A novel Schirmer strip-based tear matrix metalloproteinase measurement in dry eye evaluation.

Purpose: The diagnosis and evaluation of dry eye require easy-to-use, precise, and consistent tools in clinical setting. Matrix metalloproteinase 9 (MMP-9) has been proven to be a reliable indicator of dry eye inflammation. The aim of this study is to establish an Eu-time resolved fluorescence immunochromatography (Eu-TRFICO) method for quantitative detection of MMP-9 in human tear based upon widely used Schirmer strips.

The causal relationship between rheumatoid arthritis and interstitial lung disease in East Asian population: A two-sample Mendelian randomization study.

To investigate the causal relationship between rheumatoid arthritis (RA) and interstitial lung disease (ILD) in the East Asian population, we utilized Mendelian randomization (MR). Publicly available summarized data from genome-wide association studies on RA (4199 cases and 208,254 controls), and the data on ILD (1046 cases and 176,974 controls) were obtained from BioBank Japan. Eligible single nucleotide polymorphisms from East Asian populations were obtained from genome-wide association studies as instrumental variables, and 11 RA-related single nucleotide polymorphisms (P < 5 × 10-8) were selected as instrumental variables.

Identification of the length and location of the A1 pulley combining palpation technique with palm landmarks: a cadaveric study.

Through anatomical morphology, to accumulate the relevant parameters of the A1 pulley of each adult finger. A total of 100 fingers were selected, dissected layer by layer, and the A1 pulley and neurovascular of each finger were observed. Measure the length of the A1 pulley, the distance between the needle knife insertion point and the proximal edge of A1 pulley, and the nerves and blood vessels on both sides.

Development of high-performance point-of-care aqueous VEGF detection system and proof-of-concept validation in RVO patients.

Objectives: To develop a sensitive point-of-care testing (POCT) aqueous vascular endothelial growth factor (VEGF) detection system, and assess its role for predicting the response to anti-VEGF treatment in macular edema secondary to retinal vein occlusion (RVO-ME) patients.

Methods: An automatic point-of-care aqueous humor Magnetic Particle Chemiluminescence Enzyme Immuno-Assay (MPCLEIA) VEGF detection system was developed. The predictive values of aqueous cytokine levels, in combination with imaging parameters, on anatomical treatment response (ATR, the relative central macular thickness change [ΔCMT/bl-CMT]) were analyzed.

Morphometric study of percutaneous A1 pulley of thumb release.

Through anatomy, microscope, histopathology, and simulating needle knife operation on specimens, to accumulate the relevant parameters of the A1 pulley of thumb, and to provide an anatomical evidence for the needle knife therapy of stenosing flexor tenosynovitis. A total of 20 fingers were selected from 20 intact adult upper limb specimens, a small amount of emerald green waterproof dye was injected from the needle insertion point, dissected layer by layer, and the A1 pulley and neurovascular bundle were observed. Observe the loosening of the thumb A1 pulley after 5 and 10 times of simulated needle knife cutting on the specimen; observe the relationship between the needle knife entry point and the A1 pulley under the thumb extension and abduction, and the thumb extension neutral position respectively; further observe the histological characteristics, and the relationship between needle entry point and A1 pulley by microscope.

A study of 285 cases of cranial vault suture closure in Chinese adults.

Purpose: To examine the presence and characteristics of cranial vault suture closure in Chinese adults and to explore whether craniosacral therapy (CST) manipulation is rational from the anatomical perspective.

Methods: Anthropological non-metric observation and craniometry were used to study 285 dry skull specimens of Chinese adults.

Results: A total of 91 specimens with closed extracranial sutures were observed, with an occurrence rate of 31.

[Problems of acupoint injection therapy].

There are a large number of clinical reports that acupoint injection therapy is effective, but there are still some basic problems that have not been effectively resolved, such as the type, dosage, concentration and compatibility of acupoint injection drugs. This article analyzes and discusses the problems of acupoint injection therapy in five aspects: the effect of acupoint injection on local tissues, the study of mechanism, the best treatment plan and advantages, and the similarities and differences with local injection therapy.

Why some donors are more willing to donate platelets? ----a qualitative study on 25 regular platelet donors in Guangzhou, China.

Background: Since 1998, China has gradually moved toward voluntary uncompensated blood donation. In some cities, the shortage of platelets has been noticeably severe. Mutual assistance that collects blood from one's family and social networks is a potential solution.

The use of a retrievable self-expanding stent in treating childhood benign esophageal strictures.

Background/purpose: Esophageal stenting is a popular form of treatment of esophageal strictures in adults but is not widely used in children. The aim of the current study was to investigate whether esophageal stents could be used safely and effectively in the treatment of esophageal stenosis in children.

Methods: Covered retrievable expandable nitinol stents were placed in 8 children with corrosive esophageal stenosis.
