Objective:To evaluate the therapeutical effects of diplopore puncture of tympanum and intratympanic administration(DPTIA) on patients with acute secretory otitis media(ASOM).Method:One hundred and forty -one cases with ASOM were divided into two groups randomly,with 69 cases(80 ears) in group A(experimental group) and 72 cases(84 ears) in group B(control group).Group A was treated with DPTIA combined with medication, group B was treated with haplopore puncture of tympanum combined with medication. All patients accepted 1 to 3 courses of treament,and were observed during the period of treatment and 3 months after treatment.Result:The factors (including gender, age, side of ailing ear, course of disease, air-bone gap in the pure tone average,and acoustic immitance type in ailing ear) which may impact the prognosis were matched in two groups prior treatment(P＞0.05). While there was a significant difference in the cure rate and the total effective rate respectively between two groups after treatment(P＜0.05).No adverse reaction or complication was seen.Conclusion:DPTIA is a safe, reliable and effective way to manage patients with ASOM.

BACKGROUND:Titanium mesh has good clinical effect in repairing skul defects, but due to the lack of bone induction ability, the titanium mesh has a poor integration with the bone tissue. OBJECTIVE:To observe the biological properties of the gradient bioactive coating materials on the titanium surface in the skul repair. METHODS: Osteoblasts were co-cultured with the titanium mesh with or without gradient bioactive coatings for 14 days, and then cel proliferation was detected using MTT method. Seventy-one patients with skul defects were enroled, including 43 males and 28 females, aged 15-60 years, and were subjected to skul repair using the titanium mesh with (observation group, n=3) or without (control group, n=38) gradient bioactive coatings. During the postoperative folow-up of 12 months, the repairing effects and adverse reactions were observed in the two groups. RESULTS AND CONCLUSION:(1)In vitrocel culture: the cel proliferative ability was increased significantly in the observation group as compared with the control group at 8, 10, 12 and 14 days after cel culture. (2)In vivo repair: the hospital stay and wound healing time in the observation group were significantly lower than those in the control group (P< 0.05), and at the final folow-up, the postoperative recovery effect was significantly higher in the observation group than the control group (P < 0.05). The titanium meshes were fixed firmly in the two groups, with no floating, infection and exposure. These results show that the titanium mesh with gradient bioactive coating has good biocompatibility and osteoinduction capacity.

OBJECTIVETo explore the relationship between interleukin-6 (IL-6) production and central nervous injury in septic patients.

METHODSTwenty-two septic patients without central nervous system diseases were examined for serum IL-6 and neuron-specific enolase (NSE) levels, and the serum NSE levels and APACHEII scores were compared between patients with low, moderate, and high serum IL-6 levels. The correlations between NSE, APACHEII and serum IL-6 were analyzed.

RESULTSIn patients with low, moderate, and high serum IL-6 levels, the serum levels of NSE were 10.29∓4.05, 16.06∓5.84 and 23.97∓3.28 µg/L, respectively, showing a significant difference between the 3 groups (P<0.001). The APACHEII scores also differed significantly between the 3 groups (14.17∓4.67, 16.40∓4.84, and 24.00∓6.26, respectively, P=0.009). Correlation analysis showed significant positive correlations of IL-6 with NSE (r=0.788, P<0.001) and with APACHEII scores (r=0.733, P<0.001).

CONCLUSIONIn septic patients, serum IL-6 level is significantly correlated with the severity of sepsis and brain injury, and can be used as a marker to monitor brain injury in septic patients.

OBJECTIVE: To sum up the experiences of diagnosis, treatment and medical evaluation of head and neck tumors in aircrew. METHOD: Sixty-seven cases of pilot patients with head and neck tumors in our hospital since September in 1979 to July in 2009 were retrospective analyzed in the study. RESULT: Among 44 aircrew with benign head and neck tumors there were 37 cases continued their flying jobs and 7 cases were permanently grounded; whereas in 23 aircrew with malignant tumors there were 6 cases qualified for flight and 17 patients unqualified. CONCLUSION Benign or malignant of the head and neck neoplasm in the pilots are not the exclusive basis for their medical assessment. Tumor nature, location, efficacy of treatment and the impact on the function of their body should be considered as making the flight medical evaluation for the aircrew with head and neck tumors. Early diagnosis and treatment of head and neck tumors in aircrew are very important for reducing the rate of grounded.
