Abstract LRR-RLKs plays an important role in multiple signal transduction in plant.One full-length cDNA encoding a LRR-RLKs homologue was isolated from maize through in silico cloning and named as ZmLRRPK1(GenBank accession:EU873320).The predicted ZmLRRPK1 protein has 594 amino acids with an estimated molecular mass of 66kDa and an isoelectric point of 5.42.ZmLRRPK1 has the typical domain of LRR-RLKs.RT-PCR analysis indicated that ZmLRRPK1 expression was induced by ABA,mannitol and salt in coleoptiles of maize and kept high level during 24 hours.

Objective To establish a time resolved fluoroimmunoassay (TRFIA) method for detecting Glypican 3 (GPC3) and to explore the diagnostic value of serum GPC3 for hepatic carcinoma (HCC). Methods Microplate coated with anti-GPC3 monoclonal antibody 7C8 and GP9 labeled with Eu3+ were used to establish TRFIA kit. The serum concentrations of GPC3 in 41 HCC patients and 44 chronic hepatitis (CH) patients were quantitatively analyzed. AFP was detected by with lowest limit of 2.06 μg/L. The CV of inter and intra assay were 12.25% and 12.91%, respectively. The average serum concentration of GPC3 in HCC patients was (86.68±110.39) μg/L (median: 56.98 μg/L). But in CH patients it was only (14.77±29.48) μg/L, which was significantly lower than that in HCC (Wilcoxon W=1335.00, Z=-4.99, P<0.001). With diagnostic cut-off value set at 42.94 μg/L, the diagnostic sensitivity and specificity of TRFIA GPC3 for HCC were 58.5% (24/41) and 95.5%(42/44) respectively. The diagnostic sensitivity of AFP was 46.3% (19/41) in 41 HCC patients, and was raised to 78.0% (32/41) when combined with GPC3. Conclusions Serum GPC3 assay by TRFIA is established and it could increase the diagnostic sensitivity for HCC when combined with AFP.

Aim To investigate the effects of dopamine(DA)on insulin secretion from rat islets and the possible mechanism.Methods Pancreatic islets were obtained from the pancreatic of male SD rats by collagenase P digestion and histopaque-1077 density gradient separation.Insulin secretion experiment was used to observe the change of insulin release after DA treatments.As to study the potential mechanisms of the effects of DA,patch-clamp experiment and calcuim image technique were applied to test the depolarization-evoked Ca2+ currents,action potential duration and intracellular Ca2+ concentration.Results In 2.8 mmol·L-1 glucose,DA had no effect on insulin secretion;in 16.7 mmol·L-1 glucose,dopamine inhibited insulin secretion in a dose-dependent manner.DA inhibited the inward calcium current,shorten the action potential duration,and reduced the intracellular Ca2+ concentration.Conclusion DA inhibits insulin secretion maybe by decreasing the inward calcium current leading to shorten the action potential duration and reduce the intracellular Ca2+ concentration.

OBJECTIVETo evaluate the clinical efficacy and efficacy sustainable time of acupuncture in knee osteoarthritis (KOA).

METHODSThe non-randomized concurrent control trial was adopted. One hundred and ninety-three cases of KOA were divided into an immediate acupuncture group (group A, 97 cases) and a delayed acupunc-weeks at the end of treatment. In group B, the same acupuncture therapy was applied after waiting 4 weeks. The acupoints in the two groups were Liangqiu (ST 34), Dubi (ST 35), Zusanli (ST 36), Yanglingquan (GB 34), Yinlingquan (SP 9), Xuehai (SP 10), Xiyan (EX-LE 4), Xiyangguan (GB 33). WOMAC (Western Ontario and McMasters Universities Osteoarthritis) was used for the assessment of the primary index and VAS (visual analogue scale) was for the secondary index. The evaluation was accomplished by the patients at the beginning of trial, on the 4th and 8th weeks. In each group, 72 patients finished the trial and the data of the lost cases were included in the final data analysis.

RESULTSIn the 4th week of trial, WOMAC score was (25. 8+/-22.0) in group A difference (P<0. 001). VAS scorewas (31. 8+/-24. and was (43.8+/-22.2) in group B, indicating the significant 6) in group A and was (56. 6 +/-25. 8) in group B, indicating very significant difference (P<0. 001). In the 8th week, the efficacy was reduced slightly in the follow-up of group A, but it was improved apparently as compared Acupuncture relieves joint pain and improves joint function obviously.by th patiĩeffr,a Mtaetfti-?an tf ri-with that before treatment.

OBJECTIVETo establish and evaluate a rat model of type 2 diabetes mellitus (T2DM) associated with depression for further elaborating the disease.

METHODSTwenty-four Wistar rats were randomly divided into three groups: normal group (group N), T2DM group (group T) and T2DM with depression group (group T + D), with 8 rats in each group. The T2DM rat model was induced by high fat diet and low dose of Streptozotocin (STZ) injection, and in addition, the T2DM rats were made restraint stress for 21 days. After the model was established, the insulin tolerance test (ITT) and oral glucose tolerance test (OGTT) were performed. Then the rat depression level was analyzed by open field test, and the concentration of 5-hydroxytryptamine (5-HT) and dopamine (DA)was determined by ELISA to confirm the model identity.

RESULTSThe blood glucose level in group T and group T + D didn't return to the normal level at 180 minutes in the ITT and OGTT test; Compared with the group N, the max movement distance, retaining time in the central zone and the retaining frequency within 5 minutes in the group T + D decreased; 5-HT and DA level in the serum of rats in. group T + D was reduced.

CONCLUSIONA rat model of type 2 diabetes mellitus associated with depression has been successfully established by high fat diet and injection of low dose streptozotocin in combination with restraint stress for 21 days. This rat model is useful for further relevant studies.

OBJECTIVE: To establish the 2-dimensional electrophoresis(2-DE) profiles of peripheral blood mononuclear cells(PBMC) in patients with hepatocellular carcinoma(HCC) and health adults. METHODS: The total proteins from PBMC in patients with HCC and healthy adult were separated by immobilized pH gradient-based 2-DE. The differential expression proteins were analyzed by PDQuest analysis software. RESULTS: The well-resolved, reproducible 2-DE patterns of PBMC in patients with HCC and healthy adults were obtained. For HCC, the average spots of 2-DE maps were 1 206 +/- 48, and the average matching rate was 90.8%. For normal adults, the average spots were 1 123 +/- 37, and the average matching rate was 92.6%. CONCLUSION The well-resolved, reproducible 2-DE patterns of PBMC in patients with HCC and healthy adults are established. These proteomic analysis methods are useful to screen the potential biomarkers in the early diagnosis, treatment and prognosis monitor in patients with malignant tumor.
