Objective To compare treatment and efficacy of thoracolumbar fractures by using three different screw fixations:traditional approach,the vertebral side clearance into the road and percutaneous pedicle. Methods A total of 82 single segmental thoracic lumbar fractures cases hospitalized from March 2011 to March 2014 ,with male 67 cases ,female 15 cases ,and average age(33.7+/-12.5)years old. Patients were randomly divided into three groups:traditional approach group (n = 23),operation through paraspinal muscle gap group (n = 30),percutaneous group(n = 29). These following indicators will be compared in three groups:duration of operation ,intraoperative blood loss ,intraoperative fluoroscopy time ,postoperative flow ,VAS scores before and after operation and Oswestry disability index , difference of spinal sagittal position Cobb′s Angle. Results Compared with the traditional approach group ,operation through paraspinal muscle gap group and percu-taneous group have obvious advantages in duration of operation,intraoperative blood loss,postoperative flow,VAS scores before and after operation ,the Oswestry disability index. Additionally ,above mentioned three surgical methods could recover kyphosis deformity ,and there was no statistically significant difference among three groups (P > 0.05). Conclusion In the treatment of monosegmental thoracolumbar fractures ,compared with traditional approach ,operation through paraspinal muscle gap and percutaneous pedicle screw internal fixation have more advantages which includes fewer trauma,less bleeding,faster recovery and lower incidence of postoperative low back pain.

RNF180 is a novel membrane-bound E3 ubiquitin ligase that participates in cell development,proliferation and apoptosis.It is a tumor suppressor gene that inhibits cell proliferation and induces apoptosis and may inhibit gastric cancer cell lymph node metastasis.The study found that RNF180 gene methylation and gastric cancer is closely related to the occurrence and development.Therefore,RNF180 gene methylation is expected as a tumor marker of gastric cancer for early diagnosis and prognosis of gastric cancer.In this paper,RNF180 on the diagnosis of gastric cancer research progress made a review.

Objective To improve the effects of health education(HE)and satisfaction degree on HE of inpatients by executing hierarchical full-responsibility nursing. Methods Fourteen wards were randomly chosen form the hospital and divided into the control group and the experimental group, each group having 7 wards. The control group carried out routine holistic nursing model, and the experimental group carried out a new hierarchical full-responsibility nursing system. Reforming nursing scheduling and diminishing the nursing unit to assure that the patients acquired the continous and stable nursing service when they were in hospital. The effect and the degree of satisfaction of HE were compared between two groups after 6 months. Results The effects of HE in the experimental group were significantly better than those in the control group, and the degree of satisfaction on HE in the experimental group was much higher than in the control group. Conclusions The hierarchical full-responsibility nursing system can give patients systematic and normalized HE. It can significantly improve the effects and the degree of satisfaction on HE.

Objective To investigate the damaging traits of cognitive function in first episode depression patients with the assessment of neuropsychological status ( RBANS) and Stroop Color-word Test. Methods Two hundred and thirty first-episode depression patients as experimental group and one hundred and seventy-eight health person as control were evaluated separately by repeatable battery for the RBANS and Stroop Color-word Test. Results In Stroop Color-word Test,the time required for completing the words,color,double-word,two-color in depression patients ( (14.37 ±6.65)s,(21. 58 ±8. 70) s,( 16. 56 ±8. 23)s, (37. 88 ± 13. 67) s) were longer than the control group ((12.38 ±3.34)s, (18.01 ±5.51) s, (14. 17 ±4. 37) s, (32. 87 ± 10.28) s). The difference between the two groups was found in cognitive function in first episode depression patients (P ＜ 0.05). The scores of color interference and meaning interference were no difference between the two groups (P＞0.05) . The patients'scores of the RBANS test in all items( (72.19 ± 17.22), (80.89 ± 15.29), (82.00 ± 16.37) , (98.74 ± 17.01) ,(82.09 ± 14.62) )were significantly poorer than those in healthy controls. Compared with control group, scores of the scales were significant difference between two groups. Pearson correlation analysis showed that RBANS total score and five factors had no correlation with HAMD total score and factors. It positively correlated with education level (P＜0.05) ,but not with sex (P＞0.05). Immediate memory,verbal function,delayed memory in five factors and RBANS total score negatively correlated with age and course of disease respectively, but breadth of vision,attention were not did(P＜0.05). Conclusion First-episode depression patients suffer from more serious and comprehensive damage of cognitive function such as memory,attention,executive function.

Objective To examine the different effects of impulsive and aggressive personality on college students' suicide attempt. Methods Four thousand nine hundred eighteen sophomores and juniors were selected according to the principle of cluster sampling from Beijing agricultural university and Beijing university of information science and tech?nology. Four thousand seven hundred ninety-seven of them completed the survey. Their impulsive and aggressive person?ality were evaluated by the Barratt Impulsiveness Scale-Chinese Versions (BIS-CV) and the Buss-Perry Aggression Questionnaire-Chinese Versions (AQ-CV). A self-made questionnaire were used to investigate suicidal idea and self-in?jury/suicidal behavior of college students. Results Among the sophomores and juniors, 18 participants had self-injury/suicidal behavior (3.75‰) and 1843 had suicidal idea (38.42%). Compared with the students who didn’t have self-inju?ry/suicidal behavior, those who once had self-injury/suicidal behavior had significantly higher BIS-CV score (P<0.01) and higher scores of non-planning and motor factors (P<0.05). They also had significantly higher score in AQ-CV and the factors of physical aggression, verbal aggression, anger, hostility and pointing to the self attacks (P<0.01). Conclu? sions The college students with self-injury/suicidal behavior have higher tendency in impulsive and aggressive personali?ty. Therefore, it is necessary to prevent suicide behavior, form high impulsive and aggressive intention and behavior.

Objective To investigate whether paclitaxel can efficiently induce the apoptosis of ovarian cell HO-8910,and to study the relationship between the apoptosis of cells and the cell cycle.Methods With the treatment of paclitaxel with different concentrations and different time,the morphologic change of HO-8910 ovarian cells was observed using fluorescence microscopy and transmission electron microscopy(TEM),and the apoptosis of cells and the changes of cell cycle were determined by flow cytometry(FCM). Results The typical changes of HO-8910 cell apoptosis were observed by TEM and Fluorescence microscopy.With the treatment of paclitaxel,the HO-8910 ovarian cells were firstly arrested in G_2/M phase,and the typical ultrastructural changes of apoptosis were appeared only after the cells were apparently arrested in G_2/M phase.Conclusion Paclitaxel can induce the apoptosis of HO-8910 cells and the apoptosis is associated with the blockage of G_2/M phase in cell cycle.

Aim To investigate the role of endothe-lium in the enhancement of phenylephrine-mediated vasoconstriction by bupivacaine in the isolated rat aor-ta.Methods The isolated rat aortic rings were pre-pared, and the vascular endothelium was removed chemically or physically .Phenylephrine-mediated vas-oconstriction was recorded .Results A pretreatment with bupivacaine at 30 μmol · L-1 for 20 min signifi-cantly increased the Emax value of vasoconstrictive re-sponses to phenylephrine from 2.22 ±0.07 g of sol-vent-controlled group to 2.50 ±0.05 g ( P<0.01 ) in the isolated endothelium-intact rat aorta.However, the Emax value was not significantly changed by a pretreat-ment with bupivacaine at 30 μmol · L-1 for 5 , 10 or 15 min ( P>0.05 ) .A pretreatment with bupivacaine at 30 μmol · L-1 for 20 min slightly but significantly inhibited the vasoconstrictive responses to low concen-tration of phenylephrine in the isolated endothelium-de-nuded rat aorta (P<0.05).In the isolated endotheli-um-intact rat aorta under a combined treatment with in-dometacin, ChTX, apamin and L-NAME, the vasodi-lator responses to acetylcholine were completely sup-pressed , and a pretreatment with bupivacaine at 30μmol· L-1 for 20 min did not significantly affect the vasoconstrictive responses to phenylephrine ( P >0.05 ) .Conclusion Bupivacaine enhances α1-adre-noceptor-mediated vasoconstriction by inhibiting vascu-lar endothelium in the isolated endothelium-intact rat aorta, Which potentiates indirectly the vasoconstrictive responses to phenylephrine .

Aim To investigate the selective inhibition of ethanol on muscarinic receptor-or 5-HT receptor-me-diated contractile responses in the circular smooth mus-cle strips isolated from the different regions of rat stom-ach. Methods Circular muscle strips isolated from the rat gastric fundus, body, cardia and pylorus were prepared, and the contractile responses to carbachol ( CCh ) or 5-HT were recorded. Results Ethanol (0. 000 05~0. 000 5, V/V) did not affect the contrac-tile response to CCh in circular muscle strips from the rat gastric fundus and cardia, and that to 5-HT in the strips from rat gastric fundus and body ( P >0. 05 ) . However, ethanol(0. 000 1 and 0. 000 5) significantly inhibited the Emax value of the contraction by CCh from (12. 18 ± 0. 33) g of control level to (10. 88 ± 0. 41) g and -lgEC50 value from ( 6. 33 ± 0. 05 ) of control level to (6. 12 ± 0. 06)(P <0. 05) in the strips from rat gastric body. Ethanol(0. 000 1 and 0. 000 5) also significantly inhibited the Emax value of the contraction by CCh from (2. 87 ± 0. 15) g of control level to (2. 2 ± 0. 13) g and -lgEC50 value from (6. 49 ± 0. 10) of control level to (6. 05 ± 0. 09)(P<0. 01) in the strips from rat gastric pylorus. Moreover, ethanol ( 0. 000 1 and 0. 000 5) significantly inhibited the Emax value of the contraction by 5-HT from (2. 93 ± 0. 35) g of con-trol level to ( 2. 1 ± 0. 30 ) g ( P<0. 05 ) , but did not affect the -lgEC50 value in the strips from rat gastric cardia. Conclusions Ethanol inhibits the contractile responses to 5-HT only in the circular muscle strips of rat gastric cardia, and it inhibits the contractile respon-ses to CCh more strongly in the circular muscle strips of gastric pylorus than gastric body. In those gastric circular muscle strips, ethanol decreases both the ac-tivity and affinity of CCh to muscarinic receptors, but decreases only the activity of 5-HT to its receptors.

Objective To study the clinical significance of antinuclear antibody (ANA),anti-thyroid peroxidase antibody (TPO-Ab) and antithyroglobulin antibody (Tg-Ab),thyroid stimulating hormone (TSH),free triiodothyronine (FT3),free thyroxine (FT4) in patients with recurrent spontaneous abortion (RSA).Methods 46 women with RSA diagnosis in out patient department in Peking University Shenzhen Hospital from March 2015 to December 2016 were recruited as the study group,20 women with normal childbirth history were enrolled as the control group,ANA was detected by indirect immunofluorescence (IIF) assay and ELISA,TSH,FT3 and FT4 were detected by chemiluminescence immunoassay technology.Results The positive rates of ANA(IIF),TPO-Ab and Tg-Ab in patients with RSA were 24％,24％ and 15％ respectively which were significantly higher than those in healthy control (P＜0.05).Serum levels of TSH,TPO-Ab and Tg-Ab in patients with RSA were 2.70 ± 1.38 mIU/L,38.99 ± 10.18 IU/ml and 3.07 ± 1.69 IU/ml respectively,which were significantly higher than those in healthy cases (P＜0.05).Conclusion ANA and antithyroid antibodies were closely related with RSA.It is very important to screen ANA and antithyroid antibodies for etiological diagnosis and appropriate intervention in patients with RSA to reduce the incidence of abortion.

Objective To investigate the clinical significance of combined detection of serum CEA, SCC, CYFRA21-1 before and after radiotherapy in esophagus carcinoma. Methods 226 cases of esophagus carcinoma patient were collected from November, 2006 to December, 2008. ELISA was used to detect the serum CEA, SCC and CYFRA21-1 of patients with esophagus cancer before and after radiotherapy. SPSS13.0 was used for the statistical analysis. Results The positive rate of CEA, SCC and CYFRA21-1 was 11.1 %, 16.8%, 27.4 %, respectively and the combined positive rate was 39.8 % from 226 patient serums before radiotherapy. The longer the lesion length, the later the clinical stage,the deeper the tumor invasion, the higher the mean value of serum CEA, SCC, CYFRA21-1 was. The mean value was lower in the early stage. The mean value of CEA, SCC and CYFRA21-1 was found to be well correlated with tumor size, TNM stage and depth of tumor invasion. Among three tumor biomarkers, the individual difference of CEA and CYFRA21-1 was bigger and the pathological stage and prognosis correlation with CYFRA21-1 was the best. The biomarker value dropped to the level below the normal in 76.7% patient out of 90 cases after radiotherapy. Conclusion The combined detection of serum CEA, SCC, CYFRA21-1 may be used as adjuvant diagnosis for esophagus cancer and has better clinical value for prediction to treatment and prognosis.
