BACKGROUND:Prosthetic appliance is often adopted for clinical maxilary repair, which can maintain swalowing and language function in patients with a certain extent, but if the defect is too large, the prosthesis has a poor fixed effect that is prone to inducing various adverse consequences. OBJECTIVE:To explore the maintenance effect of titanium mesh combined with forearm free flap on swalowing and language function in patients with maxilary defects. METHODS:A total of 35 patients with maxilary defects, 19 males and 16 females, aged 33-93 years, were enroled. Among them, 17 patients underwent maxilectomy and wound packing with iodoform gauzes, and then after 1 year, these patients were given prosthesis repair as control group; another 18 patients were subjected to titanium mesh combined with forearm free flap for repair of maxilary defects as observation group. Al the patients were folowed up for 24 months, and the swalowing and language functions were evaluated. RESULTS AND CONCLUSION:At 24 months after repair, al the patients were satisfied with facial appearance, and there were no adverse reactions related to repair materials. Scores on swalowing function, language function, pain fucntion, face function, motor function, entertainment function, masticatory function and oral health were significantly higher in the observation group than the control group (P < 0.05), and the score on the shoulder dysfunction was lower in the observation than the control group, indicating the patients in the observation group had a higher quality of life than those in the control group. These findings indicate that titanium mesh combine with forearm free flap for maxilary defect repair can be better to maintain the swalowing and language function of patients.

BACKGROUND: Hypoxia-inducible factor 1α may mediate mammalian cells to adapt hypoxia environment.OBJECTIVE: To observe high altitude hypoxia on the ultrastructure of the lung tissue of hypoxia-inducible factor 1α expression.METHODS: Sprague-Dawley rats underwent high altitude hypoxia intervention for 1, 2, 3 and 30 days. Control group was set. Four high altitude hypoxia groups consisted of Golmud, Qinghai at the altitude of 2 700 m from 5-m above sea level of Xi'an consuming 1 day, Tanggula region at 5 000 m above sea level consuming 2 days, and Tibet Nagqu at 4 500 m above sea level consuming 3 and 30 days, respectively.RESULTS AND CONCLUSION: Light and electron microscopy showed that acute high altitude hypoxia 2 day group presented apparent high altitude pulmonary edema, while the 30 day group of acute high altitude hypoxia of high altitude pulmonary edema was significantly reduced, but hypoxia-inducible factor 1α mRNA expression was significantly increased (P < 0.01). Results demonstrate that hypoxia-inducible factor 1α mRNA expression increase in lung tissues after hypoxic acclimatization can help ameliorate high altitude pulmonary edema.

Objective To investigate the cellular localization of the neural precursor cell-expressed, developmentally downregulated isoforms(Nedd4), Nedd4- 1/2 and Nedd4- 2, and the serum glucocorticoid- inducible kinasel(SGK1) in various subregions of the rat cochlea. Methods The expression patterns of Nedd4-1/2, Nedd42 and SGK1 in the cochlea of rat were studied by immunohistochemistry with the specific polyclonal rabbit antibodies against the rat Nedd4-1/2, Nedd4-2 and SGK1. Results All three proteins were extensively expressed in various regions of the rat cochlea. They were found in the stria vascularis, spiral ligament, organ of Corti, spiral limbus, spiral ganglion and Reissner's membrane. Conclusion Our findings suggest that there exists a Na+ transport system in the cochlea consisting of SGK1, Nedd4 isoforms and ENaC, which may work in concert to transport Na+ and to maintain homeostasis in the inner ear as they do in other tight epithelia.

[ABSTRACT]OBJECTIVETo evaluate the efficacy of combined oral and intratympanic glucocorticoids treatment for severe to profound sudden sensorineural hearing loss(SSNHL).METHODSFifty-four patients with severe to profound SSNHL were retrospectively studied. They were treated with oral steroids, vasodilators, anticoagulants. The patients who accepted intratympanic methylprednisolone sodium succinate were included the therapy group, the others were included in the control group. Hearing improvements were analyzed respectively after two weeks.RESULTSHearing in both groups were improved significantly after treatment(P<0.01), but there was no difference in hearing improvements between two groups(P=0.194). The efficacy for severe SSNHL patients in therapy group was equal to those who were in control group (P=0.251), so was the efficacy for profound SSNHL patients in both groups(P=0.380).CONCLUSIONThe combined systemic and intratympanic glucocorticoids treatment was effective for patients with severe to profound SSNHL, but while with no better efficacy than oral glucocorticoid alone.

[Summary] Traditional anterior thoracotomy surgery for thoracic idiopathic scoliosis has amount of disadvantages such as large trauma,postoperative pain,and pulmonary function decrease.Video-assisted thoracoscopic surgery (VATS),which is considered as an effective method for the treatment of idiopathic thoracic scoliosis,can avoid those disadvantages as compared with thoracotomy surgery.Common surgical procedures include anterior spinal release with intervertebral fusion and instrumentation through video-assisted thoracoscopic surgery (IVATS).This article reviewed the history,indications,contraindications,advantages,disadvantages and outcomes of VATS in the treatment of idiopathic thoracic scoliosis.

Objective To observe the clinical effect of DC-CIK cells combined with S-1 in the treatment of non-small-cell lung cancer.Methods 76 patients with non-small-cell lung cancer were randomly divided into the observation group and the control group on average.The control group was treated with S-1,and the observation group was treated with DC-CIK cells combined with S-1.For the observation group,the peripheral venous blood was collected before the treatment for DC cells and CIK cells cultivation.The expression of CD4+/CD8+,CD4+ and NK cells in the peripheral blood of the two groups was detected by flow cytometry before the treatment and after one week of the treatments.Besides,the number of white blood cells and platelet count were also measured and the symptoms of non-small-cell lung cancer were observed.Results The percentage of CD4+/CD8+,CD4+ and NK cells in the peripheral blood of the observation group after the treatment was (1.65±1.03),(34.56±8.90) and (18.68±7.98),respectively,which was significantly higher than (1.32±0.70),(29.07±7.15) and (15.28±8.23) in the control group (all P＜0.05).There was no significant difference in the percentage of CD8+ cells between the observation group (25.56± 8.90) and the control group (26.64±6.77) (P＞0.05).The vomiting,leukopenia and thrombocytopenia in the observation group were less than those in the control group (all P＜0.05).The one-year survival rate was 52.63％ in the observation group which was significant higher than 42.11％ in the control group (P＜0.05).Conclusions DC-CIK cells combined with S-1 is a safe and effective treatment for non-small-cell lung cancer,which can effectively improve the clinical efficacy and prolong the survival time of patients.
