Four key attributes,position,rate,shape and force,are programs of pulse tracing put forward by ZHOU Xue-hai,a medical practitioner in late Qing dynasty.The essences of four key attributes are'images'of di erent levels.There are complex relationships between pulse tracing and position,rate,shape and force attributes,which include not only subordinate relationship and static-dynamic relationship between four attributes but double relationship between four attributes and pulse tracing.

Many studies show that transforming growth factor-β (TGF-β) can suppress tumor by inhibiting proliferation and dedifferentiation of cells and promoting cell apoptosis at early stage.But during the progression of tumor,its tumor-promoting action will be more and more obvious with the variation of TGF-β itself and its signal path.TGF-β signal path inhibitors have anti-tumor activity,but the clinical effects and side effects still need to be observed.

AIM: To investigate the effect of Se-containing spirulina phycocyanin (Se-SPC) on liver injury of mice induced by carbon tetrachloride (CCl 4). METHODS: The mouse model was conducted by intragastric feeding with 2% CCl 4 oil for three times, meanwhile Se-SPC, spirulina phycocyanin (SPC) and Na 2SeO 3 were injected (ip) to various groups for 7 days. Then selenium (Se), glutathione peroxidase (GPx), superoxide dismutase (SOD), alanine aminotransferase (ALT), malondiaoldehyde (MDA) and nitric oxide (NO) levels in blood and liver were measured. RESULTS: The level of Se, GPx and SOD activities were obviously higher ( P

Objective To investigate the clinical efficacy of fluoroscopy-guided intestinal adhesion lysis, as a new non-surgical method, in treating incomplete adhesive small intestinal obstruction in order to improve the therapeutic results of adhesive intestinal obstruction. Methods A total of 93 patients with incomplete adhesive small intestinal obstruction were enrolled in this study. The patients were divided into study group (n=49) and control group (n=44). Fluoroscopy-guided intestinal adhesion lysis together with restoration of inter-intestinal loop enterocele was carried out for the patients of the study group , while traditional conservative surgical therapy was employed for the patients of the control group. The study group was comparable with the control group in patients’ age, gender, medical history, disease course, X-ray findings, etc. Results Of the 49 cases in the study group, complete cure was obtained in 40 with a cure rate of 81.6%. The mean hospitalization day was 0.3 day, and the average operation time was 3.25 hours. Among the 44 patients in the control group, complete cure was obtained in 37 with a cure rate of 84.1%. The mean hospitalization day was 7.6 days, and the average therapeutic time was 183.26 hours. Conclusion For the treatment of incomplete adhesive small intestinal obstruction , the therapeutic efficacy of fluoroscopy-guided intestinal adhesion lysis together with restoration of inter-intestinal loop enterocele is better than that of traditional conservative surgical therapy.

Objective To assess and compare the overall diagnostic value of positron emission tomography(PET)-CT and DWI in lymph node staging in patients with prostate cancer by using Meta-analysis.Methods Relevant English articles published on PubMed,EMBASE,Cochrane Library and SCI database were searched.Subsequently,the characteristics of the included articles were appraised and extracted.Statistical analysis was performed employing Meta Disc version 1.4.Heterogeneity of the included articles was tested,which was used to select proper effect model to calculate the pooled sensitivity and specificity and the corresponding 95% CI,summary receiver operating characteristics(SROC) curve was performed and the area under the curve was calculated.The diagnostic performanceincluding the sensitivity,specificity,and the area under the curve was compared between the two groups via x2 test and Z test respectively.Results Eleven of 182 retrieved articles were included,in which 3 articles used two methods of imaging examination at the same time.In PET-CT group,there were eight articles using 11C-Choline as imaging agents,three with 18F-Fluorocholine.The pooled sensitivity and specificity and area under SROC curve for PET-CT were 0.64 (0.574.71),0.93 (0.90-0.96),and 0.8795 respectively.They were 0.59 (0.47-0.70),0.82 (0.70-0.91),and 0.7707 for DWI group.The specificity of PET-CT was significantly higher than that of DWI (x2=5.531,P<0.05).No significant differences were found in the sensitivity and AUC between the two groups (x2=0.528,Z=1.699,P>0.05).Conclusion For lymph node staging in patients with prostate cancer,PET-CT has an equal sensitivity and a higher specificity,a better diagnostic performance compared with DWI.

OBJECTIVETo discuss the clinical effect of closed reduction and interlocking intramedullary nailing in the treatment of femoral shaft fracture.
METHODSFrom March 2006 to December 2011,103 patients with femoral shaft fracture were treated by closed reduction and interlocking intramedullary nailing including 76 males and 27 females with an average age of 36 years old ranging from 19 to 55 years old. According to AO classification,there were 64 cases with type A,27 with type B, 12 with type C. Thirteen cases were open fractures including 5 cases with Gustilo type I , 8 with Gustilo type II . The time of bone healing were observed after operation, the knee function recovery was evaluated by HSS scoring standard at 1 year after operation.
RESULTSThe intraoperative complications included femoral neck fracture in 1 case and proximal femoral fracture in 1 case,both of the patients were treated with reconstructive intramedullary interlocking nail and the fractures healed postoperatively. One patient was suffered from common peroneal nerve injury,which were fully recovered at 4 months later after medical treatment. All the patients were followed up from 12 to 28 months (averaged 22 months). All of the fractures were healed well and the average healing time was 3 to 9 months (averaged 5 months). All the hip joints were recovered to normal function. The average HSS was 90.89±5.06 at 1 year after operation.
CONCLUSIONInterlocking intramedullary nailing is the preferred treatment for patients with femoral shaft fracture. Carefully operating and closed reduction can reduce the complications.

Objective To investigate the effect of incomplete cryoablation on the biological behavior of prostatic cancer RM-1 cells and its mechanism.Methods RM-1 cells of prostatic cancer were placed in -20℃ icebox to be frozen for 5 min.After the recovery of the cell state,the RM-1 cells were frozen again for 10 min and 15 min successively.After culture for one day,the cellular morphology was microscopically examined.A total of 20 C57/BL mice were used to establish the tumor-bearing models,which were randomly and equally divided into the control group and the incomplete cryoablation group with 10 mice in each group.At scheduled time points the tumor lesion size was measured for all mice.The mice were sacrificed at 14 days,the lung tissues were collected and were stained with lE;the numbers of metastatic lesions in the lung were calculated.Transwell assay was used to test the cell migration and invasion,immuno-blotting method was adopted to determine the epithelial-mesenchymal transition-related (EMT-related) protein expression level,and the enzyme-linked immunosorbent assay (ELISA) was employed to check the secretion volume of transforming growth factor-beta (TGF-β).Results After incomplete cryoablation,RM-1 cells became disorderly arranged,their morphology was changed,and antenna structure might be formed.At 3 and 7 days after cryoablation,the tumor size in the incomplete cryoablation group was slightly smaller than that in the control group,but only the difference at 7 days after cryoablation was statistically significant between the two groups (P=0.019).At 10 and 14 days after cryoablation,the tumor volume of the two groups was almost equal.The pulmonary metastatic lesions in the incomplete cryoablation group were obviously much more than those in the control group (P<0.001).Transwell assay indicated that the cell migration and invasion ability in the incomplete cryoablation group was stronger than that in the control group (P<0.05).Immuno-blotting test revealed that,when compared with the control group,in the incomplete cryoablation group the expressions of N-cadherin,MMP-9 and Vimentin were up-regulated,while the expression of E-cadherin was downregulated.ELISA test showed that increased secretion of TGF-β was observed in the incomplete cryoablation group.Conclusion Incomplete cryoablation can enhance the migration and invasion ability of RM-1 cells,increase the number of pulmonary metastatic lesions in tumor-bearing mice,and affect the EMT-related protein expression level.
