Microwave ablation is widely applied in clinical practice for its safety,minimal invasiveness and definite effectiveness.This technique,however,is still in the initial stage in the treatment of renal tumors.This article introduces the principles and development of the technique,as well as its experimental researches,clinical application and effect evaluation in the treatment of renal cell carcinoma.

This study is to establish the gastric cold model of rats. After gastric feeding with cold water for 5 weeks and extra iced water bath in the last 2 weeks, model group show distinct physical sign of gastric cold syndrome. The pathology of gastrics reveals gastricism of model group, while treatment group(treated with Fanzuojin Wan) show mild lesion. Elisa detection of model group show that the solution of interleukin-2 (IL-2) is higher than blank group. The difference with significance among model group, treatment group and blank group reveals the success of the establishment of gastric cold syndrome.

Objective To analyze the mechanism of nasal deformity by reviewing the possible pathogenesis and nasal anatomy and to find the effective and reliable operative methods to correct nasal deformities in unilateral cleft lip.Methods 57 patients (37 males,20 females,and range in age from 12 to 25 years,with mean of 18.6 years) with nasal deformities in unilateral cleft lip were available for this study.The nasal deformities were treated with the following surgical procedures according to the different locations and degree Of nasal deformities.The eompositive techniques included:alveolar bone grafting was taken to correct the collapse the nasaI base;a cortical plate was inserted between the two medial crura of the alar cartilage.According to the nasal contours of non-cleft side,the alar cartilage was resected and suspended to its normal and symmetrical position.The alar cartilaginous ring was reconstruction,which maintained the nostril shape 3 month postoperatively.Results A total of 57 cases were treated by the method above,and were ranged with score by operators and patients.93% of cases were evaluated as satisfaction after operation.The follow-up for 3 to 24 months showed that 52 cases had achieved satisfactory effects,5 cases showed the trend to relapse.Conclusion The cause of nasal deformities in unilateral cleft lip is complex.The study has achieved a significant improvement by synthetical correction of deformities of maxilla,cartilage and soft tissues, and the restoration of nasal-labial muscles.The rigid suspending is more important to maintain the nostril contour and avoid relapse.

Objective To detect the differential expression profile of microRNAs between patients with or without gall?bladder stone. Methods Samples from 30 patients with gallbladder stones (GS) and 30 without gallbladder stones (GP) were collected, in which microRNAs expression profiles were examined using high-throughput sequencing instrument Illumi?na HiSeq 2500. MicroRNA sequences were obtained and compared to Genebank and Rfam database for classification. Differ?entially expressed microRNAs were screened, and their target genes were predicted. Significant enrichment analysis of GO and KEGG were performed. Real-time quantitative PCR was performed on selected miRNAs in order to validate their expres?sion. Results Clean tags were obtained from both GS group (n=2 215 832) and GP group (n=1 424 770). A total of 17 mi?croRNAs were differentially expressed between GS and GP groups with statistical significance, among which 9 were up-regu?lated and 8 were down-regulated in GS group compared to those in GP group. GO (Gene ocology) analysis showed that target genes were enriched in ion binding and transport, apolipoprotein binding, calcium channel activity, protein kinase activity, steroid hormone biosynthesis and metabolism. KEGG(Kyoto Encyclopedia of Genes and Genomes)analysis is shown for the target genes enriched in cancer related pathways, including WNT, HIPPO pathways. qRT-PCR validation of some differen?tially expressed miRNAs confirmed the result of high-throughput data analysis. Conclusion The differential expression levels of microRNAs may play an important role in occurrence and development of gallbladder stones.

This study is to establish the gastric hot model of rats. After gastric feeding with ethanol solution for 3 weeks and feeding with extra capsaicin and ethanol solution for another 2 weeks, model group show distinct physical sign of gastric hot syndrome. The pathology of gastrics reveals gastricism of model group, while treatment group (treat with Zuojin Wan) shows mild lesion. Elisa detection of model group show that the solution of interleukin-2 (IL-2) is higher than the blank group. The obvious difference among model group, treatment group and blank group reveals the success of the establishment of gastric hot model.

Objective To investigate the effects of high molecular bio-degradable film on preventing peritoneal adhesion.Methods One hundred and twenty rats were divided into control group,non-bio-degradable film group and polycaprolactone(PCL) group.Animal models of peritoneal adhesion made by operations on rats serve as control group.In the study,non-bio-degradable film and bio-degradable,namely PCL films sensitive to pseudomonas enzyme,were put into the opening of peritoneum.The effect of the films on peritoneal adhesion was examined on 1,3,7 and 30 d after operation.Results Peritoneal adhesion was found in all the rats of control group and very low in PCL group and non-bio-degradable film group.Conclusion PCL film can effectively prevent the formation of postoperative peritoneal adhesion.

Myopia is not only a global public health problem, but also a significant socio-economic problem. There are various hypotheses about the pathogenesis of myopia, which is basically the result of the combination of environmental and genetic factors. Although a large number of epidemiological studies have been carried out on the influencing factors of myopia, most of them are cross-sectional studies, longitudinal cohort studies are relatively few. This paper will summarize the influencing factors of myopia at homeland and abroad in recent years.

Objective:To investigate the pain in patients during the early stages of recovery from maxillofacial surgery under general anaesthesia.Methods: One hundred patients as participants to respone the questionaire of postoperative pain 24 hours after operation. The data of pain intensity,analgesia requirement and the reason for operation of the patients were collected and analyzed. Results: Among the 100 cases, 92 with moderate or slight postoperative pain, 8 with severe pain. It is significant more severe pain (14.3%)in the group of bone fracture than that (less than 8.7%) in other groups. Conclusion: Most patients 24 h after maxillofacial surgery are with moderate and slight pain. The pain intensity relates with type of maxillofacial surgery.

Objective To solve the encountered problem of lack of space and dyskinesia of detector in dual energy X-ray absorptiometry system, Methods The method used PartitionMagic8.0 software to partition space in hard disk and added the load to keep the detector balance for moving, Results The original software can run in hard disk, and the pulleys are not gotten force from side. Conclusion The reason of problem is analyzed to find the method that can reduce the percentage for system failure and improve precision and accuracy of data.

By means of cell hybridization in situ with digoxigenin labeled probe, we detected the expression of C-myc protooncogene in peripheral blood mononuclear cells from 31 SLE patients and 10 healthy persons. The results showed that the level of C-myc mRNA in SLE patients was significantly higher than that in normal controls, and the increased level correlated with disease activity. There was also a positive correlation between C-myc mRNA and serum levels of ANA, anti-dsDNA, IgG, C3. Our study indicates that C-myc gene is important for the pathogenesis of SLE.
