Background Exfoliation syndrome is a systemic disease with abnormal accumulation of extracellular matrix.Oxidative stress and imbalance between matrix metalloproteinases(MMPs) and tissue inhibitor of matrix metalloproteinases(TIMPs)may play an important role in the pathogenesis of exfoliation syndrome.Researches showed that the incidence of exfoliation syndrome is higher in Uyghur nationality than that in Han nationality.However,whether the imbalance of serum MMPs and TIMPs is associated with pathogenesis of different ethnic groups is unclear.Objective The aim of the study was to discuss the change of serum MMP-9 and TIMP-2 in Uyghur patients.Methods This study protocol was approved by Ethic Committee of Xinjiang Medical University and followed Declaration of Helsinki.A prospective cohort study was performed.Forty Uyghur nationality (46 eyes) with exfoliation syndrome were collected from March 2012 to May 2013 in Affiliated First Hospital of Xinjiang Medical University and First People Hospital of Kashi.Forty cases(40 eyes)age-and gender-matched normal volunteers were included in the same duration.The peripheral blood was collected under the informed consent.Serum MMP-9 and TIMP-2 levels were detected by ELISA,and the results between the two groups were compared using independent samples t test.Results Slit-lamp examination found that part of pigmentation was depigmented and white dandrufflike substance attached in the pupil margin in all the patients,and stripping white dandruff-like substance was deposited in the front surface of the lens capsule which distributed in 3 zones.The pupils were disk-shaped pupil,and the surrounding area was the ring granular and the middle was transparent area without ablative material after dilation.Serum MMP-9 levels were (57.88±18.63)μg/L in the exfoliation syndrome group and (9.35±2.78)μg/L in the normal control group;serum TIMP-2 levels were (17.36±4.66) μg/L in the exfoliation syndrome group and (25.73±3.59) μg/L in the control group.The ratios of MMP-9/TIMP-2 were 3.57± 1.45 in the exfoliation syndrome group and 0.37±0.11 in the control group,with statistically significant differences in serum MMP-9 and TIMP-2 levels as well as ratio of MMP-9/TIMP-2 between the two groups(t=11.52,-6.36,9.87,all at P=0.00).Conclusions The upregulation of serum MMP-9 and downregulation of serum TIMP-2 are found in Uyghur patients with exfoliation syndrome.It is verified that the imbalance of serum MMP-9 and TIMP-2 contributes to the pathogenesis of exfoliation syndrome in Uyghur patients.

Objective:To investigate the effects of pulmonary rehabilitation on anxiety/depression and subjective/objective sleep quality of elderly patients with stable chronic obstructive pulmonary disease(COPD).Methods:From February 2018 to February 2019, 120 elderly patients with stable COPD were selected and randomly divided into the experimental group (pulmonary rehabilitation exercise combined with conventional COPD treatment) and the control group (simple COPD conventional treatment). Sixty cases in each group were intervened for 8 weeks. Before and after treatment, Hamilton anxiety scale (HAMA) was used to evaluate anxiety, Hamilton depression scale(HAMD)was used to evaluate depression, Pittsburgh sleep quality index(PSQI)and sleep log were used to evaluate subjective sleep quality, and objective sleep quality was monitored by multi-channel sleep monitor.SPSS 21.0 software was used to analyze and process the data. Chi square test, independent sample t test and paired t test were used for statistical analysis. Results:After 8 weeks of intervention, the HAMA and HAMD scores of the experimental group were lower than those of the control group (HAMA: (7.57±3.19) vs (10.15±4.89), t=-3.428, P=0.001; HAMD: (8.22±4.73) vs (10.60±6.49), t=-2.300, P=0.023). COPD patients with anxiety decreased (χ 2=7.566, P=0.006). After treatment, the subjective sleep latency of the experimental group was shorter than that of the control group ((42.00±9.88)min vs (47.25±10.27)min, t=-2.854, P=0.005). The subjective sleep efficiency was higher than that of the control group ((76.00±4.50)% vs (74.00±5.20)%, t=2.272, P=0.025), and the objective sleep latency was shorter than that of the control group ((28.02±5.59)min vs (32.95±6.21)min, t=-4.575, P<0.05). Conclusion:Pulmonary rehabilitation exercise can improve the anxiety and depression of elderly patients with stable COPD, and improve the subjective and objective sleep quality.

Objective To evaluate the effectiveness of exercise rehabilitation intervention by using self-efficacy theory on patients with chronic stable heart failure, and to provide evidences for rehabilitation nursing of patients. Methods Using the method of randomized controlled studies, 132 patients with chronic stable heart failure from Nanshitou Street and Shayuan Street communities in Haizhu, Guangzhou, Guangdong were randomly divided into two groups according to the community's name. The patients in the intervention group received self-efficacy and education intervention while the control group received health education only. The patients' exercise self-efficacy scores and six minute walk distances were separately measured by exercise self-efficacy scale and six minute walk test before and after intervention. Results The scores of exercise self-efficacy and six minute walk distances increased more significantly in the intervention group than in the control group after intervention (P<0.01). Conclusion Self-efficacy and education intervention can effectively improve the exercise self-efficacy and six minute walk distance of patients with heart failure.

Objective To investigate the difference between structured triglyceride(STG)and Non-structured triglyceride(NSTG)in nutritional support for perioperative patients.Methods A nationwide survey was conducted through online questionnaire.The questionnaire consisted of four modules:questionnaire information,patient information,prescription investigation and postoperative observation.SPSS 24.0 software was used for statistical analysis.Results Before and after parenteral nutrition(PN),the average levels of albumin(ALB)increased in both groups(P＜0.01),while the levels of C-reactive protein(CRP)and alanine aminotransferase(ALT)decreased(P＜0.01).The difference in serum triglyceride(TG)levels in the STG group was not statistically significant,while there was a decrease in the NSTG group(P＜0.05).Generalized linear equation analysis of repeated measurements showed that compared to the NSTG group,the increase in ALB levels in the STG group patients was more significant(P＜0.001),CRP and ALT decreases were more pronounced(P＜0.001),but the impact on TG was smaller.Conclusions For perioperative patients with parenteral nutrition,STG supplementation can bring significant clinical benefits.STG should be used according to the organ function and economic situation of patients.

Background:At present,domestic guidelines and consensus recommend the use of nutritional risk screening 2002(NRS 2002)and patient-generated subjective global assessment(PG-SGA)for nutritional risk screening and assessment of patients with gastrointestinal cancer during the perioperative period.However,PG-SGA has higher professional requirements,complex content and time-consuming.In the current busy situation of medical staff,NRS 2002 is more used for screening alone.Aims:To explore the consistency of NRS 2002 and PG-SGA in the assessment of nutritional status and clinical outcomes in patients with gastrointestinal malignancies,and to explore the accuracy of screening using NRS 2002 alone,so as to provide guidance for the establishment of clinical nutritional screening and assessment standards.Methods:A retrospective analysis was conducted on 157 patients with gastrointestinal malignancies who underwent radical operation in the Department of Gastrointestinal Surgery of Xiangya Hospital,Central South University from January 2020 to October 2022.Nutritional screening and evaluation were performed by NRS 2002 and PG-SGA scales and demographic data and nutrition-related laboratory indicators were collected to observe short-term postoperative clinical outcomes.Results:Patients with nutritional risk or malnutrition had lower body mass index(BMI),lymphocytes and prealbumin(P<0.05).The correlation and consistency of NRS 2002 and PG-SGA scales were good(r=0.728,κ=0.46)and the areas under the curve(AUC)for predicting postoperative complications were 0.691 and 0.702,respectively.In addition,nutritional risk and postoperative complications were significantly increased in patients with malnutrition(P<0.05).Conclusions:Therefore,gastrointestinal surgeons can only use NRS2002 to perform nutritional screening of patients and make corresponding nutritional treatment according to the screening results in the case of busy clinical work.

Objective: To investigate the willingness to accept preventive treatments and its related factors among college freshmen with latent tuberculosis infection (LTBI), so as to provide the evidence for preventive treatment intervention measures for students with LTBI. Methods: Cluster sampling method was used to select 368 LTBI freshmen from 8 colleges and universities in Changzhou in September 2023, who conducted a questionnaire survey on the willingness to receive preventive treatment. General demographic data were collected and relevant data were collected using tuberculosis knowledge scale, General Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), Adaptation, Partnership, Growth, Affection and Resolve (APGAR), and a self developed Stigma Scale. A binary Logistic regression model was constructed with the willingness to accept preventive treatment as the dependent variable to analyze the willingness to accept preventive treatment and the influencing factors. Results: A total of 253 LTBI college freshmen were willing to take preventive treatment, the acceptance rate was 68.75%. The rate of willingness to accept preventive treatment for LTBI was higher among students whose fathers had an education level of high school, compared to those whose fathers had an education level of junior high school or below ( OR =2.16, P <0.05). LTBI students whose per capita family income was >5 000-10 000 yuan and >10 000 yuan were more willing to accept LTBI preventive treatment than those whose per capita family income was <3 000 yuan ( OR =2.72, 4.46, P <0.05). LTBI students who engaged in physical exercise for more than 2 hours per week were more willing to accept than those who exercised less than 0.5 hours per week ( OR =1.91, P <0.05). LTBI students with high levels of tuberculosis knowledge and stigma were more likely to receive preventive treatment ( OR =1.18, 1.11, P < 0.05). LTBI students with high PHQ-9 ( OR =0.85) and GAD-7 ( OR =0.92) scores were more likely to refuse preventive treatment ( P <0.05). Conclusion The present study revealed a moderate level of willingness of LTBI students to preventive treatment in Changzhou City, and the acceptance is affected by family factors, healthy lifestyles, tuberculosis knowledge and psychological status.
