Chinese Archives of Otolaryngology-Head and Neck Surgery 2001;8(2):76-77
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.

Objective To investigate self-management status of the DM patients,and to confirm scientifically the importance of emphasising diabetes education in the DM patients.Methods With the questionnaire on self-management status & the possessed degree of DM knowledge and the method of consulting the medical records,697 DM patients were investigated.Results There were about 47.20% of patients who did not take glycemic examination in one year.Awareness rates for the standards of blood lipids and the HbA_1C were 6.5% and 5.5% respectively.And the awareness rates for nutrition treatment principle and scientific mode of physical exercise were 30.3% and 21.8%,respectively.The prevalence of The DM complications was the highest in the cadre(29.52%) and the lowest in the peasants(3.59%).Conclusion The investigation revealed the self-management is imperfect and the DM knowledge in DM patients is insufficient.It should be accentuated for patients to take health education of DM knowledge and improve their level of self-management.

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.

Objective: To observe the characteristic changes of specific immunological function of serum endo toxin level,spleen lymphocyte human leukocyte antigen(locus) DR(HLA-DR),limphopolesis and positive expression of caspase-3 in rats with sepsis and the effect of Xuebijing injection(血必净注射液) on their immunological function.Methods: Sepsis model was produced by cecal ligation and puncture(CLP).Seventytwo male SD rats were randomly divided into four groups: sham operation,model,levofloxacin and Xuebijing injection.Blood samples were taken from the vein in the abdominal cavity at 3,24 and 72 hours after the models were established, afterwards the rats were sacrificed and their spleens were taken out.Matrix development process was employed to examine the level of serum endotoxin,FACS flow cytometer was used to examine the expression level of HLA-DR,immunohistochemistry method was applied to examine the positive expression of caspase-3 in spleen,and the method of methyl thiazolyl tetrazolium(MTT) was employed to examine the lymphopoiesis.Results: The levels of serum endotoxin,lymphopoiesis and caspase-3 positive expression index in model group were obviously elevated than those of sham operation group,and percentage of HLA-DR was markedly lowered(all P

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.
