Objective To investigate whether the splenic metastasis of B16 melanoma cells in C57BL/6 mice occur through the blood.Methods Cultured B16 melanoma cells were collected,adjusted into 1?10~7/ml and inoculated into the left armpit of C57BL/6 mice,200 ?l each.After 15 days,the mice were sac- rificed and metastasis was examined in various tissues and organs by HE stain.1.5 % Evan Blue(EB),2 ml/kg, was administered to normal C57BL/6 mice through the tail vein,and the region stained blue was compared with that of metastasis.Results All of 12 mice inoculated were burdened with melanoma.Splenic metastasis occurred in 9 of them,among which 3 were accompanied by lung metastasis,and all of 9 mice showed differ- ent degree of local lymph node metastasis.The dorsal 1/4 part of the positive spleen was stained black by the metastatic tumor cells.Under the microscope,distribution of the metastatic tumor cells in the spleen was scat- tered,their growth inhibited,and maturation accelerated.The region stained blue by EB also located at the dorsal 1/4 part of the spleen,which was almost the same as the positive part of metastasis.Conclusions Metastasis of B16 melanoma cells in C57BL/6 miee occurs earlier in the spleen than in other organs,and this metastasis is achieved most possibly through the blood.

Objective To assess compliance in liver transplant recipients,ascertain related factors,and help clinical nunrses take measures to improve compliance. Methods Questionnaires including social demo-graphic variables and questionnaire about compliance after liver transplant,were used to investigate 54 liver transplant recipients whose post transplant time>6 months.Results Liver transplant recipients had good compliance to immunosuppressive medication,scored(3.67±0.51),and health lifestyle,scored(3.30±0.44),but relatively poor compliance to follow-up.scored(3.05±0.89)and self-monitoring,scored(2.00±0.89).The main factors influencing the compliance were average monthly per capita family income(P<0.01)and post trans-plant time(P<0.01).Conclusions The importance of compliance to follow-up and self-monitoring should be emphasized in health education to the recipients and more attention should be paid to those re-cipients with lower income or longer post transplant time.

Objective To observe the curative effect about heavy abdomen type of anaphylactoid pur-pura treated by Methylprednisolone associate with Heparin. Methods Randomly divided eighty three children with heavy abdomen type of anaphylactoid purpura who treated in department of pediatrics of the first hospital affiliated to Kunming medical college from January, 2006 to december, 2007 into group A (treated by Hydro-cortisone) and group B (treated by Methylprednisolone) and group C(treated by Methylprednisolone associate with Heparin). Group A treated by mainline Hydrocortisone dose of 5～8 mg/kg body weight once a day,mixed into 100ml 5% glucose injection, after 7～14 days later, instead of take orally Predisone tablet and de-grees dose by gradually. Group B treated by mainline Methylprednisolone dose of 2～4 mg/kg body weight once a day, mixed into 100ml 5% glucose injection, after 7～14 days later, instead of take orally Predisone tablet, and group C treated by Methylprednisolone by oneself (dose like group B) associate with mainline Hep-arin (dose of 0.25～0.75 mg/kg body weight once a day, mixed into 100ml 5% glucose injection) 7～10 days. Observe clinic symptomatic like as tetter, bellyache, entron hemorrhage when treatment of every group. Contrast reiteration rate of anaphylaetoid purpura, and the period of urine test get hack normal which cases with kidney tamper. Contrast these medication' s side effect such as resort of natrium and water, elec-trolyte turbulence, hemorrhage and so on. Results Group C (treated by Methylprednisolone associate with Heparin) is better then group A (treated by Hydrocortisone) and group B (treated by Methylprednisolone by oneself) in eliminate tetrer and release bellyache. The less period of group C need to treatment entron hemor-rhage and urine test get hack normal. And thereiteration rate is less of group C than group A and group B.Conclusion Methylprednisolone in association with Heparin to treat heavy abdomen type of anaphylactoid purpura is better than hydrocortisone and Methylprednisolone by oneself in controling symptom, reduing reiter-ation rate and more less side effect. So methylprednisolone in association with Heparin to treat of heavy ab-domen type of anaphylactoid purpura is a ideal project.

Young women affected by education and career delay the childbearing period,which results in reduced fertility.With the two-child policy completely opening,more and more elderly women have demands for pregnancy and the need of assisted reproductive technology (ART) increases day by day.However,the ART treatment faces with a series of medical and ethical problems.For example,the pregnancy rate of aged women is low but the abortion rate is high;and the incidence of pregnancy complications and fetal chromosomal abnormality increases significantly.In this regard,it can solve these problems through limiting the women's age,choosing the donated eggs,strengthening the counseling for elderly infertile women before ART treatment,paying attention to the psychological problems and applying the genetic screening technology before implantation.

Waldenstrom macroglobulinemia (WM) is a malignant B-cell lymphoproliferative disorder, which still remains incurable. Reports on the latest research progress of WM were presented in the 58th American Society of Hematology (ASH) Annual Meeting, covering the theoretical and clinical researches of this disease. In basic research, mechanism of ibrutinib resistance has been further explored. The application of modern technologies, such as next-generation sequencing, has promoted the pathogenesis and prognosis of WM. In clinical research, retrospective analyses of traditional treatment provide new theoretical foundation in the choice of regimen, while clinical trials on new drugs including BGB-3111 and oprozomib may improve the therapy. The research advances in WM will be summarized in this paper.

Objective To explore the activity of daily living in patients with schizophrenia and its related factors. Methods 200 patientswith schizophrenia were investigated with the questionnaire about general condition, the Positive and Negative Syndrome Scale (PANSS)and Activity of Daily Living Scale (ADL) when hospitalized. The relationship between the scores of ADL and sexuality, age, education level,marital status, profession before the disease attacking, household, disease type, course of the disease, frequency of attacking and hospitalizationor scores of PANSS was analyzed. Results The score of ADL was significantly above the normal level (t=32.206, P=0.000) in theschizophrenics. The score of ADL was not significantly different among the patients in different gender, education level, marital status, profession,household and the frequency of hospitalization (P>0.05), but was significantly different among the ages (F=3.851, P=0.023) and diseasetype (F=19.793, P=0.000). The score of ADL positively correlated with the course of the disease (r=0.161, P=0.023), frequency of attacking(r=0.396, P=0.000) and the difference value between the numbers of attacking and hospitalization (r=0.425, P=0.000), so as the totaland each factors scores of PANSS (P=0.000), but did not correlated with frequency of hospitalization (r= 0.097, P=0.174). By multiple regressionanalysis, only 3 factors score of PANSS, the frequency of attacking and the difference value between the numbers of attacking andhospitalization entered into the regression equation (F=53.630, P=0.000). Conclusion The patients with schizophrenia generally fall in activityof daily living. The more serious the disease, the more frequent the attacking and the more the difference value between the numbers ofattacking and hospitalization, the poorer the activity of daily living was.

The core-shell nanopaticles of Au@polyvinyl-pyrrolidone ( PVP) with uniform size and controllabe shell-thickness were prepared by hydrothermal method. The core-shell nanoparticles could be assembled to be the monolayer array on Si substrate relying on the dispersion of core-shell nanoparticles arising from PVP shell. The malachite green ( MG ) absorbed by H-bond could be detected on the array under the electromagnetic enhancement of inner-core Au nanoparticles. Under the conditions of the optimum shell-thickness of Au@PVP and the appropriate absorbed time of MG, the detection of MG could be realized in the linear range from 1 × 10-10 mol/L to 1 × 10-5 mol/L with the correlation coefficient ( R2 ) of 0. 98. The detection limit was 10-12 mol/L. This method was applied to the determination of MG in tilapia fish fillets of Xiagang market. No MG was found in this real sample. The spiked recoveries of the sample ranged from 70. 8% to 126. 0%. This method is simple and accurate, and can be used for detection of MG in the fish.

Aim To explore the effect of picrodideⅡ on the expressions of Caspase-3 and poly ADP-ribose polymerase (PARP) in brain tissue following cerebral ischemic reperfusion injury in rats.Methods The middle cerebral artery occlusion reperfusion models were established with intraluminal thread methods in rats. PicrodideⅡ (10 mg·kg~(-1)) and salvianic acid A sodium (10 mg·kg~(-1)) were injected from tail vein for treatment. The neurological function was evaluated with Bederson's test and the cerebral infarction volume was observed with tetrazolium chloride (TTC) staining.The brain structure was observed by hematoxylin-eosin (HE) staining and the apoptosis was counted by TUNEL immunofluorescence assay. The expressions of Caspase-3 and PARP were detected with immunohistochemical and enzyme linked immunosorbent assay.Results After ischemia 2 h and reperfusion 22 h, the rats showed neurological function deficit and cerebral infarction in ischemic hemisphere. The expressions of Caspase-3 and PARP and the number of apoptotic cells in brain tissue increased compared with those in the sham operative group (P <0.05). In picroside and salvianic acid A sodium groups, the Bederson's scores and cerebral infarction volume, the expressions of Caspase-3 and PARP and the number of apoptosis cells were lower than those in the negative control group (P <0.05). While there was no significant difference in five indexes metioned above between picroside group and salvianic acid A sodium group (P >0.05).Conclusion PicrosideⅡ might reduce the expressions of Caspase-3 and PARP to inhibit the neuronal apoptosis induced by cerebral ischemia reperfusion injury and improve the neurological function of rats.

Objective To evaluate the curative effect of urokinase combined with low molecular heparin sodium in managing arteriovenous fistula embolism. Methods Toally 48 patients with arteriovenous fistula embolism treated from January 2014 to October 2015 were selected for the study, where 22 were assigned into control group and 26 as trial group according to the registration time. The former group were treated with urokinase and the latter with urokinase combined with low molecular heparin sodium. The rate of recanalization, the rate of thrombosis recurrence, and the adverse reactions were compared between the two groups. Results The recanalization rate in the trial group was higher than that in the control group (P<0.05). The rate of thrombosis recurrence in the trial group was significantly lower than that the control group. There was no statistical difference in adverse reactions between the groups. Conclusion The thrombolytic effect of urokinase combined with low molecular heparin sodium is superior to that of urokinase alone, with a higher rate of recanalization.
