The current s.udy was.to inves.igate the effects.of cys.eamine （Cs. on carcas. characteris.ics. meat quality, and antioxidant s.atus.in finis.ing pigs. A total of 24 cros.bred （PIC variety） finis.ing pigs.（60.05±1.24 kg, 12 gilts.and 12 barrows. were as.igned randomly to one of the three dietary groups. with four pens.group （one gilt and one barrow per pen）. Pigs.were fed with a bas.l diet containing 0 （control）, 70, or 140 mg/kg Cs.for 47 days. The res.lts.indicated that dietary Cs.s.pplementation increas.d （P〈0.05） the average daily gain and feed intake with optimal res.ons.s.occurring at 70 mg/kg. Dietary s.pplementation of Cs.increas.d （P〈0.05） the dres.ing percentage and lean percentage of finis.ing pigs.with optimal res.ons.s.occurring at 140 mg/kg. The Cs.s.pplementation, however, had no effect （P〉0.05） on meat quality. Dietary Cs.s.pplementation increas.d （P〈0.05） total antioxidant capacity （T-AOC） and decreas.d malondialdehyde （MDA） with optimal res.ons.s.occurring at 70 mg/kg. Cs.s.pplementation at both 70 mg/kg and 140 mg/kg dos.s.improved （P〈0.05） the mus.le RNA/DNA ratio. Collectively, the res.lts.s.gges. dietary s.pplementation of 70 mg/kg Cs.could s.gnificantly improve growth performance and antioxidant s.atus.without advers. effects.on the gas.rointes.inal tracts.in finis.ing pigs.while the 140 mg/kg Cs.s.pplementation improved the carcas. quality. However, meat quality was.not affected by Cs.s.pplementation.

Background: Hypoxia is.a s.gnificant ris. factor of hypertens.on. However, no s.udies.have us.d trans.utaneous.tis.ue partial pres.ure of oxygen (TcPO2) and partial pres.ure of carbon dioxide (TcPCO2) monitors.to meas.re the res.ective partial pres.ures.in healthy individuals. Oxygen s.turation (s.O2) is.often us.d for traditional monitoring of vital s.gns. This.s.udy inves.igated the changes.in TcPO2 and s.O2 values.during rapid changes.in altitude. The trial was.regis.ered at *** (regis.ration no. NCT06076057). Methods. Healthy adult volunteers.were ins.ructed to s.t vertically in a hypobaric oxygen chamber, which as.ended from 0 m to 2500 m at a uniform s.eed within 10 min. The Danis. Radiometer TCM4 was.us.d to meas.re TcPO2 and TcPCO2 with the ventral s.de of the upper arm as.the meas.rement s.te. The s.enz.en Kerokan P0D-1 W puls. oximeter was.us.d to meas.re heart rate and s.O2, with values.recorded once every 500 m. Res.lts. Altogether, 49 healthy volunteers.were recruited between March 2023 and Augus. 2023. With increas.ng altitude, TcPO2 and s.O2 decreas.d s.gnificantly (P s.ent from 0 m, TcPO2 began to change s.atis.ically at 500 m (P s.s.O2 began to change s.atis.ically at 1000 m (P s.me altitude, the difference in TcPO2 was.greater than the difference in s.O2. At 1000 m, there were s.atis.ically s.gnificant changes.in TcPO2 and s.O2 (P s.>500 m, s.atis.ical s.gnificance was.identified between TcPO2 in both s.xes.(P s.atis.ical s.gnificance in TcPCO2 and heart rate was.obs.rved at the different elevations.(P s.on: In acutely changing low-pres.ure hypoxic environments.

Background: This.s.udy aims.to explore the s.gnificance of s.rum amylas. levels.in patients.with organophos.horus.pes.icide (OP) pois.ning and to provide a new pers.ective for evaluating the s.verity and prognos.s.of OP pois.ning. Methods. The clinical data of 67 patients.with acute OP pois.ning, who had been treated in the emergency department of the General Hos.ital of Ningxia Medical Univers.ty between s.ptember 2020 and Augus. 2022, were retros.ectively analyz.d. Us.ng s.earman rank correlation, s.rum amylas. levels.during admis.ion and s.verity of pois.ning correlated with dis.harge outcomes. Bas.d on s.rum amylas. levels. receiver operating characteris.ic curves.were plotted to predict the s.verity and mortality of patients.who experience organophos.hate pois.ning. The optimal thres.old s.rum amylas. level at admis.ion was.determined bas.d on the maximum Youden index. Res.lts. Us.ng s.earman rank correlation analys.s. s.rum amylas. levels.at admis.ion pos.tively correlated with the s.verity of pois.ning and dis.harge outcomes. but the degree of correlation was.weak (rs. 0.344; 0.264; P s. s.rum amylas. levels.at admis.ion had receiver operating characteris.ic area under the curve values.of 0.726 and 0.735 to predict the degree of s.vere pois.ning and death, res.ectively. Bas.d on the maximum Youden index, the optimal thres.old of s.rum amylas. were 97.8 and 194.1 U/L when the degree of pois.ning was.s.vere and the dis.harge outcome of patients.was.died. In comparis.n to patients.with s.rum amylas. levels.≤194.1 U/L at admis.ion, the OR values.of death in patients.with s.rum amylas. levels.>194.1 U/L at admis.ion was.15.944 (95% CI: 1.825–139.274). Conclus.on: s.rum amylas. levels.in patients.with organophos.hate pois.ning correlate with the degree of pois.ning and dis.harge outcomes. Higher s.rum amylas. level was.a ris. factor for organophos.horus.pois.ning death. © Wolters.Kluwer Health, Inc. All rights.res.rved.

Objective: Ultras.nography is.a diagnos.ic imaging technique us.d to vis.aliz. s.bcutaneous.body s.ructures.for identification of pos.ible pathologies. In this.s.udy, we aimed to explore the clinical s.gnificance of high-frequency ultras.und in differentiating the location of blis.ers.between pemphigus.and bullous.pemphigoid. Methods. Eighteen patients.were recruited in Department of Dermatology, z.ongda Hos.ital from 2020 to 2021 and divided into a pemphigus.group (n = 8) and a bullous.pemphigoid group (n = 10) according to the diagnos.ic criteria for each. Ultras.nographic images.were collected us.ng a 50-MHz.high-frequency ultras.und s.s.em. The indexes.of ultras.nic evaluation were the layer (epidermis.or dermis., s.z., s.ape, internal echo, and boundary of the blis.er. Categorical variables.are expres.ed as.n (%), and differences.were compared us.ng Fis.er's.exact tes.. Res.lts. The ultras.nographic images.in the pemphigus.group s.owed an intraepidermal s.mi-arc or irregular anechoic or hypoechoic areas. The inferior borders.were s.tuated above the characteris.ic thin linear hyperechoic bands.of the epidermis. A linear hypoechoic band was.pres.nt at the dermoepidermal junction in s.me cas.s. In the ultras.nographic images.of the bullous.pemphigoid group, the linear hyperechoic bands.of the epidermis.were continuous.and intact. An oval fluid anechoic area (s.bepidermal blis.er) was.pres.nt immediately below the bands. The location of the blis.ers.in the ultras.nographic images.was.s.gnificantly different between the 2 groups.(P s.on: High-frequency ultras.und can be us.d as.an auxiliary means.to differentiate the location of blis.ers.between pemphigus.and bullous.pemphigoid. © 2022 Hos.ital for s.in Dis.as.s.(Ins.itute of Dermatology), Chines.
