Objective To explore the diagnosis value of expression level of peripheral blood microRNA-21 in early gastric cancer patients. Methods In 52 patients with Tis gastric cancer and 40 healthy subjects, expression levels of microRNA-21 in peripheral blood were quantitatively detected by real-time quantitative PCR(qRT-PCR),and diagnostic value of expression level of microRNA-21 in peripheral blood were evaluated by receiver operator characteristic (ROC) curve. Results Relative quantity expression level of microRNA-21 in peripheral blood in gastric cancer group and healthy subjects group were 2.286±0.592 and 1.318±0.357, and there was statistical significance (U=136.500, P=0.000). ROC curve analysis showed that ROC curve area of expression level of microRNA-21 in peripheral blood in diagnosing gastric cancer was 0.934(95%CI 0.887-0.982, P=0.000), and the best diagnostic boundary point value was 1.912. The sensitivity of expression level of microRNA-21 in peripheral blood in diagnosing gastric cancer was 86.5%, and the specificity was 95.0%. Conclusion Expression level of microRNA-21 in peripheral blood has important diagnostic value in early gastric cancer.

Objective To investigate the curative effects and adverse reactions of pure radiotherapy and concurrent chemotherapy and radiotherapy for patients with cervical cancer.Methods One hundred and twenty-seven patients with cervical cancer who accepted treatment in the Affliated Hospital of Inner Mongolia Medical Unive.rsity from May 2010 to May 2012 were collected.All patients were divided into two groups:pure radiotherapy group (n =65) and concurrent chemotherapy and radiotherapy group (n =62).The curative effects,adverse reactions and survival of two groups were observed.Results All patients were completed treatment.The median follow-up time was 42 months.The rate of complete response in the pure radiotherapy group was 80.0％ (52/65),and the rate in the concurrent chemotherapy and radiotherapy group was 82.26％ (51/62),with no significant difference (x2 =1.22,P =0.352).The 1-year overall survival rates in the pure radiotherapy group and the concurrent chemotherapy and radiotherapy group were 95.38％ and 95.16％ respectively,with no significant difference (x2 =0.32,P =0.533),but the 3-year overall survival rates were 81.54％ and 90.32％ respectively,the 5-year overall survival rates were 72.31％ and 83.87％ respectively,with significant differences (x2 =5.09,P =0.015;x2=3.87,P =0.039).However,for the patients who were ≥ 60 years,the 1-year overall survival rates in the two groups were 94.62％ and 93.91％ respectively,the 3-year overall survival rates were 85.02％ and 87.25％ respectively,the 5-year overall survival rates were 70.06％ and 73.58％ respectively,with no significant differences (x2 =0.06,P =0.753;x2 =1.16,P =0.279;x2 =0.48,P =0.511).The adverse reactions were mainly in grades 1-2.There were significant differences in the rates of leucopenia (56.10％ vs.72.20％),thrombocytopenia (58.82％ vs.76.80％),nausea and vomiting (34.04％ vs.56.90％) among the two treatment groups (x2 =11.23,P =0.003;x2 =11.82,P=0.002;x2 =12.77,P =0.000).Conclusion The curative effect of concurrent chemotherapy and radiotherapy is better than that with pure radiotherapy for patients with cervical cancer,which can improve the 3-year and 5-year overall survival.But at the same time,it should be noted that the rates of adverse reactions may be increased during the same period.For the age of 60 or more patients with cervical cancer,concurrent chemotherapy and radiotherapy does not achieve even greater survival benefit.

Objective To analyze the relationship between cytotoxic T cells Perforin level, IFN-γand IL-10 in patients with chronic hepatitis B. Methods After a short-term cultivation of peripheral blood collected from 50 patients with chronic hepatitis B, a flow cytometry was employed to detect the levels of Per-forin, IFN-γ and IL-10 in CD8~+ cells to compare with those of the health donors the HBV DNA copies in their blood were also measured by RT-PCR to analyze the relationship with Perforin, IFN-γ, and IL-10 in CD8~+ cells. Results In patients with chronic hepatitis B, the levels of Perforin, IFN-γ and IL-10 in CD8~+ ceils were (5.30 ± 2.62)%, (4.05 ± 2.25) % and (0.77 ± 0.50) %, respectively, which were statistical-ly lower than health donors(the t values were 4.50, 4.56 and 4.20 respectively; P < 0.01) ; Of 26 cases of chronic hepatitis B patients with HBeAg-positive Pefforin and IFN-γ in CD8~+ T cells were (4.54 ± 1.93) % and (3.32 ± 1.59)%, respectively, significantly lower than those of the 24 chronic hepatitis B patients with HBeAg-negative (the t values were 2.22 and 2.54, respectively; P <0.05) ; And the levels of Perforin, IFN-γ had a negative relation with the HBV DNA copies (the coefficient correlations-0. 539 and-0. 340; P < 0.01 and P < 0.05). Conclusion In patients with chronic hepatitis B, the reduced levels of Pefforin, IFN-γ and IL-10 may be related with the long-term existence of HBV, and the protracted course of disease.

Objective To investigate the HBV- positive pregnant women about the knowledge of the route of hepatitis B transmission, hepatitis B hazards, health care during pregnancy, announcements of child- care to explore targeted and effective health education model with self- designed question-naires. Methods Nurses in obstetrics department carried out this questionnaire investigation in the outpa-tients of HBV- positive pregnant women, after that the results underwent statistic analysis. Results The overall knowledge of HBV- positive pregnant women in announcements of child- care, health care during pregnancy and hepatitis B hazards was not very well, and the announcements of child- care was the lowest, followed by health care during pregnancy and hepatitis B hazards. The route of hepatitis B transmission was better, but still not satisfactory. The education should highlight these areas. Well- educated women were better than those who lack education. The age between 20 to 30 years old was better. Conclusions The HBV-positive pregnant women is lack of heath knowledge, so we should gave health intervention in a multi- level, multi- stage standardized and a variety of ways.

Objective:To explore the levels of serum adiponectin,insulin growth factor Ⅰ (IGF-Ⅰ) and prealbumin in preterm infants,and analyze their correlation with preterm EUGR infant.Methods:321 cases of preterm infants who were born in our hospital and transferred to neonatal department in 24 hours from January,2014 to January,2016 were enrolled in the present study.According to the weight at discharge,they were divided into the EUGR group and the non EUGR group,the growth and development as well as the levels of serum adiponectin,IGF-Ⅰ and PA in the two groups were compared.Results:The occurrence rate of EUGR was 55.76％ (179/321) in the 321 cases ofpreterm infants;the weight of EUGR group was significantly lower than that of the non EUGR group at 42 th days and three months after birth(p＜0.05).The SDS of both groups were all negative,and that of EUGR group was significantly lower than non EUGR group (p＜0.05).The levels of serum adiponectin,IGF-Ⅰ and PA of both groups were significantly lower than the control group at seventh days of birth,and the PA level of EUGR group was significantly lower than non EUGR group (p＜0.05).There was no significant difference in the serum adiponectin and PA levels between 7 days and 14 days in EUGR group (P ＞ 0.05),however,the serum adiponectin and PA levels in the non EUGR group was obviously increased and significantly higher than that of the EUGR group (p ＜ 0.05).The level of IGF-Ⅰ in both groups keep unchanged during two weeks (P＞0.05).Conclusion:The lower levels of serum adiponectin,IGF-Ⅰ and PA were closely related to the EUGR of preterm infants,which could be used as biochemical indexes to early diagnosis of EUGR.

Objective To assess the morphological characteristics of bone marrow in patients of severe fever with thrombocytopenia syndrome ( SFTS) and its value in diagnosis.Methods The bone marrow morphology was retrospectively reviewed in 28 laboratory confirmed patients with SFTS from Zhoushan Hospital during January 2012 and December 2015.The correlation between bone marrow -derived macrophage and peripheral blood cells was analyzed with t test.Results All patients presented leukocytopenia and thrombocytopenia.Poor bone marrow hematopoietic function was observed in 23 patients (82%) showing granulocyte, erythrocyte and megakaryocyte hypoplasia , but no pathological hematopoietic disorder was observed.Eighteen patients (64%) had various degrees of increased amount of macrophage in the bone marrow; peripheral white blood cell count and platelets in patients with macrophage ≥0.5% were lower than those with macrophage <0.5%, and the difference was of statistical significance (t =3.836 and 4.499, P<0.01).Conclusion SFTS patients have characteristic bone marrow morphology , and bone marrow examination is beneficial for differentiation of SFTS from blood lymphatic system diseases and other virus infection.

Objective:To investigate the effects of acupoint massage on cognitive function and sleep quality in elderly patients with hypertension. Methods:A total of 68 elderly patients with hypertension were enrolled, and their ages were all over 60 years old. They were divided into a control group and a treatment group by simple random method, with 34 cases in each group. Patients in the control group were treated by routine psychological health guidance and sleep knowledge education, while patients in the treatment group were treated by acupoint massage on the base of the interventions given to the control group. Both of their treatment courses were 3 months. Pittsburgh sleep quality index (PSQI) scores and mini-mental state examination (MMSE) scores before and after treatment were recorded and compared. Results:Two groups’ PSQI scores before treatment had no significant difference (P>0.05). After 3 months of treatment, their PSQI scores were statistically different (P<0.05). There was also no between-group statistical difference in MMSE score before treatment (P>0.05), but there was a significant difference after treatment (P<0.05). Conclusion:Acupoint massage for elderly patients with primary hypertension can improve their sleep quality and enhance their cognitive function, thus it is worthy of being applied in clinical nursing work.
