BACKGROUND:To in vitro isolate neural stem cel s with high purity and uniform biological properties and to establish a complete set of neural stem cel culture system is the basis for neural stem cel research.
OBJECTIVE:To establish an isolation and culture system for neural stem cel s from newborn mouse hippocampus, olfactory bulb and cortex and to analyze the biological properties of cel s.
METHODS:Neural stem cel s were isolated from the hippocampus, olfactory bulb and cortex tissue of newborn Kunming mice by mechanical separation and trypsin digestion. Serum-free culture technology, mechanical pipetting and trypsin digestion were used for subculture of neural stem cel s. 10%fetal bovine serum was used to induce differentiation of neural stem cel s. Neural stem cel s and their differentiated products were identified by
immunofluorescent staining of Nestin, CD133,β-TubulinIII, glial fibril ary acidic protein.
RESULTS AND CONCLUSION:The neural stem cel obtained from newborn mouse hippocampus, olfactory bulb and cortex had the capacity of self-renewal and differentiation which were positive for Nestin and CD133. After induction with fetal bovine serum, neural stem cel could differentiation toβ-tubulinIII or glial fibril ary acidic protein positive cel s that were neurons and astrocytes. This experiment has successful y established the neural stem cel isolation, culture, identification and induction system, providing experimental basis for subsequent studies of neural stem cel s.

Objective To detect the expression levels of serum ITAC, Fractalkine, IL-8, IL-17A, IL-7 and TNF-α in patients with gastric cancer, and to explore correlation among them, as well as their association with different clinical characteristics.Methods The levels of the 6 kinds of cytokines in serum of 46 gastric cancer patients (gastric cancer group) and 30 healthy people (healthy control group) were detected.Results Compared with those in healthy control group, the levels of serum ITAC, Fractalkine, IL-8, IL-17A, IL-7 and TNF-α in gastric cancer group were significantly increased [22.26 (32.83) pg/ml vs 11.95 (9.99) pg/ml, P =0.001;62.21 (82.23) pg/ml vs 26.47 (50.87) pg/ml, P =0.050;4.50 (10.38) pg/ml vs 2.06 (3.17) pg/ml, P =0.002;0.83 (2.01) pg/ml vs 0.21 (0.85) pg/ml, P=0.013;3.46 (1.90) pg/ml vs 2.11 (1.48) pg/ml, P=0.001;1.21 (1.13) pg/ml vs 0.79 (0.37) pg/ml, P ＜ 0.001].There were correlations between cytokines (all P ＜ 0.05).The level of serum cytokines was no significant difference between gastric cancer patients with lymph node metastasis and those without lymph node metastasis (P ＞ 0.05).Conclusions The high level of serum ITAC, Fractalkine, IL-8, IL-17A, IL-7 or TNF-α may be related to the occurrence and development of gastric cancer.High level of serum IL-8 may be a marker of poor prognosis of gastric cancer, and interaction between the various cytokines also has a certain association with tumorigenesis.

Objective To study the relationship of interleukin-18 (IL-18)gene-137G/C polymorphisms in the promoter region with cerebral infarction(CI) and the effect of integrin gene polymorphisms on plasma lipid and lipoprotein levels. Methods Polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) were used for the detection of integrin genotypes in 190 patients with CI and 210 healthy controls. The plasma lipid and lipoprotein levels were measured by routine method. Results The distributions of IL-18 gene -137G/C polymorphism was significantly different between CI group and control group(P ＜0. 05＝ ,The relative risk suffered from CI of C allele was 1.624 times of the G allele (OR = 1.624,95% CI: 1.134 ～ 2.324), The level of plasma lipid C allele carriers was significantly higher than no carriers(P ＜0.05＝. Conclusion IL-18 gene-137G/C polymorphism was associated with CI, C allele may be genetic susceptibility gene for CI.

Objective:To summarize the best evidence for anxiety and depression management in adults with coronary heart disease (CHD).Methods:Evidence regarding anxiety and depression management of adults with CHD was retrieved from the British Medical Journal best practice, UpToDate, Guidelines International Network, National Institute for Health and Care Excellence, Scottish Intercollegiate Guideline Network, Registered Nurses Association of Ontario, Cochrane Library, the Joanna Briggs Institute (JBI), PubMed, Embase, Medline, Web of Science, China National Knowledge Infrastructure, and WanFang Data. These publications included guidelines, systematic reviews, expert consensus, and evidence summaries. The data retrieval time was from the establishment of the databases to September 13, 2021. The search terms included coronary heart disease, psychology, anxiety and depression, and the data was sorted on September 14-23, 2021. Two researchers evaluated the quality of the literature and extracted data independently according to both AGREE Ⅱ and the evaluation tools of the JBI evidence-based healthcare center. The evidence level was graded by using the evidence preliminary classification system and the evidence recommendation level system of the JBI evidence-based healthcare center. The recommended strength of the evidence was determined with the guidance of JBI′s evidence structure and the discussion within the research group and expert opinions, and then the best evidence for anxiety and depression management in adults with CHD were extracted, summarized and analyzed. Results:A total of 22 articleswere included, including 5 clinical guidelines, 14 systematic reviews, 2 expert consensuses and 1 evidence summary. Three articles of the guidelines were graded B with the up-mentioned recommendtation standard, and the other two were graded A. In the systematic reviews, five articles were rated as grade B, the other nine articles as grade A, and 95% of the items were evaluated as “yes”. The evaluation results of all items in the expert consensuses were “yes”, and the quality grade was A. The evidence summary involved 32 pieces of best evidence regarding five aspects (mental health management mode, risk factor assessment and prevention, psychological problem identification and screening, psychological adjustment and intervention, drug treatment), of which 60% were class 1 evidence, and 34% were recommended with strength A.Conclusions:The overall quality of the literature and the level of evidence regarding anxiety and depression management in adults with CHD are high. The key to anxiety and depression management in these patients is innovating the mode of mental health management and implementing effective risk factor assessment and prevention, psychological problem identification and screening, psychological adjustment and intervention, and drug treatment.
