Objective To explore the role of tumor necrosis factor (TNF-?) and endotoxin(LPS) in upper gastrointestinal bleeding in cirrhosis patients and the preventive and treatment mechanism of rhubarb. Methods 45 liver cirrhosis patients with upper gastrointestinal bleeding were treated with rhubarb, and its efficacy was compared with cemetidine's efficacy. Liver function, and serum levels of TNF-? and LPS were measured before and after the therapy. Results Patients’symptoms and liver function were improved, and serum levels of TNF-? and LPS significantly decreased after treated with rhubarb. Conclusions TNF-? and endotoxin might play an important role in upper gastrointestinal bleeding in cirrhosis patients. Rhubarb has protective and treatment effect on upper gastrointestinal bleeding in cirrhosis patients by reducing TNF-? and LPS release.

OBJECTIVE To understand flora distribution and four antifungal drugs′in vitro antifungal activity of deep fungi in nosocomial infection in order to provide help to clinics.METHODS Fungi were cultured and isolated by routine procedure which identified by VITEK microbe automatic system.Drug susceptibility test used Rosco paper disk diffusion and broth dilution method with NCCLS M27-A.RESULTS Totally 156 strains with 9 species of deep fungi that main fungi were Candida albicans,and C.tropicalis with 57.69%,and 31.41%,respectively,were isolated from nosocomial infection.The major isolating rates of clinical infection specimens were from respiratory,cardiovascular surgery,and neurological departments with 26.28%,12.18%,and 9.62%,respectively.The main infection specimens were from respiratory tract and urinary tract with 71.15% and 16.67%,respectively.Drug resistance rates to fluconazole,amphotericin B,itraconazole,and ketoconazole with Rosco paper disk diffusion were 23.08%,2.56%,12.18%,and 17.36%,MIC90 were 64.0,2.0,8.0,and 16.0mg/L,respectively.CONCLUSIONS The main deep fungi are C.albicans and C.tropicalis.Antifungal activity of amphotericin B is the highest than others.The drug resistance rate to fluconazole is more and more higher.Clinics should use antifungal drug rationally in accordance with drug susceptibility test results.

OBJECTIVE To enhance the positive rate of the blood culture in order to make pathogenic diagnosis actually and quickly and conducting usage of antimicrobial agents in clinic.To value the clinical applied circumstance of BacT/Alert 3D automated blood culture system.METHODS The 3728 blood cultures were detected by BacT/Alert 3D automated blood culture system,and bacterial susceptibility test was conducted on all isolates using Kirby-Bauer methods with CLSI standards.To statistically analyze the examined time,the positive rate and variety and drug resistance for all kinds of pathogens.RESULTS The blood culture positive rate was 6.0% in the 3728 blood cultures with 222 strains of bacteria.The false positive rate was 0.2% and the false negative rate was 0.4%.The positive rate of blood culture was 0.89% in 12 hours,2.01% in 18 hours,and 3.51% in 24 hours.Among all the 222 isolates,29.7% were Enterobacteriaceae,the drug resistant rates to amikacin,ceftazidime,ciprofloxacin,and imipenem were 13.6%,36.3%,42.4%,and 3.0%,respectively;20.3% were Staphylococcus,the drug resistant rates to erythromycin,levofloxacin,cefoxitin,and vancomycin were 75.6%,33.3%,68.9%,and 0,respectively;11.7% were Enterococcus,the drug resistant rates to errythromycin,levofloxacin,fosfomycin,and vancomycin were 96.2%,80.8%,23.1%,and 0,respectively;11.3% were non-fermented bacilli,the drug resistant rates to amikacin,ceftazidime,ciprofloxacin,and imipenem were 32.0%,52.0%,32.0%,and 32.0%,respectively;12.6% were fungi.CONCLUSIONS The pathogens in the blood specimens are more wider in distribution and more higher in drug resistance rates than before.BacT/Alert 3D automated blood culture system can be an important tool for the blood culture,it can provide the diagnostic help quickly for the clinic and increase the positive rates in blood culture.It can not only shorten the check-up time,but also be more quick and more exact.

Objective To compare the sensitivity of four kinds of drug susceptibility test method in detecting sensitivity of tigecycline against Acinetobacter baumannii.Methods The susceptibility of 72 clinically isolated strains of carbapenemase-resistant Acinetobacter baumannii(CRAB) to tigecycline in vitro was detected with disk diffusion method,VITEK 2 Compact system,E-test and MIC test strip(MTS) test strip respectively,according to FDA standards,and the differences of four kinds of drug susceptibility test methods were compared.Results The susceptibility rates of 72 strains of CRAB to tigecycline by disk diffusion method,VITEK 2 Compact system,E-test and MIC test strip were 50.00%,69.44%,36.11% and 98.61% respectively,the intermediate rates were 48.61%,29.17%,26.39% and 1.39% respectively,the resistant rates were 1.39%,1.39%,37.50% and 0.00% respectively.Compared with MTS,the classification consistency rates of E-test,disk diffusion method and VITEK 2 Compact system were 36.11%,51.39% and 70.83% respectively.Conclusion There is difference among four kinds of method for conducting the drug susceptibility testing of tigecycline against CRAB,the consistency of disk diffusion method,VITEK 2 Compact system and E-test is lower.Detecting mediation or drug resistant strains of CRAB by disk diffusion method,VITEK 2 Compact system and E-test needs to be verified by MTS or Broth dilution method.

Objective To estimate the expression of ER and PR in the endometrium of both intrauterine adhesions (IUA) and non-IUA specimens. Methods The endometrium specimens from patients undergoing hysteroscopy for confirmed moderate IUA (n=20: 10 in proliferative phase, and 10 in secretory phase) were enrolled as the IUA group in Beijing Obstetrics and Gynecology Hospital from October 2014 to August 2015. The specimens scheduled for hysteroscopy due to infertility were recruited into the control group (n=26: 13 in proliferative phase, and 13 in secretory phase). Immunohistochemistry and quantificational real-time PCR (qRT-PCR) were used to detect the expression of ER-α, ER-β and PR in endometrium with different menstrual period in both groups. Results (1) Location: in both groups, the expression of ER-α, ER-β and PR appeared in the endometrial glandular epithelial cells and the stromal cells of the endometrium. The positive brown granules of ER-α, ER-β and PR appeared mainly in cell nucleus. (2) ER-α and ER-β in the endometrium:the protein expression of ER-α and ER-β in IUA group (proliferative phase: 0.657 ± 0.028, 0.493 ± 0.023; secretory phase: 0.537 ± 0.020, 0.365 ± 0.031) were significantly higher than those of control group (proliferative phase: 0.586 ± 0.025, 0.437 ± 0.022; secretory phase:0.459 ± 0.025, 0.323 ± 0.017;all P<0.01). And the ER-αand ER-βmRNA expressions in IUA group were 2.524 ± 0.296, 1.947 ± 0.339, higher than those of control group in the proliferative phase (all P<0.01), and in the secretory phase (1.977±0.333, 1.345±0.292) were also higher than those in the control group (all P<0.01). (3) PR in the endometrium: the protein expression of PR was not significantly different between IUA group (proliferative phase:0.248±0.025, secretory phase:0.194±0.024) and control group (proliferative phase: 0.234 ± 0.019, secretory phase: 0.186 ± 0.020; P=0.162, 0.359). Meanwhile, there were no statistical differences in the mRNA expression of PR in both groups with different menstrual period (proliferative phase: 1.144 ± 0.384 versus 0.981 ± 0.306, secretory phase: 0.763 ± 0.237 versus 0.631 ± 0.203; P=0.270, 0.166). (4) ER and PR expression in menstrual cycles: the expression of ER-α, ER-β and PR in the IUA group changed with the menstrual cycles, and their expression in the proliferative phase were higher than those in the secretory phase (all P<0.05). Conclusions The expression of ER-α and ER-β in the endometrium of IUA patients changes with menstrual cycle, and are higher compared with those in normal endometrium. No difference is found in the PR expression between the two groups.

Objective To identify the gene locus and the mutation of DSRAD (double-stranded RNA adenosine deaminase) in a Chinese dyschromatosis symmetrica hereditaria(DSH) family. Methods After confirming the diagnosis of the DSH proband, the genomic DNA was extracted from the whole blood samples of every members of the pedigree. The DSRAD gene intervals were localized by linkage analysis and haplotype reconstruction. The mutation of DSRAD was detected by direct sequencing. Results The candidate gene was localized at the 1q region, consistent with the reported region. The direct sequencing results showed that there was a CAA→TAA transition at exon 2 of DSRAD in all affected family members, which consequently led to a nonsense mutation of Gln517Ter. Conclusion A nonsense mutation is found in the Chinese DSH family.
