Objective To explore the influence on isthmic spondylolisthesis (IS) from lumbar vertebras facet joint orientation (FJO) variation. Methods The lumbar vertebras of 60 patients scanned by 16-slices spiral CT were collected, 30 cases with IS was defined as isthmic group;30 cases with normal lumbar vertebras was defined as control group, the FJO at L3-4, L4-5 and L5-S1 were measured in two groups. The difference between two groups were compared at three levels, the difference between both sides of the facet joint orientation also was compared;the measured data and the data of 60 patients from foreign literature were compared at three levels. Results The FJO in isthmic group were (47.9±6.3)° ,(37.5±7.3)° , (37.9±7.7)° at the right of L3-4, L4-5, L5-S1 levels respectively,the FJO in control group were (53.1 ± 7.3)° , (40.5±6.3)° , (38.5±7.3)° respectively, the FJO in isthmic group were (48.1±6.0)° , (37.9 ± 7.4)° , (37.6 ± 7.6)° at the left of L3-4, L4-5, L5-S1 levels respectively, the FJO in control group were (52.3 ± 7.6)° , (41.6 ± 6.0)° , (38.2 ± 7.2)° respectively. The significant difference was found at L3-4 and L4-5 levels (P < 0.05), the orientation was similar at L5-S1 level (P > 0.05). The difference between the both sides FJO of lumbar vertebras was not found at L3-4,L4-5 and L5-S1 levels (P >0.05). The same as the measured data and the corresponding data from foreign literature(P > 0.05 ). Conclusions It seems possible that the coronal FJO may be the phenotypic representation of the familial etiology of IS. It is helpful for the measurement of lumbar vertebras FJO to find IS early,it is important to reduce and release the IS.

OBJECTIVETo compare the clinical effect and complications of subfascial breast augmentation and submammary breast augmentation.
METHODFrom Sept. 2009 to May 2012 , 25 patients with subfascial breast augmentation and 31 patients with submammary breast augmentation were observed. The postoperative results including visible implant edge or ripple, upper pole of the implant and long-term implant ptosis were compared respectively. The complications including hematoma, infection and capsular contraction were also recorded.
RESULTS56 cases were followed up for 2 months to 26 months. The incidence rate of visible implant edge or ripple was 4.0% (1/25 ) in the subfascial group and 29.0% (9/31) in the submammary group, showing a significant difference between them ( PC 0.05). The incidence rate of convex upper pole of the implant was 8.0% (2/25) in the subfascial group and 35.5% (11/31) in the submammary group, showing a significant difference between them ( P < 0.05). Long-term implant ptosis was not found in the two groups. The incidence rate of hematoma was 4.0% (1/25) in the subfascial group and 6.5% (2/31) in the submammary group, infection was not found. The incidence rate of capsular contraction was 8.0% (2/25) in the subfascial group and 12.9% (4/31) in the submammary group, showing no statistical difference between them ( P > 0.05 ).
CONCLUSIONSSubfascial breast augmentation has more clinical advantages compared with submammary breast augmentation, but no evident difference was found in the common complication rate, such as capsular contraction.

First aid skills are very important in the process of disaster medical rescue methods. Some first aid skills is rarely applied in clinical work at ordinary times, resulting in relevant medical personnel grasp of these skills being not enough skilled. This training method combined with the sim-ulator, has the characteristics and advantages of being close to the real, operational and repeatable. The main training program consists of 6 basic skills such as ventilation, hemostasis, bandaging, fixing, handling, basic life support. By simulating the real disaster scenario and simulation cases, we have targeted a single first aid skills training and multiple comprehensive ability training of first aid skills to trainees. To evaluate the training effect we have examined the individual skills of our trainees, with excellent performance as the goal, and in the comprehensive skills ability assessment we have paid attention to the emergency team's team cooperation ability. By the application of comprehensive simu-lation training and evaluation, the trainees can master all kinds of first aid skills in a short period of time.

Objective To analyze the influencing factors of having clinical meaningful recanalization (CMR)after revascularization therapy in acute phase of ischemic stroke. Methods A total of 267 consecutive patients with ischemic stroke admitted to the Department of Neurology,Xuanwu Hospital, Capital Medical University and received intravenous thrombolysis or endovascular intervention in acute stage from March 2011 and March 2015 were enrolled retrospectively. CMR was used as a primary endpoint event. They were divided into either a CMR group (n = 92)or a non-CMR group (n = 175)according to whether they had CMR. The baseline data of the patients in both groups were compared by using the Rank sum test and Pearson Chi-Square test. A multivariate logistic regression model was established to analyze the independent influencing factor of CMR. Results The median (interquartile range)age of 267 patents was 60 (51 -69)years,and 69 of them were females (25. 8%);the median (interquartile range)time from onset to treatment was 250 (195 -305)min,and the median (interquartile range)NIHSS score was 10 (6 -15). The baseline NIHSS score,body mass index,blood glucose level,and proportion of diabetes of the CMR group were significantly lower than those of the non-CMR group (all P≤0. 05). The results of multivariate logistic regression analysis showed that the baseline NIHSS (OR,0. 93,95% CI 0. 88 -0. 98;P = 0. 01),intravenous thrombolysis (with respect to endovascular intervention)(OR,0. 35, 95% CI 0. 17 -0. 73;P = 0. 01),and baseline blood glucose (OR,0. 87;95% CI 0. 77 -0. 98;P =0. 02)were the independent negative predictors of CMR. Conclusion The baseline NIHSS,intravenous thrombolysis (with respect to endovascular intervention),and high blood glucose are the negative influencing factors for achieving CMR in the acute phase of ischemic stroke,suggesting blood sugar intervention and endovascular intervention in acute phase may contribute to the improvement of clinical prognosis.

AIM: To investigate the effect of fetal bovine serum (FBS) on the proliferation and differentiation of murine corneal epithelial cells in vitro.METHODS: Mouse corneal epithelial cells(MCEs) were cultured in serum-free low-Ca2+ medium(KSFM) and KSFM supplemented with 100mL/L FBS, respectively. Population doublings (PDs) were determined. The expressions of corneal epithelial cell markers p63, keratin 19 (K19) and involucrin were investigated by RT-PCR and Western blotting analyses. RESULTS: Cells in KSFM were stably subcultured over 25 passages; however, none of the cell lines could pass P3 in KSFM with FBS. In KSFM, the cells showed typical cobblestone appearance and expressed p63, K19 and involucrin. After medium was supplemented with FBS, cells became homogeneous, large and squamous. Furthermore, both RT-PCR and Western blotting analyses showed that the expression of involucrin was increased significantly.CONCLUSION: FBS has effects of inhibiting proliferation and triggering differentiation of MCEs.

mRNAs of alpha-adrenoceptor (α-AR) subtypes are found in neurons in dorsal root ganglion (DRG) and change after peripheral nerve injury. In this study, the distribution of α-AR subtype proteins was studied in L5 DRG of normal rats and rats with chronic constriction injury of sciatic nerve (CCI). Using immunofluorescence technique, it was found that α1A-, α1B-, and α2A-AR proteins were expressed in large, medium, and small size neurons in normal DRG, and significantly increased in all size neurons 14 days after CCI. α1D- and α2C-AR was also expressed in all size neurons in normal DRG. However, α1D-AR was significantly increased and α2C-AR was decreased in small size neurons 14 days post CCI. α2B-AR neurons were not detectable in normal and CCI DRG. Co-expression of α1A- and α2A-AR in the same neuron was observed in normal DRG and increased post CCI. Collectively, these results indicated that there is distinct distribution of α-AR subtypes in DRG neurons, and the distribution and levels of expression of α-AR subtypes change differently after CCI. The up-regulation of α-AR subtypes in DRG neurons may play an important role in the process of generating and transmitting neuropathic pain.
