Objective To predict and identify T cell epitopes of major group 3 allergen derived from Dermatophagoides fari-na(Der f 3). Methods The T cell epitopes of Der f 3 were analyzed through the sequence analysis by using the bioinformatics online tools. The five predicted peptides of T-cell epitopes were artificially synthesized. The spleen lymphocytes were co-cultured with the five T cell epitopes by using the modified MTT method and the levels of IL-2,IFN-γ,IL-4 and IL-5 in the supernatant of the cultures were detected by ELISA. Results Five T cell epitopes of Der f 3 were predicted and three of which could pro-mote the proliferation of the mouse spleen lymphocytes. The secretions of IL-2 and IFN-γwere significantly induced and the se-cretions of IL-4 and IL-5 were significantly decreased by three of five prediction epitopes of Der f 3:37GDCPYQISLQSSSHFC-GG54,98IYQHENYDSMTIDNDVALIKLKTPMT123 and 164SELQRVDIDVVSREQCDQLYS184. Conclusion Three T cell epitopes of Der f 3 have been initially identified,which lays the foundation of the diagnosis and treatment of asthma.

Objective To investigate the change of apoptosis in LNCaP cells after inhibition of autophagic process under androgen removal conditions. Methods The autophagic level was deter-mined by using confocal microscopy and RT-PCR. The DAPI staining was used to indicate the apopto-sis of LNCaP cells after inhibition of autophagic by 3-MA. Also, Z-VAD-FMK was used to extend the apoptosis results. Results ①Androgen deprivation led to increased autophagy in LNCaP cells. LN-CaP cells cultured in complete medium(CM) presented low autophagic process with 1.9 scores. After 24 hours, the punetate GFP-LC3 structures were accumulated in the cells cultured in serum-free medi-um (SF)(2.64 scores). In contrast, the number of punctate GFP-LC3 remained at a very low level (1.85 scores), when cells were incubated with DHT in SFA(serum-free medium+DHT). Statistical analysis showed the significant difference between SF and SFA (P<0.01). Semiquantitative RT-PCR was employed to examine the mRNA expression of LC3. Indeed, cells grown in the medium without serum had a higher LC3 mRNA expression with the highest at 12 hour time point as compared with the cells grown in CM. DHT treatment reduced the level of LC3 mRNA. ②Blockage of autophagy by 3-MA increased the apoptosis of LNCaP cells. LNCaP cells in SF and SFA just presented a basal level of apoptosis, which is (3.19±1.09)% and (3.01±0.33)% , respectively. Under androgen-free con-ditions, inhibition of autophagy by 3-MA could increase apoptosis significantly(10. 90±2.91%). While Z-VAD-FMK, a pan Caspase inhibitor, was able to suppress this apoptotic process to the level of (1.16±0.52)%, which was statistically significant(P<0.01). Conclusions Androgen removal can lead to the increase of autophagy in LNCaP cells. Moreover, inhibition of autophagy promotes the occurrence of apoptosis.

Objective:To investigate the complications of traumatic optic neuropathy and to call the surgeons' attention to precaution. Method:Retrospectively analysis of 122 cases patients with traumatic optic neuropathy and 3 cases were analyzed in detail including 1 case with purulent meningitis, another 1 case with internal carotid artery pseudoaneurysm and the other 1 case with internal carotid artery cavernous sinus fistula. Result:Most of the patients had the complications of orbital fracture, maxillofacial fracture, ocular and craniocerebral injury. A few of patients had other injuries all over the body. The case with purulent meningitis was cured with antibiotics. The case with internal carotid artery pseudoaneurysm was cured with neurosurgery. The visual acuity of the both cases were improved. The case with internal carotid artery cavernous sinus fistula died of severe hemorrhea. Conclusion: The patient with traumatic optic neuropathy has the possibility of severe cranial disorders,orbital fracture, maxillofacial fracture and injuries of viscera or limbs. It should be paid mare attention and treated accordingly.
