A comparative study between the indirect immunofluorescent antibody test and anaerobic culture in the study of Bacteroides fragilis, Bacteroides melani-nogenicus, and Fusobacterium nucleatum in 374 clinical specimens was carried out. The data concerning the quality control of the two tests including the rate of correlation, the difference of the sensitivity and specificity,the predictive values, and the time of antiserum preservation were analyzed. It was found that immunofluorescent antibody test had a higher rate of detection than anaerobic culture. It can be cartain that if immunofluorescent antibody test is negtive, it is more likely that the anaerobic bacteria are abscent. The rate of correlation between the two tests was 88.5~95.99%. In addition, immunofluorescent antibody test can be used to verify the quality of anaerobic culture. It was found that our routine culture for B, fragilis was inperfect and waited for improvement.

This article is to report 4 cases of brain abscess of mixed anaerobic and aerobic infection.Six strains of anaerobic bacteria were discovered, and they included 2 strains of other Bacteroides, 2 strains of Peptostreptococcus, 1 strain of Bacteroides melaninogenicus and 1 strain of Bacteroides fragilis. Four strains of aerobic bacteria including 2 strains of Proteus vulgaris, one strain of Hemophilus influenzae and one strain of Acinetobacter calcaaceticus var. Iwoffi were also discovered.Brain abscess due to anaerobic organisms was compared with three cases of brain abscess due to Staphylococcus aureus. The former usually was more chronic and presented a solitary abscess while the latter was more acute in course and presented multiple abscesses with multilocular construction.The only method to differentiate these two kinds of brain abscess is to reveal the anaerobic organisms with anaerobic culture. Surgical drainage and resection of the abscess cavity if possible combined with proper antibacterial drugs can yield good results.

Objective To compare the outcome between McKeown minimally invasive approach and left chest-neck incision approach esophagectomy in mid-to-distal esophageal cancer.Methods The clinical data of 148 patients with mid-to-distal esophageal cancer from January 2009 to October 2013 were analyzed retrospectively.Seventy-eight patients (observation group) were performed with McKeown minimally invasive approach esophagectomy and 70 patients (control group) were performed with left chest-neck incision approach esophagectomy.The peroperative period status,postoperative complications and lymph nodes transfer between two groups were compared.Results All the operations were performed successfully.One patient in control group was dead because of acute myocardial infarction.The blood loss in observation group was significantly lower than that in control group[(89.2 ± 40.7) ml vs.(361.6 ± 81.5) ml] (P ＜ 0.05),the number of lymph nodes harvested and lymph node of thorax were significantly higher than those in control group[(22.8 ± 5.6) lymph nodes vs.(15.7 ± 3.4) lymph nodes,(14.7 ± 4.6) lymph nodes vs.(9.1 ± 3.6)lymph nodes] (P ＜ 0.05),the hospital stay was significantly shorter than that in control group [(11.6 ± 3.5)d vs.(14.0 ±6.6) d] (P ＜0.05).There were significant differences between two groups with regard to pneumonia,atelectasis,pleural effusion and delayed gastric emptying [5.1％ (4/78) vs.12.9％ (9/70),3.8％ (3/78) vs.11.4％(8/70),2.6％(2/78) vs.10.0％(7/70),9.0％(7/78) vs.1.4％(1/70)] (P ＜0.05).The transfer rate at the side of right recurrent laryngeal,left recurrent laryngeal and upper mediastinal lymph node in observation group were significantly higher than those in control group(P ＜ 0.05).Conclusion McKeown minimally invasive approach esophagectomy is feasible and safe which has lower blood loss,lower respiratory complication,shorter hospital stay and more number of lymph nodes harvested.

Objective To analyze effects comparison of thoracoscopy combined with laparoscopy surgery and the conventional thoracotomy in treatment of esophageal cancer.Methods 88 patients with esophageal carcinoma in the past two years in our department were randomly divided into the two groups according to the digital form,each group had 44 cases.The control group was given radical operation as the treatment for esophageal carcinoma,while the observation group used thoracoscope combined with laparoscope radical operation for treatment.The clinical efficacy of the two groups was compared.Results The operation time of the observation group was slightly higher than that of the control group (t =1.372,P ＞ 0.05),the number of lymph node dissection in the observation group was more than that of the control group (t =1.573,P ＞ 0.05).The intraoperative blood loss [(85.6 ± 30.7) mL],postoperative extubation time [(4.1 ± 1.3) d],chest drainage volume [(550.0 ± 30.5) mL] and postoperative hospital stay [(10.8 ± 2.2)d] in the observation group were significantly lower than those in the control group [(220.4 ± 58.7)mL,(7.5 ±1.8)d,(1 130.0 ±50.8)mL,(17.1 ±3.8)d,(t =18.847,6.486,40.649,8.938,all P ＜0.05)].The incidence of postoperative complications in observation group(6.82％)was significantly lower than that of control group (27.27％) (x2 =5.143,P ＜ 0.05).Conclusion Thoracoscope and laparoscope combined surgery in treatment of esophageal carcinoma can shorten time of being in hospital,decrease blood loss,reduce the incidence of complications,receive high safety and remove lymph node more thoroughly.

A total of 226 strains of organisms was isolated from the cultures of the subeschar unburnt tissues of the burn patients admitted to this institute in the period from April 1980 to April 1982. Among the organisms, gram-negative bacilli exceeded gram-positive cocci in number. The frequently seen gram-negative bacilli, in the order of frequency, were Pseudomonas, Serratia, Klebsialla, and E. coli. And the frequently seen gram-positive cocci were Staphylococcus aureus, Staphylococcus albus, Streptococcus fecalis, and Streptococcus hemolyticus.The quantitative culture of the biopsy specimen showed its value in our clinical application. In cases of multiple infections, after the identification and precise count of the bacterial colonies on the cultures were done, the percentage of the various organisms could be obtained and the main pathogen was revealed.It was pointed out that ordinary culture media were only favorable for rapid growth of bacteria but the existence of fungi was usually masked. A. modified method of fungus culture, tissue thread culture, was used for the early diagnosis of fungus infection. 38 specimens were studied simultaneously with three methods. The positive rate for fungus was 8% in ordinary cultures, 26% in his-tologic examinations, and 61% in tissue thread cultures.Anaerobic culture was performed for 102 swab specimens from the burn wounds and a positive rate of 14.7% was obtained. In addition, anaerobic blood culture was performed in 10 cases of severe burns with 2 positive cultures. It is suggested that anaerobic infections should not be neglected in burns.

The aim of this study was to evaluate the seed quality of C.deserticola and establish quality grading rules of seeds by detecting the impacts of different processing methods on the contents of the effective components of C.deserticola for optimizing the suitable processing method.The seed quality was judged by thousand-kernel weight,empty embryo rate and water content.The samples were preliminary processed by freeze-drying,natural drying and hot air circulation drying respectively,and the content of phenylethanoid glycosides was determined by HPLC-UV.The seed quality classification standard of C.deserticola was established,and the seeds were divided into three grades based on the standard.It was found that freeze-drying method was optimum,featuring less effective component loss,beautiful appearance of herbal piece,crisp texture and fast drying.In conclusion,this study laid a foundation for the quality control of the seeds of C.deserticola with the provision of scientific evidence for the initial processing of the fresh product.

An statistical analysis of aorta-septal angle(AS angle) between anterior wall of aorta and ventricular septum was taken,AS angle was measured fromthe right ventricle with long-axis, two-dimensional echocardiongram of the left ventricle in 227 consecutive cases of patients with cardiovascular diseases and 80 healthy adults since 1985. It was found that AS angle for normal adults at the end of systoie(ES) and the end of diastole(ED) being 118.50?? 7.70? and 110.60??8.23?; the difference between ES and ED was 7.89??4.51?. In patients with overburdening of left ventricular volume and resistance of coronary artery disease, car-diomycpathy and hypertension , AS angles were amaller,and in patients with overburdening of right ventricular pressure of rheumatic mitral stenosis, AS angles were larger than healthy adults. The difference between ES and ED was smaller than normal for all patients. It was also found that in patients with heartdisease AS angle tends to be smaller or larger before the appearance of abnormality of the left ventricular cavity. Our data suggested that AS angle variance might afford some clinical significance of diagnosis

Objective To investigate the difference of size-specific dose estimates ( SSDEs ) based on effective diameter ( def ) and water equivalent diameter ( dw ) in coronary computed tomography angiography ( CCTA) and explore the causes. Methods A total of 99 patients undergoing CCTA were enrolled in this retrospective study. SSDEs ( SSDEd ef and SSDEdw ) were calculated in two approaches using def and dw , respectively. Mean absolute relative difference ( MARD) was computed as an index to quantify the consistency of SSDEd ef and SSDEdw . Multivariate stepwise regression analysis was performed to study the factors influencing MARD. Results The values def and dw were positively correlated with body mass index (BMI) (r=0. 869, 0. 823, P<0. 05). The median (interquartile range) of SSDEdef and SSDEdw were 12. 34 ( 11. 75, 12. 98) mGy, 13. 78 ( 13. 02, 15. 04) mGy, respectively. SSDEdef was lower by 10. 45％ than SSDEdw( Z=-8. 186, P<0. 05) . Both SSDEdef and SSDEdw were negatively correlated with BMI and dw(r=-0. 765, -0. 680, -0. 701, -0. 840, P<0. 05). MARD of SSDEdef and SSDEdw was generally at 11. 39％. No statistical significance was found in the correlation of MARD with BMI ( r=0. 031, P>0. 05) , however, positive correlation was shown between MARD and def ( r=0. 251, P<0. 05) , but negative correlation for MARD and dw(r=-0. 379, P<0. 05). With respect to the factors influencing MARD, four variables were included into the regression equation. MARD was positively correlated with the area of both air-filled lungs ( Arealow ) and soft tissues ( Areasoft ) (β=0. 634, 0. 102, P<0. 05) , and negatively correlated with the area of bone, enhanced cardiac chambers and aorta ( Areahigh ) and the CT value of air-filled lungs ( SIlow ) (β=-0. 234,-0. 343, P<0. 05) . Conclusions SSDEdef was approximately 10. 45％ lower than SSDEdw , which was predominantly influenced by the area of air-filled lungs due to the characteristics of low X-ray attenuation in CCTA.
