Di'ao Xinxuekang alleviates non-alcoholic steatohepatitis in mice by up-regulating Nrf2/HO-1 signaling pathway / 中国中药杂志

The present study investigated the therapeutic effect and mechanism of Di'ao Xinxuekang(DXXK) on non-alcoholic steatohepatitis(NASH) in mice. Sixty-five C57 BL/6 J mice were randomly divided into a normal group and an experimental group for model induction with the high-fat diet for 16 weeks. Then the mice in the experimental group were randomly divided into a model group, an atorvastatin group(4 mg·kg~(-1)·d~(-1)), and high-(200 mg·kg~(-1)·d~(-1)), medium-(60 mg·kg~(-1)·d~(-1)), and low-dose(20 mg·kg~(-1)·d~(-1)) DXXK groups, with 10 mice in each group. Drugs were administered by gavage for eight weeks. Serum lipid, liver lipid, serum alanine aminotransferase(ALT), aspartate aminotransferase(AST), malondialdehyde(MDA), superoxide dismutase(SOD), and glutathione reductase(GSH-Px) were determined. Interleukin-1β(IL-1β) and tumor necrosis factor-α(TNF-α) were measured by enzyme-linked immunosorbent assay(ELISA). The liver index was calculated. The liver pathological change and lipid accumulation were observed by HE and oil red O staining. The liver ultrastructure was observed by the transmission electron microscope. The mRNA and protein expression of nuclear factor-erythroid 2 related factor 2(Nrf2) and heme oxygenase-1(HO-1) was detected by real-time fluorescence-based quantitative PCR and Western blot, respectively. The results showed that compared with the normal group, the model group displayed serum lipid and liver lipid metabolism disorders, elevated transaminase, lipid deposition, steatosis, and inflammation, suggesting that the NASH model in mice was properly induced. Compared with the model group, the DXXK groups showed decreased serum lipid, liver lipid, ALT, AST, MDA, IL-1β, and TNF-α, increased SOD and GSH-Px, alleviated hepatic steatosis, ballooning, and inflammation, and up-regulated Nrf2 and HO-1 gene and protein expression. In conclusion, DXXK can significantly alleviate NASH in mice, which is related to the inhibition of oxidative stress and inflammatory damage by up-regulating the Nrf2/HO-1 signaling pathway.

Animal Models of Nonalcoholic Fatty Liver Disease：A Review / 中国实验方剂学杂志

Nonalcoholic fatty liver disease （NAFLD） is a metabolic stress-induced liver injury characterized by excessive lipid accumulation in hepatocytes， which is closely related to insulin resistance and genetic susceptibility. It falls into the category of "liver lump" in traditional Chinese medicine （TCM）. NAFLD affects about 25% of the population worldwide and has become a major burden of the world health care system. However， its exact pathogenesis remains unclear. Conducting the basic research on NAFLD is of great clinical significance and social value. As an important tool for NAFLD research， animal model plays a particularly important role in clarifying the pathophysiological mechanism of NAFLD. In recent years， the modeling methods for NAFLD in China and abroad have been constantly updated， and in particular， certain progress has been made in the duplication of TCM syndrome models. By consulting and sorting out the relevant literature published in recent years in China and abroad， the author summarized the replication methods of NAFLD animal models. This paper reviewed the advantages and disadvantages of models established via dietary induction （high-fat feed， high-fat and high-fructose feed， high-fat and high-cholesterol feed， and methionine choline-deficient feed）， models with genetic defects ［leptin-deficiency （Lepob/Lepob）， autosomal recessive diabetes gene homozygous deficiency （ob/ob）， Alms1 gene （foz/foz） mutation， and FATZO mice］ and exposure to special diets， and models for TCM syndromes （liver depression and spleen deficiency syndrome， phlegm-dampness syndrome， blood stasis syndrome， combined phlegm and stasis syndrome， and qi stagnation and blood stasis syndrome）， in order to provide reference for the preparation of more scientific， reasonable， economical， and convenient animal models of NAFLD， thus laying a foundation for in-depth study of the pathogenesis， prevention， and treatment of NAFLD.

Health self-assessment of the migrant workers received physical examination in Shanghai / 上海预防医学

Objective:To understand the health self-assessment and related influencing factors in the migrant workers who received of physical examination in Shanghai， so as to provide reference for formulating health service policies for migrant workers. Methods:Taking Shanghai "Intelligent Blue Collar" Health Science Popularization Service Station as the investigation site， 8，100 urban workers were surveyed by questionnaire. The questionnaire includes basic information， health self-assessment， basic medical insurance coverage and satisfaction， subjective well-being and so on. Results:There were significant differences between migrant workers and local workers in health self-assessment， two-week disease prevalence rate， and chronic disease prevalence rate（χ2=32.981，P<0.05；χ2=4.554，P<0.05；χ2=86.695，P<0.05）. The differences between migrant workers and local workers were also significant in the basic medical insurance coverage rate and the level of satisfaction （χ2=221.592，P<0.05；χ2=30.950，P<0.05）. There was no significant difference in subjective well-being between these two groups（χ2=8.787，P>0.05）. The health self-assessment of older migrant workers was significantly better than that of new generation migrant workers（β=0.062，P<0.05）， and was significantly worse in female migrant workers than that in male migrant workers（β=-0.120，P<0.05）. The health self-assessment was significantly better in migrant workers with agricultural household registration than that in non-agricultural household registration（β=0.060，P<0.05）. The higher the satisfaction of basic medical insurance，the higher the subjective well-being and the better the health self-assessment（β=0.148，P<0.05；β=0.422，P<0.05）. Conclusion:The health status of migrant workers in Shanghai who received physical examination is better than that of local workers， and the participation rate of basic medical insurance is lower than that of local workers. Age， gender and household registration are the important factors influencing the health self-assessment. Satisfaction with basic medical insurance level and subjective well-being is a significant factor to predict health self-assessment positively . We should further improve the fairness of medical insurance benefits for migrant workers， improve subjective well-being， and ensure the health fairness of the group.

Molecular epidemiology of Listeria monocytogenes isolated from ready-to-eat food in 2017 in China / 中华预防医学杂志

To analyze the molecular characteristics of strains from ready-to eat food in China. A total of 239 strains isolated from ready-to-eat food in 2017, all strains underwent whole-genome sequencing (WGS) , and comparisons uncovered population structure derived from lineages, clonal complex, serogroups, antimicrobial susceptibility and virulence, which were inferred in silico from the WGS data. Core genome multilocus sequence typing was used to subtype isolates. All strains were categorized into three different lineages, lineage Ⅱ was the predominant types in food, and IIa was the main serogroups. CC8, CC101 and CC87 were the first three prevalent CCs among 23 detected CCs, accounting for 49.4%. Only 4.6% (11 isolates) of tested strains harbored antibiotic resistance genes, which were mostly trimethoprim genes (7 isolates, 2.9%). All strains were positive for LIPI-1, and only a part of strains harbored LIPI-3 and LIPI-4, accounting for 13.8% (33 isolates) and 14.2% (34 isolates), respectively. ST619 carried both LIPI-3 and LIPI-4. 51.5% (123 isolates) of strains carried SSI-1, and all CC121 strains harbored SSI-2. Different lineages, serogroups and CCs can be separated obviously through cgMLST analysis, and 24 sublineages were highly concordant with CCs. Ⅱa was the main serogroups in ready-to-eat food isolates in China; CC8, CC101 and CC87 were the prevalent CCs, and CC87 isolates was hypervirulent isolates, cgMLST method can be adopted for prospective foodborne disease surveillance and outbreaks detection.

Application of Neuromodulation Technique in Treatment of Aphasia (review) / 中国康复理论与实践

Aphasia is the most common language communication disorder after stroke, which has a great impact on the work, life and social interaction of patients. The mechanism of brain recovery in aphasia is mainly to restore language function by regulating the synaptic plasticity of the brain and remolding the network of language function areas. Neuromodulation techniques based on brain network remodeling have been shown to be effective at the early and recovery stages of aphasia. Transcranial direct current stimulation (tDCS), transcranial magnetic stimulation (TMS) and mirror neuron therapy (MNT) are neuromodulation techniques that have been developed rapidly in recent years. They can directly or indirectly affect the cerebral cortex by electrical or chemical means, causing cortical excitability changes in the relevant language functional areas, so as to improve the language function of aphasic patients (listening comprehension, picture naming, repetition, daily communication, etc.). tDCS, as a safe, convenient and non-invasive neuro-regulation technology, can regulate the activity of brain neurons through different currents and electrode placement to treat aphasia, and the effect has remained in the follow-up. TMS technology is safe and non-invasive. Through the selection of different frequencies, stimulation sites, it can activate the corresponding cerebral cortex and subcortical axons, and improve the language function of aphasia patients. The damaged language network can be repaired and reshaped by activating mirror neurons, so as to improve the language functions of patients, such as naming, repetition, listening and comprehension. The relationship between mirror neurons and motor, sensation and language can be used as entry point for treatment of aphasia. The application of neuromodulation techniques to neuroelectrophysiology and neuroimaging has become a new direction in treatment of aphasia.

Regulation of extracellular ATP onchlorophyll content and fluorescence characteristics of Angelica sinensis seedlings under drought and low temperature stress / 中国中药杂志

As an important signal molecule, extracellular ATP(eATP) can regulate many physiological and biochemical responses to plant stress. In this study, the regulation of extracellular ATP(eATP) on chlorophyll content and chlorophyll fluorescence parameters of Angelica sinensis seedlings were studied under drought and low temperature stress. The results showed that all the chlorophyll content, the actual photochemical efficiency [Y(Ⅱ)], the electron transfer rate(ETR), the photochemical quenching coefficient(qP and qL) of A. sinensis leaves were significantly decreased under drought and low temperature stress, respectively. At the same time, non-photochemical quenching(NPQ and qN) were also all significantly increased, respectively. The application of eATP alleviated the decrease of chlorophyll content, Y(Ⅱ), ETR, qP and qL of A. sinensis leaves under drought and low temperature stress, and eliminated the increase of qN and NPQ. The results indicated that eATP could effectively increase the open ratio of PSⅡ reaction centers, and improve the electron transfer rate and light energy conversion efficiency of PSⅡ of A. sinensis leaves under drought and low temperature stress. It is beneficial to enhance the chlorophyll synthesis and the adaptability of PSⅡ about A. sinensis seedlings to drought and low temperature stress.

Physiological effects of cadmium stress on Astragalus membranaceus seedlings and alleviative effects of attapulgite clay on cadmium stress / 中国中药杂志

In this study we investigate the effects of cadmium stress on Astragalus membranaceus seedlings and the alleviative effects of attapulgite clay in growth substrate on cadmium stress to A. membranaceus seedlings. The results showed that the Y (Ⅱ) (effective photochemical quantum yield of PSⅡ photosynthetic), qP(photochemical quenching coefficient), ETR(the rate of non-cyclic electrontransport through PSⅡ), and chlorophyll content of the leaves were significantly decreased with the increase of cadmium concentrations, while the cadmium content, non-photochemical quenching(NPQ, qN) of the leaves and cadmium content, MDA content, plasma membrane permeability, and the damage degree of root apical membrane of the roots were significantly increased. Simultaneously, the activities of APX(ascorbate peroxidase), SOD(superoxide dismutase), POD(peroxidase), CAT(catalase), soluble protein content, and soluble sugar content of roots were increased first but then decreased with the increasing cadmium concentration. Under the condition of without Cd stress, the attapulgite clay into the growth substrate did not significantly affect above physiological indexes of leaves, but significantly increased SOD activity and soluble sugar content of roots and decreased the MDA content, damage degree of root apical membrane of roots, while other physiological indexes did not significantly change. Under cadmium stress, the presence of attapulgite clay in the growth substrate significantly alleviated the cadmium-induced decreases Y (Ⅱ), qP, ETR and chlorophyll content of leaves, and the CAT activity, soluble protein content, and soluble sugar content of roots. Under condition with cadmium stress, the presence of attapulgite clay significantly alleviated the cadmium-induced increases of leaves cadmium content, qN and NPQ, and the cadmium content, MDA content, plasma membrane permeability, damage degree of root apical membrane, SOD, POD, and APX activity of the roots. And, the alleviative effects of attapulgite clay on cadmium stress to A. membranaceus roots were more obvious with the increase of cadmium stress time. The above results showed that the addition of attapulgite clay into the growth substrate has certain alleviative effect on the cadmium stress to A. membranaceus seedlings.

SIC algorithm based model updating for near infrared analysis of Salvia miltiorrhiza alcohol extraction process / 中国中药杂志

The near-infrared (NIR) spectroscopy for offline monitoring of alcohol extraction process of Salvia miltiorrhiza was investigated, with high performance liquid chromatography (HPLC) determination of value for reference. The partial least squares method was adopted to establish the tanshinone ⅡA quantitative calibration model, so as to detect extraction process of Salvia miltiorrhiza. Because the differences between batches of raw materials may endanger the robustness of the original model, the simple interval calculation (SIC) was applied in updating the near-infrared quantitative model for traditional Chinese medicine extraction process for the first time, and compared with Random Selection (RS) method. SIC's final updating results showed that root mean square with cross validation (RMSECV), root mean square error of prediction (RMSEP) and residual predictive deviation (RPD) of tanshinone ⅡA were 0.006 8 g•L⁻¹, 0.005 4 g•L⁻¹ and 3.14, respectively; but RS' final updating results showed that RMSECV, RMSEP and RPD were 0.006 4 g•L⁻¹, 0.006 8 g•L⁻¹ and 2.50, respectively. This study suggested that SIC is superior to RS, and provided a research foundation for quality control and monitoring of S. miltiorrhiza extraction process in the future.

The laser-induced breakdown spectroscopy (LIBS) was applied to perform a qualitative elementary analysis on four precious Tibetan medicines, i. e. Renqing Mangjue, Renqing Changjue, 25-herb coral pills and 25-herb pearl pills. The specific spectra of the four Tibetan medicines were established. In the experiment, Nd: YAG and 1 064 nm-baseband pulse laser were adopted to collect the spectra. A laser beam focused on the surface of the samples to generate plasma. Its spectral signal was detected by using spectrograph. Based on the National Institute of Standard and Technology (NIST) database, LIBS spectral lines were indentified. The four Tibetan medicines mainly included Ca, Na, K, Mg and other elements and C-N molecular band. Specifically, Fe was detected in Renqing Changjue and 25-herb pearl pills; heavy mental elements Hg and Cu were shown in Renqing Mangjue and Renqing Changjue; Ag was found in Renqing Changjue. The results demonstrated that LIBS is a reliable and rapid multi-element analysis on the four Tibetan medicines. With Real-time, rapid and nondestructive advantages, LIBS has a wide application prospect in the element analysis on ethnic medicines.
