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.

In order to investigate the comprehensive quality differences of the seeds harvested in different growing time, and offer theoretical guide for the optimization of seeds' production technology, we analyzed the apparent size, 1 000-grain weight, water absorbency, germination indexes, postharvest embryo rate change, relatively contents of coumarins and the yield of single plant of its seeds of different harvesting time, and compared their comprehensive quality by Topsis analysis. The results showed that there existed obvious differences in yield and quality between seeds of 3 harvesting times. While the harvesting time postponed, the yield of single plant raised, and the shrunken seeds rate decreased, the quality of seedlings increased, while the contents of coumarins showed a steady increase, and the germination rate decreased. The comprehensive quality of the seeds harvested in the black ripe time rank the first place, followed by the brown ripe time and the yellow ripe time. As the harvesting time delays, the seeds' comprehensive quality increases, therefore, we could put off the seeds' harvesting time properly for the high efficient seed production.

BACKGROUND:The intestine is not only the main target attacked by sepsis but also the vital organ which mediated sepsis. The recovery of the damaged intestinal barrier structure and function is related to the occurrence and outcome of multiple organ dysfunction syndrome (MODS). How to protect and reduce the damage of the intestinal mucosa and how to promote the reconstruction of the intestinal mucosa have been the important topics in sepsis for many years. This study aimed to investigate the influential factors of intestinal mucosal reconstruction after intestinal epithelial injuryin vivo in a mouse model of sepsis.METHODS:Mice were subjected to cecal ligation and puncture (CLP) for induction of sepsis to assess intestinal mucosal damage, epithelial cell apoptosis, and transformed number of goblet cells, and to detect the concentration of TNF-α, IL-1 and TGF-β1 and TFF3 (trefoil factor 3) expression in the small intestinal mucosa. All above were performed by HE staining, western blot, ELISA and immunohistochemistry respectively. The experimental animals were divided into a sepsis group and a sham-operation group. The animals with sepsis were separately killed at 6 (7 animals), 24 (7 animals) and 48 hours (7 animals) after CLP.RESULTS:Injured intestinal mucosa was observed in the 3 groups under a light microscope, in which damage scores in the 24-hour and 48-hour groups were higher than in the 6-hour group and no difference was found between the two groups. Moreover, less of goblet cells or other epithelial cells adjacent to the injured surface migrated into the wound to cover the denuded area. The number of goblet cells was substantially decreased in the three CLP groups compared with the sham-operation group. Protein levels of IL-1 and TNF-α were significantly increased by 3-4 fold at all time points when compared with the sham-operation group, and cleaved caspase-3 by 4 fold. Although TFF3 expression was modestly increased for 6 hours after the onset of CLP, it appeared to decline at 24 hours and 48 hours as shown by Western blot. A similar tendency was observed upon TGF-β1, i.e. the protein level was not elevated at 24 hours and 48 hours, but increased modestly at 6 hours.CONCLUSIONS:Sepsis from CLP shows less restitution on the surface of injured intestinal mucosa. There is evidence that both constant inflammatory reaction and epithelial cell apoptosis may affect mucosal reestablishment of the intestine at the onset of sepsis. Mucosa after severe sepsis showed the state of high inflammation, and declined goblet cell function and mucosal reconstruction, which affected the repair of damaged intestinal barrier. Constant inflammatory reaction, and declined goblet cell function and mucosal reconstruction ability may affect the reestablishment of intestinal mucosa at the onset of sepsis.

Objective To evaluate the effect of transcranial direct current stimulation (tDCS) on post-stroke dysphagia. Methods Cochrane Library (CENTRAL), Medline, EMBASE, CBMdisc, VIP, CNKI and WANFANG Digital Journals were searched to collect randomized controlled trials (RCTs) about transcranial direct current stimulation for post-stroke dysphagia until February 2018. Two researchers independently screened literature, extracted data and evaluated the quality of the included studies. Then, meta-analysis was performed using RevMan 5.3 software. Results A total of eight RCTs were screened, including 225 patients. Compared to the control group, tDCS was effective on post-stroke dysphagia (SMD=0.71, 95%CI: 0.32~1.10, P<0.001) with safety. Conclusion tDCS could improve swallowing function of post-stroke dysphagia. Due to the limited quantity and quality of the included studies, more high quality studies are needed.

To study the effect of Tibetan medicine Zuotai on the activity, protein and mRNA expression of CYP1A2 and NAT2, three different doses (1.2, 3.8 and 12 mg x kg(-1)) of Zuotai were administrated orally to rats once a day or once daily for twelve days, separately. Rats were administrated orally caffeine (CF) on the second day after Zuotai administration, and the urine concentration of CF metabolite 5-acetylamino-6-formylamino-3-methyl-uracil (AFMU), 1-methyluric acid (1U), 1-methylxanthine (1X), 1, 7-dimethylxanthine (17U) at 5 h after study drug administration was determined by RP-HPLC. The activity of CYP1A2 and NAT2 was evaluated by the ratio of metabolites (AFMU+1X+1U)/17U and the ratio of AFMU/(AFMU+1X+1U), respectively. The protein and mRNA expression of CYP1A2 and NAT2 were determined by ELISA and RT-PCR method, respectively. After single administration of Zuotai 3.8 mg x kg(-1) and repeated administration of Zuotai 3.8 and 12 mg x kg(-1), the activity of CYP1A2 and NAT2 decreased significantly compared with control group and there was no significant difference between other dose group and control group. The protein expression of CYP1A2 was significant lower than that in control group after repeated administration of Zuotai 12 mg x kg(-1), and the mRNA expression of CYP1A2 decreased significantly compared with that of control group after single administration of Zuotai 3.8 mg x kg(-1) and repeated admistration of Zuotai 12 mg x kg(-1), separately. The protein expression of NAT2 decreased significantly compared with that of control group after single and repeated administration of Zuotai 3.8 mg x kg(-1), respectively, and the mRNA expression of CYP1A2 decreased significantly compared with control group after single administration of Zuotai 3.8 mg x kg(-1). This study found that Tibetan medicine Zuotai had significant effect on the activity, protein and mRNA expression of CYP1A2 and NAT2.

OBJECTIVEThe history of clinical application of extracorporeal membrane oxygenation (ECMO) has been more than 30 years. But in China, there were only a few ECMO centers with limited successful cases reported by the end of twentieth century. The high morbidities and mortalities in current pediatric ECMO practice are noted in China. Therefore, it is necessary to review the experience on rescue use of ECMO in critically ill pediatric patients.
METHODA retrospective analysis was done for patients who had been receiving ECMO treatment to rescue refractory cardiorespiratory failure from different causes in a hospital between July 2007 and May 2011.
RESULTA total of 12 patients were treated with ECMO; 7 of them were male and 5 female, they aged 6 days to 11 years, weighed 2.8 - 35 (17.21 ± 11.64) kg. The underlying causes of cardiorespiratory failure were as follows: two cases with acute respiratory distress syndrome (ARDS) leading to respiratory failure, 4 with failure of weaning from cardiopulmonary bypass, 3 with fulminant myocarditis, 1 with right ventricular cardiomyopathy leading to repeated cardiac arrest, 1 with preoperative severe hypoxemia, and 1 with anaphylactic shock complicated with massive pulmonary hemorrhage and severe hypoxemia. Of the 12 cases, 3 were established ECMO (E-CPR) while underwent chest compression cardiopulmonary resuscitation (CPR). The mean ECMO support time was 151.75 (15 - 572) h. Seven patients (58.33%) were weaned from ECMO, 6 patients (50.00%) were successfully discharged. Six cases had bleeding from sutures, 2 cases with severe bleeding underwent thoracotomy hemostasis, 2 presented with acute renal failure. Infection was documented in 3 cases, hyperbilirubinemia in 2 cases, lower limb ischemia in 1 case, hyperglycemia in 3 cases, disseminated intravascular coagulation in 1 case, membrane lung leakage in 2 cases, systemic hemolysis in 3 cases, oxygenator failure in 2 cases and oxygenator thrombosis in one case. During the follow-up between 6 months and 4.5 years, 5 patients survived with good quality of life, without any documented central nervous system disorders. One case survived with the right lower extremity disorder from ischemic damage. His motor function has been improved following orthopedic operation at one year after discharge.
CONCLUSIONECMO is a justifiable alternative treatment for reversible severe cardiopulmonary failure in critically ill children.

Volatile components of Fuzhou Yulu, a Chinese fish sauce, were analyzed by gas chromatography-mass spectrometry (GC-MS), and two pretreatment methods, i.e., purge and trap (P&T) GC-MS and ethyl acetate extraction followed by GC-MS, were compared. P&T-GC-MS method determined 12 components, including sulfur-containing constituents (such as dimethyl disulfide), nitrogen-containing constituents (such as pyrazine derivatives), aldehydes and ketones. Ethyl acetate extraction followed by GC-MS method detected 10 components, which were mainly volatile organic acids (such as benzenepropanoic acid) and esters. Neither of the two methods detected alcohols or trimethylamine. This study offers an important reference to determine volatile flavor components of traditional fish sauce through modern analysis methods.
