Objective:
To explore the plasma metabonomic characteristics of patients with type 2 diabetes mellitus and turbid toxin accumulation syndrome.
Methods:
One hundred and three patients with type 2 diabetes mellitus and turbid toxin accumulation syndrome were enrolled from November 2023 to February 2024 in the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine and 54 healthy individuals were recruited. The general data of the two groups were analyzed, and the plasma metabolite content was detected using ultra-high performance liquid chromatography-Orbitrap mass spectrometry. Construct an orthogonal partial least squares discriminant analysis model to screen metabolites with significant intergroup changes. The variable importance in projection≥ 1, |log2FC|>1, and P<0.05 were used as the criteria for the screening of differential metabolites. Annotate differential metabolites using internal databases and the human metabolome database, and perform pathway analysis using MetaboAnalyst website.
Results:
There was no statistically significant difference in gender and age between the two groups.Seventeen potential differential metabolites were identified. The D-4′-phosphopantothenate, 2, 6-dichloroindophenol, 4-methylphenol, hypoxanthine, 11, 12-epoxyeicosatrienoic acids, oleamide, 3-phenyllactic acid contents were higher in patients with type 2 diabetes mellitus and turbid toxin accumulation syndrome than in healthy individuals(P<0.05); 3-anisic acid, 3-iodo-octadecanoic acid, mebendazole, β-alanine, citric acid, trans-aconitic acid, geranyl diphosphate, lysophosphatidylcholine(18∶2), phosphatidylethanolamine(18∶1), and caprolactam contents were lower in patients with type 2 diabetes mellitus and turbid toxin accumulation syndrome than in healthy individuals(P<0.05). Ten metabolic pathways were identified, including the key metabolic pantothenate and coenzyme A biosynthesis pathways.
Conclusion
Metabolic differences were observed between patients with type 2 diabetes mellitus and turbid toxin accumulation syndrome and healthy individuals, and the underlying mechanism may involve the pantothenate and coenzyme A biosynthesis pathways, jointly mediated by D-4′-phosphopantothenate and β-alanine.

Along with the change in lifestyle and diet, diabetes mellitus with hyperlipidemia has been a major risk and death factor for cardiovascular disease with the increasing incidence of diabetes mellitus with hyperlipidemia year by year. In order to promote and make full use of unique characteristics and advantages of TCM, the guidance writing group adopted the pattern of combination with disease and syndrome to make a standardized approach to diagnosis and treatment based on emphasis on diagnosis and treatment. Guidelines for the Diagnosis and Treatment of Diabetes Mellitus with Hyperlipidemia Combined with Disease and Syndrome (hereinafter referred to as " the Guideline") was published in the World Chinese Medicine in August, 2021. Based on the pattern of combination with disease and syndrome, the Guideline highlights the significant characteristics, such as: precise diagnosis and treatment by combined with disease and syndrome, updating criteria, rehabilitation diet therapy and exercise and following the principles which include but not limited to evidence-based medicine. According to the evidence of evidence-based medicine and expert consensus, the Guideline gives recommendations for diagnosis, treatment and rehabilitation of diabetes mellitus with hyperlipidemia. In the article, the main contents and characteristics of the new guideline were interpreted in order to provide concise and practical guidance for clinicians and promote the clinical popularization and application of the Guideline.

BACKGROUND:
Catheter ablation is effective in restoring sinus rhythm and left atrial appendage closure (LAAC) is increasingly used for stroke prevention in patients with atrial fibrillation (AF). We aimed to observe the feasibility and safety of performing AF ablation and LAAC in a single (one-stop) procedure.
METHODS:
Consecutive AF patients who underwent the combined procedure of AF ablation and LAAC with WATCHMAN device between March 2017 and September 2018 were prospectively enrolled. Baseline and intra-procedural parameters were evaluated. Three-month and subsequent 1-year follow-up were performed in all and earlier-enrolled subjects, respectively.
RESULTS:
A total of 178 AF patients (94 males, 68.9 ± 8.1 years) underwent the one-stop procedure with CHA2DS2-VASc score 3.3 ± 1.5 and HAS-BLED score 1.6 ± 1.0, respectively. Pulmonary vein isolation was achieved in all patients while additional linear ablation was applied if the operator deemed necessary, yielding immediate ablation success rate of 98.9% (176/178). In the subsequent LAAC, satisfactory seal (residual leak <5 mm) was achieved in all patients. One stroke and four cardiac perforations occurred peri-operatively. At 3-month follow-up, sinus rhythm and satisfactory seal were maintained in 153/178 (86.0%) and 178/178 (100%) patients, respectively. One stroke and one delayed cardiac tamponade occurred, while no device-related thrombus or device migration was observed. During the 1-year follow-up for the earlier enrolled subjects, 52/72 (72.2%) of the patients maintained sinus rhythm. There was no stroke or systemic embolism observed.
CONCLUSION
Combining catheter ablation and LAAC in a single procedure can be successfully and safely performed in non-valvular AF patients of Chinese population.

Objective:To investigate the protective effect of Wutou Chishizhi Wan on myocardial ischemia reperfusion injury (MIRI) in rats, and observe its effect on such mechanisms as coagulation function, vascular endothelial cells and oxidative stress in rats. Method:A total of 40 SD rats were randomly divided into normal group, model group, positive drug group (Urokinase group) and Wutou Chishizhi Wan group, with 10 rats in each group. Except for the normal group, rat myocardial ischemia-reperfusion injury models were established. The changes of heart rate (HR) at 10 min before ischemia, 30 min after ischemia and 30, 60, 120 min (T0,T1,T2,T3,T4), and the change of electrocardiogram (ECG) J point after modeling in rats were observed. The pathological changes of rat myocardial tissue were observed by hematoxylin-eosin (HE) staining. The changes of four indexes of coagulation [prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen content decreased significantly (FIB)] in rats were observed. The contents of endothelin-1 (ET-1), thromboxane A2 (TXA2) and prostacyclin (PGI2) in serum and myocardium levels of superoxide dismutase (SOD), malondialdehyde (MDA) and glutathione peroxidase (GSH-Px) of MIRI rats were observed. Western blot assay was used for the detection of oxidative stress protein Keap1 and transcription factor-E2-related factor (Nrf2) expression levels in rat myocardial tissue. Result:Compared with the normal group, the ECG of MIRI rats showed significant myocardial ischemic injury-like changes, ST segment was significantly elevated, J point was significantly increased, and the incidences of HR in T1, T2, T3 and T4 were significantly reduced (

OBJECTIVE:
To detect the expression of miR-99a-5p in myelodysplastic syndrome (MDS), to predict the target genes and to analyze its function by using bioinformatics.
METHODS:
The expression levels of bone marrow miR-99a-5p in MDS patients were detected by qRT-PCR, and the correlation of miR-99a-5p expression with clinical pathological characteristics, percentage of marrow blasts , chromosome karyotype and peripheral blood hemogram were analyzed. The target genes of miR-99a-5p were predicted by Targetscan, Miranda and Microcosm, and the intersection of the predicted results of 3 softwares was used as a potential target gene for miR-99a-5p.
RESULTS:
The expression level of bone marrow miR-99a-5p in MDS patients was significantly higher than that of healthy controls (P<0.01); According to the prognostic score of IPSS, MDS patients were divided into relatively low risk group (including low risk group and intermediate risk group 1) and relatively high risk group (including intermediate risk group 2 and high risk group). Analysis showed that the expression level of bone marrow miR-99a-5p in relatively low risk group was 2.40 times higher than that in healthy control group (P<0.01), the expression level of bone marrow miR-99a-5p in relatively high risk group was 6.66 times higher than that in healthy control group (P<0.01), the expression level of miR-99a-5p in relatively high risk group was 2.80 times higher than that in the relatively low risk group ( P<0.01) ; the expression level of bone marrow miR-99a-5p in t-MDS group was 6.35 times higher than that in healthy control group (P<0.001). There was a significant positive correlation between the expression level of miR-99a-5p and the percentage of marrow blasts (P<0.01), but the expression of miR-99a-5p did not correlate with chromosome karyotype and peripheral blood hemogram; In this study it was obtained that ST5 might participate in pathological mechanism of MDS by bioinformatic analyses and references.
CONCLUSION
The expression levels of miR-99a-5p is up-regulated in MDS patients, and its expression showed a rising tendency which may be involved in the pathogenesis of MDS by regulating target gene ST5.

BACKGROUND:
The current upper-frequency cutoff of 150 Hz sometimes causes loss of pacemaker spike and misdiagnosis. We hypothesized that low-pass filter (LPF) other than 150 Hz could improve the detection of pacemaker spike. This study aimed to examine the effect of different LPF on pacemaker spike detection in remote and bedside electrocardiogram (ECG).
METHODS:
Patients with permanent pacemaker implantation were included during routine follow-up. Standard 12-lead ECGs at 6 different upper-frequency cutoff (40, 100, 150, 200, 300, and 400 Hz) were collected. All ECGs were then transmitted to the remote clinic center. Ventricular and atrial pacing were analyzed by 2 independent medical practitioners.
RESULTS:
A total of 88 patients' ECGs were analyzed (mean age 73.8 ± 10.2 years and 85 with dual-chamber pacemakers). About 75.3% (64/85) of patients were diagnosed as atrial pacing by pacemaker programming. Among 6 different upper-frequency cutoff, the 300 Hz turned out to perform best in detecting atrial-paced spike (area under the curve [AUC] = 0.73, 95% confidence interval [CI]: 0.61-0.84 vs. 0.56, 95% CI: 0.61-0.84 at 150 Hz; P = 0.002) on bedside ECGs. Using programming as the golden standard, the 300 Hz LPF has a sensitivity of 59.4%, specificity of 85.7%, positive predictive value of 92.7% and negative predictive value of 40.9% on bedside ECGs. As for the ventricular pacing, the 300 Hz LPF also had a higher accuracy (AUC = 0.93; 95% CI = 0.84-1.00) than that at 150 Hz (AUC = 0.86; 95% CI: 0.77-0.94; P < 0.001) in detecting ventricular-paced spike on bedside ECGs. The results of remote ECGs were similar with bedside ECGs.
CONCLUSIONS
A filter of 300 Hz cutoff may be recommended for ECG spike detection. With the recommended parameter, remote ECG can perform as well as bedside ECG.

OBJECTIVE: The purposes of this study were to measure the orthodontic forces generated by thermoplastic aligners and investigate the possible influences of different activations for lingual bodily movements on orthodontic forces, and their attenuation. METHODS: Thermoplastic material of 1.0-mm in thickness was used to manufacture aligners for 0.2, 0.3, 0.4, 0.5, and 0.6 mm activations for lingual bodily movements of the maxillary central incisor. The orthodontic force in the lingual direction delivered by the thermoplastic aligners was measured using a micro-stress sensor system for the invisible orthodontic technique, and was monitored for 2 weeks. RESULTS: Orthodontic force increased with the amount of activation of the aligner in the initial measurements. The attenuation speed in the 0.6 mm group was faster than that of the other groups (p < 0.05). All aligners demonstrated rapid relaxation in the first 8 hours, which then decreased slowly and plateaued on day 4 or 5. CONCLUSIONS: The amount of activation had a substantial influence on the orthodontic force imparted by the aligners. The results suggest that the activation of lingual bodily movement of the maxillary central incisor should not exceed 0.5 mm. The initial 4 or 5 days is important with respect to orthodontic treatment incorporating an aligner.

OBJECTIVETo investigate the expression of miR-550a-5p in bone marrow of patients with myelodysplastic syndrome (MDS), and to predict its target genes and function by bioinformatics analyses, so as to provide the evidence to furthre explore the role of miR-550a-5p and its target genes in pathogenesis of MDS.
METHODSReal-time PCR was used to detect the expression of miR-550a-5p in 54 MDS patients, 16 acute myeloid leukemia transformed from MDS (sfAML) and 19 healthy controls, and the correlation between the expression of miR-550a-5p and clinical pathologic characteristics of MDS, including chromosome, percentage of marrow blasts, absolute neutrophil count, platelet count and hemoglobin levels were analyzed. The sequence of miR-550 was searched in miRBase database. Target genes of miR-550a-5p were predicted by Microcosm,Miranda and Targetscan, and the predective results were collected, then the enrichment analyses of target gene function(GO) and signalling pathway(pathway of miR-550a-5p) were carried out by using gene ontology darabase and KEGG database.
RESULTSThe expression of miR-550a-5p in bone marrow of all MDS patients was higher than that in controls: the expression level of miR-550a-5p in low risk MDS and middl risk 1 MDS was 1.7 times of controls (P=1.23×10); the expression of miR-550a-5p in midde risk 2 MDS and high risk MDS was 1.9 times of controls (P=1.20×10); the expression of miR-550a-5p in tAML was 2.0 times of controls (P=5.61×10). The miR-550a-5p expression level was up-regulated gradually with the enhancement of disease risk of MDS, but there was no correlation between the expression level of miR-550a-5p and clinical pathologic characteristics of MDS(chromosome: Normal: 1.11±0.19, Abnormal:1.26±0.15, P>0.05; Percentage of Marrow Blasts: r=0.29,P=0.07; absolute neutrophil count: r=-0.02,P=0.89; hemoglobin level: r=0.09,P=0.57; platelet count: r=0.25,P=0.08). The sequence of miR-550 was conservative among different species, and the prediced results indicated that there were 19 target genes in intersection. The functions of target genes were enriched in regulation of stress-activated cascade, MAPK pathway, regulation of muscle organ development, regulation of protein homodimerization activity and other biological processes; they participated in some molecular functions including enzyme activity, combination processes of some molecules as protein, cAMP and domain existed in cell junction, synapse, coated vesicle, dendrite and other cellular components. Two of them-PDLIM2 and PSME1 were selected which might play a role in pathologic mechanism of MDS regulated by miR-550a-5p.
CONCLUSIONThe expression of miR-550a-5p in bone marrow of MDS patients increases specifically, and miR-550a-5p may play a role in the pathogenesis of MDS through regulation of target genes, PDLIM2 and PSME1.

BACKGROUNDHepatic alveolar echinococcosis (AE) is a parasitic disease in humans and caused by the Echinococcus multilocularis (Em). Orthotopic liver transplantation (OLT) may be the only effective treatment for end-stage hepatic AE. However, in some AE patients, extrahepatic Em can not be completely eliminated after OLT. We aimed to study whether the immunological changes caused by Em evasion may influence the rejective response.
METHODSRat modles of AE were established by injecting the Em suspension into abdomen of Brown Norway (BN) rats. Three months later, in the experimental group, the liver was transplanted from Lewis (LEW) rats to Em-infected BN rats. In the control group, transplantation was from LEW rats to healthy BN rats. Liver tissue and peripheral blood (PB) samples were collected on days 1, 3, 5, and 7 after OLT. Liver tissue was analyzed after hematoxylin and eosin (H&E) staining; numbers of CD4, CD8, and CD28 on peripheral blood cells were detected by flow cytometry; and expression of the chemokine fractalkine (Fkn) was detected by reverse transcription PCR (RT-PCR). Interleukin-10 (IL-10) was measured in the serum by enzyme-linked immunosorbent assay (ELISA). In every group, eight BN rats were retained for observing survival time.
RESULTSThe survival times of recipients in the experimental group were prolonged compared with those in the control group. The rejective response occurred later and was milder in the experimental group. percentage of CD4, CD8, CD28 T-cells and Fkn mRNA expression were lower in the experimental group. While the serum IL-10 levels were higher in the experimental group than those in the control group.
CONCLUSIONSAcute rejective response after OLT was attenuated in the rats with Em infection, and the recipients` survival time was prolonged. Em may play a role in this process by elevating IL-10 secretion, decreasing the effector T cells, inhibiting the expression of Fkn, which lead to reduce the inflammatory cells infiltration into the liver.
