Objective To explore the relationship between maternal homocysteine (HCY), folic acid, 5, 10 methylenetetrahydrofolate reductase (MTHFR) genotypes(677C→T) and occurrence of congenital heart disease (CHD) in offspring. Methods HPLC technique was used to measure the level of total plasma HCY in 32 mothers of CHD children and 23 mothers of normal children, radio immunoassay was used to measure folic acid, and MTHFR genotypes were detected by PCR RELP analysis. Results The incidence of hyperhomocysteinemia(Hhe) (34%,11 cases) in CHD maternal group was significantly higher than that in normal maternal group( P

OBJECTIVE To analyze 28 cases in an outbreak of neonatal enterovirus nosocomial infection during summer of 2006.METHODS Demographic characteristics,clinical manifestations,laboratory data and outcome were analyzed to reveal the clinical severity.RESULTS The outbreak lasted more than one month and the nosocomial infection rate increased to 6.4%.There were 22 cases(78.6%) first presented with fever.Half of the patients were detected enterovirus from blood or cerebrospinal fluid by PCR.All of the 28 cases were diagnosed enterovirus infection based on the contact history,clinical signs and laboratory results.Among them,ten cases had viral meningitis.All patients discharged home after hospitalization with no sequelae.CONCLUSIONS Although this group of neonatal enterovirus infection developed viral meningitis,they had relatively mild illness with benign clinical course.Extreme vigilance is required in interrupting the spread of nosocomial enterovirus infections in neonatal units.This includes respect of strict hygiene measures and meticulous hand-washing.

OBJECTIVE: To evaluate the clinical effect of sublingual immunotherapy with dust mite for allergic rhinitis. METHOD: The symptom score of 188 patients with dust mite allergic rhinitis were recorded before and after treatment for six months, a year, and compare the treatment effects. RESULT: Symptom scores of 188 patients were decreased after treatment than before, the symptoms of treatment were improved significantly after six months, symptoms were improved more significantly after one year, the difference was significant (P<0.01). CONCLUSION Sublingual immunotherapy with dust mite is a safe and effective treatment for allergic rhinitis, and it is worthy of promotion.

Objective    To explore the safety and effectiveness of different interventional approaches for the treatment of patent ductus arteriosus (PDA) in children. Methods    The children (≤7 years) who underwent interventional treatment for PDA from 2019 to 2020 in our hospital were retrospectively included. The patients were divided into 3 groups according to the procedures: a conventional arteriovenous approach group, a simple venous approach group, and a retrograde femoral artery approach group. The clinical efficacy of the patients was compared. Results     A total of 220 patients were included. There were 78 males and 142 females, with an average age of 3.21±1.73 years, weight of 14.99±5.35 kg, and height of 96.19±15.77 cm. The average diameter of the PDA was 3.35±1.34 mm. A total of 85 patients received a conventional arteriovenous approach, 104 patients received a simple venous approach, and 31 patients received a retrograde femoral artery approach. The diameter of PDA in the retrograde femoral artery group was smaller than that in the other two groups (3.44±1.43 mm vs. 1.99±0.55 mm; 3.69±1.17 mm vs. 1.99±0.55 mm, P<0.001); the contrast medium usage [40 (30, 50) mL vs. 20 (20, 30) mL; 35 (25, 50) mL vs. 20 (20, 30) mL, P≤0.001] and operation time [32 (26, 44) min vs. 25 (23, 30) min; 29 (25, 38) min vs. 25 (23, 30) min, P<0.05] in the simple venous approach group were significantly less or shorter than those in the other two groups; the length of hospital stay of the conventional arteriovenous group was longer than that in the other two groups [3 (3, 5) d vs. 4 (3, 6) d; 4 (3, 5) d vs. 4 (3, 6) d, P<0.05]. There was no significant difference in postoperative complications. Conclusion    It is safe and effective to close PDA through simple venous approach. The retrograde femoral artery approach has the advantage of simplifying the surgical procedure for PDA with small diameters.
