ABSTRACT
Objective To explore the effects of different flushing and sealing procedures on blood pressure fluc-tuation in patients receiving norepinephrine(NE) via micro-pump. Methods A total of 40 cases of critically ill pa-tients receiving intravenous infusion of NE via micro-pump,were randomly divided into two groups(20 cases in each group) from March to September,2016. For the experimental group,the liquid medicine in central venous catheter was sucked out,followed by flushing or sealing the tube according to conventional operation method. For the control group,conventional operation method was used to flush or seal the tube. The effects of two methods on arterial blood pressure were compared. Results Overall 423 flushing and sealing events were recorded among 40 cases in this study (209 in the experimental group and 214 in the control group). The fluctuation of blood pressure was small in the experimental group,while patients in the control group had significant fluctuation of blood pressure(P<0.05). Conclusion The new method that sucking liquid medicine out of the central venous catheter before flush-ing or sealing the tube followed by flushing or sealing using conventional operation method can reduce the risk of sudden increase in blood pressure for patients receiving small dose infusion with micro-pump.
ABSTRACT
Through the analysis of current situation of the tension relationship between doctor and patient,this paper expounded that the harmonious management organization theory took the cooperation order as the core of the development of the group organization,and emphasized the running-in process of the internal staffs in the collective group.And it pointed out that the internal cooperation between doctor and patient had the certain cooperation order,and also had obstacles that might cause conflict in cooperation from the perspective of the harmonious management organization theory.This paper analyzed and understood the process of doctor-patient coordination at the group level of harmonious management organization theory,explored and analyzed the obstacles that might cause the conflict during the cooperation process and the reasons in the view of innovation,explored and concluded relevant measures to ease the tension of the doctor-patient relationship,and finally achieved the outcome of maximization of common interests and optimization of treatment effect.
ABSTRACT
Objective To investigate the inhibition mechanism of tetramethylpyrazine combined with cisplatin on angiogenesis in Lewis lung cancer mice and to observe the mechanism of Arresten on angiogenesis in lung cancer. Methods The model of Lewis lung adenocarcinoma mouse xenograft was established in this work, and 40 mice were randomly divided into 4 groups: 0.9% sodium chloride solution group(NS group), tetramethylpyrazine group(TMP group), cisplatin group(DDP group), tetramethylpyrazine plus cisplatin group(TMP + DDP group), 10 mice in each group.Mice in NS group were given 0.2 mL of 0.9% sodium chloride solution, mice in DDP group were given 0.2 mL of 2 mg.kg-1 of cisplatin, mice in TMP group were given 0.2 mL of 100 mg.kg-1 of tetramethylpyrazine, mice in TMP+DDP group were given 2 mg.kg-1 of cisplatin and 100 mg.kg-1 of tetramethylpyrazine, each 0.1 mL .Tumor size was measured every day to calculate the tumor volume.The mice were sacrificed to stripp the subcutaneous tumor after continuous medication. The expressions of Arresten, integrin α1β1 and VEGF were determinated by immunhistochemistry and Western blotting. Results The tumor growth of NS group was the fastest and TMP+DDP group was the slowest. Compared with NS group, the expression of Arresten in the other three groups was increased( P<0.01) , and the TMP+DDP group exhibited the highest expression;at the same time, integrin α1β1 , VEGF in the other three groups was decreased(P<0.01), and the TMP+DDP group exhibited the lowest expression.The expression of integrinα1β1 and VEGF was negatively related to Arresten, and the expression of integrin α1β1 was positively correlated with VEGF. Conclusion TMP can inhibited the growth of Lewis lung carcinoma and angiogenesis. Moreover, in combination with cisplatin, TMP can also improved the effect of chemotherapy and then the survival state of mice. The mechanism of action, which TMP suppress tumor angiogenesis may be through improving Arresten and inhibiting integrin α1β1 and VEGF. And the action mechanism of Arresten may be implemented by inhibiting the expression of VEGF by incorporation with integrinα1β1 or by itself to inhibit the expression of VEGF.

Methods C57 BL/6 mice were subcutaneously inoculated with Lewis lung adenocarcinoma cells , and Lewis lung adenocarcinoma mouse xenograft model was established .Forty mice were randomly divided into four groups:normal saline group(NS group,0.9%NaCl,0.2 ml), TMP group (TMP 100 mg/kg,0.2 ml), DDP group (DDP 2 mg/kg,0.2 ml), TMP plus DDP group (doses as above,0.2 ml totally) with 10 mice in each group.After 2 drug intervention,following 14 days of inoculation , the tumor diameter was measured every two days to calculate the tumor volume .The mice were sacrificed after 14 days of continuous medication , and the subcutaneous tumors were weighed after stripping to calculate the inhibitory rate.The expressions of Mac2-BP and VEGF was detected by Western blot and immunhistochemistry .Results Compared with NS group, the tumor growth rate of TMP group , DDP group and TMP+DDP group was slowed down , and the tumor growth rate in the TMP+DDP group was decreased most significantly .The inhibitory rate of TMP group , DDP group and TMP+DDP group was 25.57%, 45.24% and 66.5%,respectively.Kim, s formula was used to evaluate the synergy of the combined treatment .The q values for TMP +DDP group was 0.85
ABSTRACT
Objective To investigate health status of medical staff and its impacting factors so as to provide useful health guidance. Methods Health examination data from 2 hospitals in Zhejiang province were collected. The medical staff group was classified into 5 subgroups according to the departments; the control group was composed of other mental labors. The health examinations included clinical, laboratory and special testing. SPSS 11.0 software was used for data analysis. Results Compared with the control group, the morbidity rate of the medical staff group was higher, especially in those aged < 50 (χ2 = 6. 651,8. 883, and 7. 446; all P < 0.05 ). All medical staff subgroups showed significant difference in morbidity rate ( χ2 = 39. 099 ,P < 0.05 ). Hyperlipidemia,cervical erosion,and breast hyperplasia were the most common diseases found in medical staff; while the control group developed more breast hyperplasia, hyperlipidemia, and retinal arteriosclerosis. Conclusions Health status of medical staff could not be optimal. Effective health education would be needed to improve life style and relieve stress.
ABSTRACT
Objective To discuss causes, characteristics and clinical treartment measures for negative fluid balance and systemic edema in patients with traumatic hemorrhagic shock. Methods A retrospective chart study was done on 205 cases with systemic edema posterior to traumatic hemorrhagic shock admitted to ICU between May 1994 and August 2002. Results All cases showed systemic edema at various degrees. The survived 173 cases demonstrated spontaneous diuresis and negative fluid balance at different time in the first week but the died 32 ones not. The negative fluid balance and the spontaneous diuresis were not more severe than that in the control group under conditions of age (≥60 years old), injury severity score (ISS ≥16), acute physiological and chronic health evaluation (APACHE) Ⅱ≥12 and Cr≥2.0 g/L ( P
