RESUMEN
Objective To observe the safety and efficacy of RPH with the simplified. Milligan-Mor- gan(M-M) surgery on mixed hemorrhoids. Methods Totally 1 200 patients with mixed hemorrhoid were assigned to the control group(600 cases) and the treatment group(600 cases) according to randomized, parallel controlled,multi-center trial design. Patients in the control group received PPH with the simplified M-M surgery, and patients in the treatment group received RPH with the simplified M-M surgery. Postop- erative complications, operation time,the postoperative hospitalization days and the efficacy were ob- served. Results Compared with the control group, the numbers of postoperation hemorrhage, postop- erative uroschesis, anal fissure and anorectal stenosis in treatment group were decreased(P <0. 01 , P < 0. 05), operation time and the postoperative hospitalization days were decreased (P <0. 01 , P <0. 05 ), the cure rate for 3 and 12 months after operation were increased (P <0. 01, P <0. 05). Conclusions RPH with the simplified M-M surgery could reduce the incidence of postoperative complications,improve the clinical cure rate and the curative effect in treatment of mixed hemorrhoids.

In order to provide a theoretical basis for the regulation of active ingredient, the terpenoids metabolic pathway and specific enzymes in Blumea balsamifera are investigated. Basing on transcriptome information, B. balsamifera terpenoids metabolic pathway was analyzed in KEGG data base. Four metabolic pathway of terpenoids were found in KEGG data base. They were terpenoid backbone biosynthesis, monoterpenoid biosynthesis, diterpenoid biosynthesis, sesquiterpenoid and triterpenoid biosynthesis, contained 103, 10, 29,59 genes, respectively. Through the analysis of the enzyme and product in the pathway, the result showed that there were 8 kinds of monoterpenes, 3 kinds of diterpenes, 3 kinds of triterpenes and sesquiterpenes. The mainly key enzymes were deoxyxylulose 5-phosphate synthase, HMG-CoA reductase and allyl transferase system. In B. balsamifera, there were relatively few monoterpenes synthetic enzymes, while the type of products was much more than other terpenes. This may be relate to the non-specific catalytic characteristic of monoterpene synthase. It is expected to improve the yield of terpenoids in B. balsamifera by analysis the pathways and regulation the key enzymes.

To better understand the biosynthetic pathway of flavonoids in Blumea balsamifera, and to increase the biosynthesis of flavone and flavonol amount, we carried out this research. Basing on transcriptome information, B. balsamifera flavonoids metabolic pathway was analyzed in KEGG data base. The result demonstrated that two metabolic pathways of flavonoids were found in KEGG data base. They were flavonoid biosynthesis pathway (No.ko00941) that contained 32 genes and flavone and flavonol biosynthesis pathway (No.ko00944) that contained 12 genes. Metabolic pathway of flavonoids in B. balsamifera was similar to that in other plants. Chalcone synthase (CHS) and Chalconeisomerase were much likely to be key enzymes on metabolic pathway of flavonoids in B. balsamifera. HCT was much relevant to biosynthesis of favones.

OBJECTIVE: To study the content of mineral elements and the principal components in Gastrodia elata. METHOD: Mineral elements were determined by ICP and the data was analyzed by SPSS. RESULT: K element has the highest content-and the average content was 15.31 g x kg(-1). The average content of N element was 8.99 g x kg(-1), followed by K element. The coefficient of variation of K and N was small, but the Mn was the biggest with 51.39%. The highly significant positive correlation was found among N, P and K . Three principal components were selected by principal components analysis to evaluate the quality of G. elata. P, B, N, K, Cu, Mn, Fe and Mg were the characteristic elements of G. elata. CONCLUSION: The content of K and N elements was higher and relatively stable. The variation of Mn content was biggest. The quality of G. elata in Guizhou and Yunnan was better from the perspective of mineral elements.

OBJECTIVE: Combination of different planting direction and layer were set to choose the best technology of cultivation of Gastrodia elata f. elata. METHODS: To improve the yield and quality of Gastrodia elata f. elata, randomized block design experiments were carried out to investigate the yield and quality, and to analyze their economic effectiveness in bionic wild cultivation. RESULTS: Length, width, thickness and weight of southern direction's Gastrodia elata f. elata developed better than the northeast direction. The three planting layer levels on growth effect of Gastrodia elata f. elata was the 3rd layer > the 2nd layer > the 1st layer. In six treatments, combination of southern direction-the 3rd layer was the best technology of cultivation of Gastrodia elata f. elata, which had the best growth condition, the highest yield significantly higher than other treatments, and the best economic benefits. CONCLUSION: Southern direction associated with the 3rd layer is the best combination to planting Gastrodia elata f. elata in bionic wild cultivation. The planting ways not only improve the yield and quality, but also save land.

OBJECTIVE: To provide reference in selecting premium provenance and improve the cultivation techniques of Polygonum multiflorum. METHODS: Field survey, routine field-observation and sampling fixed plant for analysis in lab were adopted. RESULTS: The growing adaptability of Polygonum multiflorum was very strong, which growed flourishly in the condition with adequate light, ample rainfall, rich heat and fertile soil; Along with the lower of latitude, the vegetative period was prolonged and reproductive stage was delayed, which prolonged the time of roots' nutrition acquisition. Time for root shoot ratio increasing continuously of low latitude germplasms was higher than that of higher latitude germplasms. CONCLUSION: Polygonum multiflorum germplasms have different biological characteristics because of different regions and habitats, which can provide useful reference for selecting premium provenance and adjusting measures to local conditions in different areas.

OBJECTIVE: To study the seed germination characteristic and optimal germination condition of wild Disporum cantoniense. METHODS: Used wild Disporum cantoniense seed as the test materials, the rate of water absorption of the seed was determined. The germination rates under different conditions, along a temperature gradient (15, 20, 25 and 30 degres C), in light or dark, on top or between wet filter papers, and keeping or removing the seed coat, were determined respectively using petri dish method. At the same time germination trends were observed. RESULTS: The thousand seed weight was 33.24 g, and the seed water-absorbing reached saturation pot after soaking for 30 h. Higher germination rates were respectively recorded at 25 degrees C, between filter papers, and in dark after 24 h soaking in the pretreatment solution. CONCLUSION: The optimal condition for the germination of the seed of wild Disporum cantoniense is as follow: keeping testa, seed soaking for 24 h in seed germination agent and being incubated between wet filter papers in dark at 25 degrees C.

OBJECTIVE: To study the absorption and accumulation of N, P and K in Ophiopgon japonicus. METHOD: The contents of N, P, K and trace element were determined respectively by using the kjeldathl method digested with H2SO4 + H2O2, ammonium vanadstemolybdate chromoscopy, flame spectrometry and atomic absorption spectrophotometry. RESULT: The contents of N and K were the highest, and that of P was relatively lower O. japonicus. The changing pattern of N was low-high-low in the growth and development period. The accumulative speed of N had two relatively quicker and two relatively slower phases. The content of N is higher in nutritive organs; The changing pattern of P was similar to that of N, while the content of P is higher in leaves and nutritive roots at early stage of growth and development. It was high in root tuber during harvesting stage, and the accumulative quantity in the plant was increased gradually. The level of K was high in early stage and low in later stage of growth. The content of K was relatively higher in leaves and nutritive roots at early stage, and that in root tuber was slightly lower than the leaves but higher than that the nutritive roots from February to March. The accumulating quantity slightly increased in the plant. CONCLUSION: The application quantity of N should be increased gradually after transplant, stopped in autumn, and used again in early spring. Phosphate fertilizer is needed in autumn and winter, while large amount of potassium fertilizer shoule be used in winter tine.
