In vivo antiviral effect of plant essential oils against avian infectious bronchitis virus.

BACKGROUND: Infectious bronchitis virus (IBV) leads to huge economic losses in the poultry industry worldwide. The high levels of mutations of IBV render vaccines partially protective. Therefore, it is urgent to explore an effective antiviral drug or agent. The present study aimed to investigate the in vivo anti-IBV activity of a mixture of plant essential oils (PEO) of cinnamaldehyde (CA) and glycerol monolaurate (GML), designated as Jin-Jing-Zi. RESULTS: The antiviral effects were evaluated by clinical signs, viral loads, immune organ indices, antibody levels, and cytokine levels. The infection rates in the PEO-M (middle dose) and PEO-H (high dose) groups were significantly lower than those in the prevention, positive drug, and PEO-L (low dose) groups. The cure rates in the PEO-M and PEO-H groups were significantly higher than those in the prevention, positive drug, and PEO-L groups, and the PEO-M group had the highest cure rate of 92.31%. The symptom scores and IBV mRNA expression levels were significantly reduced in the PEO-M group. PEO significantly improved the immune organ indices and IBV-specific antibody titers of infected chickens. The anti-inflammatory factor levels of IL-4 and IFN-γ in the PEO-M group maintained high concentrations for a long time. The IL-6 levels in the PEO-M group were lower than those in prevention, positive drug, and PEO-L groups. CONCLUSION: The PEO had remarkable inhibition against IBV and the PEO acts by inhibiting virus multiplication and promoting immune function, suggesting that the PEO has great potential as a novel anti-IBV agent for inhibiting IBV infection.

miR-144-3p aggravated cartilage injury in rheumatoid arthritis by regulating BMP2/PI3K/Akt axis.

OBJECTIVES: Present study aimed to illustrate the role of miR-144-3p in rheumatoid arthritis (RA). METHODS: N1511 chondrocytes were stimulated by interleukin (IL)-1ß to mimic RA injury model in vitro. Rats were subjected to injection of type II collagen to establish an in vivo RA model, and the arthritis index score was calculated. Cell viability was determined by Cell Counting Kit-8. The expression of cartilage extracellular matrix proteins (collagen II and aggrecan) and matrix metalloproteinase protein were determined by quantitative real-time polymerase chain reaction and western blots. Cell apoptosis was measured by flow cytometry. Enzyme-linked immunosorbent assay was applied to test the secretion of pro-inflammatory cytokines (IL-1ß and tumour necrosis factor-α). Tissue injury and apoptosis were detected by haematoxylin-eosin staining and terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labelling assay staining. Interaction of miR-144-3p and bone morphogenetic protein 2 (BMP2) was verified by dual-luciferase assay. RESULTS: miR-144-3p was dramatically increased in IL-1ß-induced N1511 cells. miR-144-3p depletion elevated cell viability, suppressed apoptosis, pro-inflammatory cytokine releasing, and extracellular matrix loss in IL-1ß-induced N1511 cells. Moreover, miR-144-3p targeted BMP2 to modulate its expression negatively. Activation of phosphatidylinositol 3-kinase (PI3K)/Akt signalling compromised inhibition of BMP2 induced aggravated N1511 cell injury with IL-1ß stimulation. Inhibition of miR-144-3p alleviated cartilage injury and inflammatory in RA rats. CONCLUSION: Collectively, miR-144-3p could aggravate chondrocyte injury inflammatory response in RA via BMP2/PI3K/Akt axis.

Influence of Shared Decision Making on Decisional Conflict and Regret in Postpartum Mother-Infant Care: A Randomized Controlled Trial.

OBJECTIVES: Although postpartum rooming-in is encouraged by the World Health Organization, independent separated nursery care is still widely adopted in Eastern countries. Our aim is to evaluate the effect of shared decision making (SDM) assisted by patient decision aids on subjective decisional conflict and regret among women who are required to make choices regarding postpartum infant care. METHODS: A total of 196 pregnant women who came for routine checkups 1 month before delivery were randomly assigned to the SDM group or the classic group. Before the mothers were discharged after delivery, their decision-making difficulties were evaluated. The primary outcome was the decisional conflict, which was assessed using the SURE (Sure of myself; Understand information; Risk-benefit ratio; Encouragement) scale. The secondary outcome was the decisional regret, which was measured using the Decision Regret scale. RESULTS: Compared with the classic group, SDM group had surer feelings about the choice (P＜.001), felt more confident about knowing the benefits and risks of each option (P＜.001), had a clearer understanding of the benefits and risks (P＜.001), and felt sufficiently supported with enough advice to make a suitable choice (P＜.001). No significant difference was noted in the Decision Regret scores between groups. The choice of 24-hour rooming-in, 12-hour rooming-in, and separated nursery care was not significantly different between groups. CONCLUSIONS: SDM reduced the decisional conflict and uncertainty of the mothers. Available choices of postpartum mother-infant care should be provided to mothers through SDM that includes individual values, health goals, and clear knowledge and transparency.

[Reporting standards for expert consensus on clinical practice of Chinese patent medicines of China Association of Chinese Medicine].

In 2018,Standardization Department of China Association of Chinese Medicine invited methodologists with the background of evidence-based medicine to discuss and draft a series of standards for expert consensus on clinical practice of Chinese patent medicines. These standards have been made by reference to the published standards for developing expert consensus and clinical practice guidelines. These standards were made based on full consideration of the current evidence status and the history of clinical practice of Chinese patent medicines. These standards were composed of four parts,namely information summary items,normative general items,normative technical items and information supplementary items,including cover,content,preface,introduction,title,scope,basic Information of Chinese patent medicine,suggestions for clinical application,safety,conflict of interest,appendix,and references,so as to provides reference for improving the quality of expert consensus-based compilation and enhancing the applicability of expert consensus.

[Guidance of instructions for compiling expert consensus on clinical practice of Chinese patent medicine of China Association of Chinese Medicine].

The expert consensus on clinical practice of Chinese patent medicines shall be regarded as the same with clinical practice guidelines,which shall be concise,readable and applicable. Therefore,a formal expert consensus is unable to contain the whole compilation process and the content of its important process documents. It is necessary to write instructions for continuation,expansion and publicity. In 2018 Standardization Department of China Association of Chinese Medicine invited methodologists with the background of evidence-based medicine drafted a series of standards for expert consensus on clinical practice of Chinese patent medicines,including the guidance for compilation the instructions. It will be useful for readers of expert consensus to understand the work behind the compilation,so as to make the compilation process more transparent and standardized. We proposed nine requirements for compilation the instructions,namely content and requirements,work overview,main technical content,compilation process,process and basis for handling major disagreements,expert consensus implementation requirements and measure suggestions,other issues need to be explained,appendix and format for instructions.

[Manual for the clinical experts consensus of Chinese patent medicine].

Chinese patent medicine is widely used in clinical practice, but improper use will not only weaken the efficacy of drugs, but even cause adverse consequences. Evidence-based medicine provides guidance for clinical practice based on the best available evidence, experience of experts and needs of patients. However, considering the situation of "insufficient evidence" or "very low quality" in Chinese medicine research, experts consensus is the main basis for clinical decision-making, but expert opinions on which the consensus depends are susceptible to various subjective biases. Therefore, a reliable and scientific consensus-making process is needed to maximally avoid bias on consensus. Unlike the clinical practice guidelines, there is no unified formulating process for consensus in the world today. This article learns from a set of formulating processes from some international consensus formulating institutions/associations, combined with the characteristics and current situation of traditional Chinese medicine, and draws up a set of standard process that is suitable for the clinical experts consensus on Chinese patent medicine, with the expect of providing evidence and reference for consensus makers, and then bringing evidence-based assistance for the clinical standardized application of Chinese patent medicines.

Decrease in fertilization and cleavage rates, but not in clinical outcomes for infertile men with AZF microdeletion of the Y chromosome.

This study aimed to explore whether the presence of a Y chromosome azoospermia factor (AZF) microdeletion confers any adverse effect on embryonic development and clinical outcomes after intracytoplasmic sperm injection (ICSI) treatment. Fifty-seven patients with AZF microdeletion were included in the present study and 114 oligozoospermia and azoospermia patients without AZF microdeletion were recruited as controls. Both AZF and control groups were further divided into subgroups based upon the methods of semen collection: the AZF-testicular sperm extraction subgroup (AZF-TESE, n = 14), the AZF-ejaculation subgroup (AZF-EJA, n = 43), the control-TESE subgroup (n = 28) and the control-EJA subgroup (n = 86). Clinical data were analyzed in the two groups and four subgroups respectively. A retrospective case-control study was performed. A significantly lower fertilization rate (69.27 versus 75.70%, P = 0.000) and cleavage rate (89.55 versus 94.39%, P = 0.000) was found in AZF group compared with the control group. Furthermore, in AZF-TESE subgroup, the fertilization rate (67.54 versus 74.25%, P = 0.037) and cleavage rate (88.96 versus 94.79%, P = 0.022) were significantly lower than in the control-TESE subgroup; similarly, the fertilization rate (69.85 versus 75.85%, P = 0.004) and cleavage rate (89.36 versus 94.26%, P = 0.002) in AZF-EJA subgroup were significantly lower than in the control-EJA subgroup; however, the fertilization rate and cleavage rate in AZF-TESE (control-TESE) subgroup was similar to that in the AZF-EJA (control-EJA) subgroup. The other clinical outcomes were comparable between four subgroups (P > 0.05). Therefore, sperm from patients with AZF microdeletion, obtained either by ejaculation or TESE, may have lower fertilization and cleavage rates, but seem to have comparable clinical outcomes to those from patients without AZF microdeletion.

[Comparative proteomics study of different processing technology for pilose antler using iTRAQ technology coupled with 2D LC-MS].

This study was designed to use iTRAQ technology coupled with 2D LC-MS/MS to study the comparative proteomics of different processing technology for pilose antler. 1015 proteins were identified with 2D LC combined with MOLDI TOF/TOF mass spectrometry. Comparative analysis with Protein Pilot (Version 4.5) revealed that 87 proteins were changed (P ≤ 0.05, the ratio of > 1.50 or < 0.60 as the threshold selection of difference proteins), of which 24 were up regulated and 33 were down regulated in the traditional frying process (TFP) compared with the fresh pilose antler (P ≤ 0.05). 7 significant different proteins (P ≤ 0.001), most of these significantly changed proteins were found to be involved in calcium ion binding and ATP binding associated with human healthy. Freeze drying with protective agent (FDP) (Trehalose) can improve the content of significantly different proteins (P ≤ 0.001) including Collagen alpha-1 (XII) chain (COL12A1) and Collagen alpha-1 (II) chain (COL2A1). The significant function involves in platelets activating, maintenance of spermatogonium, and disorder expression in tumor cells. The functional annotation by Hierarchical clustering and GO (gene ontology) showed that the main molecule functions of the proteins significantly changed in these processes were involved in binding (52.7%), catalytic (25.3%), structural molecule and transporter (6.6%).

[Studies and reports of impact indicators on big brand Chinese medicine cultivation].

The policies and the access to market always attract the most attention for the enterprises, and whether the product is classified into the catalogue of health insurance or into the basic medicinal directory plays a pivotal role in the development of big brand. The uniqueness of the product can be regarded as a natural advantage, the construction of team of academic experts is more and more emphasized on the development of the product, and the security of the product deserves increasing attention.

Efficient and Selective Extraction of Rhamnogalacturonan-I-Enriched Pectic Polysaccharides from Tartary Buckwheat Leaves Using Deep-Eutectic-Solvent-Based Techniques.

Tartary buckwheat green leaves are considered to be among the most important by-products in the buckwheat industry. Although Tartary buckwheat green leaves are abundant in pectic polysaccharides, their potential applications in the food industry are quite scarce. Therefore, to promote their potential applications as functional or fortified food ingredients, both deep-eutectic-solvent-assisted extraction (DESE) and high-pressure-assisted deep eutectic solvent extraction (HPDEE) were used to efficiently and selectively extract pectic polysaccharides from Tartary buckwheat green leaves (TBP). The results revealed that both the DESE and HPDEE techniques not only improved the extraction efficiency of TBP but also regulated its structural properties and beneficial effects. The primary chemical structures of TBP extracted using different methods were stable overall, mainly consisting of homogalacturonan and rhamnogalacturonan-I (RG-I) pectic regions. However, both the DESE and HPDEE methods could selectively extract RG-I-enriched TBP, and the proportion of the RG-I pectic region in TBP obviously improved. Additionally, both the DESE and HPDEE methods could improve the antioxidant and anti-glycosylation effects of TBP by increasing its proportion of free uronic acids and content of bound polyphenolics and reducing its molecular weight. Moreover, both the DESE and HPDEE methods could partially intensify the immunostimulatory effect of TBP by increasing its proportion of the RG-I pectic region. These findings suggest that DES-based extraction techniques, especially the HPDEE method, can be promising techniques for the efficient and selective extraction of RG-I-enriched TBP.

Impacts of ultrasound-assisted Fenton degradation and alkaline de-esterification on structural properties and biological effects of pectic polysaccharides from Tartary buckwheat leaves.

Tartary buckwheat (Fagopyrum tataricum (L.) Gaertn) leaf has abundant rhamnogalacturonan-I enriched pectic polysaccharides, which exert various health-promoting effects. Nevertheless, the potential relationship between the chemical structure and the biological function of pectic polysaccharides from Tartary buckwheat leaves (TBP) remains unclear. Therefore, to bridge the gap between the chemical structure and the biological function of TBP, the impacts of ultrasound-assisted Fenton degradation (UFD) and mild alkaline de-esterification (MAD) on structural properties and biological effects of TBP were systematically studied. Compared with the native TBP (molecular mass, 9.537 × 104 Da), the molecular masses of degraded TBPs (TBP-MMW, 4.811 × 104 Da; TBP-LMW, 2.101 × 104 Da) were significantly reduced by the UFD modification, while their primary chemical structures were overall stable. Besides, compared with the native TBP (esterification degree, 22.73 %), the esterification degrees of de-esterified TBPs (TBP-MDE, 14.27 %; TBP-LDE, 6.59 %) were notably reduced by the MAD modification, while their primary chemical structures were also overall stable. Furthermore, the results revealed that both UFD and MAD modifications could significantly improve the antioxidant, antiglycation, and immunostimulatory effects of TBP. Indeed, TBP's biological effects were negatively correlated to its molecular mass and esterification degree, while positively linked to its free uronic acids. The findings demonstrate that both UFD and MAD modifications are promising techniques for the structural modification of TBP, which can remarkedly promote its biological effects. Besides, the present results are conducive to better understanding TBP's structure-bioactivity relationship.

Pectic polysaccharides from Tartary buckwheat sprouts: Effects of ultrasound-assisted Fenton treatment and mild alkali treatment on their physicochemical characteristics and biological functions.

Buckwheat sprouts are rich in pectic polysaccharides, which possess numerous health-improving benefits. However, the precise structure-activity relationship of pectic polysaccharides from Tartary buckwheat sprouts (TP) is still scant, which ultimately restricts their applications in the food industry. Hence, both ultrasound-assisted Fenton treatment (UAFT) and mild alkali treatment (MATT) were utilized for the modification of TP, and then the effects of physicochemical characteristics of original and modified TPs on their bioactivities were assessed. Our findings reveled that the UAFT treatment could precisely reduce TP's molecular weight, with the levels decreased from 8.191 × 104 Da to 0.957 × 104 Da. Meanwhile, the MATT treatment could precisely reduce TP's esterification degree, with the values decreased from 28.04 % to 4.72 %. Nevertheless, both UAFT and MATT treatments had limited effects on the backbone and branched chain of TP. Moreover, our findings unveiled that the UAFT treatment could notably promote TP's antioxidant, antiglycation, and immunostimulatory effects, while remarkedly reduce TP's anti-hyperlipidemic effect, which were probably owing to that the UAFT treatment obviously reduced TP's molecular weight. Additionally, the MATT treatment could also promote TP's immunostimulatory effect, which was probably attributed to that the MATT treatment significantly decreased TP's esterification degree. Interestingly, the MATT treatment could regulate TP's antioxidant and antiglycation effects, which was probably attributed to that the MATT treatment simultaneously reduced its esterification degree and bound phenolics. Our findings are conducive to understanding TP's structure-activity relationship, and can afford a scientific theoretical basis for the development of functional or healthy products based on TPs. Besides, the UAFT treatment can be a promising approach for the modification of TP to improve its biological functions.

[Impacts of Anthropogenic Emission Reduction on Urban Atmospheric Oxidizing Capacity During the COVID-19 Lockdown].

In recent years， regional compound air pollution events caused by fine particles （PM2.5） and ozone （O3） have occurred frequently in economically developed areas of China， in which atmospheric oxidizing capacity （AOC） has played an important role. In this study， the WRF-CMAQ model was used to study the impacts of anthropogenic emission reduction on AOC during the COVID-19 lockdown period. Three representative cities in eastern China （Shijiazhuang， Nanjing， and Guangzhou） were selected for an in-depth analysis to quantify the contribution of meteorology and emissions to the changes in AOC and oxidants and to discuss the impact of AOC changes on the formation of secondary pollutants. The results showed that， compared with that in the same period in 2019， the urban average AOC in Shijiazhuang， Nanjing， and Guangzhou in 2020 increased by 60%， 48.7%， and 12.6%， respectively. The concentrations of O3， hydroxyl radical （·OH）， and nitrogen trioxide （NO3·ï¼‰ increased by 1.6%-26.4%， 14.8%-73.3%， and 37.9%-180%， respectively. The AOC in the three cities increased by 0.06×10-4， 0.12×10-4， and 0.33×10-4 min-1， respectively， due to emission reduction. The meteorological change increased AOC in Shijiazhuang and Nanjing by 20% and 17.9%， respectively， but decreased AOC in Guangzhou by -9.3%. Enhanced AOC led to an increase in the nitrogen oxidation ratio （NOR） and VOCs oxidation ratio （VOR） and promoted the transformation of primary pollutants to secondary pollutants. This offset the effects of primary emission reduction and resulted in a nonlinear decline in secondary pollutants compared to emissions during the COVID-19 lockdown.

Potential structure-function relationships of pectic polysaccharides from quinoa microgreens: Impact of various esterification degrees.

Pectic polysaccharides are one of the most vital functional ingredients in quinoa microgreens, which exhibit numerous health-promoting benefits. Nevertheless, the detailed information about the structure-function relationships of pectic polysaccharides from quinoa microgreens (QMP) remains unknown, thereby largely restricting their applications as functional foods or fortified ingredients. Therefore, to unveil the possible structure-function relationships of QMP, the mild alkali de-esterification was utilized to modify QMP, and then the correlations of esterification degrees of native and modified QMPs to their biological functions were systematically investigated. The results showed that the modified QMPs with different esterification degrees were successfully prepared by the mild alkali treatment, and the primary chemical structure (e.g., compositional monosaccharides and glycosidic linkages) of the native QMP was overall stable after the de-esterified modification. Furthermore, the results revealed that the antioxidant capacity, antiglycation effect, prebiotic potential, and immunostimulatory activity of the native QMP were negatively correlated to its esterification degree. In addition, both native and modified QMPs exerted immunostimulatory effects through activating the TLR4/NF-κB signaling pathway. These results are conducive to unveiling the precise structure-function relationships of QMP, and can also promote its applications as functional foods or fortified ingredients.

Development of a colloidal gold immunochromatographic strip for rapid detection of avian coronavirus infectious bronchitis virus.

Avian infectious bronchitis virus (IBV) still causes serious economic losses in the poultry industry. Currently, there are multiple prevalent genotypes and serotypes of IBVs. It is imperative to develop a new diagnosis method that is fast, sensitive, specific, simple, and broad-spectrum. A monoclonal hybridoma cell, N2D5, against the IBV N protein was obtained after fusion of myeloma SP2/0 cells with spleen cells isolated from the immunized Balb/c mice. The N2D5 monoclonal antibody (mAb) and the previously prepared mouse polyclonal antibody against the IBV N protein were used to target IBV as a colloidal gold-mAb conjugate and a captured antibody, respectively, in order to develop an immunochromatographic strip. The optimal pH and minimum antibody concentration in the reaction system for colloidal gold-mAb N2D5 conjugation were pH 6.5 and 30 µg/mL, respectively. Common avian pathogens were tested to evaluate the specificity of the strip and no cross-reaction was observed. The sensitivity of the strip for detecting IBV was 10-1.4522 EID50/mL. The strip showed a broad-spectrum cross-reactive capacity for detecting IBV antigens, including multiple IBV genotypes in China and all of the seven serotypes of IBV that are currently prevalent in southern China. Additionally, the result can be observed within 2 min without any equipment. The throat and cloacal swab samples of chickens that were artificially infected with three IBV strains were tested using the developed strip and the qPCR method; the strip test demonstrated a high consistency in detecting IBV via qPCR gene detection. In conclusion, the immunochromatographic strip that was established is rapid, sensitive, specific, simple, practical, and broad-spectrum; additionally, it has the potential to serve as an on-site rapid detection method of IBV and can facilitate the surveillance and control of the disease, especially in resource-limited areas.

[Differences of Three Methods in Determining Ozone Sensitivity in Nanjing].

In recent years， ozone （O3） has become an increasingly important air pollutant in China. Identifying the sensitivity of O3 to the precursors volatile organic compounds （VOCs） and nitrogen oxides （NOx） can help make effective abatement strategies. This study compared three methods for determining O3-VOCs-NOx sensitivity： simulated photochemical indicator values and sensitivity coefficients derived from a three-dimensional air quality model and an observation-based model （OBM）， with a case study involving an O3 pollution event that occurred in Nanjing in late July 2017. The results showed that O3 sensitivity based on the photochemical indicator and sensitivity coefficients demonstrated similar spatial variations （over 50% of the grid cells of Nanjing exhibiting identical O3 sensitivity）. However， sensitivity coefficients identified a larger number of areas within a transitional O3 sensitivity regime， as opposed to the VOCs- or NOx-limited regime identified by the photochemical indicator. The determination of the latter was affected by the adopted threshold values. The OBM relied on the quality of the observational data. For example， positive biases in observed NO2 could lead to an underestimation of O3 sensitivity to NOx with the OBM. During the high pollution period， the three methods exhibited significant disparities. The photochemical indicator tended to suggest the VOCs-limited condition， whereas the OBM and sensitivity coefficients indicated the NOx-limited or transitional regimes.

Complete genome sequence of an infectious bronchitis virus chimera between cocirculating heterotypic strains.

To date, multiple serotypes and genotypes of infectious bronchitis virus (IBV) have been isolated and identified. In order to provide more information on the viral evolution of IBVs, a new virulent strain named GX-NN09032, isolated from Guangxi, China, in 2009, was sequenced, and phylogenetic and recombination analyses were conducted. Furthermore, potential recombination events associated with GX-NN09032 were found in four IBV strains, including GX-YL5, DY07, CK/CH/SD09/005, TC07-2. The present study suggested that GX-NN09032 might contribute to the emergence of modern IBV variants through recombination.

Continuous evolution of avian infectious bronchitis virus resulting in different variants co-circulating in Southern China.

Sixty field strains of avian infectious bronchitis virus (IBV) were isolated from chicken flocks in different regions of Guangxi from 1985 to 2012. Phylogenetic analysis of S1 subunit glycoprotein genes revealed that field isolates from 2009-2011 mostly belonged to the LX4 type, while those from 1985-2008 belonged to the HN08 type, and a few others belonged to the 4/91 type, the TW type and the Mass type. In addition, it is noteworthy that no obvious regional differences were found among these 60 strains isolated from six regions in Guangxi, while there was a high degree of sequence identity among the isolates in the same period of time.

The effectiveness of early intervention on paternal stress for fathers of premature infants admitted to a neonatal intensive care unit.

AIM: This article is a report of a study to evaluate the effectiveness of an intervention on fathering ability, perceived nurse's support and paternal stress after a preterm infant's admission to a neonatal intensive care unit. BACKGROUND: The birth of a premature infant who is admitted to a neonatal intensive care unit is a stressful experience. Due to the maternal postpartum practice in Taiwan, the father is the main visitor of the infant during the first few weeks, but interventions have rarely focused on the father. DESIGN: A historical comparison study. METHODS: Between August 2009-July 2010, 35 fathers in the comparison group received routine care; 34 fathers in the intervention group received a booklet designed for the fathers during their visits to the neonatal intensive care unit and nurses' guidance based on the contents of the booklet. Fathering ability, perceived nurse's support and paternal stress were measured. FINDINGS: The intervention group had a significantly higher fathering ability and perceived nurse support than the comparison group. In the intervention group, the increased fathering ability reduced paternal stress. After adjusting for severity of illness, an significant moderating effect of perceived nurse support on the relationship between fathering ability and paternal stress was found, accounting for 59·5% of variance. CONCLUSION: Designing a supportive intervention which provides informational, emotional, instrumental, and esteem support for the father can effectively empower his fathering ability and reduce his stress. The intervention should be initiated from the early admission of the premature infant to the neonatal intensive care unit.

[Neonatal asphyxia: a care experience using hypothermic therapy].

Hypothermia therapy, used to treat hypoxic-ischemic encephalopathy in neonates, has been shown to effectively decrease asphyxia complications and mortality. This article reports on an experience using this therapy approach to care for a neonatal asphyxic patient. Due to our lack of an appropriate cooling device, we adjusted the number of cool water bags to successfully perform hypothermic therapy. Despite this added procedural complication, we succeeded in saving the patient's life. The holistic care process for this type of case requires family-centered care to help family members deal with the critical condition and assist parents to face depression and guilt, reduce anxiety, and reaffirm the parent-child relationship. We used hypothermia in the initial stage. Relevant standards of critical care for this condition should be established to ensure adequate nursing care safety and quality.
