Objective To evaluate the effect of the early goal-directed therapy (EGDT) on mortality in patients with septic shock, and to analyze the risk factors of mortality.Methods A retrospective controlled study was conducted.Complete clinical data of patients with septic shock admitted to emergency intensive care unit (EICU) of Sichuan Provincial People's Hospital from May 1994 to December 2014 were recorded and analyzed.According to the International Guidelines for Management of Severe Sepsis and Septic Shock (SSC) with the time of promulgation as dividing point, the patients were divided into two groups as before and after the publication of the guideline, i.e.early group (from May 1994 to April 2004) and late group (from May 2004 to December 2014).The patients of the late group were subdivided into 6-hour and 24-hour reaching standard groups and non-reaching standard group according to the time of reaching standard of EGDT.All patients were divided into death group and survival group according to the 28-day survival.The patients in early group were not treated according to EGDT guidance, so only age, the case history of chronic disease, the main site of infection, organ dysfunction, vital signs, urine output, the amount of fluid for resuscitation, blood routine, blood gas analysis, time for starting antibiotics treatment, the use of vasoactive drugs and hormone, etc.were recorded.The central venous pressure (CVP), central venous oxygen saturation (ScvO2), blood lactate (Lac), and the monitor of other parameters of patients in late group were consummated late.The relationship of EGDT compliance standard time and tissue perfusion index recovery time between the two groups of patients was observed.The risk factor for mortality was analyzed by multiple factors logistic regression.Results ① 134 patients were included,and the overall 28-day mortality was 49.25％.② The 6-hour EGDT compliance rate of early group was 0 (0/58),and it was 28.95％ (22/76) in late group (x2 =20.087, P =0.000).Compared with the early group, the 6-hour urine volume in the late group was significantly increased (mL·h-1·kg-1: 1.72± 1.04 vs.0.89±0.24, t =11.950, P =0.001),6-hour mean arterial pressure (MAP, mmHg, 1 mmHg =0.133 kPa) was elevated (64.24±3.90 vs.56.21 ±5.95, t =6.444, P =0.012), the use of antibiotics within 1 hour was increased (76.32％ vs.48.28％, x2 =11.250, P =0.001), the use of vasocative drugs (21.05％ vs.89.66％, x 2 =61.942, P =0.000) and hormone (8.57％ vs.34.48％, x 2 =14.871,P =0.000) were lowered, and the 28-day mortality rate was lowered significantly [34.21％ (26/76) vs.68.96％ (40/58),x2 =15.897, P =0.000].The difference was not statistically significant in the total recovery of liquid volume between late group and early group (mL: 1 856.31±805.81 vs.1 903.1 ± 897.11, t =0.101, P =0.752).③ In all patients, it was shown by single factor analysis that the age, infection sites, altered mental status at admission, white blood cell (WBC) before treatment, 6-hour urine output after treatment, the number of organ with failure, the use of antibiotics within 1 hour, and incidence of acute renal injury (AKI) or acute lung injury/acute respiratory distress syndrome (ALI/ARDS) within 24 hours were risk factors of 28-day death (P ＜ 0.05 or P ＜ 0.01).In the late group, it was shown by single factor analysis that the age, the case history of chronic disease, infection sites, WBC, pH value, Lac, and ScvO2 before treatment, 6-hour urine output after treatment, the number of organ with failure, the use of antibiotics within 1 hour,and incidence of AKI or ALI/ARDS within 24 hours were risk factors of 28-day death (P ＜ 0.05 or P ＜ 0.01).It was shown by the logistic regression analysis that aging [odds ratio (OR) =4.81, P =0.02], failure of 2 organs (OR =28.63,P =0.00) or ≥ 3 organs (OR =62.69, P =0.00) were the independent risk factors for mortality in patients with septic shock.④ The 76 patients of late group were subdivided into three groups, namely 6-hour reaching standard of EGDT group (n =22), 24-hour reaching standard of EGDT group (n =28), and non-reaching standard of EGDT group (n =28).Compared with those before treatment, the Lac after therapy was decreased obviously both in 6-hour EGDT group and 24-hour EGDT group, and the CVP, MAP, and ScvO2 were increased significantly.The Lac in 6-hour EGDT group was lowered more significantly as compared with that in 24-hour EGDT group (mmol/L: 1.64 ± 0.40 vs.3.01 ± 1.13, P ＜ 0.01),while MAP and ScvO2 were increased significantly [MAP (mmHg): 81.82 ± 8.01 vs.69.01 ± 9.63;ScvO2:0.718 ± 0.034 vs.0.658 ±0.036, P ＜ 0.05 and P ＜ 0.01].The urine output in both reaching standard of EGDT groups was more than 0.5 mL·h-1·kg-1, without statistically different significance.The 28-day mortality rate of 24-hour EGDT group was 14.29％, and it was 0 in 6-hour EGDT group.Conclusions Mortality was as high as 68.96％ during 10 years when the period before the use of 2004 SSC, and the mortality rate was lowered to 34.21％ during 10 years during which the early fluid resuscitation treatment was based on EGDT.Aging and failure of more than 2 organs were independent risk factors for mortality in patients with septic shock.Compared with reaching the standard of EGDT within 24 hours,reaching the standard of EGDT within 6 hours can rapidly reverse hypoxic-ischemic tissue, thereby improving the prognosis of the patient with lowering of mortality rate.

Because of lots of ethical problems,military medical triage has been unaccepted by general doctors.But it's adopted by American Army in front of facts of the war.The main principles of the military medical triage are justice and efficiency.They practice the military medical triage through tow steps.First,all patients are assigned into urgent,immediate ,delayed,minimal or ambulatory and expectant status in decreasing order of medical urgency.Second,choosing the model of triage depends on nonaustere,austere or extreme conditions.The ethical issues of American military medical triage focus on four aspects - how to deal with minimally injured patient treatment first,how to treat expectants,how to care for noncombatant casualties and who decide the model of triage.

With the rapid development of healthcare technologies, the improvement of patient health expecta-tions, and the increasing of the government or insurer's financial budget pressure, risk-sharing agreements has be-come the focus of the governments or insurer concerned. This article systematically analyzed Australia, New Zealand, Taiwan risk-sharing agreements from five aspects, including the operation main, scope, classification, application processes and the implementation effects. According to the results of the analysis, we suggests that China should im-prove risk-sharing agreements theoretical basis, diversify risk-sharing agreements models, establish risk-sharing a-greements standardization process and so on.

Objective To investigate the clinical efficacy of different treatment in 35 chronic lymphocytic leukemia (CLL) patients. Methods Patients were treated with different regimen according to Binet stage. Patients at stage A were subcutaneously injected with interferon (3-6) MU/day, consecutive for 5 days every week. The dosage could be reduced to 2-3 times a week in long term maintenance phase after the 6 months loading treatment if there was no disease progression. Those at stage B or C were initially treated with chemotherapy regimen of FC/FC -R or CHOP/COP, and interferon were administered during chemotherapy interval, after complete remission (CR) or partially remission (PR) as maintenance therapy.Results Twenty patients were at stage A and treated with interferon, with 5 patients(25%) achieving partial remission (PR), 14 patients at stable status while no patients acquiring CR. Three of the 5 patients who achieved PR collapsed after 36.3 months at average. Eight of the 14 patients at stable status deteriorated to stage B and received chemotherapy after mean 74 months interferon maintenance treatment. In total, 27 patients in the current observation were finally included at stage B or C. Patients at stage B or C in FC/FC-R chemotherapy regimen achieved CR at 38.9% and total effective rate 77.8%, which were superior to that of CHOP/COP prescription (CR 11.1 %). The mean survival time for patients at stage A, B and C were 155.2,97.5 and 82.9 months, respectively and were statistically significant via Kaplan-Meier analysis method (P =0.032). Ten patients died in this observation, 2 at stage A, 4 at stage B and C, respectively, among whom 9died of infection and 1 for gastric cancer bleeding. The side effects of interferon were generally mild during the long term treatment. Conclusion Patients with CLL need to be individually treated with different regimen by considering disease stage and other prognosis criteria. Interferon could be applied at early phase of CLL and may reduce occurrence of infection after long term treatment.

ObjectiveTo evaluate the application of 18fluoro-deoxyglucose positron emission tomography (FDG-PET) to the staging and predicting outcome in patients with lymphoma.Methods 41 patients with newly diagnosed lymphoma(median age 57 years)were explored with FDG-PET prior to and after 4 cycles of chemotherapy.With a median follow-up of 30 months (range 10-68 months),the value of FDG-PET to staging and predicting clinical outcome was assessed. Results The maximum standardized uptake value (SUVmax) of nodal and extranodal lesions was 9.7±6.9 and 8.4±6.8 respectively prior to treatment.There were significant difference (P＜0.05) in aggressive non-Hodgkin's lymphoma and indolent non-Hodgkin's lymphoma,no significant difference(P＞0.05)in non-Hodgkin's lymphoma and Hodgkin's lymphoma(HL), B-cell neoplasms and T-cell neoplasms,germinal center B-cell-like DLBCL and activated B-cell-like DLBCL. In 41 patients, 22 patients (54 ％)were detected extranodal focus by FDG-PET before chemotherapy. FDG-PET imaging upstaged in 6(15％)of initial lymphoma patients.There were 15 patients (37 ％) in stage Ⅰ and Ⅱ and 26 patients(63 ％)in stage Ⅲ and Ⅳ by FDC-PET scan.1 patient (7 ％) in stage Ⅰ and Ⅱ,6 patient (23 ％) in stage Ⅲ and Ⅳ died of disease progression during follow-up.After 4 cycles of chemotherapy,the FDG-PET was negative in 41％(17/41),positive in 59 ％(24/41) respectively.1 patient(6 ％)died of disease relapse among 17 patients who were FDG-PET negative, 6 patient (25 ％)died of disease progression among 24 patients who were FDG-PET positive during follow-up. Conclusion FDG-PET scanning plays an important role in the pretreatment staging and prediction of the prognosis after 4 cycles of chemotherapy in patients with lymphoma.Thus it may offer the potential for change in treatment paradigms.
