With GC-MS、LC-UV and gene analysis,we studied Pseudonomas sp.W2 metabolic pathway of bisphenol A(Bpa).It was discovered that 4'-(trimethylsiloxy)-Acetophenone、p-Hydroxy benzaldehyde and p-Hydroxy benzoic acid are medium metabolites and that the bacteria has pcaG.

Background Wearing of soft contact lens,as one of the important methods to correct ametropia,has been widely applied at present.The clinically deleterious effects of soft contact lens have been reported,but researches about influence of apoptosis of corneal epithelial cells are scant.Objective This study was to detect and compare the ratio of apoptosis of corneal epithelial cells between the patients with contact lens wearing and without contact lens wearing,and explore the influence of soft contact lens wearing for long term on growth of corneal epithelial cells after injury.Methods A retrospective nest case-controlled study was designed.Forty eyes of 20 myopic patients with wearing of soft contact lens for ≥5 years and 40 eyes of 20 myopic patients without wearing of soft contact lens were included in Affiliated Hospital of Guiyang Medical College.All the patients received the off-flap epipolis laser in situ keratomileusis (Epi-LASIK) from 2010 October to 2011 June.The corneal flaps were collected during the surgery.The apoptosis of corneal epithelial cells was detected by flow cytometry(FCM),and the difference of apoptotic proportion between the two groups was compared using independent sample t test.Results The FCM scatter plot showed that compared to the without contact lens wearing group,the early stage of apoptotic cells with high staining annexin V and low staining proaium iodide (PI) were much more,and survival cells with low staining annexin V and PI were less,and necrotic and late stage of apoptotic cells with high staining of annexin V/PI were more in the with contact lens wearing group.The early stage of apoptosis proportion of corneal epithelial cells was (11.23 ± 5.31)％ in the with contact lens wearing group,and that in the without contact lens wearing group was (7.31± 5.43)％,showing a significant difference between them (t=2.754,P=0.008).Conclusions A long term wearing of contact lens induce more apoptosis of corneal epithelial cells,which can result in a disorder of structure and function of ocular surface during the wound healing stage.

AlM: To observe the treatment efficacy of eyelid herpeszoster with external use ganciclovir ophthalmic gel.METHODS:A total of 77 patients were randomly divided into treatment group and control group. ln the treatment group, ganciclovir ophthalmic gel was topical coated on the basis of antiviral drugs, while the control group was coated with conventional acyclovir ointment and antiviral treatment.
RESULTS: The cure rate was 95% in the treatment group, and the control group was 83% after 10d treatment. The difference was significant.
CONCLUSlON: The efficacy of ganciclovir ophthalmic gel treated eyelid herpes zoster is obvious.

This study is to investigate the protective effect of mangiferin on NF-kappaB (P65) and IkappaBalpha expression in peripheral blood mononuclear cell (PBMC) in rats with cigarette smoke induced chronic bronchitis. The rat model with chronic bronchitis was established by cigarette smoke. Real-time fluorescence RT-PCR was executed for evaluating the NF-kappaB (P65) and IKkappaBalpha gene expression in mononuclear cell, and flow cytometry for their protein expression. The serum hs-CRP (high-sensitivity C-reactive proteins) and TNF-alpha (tumor necrosis factor-alpha) were detected by enzyme-linked immunosorbent assay. The histopathological score was obtained from lung tissue HE staining slides of lung tissue. The results showed that mangiferin could markedly suppress the NF-kappaB (P65) mRNA and protein expression in mononuclear cell, while promote the IkappaBalpha mRNA and protein expression. Furthermore, mangiferin could lower serum hs-CRP and TNF-alpha level, and reduce the chronic inflammatory damage of bronchiole. These results suggested that mangiferin could notably ameliorate chronic bronchiole inflammation induced by cigarette smoke, and this protective effect might be linked to the regulation of NF-kappaB (P65) and IkappaBalpha expression in mononuclear cell.

BACKGROUND:Metabolic characteristics of the 800 meters race is not very clear, which creates a lot of obstacles for the exercise training of 800 meters race. OBJECTIVE: To investigate the characteristics of material and energy metabolism of 800 meters race, to improve the scientific training of the 800 meters race and to verify the feasibility of nuclear magnetic resonance-based urine metabonomics in sports training monitoring. METHODS: Seven middle distance athletes were subject to an 800 meters race at ultimate intensity, and their urine metabonomics analysis was conducted in combination with the Human Metabolism Database and other databases before and after exercise. RESULTS AND CONCLUSION:OPLS-DA model showed that the metabolic samples before and after movement presented the cluster-like distribution. The change was mainly caused by the folowing metabolites, including leucine, lactic acid, creatinine, succinic acid, hypoxanthine, and adenosine. Through the analysis we could infer that the 800 meters race is a sport event mainly dependent on glycolysis for energy supply, working together with raw phosphate and aerobic oxidation for energy supply. The amino acid metabolism and methane metabolism of the athletes were more vigorous after 800 meters running, and moreover, there were certain oxidative stress during the 800 meters race. These findings indicate that nuclear magnetic resonance-based urine metabonomics takes the advantages of invasive, high sensitivity, less sample requirement, simple processing.

Objective To investigate the clinical effect of preoperative nutritional treatment and perioperative nutrition support for the patients with esophageal cancer.Methods According to the digital table,90 patients with esophageal cancer were divided into the control group(15 cases),preoperative nutrition group(25 cases),postoperation nutrition group(25 cases)and preoperative nutrition + postoperation nutrition group(25 cases).The postoperative quality of life and the complications were compared.Results Postoperative quality of life in the preoperative nutrition group,postoperation nutrition group and preoperative nutrition + postoperation nutrition group were all better than that in the control group(t =14.76,15.13,17.87,all P ＜ 0.05).The incidence rate of postoperative complications in patients received nutritional intervention significantly decreased than in the control group(x2 =9.17,12.13,19.18,all P ＜ 0.05).Conclusion The preoperative nutrition and postoperation nutrition can improve the postoperative quality of life and reduce the incidence rate of the complications.
