Objective To analyze the correlation between impact positions on the head and hyperextension severities of cervical spinal cord,as well as their treatment.Methods A retrospective analysis was done for 41 cases of hyperextension of cervical spinal cord without fracture-dislocation who had received management in our department from January 1999 to January 2004.All the patients had no cervical disorders before injuries.They were injured by impact mostly on the forehead,cheek or lower mandible.Their neurological findings at admission and 6-month follow-ups were assessed according to ASIA (American Spinal Injury Association) rating system.Results Of the 20 patients who were injured by impact on the forehead,four were rated in neural function as grade B,11 as grade C,and five as grade D at admission,while one as grade C,11 as grade D,and eight as grade E at 6-month follow-up.Of the 12 patients who were injured by impact on the cheek,one was rated in neural function as grade B, four as grade C,and seven as grade D at admission,while one as grade C,two as grade D,and nine as grade E at 6-mouth follow-up.Of the nine patients who were injured by impact on the lower mandible,five were rated in neural function as grade B,three as grade C,and one as grade D at admission,while two as grade B,five as grade C,and two as grade E at 6-month follow-up.The 6-month follow-ups after treatment showed that the neural function was rated below grade C in nine patients,seven of whom had been injured by impact on mandible.Two patients of grade B who showed little improvement after treatment had been injured also by impact on mandible.Conclusion Impact on the lower mandible causes mote severe hyperextension than impact on tbe cheek or forehead.Both rea- sonable non-operative and operative treatments can lead to satisfactory outcome for patients with hyperextension of cervical spinal cord but without fracture-dislocation.

Objective To explore the methods and key points of nursing care for myogenic fecal incontinence.Methods There were 65 patients with myogenic fecal incontinence in this study.All these patients had undergone sphincter reconstruction surgery.Holistic nursing and biofeedback training were provided for all these patients after surgery.Results The complications in these patients included diaper rash of 32 cases,perianal ulcer 12 cases,urinary infection 7 cases,postoperative wound infection 16 cases.After treatment and holistic care,all the diaper rash disappeared and all the peroanal ulcer healed.The urinary infection for those 7 patients were controlled.Fifteen postoperative wound infection were cured,and one recovered after intestinal fistula.Six months to two years follow-up revealed that the clinical score after treatment was significantly higher than that before treatment (1.72±0.22 vs 4.01±0.36).Conclusions Enema,holistic nursing care and rehabilitation training are important for rehabilitation of myogenic fecal incontinence.

Objective To investigate the status of the level of hope and depression with the elderly in a welfare institution in Henan Xingyang city,and to explore the relationship between them. Methods A total number of 200 elderly people were recruited conveniently from a welfare institution in Henan Xingyang city. They were investigated by General Material Questionnaire, Herth Hope Scale and Geriatric Depression Scale. Results The total score of hope and depression with the elderly in a welfare institution were (21.28±3.07) , (13.15±2.77) points respectively, the depression detection rate was 82.38%(159/193);the level of hope was negatively related with depression (r=-0.447,P<0.01). Conclusions The hope of the elderly in welfare institution is not optimistic,and the depression detection rate is high,the level of hope is positively related with their depression,so we should take effective measures to improve their mental health according to the emotional state to give emotional care and improve the level of their hope.

Objective: The sustained release curcumin solid lipid nanoparticles (Cur-SLN) and long circulating solid lipid nanoparticles (LSLN) were prepared, and the physicochemical properties of the two nanoparticles were investigated. Methods: Cur-SLN was prepared by emulsification ultrasonic method, and then the entrapment efficiency and drug loading of Cur-SLN prepared under the optimal formulation were determined. Cur-LSLN was prepared by back-extrapolation method, and the physicochemical properties of Cur-SLN and Cur-LSLN were evaluated by entrapment efficiency, drug loading, particle size, and Zeta potential; DSC was used to analyze, in vitro release characteristics and the transmission electron microscope (TEM) was used to observe particle appearance. Results: Based on the optimal conditions, TEM showed that the appearance of Cur-SLN and Cur-LSLN were spherical or nearly spherical, the entrapment efficiency respectively were (89.15 ± 0.66)% and (92.97 ± 0.27)%, drug loading were (1.72 ± 0.08)% and (1.98 ± 0.08)%, average diameters of particles were (144.5 ± 4.1) nm and (155.0 ± 2.6) nm, and the mean Zeta potential were (-23.6 ± 0.2) mV and (-47.8 ± 1.8) mV. Through DSC detection, it can be determined that Cur in nanoparticles had been transformed into amorphous state. In vitro release test showed that the drug release of the two preparations was divided into two stages: burst release phase and sustained released stage, the release rate was fast in 12 h, and the cumulative release of Cur-SLN in 96 h was 86.63%, and Cur-LSLN was 76.98%, so Cur-LSLN showed better sustained-release effect. Conclusion: Cur-SLN and Cur-LSLN can be successfully prepared by emulsification ultrasonic method, and PEG modified nanoparticles have better sustained-release properties and prolong the time of the presence of drug in vivo, providing reference for the development of targeted drugs.

The standardization of compound nomenclature is of vital importance. The principles of standardization include scientificity, systematization, monosemy, openness, and back-translatability. The standardized compound names should also be cross-translatable from roots of the words and easy to remember. The article indexed 592 new active natural compounds, referencing 222 papers from 11 leading foreign periodicals and four domestic journals. The names of new compounds in the paper may be controversial, but the nomenclature was complied with the above principles of standardization.

SWNTs are a mixture of 1/3 metallic SWNTs (m-SWNTs) and 2/3 semiconducting SWNTs (s-SWNTs). It is desirable to separate the metallic SWNTs from the semi-conducting ones. In this study m-SWNTs was separated by using a poly[(m-phenylenevinylene)-alt-(p-phenylenevinylene)] (PmPV) derivative and used as photo-thermal media instead of SWNTs. The separation effects of m-SWNTs were evaluated by Raman spectra, molecular modeling and TEM images. The effects of m-SWNTs on MCF-7 cell proliferation and apoptosis were evaluated with MTT assay and flow cytometry, respectively. m-SWNTs were separated with high purity. A strong inhibition of MCF-7 cell growth was observed with the m-SWNTs under near-infrared (NIR) light irradiation. Our results will be helpful for the potential applications of m-SWNTs in clinical photothermal cancer therapy.

Objective To compare the efficacy of tamsulosin and tolterodine for the adjunctive expulsive therapy in patients with lower ureteral stones.Methods A total of 160 patients with lower ureteral stones(4-10 mm)were included in the study.The patients were divided into 4 groups by block randomization.Group Ⅰ patients received tamsulosin 0.4 mg/d;group Ⅱpatients received tamsulosin 0.4 mg/d plus tolterodine 2 mg(twice a day);group Ⅲ patients received toherodine 2 mg(twice a day);and group Ⅳpatients served as controls.All patients were observed for 2 weeks.Remits The stone expulsion rate of group Ⅰ,Ⅱ,Ⅲ,Ⅳ was 76.9%(30/39),70.0%(28/40),46.2%(18/39)and 42.1%(16/38),respectively.The stone expulsion rate in group ⅠandⅡwas,higher than that in group Ⅲand Ⅳ(P＜0.05).The expulsion time of group Ⅰ,Ⅱ,Ⅲ,Ⅳ was(5.3±2.5),(6.4±2.2),(10.7±1.8),(12.8±3.4)d,respectively,with significant differences between group Ⅰ,Ⅱ andⅢ,Ⅳ,between groupⅢand Ⅳ(P＜0.05).Almost all of the patients tolerated the expulsive therapy and only 4 patients withdrew from treatment.No obvious side effect occurred.Conclusion The use of tamsulosin for the expulsion of lower ureteral stones is effective and safe;however,the use of tolteredine provides no additional advantages.
