OBJECTIVE To investigate the efficacy and safety of omadacycline in the treatment of macrolide-unresponsive Mycoplasma pneumoniae pneumonia （MUMPP） in children. METHODS A retrospective study was conducted on children aged 1-18 years old with MUMPP who were hospitalized in the Department of Pediatrics， the First Affiliated Hospital of Xinjiang Medical University from January 2022 to June 2025. According to the selection of secondary antibiotics after 72 h of initial treatment with macrolides， they were divided into the omadacycline group and the doxycycline group. Based on conventional treatment， children in the omadacycline group were given intravenous infusion of 2.4 mg/kg （once daily） of omadacycline tosylate， while children in the doxycycline group were given oral doxycycline hydrochloride tablets at 2 mg/kg （twice daily）. The efficacy and safety were compared between the two groups of pediatric patients. Univariate analysis and multivariate Logistic regression analysis were performed on clinical efficacy， and subgroup analysis along with multiple sensitivity analyses were conducted to verify the robustness of the conclusions. RESULTS A total of 284 children with MUMPP were included in this study， with 142 in the omadacycline group and 142 in the doxycycline group. In terms of efficacy， although the hospitalization time of children in the omadacycline group was longer than that in the doxycycline group （ P ＜0.05）， the lung lesion absorption rate and clinical efficacy were significantly higher or better than those in the doxycycline group （ P ＜0.05）. The results of multivariate Logistic regression analysis showed that medication （OR＝5.300， 95%CI： 2.526-11.123）， length of hospital stay （OR＝1.348， 95%CI： 1.167-1.556）， and medication duration （OR＝1.422， 95%CI： 1.169-1.729） were influencing factors of clinical efficacy （ P ＜0.05）. The subgroup analysis results showed that the clinical efficacy of omadacycline was significantly better than that of doxycycline in all subgroups （ P ＜0.05）. The results of multiple sensitivity analysis showed that the regression coefficients B of the four models （gradually adjust variables） before and after inverse probability of treatment weighting were significantly greater than 1 （ P ＜0.05）. In terms of safety， there was no statistically significant difference in the inci dence of adverse drug reactions between the two groups of patients （ χ 2 ＝0.447， P ＝0.504）. CONCLUSIONS In the case of hospitalization and prolonged medication， the efficacy of omadacycline in treating childhood MUMPP is superior to that of doxycycline， and its safety is good.

ObjectiveTo investigate the effects of Shengui Jiangtang Formula on insulin resistance and glucose-lipid metabolism in spontaneous type 2 diabetic db/db mice based on the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/forkhead box protein O1 （FoxO1） signaling pathway， and to provide theoretical foundation for its clinical application through fundamental experiments. MethodsA randomized controlled design was employed in this study. Thirty spontaneous type 2 diabetic db/db mice meeting the inclusion criteria （fasting blood glucose >7.0 mmol·L^-1 and random blood glucose on a different day≥11.1 mmol·L^-1） were selected as the subjects. After stratified block randomization by body weight and blood glucose levels， they were randomly assigned to a model group， a metformin group， and a Shengui Jiangtang formula group， with n=10 per group. Ten db/m mice were used as the normal group. During the 5-week intervention， general indicators （including general condition， fasting blood glucose （FBG）， body weight， and food intake） were recorded weekly. An oral glucose tolerance test （OGTT） was performed at week 5. After 5 weeks， serum was collected to measure glucose-lipid metabolism parameters. Liver tissues were analyzed as follows： Histopathology was observed through hematoxylin and eosin （HE） staining， periodic acid-Schiff （PAS） staining， and Oil red O staining. The expression of proteins and genes related to the PI3K/Akt/FoxO1 signaling pathway was quantitatively analyzed using Western blotting （Western blot） and real-time quantitative polymerase chain reaction （Real-time PCR）. ResultsGeneral observations： The mice in the normal group were generally healthy， exhibited agile responses and had smooth and glossy fur. Compared with the normal group， the mice in the model group displayed typical symptoms of polydipsia， polyphagia， and polyuria， along with listlessness and rough fur. Their food intake， initial body weight， liver weight， and liver index were all significantly higher than those in the normal group （P<0.01）. After 5 weeks of drug intervention， neither the Shengui Jiangtang Formula group nor the metformin group significantly affected the food intake of the model mice. Compared with the model group， no statistically significant difference was observed in liver weight or liver index in the Shengui Jiangtang formula group. Serum biochemical indicators： Compared with the normal group， the model group showed significantly elevated levels of FBG， fasting insulin， homeostatic model assessment of insulin resistance （HOMA-IR）， glycosylated serum protein， and blood lipids. After drug intervention， compared with the model group， the Shengui Jiangtang formula group significantly reduced FBG in the model mice （P<0.01）. The blood glucose levels at all time points during the OGTT in the Shengui Jiangtang Formula group were lower than those in the model group， with statistically significant differences in the 0 min blood glucose and the area under the curve for glucose compared to the model group （P<0.05）. Furthermore， the formula significantly reduced fasting insulin levels， HOMA-IR， and glycosylated serum protein levels （P<0.05）. It also showed a tendency to decrease blood lipids， liver enzymes （aspartate aminotransferase， alanine aminotransferase）， and blood urea nitrogen levels， and a tendency to increase creatinine levels， although these differences were not statistically significant. Liver histomorphology： HE staining indicated that Shengui Jiangtang formula improved the morphological structure of hepatocytes and attenuated steatosis in diabetic mice. Liver PAS staining showed that it increased hepatic glycogen content and promoted hepatic glycogen synthesis in diabetic mice. Oil red O staining demonstrated that it reduced lipid deposition within hepatocytes. Western blot： Compared with the normal group， the model group showed decreased protein expression of PI3K， Akt， p-Akt， and p-FoxO1， and increased FoxO1 protein expression. Compared with the model group， both the metformin and Shengui Jiangtang Formula groups showed increased protein expression of PI3K， Akt， p-Akt， and p-FoxO1， and decreased FoxO1 protein expression. Real-time PCR： Compared with the normal group， the mRNA expression of PI3K and Akt was downregulated （P<0.05）， and the mRNA expression of FoxO1 was downregulated （P<0.05） in the model group. ConclusionShengui Jiangtang Formula can improve insulin resistance and glucose-lipid metabolic disorders in db/db mice. It alleviates hepatic steatosis， promotes hepatic glycogen synthesis， and reduces lipid deposition in these mice. The mechanism by which Shengui Jiangtang Formula improves insulin resistance may be associated with the PI3K/Akt/FoxO1 signaling pathway.

Objective: To investigate the clinical efficacy of autologous platelet-rich plasma (PRP) combined with endoscopy and interventional embolization in treating refractory gastric ulcer hemorrhage in critically ill patients with systemic diseases (sepsis, uremia), and to provide a novel therapeutic option for cases failing conventional treatments. Methods: A case of a 60-year-old male patient with sepsis and uremia complicated by gastric antral ulcer (Forrest Ib) with active bleeding was reported. Autologous venous blood was collected, and PRP was prepared via a two-step centrifugation method. PRP was sprayed endoscopically followed by local injection, and then covered with a thrombin-calcium ion activator to form a gel layer. Initial treatment was performed, followed by consolidation therapy seven days later, along with selective gastroduodenal artery embolization. Results: Hemorrhage was controlled within 24 hours after the initial PRP treatment. Hemoglobin (Hb) increased from 49 g/L to 56 g/L, and coagulation function improved [activated partial thromboplastin time (APTT) decreased from>170 s to 85 s]. A stable coagulum formed on the ulcer surface after the second PRP treatment on day 7. At the 4-week follow-up endoscopic assessment, the ulcer had shrunk to approximately 0.8×1.0 cm, Hb had risen to 92 g/L, and no rebleeding occurred. Conclusion: PRP, acting through mechanical tamponade by a physical barrier and sustained release of growth factors, serves as an effective supplementary treatment for refractory gastric ulcer bleeding, offering dual mechanisms of immediate hemostasis and promotion of mucosal repair. Combining PRP with interventional embolization and multidisciplinary collaboration can further enhance efficacy and may have potential for broader application.

To explore the advantages of traditional Chinese medicine （TCM） and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications （DMC）， refine key pathophysiological insights and treatment principles， and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine， hosted by the China Association of Chinese Medicine， was held in Beijing， 2024. Experts in TCM， Western medicine， and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis， diagnostic and treatment challenges， and mechanism research related to DMC， ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development， research prioritization， and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM， strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.

ObjectiveTo investigate the role of interleukin （IL）-17A in acute inhalational pneumonia induced by the highly drug-resistant and hypervirulent Staphylococcus aureus strain USA300-R in mice. MethodsAn acute inhalational pneumonia model was established in mice using an aerosolized pulmonary delivery technique. RNA sequencing （RNA-seq） and enzyme-linked immunosorbent assay （ELISA） were employed to examine the expression dynamics of Il17a mRNA and IL-17A protein， respectively， in the lungs of infected mice. Il17a knockout （Il17a^-/-） mice were generated using CRISPR/Cas9 gene editing technology. The survival rate， body weight， bacterial load in lung tissue， and histopathological changes were compared between Il17a^-/- and wild-type （WT） mice following inhalational infection with USA300-R. Results12 hours after USA300-R infection， compared to pre-infection， the expression level of Il17a mRNA in lung tissue and the level of IL-17A protein in bronchoalveolar lavage fluid （BALF） increased by approximately 50-fold （P<0.01） and 6-fold （P<0.001）， respectively. Compared to WT mice， Il17a^-/- mice exhibited approximately 10-fold higher bacterial loads in lung tissue at both 12 and 24 hours post-infection （P<0.001， P<0.05）. However， they showed significantly attenuated lung histopathological injury， reduced alveolar wall thickening， markedly decreased neutrophil infiltration， and an approximately 50% improvement in survival rate （P<0.05）. ConclusionIn acute Staphylococcus aureus USA300-R inhalational pneumonia， IL-17A contributes to bacterial clearance by recruiting neutrophils； however， excessive neutrophil infiltration exacerbates pulmonary inflammation and injury， reduces survival rates， and represents a potential therapeutic target.

Objective:To explore the correlation between levels of serum cold-inducible RNA-binding protein(CIRBP), cystatin C(CysC) and cognitive impairment in patients with cerebral small vessel disease(CSVD), as well as the diagnostic value of CI in CSVD.Methods:A total of 90 CSVD patients admitted to the Neurology Department of Zhengzhou People's Hospital from January 2024 to December 2024 were consecutively selected. According to the mini-mental state examination(MMSE) and Montreal cognitive assessment(MoCA), they were divided into non cognitive impairment group(NCI group, n=47) and cognitive impairment group(CI group, n=43). The general clinical data of patients were collected.Fasting venous blood was collected in the morning on the second day of admission to measure serum CIRBP, CysC, homocysteine(Hcy) and high-sentivity C-reactive protein(hs-CRP) levels.A multiple-factor Logistic regression model was applied to identify independent risk factors for CI in CSVD patients, the predictive performance of the model was evaluated by receiver operating characteristic(ROC) curves, and the area under the curve(AUC) value was calculated to quantify the diagnostic accuracy of the model. Results:The levels of Hcy((13.01±4.22)μmol/L vs (11.44±3.00)μmol/L), hs-CRP((2.84±3.01)mmol/L vs (1.81±1.32)mmol/L), CIRBP((2 412.40±967.78)pg/mL vs (1 715.13±971.98)pg/mL), and CysC((1.93±1.08)mg/L vs (1.24±0.87)mg/L) in the CI group were significantly higher than those in the NCI group(all P<0.05). Multiple Logistic regression analysis showed that both CIRBP( OR=1.001, 95% CI=>1.000-1.002, P=0.011) and CysC( OR=1.833, 95% CI=1.056-3.181, P=0.031) were independently influencing factors of the occurrence of CI in CSVD patients(all P<0.05). ROC curve analysis showed that the optimal cutoff values for serum CIRBP and CysC levels to evaluate CI were 1 875.50 pg/mL and 1.42 mg/L, respectively. The AUC (95% CI) were 0.805(95% CI=0.713-0.897, P<0.001) and 0.716(95% CI=0.607-0.825, P<0.001), respectively.The AUC(95% CI) of combined detection of CIRBP+ CysC was 0.820(95% CI=0.733-0.907, P<0.001), with specificity and sensitivity of 89.4% and 67.4%. Conclusion:The serum CIRBP and CysC levels can serve as independent predictors of CI in CSVD patients. Combined testing can improve the accuracy of patient condition assessment and may assist in the diagnosis and prediction of cognitive impairment in CSVD.

BACKGROUND:Plasma coagulation factors have been shown to be strongly associated with chronic kidney disease in many observational studies.Nevertheless,the causal relationship between plasma coagulation factors and chronic kidney disease has not been fully revealed.OBJECTIVE:To assess and explore the association between plasma coagulation factors and chronic kidney disease risk using a two-sample Mendelian randomization approach.METHODS:Genome-wide association study data of 39 plasma coagulation factors with different ID numbers were obtained from the GWAS Catalog database and chronic kidney disease genome-wide association analysis data(ebi-a-GCST003374)were obtained from the Open Genome-Wide Association Study database(IEU Open GWAS),where the sample size of the chronic kidney disease dataset was 117 165 cases and the number of single nucleotide polymorphisms was 2 179 497.Inverse variance weighting,MR-Egger regression,weighted median,weighted mode,and simple mode were used to explore causality.Meanwhile,Cochran Q test was used to assess the variability of single nucleotide polymorphism loci.Horizontal pleiotropy of single nucleotide polymorphisms was verified by MR-Egger intercept test.Sensitivity analyses were performed using the"leave-one-out"method to determine whether the Mendelian randomization results would be confounded by a single single nucleotide polymorphism site.RESULTS AND CONCLUSION:(1)A total of four plasma coagulation factors were associated with chronic kidney disease by Mendelian randomization analysis of 39 plasma coagulation factors and chronic kidney disease.Plasma coagulation factor V(FV)level(odds ratio[OR]=0.922,95％confidence interval[CI]:0.875-0.971,P=0.002),plasma FVII level(OR=0.719,95％CI:0.521-0.991,P=0.044),plasma FXa level(OR=1.113,95％CI:1.009-1.227,P=0.032),plasma antithrombin-level(OR=0.849,95％CI:0.739-0.975,P=0.020)were significantly associated with chronic kidney disease(all P＜0.05).Horizontal pleiotropy and heterogeneity were not detected.(2)Based on the two-sample Mendelian randomization in the genetic epidemiologic method,plasma FVII level,plasma antithrombin-level,and plasma FV level of coagulation factors were protective factors for the risk of chronic kidney disease,and plasma FXa level was a risk factor of chronic kidney disease.(3)The above results confirm that there is a significant potential causal relationship between plasma coagulation factors and chronic kidney disease.Although we analyzed the data of European populations from international databases,these data analyses have a reference value for the study of chronic kidney disease and coagulation factors in China,and they also provide innovative insights into the study of the genetic epidemiology of chronic kidney disease,and they also provide a certain reference value for the in-depth study of the related databases in China,including the China Health and Retirement Longitudinal Study database.Future studies can focus on the assessment of hypocoagulability or hypercoagulability of related coagulation factors in patients with chronic kidney disease.
