BACKGROUND:Intervertebral disc can bear load but lack vessels. Nucleus pulposus cel s have the problem of phenotype loss during in vitro culture that can lead to degenerative changes. The mechanism of intervertebral disc degeneration remains unclear.
OBJECTIVE:To explore the approaches of isolation, adherence culture, amplification and identification of the rabbit nucleus pulposus cel s in vitro, to observe the growth characteristics of nucleus pulposus cel s in different generations.
METHODS:Type Ⅱ col agenase digestion method plus explants culture method was used to isolate and purify nucleus pulposus cel s and then amplify in vitro. The morphology and growth of primary and passaged cel s was observed under the inverted microscope, the number of cel s was counted and the growth curve was draw. The morphology of the cel s was observed under light microscope after hematoxylin-eosin staining, and the expressions of col agen type Ⅱ and aggrecan were examined by immunocytochemistry.
RESULTS AND CONCLUSION:Nucleus pulposus cel s of rabbit were isolated, cultured and amplified in vitro successful y. Growth activity was observed, and found that the 1-3 generation nucleus pulposus cel s proliferated more rapidly and vigorously. The proliferation of nucleus pulposus cel s was decreased while the cel passaged more generations. These isolated and cultured nucleus pulposus cel s could positively express the col agen type Ⅱ and aggrecan. In vitro combination of type Ⅱ col agenase digestion method and explants culture method could obtain high purity nucleus pulposus cel s, and the cultured nucleus pulposus cel s were grew in round or polygonal. The 1-3 generation of cel s had strong activity.

Objective To explore the influencing factor of duration of untreated psychosis(DUP) and the relationship between duration of untreated psychosis and treatment outcome in epidemiological first-episode schizophrenia. Methods 912 medical records of the first episode schizophrenia patients were recruited in the study for epidemiological survey . The general medical data, clinical diagnosis, and treatment outcome were collected. DUP was determined refer to symptom onset for schizophrenia (SOS) scale. Patients were divided into short DUP and long DUP groups according to the median values of DUP values. Results Between short DUP and long DUP groups, the difference in marriage was significant ( P < 0. 05). The unmarried patients in the short DUP group (63.7% ) was higher than the long DUP group (52.6% ), the variance was significant (λ2 =5.990, P<0.05). The divorce in the short DUP group (0.6% ) was lower than the long DUP group (4.4% ) , the variance was significant (λ2 =5.079, P<0.01).The simple schizophrenia in the short DUP group (1.5%) was lower than the long DUP group (4. 1% ) , the variance was significant (λ2 =5.868, P<0.05). The treatment outcomes between the two groups had a significant variance ( λ2 =36.093, P < 0.01) , and the Ridit analysis of treatment outcomes between the two groups showed significant difference ( u = 5.183, P<0.01). The marriage,age of onset and clinical diagnosis were significantly correlated with DUP in multiple factor Logistic regression analysis. Conclusion The marriage,age of onset and clinical diagnosis are significantly correlated with DUP in the first episode schizophrenia patients,the longer of DUP and the worse of treatment outcome.

Objective To describe the CT and MR imaging features of hepatic inflammatory myofibroblastic tumor(IMT).Methods The CT(n=12)and MRI(n=2)findings of pathologically proved hepatic IMT in 12 patients were retrospectively analyzed.Results All the tumors of the 12 patients were solitary and located in right hepatic lobe.Six tumors were solid and 4 tumors were solid-cystic.The other 2 tumors were periportal soft-tissue infiltration.The tumors appeared as solid or solid-cystic hypodense mass on CT images.The lesions were dark in T1-weighted sequences and slightly bright on T2-weighted sequences.There was homogeneous or inhomogeneous moderate to significant enhancement in solid portion of the tumors.Honeycomb-like enhancement was demontrated both in the peripheral part and at the intratumoral septa of the solid-cystic mass.Conclusion CT and MRI can provide helpful information for the clinical diagnosis and differential diagnosis of hepatic IMT.

Objective To investigate the microRNAs(miRNAs)expression profiles in the bowels of patients with Hirschsprung disease(HSCR),and to explore the role of differentially expressed miRNAs in the pathogenesis of HSCR. Methods Twenty - seven HSCR tissues,including spastic segments and distending segments,were obtained from patients with HSCR during operation. Then miRNA microarrays were used to investigate the miRNA expression profiles in 6 HSCR specimens. Bioinformatics software was used to predict target genes of miRNA. Three miRNAs (miR - 145 - 3p,miR - 4505 and miR - 1260a)were chosen and quantificational real - time(qRT)- PCR was per-formed to verify the different expression of those three miRNAs in 27 HSCR tissues. Results The expression of 26 miRNAs in an aganglionic colon segment was found to be more than two fold greater than that in ganglionic segment tis-sues,including 19 up - regulated miRNAs and 7 down - regulated miRNAs in patients with HSCR(all P ﹤ 0. 05). Tar-get genes of miRNAs were found,such as SOX10,RET,L1CAM. qRT - PCR showed the expression of miR - 145 - 3p (1. 42 ± 0. 42,aganglionic segment vs 0. 90 ± 0. 31,ganglionic segment)and miR - 4505(1. 30 ± 0. 30,aganglionic segment vs 0. 76 ± 0. 22,ganglionic segment)displayed a statistical difference between groups(all P ﹤ 0. 001). Be-sides,the expressions of miR - 145 - 3p(1. 53 ± 0. 46,long - segment type vs 1. 16 ± 0. 12,short - segment type)and miR - 4505(1. 42 ± 0. 26,long - segment type vs 1. 00 ± 0. 16,short - segment type)showed a statistical difference be-tween different types(all P ﹤ 0. 001),but miR - 1260a(1. 11 ± 0. 25,aganglionic segment vs 0. 99 ± 0. 21,ganglionic segment)did not show differential expression between different groups(P = 0. 064). Conclusions Abnormal expression of miRNAs was found in HSCR spastic segments,suggesting that miRNAs may be involved in the pathogenesis of HSCR.
