By studying the relationship between fingertip temperature changes and arterial function during vascular reactivity test, we established a new non-invasive method for detecting vascular function, in order to provide an assistance for early diagnosis and prevention of cardiovascular diseases. We customized three modules respectively for blood occlusion, measurement of finger temperature and blood oxygen acquisition, and then we established the hardware of data acquisition system. And the software was programmed with Labview. Healthy subjects [group A, n=24, (44.6±9.0) years] and subjects with cardiovascular diseases [group B, n=33, (57.2±9.9) years)] were chosen for the study. Subject's finger temperature, blood oxygen and occlusion pressure of block side during and after unilateral arm brachial artery occlusion were recorded, as well as some other regular physiological indexes. By time-domain analysis, we extracted 12 parameters from fingertip temperature signal, including the initial temperature (Ti), temperature rebound (TR), the time of the temperature recovering to initial status (RIt) and other parameters from the finger temperature signal. We in the experiment also measured other regular physiological body mass index (BMI), systolic blood pressure (SBP), diastiolic blood pressure (DBP) and so on. Results showed that 8 parameters difference between the two group of data were significant. based on the statistical results. A discriminant function of vascular function status was established afterwards. We found in the study that the changes of finger temperature during unilateral arms brachial artery occlusion and open were closely related to vascular function. We hope that the method presented in this article could lay a foundation of early detection of vascular function.

Early detection of vascular function plays an important role in the prevention and treatment of cardiovascular diseases (CVDs). This paper reports the main studies of the effectiveness of fingertip temperature curve in digital thermal monitoring (DTM) for predicting CVDs, as well as the relationship between parameters from DTM and pulse wave velocity (PWV) detection. A total of 112 subjects [age (42.18±12.28) years, 50% male, 37 with known CVDs] underwent DTM and PWV detection. Results showed that most of parameters related to CVDs were from the declining stage of the digital thermal signal. Binary Logistic regression models were built, and the best one was chosen by ten-fold validation to predict CVDs. Consistency was great between the detection result of PWV and that of the Logistic model of DTM parameters. Parameters from DTM also contained information for early detecting of vascular stiffness. This study indicates that the fingertip temperature curve in DTM has a potential application for predication of CVDs, and it would be used to access vascular function in the initial stage of CVDs.
ObjectiveTo investigate the clinical effects of early enteral nutrition in severe thoracic trauma patients requiring mechanical ventilation. MethodsWe randomly allocated 60 patients with thoracic trauma requiring mechanical ventilation into two groups by drawing lots including an early enteral nutrition (EEN) group and a parenteral nutrition (PN) group in our hospital between January 2013 and September 2014 year. There were 30 patients in each group. We compared the recovery results of the patients between the two groups. ResultsAfter the treatment of 7 and 14 days, indicators in the EEN group were better than before significantly and better than those in the PN group; diarrhea rate average days of ICU and the average days of hospital decreased significantly with statistical differences (P<0.05). There was no statistical difference in ventilator-associated pneumonia or the incidence of stress ulcer between the two groups (P>0.05). ConclusionEarly enteral nutrition in severe chest trauma patients requiring mechanical ventilation may promote protein synthesis, improve the nutritional status of patients, correct negative nitrogen balance, reduce inflammation response, reduce the complications.
Objective To evaluate the feasibility of the clinical pathway based on the medical data information integration system to guide the treatment of palmar hyperhidrosis (PHH). Methods We retrospectively analyzed the clinical data of 106 PHH patients in the Fourth Affiliated Hospital of Harbin Medical University from March 2012 through June 2015. The patients were divided into two groups including a day surgery group (52 patients) and a traditional group (54 patients). The patients in the day surgery group underwent day surgery guided by clinical pathway of PHH based on medical data information integration system. The patients in the traditional group stayed in hospital for 2-3 days. The pre-surgical situation, post-surgical effect of patients and cost of hospitalization were compared between the two groups. Results Only one patient of PPH suffered from insufficient relief of symptoms. The other patients’ symptom of PPH disappeared. No serious complication occurred. The postoperative visual analogue scale (VAS) pain score of patients was lower than 2 points. The hospitalization expense of the day surgery group was significantly lower than that of the traditional operation group. The average follow-up time was 2.5 months (0.5 to 4 months). The symptoms of the whole group had no recurrence. All of the patients were not found with compensatory hyperhidrosis. Conclusion Day-surgery clinical pathway of PHH based on medical data information integration system is safe and feasible. Day-surgery clinical pathway of PPH can accelerate the recovery of patients and save the cost of hospitalization.
