ABSTRACT
BACKGROUND: Folic acid and vitamin B12 (FV), being B vitamins, not only facilitate the remethylation of homocysteine (Hcy) but also contribute to embryonic development. This study aimed to assess the impact of FV supplementation during late pregnancy on sows' reproductive performance, amino acid metabolism, placental angiogenesis, and related parameters. Twenty primiparous sows at day 60 of gestation were randomly allocated to two groups: a basal diet (CON) group and a group receiving a basal diet supplemented with folic acid at 20 ppm and vitamin B12 at 125 ppb. RESULTS: The findings revealed that dietary FV supplementation significantly reduced the incidence of intrauterine growth retardation compared to the CON group (P < 0.05). Furthermore, it led to a decrease in the Hcy levels in umbilical cord serum (P < 0.05) and activation of the placental mechanistic target of rapamycin complex 1 (mTORC1) signaling pathway (P < 0.05). Additionally, FV supplementation lowered placental malondialdehyde levels (P < 0.05) and increased the expression of placental thioredoxin (P = 0.05). Moreover, maternal FV supplementation notably elevated placental vascular density (P < 0.05) and the expression of sodium-coupled neutral amino acid transporter 2 (SNAT2) (P < 0.05), as well as amino acid concentrations in umbilical cord blood (P < 0.05). CONCLUSION: Maternal FV supplementation during medium to late gestation reduced Hcy levels in umbilical cord blood and positively impacted fetal development. This improvement was closely associated with increased placental antioxidant capacity and vascular density, as well as activation of the placental mTORC1-SNAT2 signaling pathway. © 2023 Society of Chemical Industry.

Piglet survival is a major challenge in the first few days postpartum and interventions during this period may improve survival and growth. This study investigated the effects of palmitoleic acid (C16:1n-7; PA) supplementation on growth performance, body temperature, fatty acid (FA), and energy metabolism in milk-replacer-fed piglets. Forty-eight piglets were stratified by body weight and randomly assigned to one of four dietary treatments (0%, 1%, 2%, and 3% PA supplementation as a percent of milk replacer) and given the diet through an orogastric tube. They were fed dietary treatments every 2 h for 4 d in the first week postpartum and all were sacrificed at the end of the experiment. The piglets were weighed daily, and half in each dietary treatment group, the same piglets each day, were exposed daily to a lower temperature for 2 h. Plasma samples were collected immediately before sacrifice for analyses of FA and other plasma metabolites. The weight of organs and empty body weight were determined after sacrifice. Liver and semimembranosus muscle tissue samples were collected and analyzed for FA content. Contents of C16:1n-7 and C18:1n-7 in both plasma and liver (Pâ <â 0.001), and C16:1n-7 in semimembranosus muscle (Pâ <â 0.001) increased linearly as PA supplementation increased. Most plasma FA levels (except C16:1n-7, C16:1n-9, and C22:5n-3) were lower in piglets exposed to lower temperatures than those that were not. Plasma glucose, triglycerides, and lactate dehydrogenase levels increased linearly with PA supplementation (Pâ <â 0.001). Piglets' average daily gain, liver glycogen pool, liver weight, and gallbladder weight increased linearly (Pâ <â 0.05, Pâ <â 0.01, Pâ <â 0.05, and Pâ <â 0.001, respectively), but lung weight, liver nitrogen content, and body temperature drop decreased linearly (Pâ <â 0.01, Pâ <â 0.001, and Pâ <â 0.05, respectively) with PA supplementation. Piglets exposed to low temperature had greater liver nitrogen (Pâ <â 0.05) and lactate dehydrogenase (Pâ <â 0.001) contents but had lower liver weight (Pâ <â 0.01) and plasma lactate concentration (Pâ <â 0.05) than those that were not. In conclusion, this study demonstrated the importance of PA on the growth performance of the piglets by increasing their average daily gain and decreasing a drop in body temperature upon cold exposure, most likely due to a modified energy metabolism.
Reducing piglet mortality in the early days after birth is a significant challenge in the modern pig industry. The focus on achieving larger litter sizes has had a negative impact on piglets' birth weight and their intake of colostrum. Additionally, piglets are born without easily oxidizable brown adipose tissue and have limited body reserves, making them more vulnerable to death due to their lower capacity for thermogenesis. Therefore, it is important to explore dietary strategies that can enhance piglets' thermogenesis capacity. In this study, the role of palmitoleic acid supplementation was investigated in a dose-response design to determine its impact on growth performance, fatty acid composition, and energy metabolism of milk-replacer-fed piglets during their first week of life. The results revealed a linear increase in the average daily gain of the piglets, liver weight, and liver glycogen content with increasing palmitoleic acid supplementation. Moreover, increased palmitoleic acid supplementation was associated with a drop in body temperature when piglets were exposed to a lower temperature during the experimental period. Altogether, the study indicated that palmitoleic acid has a sparing effect on glycogen reserves and that a greater proportion of energy utilized by the piglets to maintain their body temperature was derived from the oxidation of fatty acids. The results indicated a promising approach to improve piglet survival and growth through dietary modifications of fatty acids in the diet.

This study was conducted to investigate the effects of dietary multi-enzyme (multi-carbohydrase and phytase complex, MCPC) supplementation on digestibility, growth performance, bone mineralization, and carcass yield and traits in growing-finishing pigs fed diets with adequate or deficient net energy (NE), amino acids (AA), calcium (Ca) and phosphorus (P) levels. A total of 576 crossbred [Duroc × (Landrace × Yorkshire)] barrows (~25 kg) were fed one of the six diets till live weight approached 130 kg. Basal diets included a positive control (PC), negative control 1 (NC1) and 2 (NC2), while another three diets were prepared by adding MCPC to the three basal diets. The final body weight was lower (p < 0.05) in NC2 than in NC1 and PC treatments, while overall feed intake and feed-gain ratio were higher (p < 0.05) in NC1 and NC2 than in PC treatment. The NC2 treatment showed lower (p < 0.05) carcass weight but higher (p < 0.05) lean meat percentage than the PC treatment. The apparent ileal digestibility (AID) of gross energy (GE), crude protein (CP) and AA was decreased (p < 0.05) or tended (p < 0.10) to decrease in NC1 and/or NC2 diets compared with a PC diet. MCPC supplementation improved (p < 0.05) AID of Ca, P and AA (Lys, Leu, Val, Phe, Gly, Tyr and Pro), apparent total-tract digestibility (ATTD) of GE, CP, bone strength, Ca, and P retention. In conclusion, MCPC supplementation improved nutrient digestibility, bone mineralization, and growth performance of fattening pigs, regardless of the nutritional level of the basal diet.
ABSTRACT
Selenium (Se) is an essential trace element for the body. Various organs of the body, including the intestine, are affected by its deficiency. Se deficiency can induce oxidative stress and inflammatory responses in the intestine. It can also increase intestinal permeability and decrease intestinal immune function in mammals. However, the detailed studies, conducted on the intestinal molecular mechanisms of Se deficiency-induced injury in poultry, are limited. This study explored the adverse effects of Se deficiency on intestinal permeability and its mechanism. A Se-deficient chicken model was established, and the morphological changes in the chicken duodenum tissues were observed using a light microscope and transmission electron microscope (TEM). Western blotting, qRT-PCR, and other methods were used to detect the expression levels of selenoproteins, oxidative stress indicators, inflammatory factors, tight junction (TJ) proteins, antimicrobial peptides, and other related indicators in intestinal tissues. The results showed that Se deficiency could decrease the expression levels of selenoproteins and antioxidant capacity, activate the nuclear factor kappa-B (NF-κB) pathway, cause inflammation, and decrease the expression levels of TJ proteins and antimicrobial peptides in the duodenum tissues. The study also demonstrated that Se deficiency could increase intestinal permeability and decrease antimicrobial peptides via reactive oxygen species (ROS)/NF-κB. This study provided a theoretical basis for the scientific prevention and control of Se deficiency in poultry. Se deficiency decreased the expression levels of selenoproteins and increased ROS levels to activate the NF-κB pathway, resulting in the production of pro-inflammatory cytokines, reducing the expression levels of TJ protein, and weakening the expression of antimicrobial peptides, which contributed to the higher intestinal permeability. Oxidative stress weakened the expression of antimicrobial peptides.

Traditional Chinese medicine(TCM) has a long history and abundant experience in external therapy, which marks human wisdom. In the early history of human, people found that fumigation, coating, and sticking of some tree branches and herb stems can help alleviate scabies and remove parasites in productive labor, which indicates the emergence of external therapy. Pathogen usually enters the body through the surface, so external therapy can be used to treat the disease. External therapy is among the major characteristic of surgery of TCM. As one of the external therapies in TCM, external application to acupoints smooths the zang-fu organs through meridians and collaterals, thereby harmonizing yin and yang. This therapy emerged in the early society, formed the Spring and Autumn Period and the Warring States Period, improved in the Song and Ming dynasties, and matured in the Qing dynasty. With the efforts of experts in history, it has had a mature theory. According to modern research, it can avoid the first-pass effect of liver and the gastrointestinal irritation and improve the bioavailability of Chinese medicine. Based on the effect of Chinese medicine and the theory of meridian and collateral, it can stimulate the acupoints, exert regulatory effect on acupoints, and give full play to the efficacy of TCM and the interaction of the two. Thereby, it can regulate qi and blood and balance yin and yang, thus being widely used in the treatment of diseases. In this paper, the use of external application to acupoints, the effect on skin immunity, the regulation of neuro-inflammatory mechanism, the relationship between acupoint application and human circulation network, and the development of its dosage form were summarized through literature review. On this basis, this study is expected to lay a foundation for further research.

ObjectiveTo conduct a visualized analysis of the research related to the use of brain-computer interface technology for stroke rehabilitation in the past ten years, and identify and predict the hot spots and hot trends in order to promote the further development of this field. MethodsThe Web of Science Core Collection database was searched for literature related to brain-computer interface technology for stroke rehabilitation from January, 2011 to October, 2022. CiteSpace 5.8.R3 was used to analyze the number of publications, countries, institutions, authors, keywords, co-citations, and grant support. Results and ConclusionA total of 592 papers were included, and the annual number of publications in this field of research showed a rapid growth trend, and the research enthusiasm continued to increase. The United States was in the leading position in this field, with the highest number of cooperative publications and the highest intermediary centrality; China had certain advantages in this field, but still needed to strengthen the exchange and cooperation with other countries/regions. Foreign institutions and authors had formed a network of close cooperative relationships, and formed a high-impact team represented by Niels Birbaumer, Cuntai Guan, Kai Keng Ang, etc.; there were poor cooperative relationships among domestic authors and institutions, and there were geographical restrictions and lack of high-impact academic groups. The keywords "motor imagery" and "recovery" formed ten major clusters and 15 prominent words with high variation rates, showing a trend of diversification in research directions. The study of the efficacy of upper limb motor rehabilitation and central mechanisms has been the hot topics in this field and will continue for some time in the future; the use of lower limb brain-computer interface systems for improving foot drop, gait and balance in stroke patients and the application of multimodal brain-computer interfaces will probably become a hot topic in the future. Finally, the use of brain-computer interface-guided neurofeedback training for cognitive and language rehabilitation in stroke also needs attention.
ABSTRACT
In recent years, the frequency of corruption incidents in public hospitals in China has increased, and it is particularly important to strengthen the construction of hospital incorrupt politics. Based on the traditional chinese medical theory of preventing diseases, the author deeply discusse the prevention and control strategies in high-risk areas of public hospitals incorrupt from 3 aspects: prevention before disease onset, prevention of disease from exacerbating and prevention of recovery from relapse. Based on the common problems found in the political inspection of Beijing municipal health system and large-scale hospitals in the latest years, an incorrupt government risks list of high-risk areas in hospital had been sorted out; A tertiary hospital and its 4 entrusted hospitals were selected to conduct self-inspection on the key links of important power activities and authority behaviors in accordance with the incorrupt government risks list, and putting forward targeted supervision strategies for these problems. Since the implementation of supervision strategy for high-risk areas in the tertariy hospital and its 4 entrusted hospitals in May 2021, the number of letters and visits in the 5 aspects of medicine procurement, equipment procurement, consumables and reagents procurement, engineering construction and logistics service procurement were significantly reduced. Based on the traditional chinese medical theory of preventing diseases, the supervision strategy in high-risk areas could effectively improve the pertinence, operability and effectiveness of discipline inspection and supervision in hospital, and provide a reference for the construction of incorrupt government in public hospitals.
ABSTRACT
Particle design, based on the concept of "quality by design", combines the elements of microbiology, formulation science, heat and mass transfer, solid state physics, powder science, and nanotechnology. It is widely used to develop particles with excellent functional properties. Without affecting the active ingredients, the modification technology of traditional Chinese medicine (TCM) powder based on particle design theory, could improve the flowability, tabletability, disintegration and dissolution behavior, hygroscopicity, wettability, and other functional properties at the physical structure level. This greatly promotes the development of solid preparations of TCM. The present review aims to summarize and discuss the research progress of powder modification of TCM from the perspective of the theory of particle design, powder modification technology, equipment used for powder modification, application in TCM and modification mechanism mainly based on researches published in recent ten years. This review could provide ideas and theory basis for the development of particle design.

This study was conducted to investigate the effects of spray-dried porcine plasma protein (SDPP) or spray-dried chicken plasma protein (SDCP) supplementation in diets without the inclusion of antibiotics and zinc oxide (ZnO) on growth performance, fecal score, and fecal microbiota in early-weaned piglets. A total of 192 healthy weaning piglets (Duroc × Landrace × Yorkshire, 21 d old) were blocked by BW (6.53 ± 0.60 kg) and randomly assigned to 4 dietary treatments: negative control (NC, basal diet), positive control (PC), basal diet + ZnO at 2 g/kg and antibiotics at 0.8 g/kg), SDPP (containing 5% SDPP), and SDCP (containing 5% SDCP). The experiment lasted 14 d. The SDPP group had higher (P < 0.05) final BW, average daily gain and average daily feed intake than the NC and SDCP groups. The percentage of piglets with fecal scores at 2 or ≥2 was higher (P < 0.05) in the NC and SDCP groups than in the PC group. A decreased (P < 0.05) bacterial alpha diversity and Bacteroidetes abundance, but increased (P < 0.05) Firmicutes abundance were observed in the PC and SDPP groups when compared to the NC group. The relative abundance of Lactobacillus was higher (P < 0.05) in the SDPP than in the SDCP group, and that of Streptococcus was higher (P < 0.01) in the PC and SDPP groups than in the NC group. The PC group also had higher (P < 0.01) Faecalibacterium abundance than the NC and SDCP groups. Additionally, the SDCP group had higher (P < 0.05) serum urea nitrogen than those fed other diets, and lower (P < 0.10) short-chain fatty acids to branched-chain fatty acids ratio than the PC and SDPP groups. Overall, SDPP was a promising animal protein for piglets in increasing feed intake, modifying gut microbiota profile, reducing gut protein fermentation and alleviating diarrhea frequency, thus promoting growth performance, under the conditions with limited in-feed utilization of antibiotics and ZnO.
ABSTRACT
Traditional Chinese medicine (TCM) preparations have made tremendous progresses in modernization, whereas there exist relatively few researches pertaining to preparation structures. As demonstrated by the theory and practice of structure pharmaceutics, the structure properties of dosage forms have significant influences on the quality and efficacy of drugs, which might offer reference for the research and development of TCM dosage forms. With the application of synchrotron radiation X-ray micro-computed tomography (SR-μCT) and other novel technologies in recent years, researches in structure pharmaceutics have made huge advancement, which provide reference and methodology basis for the study of TCM preparations. The article generalized and summarized the recent progresses and methods in the structure researches of pharmaceutics and TCM preparations, and further explored the significance of the researches of structure of TCM preparations. It is expected to provide the basis for the dosage form design, production process improvement, and quality evaluation of TCM and promote the modernization of TCM preparations.

ABSTRACT
PURPOSE: We compared the efficacies of intravitreal ranibizumab (IVR) and intravitreal conbercept (IVC) as the adjuvant pretreatments for vitrectomy with silicone oil infusion for tractional retinal detachment (TRD) secondary to proliferative diabetic retinopathy. METHODS: This retrospective study comprised 74 patients (79 eyes) who underwent vitrectomy with silicone oil tamponade for diabetic TRD. They received IVC (37 eyes) or IVR (42 eyes) at standard doses 3-5 days preoperatively and were followed up for â¼6 months. Anatomic success rate, intra- and postoperative complications, and visual outcomes were compared between both groups. RESULTS: Initial (IVC vs. IVR: 97% vs. 98%) and final anatomic success rates (100% in each group) and mean visual acuity changes were not significantly different (P = 0.46). Intraoperative complications [iatrogenic retinal breaks (P = 0.58) and intraoperative bleeding (P = 0.66)], postoperative complications [fibrin formation (P = 0.51), postoperative preretinal bleeding (P = 0.88), progressing or persistent neovascular glaucoma (P = 0.63), progressive fibrovascular proliferation (P = 0.93), and recurrent retinal detachment (P = 0.93)], and surgical variables [surgical time (P = 0.53)] were similar between both groups. CONCLUSIONS: Conbercept and ranibizumab are equally effective surgical adjuvants for vitrectomy with silicone oil infusion in patients with diabetic TRD.

OBJECTIVE@#To evaluate the effect of tai chi exercise on cardiac and static lung function for older community-dwelling adults at risk of ischemic stroke.@*METHODS@#A total of 170 older community-dwelling adults (aged 55-75 years old) at risk of ischemic stroke were allocated to either tai chi training group (85 cases, five 60-min sessions of tai chi training per week for 12 weeks) or control group (85 cases, usual pbysical activity for 12 weeks) using a computer-generated randomization. The echocardiographic parameters of cardiac structure, cardiac function and static lung function were measured at baseline, after 12 weeks of intervention and additional 12-week follow-up period by a blinded professional staffmember using a color Doppler ultrasound imaging device or a cardiopulmonary function instrument. The t test and linear mixed model based on the intentionto-treat analysis principle was used to calculate the effect. The adverse effect was observed.@*RESULTS@#Most of echocardiographic parameters on the cardiac structure, cardiac function and static lung function between the tai chi group and control group did not have a significant difference either post 12-week intervention or additional 12-week follow-up period. Only three parameters involving in right ventricular diameter (P=0.024), main pulmonary artery diameter (P=0.002) and vital capacity maximum (P=0.036) were beneficial to be improved in the tai chi group compared to the control group by the analysis of mixed linear model. No adverse effects were found during the intervention period.@*CONCLUSION@#The 12-week tai chi exercise did not have an obvious beneficial effect on cardiac structure, cardiac function and static lung function in older community-dwelling adults at risk of ischemic stroke. The study with a longer duration of intervention should be necessary. (Trial registration No. ChiCTR-TRC-13003601).
ABSTRACT
The aim of this study was to develop and validate the large intestine dampness-heat syndrome questionnaire (LIDHSQ) for patients with ulcerative colitis (UC). The domains and items of the LIDHSQ were developed according to standard procedures, namely, construct definition, item generation, language testing, content validity, pilot study, and validation study. At first, a total of 20 items in 3 domains were generated based on literature review and expert consultation. After the item selection, the LIDHSQ contains 11 items in three domains: disease-related domain (diarrhoea, abdominal pain, bloody purulent stool, and mucus stool), heat domain (fever, dry mouth, red tongue, yellow fur, and anal burning), and dampness domain (greasy fur and defecation disorder). The Cronbach's alphas of all domains were greater than 0.6. All of the intraclass correlation coefficients were greater than 0.8. The LIDHSQ and domain scores of the patients with LIDHS were higher than those of the patients with other syndromes (P < 0.001). The area under the receiver operating characteristic curve of the LIDHSQ was 0.900, with a 95% confidence interval of 0.872-0.928. When the cut-off value of the LIDHSQ was ≥ 7, the sensitivity and specificity were 0.867 and 0.854, respectively. The LIDHSQ is valid and reliable for measuring LIDHS in UC patients with good diagnostic efficacy. We recommend the use of the LIDHSQ in Chinese UC patients.

ABSTRACT
@#Objective To explore the clinical effect of inner heating dry needle therapy on nonspecific chronic neck pain (NCNP). Methods From October, 2017 to March, 2018, 60 patients with NCNP were randomly divided into needle group (n=30) and magner group (n=30). The needle group received inner heating dry needle therapy, and the magner group received hot magner therapy. They were measured the strain ratio (SR) of bilateral trapezius muscles, scalp clamp muscles, cephalospinal muscles, semispinalis muscles and multifidus muscles with ultrasound elastography before, and one week and one month after treatment, respectively, while they were assessed with Visual Analogue Scale (VAS) of pain and Neck Disability Index (NDI). Results The scores of VAS and NDI decreased in both groups one week and one month after treatment (t>2.693, P<0.05), and decreased more in the needle group than in the magner group (F>8.048, P<0.001). SR of all the muscles decreased in the needle group one week and one month after treatment (F>6.22, P<0.01), and only decreased in the right cephalospinal muscles in the magner group (F=4.35, P<0.05).Conclusion Inner heating dry needle therapy could recover the neck muscle elasticity to relieve pain and improve ceivical function in patients with NCNP.
