Journal of Chinese Physician 2016;18(8):1264-1268
Activating transcription factor 3 (ATF3) is a protein produced by the cells in the ischemic reperfusion injury,neuronal or liver damage,skin damage,viral oncogene expression or DNA damage.Recent studies have found that ATF3 plays an important role in the occurrence and development of human malignant tumors.

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.

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.

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 .

AIM: To evaluate the protective effects of mycophenolate mofetil on the kidneys of type 2 diabetic rats and discover their mechanisms. METHODS: Wistar rats were divided into three groups, such as normal control rats, diabetic rats, and diabetic rats in the treatment with mycophenolate mofetil (MMF, 15 mg?kg -1 ?d -1 ). Thirteen weeks later, urinary albumin excretory rate (UAE), creatine clearance (Ccr), blood glucose, blood insulin and blood lipid were measured, and kidney pathology was observed. Inmmunohistochemistry was used to analyze the expression of CTGF, ColI and ColⅢ. RESULTS: Mycophenolate mofetil decreased UAE, Ccr and reduced glomerular volume. The expression of CTGF and deposition of ECM decreased after diabetic rats received mycophenolate mofetil. CONCLUSION: Mycophenolate mofetil can protect the kidney of diabetic rats. Its mechanism may be related to the decrease of CTGF expression and extracellular matrix deposition in renal tissue.

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.
