OBJECTIVE: To investigate the regularity and characteristics of moxifloxacin-induced torsade de pointes (TDP), and to provide reference for rational use of drugs. METHODS: A total of 5 reported cases of moxiflixacin-induced TDP in recent 10 years were analyzed retrospectively. RESULTS: Of 5 cases, 2 cases were male and 3 female with mean age of (81?7) years. 5 patients suffered from organic heart disease. The onset time of TDP by oral administration was later than that by intravenous administration. Mean QTc intervals was (567?35) ms at attach period and the time recovered to base level (18?15) h. Potassium, magnesium, and sodium were kept at normal level at attach period. CONCLUSION: Clinical physicians and pharmacists should pay attention to moxifloxacin-induced TDP.

Esophageal cancer is one of the most common malignant tumors in clinic, and its morbidity and mortality are always high. Staging is the main basis for comprehensive treatment and prognosis evaluation. Accurate staging is essential for proper diagnosis, individualized treatment and good prognosis. Related technologies of endoscopic ultrasonography can determine the depth of tumor invasion and local lymph node metastasis, which makes the diagnosis of esophageal cancer more accurate, and plays an increasingly important role in the diagnosis and treatment of early esophageal cancer.

Objective: To investigate the association of polymorphisms of related genes in folic acid metabolic pathway and the tumor candidate genes with the survival of gastric cancer patients treated with capecitabine combined with paclitaxel. Methods: Ninety-three patients with pathological diagnosis of gastric cancer were treated with capecitabine plus paclitaxel-based chemotherapy. The gene polymorphisms of tumor necrosis factor ( TNF) A308G (rs1800629), methylenetetrahydrofolate reductase ( MTHFR) C677T (rs1801131) and A1298C (rs1801133), methionine synthase ( MTR) A2756G (rs1805087) and methionine synthase reductase ( MTRR) A66G (rs1801394) were detected by TaqMan-MGB probe typing method. The median survival time (MST) of patients with different genotypes was compared, and the effects of various factors on the prognosis were evaluated. Results: The median follow-up period was 29.6 months. The MST of 93 patients was 34.93 months. The MST of patients with MTHFR 1298CA and 1298CC were 47.50 and 22.91 months, respectively. The log-rank test revealed that the polymorphism of MTHFR 1298C/A had marginally significant correlation with the survival of patients (χ2=3.447, P=0.062), and other gene polymorphisms were not associated with the survivals. The gender, drinking and operation were the major prognostic factors for gastric cancer patients receiving chemotherapy. Conclusion: Detection of MTHFR 1298CA polymorphism may predict the survival of gastric cancer patients receiving chemotherapy of capecitabine combined with paclitaxel.

OBJECTIVE: To evaluate the relative factors influencing olfactory dysfunction in patients with chronic rhinosinusitis (CRS). METHOD: Visual analogue scale (VAS) was applied to measure the severity of olfactory dysfunction of 270 patients with CRS. Patients were divided into two groups, one was that the quality of life (QOL) of patients was affected by olfactory dysfunction (VAS > 5), the other was that without QOL affected by olfactory dysfunction (VAS ≤ 5). The association between age, gender, nasal polyps, allergic rhinitis, smoking history, early nasal surgery history and other clinical factors, and serum total IgE level, peripheral blood eosinophil count, peripheral blood mononuclear cell count and olfactory dysfunction was analyzed. RESULT: The number of patients with nasal polyps, allergic rhinitis, previous nasal surgeries, the level of serum total IgE, and the severity of edema were significantly increased in patients with impaired QOL associated with olfactory dysfunction (P < 0.05). Sex distribution, age, smoking history, deviation of nasal septum, eosinophil and mononuclear cell count did no statistically differ between the groups with and without impaired QOL associated with olfactory dysfunctions (P > 0.05). Serum total IgE increased (OR = 1.003, P < 0.01) and severe edema (OR = 2.483, P < 0.01) were the risk factors for the impairment of olfactory function, more notably for edema; whereas previous nasal surgeries was a protective factor (OR = 0.408, P < 0.01). CONCLUSION Sever edema and increased serum total IgE are risk factors, whereas previous nasal surgeries history is a protective factor for the olfactory dysfunction.

Objective To investigate the effect of baicalin on inflammatory factors and oxygen free radical metabolism in patients with traumatic shock.Methods 38 patients with traumatic shock were treated with baicalin 200mg intravenous injection when admitted to hospital.Before and 1 h after treatment,TNF-α,IL-6,IL-8,MDA and SOD were measured in blood.Results Compared with before treatment,TNF-,IL-6,IL-8,and MDA levels were decreased after treatment (t =7.32,6.12,20.21,16.10,all P ＜ 0.05),while SOD activity was significantly increased (t =1.69,P ＜ 0.01).Conclusion Baicalin could inhibit the production and release of inflammatory factors TNF-α,IL-6,IL-8 in patients with traumatic shock,reduce the damage of oxygen free radicals to the cells.Early treatment with baicalin had protective effect on patients with traumatic shock.

[Objective]A new limited contact femoral supracondylar interlocking intramedullary nail(LCFSIIN) was made,which was part of a new custom-made hemi-knee joint,to improve the results of childrens' limb salvage.[Method]A new LCFSIIN was performed and the stress of bolts,intramedullary nails and bone were analyzed by finite dement analysis(FEA) while the bolts were implanted in different angulafions-0?,15?,30?,45?and 60?.[Result]The results of FEA show that the stress of bolts,bone and nails with 15? insertion angles of bolt was the tiniest and well distributed.Stress of bone with 0? insertion angles was more obvious than that with 15?,30?and 45?.The more the angles,the stress of proximal bolt became more obvious and the stress of distal bolt decreasing.[Conclusion]This new LCFSIIN can reduce destruction of biological environment of bone and is easy in use in limb salvage surgery of allograft.
