Objective To observe the effects of different doses of Yinxingdamo injection on changes of nerve-specific enolase (NSE) of patients with medium-sized brain injury and discusse the mechanism of Yinxingdamo injection in the treatment of brain injury. Methods The contents of serum NSE in 33 cases of craniocerebral injury were dectected by ELISA test and the results were analyzed. Results NSE levels in patients with brain injury were significantly higher than normal people (p ＜0.05). Yinxingdamo injection can reduce the content of NSE for brain injury patients. This reduction related with the dosage of the medicine, showing the higher the dosage is used, the greater reduction may be.Conclusion Yinxingdamo injection can reduce NSE in serum of patients with brain injury, and this may be the mechanism of Yinxingdamo injection in treating craniocerebral injury.

The current situation of the rise in medical expenses is shown through statistics and the causes of the rise are analyzed. These include: ①inevitability of development, such as changes in the spectrum of diseases, use of new technologies and materials, rise in the overall price index, and generally increased needs for medical care; ②restriction of social factors, such as the imperfect medical insurance system, the reduced proportion of input by the government, the irrational medical pricing and compensation, the fictitiously high pricing of drugs and health materials, and the hospital's excessively high operational costs; ③the boosting effect of the "supporting medicine with drugs" policy. Countermeasures are put forward for the government's price control and financial organs, the departments of health administration, and the hospitals.

BACKGROUND:To maintain the long-term effect of ful crown largely depends on the health of periodontal tissues. OBJECTIVE:To explore the effect of CAD/CAM zirconia al-ceramic crown restoration on the state of periodontal health. METHODS:Sixty-four abutments of 55 patients were randomly divided into two groups:the experimental group included 32 abutments of 29 patients which would be restored by CAD/CAM zirconia al-ceramic crowns;the control ed group included 32 abutments of 26 patients which would be restored by Ni-Cr al oy porcelain-fused-to-metal restorations. The volume of gingival crevicular fluid and the levels of interleukin-6 and tumor necrosis factor-αin the two groups were examined at the pre-restoration and post-restoration stages. Meanwhile, periodontal clinical indicators, including sulcus bleeding index, probing depth, plaque index and attachment loss were recorded. RESULTS AND CONCLUSION:No difference in various indexes was found in the experimental group before and after restoration (P>0.05). At 12 months after restoration, in the control group, the volume of gingival crevicular fluid, the levels of interleukin-6 and tumor necrosis factor-α, sulcus bleeding index, probing depth, and plaque index were al increased (P>0.05);meanwhile, these indexes in the experimental group were significantly lower than those in the control group (P<0.05). Experimental findings suggest that the CAD/CAM zirconia al-ceramic crown restoration is more favorable to the health of periodontal tissues.

Objective To study the effects and mechanisms of myocardial injury in schistosome-infected mice.To investigate the effects and mechanisms of quercetin on myocardial injury due to the development of hepatic fibrosis after being treated by Praziquantel.Methods Eighty mice were divided into four groups:group A,group B,group C,and group D.Group A,group B,and group C were infected with Schistosoma japonicum cercariae.After 8 weeks,group A was treated with Praziquantel 500 mg/kg for 2 d,group B was treated with quercetin 30 mg/(kg?d) for 8 weeks after being treated with Praziquantel 500 mg/kg for 2 d.Group C was taken as experimental control without any treatment.Group D was taken as normal control.At the week 16,all mice were sacrificed and a part of liver tissue and myocardium tissue were preserved.HE Staining,electric microscope,RT-PCR,and immunohistochemical technique were applied to observing the changes of hepatic and cardiac histopathology,myocardial ultramicrostructure,the expression of myocardial c-fos,c-jun mRNA,and the contents of myocardial transforming growth factor-?1 (TGF-?1),typeⅠand typeⅢcollagen in mice infected with S.japonicum before and after treatments. Results There was different degree of myocardial injury among three groups of experimental control, Praziquantel treatment,Praziquantel combined with quercetin treatment.Praziquantel treatment relieved the degree of hepatic fibrosis and myocardial injury.The content of myocardial c-fos mRNA,c-jun mRNA,TGF-?1,typeⅠand typeⅢcollagen were obviously reduced compared to the experimental control. When Praziquantel treatment combined with quercetin,the degree of hepatic fibrosis and myocardial injury were further relieved.Although the content of myocardial c-fos mRNA,c-jun mRNA,TGF-?1, typeⅠand thypeⅢcollagen were still higher than those in normal control,those were reduced significantly compared to the group treated with Praziquantel.Conclusion Hepatic cirrhosis due to advanced schistosomiasis may lead to cardiac remodeling by stimulating the expression of immediate early gene and promoting the overexpression of TGF-?in myocardium.Anti-fibrosis therapy can reduce the degree of cardiac remodeling.Quercetin may protect myocardium through reducing the degree of hepatic fibrosis and inhibiting the expression of immediate early gene,which could decrease the level of myocardial TGF-?1.

Purpose To explore the clinical value of131I-whole body scan (131I-WBS) and 18F-FDG PET/CT on the metastatic management of patients with differentiated thyroid cancer (DTC) after operation.Materials and Methods Serum thyroglobulin (Tg) of 27 patients after DTC surgery was measured one day before131I therapy, and the patients underwent131I-WBS on 3-5 days after131I therapy. According to the results of Tg and 131I-WBS, all the patients were divided into 4 types as follows: type I: Tg (+),131I-WBS (-); type II: Tg (+),131I-WBS (+); type III: Tg (-),131I-WBS (+); and type IV: Tg (-), 131I-WBS (-). Then the patients received18F-FDG PET/CT scan within a week after 131I-WBS. The results of131I-WBS and18F-FDG PET/CT scan were analyzed according to histopathologic findings or clinical and imaging follow-up of at least 6 months as diagnosis standard.Results The examinations uncovered that metastasis occurred in 52 lesions of 22 cases out of the 27 cases.131I-WBS revealed 24 metastatic lesions (46.2%) in 8 cases (36.4%), and18F-FDG PET/CT showed 35 metastatic lesions (67.3%) in 15 cases (68.2%), the difference with statistic significance (χ2=4.46 and 4.74,P<0.05). Metastasis were confirmed in 13 type I cases (100.0%); 5 type II cases (100.0%); 3 type III cases (100.0%) and 1 type IV case (16.7%), respectively. The rate of detecting metastasis by 18F-FDG PET/CT was 100.0% in type I, 20.0% in type II, 0% in type III respectively, the difference with statistic significance (χ2=9.14 and 10.11,P<0.05); and 100.0% in type IV, the difference without statistic significance (χ2=1.25,P>0.05). Based on that, therapeutic plans were modified for 13 patients with type I metastasis and 1 patient with type IV metastasis.Conclusion131I-WBS and18F-FDG PET/CT are complementary for detecting metastatic lesion and help to decide the following treatment of DTC patients after surgery. Moreover,18F-FDG PET/CT shows advantages in detecting metastatic lesion in Tg-positive and negative131I-WBS type of DTC patients after surgery, thus can provide an important clinical guidance for this type of patients.
