Self-Powered Cathodic Photoelectrochemical Aptasensor Comprising a Photocathode and a Photoanode in Microfluidic Analysis Systems.

An intriguing self-powered cathodic photoelectrochemical (PEC) microfluidic aptasensor with enhanced cathodic photocurrent response is proposed for sensitive detection of prostate-specific antigen (PSA). The self-powered system is constructed by a cadmium sulfide-sensitized zinc oxide nanorod array (CdS/ZnO NA) as a photoanode with an iodide-doped bismuth oxychloride flower-array (I:BiOCI) as a photocathode, which can generate the electrical output under visible light irradiation with no external power supply. In addition, the p-type semiconductor I:BiOCI with a special internal electric field between the iodide ion layer and the [BiO] layer could increase the cathodic photocurrent response by facilitating the separation of electron/hole pairs under visible light excitation.

[Predictive Markers for Treating Efficacy of PD-1/PD-L1 Inhibitors in Patients with Lung Cancer: A Review of the 18th World Conference on Lung Cancer].

Programmed cell death-1 (PD-1)/programmed cell death-ligand 1 (PD-L1) checkpoint blockades have dramatically changed the treatment of non-small cell lung cancer (NSCLC). But we still have no definite biomarkers that may predict the efficacy of treatment by PD-1/PD-L1 inhibitors. In the 18th World Conference on Lung Cancer, the biomarkers that may predict the efficacy of treatment by PD-1/PD-L1 inhibitors in patients with lung cancer has been a popular topic, and it has huge potential in the future.

Prevalence, awareness, treatment and control of diabetes mellitus among middle-aged and elderly people in a rural Chinese population: A cross-sectional study.

Diabetes mellitus ranks high on the international health agenda as a global pandemic and as a threat to human health and global economies. A total of 10851 participants aged over 40 years were included in the cross-sectional analysis. This observational study analyzed the prevalence of diabetes mellitus and the awareness, treatment and glycemic control of diabetes in a rural Chinese population.

TNF-α and IL10 polymorphisms interaction increases the risk of ankylosing spondylitis in Chinese Han population.

Aims: The target of this article was to reveal the role of tumor necrosis factors α (TNF-α) and Interleukin-10 (IL10) gene polymorphisms in ankylosing spondylitis (AS) development and explore the interaction between these two gene polymorphisms.

Methods: The genotyping of gene polymorphims was conducted using ABI Taqman assay method in 84 AS patients and 92 healthy people. Hardy-Weinberg equilibrium (HWE) was checked in the control group and the genotypes and alleles difference were compared with χ(2) test.

Hyperreactio luteinalis after delivery: a case report and literature review.

Hyperreactio luteinalis (HL), characterized by bilateral functional multicystic ovarian enlargement during pregnancy and puerperium, mostly occurs in third trimester. As a rare benign disease, HL is usually self-limited. However, some cases are dignosed by unnecessary operation.

Tumor necrosis factor-alpha gene -308G > A polymorphism alters the risk of hepatocellular carcinoma in a Han Chinese population.

Background: The aim of the present study was to evaluate the influence of tumor necrosis factor-alpha (TNF-α) -308 G > A polymorphism on hepatocellular carcinoma (HCC) risk.

Methods: The present case-control study was conducted in a Han Chinese population consisting of 753 HCC patients and 760 controls from May 2010 to March 2013. The -308 TNF-a promoter polymorphisms were detected.

Removal of maxillary sinus metallic foreign body like a hand sewing needle by magnetic iron.

Metallic foreign bodies are rarely found in the maxillary sinus, and usually they have a dental origin. Two main surgical app-roaches are currently used for the removal of foreign bodies in the maxillary sinus: the bone flap and the endoscopic sinus tech-niques. However, the treatment is not only surgical removal.

The role of the p38 MAPK signaling pathway in high glucose-induced epithelial-mesenchymal transition of cultured human renal tubular epithelial cells.

Background: Epithelial-mesenchymal transition of tubular epithelial cells, which is characterized by a loss of epithelial cell characteristics and a gain of ECM-producing myofibroblast characteristics, is an essential mechanism that is involved in tubulointerstitial fibrosis, an important component of the renal injury that is associated with diabetic nephropathy. Under diabetic conditions, p38 MAPK activation has been reported in glomeruli and mesangial cells; however, studies on p38 MAPK in TECs are lacking. In this study, the role of p38 MAPK in AP-1 activation and in the EMT in the human proximal tubular epithelial cell line (HK-2) under high glucose concentration conditions is investigated.

[ID4 promoter methylation in acute myeloid leukemia].

Objective of this study was to investigate the ID4 gene methylation status in patients with acute myeloid leukemia (AML). Methylation-specific PCR (MS-PCR) was used to detect the promoter methylation status of ID4 gene in bone marrow samples from 46 AML patients with different subtypes and stage of disease and from 10 patients with iron deficiency anemia (IDA) as a control. The results showed that ID4 gene in bone marrow of IDA patients was completely non-methylated, while ID4 gene methylation was found in 39 out of 46 AML patients (positive rate 84.

[Study on mechanism of Quyujiedu method in treating endometriosis of stasis-toxic syndrome type].

Objective: To observe the mechanism of Quyujiedu (QYJD, a method for removing stasis and detoxicating) in treating endometriosis of stasis-toxic syndrome type.

Methods: Clinical study: Sixty patients were randomly divided into two groups, the treated group treated with QYJD and the control group treated with Danazol. The changes of clinical symptoms, physical signs, pregnancy rate, as well as levels of interleukin-1 (IL-1), interleukin-6 (IL-6) and endometrial antibody (EMAb) in them before and after treatment were observed.
