Postoperative proliferative vitreoretinopathy (PVR) remains a dilemma for retinal surgeons. We performed a literature search and meta-analyses to figure out whether combined 5-fluorouracil (5-FU) and low molecular weight heparin (LMWH) treatment were effective in improving the primary success of vitrectomy and preventing postoperative PVR occurrence in patients with retinal detachment (RD). Databases including PubMed, Embase, the Cochrane library, and China National Knowledge Infrastructure (CNKI) were searched from inception to May 2021.

Background: It is a challenging problem to differentiate obstructive hydronephrosis from noninvasive evaluation of renal pelvis and ureteral motility in patients. The purpose of this study was to explore the value of 640-slice dynamic volume CT (DVCT) in the quantitative measurement of upper urinary tract (UUT) pump function after acute unilateral lower ureteral obstruction in pigs.

Methods: In this study, a perfusion pig model was constructed by constant pressure perfusion testing of the renal pelvis and left nephrostomy.

The incidence of hypoxic pulmonary hypertension (HPH) is increasing. Accumulating evidence suggests that long noncoding RNAs (lncRNAs) play an important role in HPH, but the functions and mechanism have yet to be fully elucidated. In the present study, we established a HPH rat model with 8 h of hypoxia exposure (10% O2) per day for 21 days.

Mesenchymal stem cell derived (MSC) exosomes are extracellular vesicles with a diameter of about 50-200 nm. Exosomes contain a large number of biologically active substances including mRNAs, miRNAs, cytokines, chemokines, proteins, lipids, etc. MSC exosomes exert biological effects through paracrine and endocrine pathways in vivo.

Graves' ophthalmopathy, also known as thyroid-associated orbitopathy (TAO), is the most common inflammatory eye disease in adults. The most common etiology for TAO is Graves' disease (GD); however, proteomic research focusing on differences between GD and TAO is limited. This study aimed to identify differentially expressed proteins between thyroid-associated orbitopathy (TAO) and GD.

Diabetic cardiovascular diseases (DCVDs) are the most common complications of diabetes mellitus and are considered to be one of the most important threats to global health and an economic burden. Long noncoding RNA (lncRNA), circular RNA (circRNA), and miRNA are a novel group of noncoding RNAs that are involved in the regulation of various pathophysiological processes, including DCVDs. Interestingly, both lncRNA and circRNA can act as competing endogenous RNA of miRNA, thereby regulating the expression of the target mRNA by decoying or sponging the miRNA.

Discovery of a novel short peptide with efficacy in accelerating the healing of skin wounds.

Pharmacol Res

January 2021

Department of Anatomy and Histology & Embryology, Faculty of Basic Medical Science, Kunming Medical University, Kunming, Yunnan, 650500, China. Electronic address:

Despite extensive efforts to develop efficacious therapeutic approaches, the treatment of skin wounds remains a considerable clinical challenge. Existing remedies cannot sufficiently meet current needs, so the discovery of novel pro-healing agents is of growing importance. In the current research, we identified a novel short peptide (named RL-QN15, primary sequence 'QNSYADLWCQFHYMC') from Rana limnocharis skin secretions, which accelerated wound healing in mice.

PDGF mediates pulmonary arterial smooth muscle cell proliferation and migration by regulating NFATc2.

Mol Med Rep

January 2021

Department of Respiratory Medicine, The Fourth Affiliated Hospital of Kunming Medical University, The Second People's Hospital of Yunnan Province, Kunming, Yunnan 650021, P.R. China.

The reconstruction of pulmonary vascular structure caused by the proliferation and migration of pulmonary arterial smooth muscle cells (PASMCs) is the central link in the formation of pulmonary arterial hypertension (PAH). Platelet‑derived growth factor (PDGF) can regulate the proliferation and migration of PASMCs. At the same time, nuclear factor of activated T cells (NFATs) plays an important role in the development of PAH.

Mucin1 (MUC1) upregulation in colon cancer has been linked to poor patient outcomes and advanced stage at diagnosis. This is partially due to MUC1-mediated inhibition of T-cell proliferation affecting efficient lysis by cytotoxic lymphocytes, which contributes to escape from immune surveillance. In the present study, human colorectal cancer tissues were collected, and MUC1-positive and MUC1-negative colon cancer mouse models were prepared; subsequently, the number and function of immune cells in tumor tissues were measured using flow cytometry.

Lung cancer has a high mortality rate worldwide. Non‑SMC condensin I complex subunit H (NCAPH) has been identified to be one of the regulatory subunits of the condensin I complex, which is essential for the correct packaging and segregation of chromosomes in eukaryotes. NCAPH is abnormally overexpressed in various types of cancer.

Type 2 diabetes mellitus (T2DM) has a high global prevalence, and insufficient insulin secretion is one of the major reasons for its development. Therefore, investigating the association between T2DM and the single nucleotide polymorphisms (SNPs) in genes associated with insulin secretion is necessary. T2DM (1,194) and nondiabetic (NDM) (1,292) subjects were enrolled and the ten single nucleotide polymorphisms (SNPs) in , , and associated with insulin secretion were genotyped in a Chinese population.

Article Synopsis
  • Osteoarthritis (OA) is a chronic joint disease that leads to cartilage degeneration, and cell-based therapies like mesenchymal stem cells are being explored as new treatments, though more research is needed.
  • A study analyzed data from 13 randomized controlled trials, finding that cell-based therapy didn’t significantly improve the WOMAC score after 6 months, but did lead to better KOOS scores and pain relief at 12 months.
  • High-dose adipose-derived mesenchymal stem cells showed promising long-term benefits without safety issues, suggesting potential advantages over other treatments and calling for further investigation.

Diabetic retinopathy (DRP) is a retinal disease caused by diabetes mellitus, which is categorized by microvascular lesions present in the retina such as vascular leakage, vascular proliferation, and retinal ischemia. The plan of the present study was to the synthesis of Cyperus rotundus-loaded zinc oxide nanoparticles (CR-ZnONPs) which was confirmed by the various characterization methods such as UV-vis spectroscopy, energy dispersive X-ray analysis, Fourier transform infrared, scanning electron microscope, and X-ray diffraction. Also, the effect of CR-ZnONPs on DRP-induced rats was determined by food intake, fasting blood glucose (FBG), HbA1c, insulin, retina thickness, inner nuclear layer (INL), outer nuclear layer (ONL) thickness, lipid peroxidation (LPO), catalase (CAT), glutathione peroxidase (GPx), and superoxide dismutase (SOD).

Background: Diabetic retinopathy (DR) is a specific neurovascular complication of diabetes mellitus (DM). Clinically, family history is a widely recognized risk factor for DR, assisting diagnosis and risk strata. However, among a great amount of DR patients without hereditary history like hypertension and diabetes, direct and simple risk factors to assist clinical decisions are still required.
