Purpose:To investigate the effects of tumor suppressor gene p53 on the activity of telomerase/hTERT in human HCC-9204 cell line.Methods:Lipofection-mediated gene transfection method was used to transfect wild-type p53(wt-p53) gene into HCC 9204 cell which expresses telomerse /hTERT and carries mutant-type p53 gene. The expression of p53 was confirmed by Western blot. Both the telomerase activity and hTERT mRNA expression were detected by PCR-ELISA,TRAP-silver staining,in-situ hybridization and RT-PCR methods. The apoptotic appearance was examined by FCM.Results:Higher telomerase activity and hTERT mRNA level were detected in HCC-9204,and they were markedly inhibited after transfection with wt-p53. Meanwhile,decreasing level of bcl-2 protein and appearance of apoptosis were also shown in the transfected cells.Conclusions:Over expression of the exogenous wt-p53 gene does suppress both telomrease activity and hTERT mRNA expression in HCC cell line. There is a p53-dependent regulatory pathway for activation and expression of telomerase/hTERT in HCC.

Background Idiopathic macular epiretinal membrane (IMEM) occurs probably along with vitreous macular traction syndrome (VMTS),persudo macular hole (PMH) and lamellar macular hole (LMH).Removing posterior hyaloid and completely peeling IMEM are the key to the treatment.Objective This study was to investigate the effectiveness of indocyanine green (ICG)-assisted macular epiretinal membrane combined internal limiting membrane (ILM) peeling for IMEM.Methods Twenty nine eyes of 29 patients with IMEM were collected in Affiliated First Hospital of Zhengzhou University from June 2010 to September 2012,including 16 eyes with simple macular epiretinal membrane,6 eyes with both IMEM and VMTS,3 eyes with IMEM and PMH,4 eyes with IMEM and LMH.A standard three-port pars plana vitrectomy was performed.After removal of posterior hyaloid,0.25％ ICG was used to assist IMEM and ILM peeling.The process and results were recored.Results After staining,the free boundary of the IMEM became obvious and IMEM was peeled directly in 17 of the 29 eyes (58％).In the others (42％),a free petal of ILM was made,IMEM and ILM were peeled together.In all the 29 eyes,the peeled zone could be easily recognized.No serious intraoperative complication was found.The mean postoperative follow-up was (9.65 ±7.58)months (ranged,1 to 28 months).Visual acuity was improved in 20 eyes (69％).The LogMAR vision was significantly improved in postoperation in comprison with preoperation (0.62 ±0.56 versus 0.72 ±0.67) (t =2.370,P=0.025).No IMEM recurred during the following-up duration.Conclusions ICG-assisted ILM peeling can make the surgery of IMEM safer and prevent recurrence.

Objective To evaluate the safety of mesohepatectomy for centrally located large hepatic tumors.Methods The clinical data of 37 patients who underwent hepatectomy for centrally located large liver tumors in our hospital from October 2010 to August 2015 were retrospectively analyzed.During the operation,the left and right hemilivers were mobilized.Slings for the improved liver hanging maneuver and for selective hepatic vascular occlusion were placed.These slings were used when necessary in order to minimize occlusion and ischemia time to the residual liver,and to maximize the volume of functional liver remnant.Mesohepatectomy was carried out using a microwave hemostatic separator.The feasibility,its effects on preventing hemorrhage,the degree of liver damage and the postoperative complications were evaluated.Results The mean diameter of the neoplasms was (12.6 ± 7.2) cm.The vascular inflow occlusion time of the left and right hemilivers were (12.2 ±3.5) min and (18.5 ±7.1) min,respectively.The blood loss was (487 ± 352) ml.The amount of red blood cell transfusion was (2.7 ± 1.9) U.The operation time was (215 ± 72) min.TBIL,ALT and AST reached their peak levels on the 1 st day after operation and they were higher than before surgery (P ＜ 0.01).The levels were then significantly decreased on the 3rd day after operation.However,the TBIL (P ＜ 0.05),ALT (P ＜ 0.01) and AST (P ＜ 0.05) were higher than the preoperative level,and only returned to normal or were close to the preoperative value on the 7th day after operation (P ＞ 0.05).The initial increase in ALT was quick and then it slowed down,while the initial increase in AST was slow but it decreased quickly.Conclusions Mesohepatectomy for centrally located large hepatic tumors could safely be carried out using the liver hanging maneuver combined with selective hepatic vascular occlusion and a microwave hemostatic separator.This method has the advantages of causing less bleeding,liver damage and rapid recovery.

Objective To compare the carriage of dematiaceous fungi in wild toads from both en-demic area and non-epidemic area of chromoblastomycosis.Methods A total of354and45wild toads(Bufo Chinese)were caught from two counties of Shandong Province,Zhangqiu county,an endemic area of chromoblastomycosis,and from Laiyang county,an area where the infection of dematiaceous fungi in humans has not been found,respectively.The toads were killed and the suspension of the internal organs were used to isolate dematiaceous fungi.Results Eleven species including162strains of dematiaceous fungi were iso-lated from151of354(42.7%)toads from the endemic area.The isolated strains consisted of49Phialopho-ra verrucosa,33Exsophiala,19Phialophora(nonpathogenic),19E.jenselmei,12Cladosporium carrionii,3suspected of C.carrionii,7Rhinocladiella sp.,5Fonsecaea pedrosoi,4C.trichoides,3E.spinifera,1C.mi-nourae,4unidentified.Only4nonpathogenic dematiaceous fungi were isolated from4of45(8.9%)toads obtained from non-epidemic area.Conclusions Varieties of pathogenic dematiaceous fungi,especially C.carrionii,are isolated from wild toads in endemic area of chromoblastomycosis,while none from non-endemic area.The results suggest that the colonization of pathogenic dematiaceous fungi in wild toads may be associa-ted with endemicity of chromoblastomycosis.

Objective To explore a quick and feasible method of screening malaria parasite by using a Sysmex XE-2100 hematology analyzer though alarm information on high eosinophil count and atypical eosinophil distributions in the WBC scattergram. Methods Sysmex XE-2100 hematology analyzer was used for complete blood cell analysis. Microscopic review was used when high eosinophil count and atypicaleosinophil distributions in the WBC scattergram were found. If the review showed normal eosinophil cells, wecontinued to focus on red cell for searching malaria parasite. Results Among 1 501 specimens showing higheosinophil counts and atypical eosinophil distributions, nine cases with normal eosinophil cells were indisaccordance with the hematology analyzer, six of them showed high eosinophil count in the Sysmex XE-2100 hematology analyzer, whose distribution was located close to neutrophil clusters in scattergram. The otherthree had an abnormal WBC scattergram. There was no gap between eosinophil clusters and neutrophilclusters, which brought no classified results. But all the nine specimens had been found the trophozoite,schizont and merozoite in blood smears. Conclusions There were great possibility of the existence of themalaria parasite in specimens when hematology analysis showed high eosinophil count and atypical eosinophildistributions in the WBC scattergram in a Sysmex XE-2100 hematology analyzer, although these alarm wasnot comfirmed by microscopic review. This method provides not only a simple and reliable way for quickscreening malaria parasite but also has a great value in preventing the undetected ratio on malaria parasite.

To develop a handling platform for loading, unloading, fixation, deployment, withdrawal and etc of medical materials in field conditions. Classified handling was performed for different function units with the de-vice developed, which was composed of a trolley, a railroad, a hydraulic handling board, a fixation belt and a vehicle-mounted tractor. The platform could enhance the efficiency of materials handling, which behaved well in the hos-pital without any handling device. The modular handling platform is easy to unload, carry, transport, fix and maintain, and thus is worthy popularizing practically.
