Objective To explore the clinical efficacy of intranasal endoscopic turbinate fracture relocation press in treatment of chronic hypertrophic rhinitis.Methods According to digital table,66 patients with chronic hypertrophic rhinitis were randomly divided into two groups.33 cases in the observation group were treated with endoscopic sinus lateral fracture crush,33 patients in the control group received inferior turbinate submucosal injection of sclerosing treatment.The clinical effect was compared between the two groups.Results The total effective rate of the observation group was 93.9％,which was significantly higher than 72.7％ of the control group (x2 =6.23,P ＜0.05).The average nasal recovery time was (35 ± 12)d in the observation group,which was significantly shorter than (64 ± 21) d in the control group (t =1.74,P ＜ 0.05).The SCT test results had statistically significant differences between the two groups before treatment and 3 months after treatment (t =3.21,2.85,all P ＜0.05).After treatment,the difference was statistically significant between the two groups (t =2.13,P ＜ 0.05).Conclusion Endoscopic turbinate fracture relocation squeezing surgery in the treatment of chronic hypertrophic rhinitis was satisfied.

Objective To explore the fraction risk in patients with osteoporosis and effects of antiosteoporosis therapy on fracture healing.Methods All the recruited subjects were senile patients with fracture in lower extremity and were treated in the Department of Orthopaedics in Shandong Qianfoshan Hospital from Aug.2006 to Feb.2011.In the total 15 cases,10 were female and 5 were male,aged from 53 to 65 years (average 56.7 years old).After surgical reduction and internal fixation,all the 15 patients did free-weight and continous passive motion (CPM) functional exercise and received anti-osteoporosis treatment.X-ray was taken to show the preoperative and postoperative lumbar vertebrae and fracture position.Meanwhile,bone mineral density and blood calcium level and phosphate level were measured.Results Thirteen out of 15 patients were healed for bone fracture after a 3-month treatment,meeting the clinical standards of the fracture healing.The clinical fracture healing rate was 86.67％.Blood calcium level,phosphate level and the bone mineral density were significantly different between that before and after the treatment ( P ＜ 0.05 ).Conclusion Osteoporosis not only increases the risk of fracture,but also has an adverse effect on the bone healing.Anti-osteoporosis therapy has a positive role to the fracture healing in the senile patients with osteoporosis.

Hemorrhagictransformation(HT)referstointracerebralhemorrhageoccurredwhenthe blood vessels restore blood flow after acute ischemic stroke. It is one of the common complications of ischemic stroke. HT may not have any clinical manifestations and can also be manifested as limb paralysis aggravation, decreased consciousness level, and other symptoms. The symptomatic HT may result in prolonged hospitalization, increased disability and fatality. Therefore, research on the mechanisms and risk factors for HT may be expected to provide the basis for clinical treatment, and thus improve the prognosis of patients. This article review s the formation mechanism of HT, risk factors, screening of high-risk patients, and prevention and treatment.

Although globally recommended standardized stratification treatment of acute myeloid leukemia (AML) effectively improves its therapeutic effects and prognosis,due to unknown personalized differences of tumorous biology,most of the patients eventually develop to therapy failure,relapse,and even death.Additionally,a number of patients are naturally resistant to current used combined chemotherapy and with extremely poor prognosis,This review presents definitions of refractory and relapsed AML,then describes their pathogenetic mechanism and lastly summarizes three aspects of therapeutic principle,clinical drugs and hematopoietic stem cell transplantation (HSCT).To review advances in relapsed and refractory AML diagnosis and treatment will be helpful to master disease characteristics and to guide clinical treatment.

Acute myeloid leukemia (AML) is a group of heterogeneous diseases with diverse genetic abnormalities,variable responsiveness to therapy and prognosis.In recent years,a lot of information has become available regarding chromosome and gene mutations that occur in AML and their influence on prognosis.Improvements in the understanding of molecular biology of AML are critical for accurate diagnosis.risk stratification,monitoring of minimal residual disease and provides opportunities to develop targeted therapies and improve the clinical outcome.This article reviewed chromosome abnormalities and characteristic gene mutations,and discussed their clinical signiflcances and presented new drugs in clinical trials presented in the 55th ASH annual meeting.

Objective To evaluate the safety and efficacy of fiberoptic bronchoscopy in the diagno-sis of 41 neonates with weaning failure.Methods A retrospective study on the results of fiberoptic broncho-scopy was performed in 41 neonates with weaning failure.Results A total of 41 neonates of throat abnor-malities were examined by fiberoptic bronchoscopy,including 38 cases with laryngomalacia,8 cases with seri-ous hyperemia and swelling of the vocal cords,2 cases with scar stenosis of subglottic,and one case in each of congenital laryngeal web,glottic insufficiency and congenital epiglottis cyst;trachea-bronchial abnormali-ties,including 31 cases with tracheomalacia,2 cases with tracheal stenosis,4 cases with partial bronchial ste-nosis,1 cases with bridging bronchus and 1 cases with tracheoesophageal fistula.Thirty-eight neonates under-went fiberoptic bronchoscopy to obtain bronchoalveolar lavage fluid and culture,bacterial culture positive in 15 cases(39.4%),of which 5 cases of Klebsiella pneumoniae,3 cases in each of Pseudomonas aeruginosa and Acinetobacter baumannii,2 cases of Staphylococcus aureus,1 case in each of Escherichia coli and Strep-tococcus mitis;fungal culture positive for 6 cases(15.7%),of which 3 cases of Aspergillus fumigatus,1 case in each of Candida glabrata,Candida albicans and Candida parapsilosis.The most common complications of fiberoptic bronchoscopy were hypoxia and heart rate transient decline(26 cases,63.4%),3 cases fever af-ter operation.Conclusion Fiberoptic bronchoscopy can not only find congenital tracheal deformity and tra-cheal mucosa lesions,but also complete the etiology from deep discharge.Fiberbronchoscopy is safe and relia-ble given adequate preparation and if it is performed by skilled personnel.

Objective To observe the effect of restrictive transfusion in colon cancer surgery in elderly patients on postoperative VAP (ventilator-associated pneumonia). Methods Forty cases of elderly patients with colon cancer intending to undertake surgery were randomly divided into restrictive transfusion group (group R) and standard transfusion group (group S) with 20 cases in each group. In group R, patients were administered one third of accumulative fluid loss in the first 60 minute, then the infusion rate were 4 mL/(kg·h) and central venous pressure was maintained at 5 ~ 7 cmH2O. In group S, rate of fluid administration = CVE + deficit +maintenance + loss + third space. Blood gas index including lactic acid and volumes of fluid administered, blood loss, urine volume and thoracic fluid count (TFC) were recorded in the operation. Clinical pulmonary infection score(CPIS) was recorded respectively before operation, 1 day, 3 day, 7 day after operation to evaluate the risk of VAP. Results Compare with those in group S, there were significantly less TFC and intraoperative volumes of fluid administration in group R. The CPIS was significant lower at day1, day3, day7 after operation in group R. There was no significant difference in MAP, HR, CO and urine volume between two groups. Conclusions In colon cancer surgery for elderly patients, restrictive transfusion can maintain hemodynamic stability, ensure the tissue oxygenation, reduce conjunction edema, shorten the recovery and hospital stay and reduce the incidence of VAP.

Objective To determine the effects of Hyperoside ( Hyp) on the memory impairment induced by hypobaric hypoxia. Meth-ods SD rats were exposed in hypobaric hypoxia chamber which simulated 6 100 m high altitude for 7 days to induce memory impairment. Morris maze was applied to determine the effects of Hyp on memory in hypobaric chamber. The activities of SOD and CAT and levels of GSH and MDA in rat hippocampus were measured by assay kit ( Nanjing Jiancheng Bioengineering Institute) . Results In target quadrant,the time and path and the frequency to cross platform were reduced under hypobaric hypoxia as compared with normoxia group ( P < 0. 05 or P<0. 01). Administration of Hyp significantly attenuated the hypoxia-induced the memory impairment responses(P<0. 05 or P<0. 01). The activities of SOD and CAT in rats hippocampus exposed to hypobaric hypoxia were significantly improved in the presence of Hyp as com-pared with the absence of Hyp(P<0. 05 or P<0. 01),so did GSH level (P<0. 05 or P<0. 01). Significant decrease of MDA levels was observed in the hippocampus on exposure to hypobaric hypoxia with Hyp as compared without Hyp. Conclusion Hyp reduces hypoxia-in-duced oxidative stress injury by upregulating activity of antioxidant proteins such as SOD,CAT in hippocampus of rats, which contribute to at-tenuate memory impairment induced by hypobaric hypoxia.
