Objective:To investigate the application value of optical coherence tomography (OCT) and intravascular ultrasound (IVUS) in evaluating flow diverter (FD) apposition and endothelialization in aneurysm animal models, and analyze the effect of incomplete stent apposition (ISA) on aneurysm lumen healing and stent endothelialization.Methods:Lateral common carotid artery aneurysm models in swines were established by surgical method and then FD was implanted. Immediately after surgery, OCT and IVUS were used to evaluate the locations and degrees of ISA, and difference between these 2 methods in evaluating FD apposition was compared. DSA was performed at 12 weeks after surgery to evaluate the aneurysm occlusion (Kamran grading) and stent patency. OCT and IVUS were used again to observe the stent endothelial situation; by comparing with histopathologic results, effect of ISA on aneurysm healing and stent endothelialization was analyzed.Results:Lateral common carotid artery aneurysm models in 6 swines were established, and 6 Tubridge FDs were successfully implanted. Compared with IVUS (3 stents, 4 locus), OCT could detect more ISA (6 stents, 14 locus); and the vascular diameter change area (7 locus), aneurysm neck area (4 locus) and the head and tail of FD (3 locus) were the main sites of FD malapposition; average distance between stent wire and vessel wall was (560.14±101.48) μm. At 12 weeks after surgery, DSA showed that 1 patient had a little residual contrast agent at the aneurysm neck (Kamran grading 3), and the remaining 5 had complete aneurysm occlusion (Kamran grading 4). One FD had moderate lumen stenosis, and the other 5 FDs had lumen patency. OCT indicated mostly disappeared acute ISA; ISA proportion decreased to 21.4 % (3/14), including 2 in the aneurysm neck and 1 in the partial stent. Histopathological results showed bare stent woven silk, without obvious endothelial coverage; in one FD with luminal stenosis, intimal hyperplasia was mainly composed of vascular smooth muscle cells.Conclusion:In carotid artery aneurysm model with FD implantation, OCT can detect more ISA than IVUS; most acute ISA have good outcome at 12 th week of follow-up, while severe ISA can cause delayed FD endothelialization and delayed aneurysm occlusion.

Objective To explore the clinical efficacy of low molecular weight heparin combined with insulin in the treatment of hyper-triglyceridemic-acute pancreatitis(HTG-AP).Methods A total of 106 patients diagnosed with HTG-AP who were admitted to the department of gastroenterology of Huaibei People's Hospital from May 2022 to July 2023 were selected as the research objects.According to the random number table method,the low-molecular heparin group(35 cases,received a 5 000 U subcutaneous injection low-molecular heparin once every 12 hours for 6 days),the insulin group(35 cases,received intravenous insulin pumping at a rate of 2 U/h,with careful monitoring of the patient's random blood glucose levels to prevent hypoglycemia),and the combination therapy group(36 cases,received both low-molecular heparin and insulin).Before treatment and at 1,2,and 6 days after treatment,the difference of serum triacylglycerol(TG),total cholesterol(TC),blood amylase,inflammatory factors[C-reactive protein(CRP),interleukin-6(IL-6)],calcium ions,and creatinine levels among the three groups were compared.The modified computed tomography severity index(MCTSI)scores,acute physiology and chronic health evaluationⅡ(APACHEⅡ),hospital length of stay,and hospital costs before and after 6 days of treatment were observed.Results After treatment,the TC of all three groups significantly decreased compared to before treatment(P<0.05),but there was no significant difference among the three groups.The calcium ion levels of the three groups did not show a statistically significant difference before and after treatment.After 6 days of treatment,the creatinine levels of the three groups significantly decreased compared to before treatment,but there was no significant difference among the three groups.After 2 days of treatment,serum TG levels were significantly lower in the combination therapy group and insulin group compared to the low-molecular heparin group(mmol/L:4.6±1.7,4.4±1.8 vs.5.6±2.0,both P<0.05).However,there was no statistically significant difference between the combination therapy group and the insulin group.After 6 days of treatment,the combination therapy group showed significantly lower levels of serum TG,blood amylase,CRP,and IL-6 compared to the insulin group and the low-molecular heparin group[TG(mmol/L):2.8±1.9 vs.4.3±1.9,5.0±2.2,blood amylase(U/L):36.0(32.0,45.0)vs.59.0(43.0,71.0),52.0(45.0,64.0),CRP(mg/L):12.9(8.8,29.7)vs.35.3(21.7,50.3),31.4(23.0,45.1),IL-6(ng/L):15.4(9.8,23.5)vs.25.6(16.4,51.5),32.9(14.7,41.4),all P<0.05].After 6 days of treatment,the APACHEⅡscores of all three groups decreased significantly(all P<0.05).The MCTSI scores of the insulin group and the combined treatment group also decreased significantly compared to before treatment.Furthermore,the MCTSI and APACHEⅡscores of the combination therapy group were significantly lower than those of the low-molecular heparin group and the insulin group(MCTSI score:2.3±0.7 vs.3.3±1.7,2.9±1.3,APACHEⅡscore:1.3±1.2 vs.2.5±2.4,2.6±2.5,all P<0.05).The combination therapy group had significantly lower length of hospital stay and treatment cost compared to the low molecular heparin and insulin groups[length of hospital stay(days):6.9±1.6 vs.8.8±3.4,8.5±2.8,and cost of treatment(yuan):6 040.5(5 239.4,7 105.9)vs.6 696.4(5 791.5,11 026.2),6 918.5(6 087.9,10 080.8),all P<0.05].Conclusions The combination of low-molecular heparin and insulin treatment can significantly reduce serum TG and inflammatory factor levels,as well as the severity and duration of the disease.This approach can also reduce the cost of treatment.Therefore,it is worth promoting and applying in clinical settings.

Abstract: Objective　To explore the effect of Yiaikang on the expression of sterile alpha motif and histidine-aspartic acid domain-containing protein 1(SAMHD1), a host restriction factor, and interferon levels in peripheral blood of HIV-infected patients with lung-spleen Qi deficiency syndrome. This aims to provide insights into the mechanism of YiaiKang in the treatment of AIDS. Methods According to the diagnostic criteria of Western medicine for AIDS and traditional Chinese medicine for lung-spleen Qi deficiency syndrome, 22 cases of HIV patients with lung and spleen Qi deficiency syndrome were enrolled in the study from the First Affiliated Hospital of Henan University of TCM between September 2020 and May 2021, and 20 healthy people in the area were taken as control. The patients with lung and spleen Qi deficiency syndrome were treated with Yiaikang for 6 months. T lymphocyte subpopulation changes and expression level of SAMHD1 protein in T cells were detected by flow cytometry. SAMHD1 mRNA expression in peripheral blood mononuclear cells (PBMCs) was detected by fluorescence quantitative PCR. The levels of IFN-α, IFN-β, IFN-γ, and IL-2 in plasma were detected by enzyme-linked immunosorbent assay (ELISA). The changes of SAMHD1 and interferon in peripheral blood of HIV patients with lung and spleen Qi deficiency syndrome were analyzed to explore the intervention effect of Yiaikang. Results Compared with healthy people, HIV patients with lung and spleen Qi deficiency syndrome exhibited a reduction in the CD4 + T lymphocyte count and CD4/CD8 ratio (Z=-3.526, P<0.001; Z=-0.881, P<0.001). There was an increase in the expression of SAMHD1 protein in T lymphocytes (SAMHD1 MFI/CD4: Z=-3.425, P=0.001; SAMHD1 MFI/CD8: Z=-2.153, P=0.031) and an increase in the expression of SAMHD1 gene in PBMCs (Z=-3.828, P<0.001). Yiaikang treatment significantly increased the CD4 + T cell count and CD4/CD8 ratio (Z=-2.711, P=0.007; Z=-2.062, P=0.039), decreased the expression of SAMHD1 mRNA (Z=-2.581, P=0.010), and decreased the levels of IFN-α and IFN-γ (Z=-1.985, P=0.047; Z=-2.744, P=0.006). Conclusions Patients with lung-spleen Qi deficiency syndrome have reduced numbers of CD4 + T cells and CD4/CD8 ration, with increased expression of SAMHD1 and interferon factors. Yiaikang treatment can increase the number of CD4 + T cells and CD4/CD8 ratio and reduce the expression of SAMHD1 and interferon factor, thereby improving the immune imbalance caused by HIV infection.

Objective: To observe the characteristics of the evolution of liver indexes in patients with relapsed/refractory multiple myeloma (RRMM) treated with CAR-T-cells based on BCMA. Methods: Retrospective analysis was performed of patients with RRMM who received an infusion of anti-BCMA CAR-T-cells and anti-BCMA combined with anti-CD19 CAR-T-cells at our center between June 1, 2019, and February 28, 2023. Clinical data were collected to observe the characteristics of changes in liver indexes such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), and direct bilirubin (DBIL) in patients, and its relationship with cytokine-release syndrome (CRS) . Results: Ninety-two patients were included in the analysis, including 41 patients (44.6%) in the group receiving a single infusion of anti-BCMA CAR-T-cells, and 51 patients (55.4%) in the group receiving an infusion of anti-BCMA combined with anti-CD19 CAR-T-cells. After infusing CAR-T-cells, 31 patients (33.7%) experienced changes in liver indexes at or above grade 2, which included 20 patients (21.7%) with changes in one index, five patients (5.4%) with changes in two indexes, and six patients (6.5%) with changes in three or more indexes. The median time of peak values of ALT and AST were d17 and d14, respectively, and the median duration of exceeding grade 2 was 5.0 and 3.5 days, respectively. The median time of peak values of TBIL and DBIL was on d19 and d21, respectively, and the median duration of exceeding grade 2 was 4.0 days, respectively. The median time of onset of CRS was d8, and the peak time of fever was d9. The ALT, AST, and TBIL of patients with CRS were higher than those of patients without CRS (P=0.011, 0.002, and 0.015, respectively). CRS is an independent factor that affects ALT and TBIL levels (OR=19.668, 95% CI 18.959-20.173, P=0.001). The evolution of liver indexes can be reversed through anti-CRS and liver-protection treatments, and no patient died of liver injury. Conclusions: In BCMA-based CAR-T-cell therapy for RRMM, CRS is an important factor causing the evolution of liver indexes. The evolution of liver indexes after CAR-T-cell infusion is transient and reversible after treatment.

Medicinal plants or Chinese materia medica (CMM) are now attracting worldwide attention as they have increasingly prominent advantages over chemical drugs in disease treatment and healthcare. Since the 1990s, World Health Organization (WHO) and International Organization for Standardization established the Technical Committee of Traditional Chinese Medicine (ISO/TC 249) have carried out the development of quality standards on medicinal plants or CMMs respectively, and a considerable number of monographs and international standards have been published. Since the two international organizations adhere to different principles, the standards they develop naturally have different emphasis. Driven by market demand and international trade, ISO mainly takes quality, efficacy and safety into consideration when developing standards, while WHO pays more attention to clinical practice, quality control and medication guidance. Up to now, there is a lack of comparative analysis on the records, background, principles, basic content, and main requirements of quality standards on medicinal plants or CMMs respectively published by WHO and ISO. Therefore, based on international standards of CMM developed by ISO/TC 249 platform and WHO Monographs on Selected Medicinal Plants, this paper systematically compares the purposes, selected principles, standard-developing process, basic content, and main quality requirements to summarize their similarities and differences, and find their merits, aiming to serve as a reference to the development of international standards for CMMs that helps them go global.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

In 2006, 2014 and 2020, the positive rates of HBsAg in 560, 384 and 402 children aged 1 to 14 years were 4.5%, 2.6% and 2.5%, respectively, with no statistically significant differences (P>0.05). The positive rate of anti-HBs was highest in 2014 (57.8%) and lowest in 2006 (34.1%) (P<0.05). The positive rate of anti-HBc was highest in 2006 (15.7%), and decreased in 2014 (7.8%) and 2020 (5.7%) (P<0.001). The timely rate of the first dose of hepatitis B vaccine for children in Lhasa in 2006, 2014 and 2020 was 7.7% (43/560), 50.3% (193/384) and 94.8% (381/402), respectively. The overall vaccination rates were 15.4% (86/560), 35.2% (135/384) and 96.0% (386/402), respectively, showing a trend of gradual increases (χtrend values were 718.63 and 589.59, both P values<0.001).
