Tuberculosis (TB), a chronic infectious disease caused by Mycobacterium tuberculosis, is primarily airborne and remains a global health problem, especially in resource-limited countries and regions. The emergence of drug resistance in M. tuberculosis has rendered the existing means ineffective in the treatment of TB. Therefore, research in new therapeutic directions has become imperative. In this review, we outline functional peptides in terms of the mechanisms of action, anti-TB attempts, advantages and disadvantages, and latest advances, aiming to analyze the research progress in anti-TB peptides. Furthermore, we investigate the potential applications of bioactive compounds found in traditional Chinese Medicine within the context of peptides.

Objective:To investigate the protective effects of p53/glucose transporter 4 (GLUT4) regulation on cardiomyocyte injury induced by high glucose combined with hypoxia/reoxygenation.Methods:Human myocardial AC16 cells were treated with 33 mmol/L glucose and a hypoxic chamber to establish an in vitro model of high glucose combined with hypoxia/reoxygenation. Based on the glucose concentration in the medium and hypoxia/reoxygenation conditions, AC16 cells were divided into control group, high glucose group, hypoxia/reoxygenation group and high glucose combined with hypoxia/reoxygenation group. On the basis of high glucose combined with hypoxia/reoxygenation group, cells were transfected with empty vector, p53 small interfering RNA (siRNA), and co-transfected with p53 and GLUT4 siRNA to establish negative control group, sip53 transfection group, and sip53+siGLUT4 transfection group, respectively. Western blotting was used to detect the levels of hypoxia-inducible factor-1α (HIF-1α), p53, GLUT4, dynamin-related protein 1 (Drp1), mitofusin 2 (Mfn2), B-cell lymphoma-2 (Bcl-2), Bcl-2 associated X protein (Bax) and cysteine aspartic acid specific protease-3 (Caspase-3). The levels of reactive oxygen species were detected using the 2′,7′-dichlorodihydrofluorescein diacetate fluorescent probe. Mitochondria were labeled with the Mito-Tracker Deep Red FM fluorescent probe to assess mitochondrial morphology and their related parameters. Mitochondrial membrance potential was meausred using the JC-1 detection kit. Adenosine triphosphate (ATP) content was determined using an ATP assay kit. Glucose uptake ability was evaluated by measuring the fluorescence intensity of 2-[ N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl) amino]-2-deoxy- D-glucose (2-NBDG) using a multifunctional microplate reader.

Bone marrow suppression is one of the common adverse reactions to radiotherapy and chemotherapy. Anticancer treatments such as radiotherapy and chemotherapy first directly damage the patient′s peripheral blood cells, impairing qi and blood; further, they damage the actively proliferating cell populations in the bone marrow, impairing yin and blood; and then they interfere with hematopoietic stem cells, impairing essence and blood. This process is rapid and intense, consistent with the characteristics of " acute deficiency syndrome" , marked by sudden onset, rapid changes, critical condition, complexity and variability, multiple complications, and poor prognosis. Given this, its diagnosis and treatment should differ from those of general deficiency syndromes. This paper advocates the principles and ideas of diagnosis and treatment such as " preventing first and treating early to prevent changes; supplementing for deficiency and strengthening vital qi to eliminate pathogenic factor; urgent rescue for critical conditions, no time to lose; and comprehensive supplementing throughout the process, with severe cases requiring singular action" . This approach is intended to provide theoretical reference and practical guidance for bone marrow suppression after radiotherapy and chemotherapy.

Objective: To determine the clinical efficacy of platelet-rich plasma (PRP) injection combined with warm acupuncture and moxibustion for treating patients with knee osteoarthritis and cold dampness obstruction syndrome. Methods: One hundred and twenty-eight patients with knee osteoarthritis and cold dampness obstruction syndrome who visited the Rehabilitation Department and Orthopedics Department of the Second Affiliated Hospital of Anhui University of Chinese Medicine from January 2023 to March 2024 and who met the inclusion and exclusion criteria were randomly divided into an experimental (n=64) and control group (n=64) using the random number table method. The experimental group was treated with PRP injection combined with warm acupuncture and moxibustion, whereas the control group was treated with normal saline injection combined with warm acupuncture and moxibustion treatment. PRP and normal saline injections were administered once every two weeks, a total of four times. Patients were treated with warm acupuncture and moxibustion once a day, six times a week, for four consecutive weeks. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Traditional Chinese Medicine (TCM) syndrome, visual analog scale (VAS), and Lysholm scores were determined before treatment, at week 4 and week 8 of treatment, and week 16 of follow-up. Serum interleukin-6 (IL-6), matrix metalloproteinase-3 (MMP-3), tumor necrosis factor-α (TNF-α), osteoprotegerin (OPG), bone gla protein(BGP), and cartilage oligomeric matrix protein (COMP) levels were compared between the two groups before and after 8 weeks of treatment. The clinical efficacy and safety indicators between the two groups were also compared. Results: There was no statistical difference in baseline data such as gender, age, disease duration, and body mass index between the two groups of patients. Compared with before treatment, both groups showed decreased WOMAC total and subscale, TCM syndrome total score and symptom scores, and VAS scores, and an increase in Lysholm scores at 4, 8, and 16 weeks after treatment. After treatment, serum IL-6, MMP-3, TNF-α, and COMP levels decreased, whereas serum OPG and BGP levels increased (P<0.05). Compared with the control group, patients in the experimental group showed decreased WOMAC total and subscale, TCM syndrome total score and symptom scores, and VAS scores, and an increase in Lysholm score at 4, 8, and 16 weeks after treatment. Compared with the control group, patients in the experimental group showed decreased serum IL-6, MMP-3, TNF-α, and COMP levels and an increase in serum OPG and BPG levels after treatment (P<0.05). The total effective rate of the experimental group was 91.94%, higher than that of the control group (81.97%; P<0.05). Conclusion PRP injection combined with warm acupuncture and moxibustion can improve various TCM symptoms, improve knee joint function and bone metabolism, and reduce inflammation in patients with knee osteoarthritis and cold dampness obstruction syndrome.

AIM: To analyze the clinical features and multimodal imaging features of peripapillary hyper-reflective ovoid mass-like structure(PHOMS).METHODS: Retrospective observation study. Totally 35 patients(56 eyes)with PHOMS that diagnosed in the Affiliated Eye Hospital of Nanjing Medical University from January 2020 to March 2024 were included in the study. All patients underwent fundus photography, fundus fluorescein angiography, fundus autofluorescence, optical coherence tomography, and B-ultrasound.RESULTS:PHOMS occurred across diverse age groups, with an insidious onset often detected incidentally during routine ophthalmic examinations. More patients came to hospital for refractive errors due to blurred vision The boundary of the optic disc is blurred on fundus photography, and the nasal eminence is more significant, showing a “C” shaped halo. No obvious abnormal fluorescence was observed on fundus autofluorescence and fundus fluorescein angiography during different periods. An elevated appearance in vary degrees with more prominent in the nasal parts was showed on different OCT scans. Vertical scanning on the nasal side of the optic disc showed the best PHOMS structure, which could be seen under the retinal nerve fiber layer and on the Bruch membrane, with sharply marginated hyper-reflective ovoid mass-like structures, and no shielding effect on the choroid. The higher the elevation, the larger the volume. Ocular B-mode ultrasound showed a pre-optic disc bulge on the posterior wall of the eyeball, and there was no strong signal echo in it.CONCLUSION:PHOMS can be found frequently in myopic patients and often asymptomatic. Transient vision loss and floaters may occur in symptomatic cases. The most typical OCT feature is a nasally located hyper-reflective ovoid structure with distinct margins.

OBJECTIVE: To explore the displacement and pressure distribution of American Chiropractic in a model of third lumbar syndrome based on finite element analysis. METHODS: On March 2021, CT and MRI images of a 23-year-old male patient with right third lumbar syndrome were selected. A 3D stl model was established using Mimics and CATIA, and the data was imported into Hypermesh, Abaqus & ANSYS. The elastic modulus and Poisson's ratio of the affected side material were adjusted to establish its finite element model. Based on the comparison of the operating positions and routines of the American Chiropractic and the lumbar spine oblique pull method, but with differences in the focus and direction of force, the experimental group simulated the American Chiropractic with the healthy side (left side) lying position of the model. The upper endplate of L₃ and the lower part below L₃ twisted accordingly with the body position, we applied a vertical forward thrust of 246 N to the plane formed by the L₄, L₅ spinous processes and L₄ upper articular processes;The control group simulates the oblique pull method of the lumbar spine, requiring the model to lie on the healthy side (left side), fix the upper endplate of L₄, and perform a horizontal rotation along the longitudinal axis of L₃ vertebral body. At this time, the contact force in the upward direction is also set to 246 N. Compare the displacement and stress differences between the L₁-L₅ intervertebral bodies, intervertebral discs, articular processes, and transverse process muscles in two intervention models. RESULTS: ① Under safe load conditions, a test force of 246 N was applied to the model, and the maximum vertebral displacement occurred on the right side of the L₃ vertebral body (1.197 mm) after manual intervention in the control group. The vertebral displacement between L₁-L₅ induced by manual intervention in the experimental group was smaller than that of the control group's manual intervention (P<0.05). ② The maximum vertebral body stress occurred on the right side of the L₃ vertebral body after manual intervention in the control group (98.425 MPa). The stress on each vertebral body formed by the experimental group's manual intervention was lower than that of the control group's manual intervention (P<0.05). ③The maximum intervertebral disc stress occurred on the right side of the L_2,3 intervertebral disc (6.282 MPa) after manual intervention in the control group. ④ The maximum joint process stress occurred on the right side of the L₄ upper joint process after manual intervention in the experimental group (1.587 MPa). The joint process stress on the left side below L₁ and the left side above and below L₂ induced by manual intervention in the experimental group was lower than that of the control group (P<0.05). ⑤The maximum stress on the intertransverse process muscle was observed at the right lateral L₃ process end (31.960 MPa) of L_3,4 in the control group after manual intervention. The stress on the L_2,3 and L_4,5 segments of the intertransverse process muscle induced by manual intervention in the experimental group was lower than that of the control group's manual intervention (P<0.05). CONCLUSION The mechanical feedback of the L₁-L₅ vertebral body, the lower left side of the articular process L₁, the upper and lower left side of the articular process L₂, and the L_2,3 and L_4,5 segments of the transverse process muscle in the model indicates that performing American Chiropractic for the treatment of third lumbar transverse process syndrome can accurately hit the target pain point and allow the patient's tissue to form a low stress and low tension state after manual operation, thereby reducing the possibility of tissue damage caused by hypertonia after intervertebral joint movement, making it relatively safe. The application of American Chiropractic will be a new supplement to the traditional treatment plan for third lumbar transverse process syndrome.

Hepatic stellate cells (HSCs) are the primary fibrogenic cells in the liver, and their activation plays a crucial role in the development and progression of hepatic fibrosis. Here, we report that retinoid X receptor-alpha (RXRα), a unique member of the nuclear receptor superfamily, is a key modulator of HSC activation and liver fibrosis. RXRα exerts its effects by modulating calcium/calmodulin-dependent protein kinase kinase β (CaMKKβ)-mediated activation of AMP-activated protein kinase-alpha (AMPKα). In addition, we demonstrate that K-80003, which binds RXRα by a unique mechanism, effectively suppresses HSC activation, proliferation, and migration, thereby inhibiting liver fibrosis in the CCl₄ and amylin liver NASH (AMLN) diet animal models. The effect is mediated by AMPKα activation, promoting mitophagy in HSCs. Mechanistically, K-80003 activates AMPKα by inducing RXRα to form condensates with CaMKKβ and AMPKα via a two-phase process. The formation of RXRα condensates is driven by its N-terminal intrinsic disorder region and requires phosphorylation by CaMKKβ. Our results reveal a crucial role of RXRα in liver fibrosis regulation through modulating mitochondrial activities in HSCs. Furthermore, they suggest that K-80003 and related RXRα modulators hold promise as therapeutic agents for fibrosis-related diseases.

Breast cancer remains a substantial threat to women's health and is one of the most prevalent malignant tumors in women.Because breast cancer onset is closely associated with female physiological characteristics,this article proposes that breast cancer be classified as a"women's miscellaneous diseases"and that its treatment be explored from this perspective.Drawing from Chapter 8 on Golden Chamber of Prescriptions for Miscellaneous Diseases in Women of Synopsis of Golden Chamber,the initial pathogenesis of breast cancer is associated with"emotional stress,improper lifestyle,deficiency,cold,and stagnation."The fundamental mechanism behind its formation is"blood cold accumulation and hardened masses."Specifically,emotional imbalance and improper lifestyle habits contribute to the combined invasion of the uterus by"deficiency,""accumulated cold,"and"stagnant qi."Over time,"cold-blood stasis accumulates at the uterine ostium,"and the cold and the stasis ascends from the uterus along the thoroughfare and conception vessels,obstructing the breast collaterals.This combination of yang qi stagnation and yin cold congealment,ultimately leads to the development of breast cancer.The treatment principle should focus on"activating yang and dispersing cold."A therapeutic approach centered on Wenjing Decoction combined with Xiaoyao Powder can be adapted based on the stage and type of breast cancer while also considering the dynamic interplay between pathogenic factors and healthy qi,along with shifts in deficiency and excess patterns of disease.By adhering to the principles of consistency and flexibility and integrating disease and syndrome differentiation,the goal is to develop precise and personalized treatment strategies to improve clinical outcomes.
