OBJECTIVE To systematically evaluate the quality of the Heat-clearing and symptom-relieving formula and screen potential marker components that influence the quality of the formula. METHODS The contents of 11 components (calycosin-7- O - β -D-glucoside, ononin, hyperoside, isoquercitrin, baicalin, baicalein, cryptotanshinone, tanshinone Ⅱ A , tanshinone Ⅰ, senkyunolide A, ferulic acid) in the Heat-clearing and symptom-relieving formula were determined by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Using the contents of the aforementioned components as variables, cluster analysis (CA), principal component analysis (PCA), and orthogonal partial least squares-discriminant analysis (OPLS-DA) were conducted using OriginPro 2024 software and SIMCA 14.1 software; marker components affecting the quality of the Heat-clearing and symptom-relieving formula were then screened based on the criteria of variable importance in the projection (VIP) value>1 and P <0.05. The comprehensive evaluation of 20 batches of samples was carried out using the entropy weight-technique for order preference by similarity to ideal solution(TOPSIS) and grey correlation analysis (GCA) methods. RESULTS The contents of the above 11 components were 7.993-72.866, 4.542-31.228, 727.666-1 901.884, 496.846-1 293.279, 1 995.501-6 779.150, 54.500-241.280, 150.302-304.339, 79.698-189.206, 257.118-682.418, 5.498-21.687, 7.524-26.935 μg/g. CA, PCA and OPLS-DA results showed that 20 batches of samples were grouped into 2 categories. Q1, Q3, Q4, Q7-Q9, Q12, Q15, Q16 were grouped into one category, and the rest were grouped into another category; VIP values of ferulic acid, tanshinone Ⅱ A , baicalin, cryptotanshinone, calycosin-7- O - β -D-glucoside and ononin were all greater than 1 ( P <0.05). Both the entropy weight-TOPSIS and GCA methods showed that the samples ranked in the top 11 according to the euclidean distance and relative correlation degree were Q2, Q5, Q6, Q10, Q11, Q13, Q14, Q17-Q20. CONCLUSIONS The established HPLC-MS/MS method is rapid, accurate and highly sens itive. Combined with chemical pattern recognition analysis, entropy weight-TOPSIS and GCA methods, this method can be used to evaluate the quality of the Heat-clearing and symptom-relieving formula. Ferulic acid, tanshinone Ⅱ A , baicalin, cryptotanshinone, calycosin-7- O - β -D-glucoside and ononin may be the marker components that affect the quality of this formula. The overall quality of 11 batches of the Heat-clearing and symptom-relieving formula, including Q17, is relatively superior.

ObjectiveTo investigate the effects of 7-dehydrocholesterol reductase (DHCR7) in promoting proliferation, migration, and invasion of lung adenocarcinoma cells and the underlying signaling mechanisms. MethodsThe expression level of DHCR7 in lung adenocarcinoma and its prognosis were analyzed by using public databases. DHCR7 protein expression levels in the lung adenocarcinoma cell lines H1299 and A549 were assessed by Western blot, using the normal lung epithelial cell line BEAS-2B as a control. Small interfering RNA (siRNA) was used to knock down DHCR7 expression in H1299 and A549 cells. Assays including colony formation, CCK-8, wound healing, and Transwell experiments were conducted to assess the proliferation, migration, and invasion of the knockdown cells. Next, Western blot was employed to assess the phosphorylation levels of key signaling molecules in the phosphoinositide 3-kinase/protein kinase B (PI3K/AKT), janus kinase/signal transducer and activator of transcription 3 (JAK/STAT3),mitogen-activated protein kinase/extracellular signal-regulated kinase pathway (MAPK/ERK) (p-AKT, p-STAT3, p-ERK). ResultsBioinformatics results indicated that both DHCR7 mRNA and protein were highly expressed in lung adenocarcinoma compared with normal tissues adjacent to cancer. Furthermore, higher DHCR7 mRNA level was associated with poor prognosis (P<0.001). The expression levels of DHCR7 were significantly higher in both H1299 and A549 cells than that in BEAS-2B cells (P<0.05, P<0.01). Compared with si-control, the proliferation, migration, and invasion abilities of si-DHCR7 H1299 and A549 cells significantly decreased. Among the phosphorylated signaling molecules detected, p-ERK was significantly downregulated (P<0.000 1, P<0.01) whereas p-AKT and p-STAT3 levels were not significantly changed. ConclusionDHCR7 has prominent effects in promoting the proliferation, migration, and invasion of lung adenocarcinoma cells, and the underlying mechanisms are related to the MAPK/ERK signaling pathway.

BACKGROUND:The repair process of myocardial injury involves complex cellular and molecular mechanisms,especially mitochondrial calcium homeostasis,macrophage autophagy and pyroptosis pathways.Traditional Chinese medicine(TCM)has shown significant clinical efficacy in improving myocardial injury,but its mechanism of action needs to be thoroughly investigated. OBJECTIVE:To investigate the role of mitochondrial calcium homeostasis-mediated macrophage autophagy and pyroptosis pathways in myocardial injury,and to summarize the progress of TCM in this field. METHODS:A computerized search was performed for relevant literature from the database inception to March 2024 in the Web of Science,PubMed and CNKI.The search terms were"mitochondrial calcium homeostasis,macrophage autophagy,macrophage pyroptosis,traditional Chinese medicine,myocardial injury,myocardial injury reperfusion"in Chinese and English.Through literature review,we analyzed the relationship between mitochondrial calcium homeostasis and macrophage autophagy and pyroptosis,explored the mechanism of their roles in myocardial injury,and summarized the pathways of multi-targeted,multi-pathway effects of TCM. RESULTS AND CONCLUSION:The maintenance of mitochondrial calcium homeostasis has been found to be closely related to the normal function of cardiomyocytes.Macrophages can participate in the repair process of myocardial injury through autophagy and pyroptosis pathways.Autophagy contributes to cell clearance and regulation of inflammatory response,while pyroptosis affects myocardial repair by releasing inflammatory factors.TCM regulates mitochondrial calcium homeostasis and macrophage function through multiple mechanisms.For example,astragalosid regulates calcium homeostasis by lowering mitochondrial membrane potential and inhibiting cytochrome C,and epimedium glycoside plays a role in reducing β-amyloid deposition.In addition,herbal compounds and single drugs promote myocardial repair by activating or inhibiting specific signaling pathways,such as PI3K/AKT and nuclear factor-κB signaling pathways.Future studies should focus on the interactions between mitochondrial calcium homeostasis,autophagy and pyroptosis pathways,as well as how TCM can exert therapeutic effects through these pathways to provide new strategies and drugs for the treatment of myocardial injury.

Objective:To investigate the use of targeted next generation sequencing (tNGS) for the detection of drug resistance in mycoplasma pneumoniae pneumonia (MPP) and analyze the clinical characteristics of MPP.Methods:The clinical data of patients with MPP who underwent bronchoalveolar lavage fluid tNGS at the Department of Respiratory and Critical Care Medicine, The Third People's Hospital of Hubei Province, Jianghan University from February 2022 to February 2024 were collected. According to inclusion and exclusion criteria, 80 patients with MPP were included in this study. The clinical data of the patients were retrospectively analyzed. tNGS of bronchoalveolar lavage fluid was performed to assess drug resistance in MPP. These patients were divided into a drug resistance group ( n = 55) and a non-drug resistance group ( n = 25) based on the presence or absence of the 23SrRNA:A2063G drug resistance mutation. Patient's clinical characteristics were compared between the two groups. The significant indicators from the univariate analysis were introduced into a binary logistic regression model to analyze the independent predictors of drug resistance and their predictive values. Results:The median age of patients with MPP was 38 years, with 53.75% (43/80) being female. Among the patients, 62.50% (50/80) had no underlying diseases, and 68.75% (55/80) exhibited drug resistance, while 42.50% (34/80) had mixed infections. The three most common clinical symptoms were cough (92.50%, 74/80), fever (62.50%, 50/80), and dyspnea (31.25%, 25/80). The most common imaging findings in MPP included patchy shadows (48.75%, 39/80) and consolidation shadows (42.50%, 34/80). Nodular shadows (7.50%, 6/80), tree-in-bud signs (5.00%, 4/80), ground-glass opacities (11.25%, 9/80), bronchial wall thickening (3.75%, 3/80), and pleural effusions (5.00%, 4/80) were not common. Bilateral lesions were present in 40.00% (32/80) of cases. In laboratory examinations, the median levels of inflammatory markers C-reactive protein (39.45 mg/L), procalcitonin (0.08 g/L), and serum amyloid A (168.31 mg/L) were increased. The median or mean levels of other indicators were within the normal range. There were no significant differences between the drug resistance and non-drug resistance groups in terms of gender, age, underlying diseases, clinical symptoms, length of hospital stay, mixed infection rate, mycoplasma pneumoniae (MP)-IgG positivity, MP-IgM level > 300 AU/mL, MP-DNA positivity, percentage of lymphocytes, platelet count, number of lymphocytes, and procalcitonin, D-dimer, prealbumin, lactate dehydrogenase, alanine aminotransferase, aspartate aminotransferase, and albumin levels as well as imaging findings (all P > 0.05). In the drug resistance group, the number of fever days, sequence number, white blood cell count, percentage of neutrophils, C-reactive protein level, and serum amyloid A level were as follows: 4 (0, 7), 24464.00 (2754.00, 43457.00), 7.35 (6.09, 9.84), 73.70 (67.20, 73.70), 39.82 (20.82, 70.40), and 205.40 (81.08, 338.30), respectively. These values were significantly higher than those in the non-drug resistance group [2 (0, 4.50), 658.00 (323.00, 7593.00), 6.12 (5.04, 7.20), 64.45 (58.58, 76.33), 35.63 (4.94, 57.36), 81.30 (12.51, 243.76), Z = -2.43, -4.67, -2.72, -2.36, -2.04, -2.37]. The albumin level in the drug resistance group was 41.50 (38.10, 44.30), which was significantly lower than that in the non-drug resistance group [43.55 (40.03, 46.05), Z = -2.07, P < 0.05]. In the binary logistic regression analysis, the sequence number was identified as an independent predictor of drug resistance. When the sequence number exceeded 1001, the area under the curve value was 0.827, with a sensitivity of 94.5% and specificity of 68.0%. Conclusions:The clinical manifestations of MPP are similar in both the macrolide-resistant and the non-resistant groups. However, the drug-resistant group exhibits a greater number of fever days, higher sequence numbers, and more severe inflammatory responses. The sequence number of MPP can be used to predict drug resistance. When the sequence number exceeds 1001, its predictive value for drug resistance is significantly higher.

Objective:To investigate the clinical characteristics of urea cycle disorder (UCD), the efficacy and safety of glyceryl phenylbutyrate (GPB) therapy in pediatric patients with UCD.Methods:This study was a retrospective, single-arm, multicenter clinical study. The clinical data of 20 pediatric patients with UCD who received GPB treatment at 9 hospitals nationwide between December 2021 and August 2024 were collected. The clinical manifestations, laboratory results, and molecular genetic characteristics were analyzed, ammonia levels and other laboratory results were evaluated pre-post GPB therapy by paired t-tests or Wilcoxon tests. Results:Among the 20 pediatric patients with UCD, there were 8 males and 12 females, and the onset age was 2.8 (1.4, 5.7) years. The ammonia levels were 174 (125, 342) μmol/L at first onset. The symptoms included vomiting in 6 cases, drowsiness in 5 cases, epilepsy in 5 cases, developmental delay in 5 cases, psychiatric and behavioral abnormalities in 3 cases, and lethargy in 1 case, and 18 cases exhibited abnormal liver function. Twenty cases included 6 UCD subtypes, with 11 cases being ornithine transcarbamylase deficiency. A total of 27 variants were identified, 11 (41%) of which were novel. The age of patients who began GPB therapy was 4.0 (1.5, 6.6) years. Ten cases stopped GPB after 4.2 (3.4, 5.3) months, with 4 patients undergoing liver transplantation and 6 discontinuing for financial reasons. The remaining ten patients continued GPB therapy for 11.6 (8.6, 14.0) months. The duration of GPB treatment was 6.0 (4.2, 12.3) months, at the final visit, the levels of ammonia, platelets and aspartate aminotransferase were lower compared to those of pre-treatment (all P<0.05). The serum albumin level was higher than that of pre-treatment ( P=0.016). Two patients suffered only one episode of acute hyperammonaemia, with ammonia levels of 232 and 141 μmol/L, respectively. Nine cases experienced adverse effects potentially related to GPB, decreased appetite in 6 cases, vomiting in 3 cases, abnormal skin oil odor in 2 cases, somnolence, fatigue and diarrhea each in 1 case, with symptoms improved within 6 (3, 10) days. Conclusions:UCD primarily manifests with neurological and gastrointestinal symptoms, and early diagnosis of UCD could be achieved through the analysis of ammonia. GPB may effectively reduce ammonia levels in UCD pediatric patients, with favorable safety and tolerability.

Objective:This study identifies independent predictive indicators to distinguish autoimmune gastritis from Helicobacter pylori ( H. pylori)-induced atrophic gastritis and validates their diagnostic performance to compare laboratory indicators of autoimmune gastritis and H. pylori-induced atrophic gastritis. Methods:A retrospective comparison of laboratory examination indicators was conducted for chronic atrophic gastritis patients with involvement of the gastric fundus and corpus, who were followed up at the Department of Gastroenterology, Xijing Hospital, from January 2014 to September 2024. Receiver operating characteristic (ROC) curves were utilized to determine the optimal cutoff points and corresponding diagnostic thresholds. In addition, multivariate logistic regression analysis was conducted to identify independent predictive indicators for autoimmune gastritis, with further assessment in a validation cohort.Results:A total of 139 patients with autoimmune gastritis and 209 patients with H. pylori-induced atrophic gastritis were included. Pepsinogen (PG) Ⅰ levels and the PG Ⅰ/PG Ⅱ ratio in patients with autoimmune gastritis were significantly lower than in those with H. pylori-induced atrophic gastritis [11.0 (4.8, 22.5) vs. 41.8 (32.2, 59.9) μg/L, U=722.00, P<0.001; 1.24 (0.75, 3.54) vs. 5.76 (4.31, 7.12), U=817.00, P<0.001], while gastrin levels were significantly higher [375 (84, 738) vs. 49 (35, 81) ng/L, U=378.00, P<0.001]. PG Ⅰ was identified as an independent predictive variable, with an area under the ROC curve of 0.847 (95% CI 0.791-0.904), sensitivity of 77.6%, specificity of 91.8%, positive predictive value of 80.5%, and negative predictive value of 90.5%. Conclusions:Significant differences in laboratory indicators were observed between autoimmune gastritis and H. pylori-induced atrophic gastritis in chronic atrophic gastritis involving gastric fundus and corpus. Besides, PG Ⅰ demonstrated good diagnostic performance in identifying autoimmune gastritis and can effectively differentiate between different types of atrophic gastritis.
