Objective To evaluate the therapeutic efficacy of retrobulbar injection with triamcinolone acetonide (TA) for macular edema caused by retinal vein occlusion (RVO). Design Retrospective case series. Participants 21 eyes of 21 patients with macular edema caused by RVO. Methods Retrobulbar injection with TA 40 mg was performed on 21 eyes. The visual acuity, intraocular pres-sure, fundus fluorescein angiography (FFA) and macular central thickness under the optical coherence tomography (OCT) were recorded and analyzed before and after treatment. The follow-up duration was 6-11 months. Main Outcome Measures The visual acuity and the macular central thickness of OCT. Result Visual acuity was improved at the end of follow-up in 16 eyes (76.2%) and unchanged in 5 eyes (23.8%). Macular central thickness was (287.55±121.70) μm at the end of follow-up and (617.23±185.58) μm before treatment. The difference was statistically significant(P=0.000). After treatment, the comparison of visual acuity and macular central thickness be-tween CRVO patients and BRVO patients, as well as between ischemic RVO patients and non-ischemic RVO patients had no significant difference (P>0.05). In patients of course less than 6 months, the visual prognosis after treatment is better than that of before treatment (P=0.011, 0.01), while in patients of course more than 6 months, no difference of vision could be detected before and after treatment (P= 0.583). The result of FFA showed decrease of fluorescein leakage. During follow-up, intraocular pressure of all patients was in the nor-real range. Recurrence of macular edema was found in 8 eyes 2 to 6 months after treatment. Conclusions Retrobulbar injection with TA is a safe, effective, and easy method to treat macular edema caused by RVO. Early treatment can get better efficacy. (Ophthalmal CHN, 2009, 18: 254-256)

Yohimbine (0. 5~4mg ? kg-1, sc) and idazoxan (2~8 mg ? kg-1,sc) showed a dose related antagonistic action on the inhibitory effect of xylazine (4mg ? kg-1,sc) on the gastrointestinal propulsive motility in mice. Xylazine (2mg,4mg ? kg-1,sc),clonidine(120 ?g ? kg-1,sc) exhibited the inhibitory effect of gastrointestinal basic electrical rhythm on the stomach, duodenum, jejunum and ileum in rats.The inhibitory effects of these drugs were the strongest at 30 min after administration of Compounds. Yohimibine (4mg ? kg-1,sc) was found to antagonize the inhibitory effect of xylazine (4mg ? kg-1,sc) on the gastrointestinal basic electrical Rhythm.

Objective To evaluate the application of intra-aortic balloon counterpulsation(IABP) in acute myocardial infarction(AMI) with cardiogenic shock.Methods The study enrolled 65 AMI patients with cardiogenic shock and all the patients underwent primary PCI treatment.Among them,30 patients had IABP suppont during operations.Results In all the 30 cases with IABP support,the hemodynamic parameters improved in 30 minutes and stabilized in 2-8 hours.There was no reocclusion and death during querations.The death rate of the IABP group during hospitalization was 40%.Among the other 35 patients without IABP support,6 patients died during PCI and the in hospital death rate was 74.3%.Conclusion IABP can improve hemodynamic parameters and the perfusion of coronary artery in patients with cardiogenic shock.It can increase the success rate of primaty PCI,reduce the risk of low cardiac output and reocclusion during operation.IABP support during PCI can also improve the prognosis and reduce the motality rate of AMI patients with cardiogenic shock.

Objective To investigate the feasibility and application scope of the looping technique by using a gooseneck snare and a loach guide wire in retrieving tubular foreign bodies within the vascular or ureteral duct. Methods During the period from July 2009 to Dec. 2013, six patients with ruptured catheter were admitted to authors’ hospital. All six patients were females. Three patients had internal ruptured peripherally inserted central venous catheter (PICC), one patient had ruptured implantable venous access port catheter and two patients had replacement of double “J” ureteral catheter stent. By using looping technique, i.e. a loach guide wire and a gooseneck snare were separately placed at the two ends of the tubular foreign body, then the gooseneck snare entangled the soft leading end of the loach guide wire to form a annular structure to seize the ruptured tubular catheter and then to pull it out of the body. Results With the help of the looping technique, the internal ruptured catheter or the double “J” ureteral catheter was successfully removed in all the six patients. Conclusion For the retrieval of the tubular foreign bodies within the vascular or ureteral duct, the looping technique by using a gooseneck snare and a loach guide wire is an effective and fast treatment. Therefore, this technique should be recommended in the clinical practice.

Objective To evaluate the diagnosis value of urodynamics in patients with benign prostate hypertrophy(BPH).Method With urodynamic device,the full set of urodynamic exam was administrated in 427 patients with BPH,and the externalsphincter urethral myogram was monitored simultaneously in pressure-flow studies(PFS).The umdynamic finding such as Q_(max),P_(det)-Q_(max),DS(descending slope)and post-voiding residual(PVR)were recorded,as well as the situation of bladder detrusor constraction and bladder compliance and urethral sphincter coodination.The bladder outflow obstruction was diagnosed by A-G nomogram,P-Q plot and DS.The IPSS score and prostate volume were also acquired.Results The diagnostic rate of BOO is 81.5%,among them concomitantly detrusor muscle impair in 117 cases (27.4%),decreased bladder compliance in 162 case(37.9%),urethral sphincter dyssynergia in 148 cases(34.7%),and unstable bladder in 164 cases(38.4%).The increase degree of BOO show an increasing tendency with urodynamic finding such as Q_(max),P_(det)-Q_(max),P_(open),DS,IPSS score and prostatic volume respectively,but a decreasing tendency with Q_(max) and bladder compliance.Conclusions The urodynamic exam plays an important role in diagnosis of BOO.There is a positive relation among degree of BOO with urodynamic findings such as P_(det)-Q_(max),P_(open),DS and IPSS score and prostatic volume,however,a negative relation with Qmax and bladder compliance respectively.

[Summary] Diabetic nephropathy is one of the major chronic microvascular complications of diabetes ,which is the leading cause of end‐stage renal disease ,as well as the main cause of death in diabetic patients. Glomerular endothelial cell is an important component of the glomerular filtration barrier ,which is directly related to the materials of circulation ,and it can be easily damaged by glucose ,lipid and inflammatory factors. Under the hyperglycemia ,the PKC pathway ,the polyol pathway and oxidative stress were activated ,producing an excess of advanced glycation end products and reactive oxygen species ,which damage the endothelial nitric oxide synthase ,reduce the generation of nitric oxide ,while produce a large number of Ang Ⅱ. Ang Ⅱ damage the endothelial cell. In addition ,there are crosstalk between glomerular endothelial cells and endothelial cells ,which also cause endothelial cell injury. Here ,we reviewed the role of endothelial cell injury in the pathogenesis of diabetic nephropathy.

AIM: To observe anti inflammatory, anti bacterial and immune regulation effects of shuyanling soft capsule. METHODS: The dimethylbenzene induced the degree of ear swelling in mice and turpentine induced proliferation in rats were used to observe the anti inflammation effects of shuyanling soft capsule. The anti bacterial effects were observed both in vitro and in vivo. The immune regulation effects were studied by the splenocyte proliferation response, the activity of antibody producing cells and the phagocytosis of leukocyte in mice. RESULTS: Shuyanling soft capsule inhibited dimethylbenzene induced the degree of ear swelling in mice and turpentine induced proliferation in rats, protected the mice from the infections of staphylcoccus aureus and salmonella typhi, and repressed sixteen kinds of bacterium in vitro. Furthermore, the capsule remarkably enhanced the phagocytosis of neutropil and increased the activity of spleen antibody producing cells and the transformation of the T and B cell in spleen in mice. CONCLUSION: Shuyanling soft capsule has anti inflammatory, anti bacterial and immune regulation effects.
