Objective To discuss the value of 16-slice spiral CT urography in clinical diagnosis.Methods To compare the images between CR excretory urography,CT and MPR,which are the results of 26 cases who were examined by both CR and 16-slice spiral CT urography.Results From the comparison,it is found that the spiral CT urography images are better than that of the CR excertory urography,and at the same time,the relationship between the parenchyma of the renal,renal pelvis,ureter,bladder and the urinary organs and adjacent structures can be demonstrated clearly.Conclusion The scanning time of the spiral CT is shorter.The machine can not only reconstruct powerfully but also work out better images,and the result is better than CR excretory urography which can not detect some details in its images.Therefore CR excretory urogaphy can be replaced by 16-slice spiral CT urography regardless of its cost.

In order to search for novel inhibitors of Na+/H+ exchanger isoform-1 (NHE-1), nine feruloylagmatine analogues were designed and synthesized from ferulic acid and agmatine. The structures of the synthesized compounds were confirmed by 1H NMR, 13C NMR and mass spectra, among which compounds 5f-5i were novel compounds. The results of preliminary pharmacological test showed that some of the compounds possessed strong NHE-1 inhibitory activity, among which compounds 5a, 5b and 6c were more potent than cariporide in NHE-1 inhibition.

OBJECTIVETo observe the therapeutic effects of continuous plasma filtration absorption (CPFA) treatment on burn sepsis.

METHODSThirty burn patients with sepsis hospitalized in Beijing Fengtai You'anmen Hospital from July 2009 to October 2012 were treated by CPFA for twice besides routine treatment. The blood samples were collected at five sites (A, B, C, D, and E, respectively) of blood purification equipment before and after CPFA, before and after hemoabsorption, and before hemofiltration. The plasma levels of TNF-α, IL-1β, IL-6, IL-10, interleukin-1 receptor antagonist (IL-1RA), soluble tumor necrosis factor receptor (sTNFR) I , and sTNFR-II from sites A, C, and E were determined with ELISA before CPFA was performed for the first time, and those from sites B and D were determined with ELISA after CPFA was performed for the first time. Plasma levels of the above-mentioned cytokines from sites A and B were determined with ELISA before CPFA and after CPFA was performed for the second time. The data of plasma levels of IL-1βP3, IL-1RA, sTNFR-I, sTNFR-II, and TNF-α before CPFA and after CPFA was performed for the second time were collected for calculation of the ratios of IL-1RA to IL-1β and sTNFR-I plus sTNFR-II to TNF-α. The expression rate of human leukocyte antigen DR (HLA-DR) on the CD14 positive monocytes, acute physiology and chronic health evaluation (APACHE) II score, body temperature, pulse, respiratory rate, and leukocyte count of patients were evaluated or recorded before CPFA and after CPFA was performed for the second time. Patients'condition was observed. Data were processed with paired t test.

RESULTSThe plasma levels of TNF-α, IL-1β, IL-6 and IL-10 from site B after CPFA was performed for the second time were significantly lower than those from site A before CPFA was performed for the first time (with t values respectively 7.05, 5.23, 4.73, 2.37, P values below 0.01). After CPFA was performed for the first time, the plasma levels of TNF-α, IL-1β, and IL-6 from site D were significantly lower than those from site C before CPFA was performed for the first time (with t values respectively 5.48, 2. 17, 1.78, P < 0.05 or P <0.01). The plasma levels of all cytokines were close between site B after CPFA was performed for the first time and site E before CPFA was performed for the first time (with t values from 0.04 to 1.05, P values above 0.05). The plasma levels of TNF-α, IL-1β, and IL-6 from site B after CPFA was performed for the second time were significantly lower than those from site A before CPFA was performed for the second time (with t values from 1.87 to 5.93, P <0.05 or P <0.01). The ratios of IL-1RA to IL-1β and sTNFR-I plus sTNFR-II to TNF-α, and expression rate of HLA-DR were increased significantly after CPFA was performed for the second time as compared with those before CPFA (with t values from 3.99 to 7. 80, P values below 0.01). APACHE II score after CPFA was performed for the second time was 11 ± 6, which was lower than that before CPFA (22 ± 7, t =4.63, P <0.01). After CPFA was performed for the second time, body temperature, pulse, and respiratory rate of patients were improved (with t values from 1.95 to 3.55, P values below 0.05) , and the leukocyte count was significantly decreased (t =4.36, P <0.01) as compared with those before CPFA. All patients survived and were discharged with length of stay of (27 ± 31) d, and no adverse effects occurred during CPFA treatment.

CONCLUSIONSCPFA, which combines hemoabsorption and hemofiltration, can facilitate the treatment of burn sepsis by decreasing the level of pro-inflammatory cytokines efficiently, alleviating systemic inflammatory response, and improving the immune status.

OBJECTIVETo study the effect of Zhibai Dihuang Pill (ZBDHP) on urokinase-type plasminogen activator (uPA) and sperm quality in ureaplasma urealyticum (Uu) infection infertile patients.

METHODSRecruited were 80 infertility patients with Uu infection at Andriatrics Clinics and Department of Reproduction, including 130 cases of positive Uu semen and 50 cases of negative Uu semen. Patients with positive Uu semen were randomly assigned to the observation group (72 cases) and the control group (58 cases) according to the visit sequence. All patients took antibiotics for 2 weeks. Patients in the observation group additionally took ZBDHP, 6 g each time, twice daily. Those in the control group additionally took Vit E (100 mg each time, twice per day) and ATP (40 mg each time, twice per day). The therapeutic course for all was 90 days. Semen parameters and uPA contents of the sperm membrane were detected and comparatively analyzed.

RESULTSThe sperm membrane uPA content, the sperm motility, the sperm viability, and the percentage of normal morphology sperm in Uu positive infected patients were lower than those in Uu negative infected patients with statistical difference (P < 0.05), but with no significant difference in the sperm density between the two groups (P > 0.05). There was no statistical difference in pre-treatment sperm membrane uPA contents and sperm parameters between the two groups (P > 0.05). Compared with before treatment in the same group, the sperm membrane uPA content, the sperm motility, the sperm viability, and the percentage of normal morphology sperm obviously increased in the two groups with statistical difference (P < 0.05). After treatment, the sperm membrane uPA content increased more obviously in the observation group, with statistical difference when compared with the control group (P < 0.05).

CONCLUSIONSInfection with Uu leads to decreased uPA content of sperm membrance and the sperm motility. ZBDHP could effectively treat Uu infected infertility possibly through fighting against Uu damaged sperm membrane and make the sperm membrane uPA content return to normal, and elevate the fertilizability of sperms.

OBJECTIVETo explore the relationship between blood stasis (BS) syndrome and coronary lesion in patients with coronary heart disease (CHD).

METHODSSyndrome types of 500 patients collected from multiple centers whose diagnosis of CHD confirmed by coronary angiography were differentiated. And the relationship between BS syndrome, its subtypes, and coronary lesion (affected branches, degree of constriction) were analyzed.

RESULTSThe affected branches of coronary artery in patients of BS syndrome was 2.28 +/- 0.28, while that in the non-BS syndrome patients was 2.07 +/- 0.86, showing significant difference between them (P < 0.05); as compared to patients of non-BS syndrome, the coronary lesions in patients of BS syndrome were mostly multi-vascular, and of more severe degree (P < 0.05). In patients of various BS syndrome subtypes, the average number of affected coronary branches in patients of yang-deficiency subtype was 2.58 +/- 0.65, which was significantly more than the number in patients of other BS syndrome subtypes. The constriction degree of coronary lesions in patients of yang-deficiency BS syndrome subtype were mostly severe or moderate, and single branch lesion was rarely seen, as compared with those in patients of phlegm-stasis obstruction subtype, the difference was significant (P < 0.05). The corresponding correlative analysis showed that close correlation was found between yang-deficiency subtype of BS syndrome and severe coronary constriction with the correlation distance of 0.1899.

CONCLUSIONRelationship between BS syndrome and coronary lesion (its number of branches and degree of constriction) truly exists to a certain extent.
