Aberrant expression of miR-199a in newborns with hypoxic-ischemic encephalopathy and its diagnostic and prognostic significance when combined with S100B and NSE.

Neonatal hypoxic-ischemic encephalopathy (HIE) is a disorder mainly due to asphyxia during the perinatal period, and late diagnosis leads to high mortality. In this study, the expression of microRNA-199a (miR-199a) in HIE newborns was investigated, as well as its clinical significance in HIE diagnosis and prognosis. Circulating levels of S100B and NSE in HIE newborns were measured using enzyme-linked immunosorbent assay, and the expression of miR-199a was analyzed using quantitative real-time PCR.

Ginsenoside Rd attenuates blood-brain barrier damage by suppressing proteasome-mediated signaling after transient forebrain ischemia.

Ischemic stroke damages the blood-brain barrier (BBB), which leads to brain edema and increases the risk of intracranial hemorrhage. Proteasome inhibition has been found to protect the BBB against cerebral ischemia by suppressing neuroinflammation-mediated matrix metalloproteases-9 (MMP-9) activation. We recently showed that ginsenoside Rd (Rd), a major active ingredient of Panax ginseng, could suppress proteasome-mediated inflammation and be efficient for treating ischemic stroke but downstream mechanisms were still unidentified.

Lessons on malaria control in the ethnic minority regions in Northern Myanmar along the China border, 2007-2014.

Background: For many countries where malaria is endemic, the burden of malaria is high in border regions. In ethnic minority areas along the Myanmar-China border, residents have poor access to medical care for diagnosis and treatment, and there have been many malaria outbreaks in such areas. Since 2007, with the support of the Global Fund to Fight AIDS, Tuberculosis and Malaria (GFATM), a malaria control project was introduced to reduce the malaria burden in several ethnic minority regions.

Effectiveness and impact of the cross-border healthcare model as implemented by non-governmental organizations: case study of the malaria control programs by health poverty action on the China-Myanmar border.

Background: In the Yunnan province of China, 18 counties in six prefectures border Myanmar. Due to its particular combination of geographic features, climate conditions, and cultural landscape, the area provides a suitable environment for the spread of insect-borne diseases such as malaria. In five identified Myanmar Special Regions along the China-Myanmar border, economic development is lagging, people live in extreme poverty, and the healthcare system is fragile.

Investigation and control of a Plasmodium falciparum malaria outbreak in Shan Special Region II of Myanmar along the China-Myanmar Border from June to December 2014.

Background: From 2007 to 2013, intensive control measures reduced malaria burden by 90 % along the China-Myanmar border. However, despite these measures a P. falciparum malaria outbreak was reported in the Shan Special Region II of Myanmar in June of 2014.

Human B cells have an active phagocytic capability and undergo immune activation upon phagocytosis of Mycobacterium tuberculosis.

The paradigm that B cells are nonphagocytic was taken for granted for a long time until phagocytic B cells were found in early vertebrate animals. Thereafter, limited evidence has shown that human B cells may also internalize bacteria. However, whether human B cells can actively phagocytose bacteria has been less extensively investigated; in particular, the mechanisms and significance of the phagocytosis require clarification.

Treatment of Rivaroxaban versus Aspirin for Non-disabling Cerebrovascular Events (TRACE): study protocol for a randomized controlled trial.

Background: Transient ischemic attack (TIA) or minor ischemic stroke represents the largest group of cerebrovascular disease, and those patients have a high risk of early recurrent stroke. Over decades, anticoagulation therapy has been used prudently in them for likely increasing the risk of intra-/extra-cranial hemorrhagic complications. However, recently rivaroxaban, a new oral anticoagulant, is proved to be as effective as traditional anticoagulants, while carrying significantly less risk of intracranial hemorrhage.

Ginsenoside Rd Is Efficacious Against Acute Ischemic Stroke by Suppressing Microglial Proteasome-Mediated Inflammation.

A great deal of attention has been paid to neuroprotective therapies for cerebral ischemic stroke. Our two recent clinical trials showed that ginsenoside Rd (Rd), a kind of monomeric compound extracted from Chinese herbs, Panax ginseng and Panax notoginseng, was safe and efficacious for the treatment of ischemic stroke. In this study, we conducted a pooled analysis of the data from 199 patients with acute ischemic stroke in the first trial and 390 in the second to reanalyze the efficacy and safety of Rd.

Involvement of cannabinoid receptors in infrasonic noise-induced neuronal impairment.

Excessive exposure to infrasound, a kind of low-frequency but high-intensity sound noise generated by heavy transportations and machineries, can cause vibroacoustic disease which is a progressive and systemic disease, and finally results in the dysfunction of central nervous system. Our previous studies have demonstrated that glial cell-mediated inflammation may contribute to infrasound-induced neuronal impairment, but the underlying mechanisms are not fully understood. Here, we show that cannabinoid (CB) receptors may be involved in infrasound-induced neuronal injury.

MicroRNAs as Potential Biomarkers for Diagnosing Cancers of Central Nervous System: a Meta-analysis.
