Studies have shown that IL-24 is the only cytokine capable of inhibiting tumor growth and neovascularization as well as stimulating immune system. IL-24 exerts its inhibition effects through pathways independent of p53, Rb, p16 and other tumor suppressor genes and has no effect on normal cells. IL-24 has emerged as a hot topic in cancer therapy research.

A collective intelligent perception-supported and RDAWA-based reader-driven acquisition model of li-brary holdings was proposed with the development of academic library holdings as its background .The design ideas of RDAWA were described , the master framework of RDAWA was analyzed , the considerations in design of RDAWA that simplified the input procedure and met the reading requirements of readers were elaborated with the biblio-graphic information database , data analysis module and acquisition order generation algorithm summarized .

Objective To explore the clinical characteristics of neuromyelitis optica(NMO).Methods The clinical data of 18 patients with NMO were analyzed retrospectively.Results Of the enrolled patients,15 cases(83.3%) were relapsing form of NMO,16 cases(88.9%) were female and the mean onset age was 36 years old.Simultaneous bilateral optic neuritis(ON) or ON occured sequentially and horizontal impairent of spinal cord were the main clinic features in these 18 patients.Of the patients who received spinal cord MRI examinations,4 cases showed the lesions located in cervical cord,6 cases in thoracic cord and 5 cases in both cervical and thoracic cord.13 cases revealed lesions in spinal cord extended across 3 or more vertebral segments.Furthermore,brain lesions were detected by MRI in 6 patients.The mean onset number of per patient was five.Seven patients presented with mild disability,7 patients with median disability,2 patients with severe disability and death of 2 patients.Conclusions Most patients with NMO are female and relapsing form accounts for the majority type.The cardinal manifestations are bilateral ON and longitudinally extensive transverse myelitis(LETM).Some patients show brain lesions that may be detected by MRI examination.Relatively high relapsing frequency of clinical event and severe impairing are common in NMO.

Objective To explore the clinical,imaging and pathologic features of hypertrophic cranial pachymeningitis (HCP).Methods The clinical data of one HCP patient who treated in our hospital and other 77 HCP patients from literatures were analyzed retrospectively.Results The clinical manifestation of all the 78 HCP patients had chronic headache,multiple cranial nerves impairment.The secondary was psychiatric disorder(10.3%),ataxia(9.0%) and seizure disorder(6.4%).Hemiplegia,menorrhea and galactosis were found few.Headache was the first onset symptom in the 74 cases (94.9%).HCP was often misdiagnosed subarachnoid hemorrhage,hypotensive cranial pressure headache and cerebral venous sinus thrombosis in early stage.MRI demonstrated local or diffused thickened dura,especially in cerebral falx and/or tentorium of cerebellum,which could be enhanced through reinforced scanning.Pathological evidence indicated an obvious proliferation of dura fiber tissue accompanied with inflammatory cells infiltration.Corticosteroid was effective to all the cases.Conclusions The clinical manifestation of HCP was multiplicity,but it mainly was chronic headache and multiple cranial nerves impairment.MRI demonstrates local or diffused thickened dura especially in cerebral falx and/or tentorium of cerebellum.MRI has an important significance for diagnosis.

Objective To investigate the expression of endothelin converting enzyme (ECE) mRNA in patients with acute cerebral infarction (ACI) and its clinical significance.Methods Blood samples from 40 patients with ACI (patient group) within 72 hours after the onset of ACI and 28 gender and age-matched healthy subjects (control group) were collected on admission. Plasma concentrations of endothelin-1 (ET-1) as well as the serum levels of cholesterol, triglyceride, low density lipoprotein,high density lipoprotein, apoA1, apoB, lipoprotein a and fasting plasma glucose in each sample were measured and analyzed. Additionally, semi-quantitative RT-PCR was performed to check the ECE mRNA level in the blood cells. European stroke scale (ESS) was used to evaluate ACI patients' neurological deficit on admission.Results (1) ECE mRNA could be detected in every blood sample from either patient group or control group. However, the ECE mRNA level increased significantly in the patient group compared with that in the control group (0.31?0.092 versus 0.25?0.10, t=2.46, P=0.016). (2) The plasma ET-1 concentration in patient group was also significantly higher than that of control subjects (183.27?56.63pg/ml versus 156.47?34.24 pg/ml, t=2.23, P=0.029). (3) Plasma ET-1 concentration was negatively correlated with ECE mRNA level in the control group (r=-0.452, P=0.021). However, the result in the patient group was not the same as the control group. (4) The ET-1 concentration and ECE mRNA level in the patients had histories of hypertension, diabetes mellitus and stroke were not significantly different from those in the patients without these histories. (5) No significant correlation existed between plasma ET-1 concentration and ECE mRNA level and age of the patient, ESS score, fasting plasma glucose and serum lipid. Conclusions ECE mRNA level is significantly increased in the early stage of ACI, which may be associated with the acute-phase reaction of cerebral infarction and may have deleterious effects on the development of neuronal injury. Our results suggest the protective reflection in the endothelin system of normal human body may be disturbed by the onset of ACI. The relationship between ECE mRNA level and neurological deficit degree, stroke risk factors is worthy for further study.

Objective To detect the serum anti‐sialic acid glycoprotein receptor antibody (anti‐ASGPR) levels in the patients with chronic hepatitis B(CHB) ,chronic hepatitis C (CHC)and healthy people ,and to observe the relationship between anti‐ASGPR and the disease development in the patients with hepatitis .Methods Totally 60 patients with hepatitis B virus (HBV) infection(30 cases of CHB and 30 cases of CHB cirrhosis) and 60 patients with hepatitis C virus (HCV) infection(30 cases of CHC and 30 cases of CHC cirrhosis) were selected with 60 persons undergoing the physical examination as the control group .The anti‐ASGPR and ALT levels in all research subjects were detected with ELISA .Results (1)The anti‐ASGPR level in the HBV and HCV infection groups was significantly higher compared with the control group ,and the difference was statistically significant(P<0 .01) .The an‐ti‐ASGPR level in the CHB cirrhosis group was significantly higher than that in the CHB group ,and the difference was statistically significant(P<0 .05) .The anti‐ASGPR level in the CHC cirrhosis group was significantly higher than that in the CHC group ,and the difference was statistically significant(P<0 .05) .No correlation between anti‐ASGPR and ALT was found .(2) The anti‐ASG‐PR level in the CHC group was significantly higher than that in the CHB group ,and the difference was statistically significant(P<0 .01) .Conclusion The detection of anti‐ASGPR is helpful for clinical differential diagnosis and has an important significance for the treatment and prognosis .
