ABSTRACT

OBJECTIVE@#To explore the expression of Exosome Component 4(EXOSC4) in the tissues of newly diagnosed patients with diffuse large B-cell lymphoma (DLBCL) and its clinical significance.@*METHODS@#The expression of EXOSC4 protein in the tissues of 181 newly diagnosed DLBCL patients was analyzed by immunohistochemical staining. Clinical data were collected. The correlation between EXOSC4 protein expression in the tissues of newly diagnosed DLBCL patients and clinical features were analyzed and its prognostic significance.@*RESULTS@#The positive rate of EXOSC4 protein expression was 68.51% in the tissues of 181 newly diagnosed DLBCL patients. These patients were divided into two groups, with 44 cases in high expression group and 137 cases in low expression group. There were no significant differences in age, gender, B symptoms, serum lactate dehydrogenase (LDH) level, Eastern Cooperative Oncology Group (ECOG) score, Ann Arbor stage, extranodal disease, International Prognostic Index (IPI) score, National Comprehensive Cancer Network IPI (NCCN-IPI) score, and cell origin between the two groups (P>0.05). Cox multivariate regression analysis showed that high EXOSC4 protein expression in tissues was an independent poor prognostic factor for OS and PFS in newly diagnosed DLBCL patients (all P<0.05). K-M survival analysis showed that newly diagnosed DLBCL patients with high EXOSC4 protein expression had significantly shorter overall survival (OS) and progression free survival (PFS) than those patients with low EXOSC4 protein expression (all P<0.05).@*CONCLUSION@#High EXOSC4 protein expression in tissues of newly diagnosed DLBCL patients is an independent poor prognostic factor for survival.

ABSTRACT

OBJECTIVE@#To explore and verify the genes related to female peak bone mass(PBM) and osteoporosis (OP) based on bioinformatics.@*METHODS@#Using GEO data, DNA microarray technology to conduct genome-wide analysis of adult female monocytes with high and low PBM. Cluster analysis, GO enrichment and KEGG analysis were used to analyze the differential genes, and the interaction network of differential genes was further analyzed. OP rat model was established and femur neck tissue staining was performed to further verify the expression of differential genes.@*RESULTS@#A total of 283 genes were obtained by differential gene screening. Compared with the high PBM samples, 135 genes were up-regulated and 148 genes were down-regulated in the low PBM samples. A total of 7 pathways and 12 differential genes were enriched, and there were differences in the expression of several genes involved in mineral absorption and transport, cellular immunity and other aspects. Among them, voltage-gated Ca2+ channel 1.3(CaV1.3) encoded by CACNA1D gene was significantly enhanced in the femoral neck tissue of OP rat model.@*CONCLUSION@#The above results suggest that the difference in the expression level of CaV1.3 gene may lead to the occurrence of OP in women with low PBM, which provides us with a potential target for the prevention and treatment of OP.

ABSTRACT

Cellular immune responses as well as generalized and periarticular bone loss are the key pathogenic features of rheumatoid arthritis (RA). Under the pathological conditions of RA, dysregulated inflammation and immune processes tightly interact with skeletal system, resulting in pathological bone damage via inhibition of bone formation or induction of bone resorption. Single-cell omics technologies are revolutionary tools in the field of modern biological research.They enable the display of the state and function of cells in various environments from a single-cell resolution, thus making it conducive to identify the dysregulated molecular mechanisms of bone destruction in RA as well as the discovery of potential therapeutic targets and biomarkers. Here, we summarize the latest findings of single-cell omics technologies in osteoimmunology research in RA. These results suggest that single-cell omics have made significant contributions to transcriptomics and dynamics of specific cells involved in bone remodeling, providing a new direction for our understanding of cellular heterogeneity in the study of osteoimmunology in RA.

ABSTRACT

Objective: To investigate the humanistic care consciousness and ability of outpatient and emergency nurses in tertiary Grade A hospitals in Zhengzhou City. Methods: In June 2021, a total of 345 outpatient and emergency nurses from 6 tertiary Grade A hospitals in Zhengzhou City were selected as the survey objects by random number table method. The humanistic care ability of outpatient and emergency nurses was investigated. Multiple linear regression analysis was used to analyze the related factors influencing the humanistic care ability of outpatient and emergency nurses. Results: The total score of humanistic care ability of outpatient and emergency nurses in Zhengzhou tertiary Grade A hospital was (194.18±30.53). The scores of humanistic care ability of outpatient and emergency nurses with different gender, age, educational background, professional title, length of service, night shift frequency, marital status, children's status, employment patterns and average monthly household income were significantly different (P<0.05). Regression analysis showed that education background, length of service, professional title and night shift frequency were independent influencing factors for outpatient and emergency nurses' humanistic care ability (β=0.243, 0.139, 0.163, -0.126, P<0.05) . Conclusion: At present, the humanistic care ability of outpatient and emergency nurses in tertiary Grade A hospitals in Zhengzhou City is still low. Education, length of service, professional title and night shift frequency are independent influencing factors affecting the humanistic care ability of nurses.

ABSTRACT

Objective To understand the contamination status of common food-borne pathogens in foods sold in Changzhou, and to provide evidence for food safety risk assessment and prevention of food-borne diseases. Methods From 2010 to 2020 , 2 513 samples of 17 types of foods were collected in Changzhou area. The detection of pathogenic bacteria was carried out in accordance with the standard operation procedure specified in the “Workbook for Surveillance on Food Microorganisms and Pathogenic Factors in Jiangsu Province”. Results A total of 260 positive samples of common food-borne pathogens were detected in all 2 513 samples with an overall detection rate of 10.30%. Single factor analysis showed that the detection rate of pathogenic bacteria in non-ready-to-eat samples was higher than that in ready-to-eat samples (χ2=148.875,P =0.000). The detection rate of pathogenic bacteria in bulk samples was higher than that in prepackaged ones (χ2=70.956,P=0.000). There is a difference in the detection rate of food-borne pathogens from different types of sampling sites (χ2=65.017,P=0.000). Logistic regression analysis showed that ready-to-eat food, packaging type, and sampling season were significantly correlated with the detection rate of food-borne pathogens. The detection rate of pathogenic bacteria in samples collected in the third or fourth quarters was higher than that in the first quarter. Conclusion The commercial foods sold in Changzhou have a relatively high level of contamination of food-borne pathogenic bacteria, and they should be fully heated and sterilized before consumption. The relevant departments should strengthen supervision and health education in summer and autumn.

ABSTRACT

Objective To understand and analyze the epidemiological and pathogenic characteristics of foodborne diseases in Changzhou in the past five years, so as to provide evidence for prevention and control measures. Methods All foodborne disease surveillance information reported by Changzhou foodborne disease sentinel hospital from 2016 to 2020 was collected through the “Foodborne Disease Surveillance and Reporting System”. The distribution of reported cases and etiological results was described, and the possible factors affecting pathogen detection results were analyzed. Results A total of 14 931 cases of foodborne diseases were reported, mainly distributed in summer and autumn, and peaked in July and August. The age group of reported cases was 25-34 years old, and the occupations were mainly workers, and farmers and migrant workers, accounting for 23.2% and 36.9%, respectively. Among the reported cases of 3 120 anal swabs were collected and tested for etiology , of which 291 specimens were positive, with a positive detection rate of 9.32%. Among the 291 positive results of 118 cases of norovirus were detected, with a detection rate of 6.03% . 66 cases of salmonella were detected, with a detection rate of 2.12% . 25 cases of vibrio parahaemolyticus were detected, with a detection rate of 0.80% . 7 cases of diarrhea-causing Escherichia coli was detected, with a detection rate of 0.22% ; and 5 cases of shigella was detected, with a detection rate of 0.16% . Single factor analysis of the results of pathogen detection showed that there were no statistical differences in the distribution of positive pathogen detection rate between males and females, and between different suspicious exposed foods (all P>0.05). There were statistical differences in different age groups, occupations, seasons and eating places (all P<0.05). Multivariate Logistic regression analysis showed that age and season were correlated with the detection rates of pathogenic microorganisms (all P<0.05) , and age was negatively correlated with the positive rate of pathogenic microorganisms (OR=0.863). The detection rates in the first and fourth quarters were higher than those in the second and third quarters. Conclusion Summer and autumn are the seasons with high incidence of foodborne diseases in Changzhou. Norovirus is the main pathogen. Age and season are closely related to the detection results of pathogenic microorganisms. Comprehensive prevention and control measures should be implemented for key population in summer and autumn to reduce the occurrence and outbreak of foodborne diseases.

ABSTRACT

Objective: To study the incidence of bloodstream infections, pathogen distribution, and antibiotic resistance profile in patients with hematological malignancies. Methods: From January 2018 to December 2021, we retrospectively analyzed the clinical characteristics, pathogen distribution, and antibiotic resistance profiles of patients with malignant hematological diseases and bloodstream infections in the Department of Hematology, Nanfang Hospital, Southern Medical University. Results: A total of 582 incidences of bloodstream infections occurred in 22,717 inpatients. From 2018 to 2021, the incidence rates of bloodstream infections were 2.79%, 2.99%, 2.79%, and 2.02%, respectively. Five hundred ninety-nine types of bacteria were recovered from blood cultures, with 487 (81.3%) gram-negative bacteria, such as Klebsiella pneumonia, Escherichia coli, and Pseudomonas aeruginosa. Eighty-one (13.5%) were gram-positive bacteria, primarily Staphylococcus aureus, Staphylococcus epidermidis, and Enterococcus faecium, whereas the remaining 31 (5.2%) were fungi. Enterobacteriaceae resistance to carbapenems, piperacillin/tazobactam, cefoperazone sodium/sulbactam, and tigecycline were 11.0%, 15.3%, 15.4%, and 3.3%, with a descending trend year on year. Non-fermenters tolerated piperacillin/tazobactam, cefoperazone sodium/sulbactam, and quinolones at 29.6%, 13.3%, and 21.7%, respectively. However, only two gram-positive bacteria isolates were shown to be resistant to glycopeptide antibiotics. Conclusions: Bloodstream pathogens in hematological malignancies were broadly dispersed, most of which were gram-negative bacteria. Antibiotic resistance rates vary greatly between species. Our research serves as a valuable resource for the selection of empirical antibiotics.

ABSTRACT

Objective: This study aimed to investigate the prognostic significance of IKZF1 gene deletion in patients with acute B lymphoblastic leukemia (B-ALL) . Methods: The clinical data of 142 patients with B-ALL diagnosed in Nanfang Hospital between March 2016 and September 2019 were analyzed. Results: IKZF1 deletion was found in 36.0% of the 142 patients with B-ALL, whereas exon 4-7 deletion was found in 44.0% . White blood cell counts were higher in patients with the IKZF1 deletion (52.0% and 28.3% , P=0.005) ; these patients also experienced worse effects of mid-term induction therapy (40.0% and 70.7% , P<0.001) and had a higher proportion of Philadelphia chromosome-positive (52.0% and 21.7% , respectively, P<0.001) . Univariate analysis revealed that the 3-year overall survival rate (OS) and event-free survival rate (EFS) in the IKZF1 deletion group were significantly lower than the IKZF1 wild-type group [ (37.1±7.3) % vs (54.7±5.4) % , (51.8±7.9) % vs (73.9±4.7) % ; P=0.025, 0.013, respectively]. Multivariable analysis showed that harboring IKZF1 deletion was an adverse factor of EFS and OS (HR=1.744, 2.036; P=0.022, 0.020, respectively) . Furthermore, the IKZF1 deletion/chemotherapy group had significantly lower 3-year OS, EFS, and disease-free survival rates than other subgroups. In the IKZF1 deletion cohort, allo-hematopoietic stem cell transplantation (HSCT) significantly improved OS and EFS compared to non-allo-HSCT[ (67.9±10.4) % vs (31.9±11.0) % , (46.6±10.5) % vs (26.7±9.7) % ; P=0.005, 0.026, respectively]. Conclusion: Pediatric-inspired chemotherapy was unable to completely reverse the negative effect of IKZF1 deletion on prognosis. Pediatric-inspired regimen therapy combined with allo-HSCT, in contrast, significantly improved the overall prognosis of IKZF1 deletion B-ALL.

ABSTRACT

Objective:To explore the expression features of cytochrome C oxidase subunit Ⅰ (MT-CO1), BCL2 interacting protein 3 (BNIP3) and interleukin (IL)-1β in the liver of MRL/lpr lupus mice.Methods:The mRNA and protein levels of MT-CO1, BNIP3, IL-1β, p16 and p21 in lupus mice and control mice were detected by polymerase chain reaction (PCR) and Western blot, the IL-1β expression site were detected by hematoxylin and eosin (HE) staining and immunohistochemical method, and themalondialdehyde (MDA) was detected by colorimetry. Hepatocytes and macrophages were stimulated with lipopolysaccharide (LPS), while hepatocytes were also cultured with supernatants obtained after macrophages stimulated with LPS, and the mRNA and protein levels of MT-CO1, BNIP3 and LC3B, as well as p16 and p21 expression, were determined by qPCR and Western blot. The expression of mitochondrial reactive oxygen species (mtROS) was detected by immunofluorescence. One way Analysis of Variance (ANOVA) was used to compare the mean of each group, and LSD method was used to compare the means of multiple samples, and Tamhane's T2 method was used to compare the means of multiple samples when the variance was uniform. Results:The results of PCR showed that the mRNA levels of MT-CO1 and BNIP3 in the liver tissue of the lupus group (0.14±0.04; 0.16±0.05) were significantly lower than those of the control group (0.11±0.04; 0.16±0.06), and the differences were statistically significant ( t=7.16, P<0.001; t=4.54, P<0.001). The expression levels of IL-1β, p16 and p21 in the lupus group (2.06±0.69; 0.37±0.14; 0.16±0.06) were significantly higher than those of the control group (0.23±0.06; 0.25±0.08; 0.11±0.04) ( t=9.58, P<0.001; t=24.35, P<0.001; t=22.36, P<0.001). The results of Western blot were consistent with those of PCR. HE staining showed lymphocyte infiltration in the liver tissue of lupus mice, and immunohistochemistry showed IL-1β in the liver tissue of lupus mice. The positive cells were mainly concentrated in the sinusoids, and the expression of hepatic parenchymal cells was not rearkable. The content of MDA in liver tissue of the lupus group (0.19±0.10) was higher than that of the control group (0.17±0.09), and the difference was statistically significant ( t=4.33, P=0.005). LPS directly stimulated AML12 hepatocytes (0.069±0.028; 0.17±0.07). The PCR results showed that compared with the control group (0.176±0.072; 0.08±0.03), the expression of MT-CO1, and BNIP3 were not significantly different ( t=1.01, P=0.337; t=0.88, P=0.399). The expression of IL-1β was significantly higher when incubated with the supernatants of LPS stimulated macrophages (0.28±0.09) compared than that of the control group (0.15±0.05) ( t=28.26, P<0.001). The results of PCR showed that the mRNA levels of MT-CO1 and BNIP3 in the LPS stimulated group (0.046±0.026; 0.17±0.05) were significantly lower than those in the control group (0.143±0.083; 0.18±0.06), and the differences were statistically significant ( t=7.52, P<0.001; t=4.24, P<0.001), The expression of p16 and p21 in LPS stimulated group (0.29±0.09; 0.27±0.09) were significantly higher than those in the control group (0.18±0.06; 0.22±0.07) ( t=13.54, P<0.001; t=8.69, P<0.001). The results of Western blot were consistent with those of PCR. Immunofluorescence showed that the fluorescence intensity of mtROS in LPS stimulated group (0.25±0.10) was higher than that in the control group (0.08±0.03), and the difference was statistically significant ( t= 4.86, P<0.001). Conclusion:Immune-mediated inflammation in the liver tissue of lupus mice can stimulate liver parenchymal cells to cause intracellular mitochondrial dysfunction. However, the mechanism of liver organ damage in lupus mice is not limited to the immune-mediated inflammation of immune active cells, but also include parenchymal cell mitochondrial dysfunction.

ABSTRACT

OBJECTIVE Only limited number of drugs are currently available for treating ischemic stroke. Therapeu?tic angiogenesis has recently emerged as one of the most promising therapies for cerebral ischemic injury. Isopropyl-β-(3,4-dihydroxyphenyl)-α-hydroxypropanoate (IDHP) is a metabolite derived from the botanical formulation for Dantonic?. Here, we investigated the angiogenic efficacy of IDHP in cerebral ischemia. METHODS The in vivo effects of IDHP were evaluated in the C57BL/6 mouse Matrigel plug and rat transient middle cerebral artery occlusion (tMCAO) models. Primary human umbilical vein endothelial cells (HUVEC) and human brain microvascular endothelial cells (HBMEC) were used to explore the effects of IDHP on stimulating proliferation, migration and tube formation in vitro. ELISA and Western blotting were used to quantitate the release and expression of relevant target molecules and signaling path?ways. RESULTS IDHP reduced infarct volume and improved sensorimotor function in rats subjected to tMCAO by pro?moting angiogenesis, and promoted Matrigel neovascularization in mice. Moreover, IDHP produced a biphasic modula?tion on proliferation and migration both in HUVEC and HBMEC. It also induced tube formation in a 12-day HUVEC-HDF co-culture model and in Matrigel assays. IDHP-induced angiogenesis was accompanied by increased levels of p-AMPKα (Thr172) and p-eNOS (Ser1177) both in vitro and in vivo, and the decreased level of VEGF in rat brains on day 1 whereas enhanced level of VEGF on day 3 and 7 after tMCAO. Mechanistically, AMPK knockdown or pharmacologi?cally inhibiting AMPK and its upstream kinases (CaMKKβ) inhibited the eNOS phosphorylation induced by IDHP in HUVEC. Furthermore, selective eNOS inhibitor (L-NIO), selective CaMKKβ inhibitor (STO) and AMPKa inhibitor (Com?pound C) blocked the capillary-like tube formation in the co-culture model induced by IDHP (10 nmol · L-1). CONCLU?SION Collectively, these findings showed that IDHP protected rats from cerebral ischemia-reperfusion injury by promot?ing angiogenesis via activating CaMKKβ/AMPK(Thr172)/eNOS(Ser1177) signaling, and suggest it to be a promising new drug candidate for the prevention and/or treatment of cerebral ischemia and other vascular occlusive diseases.

ABSTRACT

OBJECTIVE@#To investigate the clinical characteristics and prognosis of patients with medium and high risk myelodysplastic syndrome (MDS).@*METHODS@#97 MDS patients above the age of 60 treated in Nanfang Hospital, Southern Medical University from February 2011 to August 2020 were enrolled. The clinical characteristics and prognosis of the MDS patients with medium risk, high risk or very high risk based on IPSS-R category were retrospectively analyzed. According to the difference of treatment regimes, the patients were divided into the transplantation group, chemotherapy group and other treatment group, and the efficacy among the patients in the 3 groups were analyzed.@*RESULTS@#MDS with excess blast (MDS-EB) in the elderly patients with medium and high risk MDS were the most common, 47.4% of the patients with abnormal chromosome karyotypes, and 23.7% with complex karyotypes (≥3). 97.3% of the patients showed at least one gene mutation, and TP53 mutations were detected in nearly 20% of the patients with medium and high risk. Multivariate analysis showed that IPSS-R category and treatment regimes were the factors affecting the prognosis of elderly patients with medium and high risk MDS. The median overall survival (OS) time of the patients in the 3 groups showed significant difference (P=0.012), and the median OS of the patients in the transplantation group was significantly longer than that in the chemotherapy group and other group (P=0.003,P=0.014,respectively), while there was no significant difference in median OS between chemotherapy group and other treatment group (P=0.685).@*CONCLUSION@#Elderly MDS patients with medium and high risk can benefit from allogeneic hematopoietic stem cell transplantation, which will prolong their OS.

ABSTRACT

Objective In this study, electroacupuncture (EA) was used to analyze the expression changes of related proteins in neuroglobin (NGB), PI3K/AKT and apoptotic pathways in the temporal cortex of bilirubin encephalopathy (BE) rats, so as to investigate the therapeutic effect of EA on BE and the relevant mechanism of NGB in this process. Totally 39 seven-day-old SD rats were divided into Sham, BE model and BE+EA groups. The neonatal BE model was established by injecting bilirubin solution (10 μg UCB/g Weight) into the cerebellomedullary cistern, Sham group was injected with the same amount of normal saline. BE rats were treated with EA at Baihui (GV20) and Quchi (LI11) acupoints with the frequency of 2/15 Hz for 15 min. Treatment was performed 12 h before modeling, followed by treatment every 12 h, in a total of three times. HE, Nissl staining and electron microscopy (TEM) were used to observe the pathological and ultrastructural changes of nerve cells in each group. Results showed that EA treatment reduced the damage of cortical neurons of BE rats and increase the number of Nissl bodies. TEM confirmed that EA treatment could alleviate the degree of mitochondria edema. Immunofluorescence staining was used to detect the expression sites and cell types of NGB. Results showed that NGB was mainly expressed in cortical neurons. Western blotting showed that EA treatment increased the expression of NGB, PI3K (p110 alpha), pAKT (Ser473) (P< 0. 05, P< 0. 05 and P< 0. 01, respectively) and the ratio of apoptosis-related protein Bcl-2/Bax (P < 0. 001), decreased the expression of Cleaved Caspase-3 (P< 0. 05) in the temporal cortex of rats. TUNEL staining showed that EA reduced the number of apoptotic cells (BE group 186. 00±13. 86 vs BE+EA group 78. 67±11. 85, P< 0. 01) . This study confirms that EA can promote the expression of NGB in the temporal cortex of BE rats, then activate the PI3K/AKT pathway to exert its neuroprotective function and inhibit the occurrence of apoptosis. EA may become a potential treatment method for BE.

ABSTRACT

Network Meta-analysis was used to compare the efficacy and safety of Chinese patent medicines in the treatment of unstable angina pectoris. PubMed, Cochrane Library, CNKI, Wanfang, VIP and other databases were retrieved by computers from the establishment of the databases to June 2020. Randomized controlled trials(RCTs) of Chinese patent medicines for the treatment of unstable angina pectoris were collected. Two investigators independently screened out the literatures, and extracted data according to the inclusion and exclusion criteria. The quality of the included RCTs was evaluated according to the bias risk assessment tool recommended by the Cochrane System Reviewer Manual, and the Stata 13.0 software was used for data analysis and mapping. Through screening, 28 eligible studies were finally included, with the sample size of 2 885 cases, involving 8 Chinese patent medicines. The results of the network Meta-analysis showed that in terms of total effective rate for angina symptom improvement, the order was as follows: Shenshao Capsules > Naoxintong Capsules > Ginkgo Ketone Ester Dripping Pills > Compound Danshen Dripping Pills > Ginkgo Leaf Tablets > Shexiang Baoxin Pills > Tongxinluo Capsules > Yindan Xinnaotong Soft Capsules; in terms of total effective rate for ECG curative effect, the order was as follows: Ginkgo Ketone Ester Dripping Pills>Compound Danshen Dripping Pills > Tongxinluo Capsules > Shenshao Capsules > Shexiang Baoxin Pills > Yindan Xinnaotong Soft Capsules; in terms of hypersensitivity-C-reactive protein curative effect, the order was as follows: Tongxinluo Capsules > Shenshao Capsules > Ginkgo Leaf Tablets>Compound Danshen Dropping Pills> Shexiang Baoxin Pills > Naoxintong Capsules > Yindan Xinnaotong Soft Capsules > Ginkgo Ketone Ester Dropping Pills. Chinese patent medicine combined with conventional therapy can improve the clinical efficacy of unstable angina pectoris. Due to the differences in the quantity and quality of the included studies, the order results of Chinese patent medicines need to be further verified.

ABSTRACT

Objective:To evaluate the effect of early screening and multidisciplinary management for elderly patients with dysphagia.Methods:All of the elderly patients who were hospitalized during January 2018 to December 2019, were divided into control group ( n=16 273) and intervention group ( n=18 853) according to the order of inpatient. Patients in control group received routine care, and those in intervention group received early screening and multidisciplinary management. The difference of detection, rehabilitation, indwelling, pneumonia and the professional level of nurses were compared between two groups. Results:The positive rate of intervention group was 14.10% (2 659/18 853), which was higher than 10.81% (1 759/16 273) of control group ( χ2 value was 66.11, P<0.01). The rehabilitation rate was increase from 67.08% (1 180/1 759) to 78.68% (2 092/2 659) ( χ2 value was 17.88, P<0.01) . The rate of indwelling nasogastric tube was decreased from 21.49% (378/1 759) to 19.33% (514/2 659) ( χ2 value was 8.52, P<0.01). The incidence of pneumonia was decreased from 10.18% (179/1 759) to 4.25% (113/2 659) ( χ2 value was 37.27, P<0.01). And dysphagia related knowledge ( t value was 7.549, P<0.01) and skills ( t value was 7.413, P<0.01) of the nurses were improved. Conclusion:Implementation of early screening and hierarchical management based on the form of multidisciplinary cooperation for dysphagia in elderly inpatients can enhance the positive outcome of patient and improve dysphagia related knowledge and skills of nurse.

ABSTRACT

Objective To analyze the prevalence and influencing factors of anxiety and depression among pregnant women in Jianyang City. Methods Convenience sampling method was used to select 322 pregnant women in Jianyang Maternal and Child Health Hospital of Jianyang City. The depression and anxiety of the participants were measured with self-rating anxiety scale(SAS) and self-rating depression scale(SDS),and the degree of social support was measured with social support rating scale (SSRS). Pearson correlation analysis was used to analyze the relationship between anxiety, depression and social support. The chi square ( 2) test and the non-conditional Logistic regression model were used to analyze the influencing factors of anxiety and depression. Results Anxiety rate and depression rate of pregnant women in Jianyang city were 5.3% and 5.6% respectively. There was a negative correlation between anxiety, depression and social support (P<0.05). Absence of prenatal examination (OR=4.554, 95% CI: 1.063-19.510) was a risk factor for anxiety among pregnant women in Jianyang City. Late pregnancy (OR=5.381, 95% CI: 1.422-20.363) and medium degree of social support (OR=4.150, 95% CI: 1.198-14.375) were risk factors for depression among pregnant women in Jianyang City. Junior high school (OR=0.015, 95% CI: 0.001-0.275), high school or technical secondary school (OR=0.004, 95% CI: 0.001-0.128), junior college or above (OR=0.053, 95% CI: 0.003-0.851) were protective factors for depression. Conclusions The prevelance of anxiety and depression in pregnant women cannot be ignored. It is important to carry out mental health intervention according to the above factors.
