[Objectives] To survey the current using situation and price distribution of pharmaceutical preparations in medical institutions of Sichuan Province,to provide basis for pricing the pharmaceutical preparations in medical institutions. [Methods] From June to September2016,15 sample hospitals were selected from Ⅱ-B class,Ⅱ-A class,Ⅲ-B class and Ⅲ-A class hospitals,and questionnaire survey was adopted to survey the current situation of pharmaceutical preparations in medical institutions,and 24 effective questionnaires were collected.SPASS17. 0 software was used to analyze the data of the questionnaires. [Results]The pharmaceutical preparations in medical institutions between 10 and 15 yuan accounted for 35%,which was the biggest percentage. The second was between 5 and 10 yuan,which accounted for 25%. [Conclusions] Most of the pharmaceutical preparations in medical institutions of Sichuan Province are in the low price,and floating rate price adjustment mechanism is suggested.

[Objectives] To develop a method for separation and purification of acetophenones from Cynanchum bengei Decne root bark by combination of silica gel and high-speed counter-current chromatography( HSCCC). [Methods]The crude extract of Cynanchum bengei Decne root bark was separated by silica gel column chromatography,and parts A and B containing acetophenones were obtained. Then,parts A and B were separated by HSCCC with a two-phase solvent system composed of petroleum ether-ethyl acetate-methanol-water( 4∶ 6∶ 4. 5∶ 5. 5 and4∶ 6 ∶ 3 ∶ 7, V/V), respectively. [Results] From 260 mg of part A, four compounds with p-dihydroxybenzene 3. 9 mg(Ⅰ),4-hydroxyacetophenone 17. 1 mg( Ⅱ),2,5-di-hydroxyacetophenone 13. 3 mg(Ⅲ) and 2,4-dihydroxyaceto-phenone 21. 0 mg(Ⅳ) were obtained. And from 300 mg of part B,136 mg of Radix Cynanchi Bungei benzophenone(Ⅴ) was obtained. The purity of compounds determined by HPLC was 97. 0%,96. 6%,99. 2%,99. 7%,99. 5%,respectively. [Conclusions] The established method is simple and efficient. It can be used for separation of acetophenones from Cynanchum bengei Decne root bark and has better practical value,which could provide a reference basis for development and utilization of Cynanchum bengei Decne root bark.
[Objectives]To optimize the extraction technology of total flavonoids from Pueraria lobata( Willd.) Ohwi. [Methods]The ultraviolet-visible spectrophotometry was used to determine the content of total flavonoids in Pueraria lobata( Willd.) Ohwi. With the puerarin as index,the reflux extraction and single factor test were employed to investigate the effects of temperature,time,ethanol concentration and solid-liquid ratio on the content of total flavonoids in Pueraria lobata( Willd.) Ohwi,respectively. Under the optimal extraction technology,the content of total flavonoids in Pueraria lobata( Willd.) Ohwi at different altitudes was determined.[Results] The optimum extraction process was as follows: 70%ethanol; solid-liquid ratio of 1∶ 30; 1 h reflux extraction. Under these conditions,the extraction rate of flavonoids in Pueraria lobata( Willd.) Ohwi was 11. 48%,the total flavonoids content of different kudzu parts was in the order of roots > stems > leaves,and the total flavonoids content of the sample at about an altitude of 1000 m was significantly higher than at the altitudes of 1400 m and 1700 m.[Conclusions]It was suggested that the Pueraria lobata( Willd.) Ohwi should not be cultivated as medicinal plant in too high mountains,and the stems and leaves of Pueraria lobata( Willd.) Ohwi could be used as raw materials for extracting total flavonoids.

[Objectives] To explore the effect of mouth outside bonding screw fixation and inside bonding fixation in implanting the prosthesis( crown or bridge) on the health of surrounding tissues,to provide a certain reference for the selection of fixation methods for clinically implanting the prosthesis. [Methods]160 cases of patients needing implanting the prosthesis due to dental arch deficiency were selected. They had excellent alveolar bone. They did not smoke,had no diabetes,and their bone tissue healing was at the early stage. They were randomly divided into A and B groups,80 cases in each group. Group A: the mouth inside and abutment of prosthesis was bonded to a single abutment crown or a single abutment bridge; the bonder on the surface of prosthesis was completely removed and then moved into the implant,and fixed with central retaining screw,this group was called " mouth outside bonding group". Group B: the abutment was located in the implant and fixed using central retaining screw,then the prosthesis( crown or bridge) was bonded to the abutment,the bonder on the surface of prosthesis was removed,and this group was called mouth " mouth inside bonding group". The health condition was compared between two fixing methods for the surrounding tissues of the implant in 24-36 months after restoration. [Results] Group A: the surrounding tissues of the implants for 126 teeth of 80 patients were healthy without occurrence of peripheral inflammation; Group B: in the implants of 112 teeth of 80 patients,7 teeth suffered the peripheral inflammation. Dental implant examination found that there was residue of bonder in the bonding of prosthesis and abutment,3 teeth exfoliated,and 4 teeth were restored after treatment. Through the X2 test,there was significant difference between Group A and Group B( P < 0. 05). [Conclusions] Implant-supported denture often adopts the mouth inside bonding. Since the bonder can not be removed completely,its residue will remain in gingival trough and stimulate the surrounding tissues of the implant and bring about the inflammatory reaction,and even lead to exfoliation of the implant; the mouth inside and abutment of prosthesis was bonded to a single abutment crown or a single abutment bridge,the bonder on the surface of prosthesis was completely removed and then moved into the implant,and fixed with central retaining screw. This method is an effective method for preventing the peripheral inflammation and increasing the success rate of dental implant.
[Objectives] To study the expression of Med 19 protein in tongue cancer and its significance. [Methods] Immunohistochemical method was used to detect the expression of Med 19 protein in tongue cancer tissue and paracancerous tissue. [Results]The expression of Med19 protein in tongue cancer tissue was higher than paracancerous tissue and normal tissue. The expression of Med 19 protein was related to the tumor lymph node metastasis. However,there was no significant difference in sex,age,Tumor Node Metastasis( TNM),and differentiation degree. [Conclusions] Med 19 protein participates in incidence and development of tongue cancer and may become diagnostic indicator and therapeutic target for tongue cancer.
