Objective: To study the lung tissue TLR4 expression and airway hyperresponsiveness(AHR) in the mice infected by respiratory syncytial virus(RSV).Methods:16 clean,6 weeks old BALB/c mice were divided into two groups equally(RSV group and control).One week after RSV infection,AHR was detected by inhaling the increased concentration of methacholine,TLR4 mRNA expression was measured by RT-PCR methods,and the correlation between AHR and TLR4 expression was also analyzed.Results:An important difference was detected in two groups' airway resistance when the inhaled concentration of methacholine was 3.2g/L(P

Pathological changes of Kupffer cells in number and ultrastructure were studied by means of colloidal carbon uptake, endogenous peroxidase cytochemistry, quantitative histology and ultrastructural stereologic morphometry at various time intervals (3,7,14,21,and 28 d) after common bile duct ligation. Kupffer cell phagocytic function and serum fibronectin opsonic activity were measured. The results show the morphological changes of Kupffer cells coinciding with their functional alterations. Alteration of Kupffer cell phagocytic function is mainly due to the changes of number and cellular activity of Kupffer cells.

Objective To explore the relationship between serum hs -CRP,IL -17 levels and senium type 2 diabetic macrovascular complications and its clinical significance.Methods The serum levels of hs -CRP and IL-17 were measured with immunoturbidimetry and ELISA respectively in 80 cases of type 2 diabetic patients with macrovascular complications,80 cases of the absence of any major vascular complications in patients with type 2 diabetes and 80 healthy subjects as the control.Results The serum hs -CRP and IL -17 levels of senium type 2 diabetic Patients with macrovascular complications were significantly higher than those of patients without macrovascular complication and healthy control group(t =19.18,23.14,all P <0.01);And serum hs -CRP and IL -17 levels of seniumtype 2 diabetic patients without macrovascular complications were also significantly higher than those of the healthy control group (t =23.64,19.97,all P <0.05 );While serum hs -CRP and IL -17 levels in different subgroup of type 2 diabetic patients with macrovascular complications were no significantly statistical significance(F =1.08,1.49,all P >0.05);In patients of type 2 diabetic Patients with macrovascular complications,hs -CRP was positively correlated with serum IL -17(r =0.712,P <0.05).Conclusion Hs -CRP and IL -17might be involved in the process of inflammatory response to diabetic macroangiopathy,and may have important role in the pathogenesis of senium type 2 diabetic patients with macrovascular complications.Detemination of hs -CRP and IL -17 levels in type 2 diabetic patients may be useful for early detecting diabetic macrovascular complications and serve as the index in monitoring the state of diabetic macrovascular complications.

Select 106 pregnant women with threatened preterm labor between 28 and 37 weeks of gestation. They have been treated continually by the preventing preterm labor therapy including antibiotics and magnesium sulfate. Cervicovaginal fetal fibronectin (fFN) and C-reactive protein (CRP) in serum were detected before treatment and after 3-day and 7-day treatment respectively. 100 normal pregnant women were included as control group. (1) The fFN and CRP had significant differences between study group and control group (P<0.05). (2) The fFN and CPR were different compared in the treatment period (P<0.05). Fetal fibronectin and CRP can be used can be used in therapeutic effect evaluation of threatened preterm labor.

Objective To study the clinical values of neuron-specific enolase(NSE) as serum tumor marker in lung cancer.Methods The serum NSE levels in 96 patients with lung cancer,60 patients with begnign pulmonary disease and 60 healthy controls were measured by using enzyme-linked immunosorbent assay.Results The levels of NSE in serum in patients with lung cancer was significantly higher than those in healthy subjects and patients with begnign lung disease(P0.05).The effective rate of chemotherapy were 87.10%,40.00% and 66.67%, 33.33% in patients with SCLC and NSCLC,respective for NSE positive and negative ones(P

Objective To study the treatment of postoperative pancreatic fistula. Methods The study (retrospectively) reviewed the management of 20 patients with pancreatic fistula. Fifteen patients were treated (conservatively), and 5 patients were treated surgically. Results All of the patients treated conservatively or by (surgery) were cured,and the results were satisfactory. Conclusions The majority of pancreatic fistulas can be cured with conservative management. If the fistula communicates with the main pancreatic duct or fails to heal after 5 months of conservative therapy, operation is necessary.Pancreatic fistulojejunostomy is a simple, safe and effective method.

Objective To discuss the clinical effect of sublingual misoprostol on planned delivery with full-term pregnancy and influence on outcomes of pregnancy and newborns.Methods Ninety-six puerpera with cervical bishop score ≤ 4 were randomly divided into the control group(n =48) and research group (n =48).The patients of the control group were given oxytocin therapy while the research group were given sublingual misoprostol.The promoting effect of cervical maturity,induced abortion effects,outcomes of pregnancy and newborns between the two groups were compared.Results The total effective rate of cervical maturity of research group was obviously higher than that of control group,the differences were statistically significant (91.7％ (44/48) vs 66.7％ (32/48),x2=7.834,P =0.015).The total effective rate of induced abortion effects of research group was obviously higher than that of control group,the differences were statistically significant (93.8％ (45/48) vs 54.2％ (26/48),x2=9.653,P=0.004).The postpartum hemorrhage((183.6±24.2) ml vs.(216.5±32.6) ml,t=6.748),total stageoflabor((7.6±1.3) h vs.(11.3±2.5) h,t=6.636) and cesarean section rate(31.3％ vs.47.9％,x2 =5.637) of research group was obviously lower than that of control group,the differences were statistically significant (P＜0.05).Two groups of newborns and the incidence of neonatal asphyxia,amniotic fluid pollution had no statistically significant difference(P＞0.05).Conclusion The clinical effect of sublingual misoprostol on.planned delivery with full-term pregnancy is obvious and causes little influence on outcomes of pregnancy and newborns.It is safe and effective to be applied on planned delivery and worth popularization and application.

Objective To explore the influence of ROI size on the diagnostic performance of shear wave elstography (SWE) of breast masses.Methods A total of 225 consecutive patients with 239 solid breast masses underwent SWE before surgery,and then quantitative SWE parameters,including the maximum stiffness (Emax),mean stiffness (Emean),ratio of stiffness of the mass to stiffness of surrounding fat (Eratio) and standard deviation (SD),were measured by two methods,one method was using larger ROI to include the largest part of a mass,and the other was placing fixed ROI=2 mm over the stiffest part of the lesion to measure.The diagnostic performance of the two methods were evaluated by ROC curve,and the cut-off value,sensitivity and specificity of each SWE parameter were obtained.Results There were no statistically significant differences between the performance of Emax,Emean and SD from the two different methods (all P＞ 0.05),the performance of Eratio of the two methods showed significant difference (P=0.046).The significantly higher specificity of Emax and Emean in the larger ROI were found,and the significantly higher sensitivity of SD and Eratio in the ROI=2 mm was found.Furthermore,the diagnostic performance of combination of SWE and BI-RADS were not greatly affected by the ROI size,the difference had no statistical significance (all P＞0.05).Conclusion The ROI size only affects the diagnostic performance of Eratio,and donot affect the diagnostic performance of the quantitative SWE parameters (Emax,Emean,SD) and combination of SWE and BI-RADS.

The disposition of drug in vivo is subjected to a series of biotransformation and transport, depending on the involvement of drug-metabolizing enzymes and transporters.However, the individual capacity varies when metabolizing and transporting the same drug, and pharmacogenomics has trouble in completely explaining the differences.microRNA, a key aspect of epigenetic modifications, is a powerful complement to traditional genetics.Emerging evidences have confirmed that drug-metabolizing enzymes and transporters be controlled by different microRNAs, and the same microRNA also regulates several drug-metabolizing enzymes or/and transporters simultaneously.All of these researches infer that microRNAs are likely to realize the comprehensive macro-regulation of gene expression.The further study of microRNAs maybe a suitable point to research the interindividual variability in disposition of drugs, and it provides a theoretical basis for rational use of drug and individualized medicine.
