Objective To analyze the prognosis of elderly patients with community-acquired pneumonia (CAP) and its correlation with serum angiopoietin 2 (Ang-2), activated protein C (APC) and pentraxin 3 (PTX3) levels. Methods A total of 508 elderly patients with CAP in the hospital from March 2021 to March 2024 were divided into death group (n=104) and survival group (n=404) according to the survival status at 28 days after admission. Another 110 healthy subjects with physical examination were included in the control group. The levels of serum Ang-2, APC and PTX3 were compared, and their correlation with prognosis was explored by Pearson correlation analysis. Results In this study, 404 cases survived after 28 days and 104 cases died. The levels of C-reactive protein, procalcitonin and interleukin-8 and the proportion of severe condition in the survival group were lower than those in the death group (P<0.05). The level of serum APC in the case group and the death group was lower than that in the control group and the survival group (P<0.05), while the levels of Ang-2 and PTX3 were higher than those in the control group and the survival group (P<0.05), respectively. Serum APC level was negatively correlated with community-acquired pneumonia in the elderly CAP (r=-0.476, P<0.05), while Ang-2 and PTX3 were positively correlated with prognosis (r=0.489, 0.502, P<0.05). Conclusion Serum levels of Ang-2 and APC in elderly patients with CAP are decreased and the level of PTX3 is increased. Serum Ang-2 and APC levels are negatively correlated with elderly CAP, and PTX3 is positively correlated with prognosis.

Objective: To investigate the level of mental heath literacy and influencing factors among grassroots mental heath workers in Xinjiang Uygur Autonomous Region, so as to provide insights into relevant intervention measurements. Methods: Full-time (part-time) grassroots mental heath workers were sampled from grassroots healthcare institution (community health service centers and township health institutes) in Xinjiang Uygur Autonomous Region. Participants&#39; demographics and achievements of the target for mental heath literacy were collected through self-designed questionnaires and the Mental Health Literacy Questionnaire, and factors affecting the achievements of the target for mental heath literacy were identified using a multivariable logistic regression model. Results: A total of 3 382 respondents were recovered, including 771 males (22.80%) and 2 611 females (77.20%), and had a mean age of (35.59±9.21) years. There were 491 respondents that met the target of the mental health literacy (14.52%). Multivariable logistic regression analysis showed that grassroots mental heath workers who were Han Ethnicity (OR=2.735, 95%CI: 2.166-3.454), had high levels of education (college, OR=1.722, 95%CI: 1.299-2.283; bachelor degree and above, OR=2.681, 95%CI: 1.966-3.656), worked at community health service centers (OR=1.435, 95%CI: 1.142-1.803), physician (OR=1.877, 95%CI: 1.239-2.843) and engaged in mental health prevention and treatment for 2 to <5 years (OR=1.388, 95%CI: 1.059-1.818) were more likely to meet the target of the mental health literacy. Conclusion The proportion of achieving the target for mental health literacy is low among grassroots mental health care workers in Xinjiang Uygur Autonomous Region, and ethnicity, educational level, organization category, occupation and service length of mental health prevention and treatment are the influencing factors.

The number of investigator initiated research (IIR) is increasing. But the recognition and management of IIR in China is still in its infancy, and there is a lack of specific and operable guidance for the implementation process. Based on our practical experiences, previous literature reports, and current policy regulations, the authors took prospective IIR as an example to summarize the implementation process of IIR into 14 steps, which are as the following: study initiation, ethical review, study registration, study filing, case report form design, database establishment, standard operating procedure making, investigator training, informed consent, data collection, data entry, data verification, data locking and data archiving.

With the development of science and the progress of society,a revolutionary breakthrough-optical coherence tomography angiography(OCTA), a non-invasive imaging-assisted examination method-has been achieved, in the study of hemodynamics of the fundus of primary glaucoma in recent years. This technology has many advantages compared with previous traditional inspection methods. It fully exercises split-spectrum amplitude decorrelation angiography(SSADA)to acquire three-dimensional blood flow images of the fundus. With characteristics of none invasion but fastness, repeatability, layered imaging and high resolution, it can stratify and quantify the fundus blood flow density, and is also used to monitor the early changes of glaucoma fundus blood flow, disease progression and evaluation of therapeutic effect. However, OCTA presents certain shortcomings in actual clinical applications. Before available to function more widely in the fields of glaucoma disease, this method demands further researches and development. This article gives an overview of the application and research progress of OCTA technology in primary glaucoma.

Objective    To compare the clinical efficacy of modified Ivor-Lewis esophagectomy, which preserves azygos vein, thoracic duct and peripheral tissues, and classic Ivor-Lewis esophagectomy, which resects these tissues, in the treatment of esophageal cancer, so as to evaluate whether it is necessary to resect azygos vein, thoracic duct and peripheral tissues in esophagectomy for esophageal cancer. Methods    Patients scheduled for surgical treatment of thoracic esophageal cancer in Department of Thoracic Surgery of Sichuan Cancer Hospital from June 2011 to June 2013 were randomly assigned to the retention group and the resection group, each including 100 patients. The retention group included 87 males and 13 females with an average age of 60.53±7.72 years. In the resection group, there were 80 males and 20 females with an average age of 60.69±7.69 years. Patients in the two groups were compared for the duration of surgery, intraoperative blood loss, postoperative thoracic drainage volume, postoperative complications, and number of dissected lymph nodes, etc. Postoperative relapse and survival rates at 1, 3 and 5 years postoperatively were also followed up and compared for patients in the two groups. Results    There was no statistical difference between the two groups in general patient characteristics, number of dissected lymph nodes, or postoperative pathological stage, etc. (P>0.05). Compared to the resection group, there were shorter duration of surgery, less intraoperative blood loss, and less thoracic drainage   volume in the first 3 days following surgery in the retention group, with statistical differences (P<0.05). There was no statistical difference between the two groups in type or site of relapse or metastasis (P>0.05). The survival rates at 1, 3, and 5 years postoperatively was 78.7% vs. 81.3%, 39.4% vs. 37.5%, and 23.4% vs. 17.7%, respectively, in the retention group and the resection group, with no statistical difference (P>0.05). Conclusion    Modified Ivor-Lewis esophagectomy preserving azygos vein, thoracic duct and peripheral tissues could reduce surgical trauma, would not increase postoperative relapse or metastasis, and could produce long-term efficacy comparable to that of extended resection.
