Objective To investigate the effects of zinc gluconate combined with Danshen injection on the plasma lipid level following exposure to noise in rats. Methods Fifty female SD rats were randomly divided into a control group, a noise exposure group (model group), a zinc gluconate + noise exposure group (zinc gluconate group), a Danshen injection+noise exposure group (Danshen injection group) and a zinc gluconate+Danshen injection+noise exposure group (combination group), 10 rats in each group. The zinc gluconate group received intragastric administration of zinc gluconate 8-10 mg/(kg?d), the Danshen injection group received intraperitoneal injection of Danshen injection 6 mg/(kg?d), the combination group received intragastric administration of zinc gluconate 8-10 mg/(kg?d) and intraperitoneal injection of Danshen injection 6 mg/(kg?d). On the day 10, except in the control group, the rats in the rest of the groups were continuously exposed to high frequency steady noise for 7 days (4 000 Hz, 95 dB, 3 h/d). The serum levels of total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were detected. Results The serum levels of TC (1.88 ± 0.17 mmol/L vs. 1.55 ±0.09 mmol/L), TG (1.45 ± 0.38 mmol/L vs. 1.01 ± 0.27 mmol/L), LDL-C (0.29 ± 0.04 mmol/L vs. 0.23 ± 0.03 mmol/L) in the model group were significantly lower than those in the control group (P<0.01 or P<0.05), while the serum HDL-C level in the model group were significantly lower than that in the control group (0.55 ± 0.08 mmol/L vs. 0.62 ±0.06 mmol/L;P<0.01). The serum TC level in the zinc gluconate group was significantly lower than that in the model group (1.71 ± 0.11 mmol/L vs.1.88 ± 0.17 mmol/L;P<0.05). The serum levels of TC (1.73 ± 0.21 mmol/L vs. 1.88 ± 0.17 mmol/L) and LDL-C (0.25 ± 0.03 mmol/L vs. 0.29 ± 0.04 mmol/L) in the Danshen injection group were significantly lower than those in the model group(all P<0.05). The serum levels of TC (1.57 ± 0.21 mmol/L vs. 1.88 ± 0.17 mmol/L), TG (0.84 ±0.40 mmol/L vs. 1.45 ± 0.38 mmol/L) and LDL-C (0.24 ± 0.05 mmol/L vs. 0.29 ± 0.04 mmol/L) in the combination group were significantly lower than those in the model group (P<0.01 or P<0.05), and the serum HDL-C level (0.61 ± 0.07 mmol/L vs. 0.55 ± 0.08 mmol/L) in the combination group was significantly higher than that in the model group (P<0.05). Conclusions Noise exposure may induce dyslipidemias in rats. Zinc gluconate and Danshen injection can regulate the plasma lipid level following exposure to noise in rats, and combination of zinc gluconate and Danshen injection may be superior to zinc gluconate or Danshen injection alone.

By constructing the genomic DNA library of Meiothermus ruber CBS-01, the genes of trehalose phosphate synthase (TPS) and trehalose phosphate phosphatase (TPP) involved in trehalose synthesis were cloned. The genes were cloned into the plasmid pET21a, and expressed in Escherichia coli Rosetta gami (DE3). The activities of these two purified enzymes were confirmed by thin layer chromatography (TLC). Meanwhile, we tested the cellular compatible solutes of M. ruber CBS-01 under different environmental pressure, and found that under hyperosmotic pressure, this strain can accumulate trhalose-6-phosphate, but not trehalose. These results can give more insight to future research in the roles of TPS/TPP and TreS pathway.

Objective To analyze the status quo of hospital-community-family nursing model in China, and provide reference for nursing staff to carry out relevant research.Methods The literatures concerning hospital-community-family nursing intervention in China included in databases such as CNKI, Wanfang, VIP and SinoMed since they were created until June 2016 were retrieved and analyzed using bibliometrics and content analysis.Results Totally 56 literatures were found up to standard. The first one was published in 2005, and the number of such literatures began to increase since 2012. Only 35.7% of them were published in core journals of nursing. Fund programs and literatures were consistently distributed, mainly from the eastern part of China. These literatures focused on patients with chronic diseases and those receiving maintenance treatment, most of which had no specific description of experiment randomization, sample size, intervention time, ethical issues and reliability and validity of research tools. There was a lack of assessment and training for multidisciplinary teams. Follow-up measures were single, mainly to develop discharge plans, telephone follow-up and family follow-up.Conclusions The application of the hospital-community-family nursing model in China is still in the middle of exploration. High-quality literatures, multidisciplinary team training and assessment systems, unified management of patient information, smart phone APPs as well as team rewards are badly needed to improve the quality of continued nursing.
