OBJECTIVETo explore the psychosocial effect of fluorosis on patients in fluorosis epidemic areas.
METHODSMultistage, stratified, clustered and random sampling method was used in this survey. Totally 416 inhabitants of 12, 15 and 35-44 years of age from rural fluorosis epidemic areas in Hebei province were selected. Dental fluorosis was classified by Dean's index (DI). A total of 178 patients with different types of fluorosis were involved in a psychosocial questionnaire investigation which included six five-point subscales, including attitude to teeth, subjective well-being, life satisfaction, interpersonal or social anxiety, effect of self-esteem, impact on behavior.
RESULTSFluorosis prevalence in fluorosis epidemic areas of Xingtai in Hebei province was 71.20%, and significant difference existed among three age groups (Pearson Chi-square value = 167.51, P < 0.01). With the increase of DI score, the average value of subscale "attitude to teeth" rising, ranging from 2.58 to 3.51, and value of "subjective well-being" was also increasing, ranging from 2.35 to 2.9. Statistical difference of subscale average value was found only in these two subscales ("attitude to teeth": F = 4.787, P < 0.01; "subjective well-being": F = 2.538, P < 0.05). "Attitude to teeth" was significantly different between control group and moderate group (F = 0.52, P < 0.01) and between control group and severe group (F = 0.72, P < 0.01). While significant difference of "subjective well-being" could only be found between control group and severe group (F = 0.56, P < 0.01). According to the bivariate correlation analysis, strong correlation could be found between the degree of fluorosis and the average value of sub-scales.
CONCLUSIONSThe psychosocial impact of fluorosis on patients in fluorosis epidemic areas mainly appeared in two aspects, i.e. attitude to teeth and the perception of well-being, especially in severe group.

OBJECTIVETo explore the in vitro anti-tumor effect and mechanism of dendritic cell (DC) tumor vaccine induced by astragalus polysacharin (APS).
METHODSPeripheral blood mononuclear cells (PBMCs) isolated from human peripheral blood. DCs obtained from human peripheral blood were cultivated and added with culture solution for in vitro inducing them to immature DCs. On the 5th day of culture, 100 microg/mL (as the final concentration) APS was added to cells in the APS group. DCs were induced to mature in the cytokine groups by adding 20 ng/mL rhTNF-alpha (as the final concentration). Changes of morphology and phenotype of DCs were observed. Mature DCs were sensitized with tumor antigen SGC-7901 and co-cultured with allogeneic T cells. The proliferative function of T lymphocytes was detected by MTT assay. Levels of IL-12 and IFN-gamma in co-cultured supernatant were detected by ELISA. Cytotoxic lymphocytes (CTL) activated by DC were co-cultured with tumor cell SGC-7901. The specific killing capacity of CTL to target cells was detected by LDH release assay.
RESULTSThe morphological observation and phenotypic identification of APS induced DCs were in accordance with the characteristics of mature DCs. APS induced mature DCs could stimulate the proliferation of allogeneic T lymphocytes. The proliferation index of T cells increased with increased ratio of stimulator cells to effector cells (P < 0.05). Levels of IL-12 and IFN-gamma in co-culture supernatant significantly increased in a time-dependent manner (P < 0.05). CTL cells activated by sensitization of DCs could significantly kill tumor cells, and the killing effect increased along with increased effector-to-target ratio.
CONCLUSIONAPS could in vitro induce DCs to mature, promote its antigen-presenting capacity, effectively activate CTLs, and enhance anti-tumor function of the organism.

To study the varieties of adhesives in gels on the basis of previous studies, dosage of adhesives required for forming of gels by using the single factor design, as well as the drug loading capacity of gels with the adhesiveness and stickiness as the scoring indicators, in order to determine the forming method of analgesic micro-emulsion gel. Subsequently, the improved Franz diffusing cell method was adopted to study the release of water-soluble components and liposoluble components in analgesic gels, with imperatorin and ferulic acid as index components. The results showed that analgesic micro-emulsion gel could promote the release of imperatorin and ferulic acid. Finally, HPLC was used to detect that the loss amount of volatile components in analgesic micro-emulsion gel was 23.13% lower than that in the original analgesic gel. In the experiment, we finally prepared finished products of micro-emulsion gel, discovered that the micro-emulsion technology is helpful to improve the synchronous release of water-soluble components and liposoluble components in prescriptions and can reduce the loss of volatile components.

OBJECTIVETo investigate the expressions of nestin and vascular endothehal growth factor (VEGF) mRNAs in rat brain tissue after cerebral ischemia-reperfusion injury and their changes in response to Tongxinluo (a traditional Chinese herbal preparation) treatment.
METHODSCerebral ischemia was induced in rats by temporary middle cerebral artery occlusion (MCAO) followed by treatment with Tongxinluo at high and low doses. On days 3, 7, 14 and 21 after MCAO, nestin and VEGF mRNA expressions in the ependyma, subventricular zone (SVZ), and hippocampal subdentate gyrus zone (HDG) in the ischemic hemisphere were quantitatively analyzed using immunohistochemistry and RT-PCR.
RESULTSCompared with the sham-operated group, the rats with cerebral ischemia-reperfusion injury showed significantly increased nestin-positive neurons and VEGF mRNA expression in the SVZ and HDG 7, 14 and 21 days after MCAO (P<0.05). Treatment with Tongxinluo, especially at high doses, significantly increased the number of nestin-positive neurons and VEGF mRNA expression in the rats 7, 14 and 21 days after MCAO (P<0.05).
CONCLUSIONFocal cerebral ischemia in rats results in rapid response and proliferation of neural stem cells in the SVZ and HDG in the ischemic hemisphere possibly by increasing VEGF mRNA expression in the adjacent tissues around the ischemic focus. Tongxinluo may enhance the differentiation and proliferation capacity of the neural stem cells after MCAO by inducing the expression of VEGF mRNA.

OBJECTIVETo rudiment analyze the different intervention factors affecting the spinal cord injury functional recovery initially through prospective study project.
METHODSDesigned prospective study project without clinical treatment intervention and admitted 62 spinal cord injury cases into observation group from Dec 2006 to Dec 2007. The internalized standard included acute spinal cord injury within 1 week, aged from 18 to 65 years old without sexuality difference and diagnosed as type A injury: total spinal cord injury or type B injury: non-total spinal cord injury (without movement function below the injury plane) according to clinical physical examination and combined MRI or CT examination. All the 62 cases were followed up. The spinal cord function were estimated at the time of arriving hospital, 1, 3, 6 months after injury during the following up time according to the American Spine Injury Association standard (Revised at 2000) and functional independence measure (FIM) score. The intervention factors affecting the spinal cord injury functional recovery were analyzed.
RESULTSAmong the 62 cases, male 60 cases and female 2 cases, aged from 18 to 41 years old, mean age 24 years old, 29 cases can be classified into type A injury and 33 cases can be classified into type B injury. There was no significant difference (Index including sense ASIA, motor ASIA and FIM) between operation group and non-operation group, namely conservatively composite treatment at all observation point in all type A injury cases (P > 0.05). There was significant difference (Index including sense ASIA, motor ASIA and FIM) between operation group and non-operation group at all observation point in all type B injury cases (P < 0.05); And there was significant difference (Index including sense ASIA, motor ASIA and FIM) between operated in 8 hours (< or = 8 h) group and beyond 8 hours (> 8 h) group at all observation point in all type B operated cases (P < 0.05).
CONCLUSIONSOperation and operation time were of no significant value for type A injury (total spinal cord injury), but considering the nursing convenience and the need for spinal stabilities, operation decompression and internal fixation can be chosen; Operation decompression should be performed as soon as quickly for type B injury (non-total spinal cord injury) in order to get better functional recovery.
