Objective To determine the appropriate dosage of parexoxib sodium for postoperative analgesia in different age children with day surgery.Methods One hundred and eighty ASA Ⅰ children aged 1-12 yr scheduled for day surgery undergoing sevoflurane anesthesia combined with lateral inguinal regional blockade were divided into 3 groups according to age ( n =60 each):group 1-3 yr (group Ⅰ ),group 4-6 yr (group Ⅱ ) and group 7-12 yr (group Ⅲ).Eeach group was randomly divided into 2 sub-groups( n =30): parecoxib sodium 0.5 mg/kg (sub-group A) and parecoxib sodium 1.0 mg/kg (sub-group B).Sub-groups A and B received iv injection of paracoxib sodium 0.5 or 1.0 mg/kg respectively immediately at skin incision.Analgesic effect was evaluated by FLACC score (group Ⅰ ),CHEOPS score (group Ⅱ ) and VAS scroe (group Ⅲ) at 6(T1 ),12(T2 )and 24 h (T3)after operation.The effective analgesia was defined as FLACC score≤3,CHEOPS score≤7 or VAS score≤ 3.Side effects were also observed.Results Compared with sub-group B,FLACC score was significantly increased at T1 in sub-group Ⅰ -A ( P ＜ 0.01 ).There was no significant difference in CHEOPS score or VAS score between sub-groups Ⅱ -A and Ⅱ -B,and between sub-groups Ⅲ-A and Ⅲ-B (P ＞ 0.05).The incidence of effective analgesia was 97％ in group Ⅰ (93％ in group sub-group Ⅰ -A,100％ in sub-group Ⅰ -B),100％ in group Ⅱ and 93％ in group Ⅲ (97％ in sub-group Ⅲ-A,90％ in sub-group Ⅲ-B).There was no significant difference in the incidence of side effect between sub-groups Ⅰ -A and Ⅰ -B,between sub-groups Ⅱ -A and Ⅱ -B,and between sub-groups Ⅲ-A and Ⅲ-B ( P ＞ 0.05).Conclusion Parecoxib sodium 1.0 or 0.5 mg/kg can be used in postoperative analgesia in children aged 1-3 yr or 4-12 yr with day surgery respectively.

AIM:To investigate the role of anti-miR-21 oligonucleotide ( AMO) in the anti-leukemic activity of decitabine (DCA) in vitro.METHODS:AMO and scramble oligonucleotide (SCR) were constructed and transfected into HL-60 cells.The miR-21 expression was analyzed by real-time PCR to identify the transfection efficiency .The cells were treated with DCA at gradient concentrations (0.5, 2.0 and 4.0 μmol/L) for 48 h.The mRNA expression of human period circadian protein 3 (hPer3) was detected by real-time PCR.The early apoptotic rates were determined by flow cy-tometry with Annexin V/PI staining.Mean fluorescence intensities ( MFI) of CD117 and CD11b were also measured by flow cytometry.RESULTS:The miR-21 relative expression level in AMO group was significantly lower than that in blank group and SCR group (P<0.01).IC50 of DCA in AMO group was significantly lower than that in blank group and SCR group (P<0.01).With the same concentration of DCA, the early apoptotic rate, the mRNA expression of hPer3 and the MFI of CD11b in AMO group were significantly higher than those in blank group and SCR group (P<0.01).The MFI of CD117 in AMO group were significantly lower than those in blank group and SCR group ( P<0.01 ) .CONCLUSION:Activation of hPer3 expression plays an important role in enhanced anti-leukemic activity of decitabine by AMO in vitro.

Objective To investigate clinical value of inflame factors in child patients with sepsis at different time points before the diagnosis time.Methods A retrospective model was performed in this study.24 child patients with sepsis in Department of Paediatrics from January 2014 to October 2016 were selected.At the time 72 h(group A),48 h(group B),24 h(group C) before the diagnosis time,plasma levels of HBP and serum levels of IL-6,IL-10 were detected by ELISA,and pre calcitonin (PCT) and high sensitive C reactive protein (hs-CRP) were detected by immunofluorescence.Compared to the same period,22 healthy cases were selected as the control.Repeated measure anova and Receiver operating characteristic curve analysis were performed.Results The plasma levels of HBP were (9.69 ± 1.30) μg/L,(12.82 ±2.03) μg/L,(15.46 ± 1.02) μg/L,(18.60 ± 1.10) μg/L at group A,group B,group C before the diagnosis time respectively.The plasma levels of HBP at all time points before the diagnosis time were significantly higher than the control (t =6.27,P ＜ 0.01;t =16.82,P ＜ 0.01;t =25.16,P ＜ 0.01).The serum levels of HBP at group B,group C were significantly higher than the last time point (t =5.62,P ＜0.01;t =10.25,P ＜ 0.01).Receiver operating characteristic curve(ROC) revealed that the areas of HBP at group A(0.823),group B (0.898),was significantly higher than the other inflame factors(Z =2.41,P ＜0.01;Z=2.02,P＜0.05;Z=0.38,P＞0.05;Z=0.32,P＞0.05)(Z=0.43,P＞0.05;Z=0.46,P＞0.05;Z =0.26,P ＞ 0.05;Z =0.57,P ＞ 0.05).It also revealed that at group C,area of PCT(0.941) was significantly higher than the other inflame factors (Z =0.12,P ＞ 0.05;Z =0.08,P ＞ 0.05;Z =0.03,P ＞0.05;Z-0.10,P ＞ 0.05).Conclusions HBP has a wide diagnostic window period for sepsis.IL-6,IL-10,PCT and hs-CRP have diagnostic value in partial periods of sepsis.

Objective To investigate iodine nutrition and thyroid health status among residents in Zhoushan archipelago, and to analyse their relationship.Methods A total of 3 284 residents in Zhoushan archipelago were surveyed by questionnaire and their thyroids were examined by B-mode ultrasound.The levels of urinary iodine and thyroid function were detected.Results The median level of urinary iodine in 3 284 residents was 226.0 μg/L, being 320.7 μg/L in citizens, 188.9 μg/L in farmers, 122.2 μg/L in salt-makers, 193.6 μg/L in fishers, and 271.7 μg/L in buddhist.The prevalence of diffuse goiter, nodular goiter, colloid goiter, thyroid adenoma, thyroid carcinoma, hyperthyroidism, subclinical hyperthyroidism, hypothyroidism, subclinical hypothyroidism, and positve rate of TPOAb were 1.7% ,25.3% ,8.7% ,0.2% ,0.4% ,0.5% ,0.8% ,0.03%,1.0% ,and 9.5% repectively.The prevalence of thyroid diseases was increasing with aging, and higher in women than in men (P＜0.05).There was no significant relationship of the thyroid diseases with seafood, smoking,drinking, and tea (P＞0.05).Conclusions The citizens of Zhoushan archipelago have adequate iodine intake.It is pertinent to discuss Universal Salt Iodization.Excessive iodine intake may contribute to the high prevalence rate of thyroid diseases in Zhoushan.

ObjectiveTo investigate the clinical characteristics,epidemiology of patients with severe fever with thrombocytopenia syndrome bunyavirus (SFTSV) infection and genetic sequences of SFTSV.MethodsClinical data of five cases of severe fever with thrombocytopenia syndrome (SFTS)from Zhoushan Hospital during May 2011 to July 2011 were retrospectively analyzed.SFTSV gene was amplified by polymerase chain reaction (PCR).CD3+ CD4+ and CD3+ CD8+T lymphocytes were detected by flow cytometry (FCM).The sequences of isolated SFTSV strains were compared with those in GenBank. ResultsThe symptoms of continuous high fever,sore muscles,enlarged superficial lymph nodes,abdominal pain,diarrhea with gastrointestinal hemorrhage were observed.The white blood cells,platelets and CD3+ CD4+ T lymphocytes were progressive decreased in acute phase with the minimum of (0.97-2.00) × 109/L,(12-42) × 109/L and 7.52％-20.39％,respectively.The SFTSV was isolated from the sera of two patients.The sequences were compared with SFTSV sequences in GenBank.The homology of RNA-dependent RNA polymerase gene was 96％ compared with BX-2010,L-WWG,LN3,JS4,SD4,HN6 and AH12; the glycoprotein gene was 94％ ; N protein gene was 95％ compared with JS4,SD4 and LN4.The homology of the above three genes between two isolates was 99％.ConclusionsOur results suggest that SFTSV is sporadic in Zhejiang Province which is probably from native epidemic focus.SFTS is progressive and severe with acute onset.Multiple organ dysfunction is common in severe eases.

Objective To investigate the risk factors of pregnancy-induced hypertension (PIH) in Zhoushan Area. Methods A total of 55 PIH patients who were treated in Zhoushan Women and Children Hospital from January 2010 to December 2012 were enrolled as the PIH group, and another 55 pregnant women without PIH were set as the control group. The serum calcium(Ca2+), phosphorus(P3+), total cesterol(TC), and triglyceride(TG) were detected by biochemical analyzer. Univariate and multivariate analyses were performed to reveal the potential correlations between these biochemical indicators and PIH. Results The serum levels of Ca2+, P3+, and TC between PIH group and control group were significantly different (P<0.01 or P<0.05), while the TG showed no significant difference between these two groups (P=0.15). Multivariate Logistic regression analysis showed that serum P3+and TC were risk factors for PIH (P<0.01 or P<0.05) whereas serum Ca2+was a protective factor (P<0.01). Conclusion Serum Ca2+, P3+and TC levels can be used for monitoring PIH in the islands.
