Objective To observe the curative effect of low melocular weight heparin(LMWH) on the hypercoagulability in acute Kawasaki disease(KD).Methods Forty-six patients were diagnosed KD.Twenty-two cases out of all KD patients whose serum concentration of whether platelet(PLT) or fibrinogen(FIB) was significantly increased or who were found thrombus in their coronary artery by ultrasonic Doppler were treated with LMWH by subcutaneous injection once every day for 7-10 days.All the patients were divided into 2 groups accor-ding to whether using LMWH or not:H group(using LMWH) and NH group(no using LMWH).It were detected before and after treatment that included thrombin time(TT),activated partial thromboplastin time(APTT),international normalized ratio(INR),FIB,plasma mucosity,erythrocyte sedimentation rate(ESR),hematocrit(HCT) and situation of haemorrhage.Results 1.Before treatment,PLT and FIB of patients in H group were significantly higher than those in NH group(Pa

OBJECTIVETo study the surgical management of enophthalmos after severe malar maxillary complex fracture.

METHODSThe X-ray and CT examination were performed before operation to diagnose the orbital fracture and intraorbital tissue displacement. The fractured orbital rim was repositioned intraoperatively, followed by implantation of shaped titanium mesh to rebuild the orbital floor. The Medpor was inserted above the titanium mesh to correct the enophthalmos.

RESULTSFrom Sept. 2007 to Jan. 2009, 6 cases of enophthalmos after severe malar-maxillary complex fracture were treated. The enophthalmos was corrected or improved obviously in all the patients.

CONCLUSIONSThe enophthalmos after severe malar-maxillary complex fracture can be corrected or obviously improved. Shaped titanium mesh can be used to rebuild the orbital floor with the Medpor to reconstruct the intraorbital tissue volume.

Objective To review the diagnosis and treatment of epithelioid angiomyolipoma of the kidney. Methods Five cases of epithelioid angiomyolipoma of the kidney were retrospectively analyzed in the aspects of imaging and pathologic characteristics. There were 3 males and 2 females with average age of 46 years (ranging from 26-64 years). There were 3 patients complained of pains of lumber. Two cases were found renal masses in routine physical examination. The mass diameter was 2.9-10. 1 cm. Two cases were diagnosed as angiomyolipoma and three as malignant tumors as kidney cancer, tumor of the adrenal gland or tumor of the liver with ultrasound and CT scan. Four of the 5cases accepted partial nephrectomy and 1 with radical nephrectomy. Results Epithelioid angiomyolipoma of the kidney was composed of abnormal thick parietal vessel, smooth muscle and adipose tissue in different proportional. The cytoplasm of epithelioid cells was acidophilia or lucency, which had acidophilia particles and abundant blood vessels. Epithelioid cells were round or polygon, surrounded to blood vessels, distributed in lipoid. The SMA, Vimentin and HMB45 were positive by immunohistochemisty. The post-operative histological diagnosis showed that all cases were epithelioid angiomyolipoma of the kidney. All patients were followed up for 2 to 12 months. No patients had locally recurrence or distant metastasis. Conclusions The diagnosis of epithelioid angiomyolipoma of the kidney relies on histopathology results. The immunohistochemical staining could be helpful for diagnosis and differential diagnosis.

Objective To investigate the utility of diffusion weighted imaging (DWI) and blood oxygen level-dependent (BOLD) magnetic resonance imaging (MRI) in the assessment of renal hypoxia in an experimental model of mice with lupus nephritis (LN).Methods MRL/lpr mice (n=13) were studied and C57BL/6 mice (n=10) served as controls.Urinary albumin to creatinine ratio (ACR),serum creatinine (Scr),anti-ds-DNA antibody,and complement C3 levels were measured.The mice underwent coronal echo-planar DWI and BOLD MRI of the kidneys when they were 14-16 weeks old.Hypoxyprobe was administered intraperitoneally to the mice 1 hour before they were sacrificed.The distribution of HypoxyprobeTM-1,hypoxia-inducible factor 1 α (HIF-1 o) and heme oxygenase-1 (HO-1) in renal tissues was detected by immunohistochemical analysis and Western blotting.Results Urinary ACR,Scr and anti-ds-DNA antibody levels in MRL/lpr mice were significantly higher than that in C57BL/6 mice.It was found that HypoxyprobeTM-1,HIF-1o and HO-1 distributed widely in the renal tissue of MRL/lpr mice,and closely associated with the renal tubulointerstitial lesion.The mean apparent diffusion coefficient (ADC) value of kidneys in MRL/lpr mice was (1.52±0.27) × 10-3 mm2/s,and the mean R2* values of the renal cortex and medulla were (30.95 ±4.59)/s and (23.43± 3.06)/s respectively,all significantly lower than that in C57BL/6 mice (P=0.037,P=0.030 and P=0.043,respectively).The ADC of medulla was negatively correlated with urinary albumin to creatinine ratio (r=-0.364,P=0.032;r=-0.329,P=0.050),the ADC of cortex was negatively correlated with the level of serum creatinine (r=-0.814,P=0.014;r=-0.755,P=0.031) when b value was 500 s/mm2 and 800 s/mm2,and the mean R2* value was negatively correlated with the degree of tubulointerstitial lesions and the expression of hypoxia parameters (all P ＜ 0.05).Conclusions Renal hypoxia may play an important role in renal tubulointerstitial lesion.Functional MRI may be used to monitor renal function changes,pathological injuries and renal hypoxia in LN.

Objective To evaluate the effect of rehabilitation training on rats with spinal cord injuries by Meta-analysis. Methods Ar-ticles were searched from PubMed( ~2013),CNKI(1989~2013), WanFang Data( ~2013),VIP(1989~2013),quality of included article was assessed with Jadad scale,and available data was analyzed with RevMan 5. 0 software. Results 287 related articles were identified,but only 11 eligible articles were included. The Meta-analysis of BBB score indicated that the rehabilitation training groups were better than con-trol groups. The BBB score[weighted mean difference(WMD) =1. 87,95%CI(1. 50,2. 33),Z=10. 02,P<0. 01]. There was significant diffence between two groups. Conclusion Rehabilitation training can improve the recover of hindlimb function.

Objective: To understand the prevalence of hepatitis C virus ( HCV ) infection in sentinel surveillance in Liaoning Province from 2015 to 2019, in order to provide evidence for the precise prevention and control of HCV. Methods: The HCV sentinel surveillance data of 5 kinds of populations, including dialyzed patients, patients receiving invasive diagnosis and treatment, family planning outpatients, people receiving physical examination and unpaid blood donators in Liaoning Province from 2015 to 2019 were retrieved, and the HCV positive rates of different years, gender and age groups in the five populations were analyzed. Results: There were 26 000 persons surveyed and 61 HCV positive cases were detected from 2015 to 2019. The HCV positive rate was 0.23%. The HCV positive rates of dialyzed patients, patients receiving invasive diagnosis and treatment, family planning outpatients, people receiving physical examination and unpaid blood donators were 0.40%, 0.70%, 0.25%, 0.24% and 0.14%, respectively. The HCV positive rates of dialyzed patients, patients receiving invasive diagnosis and treatment, and unpaid blood donators had significant downward trends ( P<0.05 ). The HCV positive rates of males and females were 0.22% and 0.26%, without any significant difference ( P>0.05 ). The HCV positive rate of people aged above 70 years old was 1.15%, the highest among different age groups. Conclusions The prevalence of HCV infection among the patients with hemodialysis and with invasive diagnosis and treatment is relatively high. The level of HCV antibody of older age groups should be monitored regularly.
