Objective To observe the effect of atropine mydriasis, wearing myopia glasses for short or long distance, and massage on preventing and controlling myopia in teenagers and children. Methods A total of 198 myopia cases (involving 393 eyes) were randomized into control group and treatment group. The control group was given eyesight examination after mydriasis with atropine sulfate eye gel and wearing myopia glasses for long distance. The treatment group was given eyesight examination after mydriasis with atropine sulfate eye gel, wearing myopia glasses for short distance, and massage therapy. Eyesight examination was carried out once every 2 months and lasted for one continuous year. The changes of diopter were compared between the two groups. Results ( 1) Of 194 affected eyes from the treatment group, 96 eyes were effective, 68 were stabilized, and the effective rate was 45.5%and stabilizing rate was 35.1%. Of 199 affected eyes from the control group, 3 eyes were effective, 9 were stabilized, and the effective rate was 1.5%and stabilizing rate was 4.5%. The differences of effective and stabilizing rates were significant between the two groups ( P<0.01). ( 2) After treatment, the myopia diopter was increased in the control group ( P<0.01 compared with that before treatment) , and the myopia diopter in the treatment group maintained stable ( P>0.05). The difference of diopter was significant between the two groups (P<0.01). (3) The difference of astigmatism was insignificant in both groups before and after treatment and between the two groups after treatment (P>0.05). Conclusion Mydriasis with atropine sulfate eye gel, wearing myopia glasses for short or long distance, and focal massage therapy show certain preventive effect on myopia in teenagers and children by controlling the development of myopia diopter.

Objective To explore the relationship among emotional resilience,stress and school adjustment.Methods Adolescent life events check-list,adolescent emotional resilience scale and school adjustment scale of middle school students were conducted among 394 junior high school students.Results (1)The emotional resilience score and emotion recovery score of male junior high school students(46.07±8.56,24.43±5.80) were higher than that of female ones(44.39±8.39,23.27±5.37),and the differences were statistically significant(t=1.97,2.05,P＜0.05).The total score of emotional resilience(45.46±8.50,44.83±8.56) was not statistically related with whether they were the only children(t=0.68,P=0.50).The emotional resilience score and positive emotion score of rural junior high school students(44.04±8.53,20.63±5.35)were lower than that of urban ones (46.46± 8.34,22.15 ±4.72),and the differences were statistically significant(t=-2.86,-2.99,P＜0.01).The total score of emotional resilience (47.23±7.82,44.63±8.45,43.00±8.97) in different grades was statistically significant (F=8.86,P=0.00),and the first grade students were higher than the second and third year students.(2)Psychological stress was negatively related with emotional resilience and school adjustment(r=-0.23～-0.35,P＜0.01),and emotional resilience was positively correlated with school adjustment(r=0.12 ～ 0.29,P＜0.01).The relationship between stress and school adjustment were mediated by positive emotion and emotional recovery (the mediating effect were 11.11％,21.15％).Conclusion Frotional resilience plays a mediating role between psychological stress and school adjustment.

AIM: To explore the protein levels of chemokine receptor 7 (CCR7) and vascular endothelial growth factor ( VEGF)-C in breast carcinoma , and to investigate the effects of CCR 7 and VEGF-C on prognosis of breast carcinoma.METHODS:The protein expression levels of CCR 7 and VEGF-C in the breast carcinoma tissues and normal breast tissues were detected by the method of immunohistochemistry .At the same time, the relationship between clinico-pathologic characteristics and the protein expression of CCR 7 and VEGF-C in the breast carcinoma tissues was analyzed . The relationship between the protein expression of CCR 7 and VEGF-C and survival time of the breast cancer patients was estimated by Kaplan-Meier method.RESULTS:The positive expression rates of CCR 7 and VEGF-C in the breast carcino-ma tissues were significantly higher than those in the normal breast tissues (P<0.01).A positive correlation was observed between the protein expression of CCR7 and the protein expression of VEGF-C in the breast carcinoma tissues (r=0.613, P<0.01).The protein expression of CCR7 and VEGF-C was correlated with lymph node metastasis and TNM stage (P<0.05), but both were not related to patients ’ age, primary tumor size, estrogen receptor and progesterone receptor .The survival time of the patients with CCR 7 and VEGF-C positive expression was significantly shorter than that of the patients without the expression (P<0.05).CONCLUSION:The positive expression of CCR7 and VEGF-C proteins is associated with the prognosis of breast cancer , and combined detection of CCR 7 and VEGF-C protein expression levels may be helpful to judge the prognosis of breast cancer .

0. 20) after D test of normality. The normal range of GEMP was 63. 11-72. 94 ?mol fructose/L (P= 95%). When clinical cardiovasculopathy, nephropathy, retinopathy,peripheral neuropathy and auditus reduction in the aged were compared between two groups of diabetic patients, one with normal and another with abnormal values of GEMP, the clinical indices, excepting cardiovasculopathy, were significantly different between the groups.

Over-expression of APP and Swedish mutation could cause some familial early onset AD. In this study, a primary screening was conducted of effective small interference RNAs (siRNAs) targeted wild type APP (APPwt) and Swedish mutant APP (APPswe). One siRNA targeting APPwt and the other siRNA targeting APPswe were designed. All these siRNAs were endogenously expressed by siRNAs expressing plasmids. COS-7 cells were transiently co-transfected with APP-GFP recombinant plasmids and siRNA expression vector. The silencing effect of each siRNA was quantitatively assessed by the level of expression of green fluorescent protein (GFP). It was found that the siRNAs silenced APPwt and APPswe to different degrees. siRNA directed against APPswe was more effective in suppressing the expression of fusion gene of APPswe than that of APPwt. The silencing effect of siRNA directed against APPswe indicating allele-specific silencing property of the siRNAs. Therefore, siRNAs directed against APP play an important role both in the therapeutic study of Alzheimer disease and functional exploration ofAPP gene.

Objective To explore the effect of suledexide on renal injury and podocalyxin expression of podocytes in STZ diabetic desoxycorticosterone acetate (DOCA)-hypertensive rats. Methods Wistar rats were subjected to subcutaneous injection of streptozotocin(STZ), followed by uninephrectomy and subcutaneous administration of DOCA. Diabetic and hypertensive rats were randomly allocated to treatment with sulodexide or a combination of sulodexide and telmisartan for 8 weeks. Blood pressure (BP), 24-hour urinary albumin were measured every 2 weeks. Blood and urinary samples were collected to detect biochemical indexes of plasma and urinary β-acetyl-β-D-glucosaminidase (NAG) at the end of the study. Immunohistochemistry (IHC), RT-PCR and Western blot were performed to examine the expression and distribution of podocalyxin. Results STZ +DOCA-treated rats progressively developed hypertension, albuminuria and hyperglycemia. Hyperlipidemia and hypoinsulinemia were found in diabetic and hypertensive rats compared with controls. Albuminuia was significantly reduced in sulodexide group at week 8 and sulodexide plus telmisartan group at week 6 and week 8. Blood pressure decreased in sulodexide plus telmisartan group. No significant effects on lipid and glucose metabolism were observed in all treated groups. Histopathological index increased in STZ+DOCA-treated rats, but was significantly lower in sulodexide group as well as sulodexide plus telmisartan group. The number of podocytes on glomerular cross-section of the four groups were comparable. Segmental loss and down-regulation of podocalyxin were detected in STZ+DOCA-treated rats, which were greatly attenuated by sulodexinde, meanwhile, combination treatment preserved more podocalyxin expression in glomeruli than sulodexide monotherapy. Conclusion Sulodexide effectively reduces albuminuria, prevents loss of podocyte podocalyxin and alleviates renal damage in STZ diabetic DOCA-hypertensive rats.

Objectiye To explore the expression of COX-2 and VEGF and its clinical significance in non-Hodgkin lymphoma (NHL). Methods The expression of COX-2 and VEGF were detected by immunohistochemistry in 42 cases of NHL and 20 cases of lymph node with benign pathological change. Results The positive rate of COX-2 and VEGF was 45.24% and 73.81% in NHL respectively. The expression rate of VEGF was positively correlated with that of COX-2 in tissues of NHL ( x2 = 4. 63, P ＜ 0. 05).The expression of COX-2 was related to clinical stage and histopathologic grade of NHL ( x2 = 5.43, P ＜0. 05), but it had no association with gender, age, B symptoms, and IPI. The expression of VEGF was significantly related with aggression, B symptoms and IPI ( x2 =8. 979, 8. 893,6. 434, P ＜0. 05), but it had no association with age, gender and clinical stages. Conclusion COX-2 and VEGF may be involved in NHL tumorgenesis, and COX-2 may accelerate angiogenesis by increasing VEGF expression. Specific COX-2 inhibitors may be a novel therapeutic approach for NHL.

As an important branch of systematic biology, metabonomics is an emerging discipline following genomics, proteomics and transcriptomics. It focuses on the quality and quantity changes of the small molecular metabolites in appointed physiological or pathological state, and provides important informa?tion for studies of diseases mechanism, clinical early diagnosis and prognosis prediction. Compared with tra?ditional clinical diagnostic method ( single index) , metabonomics method can more comprehensively analyze metabolites changes in the body. This review introduces the metabonomics and summarizes its application in thyroid diseases.

Objective To investigate the efficacy observation of transcranial direct current stimulation (tDCS)for improving the attention in patients with infarction in basal ganglia area. Methods Sixty consecutive patients with basal ganglia infarction admitted to the Department of Rehabilitation Medicine,the First Affiliated Hospital of Nanchang University from May 2015 to May 2016 were enrolled. They were randomly divided into either a control group or a test group according to the random number table (n = 30 in each group). The patients in both groups received routine rehabilitation training,and those in the test group received tDCS therapy synchronously,and the control group received the sham tDCS stimulation. The evaluations and analyses were conducted with the Montreal cognitive assessment (MoCA),d2 test of attention,and event-related potential-P300 (ERP-P300),respectively in all patients before intervention and 4 weeks after intervention,and they were compared between the groups. Results There was no significant difference before intervention between the two groups (all P > 0. 05). Compared with before intervention,the ERP-P300 latencies were reduced,the amplitudes were increased after intervention in the patients of the test group and the control group (all P < 0. 05). The MoCA total scores (the test group:22. 7 ± 2. 7 vs. 15. 5 ±
2. 4;the control group:17. 2 ±2. 5 vs. 15. 6 ±2. 3),attention dimension scores (the test group:4. 6 ± 1. 2 vs. 2. 4 ± 1. 6;the control group:3. 6 ± 1. 5 vs. 2. 5 ± 1. 5),and the total completion of d2 attention test task, total scores,and concentration degree scores (the test group:295 ± 31 vs. 250 ± 45,279 ± 38 vs. 223 ± 52, 97 ± 22 vs. 75 ± 25;the control group:276 ± 33 vs. 247 ± 45,257 ± 39 vs. 211 ± 56,84 ± 23 vs. 71 ± 24) were all increased (all P < 0. 05),and all the indexes of the test group were better than those of the control group (all P < 0. 05). Conclusion tDCS contributes to the improvement of the attention in patients with infarction in the internal capsule-basal ganglia region.
