Chinese Journal of Nosocomiology 2005;0(11):-
OBJECTIVE To provide more evidence for hospital infection control.METHODS To(analyze) the clinical records of the hospital-acquired pneumonia(HAP) of senile patients in department of(neurology) during Jan 2004 to Dec 2005 retrospectively.RESULTS There were 109 person-times(145 cases) senile(patients) with hospital(infection) during the two years.From them 77 cases were hospital-acquired infection,32 cases were ventilator-(associated) pneumonia(VAP),the infection rate was 22.1%.CONCLUSIONS The infection of HAP in department of neurology may induce by several factors.The key point to control HAP is prospective monitoring hospital(infection) in time,and taking effective measures to prevent the hospital infection on the basis of treatment the(underlying) disease.

Chinese Journal of Analytical Chemistry 2001;29(6):699-702
Capillary gas chromatographic column 1 (7.5% W/W,3 5×0. 35mm i.d.) and column 2 (9.2% W/W,35×0.30mm i.d.) using butylammonium 4-to unesulfonate as stationary phase were prepared by the method of dynamic coating with mercury plug, and the solvent used was mixture of acetone and methanol (2 ∶1 V/V). The results showed that the column had good chromatograpic pro perties, especially to strong polar compound, such as carboxylic acids and acoho ls could be separated well.

Chinese Journal of Geriatrics 2009;28(10):870-872
Objective To investigate the clinical characteristics of nosocomial infections in senile inpatients(≥75 years old) and to propose the control strategy according to the analysis. Methods A total of 2675 senile inpatients(≥75 years old) from 2007 to 2008 were prospectively evaluated and retrospectively reviewed. The infection incidence rate, infection fatality rate, average length of stay in hospitals, location of infections, main pathogenic bacteria and common protopathy were analyzed. Results Among 2675 senile inpatients, 222 senile inpatients suffered from nosocomial infection. Among all age groups in this hospital during the same period, the infection incidence rate and the infection fatality rate were higher in the senile group than in the general group(8.3% vs. 1.9%, 0.8% vs. 0.1%,both P<0.01). The average length of stay in our hospital was 54.0 days. The lower respiratory tract infections were most common, and the urinary system infections, and the blood infections. Gram-negative bacteria was the major source of nosocomial infection(47.0%, 110/234), while infection rate of Gram-positive bacteria was 32.9% (77/234) and fungus was 20.1% (47/234). The cerebral vascular disease was the most common protopathy, then malignant tumor was in 45 cases (20.3%), kidney disease was in 31 cases(14.0%), cardiac disease was in 29 cases(13.1%) and respiratory disease was in 21 cases(9.5%). Conclusions There are higher infection incidence rate, higher infection fatality rates,longer length of stay in hospitals in senile inpatients(≥75 years old). The lower respiratory tract infections were most common and Gram-negative bacteria was the major source of nosocomial infection. We should adopt active management to control the nosocomial infections.

OBJECTIVE: To seek the bionic material myocardial extracellular matrix in the myocardial tissue engineering for the cultured myocardial cells and to provide a reliable scaffold.METHODS: A computer-based online search of CNKI and PubMed database to search articles published between January 1996 and August 2007 on scaffold material of tissue engineering.RESULTS: Natural biological scaffold materials with good biocompatibility and mechanical properties are ideal choice in the cardiac tissue engineering rapid prototyping technology. Natural biological materials such as collagen, chitosan have poor mechanical properties and plasticity, but good biocompatibility, which can be used for rapid prototyping of cardiac stents. The scaffolds which are prepared by the technology such as three-dimensional printing, laser sintering, three-dimensional pressing,selective laser sintering rapid prototyping technology on have the advantages such as high porosity, high surface area volume ratio,completely transparent among the holes, controllable macro-shape, porosity, and independent control of aperture.CONCLUSION: Through the use of dispersion/accumulation forming principle, surface modification of traditional biological materials in cardiac tissue engineering using computers and other high-tech nano-polymer technology is expected to provide ideal myocardial scaffolds.

Objective To evaluate the influence of SP600125,a selective c-Jun N-terminal kinase (JNK) inhibitor,on the levels of serum total bile salt (TBA) and Bsep,Ntcp expression in the hepatic tissue of rats with ethinylestradiol induced intrahepatic cholestasis.Methods Rats pregnant for 15days were administered the subcutaneous injection of 17- b -estradiol propylene ( EE ) to modulate the ICP animal models,and be SP600125 to intervene.Testing the level of serum TBA and the expression of c-Jun,Bsep,Ntcp in the hepalatic tissue.Results The average gray values of c-Jun in the group of ICP models were significantly lower than the normal control group ( 101.05 ± 5.20 vs 118.99 ± 5.95,P < 0.05 ).After the intervention of SP600125,comparing with the group of ICP models,the expression of Bsep,Ntcp in the group of SP600125 intervention were significantly higher,and this change in the high dose of SP600125 intervention group was more obvious ( low dose intervention group Bsep:0.452 ±0.031 vs 0.291 ±0.043,Ntcp:0.462 ± 0.015 vs 0.285 ± 0.021,P < 0.05 ; high dose intervention group Bsep:0.568 ± 0.038 vs 0.291 ±0.043,Ntcp:0.605±0.020 vs 0.285 ±0.021,P <0.05),while the level of TBA in the serum was significantly lower.Conclusions Treatment with SP600125 can down-regulate the level of c-Jun/AP-1,and it may participate in the lower expression of Bsep、Ntcp in the ICP rats which were induced by 17-bestradiol.

Objective To analyze the clinical characteristics of dopa-responsive dystonia (DRD). Methods The clinical characteristics and the causes of misdiagnosis in 15 patients with DRD were reviewed retrospectively.Results 4 male and 11 female patients were investigated in this study. The age at DRD onset was from 3~25 years old,the average age was 11.7 years old.The courses ranged from 2 to 29 years and the average was 12.1 years. The symptoms in female patients often aggravated during gravidity and delivery. Main clinical features included gait irregularity, postural instability and tremor, with marked diurnal fluctuation. The disease may be misdiagnosed as cerebral palsy, idiopathic torsion dystonia, essential tremor, parkinson's disease, neurosis and so on. All the patients in this study improved obviously in 2 weeks after therapy with low dose of Madopar, and recovered in 2~4 years of follow up.Conclusions Clinical diversity and diurnal fluctuation are the characteristics of DRD. Early trial treatment with low dose of Levodopa should be highly recommended for the generalized dystonia in children and untypical adults.
