Objective To develop and test the reliability and validity of the Intrinsic Capacity Assessment Scale for the Older People,so as to provide an effective tool for the assessment of the intrinsic capacity of the aged.Methods Based on the International Classification of Functioning,Disability and Health(ICF)as the theoretical framework,the initial version of The Intrinsic Capacity Assessment Scale for the Older People was developed through literature analysis,Delphi expert consultation and pre-survey.From July to September 2023,650 old people were selected by convenience sampling method to conduct a survey,and 20 old people were surveyed after 2 weeks again to test the reliability and validity of the scale.Results The effective questionnaire recovery rates of the 2 rounds of expert correspondence were 92.3％and 91.7％;the expert authority coefficients were 0.83 and 0.86;the mean importance scores of items were 2.04-3.79 and 3.50-3.82,and the full score ratios were 4.2％-83.3％and 54.6％-86.4％,respectively.The coefficients of variation were 0.11-0.42 and 0.11-0.23,respectively.A total of 5 common factors were extracted from exploratory factor analysis,and the cumulative variance contribution rate was 68.327％.The results of confirmatory factor analysis showed that the fit indexes were x2/df=1.908,RMSEA=0.054,CFI=0.931,IFI=0.932,TLI=0.922,indicating a good fit.The Cronbach's α coefficient of the scale was 0.944;the split half reliability was 0.806;the retest reliability was 0.933.The content validity index of item level was 0.82-1.00,and the content validity index of scale level was 0.91.The Intrinsic Capacity Assessment Scale for the Older People included 35 items in 5 dimensions:movement,vitality,sensation,cognition and psychology.Conclusion The Intrinsic Capacity Assessment Scale for the Older People has good reliability and validity,and it can be used as a reliable tool to evaluate the intrinsic capacity level of the aged.

Objective: To systematically evaluate the incidence and influencing factors of depression in family caregivers of Alzheimer's disease (AD) patients, so as to provide the basis for the prevention and treatment of depression among the family caregivers of AD patients. Methods: Publications pertaining to depression in family caregivers of AD patients were retrieved from CNKI, Wanfang Data, PubMed and other databases from the time of their establishment to June 15, 2023. The evaluation criteria recommended by the Agency for Healthcare Research and Quality (AHRQ) and the Newcastle-Ottawa Scale were used to assess the quality of cross-sectional and cohort studies, respectively. Stata 16.0 and Revman 5.4 softwares were used to conduct a meta-analysis on the incidence and influencing factors of depression in family caregivers of AD patients. Sensitivity analysis and publication bias assessment were also performed on the results. Results: A total of 2 324 articles were retrieved, and ultimately 14 articles were included, with a total sample size of 8 313 individuals. There were 6 high-quality articles and 8 moderate-quality articles. Meta-analysis showed that the incidence of depression in family caregivers of AD patients was 37.5% (95%CI: 30.2%-45.1%). Factors associated with depression included patients' high degree of dementia (OR=1.718, 95%CI: 1.059-2.789), patients' low scores on Activities of Daily Living Scale (OR=1.344, 95%CI: 1.059-1.706), patients' psychobehavioral abnormalities (OR=1.248, 95%CI: 1.155-1.348), long duration of caregiving (OR=1.998, 95%CI: 1.637-2.437), less involvement of other family members in caregiving (OR=1.597, 95%CI: 1.237-2.061), low educational level (OR=1.191, 95%CI: 1.044-1.359), poor caregiving skills (OR=3.060, 95%CI: 2.257-4.149), poor self-rated health (OR=2.536, 95%CI: 1.114-5.771) and social support (OR=0.424, 95%CI: 0.232-0.774). The results of depression incidence demonstrated good stability with no significant publication bias. However, publication bias was observed in the influencing factors for depression, which were patients' high degree of dementia and patients' low scores on Activities of Daily Living Scale. Conclusions The incidence of depression in family caregivers of AD patients ranges from 30.2% to 45.1%. It is primarily influenced by the severity of patients' symptoms and ability to perform daily activities, and caregivers' educational level, caregiving skills, health status, caregiving duration and social support.

Objective·To study the hemodynamic parameters of uterine at midluteal phase in patients with early recurrent spontaneous abortion (ERSA) and the effect of aspirin on them. Methods·Transvaginal color Doppler ultrasonography was used to measure the parameters of uterine blood flow and the endometrial thickness at midluteal phase of 271 women with ERSA (ERSA group) and 66 women without a history of recurrent spontaneous abortion (control group). Then ERSA group were administered with aspirin 50 mg/d orally for 2 months and other individualized treatment, and the effect of aspirin on parameters of uterine blood flow and the early pregnancy outcome of them were observed. Results·At midluteal phase, the endometrium was significantly thinner in ERSA group than that in control group. Pulsatility index (PI) of endometrial blood flow and mean PI (mPI), mean resistance index (mRI), and mean systolic/diastolic ratio value (mS/D) of uterine arteries were statistically significantly higher in ERSA group in comparison to control group (P<0.05). Following aspirin treatment, resistance to uterine blood flow reduced significantly in ERSA group (P=0.000), and the endometrial thickness increased in the patients with endometrial thickness less than 7 mm (P=0.000). Only 163 ERSA patients were re-examined by transvaginal color Doppler ultrasonography after aspirin treatment, among whom 136 women was pregnant after individualized treatment. Among these pregnant patients, 97 cases were pregnant for more than or equal to 12 weeks, while 10 cases aborted during the first 12 weeks, and the early pregnancy outcomes of the other 29 cases were still unclear. Conclusion·In comparison with normal fertile women, ERSA patients have significantly higher resistance to uterine blood flow and thinner endometrium. Aspirin can improve uterine blood perfusion, which improves early pregnancy outcome.

Objective · To investigate the status of depression and anxiety in patients with recurrent spontaneous abortion (RSA) and the possible influence factors and to provide theoretical support for further psychological intervention. Methods · RSA patients and women with no history of RSA were invited to complete a questionnaire, including basic information, Self-Rating Depression Scale (SDS) and Self-Rating Anxiety Scale (SAS). All data were analyzed by SPSS. Results · Of all 1064 cases included in this study, 725 were RSA cases, 217 cases with one spontaneous abortion and 122 in control group with no history of spontaneous abortion. Our results showed that both RSA patients and patients with one spontaneous abortion have significantly higher SDS and SAS scores than control group. Furthermore, non-pregnant RSA patients with lower education level, lower household income and 3-5 years of marriage have significantly higher levels of depression and anxiety. Patients with multiple miscarriages (≥4), history of induced abortion and no live birth, score significantly higher in SDS. Conclusion · Whether pregnant or not, RSA patients are much easier to become depressive and anxious, which may be associated with education level, household income, length of marriage, numbers of pregnancy losses and previous live birth. Women with one spontaneous abortion also show a significant higher tendency of depression and anxiety. These patients should be given proper psychological intervention if necessary.

Objective To analyze the current status and the issues of alexithymia's nursing in China to provide references for further research in this area.Methods CNKI, Wanfang, VIP, CBM, PubMed and CINAHL databases were screened for published papers on alexithymia's nursing in China from their inauguration to 30th September 2016. Bibliometric data were extracted and analyzed using metrological analysis.Results A total of 84 papers were included. The first paper was published in 2001. The amount of the literature increased annually after 2009. Papers were mainly from the central and eastern regions and lack of foundation. The major papers were descriptive studies and accounted for 59.52%. The main topic was investigation of correlations between alexithymia and psychosomatic symptoms and symptoms of disease, which accounted for 48.84%. Subjects in the study were mainly patients with chronic diseases with a rate of 23.81%. In 23 included clinical trials, alexithymia's nursing was mainly performed in forms of group psychological counseling with a rate of 26.09%. The less common form was realization social support which accounted for 17.39%. The evaluation parameters contained 78.26% of functional indexes of patients and 21.74% of clinical outcome indicators.Conclusions The published papers are in small amount and with low quality. It is necessary to expand the studies on the specialized diseases and establish multi-dimension nursing model based on the combination of nursing theory and clinical practice.

Objective To investigate the serum cystatin C(Cys C)levles in different age and sex health physical examination people,and to analyze the correlation between different ages,different genders and Cys C levles. Methods 648 healthy subjects checked with physical examination were selected.611 patients with normal renal function were selected.The serum Cys C and Cr concentrations were determined and statistically analyzed according to different age or gender groups.The serum Cys C and Cr concentrations of other 37 patients with abnormal renal func-tion were detected and compared with normal renal function people in the same ages.Results There were no signifi-cant differences in serum CysC levels between men and women in different ages and normal renal function people(t =2.449,P =0.092;t =0.176,P =0.872;t =2.030,P =0.135;t =2.376,P =0.098;t =1.549,P =0.219;t =1.732,P =0.182;t =1.095,P =0.353;t =1.732,P =0.182;t =2.449,P =0.092;t =2.611;P =0.080).There were significant differences in serum Cys C level between men,women and combined with normal renal function(F =5.662,5.615,7.253,all P <0.05).Taken the linear correlation analysis by age with serum Cys C level among men, women and combined with normal renal function groups,the results showed that had positive correlation(r =0.525, 0.511,0.522,all P <0.05 ).Renal function of different genders in the health physical examination people over 50 years of age appeared serum Cys C positive persons,and the positive rate of each gender group increased alone with the increase of age(F =7.324,7.341,7.452,all P <0.05).The Cys C,Cr content and positive rate of renal function in health physical examination people were significantly lower than abnormal renal function people (t =31.080, 15.472;χ2 =17.043,34.105;all P <0.05).Conclusion There is an evident positive correlation in health physical examination people between serum Cys C level and the ages,and are increased alone with increase of age,which is increasing evidently alone with increase of age,while has no correlation with gender.

Objective To analyze the mammographic features of invasive lobular carcinoma (ILC)compared to those of invasive ductal carcinoma (IDC).Methods Twenty cases with ILC and 95 cases with IDC were retrospectively evaluated by two breast radi-ologists according to the Breast Imaging Reporting and Data System (BI-RADS)lexicon.The mammographic findings were com-pared between ILC and IDC with the independent samples chi-square test or Fisher’s exact test,as appropriate.Results Mass was the most common finding in both ILCs and IDCs,but less frequent in ILCs (36.4% vs 63.9%,P =0.008).Mass in ILCs was more frequently lobular or irregular shape with spiculated margin.Architectural distortion and focal asymmetry were more frequent in ILCs than in IDCs,however,the differences were no significant.The frequency of calcifications was not significantly different between the two groups.The distributions of calcifications were more regional in ILCs,and more segmental or linear in IDCs (P =0.01).Conclu-sion ILCs are more usually shown as non-mass appearances on mammography.ILCs that appeared as mass are more frequently ir-regular in shape with spiculated margins.

Objective To study the role of expressions of vascular endothelial growth factor C (VEGF-C), vascular endothelial growth factor receptor-3 (VEGFR-3) and lymphatic vessel hyaluronan receptor-1(LYVE-1) on the lymphangio-genesis and prognosis in gastric cancer. Methods The tissue microarray technology was used to detect the expressions of VEGF-C, VEGFR-3 and LYVE-1 in 125 gastric cancer specimens, 96 adjacent normal tissues and 20 benign gastric lesion samples. The lymphatic vessel density (LVD) marked by Podoplanin was detected as well. Results The positive rates of VEGF-C, VEGFR-3 and LYVE-1 in gastric cancer tissues were 62.4%, 56.0%and 58.4%, which were significantly higher than those in adjacent normal tissues (10.4%,12.5%and 9.4%) and benign gastric lesion tissues (20%, 30%and 25%, P<0.05). The LVD score was significantly higher in gastric intra-tumoral and peri-tumoral samples (2.98±0.81 and 4.22±1.09) than that in adjacent normal tissues or benign gastric lesion samples (1.82±0.63 or 0.89±0.45, P<0.01). The LVD score was significantly higher in peri-tumoral samples than that of intra-tumoral samples (P<0.01). There was a positive relationship between expression levels of VEGF-C,VEGFR-3 and LYVE-1 with LVD (P<0.05). The positive expressions of the three indexes were the risk factors of lymph node metastasis and distant metastasis (P<0.05). There was a significantly longer 5-year survival rate in patients with negative expression of the three indexes (P<0.05). Conclusion VEGF-C, VEGFR-3 and LYVE-1 proteins were positively highly expressed in gastric cancer tissues, which were risk factors affecting the progno-sis of gastric cancer. The expression levels of the three indexes can be used to predict the prognosis and lymphangiogenesis of gastric cancer.
