BACKGROUND:Denis B thoracolumbar burst fractures are common spinal injury and may be involved in the upper end plate injury. Fracture reduction and pedicle screw fixation are used to repair above injury. This scheme can effectively achieve the aim of correcting deformity, but the trabecular bone after crushing cannot be fuly recovered. OBJECTIVE:To observe the repair effect of fracture reduction and pedicle screw fixation + artificial bone graft in vertebral body on Denis B thoracolumbar burst fracture, and compare with fracture reduction and pedicle screw fixation alone. METHODS:Clinical data of 70 cases of Denis B thoracolumbar burst fractures, who were treated in the Department of Orthopedics, Zhangjiagang Aoyang Hospital from January 2012 to December 2014, were retrospectively analyzed. According to repair scheme, they were equaly divided into two groups. Patients in the control group received fracture reduction and pedicle screw fixation. Patients in the observation group received fracture reduction and pedicle screw fixation + artificial bone graft in vertebral body. Oswsetry Disability Index, height of anterior border of injured vertebral body, lower back pain visual analogue scale and vertebral kyphosis Cobb’s angle were compared and observed between the two groups before repair, 1 week, 3 and 6 months after repair. RESULTS AND CONCLUSION:No significant difference in Visual Analogue Scale was detected at 1 week, 3 and 6 months after repair between the observation and control groups (P > 0.05). Oswsetry Disability Index was significantly lower in the observation group than in the control group (P < 0.05). No significant difference in the height of anterior border of injured vertebral body was detected between the observation and control groups (P > 0.05). Cobb’s angle was significantly lower in the observation group than in the control group (P < 0.05). These findings suggest that fracture reduction and pedicle screw fixation + artificial bone graft in vertebral body obtained good repair effects on Denis B thoracolumbar burst fracture, not only effectively corrected Cobb’s angle and the height of anterior border of injured vertebral body, but also helped to restore normal spinal loads by filing bone in the injured vertebral body.

Objective To explore a more reasonable and effective therapeutic regimen and evaluate prognostic factors in hepatoblastoma patients after combined therapy.Methods Sixteen patients diagnosed on hepatoblastoma between Jan.2000 and Nov.2007 were reviewed and followed-up.Resection with chemotherapy was taken among 16 cases.Chemotherapy included pre-operation and post-operation.Five cases were cured by transcatheter arterial chemombolization(TACE).Six cases were cured by single chemotherapy(both TACE and single chemotherapy were taken in 2 cases).Five cases weren't cured by pre-operation chemotherapy.Nine cases were subjected to curative resection,3 cases to alleviative resection,2 cases with single chemotherapy,1 case with single TACE,and 1 case refused operation and left hospital.Their mean survival duration was 13.5 months(3-98 months).SPSS 13.0 software was used to analyze the data.Results The total survival rate of cases as stage Ⅳ as lower than cases as stage Ⅰ,Ⅱand Ⅲ.Both alpha-fetoprotein(AFP)100 000 ?g/L cases had worse survival rate.The prognosis of mixed type was better than fetal type,embryonal type and anaplasia type.The survival rate of cases with standard chemotherapy was higher than cases with unstandard chemotherapy.And the surgical resection cases had better survival chance than non-surgical resection cases.The survival rate of surgical residual cases was worse than non-surgical residual cases.Conclusions Chemotherapy can improve the total survival rate and long-term survival rate of hepatoblastoma patients.TACE is a safe and effective choice for hepatoblastoma patients.We need to be alert and make the diagnosis as early as possibe,and treat it early and properly.

Hypoxia-inducible factor-1 (HIF-1) is a key transcription factor on hypoxia responses in mammalian tissues. HIF-1 plays as a positive factor in solid tumor and leads to hypoxia-driven responses that enhance its downstream gene expression for tumor growth and survival. LXY6099 was obtained by the structural modification and optimization of manassantin A (MA) as a high potent HIF-1 inhibitor. Antitumor activity of LXY6099 was observed in this study. LXY6099 with an IC50 value of 2.46 x 10(-10) mol x L(-1) showed more sensitive inhibition activity to HIF-1 than that of MA detected by reporter gene assay (> 100 folds). It showed strong inhibition on the growth of human solid tumor cell lines. Furthermore, LXY6099 exhibited significant antitumor activity against established human tumor xenografts in nu/nu mice with treatment of MX-1 breast cancer. Thus, LXY6099 as a novel HIF-1 inhibitor could be further developed into anti-cancer agents.

It is now thought that atherosclerosis,although due to enhanced lipid deposition,is mainly the result of a series inflammatory process.Total saponins of Aralia elata (Miq)Seem(TASAES)from the Chinese traditional herb Longya Araliachinensis L.,a folk medicine used for treating various diseases, increasing energy and improving the body′s ability to prevent hypoxia in Asian countries has attracted widespread attention. However, the ability of TASAES on inflammation-triggered vascular endothelial cell injury, a key early event in the pathogenesis of atherosclerosis, and its potential mechanisms of this protection have never been demonstrated. The present study determined the anti-inflammatory and anti-apoptoticactivities and protective mechanisms of the total aralosides of Araliaelata(Miq)Seem (TASAES) ameliorate tumor necrosis factor-α (TNF-α)-induced human umbilical vein endothelial cells (HUVECs) injury. Our results indicate that TASAES pretreatment provided cytoprotective effects by suppressing TNF-α-induced HUVECs apoptosis, mitochondrial membrane depolarization, caspase-3 activation, and modulation of inflammatory factors (IL-6, MCP-1 and VCAM-1), meanwhile inhibiting NF- κB transcription. Furthermore, the effect was correlated with the activation of the PI3K/Akt signal pathway. Blocking Akt activation with the PI3K inhibitor LY294002 effectively reversed the protective effect of TASAES against TNF-α-induced cell apoptosis.Moreover,the PI3K inhibitor partially blocked the effects of TASAES on the increasing of Bcl-2 and Bcl-xl protein expression,and inactivation of Bax protein expression. In conclusion, the results showed that TASAES decreased the inflammation and apoptosis of HUVECs caused by TNF-α treatment,and PI3K played a crucial role in enhancing cell sur-vival during this process.

Objective: To observe the clinical efficacy of spleen-invigorating and qi-benefiting pediatric massage (tuina) for treating recurrent respiratory tract infection in children with cerebral palsy due to qi deficiency of spleen and lung. Methods: A total of 70 children with cerebral palsy who suffered from recurrent respiratory tract infection due to qi deficiency of spleen and lung were randomized into an observation group and a control group by the random number table method, with 35 cases in each group. Both groups were treated with conventional rehabilitation training, while the observation group was given additional spleen-invigorating and qi-benefiting pediatric massage, and the control group additionally took oral Yu Ping Feng granule. The clinical efficacy was evaluated by the total effective rate, traditional Chinese medicine (TCM) symptom score, and serum levels of immunoglobulin (Ig) A, IgM and IgG. Results: The difference in total effective rate between the two groups after treatment was statistically significant (P<0.05). After treatment, the TCM symptom scores in both groups decreased to varying degrees than those before treatment, and the intra-group differences were statistically significant (all P<0.01); the differences in the scores of various TCM symptoms between the two groups were statistically significant (all P<0.05). After treatment, the levels of IgA, IgM and IgG of the children in both groups increased to varying degrees, and the intra-group differences were statistically significant (all P<0.05). The between-group differences in the IgA, IgM and IgG levels after treatment were statistically significant (all P<0.05). Conclusion: Spleen-invigorating and qi-benefiting pediatric massage can effectively treat recurrent respiratory tract infection due to qi deficiency of spleen and lung in children with cerebral palsy, relieve the clinical symptoms and improve immune function, and thus is worthy of clinical promotion and application.
