Objective To observe the intervention effects of Xintongfang on the expression of P-selectin (PS), P-selectin glycoprotein ligand-1 (PSGL-1), platelet-leukocyte aggregates (PLA) and platelet-monocyte aggregates (PMA) in patients of coronary heart disease with carotid artery plaque. Methods Sixty patients were randomly divided into Xintongfang group and the control group, with 30 cases in each group. Xintongfang group was given Xintongfang, the control group was given aspirin and atorvastatin calcium for two months. The expression of PS, PSGL-1, PLA and PMA were tested by flow cytometry before and after treatment. Results The expression of PS, PSGL-1, PLA and PMA in two groups were reduced (P<0.01). Xintongfang group had more obvious effects on the expression of PLA and PMA than the control group (P<0.05). Conclusion Xintongfang can reduce the degree of inflammatory in patients of coronary heart disease with carotid artery plaque by inhibiting platelet-leukocyte interaction.

Objective To explore the computed tomography (CT)manifestations of adrenocortical oncocytoma (ACO)for better understanding the disease and improving its diagnosis accuracy.Methods The CT manifestations of 9 cases with adrenocortical onco-cytomas confirmed by surgery were retrospectively reviewed and compared with pathological results.Results Five of cases were lo-cated in left side while 4 cases were in right side.Well defined and round or oval border could be found in all the cases.Of all the ca-ses,3 cases were solid lesions with equal density,< 3 cm in diameter,and mild consistent intensification after enhancement.Cystic lesion was detectd in 6 cases with > 3 cm in diameter.The mixed cystic and solid components with polycystic changes could be found on CT image,and remarkable intensification on solid lesion while no intensification on cystic lesion after the enhancement. Moreover,patchy or cotton-like shape could be found on solid lesion in 4 cases and 1 case with island like intensification;reticular pattern could be found in the central of lesion in 3 cases and 1 case with stellate shape.Pathological observation showed that the on-cotytomas were comprised of cells with abundant eosinophilic cytoplasm and necrotic and fibrous capsule without pathological mitosis could be found in some of lesion.Conclusion The characteristic CT features of adrenocortical oncotytoma has a worse specificity,its diagnosis was dependent on pathologic examination.

Objective To explore Wang Xingkuan’s rules of syndrome and treatment of chest blocking and heartache (Xiongbixintong).Methods Collection of professor Wang Xingkuan’s 267 consilia of patients with Xiongbixintong for outpatients. Chinese medicine terminology was regulated and Excelldatabase was established. Symptom, syndrome element, pathogenesis and treatment were statistically described by using Weka3.6 software, and Apriori algorithm was adopted for the main pathogenesis→treatment analysis of association rules.Results Symptoms include:chest pain, heart palpitations, shortness of breath, pale tongue (dark) red, etc. Syndrome elements include:in liver, and heart, and blood stasis, phlegm, qi stagnation, etc. The key pathogenesis is liver-heart imbalance, including stagnation of liver qi, heart and blood stasis, deficiency of heart qi-ying, disturbing heart-mind, etc. The principle of treatment is liver-heart Tongzhi, so the treatment is of“liver” with Shu gan-mu;treatment of“heart” contains freeing channels, eliminating phlegm and blood stasis, quiet the heart, replenishing qi-ying, etc. The main pathogenesis related credibility→treatment was higher than 0.50;with high reliability, the liver-heart imbalance→liver-heart Tongzhi was 0.71. Medication includes catharsis and tonic,“catharsis” to salvia, allium macrostemon, pseudo-ginseng, bupleurum, etc;“tonic” to white ginseng, ophiopogon japonicus, radix paeoniae alba, poria with hostwood, polygala tenuifolia, etc. Conclusion “Xintongzhigan, liver-heart Tongzhi, catharsis and tonic” is Wang Xingkuan’s thoughts and experience in treating Xiongbixintong.

Objective:To investigate the relationship between TP53 gene mutation and overall survival (OS) time of myelodysplastic syndrome (MDS).Methods:Databases, including PubMed, Cochrane Library and Embase were searched for relevant studies published up to 20 October, 2019. The corresponding hazard ratio ( HR) and their 95% confidence interval ( CI) for OS from multivariate Cox proportional hazard models were extracted. The combined HR with their 95% CI was calculated by using fixed or random effect models. Meta-analysis was performed by using Revman 5.3 software. Results:A total of 1 033 patients from 6 studies were enrolled. Meta-analysis results showed that OS time in TP53 gene mutation group was shorter than that in wild type group for patients with MDS ( HR = 2.16, 95% CI 1.52-3.07, P < 0.01). The prognostic risk for post-transplantation patients with MDS ( HR = 2.69, 95% CI 1.63-4.43, P < 0.01) was lower compared with that for patients treated by azacitidine( HR = 2.89, 95% CI 1.37-6.08, P = 0.005). Conclusion:TP53 gene mutation is a risk factor affecting OS of MDS patients.

Background: Bovine papilloma is a neoplastic disease caused by bovine papillomaviruses (BPVs), which were recently divided into 5 genera and at least 24 genotypes. Objectives: The complete genome sequence of BPV type 15 (BPV Aks-02), a novel putative BPV type from skin samples from infected cows in Southern Xinjiang China, was determined by collecting warty lesions, followed by DNA extraction and amplicon sequencing. Methods: DNA was analyzed initially by polymerase chain reaction (PCR) using the degenerate primers FAP59 and FAP64. The complete genome sequences of the BPV Aks-02 were amplified by PCR using the amplification primers and sequencing primers. Sequence analysis and phylogenetic analysis were performed using bio-informatic software. Results: The nucleotide sequence of the L1 open reading frame (ORF) of BPV Aks-02 was 75% identity to the L1 ORF of BPV-9 reference strain from GenBank. The complete genome consisted of 7,189 base pairs (G + C content of 42.50%) that encoded 5 early (E8, E7, E1, E2, and E4) and 2 late (L1 and L2) genes. The E7 protein contained a consensus CX2CX29CX 2 C zinc-binding domain and a LxCxE motif. Among the different members of this group, the percentages of the complete genome and ORFs (including 5 early and 2 late ORFs) sequence identity of BPV Aks-02 were closer to the genus Xipapillomavirus 1 of the Xipapillomavirus genus.Phylogenetic analysis and sequence similarities based on the L1 ORF of BPV Aks-02 revealed the same cluster. Conclusions The results suggest that BPV type (BPV Aks-02) clustered with members of the Xipapillomavirus genus as BPV 15 and were closely related to Xipapillomavirus 1.

Objective:To analyze the number of appeals volume and causes for complaints received by the government hotline against a hospital in Yangzhou during the pandemic of novel coronavirus pneumonia(hereinafter referred to as COVID-19), so as to provide reference for handling such hotline complaints during pandemics.Methods:Retrospective comparative analysis was made on the " 12345" government hotline work orders received from July 28, 2020 to August 28, 2020(routine prevention and control period) and July 28, 2021 to August 28, 2021(pandemic closure and control period). A descriptive analysis was made on the cause types of complaints and the distribution of departments in question, along with an analysis of the correlation between the cumulative number of cases of pandemic development and the number of complaints using Spearman rank correlation method.Results:The number of work orders for a hospital in Yangzhou during the pandemic control period(659 cases) was 7.7 times higher than that in the routine control period(76 cases). Management problems accounted for 96.7%(637 cases) in the level-1 type of the causes of complaints during the closure and control period of the pandemic, and workflow problems accounted for 90.9%(599 cases) in the level-2 type, which increased by 28.3 and 27.7 percentage points respectively compared with the routine prevention and control period; The highest proportion in the level-3 type of causes for complaints during the closure and control period of the pandemic was administrative management, accounting for 87.9%(579 cases). The departments being complained the most during the pandemic incubation period, outbreak period and recovery period of the pandemic were the fever clinic, oncology department and discharge center respectively. The cumulative number of cases of pandemic development was positively correlated with the number of complaints.Conclusions:During the COVID-19, the handling of the government hotline should be analyzed along with the causes of complaints, focusing on patients′ demands, providing timely feedback, developing collaborative management measures, and achieving accurate policy implementation.

Objective To study the correlation between carotid bifurcation geometry and atherosclerotic plaque vulnerability using high-resolution magnetic resonance vessel wall imaging(HRMR-VWI),and to seek the potential predictor for vulnerable plaque for-mation.Methods The clinical information and imaging data of 104 patients with carotid bifurcation plaque detected by HRMR-VWI were analyzed retrospectively.Carotid bifurcation geometric parameters was measured to determine whether the carotid bifurcation plaque was vulnerable plaque,and they were divided into vulnerable plaque group(69 cases)and stable plaque group(35 cases).The difference of carotid bifurcation geometry of various groups was investigated,and the influence of common traditional risk factors to obtain independent risk factors was adjusted.Receiver operating characteristic(ROC)curve was drawn.Results Among 104 carotid artery,vulnerable plaque group had larger bifurcation angle(54.00 vs 48.80,P＜0.001),less luminal expansion(1.76 vs 1.94,P=0.002)and less outflow/inflow area ratio(0.79 vs 0.88,P＜0.001)compared with stable plaque group.After adjusting,binary logistic regres-sion indicated that bifurcation angle[odds ratio(OR)1.132 per 10° increase;95％confidence interval(CI)1.044-1.225],luminal expan-sion(OR 0.084 per 1 increase;95％CI 0.014-0.492)and outflow/inflow area ratio(OR 0.357 per 0.01 increase;95％CI 0.177-0.723)were independent risk factors of vulnerable plaque formation.Bringing them into the final model,the area under the curve(AUC)was 0.878 above the basic model(AUC=0.664).Conclusion Bifur-cation angle,luminal expansion and outflow/inflow area ratio are independently associated with vulnerable plaque formation.Carotid bifurcation geometry have the certain predictive efficiency of vulnerable plaque formation and have the incremental diagnostic value to traditional risk factors,which are expected to be effective imaging makers for the formation of vulnerable plaque.

Ferroptosis is a new type of programmed cell death that is closely associated with the pathophysiological process of ischemic stroke. Ferroptosis inhibitors can improve neurological function and provide neuroprotection after cerebral ischemia. Therefore, the role of ferroptosis in ischemic stroke and the regulation of ferroptosis to intervene in the occurrence and development of ischemic stroke have become a research hotspot. This article reviews the molecular mechanism and potential therapeutic targets of ferroptosis during ischemic stroke, hoping to provide new perspectives for the treatment of ischemic stroke.
