Objective To study the clinical effect of ceramic cover anterior on teeth beauty.Methods 138 teeth in 34 patients with dental fluorosis were divided into two groups,the control group (69 teeth in 16 patients) was given traditional PFM cover repair,the treatment group (69 teeth in 18 patients) was given ceramic cover,they were followed up for three years.The teeth remaining rate and patient satisfaction were compared,the match color,edge fit,healthy gums,restoration integrity were compared according to the Ryge standard.Results Teeth remaining rate in treatment group was 95.7％,which was significantly higher than control group (P ＜ 0.05).The patient satisfaction was 94.4％ in treatment group and 87.5％ in the control group,the difference was significant (P ＜ 0.05).The match color,edge coloring,healthy gums and teeth sensitivity were not different between the two groups (P ＞ 0.05).The restoration integrity and marginal fit of treatment group was better than control group (P ＜ 0.05).Conclusion The clinical effect of ceramic faced in the anterior teeth beauty repair,especially in the repair of dental fluorosis is remarkable,and the remaining teeth rate higher,repair,dental restoration integrity and marginal fit is significantly better than that of resin repair,patient satisfaction is higher,the water area from non-beryl popularization and application.

Objective: To prepare modern tradional Chinese patent medicine Lemai capsules with a low dosage. Methods: Comparing the applications of seven kinds of macroporous adsorption resin in refinement of Lemai capsules' extracts in danshensu and paeoriflorin determined by HPLC as markers. Results: After refinement, the solid content of extracts decreased greatly. The content of danshensu became much lower than that before refinement The retention rate of AB 8、 X 5 and WLD for paeoriflorin is up to 80%. Conclusion: 7 kinds of macroporous adsorption resin are not proper to danshensu but some of them can be used to paeoriflorin.

TCM is unique and e ective on senile dementia in both theory and practice;therefore it is signi cant to generalize TCM understanding and experience on senile dementia for speci c therapy to reduce patients' cognition impairment and enhance their living quality.Sorting of TCM understanding on senile dementia pathogenesis and causes,it was clear that seniledementia was often seen in aging people characterized by de ciency in origin and excess in super ciality.Its de ciency in origin was de ciency of kidney essence,marrow and lucid yang failing to ascend.The origin aspect of senile dementia was believed to be the insu ciency of kidney.The de ciency of ve zang-organs was closely related to it.While the super ciality aspect was thought to be turbid phlegm and stagnant blood blocking brain and cerebral meridian with ve zang-organs all concerned.On one hand,the de ciency of kidney assisted by the de ciency of ve zang-organs could result in phlegm and blood stasis,that is to say excess resulted from de ciency.On the other hand,the stagnation of phlegm and blood stasis could block the generation,transformation and transportation of qi,blood and body uid,which would further consume the essence of the body.This is so-called de ciency transformed from excess.The above two aspects a ected each other and causing lingering pathogenic factors.

AIM: To improve the quantitive method of sarsasapogin in Kangbindu Tablet(Rhizoma Anemarrhenae, Fructus Forsythiae, etc.) METHODS: Applying HPLC-ELSD to replace TLCS. RESULTS: The new method was better than the old one in precise and repeat. CONCLUSION: The new method HPLC-ELSD is more useful.

Acute abdominal pain is a major clinical symptom of acute abdomen,and vasogenic acute abdomen caused by vascular diseases is rare and difficult to diagnose at its early stage with atypical clinical symptom and high mortality.Therefore,there is an urgent need to strengthen and improve the knowledge of surgeons about vasogenic acute abdomen.

OBJECTIVE To study the classification of the ?-lactamases produced by Citrobacter freundii.METHODS To detect the ?-lactamases produced by 33 strains of C.freundii with nitrocefin test,a multi-disk test(synergy test and antagonized test) for the inducible AmpC ?-lactamases(IABLs),AmpC ?-lactamases(ABLs) phenotype test,extended-spectrum ?-lactamases(ESBLs) screening test,and carbapenem-hydrolyzing ?-lactamases(CHBLs).RESULTS In the 33 strains,29 strains produced the ?-lactamases(87.9%);the nitrocefin tests of 27 from the 29 strains were positive(81.8%);two strains produced penicillinases,3 strains produced cephalosporinases,5 strains produced broad-spectrum ?-lactamases(BSBLs),11 strains produced ESBLs alone,and 6 strains produced ESBLs+ high-productive ABLs,the rate of ESBLs produced by the 33 strains of C.freundii was 51.5%,and 2 strains produced CHBLs(all produced ESBLs+ metallo-?-lactamase).CONCLUSIONS The rate of ?-lactamases,rate of ESBLs and co-produced rate is very high.There are six kinds of ?-lactamases produced by the 33 strains of C.freundii,mainly BSBLs and ESBLs.

OBJECTIVE To study the classification the ?-lactamases produced by Providencia spp.METHODS To detect the ?-lactamases produced by 19 strains of Providencia spp with nitrocefin test,a multi-disk test(synergy test,antagonized test for the inducible AmpC ?-lactamases(IABLs),AmpC ?-lactamases(ABLs) phenotype test and extended-spectrum ?-lactamases(ESBLs) screening test,carbapenem-hydrolyzing ?-lactamases(CHBLs).RESULTS The nitrocefin tests of all of 19 strains were positive,producing the ?-lactamases(100.0%);eight strains produced broad-spectrum ?-lactamases(BSBLs,42.1%) and ESBLs(42.1%),respectively,one strain produced overexpression of AmpC,3 strains produced CHBLs.CONCLUSIONS The rate of ?-lactamases produced by the 19 strains of Providencia spp is very high,there are three kinds of ?-lactamases,mainly BSBLs and ESBLs.

OBJECTIVE To investigate the trend of distribution and drug resistance of clinical isolates of Enterobacter cloacae during the last three years in our hospital. METHODS Strains collected from daily specimens were identified and drug resistantce with SENSITITRE bacteria analysis system. RESULTS The most strains were isolated from samples of sputum,urine,nad other excretion. The drug resistance rates to imipenem and cefepime were less than 32%. Cefoxitin,ampicillin and cefazolin were ineffective to contralE. cloacae. The drug resistance rates to penicillins,cephalosporins,chloramphenicol and aminoglycoside antibiotics increased more than 20% in last three years. CONCLUSIONS E. cloacae is multiple-resistant to antibiotics and displays higher levels of antibiotic resistance. It is suggested that antibiotics be used reasonably under the guidance of antibiotic susceptibility testing.

Objective To evaluate the quality of life and care needs of hospitalized AIDS patients and analyze the relationship between them to provide basis for clinic nurses' helping patients to improve the quality of life. Methods We adopted the general information questionnaire, patient care needs assessment questionnaire, as well as the World Health Organization Quality of life Scale (WHOQOL)and used cluster sampling method to make face to face interviews with 36 hospitalized AIDS patients. Results The care needs of the 36 AIDS patients were at a high level,all areas of quality of life were lower than the norm. The quality of life of hospitalized AIDS patients was negatively correlated with the care needs. Conclusions Clinic nursing staffs should understand and assess the care needs of patients initiatively and take appropriate measures to improve quality of life of hospitalized AIDS patients.

Objective To explore the psychological feelings of inpatients with AIDS, direct nurses to understand their psychological feelings in order to provide holistic nursing care. Methods Phenomenological method in qualitative research was adopted, 12 inpatients with AIDS were interviewed. Results The emo-tional feelings of inpatients with AIDS concerned mainly about: feeling shocked when they got to know they had affected with AIDS, wanting to commit suicide because of suffering, earnestly demanding for the com-panion of family members, the need for mental supports, planning to go on to work after feeling better be-cause of financial problems, worrying about children at home. Conclusions Nurses should estimate the changes in emotional reactions of inpatients with AIDS properly, understand their life conditions, and help them to promote their life quality by providing holistic nursing care.
