ABSTRACT
Objective:To introduce a modified stent technique of nasal septal extension graft (SEG) with auricle cartilage, and to explore its effect on rhinoplasty.Methods:For 116 patients that underwent rhinoplasty, the cartilage of bilateral auricula was sutured with shell alignment and the dovetail was modified to prepare SEG stent; PTFE or silicone prosthesis was used for nasal dorsal graft. The patients were follow up for 6-18 months after surgery. A number of indicators including length of nose, tip projection, nasal tip and nasolabial angle morphology were used to assess surgical outcomes.Results:The 116 patients obtained satisfactory appearance immediately after operation. Length of nasal extension was 3-6 mm, tip projection was extended by 2-5 mm. Following up for 6-18 months showed stable effect (0.5-1.5 mm retraction) and satisfactory nose tip and nasolabial angle. The skin color was normal. No deformity occured in the ear cartilage donor area existed with no obvious scar.Conclusions:The modified SEG stent of auricle cartilage has good support and stability. It has a good effect on the slight and moderate extension of the short nose. In addition, the elevation of the nasal tip and the severe short nose of the first rhinoplasty and secondary rhinoplasty with mild contracture are also improved.
ABSTRACT
Objective This epidemiologic survey aims to investigate the changes in prevalence and risk factors for non-alcoholic fatty liver disease (NAFLD)in the elderly people who are living within Pudong San-lin region.Methods We retrospectively analyzed annual physical check-up data in 2012 and 2014 for elderly people living in this region (aged≥70years).Demographic variables including age,sex,blood pressure,body mass index (BMI)were recorded.Serum fasting glucose level was determined and liver and kidney function were assessed.Abdominal echo-Doppler examination was performed.NAFLD was diagnosed according to Chinese guideline on management of NAFLD (revised version).Results Among 2127 sub-jects with physical check-up in 2012,the occurrence rate of NAFLD was 27.46% (23.02% and 31.02%for men and women,respectively).Type 2 diabetes was detected in 224 subjects and 33.93% of them de-veloped NAFLD (26.73% and 39.84% for males and females,respectively).Among 1771 subjects who received physical check-up in 2014,the occurrence rate of NAFLD increased up to 32.29%,with NAFLD rate being 29.97% and 34.19% for men and women,respectively.In 185 subjects with type 2 diabetes, 49.19% developed NAFLD (47.56% and 50.49% for men and women,respectively).Thus,compared with the findings during physical check-up in 2012,the occurrence rate of NAFLD was significantly in-creased during physical check-up in 2014 for both male and female subjects of overall and diabetic popula-tions (P <0.05 for all comparisons).Further analysis showed that for 185 diabetic patients who had phys-ical check-up in 2014,systolic and diastolic blood pressures,BMI,and serum levels of fasting glucose lev-el,alanine aminotransferase,aspartate aminotransferase,total cholesterol,and triglyceride were significant-ly higher in patients with NAFLD than in those without NAFLD (all P <0.05).Multivariate regression a-nalysis revealed that BMI,total cholesterol and triglyceride levels were independent risk factors for occur-rence of NAFLD in diabetic patients.Conclusions This epidemiologic survey demonstrates a significant increase in the occurrence rate of NAFLD for the elderly people (especially with type 2 diabetes).Hyper-lipidemia,obesity,and hypertension are major risk factors for NAFLD in diabetic patients.
ABSTRACT
OBJECTIVE To study drug resistance and distribution of infectious bacteria in lower respiratory tract among inpatients and outpatients and use the experience for reference of clinical application.METHODS Bacterial culture of the qualified sputum sample of patients who were admitted from Jan to Dec 2005 was done.The bacteria identification and drug sensitivity tests were done by ATB system.RESULTS Totally 687 strains of bacteria were isolated,the dominant were Gram-negative bacilli(81.5%).Among them,the Pseudomonas aeruginosa was 21.3%,the Acinetobacter baumannii was 19.8%,the Klebsiella pneumoniae was 14.3%,the Stenotrophomonas maltophilia was 16.6%,the Escherichia coli was 7.5%,and the others were 17.5%.The second pathogens were fungi(15.9%).The Gram-positive bacteria were the lowest ones.The results of drug sensitivity tests indicated,the imipenem was the most sensitive for Gram-negative bacilli except the P.aeruginosa and the M.stenotrophomonas(99.1% to 100.0%).For the P.aeruginosa,the amikacin was the highest one,and for the S.maltophilia,the highest was sulfamethoxazole-trimethoprim.CONCLUSIONS The dominant pathogenic bacteria in lower respiratory tract in our area are Gram-negative bacteria.For the same antimicrobial agent,different bacteria have a different sensitivity.We should select the antibiotic according to the results of drug sensitivity test.
