Objective:To investigate the effects of budesonide on blood gas and inflammation indexes in patients with chronic obstructive pulmonary disease(COPD)during remission.Methods:Fifty-one patients with COPD in remission,admitted to Zhongshan Hospital of Dalian University from July 2021 to December 2022,were selected and divided into two groups based on a randomized numerical table method.The control group(25 cases)received budesonide formoterol treatment,while the observation group(26 cases)received budesonide geforce treatment.Various indexes,including clinical efficacy,blood gas indexes,inflammation indexes,St.George’s Respiratory Questionnaire(SGRQ)scores,Chronic Obstructive Pulmonary Disease Assessment Test(CAT)scores,and 6-minute Walking Distance Test(6MWD)results,were compared between the two groups.Results:After 21 days of treatment,the total clinical effectiveness rate of the observation group was higher than that of the control group,with a statistically significant difference(P<0.05).Post-treatment,the PaO2 level and pH value in both groups were higher,and the PaCO_(2) level was lower compared to pre-treatment levels.The observation group showed better improvements in these indicators than the control group,with statistically significant differences(P<0.05).SGRQ and CAT scores for both groups were lower post-treatment,with the observation group scoring lower than the control group.Additionally,the 6MWD results were farther for both groups post-treatment,with the observation group achieving greater distances than the control group,with statistically significant differences(P<0.05).Conclusion:Budesonide can effectively improve blood gas indexes in patients with COPD in remission,alleviate related clinical symptoms,reduce inflammatory responses,and promote patient recovery.The treatment efficacy is significant.

The influences of SE infection on layers' production performance,egg quality and blood biochemical indicators

Background： Salmonella enterica serovar Enteritidis （SE）, as a major cause of foodborn illness, infects humans mainly through the egg. However, the symptom of laying hens usually is not typical and hard to diagnosis. In the present study, it is studied that the influences of SE infection on layers＇ performance, egg quality and blood biochemical indicators. It will help us to improve the strategy to control SE infection in commercial layers. One hundred layers at 20 wk of age were divided into 2 groups, 60 hens for experiment and others for control. The experiment group was fed with the dosage of 108 CFU SE per hen. The specific PCR was used to detect the deposition of SE. On the 8 d after SE infection, 10 hens from the control group and 30 hens from the experimenta group were slaughtered to detect the SE colonization. The production performance, egg quality and blood biochemical indices were also analyzed. Results： The results showed that the colonization rate of SE was highest in caecum contents （55.17%） and lowest in vagina （17.24%）. For the eggs the detection rate of SE was highest on the eggshell （80.00%） and lowest in yolk （18.81%）. SE infection had no significant influence on production performance and egg qualities （P 〉 0.05）. The difference of laying rate between the experimental and control groups was less than 0.30%, and both were approximately equal to 82.00%. The blood analysis showed that the aspartic aminotransferase （AST） and alanine aminotransferase （ALT） of experimental group was significantly higher than those of control group （P 〈 0.05）. For experimental and control groups AST values were 236.22 U/I and 211.84 U/I respectively, and ALT values were 32.19 U/I and 24.55 U/I. All of coefficients were less than 20%. The colonization of SE in organs increases the enzyme activities of AST and ALT in blood. Conclusions： SE in feed could invade the oviduct and infect the forming eggs. It significantly increased the concentration of ALT and AST in blood. However,SE infection was hard to be observed from the appearances of layer and egg. It might be a dangerous risk to human health.

Plasma urea nitrogen （PUN） of group B and C were higher than group A significantly （P〈0.05 ） ;Total protein （ TP）, Plasma albumin （ALB） and Plasma total amino acid were no significant difference among the other 3 groups （P〉0.05 ）. [Conclusion] So, the milk-replacers were available for early-weaned lamb.

Effects of nursing team communication and collaboration on treatment outcomes in intensive care unit patients with severe pneumonia

BACKGROUND Severe pneumonia is a common severe respiratory infection worldwide,and its treatment is challenging,especially for patients in the intensive care unit(ICU).AIM To explore the effect of communication and collaboration between nursing teams on the treatment outcomes of patients with severe pneumonia in ICU.METHODS We retrospectively analyzed 60 patients with severe pneumonia who were treated at the ICU of the hospital between January 1,2021 and December 31,2023.We compared and analyzed the respiratory mechanical indexes[airway resistance(Raw),mean airway pressure(mPaw),peak pressure(PIP)],blood gas analysis indexes(arterial oxygen saturation,arterial oxygen partial pressure,and oxygenation index),and serum inflammatory factor levels[C-reactive protein(CRP),procalcitonin(PCT),cortisol(COR),and high mobility group protein B1(HMGB1)]of all patients before and after treatment.RESULTS Before treatment,there was no significant difference in respiratory mechanics index and blood gas analysis index between 2 groups(P>0.05).However,after treatment,the respiratory mechanical indexes of patients in both groups were significantly improved,and the improvement of Raw,mPaw,plateau pressure,PIP and other indexes in the combined group after communication and collaboration with the nursing team was significantly better than that in the single care group(P<0.05).The serum CRP and PCT levels of patients were significantly decreased,and the difference was statistically significant compared with that of nursing group alone(P<0.05).The levels of serum COR and HMGB1 before and after treatment were also significantly decreased between the two groups.CONCLUSION The communication and collaboration of the nursing team have a significant positive impact on respiratory mechanics indicators,blood gas analysis indicators and serum inflammatory factor levels in the treatment of severe pneumonia patients in ICU.

Severe hyperlipemia-induced pseudoerythrocytosis - Implication for misdiagnosis and blood transfusion: A case report and literature review

BACKGROUND Severe hyperlipemia(SHLE)has an impact on the results of many kinds of laboratory tests.Complete blood count(CBC)examination by automated blood cell counter(ABCC)is a quick and convenient measurement for screening abnormalities of blood cells that are triggered by various pathogenic insults in disease diagnosis and for monitoring changes in the treatment of existing hematological conditions.However,CBC results are frequently affected by many intrinsic and extrinsic factors from blood samples,such as in the setting of hypergammaglobulinemia and certain anticoagulants.SHLE could also affect CBC results.CASE SUMMARY A 33-year-old Chinese male presented with painful foot numbness and abdominal pain.He was initially misdiagnosed as having a myeloproliferative neoplasm(MPN)because of the marked abnormalities in CBC examination by the ABCC.Morphological evaluation of the bone marrow smears and biopsy showed no evidence of MPN.Gene mutations in Breakpoint cluster regions-Abelson murine leukemia viral oncogene homologue 1(BCR-ABL1),Janus kinase 2(JAK2),calreticulin(CALR),myeloproliferative leukemia virus(MPL),and colony-stimulating factor 3 receptor(CSF3R)were negative.Having noticed the thick chylomicron layer on blood samples and the dramatically fluctuating CBC results,we speculated that the fat droplets formed by shaking the blood samples in the setting of SHLE were mistakenly identified as blood cells due to the limited parameters of ABCC.Therefore,we removed a large part of the chylomicron layer and then reexamined the CBC,and the CBC results,as we expected,differed significantly from that of the sample before the chylomicron layer was removed.These significant differences had been validated by the subsequently repeated laboratory tests by measuring dual blood samples that the chylomicron layer was removed in one sample and was not in another,and comparing the CBC results.Computerized tomography reexamination of the upper abdomen revealed an exudative lesion surrounding his pancreas.After intensive consultation,definitive diagnosis was made as recurrent pancreatitis,hyperlipemia and pseudoerythrocytosis.CONCLUSION SHLE may become a potential cause of misdiagnosis of hyperlipemia-related diseases as MPNs and the resultant mistreatment.It may also lead to the misinterpretation of transfusion indications in patients with hematological disorders who critically need blood transfusion for supportive treatment.

Epidemiological features and dynamic changes in blood biochemical indices for COVID-19 patients in Hebi

BACKGROUND Millions of people have died of coronavirus disease 2019(COVID-19)due to severe acute respiratory syndrome coronavirus 2(SARS-Co V-2)infection,and retrospective studies of the disease in local regions are necessary.AIM To characterize the epidemiological features and dynamic changes in blood biochemical indices for SARS-Co V-2-infected patients in Hebi,a representative city with a large floating population in North China.METHODS From January 25 to February 10,2020,the clinical data of patients who tested positive for SARS-Co V-2 by quantitative real-time polymerase chain reaction in Hebi city(China)were evaluated at admission,and laboratory data for hematologic parameters,inflammatory indices,coagulation function indices,liver function indices,blood lipid indices,renal function indices,myocardial enzyme activities and five blood biochemical markers of immunity were evaluated at admission,upon hospitalization and before discharge.RESULTS Sixteen confirmed COVID-19 patients developed pneumonia but were cured after adequate treatment.Fever and fatigue were the common symptoms.The most common laboratory abnormalities of patients at admission were leukopenia,eosinopenia,decreased percentage of eosinophils,elevated high sensitivity C-reactive protein and fibrinogen levels,hypoalbuminemia,mildly increased aspartate transferase activity and levels of bilirubin,and increased levels ofβ2-microglobulin.Importantly,aggravated liver dysfunction was detected in most patients,which may be partially attributed to virus infection as well as medicinal treatment.CONCLUSION This study provides several potential diagnostic markers and dynamic biochemical indices of disease progression to better prevent,diagnose and treat COVID-19 infection.

Bio-Effect of Rare Earths in RE-High Background Region I. Some Blood Biochemical Indices from Population Resided in Light REE District

The results of biochemical indices in human blood show that there are significant difference in the population mean of these indices between the LREE high region in South Jiangxi, China and the control. In comparison with the normal region, the contents of total serum protein(TSP), albumin(AL), β globulin (β G), glutamic pyruvic transitanase (GPT), serium triglycerides (STG) and immunoglobulin(IgA) are manifested as low, but high cholesterol (CHO) in the LREE high region. These deviations may be related to the REE concentration and composition in food chains, and also are sex dependent. Certain blood indices (such as TSP) of different age groups in the LREE high region indicate that the influence of REE on males is a one way irreversible process while females show a strong ability of restoration.

Distortion product otoacoustic emissions in newborn babies with and without late-term maternal iron deficiency anaemia

Background:Studies on animals have demonstrated that maternal iron deficiency anaemia(IDA)could result in decreased cochlear sensory hair cells and reduced amplitudes of distortion-product otoacoustic emissions(DPOAEs)of young guinea pigs.Thus,it is essential to study the functioning of cochlear hair cells using DPOAEs in human newborn babies with maternal IDA.The current study explores maternal IDA’s effect on DPOAEs in newborn babies.Method:A total of 110 newborn babies with gestational age≥34 weeks were considered and a‘betweensubjects’design was used.The participants were divided into 3 groups-“Normal”(61 babies without maternal IDA),“Mild”(28 babies with mild maternal IDA)and“Moderate”(21 babies with moderate maternal IDA).The cord blood was collected and the DPOAEs were recorded for each baby for a range of frequencies(1 k 8 kHz)and a range of intensities(7040 dB SPL in 10 dB steps).Results:The analysis of both DP-gram and DP input-output(I/O)function showed that there was no significant difference(p>0.05)across the normal,mild,and moderate groups in the overall presence of DPOAEs as well as the amplitude across frequencies or intensities(7040 dB SPL).Also,the overall correlation of RBC indices with DPOAE amplitude across frequencies as well as the slope of the I/O function showed no relationship.Conclusion:The current study concludes that there is no effect of late-term maternal IDA on the DPOAEs of newborn babies.

Effects of Different Padding on Air Quality in Broiler House and Growth Physiological Index of Broilers

[Objective] This study aimed to investigate the effects of different padding on ammonia concentration in broiler house and growth performance and blood indi- cators of broilers. [Method] A total of 480 one-day-old 817 broilers were selected. They were randomly divided into four groups with different paddings, and each group was in triplicate. The weights of broilers and feed were weighed weekly. The growth performance of broilers was determined. On day 30, the ammonia concentra- tions in broiler houses were determined. On day 35, 6 broilers were randomly se- lected from each group, and their vein blood was sampled. In the sampled vein blood, the concentrations of ammonia, glucose, globulin, serum total protein and urea nitrogen were determined. [Result] There were significant differences in ammo- nia concentration among broiler houses laid with different paddings （P〈0.05）. The ammonia concentration in group 1 was significantly lower than those in group 3 and group 4 （P〈0.05）. No significant difference was found in ammonia concentrations in broiler houses between group 2 and group 3 （P〉0.05）. The ammonia concentration in group 4 was significantly higher than those in group1, group 2 and group 3 （,0〈 0.05）. There were also significant differences in blood indicators among different groups （P〈0.05）. The blood ammonia, blood glucose and serum urea nitrogen con- centrations in group 1 were significantly lower than those in other groups （P〈0.05）, the serum total protein concentration was significantly higher than those in group 3 and group 4 （P〈0.05）, and the serum globulin concentration was significantly higher than those in group 2, group 3 and group 4 （P〈0.05）. Significant differences were observed in feed intake, body weight gain and slaughter weight between different groups （P〈0.05）, but there were no significant differences in feed to grain ratio （P〉 0.05）. [Conclusion] Under the experimental conditions, the padding of Chinese medicine residue showed better effect on reducing ammonia concentration in broiler house, which was conducive to play of production potential of broilers.

Effects of Maternal Dietary Energy Restriction on Fat Deposition of Offspring

The study was carried out to investigate the effects of maternal dietary energy restriction on growth performance, serum indices and fat deposition of offspring. A total of 400 female Arbor Acres （AA） broiler breeders were studied. These female birds involved three experimental treatments and a control group with normal dietary energy diets （ND, 11.7 MJ of ME. kgt during the laying）. In treatments 2, 3 and 4, the energies of diets were 20%, 30% and 50% （LD20, LD30 and LD50） lower than those of the control, respectively. The study commenced at the beginning of the laying period when the total egg production reached 5% of the flock. All the broiler offspring were fed the same diets. The results showed that in low energy diets, offspring showed decreased 1-day-old weight, but 49-day-old weight was higher in LD20 diet （P〈0.05）. For offspring during days 1-49, the average daily gain （ADG） in LD20 group and the feed conversion ratio in LD50 group were improved as compared with those of the control （P〈0.05）. Compared with the control, abdominal fat percentage increased in 49-day-old offspring from LD30 diet （P〈0.05）; the fat content of breast muscle in offspring increased in broilers fed low energy diets （P〈0.05）. In 28-day-old offspring from breeders given LD20 and LD50 diets, liver fat percentages were higher compared with ND （P〈0.05）. The subcutaneous fat thickness in 28-day-old offspring from LD50 group and 49-day-old offspring from LD30 group was higher （P〈0.05）. On day 49, the serum cholesterol （CHO） of offspring from breeders fed LD20 diet and serum high-density lipoprotein （HDL） of offspring from breeders fed LD50 diet reduced compared with those of the control （P〈0.05）. In addition, a higher triiodothyronine （T3） content in serum was found in offspring from broiler breeders given LD20 and LD30 diets （P〈0.05）. Serum thyroxine （T4） in offspring significantly decreased with the decrease of diet energy （P〈0.05）. In conclusion, to a certain extent, dietary energy restriction in breeders could improve growth performance and promote lipid metabolism of offspring.

Effect of different sources and levels of iron in the diet of sows on iron status in neonatal pigs

This study was conducted to determine the effects of maternal dietary supplementation of ferrous glycine chelate(Fe-Gly) and ferrous sulfate monohydrate(FeSO_4·H_2O) on the relative organ weight, tissue iron contents, red blood cells(RBC), hemoglobin concentration(HGB) and hematocrit(HCT) in blood, as well as ferritin(Fn), serum iron(SI), and total iron binding capacity(TIBC) in serum of newborn piglets.Forty-five sows(Landrace × Large white, mean parity 3 to 4, no significant differences in BW) were randomly allotted to 9 treatments(n=5 sows/treatment): control(basal diet with no Fe supplementation), the basal diet supplemented with 50, 80, 110 or 140 mg Fe/kg as Fe-Gly, and the basal diet supplemented with 50, 80, 110 or 140 mg Fe/kg as FeSO_4·H_2O.The neonatal piglets(n=45) were used to determine the relative organ weight, tissue iron contents and blood biochemical indices.Compared with the control, the relative weight of spleen and kidney were significantly increased(P < 0.05) in the Fe-Gly groups.The iron contents in liver,spleen, kidney and femur were also found increased(P < 0.05) in the Fe-Gly groups.The RBC(d 1 and 21),HGB(d 1 and 21) and HCT(d 1 and 21) in blood and Fn(d 1) and SI(d 1 and 21) significantly increased(P < 0.05), but the TIBC(d 1 and 21) in serum decreased(P < 0.05) in the Fe-Gly groups.Moreover, the kidney relative weight, iron content in liver, spleen, kidney and femur, RBC(d 1) and HGB(d 21) in blood, and SI(d 1)in the Fe-Gly groups increased(P < 0.05) compared with the FeSO_4·H_2O treatment.Linear and quadratic responses of the kidney relative weight, the iron content in liver, spleen, kidney and femur, RBC(d 1 and 21),HGB(d 1 and 21) and HCT(d 1 and 21) in whole blood, SI(d 1) and TIBC(d 1 and 21) in the Fe-Gly groups were observed(P < 0.05).Linear responses of Fn(d 1 and 21) and SI(d 21) in the Fe-Gly groups, and spleen relative weight, HCT(d 1), Fn(d 1) and TIBC(d 1 and 21) in the FeSO_4·H_2O groups were observed(P < 0.05).These finding suggest that Fe-Gly supplemented at the level of 110 mg/kg in the diet of sows in this experiment is superior to other forms of supplementation, based on HGB concentration, the relative organ weight, tissue iron contents and blood biochemical indices of piglets.
