Objective:To explore the utility of a robotic trunk support brace (a RoboBDsys) in evaluating seated trunk control after a spinal cord injury (SCI).Methods:Twenty wheelchair-dependent SCI patients were tested for trunk resistance while seated and wearing the RoboBDsys. In the test they were required to maintain an upright seated position for 1 minute while external forces were applied from the left, right, anterior and posterior directions. The system generated eight observations of swings of the center of pressure (COP), their mean velocity and their standard deviations. Sway area, sway path (SP), mean sway frequency (MF) and mean sway amplitude (MA) were also recorded along with the maximum voluntary contraction torque (MVC). The trunk control test (TCT), the Tinetti Balance Scale (Tinetti), the modified Functional Reach Test (mFRT) and Spinal Cord Independence Measure III (SCIM-III) were also administerd and their results were correlated with the RoboBDsys resistance test results.Results:All twenty of the patients completed the resistance test in the left and right directions, but only 11 did it in the anterior and posterior directions. In the left and right-direction resistance tests the average center of pressure deviation, sway area and MVC showed some significant correlation with the TCT, Tinetti, mFRT and SCIM-III results (| r| ranging from 0.46 to 0.74). The average MVC in the anterior-direction correlated moderately with the TCT, mFRT and SCIM-III results (| r|=0.63 to 0.67), while that in the posterior-direction had moderate correlation with the TCT and mFRT results only (| r|=0.63 to 0.67). Conclusion:The Robotic Brace for Dynamic Trunk Support system can be effective in assessing reactive postural control and functional independence after a spinal cord injury.

Objective To construct home-based rehabilitation nursing program for elderly patients with chronic obstructive pulmonary disease based on functional physical fitness index.

The expert consultation questionnaire was prepared, and 12 experts related to respiratory and rehabilitation were selected through group discussion, and two rounds of expert consultation were conducted. Results The recovery rate of the two rounds of expert consultation questionnaires was 83.3 % for both rounds, with an expert authority coefficient of 0.90. The home-based rehabilitation nursing program consists of four primary indicators, eleven secondary indicators, and thirty-three tertiary indicators. Conclusion The home-based rehabilitation nursing program for elderly patients with chronic obstructive pulmonary disease constructed based on functional physical fitness is feasible, scientific and innovative, which can provide theoretical basis for clinical application.

Monascus is one of the most essential microbial resources in China, with thousands of years of history. Modern science has proved that Monascus can produce pigment, ergosterol, monacolin K, γ-aminobutyric acid, and other functionally active substances. Currently, Monascus is used to produce a variety of foods, health products, and pharmaceuticals, and its pigments are widely used as food additives. However, Monascus also makes a harmful polyketide component called citrinin in the fermentation process; citrinin has toxic effects on the kidneys such as teratogenicity, carcinogenicity, and mutagenicity (Gong et al., 2019). The presence of citrinin renders Monascus and its products potentially hazardous, which has led many countries to set limits and standards on citrinin content. For example, the citrinin limit is less than 0.04 mg/kg according to the Chinese document National Standard for Food Safety Food Additive Monascus (GB 1886.181-2016) (National Health and Family Planning Commission of the People's Republic of China, 2016), and the maximum level in food supplements based on rice fermented with Monascus purpureus is 100 µg/kg in the European Union (Commission of the European Union, 2019).

Colorectal cancer （CRC）， as the third most common cancer in the world， develops from the colonic and rectal epithelial cells. With the rapid development of the global economy， the incidence of CRC in developing countries has been increasing year by year. In the past few years， although preventive colonoscopy screening has improved the survival rate of CRC patients， the majority of cases are still detected after symptoms appear. Currently， the clinical treatment of CRC carries high surgical risks and is prone to recurrence， while radiotherapy and chemotherapy have significant side effects and cause a heavy psychological burden on patients. Therefore， there is currently no ideal treatment protocol for CRC. The phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） pathway， as a classical oncogenic pathway， provides potential for the diagnosis and treatment of various malignant diseases， and offers a new direction for the treatment of CRC. In recent years， traditional Chinese medicine （TCM） has become a major focus in cancer treatment due to its advantages in "preventing and treating diseases" and its multiple components， targets， and pathways. Its advantages in having fewer side effect complement western medicine in treatment. Multiple studies have shown that Chinese medicinal monomers and compound formulas can inhibit the proliferation， invasion， migration， and angiogenesis of CRC cells， promote apoptosis and autophagy of cancer cells， and slow down the development of CRC by intervening in the PI3K/Akt signaling pathway， thereby achieving the therapeutic effect on CRC. In recent years， the research progress related to this has been updating rapidly. Previous literature failed to timely incorporate the latest research results， which brought many inconveniences to the literature search of many scholars. Therefore， this article summarized the relevant information from PI3K/Akt pathway， the association between the PI3K/Akt pathway and CRC， and the progress of TCM intervention in the treatment of CRC to provide references for the development of CRC in molecular biology and the clinical development of new drugs in the future.

Objective:To investigate the test-retest reliability and criterion validity of the Robotic Brace for Dynamic Trunk Support System(RoboBDsys)in evaluating seated trunk control function in patients with spinal cord in-jury(SCI). Method:From October to December,2022,20 patients with spinal cord injury who were unable to walk were recruited.All participants completed RoboBDsys trunk control test including static control test and dynam-ic control test on the seated platform.The evaluation indexes were the supporting torque regression slope exert-ed by the robot platform on the direction of x,y,α,and θ,recorded as Kx,Ky,Kθ,Kα;the average sup-porting torque recorded as Fx,Fy,Mθ,Mα in the static control test;and the the Range of Motion(ROM)of trunk in four directions in the dynamic control test.All the participants completed Trunk Control Test(TCT)as criterion assessment.The test interval was one week,intraclass correlation coefficient(ICC)values were calculated between two RoboBDsys trunk control test. Result:There were 13 participants completed two tests.In the static control test,the ICCs of four indexes were 0.418-0.742 between 2 tests;the ICCs of all indexes in dynamic control test were 0.633-0.848,which all showed moderate to high test-retest reliability.In regards of criterion validity,there was low to mod-erate correlation between Ky,Mθ,Mα in static control test and TCT(|r|=0.467-0.561,P＜0.05);all indexes except right lateral flection ROM in dynamic control test showed moderate to high correlation with TCT(r=0.559-0.758,P＜0.05). Conclusion:RoboBDsys is a reliable and valid tool for evaluating seated trunk control function in patients with SCI.

Background::High-dose dual therapy (HDDT) with proton pump inhibitors (PPIs) and amoxicillin has attracted widespread attention due to its favorable efficacy in eradicating Helicobacter pylori ( H. pylori). This study aimed to compare the efficacy and safety of high-dose PPI–amoxicillin dual therapy and bismuth-containing quadruple therapy for H. pylori rescue treatment. Methods::This was a prospective, randomized, multicenter, non-inferiority trial. Patients recruited from eight centers who had failed previous treatment were randomly (1:1) allocated to two eradication groups: HDDT (esomeprazole 40 mg and amoxicillin 1000 mg three times daily; the HDDT group) and bismuth-containing quadruple therapy (esomeprazole 40 mg, bismuth potassium citrate 220 mg, and furazolidone 100 mg twice daily, combined with tetracycline 500 mg three times daily; the tetracycline, furazolidone, esomeprazole, and bismuth [TFEB] group) for 14 days. The primary endpoint was the H. pylori eradication rate. The secondary endpoints were adverse effects, symptom improvement rates, and patient compliance. Results::A total of 658 patients who met the criteria were enrolled in this study. The HDDT group achieved eradication rates of 75.4% (248/329), 81.0% (248/306), and 81.3% (248/305) asdetermined by the intention-to-treat (ITT), modified intention-to-treat (MITT), and per-protocol (PP) analyses, respectively. The eradication rates were similar to those in the TFEB group: 78.1% (257/329), 84.2% (257/305), and 85.1% (257/302). The lower 95% confidence interval boundary (–9.19% in the ITT analysis, –9.21% in the MITT analysis, and –9.73% in the PP analysis) was greater than the predefined non-inferiority margin of –10%, establishing a non-inferiority of the HDDT group vs. the TFEB group. The incidence of adverse events in the HDDT group was significantly lower than that in the TFEB group (11.1% vs. 26.8%, P < 0.001). Symptom improvement rates and patients’ compliance were similar between the two groups. Conclusions::Fourteen-day HDDT is non-inferior to bismuth-containing quadruple therapy, with fewer adverse effects and good treatment compliance, suggesting HDDT as an alternative for H. pylori rescue treatment in the local region. Trial registration::Clinicaltrials.gov, NCT04678492.

Objective:To translate Career Success in Nursing Scale (CSNS) into Chinese and evaluate the reliability and validity of it.Methods:According to the translation principle of Brislin questionnaire, the English version of CSNS was translated, back-translated and culturally adjusted to determine the simplified Chinese version of CSNS items and form the Chinese version of CSNS. A total of 1 489 nurses from China-Japan Friendship Hospital were selected as the research objects from May to June 2021. The general information questionnaire and simplified Chinese version of CSNS were used to investigate them. Internal consistency and split-half reliability coefficient were used to evaluate the reliability of the scale. Pearson correlation analysis was used to analyze the correlation between each dimension and the relationship between each dimension and the total scale. A total of 1 489 questionnaires were collected and 1 434 valid questionnaires were collected, with an effective recovery rate of 96.3%.Results:The Chinese version of CSNS included 4 dimensions, such as "desired career development" "providing quality care" "effective self-regulation" and "fit between human and organization" , with a total of 39 items. The expert content validity was 0.984. The results of exploratory factor analysis showed that the cumulative variance contribution rate of the four common factors was 74.71%. The Cronbach's α coefficient of the total scale was 0.985 and the Cronbach's α coefficient of each dimension was 0.955-0.979. The split-half reliability of the total scale was 0.986 and the split-half reliability of each dimension was 0.957-0.979. The test-retest reliability of the scale was 0.966.Conclusions:The Chinese version of CSNS scale has good reliability and validity, which can be used to evaluate the psychological characteristics of nurses' career success.

Cardio-cerebrovascular disease (CCVD) is a major comorbidity of Coronavirus disease 2019 (COVID-19). However, the clinical characteristics and outcomes remain unclear. In this study, 102 cases of COVID-19 from January 22, 2020 to March 26, 2020 in Xixi Hospital of Hangzhou were included. Twenty cases had pre-existing CCVD. Results showed that compared with non-CCVD patients, those with CCVD are more likely to develop severe disease (15% versus 1%), and the proportion of pneumonia severity index grade IV was significantly higher (25% versus 3.6%). Computed tomography images demonstrated that the proportion of multiple lobe lesion involvement was significantly higher in the CCVD group than in the non-CCVD group (90% versus 63.4%). Compared with non-CCVD group, the levels of C-reactive protein, fibrinogen, D-dimer, and serum amyloid-A were higher, whereas the total protein and arterial partial PaO

Objective:To investigate the immunogenicity and safety of a boost dose of measles, mumps, and rubella combined vaccine (MMR) for children 4 to 6 years old.Methods:Children, aged 4 to 6 years old, had vaccinated with 1 dose of measles and rubella combined vaccine(MR) at the age of 8 months and 1 dose of MMR vaccine at 18-months, were recruited in Shanxi, Inner Mongolia, and Beijing, respectively. All children were assigned into 4, 5 and 6-year-old group. The children who met inclusion and exclusion criteria were vaccinated with 1 dose MMR vaccine, and were collected blood samples before vaccination and 35 to 42 d after the vaccination. During the study period, adverse events were collected at 30 min, 1 d, 2 d, 3 d, 4-12 d, and 13 to 42 days after vaccination. Serum was tested for IgG antibodies against measles, mumps and rubella. Geometric mean concentrations (GMC) of measles, mumps, and rubella antibodies were compared among groups by analysis of variance or non-parametric test. Seropositive rates and adverse event rates were compared among groups by Chi-square test or Fisher exact test.Results:A total of 500 children were included in immunogenicity analysis and 535 children were included in safety analysis. The overall adverse event rate was 20.37%, the most of severity for adverse events was mild. The rates of local and systemic adverse events were 0.37% and 20.00%, respectively. Symptoms of local adverse events were redness. The main systemic adverse events were fever, followed by cough, rash and runny nose. Received a dose of MMR vaccine for booster immunization, the seropositive rates of measles antibody, mumps antibody and rubella antibody were above 99% for all 3 age groups, and there was no significant difference between groups. There were significant differences in mumps antibody GMC among groups ( P=0.042), but no significant differences in measles and rubella antibodies GMC. Conclusion:The immunogenicity and safety of a boosted MMR vaccintion in children aged 4, 5 and 6 years were all similar good.

Objective? To understand the knowledge of influenza among inpatients before health education and intervention using the sensitive indicators in nursing outcomes. Methods? Using convenience sampling method, 400 inpatients from November 2018 to February 2019 in China-Japan Friendship Hospital were selected as the research objects. Referring to the two outcomes indicators of "knowledge: disease process" and"knowledge: control of infection" in the Classification System of Nursing Outcomes, a Knowledge Questionnaire on Influenza Susceptibility Indicators of Inpatients was developed to investigate and analyze influenza sensitive indicators. A total of 392 valid questionnaires were collected. Results? The 392 patients' scoring rate of Knowledge Questionnaire on Influenza Susceptibility Indicators of Inpatients was 48.1%. There was no significant difference in Knowledge Questionnaire on Influenza Susceptibility Indicators of Inpatients scores among patients of different ages, gender, educational background, living environment and occupation (P＞0.05), all of them had low scores. In the single analysis, there were statistically significant differences in the scores of "influenza symptoms and signs" among patients of different ages, gender, educational background, living environment and occupations (P＜0.05). There were significant differences in the knowledge of "influenza transmission mode" among patients living in different environments (P＜ 0.05). Compared with the two dimensions of "disease process" and "infection control", the score of "disease process" was higher than that of "infection control", and the difference was statistically significant (P＜0.01). Conclusions The situation of understanding sensitive indicators of flu in the inpatients is not very well, the evaluation based on nursing outcome sensitive indicators can help medical staff to understand the inpatients' real status on flu-related knowledge, self-protection awareness, and behaviour and to provide reference of the following health education and prevention management.
