Objective: To determine the inhibitory effects of maltitol-gum on Streptococcus mutans, Lactobacilli and Actinomyces viscosus in dental plaque. Methods: Thirty 13-15 years old children with DMFS>4 were divided into three groups, maltitol chewing gums group(A group), xylitol chewing gum group(B group) and blank gum base group (C group). The plaque samples were collected and colony forming units were counted. Results: The levels of three-species cariogenic pathogens in three groups were statistically down-regulated when compared with the baseline(P<0.001).Moreover, A group and B group resulted in a higher decrease of Streptococcus mutans levels compare with C group(P<0.05). The levels of Lactobacilli and Actinomyces viscosus were not statistically different between groups(P>0.05). Conclusion: Maltitol-gum can lead to a significant suppression on Streptococcus mutans levels in dental plaque,while the inhibitory effect of the maltitol-gum on Lactobacilli, Actinomyces viscosus is not obvious.

Objective To observe the protective effect of Erigeron Breviscapus(Vant.)Hand-Mazz(EBHM) on retinal ganglion cells(RGCs) and optic nerve in rabbits with elevated intraocular pressure(IOP). Methods Twenty rabbits with chronic elevated IOP were divided into two groups randomly: EBHM treated group(the ocular hypertension with EBHM treated subgroup and the normal IOP with EBHM treated subgroup) and untreated group(the simple ocular hypertension subgroup and the simple normal IOP subgroup). EBHM was irrigated into the stomachs to the treated group after IOP elevated continuously for 7 d.For light and electron microscopy studies,the rabbits' eyes were made into eyeball samples and optic nerve samples after 60 d.The density of RGCs,thickness of retinal nerve fiber layer(RNFL),and optic nerve axons were observed and quantitated by computer image analysis system.The ultra-microstructure changes of RGCs and optic nerve axons were observed by electron microscope.Results(①The RNFL) thickness,RGCs density and number of axons of the two ocular hypertension subgroups were decreased,compared with those of the two normal IOP subgroups(P

Tricholoma giganteum is a famous species product of Jishou in the wes t of Hunan.It have not only special biological characteristics such as formatio n and ecological enviromment,but also delicious,fragrant with abundant nutrien t.It's mycelium can be isolated and growing well in medium,but its fruiting bo dy is difficult to be formed.

This paper introduces a data warehouse model for outpatient payments, which is designed according to the requirements of the hospital financial management while dimensional modeling technique is combined with the analysis on the requirements. This data warehouse model can not only improve the accuracy of financial management requirements, but also greatly increase the efficiency and quality of the hospital management.

Objective: To investigate the killing activity of cytokine-induced killer (CIK) cells after incubation with autologous tumor cell lysate-pulsed dendritic cells (Ag-DC) and to evaluate the immune functions of patients, the clinical efficacy and side effect of Ag-DC in combination with CIK on hepatocellular carcinoma. Methods: Peripheral blood mononuclear cells were isolated from 24 patients with hepatocellular carcinoma, and cultured with granulocyte-macrophage colony-stimulating factor and interleukin-4 to produce dendritic cells (DCs). The DCs were pulsed with autologous tumor cell lysate. T lymphocytes from PBMC were cultured with interferon-Y (IFN-γ), IL-2, CD3-moAb, and IL-1α to prepare CIK. The killing effect of CIK on SMMC-7721 was investigated after CIK was incubated with Ag-DC. After immunotherapy with Ag-DC and CIK, immunolog-ic and clinical responses of the 24 patients were evaluated. Results: The killing effect of CIK was remarkably improved after CIK was incubated with Ag-DC. The immunotherapy with DC and CIK alleviated symptoms and improved the immune functions of the patients. Except for transient fever and chill, no remarkable adverse events were observed. Conclusion: Ag-DC in combination with CIK shows short-term efficacy on hepatocellular carcinoma through inducing specific anti-tumor immunity and can be an effective adjuvant therapy for hepatocellular carcinoma.

Condition optimization for immobilization of Fungal laccase with Nylon Net and glutaraldehyde and the nature of the immobilized enzyme were studied. The optimum conditions of the immobilization are: Nylon Net is crosslinked with 5% glutaraldehyde 15mL for 6 hours; the 30U laccase is added for immobilization for 8 hours. On this case, the recovery of enzyme activity was 50.3%. Compared with free enzyme, the thermal stability of immobilized enzyme was improved evidently but the optimal pH decreased slightly. 52% enzyme activity of immobilized laccase was hold after 8 cycles treatment with low concentration pulp wastewater.

The thermostability of the inulinase was studied in this resea rc h. Some alcoholic materials and thickening agent could enhance the thermostabli lity of the inulinase. Using glycerol、xanthic pastern and though orthogonal ex periments of three elements and three levels, a satisfying protective agent, whi ch included glycerin(6%), xanthan gum(0.6%) and CaCl_2 (100mmol/mL) and ha d a significant effect on the enhancement of the inulinase thermostability, was acquired.

One hundred Pseudomonas aeruginosa quorum-sensing-related genes were selected and their primers were synthesized. The fragments of specific sequences which are related QS genes were amplified by PCR. These verified sequences were inserted into the vector pMD-18T for sequencing. These DNA fragments were dotted onto glass slides to make cDNA microarray. Hybridization was performed with cy3/cy5-dCTP labeled probes. The scanning data of early stationary phase and mid-logarithmic phase indicated that 9 genes were up-regulated and 6 genes were down-regulated. Undergoing the different medicines,we took tobramycin as an example to compare the expression diversity. The results confirm that the QS cDNA chip is useful,and may contribute to better understand the mechanism of quorum-sensing,and can help us find the new targets for restraining the growth of Pseudomonas aeruginosa.

Objective To measure the levels of cross-reactive neutralizing antibodies responding to various subtypes of HIV-1 strains in people with HIV-1 infection in Chongqing and to analyze their character-istics.Methods Two hundred and thirty-six plasma samples were collected from patients with chronic HIV-1 infection in Chongqing city.The single-round-infection assay in TZM-bl cells were performed to screen the plasma samples with cross-reactive neutralizing antibodies against various subtypes of HIV-1 strains by using HIV-1 pseudovirus strains and to measure the 50%inhibitory dose ( ID50 ) .Results Eight-een out of 236 (7.63%) plasma samples were able to neutralize various B subtypes and/or C subtypes of HIV-1 pseudovirus strains, among which 15 plasma samples showed the great ability to neutralize pseudovir-us strains of different subtypes.Conclusion The cross-reactive neutralizing antibodies against various sub-types of HIV-1 strains existed in plasma samples collected from people with chronic HIV-1 infection in Chongqing city.

ObjectiveTo compare the efficacy and safety of intermittent patient-initiated single-dose antibiotic prophylaxis and continuous antibiotic prophylaxis for the prevention of recurrent urinary tract infection (UTI) in postmenopausal women. MethodsA randomized controlled clinical trial was conducted for the prevention of recurrent urinary tract infection. Single dose of antibiotic was given every night in continuous antibiotic prophylaxis group and every time after exposure to conditions predisposed to UTI in intermittent antibiotic prophylaxis group. The duration of prevention was 12 months in both groups. ResultsThe effective rates of intermittent antibiotic prophylaxis and continuous antibiotic prophylaxis were 71.0% and 81.8% respectively (P＞0.05). The incidence of gastrointestinal adverse reaction in intermittent antibiotic prophylaxis group was significantly lower than that in continuous antibiotic prophylaxis group (7.7% vs 28.6%,P＜0.05). ConclusionsCompared with continuous antibiotic prophylaxis, intermittent patient-initiated single-dose antibiotic prophylaxis is a better prophylaxis with less gastrointestinal adverse reactions for the prevention of recurrent urinary tract infection in postmenopausal women.
