The disturbance of the human microbiota influences the occurrence and progression of many diseases. Live therapeutic bacteria, with their genetic manipulability, anaerobic tendencies, and immunomodulatory properties, are emerging as promising therapeutic agents. However, their clinical applications face challenges in maintaining activity and achieving precise spatiotemporal release, particularly in the harsh gastrointestinal environment. This review highlights the innovative bacterial functionalized encapsulation strategies developed through advances in physicochemical and biological techniques. We comprehensively review how bacterial encapsulation strategies can be used to provide physical barriers and enhanced adhesion properties to live microorganisms, while introducing superior material properties to live bacteria. In addition, this review outlines how bacterial surface coating can facilitate targeted delivery and precise spatiotemporal release of live bacteria. Furthermore, it elucidates their potential applications for treating different diseases, along with critical perspectives on challenges in clinical translation. This review comprehensively analyzes the connection between functionalized bacterial encapsulation and innovative biomedical applications, providing a theoretical reference for the development of next-generation bacterial therapies.

Aim To investigate the effect of hypobaric hypoxia on macrophage necroptosis and atherosclerotic plaque instability and explore the underlying mechanisms.Methods Mouse bone marrow-derived macrophages were i-solated and cultured,and divided into control group(21％oxygen concentration)and hypoxia group(3％oxygen concen-tration).After 48 hours,cell necroptosis was detected,and the expression of cell necroptosis related proteins was deter-mined by Western blot.Healthy male ApoE-/-mice were randomly divided into control group and hypobaric hypoxia group.After the intervention for 16 weeks,the plasma lipids and inflammatory cytokines were measured,the areas of ath-erosclerotic plaque and necrotic core were evaluated by HE staining.The content of plaque collagen was detected by Mas-son staining.The number of macrophages in the plaque and the expression of necrotic apoptosis related proteins were de-tected by immunohistochemical staining and Western blot.Results Hypoxia induced increased necrotic apoptosis of macrophages(P＜0.01),while necroptotic inhibitor necrostatin-1(Nec-1)reduced hypoxia induced cell death(P＜0.05);hypoxia leads to a decrease in the expression of adenosine deaminase acting on RNA 1(ADAR1)in macrophages(P＜0.01),and an increase in the expression of Z-DNA binding protein 1(ZBP1),phosphorylated receptor-interacting serine/threonine-protein kinase(p-RIPK3),and phosphorylated mixed lineage kinase domain-like protein(p-MLKL)(all P＜0.01).Compared with the control group,the plasma lipid levels of ApoE-/-mice in the hypobaric hypoxia group did not change significantly(P＞0.05),the plasma inflammatory cytokines(TNF-α,IL-1β,IL-6 and MCP-1)increased(all P＜0.05),the area of atherosclerotic plaque increased(P＜0.05),the area of plaque necrotic core increased,the content of plaque collagen decreased,the number of macrophages increased,the expression of ADAR1 decreased,and the expres-sion of ZBP1 and p-MLKL increased(all P＜0.01).Conclusion Hypobaric hypoxia causes the imbalance of A-DAR1/ZBP1 expression in macrophages,activates RIPK3/MLKL signaling pathway,promotes macrophage necroptosis,in-creases the area of plaque necrosis core,and leads to increase instability of atherosclerotic plaque.

Abstract Modern western medicine typically focuses on treating specific symptoms or diseases, and traditional Chinese medicine (TCM) emphasizes the interconnections of the body’s various systems under external environment and takes a holistic approach to preventing and treating diseases. Phenomics was initially introduced to the field of TCM in 2008 as a new discipline that studies the laws of integrated and dynamic changes of human clinical phenomes under the scope of the theories and practices of TCM based on phenomics. While TCM Phenomics 1.0 has initially established a clinical phenomic system centered on Zhenghou (a TCM definition of clinical phenome), bottlenecks remain in data standardization, mechanistic interpretation, and precision intervention. Here, we systematically elaborates on the theoretical foundations, technical pathways, and future challenges of integrating digital medicine with TCM phenomics under the framework of “TCM phenomics 2.0”, which is supported by digital medicine technologies such as artificial intelligence, wearable devices, medical digital twins, and multi-omics integration. This framework aims to construct a closed-loop system of “Zhenghou–Phenome–Mechanism–Intervention” and to enable the digitization, standardization, and precision of disease diagnosis and treatment. The integration of digital medicine and TCM phenomics not only promotes the modernization and scientific transformation of TCM theory and practice but also offers new paradigms for precision medicine. In practice, digital tools facilitate multi-source clinical data acquisition and standardization, while AI and big data algorithms help reveal the correlations between clinical Zhenghou phenomes and molecular mechanisms, thereby improving scientific rigor in diagnosis, efficacy evaluation, and personalized intervention. Nevertheless, challenges persist, including data quality and standardization issues, shortage of interdisciplinary talents, and insufficiency of ethical and legal regulations. Future development requires establishing national data-sharing platforms, strengthening international collaboration, fostering interdisciplinary professionals, and improving ethical and legal frameworks. Ultimately, this approach seeks to build a new disease identification and classification system centered on phenomes and to achieve the inheritance, innovation, and modernization of TCM diagnostic and therapeutic patterns.

Based on the natures and flavors of herbal medicinals recorded in Shen Nong's Classic of the Materia Medica （《神农本草经》）； Miscellaneous Records of Famous Physicians （《名医别录》）， this study analyzed the characte-ristics of the natures， flavors and combination of medicinals of the two-herb compound formulas in Treatise on Cold Damage and Miscellaneous Diseases （《伤寒杂病论》）.Finally， 31 compound formulas were included， and it was found that the nature and flavor of the herbs in these two-herb compound formulas are closely related to the functions of the compound formulas， such as the common pairing of the acrid and the sweet herbs to warm yang and transform qi， the acrid and the bitter herbs in pairs to regulate and harmonize cold and heat， the sweet and the bitter in pairs to remove dampness and clear heat， the acrid and the acrid in pairs to arrest vomiting and direct qi downward， and the sour and the sweet in pairs to slow the urgent and relieve pain. Regardless of the deficiency or excess nature of the disease， the corresponding two-herb compound formulas often aim to reinforce healthy qi while eliminating pathogenic factors， with some formulas showcasing a unique correspondence between the disease pattern and the symptoms addressed.

AIM:To examine the effects of borneol on inflammation and myocardial remodeling after myocar-dial infarction(MI)in mice,and to investigate the underlying mechanisms.METHODS:Eight-week-old wild-type(WT)C57BL/6 mice and transient receptor potential cation channel subfamily M member 8(TRPM8)gene knockout(TRPM8-/-)mice were randomly divided into sham and MI groups,and were subsequently treated with normal saline(control group)or borneol(borneol group)via gavage.Survival curves were plotted for WT and TRPM8-/-mice with MI treated with or with-out borneol.After 28 d,cardiac function of the mice was assessed through echocardiography,and haemodynamic indexes were evaluated using a multi-channel physiological instrument.Infarct size,myocardial hypertrophy and interstitial fibro-sis were assessed via pathological staining.In addition,inflammatory response in the peri-infarct region was detected.RE-SULTS:The TRPM8 expression was up-regulated in the peri-infarct region of the mice with MI(P＜0.05),and borneol had no effect on TRPM8 expression(P＞0.05).Borneol increased the survival rate,reduced the infarct size,inhibited car-diac remodeling and improved cardiac function in WT mice with MI(P＜0.05 or P＜0.01).However,it did not affect the survival rate,infarct size,myocardial hypertrophy,myocardial fibrosis or cardiac function in TRPM8-/-mice(P＞0.05).Furthermore,borneol reduced inflammatory cell infiltration and the expression of inflammatory cytokines,tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),IL-6 and monocyte chemotactic protein-1(MCP-1),in WT mice(P＜0.05 or P＜0.01)but not in TRPM8-/-mice(P＞0.05).CONCLUSION:Borneol attenuates inflammation,inhibits cardiac re-modeling and improves cardiac function in mice with MI via TRPM8.

【Objective】 To analyze the effects of different fortified feeding methods on nutritional metabolism and growth rate of preterm very low birth weight infants (VLBWI), in order to provide new clues for improving the prognosis of the preterm infants. 【Methods】 A total of 115 cases of premature VLBWI admitted to Department of Neonatology, The First Affiliated Hospital of Kunming Medical University from January 2019 to December 2020 were included in this study, and were divided into fortified breastfeeding group (HFM group), mixed feeding group, and premature formula feeding group (PF group) based on their feeding methods. The effects of different feeding methods on the nutritional metabolism and growth rate of premature VLBWI were analyzed. 【Results】 1) The hospitalization time of infants in the HFM group was shorter than that in PF group and mixed feeding group (t=7.185, 6.924, P<0.05). 2) The proportion of necrotizing enterocolitis (NEC) in the HFM group during hospitalization was lower than that in the PF group (P<0.05); the proportions of late onset septicemia(LOS) and extra uterine growth restriction(EUGR) in the HFM group during hospitalization were lower than those in the PF group (χ²=5.030, 4.147, P<0.05); the proportion of LOS was lower than that of the mixed feeding group(χ²=6.589, P<0.05). 3) During hospitalization, the proportions of abdominal distension, bloody stools and increased eosinophils in the HFM group were lower than those in the PF group (P<0.05), which in mixed feeding group was lower than those in PF group (Fisher exact test, P<0.05). 4) At discharge, the weight and length growth rate of the HFM group were higher than those of the mixed feeding group (t=3.722, 0.425, P<0.001) and the PF group (t =6.015, 0.496, P< 0.001). 【Conclusion】 Fortified breastfeeding can more effectively increase the growth rate of VLBWI in premature infants, improve nutritional metabolism, reduce complications and adverse feeding reactions related to premature infants, and is safer and more effective.

Objective:To study the short-term clinical outcomes of different courses of antenatal corticosteroids (ACS) for preterm twins.Methods:From January 2017 to December 2021, preterm twins with gestational age (GA) 24-34 weeks admitted to the neonatal ward of our hospital and received ACS were retrospectively studied. The infants were assigned into single-course group, partial-course group and multiple-course group according to ACS courses. The short-term clinical outcomes were compared among the groups. SPSS software version 25.0 was used for statistical analysis.Results:A total of 286 infants were enrolled in this study, including 128 in single-course group, 89 in partial-course group and 69 in multiple-course group. Compared with single-course group, the risks of neonatal respiratory distress syndrome (RDS) in both partial-course group ( OR=2.332, 95% CI 1.028-5.293, P=0.043) and multiple-course group ( OR=3.872, 95% CI 1.104-13.584, P=0.034) were higher. The birth length in multiple-course group ( β=-0.016, 95% CI -0.029 - -0.002, P=0.024) was lower than single-course group. Conclusions:The risks of neonatal RDS in preterm twins are higher in partial-course and multiple-course of ACS. A full course of ACS should be used to prevent neonatal RDS until further evidence of effectiveness is available.

Traumatic cerebrospinal fluid leakage commonly presents in traumatic brain injury patients, and it may lead to complications such as meningitis, ventriculitis, brain abscess, subdural hematoma or tension pneumocephalus. When misdiagnosed or inappropriately treated, traumatic cerebrospinal fluid leakage may result in severe complications and may be life-threatening. Some traumatic cerebrospinal fluid leakage has concealed manifestations and is prone to misdiagnosis. Due to different sites and mechanisms of trauma and degree of cerebrospinal fluid leak, treatments for traumatic cerebrospinal fluid leakage varies greatly. Hence, the Craniocerebral Trauma Professional Group of Neurosurgery Branch of Chinese Medical Association and the Neurological Injury Professional Group of Trauma Branch of Chinese Medical Association organized relevant experts to formulate the " Chinese expert consensus on the diagnosis and treatment of traumatic cerebrospinal fluid leakage in adults ( version 2023)" based on existing clinical evidence and experience. The consensus consisted of 16 recommendations, covering the leakage diagnosis, localization, treatments, and intracranial infection prevention, so as to standardize the diagnosis and treatment of traumatic cerebrospinal fluid leakage and improve the overall prognosis of the patients.
