Objective To understand the epidemiological characteristics of imported malaria in Luoyang City,so as to pro-vide the evidence for malaria prevention and control in this city. Methods The Epidemic situation data from network reports, as well as the case survey and the epidemiological investigation data of imported malaria were collected and analyzed in Luoyang City from 2010 to 2013. Results A total of 98 imported malaria cases were reported in Luoyang City from 2010 to 2013,includ-ing 35 cases of vivax malaria,57 cases of falciparum malaria,4 cases of ovale malaria and 2 cases of quartan malaria. All the cases were confirmed by laboratory detection. Seventy-one cases(72.44%)returned from African countries,and 27(27.55%) cases returned from Southeast Asian countries. The majority cases were young man,and 78.57%of the cases were diagnosed by different levels of centers for disease control and prevention. There was no significant seasonal variation in onset time. The medi-an time from onset to seeing doctor was 6 days. Conclusions The epidemic situation of imported malaria is quite serious in Luoyang City. It is necessary to further strengthen the professional training and multi-sectoral cooperation ,and take effective pre-vention and control measures to reduce the hazard of imported malaria.

Objective To discuss the pathological classification and lesion's inner imaging features of lung adenocarcinoma presented as pure ground-glass opacity.Methods CT imaging features of 156 pGGO lesions which confirmed by surgery and pathology were analyzed in retrospectively.There were 58 lesions of pre-invasive (including atypical adenomatous hyperplasia and adenocarcinoma in situ),32 lesions of minimally invasive adenocarcinoma and 66 lesions of invasive adenocarcinoma.CT features were analyzed including lesion density,vacuole sign,air bronchogram and abnormal vascular changes (vascular dilatation,distortion or rigid).Results There were statistical difference in lesions density and abnormal vascular changes in 3 different pathological types (P ＜ 0.05),with increase of lesions invasive,the incidence of uneven density and abnormal vascular changes increase,its mean the more invasive of the lesion,the lesion tent to be more uneven and higher incidence of the dilation,twist or rigid of the vascular happened;while the incidence of the air bronchogram will be higher when the lesions invasive degree increased,but there was statistical difference only between the pre-invasive and invasive groups (including minimally invasive adenocarcinoma and invasive adenocarcinoma) (x2 =4.868,P =0.027).Conclusions The uneven density and abnormal vascular changes had certain value in differential diagnosis of lung adenocarcinoma presented as pGGO.

Objective To evaluate the efficacy and safety of combination therapy with domestic bezafibrate and fluvastatin in patients with combined hyperlipidemia. Methods 180 patients with combined hyperlipidemia were randomly divided into two groups. They were assigned to receive 40 mg fluvastatin (n = 90) or a combination of 400 mg bezafibrate and 40 mg fluvastatin (n = 90) for 24 weeks. Results After 24 weeks treatments, the serum TC, LDL-C levels were reduced (P <0.01) and HDL-C level was increased more significantly (P <0.05) in the combi-nation therapy group. Conclusion Combination therapy with bezafibrate (400 mg) and fluvastatin (40 rag) is more effective than fluvastatin(40 mg) monotherapy.

Objective To analyze the correlation between clinical compliance and peritoneal dialysis treatment outcome and quality of life on end-stage renal disease patients with high and low clinical compliance.Methods Total of 137 continuous ambulatory peritoneal dialysis (CAPD) patients of end-stage renal disease were collected in second-class hospital in Weifang by convenience sampling,and divided into high and low clinical compliance group (68 patients in each)according to ESA score.SF-36,dropout rate,fatality rate,infection rate and rehospitalization rate were used to estimated,and Cox multi-factor regression model was used to analyze correlation between therapy outcome and risk factors.Results 61 CAPD patients (44.52％) were dropout,with 23 cases (37.70％) by death.The dropout rate without death(11.8％,44.12％),fatality rate (7.4％,26.5％) and infection rate(8.8％,38.2％)had significant difference between high and low clinical compliance group (P＜0.05).The SF-36 scores of 8 dimension also had significant difference between the two groups.Cox multi-factor regression model showed that clinical compliance was an important risk factor of therapy outcome and death(HR =1.68,P＜0.05).Conclusion Clinical compliance is an important risk factor of therapy outcome,and should be listed as efficacy monitoring index of peritoneal dialysis and the target of improving the curative effect of the intervention.

Objective To investigate the diffevential diagnostic value of preinvasive and invasive lung adenocarcinoma (including minimally invasive adenocarcinoma and invasive adenocarcinoma) presented as pure ground-glass nodules(pGGN) by CT.Methods One hundred and fifty-six cases of pGGN verified by operative pathology were retrospectively analyzed,including 58 ca ses of preinvasive adenocarcinoma and 98 cases of invasive adenocarcinoma(TNM staging were T1N0M0).The CT features and sex were statistically processed.The difference between the CT features and sex were performed by thex2 test.The ROC curve of lesion focus size was drawn.Results Statistically significant differences were found in the lesion shape,vacuole sign,air bronchogram,blood vessel through,tumor-lung interface and vascular cluster sign between the two groups(all P＜0.05).The ROC curve showed that the accuracy rate of invasive adenocarcinoma was 75.0％ when the size of the pGGN lesions was larger than 15.35 mm.Conclusion The lesion size,shape,vacuole sign,air bronchogram,blood vessels through and vascular cluster sign have some predictive value.

ABSTRACT:Objective To explore the role of HIF‐1αin the pathogenesis of hepatopulmonary syndrome (HPS) and its relationship with GRP78 .Methods The HPS model in rats was induced by multiple pathogenic factor .The samples were assessed by using Western blotting analysis for HIF‐lα, GRP78 and VEGF164 . The expressions of VEGFR‐2 and CD105 were observed by using immunohistochemical staining .Results The protein level of HIF‐1αwas significantly increased in HPS group at week 8 compared with that at week 4 and 6 groups and corresponding normal control groups .With the development of HPS ,protein level of GRP78 was gradually increased at each time point significantly and reached the highest level at week 8 ;protein level of VEGF164 showed a similar change with GRP78 ,but the peak was at week 6 .Immunohistochemical results showed that the protein expressions of VEGFR‐2 and CD105 were gradually increased in lung tissue as HPS progressed .The protein level of GRP78 was positively correlated with HIF‐1α,VEGF164 ,VEGFR‐2 and CD105 ,respectively (P<0 .05) .Conclusion HIF‐1αis most likely together with GRP78 to play a critical role in promoting pulmonary microvascular remodeling in the pathogenesis of HPS in rats .

Objective To study the relationship between the expression of Mycobacterium tuberculosis small heat shock protein Hsp16.3 and the apoptosis of infected mouse alveolar macrophages.Methods The laboratory mice were infected with bacterial suspension of the international standard virulent strain of Mycobacterium tuberculosis H37Rv strains (H37Rv),Hsp16.3 gene deletion mutants of the international standard virulent of Mycobacterium tuberculosis H37Rv strains(△H37Rv),or sterile saline solution (normal control)by the tail vein. After successful replication of mouse infection model in each group,we cleaved the alveolus of each group of mice and collected lavage fluid to obtain alveolar macrophages of the infected mice at days 1 ,3 ,5 ,7 ,9 ,1 1 ,1 3 and 1 5 .Then the infection status of macrophages was observed with confocal laser scanning microscopy;flow cytometry was used to detect the apoptosis rate of alveolar macrophages of the infected mice;Caspase-3 and Bcl-2 expressions were examined by Western blot.Results The apoptosis rate of Hsp16.3 gene was higher in deletion strain (△H37Rv)group and H37Rv strains (H37Rv)group than in control group.The apoptosis rate of alveolar macrophages in △ H37Rv group gradually increased,peaked at day 7 ,and then gradually decreased.It was significantly higher in H3 7 Rv group than in H3 7 Rv strain group from day 1 to 7 and from day 1 3 to 1 5 (P<0 .0 5 ).Caspase-3 and Bcl-2 protein expressions in the macrophages of△H37Rv group and H37Rv group were higher than those of control group.Caspase-3 expression in the microphages of △H3 7 Rv group and H3 7 Rv group gradually increased from day 1 to 7 and peaked at day 7;it peaked again at day 13 in H37Rv group.However,Caspase-3 expression remained significantly higher in△H37Rv group than in H3 7 Rv group (P<0 .0 5 ).Bcl-2 expression in △H3 7 Rv group did not change much at the early stage of infection (P<0 .0 5 ),but gradually increased after day 9 .Bcl-2 expression in H3 7 Rv group did did not change much from day 1 to 7 (P<0.05),but gradually increased after day 7.However,it remained lower in△H37Rv group than in H37Rv group,especially after 7 days(P<0.05).Conclusion Mycobacterium tuberculosis small heat shock protein Hsp16.3 can inhibit the apoptosis of macrophages during the early and late stages of infection,and this inhibition may be achieved by inhibiting the expression of apoptotic protease Caspase-3 and promoting the expression of Bcl-2 protein.

OBJECTIVETo seek effective drugs inhibiting herpes simplex virus (HSV-2) with the signal pathway required by virus replication as the target spot.

METHODHSV-2-induced Vero cytopathic effect was observed, and MTT method was adopted to detect call activity, in order to assess the antiviral capacity of freeze dried powder of aqueous extracts of Saururus chinensis (AESC). Western blot was used to check the effect of AESC on signal pathway induced by HSV-2 virus in HeLa cells.

RESULTAESC obviously inhibits the pathway activation of CPE induced by HSV-2 infection and NF-kappaB required for virus replication. The inhibition ratio of AESC freeze dried powder at 0.10, 0.03, 0.01 and 0.003 g x L(-1) were (70.68 +/- 3.39)%, (61.74 +/- 2.13)%, (39.31 +/- 1.10)% and (18.54 +/- 3.44)%, respectively. The IC50 was determined at (0.023 +/- 0.004) g x L(-1). The inhibition concentration of the positive control acyclovir was 0.001 g x L(-1) (5.0 x 10(-6) mol x L(-1)). The best administration time was from 2 h before infection to 6 h after infection. Western blot also showed that AESC can notably inhibit HSV-2-induced NF-kappaB nuclear transfer.

CONCLUSIONAESC can inhibit HSV-2 virus replication, which is related to the pathway activation of NF-kappaB required for virus replication.

Objective To study the effect of transitional care program involving group activities on self-efficacy in patients with cervical cancer. Methods A total of 34 cases from October 2013 to March 2014 in our hospital diagnosed with cervical cancer in parallel comprehensive treatment were selected as the observation group patients, and 34 cases from January to June in 2013 in our hospital diagnosed with cervical cancer in parallel comprehensive treatment were selected as control group. The control group was given routine nursing, while the observation group was given the transitional care program involving group activities. The general self-efficacy table ( GSES) and the EORTC QLQ-C30 were compared between the two groups. Results The scores of self-efficacy before intervention were (30. 41 ± 5. 54) in the observation group and (30. 22 ± 6. 14) in the control group, which had no significant difference (t =0. 241,P >0. 05). The scores of self-efficacy after intervention were (46. 24 ± 5. 33) in the observation group, which was significantly higher than (33. 35 ± 8. 45) in the control group (t=14. 145,P<0. 01). There were no significant differences in the physical function, role function and shortness of breath between the two groups ( t = -0. 985, -1. 314, 0. 238, respectively;P >0. 05). The rest 12 domain of the observation group were significantly better than those in the control group (t=3. 957, -8. 747, -7. 654, 4. 215, 14. 864, 4. 156, -39. 169, 3. 759, 2. 996, 2. 878, 3. 344, 14. 621, respectively;P<0. 05). Conclusions The transitional care program involving group activities can improve the self-efficacy of cervical cancer patients, enhance patients self-management level and the ability to adhere to health behaviors, and improve the quality of life of the patients.
