Objective To discuss the factors which are related with curative effects of endoscopic sinus sur-gery of sinusitis and nasal polyps. Methods 480 patients with rhinosinusopatia who were received endoscopic sinus surgery were retrospectively analyzed. Results The curative rate was 74.5% ,improved rate was 18.1% ,ineffective rate was 7.3%,the effective rate was 92.7%. Conclusion ESS is an effective method for the treatment of chronic sinusitis and nasal polyps. However,the therapeutic effects were closely related with the clinical types of lesion. Ap-propriate treatment to the diseased middle turbinate and deviated nasal septum during the period of surgery and effec-tive combined treatment after operation are very importint to the long-term therapeutic effects of ESS on these lesion.

Objective The purpose of this study was to evaluate the use of tracheo-oesophageal vioce prostheses after total laryngectomy.Methods Between 1995 and 1999,18 male patients ,Aged from 42 to 68,average 54.6,used Blom-singer voice prostheses after total laryngectomy.10 cases were glottic style,8 cases were subglottic style.12 patients received stage I,6 patients received stage Ⅱ voice reconstruction surgery. Results All cases were followed-up from 3 to 5 years. The success rate was 77.8%(14/18). The time with prostheses ranged from 8 to 19 months(average 12months). All failures were stage Ⅱ surgey .Conclusion Stage I voice reconstruction surgery can be performed in all total laryngectomy patients. But the indications of stage Ⅱ voice reconstruction surgery should be controlled strictly. More attention should be paid to the training of voice rehabilitation after total laryngectomy. The tracheo-oesophageal voice prostheses is an effective method to improve the life quality of the patients.

Objective To investigate the effect of CXCL16 on the development of murine collageninduced arthritis (CIA). Methods CXCL16 mRNA of the involved synovium and serum CXCL16 protein were determined respectively by reverse transcription-polymerase chain reaction (RT-PCR) and enzyme linked immunosorbent assay (ELISA) in murine collagen-induced arthritis. The proliferation of lymphocytes from murine spleen and the level of RANKL mRNA, stimulated by CXCL16 at different concentrations (0,100, 200, 400, 800 ng/ml), was detected respectively by CCK-8 and RT-PCR, then the level of IL-2 and IFN-γ in culture supernatant was detected by ELISA. Comparisons between groups were tested by t test and one-way ANOVA analysis. Results The serum CXCL16 [(127± 10) vs (72±8) pg/ml, P＜0.05] and synovial CXCL16 mRNA (0.214±0.007 vs 0.375±0.009, P＜0.01) in CIA were all significantly higher than those in normal controls. The proliferation of CXCL16 (200, 400, 800 ng/ml) in CIA mouse lymphocytes, was significantly higher than that of CXCL16 (0 ng/ml) (0.51±0.06, 0.56±0.05, 0.55±0.04, (0.41±0.04, P＜0.05). And CXCL16 on the CIA stimulated lymphocyte proliferation was significantly higher than controls on normal lymphocytes (P＜0.05). Compared with blank control group, the expression of IL-2, IFN-γ and RANKL mRNA of CIA CXCL16 (400, 800 ng/ml) groups was higher significantly (P＜0.01). Conclusion CXCL16 plays an important role in the development of murine CIA by activating lymphocytes.

Objective:To analyze bone strength index, osteoporosis and fracture in ankylosing spondylitis (AS) patients with radiologic hip involvement and explore the characteristics of bone strength in these patients.Methods:According to bath ankylosing spondylitis radiology hip index (BASRI-hip) score, 339 AS patients were divided into two groups. The differences of bone strength in each group were analyzed by t-test, Mann-Whitney U test and χ2 test. Logistic regression was used to analyze the risk factors of bone strength index. The correlation between quantitative ultrasound and dualenergy X-ray absorptiometry (DXA) (total hip, g/cm 2) was analyzed. Pearson correlation analysis was used. Results:①Bone strength index of quantitative ultrasound was positively correlated with bone mineral density of DXA (total hip, g/cm 2), r=0.553, P<0.01. ② The age of 27(23, 37) years old in radiographic hip involvement was lower than 37(28, 48) years old in non-radiographic hip involvement, and the difference was statistically significant ( Z=-5.986, P<0.01). There were no differences in gender and course of disease between the two groups ( P>0.05).③ The radiographic hip involvement in AS patients whose ages were younger than 50, when compared with non-radiographic hip involvement patients, the bone strength index was lower (78±18 vs 84±16), while bone strength was lower than patients at the same age (41.0% vs 18.4%), however, the incidences of osteoporosis (42.7% vs 28.8%) and fragility fracture (3.7% vs 0%) were significantly higher ( t=3.028, P<0.01; χ2=16.758, P<0.01; χ2=5.886, P=0.019; χ2=4.67, P=0.038). For AS patients whose ages were ≥50, there were no significant differences between the two groups ( P>0.05). ④ Multivariate analysis showed that radiographic hip involvement [ OR (95% CI)=1.912(1.05, 3.48)], age [ OR (95% CI)=0.94(0.911, 0.97)] and body mass index (BMI) (kg/m 2) [ OR (95% CI) =0.875(0.807, 0.948)] were associated with lower bone strength. Conclusion:There is positive correlation between the bone strength index of quantitative ultrasound and bone mineral density of DXA. AS patients with radiographic hip involvement are characterized by decreased bone strength and are more likely to develop osteoporosis and fragile fractures. The risk factors of low bone strength are radiographic hip involvement, age and BMI.

Objective To analyze the outcome of intra-artery chemotherapy for T1G3 bladder cancer , and its effectiveness and safety. Methods From June 2003 to May 2014, 39 patients with T1G3 bladder cancer chose intra-artery chemotherapy (Gemcitabine plus cis-platin), and close follow-up was required after 2 cycles of chemotherapy. During the follow-up, transurethral resection of bladder tumor was performed for non-muscle invasive bladder cancer, and cystectomy was performed for muscle invasive tumor. Results Of all patients, 32 were male and 7 were female. The median age was 56 years old (range: 32-82 years), and median follow-up time was 56 months (range: 12-136 months). Nineteen patients were primary bladder cancer, and 20 were recurrent tumor. During the follow-up, 17 patients developed recurrent tumors, including 8 progressed tumors and 3 died from tumor. Two-year and 5-year progressed-free survival were 88% and 74%, and 2-year and 5-year cancer-specific survival were 97% and 89%, respectively. During 5 years′ follow-up, 81% survivor preserved intact bladder, and only 1 patient cancelled chemotherapy for adverse effect. Conclusions Intra-artery chemotherapy (GC regimen) is a choice for T1G3bladder cancer, preventing from disease progression with good tolerance.

Objective:To explore the influence of blood transfusion on cellular immunofunction in patient with laryngeal carcinoma.Method:EPICS-XL flow cytometry was used to measure T cell subgroup,NK cell and CD28 in 36 patients with laryngeal carcinoma pre-operation and 2 weeks post-operation.Patients were divided into allotransfusion group and non-transfusion group.Comparison was conducted between the 2 groups.Result:①Comparsion with normal population,decreasing of CD3,CD4,NK cell and CD28 in the 36 patients pre-operation was statistically significant (P＜0.01).②Decreasing of CD3,CD4,NK cell and CD28 was statistically signficant post-operation(P＜0.05).③In the non-transfusion group change of CD3,CD4,CD8,NK cell and CD28 post-operation was statistically insignificant (P＞0.05).Conclusion:While cellular immunofunction is generally low in patients with laryngeal carcinoma,allotransfusion will reduce further.It makes contribution to spreading and metastasis of carcinoma easier.

13 C isotopic abundance of intracellular free amino acid with a characteristic of fast- turnover can quickly reflect changes in intracellular metabolic state. But the concentration of intracellular free amino acid is low, the existed 13 C isotope detection method based on GC-MS can not satisfy the requirement with full scan mode. In this study, the selected ion monitoring method was used to detect accuracy higher likelihood of analysis of 13 C isotopic abundance of free intracellular amino acid. First, in the full scan mode we analyzed of the fracture law of different amino acids, found the feature corresponding to each amino acid fragments, and established 16 kinds of free intracellular amino acids characteristic fragment library. Then using this characteristic fragment library, only specific m/z signal was detected in sample analysis, which realized the selected ion monitoring and improved the quality of signal. The results of amino acid standards showed that the signal-to-noise ratio, measurement precision and accuracy were improved by 17, 2. 0 and 3. 8 times compared with the full scan mode. In the analysis of coenzyme Q10 producing strains of samples, this method was successfully used to detect isotopic abundance of 8 kinds of free intracellular amino acids. This method plays an important role in the detection of 13 C isotopic abundance of the intracellular free amino acid in cell metabolism research.

A method for measuring 13C isotopic abundance of intracellular metabolites of Saccharopolysporaerythraea by ultra-high performance liquid chromatography (UPLC)-triple quadrupole mass spectrometry was established.First, the chromatographic conditions of UPLC were optimized, and then the MS conditions such as unique tube lens voltage, collision energy, and ion pair were optimized.On the bases of length of the parent and daughter ions carbon chains and whether the daughter ions contain 13C atoms, the one-to-one method, one-to-many method and SIM method were established for measuring 13C isotopic abundance.Then these methods were used to measure naturally labeled intracellular metabolite standards and 13C labeled samples, and according to the gap between the experimental value and the theoretical value, the best method was established for each metabolite of different characteristics.The results showed that one-to-one method was most effective for measuring the metabolites of daughter ions not containing 13C atoms represented by sugar phosphates, one-to-many method was the best for measuring the metabolites of both parent and daughter ions containing 13C short carbon chains represented by carboxylic acids, SIM method could play a role in measuring the metabolites of both parent and daughter ions containing 13C long carbon chains represented by coenzyme A.This method had a good measurement precision and could be applied to the measurement of Saccharopolysporaerythraea intracellular metabolites, which contributed to the consequent study of metabolic mechanism and the efficient expression of erythromycin.
