ObjectiveTo investigate the mechanism of Huazhuo Jiedu prescription in treating ulcerative colitis (UC) by regulating mitophagy. MethodsThe genes related to mitophagy and UC were retrieved from GeneCards, and then the common genes of mitophagy and UC were analyzed by metascape to identify the genes related to mitophagy in UC. Animal experiments were carried out to decipher the mechanism by which Huazhuo Jiedu prescription treated UC by regulating mitophagy. Sixty C57BL/6 male mice were randomized into normal, model, high-, medium-, and low-dose (50, 25, 12.5 g·kg-1, respectively) Huazhuo Jiedu prescription, and mesalazine (0.52 g·kg-1·d-1) groups, with 10 mice in each group. After successful modeling by the dextran sulfate sodium-free drinking method, the colonic mucosal damage was observed by hematoxylin-eosin staining, and the ultracellular structure of colon mucosa was observed by transmission electron microscopy. The expression levels of mitophagy-related proteins PTEN-induced putative kinase 1 (PINK1) and Parkin protein were determined by Western blot. The expression of prohibitin 2 (PHB2), ubiquitin-specific protease 15 (USP15), ubiquitin-specific protease 30 (USP30) in the colon tissue was detected by immunofluorescence (IF). ResultsAll the drug intervention groups showed ameliorated pathological manifestations of the colonic mucosa and improved mitochondrial structures in UC mice. Compared with the normal group, the model group demonstrated up-regulated protein levels of PINK1 and Parkin (P<0.05), enhanced average fluorescence intensity of PHB2 (P<0.05), and weakened average fluorescence intensity of USP15 and USP30 (P<0.05). Compared with the model group, the mesalazine group and the high- and medium-dose Huazhuo Jiedu prescription groups showcased down-regulated protein levels of PINK1 and Parkin (P<0.05), decreased average fluorescence intensity of PHB2 (P<0.05), and enhanced average fluorescence intensity of USP15 and USP30 (P<0.05). The low-dose Huazhuo Jiedu prescription group showed down-regulated protein levels of PINK1 and Parkin (P<0.05), weakened average fluorescence intensity of PHB2 (P<0.05), and enhanced average fluorescence intensity of USP15 and USP30 (P<0.05). ConclusionHuazhuo Jiedu prescription can attenuate the intestinal mucosal injury and improve the mitochondrial cell ultrastructure in UC mice by regulating the expression of PINK1-Parkin pathway and inhibiting excessive mitophagy.

ObjectiveTo explore the therapeutic effect and mechanism of Xianglian Huazhuo prescription on chronic atrophic gastritis (CAG) in rats based on the Hedgehog signaling pathway. MethodsThe CAG rat model was established by sodium salicylate, N-methyl-N′-nitro-N-nitroguanidine (MNNG), and irregular feeding. The successfully modeled rats were randomly divided into a model group (180 mg·L-1), a moradan group (1.4 g·kg-1), and Xianglian Huazhuo Prescription groups with high, medium, and low doses (36, 9, 18 g·kg-1), followed by drug intervention. Hematoxylin-eosin (HE) staining was used to observe morphological changes in the gastric mucosa. Transmission electron microscopy was used to observe the ultrastructure of gastric mucosa cells. Real-time quantitative polymerase chain reaction (Real-time PCR) was used to detect the mRNA expression of Sonic Hedgehog (Shh), Patched 1 (Ptch1), and Glioma-associated oncogene homolog 1 (Gli1). Western blot was used to detect the protein expression levels of Shh, Ptch1, and Gli1 in the gastric mucosa. Immunohistochemistry was used to observe the protein expression of the epithelial marker E-cadherin. ResultsCompared with the normal group, the CAG model group showed a reduction in gastric mucosal intrinsic glands and infiltration of inflammatory cells. The ultrastructure of gastric mucosal cells showed nuclear pyknosis, fewer mitochondria, and abnormal mitochondrial structure. The mRNA and protein expression of Shh, Ptch1, and Gli1 in the gastric mucosa were significantly decreased (P<0.05), and E-cadherin protein expression was decreased. Compared with the model group, the intervention groups showed varying degrees of improvement in histopathological morphology and cellular ultrastructure. The mRNA and protein expression of Shh, Ptch1, Gli1, and E-cadherin increased to varying degrees. Xianglian Huazhuo Prescription upregulated the expression of key Hedgehog pathway factors and E-cadherin at both the mRNA and protein levels (P<0.05). ConclusionXianglian Huazhuo prescription has a therapeutic effect on CAG in rats, and its mechanism may be related to activation of the Hedgehog signaling pathway and inhibition of epithelial-mesenchymal transition (EMT).

Chinese materia medica has a wide range of clinical applications, but it has many active ingredients with different physicochemical properties, and the target organs, action pathways and mechanisms for different ingredients to exert their efficacy are not the same. Therefore, it is difficult to design and develop a co-delivery system loading multiple components of Chinese materia medica to maximize the synergistic therapeutic efficiency. Based on the characteristics of effectiveness and functionality of active ingredients, the strategies for multi-component co-delivery of Chinese materia medica can be categorized into two types:firstly, based on the effectiveness of active ingredients, new carriers such as liposomes, nanoparticles can be constructed to load multi-components of Chinese materia medica. secondly, based on the functionality of some active ingredients of Chinese materia medica, they are employed in the construction of co-delivery system, which can give play to the dual characteristics of their own efficacy and preparation functions. In this paper, we summarized the relevant research progress of the above two types of multi-component co-delivery strategies, and mainly discussed the pharmaceutical functions of the active ingredients in co-delivery systems, in order to find a more suitable multi-component co-delivery strategy, promoting the design and development of new delivery systems of Chinese materia medica.

ObjectiveTo identify factors related to the occurrence of choking and coughing while eating in the disabled elderly and conduct importance matrix analysis to provide a reference basis for controlling choking on food in the disabled elderly. MethodsA convenience sampling method was used to select 80 disabled elderly individuals in a hospital between October 2019 and April 2022 as the study population. The occurrence of choking and coughing while eating was recorded, and a questionnaire was administered to collect general information. Additionally, assessments were conducted using the intelligent mental status examination scale (MMSE), oral health checklist (BOHSE), eating assessment tool⁃10 (EAT-10), and chewing function evaluations. Univariate and multifactorial analyses were conducted to analyze the influencing factors of choking and coughing while eating in the elderly with disabilities. ResultsThe incidence of choking and coughing while eating was 52.50% (42/80) among the 80 disabled elderly. The degree of disability (OR=2.895, 95%CI: 1.352‒6.201), age (OR=4.040, 95%CI: 1.121‒14.562), BOHSE score (OR=2.473, 95%CI: 1.002‒6.102), EAT-10 score (OR=5.345, 95%CI: 2.112‒13.527), and chewing function score (OR=3.453, 95%CI: 1.247‒9.562) were identified as risk factors for choking and coughing while eating in the disabled elderly. The MMSE score (OR=0.343, 95%CI: 0.135‒0.869) was identified as a protective factor. The importance matrix analysis indicated that EAT-10 score, MMSE score, and chewing function had high importance with slightly lower difficulty in improvement, and were thus listed as items in the priority improvement area. Age and degree of disability had high importance and high difficulty in improvement, and therefore belonged to the suboptimal improvement area. BOHS score was slightly lower both in importance and difficulty of improvement, entering the alternative improvement area. ConclusionAge, degree of disability, BOHSE score, EAT-10 score, and chewing function score are risk factors for the occurrence of choking and coughing while eating, while the MMSE score is a protective factor. The importance matrix analysis can provide a basis for targeted intervention in clinical practice.

Objective:To investigate the consistency of myocardial extracellular volume between systole and diastole using dual-layer detector spectral CT.Methods:This was a cross-sectional study. Thirty-five patients who underwent cardiac spectral CT examination in West China Hospital of Sichuan University from April 2022 to December 2022 were retrospectively collected. Hematocrit was collected within 3 days before the CT scan. The delayed phases holographic spectral images in systole (45%) and diastole (75%) were obtained using dual-layer spectral CT. CT data were processed using a spectral post-processing workstation, and the extracellular volume (ECV) based on iodine density images, referred as CT-ECV, in systolic and diastolic phases were calculated, respectively. According to the American Heart Association′s 16-segment model of left ventricular, the standard short-axis images were constructed, and the myocardium was standardized into 16 segments at the basal, mid-cavity, and apical levels of the left ventricle. Two radiologists performed a subjective evaluation in the image quality of the CT-ECV images of the whole heart and the three sections in systole and diastole using a "five-point" scale. The ECV of the 16 segments and the whole heart in systole and diastole was calculated. The consistency of subjective evaluations between systole and diastole was assessed using Kappa statistics. Wilcoxon signed-rank tests were used to compare the differences in scores between systole and diastole. Paired sample t-test was used to compare the differences in CT-ECV scores between systole and diastole. The intraclass correlation coefficient was used to test the intra-and inter-observer consistency of CT-ECV measurements between two radiologists. P<0.05 was statistically significant. Results:There was good agreement between the two radiologists on subjective scores of CT-ECV image quality between systole and diastole ( Kappa>0.80), and there was no statistical difference in image quality among the basal, mid-cavity, and apical levels of the left ventricle and whole heart between systole and diastole ( P>0.05). The systolic and diastolic CT-ECV for the entire heart obtained through the delay phase were (33.29±3.46)% and (33.50±3.39)%, respectively, with no statistically significant difference ( t=-0.78, P=0.442). CT-ECV in systole and diastole were (34.15±3.94)% and (35.30±3.99)% for segment 8, (34.03±3.76)% and (35.46±3.74)% for segment 9, and (33.98±3.32)% and (35.05±3.98)% for segment 14, respectively. The mean values of the systolic CT-ECV of segments 8, 9 and 14 were significantly lower than those of diastolic CT-ECV ( t=-2.65, -3.26, -2.42, P=0.012, 0.003, 0.022, respectively). The ICCs for CT-ECV measurements of 16 segments by the two radiologists were greater than 0.90 in both systolic and diastolic, indicating good agreement. Conclusions:There is no significant difference in whole heart CT-ECV values between systolic and diastolic myocardial ECV based on dual-layer spectral CT. However, minor differences (less than 2%) are found between systolic and diastolic myocardial CT-ECV for some segments. Myocardial CT-ECV measurement should be performed on the same segment during the same phase to obtain stable and accurate ECV values.

Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired clonal hematopoietic stem cell disease caused by abnormal expression of glycosylphosphatidylinositol (GPI) on the cell membrane due to mutations in the phosphatidylinositol glycan class A(PIGA) gene. It is commonly characterized by intravascular hemolysis, repeated thrombosis, and bone marrow failure, as well as multiple systemic involvement symptoms such as renal dysfunction, pulmonary hypertension, swallowing difficulties, chest pain, abdominal pain, and erectile dysfunction. Due to the rarity of PNH and its strong heterogeneity in clinical manifestations, multidisciplinary collaboration is often required for diagnosis and treatment. Peking Union Medical College Hospital, relying on the rare disease diagnosis and treatment platform, has invited multidisciplinary clinical experts to form a unified opinion on the diagnosis and treatment of PNH, and formulated the
