Objective To study the effects of bone marrow mesenchymal stem cells (BMSCs) transplantation on the ischemia-reperfusion injury of the intestine in rats.Methods BMSCs were isolated from femur of male Wistar rats and cultured,and the phenotypes of third generation cultured cells were identified.B16-F10-Luc-G5 cells were injected into the intestinal submucosa and traced by Luciferin.Intestinal ischemia-reperfusion injury models were established in male Wistar rats,which were divided into the experimental group (1 ml BMSCs suspension which contained 5 × 106 cells was injected into the intestinal submucosa) and the control group (1 ml normal saline was inject into the intestinal submucosa).Then,serum and intestinal tissue samples were collected at 0,2,6,24,72 and 120 h after operation.Diamine oxidase,D-lactate and TNF-α were tested by ELISA,intestinal tissue samples were observed under the Light microscopy and transmission electron microscopy,and tight junction protein-1 (ZO-1) was detected by using Western blotting and immunohistochemistry.Results BMSCs were isolated and cultured successfully and they colonized in the intestine.The pathological changes of the intestine in experimental group were milder than in control group. Intestinal mucosal barrier was more intact in experimental group than in control group.In the experimental group and control group,DAO was (11.36 ± 1.89) and (14.27 ± 2.09)IU/ml (P＜0.05) at 6th h after injection,and that was (5.04 ± 1.04) and (7.35 ± 1.46) IU/ml (P＜0.05) at 24h after injection,respectively.In the experimental group and control group,D-lactate was (1.57 ± 0.25) and ( 1.93 ± 0.19) mmol/L (P＜0.05) at 6th h after injection,and that was ( 1.09 ± 0.13) and ( 1.41 ± 0.07) mmol/L (P＜0.01 ) at 24th h after injection,respectively.In the experimental group and control group,TNF-α was (266.09 ± 8.84) and (286.81 ± 11.54) ng/L (P＜0.01 ) at 6th h after injection,and that was (190.39 ± 4.24) and (218.49 ± 15.51 )ng/L (P＜0.01 ) at 24th h after injection,respectively.The expression of ZO-1 protein was higher in experimental group than in control group. ConclusionInjection of BMSCs into could protect the intestine from ischemia-reperfusion injury in rats.

Totally 177 individuals (87 males and 90 females), who took abdominal computer tomography were enrolled. Anthropometric surrogates such as abdominal height( AH), waist circumference( WC), body mass index(BMI), and waist to height ratio(WHtR) were measured. Correlations between AH, WC, BMI, and WHtR with visceral abdominal fat were analyzed, and receiver operating characteristic curves ( ROC) were prepared for detecting abdominal adiposity at or beyond 80cm2 using lumbar vertebra 4-5 cross-section visceral fat areas as the screening cut-point within gender separately. Youden′s index was used to determine cut-off values of AH, WC, BMI, and WHtR by which to classify excess abdominal fat. 70(80. 5% ) males and 59(65. 9% ) females had abdominal obesity. Compared to other anthropometic indicators, AH presented the highest correlation with visceral adipose fat. The pearson correlation efficiencies were 0. 825 and 0. 732, the cut-off points were 20 cm and 20. 3 cm in male and female respectively. After controlling for age, receiver operating characteristic analysis showed that AH, followed by WHtR, outperformed WC and BMI in identifying central obesity participants. Optimal cut-off values of the physical anthropometric indices to indentify abdominal adiposity were 20 cm(AH), and 91 cm(WC) 25 kg/ m2 (BMI), and 0. 52(WHtR) for men, and 20. 3 cm(AH), 86. 5 cm(WC), 25 kg/ m2(BMI), and 0. 54(WHtR) for women. AH is effective for predicting visceral adiposity and might be considered the best predictor of abdominal obesity at a cut-point of 20cm in Chinese adults.

OBJECTIVETo establish a method for the determination of gypsum and magnesium in decoction by capillary zone electrophoresis and study the influence of different compatibility on the contents of calcium and magnesium dissolution.

METHODNine decoctions with gypsum were prepared and analysed by L9 (3(4)) orthogonal design and the contents of calcium and magnesium ions were determined by the set method. The conditions of the experiment were a running buffer of 6.4 mmol x L(-1) imidazole solution (glacial acetic acid ajusted pH to 3.50) and an applied voltage of 10 kV (room temperature). Samples were introduced by hydrodynamic injection (8 cm x 7 s) and determined with on-column UV monitoring at 214 nm. Copper sulphate was chosen as the internal standard.

RESULTSThe linear responses covered the range from 0.009 68 mg x L(-1) to 9.68 mg x L(-1) (r = 0.998 1) for calcium, the detection limits (S/N = 3) and the quantitation limits (S/N = 10) of calcium were shown to be 0.002 1 mg x L(-1) and 0.007 1 mg x L(-1), respectively. The average recovery for calcium was 100.4%. The linear response covered the range from 0.01 mg x L(-1) to 10 mg x L(-1) (r = 0.995 9) for magnesium. The detection limits (S/N = 3) and the quantitation limits (S/N = 10) of magnesium showed to be 0.002 8 mg x L(-1) and 0.008 9 mg x L(-1), respectively. The average recovery for magnesium was 96.4%.

CONCLUSIONThe method is simple, rapid, cost-effective and precise with satisfactory results. The influence of Ephedra and Semen Armeniacae Amarum on the contents of gypsum dissolution are significant, while that of Radix Glycyrrhizae on the contents of gypsum dissolution is insignificant. The influence of Ephedra on the contents of magnesium dissolution are significant, while that of Semen Armeniacae Amarum and Radix Glycyrrhizae on the contents of magnesium dissolution are insignificant.

Conclusion Less children with cerebral palsy had registered, and received insufficient rehabilitation.

Present study aimed to investigate the eff ect of curcumin-pretreatment on intestinal I/R injury and on intestinal mucosa barrier. Thirty Wistar rats were randomly divided into: sham, I/R, and curcumin groups (n=10). Animals in curcumin group were pretreated with curcumin by gastric gavage (200 mg/kg) for 2 days before I/R. Small intestine tissues were prepared for Haematoxylin & Eosin (H&E) staining. Serum diamine oxidase (DAO) and tumor necrosis factor (TNF)-alpha levels were measured. Expression of intestinal TNF-alpha and tight junction protein (ZO-1) proteins was detected by Western blot and/or immunohistochemistry. Serum DAO level and serum and intestinal TNF-alpha leves were signifi cantly increased after I/R, and the values were markedly reduced by curcumin pretreatment although still higher than that of sham group (p<0.05 or p<0.001). H&E staining showed the significant injury to intestinal mucosa following I/R, and curcumin pretreatment signifi cantly improved the histological structure of intestinal mucosa. I/R insult also induced significantly down-regulated expression of ZO-1, and the eff ect was dramatically attenuated by curcumin-pretreatment. Curcumin may protect the intestine from I/R injury through restoration of the epithelial structure, promotion of the recovery of intestinal permeability, as well as enhancement of ZO-1 protein expression, and this eff ect may be partly attributed to the TNF-alpha related pathway.

IFN-gamma and TNF-alpha were co-coupled to the polystyrene cell culture plate by the photo-immobilization method. To investigate the synergistic effect of IFN-gamma and TNF-alpha on the HeLa cells, HeLa cells were treated with co-coupled cytokine or non-coupled cytokine in a time course in this study. The morphology detection, cell cycle analysis by flow cytometry, phosphatidyl serine analysis and capase-3 activity detection demonstrated that the two kinds of treatments both induce HeLa cells apoptosis. Non-coupled cytokine worked more quickly while co-coupled cytokine kept more permanent effect. The caspase-3 activity assay indicated that the caspase-3 activity of HeLa cells treated with non-coupled cytokine is higher than that of HeLa cells treated with co-coupled cytokine. This may imply that co-coupled cytokine not only induces the caspase-dependent pathway, but also induces the caspase-independent pathway.

Apelin is an adipokine family which includes Apelin-13,Apelin-36 and other isoforms and regulates phys-iological functions by immunomodulation,oxidative stress,glycolipid metabolism,and apoptosis and so on.Apelin is closely related to polycystic ovary syndrome,ovarian cancer and other diseases of the female reproductive system so it is expected to be new target molecules and may orient the development of research and clinical treatment.
