OBJECTIVE CYP2 family including CYP2C and CYP2J is the predominant arachidonic acid (AA) epoxygenase, and the epoxidation of AA produces four regioisomeric cis-epoxyeicosatrienoic acids (5,6-, 8,9-, 11,12-, and 14,15-EET). Human CYP2J2 is one of the main CYP isoforms expressed in brain, but CYP2C8 was present at a low level. The aim of this study is to investigate the roles of brain CYP2J in Parkinson disease. METHODS Rats received the right-unilaterally injection with concentrated LV-CYP2J3 or LV-EGFP in the substantia nigra (SN) at 3 d before LPS or 6-OHDA treatment. The animals were tested for rotational behavior with the dopaminergic agonist apomorphine dissolved in sterile saline at 14 and 21 d after LPS injection. The influence of CYP2J-dependent derivative, 14,15-EET, on the genes related with oxidative stress was assayed in SH-SY5Y cells. RESULTS CYP2J overexpression or 14,15-EET treatment significantly increased the levels of SOD1, CAT, GPX1, NRF2 and KEAP1 in neurons. TLR4- MyD88 signaling pathway was involved the down- regulation of CYP2J by LPS. The binding of p-CREB with the promoter of CYP2J was inhibited by the LPS treatment. The loss of dopami?nergic neurons in the right SN induced by LPS or 6- OHDA was significantly decreased by CYP2J3 transfection at 21 d after LPS injection. Compared with LPS or 6-OHDA group, the number of the rotation of rats was decreased by 42.6% and 60.7% by CYP2J3 transfection at 14 d after LPS or 6-OHDA injection;meanwhile, the rotation number was decreased by 12.7% and 21.3% at 21 d. The accumulation of alpha synuclein induced by LPS was significantly decreased by CYP2J3 transfection. The mRNA levels of SOD1, CAT, GPX1, NRF2 and KEAP1 in SN were decreased by LPS, which was attenuated by the injection of LV-CYP2J3. CONCLUSION Brain CYP2J can play a protective role in the damage of the inflammation and oxidative stress to the dopaminergic neurons. Brain CYP2J- dependent derivatives from AA may have therapeutic effects in Parkinson disease via the up- regulation of the antioxidant system in neurons.

Objective To identify the hairless gene mutations in a family of atrichia with papular lesions. Methods Skin biopsies were taken from typical lesions for histopathological examination. Genomic DNA was extracted from blood samples of the family members. Complete encoding sequences of hairless gene Dwere detected by polymerase chain reaction (PCR) and DNA sequencing. Results Compound heterozygous mutations were identified in the patient: G337D in exon 3 and Q498X in exon 4. There was only one of the mutations in his parents and a younger brother. Conclusions G337D and Q498X mutations in hairless gene seem to be responsible for the phenotypes in the patient suffered from atrichia with papular lesions.

Objective To evaluate the analgesic effect of curcumin on trigeminal neuralgia in rats. Methods Thirty healthy adult male Sprague?Dawley rats, weighing 200-250 g, aged 7-8 weeks, were divided into 3 groups ( n=10 each) using a random number table: sham operation group ( group S) , tri?geminal neuralgia group (group TN) and trigeminal neuralgia + curcumin group (group Cur). Trigeminal neuralgia model was established by injecting cobra venom solution into the sheath of the infraorbital nerve ( ION) . Starting from 15 days after establishment of the model, curcumin 45 mg∕kg was intragastrically ad?ministered twice a day for 28 consecutive days in group Cur, while the equal volume of peanut oil was ad?ministered in group TN. Before establishment of the model (baseline), and on 4, 7, 14, 21, 28, 35 and 42 days after establishment of the model, the mechanical pain threshold was measured, the free behav?iors were observed, and the time and frequency of face?grooming and exploratory behaviors were recorded. After observation of the free behaviors, the ION and medulla oblongata on the affected side were removed for examination of the ultrastructure using transmission electron microscopy. Results Compared with group S, the mechanical pain threshold was significantly decreased, the time of face?grooming behaviors was signifi?cantly prolonged, the frequency of face?grooming behaviors was significantly increased, the time of explora?tory behaviors was significantly shortened, and the frequency of exploratory behaviors was significantly de?creased on 4-42 days after establishment of the model in group TN (P<0.05 or 0.01). Compared with group TN, the mechanical pain threshold was significantly increased, and the time of face?grooming behav?iors was significantly shortened on 28-42 days after establishment of the model, and the frequency of face?grooming behaviors was significantly decreased, the time of exploratory behaviors was significantly pro?longed, and the frequency of exploratory behaviors was significantly increased on 21-42 days after estab?lishment of the model in group Cur ( P<0.05 or 0.01) . Microscopic examination revealed that the changes in demyelination of the ION and medulla oblongata were significantly attenuated in group Cur as compared with group TN. Conclusion Intragastrically administered curcumin 45 mg∕kg ( twice a day for 28 consecutive days) can attenuate trigeminal neuralgia in rats, and the mechanism is related to the attenuated changes in demyelination of the ION and medulla oblongata.
