Objective: The strategies against epilepsy are currently very limited. The author performed this work to determine the effect of electroacupuncture (EA) on epileptic seizures and define the optimal EA conditions (acupoints and stimulation parameters). Methods: Experimental epilepsy was induced by injecting kainic acid into the lateral cerebral ventricle of adult male SD rats. EA with a current of 1 mA/100 Hz or 1 mA/10 Hz was applied to the model starting at 0.5 h after the injection for 30 min. Four pairs of acupoints were tested, including Renzhong (GV 26) + Dazhui (GV 14), Jinsuo (GV 8) + Yaoqi (Ex-B 9), Neiguan (PC 6) + Quchi (LI 11) and Fenglong (ST 40) + Yongquan (KI 1). Results: Behavioral scores showed that (1) either high (100 Hz) or low (10 Hz) frequency EA at different acupoints attenuated epileptic seizures (P<0.05 or 0.01 vs. the control), except EA at Neiguan (PC 6) + Quchi (LI 11) with 1 mA/10 Hz current; (2) EA with low frequency stimulation (10 Hz) induced a better effect at Fenglong (ST 40) + Yongquan (KI 1) than other acupoints (P<0.05 or 0.01); (3) there was no significant difference in EA effects induced by various acupoints when exposed to high frequency EA (100 Hz); and (4) high frequency EA (100 Hz) elicited a better effect than low frequency EA (10 Hz) in all groups (P<0.05 or 0.01) except for that of Jinsuo (GV 8) + Yaoqi (Ex-B 9). EEG showed the similar tendency, i.e., EA generally reduced the amplitude and frequency of epileptic discharges. Conclusion: Electroacupuncture attenuates epileptic seizures, which is relatively specific to EA parameters and acupoints.

Kasabach-Merritt syndrome(KMS) is a massive haemangioma with thrombocytopenia and consumptive coagulopathy. The histopathology of KMS is thrombocytopenia and disseminated intravascular coagulation associated with massive haemangioma.A standard treatment regimen for KMS has not been established. Therapy includes surgery, embolism and medicine(steroids,α-interferon , immunosuppressant , etc).

Objective To investigate the value of diffusion-weighted magnetic resonance imaging (DWMRI) in gross tumor volume definition and localregional recurrence/distant metastasis prediction in nasopharyngeal carcinoma ( NPC). Methods From Jun. 2008 to Feb. 2011, each of 36 patients with or without Iocalregional recurrence and/or distant metastasis treated by intensity-modulated radiotherapy in our hospital was matched in this study. The difference of apparent diffusion coefficient ( ADC) values between these two groups was compared by t-test method. The conventional MRI and DWMRI before treatment were centrally reviewed to evaluated whether DWMRI would benefit to the definition of gross tumor volume.Results The mean ADC value were (0. 753 ±0. 091) x 10 -3 mm2/s and (0. 793 ±0. 094) x10-3 mm2/s in treatment failure group and control group, respectively ( t = - 1. 79 ,P = 0. 078) . The extension of gross tumor volume were much more outstanding in DWMRI when compared to conventional MRI. DWMRI predicted localregional recurrence more accuracy than conventional MRI in one patient . Conclusions DWMRI is help to definition of gross tumor volume. The ADC value before radiotherapy can not predict the localregional recurrence and/or distant metastasis for nasopharyngeal carcinoma.

Disruption of blood supply to the femoral head and subsequent hypoxia are implicated in the pathogenesis of osteonecrosis of the femoral head(ONFH),which frequently leads to the progressive collapse of the femoral head,thus causing degenerative arthritis of the hip joint.But the pathophysiology of osteonecrosis of the femoral head has not been completely elucidated.It is accepted that steroids and alcohol intake are two most common causes of ONFH.Now many theories have been proposed to decipher the etiology and pathogenesis of ONFH,including abnormal lipid metabolism,elevated intraosseous pressure,intravascular coagulation,second collision theory,etc.The purpose of this review is to summarize the etiology and pathogenesis of osteonecrosis of the femoral head.

[Objective]To investgate the expression of vascular endothelial growth factor in osteonecrosis of the femoral head during the repairing with biodegradable strontium-doped calcium polyphosphate in glucocorticoid-induced rabbits.[Method]Twenty mg/kg methylprednisolone was injected into right gluteus medius muscle at intervals of 24 hours for three times in 21 adult male Japanese white rabbits.Three rabbits were killed randomly at 2 weeks after methylpednisolone injection,both the femora and humeri were histologically examined for the presence of osteonecrosis. The remaining 18 animals with a total of 36 cylindrical 2.5?5 mm femoral head defects were created following the trapdoor procedure. Eighteen animals with femoral head bone defects were randomly divided into three groups. Group A:the defects filled with strontium-doped calcium polyphosphat,Group B:the defects filled with calcium polyphosphate and Group C:the defects filled with autologous cancellous bone alone. Roentgenographic and histological examinations were performed postoperatively. Finally,immunohistochemical analysis using monoclonal antibodies anti-VEGF was performed.[Result]No hip joint dislocation occurred. In Group A,the results of VEGF expression had a significantly difference from those in the other groups 12 weeks after operation. Most of the biodegradable strontium-doped calcium polyphosphate was resorbed and was largely replaced by newly formed trabecular bone at 12 weeks. While in Group B,a major part of defect were repaired. New formed trabecular bone in the defect was very thin. In Group C,morsellized cancellous bone was completely surrounded by fibrous and newly formed trabecular bone. [Conclusion]VEGF expression in the defect of osteonecrosis of the femoral head during the repairing with biodegradable strontium-doped calcium polyphosphate may play a role in stimulating vascular invasion and granulation tissue formation.This may be an important step toward facilitating the resorption in the osteonecrosis,thus impooring the repairing proceduce of femoral head defect.

B-Raf kinase (BRAF) gene is a driver mutation,and is an effective target in the treatment of non-small cell lung cancer (NSCLC).Studies have shown that BRAF inhibitors are effective for treatment of NSCLC with BRAF mutant.It is important to understand the clinicopathologic features and the research progress of BRAF inhibitors for the individual treatment of NSCLC.

Objective To investigate the protective effect of Danhong Injection(DI) on rats ischemia-reperfusion(I/R) injury after kidney transplantation.Methods Ten normal SD rats were allocated into the sham-operation group,and they were only been anesthetized and exposed kidneys for 45 minutes.The allogeneic male SD rats model of kidney transplantation were established.The qualified rats were divided into 3 groups(10 in each group)at random:I/R model group,DI pretreatment group,and DI treatment group.B1ood urea nitrogen(Bun) and creatinine(Cr) levels in each group were determined at the 24th hour after operation.The expression of Bax and Bcl-2 in kidney were quantitatively detected by immunohistochemistry.Apoptotic index was measured by TUNEL method.Results Compared with the sham-operation group,the apoptosis rate(P

Cerebral arteriovenous malformation is a common cerebrovascular disease.Its exact pathogenesis remains unclear.At present,it is thought that this disease is caused by kinds of factors,including congenital and acquired factors.

Nei Jing says:Tian Qi connects Lung. Cough is closely associated with the seasons’change of climate which means four seasons and six pathogenic factors,so we must combine the clinical treatment of cough with the seasons’change of climate,which conduct an overall analysis of the illness and the patient's condition. It is favorable to drive out pathogenic Qi and restore healthy one.

Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs)and anti-angio-genic drugs have individually demonstrated clinical benefit in the treatment of patients with advanced non-small cell lung cancer (NSCLC).Recent studies demonstrate that the combination of anti-EGFR and anti-angiogene-sis can more significantly enhance clinical benefit,and even can remit EGFR-TKIs resistance in the treatment of advanced NSCLC.According to the different kinds of anti-angiogenesis drugs,recent clinical studies mainly include the combination of anti-vascular endothelial growth factor monoclonal antibody bevacizumab plus EGFR-TKIs and multi-targeted receptor anti-angiogenic tyrosine kinase inhibitor plus EGFR-TKIs,and the for-mer results show a more significant improvement in terms of safety and efficacy in the treatment of advanced NSCLC.Therefore,the combination of bevacizumab plus EGFR-TKIs can be used as a new treatment standard in the treatment of some patients with NSCLC.
