Objective To explore the relationship between adenoid vegetation children with different types of tympanograms and secretory otitis media in children and diagnosis of secretory otitis media .Methods A retrospec-tive study was carried out among 328 cases with adenoid vegetation in children ,including simple adenoid vegetation and associated with chronic tonsillitis and tonsillar hypertrophy ,from August 2010 to May 2012 .The incidence of secretory otitis media and outcomes of tympanometry for the diagnosis were analyzed .Results 104 cases were diag-nosed with secretory otitis media by tympanic membrane puncture or tympanostomy tube in 328 cases with adenoid vegetation (32 .31% );86 cases (147 ears) were finally diagnosed as secretory otitis media among 89 cases (152 ears) with type B tympanogram (147/152 ,96 .63% );16 cases (20 ears) were finally diagnosed secretory otitis media among 33 cases (49 ears) with type C tympanogram (20/49 ,40 .82% );2 cases (2 ears) with type As tympa-nogram were finally diagnosed .Conclusion With or without complaint of hearing loss ,children with adenoid vegeta-tion should be checked by routine tympanometry .Careful physical examinations and electric otoscope or ear endosco-py combined tympanometry can greatly reduce the rate of misdiagnosis of secretory otitis media .

Objective To explore the association of expression of apoptosis-associated gene BAK and cFLIP with the biological behaviors in endometriosis. Methods The expression of BAK and cFLIP protein gene in eutopic and ectopic tissue samples from 40 cases with pathologically confirmed ovarian endometriosis and 40 cases with pathologically confirmed normal endometrium was detected by immunohistochemical method. Results ①The expression of BAK and cFLIP protein gene was found in three groups of different endometrial tissue. ②The expression of BAK protein gene was increased gradually in ectopic endometrial , eutopic endometrium and normal tissue and there was significantly difference between every two groups ,while cFLIP was contrary expressed (P <0.05); ③In normal endometrium, The expression of BAK protein gene in secretory phase was higher than that in proliferative phase (P < 0.05), while cFLIP was contrary expressed, in eutopic endometrium and ectopic endometrial tissue , The expression of BAK and cFLIP protein gene in secretive phase showed no statistically significant difierence with that in proliferative phase (P > 0.05). ④The expression of BAK protein gene in severe group (Ⅲ-Ⅳ period) is lower than mild group both in eutopic or ectopic endometrial tissues,while cFLIP was contrary expressed (P < 0.05). ⑤The expression of BAK and cFLIP was negatively correlated with each other in ectopic endometrium (r=-0.389,P< 0.05). Conclusion BAK and cFLIP was negatively expressed in EMS, which may take a part in the endometrial apoptosis and disorderly proliferation. BAK and cFLIP may play an important role in the the diagnosis and treatment of endometriosis.

Objective To identify the risk factors for progression of advanced chronic kidney disease(CKD) patients who were cared by nephrologists in a specific CKD outpatient management clinic.Methods A prospective monocentric cohort study was performed.CKD patients of stage 3, 4 and 5 without renal replacement treatment were followed up regularly by nephrologists in this specific CKD management clinic.Patients with established atherosclerotic renal artery stenosis(ARAS) and chronic tubulointerstitial nephritis, and those who had not been followed-up for at least 12 months before Jun.30, 2010 were excluded.Clinical and laboratory data including blood pressure (BP), proteinuria, hemoglobulin (Hb), calcium phosphate product (Ca×P) and serum creatinine were consecutively collected.The treatment regimen was also recorded.Estimated glomerular filtration rate(eGFR) was calculated with the formula modified for Chinese to evaluate the change of renal function.The progression of kidney disease was defined as initiation of renal replacement therapy, the annual decrease of eGFR＞4 ml·min-1·(1.73 m2)-1, and/or death associated with renal disease.Results A total of 138 patients were enrolled in the final analysis with 84 patients of CKD stage 3, 36 of CKD stage 4 and 18 of CKD stage 5, respectively.At the time of enrollment, patients had an average age of (56.5:±:16.7) years old with an average eGFR of (32.3±13.4) ml·min-1·(1.73 m2)-1.During a mean follow-up interval of (27.1±12.1) months, the patients were well-controlled with an average blood pressure of (126.5±12.4)/(76.4±7.9) mm Hg in 50.7％(70/138), less than or equal to 130/80 mm Hg, an average Hb of(123.8±17.1) g/L in 73.9％(102/138), above or equal to 110 g/L and an average Ca×P of (45.2±7.7) mg2/dl2 in 89.1％(123/138), less than or equal to 55 mg2/dl2.Sixty-two patients (44.9％) had progression of kidney disease. On univariate analysis, factors predicting progression were low eGFR at referral, high systolic pressure, low Hb level, high Ca×P and proteinuria during follow-up, and renin-angiotensin system inhibitors treatment did not affect the progression.After the adjustment, multivariate analysis revealed proteinuria and low Hb level were independent factors for the progression of kidney disease.Conclusions The co-morbidities of advanced CKD patients can be managed efficiently in specific CKD outpatient management clinic.Control of proteinuria and correction of anemia may be beneficial to prevent the progression of advanced CKD.

One day after the treatment stopped, the mice were sacrificed and the tumor masses were taken out and weighed. RESULTS: The inhibition rates of Longzhi extracts on the tumor of transplanted H22 and S180 were 63% and 41% respectively. CONCLUSION: Longzhi extracts has antitumor action.

Objective To study the effect of siRNA targeting bcl-2 gene on the drug-sensitivity of HL-60 cell to homoharringtonin(HT). Methods siRNA, selected by previous experiments and packaged with lipofectamine 2000, was transferred into HL-60 cells. Six hours later, the cells were cultured with homoharringtonin. The cell growth of HL-60 cells was detected by MTT methods at 24, 48, 72 hours respectively. The level of bcl-2 protein and ROS (reactive oxygen species, ROS) as well as membrane potential of mitochondrion was determined by flowcytometry. Results The siRNA could significantly increase the inhibitive effect of homoharringtonin on growth of HL-60 cells. The combination of siRNA with homoharringtonin resulted in the falling of bcl-2 protein level and rising of ROS level as well as descending of membrane potential of mitochondrion of HL-60 significantly (P
