Objective To explore a simple, effective and stable method for the isolation and purification of Kupffer cells from rat liver, enabling further study on the structure and function of these cells in vitro. Methods After laparotomy, a catheter was inserted into the portal vein and secured with artery clamp. Then, the rat liver was perfused and digested with solution Ⅰ and solution Ⅱ containing 0.05% collagenase Ⅳ respectively. The cell suspension was centrifuged with isopycnic sedimentation in a two-step Percoll gradient to harvest Kupffer cells. The isolated Kupffer cells were purified by selective adherence after 30 min of cultivation, and identified by evaluation of phagocytosis of India ink and peroxidase staining with DAB through light and electron microscopy. Results It was verified that the viability of isolated Kupfffer cells was more than 90% through Trypan blue staining. Those Kupffer cells could attach to plastic quickly and phagocytose ink, and had the appearance of "fried eggs" in positive peroxidase staining with a purity of 95%. Under the light microscopy, the appearance of newly isolated Kupffer cells was round with uniform shape and size. After two days of culture, Kupffer cells appeared to distend with irregular or stellate shape. The typical features were observed in the transmission electron micrographs. There were numerous pseudopods and occasional cup-like indentations in the cell membrane of Kupffer cells. The cytoplasm contained numerous types of lysosomes and other phagocytotic vesicles. Conclusion The method for isolating and culturing Kupffer cells in this study is effective and stable, and the biological characters are preserved in the cultured cells.

Objective: To introduce recent research progress in anti-diarrhea with single Chinese herb and its effective compo-nents. Methods:The references on anti-diarrhea with single Chinese herb and its effective components in recent years were reviewed and analyzed. Results:The researches on anti-diarrhea activity and possible mechanism of single Chinese herbs, such as Terminalia chebula Retz, Fructus mume, Radix Puerariae and Pulsatilla chinensis ( Bunge) Regel, were reviewed. Conclusion: At present, the researches on anti-diarrhoea with single Chinese herb and its effective components have made some progress, while further and wider researches are still needed to explore the underlying mechanisms.

Overnutrition during the early postnatal life,a critical time window for growth and development,may induce metabolic syndrome later in life,including overweight/obesity and insulin resistance.The important target organs of insulin,such as liver,adipose tissue,skeletal muscle,and central nervous systems show insulin resistance.The involved mechanisms include abnormality of insulin signal pathway,increment of free fatty acid and some adipocytokines,oxidative stress,maladjustment of orexigenic and anorexigenic neuron,modifications of the hypothalamic-pituitary-adrenal glucocorticoid axis as well as epigenetic,etc.Hence,overnutrition should be avoided during the early postnatal life,so as to decrease the risk of developing long-term insulin resistance.

Objective To investigate the relationship between serum uric acid level and the severity of pregnancy induced hypertension (PIH) in pregnant women with hypertension.MethodsFrom January 2016 to July 2016 in our hospital for treatment of 100 cases of patients with pregnancy induced hypertension, as PIH group, divided into severe hypertension group (33 cases), moderate PIH group (33 cases) and mild PIH group (34 cases), then select 100 cases of normal pregnant women normal pregnancy group.The serum uric acid levels were measured and the results were analyzed.ResultsThe average serum uric acid levels in PIH group (359.75+89.23) mol/L was significantly higher than the control group (188.24+54.54) mol/L in PIH group, the average level of serum uric acid in severe, moderate and mild degree is decreasing, respectively (449.32+81.11), (352.89+76.41), (288.76+59.58) mol/L, a statistically significant difference between the groups (P<0.05).ConclusionThe detection of serum uric acid level in pregnant women can effectively determine the degree of pregnancy induced hypertension in pregnant.

ObjectiveTo discuss treatment experiencing in femur periprothetic fracture after hip arthroplasty in pre-, intra- and post-surgery.Methods From March 2005 to May 2011, 27 patients (11 males, 16 females) aged ＞75 years with femur periprothetic fracture after hip replacement were studied. The mean time from primary hip replacement to femur perprosthetic fracture was 63 months(ranging from 7 to 83 months). According to vanconver classification, type A applying steel wire of character for 8 bind technique was 5 cases, type B applying prolonging stem technique locking compress plate (LCP)technique surrounding instrument technique was 19 cases and type C applying bone graft and plate fixation technique was 3 cases. All patients were followed up from 9 to 25 months (average, 16 months). The results of treatment were evaluated by Harris score and X rays. Results Bony heal was obtained in 22 patients and was not obtained in five cases among whom bony heal occurred in 3 cases and 2 patients could only keep prothetic and limb stable after receiving the bone graft once more. Walking was free in 14 cases,9 cases needed assistant walking instrument,and only 4 cases stayed in the bed freely. Harris score for last follow-up was 52 to 93 (mean 76).Conclusions Based on the patient general status, the fracture types and practical and stable principle, the effective methods can get good results in the treatment of femur periprosthetic fracture in aged patient.

ObjectiveTo research in the essence of the caring experience of caregiver for children with eye enucleation, to find out the caring experience and caregiver's needs, to give them physical and mental nursing in order to make them cooperate with us and implement effective treatment to children.Methods12 caregivers for children with eye enucleation were given semi-structured interviews. The materials were analyzed, putted in order, and themes were got.ResultsThrough deep interview of 12 caregivers, five titles were summarized:overburdened psychology, limited schedule, requirement of health information, overload economic burden, to return and rebuild.ConclusionsThe results could help nurses to give more correct health education and psychological care to caregivers. Then caregivers can cooperate with nurses to give effective treatment to children, thus life quality of children with eye enucleation will be improved a lot.

Objective To seek for the best clinical nursing pathway for early limbs activity of patients with high-risk hemiplegia in the department of cerebral surgery and to reduce limbs paralysis and improve their life quality.Methods Patients(112 cases)with high-risk bemiplegia in the department of cerebral surgery from January to December in 2007 were set as the experimental group.They took part in limbs early activity on the first day on admission with application of clinical nursing pathway.Patients(89 cases)of the same kind who took part in limbs activity from January to December in 2006 were set as the control group.The two groups were compared with Brunnstrom scale beth on admission and discharge.Results The Brunnstrom grade of upper limbs,hands and lower limbs of the experimental group was evidently higher than that of the control group(P＜0.05).Especially the isolated movement and coordination ability of the hands significantly increased(P＜0.01). Conclusions Early limbs activity with clinical nursing pathway for patients with high-risk hemiplegia in the department of cerebral surgery could reach the aim of recovery of limbs functional activity.

Objective To investigate the effect of nursing interventions on the quality of life after radiotherapy in nasopharyngeal cancer. Methods 56 patients with nasopharyngeal cancer who received radiotherapy were randomly divided into control group and intervention group. All the patients were given conventional nursing interventions, and those in the intervention group were given accurate evaluation, enhanced psychological guide, reasonable dietary guide, and special nursing for preventing and treating complications. All the patients were evaluated by using quality of life questionnaire core 30 items(QOL-C30). Results The scores of the dimensions of somatic function,psychological function, social function and material life after interventions in the intervention group were significantly higher than those in the control group (P＜0.05 ). Conclusion Nursing interventions can improve the quality of life, and the therapy can be completed smoothly.
