Through analyzing medical personnel's duty under Bio-psycho-social Medical Mode, this paper states that medical personnel's duty should be emphasized not only on preventing and curing diseases, but also on solving patients' psychological problems.Therefore it states that death education, first, to medical professionals themselves,second,to the patients and their family,is very important,at last it also inquires into the mode of death education.

Objective To study the clinical efficacy and effects on CRP levels of ambroxol in treatment of pulmonary infections.Methods 68 patients with pulmonary infection were selected and divided into the observation group(n =34)and control group by using the random number table method(n =34).The observation group was treated with ammonia bromine atomization inhalation treatment,while the control group was treated with alpha chymo-trypsin atomization inhalation therapy.The clinical effect and duration of symptoms and signs disappeared of the two groups were compared,and serum CRP level changes in the two groups before and after treatment were also compared. Results After treatment,the clinical total effective rate was 91.2% of the observation group.And the total effective rate was 70.6% in control group,the comparison between the two groups had statistically significant difference (χ2 =4.316,P <0.05).Compared with the control group,the observation group patients symptoms disappear time(3.1 ± 0.5)d,pulmonary symptoms disappear time(4.1 ±1.7)d,body temperature returned to normal time(4.1 ±1.6)d and hospital stay(8.4 ±2.8)d were significantly shortened,the differences were statistically significant (t =2.879, 2.918,3.025,3.972,all P <0.05 ).The serum CRP levels in patients of the observation group was (22.45 ± 9.27)mg/L,which of the control group was (33.45 ±14.67 )mg/L,both were significantly lower than before treatment,the difference was statistically significant (t =6.314,5.126,all P <0.05).The lower degree of serum CRP level in the observation group was obviously better than tha in the control group,the difference was statistically significant (t =6.263,P <0.05).Conclusion The ambroxol can achieve significant clinical effect on treatment of pulmonary infections,which can significantly shorten the patientˊs symptoms and lung signs disappear time and length of hospital stay,etc.It can reduce the serum CRP level,and is worth popularization and application in clinic.

Objective To observe the effect of selenium on the ACTH positive cells in the pars distalis of pituitary of rat with colon mucosa cancer induced by azoxymethane(AOM).Methods Twenty 3 weeks old Sprague Dawley male rats were randomly divided into 4 groups: the normal control group;the experimental control group;the selenium before AOM induced colon mucosa cancer group;the selenium after AOM induced colon mucosa cancer group.To induce rat colon mucosa cancer,3 weeks old SD male rats received(i.p.) injections of AOM at a dose of 15mg/kg once a week for two weeks.Selenium(Na_2SeO_3,4mg/L) began to be provided in the drinking water before and after AOM administration,and lasted for the whole experiment period.The rat pituitary tissues were excised from the 34 weeks old rats.The morphological changes of the ACTH positive cells in the pars distalis of pituitary were observed using immunohistochemical methods,and then the results were analyzed by image analysis system.Results Aberrant crypt foci(ACF) and aberrant crypt(AC) were showed in the colon mucosa of rats that received two weekly i.p.injections of AOM by light microscopy with methylene blue staining.The ACTH positive cells in the experimental group rat displayed a significant increase compared with those in the normal control group rat(P

Objective Through detecting the expression of erbB-2 and erbB-3 of epithelial growth factor receptor family in clinical specimens of salivary adenoid cystic carcinoma, to explore the role of erbB-2 and erbB-3 in the carcinogenesis and development of salivary adenoid cystic carcinoma. Methods Thirty-four specimens of adenoid cystic carcinoma were tested with immunohistochemical assay. Then the relationship between the expressions of erbB-2, erbB-3 and the gender, age of patients, TNM staging, tumor size and nerve invasion were analyzed.Results The positive expression ratios of erbB-2 and erbB-3 were 64. 7% and 32.4% respectively. And 29.4% of tumors were positively stained both by erbB-2 and erbB-3. The expression of erbB-3 was significantly correlated with TNM staging of tumors (P = 0. 026). The correlationship between the expressions of erbB-2 and erbB-3 was also found. Conclusions erbB-3 and erbB-2 may play important roles in the carcinogenesis and development of salivary adenoid cystic carcinoma. The positive expression of erbB-3 was associated with the biological behavior of tumors and prognosis of patients, and might become one of markers to evaluate the prognosis of patients.
