OBJECTIVE To form an expert consensus on the clinical application of parenteral direct thrombin inhibitors （DTIs） in patients during the perioperative period. METHODS Led by Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital （the Affiliated Hospital of UESTC）， a multidisciplinary working group was established. Through literature review and the Delphi method， clinical questions related to the rational perioperative use of parenteral DTIs were identified. A structured design was adopted using the “Population-Intervention-Comparison-Outcome” framework； systematic searches were conducted in CNKI， Medline， Embase and other databases. Relevant evidence from randomized controlled trials and cohort studies was included and synthesized. Evidence quality was assessed using the Grades of Recommendations Assessment，Development and Evaluation （GRADE） approach， and recommendations were formulated through multiple rounds of Delphi surveys and expert consensus meetings. RESULTS &CONCLUSIONS Seven recommendations （each with an expert consensus rate exceeding 90%） on the use of parenteral DTIs in perioperative patients were developed. These recommendations specify drug selection， dosing ranges， key monitoring points， and safety management strategies for parenteral DTIs in various scenarios， including the perioperative period of ventricular assist device implantation， the perioperative period of cardiac surgery， perioperative patients with lower-extremity atherosclerotic disease， the perioperative period of percutaneous coronary intervention in patients with acute coronary syndrome， the perioperative period of carotid artery stenting in patients with carotid stenosis， the perioperative period of patients with right heart thrombosis， and patients who develop related thrombosis and dysfunction after a central venous catheter insertion. In addition， warning and management pathways for perioperative bleeding and thrombotic events were proposed. This expert consensus， which is formulated based on the best available evidence， provides evidence-based guidance for standardized and individualized use of parenteral DTIs in perioperative period.

ObjectiveTo investigate the quality markers of Xiaoqinglong granules（XQLG） for treating bronchial asthma using the analytic hierarchy process（AHP）-entropy weight method（EWM）， network pharmacology and high performance liquid chromatography（HPLC） content determination. MethodsEffectiveness， testability and peculiarity component data of XQLG in treating bronchial asthma were constructed through database retrieval， literature review， and network pharmacology. Subsequently， AHP-EWM was used to quantitatively identify and weight the control layer and element layer， the relevant compounds were selected as candidate quality markers based on comprehensive scores. Further comparison of reference substances and establishment of HPLC content determination method were used to determine the potential quality markers of XQLG， which were verified by molecular docking with disease targets. ResultsA total of 13 components， including glycyrrhizic acid， paeoniflorin， schisandrol A， isoliquiritigenin， 6-gingerol， ephedrine， liquiritin， albiflorin， liquiritigenin， 6-shogaol， pseudoephedrine， cinnamic acid and cinnamaldehyde， were identified as potential quality markers of XQLG by AHP-EWM. Quantitative analysis indicated that all aforementioned quality markers could be detected in 13 batches of XQLG， indicating that it had stable testability as a quality marker. Among these 13 batches of samples， ephedrine and paeoniflorin exhibited good consistency in content， while pseudoephedrine and cinnamaldehyde showed poor consistency. Molecular docking analysis revealed that the 13 compounds exhibited binding energies with the core targets -2.11 kcal·mol^-1， indicating that the 13 compounds could spontaneously bind to the disease targets， which may be the material basis for the treatment of bronchial asthma with XQLG. ConclusionIn this study， 13 compounds were screened by AHP-EWM combined with network pharmacology and HPLC as quality markers for the treatment of bronchial asthma by XQLG， laying the foundation for enhancing the quality standards of this preparation.

Objective: To investigate the role of murine double minute 2(MDM2) in dihydroartemisinin′s(DHA) inhibition of lung adenocarcinoma cell proliferation and migration. Methods: CCK8 assay was used to detect the inhibitory effect of gradient concentrations of DHA(0, 5, 10, 25, 50 and 100 μmol/L) and time gradients(0, 24, 48, and 72 h) on the proliferation of lung adenocarcinoma A549 and PC9 cells, and the half maximal inhibitory concentrate(IC50) were calculated respectively. Colony formation and scratch assays were used to detect the inhibitory effects of DHA on colony formation and migration of A549 and PC9 cells. Western blot was used to detect the inhibitory effects of DHA on MDM2 expression and epithelial-mesenchymal transition(EMT)-related proteins E-cadherin and N-cadherin. The promoting effects of MDM2 on proliferation, migration and EMT of lung adenocarcinoma cells were verified by small interfering RNA-mediated knockdown of MDM2(si-MDM2). The reversal effects of MDM2 overexpression on DHA′s inhibition on the proliferation and migration of A549 and PC9 cells were observed. Results: DHA inhibited the proliferation of A549 and PC9 cells in a dose⁃ and time⁃dependent manner,with IC50 values of 30. 57 and 78. 61 μmol/L , respectively. Compared with the Control group , A549 and PC9 cells had significantly decreased colony formation (both P < 0. 01) and migration (both P < 0. 01) upon treatment with DHA. Moreover, DHA significantly inhibited the protein expression levels of MDM2 and N ⁃cadherin in A549 and PC9 cells , and upregulated the expression of E ⁃cadherin protein (both P < 0. 05) . Compared with si⁃Control ,si⁃MDM2 significantly inhibited the protein levels of MDM2 and N ⁃cadherin in A549 and PC9 cells , and upregulat⁃(both P < 0. 01) of both cells. After overexpression of MDM2 in A549 and PC9 cells , the proliferation and migra⁃ tion ability were significantly enhanced (both P < 0. 05) , and the inhibitory effects of DHA were partially reversed by MDM2 overexpression (both P < 0. 05) . Conclusion DHA effectively inhibits the proliferation and migration of lung adenocarcinoma cells , and its mechanism is associated with the suppression of MDM2.

Objective : To investigate the effects of microRNA-29a(miR-29a) in mediating the regulation of dihydroartemisinin(DHA) on the immune checkpoint molecule B7H3 in lung adenocarcinoma(LUAD). Methods: The expression level and prognostic significance of B7H3 in LUAD were analyzed by public database. Small interfering RNA(siRNA) was used to knock down B7H3 in LUAD cell lines A549 and HCC827, and cell proliferation was detected by CCK-8 method. A549 and HCC827 cells were treated with gradient concentrations of DHA(0, 5, 10, 25, 50, 100 μmol/L) for 48 h, and the half maximal inhibitory concentrate(IC50) was calculated. A549 and HCC827 cells were treated with IC50concentration of DHA for 1, 2 and 3 days, and the cell proliferation was detected by CCK-8 method. A549 and HCC827 cells were transfected with miR-29a inhibitor. After DHA treatment, the expression level of miR-29a was detected by RT-qPCR, and the expression level of B7H3 was detected by Western blot. Results : B7H3 was overexpressed in LUAD and associated with poor prognosis. After knocking down of B7H3, the proliferation ability of A549 and HCC827 cells significantly decreased(allP<0.001). DHA inhibited the proliferation of A549 and HCC827 cells in both dose-and time-dependent manners, with IC50values of 30.16 μmol/L and 7.50 μmol/L, respectively. DHA up-regulated the expression of miR-29a in A549 and HCC827 cells(P<0.001,P<0.01), and down-regulated the expression of B7H3 in both cell lines(P<0.01,P<0.001). After transfection of miR-29a inhibitor into A549 and HCC827 cells, the expression of B7H3 was up-regulated, and the down-regulation of B7H3 by DHA was partially reversed. Conclusion miR-29a mediates the molecular regulation of DHA on B7H3 in LUAD.

Objective:To evaluate the effect of ultrasound-guided internal branch block of superior laryngeal nerve on stress response during endotracheal catheter indwelling in patients undergoing uvulopalatopharyngoplasty (UPPP).Methods:A total of 80 patients with severe obstructive sleep apnea syndrome requiring elective UPPP from the Hunan Provincial People′s Hospital from January 2020 to December 2021 were retrospectively selected and divided into nerve block group (group B) and dexmedetomidine group (group D). Patients in group B and D received general anesthesia. Patients in the group B received bilateral internal branch block of superior laryngeal nerve under ultrasound guidance before postoperative recovery. Patients in the group D received dexmedetomidine intravenously before the end of surgery.

ObjectiveTo analyze the long-term trends of the disease burden of diabetes attributed to metabolic factors in China from 1990 to 2019, and provide scientific recommendations for diabetes prevention and control in China. MethodsDescriptive analysis was conducted on the disease burden data of diabetes attributed to metabolic factors in China from 1990 to 2019, obtained from GBD 2019, encompassing death form diabetes, disability-adjusted life years (DALY), years of life lost (YLL), and years lived with disability (YLD). Joinpoint regression models were employed to analyze the long-term trends in mortality and DALY rates. Furthermore, the study examined the impact of two metabolic risk factors, high fasting plasma glucose (FPG) levels and high body mass index (BMI) levels, on the disease burden of diabetes. ResultsFrom 1990 to 2019, the overall standardized mortality and DALY rates attributed to metabolic factors for diabetes in the general population in China showed an upward trend, with both average annual percent changes (AAPCs) of 0.1% in the total population. The trend was upward in males with AAPCs of 0.9% and 0.6%, while it was downward in females with AAPCs of -0.4% and -0.3%. As age increased, the disease burden of diabetes attributed to metabolic factors showed an upward trend, with high FPG and high BMI ranking as the top two attributing risk factors. The disease burden of diabetes attributed to metabolic factors was higher in Chinese males than females. ConclusionThe disease burden of diabetes attributed to metabolic factors is increasing among the overall population and particularly among males, while the burden for female is declining. There is a need to increase intervention efforts for males aged 65 and above, provide scientific guidance on residents’ diet and lifestyle habits, and control blood glucose and body weight.

Objective:To investigate the association between time in target range and risk of vertebral fracture in patients with type 2 diabetes.Methods:The clinical data of 1 032 patients with type 2 diabetes who were hospitalized in endocrine department of Henan Provincial People′s Hospital from June 2017 to July 2021 were collected. Among which 632 patients were included into final analysis. The diabetes-specific risk score for vertebral fracture was used to assess the risk of vertebral fracture. Multivariate linear regression analysis was used to test the association between time in target range and risk score of vertebral fracture. Risk score≥9 was defined as increased risk of vertebral fracture. Multivariate logistic regression was used to estimate the association between time in target range and risk of vertebral fracture. Results:Among the included patients, mean age was(55.0±12.4) years and the percent of male was 72.5%. The mean course of diabetes was(9.4±8.0) years, and mean score of risk of vertebral fracture was 5.6±4.3. Time in target range was negatively correlated with risk score of vertebral fracture( P for trend <0.001), which was independent of potential confounders and continuous glucose monitoring parameters. The included patients were divided into four groups based on quartiles of time in target range. Multivariate logistic regression indicated that the risk of vertebral fracture in the first quartile of time in target range was 4.6 times higherthanthatinthe4thquartile, and the significance remained adjusted for potential confounders, s, CV, or meanamplitudeofglycemicexcursions(MAGE), respectively. Conclusion:Timein target rangewasnegativelycorrelatedwithriskscoreofvertebralfracturein patient with type 2 diabetes. Low time in range level was an independent risk factor for increased risk of vertebral fracture.
