It is difficult to treat severe burn combined injury caused by high voltage. This paper reports the successful treatment of a patient with large cranial area third degree burn, skull exposure, local skull carbonization combined with cerebrospinal fluid leakage caused by ten thousand volts high voltage current. Vacuum sealing drainage was given to protect the wounds from infection after multiple limited debridement in the early stage. The external of the inactivated skull was cleaned in the later stage. Finally, the bilateral anterolateral thigh flap combined with multiple burr holes was used to repair the wound. There were no severe postoperative complications, and the therapeutic effect was satisfactory.

This paper reports the successful treatment of a patient with third degree burn of extra large cranial area, skull exposure, local skull carbonization combined with cerebrospinal fluid leakage caused by ten thousand volts high voltage current. Vacuum sealing drainage was given to protect the wounds from infection after multiple limited debridement in the early stage. The external plate of the inactivated skull was cleaned in the later stage. Finally, the bilateral anterolateral thigh flap combined with multiple burr holes was used to repair the wound.

Objective:To study the differences of intestinal flora between neonatal rats with intrauterine hypoxia and healthy neonatal rats using high-throughput sequencing technology to determine the effects of intrauterine hypoxia on neonatal intestinal flora.Methods:Intrauterine hypoxia model were established in neonatal rats. On d1 and d7 after birth, intestinal samples were collected from intrauterine hypoxic group and normal control group and assigned into INH1 group (intrauterine hypoxia d1), INH7 group (intrauterine hypoxia d7), NOR1 group (normal control d1) and NOR7 group (normal control d7). 16S rRNA sequencing were conducted using these samples and the differences in the diversity, richness and composition of the flora among the groups were compared.Results:(1) The Alpha diversity of the intestinal flora in the INH1 group was higher than the NOR1 group. Specifically, both sobs and chao indices, representing the richness of the flora, in INH1 group were significantly higher than the NOR1 group (sobs index: 114.5±35.6 vs. 50.5±21.3, chao index: 135.6±38.5 vs. 73.9±28.8)( P<0.05). Compared with the NOR7 group, the mean values of sobs, ace, chao, simpson and shannon indices in the INH7 group showed no significant differences ( P>0.05). (2) At the phylum and genus level, the dominant bacterial groups in the intrauterine hypoxia group on d1 were firmicutes and streptococcus and proteus and escherichia for the normal control group. The difference of intestinal flora between intrauterine hypoxia group and the normal control group on d7 was smaller than the difference between the two groups on d1. Compared with INH1 group, the INH7 group had increased escherichia composition and decreased streptococcus composition. Conclusions:Intrauterine hypoxia changes the initial colonization and later affects the abundance and structural composition of the intestinal flora in newborn rats.

Taking the curriculum "society, the individual & medicine" in university of Ottawa faculty of medicine as an example, the cultivation models for comprehensive quality of medical students in China and Canada was compared. In University of Ottawa faculty of medicine, the curriculum "society, the individual & medicine" is throughout the whole medical education, including three themes of statistics and epidemiology related knowledge, health related issues and professional development. The varied teaching modes are combined with electronic teaching equipment and students' subjectivity in learning is emphasized. Drawing insights from the medical education in Canada, we should focus on promoting early contact and lifelong study of medical humanities curriculum for medical students, enriching the curriculum content, enhancing the curriculum practicality, diversifying the teaching methods, strengthening the teachers' training, improving the assessment system and establishing the long-term mechanism.

Canada is one of the leading countries in the world with a leading position in medical education and high quality of medical education.Based on the Ottawa-Shanghai joint medical school collaborative program,this article introduces and analyzes the curriculum system of University of Ottawa School of Medicine.The curriculum is designed based on organs and systems,with a focus on the integration of basic and clinical research from the early stage.It adopts a diversified and student-centered teaching method,with practice teaching running through the whole course.Moreover,it attaches importance to family medical education and strengthens the cultivation of medical humanities.Learning from the advanced teaching concepts and methods in North America may help to promote the reform of medical education in China and cultivate high-quality medical talents in line with international standards.

Objective To explore patients' experience in the orthodontic orthognathic combined treatment outpatient service.Methods Purposive sampling method was used to select 6 patients who were admitted to the orthodontic orthognathic combine treatment outpatient service in Shanghai Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine in February 2017. Research data were collected in the form of face-to-face and semi-structured in-depth interview, and analyzed by Colaizzi content analysis.Results In the research, 3 topics were extracted: patients experience, communication experience, and waiting experience.Conclusions The orthodontic orthognathic combined outpatient service provides convenience for patients and plays an significant role in the diagnosis and treatment of disease. However, there is still room for improvement in the service of combination outpaitent.

AIM:TostudythefunctionofmicroRNA(miR)-19aandmiR-92abyseed-targetinginhibitionin multiple myeloma cells and their signal pathways .METHODS:The experiments were divided into t-antimiR-19a group, t-antimiR-92a group, scramble control group and blank control group .The growth-inhibitory potencies were measured by MTT assay.The ability of cell colony formation was measured by cell colony formation assay .The ability of cell invasion was measured by Transwell experiment .The miR-19a and miR-92a target gene signal pathways were integrated by miRFo-cus software.RESULTS:MTT assay showed that t-antimiR-19a and t-antimiR-92a significantly inhibited the viability of multiple myeloma cells , and the best concentration and time were 0.5μmol/L and 48 h, respectively .The colony number in t-antimiR-19a/92a group was less than that in scramble control group .The transfection with t-antimiR-19a or t-antimiR-92a effectively decreased the cell invasion , as the relative invasion cell number was significantly decreased compared with scramble control group.miR-19a and miR-92a were involved in mTOR signaling, cell cycle and other cancer pathways . CONCLUSION:miR-19a and miR-92a cluster might be a potential target for therapeutic intervention in multiple myelo-ma.

[ABSTRACT]AIM:ToinvestigatetheroleoftinyantisensenucleicacidagainstmiR-155(tinyantimiR-155, t-antimiR-155) in multiple myeloma cells .METHODS:According to the seed sequence of miR-155, t-antimiR-155 was designed and synthesized .t-antimiR-155 was transfected by Lipofectamine TM 2000 into RPMI-8266 cells.The cells were di-vided into t-antimiR-155 group, scrambled control (SCR) group and blank control group .The growth-inhibitory potencies were measured by MTT assay .The ability of cell colony formation was detected by cell colony formation assay .The cell ap-optosis was assessed by flow cytometry with annexin V /PI double staining .RESULTS: The best concentration and time were 0.4 μmol/L and 48 h, respectively.The cell colony forming experiment showed that the circumstances of forming cell community in t-antimiR-155 group was weaker than that in SCR group , and the colony formation inhibitory rate of former was significant higher than the latter .Compared with SCR group , the cell apoptosis in t-antimiR-155 group significantly in-creased.CONCLUSION: The t-antimiR-155 inhibits the progression of multiple myeloma cells by interfering with miR-155.miR-155 may serve as a potential target in gene therapy for treating multiple myeloma .
