Free fatty acids(FFAs) provide an important energy source and also act as signaling molecules.Medium to long-chain free fatty acids can activate the intracellular signal pathways in the pancreatic ?-cells and play a role in regulating insulin secretion as an extracellular signal molecular via binding to the FFA receptor G protein-coupled receptor 40(GPR40). Furthermore,GPR40 is associated with several biological effects including cell proliferation and antiapoptosis of nerve cells.GPR40 act an important role in the connection of obesity and diabetes or cancers.GPR40 will probably become a novel kind of antidiabetic and anticancer drugs.

Objective To investigate the expression levels of microRNA(miR)-125b, miR-29a and miR-155-5p in ce?rebrospinal fluid (CSF) and plasma from the patients with tuberculous meningitis and their clinic significance. Methods Cerebrospinal fluid and plasma samples were collected from 20 patients with tuberculous meningitis (tuberculous meningitis group) and 20 patients suffered from primary headache (control group). The total RNAs were extracted.The levels of miR-125b, miR-29a and miR-155-5p were determined by real-time quantitative PCR (q-PCR). Results Levels of miR-29a and miR-125b in both CSF and plasma of patients in tuberculous meningitis group were significantly higher than those in pa?tients from control group with statistical significance (P<0.01). Mean time, the level of miR-155-5p in plasma but not in CSF of patients in tuberculous meningitis group was higher than those in control group with statistical significance ( P<0.01). Conclusion Expression of miR-125b, miR-29a and miR-155-5p may participate in regulating the occurrence and development of tuberculous meningitis. And miR-125b and miR-29a may be used as potential biomarkers for diagnosing tu?berculous meningitis.

OBJECTIVE:To investigate the role of clinical pharmacists in the therapy for acute exacerbation of chronic obstruc-tive pulmonary diseases (AECOPD) complicated with pulmonary infection. METHODS:Clinical pharmacists participated in the therapy for a case of acute exacerbation of AECOPD complicated with pulmonary infection.

RESULTS:The physicians adopted clinical pharmacist’s suggestions. No ADR was found during treatment,and the patients transferred to ordinary ward after the disease condition had been controlled. CONCLU-SIONS:The participating of clinical pharmacists in pharmaceutical care can promote rational drug use in the clinic and guarantee the safety of drug use.

Objective To make a comparative assessment on both the therapeutic effects and side effects between percutaenous lauromacrogol injection therapy(PLIT) and percutaenous ethanol injection therapy(PEIT) for simple hepatic or renal cyst.Methods In group A,55 patients with simple hepatic or renal cysts underwent ultrasound-guided aspiration and successive PLIT.The intra-operative side effects were investigated and the therapeutic effects assessment by using ultrasonography was conducted 3 months after the treatment.In group B,60 patients with simple hepatic or renal cysts had received ultrasound-guided aspiration and PEIT sometime before.The intra-operative side effects and therapeutic effects on the thirdmonth ultrasonography were independently reviewed according to their case records.Results In group A,3 patients(5.5 ％) expressed slight discomfort but not pain while receiving lauromacrogol injection.Follow-up ultrasound examination at the end of third month demonstrated the cysts in 43 patients completely regressed,while cysts in rest 12 patients shrank over 50 ％ in size,showing the overall response rate(ORR) and completely cure rate(CCR) were 100％ (55/55) and 78.2％ (43/55) for PLIT respectively.In group B,12 patients(20％) suffered from slight to moderate irritating pain or drunk performance.The third-month ultrasound examination disclosed that cysts in 47 patients completely vanished,and cysts in the other 13patients shrank more than a half,indicating the ORR and CCR were 100％ (60/60) and 78.3 ％ (47/60) for PEIT respectively.Conclusions Although their therapeutic efficacy are perfectly similar,PLIT is much more superior to PEIT in term of less and minor side effects.

NIT-1 cells were exposed to various concentrations of glucose for 24,48,and 72 hours.The content of triglyceride in NIT-1 cells increased in dose-and time-dependent manners (P ＜ 0.05).Long-term exposure of NIT-1 cells to high glucose concentrations caused an inverse "v"-like induction of HSL mRNA and protein expressions,which increased from beginning,and then decreased,along with similar changes of lipolysis.These results suggest that the adaptation of HSL may play an important role in regulating the intracellular triglyceride pool and the development of glucolipotoxicity in pancreatic β cells.
