Objective To investigate the effects of repeated administrations of 6% hydroxyethy] starch (HES) 130/0.4 or 7.5 % NaCl (NS) on brain water content (BWC) after experimental intracerebral hemorrhage (ICH) in rats.Methods One hundred and sixty-seven male SD mrs weighing 260-300 g were randomly divided into 4 groups: group Ⅰ sham operation (S) (n = 20) ;group Ⅱ ICH (n = 38) ;group Ⅲ NS + ICH (n = 55) and group Ⅳ HES + 1CH (n = 54). The animals were anesthetized with intraperitoneal 10% chloral hydrate 400 mg/kg. Experimental ICH was produced by injection of fresh autologous blood 50 μl into right caudate nucleus. In group NS (group Ⅲ) 7.5% NaCl 5 ml/kg and in group HES (group Ⅳ) 6% HES 30 ml/kg were injected at 2, 24, 48 and 72 h after ICH. In group S and ICH (group Ⅰ and Ⅱ) 5 animals were killed at 2, 24, 48 and 72 h after ICH, while in group Ⅲ (NS) and Ⅳ (HES) 5 animals were killed at 2, 24, 48 and 72 h after ICH, immediately before and after NS/HES infusion for determination of ipsilateral and contralateral cerebral cortex and basal ganglion, weight and W/D weight ratio. Rosenberger behavior scores and survival rates were also recorded. Results In group Ⅲ (NS + ICH) and Ⅳ (HES + ICH) the water content of ipsilateral cerebral cortex and basal ganglion was significantly lower than in group Ⅱ (ICH). Rosenberger behavior scores at 24 h and 48 h after ICH were significantly lower in group NS and HES than in group Ⅱ (ICH) . The survival rates at 24, 48 and 72 h after ICH were significandy lower in group Ⅱ than in group NS and HES, especially at 72 h in group HES. Conclusion Repeated administrations of 6% HES 130/0.4 or 7.5% NaCl can ameliorate brain edema after ICH.

Objective To observe the effects of repeated dosing of 6% hydroxyethyl starch (130/0.4) or 7.5% sodium chloride on brain edema after experimental intracerebral hemorrhage (ICH) in rats. Methods 167 male SD rats were divided into four groups randomly: Sham operation group (S, n=20), ICH control group (M, n=38), 7.5% sodium chloride group (N, n=55) and 6% hydroxyethyl starch group (H, n=54). The model of the ICH was established with stereotactically infusing 50 μl of the autologous femoral artery blood into the right caudate nucleus. group N and group H received 7.5% sodium chloride 5 ml/kg and 6% hydroxyethyl starch 30 ml/kg at 2 h, 24 h, 48 h and 72 h after operation respectively. The tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), superoxide dismutase (SOD) and malondialdehyde (MDA) in the tissue around the hemorrhage were measured at different time point. Results The IL-6 in group N was significantly more than that in group M at 24 h and 72 h after infusion (P<0.05), and the TNF-α in group H was less than that in group M at 24 h and 48 h after infusion (P<0.05). The SOD in group M decreased to the bottom at 48 h and 72h after ICH. SOD in group N and group H at 24 h, 48 h and 72 h after infusion was both significant more than that in group M (P<0.05). MDA in group H at 72 h after infusion was less than that in group M (P<0.05). Conclusion Repeated infusion of 6% hydroxyethyl starch (130/0.4) or 7.5% sodium chloride can decrease inflammatory response of brain tissue after ICH, which may protect brain from oxidative damage.

Objective To study the variation of serum thyroid hormones in each trimester of pregnancy and their relationship with thyroid peroxidase antibody(TPOAb).Methods Three-hundred and seventy-seven pregnant women in different trimesters were enrolled,the serum TSH,FT3,FT4,TT3,TT4,and TPOAb were determined by ICMA assay.Results Serun TSH in normal pregnant group was gradually increased as the pregnant trimester grew up ( all P＜0.05 ).The median of TSH in positive TPOAb group was higher than that of negative TPOAb group( P＜0.05 ).The prevalences of both clinical and subclinical hypothyroidism in positive TPOAb group were also higher than those in negative TPOAb group( all P＜0.05 ).The prevalences of subclinical hypothyroidism were 23.61％ and 18.04％,while those of clinical hypothyroidism were 0.27％ and 5.84％ by using TT4 and FT4 determination,respectively( P＜0.05 ).Conclusions More attention should be paid to the difference between FT4 and TT4 in hypothyroidism diagnosis during both second and third trimesters of pregnancy.Establishment of normal thyroid hormoues cut-off points in each trimester of pregnancy and screening for TPOAb is necessary.

Objective To explore the association of serum uric acid (UA) with metabolic syndrome (MS) and its components.Methods A total of 1 512 inhabitants aged 20 years old and above in Zhaiji community of Guiyang urban areas were investigated from November 2009 to February 2010 by adopting stratified cluster sampling method (634 males and 878 females).All subjects were asked to fulfill the questionnaires and to measure the height,weight,waist circumstance (WC),and blood pressure ; and to undertake oral glucose tolerance test.Venous blood samples were drawn to measure UA,fasting plasma glucose,2 h postprandial plasma glucose,triglyceride (TG),total cholesterol,high density lipoprotein cholesterol,low density lipoprotein cholesterol,and fasting insulin.Results (1) Age,body mass index (BMI),WC,TG,and blood pressure,and homeostasis model assessment of insulin resistance (HOMA-IR) increased with UA (all P＜0.05).(2) UA was positively associated with the risk of MS (P＜ 0.05).After adjusting for age,sex,BMI,waist-to-hip ratio (WHR),and HOMA-IR,the risk of MS in individuals with the highest uric acid quartiles was significantly increased compared to those with the lowest quartile (OR =2.86,95 ％ CI 1.70-4.84,P＜0.05),and this finding was especially evident in females (OR=2.80,95％ CI 1.51-5.17,P＜0.05).(3) UA was strongly related to WC (OR =1.76,95％ CI0.95-3.27,P＜0.05),blood pressure (OR =1.66,95 ％ CI 1.13-2.43,P＜0.05),and TG (OR =2.80,95％ CI 1.97-3.96,P＜0.05) after adjustment for age,sex,BMI,WHR,and HOMA-IR.Conclusion The prevalence of MS increased with UA.Higher UA level may be an independent risk factor for MS.

Objective To investigate the level of soluble interleukin 7 receptor (sIL-7R) in serum of lupus nephritis(LN)patients and evaluate its clinical significance. Methods sIL-7R level in serum of LN patients and healthy controls were measured by ELISA , while total 24 hours urinary protein and complement C3 of LN patients were measured by BN ProSpec. The level of sIL-7R correlation with SLEDAI, total 24 hours urinary protein and complement C3 were analyzed respectively. Results The levelof sIL-7R was higher in serum of LN patients than healthy controls (P < 0.01). Moreover, its expression in serum was increased in LN patients in active stage than in LN patients in stable stage (P < 0.05). The level of sIL-7R was positively assosicated with SLEDAI, total 24 hours urinary protein(P < 0.01, P < 0.05) and negatively with complement C3 (P < 0.05). Conclusion The level of sIL-7R is upregulated in serum in LN patients and correlated with disease activity and progression, so it may be expected to become a potential marker of disease in prediction.

Objective To investigate the effects of curcumin on mRNA expression of cytokines related to Toll-like receptor (TLR) 4 signaling in THP-1 cells.Methods After pretreatment with different concentrations (50,25,12.5 mg/L) of curcumin or dexamethasone for 12 hours,THP-1 cells were stimulated by lipopolysaccharide (LPS.1 mg/L) for 4 hours followed by the collection of cells.Then total RNA was isolated from these cells and subjected to reverse transcription-polymerase chain reaction (RT-PCR) for the detection of mRNA expression of tumor necrosis factor receptor-associated factor 6 (TRAF6),interleukin-1 receptorassociated kinase (IRAK1) and nuclear factor (NF)-κB.THP-1 cells without pretreatment or stimulation served as negative control,and those only stimulated with LPS served as LPS group.Results After stimulation with LPS (1 mg/L) for 4 hours,the mRNA expressions of TRAF6,IRAK1 and NF-κB were significantly upregulated in THP-1 cells compared with negative control cells (f=38.69,39.13,23.99,all P<0.01).Curcumin of 50 mg/L and 25 mg/L significantly inhibited the mRNA expressions of TRAF6.IRAK 1 and NF-κB upregulated by LPS with an inhibition rate of more than 50% (all P<0.0 1).Conclusions Certain concentrations of curcumin can inhibit the mRNA expressions of TRAF6.IRAK1 and NF-κB.which demonstrates the regulatory effect of curcumin on the mRNA expressions of TLR4 signaling pathway-associated cytokines.
