Objective To investigate the consumption status of iodized salt and iodine nutrition status of Tianjin residents,and to provide a scientific basis for iodine supplementation.Methods Sampling methods:① Salt iodine:According to The National Project of Surveillance on IDD,the iodine in salt samples from 18 Tianjin districts (counties) was tested between 2002 to 2011.②Iodine nutritional status of children:Investigation of iodine nutritional status of children was conducted four times in 2002,2005,2009 and 2011.In 2002 and 2005,two primary schools were selected in each district.By age,gender parity principle,40 subjects aged from 8 to 10 in each school were randomly selected to perform thyroid examination and 20 of them were selected to collect urine samples for determination of urinary iodine.In 2009,according to their sub-area positions in the north,the south,the east,the west and the center of each district,5 primary schools were selected in each town (if there were less than five towns in the district,all towns had been selected).Twenty subjects aged from 8 to 10 in each school were selected to collect urine samples for determination of urinary iodine.In 2011,probability sampling method (PPS) was used to select 30 primary schools,and then 40 children aged from 8 to 10 were randomly selected in each school to examine thyroids.At the same time,urine samples from 12 children of the 40 selected children were tested.③Iodine nutritional status of women of childbearing age:In 2007,2008 and 2010,150,50 and 60 women of childbearing age were selected in Hangu District,urine samples of them were collected for determination of urinary iodine.④Iodine nutritional status of pregnant and lactating women:In 2011,3 towns around each primary school were selected.Five pregnant and five lactating women were selected in each town,urine samples of them were collected for determination of urinary iodine.Test methods:①Salt iodine was tested by direct titration,while Sichuan salt and other reinforced edible salt by arbitration determination based on the General Test Method in Salt Industry-Determination of Iodide Ion (GB/T 13025.7-1999).②Thyroid was tested by B-type-ultrasound and judged according to Diagnostic Criterion of Endemic Goiter (WS 276-2007).③Urinary iodine was tested by the Method for Determination of Iodine in Urine by As3+-Ce4+ Catalytic Spectrophotometry (WS/T 107-2006).Results From 2002 to 2011,the consumption rate of qualified iodized salt,the rate of qualified iodized salt,the coverage rate of iodized salt,the rate of non-iodinated salt was 92.7％(43 489/46 926),97.4％(43 489/44 694),95.1％ (44 694/46 926) and 4.8％(2273/46 926),respectively.The median salt iodine was in the range of 29.2-36.7 mg/kg.Children's urinary iodine was monitored 4 times,the median urinary iodine was 228.0,221.5,191.8; and 194.7 μg/L,respectively.Children goiter rates were 2.1％(27/1258),1.6％(19/1186) and 2.1％(26/1219) of the 3 times monitored.The median urinary iodine in pregnant and lactating women was 145.2 and 136.0 μg/L.The median urinary iodine in women of childbearing age was 130.7,196.1 and 229.5 μg/L,which increased with the increase of coverage of iodized salt.Conclusions The iodine nutrition of Tianjin residents,women of childbearing age and lactating women are at appropriate level.The iodine nutrition of pregnant women is lower than appropriate level.Recommended salt iodine level in our city is 30 mg/kg,or 25 mg/kg for ordinary residents,and 30 mg/kg for pregnant women.

Objective To investigate the prevalence of adult osteofluomsis in the endemic fluomsis areas in Tianjin and to provide scientific foundation for endemic fluorosis.Methods Stratified sampling in 55 villages were selected in 3 areas with slight,moderate and severe fluorosis regions in Tianjin from April to June in 2008.Water fluorine were tested and clinical osteofluorosis examinations were conducted to the population aging 16 and above in the villages.Tweenty villages were selected randomly in the slight,moderate and severe fluorosis regions.X-ray osteofluorosis examination were conducted to patients and suspected patients in these 20 villages.Results The geometric mean fluoride content in the water for the 3 areas were 1.35 mg/L,3.44 mg/L,5.49 mg/L,respectively.The prevalence of osteofluorosis were 36.7%(44/120),20.6%(33/160),39.4%(43/109),respectively.The prevalence of osteofluorosis Was increased gradually(r=0.534,P<0.01)and the symptoms and signs of the disease were more serious(H=84.813,P<0.01).The prevalence of X-ray diagnosis Was increased gradually(r=0.990,P<0.01)and signs of the disease were more severe(H=25.169,P<0.01)with an increase in age.There was no statistical significance of prevalence rate of osteofluorosis between males and females,regardless if it Was a clinical diagnosis(X2=0.343,P>0.05)or an X-ray diagnosis(X2=3.532,P>0.05).Conclusions Adult osteofluorosis to a certain extent is still prevalent in the fluorosis areas in Tianjin.Endemic fluorosis is still rampant.Improving water in fulorosis areas should be mandatory.

This study aimed to investigate the effects of concentration, intestinal section and borneol on the intestinal absorption of salvianolic acids. The experiment not only studied the intestinal absorption properties of three concentrations of rosmarinic acid, salvianolic acid B and salvianolic acid A at duodenum, jejunum and ileum, but also of salvianolic acids compatible with borneol at different concentrations using single-pass intestinal perfusion model in rat with phenol red as the marker. The results showed that salvianolic acids was stable under weak-acid condition and affected by metabolism enzyme; The Peff and Ka significantly different among three concentrations of rosmarinic acid and salvianolic acid B, whose intestinal absorption were saturated in high concentration, suggesting that the transport mechanisms of rosmarinic acid and salvianolic acid B were similar to active transport or facilitated diffusion; However, there was inconspicuousness in the Peff and Ka of salvianolic acid A at different concentrations, whose absorption was not saturated in high concentration, indicating that the transport mechanisms of salvianolic acid A was passive diffusion; The Peff and Ka in the ileum obviously higher than those in the duodenum and jejunum, namely the ileum was the best absorption section; When concentration of borneol increased, the enhancing effect of intestinal absorption of salvianolic acids increased, but significantly decreased when borneol increased to some degree. The enhancing effect of medium borneol concentration was the optimum. This implied that borneol can enhance the intestinal absorption of salvianolic acids, and the capacity of enhancing effect was influenced by the concentration of borneol.

OBJECTIVETo investigate the relationship between allergic rhinitis (AR) and asthma as well as the mechanisms related with it.

METHODSSixty healthy rats were randomly divided into AR group and control group. AR model was established by intraperitoneal injection of ovalbumin (OVA) and nasal challenge with OVA. Nasal mucosa and lung tissue from both groups were stained with hematoxylin-eosin (HE), alcian-blue and periodic acid-schiff (AB-PAS), respectively. At the same time, the lung tissue was studied by transmission electron microscopy (TEM). Enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry were used to examine the level of interleukin-4 (IL-4) in bronchial alveolus lavage fluid (BALF) and the expression of intercellular adhesion molecule-1 (ICAM-1) and MUC5AC in nasal and lung tissue, respectively.

RESULTSInfiltration of inflammatory cells in nasal mucosa and lung tissue of AR model in rat was evident. Cilia destruction of bronchial epithelial cells of AR model was found. The level of IL4 in BALF of AR group (58.10 +/- 7.92) pg/ml was significant higher compared with that in control group (24.66 +/- 2.07) pg/ml. The expression of ICAM-1 (0.66 +/- 0.24) and MUC5AC (0.71 +/- 0.10) in lung tissue were both significantly higher than that in control group (0.23 +/- 0.02, 0.29 +/- 0.03).

CONCLUSIONSAllergic inflammation in nasal mucosa not only leads to changes in both histopathology and immunology, but also initiates the inflammation in lower respiratory tract mainly causing the change of cytokines and mucin.

Objective Diclofeanc as probe drug to investigate the influence of Shenkang injection on the activity of CYP2C9 enzyme in rats.Methods A total of 24 SD male rats were randomly divided into control group (0.9％ NaCl),low dose (6.7 mL · kg-1),middle dose (13.3 mL· kg-1),high dose (26.6 mL · kg-1) Shenkang injection group,each group 6 rats.The relevant injection was administered by intraperitoneal injection,twice a day for 7 d.On the eighth day before collected the blood plasma samples each group were given relevant injection and all rats were injected with diclofenac (15 mg · kg-1,iv) 1 h after last administration.The orbital blood samples were collected before and 5,15,30,45 min and 1,1.5,2,3,4,6,8,10,12,24 h after diclofenac administration through femoral venous.A sensitive high-performance liquid chromatography method was established to characterize and validate for the determination of plasma concentration of diclofenac and 4'-hydroxy-diclofenac in rats.Pharmacokinetic parameters were calculated with WinNolin 6.1 pharmacokinetic software.Results The area under the concen-tration-time curve (AUC0-24 h) of diclofenac in control group,low,middle and high-dose Shenkang injection group were (21.12±2.88),(25.13 ±8.13),(31.11 ± 11.19),(32.32 ±6.18) mg · h · L-1(P ＞0.05).The AUC0→24h of 4'-hydroxy-diclofenac were (9.79 ±1.12),(7.84 ±2.67),(9.97 ±3.85),(10.39 ±3.38)mg · h · L-1 (P＞0.05).The t1/2 of diclofenac in control group,low,middle and high-dose Shenkang injection group were (6.21 ± 1.78),(7.46 ±2.20),(6.40 ± 1.50),(6.13 ±2.19) h(P ＞0.05).The t1/2 of 4'-hydroxy-diclofenac in control group,low,middle and high-dose Shenkang injection group were (11.53 ±4.31),(30.85 ± 10.52),(23.29 ± 13.09),(22.53 ± 10.95)h(P ＞0.05).There was no statistical significant difference in other pharmacokinetic parameters (P ＞ 0.05).Conclusion Consecutive administration of Shenkang injection may not have an effect on the pharmacokinetic of diclofenac and 4'-hydroxy-diclofenac of typical probe substrates of CYP2C9 in rats.The present study would provide some reference on Shenkang injection have no influence on CYP2C9.

OBJECTIVETo observe the intervention effect of Leihong Granule (LG) in in-stent restenosis (ISR) after endovascular therapy for lower extremity arterial occlusive diseases (LEAOD).

METHODSRecruited 80 LEAOD patients who successfully underwent endovascular therapy (balloon dilation and stent implantation) were randomly assigned to two groups, the control group and the LG group, 40 in each group. Patients in the control group received basic treatment, while those in the LG group additionally took LG for 3 months. Plasma levels of IL-10, IL-18, CRP, and the intima-media thickness (IMT) of lower extremity artery were observed in the two groups between and after treatment. The rate of stent patency, ABI, intermittent claudication, rest pain, and the incidence of amputation the two groups were recorded and observed in the two groups.

RESULTSIn the control group, serum levels of IL-10, IL-18, CRP, and IMT were significantly higher one month after surgery than before surgery (P < 0.05). There was no significant difference in serum levels of IL-10, IL-18, CRP, or IMT between the two groups before surgery (P > 0.05). These indices were obviously lower in the LG group than in the control group after surgery (P < 0.05). Compared with the control group, the incidence rates of intermittent claudication and the rest pain at 6 months and 12 months after surgery significantly decreased (P < 0.05). The stent patency rate at 6 months and 12 months after surgery, and ABI were significantly higher than those of the control group (P < 0.05). There was no statistical difference in the amputation rate between the two groups (P > 0.05).

CONCLUSIONLG might effectively improve ischemic symptoms of affected limbs possibly through lowering the ISR rate after endovascular therapy for LEAOD through preventing immunosuppressive actions.
