为研究大豆压榨过程中压榨特性的变化，以大豆为原料，探究了压榨时间、填料高度和压榨次数对残油率、压缩比、孔隙度、渗透率、微观结构的影响。结果表明：随着压榨时间的延长，大豆饼残油率先快速降低后趋于平缓；随着填料高度的增加，大豆饼残油率增加，压缩比减小，孔隙度增加，渗透率增加;二次压榨后大豆饼残油率降低，压缩比增加，孔隙度降低，渗透率降低；微观结构分析表明，随着填料高度的增加，细胞破碎率降低，更多的油脂残留在细胞内。因此，在实际生产中要合理控制压榨时间、填料高度和压榨次数来提高压榨效率。 In order to study the change of pressing characteristics during soybean pressing, the effects of pressing time, filler height and pressing times on residual oil rate, compression ratio, porosity, permeability and microstructure were investigated using soybean as raw material. The results showed that with the prolonging of the pressing time, the residual oil rate of soybean cake firstly decreased rapidly and then tended to be flat. With the increase of filler height, the residual oil rate of soybean cake increased, the compression ratio decreased, the porosity increased, and the permeability increased. After the secondary pressing, the residual oil rate of soybean cake decreased, the compression ratio increased, the porosity decreased, and the permeability decreased. Microstructure analysis showed that when the filler height increased, the cell fragmentation rate decreased and more oil remained within the cell. Therefore, in actual production, the pressing time, filler height and pressing times should be reasonably controlled to improve the pressing efficiency.

Objective To investigate the effect of butylphthalide on cognitive dysfunction after the stroke caused by cerebral small vessel disease and its effect on cerebral blood perfusion. Methods　84 patients with the cognitive impairment after the stroke caused by small vessel disease were retrospectively selected from the Neurology Department of Shijiazhuang People’s Hospital from March 2019 to March 2021. According to the different treatment methods, they were divided into the control group (basic treatment) and the study group (basic treatment+butylphthalide treatment), with 42 patients in each group. Cognitive function, daily living ability, neurological function deficits, and changes in cerebral blood flow perfusion were observed. Results After 3 months of treatment，MMSE and Barthel index scores increased and NIHSS scores decreased in the two groups (P < 0.05). After the treatment，MMSE and Barthel index scores in the study group were higher than those in the control group (P < 0.05). The mean passage time of patients in the two groups decreased，and the CEREBRAL blood flow and blood flow velocity increased. In comparison with the results between the two groups，the mean passage time of patients in the study group was lower than that of the control group after the treatment，while the cerebral blood flow and blood flow velocity were significantly higher than that of the control group (P < 0.05). Conclusion Butylphthalide can improve the cerebral blood flow perfusion and promote the recovery of patients’ cognitive function and daily living ability in the treatment of cognitive dysfunction after the stroke caused by cerebral small vascular disease.

Gut microbes play a crucial role in maintaining host health and metabolism, there is a growing body of research on the positive effect on host. At present, the correlation between intestinal microbes and intestinal health, glucose and lipid metabolism and diseases has been confirmed in most livestock and poultry, but the interaction between porcine intestinal microbes and host metabolism is still unclear. The paper expounds the influencing factors of intestinal microorganisms from the aspects of physiological stage, intestinal environment and dietary factors of pigs, summarizes the mechanism of intestinal microorganisms and their metabolites, such as short-chain fatty acids, bile acids, vitamins, inindoles and intestinal health of pigs, discusses the effect of adding probiotics to regulate intestinal microorganisms on pig breeding, to provide reference for pig breeding.

The spatial and temporal distribution of the oceanic boundary layer height is determined by wavelet covariance transform method using COSMIC and ERA-Interim refractive index data independently, then the difference between results of the two datasets is comparatively analyzed. The results show that a roughly same spatial pattern of not completely symmetrical distribution of the boundary layer height along the equator is observed for the inversion results of the two datasets. As for the seasonal and monthly variations, the oceanic boundary layer is relatively high in summer. Though no obvious diurnal variation is observed, it should be noted that the diurnal variation of boundary layer height from ERA-Interim data is more consistent with that of solar radiation. The comparison shows that the inversion results of COSMIC data are about 500-1 000 meters higher than those of ERA-Interim data, and the difference is greater in high latitudes than in low latitudes and smaller in summer than in winter.

Objective: To investigate the predictive value of preoperative prognostic nutritional index (PNI) combined with serum C-X-C motif chemokine ligand 5 (CXCL5) and chitinase-3-like protein 1 (YKL-40) in patients with non-muscular invasive bladder cancer (NMIBC) for recurrence after transurethral resection of bladder tumor (TUR-BT). Methods: A total of 109 patients with NMIBC who were treated with TUR-BT from January 2019 to January 2021 in Cancer Hospital Affiliated to Xinjiang Medical University were selected, and they were divided into recurrence group (n=32) and non-recurrence group (n=77) according to whether there was recurrence after TUR-BT. The clinical data, preoperative PNI, CXCL5 and YKL-40 levels of the two groups were compared. Univariate and multivariate Logistic regression were used to analyze the influencing factors of recurrence after TUR-BT in patients with NMIBC. Receiver operating characteristic (ROC) curve was used to analyze the predictive value of preoperative PNI and serum CXCL5 and YKL-40 levels for recurrence after TUR-BT in patients with NMIBC. Results: After 3 years of follow-up, 32 of 109 patients with NMIBC had recurrence after TUR-BT, the recurrence rate was 29.36%. Multiple tumors, tumors T1 stage, low differentiation ratio and serum CXCL5 and YKL-40 levels in the recurrence group were higher than those in the non-recurrence group, while albumin, lymphocyte count and preoperative PNI levels were lower than those in the non-recurrence group (P＜0.05). Multivariate Logistic regression analysis showed that multiple tumors, tumors T1 stage, low differentiation tumors, increased serum CXCL5 and increased YKL-40 were independent risk factors for recurrence after TUR-BT in patients with NMIBC, while increased preoperative PNI was independent protective factor (P＜0.05). ROC curve analysis showed that preoperative PNI and serum CXCL5 and YKL-40 levels were 0.781, 0.792, 0.780 and 0.955 respectively for predicting recurrence after TUR-BT in patients with NMIBC. The sensitivity was 78.12%, 53.13%, 84.37%, 96.87%, and the specificity was 74.03%, 97.40%, 59.74%, 79.22%, respectively. Preoperative PNI combined with serum CXCL5 and YKL-40 levels predicted the AUC of recurrence after TUR-BT in patients with NMIBC was greater than that predicted by the three alone (P＜0.05). Conclusion: The increased serum CXCL5 and YKL-40 levels are independent risk factors for recurrence after TUR-BT in patients with NMIBC, and increased preoperative PNI is an independent protective factor. Combined detection of the three has a high predictive value for recurrence after TUR-BT in patients with NMIBC. [ABSTRACT FROM AUTHOR]

Sarcopenia is a common disease and frequently occurring disease in the elderly. The main manifestations of sarcopenia are loss of muscle mass, strength and function, which can increase the risk of falls and fractures. With the aggravation of aging society, sarcopenia brings more and more serious problems. Exploring and clarifying the pathogenesis of sarcopenia has become a current research focus. At present, the modeling of sarcopenia has both advantages and disadvantages, An animal model with short modeling time, low cost and a high degree of consistency with human sarcopenia is a key step in the research. Therefore, the domestic and foreign literature in recent years was reviewed to summarize and discuss the research progress of sarcopenia modeling method, in order to provide reference for sarcopenia modeling.
