OBJECTIVE To investigate the two treatment methods for obstructive sleep apnea hypopnea syndrome(OSAHS)patients.METHODS 1.Four patients with habitual snoring and two patients with mild OSAHS accepted pillar palatal implant.2. Eleven patients with habitual snoring and fifteen patients with mild to moderate OSAHS accepted temperature- controlled bipolar radiofrequency(RF)ablation in both tonsils.RESULTS The postoperative examination was performed after 6 months.Pillar palatal implant: snoring VAS was reduced from 6.9?0.68 preoperatively to 3.8?0.54 postoperatively in 4 patients with habitual snoring,snoring VAS was down from 9.2?1.21 to 3.1?0.52 in 2 patients with mild to moderate OSAHS.Seven of 11 cases with habitual snoring were cured by RF,and 2 cases were effective,the other 2 cases were failed. Ten of fifteen cases with mild to moderate OSAHS were cured,3 cases were effective,and 2 cases were failed. The effective rate was 84.6%(22/26).CONCLUSION 1.The pillar palatal implant system is a safe method for patients with simple snoring and mild OSAHS in a short time observation.2.Temperature-controlled bipolar radiofrequency ablation is effective for mild to moderate OSAHS duo to hypertrophy of the tonsils.3.According to the clinical characteristics of the patients to select suitable method is the key to get a satisfactory curative effect.

ObjectiveTo discuss etiology, pathology, clinical manifestations, diagnosis, management and prognosis of cavernous degenerarion and hypertension of portal vein.MethodsThe clinical and image data of 7 children with cavernous degeneration and hypertension of portal vein were veviewed.ResultsHematemesis, melena and splenomegaly were the major presentations. The diagnosis was confirmed by color Doppler ultrasonography except 4 cases had angiography. All cases underwent splenectomy and transection of the gastric fundus and esophageal veins. Five of them had an additional portalcaval shunt.ConclusionCongenital factors may play some role in the development of cavernous degeneration and hypertension of portal vein in children. For the disase discussed this paper the image examination is the main diagnostic method, and the management is same with portal hyertension and the prognosis is closely related to the liver function.

Two reaction systems have been observed to ascertain the capability of ABC-ELISA on the detection of antibodies against particulate antigens.Mouse thymucytes as the antigens were coated on the enzyme immunoassay plate for one system,and rabbit anti- mouse brain serum was titrated.The titer of the serum in ABC-ELISA was 1:12,800, about 40-fold higher than that in complement dependent cytotoxicity assay.In the other system,the plate was coated with cultured human leukemia cells of T lymphocyte origin(Cem-T)and B cell origin(Daudi),where the ascites induced by an anti-human lymphocyte hybridoma was titrated.The results showed that ABC-ELISA was 8-16 times sensitive than the standard ELISA,while the specificity and reliability of ABC- ELISA seemed satisfectory.The experi mental condition that might reduce nonspeci- ficity of the reaction to a certain degree was discussed.

Objective To investigate the effect of reconstruction for inferior pharyngeal and cervical esophagus defect with inferior antebrachial skin flaps on the living quality of patients after surgery. Method Perform radical operation of the tumor, but retain larynx and trachea. Free antebrchial skin flaps were used to reconstruct the defect of inferior pharynx and cervical esophagus. Roll the skin flap to form a skin tube, and then carry out anastomosis with floor of mouth and cervical esophagus. Result The laryngeal function was retained after surgery. And permanent orifice of trachea was unnecessary. The effect was satisfying. The vocalization wasn't affected and food- intake through oral was normal in the 2 patients followed up. Conclusion It is a feasible way to reconstruct the inferior pharynx and cervical esophagus defect caused by radical operation of the tumor at pharynx and cervical esophagus. It can improve the living quality of patients effectively.

Objective The present study investigated the expression of the citrullinated proteins in the synovium and serum of rheumatoid arthritis(RA)patients.Methods The expression of the citrullinated proteins in the synovium and serum of RA patients was analyzed by two-dimensional western blotting analysis (2-D WB),mass spectrometry MALDI-TOF/TOF MS,western blotting,immunohistochemistry and ELISA.Then we analyzed the data with one-way ANOVA,LSD test,Kruskal-Walls test and Spearman correlation analysis.Results Alpha-1-antitrypsin(A1AT),fibrinogen beta chain(FIBB),keratin type Ⅱ cuticular Hb4(KRT84),tubulin beta chain(TBB)and vimentin(VIME)were detected in RA serum and anti-citrulline antibody could be detected using 2-D WB.A1AT,KRT84 and TBB were expressed significantly in the synovial membranes and synovial fluids of RA patients.Furthermore,high levels of autoantibodies against KRT84 were detected in the blood of RA patients when compared with samples from the healthy controls.Conclusion Current study has identified novel autoantigens in RA,including A1AT,FIBB,KRT84,TBB and VIME using 2-D WB with purified RA sera and anti-citrulline antibody.FIBB and VIME have been confirmed to be autoantigens in the literature,this demonstrates the feasibility of our protocol and the reliability of our study results.

A male patient, 41 years old, swallowed a chunk of muskmelon because his attention was not centralized. Odynophagia and dysphagia were the two main clinical manifestations. The esophagus barium swallow examination showed a foreign body in the upper esophagus. The patient did the rigid esophagoscope examination in the operating room under general anesthesia. There was a chunk of muskmelon in the upper esophagus and could not take it out from the esophagus by using foreign body forceps because the muskmelon was very crisp. In the end the muskmelon was sent in the stomach. The patient's symptoms were alleviated after operation.

Objective Carbonic anhydrase 1 (CA1) not only enhances the hydration reaction but also promotes the formation of CaCO3,which is an essential step for new bone formation in vitro.However,there is no direct evidence to demonstrate the involvement of CA1 in bio-mineralization in cells and tissues.This study is aimed to evaluate the important role of CA1 in bio-mineralization and ossification in cultured cells.Methods Calcification in Saos-2 cells was induced using osteogenic medium (OM) and the calcification was determined by Alizarin Red-S staining.The expressions of ossification protein marker Runt-related transcription factor-2 (Runx2),osterix (OSX),alkaline phosphatase (ALP),osteocalcin (OCN) and bone sialoprotein (BSP) were detected in the process of bone formation by real-time PCR.The expression of CA 1 in the calcified cells were measured using real-time PCR and Western blotting.We also detected calcification in Saos-2 cells in the presence of acetazolamide,an anti-carbonic anhydrase drug to CA1,to determine the role of CA1 in biomineralization in culture cells.T test analysis was used to compare the two groups,M-ANOVA of repeated measurs was conducted for different time point.Results Following the stimulation of OM,Saos-2 cells produced a great amount of calcium-rich deposits [0.68±0.03 vs 2.76±0.13,P＜0.01].Increased transcriptions of ossification protein markers were also detected in these stimulated Saos-2 cells,indicating that the OM launched the process of bone formation in the cells.CA1 had a significantly increased expression during this process [0.25±0.03 vs 0.94±0.06,P＜0.01].Following treatment with acetazolamide,the expression of CA1 evidently declined [1.09±0.05 vs 0.55±0.07,P＜0.05],and the mineralized nodule formation was declined [2.76±0.13 vs 2.19±0.07,P＜0.01].Conclusion These findings indicate that CA1 participates in the biomineralization and ossification,and may play an important roles in bone formation.
