Objective To explore the effects of vitrectomy on neovascular glaucoma combined with vitreous hemorrhage. Methods Seven eyes of 7 patients with neovascular glaucoma combined with vitreous hemorrhage underwent vitrectomy combined with phacoemulsification, panretinal photocoagulation, and trabeculectomy. The preoperative visual acuity ranged from light perception to 0.2, and the mean preoperative intraocular pressure was 54 mm Hg (38-64 mm Hg)(1 mm Hg=0.133 kPa). The mean follow-up was 8 months (6-15 months). Results The postoperative visual acuity ranged from light perception to 0.4, and the mean postoperative intraocular pressure was 17 mm Hg (10-30 mm Hg) which was significantly lower than preoperative one ( P

One child was hospitalized because of repeated cough and sputum. The biopsy diagnosis in local hospital was cystic lymphangioma in retropharyngeal space. We carried out transoral incision and drainage by catheter under general anesthesia. Put into the surgical cavity a suction drainage tube, and injected 5 mg dexamethasone and 8mg Bleomycin. He had nasogastric liquid diet after operation. We removed the suction drainage tube two weeks later. No recurrence was found following up over two years.

OBJECTIVETo investigate the effect of Actinidia chinensis Planch polysaccharide (ACPS) on the growth and apoptosis of human gastric cancer SGC-7901 cells, and to explore the effect of SGC-7901 cells on p-p38 expression.
METHODSThe inhibition rates at different concentrations of ACPS on SGC-7901 cells at 24, 48, and 72 h were detected using CCK-8 method. Apoptosis ratios in SGC-7901 were determined by flow cytometry after 48-h treatment of different concentrations of ACPS. The expression of pro-caspase-9, PARP, and p-p38 in SGC-7901 cells after treated by different concentrations of ACPS was detected using Western blot. The expression of pro-caspase-9, PARP, and p-p38 was detected after SGC-7901 cells were pre-treated by p38 specific inhibitor.
RESULTSCompared with the control group, the optical density of SGC-7901 cells decreased after treated by 1, 2.5, 5, and 10 mg/mL ACPS (P < 0.05). Meanwhile, the longer the acting time, the lower the optic density (P < 0.01). IC50 was 7.43 mg/mL at 24 h; 3.88 mg/mL at 48 h, and 1.32 mg/mL at 72 h respectively. ACPS suppressed the protein expression of pro-caspase-9 (P < 0.01) and up-regulated the expression of PARP (89KD) (both P < 0.01). Further study showed that the protein expression of p-p38 was up-regulated in SGC-7901 cells treated by ACPS of different concentrations at 24 h (P < 0.05). The expression of phosphorylation p38 and the ACPS induced apoptosis of SGC-7901 cells could be inhibited after treated by specific inhibitor for 2 h.
CONCLUSIONSACPS could inhibit the growth of SGC-7901 cells and induce apoptosis. The underlying mechanism of inducing apoptosis was partially due to activating the p38MAPK path and further activating Caspase9 and PARP, finally leading to cell death.

ObjectiveTo investigate the value of urinary BNP for diagnosis of chronic heart failure (CHF). MethodsThe levels of Urinary BNP and plasma BNP were measured by microparticle enzyme immunoassay (MEIA) in 83 patients with CHF and 30 control subjects. The heart function was classified according totheNYHAcriteria. Leftventricularejectionfractions(LVEF)weremeasuredby echocardiology. ResultsThe level of urinary BNP in patients with CHF was[90. 0(38. 3 -209. 5 )]ng/L and the level of plasma BNP was[680. 0 ( 289. 7 - 1543.5)]ng/L, both of them were much higher than those in healthy subjects,[17. 0 ( 13.0 - 33. 0)]ng/L and[84. 5 ( 56. 0 - 158.0 )]ng/L, respectively (P<0. 01 ). The concentrations of urinary BNP increased gradually with more severe symptoms ( NYHA cl ass Ⅰ -ⅣV ). The level of urinary BNP was positively correlated with NYHA class ( r = 0. 742, P < 0. 01 )and the level of plasma BNP (r =0. 842,P <0. 01 ) while negatively related with LVEF (r = -0. 801 ,P <0. 01 ). The level of urinary BNP in patients with LVEF < 40% was[143.0 ( 85. 0 - 258.0)]ng/L , which was much higher than that in patients with LVEF≥40% ,[31.5( 17.3 -38. 8)]ng/L, (P <0. 01 ). At a decision threshold of 36. 5 ng/L, the urine BNP assay demonstrated a clinical sensitivity and specificity of 84% and 80% ,respectively. In this study,the area under the curve(AUC) was 0. 905. ConclusionUrinary BNP is a new candidate marker for the diagnosis of CHF,it provides a similar accuracy with plasma BNP.

Objective To investigate the amounts of endothelial progenitor cells(EPCs)in peripheral blood of patients with proliferative diabetic retinopathy(PDR).Methods Forty patients with PDR(PDR group),thirty patmnts with type 2 diabetes mellitus(DM)without DR(DM group),and twenty agematched normal subjects(control group)were enrolled in this study.Blood samples were treated bv repeated centrifugation and stained with monoclonal antibodies.At least 2 × 105 cells were analyzed bv flow cytometry.EPCs were identified by CD34 and CD133 antibody.The correlation between EPCs numbers and DR duration,glycosylated hemoglobin,serum lipids was analyzed.Results The number of EPCs in PDR,DM and control group were(49±12)、(35±11)、(90±25)cells/ml respectively,the difference was statistically significant(F=56.260,P=0.000).There was a positive correlation between EPCs numbers and DR duration(r=0.564,P<0.05).However there was no correlation between EPCs numbers and glycosylated hemoglobin(r=-0.170,P>0.05)or triglyceride levels(r=0.261,P>0.05).Conclusions The number of EPCs in peripheral blood of PDR patients was decreased. EPCs might play an important role in the pathogenesis of PDR.

Objective To study the effects ofautologous bone marrow mononuclear cells (BMMCs)transplantation during coronary artery bypass gafting (CABG) on myocardial infarct size. Methods Forty myocardial infarction patients diagnosed by coronary angiography (CAG) and SPECT and confirmed at surgery were enrolled and randomly assigned CABG alone (group Ⅰ) or CABG with intramyocardial or intracoronary injection of autologous BMMCs (group Ⅱ), 20 cases in each group. Baseline and followed up evaluations included SPECT and NYHA-FC before and after 6 months operation, recorded the major adverse cardiac events (MACE) at the same time. The number of autologous BMMCs injected was (6.84 ± 2.88) ×107 in group Ⅱ. Results There was no procedure-related complication during 6 months followed up in all patients. After 6 months operation,left ventricular ejection fraction in group Ⅱ was significantly higher than that in group Ⅰ [(57.40 ±5.21)% vs. (50.75 ±5.88)%,t =3.79,P<0.05],NYHA-FC in group Ⅱ was significantly improved than that in group Ⅰ [(1.30 ± 0.47) grades vs. (1.85 ± 0.59) grades, t = 3.27, P <0.05],SPECT showed myocardial infarct size in group Ⅱ was significantly lower than that in group Ⅰ[(14.57 ±5.20)% vs. (20.45 ±5.18)% ,P <0.05]. Conclusion Autologous BMMCs transplantation during CABG is safe and feasible, which can reduce the myocardial infarct size in patients with myocardial infarction.
