Objective To evaluate the influence of different diagnostic criteria of gestational diabetes mellitus(GDM) using oral glucose tolerance test(OGTT) on pregnant outcome. Methods A retrospective study of women who delivered at Peking University First Hospital from Jan 1, 2001 to Dec 31,2003 was conducted. All women with abnormal 50 g oral glucose screening test received 75 g OGTT. Totally, there were 850 cases not being diagnosed as GDM or GIGT according to Fernando′s criteria and these women were divided to two groups according to Zhi guang DONG′s criteria: group Ⅰ included those who meet the criteria of GDM and GIGT and group Ⅱ included those who did not. Results The rate of abnormal OGTT was 23.76% (GDM 4.35%, GIGT 19.41,37 vs 165 cases). The average birth weight of group Ⅰ was significantly higher than that of group Ⅱ [(3461.4?475.9)g vs (3407.8?438.4) g, P

OBJECTIVETo explore the relationship between abnormal expressions of positive cell cycle control factors and thyroid carcinoma occurrence and progression, and assess the value of these factors in evaluating tumor cell proliferation activity and the prognosis of the patients.

METHODSImmunohistochemical SP method was used to detect the expressions of MCM7, CDK2 and Ki-67 proteins in 50 cases of thyroid carcinoma, 30 cases of thyroid adenoma, 30 cases of nodular goiter and 20 cases of normal thyroid gland tissues.

RESULTSThe positive rates of MCM7, CDK2 and Ki-67 expressions in thyroid carcinoma were 100% (50/50), 80.00% (40/50) and 84.00% (42/50), significantly higher than the rates in thyroid adenoma, nodular goiter and normal thyroid tissue (P<0.01). In thyroid carcinoma tissues, positive correlations were observed between the expressions of MCM7 and CDK2 proteins (r=0.637, P<0.01), MCM7 and Ki-67 proteins (r=0.633, P<0.01), and CDK2 and Ki-67 proteins (r=0.862, P<0.01).

CONCLUSIONThe high expressions of MCM7, CDK2 and Ki-67 protein may contribute to the development of thyroid carcinoma, and their combined examination may serve as useful index for early diagnosis and prognostic evaluation of thyroid carcinoma. MCM7 is superior to Ki-67 in the evaluation of the thyroid tumor cell proliferation activity.

Objective:To investigate the correlation between activities of daily living and hemoglobin level in patients with acute ischemic stroke (AIS).Methods:A retrospective analysis was performed in 190 patients with acute ischemic stroke from August 2015 to April 2017. The hemoglobin (Hb) levels at admission were analyzed . According to the Barthel index (BI) score, the patients were divided into good improvement group ( n=119) and poor improvement group ( n=71). Spearman correlation analysis was used to study the relationship between hemoglobin level and short-term activities of daily living in patients with acute ischemic stroke. Results:(1)The short-term activities of daily living was improved in 119 patients. Among them, 62 (52.1%) were under 65 years old and 57 (47.9%) were over 65 years old, 9 (7.56%) male patients with hemoglobin <120 g/L and 39 (32.77%) male patients with hemoglobin > 150 g/L. There were 71 patients with poor short-term activities of daily living. Among them, 23(32.39%)were under 65 years old and 48(67.61%)were over 65 years old, 1(1.41%)male patients with hemoglobin <120 g/L and 12(16.9%) male patients with hemoglobin > 150 g/L. There were significant differences in age (χ 2= 6.985, P=0.008) and male hemoglobin level (χ 2= 8.069, P=0.005) between patients with good activities of daily living and patients with poor activities of daily living.(2)Regression analysis showed that age > 65 years ( β =1.386, OR=4.000, 95% CI=1.189-3.461, P=0.025) and abnormal hemoglobin levels in men (Hb<120 g/L or > 150 g/L) ( β =1.089, OR=2.972, 95% CI=1.383-6.388, P=0.005) were the influencing factors of poor short-term quality of life in patients with acute ischemic stroke.(3)Spearman correlation analysis showed that abnormal hemoglobin levels in men (Hb<120 g/L or>150 g/L) were positively correlated with poor short-term activities of daily living in patients with acute ischemic stroke( r=0.244, P=0.004). Conclusion:Abnormal hemoglobin level is associated with poor short-term activities of daily living improvement in patients with acute ischemic stroke.

Objective:To investigate the correlation between serum 25-hydroxyvitamin D (serum 25(OH)D) and Meige syndrome.Methods:A retrospective analysis was performed on 47 patients with Meige syndrome (Meige syndrome group) treated in Yuquan Hospital of Tsinghua University admitted from August 2012 to July 2018 in our hospital.In the same period, 69 healthy people of the same age group were selected as the healthy control group.The difference of serum 25(OH)D concentration among different subtypes of Meige syndrome (type I, II, III) was compared.Logistic regression analysis was used to analyze the correlation between serum 25(OH)D level and Meige syndrome.Results:The serum 25(OH)D concentration in patients with Meige syndrome was (12.68±6.77) μg/L, which was significantly lower than that in the healthy control group ((17.93±6.93) μg/L). The difference was statistically significant ( t=4.044, P<0.001). The serum 25(OH)D concentrations of subtypes I, II and III in patients with Meige syndrome were (14.7±8.14), (11.4±5.02), (8.38±4.99) μg/L, respectively. There was no significant difference among the three types ( F=1.892, P=0.231). Logistic regression results showed that serum 25(OH)D levels were correlated with Meige syndrome ( OR=0.938, 95% CI: 0.885-0.995, P=0.034). Conclusion:The serum 25(OH)D expression level in patients with Meige syndrome is low, suggesting that vitamin D deficiency may be involved in the pathogenesis of Meige syndrome.

Objective:To develop the Care Needs Scale for Young and Middle-aged Terminally Ill Patients and test its reliability and validity, so as to provide an effective tool for evaluating the care needs of young and middle-aged terminally ill patients for medical and nursing staff.Methods:This study is a cross-sectional study. Guided by the theory of supportive care needs, an initial scale was formed through literature review, qualitative interviews, Delphi expert consultation, and pre-survey. From July to September 2022, convenience sampling was used to select 570 young and middle-aged terminally ill patients hospitalized in the Oncology Department and Hospice Care Ward of six Class Ⅲ hospitals in Tianjin as the research subject, and a questionnaire survey was conducted on the patients. The items in the scale were selected using item analysis method. The structural validity of the scale was evaluated using exploratory factor analysis and confirmatory factor analysis. The content validity of the scale was evaluated using the scale-level content validity index and the item-level content validity index. The reliability of the scale was evaluated using internal consistency coefficient and half reliability coefficient. A total of 570 questionnaires were distributed, and 565 valid questionnaires were collected, with an effective response rate of 99.12% (565/570) .Results:A total of 18 experts completed two rounds of consultation, with an expert authority coefficient of 0.890, the Kendall's W values of 0.309 and 0.417, respectively ( P<0.05). The Care Needs Scale for Young and Middle-aged Terminally Ill Patients included 6 dimensions and a total of 39 items. Exploratory factor analysis extracted 6 common factors, with a cumulative variance contribution rate of 71.515%. Confirmatory factor analysis showed that the overall model fitted well. The content validity index at the scale level was 0.942, and the content validity index at the item level was 0.833 to 1.000. The total Cronbach's α coefficient of the scale was 0.975, and the half reliability coefficient was 0.911. Conclusions:The reliability and validity of the Care Needs Scale for Young and Middle-aged Terminally Ill Patients are good, and it can be used as an evaluation tool for the care needs of young and middle-aged terminally ill patients.

Objective:To investigate the implication of micro RNA-21(miR-21) in Endostar combined with X-ray irradiation of cardiac fibroblasts (CF).Methods:Rat CFs were used in this experiment and been divided into the blank control group, 10 Gy X-ray irradiation group, Endostar group, 10 Gy X-ray+ Endostar group, 10 Gy X-ray+ Endostar+ NC mimic group (negative control 1), 10 Gy X-ray+ Endostar+ miR-21 mimic group, 10 Gy X-ray+ Endostar+ NC inhibitor group (negative control 2) and 10 Gy X-ray+ Endostar+ miR-21 inhibitor group. The proliferation of CF was determined by Methyl thiazolyl tetrazolium (MTT) assay. The expression level of Collagen Ⅰ protein was analyzed by Western blot. The expression levels of Collagen Ⅰ and miR-21 mRNA were assayed by real-time quantitative polymerase chain reaction (q-PCR).Results:In the 10 Gy X-ray+ Endostar+ miR-21 mimic group, the CF proliferation, Collagen Ⅰ and miR-21 mRNA were increased significantly compared with those in the blank control group, 10 Gy X-ray+ Endostar group, and negative control group 1 (all P<0.05). In the 10 Gy X-ray+ Endostar+ miR-21 inhibitor group, the CF proliferation and expression levels of Collagen Ⅰ mRNA were decreased significantly compared with those in the blank control group, 10 Gy X-ray+ Endostar group and negative control group 2(all P<0.05). Conclusions:The CF proliferation and Collagen Ⅰ expression are increased when the expression level of miR-21 gene is simulated. When inhibiting the expression of miR-21 gene, the CF proliferation and Collagen Ⅰ expression are reduced.
