Background Rosuvastatin has been unanimously recognized as an very highly efficacious statin. Rosuvastatin significantly reduced microalbuminuria and its powerful anti-inflammatory effect confer anti-atherosclerosis in patients with essential hypertension. Objective To study the influence of rosuvastatin on microalbuminuria and arteriosclerosis plaque of carotid and coronary arteries in hypertensive patients. Methods Seventy-six hypertensive patients were randomly to receive conventional anti-hypertensive drugs (amlodipine 5 mg/d and telmisartan 80 mg/d,n=37) or rosuvastatin (10 mg QN) on the top of conventional anti-hypertensive drugs (n=39). The blood pressure,levels of microalbuminuria,echocardiography and helical computerized tomography were examined before and 8 months after treatment in all patients. Results After 8 months of treatment,SBP and DBP were decreased in both group [conventional treatment from (166.3?11.2)/(92.4?8.2) to (133.6?9.8)/(85.5?6.1)mmHg,combined group from (165.6?10.5)/(91.5?6.7) to (128.1?9.2)/(81.1?5.9)mmHg]. Combined treatment significantly reduced the levels of microalbuminuria [(31.6?21.8) to (23.2?19.8)mg/g,P

Objecfive To investigate the role of serum Insulin-like growth factor(IGF)-1,insulinlike growth factor-binding potein(IGFBP)-3 in children with Henoch-Schonlein purpura(HSP).Methods The serum concentration of IGF-1,1GFBP-3 was measured by enzyme-linked immunosorbent assay(ELISA)method in 45 acute SHP patients,40 recoverv patients and 30 healthy controls.Results The serum levels of IGF-1 [(452±183)μg/L],IGFBP-3 [(13 897±3124)μg/L] and C-reactive protein(CRP)[(20±8)mg/L]in acute phase were significantly higher than those in healthy controls(P<0.0 1)and higher than those during recovery period.The serum level of IGF-1,IGFBP-3 for the HSP patients dropped back slowly and their levels during recovery period were the same as those in healthy controls(P>0.05).The serum levels of IGF-1[(621±253)μg/L] and IGFBP-3[(18 763±3173)μg/L] were higher in the renal damage group than in the non-renal damage group(P<0.01).and the same in patients with gastrointestinal symptoms group as in patients without gastrointestinal symptoms group(P>0.05).whereas the serum level of CRP was not significantly different(P>0.05).The serum levels of IGF-1,IGFBP-3 showed positive correlation with the level of CRP(r=0.624,0.672,P<0.01).Conclusion The IGF-1 and IGFBP-3 may play an important role in the pathological mechanism of HSP.The level of IGF-1 may be used as an indicator for HSP disease activity and progression.IGF-1 mav have a close relation with the damageof renaJ system in HSP.

OBJECTIVETo investigate the clinical outcomes of the posterior C1,2 screw-rod combined with C2 unilateral translaminar screw and contralateral pedicle screw fixation and autogenous bicortical iliac crest graft fusion in treating upper cervical instability with vertebral artery variations.

METHODSFrom June 2008 to December 2012, the clinical data of 12 patients with upper cervical instability underwent C1 lateral mass screws-C2 unilateral laminar and contralateral pedicle screws fixation combined with autogenous bicortical iliac crest graft fusion were analyzed retrospectively. There were 8 males and 4 females with a mean age of 47.5 years (ranged, 16 to 77 years). Patients suffered from occipitocervical activity limitation of motion with pain or not, VAS was 0-7 points with an average of (3.50 +/- 2.71) points. Unilateral vertebral artery hypoplasia was demonstrated by vertebral arteriography (VAG) or CTA in all patients. Cervical X-ray and CT scans were done within 7 days after surgery in order to confirm internal fixation position. Internal fixation loosening and breakage, reduction losing, bone fusion ratio were observed during follow-up.

RESULTSNo nerves and vertebral artery injuries occurred during operation. Cervical pain obviously decreased and VAS was (0.92 +/- 0.90) points. Cervical alignment of 12 patients had well-recovered by X-ray while Atlantoaxial ventral lamina cortex of 1 case was encroached by CT scan without neurological symptom. All patients were followed up for 6 months to 3 years, no internal fixation loosening and breakage, reduction losing were found. All patients obtained bone fusion in 6-12 months after operation.

CONCLUSIONPosterior C1 lateral mass screws-C2 unilateral laminar and contralateral pedicle screws fixation combined with autogenous bicortical iliac crest graft fusion can achieve biomechanical stability and raise the successful rate of bone fusion, while avoiding the risk of vertebral artery injury and overcoming the insufficient of bone fusion during bilateral laminar screws placement as well. Posterior C1 lateral mass screws fixation is a safe and effective additional method in treating upper cervical instability with vertebral artery variations.

Data were collected through questionnaire from 505 women enrolled during early pregnancy.Based on soy intake frequency,the subjects were divided into three groups:frequent (three or more times per week),conventional ( more than twice per month but less than three times per week),and occasional ( two or fewer times per month).Serum TSH and FT4 were measured by chemiluminescence immunoassay.The urinary concentrations of two primary isoflavones (daidzein and genistein) and creatinine were further assessed in 95 subjects from the three groups.The percentages of frequent,conventional,and occasional consumers were 18.6％,62.6％,and 18.8％,respectively.No difference was found in age,medical records,family history of thyroid diseases,serum FT4,TSH,and prevalence of thyroid dysfunctions among three groups. Both urinary daidzein and genistein levels were significantly higher in the frequent consumers compared with the other two groups.No correlations were found between urinary isoflavone levels and serum FT4 or TSH.These findings suggest that dietary soy consumption during early pregnancy seems not to be associated with the development of thyroid dysfunction.

OBJECTIVETo investigate clinical features of the traumatic cervical disc herniation and through retrospective analysis 62 cases of traumatic cervical disc herniation.

METHODSAmong 62 patients with traumatic cervical disc herniation, 46 patients were male and 16 patients were female, with an average ages of 36.4 years. According to the clinical manifestation, there were 30 cases of symmetrical limb palsy, 19 cases of upper motor palsy serious than lower, 13 cases of unilateral palsy and contralateral disorder of algesthesia and thermesthesia. There were 58 patients treated with operation and 4 patients treated with conservative method.

RESULTSAll of the incisions were with primary healing. Twenty-four patients recovered to normal, and other 34 cases improved obviously and the duration of follow-up ranged from 6 to 28 months. The average time was 11 months. JOA scores increased from preoperative 5.6 to postoperative 12.7.

CONCLUSIONOperative treatment is effective for different types of the traumatic cervical disc herniation.

OBJECTIVETo investigate the relationship between chronic periodontitis and the genetic polymorphisms of vitamin D receptor gene and estrogen receptor gene.

METHODSClinical parameters including probing depth, clinical attachment loss, sulcus bleeding index and tooth movement were measured by fluoride probe. Genomic DNA from peripheral venous blood was extracted with saturant sodium chloride, and PCR-restriction fragment length polymorphism was applied to examine the Apa I, Bsm I, Taq I polymorphisms of the vitamin D receptor genes and the Xba I and Pvu II polymorphisms of the estrogen receptor genes. The results were analyzed by Z-score test and mean square analysis.

RESULTSForty-three point four percent of chronic periodontitis patients took vitamin D receptor BB genotype, the rate in healthy controls was 30.0%. 39.6% of chronic periodontitis patients took estrogen receptor XX genotype, the rate in healthy controls was 20.0%. The people who took BBXX genotype had the worst periodontal conditions among all chronic periodontitis patients.

CONCLUSIONSVitamin D receptor allele B and estrogen receptor allele X are susceptible alleles for chronic periodontitis. The synergistic effects of the two receptor susceptible alleles may promote chronic periodontitis.
