Objective To translate the English version of the Depression Coping Self-Efficacy Scale (DCSES) into Chinese and test the reliability and validity of the Chinese version of DCSES in patients with depression. Methods Totally 264 patients with depression were recruited and were investigated by the Chinese version of DCSES. Results The total internal consistency coefficient of the Chinese version of DCSES was 0.926, while each dimension were 0.930, 0.908, 0.921, 0.945; split half reliability coefficient was 0.865;the test-retest was 0.752, while each dimension were 0.801, 0.718, 0.729, 0.745, 0.766 (P<0.01);the item-scale correlation ranged from 0.603 to 0.748(P<0.01). Factor analysis got five factors, which explained 58.617% of the total variance. All factor loadings, ranging from 0.447 to 0.762, were statistically significant in the five-factor model and greater than 0.4. Conclusions The Chinese version of DCSES has been proved to be reliable and valid. It can be used as a valid tool for the measurement of the coping self-efficacy in patients with depression.

The etiological factors and pathogenesis of retinopathy of prematurity (ROP) are still unclear,which restricted its effective prevention and treatment.The current animal model widely used in ROP investigation is oxygen-induced retinopathy model,which is lack of specificity,and does not mimic the real pathogenesis status of human ROP patients.Thus,we should refresh our concept,seek breakthroughs in multi-disciplines,integrate more risk factors of ROP,utilize the rising technique in transgenic animal,and improve the evaluation system for improving the current models or explore new animal models of ROP.It is important for prevention and treatment of ROP.

[Objective]To investigate the methods of preparing acellular cartilaginous matrix(ACM) and constructing the tissue engineered cartilage with adipose-derived stem cells(ADSCs)-seeded acellular cartilaginous matrix in vitro.[Method]The ADSCs were isolated from adult New Zealand albino rabbits by collagenase,cultured and amplified in vitro.Fresh cartilage isolated from adult New Zealand albino rabbits were freeze-dried for twelve hours and then treated with Triton X-100,Dnase and RNase so as to obtain the ACM.After sterilized with ultra-violet,the ADSCs were seeded in the acellular cartilaginous matrix at a final density of 2?107/L and cultured in chondrogenic differentiation medium for two weeks in order to construct tissue engineered cartilage.Histology,immunohistochemistry and transmission electron microscope(TEM) were applied to examine the fresh ACM and tissue engineered cartilage.[Result]The test of hematoxylin-eosin(HE) staining and TEM showed no cellular structure in the ACM with only recesses left by removed cells.The ACM had suitable interval porosity and aperture size.After integrated with ADSCs,cells migrated into the ACM and adhered to the surface of material and grew well.After cultured in chondrogenic differentiation medium for two weeks,immunohistochemical staining of type Ⅱ collagen showed part of the cells in the material had enhanced expression of type Ⅱ collagen.[Conclusion]ACM can be used as scaffold material in cartilage tissue engineering.If it was seeded with ADSCs and cultured in chondrogenic differentiation medium,ACM can be used to construct cartilage tissue successfully.

BACKGROUND:Adipose-derived stem cel s and bone marrow mesenchymal stem cel s are used widely in cartilage tissue engineering, and there are many similarities in biological characteristics between two kinds of cel s. OBJECTIVE:To compare the chondrogenic potential of bone marrow mesenchymal stem cel s and adipose-derived stem cel s in vitro. METHODS:Adipose-derived stem cel s were isolated from the 3-month-old New Zealand white rabbits’ abdomen. Bilateral femurs of rabbits were obtained, and then the bone marrow mesenchymal stem cel s were separated with the adherence screening method. The growth curve of the passage 3 adipose-derived stem cel s and bone marrow mesenchymal stem cel s were drawn, and the doubling time of two kinds of cel s was compared. Then the passage 3 adipose-derived stem cel s and bone marrow mesenchymal stem cel s were treated with chondrogenic induction. After induced for 14 days, the adipose-derived stem cel s and bone marrow mesenchymal stem cel s were treated with toluidine blue staining and type Ⅱ immunohistochemistry staining respectively. RESULTS AND CONCLUSION:Primary bone marrow mesenchymal stem cel s showed aggregative growth, while the primary adipose-derived stem cel s were in single and scattered growth. The proliferation speed of adipose-derived stem cel s was faster than that of bone marrow mesenchymal stem cel s, while the doubling time of adipose-derived stem cel s was shorter than that of the bone marrow mesenchymal stem cel s. After chondrogenic induction for 14 days, both adipose-derived stem cel s and bone marrow mesenchymal stem cel s could express glycosaminoglycans and type Ⅱcol agen, and the expression level of type Ⅱ col agen in bone marrow mesenchymal stem cel s after chondrogenic induction was higher than that in the adipose-derived stem cel s. The in vitro proliferation of adipose-derived stem cel s and bone marrow mesenchymal stem cel s was rapid and stable, but the proliferative ability of adipose-derived stem cel s was faster than that of bone marrow mesenchymal stem cel s. When cultured in single layer, both adipose-derived stem cel s and bone marrow mesenchymal stem cel s could transform into chondrocytes under certain conditions, but bone marrow mesenchymal stem cel s seemed to be more potential than adipose-derived stem cel s.

3.Three cases failed to respond to treatment.Two cases had recurrence 7 and 9 months after treatment.The effective rate was 82%. The ICSI score was decreased to 6.1?3.4 at 1 month,6.3?3.5 at 2 months (P

By using of combined HRP retrograde tracing and immunocytoche mistry methods, the projection from the caudal part of the ventrolateral medulla (VLM) to the nucleus accumbens (Acb) was examined. When HRP was injected into the ventral and medial area of the caudal part of Acb, the labeled cell bodies were mostly found in the bilateral (predominantly ipsilateral) caudal part of the VLM. When HRP technique (HRP injected into the Acb)was combined with immunocytochemical method, many HRP-TH, HRP-NT and HRP-CCK double labeled cell bodies were found in the VLM. The number of the HRP-TH double labeled cell bodies were numerous, while HRP-NT and HRP-CCK doublelabeled cells were less. HRP-TH double labeled neurons were also found in the reticular formation between the solitary tract nucleus and VLM.

24 cases of hypoparathyroidism, 24 cases of normal control were included. The levels of enzymes, concentration of Ca were measured in all cases. The electrocardiogram was carried out in the hypoparathyroidism group carries. The levels of CK, CK-MB, BHDH, LDH and AST were significantly higher in patients with hypoparathyroidism than in normal control cases(P＜0.05), especially the levels of CK and CK-MB (P＜0.01). After the treatment, the electrocardiogram and enzymes basically returned to normal. The changes of enzymes in patients with hypoparathyroidism may play a benchmark about the severity and treatment.

BACKGROUND: Now, dual-energy X-ray absorptiometry is international y recognized as gold standard for the diagnosis of osteoporosis, but the errors can be found in the measurement results due to the heterotopic ossification and bone hyperplasia exists in the measurement part. OBJECTIVE: To investigate the clinical significance of bone metabolic markers in the diagnosis and treatment of elderly patients with osteoporotic fractures, and to research its correlation with the changes of pathological histology and bone mineral density. METHODS: Four bone biochemical markers in 50 elderly patients with osteoporosic fractures were measured preoperatively. According to the results, 25 patients had significantly increased tartrate-resistant acid phosphatase 5b (considered as the increased tartrate-resistant acid phosphatase 5b group), and 25 patients had increased bone alkaline phosphatase (considered as the increased bone alkaline phosphatase group). During operation, the bone tissues of eight patients in each group were treated with hematoxylin-eosin staining and electron microscopy scanning in order to detect the pathological changes. After operation, the patients in the increased tartrate-resistant acid phosphatase 5b group received salmon calcitonin anti-osteoporosis treatment, and the patients in the increased bone alkaline phosphatase group received the anti-osteoporosis treatment of bone peptide injection. The bone mineral density and the four bone biochemical markers were detected again at 6 months after treatment. RESULTS AND CONCLUSION: There were no significant differences in the preoperative bone mineral density and four biomechanical markers between two groups (P > 0.05). The pathological examination results of bone tissue on the fracture site showed that the number of osteoblasts was reduced and the number of oeteoclasts was increased in the increased tartrate-resistant acid phosphatase 5b group; while in the increased bone alkaline phosphatase group, the pathological examination results showed the number of osteoblasts was reduced; the trabecular bone/bone area ratio was decreased in two groups, and there was a significant difference in the decrease degree between two groups (P < 0.05). The electron microscope scanning showed that the osteoclasts of two groups were more active than that of the normal group. The sloppy of trabecular bone in the increased tartrate-resistant acid phosphatase 5b group was more obvious than that in the increased bone alkaline phosphatase group, and the absorption vacuoles were increased. There were significant differences in the bone mineral density and four biomechanical markers between two groups before and after anti-osteoporosis treatment (P < 0.05). The detection of bone metabolic markers could help us to make it clearly that the main function of osteoblast reduce or osteoclast increase in bone tissue of patients, and guide us to use anti-osteoporosis drugs in target. Pathological histology examination can better reflect the condition of osteoblasts, osteoclasts and trabecular bone in bone tissue on the fracture site. Target application of anti-osteoporosis drugs in the osteoporosis patients can effectively improve the efficacy and reduce the relative complications.

Objective To investigate the effects of the two major conjugated linoleic acid(CLA) isomers on serum lipoprotein composition in fatty rats.Method Eighteen male OLETF rats were randomly divided into three groups.The control group fed with AIN76 diets,CLA groups were fed with 1% 9c,11t-CLA (9ct group) or 1%10t,12c-CLA (10tc group) containted AIN76 diets.After two weeks,serum triglyceride (TG),total cholesterol (TC),and high density lipoprotein cholesterol (HDL-c) were determined by commercial kits.On the other hand,serum lipoprotein were separated into chylomicron(CM),very low density lipoprotein(VLDL),low density lipoprotein(LDL) and HDL by HPLC according to the different particle sizes,and the TC and TG levels were measured in each lipoprotein.Results 10t,12c-CLA feeding reduced the concentrations of rat serum TG significantly,and increased the concentration of serum TC (26.1%) by increasing TC levels of the small particle size LDL and the big particle size HDL.While 9c,11t-CLA feeding increased the serum TG by 22.6%,and had no effect on the serum TC.Conclusion 10t,12c-CLA can reduce the concentration of serum TG and increase the concentration of HDL-c,but the effect on the improvement of atherosclerosis still need further investigation.

Objective: To study the antioxidative and hepatoprotective activities of low molecular fucoidan oligosaccharides(LMFO) from Laminaria japonica in mice.Methods: Mice were pretreated with LMFO(50?100?150 mg/kg ig respectively, 10 days),and then 0.2 % CCl 4 10 ml/kg ig and D-GalN(600 mg/kg)+LPS(lipopolysaccharide,1 ?g/kg) ig respectively in two model groups to induce liver injury. Liver injury was assessed by quantifying activities of plasma GPT, SOD, GSH-Px and MDA content.Results: The increase of plasma GPT activity was significantly inhibited by LMFO in two liver injury models, suggesting that LMFO had good protective effect on the hepatocytes. LMFO had good antioxidative effect in mice with liver injury induced by CCl 4 and D-GalN+LPS as indicated by decreased MDA content and increased activities of plasma SOD and GSH-Px. Conclusion: LMFO is protective against CCl 4-induced and D-GalN+ LPS induced liver injury in mice and its effect may be due to its antioxidative activities in vivo.
