ABSTRACT
Objective To explore the changes of the constituent ratio of hypoglycemic scheme and clinical outcomes of patients with type 2 diabetes mellitus(T2DM)in recent three years in Shihezi. Methods The cluster random sampling methods were used to select 300 patients with T2DM who met the standards in November 2012 from 13 communities in Shihezi. The datasets including general demographic information ,treatment and clinical outcomes were collected by following them up for three years. Results From 2012 to 2015,the proportion of pa-tients with oral drugs decreased from 63.5％ to 51％ while increased from 30.8％ to 41.8％ with insulin treatment. For the patients with insulin treatment ,the rate of patients on single drug therapy declined significantly (χ2 =8.77,P<0.05),while significantly increased on insulin combined with oral drug(χ2=-10.27,P<0.01). The incidence of adverse effects increases from 16.8％ to 24.5％. As compared with 2012,blood sugar levels and con-trol rate had no obvious changes in 2015;namely,according to the standard(1),the control rate of blood glucose in 2015 was 41.2％,decreasing 4.0％as compared with 2012,while according to the standard(2),it increasd by 1.4％ from 2012 to 2015(52.9％). The rate of diabetic complications significantly increased from 2012 to 2015. Conclusions Oral drugs are mainly used in the treatment of T2DM in Shihezi communities,whereas the rate of insulin use elevates. The blood glucose control rate,medication safety,and ability to lower the rate of diabetic com-plications need to be improved in T2DM patients in Shihezi communities.

ABSTRACT
Objective To observe the clinical curative effect of treating reflux esophagitis of spleen qi deficiency syndrome byHezhong-Jianpi decoction.Methods 90 patients in October 2012 to March 2014 in the standard of traditional Chinese medicine hospital of Shanghal were randomly divided into a western medicine group (omeprazole), a Chinese medicine group (Hezhong-Jianpi decoction), and a Chinese and western medicine group (Hezhong-Jianpi decoction + omeprazole), 30 cases in each group. All groups were treated for successive 8 weeks and the changes of the symptoms of integral and esophageal mucosa under gastroscope change situation were observed, and the clinical efficacy was evaluated. Results After the treatment, the esophagus gastroscope integral of the western medicine group, the Chinese medicine group and the Chinese and western medicine group were all significantly improved than those before the treatment group (Z value was respectively -4.351, -4.300, -5.143,P<0.01). Total effective rate was 83.3% (25/30) in the western medicine group, 86.7% (26/30) in the Chinese medicine group, and 90.0% (27/30) in the Chinese and western medicine group, the difference among the three groups was statistically significant (χ2=6.800,P=0.030). The difference of symptoms integral of the western medicine, Chinese medicine, and Chinese and western medicine group was statistically significant (Z values are -5.482, -5.991, -6.120, respectively, P<0.01).Comparison between two groups after treatment showed only Chinese traditional medicine group and the Chinese and western medicine group was statistically significant (Z=-2.113,P=0.040). After the treatment, symptoms as heartburn (Z value -3.390, -3.882, -3.666, respectively), the acid regurgitation (Z value -4.850, -5.004, -5.722, respectively), the food regurgitation (Z value -2.791, -3.422, -2.854, respectively) in the three groups improved significantly than those before the treatment (P<0.01); The retrosternal paln improved significantly in the Chinese and western medicine group after the treatment (Z=-0.873,P=0.380). The pharyngeal foreign body sensation or paln symptoms (Z value were -2.382 and -2.724, respectively), belching symptoms (Z value were -5.074 and -5.061, respectively) in the Chinese traditional medicine group and the Chinese and western medicine group significantly improved after the treatment(P<0.05); The abdominal distension (Z value were 2.772 and -2.032, respectively), the abdominal paln (Z value were 2.26 and 2.02, respectively) in the western medicine group and the Chinese and western medicine group were significantly improved (P<0.05). Conclusion Hezhong-Jianpi decoction can significantly improve the clinical symptoms of reflux esophagitis of spleen qi deficiency, and the curative effect is similar to omeprazole. It has advantage for relieving belch and retrosternal paln. The combined therapy was more effective than eitherHezhong-Jianpi or omeprazole, but no difference was showed in the improvement of esophageal gastroscopy.
ABSTRACT
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 set a quantified diagnostic standard for large intestinal cancer of spleen qi deficiency syndrome. Methods: The spleen qi deficiency syndrome was identified by experts on the basis of clinical epidemiological investigation of 311 patients suffering from large intestinal cancer. Corresponding points were assigned to the correlative factors (traditional Chinese medicine symptoms) on the basis of symptom differences between spleen qi deficiency syndrome and non-spleen-qi-deficiency syndrome. The best threshold was determined by receiver operating characteristic curve (ROC) according to syndrome differentiation from expert team, and the quantified diagnostic standard was established. The syndrome identification from the expert team which was regarded as golden standard was tested retrospectively. Results: All the traditional Chinese medicine symptoms possibly related to spleen qi deficiency syndrome were analyzed based on the opinions of experts, and 28 symptoms were confirmed as candidate correlative factors. The occurrence of 11 symptoms between spleen qi deficiency syndrome and non-spleen-qi-deficiency syndrome showed statistical differences by means of crosstabs analysis (P<0.05). The 11 symptoms were filtered by logistic regression analysis, and tiredness, fatigue, loose stool, and poor appetite were finally determined as the symptoms relative to large intestinal cancer. These four symptoms were analyzed with conditional probability conversion and endowed with 16, 11, 4 and 8 points respectively. The diagnostic standard of spleen qi deficiency syndrome of large intestinal cancer was over 13 points. The sensitivity, specificity and accuracy of retrospective examination were all above 80%, and its positive likelihood ratio was 9.89. Conclusion: The quantified diagnostic standard for spleen qi deficiency syndrome of large intestinal cancer is in accordance with clinical characteristics of large intestine cancer and the characteristics of TCM syndrome diagnosis.

ABSTRACT
Objective To develop a real-time QRS complex detection algorithm of dynamic ECG signals for the GPRS mobile telemonitoring system. Methods Before the first and second derivatives of ambulatory ECG signals were processed by moving average method, the signals sampled from CM5 monitoring lead were filtered with the average of continuous four ECG sample signal points. The R waves could be detected precisely by local minima of second derivatives and Q & S waves were located correctly by cross-zero points of first derivatives of ambulatory ECG signals in a short-time searching windows. The QRS recognition thresholds, which could revise themselves according to the detected values and vary with the analyzing signals, were designed in this paper. Results With a polynomial computation complexity, the novel algorithm insensitive to baseline draft and noise caused by mobile communication filtered power-line interference and most of muscle noise and reduced the search time below 0.02 s during detecting each Q wave, R wave and S wave. For the normal and clinical patients, this algorithm correctly detected up to 99.8% of the QRS complex of ambulatory ECG signals. Conclusion The algorithm can meet the need of real-time QRS complex detection and analysis for the GRRS mobile ECG telemonitoring system.
ABSTRACT
Modern medicine generates a great deal of information stored in the medical database. Extracting useful knowledge and providing scientific decision-making for the diagnosis and treatment of disease from the database increasingly becomes necessary. Data mining in medicine can deal with this problem. It can also improve the management level of hospital information and promote the development of telemedicine and community medicine. Because the medical information is characteristic of redundancy, multi-attribution, incompletion and closely related with time, medical data mining differs from other one. In this paper we have discussed the key techniques of medical data mining involving pretreatment of medical data, fusion of different pattern and resource, fast and robust mining algorithms and reliability of mining results. The methods and applications of medical data mining based on computation intelligence such as artificial neural network, fuzzy system, evolutionary algorithms, rough set, and support vector machine have been introduced. The features and problems in data mining are summarized in the last section.
