AIM To study the effects of propofol on membrane fluidity and intracellular free Ca 2+ concentration ([Ca 2+ ] i ) in PC12 cells and discuss its relevant mechanism. METHODS PC12 cell lines were divided into seven groups: control, solvent and propofols(1,3,10,30,100 mg?L -1 ). Fluorescence depolarization method was used to measure dynamically microviscosity in PC12 cells and [Ca 2+ ] i was detected using calcium fluorescentprobe Fluo 3/AM and a laser scanning confocal microscope. RESULTS ①Acute administration of various doses of propofol induced a significant decrease of microviscosity in PC12 cells dose dependenty. ② Solvent, propofol at dose of 10 mg?L -1 had no effect on [Ca 2+ ] i in PC12 cells, however, after 30 and 100 mg?L -1 administration, [Ca 2+ ] i increased markedly at 20~30 seconds (increase percentage were 119% and 140% respectively) and then recovered to their pre administration levels within 50 seconds. CONCLUSION The propofol can significantly increase membrane fluidity in PC12 cells in a dose dependent manner and elevate [Ca 2+ ] i in PC12 cells at doses of 30 and 100 mg?L -1 . These changes are consistent with each other and related closely with anesthetic effect of propofol.

AIM: To study the effects of propofol on plasma membrane fluidity in PC12 cells and liposome,and its relevant mechanism. METHODS: Fluorescence depolarization method was used to measure values of fluorescence anisotropy, fluorescence polarization as well as microviscosity in PC12 cells and microviscosity in liposome continuously for 30 min. RESULTS: Propofol induced a significant decrease of fluorescence anisotropy, fluorescence polarization as well as microviscosity in PC12 cells, particularly in the first 5 min. After 5 min, the values of anisotropy were remained lower levels. Although propofol at concentration of 1 mg?L -1 had no effects on microviscosity in liposome, porpofol at concentration of 10 mg?L -1 and 100 mg?L -1 significantly decreased microviscosity in liposome. CONCLUTION: Propofol can significantly increase membrane fluidity in PC12 cells and liposome in a concertration dependent manner, and the anesthetic effect of propofol may be resulted from changes of membrane fluidity and structure of neurocyte.

BACKGROUNDTo observe the efficacy and safety of navelbine (NVB) combined with ifosfamide (IFO) and cisplatin (DDP) (NIP regimen) and IFO plus DDP (IP regimen) for advanced non-small cell lung cancer (NSCLC).
METHODSOne hundred and twenty patients with advanced NSCLC pathologically proved were randomly divided into group A (NIP regimen, n=60) and group B (IP regimen, n=60).
RESULTSIn group A, 58 patients were evaluable. The response rates were 58.62%(34/58), 65.58%(17/26) and 53.12% (17/32) in whole group, untreated patients, and retreated patients, respectively. The median duration of survival was 11.3 months. One-year survival rate was 40.0%. In group B, 59 patients could be evaluated. The response rates were 40.68%(24/59), 63.33%(19/30) and 17.24%(5/29) in whole group, untreated patients, and retreated patients, respectively. The median duration of survival was 9 months and 1-year survival rate was 36.7%. There was no significant difference in objective response rate among all the patients and the patients with no prior treatment between the two groups ( P > 0.05, P > 0.05). However, among retreated patients, the response rate in group A was remarkably higher than that in group B ( P < 0.05). The main dose limiting toxicity was myelosuppression. Leukopenia at grade III+IV was significantly higher in the NIP arm than in the IP arm ( P < 0.05).
CONCLUSIONSNIP yields a higher response rate than IP does in retreated patients, with acceptable toxicity, which can be the first line regimen in the retreatment of advanced NSCLC. IP regimen showes a similar response rate and less toxicity in initial patients, compared with NIP regimen, so it might be considered a relevant regimen in initial patients with advanced NSCLC.

OBJECTIVETo explore the effect of microRNA-30a-5p (miRNA-30a-5p) on the biological behavior of human hepatoma cells.
METHODSThe liver cancer cell line SMCC-7721 cells and the normal liver cell line L02 cells (control) were transiently transfected with miRNA-30a-5p mimics and an miRNA-30a-5p inhibitor by Lipofectamine 2000 (Life Technologies). miR-30a-5p mRNA expression was detected by quantitative real-time (q)PCR. Cell proliferation was evaluated using the Cell Counting Kit-8 (CCK-8) assay and apoptosis was assessed by flow cytometry.Invasion and migration were measured by transwell chamber assays. The SMCC-7721 cells was injected subcutaneously into nude mice to establish a tumor animal model.
RESULTSThe SMCC-7721 cells transfected with miRNA-30a-5p mimics showed significantly higher miRNA-30a-5p mRNA expression than the non-transfected SMCC-7721 cells and the transfected control L02 cells (P<0.01). The miRNA-30a-5p mRNA expression was significantly lower in the SMCC-7721 cells transfected with the miRNA-30a-5p inhibitor than the non-transfected SMCC-7721 cells the control L02 cells (P<0.01). The overexpression of miRNA-30a-5p inhibited the viability, colony formation rate, and invasion and migration abilities, as shown in the cells transfected with the miRNA-30a-5p mimics (P<0.05); in addition, the miRNA-30a-5p promoted proliferation of cells (P<0.05), as shown by more S phase cells detected by flow cytometry. SMCC-7122 cells transfected with miRNA-30a-5p mimics produced tumors with significantly higher average weight than tumors produced by SMCC-7122 cells that were untransfected or transfected with empty vector (both P<0.01).
CONCLUSIONOverexpression ofmiR-30a-5p had an inhibitory effect on cell proliferation, induced apoptosis, increased the number of cells in S phase, and markedly inhibited invasion and migration of SMCC-7721 HCC cells in vitro and in vivo.

OBJECTIVESTo observe the synthesis of Toll-like receptor (TLR) 4 protein and its mRNA expression in Kupffer cells (KCs) and evaluate the role of TLR 4 in liver injury to rats through alcohol-induced liver disease.
METHODSTwenty-eight Wistar rats were divided into two groups: ethanol-fed (group E) and control (group C). Group E rats were given ethanol at a dose of 5 - 12 g x kg(-1) x d(-1), while group C received dextrose. Animals from both groups were killed at 4 and 8 weeks. The KCs were isolated and synthesis of TLR 4 protein was determined by laser scanning confocal microscopy. TLR 4 mRNA expression in KCs was determined by reverse transcription polymerase chain reaction (RT-PCR) analysis. The levels of endotoxin, tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) in plasma were determined. Changes in liver pathology were observed.
RESULTSLaser scanning confocal microscopy showed that the intensity of fluorescence of TLR 4 protein in group E was stronger than group C. Ethanol administration led to a significant increase in TLR 4 mRNA expression in group E compared with group C (P < 0.05). The concentrations of plasma endotoxin, TNF-alpha and IL-6 were higher in group E than in group C (P < 0.05). Liver sections from rats in group E demonstrated marked pathological changes.
CONCLUSIONEthanol administration can lead to the synthesis of TLR 4 protein and its gene expression in KCs, indicating that TLR 4 may play a major role in the development of alcohol-induced liver injury.

Objective:To evaluate the association of HbA 1C level and variability with annual decline in glomerular filtration rate in elderly patients with type 2 diabetes. Methods:A total of 527 elderly type 2 diabetic patients with baseline estimated glomerular filtration rate(eGFR)≥60 mL·min -1·(1.73 m 2) -1 at the diabetes center of a tertiary hospital in Jiangsu province were included and followed up. The mean value and the variability of HbA 1C, including standard deviation(HbA 1C-SD), variation coefficient(HbA 1C-CV), and adjusted standard deviation(Adj-HbA 1C-SD) were calculated. According to the annual decreased rate of eGFR, the patients were divided into △eGFR>5% group and △eGFR≤5% group. Cox proportional risk regression model was used to evaluate the relationship between HbA 1C variability and the risk of decreased glomerular filtration rate. Results:With a mean follow-up time of 19 months, there were 176 patients whose △eGFR>5%. Compared with △eGFR≤5% group, the HbA 1C-mean and HbA 1C variability were significantly higher in △eGFR>5% group( P<0.05). Cox regression analysis showed that HbA 1C-mean, HbA 1C-SD, HbA 1C-CV, and Adj-HbA 1C-SD were significantly correlated with decreased glomerular filtration rate. After adjustment for age, gender, HbA 1C-mean, and other factors, only Adj-HbA 1C-SD was correlated with renal insufficiency [ HR=3.32(1.68-6.57)]. Conclusions:HbA 1C variability is independently associated with annual decline in glomerular filtration rate in elderly patients with type 2 diabetes. The Adj-HbA 1C-SD is the most sensitive indicator in predicting decreased glomerular filtration rate.
