ObjectiveTo investigate current iodine nutritional status of different groups of people in Harbin city, and to provide the basis for development of salt iodization standard and scientific iodine supplementation.MethodsThree urban districts and three surrounding counties were chosen in Harbin,2011.In each chosen urban district and county,one district office (township) was selected,and one residents committee (village) was chosen in each of the district office(township),and 30 households were selected by systematic sampling.Iodized salt,water iodine and iodine intake per capita were investigated.In each of the residents committee (village),20 adults aged 18 - 45,30 pregnant women or lactating women,and 100 school children aged 8 - 10 were selected.Urine samples were collected and urinary iodine level were tested.Salt iodine was determined by direct titration,water and urinary iodine by arsenic cerium catalytic spectrophotometry.Iodine uptake and iodine nutritional status of different populations in Harbin urban and rural areas were compared.ResultsThe edible rate of qunlified iodized salt were 93.3％(84/90) and 96.3％(156/162) in Harbin urban and rural residents,respectively,which were all greater than 90％,and the highest value of salt iodine were 38.3,46.0 mg/kg,respectively,in urban and rural areas,which all did not exceed the upper limit(50 mg/kg) of qualified iodized salt,but there were some samples of salt iodine content below the national standard(20 mg/kg).Water iodine value in urban and rural areas,even the highest value(9.40,8.40 μg/L),was failed to meet the national standard 10 μg/L; salt eaten by rural people perperson a day(8.33 g) was significantly higher than that of the urban people(7.03 g,Z=- 2.750,P ＜ 0.01); in addition to rural children aged 8 - 10,whose urinary iodine value(228.6 μg/L) was higher,the values in urban and rural adults ( 111.3,195.6 μg/L),pregnant women ( 193.0,172.9 μg/L),lactating women ( 128.4,173.7 μg/L)and urban children ( 186.8 μg/L ) were all in appropriate level.The urinary iodine medians ( 195.6,228.6 μg/L )of adults and children in rural were significantly higher than that of urban adults and children(111.3,186.8 μg/L,Z =- 2.294,- 5.434,P ＜ 0.05 or ＜ 0.01,respectively).Population composition of iodine deficiency in both urban and rural adults,lactating and pregnant women[46.7％(28/60),21.6％(13/60) ; 21.1％(19/90),21.3％ (18/89) ; 27.8％ ( 25/90 ),42.2％ (38/90) ] were significantly higher than that of the population composition with iodine excess[4.6％(4/60),5.0％(3/60) ; 16.7％(15/90),16.9％(15/89) ; 4.4％(4/90),0.0％(0/90)],but proportion of iodine excessive population in rural children [26.3％(79/300)] was significantly higher than proportion of iodine deficiency[5.6％(17/300)].ConclusionsThe natural environment of Harbin city is still in the iodinedeficient state.In addition to children in rural areas,the iodine intake and iodine nutrition level is basically appropriate; the risk of disease caused by iodine deficiency in adults,lactating and pregnant women is higher than by iodine excess,but the situation of children in rural is on the opposite.Therefore,we should strengthen the monitoring of different populations,and supplement iodine scientifically based on their need.

OBJECTIVETo study the effect of Qinghuang Powder (QHP) combined Chinese herbs for Pi-strengthening and Shen-reinforcing (CHPSSR) on hypoxia-inducible factor 1alpha (HIF-1alpha) in bone marrow mononuclear cells of myelodysplastic syndrome (MDS) patients.

METHODSChanges of HIF-1alpha in bone marrow mononuclear cells of MDS patients were detected in 25 MDS patients treated by QHP combined CHPSSR using flow cytometry. Meanwhile, 13 healthy subjects were recruited as the control group. Changes HIF-1alpha levels in various serial bone marrow mononuclear cells were detected.

RESULTS(1) Among the 25 patients in the treatment group, there were 19 patients effective and 6 patients ineffective, with the total effective rate being 76%. (2) Compared with before treatment, levels of peripheral blood WBC, Hb, PLT, and ANC significantly increased in the treatment group after treatment, showing statistical difference (P < 0.05, P < 0.01). (3) Compared with before treatment, the HIF-1alpha mean fluorescence intensity was enhanced in bone marrow lymphocytes, monocytes, granulocytes, and nucleated red blood cells of the treatment group after treatment (P < 0.05, P < 0.01). Compared with the control group, the HIF-1alpha mean fluorescence intensity was weakened in bone marrow lymphocytes, monocytes, and nucleated red blood cells of the treatment group before treatment; while it was obviously enhanced in granulocytes (P < 0.01). But after treatment the HIF-1alpha mean fluorescence intensity increased more in the granulocytes of the treatment group than in those of the control group (P < 0.01), but there was no statistical difference in bone marrow lymphocytes, monocytes, or nucleated red blood cells.

CONCLUSIONQHP combined CHPSSR could improve HIF-1alpha levels in bone marrow lymphocytes, monocytes, granulocytes, and nucleated red blood cells of MDS patients, thus improving Hb levels of MDS patients, and improving their anemia and correlated symptoms.

Objective To investigate the epiderniology of fungemia and provide evidence for clinical therapy.Methods A retro- spective survey was done with the 31 cases of fungemia in our hospital from August 2004 to November 2005.Results More than 80% of the patients suffered from two and more underlying diseases.Over a half of infections developed following placement of catheters.And 83.9% of the patients had a history of antimicrobial agents use before blood culture.The pathogens of 24 (77.4%) cases were associated with Candida spp.Only 3 strains were C.albicans.The mortality rate of candidemia was 45.8%.Different Candida species had different resistance rates to antifungal agents.Conclusions Fungemia patients often have serious underlying diseases.Most fungemia cases were candidemia caused by non-C.albicans.Some fungal pathogens are re- sistant to fluconazole and itraconazole.

OBJECTIVETo investigate the status of human papillomavirus ( HPV) infection and its genotypes in male patients in Zhenjiang area.

METHODSUsing PCR and reverse dot blot hybridization, we determined the genotypes of HPV DNA in 245 male patients at our Clinic of Dermatology and STD.

RESULTSThe total rate of HPV infection was 43.67% (107/245), and 18 subtypes were detected. Among the 107 HPV-positive cases, low-risk, high-risk, and combined high- and low-risk infections accounted for 39.25% (42/107), 38.32% (41/107), and 22.43% (24/107), respectively. The most notable low-risk HPV types were HPV6 and HPV11, and the most notable high-risk HPV types were HPV16, HPV52, and HPV58. The rates of single infection and multi-infection were 53.27% (57/107) and 46.73% (50/107), respectively. One case had the most types, infected with 8 genotypes. No statistically significant differences were observed in the total rate of HPV infection among different age groups (Χ2 = 7.999, P > 0.05).

CONCLUSIONThe dominant subtypes of HPV infection in male patients in Zhenjiang area were HPV6, HPV11, and HPV16. The most common subtypes were HPV6 and HPV11 in low-risk infection, and HPV16, HPV52, and HPV58 in high-risk infection.

Objective To investigate the differences of various two-stent techniques in vitro and virtual bench testing. Methods Stent implantation with classic crush, double kissing ( DK) crush and culotte stenting techniques were performed in the silicone simulation model of bifurcation vessels with various distal bifurcation angles. The whole processes were recorded by a micro-focus camera. Results Distal side branch (SB) re-crossing in classical crush technique left a significant gap without stent coverage near the carina in T type bifurcation model after final kissing balloon inflation (FKBI) . The gap was also noted in either classic crush with proximal SB re-crossing or DK crush with two times proximal SB re-crossing in T type bifurcation model. The size of the gap in DK crush technique was smaller than that of classic crush. In Y type bifurcation model, both DK crush and culotte stenting left no gap compared to T type bifurcation model. Two times proximal SB re-crossing in culotte stenting resulted in a new stent carina formation after FKBI. Conclusions Distal bifurcation angle was an anatomatic predictor of gap formation in two-stent technique. In T type bifurcation model, the size of gap in DK crush technique was smaller than that of classic crush. It was suggested to perform two times proximal SB re-crossing for DK crush technique and distal SB re-crossing for culotte stenting.

Aim The pharmacodynamics and mechanism of Kadsura heteroclita on the Alzheimers disease (AD) model mice were studied. Methods The Kunming mice were treated with D-galactose and AlCl 3(90 d)to make the AD animal model. The therapy groups were treated with HS 2 (po, 40 d) respectively since d51. The Morris water-maze test, the expressions of PS1, BACE, as well as the pathological observation of the hippocampus and cerebral cortex were carried out to evaluate the effect of HS 2 on the AD model mice. Resluts By oral administration with HS 2, the capacity of learning and memory of the AD model mice was improved. HS 2 can downregulate the expression of PS1, BACE and decrease the amount of senile plaque in their brains. Conclusion HS 2 can meliorate AD model mice's learning and memory deficiency as well as decrease the mRNA content of PS1, BACE and senile plaque in their brains.

AIM: This study was designed to investigate the effect of ginsenoside Rg1 on the amyloid ?-protein precursor (APP) and neprilysin (NEP)expression induced by lipopolysaccharide (LPS) in C6 cell line in order to discover effectual Alzheimer's disease (AD)-treated drugs. METHODS: MTT colorimetric analysis was used to measure the survival rate of C6 cultured with ginsenoside Rg1 at different concentrations (2 5, 5, 10 and 20 ?mol?L -1) and LPS (100 mg?L -1). The expression of APP and NEP mRNA was measured by RT-PCR. RESULTS: LPS decreased the survival rate of C6, furthermore, the increase in APP expression and the decrease in NEP expression were observed. On the other hand, the above alteration induced by LPS was reversed by ginsenoside Rg1. CONCLUSION: This study demonstrates that LPS can cause cell damage, the increase in APP expression and the decrease in NEP expression. Ginsenoside Rg1 can exert a neuroprotective action, protect C6 cells against LPS-induced injury via inhibiting APP expression and increasing NEP expression.

AIM: To investigate the inhibitory effect of TanshinoneⅡA on U251 glioma cell line and its mechanism. METHODS: MTT was used to measure the levels of the proliferation in U251 cultured with TanshinoneⅡA at different concentrations. The effects of TanshinoneⅡA on cell cycle of U251 were observed by FCM. The expression of proto-oncogene c-myc was measured by RT-PCR. RESULTS: The proliferation of U251 was obviously inhibited by TanshinoneⅡA in a dose dependent manner. The inhibitory rate came to the peak at (54 2?0 9)%, when cultured with TanshinoneⅡA at 0 10 g/L. The outcome of FCM showed that the proportion of G 0/G 1 phase cells was increased and the proportion of S phase cells was reduced obviously, when cultured with TanshinoneⅡA at 0 10 g/L for 3 days. The RT-PCR experiment showed that the expression of proto-oncogene c-myc was notably decreased, when the dose of TanshinoneⅡA was increased. CONCLUSION: TanshinoneⅡA inhibited the proliferation of U251 and the expression of proto-oncogene c-myc.
