Objective Comparing with traditional teaching methods of oral histopathology, to probe whether the interactive teaching system of the digital microscope can improve the teaching effi-ciency of experiment of oral histopathology courses. Methods The subjects were the 2010 grade students (40 students) and the 2011 grade students (38 students) majoring in stomatology of South Medical University, and they were evenly divided into 2 groups at random. In the first part of the ex-periment of Grade 2010, the teaching of traditional optical microscope was used in a group of experi-mental courses, and interactive teaching with digital microscope was used in the other group. In the second part of the experiment the two groups swapped the teaching method. While in the whole exper-iment of Grade 2011, traditional optical microscopes were adopted in one group, and in contrast, the interactive teaching system of the digital microscope was adopted in the other group. The P values of the 5 indexes were less than 0.05. After the courses, the 2010 grade students received the questionnaire survey and the 2011 grade students received the quiz about the experimental course, and then the evaluation results of the two groups were compared for t inspection, using SPSS software t test. Result The questionnaire results of Grade 2010 showed that the scores of digital microscope interactive group were higher than those of traditional teaching group in satisfaction with teaching , teacher-student interaction, classroom atmosphere active degree, learning interest, and the understanding of the teach-ing content. The experiment course content test results of Grade 2011 showed that the digital interactive group students averaged 46.26, while the average score of the traditional teaching group was 42.78%. The difference between the two groups had statistical significance, P=0.001. Conclusion Compared with the traditional teaching methods, the interactive teaching system of the digital microscope can enhance the academic grades, improve the teaching efficiency of experiment of oral histopathology courses, and elevate the teaching quality.

Objective To investigate the craniofacial morphologies of Sagliker syndrome.Methods Sixteen patients were selected in this study that was diagnosed by the Department of Nephrology and the Center of Dentistry of China-Japan Friendship Hospital.They were divided into 2 groups:Sagliker syndrome group(SS) including 8 patients,and secondary hyperparathyroidism group (SHPT) including 8 patients.Cephalometric radiographs were taken from all the 16 patients.Results The hard issue measurement results had shown that in ∠SNA,∠ANB,∠NA/PA,∠MP/SN,∠MP/ FH,∠SArGo,and ∠ArGoGn,there were significantly statistical differences between the two groups.The measurements of SS were greater than that of SHPT.The soft issue measurement results had shown that in ∠LL-Bs-Pos,∠AsUL-FH,UL-EP,and ∠AsUL-BsUL,there were also significant differences between the two groups.The measurements of SS were greater than that of SHPT.In ∠BsLL-FH,there were evidently statistical differences between the two groups:the measurements of SS were greater than that of SHPT.Conclusions The facial hard and soft tissue of the patients with Sagliker syndrome have the special changes in morphologies.

[Abstract ] Objective The spleen plays an important role in brain ischemia-induced cerebral injury.This study aimed to ex-plore the correlation of the spleen mass index with the neurological function scores and infarction volume following permanent occlusion of the middle cerebral artery ( pMCAO) in rats. Methods Thirty male SD rats were equally randomized into a sham operation, a 3-day brain ischemia, and a 7-day brain ischemia group.The pMCAO model was established by ligation in the right brain of the rats. Neurological function scores were obtained with the Longa 5-Point Scale at 0, 3, and 7 days after modeling, and at 3 and 7 days, the spleen mass index was calculated, the infarction volume measured by TTC, and brain histopathological changes evaluated by HE stai-ning. Results Compared with the 7-day ischemia group, the 3-day ischemia rats showed significantly reduced spleen mass index ([1.62 ±0.58] vs [0.87 ±0.59] mg/g) and increased neurological function score (1.00 [1.00, 1.25] vs 2.00 [1.75, 2.25]) and infarct volume ([18.67 ±7.92] vs [36.20 ±14.92]%) (all P<0.05).An extremely significant decrease was found in the spleen mass index of the 3-day ischemia rats in comparison with that of the animals in the sham operation group ([1.90 ±0.22] mg/g) (P<0.01).HE staining revealed more obvious pathological injury of the cerebral cortex in the 3-day than in the 7-day group.The spleen mass index was negatively correlated with the neurological dys-function score (r=-0.851, P=0.019) and infarction volume (r=-0.717, P =0.013). Conclusion In pMCAO rats, measure-ment of the spleen mass index contributes significantly to the preven-tion and improvement of ischemia-induced cerebral injury.

Objective To study the relationship between the expression of perforin, granzyme B and the cytotoxicity of NK cells, after NK cells were purified and expanded with different cytokines. Meth-otis It was detected that the mRNA expressions of perforin, ganzyme B from 8 donors, and the cytotoxcity of NK cells to target I(562 cells by competitive qualitative RT-PCR. Results The mRNA expressions of perforin, granzyme B by purified and expanded NK cells with different cytokines were markedly enhanced, and IL-2 +IL-15 group, IL-2 + IL-12 + IL-15 group were significantly higher than others. It is consistent that the relationship between the mRNA expressions of NK cells and the cytotoxicity of NK cells to I(562 cells. Conclusion The mRNA expressions of perforin, granzyme B of NK cells with different cytokines were obviously.

Objective To investigate factors impacting on local recurrence in cases of primary retroperitoneal liposarcoma (RPLS) after complete enbloc resection.Methods The clinical data of 47 cases of primary retroperitoneal liposarcoma were retrospectively analyzed.Results 3-year local recurrence rate was 62％.Single and multiple regression analysis showed preoperative needle biopsy,histological subtype,tumor size and capsular invasion were all risk factors related to postoperative local recurrence in primary retroperitoneal liposarcoma undergoing complete resection (P ＜ 0.05).Conclusion Preoperative aspiration biopsy,tumor poor differentiation,large tumor size tumor extracapsular spread all lead to high local recurrence rate after complete resection of primary retroperitoneal liposarcoma.

Objective To observe the protein expression , subcelluar localization of activated Pak 1 and its relation-ship with chromosome separation during meiosis in mouse oocytes .Methods Western blot was applied to analyze the expression of activated Pak1 (phosphorylated Pak1 at Ser204, pPak1Ser204 ) at different stages of meiotic progres-sion in semi-quantitative manner;immunofluorescent staining was employed to detect the sub-cellular localization of pPak1Ser204 and its spatial-temporal correlation with spindle and microtubule organizing centers (MTOC) during oo-cyte meiosis.Results pPak1Ser204 expression was found upon germinal vesicle breakdown (GVBD) in mouse oo-cytes which increased along with the meiotic progression , reaching peak level at metaphase Ⅰ( MⅠ) , which re-mained up to meiosis Ⅱ(MⅡ).From pro-metaphase Ⅰ(pro-MⅠ) to MⅠand at MⅡstage, pPak1Ser204was co-localized with MTOC key components , pericentrin and γ-tubulin on spindle poles, pPak1Ser204 was also distributed on chromosomes;During anaphase Ⅰ(AⅠ) to telophase Ⅰ(TelⅠ) progression, pPak1Ser204 was detached from chromosomes and MTOC, and mainly concentrated on the cleavage furrow.Conclusions pPak1Ser204 is expressed upon meiotic resumption in oocytes .It is a MTOC-associated protein which may regulate chromosome separation through participating the formation and maintenance of spindle apparatus .

Objective To evaluate the efficacy and safety of the conscious analgesia/sedation scheme with remifentanil and propofol on the elderly patients under gastroenterological endoscopic procedure. Methods Retrospective analysis was performed on 3 500 cases with remifentanil and small?dose propofol under gastroenterological endoscopic procedures, and the procedure achievement, effects of the narcotic, adverse reactions and satisfactory results were summarized. Results All procedures were completed successfully. The ratio of the patients whose intended sedation depth arrived at referential induction was up to 91?3%(3 196/3 500).Hemodynamic change was slight and almost all patients could open eyes in no time, with short hospital stay. No serious adverse effects were observed except several patients complaining about mild bucking, abdominal distension and stomachache. The degree of patients′ satisfaction was high. Conclusion The conscious analgesia/sedation scheme with remifentanil and propofol can be effectively and safely used on gastroenterological endoscopic procedure among the elderly, but precise monitor and timely treatment of complications are still needed.
