It is believed thatTraditional Chinese medicine treatment for the children with adenoid hypertrophyhas showed better curative effect and less side effects, which can reduce the operation rates. It's easy for parents and children to accept and can be widely promoted in clinical.

The family of bone morphogenetic proteins (BMPs) belongs to the superfamily of transforming growth factor-β (TGF-β). It has various functions in the body. In recent years the BMPs family(especially the BMP7) has been discovered to play an important role on the genesis and development of cancer. In this article the characteristic, the mechanism and the function of BMP7 in the genesis and development of cancer are summarized.

The arterial supply of the human metatarsals in 90 lower limbs,ranging in age from newborn to87 years,was studied by perfusion method. The blood supply of the metatarsals is derived from the nutrient artery,the periosteal arteries,the epiphyseo-metaphyseal arteries and the pseudoepiphyseal arteries. The proximal and distal branches of the nutrient artery supply the inner two-thirds or three-fourths of the cortex. The periosteal arteries give off a few twigs penetrating into the cortex and supplying the outer one-third or one-fourth of the cortex. The radiate form epiphyseo-metaphyseal arteries derived from superficial plexuses in continuity with the periosteal networks on the shafts, supply the base of the first metatarsal, and the heads of the other four. The pseudoepiphyseal arteries, penetrating the non-articular areas of the bones, supply the bases of the second, third, fourth and fifth metatarsals and the head of the first. The sources of the nutrient arteries to the metatarsal vary with the different bone . The nutrient arteries to first metatarsal bone usually originate from the ramus plantaris profundus and the first plantar metatarsal artery, while the nutrient arteries to the other metatarsal bones mainly derive from the plantar metatarsal arteries, the plantar arch and its perforating branches. The clinical significance of the arterial distribution to the metatarsals is discussed.

OBJECTIVE:To study the legislative evolution and causes of biologics data protection system in the United States, and provide reference for designing biologics data protection system in China. METHODS:Started from analyzing the features of biologics data protection in the United States,through analyzing the legislative struggle of biologics data protection in the United States,the caused and its enlightenment to China were explored. RESULTS & CONCLUSIONS:After legislative discussion evolu-tion and struggle,the United States enacted the Biologics Price Competition and Innovation Act in 2010,established the world's firststrong protectionstandard of biologics data protection system,and determined the 12-year data protection period. The legisla-tive basis was to stimulate the strategic needs of innovation,the direct cause was that a biological analogue simplified application was established in the United States,and the key factors included biologics technical attributes and patent protection features. Cur-rently,biologics data protection system is not suitable for China,and China should implement the system from nothing,from weak to strong when the national condition matches or strategic choice needs. Meanwhile,a mature registration approval system is the ba-sis of establishing data protection system.

ObjectiveTo investigate the clinical features of patients with painless acute pancreatitis ( AP),and to improve the diagnosis accuracy of painless AP.MethodsThe clinical data of 12 patients with painless AP were retrospectively collected from January 2007 to January 2011.Results The mean age of patients with painless AP was 52 years old.Seven (58.3％) patients complained of abdominal distension and discomfort,4 (33.3％) patients complained of nausea and vomiting,abdominal tenderness occurred in 7(58.3％ ) patients.Serum levels of lipase and amylase was increased in 11 (91.7％) and 8 (66.7％)patients,respectively.The diagnostic accuracy of abdominal ultrasound and CT for AP was 58.3％ and 91.7％,respectively.Five (41.7％) patients were diagnosed to have AP upon admission,and 4 patients were misdiagnosed to have non-digestive diseases.There were 7 severe AP patients among the 12 painless AP patients,and the percentage was significantly higher than that in AP patients with pain (65/327,x2 =7.30,P ＜ 0.05).Painless AP patients needed longer hospital stay when compared with that of AP patients with pain [ ( 20.4 ± 9.1 ) d vs.( 12.9 ± 6.2) d,t =2.296,P ＜ 0.05 ) ].ConclusionsThe misdiagnosis rate of painless AP is high and patients with painless AP are in critical situation,and early measurement of serum levels of lipase and amylase,as well as CT scan is important for correct diagnosis.

Objective To separate and screen components with fibrinolytic enzyme activity from twelve Chinese herbal medicines. Methods The components were extracted with water and precipitated with salt, and they were tested by fibrinolytic protein plates method. The active components with fibrinolytic activity were separated and screened which were compared with urokinase. Results Eleven of the twelve extracts showed fibrinolytic activity, while Trichosanthes kirilowii got the biggest fibrinolytic zone after 36 hours, followed by Alisma plantago-aquatica and Leonurus japonicus, and the Radix Astagali got the smallest one. According to the concentration of the protein, the area of the fibrinolytic zone and the specific activity of the components, the extract from Angelica sinensis exhibited the best specific activity at level of 48.46U/mg. Conclusion The extracts from Chinese herbal medicines except Semen Persicae exhibit fibrinolytic enzyme activity which can dissolve the fibrin in different degrees.

Objective To investigate the antiproliferative effect of suramin on trabeculectomy in rabit.Design Experimental study. Participants 32 New Zealand albino rabbits.Methods 32 albino rabbits were randomly divided into four groups.Both eyes of rabbits were performed trabaculectomy and placed a piece of cotton with 0.3 mg/ml mitomycin C(MMC)for 2 minutes in standard control group,220 mg/ml suramin for 2 minutes in experimental groupⅠ,250 mg/ml suramin for 2 minutes in experimental groupⅡ.The examination of intraocular pressure was performed before surgery.The filtration bleb and intraocular pressure were observed at 3,7,15, 30 days after surgery.Some conjunctiral specimen was observed with histochemicall(HE staining)and immunohistochemicall(PCNA staining)methods.Main Outcome Measures Intraocular pressure(IOP),filtering bleb appearance,histopathological staining.Results The percentage of the functional blebs in empty control group and experimental groupⅠwas lower than in standard control group,and experimental groupⅡwas higher than in the other 3 groups at 30 days after surgery.Immunohistochemical staining showed the number difference of PCNA positive cell nuclear was no significant between experiment groupⅠand standard control group,but less than empty control group,and experiment groupⅡwas the least(P

Objective To explore the application of integrating 64-slice CT image with three-dimensional electroanatomic mapping(Carto-Merge) in guiding catheter ablation of atrial fibrillation(AF).Methods Fifteen patients with drug-refractory AF received catheter ablation of AF.64-slice CT scan was performee 1-3 days prior to the ablation procedures.Using a novel software package,the left atrium(LA)with PVs was segmented and extracted for image registration with a combination of landmark registration and surface registration.Results The integration of the CT image into the electroanatomic mapping system was performed successfully in all patients with an error of 2.11?0.82 mm.Thirty pairs of PVs were electrically isolated after circumferential rediogrequency pulmorary rein ablation.The mean procedure time was 170.51?38.47 minutes.Cardiac tamponade occurred in one patient.All the fifteen patients were free of AF recurrence after 3 months of follow up including the 2 cases of persistent AF who required antiarrhythmic drugs.No thromboembolic events or stenosis were observed.Conclusion Integration of 64-slice CT image into the CARTO system successfully performed in patients undergoing catheter ablation of AF and enhance the ablation success rate.

Objective To study the correlation of the level of high-sensitivity C-reactive protein (Hs-CRP) in the acute phase of ischemic stroke and progressive stroke. Methods 101 patients with acute ischemic stroke were collected. Serum Hs-CRP of all patients were measured at 24 hours after admission , the onset of 48 hours, the onset of 72 hours by latex enhanced immune turbidity method. According to their serum Hs-CRP lev-els, the patients were divided into the group of Hs-CRP sustained growth (n = 35) and the group of non Hs-CRP sustained growth (n = 66). The NIHSS scores were assessed on two groups of patients , Logistic regression analysis was made to screen the related factors of Hs-CRP increase and the possible risky factors for progressive ischemic stroke. Results There was a significant difference of serum Hs-CRP level between the two groups (P <0.001). The incidence of progressive stroke in the group of Hs-CRP sustained growth was significantly higher than that in the group of non Hs-CRP sustained growth (χ2 = 32.710, P < 0.001). Logistic regression analysis showed blood glucose , white blood cell count , triglyceride level and NIHSS scores at admission were associated with sustained growth of Hs-CRP and the factors that they included Hs-CRP sustained growth , admission NIHSS scores, diabetes mellitus and pulmonary infection were regarded as independent risk factors. Conclusion The sustained growth of Hs-CRP in the acute phase of ischemic stroke is an independent predictor of progressive stroke.
