Objective To evaluate the subjective and objective improvement of quality of life in patients with low-temperature plasma-assisted modified uvulopalatopharyngoplasty (H-UPPP) combined with lymphoidectomy in radix lin-guae and coblation-channeling of the tongue(CCT) treating for severe obstructive sleep apnea hypopnea syndrome (OSAHS) , and compare the surgical efficacy with that of H-UPPP. Methods A total of 81patients with severe OSAHS were divided in-to treatment group (n=42) and control group (n=39). Treatment group underwent the low-temperature plasma-assisted H-UPPP combining lymphoidectomy in radix linguae and CCT,and control group underwent H-UPPP treatment. The apnea hy-popnea index (AHI), the lowest saturation of arterial oxygen (LSaO2) and Quebec sleep questionnaire (QSQ) and Epworth sleepiness scale (ESS) before operation and 6-month after operation were recorded and compared between two groups. Re-sults All of detection indicators were significantly improved after operation in treatment group (P＜0.01). The total surgical efficacy was significantly higher in treatment group than that of control group (83.3%vs 12.8%,χ2=40.225,P＜0.01). The to-tal improvement rate of five dimensions in QSQ such as daytime sleepiness symptoms (76.2%vs 25.6%), signs during the day (71.4%vs 10.2%) and night (54.8%vs 5.1%), emotion (54.8%vs 2.5%), ability of social intercourse (50.0%vs 2.5%) and the total score (57.1%vs 7.7%) after operation were significantly higher in treatment group than those of control group. The se-vere indexes of ESS decreased to 23.8% after operation in treatment group than those of control group (51.3%). Conclu-sion Low-temperature plasma-assisted H-UPPP combined with lymphoidectomy in radix linguae and CCT is effective in patients with severe OSAHS, which can also improve the quality of life postoperatively.

OBJECTIVETo summarize the clinical characteristics of an infant with chronic myelogenous leukemia (CML) and the effects of imatinib on the case.

METHODThe clinical features of an infant with CML, who was treated with imatinib in the Norman Bethune International Peace Hospital at June 2009, were retrospectively analyzed and the reports in literature were reviewed. The 1-year-old boy suffered from recurrent low-degree fever and pallor. He had a moderate anemia, distended abdomen and marked splenomegaly. Bone marrow aspiration revealed CML in chronic phase)CP). The t (9; 22))q34; q11) could be detected and BCR-ABL (p210) was positive. The boy was diagnosed as CML-CP and treated with imatinib 100 mg per day. There were 10 related papers and more than 100 child CML patients were reported as retrieved from CNKI)from its establishment to August 2014) and Wanfang Database)from its establishment to August 2014) when "Child", " Chronic" and "Leukemia" were used as keywords. And there were 30 related papers including 400 cases from PubMed Database (from its establishment to August 2014) and one detailed report of an infant with CML was retrieved when "childhood" and "chronic myeloid leukemia" "imatinib" were used as keywords. The clinical effects of imatinib in infant CML cases were analyzed and summarized based on the literature.

RESULTThe boy obtained a complete hematologic response (CHR) at the 6th week of diagnosis, a complete cytogenetic response (CCyR) at the 3rd month and a complete molecular response)CMR) at the 12th month without side effect. This boy grows very well and after a 62-month follow-up, his disease was stable. According to the domestic literature, 5 children CML cases aged 6 -12 years were treated with imatinib without side effects and got complete hematologic response (CHR) after 2-month-therapy. The dose, metabolic characteristics and clinical observation of imatinib can be found in foreign literature and imatinib showed good response with good tolerance in children with CML. Imatinib is regarded as the first line drug for children CML. But it may affect the development of the children.

CONCLUSIONThe children with CML-CP had a good response to imatinib, but more experience in the treatment of children with CML with iniatinib is needed.

Objective To investigate the expression and clinical significance of p63, CD_(44v6) and human papilloma virus (HPV) 16/18 in carcinoma of cervix and precancerous lesion and to study their role in the pathogenesis of the infiltrative carcinoma of the cervix(ICC). Methods 145 patients were selected, among whom were 60 cases of ICC, 55 cases of cervical intraepithelial neoplasia (CIN) and 30 cases of normal cervical epidermis (NCE). Immunohistochemistry streptavidin peroxidase (SP) was used to detect the expressions of p63 and CD_(44v6) protein and hybridization in situ was used to measure HPV 16/18 gene on tissue microarray. Results HPV 16/18, p63 and CD_(44v6) in ICC were significantly higher than those in CIN and NCE groups (P < 0.05). The expressions of HPV 16/18 gene in CIN I 、CIN II and CIN III were 27.3 % , 43.8 %, 70.6 % respectively. p63 protein was mainly expressed in squamous cell carcinoma, but not in adenocarcinoma. p63-positive rate was related to the grade of squamous cell carcinoma and clinical stage. CD_(44v6) positive rate was related to the pathological grade and clinical stage. Moreover, the positive rate of lymph node metastasis was significantly higher than the cases without metastasis (P <0.05). The expression of HPV16/18 was positively correlated with that of p63 in ISCC (P <0.05, Cp =0.49). Conclusion HPV16/18 possibly participate in the pathogenesis and progress of cervical squamous carcinoma. p63, as the cancer gene, may participate in the occurrence and development of cervical cancer caused by HPV 16/18. p63 could be a differentiation indicator of cervical squamous carcinoma, and it could be one of the markers which would be differentiated into squamous cell in malignant tumour. CD_(44v6) could be used as one of the indicators of distant metastasis of cervical cancer.

Objective To investigate the expressions and clinicopathological significance of 3q27-3q29-related p63 protein in diffuse large B-cell lymphoma (DLBCL). Methods An immunohistochemical Envision~(TM) method was used to detect the expressions of p53 and 3q27-3q29-related p63 protein in 102 cases of DLBCL and 15 cases of reactive hyperplasia of lymph node (RHL). Results The tumor cell expressions of p53(62 %) and p63(56 %) in DLBCL were significantly higher than that in RHL (0 and 13 % P < 0.05). The expressions of p53 and p63 were significantly different (1) between stage Ⅰ + Ⅱ (the positive rate 48.3 % and 41.4 %, respectively) and stage Ⅲ+Ⅳ(the positive rate 79.5 % and 75 %, respectively; P <0.05), (2) between GCB type (the positive rate 28 % and 28 %, respectively) and non-GCB type(the positive rate 72.7 % and 64.9 %, respectively; P <0.05). The expressions of p53 and p63 had no relationship to gender, age, B symptoms and locations. The expression of p53 was positively correlated with that of p63 in DLBCL (P <0.05, Cp=0.629). p53 and p63 protein expression in negative group the 5-year overall survival rate is higher than that in positive group (38 % and 6 %, 51% and 4 %, respectively), the difference was statistically significant (P <0.05). Conclusion It was likely that p63, as the oncogene, participated in the occurrence and development of DLBCL together with p53. Also, p63 and p53 might play a synergistic role in the occurrence DLBCL. Combined detection of 3q27-3q29-related 1963 protein and p53 protein in DLBCL, might be one of the indicators to the prognosis of DLBCL.
