Objective To study the effect of Tibetan MedicineManu-Xitanggranules on the expression of prostaglandin E2 and TNF-a on adjuvant arthritis (AA) rats.Methods A total of 60 rats were randomly divided into the control group, the model group, the Aspirin group, the low-, medium- and high- dose Manu-Xitang granules groups (each group with 10). Complete Freund's adjuvant method was used for the adjuvant arthritis model except the control group. All the groups started treatment at 8th day, and the treatment last 20 days. The low-, middle- high-dosage groups were treated with 2.0, 1.0, 0.5g/(kg body weight) Manu-Xitang granules, while the the Aspirin group with ASP (0.27 g/kg), control and medol groups with the equal Volume saline. The body weight, the swelling of primary side of arthritis index were observed. The levels of PGE2 and TNF-α were measured by ELISA.Results At 6th, 12th, 18th day, compared with the model group, the body weights in Aspirin group, the low-, middle-, high-dosage groups significantly increased (P<0.05 or P<0.01); at the 6th day, the foot swelling (0.40% ± 0.18%, 0.50% ± 0.25%, 0.55% ± 0.35%vs. 0.85% ± 0.15%) in the Aspirin group, middle-, and high-dosage groups significantly decreased (P<0.05 or P<0.01). And the PGE2 (0.66 ± 0.31vs. 0.39 ± 0.11) and TNF-a (0.72 ± 0.24vs. 0.50 ± 0.15) in the high- dose group were significantly lower than the model group (P<0.05).Conclusions The Tibetan medicineManu-Xitanggranules could treat AA through the changes of PGE2 and TNF-a.

OBJECTIVE:To systematically review the relationship of clinical efficacy between XPD Lys751Gln (A/C),XPD Asp312Asn(G/A)and platinum-based chemotherapy in patients with advanced non-small cell lung cancer(NSCLC),and provide evidence-based reference for clinical treatment. METHODS:Retrieved from PubMed, Cochrane Library, EMBase, Medline, CJFD,VIP database and WanFang database,studies about the effects of XPD Lys751Gln and XPD Asp312Asn polymorphism on ef-fectiveness,clinical outcomes and adverse drug reaction of platinum-based chemotherapy in advanced NSCLC patients were collect-ed,and Meta-analysis was performed by using Rev Man 5.3 software. RESULTS:Totally 30 studies were included,involving 5 028 patients. Genetic testing showed that XPD Lys751Gln divided into mutant gene (Lys/Gln + Gln/ Gln) and wild-type gene (Lys/Lys),while XPD Asp312Asn divided into mutant gene (Asp/Asn + Asn/Asn) and wild-type gene (Asp/Asp). Results of Me-ta-analysis showed,the progression-free survival (PFS) of Lys/Gln+Gln/Gln patients with platinum in XPD Lys751Gln polymor-phism was obviously lower than Lys/Lys patients [OR=-1.12,95%CI(-1.73,-0.50),P<0.001],while there was no significant difference in the chemotherapy effectiveness and total survival period. The effective rate of Asp/Asn+Asn/Asn patients for platinum in XPD Asp312Asn polymorphism was lower than Asp/Asp patients [OR=0.80,95%CI(0.68,0.96),P=0.02],while there was no significant difference in the total survival period and PFS. Meanwhile,the incidence of Ⅲ-Ⅳ level gastrointestinal adverse reac-tions of Lys/Gln+Gln/Gln with platinum in XPD Lys751Gln polymorphism was higher than Lys/Lys patients [OR=0.43,95%CI (0.20,0.94),P=0.03],and there was no significant difference in Ⅲ-Ⅳ level blood system adverse reactions. CONCLUSIONS:XPD Lys751Gln polymorphism may be associated with PFS and Ⅲ-Ⅳ level gastrointestinal adverse reactions for advanced NSCLC patients with platinum-based chemotherapy,while XPD Asp312Asn polymorphism may have effect on platinum-based chemotherapy,both of them may be as estimate the chemotherapy effect and prognosis detection index of platinum-based chemo-therapy.

OBJECTIVEIn order to get the method for improving the salt resistance of Lycium ruthenium seeds and seedlings under NaCl stress, the seed germination and physiological characteristics of L. ruthenium seedlings was studied.

METHODSeveral physiological indexes of L. ruthenium seeds under NaCl stress, such as the germination rate (Gr), germination vigor (Gv), germination index (Gi), vigor index (Vi), and relative salt damage rate were measured. Other indexes of the seedlings like relative water contents (RWC) , chlorophyll contents, soluble protein contents, electrolyte leakage, the contents of malondialdehyde (MDA), and peroxidase (POD) were also measured.

RESULTNaCl at lower concentration could promote the seed germination but inhibit the seed germination at higher concentration. After the treatment by CaCl2 at the different concentrations, all germination indexes were increased. With the increase of salt concentration, the relative water contents and the contents of chlorophyll were decreased, the content of MDA and electrolyte leakage were increased. The change trend of POD activity showed the first increase and then decrease with the increase of salt concentration, which was similar to that of the soluble protein. After the treatment by CaCl2, relative water contents, chlorophyll and POD activities were decreased more slowly, and also electrolyte leakage and MDA contents increased slowly.

CONCLUSIONThe CaCl2 could significantly alleviate the damages to the seeds and seedlings of L. ruthenium under NaCl stress, and promote the salt resistance to the seeds and seedlings of L. ruthenium.

OBJECTIVEThe aim of this study was to investigate whether the three species of oral Actinomyces have inhibitory effects on the growth of oral Candida albicans in vitro.

METHODSStraight o'clock method was used to observe the bacteriostasis circle. Reverse o'clock and mixed culture method were used to study the quantitative changes of Candida albicans colony respectively.

RESULTS(1) None of the groups had been viewed the bacteriostasis circle. (2) Compared with control groups, there was a significant decrease of Candida albicans colony on Actinomyces viscosus TPY soft agar (P < 0.05). Actinomyces naeslundii and Actinomyces odontolyticus TPY soft agar were both devoid of obvious Candida albicans colony (P < 0.01). The former group (Actinomyces viscosus) and the two latter groups (Actinomyces naeslundii and Actinomyces odontolyticus) showed a striking contrast (P < 0.01). (3) Compared with control groups, a decrease of Candida albicans showed up in the mixed culture, and the difference was significant (P < 0.05). The discrepancies among the three experimental groups were of no statistical value (P > 0.05).

CONCLUSIONOral Actinomyces viscosus, Actinomyces naeslundii and Actinomyces odontolyticus could inhibit the growth of Candida albicans in vitro. However, which of them contributed more to the inhibitory effects was still not affirmed.

OBJECTIVETo investigate the antagonistic effects of three species of oral Streptococcus on the growth of oral Saccharomyces albicans in vitro.

METHODSDirect inoculation method, reverse inoculation method and mixed culture methods were respectively chosen to observe the changes of Saccharomyces albicans colony formation on the effects of Streptococcus mutans, Streptococcus sanguis and Streptococcus salivarius.

RESULTS1) No clear inhibition zone was observed in each of the groups by direct inoculation method. 2) Compared with the control groups, Saccharomyces albicans colony formation on soft agar of Streptococcus sanguis decreased significantly (P < 0.05). 3) Mixed culture method results showed that Streptococcus mutans could inhibit the growth of Saccharomyces albicans significantly at different time points (P = 0.001). 4) Under the action of bacteria culture supernatant, the count of Saccharomyces albicans in experiment groups showed statistical significance when compared with the control groups at 24, 48, 72 h (P = 0.001); The differences among the experimental groups were of no statistical significance at majority times (P > 0.05).

CONCLUSIONStreptococcus mutans, Streptococcus sanguis, and Streptococcus salivarius could obviously inhibit the growth of Saccharomyces albicans in vitro. However, it is still unclear that among which the inhibition effects is stronger. The antagonistic effects is weakened gradually.

Three-dimensional (3D) culture of cells could closely mimic the in vivo situation with regard to cell function and microenvironment compared with plane monolayer cultured cells. In this paper, we established 3D culture of rat WB-F344 cells with rotary cell culture system (RCCS) to simulate microgravity environment, and examined cells proliferation, morphology, microstructure, E-cadherin protein quantity and mRNA expression of adhesion molecules by count the number of cells, optical microscope, transmission electron microscope and reverse transcriptase-polymerase chain reaction (RT-PCR). The results demonstrated that cells were polyhedron with lots of micovilli and mitochondria, which grow well and packed together densely to form irregular aggregates. Adjacent cells were connected with desmosome and tight junction. With the regard, the aggregates behaved 3D growth characteristics. Moreover, compared with control, mRNA level of Fibronectin and E-cadherin protein were increased, the changes maybe is the part mechanism in this microgravity simulated cells culture models which strengthened cells junction. This rotating 3D model might facilitate the study of interactions of cell-cell, cell-matrix and the mechanisms.
