Objective:To explore the effect of Gubi Decoction on serum related inflammatory factors and PI3K/Akt/mTOR signaling pathway in osteoarthritis model rats. Methods:Seventy SPF rats were randomly divided into the blank group, sham operation group, Glucosamine sulfate group, and the low, medium and high dose Gubi Decoction groups. Except the blank group and sham operation group, knee osteoarthritis animal models were prepared by the modified Hulth method in each group. On the 28th day after successful model preparation, the high, medium and low dose Gubi Decoction groups were given Gubi Decoction 24, 12 and 6 g/kg by gavage respectively; glucosamine sulfate group was given glucosamine sulfate tablet suspension 3 g/L by gavage, once a day for 28 days. The levels of TNF-α and IL-1β in serum were detected by ELISA. The gene expressions of PI3K, Akt and mTOR in cartilage tissue were detected by Real-PCR. The protein expressions of PI3K, Akt, p-PI3K, p-Akt and mTOR were detected by Western blot. Results:Compared with the model group, the knee joint diameter[(11.17 ± 1.81) mm, (11.60 ± 1.38) mm, (10.80 ± 1.17) mm vs. (12.57 ± 0.98) mm] of the rats in the glucosamine sulfate group and the medium and high dose Gubi Decoction groups significantly decreased ( P<0.05). The content of TNF-α [(111.43 ± 21.98) ng/L, (53.42 ± 13.25) ng/L vs. (157.89 ± 23.60) ng/L], IL-1β [(67.50 ± 18.44) ng/L, (48.22 ± 9.63) ng/L vs. (96.11 ± 14.85) ng/L] in the medium and high dose Gubi Decoction groups significantly decreased ( P<0.05), and the expression of PI3K (1.87 ± 0.17, 1.24 ± 0.49 vs. 2.19 ± 0.47), Akt (1.50 ± 0.51, 1.10 ± 0.32 vs. 2.68 ± 0.63), and mTOR (1.32 ± 0.54, 1.10 ± 0.33 vs. 2.94 ± 0.55) mRNA in the medium and high dose Gubi Decoction groups significantly decreased ( P<0.05). The expression of PI3K, Akt, p-PI3K, p-Akt in the low, medium and high dose Gubi Decoction groups significantly decreased ( P<0.05), and the expression of mTOR in the medium dose Gubi Decoction group significantly decreased ( P<0.05). Conclusion:Gubi Decoction can significantly reduce the level of inflammatory factors in the serum of osteoarthritis model rats, and its anti-inflammatory and analgesic effects may be related to PI3K/Akt/mTOR signaling pathway.

Vertical one-and-a-half syndrome (VOHS) is a rare ophthalmoplegia syndrome caused by unilateral thalamo-mesencephalic infarct. It is manifested as a conjugate upgaze palsy and a monocular paresis of downward gaze. Recognition of VOHS helps clinical localization. No cases of VOHS with photos or videos of ocular motility have been reported in China. Herein a case of VOHS caused by unilateral thalamo-mesencephalic infarct is reported, in order to improve awareness about the ocular sign.

Objective To observe the effects of leucine on adipogenesis in 3T3-L1 preadipocyte during and after differentiation, and to investigate possible mechanisms. Methods Respectively, 0.0 (control), 0.5, 1.0 and 2.0 mmol/L leucine was added in 3T3-L1 cells and cell proliferation was measured by MTT. Then, 3T3-L1 preadipocyte was induced to differentiate. Leucine was added during whole differentiation period, or after differentiation for 4 days. The cells were stained with Oil Red O dye to observe lipid droplet. The culture media were collected and used to determine glycerol contents. Meanwhile, protein expressions related to lypolytic enzymes, leptin signaling pathway were determined by Western blot. Results MTT result showed that cell viabilities were (100.00 ± 12.10)%, (102.73 ± 12.38)%, (103.94 ± 14.65)%, (108.70 ± 5.05)% in 0.0, 0.5, 1.0 and 2.0 mmol/L leucine groups, respectively, there were no significant differences in cell proliferation among 4 groups (F=1.07, P=0.383). When 0.0, 0.5, 1.0 and 2.0 mmol/L leucine was added during differentiation, the relative number of lipid droplet was 1.00 ± 0.06, 0.94±0.09, 0.82±0.08 and 0.79±0.04, respectively (F=11.74, P<0.001), and it was significantly lower in 1.0 and 2.0 mmol/L leucine groups than in control group(P=0.002 and P<0.001, respectively). There was no significant difference in lipid droplet when leucine was added after differentiation (F=0.16, P=0.924). When leucine was added during differentiation, the increment of glyceride contents in medium was (65.04 ± 11.75) , (71.45 ± 23.71), (79.37 ± 17.63) and (110.32 ± 25.36) μmol/L, respectively (F=2.92, P=0.100) . And it was significantly higher in 2.0 mmol/L leucine group (110.32 ± 25.36)μmol/L than in control group (65.04 ± 11.75)μmol/L(t=2.73, P=0.026). No significant difference of the increment of glyceride contents among 4 groups was observed when leucine was added after differentiation (F=0.80, P=0.528). Western blot results showed that leucine treatment during differentiation upregulated expression level of hormone-sensitive lipase phosphorylation (after 0.0 and 2.0 mmol/L leucine treatment,the protein levels were 1.00 ± 0.08 vs. 2.54 ± 0.27, P<0.001), and downregulated the protein expression levels of perilipin A, leptin and leptin-related pathway, such as leptin receptor, Janus kinase 2 and suppressor of cytokine signaling-3 (after 0.0 and 2.0 mmol/L leucine was added, the protein levels were(1.00 ± 0.03)vs.(0.31 ± 0.07),(1.00 ± 0.08)vs.(0.22±0.07),(1.00±0.07)vs.(0.21 ± 0.04),(1.00 ± 0.03)vs.(0.35 ± 0.05),(1.00 ± 0.06)vs.(0.34 ± 0.05), P<0.001). Leucine treatment after differentiation had no effects on these protein expressions (all P>0.05). Conclusion Leucine inhibits adipogenesis during 3T3-L1 preadipocyte differentiation by the regulation of lypolytic enzymes and leptin signaling pathway;however, leucine has no effect on adipogenesis when differentiation completed.

Objective To establish the screening platform of circulating tumor cells (CTCs) using acridine orange fluo?rescent (AO-F) dyeing method, and to apply it in the screening of peripheral blood CTCs in patients with kidney cancer. Methods Twenty-seven patients with metastatic renal cell carcinoma was included in this study. Primitive tumor cells and kidney cancer cell line 769-P were cultured with different concentrations of fetal bovine serum. Smears were prepared and observed under fluorescence microscopy. The percentage of AO-F positive staining of 769-P cells under 5 random sights was calculated. The sensitivity of AO-F staining to cells was evaluated. The 5 mL morning fasting venous blood was obtained from 10 subjects with healthy check-up. The 1×106 cell suspension was prepared. The logarithmic phase of renal tumor cells was used to prepare tube containing 500, 200, 100, 50 and 10 tumor cell suspension, which were mixed with 1×106 nucleated cells to establish CTCs model of renal cancer. AO-F staining method was used to detect the expression of AO-F positive cells. The correlation between expression of AO-F positive cells and clinical parameters was analyzed. Results The prima?ry cells and cell line 769-P showed similar bright color and morphological characteristics. The percentage of AO-F positive staining in 769-P cells was 93%±3%under 5 random sights. The recovery rates (%) of four groups (500, 200, 100 and 50 tu?mor cell suspension) were 10.2±3.8, 9.2±2.3, 10.8±2.6 and 10.5±1.9, respectively. There were no significant differences in recovery rates between four groups (P>0.05). The group of 10 tumor cell suspension could find AO-F positive staining cells occasionally. Zero case was positive in controls. Nine of 27 patients were positive and the rate was 33.33%. There were no significant statistical differences in AO-F positive rates between gender, age, tumor size, pathological pattern, Furhman stage, metastasis of lung and presence of tumor (P>0.05). Conclusion It is confirmed that the method of CTCs staining with AO-F, which has high specificity and reproducibility, is feasible to detect CTCs and worthy of being studied. There is a certain reference value to predict tumor recurrence and metastasis.

OBJECTIVETo evaluate the effects of compound whole grain-soybean on insulin resistance and serum adipocytokines levels in impared fasting glucose population.

METHODSAccording to inclusion and exclusion criteria, 163 cases of impared fasting glucose (IFG) Chinese Han population from the age of 40 to 75 years old, were screened from 12 community health centers of three main districts of Nanjing city by the multi-stage cluster and simple randomization method from March to September, 2008. The IFG subjects were randomly divided into the intervention group (87 individuals) and control group (76 individuals) by quasi-experimental design. The intervention group was provided with compound whole grain-soybean and health education, while only health education was provided for the control group. Body mass index (BMI), waist-to-hip ratio (WHR), lipid profiles, fasting blood glucose (FBG), fasting insulin (FINS) and homeostasis model assessment of insulin resistance (HOMA-IR), adipocytokines including leptin, lipocalin 2 (LCN-2) and adiponectin (ADP) levels were measured before and after the half a year intervention period. Chi square test was used to analyze the distribution differences. Two-sample t-test was used to compare the differences of the two groups before and after the half a year intervention period, and paired t-test was used to compare the differences between before and after intervention in the intervention group or control group. Wilcoxon rank sum test was used to compare the differences of all indexes between after and before dietary intervention.

RESULTSAfter dietary intervention for half a year on the IFG population, BMI ((24.87 ± 3.69) kg/m(2)), FBG((6.27 ± 0.24) mmol/L), FINS((7.14 ± 1.05) mU/L) , HOMA-IR (1.99 ± 0.31), leptin ((13.07 ± 2.22) µg /L), LCN-2 ((67.42 ± 18.20) µg/L) of intervention group were decreased significantly compared to the levels of BMI ((25.16 ± 4.07) kg/m(2)), FBG((6.40 ± 0.28) mmol/L), FINS ((7.32 ± 1.54) mU/L), HOMA-IR (2.08 ± 0.45), leptin ((13.43 ± 2.52) µg/L), LCN-2((74.87 ± 17.81) µg/L) before dietary intervention, t values were 4.48, 7.08, 2.05, 3.39, 3.28 and 6.36, respectively, and all P values were < 0.05, while ADP ((5.07 ± 1.51) mg/L) of intervention group after dietary intervention was increased significantly compared to the level of ADP ((4.92 ± 1.53) mg/L) before dietary intervention, t = -2.47 and P < 0.05. The medians (P25, P 75) of differences after and before dietary intervention in the intervention group were BMI (-0.25(-0.68, 0.02) kg/m(2)), FBG (-0.08 (-0.20, 0.00) mmol/L), FINS (-0.15(-0.32, 0.00) mU/L), HOMA-IR (-0.07(-0.12, -0.03)), leptin (-0.36(-0.77, 0.12) µg/L), LCN-2 (-5.85(-14.29, -0.71) µg/L) and ADP (0.15(-0.13, 0.36) mg/L), and the medians of differences of after and before dietary intervention in the control group were BMI (0.00(-0.23, 0.29) kg/m(2)), FBG (0.00(-0.03, 0.04) mmol/L), FINS (-0.01(-0.13, 0.04) mU/L), HOMA-IR (-0.01(-0.05, 0.02)), leptin (-0.07 (-0.57, 0.46) µg/L), LCN-2 (-0.85(-5.39, 1.63) µg/L) and ADP (0.02(-0.19, 0.13) mg/L). There were significantly statistical differences between them (Z values were -3.65, -4.88, -3.08, -5.23, -2.16, -4.43 and 3.05, all P values were <0.05).

CONCLUSIONDietary intervention of compound whole grain-soybean can improves glucose level, increase insulin sensitivity and ameliorate insulin resistance state of IFG population.
