Objective To compare the changes in the management of severe preeclampsia during a ten-year period, and the maternal and perinatal outcome. Methods Totally, 305 cases of severe preeclampsia were collected in our hospital from January 1999 to December 2003. The management, mode of delivery, frequency of complications and maternal and fetal outcomes were compared with the 349 cases from January 1994 to December 1998. Results The incidence of severe preeclampsia, that being diagnosed at 0. 05], but the perinatal mortality rate of those cases

Objective To explore the role of next-generation sequencing(NGS)technology in the assisted diagnosis of RA-Sopathies.Methods Peripheral blood was extracted from 1 child patient with suspected Noonan syndrome and her parents,and the gene mutations were detected by adopting the aCGH and NGS.The results were verified by Sanger sequencing.Results The NGS results revealed that the heterozygous mutation of c.1406G>A existed in BRAF gene,and the results of Sanger sequencing in this child case was consistent with the NGS results.The Sanger sequencing results in her parents showed the locus was G/G wild type. Conclusion This child case was diagnosed as CFC.NGS plays a good auxiliary role in the differentiation diagnosis of RASopathies.

Objective To evaluate the changes in the expression of neuroligin1 in excitatory postsynaptic membrane of the spinal dorsal horn in a rat model of inc isional pain.Methods Forty-eight pathogen-free healthy adult male Sprague-Dawley rats,aged 6-8 weeks,weighing 280-320 g,were divided into control group (group C,n =12) and incisional pain group (group Ⅰ,n=36) using a random number table.A1 cm long incision was made in the plantar surface of the right hindpaw in group Ⅰ.Cumulative pain score (CPS) was assessed and mechanical paw withdrawal threshold to von Frey stimuli was measured at 3 hand 1 and 3 days after operation (T1,2,3).The animals were then sacrificed and their lumbar segments (L3-6) of the spinal cord were removed for detection of the expression of neuroligin1,postsynaptic density-95 protein (PSD-95),glutamate receptor 1 (GluR1) and GluR2 in the postsynaptic membrane of spinal dorsal horn (by Western blot) and co-expression of neuroligin1 with PSD-95 in spinal dorsal horn (by co-immuno-precipitation).Results Compared with group C,CPS was significantly increased and mechanical paw withdrawal threshold was decreased at T1-3,and the expression of neuroligin1 and GluR1 in the postsynaptic membrane of spinal dorsal horn at T1,2 and co-expression of neuroligin1 with PSD-95 at T1 were up-regulated in group Ⅰ (P<0.01 or 0.05).Conclusion The development and maintenance of incisional pain is related to the signaling pathway regulated by neuroligin1 in excitatory postsynaptic membrane of the spinal dorsal horn of rats.

OBJECTIVE:
To carry out genetic diagnosis for a pedigree affected with cutis laxa.
METHODS:
Genomic DNA was extracted from peripheral blood samples from members of the pedigree and 50 unrelated healthy controls. Potential mutation was screened by next-generation sequencing and verified by Sanger sequencing.
RESULTS:
A heterozygous c.1985delG mutation was identified in the ELN gene among all patients from this pedigree. The same mutation was not found among unaffected family members and 50 healthy controls.
CONCLUSION
The genetic etiology for the pedigree has been elucidated, which has enabled genetic counseling and guidance for reproduction.
