Objective To investigate the effect of cognitive behavioral multi-level intervention on post-stroke depression. Methods 160 patients with post-stroke depression in our hospital from February 2013 to February 2015 were divided into control group (n=80) and obser-vation group (n=80). Both groups received conventional medical treatment and nursing care. The observation group received cognitive be-havioral multi-level intervention nursing care, including personal psychology, behaviour and joint relationship. Self-rating Depression Scale (SDS) was assessed, and the serum level of interleukin (IL)-1β, IL-6 and tumor necrosis factor-α(TNF-α) were mesured before and after treatment. Results After treatment, the score of SDS was lower (t=2.705, P<0.05), and the levels of IL-1β(t=8.182), IL-6 (t=2.883), TNF-α(t=2.604) were lower in the observation group than in the control group (P<0.05). The incidence of depression was also lower in the observa-tion group than in the control group ( χ 2=6.144, P<0.05) after 6 months follow-up. Conclusion Cognitive behavioral multi-level interven-tion could effectively prevent post-stroke depression.

miR-205 is differentially expressed in tumor tissues and is closely related to tumorigenesis and tumor metastasis.miR-205 can regulate the biological behaviors of tumor cells such as cell proliferation,differentiation,in situ invasion and distant metastasis by post-transcriptional regulation through binding to targeted genes.Additionally,further research of miR-205 may be helpful for tumor diagnosis,targeted therapy and prognosis.

Objective To explore the application effect of cognitive behavioral intervention on chronic obstructive pulmonary disease nursing care.Methods 80 patients with chronic obstructive pulmonary disease were randomly divided into an experimental group and a control group(n=40).Both groups were given medical treatment and conventional nursing care,and the control group was given the cognitive behavioral intervention nursing care additionally.The average days of stay,the ratio of readmission,the treatment adherence,and smoking cessation rate in one year were recorded.Moreover,the life quality of the two groups was analyzed with a CAT assessment test.Results Compared with the control group,the experimental group achieved shorter average days of stay,higher medication adherence and smoking cessation rate,lower readmission rate and admission rate.The experimental group achieved better life quality with lower CAT value than the control group.Conclusion Cognitive behavioral intervention can obviously improve the treatment effectiveness of patients with chronic obstructive pulmonarv disease.

Objective To study preoperatively on TNM staging of esophageal carcinoma by endo-scopes ultrasonography ( EUS). Methods Sixty-one patients with esophageal carcinoma were preoperatively staged by EUS. The results were compared with the postoperative histopathological staging according to the new (1997) TNM classification. Results Clinical staging of T subsets by EUS was reliable with an overall accuracy rate of 86. 9% , while that of N subsets was relatively more difficult with an overall accuracy rate of 52. 5% ; sensitivity and specificity of regional lymph nodal metastases were 88. 9% and 23. 5% respectively. Conclusion EUS is relatively an accurate measure in assessing the depth of tumor infiltration, whereas further efforts are needed to improve the accuracy in N staging. EUS will be helpful in choice of the appropriate therapeutic procedure and predicting the possibility of surgical resection.

Objective To observe the effects of differentially expressed peroxisome proliferatoractivated receptor γ (PPAR γ) on cell migration,invasion and proliferation of endometrial cancer cells.Methods Two endometrial cancer cell lines ECC-1 (ER positive) and KLE (ER negative) cells were used in this study.To up or down regulate PPARγ expression,the transient transfection by using PPARγ expression vector (PPARγ expression vector group) and PPARγ small interference RNA (PPARγ siRNA group) were done.The negative control groups were cells transfected by nonsence sequence siRNA (siRNA non sence sequence group) or empty vector (empty vector group).At the same time,cells only added with liposome were used as blank control group.Then,quantitative real time (RT)-PCR and western blot were used to detect PPARγexpression both in mRNA and protein levels.To assess the expression levels of Wnt signaling pathway,western blot was performed to analysis protein levels of β-catenin and C-myc.The effects on cell migration,invasion and proliferation using in vitro transwell migration,invasion assays and cell counting kit-8 (CCK-8) assay were further be examined.Results After transfection for 48 hours,quantitative RT-PCR and western blot showed that PPARγmRNA (5.18 ± 0.99,4.54 ± 0.89) and protein (1.45 ± 0.12,1.30 ± 0.13) expression levels significantly increased and the protein levels of β-catenin (0.44 ± 0.06,0.46 ± 0.04) and C-myc (0.42 ± 0.08,0.30 ± 0.11) decreased in PPAR γ expression vector group,while in PPARγ siRNA group,PPARγ mRNA (0.48 ± 0.08,0.53 ± 0.11) and protein (0.41 ±0.04,0.49 ±0.05) expression levels decreased and the protein levels of 3-catenin (1.18 ±0.12,0.89 ±0.07) and C-myc(0.91 ±0.08,0.77 ±0.12) increased significantly compared with control groups (all P ＜ 0.05).In vitro migration and invasion assay indicated that the migratory and invasive cell numbers of PPARγ expression vector group (ECC-1:129 ± 9,63 ± 12 ; KLE:119 ± 9,68 ± 16) were significantly decreased,while the migratory and invasive cell numbers of were PPARγ siRNA group (ECC-1:201 ± 14,142 ±9 ; KLE:170 ± 11,138 ± 7) increased significantly compared with those in control groups(all P ＜ 0.05).CCK-8 assay showed that A values (0.66 ±0.14,0.78 ±0.06) in PPARγexpression vector group were lower than those in control groups,and in PPARγ siRNA group,A values (1.42 ± 0.16,1.23 ± 0.04) were higher than those in control groups,and there were statistically significant difference among them (all P ＜ 0.05).Conclusion Up-regulated PPARγ gene expression could inhibit endometrial cancer cell migration,invasion and proliferation abilities,and down-regulated PPARγ gene expression could promote endometrial cancer cell migration,invasion and proliferation abilities.

Objective: To study the effect of genistein(Gen) on expression of monocyte chemotactic protein-1 ( MCP-1) mRNA and MCP-1 induced by oxidized low density lipoprotein (ox-LDL) in human umbilical venous smooth mulscle cells (hUVSMC). Methods: Gen at different doses (1.0?10-5、3.0?10-5、9.0?10-5mol/L) were used to observe the effect on expression of MCP-1 mRNA and MCP-1 induced by ox-LDL in hUVSMC cultures and compared with the effect of 17b-estradiol(17b-E). RT-PCR and ELISA were used to measure expression of MCP-1 mRNA and MCP-1 respectively. Results: Gen significantly inhibited the expression of MCP-1 mRNA and MCP-1 in cell culture supernant . There was no significant difference in the inhibitory effect between high concentration of Gen and physiological level of 17b-E . Conclusion: Gen can down-regulate hUVSMC expression of MCP-1 mRNA and MCP-1. It suggests that this may be the important antiatherogenic mechanism of Gen.

Objective:To investigate the expressions of peroxisome proliferator-activated receptor gamma (PPARγ), estrogen re-ceptor alpha (ERα), and estrogen receptor beta (ERβ) in endometrial carcinoma and to analyze their correlations and clinical signifi-cance. Methods:Immunohistochemical assay and Western blot were used to detect the expressions of PPARγ, ERα, and ERβin normal endometrial tissues and well-differentiated, moderately differentiated, and poorly differentiated endometrial carcinomas. Results:PPARγexpression was significantly lower in endometrial carcinoma than in the normal endometrium and was intimately associated with cli-ni-copathologic variables. ERαexpression gradually decreased in moderately and poorly differenti-ated endometrial carcinomas. How-ever, no significant differences were found between the normal endometrium and well-differentiated endometrial carcinoma. ERβex-pression only decreased in the poorly differentiated endometrial carcinoma. No significant association was observed between ERβand clinicopathologic variables. Pearson correlation analysis showed a significant positive cor-relation between the expressions of PPARγand ERα. No correlations were observed between the expressions of ERαand ERβand between that of ERβand PPARγ. Conclusion:The expression lev-els of PPARγand ERαwere significantly associated with the clinicopathologic stage of endometrial carcinoma, and have essential functions in endometrial tumorigenesis and tumor progression.

Objective:To investigate the relationship between blood lipid level and low birth weight infants in late pregnancy.Methods:Data of 303 low birth weight newborns delivered in ShengJing Hospital affiliated to China Medical University were collected from January 2018 to February 2020, and 303 cases of full-term normal birth weight infants delivered in our hospital during the same period (birth weight 2500 ~ 3999 g) for retrospective study.The general situation of puerpera was analyzed, including age, gestational age, times of pregnancy, times of labor, weight growth during pregnancy, pre pregnancy body mass index, and blood lipid indexes of puerpera within one week before termination of pregnancy, including triglyceride, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, apolipoprotein A, apolipoprotein B.Results:The normal birth weight group was (31.60±3.90) years old, the weight gain during pregnancy was (16.29±5.31) kg, and the triglyceride levels was(3.21±1.33) mmol/L.The low birth weight group was (30.30±4.65) years old, the weight gain during pregnancy was (14.45±8.08) kg, and the triglyceride level was(2.88±1.37) mmol/L, and there were differences between groups( P<0.01). In the low term birth weight group, birth weight was negatively correlated with maternal age ( r=-0.24, P=0.01), positively correlated with gestational age ( r=0.24, P=0.02), and negatively correlated with pregnancy weight gain ( r=-0.26, P<0.01), and was positively correlated with triglyceride ( r=0.15, P=0.01) and total cholesterol ( r=0.20, P<0.01). Conclusion:The incidence of full-term low birth weight infants is closely related to the blood lipid level, age, gestational age at delivery and the growth of body weight during pregnancy.

Objective:To analyze the composition differences of intestinal microbiota in patients with colon cancer and rectal cancer.Methods:The fecal samples of 72 patients in the Second Affiliated Hospital of Harbin Medical University from July 2018 to January 2019 were collected, and they were divided into colon cancer group and rectal cancer group, 36 cases in each group. DNA from fecal samples was extracted, and then high-throughput sequencing was performed on DNA. Bioinformatics was used to analyze the diversity and composition differences of intestinal microbiota between the two groups, and the potential cancer-promoting mechanisms of the differential flora were also discussed.Results:From high-throughput sequencing, 2 356 560 original sequences and 32 730 high-quality sequences were obtained from 72 samples. The average length of the sample sequence was mainly in the interval of 401-460 bp. And 1 409 operational taxonomic units (OTU) were acquired after OTU species taxonomy annotation of all the sequences. Alpha diversity analysis showed that Shannon index of the rectal cancer group and the colon cancer group was 2.61±0.56 and 2.43±0.67, respectively, and the difference was statistically significant ( t = 1.229, P = 0.223); Simpson index of the rectal cancer group and the colon cancer group was 0.17±0.09 and 0.21±0.16, respectively, and the difference was statistically significant ( t = 1.449, P = 0.151). Differences analysis of both groups and linear discriminant analysis (LDA) showed at the phylum level, Firmicutes were more abundant in the intestine of patients with rectal cancer (LDA = 4.67, P = 0.014), while Proteobacteria were more abundant in the gut of colon cancer patients (LDA = 4.49, P = 0.042). From the perspective of class level, the abundance of Gammaproteobacteria was higher in the intestine of patients with colon cancer (LDA = 4.50, P = 0.033), while the abundance of Erysipelotrichia was higher in the intestine of patients with rectal cancer (LDA = 3.50, P = 0.035). At the order level, the abundance of Erysipelotrichales was higher in the intestine of patients with rectal cancer (LDA = 3.50, P = 0.035); at the family level, the abundance of Porphyromonadaceae was higher in the intestine of patients with rectal cancer (LDA = 3.97, P = 0.033). Conclusion:The compositions of intestinal microbiota in patients with colon cancer and rectal cancer are significantly different, indicating that the different floras may contribute to the progression of colon cancer and rectal cancer.
