Objective To understand the situation of iodine deficiency disorders of Cangzhou city, Hebei province, in order to provide the scientific basis for prevention and control of iodine deficiency disorders. Methods From 2007 to 2009, dynamic monitoring of iodine deficiency disorders was carried out in low iodized salt coverage places Hejian city and Xian county. Nine towns were randomly chosen in each county, 4 administrative villages were randomly selected in each town, 8 household salts were tested in each village. Every year, 1 - 3 copies of residents water samples were collected for determination of iodine; more than 100 students age 8 - 10 years old were checked the situation of goiter and urinary iodine, more than 40 students selected were measured iodine content of salt from their home; more than 50 women of childbearing age 18 - 40 years were tested of urinary iodine. Thyroid was examined with palpation; water iodine and urine iodine concentration were measured with arsenic-Ce catalytic spectrophotometry; salt iodine was detected by direct titration. Results From 2007 to 2009,median household salt iodine were 4.3,15.9,3.6,18.4,4.6,11.7 mg/kg in Hejian city and Xian county, respectively,iodized salt accounted for 34.03% (98/288), 78.82% (227/288), 29.86% (86/288), 84.72% (244/288), 37.15%(107/288),49.31% (142/288), respectively, the consuming rate of iodized salt were 27.08% (78/288),36.46%( 105/288 ), 28.13% (81/288 ), 49.31% ( 142/288 ), 37.15 % ( 107/288 ), 30.90% ( 89/288 ), respectively. Ten samples of drinking water were tested, water iodine were 5.5 - 34.4 μg/L. From 2007 to 2009, the goiter rate of students aged 8 - 10 years old was below 5%, the median of urinary iodine were 138.1,176.6,112.0 μg/L, ＜ 100 μg/L ratio were 31.6% ( 65/206 ), 25.0% ( 52/208 ) and 44.4% (91/205 ). The median of urinary iodine of child-bearing age women were 167.3,164.2,78.1 μg/L, ＜ 100 μg/L ratio were 28.7%(29/101 ), 19.2%(20/104) and 60.0%(60/100).Conclusions In areas with low coverage of iodized salt, iodine nutrition level are affected, the child-bearing age

ObjectiveTo analyze the relationship between clinical characteristic pathology and prognosis in infant with intra-abdominal solid tumor.MethodsFifty-two infants(less than 1 year old) with abdominal solid tumor from Apr.1998 to Feb.2007 in Shanghai Children's Medical Center and from Jan.2001 to Feb.2007 in Shanghai Xinhua Hospital were reviewed.The history of these children were reviewed.Features and clinical pathology of these children with their prognosis were analyzed and followed up by telephones and children return visit records from 5 months to 8 years.ResultsLess than 1 month,7 cases;1 month to 1 year old,45 cases.Teratoma 23 cases(44.23%),neuroblastoma 9 cases(17.31%),nephroblastoma 6 cases(11.54%),hepatoblastoma 5 cases(9.62%),epithelioid hemangioendothelioma of the liver 3 cases(5.77%),congenital mesoblastic nephroma 3 cases(5.77%),fusiform cell epithelioid hemangioendothelioma of pancreas 1 case(1.92%),hamartoma of the liver 1 case(1.92%),retroperitoneal small cell malignant tumor 1 case(1.92%).Benign:malignant=1:1.Among the benign tumor,male:female=1:1.Among the malignant tumor,male:female=2.33:1.0.All children were treated with tumor resection,and combined with chemotherapy for those whose tumors were malignant.ConclusionsAmong infant abdominal solid tumors,teratoma and neuroblastoma are much more than other tumors.The cases of benign tumors are almost as much as the malignant tumors.The benign tumors did not have sex differences,and had good prognosis after surgical resection.However,in malignant tumors,the incidence rate of male is obviously higher than female.Completely resection of those malignant tumors with chemotherapy would get little incidence of recrudescence and low case fatality rate.Early diagnosis and early treatment play an important role in prognosis.

Objective To compare the clinical efficacy between continuous and intermittent androgen deprivation in high risk prostate cancer.Methods Sixty-four patients with high risk prostate cancer were treated from January 2008 to April 2009,36 cases who accepted goserelin and bicalutamide were taken as intermittent hormonal therapy (intermittent treatment group),while 28 cases who accepted bilateral orchiectomy in addition to flutamide were regarded as continuous hormonal therapy (continuous treatment group).The comparison of tumor specific mortality,time of prostate specific antigen (PSA) to nadir,tine to PSA recurrence,serum testerone and quality of life score were assessed between the two groups.Results In continuous treatment group and intermittent treatment group,follow-up period was (26.4 ± 10.3) and (28.1 ± 8.7) months,the time of PSA to nadir was (3.8 ± 2.1 ) and (4.0 ± 3.6) months,the time to PSA recurrence was (20.1 ± 12.3) and (24.5 ± 14.6) months,respectively.There was no significant difference between the two groups.At the time of 18,24 and 30 months after therapy,serum testerone was 0.85,0.88,0.89 μg/L in continuous treatment group,while 1.21,1.36,1.48 μg/L in intermittent treatment group,respectively (P ＜ 0.05 ).Similarly,quality of life score was 38.7,40.5,39.8 scores in continuous treatment group,while 49.2,51.4,52.3 scores in intermittent treatment group at the time of 12,18 and 30 months after therapy,respectively (P ＜ 0.05 ).Conclusions Clinical efficacy could not been found between continuous and intermittent endocrinic therapy of prostate cancer.During intermittent,quality of life seems to be better and increases in accordance with serum testerone recurrence at given time.

Objective To evaluate the influential factors of iron acquisition during Francisella tularensis LVS infection of mouse macrophages.Methods F.tularensis LVS expressing green fluorescent protein was used to infect murine macrophage J774A.1 cells.Transferrin receptor 1(Tfr1)was detected with mono-antibody and visualized with a goat-anti mouse IgG conjugated to Alexa 594.The expression profile of 5 iron metabolism related genes of J774A.1 murine macrophages uninfected or infected with F.tularensis LVS was determined with real-time PCR.Immunoblot analysis was used to compare the Tfr1 expression of live Francisella infected macrophage with dead bacteria.Tfr1 knock-off in J774A.1 cells was performed with siRNA.The transfected cells were infected with Francisella for immunoblotting and microscopy and infection assay.Results It was revealed that the live vaccine strain of F.tularensis induced the expression of Tfr1 in host macrophages.Gene expression analysis indicated that F.tularensis LVS drove an active iron acquisition program with induction of Tfr1 and iron regulatory proteins(Irp1 and Irp2).It was shown by Western-blotting that the siRNA-Tfrc-1 could knock off about 75% of Tfr1 in J774A.1 cells.It was determined by infection assay that,Tfr1 was knocked off,the bacteria number at 1h infection with Francisella was not different from that of control(F=1.06,P=0.326 5),while it was decreased significantly after 24h of infection(F=24.12,P=0.000 6).Conclusions It is demonstrated that upregulation of the Tfr1 may be mediated by post-transcriptional regulation during early infection,but sustained later through increased expression of Irp 1 and Irp 2.Increased expression of Tfr1 expands the intracellular iron pool through transferrin-mediated delivery and may thus be readily available for uptaking by Francisella.Knocking off the expression of Tfr1 does not affect bacterial invasion.Francisella,however,may fail to proliferate in macrophages in which the expression of transferrin receptor has been suppressed.

OBJECTIVETo observe the effect of fluoride drop or fluoride ion infiltration on demineralization of the first permanent molar of children.

METHODS45 children applied by fluoride drop over 3 years in Chengdu and 40 controls were selected. 45 children applied by fluoride ion infiltration more than 3 years in Xiamen and 40 controls were selected in this study. Demineralization of the different sites of the first permanent molar was evaluated by KaVo DIAGNOdent. The effect of FD and FII in toddler period on demineralization of the first permanent molar was evaluated.

RESULTSEarly demineralization of the first permanent molar in children without fluoride drop were more severe than that of children with fluoride drop in toddle period (P < 0.01). There was no significantly difference between demineralization of first permanent molar in children with fluoride ion infiltration and control group (P > 0.05).

CONCLUSIONFluoride drop in toddle period can help the remineralization of newly erupted first permanent molar of children. There is no effect of fluoride ion infiltration on demineralization of newly erupted first permanent molar of children.

Objective To investigate the relationship between bladder outlet obstruction(BOO) and serum prostatic specific antigen(PSA) in patients with benign prostatic hyperplasia(BPH).Methods The study of pressure-flow urodynamic examination,IPSS score and serum PSA were performed in 253 cases with BPH.Results Based on the bladder outlet obstruction index(BOOI),all patients were divided into three groups: Definite BOO group had 156 patients,mild BOO group had 61 patients,no BOO group had 36 patients.The data of tPSA were(4.54?1.71) ?g/L,(2.45?1.74) ?g/L and(1.85?1.71) ?g/L respectively,there were significant differences between definite BOO group and other two groups(P0.05).Conclusion As a easy detection index,serum PSA may partially reflect the severity of BOO,combined with IPSS score,uroflow, type of B supersonic wave,it would give some guide for patients with BPH to select therapies and judge the prognosis.

Objective To explore the effect of recovery sleep on the executive function after 36 h of total sleep deprivation by event related potential technology.Methods Thirteen healthy male college students participated in two trials. At the first trial normal sleep as control was investigated. At the second trial participants experienced 36 h of sleep deprivation and then accepted 8 h recovery sleep. In each trial six Go/Nogo tests were employed to test the executive control function and the ERP data were recorded. Results There was no statistical difference in behavior and ERP results at each time point as the subjects had normal sleep. After 36 h of sleep deprivation, the behavior results were statistically significant when compared to the baseline. The amplitude and latency of Nogo-N2, Nogo-P3 on Fz electrode, the amplitude and latency of Nogo-P3 on Cz electrode showed statistical significance when compared to the baseline. After 8 h recovery sleep, the average correct reaction time and the Go correct reaction rate had statistical significance compared to 36 h value. The amplitude of Nogo-N2 and Nogo-P3 had no statistical significance compared to the baseline.However,it was of statistical significance[(-6.80 3.95)vs(-3.37 2.63)μV,(10.63±6.62)vs(5.63±5.45)μV,(9.49±7.37)vs(6.08±6.56)μV] compared to 36 h value. The latency of the recovery value of Nogo-N2 and Nogo-P3 was statistically significant[(254.14±15.55)vs(243.08±13.97)ms(382.14±41.07)vs(349.17±30.36)ms,(369.86±26.48)vs(347.48±29.24)ms]compared to the baseline.Conclusion As the time of sleep deprivation is prolonged, the executive function is impaired and the executive function is not completely recovered after 8 h recovery sleep.

This research is to study the relationship between HPLC fingerprints of Moutan Cortex, Paeoniae Radix Rubra and Paeoniae Radix Alba and their activity on lipopolysaccharide-induced acute lung injury. HPLC fingerprints of each extract of Moutan Cortex,Paeoniae Radix Rubra and Paeoniae Radix Alba were established by an optimized HPLC-MS method. The activities of all samples against protein and tumor necrosis a factor were tested by the model of lipopolysaccharide-induced acute lung injury. The possible relationship between HPLC-MS fingerprints and the activitieswere deduced by the Partial least squares regression analysis method. Samples were analyzed by HPLC-MS/MS to identify the major peaks. The results showed that each sample had some effect on acute lung injury. Four components with a lager contribution rate of efficacy were calculated by the research of spectrum-effect relationship. Moutan Cortex exhibited good activity on acute lung injury, and gallic acid, paeoniflorin, galloylpaeoniflorin and paeonol were the main effective components.

WRKY transcription factor is one of the Zinc finger proteins which contains a highly conserved WRKY domain and is a family of the plant-specific transcription factor. The plasmid pET28a-SmWRKY1 harboring Salvia miltiorrhiza WRKY1 (SmWRKY1) gene was successfully transformed and expressed in Escherichia coli BL21 (DE3). The conditions on protein expression of SmWRKY1 in E. coli, including induction duration, temperature, IPTG concentration and the E. coli concentration were optimized. The results showed that the highest protein expression of SmWRKY1 was obtained at 24 hours after the E. coli was cultured in the presence of 0.2 mol x L(-1) IPTG at 20 degrees C with A600 values of 1.0-1.5. This recombinant histidine-tagged protein was expressed at 2.454 g x L(-1) as inclusion body, which was first extracted using urea, and then purified by Ni2+ affinity chromatography and identified by SDS-PAGE. The expression of SmWRKY1 in E. coli was further confirmed by western blotting analysis.
