ObjectiveTo detect the difference of cytokines and antibodies productions by immunologic system from mice and rabbits vaccinated with the M.RCAg-1 chimeric protein,expressed in E.coli,formulation with different adjuvants,including Freund's adjuvant and three clinically acceptable adjuvants,namely,Al(OH)3,Montanide ISA720 and Montanide ISA51.MethodsSix weeks female BALB/c mice were vaccinated with recombinant protein formulated with different adjuvants through intranasal.Serum were collected to detect specific antibodies of M.RCAg-1 and individual Epitope by ELISA ; natural parasite antigen was recognized by indirect immunofluorescence assay; mouse specific T lymphocyte activation was detected by enzyme-linked immunosorbent spot test (ELISPOT) ; Affinity assay between protein and immune IgG of rabbits with the biosensor,and the growth of Plasmodiumfalciparum in vitro to evaluate by growth inhibition assay(GIA).ResultsDifferent formulation can induce different levels of antibody titers,the effection of ISA51 adjuvant was most closely with Freund's adjuvant,and can induce a higher specific antibody of 11 epitopes within proteins,can effectively stimulate cellular immune response based on the IFN-γ,to avidity Montanide ISA51 adjuvant immune antibodies and M.RCAg-1 protein affinity than the other two adjuvants;and Montanide ISA720 adjuvants and Al (OH)3 adjuvant group in mice can't induce a significant IFN-γresponse(P＞0.05).On avidity assay,the Montanide ISA51 formulation group was better than the other two adjuvants; and Montanide ISA720 and Al (OH)3 adjuvant formulation group can't induce a significant IFN-γresponse in mice(P＞0.05) ; the inhibition rates were 60% and 100% in 3D7 and Dd2 Plasmodium falciparum at a concentration of 2 mg/ml IgG by Montanide ISA51 formulated protein,and IgG of Al( OH)3 formulation could not effectively inhibit the in vitro growth of Plasmodium falciparum( 10% ),while IgG of Montanide ISA720 formulation could not inhibit growth of parasite in vitro.ConclusionBy comparing three clinically acceptable adjuvants and Freund's adjuvant in BALB/c mice and New Zealand rabbit,Montanide ISA51 adjuvants can be acceptable formulated M.RCAg-1 protein induced humoral and cellular immune responses,can be used as one of the candidate adjuvants.

BACKGROUND:Transoral ventral release and posterior fusion have predominated in the treatment of irreducible atlantoaxial dislocation, but there is no consistent conclusion on the clinical efficacy.
OBJECTIVE:To explore the clinical outcomes of transoral ventral release and posterior fusion and screw/rod implantation in the treatment of irreducible atlantoaxial dislocation.
METHODS:A total of 32 patients with irreducible atlantoaxial dislocation undergoing thetransoral ventral release and posterior fusion were selected. After treatment, they received cervical anteroposterior and lateral digital DR and cervical MRI examinations to understand the conditions of nerve compression and bone fusion. The recovery of nerve function was evaluated using Japanese Orthopaedic Association before treatment, 6 months after treatment and during final fol ow-up.
RESULTS AND CONCLUSION:Post-treatment, 29 patients were fol owed-up for an average period of 12 months. (1) Al the patients obtained perfect atlantoaxial joint reduction and bone fusion. This achieved reduction and reconstruction of spinal column stability. (2) Spinal compression was obviously lessened after treatment in al patients, and nerve functions were improved to different degrees. Significant differences in Japanese Orthopaedic Association score were detected between 6 months post-treatment, final fol ow-up and pre-treatment (P<0.05). (3) There were no serious intraoperative complications such as spinal cord or vertebral artery injuries. Postoperative complications such as infection or burst were also not found. (4) Imaging evaluation revealed that transoral ventral release and posterior fusion is safe and effective for treatment of irreducible atlantoaxial dislocation.

Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) could induce extensive and rapid future liver remnant hypertrophy. However, the morbidity for ALPPS is very high. This paper reports a modified ALPPS (associating microwave ablation and portal vein ligation for staged hepatectomy, AMAPS), which was successfully applied in the treatment of huge hepatocellular carcinoma with cirrhosis, and the procedure of operation was greatly simplified. Hence, AMAPS is feasible and safe in selected patients with primary hepatocellular carcinoma and cirrhosis.

Objective: To compare the difference of infrared radiation temperature on body surface of points between healthy people and patients with hyperplasia of mammary glands. Method: The thermaCATMT P30 infrared thermal imaging system was selected to measure the infrared radiation temperature on body surface of eight points in four meridians in 74 patients with hyperplasia of mammary glands and 63 healthy people. Results: The infrared radiation temperatures on body surface of right Youmen (KI 21) in cases with hyperplasia of mammary glands were significantly higher than the healthy people (P=0.009), and the infrared radiation temperatures on left Youmen (KI 21) and other points had no significant difference with healthy people (P>0.05). Conclusion: The infrared radiation temperatures on body surface of right Youmen (KI 21) have significant differences with healthy people. This might occur because of the pathogenesis of hyperplasia of mammary glands and of the specificity of the point Youmen (KI 21).

H2S has a role of protecting neurons from ischemia-reperfusion injury and significantly reducing the cerebral infarction area, but high concentration of H2S can induce neurotoxicity. Memantine, a N-methyl-D-aspartic acid(NMDA)receptor antagonist, could reduce the neurotoxicity of H2S at high concentration. Nine novel structures(compounds I1-I9)were designed by coupling(4-hydroxy phenyl)-3H-1, 2-dithiole-3-thione(ADT-OH)with memantine through alkanes as linkers and synthesized by four-step reactions from ADT-OH. Their neuroprotection against damage induced by glutamate on HT-22 cells was evaluated by MTT method. The results indicated that these compounds markedly increased the survival rates of damaged HT-22 cells at the concentration of 1 μmol/L(P< 0. 01), which suggested that these compounds could preferably protect neurons against damage induced by glutamate.

Retinoid resistance has limited clinical activity of retinoids as differentiation-inducing and apoptosis-inducing drugs. The present study was designed to investigate whether celecoxib (selective COX-2 inhibitor) has effects on cellular retinoid sensitivity of human colon cancer cell lines and its possible mechanism. Cell viability was measured by MTT assay. Apoptosis was detected by Annexin-V/PI staining and flow cytometry assay. PGE2 production was measured by ELISA assay. Expression of RARbeta was assayed by Western blotting. The results showed that celecoxib enhanced the inhibitory effect of ATRA in both COX-2 high-expressing HT-29 and COX-2 low-expressing SW480 cell lines. Further study showed the ATRA and celecoxib combination induced greater apoptosis, and the addition of PGE2 did not affect the number of apoptotic cells induced by the combination. Moreover, NS398 (another selective COX-2 inhibitor) did not affect the inhibitory effects of ATRA on both cell lines. Western blotting showed that the expression of RARbeta in HT-29 cell lines increased in celecoxib group and combination group. And the addition of PGE2 did not affect the expression of RARbeta induced by celecoxib either. In conclusion, celecoxib increased expression of RARbeta and cellular ATRA sensitivity through COX-2-independent mechanisms, which may provide a potential strategy for combination therapy.

BACKGROUNDSurgical treatments for chronic suppurative and cholesteatoma otitis media have been discussed for several decades, but recurrences still occur because of the complex dissection required and hidden lesions associated with otomastoiditis. This study investigated the technology and strategy behind the use of otoendoscopic-assisted otosurgery.

METHODSWe reported on hidden lesions in 32 ears of patients with otomastoiditis between November 2006 and January 2009. All the patients were treated with the aid of an otoendoscope. The advantages of otoendoscopy, including multi-angle light scattering, aperture illumination, and magnification of the local operative field, were utilized in otologic microsurgery, and otoendoscopic operative techniques were introduced for operative sites such as the epitympanum, aditus of the antrum, facial recess, sinus tympani and the mastoid tip.

RESULTSAll patients were followed up from 3 months to 2 years after surgery. All patients recovered well within 3 months following surgery, except for one case of epithelialization of the mastoid cavity occurring 6 months after surgery for cholesteatoma on the cerebellar surface and another case with Bezold's abscess, hyperplastic granulation tissue developed at the antrum.

CONCLUSIONSOtoendoscopy can overcome the technical deficiency of rectilinearity of the visual axis associated with otomicroscopic illumination, which presents a problem when dealing with otomastoiditis lesions in hidden areas. This technique allows such lesions within the complex three-dimensional structure to be visualized and cleaned. Otoendoscopy thus has significant potential for improving the quality of surgery and reducing the risk of postoperative recurrence.
