Expert consensus on the clinical application of immunotherapy in breast cancer: 2024.

Background: Significant progress has been made in immunotherapy of breast cancer (BC) with the approval of multiple immune checkpoint inhibitors (ICIs), particularly in early and metastatic triple-negative breast cancer (TNBC) settings. Most guidelines have recommended immune therapy as the important approach in BC, yet several critical aspects still require further clarification, including proper patient selection, treatment duration, optimized chemotherapy partner, predictive biomarkers, and specific considerations for Chinese patients.

Methods: (I) Establishment of expert group: the expert group consists of 32 experts from departments such as medical oncology, breast surgery, and pathology; (II) literature search: mainly conducted in English databases (such as PubMed, Embase, and Cochrane Library) and Chinese databases (such as China National Knowledge Infrastructure, China Biology Medicine disc, and Wanfang Database), with a search cutoff date of April 23, 2024; (III) assessment of evidence quality and recommendation strength: evidence quality and recommendation opinions are graded based on the evidence category and recommendation level of the Chinese Society of Clinical Oncology (CSCO) guidelines; (IV) consensus formulation: on the March 2, 2024, through online consensus meeting, the consensus content is thoroughly discussed, and opinions from all experts are solicited.

Evaluation of a tuberculous abscess on the right side of the diaphragm with contrast-enhanced computed tomography: A case report.

We herein investigate the case of a patient with a tuberculous diaphragmatic abscess confirmed by pathology. The patient underwent plain computed tomography (CT) examination of the chest and contrast-enhanced abdominal CT examination. The abscess appeared as hypodense mass with thick and irregular wall, which was enhanced on the contrast-enhanced CT images.

Evaluation of MYOC, ACAN, HGF, and MET as candidate genes for high myopia in a Han Chinese population.

Aim: To investigate the association between high myopia (HM) and single nucleotide polymorphisms (SNPs) in the myocilin (MYOC), hepatocyte growth factor (HGF), hepatocyte growth factor receptor (MET), and aggrecan (ACAN) genes in a Han Chinese population.

Methods: Sixteen SNPs were genotyped by the SNaPshot method in a subject group composed of 1052 HM patients and 1070 controls. Statistical analysis was performed to determine the association between the SNPs and the susceptibility of HM.

HTUPA as a new thrombolytic agent for acute myocardial infarction: a multicenter, randomized study.

Background: It is necessary to develop a new thrombolytic agent which can be used by a single bolus at first aid sites to decrease the time to reperfusion in clinical practice. HTUPA, a genetically engineered new thrombolytic with a longer half-life, is well qualified. We aim to compare the thrombolytic efficacy and safety of human tissue urokinase type plasminogen activator (HTUPA) to recombinant tissue plasminogen activator (rt-PA) in Chinese patients with acute myocardial infarction (AMI).

Impact of NPM, TFF3 and TACC1 on the prognosis of patients with primary gastric cancer.

Background: NPM, TFF3 and TACC1 are molecular markers that play important roles in cell differentiation. Herein, we investigated their prognostic impact in patients with primary gastric cancer (GC) and determined whether they could be used as markers of more aggressive gastric carcinomas by detecting the extent of expression in human gastric carcinoma samples.

Methodology/principal Findings: Tumor tissue specimens from 142 GC patients were retrospectively retrieved and immunohistochemically evaluated.

[Hypoxia reduces the proliferation and occludin expression of primary sertoli cells].

Objective: To investigate the effect of hypoxia on the proliferation and occludin expression of primary rat Sertoli

Methods: We constructed a primary Sertoli cell system by two-step enzymatic digestion in 18 -22 days old Wistar rats and identified it by oil red O and immunofluorescence methods. We randomly divided the Sertoli cells into five groups to be cultured in oxygen at the concentrations of 20%, 15%, 10%, 5% and 1%, respectively, for 6, 12, 24, 48 and 72 hours. We detected the proliferation of the Sertoli cells by CCK-8 assay, determined the expression of occludin by Western blot, and analyzed the differences among the five groups.

Percutaneous Transluminal Revascularization following an Angiotensin Receptor Blocker: Successful Treatment for Flash Pulmonary Edema and Hyponatremic Hypertensive Syndrome.

Either flash pulmonary edema or hyponatremic hypertensive syndrome has been described in renal artery stenosis. However, coexistence of these two disorders has never been previously reported. We describe a patient who presented with flash pulmonary edema and hyponatremic hypertensive syndrome associated with bilateral renal artery disease (one complete occlusion, one highly critical renal artery stenosis, the equivalent of unilateral stenosis of a solitary functioning kidney).

Clinicopathologic characteristics and prognostic factors in patients with operable HER-2 overexpressing breast cancer.

Objective: To study the relationship between clinical pathologic characteristics, treatment modalities and prognostic factors in HER-2 (Human Epidermal growth factor Receptor-2) overexpressed breast carcinoma.

Materials And Methods: Major clinico-pathological factors including therapeutic modalities and survival status of 371 breast cancer patients with HER2 over-expression, teated at Yantai Yuhuangding Hospital from March of 2002 to December of 2010 were retrospectively studied, with special attention focused on survival-related factors.

Results: The median age of the total 371 patients in this study was 48 years at time of diagnosis, among which, the leading pathological type was infiltrating ductal carcinoma (92.

High-frequency variant p.T60M in NaCl cotransporter and blood pressure variability in Han Chinese.

Objective: Frequent studies have confirmed that homozygous or compound heterozygous loss-of-function mutation p.Thr60Met in NaCl cotransporter (NCC) lead to the salt-wasting Gitelman's syndrome (GS) of hypotension. The finding that Thr60 is a key SPAK/OSR1 phosphorylation site on NCC also raises the possible importance of Thr60 in regulating the activity of NCC and blood pressure (BP).

DNA methylation changes in cervical cancers.

Cervical carcinoma is one of the major causes of death in women worldwide. It is difficult to foresee a dramatic increase in cure rate even with the most optimal combination of cytotoxic drugs, surgery, and radiation; therefore, testing of molecular targeted therapies against this malignancy is highly desirable. Cervical cancer is a multistep process with accumulation of genetic and epigenetic alterations in regulatory genes, leading to activation of oncogenes and inactivation or loss of tumor suppressor genes (TSGs).

Biologically inhibitory effects of VEGF siRNA on endometrial carcinoma cells.

Objective: To study the biological effects of small inhibitory RNA (siRNA) on endometrial carcinoma cells through disrupting the mRNA of Vascular endothelial growth factor (VEGF), and its inhibitory functions on tumor cells' proliferation.

Methods: The sequence-specific siRNA of VEGF165 and the mock siRNA were designed, they were transfected into the endometrial carcinoma cell line, Ishikawa cells. Total cell RNAs were extracted from the transfected cells.

Coexistence of normotensive primary aldosteronism in two patients with Gitelman's syndrome and novel thiazide-sensitive Na-Cl cotransporter mutations.

Background: Primary aldosteronism (PA) is the most common form of secondary hypertension, while Gitelman's syndrome (GS) is the most common inherited renal tubular disease. However, coexistence of these two diseases has never been previously reported. AIM AND SUBJECTS: The aim of our study was to describe the association of GS and PA in two unrelated patients and compare their clinical presentation with a group of patients with GS.

A novel SLC12A3 splicing mutation skipping of two exons and preliminary screening for alternative splice variants in human kidney.

Background: Gitelman's syndrome is a mild autosomal recessive disorder caused by inactivating mutations of SLC12A3. However, severe phenotype may be associated with compound heterozygous nonfunctional variants such as frameshift and splicing mutations. Because most multi-exon genes are alternatively spliced as shown by recent studies, SLC12A3, with 26 exons, is likely to be alternatively spliced as well.
