Isolation and identification of human influenza virus from a stale respiratory tract specimen with human airway epithelial cells / 中华微生物学和免疫学杂志

Objective To investigate the possibility of using well-differentiated human airway epithelial cells (HAE) to isolate and identify human influenza A virus from a stale respiratory tract specimen.Methods The stale specimen used in this study was a nasopharyngeal swab specimen collected from a patient with unexplained pneumonia in Qinghai in 2010.It was positive for influenza A virus (H3N2) RNA, but negative for hemagglutination.Equal amount of the specimen was inoculated on HAE and on Madin-Darby canine kidney (MDCK) cells for virus isolation and passage.Cytopathic effects were observed daily after inoculation.Hemagglutination inhibition test was performed at every passage.Electron microscope was used to observe viral morphology.Viral genome was sequenced, followed by molecular evolutionary analysis.Results No progeny virus was isolated in MDCK cells, while a influenza A virus subtype H3N2 strain [A/Qinghai/178/2010(H3N2)] was isolated in HAE with a typical morphology and cytopathic effect of influenza A infection.The hemagglutination inhibition activity was 1∶16.Results of the molecular evolutionary analysis of viral genome showed that the influenza A virus (H3N2) strain was highly homologous to the A/Nanjing/1655/2010(H3N2) strain, which was isolated during the 2010 influenza pandemic in Nanjing.Conclusion HAE can be used for isolation and identification of virus from stale respiratory tract specimens.It is more sensitive than MDCK cells with regard to human influenza virus isolation.

Treatment of Chronic Obstructive Pulmonary Disease Based on Syndrome Differentiation / 中华中医药杂志

Chronic obstructive pulmonary disease is a common stubborn respiratory disease(COPD);it belongs to "lung-distension" in Chinese medicine.The author believes that its pathogenesis should be considered from clinical characteristics,in all COPD stages,according to the specific characteristics of the symptoms,listed several therapies:warming lung for dispelling cold,dispersing lung qi and clearing heat,benefiting qi for warming yang,eliminating phlegm and removing blood stasis,so as to improve the symptoms of patients with COPD.The author used Xiaoqinglong decoction,Buzhongyiqi decoction,Buyuan decoction,Gleditsia pills,Juanxiao decoction,Mahuang Xingren Shigao decoction combined with Mengshi Guntan pills,Mahuangfuzixixin decoction combined with Linguizhugan decoction to treat COPD in all phases.For example,the six cases about acute exacerbations and stable period had improved apparently.Treatment is basically to determine root vacuity and tip repletion,intermingled deficiency and excess.

Surgical treatment of stale acetabular fracture through combined approaches / 中华创伤骨科杂志

Objective To summarize the surgical techniques to treat complex stale acetabular fractures through combined approaches. Methods From February 1993 to September 2005, 21 cases (12 males, 9 females, mean age of 33 years old) of complex stale acetabular fracture were treated with open reduction and internal fixation through combined approaches (K- L+ ilio- inguinal). Of the 21 fractures, 3 were transverse and posterior wall ones, 4 T- shaped ones, 11 both column ones, and 3 hemi- transverse and anterior column ones. Results 12 cases (57.1% ) got anatomic reduction, 5 cases satisfactory reduction (23.8% ), but 4 cases unsatisfactory reduction (19.1% ). The rates of anatomic reduction for the early 6 years and for the latest 6 years in this study were 44.4% and 66.7% respectively. 15 cases were followed up for 2 to 12 years. The excellent and good rate for clinical and roentgenographic results were 65.3% and 67.2% respectively. The clinical results for anatomic and non- anatomic reduction groups were 78.6% and 32.8% respectively (P

Research for maintaining stale data based on data warehouse technique / 医疗卫生装备

At present,the main method for data process is to eliminate or save the data,and stale data is seldom reutilized.In this article,the author makes a method that using data warehouse to manage stale data.It can utilize the character of data warehouse to manage stale data and to find the rule in the stale data.

A Comparative Study on the Characteristics of Demographic Data, Clinical Features, and Personality in Hospitalized Male and Female Alcoholics / 신경정신의학

OBJECTIVE: This study was designed to compare the characteristics of demographic data, clinical features, and personality in male and female alcoholics and to identify the clinically meaningful differences in the etiologies and the clinical features between the two groups. METHODS: The study group was composed of 30 males and 21 females who were recruited into the inpatient treatment. The researchers used self-reporting questionnaire composed of demographic data and drinking patterns, Michigan alcoholism screening test(MAST), self-rating anxiety scale(SAS) and self-rating depression scale(SDS) of Zung, Minnesota Multiphasic Personality Inventory(MMPI), symptom Checklist-90-revision(SCL-90-R), and Eysenck personality questionnaire(EPQ) . The differences between the two groups were tested by chi-square test and independent-samples t-test. RESULTS: 1) Education level of female alcoholics was significantly less than that of male alcoholics(p<0.05) and the birth order of female alcoholics was significantly higher than that of male alcoholics(p<0.05). 2) The level of socioeconomic status of female alcoholics was significantly lower than that of male alcoholics(p<0.01). 3) The initial motivations of female alcoholics were mainly due to social, psychological, and intrafamilial problems while those of male alcoholics were due to social problems. There were significant differences between the two groups(p<0.05). 4) The onset of initial drinking in female alcoholics was significantly earlier than that of male alcoholics(p<0.001). 5) The average amount of daily drinking in female alcoholics was significantly less than that of male alcoholics(p<0.01). 6) Withdrawal symptoms, physical disorders, and social or legal problems induced by alcohol drinking in female alcoholics were significantly less than those of male alcoholics(p<0.05) 7) The mean scores of PY scale of SCL90R and of L scale of EPQ in female alcoholics were significantly higher than those of male alcoholics(p<0.05). CONCLUSION: Demographic and psychosocial factors differed to a significant degree between male and female alcoholism. We suggest that these factors are more important in female alcoholism than in male one in the etiologies and the clinical features. These differences are due to more complex factors rather than simple ones, thus the further evaluations are needed to elucidate the differences in the etiologies between male and female alcoholism.
