[Summary] Chronic suppurative otitis media affects patients ’ quality of life, and is life-threatening in patients with cholesteatoma which causes intracranial or extracranial complications .The purpose of surgery is to clear up all the lesions and to reconstruct hearing function .Tympanoplasty is the main surgical method , which includes basically canal wall down ( CWD) and canal wall up (CWU) styles.CWD provides lager surgical field but impairs normal auditory canal structure ; CWU preserves the posterior wall of external auditory canal and provides better quality of life although it has higher possibility of recurrence of cholesteatoma .We reviewed the surgical methods , surgical effects , recurrence rates , and surgical indications of canal wall up mastoid-tympanoplasty , hoping to provide meaningful reference for clinical application .

Objective To study the detection and significance of human papillomaviral DNA(HPV-DNA) in cervical disease. Methods The express of HPV-DNA were detected by hybrid capture 2 in the patients with chronic cervicitis ( n = 166), cervical intraepithelial neolasia ( GIN ) ( n = 89 ) and uterine cervix cancer ( UCC ) ( n = 23 ). Results The positive expression rate of HPV-DNA in GIN Ⅰ , Ⅱ , Ⅲ grade and UCC were 70.8% (17/24) ,79. 3% (23/29) ,88.9% (32/36) ,91. 3% (21/23). They were significantly higher than those in chronic cervicitis 30.7% (51/166) (P ＜ 0. 01 );As the development of cervical disease, HPV-DNA positive expression had increasing trend.Conclusion The detection of HPV-DNA had an important role for the early UCC screening,prevention and treatment.

From 1952 to 1990, 21 cases of malignant tumor of the appendix, including 14 cases of carcinoid tumor of appendix, 4 cases of appendix adenocarcinoma, 2 cases of appendix lymposarcoma and 1 case of appendix cystocarcinoma, were treated in the Affiliated Hospital of Wannan Medical College Among these 21 patients, 16 underwent appendectomy alone, 5 underwent appendectomy first and a right hemicolectomy was performed on later All of the 21 patients were followed up for 5～10 years,the survival rate was 90 5% and 90 5% respectively So if a malignant tumor of the appendix was suspected, a biopsy during operation should be done to determine the pathological type If the diagnosis was clear, the choice of operation mode must be made according to the size and the pathological type of the tumor In selective patient, a right hemicolectomy must be performed on

Dysregulation and activation of immune processes are important in age-related macular degeneration (AMD) pathogenesis.The single nucleotide polymorphism of complement factor H is widely recognized as a risk factor to AMD.Over-activation of nod-like receptor3 and polymorphism of Toll-Like Receptor 3 also associated with AMD.Except for innate immune processes,adaptive immunity also play a critical role in AMD,a growing body of evidence supports that auto-antibodies and T cells are related with AMD.Additionally A2E and lipid oxidation byproducts might also have a role in AMD pathogenesis.

Objective To prepare paclitaxel-loaded poly(ε-caprolactone)(PCL)/pluronic F68(F68)blend microspheres as a controlled release system. Methods Paclitaxel-loaded PCL/F68 blend microspheres were prepared by the oil-in water(O/W)emulsion/solvent evaporation method. Characterization of the microspheres followed to examine the particle size, the drug encapsulation efficiency, the surface morphology, in vitro release behavior and DSC analysis. In vivo antitumor activity of paclitaxel-loaded PCL/F68 blend microspheres was evaluated in mice bearing with hepatoma H22 cells ascites tumor. Results The results showed that the porous structure can be formed in the surface of PCL/F68 blend microspheres. Faster and controlled release of paclitaxel from PCL/F68 blend microspheres was achieved in comparison with the PCL microspheres. In animal tests, paclitaxel-loaded PCL/F68 blend microspheres showed the potent antitumor activity against hepatoma H22 cells in ascites tumor model. Conclusion The paclitaxel loaded PCL/F68 blend microspheres were found to own a faster release rate and a remarkably controlled release behavior.

Objective To evaluate the diastole asynchrony of the different segments of left ventricle(LV) and its relation with LV diastole function in the patients with hypertrophic cardiomyopathy (HCM) by quantitative tissue velocity imaging(QTVI).Methods Forteen normal controls,15 patients with non-obstructive HCM (HCM) and 12 patients with obstructive HCM (HOCM) were studied by QTVI.The regional velocity profiles of 18 segments of LV and mitral annulus of six walls along LV apical long axis view,apical two chamber view and four chamber view were obtained.The time (T_ Q-E ) from onset of QRS complexes to peak velocity during early diastole were measured.The maximal difference in T_ Q-E with in the same wall (Intra-?T_ Q-E ),the same segment (Inter-?T_ Q-E ),all 18 segments (Max-?T_ Q-E ) of LV and the mean ratio of mitral annulus early and late diastole peak velocity of six walls were calculated(Ea/Aa′).Interventricular septum basic thickness(IVSTh) and LV outflow tract gradient(LVOTPG) were measured.Results Inter-?T_ Q-E ,Intra-?T_ Q-E ,Max-?T_ Q-E were significantly prolonged and Ea/Aa′ was reduced in HCM and HOCM groups compared with control group.There was no statistically significant difference of Inter-?T_ Q-E ,Intra-?T_ Q-E ,Max-?T_ Q-E ,Ea/Aa′ between HCM and HOCM groups.In control group,HCM group,HOCM group,IVSTh and LVOTPG were increased little by little.Max-?T_ Q-E were correlated negatively with Ea/Aa′ in patients with HCM and HOCM.IVSTh and LVOTPG were mildly correlated with Ea/Aa′ in HOCM group,but not correlated with Ea/Aa′ in HCM.Conclusions Asynchrony diastole is a neccessary factor causing impairment of LV diastole function exists within the same wall and the same segment of LV in patients with HCM,but IVSTh and LVOTPG is not a neccessary factor causing impairment of LV diastole function.Asynchrony diastole in patients with HCM could be an appereance of cardiomyopathy.

Objective To evaluate the asynchrony of right ventricle(RV) and its significance in idiopathic pulmonary artery hypertension(IPAH) patients by quantitative tissue velocity imaging.Methods Twenty-five normal people,26 IPAH patients were studied.RV structure parameter(thickness of lateral wall,late diastolic and systolic area and fractional area change) and function parameter [peak systolic velocity(Sa),early diastolic velocity(Ea),late diastolic velocity of tricuspid annulus of lateral wall and Tei index] were measured and calculated.Regional velocity profiles of 6 segments of RV were obtained.The time from onset of QRS complexes to Sa and Ea(T_(Q-S),T_(Q-E)) of 6 segments were measured.The maximal difference in T_(Q-S) and T_(Q-E) in the same wall(Intra-?T_(Q-S),Intra-?T_(Q-E)),the same segment(Inter-?T_(Q-S),Inter-?T_(Q-E)) and all 6 segments(Max-?T_(Q-S),Max-?T_(Q-E)) were calculated.Results Compared with controls,Inter-?T_(Q-S),Inter-?T_(Q-E),Max-?T_(Q-S) and Max-?T_(Q-E) were significantly prolonged in IPAH patients(P(0.05)).Max-?T_(Q-S) and Max-?T_(Q-E) were correlated with structure and function parameter in IPAH patients.Conclusions Asynchrony exists in RV and have good relation with RV structure and function in IPAH patients.

Objectives To study the frequency and risk factors of osteoporosis,and the relationship between bone turnover makers and bone mineral density (BMD) in patients with ankylosing spondylitis (AS).Methods BMD in the spine and femoral neck was measured with dual-energy x-ray absorptiometry (DEXA) in 30 AS patients. Enzyme linked immunoassay was used to measure serum bone gla protein (BGP), bone-specific alkalin phosphtase (BAP), and urine deoxypyridinoline crosslinks (D Pyr).Results The patients in early stage lost the bone mass already.They had lower volume of BMD in both hip and spines than that of controls. But in the later stage,the BMD of spines was higher than that of the control group because of the calcification of the surrounding tissues of the spine.While even the BMD of femoral neck was still lower than that of normal subjects. Osteoporosis was observed in 6 patients, osteopenia in 10. Osteoporosis in AS correlated negatively with the disease duration, ESR, CRP, and X ray grades. The reduction in BMD in premenopausal women with early AS was slighter than that in men. The BMD had no significant differences in HLA B 27 (+) patients and HLA B 27 (-)patients. BGP and BAP which reflect bone formation had no differences in AS patients and controls. D Pyr which reflects bone resorption was significantly increased compared with controls.Conclusions Osteoporosis in AS is common and may be related to disease duration and severity. A significant increase in bone resorption is observed in AS with osteoporosis.

Clinical treatment shows little significance for some terminal tumor in practice,in which case hospice care seems to be particularly important.During the application of modern nursing ethics to hospice care,some aspects should be bared in mind,including trying to meet the demand of patients and their family members,showing enough respect for their right to choose,and appropriately instructing death education.Meanwhile,communication and cooperation with other medical staff should also be stressed during hospice care.

Comprehensive treatment is the hot for cervical carcinoma,but comprehensive treatment is not the superposition of several treatment methods.Surgical treatment is the main means for early cervical carcinoma and radiotherapy for locally advanced. It's sure that radiotherapy combined with hyperthermia.Abroad,concurrent chemotherapy and radiotherapy is regarded as routine treatment methods.Improvement of hyperthermia technology is more applicated in the clinical.Reducing complications after treatment and enhancing the effectiveness of the treatment of cervical carcinoma is the ultimate goal.
