10 mU/L (GroupⅡ,71 cases) when they were one year old.There were 40 healthy children in control group. The genomic DNA from the peripheral blood was extracted and polymerase chain reaction (PCR) and sequencing were employed to detect the IL-12B gene 3′UTR+1188 SNP.Results The frequency of AA,AC and CC genotype in GroupⅠwere 25.7%,44.3% and 30.0% respectively,and 36.6%, 47.9% and 15.5% in GroupⅡ,48.8%,39.0%,12.2%,in control group,respectively.The differ- ence of frequency of CC genotype and non-CC genotype between GroupⅠand GroupⅡwas significant (x~2=17.078,P

OBJECTIVE:To evaluate the rationality of vancomysin use in the hospital where the authors work.METH-ODS:50patients taking vancomysin between May.2005and Nov.2005were studied.The pathogenic examination,monitoring of drug concentration in blood,indices of renal function,combined use of drugs as well as adverse effects in these patients were reviewed and analyzed statistically.RESULTS:On the whole vancomysin use in our hospital was safe.CONCLUSION:Vancomysin use will be made safer by monitoring drug concentration in blood,individualizing drug administration,and timely correcting the aggravating factors of kidney injury.

Objective To investigate the effects of baicalin on the apoptosis and cell migration of intestinal epithelial cells 6 (IEC-6) induced by lipopolysaccharide (LPS) . Methods LPS was adopted to establish LPS-induced cells injury model. Methyl thiazolyl tetrazolium ( MTT) assay and Elisa kits were used to evaluate the effect of LPS on the tumor necrosis factor alpha ( TNF-α) and interleukin 6 ( IL-6) concentrations of IEC-6. Hoechst 33258 staining and flow cytometry were used to evaluate the effect of baicalin ( in the dosage of 2.5, 5.0, 10.0 μg/mL ) on the cell apoptosis. Cell migration was observed and calculated on a wounding model of IEC-6 cells induced by a pipette tip. Results Compared with the control group, the survival rate of IEC-6 in 1.0 μg·mL-1 LPS group was much lowered, TNF-α and IL-6 concentrations were significantly increased, the apoptotic rate of IEC-6 was increased and the cell migration activity was significantly decreased ( P<0.05) . Compared with the model group, IEC-6 apoptosis was relieved to various degrees in baicalin groups, the apoptotic rate of IEC-6 was obviously decreased (P<0.05) and cell migration activity was increased significantly (P<0.01) in 10.0 μg·mL-1 baicalin group. Conclusion Baicalin has the capacity of protecting IEC-6 from LPS-induced injury and increasing cell migration activity.

AlM: To study the therapeutic effect of external-route microsurgery forrhegmatogenous retinal detachment.
METHODS: ln 55 patients ( 55 eyes ) with rhegmatogenous retinal detachment, drainage of subretinal fluid, examination of locating the holes, sclera cryotherapy, scleral buckling, and vitreous cavity injection of filtrated air were performed under surgical microscope.
RESULTS:The retinal reattachment occurred in 50 cases after the primary surgery. The final rate of reattachment was 91% during 6 - 12mo follow - up. The retinal reattachment occurred in 1 case ( recurrent retinal detachment) after the secondary surgery and in 4 cases ( recurrent retinal detachment ) after vitrectomy. The eyesight was improved with different degrees in 55 cases.CONCLUSlON: The external- route microsurgery for rhegmatogenous retinal detachment is simple, safe and effective.

ObjectiveTo explore the prevalence state of children in coal-burning borne endemic fluorosis in Fuyuan county Qujing city,to know the implementation of preventing measures,and to provide a scientific basis for prevention of endemic fluorosis.MethodsIn 2009,105 families were sampled to check the service condition of defluoridation stove and the effect of health education (the awareness of use defluoridation stove reasons) in Xiaoyuwang,Tuoga and Shaliang villages,Fucun town of Fuyuan county.Food fluorine of indoor stored peppers and corns was monitored of 20 families in Xiaoyuwang village,5 household were randomly selected from east,west,south,north and middle places of the village.Air fluorine was monitored from indoor air samples of 5families,dental and urinary fluorine was monitored of the native-born children aged 8 to 12,and dental fluorosis of these children was checked.Clinical endemic fluorosis and X-ray endemic fluorosis was monitored of local adult residents over the age of 30 that had been lived in the area for more than 5 years.ResultsThe rate of correct use of the defluoridation stove was 100％,and adult awareness rate of use defluoridation stove reasons was 82.86％(87/105).Of the 19 pepper samples,fluorine content were 9.98 - 538.40 mg/kg and median was 32.38 mg/kg,all exceeded the standard(1.5 mg/kg).Of the 25 corn samples,fluorine content were 0.42 - 101.54 mg/kg and median was 6.32 mg/kg,with 18 samples exceeded the standard(1.0 mg/kg).Of the 6 air samples,fluorine content were 0.000 98 - 0.003 33 mg/kg and median was 0.001 45 mg/kg.Detection rate of dental fluorosis of children aged 8 - 12 was 42.3％,urinary fluorine content were 0.13 - 1.80 mg/L,geometric mean was 0.58 mg/L,4 adults were diagnosed clinical skeletal fluorosis,detection rate was 2.46％(4/162),5 adults were found by X-ray with endemic fluorosis,detection rate was 9.61％(5/52).ConclusionPeppers and cons fluorine pollution is serious,general public should be guided to change their lifestyles to minimize the fluorine pollution.
