Objective To investigate changes in the intraocular pressure(IOP) and anterior chamber angle in patients with chronic renal failure before and after hemodialysis. Methods Fifty?eight patients(116 eyes) with chronic renal failure were measured with Goldmann applanation tonometer and anterior segment optical coherence tomograph. The patients were divided into three groups based on gonioscopy results:the narrow angle group(22 eyes),the Iris neovascular group(3 eyes)and the open angle group(91 eyes). IOP was measured by Goldmann applanation tonometer in patients in the three groups before and after hemodialysis. Anterior chamber angle opening distance (AOD) was detected by anterior segment optical coherence tomograph before and after hemodialysis. The blood urea nitrogen,creatinine,albumin were also determined before and after hemodialysis. All changes in the parameters were analyzed with a paired t test. Results The IOP in narrow angle eyes and in neovascular eyes increased significantly after hemodialysis ,while the IOP in open angle eyes showed no significant changes. The AOD decreased significantly after hemodialysis. The blood urea nitrogen and creatinine decreased significantly in 58 patients,while albumin increased after hemodialysis. Conclusion The IOP in narrow angle eyes and in neovascular eyes increased after hemodialysis ,correlating with the resistance increase of aqueous outflow pathway and the change of plasma osmotic pressure. As a result ,it is recommended that the condition of eye of patients with chronic renal failure should be checked ,and patients should receive appropriate controlling measure or treatment before hemodialysis.

Aim To study the effect of novel AChE inhibitors, 2-phenoxy-indan-1-one derivatives (YKY-1~7), against glutamatic acid-induced neurotoxicity in PC12 cells and on learning & memory impairment in dementia model mice induced by A?25~35 icv Methods The PC12 cells were preincubated with different concentrations of YKY-1~7 for 24 h and subsequently treated by glutamatic acid, at the high concentration of 2 mmol?L-1 for 15 min to induce cytotoxicity. The cell viability was assessed with MTT method.. Dementia model mice were made by intracerebroventricular injection (icv) of aggregated A?25~35. From the next day, the model mice were administered YKY-7 (2.5, 5, 10 mg?kg-1, ig) for 10 consecutive days and sham control mice or A? model control mice received daily ig saline. After the final treatment, the passive avoidance learning was tested, regional cerebral blood flow at cerebral cortex was assessed, and the activity of AChE in the cerebral cortex, hippocampus and blood serum were determined. Results Six out of the seven YKY compounds appeared to be effective against glutamatic acid-induced neurotoxicity in PC12 cells, with YKY-7 demonstrating the most activity. YKY-7 significantly ameliorated the learning and memory ability in dementia model mice induced by A?25-35 icv, slightly and selectively inhibited the cortical and hippocampal AChE, and gently increased the blood flow at cerebral cortex. Conclusion Some of 2-phenoxy-indan-1-one derivatives reported here have protective effects against glutamatic acid induced neurotoxicity in PC12 cells, and improve the learning and memory impairment induced by A?25-35, which may be partly attributable to its selective inhibition of AChE activity in the cerebral cortex and hippocampus.

BACKGROUND: As a micro-injurying and reduplicative treatment of osteoarthritis,the arthroscopic debridement has got the affirmation of numerous scholars. But as one of the standard procedures in artnroscopic debridement,synovectomy is called in question recently.OBJECTIVE: To explore the applied value of synovectomy in the arthroscopic debridement of osteoarthritis.DESIGN: Retrospective controlled analysis.SETTING: Department of Orthopaedics, Fushun Central Hospital.PARTICIPANTS: Sixty-five patients received synovectomy in the arthroscopic debridement of knee joint osteoarthritis in the Department of Orthopaedics,Fushun Central Hospital from February 1997 to December 2000.Thirty-two among them,with complete data and over 1 year's followup,were taken for synovectomy group. Forty-eight patients received the arthroscopic debridement of knee joint osteoarthritis without synovectomy in the Department of Orthopaedics,Fushun Central Hospital from January 2001 to November 2003.Thirty among them,with complete data and over 1 year's follow-up,were taken for control group.METHODS: Synovectomy was taken as the factor of intervention in the operation to perform grouping. The analysis of curative effect was performed to control with joint douching,corpus liberum removal,osteophyma cleaning,meniscus fitting,cartilage gouging,synovectomy and without synovectomy or part synovectomy. Lysholm evaluation standard of knee joint osteoarthritis was used to the knee joint functional evaluation beween preoperation and postoperative 1 year in two groups. And operative time,postoperative draining quantity,postoperative 7-day visual analog score,postoperative 1-year Lysholm score of knee joint, were recorded.MAIN OUTCOME MEASURES: Preoperative and postoperative 1-year Lysholm score of knee joint,operative time,postoperative draining quantity,postoperative 7-day visual analog score.RESULTS: Sixty-two patients were included and all of them entered the result analysis.The preoperative patients in two groups were comparable with each other and the differences of Lysholm score were not significant (t=0.127,P=0.899).The operative time was longer in synovectomy group than in control group,the differences were significant (t=9.547,P ＜ 0.001)and the postoperative draining quantity was more in synovectomy group.The postoperative visual analog score was bigger in synovectomy group than in control group and the differences were significant [the scores of synovectomy and control groups were respectively (4.6±1.1),(2.8±1.4),t=6.206,P ＜ 0.001].The differences of knee joint score in 1-year follow-up were not significant [the scores of synovectomy and control groups were respectively (77.6±11.9),(79.0± 10.3),t=0.562,P=0.576].CONCLUSION: Synovectomy can not increase the curative effect in the near future in the arthroscopic debridement of osteoarthritis. On the contrary,the operative time was longer,the operative wound was larger and postoperative reaction was more serious. It should not be used in the debridement generally.

OBJECTIVETo evaluate the efficacy and safety of testosterone undecanoate (TU) in the treatment of late-onset hypogonadism (LOH) by meta-analysis.

METHODSWe searched Pubmed (until April 1, 2014), Embase (until March 28, 2014), Cochrane Library (until April 17, 2014), CBM (from January 1, 2001 to February 2, 2014), CNKI (from January 1, 2001 to February 2, 2014), Wanfang Database (from January 1, 2000 to February 2, 2014), and VIP Database (from January 1, 2000 to Febru ary 2, 2014) for randomized controlled trials of TU for the treatment of LOH. We evaluated the quality of the identified literature and performed meta-analysis on the included studies using the Rveman5. 2 software.

RESULTSTotally, 14 studies were included after screening, which involved 1 686 cases. Compared with the placebo and blank control groups, TU treatment significantly increased the levels of serum total testosterone (SMD = 6.22, 95% CI 3.99 to 8.45, P < 0.05) and serum free testosterone (SMD = 4.35, 95% CI 1.86 to 6. 85, P < 0.05) but decreased the contents of luteinizing hormone (WMD = -2.23, 95% CI -4.03 to -0.42, P < 0.05), sex hormone binding globulin (WMD = 2.00, 95% CI 1.38 to 2.63, P < 0.05). TU also remarkably reduced the scores of Partial Androgen Deficiency of the Aging Males (WMD = -9.49, 95% CI -12.96 to -6.03, P < 0.05) and Aging Males Symptoms rating scale (WMD = -2.76, 95% CI -4.85 to -0.66, P <0.05) but increased the hemoglobin level (SMD = 2.35, 95% CI 0.29 to 4.41, P < 0.05) and packed-cell volume (SMD = 4.35, 95% CI 1.36 to 7.33, P < 0.05). However, no significant changes were shown in aspertate aminotransferase, alanine transaminase, prostate-specific antigen, or prostate volume after TU treatment (P > 0.05).

CONCLUSIONTU could significantly increase the serum testosterone level and improve the clinical symptoms of LOH patients without inducing serious adverse reactions. However, due to the limited number and relatively low quality of the included studies, the above conclusion could be cautiously applied to clinical practice.

OBJECTIVETo explore the effect of emodin on endoplasmic reticulum (ER) stress of pancreatic acinar AR42J cells.

METHODRat pancreatic acinar AR42J cells were cultured in 6-well plates, and divided into the normal control group, the model group (with the final concentration at 1 x 10(-7) mol · L(-1) for cerulean and lipopolysaccharide at 10 mg · L(-1)) and the emodin group (10, 20, 40 μmol · L(-1)). Cells in each group were cultured in three multiple pores for 24 h, and their supernate was removed after cell attachment. The normal control group was added with haploids, the model group was added with the modeling liquid for haploids, and the treatment groups were added with different concentrations of emodin at 15-20 min before the modeling liquid. The cells were continuously cultured for 3 h under 37 °C and 5% CO2. Their intracellular protease and lipase expressions were detected with kits. The cellular morphology was observed under optical microscope. The level of calcium in endoplasmic reticulum was measured under laser confocal microscopy. Western blot assay were used to determine the protein expression of ER-related signaling molecules.

RESULTEmodin could significantly inhibit levels of amylase, lipase and intracellular calcium and ER.

CONCLUSIONEmodin could reduce pancreatic acinar cell injury induced by the combination of cerulean and lipopolysaccharide. Its action mechanism is correlated with the inhibition of intracellular calcium overload and ER stress.

Objective We aimed to use 1H-MRS to characterize metabolite concentrations in the bilateral hippo?campus in GPI patient. Methods Metabolite ratios in the bilateral hippocampus were compared between patients with GPI (n=52) and Normal Control (NC) (n=38). Clinical neurological tests were measured in all subjects and were correlat?ed to the metabolite concentrations. Results The GPI patients showed significantly lower concentrations of N-acetylas?partate(NAA)/creatine(Cr) ratios in the bilateral hippocampus region compared to the NC subjects. There was significant?ly difference in the NAA/Cr ratios between the mild GPI dementia and the severe GPI dementia groups on the left hippo?campus region. We found that the NAA/Cr ratios concentrations were positively correlated with Mini Mental state Exami?nation (MMSE) and Montreal Cognitive Assessment scale (MoCA) scores in the left hippocampus region and the mI/Cr ra?tios concentrations were positively correlated. Conclusions GPI Patients have neuronal dysfunction in the bilateral hippo?campus. The severity of cognitive impairments is associated with the severity of the damage in the left side.

Objective To assess the application of three-dimensional digital subtraction angiography (3D-DSA) in evaluation of ruptured intracranial aneurysm after clipping and to discuss the different variable use of vol-ume rendering(VR), gradient rendering (GR) and maximum intensity projection (MIP). Methods From January 2011 to December 2012 , 88 patients with 92 ruptured intracranial aneurysms were treated with clipping using titani-um clips in our hospital and followed up by both 2D-DSA and 3D-DSA. Residual aneurysms , Clips place, clips and parent arteries and stenosis of parent arteries were evaluated by volume rendering (VR), gradient rendering (GR) and maximum intensity projection (MIP). Results Among 92 clipped aneurysms, 23 residual aneurysms were found by 3D-DSA. Residual aneurysms were recorded according to the Sindou grade: 15 of gradeⅠ, 3 of gradeⅡ, 4 of grade Ⅲand 1 of grade Ⅳ. Three patients of grade Ⅲand 1 of grade Ⅳwith residual aneurysms were retreated by clipping or coiling, and 1 patient of grade Ⅲ was dead with rupture of residual aneurysm. The clips and number of clips were clearly visualized , and relationship between the clips and the aneurysms was well demonstrated by VR, GR and MIP images. VR, GR images showed the remnants clearly. Three-dimensional digital subtraction angiography did not showed accurate details of the stenosis of parent arties which required an analysis of 2D-DSA. Conclusion Three-dimensional digital subtraction angiography can be used for definite evaluation of resid-ual aneurysms after clipping, especially by VR, GR images. It is helpful to manage the residual ruptured aneurysms.
