1.First report of seroprevalence of Toxoplasma gondii in domestic geese in Hunan province, subtropical China
Tropical Biomedicine 2016;33(2):366-369
. Toxoplasma gondii is one of the most common protozoan parasites with widespread
distribution globally. However, little information is available about the seroprevalence of T.
gondii infection in geese (Anser domestica) in China. In the present study, the seroprevalence
of T. gondii in geese were investigated in Hunan province, China. A total of 900 serum
samples were collected from ten administrative regions in Hunan province, China, and assayed
for T. gondii antibodies by Indirect Haemagglutination (IHA) test. Overall, 21.1% of the
animals were positive for T. gondii antibodies. The results of the present survey indicated the
presence of T. gondii infection in geese in Hunan province, China. Therefore, it is important
to execute integrated control strategies and measures to prevent and control T. gondii
infection in geese in this province. This is the first report seroprevalence of T. gondii in geese
in Hunan province, China.

OBJE CTIVE To mine and analyze t he cardiac adverse drug reaction (ADR)signals induced by febuxostat in post-marketing experience ,and to provide reference for rational drug use in clinic. METHODS Reporting odds ratio (ROR) method was used to mine the ADR signals induced by febuxostat from the FDA Adverse Event Reporting System during the first quarter of 2009 to the fourth quarter of 2020;the information of cardiac disease signals was counted and analyzed. RESULTS A total of 209 ADR signals were detected in 8 282 adverse drug event (ADE)reports with febuxostat as the primary suspected drug , involving 27 cardiac signals and 754 ADE reports. The most reported signals were symptoms (262 reports),including dizziness , oedema peripheral,chest pain ,palpitations and gravitational oedema and so on ,followed by coronary atherosclerotic heart disease signal,heart failure signal ,arrhythmia signal ,sudden cardiac death signal (233,157,90,12 reports,respectively). More than half of the signals were mentioned in the drug instructions ,while the unmentioned signals were mainly kinds of cardiac failure , arrhythmia and extrasystoles ,etc. The patients with cardiac ADEs who received febuxostat were more male than female ,and the age was 60 and over ;the drug dosage was mostly 40 mg/d or 80 mg/d as recommended in the drug instructions ,and cardiac ADEs mostly occurred within 1 month of medication. CONCLUSIONS Routine attention should be paid to the cardiac safety of febuxostat during medication ,further evaluation and validation of febuxostat-induced cardiac ADR signals are still needed.

Clinics in Shoulder and Elbow 2023;26(4):423-437
Background:
Radiofrequency has seen an increase in use in orthopedics including cartilage lesion debridement in the hip and knee as well as many applications in arthroscopic shoulder surgery. The purpose of this systematic review is to evaluate the safety and usage of radiofrequency in the shoulder.
Methods:
This systematic review was registered with PROSPERO (international registry) and followed the preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P) guidelines. Embase and PubMed were searched using: “shoulder,” “rotator cuff,” “biceps,” “acromion” AND “monopolar,” “bipolar,” “ablation,” “coblation,” and “radiofrequency ablation.” The title and abstract review were performed independently. Any discrepancies were addressed through open discussion.
Results:
A total of 63 studies were included. Radiofrequency is currently utilized in impingement syndrome, fracture fixation, instability, nerve injury, adhesive capsulitis, postoperative stiffness, and rotator cuff disease. Adverse events, namely superficial burns, are limited to case reports and case series, with higher-level evidence demonstrating safe use when used below the temperature threshold. Bipolar radiofrequency may decrease operative time and decrease the cost per case.
Conclusions
Shoulder radiofrequency has a wide scope of application in various shoulder pathologies. Shoulder radiofrequency is safe; however, requires practitioners to be cognizant of the potential for thermal burn injuries. Bipolar radiofrequency may represent a more efficacious and economic treatment modality. Safety precautions have been executed by institutions to cut down patient complications from shoulder radiofrequency. Future research is required to determine what measures can be taken to further minimize the risk of thermal burns.

OBJECTIVE: To predict the anti-inflammatory active components and mechanism of couplet medicine of Notopterygium incisum-Angelica pubescens. METHODS: According to the principle of oral bioavailability≥30% and drug- likeness≥0.18, active components of N. incisum and A. pubescens were screened; TCMSP was used to predict and screen the potential target of them. Using “Anti-inflammatory” as keyword, inflammatory related target genes were retrieved from human gene database Genecards. Common target was screened by mapping the target genes of active ingredients from couplet medicine of N. incisum-A. pubescens. The active ingredient-target network was established by using Cytoscape 3.5.1 software. The screened targets were used to construct the target protein interaction (PPI) network on the STRING V 10.5 platform. Its anti-inflammatory mechanism was studied by KEGG signaling pathway and GO biological enrichment analysis. RESULTS: Totally 15 active components such as coumarin, beta-sitosterol, ammidin, nodakenin were selected from couplet medicine of N. incisum-A. pubescens. Acting on 49 targets such as transcription factor AP-1, PI3-kinase subunit gamma, estrogen receptor, they mainly involved 19 signaling pathways such as hepatitis B and cell apoptosis, and were involved in 47 biological processes such as regulating inflammatory response and prostaglandin biosynthesis. CONCLUSIONS: The anti-inflammatory mechanism of active components of couplet medicine of N. incisum-A. pubescens on multi-target, multi-channel and multi-biological processes is predicted, and it points out the direction for further anti-inflammatory mechanism study.

Objective:
To evaluate the anti-fatigue effects of different extracts from Cistanche tubulosa (Schenk) Wight (C. tubulosa, Rou Cong Rong), focusing on central and exercise-induced fatigue in mice. This study investigated the pharmacological effects of the total oligosaccharides, polysaccharides, and phenylethanoid glycosides (CPhGs) extracted from C. tubulosa.
Methods:
Models of sleep deprivation and forced swimming fatigue were established to simulate central and exercise-induced fatigue. The mice were treated with different extracts of C. tubulosa, and their effects were assessed using behavioral tests to measure exercise capacity, learning, and memory function. Biochemical analyses were performed to evaluate the changes in serum and brain neurotransmitter levels, liver and muscle glycogen storage, and various fatigue-related biomarkers.
Results:
This study found that treatment with C. tubulosa extract improved exercise capacity, learning, and memory in mice. Total oligosaccharides from C. tubulosa enhanced adrenocorticotropic hormone, cholinesterase, and thyroid-stimulating hormone levels, reduced cortisol levels in central fatigue models, and ameliorated biochemical markers of exercise-induced fatigue, including lowering lactic acid, blood urea nitrogen, and malondialdehyde levels. Among the tested extracts, the total oligosaccharides showed the most comprehensive anti-fatigue effects.
Conclusion
The anti-fatigue effects of C. tubulosa, particularly those of its total oligosaccharides, are pronounced in both central and exercise-induced fatigue. These effects are mediated by the regulation of neurotransmitter levels, enhancement of glycogen storage, and improvement of antioxidant enzyme activity, suggesting potential therapeutic benefits in fatigue-related conditions.

OBJECTIVETo observe the effect of Coptidis Rhizoma (CR) on hemolysis and antioxidant system of normal mice and its impact on the functions, while evaluating the oxidation reduction property of CR and berberine.
METHODIn the whole animal experiment, normal mice were orally administered with CR at the dose of 1.2 g x kg(-1) for three days. Their blood were collected to detect the hemoglobin in plasma, the content of serum bilirubin, the number of peripheral blood reticulocytes, the T-AOC in whole blood, measure the contents of glucose-6-phosphate-dehydrogenase (G6PD), superoxide dismutase (SOD), glutathione (GSH) and malondialdehyde (MDA) of RBC membrane, determine the activity of Na(+)-K(+)-ATPase, Ca(2+)-Mg(2+)-ATPase, fluidity, and observe its impact on the liquidity and deformability of RBCs. According to the electrical and biochemical experiment, the voltammetric behaviors of CR and berberine on glassy carbon electrode were evaluated using cyclic voltammetry. In the RBC in vitro experiment, the impact of Coptidis Rhizoma on autoxidation hemolysis rate of RBCs of normal mice was observed.
RESULTThere was no significant effect on hemoglobin, serum bilirubin, and reticulocyte count in normal mice administrated with CR at the dose of 1.2 g x kg(-1), and so is on RBC membrane SOD, G6PD, MDA, GSH and whole blood T-AOC activity. In addition, CR had also no significant effect on Na(+)-K(+)-ATPase, Ca(2+)-Mg(2+)-ATPase activity, and no notable impact on the fluidity and deformability of RBCs. There were two oxidation peaks at -0.27 V and 0.60 V induced by CR and one oxidation peak induced by berberine at 0.56 V, with no reduction peak at fly-back. CR could significantly inhibit oxidative hemolysis in RBCs at the dose of 0.125-2 g x L(-1) in vitro.
CONCLUSIONThe normal dose of Coptidis Rhizoma can not cause hemolysis of RBC, and also can not change antioxidant system and functions of RBC, CR and berberine show antioxidant (reducing) properties.

Platelet to lymphocyte ratio (PLR) is a prognostic marker in human hepatocellular carcinoma (HCC) however, its utility in canine HCC has not been explored. The aim of the study was to determine if PLR could predict survival outcomes in 42 dogs with HCC. PLR was not a significant predictive factor (p = 0.15) but lymphopenia alone was significantly correlated with a reduced probability of survival (p = 0.024). Further studies are needed to evaluate if peripheral lymphocyte count mirrors that of the tumor microenvironment in canine HCC.

Background/Aims:
The pathophysiology of jackhammer esophagus (JE) remains unknown but may be related to gastroesophageal reflux disease or medication use. We aim to determine if pathologic acid exposure or the use of specific classes of medications (based on the mechanism of action) is associated with JE.
Methods:
High-resolution manometry (HRM) studies from November 2013 to March 2019 with a diagnosis of JE were identified and compared to symptomatic control patients with normal HRM. Esophageal acid exposure and medication use were compared between groups. Multivariate regression analysis was performed to look for predictors of mean distal contractile integral.
Results:
Forty-two JE and 127 control patients were included in the study. Twenty-two (52%) JE and 82 (65%) control patients underwent both HRM and ambulatory pH monitoring. Two (9%) JE patients and 14 (17%) of controls had evidence of abnormal acid exposure (DeMeester score > 14.7); this difference was not significant (P = 0.290). Thirty-six (86%) JE and 127 (100%) control patients had complete medication lists. Significantly more JE patients were on long-acting beta agonists (LABA) (JE = 5, control = 4; P = 0.026) and calcium channel blockers (CCB) (JE = 5, control = 3; P = 0.014). Regular opioids (β = 0.298, P = 0.042), CCB (β = 0.308, P = 0.035), and inhaled anticholinergics (β = 0.361, P = 0.049) predicted mean distal contractile integral (R2 = 0.082, F = 4.8; P = 0.003).
Conclusions
Pathologic acid exposure does not appear to be associated with JE. JE patients had increased CCB and LABA use. The unexpected finding of increased LABA use warrants more investigation and may provide support for a cholinergic etiology of JE.
