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 explore possible mechanisms of the cross-over observed in stroke patients comple-ting a line bisection test. Methods Twenty-five stroke patients with left neglect and twenty normal subjects were studied.In the ordinary line bisection test,there are two papers presenting 20 mm and 100 mm lines respectively.On each paper,three lines with the same length are presented at the left,middle and right of the paper.In the line im-age test,the two papers are the same as in line bisection test,but here subjects are asked to set endpoints of each re-al line. Results Replicating earlier findings,length cross-over was observed in the patients with neglect.In the hline image test,those patients neglected lines on both sides but with a much larger proportion on the left.The patientsunderestimated long lines as in previous studies,but they also underestimated very short lines in contrast to earlier findings. Conclusion Foveal neglect sparing may explain these observations.For very short lines,the left end of the line falls into foveal vision and the left part of the line was not neglected.As a result,the crossover effect of line length occurs.

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 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.
