Objective To study the value of 5% glucose irrigation for dissection surface hemostasis in laparoscopic conservative treatment of tubal pregnancy. Methods Clinical parameters including numbers of failure in oviduct sparing, the postoperative intraperitoneal bleeding, persistent pregnancy, recurrent tubal pregnancy on the same side and normal uterine pregnancy were compared between the Experimental Group (glucose irrigation for dissection surface hemostasis; 43 cases) and the Control Group (unipolar electrocogulation hemostasis; 43 cases). Results We failed to reserve the oviduct in 10 patients in the Control Group (10/43, 23%) and in no patients in the Experimental Group (0/43) ( ? 2 =11 316, P =0 001). Recurrent tubal pregnancy on the same side was observed in 2 cases in the Control Group (2/34, 6%) and in no cases in the Experimental Group (0/34), without significant differences ( P =0 175). No postoperative intraperitoneal bleeding or persistent pregnancy was seen in both of the groups. Normal uterine pregnancy rates were 44 1% (15/34) in the Experimental Group and 40.0% (10/25) in the Control Group, without significant differences between the two groups ( ? 2 =0 100, P =0 752). Conclusions Use of 5% glucose irrigation is superior to electrocogulation for dissection surface hemostasis in the treatment of tubal pregnancy.

Objective Spermatogonial stem cells(SSCs)dissociated from 2～5 days postpartum mice were cultured on Sertoli cells feeders,to study the effect of Sertoli cells feeders on culture of mouse spermatogonial stem cells.Methods Specific markers CD9 of mouse SSCs cultured serum-free StemPro-34 SFM culture medium were identified by immunohistochemical assay.Result During the first week of culture,on Sertoli cells feeders or STO feeders,the biologica1 behaviors of spermatogonial stem cells showed no obvious difference.After a week of culture,compared with control,there were more number of spermatogonial stem cells remained when they were cultured for 60 days.These cells were expressed CD9 positive.In conclusion Sertoli cells can be used as feeders not only to promote survival but also renewal of spermatogonial stem cells.

OBJECTIVETo observe the effect of total flavones of Epimedium leptorrhizum (YYH-C) on osteoporosis in ovariectomized rats.

METHODOvariectomized female rats were randomly divided into the model group, YYH-C lower, middle and high dose (0.7, 1.4, 2.8 g x kg(-1)) groups, the positive drug Bujiale (0.15 mg x kg(-1)) group, and the sham group. The rats were orally ad-ministrated with drugs for three months. Parathyroid hormone (PTH), procollagen I N-terminal peptide (PINP), alkaline phosphatase (ALP), calcium (Ca) and phosphrous (P) in serum were detected. Femur bones and vertebrae bones of left side were collected to determined bone metrological indexes, including bone mineral density (BMD), bone Ca, and bone ash weight/dry weight percentage. Femur bones of right side were collected to for a morphological observation of bone.

RESULTCompared with the sham group, the model group showed significantly higher PTH and ALP content but obviously lower PINP and Ca content. The three YYH-C 3 groups could resist the decrease of PINP. Specifically, low and middle dose groups could remarkably inhibit the increase of PTH, and the high dose group could increase the Ca content in serum, but without significant effect on the rise in ALP. There was no significant difference in P content in serum in each group. BMD, ash weight/dry weight percentage, Ca and P content of the model group were significantly lower than those in the sham group. The high dose YYH-C group could significantly increase BMD. All of the three YYH-C groups could notably increase ash weight/dry weight percentage and Ca, P content in femur bones and vertebrae bones. YYH-C could significantly increase average thickness, area, area percentage of bony trabeculae, cortical bone area percentage of femoral shaft and the number of osteoblasts on the surface of bony trabeculae, and decrease the number of osteoclasts.

CONCLUSIONYYH-C can effectively control the bone mass loss of rats with ovariectomy-induced osteoporosis, prevent the changes in bone microstructure, and inhibit bone absorption, so as to resist high turn-over osteoporosis after ovariectomy.

Objective To investigate the mRNA expression of survivin, livin and XIAP gene in peripheral blood of patients with gastric cancer and its relationship with clinico-pathological features.Methods This study included 50 patients with gastric cancer and 20 healthy donors. The expression of survivin, livin and XIAP gene was detected by reverse transcription-quantitative polymerase chain reaction (RT-QPCR) using a molecular beacon probe, while recombination plasmid containing the sequence of survivin, livin and XIAP was standard. The relationship between copies of survivin, livin and XIAP gene expression in peripheral blood with gastric cancer and clinical data was analyzed. Results A linear standard curve was obtained between 103 ～ 1010 copies. The copies of survivin, livin and XIAP mRNA in peripheral blood of patients with gastric cancer did not correlate with gender, age, and histological types ( P ＞ 0.05). There were positive relationships between copies of survivin, livin and XIAP gene with lymph node metastasis and TNM stage (P ＜0.05 ). The expression of survivine, livin and XIAP was all negative in peripheral blood of healthy people. 52% (17/33) of patients suffered from recurrence or metastasis who had positive expression of survivin and/or livin and/or XIAP mRNA, while it was 18% (3/17)among the negative survivin and/or livin and/or XIAP mRNA caces ( P ＜ 0.05). Conclusions The expression of survivin, livin and XIAP mRNA can be used to detecte micro-metastasis in peripheral blood circulation of gastric cancer.

Osteoclasts are derived from pluripotent stem cells in bone marrow and spleen.They play a critical role in inflammation-induced bone loss and joint destruction because in the absence of them,bone de- struction does not occur even when inflammation exists.Synovioblasts in an inflamed joint can secrete numerous inflammatory factors,including tumor necrosis factor alpha(TNF-?)and interleukin-1(IL-1)which not only induce inflammatory reactions but also elevate osteoclast formation and function indirectly or directly through promoting RANKL expression.In this wdy the inflammatory reactions are associated with bone loss and destruction. In this article,we focus on the recent progress in study of TNF-?,IL-1 and osteoclast-target therapies in management of osteoclast-mediated inflammatory bone loss.TNF-?promotes differentiation of osteoclast precursor cells in the peripheral blood and spleen,which causes a marked increase in mature osteoclasts in a diseased joint.However, IL-I supports osteoblast survival and regulates the recombination of osteoclast cytoskeleton,which further stimulates bone resorption.Since osteoclast-target therapies may inhibit osteoclast formation and function,they are becoming more and more important for inflammation-induced bone loss and joint destruction.

BACKGROUND:Neurotrophin-3 is found in the repair of spinal cord injury in the role of the strongest neurotrophic factor.It can effectively promote axonal regeneration through the glial scar tissue in repairing spinal cord injury.OBJECTIVE:To construct recombinant lentiviral vectors for gene delivery of homo sapiens neurotrophin-3(hNT3),and to investigate the expression of hNT3 gene in Schwann cells after transfection.DESIGN,TIME AND SETTING:Observational experiment was performed from June 2007 to March 2008 at the Central Laboratory of Changhai Hospital.MATERIALS:Bilateral sciatic nerves were harvested from 3-day-old Sprague Dawley rats for culture and identification of Schwann cells.Three-plasmid lentivirus systems:pGC-E1-EGFP,pHelper 1.0 and pHelper 2.0 were gained from Shanghai Chemical Technology Co.,Ltd.METHODS:pGC-E1-hNT3-EGFP plasmid was constructed by double restriction enzyme digestion and ligation,and then the plasmid was transformed into E.coli DH5?.Purified pGC-E1-hNT3-EGFP plasmids from the positive clones was confirmed by PCR and sequencing.293T cells were cotransfected with lentiviral vector pGC-E1-hNT3-EGFP,pHelper 1.0 and pHelper 2.0 by Lipofectamine 2000 to produce lentivirus.2 mL recombinant virus complete culture solution was added according to multiplicity of infection=1,4,8,10,12.The titer of virus was tested according to the expression level of enhanced green fluorescent protein.The control groups were Schwann cells and Schwann cells transfected by no-loaded lentivirus.MAIN OUTCOME MEASURES:The lentiviruses were transduced to Schwann cells,and the transfection efficiency was examined by flow cytometry,the overexpression of hNT3 was determined by Real-time PCR and Western blotting.RESULTS:The exogenous gene sequence of the recombinant hNT3 was completely in accordance with that of its open reading frame in GeneBank.The titer of concentrated virus was 5?107 TU/L.After recombinant LV-hNT3 infection,Schwann cells gave off strikingly bright green fluorescence,and the transfection efficiency amounted to 85%(multiplicity of infection=10).Real-time RCR test showed that the hNT3 mRNA were highly expressed in hNT3-Schwann cells,while did not express in the control group.Western blotting showed the hNT3 expression in Schwann cells.CONCLUSION:Construction of hNT3 gene lentiviral vector can transfect Schwann cells leading to an efficient overexpression of hNT3.
