BACKGROUND: Currently, inhaled glucocorticoid is still the classic treatment for asthma. Adult stem cell transplantation has made significant progress in a variety of diseases, and it also provides new insights into the treatment of asthma. OBJECTIVE: To summarize the recent advances in the treatment of asthma with adipose-derived stem cells and related adult stem cells, and to discuss the therapeutic safety of adipose-derived stem cells and possible research directions in asthma therapy. METHODS: Relevant articles published from 2001 to 2016 were searched in PubMed, CBM, CNKI, and Wanfang databases. The keywords were “(adipose-derived stem cells[All Fields]) OR (adipose stem cells[All Fields]) OR (adipose-derived mesenchymal stem cells[All Fields]) AND (asthma[All Fields])” in English and Chinese, respectively. RESULTS AND CONCLUSION: A total of 125 literatures were initially searched, and finally 54 representative papers were selected. Adipose-derived stem cells may reduce airway inflammation, airway hyperresponsiveness, ease collagen deposition and scar tissue formation, promote neovascularization, and reconstruct damaged airways in the mouse asthma model through immune regulation. It is necessary to understand its treatment mechanism of action deeply and comprehensively and carry out genomic analysis before introduction of adipose-derived stem cells as a conventional clinical treatment. In summary, adipose-derived stem cells may be a therapeutic potential for the treatment of airway allergic inflammatory diseases such as asthma. [ABSTRACT FROM AUTHOR]

Differential evolution ( DE) algorithm has some disadvantages, such as slow convergence speed, low convergence precision and easy to fall into local optimal solution in the early stages of the evolution. The paper proposed an improved adaptive differential evolution (IADE) algorithm by improving the mutation equation of DE and introducing a new control parameters adaption strategy. In the process of the evolution,the control parameters will be dynamically adjusted by comparing individual fitness with average fitness of the parent population. Meanwhile, the paper chose the ten standard functions commonly used for the comparison of optimization algorithm to perform the comparative test of IADE and the other improved DE algorithms, and the experimental results show that IADE algorithm not only can significantly improve the convergence speed and convergence precision, but also has very good robustness, so that IADE algorithm can meet the requirements for the real-time .accuracy and stability of process optimization.

In order to study the fire risk of oil shale dust， an asymmetric model of dust layer ignition under steady-state condition was established by using chemical reaction kinetics， heat transfer and Thomas thermal ignition theory. The minimum ignition temperature of dust layer of 4 oil shale samples from the major producing areas of China was tested. The results showed that the minimum ignition temperature is between 503~613K， and it decreases with the increasing layer thickness. The minimum ignition temperature order of the four samples is as follows: Fushun> Huadian> Longkou> Maoming， which is correlated reciprocally with volatile content. Using the theory model， the activation energy and critical ignition temperature corresponding to different thickness were calculated. It was found that the error between the calculation critical ignition temperature and experimental results is within 10%， which provides a feasible method on theoretical prediction of fire risk in the oil shale production process.

[Objective] The main spoilage microorganisms in postharvest melon were isolated and identified, and the antagonistic strains with the best preservative effect were screened to enrich the antagonistic bacteria resources for postharvest preservation of melon. (Method) In the study, the tissue block separation method was used to isolate the spoilage bacteria in the rotting melon fruit, and the gradient dilution method was used to isolate the antagonistic bacteria from the soil of the melon planting area. The biocontrol bacteria with strong antagonistic effect were screened by the plate confrontation method, and the species were determined by morphological observation, physiological and biochemical determination and biological identification. The effect of antagonistic bacteria on mycelial growth and conidia germination was determined to clarify the control effect of antagonistic bacteria on spoilage bacteria. (Result) In the study, a major pathogen CH-3 was isolated. Through BLAST alignment and phylogenetic analysis of ITS, tef and tub gene sequences, combined with the observation of colony morphological characteristics, the pathogen CH-3 was identified as Fusarium oxysporum. 67 strains of bacteria were isolated from the soil of muskmelon planting area. Three strains of antagonistic bacteria with strong antibacterial activity were obtained by antagonistic test, which were BG-1, BG-2 and BG-3, respectively. BG-2 with better antibacterial effect was selected as the test strain. Combined with physiological and biochemical determi- nation, colony and bacterial morphological characteristics observation and 16S rDNA, gyrB and rpoB gene sequence analysis results, the antagonistic bacteria BG-2 was identified as Bacillus velezensis. The results of pathogenicity test showed that the pathogenic fungus CH-3 was patho- genic to melon. The relative inhibition rates of BG-2 on spore germination and mycelial growth of F. oxysporum CH-3 were 90.00% and 60.11%, respectively. [Conclusion] An antagonistic strain BG-2 with the best antagonistic effect is obtained and identified as B. velezensis. A main spoilage fungus CH-3 of melon is isolated and identified as F. oxysporum. B. velezensis BG-2 has a strong antagonistic effect on F. oxysporum CH-3, and the spoilage fungus CH-3 is pathogenic to melon. The antagonistic bacteria BG-2 can effectively inhibit the spore germination and mycelial growth of F. oxysporum CH-3, and the higher the concentration of antagonistic bacteria, the better the inhibitory effect on spore germination. It has potential application value in postharvest storage and biological preservation of melon. [ABSTRACT FROM AUTHOR]

BACKGROUND: Some studies have shown that the hounsfield units (HU) value based on lumbar CT can be used to screen osteoporosis. At present, the number of patients with pulmonary infection has increased; the number of patients with pulmonary infection and type 2 diabetes is also increasing, which increases the utilization rate of chest CT. OBJECTIVE: To investigate the role of lumbar 1 vertebral body HU value based on chest CT in the screening of type 2 diabetes mellitus osteoporosis. METHODS: The clinical data of 244 patients with type 2 diabetes mellitus treated in the First Affiliated Hospital of Chengdu Medical College from June 2020 to June 2022 were analyzed retrospectively. The bone mineral density was obtained by dual-energy X-ray absorptiometry. According to WHO’s diagnostic criteria for osteoporosis, the subjects were divided into the non-osteoporosis group (n=120) and the osteoporosis group (n=124). The general condition, T value and HU value of lumbar 1 vertebra in chest CT were compared, and the relationship between the HU value and T value of each position was analyzed and the accuracy of type 2 diabetes mellitus osteoporosis was evaluated. RESULTS AND CONCLUSION: (1) There was no significant difference in sex, age, body mass index, glycosylated hemoglobin, mean blood glucose, calcium (Ca), phosphorus (P), time of type 2 diabetes mellitus, history of hypertension and history of hyperlipidemia between the two groups (P > 0.05). (2) The HU value was positively correlated with the lowest T value of the hip (r=0.619, P < 0.01); the HU value was positively correlated with the hip T value (r=0.584, P < 0.01), and the HU value was positively correlated with the femoral neck T value (r=0.641, P < 0.01). When the HU value was 98, the prediction of type 2 diabetes mellitus osteoporosis had good accuracy, and the sensitivity was 70.8%. (3) It is concluded that the HU value of the lumbar 1 vertebra based on chest CT examination is of good value for osteoporosis screening in patients with type 2 diabetes mellitus, and may be an opportunistic and cost-free supplementary screening method for type 2 diabetes mellitus osteoporosis.

Cancer cachexia occurs in a majority of advanced cancer patients. These patients with impaired physical function are unable to tolerance cancer treatment well and have a significantly reduced survival rate. Currently, there is no effective clinical treatment available for cancer cachexia, therefore, it is necessary to clarify the molecular mechanisms of cancer cachexia, moreover, new therapeutic targets for cancer cachexia treatment are urgently needed. Very recent studies suggest that, during cancer cachexia, white adipose tissue undergo a 'browning' process, resulting in increased lipid mobilization and energy expenditure, which may be necessary for the occurrence of cancer cachexia. In this article, we summarize the definition and characteristics of cancer cachexia and adipose tissue 'browning', then, we discuss the new study directions presented in latest research.

In a voting system， each voter makes a preferential list about candidates， thus a large amount of ordered lists are obtained. To get a comprehensive voting result from these lists， an effective lists merging algorithm is required， which can analyze these lists data and output a comprehensive list. A merging algorithm based on credibility is proposed. Through analyzing the data of lists， numerous ranking messages are extracted， then the credibility of them is formulated and measured， with which the final comprehensive list is computed such that those ranking messages with high credibility could play a more influential role in the final ranking result. Experimental results fully indicate that the algorithm proposed can dig out the credibility about ranking information more effectively， thus attaining the merging results more accurately.
