OBJECTIVETo investigate the incidence of accident proneness and its influencing factors in rural children.

METHODSBy random cluster sampling, 1 560 children were enrolled from one rural area in Hunan Province, China, and were surveyed with self-designed general and injury questionnaires. Unconditional multivariate logistic regression analysis was used to explore the major risk factors for accident-prone children.

RESULTSOne hundred and forty-seven accident-prone children were screened out and the incidence of accident proneness was 9.42%. Univariate analysis showed that gender (P<0.01), academic record (P<0.01), left-behind status (P<0.05), family type (P<0.05), family economic status (P<0.01), guardian's gender (P<0.05), guardian's marital status (P<0.05), guardian's occupation (P<0.05), and family educational mode (P<0.05) were influencing factors for accident proneness in rural children. Multivariate logistic regression analysis further revealed that low grade (OR=3.683, 95%CI: 1.028-4.283) and very low grade (OR=2.099, 95% CI: 1.587-8.546) in academic record, poverty in family economic status (OR=2.353, 95% CI: 1.222-4.533), and indulgence or indifference (OR=1.914, 95% CI: 1.029-3.559) and fickleness (OR=4.153, 95% CI: 1.847-9.338) in guardian's educational mode were risk factors for accident proneness in rural children, while female gender (OR=0.539, 95% CI: 0.369-0.788) was a protective factor.

CONCLUSIONSLow academic record, poor family economy, and incorrect family education mode (indulgence or indifference and fickleness) would increase the incidence of accident proneness in rural children, but girls have less accident proneness than boys.

Objective To explore the transtheoretical model(TTM) intervention effect on reducing communicative anxiety in obese children to improve their psychological status.Methods A quasi-experimental research was conducted in a randomly selected boarding school of Changsha.Seventy-three obese students with an average age of (9.60 ± 1.22) among Grade 3 to Grade 6 were included.After being enrolled in the intervention,all participants received the first assessment,including the stage-change scale and the communicative anxiety scale for children(including 2 parts:denial scary,social withdraw and annoyance).According to the baseline data,different intervention measures based on TTM were applied to different students.Follow-up assessments were collected respectively after 1-month and 6-month intervention,respectively.Repeated measurement data analysis of variance and follow-up Bonferroni test was conducted to assess intervention effect.Results Repeated measurement data ANOVA showed that after intervention,both scores of denial scary and social withdraw and annoyance significantly reduced(P ＜0.001),while body mass index had no significant difference (P ＞ 0.05).Follow-up Bonferroni test showed after 1 month intervention,social anxiety scores had no significant difference (P ＞ 0.05),while 6-month after the scores were significant different compared with pre-intervention and 1-month intervention(all P ＜0.05).Conclusions TTM intervention may effectively decrease communicative anxiety of obese children.Whether it can make BMI reduced significantly needs more research.

OBJECTIVE: To study the clinical effect of maternal voice stimulation in alleviating procedural pain in neonates during heel blood collection. METHODS: A total of 72 neonates who were admitted to the neonate intensive care unit were randomly divided into an intervention group (n=35) and a control group (n=37). Heel blood collection was performed by the routine method in the control group. The intervention group listened to their mothers' voice from 1 minute before heel blood collection to the end of the procedure. Pain score, incidence of crying, and vital signs were recorded before and after heel blood collection. RESULTS: Compared with the control group, the heart rate was significantly reduced, the blood oxygen saturation significantly increased, the incidence of crying and the pain score were significantly reduced in the intervention group during the procedure of heel blood collection (P<0.05). CONCLUSIONS Maternal voice stimulation helps to reduce procedural pain and maintain stable vital signs in neonates.

OBJECTIVETo analyze the codon usage of chloroplast genome and the influencing factor in Eleutherococcus senticosus.

METHODCodon of 52 genes, which were selected from the chloroplast genome sequence of E. senticosus, was multivariate statistical and correspondence analyzed using CodonW and SPSS software.

RESULTGC content at the three position of codons by turns was 46.46%, 38.26%, 29.88%, whereas GC1 and GC2 had a significant correlation coefficient (P < 0.01). The correlation coefficient with GC12, and GC3 was 0.205 and was not significant correlated. There were 30 codons which relative synonymous codon usage was greater than 1 and 29 codons end with A and T. In the corresponding analysis, the first axis shows 10.35% variation. And there was significant correlation coefficient between ENC and GC3. The correlation coefficients with GC3 and ENC were -0.288 and 0.353, respectively. We defined 16 codons from 16 amino acids as the major preference codons in chloroplast genome of E. senticosus.

CONCLUSIONThe third positions for all codon are preferred to ending with A and T. The codon usage bias is formed under effect of mutation and selection, as well as other factors. But the selection will have a far greater impact than others.

AIMTo observe effect of acute normovolemic hemodilution(ANH) with HAES-balanced solution as diluting agent on levels of cytokines including IL-1, IL-2, IL-6 and TNF-alpha in rabbit serum so as to provide theoretical basis for clinical application.

METHODSA total of 20 healthy adult rabbits were enrolled in the study and randomly divided into two groups (10 rabbits per group), i.e., control group (Group C) and HAES group (Group H). Under anesthesia of the rabbits, we performed incision of trachea, high-frequency jet ventilation and liberation of femoral artery and femoral veins. Group C was free from hemodilution. Group H was injected with dilution (2-fold of blood letting volume) via femoral veins during blood letting of the femoral artery. 6% HAES-steril plus compound solution of sodium lactate, with crystal/gel ratio of 2:1, blood letting volume = TBV x (Ho-Hf)/Hav. All blood was transfused back 60-120 min after blood letting. Venous blood was collected before blood letting (T0) and 30 min (T1), 60 min (T2), 120 min (T3) and 24 h(T4) after blood letting to detect Hb and Hct and measure level of IL-1, IL-2, IL-6 and TNF-alpha in serum.

RESULTSIn Group H, levels of IL-1, IL-2, IL-6 and TNF-alpha in serum were increased from T1 after ANH, reached peak at T3 but showed decrease at T4, with significant difference compared with Group C at T1, T2, T3 and T4 (P < 0.01) and significant difference compared with those before ANH (P <0.01). In Group C, there was no significant difference upon IL-1, IL-2, IL-6 and TNF-alpha in serum at different time points.

CONCLUSIONANH with HAES-balanced solution as diluting agent can up-regulate the levels of cytokines IL-1, IL-2, IL-6 and TNF-alpha in rabbit serum. In the meantime, ANH may arouse eustress with low intensity and short action time, which exerts effect of enhancing immune function of the organisms.

OBJECTIVE: To investigate the effect of placement of peripherally inserted central catheter (PICC) via the upper versus lower extremity veins in neonates through a Meta analysis. METHODS: CNKI, Wanfang Data, VIP Data, CBMdisc, PubMed, Web of Knowledge, Embase, Medline, Cochrane Library and Google Scholar were searched for control studies on the effect of PICC placement via the upper versus lower extremity veins in neonates. RevMan 5.3 was used to perform a Meta analysis of the studies which met the inclusion criteria. RESULTS: A total of 18 studies were included, among which there were 8 randomized controlled trials and 10 cohort studies, with 4 890 subjects in total. Compared with those undergoing PICC placement via the upper extremity veins, the neonates undergoing PICC placement via the lower extremity veins had significantly lower incidence rates of complications (RR=0.83, 95%CI: 0.75-0.92, P<0.05), catheter-related infections (RR=0.77, 95%CI: 0.60-0.99, P<0.05), catheter malposition (RR=0.28, 95%CI: 0.18-0.42, P<0.05), extravasation of the infusate (RR=0.52, 95%CI: 0.40-0.70, P<0.05), and unplanned extubation (RR=0.82, 95%CI: 0.69-0.98, P<0.05). They also had a significantly higher first-attempt success rate of puncture (RR=1.17, 95%CI: 1.05-1.30, P<0.05) and a significantly shorter PICC indwelling time (MD=-0.93, 95%CI: -1.26-0.60, P<0.05). CONCLUSIONS The above evidence shows that PICC placement via the lower extremity veins has a better effect than PICC placement via the upper extremity veins in neonates.

OBJECTIVE: To evaluate toxicity of raw extract of Panax notoginseng (rPN) and decocted extract of PN (dPN) by a toxicological assay using zebrafish larvae, and explore the mechanism by RNA sequencing assay. METHODS: Zebrafish larvae was used to evaluate acute toxicity of PN in two forms: rPN and dPN. Three doses (0.5, 1.5, and 5.0 µ g/mL) of dPN were used to treat zebrafishes for evaluating the developmental toxicity. Behavior abnormalities, body weight, body length and number of vertebral roots were used as specific phenotypic endpoints. RNA sequencing (RNA-seq) assay was applied to clarify the mechanism of acute toxicity, followed by real time PCR (qPCR) for verification. High performance liquid chromatography analysis was performed to determine the chemoprofile of this herb. RESULTS: The acute toxicity result showed that rPN exerted higher acute toxicity than dPN in inducing death of larval zebrafishes (P<0.01). After daily oral intake for 21 days, dPN at doses of 0.5, 1.5 and 5.0 µ g/mL decreased the body weight, body length, and vertebral number of larval zebrafishes, indicating developmental toxicity of dPN. No other adverse outcome was observed during the experimental period. RNA-seq data revealed 38 genes differentially expressed in dPN-treated zebrafishes, of which carboxypeptidase A1 (cpa1) and opioid growth factor receptor-like 2 (ogfrl2) were identified as functional genes in regulating body development of zebrafishes. qPCR data showed that dPN significantly down-regulated the mRNA expressions of cpa1 and ogfrl2 (both P<0.01), verifying cpa1 and ogfrl2 as target genes for dPN. CONCLUSION This report uncovers the developmental toxicity of dPN, suggesting potential risk of its clinical application in children.
