Objective　To observe the changes of glucocorticoi d receptor (GR) in hepatic cytoplasm in rats after scalding-induced pathologic al stress and its regulation. Methods　The receptor binding capa city (R0) and the apparent dissociation constant (Kd) of GR in hepatic cytopla sm of normal, low-degree and heavy-degree scalded rats were measured with rad io-ligand binding assay, with ［3H］ dexamethasone as ligand. The changes of R0 and Kd of GR were regulated by injections of anti-rat TNFα, IL-1β a ntibodies, α-melanocyte-stimulating hormone (α-MSH), and KPV peptide( Ac- D-Lys-L-Pro-D-Val) respectively in vivo. Results　The R 0 of GR in hepatic cytoplasm in rats 12 h after heavy-degree scalding ［Mass action robust: （205.52±30.14） fmol/mg; Scatchard: （208.45±30.78） fmol/mg ］were significantly lower than that of control group ［Mass action robust:（307 .86±24.22） fmol/mg;Scatchard:（306.71±27.96） fmol/mg］(P<0.01), but no s ignificant difference was found in the R0 of GR between the control and the ra ts 12 h after low-degree scalding ［Mass action robust: （285.19±16.62） fmol/ mg ; Scatchard: （296.64±16.06） fmol/mg］. The injection of anti-rat TNFα, IL-1β antibodies, α-MSH and KVP all prevented the decline of R0 of GR in h epatic cytoplasm in rats with severe scalding. Conclusion　The injections of anti-rat TNFα, IL-1β antibodies, α-MSH or KPV can attenuate the reduction of GR in rat hepatic cytoplasm caused by severe scalding-induced pathological stress to some extent.

OBJECTIVETo explore the influence of Astragalus membranaceus (AM) on serum cytokines, Th1, including interleukin-2 (IL-2) and gamma-interferon (gamma-IFN), and Th2, including interleukin-4 (IL-4) and interleukin-10 (IL-10), in patients with herpes simplex keratitis (HSK).

METHODSOne hundred and six HSK patients were randomly divided into the AM treated group and the ribavirin treated group. Levels of serum IL-2, IL-4, IL-10 and gamma-IFN of all the patients and 62 healthy person, selected from donors for control group, were determined by sandwich enzyme-linked immunosorbent assay (ELISA) technique.

RESULTSLevels of serum IL-4 and IL-10 in HSK patients were significantly higher and those of IL-2 and gamma-IFN were significantly lower than those in the healthy control (all P < 0.01). These parameters were significantly improved in the patients of the AM group after treatment, but with no change in patients of the ribavirin group.

CONCLUSIONAM can modulate the imbalance state of Th1/Th2 in HSK patients, improve their immune function disturbance, that shows important significance in treating HSK.

PURPOSE: This study aimed to evaluate the effects of cognitive-behavioral program on pain and medical fear in hospitalized school-aged children receiving intravenous (IV) placement. METHODS: This study used an quasi-experimental design. Thirty-five participants were assigned to the experimental group and 33 to the control group in the acute internal medicine ward of a children's hospital. The cognitive-behavioral program entailed having the patients read an educational photo book about IV placement before the procedure and having them watch their favorite music video during the procedure. The outcome measures were numeric rating scales for pain intensity and fear during the procedure. RESULTS: After applying the cognitive-behavioral program, the mean scores on pain and fear decreased in the experimental group. However, the difference in pain intensity between these two groups was nonsignificant. The intensity of fear in the experimental group was significantly lower than that in the control group. CONCLUSION: In this study, the cognitive-behavioral program used with school-aged hospitalized children promoted less fear during IV placement. The results of this study can serve as a reference for empirical nursing care and as care guidance for clinical IV injections involving children.

OBJECTIVETo evaluate the adrenocortical function in children with severe and critical enterovirus 71 infection by using a high-dose (250 µg) adrenocorticotropic hormone (ACTH) stimulation test. And to at provide experimental basis for glucocorticoid in the treatment of hand-foot-and-mouth disease (HFMD).

METHODThis was a prospective multi-center study which was carried out in PICUs of Beijing Children's Hospital, Zhengzhou Children's Hospital, Kaifeng Children's Hospital and Linyi People's Hospital in Shandong province. Children with severe and critical hand-foot-mouth disease admitted to PICUs of the four hospitals from June 2009 to April 2010 were enrolled in this study, and EV71 virus nucleic acid test and high-dose (250 µg) ACTH stimulation started at the same time. EV71 virus nucleic acid positive 51 cases were eventually enrolled in the study. Cortisol test was performed at baseline (T0) and after high-dose (250 µg) ACTH stimulation at 30 minutes (T30), 60 minutes (T60) in the first 6 hours after admission, but before glucocorticoid was given. The adrenocortical function was evaluated according to ΔTmax [ΔTmax=(T30, T60 maximum)-T0]. Diagnostic criteria of adrenal insufficiency (AI) is increment (ΔTmax)≤9 µg/dl.

RESULTThe incidence of AI in 51 cases was 52.94% (27/51). The incidence of AI in severe group was 44.74% (17/38), which was significantly higher in critical group 76.92% (10/13), P<0.05. Of the cases with a pediatric critical illness score (PCIS)≤70, 81.82% (9/11) had adrenal insufficiency, and it was 28.57% (4/14) when PCIS≥90. The incidence of AI was 75% (6/8) and 48.84% (21/43) in death and survivor group respectively, but there were no significant difference between the two groups (P>0.05). Baseline (T0) cortisol in death group was higher than survivor group (P<0.05).

CONCLUSIONAI may occur in children with enterovirus 71 infection. The critical enterovirus 71 infection had a high incidence of AI. AI may affect the prognosis of patients with severe and critical enterovirus 71 infection. Exogenous glucocorticoids administration may be considered when AI is identified or highly suspected. The timing, dosage and regimen of glucocorticoid are still unclear. Further animal experiments and clinical trials are needed.

Objective To summarize the experience of utilization of video-assisted endoscopy in 91 patients operated on at Chang Gung Memorial Hospital, Taipei, China.Methods From October 1995, through August 1996, 91 patients (44 male and 47 female) received video-assisted cardiac surgery (VACS). Their ages ranged from 1 year to 79.5 years (25.7±21.7). Indications for surgery were atrial septal defect (59 patients), ventricular septal defect (15), coronary artery disease (4), severe mitral regurgitation (4), severe tricuspid regurgitation (3), thrombosis of mitral mechanical prosthesis (3), left atrial tumor (2), and left ventricular thrombus with dilated cardiomyopathy (1). The VACS was performed through right or left anterior minithoracotomy and guided by video-assisted endoscopic techniques by means of projected images on the video monitor under extracorporeal circulation. The aorta was not cross-clamped and the myocardium was protected by continuous coronary perfusion with hypothermic fibrillatory arrest (rectal temperature 22.6±4.0℃). Conventional instruments were used.Results All lesions were corrected successfully. The bypass time was 27 to 335 minutes (72.8±52.7). The operative time was 1.3 to 8.5 hours (3.0±1.7). There were no operative deaths and 3 late deaths. Follow-up was complete in all survivors (6 to 16 months, mean 8.7). Most of them were found to be in NYHA functional Ⅰ or Ⅱ.Conclusion Our preliminary experiences demonstrate that VACS is simple and effective in surgical correction of selected cardiac lesions. Short-term results show good outcomes.

Objective:To investigate the feasibility of early treatment of congenital giant melanocytic nevus (CGMN).Methods:From October 2013 to December 2021, the clinical data of children with giant nevus treated with skin soft tissue expansion in the Plastic Surgery Department of Sun Yat-sen Memorial Hospital were analyzed retrospectively. A renal expander was implanted in the first stage, including single and repeated expansion. The giant nevus was removed and repaired in the second stage with an expanded skin flap. The occurrence of complications, such as wound infection, expander exposure, expander rupture, and flap congestion, were recorded. Children’s mental health problems and their parents’ satisfaction were also analyzed. The χ2 between children of different ages and the infection rate between children with an internal and external pot. Results:A total of 58 children, 24 males and 34 females, aged from 3 months to 3 years, with an average age of 1.45 years, were enrolled. A total of 190 expanders were implanted. The patients were followed for 5 to 106 months, averaging 42.43 months. In the first stage, 29 cases of wound infection, 41 cases of expander exposure, two cases of flap congestion, and 6 cases of expander rupture occurred. The flap transfers were not affected by these complications after appropriate treatment. The comparison of complication rates among 3 months~<1 year、1~<2 years、2~<3 years、3 years was 37.34%(31/83)、56.75% ((21/37) ), 33.33% (13/39) and 41.94%(13/31), respectively, No statistically significant difference ( χ2=5.21, P=0.157). The incidence of wound infection was 16.67% (6/36) and 14.94% (23/154), respectively, for the internal and external dilators. There was no significant difference in the location of the dilator pot and the incidence of wound infection ( χ2=0.07, P=0.795). The appearance of all children has been significantly improved. Thirty-nine children’s families are particularly satisfied, and 20 are generally satisfied with the treatment effect, and no mental health problems were found. Conclusions:Skin and soft tissue expansion is a reliable method for early treatment of congenital giant nevus.
