To detect the expression of the human papilloma virus (HPV) 16 and HPV18 in esophageal squamous cell carcinoma in Minnan area. Methods: Real-time fluorescence quantitative polymerase chain reaction (FQ-PCR) was applied to detect HPV DNA in 100 esophageal carcinoma sample and 100 normal tissues beside the tumor. Results:The positive rates of high-risk HPV 16 and HPV 18 infection in Minnan esophageal carcinoma and in normal tissues beside the tumor were 14.00%, 15.00%and 7.00%, 8.00%, respectively. The positive rates of lymph node and non-lymph node metastases were 40.98%and 10.25%, respectively. These re-sults exhibited statistical significance (P<0.01). HPV 16 and HPV 18 infection was uncorrelated with patient age, pathological type, and tumor grade (P>0.05). Conclusion:HPV16 and HPV 18 infection was correlated to esophageal squamous cell carcinoma in Minnan ar-eas. Such infection may also contribute to the occurrence and development of esophageal squamous cell carcinoma.

Objective To investigate whether nuclear transcription factor κB(NF-κB) through Toll-like receptors 2(TLR2) was activated by lipid-associated membrane proteins(LAMPs) of Mycoplasma genitalium.Methods LAMPs were extractded and THP-1 cells were stimulated.The activation of NF-κBp65 was detected by ELISA and the expression of TLR2 mRNA was detected by RT-PCR.Effects of TLR2 neutralizing antibody on LAMPs induced the activation of NF-κBp65 was analyzed by ELISA.After LAMPs stimulated 293T cells with the co-transfection pFLAG-TLR2,pNF-κB-luc,pRL-TK,the activity of NF-κB firefly luciferase and pRL-TK Renilla luciferase were detected by the dual-luciferase reporter gene,to analyzed the role of TLR2-mediated NF-κB activation by LAMPs in 293T cells.Results The activation of NF-κBp65 was mediated in LAMPs induced THP-1 cells and was significantly increased by LAMPs in a dose dependent manner.when LAMPs was 4.0 μg/ml,the activation of NF-κBp65 was the highest level.TLR2 mRNA expression was up-regulated by LAMPs in THP-1 cells.TLR2 neutralizing antibody could inhibit the activation of NF-κB by 60% in LAMPs stimulated THP-1.NF-κB fluorescence was significantly increased by co-transfection pFLAG-TLR2 in a dose-dependent manner. ConclusionMycoplasma genitalium-derived lipid-associated membrane proteins activate NF-κB via TLR2 and the activation of TLR2-mediated play an important role in pathogenic process of LAMPs.

Objective:To compare the clinical value of early enteral nutrition(EEN) with total parenteral nutrition(TPN) in postoperative elder patients with esophageal and cardiac cancer. Methods: 102 cases of postoperative elder patients with esophageal and cardiac cancer were randomly divided into EEN group(n=51)and TPN group(n=51).The weight loss,serum albumin, prealbumin,liver function were measured before operation and on the eighth day after operation. The anal exsufflation time, infectious complication, duration of hospital stay and treatment cost were observed. Results: The weight loss in EEN group were less than those of TPN group(P<0.05). The levels of ALT, AST, BIL and GGT in EEN group on the eighth day after operation was lower than those in TPN group(P<0.05). The anal exsufflation time and duration of hospital stay in EEN group were shorter than those of TPN group(P<0.05). The treatment cost of EEN group was significantly less than that of TPN group(P<0.05). The infectious complication rate of EEN group was lower than that of TPN group(P<0.05). Conclusion: EEN in postoperative elder patients with esophageal and cardiac cancer can decrease the postoperative infectious complication and the treatment cost, shorten the duration of hospital stay, improve nutritional status and recovery of gastrointestinal function with less side effects of liver function.

60 Candida strains were analyzed with randomly amplified polymorphic DNA(RAPD) from HIV-infected patients' oral cavity.The results showed that RAPD-PCR fingerprinting appeared from zero to five bands whose size rang from 300 bp to 2 kb with P2 primer,Candida albicans have three characteristic bands of 300 bp,400 bp and 600 bp in size,non-Candida albicans have the similar bands.They can be clas-sified five genetic clusters and 14 genotypes by Cluster Analysis,two Candida albicans(P385&P403) with fluorocytosine-resistance were classified into C1 genotype for "Squared Euclidean Distance" being 0.115,one Candida albicans(P321) and one Candida glabrata(P522) who were resistant against Amphotericin B were classified into D1 genotype for "Squared Euclidean Distance" being 0.221.So,an abundant genetic polymorphism appeared in Candida species related HIV,RAPD could be as a reference for genotype of Candida albicans;different Candida speices had some special bands,different Candida strains had similar bands in the same species;it is perhaps that some genotypes were relevant to drug resistance.

Objective To observe the therapeutic effect of intravitreal lucentis injections combined with laser photocoagulation for Coats disease.Methods This was a retrospective case series study.From August 2012 to December 2015,18 cases (18 eyes) were diagnosed as Coats disease with macular edema by FFA and OCT.All patients were treated at baseline using intravitreal lucentis injections.One week later,photocoagulation was performed by the guiding of FFA.Follow-up treatment was performed as necessary.The primary BCVA and central macular thickness (CMT) was measured postoperatively.The follow-up time was 16-24 months (mean 18.8 months).Results The mean number of lucentis injections was 2.6,and the mean number of laser treatment sessions was 1.8.The mean preoperative BCVA was (0.81 ±0.28) LogMAR,while the final visit was (0.76 ± 0.37) LogMAR (P =0.396).In 3 patients (16.7 ％),BCVA had improved by more than 3 lines,and 13 patients (72.2％)showed stable BCVA (changes within 2 lines of visual acuity),while in 2 patients,BCVA decreased by more than 3 lines (11.1％).The mean CMT improved significantly from (341.11 ±67.97) μm preoperatively to (277.83 ±51.59) μm at the fmal visit (P =0.030).Final BCVA was significantly correlated with preoperative BCVA (r =0.817,P ＜0.001).The final BCVA of patients with subfoveal hard exudates preoperatively was significantly worse than that of patients without such exudates (P =0.044).Conclusion Intravitreal lucentis injection combined with laser photocoagulation may be an effective treatment for Coats disease.It may stablize the visual acuity,decrease the CMT of Coats disease.The final BCVA is associated with preoperative BCVA and occurrence of subfoveal hard exudates.

Objective To investigate whether macrophage-activating lipopeptide-2 ( MALP-2) in-duces the expression of heme oxygenase-1 ( HO-1 ) in THP-1 cells and its possible mechanism .Methods Human monocyte cells THP-1 were cultured in vitro and then were incubated with various concentrations (0, 0.01, 0.1, 1.0 or 5.0 ng/ml) of MALP-2 for 16 h, or were stimulated by 5.0 ng/ml MALP-2 for different length of time (0 h, 4 h, 8 h, 12 h, 16 h or 24 h).The expression of HO-1 at mRNA and protein levels were detected by real-time PCR analysis and Western blot assay .The enzyme activity of HO-1 was detected by colorimetric analysis.THP-1 cells were pre-incubated with 30 μmol/L of SB203580, PD98059 and SP600125 for 30 min and then were cultured with 5.0 ng/ml MALP-2 for 16 h to investigate the role of mito-gen-activated protein kinases (MAPKs) signaling pathway in HO-1 production.After incubating THP-1 cells with 5.0 ng/ml MALP-2 for different periods of time, NF-E2-related factor 2 (Nrf2) protein was detected by Western blot assay to study the effects of Nrf2 pathway on MALP-2-induced HO-1 expression.Nrf2 and HO-1 proteins were measured by Western blot assay after transfecting THP-1 cells (1×106/well) with Nrf2 siRNA at a final concentration of 100 nmol/L.Results MALP-2 enhanced the expression of HO-1 at mRNA and protein levels as well as the enzyme activity of HO-1 in THP-1 cells in a concentration-dependent manner.The expression of HO-1 protein induced by MALP-2 was significantly inhibited by 30 μmol/L MAPKs specific inhibitors ( SB203580 , PD98059 and SP600125 ) .MALP-2 induced Nrf2 translocation at a concentration of 5.0 ng/ml.The expression of Nrf2 and HO-1 proteins were significantly decreased in Nrf 2 siRNA-transfected THP-1 cells.Conclusion MAPKs and Nrf2 signaling pathways were involved in the MALP-2 induced HO-1 expression .
