The efficacy and safety of Chinese massage in the treatment of acute mastitis: A protocol for systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: The incidence of acute mastitis (AM) in lactating women has been increasing year by year. If there is no timely and appropriate treatment, AM may develop into mammary abscess and septicemia. This special situation has aroused social attention. Chinese massage has been widely used in the treatment of AM in recent years, but there is no systematic review of the effect of Chinese massage on AM. We plan to explore the efficacy and safety of Chinese massage in the treatment of AM. METHODS: We will use a computer to search the following 8 electronic databases (PubMed, Web of Science, Cochrane, Embase, Sinomed, China National Knowledge Infrastructure, Chongqing VIP Information, WanFang Data) on November 30, 2021. Randomized controlled trials (RCT) of Chinese massage therapy for AM were screened. Primary outcome measure: overall clinical response rate, breast pain score. Secondary outcome measures: milk secretion, temperature, mass size and time to resolution, White blood cell count, C-reactive protein, and the incidence of adverse reactions. According to the inclusion criteria and exclusion criteria, the included literature will be independently evaluated by two researchers using the RCT bias risk assessment tool in the Cochrane evaluation manual Handbook5.4, and meta-analysis will be performed by RevMan5.4 software. Funnel plots were used to analyze whether the study had publication bias. RESULTS: We will evaluate the clinical effect of Chinese massage therapy on AM based on RCTs. CONCLUSION: This study will provide evidence-based evidence for the effectiveness and safety of Chinese massage in the treatment of AM. PROTOCOL REGISTRATION NUMBER: INPLASY2021120019.

Anti-Tumor Effects of Melittin and Its Potential Applications in Clinic.

Melittin, a major component of bee venom, is a water-soluble toxic peptide of which a various biological effects have been identified to be useful in anti-tumor therapy. In addition, Melittin also has anti-parasitic, anti-bacterial, anti-viral, and anti-inflammatory activities. Therefore, it is a very attractive therapeutic candidate for human diseases. However, melittin induces extensive hemolysis, a severe side effect that dampens its future development and clinical application. Thus, studies of melittin derivatives and new drug delivery systems have been conducted to explore approaches for optimizing the efficacy of this compound, while reducing its toxicity. A number of reviews have focused on each side, respectively. In this review, we summarize the research progress on the anti-tumor effects of melittin and its derivatives, and discuss its future potential clinical applications.

Correlations between the optic nerve head morphology and ocular biometrics in highly myopic eyes.

AIM: To analyze peripapillary atrophy ß/γ zone (PPA-ß/γ) and the optic disc ovality index, and to assess their associations with the axial length (AL), refractive error, best corrected visual acuity (BCVA), choroidal thickness (CT), and age in highly myopic eyes. METHODS: This was a retrospective observational case series. The study included 667 patients consecutively examined for highly myopic eyes [spherical equivalent ≤-6.0 diopters (D) and AL≥26 mm] with or without myopic retinopathy. Each patient went through a comprehensive ophthalmological examination that included spectral domain optical coherence tomography (SD-OCT) of the macula, A-mode ultrasonography, and a cycloplegic refraction test. The ovality index and PPA-ß/γ area were measured from optic disc photographs. RESULTS: A significant association was seen between PPA-ß/γ area and the ovality index (P=0.000, r=-0.232). The PPA-ß/γ area increased significantly with a longer AL, older age, worse BCVA, higher refractive error, and thinner choroid (P<0.01). The oval disc was significantly correlated with a longer AL, older age, worse BCVA, higher refractive error, larger PPA-ß/γ area, and thinner choroid (P<0.01). CONCLUSION: The PPA-ß/γ zone and ovality index in highly myopic eyes show distinct associations with the AL, refractive error, BCVA, age, and CT.

[Research advances in immune tolerance of allogeneic cell transplantation in preterm infants].

Preterm infants are a special group, and related severe neurological, respiratory, and digestive disorders have high disability/fatality rates. Allogeneic cell transplantation may be an effective method for the prevention and treatment of these diseases. At present, animal studies have been conducted for allogeneic cell transplantation in the treatment of hypoxic-ischemic encephalopathy, bronchopulmonary dysplasia, and necrotizing enterocolitis. The main difficulty of this technique is graft-versus-host reaction (GVHR), and successful induction of immune tolerance needs to be achieved in order to solve this problem. This article reviews the research advances in immune tolerance of allogeneic cell transplantation in preterm infants.
