Objective To compare the sedative effects and pharmacoeconomic profiles of two kinds of combination of dexmedetomidine in traumatic brain injury patients.Methods94 cases of traumatic brain injury from February 2015 to September 2016 were selected and randomly divided into two groups including A group(47 patients) and B group(47 patients).All patients received the same nursing intervention before and after operation.Patients in group A were given right of dexmedetomidine combined with propofol drug therapy, patients in group B were given dexmedetomidine combined with midazolam drug treatment.To maintain the agitation score (SAS) in the standard state of two~four and efficiency of sedation, the mean arterial pressure (map), respiratory rate (RR), heart rate (HR), oxygen saturation (SpO2), arterial carbon dioxide partial pressure (PaCO2), central venous pressure (CVP) Glasgow Coma Score (GCS) and pharmacoeconomic profiles were tested in all patients.ResultsAll patients in two groups achieved the expected sedative effect and analgesia scores.However, A group showed a greater decrease in MAP, RR and HR after sedation as compared to B group.In two groups, there was no significant difference was observed in pulse oxygen saturation (SpO2),partial pressure of carbon dioxide in artery(PaCO2), central venous pressure(CVP)or GCS score before and after sedation.Dexmedetomidine combined with MI of alprazolam treatment phase compared with dexmedetomidine and propofol regimen is more economical, and the difference has statistical significance (P<0.05).ConclusionThe effects of dexmedetomidine combined with propofol and dexmedetomidine combined with midazolam two regimens can achieve good sedative effect.But combined with propofol group compared to midazolam combined with group of respiratory and circulatory system have better inhibitory effect, also in drug economics angle, midazolam midazolam combined with group than that of propofol combined with group is more economical, patients taking lower cost.

Objective:To compare the microbial count method described in Chinese Pharmacopoeia ( ChP) 2010 edition and 2015 edition. Methods:The bacterial count and total aerobic microbial count for 15 samples of Jingfang granule with the same batch were tested respectively by the method described in ChP 2010 edition and 2015 edition, the average number, uncertainty, colony distribu-tion range of samples and qualified rate from the two testing items were analyzed and compared. Results:The average number of colo-nies for the bacterial count and total aerobic microbial count was 720 and 830 cfu·g-1 , the expand uncertainty of 95％ confidence in-tervals was 0. 067 and 0. 061, the colony distribution range of samples was 620-840 cfu·g-1 and 720-960 cfu·g-1 , and the qualified rate was 90％ and 100％, respectively. Conclusion:The microbial count method described in Chp 2015 edition is more sensitive with more reasonable result evaluation, which can guarantee the stability of inspection reports.

Objective To discuss the nursing measures for patients who are receiving percutaneous antegrade ureteral stent implantation for ureteral stricture.Methods A total of 35 patients with ureteral stricture,who were treated with percutaneous antegrade ureteral stent implantation,were included in this study.The nursing care for these patients included the following measures:comprehensive preoperative ward nursing and nutritional support therapy;active preparation,cooperation and monitoring of vital signs during operation;strict postoperative dietary guidance,body position guidance,observation and nursing of complications,and discharge guidance.Results Successful implantation of ureteral stent with single procedure was accomplished in all 35 patients.Mter the procedure,the renal function was markedly improved,when compared with the preoperative data the difference was statistically significant (P＜0.05).The complications,including soreness of waist,lumbago,bladder irritation,hematuria,urinary tract infection,etc.were effectively relieved by positive nursing intervention measures.Conclusion Comprehensive,thoughtful and meticulous nursing care is an important guarantee to ensure a successful percutaneous antegrade ureteral stent implantation for ureteral stricture as well as to reduce the postoperative complications.(J Intervent Radiol,2017,26:277-280)

Comparing the definition,classification,quantity,core capacity construction and the supervision mode of Chinese and the United States specialist nurses,there was a gap between them.The training for the specialist nurses in China was at the initial stage.The advanced experience should be learned from America to provide the reference for building the core capacity and supervision mode of the specialist nurses.

Objective To investigate the changes of fractional exhaled nitric oxide (FENO)) and their relation with lung function in bronchial asthma.Methods FENO and forced expiratory volume in the first second (FEV1) were measured during the periods of acute onset,chronic persistence and paracmasis in 54 patients with asthma and 19 healthy persons.Results There were significant differences in the levels of FENO and FEV1 among the course of acute onset [(57.59 ± 32.24) ppb and (1.72± 0.33) L],chronic persistent course [(40.02 ± 15.68) ppb and (2.41 ± 0.23) L],paracmasis [(26.71±6.07) ppb and (2.82±0.29 )L]and control[(14.74±3.42 ) ppb and (2.93±0.13)L] (F=19.555,163.096,P＜0.01) except for the levels of FEV1 between paracmasis and control group(P＞0.05).The negative correlation between FENO and FEV1 was found in the course of acute onset(r=- 0.666,P =0.005 ),but not in the chronic persistent course ( r =- 0.288,P =0.176) and paracmasis(r=-0.246,P=0.457).Conclusions The level of FENO is increased and may be useful to evaluate control degree in patients with asthma.

OBJECTIVE:To study the influence of different herb composition on content of aconitine in Rhubarb and Aconite Decoction.METHODS:On the basis of Rhubarb and Aconite Decoction,different prescriptions were made up and different de?cocting technics were adopted,then the content of aconitine was determined with UV-spectrophotometry.RESULTS:The content of aconitine in mixture of decoctions of single herb decreased about20%and the content of aconitine in the decoction of combined herbs decreased about45%compared with that in decoction of single Aconite.Combination of Asarum with Aconite showed no influence on the content of aconitine.CONCLUSION:Rhubarb can control the toxicity of Aconite in Rhubarb and Aconite Decoction.

This study is to assess the efficacy of BPCBG on the decorporation of uranium (VI) and protecting human renal proximal tubular epithelial cells (HK-2) against uranium-induced damage. BPCBG at different doses was injected intramuscularly to male SD rats immediately after a single intraperitoneal injection of UO2(CH3COO)2. Twenty-four hours later uranium contents in urine, kidneys and femurs were measured by ICP-MS. After HK-2 cells were exposed to UO2(CH3COO)2 immediately or for 24 h followed by BPCBG treatment at different doses for another 24 or 48 h, the uranium contents in HK-2 cells were measured by ICP-MS, the cell survival was assayed by cell counting kit-8 assay, formation of micronuclei was determined by the cytokinesis-block (CB) micronucleus assay and the production of intracellular reactive oxygen species (ROS) was detected by 2',7'-dichlorofluorescin diacetate (DCFH-DA) oxidation. DTPA-CaNa3 was used as control. It was found that BPCBG at dosages of 60, 120, and 600 micromol kg(-1) resulted in 37%-61% increase in 24 h-urinary uranium excretion, and significantly decreased the amount of uranium retention in kidney and bone to 41%-31% and 86%-42% of uranium-treated group, respectively. After HK-2 cells that had been pre-treated with UO2(CH3COO)2 for 24 h were treated with the chelators for another 24 h, 55%-60% of the intracellular uranium was removed by 10-250 micromol L(-1) of BPCBG. Treatment of uranium-treated HK-2 cells with BPCBG significantly enhanced the cell survival, decreased the formation of micronuclei and inhibited the production of intracellular ROS. Although DTPA-CaNa3 markedly reduced the uranium retention in kidney of rats and HK-2 cells, its efficacy of uranium removal from body was significantly lower than that of BPCBG and it could not protect uranium-induced cell damage. It can be concluded that BPCBG effectively decorporated the uranium from UO2(CH3COO)2-treated rats and HK-2 cells, which was better than DTPA-CaNa3. It could also scavenge the uranium-induced intracellular ROS and protect against the uranium-induced cell damage. BPCBG is worth further investigation.
