AIM:To analyze relevancy between the changes of the retinal thicknesses of children's anisometropic amblyopic macular at Area A1 before and at the end of amplyopia cure and amplyopia cure effect.
METHODS: Through randomly selecting 30 cases ( 60 eyes) of anisometropic amblyopic children as test group and 29 cases ( 58 eyes ) of children with normal vision after the vision correction as control group, the changes of the retinal thicknesses of macular of the test group and the control group at Area A1 by OCT-3 was observed dynamically and analyzed.
RESULTS: Compared with first diagnosis, the comparative difference of retinal thicknesses of macular at Area A1 in control group at 3, 6mo has statistical significance. The test group was divided into amblyopia group and non-amblyopia group. There has statistical significance for the comparative difference between the retinal thicknesses of macular centre at 3, 6mo and the first diagnosis in the non - amblyopia group, the amblyopia group was divided into the invalid cure group, progress group and the cured group according to amblyopic cure effect. Compared with first diagnosis, there is no statistical significance of macular at Area A1 in invalid cure group and progress group at 3, 6mo, and in the cured group at 3mo, but in the cured group at 6mo has statistical significance.
CONCLUSION: There is a certain relationship between the changes of retinal thicknesses of macular of children with anisometropic amblyopic at Area A1 before and at the end of amblyopia treatment and amblyopia cure effect. OCT is a kind of objective auxiliary test method and provides new clues for amblyopia research.

Objective To observe the occurrence of vascular calcification in maintenance hemedialysis (MHD) patients. Method Sixty-nine MHD patients were enrolled in this study. Vascular calcification was evaluated by plain X-my films of chest, upper and lower extremites. Analyzed the relationship of vascular calcification and cardiovascular disease. Results Vascular calcification on X-ray films presented in 38 cases (55%). Of the 23 cases with calcification on arteries of extremites, 14 cases were found to have both intimal calcification and medial calcification. Patients with vascular calcification were older. Ischemic heart disease and cardiac failure appeared more frequently in the patients with vascular calcification. Conclusions Both intimal calcification and medial calcification are frequently found in the MHD patients. Vascular calcification is probablly associated with cardiovascular disease in MHD patients.

Objective To study the mandibular anterior alveolar morphological characteristics of skeletal ClassⅢmalocclusion patients by CT quantitative research , which can provide guidances and indications for clinical skeletal Class Ⅲmalocclusion treatment and prevent iatrogenic complications , such as rootabsorption. Method 25 skeletal Class Ⅲ malocclusion patients during thepostpubertal were selected , three-dimensionalspiralCTscanning was applied to measure cortical and cancellousbonethickness around 6 mandibular incisors for analyzing the relationship between the bone mass and its anatomyaround the mandibular incisors roots. Results (1) The bone thickness around the lower anterior homonym teeth was basically symmetric in the skeletal Class III malocclusion. The labial thickness is a little less than the lingual side , gradually thickening along the root apical direction; (2) The area of mandibular incisors was inhomogeneous , and the 1/2 regional cancellous bone thickness of mandibular incisors was often lacked. Conclusion (1) The synchronous compensation of the teeth and alveolar bone is the significant feature of the skeletal Class Ⅲ malocclusion. (2) The responding regions ofthe alveolar bone in the 1/3 labial-cervical and root-tip may be the sensitive areas during the orthodontic treatment.

Ginseng and its effective components are famous for their influence to enhance human immunity, regulate endocrine and antioxidant action. However, the different effects of different components are not clear. In this study, Wistar rats were used to study the effects of main components of ginseng, including total ginsenoside, panaxadiol saponins, panaxtrol saponin and ginseng polysaccharide. The results showed that the effects of panaxadiol saponins and ginseng polysaccharide on improving animal immune organ weight, plasma interleukin 2 (IL-2), interleukin 6 (IL-6), plasma gamma-interferon (IFN-γ), tumor necrosis factor alpha (TNF-α) were better than that of the other groups. Total ginsenoside and panaxtrol saponin can effectively increase the concentration of spleen NK cells (NKC) while panaxadiol saponins and ginseng polysaccharide can significantly increase the concentrations of rat plasma adrenocorticotrophic hormone (ACTH), corticosterone (CORT) and thyroid stimulating hormone (TSH). As for the effect of increasing organization nitric oxide (NO) and superoxide dismutase (SOD), glutathione (GSH) and malondialdehyde (MDA), total ginsenoside is better than that of other groups. In brief, different components in ginseng possess different effects on enhancing immunity, regulating endocrine and resisting oxidation. Panaxadiol saponins and ginseng polysaccharide are better in enhancing immune, and total ginsenoside shows advantages in resisting oxidation and stress.

Objective To study the effect of granulocyte-macrophage colony-stimulating factor(GM-CSF)on angiogenesis of rat with acute myocardial injury induced by isoproterenol(Iso). Methods A total of 60 adult male Wistar rats were randomly divided into 3 groups: normal control group, GM-CSF pretreatment group (GM-CSF group), and lso injury group, 20 rats in each group. GM-CSF group was administered recombinant human(rh)GM-CSF(5.0 μg/kg), through tail intravenous injection once a day for three days. Then the GM-CSF group and the Iso injury group were anesthetized by intraperitoneal injection of lso( 15.0 mg/kg) once a day for three days. The same dose of saline was administered in the same way to the control rats. Ten days after injection, pathological changes of myocardial damage and infarct area were examined by immunohistochemistry. The mRNA expression levels of polypeptide antigen (CD34), vascular endothelial growth factor (VEGF) and its receptor KDR/flk- 1 were measured by RT-PCR. Results The difference of myocardial necrosis area between groups was statistically significant(F=10.07, P < 0.01), in which GM-CSF group[(37.37 ± 12.98)%] was significantly less than Iso injury group[(45.51 ±14.96)%, P < 0.05]. The difference of myocardial neovascularization density index of rats between groups was statistically significant ( F = 25.54, P < 0.05 ), in which GM-CSF group [(3980.05 ± 477.22) No/mm2] was significantly higher than Iso injury group((2605.93±361.49)No/mm2,P<0.01).The differences of myocardial CD34,VEGF,KDR/flk-1 mRNA expression between groups were statistically significant(F=17.83,4.29,4.10,all P<0.01).Compared to Iso mjury group[CD34(23.85±6.06),VEGF(31.80±8.05),KDR/flk-1(30.16±8.01)]were higher in the GM-CSF group[CD34(44.04±10.13),VEGF(49A±11.59),and KDR/flk-1(46A9±7.90),all P<0.01].The expressions of myocardiM VEGF mRNA and its receptor KDR/flk-1 mRNA was positively correlated(r=0.725,R2=0.526,P<0.01).Conclusions GM-CSF prelreatmcnt increases the density ofnew blood vessels in myocardium,and reduces the Iso-induced myocardial injury in rats.

Objective To investigate the clinicopathological features and risk factors of lymph node metastasis of gastrointestinal neuroendocrine neoplasms (GI-NENs).Methods The retrospective case-control study was conducted.The clinicopathological data of 467 patients with GI-NENs who were admitted to the Fourth Hospital of Hebei Medical University from January 2006 to December 2015 were collected.Observation indicators:(1) occurrence sites and pathological classification of GI-NENs;(2) pathological characteristics of surgical specimens of GI-NENs;(3) univariate analysis and multivariate analysis affecting lymph node metastasis of GI-NENs:sex,age,tumor location,tumor diameter,pathological classification,pathological stage and tumor invasive depth.The univariate analysis and multivariate analysis were respectively done using the chi-square test and Logistic regression model.Results (1) Occurrence sites and pathological classification of GI-NENs:of 467 patients with GI-NENs,tumors of 304,15,7,14 and 127 patients were located at stomach,duodenum,small intestine,colon and rectum,respectively.Tumor diameter was 0.3-12.0 cm,with an average diameter of 2.2 cm.Of 467 patients with GI-NENs,G1 and G2 of neuroendocrine tumors (NETs),G3 of neumendocfine carcinomas (NECs) and mixed adenoneuroendocfine carcinomas (MANECs) were respectively detected in 209,64,146 and 48 patients.Lymph node metastasis rate of GI-NENs was 31.48％ (147/467).(2) Pathological characteristics of surgical specimens of GI-NENs:NETs were high-differentiated NENs.Ceils of NETs were solid and nest-,trabeculum-and tubular-shaped,and consisted of small or medium cells,with moderate amount or massive cytoplasms,round or oval nucleus,particle-shaped chromatin,unobvious nucleolus and positive endocrine markers.There were abundant of small blood vessels and surrounding fibrous stroma in peripheral tumor cell nests.NECs were low-differentiated NENs and included small cell carcinoma and large cell NEC.Cells of small cell carcinoma were small round or oval and looked similar to lymphocytes,with few amount cytoplasms,fine granularshaped or hyperchromatic nucleus and common mitosis figures.Cells of large cell NEC were large and greater than 3 lymphocytes,arrayed in organoid-or chrysanthemum-shape,with massive cytoplasms,coarse particle-shaped chromatin,obvious nucleus,clear mitosis figures and large laminar-shaped necrosis.There were different positive expressions of endocrine markers between small cell carcinoma and large cell NEC.MANECs had the characteristics of glandular cavity formation of traditional adenocarcinoma and NENs.Results of immunohistochemical staining in 467 patients showed that Ki-67 of 467 patients was positive;CD56 in 379 of 428 with CD56 test was positive;synaptophysin (Syn) in 416 of 422 with Syn test was positive;cytokeratin (CK) in 354 of 396 with CK test was positive;chromogranin (CgA)in 264 of 388 with CgA test was positive;neuron specific enolase (NSE) in 287 of 346 with NSE test was positive.(3) Univariate analysis and multivariate analysis affecting lymph node metastasis of GI-NENs:results of univariate analysis showed that sex,tumor location,tumor diameter,pathological classification,pathological satge and tumor invasive depth were related factors affecting lymph node metastasis of patients with GI-NENs (X2 =20.654,18.182,26.788,184.709,163.738,195.391,P＜ 0.05).Results of multivariate analysis showed that pathological classification and pathological stage were independent influenced factors affecting lymph node metastasis of patients with GI-NENs (HR =2.129,7.171,95％ confidence interval:1.273-3.561,-2.327-22.098,P＜0.05).Conclusions GI-NENs are mostly located on the stomach and rectum.Results of immunohistochenical staining could help diagnosis of GI-NENs.Pathological classification and pathological stage are independent influenced factors affecting lymph node metastasis of patients with GI-NENs.

Objective To investigate the clinical significance of body composition monitor (BCM) in evaluating the dry weight of hemodialysis patients.Methods Fifty-four hemodialysis patients who reached the dry weight according to clinical assessment were enrolled.The volume load was measured with BCM,and the pre-dialysis blood pressure,plasma B type natriuretic peptide (BNP) and echocardiogram parameters were recorded.Results BCM results showed that,in 54 hemodialysis patients,15 patients presented overhydration and 13 patients underhydration.According to the results of BCM,all of the 15 overhydration patients and some of the 13 underhydration patients adjusted their dry weight.According to the BCM results and the pre-dialysis blood pressure,the patients were divided into 4 groups:group A (without overhydration,the pre-dialysis blood pressure ＜ 150 mmHg,1 mmHg =0.133 kPa),23 cases;group B (without overhydration,pre-dialysis blood pressure ≥ 150 mmHg),16 cases;group C (overhydration,pre-dialysis blood pressure ＜ 150 mmHg),7 cases;and group D (overhydration,pre-dialysis blood pressure ≥ 150 mmHg),8 cases.There were no significant differences in pre-dialysis,plasma BNP and the echocardiographic parameters among the 4 groups (P ＞ 0.05).Conclusions BCM is a simple and convenient tool to evaluate the volume status of hemodialysis patients,It can give guidance of dry weight regulation.Compared with the other clinical assessment methods such as pedal edema,the blood pressure and plasma BNP,it is more accurate and practical.

Objective To investigate the association of serum leptin(LEP),adiponectin(ADPN)and leptin-to-adiponectin(L/A)ratio with cardio ankle vascular index(CAVI)in the patients maintaining hemodialysis(MHD).Methods Sixty MHD patients and thirty healthy volunteers were involved in the study.The levels of LEP and ADPN were determined by ELISA.Atherosclerosis was evaluated by the cardio ankle vascular index which was measured by using a VaSera VS-1000 machine.Results The levels of serum LEP and ADPN in hemodialysis patients were significantly higher than those in healthy controls([7.99 ± 1.21]μg/L vs.[4.18 ± 1.10]pg/L)and([15.12 ± 4.68]mg/L vs.[8.58 ± 2.23]mg/L),respectively,P ＜ 0.01].With the progression of atherosclerosis,the levels of serum LEP increased significantly,while the levels of serum ADPN decreased significantly.The L/A ratio was dramatically increased in patients with atherosclerosis.Multiple stepwise regression analysis showed that independent risk factors associated with CAVI include age,diabetes,levels of LEP and L/A ratio.Conclusion The increased serum LEP level and decreased serum ADPN level may be involved in the progression of atherosclerosis in MHD patients.The L/A ratio may be a powerful independentpredictor for CAVI in MHD patients.
