Objective To evaluate the effect of the high concentration of sevoflurane wash-in in induction of anesthesia on the cardiac function in young infants.Methods ASA Ⅰ young infants,aged 28-60 days,undergoing resection of hemangioma on body surface under general anesthesia,were studied.According to the principle of randomized block design,8 blocks were designed based on the body weight (3.0-3.4 kg,3.5-3.9 g,4.0-4.4 kg,4.5-4.9 kg,5.0-5.4 kg,5.5-5.9 kg,6.0-6.4 kg,6.5-6.9 kg),with 3 infants in each block.The infants were randomly divided into 3 groups (n =8 each):anesthesia induction with 6％,7％ and 8％ sevoflurane groups (groups S1-3).In groups S1-3,the infants inhaled 6 ％,7 ％ and 8 ％ sevoflurane respectively for induction of anesthesia.Transthoracic echocardiographic examinations were performed before sevoflurane inhalation (baseline,T1) and at 4 min of sevoflurane inhalation (T2) to record the stroke volume (SV),left ventricle end-diastolic volume (LVEDV),ejection fraction (EF),stroke volume index (SI),heart rate (HR),cardiac output (CO),cardiac index (CI),peak early diastolic velocity of mitral annulus (Ea),peak late diastolic velocity of mitral annulus (Aa),peak systolic velocity of mitral annulus (Sa),and Tei index.The mitral annulus poteroseptal Ea/Aa (Ea/Aa) was calculated.Results Compared with the baseline value,SV,EF,SI,Ea/Aa and Tei index were significandy increased,HR,Sa,Ea and Aa were significantly decreased (P ＜ 0.05),and no significant change was found in LVEDV,CO and CI at 4 min of sevoflurane inhalation in groups S1-3 (P ＞ 0.05).Tei index was significantly higher in groups S2.3 than in group S1 (P ＜ 0.05).There was no significant difference in the parameters of cardiac function between group S2 and group S3 (P ＞ 0.05).Conclusion 6 ％,7 ％ and 8 ％ sevoflurane wash-in in induction of anesthesia exert no effect on the cardiac function in young infants,and the 3 concentrations can be recommended for clinical use.

Objective To detect the change of interleukin-18 (IL-18) level in the serum of patients with acute leukemia (AL) in children, and explore the clinical significance of IL-18. Methods The level of IL-18 was measured by sandwich enzyme-linked immuno-sorbent assay (ELISA) in 45 patients with AL in children. Results The leverof IL-18 in pre-treatment AL group was 719.35±358.21pg/mL and significantly higher than that of normal-control group [(311.80±146.64)pg/mL P <0.01]. Mter treatment, the level of IL-18 was 401.14±180.78 pg/mL in post-treatment complete remission group, which was significantly lower than that of pre-treatment group(P <0.01). The level of IL-18 in non-remission group was higher than those of normal control and CR group (P<0.01);while pre-treatment group the difference was not significant (P >0.05). According to the clinical sub-group with risk factors in pre-treatment AL, the level of IL-18 in high risk(HR) and middle risk(MR) group was significantly higher than low risk(LR) group (P<0.05). The level of IL-18 in T-ALL group was significantly higher than that in B-ALL group (P<0.05). The levels of IL-18 in pre-treatment AL were markedly correlated to the count of blast cells in bone marrow (r=0.411, P=0.005). Conclusion The level of IL-18 in the patients of childhood AL was in a high expression, and related to the clinical treating effect and the count of blast cells in bone marrow, which would be taken as an index of treating effect. The level of IL-18 was closely related to the clinical risk factors in pre-treatment AL.

Objective:To understand the genetic variation and the prevalence of H9N2 subtype avian influenza virus in Guizhou province, and to provide the scientific evidence for the prevention and control of avian influenza virus.Methods:The results of AIV detection in live poultry market(LPM) environment in Guizhou province from October 2018 to March 2019 were statistically analyzed, RNAs were extracted and sequenced from the HA genes of 13 samples of H9N2 positive screened by real-time PCR. Then the homology, the genetic evolution and the mutations of important amino acid were analyzed by bioinformation softwares. Results:The positive rate of AIV was 52.2% and the positive rate of H9N2 was 83.7% in LPM environment. The homology between nucleotides of the HA gene of 21 strains ranged from 91.6% to 100.0%, and the homology between amino acids of the HA gene ranged from 91.0% to 100.0%. All strains belonged to Y280 sublineage and G57 genotype. Key sites analysis showed that they had a common motif PSRSSRGLF and LSRSSRGLF at the cleavage site, which indicated that they were lentogenic and low pathogenic strains. Mutations H191N, E198T/A and Q234L at the receptor binding sites in the HA was found in 21 strains, while indicated the viruses had the potential to bind human-like receptor. The analysis results of glycosylation motifs showed that all 21 strains had 7 glycosylation sites, but had a site deletion at amino acid site 218 and an addition at 313.There was no significant mutation in the key site compared with the human infected strains. Conclusions:The detection rate of AIV in LPM environment in Guizhou province was high, and the pollution was very serious, and H9N2 subtype is the main subtype, All H9N2 subtype AIVs belonged to Y280 sublineage and G57 genotype, and they were low pathogenic avian influenza viruses in Guizhou province, but the genetic gap were widening and mutations of key amino acid site might enhance susceptibility and pathogenicity to human beings. Hence, It is necessary to strengthen the surveillance of molecular characteristic variation of H9N2 subtype AIV.

Objective To summarize the experience of multidisciplinary consultation for prenatal fetal deformity, and to explore the mode suitable for China. Methods The Obstetrics and Gynecology Hospital of Fudan University and Children's Hospital of Fudan University established a joint multidisciplinary consultation center, including obstetrics, pediatrics, pediatric surgery, ultrasound and other departments. A total of 3 378 pregnant women visited the consultation center from July 31, 2003 to August 1, 2013. After consultation, treatment was divided into three classes:pregnancy termination, pregnancy continuation and perinatal treatment. Follow-up was made through correspondence and telephone communication. Retrospective analysis on reasons for consultation, fetal structural abnormalities of the classification system, chronological order of abnormalities, gestational weeks of diagnosis, maternal-related factors, treatment and prognosis was performed. Results (1) Reasons for consultation:Among 3 378 women undertaking prenatal multidisciplinary consultation, 3 243 (96.00%) were due to fetal factors, and 135 (4.00%) were due to maternal factors. (2) Classification of fetal structural abnormalities:Among the 3 243 cases undertaking consultation with fetal factors, fetal abnormality was found in 80.85%(2 622/3 243). The most common were neurological abnormalities(23.19%, 608/2 622), followed by urinary tract malformation (20.25%, 531/2 622) and cardiovascular malformation (15.48%, 406/2 622). These were followed by digestive system malformation, limb deformities and space-occupying lesions. There were 156 cases of multiple malformations. (3) Average gestational weeks for diagnosis of fetal deformity:The 2 622 cases of fetal deformity were diagnosed at a mean (26.7± 2.1) of gestational weeks (21.1–30.4 weeks). Urinary tract malformations were detected at (24.0±0.7) weeks, whereas digestive system malformations were detected at (28.3±2.6) weeks. (4) Induced labor:Induced labor cases accounted for 35.66% (935/2 622), among which, 92 cases were fetal intrauterine death and 843 cases were active choice. The several highest induced labor rates resulted from multiple malformations (75.64%, 118/156), abdominal wall defects (62.22%, 28/45), diaphragmatic hernia (61.54%, 24/39), cleft lip and palate (55.32%, 26/47) and cardiovascular malformations (49.51%, 201/406). For nervous system (27.80%, 169/608), urinary tract (25.80%, 137/531) and digestive system malformations (26.94%, 66/245), induced labor rates were <30%. For abdominal lesions (14.04%, 25/178) and sacrococcygeal teratoma (13.64%, 3/22), induced labor rates were<15%. (5) Continuation of pregnancy in 1 687 cases:Cesarean section was conducted in 1 046(61.94%). Neonatal death occurred in 117(6.94%).(6) Perinatal treatment:Twenty-one cases were treated during pregnancy, including thirteen cases with fetal ascites and hydrothorax treated by drainage, five cases with fetal anemia treated by intrauterine transfusion and three cases with fetal tachycardia treated by digoxin. Ten cases were treated by ex-utero intrapartum treatment. After birth, 297 newborns immediately underwent neonatal surgery. Among these, 259 cases underwent radical surgery, eleven palliative surgery, and sixteen elective surgery after follow-up. Conclusions Prenatal multidisciplinary consultation can make comprehensive multidisciplinary assessment of fetal prognosis and improve the diagnosis and treatment of structural malformations.
