Type 2 diabetes mellitus (T2DM) is a common chronic metabolic disorder,it results from an interaction of environmental as well as genetic factors.There were several kinds of oral antidiabetic drugs (OADs),including biguanides,sulfonylureas,thiazolidinediones,and meglitinides,etc.Several genes have been identified to be associated with disease development and therapeutic outcomes.Inter-individual variations in the human genome affect both,risk of T2DM development and personalized response to identical drug therapies.Pharmacogenomics approaches focus on single nucleotide polymorphisms and their influence on individual drug response,efficacy and toxicity.Therefore,pharmacogenomics in T2DM is of great importance towards precision medicine which will greatly improve the efficacy of diabetes treatment.In this paper,antidiabetic drugs and related gene polymorphism researches are reviewed.

Objective To evaluate the use of the kite flap (als o known as subcutaneous pedicled V-Y advancement flap)for the repair of moderate -sized anterior lamellar skin defects of eyelid. Methods Since 1994, kite flaps have been used to repair anterior lamellar skin defects of eyelids in 14 patients. Six patients were male and eight female, with a mean age of 43 years (range 15-64 years). The diameter of the largest defect reache d 1/3 length of the eyelid. The flaps were designed adjacent to the defects and the incision line corresponding to natural winkle lines on the eyelid. We underm ined the flap under the orbicular muscle, and advanced the flap to cover the def ect. The incisions were closed with 7-0 suture. Results After operation, all flaps survived with primary healing. Follow-up for 3 to 12 months showed that all cases had achieved satisfactory cosmetic effects without secondary deformity. Conclusions It is a simple, safe, an d reliable method to use kite flap for the repair of moderate-sized anterior la mellar eyelid skin defects that are too large to achieve primary approximation. Because kite-flap covers the defect through a direct advancement way without ro tation and twist, there are no dog-ear deformitys present at the pedical area a nd the repaired area looks smoothly. Because of its widely based muscle pedicle which incorporates venous and lymphatic drainage over most of its length, the un desirable pigment deposition is avoided.

Chinese materia medica (CMM) has double complexity in bioactive ingredient and its mechanism. It is difficult to explain by the modern biomedicine theory So it seriously restricts the modernization of CMM The modern CMM should have the high quality standard to meet the needs of international standard It can be guaranteed by spreading the GAP for Chinese medicinal materials and GMP for standard production The mechanism depends on using the DNA microarray to set up “the gene expression difference chart”, to study on the combination of CMM and gene expression difference chart Meanwhile, we can establish a totally new method of screening modern CMM based on the gene expression difference chart, it can really make the modernization and internationalization of CMM

Objective To explore the effects of finasteride therapy on the expressions of heat shock protein 70(HSP70)mRNA,heat shock protein 22 (HSP22)mRNA,tumor necrosis factor-alpha (TNF-a),interleukins-1β (IL-1β) in elderly patients with benign prostatic hyperplasia (BPH).Methods Totally 68 elderly men patients with BPH were divided into two groups:regular treatment group (n=34) and finasteride treatment group(n=34),30 elderly men patients without BPH were as control group.The blood samples of patients after treatment were collected for the detections of HSP70mRNA and HSP22mRNA with RT-PCR,meanwhile,the levels of TNF-α,IL-1β were measured by radioimmunoassay (RIA).Effect of treatment was evaluated in accordance with International Prostate Symptom Score (IPSS).Results The expressions of HSP70 mRNA and HSP22 mRNA,TNF-α,IL-1β in BPH patients were higher in finasteride group than in control group (P＜0.01).After 12 weeks therapy,the levels of HSP70mRNA,HSP22mRNA,TNF-α and IL-1β were decreased in finasteride group (P＜0.01 or P＜0.05) but no significantly difference in regular treatment group.Compared with regular treatment group,the expressions of HSP70 mRNA,HSP22mRNA and TNF-α were reduced in the finasteride group after treatment (P＜0.01 or P＜0.05),IPSS was more improved (P＜0.05),but IL-1β was not distingished between two groups (P＞0.05).IPSS was positively related to the levels of HSP70 mRNA,HSP22 mRNA,TNF-α and IL1β (r=0.4251,0.4976,0.4562,0.3627,P＜0.01 or P＜0.05).Conclusions The occurrence and development of BPH are closely related with immunoinflammatory factors.Finasteride not only affects the levels of dihydrotestosterone but also can inhibit the expression of immunoinflammatory factors to improve symptom by reducing the volume of benign prostatic hyperplasia.
