ABSTRACT
Objective To evaluate K-wire leverage reduction and fixation via the triceps tendon for irreducible supracondylar humeral fractures of Gartland types Ⅱ& Ⅲ. Methods From June 2014 to March 2016, 31 children with irreducible supracondylar humeral fracture were treated operatively in our hospital. They were 23 boys and 8 girls, aged from 4 to 11 years ( average, 6. 3 years ) , involving 19 left and 12 right arms. Their clinical manifestations included elbow swelling at the affected arm, obvious tenderness, and limited movement of the elbow. The reduction was conducted under the guidance of C-arm roentgenography by inserting a piece of 3. 0 mm K-wire into the fracture ends via the posterior triceps tendon, inserting 2 pieces of 1. 5 or 2. 0 mm K-wire from the distal lateral humerus to the proximal through the opposite cortical bone, and inserting a piece of 1. 5 or 2. 0 mm K-wire into the opposite cortical bone through the ulnar aspect of the distal humerus. Results The operation time for the 31 patients ranged from 28 to 42 minutes ( 33 minutes on average ) . They were followed up for 6 to 18 months ( 12. 3 months on average ) . All fractures united after 4 to 6 weeks ( 4. 6 weeks on average ) . At the final follow-ups, the lengths of the affected and healthy arms were re-spectively 66. 4 ± 2. 7 cm and 66. 4 ± 2. 9 cm, showing no significant difference ( P> 0. 05 ) . The therapeutic outcomes by the Flynn criteria for the elbow function were rated at the final follow-up as excellent in 26 cases, as good in 4 and as fair in one, yielding an excellent to good rate of 96. 8％. Pin tract infection occurred in 2 patients, but no deep infection or osteomyelitis was observed during follow-ups. Conclusion K-wire leverage reduction and fixation via the triceps is an effective and simple treatment for irreducible supracondylar humeral fractures of Gartland types Ⅱ& Ⅲ.
ABSTRACT
Objective To explore the prevalence of the nuclear dense fine speckled ( DFS ) immunofluorescence pattern in routine antinuclear antibodies(ANA) testing and its significance in patients with autoimmune diseases( AID) .Methods The ANA in 13 728 specimens were measured by indirect immunofluorescence( IIF) using HEp-2 cell slides from department of clinical laboratory, wenling hospital from 2011 to 2014.The frequencies, clinical manifestations and laboratory features of DFS positivity were restrospectively analyzed in patients with AID,usingχ2 test.Results ANA was positive in 20.56%(2 822/13 728) of the total patients, and the frequency of DFS pattern was observed in 1.81%(248/13 728) of the total patients and in 8.79%(248/2 822) of the patients with ANA positivity.In different age groups (≤20 years old, 21-49 years old and≥50 years old) , there were statistical significance of DFS pattern positive rate (male:χ2 =18.17,P<0.01; female: χ2 =1 500.00,P<0.01).And the highest frequency of ANA positivity was observed in patients from department of rheumatology(30.07%).The frequency of DFS pattern was higher in the departments of infection ( 32.58%) , dermatology ( 21.76%) , neurology ( 18.58%) and nephrology(6.73%) among the patients with ANA positivity(χ2 =123.00,P<0.01).Amony the 248 cases with DFS pattern positivity.41 cases were AID ( 16.53%) and 207 cases were non-autoimmune diseases ( 83.47%) . In AID group 13 cases were autoimmune thyroiditis ( 31.71%) , 12 cases were rheumatoid arthritis ( 29.27%) , 4 cases were autoimmune liver disease ( 9.76%) , 4 cases were undifferentiated connective tissue disease (9.76%), 3 cases were ankylosing spondylitis(7.32%), 2 cases were Sj?gren′s disease ( 4.88%) , 2 cases were inflammatory bowel disease ( 4.88%) and 1 case was systemic lupus erythematosus(2.44%).The titers of DFS in patients with AID were predominantly above 1∶320 and less than 1∶100 in non-AID.AID patients with DFS pattern positivity have different clinical manifestations and laboratory features.Howerer, antinuclear antibodies ( ANAs ) in 15 specific auto-antibodies were all negative.Conclusions The DFS pattern is a common pattern in ANA positivity patients and it mainly exists in non-AID patients.Further more, it is suggested that patients with DFS pattern identified by IIF should then be tested for anti-DFS70 antibodies with a specific immunoassay.
ABSTRACT
Objective:To explore the effect of lipoic acid on oxidative stress,inflammation and nutritional status in peritoneal dialysis patients.Methods:94 peritoneal dialysis patients were randomly divided into the observe group(n=47) the control group(n=47).They all accepted the conventional treatment,but the patients in the observed group were given the treatment of lipoic acid capsules(0.2 g tid) for 12 weeks.Superoxide dismutase(SOD),malondialdehyde(MDA),serum advanced oxidation protein products ( AOPPs ) were used to reflect the level of oxidative stress, high sensitive CRP, IL-6 and TNF-αwere used to reflect the micro inflammatory state, modified quantitative subjective global assessment ( MQSGA ) , mid-arm circumference, mid-arm muscle circumference,triceps skinfold thickness ( TSF ) , body mass index ( BMI ) , and serum albumin were used to reflect the nutritional status.The difference of oxidative stress, micro inflammatory state and nutritional status were compared between the two groups.Results:①In the observation group,the concentrations of AOPPs and MDA after treatment were significantly lower than that before treatment,and the concentration of SOD after treatment was significantly higher than that before treatment ( P<0.05 );after treatment,the concentrations of AOPPs and MDA in the observe group were significantly lower than that in the control group(P<0.05), and the concentration of SOD in the observe group was significantly higher than that in the control group ( P<0.05 ) .②In the observation group,the concentrations of high sensitive CRP,IL-6 and TNF-αafter treatment were significantly lower than that before treatment(P<0.05);after treatment,the concentrations of high sensitive CRP,IL-6 and TNF-αin the observe group were significantly lower than that in the control group ( P<0.05 ) .③In the observation group, the TSF, mid-arm circumference, mid-arm muscle circumference,BMI and albumin after treatment were significantly higher than that before treatment(P<0.05),and the MQSGA after treatment was significantly lower than that before treatment ( P<0.05 );after treatment, the MQSGA in the observe group was significantly lower than that in the control group(P<0.05),and serum albumin in the observe group was significantly higher than that in the control group(P<0.05).Conclusion:Lipoic acid could improve oxidative stress in peritoneal dialysis patients,so as to improve the micro inflammatory state and nutritional status.

ABSTRACT
Objective To investigate the impact and the associated parameters of malnutrition and inflammation status on hospitalization and mortality of maintenance hemodialysis (MHD) patients. Method A total of 118 MHD patients were included in the study with 1 year's follow-up.The malnutrition and inflammation parameters were compared between the hospitalized patients and out-patients.Cox's proportional hazard regression model was used to explore the malnutrition and inflammation parameters which could forecast the risk of hospitalization and mortality. Result The hospitalization rate of MHD patients with mild,moderate and severe malnuttition was 32.93％,56.67％ and 83.33％ respectively,and the mortality was 3.66％,6.67％ and 80.00％ respectively.The hospitalization rate of MHD patients with or without microinflammation status was 56.45％ and 46.43％,and the mortality was 14.29％ and 1.61％.Inpatients had a higher malnutrition-inflammation score(MIS,8.36 vs 5.86,P＜0.05) and subjective global assessment of nutrition (MQSGA,14.49 vs 12.88,P＜0.05),a lower creatinine level (886.83 μmol/L vs 991.76 μmol/L,P＜0.05 ) and a lower albumin level (38.57 g/L vs 40.27 g/L,P＜0.05) than out-patients.Inpatients also had a higher level of TNF-α (65.41 μg/L vs 59.76 μg/L,P＜0.05) than out-patients.Cox proportional hazard model analysis showed that MIS and TNF-α were associated with patient's first hospitalization risk. Conclusions For the MHD patients,the more severe the malnutrition and micro-inflammation status is,the worse the clinical outcome is.The higher levels of MIS and TNF-α result in greater risk of hospitalization.
