BACKGROUND: Drug therapy can improve the clinical symptoms and extend the gestational age through the maternal way to treat intrahepatic cholestasis of pregnancy (ICP), however, fetal hypoxia and meconium-stained amniotic fluid can not clearly improved. OBJECTIVE: To explore the effect of replacement of amniotic fluid that contains high concentrations of bile acids by artificial amniotic fluid through amniocentesis in the rat model of ICP. DESIGN, TIME AND SETTING: Random control animal experiments were completed in the Laboratory (first-degree laboratory) of Animal Experimental Center in Chongqing Medical University from March to September 2008. MATERIALS: Forty SD pregnant rats with 15 days of pregnancy were randomly divided into intracavitary injection of S-Adenosyl-L-methionine (SAMe) (IUS), intracavitary injection of sodium chloride (IUN), intravenous injection of SAMe (IVS) and blank control (IC) groups, with 10 rats in each group. METHODS: On day 15 of pregnancy, ICP rat models were induced by daily injection of estradiol benzoate. On day 17 of pregnancy, 1 mg SAMe and 0.3 mL sodium chloride were injected into amniotic cavity of in the IUS and IUN groups through amniocentasis. Meanwhile, 30 mg SAMe were injected though tail veins in IVS group. No treatment was performed in the IC group. MAIN OUTCOME MEASURES: The meconium-stained amniotic fluid rate and the still birth rate were calculated. Total bile acid (TBA) level in amniotic fluid was measured. In addition, the expression of hypoxia-inducible factor 1 ?(HIF-1?) mRNA in the placenta of rats were examined by immunohistochemistry and reverse transcription PCR at the days 20 of pregnancy. RESULTS: The meconium-stained amniotic fluid rate in the experimental group was lower than that of the IC group (P

Stem cells transplantation has shown bright prospect in clinic myocardial infarction therapy.The researchon its mechanisms has experienced several stages,such as: cell differentiation,angiogenesis et al,which offered us a new clue for therapy.This review focuses on mechanisms of stem cells transplantation.

Images of 812 patients undergoing dual-source CT coronary angiography were analyzed retrospectively. Effectively nursing can be improved to guarantee the quality of coronary angiography and diagnosis of diseases.

To enhance interns' comprehensive ability and qualification in medical laboratory , ISO 15189 quality system that was widely accepted at home and abroad was applied in practice teaching management. First teaching experience was shared with each other, teaching competition was encouraged to improve the qualification of teaching, and then relevant academic conference and the application of scientific or new projects were also advocated to promote the construction of teaching staff. Second, the management system of the intern was improved, the rules of the management of the intern files were optimized, the train-ing and study were regularly organized, the teaching system was perfected, and the practice appraisal was standardized. Practice proved that the graduates had strong ability to work, to master the quality management of ISO 15189 elements and could solve the common problems in clinical work and at the same time they had certain scientific research thinking.

Objective To investigate the clinical distribution and the drug resistances of Pseudomonas aeruginosa (PAE) during past 3 years in the 1st Affiliated Hospital of Kunming Medical University, and to provide evidence for clinical treatment of PAE infection.Methods The isolated PAE strains from 2010 to 2012 in the 1st Affiliated Hospital of Kunming Medical University were identified and antimicrobial susceptibility tests were performed using the MIC and the KB method,and thus, the ward distribution and the drug resistance rates and the changing trend were respectively analyzed by WHONET 5.5 software, and statistically analyzed with SPSS 17.0 SOFTWARE. Results Within the three years, a total of 208 strains, 260 strains and 280 strains of Pseudomonas aeruginosa were isolated separately in 2010,2011and 2012. A total of 746 PAE strains were isolated in 3 years,in which the most common specimens were sputum (79.8%), followed by the throat swab (7.6%) and the urine (6.2%) . When it came to the ward distribution , ICU was the primary, which accounted for (32.4%), followed by the department of cadre sanatorium (27.7%), the department of respiratory medicine (12.2%) and the department of neurosurgery (6.8%) . Besides imipenem, Cefoperazone-sulbactam and aztreonam, the others were obviously in a decreasing trend in drug resistances. In 2010, 2011 and 2012, the resistances rates of imipenem were ( 65.2%) , ( 74.2%) and ( 69.5%) , respectively, the resistances rates of Cefoperazone-sulbactam were (48.0%), (48.7%) and (55.8%), and the the resistances rates of aztreonam were (72.2%), (78.2%) and (72.4%) . Amikacin,piperacillin-tazobactam,Cefoperazone-sulbactam were the most active antimicrobial agents against P.aeruginosa. Conclusions The PAE is an important source of infection, ICUs are the focus of interest for resistance monitoring and control. Antimicrobial resistance of PAE is fairly serious. Clinicians should select appropriate antibiotic therapy based on sensitivity testing.The therapeutic strategy should he adapted according to the local ecology of resistance to control the epidemic of the drug- resistance strains and hospital infection.

Objective·To explore plasma immune and inflammatory proteins that could serve as potential screening markers for Alzheimer's disease (AD).Methods·Healthy controls (n=19) and AD patients (n=19) were enrolled.Plasma samples were collected and 70 kinds of immune and inflammatory proteins were detected.The immune and inflammatory proteins associated with AD were screened by Mann-Whitney U test and partial correlation analysis.Discriminant analysis was used to develop multi-protein combined algorithm to distinguish plasma samples of AD patients from those of healthy controls.Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic efficacy for the multi-protein combined algorithm.Results·Among the 70 proteins analyzed,23 were significantly higher in AD patients (P＜0.05),among which 19 were strongly correlated with AD (P＜0.05).These 19 proteins were analyzed with Wilks' lambda stepwise analysis to develop discriminant algorithm for detecting plasma samples of AD.Finally,the discriminant algorithm established by 11 plasma immune and inflammatory proteins (EGF,GRO,MDC,MCP-1,MCP-2,MCP-4,TARC,SCF,TRAIL,CTACK,GCP-2) was found to have an optimal diagnostic efficacy (AUC=0.994).The optimal cutoff value of the algorithm was-0.609.When the optimal cutoff value was obtained,the sensitivity of the equation could reach 100％ and the specificity could reach 94.7％.Conclusion·The discriminant equation composed of the above 11 plasma immune and inflammatory proteins has the potential to assist AD screening.
