Objective To investigate the effects of enteral nutrition with galactooligosaccharides (GOS) on serum inflammatory cytokines in rats with severe acute pancreatitis (SAP). Methods SD rats were randomly divided into sham operation control group, SAP with enteral nutrition (EN) group and SAP with EN supplemented with GOS (GOS-EN) group, and each group was divided into 4 d and 7 d subgroups according to the time that animals were sacrificed (n=8 in each subgroup). Rat SAP models were established by injection of 38 g/L sodium taurocholate beneath the pancreatic capsule. The serum amylase, inflammatory cytokines TNF-α, IL-2 and IL-10 were detected. Results At each time point, the levels of serum amylase in all SAP groups were significantly higher than those in sham operation control group (P < 0.01), and the levels in GOS-EN group were significantly lower than those in EN group (P < 0.01). The levels of serum TNF-α and IL-10 in all SAP groups were significantly higher than those in sham operation control group (P < 0.01), while the levels of IL-2 in all SAP groups were significantly lower than those in sham operation control group. The levels of TNF-α in GOS-EN group were significantly lower than those in EN group (P <0.05), while the levels of IL-2 and IL-10 and the ratio of IL-10/TNF-α were significantly higher than those in GOS-EN group (P < 0.05). Conclusion Early EN supplemented with GOS could modulate the balance of pro- and anti-inflammatory response.

Objective To investigate the changes and potential roles of the expression of apoptosis signal-regulating kinase 1(ASK1),thioredoxin(Trx)and thioredoxin reductase(TrxR)in the pathogenesis of lung injury of premature newborn rats exposed to hyperoxia. Methods In the first day after delivery,preterm SD rats were randomly divided into air group and hyperoxia group with 64 rats in each.The rats were respectively sacrificed at 1,4,7,10 and 14 days after air or hyperoxia exposure.Sections of 1ungs were stained with HE to observe the histologic changes.Trx and TrxR mRNA were detected by reverse transcription-polymerase chain reaction(RT-PCR).Immunohistochemistry was used to detect the expression and distribution of ASK1.Western blot was used to detect the expression of ASK1 protein. Results Rats in hyperoxia group showed typical lung injury,which was characterized by alveolitis and delayed of lung development.Immunohistochemistry detected that ASK1 expressed generally in the cytoplasm of both alveolar epithelial cells and vascular endothelial cells:ASK1 protein expression in hyperoxia group at 1th and 4th day were 0.4382±0.0227 and 0.5270±0.0432,higher than in the air group(0.3458±0.0263 and 0.3760±0.0058)(P<0.01),and it was until 7th day that the expression became weaker(0.4343±0.0254),but still higher compared with the air group(0.3473±0.0220)(P<0.01).Compared with the air group,Trx and TrxR mRNA of the hyperoxia group increased significantly and peaked at lOth day(0.6860±0.0811)and 7th day(2.0351±0.1600),respectively(P<0.05).ASK1 protein expressions resulting

Objective To explore the effects of expression of thioredoxin-2(Trx-2) suppressed by small interference RNA(SiRNA) in A549 cells exposed to hyperoxia on expression of nicotinamide adenine dinucleotide(NADH) dehydrogenase subunit 1(ND1)and cytochrome C oxidase Ⅰ(COX Ⅰ). Methods A549 cells were gained by serial subcultivation in vitro and transfered with synthetic Trx-2 sequence-specific SiRNA and then were randomly divided into air group without interference,hyperoxia group without interference,air group after interference,and hyperoxia group after interference.After exposure to oxygen or room air for 12,24 and 48 h,expressions of Trx-2,ND1 and COX Ⅰ mRNA of these cells were detected by reverse transcription-polymerase chain reaction (RT-PCR),and Trx-2 protein was detected by Western blot. Results (1)Sequence-specific SiRNAtargeting Trx-2 could significantly down-regulate its expression in A549 cells.(2)Trx-2 mRNA levds inhyperoxia group without interference at 24 h was higher than those in air group without interference(0.7799±0.1249 VS 0.4424±Ⅰ.1140,P<0.05).Th-2 mRNA levels in hyperoxia group after ireedcrence at 24 hand 48 h were 0.2774±0.0174 and 0.2587±0.0069,lower than those in air group after interference andhyperoxia group without interference (P<0.05).(3)ND1 mRNA levels in hyperoxia group without interference at 24 h was 0.6609±0.0368,lower than those in air group without interference(0.8898±0.1049)(P<0.05).ND1 mRNA levels in hyperoxia group after interference at 12 h was 0.8848±0.0135,higher than those in air group after imederence(P<0.05).ND1 mRNA levels in hypemxia group afterinterference at 48 h was 0.3808±0.0937,lower than those in air group after imerference and hyperoxiagroup without interference(P<0.05).(4)COXI mRNA levels in hypemxia group without inteference at 12,24 and 48 h were 1.7313±0.4331,2.1929±0.6722 and 2.0754±0.2584,higher than those in air group witheUt interference,respectively (P<0.05). Conclusions ND1 and COXⅠ participate in thedevelopment of hyperoxia indUCed lung.injury,and Trx-2 is likely to have protective effect on mitochondria ofA549 cells in hyperoxia lung injury.

Objective:To systematically review parents ′ experience of caring for children with chronic kidney disease (CKD) to fully understand care needs and improve the psychological state and caregiving quality of parents. Methods:The qualitative studies on parents ′ experience of caring for children with CKD were retrieved from following databases, including PubMed, Web of Science, CNKI, VIP, CBM, and WanFang Data from inception to March 2020. The quality of included researches was evaluated according to the JBI Critical Appraisal Tool for qualitative studies in Australia. The results were integrated by pooled integration methods. Results:A total of 14 studies were included. 69 results were summarized and integrated to form 10 categories. These categories extracted 4 integrated results: parents' physical and mental condition are affected, relationship between parents and their support system has changed, reconstruction of parents ′ life, unmet care needs and problems. Conclusions:Parents are crucial to the disease management of children with CKD, so clinical medical staff should not only provide medical services for children, but also pay more attention to the psychological status and needs of parents, so as to provide guidance and support to promote parents to better implement care and disease management for children.

Objective To investigate the effects of rehabilitation stroke unit on patients with shoulder-hand syndrome after stroke. Methods 90 stroke patients with shoulder-hand syndrome were divided into two groups: control group (45 cases) was treated with conventional treatment and experimental group (45 cases) was incorporated into the rehabilitation stroke unit. The therapeutic course was 6 weeks.Brunnstrom stage, Fugl-Meyer assessment (FMA) and modified Barthel index (MBI) were used to assess the degree of the motor function of upper limb and hand, and activities of daily living (ADL), and the total clinical efficacy were evaluated. Results The motor function of upper limb and hand and ADL improved in both groups after treatment (P<0.05), while the experimental group was significantly superior to the control group (P<0.05). Conclusion Rehabilitation stroke unit has preferable effect on shoulder-hand syndrome after stroke.

Objective To investigate the effect of maternal age,gestational weeks,numbers of previous spontaneous abortion and embryo gender on chromosomal abnormalities.Methods Bacs on Beads (BoBs) technology was used to detect the chromosome aneuploidy of 245 pregnant women with spontaneous abortion or stillbirth in Jinan Maternity and Child Care Hospital from January 2015 to December 2017 and to analyze the types of their chromosome abnormalities.Comparative analysis between different groups was carried out using Chi-square test.Results Karyotypes of all cases (n=245) were obtained using BoBs.Among them,113 had chromosome abnormalities (46.1％),including 66 autosomal aneuploidy (58.4％),26 sex chromosome aneuploidy (23.0％),seven autosomal partial trisomy (6.2％),five autosomal partial monomer (4.4％),seven triploid (6.2％),one complex triploid (0.9％) and one double trisomy (0.9％).Pregnant women aged over 35 had a higher incidence of chromosome abnormality than those under 35 [61.0％ (36/59) vs 41.4％ (77/186),x2=8.003,P＜0.05].The incidence of chromosome abnormality of women aborted in the first-trimester was also higher than those aborted in the second-trimester [48.5％ (99/204) vs 34.2％ (14/41),x2=4.634,P＜0.05].Moreover,male embryos were more likely to have chromosome abnormality than female ones [57.6％ (49/85) vs 40.0％(64/160),x2=6.483,P＜0.05)].However,there was no significant difference between gravidas with different times of spontaneous abortion (0,1 or ≥ 2,P＞0.05).Conclusions Chromosome abnormality is a major cause of spontaneous abortion,particularly in embryos with chromosome aneuploidy,partial trisomy,partial monomer and triploid.Advanced maternal age may increase the risk of chromosome abnormalities in pregnancies complicated with spontaneous abortion or stillbirth.

Objective To evaluate the clinical diagnostic value of nucleic acid amplification (TB- RNA),bacteriophage-based assay,3D culture and smear on the detection of Mycobacteria tuberculosis.Methods 291 clinical sample including 110 sputum,54 thoracic fluid,37 throat swab,31 bronchial fluid,13 cerebrospinal fluid,12 urine,8 lymph fluid and 20 others (pericardial effusion,feces, blood and abdominal fluid) and gynecological specimen (including 6 leucorrhoea and menstrual blood) were analyzed by these four methods.Results Among the 291 clinical samples,the positive rate of mycobacteria tuberculosis for TB-RNA,bacteriophage-based assay,3D culture and smear were 37.1%,28.9%,27.5% and 10.3%.The sensitivity and specificity of the TB-RNA,bacteriophage-based assay,3D culture and smear were 54.3% & 100%,41.7% & 88.9%,31.7% & 93.5% and 14.6% & 98.9%,respectively.Conclusions TB-RNA is an effective clinical diagnostic method for Mycobacteria tuberculosis.Although the sensitivity of smear is poorer than others,it is a universal testing method in clinical laboratory due to low cost.The positive rate of mycobacteria tuberculosis for 3D culture is lower than that of bacteriophage-based assay and TB-RNA.Although the time to result for 3D culture might last for few weeks,the isolates can be used for drug resistance screening and bacterial identification.

OBJECTIVE: To evaluate the effect of health education on the symptoms, lung function and life quality in patients with stable chronic obstructive pulmonary diseases (COPD). METHODS: Eighty-two patients were assigned into 2 groups randomly: The treatment group (n = 43) accepted health education for 6 months and the control group (n = 39) did not. Before and after the 6 months, we observed the number of smokers, Borg score, inhale treatment, times of acute episode, SGRQ score, lung function, and the therapeutic effect in the two groups. RESULTS: Six months later, the ratio of smokers in the treatment group was 13.95%, much lower than that in the control group (35.90%, P = 0.021); the Borg score of the treatment group decreased from 4.86 +/- 1.21 to 3.38 +/- 0.94 (P =0.000), but there was no difference in the control group; the ratios of accepted inhale treatment in the treatment group and the control group were 100% (43/43) and 20.51 % (8/39) respectively (P = 0.000), and the accuracy rates were 100% (43/43 ) in the treatment group and 12. 82% (5/39) in the control group (P =0. 000); the times of acute episode in the treatment group was 1.51 +/- 1.53, much lower than that in the control group (4.46 +/- 5.17, P = 0. 000); the indexes of lung function before and after the 6 months between the two groups had no significant difference. The total score, the symptom section score, the activity section score, and the impact section score of SGRQ after the 6 months of health education were much lower than those of 6 months before, and those in the control group had no significant difference. CONCLUSION Six months of the health education can decrease the ratio of smokers and the times of acute episode, and to improve the life quality of patients with stable COPD.
