Objective To evaluate the short-term and long-term effect of comprehensive traditional Chinese medical therapy for regulating spleen and stomach in treating tinnitus. Methods Telephone follow-up was carried out in 333 cases of qualified tinnitus outpatients and inpatients from the First Affiliated Hospital of Guangzhou University of Chinese Medicine admitted from January of 2008 to December of 2014. All of the included patients were treated by comprehensive traditional Chinese medical therapy for regulating spleen and stomach. The degree of tinnitus was evaluated by Tinnitus Effect Questionnaire(TEQ) on the first visit and the last visit and during follow-up, and then the TEQ scores were analyzed by statistical methods. Results On the first visit, the mean TEQ scores were 11.17 ± 3.11. On the last visit, the mean treatment course was 33.64 ± 37.07 days, and the mean TEQ scores were 9.57 ± 3.43; 5 cases were cured, 25 were markedly effective, 79 were effective, 224 were ineffective, and the total effective rate was 32.73%. The interval of the first follow-up to the first visit averaged 32.89 ± 8.53 months, and the mean TEQ scores were 5.35 ± 3.71 during the interval; 20 cases were cured, 21 were markedly effective, 39 were effective, 43 were ineffective, and the total effective rate was 65.04%. The interval of the second follow-up to the first visit averaged 57.48 ± 7.91 months, and the mean TEQ scores were 3.42 ± 3.39 during the interval; 37 cases were cured, 21 were markedly effective, 26 were effective, 39 were ineffective, and the total effective rate was 68.29%. Conclusion Comprehensive traditional Chinese medical therapy for regulating spleen and stomach has certain effect in treating tinnitus, and the long-term effect is satisfactory.

In order to improve the interfacial bonding strength of hydroxyapatite/polyurethane implanted material and dispersion of hydroxyapatite in the polyurethane matrix, we in the present study synthesized nano-hydroxyapatite/polyurethane composites by in situ polymerization. We then characterized and analyzed the fracture morphology, thermal stability, glass transition temperature and mechanical properties. We seeded MG63 cells on composites to evaluate the cytocompatibility of the composites. In situ polymerization could improve the interfacial bonding strength, ameliorate dispersion of hydroxyapatite in the properties of the composites. After adding 20 wt% hydroxyapatite into the polyurethane, the thermal stability was improved and the glass transition temperatures were increased. The tensile strength and maximum elongation were 6.83 MPa and 861.17%, respectively. Compared with those of pure polyurethane the tensile strength and maximum elongation increased by 236.45% and 143.30%, respectively. The composites were helpful for cell adhesion and proliferation in cultivation.

Background and purpose: L-asparaginase (L-Asp) is an important drug in the treatment of childhood lymphoid neoplasms at present, but a lot of adverse reactions of L-Asp were observed. Pegasparaginase (PEG-Asp) is available in China in recent years. This study aimed to explore efifcacy and side-effect of PEG-Asp as ifrst-line treatment in childhood acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL). Methods:A total number of 211 ALL or LBL patients were treated with CCLG 2008 or BFM-90 protocol with PEG-Asp or L-Asp between Apr. 2008 and Mar. 2013;42 patients, among whom, were 35 ALL patients and 7 LBL patients, were treated with PEG-Asp as ifrst-line treatment;169 patients were treated with L-Asp as ifrst-line treatment (including 53 patients treated with L-Asp during induction protocol; with PEG-Asp during consolidate protocol). The clinical outcome and adverse reaction of PEG-Asp with L-Asp were observe and compared. Results: There were 35 ALL patients in PEG-Asp ifrst-line treatment group and the complete remission rate after 1 course of PEG-Asp was 97.1%,however, which was 83.3%of high risk ALL patients. The complete remission rate of 7 LBL patients of PEG-Asp ifrst-line treatment group was 57.1%. There was no signiifcant difference between 2 groups (P>0.05). Thirty-four patients relapsed including 5 patients of PEG-Asp ifrst-line treatment group, 16 patients of L-Asp ifrst-line treatment group and 13 patients treated with L-Asp during induction protocol and with PEG-Asp during consolidate protocol. Thirty-one patients died including 3, 18, 10 patients in 3 groups respectively. Twenty-two patients died of relapse, 4 died without remission, 5 died of complications. There was also no signiifcant difference between 2 groups (P>0.05). The incidence rates of adverse reactions were 47.6% and 63.3% respectively. Anaphylaxis, liver functions abnormalities, blood coagulation abnormalities, gastrointestinal reaction, hyperglycemia and pancreatitis were common in our patients. The incidence rate of anaphylaxis in PEG-Asp as ifrst-line treatment group was lower than other groups (P=0.03). But there was no signiifcant difference been observed in the incidence of other adverse reaction. Conclusion: The short-term efifcacy of PEG-Asp as the ifrst-line treatment in childhood leukemia and lymphoma was satisfactory and the incidence rate of anaphylaxis was lower. However, we will still pay much attention to adverse reaction monitoring of PEG-Asp.

Objective To evaluate the effect on salvage treatment of sudden deafness with comprehensive Chinese medicine therapy. Methods Fifty-three sudden deafness patients failing in conventional western medicine treatment were given comprehensive Chinese medicine therapy, and the salvage treatment followed by oral use of Chinese medicine, intravenous injection of Chinese patent medicine, acupoint injection, ear acupoint plastering, acupoint application, acupuncture, sound healing, and massage. The therapeutic effect and the relief of major accompanying symptoms were evaluated after treatment, and the relationship of disease course with clinical efficacy was also investigated. Results (1) After treatment, 4 cases were cured, 9 were markedly effective, 13 were effective, 27 were ineffective, and the total effective rate was 49.06%. (2) Except for the 2 excluded cases, the major accompanying symptoms such as tinnitus, auricular distress, and vertigo were relieved to various degrees in other cases. ( 3) Twenty-two patients had a course of disease within 14 days, and the total effective rate for them was 72.73%. A total effective rate of 32.26% was achieved in 31 cases with disease course over 14 days. It is indicated that the therapeutic effect for patients with a disease course less than 14 days was superior to that with a disease course over 14 days (P<0.01). Conclusion Comprehensive Chinese medicine therapy exerts inspiring therapeutic effect on salvage treatment of sudden deafness, and earlier intervention results into better effect.
