Objective To profile the types of bacteria in bile culture and study their antibiotic sensitivity pattern in patients with varying de-grees of acute cholangitis and to provide data guidance for the prevention and treatment of bacterial infection.Methods The clinical data of 230 patients with acute cholangitis who were admitted to our hospital from April 2010 to April 2014 were retrospectively analyzed.Classifica-tion of pathogenic bacteria and the antibiotic sensitivity test in bile cultures were performed using VITEK 2 Compact Biomerieux microbiologi-cal system.Results Within the 230 patients,172 tested positive for biliary bacteria,and the positive rate was 74.78%(172/230).There were 237 strains of pathogenic bacteria,including 135 strains of Gram-positive bacteria (56.96%),comprised mainly of Enterococcus and Staphylococcus aureus,96 strains of Gram-negative bacteria (40.5 1%),comprised mainly of Pseudomonas aeruginosa,Escherichia coli, and Klebsiella pneumonia,and 6 strains of fungi (2.53%),comprised mainly of yeast.Significant difference in the positive rate of bacteria was detected between patients with mild and severe cholangitis (χ2 =4.58,P =0.028).Gram-negative bacteria were the predominant i-solates in patients with mild and moderate acute cholangitis,while multiple bacterial infection was more common in patients with severe cholangitis.Biliary bacteria had a higher rate of susceptibility to vancomycin,imipenem,and amikacin compared with other antibiotics. Conclusion Gram-positive bacteria are the predominant pathogens in acute cholangitis.Early detection,immediate intervention,and ac-curate drug susceptibility test should be implemented at regular intervals to direct effective clinical therapy.

BACKGROUND: Human embryonic stem cells (hESCs) are pluripotent cells which may differentiate into tissues of all three germ layers. Such research as the feeder-free growth of hESCs is few in China. Fibroblast growth factor (FGF) is a major factor to maintain the undifferentiated state of hESCs.OBJECTIVE: To evaluate the ability of FGF at different concentrations in maintaining the undifferentiated state and pluripotency of hESC lines in the long-term culture.METHODS: Two cell lines of hES-8 and hES-18 were cultured with mouse embryonic fibroblast condition medium for 3 passages and then transferred into mouse embryonic fibroblast condition medium containing different concentrations of FGF: 100, 160, 250 μg/L for 8 passages. The hESCs were removed from the petri dish, cell clusters were digested with collagenase IV and gathered. Cell differentiation and pluripotency were observed. The eighth generation of the hESCs were collected and incubated into severe combined immunodeficiency mice, so as to observe teratoma formation. Morphologies of the cells were evaluated. Alkaline phosphatase staining, surface labeling immunocytochemical analysis and RT-PCR assay method were utilized to determine the OCT-4 expression and tumorigenesis in vivo.RESULTS AND CONCLUSION: Cultured in mouse embryonic fibroblast condition medium containing 160 and 250 μg/L FGF, two cell lines of hESC could maintain undifferentiated state: Clones were round with a high ratio of nucleus to cytoplasm. Large areas in the center of clones were undifferentiated cells, while surrounding the clones were differentiated cells; Strong positive expression for alkaline phosphatase staining was observed; Two cell lines showed high levels of OCT-4 transcription factor protein; The surface markers SSEA-4, TRA-1-60, TRA-1-81 were all positive on both two lines; The hESC clusters could form embryoid body in vivo 10 days later; 3 germ layers of teratomas were also obtained after implanted into severe combined immunodeficiency mice. Mouse embryonic fibroblast condition medium containing 100 μg/L FGF was not sufficient to maintain the long-term proliferation of hESCs, and most of the cells differentiated and died after 4 passages. Alone with concentration 160 μg/LbFGF or more could maintain two hESC lines undifferentiated stably in vitro, has no influence on the differentiation and totipotency of two cell lines.

In the patients with end-stage renal disease (ESRD) with hepatitis B virus (HBV) infection who underwent hemodialysis, the viral load of HBV DNA is relatively low and stable.For this phenomenon, some studies suggest that hemodialysis can reduce the HBV DNA load.The mechanism, which remains unclear, may be as follows: when HBV DNA enters the dialysate through the dialysis membrane, it was adsorbed onto the dialysis membrane;some virus particles were destroyed, and antiviral substances were produced in the course of hemodialysis.At present, there is no consensus on the mechanism responsible for the influence of maintained hemodialysis on the viral load of HBV DNA.This article reviews the factors involved in the influence of maintained hemodialysis on the viral load in ESRD patients with HBV infection and the recent progress.

Abstrcat:Pulmonary artery hypertension ( PAH) is a cardiopul-monary disease with extensive obliterative changes in the small to midsized pulmonary arterioles. This review summarizes the al-tered inflammation and immune processes underlying the devel-opment of PAH, and discusses inflammatory factors, immune cells, Rho kinase and gene implicated in PAH. Preclinical stud-ies have provided the basis for abnormal immune response in ani-mal models of the PAH, and this paper, based on inflammatory/immune response mechanisms, proposes PAH potential therapeu-tic targets.

BACKGROUND: In many parts of the body, muscle diastolic and contractive activities can promote the body's energy metabolism. Furthermore, the muscles also play an irreplaceable role in maintaining body posture and joint stability. OBJECTIVE: To summarize the rules of muscle function and aging changes, to search for research related to the trainability of old muscle function, and to provide references for muscular anti-aging research in field of sports medicine. METHODS: Taking senescence, aging, muscle function, exercise, training in English as the search terms, Pubmed database from January 2000 to May 2009 was retrieved; Taking aging, muscle function, training in Chinese as the search terms, CNKI database from January 2000 to May 2009 was searched. Literatures were limited to English and Chinese languages. Inclusive criteria: research closely related to the trainability of motor function and muscle metabolic function in the elderly; Exclusive criteria: obsolete and lack of credibility of the literature. RESULTS AND CONCLUSION: Totally 67 literatures were screened out by computer, according to inclusion and exclusion criteria, 31 documents of which were involved in the analysis. Based on the recent research On muscle function, the muscle function can be summarized into three aspects: motor function, metabolic function and maintenance function. The elderly muscle aging is mainly showed in these 3 aspects. How to reconstruct these functions through resistance training? The concerning data were summarized in this paper, to verify the trainability of ageing's muscle motor and metabolism functions, but no study indicates that the maintenance function can be reconstructed, and deserves further studies of sports science.

Objective To evaluate the genotoxicity of europium nitrate to the Vicia faba L root-tip cells. Methods The primary roots of Vicia faba L were cultured for 6 hours in the solution of Eu series(64,32,16,8,4,2,1 ?g/ml) at 25℃.And then the roots were repair-cultured in double distilled water for 24 h. The root tips of Vicia faba L were dissected and fixed,stained and the micronucleus rate,mitotic index and the rate of chromosomal aberrations were determined. Results From 1 ?g/ml to 32 ?g/ml,the rate of micronucleus increased with the increasing of the europium nitrate dosage(D),presented a dosage-effect relationship(r=0.949). From 2 ?g/ml to 64 ?g/ml,mitotic index decreased with the increasing of the europium nitrate dosage,presented a dosage-effect relationship(r=-0.852). From 1 ?g/ml to 64 ?g/ml,chromosome fragments(CF) and frequency of chromosomal aberrations(FCA) increased with the increasing of the europium nitrate dosage with a dosage-effect relationship significantly(rD-CF=0.915,rD-FCA=0.872). Conclusion Europium nitrate has the certain genetic toxicity to the Vicia faba L root-tip cells. The chromosome fragments may be one of the reasons to produce micronucleus.

Objective To investigate the clinical and characteristic imaging findings of intracranial gliosarcoma. Methods The imaging findings of surgery and pathology proved intracranial gliosarcoma in 15 cases were retrospectively analyzed. There were 10 males and 5 females, ranging in age from 44 to 67 years (mean age 58 years). Results All tumors were located in supratentorium, including 13 cases in the temporal or parietal lobe, 1 cases in the occipital lobe, and 1 cases in the thalamus. Tumors appeared as round or ellipse in shape. The lesions ranged in size from 3 to 9 cm (mean 4.6 cm). CT scan showed mingled hypo and isodensity in 7, hypodense in 4 with CT value from 18 to 22 HU, hyperdense in 4 with the CT value from 48 to 55 HU. Enhancement appeared as an irregular pattern. The margin was clear. Most intracranial gliosarcoma showed perifocal edema. MRI were examined in 6 cases, whichappeared as low signal on T 1WI, and as high signal on T 2WI. There was irregular enhancement of the mass. Conclusion It was difficult to make the correct preoperative diagnosis for gliosarcoma, but it was possible to make a tendency diagnosis using CT or MR combined with the history. Contrast enhanced CT and MRI should be useful in differentiating gliosarcoma from glioblastoma.

Objective To analyze the handling measure in period of ambo-operation and postoperative care of patients with abdominal surgery in advanced age over 80 years. Methods A retrospective analysis of 102 integrity data of patients with abdominal surgery in advanced age over 80 years was done. Results 100 patients recovery and discharged. The incidence of postoperative complications was 55.9% (55/102). Postoperative death was oberserved in two patients. Conclusion In patients over 80 years old,handling measure in period of ambo-operation is very impor-tant. Degeneration of organ function and more comorbidities made operation more dangerous. A well preoperative prep-aration and postoperative care, an intensive treatment of comorbiditius, the prevention of apoplexia and reducing the chance of emergency operation, will make operation more effective.
