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.

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.

Objective To review the clinical characteristics of left ventricular pseudo-aneurysm (LVPA) in China mainland.Methods The China National Knowledge Infrastructure (CNKI),Wanfang Data,VIP information and PubMed database were searched to extract information on clinical profile,diagnostic imaging,treatment and outcome of patients with LVPA from January 1986 to April 2012.Results Clinical data of 77 patients with LVPAs (including 5 coexistent with true aneurysm) were extracted from 65 articles.There were 56 males (72.7％) and 11 females (27.3％) with a median age of 48 years old(range 5 to 82).The most common etiology was myocardial infarction (40,51.9％).Breathlessness/dyspnea (44.6％),chest discomfort (41.9％) and chest pain (41.9％) were the most frequently reported symptoms,but asymptomatic patients accounted for 10.8％ of all.86.4％ of the patients had electrocardiographic abnormalities,most of which were nonspecific ST segment changes.No event of thromboembolism was reported.Transthoracic echocardiography was the most commonly used diagnostic imaging test,followed by angiography with which no complication was reported.19 cases of pseudo-aneurysms(24.7％)were reported to rupture and 15 patients(19.5％) died,mostly of cardiac tamponade and sudden death.Conclusions LVPA is a rare and life-threatening disorder.It lacks of specific clinical manifestations distinguishable from coronary disease or heart failure.Emergency surgery is warranted once it is identified.
