OBJECTIVERadial corrective osteotomy is an established but challenging treatment for distal radial malunion. There is an ongoing discussion about whether an opening or closing-wedge osteotomy between should employed. The purpose of the present study was to retrospectively compare the clinical and radio graphic results between conventional opening-wedge osteotomy and closing-wedge technique.

METHODSFrom January 2004 and December 2012,42 patients with extra-articular distal radial malunion were managed with corrective osteotomy and were followed for a minimum of one year. Twenty-two patients (5 males and 17 females, ranging in age from 25 to 75 years old) were managed with radial opening-wedge osteotomy and implanting of interpositional bone graft or bone-graft substitute, and twenty patients (4 males and 16 females, ranging in age from 19 to 79 years) were managed with simultaneous radial closing-wedge and ulnar shortening osteotomy without bone graft. The selection of the surgical procedure was determined by the surgeon. Each patient was evaluated on the basis of objective radio graphic measurements, and functional outcomes were determined on the basis of clinical examinations, including range of wrist motion, grip strength, pain-rating score, Mayo wrist score, and Disabilities of the Arm, Shoulder and Hand (DASH) score.

RESULTSThe mean duration of follow-up was 36 months (ranged, 12 to 101 months) for the opening-wedge cohort and 28 months (ranged, 12 to 87 months) for the closing-wedge cohort. The two techniques were comparable in terms of complications. Post-operative volar tilt and ulnar variance were improved significantly in each cohort. The ulnar variance was more frequently restored to within defined criteria (22.5 to 0.5 mm) in the closing-wedge cohort than that in the opening-wedge cohort. The post-operative mean extension-flexion are of the wrist and Mayo wrist score were significantly better in the closing-wedge cohort. Differences in the pronation-supination arc, grip strength, pain-rating score, and DASH scores between these two cohorts were not significant.

CONCLUSIONThe closing wedge osteotomy technique is an effective reconstructive procedure for the treatment of extra-articular distal radial malunion. It is significantly better than the opening-wedge osteotomy technique in terms of the restoration of ulnar variance, the extension-flexion arc of wrist motion, and the Mayo wrist score.

Adenosine receptors (AR) play an important role in the regulation processes for body temperature and vigilance states. During our previous studies, we noticed that aminophylline (a non-selective, blood-brain-barrier penetrably AR antagonist) could attenuate the effects of YZG-330 [(2R,3S,4R,5R)-2-(hydroxymethyl-5-(6-(((R)-1-phenylpropyl)amino)-9H-purin-9-yl)tetrahydrofuran-3, 4-diol] on lowering the body temperature. Hereby, we focused ourselves on the character of thermal regulation effect of YZG-330 in mice and tried to specify the receptor subtype via giving typical adenosine receptor antagonists. The results showed that both of the magnitude and lasting time of the effect that YZG-330 played on decreasing body temperature are in a dose-dependent manner: within the next 3 hour after intragastric administration (ig) of 0.25, 1 or 4 mg . kg-1 YZG-330, the extreme values on body temperature decreasing were (1.2 ± 0.3) °C, (3.6 ± 0.4) °C (P<0.001) and (7.4±0.5) °C (P<0.001), separately; whereas the duration that body temperature below 34 °C were 0, (10±5) and (153±4) min, separately. Adenosine A1 receptor (A1R) antagonist (DPCPX) could effectively reverse YZG-330's effect on decreasing body temperature, with intraperitoneal administration of DPCPX (5 mg . kg-1) 20 min prior than YZG-330 (4 mg.kg-1, ig), the extreme value on body temperature decreasing was (3.5 ± 0.7) °C (P<0.001), the duration that body temperature below 34 °C was (8±6) min (P<0.001). However, adenosine A2a receptor antagonist, SCH-58261, did not show any influence on the effects of YZG-330 at all. Combined with the fact that 8-SPT (a non-selective, blood-brain-barrier impenetrably AR antagonist) did not reverse the effect of YZG-330, we come to the conclusion that central-adenosine A, receptor plays a significant role on the thermal regulation effect of YZG-330.

Objective To explore influence of long-term inhaled glucocoticoids(IGS) on soluble intercellular adhesion molecule-1(sICAM-1)) in children with bronchial asthma.Methods Enzyme-linked immunosorbent assay(ELISA) method was used to detect the serum sICAM-1 level in 36 healthy children and 29 children with bronchial asthma(untreated and post-treated for 3,6 and 12 months).Results 1.Serum sICAM-1 level was significantly elevated in children with asthma and significantly higher than that in normal control group(P

Objective To explore the diagnostic value of multi-slice spiral CT with big field of view,thin slice thickness,and postprocessing in endobronchial tuberculosis Methods Ninety-eight clinically diagnosed and tuberculosis bacillus positive patients were included The multi-slice spiral CT was performed using 3 mm thickness scan,MiIP,CVR,and CTVE management The CT diagnosis was made by the single-blind method and was compared with fiberoptic bronchoscope and pathology Results Main CT features were as follows: obstruction of bronchia in 13 cases (9 6%),uniform stricture of bronchia in 27 cases (19 8%),and non-uniform stricture of bronchia in 96 cases (70 6%) The lesions located in the main bronchia in 31 (22 8%),pulmonary lobar bronchia in 81 (59 6%),and pulmonary segmental bronchia in 24 (17 7%),respectively Multiple lesions were found in 56 cases (51 7%) The sensitivity,specificity,and accuracy of multi-slice spiral CT in the diagnosis of endobronchial tuberculosis were 89 8%,63 2%,and 84 6%,respectively Conclusion The exertion of multiple functions of multi-slice spiral CT can increase the diagnostic level for endobrochial tuberculosis,and spiral CT is a good supplementary to fiberoptic bronchoscope

Objective To investigate the clinical characteristics and risk factors of bacterial liver abscess (BLA) complicated with septicemia.Methods Fifty two BLA patients complicated with septicemia admitted in our hospital from January 2011 to December 2015 were retrospectively reviewed;and 52 cases of BLA without septicemia admitted at the same period were randomly selected as control group.The clinical manifestations, laboratory and radiographic findings, clinical outcome of these patients were analyzed.Logistic regression analysis was used to study the clinical features and risk factors of BLA complicated with septicemia.Results Compared to the control group, the BLA with septicemia group had higher prevalence rates in diabetes mellitus, malignant tumors, jaundice, albumin <35 g/L, BUN≥8.2 mmol/L, hyperglycemia, multiple abscesses and abscesses size ≥10 cm(P<0.05 or <0.01).The blood culture showed that K.pneumoniae(63.3%) was the most commonly isolated pathogen, followed by E.coli(16.7%).Univariate analysis revealed that diabetes mellitus(OR=2.200,95%CI 1.042-4.646), malignant tumors (OR=3.667,95%CI 1.023-13.143), albumin <35 g/ L(OR=2.800,95%CI 1.009-7.774), BUN≥8.2 mmol/L(OR=3.167,95%CI 1.265-7.929), hyperglycemia(OR=3.400,95%CI 1.254-9.216), multiple abscesses(OR=2.667,95%CI 1.043-6.815), abscesses size≥10 cm (OR=5.000,95%CI 1.096-22.820) were positively associated with bacterial liver abscess complicated with septicemia.Multivariate Logistic regression showed that abscesses size≥10 cm (OR=14.016,95%CI 1.354-145.070) was an independent risk factor for complication of with septicemia.Conclusion septicemia is a common complication for bacterial liver abscess, clinically effective measures shauld be taken to prevent and control risk factors associated with septicemia.
