60 patients with pathologically diagnosed erosive lichen planus of bilateral buccal mucosa were included.The lesion on one side was treated by local application of triamcinolone acetonide dental paste(test group),the lesion on the other side without treatment was used in the control group.7,1 4,21 and 28 d after treatment the pain level and the lesion situation scores in the test group decreased significantly (P <0.001 ),and lower than those in the control group at the same time point(P <0.05).No adverse reaction was found in the 2 groups. Triamcinolone Acetonide Dental Paste is effective in the treatment of erosive oral lichen planus.

The mortality rate of septic shock in children is high，and the number of cases has been increasing year by year.In recent years，the number of deaths has decreased with the development of medical technology.With the increasing number of surviving children with septic shock，the prognosis regarding these patients is gaining more attention of PICU physicians than before.The long-term sequelae of patients with septic shock，which often leads to multiple organ dysfunction and complications，severely affects the quality of children life after discharge from the hospital.Notably，the meaningful outcomes mainly include physical，mental，emotional，and social functioning.Currently，few studies focusing on quality of life in children surviving from septic shock have been reported in China.Herein，this review summarized the progress of research on the long-term prognosis of patients with septic shock.

Objective:To investigate the effects of early percutaneous coronary intervention (PCI) on myocardial perfusion and left ventricular function in patients with acute ST-segment elevation myocardial infarction (STEMI) after thrombolysis.Methods:A total of 108 patients with STEMI treated in the Second Hospital of Hebei Medical University from January 2020 to December 2022 were divided into early PCI following thrombolysis group ( n=65) and primary PCI (pPCI) group ( n=43). The general clinical data, and the parameters of routine echocardiography at 1 day after PCI and before discharge were compared between the two groups. Myocardial contrast echocardiography (MCE) was used to evaluate myocardial perfusion at 1 day after PCI and before discharge. Results:There were no significant differences in general clinical data between the early PCI following thrombolysis group and the pPCI group (all P>0.05). The left ventricular ejection fraction (LVEF) in the early PCI following thrombolysis group and pPCI group before discharge was significantly higher than that on the 1st day after PCI(both P<0.05). The difference of LVEF was significant between the early PCI following thrombolysis group and the pPCI group before discharge and 1 day after PCI ( P<0.05). Compared with 1 day after PCI, the global longitudinal strain (LVGLS) of left ventricle increased in early PCI following thrombolysis group and pPCI group before discharge(both P<0.05). The difference of LVGLS between early PCI following thrombolysis group and pPCI group before discharge and 1 day after discharge was statistically significant( P<0.05). There were no significant differences in left ventricular end-diastolic diameter (LVEDD), left ventricular end-diastolic volume (LVEDV), left atrial volume (LAV), ratio of mitral early diastolic velocity to late diastolic velocity (E/A), mean early diastolic velocity of mitral annulus (Em) and E/Em 1 day after PCI and before discharge between early PCI following thrombolysis group and pPCI group (all P>0.05). MCE showed that the MCE score index of early PCI following thrombolysis group and pPCI group before discharge was significantly lower than that of 1 day after PCI(both P<0.001). Compared to the 1 day after PCI, the early PCI following thrombolysis group showed a significant increase in the proportion of normal microvascular perfusion (nMVP) and a decrease in the proportion of delayed microvascular perfusion (dMVP) and microvascular obstruction (MVO) before discharge (all P<0.05). In contrast, the pPCI group demonstrated a significant decrease in the proportion of both nMVP and dMVP before discharge compared to the first day after PCI (all P<0.05). However, the decrease in the proportion of MVO was not statistically significant ( P>0.05). Conclusions:Early PCI following thrombolysis and pPCI can enhance left ventricular systolic function and myocardial perfusion in patients with acute ST-elevation myocardial infarction. Early PCI following thrombolysis may offer additional advantages in improving left ventricular systolic function and myocardial perfusion.

Objective To explore the progress and prospect of preventive, predictive, personalized and participatory (4P) medicine in China in order to promote the ^“4P^” medicine and provide reference for the government and medical institutions to strengthen health management. Methods An in-depth analysis and review of the ^“4P^” medical service model was conducted through literature review. The prospect of the future development of the ^“4P^” medicine was discussed. Results In recent years, with the advancement of human health concepts and the completion of the genome project, the human healthcare model has been gradually shifting to the ^“4P^” medical service model, namely preventive-predictive-personalized-participatory integrated medicine. It can be seen that modern medical model has been in the process of continuous transformation, which is more human-oriented and emphasizes people^’s initiative. Conclusions With the widespread and understanding of the ^“4P^” medicine among healthcare workers, the value of the “4P” medicine in public health and clinical practice has been continuously proven.

BACKGROUND: T-cell immunoreceptor with immunoglobulin and immunoreceptor tyrosine-based inhibition motif domains (TIGIT), an inhibitory receptor expressed on T cells, plays a dysfunctional role in antiviral infection and antitumor activity. However, it is unknown whether TIGIT expression on T cells influences the immunological effects of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) inactivated vaccines. METHODS: Forty-five people living with HIV (PLWH) on antiretroviral therapy (ART) for more than two years and 31 healthy controls (HCs), all received a third dose of a SARS-CoV-2 inactivated vaccine, were enrolled in this study. The amounts, activation, proportion of cell subsets, and magnitude of the SARS-CoV-2-specific immune response of TIGIT + CD4 + and TIGIT + CD8 + T cells were investigated before the third dose but 6 months after the second vaccine dose (0W), 4 weeks (4W) and 12 weeks (12W) after the third dose. RESULTS: Compared to that in HCs, the frequency of TIGIT + CD8 + T cells in the peripheral blood of PLWH increased at 12W after the third dose of the inactivated vaccine, and the immune activation of TIGIT + CD8 + T cells also increased. A decrease in the ratio of both T naïve (T N ) and central memory (T CM ) cells among TIGIT + CD8 + T cells and an increase in the ratio of the effector memory (T EM ) subpopulation were observed at 12W in PLWH. Interestingly, particularly at 12W, a higher proportion of TIGIT + CD8 + T cells expressing CD137 and CD69 simultaneously was observed in HCs than in PLWH based on the activation-induced marker assay. Compared with 0W, SARS-CoV-2-specific TIGIT + CD8 + T-cell responses in PLWH were not enhanced at 12W but were enhanced in HCs. Additionally, at all time points, the SARS-CoV-2-specific responses of TIGIT + CD8 + T cells in PLWH were significantly weaker than those of TIGIT - CD8 + T cells. However, in HCs, the difference in the SARS-CoV-2-specific responses induced between TIGIT + CD8 + T cells and TIGIT - CD8 + T cells was insignificant at 4W and 12W, except at 0W. CONCLUSIONS TIGIT expression on CD8 + T cells may hinder the T-cell immune response to a booster dose of an inactivated SARS-CoV-2 vaccine, suggesting weakened resistance to SARS-CoV-2 infection, especially in PLWH. Furthermore, TIGIT may be used as a potential target to increase the production of SARS-CoV-2-specific CD8 + T cells, thereby enhancing the effectiveness of vaccination.
