Objective To discuss the effect of self-clotting cutter radiofrequency ablation in curing the hysteromyoma. Methods 96 patients with hysteromyoma were selected. Their hysteromyomas were cured by self-clotting cutter radiofrequency ablation through virgina under the direction of B-ultrasound. Then they were followed up for one month, three months and six months after the operation. Results Six months after the treatment,42.71% of the patients were eumenorrhea,44.79% of the patients' menstrual bleeding volumes were few, 12.5% has no change. The cure rate of anaemia was 100%. 1 month,3 months ,6 months after the treatment, the bulks of uterus and myoma were reduced,and the myoma reduced most after six months. 35.42% of the patients were cured,47.92% had remarkable effect, 15.6% had effect, 1.04% had no effect. Total effective rate was 98.72%. Conclusion The clinical effect of self-clotting cutter radiofrequency ablation in curing the hysteromyoma was satisfactory. It was a minimally invasive technique which could keep the integrality of uterus and it was rapid recovery,effective and safe,and easy to operate.

microRNAs (miRNAs) are short non-protein-coding RNAs,which play important roles in the cell proliferation,differentiation,apoptosis,as well as activation of oncogenic and antioncogenic signals.Researches show that the abnormal expressions of miRNAs are closely related to the tumorigenesis,histological type,diagnosis,treatment and prognosis of lung cancer.So miRNAs may be the most potential and promising therapeutic targets for lung cancer.

Objective To determine the expression of cancer stem cell markers, CD133, CD44 and OCT-4, in small cell lung cancer cell line NCI-H82 and confirm the specific markers. Methods NCI-H82 cells were cultured, and the expressions of markers (CD133, CD44 and OCT-4) were detected by immunofluorescence staining. The immunohistochemistry was performed to detect the expressions of CD133, CD44 and OCT-4 in 79 tissues with small cell lung cancer. Results In NCI-H82 cells, the florescence was positive in CD133 and CD44 and negative in OCT-4. In the tissues, the expression of CD133 and CD 44 was related with tumor size, lymph node metastasis and clinical stage (P< 0.05), while OCT-4 was negative expression. Conclusion CD133 and CD44 might be the cancer stem cell markers of small cell lung cancer, which maybe have clinical significance on diagnosis and treatment.

Objective To observe the efficacy of imatinib on the treatment of bcr-abl positive essential thrombocythemia (ET). Methods A case of bcr-abl positive ET resistant to hydroxyurea (HU) treating with imatinib (200～400 mg/d) was reported and related literatures were reviewed. Results A case of bcr-abl positive ET was initially treated with 1.5～2.0 g/d HU, the platelet count decreased to 562x109/L after 4 weeks; however, the platelet count increased to (1020～1330)×109/L treating with same dose of HU 16 months later. With the elevation of HU to 3.0 g/d, platelet count was still high(1290～1780)x109/L companied with the very low white blood cell count(0.3～0.9)×109/L. While treating with imatinib (400 mg/d) for 1 month,the platelet count decreased to 390×109/L and white blood cell count was 0.5×109/L; Furthermore, treating with 200×300 mg/d of imatinib, the platelet and white blood cell count recovered in normal after 1 month,and bcr-abl fusion gene negative 2 months later. Conclusion Imatinib may be the effective targeting drug for the bcr-abl positive ET, and the bcr-abl positive ET is sensitive to low dose imatinib.

CONCLUSIONS:The established HPLC is suitable for the dissolution determination of Ramelteon tablet;the dissolution profiles of the self-made and original preparations are similar,it preliminary indicates the prescription and technological rationality of self-made preparation.

Objective:To study the solubility of repaglinide in meglumine aqueous solution. Methods: In order to increase the solubility of repaglinide, meglumine was used to react with repaglinide and obtain a molecular complex. The structure and composition of meglumine-repaglinide complex was analyzed by DSC, HPLC and HPLC-MS. Results:Meglumine and repaglinide formed a molecu-lar complex, and their best molar ratio was 1 ∶1. With the concentration increase of meglumine, the solubility of repaglinide also in-creased. The stability of molecular complexes decreased with the temperature increase. Conclusion:Meglumine plays a good role in the solubilization of repaglinide.

Angelicae Sinensis Radix (ASR) is the root of Angelica sinensis which is a fragrant and perennial herb native to China,Japan,and Korea.In traditional Chinese medicine (TCM),the plant is useful for replenishing and invigorating blood,relieving pain,and moistening the intestines,resulting in its application for the treatment of menstrual disorders,and as an emollient and laxative for chronic constipation of the aged and debilitated.An in-depth review of the literature brings to light a great number of chemical constituents that have been isolated from ASR as well as both preclinical (in vivo and in vitro) and clinical studies,which over the years,have sought to investigate the medicinal relevance of some of these phytoconstituents and/or extract(s) prepared from ASR.The purpose of this review is therefore to present some major pharmacological and pharmacokinetic research findings on some selected phytoconstituents of ASR with emphasis on the current trends in terms of research techniques or design.This review would also provide a wealth of information for users/practitioners of TCM regarding the use of ASR or its products for maximum efficiency and minimal toxicity or side effects.

OBJECTIVE:To provide reference for promoting the priority use of essential medicines. METHODS:The use amount ratio of essential medicines in 2 third-level grade-A hospitals in Beijing from 2011 to 2013 was statistically investigated. And the literatures related to policies of essential medicines and application were retrieved for in-depth analysis. RESULTS:The use amount ratios of essential medicines in the outpatient and emergency departments in Beijing Hospital of Ministry of Health from 2011 to 2013 were respectively 24.04%,23.10% and 22.76%;and the use amount ratios of essential medicines of inpatients were respectively 16.56%,14.52% and 12.04%. The use amount ratios of essential medicines in the outpatient and emergency depart-ments in Beijing Friendship Hospital(a pilot hospitals of cancelling drug addition medical reform)in the 3 years were respectively 21.59%,19.85% and 22.93%;the use amount ratios of essential medicines of inpatients were respectively 17.70%,17.62% and 15.89%. The use amount ratios of essential medicines did not meet 25%-30% of the requirements. CONCLUSIONS:Cancelling the drug addition and adjusting the types and quantity of essential medicine list had no obvious effects on the use amount ratios of gen-eral third-level grade-A hospitals. It is suggested to promote the priority use of essential medicines by systems of medical insurance total amount prepayment,single disease payment or diagnosis related groups-based prepayment and the free policy of essential medi-cines,rather than administrative order.

Objective To investigate and determine the dietary intake level and food source of elements in Kashin-Beck disease(KBD) and non-endemic KBD areas in parts of Aba Autonomous Prefecture , Sichuan Province. Methods Three KBD villages were selected from each county including the counties of Songpan , Jiuzhaigou and Ruoergai in Aba Autonomous Prefecture with multi stage random sampling method in 2010 , and 122 KBD patients who were diagnosed at county-level or higher-level hospitals were selected from villages. One non-KBD village was selected randomly from each county and 43 controls without KBD or other bone and joint disease were selected in proportion to the number of investigated KBD patients. Dietary intake of each object was recorded 24 hours before the survey using a 24 hour dietary survey method and intake of each kind of food(cooked food) was recorded. Three day dietary intake of each surveyed object was recorded in continuous and the average value was calculated. The local resident representative food samples were collected and 20 kinds of elements in these samples were determined with inductively coupled plasma mass spectrometry ( ICP-MS ) and inductively coupled plasma atomic emission spectrometry(ICP-AES), and daily elements intake was calculated and compared with the relevant intake standards. Results Daily intakes of vegetables and meat were 126.72, 28.25 g, respectively, in patients with KBD. More than 3 times of brick tea was drank by KBD patients than non-KBD people (P<0.05). Per capita daily intakes of Ca, Fe, Mg, K, Na, Zn, I, Cu and Co were less than recommended nutrient intake or allowable daily intake in both groups. More than 80% patients with KBD overtook more Al and Pb than tolerable upper intake levels. Conclusion There is a single dietary structure and a serious shortage of a variety of essential elements intake in parts of Aba Autonomous Prefecture, and the dietary intake level of elements is different between two groups.
