PURPOSE: This study is aimed at obtaining the information on the physical fitness level of female flight attendants at a local airline. METHODS: The subjects are 2,409 female flight attendants who have had medical examination and physical fitness tests at an airline medical center from January 2 to December 30, 2008. The independent variables include socio-demographic & behavioral characteristics, and medical examination results, whereas the dependent variable is their physical strength score representing their fitness level. RESULTS: Factors that affect the fitness strength score are age, flight hours per year, and fasting blood sugar level. It is found that physical fitness level is higher when the subjects are over 35, on board for over 850 hours per year and their fasting blood sugar level is over 100 mg/dL. CONCLUSION: It is concluded that for the improvement of flight attendants' health, more exercise to develop cardio-respiratory endurance and muscular strength is needed, and further study needs to be done to develop fitness enhancement programs considering flight attendants' job characteristics, working years, and flight hours per year, and programs for those returning to their workplace after a long-term leave, and new employees.

Objective To investigate the effect of brain-derived neurotrophic factor (BDNF) gene modified neural stem cells (NSCs)transplantation on cerebral ischemic injury in rats.Methods NSCs from newborn rat hippocampus were isolated,cultured in a medium containing fibroblast factor (FGF) in vitro. Their proliferation and differentiation were detected by immunohistochemistry.Virus vectors pLXSN-BDNF were built and BDNF were transfected into NSCs.Biological activity were detected to obtained engineering stem cells of BDNF protein with secretary activity.Middle cerebral artery occlusion (MCAO) models were made and transplanted with NSCs-BDNF by stereotaxic technique.The effect of transplantation on MCAO models was evaluated histologically and behaviorally.Results Statistical analysis showed that the behavioral performance of the animals improved after transplantation (Longa mark being 1.343?0.293 four weeks after stem cell transplantation).The number of hippocampal dentate gyrus neurons increased to 87.5%?6.6% , four weeks after stem cell transplantation on Nissle stained hippocampal sections,which was significantly different from that of controls.Positively BrdU stained neural stem cells revealed by immunohistochemistry in the cultured cells and in the transplanted brain sections,indicated that the engineering cells transplanted had survived in the host brain and began to proliferate.Conclusion Transplantation of BDNF genetically modified NSCs can effectively promote the recovery from cerebral ischemic injury.

This paper described the results of the optimal method for preparation and extraction of lectin from Phaeoporus obliquus(Pers ex Fr).(J.Schroet).We determined the optimal buffer solution using the ag-glutination test with 2% hare blood cells.The optimal extraction process included the following parameters that were conformed by optimization analysis: material-water ratio,extraction time,concentration of sodium chloride and the pH value.The results are that the agglutination indexes of POL using TBS and PBS extrac-tion buffer were 64 and 16,respectively.The optimal extraction process is that,the material-water ratio was 1:50,the extraction time was 20 h,while the concentration of sodium chloride was 0 mol/L and pH was 8.0.The agglutinability of POL was 256 examined by this method.The optimized extraction process is stable and practicable,which may supply some basis for the application of the lectin from Phaeoporus obliquus in immunoregulation.

Valproic acid is a commonly prescribed medication approved for epilepsy, migraine and bipolar disorder. The common adverse effects associated with valproic acid include nausea, vomiting, tremor and weight gain. Less common but more serious adverse effects can occur. These include irreversible hepatotoxicity and pancreatitis. We report one case of pancreatitis, an uncommon disorder in children, in an 11-year-old boy treated with valproic acid for simple partial seizure.

Objective To analyze the surgical procedure and effect of living-related small bowel transplantation(LR-SBTx) on intestinal function failure caused by short bowel syndrome.Methods A boy, 15 years of age with short gut syndrome, who had only 8 cm of residual small intestine, associated with serious malnutrition and poor D-xylase absorption test (0.226/5h). The donor was the boy's mother. They had a match of 4 loci in HLA. In the first stage of the surgical procedure, 120 cm of ileum from the patient′s mother was transplanted into the recipient. Both ends of the transplanted intestine were exteriorized as stomas on the patient′s abdominal wall. The second stage of reconstruction of the intestine was carried out 6 months after his first operation. The residual small bowel of the recipient was transected, and both of its ends were respectively anastomosed end-to-side to the proximal and distal segments of the graft. The stomas of the graft were left in place. Results The donor and recipient operation went on smoothly. Acute rejection and infection of CMV developed postoperatively and were cured after treatment. The patient was followed-up for 8 months, the graft function recovered gradually postoperatively with increase of body weight. He can ingest a semifluid diet and take care of himself independently. Conclusions LR-SBTx is an effective way to treat short bowel syndrome. The reconstruction of the intestine in two stages for LR-SBTx decreased the risk of complications. Rejection and infection are important risk factors of LR-SBTx.

Objective: To observe the efficacy of electroacupuncture (EA) plus Yi Jin Jing (Sinew-transforming Qigong Exercises) for knee osteoarthritis (KOA). Methods: A total of 60 patients with KOA were divided into an observation group and a control group according to the random number table method, with 30 cases in each group. Patients in the observation group received the treatment of EA plus Yi Jin Jing (Sinew-transforming Qigong Exercises), while patients in the control group only received EA treatment. Both groups were treated for 5 weeks. The changes of Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and visual analog scale (VAS) scores in the two groups were observed after treatment. Results: After treatment, the total effective rate in the observation group (92.3％) was significantly higher than that in the control group (70.0％), (P<0.05); the WOMAC and VAS scores in both groups were significantly lower than those before treatment, showing statistical significance (all P<0.01); there were significant differences in the post-treatment changes in the WOMAC and VAS scores between the two groups (P<0.05, P<0.01). Conclusion: EA plus Yi Jin Jing (Sinew-transforming Qigong Exercises) is clinically effective for KOA. This combined treatment can alleviate clinical symptoms.

BACKGROUNDThe risk of clinical deterioration still exists in the acute phase despite the fact that patients with minor stroke may display less severe symptoms. The impact of this clinical deterioration on long-term outcomes is unknown. We characterized the clinical features of neurological deterioration (ND) in the acute phase of minor ischemic stroke (MIS) and investigated its impact on mid- and long-term outcomes.

METHODSThis was a multi-centered, prospective clinical study involving patients with MIS (the National Institutes of Health Stroke Scale, NIHSS ≤3) recruited from the China National Stroke Registry. Patients were included who had been hospitalized within 24 hours of stroke onset. Baseline characteristics, complication rates during hospitalization, etiology of stroke, as well as 3-, 6-, and 12-month post-stroke outcomes were compared between patients with and without ND during the acute phase.

RESULTSA number of 368 (15.2%) out of 2424 patients included in the study exhibited ND in the acute phase. Compared to patients without ND, patients with ND had longer hospital stay, increased rate of baseline diabetes, and multiple complications. Multivariate Logistic regression indicated that ND in acute phase was an independent factor predictive of increased dependence (adjusted odds ratio = 5.20, 95% CI, 3.51-7.70, P < 0.001) at 12-month post-stroke.

CONCLUSIONSThe risk of ND in the acute phase is high in patients with MIS. ND in the acute phase is an independent predictor for poor outcomes at 12 months post-stroke onset.

OBJECTIVETo present data from a baseline investigation on stroke-related cohort population in rural area of Shanghai.

METHODSA cross-sectional study was carried out in a cluster sampling population aged 40 years and over. General information and data on common risk factors in the population were gathered and cerebral vascular hemodynamic indexes were checked. Hemodynamic score was estimated according to single indexes by unified methods. 5335 persons who had met the inclusion criteria were enlisted in the study. Exposure level of risk factors, prevalence of stroke, and hemodynamic indexes were analyzed and distributional characteristics were described.

RESULTSExposure rate of hypertension, heart disease, diabetes, family history of hypertension, overweight or obesity in males were 31.74%, 6.09%, 1.16%, 3.22%, 17.64%, 29.68% and were 32.76%, 9.22%, 1.55%, 3.84%, 19.22%, 29.44% in female respectively. Standard prevalence of stroke was 1167.3/100000, which in male was significantly higher than that in female (P < 0.05). The change of cerebral vascular hemodynamic indexes was significantly associated with age. Hemodynamic score in 21.3% of the subjects was below 75 points.

CONCLUSIONSAmong population of 40 years old and over in rural areas, hypertension was the principal risk factor regarding the rate of stroke. Prevalence of stroke in males was significantly higher than that in females. Abnormal rate of hemodynamic score was about 20% in this population.

OBJECTIVETo probe into the relationship between hypertension and hemodynamic score of cerebral vascular accumulative function by though studying the history of hypertension and level of blood pressure.

METHODSThe database of blood pressure and cerebral vascular hemodynamic indexes (CVHI) were from baseline data and measurement in a cohort. 18,512 participants who met the included criteria were enlisted in the study. The function scores were estimated using uniform methods according to CVHI. Participants were grouped by age, years of having hypertension and level of blood pressure. Differences of the function score between different groups were compared.

RESULTSThe function score in hypertension group was significantly lower than that of normal tension group, which decreased by 13.3 points. Within 5 years of hypertension history, the function score decreased as course of hypertension prolonged. The same trend was found between the score and level of both systolic and diastolic blood pressure. When systolic blood pressure elevated to 140 mmHg or diastolic blood pressure elevated to 95 mmHg, the function score was below 75 points.

CONCLUSIONThere were significant relationship between decrease of the function scores and medical history, course of hypertension as well as level of blood pressure.
