AIM: To observe the preliminary application of fully automatic feedback perimeter based on the eye gaze tracking technique in the college students and to verify its test performance.METHODS: Home computer, monitor and eye tracker were used to complete the new automatic feedback perimeter meter. Based on the two characteristic eye movements of fixation and pulsation, the abnormal visual field is determined by analyzing whether the participant perceives the visual target, line-of-sight scan path and the fixation towards the visual target. RESULTS: A total of 63 participants(119 eyes)were collected with valid eye movement data. The average time for all participants was 82.46±14.68 s, the average time for right eyes was 88.21±15.30 s, and average time for the left eyes was 76.42±11.29 s(P<0.05).CONCLUSION: The fully automatic feedback perimeter based on eye gaze tracking technique can realize automatic human-computer interaction, and the detection method is simple and easy, which shortens the time of perimetry and improves the experience of participants.

Tuberculosis is a zoonotic disease posing a substantial public health threat.Immunological diagnosis and vaccine im-munization are both necessary to control tuberculosis prevalence.However,the identical antigenic components in diagnostic reagents and vaccines hinder the use of animal vaccines and limit the specificity of clinical diagnosis in humans.Differentiating infected from vaccinated animals can overcome these problems.This article reviews the progress in differential diagnosis research from three as-pects:the diagnostic effects of antigens,methods for discovering new antigens,and screening of new host immune markers,to provide a theoretical basis for future research.

Objective:To explore latent class of symptoms related to psychological trauma and characteristics in patients with pregnancy loss, and to analyze the related influencing factors.Methods:From July 2022 to June 2024, a convenience sampling method was used to select 709 cases of pregnancy loss patients who visited the Maternity Department of the First Affiliated Hospital of Zhengzhou University as the survey subjects. The survey was conducted using the general information questionnaire, the post-traumatic stress disorder (PTSD) self-assessment scale, the hospital anxiety and depression scale, and the pittsburgh sleep index scale. Exploratory latent class analysis (LCA) of symptoms related to psychological trauma was performed by Mplus8.3, and then multivariate logistic regression was used to identify the factors influencing the latent classes.Results:A total of 691 patients with pregnancy loss were eventually investigated, with a total PTSD score of 24.00 (19.00, 33.00), a total anxiety score of 6.00 (3.00, 9.00), a total depression score of 6.00 (3.00, 9.00), and a total sleep disorder score of 7.00 (4.00, 9.00). Symptoms related to psychological trauma could be classified into 3 potential categories named high symptom group [20.4% (141/691)], anxiety-depression group [15.3% (106/691)] and low symptom group [64.3% (444/691)]. The result of multivariate logistic regression analysis showed that per capita monthly household income >8 000 yuan ( OR=0.477, 95% CI: 0.272-0.835, P=0.010) and having a spouse accompanying the patient at the time of admission ( OR=0.352, 95% CI: 0.234-0.532, P<0.001) were protective factors for the high symptom group, and gestational week≥28 weeks ( OR=3.192, 95% CI: 1.619-6.292, P=0.001) and assisted reproductive pregnancy ( OR=1.877, 95% CI: 1.075-3.277, P=0.027) were risk factors for the high symptom group. Conclusion:Symptoms associated with psychological trauma in patients with pregnancy loss have distinct categorical characteristics, and healthcare professionals should focus on patients with pregnancy loss in the high symptom group during hospitalization, and adopt targeted interventions according to the symptoms related to psychological trauma in different categories of patients with pregnancy loss in order to avoid serious psychological problems.

Objective:To investigate the efficacy of low-methoxyl pectin (LMP) combined with early enteral nutrition (EEN) in patients with severe acute pancreatitis (SAP) complicated by acute kidney injury (AKI).Methods:A prospective study was conducted, enrolling 85 patients with SAP complicated by AKI admitted to the First Hospital of Qinhuangdao from January 2022 to December 2023. These patients were randomized into an LMP group ( n=42) and a control group ( n=43) using a random number table. The control group received traditional EEN, while the LMP group received traditional EEN combined with LMP. Nutritional indicators [total protein (TP), albumin (Alb), and prealbumin (PA)], inflammatory markers [C-reactive protein (CRP), interleukin (IL)-1, IL-6, IL-8, and tumor necrosis factor-α (TNF-α)], renal function indicators [creatinine (Cr), estimated glomerular filtration rate (eGFR), blood urea nitrogen (BUN), uric acid (UA)], AKI stage, and fecal intestinal flora were compared between these two groups before and 7 days after intervention. Results:After 7 days of intervention, the TP, Alb, and PA levels significantly increased in both groups (all P<0.05); the increases in TP and PA were more significant in the LMP group (both P<0.05), whereas the increase in Alb did not differ significantly between groups ( P>0.05). The levels of CRP, IL-1, IL-6, IL-8, and TNF-α decreased significantly in both groups (all P<0.05),with more significant reductions in the LMP group (all P<0.001). The levels of Cr, eGFR, BUN, and UA improved significantly in both groups (all P<0.05),with more significant improvements in the LMP group (all P<0.05). The incidence of a higher AKI stage in the LMP group was significantly lower than that in the control group( P<0.05), and the incidence of a lower AKI stage was significantly higher than that in the control group ( P<0.001). The fecal counts of Bifidobacterium and Lactobacillus increased significantly while the fecal counts of Enterococcus and Enterobacter decreased significantly in both group (all P<0.001); notably, these changes in bacterial counts were significantly more pronounced in the LMP group ( P<0.001). Conclusions:EEN combined with LMP can significantly enhance nutritional status, reduce inflammatory response, and improve renal function in patients with SAP complicated by AKI.

OBJECTIVE: To explore the feasibility of establishing a temporary trauma team led by trauma experts in primary hospitals for disaster medical rescue. METHODS: In the coal mine flooding accident in Xiaoyi City, Shanxi Province on December 15, 2021, according to the local emergency plan and the characteristics of the accident, the trauma experts trained the medical staff from the local primary hospital on advanced trauma life support (ATLS) and damage control surgery (DCS) in the short time interval between the occurrence of the mine disaster and the admission of medical staff to the disaster scene. A temporary trauma team composed of trauma experts, ATLS team, and DCS team was formed to provide early diagnosis and treatment for survivors before and in the hospital. RESULTS: The miners were found on the 36th hour of the disaster. All 22 miners were male, and 2 died underground. Another 20 people were rescued 39－43 hours after the disaster, with a median age of 48 years (34-57 years). All the survivors suffered from hypothermia, dehydration, maceration of feet and other injuries. There were 18 cases of acute inhalation tracheobronchitis, 14 cases of electrolyte acid-base disturbance, 6 cases of trunk contusion, 1 case of psoas major hematoma, and 1 case of lower extremity hematoma. Deep vein thrombosis was in 4 cases. The ATLS team focused on injury assessment, rewarming and rehydration within 50－60 minutes before admission, and completed auxiliary examinations within 2 hours after admission to clarify the diagnosis. The DCS team evaluated 6 patients with mechanical blunt trunk injury and excluded the indication of emergency surgery. The trauma experts conducted the whole process of supervision and quality control of disaster rescue. The positive rate of capillary refill test in the all survivors at the third hour of admission was significantly lower than that immediately after being rescued (75.0% vs. 15.0%, P=0.000 3), and they were discharged 4－7 days after admission. CONCLUSION Under the leadership of trauma experts and relying on the medical staff of primary hospitals, it is feasible to establish and train a temporary trauma team with ATLS and DCS functions to participate in the medical rescue of disasters, which is in line with the current national conditions of China.

The Healthy China 2030 Plan set the goal of reducing premature deaths from diabetes by 30% by 2030. However, there has been a lack of assessment of premature mortality for diabetes since the action plan was issued. This study used data from the Global Burden of Disease Study 2021, calculated the premature deaths for diabetes by sex, provinces, and subtypes from 1990 to 2021. We explored the temporal trend of premature mortality using the average annual percent change (AAPC) for different sexes, provinces, and subtypes from 1990 to 2021. Furthermore, we predicted premature mortality for diabetes through 2030 for China and its provinces according to the average annual change rate from 2010 to 2021. There was a first slow upward trend in premature mortality for diabetes from 0.5% in 1990 to 0.6% in 2004, and then a decline until 2021 with premature mortality of 0.4%. By 2030, only Fujian (30.3%) will achieve the desired level of reduction, with only seven provinces meeting the target for females and none for males. There is a large range in the degree of decline between inland and coastal regions, showing obvious geographic differences, and there should be a focus on balancing medical resources.
