ObjectiveTo explore the characteristics of phonological encoding of Chinese disyllabic compound words in patients with mild cognition impairment(MCI). Methods10 patients with MCI and 10 normal controls who matched with the age, gender, level of education and handedness performed homophone judgment task. In this task, a picture with a disyllabic compound name was presented, after 100 ms of the presentation there would be a Chinese character below the picture. Subjects were asked to judge whether one of the morpheme in the picture name was homophonic to the character. The reaction time and error ratio were analyzed statistically. ResultsIn the normal controls, the reaction time for the second constituents was shorter than that for the first constituents, while there were no difference between the first and second constituents reaction time in MCI patients. The error ratio of the first and second constituents showed no difference in normal controls, but MCI patients made more error rate for the first constituents. ConclusionAs the heathy elderly,the MCI patients have same pattern in phonological coding of Chinese disyllabic compound words, but much slower in activation speed, indicating the impairment of semantic memory and phonological activation in patients with MCI.

To study the chemical constituents of the inflorescences of Coreopsis tinctoria from Xinjiang, isolation and purification of constituents were carried out by column chromatography on macroporous resin (D101) , MCI gel, MDS gel, silica gel, Sephadex LH-20 and semi-preparative HPLC. The structures of the compounds were identified by physicchemical properties and spectral data analysis. Fourteen compounds were isolated and identified as coretinterpenoid A (1), coretinphenol (2), quercetin (3), quercetin-3-O-β-glucopyranoside (4), luteolin (5), taxifolin (6), 7, 3', 5'-trihydroxyflavanone (7), isookanin (8), isookanin-7-O-β-D-glucopyranoside (9), 5, 7, 3', 5'-tetrahydroxyflavanone-7-O-β-D-glucopyranoside (10), butein (11), okanin (12), sulfuretin (13), and linocinnamarin (14). Compound 1 was a new isabolane-type sesquiterpenoid and compounds 4, 10 and 13 were isolated from this plant for the first time.

Objective To evaluate the efficacy of eszopiclone for patients with acute insomnia and the impact of premedication with eszopiclone on sleep structure of patients with acute insomnia.Methods In an open-label,self-control trial was conducted at Changzheng Hospital Sleep Centers,and patients (n =32) with acute insomnia (12 men,20 women; mean age,36.2 years) were administered eszopiclone 3 mg for three consecutive nights.Sleep was monitored via polysomnography.The insomnia severity index (ISI),and mini-mental state examination (MMSE) were used to assess the degree of insomnia and impact of drugs on cognitive function during the day.Results Eszopiclone can shorten sleep latency ( before treatment:(52.92 ± 11.71 ) min,after treatment:(28.2 ± 10.11 ) min; t =-4.376,P ＜0.01 ),prolong total sleep time(before treatment:(365.22 ±30.13) min,after treatment:(429.18 ±26.93 ) min; t =4.102,P ＜ 0.01 ),decrease wake up times( before treatment:( 5.00 ± 1.92 ) times,after treatment:( 2.73 ± 0.91 )times; t =- 4.592,P ＜ 0.01 ),improve sleep efficiency ( before treatment:72.69％ ± 6.32％,after treatment:82.67％ ± 4.16％ ; t =3.371,P ＜ 0.01 ),reduce awake time ( before treatment:( 88.51 ±17.48) min,after treatment:(65.93 ±21.l0)min; t =-4.592,P ＜0.01 ),decrease light sleep ( NREM1 period) the percentage of time ( before treatment:12.54％ ± 2.10％,after treatment:7.30％ ± 2.90％ ;t=-3.155,P ＜ 0.01 ),and increase the percentage of slow wave sleep (before treatment:8.03％ ±5.37％,after treatment:9.31％ ±5.29％; t =4.228,P ＜0.01).No effect was observed on the percentage of NERM2 period (t =0.731,P ＞0.05) and REM period (t =-0.813,P ＞0.05).Eszopiclone can improve the quality of subjective assessment of sleep ( ISI score decreased,t =- 2.551,P ＜ 0.05) and has no significant effect on cognitive function on first the morning after patients taking the medication.Conclusion Eszopiclone can positively regulate the sleep structure in patients with acute insomnia and improve subjective assessment of sleep quality.It is safe and has no significant effect on cognitive function.

The essential medium of B115 composed of 1% tryptone, 0.25% yeast extract and 0.5% sodium chloride was determined by using an orthogonal design. The orthogonal design was also employed in testing the optimum additions. It was composed of 0.1%(NH_(4))_(2)SO_(4),1.4%K_(2)HPO_(4), 0.6% KH_(2)PO_(4) and 0.1% (Na_(3)C_(6)H_(5)O_(7)). The yield of B115 cultured in optimum medium was compared with the one in essential medium. Statistic analysis showed that the growth of B115 was most significantly improved by adding K~(+)、NH~+_(4) and (Na_(3)C_(6)H_(5)O_(7)) to essential medium. The antibacterial effect of Bacillus subtilis strain B115 on pathogenic Aeromonas was studied. The results showed different antibacterial effects of B115 on different aeromonads. There were obvious antibacterial effects on BSK-10 and CL990920, while no effect on the growth of TL970424.

Objective To understand the impact of Qionghai Lake wetland ecological protection construction on the preva?lence of schistosomiasis,so as to provide the evidence for formulating the strategies for schistosomiasis control and prevention. Methods A retrospective survey of the construction of Qionghai Lake wetland was performed,and eleven villages around the wetland were surveyed for schistosomiasis endemic situation. The influence of the wetland project on the schistosomiasis preva?lence and Oncomelania hupensis snail status were investigated. Results Before the construction of Qionghai Lake wetland,the snail elimination and extended chemotherapy for residents was performed. After the project was finished,the roads and ditches were hardened. From 2009 to 2014,the schistosome infection rate of residents declined from 0.37% to 0. No schistosome infect?ed snails were found and in recent 2 years,no snails were found. No mice were infected in the sentinel tests. Conclusions The construction of Qionghai Lake wetland effectively eliminates snails,and interrupts the transmission of schistosomiasis. Howev?er,the environment of the wetland is more suitable for snail breeding,and therefore,the surveillance still should be strength?ened.

Objective To study the effect of dampness-eliminating and spleen-strengthening Prescription (ESP) on expression levels of adiponectin (APN) , tumor necrosis factor alpha (TNF-α) , and hepatic fat content in type 2 diabetes mellitus ( T2DM) patients complicated with non-alcoholic fatty liver disease ( NAFLD) . Methods One hundred and twenty T2DM patients complicated with NAFLD were randomized into ESP group and pioglitazone group, 60 cases in each group. Based on the fundamental treatment for decreasing glucose, ESP group and pioglitazone group were given oral use of ESP and pioglitazone respectively. Twenty-four weeks constituted one treatment course. Before and after treatment, we observed the hepatic fat content, serum concentrations of APN and TNF-α, blood glucose, blood lipid, and hepatic function with the virtual touch tissue quantification technique ( VTQ) , enzyme-linked immunosorbent assay ( ELISA) , biochemical analysator respeetively in the two groups. Results After treatment, the levels of fasting plasma glucose ( FPG) , 2-hour postprandial plasma glucose ( 2hPG) , glycosylated hemoglobin ( HbA1c) fasting insulin ( FINS) , total cholesterol ( TC) , triglyceride ( TG) , low density lipoprotein cholesterol ( LDL-C) and TNF-α, and hepatic acoustic radiation force impulse ( ARFI) scores in the two groups were significantly lower than those before treatment (P<0.05) . On the other hand, the serum levels of high density lipoprotein cholesterol (HDL-C) and APN in both groups were significantly higher than those before treatment ( P<0.05) . The difference values of FINS and NF-α before and after treatneat in ESP group were higher than those in pioglitazone group ( P<0.05) . Conclusion ESP can significantly ameliorate the metabolic disorders of glucose and lipid , protect the pancreatic function and reduce hepatic fat, which is possibly related with the increase of APN level and the de-crease TNF-αlevel.
