Electromagnetic field and cardiovascular diseases: A state-of-the-art review of diagnostic, therapeutic, and predictive values.

Despite encouraging advances in early diagnosis and treatment, cardiovascular diseases (CVDs) remained a leading cause of morbidity and mortality worldwide. Increasing evidence has shown that the electromagnetic field (EMF) influences many biological processes, which has attracted much attention for its potential therapeutic and diagnostic modalities in multiple diseases, such as musculoskeletal disorders and neurodegenerative diseases. Nonionizing EMF has been studied as a therapeutic or diagnostic tool in CVDs.

[Serum metabolomics of Tibetan medicine Ershiwuwei Songshi Pills against chronic cholestasis in mice].

A chronic cholestasis model was induced in mice by feeding a diet containing 3,5-diethoxycarbonyl-1,4-dihydro-2,4,6-trimethylpyridine(DDC). The effects of Ershiwuwei Songshi Pills(ESP) on endogenous metabolites in mice with chronic cholestasis were investigated by metabolomics analysis based on liquid chromatography-mass spectrometry(LC-MS). The results showed that ESP was effective in improving pathological injury and reducing serum levels of alanine aminotransferase(ALT), aspartate aminotransferase(AST), alkaline phosphatase(ALP), and total bile acid in the model mice.

[Mechanism of Tibetan medicine Ershiwuwei Songshi Pills against liver injury induced by acetaminophen in mice based on Keap1/Nrf2 and TLR4/NF-κB p65 signaling pathways].

The present study investigated the mechanism of the Tibetan medicine Ershiwuwei Songshi Pills(ESP) against the liver injury induced by acetaminophen(APAP) in mice based on the kelch-like ECH-associated protein 1(Keap1)/nuclear transcription factor E2 related factor 2(Nrf2) and Toll-like receptor 4(TLR4)/nuclear factor-kappa B(NF-κB) p65 signaling pathways. Kunming mice were randomly divided into a blank control group, a model group, an N-acetyl-L-cysteine(NAC) group, and high-(400 mg·kg~(-1)), medium-(200 mg·kg~(-1)), and low-dose(100 mg·kg~(-1)) ESP groups. After 14 days of continuous administration, except for those in the control group, the mice were intraperitoneally injected with 200 mg·kg~(-1) APAP.

[Mechanism of Tibetan medicine Ershiwuwei Songshi Pills in regulating intestinal flora and improving non-alcoholic steatohepatitis].

This study aimed to investigate the effect of Tibetan medicine Ershiwuwei Songshi Pills(ESP) on the intestinal flora of non-alcoholic steatohepatitis(NASH) mice. Forty-eight male C57 BL/6 mice were randomly divided into the control group, model(methionine-choline-deficient, MCD) group, high-(0.8 g·kg~(-1)), medium-(0.

[Development and Application of Automatic Analysis and Surveillance Platform for Chrimerism in Donors and Recipients after Allo-HSCT].

Objective: To develop an automated chimeric analysis and reporting platform based on short tandem repeat (STR) and capillary electrophoresis methods for allogeneic hematopoietic stem cell transplantation (allo-HSCT) so as to improve work efficiency.

Methods: Apache, MySQL, PHP and HTML5 were used to build the database and interface. The STR locus geno typing and chimeric analysis logic and flow were set up on the basis of STR rules and capillary electrophoresis.

[Analysis of Correlation between Gene Mutation and Age in Patients with MDS and MDS/AML].

Objective: To study the correlation between tumor-associated somatic gene mutation and age in patients with myelodysplastic syndromes (MDS) and acute myeloid leukemia transformed from myelodysplastic syndrome (MDS/AML).

Methods: A total of 111 patients primarily diagnosed as MDS or MDS/AML were selected. Bone marrow samples from patients were collected or bone marrow smears prepared at the initial diagnosis were used for detecting the somatic gene mutations of 58 genes related with hematologic tumors by high-throughput gene sequencing.

The polarization and the fundamental sensitivity of K (Cs)-Rb-He hybrid optical pumping spin exchange relaxation free atomic magnetometers.

The hybrid optical pumping spin exchange relaxation free (SERF) atomic magnetometers can realize ultrahigh sensitivity measurement of magnetic field and inertia. We have studied the Rb polarization of two types of hybrid optical pumping SERF magnetometers based on K-Rb-He and Cs-Rb-He respectively. Then we found that Rb polarization varies with the number density of buffer gas He and quench gas N, pumping rate of pump beam and cell temperature respectively, which will provide an experimental guide for the design of the magnetometer.

Adaptive back-stepping tracking control for rotor shaft tilting of active magnetically suspended momentum wheel.

Two-dimensional gyroscopic torque can be produced by tilting the rotor shaft of the active magnetically suspended momentum wheel. The nonlinear magnetic torque is analyzed and then an adaptive back-stepping tracking method is proposed to deal with the nonlinearity and uncertainty. The nonlinearity of magnetic torque is represented as bounded unknown uncertainty stiffness, and an adaptive law is proposed to estimate the stiffness.

Advances in atomic gyroscopes: a view from inertial navigation applications.

With the rapid development of modern physics, atomic gyroscopes have been demonstrated in recent years. There are two types of atomic gyroscope. The Atomic Interferometer Gyroscope (AIG), which utilizes the atomic interferometer to sense rotation, is an ultra-high precision gyroscope; and the Atomic Spin Gyroscope (ASG), which utilizes atomic spin to sense rotation, features high precision, compact size and the possibility to make a chip-scale one.

[Study on the terahertz spectrum of Haojiami].

Haojiami is a very effective drug to treat malaria, and as a result of its unique drug efficacy, it is widely used in the clinical medicine. It was studied experimentally by terahertz (THz) time-domain spectroscopy (THz-TDS), and the characteristic absorption spectra were obtained in the range of 0.2 to 3.
