Objective:To investigate the stability of flurbiprofen axetil lipid microspheres injection combined with 0. 9% sodium chloride injection or 5% dextrose injection, and provide theoretical basis for the clinical application. Methods:The content changes of flurbiprofen axetil in the mixture of flurbiprofen axetil lipid microspheres injection and 0. 9% sodium chloride injection or 5% dextrose injection were determined in 5 h at 25℃ away from light, and the changes in the appearance and particle size of flurbiprofen axetil lip-id microspheres were investigated. The changes in the appearance and particle size of flurbiprofen axetil lipid microspheres in the mix-ture of flurbiprofen axetil lipid microspheres injection and 0. 9% sodium chloride injection before and after freezing and thawing were also investigated. Results:The appearance, particle size and content had no significant changes in all mixtures in 5 h at 25 ℃ away from light. The appearance and particle size of flurbiprofen axetil lipid microspheres in the mixture before and after freezing and thawing had no significant changes as well. Conclusion:The mixture of flurbiprofen axetil lipid microspheres injection and 0. 9% sodium chlo-ride injection or 5% dextrose injection is stable in 5 h away from light.

Objective By using lung sound spectrum analysis, the clinical efficacy of asthma -relieving manipulation, which is a gentle massage therapy mainly on the acupoints, on acute exacerbation of children asthma was evaluated. Methods We collected the lung sound of 11 children with acute asthmatic attack before and after asthma-relieving manipulation, and then input to the computer for obtaining lung sound spectrum signal data. The sound intensity, average respiratory muscle strength ( RMS) power, total RMS power and the volume of every 25 Hz frequency spectrum were extracted for comparison. Results After asthma-relieving manipulation, the sound intensity, average RMS power, and total RMS power of the children with acute asthmatic attack were significantly lower than those before the manipulation (P<0.01). The results of lung sound spectrum analysis displayed that lung sound volume was significantly lower at frequency band 0~300 Hz after manipulation ( P<0.05 compared with that before the manipulation) . The difference of the lung sound volume was insignificant over frequency band 300 Hz before and after treatment ( P>0.05). Conclusion Lung sound spectrum analysis can be applied to monitor lung function of asthmatic children objectively and quantitatively, and it is a new sensitive method for clinical detection. Asthma-relieving manipulation shows certain effect on acute exacerbation of children asthma.

Clinical studies have confirmed that cryoablation is a safe and effective treatment for lung cancer. Cryoablation has been clinically used in the treatment of various types of lung cancer,and has achieved good therapeutic effects. Some of the complications of cryoablation can be alleviated after symptomatic treat-ment. However,cryoablation still needs further research and exploration in clinical applications.

Objective To estimate the mean annual expenditure of patients with prevalent liver cancer in China on the perspective of the natural progression of the disease and to provide baseline information for liver cancer?related disease burden estimation and evaluation of prevention strategies. Methods A multicenter survey on liver cancer was conducted between 2012 and 2014 in 13 sites where the cancer screening program was conducted in Urban China, by face?to?face interviews with hospitalized patients. Data on basic information, clinical diagnosis and treatment, direct medical expenditure, and direct non?medical expenditure were collected. By?year expenditure and number of visits from the first visit to the end of the survey were analyzed. The trend for the two indicators in each year was analyzed. The subgroup analysis of factors such as sex and age was conducted. All the expenditure data were discounted to the year 2014 and presented in Chinese yuan. The statistical analysis was performed using the SAS 9.4 software. Results A total of 2 222 patients with liver cancer, with a mean age of 55.7±11.2 years, were included. Men accounted for 79.2% (1 759 cases) of the patients, women accounted for 20.8% (463 cases) of the patients, and 75.6% (1 679 cases) of the cases were from cancer hospitals. Stage Ⅰ cases only accounted for 14.1% (299 cases) of all the cases, and most cases were stageⅢorⅣ(62.6%, 1 325 cases). Of the cases, 64.4% (1 430 cases) had pathological information, and 83.6%(1 195 cases) were pathologically hepatocellular carcinoma. The sample sizes for the first 3 years from the first visit were 2 222, 149, and 57, respectively (by?year sample sizes thereafter were<50). The annual total medical expenditures for the first 3 years were 49 091 yuan (95% confidence interval [CI]: 47 376-50 806), 30 506 yuan (95% CI: 26 462-34 549), and 32 100 yuan (95% CI: 25 917-38 283) (P<0.001). The corresponding number of visits were 1.9, 1.6, and 1.5 (P<0.001). The trend for each province was consistent with the overall trend, while the down trend from years 1 to 2 varied among provinces, ranging from 1.4 (Zhejiang province) to 5.6 times (Henan province). For the trend in the first 3 years, differences were found in subgroups such as region (P<0.001) and treatment (P<0.05), instead of sex, age, stage, and other subgroups. Conclusions For liver cancer patients in China, the annual expenditure for the first year in the whole disease course was 1.6 times higher than that for the second year, which varied among provinces. However, information on annual expenditure for the later course of liver cancer is still limited.

OBJECTIVETo evaluate the long-term protection efficacy of neonatal hepatitis B vaccination on chronic hepatitis B (CHB) and liver fibrosis and cirrhosis in adults.

METHODSFrom January to October, 2013, a cross-sectional study was conducted among the participants from Qidong Hepatitis B Intervention Study (QHBIS), who were selected through stratified random sampling. The detections of serum alanine aminotransferase (ALT), HBsAg, anti-HBs, anti-HBc, HBeAg, and anti-HBe were conducted and ultrasonography on liver, gallbladder and spleen was performed for them. The positive rates of each serologic markers, the prevalence of active CHB and liver fibrosis and cirrhosis were calculated, the gender specific differences between vaccination group and control group were compared with Chi-square test.

RESULTSA total of 4 421 participants aged (25.59±1.84) years in vaccination group and 3 880 participants aged (26.61±2.24) years in control group were surveyed. The positive rates of HBsAg, anti-HBs, anti-HBc, HBeAg and anti-HBe were 2.38%, 37.73%, 3.78%, 0.57% and 2.15% in vaccination group, and 9.02%, 29.41%, 16.83%, 2.73% and 8.87% in control group, respectively, the differences between two groups were statistically significant (all P<0.05). The prevalence of active CHB and liver fibrosis and cirrhosis were 0.45% and 0.16% in vaccination group, 1.29% and 0.39% in control group, the differences between two groups were statistically significant (P<0.05). The active CHB prevalence was lower in females than in males in both vaccination group and control group (P<0.05). The liver fibrosis and cirrhosis prevalence was lower in females than in males in control group (P<0.05); whereas, no statistical significant difference in liver fibrosis & cirrhosis prevalence between males and females was found in vaccination group (P>0.05).

CONCLUSIONSProtection conferred by neonatal hepatitis B vaccination could last to marrying age. The gender specific difference in protection efficacy needs further study.
