Professor LIU Qingguo's academic thoughts and clinical experience in treating pediatric tic disorders with scalp fire needling is introduced. Professor LIU believes that the core pathogenesis of this disease lies in "wind stirring and qi disorder, leading to the spirit failing to govern the body". Therefore, treatment should focus on "regulating the spirit to stabilize the form and extinguishing wind to stop movement". Clinically, the main acupoints include Shenting (GV24), Benshen (GB13), Xinhui (GV22), Baihui (GV20), Sishencong (EX-HN1), Fengchi (GB20), and Fengfu (GV16), which are rapidly punctured with fine fire needles, leading to significant therapeutic efficacy.

Objective:To analyze plaque characteristics of non-culprit coronary lesions with cholesterol crystals in patients with acute myocardial infarction(AMI) by using optical coherence tomography(OCT). We also investigated the potential association between cholesterol crystals with plaque rupture and healed plaque at non-culprit segment.Methods:This study was a retrospective cohort study. Between January 2017 and December 2017, patients with AMI who underwent 3-vessel OCT imaging were included in this study. Patients were divided into two groups according to the presence or absence of cholesterol crystals at the non-culprit lesions. All patients underwent coronary angiography and OCT examination, and non-culprit plaque characteristics were compared between the two groups. The generalized estimating equation log-binomial multirariate regression model was used to assess the relationship between non-culprit lesions with cholesterol crystals and plaque rupture and plaque healing. The follow-up data collection ended in October 2023. Kaplan-Meier survival curves were plotted, and log-rank tests were used to compare the cumulative incidence of major adverse cardiovascular events between the two groups.Results:A total of 173 AMI patients were included (aged (56.8±11.6) years; 124 men (71.7%)). Among 710 non-culprit lesions identified by OCT, there were 102 (14.4%) in cholesterol crystals group and 608 (85.6%) in non-cholesterol crystals group. Compared with non-culprit lesions without cholesterol crystals, those with cholesterol crystals had smaller minimum lumen diameter, severer diameter stenosis, and longer lesion length (all P<0.01). The prevalence of plaque rupture (17.6% (18/102) vs. 4.9% (30/608), P=0.001) and thin-cap fibroatheroma (31.4% (32/102) vs. 11.5% (70/608), P<0.01) was higher in the cholesterol crystals groups than in the non-cholesterol crystals group. In addition, vulnerable plaque characteristics such as (44.1% (45/102) vs. 25.8% (157/608), P<0.01), macrophages were more frequently observed in non-culprit lesions with cholesterol crystals. The generalized estimating equation log-binomial multivariate regression analyses showed that non-culprit cholesterol crystals were positively correlated with healed plaque ( OR=1.583, 95% CI: 1.004-2.495, P=0.048). Conversely, cholesterol crystals were not associated with plaque rupture ( OR=1.632, 95% CI: 0.745-3.576, P=0.221). The follow-up time was 2 142 (1 880, 2 198) days. Non-culprit cholesterol crystals were not related to the major adverse cardiovascular events in patients with AMI (log-rank P=0.558). Conclusions:Among AMI patients, non-culprit lesions with cholesterol crystals presented with severer luminal stenosis and increased plaque vulnerability. The presence of non-culprit cholesterol crystals was associated with rather than plaque rupture.

Objective:To summarise and analyse the experience in the diagnosis and management of abdominal aortic endograft infection in recent years.Methods:Retrospectively summarised and analysed the general data, clinical presentation, laboratory and imaging findings, causative organisms and treatment choices of 14 patients with abdominal aortic endograft infection treated in Beijing Friendship Hospital, Capital Medical University, from January 2018 to June 2024, and analysed the prognosis of the patients and the risk factors associated with prognosis.Results:Positive bacterial cultures were 10 out of 14 patients. One non-operatively treated patient died of infectious toxic shock. Thirteen surgically treated patients underwent axillary-bifemoral artery bypass, removal of the infected stent, and closure of the aortic stump. Four of the 13 cases had combined aortoenteric fistula, 3 cases underwent one-stage enterocutaneous fistula repair, 1 case only fistula drainage, 3 cases of gastrojejunal anastomosis, all of them underwent gastric or jejunal nutrient tube implantation. Two of the 13 patients had combined the infection foci spread to the renal artery openings. To save the kidney, intraoperative left kidney autologous renal transplantation was performed in 1 case, and autologous saphenous vein reconstruction from celiac trunk artery-left renal artery and superior mesenteric artery-right renal artery was performed in the other case. All 14 patients were retrospectively summarised and followed up in August 2024, with 5 deaths in the early postoperative period (< 3 months), 3 deaths in the mid- to long-term period (≥3 months), and 5 survivors, with a median follow-up time of 2 years (1-5 years) for surviving patients. Among the 13 operated patients, 4 cases were combined with aortoenteric fistula, and 3 cases died in the early postoperative period; 4 cases of abdominal aortic infection foci involving renal artery openings, 2 cases of early postoperative death; 4 cases with pleural effusion, 4 cases died in the early postoperative period; 2 cases of combined creatinine elevation, 2 cases of early postoperative death; 2 cases of postoperative infection of artificial blood vessels.Conclusions:Abdominal aortic endograft infection are aggressive. The risk of early death is increased in patients who are elderly, in poor general condition, with aortoenteric fistula or with pre-existing cardiac, pulmonary, hepatic and renal insufficiency, but surgery based on adequate anti-infective therapy remains an effective means of saving the patient′s life.

ObjectiveTo observe the effects of Cuscutae Semen on the learning and memory ability， N6-methyladenosine （m⁶A）-related modification enzymes and total m⁶A level in hippocampus of the offspring of fear-damaged pregnant rats. MethodForty-five pregnant rats were randomly divided into blank group， model group and Cuscutae Semen group. From the 1^st day to the 19^th day of pregnancy， rats in the model group and the Cuscutae Semen group were induced by observing electric shock of other rats. The Cuscutae Semen group was treated with 5 g·kg^-1·d^-1 Cuscutae Semen decoction （ig）， while the other two groups were treated with the same amount of purified water. The offspring were assigned following the grouping method of their maternal generation. The behavioral changes of the offspring were tested by Morris water maze on 21^st day after birth， and the development of hippocampal neurons was observed by transmission electron microscopy. The mRNA and protein expression levels of methyltransferase-like 3 （METTL3）， METTL14， Wilms tumor 1 associated protein （WTAP）， fat mass and obesity-associated protein （FTO） and Alk B homologue 5 （ALKBH5） were detected by Real-time polymerase chain reaction （Real-time PCR）， Western blot and immunohistochemistry （IHC）. The total content of m⁶A in hippocampus was determined by high performance liquid chromatography tandem mass spectrometry （LC-MS/MS）. ResultCompared with the conditions in the blank group， the average latency duration in the model group was prolonged， and the number of entries in the target quadrant， the target quadrant duration and the number of crossing the platform were decreased （P<0.01）. Additionally， the model group had seriously damaged structure of hippocampal CA1 and CA3 neurons， swollen mitochondria， expanded endoplasmic reticulum， and small number of synapses with some having blurred structure， and the expression levels of METTL3， METTL14， FTO， ALKBH5 as well as the total m⁶A level were lower than those in the blank group （P<0.05，P<0.01）. Compared with the model group， the Cuscutae Semen group had shortened average latency duration， increased number of entries in the target quadrant， target quadrant duration and number of crossing the platform （P<0.01）， alleviated damage of hippocampal CA1 and CA3 neurons， fine structure of mitochondrial and endoplasmic reticulum， and clear， intact and dense synapses. And the expression levels of METTL3， METTL14， FTO as well as the total level of m⁶A were up regulated， while the expression level of ALKBH5 was down regulated in the Cuscutae Semen group （P<0.05，P<0.01）. ConclusionCuscutae Semen improved the learning and memory ability of the offspring of the rats affected by fear damaging kidney during pregnancy， protected hippocampal neurons， and up-regulated the expression levels of METTL3， METTL14， FTO and the total m⁶A level in hippocampus.

Claudin18.2(CLDN18.2)is a tight junction protein that is overexpressed in a variety of solid tumors such as gastrointestinal cancer and oesophageal cancer.It has been identified as a promising target and a potential biomarker to diagnose tumor,evaluate efficacy,and determine patient prognosis.TST001 is a recombinant humanized CLDN18.2 antibody that selectively binds to the extracellular loop of human Claudin18.2.In this study,we constructed a solid target radionuclide zirconium-89(89Zr)labled-TST001 to detect the expression of in the human stomach cancer BGC823CLDN18.2 cell lines.The[89Zr]Zr-des-ferrioxamine(DFO)-TST001 showed high radiochemical purity(RCP,＞99％)and specific activity(24.15±1.34 GBq/μmol),and was stable in 5％human serum albumin,and phosphate buffer saline(＞85％RCP at 96 h).The EC50 values of TST001 and DFO-TST001 were as high as 0.413±0.055 and 0.361±0.058 nM(P＞0.05),respectively.The radiotracer had a significantly higher average standard uptake values in CLDN18.2-positive tumors than in CLDN18.2-negative tumors(1.11±0.02 vs.0.49±0.03,P=0.0016)2 days post injection(p.i.).BGC823CLDN18.2 mice models showed high tumor/muscle ratios 96 h p.i.with[89Zr]Zr-DFO-TST001 was much higher than those of the other imaging groups.Immunohistochemistry results showed that BGC823CLDN18.2 tumors were highly positive(+++)for CLDN18.2,while those in the BGC823 group did not express CLDN18.2(-).The results of ex vivo biodistribution studies showed that there was a higher distribution in the BGC823CLDN18.2 tumor bearing mice(2.05±0.16％ID/g)than BGC823 mice(0.69±0.02％ID/g)and blocking group(0.72±0.02％ID/g).A dosimetry estimation study showed that the effective dose of[89Zr]Zr-DFO-TST001 was 0.0705 mSv/MBq,which is within the range of acceptable doses for nuclear medicine research.Taken together,these re-sults suggest that Good Manufacturing Practices produced by this immuno-positron emission tomog-raphy probe can detect CLDN18.2-overexpressing tumors.

Objective:To investigate the value of three-dimensional (3D) CT in diagnosing cricoarytenoid dislocation.Methods:From January 2021 to December 2021, 31 patients with unilateral cricoarytenoid dislocation who had been treated by reduction forceps at the Affiliated BenQ Hospital of Nanjing Medical University were collected retrospectively, and their voice recovered or improved significantly after therapy. The preoperative CT images were reconstructed by volume rendering (VR). The dislocated side (left and right), type of dislocation (total dislocation and subluxation), and dislocation direction (anterior, posterior, internal and external dislocation) of cricoarytenoid dislocation were observed. According to arytenoid articular surface of cricoid cartilage exposed completely or not (caused by arytenoid displacement), they were divided into complete dislocation and subluxation. According to the direction of arytenoid displacement and the part of arytenoid articular surface of cricoid cartilage exposed, they were divided into anterior, posterior, internal and external dislocation. According to the shape of the vocal cords on laryngoscope, anterior and posterior dislocation of each case was judged, and then compared with that of CT.Results:On VR images, there were 28 cases of cricoarytenoid subluxation (90.3%, 28/31) and 3 cases of complete dislocation (9.7%, 3/31). Left cricoarytenoid dislocation was 26 cases (83.9%, 26/31) and right cricoarytenoid dislocation was 5 cases (16.1%, 5/31). Posterior dislocation was 28 cases (90.3%, 28/31) and anterior dislocation was 3 cases (9.7%, 3/31). There were 23 cases of internal dislocation (74.2%, 23/31), 2 cases of external dislocation (6.4%, 2/31), and 6 cases without obvious internal and external dislocation (19.4%, 6/31). Three cases of complete dislocation were left posterior internal dislocation.There were 24 cases of left posterior dislocation (77.4%, 24/31), 4 cases of right posterior dislocation (12.9%, 4/31), 2 cases of left anterior dislocation (6.4%, 2/31) and 1 case of right anterior dislocation (3.2%, 1/31). On laryngoscope, there were 19 cases of posterior dislocation (61.3%, 19/31), 9 cases of anterior dislocation (29.0%, 9/31), 3 cases were difficult to assess (9.7%, 3/31) because of aryepiglottic fold covering. Sixteen cases (55.2%, 16/28) were consistent with 3D CT, and 12 cases (42.8%, 12/28) were inconsistent.Conclusion:The 3D CT is a reliable method to evaluate cricoarytenoid dislocation, which can show dislocated side, type and direction of cricoarytenoid dislocation clearly.

Objective:To compare the effectiveness and safety of mechanical thrombus aspiration combined with superior mesenteric artery transcatheter thrombolysis with those of simple superior mesenteric artery transcatheter thrombolysis in the treatment of portal vein-superior mesenteric vein thrombosis.Methods:A retrospective case-control study was used to analyze the clinical data of 27 patients with portal vein thrombosis treated by interventional therapy in Beijing Friendship Hospital Affiliated to Capital Medical University from February 2020 to October 2022. According to different interventional procedures, they were divided into two groups: 13 cases were treated with mechanical thrombus aspiration combined with superior mesenteric artery catheterization thrombolysis (combined treatment group), and 14 cases were treated with superior mesenteric artery catheterization thrombolysis alone (catheterization thrombolysis group). The postoperative and preoperative portal vein thrombus grade, catheterization thrombolysis time, parenteral nutrition time and operation-related complications were observed and compared between the two methods, and the incidence of long-term intestinal necrosis was compared after postoperative follow-up. Measurement data of normal distribution were expressed as mean±standard deviation( ± s), t-test was used for comparison between groups. Counting data were expressed as cases and percentage(%), and comparison between groups was used Chi-square test or Fisher exact probability method. Results:There was significant difference in the grade of portal vein thrombosis between the combined treatment group and the catheterization thrombolysis group( P<0.05). The thrombolytic time of catheterization in the two groups was (2.38±0.74) d and (4.79±1.15) d, respectively, and the time of parenteral nutrition was (4.08±2.87) d and (8.50±3.16) d, respectively. The difference was statistically significant ( P<0.05). There was no significant difference in operation-related complications between the two groups ( P>0.05). There were no severe injury of liver and kidney function in both groups. One patient in each group underwent long-term enterectomy. Conclusions:Mechanical thrombus aspiration combined with superior mesenteric artery thrombolysis is safe and effective in the treatment of portal vein thrombosis. Compared with simple superior mesenteric artery thrombolysis, mechanical thrombus aspiration combined with superior mesenteric artery thrombolysis can increase the rate of thrombus clearance and reduce the time of thrombolysis and parenteral nutrition support.

Objective:To analyze the safety and efficacy of G-iliac? iliac branch device (IBD) in the treatment of common iliac artery aneurysm.Methods:The clinical data of 7 patients with common iliac artery aneurysm who were treated with G-iliac? IBD and internal iliac artery (IIA) preserved were retrospectively analyzed in the Department of Vascular Surgery, Beijing Friendship Hospital, Capital Medical University from June 2021 to June 2022, and the surgical effects and related complications were analyzed.Results:All 7 patients were male, aged from 57 to 80 years, with an average age of 70.9 years. There were 6 cases of abdominal aortic aneurysm combined with common iliac artery aneurysm and 1 case of simple common iliac artery aneurysm, all of them were successfully applied with G-iliac? IBD to preserve IIA. Cardiogenic shock occurred in 1 patient after the operation. 7 patients were followed up for 3-15 months, with an average of 8 months. During the follow-up period, the iliac artery and IIA stents were all patency, and there was no IBD-related endoleak, stent displacement, buttock claudication, sexual dysfunction, or aortic-related death. The diameter of abdominal aortic aneurysm and common iliac artery aneurysm were stable.Conclusion:For patients with common iliac artery aneurysm, preservation of IIA with G-iliac? IBD is a safe and effective technique with a high technical success rate and IIA patency rate, and has a low complication rate, but the long-term effect still requires more data and longer follow-up data to support.

Objective:To investigate the influencing factors and clinical effect analysis of the choice of treatment method for spontaneous isolated superior mesenteric artery dissection (SISMAD).Methods:The clinical data of 35 patients with SISMAD admitted to Beijing Friendship Hospital, Capital Medical University from December 2015 to November 2021 were retrospectively analyzed. They were divided into conservative group ( n=24) and surgical group (endoluminal stent group + open surgery group, n=11). The conservative group was treated with conservative methods, the endoluminal stent group ( n=10) was treated with endoluminal stent placement, and the open surgery group ( n=1) was treated with superior mesenteric artery endarterectomy + angioplasty + ileal resection. The white blood cell (WBC) count on admission, the time of abdominal pain, YOO classification, aorta mesenteric angle(AMA), and the length of hospital stay between the two groups were analyzed. All patients were followed up for more than 24 months, at the end of which the vascular remodeling rate of superior mesenteric artery (SMA) between the two groups was studied. In addition, the primary patency rate and secondary patency rate of intracavitary stents were analyzed. Measurement data that conform to normal distribution were expressed as mean ± standard deviation ( ± s), and independent samples t-test was used for comparison between groups; measurement data that do not conform to normal distribution were expressed as median (interquartile range) [ M( Q1,Q3)], the nonparametric test was used for comparison between groups. Enumeration data were compared between groups using the Chi-square test. Results:Univariate analysis showed that compared with the conservative group, the IVS type in YOO classificationin of surgical group was significantly more than the conservative group. There was no significant difference in WBC, duration of abdominal pain, or AMA at admission ( P>0.05). In addition, the length of hospital stay in the conservative group was significantly shorter than that in the surgical group. No intestinal necrosis occurred in endoluminal stent group. After 24 months of follow-up, the remodeling rate of SMA in the surgical group was higher than that in the conservative group; the primary patency rate of the endoluminal stent group was 87.5%, and the secondary patency rate was 100%. One patient in the conservative group developed SMA dissection aneurysm during 12 months of follow-up and received endovascular treatment. Conclusions:For the treatment of SISMAD, most patients can be cured by conservative treatment. However, for patients with consistent abdominal pain and IVS type in YOO classification, if there is no severe manifestation of peritonitis, it is recommended to perform endovascular stent placement as soon as possible to open the blood supply. Meanwhile, the SMA stenting has an ideal long-term patency rate and vascular remodeling rate.

Objective:To evaluate the clinical efficacy of Rotarex percutaneous mechanical thrombectomy(PMT) for treatment of lower extremity arterial graft occlusion.Methods:The clinical data of 19 patients with lower extremity arterial bypass occlusion admitted to our hospital from January 2016 to December 2020 were retrospectively analyzed. All patients were treated with Rotarex-based endovascular therapy. After 12 months follow-up, the clinical features, surgical outcomes and follow-up data were analyzed to identify effectiveness and safety of the therapy. Independent sample t test was used to analyze the measurement data of continuous normal distribution which were expressed as mean±standard deviation( ± s), enumeration data were expressed as number and percentage, and the comparison between groups were analyzed by chi-square test. Results:A technical success rate of 100% was demonstrated. Rotarex combined with catheter directed thrombolysis was performed in 2 cases, Rotarex combined with percutaneous transluminal angioplasty (PTA) was performed in 9 cases. Rotarex combined with stent implantation was performed in 8 patients. The Ankle brachial index significantly increased (0.82±0.14 vs 0.47±0.11, P<0.05). Critical limb ischemia (Rutherford class 4 or higher) improved significantly (0 case vs 9 cases, P<0.05). Distal embolism occurred in 1 patient and acute myocardial infarction occurred in 1 patient. There was no vascular rupture, haemorrhage, infection, pseudoaneurysm, death and amputation. Kaplan-Meier survival analysis revealed 12-month primary patency rate and freedom from clinically driven target lesion revascularization was 78.9% and 89.5% respectively. Conclusion:Rotarex-based endovascular therapy is a safe and effective treatment for graft occlusion after lower extremity arterial prosthesis bypass with high patency rate and few complications.
