Network Pharmacology-Based Analysis on the Potential Biological Mechanisms of Yinzhihuang Oral Liquid in Treating Neonatal Hyperbilirubinemia. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:1672670. [PMID: 36248427 PMCID: PMC9556251 DOI: 10.1155/2022/1672670] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 07/18/2022] [Accepted: 08/08/2022] [Indexed: 11/10/2022]
Abstract
Objective Neonatal hyperbilirubinemia is caused by the excessive production of bilirubin and decreased excretion ability in the neonatal period. It leads to a concentration of blood bilirubin that exceeds a certain threshold. Yinzhihuang oral liquid (YZH) is a traditional Chinese medicine mixture used in the treatment of neonatal hyperbilirubinemia in China. This article systematically explores the pharmacological mechanisms by which YZH acts in the treatment of neonatal hyperbilirubinemia through network pharmacology at the molecular level. Methods We adopted the method of network pharmacology, which includes active component prescreening, target gene prediction, gene enrichment analysis, and network analysis. Results According to the network pharmacological analysis, 8 genes (STAT3, AKT1, MAPK14, JUN, TP53, MAPK3, ESR1, and RELA) may be targets of YZH in the treatment of neonatal hyperbilirubinemia. In addition, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses showed that YZH may regulate antioxidation, modulate lipid metabolism, and have anti-infective properties. Conclusion In this study, the pharmacological action and molecular mechanisms of YZH were predicted as a whole. It was found that YZH is a promising drug for treating oxidative stress due to bilirubin, as it reduces immunosuppression and helps to eliminate virus infection.

Abstract
Background Neonatal phototherapy (NNPT) has long been used as an effective and relatively safe method of treating neonatal hyperbilirubinemia. Considering the subsequent evidence of long-term impacts of NNPT such as malignancies, this study was conducted to evaluate the relationship between NNPT and childhood cancers. Methods This case-control study assessed 116 children up to 4 years old with every kind of cancer referred to the Oncology department of Afzalipour hospital, Kerman, Iran, from 2011 to 18. Moreover, 116 pediatric patients without cancer hospitalized at the same Center were included after sex and age matching as the control group. The history of phototherapy and its duration were evaluated in these two groups. Results We found no association between the NNPT and malignancies in children. However, high intensive phototherapy was higher historically among affected cancerous patients than in non-cancerous cases without any statistically significant difference (25% vs 19%; P = 0.26). Maternal educational level and history of maternal infection during pregnancy, which initially appeared to be two factors associated with malignancy in single variable regression analyses, were not significant based on the adjusted models. Conclusions The results did not show a positive correlation between NNPT and childhood cancers, which may partly be due to the relatively small sample size of the study. However, some other evidence is worrisome enough that NNPT should not be considered risk-free. Additional multi-centric studies should be undertaken to specify that phototherapy is really safe.

Abstract
BACKGROUND Phototherapy is the mainstay of treatment of neonatal hyperbilirubinaemia. Periodic change in position of the neonate under phototherapy (from supine to prone or lateral positions) may improve the efficiency of phototherapy by hastening the access of phototherapy light to bilirubin deposited in different parts of the skin and subcutaneous tissue. OBJECTIVES To evaluate the effects of periodic change of body position during phototherapy as compared to no prescribed change in body position, on serum total bilirubin level and duration of treatment in neonates with unconjugated hyperbilirubinaemia during the first 28 days of life. Secondary objectives of the review included evaluation of the efficacy of periodic change of body position on the need for or number of exchange transfusions, incidence of bilirubin-induced neurological damage (BIND), side effects of phototherapy, and sudden infant death syndrome (SIDS). SEARCH METHODS We used the standard search strategy of Cochrane Neonatal to run comprehensive searches in the Cochrane Central Register of Controlled Trials (CENTRAL; 2021, Issue 3) in the Cochrane Library and Ovid MEDLINE and Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Daily and Versions on 5 March 2021. We also searched clinical trials databases and the reference lists of included studies and relevant reviews for randomised controlled trials (RCTs) and quasi-RCTs. SELECTION CRITERIA We included RCTs and quasi-RCTs if they enrolled neonates (term and preterm) of either gender with unconjugated hyperbilirubinaemia requiring phototherapy and compared periodic change of the body position of the infant under phototherapy with no prescribed change in body position. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial quality and extracted data, consulting with a third review author in the case of disagreement. We used standard Cochrane methodological procedures, including assessing the risk of bias of included studies. We used the GRADE approach to assess the certainty of evidence. Primary outcomes were the duration of phototherapy and rate of fall of serum bilirubin at 24 hours. Secondary outcomes included the need for exchange transfusion, number of exchange transfusions, incidence of BIND, and SIDS. MAIN RESULTS We included five studies (343 neonates) with an overall high risk of bias in the review. The body position under phototherapy was changed every two hours or every two-and-a-half hours in two studies each, and every three hours in one study. Three of the five studies included healthy term neonates, whilst the other two studies also included preterm neonates (≥ 33 weeks' gestation); however, separate data about review outcomes in preterm neonates were not available. Periodic change in body position may lead to little or no difference in the duration of phototherapy (mean difference (MD) 1.71 hours, 95% confidence interval (CI) -3.17 to 6.59 hours; I² = 58%; 4 studies, 231 participants; low certainty evidence). Only one study reported the rate of fall of serum total bilirubin at 24 hours of starting the phototherapy. Periodic change in body position may lead to little or no difference in the rate of fall of serum total bilirubin at 24 hours (MD 0.02 mg/dL/h, 95% CI -0.02 to 0.06 mg/dL/h; 1 study, 100 participants; low certainty evidence). We downgraded the certainty of evidence to low due to risk of bias and imprecision. None of the included studies reported the need for or number of exchange transfusions, incidence of BIND, or SIDS. Lack of separate data precluded subgroup analysis. AUTHORS' CONCLUSIONS The available evidence is insufficient to determine the effects of periodic change of body position compared with no prescribed change of body position under phototherapy. There is low certainty evidence that there may be little or no difference in the duration of phototherapy and rate of fall in bilirubin at 24 hours of starting phototherapy between periodic change in body position and no prescribed change of body position under phototherapy in term and preterm neonates. None of the included studies reported the effect of change of position on the need for or number of exchange transfusions, incidence of BIND, or SIDS. One study is awaiting classification and could not be included in the review. Further studies are needed to evaluate the effect of periodic change in body position under phototherapy, especially in neonates with haemolytic hyperbilirubinaemia and in very preterm neonates. The results of this systematic review apply mainly to neonates born at late-preterm or term gestation receiving phototherapy for non-haemolytic hyperbilirubinaemia.

Abstract
Abstract
Background
Phototherapy is the main therapeutic interference for neonatal hyperbilirubinemia used to escape an exchange transfusion and to decrease the risk of bilirubin-induced encephalopathy (kernikterus). Phototherapy has an oxidative effect on cell components and cell membranes by enhancing peroxidation of lipid and damage to DNA. Many genes function as apoptosis regulatory genes. Examples of these genes involve the BCL2 gene as an anti-apoptotic oncogene, and the BAX gene which is a promoter of apoptosis.
We aimed to evaluate the effect of phototherapy on expression of BAX and Bcl2 genes in hyperbilirubinemic full-term neonates.
Eighteen full-term neonates with indirect hyperbilirubinemia who received phototherapy for 24 h were enrolled as a study group and nine apparently healthy full-term neonates with a normal serum bilirubin level were included as a control group. Assessment of the anti-apoptotic effect(s) of BCL2 and the pro-apoptotic effect(s) of (Bax) genes was achieved by quantitative assay of their products (BCL2 and BAX proteins) by ELISA assay after phototherapy.
Results
Significant decrease in the bcl2 (p < 0.001) and increase in Bax protein (p < 0.001) serum levels after phototherapy in hyperbilirubinemic full-term neonates.
Conclusion
Hyperbilirubinemia has no apoptotic influence, while phototherapy induces apoptosis in the peripheral blood of hyperbilirubinemic full-term infants.

Abstract
Background Neonatal jaundice affects at least 481,000 newborns every year. Phototherapy is recommended but it’s effects are limited and adverse reactions can occur. In China, phototherapy combined with Yinzhihuang oral liquid is also used for this condition. This systematic review evaluated the effectiveness and safety of combination therapy with Yinzhihuang oral liquid and phototherapy compared to phototherapy alone for treating neonatal jaundice. Method A comprehensive literature search was performed in four Chinese databases, two English language databases and two trial registries from inception to June 2017. Two authors independently screened the citations and retrieved full publications for randomized trials on Yinzhihuang oral liquid combined with phototherapy for neonatal jaundice. The methodological quality of the trials was assessed according to the Cochrane Collaboration’s tool for assessing risk of bias. Data were analyzed using RevMan 5.3. Result Totally 17 trials (involving 2561 neonates) were included in this review. Fourteen of them had a high risk of bias. Significant differences were detected between combination therapy and phototherapy alone for serum bilirubin level (MD − 50.25 μmol/L, 95% CI -64.01 to − 36.50, I2 = 98%; 7 trials, post-hoc decision choosing random effects model), failure of jaundice resolution (RR 0.21, 95% CI 0.14 to 0.32, I2 = 0%; 11 trials, fixed effects model), and time to jaundice resolution (MD − 2.17 days, 95%CI -2.96 to − 1.38, I2 = 98%; 6 trials, random effects model). Adverse events were reported in eight trials but none were serious. Trial sequential analysis for serum bilirubin level suggested that the cumulative Z-curve (which represents 1478 participants) reached the required information size (DARIS = 1301 participants). Conclusion Based on trials with low methodological quality, Yinzhihuang oral liquid combined with phototherapy seemed to be safe and superior to phototherapy alone for reducing serum bilirubin in neonatal jaundice. These potential benefits need to be confirmed in future trials using rigorous methodology. Trial registration Systematic review registration: [PROSPERO registration: CRD42016037691].

Abstract
Background: Hypocalcemia is one of the complications of phototherapy resulted from influence of phototherapy in melatonin secretion reducing corticosterone and ultimately increasing bone uptake. In this study, effect of head covering in prevention of this common and serious complication is studied. Materials and Methods: This prospective, randomized clinical trial study conducted on premature infants with gestational age <35 weeks with jaundice. Infants were divided into two groups (n = 43). The first group (intervention group) and the second group (control group) while on the cut, underwent phototherapy using four blue fluorescent lamps in distance of 35 cm. Eyes and genitalia were protected using appropriate clothing. In the first group, head was covered using cloth helmet with a suitable size. For both groups, serum calcium was measured before and 36 h after starting phototherapy. Results: Mean serum calcium before phototherapy in both intervention and control groups was 8.72 ± 1.12 and 8.79 ± 0.87 mg/dL, respectively, and the difference between groups was not significant (P = 0.76). After treatment, calcium level in both intervention and control groups was 8.9 ± 0.82 and 8.43 ± 0.91, respectively, and the difference between the two groups was significant (P = 0.015). Mean serum calcium levels after phototherapy in the intervention group was −0.17 ± 1.46 (increase) and it was 0.35 ± 0.71 (decrease) in the control group. According to t-test, the difference between the two groups was significant (P = 0.036). Conclusion: Head covering during phototherapy probably prevents from hypocalcemia.

Abstract
OBJECTIVE To determine the frequency of hypocalcemia in term neonates with jaundice receiving phototherapy. METHODS This was a cross sectional study conducted at Neonatal intensive care unit, National Institute of Child Health, Karachi from 1st January 2014 to 30th December 2014. A total of 123 term neonates with jaundice of either gender managed by phototherapy were enrolled in the study. Gestational age was assessed through modified Ballard scoring. Duration of phototherapy was recorded. A sample of 3 ml of blood was sent to the laboratory for serum calcium level before initiating phototherapy and after 24 hours of continued phototherapy. All the data were recorded in the preformed proforma. Data was analyzed using SPSS version 19. P value <0.05 was taken as significant. RESULTS The mean age of the neonates was 8.35±6.74 days. Mean gestational age at the time of birth was 39.08±1.37 weeks. Mean duration of jaundice was 2.4±1.20 days. Mean duration of phototherapy was 1.74±0.98 days. Serum calcium level before and after 24 hours of initiating phototherapy was 8.73±0.68 mg/dl and 7.47±0.82mg/dl respectively Frequency of hypocalcemia in term jaundiced neonates receiving phototherapy were observed in 22.76% (28/123). CONCLUSIONS The frequency of hypocalcemia is significant in the jaundiced neonates treated with phototherapy. One needs to be vigilant in dealing neonates in this context while serial monitoring for hypocalcemia and its complications should be considered in institutional policy and research priority.

Abstract
BACKGROUND It is well established that parents must interact with their new-born babies to facilitate attachment. However, very little is known about how parents perceive different types of medical technology products commonly used in the neonatal intensive care unit (NICU) as barriers to their wish to interact with their infants. AIM This study aims to examine to what extent the different medical technology products commonly used in the NICU are perceived by parents to be obstacles in their wish to interact with their babies. DESIGN AND METHODS In 2010, a cross-sectional survey, using a questionnaire specifically developed for this study, was conducted among the parents of children who were discharged from any of the five NICUs of the Västra Götaland region in Sweden. A consecutive sample of 248 parents participated, and multiple regressions and t-tests were used to analyse the data. RESULTS The parents generally perceived the various medical technology products differently, according to the perceived level of obstruction. The variables of gender, age, educational level, origin, gestational age, previous experience of being a parent, and the offer of accommodation at the NICU were significantly associated with the perceived level of obstruction in the parents' wish to interact with their baby while the baby was being treated with different medical technology products. CONCLUSION The primary implication for practice is that to facilitate attachment, nurses should involve different categories of parents in different ways in the care of their children, depending on the equipment being used in the treatment of the children. Thus, the individual care plan should explicitly include the details of the specific medical equipment, because although its use is medically beneficial for the child, it is associated with potential liabilities regarding parent-child interaction and, consequently, regarding parent-child attachment.

Abstract
INTRODUCTION This study was a two-center, stratified, parallel-group randomized trial comparing the effects of aggressive vs. conservative phototherapy on brainstem auditory evoked response (BAER) latencies in infants with extremely low birth weight (ELBW, ≤ 1,000 g). RESULTS BAER latencies of 751-1,000 g birth-weight infants were shorter by 0.37 ms (95% confidence interval (CI) = 0.02, 0.73) for wave V, 0.39 ms (0.08, 0.70) for wave III, and 0.33 ms (0.01, 0.65) for wave I after aggressive phototherapy at one center. Interwave intervals did not differ significantly. Similar nonsignificant trends were recorded for 501-750 g birth-weight infants. At the other participating center, no significant differences were recorded, cautioning against overgeneralizing these results. DISCUSSION The effects of bilirubin on the auditory pathway in ELBW infants depend on a complex interaction of bilirubin exposure, newborn characteristics, and clinical management. METHODS Aggressive phototherapy was initiated sooner and continued at lower bilirubin levels than conservative phototherapy. A total of 174 ELBW infants were enrolled in the study; 111 infants were successfully tested at 35 weeks postmenstrual age (PMA); 57 died; and 6 were not successfully tested.

Abstract
Phototherapy is the use of visible light for the treatment of hyperbilirubinemia in the newborn. This relatively common therapy lowers the serum bilirubin level by transforming bilirubin into water-soluble isomers that can be eliminated without conjugation in the liver. The dose of phototherapy is a key factor in how quickly it works; dose in turn is determined by the wavelength of the light, the intensity of the light (irradiance), the distance between the light and the baby, and the body surface area exposed to the light. Commercially available phototherapy systems include those that deliver light via fluorescent bulbs, halogen quartz lamps, light-emitting diodes, and fiberoptic mattresses. Proper nursing care enhances the effectiveness of phototherapy and minimizes complications. Caregiver responsibilities include ensuring effective irradiance delivery, maximizing skin exposure, providing eye protection and eye care, careful attention to thermoregulation, maintaining adequate hydration, promoting elimination, and supporting parent-infant interaction.

Abstract
Neonatal phototherapy (NNPT), a noninvasive, easily available therapy, has been widely used for the treatment of neonatal jaundice for more than half a century. Its efficiency in decreasing plasma bilirubin concentration is well documented, and NNPT leads to greatly reduced exchange transfusion rates for neonates with hyperbilirubinemia. It is generally accepted that the side effects of NNPT are not serious and seem to be well controlled. This review will focus on these possible side effects as well as the approaches to minimize them.

Abstract
AIM To describe the clinical approach to term and near-term newborn infants with severe hyperbilirubinaemia and to analyse the effect of high-intensity phototherapy on total serum bilirubin (TSB) levels. METHODS We analysed a cohort of 116 newborn infants with severe nonhaemolytic hyperbilirubinaemia (TSB ≥20 mg/dL/342 μmol/L). All patients were treated with high-intensity phototherapy. The main outcomes were reduction in TSB levels in the first 24 h of phototherapy, incidence of exchange transfusion, pathological brainstem auditory evoked responses and pathological findings on neurological examination at discharge. RESULTS The mean birth weight and gestational age were 3161±466 g and 37.8±1.6 weeks. Mean initial TSB concentration was 22.4±2.4 mg/dL. Per cent decreases in TSB after 2, 4, 6, 12, 18 and 24 h of phototherapy were 9.4%, 16%, 23%, 40%, 44% and 50%, respectively. No infant was treated with exchange transfusion. Brainstem evoked response audiometry (BAER) was performed in 100% of the patients, and in three of them, this examination was altered. However, when repeated 3 months later, these BAER examinations were normal. Neurological examination was normal in all patients. CONCLUSIONS High-intensity phototherapy significantly reduces TSB in nonhaemolytic severe hyperbilirubinaemia and decreases the need for exchange transfusion.
