ObjectiveTo investigate the changes in plasma myeloperoxidase (MPO), malondialdehyde (MDA), super-oxide dismutase (SOD) and total anti-oxidant capability (T-AOC) of Henoch-Sch?nlein purpura in children.MethodsA total of 80 HSP children hospitalized from November 2013 to April 2014 were selected including 40 cases of arthritis type, 20 cases of abdominal type and 20 cases of nephritis type (HSPN). Meanwhile, 16 healthy check-up children were selected as controls. Plas-ma MPO, T-AOC levels were detected by chemical colorimetry and MDA levels were detected by thiobarbituric acid colorime-try. Plasma SOD levels were measured by hydroxylamine method. Furthermore, 24-hour urine protein and other hematological indices were routinely tested.ResultsThe plasma levels of MPO, MDA, SOD and T-AOC were signiifcantly different among control group, arthritis type group, abdominal type group and HSPN group (F=24.22-126.99, allP=0.000). In comparison to oth-er three groups, the levels of MPO and MDA were signiifcantly increased and the levels of SOD and T-AOC were signiifcantly decreased in HSPN group (P<0.05). Compared with control group, the levels of MPO and MDA were signiifcantly higher and the levels of SOD and T-AOC were signiifcantly lower in arthritis and abdominal type groups (P<0.05). The levels of MPO and MDA in HSPN group were signiifcantly positively correlated with 24-hour urine protein (r=0.695, 0.559; bothP<0.01).Conclu-sionsThe imbalance between oxidation and antioxidant system exists in children with Henoch-Sch?nlein purpura.

Objective To explore the expression of angiopoietin-1 (Ang-1) and lung development in neonatal rat with hy-peroxia-induced bronchopulmonary dysplasia (BPD). Methods A total of forty-eight 1-to 3-day-old neonatal rats were random-ly divided into hyperoxia group and control group with 24 rats in each group, fed in high concentration oxygen (≥95%) or in air respectively. At 1st, 3rd and 7th day after high oxygen exposure, the histological changes in lung tissue were observed by HE stai-ning under a light microscope and the expressions of Ang-1 mRNA and its protein in lung tissue were detected by RT-PCR and Western blot. Results With extended exposure to high concentrations of oxygen, rats in hyperoxia group presented such patho-logic change of lung tissue dysplasia as alveolar simplification, reduction in alveolar number and arrested pulmonary microvas-cular development. At 7th day after high oxygen exposure, Ang-1 mRNA and protein expressions in hyperoxia group were (0.33± 0.18) and (0.20±0.07), significantly lower than those [(0.83±0.46) and (0.57±0.44)] in control group (P<0.05). Conclusions Ang-1 plays an important regulatory role in the pulmonary vascular development and participates in the pathogenesis of BPD.

Objective: To systematically evaluate the clinical effects of Maxing Shigan Decoction (MXSGD), a compound traditional Chinese herbal medicine, combined with Western medicine on pneumonia in children. Methods: In this study, the relative trials published from 1994 to 2008 were searched in Chongqing Weipu Database, Chinese Journal Full-text Database, Wanfang database, Chinese Biomedical Literature Database and other electronic database by using the method of Cochrane systematic review. At the same time the information from related journals, professional data and network were hand-searched. The methodological quality of the included trials was assessed by two evaluators, and homogeneous evaluation by meta-analysis was performed. Statistical analysis of clinical data was performed by using RevMan 4.2.7 software provided by the Cochrane Collaboration. Results: A total of 146 reports were found, while only eight randomized controlled trials met the inclusion criteria. The methodology quality of the reports included in the study was evaluated by the Jadad scale, and the specific random method, allocation concealment, blinding and intention-to-treat analysis were not described in all of the eight trial reports. As MXSGD combined with Western medicine group (treatment group) was compared with Western medicine group (control group), the meta-analysis indicated that the odds ratio for the total effective rate was 4.06, and the 95% confidence interval was from 2.63 to 6.27. MXSGD combined with Western medicine was good at increasing the total effective rate as compared with Western medicine, and the difference was statistically significant (P<0.000 01). Conclusion: MXSGD combined with Western medicine can improve clinical symptoms and increase the total effective rate of the patients with pneumonia in children. However, its clinical effects should be further identified by high quality, multicenter and randomized controlled trials with large-scale design.

Objective To inquire into the value of Liechtenstein Hernioplasty in the therapy of oblique or direct hernia.Method Liechtenstein was used in the therapy of 163 cases of oblique hernia (154 cases) and direct hernia (9 cases) from Feb.1998 to Jun.2001 and the clinical data was retrospectively studied.Most of them are of onset hernia except 8 cases of recurrent hernia.In 148 cases,the diameter of hernia ring is less than 2.5 cm and 30.1% of patients are elder than 65.The emergent operation was adopted in 12 cases.Results Off-bed exercises can be admitted at early stage of postoperation with slight pain and no local tension.Total recovery was obtained in 5-10 days after operation.After 6-36 months' follow-up,no mortality and less recurrence was detected.Conclusions There are so many advantages to treat oblique or direct hernia with Liechtenstein, such as minimized trauma, accelerated recovery,low recurrence rate and low cost. The indication of this operation involved all kinds of hernia (onset or recurrence of oblique or direct hernia,emergent operation of incarcerated oblique hernia, etc).

Objective:To identify the effect of ?-synuclein overexpression on mitochondrial membrane structure with atomic force microscopy. Methods:?-syn expression was mediated by AAV (adeno-associated viral vector) and Recombinant AAV/?-syn and AAV/LacZ viral particles were stereotaxically injected in the left side of rat substantia nigra (SN) for rat model of ?-synuclein overexpression. Mitochondria were isolated from rats SN of Brain. Mitochondria were analysis with JC-1 staining,atomic force microscopy and Western blot. Results:By 16 weeks post-infection of AAV-?-syn,the level of ?-syn increased about 2 times in mitochondrial fraction with Western blot and mitochondrial membrane potential (??) decreased with JC-1 staining. Furthermore,mitochondria swelling and porous like structure formed on the mitochondrial membrane with atomic force microscopy. Conclusion:The data suggested that ?-syn could accumulate in mitochondria,might form mitochondrial membrane pores and lead to ?? decreases. ?-syn might lead to mitochondrial dysfunction in Parkinson's disease.

Objective To explore the effects of vascular endothelial growth factor (VEGF) and nitric oxide (NO) on coronary collateral blood flow (CCBF) in a rabbit model of physical ischemic training (PIT),and to provide a foundation for the study of the mechanism of collateral circulation formation in PIT.Methods Models of intermittent myocardial ischemia were established in 55 rabbits by installing a water balloon constrictor on the left ventricular coronary artery.The rabbits were then divided into a sham-operation group,a pure ischemia group,a PIT group,a PIT group with NO inhibition pretreatment,a PIT group with VEGF inhibition treatment,and a PIT group with both NO and VEGF inhibition pretreatment.Microspheres were injected at modeling and before sacrifice before and after ischemic stimulation.At the termination of the experiment the ischemic myocardial tissue of the left ventricular anterior wall was sampled,and then relative CCBF was measured using the microspheres.Results There was no significant difference among the 6 groups before training.After training prominent differences among the groups were observed,with the PIT group having the greatest increase in CCBF.CCBF in the pure ischemia group,the PIT group,and the PIT group with NO inhibition pretreatment were significantly higher than in the sham-operation group.Significant differences were also found between the PIT group and the three pretreatment groups.CCBF in the PIT group with NO pretreatment and VEGF inhibition was significantly different from that in the NO pretreatment group,while it was not found in the group with VEGF inhibition pretreatment.The CCBF in the group with VEGF inhibition pretreatment and the group with NO inhibition pretreatment was similar.Conclusions PIT can improve CCBF to the remote ischemic myocardium when combined with VEGF and NO pretreatment.Blocking VEGF or NO can reduce CCBF after training,and both VEGF and NO are involved in the formation of collateral circulation,with VEGF playing the major role.
