Objective To study the clinical significance of C-reactive protein(CRP),neutrophil granulocyte ratio(N% ) in acute exacerbations of hospitalized patients with chronic obstructive pulmonary disease ( COPD ). Methods The serum CRP levels,the gross of N% were detected of the same 71 patients with acute exacerbations of COPD before treatment and after getting better. And the correlations among above-mentioned indexes,the days counter before getting better and the days counter during hospitalization were observed. Results (1) The levels of CRP and N% of patients after getting better were significantly lower than those before treatment(P ＜0. 01). (2) There was a significant correlation between N% and the days counter before getting better(r =0.240,P ＜0.05) and also a significant correlation between the days counter before getting better and the days counter during hospitalization (r = 0. 567, P ＜0.01). Conclusion The serum CRP level and N% were objective markers in estimating pulmonary infection in COPD patients with acute exacerbations. And N% was a reliable indicator of judging the days counter before getting better and better than CRP.

Objective To explore the effect of nursing intervention on rehabilitation of stroke patients with hemiplegia.Methods 60 cases of hemiplegic patients after stroke were divided into the control group and the experimental group with 30 cases in each group randomly.The rehabilitation status was evaluated and compared using self rating depression scale (SDS) and activities of daily living (ADL) scale before and after intervention.Results After nursing intervention,ADL score and SDS score were better,treatment effect was also better,but SDS total score showed no significant difference.Conclusions Nursing intervention can effectively reduce or eliminate depression of patients after stroke,strengthen subjective initiative of patients,so that patients can actively cooperate with the treatment,and promote disease rehabilitation.

Based on the questionnaires completed by 985 medical students,this article finds out that female students value more on the factors of health care and development when choosing a job,while male students are more confident in selecting goals and making career plans.Students from different family backgrounds have great difference when facing the elements such as reputation,social status and selfevaluation.Students from different majors take quite different opinions to health care,self evaluation,career information and career planning.There is little difference among different grades of medical students.Vocational values correlate positively with career decision-making self-efficacy.

The concentration of plasma eadotoxin and serum C-reactive protein(CRP) were measured in 48 cases with leukemia.Plasma endotoxin was apparently higher in 9 cases with gram-negative bacterial infection than those with other organisms infection.The serum CRP concentration was strongly positive in patients with leukemia complicated by bacterial infection.It is suggested that measurement of plasma endotoxin and serum CRP would aid the diagnosis of G- bacterial infection in patients with leukemia

With the quick development revelant techniques, proteomics is a very active subject in modern biological fields. The key techniques of proteomics are two dimensional electrophoresis, mass spectrometry and bioinformatics. From the new point of view, proteomics may play a vital role in the early detection of neoplasm by looking for tumor specific protein and elucidating the relationship between the change of expression and different phases of tumorigenesis. The article briefly review the relevant technique, strategy and application for the early diagnosis of in digestive system tumors.

Objective To explore the clinical behavior,pathological and immunohistochemical characteristics and diagnosis, treatment methods of gastrointestinal stromal sarcomas (GISS). Methods Retrospective analysis was perfomed over 36 GISS patients based on clinical data and pathological data. Results GISS occurred more in the stomach and small intestine, than colon and rectum. Immunohistochemical staining showed CD117, CD34 expression,the positive rates were 91.7% and 86. 1%. Conclusion GISS is a rare malignant tumor, GISS diagnosis depends on the histologic and immunohistochemical test. CD34 and CD117 in the positive diagnosis has its special significance. Surgery is the main treatment.

Objective To compare the effectiveness of two-suppression therapy with over-plus hyperopia lens and atropine mydriasis for school-age chihtren with monocular amblyopia. Method One hundred and sixty-seven cases of children with monocular amblyopia in the age of 7-12 years old were observed, who were randomly divided into two groups, using over-plus hyperopia lens or atropine mydriasis to suppress the normal eye, and the amblyopia eye was comprehensive trained, followed-up of 3 years. Results The effect rate was similar between over-plus hyperopia lens and atropine mydriasis [90.7%(78/86) and 91.4%(74/81), respectively]. There was no significant difference (P>0.05). Conclusions For school-age children with monocular amblyopia, you can use over-plus hyperopia lens inhibit the normal eye sight, its effect is similar with the atropine mydriasis.

Objective:To investigate procalcitonin and C-reactive protein levels in diarrheal patients who underwent irinotecan che-motherapy. Methods:Procalcitonin and C-reactive protein were detected among 85 diarrheal and 63 non-diarrheal patients after irinote-can chemotherapy. Results:According to WHO classification, patients without diarrhea are classified as grade 0, whereas patients with diarrhea can be classified as gradesⅠ-Ⅳ. In grades 0,Ⅰ,Ⅱ,Ⅲ, andⅣpatients, the levels of procalcitonin were 0.29 ± 0.17, 0.30 ± 0.18, 0.36 ± 0.20, 1.24 ± 0.22, and 2.15 ± 0.26 ng/mL on the second day, respectively. However, on the fourth day, the procalcitonin lev-els were 0.28 ± 0.15, 0.30 ± 0.14, 0.34 ± 0.18, 2.00 ± 0.22, and 2.40 ± 0.28 ng/mL, respectively. Moreover, in grades 0,Ⅰ,Ⅱ,Ⅲ, andⅣ, the levels of C-reactive protein were 6.06 ± 1.85, 6.12 ± 1.16, 6.20 ± 1.68, 22.62 ± 4.55, and 31.26 ± 5.23 mg/L on the second day, respectively. On the fourth day, the C-reactive protein levels were 5.80 ± 1.82, 5.94 ± 1.14, 6.15 ± 1.55, 30.52 ± 4.74, and 38.67 ± 5.68 mg/L, respectively. No significant difference was found between the procalcitonin and C-reactive protein levels of stagesⅠandⅡpa-tients (P>0.05), but a significant difference was found between stagesⅠ, andⅡpatients and stagesⅢandⅣpatients (P<0.05). Con-clusion: Monitoring levels of procalcitonin and C-reactive protein may be helpful in the early evaluation of the severity of diarrhea. This process has prognostic effect and can be used to assess whether patients have enterogenous bacterial infection. Monitoring the lev-els of these proteins has certain clinical value and can be used to guide early anti-infection therapy.
