Objective:To explore improving impact of Sdosodine Hydrochlorida(SBHL) on immune fuction in mice treated with cyclophosphamide(CTX).Methods:BALB/c mice treated with CTX were administrated with SBHL(40 mg/kg) for 7 d.The weights of spleens and thymus of the mice,specific antibody formation of splenocytes,serum agglutinin titer and hemolysin CH50 in mice immunized with SRBC were assayed.The proliferation of mouse splenic lymphocytes actived with ConA were measured.The peritoneal macrophage phagocytosis in mice were analysized.Results:After treatment with SBHL,the indexes of thymus and spleen,and the proliferation of mouse splenic lymphocytes activated with ConA were increased markedly in a dose-dependent manner.The peritoneal macrophage phagocytosis was also improved.Only at the dose of 40 mg/kg were the weights of spleens of mice,specific antibody formation by splenocytes,serum agglutinin titer,hemolysin CH50 of the mice immunized with SRBC increased significantly.Conclusion:SBHL has a remarkable improving effect on the immune functions inhibited by CTX in mice,which may be another important antitumor mechanism of SBHL.

Protective effects of acupuncture on myocardial ischemia in each stage have been confirmed increasingly, while there was no in-depth research in terms of histone modifications. Histone modification is an important part of epigenetics. It is also the focus of molecular biology and basic medical research. In this paper, the relationship of histone modifications and gene expression of heart was first explained. Then, the recent research progress of modified histones, which was the direct alteration of gene expression induced by histone modifications on the degree and prognosis of myocardial ischemic injury, was reviewed. This investigation introduced epigenetic regulation in the protection mechanism of myocardial ischemia by acupuncture. It provided new ideas and directions for the study of molecular mechanism of acupuncture efficacy.

Objective To analyze the genetic polymorphism of three short tandem repeat (STR) double loci,namely,six STR loci in the Chinese population of Han nationality in Jilin district and to obtain the corresponding genetic data.Methods DNA was extracted from the blood cells of one hundred and three unrelated individuals of Han nationality in Jilin district;Six loci were divided into three groups which were groupⅠ(TPOX+CSF1PO),groupⅡ(D3S1358+D13S317) and groupⅢ(D5S818+D19S400).The extracted DNA were amplified with PCR multiplexing method.The PCR products were analyzed by non-reduced PAGE,followed by silver staining.The allele frequency distributions of six STR loci were studied by statistical procedures.The heterozygosity (H),discrimination power (DP),probability of exclusion (PE) and polymorphic information content (PIC) were calculated.Results The allele frequencies of six loci were obtained.The genotypes distributions of the loci were consistent with Hardy-Weinberg equilibrium and had higher heterozygosities and PIC.The H,DP,PE and PIC were 0.7511-0.8376,0.8273-0.9247,0.5167-0.6718 and 0.7100-0.8195 respectively.Conclusions The three STR double loci exhibited higher polymorphism and were better genetic markers.The data on the allele frequencies of these six STR loci may be used in individual identification,paternity testing and in other population genetic researches.

Objective: To analyze the expression of CMTM1-v17 in normal prostate tissue and prostate carcinoma originated cell lines, and study its impact on the transactivation of androgen receptor and the possible mechanism. Methods: The expression of CMTM1-v17 in normal prostate tissue was analyzed with immunohistochemistry method. In immounocytochemistry was used to analyze the expression of CMTM1-v17 in prostate carcinoma originated cell lines. Luciferase assay was used to study the impact of CMTM1-v17 on the transactivation of AR and its mechanism. Results: The results of immunohistochemistry showed that CMTM1-v17 was highly expressed in prostate. In prostate cancer originated cell lines, CMTM1-v17 could also be detected in prostate cancer originated cell lines PC3, Du145 and LNCaP. And the results of luciferase implied that the relative luciferase activity of the PC3 cells transfected with 1 ?g and 2 ?g pCDI-CMTM1-v17 plasmids separately were 70.8 and 34.7, compared with the control set as 100. When trichostatin A, the inhibitor for histone deacetylase, was used, the repression of androgen receptor could be recovered with trichostatin A treatment,for the relative luciferase activity of the PC3 cells transfected with 1 ?g and 2 ?g pCDI-CMTM1-v17 plasmids and treated with 100 nmol/L trichostatin A rebound to 90.9 and 86.4. Conclusion: CMTM1-v17 is highly expressed in both normal prostate and prostate carcinoma originated cell lines. It may recruit histone deacetylas to inhibit the function of androgen receptor.

OBJECTIVETo observe the clinical efficacy on chronic stable angina pectoris treated with acupuncture at Neiguan (PC 6) and explore the impacts of acupuncture on peripheral blood neutrophil to lymphocyte ratio (NLR) in the patients of stable angina pectoris.

METHODSThirty patients of chronic stable angina pectoris met the inclusive criteria were randomized into an acupuncture group (15 cases) and a medication group (15 cases), and a healthy control group (15 cases of the same ages) was set up separately. In the acupuncture group, at the same time of the basic medication, acupuncture was applied to bilateral Neiguan (PC 6), once every two days, 3 days a week, totally for 4 weeks. In the medication group, the basic medication was applied, without acupuncture intervention. In the healthy control group, no any intervention was applied. The attack frequency of angina pectoris, dose of nitrogly-cerin, the evaluation of visual analogue scale (VAS), Seattle angina questionnaire (SAQ), the six-minute walking test (6MWT), the self-rating anxiety scale (SAS) and the self-rating depression scale (SDS) were observed before and after treatment in the subjects. Additionally, the peripheral blood cells were detected to analyze specifically the changes in NLR before and after treatment and observe the relationship between NLR and clinical efficacy.

RESULTSCompared with the medication group, the attack frequency of angina pectoris was reduced within 30 days (P<0.01); the dose of nitroglycerin was reduced (P<0.01); VAS was reduced (P<0.01) and SAQ was increased (P<0.05) in the acupuncture group. The differences in 6 MWT, SAS and SDS were not significant between the two groups after treatment (all P>0.05). Additionally, compared with the medication group, in 30 days of acupuncture, NLR was reduced apparently in the acupuncture group (P<0.05).

CONCLUSIONAcupuncture relieves the clinical symptoms of chronic stable angina pectoris, but has not apparent effects on motor ability and psychological health. Corresponding to that before treatment, the decreased NRL in the patients of acupuncture group suggests the potential good prognosis on coronary heart disease after acupuncture.

PURPOSE: Nursing students experience a high degree of perceived stress during skills training. The resulting academic sentiment is worthy of research. This study examined the learning motivation as a mediator in the association between perceived stress and positive deactivating academic emotions in nursing students undergoing skills training. METHODS: A survey was conducted on 386 third-year undergraduate nursing students at a university in Changchun, China, in 2017. The survey included the items on perceived stress, learning motivation during nursing skill training, and general academic emotion. There were 381 valid responses (response rate=98.7%). Based on the results of partial correlation and stepwise multiple regression equations, the study examined the mediation model between perceived stress, learning motivation and positive-deactivating academic emotions using process 2.16 (a plug-in specifically used to test mediation or moderation effect in SPSS). RESULTS: There was a significant negative correlation between students' perceived stress and learning motivation during nursing skills training and positive-deactivating academic emotions. Nervousness, loss of control, and interest in developing reputation had significant predictive effects on positive-deactivating academic emotions. The mediating model was well supported. CONCLUSION: Learning motivation during nursing skills training lessened the damage of perceived stress on positive-deactivating academic emotions. Improving students' motivation to learn could reduce their perceived stress and build more positive emotions. Positive emotions during learning played an important role in helping nursing students improve skills and enhance their nursing competence.
