Objective To investigate the distribution of blood pressure and incidence of hypertension in children and adolescents from the urban area of Guiyang city aged 8-17 years old,in order to provide scientific evidence for preventing hypertension.Methods Seven thousand nine hundred and sixty-three primary and secondary students were sampled and standardized in blood pressure,height and weight.In accordance with the Working Group on Obesity in China(WGOC)recommendations,the subjects were divided into overweight,obesity and normal weight group,then the relationship between blood pressure and body mass index(BMI)and the prevalence of hypertension in different BMI groups were analyzed.Results 1.Compared with the USA and Shanghai city,the distribution of blood pressure in children and adolescents from the urban area of Guiyang city were different(Pa

Objective: To investigate the protective effect and mechanism of Pterocarya hupehensis Skan extract on liver injury induced by concanavalin A (conA). Methods:Forty C57BL/6 male mice were randomly divided into 5 groups: normal group, model group, and groups of low-, medium- and high-dose extract, with 8 mice in each group. Except for the normal group that received intravenous injection of normal saline, the other mice were injected with conA (12 mg/kg) for replication of the immunological liver injury model. The treatment groups were intragastrically administered with corresponding concentrations of extract. After 12 hours, the mice were subjected to eyeball extraction and dissection of liver tissue to prepare HE stained sections. The liver index was collected and calculated. Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were also detected. The content of STAT-3 and the level of phosphorylation in liver tissue were also tested. Results: HE staining showed that the liver tissue of the model group was significantly damaged compared with the normal group, and that of the treatment groups were ameliorated. Compared with the model group, each treatment group had reduced liver index and serum ALT, AST, IL-6 and TNF-α levels (P<0.05 or P<0.01). Significant phosphorylation of STAT-3 was observed in the model group, but it was inhibited in the treatment groups. Conclusion: The extract of Pterocarya hupehensis Skan can effectively treat immunological liver injury induced by conA, which may be related to the inhibition of phosphorylation of STAT-3.

Objective To compare the clinical outcomes of percutaneous cannulated lag screws versus posterior buttress plate in the fixation for posterior malleolar fractures.Methods We reviewed the 167 patients who had been treated between January 2010 and December 2014 for ankle fracture involving larger than 25％ of the articular surface of the posterior malleolus.They received posterior malleolus fixation with percutaneous cannulated lag screws or with a buttress plate.In the cannulated screw group (84 patients),there were 47 males and 37 females,aged from 23 to 72 years (average,49.7 ±9.1 years),and 39 cases of type B and 45 ones of type C according to the Dennis-Webber classification.In the buttress plate group (83 patients),there were 38 males and 45 females,aged from 31 to 69 years (average,52.3 ± 8.3 years),and 45 cases of type B and 38 ones of type C according to the Dennis-Webber classification.At 6 and 12 months postoperation and the final follow-up,the ankle motion was evaluated using American Orthopaedic Foot and Ankle Society (AOFAS) score and range of motion (ROM).Results The average operation time for the cannulated screw group was significantly shorter than for the buttress plate group (Z =-9.145,P ＜ 0.001).No fracture nonunion,reduction loss or incision infection happened in either group.In the cannulated screw group,we detected malunion with a step-off beyond 2 mm in 5 patients,and penetration of one cannulated lag screw into the tibiofibular syndesmosis in 3 patients.In the buttress plate group,we detected toe flexion contracture in 4 patients,and uncomfortable feeling in ankle motion in 7 patients.At the final follow-up,X-rays and CT scans in the 2 groups showed no obvious post-traumatic osteoarthritis of the ankle.There were no significant differences between the 2 groups regarding the AOFAS scores at 6 and 12 months postoperation and the final follow-up(P ＞ 0.05);the AOFAS scores at the final follow-up for all the patients were significantly different from those at 6 and 12 months postoperation (P ＜ 0.05).At the final follow-up,there were no significant differences between the 2 groups regarding ROMs of dorsal flexion,plantar flexion,varus or valgus (P ＞ 0.05).Conclusions As there are no significant differences between the percutaneous cannulated lag screws and posterior buttress plate in AOFAS score and ROM of the ankle after fixation for posterior malleolar fractures,the 2 fixation methods can both achieve good clinical outcomes.Fixation with cannulated lag screws has advantages of indirect reduction and minimal invasion but also a disadvantage of uncertain quality of reduction;fixation with buttress plates has an advantage of anatomical reduction under direct vision but also shortcomings of relatively large invasion and high cost.
