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 the protective effect of Hedysari Radix polysaccharide (HRP) on liver fibrosis in mice and the correlation between the hepatic fibrosis and bone loss. Methods: The mice were sc injected with 40% carbon tetrachloride (CCl4) dissolved in olive oil solution (0.1 mL/kg, once every 5 days ), while given high-, mid-, and low-dose (20, 10, and 5 g crude drug/kg) HRP and colchicines (0.6 mg/kg) daily. Continuous 35 d later, the activity of alanine transarninase (ALT) and aspartate transferase (AST), contents of total protein (TP) and albumin (ALB) were investigated by related reagent kit, and then, calculated the albumin/globulin (A/G) ratio, liver and thymus indexes and liver histological of tissue pathology were determined. The serum level of acid phosphatase resistant to acid phosphatase (TRACP), alkaline phosphatase (ALP), Ca, P, and the bone level of hydroxyproline (Hyp) were investigated by related reagent kit to observe bone loss. Results: The model group compared with the Sham group, the levels of ALT, AST, and TP increase, showed obvious liver pathological damage, liver and thymus index increase, levels of TRACP, ALP, Ca, and P decrease, and Hyp increase. HRP could significantly improve the hepatic fibrosis and bone loss induced by CCl4 in mice. Conclusion: The liver fibrosis in mice could also cause bone loss and be the primary cause of bone loss in this experiment. The certain market value of this Chinese materia medica is developed for its significant effect and contact between hepatic fibrosis and bone loss is initially investigated, which lays the foundation to further discuss the mechanism of the above two.

As one of the serious complications of diabetes, diabetic retinopathy( DR) has become a main eye disease which causes blindness. The occurrence and development of DR is related to many factors. The pathogenesis is complicated, and the mechanism has not been clear. Early data suggest that the occurrence and development of DR has relations with many factors such as blood sugar level, diabetes duration and the environment. Among the factors, mitochondrial dysfunction and oxidative stress is the important mechanisms of DR and has become research focus in recent years. Consequences of mitochondrial dysfunction within cells include elevation of the rate of reactive oxygen species( ROS) production due to damage of electron transport chain proteins, mitochondrial DNA ( mtDNA ) damage, and loss of metabolic capacity. Clear understanding on the mechanism of mitochondrial functional change under high sugar level and oxidative stress response in the occurrence and development of DR is of great significance on prevention and cure of DR. ln this article, the development of mitochondrial metabolism and oxidative stress of DR is reviewed.

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.

Objective To investigate the effects of warming-needle acupuncture on the levels of matrix metalloproteinase-1 (MMP-1) and interleukin-1β (IL-1β) in the articular cartilage in knee osteoarthritis induced by immobilization in rabbits.MethodsA total of 30 adult male Japanese white rabbits were randomly assigned into three groups by random number table method: a normal group, a model group and a treatment group, with 10 rabbits in each group. Knee osteoarthritis was induced by 6 weeks of immobilization. The rabbits in the treatment group received warming-needle acupuncture after modeling at points of “Neixiyan” (EX-LE4), “Dubi” (ST35), “Zusanli” (ST36) and “Yanglingquan” (GB34) for 4 weeks. The level of MMP-1 and IL-1β in the articular cartilage of the knee were determined with radioimmunological assay.ResultsThere were significant difference in the levels of MMP-1(0.16 ± 0.02 ng/mg, 0.37 ± 0.02 ng/mg, and 0.28 ± 0.03 ng/mg;F=258.251) and IL-1β (0.21 ± 0.01 pg/mg, 0.34 ± 0.02pg/mg, and 0.31 ± 0.04 pg/mg;F=127.112) among the normal group, model group and treatment group. The levels of MMP-1 and IL-1β both in the model group and treatment group were significant higher than those in the normal group (allP<0.01), while the levels of MMP-1 and IL-1β in the treatment group were significant lower than those in the model group (allP<0.01).ConclusionWarming-needle acupuncture can effectively reduced the levels of MMP-1 and IL-1β in the articular cartilage in knee osteoarthritis induced by immobilization in rabbits.

Objective To explore the effects of early growth response gene-1 (Egr-1) on bone marrow mesenchymal stem cells (BMSC) proliferation and osteogenic differentiation,which is aimed at providing new molecular targets for the treatment of osteoporosis.Methods Bone marrow was collected from adult men and the BMSCs were cultured primarily and observed by microscope.Meanwhile,flow cytometry was used for BMSCs phenotypic identification;After transfection of pcDNA3.1/Egr-1 into BM SCs,the level of BMSCs proliferation was determined by MTT respectively on the 2 d,4 d and 6 d;On the 7 d after transfection,the ALP activity assay was used for testing the ALP activity in BMSCs.And then,alizarin red S-calcium kit was used for measuring the calcified knots respectively on the 7 d,14 d and 21 d;On the 21 d after transfection,real-time qPCR and Western blotting were used respectively for measuring the expression of mRNA and protein of Egr-1,Runx2 and NDRG1;Further,BMSCs were transfected with Egr-1 siRNA,and the content of calcium nodules,ALP activity,the expression of Egr-1,Runx2 and NDRG1 were detected as above methods.Results The cells cultured in vitro showed high level of CD90 and CD29 and very low level of CD34 and CD45,which is accorded with the characteristic of BMSCs.The pcDNA3.1/Egr-1 transfection for BMSCs had no effect on cells prolifera tion.However,the calcified knots,ALP activity and the expression of Egr 1,Runx2 and NDRG1 were increased after transfection of pcDNA3.1/Egr-1 for BMSCs.In addition,Egr-1 siRNA showed the opposite effect with pcDNA3.1/Egr-1 transfection for BMSCs.Conclusion Egr-1 induces osteogenic differentiation of BMSCs by promoting NDRG1 but has no effects on proliferation of BMSCs.
