Thirty-four patients with chronic lingual tonsillar hypertrophy were treated in our department from 1994 to 2000. There were 18 males and 16 females ranging in age from 21 to 60 years old. The clinical feature of lingual tonsillar hypertrophy usually appeared a series of pharyngeal symptoms, such as foreign-body sensation, sore throat, speech change, difficulty in swallowing, dysapnea and obstructive sleep apnea. The CO2 laser surgical lingual tonsillectomy was used for these patients. Result showed that the cure rate was 100% without any serious complications by following up 2 months to 3 years. The variety of presentations of lingual tonsillar hypertrophy and methods of surgical treament were discussed.

Objective To discuss the metabolic characteristics and significance of peripheral blood cell and T lymphocyte subgroup in patients with air condition disease.Methods Thirty-six patients diagnosed as air condition diseases with fever and 30 patients diagnosed as non-fever patients enrolled this study as observation group(fever group and non-fever group respectively),and 30 health population were used as control.The changes of peripheral blood cell and T lymphocyte was measured using regular blood examination and flow cytometry.Results(1)No significant diffence on white blood cell was found between the three groups(F =1.89,P =0.134);(2)The percentage of neutrophils was(68.13 ±5.67)％,(53.24 ±8.36)％ and(61.25 ±6.31)％ respectively in the fever,non-fever and control group,respectively.Compared to the non-fever and control group,the percentage of neutrophils were significantly higher(t =6.64,9.13; P =0.018,0.027 respectively).No signiciant difference in the percentage of neutrophils was found between the non-fever group and control group(P =0.356,0.125).The percentage of lymphocyte percentage was(31.66 ±7.11)％,in the fever group,which was significantly higher than those of(43.67 ±8.17)％ and(30.98 ± 8.76)％ in the nonfever and control group(t =5.59,4.98 ; P =0.022,0.021 respectively).(3)The percentage of CD4 + was (36.351 ± 6.531)％,(42.676 ± 5.169)％ and(39.253 ± 5.461)％ in the fever,non-fever and control group,respectively.The percentage of CD4 + in the fever group was significantly lower than that in the non-fever group(t =1.28,P =0.039),whereas the percentage of CD4 + in the non-fever group was significantly higher than that in the control group(t =3.80,P =0.048).The percentage of CD8 + was(28.084 ± 7.344)％,(21.186 ± 6.331)％ and(24.607 ± 7.108)％,respectively.Compared to nonfever group,the percentage of CD8+ was significantly higher(t =3.17,P =0.016).(4)The ratio of CD4 +/CD8 + was(1.629 ±0.554)％、(2.380 ± 0.391)％,and(2.079 ± 0.659)％.Compared to the non-fever and control group,the ration in the fever group was siginificantly lower(t =19.21,P ＜ 0.001 ; t =6.98 ; P =0.006),whereas compared to the control group,the ratio in the non-fever group was significantly higher(t =8.68,P =0.031).Conclusion The changes of T subgroup show the unbalance immunity function network in patients with air condition disease.

Biosplint splinting ribbons and flowable restorative were used to stabilize the mobile anterior teeth and replace the missed teeth with in 30 patients severe periodontitis.1 and 2 years after treatment the effective ratio was 86.7% and 83.3% respectively(P >0.05), probing depth and attchment loss were decreased(P <0.05).

Objective To analyze the clinical features of patients with hemophagocytic syndrome (HPS) in autoimmune diseases (AID). Methods We collected the data of 11 patients with AID complicated with HPS in Peking Union Medical College Hospital from 2004 to 2009. The underlying diseases, clinical features, laboratory findings and treatment outcomes were retrospectively analyzed. Results Of the 11 patients,3 were male,8 were female. Mean age was (30. 7 ± 18. 3) years. The underlying diseases included Still disease ( n = 4 ), systemic lupus erythematosus ( n = 3 ), and rheumatoid arthritis, primary Sj(o)gren's syndrome, Wegener granulomatosis and Crohn disease in each one case. HPS was associated with the onset of AID ( n = 4), active infection alone ( n = 1 ) and both factors ( n = 6 ). HPS was clinically characterized by high fever ( 100% ), hepatosplenomegaly ( 72. 7% ) , lymphadenopathy ( 63.3% ) and central nervous system involvement (36. 3% ). 4 patients presented with disseminated intravascular coagulation(DIC) (36. 3% ). Laboratory data mainly manifested with cytopenia ( 100% ), liver dysfunction ( 100% ), hypofibrinogenemia ( 62. 5% ), hypertriglyceridemia ( 81.8% ), serum ferritin ＞ 500 μg/L (100%), low NK-cell activity(80% ) and hemophagocytosis in bone marrow( 100% ). Based on treating underlying infections and use of corticosteroids and immunosuppressive agents in combination with intravenous immunoglobulins(IVIG) therapy, 5 patients recovered , 6 patients died. The mortality rate was 54. 5%. DIC were associated with mortality ( r = 0. 69, P = 0. 019 ). Conclusion The episode of HPS always occurs simultaneously with multiple system involvement that was often difficult to distinguish from active AID. The present of DIC on HPS related with poor prognosis and high mortality. Corticosteroids and immunodepressant and IVIG may improve the prognosis of HPS, while anti-infection therapy is very important and necessary for the patients accompany with active infection.

OBJECTIVE: To investigate the presence of vasculogenic mimicry in laryngeal squamous cell carcino- ma and explore its clinical significance. METHOD: The presence of vasculogenic mimicry and expression of endotheli- um-dependent vessel in 138 laryngeal squamous cell carcinomas cases were detected by the immunohistochemistry and tissue microarray. Metlab software was used to evaluate the relationship among vasculogenic mimicry, mi- crovessel density and clinic pathological parameters in laryngeal carcinoma. RESULT: We found vasculogenic mimicry in 32 (26.23%) of 122 laryngeal carcinoma samples. The mean of microvessel density is 12.61 per high-power field. The vasculogenic mimicry and expression of endothelium-dependent vessel were not significantly related to patient age or gender, tumor location, pathology grade, T stage or N stage (P > 0.05). However, the vasculo- genic mimicry and the mean of microvessel density were a little higher in patients older than 60, with poorly differ- entiated and patients with N₁₋₃ stage. Vasculogenic mimicry was positively correlatedwith microvessel density (r = 0.1927, P < 0.05). CONCLUSION Vasculogenic mimicry can occur in laryngeal carcinoma. Moreover, vasculogenic mimicry may be associated with recurrence and metastasis in laryngeal carcinoma.

Objective:To analyze the time consumption in the review of multicenter clinical trials and to explore the methods of improving the approval efficiency.Methods:We retrospectively analyzed 246 multicenter clinical trials approved by our hospital from 2012.Group A were trials that our hospital was the leading site while group B were those not.In group B,trials were divided into group B1 (conference review) and B2 (expeditedreview)according to the ethical review methods.Each group's ethical review time,contract signature time,starting experiment time,the total time consumption of review,and the time from the leading site approving to the participating site submitting application were analyzed.Results:In the review of multicenter clinical trials,contract signature cost the most time,accounting for 41％.There was no significant difference in terms of whether to be the leading site.The total time consumption of group B1 and group B2 was 180.94 days and 140.36 days (P ＜0.05),respec tively.The average ethical review time of group B1 was about 20 days longer than group B2 (P ＜ 0.01).There were 96.54 days that the leading site submitted review materials to the participating site after approved.Conclusions:In multicenter clinical trials,for those the leading site has already approved,immediate submission to participating site and choosing the expedited review method may improve the ethical review efficiency,thereby shorten the total approval time consumption.

Cognitive dysfunction is one of the complications of chronic obstructive pulmonary disease(COPD),often affecting the patient's daily life ability and reducing the quality of life.COPD associated cognitive dysfunction includes five areas of primary cognitive domain of awareness,attention,learning and memory ability,execution ability and language skills.The decreased cognitive dysfunction may be correlated with the age,education background,smoking,malnutrition,as well as hypoxemia,hypercapnemia,COPD duration and length of hospitalization stay,inflammatory and other factors.Early screening and assessment of COPD cognitive dysfunction,long-term oxygen therapy and other measures for interfering risk factors and improving the quality of life of patients have a positive significance.
