Objective To observe the effect of health education and installation of improved stove in control of coal-burning-borne endemic fluorosis in Pingba County of Guizhou Province.Methods Two towns(Shizi and Qibo) of Pingba County that had implemented the health education and installed the improved stoves for control of coal-burning-borne endemic fluorosis were selected as the investigation sites.Two villages in each selected town and 30 householders as well as all students of grade 4-6 were investigated.Questionnaires were made by survey of the fluorosis control knowledge,household investigations were used to know the use of household stoves,corn and peppers drying method,and the dental fluorosis of children aged 8-12 were examined by Dean methods before the intervention(2006) and after implementation(2009) of health education and improvement of stoves.Results The awareness of fluorosis control among students and households after the intervention was 97.36％ (405/416) and 86.46％(415/480),respectively,and the difference was statistically significant(x2 =658.86,163.10,all P ＜ 0.01) compared with that before the intervention [32.19％(1083/3364),43.33％(130/300)].Correct using rate of the household stoves was 95.42％ (229/240) after the intervention and 45.85％ (3976/8672) before the intervention,the difference was statistically significant(x2 =230.25,P ＜ 0.01).The correct rates of drying corn and chili were 91.67％ (110/120) and 97.50％ (117/120) before the intervention,and 20.00％ (12/60),26.67％ (16/60) after the intervention,the difference was statistically significant(x2 =94.07,104.02,all P ＜ 0.01).The incidences of dental fluorosis of children aged 8-12 were 31.21％(1305/4182) after the intervention and 87.71％(2856/3256) before the intervention,the difference was statistically significant(x2 =2371.91,P ＜ 0.01).Conclusions The measures of health education and intervention of stove improvement in Pingba County of Guizhou Province for prevention and control of coal-burning-borne endemic fluorosis is effective.

OBJECTIVETo compare the differences in the efficacy on lower limb motor function in children with spastic cerebral palsy between the combined therapeutic program of Jin three-needle therapy and MOTOmed intelligent motor training and the simple MOTOmed.

METHODSEighty children with spastic cerebral palsy were randomized into an observation group and a control group, 40 cases in each group. In the observation group, Jin three-needle therapy was used at four mind points, three brain points, three intelligent points, three temporal points, three knee points and three foot points, as well as Chengjin (BL 56), Chengshen (BL 57) and the other. Additionally, MOTOmed was given in assistance with conventional rehabilitation training. In the control group, MOTOmed and the conventional rehabilitation training were adopted. In the two groups, the treatment was given once a day, 20 treatments made one session and there were 3 to 5 days at interval between the two sessions. The efficacy evaluation was performed after continuous 3 sessions of treatment. The gross motor function measure (GMFM) and modified Ashworth scale (MAS) were applied for the evaluation before and after treatment in the two groups.

RESULTSAfter 3 sessions of treatment, GMFM score was increased apparently as compared with that before treatment in the two groups (P < 0.01, P < 0.05). After treatment, GMFM score in the observation group was increased more remarkably than that in the control group (55.32 +/- 17.10 vs 47.48 +/- 17.18, P < 0.05). After treatment, the total effective rate of gastrocnemius Ashworth spasm grade [90.0% (36/40)] in the observation group was better apparently than [72.5% (29/40)] in the control group (P < 0.05).

CONCLUSIONThe combined therapeutic program of Jin three-needle therapy and MOTOmet intelligent motor training improves the lower limb motor function of the children with spastic cerebral palsy and its efficacy is better than simple MOTOmed.

Objective To estimate the effect of glycoprotein (transmembrane) nonmetastatic melanoma protein B (GPNMB) on the proliferation and migration of as well as melanogenesis in melanoma cells.Methods The expression of GPNMB was detected by immunofluorescence assay in two melanoma cell lines M14 and G-361,as well as in primary human melanocytes.Then,the three kinds of cells each were classified into three groups:experimental group treated with small interfering RNA targeting GPNMB (GPNMB-siRNA),negative control group treated with the negative control siRNA,blank control group remaining untreated.Methyl thiazolyl tetrazolium (MTT) assay,transwell invasion assay and spectrophotometry were performed to evaluate cell proliferation activity,invasion potential and melanin levels,respectively.Statistical analysis was done using Student's t test.Results GPNMB was expressed in both melanoma cells and melanocytes.The transfection with GPNMB-siRNA down-regulated the mRNA and protein expressions of GPNMB in,and markedly suppressed the proliferation and migration of,melanoma cells.In detail,the proliferative activity (expressed as the absorbence value at 570 nm) of M14 and G361 cells was reduced by 35％ and 40％ respectively,the migration activity of M14 and G361 cells by 49％ and 51％ respectively,and the melanin levels in melanocytes,M14 cells and G361 cells by 73％,82％ and 69％ respectively,in the experiment group compared with those in the blank control group.Conclusions The siRNA-mediated silencing of GPNMB could effectively inhibit the proliferation of,invasion of and melanogenesis in melanoma cells,which suggests that GPNMB plays critical roles in the initiation and progression of melanoma.

Objective To investigate changes of brainstem auditory evoked potential (BAEP)and somatosensory evoked potential (SEP) in patients with acute cerebral infarction,and discuss their relation with prognosis of the patients.Methods The study involved 60 patients with acute cerebral infarction.Changes of BAEP and SEP in each patient were detected and recorded continuously.Prognosis evaluation was performed by using GCS.Another 60 age-matched and gender-matched healthy human beings were enrolled as controls.Results Incubation period of BAEP wave Ⅰ had no significant difference between the cerebral infarction and control groups (P ＞ 0.05).However,interspike intervals of other BAEP waves in cerebral infarction group were different from those in control group (P ＜ 0.05).A series of waves of SEP (P14-N60) were all significantly prolonged in cerebral infarction group (P ＜0.05).Conclusion BAEP and SEP can effectively reflect function of brain stem in patients with acute cerebral infarction and have some values in determining their prognosis.

We used 4 methods,such as ultrasonic crush(UC),ultrasonic rinse(UR),whorl surge(WS)and rubbing(RU),to isolate epiphytic bacteria from red alga Gracilaria lemaneiformis.Then,we counted bacteria numbers,detected bacterial species,observed bacterial configuration and characteristic of cell wall.Compared with these methods and with different treatments in one method,the results were drawn:the UR and RU were inferior in all methods to isolate bacterial numbers and species,the UC and WS were better,especially,the treatment 30W 30s of UC was the best in experiment,which isolated 12 of 16 bacterial species,and got 1.75 10~6 cells per gram wet weight G.lemaneiformis.

Objective To study the relationships between hepatocellular carcinoma (HCC) and the polymorphisms,promoter methylation,and expression of glutathione S-transferases P1 gene (GST) P1 gene.Methods Using methylation-special PCR (MSP),the methylated status of CpG islands of GSTP1 gene in tumor tissues of 53 HCC and its adjacent nontumor tissues were studied.The enzyme activities of GSTP1 were evaluated by ultraviolet colormetry.And using PCR-RFLP,the genetic polymorphisms of the GSTP1 genes of 74 healthy controls and 53 HCC patients were studied.Results The diffe-rences of the frequency of GSTP1 Ile/Ile,Ile/Val and Val/Val genotypes between HCC patients and the normal controls did not reach statistical significance (X~2=0.84,v=2,P=0.656).The frequency of methyla- tion of CpG islands of GSTP1 gene was significantly higher among the HCC tumor tissues when com- pared to the corresponding nontumor tissues (X~2=19.08,P＜0.001),and significantly higher in stageⅢ-Ⅳcases when compared to the stageⅠ-Ⅱcases (X~2=4.84,P=0.028).GSTP1 enzyme activities of cytoplasm in tumor cells were lower significantly than that in the adjacent nontumor tissues (t=2.49, P=0.014),and significantly higher in stageⅠ-Ⅱcases when compared to the stageⅢ-Ⅳcases (t= 2.31,P=0.025).On the other hand,the GSTP1 enzyme activities of cytoplasm in tumor cells with methylated status of GSTP1 gene were significantly lower than that in tumor cells with unmethylation (t=3.50,P=0.001).Conclusion GSTP1 inactivation via CpG island hypermethylation may contrib- ute to the pathogenesis of HCC.
