BIS Monitoring on Intraoperative Awareness: A Meta-analysis.

Intraoperative awareness is a very serious complication of general anesthesia. Several studies have evaluated the potential association between bispectral index (BIS) and intraoperative awareness, however, the results obtained were controversial. Therefore, we performed a meta-analysis to further assess the association between the BIS monitoring and the incidence of intraoperative awareness.

Inferior adaptation of bay sediments in a eutrophic shallow lake to winter season for organic matter decomposition.

Sediments in lake bays receive the greatest external pollutants mainly including terrestrial plants and river macrophyte detritus. This work investigated response and adaptation of bay sediments to organic matter (OM) decomposition under cold and hot seasons. After three month and incubated at 5 °C, it was found that the total organic carbon (TOC) removal efficiencies ranged from 15.

Increasing sulfate concentrations result in higher sulfide production and phosphorous mobilization in a shallow eutrophic freshwater lake.

Increasing sulfate input has been seen as an issue in management of aquatic ecosystems, but its influences on eutrophic freshwater lakes is not clear. In this study, it was observed that increasing sulfate concentration without additional cyanobacterial bloom biomass (CBB) addition did not have an obvious effect on element cycling during 1-year continuous flow mesocosm experiments in which water and sediments were taken from a shallow eutrophic lake with sulfate levels near 1 mM. However, following addition of CBB to mesocosms, sulfate-reducing bacteria (SRB) were observed in the water column, and increasing numbers of SRB in the water column were associated with higher sulfate input.

[The status of occupational health of female migrant workers in traditional Chinese medicine, western medicine and bio-pharmaceutical industry in Gansu province].

Objective: To understand the status of occupational health of female migrant workers in different kinds of pharmaceutical industries in Gansu province and to provide the basis for improving occupational health condition.

Methods: One thousand eight hundreds and one female workers from 16 enterprises were selected by cluster sampling in Gansu province and investigated by interviewing and questionnaires.

Results: There were statistical significances of education level, status of residency registrations, employment relationship and occupational hazards among female workers in three types of enterprises (P < 0.

[Analysis on reproductive health status and influencing factors of female workers of pharmaceutical industry in Gansu province].

Objective: To understand the reproductive health status of female workers in pharmaceutical industry of Gansu Province, to explore influencing factors, and to propose some reference basis of intervening measures.

Methods: The cluster sampling method was used to study 1801 female workers from 16 pharmaceutical industries in 6 cities (Pingliang, Qingyang, Lanzhou, Dingxi, Zhangye and Jiuquan cities) of Gansu Province. The investigation was performed by interviewing and adopting questionnaires.

[Effects of the first premolar extraction on the third molar angulation].

Objective: To analyze the effects about inclinations of the second and the third molars in patients treated with or without premolar extractions.

Methods: Fifty-six adolescents were chosen and divided into the first premolar extraction and non-extraction groups, 30 and 26 patients respectively. The pre-treatment and post-treatment panoramic radiographs were made.

Inhibitory effect of caffeic acid phenethyl ester on the growth of SW480 colorectal tumor cells involves beta-catenin associated signaling pathway down-regulation.

Aim: To study the anti-tumor effect of caffeic acid phenethyl ester (CAPE) and the influence of CAPE on beta-catenin associated signaling pathway in SW480 colorectal cancer (CRC) cells.

Methods: SW480 cells were treated with CAPE at serial concentrations. The proliferative status of cells was measured by methabenzthiazuron (MTT) assay.

The effect of Shen-Fu on gastrointestinal tract injury and its potential mechanism during cardio-pulmonary bypass in patients undergoing cardiac surgery.

Objective: To investigate the effect of Shen-Fu (SF) injection on gastrointestinal tract injury and its potential mechanism.

Methods: Thirty-eight patients undergoing elective open heart surgery were assigned to Group C (control group, n=18) and Group SF (n=20) randomly. In Group SF, the patients received intravenous injection of SF (0.
