Objective To discuss with micro-tympanoplastic operation with osteo retention on treating cholesteatomatous otitismedis. Methods Choose 33 cases cholesteatomatous otitis medis patients who toke the tympanoplastic with osteo retention operation,then analyze the postulate and method of the operation, curative effect and complication after operation. Results Follow up with those patients by 12-72 months, and when 3-4 months after operation we endoscopiced the ears, could see that 43 cases of patients ear mastoid process and tympanic sinus were covered with epithelium, those mastoid cavity were well epithelial metaplasia;and the middle ear was separate from mastoid cavity; 39 cases patient of transplant eardrums are heal up (39/43, 90.7%). 2 cases have perforation of the tympanic membrane toke place after 4 months and 6 months with the operation, and it will heal up by anti-inflammatory drug and laser burning, 1 case had tympanic sinus hyperplasia with granulation tissue, and also had grassery juice; after taken anti-inflammatory drug and change bandage for 15 weeks, the symptom disappear. 1 case had grassery juice of operation cavity, after taking anti-inflammatory drug and physiotherapy, the symptom disappear in 24 weeks. After operation the pure tone audiometry shows that air conduction raise (16.8±6.8) dB HL, hearing raise up to:79.1%(34/43). Conclusion Base on right indication of operation choose, taken combined therapy of ambi-operation period, focus of infection are thoroughly cleaning up. Tympanoplastic with osteo retention are treating well with patients of cholesteatomatous otitismedis.

Gallstone ileus is a rare and potentially serious complication of cholelithiasis.Its clinical symptoms are nonspecific.From March 2005 to September 2012,19 patients with gallstone ileus confirmed by surgery or endoscopy were admitted to the Pudong New Area People's Hospital.The accuracies of X-ray,uhrasonography,CT and magnetic resonance imaging (MRI) were 0/10,0/5,19/19 and 9/9,respectively.CT examination might be the first choice for diagnosing gallstone ileus ; the classical computed tomography (CT) presentation of gallstone ileus was the Rigler triad,including pneumobilia,ectopic stone and mechanical ileus; MRI examination was superior to CT examination in exposing the fistula,and can provide abundant information,which is important for designing the surgical procedures and judging the prognosis; X-ray and ultrasonography are beneficial in screening the diseases.

Objective:To determine bacteriostatic abilities ofArtemisia argyi extracts,and to explore the effect ofArtemisia argyi extracts on oral ulcer in rats.Methods:We extracted the mixture ofArtemisia argyi volatile oils and water-extraction by leaching method and evaluated the anti-microbial effect ofArtemisia argyi extracts on common oral floras in vitro.The rat cheeks were burnt by NaOH to establish the models of oral ulcer.The curative effects of crude drug of Artemisia argyi extracts at 2.0,1.0,0.5 g/mL on oral ulcer in rats were evaluated by measuring the oral ulcer healing time.Serum TNF-α level and expression of proliferating cell nuclear antigen (PCNA) were analyzed by ELASA and immunohistochemical staining.Results:Artemisia argyi extracts obviously inhibited the Staphylococcus aureus and Streptococcus.NaOH-made oral ulcer in rats were successfully established.The crude drug at 2.0 and 1.0 g/mL obviously reduced healing time,significantly inhibited the release of TNF-α,and improved the PCNA level in the ulcer tissues (All P＜0.01).The extracts obviously reduced the local inflammatory reaction and promoted tissue repair of oral ulcer.Conclusion:Artemisia argyi extracts promote tissue repair of oral ulcer via inhibiting bacterial growth,reducing the release of TNF-α and improving the PCNA level.

Objective To analyze the protein in hemolymph from adult female Anopheles stephensi (An. Stepheni) infected by Plasmodium yoelii after feeding with sucrose solution containing nitroquine or simple sucrose solution with two dimensional gel electrophoresis technique. Methods Hemolymphs from nitroquine fed, infected blood fed, and sucrose solution fed adult female An. stephensi were collected using the expulsion method on the third day after the feeding. Hemolymph protein concentration was examined with Bradford method. Then the hemolymph protein was analyzed by two dimensional electrophoresis. The protein spots were visualized by Coomassie brilliant blue staining. The spots were scanned and automatically analyzed by the ImageMaster VDS CL (Amersham Pharmacia) and ImageMaster 2D Elite software (Amersham Pharmacia). Results The protein concentration in the nitroquine fed group was always lower than that in the infected blood fed and sucrose solution fed groups. Two dimensional gel electrophoresis revealed 101 protein spots in nitroquine fed and 115 protein spots in the control with 51 matched, but unmatched 50 and 64 protein spots were detected in the treatment group and the control group, respectively. Different protein spots were mainly located at the molecular weight of (40-60)?10 3 and at the isoelectric points of basic end. Conclusion Two dimensional gel electrophoresis may directly reflect the difference of the protein. Both the difference of protein concentration and the protein spots may be involved in nitroquine induced melanotic encapsulation of Plasmodium yoelii oocysts.

For optimal adaptive cultivation region selection, we used ecology factors characterized Duolun region as model area to carry out the adaptive habitat division of Paeonia lactiflora. Similar priority comparison of ecology factors.in 91 cities were calculated by Fuzzy methods, then, distance of the ecology factors were transferred to spacial model by geography information system (,GIS) and modified by soil utilization map of China. The results showed that P. lactiflora were mainly distributed in the Daxing'an Mountain, Changbaishan and qinling range which were divided into six grades of suitable regions belonging to three geographical distributed units. The most similar areas to Duolun were Huade, Xilinhaote, Suolun and Zhangbei. P. lactiflora's distribution and quality are relevant with longitude and latitude, and temperature and rainfall.

Objective:To investigate the prevalence of hearing loss among community-dwelling older people aged 60 and over, and also to compare the discrepancies between self-reported hearing loss and hearing loss diagnosed via audiometry.Methods:Subjects were from the Prevention and Intervention on Neurodegenerative Disease for the Elderly in China(PINDEC)project.By using the stratified multi-stage cluster random sampling method, a total of 10 347 residents aged 60 years and over were selected from 12 counties and districts in Liaoning, Henan and Guangdong Provinces and hearing function assessment was performed in 2020 through otoscopy, pure-tone audiometry and questionnaires.Hearing loss(HL)was defined by the World Health Organization criteria.Self-reported hearing loss was assessed by asking participants whether they had difficulty in hearing.The χ2 and Cochran-Armitage trend tests were used to analyze the differences in HL between different groups.The multivariate Logistic regression model was applied to assess factors influencing HL. Results:In 2020, the prevalence of HL among the elderly aged 60 and older in Liaoning, Henan and Guangdong Provinces was 69.8%(95% CI: 68.9%-70.7%). The prevalence of HL in men was higher than that in women, and increased gradually with age.The prevalence of mild HL was 47.2%, and the prevalence of moderate, severe and profound HL were 18.0%, 3.6% and 0.9%, respectively.Multivariate Logistic regression analysis showed that factors positively correlated with HL were aging, male sex, living in rural areas and working in manual labor.Education level was negatively correlated with HL.Of the 7223 participants who were found to have HL, 5106(70.7%)self-reported having good hearing.Those of a younger age, with a higher educational achievement, having a spouse, or with mild HL were more likely to report having good hearing(all P<0.05). Conclusions:Hearing loss is quite prevalent among community-dwelling older people, and there is a large discrepancy in prevalence between self-reported HL and HL diagnosed via audiometry.Screening and comprehensive intervention for hearing loss for the elderly should be strengthened.
