Objective To compare the clinical effects of extracorporeal shock wave treatment (ESWT) on lumbar ramus posterior nervorum spinalium syndrome and to compare the effectiveness of applying it in X-ray orientation with pain-point orientation.MethodsSixty patients with lumbar ramus posterior nervorum spinalium syndrome were randomly divided into an X-ray orientation group and a pain-point orientation group with 30 subjects in each group.The two groups then received ESWT with the X-ray orientation and pain-point orientation,respectively.The ESWT was delivered at the energy of 0.12 to 0.20 mJ/cm2 and the frequency of 60-80 pulses per minutes.A total of 1000-1500 shock wave pulses were delivered every time.Three sessions of ESWT were administered,with a 3-5 days of interval between each session.The results were rated using the 75 scores of the lumbar function quantification index recommended by Greenough.Ratings were done before treatment,and after the first,the second and the third treatment.ResultsThere was no significant difference between the groups' average index scores before treatment.There were however significant differences from the baseline scores after the first,the second and the third treatments.There was no significant difference in average lumbar function quantification scores between the groups after the first treatment,but the inter-group differences were statistically significant after the second and the third treatments.After three treatments the cure rate in the X-ray orientation group was 76.7％ and overall effectiveness was 93.3％.Both were significantly higher than in the pain-point orientation group (33.3％ and 76.7％ respectively).ConclusionsThe advantages of X-ray orientation when administering ESWT for lumbar rami posterior nervorum spinalium syndrome are more exact positioning and more effective treatment.The effect was obviously better than with pain-point orientation.

Purpose To investigate the value of arterial spin labeling (ASL) in evaluating renal function in patients with renal cell carcinoma (RCC) after laparoscopic partial nephrectomy.Materials and Methods Fifteen patients with RCC undergoing laparoscopic partial nephrectomy were studied prospectively.The patients were performed ASL scan one week before and three months after operation.The correlation between renal blood flow (RBF) value measured by ASL and the glomerular filtration rate (GFR) measured by radionuclide method in the renal cortex of healthy side was analyzed.The RBF values in the kidney of affected side or healthy side were measured,the difference of which between before operation and three months after operation was compared.Results The RBF value and GFR data in the renal cortex of healthy side had positive correlation (r=0.638,P＜0.05).In the affected side of kidney,the RBF value of remaining renal tissue [(291.5 ± 37.3) ml/(100g·min)] compared with that of preoperative renal tissue [(237.8 ± 46.2) ml/(100g·min)]increased about 53.7 ml/(100g · min) (P＜0.05).In the healthy side of kidney,the RBF value of renal tissue [(241.1 ± 50.3) ml/(100 g · min)] compared with that of preoperative renal tissue [(290.4 ± 51.8) ml/(100 g·min)] decreased about 49.3 ml/(100 g·min) (P＜0.05).Conclusion ASL can be used to evaluate renal function,and it is valuable to evaluate renal perfusion function after laparoscopic partial nephrectomy of RCC.

Objective To assess the value of arterial spin labeling(ASL) MRI in the staging of early renal allograft function. Methods Sixty two renal allograft recipients (2 to 4 weeks after kidney transplantation) and 20 age match volunteers were included in this study. All subjects underwent conventional MRI and ASL MRI which was performed in the oblique-sagittal plane. Recipients were divided into two groups according to the estimated glomerular filtration rate (eGFR), recipients with good allograft function (eGFR≥60 ml · min-1 · 1.73 m-2,n=37) and recipients with impaired allograft function (eGFR<60 ml · min - 1 · 1.73 m - 2,n=25). Renal blood flow (RBF) was measured and an intra-class correlation coefficient (ICC) was calculated to confirm the reproducibility of the measured results from two doctors. One-way analysis of variance (ANOVA) and Bonferroni were used to compare the different cortical RBF among three groups. Correlation of RBF with eGFR was evaluated using Pearson correlation coefficients. The receiver operating characteristic (ROC) curve was performed to assess the diagnostic efficacy of using cortical RBF to discriminate allografts with impaired function from good function. Results RBF values showed good reproducibility between doctors with an ICC larger than 0.90 in different group. Mean cortical RBF were (390 ± 61),(290 ± 69),(201 ± 86) ml · 100 g-1 · min-1 for healthy controls, recipients with good and impaired allograft function, respectively(F=37.313,P<0.01). RBF exhibited a significant correlation with renal function as determined by eGFR for recipients (r=0.60,P<0.01). Mean cortical RBF showed a high area under the ROC curve (0.773) to discriminate renal allografts with different function, with a sensitivity of 56.0% (14/25) and a specificity of 89.2% (33/37). Conclusion ASL MRI can assess the early renal allografts perfusion, and provide valuable information in the staging of renal function. It could be a useful method for evaluating renal function noninvasively.

AIM:In this study, the rat lung injury model was induced by ammonium chloride for studying the effect of imidapril on blood gas, serum TNF-α, IL-6 and MDA concentrations, and AngⅡand CD54 protein expression in rat lung tissue.METHODS:Male rats were randomly divided into 3 groups:control group, lung injury model group and drug group.The rats in control group were given saline (2 mL/kg), while the rats in lung injury model group were given 6% ammonium chloride (2 mL/kg).In drug group, imidapril (3 mg· kg-1· d-1) was given to the rats once daily for 1 week by intragastric gavage after given 6%ammonium chloride.On the 7th day, the rats were anesthetized with 2% so-dium pentobarbital.Abdominal aorta blood, venous blood and lung tissue were collected.The blood gas indexes and serum TNF-α, IL-6 and MDA concentrations were determined.The lung tissues were fixed and sliced, and the expression of AngⅡ and CD54 proteins was detected by immunohistochemistry.RESULTS: The PaCO2 increased in lung injury model group compared with control group and drug group (P<0.05).The expression of AngⅡand CD54, and the concentrations of TNF-α, IL-6 and MDA also increased significantly ( P<0.01) in model group.Pulmonary edema, inflammation, alveo-lus congestion, hemorrhage and hyperplasia in model group were obvious compared with control group and drug group. CONCLUSION:Imidapril improves blood gas indexes, and reduces lipid peroxidation and inflammatory responses in the rats with lung injury induced by ammonium chloride.

To discover novel fluoroquinolone lead compounds as possible anti-infective or/and antitumor chemotherapies, combination principle of pharmacophore-based drug design, a series of novel tricyclic fluoroquinolone title compounds, [1,2,4]triazino[3,4-h][1,8]naphthyridine-8-one-7-carboxylic acid derivatives ( 5a-5p), were designed and synthesized with a fused [1,2,4]-triazine ring unit. Their structures were characterized by spectral data and elemental analysis and the in vitro antibacterial and anti-cell proliferation activities were also evaluated. The results showed that the titled compounds exhibited more significant inhibitory activities against drug-resistant bacteria (Methicillin-resistant Staphylococcus aureus and multi drug-resistant Escherichia coli strains) and three tested cancer cell lines (human hepatoma SMMC-7721, murine leukemia L1210 and human murine leukemia HL60 cells). Interestingly, SAR showed that compounds with electron-donating groups attached to benzene ring had stronger antibacterial activity than antitumor activity, but electron-withdrawing compounds displayed more potential antitumor activity than antibacterial activity, especially antitumor activity of nitro compounds was comparable to comparison doxorubicin. Thus, novel triazine-fused tricyclic fluoroquinolones as potent anti-infective or/and antitumor lead compounds are valuable to pay attention and for further development.
