Oncomodulin(OM) is a kind of Ca-bind protein(CABP),and it belongs to the tropon in C super family.It different from other CABP because of its special domain(CD domain) which could bind with Ca2+.Multiple functions of OM have been determined during the study of its construction and distribution.It plays very important role in adjusting cell electric activity,regulating cell signal conduction passageway and cell cycle.In recent years,the study on OM promoting axon regeneration is emerging,especially in the regeneration of optical nerve.It offers a basis for solving the regeneration of spinal cord and cranial nerve.The concept,construction and distribution,action mechanism and its relationship with regeneration of optical nerve were reviewed in this article.

1.0 ?mol/L),the toxicity and side effects of MTX increased significantly.The most common drug side effects were gastrointestinal symptoms and leucopenia.The oral mucosal lesions became worse in 12 g/m2 group.Conclusion The monitoring of HD-MTX plasma concentration provides an objective clinical basis for the individualized chemotherapy.

To generate recombinant adenovirus expression vector of human Sema4C gene and observe its expression in mouse myoblasts cell line C2C12 for ensuring easy access to investigate the role of Sema4C gene during myogenesis. The recombinant plasmid was packaged and amplified after being transfected in HEK293 cells through Lipofectamine. After infecting C2C12 myoblasts with recombinant adenovirus vector, the adenoviral infection efficiency was determined by confocal microscope which showed that the expression of green fluorescence could be detected at 12h and then reached peak at 24h after recombinant adenovirus infection. The infection efficiency was almost 100% confirmed by FACS examination. Detection of WB indicated that the expression of Sema4C in C2C12 of recombinant adenoviral infection group was significantly higher than that of the control group (P

Abstract: Objective　To detect the antibody levels of hantavirus in serum samples from patients suspected with hemorrhagic fever with renal syndrome (HFRS) in Heilongjiang Province from 2019 to 2021, and to provide scientific basis for the prevention and control of disease. Methods　Enzyme-linked immunosorbent assays (ELISA) were used to detect the IgM antibodies to hantavirus in serum samples collected from suspected patients with HFRS in the acute-phase, and IgM and IgG antibody in convalescent-phase serum samples. The positive rate of IgM antibody in acute-phase serum samples of patients in different years was analyzed with χ2 test by SPSS 19.0, and the data were sorted out and analyzed about patients' gender, occupation, age, date of onset and interval from onset to initial diagnosis by EpiData 3.1, Excel 2003 software. Results　A total of 351 acute-phase serum samples and 208 convalescent-phase serum samples were detected in patients suspected with HFRS, respectively. There were 317 positive IgM antibodies of serum samples in the acute stage, with the positive rate of 90.31%. There was no significant difference in the positive rate of IgM antibodies in the acute stage between different years (χ2=0.895, P=0.639). T The IgM antibodies and IgG antibodies were positive in 32 (15.39%) and 28 (13.46%) of the convalescent-phase serum samples, respectively. Moreover, 148 patients (71.15%) were double-positive for IgM and IgG antibodies at the convalescent stage. The ratio of male to female patients was 4.56∶1, for which male patients were much more than female patients. Occupation was dominated by farmers (253 cases, 79.81%), followed by workers (19 cases, 5.99%) and the unemployed (17 cases, 5.36%), respectively. The age of patients ranged from 10 to 88 years old, with a median age of 49 years old. Most of the patients were in the age group from 30 years old to 60 years old (209 cases, 65.93%), among which the age group from 40 years old to 50 years old (86 cases, 27.13%) had the highest proportion, and the age group from 60 years old to 90 years old had a proportion of 20.18% (19 cases). May and November were the peak periods of HFRS in Heilongjiang Province. The median interval between onset and initial diagnosis was 4 days. Conclusions　There is a gap of about 10% between the clinical diagnosis of HFRS cases and the confirmed cases detected by laboratory in Heilongjiang Province from 2019 to 2021. The virus-specific detection results are important for confirming the diagnosis of local patients with HFRS.

Objective To evaluate the effects of 131 adrenoceptor anfisense on blood pressure and?1 adrenoceptor mRNA and protein levels in 2 kidney 1 clip(2K1C)rats.Method 2KIC hypertensive rots were produced by clipping renal artery of SD rats.Liposome/AS-ODNs 2.0 were tested intravenously in rats with 2KIC hypertension.Animals were divided into 5 groups(n=18 in each group):?1-AS-ODN group,?1-IN-ODN group,2K1C group,Sham group and SD group.Blood pressure was measured by tail-cuff method,the levels of myocardial?adreneceptor mRNA and protein were tested by RT-PCR and binding assay.Results On the basis of the magnitude and duration of hypotension,?1-AS-ODN decreased blood pressure by 39 mmHg at the most for 4 weeks.Compared with the 2KIC group,?1-AS-ODN did not significantly change the levels of myocardial?1 adrenoceptor mRNA but significantly decreased the levels of myocardial?1 adrenoceptor protein at 2,7,30 days (P

Objective To explore the relationship between the serum level of E-selectin and S128R polymorphisms in the exon 4 of E-selectin gene and acute myocardial infarction (AMI) in local Han peoples. Method The genotype of E-selectin were detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method in 168 patients with acute myocardial infarction and 200 healthy controls,and the serum level of E-selectin was measured by enzyme-linked immunosorbent assay (ELISA).Results There was significant difference in frequencies of allele and genotype in S128R polymorphism between acute myocardial infarction and control groups respectively,The relative risk suffered from acute myocardial infarction of SS genotype was 2.234 times of the SR genotype (OR=2.234,95% CI:1.112～4.437),The serum E-selectin level was significantly higher among carriers of SR genotype as compared with SS genotype (41.65?8.87)?g/L vs (34.23?6.72)?g/L,P

Objective To explore the clinical characteristics and treatment of Caroli′s disease in children.Methods The clinical data,laboratory examination and radiological feature of 8 children with Caroli′s disease between Feb.1998 and Dec.2007 were analyzed retrospectively.All children underwent CT and abdominal ultrasonogram.Results Five cases of the 8 children were male and 3 cases were female.The mean age was 6.3 years old.The cases′ history were from 5 days to 4 months.The clinical symptoms showed that 3 cases had hematemesis,5 cases had hepatosplenomegaly,and 1 case had fever and turbid urine.Of the total 8 cases,5 cases were hepatic fibrosis and liver cirrhosis and hepatosplenomegaly,3 cases were portal hypertension,and 1 case had cholangitis.The other 3 cases were simple types.One case had infantile polycystic kidney disease.Laboratory analysis revealed 2 cases had dysfunction of liver and 1 dysfunction of renal.The imaging characteristics showed multiplied irregular dilatation of the intrahepatic bile ducts in enlarged liver,with central dot sign on CT scan.One case presented enlarged gastroesophageal vein.The 8 cases undertook conservative treatment,with no surgery.Conclusions The symptoms of Caroli′s disease are highly variable.Caroli′s disease should be focused especially on children with abdominal pain and hepatomegaly.CT is important for diagnosis of Caroli′s disease at earlier stage.The disease can be conservatively treated,and(or) surgically operated.
