Objective: To analyze the relationship between asthma and nocturia in women based on the National Health and Nutrition Examination Survey (NHANES) database from 2005 to 2018,so as to provide reference for the prevention and treatment of female nocturia. Methods: Female respondents aged ≥20 years with nocturia or asthma were selected from the 2005-2018 NHANES database.Those with both diabetes stroke and obstructive sleep apnea syndrome were excluded.A weighted analysis was conducted using a complex sampling design.The association between asthma and nocturia in women was evaluated with univariate analysis，propensity score matching (PSM)，and multivariate logistic regression models. Results: A total of 14 718 respondents were selected，of whom 1426 (9.7%) were diagnosed with asthma，and 4664 (31.7%) with nocturia.There is a significant correlation between asthma and nocturia (χ =39.846，P<0.01). Age，body mass index (BMI)，smoking and race were also associated with nocturia (P<0.01).Multivariate logistic regression analysis showed that，the age，BMI，smoking，race and asthma were correlated with the risk of nocturia，before PSM matching (P<0.05).To eliminate confounding bias，PSM was applied，and generalized linear mixed model analysis after matching showed that the risk of nocturia remained high in asthma patients (OR=1.540，95% CI：1.320-1.800，P<0.01). Conclusion: Asthma is associated with nocturia in women，indicating that it may be an important risk factor for female nocturia.

ObjectiveTo investigate the correlation between the color， odor and volatile components of Paeoniae Radix Alba（PRA） and its processed products， and to examine the effects of different processing methods on the odor and color formation of PRA. MethodThe odor and chromaticity information of PRA， honey chaff-fried PRA and honey bran-fried PRA were identified by electronic nose and colorimeter， and the volatile components in the different processed products of PRA were identified and relatively quantified by headspace gas chromatography-mass spectrometry（HS-GC-MS）， and analyzed using principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA）， then the differential key flavor components among the three were screened according to the principles of variable importance in the projection（VIP） value>1 and relative odor activity value（ROAV）≥1. Pearson correlation analysis was used to investigate the association between the differential flavor components and the colorimetric values and electronic nose sensors， respectively. ResultAfter being fried with honey chaff and honey bran， the lightness value（L^*） of PRA decreased， and red-green value（a^*） and yellow-blue value（b^*） increased significantly（P<0.05， P<0.01）. The odor differences were mainly reflected in the S1， S2， S4， S5， S6， S8 and S11 sensors， and the results of PCA of the electronic nose indicated that the odor differences among PRA， honey chaff-fried PRA and honey bran-fried PRA were obvious， among which the overall odor intensity of honey bran-fried PRA was higher than that of honey chaff-fried PRA. A total of 47 volatile components were identified from PRA and its processed products， including 21 for PRA， 36 for honey chaff-fried PRA， and 37 for honey bran-fried PRA. Odor analysis revealed that 12， 24 and 22 volatile components may be the key flavor components in PRA， honey chaff-fried PRA and honey bran-fried PRA， respectively. Correlation analysis showed that the L^* of the decoction pieces was negatively correlated with the content of the Maillard reaction products， the a^* and b^* were positively correlated with the content of the Maillard reaction products， the S1 and S8 sensors were negatively correlated with the content of the Maillard reaction products， and the S2， S4， S5， S6 and S11 sensors were positively correlated with the Maillard reaction products. ConclusionThe color of PRA is deepened after being stir-fried with honey chaff and honey bran， and 5-hydroxymethylfurfural， furfural and other components are generated at the same time， which is in line with the theory of burning aroma strengthens the spleen of stir-fried with honey chaff and honey bran. Honey bran-fried PRA has a stronger Maillard reaction than honey chaff-fried PRA， which makes honey bran-fried PRA with a burnt flavor and a dark yellow color， while honey chaff-fried PRA has a sweet flavor and a bright yellow color.

OBJECTIVE To investigate the efficacy and safety of piperacillin-tazobactam in the treatment of complicated urinary tract infection （cUTI） in adults. METHODS Retrospective analysis was performed on the data of 352 cUTI adult patients in our hospital from January 1， 2021 to December 31， 2023. All patients received piperacillin-tazobactam. The detection of pathogens in patients， the clinical efficacy and microbial clearance rate after treatment， the occurrence of adverse drug reactions and treatment cost were observed in all patients. RESULTS Of the 352 patients， pathogen culture results of 54 patients were detected， mainly Escherichia coli producing extended-spectrum beta-lactamases. The clinical effective rate was 94.3%， the microbial clearance rate was 81.5%， and the incidence of adverse reactions was 1.4%. The percentage of male effective patients in urinary surgery department was significantly higher than invalid patients， while the proportion of transplant treatment and the proportion of patients with concomitant kidney transplantation were significantly lower than invalid patients （P＜0.05）. There was no significant difference in clinical effective rate between the two groups after those patients were divided into target treatment group and empirical treatment group according to the sensitivity of pathogen to piperacillin-tazobactam （P＝0.902 5）. CONCLUSIONS Piperacillin-tazobactam is effective and safe in the treatment of cUTI.

As a serious cardiovascular disease, atherosclerosis (AS) causes chronic inflammation and oxidative stress in the body and poses a threat to human health. Lipoprotein-associated phospholipase A2 (Lp-PLA2) is a member of the phospholipase A2 (PLA2) family, and its elevated levels have been shown to contribute to AS. Lp-PLA2 is closely related to a variety of lipoproteins, and its role in promoting inflammatory responses and oxidative stress in AS is mainly achieved by hydrolyzing oxidized phosphatidylcholine (oxPC) to produce lysophosphatidylcholine (lysoPC). Moreover, macrophage apoptosis within plaque is promoted by localized Lp-PLA2 which also promotes plaque instability. This paper reviews those researches of Chinese medicine in treating AS via reducing Lp-PLA2 levels to guide future experimental studies and clinical applications related to AS.

Nonalcoholic fatty liver disease (NAFLD) does great harm to human health, and the incidence is increasing year by year. The liver serves an important role in lipid metabolism. Hepatic steatosis develops as a consequence of lipid metabolic dysregulation, namely the imbalance among fatty acid uptake, de novo lipogenesis (DNL), fatty acid oxidation (FAO) and very low density lipoprotein-mediated lipid export. With diverse health-promoting effects, exercise is a cheap and effective intervention for the prevention and treatment of NAFLD. Amelioration of impaired lipid metabolism acts as an important mechanism by which exercise protects against NAFLD. However, how exercise ameliorates lipid metabolic dysregulation is still unclear. Skeletal muscle is not only a vital organ of motion, but also has an endocrine function, it secretes numerous myokines which mediates exercise-induced benefits on our body. Irisin is a small peptide derived from proteolytic cleavage of fibronectin type III domain containing protein 5 (FNDC5). As a myokine, its production is regulated by exercise and it play an important role in exercise-induced protection against obesity-related chronic diseases, such as NAFLD. A growing body of research has demonstrated that Irisin ameliorates lipid metabolic dysregulation in NAFLD. Irisin mediated inhibition of hepatic DNL and FAO has been reported. However, the effect of Irisin on fatty acid uptake and lipid export is still unknown. In the present review, we summarized the researches focusing on how exercise regulated Irisin production and the effect of Irisin on lipid metabolism on NAFLD. To clarify the above problems will help us to better understand the role of Irisin on exercise-mediated protection against NAFLD.

Analyze the changes in phenolic components and gene expression profiles of Tetrastigma hemsleyanum leaves with supplemental blue light, and screen differentially expressed genes related to phenolic metabolism, providing a basis for improving the quality of T. hemsleyanum leaves. Using the leaves of T. hemsleyanum under supplemental blue light and visible light as research materials, the content of phenolic components such as neochlorogenic acid, chlorogenic acid, and 3-O-coumaroyl quinic acid was significantly increased by supplemental blue light. A total of 102 949 unigenes were obtained from the transcriptome, including 14 564 differentially expressed unigenes. They can be divided into 52 subclasses by gene ontology (GO) function, kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment analysis showed that these differentially expressed unigenes were significantly enriched in phenolic metabolic pathways such as phenylpropane biosynthesis, flavonoid biosynthesis and isoflavone biosynthesis. A total of 63 differentially expressed unigenes were identified in the pathways related to the biosynthesis of phenolic cpmponents, including 19 key enzymes such as phenylalanine ammonia-lyase (PAL), cinnamyl-alcohol dehydrogenase (CAD), flavonol synthase (FLS), and so on. This study greatly enriched the genetic data information of T. hemsleyanum and laid a foundation for analyzing the mechanism of blue light promoting the biosynthesis of phenols and molecular breeding of T. hemsleyanum.

Amorphous solid dispersion (ASD) is one of the most effective formulation approaches to enhance the water solubility and oral bioavailability of poorly water-soluble drugs. However, maintenance of physical stability of amorphous drug is one of the main challenges in the development of ASD. Crystallization is a process of nucleation and crystal growth. The nucleation is the key factor that influences the physical stability of the ASD. However, a theoretical framework to describe the way to inhibit the nucleation of amorphous drug is not yet available. We reviewed the methods and theories of nucleation for amorphous drug. Meanwhile, we also summarized the research progress on the mechanism of additives influence on nucleation and environmental factors on nucleation. This review aims to enhance the better understanding mechanism of nucleation of amorphous drug and controlling over the crystal nucleation during the ASD formulation development.
