Reducing exposure to COVID-19 by improving access to fever clinics: an empirical research of the Shenzhen area of China.

Background: The current 2019 coronavirus disease (COVID-19) pandemic is hitting citizen's life and health like never before, with its significant loss to human life and a huge economic toll. In this case, the fever clinics (FCs) were still preserved as one of the most effective control measures in China, but this work is based on experience and lacks scientific and effective guidance. Here, we use travel time to link facilities and populations at risk of COVID-19 and identify the dynamic allocation of patients' medical needs, and then propose the optimized allocation scheme of FCs.

Gua sha therapy for chronic low back pain: A protocol for systematic review.

Background: Non-specific chronic low back pain (LBP) is a debilitating disease that profoundly impacts patients' daily physical function and quality of life. Gua sha therapy, as an easy-to-use and noninvasive complementary modality, has been widely used clinically in patients with non-specific chronic LBP. The aim of this study is to test the potential benefits and harms of gua sha therapy on patients with non-specific chronic LBP.

[Preventing role of warmth-promotion needling in reducing intracellular Ca overload of in vitro hippocampal neuronal cells of vascular dementia rats].

Objective: To investigate the underlying mechanisms of warming-promotion needling (WPN) for vascular dementia (VD) by observing its effect on the expression of L-type calcium channel current (Ica.L), changes of intracellular [Ca]i in neurons and pathomorphological changes of brain in VD rats.

Methods: One hundred and eight male SD rats were randomized into normal control, model, medication, WPN, uniform reinforcing-reducing needling (URRN), and needle-twirling groups (＝18 in each group).

[Warming-promotion needling improves learning-memory ability by up-regulating expression of hippocampal nicotinic acetylcholine receptor subunit in rats with vascular dementia].

Objective: To investigate the mechanism of Warming-promotion needling underlying improvement of vascular dementia (VD) by observing its effect on learning-memory ability and expression of hippocampal nicotinic acetylcholine receptor(nAChR)subunit proteins and mRNAs in rats with VD.

Methods: Sixty male SD rats were randomized into normal control, model, medication, warming-promotion needling(WPN), uniform reinforcing-reducing needling (URRN), and needle-twirling groups (=10 in each group). The VD model was established via repeated occlusion and reperfusion of the bilateral common carotid arteries.
