Objective To explore current status of health-related productivity loss and its risk factors among nurses.Methods Stanford presenteeism scale (SPS-6) and self-designed questionnaire were used to investigate current status of health-related productivity loss and its risk factors among 1122 nurses working in a tertiary hospital in Changchun city.Results Compared with hired nurses,age and work seniority of permanent nurses were significantly higher(Z =-19.49,-19.28 ;P <0.05).The average score of SPS-6 of all the participants was 20.05 ± 4.37.The score of SPS-6 of married nurses was significantly lower than other nurses (Z =-3.52,P < 0.05) ; and the score of SPS-6 of nurses less than 30 years old was significantly higher than those above 30 years old (Z =-2.49,P < 0.05).There were no significant differences between the SPS-6 score of education degree and department.(Z =-1.37,x2 =0.58 ; P >0.05).The result of GLM showed that employment status and work seniority were independent risk factors of health-related productivity loss among nurses.The scores of SPS-6 of permanent nurses was significantly lower than hired nursed (x2 =4.48,P < 0.05),and those who had worked for less than 3 years showed significantly higher score of SPS-6 than those who had worked longer (x2 =12.89,P < 0.05).Conclusions Health-related productivity loss do exist among nurses.Improving health management may help to reduce this loss of productivity.
2.Application of "stepped-wedge design" methodology in randomized controlled trials
Chinese Journal of Epidemiology 2010;31(1):92-95
In this article, two research cases are employed to show the rationale of the stepped-wedge design, under what situations that such a design is desirable, and how it can be implemented. Stepped-wedge design seems to suit to randomized controlled trials in which the entire study population will receive intervention programs as they would "provide more advantages than harm". When intervention can not be given to all the targets simultaneously due to limited resources, this design is particularly useful. The stepped-wedge design is also relevant when there is a hope to detect or control the time trend effect on the effectiveness of the intervention strategy. On the other hand, however, this design requires longer trial duration and presents a number of statistical challenges. Hence, careful planning and monitoring are essential to ensure that a robust evaluation is undertaken.

OBJECTIVETo explore the effects of arecoline on hepatic insulin resistance in type 2 diabetes rats and to elucidate its possible mechanism.
METHODSForty five Wistar rats were fed with high fructose diet for 12 weeks to induce type 2 diabetic rat model. rats were randomly divided into 5 groups (n = 8): control group, model group and model group were treated with different dose (0, 0.5, 1, 5 mg/kg) of arecoline. After 4 weeks, the fasting blood glucose, blood lipid and insulin level measured , mRNA expression of liver constitutive androstane receptor (CAR), pregnane X receptor (PXR), glucose-6-phosphatase (G6Pase), phosphoenolpyruvate carboxykinase (PEPCK), interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) were detected by reverse transcription polymerase chain reaction (RT-PCR), the protein expression of p-AKT and glucose transporter4 (GLUT4) were detected by Western blot.
RESULTS1.5 mg/kg arecoline could significantly decrease the level of fasting blood glucose, blood lipid, blood insulin level and liver G6Pase, PEPCK, IL-6, TNF-alpha mRNA level in type 2 diabetes rats. 1.5 mg/kg arecoline also could significantly increase CAR, PXR mRNA level and p-AKT and GLUT4 protein expression.
CONCLUSIONArecoline improved hepatic insulin resistance in type 2 diabetes rats by increasing the mRNA levels of CAR and PXR leading to the creased glucose metabolism and inflammation related genes expression.

OBJECTIVETo observe the effect of Huatuo Zaizao extractum (HTZZ) on focal cerebral ischemia/reperfusion (I/R) neurogenesis in rats induced by middle cerebral artery occlusion (MCAO) and its mechanism.
METHODTotally 55 healthy adult male Sprague-Dawley rats were divided into the sham operation group, the MCAO model group and HTZZ high, middle and low dose groups (5, 2.5, 1.25 g x kg(-1)), with 11 rats in each group, and orally administered with drugs. The focal cerebral ischemia model was established by performing a middle cerebral artery occlusion (MCAO, 90 min) followed by a seven-day reperfusion (once a day). The neurogenesis and expressions of extracellular signal-regulated kinase (ERK) and cAMP response element binding protein (CREB) were detected by the immunofluorescent staining. The enzyme linked immunosorbent assay (ELISA) was adopted to determine the vascular endothelial growth factor (VEGF) and brain-derived neurotrophic factor (BDNF).
RESULTMCAO (90 min) followed by a seven-day reperfusion resulted in the significant increase in the number of penumbra cortex newborn neurons (BrdU(+) -NeuN(+)), which was accompanied by the growth of ERK and CREB phosphorylation and VEGF and BDNF levels. HTZZ could promote the generation of newborn neurons (BrdU(+)-NeuN(+)) and the ERK and CREB phosphorylation and increase VEGF and BDNF levels at the ischemic side.
CONCLUSIONHTZZ could promote the neurogenesis, which may be the interventional targets of effective traditional Chinese medicine Huatuo Zaizao extractum in promoting the self-repair function of the cerebral ischemic areas.

OBJECTIVETo evaluate the reporting and transferring system for tuberculosis (TB) patients carried out by city General Hospitals & township clinics in the last 10 years in China.
METHODSSystematic review and Meta-analysis were carried out.
RESULTSAfter 5 years of follow-up on the outcomes of intervention, it was found that both the rates of newly registered smear positivity and the new case registration on smear positivity had significantly been increasing during the last five years and the scale of increase was growing annually during the first three years. However, the scale of increase started to decline on the fourth year. The combined RR on the failure of transfer rate was 0.36 (95% CI: 0.25 - 0.53).
CONCLUSIONThe integrated outcomes showed that the ongoing reporting and transferring system in general hospital was benefit for TB case detection.

OBJECTIVETo analyze the clinical features of patients with newly diagnosed myeloma bone disease (MBD).
METHODClinical features of MBD in two hundred and five patients with newly diagnosed multiple myeloma (MM) were analyzed retrospectively. The relationship between outcome of different grades of MBD patients and their prognosis was compared.
RESULTS(1) Among the 205 patients, one hundred and fifty (72.7%) had bone pain as the first symptom. (2) According to X-ray evaluation, there were 23 (11.3%) of grade 0, 14 (6.9%) grade 1, 23 (11.3%) of grade 2, 68 (33.3%) grade 3 and 76 (37.2%) grade 4. (3) Patients with grade2-4 MBD had significantly higher ECOG performance score, marrow plasmacytes, marrow CD138(+) CD38(+) cell percentage and serum IL-6 level than those with grade 0 - 1 did (P < 0.05). Patients with grade 4 MBD presented with hypocalcemia (P < 0.05) more often than those with grades 0 - 3 diseases did. (4) There was no significant difference in response to initial induction chemotherapy among the five groups (P = 0.642). (5) Univariate analysis demonstrated that the time to progression (TTP) in grade 2 - 4 MBD groups was significantly shorter than that in grade 0 - 1 groups (P = 0.029). (6) Multivariable COX analysis did not indicate lytic bone changes was a independent prognostic factor for OS and TTP.
CONCLUSIONThere is a rather high incidence of MBD in MM patients in China. Patients with extensive X-ray bone lesions have more severe hematologic parameters than those without bone lesions did, and severe bone lesions is an important adverse prognostic factor for TTP.
