OBJECTIVETo perform a transcriptomics study in differential genes after Xianglian External Lotion (XEL) induced the recovery of drug-resistant Candida albicans strains sensitive to Fluconazole.

METHODSBroth microdilution antifungal susceptibility test was used to detect minimal inhibitory concentration (MIC) of drug-resistant Candida albicans strains induced by XEL. Transcriptome sequencing (RNA-Seq) was used to determine and compare the transcription of primary drug-resistant Candida aIbicans strains and sensitive strains induced by XEL. High expressed genes and signaling pathways strains were analyzed by gene ontology (GO) method.

RESULTSXEL could induce drug-resistant strains of the 6th generations to recover sensitivity. Transcriptome sequencing showed that, as compared with primary drug-resistant strains, there were 165 genes with up-regulated RPKM index and 144 genes with down-regulated RPKM index after XEL induction. GO analyses found that all genes were mainly classified as GO:0015903 (fluconazole transport).

CONCLUSIONSXEL could induce the recovery of drug-resistant Candida albicans strains sensitive to Fluconazole. By analyzing transcriptomes, authors speculated that XEL could recover strain sensitivity to fluconazole by opening fluconazole transport pathway.

OBJECTIVETo explore the relationship of bone cement distribution and the puncture angle in the treatment of thoracolumbar compression fractures with unilateral percutaneous kyphoplasty (PKP).

METHODSThe clinical data of 37 patients with thoracolumbar osteoporotic compression fractures underwent PKP between January 2013 to March 2014 were retrospectively analyzed, all punctures were performed unilaterally. There were 6 males, aged from 65 to 78 years old with an average of (71.83 ± 6.15) years; and 31 females, aged from 57 to 89 years old with an average of (71.06 ± 7.89) years. Imaging data were analyzed and puncture angle and puncture point were measured before operation. According to the measured data, the puncture were performeds during the operation. Distribution area of bone cement were calculated by X-rays data after operation. The effect of bone cement distribution on suitable puncture angle was analyzed; VAS score was used to evaluate the clinical effects.

RESULTSThe puncture angle of thoracic vertebrae in T8-T12 was from 28° to 33° with an average 30.4°; and the puncture angle of lumbar vertebrae in L1-L5 was from 28° to 35° with an average of 31.3°. Postoperative X-rays showed the area ratios of bilateral bone cement was 0.97 ± 0.15. Bilateral diffuse area were basic equal. Postoperative VAS score decreased significantly (1.89 ± 1.29 vs 7.03 ± 1.42).

CONCLUSIONThrough measure imaging data before operation with PKP,the puncture point and entry point can be confirmed. According the measured data to puncture during operation, unilateral puncture can reach the distribution effect of the bilateral puncture in the treatment of thoracolumbar compression fractures.

Objective This paper explored the effect of the early clinical exposure in im-proving medical students' cognitive aspects of the doctor-patient relationship. Methods (1)From 280 undergraduate students of Grade 2010 who participated in early clinical exposure of Xi'an Jiaotong University College of Medicine and 280 undergraduate students of Grade 2011 who did not participate in the early clinical exposure, we selected 140 students respectively to conduct a simple random sam-pling survey. The results were analyzed by SPSS after using Microsoft Excellsoftware for entry. Statis-tical methods selected χ2-test/Fisher exact test(P<0.05). (2)We had an interview to students,teachers leading the project, instructor,experts engaging in the study of the doctor-patient relationship by using focus group discussion and in-depth interview, and then using thematic analysis to analyze the data. (3)The main aspects of questionnaires and interviews were: details, activity participation/interest, general cognitive on the doctor-patient relationship, passion for profession, choice of career, the effect in improving medical students' cognitive aspects of the doctor-patient relationship and the suggestions and comments. Results The effective questionnaires collected from Grade 2010 were 134, and124 from Grade 2011.The participation rate of the undergraduates of Grade 2010(participating group) was 94.0%(126/134), while the interest rate of undergraduates of Grade 2011 (control group) was only 76.6%(95/124). Participating group had a better cognitive understanding of doctor-patient relationship than control group(P=0.0192). The activities had significant effects on choice of career(P=0.0002), and no effect on passion for profession(P=0.7372). There was statistically significant difference on their views of employment(P=0.0002). The key words for the interview were: not enough preparation before activity, not reasonable timing, teachers leading the project, stimulation of professional pride. Conclusions Early clinical exposure activities can be effective in improving medical students' awareness of the current doctor-patient relationship. Still we have some shortages in the activity, some more exploration and amelioration should be made in late stage.

OBJECTIVETo investigate the application of surface-enhanced laser desorption ionization time-of-flight mass spectrometry (SELDI) protein chip in diagnosis and Chinese medicie syndrome type researching of systemic lupus erythematosus (SLE).

METHODSEighteen female SLE patients of mild/moderate degree with yin-deficiency caused internal heat syndrome (YDHS) were enrolled in the treatment group, and 15 women healthy volunteers was set up as the control group. Using SELDI method, the pre-, mid- and post-treatment peripheral blood mononuclear cell (PBMC) protein fingerprint of them was created respectively, which was then managed to screen out the markers by using ZUCI-PDAS package for establishing a diagnosis model.

RESULTSStudy was completed in 15 cases of the treatment group with 2 cases dropped out and 1 case lost. Before treatment, 44 protein peaks in the treatment group were found significantly different to those in the control group (P<0.01), and the sensitivity and specificity of the created models, 10542 Da m/z and 2554 Da m/z, reached 100%. After a 12-week treatment, 30 peaks were found significantly different between the two groups (P<0.01), and the sensitivity of 3365, 7104, 3882 and 6796 Da m/z created peak models was 100%, its specificity being 93.33%. Comparing the 35 samples (pre-, mid- and post-treatment) got from the treatment group with the 15 samples from the control group, significant difference was found in 55 peaks (P<0.01), the sensitivity and specificity of the 7103, 3882, 7143 Da m/z created peak models was 100% and 91.43% respectively.

CONCLUSIONSignificant differences of PBMC protein expression patterns were found between SLE patients of YDHS and healthy persons at times of before, during and after treatment, suggesting that SELDI may be used as a new method to create the diagnosis model, and its application in effecter protein screening, activity scoring and Chinese medicine syndrome type researching are expectable and waiting for further study in depth.

BACKGROUND:Integrated Traditional Chinese and Western Medicine minimaly invasive treatment for halux valgus based on wrapped curtain method with “8”-shaped bandage and sub toe pad external fixation has been used for a long time in the clinic. This method abandons the internal implant fixationandexternal plaster fixation. After surgery, patients could take care of themselves. However, theactivity of the broken end may cause fracture nonunion, which once aroused scholars’ question. Recently, with the continuous improvement of foot biomechanics research, foot finite element model and applications become a reality.
OBJECTIVE:To evaluate thestability of osteotomy after the operation of wrapped curtain method with“8”-shaped bandage and sub toe pad external fixation on the basis of static finite element method.
METHODS:A young female volunteer with halux valgus was selected, whose body weight was 58 kg, and right foot halux abductor valgus angle was 24°; intermetatarsal angle was 13°; proximal articulator set angle was 7°; distal articulator set angle was 7°. CT was used to scan the right foot. ABAQUS software was applied to establish a finite element model of right foot halux valgus bone, and model of the first metatarsal neck minimaly invasive osteotomy was simulated based on wrapped curtain method with external fixation. Von Mises stress and displacement at the osteotomy endwere calculated.
RESULTS AND CONCLUSION:(1) The maximum stress was 0.067 MPa without external fixation, and the maximum stress was 1.258 MPa with the external fixation. Stress was mainly distributed in the outer edge of the osteotomy. (2) The maximum absolute displacement was 0.363 mm without external fixation, and the maximum absolute displacement was 0.716 mm with external fixation. The two largest displacements were both in the Z-axis direction. Statistical analysis confirmed that the four nodes absolute displacement and stress were significantly different (P< 0.01). (3) The maximum relative displacement was 0.101 mm. The maximum relative displacement was 0.046 mm with external fixation. The maximum relative displacement without external fixation was-0.102 mm and occurred in the Z-axis. The maximum relative displacement with external fixation was 0.110 mm and occurred in the Y-axis. (4) One-way analysis of variance confirmed that the four nodes relative displacements were not statisticaly significant in X-axisand Y-axis (P> 0.05). The four nodes relative displacements were statisticaly significant in Z-axis (P< 0.05). (5) These findings suggest that the external fixation based on wrapped curtain method after halux valgus surgery could effectively reduce osteotomy displacement. The moderate stress and elastic fixation are conducive to fracture healing.

OBJECTIVETo summarize the experience of urethral reconstruction using circular fasciocutaneous flap for the treatment of complex anterior urethral strictures.

METHODThe circular fasciocutaneous flap was harvested from the distal penile shaft or foreskin. Then the circular configuration was converted into longitudinal strip of skin which was rotated to ventral side to repair the exposured urethral strictures using the ventral onlay method. The surveillance protocol after urethroplasty was urination observation, regularly uroflowmetry and urethrography examination.

RESULTSFrom Nov. 2006 to Oct. 2012, 15 cases were treated. The mean age was 45 years (20-76 years) and mean follow-up period was 18 months(3 months-3 years). Stricture was caused by chronic urethritis in 4 cases, long-term urethral catheterization in 3 cases, transurethral perfusion chem other aphy in 3 cases, transurethral prostatectomy in 3 cases and hypospadias after surgery in 2 patients. The mean stricture length was 7.0 cm (3.5-12.0 cm). The overall success rate was 80.0% (12/15). Recurrence stenosis was noted in 2 cases and diverticulum formation in 1 case.

CONCLUSIONSThe penile circular fasciocutaneous flap can be used for anterior urethral stricture in nearly any length. The flap has the characteristics of hairless, adequate mobile and length, well-vascularized pedicle and easy to harvest. The onlay reconstruction provides excellent cosmetic results, less trauma, higher success rate. Therefore it should be one of the preferred techniques for complex anterior urethral stricture repair.

Objective To discuss the changes and significance of interleukin-17 (IL-17) in perioperative period of congenital heart disease patients with pulmonary hypertension. Methods A total of forty patients with congenital heart disease underwent cardiopulmonary bypass (CPB) were included in this study. According to the pulmonary artery systolic pressure (PASP), patients were divided into non-pulmonary hypertension group (group Ⅰ, PASP < 30 mmHg) and pulmonary hypertension group (groupⅡ, PASP≥30 mmHg). Blood samples were taken before anesthesia (T1), start CPB (T2), 30 min after CPB (T3), 6 h (T4), 24 h (T5) and 7 d (T6) after operation. The concentration of IL-17 was detected by ELISA. Arterial oxygen partial pressure [p(O2)] and arterial carbon dioxide partial pressure [p(CO2)] during the first five time points were recorded. Oxygen index (OI) and alveolar arterial oxygen tension difference (AaDO2) were calculated. Results The plasma IL-17 levels in perioperative period were significantly higher in group Ⅱ than those of group Ⅰ (P < 0.05). The highest concentration of IL-17 emerged at T3, then decreased gradually in both groups. At this time point, the OI decreased, and AaDO2 increased significantly in both groups. Compared with groupⅠ, the OI decreased, while AaDO2 increased at T5 in groupⅡ(P<0.05). Conclusion The high level of IL-17 promotes the formation of pulmonary hypertension in congenital heart disease and leads to the lung injury during CPB, which can be used as a clinical monitoring indicator of evaluating severity.
