Objective:To investigate the association of serum γ-glutamyltransferase (GGT) with stroke severity and outcome in patients with acute ischemic stroke (AIS).Methods:Patients with AIS admitted to the Department of Neurology, Hefei Second People's Hospital (Guangde Road Branch) from January 2023 to December 2023 were included retrospectively. According to the baseline National Institutes of Health Stroke Scale score, the patients were divided into mild stroke group (≤8) and moderate to severe stroke group (>8); According to the modified Rankin Scale score at 3 months after onset, the patients were divided into a good outcome group (0-2) and a poor outcome group (>2). Multivariate logistic regression analysis was used to determine the independent influencing factors of stroke severity and outcome, and the receiver operating characteristic (ROC) curve was used to evaluate the predictive value of serum GGT for poor outcome. Results:A total of 136 patients with AIS were included, with 42 patients (30.88%) in the mild stroke group and 94 (69.12%) in the moderate to severe stroke group; 80 patients (58.82%) in the good outcome group and 56 (41.18%) in the poor outcome group. Multivariate logistic regression analysis showed that higher serum GGT was an independent related factor for moderate to severe stroke (odds ratio [ OR] 1.075, 95% confidence interval [ CI] 1.017-1.135; P<0.05) and poor outcome ( OR 1.131, 95% CI 1.069-1.197; P<0.05). The ROC curve analysis showed that the area under the curve for predicting poor outcome by serum GGT was 0.820 (95% CI 0.747-0.892). Conclusion:Serum GGT is significantly correlated with the severity of stroke in patients with AIS, and has certain predictive value for poor short-term outcome.

The research of damp-heat syndrome in modern TCM mainly focuses on inflammatory response, water metabolism, lipid metabolism, hemorheology, intestinal flora and so on. Modern omics techniques such as metabolomics and genomics provide a new perspective for the exploration of the micro-mechanism of damp-heat syndrome. The study found that the abnormal expression of aquaporin is closely related to the formation of "dampness" in damp-heat syndrome, and the release of inflammatory factors reflects the pathological characteristics of "heat". Damp-heat syndrome is often accompanied by dyslipidemia, hemorheological changes and intestinal flora imbalance, showing characteristic changes in urine, blood and saliva metabolomics, and there are differences in gene expression between damp-heat constitution and gentleness constitution. In the future, the pertinence and systematicness of research should be strengthened, the relationship between indicators should be deeply explored, build a biomarker system should be built, the immune-metabolic regulation mechanism should be explored, the multi-target mechanism of heat-clearing and dampness-removing Chinese materia medica should be clarified to further improve the damp-heat syndrome system, and provide theoretical support for clinical treatment.

ObjectiveTo investigate the effects of Guizhi Jia Longgu Mulitang on the expression difference of interleukin-10 （IL-10） and tumor necrosis factor -α （TNF-α） in related organs of insomnia rats with sensory dysfunction dominated by lung and study the mechanism of Guizhi Jia Longgu Mulitang in improving insomnia. MethodSD rats were randomly divided into the blank group， model group， western medicine group， and traditional Chinese medicine （TCM） group， with 10 rats in each group. The rats were deprived of sleep by shallow water environment method in a long platform， and the modeling lasted for 42 d. The blank group and model group were given 0.05 mL·kg^-1 normal saline by gavage， and the western medicine group and TCM group were given drugs during modeling. To be specific， the western medicine group was given 0.105 mg·kg^-1 dexzopiclone tablet by gavage， while the TCM group was given 7 600 mg·kg^-1 Guizhi Jia Longgu Mulitang by gavage， both lasting for 28 days. After successful modeling， the Morris water maze experiment was performed on the 42nd day to detect the motion and spatial memory ability of rats. The levels of IL-10 and TNF-α in serum were detected by enzyme-linked immunosorbent assay （ELISA）. The protein expression of IL-10 and TNF-α in the lung and brain tissue of rats was detected by Western blot. The levels of IL-10 and TNF-α in the lung and brain tissue of rats were detected by immunohistochemistry. ResultCompared with the blank group， the sleep stages non-rapid eye movement ( NREM ) and rapid eye movement ( REM ) of the model group were significantly shortened （P<0.5， P<0.01）， and the wake stage was significantly increased （P<0.01）. The total time and distance of platform exploration were significantly increased （P<0.01）. In the target quadrant （the third quadrant）， the percentage of exploration time and the times of crossing the platform were significantly decreased （P<0.01）. ELISA results showed that the serum IL-10 level was significantly decreased （P<0.01）， and TNF-α level was significantly increased （P<0.01）. The results of Western blot showed that the protein expression of IL-10 in brain and lung tissue of rats was significantly decreased （P<0.01）， and the protein expression of TNF-α was significantly increased （P<0.01）. The results of immunohistochemistry showed that the expression of IL-10 in the brain and lung tissue of rats was significantly decreased （P<0.01）， and that of TNF-α was significantly increased （P<0.01）. Compared with the model group， the NREM stage and REM stage of the western medicine group and the TCM group were significantly increased （P<0.5， P<0.01）， and the wake stage was shortened （P<0.5）. The total time and distance of platform exploration were significantly decreased （P<0.01）. In the target quadrant （the third quadrant）， the percentage of exploration time and the times of crossing the platform were significantly increased （P<0.05， P<0.01）. The serum IL-10 level was significantly increased （P<0.01）， and the serum TNF-α level was significantly decreased according to the ELISA results （P<0.01）. The results of Western blot showed that the protein expression of IL-10 in brain tissue and lung tissue was significantly increased （P<0.01）， and the protein expression of TNF-α was significantly decreased （P<0.01）. The results of immunohistochemistry showed that the expression of IL-10 in brain tissue and lung tissue was significantly increased （P<0.05， P<0.01）， and the expression of TNF-α was significantly decreased （P<0.05， P<0.01）. ConclusionGuizhi Jia Longgu Mulitang can improve the expression of IL-10 and TNF-α in brain and lung tissue of insomnia rats with sensory dysfunction dominated by lung， prolong sleep time， and then improve insomnia. The mechanism may be related to improving the expression level of inflammatory factors.

Hyperlipidaemic rats were randomly divided into a model group,a total flavonoids from echinops latifolius tausch(TFET)high,medium and low dose group,and a positive control group;meanwhile,healthy rats were selected as a blank control group.The rats in each group were dosed with the corresponding concentrations of TFET,simvastatin and distilled water for 45 consecutive days,and were tested for relevant lipid biochemical indexes,antioxidant indexes and PPARα path-way-related gene expression.The results showed that high-dose TFET could reduce the concentra-tions of TC,TG and LDL-C and increase the concentration of HDL-C very significantly;medium-dose TFET could reduce the concentrations of TC and TG very significantly and reduce the con-centration of LDL-C significantly;and low-dose TFET could reduce the concentrations of TC and LDL-C significantly.High,medium and low doses of TFET can extremely significantly reduce in-crease SOD activity;high and medium doses of TFET can extremely significantly reduce MDA content;high dose of TFET can extremely significantly increase T-AOC activity.The high dose of TFET could extremely significantly increase the expression of PPARα,CYP7A1 and CPT-1 genes in rat liver;the medium dose of TFET could extremely significantly increase the expression of CYP7A1 and CPT-1 genes,and could significantly increase the expression of PPARα gene;the low dose of TFET could extremely significantly increase the expression of CYP7A1 gene,and signifi-cantly increase the CPT-1 gene expression.The results suggest that TFET has antioxidant and lip-id-lowering effects on hyperlipidaemic rats,and its mechanism may be related to the activation of PPARα and its downstream related genes to promote fatty acid β-oxidation.

Objective To explore the mechanism of Yanggan Anhun Decoction in the treatment of insomnia with liver failing in storing soul type based on network pharmacological methods;To perform animal model validation.Methods The drug components and targets of Yanggan Anhun Decoction were retrieved from TCMSP and BATMAN-TCM databases,and the targets of insomnia with liver failure store soul type were retrieved from GeneCards,NCBI and DisGeNET databases.By constructing a protein-protein interaction(PPI)network and analyzing GO and KEGG pathway enrichment,the signaling pathway of Yanggan Anxin Decoction in treating insomnia with liver failing in storing soul type was determined,and molecular docking was performed between the main active components and core targets.24 SD rats were randomly divided into normal group,model group,TCM group and Western medicine group,with 6 rats in each group.The insomnia model rats with liver failing in storing soul type were constructed by compound multi factor stimulation method,and were given drugs for 14 days.The cognitive memory ability of rats were detected by Morris water maze test;Nissl staining was used to observe the morphology and number of Nissl bodies in the hypothalamus of rats;serum IL-6 and TNF-α contents were detected by ELISA;IL-6 and TNF-α in hypothalamus and Bcl-2,Bax protein expression levels of rats were detected by immunohistochemistry.The relative expressions of p38 MAPK,p-p38 MAPK,Bcl-2,Bax proteins in the hypothalamus of rats were detected by Western blot.Results A total of 301 active components,321 potential targets and 92 key targets were obtained.Key active components such as quercetin,kaempferol,luteolin,wogonin,sebiferic acid and β-sitosterol,as well as core targets such as MAPK,IL6 and TNF were obtained after screening.The key targets mainly focused on various signaling pathways such as TNF signaling pathway,MAPK signaling pathway,PI3K-Akt signaling pathway,dopaminergic synapse,and neuroactive ligand-receptor interaction,etc.Kaempferol,quercetin,digitonin and other flavonoids had good binding activity and stability with MAPK,TNF,IL6 and showed good affinity.The results of animal experiments showed that,compared with the normal group,the cognitive memory ability of the model group decreased(P<0.05),Nissl bodies were stained shallowly,the density was lower,the cell body was shrunk and deformed,the cell nucleus was broken and dissolved,and the serum and hypothalamic IL-6,TNF-α increased(P<0.05),the expressions of p-p38 MAPK/p38 MAPK and Bax in hypothalamus increased(P<0.05),while the expressions of Bcl-2 and Bcl-2/Bax decreased(P<0.05);compared with the model group,the cognitive memory ability of the TCM group and the Western medicine group were improved,the number of Nissl bodies significantly increased,the nucleus was clear,the cell body shrinkage and deformation were improved(P<0.05),the levels of IL-6 and TNF-α in serum and hypothalamus decreased(P<0.05),while the expressions of p-p38 MAPK/p38 MAPK and Bax decreased,and the expression of Bcl-2 and Bcl-2/Bax increased(P<0.05).Conclusion Yanggan Anhun Decoction may play its effects in treating insomnia with liver failing in storing soul type by regulating MAPK,TNF,IL6,Bcl-2,Bax and other core targets,and interfering with p38MAPK signaling pathway.

ObjectiveTo study the medication rules of Professor. WANG Xingkuan and inherit his academic experience in the treatment of chest stuffiness and pain with the aid of the Traditional Chinese Medicine Inheritance Computing Platform V3.0 （TCMICS V3.0）. MethodThe original medical records of patients with angina pectoris in coronary heart disease （CHD） diagnosed and treated by Prof. WANG in the outpatient department of Hunan University of Chinese Medicine from 2017 to 2020 were collected and entered into the TCMICS V3.0. The rules of prescriptions and drugs were analyzed by the software. ResultA total of 1 044 prescriptions of Prof. WANG for the treatment of chest stuffiness and pain were collected. Most of the drugs were sweet and bitter in flavor and mainly acted on the lung meridian， followed by heart， spleen， liver， stomach， and kidney meridians. Among the prescriptions， Shengmaisan was the most commonly used classic prescription， and Xintongling No. Ⅲ was the top experienced prescription. High-frequency drugs mainly included Ophiopogonis Radix， Pinelliae Rhizoma， Salviae Miltiorrhizae Radix et Rhizoma， Trichosanthis Pericarpium， Coptidis Rhizoma， Schisandrae Chinensis Fructus， and Bupleuri Radix. The common doses of drugs were 3， 5， 10， and 15 g. The analysis of formulation rules revealed 129 combinations of common drugs， 58 combinations with confidence > 0.99， and the core drugs of common syndromes. Six core drug combinations were obtained by drug clustering. ConclusionProfessor WANG treats chest stuffiness and pain based on syndrome differentiation following the principles of benefiting Qi， nourishing Yin， eliminating phlegm， resolving stasis， soothing liver， and promoting bile secretion， reflecting his academic idea of "regulation of multiple organs and comprehensive treatment". The core prescriptions can be used for reference by clinical practitioners， but further clinical and experimental studies are still needed to verify their efficacy.

Objective:To explore our self-designed classification system of irreducible intertrochanteric fractures based on reduction stage and bone block position and to evaluate the reduction techniques guided by the classification system.Methods:A retrospective study was conducted to analyze the data of 115 patients with irreducible intertrochanteric fracture who had been admitted to Department of Orthopedics, Beijing Hospital from September 2014 to November 2022. There were 24 males and 91 females with a mean age of (80.9±11.0) years. The reduction for the fractures was divided into a diaphysis reduction stage (Phase Ⅰ) and a cortical reduction stage (Phase Ⅱ). Based on the relative positions of the intraoperative bone blocks, Phase Ⅰ was divided into an anterior and posterior interlocking type (Phase Ⅰa) and a distal bone block sinking displacement type (Phase Ⅰb) while Phase Ⅱ into a proximal lifting type (Phase Ⅱa), a posterior angulation type (Phase Ⅱb), a positive support type (Phase Ⅱc), and a negative support type (Phase Ⅱd). Depending on the difficulties encountered in different reduction stages, corresponding close reduction strategies (such as top rod support, percutaneous prying, and Joystick technique) were adopted to restore the proximal femoral neck shaft angle, anteversion angle, anterior medial cortex, and length of the affected limb before fixation with intramedullary nails. Recorded were the patient's surgical time, intraoperative bleeding, quality of postoperative reduction, fracture union time, and complications.Results:The surgical time for this group of patients was 70.0(60.0, 92.0) minutes, and the intraoperative blood loss 200.0 (170.0, 200.0) mL. According to the standards by Baumgaertner et al., the quality of postoperative reduction was evaluated as excellent in 103 cases and as good in 12 cases, with an excellent and good rate of 100.0% (115/115). Of the 115 patients, 86 were followed up for more than 6 months to reveal fracture union in all after a duration of 6.0 (4.0, 8.0) months. One patient died of an acute cardiovascular event in the hospital 5 days after surgery. Two patients lost their mobility within 3 months after surgery due to acute cerebral infarction. There was no internal fixation failure requiring secondary surgery or no incision infection.Conclusion:Guided by our self-designed classification system of irreducible intertrochanteric fractures based on the intraoperative reduction stage and the relative position of bone block, real time intraoperative fluoroscopy images can be used to effectively clarify the difficulty of fracture reduction in stages so that corresponding reduction strategies can be adopted, leading to fine clinical efficacy.

BACKGROUND: The HELIOS stent is a sirolimus-eluting stent with a biodegradable polymer and titanium oxide film as the tie-layer. The study aimed to evaluate the safety and efficacy of HELIOS stent in a real-world setting. METHODS: The HELIOS registry is a prospective, multicenter, cohort study conducted at 38 centers across China between November 2018 and December 2019. A total of 3060 consecutive patients were enrolled after application of minimal inclusion and exclusion criteria. The primary endpoint was target lesion failure (TLF), defined as a composite of cardiac death, non-fatal target vessel myocardial infarction (MI), and clinically indicated target lesion revascularization (TLR) at 1-year follow-up. Kaplan-Meier methods were used to estimate the cumulative incidence of clinical events and construct survival curves. RESULTS: A total of 2998 (98.0%) patients completed the 1-year follow-up. The 1-year incidence of TLF was 3.10% (94/2998, 95% closed interval: 2.54-3.78%). The rates of cardiac death, non-fatal target vessel MI and clinically indicated TLR were 2.33% (70/2998), 0.20% (6/2998), and 0.70% (21/2998), respectively. The rate of stent thrombosis was 0.33% (10/2998). Age ≥60 years, diabetes mellitus, family history of coronary artery disease, acute myocardial infarction at admission, and device success were independent predictors of TLF at 1 year. CONCLUSION: The 1-year incidence rates of TLF and stent thrombosis were 3.10% and 0.33%, respectively, in patients treated with HELIOS stents. Our results provide clinical evidence for interventional cardiologists and policymakers to evaluate HELIOS stent. CLINICAL TRIAL REGISTRATION ClinicalTrials.gov, NCT03916432.
