Objective To investigate the current situation of healthcare-associated infection(HAI)in hospitals in Yunnan Province in 2015, and provide basis for formulating HAI control measures.Methods A cross-sectional survey on HAI prevalence rate , antimicrobial use,and pathogenic detection in 116 hospitals in Yunnan Province were conducted by combined methods of bed-side survey and medical record reviewing.Results A total of 64 386 hospitalized patients participated in the survey, the prevalence rate of HAI was 2.11%(n=1 357), and case prevalence rate was 2.29%(n=1 476).Difference in prevalence rates of HAI, antimicrobial usage rates, and pathogenic detection among hospitals of different beds were all significant(all P <0.01).The top 3 departments of HAI distribution were intensive care units(20.99%), burn departments(8.00%), and hematology departments (7.34%);the main infection site was lower respiratory tract(42.68%);HAI mainly caused by gram-negative bacteria(69.28%), the major were Escherichia coli , Klebsiella pneumoniae, and Pseudomonas aeruginosa.Antimicrobial usage rate at the survey day was 35.62 %, bacterial detection rate in patients receiving therapeutic antimicrobial use was 59.56%.Conclusion The cross-sectional survey on prevalence of HAI is helpful for understanding the current status of HAI, calculation of the percentile distribution of each index can promote self-evaluation for HAI-related work in each hospital.

This study investigated the tight junction (TJ) protein expression of the intestinal mucosa in a rat tail-suspension model under simulated weightlessness. Twenty-four Wistar rats were randomly divided into three groups: CON group (n=8), control; SUS-14 d group (n=8), tail-suspension for 14 days; SUS-21 d group (n=8), tail-suspension for 21 days. Occludin and Zonula Occluden-1 (ZO-1) expression levels were determined by immunohistochemical analysis and mRNA fluorescent quantitative PCR. Plasma levels of diamine oxidase (DAO) and d-lactate were determined using enzymatic spectrophotometry. Immunohistochemical results for occludin and ZO-1 showed disruption of the TJs in the intestinal mucosa in SUS-14 d and SUS-21 d groups. The expression levels of occludin and ZO-1 in SUS-21 d group were lower than those in SUS-14 d group, and significantly lower than those in CON group (Occldin: 0.86±0.02 vs 1.01±0.03 vs 1.63±0.03 and ZO-1: 0.82±0.01 vs 1.00±0.02 vs 1.55±0.01, P<0.01). Moreover, the levels of plasma DAO and d-lactate in SUS-21 d group were higher than those in SUS-14 d group, and significantly higher than those in CON group (DAO: 27.58±0.49 vs 20.74±0.49 vs 12.94±0.21 and d-lactate: 37.86±0.74 vs 28.26±1.01 vs 17.76±0.91, P<0.01). There were significant negative correlations between occludin or ZO-1 expression levels and DAO (r (2)=0.9014, r (2)=0.9355, P<0.01) or d-lactate levels (r (2)=0.8989, r (2)=0.9331, P<0.01). Occludin and Zo-1 were reduced in intestinal mucosa both in mRNA and protein levels in the rat tail-suspension model. The significant negative correlations between expression levels of TJs and plasma levels of DAO or d-lactate support the hypothesis that intestinal permeability is increased due to a decrease in TJ protein expression during tail-suspension from 14 days to 21 days.

it was 4% (3/75). GP73-positive rate in HCC was higher than that of the normal liver tissues (χ2=73.60, P<0.05). sCLU-positive rate in HCC was also higher than that of the normal liver tissues (χ2=207.94, P<0.05). GP73 expression was positively correlated with sCLU expression in HCC (r=0.405, P<0.05). GP73 and sCLU were associated with clinicopathological features including tumor differentiation, TNM stage and vascular invasion (P<0.05); GP73 and sCLU had no correlation with the patient’s gender, age, HBsAg, cirrhosis, AFP value, portal vein thrombosis and tumor numbers (P>0.05). GP73 was associated with survival but not sCLU. Conclusion:GP73 and sCLU have higher positive rates in HCC and GP73 is positively correlated with sCLU. The expression of GP73 and sCLU are probably closely related with the invasion of HCC, which can help evaluate the prognosis of the patients.

Objective To analyze the polymorphism of histidine rich protein 2(HRP II)gene in Plasmodium falciparum (Pfhrp2)from falciparum malaria patients in Yunnan Province,so as to lay the foundation for studying the defection of antigen genes of Plasmodium. Methods The filter paper blood samples and related information of falciparum malaria cases reported were obtained in Yunnan Province from August 2012 to September 2015. Under the guidance of the specific primers,the exon2 regions in Pfhrp2 gene in P. falciparum from DNA samples were amplified by PCR,and the PCR products were sequenced. The sequences of exon2 region in Pfhrp2 gene were blasted by comparing with the reference sequences AY816237,AY816240,and AY816301. Next,the polymorphism of the sequence in exon2 region of Pfhrp2 gene was analyzed by MEGA 5.04 software. The conserved sites and genetic distances between sequences were calculated by using the software as well,and the clustering tree was drawn according to the genetic distances between the amino acid sequences. Results A total of 218 bloods samples from the falciparum malaria cases in 15 prefectures of Yunnan Province were collected,and the sources of infection included Yun?nan,Africa and Myanmar. The PCR results showed that the exon2 regions in Pfhrp2 genes of 155 samples were positive by am?plification and their products were sequenced successfully. The sequence analysis showed that the length range of the amino acid residues of exon2 region in Pfhrp2 gene was from 115 aa to 298 aa,the average length was 239.7 aa. There was no statistically significance among the means of the amino acid residues of the isolates from Africa( 239.9 aa),Myanmar(239.5 aa)and Yun?nan(241.6 aa)(F=0.025,P>0.05). All the 155 amino acid sequences ended with type 12 repeat,98.1%(152/155)of them started with type 1 repeat and 1.9%(3/155)of them started with type 2. Type 2 presented most frequently repeat in all the se?quences and the average repeat times were 12.9. The homologous locus of the DNA sequences in exon2 regions of the 155 Pfhrp2 genes was 894 bp,among which the conservative sites accounted for 20.6%(186/894),and the variable sites for 78.2%(699/894). The genetic distances between the sequences of Africa isolates ranged from 0 to 0.741,and those of the Myanmar and Yun?nan isolates were 0-0.948 and 0-0.750,respectively. The cluster analysis showed that all the 155 sequences clustered into 3 cat?egories on genetic distances between amino acid sequences according to the size of the amino acid sequence length. At the same level,the sequences had approximate lengths and amino acid repeat types. Conclusion The sequence of exon2 region in Pfhrp2 gene of P. falciparum from falciparum malaria cases in Yunnan Province is highly polymorphic,the P. falciparum iso?lates are clustered mainly according to the size of the amino acid sequence of exon2 region in Pfhrp2 gene.

Objective To compare the dosimetric parameters of volumetric modulated arc therapy(VMAT),fixed field intensity modulated radiation therapy(IMRT)and three-dimensional conformal radiotherapy(3D-CRT)in the radiotherapy for the patients with locally recurrent nasopharyngeal carcinoma, and to analyze their characteristics. Methods Twelve patients with locally recurrent nasopharyngeal carcinoma were treated with VMAT, IMRT and 3D-CRT plan designed by Pinnacle 9.2 and Preciseplan 2.03 treatment planning system.The dosimetric parameters of targeted volumes and organs at risk were compared between three groups. Results The conformation indexes (CI)of VMAT and IMRT plans were similar,and they were both better than 3D-CRT plan,the difference was significant(P<0.05).The homogeneity index(HI)in three groups were similar,there were no statistically significant differences between them(P>0.05).The monitor units(MU)and beam time in 3D-CRT group were better than those in other two groups,and VMRT group was better than IMRT group,the statistical differences were observed between three groups (P<0.05 ).There were no statistical differences of organs at risk such as brainstem and lens between three groups(P>0.05).The doses of the spinal cord,optic nerve,optic chiasm and temporal lobe of brain in VMAT and IMRT groups were better than those in 3D-CRT group,there were statistical differences between them(P<0.05),and the data in VMAT and IMRT groups were similar,and there were no statistical differences(P>0.05).Conclusion There are differences of the targeted dose distribution between the three kinds of radiation technology, while VMAT and IMRT plans can cover the targeted areas and reduce the received doses of organs at risk.The CI,MU and beam time of VMAT plan are better than those of IMRT plan. 3D-CRT plan only has advantage in the MU and beam time.
