Objective To explore whether health examination save medical insurance fund or not. Methods To observe the sparing medical cost which 371 health examination people avoid repeated checking and shorten the length of stay during hospitalization from March 2006 to March 2007. To observe the effect of sparing medical cost because of regular health examination, early discovery diseases, pretreatment promptly and avoidance transforming to advanced diseases. Results Because of avoiding repeated checking and shortening the length of stay,everybody save the medical cost about 570 yuan,371 people can save about 21 ten thousands yuan. To statistics the average hospital cost of different courses of eight common diseases and malignant tumors from January to November at 2007, we discovered that the medical cost is large distinction between the earlier period and advanced stage of disease. For example: the medical cost of one stage of hypertension is 6608 yuan ,the two stage is 8838 yuan ,the three stage is 13 869 yuan, and the stage of hypertensive heart disease is 13 033 yuan. Parts of health examination crowd who stay at my hospital from 1996 were visited for five years ,we conformed many chronic diseases by prompt intervention can relieve and even reverse, avoiding the transformation to incurable disease which will consume a large number of strength and money. Conclusion Health examination resource is a medical treatment resource which isn't restricted by social security fund, the utilization can not only save medical cost but also discover and treat diseases earlier, thus we can save the strength and money before the advanced diseases.

Objective To explore the alteration in ethology and change of muscle fibers of gastronomies of rats following spinal cord injury(SCI). Methods 108 Wistar rats were divided into sham operation group (n=38) and SCI group (n=38) and rehabilitation group (n=32).The ethology was evaluated by Basso, Beattie, and Bresnahan Locomotor Rating Scale (BBB Scale), and the alteration of muscle tissue's reactivitywas observed by immunohistochemistry staining. Results The BBB scores of rehabilitation group were higher than SCI group 3weeks after injury, but all was lower than 10. The cross section areas of gastrocnemius in both groups were getting smaller, but the rehabilitationgroup was slighter. Conclusion Spontaneous recovery occurred in some degree for rats' hind limb after spinal cord injury. Rehabilitationtraining is beneficial for the recovery of rats' motor function, and alleviates the atrophy of hind limb after spinal cord injury.

Inhibitor of DNA binding 1 (ID1) has an aberrantly high expression in multiple cancer tissues, including colon cancer, lung cancer, breast cancer, and so on, which is closely related to cancer aggressiveness and poor clinical outcomes in cancer patients. It has been reported that ID1 maintains colorectal cancer cells (CRCs) stemness traits and contributes to the CRC drug resistance. While, the biological molecular mechanisms have not been fully elucidated. In this research, we found that ID1 upregulates octamer binding transcription factor (OCT4) protein level as well as OCT4 signaling pathway via Western blot, gene set enrichment analysis (GSEA), dual-luciferase reporter assay, and real-time PCR. Through the in vitro sphere formation assay, we found that overexpression of OCT4 reverses the inhibitory effect of knocking down ID1 on CRC sphere formation ability. With the help of JASPAR and GEPIA database, we predicted a novel transcriptional repressor—forkhead box D3 (FOXD3) of OCT4. Finally, by using co-immunoprecipitation (Co-IP), confocal and real-time PCR, we demonstrated that ID1 interacts with FOXD3 to inhibit its transcriptional repression activity and therefore to upregulate OCT4 transcription and OCT4 signaling pathway. In conclusion, this study provides a new theoretical basis for the regulation mechanism of colon cancer stem cells, and the newly found protein-protein interaction of ID1-FOXD3 provides a potential drug target for the therapy of CRC.

Objective To evaluate the effect of off-pump coronary endarterectomy (CE) plus off-pump coronary artery bypass grafting (off-pump CABG) on patients with chronic total occlusion (CTO) combined with diffuse distal atherosclerosis. Methods From October 2006 to August 2009,65 CTO patients with 176 angiographically confirmed vascular stenosis or occlusive lesions, 70 of which were complete occlusion, underwent off-pump CABG. During the operation, diffuse intimal thickening distal to occlusive lesion was found, and blood flow of the bridges was unfavorable.Results Therefore endarterectomy was performed, followed by CABG. The blood flow in the bridges were 2-10 ml/min versus 14-37 ml/min before versus after endarterectomy. Pulsatility index (PI) was 5.1-15.6 versus less than 5 before versus after endarterectomy. Left ventricular ejection fraction was also improved significantly [before operation: (0.47±0.12)%, after operation: (0. 52±0.15)%, t=2.17, P＜0.05]. Peri-operative myocardial infarction occurred in 2 cases, but without significant cardiac homodynamic changes. And 23 patients underwent coronary angiography to evaluate graft patency 3-18 months after operation, all of them had favorable blood flow. Conclusions It is feasible to perform off-pump CABG plus coronary endarterectomy for patients of chronic coronary total occlusion combined with diffuse distal atherosclerosis. This treatment is safe and effective.

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.

Objective To study the treatment effect by addition of granulocyte-colony-stimulating factor (G-CSF) that could reduce the level of residual disease in patients with Ph-positive chronic myeloid leukemia (CML) who appeared to have achieved a suboptimal response to imatinib (IM) alone. Methods Eleven patients with CML who had achieved≥ 35 % Ph-negativity on treatment of IM were enrolled. The initial dose of imatinib was 400 mg or 600 mg orally daily, and G-CSF, 5 μg/kg subcutaneously daily. The administration of G-CSF was postponed or interrupted in the event of leukocytosis (leukocytes ≥ 30 ×109/L) until the whitecell count fell ＜20 × 109/L. Efficacy was assessed by serial monitoring of blood levels of bcr-abl transcripts.Treatment with G-CSF was discontinued if the patient did not achieve a reduction in the transcript level of at least 0.5 log after 6 months. For patients whose bcr-abl transcript levels continued to decline but had not yet reached molecular remission, treatment was designed to continue for 1 to 6 months. Results Of 11 evaluable patients, nine had an appreciable decline in bcr-abl transcript levels(include 7 cases the reduction was greater than 1 log and 2 cases the reduction was greater than 0.5 log), 2 cases the reduction was lower than 0.5 log.In 7 cases the reduction was greater than 1 log, including five patients who did not achieved complete cytogenetic response and two patients achieved complete molecular responses. No bleeding episodes occurred.No patient discontinued therapy because of toxicity and there were no treatment-related deaths. Conclusion The addition of G-CSF should be considered safely and successfully for patients who fail to obtain optimal response to IM alone and this approach deserves further evaluation.

BACKGROUND:Adipose-derived stem cel s are totipotent stem cel s in the adipose tissue, and have the function of self-renewal and multi-directional differentiation. Human adipose-derived stem cel s are ideal seed cel s with stable genetic milieu and few rejections.
OBJECTIVE:To extract human adipose-derived stem cel s from human omental adipose tissue and to identify the cel s by adipogenic and osteogenic induction.
METHODS:Omental adipose tissues were col ected from surgical patients to isolate and culture adipose-derived stem cel s using type I col agenase digestion, filtration and centrifugation. Cel growth was observed and proliferative curve of human adipose-derived stem cel s were drawn by cel counting method to calculate the doubling time at logarithmic growth phase. After adipogenic and osteogenic induction, induced cel s were identified using oil red O and alizarin red staining, respectively.
RESULTS AND CONCLUSION:Human adipose-derived stem cel s were successful y isolated from the omentum tissues of surgical patients. Adherent cel s were fusiform-shaped and like fibroblasts. The growth curve of passage 3 cel s was in S shape, and the doubling time was 45.90 hours. After adipogenic and osteogenic induction for 2 and 3 hours, respectively, oil red O staining showed unequal-sized orange fat droplets, and alizarin red staining showed typical calcified nodules that were in orange. These findings indicate that adipose-derived stem cel s have the adipogenic and osteogenic capacity.

This study was aimed to elucidate the 5-HT3R molecular mechanism of Radix Paeoniae Albaextract (RPAE) as drug intervention in the treatment of premenstrual syndrome (PMS) model rats with liver-qi depression pattern.PMS model rats with liver-qi depression pattern were prepared.And then,the model was treated with RPAE.The protein distribution of 5-HT3AR and 5-HT3BR in the frontal lobe was evaluated by the immune fluorescence technology and western blot.The results showed that there were positive expressions of 5-HT3AR and 5-HT3BR in frontal lobe of rats in each group.Compared with the normal group,the 5-HT3AR and 5-HT3BR protein expression levels of the frontal lobe in the model group increased significantly (P < 0.05).Compared with the model group,the 5-HT3AR protein expression level in the frontal lobe decreased significantly after RPAE treatment (P < 0.05).In conclusion,RPAE regulated the protein expressions of 5-HT3AR and 5-HT3BR in frontal lobe,which may be one of the mechanisms for its treatment of PMS with liver-qi depression pattern.
