TL;DR: The present investigation was the first to verify the hepatoprotective effect of L. alata in vitro and in vivo, and is likely related to its potent antioxidative and anti-inflammatory activity.
Abstract: The hepatoprotective activities of total flavonoids of Laggera alata (TFLA) were evaluated by carbon tetrachloride (CCl(4))-induced injury in primary cultured neonatal rat hepatocytes and in rats with hepatic damage. In vitro, TFLA at a concentration range of 1-100 microg/ml improved cell viability and inhibited cellular leakage of two enzymes, hepatocyte aspartate aminotransferase (AST) and alanine aminotransferase (ALT), caused by CCl(4). In vivo, oral treatment with TFLA at doses of 50, 100, and 200 mg/kg significantly reduced the levels of AST, ALT, total protein, and albumin in serum and the hydroxyproline and sialic acid levels in liver. Histopathological examinations revealed that liver damage were improved when treated with TFLA. Meanwhile, 1,1-diphenyl-2-picrylhydrazyl (DPPH) and superoxide radicals scavenging activities of TFLA were also determinated. To understand the exact components of TFLA responsible for the hepatoprotective effect, nine flavonoid compounds were isolated and identified from TFLA. In conclusion, the present investigation was the first to verify the hepatoprotective effect of L. alata in vitro and in vivo. The hepatoprotective action of TFLA is likely related to its potent antioxidative and anti-inflammatory activity. Neutralizing reactive oxygen species by nonenzymatic mechanisms and enhancing the activity of original natural hepatic-antioxidant enzymes may be the main mechanisms of TFLA against CCl(4)-induced injury.

TL;DR: Risk for potential exposure to BBF appears high in HCWs, and almost all of episodes are not reported, so it is urgent to establish the Guideline for Prevention and Control of Occupational Exposure to Bloodborne Pathogens among HCWs.
Abstract: Objectives
To understand current status of occupational exposure to blood and body fluids (BBF), and awareness of knowledge about occupational bloodborne pathogen exposures and universal precaution among hospital-based health care workers (HCWs).
Methods
A cross-sectional study was conducted during April to May 2004 to study incidence of occupational exposure to BBF among 1,144 hospital-based HCWs.
Results
The total incidence and the average number of episodes exposure to BBF was 66.3/100 HCWs per year and 7.5 per person per year in the past year, respectively. The incidence (per 100/HCWs per year) and the average number of episodes (per HCW per year) of percutaneous injury (PCI), mucous-membrane exposure (MME), and exposure to BBF by damaged skin was 50.3 and 1.8; 34.4 and 1.7; and 37.9 and 4.0, respectively. The leading incidence and the average number of episodes of PCI occurred in delivery room (82.6 and 1.8). The highest percentage of PCI's that occurred during the previous 2 weeks occurred during a surgical operation (22.8%). Of all sharp instruments, the suture needle contributed the highest percentage of PCI's (24.7%) among HCWs in the last 2 weeks. Over two-thirds (68.3%) of respondents were immunized with Hepatitis B vaccine; less than one-half (47%) of HCWs wore gloves while doing procedures on patients. The respondents demonstrated a lack of knowledge regarding transmission of bloodborne diseases and universal precautions.
Conclusions
Risk for potential exposure to BBF appears high in HCWs, and almost all of episodes are not reported. It is urgent to establish the Guideline for Prevention and Control of Occupational Exposure to Bloodborne Pathogens among HCWs. Am. J. Ind. Med. 52:89–98, 2009. © 2008 Wiley-Liss, Inc.

TL;DR: It is shown that dual respiratory virus or bacterial-viral co-infections can be reduced by the use of N95 respirators, which were significantly protective against bacterial colonization, co-colonization and viral-bacterial co- Infection in healthcare workers.

TL;DR: High blood pressure remains the most important individual risk factor related to CVD burden in China, and high rates of tobacco use in men and unhealthy dietary factors continue to contribute to the burden of CVD in China.
