Objective:To introduce a 2-stage treatment protocol for the management of temporomandibular joint ankylosis with sec-ondary deformities in adults.Methods:24 adult patients (9 males and 15 female)(30 joints)at the average age of 26.1 years un-derwent TMJ reconstruction as the initial surgery,followed by orthodontic treatment and correction of secondary deformities as the sec-ond surgery.Clinical outcome was assessed based on maximal incisal opening,radiography and medical photography.Results:Skele-tal deformities were significantly improved in all patients,satisfactory occlusion was achieved with the orthodontic treatment,average maximal incisal opening increased from 3.4 mm to 32.5 mm(P <0.05).Conclusion:The 2-stage treatment protocol is an effective approach for management of TMJ ankylosis with secondary deformities in adult patients.

This study was to describe the use of inverted-L osteotomy of ramus and iliac bone graft for the management of mandibular deficiency in adult patients. From 2008 to 2010, 11 patients (aged 19 to 29 years) with mandibular deficiency underwent intraoral or extraoral inverted-L osteotomy of ramus and iliac crest bone grafting. Data were collected from the patients' records, photographs and radiographs. The height and width of the ramus were successfully expanded by inverted-L osteotomy and iliac crest bone grafting with minimal complications in all patients, resulting in significant improvement in occlusion and facial appearance. Our early results showed that the inverted-L osteotomy of ramus and iliac crest bone grafting is safe and effective, and should be considered as a good alternative for the patients with mandibular deficiency.

Neuroglobin (Ngb) is a respiratory protein that is preferentially expressed in brain of mouse and man. In this article, Tibetan antelope, living at altitude of 3 000-5 000 m for millions of years, was selected as the model of hypoxia-tolerant adaptation species. Using reverse transcription polymerase chain reaction (RT-PCR) and Western blot techniques, expression of Ngb gene was amplified and analyzed in antelope brain tissue. Our results showed that Ngb homology protein in Tibetan antelope was identified with more sequence similarity with cattle (96%), sheep (95%), and human (95%). We detected that there were some mutations occurred in the Open Reading Frame of Ngb in Tibetan antelope compared with sheep. Phylogenetic analysis of Ngb chain showed that it was closer to cattle than the others. This study suggests possible roles of central nervous system enriched Ngb in adaptation of Tibetan antelope to extremely high altitude.

Energy metabolism plays an important role in life survival for species living in high altitude hypoxia condition. Air-breathing organisms require oxygen to create energy. Tibetans are the well-adapted highlanders in Qinghai-Tibetan Plateau. It was thought that different metabolic approaches could lead to different adaptation traits to high altitude hypoxia. Recently identified hypoxia inducible factors pathway regulators, endothelial PAS domain protein1 (EPAS1)/HIF-2a and PPARA, were involved in decreasing hemoglobin concentrations in Tibetans. Because EPAS1 and PPARA also modulated the energy metabolism during hypoxia, we hypothesized that positive selected EPAS1 and PPARA genes were also involved in unique energy metabolisms in Tibetans. In this brief review, we take a look into genetic determinations to energy metabolisms for hypoxia adaptations traits in Tibetans and mal-adaptive conditions such as high altitude diseases.

OBJECTIVETo investigate the effects of saponins from Anemarrhena asphodeloides Bunge (SAaB) (Botanical Name: Anemarrhena Asphodeloidis Rhizoma) on the growth of vascular smooth muscle cells (VSMCs).

METHODSCell proliferation was measured by a newly developed cell proliferation reagent, WST-1. Cell apoptosis was assayed by flow cytometry through detecting annexin V. Nitric oxide production was evaluated using confocal laser scanning microscopy with diaminofluorescein diacetate (DAF-2, DA). Cell aldose reductase (AR) activity, as well as the effect of Epalrestat and interleukin-1beta were also explored.

RESULTSWST assay showed that cell proliferation induced by serum was significantly inhibited by SAaB (P<0.01). Flow cytometry analysis revealed that SAaB could enhance apoptotic rate of VSMCs (P<0.01). Nitric oxide production was significantly enhanced after administration of SAaB and interleukin-1beta. Moreover, AR activity of VSMCs was also remarkably inhibited by both SAaB and Epalrestat (P<0.01).

CONCLUSIONSAaB can inhibit proliferation and enhance apoptosis of VSMCs. It may protect vascular cells by inhibiting VSMC proliferation and augmenting apoptotic rate of VSMCs via NO-dependent pathway.

OBJECTIVETo explore the correlation between pathological characteristics of target organs and excess evil syndrome in IgA nephropathy.

METHODSData were collected in multicenter cooperation. Totally 266 IgA nephropathy patients were typed into exogenous wind-heat affection syndrome (49 cases), lower energizer damp-heat syndrome (100 cases), damp-phlegm syndrome (43 cases), and blood stasis syndrome (74 cases). Meanwhile, percutaneous renal biopsy was performed in all patients for Hass classification, Oxford classification, Katafuchi integral, and Jiang's classification methods. The correlation between excess evil syndrome and pathological index was analyzed.

RESULTSFour syndrome types were correlated with their Hass levels (r = 0. 341, P <0. 01). Affection of exogenous wind-heat syndrome was correlated with segmental proliferation of endothelial cells and damaged active lesions of segmental capillary loops. Lower-energizer damp-heat syndrome was associated with Hass III level, destroying active lesions of capillary loops, segmental proliferation of endothelial cells, glomerular segmental lesions, focal interstitial infiltration of inflammatory cells, focal interstitial fibrosis and tubular atrophy. Blood stasis syndrome was associated with Hass IV level, glomerular sclerosis, segmental glomerulosclerosis (S)/adhesion, mesangial hypercellularity (M), angiohyalinosis, multi-foci interstitial infiltration of inflammatory cells, multi-foci interstitial fibrosis and tubular atrophy. Phlegm-damp syndrome had higher proportions of Hass I and III levels, but with no association with other pathological parameters.

CONCLUSIONSExcess evil syndrome was associated with partial pathological characteristics of IgA nephropathy. It could reflect pathological damage degree of target organs, activities, chronic lesions, and prognosis of IgA nephropathy to certain extent. Correlated pathological characteristics and its evolution could indicate excess evil syndrome types and their evolution rules.
