In order to get information on the use of antibiotics in rural areas, 300 hospitalized patients were randomly selected from a rural hospital of Guangdong province and investigated for antibiotic use. The rate of antibiotic use in the hospitalized patients was 86.7 %; the four antibiotics at the top of the list were penicilins, cephalosporins, quinolones and macrolide. The rate of combined use of antibiotics was 68.46%. The culture of bacteria was carried out in only 4.62% of the patients and no antimicrobial susceptibility test was conducted. It is concluded that the antibiotics were not used in rational fashion in the rural hospital.

Objective To explore the carry rate and antimicrobial resistance of Staphylococcus aureus (S.aureus) among primary school students.Methods Nasal swab samples were collected from healthy primary school students in Guangzhou.Antibiotic susceptibility testing was applied to test S.aureus strains.Results The overall carriage rate of S.aureus,methicillin-resistant S.aureus (MRSA) and multi-drug-resistant S.aureus (MDRSA) among 1 012 primary school students were 40.1％,1.2％ and 4.0％,respectively.Most S.aureus isolates were resistant to penicillin,erythromycin and clindamycin.The dominant multidrug resistance patterns of MDRSA isolates were resistant to erythromycin-clindamycin-tetracycline and erythromycin-clindamycin-cefoxitin.Multifactor dimensionality reduction analysis showed that the rate of resistance to cefoxitin,tetracycline and chloromycetin among MDRSA was 104.39 times as much as that of nonMDRSA.Conclusions The carriage rate of S.aureus in healthy primary school students from Guangzhou was high and these isolates showed multidrug resistance.These data provide basis for guiding the rational use of antibiotics.

Objective To evaluate the outcome of patients with alcoholic liver disease (ALD) after orthotopic liver transplantation (OLT) and to study the prognostic factors.Methods The data of 17 patients who underwent OLT for ALD from January 2010 to March 2013 were analyzed retrospectively.The data on age,gender,history of gastrointestinal bleeding,history of splenectomy,Child-Pugh score,Maddrey' s discriminant function and MELD score were evaluated using the Kaplan-Meier method for univariate analysis.The log-rank test was applied to compare the survival rates.Results The overall survival rate at 100 weeks in patients less than 55 years old was 90％ (9/10),while that in patients more than 55 years old was 28.57％ (2/7).There was a significant difference between the two groups (P ＜ 0.05).There were no statistically significant differences between female and male patients,between patients with or without a history of gastrointestinal bleeding or splenectomy (P ＞ 0.05).There was no significant difference on survival rates after liver transplantation between patients with Child-Pugh B and Child-Pugh C,patients with Maddrey' s scores ＜ 70 and ≥70,and patients with a MELD score ＜ 30 and ≥ 30 (P ＞ 0.05).Conclusions Better survival rates were observed in ALD patients who were ＜ 55 years old after liver transplantation.The Child-Pugh score,Maddrey' s discriminant function and MELD score were of no prognostic significance.These findings still need to be verified by prospective large-scale studies.

Objective To observe the correlation of histologicalactivity(HAI) of chronic hepatitis B (CHB) with CCL20 expression, and to investigate the impact of CCL20 expression in CHB infection. Methods On the basis of established competitive quantitative RT-PCR with an internal standard, the expression of the CCL20 in the hepatocytes in different infected patterns of HBV infected cells and liver biopsies were quantified and at the same time its correlation to HAI were explored. Results In the cell levels, the expression quantity of CCL20 in control cells (HepG2), persistent HBV infected hepatocytes( HepG2. 2. 15) are (2. 65 ± 0. 02) pg/106 cells, ( 1.22± 0. 04) pg/106 cells, respectively. There were significantly differences between them ( t = 39. 66, P < 0. 01 ). The expression of CCL20 was enhanced in hepatocytes stimulated by PMA but their expression pauern was not changed. Moreover, CCL20 expression in liver biopsies with CHB was (3.54 ± 0. 65 ) pg/20 mg and CCL20 expression in control groups was ( 8. 74±0. 56) pg/20 mg. The expression of CCL20 between two groups was different (t =30. 09,P <0. 01 ) and correlation lied in between HAI and CCL20 expression in liver biopsies of CHB patients ( r = 0. 675, P =0. 023 ). Conclusion CCL20 expression was down-regulated and it was correlated to HAI of liver biopsies in CHB patients.
