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.

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.

OBJECTIVE: To evaluate the sustained efficacy of 2-year sublingual immunotherapy (SLIT) and 1 year after 2-year SLIT in children with allergic rhinitis (AR). METHOD: This study is a randomized, open and prospective trial. One hundred twenty children (between 4 and 11 years old) suffering from AR duo to mite were chosen from November, 2008 to June, 2009 in department of otolaryngology in our hospital divided into two groups: 60 underwent 2-year course of SLIT and one year follow-up combined with 3-year drug therapy as SLIT group; 60 received only drug therapy as control group. The patients were evaluated at three time points (baseline, end of SLIT and 1 year after SLIT discontinuation) regarding symptom scores including total nasal symptom score (TNSS), sneezing, rhinorrhoea, nasal obstruction, nasal itching and total medication scores (TMS) and adverse reaction. RESULT: (1) At the end of SLIT, the symptom scores excepting sneezing and total medication scores in SLIT group are obviously lower than those in control group (P < 0.01). At 1 year after SLIT discontinuation, all of the score including sneezing (P < 0.05) in SLIT group are lower than those of control group. (2) At the end of SLIT and 1 year after SLIT discontinuation, all of the scores are lower than those at baseline in SLIT group (P < 0.01); the scores were no different in SLIT group between the end of SLIT and 1 year after SLIT discontinuation (P > 0.05). But at the end of SLIT and 1 year after SLIT discontinuation, TMS was higher than it at baseline in control group (P < 0.01). At 1 year after SLIT discontinuation, nasal obstruction score was higher than it at baseline (P < 0.05). CONCLUSION SLIT can obviously improve the AR and the efficacy can sustain after 1-year SLIT discontinua tion. Drug increased in 3 years without SLIT.

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.

Objective To explore the clinical effect of different scheme of moxifloxacin and levofloxacin for elderly multi drug resistant pulmonary tuberculosis.Methods 136 cases of elderly patients included in the study were randomly divided into the observation group 1 and observation group 2 with 68 cases in each group according to the sequence in group.The observation group 1 used moxifloxacin regimen for treatment of pulmonary tuberculosis while the observation group 2 used levofloxacin regimen.The two groups were treated for 18 months and observed the clinical curative effect,and the sputum negative,pulmonary lesions absorption,empty changes and adverse reactions.Results The total efficiency of the observation group 1 was 92.6％,which in the observation group 2 was 72.1％,the total efficiency of the two groups had a significant difference (x2 =9.917,P =0.002) ;the sputum negative conversion rate of the observation group 1 at the end of 3 months was significantly higher than that of the observation group 2 (x2 =4.115,P =0.043),no significant difference was found at the other time points (all P ＞ 0.05) ; after treatment,the obvious absorption + absorption of lung lesion in the observation group 1 was 59 cases,accounting for 86.8％,that in observation group 2 was 48 cases,accounting for 70.6％,two groups of lung lesions absorption had significant difference (x2 =5.303,P =0.021) ; the pulmonary cavity closure + reduced in the observation group 1 was 52 cases,accounting for 76.4％,that in the observation group 2 was 41 cases,accounting for 60.3％,with significant difference between the two groups (x2 =4.115,P =0.043) ;there was no significant difference in adverse reaction of the two groups (P ＞ 0.05).Conclusion Moxifloxacin anti tuberculosis regimen has a better curative effect in treatment of elderly patients with multi drug resistant pulmonary tuberculosis,which should be expanded the application.

Purpose To investigate the MRI findings and to improve the understanding of spinal epidural angiolipomas. Materials and Methods MRI findings were retrospectively analyzed in two cases of surgery and pathology proven spinal epidural angiolipomas. Relevant literatures were reviewed. Results Two cases of spinal epidural angiolipomas were located in the lumber and lower thoracic spinal canal. The tumors were elongated or spindle in shape within the epidural space, and parallel to the longitudinal axis. In both cases part of the tumors were hyperintense on T1WI and T2WI, attenuated on fat-saturated sequences with mild enhancement. Some areas were hypointenseon T1WI, hyperintenseon T2WI, unattenuated on fat-saturated sequences with apparent enhancement. Angiolipomas were classified according to the MRI features. One was type I and the other was type III. Both cases were non-infiltrative. Conclusion MRI shows the size, shape, MRI signals and the association with the adjacent structure of spinal epidural angiolipomas. The MRI classification is helpful for improving the understanding of the tumor. MRI is the best imaging modality to diagnose spinal epidural angiolipomas.

Objective To investigate the roles of interleuldn (IL)-17,IL-10,and matrix metalloproteinase12 (MMP-12) in the pathogenesis of atherosclerosis and further to understand the intervention mechanism of atorvastatin for atherosclerosis.Methods Eighteen Japanese white rabbits were randomly divided into 3 groups:control,model and intervention groups (n =6 in each group).The control group,model group and intervention group were fed basic diet,high-fat diet,and high-fat diet plus atorvastatin (5 mg/(kg·d),respectively for 12 weeks.The levels of serum total cholesterol (TC) and triglyceride (TG) were determined by enzymatic colorimetric method; the levels of low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were determined by selective precipitation method; the levels of IL-17,IL-10,and MMP-12 were measured by double antibody sandwich enzyme-linked immunosorbent assay (ELISA); the pathological morphology changes of atherosclerotic plaque was observe by HE staining; and the thickness of the intima,intima/media ratio,plaque area,and plaque proportion were calculated by image analysis software.Results The expression levels of serum TC,TG,LDL-C,and IL-17,as well as those of IL-17 and MMP-12 of the intervention group were significantly lower than those of the model group (all P ＜0.05),but they were still higher than the control group (all P ＜0.05),while there was no significant difference in the level of HDL-C.The level of serum IL-10 of the intervention group was higher than that of the model group and the control group (all P＜0.05).The thickness of intima,intima/media ratio,plaque area,and plaque proportion of the intervention group were all significantly lower than those of the model group (all P ＜0.05).Correlation analysis showed that the plaque proportion was significantly positively correlated with IL-17 (r =0.847,P =0.001) and MMP-12 (r =0.839,P =0.001),and was negatively correlated with IL-10 (r =0.794,P =0.002); IL-17 was significantly positively correlated with MMP-12 (r =0.709,P=0.001),and was significantly negatively correlated with IL-10 (r =0.738,P＜0.001).MMP-12 was significantly negatively correlated with IL-10 (r =0.563,P =0.015).Conclusion The increased levels of IL-17 and MMP-12,as well as the decreased level of IL-10 illustrate that inflammatory factors play an important pathological role in the pathogenesis of atherosclerosis.In addition to lipid-lowering effect,atorvastatin may decrease the degree of chronic arterial inflammatory response and play a role in anti-atherosclerosis by decreasing the expression of IL-17 and MMP-12,as well as increasing the expression of IL-10.

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
