Objective To investigate the effects of Mahuang-Xixin-Fuzi decoction on the plasma levels of interlcukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in allergic rhinitis in rats. Methods Thirty-two Wistar rats were randomly divided into a control group, a model group, a chlorpheniramine group, and a Mahuang-Xixin-Fuzi decoction group, with 8 rats in each group. Allergic rhinitis was induced by ovalbumin sensitization. Rats in the chlorpheniramine and Mahuang-Xixin-Fuzi decoction groups received intragastric administration of 0.01%chlorpheniramine and Mahuang-Xixin-Fuzi decoction 0.4 g (twice daily for 21 days), respectively. The plasma levels of IL-6 and TNF-αwere measured with enzyme-linked immunosorbent assay. Results The frequencies of sneezing (2.4 ± 0.9/30 min vs.18.5 ± 3.6/30 min) and nasal rubbing (4.2 ± 1.5/30 min vs. 31.2 ± 3.7/30 min) in the Mahuang-Xixin-Fuzi decoction group were significantly lower than those in the model group (all P<0.05). The plasma levels of IL-6 (153.00 ± 13.87 pg/ml vs. 230.38 ± 33.92 pg/ml) and TNF-α(21.25 ± 4.62 pg/ml vs. 56.38 ± 7.93 pg/ml) in the Mahuang-Xixin-Fuzi decoction group were significantly lower than those in the model group (all P<0.05). Conclusions Mahuang-Xixin-Fuzi decoction can reduce the plasma levels of IL-6 and TNF-α, and alleviate symptoms in allergic rhinitis in rats.

Objective To investigate the diagnostic value of ST segment elevation in acute myocardial infarction (AMI) occurred in patients after resuscitation.Methods The relevant articles about coronary angiography performed in an emergency for all the post-resuscitation patients without obvious noncardiac cause,regardless of the representation of the electrocardiography were searched in the databases of Pubmed,Ovid medline,EBSCO,CBM,Wanfang and VIP of Chongqing.The meta-analysis was carried out with the data from the included articles using the meta-disc 1.4 software.Results Five articles about retrospective analysis of consecutive patients were included.The meta-analysis of pooled statistics showed the sensitivity 0.59,the specificity 0.86,the positive likelihood ratio (LR) 4.4,the negative LR 0.39,the diagnostic odds ratio (OR) 12.28 and the area under the curve (AUC) 0.85.Conclusions Although the high specificity is in favor of making diagnosis of AMI in post-resuscitation patients,the low sensitivity makes the integrative diagnostic value of using sole ST-segment elevation of ECG relatively low.

The precision radiotherapy adopts the accurate fixation,immobilization,spacial orientation and 3-dimensional calculation & display methods.On three-dimensional direction,stereotactic conformal or intensity modulated radiation therapy with conventional or non-conventional segmentation method is used.So the high dose area is identical with the target on three-dimensional and the dose intensity modulated in the target.It aims to decrease or not increase the radiation dose in the normal organs and tissues around the target when increasing the radiation dose in the tumor target.The technology can improve the partial control rate and the living quality of the patients.

Previous teaching of"Four Classic Subject" of TCM was a passive process for students to learn. Problem based learning (PBL), being an original teaching mode, could provoke activeness and conduce to group spirit of students.However, at present, there were problems such as inadequate teaching ability of teachers, not enough supply of teachers, short of corresponding teaching materials, and lack of independence and group spirit of students, which needed to be solved badly.

Objective To analyze gene expression profile for exploring the function and regulatory network of differ-entially expressed genes in prostate cancer by bioinformatics. Methods The data of gene expression profile in prostate cancer were obtained from GEO database. R software and affy, limma, pheatmap, ggplot2 and other R packages were applied for data mining and bioinformatics analysis. Combined with DAVID and GeneMANIA , dif-ferentially expressed genes and their regulatory networks were annotated. Results These differentially expressed genes with statistical significance were 56 genes, 15 upregulated genes, 41 downregulated genes;these genes were enriched into different subgroups. cav1, slc16a2, cav2, slc16a5, magi2, ptrf, pdlim5, lmod1 and abcc6 were en-riched into the cell membrane component subgroup ofcell component category. cav1, cav2 and ptrf regulated the function of caveolae, they may play an important role in the occurrence and development of prostate cancer. Conclusion Differentially expressed genes between prostate cancer and adjacent tissues assemble a complex regu-latory network. Bioinformatics is a tool for data mining of the regulatory network , which provides ideas and data for the molecular mechanisms in prostate cancer.

Objective To explore the methods and effects of body fractionated stereotactic radiotherapy(X-knife) in the treatment of lung metastases.Methods There were 50 cases with lung metastases were treated by fractionated stereotactic radiotherapy using CT orientation and WiMRT model body X-knife.The diameter of the metastases was 1.0cm-5.0cm.The linear accelerator was 6Mv X-ray.The dose per fraction was 5-12Gy,and the total prescribed dose was 30-52Gy at the margin of the PTV enveloped by 90% insodose curve.Results The metastases complete regression was found 21 fo-cus(18.3%)in CT image,partial regression in 70 focus(60.9%),and the overall effective rate was 79.1%.The effective rate for the focus with diameter less than 3cm was 88.5%,and 59.4% equal or more than 3cm,there was significan differ-ence(P

Objective To introduce the clinical design of the portable and moveable laser light for simulation immobilization.Methods According to the theory of the laser immobilization system,the setting is designed by using current material,such as a ruler of ?-shape and pillar-shape laser light etc.After installation and adjustment,it is used in clinic.Results Patient can be immobilized by CT and this setting.Being simple to operate and convenient to use,this setting can act for the expensive laser position system.Conclusion The material and creation of this setting are rougher,so it needs improvement to insure the accuracy of position.
