ObjectiveTo explore the relationship between hand grip strength and depression and the moderating role of monthly household income level between grip strength and depression of community-dwelling female patients with type 2 diabetes.MethodsFrom March to June 2021, 3 communities in Chengdu were selected by convenience sampling method, and elderly female patients with type 2 diabetes were randomly selected from these communities. The patients were investigated through a self-made demographic and disease-related questionnaire and the Geriatric Depression Scale-15, and their grip strength was measured by a grip meter. The Process V3.3 plugin in SPSS 25.0 software was used to test the moderation effect.ResultsA total of 389 elderly female patients with type 2 diabetes were enrolled in this study. Spearman correlation analyses indicated that the grip strength was negatively correlated with the depression score (rs=−0.125, P=0.014), and positively correlated with the monthly household income level (rs=0.157, P=0.002); the depression score was negatively correlated with the monthly household income level (rs=−0.147, P=0.004). The results of the moderating effect showed that grip strength and monthly household income level could independently affect the patients’ depression scores [unstandardized partial regression coefficient (b)=−0.254, P=0.002; b=−1.552, P=0.009], and the interaction item of grip strength and monthly household income level was statistically significant for depression scores (b=0.065, P=0.031).ConclusionThe hand grip strength of community-dwelling elderly female patients with type 2 diabetes can negatively predict the level of depression, and the monthly household income level has a moderating effect between grip strength and depression.
ObjectiveTo explore the feasibility of decompression without gastric tube after minimally invasive esophageal cancer surgery.MethodsSeventy-two patients who underwent minimally invasive esophageal cancer resection at the Department of Thoracic Surgery, The Second Affiliated Hospital of Harbin Medical University from 2016 to 2018 were selected as a trial group including 68 males and 4 females with an average age of 58.5±7.9 years, who did not use gastric tube for gastrointestinal decompression after surgery. Seventy patients who underwent the same operation from 2013 to 2015 were selected as the control group, including 68 males and 2 females, with an average age of 59.1±6.9 years, who were indwelled with gastric tube for decompression after surgery. We observed and compared the intraoperative and postoperative indicators and complications of the two groups.ResultsThere were no significant differences between the two groups in operation time, intraoperative blood loss, postoperative level of serum albumin, postoperative nasal jejunal nutrition, whether to enter the ICU postoperatively, death within 30 days after surgery, anastomotic leakage, lung infection, vomiting, bloating or hoarseness (P>0.05). No gastroparesis occurred in either group. Compared with the control group, the recovery time of the bowel sounds and the first exhaust time after the indwelling in the trial group were significantly shorter, and the total hospitalization cost, the incidence of nausea, sore throat, cough, foreign body sensation and sputum difficulty were significantly lower (P<0.05).ConclusionIt is feasible to remove the gastric tube for gastrointestinal decompression after minimally invasive esophageal cancer surgery, which will not increase the incidence of postoperative complications, instead, accelerate the postoperative recovery of patients.
ObjectivesTo systematically review the teaching efficacy of cardiac ultrasound simulation.MethodsCNKI, VIP, PubMed, EMbase and The Cochrane Library databases were electronically searched to collect randomized controlled trials (RCTs) on cardiac ultrasound simulation from inception to March 7th, 2020. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 7 RCTs involving 300 trainees were included. The results of meta-analysis showed that: compared with traditional teaching method, trainees who received cardiac ultrasound simulation obtained higher cardiac ultrasonic structure image recognition score (SMD=1.38, 95%CI 0.81 to 1.94, P<0.000 01), higher ultrasonic image quality score (SMD=2.08, 95%CI 1.71 to 2.44, P<0.000 01), and shorter time required to obtain the correct ultrasound image (SMD=−1.19, 95%CI −1.55 to −0.83, P<0.000 01).ConclusionsThe current evidence shows that trainees who received cardiac ultrasound simulation have superior teaching effect immediately after the training compared with those who received traditional teaching method. However, further high-quality researches are needed to confirm whether there is a difference between the two training methods in long-term teaching effect.
Objective To explore the influencing factors of sleep quality of the elderly in Chengdu community and put forward corresponding nursing strategies. Methods The elderly in four communities in Chengdu were selected by convenient sampling method from January to June 2021. The elderly in the community were investigated and analyzed by general information questionnaire, Interpersonal Relationship Integrative Diagnostic Scale (IRIDS) and Pittsburgh Sleep Quality Index (PSQI). Multiple linear stepwise regression was used to analyze the factors affecting the sleep quality of the elderly. Results A total of 232 elderly were investigated and 211 were finally included. The total score of PSQI in the elderly was positively correlated with the score of interpersonal conversation disturbance (r=0.297, P<0.05) and the score of treating people disturbance (r=0.208, P<0.05). The results of multiple linear stepwise regression analysis showed that physical exercise, monthly amount of money, education and four dimensions of interpersonal troubles were the main influencing factors of sleep quality in the elderly. Conclusions The community elderly in this study had better sleep quality. Physical exercise, monthly amount of money, education and four dimensions of interpersonal troubles were all important factors affecting the sleep quality of the elderly. Community nursing staff should pay more attention to the sleep quality of the elderly, put forward measures to improve the related factors leading to sleep disorders, encourage the elderly to take physical exercise. They should also provide psychological counseling and interpersonal communication skills for the elderly with interpersonal troubles and help expand the communication platform to improve sleep quality of the elderly in the community.
ObjectiveTo investigate the effect of miR-190a-5p on the polarization of bone-marrow-derived macrophage (BMDM) induced by lipopolysaccharides to M1- and M2-types.MethodsBMDM (M1-type) induced by bacterial lipopolysaccharide was a M1 group. The macrophage M1-type interfered with negative control miRNA mimics was a NC group. miR-190a-5p mimics interfered with the M1-type of macrophages in the miR-190a-5p group. Morphological changes of macrophages were observed under a microscope, and the proportion of M2-type macrophages (CD206+, F4/80) was detected by flow cytometry. The mRNA expression levels of argininase-1 (Arg1), inducible nitric oxide synthase (iNOS), tumor necrosis factor-α (TNF-α), target gene C/EBPα and PU.1 were detected by fluorescence quantitative PCR to verify whether C/EBPα and PU.1 were potential target genes of miR-190a-5p. The expression of pathway proteins C/EBPα and PU.1 were detected by Western blotting.ResultsAfter miR-190a-5p mimics interfered with macrophage M1-type, the antenna of macrophages elongated and showed long cord M2-type cell morphological characteristics. miR-190a-5p mimics interfered with M1-type macrophages for 24 h, and the percentage of M2-type macrophages increased significantly (P<0.05). Effects of miR-190a-5p simulator on mRNA expression levels of M1-type macrophages included: the expression of iNOS and TNF-α was significantly decreased (P<0.05), the expression of Arg1 marked by M2 macrophages was significantly increased (P<0.05), and the mRNA expression levels of target genes C/EBPα and PU.1 were significantly decreased (P<0.05). Western blotting results showed that the overexpression of miR-190a-5p significantly inhibited the protein expressions of C/EBPα and PU.1, while the miR-190a-5p inhibitor increased the expressions of both proteins.ConclusionmiR-190a-5p can promote the polarization of BMDM from M1-type to M2-type.
Objective To explore the risk factors of premature infants death. Methods The medical records of hospitalized premature infants admitted to West China Second University Hospital of Sichuan University between January 2015 and December 2022 were collected. Premature infants were divided into the death group and the non-death group (control group) based on discharge diagnosis of death. Parturient and premature infants related information were collected, and the disease classification and diagnosis of premature infants were analyzed. Results A total of 13 739 premature infants were included, with 53 deaths and a mortality rate of 3.85‰ (53/13 739). The ages of death were 1-49 days, and the median age of death was (9.68±9.35) days. According to the matching method, 212 premature infants were ultimately included. Among them, there were 53 premature infants in the death group and 159 premature infants in the control group. Compared with the control group, premature infants in the death group had lower gestational age, birth weight, lower 1-minute Apgar scores, lower 5-minute Apgar scores and shorter hospital stay (P<0.05), and received more delivery interventions (P<0.05). There was no statistically significant difference in other indicators between the two groups of premature infants (P>0.05). A total of 212 parturient were included. Among them, there were 53 parturients in the death group and 159 parturients in the control group. The use rate of prenatal corticosteroids in the control group was higher than that in the death group (55.35% vs. 54.72%). There was no statistically significant difference in other related factors between the two groups of parturient (P>0.05). The results of logistic regression analysis showed that longer hospital stay [odds ratio (OR)=0.891, 95% confidence interval (CI) (0.842, 0.943), P<0.001], prenatal use of corticosteroids [OR=0.255, 95%CI (0.104, 0.628), P=0.003] reduced the risk of premature infant death. However, tracheal intubation [OR=10.738, 95%CI (2.893, 39.833), P<0.001] increased the risk of premature infant death. Conclusions Clinicians should pay attention to prenatal examination of newborns and pay attention to evaluation of newborn status. Obstetricians and neonatologists should make joint plans for women with high risk factors for preterm delivery. During the hospitalization, after the diagnosis is clear, standardized treatment should be carried out in strict accordance with the guidelines for systemic diseases and expert consensus.
Objective To predict the patients who can benefit from local surgery for bone-only metastatic breast cancer (bMBC). Methods Patients newly diagnosed with bMBC between 2010 and 2019 in SEER database were randomly divided into a training set and a validation set at a ratio of 7∶3. The Cox proportional hazards model was used to analyze the independent prognostic factors of overall survival in the training set, and the variables were screened and the prognostic prediction model was constructed. The concordance index (C-index), time-dependent clinical receiver operating characteristic curve and area under the curve (AUC), calibration curve and decision curve analysis (DCA) were used to evaluate the discrimination, calibration and clinical applicability of the model in the training set and validation set, respectively. The model was used to calculate the patient risk score and classify the patients into low-, medium- and high-risk groups. Survival analysis was used to compare the survival difference between surgical and non-surgical patients in different risk groups. Results A total of 2057 patients were enrolled with a median age of 45 years (interquartile range 47-62 years) and a median follow-up of 32 months (interquartile range 16-53 months). Totally 865 patients (42.1%) died. Multivariate Cox proportional hazards model analysis showed that the overall survival of patients with surgery was better than that of patients without surgery [hazard ratio=0.51, 95% confidence interval (0.43, 0.60), P<0.001]. Chemotherapy, marital status, molecular subtype, age, pathological type and histological grade were independent prognostic factors for overall survival (P<0.05), and a prognostic prediction model was constructed based on the independent prognostic factors. The C-index was 0.702 in the training set and 0.703 in the validation set. The 1-, 3-, and 5-year AUCs of the training set and validation set were 0.734, 0.727, 0.731 and 0.755, 0.737, 0.708, respectively. The calibration curve showed that the predicted survival rates of 1, 3, and 5 years in the training set and the validation set were highly consistent with the actual survival rates. DCA showed that the prediction model had certain clinical applicability in the training set and the validation set. Patients were divided into low-, medium- and high-risk subgroups according to their risk scores. The results of log-rank test showed that local surgery improved overall survival in the low-risk group (training set: P=0.013; validation set: P=0.024), but local surgery did not improve overall survival in the medium-risk group (training set: P=0.45; validation set: P=0.77) or high-risk group (training set: P=0.56; validation set: P=0.94). Conclusions Local surgery can improve the overall survival of some patients with newly diagnosed bMBC. The prognostic stratification model based on clinicopathological features can evaluate the benefit of local surgery in patients with newly diagnosed bMBC.
Objective To identify pancreatic duct-derived stem cells （PDSCs） from the pancreatic duct of rats, and culture in three-dimension cell culture system or two-dimension cell culture, with characterization on their morphology and phenotype. Methods Adult male Wistar rats underwent perfusion with collagenaseⅤvia the pancreatic duct, the pancreas was surgically procured, digested, followed by discontinued density gradient centrifuge to isolate islets from acinar and ductal tissue. The acinar and ductal tissues were cultivated in serum-containing medium in the three-dimension or two-dimension cell culture seperatedly to obtain adherent cells, as PDSCs, which were expanded by consecutive passages. The cell junction, cell cycle, and cell apoptosis rate between the two-dimension and three-dimision cell culture were compared by means of microscope and flow cytometry. Results PDSCs of rats showed direct adherence culture in three-dimension and two-dimision cell culture systerm. PDSCs grew in many layers in three-dimension cell culture system on 2 days after culture, and possessed capacity of high proliferation on 7 days. Cells were adherent to the bottom of flask on 5 days after culture in two-dimision cell culture. Cell junctions were more obvious in three-dimension cell culture system. Compared with the two-dimision cell culture, the cells of G1 phase increased〔（56.46±1.17） % vs.（37.33±1.21）%〕, and the cells of G2 phase decreased〔（14.62±0.15） % vs. （32.40±1.21）%〕in three-dimension cell culture system （P＜0.01）. The early period apoptosis rate was lower in three-dimension cells culture system than that in two-dimision cell culture 〔（1.48±0.39）% vs. （5.24±1.33）%, P＜0.05〕. The late period apoptosis rate was no statistically significant difference between the three-dimension and two-dimension cell culture （P＞0.05）. Conclusions PDSCs of rats could be obtained in the three-dimension cell culture system. There is cell junction in three-dimension culture mode, which shows a significant enhancement on intercellular interaction, and the biological characters are different between the three-dimension and two-dimension cell culture.
Objective To explore the level and influencing factors of caregiver burden of children of the patients with breast cancer. Methods We collected 153 patients with breast cancers and their children in Suining Central Hospital from January 2014 to July 2015 . Their children were investigated with Zarit Burden Interview and Caregiver Strain Idex. Results The ZBI score of the patients' children was in the middle level with a total score of 38.09±14.41. The differences in ZBI scores of the influencing factors including different daily sleep time, education, family income and cancer stages of patients were significant (P<0.05). The caregiver strain showed that social pressure was the largest, economy pressure was in the middle, and the psychological pressure was the minimal. Conclusions The children caregivers of the patients with breast cancer suffer from middle level of burden. Doctors should provide targeted intervention to ease the caregiver burden and improve the life quality of the patients' family.
