Objective To explore the value of early arterial blood lactate clearance rate and central venous oxygen saturation (ScvO2 ) monitoring in patients with severe pneumonia .Methods A total of 56 patients with severe pneumonia treated during the period from January 2012 to December 2013 were reviewed retrospectively .The arterial blood lactate concentration and ScvO2 were determined immediately after admission to hospital and 6 hours after admission to calculate the 6‐hour lactate clearance rate .APACHE II score was evaluated at the same time .The patients were divided into three groups according to APACHE II score:10 to ＜20 (group A) ,20 to ＜30 (group B) ,≥30 (group C) .The three groups were compared in terms of early arterial blood lactate clearance rate and ScvO2 and estimate their association with the prognosis of patients .Results The initial arterial blood lactate concentration did not show significant difference between the three groups (P>0 .05) .The early lactate clearance rate and ScvO2 at 6 hours in group C were significantly lower than in group B .The values in group B were significantly lower than in group A (P＜0 .05) .The mortality rate in group C was significantly higher than in group B ,and the mortality rate in group B was significantly higher than in group A (P＜0 .05) .The APACHE II score of the dead patients was higher than that of the suevivors ,but early lactate clearance rate and ScvO2 level were lower than those of the survivors (P＜0 .05) .APACHE II score was negatively correlated to early lactate clearance rate (r=0 .661 ,P＜0 .01) and early ScvO2 level (r=0 .579 , P＜ 0 .01) .Conclusions Early lactate clearance rate and ScvO2 level are good indicators to reflect the severity of disease and predict the outcome in the patients with severe pneumonia .

Objective To study action mechanism of rhamnocitrin in Oxytropis Falcata on enhance the immune function. Methods Kunming mice were randomly divided into blank control group, model group, positive control group, traditional Chinese medicine high, medium, and low dose groups. All treatment groups received gavage with relevant medicine for 10 days. From the 8th day, blank control group received intraperitoneal injection with normal saline, while other groups received intraperitoneal injection with cyclophosphamide for 3 days. Through macrophages carbon clearance test, macrophage phagocytosis of chicken erythrocytes test, and immunosuppressive mice organ index detection, effects of rhamnocitrin in Oxytropis Falcata on nonspecific immune function of immunosuppressive mice were observed. Results Compared with model group and blank control group, traditional Chinese medicine high, medium, and low dose groups could improve the phagocytic activity of immunosuppressive mice, clearance index, and phagocytic coefficient (P<0.05), and increase the organ index of the thymus and spleen. Compared with the positive control group, the efficacy of traditional Chinese medicine high, medium, and low dose groups was low. Conclusion Rhamnocitrin in Oxytropis Falcata can enhance the immune function, improve the formation of spleen cells of mice serum hemolysin of chicken red blood cell immune.

Objective To study the effects of Wortmannin, inhibitor of PI3K and SB202190, inhibitor of P38 MAPK and PD98059, inhibitor of ERK1/2 on the migration of epidermal growth factor (EGF)-induced vascular smooth muscle cells (VSMCs). Methods There were fives groups in this experiment, including control group, EGF group, PD98059 (PD) group, SB202190(SB) group and Wortnannin (WT) group. The migration rate of the VSMCs was measured by wound healing assay. Results At the 24th hours after wounding, there was obvious migration in EGF group compared to control group. The migration of VSMCs was significantly inhibited in PD group, SB group and WT group compared to the EGF group, but there were no significant difference among three inhibitor groups. At the 30th hours after woun-ding, there was still obvious migration in EGF group compared to control group. The migration of VSMCs was significantly inhibited in the three iuhibitors group compared to the EGF group, and there were significant difference among three inhibitor groups. Furthermore, inhibiting effect on VSMCs in SB group was more obvious compared to PD group and WT group. Conclusion These results suggested that the migra-tion of EGF-induced VSMCs may play a role through PI3K, P38 MAPK and ERKI/2 signal pathways, and the effect of P38 MAPK signal pathway is very important.

OBJECTIVESTo explore the significance of noninvasive central blood pressure detection in blood pressure management and vessel function assessment of hypertension.

METHODSA total of 348 subjects were recruited in the study and A-pulse CASP software were derived to measure the parameters of CASP and vessel function. The recruited subjects were divided into different groups for analysis according to age and disease.

RESULTS(1) CASP in hypertension group were both higher than those in normal group, while RAI and PRT lower. (2) Hypertensive patients of which brachial blood pressure were controlled have lower CASP and RAI than those above the level. (3) Hypertensive patients whose brachial blood pressure were controlled have significantly higher CASP than normal subjects.

CONCLUSIONSCentral blood pressure is more reflective of actural blood pressure and vessel function. Enhanced control of CASP in hypertensive patients contributes to improving vessel compliance.

Objective To build a simulation model for outpatients queuing,using data from a general outpatient cardiovascular clinic of a general hospital in Shanghai and different rules in the process.The study employs time-interval controlled mode for appointment registration,for the purpose of analyzing characteristics of different queues.Methods Extraction of data of the clinic in a given month by means of HIS system to determine the parameters of the queuing models.Building the simulation model with Matlab to develop the plan of mixed queues and that of discrete queues,for analyzing the waiting time variations,with different number of doctors on duty and different number of appointments in one time interval.Resnlts In the Monday mornings for example,the mean waiting time of appointments or no-appointments are calculated by simulation with different queuing rules,different number of doctors on duty and different appointment quantities of one time interval.Conclusion The mean waiting times of appointments and no-appointments can be both sizably cut short by means of time-interval controlled appointment; different queuing plans are recommended for different departments; the simulation model should be further verified and optimized in practice.
