A bladder cancer patient underwent intravesical Bacillus Calmette-Guérin (BCG) instillation in Xiamen Branch, Zhongshan Hospital, Fudan University in April 2023. Following 8 instillations the patient presented with fever, cough and dyspnea, and was diagnosed as interstitial pneumonia (IP). Symptoms resolved after anti-tuberculosis and methylprednisolone treatment, with subsequent successful discharge. Using the keywords ′Bacillus Calmette-Guérin, ′ ′intravesical instillation, ′ ′pneumonia, ′ Wanfang Data, China National Knowledge Infrastructure(CNKI), Weipu(VIP), and PubMed databases were searched for relevant literature published between January 2014 and June 2024, and 20 cases of BCG instillation-induced pneumonia were retrieved, including 10 IP cases and 10 miliary pneumonia cases. Among 10 IP cases, 7 received corticosteroids combined with anti-tuberculosis therapy. Two cases unresponsive to combination therapy resulted in mortality, while others showed therapeutic efficacy. Miliary pneumonia demonstrated better prognosis, with 6 cases achieving complete remission through anti-tuberculosis monotherapy. The results indicate that severe BCG-related pneumonia generally necessitates combined anti-tuberculosis and corticosteroid therapy.

When conducting extravehicular activities under low-gravity conditions like on the moon,the weight of the spacesuit is one of the loads that human body has to bear.The centroid position of the spacesuit will affect the motion control of the human-spacesuit system.In order to reveal the influence of the centroid position of the lunar spacesuit on human motion under lunar-gravity,a suspended 1/6 gravity simulation system was used for the experiment.When subjects were under different load centroids which include front and back on sagittal plane,left and right on coronal plane,up and down on cross-section plane,near to coordinate origin,the postures and plantar pressures of subjects during three typical movements:standing,single-knee standing and walking were captured.Inverse dynamics solution is adopted to analyze the joint torques of human body in above conditions.Combined with the subjective evaluation,the appropriate load centroid area was analyzed by comparative.The experiment shows that,human is non-sensitive to the up and down change of load centroid,the after is back change,the front and right load centroid are the mostly avoided.The results obtained by this study will provide a reference for the layout design of the lunar spacesuit.

Liver transplantation is a crucial treatment for end-stage liver disease,yet its complexity continues to limit clinical application.With the development of the internet and big data,artificial intelligence(AI)technologies have gradually expanded their use in liver transplantation surgery,covering donor liver evaluation,organ allocation,robot-assisted surgery,and postoperative management,demonstrating significant advantages.However,the application of AI also raises a series of ethical issues,notably fairness in resource allocation,conflicts between technical limitations and the principle of non-maleficence,ambiguous responsibility attribution,patient privacy security,and informed consent.This article systematically reviews the current applications of AI in liver transplantation surgery and the related ethical challenges,aiming to provide a reference for its rational use and sustainable development.

Objective To explore the mechanism of Shanggan granules in suppressing pulmonary inflammation in mice infected with H1N1 influenza virus.Methods A mouse model of pulmonary influenza virus infection was established by nasal inoculation with H1N1 influenza virus.Mice were divided into a normal control group,model group,positive control group,and low-,medium-,and high-dose Shanggan granules groups.Mice were treated for 7 days and then sacrificed,and the body weight and lung wet weight were measured.Pathological changes in the lung tissues were detected by hematoxylin/eosin(HE)staining.Tumor necrosis factor-α(TNF-α),interleukin(IL)-6,IL-8,and transforming growth factor-β(TGF-β)levels in lung tissues were detected by enzyme-linked immunosorbent assay,and superoxide dismutase(SOD),glutathione peroxidase(GSH-Px),and malondialdehyde(MDA)were detected using appropriate kits.Toll-like receptor 4(TLR4)/nuclear factor-κB(NF-κB)inflammatory signaling pathways were detected by real-time polymerase chain reaction,and TANK-binding kinase 1(TBK1)/interferon regulatory factor(IRF)signaling pathway proteins were detected by Western blot.Results Both Shanggan granules and oseltamivir phosphate reduced the lung wet weight(P＜0.05,P＜0.001)in mice infected with influenza virus H1N1 compared with the model group,decreased the infiltration of inflammatory cells in lung tissue,reduced levels of the inflammatory factors TNF-α,IL-6,IL-8,and TGF-β(P＜0.05,P＜0.01,P＜0.001),decreased levels of SOD and GSH-Px in lung tissue(P＜0.05,P＜0.01),and increased MDA levels(P＜0.05,P＜0.01).Shanggan granules and oseltamivir phosphate also reduced TLR4,MyD88,and p38 mRNA levels(P＜0.05,P＜0.01)and expression of TBK1/IRF3/7/NF-κB signaling pathway proteins(P＜0.05,P＜0.01,P＜0.001).Conclusions Shanggan granules may effectively reduce lung injury,lung inflammation,and oxidative stress,via a mechanism related to the down-regulation of TLR4/NF-κB inflammatory signaling pathways.

Objective:To investigate the efficacy of toric intraocular lens (IOL) combined with capsular tension rings (CTR) in the treatment of high myopia complicated by corneal astigmatism and cataract and its effects on visual acuity.Methods:A retrospective study was conducted on 80 eyes of 80 patients with high myopia complicated by corneal astigmatism and cataract who received treatment at Baoji People's Hospital from December 2021 to December 2023. Based on the treatment methods, the patients were divided into two groups. The study group was treated with toric IOL combined with CTR, while the control group was treated with toric IOL only. The best corrected visual acuity, corneal astigmatism, visual quality, the degree of intraocular lens rotation, and the incidence of postoperative complications were compared between the two groups before and after surgery.Results:After surgery, the best corrected visual acuity and corneal astigmatism in the study group were significantly better than those in the control group [(0.18 ± 0.24) LogMAR vs. (0.23 ± 0.16) LogMAR, t = 4.05, P < 0.001; (0.73 ± 0.22) D vs. (0.45 ± 0.26) D, t = 6.79, P = 0.001]. At 1 month post-surgery, the visual quality scores in the study group were significantly higher than those in the control group ( t = 5.36, 6.35, 7.14, 4.25, all P < 0.05). At 1 week, 1 month, 3 months, and 6 months after surgery, the degrees of intraocular lens rotation in the study group were less than those in the control group ( t = 5.59, 2.70, 4.22, 6.10, all P < 0.05). At 6 months post-surgery, the incidence of complications in the study group was lower than that in the control group [20.00% (8/40) vs. 45.00% (18/40), χ2 = 5.70, P = 0.017]. Conclusions:Toric IOL combined with CTR treatment can effectively improve the visual function in patients with high myopia complicated by corneal astigmatism and cataract. This approach reduces the incidence of postoperative complications and minimizes astigmatism, proving to be both safe and effective.

Objective:To explore the effect of persuasion system-based health intervention in orthodontic patients treated with clear aligners.Methods:From January 2022 to December 2023, convenience sampling was used to select patients treated with clear aligners at the Department of Orthodontics in Affiliated Stomatological Hospital of Nanjing Medical University as participants. Patients admitted from January to December 2022 were included in the control group ( n=60), and those admitted from January to December 2023 were included in the observation group ( n=59). The control group received health guidance based on the theory of knowledge, attitude, and practice. Based on the control group, the observation group added health intervention with the assistance of a persuasion system. After one year of intervention, the oral care self-efficacy, enamel demineralization, periodontal health index (gingival index, plaque index, sulcus bleeding index, probing depth), and restart rate of both groups were evaluated. Results:After the intervention, the scores of the Self-efficacy Scale for Self-care in the observation group were higher than those in the control group, and the difference was statistically significant [ (71.03±1.97) vs. (57.82±2.58), P<0.01]. The enamel demineralization rate, periodontal health index (plaque index, gingival index, sulcus bleeding index, probing depth) score, and restart rate in observation group were all lower than those in control group ( P<0.05) . Conclusions:Persuasion system system-based health intervention can improve the oral care self-efficacy of orthodontic patients treated with clear aligners, alleviate oral health issues during clear aligners, and reduce the restart rate of clear aligner patients.
