OBJECTIVETo evaluate cost-effectiveness of poking reduction and open reduction for the treatment of Sanders type II calcaneal fractures, in order to provide evidence for standard treatment.

METHODSFrom 2006.10 to 2008.10, 80 patients with Sanders type II calcaneal fractures were selected from Shandong Provincial Hospital of Traditional Chinese Medicine and randomly divided into poking reduction group and open reduction group with 40 cases in each group. There were 26 males and 14 females in poking reduction group and 30 males and 10 females in open reduction group. The average age of patients in poking reduction group was (36.60+/-3.15) years, and (37.10+/-3.45) years in open reduction group. Bohler angle, Gissane angle, the width of central calcaneus, stance phase of gait, HM-HL,arch index and subtalair joint flexibility were measured. The clinical results and expenses of the two treatment schemes were compared and concluded with the method of cost-effetiveness analysis.

RESULTSIn the poking reduction group and open reduction group, the Böhler angle were (30.32+/-1.72) degree and (30.54+/-3.13) degree, Gissane angle were (133.73+/-6.73) degree and (134.86+/-4.90) degree, the width of central calcaneus were (30.18+/-1.59) mm and (30.24+/-1.25) mm, stance phase of gait were (0.679+/-0.070) s and (0.715+/-0.090) s, HM-HL were--(36.49+/-7.56) N and -(34.32+/-6.50) N,arch index were (30.26+/-2.69) and (30.47+/-1.89), and subtalair joint flexibility were (10.53+/-2.30) degree and (10.89+/-1.86) degree respectively. The cost-effectiveness ratio (C/E) were 6.06 and 136.19 respectively.

CONCLUSIONCost-effectiveness ratio of the poking reduction is superior to that of the open reduction in treating Sanders type II calcaneal fractures. Poking reduction is a useful method to treat Sanders type II calcaneal fractures with rapid wound healing and less cost.

Objective: To understand the prevalence and associated factors of functional constipation(FC) among primary and middle school students in Shaanxi Province, in order to provide a basis for preventing FC in students. Methods: A stratified cluster random sampling method was used to conduct a questionnaire survey on 9 133 primary and middle school students aged 10-18 in eight primary and secondary schools in Shaanxi Province from March to September,2017. Chi square test and multivariate Logistic regression were used to analyze the associated factors of FC among primary and middle school students in Shaanxi Province. Results: There were a total of 364 students meeting the FC Rome IV diagnostic criteria, with a prevalence rate of 3.99%. Among them, there were 155 male students with a prevalence rate of 3.43%, and 209 female students with a prevalence rate of 4.53%. Univariate analysis showed that gender, breastfeeding, separation from parents, long term school meals, types of staple foods, breakfast frequency, cold foods eating frequency, spicy foods eating frequency, fried food eating frequency, pickled food eating frequency, desserts eating frequency, vegetables eating frequency were related to FC, and the differences were statistically significant ( χ 2=7.30,18.75, 20.89,35.54,22.43,16.05,21.31,13.97,10.33,23.96,16.25,17.74, P <0.05). Multivariate Logistic regression analysis showed that female, non breastfeeding, separation from parents, long term school meals, low consumption of staple food/staple food dominated by rice, and never eating vegetables were positively correlated with FC( OR =1.37,1.96,1.52,2.07,1.76,1.58,2.31, P < 0.05 ). Conclusions The prevalence of functional constipation is higher in primary and middle school students. Attention should be paid to factors related to students dietary habits and food classification to prevent the occurrence of FC in primary and middle school students.

[Summary] Four patients with hyperthyroid-associated exophthalmos, myxedema, acropachy ( EMA ) syndrome, including three male patients and one female patient were diagnosed with Graves′diseases and treated by 131 I therapy. Complaints of thyrotoxicosis were presented at the onset. Tibia myxedema and acropathy appeared, and eye symptoms aggravated in two patients after anti-thyroid drug therapy and 131 I therapy. Four cases were all given clobetasol propionate, miconazole nitrate, neomycin sulfate and urea cream alone or in combination with compound betamethasone local injection treatment, and three cases were given low-dose oral prednisone treatment. Complaints of tibia myxedema and eye symptoms were significantly improved after the treatment. Therefore, we should be wary of the occurrence of hyperthyroid-associated EMA syndrome after 131 I therapy. Corticosteroid might be the effective therapy for myxedema and eye symptoms of EMA syndrome.

Objective To evaluate the utility of MMP9,MPO and sCD40L in detection of the character of coronary artery plaque.Methods From April 2008 to January 2010,118 patients from outpatient of Fu Wai Hospital with chest pain were enrolled.All of them underwent 64 Multiple-detector row spiral computer tomography (64-MDCT),the CT value ＜ 130 Hu patients were enrolled in non-calcified plaque group (71 cases),CT value ≥ 130 Hu patients were enrolled in the calcified plaque group (47 cases).Ninty healthy volunteers were selected as the control group.Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of serum markers,including MMP9,MPO and sCD40L.Levels of MMP9,MPO and sCD40L of each group were compared.ROC curve was used to evaluate the sensitivity and specificity of the markers in diagnosis of non-calcified plaque.Results MMP9,MPO and sCD40L levels of non-calcified were ( 762.25 ± 368.71 ),[ 844.10 (582.00 - 1220.70) ],(9.37 ± 3.15) μg/L,higher than the healthy control group (342.70 ± 178.53),[426.35 ( 283.20 - 592.00) ],(6.55 ± 2.96) μg/L and calcified plaque group ( 483.12 ± 219.09 ),[ 469.00 ( 302.45 - 723.55) ],( 7.24 ± 2.86) μg/L The difference was statistically significant ( F =42.47,H =50.28,F =17.94,all P ＜ 0.01 ). Areas of MMP9,MPO and sCD40L under the ROC curve to predict non-calcified plaque were 0.854,0.792,0.751 respectively,when the identification threshold for non-calcified plaque were 510.13,537.82,7.05 μg/L respectively,the diagnostic sensitivity was 80％,80％,80％ respectively,and specificity was 80％,67％ and 55％ respectively.Conclusion The serum MMP9,MPO and sCD40L levels can help to determine the　character of coronary plaque.

AIM To investigate the effect of Shenfu Injection on atherosclerosis (AS) models of high-fat apolipoprotein E-deficient (ApoE-/-) mice,and to explore its anti-atherosclerosis mechanism through the observation of oxidative stress (OS) variation.METHODS C57 mice were used as controls.ApoE-/-mice fed with 20-week high fat diet were randomly divided into model group,Shenfu group for subsequent 4-week continuous corresponding intervention,after which the mice had their blood lipid levels measured,their levels of MPO and NOX4 identified by ELISA,and their T-SOD activity determined by hydroxylamine method,their MDA level detected by TBA,their plaque formation observation achieved by HE staining of aortic gross and red O of all the aorta,and their Nrf2 mRNA expression detected by real time qPCR method.RESULTS Compared with the control group,the model group manifested with increased contents of TG,TC,LDL,decreased HLD;decreased activity of SOD,increased contents of MPO,NOX4 and MDA,and down-regulated expression of aortic Nrf2 and Keap1 mRNA.Compared with the model group,Shenfu Injection group was observed with no obvious blood lipid level change,but a reduction of plaque area,and an effective inhibition on OS as revealed by improved levels of Nrf2 and Keap1 mRNA.CONCLUSION Shenfu Injection can activate Nrf2 and interfer the relevant enzymes,thus prevents the atherosclerosis progression through OS reduction.

OBJECTIVETo evaluate the effect of tetra-arsenic tetra-sulfide (As4S4) therapy on the corrected QT interval (QTc) in the acute promyelocytic leukemia (APL) patients.

METHODSNinety cases of APL treated with As4S4 were divided into two groups--the remission induction group and maintenance therapy group. Blood arsenic concentration was measured and a 12-lead electrocardiogram (ECG) was simultaneously performed before treatment and after remission in the induction group, and before and 2, 4, 6, 8, 10 courses after the treatment in the maintenance therapy group. QT interval on each ECG was measured and corrected by the Bazett formula.

RESULTSOral administration of As4S4 could lead to the prolongation of QTc both in remission induction and maintenance therapy groups. QTc prolongation was related to the doses of As4S4 and blood arsenic levels. QTc prolongation and its variation range were increased with accumulative doses of As4S4 and the blood arsenic levels. In ten courses maintenance therapy patients, the average abnormal rate of QTc was 37.7%. Blood arsenic concentration was increased slowly with courses, but the variation had no statistical difference (P > 0.05). All the patients whose QTc was abnormal (> or = 440 ms) had neither symptoms nor serious cardiac events, such as ventricular tachycardia and Torsade de pointes and could complete the As4S4 therapy.

CONCLUSIONAlthough As4S4 therapy can lead to QTc prolongation in the treatment of APL patients, it does not preclude the completion of the therapy.

OBJECTIVETo investigate the relationship between the biological features and the treatment efficacy and prognosis in acute myeloid leukemia subtype M2 (AML-M2) patients with chromosome 8 and 21 translocation.

METHODSBy using Cox regression model and Kaplan-Meier analyses, prognostic factors in 54 cases of de novo adult AML with t(8;21) in our institute from 1990 to 2003 were retrospectively analyzed.

RESULTThe complete remission (CR) rates were 81.9% for all M2 patients, 82.4% for patients with normal karyotype, 88.5% for patients with t(8;21) [P > 0.05 for normal karyotype vs t(8;21)], 100.0% for 28 patients with t(8;21) alone and 75.0% for 24 patients with additional chromosome abnormalities (P < 0.01). The actuarial 3 year overall survival(OS) was 26% for M2 patients with normal karyotype, 25% for patients with t(8;21) [P > 0.05 for normal karyotype vs t(8;21)], in whole t(8;21) group, 46.4% for patients with t(8;21) alone and 0% for patients with additional chromosome abnormalities (P < 0.01). Multivariate analysis of prognostic factors showed that chromosome abnormalities besides t(8;21) was the only factor affecting CR, disease-free survival (DFS) and OS. DFS of allogeneic hematopoietic stem cell transplantation (HSCT) and intermediate-dose cytarabine/high dose cytarabine (IDAC) groups were better than the group received routine dose cytarabine as postremission therapy (P < 0.01).

CONCLUSIONAML with t(8;21) is not a single defined AML subset, and patients with additional chromosome abnormalities have a worse prognosis. HSCT and IDAC could improve the outcome. HSCT is the best choice for patients with high risks, especially with additional chromosome abnormalities.

Studies have been shown that intraocular pressure (IOP) shows a seasonal variation, but amount of change differs from study to study. The variability in their results may be due to negligence of factors that can affect IOP. Due to differences in environmental conditions of China than other countries, we investigated seasonal variations in IOP of 103 healthy male Chinese of Shanghai. IOP was measured each month over the course of fourteen months with the Goldmann applanation tonometer. The average intraocular pressures in the winter months were higher than those in the spring, summer, and autumn months. The IOP difference between winter and summer months was found to be 1.4 +/- 0.7 mmHg.This study confirms that season influences IOP. As compared to other nations, effect of seasons on IOP seems to be somewhat less pronounced in Chinese. The possible mechanisms, responsible for the seasonal variation of intraocular pressure, are also postulated.
