Objective To study the tolerance to 188Re-1-hydroxy-1 ,1-ethylidene disodium phosphonate(HEDP) in patients with bone pain caused by osseous metastases. Methods Thirty-one patients(10with prostate cancer, 9 with breast cancer, 3 with lung cancer, 5 with liver cancer, 2 with rectal cancer, 1with esophageal cancer and 1 with renal cancer) received a single injection dose of 188Re-HEDP. The patients were divided into four groups according to the injection dose: 20 MBq/kg (6 patients), 30 MBq/kg(6 patients), 40 MBq/kg (9 patients), and 50 MBq/kg (10 patients). Haematological toxicity (WHO grading) of grade Ⅲ- Ⅳ was considered unacceptable. Vital signs and adverse effects after injection were recorded for 8 weeks. Blood counts were measured weekly during a period of 8 weeks. Biochemical parameters and electrocardiogram were assayed at week 4 and 8. Statistical analysis was performed for per-protocol (pp) population (t-test). Results Twenty-seven patients belonged to PP population with 5 in the group of 20 MBq/kg, 5 in the group of 30 MBq/kg, 8 in the group of 40 MBq/kg and 9 in the group of 50 MBq/kg.No obvious adverse effects and no significant change of vital signs, electrocardiogram, liver and renal function were found after injection. Alkaline phosphatase was slightly higher than baseline at week 4 and 8 after therapy, but the difference was not statistically significant. In the 20 MBq/kg group, reversible grade Ⅰ leucopenia was noted in 1 patient. In the 30 MBq/kg group, 2 patients showed reversible grade Ⅰ leucopenia including 1 alone with reversible grade Ⅲ thrombopenia. In the 40 MBq/kg group, reversible grade Ⅰ leucopenia and thrombopenia was observed in 1 patient and reversible grade Ⅱ leucopenia and thrombopenia in another patient. In the .50 MBq/kg group, 3 patients showed reversible grade Ⅱ leucopenia. The lowest level of thrombopenia was at week 4(143.5 × 109/L), leucopenia at week 6 (5.4 × 109/L) and anaemia at week 8(t = 3.1325, 3.3156, 3.4917, all P ＜ 0. 05 compared with baseline). At week 8, the mean level of platelet and leucocyte recovered to baseline. "Bounce pain" was found in 2 of 27 patients (7.41%).Conclusions The dose of 20 MBq/kg, 30 MBq/kg, 40 MBq/kg or 50 MBq/kg of 188Re-HEDP do not cause significant side effects on cancer patients with bone metastases, though there is a tendency that the haematological toxicity may increase as the dose of 188Re-HEDP increases.

Primary angiitis of the central nervous system is a rare and difficult entity. Here we represented the clinical and pathological features of a patient with little response to steroid before definite diagnosis. The 50-year-old male had a fluctuating disease course for more than 3 years. He presented visual disorders, seizure, cognitive impairment, hypersomnia, unsteady gait, dysphasia, dysphagia, and incontinence. Magnetic resonance imaging showed multiple, supratentorial and infratentorial abnormal signals, while cerebrospinal fluid and cerebral angiography were normal. Magnetic resonance spectrum showed a decrease of N-acetyl-aspartate. Brain biopsy revealed nongranulomatous lymphatic vasculitis with reactive gliosis, cicatrization, demyelination and focal hemorrhages.

Objective To investigate the social participation in patients with primary malignant bone tumor in lower extremity after surgery,and to explore the influencing factors.Methods The descriptive and correlative design was used.Reintegration to normal life index(RNLI) was used to assess the social participation of 94 patients.Results The average score of RNLI in 94 patients was (70.62 ± 19.33)/110 after surgery.The social participation was influenced by age,marital status,postoperative complications,postoperative time and rehabilitation.Marital status and rehabilitation explained 53.3％ of the total variance of RNLI.Conclusions The patients' social participation is decreased.Nurses should take targeted interventions to improve the social participation of patients and promote the patients return to society.

To study the pharmacokinetic process of Danshensu in cerebal ischemia injury model rats and the correlation with its anti-cerebral ischemia effect. In this study, the middle cerebral artery occlusion (MCAO) model was established, in which all of the rats were intravenously injected of Danshensu at a single dose of 40 mg x kg(-1). The HPLC-DAD method was applied to determine the plasma concentration of Danshensu at different time points and draw the drug-time curve. Meanwhile, the superoxide dismutase (SOD) and the lactate dehydrogenase (LDH) activity were determined to draw the time-effect curve. The DAS 3.2. 6 software was used to process the data, analyze their correlation, compare the pharmacokinetic difference between model and normal rats after the administration of the same doses of Danshensu and the changes in pharmacodynamic indicators of model rats after the administration, and evaluate the effect of Danshensu in treating the cerebral ischemia disease. According to the results, the pharmacokinetic processes of Danshensu in the cerebral ischemia-reperfusion and normal rats were consistent to the two-compartment model. The main pharmacokinetic parameters were: t1/2alpha were (0.267 +/- 0.026), (0.148 +/- 0.020) h;t1/2beta were (1.226 +/- 0.032), (1.182 +/- 0.082) h; AUC0-infinity were (42.168 +/- 4.007), (26.881 +/- 1.625) mg x L(-1) x h. After the cerebral ischemia-reperfusion, the activity of SOD decreased and the activity of LDH increased. Danshensu could inhibit the decrease in the SOD activity and the increase in the LDH activity within a certain period of time. This indicated that Danshensu could stay longer in cerebral ischemia-reperfusion rats than in normal rats and eliminated more slowly, which reflected the rationality of Danshensu in the clinical treatment of cerebral ischemia diseases. Danshensu's effect against the cerebral ischemic injury may be related with its level in vivo. Its plasma concentration is positively related to the SOD activity and negatively related to the LDH activity.

OBJECTIVETo investigate the use of a 32P application device (AD) in the treatment of condyloma acuminatum (CA) in the rectum, and to compare its clinical effect with that of the microwave therapy.

METHODSThis study included 107 cases of CA in the rectum, 99 males and 8 females, aged 21-58 (33.6 +/- 9.4) years. Forty-six of the patients (the AD group) were treated with a self-made 32P application device, which, as a tube-shaped carrier of radionuclide 32P colloid, was fixed in the rectum at the diseased part for medication at 4.9-8.2 Gy for 3-5 hours once and 1-2 times a week. The other 61 (the microwave group) were treated by microwave burning under local anesthesia. Both groups of patients were followed up for over 3 months for comparison of the therapeutic results and observation of the stability and reliability of the 32P application device.

RESULTSThe rates of cure, reoccurrence and adverse reaction were 84, 8%, 13.0% and 8.7% in the AD group, compared with 40.3%, 55.7% and 75.4% in the microwave group, with statistically significant differences between the two groups (P < 0.01).

CONCLUSIONThe 32P application device, with its advantages of low cost, easy operation, good effect, high safety and reliability, low recurrence, fewer adverse events and good acceptability, is highly valuable for the treatment of CA in the rectum.

Objective To analyze the epidemic characteristics of hand-foot-mouth disease (HFMD) in Jiangsu province.Methods We downloaded the case-data of HFMD in Jiangsu province during 2009-2011 from the Chinese National Notifiable Infectious Disease Reporting System,and made a comprehensive analysis on the epidemiological features of it with descriptive epidemiological methods and retrospective space-time permutation scan statistics.Results A total of 285 414 cases were reported in Jiangsu,from 2009 to 2011,with an annual incidence of 122.66 per 100 000.There were 3686 severe cases in the 3 years accumulatively,accounting for 1.29％ of the total.Proportion of the cases being 5 years old or even younger was 93.64％.Scatteredly living children accounted for 64.08％ of the total cases and 78.65％ of the severe cases,respectively.The epidemics of HFMD were visible in each city of Jiangsu province,with a lowest annual incidence rate of 44.02 per 100 000 and a highest one up to 202.90 per 100 000.Regions as Suzhou,Nanjing,Wuxi had the highest incidence in the province,with cases in these three areas occupying almost 40％ of all.The numbers of severe cases in Suqian and in Yancheng cities increased by 339.22％ and 328.33％ in 2011 compared to in 2010,respectively,and the rates of increase in these two cities were much higher than those in the other regions.Two peaks of incidence were observed every year,with the highest occurring between April and June and the second occurring in November.The spatial-temporal distribution of HFMD was not random in Jiangsu province,from 2009 to 2011.Clusters for general cases in August and 7 clusters for severe cases were detected,respectively.12 359 cases of HFMD were laboratory confirmed in the said 3 years,including 10 414 common cases and 1945 severe cases.EV71 and CoxA16 accounted for 43.49％ and 37.07％ of common cases,respectively.In terms of the severe cases,the ratios were 80.82％ and 5.96％,respectively.Conclusion HFMD was highly endemic in Jiangsu province,and the situation of prevention and control for it is still grim.Scatteredly living children of 5 years old or younger were the major population at risk,and the epidemic in different regions and seasons was different.EV71 and CoxA16 were the major etiologic agents,but the etiologic constitute showed seasonal changes.

OBJECTIVETo study CXCR3 and CCR5 chemokine receptor expression in spleens of patients with primary immune thrombocytopenia (ITP) and its clinical significance.

METHODSThe splenectomy specimens from 10 ITP patients (ITP group) and 8 patients with traumatic splenic rupture (normal control group) were studied. Immunohistochemistry (IHC) was used to study the positive rate of CXCR3 and CCR5. Western blot was performed to detect CXCR3 and CCR5 protein expression, while real-time polymerase chain reaction (RT-PCR) was conducted to analyze their mRNA expression.

RESULTSThe positive rate of CXCR3 and CCR5 were both higher in ITP group (90% and 100%, respectively) than those in control group (75% and 87.5%, respectively)(P < 0.05). The differences were statistically significant (P < 0.05). Protein and mRNA level of CXCR3 in ITP group were 3.0 and 3.5 times as high as those in control group, respectively. Those of CCR5 in ITP group were 1.2 and 1.7 times as high as those in control group, respectively.

CONCLUSIONHigh expression of CXCR3 and CCR5 may play a part in the splenic immune disorders in patients with ITP.

Objective To explore the effect of hydrogen sulfide (H2S) on the expression of survivin in PC12 cells and the neuroprotective function of H2S on PC12 cells.Methods Different concentrations of sodium hydrosulfide (NaHS) were used to treat the PC12 cells at different times.Dose-effect (50-800 μmol/L) and time-effect (0-180 min) on the expression of survivin were evaluated by Western blotting.Cell viability was tested by using cell counter kit-8.Results NariS treatment at the concentrations from 50 to 200 μmol/L for 30 min could up-regulate the expression of survivin in a dose dependent manner,however,when the concentration of NariS was above that,the expression of survivin decreased gradually;when the concentration of NariS reached 800 μmoi/L,the expression level of survivin was lower than the normal level.Treatment with 400 μmol/L NariS within the range of 0-60 min could promote the expression of survivin in a time dependent manner,but with the extension of time,the expression of survivin was declined.On the other hand,400 μmol/L NaHS preconditioning could enhance the expression of survivin promoted by CoCl2 and reduce the injuries of PC12 cells induced by CoCl2 to increase the cell viability.Conclusion H2S increases the expression ofsurvivin in a dose and time dependent manners at certain degree,which may be related to the protection of PC12 cells against chemical hypoxic damage.
