Objective To study clinicopathologic significance of eosinophils in human nasal polyps and the effect of corticosteroids.Methods 90 cases of nasal polyps were divided into two group randomly:corticosteriods group(n=30) with topical application of budesonide(BUD,400?g/d) for 14 days before endoscopic polypectomy,and control group(n=60) without BUD before surgery.All cases were stained with HE.Results Eosinophils showed higer in the group of nasal polyps than in the group of norm al inferior turbinate(P

Background The pathogenesis of allergic conjunctivitis has not been clearly established.Current researchers indicate that interleukin-4 (IL-4), IL-5 and IL-13 may play an important role in allergic conjunctivitis.But whether the roles of these inflammatory factors are same in different types of allergic conjunctivitis remains unclear.Objective This study was to investigate the expressions of IL-4, IL-5 and IL-13 in ocular surface with different types of allergic conjunctivitis.Methods A prospective cohort study was designed.Eighty individuals were recruited in Shanxi Eye Hospital from April 2013 to September 2014, including 20 patients with vernal keratoconjunctivitis (VKC), 20 patients with seasonal allergic conjunctivitis (SAC), 20 patients with perennial allergic conjunctivitis (PAC) and 20 normal healthy subjects.Surficial tissues were binocularly scraped using disinfected scraper from upper eyelid conjunctiva, and 4 μl of tear fluid was obtained with capillary tube.The expressions of IL-4, IL-5 and IL-13 protein and mRNA in the conjunctival epithelial cells were detected by immunohistochemistry and real-time fluorescence quantitative PCR.The IL-4, IL-5 and IL-13 concentrations in tear fluid were assayed by Luminex method.This study complied with Declaration of Helsinki and the research protocol was approved by the Shanxi Eye Hospital Ethics Committee.Written informed consent was obtained from each subject prior to entering the cohort.Results IL-4, IL-5 and IL-13 were positively expressed in cytoplasm of conjunctival epithelial cells in the VKC group,SAC group and PAC group,but the expressions of IL-4,IL-5 and IL-13 were absent in the normal control group.The relative expression levels of IL-4 mRNA were 4.11±1.24,2.71±0.71 and 2.00±0.80;the relative expression levels of IL-5 mRNA were 4.02±0.43,2.07±0.45 and 1.47±0.50;and the relative expression levels of IL-13 mRNA expression levels were 6.44±0.66,4.35±1.26 and 2.39±0.86 in the VKC group,SAC group and PAC group, showing significant differences among the 4 groups (F =51.32,220.18,162.49, all at P＜0.01).The relative expression levels of IL-4,IL-5 and IL-13 mRNA were significantly higher in the VKC group than those in the SAC group and PAC group;and those in the SAC group were significantly elevated in comparison with the PAC group (all at P＜0.05).No IL-4, IL-5 and IL-13 were detected in the tear fluid in the normal control group;while the concentrations of IL-4,IL-5 and IL-13 in the tear fluid were (14.06±3.50), (10.88±1.82) and (34.28±8.42) pg/ml in the VKC group,and (7.71 ±0.65), (5.10± 1.33), (23.77±6.29) pg/ml in the SAC group as well as (3.30± 1.50) pg/ml, (2.43± 1.28) pg/ml and (17.67 ± 4.28) pg/ml in the PAC group, showing significant differences among the 3 groups (F =200.29,260.49,128.23, all at P＜0.01).IL-4, IL-5 and IL-13 concentrations in the tear fluid were significantly higher in the VKC group than those in the SAC group and PAC group,and those in the SAC group were significantly raised in comparison with the PAC group (all at P＜0.01).Conclusions IL-4,IL-5 and IL-13 participate in the pathogenesis of multiple allergic conjunctivitis,but their expressions in the ocular surficial tissue are discriminatory in different types of allergic conjunctivitis.

After years of respiratory medicine clinical practice teaching , we have discovered that there exist some problems such as teachers' job burnout, teachers' lowprofessional knowledge level of clinical teaching and lack of teaching ability, medical students' fear, low self-esteem, psycho-logi-cal fear and emotional weariness breeding as well as the patients and their family members ' refusal of practice because of their worrying about being a test and so on. To solve these problems , we have put forward some proposals such as recognizing and rewarding teachers to affirm their teaching levels , organizing teachers to participate in academic conferences, seminars, etc. to expand their professional knowledge in order to improve their overall quality. And at the same time, we have adopted PBL teaching method, applied multimedia technology and network platforms, put emphasis on basic skills training, the improvementof departmental rotation assessment, the establishment of teaching files and doctor-patient communication and other ways to improve clinical teaching quality and develop interns' clinical thinking ability to help them transitto clinicians.

0.75).Conclusions The method of single-slice and multi-slice TSE sequence in T_2 measurement is feasible.For bone marrow and extremely long T_2 tissue(for instance,cerebrospinal fluid),however,there may be considerable discrepancy on T_2 values obtained by TSE sequence.

AIM: To investigate the refractive distribution and analysis risk factors for aircrew ametropia.
METHODS: The number of 49 cases with ametropia from 1031 aircrew during May 2013 to May 2014 were reviewed. Various types of refraction composition, age, type, position, time of flight with the subjective assessment of aircrew were analyzed and compared.
RESULTS:Of 49 cases, 43 cases (88%) were myopia, 6 cases ( 12%) were hypermetropia. , Detection rates were higher in age over 50 years aircrew and flight time more than 3000h. Detection rates were lower in self-conscious symptom heavy aircrew, fighter aircrew and good habit of using eyes.
CONCLUSION: The myopia incidence in aircrew with age >50 years and long flight time is higher, than that of fighter pilots and good habit of using eyes. We should pay attention to the increasing late-onset myopia of aviators and habit of using eyes, work intensity and time of using eyes about aircrew.

One hundred and fifty patients with 70 percent or more of carotid steno-ocelusion confirmed by digital subtraction angiography were selected to analyze risk factors for its clinical symptoms.Results of analysis showed that risk for clinical symptom increased with severity of unilateral carotid stenosis (OR = 3.546,95% CI 1.515-8.300,P = 0.004).Whereas presence of "functional complete circle of Willis" was a protective factor for it (OR = 0.208,95 % CI 0.045-0.962,P = 0.045).

OBJECTIVE To investigate the relationship of resistance and ?-lactamases of Acinetobacter baumannii.METHODS The bacteria cultured were identified with API 20NE system.The susceptibilities of the bacteria were detected by disk diffusion method.The ?-lactamases produced by these strains were characterized by three-dimensional test and 2-mercaptopropionic acid inhibition assays.RESULTS In 150 strains,the resistant rates of strains were 4.0% to cefoperazone/sulbactam.The resistant rates to imipenem,meropenem,piperacillin/tazobactam,ampicillin/sulbactam and levofloxacin were between 20.0% and 55.0%.The resistant rates to ceftazidime,cefepime,aztreonam and amikacin were above 60.0%.Three-dimensional test showed that 37 strains(24.7%) produced extended spectrum ?-lactamases(ESBLs),66 strains(44.0%)produced AmpC enzymes and 16 strains(10.7%)produced carbapenemases,in which 12 strains(8.0%) produced metallo-?-lactamases.CONCLUSIONS The resistant rates of A.baumannii to routine antibiotics are high except cefoperazone/sulbactam and carbapenem.It is the most important reason for multi-drug resistance that the strains of A.baumannii produce ESBLs,AmpC enzymes and metallo-?-lactamases.

Objective To investigate the effect of psychologic nursing on the rehabilitation for post-stroke depression(PSD) patients. Method 62 patients of 98 PSD patients were divided into 31couples. According to age, sex, course of illness and statge of illness, the patients were divided into rehabilitation nursing ( interference group) and routine nursing ( control group) with CES - D ( Center of epidemi ological survey - depression Scale ) and CNFD ( Criterion of nervous function defect). Every couple was compared with each other. Result The score of two groups before treatment was not obviously different(p＞ 0. 05). Two scores in two groups after treatment were obviously better than those of before treatment. Two scores of interference group were significantly higher compared with control group ( p ＜ 0. 05). Conclusion Interference of psychologic nursing is effective in treating post - stroke depression.
