Objective To discuss clinical results of the percutaneous minimally invasive LC DCP plating in treatment of tibiofibular fractures which was based on biological osteosynthesis and indirect reduction. Methods 28 patients with tibiofibular fractures were treated with indirect reduction and LC DCP plating through the tunnel inside tibia. Results All the patients were followed up for 10 to 18 months (averaging 15 m). X ray films showed that the callus appeared 4 to 7 weeks postoperatively (averaging 4.6 w). The fracture healing time were 12 to 18 weeks (averaging 12.8w). All the patients healed without fracture nonunion, delayed union or plate loosening. Plates were removed without refracture in 15 patients. Conclusions The percutaneous minimally invasive LC DCP plating for tibiofibular fractures can meet the major requirements of biological osteosynthesis and result in good results.

Objective To explore the developmental characteristics of different functional levels of autism and the diffe-rence in children. Methods A total of 159 autistic children aged 13-71 months including 85 high-functioning autistic (HFA) chil-dren and 74 low-functioning autistic (LFA) children were evaluated for their developmental characteristics by the development scales from the psycho-educational profile-revised (PEP-R). Results Within the same age group, both HFA and LFA children had obvious unbalance in individual ability development (H=41.68~113.51, P<0.01). Impaired cognitive performance is most common in HFA children. The development of cognitive performance was inconsistent with cognitive expression while the gross motor development was normal. The ability development in LFA children were all impaired, especially in imitation, cogni-tive performance and cognitive expression. With increasing age, the scores of imitation, perception, cognitive performance, cog-nitive expression and overall development quotient were increased gradually in HFA children (P<0.05) while the scores of cogni-tive performance and overall development quotient were decreased in LFA children. Conclusions Autistic children tend to have abnormal developmental progress and order, and individual ability development varies by functional level in autistic children with increasing age.

OBJECTIVEThis study aimed to explore the secular trends of overweight and obesity prevalence between 2007 and 2011 in children and adolescents in Guangzhou.
METHODSThe data of physical examination was collected from the routine measurements carried out by the Health Care Facilities of Primary and Secondary schools between 2007 and 2011. Random stratified cluster sampling was conducted, all the students aged 5-18 years old form 19 primary and secondary schools from 4 districts (Tianhe district, Yuexiu district, Baiyun district and Haizhu district) were included in this survey, including 27 944 students in 2007 and 38 284 students in 2011. Body mass index reference norm established by Working Group on Obesity in China (WGOC) and the WHO cut-off criteria were employed for overweight and obesity screening, and the trend was analyzed.
RESULTSPrevalence of obesity in children and adolescents (7-18 years old) significantly increased from 5.96% (1 553/26 055) in 2007 to 6.56% (2 339/35 664) in 2011, and the difference showed statistical significance (χ(2) = 9.195, P < 0.05). Overweight and obesity was more common in boys (overweight: 13.25% (1 766/13 329) in 2007 and 13.87% (2 559/18 451) in 2011; obesity: 7.82% (1 042/13 329) in 2007 and 8.63% (1 592/18 451) in 2011) than in girls (overweight: 7.43% (946/12 726) in 2007 and 8.17% (1 406/17 213) in 2011; obesity: 4.11% (523/12 726) in 2007 and 4.48% (771/17 213) in 2011), and the difference showed statistical significance (overweight:χ(2) = 236.123 in 2007 and χ(2) = 292.892 in 2011; obesity:χ(2) = 158.533 in 2007 and χ(2) = 247.794 in 2011. All P values < 0.05). Further analysis found that significant increases occurred in boys aged 16 and 17 years old and in girls aged 12 years old (boy: 16 years old,χ(2) = 6.820, P < 0.05. 17 years old, χ(2) = 4.893, P < 0.05. girl: 12 years old,χ(2) = 5.921, P < 0.05).
RESULTSof Join-point regression showed that for boys less than 10 years old the prevalence increased with age increasing (in 2007, APC = 3.75; in 2011, APC = 1.76), while over 10 years old the prevalence decreased with age increasing (in 2007, 10-18 years old's APC = -18.58; in 2011, 10-18 years old's APC = -15.95). While for girls the prevalence of obesity increased with age increasing between 7-9 years old (APC = 12.16), decreased with age increasing through 9 to 18 years old (APC = -17.23) in 2007. The prevalence decreased with age increasing for girls in 2011 (APC = -4.66).
CONCLUSIONThe prevalence of obesity is high and still increasing in children and adolescents in Guangzhou, and it is higher in boys than in girls. It is more likely to become obesity at 10 years for boys, and for girls the prevalence decrease with age increasing.

Objective To analyze the clinical value of immature granulocytes in peripheral blood for prediction of persistent systemic inflammatory response syndrome (SIRS) in patients with acute pancreatitis (AP). Methods 1 973 patients with AP in Hunan People's Hospital from 2012 to 2017 were retrospectively enrolled and divided by SIRS duration into the persistent SIRS group, temporary SIRS group and non-SIRS group. The independent risk factor for persistent SIRS in AP patients was evaluated by Logistic regression analysis, and predictive value of immature granulocytes for persistent SIRS in AP patients was analyzed by the receiver operating characteristic (ROC) curve. Results These 1 973 AP patients (1 165 males, 59.0%) with an average age of 49 (40, 60) years old, including 288 persistent SIRS, 189 temporary SIRS and 1 496 non-SIRS cases. There was no significant difference in gender, age and etiology among three groups. Compared with non-SIRS group, more severe symptoms were observed in the temporary and persistent SIRS groups. Moreover, The acute physiology and chronic health evaluation Ⅱ(APACHEⅡ), CT severity index (CTSI), multiple organ failure (MOF) and acute respiratory distress syndrome (ARDS) incidence, mortality and C-reactive protein (CRP), white blood cell count (WBC), procalcitonin (PCT) and immature granulocytes in persistent SIRS group were further higher than those in the temporary SIRS group [APACHEⅡ: 9 (6, 12) vs. 5 (3, 7), CTSI: 6 (4, 6) vs. 4 (3, 6), MOF incidence: 92.0% vs. 32.8%, ARDS incidence: 39.9% vs. 10.1%, morbidity: 11.1% vs. 4.2%, CRP (mg/L): 25.00 (0.80, 212.25) vs. 0.80 (0.80, 123.50), WBC (×109/L): 15.17±6.78 vs. 14.84±5.86, PCT (μg/L): 0.23 (0.10, 1.76) vs. 0.10 (0.10, 0.31), immature granulocytes: 1.95 (0.90, 4.95) % vs. 0.80 (0.40, 2.10) %, all P < 0.05]. Logistic regression analysis showed that besides pancreatic necrosis, WBC and CRP, immature granulocyte was an independent risk factor for persistent SIRS associated with AP [odds ratio (OR) = 1.844, 95% confidence interval (95%CI) = 1.372-2.220]. ROC curve showed that immature granulocytes had better predictive value for persistent SIRS, the area under the curve (AUC) was 0.806, which was significantly higher than the APACHEⅡ (AUC = 0.783), CTSI (AUC = 0.752), PCT (AUC = 0.676), CRP (AUC = 0.677), WBC (AUC = 0.644). The cut-off value of immature granulocyte was 0.65%, the sensitivity was 84.0%, the specificity was 66.3%, the positive predictive value was 62.4%, and the negative predictive value was 76.3%. Conclusion Immature granulocyte in peripheral blood is a potential indicator for persistent SIRS in AP patients.
