Objective To explore framework and measure of vocational psychological quality for postgraduate students majoring in med-ical sciences in China. Methods The framework of vocational psychological quality had been developed based on the grounded theory. A structured and standardized questionnaire had been developed via field test for 95 postgraduates and interviews with 24 experts. A total of 1142 postgraduates had been measured with the final questionnaire. Results The standardized questionnaire had been developed including 3 subscales from factor analysis, such as vocational cognition, vocational personality and vocational adaptation, with 13 factors and 62 items in total. The Cronbach'sαcoefficient was 0.902 for the whole questionnaire, and the split-half reliability was 0.747. The correlation coeffi-cients between subscales and whole questionnaire was 0.401 to 0.929. Conclusion Vocational cognition, vocational personality and vocation-al adaptation are the main constituents of the vocational psychological quality for postgraduates majoring in medical sciences. The question-naire is acceptable in content and structure validity and internal consistency reliability.

Two-dimensional electrophoresis performed on a microfluidic chip could reduce the consumption of sample and reagents, realizing high-throughput analysis in a very short time. During the isoelectric focusing ( IEF) separation, the buffer for the two different separation methods should be kept from being mixed. After the IEF, the protein was transferred from the IEF channel into the second dimension channels. Based on the pseudo valve structure, this paper reported a method to deposit a titanium dioxide membrane at the interface of two dimensional channels, which enhanced the performance of the pseudo valve. The IEF electrophoresis and SDS-polyacrylamide gel electrophoresis ( SDS-PAGE ) procedures were characterized respectively. The total separation took 10-15 min, and the protein's migration rate was linear with the migration time, and inversely proportional to the logarithm of protein molecular weight. Based on the above results, the differential two-dimensional electrophoresis was performed to test the deviation between different measurements.

Objective: To observe the inhibitory effect of Fuzheng Xiaoliu Decoction (FXD) on cerebral glioma. Methods: Rat glioma orthotopic transplantation model was established by inoculating C6 glioma cells to brain right caudate nucleus in situ of Wistar rats, and the rats in treatment group were ig administered with FXD for consecutive 14 d. After the last administration, blood was taken to measure whole blood viscosity and plasma viscosity, serum immunoglobulin (IgG, IgA, and IgM), tumor necrosis factor-α (TNF-α), interleukin-2 (IL-2), and interferon-γ (IFN-γ) levels; All rats were sacrificed after last administration to collect whole blood; The brain was taken and weighed, brain index was calculated, tumor length and short diameters were measured, and tumor volume and inhibitory rate were calculated; The tumor tissue was taken, vascular endothelial growth factor (VEGF) and prostaglandin E2 (PGE2), insulin-like growth factor-1 (IGF-1) levels were determined. Results: All three doses (1.2, 2.4, and 3.6 g/kg) of FXD could inhibit rat glioma tumor volume. It could reduce the contents of IGF-1, PGE2, VEGF in tumor tissue and serum IgG, elevated the level of serum IgA, IgM, TNF-α, IL-2, and IFN-γ to varying degrees. FXD (3.6 g/kg) can reduce whole blood viscosity at low shear (P < 0.05, 0.01). Conclusion: FXD has significant antitumor effect on C6 glioma, and the mechanism of antitumor effect may be the inhibition of tumor angiogenesis and tumor cell proliferation, enhancing immune response, and reducing blood viscosity.

Objective: To observe the effects of Jimaitong Tablet on the blood pressure, liver and kidney function, and vasoactive substances of the rats with long-term drinking. Methods: Forty SD rats were divided into four groups including control, model, Jimaitong Tablet, and Amlodipine groups (n = 10). The rats drinking spirits freely, and the alcohol concentration increased in gradient. After 4 weeks of modeling, the rats were ig administered successively for 49 weeks, once daily. The blood pressure (such as SBP, DBP, and MBP) and blood biochemical markers of liver and kidney function (such as ALT, AST, Cr, and UA) had been regularly monitored. After the last administration, the rat blood was collected from the inferior vena cava plexus, and the angiotensin II (AngII), aldosterone (ALD), and thromboxane B2 (TXB2) levels in plasma were measured. Results: The blood pressure (SBP, DBP, and MBP) of rats increased after 12-week continuous drinking and was stable until week 53. After the administration of Jimaitong Tablet for 15 weeks onwards, the blood pressure (SBP, DBP and MBP) of rats with long-term drinking could be significantly reduced. It showed stable antihypertensive effect during the administration for up to 49 weeks (P < 0.01, 0.05). Jimaitong Tablet could improve ALT and AST levels in serum to varying degrees (P < 0.01, 0.05) at the administration of 38-48 weeks. Jimaitong Tablet could reduce ALD, AngII, and TXB2 levels (P < 0.01, 0.05) in plasma of the model rats during the administration of 49 weeks. Conclusion: Jimaitong Tablet has good effect on hypertensive rats induced by long-term drinking, and has a distinct improving effect on liver injury in rats. Its mechanism of the antihypertensive effect may be related to the renin-angiotensin-aldosterone system and thromboxane level.

Objective To investigate the mechanism underlying the protective effect of hyperbaric oxygen (HBO) in secondary spinal cord injury (SCI). Methods Models of acute SCI were established in 96 SpragueDawley rats using Allen's dropping weight technique. The rats were then divided into a HBO group, a high pressure nitrogen normal oxygen group, a normal pressure oxygen group and a normal pressure air group. The injured spinal cords were sampled for morphological studies at the 1 st, 3rd, 7th and 14th day after injury. Apoptotic cells were labeled using the TUNEL technique, and the expression of caspase-3 was detected. The neurological functionality of the spinal cord was assessed by open field locomotor evaluation ( the BBB score). Results The expression of caspase3 in the HBO group decreased significantly more than in the other groups after injury. The number of TUNEL-positive cells was significantly lower in the HBO group as well. Neurological function improved significantly after HBO therapy. Conclusions HBO can down-regulate the expression of caspase-3 and inhibit cell apoptosis in rats after SCI.The protective effect of HBO was related with the oxygen level.
