Objective To detect neuroendocrinal factor,and explore whether neurohormonal activation exists in children with conge-nital heart disease(CHD).Methods Concentrations of atrial natriuretic peptide(ANP),brain natriuretic peptide(BNP),angiotensionⅡ(AngⅡ),aldosterone(ALD),endothelin-1(ET-1),and norepinephrine(NE)were determined in 100 children with CHD and were assayed at 24 hours,1 month,3 months and 6 months after interventional therapy in 70 cases with CHD.Results Children with CHD heart disease had elevated levels of ANP(25.6?7.5) pmol/L,BNP(15.7?7.4) pmol/L,ET-1(1.12?0.31) pmol/L(all P=0.0001),(AngⅡ)(90.3?11.5) ng/L,NE(1.07?0.08) nmol/L and ALD(246.1?42.3) pmol/L(all P=0.001).There was a highly significant stepwise increase in ANP,BNP,ET-1,AngⅡ,ALD and NE according to New York Heart Association class,with even asymptomatic patients having evidence of significant neurohormonal activation.The neurohormonal function gradually returned to normal after interven-(tional) therapy.Conclusions Neurohormonal activation in children CHD bears the hallmarks of chronic heart failure,relating to symptom severity and ventricular dysfunction.

Objective To evaluate four tumor markers of insulin-like growth factor 1((IGF-1), CEA, cytokeratin fragment antigen 21-1 (CYFRA21-1), neuron-specific enolase (NSE) for the diagnosis and prediction of treatment response in human lung cancer. Methods Serum samples were taken from three groups: 91 patients with lung cancer, 30 healthy adults and 15 patients with benign pulmonary diseases. Serum IGF-1 was assayed by radioimmunoassay and CEA, CYFRA21-1, and NSE by electrochemiluminescence immunoassay. The differences among the three groups were determined by Kruskal-Wallis one-way analysis of variance (ANOVA) and with Mann-Whitney rank-sum test. Diagnostic efficacy was evaluated by ROC curves. Results The four serum tumor marker levels were significantly higher in lung cancer group, as compared with the benign and the healthy (IGF-1:χ2=26.95,P<0.001, CEA:χ2=49.11,P<0.001; CYFRA21-1:χ2=40.63,P<0.001; NSE:χ2=14.76;P<0.001). The diagnostic sensitivities of IGF-1, CEA, CYFRA21-1 and NSE was 75.6% (34/45), 53.3% (24/45), 66.7% (30/45) and 42.2% (19/45) respectively for lung cancer. The diagnostic sensitivity of IGF-1 combined with CYFRA21-1 was 95.5 %( 43/45) and that of IGF-1 combined with CEA and CYFRA21-1was 97.8%(44/45). Only IGF-1 and CYFRA21-1 showed significant changes before and after treatment (IGF-1: χ2=5.99,P=0.014; CYFRA21-1:χ2=4.99, P=0.025) in cancer group. Conclusions Serum IGF-1, CEA, CYFRA21-1 and NSE are all valuable for lung cancer diagnosis and the combination of those parameters can enhance the diagnostic efficiency. Serum IGF-1 and CYFRA21-1 may also be useful for evaluating the treatment response in lung cancer.

12 ml/s was used as Group A and Qmax ≤12 ml/s as Group B. Results One week after removal of urinary catheter, dysury appeared in five cases with Qmax for (9.45?2.62) ml/s, of which two cases were with posterior urethral stricture, two with benign prostatic hyperplasia and one with weak detrusor contraction. Three months after removal of urinary catheter, six cases led to secondary dysuresia due to posterior urethral stricture and had Qmax for (6.28?3.26) ml/s, with significant difference compared with urodynamic parameters of normal group (P

Clinical data and treatment of a patient with late-onset glutaric acidemia type Ⅱ who was admitted to the Department of Pediatric Intensive Care Unit (PICU) of Shenzhen Children′s Hospital were retrospectively analyzed.The patient is a female with the clinical manifestations of aggravated progressive proximal muscle weakness, accompanied by vomiting, abdominal pain and liver enlargement.A marked increase of transaminase, bilirubin and creatine kinase was detected, and hyperammonemia, hypoglycemia and metabolic acidosis were also observed in the patient.Blood amino acids and acylcarnitines spectra showed increased levels of various acylcarnitines.The muscle biopsy study suggested lipid storage myopathy (LSM), and the genetic test identified a homozygous mutation in the electron transfer flavoprotein dehydrogenase (ETFDH) gene.After treatment with Vitamin B 2, carnitine, coenzyme Q10 and plasma exchange, the motivate ability and biochemical parameters of the patient returned to normal.For patients with aggravated progressive proximal muscle weakness, hepatic dysfunction and increased serum creatine kinase levels, late-onset glutaric acidemia type Ⅱ should be considered.The key to early diagnosis and treatment of the disease is to improve the knowledge of it.

Objective To find a new indicator monitoring severe acute respiratory syndrome (SARS) by analyzing expression of lymphocytes and its subsets in SARS. Method Flow cytometer and hematology analyzer were used to detect the expression of lymphocytes and its subsets in 38 patients of SARS. Results Decreasing lymphocytes were found in 84 percent of the patients. The absolute value of lymphocyte subsets (T/B cell, NK cell) also decreased in a certain degree. Patients with decreasing T cell were mostly observed (95%). T helper/inducer (T 4)cells showed a higher rate of decreasing (100%) than T suppressor/killer (T 8)cells (87%). Based on the distribution of lymphocytes and its subsets, T cells demonstrated the greatest rate of decreasing (58%). Most patients had a relative normal B cells and NK cells with a rate of decreasing as little as 2.6% and 5.3%, respectively, more patients showed a decreasing T 4 cells (82%) than that of T 8 cells (34%). Forty-four percent of patients demonstrated a low ratio of T 4 to T 8. Conclusion The lymphocytes and its subsets were impaired in SARS, especially for T lymphocytes, T 4 cells were more seriously damaged than T 8 cells. The absolute counts of lymphocyte subsets showed more significant change of immune cells than relative counts of that in SARS.

Objective To evaluate the effects of long-term high-fat diet on skin wound repair in mice, and to explore its related mechanism. Methods A total of 16 ten-week-old C57BL/6J wild-type mice were randomly and equally divided into two groups to be fed a high-fat diet(HFD group)and a standard diet(SD group)respectively for 8 weeks. Then, an 8-mm full-thickness skin wound was created on the back of each mouse by using a biopsy punch. The degree of wound healing was observed, wound healing rate and epithelialization level were evaluated every day. The weight of mice was measured before feeding, after 8-week feeding and on day 14 after the operation. Peripheral blood samples were obtained from these mice for the determination of total cholesterol(TC)and triglyceride(TG)levels after a 12-hour fast on day 14 after the operation. Then, all the mice were sacrificed, and wound tissues were resected from the dorsal skin of mice for a histological study. The two-sample t test was used to compare the thickness of new epidermis in the wound surface, collagen deposition rate in the wound bed, count of new vessels, levels of cell proliferation and degree of inflammatory cell infiltration between the two groups. Results The average weight of mice was significantly higher in the HFD group than in the SD group after 8-week feeding(27.3 ± 0.7 g vs. 21.2 ± 0.6 g, t = 21.98, P < 0.001)and on day 14 after the operation (28.8 ± 0.7 g vs. 23.1 ± 1.1 g, t = 25.22, P < 0.001). Similarly, there was a significant increase in the levels of TC(1.35 ± 0.32 mmol/L vs. 0.99 ± 0.28 mmol/L, t = 2.24, P < 0.05)and TG(4.21 ± 0.41 mmol/L vs. 2.71 ± 0.31 mmol/L, t = 6.49, P < 0.05)in the HFD group compared with the SD group 14 days after the operation. Compared with the SD group, the HFD group showed shorter healing time (13.5 ± 0.5 days vs. 12.6 ± 1.1 days, t = 1.99, P < 0.05), lower thickness of newborn epidermis on the wound surface (47.8 ± 13.8 μm vs. 95.7 ± 13.7 μm, t = 5.68, P < 0.001), decreased number of CD31-positive vessels(8 ± 1 vs. 13 ± 3, t = 4.1, P < 0.001)and count of ki-67-positive cells(21 ± 4 vs. 49 ± 10, t = 3.33, P < 0.001), but increased count of infiltrating macrophages and mast cells (both P < 0.05). No significant difference was found in collagen deposition rate in the wound bed between the two groups (P > 0.05). Conclusion Long-term high-fat diet can affect wound healing and delay skin wound repair in mice.
