This study proposed to use Term Frequency - Inverse Document Frequency (TF-IDF) relative entropy as knowledge representation method between symptoms and syndrome. TF-IDF was originated from text mining. It was an important method in the automatic text categorization. TF-IDF also represented the automatic categorization idea in traditional Chinese medicine (TCM) syndrome. It was based on the fact that the higher frequency of one symptom in specific syndrome, the stronger ability to distinguish this syndrome (TF); and the more wide range of one symptom in all syndrome, and the lower ability to distinguish a syndrome (IDF). It was verified with specific examples.

Phytoene synthase is a rate-limiting enzyme in the pathway of carotenoid biosynthesis.To aim at establishing a transformation of Ginseng callus cells, elevating the nutritive value through encouraging the composition of corresponding carotenoid,taking Ginseng callus cells as acceptor,psy gene were transformed into cells via Agrobacterium-mediated. The factors affecting genetict ransformation were also investigated seperately from concentrations of A.tumefaciens, age of Ginseng callus cells, infection time and co-culture time. PCR,PCR-Southern and RT-PCR analysis from the transferred gene plants proved that psy gene has been transferred into Ginseng callus cells and can be expressed. The content of ?-carotene was increased by an average of 26 times.A base of improving and raising the contents of carotenoid in the Ginseng callus cell was established.

Objective To further investigate the association among clinical pathology,complement activation and renal secretory IgA (SIgA) deposition in patients with IgA nephropathy (IgAN).Methods The activation of serum complements were detected by immunoturbidimetry and ELISA.Renal deposition of SIgA and activation of complements were detected by immunofluorescence.Then the association among clinical pathology,complement activation and renal SIgA deposition were analyzed in IgAN patients.Results In all 201 patients with IgAN,59 patients had SIgA deposition with higher incidences of mucosal infection history and hematuria (P ＜ 0.05),lower levels of serum cystatin C,β2 microglobulin and lower tubulointerstitial lesion grades and T-grade in the Oxford classification (P ＜ 0.05),when compared with patients without SIgA deposition.Both alternative and mannose binding lectin (MBL) pathways were activated in patients with or without SIgA deposition.Patients with MBL pathway activation had lower estimate glomerular filtration rate (P ＜ 0.01),higher serum creatinine,higher proportion of glomerulosclerosis and S-grade in the Oxford classification,more severe tubulointerstitial lesion (P ＜ 0.05).Conclusions Compared with patients without SIgA deposition,patients with SIgA deposition have a stronger link to mucosal immune.The deposition of SIgA is associated with different clinical and pathological manifestations;however,the complement activation is similar in both groups of patients.Patients with MBL pathway activation show more severe kidney injury.

BACKGROUND:Epidural scar after laminectomy is one important reason for the secondary spinal stenosis, and local application ofSanqi sodium hyaluronate gel can prevent epidural scar adhesion after laminectomy. OBJECTIVE: To study the effects ofSanqisodium hyaluronate gel on α-smooth muscle actin expression in the process of rabbit's epidural scar formation. METHODS: In this study, there were ninety-six rabbits which were randomized into four groups and given 0.5 mL normal saline, 0.5 mLSanqi concentrated solution, 0.5 mL sodium hyaluronate and 0.5 mLSanqisodium hyaluronate gel around the dura. At 1, 2, 4, 8 weeks after treatment, immunohistochemistry staining was employed for analysis of α-smooth muscle actin expression. RESULTS AND CONCLUSION:At the end of weeks 1 and 2, the expression of α-smooth muscle actin antibody in the normal saline group was significantly higher than that in the other three groups (P < 0.01 orP < 0.05), but there were no significant differences among the Sanqi, sodium hyaluronate andSanqisodium hyaluronate gel groups (P> 0.05). At weeks 4 and 8, the expression of α-smooth muscle actin antibody in theSanqi sodium hyaluronate gel group was significantly lower than that in the other three groups (P < 0.01 orP < 0.05), and there was no significant difference among the latter three groups (P > 0.05). These findings suggest thatSanqi sodium hyaluronate gel can inhibit the expression of α-smooth muscle actin, and thus ease scar contracture.

By using a micro-sensor through an endoscope,the esophageal variceal pressure in 94 patients with cirrhosis was measured.The results of the measurement were as follow:in 5 cases with Ⅱ-degree,it was 2.68?0.18 kPa,varices in 26 cases with Ⅲ-degree,it was 2.90?0.23 kPa,while in 63 cases of Ⅳ-degree varices,it was 3.51?0.33 kPa.The results suggested that there was a significant correlation between the pressure of esophageal varices with the degree of varices (r=0.313,P=0.01).The method seemed to be a valuable non-invading technic for evaluating the degree of varices.

The connotations of "du-fu" and "Sanli" in "Sanli acupoint for du-fu diseases" are discussed in this paper, which can provide theoretical foundation for the clinical application of "Sanli acupoint for du-fu diseases". Based on ancient literature combined with related theories in the Huangdi Neijing (Yellow Emperor's Canon of Internal Classic), a deep discussion is performed through the relationship between Zusanli (ST 36) and stomach, indication and mechanism of Zusanli (ST 36) on du-fu diseases and comparison between Zusanli (ST 36) and Shousanli (LI 10). It is believed that "du" should be pronounced as "dŭ", meaning stomach, and it indicates that Zusanli (ST 36) is closely related to stomach and spleen when it is used for du-fu diseases; "fu" means abdomen area, including liver-gallbladder, spleen, stomach-intestine, kidney, uterus, triple energizer; "sanli' means exclusively the acupoint of Zusanli (ST 36).

ObjectiveTo investigate the treatment effects of comprehensive nursing intervention on patients with chronic obstructive pulmonary disease(COPD) treated by non-invasive mechanical ventilation with BiPAP mode.Methods96 patients with diagnosed COPD and using non-invasive mechanical ven- tilation with BiPAP mode were randomly divided into the control group(46 cases) which was treated with routine measures and the comprehensive nursing intervention group (50 cases) which adopted comprehen- sive nursing intervention according to experimental design. The frightening degree, incidence rate of com- plications and clinical treatment effect by ventilator were compared between the two groups.ResultsPa- tients compliance with treatment and clinical treatment effect by ventilator in the comprehensive nursing in- tervention group was better than that of the control group. The frightening degree and incidence rate ofcomplications were lower than those of the control group (P < 0.01 ).ConclusionsComprehensive nurs-ing intervention with non-invasive mechanical ventilation with BiPAP mode can improve the treatmentcompliance of COPD patients,reduce complications followed by non-invasive mechanical ventilation andreach the prospective treatment effect.
