Objective: The aim of this study was to conduct a systematic evaluation of exercise interventions' effectiveness on antenatal depressive symptoms in pregnant women and to investigate the impact of different intervention factors on the relationship between exercise and antenatal depressive symptoms. Methods: We conducted comprehensive searches in several databases, including PubMed, Embase, Web of Science, Cochrane Library, and others. The search period covered from database inception to May 2023. After thorough screening, a total of 7 papers with 524 subjects were included in the analysis. Results: The meta-analysis revealed that the overall effect size of exercise intervention on antenatal depressive symptoms in pregnant women was SMD = -0.41, with a 95% confidence interval of [-0.78, -0.05], and P = 0.03, indicating a significant improvement in depressive symptoms due to exercise intervention during the antenatal period. However, some degree of heterogeneity was observed among the studies, with I² = 74%, P = 0.0007. Conclusion: The results indicate that exercise interventions significantly contribute to the improvement of antenatal depressive symptoms in pregnant women, as inferred from the combined findings of the studies. Notably, static exercise intervention showed better results than dynamic exercise intervention. Moreover, interventions conducted before 20 weeks' gestation had superior outcomes compared to those conducted after 20 weeks' gestation, and interventions lasting longer than the trimester duration exhibited more favorable effects than shorter interventions. However, to validate these findings and optimise exercise intervention protocols for better antenatal maternal depressive symptom management, larger sample sizes and more comprehensive studies are required, given the observed heterogeneity and potential limitations in the present study.

The experiment was to study the effects of bacterial enzyme cooperative fermented feed on the nutrient apparent digestibility, milk yield, milk composition, and antioxidant index of dairy cows. A total of 160 lactating cows were randomly divided into two groups, with 10 replicates per group and eight cows per replicate. The control group was fed a basal diet, while the experimental group was fed a basal diet supplemented with 10% bacterial enzyme cooperative fermented feed. The preliminary trial lasted for seven days, and the formal trial period was 42 days. The results showed that compared with the control group, the apparent digestibility of crude protein, crude fat, neutral detergent fiber, and acid detergent fiber in the experimental group were significantly increased (P<0.05), milk yield and feed conversion rate were significantly increased (P<0.05), milk protein content was significantly increased (P<0.05), and the number of somatic cells and total bacterial count were significantly decreased (P<0.05); the activity of superoxide dismutase (SOD) and the total antioxidant capacity (T-AOC) were significantly increased (P<0.05), and the content of malondialdehyde (MDA) was significantly reduced (P<0.05). The study indicates that the addition of 10% bacterial enzyme cooperative fermented feed in the diet can improve the nutrient apparent digestibility, milk yield, milk quality, and serum antioxidant capacity in lactating cows.

The aim of the study was to investigate the effect of condensed tannins on growth performance, slaughter performance, meat quality and antioxidant capacity of mutton sheep. A total of 27 Duhan hybrid (Duper sheep x small-tailed Han sheep) ewes were randomly divided into three groups, with nine replicates in each group and one sheep in each replicate. Sheep in control group were fed with a basal diet, sheep in low-dose group and high-dose group were fed with a basal diet supplemented with 39.47 and 78.94 g/kg condensed tannin, respectively. The experiment lasted for 60 d. The results showed that final weight, average daily gain and average daily feed intake in the low-dose group were significantly higher than those in the control group (P<0.05), and the feed to gain ratio was significantly lower than that in the control group (P<0.05). The average daily feed intake of the high-dose group was significantly higher than that of the control group (P<0.05). The GR value and carcass weight in the low-dose group were significantly higher than those in the control group (P<0.05). The pH24h value, cohesiveness and mastication of mutton in the low dose and high-dose groups were significantly higher than those in the control group (P<0.05). The drip loss rate of mutton in the low-dose group was significantly lower than that in the control group (P<0.05), and the cooking loss was significantly higher than that in the control group (P<0.05). The T-AOC, activity of SOD, CAT and GSH-Px in the serum of mutton sheep in the low-dose group were significantly higher than those in the control group (P<0.05), and the content of MDA was significantly lower than that in the control group (P<0.05). The serum CAT activity of the high-dose group was significantly higher than that of the control group (P<0.05). The study indicates that the dietary 39.47 g/kg condensed tannins can improve the growth performance, antioxidant capacity, slaughter performance and meat quality of mutton sheep.

Continuous renal replacement therapy (CRRT) is widely used for treating critically-ill patients in the emergency department in China. Anticoagulant therapy is needed to prevent clotting in the extracorporeal circulation during CRRT. Regional citrate anticoagulation (RCA) has been shown to potentially be safer and more effective and is now recommended as the preferred anticoagulant method for CRRT. However, there is still a lack of unified standards for RCA management in the world, and there are many problems in using this method in clinical practice. The Emergency Medical Doctor Branch of the Chinese Medical Doctor Association (CMDA) organized a panel of domestic emergency medicine experts and international experts of CRRT to discuss RCA-related issues, including the advantages and disadvantages of RCA in CRRT anticoagulation, the principle of RCA, parameter settings for RCA, monitoring of RCA (mainly metabolic acid–base disorders), and special issues during RCA. Based on the latest available research evidence as well as the paneled experts' clinical experience, considering the generalizability, suitability, and potential resource utilization, while also balancing clinical advantages and disadvantages, a total of 16 guideline recommendations were formed from the experts' consensus.
