Objective To investigate the clinical value of HLA-B27 testing in diagnosis of ankylosing spondylitis (AS) by flow cytometry. Methods The peripheral blood HLA-B27 was detected by flow cytometry in 75 diagnosed AS patients (AS group), 95 suspected AS patients (non-AS group) and 45 health people (control group). Results The fluorescence intensity and the positive rates of HLA-B27 in AS group were significantly higher than those in non-AS group and control group: 158.0 ±24.0 vs. 94.8 ±30.5 and 89.1 ±18.9, 93.33% (70/75) vs. 5.26% (5/95) and 4.44% (2/45), and there were statistical differences (P<0.05). The sensitivity of HLA-B27 in diagnosis of AS was 93.3% (70/75), the specificity was 94.7%(90/95), while the accuracy was 94.1%(160/170). Conclusions There is a high correlation between AS and HLA-B27. The flow cytometry assay of HLA-B27 plays an important role in the early diagnosis and differential diagnosis of AS.

One hundred seventy of patients with cervical esophageal carcinoma (30 cases were treated by pre-operative radiation and surgery (combined group), 27 cases by surgery alone, 113 cases by radical radiation). The doses of the preoperative radiation and the radiacal radiation were D T40 Gy/4w and above D T 50 Gy/5w, respectively. The 5 year survival rates were 40% in the combined group, 15.3% in surgry alone, and 28% in radical radiation groups. The difference of survival rates in the combined group and surgery alone was significantly different statistically. Factors affecting the survivals were lymphnode metastasis in radical radiation and recurrent larygeal nerve paralysis in the combined group. The main causes of failure were local residual and recurrence (71%) in radical radiation and lymphnode metastasis (81%) in the combined group. The authors believe that pre-operative radiation combined with surgery could improve the survival of cervical esophageal carcinoma. Radical radiation is also one of effective treatment methods for cercical esophageal carcinoma.

The prognosis is very poor for the patients with advanced esophageal cancer proved by explored operation.There was not concurrent for the value of radiotherapy after explored operation.A series of 104 patients with explored operation alone and 155 patients with radiotherapy before or after explored operation were analyzed to evaluation the value of postoperetive radiotherapy. The results showed: (1) Postoperative radiotherapy was effective for the patients with advanced esophageal cancer after explored operation.The average survival/mean survival and 1～5 years survival were higher in the patients with postoperative radiotherapy than in those of operation alone. (2) ≥6000cGy groupe was better than

Objective To investigate the predictive value of symmetrical ambulatory arterial stiffness index (S-AASI) in detecting early renal impairment of patients with essential hypertension.Methods Totally 245 consecutive out-patients were confirmed with essential hypertension,and were divided into group A (56 cases),group B (64 cases),group C (72 cases),and group D (53 cases) according to the quartile of S-AASI.The combination testing of serum cystatin C,serum β2-microglobulin as well as urine microalbumin to creatinine ratio were implemented as laboratory diagnosis index of renal impairment in early stage and 109 essential hypertension patients were diagnosed with early renal impairment.The parameters were compared among 4 groups.Pearson correlation analysis and partial correlation analysis were performed to confirm the relationship between the markers of early renal impairment and S-AASI.The predictive value of S-AASI to detect early renal injury was evaluated by analyzing Receiver Operating Characteristic (ROC) curve.Results With the rising of S-AASI,age as well as 24 hours mean systolic blood pressure (24 h SBP),serum cystatin C,serum β2-microglobulin,urine microalbumin to creatinine ratio and the incidence rate of early renal injury went notably higher while estimated glomerular filtration rate (eGFR) decreased significantly.After controlling for age,correlation test showed S-AASI was positively correlated with24hSBP,serum cystatin C,serumβ2-microglobulin,urine microalbumin to creatinine ratio(r =0.392,0.627,0.514 and 0.643 respectively,P ＜ 0.05) and negatively correlated with eGFR(r =-0.312,P ＜ 0.05).The 24 hours mean diastolic blood pressure (24 h DBP) was uncorrelated with S-AASI.Area under ROC curve of S-AASI for diagnosis of hypertensive renal impairment was 0.885.The critical value of S-AA-SI was 0.17,the sensitivity,specificity,positive predictive value,and negative predictive value were 92.7％,65.2％,68.5％,and 91.7％,respectively.Conclusions When S-AASI was detected above 0.17,patients with hypertension had a higher risk of renal impairment.Higher S-AASI was correlated with worse early renal impairment laboratory indexes.The predictive accuracy of S-AASI for early hypertensive renal impairment was medium.

OBJECTIVE: To study on clinical significance of acoustic rhinometry and nasal resistance checks by low temperature radiofrequency ablation on nasal endoscopy operation. METHOD: Application instrument of acoustic rhinometry and nasal resistance meter on 106 cases with moderate to severe persistent nasal obstruction symptoms. These patients are not obvious or invalid after regular drug treatment. The preoperative and postoperative six months, with the nasal mucosa contraction before and after by inspect respectively,also record nasal resistance (NR), nasal minimum cross-sectional area (NMCA), distance of the minimal cross-sectional area to the nostril (DCAN), mean nasal cross-sectional area (MNCA), nasal cavity from volume (NCV). The other 36 cases of healthy people as a control group. Before and after nasal mucosa contraction by inspect. Two sets of data were statistically analyzed with SAS6.12. The efficacy evaluation of radiofrequency ablation by improve the extent and visual analog scale (VAS) score, with the patient's subjective symptoms. RESULT: The group of preoperative rhinitis treatment NR higher than the controls significantly, the NMCA significantly lower than the control group (P< 0.01). The group of postoperative by radiofrequency ablation and rhinitis treatment was 100%, postoperative VAS scores were decreased compared with pre operative (P < 0.01). The group of rhinitis treatment NR was significantly lower than the preoperative, and NMCA significantly increased compared with the preoperative (P < 0.01). Before and after nasal contraction in the same group, NR and NMCA was no difference (P > 0.05). The NR and NMCA of the postoperative in rhinitis treatment group was no difference compared with the control group (P > 0.05). CONCLUSION Low temperature radio frequency ablation by nasal endoscopy operation had a significant improvement of nasal ventilation functions for patients with moderate to severe chronic rhinitis, acoustic rhinometry and nasal resistance can be an objective and accurate evaluation to this operation.
