ABSTRACT
Objective:To explore the common risk factors of intracerebral hemorrhage(ICH) in young people and to establish a predictive model of nomogram.Methods:The relevant data of young patients with ICH (≤45 years ) hospitalized in the Department of Neurosurgery of Dezhou people's Hospital from January 2014 to August 2021 were retrospectively studied, and the young group who underwent physical examination in the Physical Examination Center of Dezhou people's Hospital at the same time were randomly selected as the control group. Analyze the risk factors that may affect cerebral hemorrhage in young people, screen the risk factors with statistical differences through single factor analysis, screen the independent risk factors according to multi factor Logistic regression analysis, construct the risk nomogram model of cerebral hemorrhage in young people, and test the efficiency, goodness of fit and benefit of the constructed model through internal validation.Results:Compared with the control group, there were statistically significant differences in family history (χ 2=115.66, P<0.001), hypertension grade( Z=17.67, P<0.001), smoking history (χ 2=33.91, P<0.001), drinking grade ( Z=4.84, P<0.001), body mass index (BMI) ( t=11.76, P<0.001), low density lipoprotein ( t=4.78, P<0.001), high density lipoprotein cholesterol ( t=5.83, P<0.001),blood glucose ( Z=5.68, P<0.001) and homocysteine ( Z=2.22, P<0.001) in the case group. Binary Logistic regression analysis showed that hypertension grade ( OR=3.457, 95%CI: 2.809-4.254, P<0.001), family history ( OR=2.871, 95%CI:1.868-4.413, P<0.001), BMI ( OR=1.093, 95%CI:1.040-1.148, P<0.001), high density lipoprotein cholesterol ( OR=0.230, 95%CI:0.111-0.480, P<0.001), blood glucose ( OR=3.457, 95%CI:2.809-4.254, P<0.001), homocysteine (O R=3.457, 95%CI:2.809-4.254, P<0.001) was an independent risk factor for intracerebral hemorrhage in young adults. The nomogram prediction model showed that BMI was 96 points, hypertension grade was 100 points, family history was 30 points, high density lipoprotein cholesterol was 76 points, homocysteine was 48 points, blood glucose was 52 points,homocysteine was 48 points and blood glucose was 52 points, respectively. The consistency coefficient of the prediction model was 0.874. The nomogram dependent ROC curve AUC was 0.891, and the corresponding sensitivity and specificity were 74.5% (263/353) and 89.7% (437/487), respectively, a nomogram model was established with good diagnostic efficiency. Conclusion:The nomogram model established in this study can predict the probability of intracerebral hemorrhage in high-risk population, and take intervention measures as early as possible to prevent the occurrence of intracerebral hemorrhage in young people.
ABSTRACT
The use of high flow nasal cannula(HFNC) therapy as a noninvasive respiratory support approach for preterm infants is rapidly increasing.HFNC is an alternative to nasal continuous positive airway pressure(nCPAP) for treating apnea of prematurity,primary respiratory support for neonates with respiratory distress,post-extubation support,facilitating nCPAP weaning in preterm infants.In this article,the proposed mechanisms of HFNC and the evidence from clinical trials of HFNC use in preterm infants were reviewed,and recommendations for evidence-based practice were established.
ABSTRACT
Objective To explore and summarize the clinical features and treatmentof the nonpuerperal mastitis.Methods Eighty-two cases of nonpuer-peral mastitis from 2003 to 2013 were analyzed retrospectively.All patients were divided into surgery alone group (11 cases)and medication combined surgery group (71 cases),which PDM patients with triple anti-mycobacterial drugs therapy,GM patients with cortical hormone therapy.Results All patients were diagnosed by biopsy.The total duration of simple drug group (triple or hormone) is (11.92 ±6.50) weeks and remission rate after 4 weeks was (89.06 ± 2.25) ％.Drugs plus surgery group,the total duration of the group is (6.57 ± 2.30) weeks,and no recurrence.The total duration of the simple surgery group is (17.09 ± 13.11) weeks and remission rate after 4 weeks was (63.64 ± 1.10) ％.Comparison of the total duration of the three groups and the cumulative response rate curves were significantly different(P ＜ 0.05).Conclusions Nonpuerperal mastitis requires a combination of clinical and pathological diagnosis.Surgery is not the only treatment option,triple anti-mycobacterial or cortisol hormones for different types of pathology conservative treatment can achieve a satisfactory therapeutic effect.Drug therapy combined with surgery can shorten the duration and reduce the relapse rate,it is an effective treatment for nonpuerperal mastitis.
ABSTRACT
Objective To establish the quality control method for Bushenbanlong Tablet. Methods The content of astragaloside was determined by HPLC-ELSD. Results The linearity range was 1.44～4.32 ?g with a correlation coefficient r=0.999 9, and the average recovery was 99.69% with RSD=1.16%. Conclusion The method was simple, convient, quick and sensitive. It provide an effective method for quality control of Bushenbanlong Tablet.
ABSTRACT
<p><b>OBJECTIVE</b>This investigation aimed at explore the total distribution of neuropeptide Y-like immunoreactive (NPY-LI) fibers and their changes post-trauma in rat temporomandibular joints (TMJs).</p><p><b>METHODS</b>Six groups of rats were killed individually before trauma, 1, 3, 7, 14 and 28 days after trauma. TMJs were extracted totally, and the avidin-biotin-peroxidase complex method and image analysis were employed to detect NPY-LI fibers in frozen sections of TMJs.</p><p><b>RESULTS</b>NPY-LI fibers were distributed extensively in TMJs, except the central disc band and bone, and they were mainly located around blood vessels, especially arteries. The densities of fibers in the six groups were 160.4 +/- 27.5, 95.8 +/- 16.4, 88.6 +/- 14.5, 114.3 +/- 17.0, 135.0 +/- 20.7, 158.6 +/- 19.5 (unit:mm2).</p><p><b>CONCLUSION</b>NPY-LI nerve fibers are distributed extensively in the periphery of blood vessels of TMJs and densities changed dynamically when TMJs were impacted. NPY may play an important role in pathologic change of TMJ by regulating local blood circulation.</p>

The nutritive composition from tissues of Perinereisaibuhitensis was analyzed. The result indicated that there was 67. 43% amino acids and 14. 24% fatty acids in the tissues, a-mong them the EPA comprises 6. 5343% of the total fatty acids and the glutamic acid comprises 10. 288% of the whole tissues. In the meanwhile, the tissues also contains high content of trace elements, such as zinc, iodine, selenium as well as fibrinolytic enzymes and so on, showing a prospective application value in the future.
ABSTRACT
Objetive:To investigate the relationship between recurre nt aphthae and immunologic reaction on Helicobacter pylori (H. pylori) i nfection. Methods: The dental plaque was collected and the blood serum were extracted from 107 patients with recurrent aphthae and 99 he althy individuals. H. pylori infection was detected by urease test, and the antibody to H. pylori was detected by ELISA assay. Results: In the dental plaque the detectable rate of H. pylori was 53.3% in t he patients and 32.3% in the controls (P0.05). The quantitative analysis showed that the level of anti-H . pylori antibody (?g/ml) in the controls,the patients with light recurrent a phthae and those with severe was 17.69?4.41,29.30?8.24 and 41.75? 9.73 res pectively (P
ABSTRACT
Active fractions were obtained from the c(?)amworm homogenate by reverse-phase concentration, gel filtration and affinity column chromatography. The MTS/PMS assay was used in the screening of antimicrobial peptide in vitro. The MTS/PMS assay and ELISAAFP method were combined to evaluate the effects of antimicrobial peptide on the proliferation and ?-fetoprotein secretion of HepG2 cells as well as on the proliferation of normal mouse osteoblast MC3T3-E1. The results showed that the purified antimicrobial peptide from clamworm Murphysa sanguinea was a constitutive basic protein with MW 8.1 kDa and pI 8.6, which showed inhibition effects on the proliferation and ?-fetoprotein secretion of HepG2 cells at different levels. These effects have a positive correlation with the concentrations of antimicrobial peptide. No obvious inhibition and damage effects were observed on the normal osteoblast.
