To evaluate the neuroprotective effect of nerve growth factor ( NGF ) on acute angle-closure glaucoma patients after trabeculetomy.METHODS: Patients with viral keratitis who underwent trabeculectomy in treatment of acute angle - closure glaucoma in Xiamen Eye Center of Xiamen University from December 2011 to October 2013 were selected and completed the treatment, 61 eyes of 45 cases were followed up. The treatment group of 23 cases (32 eyes) with acute angle-closure glaucoma patients were treated by NGF gel for 3mo after trabeculetomy, while in the control group 22 cases (29 eyes) were treated by normal saline replaced NGF. All patients were followed up for at least 12mo, visual acuity, perimetry, retinal nerve fiber layer ( RNFL) thickness and cup/disc ratio of the patients were followed up during the treatment. The safety of topical use of NGF gel was also evaluated.RESULTS:ln all patients, the intraocular pressure ( lOP) was successfully controlled under 21mmHg and the visual acuity was markedly increased in the affected eye after trabeculectomy. Compared with control group, the postoperative lOP and visual acuity had no significant differences in treatment group (P>0. 05). The average light sensitivity of perimetry and mean defect were better than that in control group postoperative 6 and 12mo; The results of optical coherent tomography ( OCT ) and Heiderburg Retina Tomography ( HRT )-Ⅲ showed that RNFL thickness was significantly greater than that in control group, while cup/disc ratio significantly less than that in control group postoperative 6 and 12mo. Ocular surface damage, corneal endothelium to reduce and other eye complication were no observed in treatment group.CONCLUSlON:Acute angle-closure glaucoma treated by NGF gel after operation is effective and safe.

OBJECTIVETo evaluate the effects of prenatal stress on neurological functions after middle cerebral artery occlusion (MCAO) in adult offspring rats.

METHODSPregnant rats were randomly assigned to prenatal stress treatment, which was exposed to restraint three times daily in the last week of pregnancy, and no prenatal stress treatment. Adult male offspring rats were subjected to transient focal cerebral ischemia by MCAO. They were randomly divided into four groups: sham group, prenatal stress + sham group, MCAO group and prenatal stress + MCAO group (n = 10). After 24 hours of reperfusion, the neurological deficits were evaluated. The infarct size, cell apoptosis and expression of Caspase 3, cleaved Caspase 3 and Bcl-2 were detected.

RESULTSCompared with MCAO group, the neurological deficits, infarct size and apoptotic cells in prenatal stress + MCAO group were increased significantly (all P < 0.05). The expressions of Caspase 3 and cleaved Caspase 3 were much greater in prenatal stress + MCAO group than those of MCAO group, while the expression of Bcl-2 was significantly decreased in prenatal stress + MCAO group compared with MCAO group (all P < 0.05).

CONCLUSIONPrenatal stress might exacerbate neuroloeical deficits in the offspring rats after MCAO by increasing cell apoptosis.

Objective:To study the effect of electroacupuncture (EA) at the Pericardium Meridian on the heart function of volunteers with acute hypoxia, and to provide scientific evidence for the acupoints selection along the affected meridian in acupuncture-moxibustion therapy. Methods:Based on a self-control design, eighteen healthy volunteers were recruited in the study. Points from the Pericardium Meridian [Neiguan (PC 6), Ximen (PC 4), Quze (PC 3) and Tianquan (PC 2)], non-Pericardium Meridian point [Shousanli (LI 10)], non-meridian and non-acupoint points [1.0-1.5 cm lateral to Neiguan (PC 6) and Ximen (PC 4), respectively on both sides], and a blank control (only inhaling low-oxygen gas without EA stimulation) were selected to observe, once every week, 10 sessions in total, and only 1 acupoint was observed once. The volunteers inhaled low-oxygen gas mixture (10.8% O2 and 89.2% N2) for 30 min to imitate acute hypoxia. EA was conducted when the gas mixture was inhaled for 10 min and then lasted for 20 min; meanwhile, hemodynamic indexes such as cardiac output (CO), cardiac index (CI), systemic vascular resistance (SVR), systemic vascular resistance index (SVRI), left cardiac work (LCW), left cardiac work index (LCWI) and heart rate (HR) were recorded on a hemodynamic monitor. Results:EA at the acupoints of Pericardium Meridian significantly down-regulated the increased CO/CI, LCW/LCWI, and HR (P<0.05), and significantly up-regulated the decreased SVR/SVRI in hypoxia (P<0.05); EA at other meridian acupoints or at non-meridian and non-acupoint points didn't produce such effects. Conclusion: EA at the Pericardium Meridian can obviously improve the cardiac hyper-activation caused by acute hypoxia in healthy volunteers.

OBJECTIVETo establish a rapid method for detection of alpha-globin gene αααbased on droplet digital PCR (ddPCR) technique.

METHODSThe differential sequence between the X1 and Y1 box of α1 gene was selected as the amplicon of the target gene with β-actin as the reference gene. The specific primers and TaqMan probes were designed, and then a quantitative method for detecting the copy number was established based on ddPCR technique. The sensitivity and accuracy of the method were evaluated by detecting 28 samples of known genotypes and 60 clinical samples.

RESULTSThe ddPCR-based method accurately identified the genotypes of all the 28 samples with known genotypes and detected 5 cases of αα/αααfrom the 60 clinical samples, and the results were verified by MLPA. The sensitivity and accuracy of this method were both 100% for detecting alpha-globin gene ααα.

CONCLUSIONThis ddPCR-based method for detecting αααtriplet can be applied for population screening and in routine clinical molecular diagnosis with simple operation, rapid analysis and accurate results.

OBJECTIVETo study the clinical and pathologic characteristics of poorly differentiated cutaneous angiosarcoma of scalp.

METHODSEight cases of poorly differentiated cutaneous angiosarcoma of scalp were enrolled into this study. The clinical manifestations and histopathologic features were analyzed. Immunohistochemical study for CD31, CD34, factor VIII-related antigen, vimentin, AE1/AE3, CAM5. 2, epithelial membrane antigen and carcinoembryonic antigen was performed.

RESULTSThe mean age of the patients was 69 years. The male-to-female ratio was 5 : 3. The tumor manifested clinically as bruise-like lesion in early phase, indurated erythematous plaque accompanied by nodules, ulcerations and bleeding in advanced phase. Histologically, the tumor was composed of solid sheets of undifferentiated spindle cells which were not easily recognizable as vascular in origin. Nuclear atypia was always present. The tumor cells in all of the 8 cases strongly expressed CD31, factor VIII-related antigen and vimentin. Weak expression of CD34, AE1/AE3 and CAMS. 2 was noted in 2, 4 and 4 cases, respectively. The staining for epithelial membrane antigen, carcinoembryonic antigen and S-100 was negative. Conclusions Angiosarcoma needs to be excluded by histologic examination whenever bruise-like and erythematous lesions occurring on scalp skin of elderly patients. The endothelial origin of the tumor cells can be confirmed with immunostaining for CD31, CD34 and factor VIII-related antigen.

OBJECTIVETo observe the pregnancy outcome among patients with chronic myelogenous leukemia (CML) treated with tyrosine kinase inhibitors (TKIs).

METHODSData associated with pregnancy, delivery and neonate from the patients or patient's spouse who conceived while receiving TKIs were collected retrospectively.

RESULTSTwo young female patients (who had been on imatinib therapy for 90 and 91 months, respectively) and spouses of 10 male patients (involving 7 patients who had received imatinib for a median of 60 months and 3 who had received dasatinib for 2.5 months to 7 months, respectively) with median age of 33.5 years (range 26 - 46 years) conceived and gave birth to 12 babies. One woman took imatinib throughout her pregnancy except one month. The other one took imatinib throughout her pregnancy and had breast-fed while on imatinib therapy for nearly half a year postpartum. Among the 12 babies, one was born prematurely with low birth weight and hypospadias (surgical repair after birth), the others were all healthy with no congenital defects. The median age of the children at the date of this report is 17.5 months (range 3 to 101 months), and they all have a normal pattern of growth and development.

CONCLUSIONSConception among patients with CML while receiving TKIs may result in normal pregnancies. The possible effects of TKIs on birth abnormalities cannot be ruled out. It is recommended that childbearing female patients should be advised to practice adequate methods of contraception and should not breast-feed while on TKIs therapy. In cases of accidental pregnancy, risk/benefit evaluations must be carried out carefully on an individual basis. No special precautions apply for male patients being treated with imatinib.

OBJECTIVETo explore the relationship between serum apolipoprotein A5 (ApoA5) and lipid profile or high sensitive C-reactive protein (hs-CRP) in patients with acute coronary syndrome (ACS).

METHODSSerum apoA5 and hs-CRP levels were measured by ELISA and immunoturbidimetry in control subjects (n = 232), patients with stable angina (SA, n = 127), unstable angina (UA, n = 116) and acute myocardial infarction (AMI, n = 112). Triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were also measured.

RESULTSCompared with controls [(108.7 +/- 23.2) microg/L] and SA patients [(78.3 +/- 20.2) microg/L], serum ApoA5 level was significantly increased in UA [(340.6 +/- 63.5) microg/L] and AMI patients [(373.2 +/- 73.8) microg/L] (all P < 0.05). ApoA5 was positively correlated with TG (r = 0.63 and 0.67, respectively, all P < 0.05) and hs-CRP (r = 0.57 and 0.55, respectively, all P < 0.05) in UA and AMI patients but there were no significant correlations between ApoA5 and TC, HDL-C and LDL-C in ACS patients (all P > 0.05).

CONCLUSIONIncreased serum apoA5 level and the positive correlation between ApoA5 and serum TG and hs-CRP in ACS patients might reflect increased inflammation responses in ACS patients.

AIM:To investigate the role of microRNA-101-3p (miRNA-101-3p) on the proliferation, apopto-sis and invasion of gastric cancer cells and the possible regulatory mechanisms .METHODS: The expression of miRNA-101-3p in two kinds of gastric cancer cells and a gastric mucosal cell line was detected by real -time PCR.The miRNA-101-3p was overexpressed by Lipofectamine 2000 transfection with miRNA-101-3p mimics.The effects of miRNA-101-3p on cell cycle distribution and apoptosis were analyzed by flow cytometry .The effects of miRNA-101-3p on cell proliferation and migration abilities were detected by CCK-8 assay, trypan blue exclusion test and Transwell assay .The protein expression of enhancer of zeste homolog 2 ( EZH2) was determined by Western blot .RESULTS: The expression of miRNA-101-3p in gastric cancer cells was lower than that in gastric mucosal cells (P<0.05).The gastric cancer cell MGC-803 had the low-est expression level of miRNA-101-3p.The result of flow cytometry showed that the population of S phase was reduced , and the population of G0/G1 phase and the early stage apoptotic rate were increased after the expression of miRNA-101-3p was overexpressed (P<0.05).The results of CCK-8 assay, trypan blue exclusion test and Transwell assay showed that overex-pression of miRNA-101-3p significantly reduced the proliferation and migration abilities of gastric cancer cells (P<0.05). Overexpression of miRNA-101-3p decreased the protein level of EZH2 (P<0.05).CONCLUSION:miRNA-101-3p may suppresses the gastric cancer cell proliferation and migration , and promotes the gastric cancer cell apotosis by down-regula-tion of EZH2.

Objective To study the diagnostic values of X-ray,CT and MRI for the hip joint lesion of the patient with ankylosing spondylitis (AS).Methods Totally 180 AS patients underwent the examinations of X-ray,CT and MRI from January 2014 to December 2015,and the hip joint lesion,clinical features and the efficacies of the three imaging techniques were observed.Results The rates for positive findings were 69.44％,71.11％ and 72.22％ respectively by X-ray,CT and MRI,and more than 90％ patients had the lesions occurred at the bilateral hip joints simultaneously.Hip joint lesion of AS had the imaging features of bone marrow and joint space changes,which related to the disease progress closely.Early positive signs consisted of medial joint space narrowing by X-ray,rear joint space narrowing by CT as well as bone marrow fat deposition (BMFD) and bone marrow edema (BME) by MRI.Conclusion X ray,CT and MRI all gain their advantages when used to diagnose the hip joint lesion of AS.X-ray behaves well in early diagnosis of medial joint space narrowing,while have disadvantages in displaying soft tissues and minute structures when compared with CT and MRI.CT displays the minute structure of hip joint clearly,and is not so good at soft tissue resolution as MRI.MRI gains the highest resolution for displaying soft tissues in the three techniques,and can show BMFD,BME and etc which can not be revealed by X-ray and CT.
