OBJECTIVE:To analyze the characteristics and rules of pediatric adverse drug reaction (ADR) in our hospital, and provide reference for clinical safe drug use. METHODS:Retrospective study was adopted to statistically analyze the ADR re-ports in our hospital from Mar. 2012 to Jun. 2016. RESULTS:In the 176 ADR reports,102 were male(57.95%)and 74 were fe-male (42.05%);children younger than 6 years old had the highest incidence of ADR (81.26%);intravenous administration in-duced 153 cases(86.93%),the top one was antibiotics,which involving 20 antibiotics,totally 106 cases(60.23%);skin and its appendages damage were the main manifestations, totally 127 cases (50.60%). CONCLUSIONS:Pediatric ADR monitoring should be strengthened,dinical rational drug use should be promoted by cooperation in many ways to reduce and prevent the incid-erle of pediatric ADR.

This report emphasizes on US diagnostic characteristics of partly BSTT,including OSteogenic sarcotma in 57 cases,chondrosarcoma in 25 cases, fibrosarcoma in 18 cases, synovial sarcoma in 14 cases, myelogenous neoplasm in 21 cases.metastatic bone ttmlor in 67 cases,giant cell turnor of bone in 52 cases, chordoma in 25 cases,hemangioma In 32 cases,desmoplastic fibroma in 10 cases. Pigrnenled villonodular synovius in 10 cases,and aneurysmal bone cyst in 8 cases, altogether 563 cases. The study firstly presents the application and specific menifestation of US diagnosis in BSTI. In many aspects,US is superor to X-ray, CT and MRI in diagnosing BSTT. It provides a great deal of reliable basis for clinical diagnosis and. Treatment.

Colorectal cancer is a very common malignant neoplasm.It is widely accepted that community screening for colorectal cancer significantly reduces mortality of this disease.Detection of neoplasm is facilitated by fecal occult blood testing(FOBT),sigmoidoscopy,colonoscopy and double contrast barium enema.Colonoscopy is currently the gold standard,however,the appropriate age to begin testing and time interval between repeat sereenings remain unclear.Screening with CT colonography(vivtul colonoscopy),fecal DNA analysis and detecting cyclooxygenase 2 messenger RNA in feces is under study.Finding the optimal screening method and increasing acceptability to both physician and patients remain to be studied further.

The growth hormone(GH)-insulin-like growth factor(IGF)-I axis is an important modulator of growth and development.In addition to the classical role as endocrine hormones,the components also regulate a wide range of biological functions through paracrine and autocrine mechanisms.Their potent mitogenic and anti-apoptotic effects play a critical role in the regulation of rapidly renewing epithelial cell populations such as those found in the colon.Recent epidemiological evidence from acromegaly patients suggests an association between inappropriate regulation of the GH-IGF-I axis and the development of colorectal cancer.However,the molecular mechanisms and signalling pathways responsible are only beginning to be unravelled,as are the relative contributions of the endocrine and autocrine or paracrine effects.

Deconstruction of lignocellulosic plant cell walls to fermentable sugars by biochemical means is impeded by several poorly understood ultrastructural and chemical barriers. Pretreatment is an essential step by altering the morphological and compositional characteristics of biomass to enhance the sugar release during enzymatic hydrolysis. Therefore, getting insight into this field is necessary to improve the conversion of biomass into biofuels. In this review, we highlight our recent understanding on the impact of various promising pretreatments on biomass, with emphasis on the topochemical and ultrastructural changes of plant cell walls that are related to the reduction of recalcitrance and the consequence of saccharification. It will lend support to the scientific research and development with respect to biomass conversion.

Objective To investigate the influence rule of the atmospheric Rainfall to the γ radiation Kerma rate in surface air in order to revise the resuh of its measurement during rainfall.Methods The influence factors of rainfall to the measurement of the γ radiation Kerma rate in air were analyzed and then the differential equation of the correlation factors was established theoretically,and by resolving the equation,the mathematical model Was obtained.The model was discussed through several practical examples.Results The mathematical model was coincided with the tendency of curve about the measured data on the influence rule of rainfall to the γ radiation Kerma rate in surface air.Conclusion By using the theoretical formula in this article which is established to explain the relationship between the rainfall and the γ radiation Kerma rate in surface air,the influence of rainfall to the γ radiation Kerma rate in surface air could be correctly revised.

Objective To evaluate economic benefits and clinical effects of internal fixation treatment of severe rib fracture so as to provide objective basis for improving medical treatment for rib fracture.Methods A retrospective review was made on clinical data of 50 patients with severe rib fracture hospitalized from January 2009 to April 2014.With varied treatment modalities,the patients were assigned to operative group (n =13) and non-operative group (n =37).Variables were recorded including length of stay,total hospital charges,length of ventilatory support,off-bed time,duration of antibiotic use and incidence of complications and used to perform cost-efficiency analysis.Results Between operative and non-operative groups,length of hospital stay was (25.9 ± 8.2) days vs (35.4 ± 7.0) days,total hospital charges were (121 676.2 ± 10 991.1) yuan vs (148 724.5 ± 21 254.3) yuan,length of ventilatory support was (7.9 ± 2.8) days vs (14.1 ± 3.3) days,off-bed time was (14.3 ± 4.9) days vs (26.1 ± 6.5) days,duration of antibiotic use was (12.4 ± 3.3) days vs (21.2 ± 6.2) days and complications occurred in 2 cases vs 13 cases respectively.The findings were length of ventilatory support,off-bed time and duration of antibiotic use differed significantly between the two groups (P ＜ 0.05).Cost-effectiveness ratios based on subjective and objective measures were superior in operative group (1 962.52 and 3 925.03) over those in non-operative group (1 931.48 and 3 718.10),suggesting operative treatment could yield higher economic returns.Conclusion Internal fixation can accelerate bone healing in patients with severer rib fracture and cut down medical expense,which should be promoted in medical treatment.

·AIM: To study the therapeutic effect of surgical treatment for traumatic cataract.·METHODS: Seventy-three cases(73 eyes) traumatic cataract were performed multi-operation combined cataract extraction, including insertion of a capsular tension ring(CTR), vitreoretinal surgery, ocular foreign body extraction and intraocular lens(IOL) implantation.·RESULTS: Of 73 patients, twenty-seven cases were blunt trauma, while 46 cases were penetrating injuries. Three months after surgery, the final best spectacle-corrected visual acuity(BSCVA) in 5 patients (7%) were 0.05 or less, seventeen(23%) 0.05 to 0.3, while 49(67%) 0.3 or more. There were 93% cases relieved from blindness. Atrophy of eyeball occurred in two cases(3%). Mean follow-up time was 7.8(range 3-15) months.·CONCLUSION: Useful vision can be restored in a proportion of traumatic cataracts after prompt and rational surgical intervention as well as appropriate treatment of sight-threaten complications.

The angiogenesis inhibitor endostatin is a 20 000 C terminal fragment of collagen ⅩⅧ.Endostatin inhibits endothelial cell migration in vitro and appears to be highly effective in murine in vivo studies. Endostatin is a specific and the most effective antiangiogenisis till now. The molecular mechanisms behind the inhibition of angiogenesis have not yet been elucidated.The structure and functional roles in angiogenesis of wllagen ⅩⅧ/endostatin were reviewed.
