Objective To observe the effect of fluid resuscitation on hemodynamies and oxygen in severe trauma patients. Methods Parameters of hemodynamic and oxygen metabolism in different fluid volume resuscita-tion in 24 severe trauma patients who were injured on abdominal were measured. Results By fluid resuscitation, as the systolic blood pressure was raised from 80～90 mm Hg(1 mm Hg=0.133 kPa) to 100～120 mm Hg,cardiac in-dex rose from (2.0±0.5 ) L/(min·m2) to (3.2±0.6) L/(min·m2) (P<0.05), systemic vascular resistance index rose from (1857.6±750.2) dyn·s/(cm5·m2) to (3741.5±862.1) dyn·s,/(cm5·m2) significantly (P<0.05). Meanwhile, oxygen delivery index rose from (301.1±74.1) ml/(min·m2) to (554.1±80.0) mL/(min·m2) (P<0.05), and oxygen consumption index also rose (99.7±51.4) mL/( min·m2) to (147.2± 60.1) mL/(min·m2) remarkably (P<0.05), the rate of oxygen expenditure decreased from (33.1±9.1) % to (26.6±8.0) % significantly (P<0.05). Conclusion Large volume resuscitation maybe benefit to the improve-ment of hemodynamics and oxygen metabolism in the emergency resuscitation.

BACKGROUND: So far there is a lack of reliable biomedical evidence about the effects of three-dimensional y (3D) printed porous β-tricalcium phosphate (β-TCP) scaffold loading poly(lactic-co-glycolic acid) (PLGA)/anti-tuberculosis drug control-release microspheres on the growth and proliferation of cel s, especial y osteoblasts. OBJECTIVE: To construct porous β-TCP scaffold loading PLGA/anti-tuberculosis drug control-release microspheres by 3D printing technology and to detect its cytotoxicity. METHODS: Twenty porous β-TCP scaffolds whose aperture was 400 μm were prepared by 3D printing technology. Ten of these scaffolds were randomly selected for loading PLGA/anti-tuberculosis drug control-release microspheres, and the others were without any drugs. Then the extracts from two groups were cultured with osteoblasts for 72 hours. Afterwards, cel morphology was observed by inverted phase contrast microscope, and the absorbance value was detected using cel counting kit-8 assay. Besides, the relative growth rate of osteoblasts was calculated to evaluate the cytotoxicity of the scaffold. RESULTS AND CONCLUSION: The drug-loaded scaffold exhibited with moderate size, regular structure and uniform pores. Within 72 hours of culture in the extracts from the drug-loaded scaffold, elongated or fusiform osteoblasts appeared, with less karyopycnosis. Moreover, the drug-loaded scaffold showed slight cytotoxicity, which was classified as grade 1. In conclusion, the 3D-pinted porous β-TCP scaffold loading PLGA/anti-tuberculosis drug control-release microspheres exhibits no obvious cytotoxicity.

The paper gives an account of the four systems that are currently used for evaluating hospital quality in America, viz. America's Best Hospitals, Solucient 100 Top Hospitals, International Quality Indicator Project, and the Joint Commission on Accreditation of Healthcare Organizations. The "America's Best Hospitals" methodology takes into account three factors, infrastructure, process and outcome. Hospitals are first ranked in specialties, then the index of hospital quality is calculated by means of weighted indexes, and after that the best hospitals are selected according to the specialty rankings and the number of the hospitals. The "Solucient 100 Top Hospitals" methodology selects 100 top hospitals among hospitals of the same size on the basis of hospital quality and safety indexes. The evaluation indexes include eight items, such as index of risk-adjusted mortality rates, index of complications, and disease severity-adjusted average length of hospital stay. The methodologies of "International Quality Indicator Project" and "the Joint Commission on Accreditation of Healthcare Organizations" are used in many countries to evaluate clinical efficiency and enjoy high reputation in monitoring and promoting medical quality.

Objective To study the clinical manifestation of preeclampsia complicated with placental abrup-tion and its treatment measures.Methods 160 patients with placenta abruption were selected,and the patients with preeclampsia complicated with placental abruption were selected as the study group(70 cases),and the patients with non preeclampsia complicated with placental abruption were selected as the control group(90 cases).The clinical manifestations,infant outcome and treatment measures of the two groups were compared.Results When the disease attack of the study group often accompanied with vaginal bleeding,but few had symptoms of abdominal pain,the main symptoms of the control group was vaginal bleeding and abdominal pain.The occurrence rate of abdominal pain of the two groups had statistically significant difference(4.3%vs 92.2%,χ2 =11.032,P<0.05);The placental abruption of the study group wasⅡdegree andⅢdegree(81.4%)while the control group wasⅠdegree(62.2%),with signif-icant difference between the two groups(χ2 =10.973,P<0.05);The incidence of fetal distress of the two groups had no statistical significant difference(95.7% vs 93.3%,P>0.05);The incidence of neonatal asphyxia of the two groups had no significant difference(56.6%vs 55.6%,P>0.05);The perinatal mortality of the two groups had sta-tistically significant difference(31.7%vs 11.1%,P<0.05);1 case of patient′s cervix was fully opened in the study group when at 28 weeks gestational,and been given the vaginal delivery,all others were given operation to terminate the pregnancy,3 cases in the control group used the vaginal delivery,there was no significant differences between the two groups(P>0.05).Conclusion The clinical manifestation of preeclampsia was not typical,with a greater harm to the fetus and perinatal infant,operation to termination of pregnancy is the main method for treatment of preeclamp-sia complicated with placenta abruption.

Objective To investigate the clinical effects of fluoxetine combined with small doses of aripiprazole in treatment of post -stroke depression and the influence on the recovery of neurological function. Methods 74 patients with post stroke depression were randomly divided into the two groups,all patients were given routine comprehensive treatment,the control group treated with fluoxetine,while the observation group was treated with fluoxetine combined with small doses of aripiprazole,clinical curative effect,neurological deficits and activities of daily living of the two groups were compared.Results The total effective rate of the observation group was 94.59%,which was significantly higher than 78.38% of the control group (χ2 =9.78,P<0.05);NIHSS scores of the observation group at the end of 4 week and 8 week of treatment were (10.85 ±1.22)and (6.03 ±0.78),which significantly reduced than that of the control group(t=6.18,6.62,all P<0.05 );Barthel index of the observation at the end of 4 weeks and 8 weeks of treatment were (49.56 ±4.68)and (67.43 ±4.75),which significantly increased than that of the control group(t=6.63,7.00,all P<0.05);The incidence of adverse reactions of the two groups had no signif-icantly different(χ2 =2.38,P>0.05).Conclusion Fluoxetine combined with small dose of aripiprazole has an ex-act effect in the treatment of post stroke depression,with high security.

Aim To investigate the expression pattern of secretory clusterin ( sCLU) in lung tissues and plas-ma of rats with pulmonary arterial hypertension ( PAH) induced by monocrotaline ( MCT ) . Methods Thirty male SD rats were randomly divided into control group ( n=6 ) and MCT group ( n=24 ) , and were intraper-itoneally injected 60 mg·kg-1 MCT for MCT group or equal volume normal saline for control group. Real time PCR and Western blot were performed to investi-gate the expression pattern of sCLU mRNA and protein in rat lungs 1 ( n=6 ) , 2 ( n=6 ) , 3 ( n=6 ) and 4 (n=6) weeks after MCT injection, respectively. Im-munohitochemistry was performed to determine the lo-calization of sCLU in rat lungs. Enzyme linked immu-nosorbent assay was performed to detect the concentra-tion of sCLU in rat plasma. Results Expression of
sCLU mRNA and protein elevated significantly in time-dependent manners in rat lungs of MCT group, and sCLU mainly localized in the cytoplasma and extracel-lular matrix of cells in pulmonary arterioles. Further-more, sCLU plasma levels were significantly elevated with the progression of PAH and had positive correla-tions with pulmonary hemodynamic indices and right ventricular hypertrophic index. Conclusion sCLU was significantly elevated in MCT induced PAH rat lungs and plasma, and it may participate in the pulmo-nary vascular remodeling process. Moreover, plasma sCLU may be a potential biomarker for PAH.
