Objective To study the curative efficacy of different doses of atorvastatin combined with fenofibrate in treatment of mixed type hyperlipidemia and its effects on blood lipid and prognosis.Methods 120 patients of mixed type hyperlipidemia who received therapy were selected as research subjects.According to random number table,the patients were divided into A group (n=60) and B group (n=60).The two groups were treated with atorvastatin and fenofibrate,the dose of atorvastatin in A group was 10mg,which in B group was 20mg,fenofibrate dose was 200mg.After 4 weeks of treatment,the therapeutic effect was compared.Results After treatment,the blood lipids of the two groups were improved(P<0.05),but total cholesterol (TC),triglyceride (TG),high density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol (LDL-C) in A group were better than those in B group[(5.20±0.31)mmol/L vs.(5.87±0.46)mmol/L,(2.61±0.29)mmol/L vs.(3.85±0.34)mmol/L,(1.12±0.17)mmol/L vs.(0.93±0.13)mmol/L,(3.03±0.32)mmol/L vs.(3.48±0.41)mmol/L](t=9.355,21.493,6.877,6.702,all P<0.05).There was no significant difference in the total effective rate between the two groups[96.67%(58/60) vs.91.67%(55/60)](x2=1.365,P>0.05).The incidence rate of adverse reactions in A group was lower than that in B group[96.67%(58/60) vs.76.67%(46/60)](x2=6.171,P<0.05).Conclusion Low dose (10 mg) of atorvastatin combined with fenofibrate for mixed type hyperlipidemia has good lipid regulating effect,and adverse reaction is low,has little effect on the liver function of patients,which can effectively improve the prognosis,it is worthy of application and promotion.

Newborn brain damage is the main cause of new-borns' death and disabilities.Current research difficulties lie in analyzing characteristics of cerebral injuries,making objective prognosis and early intervention,as well as analysis of therapeutic effects after recovery.Since subjects are not requested to complete complex tasks while doing resting state functional MRI (rs-fMRI) tests,rs-fMRI is reckoned to be suitable for neonatal brain function research.So far,most rs-fMRI reports regarding cerebral injury are for adults,with only a few have been done on neonates.Foreign research are mainly focused on new borns' brain development.If relevant rs-fMRI research can be done on newborn brain damage,it would be helpful to accurately evaluate structure and function of patients' brain tissue damage.Further research can provide more valuable information in clinics.

Background and purpose:Solitary plasmacytoma of bone(SBP) is a rare disease,reports releveant to this disease are rarely seen. The purpose of this study was to investigate the relation between the clinical features and the prognosis of solitary plasmacytoma of bone. Methods:We reviewed the data of 12 patients diagnosed with solitary plasmacytoma of bone from 1998 to 2007 in Peking University third hospital,the clinical features,treatment and prognosis of the patients were analyzed retrospectively. Results:The age ranged from 37-71 years(mean 49.6 years) ,the male/female ratio was 3 to 1. Immunophenotype analysis showed that 11(91.6%) cases were positive for CD79a,10(83.3%) positive forVS38C,and all negative for CD20. With 12 to 87 months follow-up(average 40?22 months) ,three cases(33%) developed to multiple myeloma,two of them died from infection,the median survival time was 73 months,the 3 year and 5 year survival rate were 90 percent and 75 percent respectively. Conclusion:Middle and old male are more likely to develop SP. The prognosis is good,but some of them can progress to multiple myeloma.

AIM: To investigate the dynamic expression of Rho kinase(ROCK I) and transforming growth factor ?1(TGF-?1) in pulmonary arterioles of rat with chronic thromboembolic pulmonary hypertension.METHODS: Sixty-four male Wister rats were randomly divided into eight groups: beginning control group,embolism for 3 d,1 week,2 weeks,4 weeks,8 weeks,12 weeks groups and end control group.The pulmonary thromboembolism(PTE) model was established by injecting thrombin into jugular vein two times in two weeks and each rat underwent peritoneal injection with tranexamic acid one time a day during experiment to prevent thrombolysis.The mean pulmonary artery pressure(mPAP),right ventricular hypertrophy index(RVHI),relative medial thickness of small pulmonary arteries(PAMT) and vessel wall area/total area(WA/TA) were measured.The levels of ROCK I mRNA and TGF-?1 protein in rat pulmonary artery were determined by in situ hybridization,immunohistochemistry and image analysis,respectively.RESULTS: mPAP,PAMT and WA/TA were higher respectively in embolism from 4 weeks group to 12 weeks group than those in beginning control group(mPAP: all P

Objective:To analyse the methord and effects of intermaxillary traction(IMT)screws used in the treatment of jaw frac-ture.Methods:In the treatment of 1 68 cases of jaw fracture IMT screws were used for the restoration of normal and stable occlusion. The screw number,position,traction effect and postoperative complications of the treatment were analysed.Results:705 screws were used in 168 patients,4 screws were used in each of 147 cased (88%),6 in 12(7%),5 in 9(5%).336(47.7%)screws were fixed between the roots of first and second premolar,292(41 .4%)between the roots of canine and first premolar,50 (7.1%)be-tween the roots of second premolar and first molar,27(3.8%)between the other tooth roots.Normal postoperative occlusion relation was achived by the use of screws in 92 cases without traction.Occlusion disharmony or deviation was found in 76 cases by the used of screws and was restored to normlal by 1 4-day traction in 71 cases.The total efficiency of the treatment was 97%.Pain of the mucosa surrounding the screws was observed in 23 cases (1 3.7%).Root damage,traction screw loosening and adjacent tooth dislocation were observed in 1 3(1 .8%),1 1 (1 .6%)and 2(0.3%)cases respectively.Conclusion:For the fixation of IMT screws,the posi-tions between tooth root from canine to first molar were most common and safe.The fixation point should be in 5 ~8mm below the gin-gival margin.Use of 4-6 screws can meet treatment need.

Objective To analyze the serum samples of young and middle-aged patients with hypertension of different syndromes and healthy patients by means of metabonomics; To confirm its biomarker; To reveal the nature of phlegm dampness retention syndrome in essential hypertension. Methods The syndrome types of 34 hypertension patients were differentiated into 14 cases of liver-fire hyperactivity syndrome group, 14 cases of phlegm dampness retention syndrome group and 6 cases of yin deficiency and yang hyperactivity syndrome group. 15 healthy volunteers were selected as control group. 1H-NMR technique combined with partial least squares-discriminate analysis (PLS-DA) method was used to look for the biomarkers. And the levels of UA, TC and TG were recorded. Results The level of UA in phlegm dampness retention syndrome group was significantly higher than the other three groups (P<0.05). The level of TC in yin deficiency and yang hyperactivity syndrome group was higher and had significantly difference with the control group (P<0.05). The level of TG in phlegm dampness retention syndrome group was higher and had significantly difference with control group (P<0.05). The metabonomics study based on the 1H-NMR method could distinguish the phlegm dampness retention syndrome group from the normal control group, liver-fire hyperactivity syndrome group and yin deficiency and yang hyperactivity syndrome group. Compared with the control group, the levels of acetone, VLDL, and LDL were significantly higher and the levels of lactate, serine, glucose, methionine, alanine were significantly lower in phlegm dampness retention syndrome group; compared with the liver-fire hyperactivity syndrome group, levels of citrate, alanine, VLDL, and LDL were significantly higher and the levels of glucose, lysine, glutamate, proline lactate were significantly lower; compared with yin deficiency and yang hyperactivity syndrome group, the level of creatinine was significantly higher. Conclusion There are lipoprotein metabolism, amino acid metabolism and glucose metabolism disorder in the young and middle-age hypertensive patients with phlegm dampness retention syndrome.
