Objective To study the Inflammation and immune stress of obese asthmatic rats by adipocytokines.Methods Fourty C57BL/6 J mice were randomly divided into control group, obese group, asthma group and obese asthma group.Mice in the control group were fed normal diet and PBS, high-fat diet(75% normal diet, 10% egg yolk powder, lard 10%, 5% sugar)and PBS in obese group, normal diet and OVA(PBS)in asthma group and fat diet and OVA(PBS)in obese asthma group.Detect the leptin, adiponectin, resistin, IL-4, IFN-γ, IL-17 content with ELISA in serum and bronchoalveolar lavage fluid(BALF).Using Pearson correlation to analyze and evaluate these factors' correlation in plasma and BALF.Results The difference of leptin, adiponectin, resistin in plasma and BALF(excepted leptin)between four groups were statistically significant (P<0.05), the leptin levels between plasma and BALF has a positive correlation(R2=0.8215, P<0.05)in obese mice, there was no correlation between plasma and BALF for the adiponectin, resistin.The adiponectin content and IFN-γ levels were also negatively correlated(R2=0.9146, P<0.05)in BALF, while there was no correlation between IL-4,IL-17 and leptin, adiponectin, resistin.Conclusion Adipocytokines has a regulatory function of the immune response in obese asthmatic rats, and participate the inflammatory reaction.

Objective To investigate the effect of cisplatin ototoxicity on apoptosis of spiral ganglion cells(SGC), and relation between signal transportation of Caspase-3 and apoptosis of SGC.Methods Forty guinea pigs were randomly divided into 4 groups, and injected cisplatin (1, 2, 4 day group and control group). ABR and AERP (40 Hz Auditory Event Related Potentials) were tested every day after the injection, to find out the threshold changes of guinea pigs. Apoptosis was detected by terminal deoxynucleotidyl transferase(TdT)-mediated deoxyuridine triphosphate(d-UTP) nick end labeling method (TUNEL), and immunohistochemistry method was used to detect Caspase-3 p20 segment of SCGs.Results It was observed that the more cisplatin injected, the worse hearing guinea pigs got, and the damnification of threshold on 8KHz was significantly higher than that on 1 kHz. At the same time, TUNEL staining and the expression of Caspase-3p20 segment rose up gradually, and significant difference was observed compared with control group ( P

OBJECTIVE:To improve rational drug use and reduce potentially inappropriate medication (PIM). METHODS:PIM of 700 elderly inpatients in internal medicine department of our hospital was evaluated by Beers criteria(2012 edition)and STOPP/START criteria. RESULTS:700 inpatients whose mean ages were (76.3 ± 7.2) years old took (12.1 ± 4.9) kinds of drugs per patient. 144 cases involved PIM(20.6%). The number of PIM was 220 in total,among which there were 117 cases/times relat-ed to drugs and 22 cases/times related to disease in according to Beers criteria,9 cases/times of STOPP and 72 cases/times of START. Drug with most frequency of PIM in accordance with Beers was benzodiazepines and most frequency in STOPP was thia-zides that used by patients with gout histonry. The most omission frequency of START prescription were absence of metformin thera-py for type 2 diabetes and absence of antiplatelet therapy for diabetes complicated with cardiovascular risk. CONCLUSIONS:A high prevalence of PIM in elderly inpatients in our hospital requires various measures to prevent its occurrence.

BACKGROUND: Acellular dermalmatrix (ADM), as a new material, is generally applied to tissue repair after head and neck tumorectomy. However, hypopharyngeal carcinoma surgery always involves in repair and functional reconstruction of defected tissue; therefore, the application effect of ADM needs to be further studied for repairing laryngopharynx defect. OBJECTIVE: To evaluate the clinical effect of ADM in repairing laryngopharynx defect following tumorectomy. DESIGN, TIME AND SETTING: A retrospective case analysis was performed at the Department of Otolaryngology-Head and Neck Surgery, Institute of Battle Surgery, Daping Hospital, the Third Military Medical University of Chinese PLA from May 2005 to June 2006.PATICIPANTS: A total of 25 male cases aged 45-68 years including 22 patients with tumor in the lateral wall of the unilateral piriform fossa and 3 patients with in the posterior wall of laryngopharynxat were finally diagnosed as squamous cell carcinoma. METHODS: According to clinical stages, patients underwent partial or complete laryngopharyngectomy. ADM was used to repair oropharynx mucosa following the laryngopharyngectomy. However, ADM alone was used to repair piece-shaped oropharynx mucosa, limiting by being unable to complete reconstruction of spatial structure. Therefore, myocutaneous flap or other materials combined with ADM was beneficial for reconstruction of laryngopharyngeal cavity following complete laryngopharyngectomy. MAIN OUTCOME MEASURES: The effect of ADM on functional reconstruction of swallowing, breathing, and pronouncing. RESULTS: A total of 25 patients were included in the final analysis. No patients suffered with the pharyngeal fistula. Only one case encountered the subcutaneous infection at day 20 after surgery, but recovering after regular change of dressing and treatment of antibiotics. About 15 patients who accepted the surgery of partial laryngopharyngectomy suffered with bucking, but after 30-60 days, the symptom relieved, even disappeared, in spite of 3 cases still bucking when they swallowed liquid diet. Breathing function was recovered, and tracheal cannula was removed 6-12 months after surgery. Ten of them who accepted total laryngopharyngectomy had resumption of normal oral diet after 20 days. The follow-up periods after the surgery lasted 12-30 months. The allograft became normal mucosa finally, without rejection or scar formation. The follow-up of 10 patients lasted more than 24 months, one case had relapse of tumor, still alive after the second surgery. CONCLUSION: ADM with perfect histocompatibility and easy operability, can be applied to repair deletion of laryngeal or pharyngeal tissue and recover functions of pronouncing, breathing, and swallowing after tumorectomy. The combined use of ADM and musculo-cutaneous flap was effective and satisfactory.
