Objective To investigate the effects of single and combined exposure to ozone and nitrogen dioxide on airway injury and inflammatory levels in mice. Methods Eighty BALB/C mice were randomly divided into eight groups:four were sensitized model groups(the control group,the O3 group,the NO2 group and the O3+NO2 group based on the way of exposure) ,the other four were non-sensitized groups. The concentration of O3 was 0.16 mg/m3,NO2 was 0.30 mg/m3. Mice were exposed 2 hours every day for 7 consecutive days. Mice were sacrificed in the exposure end and cell counting and cytokine measurement from bronchoalveolar lavage fluid(BALF) were performed. Results In the sensitized groups,neutrophil proportion and IL-6 were significantly increased except the control group and IL-2 and MDA were also significantly increased in the O3 group and the O3+NO2 group(P

OBJECTIVE:To provide a reference for clinical use of anti-tumor adjuvant drugs as is reasonable,effective and economical. METHODS:By retrospective investigation and analysis,the utilization of anti-tumor adjuvant drugs in the oncology department of our hospital during 2010 and 2013 was analyzed statistically in respect of the type,dosage form,consumption amount,DDDs,DDC,DUI etc. RESULTS:The anti-tumor adjuvant drugs in our hospital were dominated by injections,especial-ly domestic drugs,the consumption amount of which accounted for 80% of the total consumption amount of anti-tumor adjuvant drugs each year. The anti-tumor adjuvant drugs were mainly used for symptomatic treatment of various adverse reactions. Drug syn-chronization was relatively good each year,however,excessive use of individual drugs existed. CONCLUSIONS:Anti-tumor adju-vant drugs have relatively better synchronism in the drugs quantities and medication number. However,individual drugs have exces-sive use and other irrational use.

Objective To analyze the clinical features of the hospitalized children with laboratory-confirmed influenza in Suzhou. Methods The demographic information, laboratory test results, clinical features, treatments and outcomes of the hospitalized children with laboratoryconfirmed influenza were collected retrospectively. The data were analyzed using chi square test,Cochran-Armitage trend test. Results Four hundred and eighty hospitalized children were diagnosed with laboratory-confirmed influenza during the period of 2005 to 2009. Among these cases, 414 were subtype A and 66 were subtype B. The positive rate was 2.66%. Four hundred and nineteen cases (87.29 %) were ≤ 5 years old. Most of the cases developed during winter (from December to April the next year) and summer (from July to August). The age and sex distribution didn't vary from year to year (x2=9. 7768,x2 = 8. 7573; both P＞0.05). The mean disease course was (16.22± 9.41)days, and the mean hospitalization duration was (7.89 ±2.97) days. The percentages of patients with symptoms of fever, dyspnea and diarrhea or requiring oxygen treatment decreased with age (Z =4. 9430, Z=2. 1021, Z=3. 2073 and Z=2. 3277, respectively; all P＜0.05). The percentages of cases with concomitant pneumonia and upper respiratory infection also decreased with age (Z =-3. 8762 and Z=-3. 5095, respectively; both P＜0.01). Fifteen point five percent (60/387 cases)of the cases were co-infected with pneumococcus and 15. 0% (72/480 cases) were co-infected with respiratory syncytial virus (RSV). The level of C-reactive protein was significantly higher in cases with bacterial co-infection than those with viral co-infection (Z= -3.1290, P ＜ 0. 01 ).Conclusions Hospitalized children with influenza are more common in winter and summer in Shuzhou.Many patients are co-infected with pneumococcus or RSV. The symptoms are more severe in younger children.

Objective To observe the effect of dexmedetomidine in cerebral aneurysm embolization in pa-tients with hypertension. Methods Sixty patients with hypertension undergoing emergency cerebral aneurysm em-bolization were randomly divided into two groups:research group(dexmedetomidine given group) and control group. SBP,DBP,HR,plasma norepinephrine(NE):baseline value(T0),before intubation(T1),after intubation (T2),after extubation(T3). Extubation time and anesthetic-related complications were also recorded. Results The hemodynamic parameters and plasma norepinephrine concentration in the research group were more stable than those in the control group at different time point during perioperative period. There was no difference between two groups about extubation time. The incidence of anesthetic-related complications in research group was lower than control group(P < 0.05). Conclusions Dexmedetomidine can reduce the stress response of intubation ,extuba-tion and perioperative hemodynamic fluctuations in cerebral aneurysm embolization in patients with hypertension. It can also reduce the consumption of prorofol and the incidences of adverse effects.

OBJECTIVE:To observe the changes of heart type fatty binding protein (H-FABP) and brain natriuretic peptide (BNP)when carvedilol and bisoprolol in the treatment of elderly patients with chronic heart failure(CHF). METHODS:110 CHF patients were randomly assigned into carvedilol group and bisoprolol group (n=55). Carvedilol group was given carvedilol 3.125 mg,bid,doubling dose every 2 weeks to reach target dose 25mg or maximum tolerant dose;bisoprolol group was given bisoprolol 1.25 mg,qd,doubling dose every 2 weeks to reach target dose 10 mg or maximum tolerant dose. Treatment course lasted for 6 months. Clinical effective rate of 2 groups were observed after treatment. Echocardiography was used to measure the changes of LVEDD,LVEF,SBP and DBP before and after treatment. The plasma concentration of BNP and H-FABP were measured by radio-immunoassay. RESULTS:After treatment,total effective rate of carvedilol group(96.4%)was higher than that of bisoprolol group (89.2%),with statistical significance(P<0.05). Compared with before treatment,the levels of LVEDD,LVEF,BNP,H-FABP, SBP and DBP in 2 groups were all decreased significantly after treatment,with statistical significance (P<0.01 or P<0.05). CON-CLUSIONS:Both carvedilol and bisoprolol can significantly improve cardiac function,but carvedilol efficacy is more significant. At the same time,significant decrease of H-FABP before and after treatment indicate that H-FABP can be used as a reliable index of heart failure treatment effect.

Objective To compare the clinical diagnostic value of 320 row four-dimensional CT angiography (4D-CTA)and digital subtraction angiography (DSA)in untreated arteriovenous malformation (AVM)patients.Methods Thirty-six patients with AVM diagnosed by DSA were included in this study.Two independent readers blind to the results of all examinations evaluated the find-ings of DSA and 4D-CTA of each patient.All results were then documented using a standardized scoring sheet.Results The diagno-sis results of 4D-CTA for AVM lesions in all 36 patients were accurately consistent with those of DSA,including the position,size and vascular structure.There were 14 cases with the largest diameter <3 cm,20 cases 3-6 cm,2 cases >6 cm.Lesions involved only the anterior circulation in 13 cases,only the posterior circulation in 13 cases,and both the anterior and posterior circulation in 10 cases.Conclusion 4D CTA has excellent diagnostic accuracy in the detection of AVM lesions,including size,location,feeding ar-teries and draining veins,with similar value as DSA in the clinical diagnose and evaluation of AVM.

Objective To observe the anti-inflammatory effects of rhamnocitrin in Oxytropis falcata Bunge;To provide experimental evidence for searching the anti-inflammatory active component of Oxytropis falcata Bunge. Methods Kunming mice or Wistar rats were randomly divided into model group, naproxen group and rhamnocitrin high-, medium-, low-dose groups, and corresponding medicines were administered by gavage for 7 days. Animal inflammatory models were established respectively by the mice ear swelling induced by dimethylbenzene, the mice abdominal capillary permeability induced by acetic acid, the rat paw edema created by injection of albumen and the rat granuloma induced by cotton pellet wool. The effects of rhamnocitrin on acute and chronic inflammatory animal models were observed. Results Different doses of rhamnocitrin groups could reduce the animal ear swelling, abdominal capillary permeability, paw edema and granuloma. Compared with the model group, there were obvious differences in rhamnocitrin groups (P<0.05). High dose rhamnocitrin group and naproxen group showed relatively strong inhibition effects on swelling, with statistical significance (P<0.05). Conclusion Rhamnocitrin has anti-inflammatory effects and is an important biological component of Oxytropis falcata Bunge.
