Rectal cancer is a common malignant tumor in China, with a high mortality rate ranking fifth. Neoadjuvant therapy for rectal cancer can improve patient prognosis and even achieve pathological complete remission (pCR) in some patients, thereby avoiding complications and functional damage caused by radical surgery. Therefore, how to accurately evaluate pCR before surgery is currently a research hotspot. In recent years, new imaging technologies such as endorectal ultrasound, magnetic resonance imaging (MRI), and positron emission computed tomography (PET-CT) have developed rapidly, and imaging evaluation of pCR after neoadjuvant therapy for rectal cancer has achieved good results. This article provides a review of this field, aiming to provide a basis for personalized treatment of rectal cancer patients.

Background::Understanding willingness to undergo pulmonary function tests (PFTs) and the factors associated with poor uptake of PFTs is crucial for improving early detection and treatment of chronic obstructive pulmonary disease (COPD). This study aimed to understand willingness to undergo PFTs among high-risk populations and identify any barriers that may contribute to low uptake of PFTs.Methods::We collected data from participants in the "Happy Breathing Program" in China. Participants who did not follow physicians’ recommendations to undergo PFTs were invited to complete a survey regarding their willingness to undergo PFTs and their reasons for not undergoing PFTs. We estimated the proportion of participants who were willing to undergo PFTs and examined the various reasons for participants to not undergo PFTs. We conducted univariable and multivariable logistic regressions to analyze the impact of individual-level factors on willingness to undergo PFTs.Results::A total of 8475 participants who had completed the survey on willingness to undergo PFTs were included in this study. Out of these participants, 7660 (90.4%) were willing to undergo PFTs. Among those who were willing to undergo PFTs but actually did not, the main reasons for not doing so were geographical inaccessibility ( n = 3304, 43.1%) and a lack of trust in primary healthcare institutions ( n = 2809, 36.7%). Among the 815 participants who were unwilling to undergo PFTs, over half ( n = 447, 54.8%) believed that they did not have health problems and would only consider PFTs when they felt unwell. In the multivariable regression, individuals who were ≤54 years old, residing in rural townships, with a secondary educational level, with medical reimbursement, still working, with occupational exposure to dust, and aware of the abbreviation "COPD" were more willing to undergo PFTs. Conclusions::Willingness to undergo PFTs was high among high-risk populations. Policymakers may consider implementing strategies such as providing financial incentives, promoting education, and establishing community-based programs to enhance the utilization of PFTs.

Objective:To visualize and analyze the literature related to the treatment of extremity lymphedema (EL) over the years 2012 to 2022 and to explore future research directions.Methods:Taking "lymphedema" and "treatment" as the themes, the study searched the Chinese and English literature related to EL treatment reported by Chinese scholars from 2012 to 2022 in Chinese National Knowledge Infrastructure (CNKI) and Web of Science (WOS) databases, and used CiteSpace software to visualize the literature, draw maps of authors, research institutes, keywords, etc., and carry out clustering and emergent word analysis on the keywords.Results:A total of 1 007 Chinese articles with 16 core authors and 236 English articles with 8 core Chinese authors were included.

Objective:We try to screen out predictive indicators with higher value by analyzing the differences in clinical and laboratory indicators between severe fever with thrombocytopenia syndrome (SFTS) patients in the intensive care unit (ICU) group and non-ICU group.Methods:The clinical and laboratory index data of 69 SFTS patients diagnosed in the laboratory in a hospital from June to December 2019 were retrospectively collected. According to the clinical outcome of the patients, they were divided into ICU and non-ICU groups. The differences in clinical manifestations and laboratory indicators between the two groups were analyzed. The receiver operating characteristic curve (ROC) was used to screen the more valuable predictive indicators.Results:Compared with the non-ICU group, ICU group SFTS patients had significantly higher procalcitonin (PCT), C-reactive protein (CRP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), glutamyl transpeptidase (GGT), leucine aminopeptidase (LAP), glutamate dehydrogenase (GDH), adenosine deaminase (ADA), cystatin C (Cys C), α-hydroxybutyrate dehydrogenase (α-HBDH), creatine kinase (CK), lactate dehydrogenase (LDH) levels ( W=530.0, P=0.003; W=496.5, P=0.015; W=496.0, P=0.015; W=535.5, P=0.002; W=545.5, P=0.001; W=498.5, P=0.013; W=537.0, P=0.002; W=523.0, P=0.004; W=512.0, P=0.007; W=502.0, P=0.012; W=486.0, P=0.023; W=509.0, P=0.008; W=541.0, P=0.002) and significantly lower platelet count (PLT), indirect bilirubin (IBIL), albumin/globulin ratio(A/G) and superoxide dismutase (SOD) levels ( W=199.0, P=0.024; W=175.5.5, P=0.009; t=-2.9, P=0.004; W=209.5, P=0.036; t=-3.0, P=0.004). ROC result showed that ALP [area under the curve (AUC)=0.804, 95% confidence interval ( CI) (0.679~0.929)] and LDH [AUC=0.805, 95% CI (0.680~ 0.930)] have a higher value for predicting the risk of severe illness. Conclusions:Abnormal liver function, heart function, and renal function indicators in SFTS patients indicate that patients are at risk of exacerbation. Among them, ALP and LDH levels have higher predictive value for risk of severe disease, suggesting that the monitoring of patients with the above symptoms should be strengthened in the clinical nursing process.

Objective:To investigate the effect of miR-425-5p on glucagon-like peptide-1(GLP-1) secretion in intestinal L cells induced by lipopolysaccharide(LPS), and to explore its mechanism.Methods:GLUTag cells of intestinal L cell line were incubated with LPS to determine the levels of miR-425-5p and GLP-1. Cell viability was determined by MTT assay, and cell apoptosis was detected by flow cytometry. Quantitative real time-PCR and western blot were performed to determine the expressions of miR-425-5p, phosphatase and tensin homology(PTEN), proglucagon, and GLP-1. Activity of Wnt/β-catenin signaling pathway was determined by detecting TOP/FOP ratio. Interaction among miR-425-5p, PTEN, and β-catenin was analyzed using luciferase activity assay and chromatin immunoprecipitation(ChIP)assay.Results:In GLUTag cells, with the elevation of LPS concentration, the expression of miR-425-5p and the apoptosis rate were increased, while the level of active GLP-1 and the cell viability were decreased. MiR-425-5p was involved in the regulation of LPS on GLP-1 secretion and intestinal L cell viability. Inhibition of miR-425-5p reduced the mRNA expression of proglucagon and the TOP/FOP ratio, increased PTEN protein level, and inhibited cell viability. In LPS-treated GLUTag cells, miR-425-5p increased the level of β-catenin by targeting PTEN, and β-catenin acted as a cis-acting element to induce the transcription of proglucagon and promote the secretion of GLP-1.Conclusion:In LPS-induced intestinal L cells, miR-425-5p promotes the expression of GLP-1 by targeting PTEN to modulate β-catenin.

Objective To observe the effect of new vomit-receiving device in department of neurosurgery. Methods A total of 44 patients with vomiting symptoms in our department in May 2015 were randomly divided into the observation group (n=23) and the control group (n=21). The observation group used a new type of vomit-receiving device to carry out vomiting nursing, while the control group was treated with conventional vomiting nursing. The number of cases of vomiting and the number of occurrence times were observed. Results Observation group of 23 cases with no vomit leaks occur, and the control group 21 patients vomit leaked out in 16 cases, the incidence of vomit were leaked by 72.73% (χ2=27.53, P < 0.01), vomiting leaked rate was 40.74% (22/54) (χ2 = 32.49, P < 0.01), including who prepared to receive tools but not timely for 16 times, receive tools leakage for 5 times, no enough capacity of receive tool for 1 times. The total score of patients′ satisfaction in the observation group was 78, while the total score of patients in the control group was 57. The difference was statistically significant (t=2.80, P＜0.01). The total nursing time of the observation group was 68 min, and that of the control group was 347 min,the difference was statistically significant (t=-5.73, P＜0.01). Conclusions The new vomit-receiving device can effectively reduce the incidence of vomit substance leakage, and the installation is easy to install, easy to operate and conducive to the management of vomit. It greatly improves the efficiency of nursing, and effectively improves the satisfaction of patients and their families to nursing.

Diagnosis of Parkinson's disease (PD) based on speech data has been proved to be an effective way in recent years. However, current researches just care about the feature extraction and classifier design, and do not consider the instance selection. Former research by authors showed that the instance selection can lead to improvement on classification accuracy. However, no attention is paid on the relationship between speech sample and feature until now. Therefore, a new diagnosis algorithm of PD is proposed in this paper by simultaneously selecting speech sample and feature based on relevant feature weighting algorithm and multiple kernel method, so as to find their synergy effects, thereby improving classification accuracy. Experimental results showed that this proposed algorithm obtained apparent improvement on classification accuracy. It can obtain mean classification accuracy of 82.5%, which was 30.5% higher than the relevant algorithm. Besides, the proposed algorithm detected the synergy effects of speech sample and feature, which is valuable for speech marker extraction.

Objective To systematically evaluate the clinical effect of prone position mechanical ventilation on the improvement of oxygenation in patients with severe pneumonia. Methods Pubmed, Embase, Cochrane Library, CNKI, Wanfang Data and VIP database were searched from the time of database built up until December 10th, 2017. All the published randomized controlled trials (RCTs) about the effects of prone position ventilation on the oxygenation of severe pneumonia patients were screened, and were confirmed by the literature reference citation retrieval. Inclusion and exclusion criteria had been used to review and rank the literature. After evaluating the quality of included studies, the data was extracted from RCTs and given a Meta-analysis using RevMen 5.1. Results Twelve RCTs with 650 cases were included. Eleven of them were Chinese literature while 1 was in English. Ten studies showed that the prone position ventilation had a significant influence on improving partial pressure of oxygen [weighted mean difference (WMD) =9.93, 95% confidence interval (95%CI) = 2.92-16.95, P = 0.006], publication bias was found in these studies. Seven studies showed that the prone position ventilation had a significant influence on partial pressure of carbon dioxide (WMD =9.99, 95%CI = 1.81-18.18, P = 0.02), publication bias was found in these studies. Seven studies showed that the prone position ventilation had a significant influence on oxygenation index (WMD = 31.22, 95%CI = 26.06-36.39, P < 0.000 01), publication bias was found in these studies. Two studies showed that the prone position ventilation had a significant influence on oxygen saturation of blood (WMD = 2.12, 95%CI = 1.24-3.00, P < 0.000 01), no publication bias was found in these studies. Conclusion Prone position ventilation can effectively improve the patients' oxygenation index, partial pressure of oxygen, and oxygen saturation of blood, and reduce the partial pressure of carbon dioxide.
