Objective: To investigate the incidence of coutrast media iodixanol-induced delayed adverse reaction with the risk factors in general clinical practice.
Methods: A total of 20,185 patients with contrast iodixanol were recruited from 95 medical centers in China. The risk factors for adverse drug reaction as hypertension, asthma, previous contrast reaction were assessed;the administrative processes as route, injection manner, lfow rate of injection, prior heating of iodixanol were monitored and the demographic information was documented. The immediate adverse reaction within 1 hour of media administration and the delayed adverse reaction from 1 hour to 7 days after administration were recorded. The risk factors for iodixanol-induced delayed adverse reaction were studied by singlevariate and multivariate logistic regression analysis.
Results: The overall iodixanol-induced adverse reaction rate was 1.52%, of which the immediate reaction was 0.58%and delayed reaction was 0.97%. The major delayed reaction was mild and it mostly happened in skin (0.68%) including rash, pruritus and urticaria. Multivariate logistic regression analysis revealed that male gender (OR=0.71, P=0.036), age (OR=0.82, P=0.001), route of administration (OR=0.21, P<0.001), prior heating of iodixanol (OR=1.44, P=0.036), lfow rate of injection (OR=1.28, P=0.001) and previous contrast reaction (OR=16.04, P<0.001) were the independent risk factors for delayed adverse reactions.

Objective:To observe the effect of Zhen'ai needling method in Nei Jing (Classic of Internal Medicine) on quality of life in patients with allergic rhinitis (AR).Methods:A total of 99 patients with AR who met the inclusion criteria were randomized into a conventional needling group (51 cases) and a Zhen'ai needling group (48 cases).The conventional needling group was treated with acupuncture at Zusanli (ST 36),Hegu (LI 4),Juliao (ST 3),Yingxiang (LI 20),Yintang (GV 29),Shangxing (GV 23) and Baihui (GV 20).The Zhen'ai needling group added acupoints of Zhen'ai needling method {Lieque (LU 7),Shanglianquan [Extra,located at 1 cun above Lianquan (CV 23)] and Tianrong (SI 17)} in addition to points in the conventional needling group.The needles were retained for 30 min.The treatment was performed twice a week.All patients were assessed by total nasal symptom score (TNSS),total ocular symptom score (TOSS) and sino-nasal outcome test-20 (SNOT-20) before and after 15 treatments to evaluate the quality of life.The clinical efficacy was evaluated after 15 treatments.Results:During the treatment,8 cases dropped out in the conventional needling group and 7 cases in the Zhen'ai needling group.There were no significant differences in TNSS,TOSS and SNOT-20 scores between the two groups before treatment (all P＞0.05).After treatment,the total effective rate of the Zhen'ai needling group was 92.7％,versus 88.4％ in the conventional needling group.There was no significant difference between the two groups (P＞0.05).After treatment,there were no significant differences between the two groups in TNSS and TOSS scores (both P＞0.05).The SNOT-20 score of the Zhen'ai needling group was lower than that of the conventional needling group,and the difference was statistically significant (P＜0.05).There were statistical differences between the two groups in the scores of cough and nasal reflux (to the throat) of the NOT-20 scale (both P＜0.05).Conclusion:Both Zhen'ai needling method and conventional acupuncture are effective in the treatment of AR.Zhen'ai needling method has a better effect than conventional acupuncture in improving cough and nasal reflux (to the throat) in AR patients.

OBJECTIVES: To review cases of peritonsillar abscess and investigate the initial clinical factors that may influence the duration of hospitalization. To determine the predictive factors of prolonged hospital stay in adult patients with peritonsillar abscess. METHODS: Subjects were adults hospitalized with peritonsillar abscess. We retrospectively reviewed 377 medical records from 1990 to 2013 in a tertiary medical center in southern Taiwan. The association between clinical characteristics and the length of hospital stay was analyzed with independent t-test, univariate linear regression and multiple linear regression analysis. RESULTS: The mean duration of hospitalization was 6.2±6.0 days. With univariate linear regression, a prolonged hospital stay was associated with several variables, including female gender, older ages, nonsmoking status, diabetes mellitus, hypertension, band forms in white blood cell (WBC) counts, and lower hemoglobin levels. With multiple linear regression analysis, four independent predictors of hospital stay were noted: years of age (P<0.001), history of diabetes mellitus (P<0.001), ratio of band form WBC (P<0.001), and hemoglobin levels (P<0.001). CONCLUSION: In adult patients with peritonsillar abscess, older ages, history of diabetes mellitus, band forms in WBC counts and lower hemoglobin levels were independent predictors of longer hospitalization.

This study is to investigate the effect of Icogenin on and its mechanism in anti-metastasis of pancreatic cancer BxPC3 cells in vitro. Using transwell assay, the effects of Icogenin on the invasion of BxPC3 cells were measured. The abilities of cell motility and adhesion in BxPC3 cells were detected by MTT assay and wound healing assay, respectively. The MAPK signal pathway protein expressions were analyzed with Western blotting. Also, the activity of MMP2 was observed by zymography assay. Icogenin inhibited the abilities of motility, adhesion and invasion of pancreatic cancer BxPC3 cells in vitro (P < 0.05), in a dose-depended manner, and inhibited the secretion of MMP2 and phosphorylation of ERK. PD98059 and U0126 which were ERK inhibitors could suppress the abilities of invasion and metastasis of pancreatic cancer BxPC3 cells. It is concluded that Icogenin can inhibit the abilities of invasion and metastasis of pancreatic cancer in vitro by inhibiting the secretion of MMP2 and phosphorylation of ERK.

OBJECTIVETo explore the relationship between imatinib resistance and genes MDR1 and KIT in gastrointestinal stromal tumor (GIST) cells.

METHODSThe MDR1 and KIT mRNA level in GIST882-R and GIST882-S cells were detected by RT-PCR. Immunocytochemistry and Western blot were employed to detect P-gp and CD117 expression in GIST882-R and GIST882-S cells.

RESULTSThe relative expression of MDR1 mRNA was 0.321 + or - 0.033 in GIST882-R and 0.157 + or - 0.056 in GIST882-S cells, and the difference was statistically significant (P<0.05). The relative expression of KIT mRNA was 0.389 + or - 0.063 in GIST882-R and 0.339 + or - 0.067 in GIST882-S, and the difference was not statistically significant (P>0.05). The relative density of P-gp was 0.443 + or - 0.058 in GIST882-R and 0.237 + or - 0.094 in GIST882-S, and the difference was statistically significant (P<0.05). The relative density of CD117 was 0.744 + or - 0.123 in GIST882-R and 0.704 + or - 0.094 in GIST882-S, and the difference was not statistically significant (P>0.05).

CONCLUSIONSOver-expression of gene MDR1 may be associated with imatinib resistance in GIST. KIT may not be involved in imatinib resistance.

OBJECTIVETo investigate the outcome of surgical reconstruction of the tongue after hemiglossectomy with reinnervated rectus abdominis musculoperitoneal flaps in the treatment of tongue cancer.

METHODSFive patients underwent immediate reconstruction of the tongue and oral floor defects with rectus abdominis musculoperitoneal flaps after resection of squamous cell carcinoma of tongue. The rectus abdominis musculoperitoneal flap consists of the rectus muscle, posterior rectus sheath, peritoneum, the 10 th, 11th, 12th intercostal nerves and the vascular pedicle that includes the deep inferior epigastric artery and veins. During the operation a reinnervated rectus abdominis musculoperitoneal free flap, in which the intercostal nerves were anastomosed to the descending branch of hypoglossal nerve, was grafted to remaining tongue stump.

RESULTSAll patients recovered uneventfully from surgery, with no immediate postoperative complications. All transplanted flaps survived. The peritoneum was replaced by squamous epithelium 8 weeks after surgery. The average follow-up period was 10 months. During the follow-up period the contour of the reconstructed tongues was satisfactory. The patients demonstrated good functional mobility of the reconstructed and remaining tongue. The swallowing and speech function was nearly at normal levels and the patients could ingest a solid or semisolid diet.

CONCLUSIONSReconstruction of the tongue with rectus abdominis musculoperitoneal flaps after hemiglossectomy is a suitable, cosmetically acceptable method. Long-term follow-up is needed for reaching some final conclusions.
