ObjectiveTo investigate the effect of shikosin (SHI) on psoriasis (PSO) and explore the underlying mechanism via the cyclic guanosine monophosphate-adenosine monophosphate synthase (cGAS)/stimulator of interferon genes (STING) signaling pathway. MethodHaCaT cells were classified into normal culture(Control), a mixture of five proinflammatory cytokines(M5), low-, medium-, and high-dose SHI (L-SHI, M-SHI, and H-SHI, respectively), and SHI+ADU-S100 groups. The cells in the M5 group were stimulated with 10 μg·L-1 interleukin (IL)-1α, IL-17, IL-22, tumor necrosis factor (TNF)-α, and oncostatin M (OSM) for 48 h. The cells in the L-SHI, M-SHI, and H-SHI groups were treated with 0.1, 1, 10 μmol·L-1 SHI, respectively, on the basis of the treatment in the M5 group. The cells in the SHI+ADU-S100 group were treated with 10 μmol·L-1 STING activator ADU-S100 on the basis of the treatment in the H-SHI group. The methyl thiazolyl tetrazolium (MTT) assay and colony formation assay were employed to examine the effect of SHI on the proliferation of HaCaT cells. The wound healing assay was employed to examine the effect of SHI on the migration of HaCaT cells. Flow cytometry was employed to detect the effect of SHI on the apoptosis of HaCaT cells. Enzyme-linked immunosorbent assay was employed to measure the levels of IL-1β, IL-6, IL-15, IL-23, and interferon-γ (IFN-γ) in HaCaT cells. Western blot was employed to determine the protein levels of cGAS and STING in HaCaT cells. ResultCompared with Control group, the M5 group showed decreased survival rate, colony formation, and would healing rate of HaCaT cells, increased apoptosis rate, elevated levels of IL-1β, IL-6, IL-15, IL-23, and IFN-γ, and up-regulated protein levels of cGAS and STING (P<0.01). Compared with the M5 group, the L-SHI, M-SHI, and H-SHI groups showed increased survival rate, cell colony formation, and wound healing rate, decreased apoptosis rate, lowered levels of IL-1β, IL-6, IL-15, IL-23, and IFN-γ, and down-regulated protein levels of cGAS and STING (P<0.01). Compared with the H-SHI group, the SHI+ADU-S100 group showed decreased survival rate, cell colony formation, and wound healing rate, increased apoptosis rate, risen levels of IL-1β, IL-6, IL-15, IL-23, and IFN-γ, and up-regulated protein levels of cGAS and STING (P<0.01). ConclusionSHI can inhibit the inflammation in the cell model of PSO by inhibiting the cGAS/STING signaling pathway.

Objective To examine the application effectiveness of dual 8F ultrafine pigtail drainage tubes versus a single 28F large-bore chest tube in single-port thoracoscopic lobectomy/segmentectomy. Methods Clinical data of patients who underwent single-port video-assisted thoracoscopic lobectomy/segmentectomy within our medical group from January 2020 to August 2023 were retrospectively analyzed. They were categorized into two groups based on postoperative drainage methods: a dual 8F ultrafine pigtail tubes group and a single 28F large-bore chest tube group. Comparative analysis was performed on perioperative data for the two groups of patients. Results The dual 8F ultrafine pigtail tubes group comprised of 68 patients, with 41 females and 27 males, and an average age of (54.72±13.34) years, while the single 28F large-bore chest tube group comprised of 80 patients, with 40 females and 40 males, and an average age of (57.60±11.04) years. There were statistical differences between the two groups in terms of postoperative drainage volume on day 1, day 2, and day 3, total postoperative drainage volume, postoperative tube placement time, postoperative pain score at 48 hours, maximum postoperative pain score, postoperative hospital stay, postoperative complications related to drainage tubes, and emergency use of pain-relieving medication after surgery (P<0.05). Conclusion After single-port thoracoscopic lobectomy/segmentectomy, the application of dual ultrafine 8F pigtail drainage tubes can lead to a reduction in postoperative drainage volume and shorten the duration of postoperative drainage tube placement and hospital stay, thereby decreasing postoperative pain and the frequency of emergency pain-relieving medication. Moreover, it lowers the incidence of drainage tube-related complications. In alignment with current enhanced recovery after surgery principles, this approach is advantageous for postoperative recovery.

Objective:To analyze the clinical characteristics in patients with persistent positive pharyngeal swab of 2019 novel coronavirus Omicron variant and results of nucleic acid testing of anal swabs to provide basis for prevention and control measures.Methods:This study included 93 patients whose pharyngeal swab nucleic acid test were persistent positive and admitted to the ward of Daping Hospital in the National Exhibition and Convention Center (Shanghai) Makeshift Hospital from May 1 to May 24, 2022. The gender, age, underlying diseases, vaccination status, clinical symptoms, interval between infection onset and anal sampling, length of hospital stay, the nucleic acid test result of pharyngeal swabs and anal swabs and the time turning negative were collected and analyzed.Results:The age of 93 patients ranged from 8 to 72 years old with a median of (46.0±16.0) years old. Among them, 30 cases (32.3%) were male and 63 cases (67.7%) were female. Sixty-five patients (69.9%) received 2-3 shots of vaccine, 2 patients (2.1%) received 1 shot, and 26 patients (28.0%) did not receive any vaccination. Twenty patients (21.5%) had underlying diseases, of which hypertension (13 cases, 14.0%) and type 2 diabetes mellitus (6 cases, 6.5%) were the most common. Twenty-four patients (25.8%) had asymptomatic infection and the rest (69 cases, 74.2%) had mild symptoms. Cough (50 cases, 53.8%) and sore throat (28 cases, 30.1%) were the most common clinical manifestations of the upper respiratory tract in these patients. Only 6 patients (6.5%) had gastrointestinal symptoms (including diarrhea in 5 patients and diarrhea with vomiting in 1 patient). Pharyngeal and anal swabs were collected simultaneously from all 93 patients at 8-16th days [(11.55±2.27) days] after 2019 novel coronavirus Omicron variant infection. The pharyngeal swabs were positive in 79 patients (85.0%) and the anal swabs were positive in 5 patients (5.4%). The time of pharyngeal swabs turning negative was (14.7±2.9) days, and that of anal swab turning positive was (14.2±1.9) days. The median length of hospital stay was (16.7±2.9) days.Conclusions:In patients with persistent positive nucleic acid of the 2019 novel coronavirus Omicron variant, there were more mild infection than asymptomatic. The upper respiratory tract symptoms such as cough and sore throat were the most. The likelihood of transmission of 2019 novel coronavirus Omicron variant through the digestive tract may be low. The correlation between gastrointestinal symptoms and 2019 novel coronavirus Omicron variant RNA in the digestive tract is uncertain.
