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 explore the relationship between Pglycoprotein,survivin expression and chemotherapy outcome.[Method]The expressions of P-glycoprotein,and of survivin were examined by the immunohistochemistry in 38 specimens of preoperation biopsy of osteosarecomas.[Result]The response rate of the P-glycoprotein positive group was lower than that of P-glycoprotein negative group.The response rate of the survivin overexpression group was significant lower than survivin was found to be more valuable in predicting chemotherapy results.[Conclusion]The expressions of P-glycoprotein,and of survivin are clearly associated with osteosarcomas response to chemotherapy in osteosarecoma and survivin is a more valuable parameter.

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.

Objective: To investigate the factor structure of the PTSD through analyzing the factor structure of the PTSD Checklist in adolescents from earthquake disaster region. Methods: Chinese PTSD Checklist-Civilian Version was used to assess 560 adolescents, and technique of Confirmatory Factor Analysis (CFA) was employed to comparing seven competitive models. Results: The intercorrelated four-factor model was the best fit one. Conclusion: The Chinese PTSD Checklist-Civilian has an intercorrelated four-factor model; intercorrelated four-factor model of the PTSD may fit the Chinese people, however, which needs further confirmation.

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.

[Absrt act] Obj ective To summarize the clinical experience with isolated complete resection of he-patic caudate lobe in 14 patients. Mte hods The clinical data of 14patients with isolated complete resection of hepatic caudate lobe carried out in our hospital from December 2007 to March 2015 were retrospectively analyzed .During the operation , selective hepatic vascular occlusion slings , and supra-and infra-hepatic in-ferior vena cava slings were placed after full mobilization of the liver .Isolated complete resection of the he-patic caudate lobe was performed through the left and /or the right , the anterior liver-splitting or the retro-grade approaches .Results The mean operation time was (227 ±64) min.The mean amount of blood loss was (530 ±325) ml.The mean vascular occlusion time was (19.5 ±18.6) min.The mean diameter of ne-oplasm was (15 4.±9 .2) cm. All the operations were successfully carried out .There were no massive hem-orrhage, bile leakage or perioperative death .Hydrothorax occurred in 3 patients and ascites in 2.The mean stay in hospital was (21 ±9) days.All the patients were cured and discharged home .Conclusion Isolated complete resection of hepatic caudate lobe was feasible in clinical practice .

With the extensive application of informationalized management systems for barcode specimens , the degree of informatization is becoming higher and higher in medical laboratory.Informationalized management combines modern information technology and advanced management concepts , transforms or reengineers the laboratory operation and business process.Test specimen turnaround time ( TAT) is an important factor affecting the quality of the inspection.By analyzing the test process of each time node , establish the suitable specimens monitoring program for clinical requirements and real -time monitor the key nodes in test processes ,which will effectively shorten TAT , improve reporting timeliness rate and avoid clinical complaints.
