Abstract?AlM:To compare the effects of different adjustable suture in glaucoma trabeculectomy on early tear film function.?METHODS:Sixty-eight cases of primary glaucoma ( 76 eyes) during January 2012 to June 2014 in our hospital were selected and divided into exposure conjunctival suture group ( 34 cases, 36 eyes ) and embedded conjunctival suture group ( 34 cases, 40 eyes ) according to treatment. Adjustable suture exposed conjunctival suture and embedding conjunctival suture was given to two groups, respectively. lntraocular pressure ( lOP ) before and after treatment 7, 14, 30d were observed and Schirmer test, tear break-up time, No Hikaru sensitivity and the occurrence of adverse reactions after treatment 1, 30d were recorded.?RESULTS: After the treatment, the mean lOP of two groups were decreased significantly ( P < 0. 05 ). The average lOP after treatment of 1d in the two groups were not statistically different (P>0. 05), after treatment 7, 14, 30d embedded conjunctival suture group was significantly higher than that of exposure conjunctival suture group ( P<0. 05). After 1d of treatment, Schirmer test, tear break-up time, No Hikaru sensitivity of two groups compared no significant difference (P<0. 05). After treatment 7, 14, 30d embedded conjunctival suture group Schirmer test, tear break- up time, was significantly superior to expose conjunctiva suture group (P<0. 05). The 30d package after treatment of conjunctival suture group buried adverse reaction rate was significantly lower than that of exposed conjunctival suture group (P<0. 05).? CONCLUSlON: Trabeculectomy operation with adjustable thread embedding conjunctival suture has few effects on the tear film function in patients with early postoperative complications, lower, and operation effect is better than that of exposed conjunctival suture.

OBJECTIVETo study the clinical manifestations and neuroimaging characteristics of pediatric moyamoya disease.

METHODSThe clinical data of 17 children with moyamoya disease were retrospectively studied.

RESULTSThe onset age was between 3 and 14 years. The main clinical manifestations included motor weakness of extremities or hemiplegia, sensory disturbance and headache. Cranial CT or/and MRI examinations predominately showed cerebral infarct. Magnetic resonance angiography (MRA) and digital subtraction angiography (DSA) showed stenosis or occlusion at the terminus of the siphon portions of internal carotid arteries and proximal portions of anterior or middle cerebral arteries, and abnormal vascular networks at the base of brain.

CONCLUSIONSCerebral ischemia is main clinical manifestations in children with moyamoya disease, presenting motor weakness of extremities or hemiplegia, sensory disturbance and headache. DSA is essential to the diagnosis of the disease.

Objective To investigate the neuroprotective effect of [Gly14]-humanin (HNG) in rats with intracerebral hemorrhage (ICH). Methods Thirty healthy male SD rats were randomly divided into 3 groups, namely the sham operated group (10 rats) with needle insertion only, ICH model group (10 rats) with injection of autologous whole blood into the right caudate nucleus, and HNG treatment group (10 rats) with HNG injection into the lateral cerebral ventricle after simulated ICH as in the model group. The changes in the glial cells and cell apoptosis around the hematoma were detected 72 h after the operation. Results The astrocytes and microglial cells in rats receiving HNG injection into the cerebral ventricles showed smaller cell size and shorter and thinner cell processes than those in ICH model group. The numbers of cells positive for glial fibrillary acidic protein (GFAP) and OX42 and the apoptotic cells (as found by TUNEL assay) around the hematoma were significantly reduced in comparison with those in the ICH model group (P<0.05), but still remained significantly higher than those in the sham-operated group (P<0.05). Conclusion HNG can ameliorate the inflammatory response occurring in and around the hematoma and provide some neuroprotection in rats with ICH.

OBJECTIVETo study the effect of pulchinenoside (PULC) in modulating SFRP2 expression in fibroblast-like synoviocytes (FLS) of rheumatoid arthritis (RA) model rats.

METHODThe effect of PULC in treating RA rats was evaluated by rat arthritis score and paw swelling score. The inhibitory effect of PULC on FLS proliferation was detected by MTT reagent. The effects of PULC gavage treatment in modulating gene expression of FLS SFRP2, critical gene beta-catenin of Wnt pathway and downstream effector genes C-myc of of Wnt pathway were detected by RT-PCR and Western blotting.

RESULTPULC had a significant effect in treating RA rats and that SFRP2 expression was down-regulated in FLS. After PULC gavage treatment, FLS SFRP2 expression was obviously up-regulated, whereas beta-catenin and C-myc gene expressions were significantly down-regulated.

CONCLUSIONPULC can inhibit abnormal proliferation of synovial membrane by modulating Wnt pathway of RA rats.

OBJECTIVETo investigate the changes and effects of arginine vasopressin (AVP) in patients with acute traumatic subarachnoid hemorrhage (tSAH).

METHODSThe plasma and cerebrospinal fluid (CSF) level of AVP, and intracranial pressure (ICP) were measured in a total of 21 patients within 24 hours after tSAH. The neurological status of the patients was evaluated by Glasgow Coma Scale (GCS). Correlation between AVP and ICP, GCS was analyzed respectively. Meanwhile, 18 healthy volunteers were recruited as control group.

RESULTSCompared with control group, the levels (pg/ml) of AVP in plasma and CSF (x+/-s) in tSAH group were significantly increased within 24 hours (38.72+/-24.71 vs 4.54+/-1.38 and 34.61+/-21.43 vs 4.13+/-.26, P less than 0.01), and was remarkably higher in GCS less than or equal to 8 group than GCS larger than 8 group (50.96+/-36.81 vs 25.26+/-12.87 and 44.68+/-31.72 vs 23.53+/-10.94, P less than 0.05). The CSF AVP level was correlated with ICP (r eqaul to 0.46, P less than 0.05), but no statistically significant correlation was found between plasma AVP, CSF AVP and initial GCS (r equal to -0.29, P larger than 0.05 and r equal to -0.32, P larger than 0.05, respectively). The ICP (mm Hg) in tSAH patients was elevated and higher in GCS less than or equal to 8 group than in GCS larger than 8 group (25.9+/-9.7 vs 17.6+/-5.2, P less than 0.05).

CONCLUSIONOur research suggests that AVP is correlated with the severity of tSAH, and may be involved in the pathophysiological process of brain damage in the early stage after tSAH. It seems that compared with the plasma AVP concentration, CSF AVP is more related to the severity of tSAH.

OBJECTIVETo investigate the abnormal abundances of calcium regulatory proteins in rabbit myocytes with failing hearts.

METHODSSixteen rabbits were divided into two groups: 8 rabbits with heart failure induced by volume plus pressure overload and 8 sham-operated animals. The hemodynamic parameters and cardiac structure and function were detected via catheterization and echocardiography respectively. L-type calcium channel (LTCC), Ryanodine receptor 2 (RyR2), Sarcoplasmic reticulum Ca(2+)-ATPase (SERCA2a), and Na(+)-Ca(2+) exchanger (NCX) protein abundances were determined by Western blot analysis.

RESULTSThe ratio of left ventricular mass to body weight, heart rate and left ventricular end diastolic pressure in heart failure rabbits were significantly increased compared with sham-operated rabbits (P < 0.01), but their left ventricular shorten fraction [(21.3 +/- 4.00)% vs. (36.5 +/- 1.36)%] and ejection fraction (0.45 +/- 0.07 vs. 0.70 +/- 0.02) were decreased (P < 0.01). In heart failure rabbits, the abundances of LTCC and RyR2 were significantly decreased (R(LTCC/actin): 0.287 +/- 0.029 vs. 0.624 +/- 0.009; R(RyR2/actin): 0.106 +/- 0.001 vs. 0.203 +/- 0.011; P < 0.01), whereas the expressions of SERCA2a and NCX were markedly increased (R(NCX/actin): 0.497 +/- 0.015 vs. 0.221 +/- 0.014; R(SERCA2a/actin): 0.611 +/- 0.036 vs. 0.433 +/- 0.008; P < 0.01).

CONCLUSIONSReductions of LTCC and RyR2 might contribute to risk factors of systolic dysfunction in failing hearts. In early stage of heart failure, upregulated SERCA2a and NCX protein levels may be helpful for maintaining cardiac performance.

BACKGROUND AND OBJECTIVECytokine-induced killer (CIK) cells and autologous dendritic cells-CIK (DC-CIK) cells co-cultured with autologous dendritic cells (DCs) and CIK cells are commonly used for immunotherapy recently. We compared the anti-tumor immune response of CIK cells, autologous DC-CIK cells, and semi-allogeneic DC-CIK cells to explore a more effective anti-tumor adoptive immunotherapy approach.

METHODSPeripheral monocytes were isolated from patients with renal carcinoma, lung cancer, or maxillary squamous cell carcinoma and their healthy adult children. Isolated cells were cultured and induced as DCs and CIK cells in vitro. CIK cells from patients were co-cultured with autologous DCs and DCs from their children respectively, generating DC-CIK cells and semi-allogeneic DC-CIK cells. The anti-tumor activities of autologous CIK cells, autologous DC-CIK cells, and semi-allogeneic DC-CIK cells were measured by LDH assay. Intracellular staining was used to test the secretion of cytokines. Flow cytometry was applied for detecting the phonotype changes of these three types of cells. Cell proliferation and cell apoptosis were detected by 5,6-carboxyfluorescein diacetate succinimidyl ester (CFSE) and Annexin V/PI respectively.

RESULTSCompared with autologous CIK cells and DC-CIK cells, semi-allogeneic DC-CIK cells significantly enhanced the anti-tumor activity and IFN-gamma secretion, reduced IL-4 secretion, increased the ratio of CD3(+)CD56(+) cells and CD3(+)CD8(+) cells, decreased the number of CD4(+)CD25(+) cells, promoted cell proliferation, and lessened cell apoptosis.

CONCLUSIONSSemi-allogeneic DC-CIK cells had a stronger anti-tumor effect than did autologous CIK cells and DC-CIK cells. Our results provided experimental evidence for clinical application of DC-CIK cells.

This study was aimed to investigate the radioprotective effects of recombinant human interleukin-12 (rhIL-12) on monkey hematopoietic system, and to provide experimental evidence for future clinical prophylaxis and treatment for patients who suffered from acute radiation syndrome. In in vitro study, the effect of rhIL-12 in different concentrations (0, 1, 5, 25, 125 and 625 ng/ml) on colony forming capacity of human or monkey bone marrow-derived mononuclear cells was examined in methylcellulose H4434 medium. In in vivo study, the acute radiation syndrome model was established in 11 Rhesus monkeys which received lethal total body irradiation by 6 Gy (60)Co γ in single time irradiation. The irradiated monkeys were randomly divided into 3 subgroups: control group (n = 4) which received subcutaneous PBS injection, rhIL-12 single-dose group (n = 3) which received subcutaneous single injection of rhIL-12 (4 µg/kg) at 2 h after irradiation, and multiple-dose group (n = 4) which received subcutaneous injection of rhIL-12 (1 µg/kg per injection) at 2 h, day 3, 6 and 9 after irradiation respectively. Peripheral blood cells were counted before and after irradiation every other day. The survival status of animals were observed daily. In vitro test results showed that different concentrations of rhIL-12 obviously promoted human and healthy monkeys' bone marrow mononuclear cells to form various hematopoietic progenitor cell colonies, especial CFU-E and CFU-GM. All animals in control group died within 22 d after lethal total body irradiation, average survival time was (20.3 ± 1.2) d. Only one monkey in multiple-dose group died due to anemia on day 17. All monkeys in single-dose group survived. Compared with control group, rhIL-12-administrated monkeys' white blood cell count, hemoglobin level, platelet and reticulocyte counts showed faster recovery from high dose radiation. It is concluded that the rhIL-12 treatment can promote the bone marrow hematopoietic stem/progenitor cell colony formation in vitro and protect lethally-irradiated monkeys. There is an obvious therapeutic effect of rhIL-12 on monkeys suffered from bone marrow failure caused by severe acute radiation exposure.
