Objective To understand the prevalence,treatment and influence factors of hypertension in maintenance hemodialysis (MHD) patients in Anhui Province.Methods A total of 2724 adult patients on MHD from January 1st 2014 to March 31st 2014 in 26 hospitals of southern,northern and central Anhui Province were investigated.Their demographic characteristics,primary disease,complications,medications,dialysis and laboratory examination were explored.The prevalence treatment rate and control rate of hypertension were analyzed.Associated factors for controlling hypertension [systolic blood pressure (SBP) ＜ 140 mmHg and diastolic blood pressure (DBP) ＜ 90 mmHg] were assessed by logistic regression analysis.Results (1) The prevalence of hypertension in the hemodialysis patients was 87.0％.Their treatment rate and control rate were 93.2％ and 23.9％ respectively.The average of SBP was (145.90±21.18) mmHg,and the DBP on average was (83.60± 12.21) mmHg.The most commonly used anti-hypertensive drug is calcium channel blocker (88.2％).Over one third (45.7％) of patients were treated with two kinds of anti-hypertensive drug,26.2％ with 1 kind,21.7％ with 3 kinds,and 6.4％ with 4 kinds or more.(2) Compared with non-hypertension patients,patients with hypertension have older age,higher body mass index (BMI),phosphorus,SBP and DBP,as well as lower hemoglobin and Kt/V (all P ＜ 0.05).(3) The multivariate logistic regression analysis showed that Ca ＞ 2.50 mmol/L (OR=2.084,95％CI 1.008-4.307,P=0.047) positively correlated with controlling hypertension,while smoke (OR=0.594,95％CI 0.356-0.911,P=0.046) and BMI 18.5 ～ 23.9 kg/m2 (OR=0.516,95％CI 0.293-0.907,P=0.022) negatively correlated with it.Conclusions High prevalence yet low control rate of hypertension in MHD patients in Anhui Province were observed.Hypocalcemia may be a protective factor for hypertension control,while smoke and BMI may be risk factors for it.

Bispecific antibody (BsAb) has two different antigen-binding sites, divided into the "IgG-like" format and the "non-IgG-like" format. Different formats have different characteristics and applications. BsAb has higher sensitivity and specificity than conventional antibodies, with special functions such as recruitment of immune cells and blocking of dual signaling pathways, playing an important role in immune-diagnosis and therapy. With the deterioration of the global environment and the irregular living habits of people, the incidence of tumor is becoming higher and higher. Tumor becomes the most serious fatal disease threatening human health after cardiovascular disease. There are 12 million estimated new tumor cases each year worldwide. The major clinical treatments of tumor are surgical resection, chemoradiotherapy, target therapy. Tumor immunotherapy is a novel approach for tumor treatment in recent years, and activates human immune system to control and kill tumor cells. Although the traditional monoclonal antibodies have already acquired some therapeutic effects in tumor targeted therapy and immunotherapy, they induce drug resistance resulted from the heterogeneity and plasticity of tumors. Binding to two target antigens at the same time, BsAb has been used in the clinical treatment of tumors and obtained promising outcomes. This review elaborates the research progress and applications of bispecific antibody in clinical tumor therapy.

【Objective】 To observe the safety and effectiveness of endovascular treatment for mild stroke patients with acute anterior circulation large vessel occlusion. 【Methods】 The retrospective study enrolled 38 mild stroke patients with anterior circulation large vessel occlusion who received endovascular thrombectomy (EVT) at The First Affiliated Hospital of Xi’an Jiaotong University between January 2018 and August 2021. Vascular recanalization rate after endovascular treatment (mTICI≥2b), procedural complications, NIHSS score at discharge, and the rate of good modified Rankin Score (mRS≤2) at 90d were observed. 【Results】 The average age of the 38 patients was 62.89±12.41 years, and there were 21 males (55.3%). The vascular recanalization rate post EVT was 100%, while with three cases of thrombosis escape (7.9%) and one case (2.6%) of sICH of 24 h post EVT. The average NIHSS at discharge was 1 (0-1) point, which significantly decreased compared to the average baseline NIHSS 4 (4-5) points (P<0.01). The 90 d followed-up rate was 89.47%, and among all the followed-up patients, 91.2% of them had mRS≤2. Imaging follow-up showed good vascular flow and no in-stent restenosis. 【Conclusion】 Endovascular treatment for acute anterior circulation large vessel occlusion in mild stroke is safe and effective.

Primary liver cancer (PLC) is an aggressive tumor and prone to metastasize and recur. According to pathological features, PLC are mainly categorized into hepatocellular carcinoma, intrahepatic cholangiocarcinoma, mixed hepatocellular cholangiocarcinoma, and fibrolamelic hepatocellular carcinoma, etc. At present, surgical resection, radiotherapy and chemotherapy are still the main treatments for PLC, but the specificities are poor and the clinical effects are limited with a 5-year overall survival rate of 18%. Liver cancer stem cells (LCSCs) are a specific cell subset existing in liver cancer tissues. They harbor the capabilities of self-renewal and strong tumorigenicity, driving tumor initiation, metastasis, drug resistance and recurrence of PLC. Therefore, the identification of molecular markers and the illustration of mechanisms for stemness maintenance of LCSCs can not only reveal the molecular mechanisms of PLC tumorigenesis, but also lay a theoretical foundation for the molecular classification, prognosis evaluation and targeted therapy of PLC. The latest research showed that the combination of 5-fluorouracil and CD13 inhibitors could inhibit the proliferation of CD13+ LCSCs, thereby reducing overall tumor burden. Taken together, LCSCs could be the promising therapeutic targets of PLC in the future. This review summarizes the latest progress in molecular markers, mechanisms for stemness maintenance and targeted therapies of LCSCs.
