Objective To explore the construct validity of the Chinese version of Kinesthetic and Visual Imagery Questionnaire (KVIQ)-20 and KVIQ-10 in stroke patients and normal people. Methods From October, 2012, to March, 2014, 60 stroke patients and 60 nor-mal people with matched gender and age participated in this study. They were assessed with the Chinese version of KVIQ-20 and KVIQ-10. The construct validity was investigated with factor analysis. Results Two factors were extracted from KVIQ-20 for stroke patients after vari-max rotation, that accounted for 62.4%of the variance, as well as KVIQ-10 with 67.6%of the variance. Two factors were extracted from KVIQ-20 for normal people with 76.1%of the variance, as well as the KVIQ-10 with 69.6%of the variance. The factors could be named as visual imagery and kinesthetic imagery. Conclusion The Chinese version of KVIQ-20 and KVIQ-10 has good construct validity for assess-ing motor imagery from the dimensions of visual imagery and kinesthetic imagery, both in patients with stroke and normal people.

Objective To evaluate the effects of pregnancy weight control program based on structure- process- outcome model to improve women′s health status and pregnancy outcomes. Methods On the basis of Donabedian′s structure- process- outcome quality of care model, a pregnancy weight control program designed and carried out for the middle and late pregnancy. The structure, process and outcome of the pregnancy weight control program were evaluated to ensure the quality of the pregnancy weight control program. In addition, the women′s pregnancy outcomes were investigated after intervention. Results the prenatal BMI in the intervention group [ (23.06±1.11) kg/m2 ] were lower than those in the control group [(25.52±1.89) kg/m2 ], and the incidence of cesarean section (including cesarean section without indication), neonatal macrosomia, labor block, neonatal asphyxia, postpartum hemorrhage, pregnancy induced diabetes and hypertension in the intervention group were significantly lower than those in the control group, P<0.01 or 0.05. Conclusion Donabedian′s structure- process- outcome quality of care program is an effective approach to improve women′s pregnancy outcomes.

Objective To synthesize glycylproline p-nitroanilide tosylate as a substrate for glycylprolyl dipeptidyl-aminopeptidase(GPDA),and to study its clinical application.Methods The title compound was prepared by DCC-HOBt synthesis.GPDA in human serum was detected by continuous monitoring method using substrate. Results The substrate with purity of 98.5% was obtained.The linearity of the method was up to 358.1 U/L.Intraassay CV and interassay CV of GPDA in diverse serum samples were 3.01% and 5.04%,respectively.It was shown that GPDA level in patients with hepatic cancer was significantly increased,while those in patients with gastric carcinoma and chronic gastritis were significantly decreased compared with that in the control group in clinical detecting(P

BACKGROUND: The source of bone marrow mesenchymal stem cells (BMSCs) is limited, and the cellular morphology,proliferation and multi-directional differentiation capacities can vary during serial passages in BMSCs in vitro.OBJECTIVE: To study the effects of fibroblast growth factor (FGF) on cellular morphology, proliferation and differentiation of serially passaged BMSCs.METHODS: (1) BMSCs were isolated from Sprague-Dawley rats and cultured. These cells were passaged six times in vitro, and the cellular morphology was observed and photographed. (2) BMSCs at passage 6 were seeded into 96-well plates and randomly divided into control group and FGF treatment group. The proliferation of cells in both groups was detected with cell counting kit-8 kit at days 1, 2, 3, 4, 5, 6, 7 after culture. (3) BMSCs at passage 6 were seeded into 6-well plates and randomly divided into control group and FGF treatment group. After 7 days treatment with growth medium or growth medium containing FGF, the cellular morphology was observed and photographed. And then the cells of both groups were treated with osteogenic induction medium, adipogenic induction medium and chondrogenic induction medium for the next 7 days. The osteogenic, adipogenic and chondrogenic related genes (RUNX2, ALP, OCN;PPARγ2, AP2, ADIPOQ; SOX9, collagen II, aggrecan) were detected with real-time PCR. The protein expressions of RUNX2, PPARγ2, SOX9 were detected with western blot assay. (4) BMSCs at passage 6 were seeded into 6-well plates and randomly divided into control group and FGF treatment group. After 7 days treatment with growth medium or growth medium containing FGF, the cells were cultured with osteogenic induction medium, adipogenic induction medium and chondrogenic induction medium for the next 14 days. Then, alizarin red S staining, oil red O staining and alcian blue staining were performed.RESULTS AND CONCLUSION: (1) After in vitro passage for six times, the cellular morphology changed obviously, and FGF treatment recovered the characteristics of primary cells. (2) Compared with the control group, the cell proliferation in the FGF treatment group was significantly increased (P < 0.05). (3) Compared with the control group, the expression of osteogenic, adipogenic and chondrogenic related genes (RUNX2, ALP, OCN; PPARγ2, AP2, ADIPOQ; SOX9, collagen II, aggrecan) was increased significantly in the FGF treatment group (P < 0.05). The protein expressions of RUNX2,PPARγ2, SOX9 were also higher in the FGF treatment group than the control group (P < 0.05). (4) Compared with the control group, the number of extracellular calcium nodules, the number of intracellular lipid droplets, and the expression of acid acidic mucopolysaccharide were significantly increased after FGF pretreatment. To conclude, FGF pretreatment can preserve the stemness of BMSCs serially passaged in vitro.

ObjectiveTo explore the influence of electrical stimulation on nervous cells.MethodsOn 5th day the brain primitive nervous cells of rat brain, in vitro culturing, were divided into 4 groups, in order of control group, electrical pole control group, low stimulation group, and high stimulation group. The cells were stimulated with electro-acupuncture apparatus for 7 days, 30 minutes once, twice a day. On 10th day, the cells were observed microscopically for 3 days and taken photos.ResultsElectrical stimulation is helpful to raise the survival rate of cell.Conclusions Electrical stimulation influences morphological change of nervous cells during culturing.

ObjectiveTo study the effects of aqueous extract of Trigonella foenum-graecum(AET) on the blood glucose in normal and alloxan(ALX)-diabetic mice.MethodsFasting blood glucose and glucose tolerance in normal and ALX-diabetic mice were measured respectively 7 days after AET had been given.ResultsAET had not significantly effected the fasting blood glucose of normal mice, but improved their glucose toleranc. Otherwise, AET reduced fasting blood glouse of diabetic mice induced by ALX significantly.ConclusionAET can be used on treatment of diabetes mellitus.

OBJECTIVETo investigate the effect of intralipid on protein consumption in severe burned patients. METHODS; Sixty-seven nonoperative patients with severe burns were divided into Intralipid treatment group and non-intralipid treatment group (control group), and the former was treated with 20% intralipid (500 ml once a day) from postburn day 4 for 10 consecutive days. Venous blood samples were collected from these patients for testing total protein, albumin, total cholesterol and triglyceride on postburn days 1, 7 and 14, respectively.

RESULTSThe levels of total protein, albumin, total cholesterol and triglyceride were within normal range on postburn day 1 in both groups, and only the albumin level was lowered in the groups on day 7 but at comparable magnitudes (32+/-4.83 vs 31+/-5.04 g/L, P<0.05). In contrast, the levels of total protein, albumin, total cholesterol and triglyceride were below the normal range on postburn day 14 in both groups, but intralipid treatment group showed more albumin loss than the control group (28+/-6.46 vs 23+/-7.03 g/L, P<0.01).

CONCLUSIONIntralipid (20%) provides good energy source to ameliorate albumin loss in severe burned patients.
