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.

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).

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.

Objective To study the changes of Na+K+-ATPase,Ca2+Mg2+-ATPase activities in erythrocyte membrane and blood viscosity in children with essential hypertension.Methods The activities of Na+K+-ATPase,Ca2+Mg2+-ATPase in erythrocyte membrane were determined by a colorimetric method.Blood viscosity was measured and analyzed with the statistic analysis SPSS 12.0 software in 50 children from Nov.2004 to Dec.2004 in the people's hospital of guizhou province and adolescents with essential hypertension.Thirty healthy children were collected as control group.Results The activities of Na+ K+-ATPase[(6.12?1.30)?molpi/(gHb?h)and(4.59?1.40)?molpi/(gHb?h)],Ca2+Mg2+-ATPase[(7.46?1.30)?molpi/(gHb?h)and(5.81?1.20)?molpi/(gHb?h)] were lower significantly in hypertension group than those in control group(Pa

Objective To introduce the preliminary experience of using rigid neuroendoscope in repair of spinal meningocele or myelomeningocele. Methods 3 infantile patients aging between 13 months and 22 months underwent the resection and repair of spinal meningocele or myelomeningocele in May, 2013. The operations were performed under the direct visualization of the rigid neuroendoscope in the aid of the intraoperative electrophysiological monitoring. All the surgical manipulations were accomplished outside the sheath of the endoscope. Results The surgical procedures were smooth. All the patients recovered satisfactorily. There was no postoperative complication. At the one-year follow-up, they were developing normally. Conclusions The rigid neuroendoscope is useful to the resection and repair of spinal meningocele and myelomeningocele. It could simplify the surgical procedures.
