Objective To investigate the effect of budesonide inhalation combined with azithromycin in treatment of children with mycoplasma pneumonia and the corresponding clinical nursing pathway.Methods From February 2010 to 2011,100 cases of children patients with mycoplasma pneumonia (all with budesonide inhalation combined with azithromycin) were randomly divided into the experimental group and the control group with 50 patients in each group.The experimental group adopted clinical nursing pathway,while the control group underwent routine care.After one or three-month follow-up,forced vital capacity (FVC),forced vital capacity 1s (FEV1),peak expiratory flow values (PEF) and other pulmonary functional indexes and clinical efficacy were compared between two groups.Results The clinical effective rate of the experimental group was 94％,higher than the control group.FVC,FEV1,PEF changes in the experimental group were better than the control group.Conclusions Budesonide inhalation combined with azithromycin in treatment of mycoplasma pneumonia in children has good effect,coupled with the clinical nursing pathway can effectively improve lung function,reduce the incidence of adverse reactions during treatment,significantly improve the prognosis,should be used widely in clinic.

Imatinib mesylate,as the first generation Bcr-Abl tyrosine kinase inhibitor,has brought revolutionary treatment for Philadelphia chromosome (Ph)-positive chronic myelogenous leukemia (CML);it has been recommended as the first-line treatment for CML by NCCN Practice Guidelines in Oncology in 2008 and European LeukemiaNet(ELN) criteria.However,imatinib has three limitations:first,it is expensive and can not be stopped if efficancy to be maintained;Second,some 20%~30% of patients develope resistance to imatinib;and third,the CML patients can not be cured with imatinib.Taking into consideration of the situation in China,we recommend individual therapy using TKI,HSCT,interferon and cytotoxic drugs for CML patients in China.

Objective The objective of this study was to investigate effects of miR-34a on the proliferation,invasion and migration of colon cancer SW480 cell and its possible mechanism.Methods miR-34a overexpressed lentivirus and empty virus vector were transfected into SW480 cells and untreated cells were used as blank control group.Real-time PCR was used to detect the expression of miR-34a in each group.The cell proliferation was detected by CCK8 assay.The cell migration and invasion ability were detected by wound healing and transwell assays.The expression of E-cadherin and Vimentin protein was detected by Western blotting.Results Compared with the empty virus vector group and the blank control group,the expression of miR-34a was increased in the transfected cells,and the cell proliferation efficiency,invasion and migration ability were decreased in the transfected cells (P ＜ 0.05).miR-34a significantly increased the expression of E-cadherin protein and decreased Vimentin protein expression in the transfected cells.Conclusion miR-34a can inhibit the proliferation,invasion and migration of colon cancer SW480 cells,and affect the expression of E-cadherin and Vimentin.MR-34a is expected to be a potential molecular target for the metastasis and recurrence of colorectal cancer.

Objective To investigate the effects on knee function between patella plasty and patellar replacement in total knee arthroplasty.Methods From August 2010 to November 2010,48 patients (69 knees) of osteoarthritis performed TKA were covered in this study.All the patients were randomly assigned to the following two groups:one group contained 24 patients (34 knees) performed patella plasty,and the other group contained other 24 patients (35 knees) performed patellar replacement.There was no significant difference between the two groups in age,weight,height,BMI,patellar score and the American Knee Society Score (KSS).Every patient was followed up for 6 weeks,3 months,6 months,one year,and two years.All the results,which were used to compare the difference between the two groups,in KSS knee score,knee function score,patellar score,the incidence of anterior knee pain,and imaging findings.Results In this clinical study,20 patients (30 knees) in patellar replacement group and 20 patients (29 knees) in patella plasty group were followed up.No significant difference was found in the postoperative KSS knee score between 2 groups at each time point.The KSS knee function score in replacement group was significantly higher than that in arthroplasty group at 6,12 and 24 months after operation.The incidence of anterior knee pain after the surgery in replacement group was significant different from the plasty group at every time point after operation.There was no significant difference in tibiofemoral angle,patellar ligament ratio,patellar tilt angle,congruence angle and lateral patellar displacement between two groups at last follow-up.Conclusion Total knee arthroplasty with patella replacement can improve both knee function and patella function,and reduce the incidence of postoperative anterior knee pain.

Objective:To determine the relationship between injury risk and alcohol drinking. Methods:Totally 531 patients (age≥18 years) who were treated for the ifrst time and came to the emergency room within 6 h atfer the injury were included. hTe American National Institute of Health questionnaire was used to investigate the trauma type, intentional injury, drinking before the injury, drinking volume, and drinking history in the past years and so on. hTe case-crossover method was used to analyze the data and relationship between alcohol drinking and injury.Results:Compared with the non-drinkers, subjects who drank alcohol 6 h before the injury had a higher risk of intentional injury (OR=2.79, 95%CI: 1.61–4.84). Male, drunken, patients with positive alcohol test results were more likely to suffer from intentional injury. Compared with the non-drinkers, victims who drank alcohol 6 h before injury had a higher risk of injury in traffc accidents (OR=2.41, 95%CI: 1.29–4.51). Compared with the non-drinkers, subjects who drank alcohol 6 h before injury had a higher risk of injury (OR=11.86, 95%CI: 5.48–25.65). Subjects who drank more than 6 standard drinks of alcohol 6 h before injury had much higher risks than non-drinkers (OR=24.52, 95%CI: 5.84–102.86). Conclusion:Alcohol drinking before injury is associated with increased the risk of trauma, intentional injury and injury related to traffc accidents.

Objective To investigate the protective effect of normal hematopoietic and without causing the increase of relapse rate of amifostine in patients with acute myeloid chemotherapy.Methods One hundred and forty-two acute myeloid leukemia(AML) patients were selected and divided into combination group(n =56) and chemotherapy alone group (n =86).Hematological toxicity and non-hematologic toxicity,response rate,duration of response of patients were prospective,non-randomized,case-control study.Results Fifty-six patients in combined group included 30 male and 26 female patients,and 18 patients in high risk stage and 32 patients in intermediate risk stage and 6 patients in low risk.The median age was (35.14 ± 14.42) year in combination group.Chemotherapy alone group included 58 male 28 female patients,and 14 patients in high risk and 64 patients in intermediate risk and 8 patients in low risk.The median age was (46.58 ± 16.99) year.There were no significant difference between two groups in terms of gender (P =0.318) and risk stage(P =0.262).But more young patients were in combination group compared with chemotherapy alone group and there was significant difference(P =0.004).In combination group,42.9％ (24 cases)patients got high Ara-C dose and 32.1％ (18 cases) patients got high HAA dose chemotherapy compared with control group (14.9％ (12 cases)and 20.9％ (18 cases)).The during periods of platelet with ＜20 × 109/L in combination was 0(0,7) day,lower than that in chemotherapy alone group (9 (4,14),P =0.01).Meanwhile the volume of platelet infusion in combination group was less than that in chemotherapy alone group and the nadir of platelet4(0(0,3) U vs.4(1,6) U,P =0.02).No statistic difference was found in two groups regarding of non-hematological side effects and the relapse rate (before and after treatment,combination group:96.4％ (54/56) ; Chemotherapy alone group:98.8 ％ (85/86) ; P=0.062).Conclusion Amifostine may provide protection for AML patients,can short duration of thrombocytopenia,reduce platelet transfusions,and other side effect was no significant difference.

Objective To investigate muli-leaf collimator (MLC)-defined small field output factors calculated by the treatment planning system (TPS), and to study the measuring method of small field output factors verified by 0.015 cc PinPoint ionization chamber.Methods Eight medical accelerators for intensity-modulated radiation therapy (IMRT) were investigated in Henan province, and TPS-calculated output factors for various small fields (6 cm ×6 cm,4 cm ×4 cm,3 cm ×3 cm and 2 cm ×2 cm) were compared with published values recommended by IAEA.If the relative deviation was more than ± 3％ for the 2 cm ×2 cm field size and ±2％ for the fields of 6 cm ×6 cm, 4 cm ×4 cm and 3 cm ×3 cm, which was beyond the scope of IAEA allowed, the output factors will be measured and verified using 0.015 cc PinPoint ionization chamber and Unidos electrometer.Results TPS-calculated small field output factors for eight medical accelerators were compared with published values.The relative deviation of small field output factors for five pieces of equipment, which accounted for 62.5％ of the total, met the IAEA's requirement, while the other three, which accounted for 37.5％ of the total, did not.After measuring with PinPoint ionization chamber, the results from only three pieces of equipment met minimum IAEA's requirement.Conclusions MLC-defined small field output factors calculated by TPS for some medical accelerators in Henan need to be measured and corrected using micro-ionization chamber, and the measured values could be taken as the basis of radiation treatment planning.
