OBJECTIVETo compare efficacy of unilateral external fixators and locking compression plates in treating type C fractures of the distal radius.

METHODSFrom January 2009 to June 2010, 76 patients with distal radius fracture were treated with LCP and external fixators, 54 patients were followed up. Among them, 29 cases were male and 25 cases were female with an average age of 45.31 (ranged, 24 to 68) years old. There were 29 patients in LCP group. According to AO classification, 8 cases were type C1, 7 cases were type C2 and 14 cases were type C3. There were 25 cases in external fixators group. According to AO classification, 6 cases were type C1, 8 cases were type C2 and 11 cases were type C3. Radial height, volar tilt and radial inclination were compared, advanced Gartland-Werley scoring were used to assessed wrist joint function after 6 and 12 months' following up.

RESULTSTwo cases were suffered from nail infection in external fixators group. Fifty-four patients were followed up from 12 to 24 months with an average of 21.3 months. Radial height was (9.60 +/- 0.72) mm, volar tilt was (9.55 +/- 0.80) degrees and radial inclination was (21.40 +/- 0.78) degrees in LCP group,while those were (9.40 +/- 0.70) mm, (9.47 +/- 0.71) degrees and (21.20 +/- 0.73) degrees in external fixtors group, and with no statistical significance (P>0.05). Advanced Gartland-Werley score after 6 months' following up was 3.31 +/- 1.17 in LCP group, 5.56 +/- 1.58 in external fixtors group, and with significant difference (t=-5.99,P<0.05); after 12 months' following up, advanced Gartland-Werley score was respectively 2.66 +/- 1.01 and 3.08 +/- 1.00, but with no statistical meaning (t=-1.55, P>0.05).

CONCLUSIONLCP and external fixtors can receive good curative effects in treating type C distal radius fracture, and LCP can obtain obviously short-term efficacy, while there is no significant difference between two groups in long-term results. For serious distal radius comminuted fracture which unable to plate internal fixation, external fixators is a better choice.

Objective To explore the significance of detecting miR-145 hypermethylation in non-small cell lung cancer (NSCLC). Methods Seventy-five NSCLC tissues and adjacent tissues was collected from May 2012 to January 2015. The methylation status of miR-145 promoter was tested by bisulfite sequencing PCR (BSP) and the expression of miR-145 evaluated by ISH. The correlation between miR-145 methylation and clinical parameters , and the relationship between miR-145 methylation and expression were statistically analyzed. Results The hypermethy-lation ratio of miR-145 in NSCLC tissues was higher than that in the adjacent tissues. Hypermethylation of miR-145 was correlated with NSCLC differentiation stage, but not with gender and age. In NSCLC, miR-145 hypermethyla-tion was negatively related with its expression. Conclusion MiR-145 hypermethylation is closely related with dif-ferentiation stage in NSCLC tissues. MiR-145 hypermethylation may be a potential biomarker for estimating NSCLC differentiation stage.

Objective To investigate the expression and effect of miR-22-3p in non-small cell lung cancer (NSCLC). Methods The miR-22-3p expression level in seventy-six NSCLC tissues and para-cancer tissues was detected by qRT-PCR. The relationship between the expression of miR-22-3p and gender,age,tumor size,histolo-gy grade,pathological type and lymph node metastasis was analyzed. The function of miR-22-3p on the prolifera-tion of NSCLC cells was tested by growth curve assay. Target genes of miR-22-3p were predicted by online software Targetscan. Luciferase reporter assay and qRT-PCR was used to certificate the prediction. Results The expression of miR-22-3p was increased in NSCLC tissues than the para-cancer tissues and was correlated to lymph node metas-tasis. Overexpression of miR-22-3p could suppress the proliferation of A549 cells. Astrocyte-Elevated Gene-1(AEG-1) was predicted to be a target of miR-22-3p. MiR-22-3p was revealed to bind to AEG-13′UTR by luciferase report-er assay. Overexpression of miR-22-3p could inhibit the expression of AEG-1 in A549 cells. Suppression of miR-22-3p could increase AEG-1 expression. Conclusion MiR-22-3p could inhibit the proliferation of NSCLC by tar-geting AEG-1.

AIM:To analyze the effects of oxymatrine(OMT) on the quantity of murine regulatory T cells(Tr cells) in the peripheral blood and mouse lymphocyte proliferation stimulated by Con A,and to probe into the immunological mechanism that OMT treats allergic contact dermatitis(ACD).METHODS:An ACD mouse model stimulated by dinitrofluorobenzene(DNFB) was established.Different dosages of OMT,PBS and hydrocortisone(HCT) were intraperitoneally injected(IP) into the mice.Blood samples were collected at 1 d,7 d,14 d,21 d and 28 d,then the T cells were isolated and marked with anti-CD3,anti-CD4,anti-CD25 three-colored immune fluorescence antibody to detect the quantity of CD4+CD25+ T cells with flow cytometry.The fluorescence intensity changes of lymphocytes which were isolated from mouse's lymph node and co-stimulated by polyclonal stimulator Con A and OMT were examined by carboxyfluorescein diacetate succinimidyl ester(CFDA-SE) staining and flow cytometry.RESULTS:OMT at concentrations of 500,125 and 31 mg/L had the ability to restrain the proliferation of lymphocytes from lymph node in a dose dependent manner.However,OMT at concentrations of 16,8,4 and 2 mg/L promoted the proliferation of T lymphocytes from lymph node,but was not obviously dependent on its concentration.Intraperitoneal injection of OMT increased the numbers of CD4+CD25+T cell in peripheral blood obviously(P

Objective To explore the epidemical pattern of acute schistosomiasis in Poyang Lake area so as to provide the scientific evidence for control-strategy-making. Methods The data of acute schistosomiasis in 12 counties along Poyang Lake from 1960 to 2007, including the data of 2 special investigations from 1982 to 1984 and from 1987 to 1989 were collected and analyzed with the retrospective investigation methods. Results There were 29 864 cases of acute schistosomiasis in 12 counties of Poyang Lake area from 1960 to 2007, accounting for 85.5% of the total acute schistosomiasis cases of Jiangxi Province. The largest number of cases existed in Yugan County, accounting for 18. 7%. The peak of acute schistosomiasis prevalence was in 1987 with 2 088 cases. However, the case of acute schistosomiasis declined significantly, keeping at a low level, since 1990. During the 2 special investigations, the people whose age were lower than 30 years old, were the susceptible populations of acute schistosomiasis (86. 1% and 82. 9% , respectively) , most of them were peasants and students, and the infection rates were 57. 4% and 21.2%, 61.7% and 21. 8%, respectively. Fishing and swimming were the main infection ways, with the infection rates of 43.0% and 44.9% , respectively. The peak season of infection was from April to October. Conclusions The river bank and continent of Poyang Lake are the main infection areas, the spring and autumn are the main epidemic seasons and the susceptible populations are the peasants, fishmen and young students. It is very important to enhance the comprehensive prevention and treatment measures in the key areas and population for schistosomiasis control.

Objective To study the etiology of nosocomial infection and the risk factors in senile patients with acute myelogenous leukemia who received chemotherapy, then to explore the preventive measure. Methods 9lcases of senile patients with AML received 304 times of chemotherapy, then to analyze the rate of nosocomial infection, the infection site, the result of etiological examination and the relationship between the rate of nosocomial infection and the absolute of neutrophil count in peripheral blood and the duration of agranulocytosis. And then the results were compared with the non-senile patients with AML. Results The statistical indicators of nosocomial infection in senile patients with AML was higher than those younger ones. The rate of infection in lower respiratory tract, oral, alimentary canal, skin, anal area and the rate of sepsis in senile people was higher than those younger ones.Positive rate of fungal infection of senile patients was higher. The nosocomial infection in the patients whose absolute neutrophil count in peripheral blood was no more than 0.5×l09/L,and prolonged over 7 days was specific higher. Conclusions Senile patients with AML is the high risk group for nosocomial infection. Age, chemotherapy, the neutrocytopenia level and prolonged time are related to the nosocomial infection in senile patients with AML. It is necessary to take positive measure to control nosocominal infection and advance life quality of senile patients.
