To systematically review randomized controlled trials （RCTs） of traditional Chinese medicine （TCM） intervention in ulcerative colitis （UC）， and analyze the characteristics of these studies and their outcome indicators， thereby providing references for the design of future RCTs of TCM intervention in UC and offering evidence supporting the clinical application of TCM in UC. A computerized search was conducted in the China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP， SinoMed， PubMed， Cochrane Library， EMbase， and Web of Science databases for RCTs of TCM intervention in UC published from January 2021 to August 2024. The risk of bias was assessed， and outcome indicators were qualitatively analyzed. A total of 555 RCTs were included， with a sample size of 44 853 participants. The largest sample size was 218 cases， and the smallest was 28 cases， with most studies focusing on 60-100 participants. Of the 386 RCTs that explicitly reported TCM syndrome types， the top three were large intestine dampness-heat syndrome （31.05%）， spleen and kidney yang deficiency syndrome （12.47%）， and spleen deficiency with dampness syndrome （9.17%）. The interventions， ranked by frequency of use， included internal Chinese medicine compounds/preparations （64.5%）， Chinese medicine compounds/preparations with retained enema （18.2%）， internal Chinese medicine compounds/preparations + external TCM treatment （5.95%）， and external TCM treatment alone （4.86%）. The treatment duration was mainly 4-8 weeks （64.86%）， with 61 studies （10.99%） reporting follow-up time. A total of 157 outcome indicators were used， with a frequency of 3 460 occurrences， classified into six domains： TCM syndromes and symptoms （346 occurrences， 10%）， symptoms/signs （541 occurrences， 15.64%）， physical and chemical examinations （2 119 occurrences， 61.24%）， quality of life （107 occurrences， 3.09%）， long-term prognosis （61 occurrences， 1.76%）， and safety events （284 occurrences， 8.21%）. The analysis reveals several limitations in the outcome indicators of TCM intervention in UC， including the lack of a basis for sample size calculation， non-standardized TCM syndrome classification， absence of trial design and registration， inadequate blinding and allocation concealment， adherence issues with interventions， imbalanced selection of surrogate and endpoint indicators， inconsistency in the timing of outcome measurements， design issues that require standardization， and ethical and safety concerns. It is recommended that future studies actively construct a set of core indicators for UC that include standardized TCM syndrome classification， clear efficacy evaluation indicators， key endpoint indicators， and reasonable measurement time points. Long-term prognostic impacts， comprehensive assessments of patients' quality of life， and consideration of economic benefits should be emphasized， providing a basis for the clinical practice of TCM in the treatment of UC.

Asthma is a chronic inflammatory respiratory disease involving multiple cells and cellular components， characterized by recurrent episodes of wheezing， shortness of breath， chest tightness， and coughing， significantly impacting patients' quality of life. The phosphatidylinositol 3-kinase/protein kinase B（PI3K/Akt） signaling pathway， as a crucial hub in intracellular signaling， is widely involved in the regulation of cell growth， proliferation， survival， metabolism， and a series of pathophysiological processes. Its regulatory role in the pathological progression of asthma is particularly significant， specifically in promoting airway inflammation， mediating epithelial mesenchymal transition， accelerating airway remodeling， regulating cell autophagy， inducing mucus hypersecretion， and influencing immune response balance. This study analyzed potential molecular targets of the PI3K/Akt pathway， including activators such as cysteine proteinase inhibitor 1（CST1）， found in inflammatory zone 1（FIZZ1） and free fatty acid receptor 1（FFAR1）， and inhibitors such as human β-defensin-3（hBD-3）， disintegrins， metalloproteinase 33（ADAM33） and interleukin-27（IL-27）， and initially revealed the potential molecular mechanisms of traditional Chinese medicine（TCM） in asthma intervention. Based on this， the authors systematically summarized the efficacy and specific mechanisms of TCM monomers， compounds， and external treatments for asthma by regulating the PI3K/Akt signaling pathway through literature review and analysis， aiming at establishing a robust foundation for the wide application and advanced development of TCM in asthma treatment， offering innovative insights for clinical research and drug development of asthma.

OBJECTIVE： To study the anti-inflammatory and detumescent pharmacodynamic material basis of Jingyaokang capsule， and to provide reference for secondary development， the establishment of quality control method and technological upgrading of the preparations. METHODS： The constituents of Jingyaokang capsule were extracted and separated with different solvents and macroporous adsorption resin to obtain constituent A （overall enrichment part）， constituent B （chloroform extraction part）， constituent C （water-course part） and constituent D （elution part of 60％ ethanol）. Using dexamethasone acetate as positive control， the anti-inflammatory and detumescent effects of Jingyaokang capsule and different extraction parts （constituents A， B， C， D） were investigated by mice ear edema and rat paw edema tests to screen the active fraction. UPLC-Q-TOF-MS method was used to analyze active constituent， identify compounds and attribute medicinal material. RESULTS： Anti-inflammatory and detumescent effects of constituent B （chloroform extraction part）+constituent D （elution part of 60％ ethanol） were similar to those of Jingyaokang capsule in rats or mice， indicating both had synergistic anti-inflammatory and detumescent effects and were active constituents of Jingyaokang capsule. UPLC-Q-TOF-MS detection and identification showed that constituent B contained 13 compounds as strychnine， phellodendrine， periplogenin， tetraketone alcohol， 11-carbonyl-β-mastic acid， attributing to Strychnos nux-vomica， Stephania tetrandra， Periploca sepium， Lycopodium japonicum， Boswellia carterii， etc. Constituent D contained 7 compounds as adenine， hydroxysafflower yellow A， phellodendrine， neoeriocitrin， zingibroside R1， attributing to rainworm， Carthamus tinctorius， Stephania tetrandra， Davallia mariesii， Achyranthes bidentata， etc. CONCLUSIONS： Jingyaokang capsule shows the significant anti-inflammation and detumescent effects. The  chloroform extraction part is synergistic with 60％ ethanol elution part， which are the active constituents of anti-inflammation and detumescence，mainly including alkaloids， flavonoids and boswellic acids.

Spinal cord stimulation (SCS) is a promising technique for treating disorders of consciousness (DOCs). However, differences in the spatio-temporal responsiveness of the brain under varied SCS parameters remain unclear. In this pilot study, functional near-infrared spectroscopy was used to measure the hemodynamic responses of 10 DOC patients to different SCS frequencies (5 Hz, 10 Hz, 50 Hz, 70 Hz, and 100 Hz). In the prefrontal cortex, a key area in consciousness circuits, we found significantly increased hemodynamic responses at 70 Hz and 100 Hz, and significantly different hemodynamic responses between 50 Hz and 70 Hz/100 Hz. In addition, the functional connectivity between prefrontal and occipital areas was significantly improved with SCS at 70 Hz. These results demonstrated that SCS modulates the hemodynamic responses and long-range connectivity in a frequency-specific manner (with 70 Hz apparently better), perhaps by improving the cerebral blood volume and information transmission through the reticular formation-thalamus-cortex pathway.
