Objective To review the effect of exposed and buried Kirschner wire fixation of lateral humeral condyle fracture in children.Methods Randomized control trials (RCTs) about exposed versus buried Kirschner wire fixation of lateral humeral condyle fracture in children were identified through electronic search using the Cochrane Collaboration search strategies and manual search.Electronic database included Cochrane Library,Medline,PubMed,CBM,VIP,CNKI,Wanfang database and other Chinese and English database.Manual research included related journals and conference proceedings.Quality analysis of the included literatures was performed using the methodological index for non-randomized studies (MINORS).RevMan 5.3 software was used for Meta analysis.Results Four studies involving exposed Kirschner in 150 cases and buried Kirschner in 351 cases were included.The two techniques were similar with respect to postoperative infection (OR =1.10,95％ CI 0.52 ～ 2.33,P ＞ 0.05),superficial infection (OR =1.45,95 ％ CI 0.66 ～ 3.18,P ＞ 0.05),reoperation rate (OR =2.29,95％CI 0.51 ～ 10.25,P ＞0.05),delayed union rate (OR =1.57,95％ CI 0.76 ～ 3.21,P ＞0.05) and total complications (OR =1.57,95％ CI 0.76 ～ 3.21,P ＞ 0.05).However,Kirschner wire exposure shortened the time of pulling out Kirschner wire (MD =-13.28,95％ CI-16.42 ～-10.14,P ＜0.05).Conclusion Applied for lateral humeral condyle fracture in children,exposed versus buried Kirschner wire fixation results in short Kirschner wire stabilization time that avoids local anesthetic and cost while pulling out Kirschner wire in the late stage.

A new vest pocket medical instrument is here presented. It can automatically detect and identify the signals of the onset of epileptic seizures, and then as necessasy, will automatically generate an acoustic stimulation that may weaken and shorten the epileptic activity at the initial stage.

Objective To observe the protective effect of N-NAC on radiation-induced lung injury. Methods 86 cases of thoracic neoplasm patients were chosen and randomly divided into two groups,group RT +N(n =43)and group RT(n =43).Two groups were observed by CT after radiotherapy.Acute and chronical toxicities were graded by RTOG.TGF-β1,IL-1,IL-4,TNF were observed before and after the radiotherapy.Results After 3 monthsof radiotherapy,RTOG≥2 was 23.4%(RT +N),while RTOG≥2 was 53.1%(RT).there was significant differencebetween the two groups(P <0.01).At 6,9 and 12 months,fibrosis was present in 28.4%,25.4%,22.4% receivingRT vs 58.4%,54.4%,52.4% receiving RT +N,there was significant difference between the two groups(P <0.05).TGF-β1,IL-1,IL-4,TNF were observed which showed that The RT +N were lower than RT.Conclusion N-NAC can reduce incidence rate of lung injury in radiotherapy,and can reduce the content and the release of TGF-β1,IL-1,IL-4,TNF.

This study aims to explore the impact on patient's liver and kidney function by different dosage of Kudiezi injection. This study retrospectively analyzed 15 228 patients' records from 18 nationwide general hospital information system (HIS). All patients were treated with Kudiezi injection, 1 956 patients that were given doses of > 40 mL, which is above the recommended dose, acted as the observation group. Fifty-five patients receiving the recommended dose of < 40 mL were the control group. Data about alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine (Cr) and blood urea nitrogen (BUN) were collected before and after using Kudiezi injection, changes after treatment were outcomes. Also recorded were: age, costs, length of hospitalization and the patients' condition on admission. Propensity score method was used to balance 71 confounding variables such as gender, age, mortality, and costs. There were no significant difference on the four indexes between the two groups. It is hard to conclude that the use of Kudiezi injection over the recommended dose could influence the four indexes of liver and kidney from this data analysis. More conclusive evidence should be collected by further prospective study.

Objective To analyze the pathological and clinical characteristics of patients with idiopathic IgA nephropathy accompanied by vasculitic/crescentic lesion (IgA-V/C). Methods Data of 222 patients diagnosed as idiopathic IgA nephropathy by renal biopsy, among them 87 cases with vasculitic/crescenlic (V/C)lesion, from our department in 2004 were analyzed retrospectively. Clinical and pathological data from patients with IgA-V/C were compared to those of non-IgA-V/C patients and of lupus nephritis (LN) patients with V/C lesion. Results Vasculitic/crescentic lesion was found in 39.19% (87/222) patients with idiopathic IgA nephropathy.And about( 14.08?12.75)% of the glomeruli was affected. It should be taken into account that there was no significant differences of clinical manifestations including blood pressure, urinary protein excretion between IgA-V/C group and non-IgA-V/C group .except serum creatinine(Scr)level which was significantly higher in IgA-V/C group. In addition, only 37.9% of IgA-V/C patients presented high Scr level,thus the lesion of V/C in idiopathic IgA nephropathy was easily overlooked. Patients with idiopathic IgA nephropathy were found to have higher percentage of glomerular sclerosis (64.86% vs 40.00%) and ratio of sclerostic glomeruli to total glomeruli [ (26.98 ?24.68)% vs (16.10 ?18.80)% ]as compared to LN group, which further predicated the progressing characteristics of IgA nephropathy. Conclusions Vasculitic/crescentic lesion is a quite common finding in idiopathic IgA nephropathy and often associated with no dramatically symptoms. It is possible for vasculitic/crescentic lesion to induce unmarked lose of nephron slowly and continually, so as to accelerate IgA nephropathy progression to end-stage renal failure.

ObjectiveTo explore the effect of estrogen on osteoblast apoptosis induced by serum hungry in vitro.MethodsOsteoblasts of second or third generation from newly born SD rats calvaria were divided randomly into the control group, serum hungry group and serum hungry with estrogen group. Cells of each group were incubated for 24 h, 48 h, 72 h, 5 d, 7 d and 14 d, then labeled using TUNEL staining and examined for morphological characteristics of apoptotic cell under light microscopy after incubated for 72 h. The rates of apoptotic cells of each group were examined with flow cytometry.ResultsThe cells of the control group showed normal appears, the serum hungry group had many cells with purple and blue particles in nuclei, but serum hungry with estrogen group had less such cells. The rate of apoptotic cell significantly increased in serum hungry group and decreased in serum hungry with estrogen group compared with the control group examined with flow cytometry (P<0.05).ConclusionEstrogen can repress osteoblasts apoptosis of rats induced by serum hungry.

OBJECTIVETo create an integrated digital maxillodental model and to apply it in computer aided design (CAD) of individualized lingual brackets in order to align both crowns and roots without fenestration and dehiscence.

METHODSCone-beam computerized tomography (CBCT)-based maxillodental model and laser-scanned dental model were integrated by auto registration in 10 patients with malocclusions. The registration error was calculated automatically. Three observers tested the method independently. The inter-observer difference was investigated. An integrated model was selected randomly and the setup was created with roots and jaws in good relationship without fenestration and dehiscence. The individualized lingual brackets were designed by CAD on the setup.

RESULTSNo significant difference was found in inter observers (P > 0.05). The registration errors of maxilla and mandible were (0.144 ± 0.020) mm and (0.141 ± 0.022) mm, respectively. The digital individualized lingual brackets based on the virtual treatment in integrated digital maxillodental model were produced.

CONCLUSIONSAn integrated digital maxillodental model was created in good accuracy. By applying the integrated model, individualized lingual brackets were designed.

OBJECTIVETo study the effect of endophytic fungi.

METHODA. formosanus, harvested after having been cultured for age, statistics were taken, fresh weight and dry weight were gained, and enzyme activities of chitinase, beta-1,3-glucase, phenylalanine ammonia-lyase and polyphenoloxidase were determined.

RESULTThe survial rates of A. formosanus inoculated with endophytic fungi was 100%. The effect of fungi on fresh weight was very significant (P < 0.01). The effect of fungi on dry weight was significant (P > 0.05). The four enzyme activities were enhanced by endophytic fungi, comparision with the controls.

CONCLUSIONSurvial rates of A. formosanus can be increased by using endophytic fungi in vitro culture.
