryonal epithelial and mesenchymal type (17 cases), transitional liver cell tumor and mesenchymal type (2 cases). Follow-up data were available in 14 cases, in which 12 cases were sensitive to chemotherapy. Conclusions Pathologic type of hepatoblastoma rely mainly on the histology, which has a certain clinical prognostic significance. The stage of the tumor and the histopathologic type are two key prognostic factors in determining the survival of children with hepatoblastoma.

Objectives To observe the effect of flurbiprofen as preemptive analgesic and it's relative adverse reactions in pa-tients undergoing selective craniotomy .Methods Sixty patients undergoing selective craniotomy were divided into two groups randomly by age,sex,location of craniotomy:observation group (Group-flurbiprofen) and control group (Group-saline).Monitored sonoclot signal and estimate bleeding amount during the operation .Evaluated the quality of emergence after operation .Recorded the VAS pain scores 2 hours,6 hours,12 hours and 24 hours after operation ,and the occurrence of adverse reactions as nausea , vomiting and respiratory de-pression.Results The concentration of prostaglandin E2(PGE2) in the serum of the observation group was lower than that of control group( P <0.05).There were no significant differences in ACT (activated coagulation time) and CR (clot rate) of the two groups( P>0.05),but the PF (platelet function) of observation group was lower than that of control group ( P <0.05).There were no signifi-cant differences in awakening time and extubation time of the two groups ( P >0.05).The 2 hours'pain scores of the two groups was of no significant difference( P >0.05),but the pain scores of observation group were lower than that of control group in 6 hours,12 hours and 24 hours after operation( P <0.05).The occurrence of nausea , vomoting and respiratory depression had no significant differences ( P >0.05) .Conclusions Flurbiprofen as preemptive analgesic can reduce the postoperative pain in patients undergoing cranioto -my,without increasing the occurrence of nausea , vomit and respiratory depression .It can effect the platelet function ,but could not in-crease the amount of bleeding .

Objective To analyze the value of the serum BHMT for diagnosis of hepatic injury in patients with acute poisoning.Methods ELISA method was used to detect BHMT in serum samples,and the samples were detected in the sera of normal persons and patients with acute poisoning.Results 300 samples were detected in the sera of normal persons by ELISA method.The average level of human serum B HMT content in 300 samples was 9.02 ng/mL(6.19-12.84 ng/mL),and the 95 ％ medical reference value of BHMT content in healthy people ranges from 0.00 to 28.01 ng/mL.BHMT and ALT were detected in 43 samples from acute liver injury,the Spearman analysis indicating a good positive correlation between BHMT and ALT(rs =0.757 62,P＜0.001).The comparison of the content of BHMT was made between the serum samples from 20 renal damage patient and 20 normal human serum,there was no significant difference in the BHMT content between the serum of patients with renal injury and the normal human serum(P＞0.05).Conclusion The medical reference value range for of serum BHMT content in healthy population ranges from 0.00 to 28.01 ng/mL.There was a good positive correlation between BHMT and ALT.BHMT might not be closely related to kidney injury,while be more specific to liver injure.BHMT could be a better marker of acute poisoning liver injury.

Objective To compare the clinical effect of C3F8 and air tamponade after vitrectomy for the treatment of idiopathic macular hole (IMH).Methods A total of 54 eyes of 54 patients with IMH that had undergone 23G pars plana vitrectomy with internal limiting membrane peeling were retrospectively studied.All patients received optical coherence tomography ()CT) examination and the best corrected visual acuity (BCVA).They were divided into 2 groups.26 eyes in group A were filled with air and 28 eyes in group B were filled with C3F8.In group A,6 eyes at stage Ⅱ,20 eyes at stage Ⅲ,the minimum diameter (Dmin) of macular hole in 14 eyes was less than 400 μm,and in the other eyes was larger than 400 μm.In group B,10 eyes at stage Ⅱ,18 eyes at stage Ⅲ,the Dmin of macular hole in 15 eyes was less than 400 μm,and in the other eyes was larger than 400 μm.The differences of age,course of the disease,BCVA,fundus diameter,Dmin,height,index,diameter of outer retina diameter (Dord) between the two groups were not significant (P＞0.05).The basic data before surgery and the closure rate,BCVA,Dord 1 month after surgery between two groups were compared.Results At 1 month after surgery,the IMH closure rate was 100.0％ in group A and 92.9％ in group B,the difference between these two groups was not significant (P=0.491).The closure rate of eyes with Dmin＜400 μm were both 100.0％ in two groups,and the closure rate of eyes with Dmin＞400 μm were 100.0％ in group A and 84.6％ in group B.There was no statistically significant differences between two groups (P =0.480).The mean BCVA of two groups were 0.35±0.22 and 0.33 ±0.16 respectively.The mean Dord were (782.2 ± 478.0) μm and(792.1 ± 432.7) μm respectively.All cases got better BCVA (t=-7.310,-10.506;P＜0.01) and shorter Dord (t=6.704,7.770;P＜0.01).But there was no statistically significant differences between groups 1 month after surgery in BCVA and Dord (t =0.381,0.800;P =0.705,0.937).Conclusion Air tamponade after vitrectomy has the same efficacy as C3 F8 tamponade in the treatment of IMH.
