Serological characteristics and clinical implications of IgG subclasses in visceral leishmaniasis.

Objectives: Visceral leishmaniasis (VL) represents the most severe form of Leishmaniasis infection, often resulting in fatality without timely treatment. Previous studies have found that immunosuppression increases the risk of VL disease progression and mortality, and the total immunoglobulin G (IgG) levels in peripheral blood vary before and after treatment. However, the distinct levels and roles of IgG subclasses in VL have not been documented yet.

Measurement-Device-Independent Quantum Key Distribution Based on Decoherence-Free Subspaces with Logical Bell State Analyzer.

Measurement-device-independent quantum key distribution (MDI-QKD) enables two legitimate users to generate shared information-theoretic secure keys with immunity to all detector side attacks. However, the original proposal using polarization encoding is sensitive to polarization rotations stemming from birefringence in fibers or misalignment. To overcome this problem, here we propose a robust QKD protocol without detector vulnerabilities based on decoherence-free subspaces using polarization-entangled photon pairs.

Establishing a predictive model for aspirin resistance in elderly Chinese patients with chronic cardiovascular disease.

Background: Resistance to anti-platelet therapy is detrimental to patients. Our aim was to establish a predictive model for aspirin resistance to identify high-risk patients and to propose appropriate intervention.

Methods: Elderly patients (n = 1130) with stable chronic coronary heart disease who were taking aspirin (75 mg) for > 2 months were included.

[The experimental study of simvastatin on improving aspirin resistance in diabetic rats].

Objective: The purpose of the present study was to investigate the effects of the combination of aspirin, simvastatin in diabetic rat on platelet function.

Methods: Eight-week-old male Wistar rats were selected and randomly divided into diabetic group (=48) and normal control group (=48). Diabetic rats were injected with 1% STZ (65mg/kg, dissolved in 0.

Correlation between sex hormone levels and obesity in the elderly male.

Objective: To investigate the levels of sex hormones and androgen receptor (AR) in elderly male patients and to explore a possible correlation with obesity.

Methods: The cross-sectional study included 314 Elderly males (age ≥ 65 year). Of these subjects, 104 were healthy (age range 65-92 year; mean 71.

[Analysis of Liqi decoction for treatment of false intestinal obstruction caused by retroperitoneal hematoma].

Objective: To study the efficiency of Liqi decoction on false intestinal obstruction caused by retroperitoneal hematoma.

Methods: Seventy-five patients were randomly divided into two groups involving Liqi groups and control group. In Liqi group, therer were 45 patients including 28 males and 17 females with an average age of (41.
