There have been problems in the existing multiple physiological parameter real-time monitoring system, such as insufficient server capacity for physiological data storage and analysis so that data consistency can not be guaranteed, poor performance in real-time, and other issues caused by the growing scale of data. We therefore pro posed a new solution which was with multiple physiological parameters and could calculate clustered background data storage and processing based on cloud computing. Through our studies, a batch processing for longitudinal analysis of patients' historical data was introduced. The process included the resource virtualization of IaaS layer for cloud platform, the construction of real-time computing platform of PaaS layer, the reception and analysis of data stream of SaaS layer, and the bottleneck problem of multi-parameter data transmission, etc. The results were to achieve in real-time physiological information transmission, storage and analysis of a large amount of data. The simulation test results showed that the remote multiple physiological parameter monitoring system based on cloud platform had obvious advantages in processing time and load balancing over the traditional server model. This architecture solved the problems including long turnaround time, poor performance of real-time analysis, lack of extensibility and other issues, which exist in the traditional remote medical services. Technical support was provided in order to facilitate a "wearable wireless sensor plus mobile wireless transmission plus cloud computing service" mode moving towards home health monitoring for multiple physiological parameter wireless monitoring.

Objective To explore the clinical application of pereutaneous transluminal angioplasty(PTA) and endovascular bracket to treat lower extremity arteriosclorotic occlusion.Methods The clinical data of 36 patients(41 affected limbs)with lower extremity atherosclerotic occlusion who were treated with PTA and bracket implantation from Jan 2008 to Dee 2008 were summarized.Results The initial successful rate of PTA wag 95.1% (39/41).The clinical symptoms were considerably improved in 37 affected limbs,representing of pain disappearing,skin temperature increasing and the healing of refractory ulcer.The index of ankle to brachial significantly increased from 0.54±0.11 to 0.79±0.15(before v.s.after therapy).However,no improvement was observed in 3 affected limbs,and one affected limb Wag re-operated by the amputation.In the following 3 to 15 months.three superficial femorsI arteries were re-obstructed at the 5th,6th,12th month,respectively.One arteria tibialis pesterior was re-obstructed at the 8th month.The cumulative cure rate was 89.7%(35/39).Conclusions PTA is effective in treating atherosclerotic occlusive diseases.The endovascular bracket can increase the cumulative cure rate.PTA and endovascular bracket are safe and effective in treating lower extremity arteriosclerotie occlusion.

To investigate whether there is mutation in DC-SIGN promoter region in patients with chronic hepatitis B (CHB) and healthy persons previously infected with hepatitis B virus (HBV) and to explore the relationship between the mutation in dendritic cell-specific intercellular adhension molecule-3-grabbing nonintegrin (DC-SIGN) promoter region and HBV.Methods The studied population was composed of two cohorts:47 CHB patients and 20 healthy persons previously infected with HBV.The mutation in DC-SIGN promoter region was detected with PCR,single-stranded conformational polymorphism and heteroduplex analysis,cloning,sequencing and aligning the published DC-SIGN promoter sequence.Results The characteristic mutation within DCSIGN promoter region in HBV infected individuals was observed.In the DC-SIGN promoter region,4 hot spot mutations located in positions - 139,- 142,- 222,and - 336 were observed in the CHB patients,but only 1 spot mutation located in position - 139 was observed in the healthy persons previously infected with HBV.The -336C which was absent in the healthy persons previously infected with HBV was shown in 11 CHB patients (23.40％).The - 139T was far more frequent in the healthy persons previously infected with HBV ( 100％ ) than in the CHB patients (34.04％).Conclusion In the DC-SIGN promoter region,-336C may be a genetic risk factor for developing CHB,but -139T may be associated with protection against HBV.

Objective To observe the time-effect relationship between acupuncture treatment and the absorption of cerebral hematoma and edema in the acute stage of cerebral hemorrhage to determine the optimal time for acupuncture intervention in cerebral hemorrhage.Methods Three hundred patients with cerebral hemorrhage in the acute stage were randomly allocated to treatment groups 1, 2, 3 and 4, and control group, 60 cases each. The control group received symptomatic treatment for regulating blood pressure, reducing intracranial pressure by dehydration, maintaining electrolyte balance, nourishing nerves and preventing and treating complications. The treatment groups were given acupuncture in addition. Treatment group 1 received acupuncture at 24 hrs after the attack; treatment group 2, at 72 hrs; treatment group 3, at one week; treatment group 4, at two weeks. Pre-/post-treatment hematoma size parameter difference value and cerebral peripheral edema grade parameters were observed in every group.Results There were statistically significant pre-/post-treatment differences in hematoma size and cerebral edema grade in every group (P<0.01,P<0.05). There were statistically significant post-treatment differences in hematoma size and cerebral edema grade between every treatment group and the control group (P<0.05). There were statistically significant post-treatment differences in hematoma size and cerebral edema grade between treatment group 1, 2 or 3 and treatment group 4 (P<0.05), between treatment group 1 or 2 and treatment group 3 (P<0.05) and between treatment groups 1 and 2 (P<0.05).Conclusions Acupuncture has a positive therapeutic effect in patients with cerebral hemorrhage in the acute stage. The earlier acupuncture intervention in the acute stage of cerebral hemorrhage, the more remarkable the effect.

This study analyzed the current clinical terminology standardization, systematization research status of traditional Chinese medicine(TCM). The previous version of the TCM clinical term system had some problems including imperfect classification structure, unclear relationship between concepts and so on, which made the TCM clinical terminology system(TCMCTS) difficult to support the clinical practice of TCM. The suggestions for system improvement were using ontology method to build TCMCTS concept model bases on the previous researches and data extracted from TCM clinical electronic medical record, and top-level-ontology accordance with ISO standards. The study also tried to summarize the ‘semantic network between classes’ through semantic relationships.

BACKGROUND:Previous studies have reported that rapamycin can affect the proliferation, migration and adhesion abilities of endothelial progenitor cels, but there is no report on the effect of autophagy, as wel as the interaction between autophagy and apoptosis. OBJECTIVE: To observe the effect of rapamycin activated autophagy activation on the proliferation, apoptosis, and cycle of endothelial progenitor cels. METHODS:Density gradient centrifugation was used to obtain mononuclear cels from bone marrow, and the mononuclear cels were inoculated on human fibronectin-coated culture plate.Then after cultured for 7 days the adherent cels colected were the endothelial progenitor cels. Different concentrations of rapamycin (0.01, 0.1, 1 and 10 μg/L) were added and cultured for 24 hours. Western blot was used to detect the LC3-II protein expression and monitor the induction of autophagy, flow cytometry was used to observe the cel cycle progression and apoptosis changes, and methylthiazolyldiphenyl-tetrazolium bromide colorimetric assay was used to observe the proliferation ability. Meanwhile, the ultrastructural changes were observed under transmission electron microscope. RESULTS AND CONCLUSION:Compared with the control group, there was no significant increasing of LC3-II protein expression of endothelial progenitor cels in 0.01 μg/L rapamycin group, and the LC3-II protein expression was in the high level. The LC3-IIprotein expression in the 1 μg/L and 10 μg/L rapamycin groups was higher than that in the control group, but lower than that in the 0.01 μg/L rapamycin group, which indicated that autophagywas particularly active when the concentration of rapamycin was 0.01 μg/L. The apoptosis of endothelial progenitor cels was increased with the increasing of concentration of rapamycin, and the proliferation rate was decreased with the increasing of concentration of rapamycin. The results indicate that activation of autophagy by bapamycin can promote the cel apoptosis, change the cel cycle significantly, and can inhibit the proliferation of endothelial progenitor cels.

Objective:To investigate the neuroprotective effect and possible mechanism on rats with low dose Lipopoly -saccharide ( LPS) preconditioning after spinal cord injury.Methods:120 female SD rats were randomly divided into the empty virus (EV) group,LPS+empty virus (LPS+EV) group,Nrf2 interference virus (NIV) group,LPS+Nrf2 interference virus (LPS+NIV) group.The model of traumatic spinal cord injury ( TSCI) was established by the modified Allen′s method,motor function of the rat hind limb was assessed by the Basso Beattie and Bresnahan (BBB) score at 1,3,7,14 and 28 d after the operation.The injured spinal cord tissue samples were harvested at each time ,and the pathological changes of rat spinal cord were observed by HE staining ,the Nissl body and neuron survival index were observed by Nissl staining ,the expressions of Nrf2 and GCLC protein level were detected by immunohis-tochemical staining and Western blot.Results:The rat BBB score of LPS+EV group increased significantly than EV group at 7,14,28 d after operation ( P<0.05 ,P<0.01 );The NIV group between LPS+NIV group have no statistical significance at each time.As compared with EV group:the Nrf2 protein of LPS+EV group was expression increased significantly and Nissl staining showed that the neurons survival index was increased at 1,3 and 7 d(P<0.05,P<0.01);The GCLC protein of LPS+EV group was expression increased significantly at 1-14 d( P<0.05 );HE staining showed that the injured spinal cord pathological changes of LPS +EV group was obviously improved.Conclusion:Low dose lipopolysaccharide preconditioning can accelerate the nerve function recovery on rats with traumatic spinal cord injury ,the mechanism may be regulated by activating the Nrf 2 antioxidant stress pathway.

In recent years, the research hot in the field of solid tumor and blood tumor focuses on the myeloid-derived suppressor cells (MDSCs).In tumors, MDSCs not only exert immunosuppression by inhibiting T cell proliferation, destroying the functions of natural killer cells and recruiting regulatory T cells, but also play non-immunosuppression roles in the promotion of angiogenesis and tumor metastasis.All of these hinder the anti-tumor therapy, and particularly affect the curative effect, which are related with a poor clinical prognosis.MDSCs can be used as prognostic markers, which provide new targets for immunotherapy.

Objective To discuss the protective effect of doxofylline on radical surgery for esophageal cancer.Methods Under elective general anesthesia, 60 cases, 35 males and 25 females, aged 45-70 years, BMI 20-30 kg/m2, ASA physical status Ⅰ or Ⅱ, FEV1%>50%, underwent radical surgery for esophageal cancer at middle and distal parts.Random number table was employed to divide these patients into two groups: doxofylline group (group D) and control group (group C) with 30 cases in each.After a routing intravenous induction in the two groups, mechanical ventilation was conducted after bronchial intubation with double channel catheter on the right side.The intravenous injection of doxofylline 4 mg/kg in group D was administrated 30 min after bronchial intubation with double channel catheter.Equal normal saline was instilled to the patients in group C.Blood samples were taken from radial artery to detect the levels of TNF-α, IL-6, IL-10, MDA and SOD at four time points: 10 min (T0) before the one-lung ventilation, 60 min after OLV (T1), after two-lung ventilation (T2) and the end of the operation (T3).Meanwhile, the blood and breath at these time points were tested.The occurrence of OLV, blood loss volumes, fluid input quantities, urine volumes, postoperative hyoxemia and pulmonary inflammation were observed.Results Compared with T0, the activity of SOD in serum and PaO2 in the two groups at T1-T3 decreased (P＜0.05).The concentrations of TNF-α, IL-6, IL-10 and MDA increased significantly (P＜0.05).Compared with group C, the activity of SOD activities and PaO2 in group D at T1-T3 increased while concentrations of TNF-α, IL-6, IL-10 and MDA decreased significantly (P＜0.05).The occurrence rates of postoperative hyoxemia and pulmonary inflammation in group D were obviously lower than those in group C (P＜0.05).Conclusion Doxofylline can suppress patients' inflammatory response and oxidative stress response after OLV and reduce the incidence rates of postoperative hyoxemia and pulmonary inflammation as well as alleviate lung injury triggered by radical surgery for esophageal cancer.
