Risk factors and prognosis of postoperative acute myocardial infarction in elderly hip fracture patients combined with coronary heart disease.

Introduction: This article mainly studies the risk factors for postoperative acute myocardial infarction (AMI) in elderly hip fracture patients combined with coronary heart disease (CHD), constructs a prediction model, and evaluates the prognosis of all the patients.

Methods: This article retrospectively collected elderly patients with hip fracture and CHD who underwent hip fracture surgery at the Third Hospital of Hebei Medical University from January 2019 to December 2021. Demographic data, laboratory indicators, and imaging examination results were collected from the medical case system.

Assessment of clinical efficacy of traditional Chinese medicine for the management of primary dysmenorrhea in the UK: A protocol of systematic review.

Background: This study aims to appraise the clinical efficacy of traditional Chinese medicine (TCM) for the management of patients with primary dysmenorrhea (PD) in the UK.

Methods: We will comprehensively search electronic databases (Cochrane Library, PUBMED/MEDLINE, EMBASE, PsycINFO, AMED, Web of Science, and CNKI) and additional resources for original articles on randomized controlled trials published in English, Chinese, German, Spanish, Korean and Japanese. Outcomes will be the pain intensity, pain duration, menstrual cramps, amount of bleeding, and severity of dysmenorrhea symptoms, quality of life, and adverse events.

Adsorption of microcystin contaminants by biochars derived from contrasting pyrolytic conditions: Characteristics, affecting factors, and mechanisms.

The growing incidence of microcystins (MCs) in the environment has become an issue of global concern for the high ecological and human health risks. Herein, a comparative adsorption of three MCs (MC-LR, MC-YR and MC-RR) by spent mushroom substrate (SMS)-derived biochars from contrasting pyrolytic conditions (temperature: 600/300 °C; and gas steam: CO2/N2) was surveyed to better understand the mechanisms and factors affecting the adsorption performance. For biochar preparation, 600 °C and CO led to greater levels of aromaticity, ash, S, and porosity, while 300 °C and N created more surface functional groups.

[Effect of SAHA on Maturation of Dendritic Cells and Its Mechanism].

Objective: To investigate the effect of SAHA on the maturation of human dendritic cells (DC) and to explore its underlying mechanism.

Methods: Peripheral blood mononuclear cells (PBMNC) were isolated from human peripheral blood and cultured in RPMI 1640 medium with 100 ng/ml rhGM-CSF and 500 U/ml rhIL-4. In the LPS induced maturation process, dendritic cells treated with or without SAHA were used as test group, and dendritic cells treated without LPS or SAHA were used as control group.

[Variation in soil Mn fractions as affected by long-term manure amendment using atomic absorption spectrophotometer in a typical grassland of inner Mongolia].

The effect of sheep manure amendment on soil manganese fractions was conducted in a 11 year experiment at inner Mongolia grassland, using sequential extraction procedure in modified Community Bureau of Reference, and determined by atomic absorption spectrophotometer. Five treatments with dry sheep manure addition rate 0, 50, 250, 750, and 1500 g x m(-2) x yr(-1), respectively, were carried out in this experiment. Results showed that the recovery rate for total Mn was 91.

Innate and adaptive host response during the initial phase of herpes simplex virus encephalitis in the neonatal mouse.

To study early events of neonatal herpes simplex virus (HSV) encephalitis and its sequelae, the authors induced a controlled infection in the brains of mice using HSVgH, a genetically modified Disabled Infective Single Cycle virus. Neonatal Balb/C mice were infected with various amounts of HSVgH- virus by intracerebral injection. Results showed that the survival of infected mice was dependent on the amount of virus injected.

Effect of resveratrol on herpes simplex virus vaginal infection in the mouse.

Resveratrol (3,5,4'-trihydroxystilbene) is a natural component of certain foods, such as grapes, that, when topically applied, has been shown to limit HSV-1 lesion formation in the skin of mice [Antiviral Res. 61:19-26, 2004]. To determine if it is active on genital HSV infection, the vagina of mice were infected with HSV-2 or HSV-1 and treated with a cream formulation of resveratrol.

Effect of topically applied resveratrol on cutaneous herpes simplex virus infections in hairless mice.

Resveratrol (3,5,4'-trihydroxystilbene) is a natural component of certain foods, such as grapes, that has been shown to have anti-herpes simplex virus (HSV) activity in vitro. To determine if it is active in vivo, the abraded epidermis of SKH1 mice were infected with HSV-1 and topically treated with 12.5 or 25% resveratrol cream or cream only.

A modification of the epidermal scarification model of herpes simplex virus infection to achieve a reproducible and uniform progression of disease.

A slight modification in the method used to remove the top keratinized layer of skin in the epidermal scarification model of HSV infection results in an easier, less painful, more uniform and reproducible means of infection. The back of mice was depilated and the top skin layer was removed either by scratching with the side of a 26 gauge needle, or by abrading with sand paper or a hand held motorized pedicure/manicure instrument. The virus was then applied on the scarified or abraded skin and the mice were observed for lesion development from day 3 to 10 post-infection.
