Objective:To measure the concentration of free fatty acids(FFAs) and analyse its associations with correlative factors in patients with polycystic ovarian syndrome(PCOS).Methods:11 obese and 28 non-obese women with PCOS and 21 age-matched healthy women were recruited.Serum concentration of FFAs,free testosterone,androstenedione,total testosterone,sex hormone binding globulin,TC,TG,HDL-c,LDL-c,fasting plasma glucose (FPG),2-hours post prandial glucose (PPG),fasting insulin(FINS) and insulin sensitivity (with two-step hyperinsulinemic euglycemic clamp technique) were measured.Results:There was no significant difference in serum FFAs level between obese and non-obese women with PCOS,while both groups showed higher serum concentration of FFAs than controls( P

Dorsal-ventral axis formation is one of the earliest and the most important steps of patterning formation during early embryogenesis.The molecular basis of dorsoventral axis formation reflects the fundamental issues of orchestrated cell proliferation and differentiation.Wildly speculated since the Renaissance,the effort of deciphering the mechanisms of dorsal-ventral axis formation has contributed significantly to our current understanding of disease pathogenesis.Here,we focused our discussion on the recent discovery of the convergence of dorsal and ventral signaling pathways during early embryogenesis and its implications in cancer biology and beyond.

MicroRNA,which is found in recent years,is a class of small noncoding RNAs of about 18-24 nucleotides in length,that can regulate gene expression.It induces mRNA degradation or inhibit translation of tagert genes mainly by complete or incomplete base pairing to the 3' untranslated region of tagert messenger RNAs.The application of microRNA biology technology provides new methods to the research of multiple diseases,and can further elucidate its occurrence,development mechanism.In this paper,microRNA biology-related researches are introduced and miR-125 in a variety of diseases is reviewed.

The recent development of process analytical chemistry(PAC) in the past years is reviewed. The content includes process measurement, sensor, chemometrics etc. The future of PAC is also discussed. 62 references are cited

Objective To observe the efficacy and acute toxicity in non-myeloablative low-dose tatal body irradiation. Methods From January 2006 to January 2008, 27 cases of hematopoietic stem cell transplantation patients received non-myeloablative pretreatment program involving low-dose whole body irradiation. Pretreatment program: the total dose of TBI was 2 Gy, once completely. According to primary disease, physical condition, age, organ function and HAL coincide situation, the patients received different chemotherapy, including FUL, CTX, Ara-C, melphalan and so on. To prevent the graft-versus-host disease (GVHD), CSA/MMF was used. Results Hematopeietic reconstruction: the peripheral blood WBC in all 27 cases reduced to (0.05-0.9) × 109/L in 4 to 8 days, with the neutrophil count > 0.5 × 109/L in 8 to 22 days (median + 10.5 days), the platelet count > 30 × 109/L in 11 to 28 days (median + 14.5 days). The transplant rate was 85.2% (23/27). The fever rate was 65% and the infection rate was 37% (10/27). Hemorrhagic cystitis,hepatic veno-occlusive disease (HVOD), and other complications did not occurred. 4 cases developed aGVHD (15 %) and 5 cases developed cGVHD (19 %) out of 27 cases. Follow-up 3 to 22 months, 21 eases are still alive (77.8%). Conclusions Pretreatment with low-dose whole body irradiation of non-myeloablative hematopeietic stem cell transplantation proved to be simple and safe with fewer complications and broad indications. Program of TBI with total dose of 2 Gy (once completely) is a safe, less toxic and effective method. It could achieve the effectiveness of immune suppression.

It is of great importance to have a correct understanding of what is meant by governmental purchasiug and the system of governmental purchasing. The authors first expound the connotation and extension, characteristics and forms of governmental purchasing and the significance and necessity of centralized drug purchasing. Then they focus their discussion on the specific procedures of centralized drug purchasing. Finally they point out that it is imperative to seek unity of thinking, standardize operations, adopt institutionalized means of management, and make a really good job of centralized drug purchasing.

In post-trial follow-up of DCCT,UKPDS and Steno-2 studies,sustained beneficial effects on the risk reductions for microvascular and macrovascular complications has been observed in previous intensive treatment group,suggesting that patients with diabetes benefit mostly from early intensive blood glucose control.On the other hand,intensive glucose lowering therapy has been shown to increase the risk of all cause mortality in high-risk patients with type 2 diabetes in ACCORD study.Therefore,the target of blood glucose control should be individualized for each diabetic patient.Not only intensive glucose lowering therapy but also avoidance of hypoglycemia during therapy should be highly considered.

Objective To establish the quality standard for Complex Prescription Kudouzi Capsules.Methods TLC was employed to identify Crataegus pinnatifida Bge.、Cassia obtusifolia L.and sophora alopecuroides L..The content of chrysophanol in Cassia obtusifolia L.was determined by HPLC.Results Spots obtained from the test solutions had the same color in reference solution and medical material in the same location,and the blank solution had no interference.The linear range of chrysophanol was 0.028 4 ～ 0.908 8 ?g,r =0.999 7(n =6),and the average recovery was 99.97%.Conclusion The characteristic of identification by TLC was highly specific,HPLC is accurate and reproducible,and they can be used effectively for the quality control of Complex Prescription Kudouzi Capsules.
