Objective To learn the current status of job burnout and influencing factors for nurses from infectious disease hospital.Methods The Chinese version MBI -HSS was used to survey 218 nurses from infectious disease hospital,and linear regression was used to analyze the influencing facters of job burnout.Results A total of 210 questionairs were cocleted.The incidence of severe occupational job burnout was 22.38%,and the score of emotional exhaustion (EE), depersonalization (DP),personal accomplishment (PA)was(22.82 ±9.98),(6.48 ±5.20),and (35.20 ±8.82), respectively.Regression analysis demonstrated that the main influencing factors were entering the isolation ward, opportunity for infectious diseases ,disinfection damage,fear of occupational exposure and concern on family infection(P <0.05).Conclusion The status of job burnout of nurses in infectious disease hospital is not optimistic.There is a positive relationship with the working environment,occupational exposure.Managers need to explore an effective way to ease the job burnout of nurses,and to stabilize the nursing team.

OBJECTIVETo investigate the influence of isoliensinine (IL) on CYP3A enzyme activity.

METHODSA mixture metabolic system of liver microsome enzymes in vitro was developed. A HPLC method to test the metabolic activity of CYP3A was established with testosterone as a probe. The activities of CYP3A enzymes were measured with different IL concentrations and incubation time with testosterone.

RESULTSIn mixture metabolic system of liver microsome enzymes, the best incubation concentration of testosterone was 200 μmol/L, the best incubation time was 210 min, in this condition the IC₅₀ of IL for CYP3A inhibition was >1 000 μmol/L.

CONCLUSIONNo significant interaction between IL and CYP3A is detected, which indicates that IL might be used with CYP 3A enzyme substrates.

This article mainly summarise the results of the chemical compositions and their pharmacological activities of Arnebiae Radix since 1966. The chemistry components isolated from Arnebiae Radix are mainly naphthoquinone, monoterpene phenol and quinone, phenolic acids and their salts, alkaloids, aliphatic and esters. Pharmacological results showed that the chemical compositions and the extracts of Arnebiae Radix have antibacterial, anti-inflammatory, anti-viral, hepatoprotection, antioxidant, anti-tumor and immune function and other activities. This article hopefully to provide a reference for further research, development and utilization of Arnebiae Radix.

To investigate the influence of stainless steel(SS)and titanium oxide(Ti-O)thin films on the cytokine released by en-dothelial cells.Ti-O films were prepared by unbalanced magnetron sputtering deposition system(UBMS).Human umbilical vein en-dothelial cells(HUVECS)were isolated and seeded on SS and Ti-O materials.Nitride oxide (NO)and monocytc chemotactic protein one(MCP-1)concentrations were determined in the supematants with enzyme linked immunosorbent assay(ELISA)at 1,3 and 5 days after culture,and the morphology of the cells was observed using scanning electron microscopy(SEM).The results showed that the similar amount of HUVECs was presented in SS and Ti-O culture.But HUVEC had better morphology on Ti-O film than SS.The NO and MCP.1 test also showed that HUVECs on Ti-O film had a better bio-function than SS.It is concluded that Ti-O film as a biomaterial may have a better endothlieal compatibility,which can be used to enhance the endothelialization.

Objective To find out the iodine nutritional status and thyroid function of pregnant and lactating women in the urban areas of Wuwei City of Gansu Province,and to provide a scientific basis for iodine supplementation.Methods Blood and urine samples of pregnant (52 persons) and lactating women (59 persons) were collected in 2009.Urinary iodine content was measured with arsenic cerium catalytic spectrophotometric.Serum free three triiodothyronine(FT3),free thyroid hormone(FT4),triiodo thyronine(TT3),serum total thyroxine (TT4) and thyroid-stimulating hormone (TSH) were detected with direct chemiluminescence immunoassay.Results The medians urinary iodine of pregnant and lactating women were 274.68,217.88 μg/L.The rates of low urinary iodine (pregnant women below 150 μg/L,lactating women lower than 100 μg/L) were 9.62％ (5/52) and 6.78％ (4/59).Serum TT3,TT4 levels in pregnant women[(2.48 ± 0.59),(132.18 ± 33.36)nmoL/L] were higher than that in the lactating women[(2.16 ± 0.49),(108.79 ± 28.36)nmol/L,t =-3.123,-3.971,all P ＜ 0.05].Thyroid dysfunction incidence rates of pregnant and lactating women were 17.31％ (9/52) and 8.47％ (5/59).Thyroid dysfunction was mostly subclinical hypothyroidism.Conclusions Overall iodine nutrition of pregnant and lactating women is in good condition,some individuals have the trend of hypothyroidism.It is necessary to carry out routine monitoring of urinary iodine and thyroid function.

OBJECTIVETo study the effects of L.F04, the active fraction of Lycopus lucidus, on erythrocytes rheological property so as to investigate its mechanism in promoting blood circulation and removing blood stasis.

METHODThe effects of L.F04 (used for treatment for 10 days in different dosages) on deformability, aggregation and membrane liquidity of erythrocytes (MLE) as well as whole blood apparent viscosity (eta(b)) were examined on the basis of rat model of blood-stasis syndrome induced by venous injection of high molecular weight dextran.

RESULTAs compared with the normal control group, the model group's RBC deformability and MLE were lower, and the aggregation of erythrocytes and eta(b) were higher. Compared with the model group, both L.F04 0.612 g/kg and 0.306 g/kg showed significant effect in improving deformability and inhibiting aggregation of red blood cells (RBC) and reducing blood viscosity. The trend of improving MLE was also shown.

CONCLUSIONL.F04 could significantly improve the abnormal rheological property of erythrocytes.

The traditional treatment of scoliosis is mainly based on open surgeries that use the anterior approach, the posterior approach, or both. These surgical procedures often lead to complications including massive blood loss, infections, and pain of incision.The minimally invasive spine surgery (MISS) was introduced in the 1990s and has shown many advantages including less blood loss, less pain, and lower infection incidences.Today MISS is mainly used in the treatment of adolescent idiopathic scoliosis and adult scoliosis. However, due to some inevitable complications, it still can not be routinely applied.This review will briefly summarize the advances in the application of MISS in surgical treatment of adolescent idiopathic scoliosis and adult scoliosis.
