ELISA technique was employed to determne the concentration of mannose binding lectin (MBL),plasminogen activator inhibitor-1 (PAI 1),and high sensitive ()eactive protein (hs-CRP).hs CRP level m patients with subclinical atherosclerosis was significantly higher (P ＜ 0.01),MBL level was of no significant difference (P＞0.05) ; PAI-1 was significantly higher (P＜0.01) only m those with metabolic syndrome(MS).Taking no account of subclinical atherosclerosis,MBL of diabetic patients with MS was significantly lower while hs-CRP and PNI 1 were signific amlv higher (P ＜ 0.01).Inflammatory faetors MBL,hs-CRP,and PAI-1 involved in the -ube linical atherosclerosis development in the type 2 diabetic patients with MS.

Objective: To optimize the preparation technique for bifonazole suppositories and evaluate the quality.Methods: The appearance, hardness and melting time of suppositories were used as the evaluation indices to optimize the process conditions, such as suppository matrix, drug particle size, injection molding temperature and stirring conditions, etc.The content of bifonazole was determined by HPLC.Results: The best formula was as follows: the matrix was multiplicated monofatty glyceride-36, bifonazole was sieved by 100 mesh sieve and the best molding temperature was 45 ℃.The quality of the prepared suppositories with the above conditions was controllable in the appearance, melting time limit, hardness and content determination, etc.Conclusion: The formula of bifonazole suppositories is reasonable, the preparation process is feasible, and the quality control methods are reliable.

Objective To evaluate the ultrasonic feature and clinical significance of persistent left superior vena cava(PLSVC)in fetal life.Methods Fetal echocardiography was performed in 3368 fetuses.Thirty-one fetuses of PLSVC were confirmed.Results The dilated coronary sinus was observed in 30 of 31 fetuses.Congenital heart defects were presented in 14 of these cases,and extracardiac anomalies were presented in 6 fetuses.Both congenital heart defects and extracardiac anomalies were observed in 4 fetuses.Conclusions PLSVC is always associated with congenital heart defects.The prognosis Of affected fetuses largely depends on whether or not the PLSVC is associated with a congenital heart defect.Prenatal diagnosis of PLSVC can help US plan perinatal counseling and ameliorate the postnatal course.

Objective: To evaluate the diagnostic performance of conventional ultrasound, compression elastography (CE) and acoustic radiation force impulse imaging (ARFI) in diff erential diagnosis of benign and malignant breast tumors. Methods: A total of 98 patients with liver lesions were included in the study. The images of conventional ultrasound, CE and the values of virtual touch tissue quantiifcation (VTQ) of breast lesions were obtained. hTe diagnostic performance of conventional ultrasound, CE and ARFI were assessed by using pathology as the gold standard, and then evaluate the diagnosis effciency of these three approaches in differential diagnosing benign and malignant breast tumors. Results: The specificity, sensitivity and accuracy in the diagnosis of malignant breast tumors for conventional ultrasound were 80.0%, 81.1% and 81.7%, respectively, whereas for CE elastic score were 85.7%, 86.7% and 86.3%, respectively. With a cutoff value of 3.71 for the SR, the sensitivity, speciifcity, accuracy in diagnosis of malignant breast tumors were 97.1%, 83.3% and 88.4%, respectively. With a cutoff value of 3.78 m/s for VTQ, the sensitivity, speciifcity, accuracy in diagnosis of malignant breast tumors were 94.3%, 91.7% and 92.6%, respectively. The difference in diagnosis efficiency among ARFI, CE and conventional ultrasound in differential diagnosis of benign and malignant breast tumors was signiifcant (P<0.05). Conclusion: Conventional ultrasound, CE and ARFI are all useful for the differential diagnosis of benign and malignant breast tumors. But the diagnosis effciency of ARFI is superior to CE and conventional ultrasound. The three approaches can help each other in differential diagnosis of benign and malignant breast tumors.

OBJECTIVETo study the different and the variety of four organic acids in leaves of Isatis indigotica among different cultivated populations in water stress condition and healthy plant.

METHODFour kinds of organic acids, such as oxalic acid, malic acid, ascorbic acid and citric acid from the leaves, were detected by HPLC.

RESULTSignificant differences of four organic acids in the leaves of Beijing, Mongolia, Hebei and Shanxi cultivated populations. Compared with the healthy plant, the content of oxalic acid, malic acid and citric acid in water stress were increased, while the content of ascorbic acid was decreased.

CONCLUSIONContents of four organic acids can act as the guideline factor in I. indigotica because they were related with the water stress condition.

Objective To explore the correlation between acute myocardial infarction(AMI)and neutrophil extracellular traps-os-is(NETosis)in the regulation of cardiomyocyte autophagy in mice.Methods The mouse model of AMI was established in C57BL/6mice by ligation of the left anterior descending coronary artery.Mouse primary cardiomyocytes were treated with oxygen glucose deprivation(OGD)to build an in vitro model of cardiomyocyte injury.Neutrophils were treated with PMA(NETosis inducer)/DNas Ⅰ(NETosis in-hibitor),the supernatant was taken to treat OGD-induced cardiomyocytes,and rapamycin(Rap)was used to treat OGD-induced car-diomyocytes.The myocardial infarction area was detected by TTC staining;serum cTnI level was detected by enzyme-linked immunoad-sordent assay(ELISA);cardiomyocytes apoptosis was detected by TUNEL staining;NETosis marker levels in neutrophil supernatant were detected by ELISA,and related protein expression levels were detected by Western blot.Results TTC staining showed that compared with the sham-operated group,the myocardial infarction area of the mice in the model group was significantly increased,the level of cTnI in serum was significantly increased(P<0.05),the apoptosis of cardiomyocytes was increased,and the levels of Beclin-1 and LC3-Ⅱ/LC3-Ⅰ were significantly increased,the p62 protein expression level was significantly decreased.Compared with the control group,the expression levels of apoptosis and cleaved caspase-3 were significantly increased under OGD conditions(P<0.05).Compared with the control group,the levels of NETosis markers MPO-DNA,MPO,and NE in the neutrophil supernatant in the PMA group were signifi-cantly increased;compared with the PMA-treated group the apoptosis level of cardiomyocytes in the PMA + DNas Ⅰ group was signifi-cantly decreased;the levels of Beclin-1 and LC3-Ⅱ/LC3-Ⅰwere significantly decreased,and the protein expression level of p62 was significantly increased;compared with the PMA + DNas Ⅰ group,Rap treatment could enhance the levels of Beclin-1 and LC3-Ⅱ/LC3-Ⅰ,and inhibit the level of p62(P<0.05).It also significantly reversed the decrease in apoptosis induced by PMA + DNas Ⅰ.Conclusion Neutrophil NETosis can promote AMI in mice by regulating cardiomyocyte autophagy,which can provide a new direction and theoretical basis for the research and development of therapeutic drugs for AMI.

Background/Aims: Inflammatory bowel disease (IBD) may contribute to the development of hematologic malignancies. In this study, the potential relationship between IBD and hematologic malignancies was investigated. Methods: We searched the PubMed, Web of Science, Embase, and Cochrane Library databases for all cohort studies comparing the incidence of hematologic malignancies in non-IBD populations with that in IBD patients, and we extracted relevant data from January 2000 to June 2023 for meta-analysis. Results: Twenty cohort studies involving 756,377 participants were included in this study. The results showed that compared with the non-IBD cohort, the incidence of hematologic malignancies in the IBD cohort was higher (standardized incidence ratio [SIR]=3.05, p<0.001). According to the specific types of IBD, compared with the non-IBD patients, the incidences of hematologic malignancies in ulcerative colitis patients (SIR=2.29, p=0.05) and Crohn's disease patients (SIR=3.56, p=0.005) were all higher. In the subgroup analysis of hematologic malignancy types, compared with the control group, the incidences of non-Hodgkin's lymphoma (SIR=1.70, p=0.01), Hodgkin's lymphoma (SIR=3.47, p=0.002), and leukemia (SIR=3.69, p<0.001) were all higher in the IBD cohort. Conclusions The incidence of hematologic malignancies, including non-Hodgkin's lymphoma, Hodgkin's lymphoma, and leukemia is higher in patients with IBD (ulcerative colitis or Crohn's disease) than in non-IBD patients.
