ObjectiveUsing large sample clinical study to reevaluate the safety and efficacy of recombinant human growth hormone(ANSOMONE) in treating pediatric growth hormone deficiency(GHD).Methods1012 cases were administered with ANSOMONE at a dose of 0.1 IU · kg-1 · d -1 in bedtime for 6 months.The alteration of mean height,growth rate,height standard deviation scores,bone age,and anti-GH antibody and occurrence of adverse effects were observed.ResultsThe growth rate was promoted from ( 2.50 ± 0.85 ) cm/year to ( 13.44 ± 4.27 ) cm/year,the net growth rate was( 10.94 ±3.69)cm/year.There was significant difference between the pre-treatment and post-treatment patients ( P ＜ 0.01 ).The post-treatment anti-GH antibody positive rate was 13.34％,which had no obvious effect on the efficacy.Few patients exert transient inflammation reactions,which disappeared with any treatment.ConclusionANSOMONE had significant efficacy,and could promote the height increase obviously.It had good safety without any obvious side effect and early-maturing effect.

Objective To evaluate the clinical application of the fistulography of multi-slice spiral CT(MSCT)in the diagnosis of anal fistula.Methods A total of 28 patients who were verified operatively of fistula in ano underwent preoperative fistulography of MSCT.The multi-planar reformation(MPR)and surface shadow display(SSD)images were generated and analyzed retrorespectively.Results There were 8 cases with perianal abscess and 20 cases with anal fistula in 28 patients.Complex fistula was diagnosed in 16 cases,and simple inter-sphincteric fistula was found in 4 cases;the inner orificiums of anal fistulas were revealed accurately with MPR images in 18 cases.Conclusion The fistulography of MSCT is valuable for preoperative assessment of anal fistula,in particular for investigation of the inner orificiums of anal fistulas with MPR.

This article describes the clinical case of a patient with renal insufficiency after receiving sensitizing drugs,which resulted in limb weakness and cognitive impairment of center nervous system characterized by vasculitis imaging and responded well to glucocorticoid treatment-DRESS syndrome.

BACKGROUND:Along with the widespread application of biodegradable materials in the field of medicine and the in-depth research of biomechanics,the drawbacks of traditional medical metal materials are increasingly appearing.In recent years,researchers at home and abroad focus on biodegradable materials that are represented by high molecular polymer to seek new breakthroughs in the field of spinal instability.OBJECTIVE:To investigate biomechanical changes of polylactic acid-polyglycolic acid (PLGA) lumbar interbody fusion cage in the body and discusses its feasibility for treating segmental instability of the spine.METHODS:Forty-two healthy pigs (9 months old) were randomly divided into two groups (n=21),and L4/5 intervertebral disc nucleus pulposus was removed in all animals.In experimental group,PLGA lumbar interbody fusion cage filled with broken bone was implanted;and in control group,autologous bone was implanted.X-ray was performed to observe the fusion of operation segments at 4,12 and 72 weeks postoperatively.Feasibility of fibrous fusion was measured by biomechanical test.Histologically,bone graft fusion at the surgical site and material degradation were detected.RESULTS AND CONCLUSION:(1) Imaging examination:Bone graft fusion in two groups was not visible at 4 weeks after operation.Evidence of increasing fusion was found in the experimental group at 12 weeks after operation;a visible part of the bone bridge was found in the control group,in which there was one case of fusion.Degradation of the fusion cage with one case of fusion in experimental group was found after 72 weeks after operation,and two cases of fusion in the control group.(2) Biomechanical test:There was no difference in the spinal range of motion between the two groups in different states at 4 weeks after operation (P ＞ 0.05).The spinal range values of motion at most of the states at 72 weeks after operation were significantly lower than those at 4 weeks after operation.(3) Cell histology observation:With the passage of time,the materials in the experimental group degraded gradually;new bone grew slowly and then fast,with bone fusion step by step.Fusion results were similar in the two groups.Our experimental findings indicate that the PLGA lumbar fusion cage has good biocompatibility.In addition to the individual state (left flexion),the mechanical properties of the fusion cage are similar to that of autogenous bone,and the fusion cage enables the segmental reconstruction of the pig spine to the maximum extent.

OBJECTIVETo examine the effect of particulate matter (PM) less than 10 microns in diameter (PM10) and ozone (O3) on daily mortality in Shanghai, China.

METHODSA generalized additive model with penalized spline function was used to observe the acute effect of PM10 and O3 on daily mortality.

RESULTSHigher PM10 significantly increased the effect of O3 on total mortality, and O3 also increased the effect of PM10 although the estimated increment was statistically insignificant.

CONCLUSIONOur findings provide further evidence for the effect of PM10 and O3 on daily mortality.

OBJECTIVETo explore the relationship between nitrite levels in the exhaled breath condensates (EBC) and the severity of asthma.

METHODSSixty asthmatic patients with exacerbation (including 23 with mild, 21 with moderate, and 16 with severe asthma) and 23 healthy nonsmokers were enrolled in this study. The lung function tests were performed and nitrite levels measured in the EBC by the spectrophotometry and nitric oxide assay kit in these subjects. The percentage of eosinophils was also measured in induced sputum by Wright staining.

RESULTSThe concentrations of nitrites in the EBC and the percentage of eosinophils in induced sputum in the asthmatic patients were significantly higher than those of the healthy subjects (P<0.01), and showed positive correlations to the disease severity. A significant positive correlation was found between nitrites in the EBC and percentage of eosinophils in induced sputum (r=0.706, P<0.01). The concentration of exhaled nitrites was inversely correlated to MEF50% (r=-0.806, P<0.01) and FEV1% (r=-0.724, P<0.01).

CONCLUSIONNitrite level in the EBC may serve as useful indicators for estimating the severity of asthma.

OBJECTIVETo study the effects of overweight and obesity on physical function (including systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse, weight vital capacity index) in children and adolescents.

METHODSThe data of 2010 Chinese National Survey on Students Constitution and Health was analyzed. The samples of overweight and normal-weight group were randomly selected from the data by matching gender, urban or rural for getting the same number sample size as obese group (10 601 each group). The students aged 7 - 18 years were classified into 3 groups by BMI percentiles (P₅, P₁₅, P₂₅, P₅₀, P₇₅, P₈₅ and P₉₅), to analyze the change of physical function along with BMI percentile.

RESULTSCompared to the normal-weigh group, SBP of the obese boys of all age groups increased by 8.0 - 12.0 mm Hg, DBP increased by 4.7 - 5.9 mm Hg, while SBP of the obese girls increased by 7.5 - 11.6 mm Hg, DBP increased by 4.7 - 6.1 mm Hg, with statistical significance (P < 0.05). In 13 - 15-year group, pulse of obese boys was 0.8 times/min higher than that of normal-weight. In 16 - 18-year group, pulse of obese boys was 1.1 times/min higher than that of overweight or normal-weight, while pulse of obese girls were 1.5 and 1.7 times/min higher than that of overweight and normal-weight, respectively (P < 0.05). Pulses in boys aged 7 - 9 years when BMI were P₅, P₅₀, P(95) were 87.63, 87.00, 87.83 times/min, and pulses in boys aged 10 - 12 were 85.66, 85.30, 85.43 times/min, respectively. Pulses in boys aged 13 - 15 years when BMI were P₅, P₅₀, P₉₅ were 82.60, 81.39, 82.34 times/min, and pulses in boys aged 16 - 18 years were 80.15, 79.00, 79.98 times/min. In both boys and girls of all age groups, weight vital capacity index had the trend of obese < overweight < normal-weight (P < 0.05). Compared to the normal-weight group, weight vital capacity index of overweight boys decreased by 6.4 - 8.4 ml/kg, that of obese boys decreased by 11.9 - 14.8 ml/kg, while that of overweight girls decreased by 5.3 - 7.7 ml/kg, that of obese girls decreased 11.0 - 11.5 ml/kg.

CONCLUSIONCompared to the normal-weight, overweight and obese children and adolescents had elevated blood pressure, increased pulse, decreased weight vital capacity index.
