Objective To compare the effects of every-other-day dose simvastatin administration with that of daily therapy of same dose.Methods This was a randomized,prospective,nonblinded clinical trial.The 186 patients with high low-density lipoproteim cholesterol(LDL-C) and/or high total cholesterol (TC),triglycerides (TG),low high-density lipoprotein cholesterol(HDL-C)was studied.All patients were randomized into two groups.The every-other-day do- sing group recerived 20mg of simvastatin in alternate-day and daily dosing group received 20mg of simvastatin every day.Before and after 6 weeks,12 weeks of treatment,serum lipoprotein,Live function tests and ereatine kinase con centra- tion and so on were drawn and bad-side effect were studies.Results The two groups significantly reduce LDL-C,TC, TG and a little increased HDL-C compared with baseline.No stalistically significant differences existed between the two groups in percentage in decrease in lipoprotain at 6 weeks,12 weeks compared with baseline.The bad-side effect in the two groups also had not a singnificant different.Conclusion The every-other-day dose of simvastatin have similar effi- cacious and safe to daily dosing in patients with hyperlipidemia and some cost savings.It can take a primary prevention to coronary heart disease in patients with relatively low-risk hyperlipidemia.

OBJECTIVETo investigate the effect of Liuwei Dihuang Soft Capsule(LDSC) and Ginkgo Leaf Tablet (GLT) on serum regulated upon activation, normal T cell expressed and secreted (RANTES) in the patients with diabetes mellitus type 2 (DM2).

METHODSForty patients with early stage DM2 were randomly assigned to two groups, 20 in each group. Based on the conventional treatment with hypoglycemic agents, patients in the treated group were treated with LDSC plus GLT additionally, and those in the placebo group with placebo for 6 months, respectively. The levels of serum RANTES, blood glucose, blood lipids and glycosylated hemoglobin, as well as micro-content of albumin in urine were measured before and after treatment.

RESULTSIn the treated group, the serum level of RANTES decreased significantly after treatment, and it was significantly lower as compared with that in the control group (P < 0.05).

CONCLUSIONSLDSC and GLT can decrease serum RANTES level in patients with DM2. They play a preventive and therapeutic role on diabetic complications by their anti-inflammatory effect.

Objective To observe the expression of Na+/I- symporter(NIS) in cultured lactating mammary cells with different levels of iodine and the effect of tumor necrosis factor-α(TNF-α). Methods Original generation of mouse lactating mammary cells cultured in vitro were divided into low iodine group Ⅰ (LI-Ⅰ), low iodine group Ⅱ (LI-Ⅱ), adequate iodine group(AI), high iodine group Ⅰ(HI-Ⅰ), and high iodine group Ⅱ(HI-Ⅱ). Cells were cultured in DEME/F12 culture medium for 24 h with different concentrations of iodine (0,5,50,3000 and 10 000 μg/L, respectively), and TNF-α( 10-2 mg/L) was added to some of cultured cells for 24 h. The expression of NIS mRNA of lactating mammary cells was determined by real-time quantitative PCR and the expression of NIS protein was detected by In-Cell Western. Results In iodine alone group, the expression of NIS mRNA in LI-Ⅰ group [ (64.66 ± 14.99) x 10-4] was higher than that of AI group[ (22.76 ± 7.36) × 10-4, P ＜ 0.01 ]; HI-I group[ (10.18 ±3.53) × 10-4] and HI-Ⅱ group[ (8.59 ± 2.89) × 10-4] were lower than that of AI group(all P ＜ .0.05); With increased iodine concentration, the expression of NIS mRNA decreased. The expression of NIS mRNA in LI-Ⅰ group [(2.72 ± 0.45) × 10-4], LI-Ⅱ group[ (2.69 ± 0.68) × 10-4] and AI group[(1.80 ± 0.67) × 10-4] with iodine plus TNF-o were all lower than that of LI-Ⅰ group, LI-Ⅱ group[ (29.82 ± 4.47 ) × 10-4], and AI group without TNF-α (all P ＜ 0.01). In iodine plus TNF-α, the expression of NIS mRNA in HI-Ⅰ group[(6.58 ± 2.87) × 10-4] and HI-Ⅱ[(7.04 ± 1.36) × 10-4] group were all higher than that of AI group(all P ＜ 0.05); With increased iodine deficiency or iodine excess, the expression of NIS mRNA increased. With increased iodine concentration, the expression of NIS protein decreased in iodine alone group. The expression of NIS protein in iodine plus TNF-α was all lower than that in iodine alone group. In iodine plus TNF-α, the expression of NIS protein increased in both iodine deficiency and iodine excess conditions. Conclusions Iodine may decrease the expression of NIS mRNA and protein of lactating mammary cells. The expression of NIS mRNA and protein of lactating mammary cells was inhibited by TNF-α under different levels of iodine.

ObjectiveTo study the morphological and functional changes of thyroid in lactating rats and their offspring in iodine deficiency and iodine excess animal models.MethodsOne hundred and twenty Wistar rats(30 males and 90 females) were selected.Based on their body weight,the 90 females were stratified and randomly divided into five groups( 18 in each group):low iodine group 1 and group 2(fed with low iodine feed and deionized water containing iodine of 0,5 μg/L) ; high iodine group 1,group 2 and control group(feed with normal diet and deionized water containing iodine of 3000,10 000,50 μg/L).After fed for 3 month,all female rats were mated with males in a ratio of 3 ∶ 1.After birth for 10 days,8 female rats and their offspring in each group were sacrificed.Changes of thyroid were observed by naked eyes.The thyroid weight was measured and pathological changes of thyroids were observed under light microscope.Results①Absolute and relative weight of lactating rats thyroid in low iodine group 1 and group 2 [ (92.02 ± 24.40 ),(77.11 ± 23.32 )mg,(0.509 ± 0.072),(0.384 ± 0.089) mg/kg] were much higher than that of control group[ (17.41 ± 9.25)mg,(0.102 ± 0.016)mg/kg,all P＜ 0.05].Absolute and relative weight of lactating rats thyroid in high iodine group 1 and group 2[(8.22 ± 0.41 ),(9.42 ±0.43)mg,(0.047 ± 0.006),(0.035 ± 0.005)mg/kg] were lower than that of control group(all P ＜ 0.05).Absolute and relative weight of lactating rats and their offspring thyroid was decreased with increase of iodide intake in the diet.②Thyroid enlargement of lactating rats in low iodine group 1 and group 2 was evident,but that of high iodine group 1 and group 2 was not.③Epithelial cell hyperplasia and smaller follicular cavity were observed in low iodine group 1 and group 2 under light microscope.Epithelial cell deformation and mostly flat were observed in high iodine group 1 and group 2.ConclusionsThyroid morphology is changed with iodide intake in the lactating rats and their offspring,and the changes are consistent between female rats and their newborns.

Objective To investigate the efficiency of levodopa in dopa responsive dystonia (DRD) patients and drugs safety in pregnancy cases confirmed by genetic detection.Methods The clinical characteristics of two patients were analyzed.Direct sequences were performed in guanosine triphosphate (GTP) cyclohydrolase Ⅰ (GCH1) gene and tyrosine hydroxylase (TH) gene mutation screening.Results Case 1 was a young man exhibiting writer's cramp and dystonia of lower legs with marked diurnal fluctuation.Writer's cramp could not be relieved by treatment of low dose levodopa/benserazide.After increasing dose,the symptom of writer's cramp appeared occasionally.Case 2 was a young woman who experienced gait disorder.The symptom disappeared completely by levodopa treatment.She used levodopa and benzhexol during pregnancy.By 38 gestational weeks,she gave birth to a healthy baby.Sequence analysis of GCH1 gene in case 1 revealed a mutation (c.230C ＞ G p.S77C) that is a novel pathogenic mutation.The confirmed mutation c.628delC (p.His210Thrfs* 5) found in case 2 had been reported previously.No mutations in TH gene were detected in two patients.Condnsions Most of DRD patients have dramatic response to levodopa,but patients exhibited writer' s cramp may respond to levodopa incompletely.The previous reports indicate that no adverse events have been reported in DRD pregnant women with the monotherapy of levodopa.

Objective To explore the role of the autoantibodies against ?_1 and ?_1-adrenergic receptor(?_1-receptor)in the development of hypertension with renal failure.Methods The epitopes of the second extracellular loop of ?_1-receptor(197-222) and ?_1-receptor(192-218) were synthesized and used respectively to screen sera autoantibodies in patients with hypertension and renal failure(n=61),hypertension without renal failure(n=60) and healthy blood donors(n=40,control) by ELISA.Results The positive rates of the autoantibodies against ?_1-receptor(62.3%)and ?_1 receptor(50.8%) in patients with hypertension with renal failure were higher than those of patients with hypertension without renal failure(13.3% and10.0%)(P

Objective To evaluate the melancholia incidence in the convalescence period of cerebral hemorrhage and its correlated factors.Methods Ninety-eight cerebral hemorrhage patients in the convalescence period were involved in this study.Melancholia was assessed by Hamilton depression scale (HAMD),neural functional deficiency was assessed by the national institute of health stroke scale (NIHSS),cognitive function deficiency was assessed by the Montreal cognitive assessment (MoCA) and neural functional deficiency recovery was assessed by modified Rankin scale (mRS).Hemorrhagic site and blood quantity were detected with CT.The blood flow of middle cerebral artery (MCA),anterior cerebral artery (ACA),posterior cerebral artery (PCA) was detected by TCD.Results The melancholia incidence in the convalescence period was 51.0％(50/98),34.0％(17/50) in males and 68.8％(33/48) in females,there was significant difference between the two (P ＜ 0.05 ).The scores of NIHSS and mRS had significantly positive correlation with HAMD (P ＜ 0.05 ),and had significantly negative correlation with MoCA (P ＜ 0.05 ).When the hemorrhagic site was in frontal lobe and blood quantity was 20-40 ml,the melancholia incidence was increased [76.2％ (16/21),62.5％ (25/40)].The average blood velocity of MCA,ACA and PCA in melancholia patients was significantly slower than that without melancholia patients,while resistance index was significantly higher in melancholia patients (P ＜ 0.05).Conclusions Melancholia incidence in the convalescence period of cerebral hemorrhage has positive correlation with sex,NIHSS,MoCA,hemorrhagic site and blood quantity.The average cerebral blood flow in the melancholia patients is significantly slower and resistance index is significantly higher.

ObjectiveTo observe the influence of iodine on mRNA expression of iodide transporter (NIS),insulin-like growth factor Ⅰ (IGF- Ⅰ ) and transforming growth factor beta(TGF-β) in thyroid and mammary glands of lactating rats and to explore the role of NIS,IGF- Ⅰ and TGF-β mRNA in iodine uptake in thyroid and mammary glands of lactating rats.MethodsOne hundred and one Wistar rats(80 female and 21 male),weighting 8 - 100 g were selected.These female rats were randomly divided into five groups according to their body weight:control group(NI,normal feed,drank deionized water containing iodine 50 μg/L) ; low iodine group 1 and 2(LI-1,LI-2,low iodine feed,drank deionized water containing iodine 0 and 5 μg/L,respectively); high iodine group 1 and 2(HI-1,HI-2,normal feed,drank deionized water containing iodine 3000 and 10 000 μg/L,respectively),16 rats in each group.After feeding for 3 months,the female and male rates were mated 3:1.The female rats in each group were sacrificed at the fifth and tenth day after postpartum.Thyroid and mammary glands were taken.The mRNA levels of NIS,IGF- Ⅰ and TGF-β in thyroid and mammary glands of lactating rats were determined by real time quantitative PCR.ResultsThe fifth days after postartum,NIS,IGF- Ⅰ and TGF-β mRNA expression levels of thyroid and lactating mammary glands were different between groups,and the differences were statistically significant ( NIS:F =631.46,64.91,all P ＜ 0.01 ; IGF- Ⅰ:F =11.45,6.56,all P ＜ 0.01 ; TGF-β:F =291.83,304.53,all P ＜ 0.01).Compared with control group [NIS:0.0066 ± 0.0023, (0.1481 ± 0.0711 ) × 10-2; IGF- Ⅰ:0.0419 ± 0.0062,0.0542 ± 0.0044; TGF-β:0.1416 ± 0.0277,0.1670 ± 0.0499],regardless of thyroid or mammary gland,the NIS,IGF- Ⅰ and TGF-β mRNA expression of LI-1 [NIS:0.0447 ± 0.0110,(0.3030 ± 0.1831) × 10-2;IGF- Ⅰ:0.0662 ± 0.0078,0.0902 ± 0.008; IGF- Ⅰ:0.5514 ± 0.0508,0.6942 ± 0.0367],LI-2[NIS:0.0317 ±0.0081,(0.3017 ± 0.1601) × 10-2; IGF-I:0.0645 ± 0.0054,0.0894 ± 0.0093; TGF-β:0.5292 ± 0.0332,0.6704 ± 0.0277 ] was significantly increased (all P ＜ 0.01 ); the NIS mRNA expression of HI-1 [0.0043 ± 0.0011,(0.1233 ± 0.0954) × 10-2],HI-2[0.0037 ± 0.0017,(0.1058 ± 0.0854) × 10-2] was decreased(all P ＜ 0.05),while the expression of IGF-Ⅰ mRNA [0.0521 ± 0.0910,0.0715 ± 0.0026; 0.0516 ± 0.0078,0.0697 ± 0.0038] and TGF-β mRNA [0.2087 ± 0.0425,0.2361 ± 0.0425; 0.1971 ± 0.0237,0.2257 ± 0.0752 ] was increased (all P ＜ 0.05 ).The tenth days after postpartum,the mRNA expression levels of NIS,IGF- Ⅰ and TGF-β of thyroid and lactating mammary gland in rats were different between groups,and the differences were statistically significant (NIS:F =103.55,116.32,all P ＜ 0.01; IGF-Ⅰ:F =67.67,11.98,all P ＜ 0.01; TGF-β:F =74.30,381.30,all P ＜0.01 ).Compared with the control group[NIS:0.0069 ± 0.0011,(0.1337 ± 0.0599) × 10-2; IGF-Ⅰ:0.0390 ±0.0071,0.0534 ± 0.0056; TGF-β:0.1351 ± 0.0336,0.1534 ± 0.0320],the mRNA expression levels of NIS,IGF- Ⅰ and TGF-β of LI-1 [ NIS:0.0432 ± 0.0165,(0.2962 ± 0.0985 ) × 10-2; IGF- Ⅰ:0.0643 ± 0.0088,0.0873 ± 0.0055 ; TGF-β:0.5042 ± 0.0912,0.6408 ± 0.0420],LI-2[NIS:0.0287 ± 0.0111,(0.2873 ± 0.0862) × 10-2; IGF- Ⅰ:0.0621 ± 0.0094,0.0862 ± 0.0038; TGF-β:0.4893 ± 0.0504,0.6372 ± 0.0389] were significantly increased(all P ＜ 0.01 ); the NIS mRNA levels of HI-1 [ 0.0042 ± 0.0029,(0.1006 ± 0.0909) × 10-2],HI-2[0.0035 ± 0.0020,(0.0890 ± 0.0119) × 10-2] were decreased(all P＜ 0.05),while the expression of IGF-Ⅰ mRNA[0.0516 ± 0.0078,0.0668 ± 0.0071; 0.0508 ± 0.0089,0.0621 ± 0.0064] and TGF-β mRNA[0.2007 ± 0.0546,0.2175 ± 0.0370;0.1959 ± 0.0393,0.2097 ± 0.0425] were increased(all P ＜ 0.05 ).In thyroid and mammary glands,the comparisons of NIS,IGF,TGF-β mRNA expression of the fifth and tenth day after postartum,between each group were not statistically significant(all P ＜ 0.05).ConclusionsThere are regulatory mechanisms of thyroid and mammary glands of lactating rats in response to low or high iodine conditions.In low iodine,the expressions of NIS,IGF- Ⅰ and TGF-β mRNA in thyroid and mammary glands increase and iodide uptake ability is enhanced to meet the body needs.In high iodine,the expression of NIS mRNA decreases in thyroid and mammary glands.Due to the reduced ability of iodine uptake,iodine intake is reduced,thereby reducing the hazards of high iodine in filial rats.
