OBJECTIVETo analyze the fungal composition in Massa Medicata Fermentata based on culture dependent method and independent PCR-SSCP technique.

METHODFungi were directly isolated from Massa Medicata Fermentata samples. The obtained strains were identified according to morphology and DNA sequence. Meanwhile the total fungal DNA was extracted from Massa Medicata Fermentata samples, the cultural independent PCR-SSCP technique based on β-tubulin gene were used to identify the mycobiota.

RESULTAccording to cultural method, Aspergillus flavus and Rhizopus oryzae were present in Massa Medicata Fermentata samples, while A. flavus and A. niger were present in fried Massa Medicata Fermentata samples. In contrast, 5 species were obtained by PCR-SSCP technique, A. flavus was overlapped with fungal taxa derived from culture dependent method; A. ambiguu and A. s ivoriensis were dominant with relative abundance of 57% and 35% respectively, while the relative abundance of A. flavus was as low as 4%. None species was obtained from fried Massa Medicata Fermentata samples.

CONCLUSIONPCR-SSCP based on β-tubulin gene could distinguish fungi into species, culture dependent method combined with culture independent method could better understand the fungal composition associated with Massa Medicata Fermentata fermentation.

Objective To explore the application of repeated measurement‘analysis of variance'(ANOVA)in evaluating the effectiveness of 'community-based hypertension self-management program'.Methods A community-based parallel controlled trial was conducted among 3 communities.169 patients in intervention group took part in the course on hypertension self-management program once a week and 204 patients in control group received routine hypertension management services.Data collected through questionnaire at baseline and 6 months,12 months after intervention and were compared through repeated ANOVA measurement.Results Subjects in the intervention group showed statistical significance and linear trends in health self-evaluation,distress,in lOW spirit,self-efficacy in managing symptoms(SEMS),self-efficacy to managing diseases in general(SEMDG),systolic blood pressure(SBP)and diastolic blood pressure(DBP)over time by univariate test of repeated measurement ANOVA.The score of SEMS increased from 6.84±2.53 at baseline to 8.20±1.44 at 12 months after intervention while SEMDG from 7.28±2.45 to 8.89±1.05,and SBP decreased from 137.66±7.30 inln Hg(1 mm Hg=0.133 kPa)to 130.41±7.71 mm Hg.DBP decreased from 84.13±6.70 mm Hg to 81.04±5.98 mm Hg respectively.Only tow spirit and SBP changed over time were seen in the control group.Self-evaluation,distress,in low spirit,caused by diseases,SEMS,SEMDG and SBP were statistically different between control and intervention groups,and the effect of interaction between groups and time span were statmtically significanton indicators as self-evaluation,low spirit,self-efficacy in managing symptoms,seLf-efficacy tO manage diseases and sBP etc,by multivariate test of repeated measurement ANOVA. Conclusion Repeated measurement ANOVA not only could be used to analyze group-effect,but could also explain the effect and the interaction among groups and time,to make the results more reliable.The self-management approach could improve the health status and self-efficacy of the patients,so as to reduce the blood pressure.Our result showed that it was effective for hypertensive patients to be on the chronic diseases selfmanagement program.

In handling crises in hospitals caused by natural disasters like earthquake, systemati cpractical measures of crisis management are needed, which include: early contact with top managements for support in counter disaster supplies, immediate organization of temporary first aid stations by hospital staff, logistic support by full time personnel to solve problems such as drugs and medical equipments as well as food and drinking water, and psychological consultation to patients and staff members.

Objective To investigate the feasibility and clinical effect of the posterior single segment anterolateral decompression and anterior column reconstruction in the treatment of thoracolumbar burst fractures. Methods A retrospective study was done on 21 patients with type Denis B thorocalumbar burst fractures who were treated by posterior approach minimal incision pedicle SCreW fixation,single segment anterolateral decompression and titanium mesh and bone graft from August 2007 to August 2009.There were 15 males and six males at mean age of 35.6 years(range,23-50 years).The involved segments included T12 in six patients,L1 in 11,L2 in three,and L3 in one.The preoperative spinal canal enemachment rate was 62.5%and the anterior-middle vertebral compression of all patients was less than 50%.CT scanning showed normal vertebral body and inferior endplate structure.The fracture reduction,graft fusion,neurological function recovery,correction loss,lumbar activities and adjacent lumbar disc degeneration were observed through preoperative,immediate postoperative and final follow up X-ray,CT and neurological examinations. Results The operation duration was 1.5-3.2 hours(average 2.1hours),with the bleeding of 350-1 000 ml(average 580 ml).All the patients were followed up for 4-26months(average 10.3 months),which showed that the vertebral fusion time was 4-6 months,with no loss of the vertebral height,implant breakage,loosening or extrusion.The nerve function was improved for 1-2 grades. Conclusions With correct selection of the indications,the posterior single segment anterolateral decompression and anterior column reconstruction is a reliable fixation,for it takes advantages of simple operation,minor trauma,less fusion segments and fast recovery.

The depositions of immunoglobulins on the retina of diabetic rat were studied with immunohistochemistry,immunofluorecence and computer analysing system.In comparison with control group, depositions of IgG,IgA and IgM on the retina of diabetic rat induced by streptozotocin were significantly increased (all P＜0.05 ).So the immunoglobulin depositions may contribute to the pathogenesis of diabetic retinopathy.

Objective To explore the related factors of reoccurence of peritonitis in pateints with continous ambulatory peritoneal dialysis in order to provide ehnical basis for preventing the reoccurence of peritonitis.Methods The eduction degree,primary diseases,ages,Hb,Alb,the possible reason of peritonitis,dialysis time and payment method of medical expenses of 12 cases with peritoneal dialysis-ralted peritonitis for 32 times and operators were retrospectively analyzed.The correlation between the above factors and the occurrence of peritonitis was compared.Results The reoccurrence of peritonitis among pateitns with the peritoneal dialysis-related peritonitis was related with the ages,the education degrees of operators,Hb,Alb,the dialysis time and the primary diseases(P<0.05).Those pateints with advanced ages,lower eduction degrees of patients and operators,poor nutrition situations,primary disease of diabetes mellitus,and dialysis times of 1 to 3 years were prone to suffer peritonitis again.But there Was no relation with the gender and the payment method of medical expenses(P>0.05).The main reasons for reoccurence of peritonitis were non-standard operation,constipation and diarrhea.Conclusions The pateints with advanced ages,lower Alb and Hb,lower education degrees of patients and operators,diabetes mellitus,and dialysis times of 1 to 3 years,especially the family member operators,should be strenghtened the follow-up management and re-training,thereby preventing the reoccurence of peritonitis.
