Objective: To observe the inlfuence of simvastatin combining ezetimibe on blood levels of glucose and lipids in patients of acute coronary syndrome (ACS) with impaired glucose tolerance (IGT).
Methods: A total of 316 patients with ACS and IGT were randomly divided into 2 groups: Treatment group, the patients received simvastatin 20 mg/day with ezetimibe 10 mg/day,n=160 and Control group, the patients received simvastatin 20 mg/day,n=156. All patients were treated for 24 months. Blood levels of total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) were observed at 6, 12 and 24 months of medication; fasting blood glucose (FBG), 2 hour postprandial blood glucose (2hPG), glycosylated hemoglobin (HbA1c) and the number of patients with new onset diabetes were examined at 6 days and 12, 24 months of medication.
Results:①In Treatment group, at 6 months of medication, blood levels of TC (mmol/L) and LDL-C (mmol/L) were (3.5 ± 0.5) and (2.1 ± 0.4) which were both lower than baseline levels (5.2±1.2) and (3.5±0.5),P<0.05; at 12 and 24 months, TC and LDL-C were (3.1 ± 1.0), (1.8 ± 0.6) and (3.0 ± 0.6), (1.8 ± 0.5), TC and LDL-C were consistently decreased, all P<0.05. In Control group, at 6 months of medication, TC and LDL-C were (4.0 ± 0.5) and (2.4 ± 0.5) which were both lower than baseline levels (5.3 ± 0.8) and (3.1 ± 0.4),P<0.05; at 12 and 24 months, TC and LDL-C were (3.8 ± 0.6), (2.3 ± 0.6) and (3.7 ± 0.5), (2.1 ± 0.7), allP<0.05. TC and LDL-C levels in Treatment group were lower than Control group at 6, 12 and 24 months of medication, allP<0.05.②In Treatment group, FBG (mmol/L) levels at 12 and 24 months were similar to 6 days,P>0.05; HbA1c at 12 and 24 months were similar to baseline,P>0.05; 2hPG (mmol/L) level at 24 months was higher than 6 days (9.5 ± 1.1) vs (8.7 ± 1.0),P<0.05; there were 26 patients with new onset diabetes at 24 months after medication. In Control group, 2hPG level at 24 months was higher than 6 days (9.6 ± 0.8) vs (8.7±0.7); there were 25 patients with new onset diabetes at 24 months after medication. The levels of FBG, 2hPG, HbA1c and the number of patients with new onset diabetes were similar between 2 groups, allP>0.05.
Conclusion: Ezetimibe combining simvastatin may better reduce blood lipids, while it had no real effect on blood glucose metabolism in patients with ACS and IGT.

Objective To compare the effect of electro-acupuncture(EA) and warm-needle moxibustion(WNM) on the foot three-dimensional gait time-space parameters and surface electromyography of post-stroke patients with flaccid paralysis. Methods A total of 61 patients were randomly divided into EA group (N=30) and WNM group(N=31). Both groups were given post-stroke conventional treatment, and additionally EA group received EA while WNM group was given WNM. Before treatment and after 2 treatment courses, we detected the foot three-dimensional gait time-space parameters of pace race, stance phase, swing phase, bilateral stance phase, and step length, and surface electromyography parameters of root mean square(RMS), integrated electromyogram (iEMG) and co-contraction ratio(CR) of tibialis anterior muscle and gastrocnemius at the state of maximal isometric voluntary contraction(MIVC). Results(1) After treatment, the foot three-dimensional gait time-space parameters of the two groups were improved in various degrees (P<0.05 or P<0.01 compared with those before treatment) , and the improvement of EA group was superior to that of WNM group (P < 0.05). (2) After treatment, the RMS and iEMG of the gastrocnemius and tibialis anterior muscle as well as CR of dorsal extensor at MIVC state were improved in various degrees (P < 0.05 or P < 0.01 compared with those before treatment) , and the improvement of EA group was superior to that of WNM group(P < 0.05 or P < 0.01). Conclusion WNM exerts better effect on improving the parameters of three-dimensional gait time-space parameters and surface electromyography of post-stroke patients with flaccid paralysis than EA.

Objective To investigate the pathogenesis of white matter damage (WMD) and the effects of xenon intervention on the expression of EphB4 and EphrinB2 mRNA in the brain tissue of neonatal rats.Method Three-day-old SD rat pups (n =96) were randomly assigned into sham group (n =24),model group (n =24),xenon intervention group 1 (n =24) and xenon intervention group 2 (n =24).The WMD model was established by injected of lipopolysaccharide (LPS) 0.05 mg/kg combined with ligation of the right carotid artery for 1 h in the last three groups.Rats in xenon intervention group 1 inhaled 50％ xenon immediately for 3 h after modeling,while rats in xenon intervention group 2 inhaled 50％ xenon for 3 h at 2 h after modeling.After the completion of xenon intervention,6 rat pups in each groups were sacrificed at 0 h,24 h,48 h and 72 h.The pathologic examination of periventricular tissue was conducted with hematoxylin-eosin staining (HE) and the expression of EphB4 and EphrinB2 mRNA was assayed by real-time quantitative polymerase chain reaction (RT-PCR).Statistical analysis was then performed.Result (1)The structure of white matter in model group became loose,band net-like,with significant nucleus pyknosis.The pathological damages in xenon intervention group 1 and 2 were lighter at 24 h,48 h and 72 h than model group,with less karyopycnosis.(2) Compared with the sham group,the expressions of EphB4 and EphrinB2 mRNA at 0 h,24 h,48 h and 72 h were significantly higher in the model group and xenon intervention group 1 and 2 (P ＜ 0.05),except for the EphB4 mRNA in xenon intervention group 1 at 72 h (P ＞ 0.05).The expressions of EphB4 and EphrinB2 mRNA at each time point in xenon intervention group 1 and 2 were decreased significantly than the model group (P ＜ 0.05),except for the EphB4 mRNA in xenon intervention group 2 at 72 h (P ＞ 0.05).However,there was no statistically significant difference on EphB4 and EphrinB2 mRNA between two xenon intervention groups at each time point (P ＞ 0.05).Conclusion The expression of EphB4 and EphrinB2 mRNA are appreciably increased in brain tissue of neonatal rats with WMD,which indicates the reactive angiogenesis.The intervention with xenon may play a neuroprotective role through reducing the expressions of EphB4/EphrinB2 mRNA and angiogenesis,and early intervention may be better.

The endophytic fungus named FSN006 was isolated from the inner bark of Juglans mandshurica. It grew quickly and formed circular colony on PDA plate. The upper side of the colony was white, while the lower side of the colony and the conditioned medium were light yellow as a result of significant yellow pigment substances were produced and secreted by the fungi. Green elliptic conidia appeared when cultured on CMX plate. Based on the morphology identification and ITS sequence, it was clear that this fungus belonged to the Deuteromycotina, HyPhomycetes, Moniliales, Trichoderma longibrachiatum. The conditioned medium of FSN006 showed a high anti-tumor ability against liver cancer cell-HepG2, and reached its IC50 concentration after being diluted 20 times, while the IC50 concentration of curcumine was(11.49 +/- 0.12) mg x L(-1). In addition, there was preeminent selective inhibiting effect against the normal liver cell strain HL-7702 and its caner counter strain HepG2. The inhibiting effect against strain HL-7702 was only one quarter of that against HepG2 at the concentration of IC50. Therefore, the fermentation of FSN006 may provide a possible way to produce anticancer drug with higher efficiency and lower toxicity.

Objective: To evaluate the efficacy and safety of ultrafiltration in patients with heart failure. Methods: One hundred and thirty four cases of patients with heart failure, who hospitalized in our hospital from June 2010 to June 2016 were enrolled in this study. Random serial number was generated using SPSS 22.0 software, patients were then randomly divided into control group and ultrafiltration group with the proportion of 1∶1 (67 cases in each group). Patients in the control group received standard therapy. Patients in the ultrafiltration group received ultrafiltration therapy for 8 hours. Curative effect was evaluated after 8 hours treatment in the control group and after 12 hours in the ultrafiltration group. Following parameters were compared between the two groups: body weight, dyspnea score and 6 minutes walking distance as well as blood pressure, heart rate, Na⁺ , K⁺ , Cl^-, pH, HCO₃^-, Hb, PLT, Cr, BUN levels. Results: (1)Two patients died during run-in process and eventually 132 cases were chosen for final analysis (65 cases in control group and 67 cases in the ultrafiltration group). Gender, age, type of heart failure, dyspnea score, body weight at baseline were similar between the two groups. (2)Post therapy, patients′ body weight decreased obviously, while dyspnea score and 6 minutes walking distance increased significantly in the ultrafiltration group compared to baseline(all P<0.05), and the improvement was significantly greater compared to control group(all P<0.05). (3)The safety index comparison of two groups: blood pressure, heart rate, Na⁺ , K⁺ , Cl^-, pH, HCO₃^-, Hb, PLT, Cr, and BUN were similar between the two groups at baseline and post therapy. Conclusion Ultrafiltration therapy is safe and effective to treat patients with heart failure.

Objective To evaluate the efficacy and safety of a new ultrafiltration device for treating refractory heart failure patients.Methods A total of 52 patients (37 male,age 29-85 (33 ± 44) years)with refractory heart failure were treated using a new ultrafiltration device (FQ-16).Body weight,dyspnea score,oxygen saturation (SatO2),left ventricular ejection fraction (LVEF),BUN,creatinine,electrolytes and blood gas analysis were assessed before and after the treatment.Hypotension event and other main adverse events were recorded.Results Ultrafiltration duration ranged between 8-22 hours.Total ultrafiltration volume was (4 489 ± 1 548) ml.Compared with baseline,patients' body weight decreased from (75.3 ± 8.74) kg to (69.8 ± 8.39) kg (P ＜ 0.01),dyspnea score improved from 2.47 ± 1.55 to 12.87±3.61 (P＜0.01) and SatO2 increased from 91.0 ±6.01 to 96.4 ±2.52 (P ＜0.01) and LVEF increased from (30.0 ± 4.1) ％ to (36.0 ± 4.3) ％ (P ＜ 0.01) after ultrafiltration.Blood creatinine,BUN,electrolytes and blood gas analysis values were similar at baseline and post ultrafiltration.No hypotension event and other main adverse events occurred during the ultrafiltration treatment.Conclusions The novel ultrafiltration device adequately relieved hypervolemia and dyspnea in patients with refractory heart failure and the treatment process is safe in this patient cohort.

AIM: To investigate the relationship between the levels of serum dehydroepiandrosterone(DHEA), erythropoietin(Epo), vasohibin-1(VASH-1)and diabetic retinopathy(DR)in patients with type 2 diabetes mellitus(T2DM). METHODS: Totally 185 T2DM patients(185 eyes)treated in our hospital from April 2021 to March 2024 were selected and divided into T2DM group(102 eyes)and DR group(83 eyes)based on whether retinal lesions occurred. DR patients were divided into nonproliferative DR group(NPDR, 47 cases, 47 eyes)and proliferative DR group(PDR, 36 cases, 36 eyes)based on the severity of their lesions. Fully automatic biochemical analyzer was used to detect serum biochemical indicators. ELISA was applied to detect serum levels of DHEA, Epo, and VASH-1. Pearson correlation was applied to analyze the correlation between serum DHEA, Epo, and VASH-1 levels and the severity of diabetic retinopathy. Logistic regression was applied to analyze the factors affecting the occurrence of DR. ROC curve was applied to analyze the diagnostic value of serum DHEA, Epo, and VASH-1 levels for T2DM combined with DR or PDR.RESULTS: Compared with the T2DM group, the DR group showed significantly increased DM duration, fasting blood glucose, uric acid, creatinine, and Epo, while DHEA and VASH-1 levels were significantly reduced(all P<0.05); Compared with the NPDR group, the PDR group showed a significant decrease in serum DHEA and VASH-1 levels, and a significant increase in Epo levels(all P<0.05); the levels of serum DHEA and VASH-1 were negatively correlated with the severity of DR, while the level of Epo was positively correlated with the severity of DR(all P<0.05); DHEA and VASH-1 were protective factors against DR, while Epo was a risk factor for DR(all P<0.05); the AUC of serum DHEA, Epo, and VASH-1 levels alone and in combination for the diagnosis of T2DM with DR were 0.804, 0.797, 0.805, and 0.903, respectively. The combined diagnostic value was higher than that of single diagnosis(all P<0.05); the AUC of serum DHEA, Epo, and VASH-1 levels alone and in combination for diagnosing PDR were 0.852, 0.850, 0.841, and 0.946, respectively. The value of combined diagnosis was significantly higher than that of individual diagnosis(all P<0.05).CONCLUSION:The levels of serum DHEA and VASH-1 in DR patients are clearly reduced, the level of Epo is clearly increased, and their levels are closely related to the severity of DR patients; therefore, combined detection has higher value for T2DM complicated with DR or PDR.

Klebsiella pneumoniae(K.pneumoniae)is an important pathogen that can cause severe hospital-and community-acquired infections.To systematically investigate its methylation features,we determined the whole-genome sequences of 14 K.pneumoniae strains covering varying serotypes,multilocus sequence types,clonal groups,viscosity/virulence,and drug resistance.Their methy-lomes were further characterized using Pacific Biosciences single-molecule real-time and bisulfite technologies.We identified 15 methylation motifs[13 N6-methyladenine(6mA)and two 5-methylcytosine(5mC)motifs],among which eight were novel.Their corresponding DNA methyl-transferases were also validated.Additionally,we analyzed the genomic distribution of GATC and CCWGG methylation motifs shared by all strains,and identified differential distribution pat-terns of some hemi-/un-methylated GATC motifs,which tend to be located within intergenic regions(IGRs).Specifically,we characterized the in vivo methylation kinetics at single-base resolu-tion on a genome-wide scale by simulating the dynamic processes of replication-mediated passive demethylation and MTase-catalyzed re-methylation.The slow methylation of the GATC motifs in the replication origin(oriC)regions and IGRs implicates the epigenetic regulation of replication initiation and transcription.Our findings illustrate the first comprehensive dynamic methylome map of K.pneumoniae at single-base resolution,and provide a useful reference to better understand epigenetic regulation in this and other bacterial species.
