Nonalcoholic fatty liver disease (NAFLD) is a common liver disease with multiple factors involved,and its incidence is gradually increasing around the world.Recent studies have found that gut microbiota is involved in the development and progression of NAFLD.This article summarizes the association between gut microbiota and NAFLD from the aspects of influencing factors for gut microbiota and the roles of gut microbiota and its metabolites in the development and progression of NAFLD and points out that the intervention of gut microbiota and its metabolites may be a new target for the prevention and treatment of NAFLD.

Objective:To observe different effects of moxibustion at Zusanli (ST 36) and Yanglingquan (GB 34) on electrogastrogram (EGG) of patients with functional dyspepsia (FD). Methods:A total of 65 cases were randomized into a Zusanli (ST 36) group (n=33) and a Yanglingquan (GB 34) group (n=32) by random serial number, to receive moxibustion therapy to the corresponding point respectively. The 8-lead EGG was used before and after treatment to collect EGG parameter of the gastric body, antrum of stomach, lesser curvature and greater curvature, including the dominant frequency, slow wave percentage, average frequency, response area and motility index. Results:After treatment, the dominant frequency and slow wave percentage were improved in nearly the whole stomach area in Zusanli (ST 36) group, showing statistical significances (bothP<0.05); the slow wave percentage and average frequency were improved in stomach body and antrum of stomach in Yanglingquan (GB 34) group, showing statistical significances (bothP<0.05); moxibustion at Zusanli (ST 36) had a significantly higher influence on EGG than Yanglingquan (GB 34) , in which the lifting of slow wave percentage was significantly higher than Yanglingquan (GB 34) group (P<0.05). Conclusion: Moxibustion at Zusanli (ST 36) and Yanglingquan (GB 34) has the effect of adjusting abnormal EGG pattern in FD patients. Compared with Yanglingquan (GB 34), Zusanli (ST 36) has a superior effect in improving EGG in stomach area.

AIM: To analyze the pathogens and drug sensitivity of chronic dacryocystitis in order to provide evidence for clinical drug use.
METHODS:Lacrimal secretion of 171 cases with chronic dacryocystitis was sampled for pathogenic bacteria culture identification and drug sensitivity test. Based on the results, the isolation rate of pathogens strains, the pathogens kind of chronic dacryoeystitis, main pathogens of chronic dacryocystitis, and sensitive drug for pathogens were analyzed.
RESULTS: The isolation rate of pathogens strains was 76. 61% ( 131 cases ). The pathogens constituting the chronic dacryocystitis were predominantly gram-positive coccus,the percentage was 72. 52% (95 cases), among which staphylococcus hominis occupied 27. 48% ( 36 cases), staphylococcus epidermidis 16. 79% (22 cases), streptococcus viridans 12. 98% (17 cases). The majority of these bacteria were sensitive to cefoperazone-sulbactam, tobramycin, gentamicin and levofloxacin. For gram -positive coccus, cefoperazone - sulbactam, gentamicin and tobramycin were the most sensitive drug. For gram-negative bacilli, cefoperazone - sulbactam, tobramycin and levofloxacin were most sensitive drug.
CONCLUSION: Staphylococcus hominis is the main pathogen of chronic dacryocystitis, tobramycin can be used as the first choice for local treatment of chronic dacryocystitis.

AIM: To establish a standard for quality control of Xinfang Biyan Capsule(Radix Saponikovae, Radix Angelicae Dahuricae, Radix Scutellariae, etc.). METHODS: TLC and HPLC were used. RESULTS: Flos Magnoliae, Radix Saponikovae, Flos Chrysanthemi, Radix Bupleuri in the capsule could be identified by TLC, and baicalin content in the capsule could be measured by RP-HPLC with a linear relatioship at a range of 0.243 ?g- 2.43 ?g(r= 0.999 8 ). The average recovery was 98.15% and RSD was 0.15% . CONCLUSION: The methods are accurate and can be used for the quality control of Xinfang Biyan Capsules.

Background and purpose:Ovarian cancer is associated with a high recurrence and mortality due to the existence of cancer stem cells. The purpose of this study was to investigate the effect of casticin (CAS) on the capability of self-renewal in ovarian cancer stem cell like cells (OCSLCs) derived from SKOV3 cell line. Methods:SKOV3 cell line cells were cultured in vitro, and OCSLCs were obtained and amplified through suspended culture with conditioned medium of the stem cells. The phosphorylation level of FoxO3a was analyzed using Western blot. The protein expression of FoxO3a was inhibited by FoxO3a speciifc siRNA transfection, and then the ratio of sphere-formation was detected. Results: Compared with parental cells, OCSLCs over-expressed phosphorylated FoxO3a (pFoxO3a) and had elevated ratio of sphere-formation [(3.1±0.3)% vs (34.8±6.8)%, P<0.05]. CAS significantly inhibited the capability of sphere-formation in OCSLCs and down-regulated the expression level of pFoxO3a. And the transfection of FoxO3a speciifc siRNA suppressed the protein expression of FoxO3a and attenuated the inhibitory effect of CAS on the sphere-formation of OCSLCs. Conclusion: Reduced expression level of pFoxO3a is involved in the effect that CAS inhibits sphere-formation of OCSLCs derived from SKOV3 cell line.

Objectives To investigate the prevalance of quinolone resistance in Laribacter hongkongensis and to evaluate the influence of agar dilution and disc diffusion methods on susceptibility testing for the bacterium. Methods Susceptibility to quinolones of L.hongkongensis was tested by agar dilution and disc diffusion methods. The results for both methods were compared. Results L.hongkongensis isolates exhibited different susceptibility rate for quinolones (levofloxacin>ciprofloxacin>norfloxacin>nalidixic acid). All of the fish isolates were susceptible to levofloxacin and more than 90%were susceptible to ciprofloxacin and Norfloxacin. However,by agar dilution, only 62.50%, 37.50%,48.21%, 19.64%of the frogs isolates were susceptible to levofloxacin, norfloxacin, ciprofloxacin, nalidixic acid, respectively. For fish isolates, comparision of susceptibilities between agar dilution and disc diffusion showed a high (> 95%) percentage agreement for levofloxacin and ciprofloxacin and the highest crepancies were observed with norfloxacin (100%) .But it showed a high discrepancy when comparing the two methods for frogs isolates. Conclusions The resistance rate of L. hongkongens to quinolones was high , especially for frog isolates. The results suggested the use of agar dilution on susceptibility testing for quinolones in L. hongkongensis.

Objective To explore whether Forkhead O transcription factor-3a (FoxO3a) activity affects the capability of sphere-formation of ovarian cancer SKOV3 cell line.Methods Sphere-forming cells (SFCs) were obtained and amplified through suspended culture with conditioned medium of the stem cells in SKOV3 cell line.After SKOV3 cells were transfected with FoxO3a specific siRNA,the protein expressions of FoxO3a and Bmi1 and the ratio of sphere-formation were compared with Western blot and sphere-forming assay,respectively.Results Compared to parental cells,SFCs from SKOV3 cell line had higher ratio of sphere-formation and over-expressed Bmi1 and pFoxO3a.Transfection of FoxO3a specific siRNA down-regulated the protein expression of FoxO3a and upregulated expression of Bmi1 in SKOV3 cells,and enhanced the capability of sphere-formation.Conclusions Silence of FoxO3a leads to enhanced capability of sphere-formation in SKOV3 cell line.
