ABSTRACT
Objective:To explore the application value of computed tomography (CT) plain scan and dynamic enhanced scan in the diagnosis of solitary pulmonary nodules.Methods:The clinical data of 120 patients with solitary pulmonary nodules detected by physical examination in Baoding First Central Hospital from January 2018 to December 2020 were retrospectively reviewed. All patients were confirmed by surgery and pathology, including 77 benign lesions and 43 malignant lesions; All patients underwent CT plain scan and dynamic enhanced scan before operation. The accuracy of the two examination methods in the diagnosis of benign and malignant lesions of solitary pulmonary nodules was analyzed and compared. The detection rate of CT dynamic enhanced scan imaging characteristics (vacuole sign, ground glass sign, spinous sign, lobulation sign, hair prick sign, blood vessel cluster, pleural depression) of benign and malignant lesions of solitary pulmonary nodules was compared, and the diagnostic value of CT plain scan and dynamic enhanced scan in the differential diagnosis of benign and malignant solitary pulmonary nodules was evaluated based on the results of surgical pathological diagnosis. The manifestations and characteristic curves of CT dynamic enhanced scan of solitary pulmonary nodules was analyzed.Results:The diagnostic accuracy of CT dynamic enhanced scan for solitary pulmonary nodules was 80.00% (96/120), which was higher than that of CT plain scan (63.33%) (76/120) ( P<0.05). The sensitivity, specificity, and negative predictive value of CT dynamic enhanced scan for the diagnosis of benign and malignant lesions of solitary pulmonary nodules were higher than those of CT plain scan (all P<0.05). Among the imaging characteristics of CT dynamic enhanced scans of malignant lesions, the ground glass sign, spinous process sign, lobulation sign, spiculation sign, vascular clustering and pleural indentation were detected more frequently than those of benign lesions (all P<0.05). Benign lesions usually showed homogeneous enhancement, and a few showed heterogeneous enhancement; Malignant nodules often showed uneven enhancement, and a few had even enhancement. The time density curves of dynamic enhanced CT values in the regions of interest of benign and malignant solitary pulmonary nodules were different. Conclusions:The value of dynamic enhanced CT scan in the differential diagnosis of benign and malignant lesions of solitary pulmonary nodules is higher than that of CT plain scan, and the imaging features are obvious, with higher sensitivity and specificity, which is worthy of application.

ABSTRACT
Purpose@#The role of vacuolar protein sorting 34 (Vps34), an indispensable protein required for cell vesicular trafficking, in the biological behavior of hepatocellular carcinoma (HCC) has yet to be studied. @*Materials and Methods@#In the present study, the expression of Vps34 in HCC and the effect of Vps34 on HCC cell invasion was detected both in vivo and in vitro. Furthermore, by modulating the RILP and Rab11, which regulate juxtanuclear lysosome aggregation and recycling endosome respectively, the underlying mechanism was investigated. @*Results@#Vps34 was significantly decreased in HCC and negatively correlated with the HCC invasiveness both in vivo and in vitro. Moreover, Vps34 could promote lysosomal juxtanuclear accumulation, reduce the invasive ability of HCC cells via the Rab7-RILP pathway. In addition, the deficiency of Vps34 in HCC cells affected the endosome-lysosome system, resulting in enhanced Rab11 mediated endocytic recycling of cell surface receptor and increased invasion of HCC cells. @*Conclusion@#Our study reveals that Vps34 acts as an invasion suppressor in HCC cells, and more importantly, the endosome-lysosome trafficking regulated by Vps34 has the potential to become a target pathway in HCC treatment.
ABSTRACT
A strong animal survival instinct is to approach objects and situations that are of benefit and to avoid risk. In humans, a large proportion of mental disorders are accompanied by impairments in risk avoidance. One of the most important genes involved in mental disorders is disrupted-in-schizophrenia-1 (DISC1), and animal models in which this gene has some level of dysfunction show emotion-related impairments. However, it is not known whether DISC1 mouse models have an impairment in avoiding potential risks. In the present study, we used DISC1-N terminal truncation (DISC1-N
ABSTRACT
Zinc is one of the essential trace elements for human. It is essential for human health. In recent decades, the distribution and transport of zinc in human body have gradually become more evident. The immunomodulatory effects of zinc on the immune system have also been elucidated. Zinc is involved in regulating the cellular signaling pathways of immune cells and affecting the development of immune organs, the physiological state and function of immune cells and the secretion of cytokines. It is an indispensable element in the immune system and plays an important role in maintaining the integrity and stability of the immune system. This article briefly introduced the distribution and transportation of zinc in the human body, with the emphasis on the relationship between zinc and the development and function of immune cells.
ABSTRACT
Human coronavirus OC43 (HCoV-OC43) and severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) belong to the β-coronavirus genus. Since the discovery in 1967, HCoV-OC43 has been continuously circulating in human population and has become one of the common seasonal respiratory viruses. SARS-CoV-2, which has a higher morbidity and fatality rate, appeared at the end of 2019, followed by the emergence of a variety of variants, and the transmission and infection capacity of SARS-CoV-2 has been enhanced. HCoV-OC43 may be similar to SARS-CoV-2 in terms of genomic structure and function, species evolution, epidemic characteristics and clinical manifestations. In this review, the epidemiology, genomics, phylogenetic evolution and other aspects of HCoV-OC43 and SARS-CoV-2 were analyzed. Such an analysis would be helpful to understand the association and differences between the two viruses, and provide reference for understanding the potential threats of HCoV-OC43.
ABSTRACT
Objective:To explore the threshold and diagnostic value of Chinese version of the Chelsea Physical Function Assessment Tool (CPAx-Chi) for ICU acquired weakness(ICU-AW).Methods:To learn the details and precautions of the CPAx-Chi scale, and then two researchers used the CPAx-Chi scale and MRC-Score scale to independently evaluate 200 patients who come from a comprehensive ICU in a top first-class hospital in Gansu Province simultaneously. The best cut-off point and value of the CPAx-Chi scale in the diagnosis of ICU-AW were determined by calculating the Receiver Operating Characteristic (ROC) curve, the Youden index(YI) and the consistency test that are all based on the MRC-Score≤48.Results:The ROC Area Under Curve(AUC) of the CPAx-Chi scale diagnosis ICU-AW which based on the MRC-Score≤48 were as follows: ROC AUC of group A was 0.899 (95% CI 0.862-1.025); ROC AUC of group B was 0.874 (95% CI 0.824-0.925). When the best cut-off point of CPAx-Chi scale for diagnosis ICU-AW was 31.5, the maximum YI=0.643, the sensitivity was 87%, and the specificity was 77% in group A; and the maximum YI= 0.62, the sensitivity was 75%, and the specificity was 87% in group B. Meanwhile, when the best cut-off point of CPAx-Chi scale for diagnosis ICU-AW was 30.5, the maximum YI=0.62, the sensitivity was 79%, and the specificity was 83% in group B. Taking the CPAx -Chi≤31 as the best cut-off point, the score differences in ICU-AW group and the non-ICU-AW group were not detected, A group ( F value was 4.53, P=0.035) or B group ( F value was 6.51, P=0.011). The consistency of CPAx -Chi≤31 and MRC-Score≤48 in the diagnosis of ICU-AW was high, and the Kappa=0.845 ( P=0.02) in the group A; the Kappa=0.839( P=0.04) in the group B, and the group differences were detected. Conclusions:CPAx-Chi≤31 is the best cut-off point for diagnosing ICU-AW, and has good sensitivity and specificity. CPAx-Chi scale can be popularized and applied in the critical care medicine in China.
ABSTRACT
Objective:To study the effects of broad-spectrum antibiotics and induced antibiotic-resistant bacteria on the efficacy of 5-fluorouracil (5-FU) chemotherapy for mice with colon cancer and to investigate the underlying mechanisms associated with anti-tumor immune responses.Methods:BALB/c mice were subcutaneously injected with CT26 colon cancer cells and randomized into four groups: tumor-bearing control group, antibiotic group treated with ampicillin, streptomycin and colistin, 5-FU group and anitibiotic+ 5-FU group. Tumor volumes and body weights were measured and recorded. Seven days after the last 5-FU treatment, the percentages of splenic immune cell subpopulations and proliferated CD8 + T cells after co-culturing with CT26 were analyzed by flow cytometry. Gut microbiota composition was detected by 16S rRNA sequencing and the bacteria in mesenteric lymph nodes (mLN) were isolated and cultured. Bone marrow-derive macrophages were stimulated with identified bacteria and the expression of M1 and M2 polarization markers were assessed by quantitative PCR. The proliferation of CD8 + T cells co-cultured with bacteria-treated macrophages was analyzed by flow cytometry. In addition, tumor-bearing mice were treated with 5-FU and oral gavage of bacteria isolated from antibiotic+ 5-FU group or PBS. Tumor volumes, gut microbiota composition and the percentages of proliferated CD8 + T cells co-cultured with CT26 were assessed. Results:Tumor volumes were larger and body weights were lower in the antibiotic+ 5-FU group than in the 5-FU group. The percentages of CD4 + T cells, CD8 + T cells and neutrophils did not varied significantly after using antibiotics, however, the percentage of monocytes was increased in the antibiotic group. The percentage of proliferated tumor-specific CD8 + T cells in the antibiotic+ 5-FU group was decreased compared with that in the 5-FU group. Compared with the control group and 5-FU group, antibiotic usage was associated with the changes in gut microbiota composition with decreased α diversity indexes. Escherichia coli, Klebsiella pneumonia, and Proteus mirabilis were isolated from mLNs of the antibiotic group, 5-FU group and antibiotic+ 5-FU group, respectively. Bone marrow-derived macrophages stimulated with Proteus mirabilis expressed arginase at a high level, which was a M2 polarization marker of macrophage, and associated with the decreased percentage of proliferated CD8 + T cells after co-culturing. Bacteria of the genus Proteus were enriched in the gut microbiota of 5-FU-treated tumor-bearing mice with the oral gavage of Proteus mirabilis. Although no significant inhibitory effect on tumor growth was observed, the oral gavage of Proteus mirabilis was associated with the decreased percentage of proliferated tumor-specific CD8 + T cells in vitro. Conclusions:Broad-spectrum antibiotics inhibited the efficacy of chemotherapy and the proliferation of tumor-specific CD8 + T cells, in which antibiotic-resistant bacteria might be involved.
ABSTRACT
Objective:To evaluate the effect of lower limb neuromuscular electrical stimulation (NMES) on mechanical ventilation patients in intensive care unit (ICU).Methods:Databases including the Cochrane Library, PubMed, Web of Science, Embase, SinoMed, CNKI, VIP and Wanfang database were searched from inception to May 2021. Randomized controlled trails (RCT) about the influence of NMES of lower limbs in patients with mechanical ventilation in ICU were collected. Routine rehabilitation measures were implemented in the control group, while the combination of routine rehabilitation and NMES on the lower limbs was implemented in the observation group. The literature screening, data extracting, and bias risk assessment of included studies were conducted independently by two reviewers. RevMan 5.3 software was used to perform Meta-analysis. Funnel plot was used to test publication bias.Results:A total of 8 RCT were eventually enrolled. The literature quality evaluation results showed that 1 study was grade A and 7 studies were grade B, suggesting that the quality of the included literature was relatively high. The Meta-analysis results showed that NMES in the lower extremities could effectively shorten the duration of mechanical ventilation in ICU patients [standardized mean difference ( SMD) = -0.51, 95% confidence interval (95% CI) was -0.72 to -0.31, P < 0.000 01], increase the maximum inspiratory pressure [MIP; mean difference ( MD) = 14.19, 95% CI was 9.30 to 19.09, P < 0.000 01], and improve the functional status of critically ill patients [functional status score for ICU (FSS-ICU); MD = 10.44, 95% CI was 3.12 to 17.77, P = 0.005] with statistically significances. However, there were no significant advantages in increasing the Medical Research Council (MRC) score ( MD = 2.13, 95% CI was -1.38 to 5.63, P = 0.23), reducing ICU mortality [relative risk ( RR) = 0.80, 95% CI was 0.51 to 1.24, P = 0.31], shortening length of ICU stay ( MD = -0.54, 95% CI was -3.67 to 2.59, P = 0.74), and the combined effect was not statistically significant. Funnel plot based on the duration of mechanical ventilation showed that the distribution of included articles was basically symmetrical, and no publication bias was detected. Conclusions:NMES of the lower limbs can not only shorten the ventilation duration effectively, but also improve the MIP and functional status of mechanically ventilated patients in ICU. However, it has no significant effect on the MRC score, ICU mortality and length of ICU stay of patients with mechanical ventilation. In the future, high-quality, large sample size and multi-center RCT are needed to verify the effects of NMES.
ABSTRACT
Objective:To evaluate the effect of early mobilization on mortality in intensive care unit (ICU) patients with mechanical ventilation after discharge by Meta-analysis.Methods:Databases including SinoMed, China National Knowledge Infrastructure (CNKI), Wanfang data, PubMed, the Cochrane Library, Web of Science, and Embase were searched from inception to September 17th, 2020, to collect randomized controlled trials (RCT) about early mobilization on mortality of patients with mechanical ventilation in ICU after discharge, the references included in the literature were traced. The control group was given routine care, the experimental group was given early mobilization on the basis of the control group, including passive or active mobilization on the bed, sitting on the bed, standing by the bed, transferring to the bedside chair and assisting walking. The literature screening, data extracting, and the bias risk assessment of included studies were conducted independently by two reviewers. Stata 12.0 software was then used to perform Meta-analysis. Funnel plot was used to test publication bias.Results:A total of 10 RCT studies involving 1 323 patients were included, with 660 patients in the control group and 663 patients in the experimental group. The results of literature quality evaluation showed that 7 studies were grade A and 3 studies were grade B, indicating that the overall quality of included literatures was high. The Meta-analysis results showed that early mobilization did not increase the mortality of patients with mechanical ventilation in ICU after discharge [odds ratio ( OR) = 0.92, 95% confidence interval (95% CI) was 0.75-1.13, P = 0.449]. Subgroup analysis results showed that early mobilization had a tendency to reduce the mortality of ICU patients with mechanical ventilation at 3, 6 and 12 months after discharge, but the difference was not statistically significant (3-month mortality: OR = 1.02, 95% CI was 0.74-1.40, P = 0.927; 6-month mortality: OR = 0.95, 95% CI was 0.70-1.27, P = 0.712; 12-month mortality: OR = 0.60, 95% CI was 0.33-1.10, P = 0.101). Funnel plot showed that the distribution of included literatures was not completely symmetrical, suggesting that publication bias might exist. Conclusions:Early mobilization does not increase the mortality of ICU patients with mechanical ventilation after discharge. Although it tends to have a favorable outcome in reducing mortality, and has a trend to reduce the mortality. However, due to the small number of included literatures, small sample size and differences in the specific implementation of early mobilization among various studies, a large number of high-quality RCT studies are still needed for further verification.

Objective:To investigate the current status of intensive care unit-acquired weakness (ICU-AW) assessment, analyze the assessment barriers, and to provide reference to improve ICU-AW assessment.Methods:A convenient sampling cross-sectional survey was conducted. First, an interview outline which based on related domestic and international literatures and combining with the research purpose of this study were designed. Thirteen medical personnel (8 ICU nurses, 3 ICU doctors, 1 respiratory therapist and 1 physiotherapist) who worked in the intensive care unit (ICU) of the First Hospital of Lanzhou University were enrolled with convenience sampling method to interview. Second, the topics were comprehensively analyzed and extracted, and then a questionnaire was constructed, and the reliability and validity was assessed. Finally, the questionnaire survey including the general situation of ICU medical staffs, the current practices of ICU-AW and influencing factors was implemented in China.Results:The retest reliability was 0.92 and expert validity was 0.96 of the questionnaire. There were 3 563 respondents in 31 provinces, municipalities and autonomous regions which eliminated 357 unqualified questionnaires, including 173 respondents from neonatal or pediatric ICU, 89 respondents whose working time was less than 6 months, and 95 invalid respondents, and then there were finally 3 206 valid questionnaires and the response rate were 90.0%. Those 3 206 respondents included 616 doctors (19.2%), 2 371 nurses (74.0%), 129 respiratory therapists (4.0%), 51 physiotherapist (1.6%) and 39 dietitians (1.2%). The mean age was (30.7±6.3) years old. Most of them had bachelor's degree (65.9%), master and above was 14.1%. Associate senior physician and above was 8.0%; ICU working time was (5.94±4.50) years. In clinical practice, only 26.5% of the ICU medical staffs confirmed that they had treated or taken care for ICU-AW patients; 52.9% of medical staffs evaluated ICU-AW only based on clinical experience, and only 12.3% used ICU-AW assessment tools. The majority of respondents believed that ICU-AW knowledge training should be performed (81.8%), ICU-AW assessment should be as important as other complications (pressure sore, infected ventilator associated pneumonia, etc., 75.1%), and ICU-AW assessment should be part of daily treatment and care activities (61.2%). However, only 10.2% of respondents had received ICU-AW related knowledge training, and 42.7% respondents believed that their ICU-AW related knowledge could not meet clinical needs. Only 18.7% respondents would actively assess whether patients suffered from ICU-AW or not, and 42.3% respondents thought that ICU-AW should be assessed every day, and the assessment tools were also inconsistent. There were 44.0% respondents considered the Medical Research Council Muscle score (MRC-score) scale was the optimal tool for diagnosing ICU-AW, the following were neuro-electrophysiological examination (17.2%) and manual muscle strength (MMT, 11.1%). The main cause of the ICU-AW assessment barriers was the lack of ICU-AW related knowledge (88.1%), and the following were lack of ICU-AW assessment guidelines (76.5%), patients' cognitive impairment or limited understanding ability (84.6%), unable to cooperate with the assessment due to critical illness (83.0%), and inadequate attention to ICU-AW assessment by the department (77.5%).Conclusion:The current status of ICU-AW assessment were unsatisfying in China, and the main barriers were lack of skills and knowledge.
ABSTRACT
Objective:To investigate the cognitive impairment after intensive care unit (ICU) discharge and provide theoretical basis for prevention and intervention.Methods:Studies about cognitive impairment after ICU discharge were retrieved in PubMed, Embase, Cochrane Library, Web of Science, Wanfang data, CNKI and SinoMed from their foundation to December 2019. The literature screening and data extraction were performed by two researchers independently, and the quality of different types of researches was evaluated using Cochrane Handbook 5.1.0, Newcastle-Ottawa scale (NOS) and agency for healthcare research and quality criteria (AHRQ). The Meta-analysis was performed by Stata 13.0 software. Sensitivity analysis was used to determine the reliability of the combined effect values. Funnel plot and Egger test were used to analyze publication bias. The non-parametric clipping was used to evaluate the impact of publication bias on the results.Results:A total of 35 studies were enrolled, including 27 prospective cohort studies, 4 retrospective cohort studies, 2 randomized controlled trial (RCT) studies, 1 case-control study, and 1 cross-sectional study. Three literatures were published in Chinese and 32 were in English, which covered 13 countries, and a total of 102 504 ICU survivors were followed up successfully. Literature quality evaluation results showed that the NOS scores of 31 cohort studies were between 6 and 9, of which the case-control study scored 9. The quality grade of 2 RCT studies were both B. According to the AHRQ criteria, 1 cross-sectional study's design was scientifically rigorous and of high quality. Thirty-five studies reported that the overall incidence of cognitive impairment after ICU discharge ranged from 2.47% to 66.07%. For the multiple follow-ups studies, the first survey data was selected for Meta-analysis, and the results showed that the pooled incidence was 38.44% [95% confidence interval (95% CI) was 29.32-47.55]. Each study was removed for sensitivity analysis and the pooled results did not change much, which indicated that the results were reliable. The sub-group analysis was performed on different evaluation methods for cognitive impairment after ICU discharge, different types of ICU patients, and different follow-up time. The results showed that the pooled incidence of studies using neuropsychological test to evaluate cognitive impairment after ICU discharge was 31.42% (95% CI was 21.82-41.02), the pooled incidence of studies using questionnaires or scales was 38.75% (95% CI was 29.54-47.96), and the difference between the two groups was statistically significant ( P < 0.01). The pooled incidence of cognitive impairment after ICU discharge in general ICU patients was 43.42% (95% CI was 30.88-55.95), acute respiratory distress syndrome (ARDS) patients' pooled incidence was 34.40% (95% CI was 23.02-45.79), and the pooled incidence of elderly ICU patients was 12.93% (95% CI was 8.48-17.37), the difference among the three groups was statistically significant ( P < 0.01). The incidences of cognitive impairment < 1 year, 1 to 4 years, ≥ 5 years after ICU discharge were 43.30% (95% CI was 29.47-57.13), 34.21% (95% CI was 26.70-41.72), and 20.22% (95% CI was 4.89-35.55), respectively, and the differences among the three groups were statistically significant ( P < 0.01). The funnel plot showed that the distribution of all studies was asymmetric, and the Egger test result also suggested that there might be publication bias ( P < 0.05). The non-parametric clipping was used to estimate the impact of publication bias on the results, and the result showed that the difference in the incidence of cognitive impairment after ICU discharge before and after non-parametric clipping was large, suggesting that publication bias might influence the stability of the research results. Conclusions:The incidence of cognitive impairment after ICU discharge is relatively high and persistent for a long time, but diagnostic criteria of cognitive impairment and follow-up time are quite different. It is necessary to develop consistent evaluation criteria and rigorous designed research in the further.
ABSTRACT
Objective:To evaluate the effect of preventing and treatment of pharmaceuticals on intensive care unit-acquired weakness (ICU-AW) by systematic review.Methods:The randomized controlled trials (RCTs) concerning pharmaceutical prevention and treatment about ICU-AW in SinoMed, CNKI, Wanfang data, PubMed, Cochrane Library, Web of Science, EMbase, and other sources were searched from their foundation to May 30th, 2019. The patients in the intervention group were treated with drugs to prevent or treat ICU-AW; and those in control group were treated with other rehabilitation methods. Data searching, extracting and quality evaluation were assessed by two reviewers independently. Stata 12.0 software was then used for Meta-analysis. Only descriptive analysis was conducted when only one study was enrolled.Results:A total of 11 RCTs were enrolled with 1 865 patients in the intervention group and 1 894 in the control group. The results of quality evaluation showed that 4 studies were A-level and 7 studies were B-level, indicating that the overall quality of the enrolled literature was high. Meta-analysis showed that intensive insulin therapy could prevent ICU-AW [relative risk ( RR) = 0.761, 95% confidence interval (95% CI) was 0.662-0.876, P = 0.000], but reduced phenylalanine loss (nmol·100 mL -1·min -1: -3±3 vs. -11±3, P < 0.05) and glutamine intake (nmol·100 mL -1·min -1: -97±22 vs. -51±13, P < 0.05). There was no significant difference in the prevention and treatment of ICU-AW between other drugs (including growth hormone, glutamine, dexmedetomidine, neostigmine, oxandrolone, and intravenous immunoglobulin) and control group. Conclusions:Intensive insulin therapy can prevent ICU-AW, but the risk of hypoglycemia will increase. Other drugs including growth hormone, glutamine, dexmedetomidine, neostigmine, oxandrolone, and intravenous immunoglobulin have no obvious advantages in the prevention and treatment of ICU-AW, so no drug has been recommended to prevent and treat ICU-AW.
ABSTRACT
Objective:To investigate the relationship between gallbladder carcinoma and gallbladder stones, and provide theoretical basis for the prevention and treatment of gallbladder carcinoma.Methods:A case-control study was used to retrospectively analyze the clinical data of 134 patients(study group) with gallbladder stones and gallbladder carcinoma treated in the Xinjiang Uygur Autonomous Region Corps Hospital of Chinese People′s Armed Police Forces from January 2010 to December 2012.Another 134 patients with gallbladder stones were selected as control group, and the clinical characteristics of the two groups were compared.Results:The average age of patients in the study group was (60.5±11.7)years, which was significantly older than that in the control group [(49.6±10.3)years], the difference was statistically significant ( t=7.916, P<0.05). The history of gallbladder stones in the study group and control group were (9.3±4.1)years and (4.6±2.5)years, respectively, and the difference between the two groups was statistically significant( t=11.682, P<0.01). The multiple stones, maximum stone diameter and maximum gallbladder wall thickness in the study group were 75 cases, (2.4±0.6)cm and (0.59±0.16)cm, respectively, which in the control group were 46 cases, (1.3±0.5)cm and (0.87±0.23)cm, respectively, the differences between the two groups were statistically significant(χ 2=3.978, t=6.217, 5.110, all P<0.05). The incidences of cholecystitis and jaundice in the study group were higher than those in the control group, and the differences were statistically significant(all P<0.05). Conclusion:Gallbladder stones are one of the causative factors of gallbladder carcinoma.Early diagnosis of gallbladder carcinoma is difficult.Patients with high-risk gallbladder stones who are old, have a long history of gallbladder stones, multiple stones, large stone diameters, and thick gallbladder walls should actively undergo surgical intervention.
ABSTRACT
Objective:To compare the clinical characteristics of elderly-onset versus non-elderly-onset acute renal infarction(ARI).Methods:Fifty-two patients with ARI diagnosed by contrast-enhanced computed tomography(CECT)or renal arteriography were classified into elderly group(onset age ≥ 65 year, n=17)and non-elderly group(onset age <65 year, n=35). Demographic data, risk factors, initial clinical presentations, laboratory data, diagnosis, treatment and prognosis were analyzed and compared between the two groups.Results:Embolic ARI was more common in elderly group than in the non-elderly group(82.4% or 14/17 vs.45.7% or 16/35, χ2=6.290, P=0.012). Patients complicated with atrial fibrillation(64.7% or 11/17 vs.34.3% or 12/35, χ2=4.290, P=0.038), coronary artery disease(52.9% or 9/17 vs.8.6% or 3/35, P=0.001)and obesity(40.0% or 4/10 vs.8.0% or 2/25, P=0.043)were more and smokers were less( P=0.007)in the elderly group than in non-elderly group.The incidence of lumbar pain( P=0.038)and the platelet count was lower( P=0.016)in elderly group than in non-elderly group.The median duration from hospital presentation to the diagnosis of ARI was shorter in elderly group than in non-elderly group[18 h(2-192) vs.48 h(2-552), Z=2.404, P=0.021]. The CECT scan was the most common diagnostic technique and anticoagulation was the most common therapy in both groups.The median time from the beginning of treatment to disappearance of symptoms were 3 d(range, 1-9)and 11 d(range, 4-50), and the median time of hospital stay were 3 d(range, 1-12)and 13 d(range, 2-64)in the elderly and non-elderly group, respectively.There was no in-hospital mortality in both groups.There was no significant difference in the prognosis between the two groups after a mean follow-up of(39.4±35.8)months( P>0.05). Conclusions:Thromboembolism due to heart disease is the main etiology of ARI in the elderly.Although elderly patients can be diagnosed relatively early, the prognosis of elderly patients is the same as that of non-elderly patients after treatment.Meanwhile, delays in diagnosis and initiating treatment for the elderly with ARI are still common.

Meta-analysis showed that the incidence of deep venous thrombos[RR=0.38, 95%CI(0.24, 0.61), P<0.01], and incidence of pulmonary infection[RR=0.26, 95% CI (0.10, 0.67), P=0.005], incidence of urinary tract infections[RR=0.28, 95%CI(0.10,0.78), P=0.01], incidence of constipation [RR=0.30, 95% CI (0.17,0.56), P=0.0001], The incidence of bloating [RR=0.35, 95%CI(0.13, 0.95), P=0.04], they were lower in the experimental group than in routine care, they were statistically significant. Incidence of incision infection [RR=0.75, 95% CI(0.17, 3.27), P= 0.70], incidence of pressure sores [RR=0.34, 95% CI(0.09, 1.27), P=0.11], incidence of nausea and vomiting [RR=0.81, 95% CI(0.52, 1.25), P=0.34] were not statistically significant; postoperative hospital stay, hospitalization costs, and patient satisfaction were statistically significant.@*Conclusions@#Compared with routine care, the ERAS nursing model can promote the recovery of orthopedic patients during perioperative period, reduce postoperative deep venous thrombosis, constipation, pulmonary infection, urinary tract infection, postoperative hospital stay, hospitalization costs, and patient satisfaction. All have a positive impact, but more multicentre and large sample clinical trials are needed for validation.
ABSTRACT
Keratin (K) is the main component of the epithelial cell mesenchymal cytoskeleton, which protects the integrity of epithelial cells and maintains the function of normal epithelial cells. The expression of keratin affects epidermal proliferation and differentiation, and so as to be used as a marker for proliferation, differentiation and migration of keratinocytes. Middle ear cholesteatoma is one of the common ear diseases. In the middle ear cholesteatoma, keratinocytes over-proliferate and keratin debris accumulates. In this paper, we reviewed the recent studies on middle ear cholesteatoma and explained the possible mechanisms of keratin in the pathogenesis of middle ear cholesteatoma from the aspects of "proliferation" and " bone resorption ". At the same time, the existing problems as well as the prospect of the future research were discussed.
ABSTRACT
Objective@#To investigate the clinical efficacy of percutaneous nephroscopy in the treatment of retroperitioneal abscess after common bile duct exploration.@*Methods@#The retrospective and descriptive study was conducted. The clinical data of 13 patients with retroperitioneal abscess after common bile duct exploration who were admitted to Xinjiang Autonomous Region Hospital of Chinese People′s Armed Forces between January 2004 and December 2018 were collected.There were 5 males and 8 females, aged from 34 to 81 years, with an average age of 57 years. All the 13 patients underwent debridement and drainage for retroperitioneal abscess under percutaneous nephroscope. Observation indicators: (1) surgical and postoperative situations; (2) follow-up. Follow-up was performed using outpatient examination and telephone interview to detect postoperative choledocholithiasis recurrence up to September 2019. Measurement data with skewed distribution were represented as M (range). Count data were described as absolute numbers.@*Results@#(1) Surgical and postoperative situations: all the 13 patients underwent successfully debridement and drainage for retroperitioneal abscess under percutaneous nephroscope, without kidney injury, pancreatic damage, vascular injury or peritoneal damage. There were 11 cases with 1 drainage tube, and 2 cases with 2 drainage tubes. The operation time, volume of intraoperative pus extracted, time to body temperature resuming to normal of 13 patients were 41 minutes (range, 24-77 minutes), 241 mL (range, 110-640 mL), 1.5 days (range, 1.0-4.0 days), respectively. The time to postoperative removal of drainage tube of 13 patients was 42 days(range, 5-94 days), in which the time to postoperative removal of drainage tube at right iliac region was 5 days and 11 days in 2 patients, and at lower back was 23-94 days in 11 patients, respectively. Duration of postoperative hospital stay was 42 days (range, 26-67 days). All the 13 patients had pleural effusion disappeared, and were cured and discharged. (2) Follow-up: 13 patients were followed up for 6-48 months, with a median time of 18 months. No recurrence occurred.@*Conclusion@#The treatment with percutaneous nephroscopy is safe and effective for retroperitioneal abscess after common bile duct exploration.
