Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Objective:To investigate the prevalence and genotype distribution of human papillomavirus (HPV) infection in the anorectal region among human immunodeficiency virus (HIV)-positive men who have sex with men (MSM) in Shenzhen, and explore the differences between HIV-positive and HIV-negative MSM populations, providing scientific evidence for HPV screening, vaccination, and related disease prevention.Methods:A total of 100 MSM recruited from the Department of Dermatovenerology of the Third People′s Hospital of Shenzhen between 2023 and 2024 were included. Questionnaire collected sociodemographic and clinical characteristics. Anorectal exfoliated cells were analyzed for HPV genotyping, and blood samples were tested for HIV antibodies and T lymphocyte subsets. Chi-square test was used to assess associations between qualitative variables. Results:Among 100 MSM, 58 were HIV-positive and 42 HIV-negative. The overall HPV infection rate was 93.10% (54/58) in HIV-positive MSM, with high-risk HPV at 79.31% (46/58) and low-risk HPV at 75.86% (44/58). The predominant genotypes were HPV6, 11, 16, 52, 18, 59, and 68. In HIV-negative MSM, HPV infection rate was 95.24% (40/42), with high-risk HPV at 57.14% (24/42) and low-risk HPV at 92.50% (37/40), dominated by HPV6, 11, 16, 51 and 52. HIV-positive MSM showed significantly higher infection rates of high-risk HPV16/18 ( P=0.032), HPV58 ( P=0.020), HPV59 ( P=0.031), and HPV68 ( P=0.007) compared to HIV-negative MSM. The maximum number of concurrent HPV infections was 12 in HIV-positive MSM versus 4 in HIV-negative MSM. Multivariate analysis revealed that HIV-positive MSM with CD4/CD8 ratio≤0.9 had significantly higher HPV positivity ( P<0.05). Conclusions:HIV-positive MSM exhibit elevated rates of high-risk and multiple HPV infections, closely associated with immune dysfunction. Strengthened HPV screening, vaccination, and immune status management are critical for preventing HPV-related malignancies in the population.

OBJECTIVE: To evaluate the effectiveness and safety of minimally invasive treatment for bilateral tibial plateau fractures using the double reverse traction reducer. METHODS: The clinical data of 4 patients with bilateral tibial plateau fractures who met the selection criteria and treated between January 2016 and April 2024 were retrospectively analyzed. The cohort included 3 males and 1 female, aged 30-65 years (mean, 52.5 years). Injury mechanisms comprised traffic accidents (2 cases) and falls (2 cases). According to the Schatzker classification, 2 limbs were type Ⅱ and 6 were type Ⅵ. The time from injury to surgery ranged from 5 to 9 days (mean, 7 days). All patients underwent minimally invasive reduction using the double reverse traction reducer. Surgical duration, intraoperative blood loss, and hospitalization time were recorded. Functional outcomes were assessed at last follow-up using the Hospital for Special Surgery (HSS) knee score and range of motion (ROM), while fracture reduction quality was evaluated using the Rasmussen radiological score. RESULTS: All 4 patients successfully completed the procedure without conversion to open reduction. The total mean operation time was 80.25 minutes (range, 73-86 minutes), with a mean total intraoperative blood loss of 132.5 mL (range, 100-150 mL). The mean hospitalization time was 13.5 days (range, 11-16 days). All incisions healed primarily without neurovascular complications. X-ray film at 1 day after operation confirmed satisfactory reduction and articular surface alignment. Follow-up time ranged from 12 to 26 months (mean, 17.0 months). Fractures achieved clinical union at an average of 13 weeks (range, 12-16 weeks). No complication, such as deep vein thrombosis, joint stiffness, post-traumatic arthritis, or implant failure, was observed. At last follow-up, the mean HSS score was 92.9 (range, 90-97), mean knee ROM was 128.1° (range, 115°-135°), and mean Rasmussen radiological score was 16.4 (range, 15-19), with 2 limbs rated as excellent and 6 as good. CONCLUSION The double reverse traction reducer facilitates minimally invasive treatment of bilateral tibial plateau fractures with advantages including minimal trauma, shorter surgical duration, precise reduction, and fewer complications, effectively promoting fracture healing and functional recovery of the knee joint.

Aluminum is a light metal which is rich in the earth's crust and widely used. Recently, the adverse health effects of environmental and occupational aluminum exposure on human have attracted more and more attention. Aluminum exposure has toxic effects on the central nervous system and is believed to be closely related to the development and progression of Alzheimer's disease. The neurotoxic mechanism of aluminum is complex, especially the role of regulated cell death (RCD) in aluminum-induced neuronal death remains to be further studied. RCD refers to all modes of cell death regulated by multiple intracellular signal transduction pathways under physiological and pathological conditions, including apoptosis, necroptosis, autophagy, pyroptosis, and ferroptosis. This review summarized the morphological characteristics and mechanisms of each RCD mode in the process of aluminum-induced neuronal death, and discussed the relationship and transformation between different RCD modes, providing a new scientific basis for future studies on the treatment and intervention of neurotoxicity induced by aluminum exposure.

Objective:To explore the effect of narrative nursing plan on patients with cancer fatalism at the initial stage of radiotherapy for nasopharyngeal carcinoma.Methods:Convenience sampling was used to select 126 patients with nasopharyngeal carcinoma who were admitted to the Third Ward of Radiotherapy, Affiliated Tumor Hospital of Guangxi Medical University from July 2019 to June 2020 with cancer fatalism at the initial stage of radiotherapy. Among them, 62 cases from July to December 2019 were set as the control group, and 64 cases from January to June 2020 were set as the observation group. Routine nursing intervention and narrative nursing intervention were given respectively, and before the intervention (the second day after admission), after 7 weeks of intervention, the Fatalism Scale and Center for Epidemiologic Studies-Depression scale scores of the two groups were compared.Results:Before the intervention, the cancer fatalism and depression scores of the two groups were at a high level and the difference was not statistically significant ( P>0.05); after the implementation of the narrative nursing intervention program, the cancer fatalism and depression scores of the observation group were (37.23±6.12), (9.42±1.36) points, lower than (47.78±9.14), (15.65±2.03) points of the control group. There was statistical significance ( t values were 7.698, 7.524, P<0.05). Conclusion:In the early stage of radiotherapy, patients with nasopharyngeal carcinoma have a strong concept of cancer fatalism, and narrative nursing intervention can effectively reduce their cancer fatalism and depression.

The central venous access device (CVAD) is widely used in infusion of intravenous high nutrient solution, chemotherapy drugs, rapid infusion, blood transfusion, etc. CVAD is left in the patient′s blood vessels for a long time, although it has certain advantages in intravenous therapy, but also risks associated with it. In the past 20 years, many studies have focused on the mechanism of CVAD on vascular injury, trying to explore its mechanism from a different perspective at the microscopic level of pathophysiology. This article will review the three aspects of acute damage to the blood vessel caused by CVAD catheterization and chronic changes caused by indwelling catheters, analysis of the causes of vascular injury caused by CVAD catheterization, and research on preventing vascular injury caused by CVAD catheterization, aiming at providing reference for clinical intravenous therapy.

Objective:To study the effect of Xuebijing on inflammatory response and prognosis in patients with septic shock.Methods:A prospective randomized controlled study was conducted. Eighty septic shock patients admitted to department of critical care medicine of the First Affiliated Hospital of Zhengzhou University from January to December in 2019 were enrolled. The enrolled patients were divided into Xuebijing group and control group by randomized number table method, with 40 cases in each group. Both groups were strictly followed the guidelines for the diagnosis and treatment of septic shock to take comprehensive treatment measures against sepsis. On this basis, Xuebijing group received intravenous 100 mL Xuebijing injection twice a day for 7 days. Baseline data of enrolled patients were recorded. The levels of interleukin-6 (IL-6), procalcitonin (PCT), C-reactive protein (CRP) and heparin binding protein (HBP) were measured before treatment and 3, 7 and 10 days after treatment. Mechanical ventilation time, the length of intensive care unit (ICU) stay, total hospitalization time and 28-day mortality were recorded. The differences of every indicator between the two groups were compared. Independent risk factors affecting patient prognosis were analyzed by binary Logistic regression.Results:① There was no significant difference in baseline data such as gender, age, infection site, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and sequential organ failure score (SOFA) between the two groups. ② The levels of serum inflammatory factors in both groups showed a decreasing trend after treatment. Compared with the control group, IL-6 and HBP in the Xuebijing group significantly decreased on day 7 [IL-6 (ng/L): 66.20 (16.34, 163.71) vs. 79.81 (23.95, 178.64), HBP (ng/L): 95.59 (45.23, 157.37) vs. 132.98 (73.90, 162.05), both P < 0.05]; on day 10, PCT, CRP, IL-6 and HBP significantly decreased [PCT (μg/L): 1.14 (0.20, 3.39) vs. 1.31 (0.68, 4.21), CRP (mg/L): 66.32 (19.46, 115.81) vs. 89.16 (20.52, 143.76), IL-6 (ng/L): 31.90 (13.23, 138.74) vs. 166.30 (42.75, 288.10), HBP (ng/L): 62.45 (29.17, 96.51) vs. 112.33 (58.70, 143.96), all P < 0.05]. ③ Compared with the control group, mechanical ventilation time and the length of ICU stay were significantly shortened and the total hospitalization expenses were significantly reduced in Xuebijing group [mechanical ventilation time (hours): 57.0 (0, 163.5) vs. 168.0 (24.0, 282.0), the length of ICU stay (days): 8.80±4.15 vs. 17.13±7.05, the total hospitalization expenses (ten thousand yuan): 14.55±7.31 vs. 20.01±9.86, all P < 0.05]. There was no significant difference in 28-day mortality and the total hospitalization time [28-day mortality: 37.5% vs. 35.0%, the total hospitalization time (days): 13.05±8.44 vs. 18.30±9.59, both P > 0.05]. ④ Patients were divided into death and survival groups according to the prognosis, and univariate analysis showed that white blood cell (WBC), neutrophil percentage (NEU%), CRP, lactic acid (Lac), APACHEⅡ score, IL-6, HBP were the factors influencing the prognosis of patients. The above indicators were further analyzed by Logistic regression, which showed that CRP, IL-6, and APACHE Ⅱ score were independent risk factors for prognosis [odds ratio ( OR) was 1.007, 1.828, 1.229, all P < 0.05]. Conclusions:Combined with Xuebijing to treat septic shock can reduce the body's inflammatory response to a certain extent, thereby reducing the time of mechanical ventilation, shortening the stay of ICU and reducing the total cost of hospitalization. But it cannot reduce the 28-day mortality of patients with septic shock.

Objective:To determine the law of dose variation in nasopharyngeal carcinoma patients treated with helical tomotherapy by observing the difference between the actual and planned doses of targets and at-risk organs in these patients. Methods:Ten naso-pharyngeal carcinoma patients were treated with helical tomotherapy. Each single dose distribution and the corresponding computed tomography (CT) images were transmitted to the commercial software MIMvista 6.50, which was used to perform deformable image registration on the CT images. The sum of the actual dose was then obtained by accumulating the single doses. The image-guided actu-al dose was denoted as Plan 2, and the initial plan was called Plan 1. The dose-volume histogram of the dose distribution of targets and at-risk organs in Plans 1 and 2 were compared. Results:The D98 and D95 doses of the planning gross target volume (PGTV) in Plan 2 were significantly lower than those in Plan 1. Compared with Plan 1, the Dmean and D50 doses of double parotids in Plan 2 were higher by 42.23%and 63.82%(P<0.001, P=0.001) on average, respectively, for the left parotid, as well as by 38.64%and 66.76%(P=0.002, 0.004), respectively, for the right parotid. The D2 dose of spinal cord in Plan 2 was significantly higher than that in Plan 1. The doses were higher by 16.49%on average (P=0.026). Conclusion:To achieve precise and individually adaptive radiotherapy, correcting the error between anatomy and placement during tomotherapy for nasopharyngeal carcinoma patients is necessary.
