Objective To research the relationship among the disc protrusion on MRI, sex, age, course and the clinical types. Methods MRI was performed for 102 patients. The disc protrusion was divided into three types. According to clinical types, the patients were divided into four types. Statistically, age, course, clinical type and protrusion on MRI were analyzed by SPSS13.0. Results The age was not related with the clinical types and disc protrusion on MRI. There were obvious relations between clinical types and course. There were obvious relations between clinical types and disc protrusion. Conclusion The clinical types are very important on diagnosis of disease stages and choice of therapy in treating lumbar disc protrusion.

ObjectiveTo study the relationship between DNA aneuploidy and proliferative activity and the clinical and pathologic features.MethodsDNA ploidy and cell cycle analysis were analyzed in 119 colorectal fresh cancer apecimens using flow Cytometry and prospectively compared with the CEA in serum,tumor size,tumor morphology,lymph node metastases,Dukes' Classfication,histologic type and grade in colorectal cancer.ResultsThere was no relation between serum CEA and DNA aneuploidy and proliferative activity. Aneuploidy was detected at 56.5% in ulcerating carcinoma, which was significantly higher than 14.7% in bulge carcinoma (P<0.01). Aneuploidy was detected at 64.7% in middle and lower grade carcinoma, which was significantly higher than 36.5% of high grade carcinoma (P<0.01). No significant differences in aneuploidy were observed with respect to tumor size, lymph node metastases, Dukes' classfication,tumor histologic type.ConclusionsDNA aneuploidy of cancer cell can express the degree of malignancy of colorectal cancer. But proliferative activity does not relate to all the clinical and pathologic features. CEA in serum does not relate to DNA aneuploidy and proliferative activity.

Objective To estimate reliability of magnetic resonance elastography (MRE) in measuring liver stiffness of volunteers and patients with chronic liver disease and to assess inter-rater consistency.Methods MRE was performed on a 3.0 T scanner in all subjects,including 24 volunteers (control group) and 64 patients with liver disease (chronic liver disease group).Liver stiffness was measured blindly by two raters.The pathological fibrosis score was applied as a standard reference for liver fibrosis in 22 patients.The intraclass correlation coefficient (ICC) was used to evaluate inter-rater reliability.The differences of liver stiffness between two groups were evaluated using non-parametric MannWhitney U test.Spearman analysis was used to analyze the correlation between fibrosis stages and liver stiffness.Results The intraclass correlation coefficient of liver stiffness was perfect (ICC =0.99,P ＜ 0.01)between two raters.There was significant difference of mean stiffness between control group and patient group (U =90.5,P ＜0.01) with(2.35 ±0.34) kPa and(4.17 ± 0.47) kPa,respectively.The correlation between fibrosis stage (3,3,5,5 and 6 patients in fibrosis stage S0,S1,S2,S3 and S4) and stiffness (2.13,3.25,3.82,5.45 and 7.35 kPa) was very strong (r =0.96,P ＜0.01).Conclusion MRE is a reliable and promising tool to measure liver stiffness and to assess liver fibrosis.

To analyze the composition regularity of Carthami Flos-containing prescriptions of the Drug Standards of Ministry of Health of People's Republic of China-Traditional Chinese Medicine Preparations (the ministerial standards for Traditional Chinese Medicine) based on the traditional Chinese medicine inheritance support system (TCMISS, RZDZ No. 0389952). Efforts were made to identify 331 prescriptions containing Carthami Flos and summarize 16 attending functions and 10 commonly used drug combinations. Three commonly used drug combinations were selected for an in-depth analysis on Carthami Flos's combined administration regularity. Based on Carthami Flos's attending functions, its effects in paralysis, traumatic injuries and dysmenorrheal were compared to analyze Carthami Flos's core drug combinations for treating different diseases. The regularity of clinical administration and the characteristics of commonly used drug combinations were summarized to provide reference for Carthami Flos's clinical application and new ideas for new drug R&D. Carthami Flos prescriptions was mainly used to treat blood stasis and pain and mostly combined with drugs that could activate blood, promote the circulation of qi and dispel pathogenic wind to treat Qi-stagnation and blood stasis caused by various pathogenic factors such as wind, cold and dampness.

Objective To explore the protective effect of L-carnitine on neonates with myocardial injury caused by as?phyxia. Methods Forty-four neonates with myocardial injury caused by asphyxia were randomly divided into L-carnitine treatment group (21 cases) and control group (23 cases). Patients in control group were received routine treatment and pa?tients in treatment group were given L-carnitine 0. 1 g/(kg · d) on the basis of routine treatment for 7 days. Symptoms and physical signs were observed before therapy and during the treatment in two groups. Before and after the treatment, plasma levels of free L-carnitine and cardiac troponin I (cTnI) were detected with the method of colorimetric assay and chemilumi?nescent, respectively. Results The clinical effective rate was significantly higher in treatment group than that of control group (90.48%vs 60.87%, P<0. 05). Compared with the control group, there was a significantly higher plasma concentra?tion of free L-carnitine in treatment group after treatment [(27.00±5.69)μmol/L vs (13.20±3.04)μmol/L, P<0.05]. In treat?ment group, plasma concentration of free L-carnitine was significantly higher after treatment than that of pre-therapy [(14.87 ± 3.95)μmol/L,P<0.05]. Compared with the control group, there was a significantly lower plasma concentration of cTnI after treatment in treatment group [(0.025±0.006)μg/L vs (0.046±0.010)μg/L, P<0.05]. In the treatment group, there was a significant correlation between decreased plasma concentration of cTnI and increased plasma concentration of free L-carnitine (r=0.899, P<0.05). Conclusion Administration of L-carnitine can effectively decrease the abnormal plasma lev?el of cTnI in neonates with myocardial injury caused by asphyxia, and thereby protect the myocardium.
