Objective To observe the efficacy of Qingre Jiangzhuo prescription in the treatment of overweight subjects of type 2 diabetes mellitus. Methods Two hundred and four cases were divided into 2 groups in a randomized, paralleled, contrast, prospective study. The control group was treated with metformin tablet and the trial group was treated with Qingre Jiangzhuo prescription. The efficacy and safety of the two groups were compared on HbAlc, FBG, P2BG, TC, TG, BMI and AE after 12 weeks. Results After treatment, all indexes of the trial group were markedly improved compared with before treatment (P 0.05). The rate of AE in the trial group was less than that in the control group. Conclusion Qingre Jiangzhuo prescription has curative effect on type 2 diabetes mellitus patients with better safety.

Objective To observe the effects of vitamin C (VC) and E (VE) on the uhrastrueture of liver, kidney and brain tissue of fluorosis rats. Methods One hundred and twenty Wistar rats were chosen as the experimental animals and were divided into 9 groups randomly. The control group were given distilled water and the fluoride exposed group were given distilled water containing sodium fluoride 150 mg/L. The throe VC-fluoride exposed groups were given VC orally in a dose of 50,100,150 mg·kg-1.d-1, respectively, and the three VE-fluoride exposed groups were given VE of 25,50,75 mg·kg-1·d-1, respectively. The VC-VE-fluoride exposed group were given VC of 100 mg·kg-1·d-1and VE of 50 mg·kg-1·d-1at the same time of high fluoride water intake. The rats were sacrificed after 9 months and the ultrastructure changes on liver, kidney and brain tissues of each group were observed under transmission electron microscope(TEM). Results The uhrastrueture of liver, kidney and brain showed pathologic changes in the rats that drank water containing high eoneentrations of sodium fluoride. ①Edema of hepatocytes, smeared mitochontria and nuclear matrix, lipid droplet in eytoplasm of hepatocytes, margination of nueleohs as well as obvious swelling of liver sinusoidal endothelial were observed in fluoride exposed group. ② There were marginafion of heterochromatin, expansion of cell space and endoplasmic reticulum in the kidney after the exposure to excess fluoride.③Signifieant changes were found on glial eells on the brain, including cell swelling, increase and marginafion of heterochromatin in the fluoride exposure group. There were no significant uhrastrueture changes in the VC or VE intervention group, while the VC-VE-fluoride exposure group was almost the same as the control group. Conclusions Fluoresis may cause damage on liver, kidney and brain in rats. VC and VE, alone or combined, have protective effects, and the combined supplementation was stronger than single supplementations.

Objective To investigate the effect of Ulinastatin on the delivery of cytokines in patients with septic shock.Methods It was a prospective and controlled clinical study.Seventy-eight patients with septic shock were randomly divided into control group and treatment group and thirty-nine in every group.Patients in treatment group received Ulinastatin 200 000 units intravenous everyday for 3 days,while those in control group received equal volume of normal saline as placebo.At different time points (at 24 th,48 th,72 th hour after start of treatment),the levels of tumor necrosis factor-alpha (TNF-?),interleukin-1 (IL-1),interleukin-6 (IL-6 ),interleukin-8 (IL-8) and superoxide dismutase (SOD) in serum were assayed.Results In comparison with control group,the levels of TNF-?,IL-1,IL-6,IL- 8 of treatment group decreased markedly (P＜0.05,P＜0.01) at different time points,whereas the level of SOD was higher markedly (P＜0.05,P＜0.01) at various time points.Conclusion Ulinastatin has protective effect on patients with septic shock through decreasing the levels of TNF-?,IL-1,IL-6,IL-8 and increasing in the level of SOD.

Rsm (repressor of secondary metabolite) A is an mRNA binding protein which functions as a global repressor to control multiple genes at the posttranscriptional level. Using homologous recombination technique a chromosomal rsmA inactivated mutant strain M-18R was constructed in Pseudomonas sp. M-18, a strain of plant-growth-promoting rhizobacteria, which could inhibit several soilborn phytopathogens by producing secondary metabolites including phenazine-1-carboxylic acid (PCA) and pyoluteorin (Plt) in one single strain. To further study the effect of RsmA on the synthesis of Plt and PCA in the wild type strain M-18, the dynamic curves of Plt and PCA produced respectively by M-18 and M-18R were measured in KMB medium under different temperature conditions such as 37 degrees C constant, 28 degrees C constant and nonconstant (37 degrees C 4 hours at first and then 28 degrees C constant) cultivation. The synthesis of both Plt and PCA were almost inhibited in the cultures under the condition of 37 degrees C. At 28 degrees C, however, compared with the wild type strain M-18, the mutant strain produced tenfold amount of Plt, while the production of PCA decreased only about 50%. When cultivated under the nonconstant condition, the amount of Plt produced by M-18R could reach 400 microg/mL while the PCA production was not significantly affected, but in the wild type strain M-18, the amount of Plt production decreased obviously while the PCA production was not affected in comparison with the results at 28 degrees C constant. These results suggest that a temperature sensitive factor exists to function as an activator independent of RsmA to promote the synthesis of Plt in the rsmA mutant strain M-18R while it may bind with RsmA to repress the synthesis of Plt in the wild type strain M-18. But this factor did not exert any affect on the synthesis of PCA.

The endothelium plays an important role in maintaining vascular homeostasis, regulating vascular tone and blood flow, and preserving a non-thrombogenic blood-tissue interface, and the normal function of the vascular endothelium is essential for penile erection. In most cases, erectile dysfunction (ED) is accompanied by endothelial dysfunction, and endothelial injury is a major pathological basis of ED, which can be induced by bad lifestyles, cardiovascular diseases, reactive oxygen species, and inflammatory mediators. The vascular endothelium is capable of self-repairing, and endothelial injury results from the unbalanced factors of injury and repair. This review focuses on the mechanism and repair of endothelial injury and the relationship of endothelial injury with ED.

Objective To discuss the key points of endovascular therapy for complex subclavian artery occlusive diseases. Methods During the period from January 2012 to December 2013, a total of 92 patients with complex subclavian artery occlusive disease were admitted to Xuanwu Hospital of Capital Medical University, Beijing, China. The clinical data were retrospectively analyzed. The features of the lesions, the success rate of endovascular therapy, the use of combined approaches, the relief of symptoms after treatment, etc. were evaluated. Results The complex subclavian artery occlusive diseases could be divided into three types. Type Ⅰ: long segment of the left subclavian artery was occluded; type Ⅱ: ostial stenosis or occlusion of the right subclavian artery; and type Ⅲ: subclavian artery stenosis or occlusion was associated with the ostial disorder of the vertebral artery, or the opening of vertebral artery was affected by the subclavian artery stenosis or occlusion. The technical success rate was 82.6%. Combination use of femoral artery and brachial artery approach was employed in 27.2% of patients, which had improved the technical success rate. After the treatment the symptom improvement rate was 81.6%. Conclusion Upper limb artery approach can improve the re-canalization rate of left subclavian artery with long segment occlusion, and can ensure the accurate positioning of stent at the site of right subclavian artery opening. During the procedure of endovascular intervention for subclavian artery occlusion disease, attention should be paid to the protection of the vertebral artery.

OBJECTIVETo compare the characteristics of interbody fusion achieved using hat type cervical intervertebral fusion cage (HCIFC) with those of an autologous tricortical iliac crest graft, Harms cage and Carbon cage in a goat cervical spine model.

METHODSThirty-two goats underwent C(3, 4) discectomy and fusion in which the following were used: Group 1, autologous tricortical iliac crest bone graft (8 goats); Group 2, Harms cage filled with autologous iliac crest graft (8 goats); Group 3, Carbon cage filled with autologous iliac bone (8 goats); Group 4, HCIFC filled with autologous iliac graft (8 goats). Radiography was performed pre- and postoperatively and after 1, 2, 4, 8, and 12 weeks. At the same time points, disc space height, intervertebral angle, and lordosis angle were measured. After 12 weeks, the goats were killed and fusion sites were harvested. Biomechanical testing was performed in flexion, extension, axial rotation, and lateral bending to determine the stiffness and range of motion. All cervical fusion specimens underwent histomorphological analysis.

RESULTSOne week after operation, the DSH, IVA and LA of HCIFC and Carbon cage were statistically greater than those of autologous iliac bone graft and Harms cage. Significantly higher values for disc space height, intervertebral angle and lordosis angle were shown in cage-treated goats than in those that received bone graft over a 12-week period. The stiffness of Harms cage in axial rotation and later bending were statistically greater than that of other groups. Radiographic and histomorphologic evaluation showed better fusion results in cage groups than in autologous bone group.

CONCLUSIONSHCIFC can provide a good intervertebral distractability and enough biomechanical stability for cervical fusion.
