Objective To explore a kind of biomedical signal pattern (BSP) with a new method called as state representation methodology (SRM ) .Methods Based on the heart sound signals ,ECG signals ,breathing ,as the important research problem for BSP description ,with some comparisons on several traditional methods ,in which support vector machines (SVM ) and response sur-face methodology (RSM ) etc .,using frequency slice wavelet transform (FSWT ) method to extract the BSP signal dynamic damping characteristics ,thus ,this paper proposes a new idea of SRM analysis .In the case of heart sound signal analysis ,the general steps of SRM evaluation method is given .Results In 40 cases of normal heart sounds SRM model is set up ,with 80 cases of abnormal heart sounds are compared ,the obvious differences of the SRM state distributions of the two groups are found .Conclusion The combi-nation of SRM with FSWT can provide a novel approach for BSP analysis ,and provide powerful development tool for the analysis of BSP .

Objective The current study was to investigate the clinical and pathological features of macroscopic hematuria associated acute kideny injury (MH-AKI) in patients with IgA nephropathy (IgAN) and its associated prognostic factors.Methods We performed an analysis on the clinical and pathological features of biopsy-proven IgAN patients diagnosed during 2004 to August of 2007,who had experienced MH associated AKI.The patients enrolled in the study were followed up.The renal lesions were evaluated with Katafuchi pathological scores of IgAN.Results 5 patients with IgAN had experienced at least one episode of MH-AKI,accounting for 1.3% of IgAN diagnosed during the same period and 13.5% of IgAN patients with macroscopic hematuria.High proportion of tubules filled with red blood cell casts and tubular injury were demonstrated in all biopsy specimens.Renal function of 3 patients completely recovered within 14 days.One patient (patient 4) got quick recovery in the first month of the disease but completely recovered 418 days later.The other patients only had an incomplete recovery during the 20-month follow-up.The incompletely recovered one had relatively an older age,longer persistence of MH,more sclerotic glomeruli and a more severe tubule-interstitial damage.Conclusion AKI is commonly seen during episodes of MH in patients with IgAN.Not all patients with MH-AKI showed a complete recovery.Age,duration of MH,proportion of glomerular sclerosis and the severity of tubular necrosis might be the risk factors of an incomplete recovery of renal function.

Objective To compare the effect of target-controlled infusion (TCI) and manual controlled infusion (MCI) of propofol in out-patients undergoing gastroscopy with the sedative depth monitoring by bispectral index (BIS).Methods Forty-eight patients with physical status Ⅰ-Ⅱ scheduled for an elective gastroscopy under general anesthesia were enrolled in this study. All patients were randomly divided into two groups, group T (n=24) and group M (n=24). Before induction, all patients were received a single dose of fentanyl (1 ?g/kg) intravenously. With the monitoring of BIS, the gastroscope was inserted in by the time of BIS value less than 60. Patients in group T received a propofol infusion with the initial plasma concentration of 1 ?g/ml and then the dose was titrated upward by 0.5 ?g/ml each time till the BIS values was less than 60 and then propofol was maintained at a concentration of 2-3 ?g/ml. In the group M, propofol was infused at a rate of 4 g/h until the BIS was less than 60 and then propofol was administrated at a rate of 4-6 mg?h -1?kg -1. During the period of gastroscopy, the sedation depth was maintained by BIS value of 40 to 60. The infusion was stopped by the end of biopsy in both groups. The time from induction to put in the endoscopy, the examination maintenance and the duration of anesthesia, the induction and total amounts of propofol infused were recorded and the average infusion rate was calculated. Results The induction time was significantly shorter in group T than in group M. The duration of examination, time from the induction to opening the eyes and time from induction to the orientation were not significantly different between two groups. Propofol consumption for induction and maintenance was much higher in group M than in group T. The average infusion rate was not significantly different in both groups. The BIS values were almost same at the beginning of gastroscopy and at opening the eyes. The plasma concentration and effect-site concentration were (4.25 ?0.94) ?g/ml and (1.78?0.66)?g/ml at the time of beginning of gastroscopy; while being (1.34?0.39) ?g/ml, ( 1.77?0.40) ?g/ml at the time of opening the eyes. There were 3 cases in group T and 7 cases in group M had sidereactions during the gastroscopy, respectively, but all were mild. Conclusions BIS could be a good sedative depth monitor in total intravenous anesthesia in out-patients gastroscopy. Target-controlled infusion system can help us to get accurate depth of anesthesia quickly and stably, and decrease the consumption of propofol and side effects as well.

Objective To study the effect of lincomycin hydrochloride on the intestinal mucosal barrier of mice. Methods A total of 24 mice were equally and randomly divided into normal control group and model group. Mice in the model group were administered with 8 mg · kg-1 · d-1 of lincomycin hydrochloride through gastric lavage for 3 days to establish the model of intestinal mucosa injury and alteration of intestinal flora in mice. The intestinal flora was tested,bacterial translocation was analyzed,and mucosa permeability was determined by measuring diamine oxidase( DAO)in plasma. Results Lincomycin hydrochloride led to alteration of intestinal flora in mice after oral administration for three days in mice. The aerobes translocation rate was 16. 7% and 52. 3% in the normal and model groups,respectively(P〈0. 01). The anaerobes translocation rate was 8. 3% and 68. 2% in the normal and model groups,respectively(P〈0. 01). The plasma concentration of diamine oxidase was increased from(2. 08±0. 05)mg·mL-1 in the normal group to(7. 18±0. 10)mg·mL-1 in the model group(P〈0. 01). Conclusion Lincomycin hydrochloride damages intestinal mucosal barrier in mice.

Standards of TCM information plays a fundamental and critical role in TCM informatization. In recent years, the standardization of TCM information has made a series of tremendous progress. This article introduced the major work progress of TCM terminological standardization and TCM data standardization in China, and status of TCM information standardization in International Organization for Standardization and World Health Organization. The existing problems in the construction of standardization of TCM information were discussed and suggestions were proposed to solve problems: to build the basic framework of standard system of TCM information; to cultivate professionals for the researches on the international standards of TCM information; to further explore the theories and methods about standardization of TCM information.

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.

Objective To study the effect of Chinese medicine combined with large dose interferon in the postoperative adjuvant therapy of malignant melanoma of the skin.Methods A high dose of interferon alpha-2b (GanLeneng) (1200 IU/per day) was used in 20 cases of malignant melanoma of skin for 7 days.One course of treatment was 3 months,8 consecutive courses of treatment and traditional Chinese medicine (0.25 g) were administered 1 hour before meals,2 times a day,taking three weeks per month.Results One patient in 20 cases of patients did not receive timely treatment and resulted in death.The remaining patients were were still live from 2012 to the present.Local and distant metastasis lesions disappeared during the course of treatment.Conclusions Traditional Chinese medicine combined with high-dose interferon in cutaneous malignant melanoma as adjuvant treatment plays an important role.
