Objective: To study the curative effect of Shengmai injection(生脉注射液) and composite Danshen injection(复方丹参注射液) on acute septic cardiomyopathy(ASC).Methods: Sixty patients(clinically) diagnosed as ASC were randomly divided into two groups: treatment group and control group.All the patients received western routine treatment,and Shengmai injection and composite Danshen injection were added to the patients in the treatment group once per day for 14 days.Cardiac troponin(cTn),electrocardiogram(ECG),clinical synthetic curative effect and amelioration rate of traditional Chinese medicine syndrome scores as well as inflammatory indexes including C-reactive protein(CRP),procalcitonin(PCT) and white blood cell count(WBC) were observed after treatment.Results: The levels of cTn,ECG,clinical synthetic curative effect and amelioration rate of traditional Chinese medicine syndrome scores were more improved in the treatment group than those of the control group(all P

Objective To analyze the normal lung dose-volume histogram(DVH) varieties in the former and later period(P1 and P2)of three dimensional conformal radiation therapy(3DCRT) plans and the compound (Pc) plan in non-small cell lung cancer(NSCLC),and to access the feasibility to modify the target volume during the treatment course.Methods Twenty-one NSCLC patients who had received accelerated hyper-frationation 3DCRT in P2 were included in the study.Both of the P1 and P2 plans were redesigned to a total dose of 70 Gy with V20 smaller than 35%.When the target volume was modified and P2 plan was rede signed using accelerated hyper-frationation 3DCRT of 30 Gy after P1 plan of 40 Gy,the Pc plan was compoun ded by transmitting the parameters(such as target volume,irradiation field and dose) of P1 plan into P2 plan. Total lung volume and target volumes(GTV,PTV) of P1 and P2 were evaluated.MLD,V5,V10,V20 and V30 of P1,P2 and Pc were calculated.Results The total lung volume in P1 and P2 plans was not significantly dif ferent(t = 0.19,P = 0.850).The volumes of GTV,PTV in P2 were obviously smaller than P1 (t = 2.88,P = 0.009 ; t = 4.01 ,P = 0.001) .When comparing P2 with P1 ,MLD were 16.5 Gy Vs 17.8 Gy (t = 2.60, DOI:10.3760/cma.j.issn.1004-4221.2009.01.057 P = 0.017),V30 was significantly decreased (t = 2.19,P = 0.041),but V5,V10 and V20 had no significant difference.Similar differences were found in MLD,V5 ,V10 ,V20 and V30 when comparing Po to P1.P2 plans had significantly smaller MLD,Vs,V10,V20 and V30 than Pc plans.Fourteen patients with decreased PTV were further analyzed.The V30 and MLD decreased significantly (t = 3.00,P = 0.0 I 0;t = 2.38,P = 0.033), but V5 ,V10,V20 had no difference when comparing P1 and P2 plans.Among these 14 patients,the V10 and V30 decreased significantly(t = 2.76,P = 0.033 ; t = 3.60,P = 0.011) when P2 plans were generated using the same field number and beam angles in P1 plans in 7 patients.The parameters were similar in P1and Pc plans,but increased significantly when comparing to P2.Various parameters were the same among P1,P2 and Pc plans when P2 plans were designed using 1-2 different fields and angles in the other 7 patients.The differ ences were not significant between P1 and P2 plans in 7 patients with the same or increased PTV.Expansion or contraction of PTV significantly influenced MLD and V2o (r =-0.62,P = 0.03 ; r = O.48,P = 0.029). Conclusions When the tumor regresses,the high dose volume of the lung decreases with modifying the tar get volume and replanning in the later period using accelerated hyper-frationation 3DCRT.The low dose vol ume of the lung may decrease if the field orientations are same throughout the treatment.It is rational to eval uate the normal lung DVH of the whole plan when the physical parameters of the later period plan are the same as the former one.

Objective Cell therapy is a possible effective way to treat myelination disorder diseases.Cell therapy needs to apply a method for culturing oligodendrocyte precursor cells.Therefore,this study was to develop a stable,efficient and economical method for obtaining human oligodendrocyte precursor cells (OPCs) in order to provide cell required for clinical treatment.And this will provide a new option for clinical applications.Methods Human OPCs were obtained through magnetic bead sorting and cultured in OPCs proliferation medium.For a short-time (2,4,6,8days) and long-time culture,morphology of OPCs was observed.The fourth generation of OPCs was analyzed for expression of OPCs specific markers O4,Soxl0 and platelet derived growth factor alpla receptors(PDGFαR) and the capacity to differentiate into oligodendrocytes by immunofluorescence staining.At the same time,the effects of B27 and N1 on OPCs growth state were inspected as well.Results For a short-time culture,OPCs had typical bipolar or tripolar morphology and proliferated in good condition.For a long-time culture,all 4 generations OPCs had typical bipolar or tripolar morphology;the fourth generation OPCs highly(＞ 90％) expressed 04,Sox10 and PDGFαR,after induction,OPCs could be differentiated into oligodendrocytes.After 4 generations of long-time culture,OPCs already maintained the original sharp,high purity and had the capacity to differentiate into oligodendrocytes.It was indicated that this culture system was suitable for human OPCs for a long-time culture.Conclusions Overall,using this culture system,isolated human OPCs not only can be stably cultured and proliferated in vitro,but also have the capacity to differentiate into oligodendrocytes.From this reproducible method,a large number of human OPCs can be stably obtained in vitro as convenient as possible.And this will provide a new option for clinical applications.This method uses fewer cytokines.Therefore,this method will provide stable,efficient and economical OPCs for cell therapy of myelination disorders or myelin damage diseases.

Objective: To investigate the relationship between prognosis and alteration of oxygen(utilization) coefficient(O_2UC) in patients with sepsis.Methods: Sixty critically ill patients were divided into(sepsis)(n=30) and nonsepsis(n=30) groups,and 30 healthy controls were selected as normal control group.Gas analysis of arterial blood and central venous blood and calculation of O_2UC(O_2UC=arterial oxygen(saturation-venous) oxygen saturation/arterial oxygen saturation) were carried out at 8 o′clock in sepsis and(non-sepsis) groups on admission and 1,2,3,5,7 and 10 days after admission,and gas analysis of arterial blood and central venous blood was carried out only once in the controls.Results: On admission and 1 day(after) admission,O_2UCs in sepsis and non-sepsis groups were significantly higher than that of control group(both P0.05)).When O_2UC in critically ill patients persisted higher than 55% for 12-24 hours,the prognosis of the patients was poor and had a tendency to die in a short time.From the 2 nd day after admission,O_2UCs in sepsis and non-sepsis groups were lower than that in control group,and O_2UC in sepsis group was obviously lower than that in non-sepsis group(all P0.05),but from the 2 nd day after admission,O_2UC in sepsis group remained at a lower level compared with that in control group(all P

Objective To investigate the role of three-dimensional (3D) radiotherapy to the thoracic primary tumor in non-small cell lung cancer (NSCLC) patients with bone metastases during chemotherapy with concurrent 3D radiotherapy.Methods From 2003 to 2010,the clinical data of 95 stage Ⅳ NSCLC patients with bone metastases were collected.All patients received 3D radiotherapy to the thoracic primary tumor and at least 2 cycles of chemotherapy.Of the 95 patients,47 had only bone metastases,and 48 had metastases to bones and other organs.The Kaplan-Meier method was used to calculate overall survival (OS) rates.The log-rank test was used for survival difference analysis and univariate prognostic analysis.The Cox regression model was used for multivariate prognostic analysis.Results The follow-up rate was 95％.The 1-,2-,and 3-year OS rates were 44％,17％,and 9％,respectively.The univariate analysis showed that radiation dose to the planning target volume (PTV) of primary tumor of ≥ 63 Gy,response to treatment of primary tumor,and at least 4 cycles of chemotherapy were favorable prognostic factors for OS in all patients (P =0.001,0.037,and 0.009).Radiation dose to the PTV of primary tumor of ≥ 63 Gy remained the favorable prognostic factor for OS in patients with only bone metastases and those with metastases to bones and other organs (P =0.045 and 0.012).Among patients with only bone metastases,those with T1 + T2 primary tumors had longer OS than those with T3 + T4 primary tumors (P =0.048).The multivariate analysis showed that radiation dose to the PTV of primary tumor of ≥ 63 Gy and metastases to bones only were independent favorable prognostic factors for OS in all patients (P =0.036 and 0.035).Conclusions For NSCLC patients with bone metastases,3D radiotherapy to the thoracic primary tumor and its dose play an important role in improving OS during chemotherapy with concurrent 3D radiotherapy.

ObjectiveTo prospectively investigate the impact of short-time response on survival of concurrent chemotherapy and thoracic three-dimensional radiotherapy (CCTTRT) for stage Ⅳ non-small cell lung cancer (NSCLC). Methods From Jan.2003 to Oct.2010,201 patients with pathologically or cytologically proven stage Ⅳ NSCLC were included.All patients received platinum-based chemotherapy.Of the 167 patients eligible for analysis,the median number of chemotherapy were 4 cycles.The median dose for planning target volume (PTV) of thoracic primary tumor was 63 Gy.Response was scored according to WHO criteria. Survival was calculated by Kaplan-Meier method and compared using the Logrank. Cox regression model were used to examine the effect of response on overall survival.ResultsThe follow-up rate of 201 patients was 97.5％.with 201,170 and 134 patients finished ＜ 1,1 -2 and ≥3 years' follow-up.For the 167 patients eligible for analysis,the CR,PR,NC and PD rate of primary tumor was 5.4％,65.9％,21.0％ and 7.7％,respectively.The effective group ( CR + PR) and ineffective group ( NC + PD) was 71.3％ and 28.7％,respectively.The median survival time (MST) for patients with CR,PR,NC and PD was 22.6,13.4,8.8 and 4.8 months,respectively ( χ2 =44.79,P =0.000).The MST for effective and ineffective group was 13.9 and 7.6 months,respectively in the whole group ( χ2 =8.3 0,P =0.004 ),12.1months and 7.3 months in those treated with 2 - 3 cycles chemotherapy ( χ2 =7.71,P =0.007 ),and 13.9months and 7.9 months in those treated with 2 -5 cycles chemotherapy and radiation dose to PTV ≥36 Gy ( χ2 =4.00,P =0.045 ).No significant MST difference was detected between patients of effective group and ineffective group treated with 4 -5 cycles chemotherapy ( χ2 =0.67,P =0.413),or those treated with 4 -5 cycles of chemotherapy and radiation dose to primary lesion ≥36 Gy (χ2 =0.00,P =0.956).Multivariate analysis showed that 4-5 cycles of chemotherapy and CR and PR achieved in primary tumor (β =0.182,P=0.041 ) were independent favorable factors for survival. Conclusion CCTTRT can improve local control,and prolong the survival time for Stage Ⅳ NSCLC.

Objective To investigate the dosimetric influence of pure carbon fiber treatment tabletop of Elekta Precise new linear accelerator in radiotherapy.Methods Surface-axis distance (SAD) technology was employed for the measurement.Two groups of fields were set and both of them were SAD opposed portals ( one of them went through the tabletop,while the other did not).A PTW electrometer and a 0.6 cm3 Farmer ionization chamber were utilized for comparison measurement.Then dose attenuation of the main table board,extended body board,the extended board for head,neck and shoulders,and the joints of these boards were calculated.Results Under the energy of 6 MV,the dose attenuations of the following locations were:1.4％ - 7.2％ at the main treatment table board; 2.8％ - 38.7％,1.4％ -30.1％,1.5％ -20.8％ and 1.4％ - 11.2％,respectively at distances of 1,4,7 and 8 cm from the joint of the main table board ;0.5％ - 5.0％ at the extended body board; 4.7％ - 15.4％ at distance of 1cm from the joint of the extended body board; 0.5％ -3.3％ at the neck position of the extended board for head,neck and shoulders; 5.3％ - 16.7％ at the shoulder positions; and 6.8％ -30.4％ at the joint between the extended boards and the main table board.Conclusions The dose attenuations of the new linear accelerator pure carbon fiber treatment tabletop vary at different locations. Considerable higher attenuations are observed at the table board joints than other locations.

ObjectiveThis study evaluates the feasibility of intensity-modulated radiation therapy (IMRT) to treat patients with 1 -5 brain metastases from non-small cell lung cancer (NSCLC).Methods 30 IMRT patients with brain metastases for NSCLC studied retrospectively.Whole brain radiotherapy plus three-dimensional conformal radiotherapy (WBRT + 3DCRT) and WBRT plus stereotactic radiotherapy ( WBRT + SRT) plans were generated.Planning target volume ( PTV ) and organs at risk dose were measured and compared by dose volume histogram.Differences were analyzed in the three techniques by Wilcoxon Z -test.Results D99％ of the shoulder ( D99％-D90％ ) from IMRT were higher than from WBRT +3DCRT and WBRT+SRT in all cases.From D15％ of slope (D90％-D10％) to D5％ of tail (D10％ -D1％ ),IMRT were lower than WBRT + 3DCRT and WBRT + SRT ( Z =- 4.72,P =0.000 and Z =- 4.72,P =0.000).D10％ and D5％ of IMRT were (35.1 ±1.42) Gy and (37.7 ±2.91) Gy,WBRT +3DCRT were (36.5±2.86) Gy and ( 39.1 ± 3.56) Gy ;WBRT + SRT were (36.2 ± 2.57) Gy and ( 38.7 ± 3.67) Gy.IMRT vs WBRT+ 3DCRT and WBRT + SRT were significant ( Z=-3.18,-3.18,P=0.001,0.001 and Z=- 4.11,- 3.02,P =0.000,0.002) in 13 patients with 3 - 5 brain metastases.The total mean monitor units were 14756.3,9614.8 and 9043.2 for IMRT,WBRT +3DCRT and WBRT + SRT plans,respectively,with a 38.7％ reduction from IMRT to WBRT + SRT (Z =-4.78,-4.78,P =0.000,0.000).The brain doses around metastases were similar in the three techniques with 1 -2 metastases,but IMRT was the best with 3 -5 metastases.ConclusionsIMRT can advance brain metastases dose and improve the planning target minimum dose and spare the dose around brain metastases.Only IMRT is the best choice for just sparing the dose around brain metastases among 3 -5 brain metastases.
