Objective To assess the clinical value of pre-operative embolization for nasopharyngeal angiofibroma. Methods 13 patients with nasopharyngeal angiofibroma confirmed by surgery and biopsy were retrospectively analysed. Bilateral carotid artery angiograpy was perfomed for demonstration of the arterial supply of tumor. According to the size and different caliber of arteries, embolization were seperately undertaken by different types of coil via 4.1or 5F Head-Hunter catheter. The embolization efficacy, embolization was evaluated by amount of blood loss. Results After coil embolization , no complication happened ranging 1～4 days (mean 2 days) in all 13 patients and then all the tumor masses were totally resected with mean blood loss of (584.6?379.4) ml (range 250～1500 ml). Conclusions Preoperative coils embolization is safe, reliable with less complication especially for reducing intraoperative blood loss and promoting the prognosis.

Objective To investigate the clinical characteristics and imaging manifestations of AIDS complicated with disseminated Penicillium marneffei (PM) infection. Methods A total of 12 patients with AIDS complicated with disseminated PM infection were collected and the symptoms, signs, laboratory examination results and image manifestations of these patients were analyzed retrospectively. Results (1) The diagnosis of PM infection in all the 12 cases were confirmed by peripheral blood culture.All the 12 cases (100％) had irregular fever (38-41 ℃) and enlarged lymph nodes, 8 cases (66％) had skin rashes; 8 cases (66％) had hepatomegaly; 9 cases (75％) had splenomegaly while 8 cases (66％) had anemia. (2) Imaging manifestation: Five cases manifested bilateral pulmonary disseminated miliary nodular shadows or lattice signs; 1 case showed enlarged hilar lymph node and 2 zases showed patchy shadow with pleuritis. One case presented sub-pleural curve line shadow at the posterior part of the right lower lung,and adhesion between the intestinal wall and intestinal mesentery in mass form in the abdomen by CT examination. Conclusion Patients suffering from AIDS (CD4T lymphocytes ＜50/μ L) with impaired immunity might be susceptible to complication of disseminated PM infection, which presents mainly damage of multiple organs and symptoms such as fever; enlargement of liver,spleen and lymph nodes, as well as specific skin maculopapular rashes. Imaging manifestations in the lungs were revealed as miliary nodular shadows and lattice-like shadows. Intensified abdominal CT might reveal presence of several enlarged postperitoneal lymph nodes and intestinal adhesion in shape of cakes.

Objective To discuss the feasibility of neuroendoscopic third ventriculostomy for chronic posttraumatic hydrocephalus (PTH).Methods Nineteen cases of chronic PTH treated with neuroendoscopic third ventriculostomy between October 2010 and October 2014 were analyzed retrospectively.There were 13 males and 6 females, aged 11-57 years (mean, 36.3 years).Trauma resulted from traffic accidents in 14 cases, falls in 4 cases and blunt object hitting in 1 case.Of the 19 cases analyzed, 5 had Glasgow Coma Scale (GCS) score of 13-15, 5 had score of 9-12 and 9 had score of 5-8 at admission.Results of operation were assessed with the Canada multicenter evaluation criteria.Prognosis was analyzed with the Glasgow Outcome Scale (GOS).Results All cases were followed up for mean 13.6 months (range, 6-26 months).Improvement of symptoms was achieved in 17 cases, but was not seen in 2 cases.Of the 2 cases, one required ventriculoperitoneal shunt two weeks after ineffective ventriculostomy, and one required second ventriculostomy one month after the presence of stoma blockage.No serious complications occurred.At follow-up, 9 cases had GOS score of 5, 8 cases had score of 4 and 2 cases had score of 3.Conclusions Neuroendoscopic third ventriculostomy is in line with the physical characteristics in cerebrospinal fluid circulation, which implies no shunt implantation, less operative trauma and less complications.The procedure is an effective approach for chronic PTH.

Objective To investigate and compare the clinical thinking ability of medical graduate students of different majors and different grades to explore the influencing factors of clinical thinking ability. Methods 180 graduate students in Medical College of Qingdao University were sur-veyed,including 54 nursing and 126 clinical medicine graduates of different grades. We used a self-designed scale of clinical thinking ability which included three main dimensions (critical thinking abil-ity, systematic thinking ability, evidence-based thinking ability) and twenty-four level 2 items. Ap-plying t test, ANOVA, multiple linear regression analysis for data statistical analysis. Results There's no significant difference comparing the scores of nursing graduates to the scores of clinical medical graduates(t=-0.80, P>0.05). However, there is significant difference in the different grade graduates (F=53.43, P<0.05). The multiple linear regression analysis shows that the practice time, reading professional literature quantity, and starting research earlier or later,are signif-icantly related to the clinical thinking ability(P<0.05). Conclusion The clinical thinking level of medical graduate students is generally high, and the higher grade, the higher level of clinical think-ing ability. We must strength-en the training of clinical thinking ability of medical graduates.

Objective:To investigate the effects of long-term exposure to chrysotile and crocidolite on miRNAs and epithelial mesenchymal transformation (EMT) -related gene expression in human pleural mesothelial cells.Methods:In November 2020, fluorescence quantitative polymerase chain reaction (RT-qPCR) was used to detect the expressions of EMT-related genes in human pleural mesothelioma cells (NCl-H2052 cells, NCl-H2452 cells) and human normal mesothelial cells (Met-5A cells). MiRNAs with abnormal expression in human pleural mesothelioma cells were screened out from the previous miRNA chip data of research group, and target genes of differentially expressed miRNAs were predicted using miRWalk database (http: //mirwalk.umm.uni-heidelberg.de). RT-qPCR was used to verify the abnormal expression of EMT-related miRNAs in cell lines. Met-5A cells were treated with 5μg/cm 2 chrysotile and crocidolite respectively for 48 h a time, once a week and a total of 10 times. Chrysotile group, crocidolite group and control group were set up. And the control group was added with the same volume of PBS. The expression changes of EMT-related genes and abnormal expression miRNAs in each group were detected by RT-qPCR. The differences among the groups were compared by one-way ANOVA, and the differences between the control group and the experimental group were compared by dunnet- t test. Results:Compared with Met-5A cells, the expression levels of Vimentin and Twist genes were increased, and the expression level of E-cadherin genes was decreased in NCl-H2052 cells and NCl-H2452 cells ( P<0.001). Target genes of miRNAs with abnormal expression in miRNA chip were predicted, and the results showed four abnormally expressed miRNAs associated with EMT and verified the expression of these four miRNAs in the cell lines. Compared with Met-5A cells, the expression level of hsa-miR-155-5p was increased in NCl-H2052 cells and NCl-H2452 cells, the expression levels of hsa-miR-34b-5p, hsa-miR-34c-5p and hsa-miR-28-5p were decreased in NCl-H2052 cells and NCl-H2452 cells ( P<0.001), which was consistent with the results of chip analysis. After exposure of Met-5A cells, it was found that compared with the control group, the expression levels of Vimentin and Twist genes, hsa-miR-155-5p, hsa-miR-34b-5p and hsa-miR-34c-5p in the crocidolite group were increased, while the expression level of E-cadherin gene was decreased ( P<0.05). Compared with the control group, the expression levels of Vimentin, Twist and E-cadherin genes in chrysotile group were increased, while the expression levels of hsa-miR-34b-5p, hsa-miR-34c-5p and hsa-miR-28-5p were decreased ( P<0.05) . Conclusion:Long-term exposure to chrysotile and crocidolite could cause Met-5A cells to produce miRNAs and EMT-related gene expression changes similar to mesothelioma cells.
