Objective To evaluate the efficacy of potassium sodium dehydroandroan drographolide succinate (PSDS) combined with routine therapy for rotavirus enteritis in children.MethodsA total of 148 children with rotavirus enteritis were included and divided into an observation group and a control group by random number table method, 74 in each group. The children in the observation group were treated with intravenous PSDS combined with routine therapy, and those in the control group with intravenous ribavirin combined with routine therapy. Serum interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were determined by enzyme-linked immunosorbent assay, and plasma lactate dehydrogenase (LDH), creatine kinase (CK), and creatine kinase-MB (CK-MB) were determined using standard clinical laboratory procedures. The clinical efficacy was evaluated. Results The total efficacy rate in the observation group was significantly higher than that in the control group (91.9%vs. 78.4%;χ2=2.314,P<0.05). After the treatment, the serum levels of IL-6 (18.24 ± 3.62 ng/mlvs. 25.36 ± 5.25 ng/ml; t=2.425,P<0.05) and TNF-α (20.86 ± 4.28 ng/mlvs. 31.22 ± 7.15 ng/ml;t=2.503,P<0.05), and the plasma levels of LDH (104.25 ± 22.06 U/Lvs. 150.26 ± 37.22 U/L;t=2.316,P<0.05), CK (84.25 ± 13.57 U/Lvs. 107.88 ± 16.28 U/L;t=2.327,P<0.05) and CK-MB (22.30 ± 4.24 U/Lvs. 32.26 ± 7.14 U/L;t=2.426,P<0.05) in the observation group was significantly lower than those in the control group. The time to diarrhea resolution (2.42 ± 0.53 dvs.3.56 ± 0.78 d;t=2.316,P<0.05) and the time to fever resolution(2.11 ± 0.32 dvs.2.63 ± 0.43 d;t=2.472,P<0.05) in the observation group were significantly delayed than those in the control group, and the hospital length of stay longer (6.23 ± 1.42 dvs. 4.35 ± 0.96 d;t=2.413,P<0.05).Conclusions PSDS combined with routine therapy may reduce inflammatory response, protect from myocardial injury, and promote recovery in children with RVE.

BACKGROUND:Reduction quality is essential for the healing and function of limb. Traditional X-ray and CT scans have some limitationsin quantitatively and visualy observing the reduction quality of the remnant fracture in three-dimensional displacements. Mimics have advantages in bone rapid modeling and three-dimensional measurement, which offers the chance in quantifying the reduction quality of the displacement in three-dimensional methods.
OBJECTIVE:To measure residual displacement in femoral neck fracture patients with satisfactory reduction by using three-dimensional measurement method, and to evaluate the association between residual displacement and femoral head necrosis.
METHODS:We enroled 141 patients with femoral neck fracture, who were treated in the Third Department of Joint, Affiliated Hospital of Logistics University of People’s Armed Police Force from January 2012 to December 2013. Al patients were divided into undisplaced fracture group (n=44; Garden1&2) and displaced fracture group (n=97; Garden3&4). Based on DICOM data of CT files, three-dimensional models were constructed in each patient. Three parameters were measured: displacement of femoral head’s center, fossa capitis femoris and rotational displacement. Femoral head necrosis was folowed up. The correlation between residual displacement and femoral head necrosis was explored.
RESULTS AND CONCLUSION:(1) The duration of folow-up in those patients ranged from 25 to 43 months. Femoral head necrosis occurred in 7 cases from the undisplaced fracture group and 21 cases from the displaced fracture group. (2) The three parameters (displacement of femoral head’s center, fossa capitis femoris and rotational displacement) were respectively (7.44±2.84) mm, (11.75±4.12) mm and (17.68±8.99)° in the undisplaced group, and (6.51±3.75) mm, (9.34±5.27) mm and (14.67±7.43)° in the displaced group. Except displacement of femoral head’s center, significant differences in the other two parameters were detected between the two groups (P< 0.05). (3) These findings suggest that poor reduction quality is the main factor causing femoral head necrosis. X ray is insufficient to describe the spatial shift and the angle, and has limitations in assessing the reductionquality of femoral neck fracture. Three-dimensional measurement has certain advantages to assess quality of fracture reduction.

Objective To observe the influence of exercises on the mRNA expression of peroxisome proliferator-activated receptor (PPAR-α) and its target genes of acyl-CoA oxidase (ACO),Enoyl-CoA-hydratase and 3-hydroxyacyl-CoA-dehydrogenase (EHHADH) in the skeletal muscles in insulin-resistance mice to develop a way to improve the lipid metabolism.Methods Twenty male ApoE knockout mice were randomly divided into two groups,the high-fat diet group (group HFD) and the exercise training group (group Ex).The HFD group were fed with highfat diet,while the Ex group were fed in the same way,with additionally swimming training.And ten healthy male C57BL/6j mice were chosen as the control group(group ND).After 12 weeks of intervention,the serum lipid,blood glucose and insulin levels were determined,and homeostasis model assessment insulin resistance index (Homa-IRI) was calculated.The bilateral gastrocnemiuses were cut to be observed under a transmission electron microscope,and the mRNA expression of PPAR-α,ACO and EHHADH in skeletal muscle were measured using reverse transcription polymerase chain reaction(RT-PCR).Results The transmission electron microscope showed that the sarcolemma edema,mitochondrial swelling,as well as focal myocytolysis and edema within myofibrils were observed in the HFD group.The total cholesterol,low-density lipoprotein cholesterol,free fatty acid,fasting glucose,insulin and HomaIRI of the HFD group were significantly higher than the control group (P < 0.05),while the mRNA expression of PPAR-α,ACO and EHHADH was significantly deceased than the latter(P < 0.05).After swimming,the abovementioned pathological changes disappeared.The serum lipid of the Ex group were significantly lower (P < 0.05),while HDL was significantly higher (P < 0.05).And fasting insulin,glucose and HOMA-IR of the Ex group were significantly lower (P < 0.05),while the mRNA expression of the above in the Ex group were significantly increased (P <0.05).Conclusion Swimming training could improve insulin resistance and metabolic disorder of lipid of ApoE knockout mice.The possible mechanisms may be through up-regulating the expression of PPAR-α,which in turn stimulates the expression of ACO and EHHADH mRNA to strengthen fatty acid β-oxidation.

Aim: To determine the uptake characteristics of salvianolic acid B(Sal B) in myocardial cells and blood vessel endothelial cells. Method: The effects of various factors, such as time, temperature, drug concentration, pH of the medium, on the uptake of Sal B in myocardial cells and aorta endothelial cells were investigated. LC/MS was employed to determine the intracellular concentration of Sal B. Results: Uptake kinetics of Sal B in the myocardial cells and aorta endothelial cells fitted well to the logarithmic model at 37 ℃ and 4 ℃. The a-mount of uptake was in direct proportion to the extracellular concentration of Sal B in the experimental concentration range. Uptake of Sal B both in the myocardial cells and blood vessel endothelial cells would significantly increase while the medium pH decreased, and some water-soluble components extracted from danshen would also facilitate the uptake of Sal B both in the myocardial cells and blood vessel endothelial cells obviously. The energy metabolism inhibitors would significantly inhibit the uptake of Sal B in the myocardial cells and blood vessel endothelial cells. When lactic acid and fatty acid were added to the incubation solution, the uptake of Sal B both in the myocardial cells and aorta endothelial cells increased more than 20%. Conclusion: pH is the most important factor influencing the cellular uptake of Sal B, and the amount of uptake tends to increase in acidic medium. Results suggest that the uptake of Sal B would increase in the acidified internal environment induced by myocardial ischemia, thus exerting better cardiovascular activities.
