Objective To compare treatment and efficacy of thoracolumbar fractures by using three different screw fixations:traditional approach,the vertebral side clearance into the road and percutaneous pedicle. Methods A total of 82 single segmental thoracic lumbar fractures cases hospitalized from March 2011 to March 2014 ,with male 67 cases ,female 15 cases ,and average age(33.7+/-12.5)years old. Patients were randomly divided into three groups:traditional approach group (n = 23),operation through paraspinal muscle gap group (n = 30),percutaneous group(n = 29). These following indicators will be compared in three groups:duration of operation ,intraoperative blood loss ,intraoperative fluoroscopy time ,postoperative flow ,VAS scores before and after operation and Oswestry disability index , difference of spinal sagittal position Cobb′s Angle. Results Compared with the traditional approach group ,operation through paraspinal muscle gap group and percu-taneous group have obvious advantages in duration of operation,intraoperative blood loss,postoperative flow,VAS scores before and after operation ,the Oswestry disability index. Additionally ,above mentioned three surgical methods could recover kyphosis deformity ,and there was no statistically significant difference among three groups (P > 0.05). Conclusion In the treatment of monosegmental thoracolumbar fractures ,compared with traditional approach ,operation through paraspinal muscle gap and percutaneous pedicle screw internal fixation have more advantages which includes fewer trauma,less bleeding,faster recovery and lower incidence of postoperative low back pain.

This article was aimed to study the effect of Baohe granules for patients with chronic heart failure (CHF) of traditional Chinese medicine (TCM) syndrome and the effect of gastrointestinal hormone secretion. Patients with CHF were used as the object of study. A total of 80 selected patients were divided into 2 groups. The control group was treated with western medicine anti-heart failure therapy. The treatment group was treated with the combination of Baohe granules. All patients were compared in aspects of TCM efficacy, symptom score and serum gastrin, motilin secretion after two-week medication. The results showed that both treatments can significantly improve the TCM syn-drome and symptom total score of CHF patients. And the effect of the treatment group with Baohe granules was bet-ter. The TCM single symptom integral was also obviously improved in the treatment group combined with Baohe granules, which included heart palpitations, shortness of breath, abdominal distension, and loss of appetite. The GAS and MTL levels of CHF patients were significantly increased in the treatment group. It was concluded that the treat-ment combined with Baohe granules can improve CHF patients with TCM syndromes, symptoms and gastrointestinal hormone secretion. Thus, it contributed to the stability of the disease condition. It can slow the disease progression and improve prognosis. So it is worth using widely in the clinical practice.

Aim To investigate the effect of sphingo-sine kinase 1 (SphK1 )on unilateral ureteral obstruc-tion(UUO)-induced tubulointerstitial fibrosis and ex-plore the possible mechanism.Methods The CD-1 mice were randomly divided into four groups:sham-op-eration group(Sham),PF-543 treatment control group (Sham +PF-543),model group(UUO)and PF-543 treatment group(UUO +PF-543).On 1 ,3,7 and 1 4 d after operation,eight mice were selected randomly from each group and sacrificed.The protein expressions of SphK1 ,mature TGF-β1 ,FN,ColⅠ,LC3,Beclin1 ,Atg5 and Atg1 2 were observed by Western blot.The histo-logical changes were examined by Masson′s trichrome stain.Immunhistochemistry was performed to measure the levels of expression of SphK1 ,FN and Col Ⅰ. Transmission electron microscope was used to observe the autophagic body.Results SphK1 expression and autophagy were both upregulated in a mouse model of kidney fibrosis induced by UUO. Meanwhile, in-creased mature TGF-β1 and deposition of extracellular matrix(ECM)were observed in tubulointerstitial areas compared with sham-operated mice.After intraperito-neal injection with the SphK1 specific inhibitor PF-543 in UUO mice,enhanced expression of SphK1 and acti-vated autophagy were significantly abrogated.Howev-er,aggravation of renal fibrosis was detected when SphK1 inhibitor PF-543 was applied to suppress SphK1 expression in UUO mice.Conclusion SphK1 activa-tion is renoprotective through the induction of autoph-agy in the pathogenesis of kidney fibrosis.

Objective To study the effect of platelet-derived growth factor(PDGF)and lysosomes on lung injury in macaque with early-phase endotoxie shock.Method Eleven macaques were randomly divided into two groups,namely,control group(Co group,n=5)iand endotoxic group(En group,n=6).The macaque of the Co group injected with 1 ml/kg normal saline and the macque of the En group received a dose of 2.8 mg/kg Lipopolysaccharides(LPS)i.v.The blood gas was detected at 120 minutes after LPS challenging. Uhrastructure,cytochemistry of acid phosphatase(ACPase)detection by electronic microscopy and immunohistochemical assay of PDGF were completed in hmgs of all the macaque .Results Administration of LPS did not change the parameters of gas exchange,namely,PaO_2,PaO_2/Fi and PaCO_2.In the early phase,of endotoxic shock,ACPase activity products increased and lysosome destroyed in the alveolar cells.The pathologic changes of alveolus,such as degeneration of vessel endothelium,injury of alveolar epithelium and damage of basement membrane,and transudation of blood component were observed by electron microscopy in the En group. However,no pathological changes were found in the control group.By immunohistochemical staining,PDGF on alveolar wall in the En animals was observed,whereas no PDGF protein in the Co macaques was noticed. Conclusions Administration of LPS induced the expression of PDGF in the alveolar wall and lysosome injury in the alveolar cells,as a result of alveolar damage in early-phase endotoxin shock.In the meantime,the parameters of gas exchanges did not change.The PDGF may play an important role in the pathogenesis of lung during the early-phase of endotoxin shock.
