[Molecular Diagnosis and Pedigree Analysis of Rare Mutations in Non-coding Region of Gene].

Objective: To perform molecular diagnosis and pedigree analysis for one case with α-thalassemia who does not conform to the genetic laws, and explore the effects of a newly discovered rare mutation () on clinical phenotypes.

Methods: Blood samples of the proband and her family members were collected for blood routine analysis, and the hemoglobin components were analyzed by capillary electrophoresis. The common α- and β-globin gene loci in Chinese population were detected by conventional techniques (Gap-PCR, RDB-PCR).

Durable complete response to neoantigen-loaded dendritic-cell vaccine following anti-PD-1 therapy in metastatic gastric cancer.

Neoantigens are ideal targets for dendritic cell (DC) vaccines. So far, only a few neoantigen-based DC vaccines have been investigated in clinical trials. Here, we reported a case of a patient with metastatic gastric cancer who received personalized neoantigen-loaded monocyte-derived dendritic cell (Neo-MoDC) vaccines followed by combination therapy of the Neo-MoDC and immune checkpoint inhibitor (ICI).

A strategy of idarucizumab for pericardial tamponade during perioperative period of atrial fibrillation ablation.

Objective: To investigate theoptimal idarucizumab (dabigatran antagonist) usage strategy for patients with acute pericardial tamponade receiving uninterrupted dabigatran during catheter ablation for atrial fibrillation (AF).

Methods: Ten patients presenting acute pericardial tamponade while receiving uninterrupted dabigatran during catheter ablation for AF in Beijing Anzhen Hospital from January 2019 to July 2020 were enrolled and retrospectively analyzed. A "wait and see" strategy of idarucizumab was carried out for all patients; in brief, idarucizumab was applied following pericardiocentesis, comprehensive evaluation of bleeding and hemostasis.

Recent advances in chiral analysis for biosamples in clinical research and forensic toxicology.

This article covers current methods and applications in chiral analysis from 2010 to 2020 for biosamples in clinical research and forensic toxicology. Sample preparation for aqueous and solid biological samples prior to instrumental analysis were discussed in the article. GC, HPLC, capillary electrophoresis and sub/supercritical fluid chromatography provide the efficient tools for chiral drug analysis coupled to fluorescence, UV and MS detectors.

Clinical Characteristics and Prognostic Analysis of Patients With Signet Ring Cell Gastric Carcinoma.

We do not know the clinical and prognostic factors that influence the survival of patients with gastric signet ring cell carcinoma (SRC). Therefore, a retrospective review was undertaken of 219 patients with SRC who had undergone gastrectomy between January 2009 and December 2012 in our hospital. Patient age, sex, TNM stage, vessel carcinoma embolus, perineural invasion, tumor site and operation type, postoperative chemotherapy, and five-year overall survival were recorded and evaluated.

Perineural Invasion and Postoperative Complications are Independent Predictors of Early Recurrence and Survival Following Curative Resection of Gastric Cancer.

Purpose: To investigate the clinicopathological and prognostic factors related to early gastric cancer recurrence after curative resection.

Patients And Methods: Between October 2006 and August 2018, a total of 149 patients with recurrence of gastric cancer/adenocarcinoma of the esophagogastric junction after curative resection were enrolled from our treatment group. A retrospective clinical analysis was performed on these patients with gastric cancer recurrence after curative resection.

Association of Tumor Protein p53 and Ataxia-Telangiectasia Mutated Comutation With Response to Immune Checkpoint Inhibitors and Mortality in Patients With Non-Small Cell Lung Cancer.

Importance: Immune checkpoint inhibitors (ICIs) can elicit durable antitumor responses in patients with non-small cell lung cancer (NSCLC), but only 20% to 25% of patients respond to treatment. As important genes in the DNA damage response pathway, comutation in the tumor protein p53 (TP53) and ataxia-telangiectasia mutated (ATM) genes may be associated with genomic instability and hypermutation. However, the prevalence of TP53 and ATM comutation and its association with response to ICIs are not fully understood.

Downregulation of serum CXCL4L1 predicts progression and poor prognosis in prostate cancer patients treated by radical prostatectomy.

Our previous study found that plate factor-4 variant (CXCL4L1) was downregulated in the serum of patients with prostate cancer (PCa). The aim of the present study was to investigate the prognostic value of CXCL4L1 in PCa. In total, 213 PCa patients treated with radical prostatectomy were enrolled and peripheral blood samples of all patients were collected.

[Risk factors and prevalence of cardiovascular disease of rural residents in Xianghe of Hebei province].

Objective: To observe the risk factors and prevalence of cardiovascular disease, and predict the 10-year risk of ischemic cardiovascular disease (ICVD) of a rural residents in Xianghe of Hebei province.

Methods: Two thousand five hundred and thirty two adults ( ≥ 35 years old) were surveyed at internal medicine outpatient department of Xianghe asthma hospital in Hebei province by face-to-face interview, physical examination and biochemical test. Subjects aged 35 to 59 were also evaluated using the National 10-year Risk Assessment for ICVD.

[The prevalence, awareness, and control of hypertension in Xianghe county of Hebei province].

Objective: To investigate the prevalence, awareness, control status and associated risk factors of hypertension in a rural population in Xianghe county in North China.

Methods: A total of 830 adults (aged ≥ 35) from Xianghe county were examined during July to August, 2011. Blood pressure was obtained using a standardized sphygmomanometer after a 5-minute sitting rest.
