Comparison of therapeutic effects of different acupuncture and moxibustion therapies in the treatment of peripheral facial nerve paralysis: A protocol for systematic review and network meta-analysis.

Background: Previous evidences show that acupuncture and moxibustion therapy has positive effects on peripheral facial nerve paralysis (PFP), but there are many acupuncture treatments based on meridian theory, and there are differences in the efficacy of each program. This study will compare the clinical efficacy of different acupuncture treatments for PFP through mesh meta-analysis.

Methods: Randomized controlled trials of acupuncture therapy in the treatment of PFP are going to be retrieved from 8 Science databases including CNKI, Wanfang, VIP and Chinese Biomedical Science, PubMed, Embase, Web of Science and the Cochrane Library from establishment to January 2022.

Protective Efficacy of Inactivated Vaccine against SARS-CoV-2 Infection in Mice and Non-Human Primates.

The ongoing coronavirus disease 2019 (COVID-19) pandemic caused more than 96 million infections and over 2 million deaths worldwide so far. However, there is no approved vaccine available for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the disease causative agent. Vaccine is the most effective approach to eradicate a pathogen.

Effect of diabetes mellitus on long-term outcomes of surgical revascularization in patients with ischemic heart failure: a propensity score-matching study.

Background: Diabetes mellitus (DM) is an important risk factor in the long-term outcomes of surgical revascularization. However, few studies have focused on patients with ischemic heart failure (IHF) and DM, and the results are controversial. This study aimed to evaluate the effect of DM on the long-term outcomes of IHF patients undergoing coronary artery bypass grafting (CABG).

Oceanic non-Kolmogorov optical turbulence and spherical wave propagation.

Light propagation in turbulent media is conventionally studied with the help of the spatio-temporal power spectra of the refractive index fluctuations. In particular, for natural water turbulence several models for the spatial power spectra have been developed based on the classic, Kolmogorov postulates. However, as currently widely accepted, non-Kolmogorov turbulent regime is also common in the stratified flow fields, as suggested by recent developments in atmospheric optics.

Infection with novel coronavirus (SARS-CoV-2) causes pneumonia in Rhesus macaques.

The 2019 novel coronavirus (SARS-CoV-2) outbreak is a major challenge for public health. SARS-CoV-2 infection in human has a broad clinical spectrum ranging from mild to severe cases, with a mortality rate of ~6.4% worldwide (based on World Health Organization daily situation report).

Pathogenesis of SARS-CoV-2 in Transgenic Mice Expressing Human Angiotensin-Converting Enzyme 2.

COVID-19 has spread worldwide since 2019 and is now a severe threat to public health. We previously identified the causative agent as a novel SARS-related coronavirus (SARS-CoV-2) that uses human angiotensin-converting enzyme 2 (hACE2) as the entry receptor. Here, we successfully developed a SARS-CoV-2 hACE2 transgenic mouse (HFH4-hACE2 in C3B6 mice) infection model.

Wide-range Prandtl/Schmidt number power spectrum of optical turbulence and its application to oceanic light propagation.

Light influenced by the turbulent ocean can be fully characterized with the help of the power spectrum of the water's refractive index fluctuations, resulting from the combined effect of two scalars, temperature and salinity concentration advected by the velocity field. The Nikishovs' model [ Fluid Mech. Res.

An optimized band-target entropy minimization for mass spectral reconstruction of severely co-eluting and trace-level components.

Gas chromatography-mass spectrometry (GC-MS) is a versatile analytical method but its data is usually complicated by the presence of severely co-eluting and trace-level components. In this work, we introduce an optimized band-target entropy minimization approach for the analysis of complex mass spectral data. This new approach enables an automated mass spectral analysis which does not require any user-dependent inputs.

[Long-term outcomes of off-pump coronary artery bypass grafting in patients aged over 75 years].

Objective: To investigate the long-term outcomes of off-pump coronary artery bypass grafting (OPCAB) in patients aged over 75 years and analyze the risk factors affecting the outcomes of the procedure.

Methods: Clinical data were reviewed for 97 consecutive patients aged 75 years or above receiving OPCAB at our center between November, 2000 and November, 2013. The perioperative data including length of ICU stay, duration of mechanical ventilation, incidence of postoperative complications and mortality rate of the patients were analyzed.

[Characteristics of sediment heavy metal pollution in three water supply reservoirs in Huizhou, Guangdong Province of South China].

To understand the present status of the heavy metal (Cr, Cu, Zn, Cd, Pb and Hg) pollution of the sediments in water supply reservoirs in Huizhou, sediment cores were sampled from three representative reservoirs. The heavy metal concentrations were analyzed by ICP-MS, and the pollution status was assessed by geo-accumulation index (Igeo) and potential ecological risk index (RI). In the meantime, the possible sources of the heavy metals were analyzed by the principal component analysis (PCA).

[Distribution and pollution characteristics of nutrients and heavy metals in sediments of Hedi Reservoir].

Core sediments were collected from the riverine, transition and lacustrine zones of Hedi Reservoir in southern China to investigate the spatial distributions of nutrients and heavy metals and assess the potential ecological risk of heavy metals. The total nitrogen (TN) contents of the sediments at three sampling sites are between 2.314-2.

[Analysis of therapeutic effects of external fixator for the treatment of comminuted fracture of distal radius].

Objective: To evaluate the clinical effects of external fixator in treating comminuted fracture of distal radius.

Methods: From Mar.2008 to Dec.

[46, XX testicular disorder of sex development: report of 2 cases and review of the literature].

Objective: To investigate the phenotype, pathogenesis and molecular biological features of 46, XX testicular disorder of sex development.

Methods: We obtained the history of 2 patients with 46, XX testicular disorder of sex development, examined the cavitas pelvis by type-B ultrasonography, analyzed the karyotype of the chromosome, and detected the genes SRY, YRRM1, DYS240 and DAZ by PCR amplification.

Results: Microrchidia, azoospermia and maldevelopment of secondary sex characteristics were observed in both of the patients, but ultrasonography revealed no female internal genitals.

[Azoospermia factor and male infertility].

Azoospermia factor (AZF) microdeletions of the Y chromosome, which occur in 1 - 55% of infertile men, are closely associated with severe spermatogenic failure and represent the most frequent molecular genetic causes of azoospermia and severe oligozoospermia. Researches on AZF and its related genes, approaching the mechanisms of spermatogenic failure at the molecular level, are of great significance for the diagnosis, treatment and prognosis of male infertility. The detection of AZF microdeletions can provide scientific basis for correct diagnosis and reasonable therapy.

[Qianlie Beixi capsule for unliquefiable semen: a clinical study of 180 cases].

Objective: To investigate the efficacy and possible action mechanism of Qianlie Beixi Capsule in the treatment of unliquefiable semen.

Methods: A total of 240 patients with unliquefiable semen were randomly divided into a treatment group (n = 180), treated with Qianlie Beixi Capsule, and a control group (n = 60), given compound tablets of zinc and protein. The treatment lasted two courses of 45 days each, and the seminal changes were observed and recorded.

Intranasally delivered TGF-beta1 enters brain and regulates gene expressions of its receptors in rats.

This study is aimed to evaluate the brain distribution of transforming growth factor-beta1 (TGF-beta1) following intranasal administration and the subsequent biological effects of TGF-beta1. Adult rats were given recombinant human TGF-beta1 (rhTGF-beta1) or vehicle solution intranasally. TGF-beta1 concentrations were significantly raised in several brain regions and the trigeminal nerve following intranasal delivery.
