Objective:To explore the effect of Brain HQ visual training on memory function in lymphoma patients with chemotherapy-related cognitive impairment.Methods:From January to December 2019, 39 hospitalized patients in lymphoma department were selected as the research object, and divided into intervention group (19 cases) and control group (20 cases) by the order of admission. The control group was given routine nursing, and the intervention group was given Brain HQ visual training. The two groups of patients used the auditory learning test to evaluate the memory function effect at the time of enrollment, after 2 cycles and 4 cycles.Results:After 2 cycles intervention, there were no statistically significant indicators for immediate recall, short-term delayed recall, long-term delayed recall, re-recognition, and correct recall ( t values were 0.575-1.248, P> 0.05); After 4 cycles of chemotherapy, the three indicators of long-term delayed recall, recognition and correct recall of the intervention group were (6.00±1.59), (9.05±1.81), (36.00±4.27) points, while (4.75±1.55), (8.05±1.73), (32.85±3.59) points of the control group, there was a statistically significant difference in ( t values were 3.384, 2.373, 3.010, P < 0.05); repeated measures analysis of variance showed The total indicators of immediate recall, short-term delayed recall, long-term delayed recall, recognition and correct recall were not statistically significant in both groups ( F values were 0.329-1.462, P>0.05). Conclusion:The effect of Brain HQ visual training on memory function are not clear, but with the change of intervention time, memory indicators are constantly improving, Brain HQ visual training has certain practicability.

The importance of individual therapy based on pharmacogenomics has been emphasized in cancer therapy. To explore the individual therapy of colorectal cancer, the progress of molecular markers which influence the efficacy of anti-tumor drugs containing fluorouracil, oxaliplatin, CPT-11, monoclonal antibody drugs is reviewed in this article.

Objective To detect the expression of Id1 and p53 in human breast cancer and study their relationship. Methods To choose 80 cases of breast cancer from the surgical department of Tangshan people's hospital. All patients didn't get radiotherapy and chemotherapy before surgery. The expression of Idl and p53 of breast cancer were studied by using SABC immunohistochemistry. Results The expressions of Id1 were found in cytoplasm, while the expression of p53 was found in cell nucleus. The positive rates of Id1 and p53 were 87.5 %(70/80)and 90.0%(72/80) respectively in breast cancer tissues. The expression of Id1 and p53 were significantly higher in breast cancer tissue than those in adjacent non-tumor breast tissues,benign tumor tissues and normal breast tissues(P ＜0.05). The positive rates and expression intensity of Id1 in breast cancer had significant correlation with lymph node metastasis and pTNM stage of the tumor, but had no significant correlation with age, histological differentiation and tumor size. The positive rates and expression intensity of p53 in breast cancer had significant correlation with lymph node metastasis of the tumor, but had no significant correlation with age, histological differentiation,tumor size and pTNM stage. Conclusion Expression of Id1 in human breast cancer is up-regulated. Its expression is associated with lymph node metastasis and TNM stage and represents an independent marker for prognosis of breast cancer. To reduce the expression of Id1 will become the strategy of curing breast cancer. Expression of Id1 and p53 in human breast cancer have the same clinic significance. Each of them can represent an independent marker for prognosis of breast cancer.

Orthostatic hypertension (OHT)in children was first proposed by Chinese scholars in 2012.The diagnostic criterion was revised in 2015.OHT in children was not rare in clinical practice.Children and adolescents are susceptible to OHT when they suddenly change posture or standing for a long time.The mechanisms of OHT were not clear.Dizziness,headache,nausea and vomiting were the main manifestations of OHT.Severe symptom in childhood OHT includes syncope.The prognosis of OHT was good,but the abnormal blood pressure will last to adults.Further study in OHT will help to predict the risk of cardiovascular and cerebrovascular diseases and help to evaluate target or-gan injury.The treatment of OHT has been explored,and non -medical treatment is the main option.Study in medical treatment for OHT has not been conducted.Now,the diagnostic criteria in children,epidemiologic status,clinical fea-tures and treatment of OHT were focused to deepen the understanding of OHT in children and improve the clinical standard of the disease.

Objective To understand the current situation of iodine deficiency disorders (IDD),iodine nutritional status and implementation situation of the prevention and control measures before and after the adjustment of edible salt iodine level in Xi'an City,and to provide a basis for scientific prevention and control of IDD.Methods In 2011,seven counties (areas) of Xi'an City were selected,including Lintong,Weiyang,Chang'an,Lantian,Gaoling,Zhouzhi and Huxian,and five subareas were selected according to the five directions as east,west,south,north and centre in each county (area),one township was selected in the centre subarea and two townships were selected in other subareas,four villages were selected in every township,edible salt samples of eight households were selected in every village to detect salt iodine.Six areas of Xi'an City were selected,including Yanta,Beilin,Yanliang,Lianhu,Xincheng and Baqiao,one township was selected according to the five directions as east,west,south,north and centre in each county,four villages were selected in every township,edible salt samples of 15 households were selected in every village to detect salt iodine.One school was respectively selected according to the five directions as east,west,south,north and centre in 13 counties,42 children aged 8-10 were selected in every school to detect goiter.Two schools were selected in Beilin,Lianhu and Xincheng,respectively,30 children aged 8-10 were selected in every school to detect urine iodine.The remaining 10 counties were respectively divided according to the five directions as east,west,south,north and centre,two schools were selected in the centre subarea,30 children aged 8-10 were selected in every school to test urine iodine,one school was selected in other subareas,15 children aged 8-10 were selected in every school to detect urine iodine.In 2015,13 counties were selected,one township was selected according to the five directions as east,west,south,north and centre in each county,four villages were selected in every township,and edible salt samples of 15 households were selected in every village to detect salt iodine.One school was selected in every township,42 children aged 8-10 were selected in every school to detect goiter.Meanwhile,40 children aged 8-10 were selected in every school to detect urine iodine.Results The median of salt iodine was 33.70 mg/kg in 2011,which was higher than that in 2015 (24.96 mg/kg),the difference was statistically significant (Z =31.059,P ＜ 0.05).In 2012 and 2015,the coverage rates of iodized salt were 99.79％ (3 808/3 816) and 99.90％ (3 896/3 900),consumption rates of qualified iodized salt were 99.32％ (3 791/3 816) and 97.64％ (3 808/3 900).The rate of weighted goiter in 2011 was 2.76％,which was higher than that in 2015 (1.17％),the difference was statistically significant (X2 =15.11,P ＜ 0.01).The median of urinary iodine was 292.5 μg/L in 2011,which was higher than that in 2015 (259.0 μg/L),the difference was statistically significant (Z =2.862,P ＜ 0.05).Conclusion The population iodine nutritional status is more than sufficient in Xi'an City after adjustment of edible salt iodine level,there is still a space for lowering the iodine level in edible salt.

To test whether Con A has antirejection effect on mouse islet allograft, 600-700 handpicked islets of C57BL/6 mice was transplanted beneath the kidney capsule of the streptozotocin induced diabetic BALB/C recipients. In control group the mean survival time (MST) of the grafts was 14.1?2.4 days. Treatment with Con A significantly prolong the MST of the islet allografts. In group with Con A treatment of the donor islets prior to the transplantation the MST was 25?5.4 days. The MST increased sigificantly after ip injection of Con A to recipient mice. The combined treatment of islet and recipient with Con A resulted in a prolongation of MST to 25.2?4.4 days. The experiments concerning the mechanisms of the antirejection effect of Con A showed that Con A was able to combine with the islet cell membrane well masking perhaps the histocmpatibility antigen. Furthermore the lymphocytes of mice after i. p Con A injection suppressed the lymphocyte proliferation reaction of the svnergic mice to mitogen.
