Objective To investigate the emergency treatment and correlation factors of aqueous misdirection during glaucoma and cataract surgery in glaucoma patients.Design Retrospective case series.Participants 126 cases(132 eyes)of angle-closure glaucoma patients with aqueous misdirection during surgery,100 cases(100 eyes)of angle-closure glaucoma patients without aqueous misdirection during surgery and 100 cases(100 eyes)of senile cataract patients.Methods We performed pars plana vitreous water-bag aspiration or anterior vitrectomy on glaucoma patients with aqueous misdirection during surgery.All the factors in observation group and control groups were compared and analyzed by logistic regression.Main Outcome Measures Preoperative highest intraocular pressure(HIOP),intraocular pressure after maximum dose(IOP),anterior chamber depth(ACD),lens thickness(LENS),axial length (AXL),mean keratometry(K),intraocular lens diopter within-0.5D corrected by SRK-T formula(IOLD).Results Among all the 132 angle-closure glaucoma eyes whose posterior chamber pressures were increased during surgery,we performed pars plana vitreous water-bag aspiration in 123 eyes(93.18%),and anterior vitrectomy in 9 eyes(6.8%).Postoperative complications included shallow anterior chamber in 20 eyes(7 eyes with malignant glaucoma,9 eyes with choroidal detachment,4 eyes with delayed local suprachorodal hemorrhage),and vitreous local hemorrhage in 1 eye.Means of all the observation indexes on three groups showed significant difference(all P

Objective: To investigate factors related to alexithymia of patients with essential hypertension or type 2 diabetes mellitus. Method: 42 patients wi th essential hypertension, 40 with diabetes mellitus and 45 healthy control were assessed by TAS (Toronto Alexithymia Scale), SCL-90 and EPQ (Eysenck Personalit y Questionnaire). Multiple correlation analysis and multiple stepwise regressio n were used in data analysis. Result: Compared with normal contr ol, patients with hypertension or diabetes showed alexithymia. They were deficient in the abilit y of describing emotion, recognizing and distinguishing between emotion and body feeling, and used to extroversion thought. Besides these, patients with diabete s showed fancy-lacking either. There was close relation between personality and a lexithymia. The more introversive of the hypertensives, the more deficient they were in describing emotion. The more introversive of the diabetics, the more de f icient they were in recognizing and making distinguish between emotion and body feeling. Hostility ideation and neuroticism of hypertension patients were major factors related to alexithymia. Paranoid ideation and psychoticism had similar e ffects in diabetics. Conclusion: Patients with essential hypert ension or diabete s have alexithymia relating to their personality traits and psychological state .

Objective To investigate the effect of eosinophils(EOS)in asthmatic guinea pigs airway and explore the mechanism of antiasthma by inhaled arsenic trioxide. Methods The guinea pigs asthma models were established with ovalbumin(OVA)challenge method,2 groups received inhaled different doses of arsenic trioxide,and three control groups respectively received normal saline inhaled and high dose of arsenic trioxide by intraperitoneal injection and dexamethasone(DEX)intraperitoneally. EOS invaded and apoptosis with all of the groups were assessed after 7 days intraperitoneal injection or inhalation. Results Compared with group of inhaled normal saline, both EOS invaded and apoptosis in bronchus submuconsa were significantly different(P0.05)among groups of inhaled low dose arsenic trioxide [2.0 mg(kg?d)]and intraperitoneal injection with higher dose arsenic trioxide[5.0 kg/(kg?d)]and DEX[10 mg/(kg?d)]for these two parameters. Conclusions The mechanism of arsenic trioxide antiasthma with arsenic trioxide can decrease EOS amount in bronchial submucosa and accelerate EOS apoptosis, and relieve bronchial inflammation in asthma. For inhaled lower dose arsenic trioxide or intraperitoneal injection with high dose arsenic trioxide ,the effect of EOS is equivalent. The antiasthma effect of inhaled lower dose arsenic trioxide[2.0 mg/(kg?d)]is equivalent to intraperitoneal injection higher dose[5.0 mg/(kg?d)],and may be safe comparatively. The mechanism of antiasthma by inhaled arsenic trioxide is the same with DEX.

Objective To determine the prevalence and prognostic implication of hypocalcemia in the set-ring of acute myocardial infarction. Method The study consisted of 1274 consecutive patients presenting with a-cute myocardial infarction. Plasma calcium concentrations were obtained on the 1st day, 2nd day, 3rd day after admission. According to the plasma calcium concentrations, 1274 patients with AMI were designed into four groups:group A (Ca2+≥2.20 mmol/L),gronp B (2.00～2.19 mmol/L), group C (1.90～1.99 mmol/L),group D (Ca2<1.9 mmol/L). Echocardiographic examination was performed on day 2 or 3 of hospitalization.Results There were 606 patients (47.6%) having hypocalcemia, defined as a plasma calcium level <2.2mmol/L. Among them, there were 476 patients(37.4%) in group B(2.00～2.19 mmol/L), 73 patients(5.7 %)in group C (1.90～1.99 hanoi/L) and 45 patients(3.5%)in group D(Ca2+< 1.90 retooL/L). The mortality of group A was 2.5 %, on the contrary, the mortality of the other groups was 7.8 %, 20.5 %, 17.8 %. The difference was significant. In multivariate logistic regression analysis, hypocalcemia was independently associated with 30-day mortality. Conclusions Hypocalcemia in patients with acute myocardial infarction is an independent predictor of 30-day mortality.

AIM:To investigate the effects of Zhenwu decoction ( ZWD) on the expression of α-smooth muscle actin (α-SMA) and NF-κB in diabetic nephropathy ( DN) rats.METHODS:Diabetic rat model was induced by intrape-ritoneal injection of streptozotocin ( STZ) , and the animals were randomly divided into STZ group ( n=22) and STZ+ZWD group (n=23).The normal rats served as control (n=16).All rats were sacrificed on 8 weeks after modeling.Biochemical assay and pathological observation ( HE staining and transmission electron microscopy ) were used to evaluate the effects of Zhenwu decoction on the renal function and pathological morphology .The body weight , renal index , blood glucose , total urinary protein in 24 h, and superoxide dismutase ( SOD ) , malondialdehyde ( MDA ) , inducible nitric oxide synthase ( iNOS) were determined as well .Western blotting was used to observe the effects of Zhenwu decoction on the expression ofα-SMA and NF-κB in diabetic nephropathy ( DN) rats.RESULTS:Compared with normal group , the renal index , blood glucose concentration, total urinary protein in 24 h, blood urea nitrogen (BUN), serum creatinine (SCr) and MDA were significantly higher and body weight was lower in DN rats (P<0.05).Pathological examination of the kidneys in DN group showed glomerular hypertrophy , glomerular basement membrane thickening , tubular epithelial cell degeneration , me-sangial matrix proliferation , protein cast formation in some renal tubules .The protein expression levels of α-SMA and NF-κB were markedly increased (P<0.05).After ZWD treatment, the level of renal index, total urinary protein in 24 h, BUN, SCr and the expression of α-SMA and NF-κB at the protein level were significantly decreased (P<0.05).The renal histological injury in ZWD group was significantly ameliorated .CONCLUSION: Zhenwu decoction might protect kidney against STZ-induced injury via decreasing the expression of α-SMA and NF-κB.

How to remove the well fixed cement or cementless prosthesis and get a completely distal cement removal in the rTHR are critical to the outcome of revision. Because of higher rate of union, excellent intraoperative exposure, and adjustment of abductor tension, ETO has been widely applied to rTHR and complicated primary THR by foreign scholars. Furthermore, this technology has wide indications, very few contraindications, high cure rates,and low complications rate. ETO turns out to be a safe and effective revision technology. In the article, the indication, contraindication, complications and advantages of this technique were reviewed.
