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.

We performed the nursing strategy as postural drainage, condition monitoring and conscious assessment intra-and post-operation. ·CONCLUSION: It is the critical for this kind of surgery that both circulating nurse's high-skilled cooperation to the connection and operation of the navigation system, to treat with complication during the surgery, and scrub nurse's sufficient preparation of surgical instruments and consumables, proficient equipment delivery, meticulous management, use and maintenance of equipment.

Objective · To investigate effect of fucoidan on autophagy, migration and invasion in human multiple myeloma U266 cells. Methods · The U266 cells treated with fucoidan were cultured in vitro. The formation of autophagosomes was observed by transmission electron microscopy (TEM). Transwell assay was used to evaluate the effect of fucoidan on migratory and invasive abilities of U266 cells. The protein levels of LC3-Ⅱ/LC3-Ⅰ, Beclin-1, P62, MMP9, CXCR4, p-AKT/T-AKT, p-mTOR/T-mTOR were detected by Western blotting. MMP9 concentration in the culture medium was examined by ELISA. Results · ① Autophagosomes increased in fucoidan-treated cells compared with control group under TEM. ② Migratory and invasive abilities were inhibited by fucoidan in a dose-dependent manner, which were suppressed by chloroquine. ③ Western blotting demonstrated that expression of LC3-Ⅱ/LC3-Ⅰ, Beclin-1 and MMP9 increased in fucoidan-treated cells, while P62, CXCR4, p-AKT/T-AKT and p-mTOR/T-mTOR decreased compared with control group. ④ The result of ELISA showed that MMP9 concentration in the culture medium of fucoidan-treated cells significantly decreased. Conclusion · Fucoidan induces autophagy and inhibits migration and invasion in U266 cells.

BACKGROUND: Sepsis is a common complication of infections, burns, traumas, surgeries, poisonings, and post-cardiopulmonary resuscitation. The present study aimed to investigate prognostic value of CD4+CD25+ regulatory T cells (Treg) in peripheral blood of patients with sepsis. METHODS: Periphery blood from 28 patients diagnosed with sepsis was collected on day 1 and 7 after hospitalization in the ICU of Shanghai Changzheng Hospital between December 2013 to April 2014. The blood was used for analyses of Treg ratio using flow cytometry and for analyses of blood routine test, C-reactive protein (CRP), bilirubin, procalcitonin (PCT), and coagulation. APACHE II and sequential organ failure assessment (SOFA) scores were also investigated. The results were compared between two outcome groups of survival or death to evaluate prognostic value for sepsis. RESULTS: The patients had an average age of 60.36±15.03 years, APACHE II score 16.68±7.00, and SOFA score 7.18±3.78. Among the 28 patients, 12 had severe trauma (42.9％), 10 had septic shock (35.7％), and 9 (32.2％) died. The median ratio of Tregs was 2.10％ (0.80％, 3.10％) in the survival group vs. 1.80％ (1.15％, 3.65％) in the death group (Z=–0.148, P=0.883) on day 1; however it was significantly changed to 0.90％ (0.30％, 2.80％) vs. 5.70％ (2.60％, 8.30％) (Z=–2.905, P=0.004). CONCLUSION: With better prospects for clinical application, dynamic monitoring of Tregs ratio in peripheral blood has potential value in predicting prognosis of sepsis.

BACKGROUND:Cyclin A2 is a key regulator of cellcycle. Location and expression of cyclin A2 in neonatal mouse myocardium is not clear.
OBJECTIVE:To observe the location and expression of cyclin A2 in neonatal mouse cardiomyocytes and its relationship with the exit of cardiomyocytes from cellcycle.
METHODS:Neonatal mice were kil ed to take myocardial tissues at 0, 3, 7, 14 and 28 days after birth. Western blot were used to detect the expression of cyclin A2, proliferating cellnucleus antigen and Phospho-histone H3. Immunohistochemitry detection was used to detect the location of cyclin A2 and expression of proliferation cellnucleus antigen at different time after birth.
RESULTS AND CONCLUSION:Western blot showed the decrease of cyclin A2 after birth til disappeared at day 4 (P=0.001). Cyclin A2 located mainly in the nucleus after birth and exported to the cytoplasm at day 14, and basical y disappeared at day 28. Proliferating cellnucleus antigen showed gradual y decreased tendency after birth. Mitosis specific marker, Phospho-histone H3, exhibited a gradual decrease after birth, which was consistent with cyclin A2 in expression intensity.

Objective To explore the impact factors for post-thaw embryo survival rate and clinical pregnancy rate in frozen-thawed embryo transfer program. Methods The clinical data of 573 cycles of frozen-thawed embryo transfers were retrospectively analysed. Groups were divided according to the pre-freeze embryo quality, pre-freeze embryonic developmental stage, frozen-thawed embryo quality and cryopreservation technique, respectively, and post-thaw embryo survival rates and/or clinical pregnancy rates were compared among groups. Results The clinical pregnancy rate of high quality pre-freeze embryo was significantly higher than that of low quality pre-freeze embryo (31.8% vs 20.0%) (P< 0.05). There was no significant difference in the post-thaw survival rates and clinical pregnancy rates between embryos frozen at day 2 of ferrtilization and those frozen at day 3 of ferrtilization(79. 1% vs 82.9% and 25.5% vs 31.2%, respectively) (P>0.05). The clinical pregnancy rates of the transfer cycles only with fully intact embryos and with mixed embryos were significantly higher than that only with partially damaged embryos(36.7% vs 24.1% and 29.2% vs 24.1%, respectively)(P<0.05). The post-thaw survival rate and post-thaw high-quality embryo rate were significantly higher in those processed with modified cryopreservation technique than in those processed with original cryopreservation technique (82.0% vs 66.3% and 50.0% vs 27.5%, respectively)(P<0.05). Conclusion Pre-freeze embryo quality, post-thaw embryo survival rate and post-thaw embryo quality have a positive correlation to subsequent clinical pregnancy rate. Favorable cryopreservation technique may ensure the success of post-thaw embryo recovery and transfer.
