To observe the clinical efficacy of Artisan iris-clip intraocular lens ( lOL) implantation on cataract with a wide range of lens dislocation.
●METHODS: Twenty-four hospital patients (28 eyes) of cataract with lens subluxation by trauma (20 patients, 20 eyes) and Marfan's syndrome (4 patients, 8 eyes) during May 2007 to December 2011 were selected. All of them underwent phacoemulsification or an anterior vitrectomy and Artisan iris - clip lOL implantation at stage Ⅰ. Postoperative visual acuity, corneal endothelial cell count, intraocular lens position and postoperative complications were observed. Follow-up time was 6mo.
●RESULTS: Compared with the preoperative, postoperative best corrected visual acuity improved to varying degrees, visual acuity of 0. 1-0. 5 was in 20 eyes, 0. 5-1. 0 in 8 eyes. After followed up 1-6mo, no artificial lens shift, iris inflammation, iris atrophy and corneal decompensation and other complications were observed.
●CONCLUSlON: Cataract surgery with a wide range of lens dislocation is difficult, but as long as surgeons who have a wealth of clinical experience and superb skills, still can carry out phacoemulsification surgery or anterior vitrectomy and Artisan iris - clip lOL implantation and obtain a better outcome.

Obsessive-compulsive disorder (OCD) is a chronic,disabling,mental disorder,which has been linked to significant abnormalities in certain brain areas,including the orbital frontal cortex and the anterior cingulate cortex.Neuroimaging studies have also shown that brain areas related to the decision-making function include the orbital frontal cortex and the dorsal prefrontal lobes.Furthermore,the association between OCD and decision-making function has been consistently demonstrated from a neurobiological perspective.Clinically,impaired decision-making ability is commonly observed in OCD patients,and there is a correlation between OCD and abnormal decision function.Decision-making tasks are typically divided into two types,decision-making under risk and decision-making under ambiguity,with the former commonly evaluated using the Iowa Gambling Task (IGT) and the latter using the Game of Dice Task (GDT).In this article the neural mechanism and evaluation methods of decision making in OCD were reviewed.

To explore an effective method with few operative complications for treating circumferential mixed hemorrhoids (CMH).Sixty three cases of CMH (Group A) were treated with limited external incision and internal ligation combined with restoration of intervenient skin and 34 cases (Group B) were treated with traditional external incision and internal ligation as control. Anal canal diameter (ACD), anal canal quiescent pressure (ACQP) and anal canal systolic pressure (ACSP) were determined before and after operation. Short term and long term therapeutic effects were also observed and compared in the two groups.Short term and long term therapeutic effects in Group A were better than those in Group B (P

Objective To investigate the condition of exercise, medicine compliance and the rehabilitation of patients with arteriosclerosis obliterans (ASO) in lower extremity after the surgery, and also to study the influence of self-efficiency and social support to their rehabilitation. Methods The questionnaire survey was performed in 102 patients who had surgical or interventional therapy of arteriosclerosis obliterans in the lower extremity in our hospital, investigated the general information of the patients, their knowledge of postoperative rehabilitation, medicine compliance, exercise condition, general self-efficiency and social support. Results The postoperative time for the patients with arteriosclerosis obliterans was 2 to 22months, the knowledge rate for postoperative rehabilitation was 7.8%-46.1%.The Morisky score for the patients of taking medicine for the treatment of vascular disease was 2.0,and there was only 6 patients(5.9%)with good medicine compliance. There were 22 patients(21.0%) had completed the ambulation training according to the guidelines, and there were 25 patients(24.5%) had completed the Buerger training. The self-efficiency score of the patients was 2.78 ± 0.76, and the gross score of social support was 32.38 ± 7.89. Spearman correlation analysis shows that the Morisky score for the patients of taking medicine for the treatment of vascular disease was in positive correlation with self-efficiency (r=0.289, P=0.003), but in negative correlation with social support (r=–0.286, P=0.006). Conclusions Most of the patients with arteriosclerosis obliterans have poor medicine compliance, and do not do exercise as required by the guidelines. Patients with high self-efficiency demonstrates medicine noncompliance, however the enhancement of social support will help patients improve their medicine compliance.

0.05).However,A-waves were recorded in 7 patients who were with normal F-waves.Conclusion The occur- rence of A-waves,especially of multiple type,in the ulnar and median nerves might be helpful for the early diagnosis of Guillain-Barr?Syndrome.

OBJECTIVETo investigate the emergency treatment for large amputated ear defect.

METHODSFrom Feb. 2010 to Oct. 2013, 5 cases with large unilateral amputated ear defects were treated. The amputated auricular cartilage was replanted subcutaneously in mastoid area at the first stage. Cranioauricular sulcus was reconstructed and skin grafting was performed at the second stage.

RESULTSAll cases were followed up for 3-6 months with satisfactory result. The reconstructed helix, scapha and cavity of auricular concha had similar color and elasticity as the ear at healthy side. Scar at donor sites, such as inguinal region and armpit, was inconspicuous.

CONCLUSIONSThe method of auricular cartilage replantation is an effective way for emergency treatment of large amputated auricular defect with less morbidity at donor site.

OBJECTIVETo study the effects of Citalopram on the mRNA expression of bax and bel-2 in frontal cortical neurons and on cell apoptosis of rats after stress.

METHODSTwenty-four healthy male SD rats were randomly divided into three groups (n = 8). The control group did no receive any treatment, the stress group was subject to stress and given normal saline and experimental group was given Citalopram irrigation stomach after stress. Rats were forced to swim to establish chronic stress model (15 min/d, 4 weeks), bax, bcl-2 mRNA expression were tested by in situ hybridization technique (ISH), TUNEL assay was used to determine cell apoptosis, Nikon image analysis software were used to measure the number of positive cells in each index.

RESULTSCompared with the control group, the stress group showed a larger number of bax mRNA expressing cells( P < 0.01), a smaller number of bcl-2 mRNA expressing cells (P < 0.01), and the staining intensity of positive cells was significantly reduced( P < 0.01). Compared with the stress group, the experiment group showed more reduced number of bax mRNA positive cells( P < 0.01) and significantly increased bcl-2 mRNA positive cells( P < 0.05), a small amount of positive cells were found, compared with that in the stress group, nuclear condensation in the experimental group was reduced significantly and the staining was obviously weaker( P < 0.01).

CONCLUSIONCitalopram significantly antagonizes bax mRNA and potentiatesbcl-2 mRNA protein expression and inhibits apoptosis of rat prefrontal cortical neurons caused by chronic stress, which might be one possible mechanism of Citalopram for prevention and treatment of psychosis caused by chronic stress.

Objective To investigate the effects of sevoflurane pretreatment on renal ischemia-reperfusion (I/R)-induced apoptosis in kidney in rats. Methods Thirty pathogen-free male SD rats weighing 220-260 g were randomized into 3 groups (n=10 each):group control (group C);group I/R and group sevoflurane(group S). Renal I/R was induced by clamping the left renal pedicle for 45 min in I/R and S groups. In group S inhalation of 2.2% sevoflurane in O2 was started at 30 min before operation and maintained throughout the experiment.Venous blood samples were taken at 3 h of reperfusion for determination of serum BUN and Cr concentrations. The animals were then sacrificed and the left kidneys were removed for microscopic examination, detection of apoptosis(by TUNEL)and determination of heme oxygenase-1(HO-1) mRNA and protein expression (by RT-PCR and Western blot).Results Renal I/R significantly increased serum BUN and Cr concentrations, apoptotic index(percentage of apoptotic cells) and the severity of necrosis of renal proximal convoluted tubules (0=normal,4=necrosis of whole segment of proximal convoluted tubules).Sevoflurane inhalation attenuated the I/R-induced changes mentioned above.HO-1 mRNA and protein expression was up-regulated by I/R and HO-1 mRNA expression was further up-regulated by sevoflurane inhalation.Conclusion Sevoflurane pretreatment can protect kidney against I/R injury by attenuating cell apoptosis.Up-regulation of HO-1 mRNA expression may be involved in the mechanism.
