BackgroundHuman retinal gliocytes play an important role in proliferative diseases,which are the basis of in vitro studies.Researchers have cultured human retinal gliocytes in the past.In our study,we found that the cells we cultured presented a unique shape different from those by other researchers.ObjectiveThis study was to design to produce a new culture and purification method for retinal gliocyte in vitro.Methods Retinal tissue was isolated from human eyeballs and digested using the two-step digestion method (2％ pancreatin and 0.133％collagenase Ⅵ) to harvest the retinal glio cytes.The cells were collected and cultured in endothelial cell-targeted nutrient culture containing 10％ fetal calf serum and supplemented with β-endothelial cell growth factor (ECGF) and sodium heparin,and the culture dishes were coated with fibronectin(FN) to promote the attachment of retinal gliocyte.During the culturing process,the gliocytes were identified by the observation of morphological characteristic and regular histological examination.The identification of the cells also was performed by immunochemistry targeting glial fibrillary acidic protein (GFAP),Vimentin,neuron specific enolase ( NSE ),S-100,CD34,and Ⅷ factor.Results Retinal gliocytes were isolated successfully from the human retina by the two-step digestion method.Primary cultured cells attached after 72 hours and achieved confluency between day 9 and 10 that were aligned petaliform in shape.Regular histological examination after H&E staining showed blue cell nuclei and light red cytoplasm.The target cells presented with strong responses for GFAP and Vimentin and no response for NSE,S-100,CD34 and Ⅷ factor.ConclusionsLarge amount of purified human retinal gliocytes can be obtained by two-step digestion and cultured in endothelial cells-targeted culture medium supplemented with β-ECGF and sodium heparin in plates coated with FN.The cultured cells expressed markers for retinal gliocytes.However,specific features of these cells remain to be further elucidated.

A new neo/E counterselection technique was set up using Red recombination, which could be used in constructing recombinant plasmid. Firstly, linear targeting cassettes were amplified by PCR; secondly, two steps of homology recombination occurred in vivo: (1) The neo/E counterselection targeting cassette, consisting of a unique endonuclease recognition site and an antibiotic resistance gene, was introduced into the targeted region. (2) The neo/E cassette was replaced in the second round of recombination by another linear targeting cassettes DNA fragment carrying the targeted gene. For selecting a correct recombinant plasmid from the mixture of nonrecombinant and recombinant clones, the unique endonuclease recognition site in the nonrecombinant clones was cut by endonuclease and then transformed into the E. coli competent cells, up to 20% correct recombinants were yielded. A recombinant plasmid of pGL3-Basic PC1900T was successfully constructed in this way. Application of this technique offers a new and highly efficient way for recombinant plasmids construction.

Objective To evaluate the clinical nursing pathway in the treatment of stroke patients in combination with traditional Chinese medicine and western medicine. Methods A hundred patients were randomly divided into observation group and control group, 50 cases of each, which selected in Zhoushan Hospital of Traditional Chinese Medicine from January to December in 2015. The normal nursing methods were used in the control group and the clinical nursing paths were used in the observation group. Results The average value of Barthel score of the observation group was significantly better than that of the control group (55.93±9.12 vs. 46.51±9.29, P<0.05) . The recovery efficiency of the observation group was significantly higher than that of the control group (90.00％ vs. 62.00％, P<0.05) . The score of satisfaction of nursing work in the observation group was higher than that of the control group (9.13±0.49 vs.7.08±0.72, P<0.05), and the average length of stay was shortened (43.62±3.79 vs. 65.13±3.11, P<0.05) respectively compared with the control group, and the curative effect of topsis was evaluated by topsis method, and the Ci value of the observation group (Ci=0.781) was better than that of the control group (Ci =0.219) . Conclusion The clinical nursing pathway could significantly improve stroke patients Barthel score, muscle strength and nursing job satisfaction, and overall reduce the duration of hospital stays.

OBJECTIVETo observe the therapeutic efficacy of dietary boron supplement on retinoic acid-induced osteoporosis in rats, so as to provide experimental evidence for clinical management of osteoporosis with boron.

METHODSThirty-two SD rats were randomized into normal control group (8 rats) and osteoporotic group (24 rats), and osteoporosis was induced in rats of the latter group by intragastric retinoic acid administration at the daily dose of 80 mg/kg for 15 consecutive days. The osteoporotic rats were subdivided into control group (8 rats) without treatment, boron treatment group (8 rats) and estradiol treatment group (8 rats). After 30 days of treatment, the serum contents of Ca, P, boron and the activities of alkaline phosphatase (AKP) and tartrate-resistant acid phosphatase (TRAP) in the rats were assayed, the bone mineral density (BMD) of the whole body, lumbar vertebrae and tibia were determined, and the morphological changes of the femurs were observed.

RESULTSThe serum contents of Ca and P in the rats of the 4 groups differed scarcely, but the content of boron in boron treatment group was markedly higher than that in the other three groups. In the osteoporotic control group, the activities of serum AKP and TRAP, the masses of spongy bone and cortical bone of the femurs, and the quantity of the osteoclasts were increased, with the BMD of the lumbar vertebrae and tibia decreased, suggesting osteoporotic conditions. The mean trabecular plate density and thickness, trabecular bone volume and cortical bone volume of the femurs in the osteoporotic rats treated with boron or estradiol were significantly increased, but the active osteoclast quantity in the spongy bone and serum TRAP activities were obviously decreased, and the bone quality was comparable with that of the normal group. In addition, the serum AKP activity and the active osteoblast quantity in the spongy bone were obviously increased in boron treatment group.

CONCLUSIONThe dietary boron supplement can increase the serum content of boron of osteoporotic rats to stimulate bone formation and inhibit bone resorption, producing therefore obvious therapeutical effect against osteoporosis.

OBJECTIVETo evaluate the value of high mobility group box 1(HMGB1) in the diagnosis of pediatric acute appendicitis.

METHODSThe children with acute abdomen who had a diagnosis of suspected acute appendicitis between January and July 2013 and 25 healthy children were enrolled in this study. Serum HMGB1 levels were measured using ELISA on admission. The patients were classified into 2 groups according to surgery confirmation or pathological results: appendicitis (n=28) and non-appendicitis (n=35).

RESULTSSerum HMGB1 levels and WBC in the appendicitis and non-appendicitis groups were significantly higher than in the healthy children group (P<0.01). The appendicitis group showed more increased serum HMGB1 levels compared with the non-appendicitis group (median: 32.9 ng/mL vs 22.0 ng/mL; P<0.01). For a diagnosis of acute appendicitis, the sensitivity and specificity of serum HMGB1 was 71.4% and 82.9% respectively at the best cutoff of 28.0 ng/mL, with the accuracy of 77.8% and the area under the curve of 0.765 (95%CI 0.638-0.893).

CONCLUSIONSHMGB1 may play a role in the diagnosis of pediatric acute appendicitis.

To prepare the derivatives of salicylic acid-g-chitosan and study their synergistic and complementary actions, the synergism of anti-inflammatory action of the derivatives was investigated with the experiments of xylene-induces mice ear edema, the analgesic activities by the tartaric emetic-induced mice twist test and the hot-plate test, and the complementary effects between salicylic acid and chitosan through morphological changes of stomach mucous membrane of rat, separately. The anti-inflammatory activities of salicylic acid-g-chitosan derivatives for anti-inflammatory activities were more potent than that of salicylic acid and chitosan and dexamethasone cream in external use, and more potent than that of aspirin orally. However, immediate analgesic activity of the derivatives was lower than that of aspirin and persistent activity was similar as that of aspirin. And the stomach mucous membrane morphology change of the derivatives was much milder than that of aspirin. The salicylic acid grafted chitosan derivatives showed synergistic and complementary effect on the anti-inflammatory and analgesic activities and so on.
