Objective:To evaluate the safety of dental treatment in pediatric patients with leukemia. Methods:Eighty-nine patients were included and dental treatment was conducted under the condition of neutrophil counts ranging from 3.0?109/L to 10?109/L and platelet counts of more than 50?109/L. Supportive medical care was continued, the patients were monitored for at least one month after dental treatment for bleeding,pain,local and/or systemic infection,fever and other complications. Results:Dental treatments were performed successfully.All patients, except one with delayed wound healing after tooth extraction, recovered uneventfully. Conclusions:As long as the hematological values are within the suggested range, preoperative preparation and supportive medical care are well conducted,dental treatment can be safely performed in pediatric patients with leukemia.

Objective The expression of transforming growth factor beta receptor Ⅰ (TGF?RⅠ) and transforming growth factor beta receptor Ⅱ (TGF?RⅡ) in the synovium and the articular cartilage of patients with osteoarthritis were studied,to explore the possible relationship between the transforming growth factor beta receptor and the pathogenesis and treatment of osteoarthritis.Method The distribution and positive levels of TGF?RⅠ,TGF?RⅡ and TGF? 1 in the synovium and articular cartilage from 26 patients with osteoarthritis and 3 patients with trauma were studied,using Immunohistochemial methods.Results Immunohistochemical staining of TGF?RⅠ showed positive in all synovial samples in patients with osteoarthritis.The positive staining of TGF?RⅠ was found in most synovial lining cells,endotheliocyte and the macrophage in subsynovial layer with osteoarthritis,especially macrophage like synoviocyte.The positive particles were distributed in the cytoplasma.The distribution and staining levels of TGF?RⅡ in synovium and articular cartilage of patients with osteoarthritis were similar to those of TGF?RⅠ.Positive stainings for TGF?RⅠ, TGF?RⅡ and TGF? 1 were found in over half of chondrocytes.Conclusion It is suggested that vehicles of signal trasmission of TGF? are rich in the synovial membrane and cartilage.There is an important effect of TGF? receptor on inhibiting inflammatory process and helping to repair local tissue.

Objective To investigate the morphology and the distributon of thymus dendritic cells (TDCs) in mouse. Methods TDCs in mouse were observed and analyzed by the electron microscopy and the immunohistochemistry with DCs marker (including CD205, CD1a and MIDC 8). Results There were the most TDCs in the boundary area of thymus cortex and medulla, lesser TDCs in the cortex, and the least in the medulla. TDCs made up to 2 per cent of all cells in thymus. On TDCs surface there were many processes which extended into diastema surrounding lymphocytes. The nucleus was irregular in shape and there were intentations. The cytoplasm was electron lucent and there were few organelles without any lysosme. Conclusion It may effectively count TDCs and display their morphological character that TDC be jointly labeled by the diversiform markers and its ultrastructure observed.

Objective To observe the effect of Yanshu compound radix sophora injection on the clinical efficacy of patients after interventional embolization for liver cancer rupture and hemorrhage. Methods Sixty-four patients with hepatic cancer rupture and hemorrhage admitted into Department of Hepatobiliary and Pancreatic Surgery in Wuhan Central Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology to undergo interventional embolization and hemostasis from January 2013 to December 2017 were retrospectively analyzed. According to whether the Yanshu compound radix sophora injection was used or not after surgery, the patients were divided into two groups: the patients in western medicine routine treatment control group (32 cases) were given blood transfusion, drugs for pain relief, stopping vomiting, liver protection and symptomatic treatment; the patients in Yanshu compound radix sophora injection group (32 cases) were given besides the above western medicine routine treatment, Yanshu compound radix sophora injection 20 mL in 250 mL 0.9% sodium chloride intravenous drip was additionally applied, once a day for consecutive 10 days. The times of postoperative using analgesics, antiemetics and the proportions of occurring myelosuppression, liver function damage tumor re-bleeding, and decrease of alpha-fetoprotein (AFP) level were observed in two groups. Results The times of using analgesics and antiemetics in patients of compound radix sophora injection group were significantly less than those in the routine treatment group [times of using analgesics (times): 3.2±1.2 vs. 7.4±1.3, times of using antiemetics (times): 4.1±1.1 vs. 7.2±1.2, both P < 0.05], the incidences of adverse reactions such as myelosuppression, liver function damage, tumor re-bleeding rate and AFP reduction rate in patients of compound radix sophora injection group were significantly lower than those in the routine treatment group [myelosuppression: 28.1% (9/32) vs. 56.2% (18/32), liver function damage: 9.4% (3/32) vs. 21.9% (7/32), tumor re-bleeding: 3.1% (1/32) vs. 9.4% (3/32), AFP reduction: 21.9% (7 /32) vs. 15.6% (5/32), all P < 0.05]. Conclusion Yanshu compound radix sophora injection combined with interventional embolization for treatment of patients with hepatic cancer rupture and hemorrhage can significantly improve the clinical efficacy, reduce the incidence of adverse reactions and protect liver function.
