International Eye Science 2016;16(8):1474-1476
?Dry eye is a common eye disease around the world, which has highly incidence. Although there are many treatment measures for dry eye, the clinical effect is not satisfactory. There is a close relationship between inflammation and dry eye, so the researchers pay more attention on anti -inflammatory therapy, such as fluorometholone. To explore the effect of anti -inflammatory medicine on dry eye, put forward the problems and shortcomings as well, lay the foundation for further study, and provide a strong theoretical basis for the clinical use of anti-inflammatory drugs in the treatment of dry eye, the author summarizes the clinical and experimental research progress of fluorometholone on dry eye in China and abroad.

An Aspergillus sp. strain F3 was isolated and identified from the rhizosphere soil of mangrove plant, Rhizophora stylosa Griff in Dongzhai harbor mangrove forest conservation in China. In this study, the effects of media salinity and pH on the mycelial biomass and the ability of producing antibacterial metabo- lites from this isolate were carefully analyzed. Results showed that this isolate can grow well on the SDA medium with higher salinity (3%~9%) and higher pH (8~10). Under the modified culturing conditions, this isolate can secret the antibacterial and antitumor metabolites. The extracts of acetic ether were about 448 mg/L of the fermentation broth. The antibacterial activities of the acetic ether extract were analyzed with bacteria and fungus. Results showed this extract can suppress the growth of Staphylococcus aureus、S. epi-dermidis、Sarcina lutea、Bacillus subtilis and Escherichia coli with MIC of 31.3 ?g/mL, 31.3 ?g/mL, 7.8 ?g/mL, 7.8 ?g/mL and 125.0 ?g/mL, respectively. It can also suppress the growth of Candida albicans with MIC of 125.0 ?g/mL. Further studies uncovered the cytotoxicity of this extract against the tumor cells, such as ECV304, Lovo and HepG2 with IC50 of 3.45 ?g/mL, 4.88 ?g/mL and 14.31 ?g/mL respectively.

Class Ⅱa bacteriocins can be considered as the major subgroup of bacteriocins from lactic acid bacteria, not only because of their large number, but also because of their activities and potential applications. They have first attracted particular attention as listericidal compounds and are now believed to be the next in line if more bacteriocins are to be approved in the future. The present review attempts to provide an insight into general knowledge available for class Ⅱa bacteriocins and discuss common features and recent findings concerning these substances.

Background and Objectives: Stroke is the most common neurological disease in China and regulation
of lipid levels is important for secondary prevention. This study aimed to investigate the practice of
lipid lowering agents immediately after and one month following ischemic stroke in China, and to
determine the factors affecting the practice. Methods: A total of 857 patients with acute ischemic
stroke were enrolled from 11 hospitals in the Qingdao area, Northern China. Data pertaining to the
patients’ demographic, clinical data, and treatment before and after the stroke were recorded. Univariate
and multivariate logistic regression analyses were used to determine the factors associated with the
treatment at two time points: at the acute stage and at one month follow-up. Results: The frequency
of lipid lowering therapy was 50.3% (431/857) at acute stage and 41.5% (306/738) at one month.
Lipid lowering therapy at acute stage was independently and positively associated with a history of
hyperlipidemia((P=0.002, OR (95%CI): 3.784 (1.610-8.898)) and excess alcohol consumption (P=0.005,
OR (95%CI): 1.928 (1.214-3.062)), partial anterior circulation infarct classifi cation (P=0.000, OR
(95%CI): 1.974 (1.370-2.767)), and low-density lipoprotein levels ((P=0.000, OR (95%CI): 1.426
(1.170-1.739)). Lipid lowering therapy at one month follow-up was independently and positively
associated with lipid lowering therapy at acute stage ((P=0.000, OR (95%CI): 18.275 (11.476-
29.101)), and negatively with the Modifi ed Rankin Scale ≥4 at follow-up ((P=0.030, OR (95%CI):
0.568 (0.341-0.948)).
Conclusions: Lipid lowering therapy was found to be used in about half of patients during acute and
early secondary prevention of ischemic stroke in the Qingdao area of Northern China. There should
be more education efforts to the health care professionals and public to increase its use.

The killing effects of herpes simplex virus thymidine kinase gene/ganciclovir (HSV-tk/GCV) approach by the addition of several commonly clinical chemotherapeutic agents on hormone refractory prostate cancer (HRPC) cells PC-3m were investigated. After transferring of the HSV-tk gene into PC-3m cells, mRNA and protein expression of HSV-tk was detected by reverse-transcript polymerase chain reaction (RT-PCR) and strept avidin-biotin complex (SABC) immunohistochemical method. The killing effect of GCV, cisplatin (CDDP), etoposide (VP-16), vincristine (VCR), methotrexate (MTX), 5-fluorouracil (5-Fu), and suramin on PC-3m cells was evaluated by morphological assessment analysis, trypan blue exclusion assay and MTT assay respectively. Additionally, the cooperative effect of HSV-tk/GCV system combined with the above agents on the target cancer cells was determined by MTT. Furthermore, apoptosis and necrosis induced by GCV plus 5-Fu or suramin was analyzed by flow cytometry (FCM). The results showed that that there was HSV-tk mRNA and protein expression in pDR2-tk plasmid transduced PC-3m cell. Combination of GCV with VP-16, VCR, 5-Fu or suramin led to an enhanced cellular killing effect, but with CDDP resulted in a reduced one and with MTX in an approximate one. FCM revealed that synergistic use of GCV and 5-fu or suramin resulted in a rather large proportion of apoptosis and necrosis with the apoptosis index being 36.38% and 35.51%, and the proportion of necrosis being 33.05% and 28.87%, respectively. In conclusion, HSV-tk/CGV approach by addition of certain clinical available chemotherapeutic drugs brings on statistically significant enhanced cell killing over single-agent treatment. Our results highlight the potential for such new combination therapies for future treatments of HRPC.
