Objectives: To find out influencing factors of quality of life(QOL) of staffs in Centers for Disease Prevention and Control(CDC),whose results would be taken as theoretical evidence for government policy-makers to work out strategy of health human resources.Methods: The WHO Quality of Life Brief Scale(WHOQOL-BREF) was employed as the assessing tool for staffs of CDC who were in a city and its neighborhood counties.Each subject was asked to complete a spot self-assessment.Results: There is no significant difference of QOL of staffs between city and neighborhood county.Working at different departments was one of the influencing factors on psychological and social domains.Harmonious family relationship,good appetite,agreement to work competition,and confidence in working institutes were influencing factors to the total score of QOL.Conclusions: Scores of QOL of CDC staffs were relatively low with various influencing factors.It is necessary for leaders of related departments to take countermeasures to improve the QOL of CDC staffs.

The appearance and development of laser technology had made Raman spectroscopy one of the most attractive research fields in analysis using laser.Raman spectroscopy had been widely used in the analysis of material components and structure.In this review,recent advances of Raman spectroscopy on human blood were summarized,which including the basic research on red cells,white cells,platelets and the serum concentrations of various substances by Raman spectroscopy.The rewiew also intruduces the Raman spectroscopy on early diagnosis for cancer,diagnosis for blood diseases,and its future development.

To train the clinical ideation of students majoring in medicine is one of the goals of medical education. Applying the integrated teaching methods to the physiology theory education is helpful to cultivating students′abilities to think and practice the clinical ideation and application,inspiring their interests in study,evoking their ideation and enhancing their abilities to learn initiatively and solving problem independently.

The chemokine fractalkine primarily involves in chemotaxis,adherence and inflammation.Recently it has been discovered owning the ability of inhibiting cell death in neurons and glial cells,as well as protecting central nervous system from toxic damage.Fractalkine reduces the toxicity to neurons and glial cells mediated by excessive Fas L,glutamate(Glu) or lipopolysaccharide(LPS).In vivo neutralization of endogenous brain fractalkine signal pathway increases inflammatory cytokines secretion and neuronal cell death induced by LPS.Fractalkine may achieve its neuroprotective property through influencing expression of pro-apoptotic and anti-apoptotic proteins,intracellular Ca2+ level and inflammatory cytokines secretion via protein kinase B(PKB)/Akt and extracellular signal-regulated kinase(ERK)/MAPK pathways.

Objective To investigate the changes and its significance of serum content of soluble CD40L(sCD40L) and C-reactive protein(CRP) in patients with acute cerebral infarction(ACI).Methods The content of serum sCD40L and CRP in 40 patients with ACI and 30 normal controls were measured by enzyme-linked immuno-sorbent assay and immunonphelometry.The content of serum sCD40L and CRP were compared in the patients of different pathogenetic condition and infarction size.The correlation between sCD40L and CRP and pathogenetic condition and infarction size were analysised.Results The contents of serum sCD40L and CRP in ACI group were significantly higher than normal control group(all P

Objective A meta-analysis was conducted to figure out the effects of anesthetic methods on postoperative myocardial infarction in noncardiac surgery patients.Methods We searched PubMed, Embase, Ovid, Cochrane Library, Google scholar, CNKI, Wang-fang data and VIP Database (by September 2016) to identify relevant studies that focused on the effect of intrathecal blockade on postoperative myocardial infarction and mortality in non-cardiac surgery.Meta-analysis was performed using software of RevMan 5.3.Results A total of 21 859 patients from 10 RCTs were enrolled.The meta-analysis showed that there were no differences in myocardial infarction within 7 postoperative days (OR=0.44, 95%CI 0.13-1.46, P=0.18) or 30 days (OR=1.49, 95%CI 0.89-2.49, P=0.13) and all-cause mortality (OR=1.26, 95%CI 0.84-1.88, P=0.26) between epidural anesthesia combined with general anesthesia and general anesthesia.Furthermore, there were no differences in myocardial infarction within postoperative 7 days (OR=1.14, 95%CI 0.31-4.17, P=0.84) and all-cause mortality within postoperative 30 days (OR=0.88, 95%CI 0.43-1.79, P=0.73) between spinal anesthesia alone and general anesthesia alone.Conclusion Intrathecal blockade cannot affect the incidence of myocardial infarction and mortality in high-risk cardiac patients undergoing intermediate or high-risk non-cardiac surgery.

OBJECTIVE:To establish an HPLC method for the determination of related substances in Donepezil hydrochloride tablets.METHODS:The separation was performed on AlltimaTM C18 column with mobile phase consisted of 0.01 mol?L-1 dipotassium hydrogen phosphate(3% triethylamine,pH=4.3)-methanol(60 :40) and flow rate of 1.0 mL?min-1.The detection wavelength was set at 271 nm and the column temperature was maintained at 35 ℃.The content of related substance was calculated by self-control with main component.RESULTS:Related substances were completely separated from the main constituent and the impurities were separated well from each other.The determination limit was 0.05 ng and the contents of related substances were 0.42%.CONCLUSION:The method is specific,sensitive and reproducible for the determination of related substances in Donepezil hydrochloride tablets.

The authors used a microvascular corrosion cast/scanning electron microscopy (SEM) technique to study the microvascular bed of the muscles of the medial pterygoid and masseter in two normal babies. The cast were prepared by perfusing the microvascular vessels with methyl methacrylate. Under SEM, the patterns of branches of the arteriole are: 1. tree like ramifications; 2. symmetrical branching; 3. fine plexiform branching. Moreover, the casts of arterial and venous vessels showed on their surfaces the typical imprint of the endothelial lining. Therefore, the venous vessels could be easily identified by the round nuclei of the endothelial cells of the venous vessels. On the other side, arteries and arterioles displayed spindle shaped nuclear imprints, oriented along the direction of the vessel. The morphological and functional characterization of the imprint of the precapillary sphincter and the two-grade anastomoses of the arcade arteries. The diameter of the capillary casts (mean?SE) was 5.6?1.9?m. Two or three capillaries join together to form a postcapillary venules, sometimes a single capillary reaches a major venous trunk was observed. These structural features were considered to play an important physiological role in the microcirculation in skeletal muscle.

Objective The purpose of this study was to observe the feature of tunnel enlargement after anterior cruciate ligament reconstructions and to investigate the influencing factors and the relationship between bone tunnel enlargement and clinical outcome. Methods There were 103 patients who accepted anterior cruciate ligament reconstructions with autogenous hamstring tendons for follow-up. Magnetic resonance imaging(MRI) offered the possibility of visualizing the bone tunnels from 12 to 18 months after surgery. The width was measured for tibial and femoral tunnel and compared to initial width. The tunnel size was graded to 4 grade depending on the increased width: grade 0(
