Objective To establish and evaluate a diagnostic technique based on the AllGlo~(TM) probe for the invasive aspergillosis. Methods With the self-designed AllGlo~(TM) probes and primers and the standards, two standard curves of the real-time PCR based on AllGlo~(TM) probes were established respectively for A. flaws and A. fumigatus,then its specificity, sensitivity and reproducibility were evaluated respectively. Results The findings indicated that the standard curve of A. flavus was Y = - 3. 003X + 36. 825, and A. fumigatus' was Y = - 3. 052X + 38.016, and their interassay coefficient of variation respectively were 15.60% and 12. 94% , suggesting a good reproducibility. The lowest spore concentration they could be detected was 10 CFU/ml, which equated to 100-1000 copies of internal transcribed spacer (ITS)2 genes, suggesting a good sensibility. They didn't have cross-positive reaction with other fungus, human genome and bacteria, which indicated a good specificity. Conclusion The diagnostic technique based on the AllGlo?probe for the invasive aspergillosis possessed a good sensitivity, good specificity and deadly accuracy.

Objective To observe the effects of triptolide(TPL) on the anti-oncogene-APC gene of acute lymphoblastic leukemia cell line Jurkat in vitro. Methods The effects of TPL on proliferation Jurkat cells were assayed by using cell culture, MTT. The effects of TPL on APC gene of Jurkat cells were analyzed by nested methylation specific PCR and RT-PCR. The effects of TPL on the proteinum expression of APC gene were detected by Western blotting analysis. Results Following the treatment of TPL, the cell proliferation rate was degraded as the treatment concentration increased and the culture time extended. The effects were dose and time-dependent. The 48 hour IC50 was 19.7 ng/ml. TPL can reverse hypermethylation of APC gene,and induce the expression of the mRNA and the proteinum. Conclusion Low dose TPL could depress the proliferation rate of Jurkat. The possible mechanism might be its reversing the hypermethylation of APC gene and activiting the expression of APC gene.

The cultivation of research ability can promote eight-year medical students to explore the uncharted academic fields and solve complex clinical problems. One of the firts pilot universities to provide eight-year programs, Xiangya Medical College of Central South University builds on its profound experience in medical education, and establishes a curriculum structure aiming at improving the students' research ability. In the general education stage, cross-disciplinary courses are set up. In the core medical education stage, basic medical innovation experiment extracurricular research courses are set up, and a two-year overseas exchange program is set up in the postgraduate training stage. Different evaluation methods are also designed to meet the specific needs in each stage. This program has achieved preliminary effects.

Objective:To explore the effect of getting out of bed activity 6 hours after silicone breast augmentation surgery on the comfort of patients.Methods:From May 2019 to August 2020, 84 female patients aged 20-37 (28.34±6.27) years who underwent silicone breast augmentation surgery at the Department of Plastic Surgery and Cosmetology at the Second People′s Hospital of Guangdong Province were randomly divided into a control group and an observation group, with 42 patients in each group, using a random number table method. The control group got out of bed 24 hours after surgery, while the observation group got out of bed 6 hours after surgery. The chest drainage and fixation patency, comfort, silicone prosthesis displacement, and incision bleeding rate between the two groups of patients were compared 24 hours after surgery.Results:The extraction time of the thoracic drainage tube in the observation group was (82.64±11.78 hours), which was shorter than that in the control group (90.67±12.44 hours), and the difference was statistically significant ( t=5.369, P<0.01). The comfort scores of the observation group patients at 6 hours after surgery (95.07±4.14) and 24 hours after surgery (97.52±4.07) were higher than those of the control group at 6 hours (91.14±4.03) and 24 hours (94.19±3.93), and the difference was statistically significant ( t=4.413, 3.832, both P<0.01); 7 days after surgery, there were 2 cases of silicone prosthesis displacement in the observation group, with an incidence rate of 4.76% (2/42); there were 2 cases of silicone prosthesis displacement in the control group, with an incidence rate of 4.76% (2/42); there were 6 cases of incision bleeding, with an incidence rate of 14.29% (6/42); there were 5 cases of incision bleeding in the control group, with an incidence rate of 11.90% (5/42). There was no statistically significant difference in the incidence of silicone implant displacement and incision bleeding between the two groups (χ 2=0.21, 0.10, P>0.05). Conclusions:Getting out of bed and moving around 6 hours after silicone breast augmentation surgery can help improve the patient′s physical comfort, ensure smooth fixation of the chest drainage tube, and do not increase the occurrence of incision bleeding in patients.

Objective:To explore the clinical characteristics, diagnosis, treatment and prognosis of patients with POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes).Methods:The main clinical manifestations, auxiliary examination results, diagnosis and treatment process, and follow-up data of 5 patients with POEMS syndrome in Fujian Medical University Union Hospital from April 2017 to November 2018 were retrospectively analyzed, and the features of diagnosis and treatment were discussed with review of literature.Results:The patients with POEMS syndrome had typical manifestations of polyneuropathy (5 cases), organomegaly (4 cases), increased extravascular volume load (4 cases), endocrine changes (5 cases), etc. The patients were also accompanied by clinical manifestations of skin changes (2 cases), bone damage (3 cases), kidney damage (2 cases), anemia (4 cases), etc. Three cases were misdiagnosed as chronic Guillain-Barré syndrome. Five patients were followed up regularly, with a median follow-up time of 16 months (13-33 months). Until the end of follow-up, 1 patient who received DVD regimen chemotherapy had a disease-free survival time of 22 months and a survival time of 24 months; 1 patient underwent autologous hematopoietic stem cell transplantation after receiving pretreatment of melphalan scheme, and the survival time was 6 months; the remaining 3 patients were in the disease-free survival period, and among which 1 patient survived 9 months without disease after autologous hematopoietic stem cell transplantation, 1 patient survived 16 months without disease, and 1 patient survived 18 months without disease.Conclusions:The onset of POEMS syndrome is insidious, its clinical manifestations are complex, and it is easy to be misdiagnosed or missed. Clinicians should strengthen their understanding of this disease.
