Objective To explore pathogenic bacteria distribution and drug susceptibility testing results in children with purulent meningitis in Jinan area. Methods A total of 54 children with purulent meningitis were selected from January 2010 to December 2014, the cerebrospinal fluid smear and culture, according to the national standard of clinical inspection technology for bacteria isolation and identification by disc diffusion method for drug sensitive test were retrospectively analyzed. Results A total of 54 strains of pathogenic bacteria including 36 strains of gram-positive coccus, and 17 strains of gram-negative bacillus and one strain of suspected Neisseria meningitides were found. A total of 31 strains gram positive coccus is Streptococcus pneumoniae, and most gram-negative bacilli is E. coli.

Objective To investigate the clinical significance of preoperative colonoscopy for patients with benign anal diseases,and to compare the success rates of examination done by sedated colonoscopy and conventional colonoscopy.Methods The clinical data of 333 patients with benign anal disease who received preoperative colonoscopy at the Six Affiliated Hospital of Sun Yat-Sen University from April 2010 to March 2011 were retrospectively analyzed.All the patients were divided into the lesion group (120 patients) and normal group (213 patients)according to the results of colonoscopy.The measurement data and count data were analyzed using the t test and chi-square test,respectively.Results The age of patients in the lesion group was (48 ± 14) years,which was significantly older than (42 ± 14) years (t =3.75,P < 0.05).The constituent ratio of patients older than 40 years in the lesion group was 72.50% (87/120),which was significantly higher than 39.44% (84/213) in the normal group (x2=33.59,P <0.05).The proportions of male and female patients were 71.67% (86/120) and 28.33% (34/120) in the lesion group,and 62.44% (133/213) and 37.56% (80/213) in the normal group,with no significant difference between the 2 groups (x2 =2.90,P > 0.05).The benign anal diseases in the lesion group included polyp (80 cases),enteritis (30 cases),malignant tumor (7 cases),infflammatory bowel disease (7 cases),diverticulum (5 cases) and ulcer (1 case).The application rates of sedated colonoscopy in the lesion group and the normal goup were 51.67% (62/120) and 54.93% (117/213),respectively,with no significant difference between the 2 groups (x2=0.33,P >0.05).The success rate of terminal ileum intubation was 99.44% (178/179) in patients who received sedated colonoscopy,which was significantly higher than 95.45% (147/154) of patients who received conventional colonoscopy (x2 =5.61,P < 0.05).Conclusion Patients with benign anal disease might complicated with colorectal lesions,and sedated colonoscopy is recommended for preoperative diagnosis,especially for patients who are older than 40 years.

Hepatitis B virus (HBV)-induced hepatocellular carcinoma (HCC) is one of the most frequently occurring cancers. Hepadnaviral DNA integrations are considered to be essential agents which can promote the process of the hepatocarcinogenesis. More and more researches were designed to find the relationship of the two. In this study, we investigated whether HBV DNA integration occurred at sites of DNA double-strand breaks (DSBs), one of the most detrimental DNA damage. An 18-bp I-SceI homing endonuclease recognition site was introduced into the DNA of HepG2 cell line by stable DNA transfection, then cells were incubated in patients' serum with high HBV DNA copies and at the same time, DSBs were induced by transient expression of I-SceI after transfection of an I-SceI expression vector. By using nest PCR, the viral DNA was detected at the sites of the break. It appeared that integration occurred between part of HBV x gene and the I-SceI induced breaks. The results suggested that DSBs, as the DNA damages, may serve as potential targets for hepadnaviral DNA insertion and the integrants would lead to widespread host genome changes necessarily. It provided a new site to investigate the integration.

To explore a new method to identify Moutan Cortex to guarantee its safe use, internal transcribed spacer 2 (ITS2) sequence was used to identify Moutan Cortex and its adulterants. DNA was extracted and target fragments were amplified. Sequences were analyzed and assembled by CodonCode Aligner V3.7.1. Genetic distances were computed and phylogenetic tree was constructed based on kimura 2-parameter (K2P) model by MEGA 5.0. The length of the 20 ITS2 sequences of Moutan Cortex from nine different places is 227 bp, and no variation site was detected. The maximum inter-specificK2P distance of Moutan Cortex is 0, the minimum intra-specific K2P distance is 0.041, the average intra-specific K2P distance is 0.222. According to NJ analysis, Moutan Cortex from different places can get together as one branch with bootstrap support values 99%, which indicates Moutan Cortex can be easily distinguished from its adulterants. Using ITS2 sequence can accurately identify Moutan Cortex and its adulterants, it is an effective supplementary to traditional identification methods.
