To observe the complicated cataract after glaucoma surgery, analyze the causes and summarize the treatments, in order to provide the basis for clinical treatment.
● METHODS: Forty - five patients ( 50 eyes ) with complicated cataract after glaucoma surgery treated in our hospital from October 2012 to September 2013 were selected. All patients were treated by 3. 2mm tunnel incision phacoemulsification cataract operation. The postoperative complications, intraocular pressure, and visual acuity were observed.
●RESULTS: After treatment, visual acuity of all patients were improved, without obvious complications, the intraocular pressure was normal.
●CONCLUSlON: 3. 2mm tunnel incision phacoemulsification cataract operation can effectively improve the intraocular pressure and promote the recovery of visual acuity.

BACKGROUND: Because the continuity and integrity of the trachea are likely damaged to some extent after tracheostomy, the implementation of sequential ventilation has certain difficulties, and sequential invasive-noninvasive ventilation on patients after tracheostomy is less common in practice. The present study aimed to investigate the feasibility of invasive-noninvasive sequential weaning strategy in patients after tracheostomy. METHODS: Fifty patients including 24 patients with withdrawal of mechanical ventilation (conventional group) and 26 patients with sequential invasive-noninvasive weaning by directly plugging of tracheostomy (sequential group) were analyzed retrospectively after appearance of pulmonary infection control (PIC) window. The analysis of arterial blood gases, ventilator-associated pneumonia (VAP) incidence, the total duration of mechanical ventilation, the success rate of weaning and total cost of hospitalization were compared between the two groups. RESULTS: Arterial blood gas analysis showed that the sequential weaning group was better than the conventional weaning group 1 and 24 hours after invasive ventilation. The VAP incidence was lowered, the duration of mechanical ventilation shortened, the success rate of weaning increased, and the total cost of hospitalization decreased. CONCLUSION: Sequential invasive-noninvasive ventilator weaning is feasible in patients after tracheostomy.

OBJECTIVETo observe the effect of Oxymatrine on left cardiac function and ventricular remodeling in rabbits after acute myocardial infarction.

METHODSLigation of the left anterior descending artery was adopted to establish acute myocardial infarction model, forty eight rabbits were randomized into the sham operation group, model group and Oxymatrine group. Eight models were successfully established in each group. the sham operation group and model group were given conventional feed. Oxymatrine were gavage administration 0.5 ml/100 g, once a day, lasted for 4 weeks. Respectively in postoperative week, and three weeks, to observe the Oxymatrine on cardiac output (CO), left ventricular end systolic pressure (LVESP), left ventricular end-diastolic pressure (LVEDP), left indoor pressure change rate peak (dp/dtmax)), and left ventricular cavity internal diameter (D), ventricular weight index (VWI), ventricular weight (VW).

RESULTSLeft ventricular anterior wall was from red to deep purple, electrocardiogram showed II guide ST-segment camber up ≥ 0.25 mv. Postoperative week in Oxymatrine group compared with model group, LVESP increased significantly (P < 0.01), LVEDP decreased obviously (P < 0.01); After three weeks in Oxymatrine group compared with model group, VW, VWI decreased (P < 0.05), D significantly reduced (P < 0.01); LVESP increased significantly (P < 0.01), LVEDP decreased obviously (P <0.01); dp/dt(max), CO increased (P < 0.05).

CONCLUSIONAfter acute myocardial infarction in rabbit Oxymatrine can improve the left ventricular reconstruction parameters, increase cardiac output, and improve cardiac function.

1 ? 25-dihydroxy-vitamin D3(1? 25 (OH)2 D3)induced differentiation of human promyelocytic leukaemia cells ( HL-60 ) into mature myeloid cells in vitro. The ratio of nuclei to cytoplasma decreased; Their nucleoli reduced; Cells became irrgular and extended the pseudopods. 1 ? 25 (OH ) 2 D3 caused significant increase of nitroblue tetrazolium ( NBT ) reduction and ?-non-specific acid esterase (?-NAE ) and acid phosphatase (ACP ) activities. These data and morphological characteristics suggest that HL-60 cells were conclusively identified as monocytes/macrophages. The histogram of DNA distribution ahylyzed by flow cytometry demonstrated G0 + G1 phase increased and S phase increased and S phase decreased remarkably after treatment with l?, 25 ( OH ) 2 D3 as compared with untreated cells.

Ameloblastic fibroma (AF) is a benign tumor, it is a true mixed tumor composed of neoplastic epithelium and mesenchymal. This tumor is rare, and it almost arises in the mandible. A 22-years old female patient referred AF in the maxillary was present. The tumor was asymptomatic, except the right facial bulge. The radiograph showed a well-circumscribed neoplasm with several low density cysts involving the right maxillary and ethmoid. The lesion was enucleated and the material was sent for histopathologic examination. Microscopically, it was composed epithelium and mesenchymal with histopathological diagnosis of ameloblastic fibroma.

Background Proliferative vitreo-retinal diseases include all the overly proliferative diseases of eyes.Many kinds of cytokines play important roles in their pathogenesis.Hypoxia-inducible factor 1α(HIF-1α)participates in the pathogenesis of a lot of ischemic diseases.HIF-1α may play an important role in the pathogenesis of proliferative vitreo-retinal diseases. Objective Present study was to observe the expression of HIF-1α in vitreous body in the eyes with proliferative vitreo-retinal diseases.The vitreous samples were collected during the vitrectomy from 71 eyes of 69 patients(experimental group)including 39 eyes with proliferative diabetic retinopathy(PDR)and 32 eyes with proliferative Vitreoretinopathy(PVR).Sixteen eyes of 16 patients as the cases control group,including 14 eyes with macular hole(MH)and 2 eyes with epiretinal macular membrane(ERM).What is more,there were 8 vitreous fluid samples of the normal control group.The concentrations of HIF-1α in vitreous body were detected by enzyme-linked immunosorbent assay(ELISA).The written informed consent was obtained from each patient before any medical procedure. Results The concentrations of HIF-1α in vitreous body in the eyes of experimental group,the cases control group and the normal control group were(294.08±2.97)、(260.41±8.29)、(16.38±3.56)mg/L respectively,showing a significant difference among the three groups(F=248.77,P=0.00).The concentrations of HIF-1α in vitreous body were obviously increased in the eyes of experimental group in comparison with the normal control group and the cases control group respectively(t=22.25,P=0.00;t=2.70,P=0.00 respectively).The concentrations of HIF-1α in vitreous body were increased in the eyes of the cases control group in comparison with the normal control group eyes(t=14.21,P=0.00).There was inferior correlation between the concentrations of HIF-1α in vitreous body in the eyes of experimental group and the course of ophthalmopathy. Conclusion Intravitreous HIF-1α level regulates in the eyes with proliferative vitreo-retinal diseases. Expression of HIF-1α in vitreous had inferior correlation with the course of ophthalmopathy. HIF-1α may play an important role in the pathogenesis of proliferative vitreo-retinal diseases.

Objective To explore the mechanism of cerebral infarction caused by hyperhomocystinemia.Methods A hundred and nineteen paitents with acute cerebral infarction were chosen for case group.According to their levels of plasm total homocystine,they were divided into two groups: hyperhomocystinemia group and nonhyperhomocystinemia group.Forty patents without cerebrovascular disease,hepatophy,nephrosis and thyroid gland disease were chosen as control subjects.Plasm levels of total homocystine,serum levels of MDA and IL-8 were measured respectively,their correlations were also studied.Results Plasma levels of tHcy(?mol/L)and serum levels of MDA(nmol/L)and IL-8 (ng/ml)showed a significant increase in case group(19.97,4.41?0.84,0.23?0.08)in comparison with control subjects(9.83,3.24?0.64,0.12?0.08),t values were 8.139,8.021,7.767 respectively(P
