Objective To investigate the influence of atorvastatin on tumor necrosis factor - α (TNF- α) of sepsis rats.Methods Sepsis models were established using male SD rats by cecal ligation and puncture (CLP).A total of 100 healthy rats were divided into 4 groups ( n =25) randomly ( random number):sham- operation group,CLP group,low- dose atorvastatin group and high -dose Atorvastatin group.Blood samples of 5 rats in each group were collected at postoperative 0,3,6,12 and 24 hours,to detect tumor necrosis factor - α (TNF - α) levels in plasma.Observe and compare the mobility of rats in each group and specimens of small intestine were taken for histopathological examination by optical microscope.Results At 0 hour,plasmic TNF - α levels in 4 groups were statistically equal (P ＞ 0.05 ).In plasma of sham - operation group,changes of TNF - α levels were not obvious.Compared with CLP group,TNF - α levels in low - dose and high - dose Atorvastatin groups were both significantly lower ( P ＜0.01 ) at postoperative 3,6,12 and 24 hours.And TNF-α levels in high -dose Atorvastatin group were significantly lower than those in low - dose group ( P ＜ 0.01 ) at the 4 time points.The mortality of sepsis was higher in CLP model group than other groups,That of Atorvastatin group was significantly lower than CLP model group but higher than control group and high - dose group was lower than low - dose group.Conclusions Atorvastatin can inhibit the expression of TNF - α in blood plasma of sepsis rats and reduce inflammatory reaction.

Objective To study the relationship between common photoallergens and melasma.Methods Twenty allergens were selected according to the National Diagnostic Criteria for Photosensitive Dermatitis induced by cosmetics,National Diagnostic Criteria for Contact Dermatitis induced by cosmetics and National Diagnostic Criteria for Occupational Skin Diseases.Based on the standard procedures for photopatch test recommended by the British Photodermatology Group (BPG),photopatch test was performed on 50 patients with melasma and 30 normal controls.Results The positivity rate of photopatch test was 48.0%(24/50)in patients suffering from melasma,significantly higher than in the controls[23.33%(7/30),P<0.05].Conclusion Patients with melasma appear more likely to have positive photopatch test than normal controls.

AIM: To observe the effect of crocetin on the apoptosis and the changes of its related regulating proteins caspase-3 and Bcl-2 expression induced by hydrogen peroxide (H_2O_2) in cultured cardiomyocytes. METHODS: Changes of cellular morphology were detected under microscope. Apoptosis rates of the cells were analyzed by PI staining with flow cytometry. Expressions of caspase-3 and Bcl-2 proteins in the cells were determined by immunofluorescence with flow cytometry. RESULTS: In the concentrations used, more severe morphological changes with higher apoptosis rate of the cultured myocardial cells were seen in each H_2O_2 group than that in control group. When treated with 1?10 -4 mol?L -1 H_2O_2, the caspase-3 was increased and Bcl-2 protein decreased remarkably in the cells. But each dosage of crocetin, especially the highest one (5?10 -5 mol?L -1, P

ObjectiveTo assess the safety and efficacy of contrast-enhanced ultrasound (CEUS)-guided percutaneous microwave ablation (MWA) treatment of renal carcinomas.MethodsFifteen patients with 17 renal tumors were retrospectively analyze. The patients’ ages were in the range of 46-80 years (65.2±9.4 years), the tumor diameters were in the range of 1.1-3.9 cm (2.3±0.7 cm) and biopsy pathological results were renal cell carcinoma. All of the tumors were inconspicuous on conventional ultrasound, while conspicuous on contrast enhanced-computed tomography (CT) or magnetic resonance imaging (MRI). Seventeen tumors were ablated under the guidance of CEUS.ResultsAll tumors were successfully visualized on CEUS and MWA was performed under CEUS guidance. The durations of energy application for each tumor were in the range of 5-11 min (mean± SD 7.3±2.2 min). The mean session of CEUS-guided MWA for each tumor was 1.1±0.3. All patients were followed up for 3-49 months (median, 17 months) to observe the therapeutic effects and complications. There was no local tumor progress and major complication. ConclusionCEUS-guided PMWA is a safety, efficient and feasible therapy for patients with RCC which is inconspicuous on conventional US.

Objective To study on the association of apolipoprotein E(apoE)genotype with coronary heart disease(CHD)and type 2 diabetes mellitus(T2DM).Methods PCR-RFL,multiplex amplification refractory mutation system(muli-ARMS)and PCR-SSCP methods were used to detect the genotype of apoE,and DNA sequencing technique were used for further confrm the genotype and gene variations in 2 446 Chinese individuals,including 238 cases of CHD,316 cases of T2DM and 1 892 healthy controls.Fasting blood glucose(FBG)and plasma lipids levels[TC,TG,HDL-C,LDL-C,apoA I,apoB and Lo(a)]were measured by usual methods.Results Compared with the controls,plasma HDL-C(t=2.66)and apoA I(t=2.30)levels in the CHD group were significantly lower(P<0.05),but not in T2DM group;plasma TC level(t=5.22)in the T2DM group were significantly higher(P<0.05),but not in CHD group;systolic pressure(t=8.48,5.74)diastolic pressure(t=5.66,3.35),plasma TG(t=3.38, 4.56),LDL-C(t=2.48,7.00),apoB(t=1.67,2.24),Lp(a)(t=4.16,4.15)and FBG(t=7.04, 16.93)levels were significantly higher in both CHD group and T2DM group(P<0.05).The distributions of apoE ε2/2,ε2/3,ε3/3,ε2/4,ε3/4 and ε4/4 respectively were 0.4%,13.4%,58.0%,1.3%, 26.5%,0.4% in the CHD group;0.6%,5.7%,72.8%,1.9%,14.9%,4.1% in the T2DM group; 0.5%,10.5%,69.6%,1.6%,16.8%,1.1% in the control group.Significant differences were found between the CHD group(χ2=14.90,P=0.00),T2DM group(χ2=7.08,P=0.03)and the control group for the frequencies of apoE genotype.The distribution of ε3/4 was higher(26.5% vs 16.8%)and ε3/3 Was lower(58.0% vs 69.6%)in the CHD group.In the T2DM group.the distribution of εε4/4 Was higher (4.1% vs 1.1%),and 2 cases of ε3/3 with Arg 150 His mutation in exon 4 of apoE gene were firstly reposed in China,which is none in the CHD and control groups.Conclusions The results suggested that apoE ε3/4 and ε4 genotypes might be associated with the susceptibility of CHD and T2DM.respectively. To some extent,apoE ε3/3 may not be a good genotype for T2DM because of the Arg 150 His mutation. Blood pressure and plasma lipids could be used for diagnosis of the two diseases.
