AlM: To observe the postoperative intraocular pressure ( lOP) and operation safety in the eyes of the neovascular glaucoma pateints treated by intraocular cyclophotocoagulation which needed vitrectomy at the same time.
METHODS: A total of 12 neovascular glaucoma cases ( 14 eyes ) secondary to diabetic retinopathy, retinal detachment surgery and trauma were reviewed in our study. This procedure mainly used intraocular photocoagulation catheter to highlight the ciliary processes until the ciliary became white atrophy or plosion after vitreous surgery treatment. The intraocular photocoagulation catheter was performed at a power of 300-500mW, for a duration of 0. 1-0. 2ms. Postoperative follow-up was at least for 6mo. The observation of 14 postoperative neovascular glaucoma was performed at 1wk, 1, 6mo observing the lOP and complications.
RESULTS:lOP of the 11 eyes was significantly declined and controlled in normal. After cyclophotocoagulation, average lOP at 1wk was 16. 7±14. 4mmHg, 15. 7±8. 8mmHg at 1mo and 12. 9±4. 5mmHg at 6mo, which compared with untreatment ( 39. 6 ± 10. 0mmHg ) was statistically significant different (P<0. 01). ln follow up time 3 cases were relapsed which were supplied with transscleral or endoscope cyclophotocoagulation. During the follow-up period no endophthalmitis and complications such as eyeball atrophy were found.
CONCLUSlON: The intraocular cyclophotocoagulation and vitrectomy simultaneously can deal with the primary disease and secondary neovascular glaucoma. The operation can be accurately performed under direct cyclophotocoagulation and it is a safe and effective way for neovascular glaucoma which needs vitreous surgery.

Thirty-two patients with comminuted proximal humerus fractures(Neer Ⅲ or Ⅳ) were admitted to Department of Orthopedics,First Hospital of Jilin University from March 2001 to April 2006.The patients consisted of 19 males and 13 females,aged 19-70 years,including 15 of 19-49 years and 17 of 50-70 years.All patients underwent treatment of cloverleaf plate-screw fixation.During the follow-up for 8 months,union time and scores from Constant & Murley functional scale were similar between male and female groups.Compared with patients aged 50 years,and the scores from Constant & Murley functional scale were significantly lower(P 50 years old is relatively longer with unfavorable functional recovery in the shoulder joint.

Objective To investigate the expression of Toll-like receptor 4 (TLR4) and myeloid derived suppressor cells(MDSC) in bone marrow cells in children with acute myeloid leukemia (AML),and to detect its relationship with the clinical features,the effect of chemotherapy and prognosis.Methods Twenty-nine cases of children with AML were collected from June 2013 to March 2014 in People's Hospital of Wuhan University,in which 11 cases of low-risk group,10 cases of middle-risk group,8 cases of high-risk group;and 17 cases of non blood disease was as the control group.The expressions of TLR4 and MDSC were detected by using reverse transcription-polymerase chain reaction (RT-PCR),Western blot methods,immunohistochemical staining,and flow cytometry,respectively,in the bone marrow cells of 29 children with AML.Results The mRNA and protein expression of TLR4 in the initial treatment group was higher than those in the complete remission group(t =3.092,3.393,all P ＜ 0.05).The mRNA and protein expression of TLR4 in the relapse group was higher than those in the complete remission group(t =4.013,4.279,all P ＜ 0.05).The positive expression rates of MDSC in the above 3 groups were (29.77 ± 1.39) ％,(5.19 ± 0.65) ％,(38.62 ± 3.54) ％,respectively,compared with the control group [(1.32 ± 0.27) ％] and there was significant difference(all P ＜0.05).The positive expression rates of TLR4 and MDSC in the initial treatment group,relapse group and complete remission group were significantly higher than those in the control group,with significant differences (initial treatment group TLR4:t =3.559,P ＜ 0.05;MDSC:t =3.727,P ＜ 0.05;relapse group TLR4:t =4.043,P ＜ 0.05;MDSC:t =4.125,P ＜ 0.05;complete remission group TLR4:t =2.798,P ＜ 0.05;MDSC:t =3.469,P ＜ 0.05).Pearson rank correlation analysis showed that there was a positive correlation between the expression of TLR4 and MDSC (r =0.673,P ＜0.01).Conclusions The expressions of both TLR4 and MDSC play an important role in onset,progression,curative effect and prognosis in children with AML,and the two may play an importment role in synergistic effect.

Objective To investigate the molecular mechanism underlying lymphocyte functionassociated antigen-1 (LFA-1) / intercellular adhesion molecule-1 (ICAM-1) mediated anti-neoplastic effects of cytokine induced killer (CIK) cells. Methods Lymphocytes isolated from peripheral blood of children leukemia were induced with interferon-gamma (IFN-y), anti-CD3 monoclonal antibody (CD3McAb) and interleukin-2 (IL-2) and co-cultured with dendrite cells (DC) to generate DC-CIK cells. When treated with LFA-1 monoclonal antibody, cytotoxicity of DC-CIK cells against leukemia cell lines was measured by the MTT assay, while RT-PCR and Western blotting were used to determine mRNA and protein expressions of GATA-3 and T-bet in DC-CIK cells, respectively. IL-12, IFN-γ and tumor necrosis factor-α (TNF-α) levels released by DC-CIK cells were quantified by ELISA. Results Induced DC-CIK cells were regular, round and transparent with variable cell volume and cellular aggregation. When treated with mouse anti-human LFA-1 monoclonal antibody, the cytotoxicity decreased mostly towards B95 cells under administration of 20 μg/ml LFA-1 monoclonal antibody in comparison with the control group(t =10.138, P ＜0.05). It led to a highest elevation of GATA-3 mRNA and protein levels (t =16.386, P ＜ 0.05; t =22.652, P ＜ 0.05) and a most decrease of T-bet mRNA and protein levels (t =17.728, P ＜0.05; t =17.452, P ＜0.05) under 20 μg/ml LFA-1 monoclonal antibody in B95 cells group in comparison with the control group. The expression levels of IL-12,IFN-γ, and TNF-o in supernatant were the lowest under 20 μg/ml LFA-1 monoclonal antibody in B95 cells group in comparison with the control group (t =21.621, P ＜0.05; t =13.739, P ＜0.05; t =15.278, P ＜0.05).Conclusion GATA-3 and T-bet were implicated in the LFA-1/ICAM-1 mediated anti-neoplastic effects of DC-CIK cells via activation of the Th1 pathway, with high secretion of Th1 cytokines, such as IL-12, IFN-γ and TNF-α.

Objective To detect the levels of plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) and investigate its relationship with liver function, ascites and heart structure in patients with liver cirrhosis. Methods The levels of plasma NT-proBNP and various clinical and biochemical parameters were determined in 60 patients with liver cirrhosis and 30 healthy controls. Meanwhile Child-Pugh liver function was classified. All people underwent color Doppler echocardiography. Results The level of plasma NT-proBNP was significantly elevated in patients with liver cirrhosis [(38.63±36.05)pmol/L], compared with that of the controls [(7.50±8.25)pmol/L],P<0.01. There was no significant difference in different Child-Pugh class and aseites amount of liver cirrhosis. E/A < 1 and E wave decelerate time (EDT) was in-creased in liver cirrhosis. Conclusion The levels of plasma NT-proBNP in liver cirrhosis are significantly elevated, and related to early impairment of diastolic function. But it does not correlate with liver function and aseites.

BACKGROUND:The previous researches indicate that, shock waves can enhance the proliferation of T-cells and the expression of interleukin (IL)-2 through a mechanism that involves p38 mitogen activated protein kinase (MAPK)activation.OBJECTIVE: To investigate if adenosine triphosphate (ATP) release is an underlying mechanism through which low-density shock waves (LDSWs) augment T-cell function.DESIGN: Controlled repetitive measurement by groups, taking cells as subject.SETTING: Department of Orthopedics, the First Hospital of Jilin University.MATERIALS: KDE-2001 Extracorporeal Shockwave Lithotripter (Beijing Zhongke Jian An Meditechs Co., Beijing, China).p38 MAPK inhibitor SB203580 1 mg (BioSource Inc., Camarillo, CA); p38 MAPK kit for detecting phosphorylation (Cell Signaling Technology, Inc. U.S.A.); P2 receptor inhibitor suramin 50 mg (BIOMOL Research Laboratories Inc., PA) was prepared into 0.02 mol/L solution by 1.749 2 mL IMDM. ATP enzyme: apyrase 200 U (Sigma, U.S.A.); P2X7 receptor antagonist KN-62 (BioSource Inc., Camarillo, CA); ATP Bioluminescence Assay Kit CLS Ⅱ (Roche Diagnostics GmbH,Mannheim, Germany).METHODS: The experiment was carried out in the Orthopedic Laboratory of the First Clinical Hospital in Jilin University from January 2005 to December 2006. ①An Extracorporeal Shockwave Lithotripter (at 7 kV generator voltage, 0.3 μF capacitance, 23 MPa positive pressure, 0.18 mJ/mm2 energy flux density) was applied for LDSWs treatment ranging from 50 to 400 impulses. ②ATP release into the culture supernatant from Jurkat T-cells or human peripheral blood mononuclear cells (PBMCs) was determined with a specific ATP Bioluminescence Assay Kit. ③Negative control group excluded antagonist or inhibitor. Human PBMCs were used to determine the effect of LDSWs on activated T-lymphocyte proliferation. Human Jurkat cells were used to study the effects of LDSWs on IL-2 expression. Expression and phosphorylation of p38 MAPK in Jurkat T-cell were measured by Western Immunoblotting with anti-p38 MAPK antibodies and anti-p38 MAPK phospho-specific antibodies that recognized the phosphorylation (on Thr180/Tyr182).MAIN OUTCOME MEASURES: extra-cellular ATP release, IL-2 expression in cell suspension, cellular proliferation and the phosphorylation of p38 MAPK.RESULTS: ①ATP release under the condition without LDSWs was obviously lower than that with LDSWs of 100, 150,200, 250, 300, 360 and 400 impulses (P ＜ 0.01), and ATP release increased with the LDSWs impulse.②Compared with negative control group, the additions of apyrase, KN-62 or suramin attenuated the 3H-TdR incorporation of the phytohemagglutinin-stimulated PBMCs or CD3/CD28-stimulated Jurkat T-cells, which were effected with LDSWs of 100,150, 200, 250, 300, 330 impulses at 0.18 mJ/mm2 (P＜ 0.01). IL-2 expression in the cellular supernatant was also significant increased (P ＜ 0.01). ATPase, KN-62 or suramin all decreased the effect of LDSWs on p38 MAPK of Jurkat T-cells.CONCLUSION: ①LDSWs deform cellular membranes but have no effect on organelle, which results in ATP release from Jurkat cells. Exogenous ATP release activates P2X7 receptor and p38 MAPK, and increases IL-2 expression. LDSWs enhance T-cell proliferation and IL-2 expression through a mechanism that involves ATP release, P2X7 receptor and phosphorylized p38 MAPK activation. ②The release of ATP plays a key role in the mechanism through which LDSWs regulate the function of T cells.
