Research progress in effects of MAGE-A family on gastric cancer / 中南大学学报(医学版)

Gastric cancer (GC) is one of the most common malignant tumors worldwide, and most of the patients are diagnosed at the advanced stage. Most of the treating options are comprehensive treatment, in which immunotherapy plays more and more important role. Melanoma antigen-associated gene-A (MAGE-A) family is a kind of cancer testis antigens. Except in germ cells of testis and trophoblast cells of placenta, MAGE-A family is highly expressed in cancerous tissues and participates in a variety of biological processes, such as cancer cell proliferation, differentiation and metastasis. In addition, cancer testis antigen also possesses good immunogenicity, which can induce humoral and cellular immune responses, is a good target for immunotherapy, and has good application value in the diagnosis, treatment and prognosis of GC. A variety of targeted therapeutic drugs based on MAGE-A are in phase I or II clinical trials, it has good safety and potential clinical application value. With the continuous progress of clinical trials and basic research on MAGE-A targets in GC, it is expected to provide a theoretical basis for clinical transformation and immunotherapy of MAGE-A in the future.

Objective: To investigate the timing of pericardial drainage catheter removal and restart of the anticoagulation in patients with atrial fibrillation (AF) suffered from perioperative pericardial tamponade during atrial fibrillation catheter ablation and uninterrupted dabigatran. Methods: A total of 20 patients with pericardial tamponade, who underwent AF catheter ablation with uninterrupted dabigatran in Beijing Anzhen Hospital from January 2019 to August 2021, were included in this retrospective analysis. The clinical characteristics of enrolled patients, information of catheter ablation procedures, pericardial tamponade management, perioperative complications, the timing of pericardial drainage catheter removal and restart of anticoagulation were analyzed. Results: All patients underwent pericardiocentesis and pericardial effusion drainage was successful in all patients. The average drainage volume was (427.8±527.4) ml. Seven cases were treated with idarucizumab, of which 1 patient received surgical repair. The average timing of pericardial drainage catheter removal and restart of anticoagulation in 19 patients without surgical repair was (1.4±0.7) and (0.8±0.4) days, respectively. No new bleeding, embolism and death were reported during hospitalization and within 30 days following hospital discharge. Time of removal of pericardial drainage catheter, restart of anticoagulation and hospital stay were similar between patients treated with idarucizumab or not. Conclusion: It is safe and reasonable to remove pericardial drainage catheter and restart anticoagulation as soon as possible during catheter ablation of atrial fibrillation with uninterrupted dabigatran independent of the idarucizumab use or not in case of confirmed hemostasis.

Effect of Brain-computer Interface on Upper-limb Motor Function after Stroke: A Meta-analysis / 中国康复理论与实践

Objective:To systematically evaluate the effect of brain-computer interface (BCI) on upper-limb motor function after stroke, and compare the effects under different interfaces. Methods:Randomized controlled trials (RCTs) about BCI for upper-limb motor function after stroke were retrieved from databases of PubMed, Embase, Cochrane Library, Web of Science, CNKI, Wanfang Data and CBM, from inception to October, 2020. The quality of the trials was assessed and the data were extracted according to the Cochrane Handbook of Systematic Review. A meta-analysis was carried out with RevMan 5.3 and ADDIS 1.16.8. Results:Ultimately, 14 RCTs involving 504 patients were included. Meta-analysis showed that BCI could obviously improve the Fugl-Meyer Assessment-Upper Extremities (FMA-UE) score (MD = 6.81, 95%CI 1.51 to 12.11, P < 0.05), Action Research Arm Test score (MD = 7.68, 95%CI 0.49 to 14.88, P < 0.05) and modified Barthel Index score (MD = 8.91, 95%CI 5.57 to 12.25, P < 0.001) after stroke. Subgroup analysis showed that FMA-UE score could be improved by BCI for both more than four weeks (MD = 9.44, 95%CI 1.83 to 17.04, P < 0.05) and less than four weeks (MD = 5.18, 95%CI 2.84 to 7.51, P < 0.001). For the types of interface, the probabilities of the best effects from network meta-analysis ranked as electrical stimulator (P = 0.53), visual feedback (P = 0.41) and machine assistance (P = 0.06). Conclusion:BCI, especially with electrical stimulator interface, could obviously improve upper-limb motor function and activities of daily living for stroke patients.

A retrospective study to compare the treatment outcomes with and without surgical navigation for fracture of the orbital wall / 中华创伤杂志(英文版)

PURPOSE@#To evaluate the outcomes with and without aid of a computer-assisted surgical navigation system (CASNS) for treatment of unilateral orbital wall fracture (OWF).@*METHODS@#Patients who came to our hospital for repairing unilateral traumatic OWF from 2014 to 2017 were included in this study. The patients were divided into the navigation group who accepted orbital wall reconstruction aided by CASNS and the conventional group. We evaluated the surgical precision in the navigation group by analyzing the difference between actual postoperative computed tomography data and preoperative virtual surgical plan through color order ratios. We also compared the duration of surgery, enophthalmos correction, restoration of orbital volumes, and improvement of clinical symptoms in both groups systemically. Quantitative data were presented as mean ± SD. Significance was determined by the two-sample t-test using SPSS Version 19.0 A p < 0.05 was considered statistically significant.@*RESULTS@#Seventy patients with unilateral OWF were included in the study cohort. The mean difference between preoperative virtual planning and actual reconstruction outcome was (0.869 ± 0.472) mm, which means the reconstruction result could match the navigation planning accurately. The mean duration of surgery in the navigation group was shorter than it is in the control group, but not significantly. Discrepancies between the reconstructed and unaffected orbital-cavity volume and eyeball projection in the navigation group were significantly less than that in the conventional group. One patient had remnant diplopia and two patients had enophthalmos after surgery in the navigation group; two patients had postoperative diplopia and four patients had postoperative enophthalmos in the conventional group.@*CONCLUSION@#Compare with the conventional treatment for OWF, the use of CASNS can provide a significantly better surgical precision, greater improvements in orbital-cavity volume and eyeball projection, and better clinical results, without increasing the duration of surgery.

Objective: To evaluate the safety and effectiveness of left atrial appendage occlusion (LAAO) in patients with atrial fibrillation and end-stage renal disease undergoing long-term hemodialysis. Methods: Six patients with AF and end-stage renal disease(ESRD)on long term hemodialysis who underwent LAAO from March 2017 to March 2021 in Beijing Anzhen Hospital were enrolled. Baseline characteristics such as age, sex, types of arrhythmia, stroke and bleeding score, and continuous dialysis time were collected. Four patients underwent LAAO, two patients underwent the combined procedure of catheter ablation and LAAO. Perioperative treatment and serious complications were recorded. Transesophageal echocardiography was repeated at 45 days and 60 days after the procedure. Telephone follow-up was conducted at 3, 6 and 12 months after the procedure, and every 6 months thereafter. Thromboembolism and major bleeding events and survival were evaluated. Results: The average age was (66.7±17.0) years old, and 5 were male (5/6). There were 4 patients with paroxysmal AF (4/6), and 2 patients with persistent AF (2/6). The mean CHA2DS2-VASc score was (4.8±1.5), and the HAS-BLED score was (3.5±1.4). The duration of hemodialysis was 2.6 (1.1, 8.3) years. Successfully Watchman implantation was achieved in all patients. There were no severe perioperative complications, and no device related thrombosis or leaks were observed by transesophageal echocardiography. During a mean of 22.0 (12.0, 32.0) months follow-up, there was no thromboembolism or major bleeding events. A total of 2 patients died, one from sudden cardiac death, and another one from heart failure. Conclusions: LAAO may be a safe and effective therapeutic option for prevention of thromboembolism in patients with atrial fibrillation and end-stage renal disease undergoing long-term hemodialysis, further studies with larger patient cohort are needed to confirm our results.

Effectiveness and safety of idarucizumab in the management of perioperative complications of atrial fibrillation catheter ablation in atrial fibrillation patients under dabigatran therapy / 中华心血管病杂志

Objective: To investigate the efficacy and safety of idarucizumab in the treatment of perioperative cardiac tamponade and thromboembolic events during catheter ablation in atrial fibrillation (AF) patients under dabigatran therapy. Methods: This study was a retrospective analysis enrolling patients under dabigatran therapy, who underwent catheter ablation for AF at Beijing Anzhen Hospital from January 2019 to December 2020 and developed perioperative cardiac tamponade or acute ischemic stroke (AIS) and received idarucizumab to reverse the anticoagulant effect of dabigatran. Patients' age, sex, renal function, coagulation test and safety events at 30 d after idarucizumab administration were collected and analyzed. The clinical presentation and prognosis were also analyzed. Results: A total of 7 patients were included, 2 (2/7) were male, mean age was (66.3±11.2) years, serum creatinine level was (66.3±13.6) μmol/L, estimated glomerular filtration rate was (89.4±11.2) ml·min-1·1.73 m-2, CHA2DS2-VASc and HAS-BLED scores were (3.2±1.9) and (1.3±1.3), respectively. Five patients (5/7) developed cardiac tamponade during the perioperative period and the time interval to the last dose of dabigatran was (6.3±2.6) h. Idarucizumab was given at (36.4±16.7) min after the definitive diagnosis of cardiac tamponade. A significant decrease of activated partial thromboplastin time was achieved after idarucizumab administration in all five cases. Pericardial puncture and drainage were applied to all patients (5/5) with cardiac tamponade, the drainage volume was (1 037.0±846.9) ml, the retention time of pericardial drainage catheter was (27.9±13.9) h, and the recovery time of anticoagulation was (28.4±13.2) h. One patient (1/5) underwent thoracotomy for hemostasis due to excessive blood loss with the aim of ensuring complete hemostasis. Bleeding occurred in 1 patient (1/5) after the first restart of anticoagulation. AIS occurred in 2 patients (2/7) after operation. One case (1/2) received intravenous thrombolysis after receiving 5.0 g idarucizumab, no hemorrhagic transformation was observed, and the recovery process was satisfactory. Another patient in this group experienced significantly prolonged onset time and 5.0 g idarucizumab was applied before intravascular thrombectomy, there was no bleeding complication in this patient after thrombectomy. At the time of discharge, the consciousness was not significantly improved, and the muscle strength of the right lower limb was recovered somehow compared with that before operation. No hypersensitivity reactions or thrombotic events occurred in these patients within 30 days of the administration of idarucizumab. Conclusion: In AF catheter ablation-associated cardiac tamponade and AIS, idarucizumab is safe and effective in rapidly reversing the anticoagulant effect of dabigatran, use of thrombectomy saves valuable time for timely hemostasis and improvement of cerebral blood circulation.

Transcriptome sequencing and metabolome analysis reveal the mechanism of Shuanghua Baihe Tablet in the treatment of oral mucositis / 中国天然药物

Oral mucositis (OM) caused by cancer therapy is the most common adverse reaction in the radiotherapy of head and neck tumors. In severe cases, it can lead to the interruption of treatment, which affects the control of the disease and the quality of life. Shuanghua Baihe Tablet (SBT) is a traditional Chinese medicine (TCM) formula, which is administerd to treat OM in China. It has been clinically effective for more than 30 years, but the underlying mechanism is not completely understood. With the development of multiple omics, it is possible to explore the mechanism of Chinese herbal compound prescriptions. Based on transcriptomics and metabolomics, we explored the underlying mechanism of SBT in the treatment of OM. An OM model of rats was established by 5-FU induction, and SBT was orally administered at dosages of 0.75 and 3 g·kg

Composition and histopathological features of prostatic calculi in patients with benign prostatic hyperplasia / 中华男科学杂志

Objective@#To analyze the composition of prostatic calculus in patients with BPH and explore its pathogenic factors and histopathological characteristics.@*METHODS@#Strictly following the inclusion and exclusion criteria, we included in this retrospective study 580 cases of bipolar transurethral plasma kinetic prostatectomy (TUPKP) performed in our hospital from May 2015 to May 2019, analyzed the histopathological and calculus-composition features of the patients with BPH complicated by prostatic calculi (the BPH+PC group) and the histopathological data of those with BPH only (the BPH group). We compared the related factors between the two groups of patients and performed uni- and multivariate logistic regression analyses of the data on those in the BPH+PC group.@*RESULTS@#The incidence rate of chronic inflammation was significantly higher in the BPH+PC than in the BPH group (83.1% vs 61.1%, P 0.05). Logistic regression analyses showed that prostatic calculus was significantly correlated with chronic inflammation of the prostate, the patient's age and IPSS (P 0.05).@*CONCLUSIONS@#Prostatic calculus has a high incidence in BPH patients and varies widely in composition, chiefly consisting of calcium oxalate and carbonate apatite. The major factors contributing to prostatic calculi include chronic inflammation of the prostate (primarily the severe type), age and BPH. Prostate calculi may aggravate lower urinary tract symptoms, especially urinary storage symptoms, in patients with BPH, but not significantly affect the PSA level.？.

All the lesions of the patients in this group were considered as complex ICAS, i.e. with severe tortuous access, long (>10 mm) or occlusive or bifurcation lesions, with concurrent aneurysms near the stenotic lesion. The primary outcome was defined as any stroke (including ischemic or hemorrhagic) or deaths from any cause after stenting procedure within 30 days. The secondary outcome was defined as successful revascularization and occurrence of >50% in-stent restenosis during the follow-up period.@*RESULTS@#All the 18 patients achieved technical success (100%) and mean stenosis rate was reduced from 85%±7% to 18%±6%. Of the 18 patients included, the 30-day stroke or death was 5.6% (1/18), which presented as basal ganglia region infarction in a patient with tandem lesions on the left vertebral artery. There was no hemorrhagic and death complications that occurred in the patients of this group. One concurrent aneurysm was embolized with micro coil (stent assisted) by stages after 1 month. In this group 12 patients were followed up with digital subtraction angiography (DSA) after hospital discharge. The follow-up period ranged from 8 months to 26 months [mean: (16±8) months]．During the follow-up period 2 patients in the 12 patients (2/12, 16.7%) developed in-stent restenosis (ISR) confirmed by DSA, and one of them was symptomatic restenosis and restored unobstructed blood flow after balloon angioplasty.@*CONCLUSION@#Neuroform EZ stent for the treatment of highly screened symptomatic complex severe ICAS is safe and effective. It has its advantages over traditional stent.

Contribution of Tissue Hypoxia to Corpus Luteum Formation / 中国医学科学院学报

Corpus luteum is a temporary endocrine organ that is formed and regressed during the female reproductive cycle.It is developed from the residual follicular tissue after ovulation,which is associated with the rapid angiogenesis.Vascular endothelial growth factor(VEGF)is the most important stimulatory factor that regulates the luteal angiogenesis and also plays a key role during corpus luteum formation.VEGF is regulated by hypoxia-inducible factor(HIF)-1,which is a heterodimeric transcription factor consistent of HIF-1α and HIF-1β.The local hypoxia of ovary due to the ruptured follicle and the lack of new vascular networks induces HIF-1α expression and participates in the luteal formation through VEGF-dependent angiogenesis.The present article describes the functional and structural changes during the luteal formation from the local and hypoxic conditions immediately before and after ovulation,with an attempt to clarify the roles of hypoxia in luteal formation as well as ovarian physiology.

OBJECTIVE@#To investigate the effects of the Arg-Gly-Asp polypeptedes (RGD) peptides-modified porous tantalum surface on osteoblasts morphology and expressions of osteogenesis factors, and to evaluate RGD peptides promotes junctura ossium of tantalum-bone interface in vivo.@*METHODS@#RGD peptides of different concentrations (1 g/L, 5 g/L, and 10 g/L) were loaded to porous tantalum slices with a diameter of 10 mm and a thickness of 3 mm by physical absorption. The 3rd generation of MG63 cells were co-cultured with tantalum and divided into 4 groups: Ta-cells (control) group, 1 g/L cells/Ta/RGD group, 5 g/L cells/Ta/RGD group, and 10 g/L cells/Ta/RGD group. Porous tantalum compo-sites and osteoblasts-tantalum interface were observed by scanning electron microscopy. The adhesion rate of osteoblasts was detected and immunocytochemistry was used to detect the expressions of filamentous actin (F-actin), osteocalcin (OC) and fibronectin (FN).@*RESULTS@#The scanning electron microscope (SEM) revealed that osteoblasts distributed on the surface of porous tantalum and secreted extracellular matrix on outside and inner of micro-pores. The osteoblasts adhesion rate on porous tantalum modified with RGD was higher than that in the unmodified porous tantalum at the end of 24, 48, and 72 hours. The best adhesion effect was got in 5 g/L cells/Ta/RGD group at hour 48 [(68.07±3.80) vs. (23.40±4.39), P<0.05]. The results of immunocytochemistry showed that the expressions intensity of F-actin, OC and FN in osteoblasts on porous tantalum modified groups with RGD were stronger than that in the unmodified groups, and the expressions of 5 g/L cells/Ta/RGD group were significantly higher than those in the 10 g/L group and 1 g/L group [OC: (18.08±0.08) vs. (15.14±0.19), P<0.05; (18.08±0.08) vs. (14.04±0.61), P<0.05. FN: (24.60±0.98) vs. (15.90±0.53), P<0.05; (24.60±0.98) vs. (15.30±0.42), P<0.05. F-actin: (29.20±1.31) vs. (24.50±1.51), P<0.05; (29.20±1.31) vs. (16.92±0.40), P<0.05]. Correspondingly F-actin in osteoblasts was showed in longitudinal arrangement, and the expressions intensity was stronger than those OC and FN.@*CONCLUSION@#The RGD peptides is beneficial to enhance adhesion of osteoblast, spreading and reorganization of cytoskeleton on porous tantalum surface and improve the interface morphology, further promoting osteoblasts-tantalum conjunctive interface osseointegration.

OBJECTIVE Bingpian is an almost pure chemical with a chemical composition of (+)-borneol and has been historically used as a topical analgesic in traditional Chinese medicine for millen-nia. However, the clinical efficacy of topical bingpian lacks stringent evidence-based clinical studies and the underlying molecular mechanisms are unclear.This study verified the analgesic efficacy of topi-cal bingpian in humans, and elucidated the underling mechanisms in animal models of pain. METH-ODS The analgesic efficacy of topical bingpian was examined in a randomized,double-blind,placebo-controlled clinical study at the Shanghai Changzheng Hospital. Capsaicin, formalin, CFA or thermal caused pain/hyperalgesia were established in different mouse models,and bingpian-induced analgesia and the underlying mechanisms were studied in these models.The molecular targets of bingpian were examined by calcium imaging, patch-clamp recording and enzymatic activity assay in mouse sensory neurons or transfected HEK 293 cells. RESULTS (1)Topical application of bingpian leads to significantly greater pain relief than placebo does in a randomized, double-blind, placebo-controlled clinical study involving 122 patients with postoperative pain.(2)TRPM8 channel is the most sensitive molecular target of bingpian and mediates topical bingpian-induced analgesia in mice. (3)A downstream glutamatergic mechanism in the spinal cord contributes to topical bingpian-induced analgesia. (4)Bingpian shows mechanistic differences and advantages as a topical analgesic when compared with menthol.

Role of ADAM8 in tumor metastasis / 中国药理学通报

Tumor metastasis is one of the important biological characteristics of malignant tumor,which is closely related with the prognosis of the cancer patients.High expression of ADAM8 in varieties of tumors was revealed in many recent studies,and such aberrant expression played a crucial role in regulating of tumor metastasis.Studies showed that overexpression of ADAM8 attenuated the intercellular adhesion effect,promoted tumor angiogenesis,and enhanced the degradation of ECM as well as the releasing of cytokines.Therefore,suppression of ADAM8 may lead to inhibition of tumor metastasis,which makes ADAM8 a particular attractive target as it can be used as a prognostic indicator and a potential therapeutic target of malignant tumor.A review about the relations between ADAM8 protein′s abnormal expression and tumor occurrence was discussed in this paper,also include discussion about the mechanisms of ADAM8 protein′s disorder-induced tumor formation,as well as therapeutic strategies based on ADAM8-targeted,which may provide references for follow-up research and clinical treatment.

A total of two times of immunization were conducted, once for every two weeks. At different time points after immunization, the serum was separated from precaval vein blood to detect the level of IgG by enzyme linked immunosorbent assay (ELISA). Piglets were challenged with Taenia solium eggs on the 4th week after the last immunization and killed 3 months after infection. The cysticerci were separated to count and calculate the reduction rate of cysticerci. Blood from precaval vein was collected to separate serum and prepare peripheral blood lymphocytes (PBMC). The levels of IgG,IgG1 and IgG2a in serum sampl es and the levels of interleukin ( IL )-2 , interferon (IFN)-γ, IL-4 and IL-10 in PBMC culture supernatant were determined by ELISA. The level of PBMC proliferation was tested using methyltetrazolium (MTT) assay. Results In experimental group, the level of serum IgG increased from the 2nd to the 8th weeks after immunization, and reached the highest level on the 4th week after immunization (mg/L:270 . 64 ± 1 . 94 vs 207.74 ± 2.24, t=42.479, P<0.05). Reduction rate of cysticercus was 80.48%. Compared with control group, the levels of IgG and IgG2a in serum were significantly increased, while the level of IgG1 was significantly decreased (mg/L: 364.15 ± 11.52 vs 245.94 ± 8.81, 89.74 ± 1.13 vs 62.61 ± 0.84, 20.52 ± 1.00 vs 34.11 ± 0.65, t=16.303, 38.579, - 22.772, P < 0.05). The levels of IL-2 and IFN-γ in PBMC culture supernatant were significantly increased, while the levels of IL-4 and IL-10 were significantly decreased (ng/L:215.24 ± 3.31 vs 174.19 ± 2.14, 28.21 ± 0.27 vs 17.69 ± 0.28, 40.35 ± 0.34 vs 52.57 ± 0.29, 71.34 ± 0.36 vs 94.82 ± 0.45, t =20.839, 53.623,-54.743,- 81.266, P<0.05). The level of PBMC proliferation was significantly increased (0.620 ± 0.051 vs 0.242 ± 0.053, t=10.259, P<0.05). Conclusions It is concluded that the mixed rBb vaccine of Taenia solium might give piglets a certain protection. Th1 type immune response plays an important role in the protection.
