Objective: To explore the effect of valsartan on inflammatory cytokines in patients with hypertension combining paroxysmal atrial ifbrillation (PAF).
Methods:A total of 60 patients with hypertension combining PAF converted to sinus rhythm were studied and the patients were divided into 2 groups. Control group, the patients received felodipine and Valsartan group. n=30 in each group, all patients were treated for 6 months. In addition, there was a Normal group including 30 healthy subjects. The levels of high sensitive C-reactive protein (hs-CRP), interleukin-6 (IL-6) and left atrial diastolic diameter (LADd), the sinus rhythm maintenance rate were examined and compared before and after treatment among different groups.
Results: Compared with Normal group, the levels of hs-CRP, IL-6 and LADd were obviously higher in patients at both Control group and Valsartan group, all P<0.01. With 6 months of treatment, the levels of hs-CRP, IL-6 and LADd were decreased in both groups of patients than they were before, all P<0.01;compared with Control group, such effects were more obvious in Valsartan group, all P<0.01. The sinus rhythm maintenance rate in Valsartan group was signiifcantly higher than that in Control group, P<0.05.
Conclusion: Valsartan may inhibit inflammatory response and improve atrial structure remodeling, therefore better maintain the converted sinus rhythm in patients with hypertension combining PAF. The anti-inlfammatory effect of valsartan might be independent from its anti-hypertension effect.

Objective To study effects of different surgical methods in the treatment of varicose veins of lower limb. Methods A total of 236 cases of varicose veins (319 lower limbs) were treated from January 1994 to January 2005 with different surgical procedures, including 136 cases of high ligation and stripping of the great saphenous vein (184 limbs), 63 cases of high ligation and stripping combined with subcutaneous continuous circumferential suture-ligation (86 limbs), 7 cases of endovenous laser therapy (9 limbs), and 30 cases of minimally invasive arthroscopic reaming (40 limbs; Two mini-incisions were made on the leg to introduce the arthroscope and reamer respectively, and the varicose veins were removed). Results Follow-up observations were made in 207 cases (87.7%, 275 limbs) for 3~12 months (mean, 10.6 months), involving all the 7 cases of endovenous laser therapy and all the 30 cases of arthroscopic reaming. Postoperatively the sense of soreness and dragging pain and claudication disappeared. Chronic ulcers cleared up at 3~6 postoperative weeks in 125 limbs out of 137 limbs. Mild adverse effects of subcutaneous hematoma or local solid feeling subsided within 3~5 weeks. Conclusions Each of the 4 surgical procedures has its own indications. Minimally invasive arthroscopic reaming is a safe, effective and little invasive novel treatment for varicose veins of lower limb.

Objective To understand well this disease,8 children with familial periodic paralysis(FPP) were reported and the(rela)-ted literatures were reviewed.Methods The hereditary characters,clinical manifestations,auxiliary examination and managements were summarized retrospectively in 8 cases of FPP patients hospitalized from January 1996 to December 2005,and etiopathogenis and diagnosis were also analyzed.Results Six cases of FPP were diagnosed as hypokalemic periodic paralysis,and all occured as an autosomal dominant condition.During paralytic episodes,the patients showed obviously low serum potassium levels [1.9-2.8 mmol/L,(2.4?0.38) mmol/L)] and hypokalemic electrocardiogram findings,such as U-wave.The level of blood glucose was lower than normal range.Other 2 cases with normal serum potassium ion level at attack were diagnosed as normokalemic periodic paralysis with autosomal dominant pattern.One of the two cases,the level of blood glucose was lower.Thyroid functions,renal functions and electromyograms were all normal in 8 cases.Conclusions FPP is a group of relatively uncommon inherited disorders known as the skeletal muscle channelophathies.It can be diagnosed by hereditary characters,clinical manifestataions,auxiliary examinations.

Objective To investigate correlations of hyperuricemia and matrix metalloproteinase -9 level with left ventricular remodeling in patients with type 2 diabetes and the clinical effect of intervention for hyperuricemia.Methods 100 type 2 diabetic patients with hyperuricemia in our hospital from June 2011 to June 2012 were selected as hyperuricemia group,50 type 2 diabetic cases with normal uric acid were considered as DM group.Levels of blood glucose,blood lipids,glycosylated hemoglobin and matrix metalloproteinase-9 were detected.All patients underwent echocardiography.Patients in hyperuricemia group were randomly divided into treatment group (receiving allopurinol and alkaline urine-alkalify therapy added to hypoglycemic treatment,n=50) and control group (receiving hypoglycemic treatment,n=50).After 6 months of treatment,levels of blood glucose,blood lipids,glycosylated hemoglobin,matrix metalloproteinase-9 and echocardiography were rechecked.Results The levels of triglyceride (TG),blood uric acid,MMP-9,left ventricular posterior wall thickness (LVPWT),interventricular septal thickness (IVST) and left ventricular mass index (LVMI) were increased in hyperuricemia group versus DM group[(2.3±0.5) mmol/L vs.(1.6±0.30) mmol/L,(498.9±32.5) μmol/L vs.(322.8±35.6) μmol/L,(765±38) g/L vs.(420±26) pg/L,(11.0±1.1) mm vs.(9.2±0.8) mm,(11.5±1.6) mm vs.(10.1±1.1) mm,(138.7±35.6) g/m2 vs.(115.0±10.4)g/m2,t=4.945,5.124,4.895,3.985,3.965,3.989,respectively,all P＜0.05].Levels of TG,blood uric acid,MMP,LVPWT,IVST were decreased in treatment group after treatment versus before treatment [(1.6±0.5) mmol/L vs.(2.3±0.6) mmol/L,(323.0±30.5) μmol/L vs.(496.6±32.6) μmol/L,(766±34) pg/L vs.(410±25)pg/L,(9.1±0.8) mm vs.(11.0±1.1) mm,(9.2±1.1) mm vs.(11.6±1.5) mm,(116±10.5)g/m2 vs.(138.8±35.2) g/m2,t=3.386,4.525,4.865,3.256,3.895,3.985,all P＜0.05].Correlation analysis showed that LVMI had positive correlations with levels of blood uric acid,TG,MMP-9 (r=0.435,0.348,0.356,respectively).Conclusions Hyperuricemia involves in left ventricular remodeling,and therapeutic intervention on the hyperuricemia can reverse this remodeling.

Clinically traditional Chinese medicine (TCM) has been proven to possess obvious anti-tumor effects. It is critical to further explore the effective components and the corresponding mechanism of the TCM against target cells, which also has great significance for developing novel nano-TCM formulations for clinical treatment of tumor. This paper systematically reviews the anti-tumor effects of Chinese herbal compound and the anti-tumor mechanism of single herb. We also summarized the progress in the current traditional nano-TCM preparations. Taking the shikonin in Herba Arnebiae as an example, using the nano-material self-assembly technology, we discussed the design of novel nano-macromolecule TCM formulations while considering the mechanism of single herb and the clinical obstacles.

Objective To study the macrophage colony-stimulating factor(M-CSF)expression levels of serum and synovial fluids from patients with spondyloarthropathy(SPA)and its contribution to the pathogen- esis of SpA.Methods Eleven SpA synovial tissue samples were compared to those from peripheral blood mononuclear cells(PBMC)of 10 normal subjects using a 1176 gene array.M-CSF was detected in both serum samples and synovial fluids by enzyme linked immunosorbent assay(ELISA).Two groups of AS subjects were tested.The first group consisted of 41 ankylosing spondylitis(AS)patients who had not been treated with bio- logics.The second group consisted of 13 subjects whose serum samples were collected before and 14 weeks af- ter initiation of infliximab.These were compared to serum samples from 28 normal subjects,and synovial fluid samples from 15 SpA patients.Results Expression of M-CSF could be detected in both serum samples and synovial fluids.The concentration of M-CSF in the group of 41 AS patients not treated with biologics correlated with the Bath Ankylosing Spondylitis Disease Activity Index(BASDAI)values(r=0.41,P=0.004).Treatment of infliximab in AS patients led to a significant decrease in the values of BASDAI(P=0.000 07),but no signif- icant change in the serum M-CSF values.Conclusion M-CSF is a promising candidate for research on the mechanisms of SpA and its signaling on pathway in SpA is different from tumor necrosis factor(TNF)-?,and it may provide new basis for developing new anti-biologics for SpA.

Mycoepoxydiene is a novel antitumor agent extracted from marine lignicolous fungi HLY-2, which is Diaporthe phaseolorum by molecule identification. The medium optimization for mycoepoxydiene by orthogonal design and the comparison of submerged fermentation and solid state fermentation were studied. The rusult is that the maximal yield of the compound is 543mg/L, which is 43 times compared to the customary half-seawater PD medium and 15 times to the best submerged condition. This optimum culture medium included potato 250g/L, seawater 300mL/L, glucose 30g/L, lactose 50g/L, KH_ 2 PO_ 4 0.65mmol/L and (NH_ 4 )_ 2 SO_ 4 1g/L in the solid state condition. Differentiation analysis between submerged and solid state fermentation, and antitumor activity of these ferment products were also studied. The antitumor activity of products of the optimum medium approached the pure compound.
