Objective:To investigate the prevalence of volatile sulfur compounds ( VSC ) in oral cavity of preschool children, and to analyze related factors, thus to provide scientific basis for the prediction and treatment of halitosis. Methods:The VSC content ( hydrogen sulfide, methyl mercaptan, dimethyl sul-fide) of 170 preschool children (4 to 6 years old) was detected by a portable gas chromatograph Oral-ChromaTM . The status of the oral health was evaluated. The living habits and other aspects were obtained through questionnaires from the children' s parents. A soft package for social statistics version 13. 0 ( SPSS 13 . 0 ) was used in which univariate analysis and multivariate analysis were utilized to analyze the related factors of halitosis in children. Results:In the study, 34. 4% of the total subjects had excessive VSC. Hydrogen sulfide (H2S) [(1. 59 ± 2. 41) ng/10 mL] and total VSC concentration [(2. 14 ± 4. 42) ng/10 mL] in the girls were significantly higher (P<0. 05) than those in the boys. The tongue coating score had a significant positive correlation with H2S [tongue coating area (1. 68 ± 2. 48) ng/10 mL,tongue coating thickness (2. 18 ± 2. 69) ng/10 mL] and total VSC concentration [ tongue coating area, (2. 26 ± 4. 31) ng/10 mL,tongue coating thickness (2. 41 ± 3. 02) ng/10 mL , P<0. 01]. The site number of DI-S≥2 had a significant positive correlation with methyl mercaptan ( CH3 SH) and dime-thyl sulfide [(CH3)2S] concentration (P<0. 01). The concentration of H2S [(1. 19 ± 1. 62) ng/10 mL] in children, whose mother had a higher degree of education, was statistically lower (P<0. 01).The children who took dessert or sweat drinks more frequently had lower H2S [(1. 04 ± 1. 55) ng/10 mL, P<0. 05] concentration, while CH3SH and (CH3)2S concentration [(0. 29 ± 1. 92) ng/10 mL, (0. 37 ± 2. 06) ng/10 mL, P<0. 05) were higher in the children with mouth -breath habit. Conclu-sion:A high prevalence of halitosis was noted in preschool children. Gender, tongue coating index, deb-ris index-simplified, status of the mother' s education, frequency of eating dessert or sweat drinks and dry mouth breath were related with halitosis of preschool children. The different related factors resulted in changes of each VSC concentration.

The epitope-G1 gene of Bovine ephemeral fever virus (BEFV) glycoprotein was synthesised by PCR and cloned into expression vector pPIC9K to construct recombinant plasmid pPIC9K-G1. Then the pPIC9K-G1 was linearized and transformed into Pichia pastoris GS 115. The recombinant P. pastoris strains were selected by a G418 transformation screen and confirmed by PCR. After being induced with methanol, an expressed protein with 26 kDa molecular weight was obtained, which was much bigger than the predicted size (15.54 kDa). Deglycosylation analysis indicated the recombinant G1 was glycosylated. Western blot and ELISA tests, as well as rabbit immunization and specificity experiments indicated that the target protein had both higher reaction activity and higher immunocompetence and specificity. The recombinant G1 protein could be used as a coating antigen to develop an ELISA kit for bovine ephemeral fever diagnosis.

Objective: To observe the clinical efficacy of intradermal needle therapy for urinary retention after cervical cancer surgery. Methods: A total of 100 patients with urinary retention after cervical cancer surgery were randomized into a control group and an observation group, with 50 cases in each group. The control group was treated with basic nursing only, and the observation group was treated with additional intradermal needle therapy. Both groups were treated for 2 courses of treatment. The main symptom scores and residual urine volume of the two groups were observed before and after treatment, and the inpatient time, catheter indwelling time and the clinical efficacy were compared between the two groups. Results: The total effective rate was 96.0％ in the observation group and 88.0％ in the control group, and the difference between the two groups was statistically significant (P<0.05). After treatment, the main symptom scores and residual urine volume in both groups decreased significantly (all P<0.05), and the scores and residual urine volume in the observation group were significantly lower than those in the control group (all P<0.05). The inpatient time and catheter indwelling time in the observation group were significantly shorter than those in the control group (both P<0.05). Conclusion: Intradermal needle therapy has an obvious effect in improving symptoms of urinary retention after cervical cancer surgery, and the effect is significantly more persistent than that of simple basic nursing.

Objective To explore the variance of plasma brain natriuretic peptide (BNP) concentrations in the aged patients after noncardiac surgery and its significance. Methods 101 patients undergoing elective noncardiac surgery were divided into two groups based on the BNP concentrations before surgery: group A: BNP≤100 ng/L，n=61; group B: BNP>100 ng/L，n=40. The BNP concentrations before and after noncardiac surgery and the incidence of cardiac events in both groups were compared. Results There was no significant difference （P>0.05） of BNP concentrations before and after noncardiac surgery in group A, which were (58.2±28.7) ng/L and (53.7±25.9) ng/L respectively, but was significant difference （P<0.05） in group B, which were (147.3±72.1) ng/L and (341.5±92.4) ng/L respectively. There was significant difference （P<0.05） between group A, in which no patient happened cardiac event, and group B, in which 14 patients happened. Conclusion The plasma BNP concentration would be increased significantly in the aged patients with a BNP concentration>100 ng/L before surgery, which may cause more cardiac events.

OBJECTIVETo investigate the prognostic factors of lymph node-negative advanced gastric cancer patients in order to guide adjunctive therapy and surveillance tragedy.

METHODSA total of 236 advanced gastric cancer patients with no less than 12 retrieved lymph nodes and without lymph node metastasis from Fujian Provincial Hospital between 1998 and 2008 were collected retrospectively. Univariate and multivariate prognostic analysis were performed.

RESULTSTwo hundred and twenty-four patients(94.9%) were followed up and 5-year overall and disease-free survival rates were 75.2% and 66.4% respectively. Univariate prognostic analysis showed that depth of infiltration, Lauren histotype and retrieved lymph nodes were associated with 5-year overall survival(all P<0.05). Multivariate prognostic analysis testified that depth of infiltration was independent prognostic predictor(P<0.05). Recurrent rates of T2 and T3 patients were 5.8%(8/138) and 14.0%(12/86),5-year overall survival rates were 82.5% and 59.0%, 5-year disease-free survival rates were 70.4% and 52.2% respectively. These differences were all statistically significant (all P<0.05).

CONCLUSIONST2N0 gastric cancer patients have a better prognosis than T3N0 patients. Depth of infiltration should be considered to stratify lymph node-negative gastric cancer patients for an adjunctive treatment and follow-up scheduling.

Objective of this study was to detect the expression of HtrA2 and WT1 mRNA in acute myeloid leukemia (AML) and investigate the relationship of their expression levels with clinical variates and correlation between them. The expression levels of HtrA2 and WT1 were measured by RQ-PCR in bone marrow cells in 104 newly diagnosed AML patients and leukemia cell lines (K562, HL-60, NB4, Kasumi-1, U937), and the relationship between expression level and clinical parameters (age, sex, WBC count, diagnosis and prognosis) was investigated. The results showed that (1) the expression of HtrA2 gene in newly diagnosed AML was lower than that of the normal controls (P < 0.01), while expression of WT1 gene in newly diagnosed AML was higher than that of the normal controls (P < 0.01), the expression levels of HtrA2 and WT1 genes both did not correlate with age, sex and WBC counts of patients. There were no significant difference of HtrA2 gene expression between different NCCN prognosis group, while WT1 gene expression in better-risk group was significantly lower than that in intermediate-risk group (P = 0.003). The HtrA2 expression level rose after treatment in both CR group and non-CR group (P < 0.05), while WT1 expression level significantly decreased after treatment only in CR group (P < 0.01). Negative correlation between HtrA2 and WT1 expression was also observed (r = -0.249, P = 0.011). It is concluded that the low expression of HtrA2 and high expression of WT1 are closely related with occurrence and development of acute leukemia, so up-regulating expression of HtrA2 and interfering expression of WT1 may become the targets for leukemia therapy in the future.

AIMTo investigate the pharmacokinetic characteristics of recombinant human acidic fibroblast growth factor (rhaFGF) after external use in rabbits.

METHODS125I-rhaFGF 180 U.cm-2 was daubed to normal skin and scathed skin in rabbits. The radioactivity and paper chromatography were used to determine the 125I-concentrations and distribution in plasma and organs at different times.

RESULTSThe plasma concentration of 125I-rhaFGF increased rapidily, and reach peak plasma level (73.03 pg.mL-1) thirty minutes after administration. Then the concentration of 125I-rhaFGF decreased quickly after thirty minutes, and approached to zero after three hours. Highest radioactivity accumulated in the skin, followed by kidney, lowest in the brain 96 h after administration.

CONCLUSIONrhaFGF can not be absorbed from the normal skin, whereas a small amount of rhaFGF can be absorbed through scathed skin. The t1/2 of rhaFGF in plasma was very short. Cumulative effect of rhaFGF was not observed. Absorbed rhaFGF showed high affinity to skin, and can be distributed to skin far from the site of administration.

Receptors play a crucial role in determining the host specificity and tissue tropism of virus. Foot-and-mouth disease virus(FMDV)has been showed to use four integrins, ?v?1, ?v?3, ?v?6 and ?v?8 as receptors to initiate infection and ?v?6 functions as the major receptor.The cDNA encoding bactrian camel integrin ?6 from the lung tissue was cloned and sequenced. The 2367bp cDNA of bactrian camel integrin ?6 encodes a polypeptide of 788 amino acids consisting of a 26-residue putative signal peptide, a 681-residue ectodomain with 8 potential N-linked glycosylation sites and 58 cysteine residues, a 29-residue transmembrane domain, and a 52-residue cytoplasmic domain with a NPLY motif and 1 potential N-linked glycosylation site. The nucleotide sequence similarity of integrin ?6 between bactrian camel and cattle, pig, sheep, human, mouse, Norway rat is 91.1%、91.8%、90.6%、90.5%、83.7%、84.1%, and the amino acid sequence similarity is 94.3%、93.4%、93.4%、93.7%、88.7%、88.6%, respectively. The bactrian camel ?6 gene exhibited the higher sequence homology with the ?6 gene of cattle, pig and sheep, indicating their close genetic relationships. It is possible that host tropism of FMDV may related to divergence in ?6 receptors among different species.
