Machine learning-guided synthesis of nanomaterials for breast cancer therapy.

Breast cancer is a common malignant tumor, which mostly occurs in female population and is caused by excessive proliferation of breast epithelial cells. Breast cancer can cause nipple discharge, breast lumps and other symptoms, but these symptoms lack certain specificity and are easily confused with other diseases, thus affecting the early treatment of the disease. Once the tumor progresses to the advanced stage, distant metastasis can occur, leading to dysfunction of the affected organs, and even threatening the patients' lives.

Synovial fluid exosome-derived miR-182-5p alleviates osteoarthritis by downregulating TNFAIP8 and promoting autophagy through LC3 signaling.

Objective: To investigate the role of exosomal miRNAs from synovial fluid (SF) in osteoarthritis (OA) patients and investigate the underlying molecular mechanism.

Methods: Degenerated knee tissues were collected from male and female OA patients. Enzyme-linked immunosorbent assay (ELISA) was used to detect the differences in the expression of inflammatory indicators, including TNF-α, IL-6, and IL-10, between the degenerative and injury groups.

Long noncoding RNA NONHSAG053901 promotes diabetic nephropathy via stimulating Egr-1/TGF-β-mediated renal inflammation.

Diabetic nephropathy (DN) is an important factor leading to end-stage kidney disease that affects diabetes mellitus patients globally. Our previous transcriptome sequencing has identified a large group of differentially expressed long noncoding RNA (lncRNA) in early development of DN. On basis of this, we aimed to investigate the function of lncRNA NONHSAG053901 in DN pathogenesis.

Clinical efficacy of cognitive behavioral therapy for chronic subjective tinnitus.

Background: Although cognitive behavioral therapy (CBT) has been known with a theoretical basis for tinnitus patients, there still were lack of clinical evidence.

Objective: To evaluate the clinical efficacy of cognitive behavioral therapy (CBT) for treatment of chronic subjective tinnitus.

Methods: One hundred patients with chronic subjective tinnitus patients were randomly divided into control (50 cases) and intervention (50 cases) groups, which received the masking therapy and sound treatment and masking therapy and sound treatment plus CBT.

PTX3 in serum induces renal mesangial cell proliferation but has no effect on apoptosis.

The present study aimed to investigate the effect of pentraxin 3 (PTX3) on the regulation of proliferation and apoptosis in human glomerular mesangial cells (HMCs). Small interfering (si)RNA was designed and synthesized to inhibit the expression of endogenous PTX3, and the effects on the proliferation and apoptosis of HMCs were detected by flow cytometry and an MTT assay. Western blot analysis was used to detect the activation of mitogen-activated protein kinase (MAPK) proteins in HMCs with PTX3 knockdown.

Analysis of 3-dimensional finite element after reconstruction of impaired ankle deltoid ligament.

We compared four repair techniques for impaired ankle ligament deltoideum, namely Wiltberger, Deland, Kitaoka and Hintermann using a 3-dimensional finite element. We built an ankle ligament deltoideum model, including six pieces of bone structures, gristles and main ligaments around the ankle. After testing the model, we built an impaired ligament deltoideum model plus four reconstruction models.

The prediction roles of asymmetric dimethyl-arginine, adiponectin and apelin for macroangiopathy in patients with impaired glucose regulation.

Purpose: To investigate the effects of asymmetric dimethyl-arginine (ADMA), adiponectin (APN) and apelin in predicting macroangiopathy in impaired glucose regulation (IGR) patients.

Methods: A total of 210 patients undergoing oral glucose tolerance test were included in this study. They were classified to normal glucose tolerance (NGT, n=42), impaired fasting glucose (IFG, n=36), impaired glucose tolerance (IGT, n=92, including 44 IGT1 and 48 IGT2 patients) and IFG+IGT (n=40) groups.

Role of the tumor microenvironment in pancreatic adenocarcinoma.

Pancreatic cancer is a devastating disease with proclivity for early metastasis, which accounts for its poor prognosis. The clinical problem of pancreatic cancer is its resistance to conventional therapies, such as chemotherapy or radiation. Based upon these challenges, the focus of research on pancreatic cancer has shifted gradually towards the tumor microenvironment.

Expression of human papillomavirus and prognosis of juvenile laryngeal papilloma.

The aim of this study was to evaluate the correlation between clinical behavior and expression of human papillomavirus (HPV) in patients with juvenile laryngeal papillomatosis, in an attempt to develop an effective molecular biological method to predict prognosis. We included 37 patients with juvenile laryngeal papillomatosis in the study group and 10 cases each of juvenile vocal cord polyps and juvenile normal laryngeal mucosa as the control group. We detected HPV by immunocytochemistry and in situ hybridization, identified the virus type, and measured HPV-DNA content using a computer-assisted, color pathological image-analysis system.

Abnormal Patella Height Based on Insall-Salvati Ratio and its Correlation with Patellar Cartilage Lesions: An Extremity-Dedicated Low-Field Magnetic Resonance Imaging Analysis of 1703 Chinese Cases.

Background And Aims: Diagnostic performance of patellar position for patellar cartilage lesions remains unclear. The aim of this study was to assess the abnormal patella height and its correlation with chondral lesions of the patellofemoral joint in China.

Material And Methods: A total of 1703 consecutive patients who performed knee joint examination using an extremity-dedicated low-field magnetic resonance imaging were enrolled in this study.

Involvement of Notch1/Hes signaling pathway in ankylosing spondylitis.

We aimed to investigate the role of Notch1/Hes signaling pathway in the pathogenesis of abnormal ossification of hip ligament in patients with ankylosing spondylitis (AS). 22 AS patients scheduled for artificial hip arthroplasty were randomly chosen as AS group. As controls, we used 4 patients diagnosed with transcervical fracture who underwent hip replacement surgery.

Dextromethorphan provides neuroprotection via anti-inflammatory and anti-excitotoxicity effects in the cortex following traumatic brain injury.

Traumatic brain injury (TBI) is caused by primary and secondary injury mechanisms. TBI induces a certain amount of inflammatory responses and glutamate excitotoxicity that are believed to participate in the pathogenesis of secondary injury. The non‑narcotic anti‑tussive drug dextromethorphan (DM) has been reported to have a high safety profile in humans and its neuroprotective against a variety of disorders, including cerebral ischemia, epilepsy and acute brain injury.

MicroRNAs in colorectal cancer: potential biomarkers and therapeutic targets.

Colorectal Cancer (CRC) is one of the most common malignant tumors of gastrointestinal tract. The occurrence, development, diagnosis and prognosis have become a hot topic in current clinical research. However, current diagnosis and treatment still depend on the results of tumor imaging or pathology test.

Critical role of miRNAs in pancreatic cancer.

Pancreatic cancer (PC) is an aggressive malignancy with a high mortality rate and poor prognosis. Numerous investigations have shown that microRNA (miRNA) plays a vital role in PC. Thousands of miRNAs have been screened in PC and altered miRNAs, including circulating miRNAs, are associated with PC proliferation, apoptosis, metastasis, chemosensitivity, and radiosensitivity.

Diffuse miliary nodules in the bronchial mucosa observed by bronchoscopy: sarcoidosis or tuberculosis?

Background And Aims: Miliary tuberculosis is a form of tuberculosis that is characterized by a wide dissemination into lung fields. So far, no report has shown a miliary tuberculosis case where diffuse miliary nodules can be observed in airways by bronchoscopy. Here we reported a case of military tuberculosis that can easily be misdiagnosed as sarcoidosis.
