BACKGROUND:The pathogenesis of steroid-induced osteonecrosis of the femoral head remains unclear. Femoral head reconstruction after colapse is related to the bone remodeling due to disorder of the bone formation-absorption coupling. “Removing Blood Stasis” Method has been shown to have a positive effect on the disease in clinics. However, the mechanisms by which the “Removing Blood Stasis” Method confers bone repair after osteonecrosis remain poorly understood.
OBJECTIVE:To explore the effect of “Removing Blood Stasis” Method on bone repair in rabbits with steroid-induced femoral head osteonecrosis.
METHODS: Fifty New Zealand rabbits were randomly assigned into three groups: normal control (n=10),
model (n=20) andTaohong Siwu Decoction (n=20) groups, respectively. The steroid-induced osteonecrosis of the femoral head animal models were established by intramuscular injection of endotoxin combined with methylprednisolone (MPS). Rabbits inTaohong Siwu Decoction group were intragastricaly administered with 0.3 g/kg ofTaohong Siwu Decoction suspension after the last injection of methylprednisolone. The control and model groups were administrated by equal volume of ultrapure water for 8 consecutive weeks. High-resolution MRI and pathological determinations were used to assess the successful models. Protein expression levels of ABCB1, RUNX2, OPN, RANK, RANKL, PPAR, osteoprotegerin (OPG), vascular endothelial growth factor (VEGF) in rabbit femoral heads were detected by western blot assay.
RESULTS AND CONCLUSION:(1) Hematoxylin-eosin staining showed that trabecular bone fracture, karyopyknosis, empty lacunae, necrotic bone marrow cels were seen in the model group. Empty lacunae rate in the model group was significantly different from that in the normal control group (P < 0.05). Bone formation was active and kept better trabecular morphology in theTaohong Siwu Decoction group. It suggested that “Removing Blood Stasis” Method can improve repair of necrotic area. (2) In the model group, femoral head with a wide range of low-density areas in high-resolution MRI;Taohong Siwu Decoction group showed the relatively normal shape of the femoral head with smal areas of low density. It suggested that “Removing Blood Stasis” Method can improve image changes in the necrotic area. (3) Protein expression levels of RUNX2, RANK, RANKL were significantly up-regulated but protein expression levels of ABCB1, OPG, VEGF were significantly down-regulated in the model group compared with the normal control group; whereas, they were al significantly up-regulated in theTaohong Siwu Decoction group compared with the model group, except for RANK and RANKL (P < 0.05). These results suggest that the “Removing Blood Stasis” Method can promote bone repair in steroid-induced femoral head osteonecrosis rabbits by regulating protein expressions of ABCB1, RUNX2, RANK, RANKL, OPG, and VEGF.

Objective To detect the epidemiologic features of pediatric patients with fall from height injury in an effort to provide a reference for prevention and scientific treatment.Methods Data of pediatric patients with fall from height injury treated from January 2011 to December 2012 were collected in the form of questionnaires.Epidemiologic features and relationship of associated factors were measured.Results Pediatric fall injury occurred very often in warmer season,namely on April and May,and in a day,it was more likely to happen when parents slacked at noon and night.Stairs and balconies were the most common sites of falls and head was most vulnerable to the injury.Falling height was the primary factor to the severity of injury.Conclusion To strengthen the protection reform in key areas,the supervision in peak time for falls and the care to children of the migrant workers can reduce fall injury in a certain extent.

Objective To investigate the relationship between different topographic locations and neurological deteriorations (ND) in patients with acute new isolated pontine infarction.Methods One hundred sixty-eight patients with acute new isolated pontine infarction during arch 2012 to March 2016 were identified by diffusion weighted imaging (DWI) for retrospective review.Patients were divided into two groups according to their clinical symptoms:patients with ND and patients without ND.According to neuroimaging of DWI,the topographic location of pontine infarction was divided into three types:The upper,middle,and lower ones,and the correlations of ND with risk factors,laboratory examination results,clinical manifestations and different topographic locations were explored by statistical tests.Results Of 168 patients,26.8％ (45/168) were diagnosed with ND,and 73.2％ (123/168) were diagnosed without ND.Univariate analysis showed that there were differences in female ratio [62.2％ (28/45) vs 41.5％ (51/ 123)],smoking ratio [13.3％ (6/45) vs 26.0％ (32/123)],mean length of hospital stay [(22.83 ± 7.12)d vs (19.31 ± 7.65)d],ratio of worse short-term clinical outcomes [77.8％ (35/45) vs 33.3％ (41/123)],and ratio of lower pontine infarction [55.6％ (25/45) vs 26.0％ (32/123)] between two groups (P ＜ 0.05).Logistic regression analysis showed that lower pontine infarction was the independent risk factor of ND (OR =1.953,95％ CI:1.092-3.535,P =0.029).Conclusions Topographic location of lower pons lesions may be reliable predictor of ND in acute new isolated pontine infarction.

Objective To analyze the correlation between clinical features and renal dysfunction in patients of acute lacunar infarction with progressive cerebral microbleeds (CMBs). Methods Two hundred and sixty-five patients with first-episode acute lacunar infarction were selected. The serum creatinine was measured within 24 h of admission and the estimated glomerular filtration rate (eGFR) was calculated. The brain MRI (including gradient-echo images) was examined within 2 d of admission and after 1 years of follow-up, respectively. The progressive CMBs was assessed with microbleeds anatomical rating scale (MARS), and the patients were divided into progressive CMBs group (progressive group, 42 cases) and non progressive CMBs group (non progressive group, 223 cases). The clinical features of 2 groups were compared and the correlation between progressive CMBs and renal dysfunction was analyzed. Results The age, 24 h pulse pressure, incidences of renal dysfunction and CMBs in progressive group were significantly higher than those in non progressive group: (69.8 ± 5.8) years vs. (61.5 ± 4.9) years, (63.3 ± 3.1) mmHg (1 mmHg=0.133 kPa) vs. (51.8 ± 4.2) mmHg, 69.0％(29/42) vs. 39.9％(89/223) and 57.1％(24/42) vs. 25.1％(56/223), and the platelet was significantly lower than that in non-progression group:(168 ± 35) ×109/L vs. (189 ± 40) ×109/L, and there were statistical differences (P<0.05 or<0.01). The Logistic regression analysis result showed that renal dysfunction and CMBs were Independent risk factors of progressive CMBs (OR = 1.571 and 1.054, 95％ CI 1.042 - 2.493 and 1.010 - 1.142, P<0.05). Conclusions The rate of renal dysfunction is higher in patients of acute lacunar infarction with progressive CMBs, and progressive CMBs are associated with renal dysfunction.

This study was aimed to diffuse the lung and promote urination for the observation of cardiopulmonary re-lated index change of cor pulmonale rats to further explore the treatment effect on the pulmonary function, pulmonary arterial hypertension (PAH) and the influence of right heart hypertrophy of rats, in order to further illustrate the ef-fect of diffusing the lung and promoting urination for cor pulmonale. Sixty Wistar rats were randomly divided into the control group, model group and Xiao-Qing-Long decoction (XQLD) group with 20 rats in each group. The AniRes2003 animal lung function analysis system was applied to measure the pulmonary function of rats. And the multi-guide physiological recorder was used in the recording of the pulmonary artery pressure of rats. The conven-tional weighing method was applied to calculate and obtain the change of right heart hypertrophy. The results showed that compared to the control group, symptoms in the model group became severe obviously, which include reduced activity, slow movement and occasional airway sputum sound, and the right heart hypertrophy index of the model group increased obviously (P < 0.01). Compared to the model group, the pulmonary function and pulmonary artery pressure of the XQLD group have obvious difference (P< 0.05). It was concluded that to diffuse the lung and pro-mote urination can effectively improve the pulmonary function, PAH and the right heart hypertrophy index of rats with cor pulmonale (fluid retention). The effect of this method is definite in the treatment of cor pulmonale.

OBJECTIVETo discuss whether asiaticosides could effectively reduce the endothelial cell damage as a biochemical modulator, so as to further inhibit the post-stenting intima-media membrane hyperplasia.

METHODHuman aortic smooth muscle cells and aortic fibroblasts were selected and divided into the blank group, the rapamycin group and the asiaticoside group and the rapamycin and asiaticoside group. The expressions of muscle cells and fibroblasts TGF-beta1, Smad7 and I-collagen gene were determined by RT-PCR. The expression quantity of I-collagen protein was assayed by ELISA. The coefficient of drug interaction (CDI) between rapamycin and asiaticoside was calculated. Additionally, 16 Chinese mini-swines were randomly divided into group A and group B. One sirolimus drug-eluting stent of the same type was implanted after the high-pressure pre-expansion of anterior descending artery balloon. After the operation, the group A was intravenously injected with normal saline 30 mL x d(-1). Whereas the group B was intravenously injected with asiaticoside 30 mg x kg(-1) x d(-1)(diluted to 30 mL). The expressions of plasma vWF of the two groups were measured at the 7th and 14th days after the operation. At the 28th day after the operation, tissues of the stented vessel segments were sliced and stained to calculate the vessel area, inner stent area, lumen area and neointima area

RESULTCompared with the control group, the combination group showed significant up-regulation in smooth muscle cells and fibroblast Smad7 gene, down-regulation in TGF-beta, and obvious inhibition of I-collagen gene expression (P < 0.01). As for smooth muscle cells, there was no difference in the expression of I-collagen between the combination group and the rapamycin group, with CDI at 0. 83. As for fibroblasts, there was a significant difference in the expression of I-collagen between the combination group and the rapamycin group (P < 0.05), with CDI at 0.77. Plasma vWF of the group B was significantly lower than that of the group A (P < 0.05) at the 7th and 14th days after the operation. At the 28th day after the operation, no difference was observed in vessel area and stent area between the two groups. However, the lumen area in the group B was significantly larger than that of the group A(P < 0.05), and the neointima area of the group B was significantly smaller than that of the group A (P < 0.05).

CONCLUSIONAs an effective biochemical modulator for rapamycin, asiaticosides could inhibit TGF-beta expression, significantly decrease the synthesis and secretion of extracellular matrix, further inhibit the post-stenting intima-media membrane hyperplasia and reduce the endothelial cell damage by effectively up-regulate the expression of Smad7 protein.
